Moveable cover or awning
Technical Field [0001] the invention relates to a covering system, more specifically, the invention relates to a kind of such as for providing anti-sun, rain-proof protection of the canopy or awning system. Background Art [0002] usually need to provide covering open locality provides rain-proof and/or preventing protection covering, in order to enable people to enjoy open air and is not influenced by the disturbance of the weather. The use of retractable covering, for example, in order to cover the outside of the hotel, in private gardens, yards small seat is very usually the places. But using retractably covering these examples and other large places, for example, children's amusement places or campground, outdoor swimming pool, amphitheatre and open sportsgrounds needs and existing these system completely different system. Of particular interest, this covering system can be very easily and quickly installed and dismantled in order to suitable for particular climatic conditions, in order to produce the minimum destruction of the user. Also hoped that the single covering system can cover with a relatively large area, so that does not require the use of many small system combined (this not only in the visual is not beautiful appearance and assembling efficiency is low and not convenient). [0003] the need to use the large cover is another kind of situation. Some plantation, field or vineyard-network for, plastic film covering, in order to provide protection and superior to the crop cultivation conditions. [0004] in the field many covering system is known. Some systems there is no fixed (free standing), and some other need to be connected to the building or vehicle. United States Patent 5441068, discloses a can be fixed on the ground of the ceiling of the upright posts. In the open position is spaced around the upright post many of the supporting arms to support the ceiling thin film, and the column can be close to or in order to downwardly and when required, to the removal of the shade. However, the shortcoming of the umbrella-shaped ceiling is that these systems require stable and often is of large volume and a base, the base is usually necessary in the covered places play a role in or near the center of the. And, these shades are often relatively small, hence the need for many places for covering larger. [0005] another type of covering system utilize in place of the but capable of extending of the cover. [0006] United States Patent 5924465 is used for the awning of the vehicle an example of the system. It includes a winding on the reel of the awning; extending from each side of the vehicle in order to support each side of the awning supporting arm; the connection between the projection and the vehicle chassis in order to support the side of the supporting arm bracket; is fixed on the ground and to support the side of the upright post of the arm. The awning can be unfolded and the support member and set up on the bit, and then retracted and remove when necessary. United States Patent 6494246, also discloses a retractable awning, it can be connected to the vehicle or building. The awning from the roll on the reel. One end thereof is fixed on the structure (vehicle or building), and the distal end of the spool is connected to the drum and supported by a bracket, the bracket in the drum reel and the structure between the lower part of the extended position at a certain angle. Many other can be retracted is supported and set up in the the awning in order to support the canopy, and is connected to the structure at one end. [0007] US Patent 6557612, discloses a is used for supporting the awning specific articulated arm, in the awning is retracted and unfolding and folding it can extend the same. [0008] use of the supporting arm, bracket and the pillar in order to support the covering of this kind of system has many shortcomings. First of all, their heavy weight and large volume is, so that they can only has a limited size and the area of the covers relatively small. This also means that the installation and remove them very difficult and very time consuming and, when the weather conditions change need to provide this is obviously not desired. The support arm and the bracket may not be beautiful, but need in the known supporting covering in the system and prevent its sagging, this is particularly important for large-scale of the cover. [0009] another known system from French Patent 2559527 number. The disclosed mechanism is configured for rolling up, in the horizontal or slightly inclined to the plane of the sun shade canopy and extension. The roll-up mechanism, a, traction and canopy tightens many purpose. The rolled on the rotation of the reel and at the same time spreading the canopy (but opposite direction) is rolled up by the two transverse pulley and two return a set of the cable guide pulley, pulling its is provided with one or a plurality of traction buffer is comprized of the spring. These elastic to the cable to the canopy and provide a constant and gradually increasing tension, therefore, the canopy is always stretched. The end of the reel, a group having a different diameter annular pulley compensation of the different thickness of the dragon. [0010] as can be seen, this kind of system does not need the large heavy support arm and a bracket supporting the covering, two cables rather than maintain its tension and spring to provide tension. The cable must be thin enough to be coated around the small-diameter ring-shaped pulley. This system is not suitable for large-scale covering of heavy load, at least because it relies on a thin cable keep the tensioned state of the covering. Tensioning of the covering can be of the spring also limited by the size of the of stretch. And the tensile strength of the covering device is controlled by the restriction. So this kind of system is obviously only suitable for small light weight, having sufficient tensile strength of the covering, and is used for supporting the needs of supporting and anti-sagging device for large-scale covering is very unsatisfactory. [0011] WO 2004/011760 discloses a rolled curtain, wherein the two fabric common in reel key slot type , the spool to move along the guide track or a wire rope, at the same time two fabric coiling or uncoiling. The system is composed of a spring device to provide tension of the fabric. This is why the for it is not suitable one of the reasons why a larger application. Content of the invention [0012] the purpose of this invention is to provide system, it is able to cover large places, at the same time using less tangible element keeping simple. [0013] according to the 1st aspect of the invention, to provide a covering device for outdoor places, it includes between a retracted and an extended configuration of the covering, the covering having a front portion and the back portion, the back portion is connected to support 1st, the device also includes the support to the corresponding the 1st 2nd support extending of a plurality of longitudinal flexible element, and when the covering from a retracted configuration to the extended configuration when in operation, of the front surface of the covering part by the longitudinal flexible element supporting, wherein the covering the front of the part is in a movable manner in the longitudinal flexible element, so that between a retracted and an extended position when in operation the front portion of the flexible element moves relative to the longitudinal direction, and wherein at least one of the clamping system is arranged in the cover on the front of the part, is used for the front part of the way to be detachably fixed in the longitudinal flexible element on at least one of. [0014] the 1st support is usually the side of the building or vehicle, but it could also be a fixed-free, and may include a plurality of components such as a pillar. It also may be a building or a large-scale open stadium roof. [0015] preferably, the longitudinal flexible element is retained in the tensioned state. The longitudinal flexible element can be used for a firm tensile element, such as a wire rope or a metal (for example, steel) rope. As can be seen, these components can be directly supported by the front portion of the covering, the FR2559527 in, fine cable only maintain its in tensioned state and does not provide any direct vertical support. Therefore, this apparatus, unlike the prior art by the covering, as limited by its own tensile strength. Moreover, the present invention provides support also prevents sagging of the covering and even large, this using FR2559527 is the method of stretching the cannot be realized. [0016] in the preferred embodiment, the length of the covering is not stored in one end of the device. More preferably, for example, in order to roll up manner with the longitudinal direction of the flexible element in separate housings, in order to the longitudinal flexible element does not bear the weight of any unnecessary. [0017] the advantages of this invention as stated above is, around the covering does not require any supporting frame. The only required that the supporting structure of the support and 1st 2nd support. For example, in the arrangement of the rectangular cover, this can be only four fixed-position, each for each corner of the covering, i.e., in the two longitudinal flexible element one of the opposite ends of the support and a 2nd 1st support. [0018] according to another aspect of the invention, to provide a covering device for outdoor places, it includes between a retracted and an extended configuration of the covering, the covering having a front portion and the back portion, the back portion is connected to support 1st, the device also includes the support to the corresponding the 1st 2nd support extending of a plurality of longitudinal flexible element, wherein when the covering from a retracted configuration to the extended configuration when in operation, of the front surface of the covering part by the longitudinal flexible element supporting, wherein the covering the front of the part is in a movable manner in the longitudinal flexible element, so that between a retracted and an extended position when in operation the front portion of the flexible element moves relative to the longitudinal direction and supported by the longitudinal flexible element, and wherein the longitudinal elements each include the tensioned state of the steel wire rope. [0019] when the desired covering large-scale place and the covering system having a long SPAN, need, the need to increase the tension of the wire rope in order to prevent them from sagging too much. When the covering is the only when the tension in the wire rope, therefore, when the cover is retracted, the tension of the wire rope in order to prolong its service life can be reduced. Therefore, preferably, the longitudinal direction of the tension in the flexible element can be changed. [0020] in order to avoid longitudinal flexible element in large SPAN is sinking, can be used for the wire rope of the tube through a series of longitudinal flexible element of each structure, the tube is stretched to provide a tension and the two ends of the clamp. In this kind of flexible elements in the longitudinal direction of the tube to provide additional rigidity and the longitudinal flexible element can be across a large distance and reduce sinking. This longitudinal component is another advantage of the tension in the wire rope through the provided to form compressed the tube. Therefore tension does not need to be provided by the 1st and 2nd support, and does not need to be any additional lanyard. Such a system also is not limited to the structure of the existing can be, for example, the wall of the building or roof, the tension can be provided. [0021] preferably, the steel wire rope and spaced inside of the tube so that the wire rope cannot be moved transversely in the tube. Alternatively, the pipe can have just large enough to accommodate the diameter of the wire rope. The outer diameter of the tube can be on the basis of the longitudinal element is selected the required strength. Preferably, the tension of the wire rope can be adjusted according to the need. For example, when the covering system is the tension in the wire rope can be increased, and the system can be reduced when retracted. [0022] through a series of pipes for forming a wire rope of the longitudinal element is another advantage of the, the pipe can be used for providing the friction of the rough surface. For example, the tube can be coated with rubber. Alternatively, the pipe can have and tooth the covering can be mounted on a reel, the reel and geared joint along the longitudinal element driving the covering. In this way the covering can also be from the horizontal surface extending at a certain angle. [0023] 2nd support can be set up and along a plurality of directions corresponding to a plurality of covering can set up to cover forming a multi-direction. In a preferred arrangement, in the absence of any of the 1st fixed on one side of the support can be arranged back to back and two covering extending along its opposite direction. [0024] in one form of the invention, the front portion is configured to slide relative to the tension member. Therefore, from another aspect, the present invention provides a covering device, it includes between a retracted and an extended configuration of the covering, the covering having a front portion and the back portion, the back portion is connected to support 1st, wherein the apparatus further comprises support to the corresponding from the 1st 2nd support extending of a plurality of longitudinal flexible element, and wherein the covering the front of the part is in a movable manner in the longitudinal flexible element, so that between a retracted and an extended position when in operation, the front portion of the flexible element moves relative to the longitudinal direction of the longitudinal flexible element and the support, and when the covering at least a portion of the extended position when unfolded in the front part of the flexible element by the longitudinal direction of the support. [0025] according to another aspect of the invention, to provide a covering device, it includes between a retracted and an extended configuration of the covering, the covering having a front portion and the back portion, the back portion is connected to support 1st, the apparatus further comprises support to the corresponding from the 1st 2nd support extending of a plurality of longitudinal flexible element, wherein when the cover is in the retracted and extended configuration between the operation, of the front surface of the covering part by the longitudinal element support. [0026] preferably, the device also includes the fixed on the covering part of the rigidity of the front surface of the transverse element. This prevents the front edge of the sink and reduce the lateral forces on the flexible element. [0027] some known covering system offers many fine steel wire rope, can be of light weight of the covering along its traction. These systems usually have the wire rope through the covering reinforced hole on the fabric from the wire rope obumbrans covering, or by applying it from the simple loop or hook suspension. These methods for small light weight of the system is adequate, wherein each of the wire rope does not need to bear a lot of weight and is relatively small. However, for less wire rope support the larger, heavier covering, needs much larger heavy load steel wire rope or cable in order to support the weight of the covering. Because of the relatively thick covering of the cable and the relatively heavy, reinforced hole, hook or coiled to provide too much friction, and impede the covering unfolded or retracted. [0028] therefore, preferably, the apparatus further comprises a scroll unit, it can be provided in each of the longitudinal flexible element in the form of a roller on the case, the roller unit (case) includes at least one, more preferably comprises two or more of the roller casing can along the longitudinal flexible element rolling roller. [0029] the roller the chassis can be individually mounted and can be along the longitudinal direction of the corresponding mobile independently of the flexible element. However, preferably, the roller is connected with the case via the transverse element in front of the part of the covering, the covering part can move in front of the is installed on the longitudinal flexible element. Any component in the transverse direction of the roller at one end of the case along its corresponding longitudinal direction of the flexible element (with the transverse element) to move together. [0030] to provide roller replaces the hole , the hook with the covering or coiled to reduce the friction between the longitudinal flexible element. When the need for a strong, relatively large diameter cable support is larger when the covering, this is very important. And, if the roller is the mechanization of, the covering can be pulled out along the longitudinal flexible element. As discussed in more detail below, the roller case preferably has the longitudinal flexible element sandwiched between them a roller and is biased, in order to clamp the longitudinal flexible element. This further increased the longitudinal direction of the roller and the friction between the flexible element, and allow longer on the covering is relatively heavy. [0031] the invention the clamping mechanism can be an independent roller. However, in the preferred embodiment, the chassis includes the roller of the clamping system, when the roller case is placed in the desired position in the case of the roller when the clamping in the longitudinal flexible element. After once setting the clamping, retracts the covering in order to accept the slack section generates tension in order to enable the covering to maintain tension and horizontal. Through the front of the covering part of the clamping in the longitudinal flexible element, much more can be applied to the tension on the covering. The tension solely by the retracting mechanism of the power, the clamping strength of the covering and limited by the strength of the material. Only the system of the prior art is provided by the spring tension, wherein the rebound strength, and thus the amount of the change of the spring. By stretching spring with change haulage of the covering, can not at all times and all the developed length to provide a constant tension. Therefore, the rebound of the spring at all times strength is reduced. [0032] if the covering not have sufficient tension, it will be flagged and also will be more susceptible to the influence of any wind. Preferably, the tension of the covering can be provided on the change according to the requirements. Clamping system may include a spring plate of the clamped position. [0033] in the clamping system of the available, the case is provided with the roller supporting case the roller on the flexible element in the longitudinal direction of the two upper roller and located on the longitudinal flexible element below the two lower roller. The lower roller can in an unpinched position and movable between a clamping position, in the non-clamping position, allowing roller chassis along the longitudinal flexible element smooth rolling, in the clamping position, the lower roller so that it is biased or pushed, the two upper roller to provide the pressure, in order to the longitudinal flexible element is clamped between the upper and lower rollers. Used for biasing or pushing the lower roller of the spring device can be, for example, helical screw, cam device, pneumatic or hydraulic device. [0034] in another kind of clamping system can be selected, the case is provided with the roller supporting case the roller on the flexible element in the longitudinal direction of the two upper roller and is used for clamping the longitudinal flexible element relative to the two side roller. The side roller can be spring, helical screw, cam device, pneumatic or hydraulic device to bias or from the non-clamping position to the clamping position. However in one specific preferred embodiment, the roller is arranged to the side of the case when the roller extends along the extending direction of the covering in order to free to move when pulled, but when roller chassis is along the retracted when pulling in the direction of the covering, clamping the longitudinal flexible element. Preferably set up release mechanism, the release mechanism is released from the clamping position in order to cover the side of the roller can be retracted. [0035] this kind of clamping this can include two opposite roller, each can rotate around the substantially vertical shaft. These shaft each to slidably mounted in slot, the slot in the end of the close to the front edge than the front edge of the most far away from the end of the the more close together. In this way, when the covering is extended, side to move away from the shaft of the roller and the roller to move freely, but when the cover is retracted, sides of the axis of the roller to move closer together, the longitudinal flexible element clamped between the side of the roller. [0036] these clamping this is believed to be independent of the invention is, therefore, according to another aspect of the invention, for the roller to provide a clamping device of the system, which comprises at least two in the longitudinal element on one side of the at least one roller and the 1st in the longitudinal element on the other side of the roller 2nd, sub-in, the 1st 2nd roller can towards the bias or push the roller, in order to divide this longitudinal element clamped in between the 1st and 2nd roller. [0037] on the other hand can see that, for the roller to provide a clamping device of the chassis, which comprises the support case the roller on the component in the longitudinal direction of the two upper roller and located on the longitudinal element below the lower roller. The lower roller in the clamping position and the clamping position is movable between, in the case of clamping position, allowing the roller along the longitudinal flexible element smooth rolling, in the clamping position, the lower roller is towards the two upper roller bias or push, in order to the longitudinal flexible element clamped in between the upper and lower rollers. Used for biasing or pushing the lower roller of the spring device can be, for example, helical screw, cam device, pneumatic or hydraulic device. [0038] according to another aspect of the invention, for the roller to provide a clamping device of the chassis, which comprises the support case the roller on the component in the longitudinal direction of the two upper roller, and can be no bias or clamping position to the clamping position relative to the two side rollers is, they are in the clamping position of clamping the longitudinal element. The side roller can be spring, helical screw, cam device, pneumatic or hydraulic device to bias or from the non-clamping position to the clamping position. However, in the specific preferred embodiment, the roller is arranged to the side of the case when the roller along the extending direction of the covering in order to move freely when pulled, but when the roller case when retracted by the pull in the direction of clamping the longitudinal flexible element. Preferred is also provided a release mechanism, the release mechanism from the side of the clamping position of the roller in order to cover the release of the side of the roller can be retracted. [0039] according to another aspect of the invention, to provide in order to cover the device, it includes between a retracted and an extended configuration of the covering, the covering having a front portion and the back portion, the back portion is connected to support 1st, the device also includes the support to the corresponding the 1st 2nd support extending of a plurality of longitudinal flexible element, wherein when the covering from a retracted configuration to the extended configuration when in operation, of the front surface of the covering part by the longitudinal flexible element support, and wherein the apparatus further comprises a flexible element in each of the longitudinal direction of the roller unit, each roller unit comprises allowing the roller unit along a corresponding flexible element moves the longitudinal direction of the at least two roller, and the roller unit in the desired position in the corresponding longitudinal direction of the clamping system of the flexible element. [0040] as is known in the field of in, in addition to actuation by hand outside covering system can also be power actuated. The system of the present invention can also be mechanized in order to make the covering can power are extended and retracted. In addition to the wheel cylinder and the covering outside the clamping in the case of the roller can be mechanized. [0041] in the system of the present invention, if the roller case of mechanized, it is necessary to a certain way the roller case the electric supply. This can be through the cable along the covering is arranged on the side surface of the roller in one of the chassis. Then along the of the covering of the cable part is arranged in front of the, electric power can be fed to the another roller case. However, with this method, if the covering is rolled up, the covering of the cable to enable the side surface of the cable significantly thickensed. Therefore, preferably, the covering of the cable from one side of the rear part of the covering to the front of the part of the diagonal opposite sides of the through the covering is. Therefore, at the time when the covering is rolled up, the cable are evenly distributed on the whole length of the drum, the thickness of the roller is uniform. This can make the cover drum by reducing the maximum diameter of the rolled up more effective storage of the covering. To realize this rolled covering of uniform diameter of the drum a selectable way cable is arranged such that: at the back of the covering from the side of the part of the diagonal line of each corner of the covering towards the center, and then from the center of the covering to the diagonal line of the mounting rollers of the covering of the chassis in front of the corner of the portion of the cable extends. Each of the transmission of power from the wires may be part of the covering to the corners of the back of the covering on the part of the in front of the diagonal line of the corner of the relative, the electric wire can be in the center cross, or transmitting power for each of the electric wire can be from the covering to the corners of the rear part of the covering on the same side of the corner of the front portion of, their change the direction of the centre. In the latter arrangement, two transmission power wire preferably being kept together, in order to help to keep X shape, thus reducing the whole diameter of the covering of the roll. [0042] the part of the back of the cover, the wire is connected to the external power supply. [0043] the above-mentioned transmission power through the covering is independent of the method of the invention is believed to be. Consequently, according to the further aspect of this invention, to provide a covering of the apparatus along the covering method of transmitting electric power, wherein the at least one power transmission cable from the back of the covering to the covering part of the front of the cover to the part of the transmission along the diagonal line. [0044] according to another aspect, the invention provides a connected with the reinforcing elements of the covering device for covering the method of strengthening of the covering, the reinforcing element from the rear of the covering to the covering part of the front of the cover to a portion of the cross over is diagonal line. [0045] the reinforcing element can be a wire, cable or metal strap. [0046] sometimes, when the coverings when the tension becomes too big, for example, in strong wind, the covering must be retracted in order to prevent it from being damaged. Therefore, in a preferred embodiment, the device also can have an automatic retraction system. [0047] the wind sensor for determining when the retract automatic retraction system of the covering is known. However, wind power is not of which is to increase the tension of the covering the only factors. The accumulation of rain water and snow tension of the covering is also increased, and cannot be detected by the wind-force sensor. [0048] accordingly, the present invention of specific preferred embodiments also include automatic retraction system, the automatic retraction system includes the detection covering tension of tension sensor and when retracted when the tension is exceeded the threshold of the covering. The tension sensor in one embodiment, the tension sensor directly detecting the tension of the covering. In one optional embodiment, the tension sensor detecting at least one longitudinal direction of the tension in the flexible element. The tension sensor may be arranged in the roller casing or can be located in one of the support. If it is located in the case of the roller, it can pass the clamping device for detecting the pressure of the gripping elements of the combination of the clamping device. [0049] the above-mentioned automatic retraction system of the invention is believed to be independent, therefore according to another aspect of the invention, to provide a is used for covering and automatic retraction system of the equipment, wherein the tension sensor detecting the tension of the covering of the apparatus, and if the detected tension exceeds a predetermined threshold value, then the covering is retracted. [0050] as mentioned above, the tension sensor can directly detect the tension of the covering, or it may be the support of the covering through the detection of the tension of the tension of the covering is determined. In this latter in a kind of arrangement, preferably, in the deployed or retracts the cover each time the calibration the tension sensor. [0051] when retracted is long when the covering is the covering of the large-scale covering system of the another problem is, retracted covering can be considerable diameter of the cylinder. The covering system in the past this is not a problem, because of the known covering system can not extend as far as the above-mentioned system. [0052] however, in order to avoid this kind of covering retracted of large diameter, this invention covers the preferred embodiment of the system provides a plurality of reel, when the retraction of the covering around the roll shaft winding. In one embodiment, is provided with two the synchronous drive the storage reel, in order to in such a way around the cover to provide the winding their oval cross-section. [0053] the reel can be made from 3rd drive reel driving, the 3rd drive the spool than the diameter of the storage reel is small and on to the the two reels in order to drive the contact between them. Optionally, the storage reel can be used drive belt or chain synchronous drive. [0054] in an alternative embodiment, the three reel in a triangular arrangement to provide and is synchronous drive, around the three reel to retract the covering, in this manner providing a substantially triangular cross section. [0055] by using a plurality of smaller storage reel instead of a single storage scroll, the cover system can be made into a more space effective. [0056] this kind of system is also believed to be of independent invention. Therefore according to another aspect of the invention, to provide a is used for covering the storage system of the system, including the covering sheet circles a plurality of the storage reel, and they are arranged in order to determine the cross section of the covering sheet. [0057] in this way, can be provided with a reel can be obtained in order to make the best use of the space, and the covering sheet can, to a very high degree of space efficiency of the storage. [0058] can be provided around the storage by the storage reel driving the flexible base member. The cover piece can be connected to the basic part. Optionally, the cover piece can be around the storage reel winding and is connected to the rear end of its own in order to form the closed ring around the reel. [0059] when the at least a storage reel is driven, in the advance of the formed on the rear end of the flexible base member or the fabric ring and the storage reel has sufficient frictional engagement, the cover plate or the base member also is driven and around the storage reel retracted. [0060] in a preferred embodiment, the storage reel and the covering sheet or the base member by the friction force between spring or plurality of spring is increased, the spring will bias on the storage reel. The friction force is also to be given to the reel sufficient tackiness to increase the surface of, for example, provided on the rubber tape reel Description of drawings [0061] the following will refer to the attached diagram to describe an example of the preferred embodiment of the present invention, wherein: Figure 1 according to the present invention showing the cover of the 1st embodiment of the system.
