Collapsible burglar-proof fire-escape ladder with separate release stations and safety belts with locking arms

The invention relates to a collapsible fire-escape ladder with safety belt, of which the side bars (A,S) consist of U-sections and the rungs (W) of a square tube. The rungs are fastened to the side bars by means of articulated connections. At the upper end of the ladder there is a device (J,K) which protects the ladder against theft. One or more separate escape stations or release stations can be installed by sawing through the outer bar (A) and by fastening a freeing pin (O) into the outer bar (A) above the cut. The freeing pin (O) has a collar (R) which replaces the material removed as a result of the sawing operation. The connection between the outer bar (A) and the escape or release stations is made by means of a locking plug (H) which is introduced into a hole in the outer bar (A) and a hole in the freeing pin (O). A safety belt (E) is fastened to the outer bar (A) by means of a blocking arm (B). For this, the blocking arm (B) is inserted into the outer bar (A) either from the upper end of the outer bar or via an insertion slot on the rescue station which corresponds to the width of the blocking arm. The widest blocking arm (B) is provided at the topmost station. Under this, the insertion slots become sequentially narrower so that the blocking arm can slide over the insertion slots located under it. The rungs (W) allow blocking against a swinging-out of the ladder over 90 DEG , in that their ends come into engagement with the walls of the side bars. The wall-fastening clamps (P) which fit with the inner bar (S) and which are fastened to the bar with the same bolt fastenings as for the rungs stabilise the ladder against lateral movement. <IMAGE>

Energy absorbing webbings

A tear-away energy absorbing webbing (10) is a one-piece webbing. The tear-away energy absorbing webbing (10) has a top layer load-bearing web (12) and a bottom layer load-bearing web (24). An energy absorbing portion (38) of the webbing has binder yarns (36) interlaced with the top and bottom layer load-bearing webs (12, 14). A sufficiently high load force applied to the webbing breaks the binder yarns (36) and tears apart the top and bottom layer load-bearing webs (12, 14). The energy absorbing portion (38) absorbs energy as it tears apart. The top and bottom layer load-bearing webs (12, 14) support the load force when the shock absorbing portion is torn apart.

Removable vertical fall arrest device

A vertical fall arrest device is disclosed which combines in a single unit the means to arrest a fall, the capability to automatically traverse intermediate support means provided along a safety line, and ease of attachment to or detachment from the safety line at any point throughout its length. In the attached condition, in which a safety line (30) is captured in retaining recess (60), the device is always in a ready state to lock-on to the safety line in the event of a fall. The device is removed from the safety line by depressing release catch (44) against spring pressure and at the same time pulling wheel (42) in a direction away from body member (41). Movement of the wheel must also be effected against biasing pressure. This combined operation creates an opening for withdrawal of safety line (30). When the external forces are relaxed, internal springs (47a and 47b) ensure that both the wheel (42) and the release catch (44) return to their fully locked conditions.

Vertical fall arrest safety device

A vertical fall arrest safety device travels along a rail of a vertical track and is configured for quick attachment and detachment anywhere along the rail. The device has a mounting body having side rail engagements configured for slidably engaging behind the edges of a rail of the vertical track in use. The engagements are spaced and staggered so as to receive the rail therebetween when the mounting body is at an angle, and then slidably attach to the rail when the mounting body is twisted into alignment with the rail. The device also has a lever pivotally coupled to the mounting body at a fulcrum. As such, when a downward force is applied to a connection point of a distal end of the lever, an opposite distal end of the lever frictionally engages the rail.

Ladder safety apparatus

A safety ladder that protects a climber from a fall is disclosed. The device provides a ladder having a plurality of rungs, an elongated channel having multiple flanges surrounding a passageway, a pair of the flanges defining there between a gap. A locking member is configured to travel upwardly in the passageway, the locking member having a beam, a cam section at one end portion of the beam and an eyelet that is positioned outside of the passageway. A cable connects a climber to the connector section. The cam section is configured to form an anchor with the channel in a locking position when a climber pulls down on the cable and locking member.

Fall arrest assembly

A fall arrest assembly that includes a rotational drum, at least one pawl and a catch is provided. The rotational drum is configured to rotate in response to a movement of a lifeline. The least one pawl is in rotational communication with the rotational drum. The at least one pawl is further configured to pivot about a pivot connection in response to select rotational velocities of the rotational drum. The at least one pawl is also configured to engage the catch when the at least one pawl pivots in response to the select rotational velocities of the rotational drum to stop the rotation of the rotational drum and movement of the lifeline. An elastic bushing for each pivot connection is also used. Each elastic bushing is positioned about an associated pivot connection of an associated pawl. The elastic bushings deform in shape as an associated pawl engages the at least one portion of the catch.

Catching device for a climbing safety system

A safety catch for an operator on a ladder or similar high working positions, has a slider (1) moving along a guide rail (B) fitted on the inside with locking tags (A). A locking lever (3) is pivot mounted (2) about its center of inertia inside the slider and has a roller (4) at the upper end and a braking profile at the lower end. The locking end is held in the retracted setting by a spring. The inertia of the spring is greater than that of the catch and is set to operate the locking action above a set downward speed of the slider. The locking action is failsafe with the locking catch in the locking position if the return spring breaks.

Collapsible platform assembly for an extension ladder

A collapsible platform assembly for an extension ladder is disclosed that can be used to support the top of an extension ladder with respect to a roof. The collapsible platform assembly includes a platform that is rotatably connected to a rung of an extension ladder near the top. In a storage or retracted position, the platform is generally co-planar with the ladder; i.e fits between the side rails of the extension ladder. In a use position, the platform can be extended and directly supported by the roof, either flat against a roof or alternatively at an acute angle relative to the roof. Since the platform is configured to be directly supported by the roof, the platform acts as a rigid support for the top of the ladder which does not deflect under load as there is an even weight transfer from the ladder to the platform in use. In accordance with an important aspect of the invention, an upper portion of the side rails act as “grab rails” when the platform is in an extended position, allowing the user to hold on and walk through the top of the ladder and onto the platform when the collapsible platform assembly is in an extended position. In one embodiment of the invention, one or more retractable hand rails are provided for added safety for use when the user moves onto the platform.
