Demanded 26 February 1958,k 4 to 16m, to Paris. Issued 20 July 1959, -Published 8 January 1960. The present invention relates to the controls mechanical type remote comprising a guide channel in which a flexible cable multi-strand having protrusions helical- [...] peripherally spaced revenue is mounted for- view a reciprocating motion and object of making such devices having front- additional stage and larger than those made. When it is advantageous or that it is suitable for the guide conduit to be placed at the intersection corners of two meeting surfaces for in- surround a dihedron, for example a aperture window there is a problem to adapt in this position a control of the type having a mechanical advantage and movement of cable suitable. The present invention relates to a device to overcome these disadvantages control wherein a toothed wheel meshes with the cable and is rotatable about an axis which is more or less into the bisector plane the angle of the dihedron between the surfaces, for the mounting and the manipulation of a handle crank of relatively large radius which can be operated in the region between the two said surfaces together forming the angle of the dihedron. According to the primary feature of the present invention, the control device comprises a housing extended metal, material-spla tick or other suitable hard material consisting in two parts hereafter referred to as the body and the neck- [...]. The body has back surfaces of forming an angle relative to one another (equal to the angle of the dihedron in which the device is to be mounted) and these surfaces form the external faces of two or thicknesses walls extending from one end to the other end of the body and which internally have more or less an angular disposition semiconductor- intraocular. A mi-path between the two ends of the body and to the inside is a hub provided with a hole for attachment of a spindle and having, the planar outer surface is in a plane parallel to the which can be viewed as the longitudinal axis of the body and forms a substantially equal angle with the planes of the rear surfaces of the body. A each end of the body, it is shaped to receive a portion of the end of the guide conduit for the cable. These guide channels are at both ends of the body axially aligned and extend along the intersection angle between the surfaces of the dihedral. The cover part of the housing has an extension as large as the body but is so shaped that its longitudinal edges fit over the edges of the body. At its ends, it is shaped in a manner similar to the ends of the body, also to receive a portion of the end a guide conduit. When the parts are assembled, the ends of said conduits are held fixedly between the body and the lid by appropriate means. For example, the body or the cover may have a projection or a key which fits into a notch in the end of the conduit before the cover is turned to hold the assembled parts. The lid further comprises guide channels curves for the cable so that when it exits of a pipe to an end of the assembly, it is (has) curved away from the rectilinear axis of the conduit this is followed by a curvature In the intermediate position of its length the cover has a perforated boss extending outwardly, in axial alignment with the apertured hub of the body and inwardly, the bore of the hub opens into a cavity for receiving a toothed pinion mounted on the spindle and with which the bent portion The pin, whose axis lies the least in the plane bisecting the dihedral [...] between the surfaces carrying the device, is secured in the apertured hub of the body and is open to the outside to the well bore of the hub of the cover and on said outer section is mounted the hub of a handle crank of which the handle moves in the region between the surfaces forming a dihedral angle. According to another feature of the invention, also fix the ends of the conduits in the control device by protrusions or keys engaging notches, this method of connection can be used in couplings for connecting sections of guide ducts, especially where of such conduits are of square section. Such a coupling includes a channel member having a section to fit over or engaging the aligned ends abutting or adjacent to the channels to be coupled. At vicinity of each of its ends within the channel has a key conveniently shaped which is integral and projects inward. Each conduits to be coupled also includes an opening had a recess in the vicinity of the extremity. The arrangement is such that when the two ends of the ducts are juxtaposed and are then engaged by the channel member, the two wedges thereof enter the openings or recesses of the ends of the pipes to maintain the ends in the juxtaposed position suitable. To keep the parts in position, there is provided a cover that is fitted to the channel member to make contact with the surfaces of the conduits not covered by the latter. Suitable means are provided to keep it in position and these means may in some case be a number of projections and recesses penetrating into each other between the cover and the channel member. According to another feature of the invention and to increase the utility of control means according to the invention, means are provided for interconnecting two cables so that that which is actuated by the control device can transmit its movement to the other. For this purpose, such a means comprises two guides for the two cables, said cables being placed approximately parallel side by side, at least one of the two guides having curved portions to end in the other tangentially to cause in the open portion or recessed the helical projections of a cable engaged with the helical projections of the other cable. By this means, axial movements given to a cable are transmitted to the other cable. The invention will be described in more detail below with reference to the accompanying drawings in which: Figure 1 is a schematic perspective view of a cable control device according to the invention, positioned and controlling a primary cable and a subordinate cable for the simultaneous control of two windows; Figure 2 is a front elevation of the device; Fig. B is a section plane of fig. 2; Figure 4 is an elevation of the body of said device; Figure 5 is a similar view of the cover thereof; Figure 6 is a cut with the line VI-VI of fig. 5; Fig. 7 is a perspective view of a set of elements that form a means of conduit coupling according to the invention; Figure 8 is a cross-sectional view to a larger scale of the joint connection; Figure 9 is a view in front elevation, with the cover removed, of a cable connection; Fragment Fig. 10 is a view of a portion of one of the elements represented in Figure 9; Fig. 11 is a cross-sectional view by the central portion of Figure 9 in an enlarged scale and with the cover in position. In the particular mode for practicing the invention Figures 1 to 6, the device has a symmetrical shape both longitudinally and laterally. Furthermore, it has a greater depth at the centre, depth decreasing regularly toward both ends. The device comprises a body 12, the interior of which is represented in Figure 4, which has two outer faces rear portions 13 and 14, in planes which are at right angles to each other, to fit, as shown to the fig. 1 to 3, in a angular location at right angles between two surfaces 15 and 16. Inside, it has two surfaces 17 and 18, also at right angles to each other, parallel to the outer surfaces 13 and 14, to leave to the walls the suitable thickness, extending through the other, one of them has a countersunk hole 19 for the fastening screws for mounting the device in position, for example on the surface 15. In a position intermediate between its ends, the body 12 within a boss 20 which is integral with a hole 21 in which is fixedly mounted a pin whose axis 22 projects forward along the plane bisecting the dihedral angle between the surfaces 13 and 14 and at right angles to what can be considered as the vertical axis of the device. The cover also has small threaded bosses 23 for receiving screws for fixing the cover which will be described below. The cover (the interior of which is represented in Figure 5) has a profile similar to the base and a development equal both longitudinal and lateral. In its central portion and coaxial with the hole 21, it comprises a boss 24, with opening, outwardly directed to receive the stepped portion 25 of the hub 26 of a crank handle 27 rotatably mounted on the outer end of the pin 22 by means of a screw whose shank 28 engages in a groove 29 in the spindle to prevent the handle to be removed from the spindle but for the freely rotating thereon. The lid includes a planar surface extending from one end to the other which is in contact with and fits over the planar surface 17 of the body. II also includes another smooth planar surface 31 extending from one end to the other which fits over the planar surface 18 of the body and further comprises two grooves or channels 32 and 33 recessed limited to the outside by surfaces 34 and 35 which are in the same plane as the surface 31 such that the surfaces 34 and 35 are also adaptable on the surface 18 of the base. The grooves or channels 32 define a guide for the portion of the cable passing through the device so that the intermediate portion thereof is brought on one side of the boss 20 of the body or it is held in mesh with the teeth of a suitable worm 36 rotatably mounted on the spindle 22 and whose teeth cooperate with the helical protuberances formed on the cable. The wheel is connected, by a torque coupling elastic 37 of any conventional design, with the handle 27 so that by rotation of the handle in either direction the wheel or worm rotates in the same direction. The cover is fastened to the body by countersunk head screws 38 which pass through the front part of the cover to be threaded into threaded holes in the small bosses 23 of the body. The conduits for the device represented in the drawing are of square section and each end of the body and the lid is shaped to fit on two sides of the conduit. For this purpose, the body is provided with recessed step portions 39 on both surfaces 17 and 18 terminating by steps 40 against which the ends of the conduits abut. The ends of the conduits are similar to that shown in the upper part of fig. 7 where the channel 41 has notches 42 in two ridges arranged diagonally, at a desired distance from the end of the conduit. Each end recessed 39 of the body 12 has a key or projection 43 to engage a notch 42 such that when the cover, which has recesses 44 similar stepped at its ends is carried ' in position, the two pipes, are provided at the top the other to the base, are held firmly attached to the device. Figure 1 is a schematic of the apparatus is 45 wherein the device is in position with a lower conduit portion 46 which fits snugly in the angle of the dihedron between the surfaces 15 and 16 and a portion of upper duct 47 arranged similarly. It will be appreciated that this mounting method of the device and placing the conduit sections is clearly and suitable. As will be appreciated, the cable with the helical projection at its periphery can be used to actuate all suitable devices from the controller 45, for example for opening and closing a single window. A Fig. 1 but is otherwise represented associated with two windows, one thereof being actuated by the cable from the device 45 while the other is operated by a cable engaged with the first mentioned cable. For this purpose the conduit 48 wherein the main cable 49 from the device 45 is slid and which is connected to the window 50, is associated with another conduit 51 in which an auxiliary cable is slid. The two cables are interconnected by a connection device, cable 52, diagrammatically indicated in Figure 1 and represented in details in fig. 9,10 and 11. It comprises a covered elongate rectangular housing 53, the [...] being fastened by screws 54. The housing 53 has two guides into channels 55 and 56 for cables that are parallel and spaced apart from each other by partition walls 57 in the vicinity of the ends of the housing but, in the central portion curve toward each other and intersect according to a desired degree. In a guide 55, to which the guide conduits 47 and 48 are connected, the cable slides 49. In the other guide 56 is mounted the auxiliary cable 58, it slides in the conduit 51 and is connected to the window 59. The degree of intersection of the channels 55 and 56 of the central portion of the casing is such that the helices projecting 60 of the cable 49 mesh with the projecting propellers 61 of the auxiliary wire 58.
