Definitions

  • the present invention relates to the field of assembling and holding frames and other elements to be held by clamping during their final assembly, generally by bonding, and relates to a device for clamping and holding elements to be assembled by gluing, stapling, nailing or riveting (see for example DE-C 181 133).
  • the present invention aims to overcome these drawbacks.
  • a device for clamping and holding elements to be assembled, by gluing, stapling, nailing, or riveting constituted by a ribbon wound at one end on a spool and fixed at its other end on an operating axis, the assembly being mounted in a protective casing, and by recovery and positioning parts at the corners, characterized in that the operating axis is a disengageable axis surmounted by an operating button which can be moved over said axis, and being able to be locked in various displacement positions on this axis, this operating button being provided, moreover, with a toothed pinion which can cooperate, in a position of displacement of the button, with a pinion integral with the axis slit from the ribbon winding reel, and in another position for moving the button, with a spring loaded ratchet, the ribbon wound on the reel crossing the operating axis which is slit for this purpose, so as to fo make a loop coming out of the housing.
  • the device for clamping and holding elements to be assembled which essentially consists of a tape 1 wound at one end on a spool 2 and fixed at its other end to an operating shaft 3, the assembly being mounted in a protective casing 4, and by parts 5 for recovery and positioning at the corners, and characterized in that the operating axis 3 is in the form of a disengageable axis on which is mounted, in a displaceable manner, an operating button 6 which can be locked in various displacement positions on the axis 3.
  • the operating button 6 is also provided with a toothed pinion 7 which can cooperate, on the one hand, in a position of displacement of the button, with a pinion 8 integral with the split axis 9 of the reel 2 for winding the ribbon 1, and, on the other hand, in another position for moving button 6, with a click quet 10 loaded by a spring 11.
  • the ribbon 1, wound on the reel 2 crosses the operating shaft 3, which has, for this purpose, a slot 12, so as to form a loop 14 leaving the casing 4 .
  • the split axes 3 and 9, for maneuvering and for the spool 2, are guided in rotation between two walls of the casing 4, which simultaneously maintain the spool 2 and guide the ribbon 1.
  • the operating pin 3 is provided at its end facing the operating button 6, on the one hand, with a male clutch means 13 cooperating with a female clutch means 13 ', of corresponding shape, and , on the other hand, above the means 13, in the direction of the button 6, of a hub 15 for guiding the latter, and the pawl 10 is mounted on the wall of the casing 4 on the side of the means 13 of the axis 3.
  • the pinion 8 of the axis 9 of the coil 2 advantageously extends above the pawl 10 with a spacing from the latter at least equal to 1 thickness of the pinion 7 of the button 6, and the latter is either loaded by a spring tending to maintain it in one of its extreme positions on the hub 15 of the axis 3, or provided with a stop means 16 in position on the hub 15, in each intermediate position of displacement on the axis 3, such as a spring loaded ball catch, or the like.
  • This embodiment allows, in the case of a button 6 loaded by spring in one of its directions of movement, to know with certainty in which position is the pinion 7 of the button 6, namely, meshing with the pinion 8 of the axis 9 or with the pawl 10, an intermediate position between these two allowing the release of the coil 2 simultaneously with that of the axis 3, and, in the case of a button 6 provided with a stop means 16 in position on the hub 15, to ensure the exact positioning of the button 6 in each extreme and intermediate position.
  • the strands of the loop 14 leaving the casing 4 are guided between a spacer element 17, forming part of the casing 4 and simultaneously forming a recovery and positioning angle for a corner of the elements to be assembled, and two cylinders 18 solidai res of the casing 4, such that each strand passes between a cylinder 18 and the element 17, and, at the outlet of the strands of the loop 14, the casing 4 is further provided with a multiple imprint 19 consisting in several segments of different inclination relative to the face of the casing and allowing the support of elements to abut at various angles.
  • the multiple imprint 19, as well as the parts 5 for taking up and positioning at the corners, are advantageously provided with at least one edge for guiding the ribbon 1, the parts 5 being able to be provided, in addition, with a vertical elastic segment 20 intended to grip the ribbon 1.
  • the device according to the invention operates in the following manner:
  • the ribbon 1 can be unwound from the reel 2 through the slot 12 of the operating shaft 3 so as to allow opening of the loop 14 sufficient to ensure mounting around the elements to be assembled, for example to form a frame.
  • the parts 5 are then threaded by their vertical segment 20 onto the ribbon 1 and placed at the corners of the frame, or the like, to be produced, and the button 6 is moved to an extreme position in which its toothed pinion 7 is in contact with the pinion 8 of the axis 9 of the reel 2.
  • the ribbon 1 is then rewound on the reel 2 until a low tension is obtained, then the button 6 is moved on the hub 15 of the axis 3 in order to bring its female clutch 13 'in shape cooperation with the male clutch 13 of said axis 3.
  • the final tightening of the elements to be assembled is carried out, by simultaneous advance of the two strands of the ribbon, this tightening being maintained by locking the axis 3, by cooperation of the pawl 10 with the toothed pinion 7 of the button 6.
  • the ribbon 1 one end of which is fixed to the a xe of maneuver 3 and which also crosses the slot 12 of the latter, is wound, simultaneously with the end fixed to the axis 3, on the latter, so that the loop 14 formed outside the casing is stretched simultaneously and equally, by its two strands penetrating into the casing 4.
  • the part of the ribbon 1 extending between the coil 2 and the axis 3 can be wound, then, freely around the axis 3, because the axis 9 of the coil 2 is no longer loaded in any way.
  • the device described above has been more particularly as a device for tightening elements to be assembled, however, it is also usable, in a simple and rational manner, as a tightening strap.
  • this device it is possible to produce a device making it possible to hold and tighten elements to be assembled together, while ensuring, during tightening, a good distribution of the tightening force by simultaneous advance of the two strands of the loop enclosing said elements to be assembled.
  • this device is of particularly simple constitution and has a minimum of operating parts, so that its reliability is increased compared to known devices of this type.
