Definitions

  • the present invention relates to a device for fixing a guide shoe on the lower part of a sliding door, in particular to an elevator door, and more particularly relates to a fixing device which allows easy assembly and disassembly and fast skates whenever it needs to be replaced.
  • FIGS. 1 and 2 respectively represent a perspective view of a pad fixing device currently in use, and a skate shown alone.
  • the shoe 10 is constituted by a parallelepipedal block of deformable material, for example rubber, which has on its end faces two grooves 12,14 each defining in the corresponding face two lips 16,18.
  • the device of FIG. 1 comprises a removable plate 20 which is fixed to the lower part of a door panel 22 by means of screws 24.
  • This plate has a cutout 26 of substantially T shape, comprising a rectangular upper recess 28 of length and height respectively equal to or slightly greater than those, L and H, of the shoe 10, and a lower rectangular recess 30 of length substantially equal to the distance which separates the bottoms of the grooves 12, 14 of the shoe.
  • a cutout 26 of substantially T shape comprising a rectangular upper recess 28 of length and height respectively equal to or slightly greater than those, L and H, of the shoe 10, and a lower rectangular recess 30 of length substantially equal to the distance which separates the bottoms of the grooves 12, 14 of the shoe.
  • At the upper part of the lower recess 30 protrude inwards two lugs 32,34.
  • the height of the lower recess 30, under the lugs, is slightly less than that of the shoe.
  • this pad is carried out on site, without dismantling the plate which serves as its support.
  • the pad 10 is first introduced into the upper recess 28, the grooves 12, 14 being placed astride the pins 32, 34.
  • the shoe is then forced to pass through the constriction formed by the pins and to pass into the lower recess 30. In this movement, the bottoms of the grooves are elastically deformed as they slide on the pins. This movement is favored by the fact that the pins have beveled surfaces 36 on their upper edge. In the final position shown in FIG.
  • the shoe is received in the lower recess where, due to the relative dimensions specified above, it is firmly held in position: in fact, it cannot move nor vertically, since it is in abutment at the top, against the lugs, and at the bottom, against the lower edge 31 of the lower recess 30, nor horizontally in the plane of the plate 20 since the bottoms of grooves are in abutment against the vertical edges of the '' lower recess.
  • the shoe is immobilized transversely to the plane of the plate thanks to the lips 16,18 which frame the vertical edges of the lower recess 30.
  • the present invention aims to remedy these drawbacks and relates to a pad fixing device which allows easy replacement of the pads, without having to dismantle any element of the door panel.
  • the backing pad is constituted by a bent profiled part comprising a horizontal branch which has a longitudinal groove in which comes to fit the horizontal edge of the upper recess, and a vertical branch whose the lower edge rests on the upper face of the pad.
  • the hooking means comprise a tongue extending downwards the vertical branch of the backing pad, and intended to penetrate into a slot of the same width drilled in the pad, said tongue being provided with at least two lateral teeth cut so as to penetrate unimpeded into the slot, but which catch on the slot wall when you want to extract the backing pad from the pad.
  • the slot has an oblong section equal to that of the tongue, but slightly less than the latter at the level of the teeth, each of the teeth having a chamfer on its entry edge and a shoulder on its exit edge.
  • FIGS. 3 to 5 having certain points in common with that of FIGS. 1 and 2, already described, only the new elements will be described below in detail.
  • a T-shaped cutout 50 comprising an upper recess 52 fully drilled through the front plate 44, and a lower recess 54 pierced through the double thickness of sheets of the edge 48. These two recesses are connected by shoulders 58.
  • a second difference between the device of the invention and that of the known technique described above resides in the fact that, as shown in FIG. 5, there are no longer pins at the level of the connection zone between the recesses 52 and 54, but the lateral edges 56 of the lower recess 54 are connected to the shoulders 58 by chamfers 60.
  • the pad 40 has a structure similar to that of the known pad of FIG. 2. In particular, it has at its ends two grooves 12,14 which each define two lips 16,18.
  • the relative dimensions of the shoe with respect to those of the recesses 52, 54 are exactly those given above with regard to the embodiment of FIGS. 1 and 2.
  • the shoe 40 is inserted in the lower recess 54, and the edge 48 provided with the shoe is slidably mounted in the groove 61 of a threshold profile 63.
  • a backing shoe 62 is used according to the invention.
  • This consists of a profiled part which comprises a horizontal branch 64 and a vertical branch 66, bent substantially at right angles to compared to the horizontal branch.
  • a groove 68 intended to fit the upper edge 70 of the upper recess.
  • the vertical branch 66 is flat and substantially rectangular and it extends downwards by a narrower hooking tongue 72, so as to determine on the lower edge of the vertical branch two shoulders 74.
  • the hooking tongue is provided with two lateral teeth 76 provided with chamfers 82 on their leading edge.
  • the attachment tongue is capable of being introduced inside a slot 78 pierced in the shoe and having a section equal to that of the tongue, above the teeth 76.
  • the pad 40 and the counter-pad 62 are assembled separately.
  • the hooking tongue 72 is pressed into skate slot 78.
  • the teeth 76 penetrate quite easily due to the elasticity of the pad and also from the provision of the chamfers 82.
  • the shoulders 74 are in abutment on the upper face of the pad.
  • the pad 40 is placed in the upper recess 52, which, as shown in FIG. 3, is accessible since it is entirely above the threshold profile. 63.
  • a cutout 80 is provided on the bent part 86 of the rear plate 46 so as not to hinder the positioning of the pad. Then pushes down on the branch 64 of the backing pad to pass the pad in the lower recess 54, until it abuts against the lower edge 86. Finally, by a slight pivoting movement exerted on the branch 64, combined with a crushing of the pad, the assembly is locked by fitting the groove 68 of the backing pad on the edge 70 of the upper recess.
  • the skate is thus blocked against any upward movement, as well as in the horizontal, longitudinal and transverse directions.
  • the device according to the invention therefore makes it possible to easily mount and dismount a shoe on an elevator door of the type not provided with a removable plate, while ensuring that the shoe is locked in its normal operating position.
  • the backing pad is both the means by which the pad is locked in position, and the pad positioning tool.
