Definitions

  • This invention relates to door checks particularly, but not exclusively, door checks intended for use on the doors of motor vehicles.
  • one current test procedure consists of subjecting an unlubricated mechanism to 100,000 operations with the mechanism periodically dusted with desert soil.
  • GB-A-1 597 747 shows a not dissimilar arrangement.
  • GB-A-1 449 671 instead of a torsion bar a coiled bar is employed, with the movable roller mounted on one free end of the bar.
  • the present invention is aimed at reducing the relative tilting of the rollers.
  • GB-A-795867 discloses a door check in which a pair of rollers are mounted in a bracket and are spring biassed towards the check arm extending between the rollers by a spring bar of U-shape, the rollers being rotatably carried by short parallel legs of the bar.
  • the free ends of the legs are slidably guided in respective guide slots in the bracket, positioned closely adjacent to the rollers, the slots extending in the direction of separation of the rollers. Such slots would not appear to inhibit tilting of the spring bar legs in use.
  • a door check comprises a contoured check arm adapted to be pivotally secured to a door or door pillar, and a bracket adapted to be secured to a door pillar or door respectively, first and second rollers mounted on or in the bracket with the check arm extending between the rollers, a spring bar carried by the bracket and providing a spring force to bias the rollers relatively towards each other, the spring bar comprising a leg on a portion of which the first roller is mounted, one end of the leg being continuous with one end of a bent portion of the bar, characterised in that the opposite, free end of the leg is restrained to the bracket against movement in the direction of separation of the rollers which the spring force in the bar would otherwise produce, said portion of the leg on which the first roller is mounted is spaced substantially from the restrained free end, and the other end of the bent portion opposite to said one end of the bent portion is restrained directly or indirectly to the bracket against movement in the direction of separation of the rollers which the spring force in the bar would otherwise produce, the restraints on the bar
  • the free end of the leg may be restrained by being clamped to the bracket it is preferred that the free end is pivotally supported on the bracket.
  • the free end of the leg is preferably provided with a recess in one side which engages with the bracket to provide a fulcrum for the pivoting, and to locate the free end.
  • the bent portion of the bar may be arranged to act as a torsion bar, or it may be arranged to be subjected to bending stresses only, or a combination of torsion and bending stresses may be employed.
  • the second roller is mounted on said other end of the bent portion of the bar.
  • said other end is held directly against lateral movement relative to the bracket urged by the spring force, so that only the first roller is displaced relative to the bracket on movement of the check arm.
  • both rollers are displaceable relative to the bracket, and said other end of the bent portion is continuous with a second leg of the bar on which the second roller is mounted, and the free end of the leg is restrained to the bracket against movement in the direction of separation of the rollers which the spring force in the bar would otherwise produce.
  • the bracket is conveniently formed from sheet material that is bent into an angular S-shape, the rollers are held captive between two of the horizontal limbs of the S, and the free end of the or each leg is pivoted on the third horizontal limb of the S.
  • the first check illustrated comprises a bracket 11 formed from a rectangular strip of sheet material by bending about five transverse lines so as to be substantially of angular S-shape, as shown in Figure 2, comprising three parallel, horizontally extending walls 2, 3, and 4, and vertical walls 5 and 6 for connection by screws engaging holes 7 to a door or door pillar.
  • the walls 2 and 3 of the bracket are connected by a further vertical wall 8 which is apertured at 11 to receive a contoured horizontal check arm 9 provided with a pivot hole 10 for attachment to a door pillar or door respectively.
  • bracket 1 is shown mounted in a vehicle door, with the pivot 10 secured to a further bracket 10' mounted on a door post.
  • the hinge axis of the door is indicated at X.
  • First and second plain cylindrical rollers 12 and 13 respectively are mounted on a spring bar 14 and vertically between the bracket walls 2, 3.
  • the spring bar comprises parallel vertical legs 15 and 16, and a bent portion 17 which inter-connects the legs 15, 16.
  • Leg 15 is substantially longer than leg 16 and extends through a hole 18 provided in lower wall 4 with which it has a pivotal abutment to restrain it against lateral movement.
  • leg 15 In order to locate the free end 19 of leg 15 against vertical movement relative to wall 4, the end 19 is provided with a recess 20 on the side remote from leg 16 which receives the edge of the material of wall 4, and the recess 20 thereby acts as a fulcrum for pivotal movement of the lower part of leg 15.
  • Notch 20 is produced by local flattening of the bar.
  • Leg 15 extends through respective aligned open-ended slots 21, Figure 1, in the walls 2, 3, the slots extending in the direction away from leg 16 to enable the first roller 12 to move laterally of the bracket 1.
  • the shorter leg 16 extends through aligned holes 22 in the walls 2, 3, and the leg 16 and second roller 13 are thereby held against lateral movement relative to the bracket 1.
  • the bent portion 17 of the bar 14 comprises a horizontally extending substantially U-shaped part 23 extending substantially perpendicularly to the walls 5, 6, that is generally in the direction of movement of the check arm 9, and a pair of right-angle bend parts 24, Figure 2, which connects the limbs of the U respectively to the upper ends of the legs 15, 16.
  • the limbs of the U-shaped part 24 converge slightly towards their free ends.
  • Check arm 9 is contoured in the usual way to provide two hold-open positions of the door in use. Movement of the check arm between the rollers 12, 13 causes first roller 12 to be deflected away from roller 13 against the spring force exerted by bar 14. Displacement of the roller 12 away from roller 13 is accommodated by a relative movement apart of bar parts 24 to open the U-shaped part 23, and by pivoting of leg 15 about free end 19.
  • Figures 7 to 9 show a second check, and corresponding reference numbers have been applied to parts corresponding to the check of Figure 1.
  • the check differs from that of Figure 1 only in the shape of the bent portion 17 of the bar 14, the right-angle parts 24 being omitted, so that the U-shaped part 23 extends vertically. This is useful in circumstances where space is limited.
  • Figure 10 shows a more significant departure from the arrangement of Figure 1 in that the legs 15, 16 are made of equal length, and the free ends 19, 19' of the legs both have pivotal abutments with the bracket lower wall 4.
  • the rollers 12, 13 are both capable of lateral movement relative to bracket, slots similar to slots 21 of Figure 1 being provided also for the leg 16 to accommodate the lateral movement of roller 13.
  • the arrangement of the bar 14 and rollers 12, 13 is entirely symmetrical in this arrangement.
  • Figure 11 shows a modified bar arrangement which may be used in a check similar to that of Figure 10.
  • the bent portion 17 is in the form of a coil.
  • check arm is not relevant to the invention and that many forms of check arm may instead be employed.
  • a laminated check arm may be employed where the rollers engage with the wider sides of the arm rather than with the narrow edges.
