Abstract
Description
- This invention relates to door checks particularly, but not exclusively, door checks intended for use on the doors of motor vehicles.
- Vehicle manufacturers and Government bodies are devising increasingly stiff tests which door checks must survive in order to be considered suitable for use. For example, one current test procedure consists of subjecting an unlubricated mechanism to 100,000 operations with the mechanism periodically dusted with desert soil.
- Whilst there has been a multitude of previous proposals for doer checks most of them would not stand up to such arduous tests, or at least the modifications required to meet the tests would be prohibitively expensive.
- The major problem facing a door check designer is therefore to produce a check which will perform satisfactorily in use yet be inexpensive to manufacture.
- One relatively inexpensive door check arrangement was proposed in our U.K. Patent Specification No. 1247755 in which a contoured check arm extends between a pair of rollers mounted in a bracket, and one of the rollers is resiliently biassed towards the other roller by being mounted on one arm of a torsion bar.
- Whilst that arrangement has been very successful in practice there is now a requirement for a compact door check which is less costly to produce yet meets the current regulations.
- According to the invention 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 torsion bar carried by the bracket and comprising substantially parallel first and second legs on which are respectively journalled the first and second rollers, and a substantially U-shaped portion of the bar extending substantially in a plane which is normal to the axes of the legs, the opposite ends of the U-shaped portion being connected by respective angle portions of the bar to the adjacent ends of the respective legs, the arrangement being such that at least the first roller is capable of deflection relative to the bracket, and the bracket is provided with abutment means acting on the bar at or adjacent to the angle portion associated with the first leg to provide a fulcrum for pivotal movement of the first leg.
- The abutment means ensures that the torsion bar is constrained so that its operating characteristics are closely controlled. In the absence of such an abutment means the U-shaped portion of the bar would be subjected to bending stresses'in addition to torsional stresses, and this could lead to premature failure of the bar in certain circumstances.
- Since the second roller is mounted on the second leg of the bar it is unnecessary to provide a separate mounting pin for that roller, and this reduces the assembly costs.
- The abutment means preferably comprises a hook-shaped portion of the mounting bracket.
- The hook-shaped portion is preferably arranged also to retain the torsion bar against movement relative to the bracket in the axial direction of the legs.
- 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 hook-shaped portion is part of the third horizontal limb of the S.
- The second leg of the bar may be restrained to the bracket against lateral movement so that the second roller is held against lateral-movement, but if desired the second leg may be permitted to pivot in the manner of the first leg, a second abutment means being provided on the bracket to restrain the angle portion associated with the second leg.
- A door check for a vehicle in accordance with the invention will now be described, by way of example only, with reference to the accompanying drawings in which:-
- Figure 1 is a plan view of the check in the condition in which the door is closed;
- Figure 2 is a side elevation of the check looking in the direction of the arrow A in Figure 1, and without the check arm;
- Figure 3 is a rear view of the check looking in the direction of the arrow B in Figure 1, but for clarity omitting the check arm; and
- Figure 4 is an underplan view of a modified check shown mounted in a vehicle.
- The check comprises a bracket 1 formed from a rectangular strip of sheet metal 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 vertical walls engaging holes 7 to a door or door pillar. Thewalls 2 and 3 of the bracket 1 are connected by a further vertical wall 9 which is apertured at 10 to receive a contouredhorizontal check arm 11 provided with apivot hole 12 for attachment to a door pillar or door respectively. - First and second plain
cylindrical rollers second legs torsion bar 17 and are located vertically betweenbracket walls 2 and 3. The torsion bar further comprises aU-shaped portion 18 extending in a plane which is normal to the axes of thelegs bracket wall 4, theopposite ends U portion 18 being connected to the upper ends of therespective legs angle bend portions 21, 22. - The
portions 21, 22 are restrained to the bracket by respective abutment means on the bracket in the form ofrespective hooks hooks wall 4 and, as shown in Figures 2 and 3, the hooks are inclined at an angle of approximately 45° to the axes of thelegs torsion bar 17 against movement relative to the bracket in the direction of the axes of thelegs - The
first leg 15 extends throughslotted holes walls 3, 2 respectively to enable thefirst roller 13 to be deflected in the direction away from thesecond roller 14, thesecond leg 16 extending throughcorresponding round holes 27, 28 in thewalls 3, 2 respectively, to holdroller 14 against lateral movement. - In Figure 3 the
first leg 15 of the torsion bar is shown in full outline in the position it occupies when the rollers engage with the narrow portion of thecheck arm 11 as shown in Figure 1, and in dotted outline in the deflected position when the rollers engage with awide portion 29 of thecheck arm 11. It will be seen that thefirst leg 15 is pivotally deflected about a fulcrum point provided by thehook 23, by the action of the check arm on thefirst roller 13. Pivotal deflection of thearm 15 increases the torsional stress inlimb 30 of theU portion 18 of the bar. - The torsion bar is arranged to have a torsional pre-loading on assembly to the bracket 1. In its free state the lower ends of the
legs roller 13 towardsroller 14. - Since the
portions 21 of the bar are held against relative movement apart by thehooks U portion 18 of the. bar is not subjected to substantial bending stresses in use. - The
hook 23 controls the pivotal movement of thefirst leg 15 and this control assists in providing a consistent performance in use. This is in contrast to arrangements where the deflecting leg of a spring bar is provided on a relatively unrestrained loop or bend of the bar. - The axial spacing of
roller 13 from thehook 23 assists in minimising tilting of theroller 13 in use. - The
deflectable roller 13 is preferably arranged to engage with the smoother side of thearm 11, as shown, but the reverse would be possible. - As shown in Figure 1, the
wide portion 29 of thecheck arm 11 is provided with arecess 31 which is engaged by theroller 14 when the door reaches the fully open condition. However, therecess 31 is spaced fromstop faces 32 on the arm such that when theroller 14 is seated inrecess 31 thestop faces 32 are spaced slightly from the bracket wall 9. This enables the door to be pushed slightly beyond the normal open condition against resilient biassing of the rollers, to provide a cushioned action when the door opening movement is arrested by the check. - Figure 4 shows a modification of the check of Figures 1 to 3, in which parts corresponding to those of Figures 1 to 3 have been given corresponding reference numerals. For convenience of mounting the bracket 1 in a vehicle door of a particular shape the axes of the
rollers vertical walls - The slotted
holes slot 261 in wall 2 being shown. - In order to provide two hold-open positions of the door the
check arm 11 is provided with two spaced apartrecesses - A
mounting bracket 33 is secured to the vehicle body and is pivotally connected at 12 with thecheck arm 11 which carries a small stop pin engageable with the free end of thebracket 33 to restrict the pivotal movement of the check arm relative to thebracket 33. - In a further modification, not shown, the
second roller 14 andleg 16 are permitted to deflect in an identical manner to thefirst roller 13 andleg 15.
