Definitions

  • This invention relates to door checks for vehicles of the kind in which an arm in the form of a strap adapted to be pivotally connected at one end to a door frame is withdrawn through a housing adapted to be mounted on a complementary part of the door against a restraining force applied to the strap by the frictional engagement with the strap of a restraining mechanism housed within the housing, the housing comprising a first component in the form of a metal base plate for attachment to the door, a second component in the form of a block provided with a cavity facing the base plate and in which the restraining mechanism is housed.
  • EP-A-0 338 888 describes a door check for vehicles of the kind set forth in which the housing comprises a base plate and a cover plate, the base plate having lugs which co-operate with the base plate to lock the base and cover together.
  • EP-A-0 418 783 describes a door check for a vehicle door of the kind set forth, having a cover plate adapted to be fixed to the door of a vehicle in order to house the restraining mechanism, the cover plate being moulded from a strong resin such as glass-reinforced nylon.
  • one of the components is of generally channel section having side flanges in which side edges of the other component are received, which side flanges are formed with axially spaced apertures, and opposite sides of the block are provided with lugs which are complementary to the apertures and are received within the apertures to define locking means which secure the two components together against separation.
  • the major portion of the housing is therefore constructed from plastics material which reduces weight without any significant loss of strength.
  • the block may comprise a one-piece plastics moulding which is cheap to produce in large quantities and in which tolerances can be maintained within close limits.
  • the side flanges may extend between opposite ends of the component.
  • the plate When the side flanges are provided in the metal plate, the plate may also be provided with end flanges which co-operate with the ends of the component of plastics material. This strengthens the housing and takes the loads applied to the component of plastics material from the restraining mechanism.
  • each flange may be formed with axially spaced apertures adapted to receive complementary lugs projecting from opposite sides of the block and which define the locking means as the flanges are deformed relatively towards each other to embrace opposite sides of the block.
  • the door checks are normally fitted after main paint treatment so that the door checks are not subjected to high oven temperatures, usually about 200°C. However they do have to pass through a paint repair system which entails the outer skins of the doors being low temperature heated with heat lamps. Thus the checks may be subjected to temperatures substantially of 65°C which should not cause differential expansion between the two different materials to take place to an extent sufficient to cause problems, specifically to overcome the effect of the locking means.
  • the first component is of generally channel section having side flanges in which side edges of the block are received in the channel, and the components are provided with external longitudinally extending undercut ribs which are juxta-posed when the block is received in the channel, each pair of ribs being received within a clip which defines the locking means.
  • any differential expansion between the materials of the components, with the block expanding to a greater extend than the metal, will be compensated for by flexure of the clip.
  • the clips are of spring steel and substantially of C section.
  • the ribs may extend between opposite ends of the components to receive one or more clips. When more than one clip is used, the clips are equally spaced along the length of the housing.
  • the ribs may comprise superimposed local projections with one clip co-operating with each superimposed pair of projections.
  • a vehicle door assembly is illustrated in Figure 1-14 of the accompanying drawings which shows a vehicle door 2 hingedly connected to a door frame 3 for movement about a substantially vertical axis between open and closed positions. Movement of the door 2 between the open and closed position is restrained by means of a door check comprising a housing 1 mounted on the inner side of a panel or skin of the door 2, and an arm or strap 4 which is pivotally connected at one end 5 to the door frame 3, and is adapted to be withdrawn in opposite directions through the housing against a force applied to it by the frictional co-operation with it of a restraining mechanism 7 housed within the housing 1.
  • the other end of the strap 4 carries a head 6 defining an abutment stop for engagement with the housing 1 to define the fully open position of the door.
  • the arm 4 slides through the housing 1 with the head 6 assuming an advanced position as shown in Figure 1 of the drawings.
  • the restraining mechanism 7 is illustrated in Figures 13 and 14 of the drawings and comprises a pair of rollers 13,14 which are urged by a spring 15 into frictional engagement with opposite sides of the arm 4.
  • the housing 1 comprises a metal base plate 10, and a block 11 of synthetic plastics material secured to the base plate 10 and provided with a cavity 12 which faces the base plate 10 and in the restraining mechanism 7 is housed.
  • the base plate 10 is of generally channel section having a generally planar base 16 of oblong rectangular outline and pairs of separate upstanding side and end flanges 17, and 18, respectively.
  • the end flanges 18 are normal to the plane of the base, but the side flanges 17 diverge, substantially at 15°, with respect to the base 16.
  • Each side flange 17 is provided with three axially spaced apertures 20.
  • a pair of axially spaced headed screw-threaded fixing studs 21 projecting from the base 16 in the opposite direction from the flanges 17 and 18 are adapted to receive nuts to secure the housing 1 to the inner skin of the door 2.
  • the block 11 comprises a one-piece plastics moulding having integral side and end walls between which the cavity 12 is defined. Each side wall is provided with three axially spaced outwardly projecting lugs 22 complementary to the apertures 20.
  • the restraining mechanism 7 is first fitted into the cavity 12 in the block 11, and the studs 21 are inserted through openings 10 the base plate 16 until their heads are flush with its inner face.
  • the block 11 is then inserted into the mouth of the channel, in the space defined between the side and end flanges 17 and 18.
  • the side flanges 17 are then deformed inwardly from the inclined position shown in Figure 5 and into an upright position with the apertures 20 receiving the complementary lugs 22 on the block 11.
  • the co-operation of the lugs 22 within the apertures 20 defines locking means for securing the metal base plate 10 and the block 11 of plastics material against separation and, at the same time, clamping the heads of the studs 21 firmly against the base plate 10.
  • the housing illustrated in Figures 15-17 of the drawings is particularly suitable for use in constructions in which the door check may be subjected to high temperatures, for example in the region of 95°C, and the construction is chosen to compensate for any consequent differential expansion of the materials of the metal base plate 10, and the block 11 of synthetic plastics material.
  • Distal portions of the flanges 17 of the base plate 10 are cranked downwardly to form undercut ribs 60, and the external walls of the block 11 are formed with oppositely directed undercut ribs 61.
  • the ribs 60,61 may be continuous and extend between opposite ends of the components to receive one or more clips, depending upon the size of the component and the required strength of the locking means. When more than one clip is used, the clips are equally spaced along the ribs 60,61.
  • the ribs may comprise superimposed discrete projections, with a separate clip co-operating with each superimposed pair of projections.
