Abstract
A sliding door assembly for a vehicle body has a first, slidable door hung from an upper slide rail, and this door may be swung from a closed position in a parallel plane with a second door to an open position. The first door is swung between open and closed positions by a hand-operated lever of a lever mechanism; the lever is rotatable about a pivot pin to actuate operating rods to pivot a carriage so that rollers on the carriage rest at 45.degree. to the horizontal when the first door is closed, with an upper part of the circumference of each roller being received in an elongate slot.

A sliding door assembly having at least one slidable door having means to be swung out of a first, closed position into a second position, said at least one slidable door being swingable out of a first, general plane occupied in said closed position to occupy whilst in said second position a second, general plane substantially paralled to said first, general plane;
- said slidable door having means to be slid past a wall or other door of said assembly which is aligned with said first, general plane and in which said at least one swingable door carries slider means, for example rollers, and said slider means is cooperable with a slide rail to allow said door to be slid along said slide rail in use, said slider means being arranged to pivot about said slide rail relative to said door when said door is swung from said first position relative to said second position;
- the slide rail defining a groove along which the slider means is entrained to move, said groove being appropriately dimensioned to allow the slider means to pivot whilst still in the groove, the inner edge of the groove being curved, the curved inner edge of the groove being defined by the curved edge of a projection of convex section.
A sliding door assembly having at least one slidable door having means to be swung out of a first, closed position into a second position, said at least one slidable door being swingable out of a first, general plane occupied in said closed position to occupy whilst in said second position a second, general plane substantially parallel to said first, general plane;
- said slidable door having means to be slid past a wall or other door of said assembly which is aligned with said first, general plane and in which said at least one swingable door carries slider means, for example rollers, and said slider means is cooperable with a slide rail to allow said door to be slid along said slide rail in use, said slider means being arranged to pivot about said slide rail relative to said door when said door is swung from said first position relative to said second position;
- the slider means being connected to a carriage which pivots with this slider means and said carriage being pivotally connected to at least one operating rod, said at least one operating rod being generally vertically reciprocable in use to pivot the carriage and the slider means, the or each operating rod being within the swingable door, the slider means and carriage also being a bell crank mechanism.
A sliding door assembly having at least one slidable door having means to be swung out of a first, closed position into a second position, said at least one slidable door being swingable out of a first, general plane occupied in said closed position to occupy whilst in said second position a second, general plane substantially parallel to said first, general plane;
- said slidable door having means to be slid past a wall or other door of said assembly which is aligned with said first, general plane and having a pivotable lever connected by a link mechanism to at least one operating rod, said at least one operating rod being cooperable with means on the at least one door to swing said door from the closed position into said second position, said link mechanism and said at least one rod being contained within the door and arranged so that said mechanism does not contact, cooperate with, or use for support a lower frame portion or rail adjacent the door during movement of the door from the closed position to the second position or vice versa.
A sliding door assembly having at least one slidable door having means to be swung out of a first, closed position into a second position, said at least one slidable door being swingable out of a first, general plane occupied in said closed position to occupy whilst in said second position a second, general plane substantially parallel to said first, general plane;
- said slidable door having means to be slid past a wall or other door of said assembly which is aligned with said first, general plane and in which said at least one swingable door carries slider means, for example rollers, and said slider means is cooperable with a slide rail to allow said door to be slid along said slide rail in use, said slider means being arranged to pivot about said slide rail relative to said door when said door is swung from said first position relative to said second position, and in which said slider means is connected to a carriage which pivots with this slider means and said carriage is pivotally connected to at least one operating rod, said at least one operating rod being generally vertically reciprocable in use to pivot said carriage and the slider means.
A vehicle body having a sliding door assembly having at least one slidable door having means to be swung out of a first, closed position into a second position, said at least one slidable door being swingable out of a first, general plane occupied in said closed position to occupy whilst in said second position a second, general plane substantially parallel to said first, general plane;
- said slidable door having means to be slid past a wall or other door of said assembly which is aligned with said first, general plane and in which said at least one swingable door carries slider means, for example rollers, and said slider means is cooperable with a slide rail to allow said door to be slid along said slide rail in use, said slider means being arranged to pivot about said slide rail relative to said door when said door is swung from said first position relative to said second position, and in which said slider means is connected to a carriage which pivots with this slider means and said carriage is pivotally connected to at least one operating rod being generally vertically reciprocable in use to pivot said carriage and the slider means.
A sliding door assembly having at least one slidable door having means to be swung out of a first, closed position into a second position, said at least one slidable door being swingable out of a first, general plane occupied in said closed position to occupy whilst in said second position a second, general plane substantially parallel to said first, general plane;
- said slidable door having means to be slid past a wall or other door of said assembly which is aligned with said first, general plane and having a pivotable lever connected by a link mechanism to at least one operating rod co-operable with means on the at least one door to swing said door from the closed position into said second position, the pivotable lever being arranged such that, in use, it becomes operatively disconnected when the door has been swung to the second position.
A lever mechanism comprising a support plate or support member having a recess housing a hand-operable pivotable lever, the lever being connected to one end of a link by a first pivot pin and the other end of the link being connected to a second pivot pin which passes through a slot in a wall of the recess, said second pin being constrained to move along the slot upon rotation of the pivotable lever about an axis provided by a third pivot pin, a connecting member being mounted between the first pin and third pivot pin, the arrangement being such that the lever may be rotated in a first direction from a first position within the recess about said axis until said second pin reaches the bottom of said slot, during which rotation the connecting member rotates about said axis, whereupon further rotation of the handle in said first direction results in the handle being operatively disconnected from the remainder of the lever mechanism by the lever being disconnected from said axis.
A sliding door assembly of the type specified in which the at least one swingable door is hung from a slide rail and carries slider means, for example rollers, which slider means is adjacent to an upper portion of said at least one swingable door and co-operable with said slide rail to allow said door to be slid along the slide rail in use, said slider means being arranged to pivot about the slide rail relative to said door when said door is swung from the first position relative to the second position, the slide rail defining a groove along which the slider means is entrained to move, said groove being appropriately dimensioned to allow the slider means to pivot whilst still in the groove and in which the width of the bottom of the groove conforms to the width of the slider means.
