Abstract
A foldable chair of the lawn chair type has ground-engaging front and rear legs, attached to and carrying a back frame and seat frame, the back frame and seat frame being pivotally attached to a spreader rod which extends beyond the back and seat frames to bear against one of the leg members when the chair is unfolded. A contact pad mounted on the extending portion of the spreader rod is formed as an externally-contoured bushing fit over the spreader rod and adapted to engage the leg member to restrict side-to-side movement of the spreader rod, with respect to the leg member, when the chair is unfolded.
Claims9
A foldable chair, comprising:
- a back frame and a seat frame, hingeably attached to a spreader rod, the spreader rod having ends protruding past the back frame and the seat frame;
- a front leg member and a rear leg member, carrying the back frame and the seat frame, the spreader rod also extending past at least one of the front leg member and the rear leg member, the spreader rod bearing transversely against said one of the front and rear leg members when the chair is unfolded;
- and,
- a contact pad mounted on each protruding end of the spreader rod and axially-fixed to the spreader rod, the contact pad being an externally contoured bushing, axially bored to fit over the spreader rod and having an external face shaped to engage said one of the leg members, the contact pad fixing the spreader rod against axial movement thereof over said at least one of the leg members, whereby the chair is secure when unfolded and said at least one of the leg members is protected from wear due to contact with the spreader rod.
In a foldable chair having supporting leg members and a spreader rod having ends extending across said leg members and swing straps pivotably connecting the leg members to the spreader rods at a point spaced from opposite ends of the spreader rod such that upon unfolding the chair, the ends of the spreader rod bear transversely against the leg members, the improvement comprising:
- a contact pad adapted to fit over said ends of the spreader rod, the contact pad having an external contour shaped to engage the leg member, the contact pad also having a slot for engaging the swing strap, the contact pad protecting the leg member from direct contact with the spreader rod and fixing the spreader rod against movement along its axis, transversely over the leg member.
