A collapsible bin comprising a generally rectangular bottom wall and four side walls is provided. The bottom wall has an upstanding U-shaped support element at each corner thereof. The side walls are arranged into first and second pairs. Each pair of side walls is pivotally mounted and supported by the U-shaped support elements. The side walls are collapsible from an upright position to a position on the bottom wall to provide a storage configuration of relatively small size. Latch means are provided to secure the side walls in an upright position.
A collapsible flatrack assembly has a counterbalancing system whereby a normally upright post, pivotable relative to a horizontal base, is movable relative to the base under the action of a biasing force towards the upright position. The counterbalance includes a bar spring and a coacting follower which engages with the spring during movement of the post to deflect the spring.
A collapsible container with four side panels (15,16,17,18) all permanently connected to a base (1) by links (11,41) allowing the panels (15,16,17,18) to be moved between an upstanding condition on the base (1) where they are retained by engagement of bottom panel flanges (40) with channels (13,14) on the base (1) and can be coupled by coupling means (19,23) releasably secured by securing means (21,22) thereby to form an enclosure and allowing the container to be collapsed by folding down the panels (15,16,17,18) into an overlying relationship.
A container having a base portion including four vertical square tube members with one tube member at each corner of the base portion, and bottom surfaces of the base portion sloping inwardly to an elongated opening along the bottom of the base portion that is closed off by a trap door. The upper portion of the container is formed with four additional vertical square tube members that provide support for the upper sides of the container, with the upper square tube members and sides of the container being pinned to the lower vertical square tube members such that the four sides of the container can be folded downwardly onto the base portion when the container is emptied. When folded to an upright position the four upper sides interlock and are held in position by pressure from within the container.
A collapsible container has a base and a number of panels which are pivotally mounted to the base. When the container is being stored, the panels lie beside the base or upon the base, one on top of the other. When the container is in use, the panels are upright and define an enclosure. A latch is provided for interlocking adjacent panels. The latch has a slider which is slidable vertically when the container is upstanding and which slides between latch-locking and latch-unlocking positions. The latch further has a catch which is movable horizontally when the container is upstanding and which moves from a locking position for locking adjacent panels to an unlocking position. The latch has means for converting vertical movement of the slider to horizontal movement of the catch.
A collapsible container with four side panels (15, 16, 17, 18) all at least semi-permanently connected to a base (10) by links (11, 41) allowing the panels (15, 16, 17, 18) to be moved between an upstanding condition on the base (1) where they are retained by engagement of bottom panel flanges (40) with channels (13, 14) on the base (10) and can be coupled by coupling means (19, 23) releasably secured by securing means (21, 22) to a collapsed condition by folding down the pannels (15, 16, 17, 18) into an overlying relationship. The link means (FIGS. 4-6) allowing the panels to move normally to their plane to disengage the flanges with the channels and then to pivot inwards to a horizontal position.
