Abstract: An improved base construction for a wheeled nestable shopping cart is provided by forming the base primarily from two U-shaped members. The first U-member has a planar portion disposed directly under the basket for supporting same, which portion terminates in downwardly directed rear legs which have the lower ends thereof joined to the rear wheel assemblies. The second U-member has the bight thereof forming the toe end of the base. The leg portions of this second member incline rearwardly and upwardly from the bight such that the free ends thereof are fixedly engaged with the rear legs adjacent the upper ends thereof. Side braces rigidly join the planar portion to the leg portions of the second member. This arrangement effectively prevents storage of goods on the base.

Abstract: A one piece T section used interchangeably as both a main T member and a cross T member in a supporting grid system for suspended ceilings. The interchangeable T sections have locking connectors engageable to interlock a pair of sections in end to end relation to form a main T splice with their tile supporting flanges substantially abutting. When the sections are used as cross T members, the locking connectors engage the web of a section used as a main T member and the flanges of the cross T sections overlie the flanges of the main T section with which they are interlocked.

Abstract: A first support member having a web with a slot and a pair of second support members having locking connectors insertable through the slot in side by side relation, each connector having a resiliently yieldable finger engageable against the web after insertion through the slot for interlocking the first and second members. Each connector has a laterally projecting detent on the side opposite the finger, an opening providing an arcuate generally vertical shoulder spaced rearwardly from the detent, and a laterally projecting spring retainer on the same side as the detent extending forwardly at least partially across the opening. When the connectors are inserted through the slot in side by side relation the forward end of each connector is confined against the other connector by the retainer thereof with its detent engaging the arcuate shoulder of the other connector, thereby interlocking the second support members, the retainers yielding resiliently to permit passage of the detents into the respective openings.

Abstract: A fire rated dry wall ceiling support system having fixed, aligned main beam members spliced together in a manner so as to absorb longitudinal compression, as for example resulting from thermal expansion during a fire. Each main beam includes a web surmounted by a bead with flange portions extending laterally outwardly from the web. Each web end includes a tongue extending axially outwardly for locking engagement with the adjacent beam member web and is so configured that the tongues fold in a longitudinal manner and become laterally displaced out of the normal plane of the tongues when the beam members are longitudinally compressed towards one another. Accordingly, the bead means become laterally displaced while moving towards one another in a longitudinal direction and may in fact overlap one another in a longitudinal sense. The system further includes support channels disposed transversely to the main beam members and engaged therewith.

Abstract: A gate construction for a shopping cart basket wherein a gate panel is disposed between sidewalls of the basket for closing an end thereof. The gate panel has its lower edge pivotally supported on a pair of brackets mounted to the sidewalls adjacent the lower corners thereof. A latch structure coacts between the sidewalls and the upper corners of the gate for holding the gate in a closed position. The pivotal mounting of the gate on the brackets permits the gate panel to be lifted upwardly to release the latch structure. The gate panel can then be swung outwardly and downwardly away from the basket into an intermediate open position. The support brackets are provided with substantially L-shaped slots in which the lower edge of the gate panel is pivotally and slidably supported, which slots have elongated horizontal portions disposed below and extending rearwardly along the bottom wall of the basket.

Abstract: A spring loaded compression strut adapted for mounting between the members of a suspended ceiling grid system and an overhead structural framework. The strut presses downwardly on the grid system so that the latter resists sudden upward movement as might be caused during an earthquake with the corresponding results that the integrity of the ceiling panel system is more adequately protected during such an event since the supporting grid members therefore are not subject to sudden, relative disorientation. The strut includes clip means at its upper and lower ends adapted for respective connection to the overhead structural framework and the grid members which enables the strut to be readily assembled with existing suspended ceiling systems since it is mounted in an external manner with respect to hanger wires found in such existing ceiling systems.

Abstract: A nestable shopping cart having a basket assembly supported on a wheeled base assembly which includes a rearwardly opening U-shaped base member having rearwardly projecting side rails. The side rails include diverging front rail portions which project rearwardly from the front end of the cart and terminate in rear rail portions which extend over a substantial length and terminate at the rearward end of the cart. The rear rail portions diverge outwardly with respect to the front rail portions and define a flared chutelike opening at the rearward end of the base member.The base assembly can also have a tray mounted thereon. The forward end of the tray has a cross rod, the ends of which project into openings formed in the opposite side rails for creating a hinged connection. The tray also includes rearwardly extending support rods which pass over a mounting member which extends transversely between the side rails and mounts thereon the front casters.

Abstract: A stabilizer strut extending transversely between grid members in a supporting grid system and the like. The strut includes a pair of leg portions disposed at right angles to one another with each end of the strut including a pair of aligned slot portions for engagement with an underlying grid member.
