Abstract:
1. A caster device for attachment to a first and a second member of a frame, the members being disposed angularly relative to each other to define a corner of the frame, the members including apertures and attachment slots, said caster device comprising: a top plate having a first and a second edge, said second edge extending angularly away from said first edge, said first edge of said top plate extending along the first member of the frame, said second edge of said top plate extending along the second member of the frame; a first wall having a first and a second end, said first wall extending from said first edge of said top plate, said first wall being aligned with and extending along the first member; a second wall having a first and a second extremity, said second wall extending from said second edge of said top plate, said second wall being aligned with and extending along the second member; a further wall having a first and a second boundary, said further wall extending from said top plate and being disposed between the first and second members such that said top plate is disposed between said walls; a first interlocking tab which defines a first hook, said first interlocking tab extending from said first wall and extending through one of the attachment slots of the first member for interlocking said device to the frame and further supporting the frame; and a second interlocking tab which defines a second hook, said second interlocking tab extending from said second wall extending through one of the attachment slots of the second member for interlocking said device to the frame and further supporting the frame; wherein said hooks reinforce a connection between said caster device and the frame so that dislodgement of said caster device form the frame is inhibited, and wherein said first hook, when located within the respective slot, locks said first interlocking tab relative to the first member, and said second hook, when located within the respective slot, locks said second interlocking tab relative to the second member, the arrangement being structured such that said first and second hooks are initially located within their respective slots and are then moved into interlocking engagement with such slots, such that when located in interlocking engagement, at least a portion of said first interlocking tab extends in a direction beyond the associated attachment slot so as to be located along a portion of the first member, and at least a portion of said second interlocking tab extends in a direction beyond the associated attachment slot so as to be located along a portion of the second member, thereby locking said interlocking tabs to the members to inhibit the dislodgement thereof.
