Hook buckle device

A caster device is disclosed for movably supporting a load. The caster device includes a wheel for supporting the load and a wheel support having a first and a second extremity. The first extremity of the wheel support supports the wheel for rotation of the wheel about an axis of rotation. The second extremity of the wheel support defines an aperture and the wheel support has a first surface and a second surface. A support stem has a first and a second end, the support stem extending through the aperture such that the aperture is disposed between the first and the second end of the support stem. The second end of the support stem is connected to the load for supporting the load. Also, a leaf spring is disposed between the aperture and the second end of the support stem such that the leaf spring resiliently contacts the load and cushions the load relative to the wheel.

Caster device for movably supporting a load

A caster device for attachment to a first and a second member of a frame is disclosed, the members being disposed angularly relative to each other to define a corner of the frame. The members define apertures and attachment slots. The device includes a caster for supporting the frame and a top plate supported by the caster. The top plate has a first and a second edge, the second edge extending angularly away from the first edge. The first edge of the top plate extends along the first member of the frame. Also, the second edge of the top plate extends along the second member of the frame. A first wall has a first and a second end, the first wall extending from the first edge of the top plate. Additionally, the first wall is aligned with and extends along the first member. A second wall has a first and a second extremity, the second wall extending from the second edge of the top plate. The second wall is aligned with and extends along the second member. A first tab extends from the first wall, the first tab extending through one of the attachment slots of the first member. Also, a second tab extends from the second wall, the second tab extending through one of the attachment slots of the second member. The first and second tabs facilitate location of the caster device relative to the corner of the frame. Moreover, a first interlocking tab defines a first hook, the first interlocking tab extending from the first wall. The first interlocking tab extends through one of the attachment slots of the first member for interlocking the device to the frame and further supporting the frame. Additionally, a second interlocking tab defines a second hook, the second interlocking tab extending from the second wall. The second interlocking tab extends through one of the attachment slots of the second member for interlocking the device to the frame and further supporting the frame.

Caster device

The caster wheel assembly includes a top plate with downwardly extending walls which terminate in bottom flanges to support the frame of a heavy cabinet. The caster wheel assembly further includes side flanges with eyelets through which screws or bolts pass to threaded apertures in the frame of the heavy cabinet. The top plate is configured to bend elastically and then inelastically in response to a force on the caster wheels, thereby reducing the force transmitted to the cabinet frame.
