ABSTRACT:
A resilient bearing support is provided for suitcase rollers and the like. A single part made of resilient material is configured to rotatably support travel rollers in a lower fork-like projection. The tip of this part is connected to a lower corner of a frame of a suitcase. To facilitate desired shock absorbing characteristics, the part is provided with a transversely extending triangular opening. The shortest side of this opening is bounded by a thin wall section that is curved outwardly to accommodate flexure of this wall during compression of the part. The other two sides of the triangular opening are curved inwardly to roll on one another to increase the resistance of the bearing part to compression in response to increasing loads.
