Replaceable wheel or foot assembly and leg system for a sign display stand
11673426 · 2023-06-13 · ·

A wheel/foot assembly for a sign display stand or other object includes a cradle partially enclosing an optional wheel. The assembly is releasably attachable to a leg for a sign display stand, protects the leg and can be easily replaced if worn. The assembly protects wear on the stand and permits the sign display stand to be wheeled, rather than dragged or carried. Because the assembly is releasably attached, it can be replaced easily if damaged or worn.

Carrier device capable of varying contact damping with pressured displacement
20170334258 · 2017-11-23 ·

The present invention provides one or more carrier devices capable of varying contact damping with pressured displacement. The device is configured to be installed on mechanical force-receiving structures that have rolling wheels, rolling balls or slidably displaceable terminal block structure, carrying devices and transportation devices for humans or objects. When receiving pressure smaller than a set value, the device provides low contact damping and is thus easy to move. On the other hand, when receiving pressure greater than the set value, it provides high contact damping so as to prevent slip and thereby ensure safe placement.

In addition, when receiving pressure smaller than the set value, the device has its pre-stressed structure generate modulation to displacement corresponding to the size of the pressure it receives for the purpose of shock absorbency.
