Abstract:
1. A coupling device for releasably coupling tubes of a pole dancing pole, the coupling device comprising: a hollow body; a first mechanism within the hollow body, comprising a first threaded element and a first screw member configured to mate with the first threaded element, wherein the first mechanism is configured for applying a force against opposing interior surfaces of the hollow body, the opposing interior surfaces including a first interior surface of the hollow body, during turning the first screw member with respect to the first threaded element, the first mechanism thereby being configured to expand a portion of the hollow body for applying a force to a first interior surface of at least one of the tubes; and at least one fastener coupling the first threaded element to the first interior surface of the hollow body, the at least one fastener comprising: an inner portion fastening the at least one fastener to the first threaded element, and an outer portion coupling the at least one fastener to the first interior surface of the hollow body and configured to float relative to the first interior surface of the hollow body, the first mechanism thereby being configured to substantially maintain an alignment between a screw axis of the first threaded element and a screw axis of the first screw member during turning the first screw member with respect to the first threaded element, wherein the at least one fastener is located through a hole of the hollow body, the hole being sized for allowing the first threaded element to move with respect to the first interior surface of the hollow body.
