US 2024/0401362 A1 · RESILIENT SLIP FRICTION JOINT

Abstract

A slip connector to connect first and second members of a structure to allow relative but resisted movement, and to at least in part return any movement. In one embodiment, the connector includes a first and second components and a resilient fixing. The resilient fixing holds mutually slidable ramped surfaces of the first and second components contiguous so that the line(s) of action of the fixing(s) is/are oblique to the mutually slidable ramped surfaces held contiguous. In another embodiment the connector includes first, second and third components and a resilient fixing. The resilient fixing holds mutually slidable ramped surfaces of the first and third components contiguous and mutually slidable ramped surfaces of the second and third components contiguous so that the line(s) of action of the fixing(s) is/are oblique to the mutually slidable ramped surfaces held contiguous.

Dependent claims

A self-centring slip connector connecting first and second members so as to allow relative but resisted movement between the first and second members from an initial position due to an external force, and also fully return the first and second members back to the initial position, the connector comprising:

a first component connected to said first member, the first component having a ramped surface;
a second component connected to said second member, the second component having a ramped surface;
and
a resilient fixing providing a compression force in a direction to hold the ramped surface of the first component in contiguous relation with the ramped surface of the second component;
wherein, under the external force, the ramped surfaces of the first and second components slidingly move relative to each other in a first direction oblique to the direction of the compression force, and wherein upon a ceasing of the external force to zero, the first and second members return to the initial position.

a) a first component connected to said first member, the first component having a ramped surface;
b) a second component, the second component having a ramped surface;
c) a third component having a ramped surface over lapping or under lapping with at least a part of the ramped surface of the first component and at least a part of the ramped surface of the second component, at least one of the second component and the third component connected to said second member;
d) a resilient fixing providing a compression force in a direction to hold at least the part of the ramped surface of the first component in contiguous relation with the ramped surface of the third component, and to hold at least the part of the ramped surface of the second component in contiguous relation with the ramped surface of the third component;
wherein, under the external force, the ramped surface of the first component and the ramped surface of the third component and the ramped surface of the second component and the ramped surface of the third component slidingly move relative to each other in a first direction oblique to the direction of the compression force, and wherein upon a ceasing of the external force to zero, the first and second members return to the initial position.
