Abstract
A fastener for holding together two or more structures. The fastener includes a first bush and a second bush. The first bush includes a hollow shaft having a first end and a second end opposite to the first end. The first end of the first bush has a first radially-extending protrusion. The second bush includes a hollow shaft having a first end and a second end opposite to the first end. The first end of the second bush has a second radially-extending protrusion. The second end of the second bush is configured to connect to the second end of the first bush so as to resist separation of the first and second bushes and so as to define an axial hole through the fastener defined by the shaft of the first bush and the shaft of the second bush.
Claims19
A fastener for holding together two or more structures, the fastener comprising:
- a first bush comprising a hollow shaft having a first end and a second end opposite to the first end, wherein the first end of the shaft has a first radially-extending protrusion;
- and
- a second bush comprising a hollow shaft having a first end and a second end opposite to the first end, wherein the first end of the shaft has a second radially-extending protrusion and the second end is configured to connect to the second end of the first bush so as to resist separation of the first and second bushes and so as to define an axial hole through the fastener defined by the shaft of the first bush and the shaft of the second bush;
- wherein each of the first and second radially-extending protrusions has an inner surface that is oriented to face one of the structures held together by the fastener, and wherein one or both of the inner surface of the first radially-extending protrusion and the inner surface of the second radially-extending protrusion is part-spherical.
An assembly comprising:
- a first structure;
- a second structure;
- and
- a fastener extending through the first structure and the second structure and configured to resist separation of the first structure and the second structure;
- wherein the fastener comprises:
- a first part having a hollow shaft extending into a hole in a surface of the first structure and a radial protrusion disposed adjacent the surface of the first structure;
- a second part having a hollow shaft extending into a hole in a surface of the second structure and a radial protrusion adjacent the surface of the second structure;
- wherein the shaft of the second part is coaxial with the shaft of the first part, and is fixedly connected to the shaft of the first part to resist axial separation of the first part and the second part.
