Abstract
A coupling pin (10) comprising a carriage member (12) and a riding member (14) longitudinally slidable over the carriage member. The carriage member and riding member being mutually inclined longitudinally, and together complementing each other to form a uniform pin. The pin may be inserted into an aperture such that the carriage member is first disposed therein, and a force subsequently applied to the riding member causing it to move longitudinally with respect to the carriage member, into a load-bearing position.
Claims25
A coupling pin for fastening together multiple sections, said pin comprising:
- a carriage member;
- and
- a riding member, longitudinally slidable over said carriage member,
- said carriage member and said riding member being mutually inclined longitudinally, and together complimenting each other to form a uniform pin,
- wherein at least one of said carriage member and said riding member comprises:
- (i) a front support ring, adapted for positioning and securing said riding member to said carriage member;
- and
- (ii) a rear support ring, adapted for positioning and securing said riding member to said carriage member, and
- wherein said pin is configured to be inserted into an aperture through said sections, said pin is configured to be displaced into a load-bearing position by an external axial force applied at one end of said riding member, whereby said carriage member substantially overlaps said riding member, and said pin is configured to be displaced into an insertion/retraction position by an opposite external axial force applied at the other end of said riding member, whereby said carriage member is axially shifted with respect to said riding member.
A method for insertion of a pin into an aperture through multiple sections, the method comprising the following steps:
- a) providing a pin comprising a carriage member and a riding member longitudinally slidable over said carriage member, said carriage member and said riding member being mutually inclined longitudinally, and together complimenting each other to form a uniform pin, wherein at least one of said carriage member and said riding member comprises:
- (i) a front support ring, adapted for positioning and securing said riding member to said carriage member;
- and (ii) a rear support ring, adapted for positioning and securing said riding member to said carriage member, the pin being displaced into a load-bearing position by an external axial force applied at one end of said riding member, whereby said carriage member substantially overlaps said riding member, and said pin being displaced into an insertion/retraction position by an opposite external axial force applied at the other end of said riding member, whereby said carriage member is axially shifted with respect to said riding member;
- b) inserting the pin in the insertion/retraction position into said aperture, such that said carriage member is disposed in said aperture;
- and
- c) applying an external axial force to said riding member such that said riding member is displaced longitudinally with respect to the carriage member, into said load-bearing position.
