US 6,862,905 B2 · Pin locking device and method of locking

Abstract

A locking device for locking one or more objects together includes a lock stud defined by an elongated shaft having a head at a first end and an annular recess at a second end, and a lock body that slides over and locks onto the second end. The lock body includes an outer housing having an aperture for receiving the second end of the elongated shaft. A cylinder lock mechanism is positioned in the outer housing, and the cylinder lock is rotatable between a locked and an unlocked position. The cylinder lock is rotationally coupled to a locking disc that is eccentrically disposed in the outer housing with respect to the aperture of the outer housing. The locking disc has an aperture therein that engages the annular recess in the elongated shaft when the cylinder lock is rotated to the locked position. The locking device also includes a sleeve that is dimensioned to slide over the elongated shaft to allow the locking device to be used for locking through several different sized apertures.

Dependent claims

A method of locking an end of a shaft to a locking mechanism, comprising:

providing a shaft with a locking position;
providing a locking mechanism dimensioned to receive a portion of a locking section of a shaft and having a first aperture with an axis of rotation and a second aperture with an axis of rotation wherein the axis of the first aperture is eccentrically disposed with respect to the axis of the second aperture;
rotating said first aperture into alignment with said second aperture;
inserting an end of a shaft through said first aperture and said second aperture;
rotating said second aperture out of alignment with said first aperture and thereby engaging a locking section of a shaft.

2 more elements

A pin lock comprising:

(a) a first locking member having a locking end;
and
(b) a second locking member, including:
(i) an outer housing having a first aperture dimensioned for receiving at least a portion of said locking end of said first locking member, said first aperture having a longitudinal axis;
(ii) a locking mechanism positioned inside said outer housing, at least a portion of which is rotatable between a locked position and an unlocked position;
and
(iii) a locking part rotationally coupled with said portion of said locking mechanism and having an axis of rotation eccentrically disposed with respect to said longitudinal axis of said first aperture, said locking part dimensioned to interact with at least a portion of said locking end of said first locking member, wherein said locking part has a second aperture dimensioned to allow passage of said locking end through said second aperture when said locking mechanism is in said unlocked position and to engage said locking end of said first locking member when said locking member is in said locked position.
