| Abstract: |
A locking device for releasably securing a first member to a second member which second member has an opening therein for receiving a portion of the first member, a groove in the portion of the first member within the opening, a cylindrical pin in the second member extending across the opening in the first member and in the groove in the second member in one angular position thereof, a portion of which pin is removed so that in another angular position the pin does not extend into the groove in the first member. In one modification, the pin is bowed slightly to provide spring like interference to movement thereof. In another modification, the central portion of the pin is eccentric whereby the central portion of the pin extends into the groove in the first member in one rotated position of the pin, and is completely out of the groove in another rotated position. In a further modification, the second member includes a cylindrical selecting part and a rotatably mounted securing part. In this embodiment, the securing part has a sigle opening therethrough and the selecting part has a plurality of radially extending angularly spaced apart openings in the outer periphery thereof which can be aligned with the single opening of the securing part, while the second member includes a pin secured thereto operable to extend through the single opening of the securing part and any of the selected openings of the selecting part of the first member.

I claim:
1. A locking device for releasably securing a first member to a second member comprising an opening in the second member for receiving a portion of the first member, a groove which is generally orthogonal with the axis of said opening located in the first member extending transverse to the opening in the second member positioned on the first member so as to be within the second member with the first member inserted in the opening in the second member, a cylindrical passage in the second member extending orthogonally of the opening therein, located so as to align with the groove in the first member positioned within the second member and across the groove in the first member, a cylinder pin extending into the passage in the second chamber a lever on one end of the pin and means operable between the lever and second member to secure the lever in at least one rotated position of the pin whereby a second lock between the first and second member is provided.
