Abstract A key bolt including a shank having an open transversely disposed bolt slot at one end with an elongated planar key slidably disposed in the bolt slot. The key has end portions and spaced side walls forming a closed elongated key slot disposed intermediate the ends of the key. A pin is transversely disposed in the bolt shank and passes through the bolt slot and through the key slot at substantially right angles thereto to slidably retain the key within the bolt slot. The key is slidable in the bolt slot to an unlocked position wherein the key extends directly outwardly of the shank and forms an extension thereof and is slidable to a locked position wherein the key is substantially perpendicular to the shank. In one form of the invention, at least a portion of one of the side walls of the key is severed or partially severed or slotted intermediate the ends thereof with one severed portion having its free end portion offset from and protruding out of the plane of the key to form a key lock abutting the bolt shank to retain the key in locked position. Such severed portion is yieldable to a position within the plane of the key to enable the key to be moved from locked position to unlocked position.
A key bolt including a shank having a key-receiving shelftype recess formed at one end thereof, an elongated planar key slidably disposed on said recess and having end portions and spaced side walls forming a closed elongated key slot intermediate the ends of the key; and a pin transversely disposed in the shank at said one end thereof and passing through said recess and said key slot at substantially right angles thereto to slidably retain the key within the recess, said key being slidable on said recess to an unlocked position wherein the key extends directly outwardly of the shank and forms an extension thereof and being slidable to a locked position wherein the key is substantially perpendicular to the shank, one of said side walls of the key including an abutment protruding out of the plane of the key to form a key lock abutting the bolt shank adjacent its one end to retain the key in locked position, said key being yieldable to a position spaced from the recess to enable the abutment to be moved from locked position to unlocked position, said one side wall having at least a portion of its outer edge formed into a downwardly turned flange having its inner end forming said abutment, and resilient means disposed between the free end of the pin and the key to bias the key against the recess.
