  • Security lock for sliding door or window
    Patent number: 5253904
    Abstract: A lock comprising a stationary sleeve, a hollow cylindrical member, a tubular member and a means for rotating the hollow cylindrical member. The stationary sleeve defines a spirally extending slot that extends its entire length. The spirally extending slot is formed between a first edge and a second edge of the stationary sleeve. The hollow cylindrical member defines an axially extending slot that extends its entire length. The hollow cylindrical member is movably positioned within the stationary sleeve. The tubular member has a projecting tab fixed thereto and is slidably disposed within the hollow cylindrical member wherein the projecting tab is slidingly engaged simultaneously within the spirally and axially extending slots. The rotating means causes the hollow cylindrical member to rotate in a first direction or in a second direction. When the hollow cylindrical member is rotated in a first direction, the projecting tab physically contacts the first edge of the stationary sleeve.
