TH41519A - Cylinder lock and release key for use with cylinder locks. - Google Patents

Abstract

DC60 (06/03/55) The invention aims to present a cylindrical lock and key designed to be extremely difficult to duplicate and virtually impossible to unlock. The device is designed with two freely rotating sockets inserted within socket housing 1. When the key is inserted directly into the socket, the cylindrical lock allows the socket to rotate by placing the end of the loose pin at a position on the surface of the rotation boundary between the socket housing and the socket. One row of loose pins in a group of loose pins is positioned in a way that separates the angle of convergence of pairs of loose pins within another group of loose pins. In addition, the key slot is fitted with a V-shaped projection extending onto the narrow side of the key slot and acting as a guide rail for the key. The invention aims to present a cylindrical lock and key designed to be extremely difficult to duplicate and virtually impossible to unlock. The device is designed with two freely rotating sockets inserted within socket housing 1. Socket housing 1 is designed so that when the key is inserted directly into the socket, the cylindrical locking mechanism allows the socket to rotate. This is achieved by positioning the loose pin end on the rotating surface between the socket housing and the socket. One row of loose pins within a group of loose pins is positioned to separate the convergence angles of pairs of loose pins within another group. Furthermore, the key slot features a V-shaped projection extending from the narrow side of the key slot, acting as a guide rail for the key.

Claims (2)

1. A cylindrical lock where the key slot is formed by two wide, aligned surfaces of the locking and unlocking device. A moving pin is positioned to allow backward and forward movement to one of the aligned wide surfaces and pushed away from the blade. A floating spherical ball is positioned within the blade of the locking and unlocking device to allow free movement. A driven pin is positioned to allow backward and forward movement to another wide surface and is driven in the direction of movement of the floating ball. The floating ball is pushed by the driving pin. The distal ends of the driven pin and the driven pin are positioned on the boundary surfaces of the socket and socket housing when the locking and unlocking device is inserted into the socket. The driven pin and the driven pin are positioned at different angles to the wide surfaces of the locking and unlocking device so that they are not aligned. 2. Locking device and key for locking and unlocking the cylindrical lock. The socket is equipped with several roller pins inserted into the socket housing in a manner that allows them to rotate freely. The blade section is inserted into the key slot of the socket, similar to the ball receiving system with a conical bottom wall. The floating spherical ball is arranged in a ball receiving channel in a manner that allows it to move freely. The ball receiving channel is positioned perpendicular to the wide surface of the blade section. The ball access point is positioned in the conical bottom wall of the ball receiving channel in a way that allows the floating ball to operate only in an inclined direction toward the wide surface of the blade section.
