Bit for motion of cross-bar is made separate from key and mounted into body keyhole, and in position LOCKED prevents penetration of skeleton keys to suvalds. Limiter is secret and its size is preset by owner and remains secret for foreigner. Key bit is assembled of semicylindrical pins, which, when pressed-on, fix one another and tightened in keyhole. To adjust key bit for selected version of combination, lock mechanism has coding system in which code plates 6 are installed in full compliance with installation of same plates in suvalds. Lock has small suvald which fixes cross-bar in cases whenever pressing out of main suvalds exceeds rated value amounting to 0.2-0.3 mm.

Title: Method of pressing metal component from sheet blank
Inventor: HUELSBERG THOMAS
IPC: B21D26/02
Filed: 1998-08-29
Granted: 1999-11-18
Abstract: The invention relates to a method for forming a hollow body (1) which is roughly hewed in a forming tool that comprises an upper part and lower part in order to obtain a preform (29) by crushing, using the upper part of the tool, whereby said preform roughly approximates to the transversal contour of the forming chamber that is formed when the forming tool is closed. The preform is then given a final shape (31) in a forming tool (2) at high internal pressure by applying a high internal hydraulic pressure inside the roughly hewn hollow body, whereby said final shape corresponds to the transversal contour and results from expansion. The aim of the invention is to ensure a safe production process for the hollow body which, as a blank, has surfaces (27) that run at a sharp angle to the direction in which the upper swage is lowered and which enter into frictional contact therewith during preforming. In order to achieve this, preforming occurs during impingement of the surfaces of the hollow body that are disposed at a sharp angle to the direction in which the upper swage is lowered and which enter into frictional contact with the upper swage during the closing movement thereof, by means of a roller (12) that is integrated into the upper part of the tool. The invention also relates to a device that can be used to produce a hollow body.
