Abstract: A closing edge safety device that triggers a safety response upon contact with an obstacle. The body of the safety device is an elastically deformable profile element that encloses a switch chamber containing a switching strip that carries an electrical current. A prechamber with a switching nub is placed at the leading edge of the safety device, in front of the switch chamber. When an external force is applied to the leading edge of the safety device, the switching nub transmits the force to the switch chamber, which also deforms, causing an interruption in the electrical current on the switching strip, thereby triggering the desired safety response of the closing edge safety device. The closing edge safety device provides improved response to large-area as well as small-area contact with an obstacle and is also suitable for use as a limit switch.

Abstract: A method for creating a key and a female lock part for a lock, whereby just a few parts are used to create a high number of unique locks. A coding part and a blank are affixed to each other to create the key or female lock part. Coding part and blank each have a contact surface, which, when brought together, can rotate continuously relative each other. The coding part is placed on the blank at a desired rotational position and affixed in that position, either by welding or adhesively. To create a lock with a unique lock function, two coding parts with mating contact surfaces are each attached to a blank, The key and female lock part so made function only with each other. In this way, the same basic coding part and basic blank can be used to create a large number of different locks.

Abstract: A safety-switch device for mounting on a movable device. An impact surface is mounted on or assembled in a bracket. The bracket, impact surface, and a mounting surface of the movable device form a protective enclosure around the switch. The switch is a switch strip or a switch mat. The impact surface is a separate, movable, rigid or stiff component that serves as an actuator for the switch and is provided as a component that is easily replaceable. A trigger mechanism is provided between the impact surface and the switch. When the impact surface moves from its resting position to its actuation position, the trigger mechanism trips the switch.

Abstract: A method for coding components of a locking system which are used to code a key and a female lock part. The coding components may be formed integrally with the key and female lock part or be provided as coding discs that are then affixed to non-coded bodies used for the key and female lock part. A blank of an easily machinable preliminary material is separated into two coding parts with a separation cut that simultaneously creates a coding surface on each coding part. These coding parts serve as the model to mold the coding components in a lost-wax process. Each coding part is encased in a material that forms a mold shell. The coding part is then melted or gasified and escapes from the mold shell, which now has a mold cavity that is then cast with the final material to be used for the coding components.
