Abstract:
A door closer with a housing, a brake piston mounted in the housing and operable to axially move therein in response to an external force, a shaft mounted in the housing and coupled to the brake piston so as to rotate in the housing while opening or closing a door, and a locking element provided with a spring which biases the locking element towards the shaft so as to lock the shaft in at least one angular position thereof.
Abstract:
Device and method for the remote diagnosis and/or remote monitoring and/or remote initialization of a microprocessor-controlled door, door system or garage door system operated by an electric motor. The microprocessor control can be connected with a data transmission device for the performance of a remote diagnosis and/or remote monitoring and/or remote initialization of the microprocessor control. The data transmission device can have a modem adapter. The modem adapter can connect the microprocessor control to a cellular telephone, which cellular telephone can be dialed through a cellular data network. The cellular telephone can also be part of the data transmission device. The data transmission device can simultaneously be effectively connected to a service center.
Abstract:
A fastening of end caps to housings that are made of profiles and are used for door-specific devices on automatically operated doors. The end caps are thereby invisibly clipped or clipped in a concealed manner onto installation elements that have previously been connected with the sections, whereby at least one of the installation elements is simultaneously used as a fastening for the housing.
Abstract:
A door hinge includes a body received in a cutout provided in the edge of a glass door, a pair of plates which grip the glass door and hold the body in the cutout, and lights on an edge of the body received in the cutout.
Abstract:
Holder for plates, in particular glass plates with borings or holes, whereby in each boring is inserted an annular body with an internal or female thread and an outside facing made of an elastic material. A threaded bolt for the connection to a load-bearing construction can be screwed into the annular body. The punctiform holder makes possible a pivoting and displacement of the glass plate within certain limits. It can be installed quickly and easily.
Abstract:
The movable partition system has a plurality of movable partition elements placed on a horizontal rail. Each of at least two of the movable partition elements has its own electric motor. Each electric motor has a current collector connected to it which passes along at least two conductor rails which are part of the electrical circuit when the electric motor is moved. These rails are connected via lines to a control unit which controls the power supply and the operation. One conductor rail is connected with a single line. On the other hand, at least one other conductor rail has a plurality of lines which lead to electrical connections or taps which are isolated from one another by insulators. This isolation permits the control unit to control the individual flow of current to each separate tap. This makes it possible to individually control and position the individual movable partition elements.
