Definitions
- the invention relates to a pressure sensitive Switching device in the form of a flat safety mat according to the preamble of the main claim.
- Machines may only be placed on the market if Protection of the operator complies with comprehensive safety aspects become. This also includes the protection of danger areas on machines where there is presence or access with the machine running because of the outgoing machine Dangers must be prevented. To protect people Safety mats are exposed to the dangers of this kind used.
- Closing principle in which two conductive strips or layers brought together when entering the mat or electronic principles where a beam of light is interrupted becomes. These configurations need to transform the output signal a special evaluation device.
- the switch mat consists of Series of mechanically positive opening contacts in the form of contact elements.
- Current-conducting contact elements and insulating wedge elements are alternately on lined up with an expander cord. By preloading the contact elements pressed together and the closed circuit is closed.
- entering the safety mat is about the wedge elements of at least one of the contact element pairs disconnected and the power line interrupted. With these safety mats no additional evaluation device is required.
- the invention is based, for a safe task to ensure foreign matter-free laying of the safety mats at the same time but make sure that when the safety mat stretches due to thermal or mechanical stress Destruction of the edges of the safety mat cannot occur.
- the damping elements are preferably designed as a hollow profile, which is technically easy to manufacture and assemble is.
- the safety mats have a cover plate and a base plate, it is advantageous to use the hollow profile or the damping element to be provided with an insert pin of the same material, which can be used between the base plate and the cover plate is. This is a safe on the one hand, on the other easy setting and attachment of the damping elements guaranteed.
- a switch mat 1 is shown, for example to a wall boundary 4 or to a ramp profile 3 adjoins, of course, by the invention is also included that a switch mat 1 to another Safety mat 1 can border.
- a damping element 2 which consists of there is a hollow profile and, for example, an insertion pin 5, with which this damping element 2 between a cover plate 6 and a bottom plate 7 of the switch mat 1 can be used.
- the damping element 2 takes up this expansion, by compressing the damping element 2, whereby is ensured in the installed state according to FIGS.
- a Safety edge are used, such as from is known from DE 100 02 926 C1 or in another form belongs to the state of the art, so in this area still a hedge in addition to the normal hedge the safety mat is coming.
