Definitions
- the invention relates to a safety mat as a safety device according to the preamble of the main claim.
- EP 0421 048 A1 describes a safety strip which is to be used as a switch mat, a large number of contact elements and wedge elements being provided which are pulled towards one another by an expander cord, the wedge elements being designed as wedge plates, the contact elements being designed as contact plates, and wherein When ready to switch, the expander cord lies in the contact plates and in the wedge plates at different heights.
- This arrangement creates a switch mat which can extend over a relatively large area and which can be easily passed over by vehicles, but which triggers corresponding switch contacts even at low loads.
- Switching elements are connected over a large area by the expander cord and that the switching elements are not designed as independent, individual safety switches, but this switching mat is ultimately a single safety switch with the disadvantage that an error in the entire mat renders the entire mat unusable and this Inoperability is ultimately difficult to notice.
- the invention has for its object to provide a safety mat which has safety switches, each of which forms a unit for itself, these safety switches now being able to be connected to one another, so that adaptations to a wide variety of geometric shapes in which the safety mat is used are thus achieved should, is possible.
- a plurality of individual safety switches forming a unit can be connected to one another.
- these individual safety switches now together with z. B. can be clipped, so that the construction of a safety mat is possible, which has any geometric shape.
- This can also be done in such a way that, for example, the individual safety switches which form a unit are arranged in a plate-shaped mat which has at least one top covering and one bottom covering, this mat then being adapted to the desired geometric shape. Areas that are free of safety switches can then be provided in this mat.
- the safety switches can be designed as break contacts or make contacts, combinations of these two switch designs also being possible.
- Multi-channel capability is also possible, e.g. B. that two closed circuits are provided, which are separated.
- Fig. 1 shows an arrangement of safety switches, one with closed contact, the other with open contact, the individual safety switches are arranged in a mat, in Fig. 2, the combination of safety switches and in
- 3 shows the geometrical shapes possible, for example, with the design according to the invention.
- 1, 2 and 2 denote two safety switches which are arranged within a mat, the mat being formed at least from an upper surface 3 and a lower surface 4.
- the switches 1 and 2 can be moved against the restoring force of spring elements 5 and 6 under load.
- In the housings 7 and 8 of the switches 1 and 2 there are electrical contacts 9 and 10 which cooperate with electrical contacts 9a and 10a which are provided in the pressure mushrooms 11 and 12.
- the electrical line within the pressure mushrooms 11 and 12 is designated 14 and 15.
- a second circuit is formed by lines 26 and 27.
- FIG. 3 four different geometric shapes are shown merely as exemplary embodiments and to clarify the inventive concept, example I representing a simple triangle, while examples II, III and IV show that differently designed geometric plates can be placed against one another and this enables adaptation to the desired geometric shape in which the safety mat is to be provided.
- the drawing does not show that the individual safety switches can be firmly connected to one another, for example they can be clipped together, so that when the safety switches are arranged within a mat formed by the top surface 3 and the bottom surface 4, the safety switches do not move is possible, which could otherwise result in rooms that are not covered by safety switches.
