Description

[Detailed description of the invention] <Industrial application field> This invention relates to the Matsuto switch.

<Problems to be solved by this invention> Conventionally, as seen in Japanese Utility Model Publication No. 10745/1983, a mat switch has a planar space provided between an upper mat member and a lower mat member, and Since they have been formed by incorporating a mechanism that operates a switch by applied pressure, there is a problem in that many steps are required for manufacturing, which prevents efficient production. Also,
There was a problem that a gap sometimes formed between the upper mat and the switch mechanism, and the switch did not operate even if the switch was stepped on. The present invention attempts to solve such problems.

<Structure of the invention> The present invention provides flat pedestals that protrude downward on the four circumferential parts of the mat, and recesses the lower surface of the flat plate portion formed between the pedestals at the protruding portions of the pedestals. A pin switch characterized in that a continuous groove such as a meandering groove with an open bottom surface is provided, a pressure conductive wire is fitted into the continuous groove, and one surface of the pressure conductive wire is projected by the protrusion of the base. .

<Example> Examples will be described below based on the drawings.

A downwardly inclined surface 1 is provided on the upper surface of the four circumferences, and a flat pedestal 2 is formed by protruding downward the lower surfaces of the four circumferences,
A mat member 4 is formed by recessing the lower surface of the flat plate portion 3 surrounded by the pedestal 2 at the protrusion of the pedestal 2, and an opening 5 is formed in the lower surface of the flat plate portion 3 of the mat member 4 to form a meandering continuous groove 6. establish. Incidentally, the meandering continuous grooves 6 are formed with parallel intervals as small as possible, as shown in FIG. In this continuous groove 6, there are conductive flat mesh wires 7a, 7b and a pressurized conductive elastic body 8 between them.
A pressurized conductive wire 10, which is entirely covered with an insulating covering material 9, is inserted, and the lower surface of the wire 10 protrudes from the protrusion of the base 2 to form a mat switch. Reference numerals 11a and 11b are small fitting portions having projections and depressions.

Note that FIG. 2 shows an example in which small circular raised ridges 12 and receiving ridges 13 are provided at intervals between the continuous grooves 6 on the upper and lower surfaces of the flat plate portion 3.

Further, FIG. 3 shows an example in which the continuous groove 6 provided in the flat plate part 3 is opened not only in the lower face but also in the upper face, and the pressure conductive wire 10 is inserted with the upper face also protruding from the flat plate part 3.

In the pine switch made in this way, the lower surface of the voltage conductive wire 10 is grounded together with the lower surface of the pedestal 2, so if the pine is stepped on by a person coming in or out or a heavy object, the pressure conductive wire 10 will be securely grounded. When pressure is applied, a switch is activated to open and close the automatic door.

<Effects of the invention> As described above, the present invention has constructed a mat switch with a simple structure in which a continuous groove such as a serpentine groove is provided in the flat plate part of the mat member and a pressure conductive wire is fitted therein. Matsu switches can be efficiently produced with fewer steps, resulting in lower manufacturing costs and a matsu switch with fewer failures.

In addition, the lower surface of the flat plate part of the mat member is recessed at the protrusion of the pedestal around the four circumferences, and one surface of the pressure conductive wire fitted to the flat plate part is made to protrude at the protrusion of the pedestal. The lower surface is in contact with the floor surface and compresses in response to the pressure of the foot, thereby producing a reliable switching effect.
