Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a switch panel that automatically opens and closes a door using the pressure applied by a person entering or exiting the door. Set up a switch,
The present invention relates to a switch panel that opens and closes a door via a control circuit when electrical conduction occurs due to the pressure of a person entering or exiting the door.

(Prior Art) Many types of switch devices have already been proposed that automatically open a door by the pressure of a passerby's foot. Typical examples include a switch mat in which a switch member is sealed in a pair of rubber or synthetic rubber plates, and a switch device in which a waterproof micro switch in the form of a housing is disposed on the lower surface of a rigid plate.

(Problems to be Solved by the Invention) However, with the switch mat made of the rubber plate mentioned above, if a heavy object being transported is carelessly placed on the mat or passed by a trolley, the golf shoe The enclosed switch member may be damaged by spikes, etc., or the rubber plate may be torn, making it unusable. It was complicated to carry out the work.

Furthermore, in a switch device equipped with a micro-switch member, if the device itself shifts on the floor due to the kicking force of the pedestrian's lower leg, the elastic member that protrudes downward and contracts under pressure to provide electrical continuity will be damaged. However, it is said that it only moves up and down. Therefore, a vertical flange must be provided on the periphery of the footboard to which the microswitch is fixed, and a lower plate having a flange slidably fitted to the flange on the floor side must be formed in the shape of a housing. It didn't happen. Such a complicated configuration not only increases the production cost, but also requires the use of a rigid and expensive treadle to minimize the number of more expensive micro-switches in the lower plate and move them further away from the switch position. The switch was set to remain on even if a pedestrian stepped on it. Furthermore, a micro switch consisting of a sealed housing is naturally limited in its small size, and has a height that makes it easy for pedestrians to trip over it, so it has to be installed in a rectangular recess dug into the floor. There were many problems.

(Means for solving the problem) The present invention is a floor-standing type that does not dig into the floor surface or engage with grooves provided in the floor.
No damage even when heavy objects are placed or passed through.
Furthermore, it is an object of the present invention to provide a switch panel that will not malfunction even if light objects such as dust and debris are blown onto it.

In order to achieve the above object, the present invention forms an upper plate made of a thin plate made of hard synthetic resin with impact resistance and viscoelasticity, and the entire periphery of the lower surface of the upper plate is flexible and returns under pressure. The thickest elastic material that can contract freely is arranged in a series, and sealed pressure-sensitive switch elements thinner than the peripheral elastic member are provided at equal intervals on the lower surface of the upper plate, and the pressure-sensitive switch elements are thinner than the peripheral elastic member. An inner elastic member, which is thinner than the peripheral elastic member and thicker than the pressure-sensitive switch, is disposed at the appropriate location.

(Function) In the switch board constructed as described above, even if a light pet animal such as a dog, a cat, or an infant passes over the board, the elastic material will not contract until the switch element is closed. When a child who weighs more than the specified weight walks or a load of that weight is placed, the upper plate of the pressurizing part is distorted and deforms downward, and the elastic material contracts, causing the switch element closest to the pressurizing part to Close. Then, a motor rotates a control circuit in the lintel at the entrance and exit, opening the door. When a heavy object passes over the switch board, the hard, viscoelastic top plate is distorted and deformed without breaking or being damaged. At the same time, the switch element, which consists of two curved electrode plates whose elastic material shrinks to about half its thickness, will not be damaged even if it is pressed flat.

The switch element is hermetically coated with a synthetic resin material, and the connection part with the coated conductor is filled with adhesive sealing material and connected watertight, so even if water leaks when the switch panel is placed directly on the floor, there will be no electricity. No malfunctions or rapid deterioration of parts occur.

(Example) The present invention will be explained below based on the accompanying drawings.

In FIG. 1, columns 2 and 3 that hold the wall 1
An entrance/exit is formed, and a plurality of doors 4, which are automatically opened and closed by an electric control circuit, move on rails 5 at the entrance/exit. A pair of floor-standing, foldable switch boards 7 are arranged on both side floor surfaces 6 of the rail 5 in close proximity to the rail 5.
An exterior sheet 9 that covers the switch panel is arranged with a hook 8. This sheet 9 is made of a flexible synthetic resin plate with anti-slip protrusions,
As shown in Fig. 2, edge material 10 made of vinyl chloride resin
is installed so that it fits on the floor.

In FIGS. 2 and 3, upper plates 11a and 11b of the switch board 7 are foldably connected by a hinge 12. As shown in FIGS. The upper plates 11a and 11b are made of impact-resistant, oil- and water-resistant materials such as acrylic resin and polycarbonate resin, and can be made as thin as about 2.5 mm. It is preferable to connect rectangular plates with a hinge and use them as the rectangular upper plate 11 in the horizontal direction with respect to the entrance/exit.

As shown in FIG. 4, a metal hinge 12 is used as the hinge 12 with an intervening member 13 interposed therebetween, but the structure is not particularly limited to this, and a flexible piece of nylon resin may be used. As a result, as shown in FIG. 4, it is convenient to fold it into a small size and transport it in large quantities for storage, storage, and installation.

An outer elastic material 15 having a rectangular cross section is attached to the entire periphery of the lower surface of the upper plate 11, except for the conductor lead-out portion 14 and both sides of the hinge 12, by bonding, fusing, vapor deposition, or other means. The outer elastic material 15 is a foamed synthetic rubber consisting of independent cells, and has a hardness of 35.
~40, preferably 40. Furthermore, it is chemical resistant, water resistant, flexible and highly elastic. This outer elastic material 15 is made to be the thickest in order to hold the entire outer frame of the switch board 7, but in the case of this embodiment, the height is 10 mm, and the width varies depending on the size of the upper plate, but normally It is about 15-25mm.

Covered conductor wires 16a,
A holding cover 18 is fixed to the holding cover 16b for tightly holding an electric circuit in which a plurality of switch elements 17 are connected. An inner elastic member 19 is provided between the electric circuits, and a support 20 is provided at the connection portion between the upper plates 11a and 11b.

The switch element 17 has both upper plates 11a and 11b.
are arranged symmetrically on the back surface of the
They are spaced at approximately equal intervals at a, and the spacing is such that no matter which part of the upper plate is pressed with tread pressure, it will turn on. In this embodiment, six pieces are provided on one upper plate 11a. As shown in FIG. 6, this switch element 17 is made by overlapping a pair of curved, copper-plated, thin steel electrode plates 22a and 22b, with the lower electrode plate 22a exposed only at the center of its upper surface. An insulating sheet 23 made of a resin material is wound and covered. Then, both electrodes 22a and 22b are polymerized to form a space 2 having a flat cross section and a flat outer sheath 24 made of vinyl chloride resin.
Accommodate in 5. A protrusion 26 is provided on the top of the outer sheath 24, and when the protrusion 26 is lowered by the pressure applied from above, the electrodes 22a and 22b are electrically connected.
Preferably, both electrodes 22a and 22b are provided with a protrusion 29 for connecting the covered conductor 28. The switch element 17 configured in this manner seals both ends of the outer cover 24 with a sealing material such as a sealant.

The switch elements 17 are connected in parallel to the circuit diagram of FIG. 7 by conductive wires 28. In the circuit diagram, loop-shaped covered conductors 16a and 16b are connected to 30a and 30a, respectively.
Connect 0b. The number of conductive wires 30a and 30b can be increased or decreased depending on the number of switch elements. Although the conductive wires 16a and 16b are not shown, they are connected to a power source via a control circuit for opening and closing the door. The present invention is not limited to this electric circuit, and a switch element may be connected in parallel to a pair of conductive wires.
This coated conductor is fixed to the upper plate with a clamp 32 and led out from the drawer part 14, and a plug 33
Connect to the outlet on pillar 3.

The switch element 17 is held by a holding cover 18 attached to the top plate. The holding cover 18 is made of a synthetic resin material that is water, oil and abrasion resistant, has a hardness of about 40, and has flexibility and elasticity, and as shown in FIG. and a flange 3 extending laterally from the upper end of the side wall 34.
6 is provided, and a protrusion 37 is provided inwardly from both side walls 34.
The switch element 17 is reserved. The holding cover 18 has a thin wall thickness, approximately 1.5 mm in this embodiment, and the height from the top surface of the flange to the lower surface of the bottom wall is lower than the outer elastic member 15, and in this embodiment, the height is 6.5 mm to 1.5 mm.
7.5 mm, preferably 7 mm. Although the planar shape of the holding cover may be formed to cover the switch element 17 and the wiring, in the case of this embodiment, an E-shaped one is used symmetrically. However, when the switch board is constructed from only one plate, it is suitable for forming the switch board to have a Japanese character shape. The part of the holding cover from which the covered conductor is pulled out is sealed watertight with a sealing material.

The inner elastic members 19 are attached to the upper plate at equal intervals between the electric circuits. This inner elastic material is made of the same material as the outer elastic material, and has a lower elasticity than the outer elastic material, and in this embodiment, it is 7.5 to 8.5 mm, preferably 8 mm. Therefore, it is higher than the holding cover.

Support members 20 are provided on both sides of the folding connection portions of the upper plates 11a and 11b. This supporting member 20 is lower than the holding cover 18 and has a height of 5 to 50 cm in this embodiment.
6 mm, preferably 5.5 mm, and the hinge 1
It is approximately the same height as 2. This support material 20 is made of hard natural rubber, and has a hardness of 60 in this embodiment. This support material 20 is disposed in a portion where an elastic material is not provided at the connecting portion consisting of two upper plates, and when a tread force or a heavy object is applied to the connecting portion, the upper plate becomes large. This prevents the upper plate from becoming deformed, which would impede walking, and prevent damage to the upper plate. In addition, the switch element 17 is
This is because the upper plate is already compressed and electrically conductive before it comes into contact with the floor surface, and the upper plate does not require any further deformation.

The switch panel 7 of the present invention having the above structure is supported by the outer elastic member 18 when it is placed on the floor as shown in FIG. It has an interval. Even if the peripheral edge of the upper plate 11 is pressed by the foot, the outer elastic member 15 and the upper plate 11 at the pressed portion are compressively deformed and press the switch element 17. In this switch element 17, the protrusion 26 portion contracts and descends to form the upper electrode 22.
b contacts the exposed upper surface of the lower electrode 22a and turns on.
becomes.

When the central part of either of the upper plates is pressed, the outer elastic member 15 is slightly compressed as a whole, and the pressed part is distorted and deformed downward, and after the inner elastic member 19 is compressed, the switch element contracts. and ON
becomes.

(Effects) The present invention, which has the above-mentioned action, has a space between the holding cover that covers the switch element and the inner elastic material when the switch board is placed on the floor, so that it can be placed on the concrete floor. Even if the surface is rough or uneven, the switch element will not malfunction, and there is no need to provide a bottom plate as in the conventional case, and it can be placed on the floor.

Furthermore, since the switch panel placed on the floor is in contact with the outer elastic material, it will not shift even if it comes into contact with a pedestrian's foot, and the switch will not shift even if it is displaced by a strong impact force. Since the holding cover that covers the element does not come into contact with the floor surface, it will not be damaged by friction and can be used for a long time.

Furthermore, since both the switch element and the holding cover that protects the element are watertightly sealed, there is no possibility of malfunction even if the floor surface is washed with water or water leaks, and there is no danger to passersby.

Further, even if the switch board is inserted into a recess in the floor surface and its upper surface is arranged evenly with the floor surface, there will be no problem and many beneficial effects will be produced.

Furthermore, conventional matsuto switches require a large number of switch elements to be placed directly below the treading part, but with the present invention, the upper plate is only slightly deformed due to the elastic material. Since the switch elements separated from the tread pressure section are electrically conductive, it is sufficient to provide an extremely small number of switch elements.

Further, an electrode plate 22 constituting the switch element
a, 22b used extremely short lengths,
By using long switch elements disposed within the outer elastic material, it is possible to further reduce the number of switch elements disposed.

Furthermore, the present invention allows the door to open when an object heavier than the child's weight passes over the switch panel, but if you want the door to open even when a pet such as a dog or cat passes by, you need to open the door between the outside and inside. This problem can be solved by reducing the hardness or narrowing the width of the elastic member.
