Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch device that automatically opens and closes a door using the tread pressure of a passerby, and in particular, a switch mechanism that is integrated with a tread plate is fitted into grooves provided on both sides of a sill groove for an automatic door. This invention relates to a switch device for automatically opening/closing a door equipped with a door.

Various types of rubber Matsu switches have already been proposed as switch devices that automatically open doors at entrances and store entrances by the pressure of the foot of a passerby, such as a person entering or leaving the room. These matsuto switches are equipped with a surface switch in which flat conductive plates are arranged on both the upper and lower surfaces of an elastic porous plate, and this surface switch is arranged between a rubber upper plate and a lower plate. It is molded by gluing the peripheral parts of the upper and lower rubber plates. However, when such rubber pine switches are installed on both sides of an automatic door groove rail, the total distance between the width of the rail groove and the peripheral adhesive parts of the mats on both sides may reach approximately 40 cm, making it difficult for passersby to cross the groove. There is a drawback that if one inadvertently stops on the rail, the door that has been opened will suddenly move in the closing direction, creating a dangerous situation.
Furthermore, if the lead wire breaks from the base of the mat or the storage surface switch is damaged while using a rubber mat switch, it is impossible to repair or replace only the damaged parts and reuse them, which is extremely uneconomical. It was hot.

The present invention eliminates the above-mentioned defects and is characterized by providing an elongated switch mechanism on at least one end of a tread made of a rigid plate material, and the switch mechanism is elastically connected to a groove provided in the floor surface. When the switch mechanism sinks due to the load applied to the footboard of a passerby, the contactor is pressed against the floor surface of the groove and becomes electrically conductive, creating an electrical connection with the drive mechanism. The control circuit is configured to open the door and close it after a predetermined period of time has elapsed. An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, columns 3 and 4 are provided inside the walls 1 and 2 that partition indoors and indoors, and between the columns 3 and 4 there is a suspension that is opened and closed by the device of the present invention. A type automatic door 5 is provided. A sill groove 10 having a U-shaped cross section and consisting of both side walls 7, 8 and a floor wall 9 made of stainless steel plates and aluminum plates is provided at the sill portion for receiving the guide plate 6 at the lower end of the door 5.
is provided. Groove portions 11 and 12 constituting the present invention are provided adjacent to both sides of the sill groove 10. The groove portion is arranged and fixed from the bottom surface of a plate material having a U-shaped cross section and consisting of a wide floor plate 13 and both side walls 14 and 15 so as to embrace the threshold groove 10. A holding member 16 having an inverted U-shaped cross section is fitted into the grooves 11 and 12. Both legs of the holding member 16 prevent deformation of the side walls 7, 8, 14, 15 due to external force, and also prevent grooves 11, 12.
The height of the bottom surface 17 of the holding member 1 can be adjusted.
It is also possible to store and arrange various members inside 6 as necessary. A rib 18 bent outward and downward from the upper end of the side wall 15 is provided to reinforce the threshold. When installing the device of the present invention at the same time as constructing a new building, the sill section configured as described above is used, and when the grooves 11 and 12 are added to the existing sill groove 10 later, concrete mortar is poured in contact with the sill groove 10. What is necessary is to excavate and raise the parts, place U-shaped grooves 11 and 12 which are formed separately, adjacent to each other, and fix them with concrete mortar. Furthermore, there is a partition wall 20 between the column 3 of the mullion 19 that stands on the outdoor side at the center of the threshold.
will be established.

A tread plate 22 and a switch mechanism 23 provided at one end of the tread plate 22 are connected to the groove portion 12 and the substantially horizontal floor surface 21 on the indoor side.
The device 24 of the present invention consisting of the following is attached. Treadboard 2
2 is formed into a substantially rectangular shape using a light alloy material or plywood so as not to bend so that it acts as a rigid body under the tread force of a passerby.

It is preferable that the switch mechanism 23 uses a frame 26 made of a square pipe extruded from aluminum. The upper surface of the top wall 27 of the frame body 26 is connected to the tread plate 22.
It is fixed to the lower surface of the inner wall edge with tapping screws 28. As for the fixing means, ribs may be provided when the square pipe is extruded and fit into grooves provided on the tread and the bottom surface.

As shown in FIG. 3, elastic bodies 29 made of rubber or constituent resin are usually fixed to both ends of the lower surface of the frame body 26.
An opening 31 is provided by cutting out the lower wall 30 of the inner frame portion where both elastic bodies 29 are disposed, and both openings 3
1, place the upper surface of the housing of the micro switch 32 on the top wall 2.
7Fixed to the bottom surface. A push button 33 is made to protrude downward from the lower surface of the waterproof casing of this microswitch. An adjustment plate 34 made of a metal plate made of the same material as the frame is fixed to the lower surface of the frame 26 between both microswitches 32 to form a substantial lower surface 35 of the frame. The elastic body 29 is compressed by the load applied to the treadle, and the push button 33 is also compressed from the groove bottom surface 1.
When the lower surface 35 of the frame body, which is the lower surface of the adjustment plate 34, is pressed by the groove bottom surface 1
I am trying to make contact with 7.

In another embodiment of the switch mechanism 23, the lower wall 30 of the frame 26 to which the elastic body 29 is fixed is cut out, and the elastic body 29 fixed to the lower surface of the top wall 27 protrudes below the frame 26. . If the lower surface of the casing of the micro switch 32 is placed in a position substantially aligned with the lower surface of the lower wall of the frame 26, there is no need to attach the adjustment plate 34.

The elastic body 29 is not particularly limited to being made of rubber or synthetic resin, and may be an elastic body made of a curved elongated steel plate. Furthermore, the elastic body and the arrangement position of the micro-switch 32 may be changed, and the key is that the micro-switch is not damaged and the door is opened/closed by ensuring electrical continuity with the pressure applied to the micro-switch.

A second embodiment of the present invention is installed in the outdoor groove portion 11 and the floor surface 36 whose outer side is inclined downward. The device 37 of this embodiment has the same structure as the device 24 except that an elongated rubber member 38 having a wedge-shaped cross section is interposed between the upper surface of the frame 26 and the step board 22. The wedge-shaped inclination angle of the rubber material 38 is the same as the floor surface 36.
The frame body 26 is formed at the same angle as the inclination angle of the groove part 1.

A protector 40 having a U-shaped plane is provided on the outer edge and both side edges of the footboard 22 disposed on the floor surfaces 21 and 36.
It is preferable to fix it to the floor surface. This protector 4
0 is molded from rubber or synthetic resin. Then, the edge of the treadle is placed on the upper surface of the platform 41, and the rising surface
42, and the upper surface outside the rising upper edge is structured as an inclined surface 43 to prevent pedestrians from stumbling.

A lead wire 39 drawn out from the casing of the microswitch 32 is disposed within the frame 26. Then, when passing through the next micro switch 32, it is inserted through a small hole provided in the fixing member 44. Furthermore, the support column 4 is inserted through the edge material 45 provided at the edge opening of the frame body 26.
The inside is placed above and then connected to the drive mechanism. The edge material 45 has a flange 47 at one end of the square tube part 46, and a split groove 48 into which the lead wire can be easily inserted.
The outer surface of the flange 47 is in slidable contact with a support or the like. 4
9 is a stopper, and the bottom plate 1 of the grooves 11 and 12
3, a rising part 51 is made up from one end of the mounting part 50, and a groove-shaped part 52 is provided from the upper end of the rising part 51, and this groove-shaped part 52 has a lead wire arranged therein. Prevent damage. Further, when the frame 26 rises through the opening of the edge material 45, the side plates of the groove-shaped portion engage with the upper surface of the lower part of the opening, and descend to press the push button 3.
3 engages with the lower surface of the upper part of the opening when electrically conductive. Reference numeral 54 is another embodiment of the stopper, which is bolt-shaped and has its lower end fixed to the floor plate 13 through the upper and lower walls of one end of the frame and the holding member 16, so that the frame can be raised. When the head 55 is engaged with the head 55.

The operation of the apparatus of the present invention constructed as above will be explained. When a person walking in and out of the house applies a load to the extent that the entire foot of one foot is pressed against at least the inner side of the outer edge of the footboard, both elastic bodies 29 of the switch mechanism 23 are compressed. When the push button 33 is compressed by the bottom surface 17 of the groove and becomes electrically conductive, the lower surface of the frame 26 comes into contact with the bottom surface 17, and at this time, the door is opened via the drive mechanism. When the pedestrian passes through the treadle facing the door at a normal walking speed, the opened door closes.

6 and 7 show a third embodiment of the present invention, in which the floor surfaces on both sides of the door 5 are dug up and an embedded switch device 60 is installed. As shown in both figures, a metal joint frame 61 having a rectangular plane is buried in the trenched portion on the side of the sill groove 10. Grooves 65 formed by bending a metal plate into a U-shape are provided on the inner surfaces of the opposite side frame portions 62 and 63 of the joint frame and on the upper surface of the reinforcing bottom plate 64, respectively. The holding member 16 used in the first embodiment is fitted into the groove 65. On the other hand, a switch mechanism 23 having the same structure as that used in the first embodiment is fixed to the lower surface of both end edges of the footboard 66, and is fitted into both grooves 65. The upper surface of the tread plate 66 is disposed so as to be flush with the floor surface 21 when no tread force is applied.

Embedded switch device 60 configured as described above
Unlike the stationary device shown in FIG. 2, the device does not have a step that protrudes from the floor surface, and there is no risk of tripping for passersby. Furthermore, since electrical conduction is achieved by the pedal pressure, even if the tread plate 66 is lowered by about 3 to 4 mm, there is no problem with walking and the user can walk smoothly. Furthermore, if a beautiful woven fabric sheet is placed over the treadle to cover it, the indoor environment will be good and it will be suitable for walking, such as wiping dirt off shoes.

FIG. 8 shows a fourth embodiment of the present invention, which is a device 70 to be installed on a step (not shown) in front of the entrance door of a passenger car or the like. That is, a groove 71 is provided on the side of the step passage parallel to the passage direction, and the lower surface of one end edge of a tread plate 72 is fixed to the upper surface of the frame of the switch mechanism 23 attached to the groove. A falling part 73 is provided from the outside of the side wall, and a flat step 74 is provided from the lower edge of the falling part 73, and the lower surface of the step 74 is electrically conductive when the switch mechanism 23 is lowered by the pressure of the foot. It is designed so that it touches the step when the In this device, only the tread portion of the treadle may be inserted, or a rubber protector may be placed around the tread.

In this device, which has the above-mentioned function, a pair of tread plates that open and close the door with a tread pressure load can be placed on both sides of the door sill groove, leaving the width of the sill groove. However, unlike conventional devices, there is no wide range of non-conductivity or dead area, and there is no danger of the door closing inadvertently due to constant body weight being applied to the footboard.

Furthermore, the components of the treadle and switch mechanism that make up the device of the present invention are designed to be easily assembled and disassembled, so if any individual component is damaged during use, the entire device can be replaced as a new device. Instead of replacing damaged parts with other parts, it is possible to immediately replace individual damaged parts on-site as needed. Therefore, this device is extremely suitable for installations where automatic doors are frequently used by people entering and exiting.
