Description

[Detailed Description of the Invention] The present invention relates to a detection device for automatic door control, and more particularly to a mechanism for determining in which direction the transmitter of the device is oriented during adjustment.

A transmitter emits sound, light, electromagnetic waves, etc. toward entrances and exits that are conventionally equipped with automatic doors, and detects the entry of passersby based on disturbances in these emitted waves and controls the opening and closing of automatic doors. Such a detection device is used.

However, in the case of the above-mentioned existing devices, the mounting angle, which determines the propagation direction of the emitted waves from the transmitter, cannot be easily adjusted, and the applicant has already taken this point into consideration.
We are proposing a device that allows for easy angle adjustment.

As shown in FIG. 1, this device has a mounting base 1 with an open bottom end mounted near the top of an entrance A equipped with an automatic door (not shown ₎ . Transmitter ₂ consisting of 2
is installed internally with the wrapper cylinder 2 ₂ as the lower part, and a transverse shaft pin 3 projecting from the cylinder 2 ₂ is pivotally connected to bearing pieces 4 fixed to the mounting base 1 .

Further, an adjustment operation shaft 5 arranged in parallel below the horizontal axis pin 3 is pivotally supported by operation shaft support pieces 6, 6 fixed to the mounting base 1.
An eccentric cam 7 fitted on the back surface of the directional flap tube 2 ₂ of the transmitter 2 and the flange portion ₂ of the tube 2 2
The eccentric cam 7 is held between the extending pieces 2 and ₄ bent downward from the cam surface ₃ , and its cam surface is brought into contact with both parts.
As a result, the transmitter 2 rotates in the direction of arrow B about the horizontal axis pin 3, thereby adjusting the propagation direction of the wave transmitted by the transmitter 2.

Further, in the lower end opening 1' of the mounting base 1, a translucent closing plate 8 is fitted on the front surface of the directing flap tube ₂₂ , and 9 in the figure indicates the detection sensitivity adjustment axis of the transmitter ₂₁ . ing.

The device is mounted on a mounting base 1 as shown in FIG.
The openings on both sides are closed by screws 11, 11, .

Furthermore, in the proposed device, a reference dot 12 is displayed on the end surface of the operating shaft 5, and a scale 13 is displayed on the side cover body 10, so that the position corresponding to the degree of rotation of the coaxial shaft 5 can be confirmed. I have to.

However, with the above configuration, the adjustment operation shaft 5 is rotated using a screwdriver or the like, and the transmitter 2 is
When trying to adjust the mounting angle, that is, the directivity, since the directivity lever tube ₂₂ cannot be directly checked through the closing cover plate 8, the adjustment operation cannot be felt, and the adjustment is time-consuming and difficult to find the proper mounting angle. In addition to being unable to make adjustments, in reality, when a user contacts us by phone or other means to inform us of an adjustment deficiency, even if we try to convey the adjustment intention of the operator to the user, the difference between the reference dot 12 and the scale 13 may be incorrect. This resulted in the inconvenience that the relationship could not be accurately communicated, and the constructor had to visit the user each time he made a phone call to resolve the user's dissatisfaction.

Therefore, in order to solve the above-mentioned problems, the present invention has been developed by installing a pilot lamp that accompanies the swinging of the transmitter 2 on the front side of the closing cover plate, thereby making it possible to quickly and accurately adjust the installation angle. The present invention aims to provide a detection device for door control.

The following is a detailed description of the embodiment of the present invention shown in FIG. 3 and subsequent figures.The basic structure is the same as that shown in FIG. is fixed to a blind member C installed at the entrance A through a mounting plate 15, thereby allowing the entrance A to be equipped with an automatic door (not shown).

That is, the illustrated mounting plate 15 has a groove 16 opening downward.
at the upper end, and a rib 17 extending horizontally from the lower end to form a substantially inverted L-shaped side surface, the back portion of which is fixed to the side surface of the blank material B.

On the other hand, the mounting part 18 provided on the back side of the mounting base 1 is fitted between the groove 16 and the rib 17 of the mounting plate 15,
The mounting base 1 is fixed to the mounting plate 15 by threading the bolts 19 of the mounting plate 15 into the grooves 16 and tightening the mounting portions 18.

Further, on the mounting base 1, on the mounting portion 18 side, an inner frame 20 having a substantially crank-shaped cross section is fixed by fitting into a groove, and various members such as the transmitter 2 are attached to this. .

That is, as clearly shown in FIGS. 3 and 4, the inner frame 20 has a pair of bearing pieces 4, 4 facing each other in the width direction from approximately the center, and an operating shaft support piece from the lower part. 6 and 6 are provided protrudingly, respectively.

A shaft bearing piece 2 ₅ that stands up from the flange portion 2 ₃ of the transmitter 2 is pivotally mounted between the two bearing pieces 4, 4 via a horizontal shaft pin 3, so that the transmitter 2 A predetermined oscillation wave is emitted from the directional lamp tube 2 ₂ so as to be able to freely change its direction near the entrance/exit A.

Further, an adjustment operation shaft 5 is rotatably pivoted to the operation shaft support pieces 6, 6, and an eccentric cam 7 is fixed to the operation shaft 5, and the circumferential surface of the cam 7 has a directional bumper. The fact that _the screws ₁₁ , 11, .
The operation shaft 5 and the detection sensitivity adjustment shaft 9 of the transmitter 2 are exposed on the side lids 10, 10 fixed to the side lids 10, 10 so that they can be operated from the outside with a screwdriver, and the lower end opening of the mounting base 1 is exposed. is a translucent closing body 8 made of frosted glass, plastic, etc.
It is also the same that the mounting base 1 is closed so that the inside of the mounting base 1 cannot be seen from the outside.

In addition to the above configuration, the present invention includes a mounting arm 22 that extends laterally from one side of the directional flapper tube ₂₂ of the transmitter 2 in parallel with the adjustment operation shaft 5. As shown in FIG. 5, a pilot lamp 24 connected to a control circuit 23 for operating the transmitter ₂₁ of the transmitter 2 is mounted on the front side of the closing cover plate 8. Third
As clearly shown in the figure, a mounting arm 22 is provided on the side surface of the tip of the directional flapper tube ₂₂ and protrudes from the center of its width by means such as spot welding, and a pilot lamp 24 is attached to the tip of the mounting arm 22 pointing toward the closing plate 9. It is attached.

Furthermore, in the illustrated example, as shown in FIG.
