Description

[Detailed Description of the Invention] This invention relates to a room entry control device in which an input unit such as a keyboard for inputting a room entry signal can be stored in a box body when not in operation.

Conventionally, access control devices that control the access of only specific people to laboratories, resource rooms, etc. are generally installed on the wall 1 of the room, such as concrete, in which the device is installed, as shown in Figure 1. A channel-shaped mounting plate 3 is fitted into the recess 2 and fixed with bolts 4, and an input part 5 for inputting a room entry signal such as a mechanical keyboard and a cylinder lock 6 are formed. The flange portion 8 at the top of the attached decorative panel 7 is locked to the claw piece 9 at the top of the mounting plate 3, and the cylinder lock 6 is locked to the lower part of the mounting plate 3 to attach the decorative panel 7 to the mounting plate 3. The input section 5 is fixed to the protective tube 10 which is embedded in the wall 1 and whose lower part penetrates the upper part of the mounting plate 3.
It is constructed by inserting a ribbon wire 11 that connects the controller and the control device.

The door can be unlocked by reciting a code number set in the device and operating a push button on the input unit 5 that corresponds to the number of the code number.

However, in the conventional device, the input section 5 is fixedly attached with the input section 5 exposed to the outside, so if a passerby or the like tampers with the input section 5, the door may open or the device may be damaged. This can lead to increased criminal awareness, especially if it comes into contact with unscrupulous people.

Furthermore, when the device is installed outdoors, since the input section 5 is installed with the input section 5 protruding outward from the decorative panel 7, a gap is created between the input section 5 and the decorative panel 7, and this gap Rainwater or the like may enter from the inside, causing problems such as short circuits in the ribbon wires 11.

This invention takes into consideration the drawbacks of the conventional technology and uses a simple structure to allow the input section to be stored when not in operation. Next, this invention will be described in detail in the drawings shown in Figure 2 and below, which show one embodiment of the invention. This will be explained in detail.

In these figures, the same symbols as those in FIG. 1 and is fixed to the wall 1 with bolts 4.

14 is a protection tube that penetrates the box body 12 in the vertical direction and is introduced into the wall 1; 15 is a ribbon wire for signal transmission housed in the protection tube 14; and 16 is a protection tube 14 inserted through the center. Bearing 1
It is a box-shaped decorative panel rotatably attached to the protective tube 14 by 7, and an input section 5 consisting of a keyboard for inputting a room entry signal is provided on the front surface.

Reference numeral 18 denotes two magnets attached to the upper and lower portions of one side of the decorative panel 16, and the magnets 18 and the box body 12 constitute a locking mechanism for the decorative panel 16.

Next, the operation of the embodiment will be explained.

The magnet 18 is magnetically attached to the front surface of the box body 12, as shown in FIG. 3 or 4, except when the decorative panel 16 is rotated.

That is, when unlocking, as shown in FIG. 3, the magnet 18 is brought into contact with the right edge of the opening 13 of the box body 12 from the back side, and the decorative panel 16 is attached so that its front surface is attached to the box body. 12
It is held in a state facing the opening 13 of.

Therefore, the input part 5 is located in the opening 13, and the input part 5
When the button is pressed according to the code number, an entry signal is input to the control device through the ribbon wire 15, the door is unlocked, and the door is opened.

After the lock is unlocked, if you press the end of the decorative panel 16 on which the magnet 18 is attached, that is, the right side, the magnet 18 will separate from the box body 12 and the decorative panel 16 will rotate around the protective tube 14. As shown in FIG. 4, when the decorative panel 16 is rotated 180 degrees, the magnet 18
The decorative panel 16 is magnetically attached to the left side edge of the decorative panel 3 from the back side, and the rear surface of the decorative panel 16 is located in the opening 13 and is held in a state of shielding the opening 13.

That is, the input section 5 is housed within the box 12.

Note that when the decorative panel 160 rotates as described above, the ribbon line 1
5 is slightly twisted, but since the ribbon wire 15 is provided in a curled state in advance, it will not break.

In addition, when attempting to operate the input unit 5 while the input unit 5 is housed in the box body 12 as shown in FIG.
When the side where the magnet 18 of the decorative panel 16 is attached, that is, the left end, is pressed, the magnet 18 is detached from the box body 12 and the decorative panel 16 rotates.
The paper is rotated 80 degrees and the state shown in FIG. 3 is reached, and the input section 5 can be pressed.

Incidentally, when one of the buttons of the input section 5 is pressed, a rotational force is applied to the decorative panel 16, but the decorative panel 16 is held without rotating by the locking mechanism.

That is, as shown in FIG. 3, the distance a from the center of the front surface of the decorative panel 16 to the end on the side where the magnet 18 is provided is the distance a from the center of the decorative panel 16 to the magnet 18 side of the input section 5. Since the distance to the button is greater than the distance to the button, magnet 1 is now
If the adsorption force on the box 12 due to the magnetic force of the magnet 8 is Fl, and the pressing force on the input section 5 is F2, then unless the input section 5 is pressed too strongly, the moment exerted by the magnetic force of the magnet 18)FI
Xa is the moment acting due to the pressing force on the input section 5)
F 2 Thicker than Xb (the decorative panel 16 does not rotate.

Further, when rotating the decorative panel 16, it is sufficient to press the end portion of the panel 16 with a force greater than the attraction force of the magnet 18.

As described above, according to the room entry control device of this invention, a box body with an open front is attached to the wall of the room, and the front side of the panel is
Forming the input section for entering the room entry signal, one panel is attached to the box body.
By providing an 80-degree rotation and a locking mechanism that holds the front and rear sides of the panel in their respective openings, the input section can be stored inside the box when not in use.
It will not be tampered with, and when installed outdoors, the rear surface of the panel will be located at the opening of the box body, there will be no movable parts on the rear surface of the panel, the rear surface can be formed watertight, and an inexpensive drip-proof structure will be achieved.

In addition, if the box and panel are made in the same color as the wall to which they are attached, they will be less visible to third parties when not in use.
