Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a display device which is held horizontally along a wall surface or the like in a non-display state, protrudes from the wall surface or the like in a display state, and is illuminated.

[0002]

2. Description of the Related Art Conventionally, in order to display, for example, "in-room", "in use" or "in business", a display body in which those characters are written is installed horizontally on a wall surface,
A display device configured to illuminate a display body in a display state in which "in-room", "in use", or "in business" is displayed is known.

[0003]

However, according to the above-mentioned conventional configuration, since the display state of "in-room", "in use" or "in business" is simply displayed by illumination, it is exclusively displayed. There is a disadvantage that the display state cannot be confirmed unless the front position of the device is approached, and the display function is also insufficient.

[0004]

In order to solve the above-mentioned disadvantages of the conventional ones, the present application is driven by a drive motor and the drive motor via a transmission mechanism, and
A rotating drum provided with a display body having an illumination mechanism, and a control circuit for controlling the rotating drum forward and backward at a required angle, energizing the illumination mechanism during forward rotation of the rotating drum, and releasing the energized state during reverse rotation. Preferably, the transmission mechanism is a gear transmission mechanism, a slip mechanism is interposed between the gear transmission mechanism and the rotary drum, and the required angle is about 90 °. Set to.
The display body is detachably attached to the rotating drum so that the display body can be replaced. Specifically, the rotating drum is made of a vertically long member, and the side surface of the rotating drum extends in the longitudinal direction to insert the display body. In addition to providing the insertion port which allows, a holding cylinder having an elastic holding portion inside, and vertically disposing a plurality of terminal pieces including a terminal piece capable of conducting electricity with the control circuit The holding part is provided so as to face the insertion port. Further, the control circuit includes an actuating cam that rotates together with the rotating drum, and the turning on of the actuating cam causes the actuating cam to act relatively with respect to the actuating cam and to be turned off when the actuating cam is operated.
A pair of detection switches and a relay having a first contact and a second contact that switch relative to each other when the operation switch is turned on to convert the polarity of the drive motor, and a circuit that energizes the illumination mechanism when the operation switch is turned on. The detection switch is connected between the switching contact of the first contact, which is relatively switched, and both ends of the motor.

[0005]

In operation, when the display is inserted into the insertion port of the rotary drum and the operation switch is turned on, the lighting mechanism is energized and the relay is operated, so that the pair of relay contacts are connected. At the same time as switching, the motor rotates in the forward direction due to the ON state of one of the detection switches, which also rotates the rotating drum via the transmission mechanism, and the display rotates from the horizontal non-display state to the right-angle display state. To do. This rotation causes one of the detection switches to act on the actuation cam to turn it off, so that the rotation of the motor is stopped. In this case, even if the motor excessively rotates beyond the display state due to inertia, the rotation is absorbed by the slip mechanism, and the display body is set at a predetermined position. Next, when the operation switch is turned off to return the display body from the right-angled display state to the horizontal non-display state, the energized state of the illumination mechanism is released, and
Since the pair of relay contacts are switched and the other detection switch is already turned on, the motor rotates in the opposite direction, which causes the rotating drum to rotate in the opposite direction and the display body to move horizontally from the right angle display state. Return to the hidden state of. By this rotation, the other detection switch acts on the operation cam and is turned off, so that the rotation of the motor is stopped.

On the other hand, a series circuit of the operation switch SW and the relay R,
A pair of relay contacts RA and R which change the polarity of the driving motor 1 by switching the both ends by the operation of the relay R.
B and the switching contacts a ^' , b of one relay contact RA

A pair of detection switches LS ₁ and LS ₂ for operating N and OFF to detect the rotation direction of the drive motor 1 are connected in parallel, and the operation cam 45 is fan-shaped.
Further, the pair of detection switches LS ₁ and LS ₂ are arranged on the horizontal piece 7b of the substrate 7 so as to abut each other on one side edge when the operation cam 45 rotates by 90 °. The detection switches Switches LS ₁ and LS ₂ are composed of switches that are always ON and that are OFF when they come into contact with the actuating cam 45.
Are connected in parallel.

In use, however, the connecting portion 32 of the horizontally long message casing 31 shown in FIG. It is held by the portion 22a. Then, in the non-display state in which the message housing 31 is parallel to the vertical piece 7a of the substrate 7, as shown in FIG.
When one of the detection switches LS ₁ is turned off by the contact of the contact switch, and the operation switch SW is closed from the state shown in FIG. 7, the illumination light 30 is turned on by the contact between the connection piece 33 and the terminal piece 22. , The relay R operates so that one relay contact RA changes from the switching contacts a, a ′ to b, b ′, and the other relay contact RB changes from the switching contacts c, c ′ to d ,.
Since they are respectively switched to d ′, the switching contacts b and b ′, the detection switch LS ₂ , the driving motor 1, the switching contacts d and d ′.
Drive circuit 1 is rotated in the forward direction, and this rotation also rotates the rotating drum 5 in the forward direction via the gear transmission mechanism 2 so that the message housing 31 is parallel to the vertical piece 7a of the substrate 7. The display is rotated from the display state at a right angle to the vertical piece 7a, that is, from the state shown by the solid line in FIG. 3 to the state shown by the phantom line in FIG. In the above, when the drive motor 1 rotates, the actuating cam 45 separates from the _one detection switch LS _1, so the detection switch LS ₁ is turned on, but the switching contacts a, a ′ and c, c ′ are both non-contact. Since it is in the conductive state, the forward rotation of the drive motor 1 is maintained.

Then, the rotary drum 5 is rotated by 90 °, the message casing 31 is projected at a right angle, and the illumination lamp 30 is provided.
In the display state in which is lit, the operating cam 45 contacts the other detection switch LS ₂ , so that the detection switch LS
₂ is turned off, the energizing circuit of the drive motor 1 is cut off, the rotation of the drive motor 1 is stopped, and the state shown in FIG. 8 is obtained. In the above, the drive motor 1 rotates by 90 degrees or more due to the inertia of the rotary drum 5, but the gear transmission mechanism 2
Between the terminal gear 20 and the rotating drum 5 of the slip mechanism 4
Since 0 is intervening, the excessive rotation due to the inertia of the drive motor 1 is absorbed by the slip of the friction piece 41, and the rotary drum 5 is correctly rotated by 90 °.
Since 1 projects at a right angle and is illuminated, the message display can be easily confirmed from the outside.

When the operation switch SW is turned off in order to restore this state to the non-display state, the illumination lamp 30 is extinguished, the relay R is deactivated, and the relay contacts RA, R.
B is switched, and the switching contacts b and b'and the contacts d and d'become non-conductive again, one of the switching contacts a and a'of the relay contact RA and the other switching contact c and c'of the relay contact RB.
Are turned on, and the switching contacts a, a ', the detection switch LS ₁ ,
An energizing circuit for the drive motor 1 and the switching contacts c, c'is formed, and the drive motor 1 rotates in the reverse direction. This rotation causes the rotary drum 5 and the message casing 31 to return from the display state to the non-display state. The actuating cam 45 has a detection switch L
When it comes into contact with S ₁ , the detection switch LS ₁ is turned off,
The rotation of the drive motor 1 is stopped. In this case as well, the over-rotation of the drive motor 1 is absorbed by the slip mechanism 40. Further, since the operation cam 45 is separated from the other detection switch LS ₂ by the rotation of the drive motor 1, the detection switch LS ₂ is restored to the ON state, and the state shown in FIG. 7 is obtained.

In the above, if some external force acts on the message casing 31 in the non-display state shown in FIG. 3, the rotary drum 5 rotates clockwise in the figure, and the actuating cam 45 causes one detection switch LS. and separated from ₁ Izure detection switch LS ₁ and LS ₂ also to have been placed in oN and state. This is a state in which one of the detection switches LS ₁ is turned on in FIG. 7, so that the energizing circuit of the switching contacts a and a ′, the detection switch LS ₁ , the drive motor 1 and the switching contacts c and c ′ is formed. Then, the driving motor 1 rotates in the reverse direction in the non-display state. Therefore, when the external force is released in this state, the rotary drum 5 rotates in the reverse direction and the message casing 31 returns to the non-display state before the external force acts.

Further, in the above, if some external force acts on the message casing 31 in the display state shown by the phantom line in FIG. 3, the rotary drum 5 rotates counterclockwise in the figure, and the actuating cam 45 moves. When the detection switch LS ₂ is separated from the other detection switch LS ₂ and is placed at an intermediate position where neither of the detection switches LS ₁ and LS ₂ comes into contact, the other detection switch LS ₂ is also turned on in the state shown in FIG. Therefore, switching contact b,
b is ', the detection switch LS _2, the drive motor 1, switching contact d, d' energizing circuit of formation, and forward rotation in the direction of the display state of the driving motor 1, thus when the external force is released in this state , The rotating drum 5 rotates forward and the message casing 31
Returns to the display state before the external force was applied.

Furthermore, in the above, even if an external force acts on the message casing 31 and the message casing 31 is rotated in the display direction or the opposite direction from the non-display state, the rotation is slipped. It is not absorbed by the mechanism 40 and mechanically damages the gear transmission mechanism 2 and the like.

Furthermore, in the above embodiment, the rotary drum 5 is used.
The message housing 31 is attached so that it can be inserted, but if the display of the message housing 31 does not need to be changed, the message housing 31 may be integrally attached to the rotating drum 5. Of course. Furthermore, in the above embodiment, the operation switch is turned on and off from a remote position so that the required display can be made. However, in the case of "in room" or "in use", for example, a person has entered the room. The operation switch may be turned on and off by an electric signal generated when the fact is detected so that the display can be performed.

Furthermore, in the above-mentioned embodiment, as a display body,
Although the case where the message housing 31 having the illumination lamp 30 inside is used is illustrated, a display provided with a plurality of lamps on the outer periphery of the message housing and a control circuit for controlling the blinking of the plurality of lamps inside. Display body having a lighting function, such as a body, a display body formed by arranging a plurality of lamps for display characters themselves, or a display body having a light source and a large number of light guide lines, and displaying display characters by the light guide lines Of course, may be used.

[0021]

As described above, according to the present invention, it is possible to easily confirm the display state from a position away from the display position due to the rotation of the rotary drum and the illumination action, and the display member is provided by the interposition of the slip mechanism. Even if an unnecessary external force is applied to the product, it can be used safely without fear of mechanical damage.
Further, according to the configuration of claim 5, it is convenient when exchanging display bodies having different display contents, and according to the configuration of claim 6, the display bodies can be securely clamped, and further, claim 7 According to the configuration described above, even when the message board is unnecessarily rotated to the intermediate position between them from the non-display state or the display state due to the action of the external force, when the external force disappears, the external force acts on the message board. Since the previous state is automatically restored, there is an advantage that the certainty of the display function can be obtained.
