Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a push button switch structure for an electric shutter that is operated to open and close the electric shutter.

[Problems to be solved by the prior art and the invention] Generally, in this electric shutter, a three-point push button switch for "open", "close", and "stop" is provided to open and close the shutter. However, in the past, the push-button operation section of a typical push-button switch was not illuminated, so it was difficult to press the push-button switch without hesitation in the dark, such as at night, and the push-button switch was often pressed incorrectly. Therefore, a push-button switch with an illumination mechanism installed in the push operation part has been proposed.
These devices illuminate all the push buttons of the three push button switches, so if the shutter cannot be seen directly due to darkness, it is possible to determine the current state of the shutter. Even if the device is illuminated, it has the drawback that it is easy to make mistakes when pressing the button in the dark, which is a problem.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention aims to provide a push button switch structure for an electric shutter that can eliminate these drawbacks. It is equipped with a three-point push button switch for raising, lowering, and stopping,
Lighting lights are provided to light up the push operation parts of at least the up and down switches, and when the electric shutter is fully open, the light for the up push button switch is turned off and the light for the down push button switch is turned off. lights up, and in the fully closed state, the lowering push button switch is turned off and the rising push button switch is lit, and in the halfway stopped state, both illumination lights are turned on. It is something.

With this configuration, the present invention allows you to check the open/closed state of the shutter curtain by looking at the lighting status of the illumination lights even in the dark, and allows you to press the button without making mistakes. It is.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes an electric shutter provided in the opening, and the electric shutter 1 includes:
“Open”, “close”, and “stop” of push button switch 2, which will be described later.
By pressing any one of the push operation parts, the switch 3 (electric motor M) can be driven in forward or reverse direction.
Alternatively, the electric shutter 1 can be opened and closed by stopping the electric shutter 1, as is conventional.

Fig. 2 shows the control circuit wiring diagram of this electric shutter 1. According to this, LSU is an upper limit switch, LSD is a lower limit switch,
MCU is the upper limit relay switch and its switch contacts, MCD is the lowering relay switch and its switch contacts, PBU is the raising (open/close) push button switch,
PBD is a lowering (closing) push button switch, PBS is a stop push button switch, EMS is an emergency stop switch,
Further, as mentioned above, M is an electric motor and B is a brake, and these are also wired in the conventional manner. The portion surrounded by the broken line in FIG. 2 is wired within the switch box of the push button switch 2.

Therefore, in the wiring inside the switch box, the circuit from terminal B2 to the up push button switch PBU is branched at A2, and the branched wiring includes the down push button switch PBD and the stop push button switch PBS. Lighting lights LD and LS1 (for example, neo lamps, light emitting diodes, and other lights with low power consumption are preferable) are connected in parallel. On the other hand, the circuit from terminal B ₄ to the lower push button switch PBD is branched at A ₄ , and the separated wiring includes the upper push button switch PBU,
In addition, illumination lights LU and LS2 are connected in parallel with the stop push button switch PBS. And each of these lighting lamps LD, LU, LS1,
In LS2, when the shutter curtain is fully open and the upper limit switch LSU is open (in this case, the lower limit switch LSD,
and the stop push button switch PBS is closed)
, the circuit leading to terminal B ₄ , via branch A ₄ to terminal B ₃ or to B ₁ is energized, and therefore the lamp
LD and LS1 light up, the lower push button switch PBD,
Each of the stop push button switches (PBS) lights up. On the other hand, when the shutter curtain is fully closed and the lower limit switch LSD is open, the illumination lights LU and LS2 turn on,
Push button switch for raising PBU, push button switch for stopping
It is designed to light up each PBS. Furthermore, when the shutter curtain is stopped at a halfway position, both limit switches LSU and LSD are open, and at this time all illumination lights LD, LU, LS1, and LS2 are turned on. There is.

In the embodiment of the present invention configured as described above, when the shutter curtain is fully opened, the push buttons PBU and PBS for lowering and stopping are illuminated and the shutter curtain is fully closed. If it is stopped halfway, the push buttons for lift and stop (PBD, PBS) will be illuminated, and if it is stopped halfway, all the push buttons will be illuminated.
The push controls for PBD, PBU, and PBS are illuminated.

As described above, in the present invention, the illumination state of the push operation part of the three-point push button switch changes in three ways when the shutter curtain is fully opened, fully closed, and stopped midway. Therefore, even at night when the open/closed state of the shutter cannot be seen, the user can immediately know the open/closed state of the shutter by looking at the illumination state of the push operation section of the push button switch 2. Furthermore, the illumination state is such that when the switch is fully open, the push button of the lowering push button switch PBD that drives the switch 3 downward is illuminated, and when it is fully closed, the push button that moves the switch 3 upward is illuminated. The push operation section of the switch PBU is illuminated, and furthermore, in the case of a mid-stop state, both the push operation sections of the push button switch PBU and PBD for raising and lowering are illuminated. Therefore, in each case, the push operation part of the push button switch that must be pressed is illuminated, which makes it possible to reliably eliminate erroneous presses and to operate the electric shutter quickly and reliably. Can be opened and closed.

Moreover, as in the example, the circuits for each light lamp are housed in the wiring inside the switch box, so even though the light lamps that selectively turn on are provided, wiring work is not required when assembling the electric shutter. , can be carried out no different from conventional methods.

The present invention is, of course, not limited to the above-mentioned embodiments, but can be realized by appropriately changing the color of the illumination lamp or by appropriately changing the lighting condition such as continuous lighting or blinking lighting. This will allow further clarification. Further, in the embodiment, it is also possible to provide upper and lower limit lighting devices 4 separately from the above-mentioned illumination lamp. Furthermore, when the pushbutton switch PBS is used to illuminate the push operation section of the stop push button switch PBS, the illumination lamp LS is equipped with a diode D ₁ in the circuit drawn out from the open side circuit and the closed side circuit, respectively, as shown in Fig. 4. , D ₂ and connect them to the illumination lamp LS in a parallel connection, it is possible to use one instead of two as in the previous embodiment.

[Operations and Effects] In short, the present invention is configured as described above, so when the electric shutter is fully open, the illumination light of the lowering push button switch lights up, and when it is fully closed, the illumination light of the lowering push button switch lights up. The light on the lift push button switch will light up, and in the case of a mid-stop condition, both light lights will come on. Therefore, if you look at the lighting status of these lights, you can see that the shutter curtain is lit even in the dark. The open/closed status of the door can be immediately recognized. Moreover, in this case, since the push button switch to be pushed is illuminated, opening/closing control of the electric shutter can be performed quickly and reliably without any erroneous presses.
