Abstract

PURPOSE:To make the annunciator small by containing a pushbutton switch and a display light into an outer package of a card holder so as to reduce the size of a front panel. CONSTITUTION:Lots of switch sections with display are arranged to a front panel 1 being a resin forming. A card holder 2 is in contact with an arm 15 and contained in a recessed part 3. When the card holder 2 is pressed in a direction of an arrow 17, the arm 15 is deflected in the direction of an arrow 18 and a pushbutton 10 is in contact with a tact switch 8. When the card holder 2 is detached, the card holder 2 restores to the original state by a restoring force of the arm 15 and the pushbutton 10 is detached from the tact switch 8. A name card 6 and a display light 9 contained in the card holder 2 being a transparent resin forming are observed visually externally. The card holder 2 is arranged with compact by containing the tact switch 8 and the display light 9 into the outer package of the card holder 2 in this way and the size of the front panel 1 is made small.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an annunciator installed in a control room such as an office building or a store building, for performing centralized monitoring control of lighting, air conditioning, etc. of the entire building.

[0002]

2. Description of the Related Art A conventional annunciator will be described with reference to FIGS. In the figure, 1 is a front panel of a resin molded product that constitutes an annunciator, and 2 is a card holder of a transparent resin molded product that is fitted into a recess 3 of the front panel 1, and a large number of card holders are arranged on the entire panel. Reference numerals 4 denote rotation spindles provided on both sides of the card holder 2, which are fitted into grooves 5 on the inner surface of the recess 3 to open and close the card holder 2. 6 is a name card held by the card holder 2, 7 is a printed circuit board arranged behind the front panel 1, 8 is a tact switch fixedly mounted on the printed circuit board 7, and 9 is an LED fixedly mounted on the printed circuit board 7. An indicator lamp 10 is a push button fitted into the button hole 11 of the front panel 1 from the inside,
A spring 12 keeps the tact switch 8 apart.
Reference numeral 13 denotes a display hole of the front panel 1, on which the LED indicator lamp 9 is located. As shown in FIG. 8, one card holder 2, one push button 10 and one LED indicator lamp 9 constitute a switch portion with a display, and a large number of this switch portion with a display are arranged on the entire panel. ..

[0003]

As described above, in the conventional annunciator, since the push button 10 and the indicator lamp 9 are arranged on the outer side of the outer shape of the card holder 2, the front panel 1 becomes large and the device becomes large. There is a problem in that the size of the switch is increased and it is difficult to see the boundary between the adjacent switch units with display at a glance, and it is difficult to know which of the display switch units the push button 10 and the indicator lamp 9 belong to.

The present invention has been made in order to solve such a problem, and the push-button switch and the indicator lamp are housed within the outer shape of the card holder, whereby the front panel can be made smaller and the device can be made compact. Since it is possible to see at a glance which of the switch unit with a display the push button switch and the indicator light belong to, it is an object of the present invention to obtain an unloader that has good operability for centralized monitoring control.

[0005]

An annunciator according to the present invention is a transparent resin in which a large number of switch parts with a display are arranged on a front panel of a resin molded product, and the switch parts are attached to the front panel so as to be openable and closable. A card holder that is a molded product, a switch that is turned on by pressing the card holder in the closed state, and an indicator lamp that indicates the on-state of the switch and that is arranged inside the outer shape of the card holder. Is.

[0006]

In the present invention, the push button switch and the indicator lamp are contained within the outer shape of the card holder.

EXAMPLES Example 1. 1 to 5 of an embodiment of the present invention
Will be described. 1 is a front view, FIG. 2 is a right side view, FIG. 3 is a front view showing the switch part with a display of FIG. 1, FIG. 4 is a sectional view taken along line IV-IV of FIG. 1, and FIG. 5 is an exploded perspective view of FIG. It is a figure, and the same code | symbol is attached | subjected to the same or corresponding part as the said conventional thing, and abbreviate | omits description. In the figure, 14 is an opening provided in the bottom surface of the recess 3 of the front panel 1, and 15 is an opening 14
The push button 10 is formed at the tip of the arm integrally connected to the groove 5 side. Reference numeral 16 denotes a display hole provided on the bottom surface of the recess 3 in which the LED indicator lamp 9 is located and is located between the rotation support shafts 4 of the card holder 2.

Normally, as shown in FIG. 4, the card holder 2
Is in contact with the arm 15 and is held in the recess 3 while being supported by the arm 15. In the state of FIG. 4, the push button operation is performed by pushing the card holder 2 in the direction indicated by the arrow 17. By pushing the card holder 2, the arm 15 bends in the direction of the arrow 18, and the push button 10 comes into contact with the tact switch 8. Arm 1 if card holder 2 is released
The elastic restoring force of 5 returns the card holder 2 to the state of FIG. 4, and the push button 10 separates from the tact switch 8. Since the name card 6 held by the card holder 2 of the transparent resin molded product is visible from the outside, the indicator lamp 9 is also visible from the outside.

In this way, the tact switch 8 and the push button 1
If 0 and the indicator lamp 9 are housed in the outer shape of the card holder 2, the card holder 2 can be packed and arranged as shown in FIG. 1, so that the front panel 1 becomes smaller than the conventional one shown in FIG. In addition, since the boundary between the adjacent switch units with display can be seen at a glance, the operability is improved.

When the push button 10 is integrally formed on the front panel 1 by the arm 15 as a resin molded product as in the above embodiment, the number of parts is reduced, the cost is reduced and the assemblability is improved.

Embodiment 2. Another embodiment of the present invention is shown in FIG.
FIG. 7 will be described. 6 is the same sectional view as FIG. 4, FIG.
6 is an exploded perspective view of FIG. 6, and the same or corresponding parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In the figure, reference numeral 2a is a double-sided groove on both sides of the card holder 2 for holding both sides of the name card 6, and 10A is a push button integrally formed at the tip of the arm 15, and the head holder 10a is closed. The name card 6 is sandwiched and held by being pressed against.

As shown in FIG. 6, the elastic force of the arm 15 normally causes the head portion 10a of the push button 10A to press the name card 6, so that the name card 6 does not move or deform, and the characters on the name card 6 disappear. It is easy to read and looks good. Moreover, since there is no play in the card holder 2, rattling can be prevented.

[0013]

As described above, according to the present invention, the push-button switch and the indicator lamp are housed within the outer shape of the card holder, so that the front panel can be made smaller and the apparatus can be made compact, and the operability and the assembling can be improved. It is possible to obtain the effect that the property is improved.
