Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement of an embedded alarm unit.

[Prior Art] It is desired that an alarm unit of this type not give a sense of incongruity to a resident when attached to a wall surface, is easy to attach, and has an aesthetically invisible mounting screw. However, there is no conventional type satisfying such a demand.

[Problem to be Solved by the Invention] Therefore, an object of the invention is to provide an embedded alarm unit that does not give a feeling of strangeness to a resident even when mounted on a wall surface and does not show the mounting screw from the outside.

[Means for Solving the Problems] In the present invention proposed to achieve the above object, a display panel for notifying a fire or the like is provided on a front panel, and an alarm for stopping an alarm operation of these alarm means. A receiver body provided with a stop switch, a mounting frame having a mounting screw hole fitted and fixed to an outer peripheral portion of the receiver body, and a locking claw on a frame edge for receiving the mounting frame of the receiver body Forming an insertion hole, forming a plate frame having an opening window into which the receiver body is fitted, and forming a locking claw to be fitted and locked in the locking claw insertion hole of the plate frame on an inner surface of the frame portion. And a decorative plate having an opening window for exposing the surface of the receiver body.

Hereinafter, the present invention will be described based on the illustrated embodiment.

The storage case 1A of the receiver body 1 is formed into two parts, a cover 12 having a front panel 11 and a body 13, as shown in FIGS. 1 and 2, and a printed circuit board 2 on which electronic components are mounted. 3 is built-in.

The receiver body 1 is connected to a disaster prevention sensor (not shown) such as a fire sensor or a gas sensor, processes an abnormality detection signal from the disaster prevention sensor, and drives and turns on the alarm lamp 21 and the like. The receiver main body 1 is shown in FIG.
As shown in (b), the printed wiring board 2 can be formed in a horizontal type and a vertical type. 24 is a reset switch for restoring the alarm operation.

As shown in FIG. 2, the printed wiring board 3 has a mounting cut-off portion 32 for the transformer 31 and has a structure in which only the cut-off portion 32 is dropped in the direction of the front panel 11.
Storage case 1A regardless of the fixed position of the printed circuit board 3
If the height inside is more than the height of the transformer 31, the printed circuit board 3 can be accommodated. Note that the lead wires of the transformer 31 are connected to the printed circuit board excluding the cut-off portion 32.

The front panel 11 has a lamp window corresponding to the alarm lamp 21.
11a and 11b are formed, and a switch operation button 11c that is elastically deformable by a split groove corresponding to the switch component 22 is formed integrally with the front panel 11. A terminal block 13a is attached to the body 13, 13b is a fuse, and 13c is a fuse cover.

Reference numeral 14 denotes a nameplate.
a, gas display section 14b and alarm stop switch button display section 14c
Is printed.

The nameplate 14 is attached to the front panel 11 and
a, 11b and the switch button 11c.

FIG. 4 is an exploded perspective view of the embedded alarm unit of the present invention.

The front panel 11 of the receiver body 1 is provided with display units 14a and 14b for notifying a fire or the like, and an alarm stop switch 14c for stopping an alarm operation of an alarm unit.

Reference numeral 4 denotes a mounting frame in which a mounting screw hole 15 and a locking claw through hole 42 are formed in the frame body, and the mounting frame is fitted and fixed to the outer peripheral portion of the receiver main body 1. Reference numeral 5 denotes a mounting screw receiving piece 51. A recess 6 such as a switch box formed on a wall surface attached to the inner surface, and a frame 6 engages with a locking claw 62 which is fitted into a locking claw insertion hole 71 formed on a frame edge 73 of the plate frame 7 and locked. Opening window formed on the inner surface of the unit and for exposing the surface panel 11 of the receiver body 1
The decorative plate 61 on which the decorative frame 61 is formed forms a frame edge 73 for receiving the mounting frame 4 fitted and fixed on the outer peripheral portion of the receiver main body 1, and a plate frame on which an opening window 72 for fitting the receiver main body 1 is formed. It is.

According to the alarm unit of the present invention having such a structure,
The plate frame 7 is put on the upper surface of the recess 5 such as a switch box formed on the wall surface where the mounting screw receiving piece 51 is mounted on the inner surface, and fitted on the outer peripheral portion of the receiver body 1 at the frame edge 73 of the plate frame 7. After receiving and supporting the fixed mounting frame 4, the mounting screw 41 is inserted through the mounting screw hole 15 of the mounting frame 4, and the mounting screw 41 is screwed into the mounting screw receiving piece 51.

Then, the plate frame 7 is sandwiched between the mounting frame 4 to which the receiver main body 1 is fixed and the wall surface, and the receiver main body 1 is mounted on the wall surface while being fitted into the recess 5 of the wall surface. The locking claw 62 of the mounting frame 4 is
Is inserted into the locking claw insertion hole 71 formed on the edge of the frame of the plate frame 7, as shown in FIG. 5, the plate frame 7, the decorative plate 6, and the surfaces of the receiver main body 1 are separated from the wall surface. It can be mounted with only the panel 11 protruding.

Therefore, in such a structure, when the wall surface is viewed from the front, only the decorative plate 6 and the surface panel 11 of the receiver main body 1 exposed through the opening window 62 appear, and the plate frame 7 includes the wall surface, The locking claw 62, which is sandwiched between the mounting frame 4 and formed on the inner surface of the decorative plate 6, is also attached to the mounting frame 4.
Since it is locked by the plate frame 7 closer to the wall,
The amount of protrusion from the wall can be reduced by that much, and it is smart and there is no feeling of oppression.

In addition, with such a structure, since the mounting screws and screws do not appear on the appearance, the appearance is improved.

[Effect] According to the present invention, only the surface panel and the decorative plate of the receiver body appear on the wall surface, and the amount of protrusion from the wall surface can be reduced as compared with the conventional structure, so that the residents do not feel oppressed.

Further, if the receiver main body is configured according to the shape of the existing switch box, the receiver can be used as it is, which is economical. Further, screws and screws are not exposed to the outside and the aesthetic appearance is improved, so that they have high practical value.
