Small holes 11c and 11c for inserting the mounting screws 11b and 11b are formed through the edge and the lower edge, respectively.

  A locking recess 11d is integrally formed on the upper side of the frame (FIG. 4), and a boss 11e having a screw hole is integrally formed on the lower side.

  Around the back surface of the mounting member 11 serving as a mounting surface to the mounted portion A, the bottom surface of the mounting member 11 is continuously extended over the upper side and the left and right side portions so as to form an inverted U shape. The concave groove 11f constituting the concave portion is formed by integral molding of synthetic resin.

  The concave groove 11f is a groove having a semicircular cross section, and is used to apply a caulking agent E to the groove during construction and store a part of the caulking agent in the groove. And it forms in the position made to oppose the outer peripheral wall surface of the square installation hole B formed in the to-be-attached part A made of wood.

  That is, the vertical and horizontal external dimensions of the mounting member 11 are made larger than the vertical and horizontal dimensions of the square installation hole B, and the concave groove 11f is configured to be positioned on the outer peripheral wall surface of the square installation hole B (FIG. 4).

  In the figure, 11 g is a drain hole formed in the lower side of the mounting member 11.

  The intercom handset 12 constitutes a device main body that accommodates the electric circuit of the present invention. In this embodiment, internal devices constituting a communication circuit, a calling circuit, an imaging circuit, and the like for constituting a color TV door phone are provided. The case body 12a is housed.

  The case body 12a is made of a synthetic resin having heat resistance, light resistance, and electrical insulation, such as polybutylene terephthalate (PBT), and the surface of the case body 12a is a lighting device a made of a white light emitting diode, a camera Part b, speaker c, microphone d, call button e, etc. are provided (FIG. 1).

  In the case body 12a, a hook 12b is integrally formed on the upper side portion, and an attachment hole 12d for inserting the attachment screw 12c is formed through the lower side portion.

  At the time of construction, the hook 12b engages with the locking recess 11d of the attachment member 11 (FIG. 4), and the attachment screw 12c is inserted into the attachment hole 12d and screwed into the screw hole of the boss portion 11e of the attachment member 11.

  As shown in FIG. 1, the interphone master unit 13 is installed indoors so as to be communicable with the interphone slave unit. The interphone master unit 13 includes internal devices constituting a communication circuit, a calling circuit, an image receiving circuit, and the like for constituting a color TV door phone. The case body 13a is housed.

  The case body 13a is made of a synthetic resin having heat resistance, light resistance and electrical insulation, such as polybutylene terephthalate (PBT), and has a monitor screen f made of liquid crystal, a speaker g, A press talk button h, a call button i, and a monitor button j are provided.

  Further, although not shown on the side, a power switch, a brightness adjustment volume, a ringing volume adjustment knob, a reception volume adjustment knob, a transmission volume adjustment knob, and a microphone are provided on the lower surface.

  The intercom base unit 13 configured as described above is connected to a power supply line, and is further installed with a wiring cord D connected to the intercom handset 12 on a wall surface of a kitchen or the like.

  Next, a construction procedure for installing the intercom apparatus configured as described above will be described.

  First, the interphone cordless handset 12 in which the frame-shaped mounting member 11 and the main body case 12a are integrated is taken out, the mounting screws 12c are loosened, and the mounting member 11 is removed from the main body case 12a.

  The silicon-based caulking agent E put in the tube is filled into the concave groove 11f having an inverted U shape on the back surface of the removed mounting member 11.

  At this time, a gel-like caulking agent having a circular cross section is extruded from the tube and filled so as to be applied along the concave groove 11f having an inverted U shape. It is stored so as to be embedded in a semicircular groove, and the other half is filled so as to be exposed to the outside from the groove.

  Next, the mounting member 11 is held by hand, the back surface filled with the caulking agent E of the mounting member 11 is directed to the wall surface of the mounted portion A, and the small holes 11c and 11c of the mounting member 11 and the installation hole B on the wall surface Positioning is performed so that the screw hole C1 of the embedded box C is fitted, and the mounting member 11 is strongly pressed by hand toward the outer peripheral wall surface of the installation hole B on the wall surface.

  By this pressing, the caulking agent E, which is half exposed on the back surface of the mounting member 11, is crushed and spreads between the wall surface of the mounted portion A and the back surface of the mounting member 11, and the mounting member is applied to the wall surface by the viscosity of the caulking agent. Glued.

  At this time, since the attachment member 11 is formed in a frame shape with a synthetic resin and is light, the attachment member 11 is temporarily temporarily fixed at the bonded position.

  In this state, the two mounting screws 11b are inserted into the small holes 11c and 11c and screwed into the screw holes C1 of the embedding box C to be fixed.

  By this screwing and fixing, the caulking agent E that has been crushed and spread between the wall surface of the attachment portion A and the back surface of the attachment member 11 is further crushed and filled (FIG. 4).

  At this time, half of the caulking agent E is crushed and filled between the mounting member 11 and the wall surface of the mounted portion A so that the caulking agent reliably waterproofs the mounting member and the wall surface. Even if rainwater or the like is applied to the interphone slave unit 12, water does not enter the attachment member from between the attachment member 11 and the wall surface A, and does not enter the interphone slave unit 12.

  At the same time, only about half of the caulking agent E is crushed and spread, so that a part of the caulking agent E does not protrude from the outer periphery of the mounting member 11. At this time, it is not necessary to perform the work of forming the caulking agent E as in the prior art.

  Next, the wiring cord D is pulled out from the embedding box C and connected to the terminal of the intercom slave unit 12.

  Next, the hook 12b formed on the main body case 12a is engaged with the locking recess 11d of the mounting member 11, and the mounting screw 12c is inserted into the mounting hole 12d and screwed into the screw hole of the boss portion 11e of the mounting member 11. Fix it. Thereby, the installation work to the to-be-attached part A of the intercom handset 12 is completed.

  The caulking agent E is in a gel state in the initial state, but is cured to change into a rubber-like elastic body when left in the air. In contrast, the interphone slave unit 12 is securely installed on the wall surface and exhibits a further waterproof effect.

  When the wall surface of the attachment portion A is concrete or metal, the installation operation is performed in the same procedure as described above. In particular, in the case of concrete, unevenness is formed on the surface of the wall surface, but since the thickness of the gel-like caulking agent that is exposed about half absorbs the unevenness, the intercom handset 12 should be installed at an angle. Can be prevented.

  According to the above-described embodiment, the caulking agent E is filled in the concave groove 11f on the back surface serving as the mounting surface of the mounting member 11, and is simply pressed firmly toward the outer peripheral wall surface of the installation hole B of the mounted portion A. Waterproof construction can be performed.

  The caulking agent E is stored so that about half of the caulking agent is embedded in the concave groove 11f, and the other half is filled so as to be exposed to the outside from the concave groove. 11 and the wall surface of the mounted portion A are filled and spread, so that reliable waterproof construction can be performed.

  At the same time, a portion of the caulking agent E does not protrude from the outer periphery of the mounting member 11, and the appearance is not impaired.

  Further, the caulking agent E is crushed and spreads between the wall surface of the mounted portion A and the back surface of the mounting member 11, and the mounting member 11 can be bonded to the wall surface and temporarily fixed. Screwing work with screws and the like becomes easier and construction work becomes easier.

  Furthermore, since a simple construction in which a concave groove 11f having an inverted U-shape is formed on the back surface of the attachment member 11 enables reliable waterproof construction by simple construction work, it is advantageous in terms of cost.

  Since the concave groove 11f is formed on the back surface of the mounting member 11 so as to have an inverted U shape except for the bottom surface portion, the bottom surface portion of the mounting member 11 is open without a caulking agent. For this reason, even if rainwater or the like enters the mounting member, water is drained from the drain hole 11g formed in the lower side of the mounting member 11, and does not stay in the mounting member. There is no risk of equipment failure.

  According to the present embodiment, unlike the conventional patent document 1, it is not necessary to prepare a packing material separately, and troublesome work such as positioning of the packing material at the time of construction becomes unnecessary.

  In addition, since a part of the caulking agent E does not protrude from the outer periphery of the mounting member 11, after filling the caulking agent as in Patent Document 2, the operator uses a finger or a special spatula jig. There is no need to extend the caulking agent to form the surface, and the construction work is not time-consuming.

  Further, the failure of the electric equipment due to forgetting the work of extending the caulking agent, which was a conventional problem, and the appearance problem due to the protrusion of the caulking agent are eliminated.

  In the present embodiment, the concave groove 11f of the mounting member 11 is continuously formed so as to form an inverted U shape over the upper side portion and the left and right side portions of the rear surface. You may form in a letter shape.

  In addition, although the concave groove 11f is configured by a groove having a semicircular cross section, the cross section may be configured by a groove having a V shape or a square shape.

  Furthermore, in order to prevent the coating amount of the caulking agent E from increasing and leaking from between the wall surface and the mounting member 11, the height is low as shown in FIG. The protruding ridge portion 11h having a bank shape with a height of about 0.5 to 1 mm may be integrally formed on the outer periphery of the groove 11f.

  Further, in place of the bank-shaped convex strip portion 11h, a concave groove is further formed on the outer periphery of the concave groove 11f, and the caulking agent E that protrudes is accommodated in the concave groove provided on the outer periphery so as to be external. You may make it not stick out.

  Furthermore, instead of the continuously formed concave grooves, a plurality of concave portions 11f ′ formed of small circular holes as shown in FIG. 5B may be formed in an inverted U shape or a square shape.

  In this example, the intercom device was configured, but the electrical equipment that requires waterproofing, including electronic devices such as outdoor switchboards and wiring equipment, remote controllers for bathrooms installed in the bathroom, televisions for bathrooms, etc. You may make it comprise.

  For example, if the remote control body is installed directly on the mounted part without an attachment member, such as a bath remote control installed in a bathroom, the back side of the cover that houses the electrical circuit of the remote control body is covered. There may be a mounting surface to be mounted on the mounting portion, and a recess for storing the caulking agent may be formed directly on the back surface of the cover.

  The concave portion may be formed not at the periphery of the mounting surface but at the central portion or close to the central portion.

  Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the scope of the present invention.
