FIG. 5 is an explanatory cross-sectional view showing a state before the latching frame 33 is latched on the periphery of the notch 24, and FIG. 6 shows a state where the latching frame 33 is latched on the periphery of the notch 24. FIG. FIG. 7 is an explanatory view partially enlarged showing a state in which the tapered surface 33 b of the latching frame 33 is in contact with the notch 24.

  The installation bracket 21 is a rectangular plate made of metal that is slightly smaller than the case body 2, and a plurality of screws for screwing the installation bracket 21 to the wall surface W on the left and right upper edges excluding the lower edge. Holes 22 are formed. In addition, a window 23 is provided in the center of the installation bracket 21 for allowing the control board 3 and the like to escape backward from the installation bracket 21 when the interphone master unit 1 is installed in front of the installation bracket 21. Yes. Further, notches 24 and 24 through which a later-described retaining frame 33 can be passed are formed on the left and right side edges of the window 23, respectively. In addition, positioning holes 25 serving as positioning portions for positioning the interphone base unit 1 relative to the installation bracket 21 when the interphone base unit 1 is hooked to the installation bracket 21 at the four corners of the installation bracket 21; 25 ... are respectively drilled.

  On the other hand, on the rear surface of the case body 2 of the intercom base unit 1, four positioning projections 30, 30... That can be inserted into the positioning holes 25 are provided rearward at intervals corresponding to the positioning holes 25, 25. Has been. Further, on the rear surface of the case body 2 of the intercom base unit 2, when the positioning protrusions 30, 30... Are inserted into the corresponding positioning holes 25, 25, respectively, the positions corresponding to the notches 24, 24 are provided. The retaining members 31, 31 are attached. The latch member 31 includes a solenoid 32 having a plunger 32a, a latch frame 33 assembled to the plunger 32a, and a guide member 34 for guiding the slide of the latch frame 33. The plunger 32a of the solenoid 32 is provided so as to be movable between a protruding position and a retracted position, and is biased to the retracted position when not energized. For example, a predetermined operation is performed on the display screen 5 or the like. When energized, it moves on the protruding position side (that is, in the counter-biasing direction). Further, projections 32b and 32b for assembling the retaining frame 33 are provided at the tip of the plunger 32a.

  The latch frame 33 is a synthetic resin member formed in a substantially square frame shape smaller than the notch 24, and an insertion hole (in which a protrusion 32b of the plunger 32a can be inserted in the lower side portion of the latch frame 33). (Not shown) is provided, and by inserting one of the protrusions 32b into the insertion hole, the latching frame in a state in which the solenoid 32 is housed in the frame, that is, in a state of surrounding the left and right side surfaces and the upper surface of the solenoid 32. 33 and the solenoid 32 can be integrated. Further, the latch frame 33 is formed in such a size that there is a space between the upper side 33a and the upper surface of the solenoid 32 when the plunger 32a is in the retracted position in an integrated state with the solenoid 32. (FIGS. 4A and 4B). As the plunger 32a moves toward the protruding position, the upper side portion 33a comes into contact with the upper surface of the solenoid 32 and functions as a restricting portion that restricts further movement of the plunger 32a toward the protruding position. (FIGS. 4C and 4D). Further, the rear surface of the upper side portion 33a of the retaining frame 33 is provided with a tapered surface 33b that gradually becomes thinner upward so that the upper edge becomes the thinnest. In addition, guide protrusions 33c are extended in the vertical direction on the front surfaces of the left and right side portions of the retaining frame 33, respectively.

  The solenoid 32 and the latching frame 33 integrated as described above are arranged so that the plunger 32a faces downward, and the guide member 34 is interposed between the latching frame 33 and the case body 2 so that the solenoid 32 is disposed. Is fixed to the rear surface of the case body 2 by the fixture 35, so that the hooking member 31 is provided on the rear surface of the case body 2. Therefore, when a load is applied to the latch frame 33 in the counter-bias direction of the plunger 32a or the load is released, the latch frame 33 and the plunger 32a are attached to the guide member 34 based on the fixed position of the solenoid 32. It is possible to move up and down while being guided. In addition, a pair of rail grooves (not shown) are provided on the rear surface of the guide member 34, and the guide protrusions 33c and 33c of the latch frame 33 are fitted into the rail grooves.

  Then, the installation method on the wall surface W using the installation bracket 21 of the interphone master unit 1 will be described. First, the control board 3 and the like can be stored in the wall surface W, and the hole H ( In particular, the positioning holes 25, 25,... Are larger than the drilling positions and the screw holes 22, 22,. Next, the installation metal fitting 21 is fixed to the peripheral portion (that is, the wall surface W) of the hole H by screwing. After that, the positioning protrusions 30, 30... Are inserted into the positioning holes 25, 25... (FIG. 5), and then the interphone master unit 1 is hooked by the latch members 31, 31 on the upper edges of the notches 24, 24. What is necessary is just to push in back substantially (namely, wall surface W side) until it stops. At this time, after the tapered surface 33b of each latching frame 33 abuts on the upper edge of the notch 24, a downward load is applied to the tapered surface 33b, and the latching frame 33 is subjected to the urging force of the plunger 32a. It slides downward gradually while resisting (FIG. 7). Finally, when the latching frame 33 passes through the notch 24 so as to pass through from the front to the rear, and moves rearward from the mounting bracket 21, this time, due to the biasing force of the solenoid 32, The plunger 32a is returned to the retracted position, and the retaining frame 33 is located at the retaining position, that is, the retaining member 31 is latched on the upper edge of the notch 24 (FIG. 6). Completed.

  On the other hand, when removing the intercom master unit 1, when a predetermined operation is executed on the display screen 5, each solenoid 32 is activated, and the plunger 32 a is moved until the upper side 33 a of the latching frame 33 contacts the upper surface of the solenoid 32. Move to the protruding position. That is, the latching frame 33 slides downward, and the upper side 33a of the latching frame 33 is positioned in the notch 24, and the latching of the latching member 31 to the notch 24 is released. Therefore, if the intercom base unit 1 is pulled out in this state, the intercom base unit 1 can be removed.

  According to the installation structure of the intercom base unit 1 having the above-described configuration, the solenoid having the notches 24 and 24 in the installation bracket 21 and the plunger 32a urged to the retracted position on the rear surface of the interphone base unit 1. 32 and mounting members fixed to the wall surface W, each provided with a latching member 31, 31 provided with a latching frame 33 that slides in the moving direction of the plunger 32a along with the movement of the plunger 32a. 21, the load is applied to the latching frame 33 of the latching member 31 and slides in the counter-biasing direction together with the plunger 32 a while passing through the notch 24 from the front to the rear, and then to the latching frame 33. When the load is released, the plunger 32a is returned to the retracted position by the urging force, so that the retaining frame 33 is also moved. And a latching mechanism that member 31 is hooked on the peripheral edge of the notch 24. Therefore, since the interphone master unit 1 does not fall off the installation bracket 21 unless the latch member 31 is removed from the notch 24, the interphone master unit 1 installed on the wall surface W is not suitable, for example, when a resident responds. It becomes difficult for the situation to drop off easily.

  Further, a taper surface 33b that gradually becomes thinner toward the end edge is provided on the rear surface of the latch frame 33 so that the end edge becomes the thinnest, and the taper surface 33b is a peripheral portion on the front side of the notch 24. When the intercom base unit 1 is pushed backward while in contact with the hook, the load is applied to the hooking frame 33 and the plunger 32a in the counter-biasing direction, and the hooking frame 33 slides downward while protruding the plunger 32a. It is configured. Therefore, the interphone base unit 1 can be hooked on the installation bracket 21 simply by pushing the interphone base unit 1 backward from the front side of the installation bracket 21, and the installation work of the interphone base unit 1 becomes very easy. .

  Further, the latching frame 33 is assembled so as to surround the solenoid 32, and as the plunger 32a moves to the protruding position side, the upper side 33a of the latching frame 33 comes into contact with the upper surface of the solenoid 32 and the plunger The movement of 32a to the further protruding position side is restricted. Therefore, the movable region of the plunger 32a can be suppressed to a small space, and the space on the rear surface side of the case body 32 can be effectively used.

  In addition, positioning holes 25, 25... Are provided in the mounting bracket 21, and positioning protrusions 30, 30. Therefore, simply by inserting the positioning protrusions 30, 30... Into the positioning holes 25, 25..., The hooking members 31, 31 can be positioned to the positions corresponding to the notches 24, 24, and installation work can be performed. It becomes even easier. Further, the intercom master unit 1 is temporarily locked by the insertion of the positioning protrusion 30 into the positioning hole 25 except for the forward movement of the interphone master unit 1 and then the latch member 31 is hooked to the upper edge of the notch 24. Can be restricted from moving forward. Therefore, the installation state of the intercom base unit 1 on the wall surface W can be set to be killed, and the drop-out of the intercom base unit 1 can be reliably prevented.

  In addition, the installation structure of the intercom device according to the present invention is not limited to the aspect of the above embodiment, and the configuration related to each interphone device as well as the configuration related to the latch member and the mounting bracket are not limited to this configuration. The present invention can be changed as needed without departing from the spirit of the invention.

  For example, in the above-described embodiment, only two latching members 31 are provided, but three or more or only one latching member 31 may be provided, and the number of the latching members 31 can be changed as appropriate. . Further, the posture when installing the latch member 31 is the same in both the left and right in the above embodiment, but it may be installed in the opposite direction. Therefore, if the latching member 31 is provided in such a posture that the plunger 32a is actuated in the radial direction one by one on the top, bottom, left, and right of the case body 2, the latching members 31, 31,.・ Installation on the installation bracket 21 is possible only by this.

  In the above-described embodiment, the positioning hole 25 and the positioning projection 30 are employed as the temporary fixing mechanism. Instead, a hook-shaped locking claw is engaged with the installation bracket 21 on the upper rear surface of the case body 2. A locking portion such as a locking recess or a locking piece that can be locked by a pawl is provided to constitute a temporary locking mechanism, and the same latching members 31 and 31 are provided at the lower part of the case body 2. A simple installation structure is also conceivable. According to this configuration, the intercom base unit 1 is not pushed in horizontally as in the above embodiment, but the locking claw is locked to the locked portion and is then swung rearward around the locking position. By pushing in like this, the intercom master unit 1 can be installed. Even when such a configuration is adopted, the upward movement of the intercom base unit 1 that cannot be regulated by the temporary fastening mechanism can be regulated by the latching members 31 and 31. In other words, it is possible to realize a snap-off structure as in the above embodiment, and to achieve other effects in the same manner, such as simplification of installation work.

  Further, in the above embodiment, the solenoid 32 biased to the retracted position is employed, but conversely, it is possible to employ a solenoid biased to the protruding position, and a spring or the like is used instead of the solenoid. There is no problem even if a latching member in which the claw piece is urged in the direction in which the latch is held is used. Furthermore, a pressing projection protrudes from the retaining frame 33 to the outside of the case body 2 without providing the tapered surface 33b or the like. In the above embodiment, the retaining frame 33 is automatically pushed in response to the rearward pushing. It is also possible to configure so that the worker moves while the operator presses the pressing projection and pushes down the retaining frame 33.

In the above embodiment, the intercom master unit 1 is attached by opening the hole H in the wall surface W. However, by providing the installation bracket 21 with legs and the like, the hole H is not opened. The intercom base unit 1 can be installed, and there is no problem even if the case body 2 is formed by assembling the front case and the rear case as in the conventional case.
In addition, although the installation structure of the interphone master unit 1 has been described, the installation structure of the present invention can also be favorably applied to other interphone devices such as an interphone slave unit installed at the entrance.
