Description

  The present invention relates to an electronic device mounting structure for mounting an electronic device such as a bathroom television to a wall surface.

  When attaching an electronic device in which an electronic component is housed in a housing to a wall surface, a base plate is fixed to the wall surface in advance, an engagement protrusion is provided on the base plate, and an engagement recess is provided on the back surface of the housing, A structure is used in which the housing is prevented from being detached from the engaging protrusion by pressing the housing against the base plate so that the engaging protrusion fits into the engaging recess and further shifting the housing downward in that state.

  However, in a bathroom television, a cable for TV signals and a cable for supplying power are drawn out from almost the center of the back surface of the casing, and can be elastically deformed so that hot water does not enter the casing from the cable drawer. The drawer portion is surrounded by an annular seal member.

  In the mounting structure described above, the casing is shifted downward in a state where the casing is pressed against the base plate. Therefore, there is a problem in that the sealing member is deformed and the sealing performance is lowered.

  On the other hand, with the casing tilted, the upper part of the back surface of the casing is engaged with the upper part of the base body, and the attitude of the casing is returned to the vertical with the engaging portion as the center. There is known a structure in which the lower part of the housing is connected to a wall surface by connecting the lower part (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2010-41086 (FIG. 5)

  The mounting structure disclosed in Patent Document 1 has an advantage that the sealing member is not easily deformed even if the sealing member is attached to the back surface of the casing because the casing is not shifted downward with respect to the base plate.

  However, in order to engage the case with the upper part of the base plate at an angle, and to return the posture of the case to the vertical position in that state, a certain gap must be secured between the case and the wall surface. . However, if the gap is to be blocked with a caulking agent, the caulking agent must be applied over the entire circumference of the housing, and the caulking agent may flow inward from the gap, requiring a large amount of caulking agent, and This causes a problem that the number of work steps for applying the caulking agent increases.

  Therefore, in view of the above problems, the present invention does not deform the seal member even if a seal member is attached to the back surface of the casing, and makes the gap between the casing and the wall surface as narrow as possible. It is an object of the present invention to provide a mounting structure for an electronic device.

Mounting structure of the electronic device according to the present invention in order to solve the above described problems is the mounting structure of an electronic device mounting the electronic component is built enclosure wall, a base plate fixed to the wall, to the base plate The base plate is provided with a fixing bracket that is held so that the longitudinal directions thereof are parallel and slidable in the longitudinal direction , and one side of the housing is engaged with the base plate, and the other side facing the one side Engage one end of the fixing bracket with the screw, attach a screw to the other end of the fixing bracket, and rotate the screw to move the fixing bracket in parallel with the base plate. It is characterized in that the casing is attached to the wall surface without being lifted from the base plate by sandwiching the casing.

  The casing is fixed to the base plate by sandwiching the casing between the fixing bracket and the base plate. At this time, the fixing bracket moves, but the casing does not move with respect to the base plate. Therefore, even if the sealing member is interposed between the casing and the base plate, the sealing member is not deformed. .

  In addition, a cable lead-out portion is provided at substantially the center of the back surface of the housing, and an elastically deformable seal member surrounding the lead-out portion is sandwiched between the back surface of the housing and the base plate, so that the center of the base plate is almost at the center. If the base plate is fixed to the wall surface with a caulking agent applied so as to surround the back side of this opening, the wall surface Hot water that has entered between the base plate can be sealed with this caulking agent.

  As is clear from the above description, the present invention can be fixed without shifting the housing with respect to the base plate fixed to the wall surface.

  With reference to FIG. 1, W is a wall surface of a bathroom, and a bathroom television 3 is attached to this wall surface W by the structure described below. The base plate 1 for attachment is fixed to the wall surface W with screws.

  A pair of left and right fixing brackets 2 are attached to the base plate 1. The fixture 2 is held so as to be movable in the vertical direction, and the upper end 21 is bent obliquely in a key shape. The lower end 22 is formed with a screw hole, and the screw 4 is screwed into the screw hole.

  On the other hand, the lower edge 11 of the base plate 1 is bent obliquely upward, and a lower engagement portion formed on the back surface of the bathroom television 3 engages with the lower edge 11 as described later. And the bathroom television 3 is hold | gripped from the up-down direction by the upper end 21 of a fixing metal fitting engaging the upper engaging part similarly formed in the back surface of the bathroom television 3, and is fixed to the base board 1. FIG.

  With reference to FIG. 2, an opening 13 is formed in the center of the base plate 1 corresponding to a connecting passage H through which a cable, which will be described later, passes, and the periphery of the opening 13 is an annular shape protruding one step forward. A caulking seat 12 is provided. As described above, the base plate 1 is fixed to the wall surface W with screws. When fixing, the base plate 1 is fixed to the wall surface W with the caulking agent 5 applied to the back side of the caulking seat 12. To do. Then, even if hot water enters between the wall surface W and the base plate 1, it is sealed by the caulking agent 5, and hot water can be prevented from entering the inside surrounded by the caulking agent 5.

  With reference to FIG. 3, the upper engaging part 31 and the lower engaging part 32 are formed in the back surface of the bathroom television 3, and both incline. Further, a recess 33 was formed so that the tool could reach the screw 4 when the screw 4 was tightened. Further, the cable 35 is drawn out from a substantially central portion on the back surface of the bathroom television 3, and the drawn portion is surrounded by a sponge-like sealing member 34.

  As shown in FIG. 4A, when the lower engaging portion 32 of the bathroom television 3 is engaged so as to be placed on the lower edge 11 and the bathroom television 3 is pressed against the base plate 1, the sealing member 34 is provided. Is moderately compressed. In this state, since the upper end 21 is not engaged with the upper engaging portion 31, if the hand is released from the bathroom television 3, the bathroom television 3 falls forward and falls.

  When the screw 4 is rotated clockwise in this state, the lower end 22 of the fixing bracket 2 screwed to the screw 4 is pulled downward, and as a result, the fixing bracket 2 slides downward. Then, the upper end 21 of the fixture 2 is engaged with the upper engaging portion 31 of the bathroom television 3 as shown in FIG. The bathroom television 3 is gripped from above and below by the upper end 21 of the fixing bracket 2 and the lower edge 11 of the base plate 1, and the bathroom television 3 is attached to the wall surface W. In addition, since it is not necessary to install a caulking agent around the bathroom TV 3 thereafter, the number of man-hours for the construction is reduced, and the caulking agent is not finally exposed to the outside, so that the finish is beautiful.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
