Description

  The present invention relates to a wall-mounted device that can be easily attached to a wall surface, such as a telephone, an interphone, and a modem device.

  In-house devices such as telephones, interphones, and modem devices are often installed on indoor walls for convenience. 2. Description of the Related Art Conventionally, various structures are known as a structure for fixing such a home device to a wall surface (see, for example, Patent Document 1 and Patent Document 2).

  According to the structure disclosed in Patent Document 1, the head insertion / removal hole having a diameter larger than the diameter of the head, into which the head of the wood screw fixed to the wall can be inserted / removed, and the shaft portion of the wood screw are relative to each other. A so-called daruma-shaped mounting hole made up of a hooking hole having a movable hole width is formed in two places on the back side case of the device so as to be vertically separated. And it was set as the structure which hooked each attachment hole part on the head of the wood screw screwed in to the wall surface to the appropriate position, respectively.

  At this time, the head insertion / removal hole in the attachment hole portion is located at the lower end portion, and the latching hole is configured to extend upward from the head insertion / removal hole. Therefore, the wood screw acts in the direction of being caught in the retaining hole, and thus a stable mounting state of the device has been obtained.

  In addition, according to the structure disclosed in Patent Document 2, a plurality of mounting pieces having so-called daruma-shaped mounting holes similar to the above are mounted on the back side of the device so as to be rotatable within a range of 90 degrees, and each mounting hole is formed. It was designed to be hooked and attached to the head of a wood screw screwed to the wall surface as appropriate. Then, by changing the angle of each mounting piece, the mounting posture of the device can be selectively changed to a vertical posture or a horizontal posture as necessary. In this case as well, a stable mounting state of the device was obtained as described above.

JP-A-8-237343 JP-A-8-008543

  However, according to the above-described structure disclosed in Patent Document 1, when the device is to be fixed by being rotated by 90 degrees, the mounting hole portion of the dharma type faces in the horizontal direction, so that a stable mounting state due to gravity cannot be expected. There was a problem.

  Further, according to the structure disclosed in Patent Document 2, each mounting piece is configured to be selectively fixable within a range of 90 degrees from each other, so that the device can be mounted in a vertical posture and a horizontal posture. However, there is a problem that it is necessary to adjust each mounting piece during the installation of the equipment.

  Therefore, as shown in FIG. 11, the center line L of the retaining hole 2a in each mounting hole 2 formed in the back surface side case portion 1 of the device so as to be separated in the vertical direction along the gravity direction is the gravity direction. It is conceivable that they are formed at a predetermined angle (for example, 45 degrees) in the same direction with respect to G (reference example).

  In this case, by selectively setting the upper side or the right side of the back side case portion 1 shown in FIG. 11 as the upper side, the mounting posture of the device can be stably mounted in two directions. In the figure, reference numeral 3a denotes a shaft portion of the mounting screw 3 fixed to the wall surface.

  However, in the installation work of the device, when the interval between the mounting screws 3 deviates from the determined dimension, there arises a new problem that the device is mounted with an inclination. For example, when the distance between the upper and lower mounting screws 3 is larger than the determined dimension, as shown in FIG. 12, the mounting screws 3 are formed on the tops of the retaining holes 2 a in the upper mounting holes 2. In the lower mounting hole 2, the engagement portion of the mounting screw 3 extends downward from the top of the latching hole 2 a in the longitudinal direction of the latching hole 2 a. Move. For this reason, the device is mounted in an inclined state in which the device is rotated counterclockwise around the upper mounting screw 3.

  Further, when the distance between the upper and lower mounting screws 3 is smaller than the determined dimension, as shown in FIG. 13, the mounting screws are formed at the tops of the latching holes 2a in the lower mounting hole 2. 3 is engaged, but in the upper mounting hole 2, the engagement portion of the mounting screw 3 extends from the top of the latching hole 2 a to the lower side in the longitudinal direction of the latching hole 2 a because the interval is reduced. Move. For this reason, the device is attached in an inclined state in which the device is rotated clockwise around the lower attachment screw 3.

  Therefore, the present invention has a simple structure, and allows the device to be selectively mounted in the vertical orientation or the horizontal orientation, and reduces the amount of inclination in the attachment state even when the distance between the upper and lower fixing members has an error. It aims at providing the wall hanging apparatus which aimed at effectively.

  The wall-mounted device according to claim 1 according to the present invention is a straight line having a hole width in which a shaft portion of a fixing member fixed to a wall surface is relatively movable and a head provided at an end portion of the shaft portion cannot pass. Mounting holes, each of which is formed at the lower end of the hooking hole and includes a head insertion / removal hole in which the head can be freely inserted / removed, are separated from each other in the vertical direction on the back surface of the device. In the wall-mounted device that is mounted by hooking each mounting hole to the corresponding fixing member, the center lines of the respective locking holes in both mounting holes are the same angle in the same direction with respect to the direction of gravity. If the hook hole is inclined to the right with respect to the head insertion / removal hole, the upper mounting hole is arranged on the right side of the back of the device and the lower mounting hole is the device. When it is arranged on the left side of the back and the retaining hole is inclined upward to the head insertion / removal hole The mounting hole of the lower side is disposed to the right of the back instrument with the upper mounting holes are arranged to the left of the back surface equipment.

  According to the wall-hanging device of the first aspect of the present invention, the center lines of the retaining holes in both the mounting holes are formed to be inclined at the same angle in the same direction with respect to the direction of gravity, and the head insertion / removal hole When the hooking hole is inclined upward to the right, the upper mounting hole is arranged on the right side of the back of the device and the lower mounting hole is arranged on the left of the back of the device. In the case where the latching hole is inclined upward to the left, the upper mounting hole portion is arranged on the left side of the device back surface and the lower mounting hole portion is arranged on the right side of the device back surface. In addition, due to the latching holes inclined at the same angle, there is an advantage that the device can be selectively and stably attached in the vertical posture or the horizontal posture, and the structure thereof is also simple.

  When the interval between the fixing members fixed to the wall surface is larger or smaller than the determined dimension, as described above, the device is slightly rotated counterclockwise or clockwise and inclined. Will be attached. However, the amount of inclination of the device due to this rotation is proportional to the tangent of the angle formed by the straight line connecting the predetermined positions of both mounting hole portions and the center line of each of the hooking holes formed at an inclination. The angle formed by the straight line connecting both mounting holes and the center line of each latching hole is smaller than when both mounting holes are vertically separated in the direction of gravity as shown in FIG. Here, the amount of inclination by which the device rotates is reduced by the amount of the angle formed, and the amount of inclination in the mounted state of the device is effectively reduced even when the distance between the upper and lower fixing members has an error. be able to.

<Embodiment 1>
Hereinafter, Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 shows a back surface side case portion 10a of a wall hanging device 10, and FIG. 2 shows a wall surface 14 by a mounting screw 12 as a fixing member. Sectional drawing of the attachment state fixed to is shown.

  The wall-mounted device 10 has a case structure having a substantially rectangular back surface whose one side is relatively longer than the other side, and components and the like according to the application of the wall-mounted device 10 are accommodated therein.

  Mounting holes 16 are formed in two places on the back side case portion 10a of the wall-mounted device 10. As shown in FIG. 1 when viewed from the back side of the wall-mounted device 10, each mounting hole 16 is located at the lower end and a circular head insertion / removal hole 16 a into which the head 12 a of the mounting screw 12 can be inserted and removed. Are respectively formed, and extending in the radial direction passing through the center in an upwardly inclined manner from the head insertion / removal hole 16a, are respectively formed with retaining holes 16b, which are so-called daruma-shaped.

  Each retaining hole 16b is formed in a straight line having a hole width through which the head portion 12a of the mounting screw 12 cannot pass and the shaft portion 12b connected to the head portion 12a is relatively movable. The center lines L of the respective latching holes 16b are structured to be inclined at the same angle in the same direction with respect to the gravity direction G, 45 degrees in the present embodiment, and the upper mounting holes 16 are formed on the back side case. The lower mounting hole 16 is disposed on the left side of the back surface side case portion 10a, and is disposed on the diagonal side. That is, the wall-mounted device 10 is structured to be spaced as much as possible in the vertical direction along the long side so that the mounting state of the wall-mounted device 10 is stabilized.

  At this time, the upper mounting hole portion 16 is arranged as far as possible to the right, the lower mounting hole portion 16 is arranged as far as possible to the left, and a straight line S connecting the corresponding predetermined positions of both the mounting hole portions 16 and the latching hole. The angle θ formed with the center line L in 16b is arranged to be as small as possible.

  Next, a procedure for attaching the wall hanging device 10 to the wall surface 14 will be described.

  First, the two mounting screws 12 are screwed in advance into the wall surface 14 to which the wall-mounted device 10 is to be attached in correspondence with the positions of the mounting hole portions 16 of the back side case portion 10a. At this time, the attachment screw 12 is screwed to a position where a space slightly larger than the thickness of the back surface side case portion 10a is provided between the surface of the wall surface 14 and the head portion 12a of the attachment screw 12.

  Next, if the head insertion / removal holes 16a in the respective mounting hole portions 16 of the back side case portion 10a are respectively pressed against the head portions 12a of the respective mounting screws 12 fixed to the wall surface 14, each head 12a is It is inserted into the back side case portion 10a through the head insertion / removal hole 16a.

  In this state, if the wall hanging device 10 is moved in the direction opposite to the extending direction of the hooking hole 16b, the shaft portion 12b of the mounting screw 12 is relatively moved along the hooking hole 16b, as shown in FIG. Thus, the state in which each shaft portion 12b is in contact with the upper end portion of the retaining hole 16b is obtained. If the hand is released in this state, the head 12a of each mounting screw 12 is hooked to the back side case portion 10a at the peripheral edge of the hooking hole 16b in each mounting hole 16 in a retaining manner. 10 is fixed in the mounted state hooked on the mounting screw 12. At this time, since it is hooked in the direction in which gravity acts, the mounting state is also stabilized.

  Further, in the above case, the wall-mounted device 10 is illustrated in a state where it is attached in a vertical orientation as shown in FIG. 1, but it can be similarly attached in a horizontal orientation with the right side portion of FIG. The posture can be selectively changed.

  The present embodiment is configured as described above, and since the latching holes 16b in the mounting hole portion 16 are both inclined at the same angle in the same direction, the wall-hanging device 10 is in the vertical orientation or the horizontal orientation. It can be selectively and stably attached. And the structure can also be provided by the simple structure which formed the latching hole 16b inclining.

  In particular, since the inclination angle of the center line of the retaining hole 16b is 45 degrees, the same stability is obtained whether the wall-mounted device 10 is mounted in the vertical orientation or in the horizontal orientation. There is an advantage that can be installed with.

  Further, in the installation work of the wall hanging device 10, when the interval between the mounting screws 12 deviates from the determined size, for example, as shown in FIG. 3, the one where the interval between the mounting screws 12 is larger than the determined size. When the shaft portion 12b of the mounting screw 12 is engaged with the top of the latching hole 16b in the upper mounting hole portion 16, the lower mounting hole portion 16 has an increased interval. The engaging portion of the mounting screw 12 moves from the top of the latching hole 16b to the lower side in the longitudinal direction of the latching hole 16b. Therefore, the wall-mounted device 10 is mounted in an inclined state in which the wall-mounted device 10 is slightly rotated counterclockwise around the upper mounting screw 12.

  On the other hand, as shown in FIG. 4, when the interval between the mounting screws 12 is shifted to be smaller than the determined dimension, the mounting screws 12 are placed on the tops of the latching holes 16 b in the lower mounting hole 16. In the upper mounting hole 16, the engagement portion of the mounting screw 12 extends from the top of the latching hole 16b to the lower side in the longitudinal direction of the latching hole 16b. Moving. Therefore, the wall-mounted device 10 is mounted in an inclined state in which the wall-mounted device 10 is slightly rotated clockwise about the lower mounting screw 12.

  However, the amount of inclination of the wall-hanging device 10 due to this rotation is proportional to the tangent of the angle θ formed by the straight line S connecting both the mounting holes 16 and the center line L of each of the hooking holes 16b formed to be inclined. Compared with the case where both mounting hole portions 2 are vertically separated along the direction of gravity G as in the above-mentioned reference example, the straight line S connecting both mounting hole portions 16 and the center line L of each latching hole 16b. Even when the angle θ between the upper and lower mounting screws 12 has an error, the amount of inclination by which the device 10 rotates is reduced by the amount the angle θ formed becomes smaller. The amount of inclination of the mounting state of the device 10 can be effectively reduced.

  In the above-described embodiment, the structure is shown in which the latching holes 16b in the mounting hole portion 16 are each formed to be inclined upward to the right. However, the latching holes 16b in the mounting hole portion 16 are respectively formed to be inclined upward to the left. It is good also as a structure to do. In this case, the upper mounting hole 16 may be disposed on the left side of the back surface side case portion 10a, and the lower mounting hole portion 16 may be disposed on the right side of the back surface side case portion 10a, and the same effect as described above can be obtained.
