[0013] The wall mounting device 1 is a device for attaching an arbitrary wall-embedded object (not shown) to be embedded in a wall (ceiling is also possible) to the opening 101 of the wall material 100 (see FIG. 1). As the wall-embedded object, for example, a wall-embedded wireless LAN (Local Area Network) router, a wall-embedded intercom, a wall-embedded outlet, a wall-embedded gas supply device, a wall-embedded induction lamp, a ceiling-embedded air conditioner, etc. can be used, and a wall-embedded device that contributes to miniaturization can be used. The wall mounting device 1 has a spring mechanism including shafts 21 to 24, stopper members 31, 32, pressure plates 40, 50, and compression springs 61 to 64. The wall mounting device 1 includes a front plate 10, shafts 21 to 24, stopper members 31, 32, pressure plates 40, 50, and compression springs 61 to 64.

[0014] The front plate 10 is a plate-shaped plate that is disposed on the front surface 100a of the wall material 100 when the wall mounting device 1 is attached to the opening 101 (a rectangular opening in FIG. 1) of the wall material 100 (see FIG. 1). The front plate 10 has an open window portion 15 at the central portion for disposing an object to be embedded in the wall (not shown). The window portion 15 has recesses 15a and 15b for attaching an object to be embedded in the wall (not shown). The front plate 10 has holes 11 to 14 (for example, screw holes, through holes, key holes, etc.) for attaching an object to be embedded in the wall (not shown). Note that the recesses 15a and 15b and the holes 11 to 14 may not be provided if they are not necessary. The front plate 10 can be configured to be rectangular when viewed from the front. The portion of the back surface of the front plate 10 near the outer periphery is in contact (pressure contact by the pressing force of the compression springs 61 to 64) with the peripheral edge of the opening 101 on the front surface 100a of the wall material 100. The portion of the back surface of the front plate 10 near the window portion 15 is disposed so as to overlap the opening 101 when viewed from the front side. One end of a plurality of (four in FIG. 1) shafts 21 to 24 extending in the front-rear direction is fixed to the portion of the back surface of the front plate 10 near the window portion 15 in the vicinity of the end surface of the opening 101 of the wall material 100.

[0015] Shafts 21 to 24 are shaft-shaped members (see Fig. 1). The shafts 21 to 24 are arranged to extend in the front-rear direction. One end of each of the shafts 21 to 24 is fixed to the back surface of the front plate 10. When the wall mounting device 1 is inserted into the opening 101 of the wall material 100 (see Fig. 2), the shafts 21 to 24 are arranged near the end face of the opening 101 of the wall material 100 so as not to contact the wall material 100. The shafts 21 to 24 are inserted through the opening 101 of the wall material 100. Corresponding stopper members 31 and 32 are fixed to the other ends of the shafts 21 to 24. In Fig. 1, the stopper member 31 is fixed to each of the other ends of the shafts 21 and 22, and the stopper member 32 is fixed to each of the other ends of the shafts 23 and 24. Compression springs 61 to 64 are arranged on the outer circumferences of the shafts 21 to 24. The shafts 21 to 24 are inserted through the slide holes 41, 42, 51, and 52 of the corresponding pressure plates 40 and 50 on the side closer to the front plate 10 than the compression springs 61 to 64. The shafts 21 and 22 inserted through the slide holes 41 and 42 of the pressure plate 40 are configured not to overlap with the shafts 23 and 24 inserted through the slide holes 51 and 52 of the pressure plate 50.

[0016] The stopper members 31 and 32 are members that lock (support) the other ends of the compression springs 61 to 64 arranged on the outer circumferences of the shafts 21 to 24 (see Fig. 1). The stopper members 31 and 32 are fixed to the other ends of the corresponding shafts 21 to 24. In Fig. 1, the stopper member 31 is fixed to each of the other ends of the shafts 21 and 22, and the stopper member 32 is fixed to each of the other ends of the shafts 23 and 24. When the wall mounting device 1 is inserted into the opening 101 of the wall material 100 (see Fig. 2), the stopper members 31 and 32 are arranged near the end face of the opening 101 of the wall material 100 so as not to contact the wall material 100. Although there are two stopper members 31 and 32 in Fig. 1, the configuration may be such that each of the other ends of the shafts 21 to 24 is fixed to one stopper member. Also, although the stopper members 31 and 32 are configured to bridge between the corresponding shafts 21 to 24 in Fig. 1, they may be provided individually for each of the shafts 21 to 24 without bridging, and they do not have to be plate-shaped.

[0017] The pressure plates 40 and 50 are members for pressing the peripheral edge of the opening 101 on the back surface 100b of the wall material 100 against the front plate 10 side (see Fig. 1). There are a plurality of pressure plates 40 and 50. The pressure plates 40 and 50 each have a plurality of through slide holes 41, 42, 51, and 52. The pressure plates 40 and 50 are movable in the front-rear direction between the front plate 10 and the compression springs 61 to 64. The corresponding shafts 21 to 24 are inserted into the slide holes 41, 42, 51, and 52. The slide holes 41, 42, 51, and 52 serve as holes for sliding the pressure plates 40 and 50 outward (both left and right outer sides in Fig. 1) with respect to the shafts 21 to 24. The slide holes 41, 42, 51, and 52 guide the movement of the pressure plates 40 and 50 with respect to the shafts 21 to 24. The guiding direction by the slide holes 41 and 42 of the pressure plate 40 is configured to be in the opposite direction to the guiding direction by the slide holes 51 and 52 of the pressure plate 50. The slide holes 41, 42, 51, and 52 are configured to guide the pressure plates 40 and 50 to slide in the first direction (the left-right direction in Fig. 1, or the up-down direction is also possible) with respect to the shafts 21 to 24, so as to guide from a state where the peripheral edge of the opening 101 in the wall material 100 is not sandwiched between the front plate 10 and the pressure plates 40 and 50 to a state where it is sandwiched. That is, when the wall mounting device 1 is inserted into the opening 101 of the wall material 100 in a state where the pressure plates 40 and 50 are closed inward (see Fig. 2), the pressure plates 40 and 50 are configured not to contact the wall material 100 (see Fig. 5(A)). The pressure plates 40 and 50 are configured to contact the peripheral edge of the opening 101 on the back surface 100b of the wall material 100 in a state where the wall mounting device 1 is inserted into the opening 101 of the wall material 100 and opened outward (see Fig. 5(B)). The slide holes 41, 42, 51, and 52 have recesses 41a, 42a, 51a, and 52a for inserting the shafts 21 to 24 from the radial direction.The recesses 41a, 42a, 51a, and 52a are configured such that when the peripheral edge of the opening 101 in the wall member 100 is sandwiched between the front plate 10 and the pressure plates 40 and 50, the pressure plates 40 and 50 can be slid in the second direction (a direction different from the first direction (e.g., a perpendicular direction; in FIG. 1, it can be the vertical or horizontal direction)), so that the shafts 21 to 24 can be inserted. That is, the recessed directions of the recesses 41a, 42a, 51a, and 52a are set to be different from the sliding direction for opening and closing the slide holes 41, 42, 51, and 52 (a direction perpendicular in FIG. 1). The recesses 41a, 42a, 51a, and 52a are configured such that the shafts 21 to 24 can be press-fitted or inserted. When the pressure plates 40 and 50 are opened outward, the shafts 21 to 24 corresponding to the recesses 41a, 42a, 51a, and 52a are inserted (press-fitted, inserted), thereby restricting the movement of the shafts 21 to 24 so that the pressure plates 40 and 50 do not close, and suppressing the inclination of the pressure plates 40 and 50 with respect to the back surface 100b of the wall member 100.

[0018] The compression springs 61 to 64 are elastic members that receive a compression load (see FIG. 1). The number of the compression springs 61 to 64 is the same as the number of the shafts 21 to 24. The compression springs 61 to 64 are arranged on the outer peripheries of the corresponding shafts 21 to 24. The other ends of the compression springs 61 to 64 are restricted from moving in the back direction (rear direction) by the corresponding stopper members 31 and 32. One ends of the compression springs 61 to 64 press the corresponding pressure plates 40 and 50 toward the front plate 10 when the wall member 100 is sandwiched between the front plate 10 and the pressure plates 40 and 50. The compression springs 61 to 64 are in a compressed state between the corresponding stopper members 31 and 32 and the pressure plates 40 and 50 when the wall member 100 is sandwiched between the front plate 10 and the pressure plates 40 and 50.

[0019] The wall mounting device 1 configured as described above can be mounted on the opening 101 of the wall member 100 as follows.

[0020] That is, as shown in FIG. 2, with the pressure plates 40 and 50 closed, the stopper members 31 and 32, the shafts 21 to 24, the compression springs 61 to 64, and the pressure plates 40 and 50 of the wall mounting device 1 are inserted into the opening 101 from the front surface 100a side of the wall material 100, and the front plate 10 of the wall mounting device 1 is brought into contact with the front surface 100a of the wall material 100. As a result, as shown in FIGS. 3 and 4, a part of the wall mounting device 1 protrudes to the back surface 100b side of the wall material 100.

[0021] Next, while pressing the pressure plates 40 and 50 toward the stopper members 31 and 32 so that the compression springs 61 to 64 are compressed, the pressure plates 40 and 50 are slid as shown in FIGS. 5(A) to 5(B) so as to be in an open state on both left and right outer sides. As a result, a portion where the pressure plates 40 and 50 overlap the back surface 100b of the wall material 100 in the front-rear direction is formed, the pressure plates 40 and 50 are pressed toward the front plate 10 side by the compression springs 61 to 64, and the peripheral edge portion of the opening 101 in the wall material 100 is sandwiched between the front plate 10 and the pressure plates 40 and 50.

[0022] Finally, the pressure plates 40 and 50 are slid downward, and the shafts 21 to 24 are inserted (press-fitting or fitting is also possible) into the recesses 41a, 42a, 51a, and 52a of the pressure plates 40 and 50 as shown in FIGS. 6 and 7. As a result, the lateral movement of the pressure plates 40 and 50 is restricted, the inclination of the pressure plates 40 and 50 with respect to the back surface 100b of the wall material 100 is suppressed, the pressure plates 40 and 50 can be maintained in an open state, and the wall mounting device 1 can be fixed to the wall material 100.

[0023] According to Form 1, the wall mounting device 1 can be fixed to the opening 101 of the wall material 100 by a simple pressing operation and sliding operation of the pressure plates 40 and 50 of the wall mounting device 1. Therefore, even without tools or in a place with a narrow working space, the work can be carried out, which can contribute to improving the workability of installing the device.

[0024] Further, according to the first embodiment, since there is no handling of fixing tools such as screws and rivets, there is no need to worry about the dropping of the fixing tools, and the wall mounting device 1 can be attached to the wall material 100, thereby improving workability.

[0025] Also, according to the first embodiment, parts other than the shafts 21 to 24, the stopper members 31 and 32, and the compression springs 61 to 64 are not required for the front plate 10, so that cost reduction is possible.

[0026] Further, according to the first embodiment, there is no need to reach into the back surface 100b side of the wall material 100, and the attachment work of the wall mounting device 1 can be easily performed.

[0027] Furthermore, according to the first embodiment, since the pressure plates 40 and 50 are configured to be pushed out by the pressing force of the compression springs 61 to 64 in the compressed state, the movable range of the pressure plates 40 and 50 in the front-rear direction can be increased, and the wall mounting device 1 can be attached to the openings 101 of wall materials 100 having various thicknesses, thereby improving workability.

[0028] [Second Embodiment] The wall mounting device according to the second embodiment will be described with reference to the drawings. FIG. 8 is a partially enlarged cross-sectional view schematically showing a state in which a second example of the wall mounting device according to the present disclosure is inserted into an opening of a wall material, the pressure plate is opened, and the shaft is inserted into the recess.

[0029] Form 2 is a modification of Form 1, and a sheet member 70 is disposed between the pressure plate 40 and one end of the compression spring 61 (see Fig. 8). A sheet member similar to the sheet member 70 in Fig. 8 is also disposed at a location corresponding to between the pressure plate 40 and one end of the compression spring 62 in Fig. 1, between the pressure plate 50 and one end of the compression spring 63, and between the pressure plate 50 and one end of the compression spring 64. The sheet member 70 has a through hole 71 through which the shaft 21 is inserted. The sheet member 70 is preferably larger than the outer diameter of the compression spring 61. As the sheet member 70, for example, a resin washer, a metal washer, a disc spring, or the like can be used. The sheet member 70 may be formed in accordance with the shape of one end of the compression spring 61, or may be fixed (adhered, welded, fixed, etc.) to one end of the compression spring 61.

[0030] According to Form 2, similar to Form 1, it can contribute to improving the workability of attaching the device, and since the pressing force of the compression spring 61 is evenly transmitted to the portion of the pressure plate 40 around the shaft 21 via the sheet member 70, the inclination of the pressure plate 40 with respect to the back surface 100b of the wall member 100 can be suppressed.

[0031] [Form 3] The wall mounting device according to Form 3 will be described with reference to the drawings. Fig. 9 is a (A) partial cross-sectional view and a (B) partial cross-sectional view between Y - Y' in a state of being attached to a wall member, schematically showing the configuration of a third example of the wall mounting device according to the present disclosure.

[0032] The wall mounting device 1 is a device for attaching an arbitrary wall - embedded object (not shown) to be embedded in a wall to the opening 101 of the wall member 100. The wall mounting device 1 includes a front plate 10, a shaft 21, a compression spring 61, a pressure plate 40, and a stopper member 31.

The stopper member 31 is fixed to the other end of the shaft 21 and is configured to lock the other end of the compression spring 61. The slide hole 41 is configured to guide the pressure plate 40 to slide in a direction perpendicular to the front-rear direction with respect to the shaft 21, so that the peripheral edge of the opening 101 in the wall member 100 is sandwiched between the front plate 10 and the pressure plate 40 from a state where it is not sandwiched. The compression spring 61 is configured to press the pressure plate 40 toward the front plate 10 when the peripheral edge of the opening 101 in the wall member 100 is sandwiched between the front plate 10 and the pressure plate 40.

[0034] According to the third embodiment, the wall mounting device 1 can be fixed to the opening 101 of the wall member 100 by a simple pressing operation and sliding operation of the pressure plate 40 of the wall mounting device 1. Therefore, even in a place where there are no tools or the working space is narrow, the work can be carried out, which can contribute to improving the workability of installing the device.
