Description

Technical Field

[0001] The present invention relates to a wiring device mounting frame for a toggle switch and a toggle switch device provided with the wiring device mounting frame.

Background Art

[0002] A toggle switch device is a switch device having a structure in which an electric circuit is switched by tilting a knob-shaped operation lever of a toggle switch in either the up or down direction or in either the left or right direction. The toggle switch device makes a clicking sound during ON / OFF operation, and the feeling of being operated is preferred. In addition, the operation portion protruding in a rod shape creates a retro feeling and is popular among not only the elderly but also the younger generation. In particular, a toggle switch device using a decorative plate made of ceramics such as ceramics has a high retro feeling and meets the needs of consumers.

[0003] Currently, in a toggle switch device using a ceramic decorative plate, a rod-shaped operation portion of the toggle switch is protruded outward through a switch protruding hole formed in the decorative plate, and the toggle switch is disposed on the back surface of the decorative plate by tightening and fixing from the outside of the decorative plate via a nut. And it was fixed by screwing into a screw hole of a box arranged on the wall surface side through a screw hole formed in the decorative plate.

[0004] Therefore, the screw heads of the screws for fixing the decorative plate were directly visible to consumers on the surface of the decorative plate of the toggle switch device. The inventors of the present invention have been intensively researching to make the toggle switch have a simpler and more refined design.

[0005] Although it is not a toggle switch, in the switch device disclosed in Patent Document 1, in the decorative plate and the fixed frame disposed on the wall surface side, by providing a locking / detaching protrusion and a locking convex portion respectively, the decorative plate is fixed so that the fixing method is difficult to be seen from the outside.

[0006] However, both the decorative plate and the fixed frame disclosed in Patent Document 1 are made of metal and can be configured to be lockable / detachable by utilizing their elasticity. It does not use a decorative plate made of porcelain as required by consumers and does not prevent the fixing method from being directly visible from the outside, and nothing has been provided that can meet the needs of consumers at all.

Embodiment for Carrying Out the Invention

[0017] Hereinafter, an embodiment of a wiring device mounting frame for a toggle switch device of the present invention and a toggle switch device using the wiring device mounting frame will be described. Note that this embodiment is merely an embodiment of the present invention and should not be construed as being limited in any way, and design changes can be appropriately made within the scope of the present invention.

[0018] FIGS. 1 and 2 show an embodiment of a toggle switch device 1 using a wiring device mounting frame 25 for a toggle switch device of the present invention.

[0019] The toggle switch device 1 includes, for example, a case body 3 fixedly attached to the indoor wall surface side, a wiring device mounting frame 25 fixedly attached with a toggle switch 13 and fixedly attached to the case body 3, and a decorative plate (cover member) 21 fixedly attached via the toggle switch 13. The toggle switch 13 includes a rectangular box-shaped main body 15, a cylindrical outer screw portion 17 protruding from the upper surface of the main body 15 and protruding from a switch mounting hole 27 of the wiring device mounting frame 25, and a rod-shaped operation portion 19 protruding outward from the inside of the cylinder of the outer screw portion 17. It has a well-known general configuration for performing ON / OFF operation by switching the operation portion 19 in the vertical or horizontal direction, and is not particularly limited to the illustrated form and can be arbitrarily designed and changed.

[0020] The case body 3 is composed of a rectangular plate-shaped bottom plate 5 and four side plates 7 formed by rising from each side of the bottom plate 5, and is configured in a box shape with an open upper surface. The side plates 7 are composed of two long side portions 7a, 7a and two short side portions 7b, 7b. Mounting frame fixing portions 9, 9 protruding horizontally from opposite positions are provided on the inner surfaces of the upper ends of the two short side portions 7b, 7b, respectively. The mounting frame fixing portion 9 has screw holes 11 formed in its tip region.

[0021] Further, the case body 3 is, for example, embedded and fixed in a wall surface (not shown) with the released upper surface area facing outward, or attached and fixed on the surface of the wall surface. Note that the case body 3 is not limited to the illustrated form and can be designed and changed within the scope of the present invention. Also, the mounting position is not limited.

[0022] The decorative plate 21 is made of ceramics (porcelain), for example, and is formed in a rectangular plate shape in a front view with a size that covers the released upper surface of the case body 3. At a position facing the switch mounting hole 27 provided in the wiring device mounting frame 25 described later, a circular switch protruding hole 23 is provided in a front view.

[0023] In the present embodiment, three switch protruding holes 23 are provided in a straight line in the length direction L1 of the decorative plate 21. That is, three toggle switches 13 are configured to be arranged vertically side by side. In the present embodiment, one toggle switch is arranged through the central switch mounting hole 23a. The decorative plate 21 is not limited to the present embodiment and can be designed and changed within the scope of the present invention. Although the present invention is most suitable for a material such as ceramics in the present embodiment, in which it is difficult to project a locking piece or the like that can be locked using elasticity, the material is not particularly limited, such as wood or metal.

[0024] The wiring device mounting frame for the toggle switch (hereinafter, also simply referred to as the "wiring device mounting frame") 25 adopts the form shown in FIGS. 3 to 8, for example, in the present embodiment.

[0025] The wiring device mounting frame 25 is made of, for example, a steel plate, and is a long rectangular plate shape that is shorter in the length direction L1 and narrower in the width direction W1 than the decorative plate 21 (see FIGS. 1 and 2).

[0026] In the central region in the width direction W1 of the wiring device mounting frame 25, three switch mounting holes 27, 27, 27 for mounting and fixing the toggle switch 13 are formed on the same straight line in the length direction L1. In the present embodiment, the central switch mounting hole 27a in the length direction L1 of the wiring device mounting frame 25 is a perfect circle, and the other two switch mounting holes 27b, 27b are formed in an ellipse in the length direction L1 of the wiring device mounting frame 25 (see FIGS. 3 and 4). The reason for adopting such a configuration is to make it possible to adjust the mounting position with the two upper and lower elliptical switch mounting holes 27b so that the main body portions 15 of the respective toggle switches 13 do not interfere with each other. The toggle switch 13 positions the main body portion 15 on the back surface 25b side of the wiring device mounting frame 25, and projects the cylindrical outer surface screw portion 17 and the operation portion 19 from the switch mounting hole 27a to the front surface 25a side of the wiring device mounting frame 25, and is fastened and fixed via a nut (for fixing the switch) 20 and disposed integrally (see FIGS. 1 and 2).

[0027] Further, screw holes 29, 29 for screwing and fixing to the screw holes (wall surface side) 11, 11 of the case body 3 are formed near both ends in the length direction L1 of the wiring device mounting frame 25 so as to sandwich the switch mounting holes 27 (27a, 27b, 27b) in the length direction L1 (see FIGS. 1, 3, and 4).

[0028] The screw holes 29 are long ellipses in the width direction W1 of the wiring device mounting frame 25, and are formed as deformed ellipses in which the regions 29a, 29a of the opposing sides of the respective screw holes 29, 29 are slightly recessed in the respective hole directions (see FIGS. 3 and 4). The reason for adopting such a configuration is to facilitate the mounting workability by enabling fine adjustment of the mounting position in the length direction L1 of the mounting frame when the wiring device mounting frame 25 is screwed and fixed to the case body 3.

[0029] The periphery of the screw hole 29 is provided with a first bending prevention portion 31 that is recessed from the decorative plate facing surface (front surface) 25a direction to the back surface 25b direction of the wiring device mounting frame 25 (see FIGS. 7 and 8).

[0030] The first bending prevention portion 31 forms an elliptical protruding region 33 on the back surface 25b by recessing the periphery of the screw hole 29 from the decorative plate facing surface (front surface) 25a toward the back surface 25b, so that when the decorative plate 21 is fastened and fixed with a nut (for fixing the decorative plate) 22 from the outer surface (front surface) 21a of the decorative plate 21 via the toggle switch 13, the pressure is dispersed to achieve surface strengthening, and the bending of the wiring device mounting frame 25 can be prevented. The depth of the recess of the first bending prevention portion 31 is arbitrary, and it is preferably set to such an extent that there is no adverse effect on the accommodation of wiring or the like inside the case body 3.

[0031] In the direction orthogonal to the length direction L1 of the wiring device mounting frame 25 (width direction W1 of the wiring device mounting frame 25), on both the left and right sides adjacent to each screw hole 29, there are provided second bending prevention portions 35 protruding from the back surface 25b of the wiring device mounting frame 25 toward the front surface (decorative plate facing surface) 25a (see FIGS. 1, 3 to 6, and FIGS. 8).

[0032] The second bending prevention portion 35 is formed, for example, in the present embodiment, by bead processing, on the front surface of the wiring device mounting frame 25, as a narrow-width elliptical ridge in its length direction. Thereby, when the decorative plate 21 is fastened and fixed with a nut (for fixing the decorative plate) 22 from the front surface 21a of the decorative plate 21 via the toggle switch 13, the pressure is dispersed together with the first bending prevention portion 31 to achieve surface strengthening, and further bending of the wiring device mounting frame 25 can be prevented. Also, the second bending prevention portion 35 is formed so as to provide a gap G1 between it and the screw hole 29 and be located outside in the width direction W1 of the wiring device mounting frame 25 than the outer contour 41 position of the third bending prevention portion 37 to be described later (see FIG. 3).

[0033] Further, the protruding height of the second bending prevention portion 35 is preferably set such that when the decorative plate 21 is tightened and fixed, it protrudes from the back surface 21a of the decorative plate 21 and does not inhibit tightening. In the present embodiment, it is designed to be lower than the height of the nut (for fixing the switch) 20 that fixes the toggle switch 13 by tightening and fixing to the outer screw portion 17 of the toggle switch 13 on the surface 25a side of the wiring device mounting frame 25 (see Fig. 2).

[0034] Around the switch mounting holes 27, 27, 27, a third bending prevention portion 37 that is recessed toward the back surface 25b direction of the wiring device mounting frame 25 is provided. In the present embodiment, the third bending prevention portion 37 is recessed in a long shape so as to surround the entire three switch mounting holes 27, 27, 27 (see Figs. 1, 3, and 4).

[0035] The third bending prevention portion 37 is formed, for example, by bead processing, as a wide and long elliptical shallow concave depression on the surface 25a side of the wiring device mounting frame 25. Also, when viewed from the back surface 25b side, a wide and long elliptical outer contour (protruding region) 41 is formed so as to surround the switch mounting holes 27, 27, 27. Thereby, when the decorative plate 21 is tightened and fixed with the nut (for fixing the decorative plate) 22 from the surface 21a of the decorative plate 21 via the toggle switch 13, the third bending prevention portion 37, together with the first bending prevention portion 31 and the second bending prevention portion 35, disperses the pressure to strengthen the surface and can prevent the bending of the wiring device mounting frame 25. The depth of the recess of the third bending prevention portion 37 is arbitrary, and it is preferably set such that there is no adverse effect on the accommodation of wiring and the like inside the case body 3.

[0036] On the left and right side edges in the length direction L1 of the wiring device mounting frame 25, fourth bending prevention portions 43, 43 that are continuously bent and formed from the surface (the surface facing the decorative plate) 25a are provided (see Figs. 1, 2, and 4 to 8).

[0037] The fourth bending prevention part 43 is formed by bending (bending process) into a substantially rectangular plate shape continuously at a substantially right angle toward the back surface (rear surface) 25b of the wiring device mounting frame 25 on both side edges excluding both end regions 25c, 25c in the length direction L1 of the wiring device mounting frame 25. The protruding length (width) in the back direction of the fourth bending prevention part 43 is not particularly limited and can be changed in design within the scope of the present invention, but it is preferably set to such an extent that there is no adverse effect on the accommodation of wirings or the like inside the case body 3. Thereby, when the decorative plate 21 is fastened and fixed with a nut (for fixing the decorative plate) 22 from the surface 21a of the decorative plate 21 via the toggle switch 13, the fourth bending prevention part 43, together with the first to third bending prevention parts 31 to 37, can disperse the pressure to strengthen the surface and prevent the bending of the wiring device mounting frame 25.

[0038] The reason why the fourth bending prevention part 43 is provided by bending toward the back surface 25b of the wiring device mounting frame 25 is as follows. When bending is performed in the direction of the surface 25a of the wiring device mounting frame 25, that is, in the direction of the back surface 21b of the decorative plate 21, a space corresponding to the height of the fourth bending prevention part 43 is formed between the surface 25a of the wiring device mounting frame 25 and the back surface 21b of the decorative plate 21. As a result, the tightening range of the nut (for fixing the decorative plate) 22 to the outer screw part 17 on the outer surface of the toggle switch 13 becomes short, and there is a risk that the tightening force will decrease. Alternatively, there is also a risk of inconvenience such that the outer screw part 17 does not protrude outside the decorative plate 21 and cannot be fastened and fixed via the nut (for fixing the decorative plate) 22.

[0039] By bending in the direction of the back surface 25b of the wiring device mounting frame 25 as in this embodiment to provide the fourth bending prevention portions 43, 43, the gap between the decorative plate 21 and the wiring device mounting frame 25 becomes smaller. Therefore, when passing the outer screw portion 17 of the toggle switch 13 through the switch protruding hole 23 of the decorative plate 21 and then fastening and fixing the outer screw portion 17 of the toggle switch 13 with a nut (for fixing the decorative plate) 22 from the surface 21a side of the decorative plate 21, the outer screw portion 17 can sufficiently protrude outward of the decorative plate 21, so there is no risk that the fastening and fixing area will become short. Also, since the area protruding to the surface 25a side of the wiring device mounting frame 25 is small, the gap between the decorative plate 21 and the wiring device mounting frame 25 can be made smaller. When fastening and fixing, there is no risk that the toggle switch 13 will be pushed too much, and as a result, the wiring device mounting frame 25 that fixes the toggle switch 13 will also be attracted in the direction of the decorative plate 21 through that space and bent.

[0040] According to this embodiment, the toggle switch 13 is detachably attached to the wiring device mounting frame 25 by positioning its main body portion 15 on the back surface 25b side of the wiring device mounting frame 25, protruding the outer screw portion 17 and the operation portion 19 to the surface 25a side from the central switch mounting hole 27a, and fastening and fixing through a nut (for fixing the switch) 20. Then, the wiring device mounting frame 25 with the toggle switch 13 attached is integrally disposed on the wall surface side by screwing and fixing it to the screw holes 11, 11 of the case body 3 disposed on the wall surface side through the screw holes 29, 29. Next, the outer screw portion 17 and the operation portion 19 of the toggle switch 13 are protruded outward of the decorative plate 21 through the switch protruding hole 23 (23a) of the decorative plate 21, and are detachably fastened and fixed from the surface 21a side of the decorative plate 21 through a nut (for fixing the decorative plate) 22. As a result, the decorative plate 21 can be attached integrally with the wiring fixture mounting frame 25 for the toggle switch and the case body 3 without using a dedicated mounting screw or the like, and no screw head or the like is exposed on the surface side of the decorative plate as in the conventional toggle switch device. Therefore, the entire toggle switch device has a simple and sophisticated design and can meet the needs of consumers.

[0041] Note that the switch mounting holes 27 provided in the wiring fixture mounting frame 25 may be plural or singular. Further, the wiring fixture mounting frame 25 is not limited to a steel plate and may be made of other metals such as steel materials and is within the scope of the present invention.
