As a result, even when the operation handle 40 is enlarged, the exposed portion of the operation handle 40 exposed from the opening 52 of the plate frame B, which will be described later, does not increase too much, making the appearance better than in the related art. There is an advantage that can be.

In addition, as shown in FIG. 2, the operation handle 40 is formed in such a size that the projected image on the upper surface of the main body 1 (cover 1b) is formed to be substantially the same size as the upper surface of the main body 1. . In addition, at both ends in the longitudinal direction of the upper surface of the cover 1b, a supporting portion 14 is provided with a pair of locking rings 13 protruding from both ends of the outer surface. These hooks 13 are formed with an inclined surface 13a inclined outward from the top of the base 14 to the bottom.

It will be described, and then the plate frame (B) and front plate (C) constituting the switching device according to the present invention with the switch (A _1). In addition, the plate frame B and the exterior plate C are used for attaching the switch A ₁ to a mounting surface such as a wall surface. The rectangular frame-shaped plate frame main body 51 is integrally formed with a thermoplastic resin such as ABS resin (which may be a thermosetting resin having elasticity), and an operation handle of the switch A ₁ is formed at the center portion thereof. A rectangular opening 52 is formed to expose 40 to the front side. The belt-shaped fixed support part 54 and the movable support part 55 are formed in the peripheral edge back side of this opening part 52 so that mutually opposes along the longitudinal direction of the opening part 52. As shown in FIG. The movable support portion 55 is separated from the frame member 53b on one side of the pair of side frame members 53a and 53b along the longitudinal direction of the plate frame body 51, and is also connected to both ends thereof by the connecting portion 56. Is integrally connected to the side frame member 5Bb. Here, the synthetic resin which forms the plate frame body 51 including the movable support part 55 and the connection part 56 is a flexible material, and the movable support part 55 and the connection part (with respect to the plate frame body 51) 56 are free to bend, respectively.

In addition, the movable support part 55 is supported by the pair of narrow ribs 57 which are integrally extended from the side frame member 5Bb, and between the movable support part 55 and the side frame member 53b. The gap created by the rib 57 is divided into three portions (hereinafter, each portion is referred to as slits 58a to 58c) by the ribs 57. Among them, the outer ends of the slits 58a and 58c on both sides are bent toward the connecting portion 56. Moreover, since the movable support part 55 is easily bent in the site | part near each rib 57 of the side frame member 53b, the pair of long hole groove 59 is formed.

On the other hand, on the sides of the opening portion 52 of the fixed support portion 54 and the movable support portion 55, three pairs of engaging grooves 54a and 55a to which the locking ring 13 of the switch A ₁ is fixed are formed at equal pitches. have. Accordingly, by engaging the locking ring 13 of the switch A ₁ with the respective locking grooves 54a and 55a, the switch frame body 51 is switched to the plate frame body 51 with the operation handle 40 exposed from the opening 52. (A ₁ ) can be attached. Here, the front end portions of the fixed support portion 54 and the movable support portion 55 may engage the locking ring 13 of the switch A ₁ with the locking grooves 54a and 55a on the rear side of the plate frame body 51. At this time, in order to guide each locking ring 13 to the locking grooves 54a and 55a, guide portions 54b and 55b each having a tapered surface inclined outward are formed.

That is, as shown in Figure 6, after engaging the locking ring 13 of one side of the switch (A ₁ ) to the locking groove (54a) of the fixed support portion 4 of the plate frame (B), By pushing the switch A ₁ from the back side of the plate frame B to the front side while the side catching ring 13 is in contact with the guide portions 54b and 54b, the catching ring 13 is moved to the guide portion 54b,. a movable support portion (retaining ring (13, bend 5) in the plate frame (B) while being guided by the tapered surface of 55b)) walking on the engagement groove (54a, 55a) fit to the switch (a ₁₎ to the plate frame (B) Can be mounted. Here, since the operation handle 40 of the switch A ₁ is formed in the dimension in which the projected image on the upper surface of the main body 1 (cover 1b) is formed to be substantially the same size as the upper surface of the main body 1. The operation handle 40 is attached to the intermediate handle 30 so that the switch A ₁ is passed through the operation handle 40 on the back side through the opening 52 of the plate frame B in the state of the finished product. As described above, the switch A ₁ can be mounted to the plate frame B. As a result, when the operation handle is enlarged in order to improve the operability, the operation handle can be inserted into the opening 52 of the plate frame B, and after the switch is attached to the plate frame B, other operation handles are provided. Although the cumbersome work of attaching the slit may be necessary, the switch A ₁ in the present invention does not require such a cumbersome work, and thus there is an advantage that the construction work is easy.

In addition, the locking ring 13 is engaged with each of the locking grooves 54a and 55a between the base portion of the fixed support portion 54 and the movable support portion 55 and the end edge of the opening portion 52 of the plate frame body 51. Contact portions 54d and 55d are formed in contact with a part of the front surface side of the main body ₁ of the switch A _{1 in} a state in which the switch A ₁ is made. For this reason, when a force is applied to the main body ₁ of the switch A _{1 in} the front direction of the plate frame B in a state where it is attached to the plate frame B, it is the contact portion that the main body 1 moves to the front side. (54d. 55d). Similarly, when a force is applied to the main body _{1 of the} switch A _{1 in} the back direction of the plate frame B, the locking ring 13 and the engaging grooves 54a and 55a are in contact with each other. Can regulate movement In addition, the connecting portion 56 connecting the movable support portion 55 and the side frame member 53b of the plate frame body 51 is made thin by forming the outer ends of the slits 58a and 58c curved. When the strong support force from the front side to the back direction is applied to the main body _{1 of} (A ₁ ), since the movable support part 55 is bent so that it may fall to the opening part 52 side, the locking groove of the movable support part 55 ( The locking ring 13 of the switch A ₁ does not come off in 55a, and the dropping of the switch A ₁ from the plate frame B can be prevented.

In addition, the fixing support portion 54 is provided with a mechanism separation hole 54c passing from the front side of the plate frame body 51 between the engaging grooves 54a, so that the front end portion of the driver, the separation jig, or the like is separated from the mechanism. When inserted into the hole 54c, the main body 1 is pushed to the movable support 55 at the front end of the jig, and according to the principle of the lever, the movable support 55 can be bent with a small force, and the fixed support 54 ) can be separated from the locking groove (54a) and switches (a ₁₎ from the switch (a _1), the swivel hook (13) frame plate main body 51 to hang off the alignment of the side. In addition, a projection 16 having an inclined surface 16a inclined downward toward the outside protrudes from the lower portion between the catches 13 on both sides of the cover 1b of the switch A, as shown in FIG. The front end portion of the jig or the like inserted into the mechanism separation hole 54c is brought into contact with the projection 16 so that the operation of pulling out is easily performed.

By the way, a plate frame (B) is a three dogs, by the orthogonal to the longitudinal direction of the switch (A ₁₎ in the longitudinal direction of the opening 52 is to be mounted or three side-by-side, and these switches (A ₁₎ The dimension of is referred to as one module dimension. In addition, the pitch of each pair of engaging rings 13 protruding from both sides of the main body _{1 of the} switch A ₁ is also formed in the fixed support portion 54 and the movable support portion 55 of the plate frame main body 51. The pitch of the engaging grooves 54a and 55a is matched.

On the other hand, since each of the locking grooves 54a and 55a of the fixed support portion 54 and the movable support portion 55 is formed at six equal pitches, the switch frame A ₁ having one module size is provided with the plate frame body 51. The pair of catching rings 13 formed in the main body _{1 of the} switch A ₁ can be engaged with any of the catching grooves 54a and 55a when mounted on the main body _{1 of the} switch A ₁ . The mounting position of the switch A ₁ with respect to 52 can be arbitrarily selected from five.

By the way, the recessed part 61 is formed in the both-side member 60 facing the longitudinal direction of the plate frame main body 51, respectively. Each element 61 has a long hole 6 for inserting a box screw for mounting the plate frame B to a buried box (not shown), and the plate frame B is mounted directly on an installation surface such as a wall surface. The screw insertion hole 63 into which the screw is inserted is inserted, and the insertion member engaging hole 64 fixed by engaging an insertion member (not shown) used for mounting to a wall panel or the like forming the installation surface is formed.

In addition, four corners of the plate frame main body 51 are provided with external plate engaging holes 65 fixed by engaging the engaging projection 83 protruding from the back of the plate main body 80 of the external plate C. By inserting the engaging projection 83 into the exterior plate engaging hole 65, the exterior plate C can be detachably attached to the front side of the plate frame B. FIG.

On the other hand, the plate body 80 of the exterior plate C is formed of a rectangular main part 81 covering the entire surface of the plate frame B by a thermoplastic synthetic resin such as ABS resin, and the main part ( It consists of a substantially box shape which integrally formed the side wall 82 so that it might not protrude to the back side from all the peripheral edges of 81. As shown in FIG. The locking projections 83 protrude from four corners on the rear side of the main portion 81. In addition, almost the center of the opening window (81a) which the grip 40 is exposed in the one switch (A ₁₎ mounted on the frame plate (B) is formed of a main part (81). Here, the width dimension between the opposing side wall 82 of the plate main body 80 is larger than each width dimension of the plate frame main body 51. That is, when the exterior plate C is mounted on the front side of the plate frame B attached to the mounting surface, the plate frame main body 51 enters the inside of the plate main body 80 of the exterior plate C, and the plate The leading edge of the side wall 82 of the main body 80 is almost in contact with the installation surface. As a result, the contact surface of the plate frame B and the exterior plate C does not go forward than the installation surface, and the contact line between them is almost invisible from the side surface, making it possible to look good.

Further, each side wall 82 of the plate body 80 is formed with an inclined surface 82a inclined toward the main portion 81 from the end edge in contact with the installation surface, and is provided on the side of the plate frame body 51, respectively. The regulating rib 84 which contacts in the direction along a surface and regulates the movement of the exterior plate C is mounted side by side. That is, when attaching the exterior plate C to the front side of the plate frame B, the regulating rib 84 contacts the side surface of the plate frame main body 51, and the exterior plate C with respect to the plate frame main body 51 is carried out. ) Can prevent shaking.

A pair of slit portions 86 is formed on one side wall 82 along the longitudinal direction of the plate body 80, and a jig (such as the front end of the driver) is inserted into the slit portion 86 to form a plate body. By applying the force to the front side to the 80, the engagement projection 83 of the plate main body 80 and the exterior plate engaging hole 65 of the plate frame main body 51 are released to release the external plate ( C) is to be removed from the plate frame (B). Here, at the position corresponding to the slit portion 86 of the side frame member 5Bb of the plate frame main body 51, a release portion 66 recessed inward from the tapered surface 53c is formed, and the slit portion It can be inserted to the inside by releasing the jig inserted into (86), and it is comprised so that a force may be applied easily when removing the exterior plate C. As shown in FIG. In addition, at the rear end of the release portion 66, the rib 67 of the portion thinner than the cut portion 53d extends to the extent that it does not protrude from the slit portion 86 of the exterior plate C. . That is, there is a risk that the mounting surface may be damaged by applying a force to the jig inserted into the slit portion 86 as a point, but it is inserted into the slit portion 86 by mounting the rib 67. The jig which contacts the rib 67 contacts the rib 67, and when the external plate C is removed from the plate frame B, it is possible to prevent the mounting surface from being damaged by the jig.

Further, on the back side of the plate main body 80, the protrusion members 88a to 88c fitted to the three slits 58a to 58c respectively formed on the plate frame main body 51 when mounted to the plate frame B are mounted side by side. It is. Here, the dimensions of each of the protruding members 88a to 88c are inserted into the respective slits 58a to 58c of the plate frame body 51, and the inner circumferential surfaces of the slits 58a to 58c and the respective protruding members 88a to It is set to the dimension which does not produce only a small gap between 88c). That is, in the state where the exterior plate C is mounted on the plate frame B on which the switch A ₁ is mounted, the three protruding members 88a to 88c are formed by the respective slits 58a to 58c of the plate frame body 51. Is inserted into the inner surface of the slit 58a to 58c and there is no small gap between the protrusions 88a to 88c. Therefore, the movement (bending) of the movable support part 55 of the plate frame body 51 is restricted. do. As a result, even when a shock is applied to the switch (A _1), is the movement of the movable supporting part 55 regulations as described above, because the switch (A _1), the swivel hook 13 and the movable support 55 and the fixed support of the The engagement of the locking grooves 5a and 4a of 54 is not easy to come off.

By the way, each of the locking grooves 54a and 55a of the fixed support portion 54 and the movable support portion 55 are mounted at six equal pitches, so that the switch A ₁ to the opening portion 52 of the plate frame body 51 is mounted. can be selected randomly from among several of the mounted position, by the mounting position of the switch (a ₁₎ of the plate frame (B) is increased, to be equipped with a facade plate (C) having an opening window (81a) corresponding to the respective mounting position There is also unreasonableness such as necessity.

Thus, as shown in Figs. 7A to 7C, in order to limit the mounting position so that all three switches A ₁ of one module size can be mounted with respect to the opening 52 of the plate frame B, The diaphragm rib 70 protrudes in the vicinity of the engaging grooves 54a and 55a of the fixed support portion 54 and the movable support portion 55. These diaphragm ribs 70 each have a pair of plate frames at positions outside the pairs of the engaging grooves 54a and 55a in which a total of three pairs are formed on the inner surfaces of the fixed support portion 54 and the movable support portion 55, respectively. It protrudes integrally with the main body 51. In other words, it may be equipped with a switch (A ₁₎ in a non-mounted position to replace all the three, the partition ribs (70) projecting between the locking groove (54a, 55a) monograph of the switches (A ₁₎ Since it interferes with the main body 1, it cannot be mounted.

Moreover, when the switch A ₁ is attached to the mounting position, the release recesses 15 to which the ribs 70 contact each partition are formed in the four corners of the side of the main body 1 (cover 1b). As a result, shaking of the switch A _{1 in} the state attached to the plate frame B can be suppressed by making the partition part 70 contact the release recess 15. As a result, even when unnecessary force is applied to the main body _{1 of the} switch A ₁ , it is possible to prevent the occurrence of discomfort such as breaking the catch ring 13.

The switch A ₁ can also be attached to the metal mounting frame D as shown in Figs. 8A to 8C. The mounting frame (D) is formed in a rectangular frame shape having three opening windows (90) in the center, and inserts box screws for mounting to a buried box in both side members (91) facing in the longitudinal direction. A long hole 92, a screw insertion hole 93 into which a screw for mounting directly on an installation surface such as a wall surface is inserted, and an insertion member secured by hanging an insertion member used for mounting to a wall panel or the like that forms the installation surface. A locking hole 94 and a screw hole 95 for screwing a metal outer plate or the like are attached.

On the other hand, opening the window mounting frame formed at the bottom between the side frame members (96a, 96b), the retaining ring in both sides of the cover (1b) of the switch (A ₁₎ (13) opposite along the longitudinal direction into the 90 Engaging rings 97 and 98 for engaging with the hole 17 are formed, respectively. In one of the side frame members 96b, the locking ring 98 is supported on both sides by a support member 99 having a fine width. That is, when attaching the switch A ₁ to the mounting frame D, the catch ring 97 of the side frame member 96a is first engaged with the edge mounting hole 17 of the switch A ₁ , and the like. By pressing the support member 99 of the other side frame member 96b toward the opening window 90 side by using a tool, the hook 98 is caught in the edge mounting hole 17 of the switch A ₁ . In engagement, the switch A ₁ can be attached to the mounting frame D. FIG.

By the way, there is a buried box (so-called C-type box) of a round frame having an almost circular opening in a buried box buried in an installation surface such as a wall surface, but at least two in relation to the size of the main body _{1 of the} switch A ₁ . It may not be possible to mount all the switches A ₁ . Thus, the corner portions 1c of the main body 1 (the body 1a and the cover 1b) of the switch A ₁ are cut in the upward and downward directions. As a result, even when the two switches A ₁ are all embedded, for example, as shown in FIG. 9, the corners 1c of the main body _{1 of the} respective switches A ₁ are cut and rounded. It is not to interfere with the embedding of the frame box, a switch (a ₁₎ to the embedded box in a round frame and is able to both the plurality of buried mounting.

By the way, as shown in Figs. 10A to 10C, all three switches A ₁ in the present embodiment can be mounted on the three plate frames B, and the operation handle 40 in the case described above. The dimension in the short width direction of the operation surface is about one third of the dimension in the longitudinal direction of the opening portion 52 of the plate frame B. On the other hand, in the case where only two switches A ₁ are to be mounted on one plate frame B, the longitudinal dimension of the opening 52 of the plate frame B as shown in Figs. 11A to 11C is shown. The operation handle 40 'having an operation surface of about one-half dimension (two module dimensions) may be attached to the intermediate handle 30. That is, since the opening 52 of the plate frame B is blocked by the operation handle 40 of the switch A ₁ mounted at both ends of the opening 52, the opening window 8la of the exterior plate C is closed. There is no need to change the dimensions of the to match the number of switches A ₁ . In addition, when only _one switch A ₁ is to be attached to one plate frame B, an operation surface having the same dimensions (three module dimensions) as the opening portion 52 shown in Figs. 12A to 12C. The operation handle 40 'having the intermediate handle 30 may be mounted. It goes without saying that the switch A ₁ can be mounted on the back side of the plate frame B in a state in which either of the operation handles 40 'and 40 "is attached to the intermediate handle 30. FIG. In this way, a switch device can be configured by mounting one to three switches A ₁ to the common plate frame B, and the plate frame B can be used without depending on the number of switches A ₁ to be mounted. And the appearance plate (C) can be used in common, so that the cost can be reduced.

Moreover, also when attaching to the metal mounting frame D instead of the plate frame B as shown to FIG. 13A-13C, one, two, three each module like the plate frame B What is necessary is just to equip the intermediate | middle handle 30 with the operation handle 40 of a dimension.
