Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch in which an operating body larger than the boss portion of the switch is attached to a reversing element, and a load is turned on and off by the reversing operation.

Conventionally, this type of switch has a hole c formed in the surface b of a reversing element a, as shown in FIG. The operating body d, which is larger than the boss portion, is attached to the inverter a. Therefore, when installing, the claw piece e will be bent, and the claw piece e, which serves as the locking portion, may be damaged.

This invention was made in view of the above-mentioned circumstances, and its purpose is to enable the operating body to be firmly fixed to the inverter, to allow it to be detachably attached, and to prevent damage to the locking part. To provide a preventive switch.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 5. Reference numeral 1 designates a mounting frame, which has mounting holes 3 at both ends for fixing screws 2 to the embedded box X or construction surface W, and holes 4 at diagonally corresponding positions.
By forming the bending piece 5, an auxiliary fulcrum 5a of the operating body 6 is formed, and the side surface 7a of the switch 7 is supported. 8 is a screw hole into which the assembly screw 9 of the switch 7 is screwed. A hole 7b is formed in the boss portion 7a of the switch 7, and the inverter 10 is loosely fitted into the hole 7b. This inverter 10
The surface 10 is a rib 12 with grooves 11 formed on all sides.
The fixing spring 4 is provided in a concave chamber 13 formed in the concave chamber 13, and the fixing spring 4 is housed in the concave chamber 13. In other words, the top end 14a of the fixing spring 14 is lower than the top end 13a of the concave chamber 13. 13b is a notch provided in the wall 13c of the recessed chamber 13. The fixed spring 14 has a claw piece 1 that locks in the groove 11.
The bottom surface 17 has a chrysanthemum hole 16 with a hole 16 provided therein, and both side pieces 18 are formed in a U-shape. It is raised to form a locking piece 20. 21
is a hole, and by storing the shavings generated when the pawl piece 15 is press-fitted into the groove 11, it prevents the fixing spring 14 from shifting and fitting into the recessed chamber 13 due to the action of the shavings. There is. Note that the hole 21 may be replaced with a protrusion. 22 is a light emitting element for on display; 2
3 is a light emitting element for off display. A lower frame 24 has a frame shape with a hole 25 through which the switch 7 passes, and forms an abutting portion 26 on which the mounting frame 1 is placed. Assuming that the horizontal dimension of the mounting frame 1 is a and the vertical dimension is b, the hole 25 has a horizontal dimension c larger than a and a vertical dimension d smaller than b. A protrusion 26a is formed on the abutting portion 26 so as to fit into the hole 4 to maintain the mounting frame 1 and the lower frame 24 in their normal positions. 27 is a rib formed around the hole 25, and 28 is a long hole for positioning. Then, the contact portion 2 corresponding to the mounting hole 3
6 is a screw 2 when the lower frame 24 is brought into contact with the construction surface W.
The lower frame 24 is formed by plastic molding of a thermoplastic resin such as PBT resin, Noryl resin, or ABS resin containing glass fiber to provide elasticity and hardness. It is set up.
30 is a plate main body, which has a bottom surface 30a having approximately the same size as the lower frame 24, a rib 31 that fits into the rib 27, and a protrusion 32 that fits into the long hole 28. . And the lower frame 24
A groove 33 is formed around the entire circumference of the abutting portion P between the plate body 30 and the plate body 30, so that the whole body appears thin. Incidentally, this groove 33 may be formed in the lower frame 24 as shown in FIG. 3b. Reference numeral 34 denotes a window hole, which is formed larger than the boss portion 7a of the switch 7, and a support portion 35 and a flexible locking claw 36 are formed inside the window hole 34a. 37 is the middle frame, which is made of die-cast material to provide strength. Then, as shown in FIG. 3b, a stepped portion 38 into which the locking pawl 36 is fitted is formed, and a contact portion 39 is formed.
is formed and placed on the support portion 35, and the stepped portion 3 is placed on the supporting portion 35.
A locking pawl 36 is fitted into the plate 8 to integrate it with the plate body 30. Furthermore, the abutting portion 39 hides the gap when the top plate 6 is attached. In this state, a part of the middle frame 37 protrudes beyond the plate main body 30, emphasizing the external design. A fixing screw 40 is screwed into the screw hole 1a of the mounting frame 1 to fix the plate main body 30 to the mounting frame 1. Reference numeral 6 denotes an operating body, and as shown in FIG.
a, and a rib 42 that loosely fits into the notch 13b is formed at a position corresponding to the central axis that performs the reversing operation, and is engaged with the locking piece 20 on the side where force is applied during the reversing operation. A protrusion 43 is formed, and a window hole 34 is formed.
The switch 7 is loosely fitted to the switch 7. 4
Reference numeral 4 denotes a transparent body attached to the hole 45 so that the blinking state of the light emitting elements 22 and 23 can be visually confirmed from the outside. The device is arranged so that the side on which the operating body 6 falls is illuminated.

When the switch 7 is to be attached to the construction surface W, the switch 7 is first fixed, and the mounting frame 1 with wiring attached thereto is fixed to the embedded box X or the construction surface W with the screws 2. Next, a decorative material Y such as a cloth is attached to the construction surface W, and the decorative material Y is cut along the mounting frame 1 to expose the switch 7. After loosening the screws 2, the lower frame 24 is attached to the lower surface of the mounting frame 1. At this time, first, the notch 29 is loosely fitted to the screw 2, and the mounting frame 1 is positioned on the lower frame 24 through the hole 25. Therefore, the lower frame 24 can be mounted on the lower surface of the mounting frame 1 without removing the mounting frame 1. Then, the mounting frame 1 is placed on the contact portion 26, the hole 4 is fitted into the protrusion 26a, and the screw 2 is tightened. Therefore, even if the decorative material Y is thick, by tightening the screws 2, the entire decorative material Y in contact with the lower frame 24 is pushed down, as shown in FIG. Next, after fixing the plate body 30 to the mounting frame 1 with the fixing screws 40,
While loosely fitting the operating body 6 into the window hole 34, the rib 1
2 as a guide, push the cylindrical rib 41 into the concave chamber 13, lock the protrusion 43 on the locking piece 20, and then switch 7.
is attached. Therefore, there is no need to worry about the boss portion 10 being stained by the decorative material Y such as cloth. In this case, by fixing the middle frame 37 to the mounting frame 1 and forming the contact portion 39, the operating body 6
Even when the operating body 6 is larger than the boss portion 7a, the reversal angle can be maintained at the normal position.

As described above, the present invention provides a rib 12 that loosely fits into the hole 7b of the boss portion 7a and has grooves 11 formed on all sides.
is provided in the recessed chamber 13 and has a notch 13b formed in the wall 13c of the recessed chamber 13 corresponding to the central axis for reversing operation, and a claw piece 1 that is engaged with this groove 11.
A bottom surface 17 with a chrysanthemum hole 16 provided with a hole 16 and both side pieces 18 are formed in a U-shape, and the tips of the side pieces 18 are opened outward to form a guide piece 19, which is cut and raised outward from the middle. A fixed spring 14 formed with a locking piece 20 and housed in the concave chamber 13, and a cylindrical rib 41 that loosely fits into the rib 12 and fits in the concave chamber 13 are formed on the back surface 6a and further loosely fits into the notch 13b. Since the operating body 6 is formed with matching ribs 42 and has a protrusion 43 that engages with the locking piece 20 on the side on which force is applied during the reversing operation, the operating body 6 can be firmly fixed to the inverter 10. At the same time, the spring property of the fixing spring 14 allows the switch to be attached and removed freely, and furthermore, by housing the fixing spring 14, which is the locking part, in the recessed chamber 13, the switch can prevent damage to the locking part. can get.
