Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to a switch mounting device.

(Prior Art) It is sometimes required to attach a switch to the end face of a cylindrical body. For example, it is possible to make a handrail for stairs hollow, store a lighting lamp inside it, project light from the lamp through a window installed on a part of the side of the handrail, and use that light to illuminate the stairs. be. In such cases, the above-mentioned switch for blinking the lamp is attached to the end face of the handrail.

Conventionally, in order to install this switch, the switch was held between an end cap that was fixed to the handrail so as to close the end face of the handrail, and a metal fitting that was fixed to the side of the handrail with screws. I was trying to fix it.

However, according to this method, the metal fittings must be inserted into the handrail in advance and fixed with screws. Therefore, work such as inserting metal fittings and fixing them with screws is required, and therefore, the work of installing this type of switch is extremely troublesome.

(Problems to be solved by the invention) The purpose of this invention is to enable a switch to be easily attached to the end face of a cylindrical body such as a handrail.

(Means for solving the problem) This invention consists of elastically holding the switch from both sides with a U-shaped holding metal fitting, and forming a bent edge by bending the tip of the holding metal fitting outward. Insert the presser metal fitting into the end surface of the cylindrical body while holding the switch so that the outer periphery is in contact with the end surface of the cylindrical body, and insert the end cap to close the end cap onto the end surface of the cylindrical body. It is characterized in that the outer periphery of the bent edge is sandwiched between and fixed to the end surface of the cylindrical body.

(Example) An example of this invention will be described with reference to the drawings. 1 is a cylindrical body to be attached, such as a handrail; 2 is an open end face thereof; 3 is an end cap fixed with a screw 4 so as to close this end face;
5 is a switch to be attached. The end cap 3 is provided with a window 3A through which an operating section of the switch 5, such as a push button section 5A, passes through.

According to this idea, a presser metal fitting 6 is prepared. This presser metal fitting 6 is configured in a U-shape by a base wall 7 and a pair of side walls 8 continuous on both sides thereof, and furthermore, the tip of each side wall 8 is bent outward to form a bent edge 9. . Both side walls 8 are inclined so that the tip side thereof is wider than the width of the switch 5.

In the above configuration, when attaching the switch 5 to the handrail 1, the switch 5 is first inserted between the both side walls 8 of the metal fitting 6. After its insertion, if the side walls 8 are pushed inwardly, the switch 5 will be elastically held by the side walls 8 around its periphery.

In this case, the tip of the side wall 8 and therefore the base end 9A of the bent edge 9 are brought into contact with the side surface of the switch 5. Further, by extending the upper and lower parts of the bent edge 9 inward to form an extension part 10, and making sure that the inner edges thereof come into contact with the upper and lower circumferential surfaces of the switch 5, the switch 5 can be held securely. It's convenient.

The presser metal fitting 6 holding the switch 5 as described above
is inserted into the end face 2 of the handrail 1. Then, the outer periphery of the bent edge 9 is brought into contact with the end surface 2. Next, in this state, the end cap 3 is fitted onto the end face 2.
At this time, the push button portion 5A comes to be pulled out from the window 3A.

By fitting the end cap 3 described above, the outer periphery of the bent edge 9 comes to be sandwiched between the periphery of the end surface 2 and the end cap 3. After that, attach the end cap 3 to the handrail 1 using the screw 4.
Fixed to. With the above steps, the installation of the switch 5 is completed.

(Effects of the invention) As detailed above, according to this invention, the switch can be operated by simply inserting the presser metal fitting holding the switch into the end face of the cylindrical body and fixing the end cap to the cylindrical body. It can be attached to the end face of a cylindrical body, and in that case there is no need to insert and fix the metal fittings into the cylindrical body in advance, unlike conventional methods, so the installation work is extremely simple. play.
