[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof button rubber for a toggle switch used in outdoor equipment such as a remote controller used for remote control of a working machine such as a crane.

[0002]

2. Description of the Related Art As one of outdoor equipment, a remote controller for remotely controlling a working machine such as a crane as shown in FIG. 3 has been considered.

The remote controller 1 can be hung on the waist of a person with a hanger 2 when not in use, and is provided with a plurality of toggle switches 3, a pistol-type operation lever 4, and the like. An operation panel 5 and a rod-shaped grip 6 connected to the operation panel 5 and having a substantially elliptical cross section are provided. When the grip 6 is used, the toggle switch 3 and the operation are held. By selectively operating the lever 4 or the like, a work machine such as a crane performs a desired operation.

Here, as shown in FIG. 2, the toggle switch unit 3 includes a toggle switch 10 installed on a substrate 8 disposed in the operation panel unit 5 and a rainwater or the like in the operation panel unit 5. In order to prevent the intrusion, two button rubbers 20 and 30 for waterproof made of a flexible material such as rubber are provided so as to cover the toggle switch 10.

The toggle switch 10 is provided with an operating rod 11 having a knob 12 having a knob 12 mounted thereon, which is projected outward from an opening 9 formed in the outer cover 7 and is swung to open and close a contact. Have.

On the other hand, of the button rubbers 20, 30, the button rubber 20 disposed on the inner side (lower side) has an outer periphery disposed below the outer cover 7 so as to close the opening 9 of the outer cover 7. Film-like portion 22 sandwiched between the formed spacer 13 and the spacer 14 disposed further below the same, and a knob attached to the upper portion of the operation rod 11 and connected to the film-like portion 22 12 is applied via an adhesive 16,
It comprises an inverted bottomed tubular cylindrical knob insertion portion 25 that can be swung back and forth or left and right together with the knob-equipped operation rod 11.

The button rubber 30 arranged on the outside is also provided.
A covering film-like portion 32 whose outer periphery is sandwiched between the outer cover 7 and a spacer 13 disposed below the outer cover 7 so as to close the opening 9;
An inverted bottom which is connected to the film-like portion 32, is attached to the knob insertion portion 25 of the button rubber 20 via the adhesive 17, and is swung together with the operation rod 11 with the knob and the button rubber 20. The knob insertion portion 35 has a rectangular cylindrical shape.

[0008]

However, in the toggle switch section 3 described above, the inner surface of the knob insertion portion 25 of the button rubber 20 and the side peripheral surface of the knob 12 of the toggle switch 10 are joined by an adhesive 16. The knob insertion part 25
Is swung so as to be twisted along with the knob-equipped operation rod 11, so that the knob may be peeled off from the knob 12, and the operation of the toggle switch 10 becomes difficult.

Further, since an adhesive is used for joining the knob insertion portion 25 and the knob 12, assembly work is troublesome, and there is a problem that the knob cannot be disassembled even during maintenance and inspection.

In view of such a point, the present invention can securely connect the knob insertion portion and the knob of the notch switch without using an adhesive, and the knob insertion portion is not easily detached from the knob of the toggle switch. It is an object of the present invention to provide a waterproof button rubber for a toggle switch which can be easily assembled and can be easily separated at the time of maintenance and inspection.

[0011]

In order to achieve the above object, a waterproof button rubber of a toggle switch according to the present invention is provided through an opening formed in an outer cover of equipment used outdoors such as a remote controller. It is made of a flexible material such as rubber which is covered so as to cover a toggle switch having an operation rod with a knob which is projected outward and is swung to open and close the contact, so as to close the opening of the outer cover. A cover-like portion attached to the cover-like portion, and an inverted bottomed cylindrical shape which is connected to the cover-like portion, is attached to the upper portion of the knob-equipped operation rod, and is swung together with the knob-equipped operation rod. A knob insertion portion is provided, and a retaining projection which is locked to an outer edge of the lower end of the knob projects from an inner edge of a lower end of the knob insertion portion.

[0012]

In the waterproof button rubber of the toggle switch according to the present invention constructed as described above, the retaining protrusion protruding from the inner edge of the lower end of the knob insertion portion is provided on the outer edge of the lower end of the knob of the toggle switch. Since the operation lever with the knob of the toggle switch is rocked back and forth or left and right, the button rubber and the knob are not easily separated from each other.

[0013] Therefore, the knob insertion portion and the knob of the notch switch can be securely connected without the need for an adhesive, and further, since there is no need to use an adhesive for the connection, the assembling work is simplified. They can be easily separated at the time of maintenance and inspection.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a toggle switch unit using a waterproof button rubber according to the present invention. In the figures, the same reference numerals are used for parts corresponding to the respective parts of the conventional toggle switch unit shown in FIGS. 2 and 3 described above. And the description thereof will be omitted, and the differences will be mainly described below.

As shown in FIG. 2, a waterproof button rubber 20 of the toggle switch according to the present embodiment has a film-like portion 22 disposed so as to close the opening 9 of the outer cover 7, and A knob insertion part 25 which is attached to the knob 12 attached to the upper part of the operation rod 11 and is attached to the upper part of the operation rod 11 and which can be swung together with the operation rod 11 with the knob. doing.

Further, in addition to the above configuration, a retaining projection 25a which is locked to the outer edge of the lower end of the knob 12 is protruded inward all around the inner edge of the lower end of the knob insertion portion 25.

By doing so, the retaining projection 25 protruding from the inner edge of the lower end of the knob insertion portion 25 is locked to the outer edge of the lower end of the knob 12 of the toggle switch 10.
Even if the knob-equipped operation rod 11 of the toggle switch 10 is swung back and forth or left and right, the button rubber 20 and the knob 12 are not easily separated.

As a result, the knob insertion portion 25 and the knob 12 of the notch switch 10 can be securely connected without the need for an adhesive, and the bonding can be performed without using an adhesive. Can be easily performed, and they can be easily separated at the time of maintenance and inspection.

[0019]

As is apparent from the above description, according to the waterproof button rubber of the toggle switch according to the present invention, the knob insertion portion and the knob of the notch switch can be securely connected without requiring an adhesive. In addition, the knob insertion portion can be prevented from easily coming off the knob of the toggle switch, and the assembling work can be easily performed, and they can be easily separated during maintenance and inspection. Can be
