Abstract

PROBLEM TO BE SOLVED: To insertion-fit a grommet into a fitting hole easily and quickly by providing a wedge-like forked part composed of a plane part in parallel with the axis and a taper face part having inclination relative to the plane part, and pinching the grommet shaft part with the forked part to forcedly insert the grommet into the fitting hole. SOLUTION: A forked part 3 provided on the extreme end of a holding handle 1 is formed into a wedge-like form composed of a plane part 4 in parallel with the axis of the holding handle 1, and a taper face part 5 having inclination relative to the plane part 4. The shaft part of a grommet is inserted into the forked part 3 to be pinched by the extreme end of a tool, and while the holding handle 1 has inclination relative to the upper face of a work, the lower flange of the grommet is inserted into a fitting hole and the grommet is continued to be pushed, the flange of the grommet is pinchedly fitted to the work. By turning the holding handle 1 by 90 degrees from the upper face of the work to let it stand up, the taper face part 5 is brought in contact with the inner diameter of the fitting hole to act as leverage, and the shaft part and the upper flange of the grommet is pressed with the plane part 4 to be compressively deformed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grommet insertion tool for easily and quickly inserting a grommet into a mounting hole.

[0002]

2. Description of the Related Art As shown in FIG. 4, flanges 8b having a diameter d2 larger than the diameter d1 of the shaft 8a are provided at both ends of the shaft 8a.
8c is formed with a mounting hole 7 formed in the work 6 by a spool-shaped grommet 8 (for example, rubber for vibration isolation).
In the past, when the work 6 was sandwiched and fixed by the flanges 8b and 8c, a sliding liquid was applied to the grommet 8 and pushed into the mounting hole 7 with a fingertip of an operator.

[0003]

In the above-mentioned conventional insertion operation, when inserting, the diameter d is larger than the diameter of the mounting hole 7.
One of the flanges 8b and 8c must be inserted into the mounting hole 7 and penetrated, so that the insertion is difficult and much time is required.

[0004] It is an object of the present invention to provide a grommet insertion tool capable of easily and quickly inserting and mounting a grommet in a mounting hole.

[0005]

In order to achieve the above object, the present invention provides a spool-type grommet in which flanges having a diameter larger than the diameter of the shaft are formed at both ends of the shaft. A tool to be inserted into the mounting hole, wherein a wedge-shaped bifurcated portion including a flat portion parallel to the axis of the grip handle and a tapered surface portion having an inclination angle with respect to the flat portion is provided at the tip of the grip handle, It is characterized in that the fork is inserted into the mounting hole with the shaft of the grommet being sandwiched between the forked portions.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a tool according to the present invention, and FIG. 2 is a plan view. 1 and 2, reference numeral 1 denotes a grip handle. The grip handle 1 is provided with a knurl 2 for slip prevention.

A forked portion 3 is provided at the tip of the grip handle 1. The bifurcated portion 3 has a wedge-like configuration including a flat portion 4 parallel to the axis of the grip handle 1 and a tapered surface portion 5 having an inclined angle with respect to the flat portion 4.

The procedure for inserting the grommet 8 using the tool of the present invention will be described with reference to FIG. As shown in FIG. 4, the grommet 8 has a spool shape in which flanges 8b and 8c having a diameter d2 larger than the diameter d1 of the shaft portion 8a are formed at both ends of the shaft portion 8a, and is made of an elastic material such as rubber or synthetic resin. It is.

The shaft 8a of the grommet 8 is inserted into the forked portion 3 and clamped at the tip of a tool. Then, FIG.
As shown by, the gripping handle 1 is inclined with respect to the upper surface of the work 6 and the flange 8c below the grommet 8 is inserted into the mounting hole 7. The inclination angle is suitably 45 °.

In the state shown in FIG.
Press and hold. Thus, as shown in FIG. 3B, the concave groove between the downward flanges 8b and 8c of the grommet 8 fits into the edge of the mounting hole 7, and the shaft portion 8a comes into contact with the mounting hole 7 and the flange 8b , 8c are clamped to the work 6.

From the state shown in FIG. 3 (B), the handle 1 is turned upright by 90 ° with respect to the upper surface of the work 6. Thus, as shown in FIG. 3C, the wedge-shaped forked portion 3 has the tapered surface portion 5 abutting against the inner diameter of the mounting hole 7 to perform a lever action, and the flat portion 4 presses the shaft portion 8a and the upper flange 8b. The lower flange 8c is pushed out below the mounting hole 7 while being compressed and deformed. The extruded lower flange 8c is extended and engaged with the lower surface of the work 6 by its own elastic force.

From the state shown in FIG. 3C, FIG.
By raising the grip handle 1 directly above as shown by
The shaft portion 8a and the upper flange 8b, which have been compressed and deformed by being pressed by the flat portion 4 of the forked portion 3, are brought into contact with the mounting hole 7 by their own elastic force.
b extends and engages with the upper surface of the work 6 to complete the insertion and mounting of the grommet 8.

As described above, the grommet 8 can be easily and quickly inserted and mounted by pushing the grommet 8 into the mounting hole 7 at an inclined angle by the tool and erecting the tool.

[0014]

As described above, according to the tool of the present invention, the grommet can be easily and quickly inserted into the mounting hole without any skill, so that it is possible to insert the grommet without damaging the fingertip. This has the advantage that the mounting time can be reduced.
