Description

[Detailed Description of the Invention] The present invention relates to a handle for a hand tool, and more specifically, to a grip body having a grip between the tips of a pair of semi-cylindrical forked parts, and a base of the forked parts. This invention relates to handles for manual tools such as shovels and scoops, which are comprised of a handle body of a predetermined length that is attached to the handle.

Conventionally, in the case of handles for hand tools of this type, for example, handles for shovels, the means for connecting the grip body and the handle body is such that the bases of the forked portions of the grip body are in contact with each other, and each base is The base end of the handle body made of a metal pipe is welded to the tip of the handle to connect the grip body and the handle body.

However, with such a welding connection means, not only is the welding work very troublesome and complicated, but also there is a problem that the surface finish is poor.

In addition, as another coupling means, at the base of the forked part,
In some cases, the grip body and the handle body are connected by fitting the heads of two headed handle bodies and passing a pin through the fitting portion between the base portion and the head. In this case, in addition to the fitting operation of the handle body to the base portion, a connecting operation by passing the pin through must be performed, and this connecting operation using the pin is troublesome and time-consuming.

This idea was devised in view of the above circumstances.
The purpose of this is to fit the cap to the outer surface of the base of the forked part of the grip body, and press-fit the handle body into the fitting part formed at the base, which can be welded or The object is to quickly and easily connect the grip body and the handle body without using a pin.

Therefore, the present invention forms a fitting part for the handle body by cutting out the opposing inner wall of the root part of the forked part, and also bends the tip of the base part inward so that the outer diameter of the handle body A semicircular pressing piece with a smaller diameter is formed, and a cylindrical cap is tightly fitted to the outer periphery of the base portion to absorb elastic deformation of the pressing piece, and the handle is A tapered insertion part having a smaller diameter than the tip of the pressing piece is formed at the base end of the main body, and the pressing piece is elastically deformed by fitting into the fitting part of the handle main body, The handle body is fixed to the base portion.

Embodiments of the present invention will be described below based on the drawings.

The one shown in the figure is a shovel, and 1 is 1
A grip body 2 includes a grip portion 20 between the distal ends of a pair of forked portions 21, 21 exhibiting a pair of semi-cylindrical shapes, and a grip body 2 having a predetermined length attached to the root portions 22, 22 of the forked portions 21, 21. A shovel handle consisting of a pipe-shaped handle body 3, and a blade 4 at the tip 31 of the handle body 3.
is firmly attached.

Thus, the fitting portion 2 is made by cutting out the opposing inner walls 22a, 22a of the root portions 22, 22 in the fork-like portions 21, 21 to have approximately the same diameter as the outer diameter of the handle body 3.
3, and the tips of the root portions 22, 22 are bent inward to form semicircular pressing pieces 24, 24 having a smaller diameter than the outer diameter of the handle body 3, and A cylindrical cap 5 is tightly fitted to the outer periphery of the pressing pieces 24, 22.
The handle body 3 is formed so as to absorb the elastic deformation of the
A tapered insertion part 32 having a smaller diameter than the tips of the pressing pieces 24, 24 is formed at the base end of the pressing pieces 24, 24, and by fitting into the fitting part 23 of the handle body 3, the pressing pieces 24, 24 is elastically deformed to fix the handle body 3 to the base portions 22, 22.

The cap 5 has a tapered part 51 formed by bending one end thereof so that it has approximately the same diameter as the outer diameter of the handle body 3, and the tapered part 51 allows the base part 2 to be bent.
The ends of the pressing pieces 24, 24 can be hidden.

Moreover, cylindrical receiving parts 25, 25 facing each other are formed at the distal ends of the forked parts 21, 21, and a wooden grip part 20 is fitted into each of these receiving parts 25, 25. 20 and the receiving parts 25, 25 with a nail 2
It is fixed by 6.

The present invention is constructed as described above, and when connecting the grip body 2 and the handle body 3, first, the base portions 2 of the forked portions 21, 21 of the grip body 2 are
The cap 5 is tightly fitted around the outer periphery of the base portions 22, 22 so as to absorb the elastic deformation of the pressing pieces 24, 24 of the base portions 22, 22.

Next, the base portion of the handle body 3 is press-fitted into the fitting portion 23 of the base portions 22, 22. During this press-fitting, the handle body 3 is inserted into the insertion portion 3 provided at its base.
2 and is press-fitted into the fitting portion 23, and the handle body 3 elastically deforms the pressing pieces 24, 24 at the base portions 22, 22 so that they come into close contact with the inner wall of the cap 5, and the pressing Piece 24,
Due to the elastic restoring force of 24, the handle body 3 and the grip body 2
and cap 5 can be combined.

As a result, at the same time as the handle body 3 is press-fitted into the fitting portion 23, the restoring force due to the elastic deformation of the pressing pieces 24, 24 is utilized to increase the strength of the connection between the three, thereby ensuring secure fixation. It is possible.

Incidentally, an annular recess 33 is formed at the base of the handle body 3 as shown in FIG. 6, and when the handle main body 3 is press-fitted into the fitting part 23, the tips of the pressing pieces 24, 24 are inserted into the annular recess. 33 may be fitted. With this configuration, by fitting the tips of the pressing pieces 24, 24 into the annular recess 33, it is possible to further strengthen the prevention of the handle body 3 from coming off from the fitting part 23.

Further, the cap 5, the base portion 22 and the handle body 3
After the grip body 2 is connected to the handle body 3, if a recess is formed in these three parts by driving with a punch or the like, rotation of the grip body 2 with respect to the handle body 3 can be more firmly prevented.

Further, although the above embodiment is applied to a shovel, it goes without saying that it can also be applied to the handle of a shovel and agricultural hawk, although not shown.

As described above, in the present invention, the opposing inner wall of the root portion of the forked portion is cut out to form the fitting portion of the handle body, and the tip of the root portion is bent inward to form the handle body. A semicircular pressing piece is formed with a diameter smaller than the outer diameter of the pressing piece, and a cylindrical cap is tightly fitted around the outer periphery of the base portion to absorb elastic deformation of the pressing piece. A tapered insertion portion having a smaller diameter than the tip of the pressing piece is formed at the base end of the handle body, and the pressing piece is elastically deformed by fitting into the fitting portion of the handle body. Since the handle body is fixed to the base portion, when the grip body and the handle body are connected, there is no need to weld or use pins as in the past. The grip body and the handle body can be quickly and easily connected by a simple coupling operation of fitting the cap to the outer surface of the base of the forked part and press-fitting the handle body into the fitting of the base. Moreover, when the handle body is press-fitted, the pressing piece in the forked portion is elastically deformed toward the inner surface of the cap, and this elastic deformation is used to move the grip body between the cap and the handle body. can be reliably and firmly bonded to the

Moreover, the appearance can also be improved.
