BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chisel.

[0002]

2. Description of the Related Art Conventionally, a technique for manufacturing a chisel handle by double molding has been known. This is a molding technique in which a core made of a hard material such as an ABS resin is set in a mold, and a soft resin such as an elastomer is injected into the cavity to obtain a handle. The plastic handle thus formed has a clean appearance and can be easily wiped off even if it becomes dirty. Furthermore, since the entirety is covered with the soft resin, it is hard to slip no matter where it is gripped and it is easy to hold.

[0003] When a handle is manufactured by double molding, the core is generally supported by a mold and molded. Therefore, the core cannot be completely covered with a soft resin. In some cases, it was exposed on the outer surface.

[0004]

Conventionally, when the mold is removed after molding in this manner, the supporting portion is naturally exposed on the outer surface, and the exposed core has a special meaning. I didn't let it. At best, from the viewpoint of aesthetic treatment, the handle is only accentuated by the exposed core body in a different color from the soft resin of the jacket and the core body, and there was no idea of actively using the exposed core body.

The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to visually recognize an exposed portion of a core exposed on the outer surface of a handle from a plurality of chisels having different blades. By doing so, the desired blade chisel can be easily identified.

[0006]

In order to solve the above-mentioned problems, the present invention is directed to a first aspect of the present invention in which a hard core is coated with a resin to form a handle of a chisel, and the same pattern is formed. In the chisel equipped with a blade at the tip, an exposed portion where the core was exposed was formed in a part of the handle of the chisel, and a mark imitating the shape of the blade of the chisel was formed in the exposed portion. That is the gist. A second aspect of the present invention is that, in the first aspect of the present invention, the mark is formed in a concave shape on an exposed portion. The invention of claim 3 is a gist of the invention of claim 1 or 2, wherein the mark is formed near the base end of the handle.

[0007]

According to the first aspect of the present invention, a mark having a shape imitating the shape of the blade of each chisel is formed on the exposed portion exposed on the outer surface of the handle. Therefore, it is possible to select a desired chisel from a plurality of chisels without directly checking the blade by looking at the mark. Claim 2
In the device of the present invention, in addition to the function of the device of the first aspect, since the mark is engraved in the exposed portion in a concave shape, the engaging portion of the mold is engaged with the mark to hold the double mold. Part. Further, in the invention of claim 3, claim 1 or 2
In addition to the operation of the inventor, since the mark is formed near the base end of the handle, for example, the chisel is stored in a state where the tip of the handle with the blade body is hidden in the chisel case. Even if the base end of the handle with the mark is out of the case, a desired chisel can be selected.

Exposed portions of the ABS resin of the core are formed on the side surfaces near the base end of a to 4e. And each exposed part 6
a to 6e have blades 3a of the chisel 1a to 1e, respectively.
Marks 7a to 7e representing the shapes of 3e to 3e are engraved.
Each of the exposed portions 6a to 6e is a holding portion for holding the core body in the mold when the handles 4a to 4e are manufactured by double molding.

Next, the storage case 2 for storing the chisel 1a to 1e will be described with reference to FIG. The storage case 2 is formed of an ABS resin, and includes a case body 10 and a lid 11. The case body 10 is formed with compartments 9 for accommodating the chisel 1a to 1e, and the chisel 1a to 1e for accommodating the chisel 1a to 1e is assigned in advance. The depths of the receiving holes 9 are chisel 1a, respectively.
When each of the exposed portions 6a to 4e is accommodated,
Marks 7a to 7e formed on 6e have such a depth that they are completely exposed.

Guide pieces 13 extend from both sides of the opening of the case body 10 as shown in FIG. A guide hole 14 is provided in the guide piece 13 in the longitudinal direction at the center thereof. As shown in FIG. 7, the guide hole 14 has a pair of upper and lower locking projections 15 formed on the inner peripheral surface on the distal end side. The guide hole 14 has a bearing portion 14a at the distal end and a guide portion 14b at the proximal end with a pair of upper and lower locking projections 15 as boundaries.

As shown in FIG. 7, a contact plate 16 is formed on the lower surface of the case body 10 so as to extend therefrom. The abutment plate 16 has engraved marks 9a to 9e representing the chisels 1a to 1e to be housed in the housing holes 9 at the entrance portions of the housing holes 9 on the upper surface thereof. Each mark 9a to 9e formed on the contact plate 16
Is a mark 7a formed on the handle 4a-4e of the chisel 1a-1e
7e. Therefore, chisel 1
When ac to 1e are accommodated in each accommodating hole 9, markings 9a to 9e formed on the contact plate 16 and marks 7a to 7 of the handles 4a to 4e are provided.
e and the chisels 1 a to 1 corresponding to the predetermined accommodation holes 9.
1e is stored.

Next, the lid 11 will be described. As shown in FIGS. 7 and 8, the lid portion 11 includes a fitting portion 18 and arm portions 19 extending from both right and left sides of the fitting portion 18. The base portions of the chisels 1a to 1e are fitted to the fitting portions 18. On the front surface of the fitting portion 18, a window portion 20 for visually recognizing the marks 7a to 7e of the chisels 1a to 1e is formed with a large cutout.

As shown in FIGS. 9 to 11, a pair of arms 19 extending from the fitting portion 18 have a shaft 22 formed on the inner surface of the distal end. The shaft 22 is fitted in a guide hole 14 formed in the guide piece 13 and slides along the guide hole 14. At this time, when the lid 11 is in the state of FIG. 10, that is, when the shaft 22 is pulled out to the bearing 14a, the lid 11 is
As shown in FIG. As a result, as shown in FIG. 7, the storage case 2 is in an open state, and the chisels 1 a to 1 e can be pulled out from the storage holes 9.

Next, the operation of this embodiment will be described.
As shown in FIG. 6, the chisels 1 a to 1 e have most of the blades 3 a to 3 e and the handles 4 a to 4 e on the tip side accommodated in the accommodation hole 9 of the case body 10. In this state, if
When the operator wants to use the cutting knife, which is the chisel 1b, the user visually recognizes the mark 7b and slides the cover 11 to store the storage case 2.
Is opened, and the chisel 1b is taken out. Similarly, when it is desired to use another chisel 1a, 1c-1e such as a flat sword or a round sword, the marks 7a, 7c-7e are visually recognized and taken out. Then, when stored in the storage case 2 after use, the stamps 9a to 9e formed on the contact plate 16 and the handles 4a to 4e
Are stored in a predetermined storage hole 9 by collating with the marks 7a to 7e.

With the above configuration, the present embodiment has the following effects. 1) Conventionally, when manufacturing a molded product, the core was exposed on the outer surfaces of the handles 4a to 4e in order to hold the core in the mold. Until now, there was no meaning other than merely accents of the patterns 4a to 4e. However, marks 7a to 7c imitating the shapes of the blades 3a to 3e are provided on the respective exposed portions 6a to 6e.
Since 7e is formed, the exposed portions 6a to 6e essential for the double molded product can be effectively utilized.

2) For example, in the conventional chisel 30 as shown in FIG.
When it is formed, it simply becomes a relief shape,
It is difficult to see at a glance. However, in this embodiment, since the core body and the outer jacket 5 of the elastomer are separate bodies, the colors of both can be changed. Therefore, the marks 7a to 7e are
Therefore, it is possible to form the semiconductor device more raised.

3) Each exposed portion 6a-of the chisel 1a-1e
6e is located near the base end of the handles 4a to 4e.
In the state of being housed, the marks 7a to 7e near the base end thereof can be visually recognized from the window portion 20 on the front surface of the fitting portion 18. Therefore, the desired chisel 1a to 1e can be obtained without checking the blades 3a to 3e.
Can be taken out.

4) When stored in the storage case 2 after use, the stamps 9a to 9e formed on the contact plate 16 and the handles 4a to 4
Which chisel 1a is used to match the mark 7a to 7e
1e can be customarily recognized in which accommodation hole 9 should be accommodated. Therefore, the desired chisel 1a to 1e can be quickly taken out in combination with the marks 7a to 7e.

It should be noted that the present invention is not limited to the above embodiment, but may be configured as follows without departing from the spirit of the present invention. (1) Mark 7 provided on handles 4a-4e of chisels 1a-1e
a to 7e are formed by penetrating the handles 4a to 4e.
The blade shape may be confirmed from the front and back of a to 1e. In this case, since a through hole is formed, as one of the methods of using the chisel, the handles 7a to 7a are used.
A string can be passed through the base end of 7e, and the string can be closed in a ring shape and hung on a finger for auxiliary use.

(2) In the present embodiment, the housing hole 9 is formed in the case main body 10 in a partitioned manner, but the housing body may not be completely partitioned, and may be a storage section provided with upper and lower partitions. (3) The number of chisels 1 to be accommodated may be two or more.

[0022]

As described in detail above, in the invention of the first aspect, a mark imitating the shape of the blade body is formed on each exposed portion, so that the exposed portion of the core in the double molded product can be effectively used. By utilizing this, it is possible to easily identify and select a chisel having a desired blade.

In the invention of claim 2, in addition to the effect of the invention of claim 1, since the mark is engraved in a concave shape, it can be used as a holding portion at the time of double molding. According to the invention of claim 3, in addition to the effects of the invention of claim 1 or claim 2, for example, when the chisel is stored in a state where the tip of the handle with the blade body is hidden in the chisel case. However, if the base end portion of the handle with the mark is out of the case, a desired chisel can be easily identified and selected.
