Abstract

(57) [Summary] [Object] To provide a handle retaining structure that is safe and easy to manufacture in Genno. [Structure] A pin body 3 which is fitted through a hammer body 1 and a handle 2 in a hole portion 12 and is prevented from coming off by caulking at a tip portion.
In order to keep the handle.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a connection structure between a hammer body and a handle in Genno and various other mallets.

[0002]

[Prior art]

 As is well known, a hammer such as Genno consists of a hammer body of a predetermined shape and a wooden handle, a resin handle, or a metal pipe handle. Since the tip of the handle is inserted and the hammer is swung in use, appropriate retaining means are provided from the viewpoint of safety.

[0003] As a conventional handle retaining means, a wedge is driven from a tip end face of a wooden handle inserted into a hole, and a side surface of the handle strongly presses a side wall of the hole, and a side surface of the handle and a side surface of the hole. An attachment means using an adhesive such as a bond between the handle and an L-shaped fitting attached to the side of the handle, the fitting is connected to the handle with a nail, and the tip of the fitting is hooked on the upper surface of the hammer body. Means are known.

[0004]

[Problems to be solved by the invention]

 There are various problems with the handle retaining means. The wedge means is easy to come off or loosen, and there is a risk that the handle may come off suddenly, which poses a safety problem.

[0005] Furthermore, the bonding means requires a treatment for pouring the adhesive into a narrow place and preventing the adhesive from flowing out to the hand side of the handle, which is inefficient in production. Further, the means for using the metal fittings requires metal fittings, and there is a problem in use such that the connecting portion is immediately loose and the nails are easy to float. Therefore, the present invention proposes a new retaining means.

[0006]

Means for Solving the Problems A hammer according to the present invention is composed of a hammer body having a handle insertion hole which is open at least on the bottom surface, and a rod-shaped handle having a tip portion inserted into the insertion hole. The hammer of the present invention is characterized in that the hammer is provided with a structure for preventing the hammer from being detached from the hammer by attaching a fastening member that reaches at least the handle in the hole from the side surface of the hole forming portion.

[0007]

[Action]

 Since the hammer body and the handle are connected by the fastening member, the handle does not come off. In addition, the impact force of the handle in the direction of handle withdrawal and the impact of the hammer during use acts at right angles to the axial direction of the fastening member. It can withstand change.

【Example】

 Next, an embodiment of the present invention will be described. <First Embodiment> FIGS. 1 to 3 show a first embodiment of the present invention. This embodiment is an example of a tile hammer using a wood screw as a fastening member.

The Genno shown in the embodiment is composed of a hammer 1, a handle 2 and a pin 3, and the hammer 1 has a striking surface 11 at both ends and is fitted with a handle vertically penetrating the center. In addition to providing the hole 12, a pin hole 13 penetrating the left and right of the hammer 1 at the top and bottom and the front and rear centers of the hole 12 is formed. It is formed in the shape of a dish or steps.

The handle 2 is made of wood, and has a shape in which an upper end portion can be tightly inserted into the hole 12, and a pin hole 21 is formed at a position corresponding to the pin hole 13. The pin body 3 is closely inserted into the pin holes 13 and 21.

The Genno of the present invention is that the tip of the handle 2 is inserted into the hole 12, the pin 3 is inserted into the communicating pin holes 13, 21, and the end of the pin 3 is swaged to integrate the three members. That is.

Accordingly, when the handle 2 is gripped and used, the impact caused by the impact of the hammer 1 and the swinging of the handle 2 all act at right angles to the axial direction of the pin body 3. The pin body 3 is not detached from the hammer body 1 and can withstand sufficient use. In particular, when the side surface of the hammer body 1 is polished after caulking the pin body 3, the pin body 3 becomes inconspicuous and Also, there is no need for finishing after caulking, and the production can be easily performed.

Second Embodiment FIGS. 4 and 5 show a second embodiment of the present invention. This embodiment is an example of a hammer using a wood screw as a fastening member.

The hammer shown in the embodiment is composed of a hammer 1a, a handle 2a, and a wood screw 3a. The hammer 1a has one end as a tile splitting beak 14 and the other end as a hitting surface 15. In a known shape, a hole 16 for inserting a handle with an open bottom surface is provided at the center in the front-rear direction, and a screw hole 17 reaching the hole portion 16 at the center of the hole 16 at the top and bottom and in the front-rear direction. The end portion of the screw hole 17 is formed in a dish shape or a step shape corresponding to the head of the wood screw 3a.

The handle 2a is made of wood, and the upper end portion is formed so as to be able to be inserted tightly into the hole portion 16. The tip portion is inserted into the hole portion 16 and the wood screw 3a is inserted through the screw hole 17 into the hole portion 16. It is screwed into the inner handle 2a to integrate the hammer 1a and the handle 2a.

Accordingly, when the handle 2a is gripped and used, the impact caused by the impact of the hammer 1a and the swinging of the handle 2a all act at right angles to the axial direction of the wood screw 3a. It is not detached from the hammer 1a and can withstand use sufficiently, and can be manufactured simply by simply screwing the wood screw 3a.

The present invention is not limited to the above-described embodiment. The hammer may be of any type, such as one having a nail at one end or a beak at both ends. The insertion hole may be a through hole or a non-through hole, and the handle may be made of reinforced resin as well as wooden. Of course, the fastening member may be a pin body with a crimped head, a shaft body with an adhesive applied to the surface, or a through bolt.

[0018]

[Effect of the invention]

 As described above, according to the present invention, the connection between the hammer and the handle of the hammer is made by attaching a fastening member that reaches at least the handle in the hole from the side of the hammer to prevent the handle from coming off from the hammer. With this structure, a safety structure can be provided that ensures sufficient safety during use and that is easy to manufacture.
