Description

[Detailed description of the invention] This invention relates to the handle of a tool such as a screwdriver. In other words, the handle of a screwdriver, etc. is usually formed into a rod shape of wood or hard synthetic resin, etc. in order to make it easy to grip. It has several grooves to prevent it from slipping, but these grooves can dig into the palm of your hand, causing pain if you use it for a long time or grip it too tightly.

Therefore, as a countermeasure to this problem, if a band-shaped rubber material with a large frictional coefficient is buried in the groove provided on the outer surface of the handle by baking or other means, the rubber material is likely to peel off. Furthermore, with the method of fitting a cap-shaped anti-slip cap with unevenness on the outer surface from the end to the outer periphery of the handle, there is a drawback that the outer cap may rotate or come off during use. If it is covered, the outer surface of the handle will be covered, weakening the grip on the handle.

The present invention addresses this problem, namely, a plurality of grooves are formed on the outer periphery of the handle body at appropriate intervals in the circumferential direction and have a length that does not reach both ends in the axial direction. They are communicated by a cavity penetrated through the inside of the core, and elastic anti-slip materials made of rubber, synthetic resin, etc. are interconnected and embedded in each groove and cavity, and the outer surface of the anti-slip material is It is characterized by the above-mentioned grooves being raised toward the outside of the handle body.

Below, this will be explained using the example shown in the figure.
is the handle body of the tool, which is mainly formed into a desired shape from wood or hard synthetic resin, etc., and has a plurality of cutting grooves 2 formed at appropriate intervals in the circumferential direction and in a range that does not reach both ends in the axial direction. Along with
The respective kerfs 2 are communicated with each other through a cavity 6 which is provided so as to pass through the inside of the shaft center of the handle body 1. In Figs. 1 to 4, the above-mentioned cavities 6 are shown extending through the opposite ends of the kerfs 2, but as shown in Fig. 5, the cavities 6 extend over the entire length of each kerf. It may also be provided. 3 is a tool rod which is protruded by embedding its base in the tip of the main body 1; 4 is a tool rod made of rubber, synthetic resin, etc. having appropriate elasticity and embedded in the cut groove 2 and the cavity 6 so as to be interconnected with each other; This anti-slip material has a mountain-shaped bulge 4' on the outer surface thereof extending outward from the handle body 1 from each groove 2. Therefore, the anti-slip material 4 in the cavity 6 assumes a columnar shape 5a in the cavity when the cavity 6 is provided independently at both ends of each groove 2 as shown in FIGS. 1 to 4. In the example shown in FIG. 5 in which the cavity 6 is provided over the entire length, it has a plate shape 5b. The above-mentioned cavity 6 has four kerfs 2 in the figure, so its cross section is cross-shaped, but with three kerfs it becomes Y-shaped, and this cross-sectional shape differs depending on the number of kerfs 2. In either case, they will be continuous within the axis of the handle body.

With the above configuration, when the handle body 1 is grasped and screwed together, elastic anti-slip material is bulged out on the outer surface of the body in the axial direction at appropriate intervals in the circumferential direction. Therefore, the hand is prevented from rotating while maintaining a good texture, and during this operation, the palm of the hand comes into contact with the outer surface of the handle body 1 itself in addition to the above-mentioned anti-slip material. Therefore, the main body can be gripped tightly and the main body can be strongly turned.

As described above, according to the present invention, the anti-slip material protrudes outward from the several grooves provided on the handle body, which eliminates slippage during rotation, and also prevents slipping during rotation. The anti-slip material is interlocked with each other in the cavity that passes through the shaft of the handle body, so it does not peel off or fall off, and does not rotate relative to the handle body.
Moreover, since the palm of the hand that grips the handle body comes into contact with the outer surface of the body itself, a strong grip is possible, and the rotational operation of the screwdriver can be performed safely and efficiently.
