Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a grip for a power tool such as an electric drill, and particularly to a grip provided with a non-slip grip.

[Wtam] The housing of a power tool is made of metal or hard synthetic resin. For this reason, the surface is quite slippery, so to prevent slipping, the grip on the housing has a low-left finish on its surface, or has irregularities created when the housing is molded. Even if you grip the grip firmly when working, it may slip if your hands are sweaty or you are wearing gloves, making it impossible to reliably transmit the mechanical force to the power tool, and reducing work efficiency. Not only do they fall, but they sometimes drop the power tool and damage it.

[Objective of the Invention 1] The present invention has been made in view of the above points, and its purpose is to provide a grip for a power tool that has a high anti-slip effect and that can reliably transmit operating force. It is on offer.

[Disclosure of the Invention] The present invention provides a grip that protrudes from the main body of a housing which has a tool attachment chuck at its tip and houses a drive motor therein, and which has a front lower part on the chuck side. The grip is characterized by an elastic body protruding from the grip surface being provided at the rear upper end, so that the fingers of the hand holding the grip come into contact with the elastic body.

The present invention will be described in detail below based on the illustrated embodiments.
5 to 5 show one embodiment, and the housing 1 is composed of a main body body 2 and a grip 3 projecting downward from the rear end of the main body body 2. A chuck 10 for attaching a tool such as a drill bit or a driver bit is disposed at the tip of the body body 2 in which a motor and the like are housed. 11 is a switch handle, and 12 is a lock button.

The grip 3 in this power tool is formed integrally with the main body 2, and the lower parts of both front sides, which are the chucks, and the upper ends of both rear sides are made of elastic material. 4 is attached. This elastic material 4 is formed by so-called two-color molding using a plurality of holes 15 that penetrate the grip 3 and have a diameter on the inner side of the grip 3 larger than that on the surface side. ,
Consisting of a penetrating portion 5 of each hole 15 and a linear connecting portion 6 that connects the penetrating portions 5 lined up in a row on the surface side of the grip 3,
The connecting portions 6 provided in a plurality of rows are formed as protrusions that protrude from the surface of the grip 3 and are parallel to the longitudinal direction of the grip 3.

However, with lever grip 3, when you squeeze it, the 5th
As shown in the figure, the pad of the thumb is in contact with the elastic material 4 provided at the upper rear end of the grip 3, and the pads of the other fingers are in contact with the elastic material 4 provided at the lower front portion of the grip 3. Because the elastic material 4 protrudes from the surface of the grip 3, the grip 3 can be held securely.

7 and 158 show that the grip 3 of the housing 1 is provided protruding from the middle of the main body body 2, and in this case, the grip 3 has a lower part on both front sides and an upper end on the rear side. Elastic members 4 similar to those shown in the above embodiment are attached to both sides. In this embodiment, since the switch handle 11 is disposed at the upper front end of the grip 3, the pad of the thumb touches the elastic material 4 disposed at the upper rear end of the grip 3, and the pad of the index finger comes into contact with it. The base is in contact with the other fingers, and the lower front side of the grip 3 is in contact with the other fingers. Then, the grip 3 can be held reliably, and the operating force can be reliably transmitted to the grip 3.

FIG. 8 and subsequent figures show the structure inside the grip 3 in the embodiment shown in FIGS. 1 to 5. A storage battery 20 serving as a power source is housed in the front part of the grip 3, and a driver bit 21 as a tool is housed in the rear part while being held by a holder 22. As shown in FIG. 9, the holder 22 here has two cylindrical parts 23 and 23 into which the driver bit 21 is inserted, and a fixing piece 24 and a cover 25 are integrally formed. The fixing piece 24 and cover 2
5 by a thin hinge piece 26. The connecting portion between the fixed piece 24 and the holder 22 is also the same (a thin hinge piece 27).

The fixing piece 24 is attached to the grip 3 by being inserted into a fixing groove 30 formed on the inner surface of the split grip 3, and the holder 22 is also formed on the inner surface of the grip 3, as shown in FIG. It is held by the lip groove 31 that has been formed. The fixing piece 24 is fixed by the hinge piece 26.
The cover 25 is rotatable relative to the grip 3.
It functions as a pot for closing an opening for taking out bits formed at the lower end of the rear side, and has seven hooks 28 that are engaged with the grip 3.

The driver bit 21 can be taken out or stored by opening the cover 25.
5 does not come off from the grip 3,
This prevents the cover 25 from being lost. Furthermore, in the holder 22 here, a pair of cylindrical portions 23, 23 into which the driver bit 21 is inserted,
As shown in FIG. 11, the driver bit 21 is formed to be offset in the ring direction, and the cylindrical portion 23°23
Since the screwdriver bits 21 inserted in the screwdriver bits 21 are also held in a shifted state, it is easy to take out the two driver bits 21 that are lined up.

[Effects of the Invention] As described above, in the present invention, since the elastic material protruding from the surface of the grip is attached to the part of the grip where the fingers rest, it is possible to securely hold the grip without slipping. , it is possible to reliably transmit operating force to the grip, improving work efficiency and safety.
