Abstract

(57) [Summary] [Object] To provide a hammer in which a gripping body having flexibility or elasticity is firmly held by a hammer shaft. A hammer in which a gripping body 3 having flexibility or elasticity is fitted to a base end portion of a hammer shaft 2 provided on a hammer head 1, and the base end portion of the hammer shaft 2 is formed to be slightly thicker toward the rear side. A hammer having an insertion section 2'having an elliptical cross section with the major axis made vertical and provided with a plurality of retaining locking projections 4 at predetermined intervals above and below the insertion section 2 '.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hammer.

[0002]

[Problems to be solved by conventional techniques and devices]

 In order to make it easier to grip a hammer that hits nails or tacks, a hammer in which a flexible or elastic gripping body is fitted to the base end of the hammer shaft is often used. Due to the inertial force of the hammer and the driving force, the adhesive may lose its effect during use and the grip may fall out of the hammer shaft, which was dangerous.

The present invention provides a hammer that solves the above drawbacks.

[0004]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A hammer in which a gripping body 3 having flexibility or elasticity is fitted to a base end portion of a hammer shaft 2 provided in a hammer head 1, and the base end portion of the hammer shaft 2 is slightly thicker toward the rear side. The present invention relates to a hammer, which is formed and provided with a plurality of retaining locking projections 4 at a predetermined distance.

Further, in a hammer in which a gripping body 3 having flexibility or elasticity is fitted to a base end portion of a hammer shaft 2 provided in a hammer head 1, the base end portion of the hammer shaft 2 is moved rearward. Forming a slightly thicker insertion portion 2'having a longitudinal axis of an elliptical shape and having a plurality of retaining locking projections 4 facing each other at predetermined intervals above and below the insertion portion 2 '. The present invention relates to a hammer characterized by.

[0007]

[Operation] Since the proximal end of the hammer shaft 2 is formed slightly thicker toward the rear and a plurality of retaining locking projections 4 are provided at a predetermined distance, the hammer shaft 2 can be removed from the grip body 3. Hold firmly.

The base end of the hammer shaft 2 is formed slightly thicker toward the rear to form an insertion portion 2 ′ having an elliptical cross section with a longitudinal axis being vertical, and a plurality of insertion portions 2 ′ are provided above and below the insertion portion 2 ′ with a predetermined interval. Since the individual withdrawal stop engaging projections 4 are provided in a pair, the hammer shaft 2 can be securely pulled out from the grip body 3.

[0009]

【Example】

 The attached drawings show that a pipe-shaped hammer shaft 2 is connected in a T-shape to a hammer head 1 having a striking face portion and a nail pulling portion of a preferred embodiment of the present invention, and the hammer shaft 2 has a flexible end portion. Alternatively, a hammer to which an elastic gripping body 3 is fitted is shown.

In parallel with the striking face portion and the nail pulling portion of the hammer head 1, a base end portion of the hammer shaft 2 is formed to be slightly thicker toward the rear to form an insertion portion 2 ′ having an elliptical cross section with a longer major axis. A plurality of retaining locking projections 4 having a predetermined length are provided opposite to each other at a predetermined interval above and below the long diameter portion of the insertion portion 2 '.

Since the embodiment of the present invention is configured as described above, when the grip body 3 is gripped and the hammer head 1 strikes a nail or a tack, the hammer shaft 2 is formed to be slightly thicker toward the rear of the base end portion thereof. The insertion portion 2'having an elliptical cross section prevents the hammer shaft 2 from coming off so that it opposes the inertial force of the hitting of the hammer head 1, and the locking projections 4 above and below the insertion portion 2'are flexible or elastic. The hammer shaft 2 is firmly held by the gripping body 3 because the hammer shaft 2 is prevented from rotating and coming off by coming into contact with the fitting portion of the gripping body 3 having the above.

[0012]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is an excellent hammer that is easy to grip and has a simple structure that firmly holds the hammer shaft and the gripping body against rotation and withdrawal, and does not require an adhesive.
