Abstract

(57) [Summary] [Purpose] To create a hammer that absorbs the sound of hitting the pile head and prevents detection by the opponent as much as possible. [Structure] Hard synthetic resin pieces or synthetic rubber pieces with a smooth striking surface are attached to both ends of the hard metal hammer body into which the wooden handle is fitted.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention absorbs the sound of impact against the pile head when burying retaining piles for use in camouflage nets, etc. This invention relates to a sound-absorbing hammer that can prevent detection by the other party as much as possible.

0002

[Conventional technology]

Conventionally, this type of retaining pile was completely buried so that it could be inserted into solid ground. A hammer with a body made of metal such as iron was used. However, with a metal hammer, Since the sound of impact against the pile head resonates loudly in the surrounding area, there are various types of equipment that are covered with camouflage nets etc. The location of materials, etc. will be easily detected by the other party, and it will be difficult to use during outdoor activities. It was extremely inappropriate.

0003

[Problem that the idea aims to solve]

This invention replaces a part of the metal part with a piece of hard synthetic resin or piece of hard synthetic rubber. The impact sound generated when hitting the head is absorbed into the hammer itself as much as possible, and the hammer The aim is to reduce the noise generated based on

0004

[Means to solve the problem]

This invention combines a metal hammer body with a wooden handle and a new smooth so as to be positioned between the hard synthetic resin piece or the hard synthetic rubber piece that has a striking surface. The entire hard synthetic resin or hard synthetic rubber piece at the tip directly absorbs the impact on the striking surface. It also transmits the damped impact sound to the metal hammer body, and the final The wooden handle has a structure that further increases the absorption and relaxation effect, and it also has a pile cap that is necessary for the striking surface. Provide a sound-absorbing hammer such that the pressure against the hammer is sufficiently compensated for throughout the hammer. It is something.

Figure 1 is an explanatory side view of the product of the present invention, and Figure 2 is the hammer body and hard joint of the product of the present invention. It is an explanatory view showing a connection mechanism with a plastic piece or a hard synthetic rubber piece. Code 1 is sound absorption 2 is the hammer body, 3 is a piece of hard synthetic resin or synthetic rubber, and 4 is the handle. part, 5 is a connecting male part embedded in a synthetic resin piece or synthetic rubber piece, and 6 is a connecting male part inserted into it. The connecting female part is shown to be drilled into the hammer body for use.

[0006] The sound absorbing hammer 1 according to the present invention includes a hammer body 2, a synthetic resin piece 2 a synthetic rubber piece 3. and a handle portion 4. The hammer body 2 is made of hard metal, usually iron, but it also retains striking force. In order to reduce the weight of the hammer as much as possible, the left and right sides of the main body can be recessed. Ru. The synthetic resin piece or synthetic rubber piece 3 has appropriate hardness and abrasion resistance, and is resistant to impact. The material is selected from materials that effectively absorb the impact noise generated. These synthetic resin pieces When the synthetic rubber piece 3 is molded by casting etc., the connecting male part is buried and only the threaded part is exposed. the male part is screwed into the connecting female part 6 bored at the tip of the hammer body 2. Securely fix both. If the synthetic resin piece or synthetic rubber piece 3 is worn out, replace it. is freely possible.

[0007]

[Effect of the idea]

The present invention is based on the above configuration, and the striking surface is based on the weight of the hammer. The impact sound generated by the impact is absorbed by the synthetic resin piece or synthetic rubber piece at the tip. Therefore, it is necessary to maintain confidentiality and silence to the maximum extent possible. It is extremely useful for staking out camouflaged nets.
