Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a grip that can be tightened during operation.

[Conventional technology and its problems]

In general, when manually operated vibrating tools such as concrete breakers and grinders are used for long periods of time, blood circulation is impaired, the skin temperature of the hands and fingers decreases, and there is an extremely high risk of contracting white wax. Therefore, although manufacturers are making efforts to dampen the vibrations of vibrating tools, there are limits and it is impossible to completely eliminate vibrations.

In order to damp the vibrations of vibrating tools, vibration-proofing grips and anti-vibration grips are available in which an elastic body is wrapped around the grip or an elastic body is interposed between the surface layer and the core of the grip so that the elastic body absorbs the vibrations. Although waving gloves and the like have been proposed, all of them have the disadvantage that they only slightly attenuate high-frequency vibrations, but hardly attenuate low-frequency vibrations that cause leukemia.

By the way, far infrared rays, which have been in the spotlight in recent years, are
Because it is a radiation that appears in the long wavelength range of the infrared region and has a strong thermal effect, it is being widely developed mainly in the fields of heating and drying. This far infrared rays
Because it is a low frequency, it penetrates deeply into the body through the skin of the body, and from the muscle layer on the body surface, the blood vessels,
It is known to have an even heating effect on all cells, including lymph vessels and nerves, and is effective in relieving stiff shoulders and lower back pain.

Therefore, by emitting far infrared rays from the grip of a vibrating tool, it is possible to improve blood circulation in the hands and fingers, prevent white wax, and reduce fatigue.

Therefore, the purpose of this invention is to provide a grip that is effective in preventing white wax and reducing fatigue.

[Means for solving problems]

In order to achieve the above object, this invention has a configuration in which a far-infrared radiator is provided on the surface layer of the grip body.

[Effect]

With the above configuration, the grip is warmed by the temperature, perspiration, or friction of the fingers holding the grip, and the far-infrared rays are emitted from the far-infrared radiator. Because the far infrared rays penetrate deeply into the body,
The warming effect of far infrared rays promotes blood circulation and can prevent white wax.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIGS. 1 and 2, the surface of the grip body 1 is provided with an overcoat layer 2 made of synthetic resin, rubber, or the like. This overcoat layer 2 has protruding far-infrared radiators 3.
is supported, and a portion of the radiator 3 is exposed from the surface of the overcoat layer 2.

Here, as the far-infrared radiator 3, ceramics or activated carbon can be used.

FIG. 6 shows grip A consisting of the above configuration.
An example of installation on concrete breaker 11 is shown,
Further, FIG. 7 shows an example of use in the grinder 12. As mentioned above, by providing the far infrared ray emitter 3 on the surface layer of the grip A, the grip A
The grip warms up due to the temperature of the fingers holding the grip and sweat, and far infrared rays are emitted from the far infrared ray emitter 3.

Here, as mentioned above, far-infrared rays have the property of penetrating into the body through the skin and have a thermal effect, so the far-infrared rays emitted from the far-infrared radiator 3 promote blood circulation in the hands and fingers, thereby preventing white wax. can be prevented.

Further, as shown in FIGS. 1 and 2, a part of the granular far-infrared radiator 3 is removed from the overcoat layer 2.
By exposing it in dots from the surface of the finger, an effect similar to acupressure can be imparted to the fingers.

Generally, the casing of an air hammer, an air motor, or the like that is a driving source for vibration-proof tools such as the concrete breaker 11 or the grinder 12 is likely to freeze due to adiabatic expansion of exhaust gas. Therefore, as shown in FIG. 7, by covering the driving part of the casing with the overcoat layer 2 provided with the far-infrared ray emitter 3 and gripping that part, heating of the far-infrared rays emitted from the far-infrared ray emitter 3 is performed. This makes it difficult for condensation to form.
The efficiency of the vibrating tool can be stabilized.

The above-mentioned far-infrared radiator 3 may be made into particles and inserted into the grip body 1 as shown in FIG. 5, or as shown in FIG.
The overcoat layer 2 may be formed as a powder.

As shown in FIG. 4, by providing an overcoat layer 2 made of a powdered far-infrared radiator 3 on the surface of the grip body 1, which has an elastic body 5 provided around a core bar 4, vibrations transmitted to the grip body 1 are provided. The elastic body 5 absorbs the vibrations to alleviate the vibrations, and the vibrations generate frictional heat, which warms the far-infrared radiator 3, thereby promoting the emission of far-infrared rays.

Furthermore, as shown in FIGS. 3 and 4, by forming the overcoat layer 2 made of the far-infrared radiator 3 on the grip body 1, the surface of the overcoat layer 2 is made rough. , can be effective in preventing slipping.

In the embodiment, only the grip of a vibrating tool has been described, but the radiator may be provided on an automobile handle or its surface.

〔effect〕

As mentioned above, this invention provides a far-infrared ray emitter on the surface of the grip body, and the far-infrared rays emitted from the far-infrared ray emitter can promote blood circulation in the fingers. It is effective in preventing deafness and reducing fatigue, and can withstand long-term use.

Furthermore, since protrusions or powder can be used as the far-infrared radiator, it is possible to impart an effect similar to acupressure or a non-slip effect to the grip, improving workability and safety. .
