RU208514U1 - VIBRATION PROTECTIVE GLOVE - Google Patents

Abstract

The utility model relates to the production of personal protective equipment, in particular to garments designed to protect the user's hands, namely vibration-proof gloves. The vibration-protective glove is equipped with a vibration-absorbing insert 3 fixed on the wrong side of the glove, while said insert 3 is made of sheet material and corresponds to the shape of the palm and fingers. On the vibration-absorbing liner 3, on the side adjacent to the glove, transverse grooves 4 are made. These grooves 3 reduce the stresses that occur in the liner when the hand is bent to grip objects.

Description

The technical field to which the utility model belongs

The utility model relates to the production of personal protective equipment for a person, in particular, to garments designed to protect the user's hands, namely, vibration-proof gloves.

State of the art

Vibration-resistant gloves are personal protective equipment designed to reduce to a safe level the degree of local vibration that affects the user's hands during work. Vibration-resistant gloves are used when handling tools and machines containing hydraulic, pneumatic or electric drives. The upper part of the gloves, as a rule, is made of natural or artificial leather, synthetic, cotton or blended knitwear, synthetic, cotton or blended fabrics. Fabric or knitwear can be coated with PVC, natural or nitrile butadiene latex, silicone, etc. In the production of vibration damping elements, vibration-absorbing chloroprene foam and other polymeric materials such as rubber, rubber and layered raw materials based on them, as well as various gel materials are used. compositions based on PVC or silicone. These materials are capable of dissipating external acoustic energy.

Gloves and mittens for simple household work protect hands from vibration and mechanical damage. Such protective equipment can be made of high quality natural leather and have cuffs to protect the wrists. Professional products are distinguished by a high degree of vibration protection and resistance to various mechanical influences (abrasion, cut, tear and puncture).

There are many varieties of anti-vibration gloves designed for both household and professional use.

From the prior art, vibration-resistant gloves are known which are sewn. The palm part of these gloves is equipped with a vibration-absorbing foam rubber element. The vibration-absorbing element is made in the form of an insert fixed on the seamy side of the gloves (see utility model patent RU 185251, published on November 28, 2018).

Also known is a vibration-protective glove, the palmar part of which is equipped with a vibration-absorbing element made in the form of an insert placed on the seamy side of the glove. The specified insert is made of sheet material and corresponds to the shape of the palm and fingers, while the cut lines of the sheet material in the area corresponding to the fingers of the hand between the little finger, ring, middle and index fingers have a shape that alternately deviates on both sides with respect to imaginary lines corresponding to the boundaries between adjacent fingers (see utility model patent RU 204754, publ. 06/08/2021).

Inside such gloves, on the palm part, there is a vibration-insulating liner made of foam rubber sheet. The liner has the same thickness over the entire plane.

The disadvantage of this design is the significant stresses arising in the liner when bending the hand to grip objects: tools, parts, etc. In addition to the force required to hold the objects, the user has to apply additional force to overcome the stress in the liner material, which can provoke fatigue.

Disclosure of a utility model

The technical problem to be solved is the manufacture of vibration-protective gloves, the vibration-absorbing liner of which does not require additional efforts to overcome the stress in the liner material, which can provoke fatigue during their operation.

According to the utility model, the vibration-protective glove is equipped with a vibration-absorbing insert fixed on the wrong side of the glove. The specified insert is made of sheet material and conforms to the shape of the palm and fingers. On the vibration-absorbing insert from the side adjacent to the glove, grooves located transversely relative to its longitudinal axis are made.

These grooves can be located both parallel and at an angle to each other.

The width of the grooves is preferably 2-10 mm.

The grooves are made to a depth of 10-90% of the thickness of the vibration-absorbing insert.

The grooves can be straight and / or curved in different areas of the insert.

The technical result from the use of the utility model is to reduce the stresses arising in the liner due to the grooves made located across the longitudinal axis of the liner (across the fingers and palm). The grooves create additional space for the liner to compress. Thus, the user does not need additional efforts to overcome the resistance of the liner to bending, which saves energy and provides a higher level of comfort and safety.

Brief Description of Drawings

The utility model is illustrated by drawings, where:

in fig. 1a and 1b are plan and side views of a vibration-absorbing insert of a vibration-resistant glove known from the prior art;

in fig. 2 - vibration-absorbing liner in a compressed state with the shown layer with high stresses in it;

in fig. 3a and 3b show plan and side views of a vibration-absorbing insert of a vibration-resistant glove according to the utility model;

in fig. 4 - a vibration-absorbing insert of a vibration-protective glove according to the utility model in a compressed state.

Implementation of the utility model

FIG. 1a, 1b and 2 are plan and side views of a vibration-absorbing insert 1 of a vibration-protective glove known from the prior art, as well as a vibration-absorbing insert 1 in a compressed state with the shown layer 2 with high stresses therein. The vibration-absorbing insert 1 of the vibration-proof gloves is made of sheet material. The shape of the earbud generally follows the shape of the palm and fingers. The disadvantage of this design is the significant stresses arising in the liner when bending the hand to grip objects: tools, parts, etc. In addition to the force required to hold the objects, the user has to apply additional force to overcome the stress in the liner material, which can provoke fatigue.

A vibration-proof glove according to the invention, as shown in FIG. 3, is provided with a vibration-absorbing insert 3, fixed on the wrong side of the glove, while said insert 3 is made of sheet material and corresponds to the shape of the palm and fingers. On the vibration-absorbing insert 3 on the side adjacent to the glove, grooves 4 located transversely relative to its longitudinal axis are made.

The material of the insert 3 can be foam rubber of various compositions, polyurethane foam, polyethylene foam, ethylene vinyl acetate and other foamed sheet materials.

It is preferable to make flat liners by cutting out of sheet material. These can be various sheet materials.

The required reduction of stresses arising in the liner during its compression is provided by grooves 4 located across the longitudinal axis of the liner (across the fingers and palm). The width of the grooves can be from 2 to 10 mm, the depth is from 10 to 90% of the liner thickness. The grooves can be cut both parallel and at an angle to each other, can be straight or curved.

The liner, depending on the material from which it is made, can be attached to the glove in different ways. It can be fixed pointwise, along the contour or along the area, it can be sewn into a textile or knitted cover, which in turn is attached to the glove. Securing can occur by gluing, sewing, or other methods, including a combination of different methods.
