Description

Shock-absorbing gloves with various thicknesses of padding

Technical field

The invention relates to a labor protection material, in particular to a personal protection equipment, which can effectively reduce the modulus of elasticity, reduce vibration, and improve the protective effect. The material is made into shock-absorbing gloves, which can reduce the vibration of workers during work , In order to reduce the damage caused by vibration to blood vessels, bones and nerves.

Background technique

The use of hand-held vibration tools is very common, and prolonged use may cause serious injuries, such as arm vibration syndrome. When the hand system is forced to vibrate, the response of different parts of the arm system is different, and for different frequencies, the response is also different. Resonance in different parts of the hand-arm system is considered to have a continuous correlation with injuries.

In many countries in the world, more than 10% of workers are using vibration tools for more than 2 hours a day. This damage does not happen immediately, but over time, the vibration will cause serious damage to the opponent’s nerves, blood vessels, muscles and bones. This kind of damage is called Hand Arm Vibration Syndrome.

The vibration isolation function of the flexible compressible liner, such as increasing the thickness, improving the softness and mechanical loss factor, makes the vibration gloves protect the opponent. Thicker and softer materials can increase isolation performance and reduce the inherent resonance frequency of the tool/glove/hand system.

A particular problem is that the weight of the fingers is lighter than the palm, which makes the vibration frequency of the fingers higher than the palm area, which increases the risk of injury. The vibration frequency is directly proportional to the square root of the stiffness of the material and inversely proportional to the weight of the material, as shown by the formula ω _n =(k/m) ^1/2 . Among them, ω _n represents the angular velocity (radians per second), k represents the stiffness of the material (N/m), and m represents the mass (kg).

The efficiency of isolation is judged by the transmission factor (T), which is the ratio of the acceleration of the hand in the glove to the acceleration of the tool. T greater than 1 indicates that the acceleration is amplified (amplification of the acceleration), T equal to indicates no effect, and T less than 1 indicates that the acceleration is reduced (reducing acceleration).

The protective effect of gloves depends on a large number of external factors, rather than frequency, such as: pushing (feeding) force, grip strength, individual differences (such as: the quality and rigidity of the operator's hand, and the operator's bones), tool types and work Conditions etc.

Take the anatomy of the fingers as an example. The palms and fingers of different specifications and weights will cause different parts of the hand to produce different natural resonance frequencies in the tool/glove/hand system. Especially slender fingers (such as the little finger and ring finger) and the fingers close to the fingertips usually produce higher resonance frequencies, and therefore it is more difficult to protect them.

Chinese invention patent application 201110219663.9 discloses a glove to reduce vibration, including a glove body, which includes a finger part, a palm part, a back part and a wrist part. The palm part is provided with a thickened pad a, a thickened pad b, and a thickened pad c. , The thicker pad a is located on the palm part near the finger part, the thicker pad b is located on the palm part near the thumb part, and the thicker cushion c is located on the palm part near the underside of the little finger, and the wrist part is made of lap and nylon The thickened pad a is a breathable layer, the thickened pad b is a non-slip, wear-resistant and seismic layer, and the thickened pad c is a seismic and wear-resistant layer. In the case of strong earthquakes, it can effectively protect the hand joints or reduce the degree of injury in the event of an accident, and play a good protective effect on the user’s hand joints. The structure is reasonable, comfortable to wear, and effective. It is suitable for strong Shocking work or recreational activities.

When the hand is exposed to forced vibrations, different parts of the arm system are subject to resonance. For example, the resonance frequency of the upper arm is about 10 Hz, the palm and wrist are about 20 Hz to 30 Hz, and the resonance of the fingers is about 100 Hz to 300 Hz. As we all know, the greatest damage to tissues due to force is at the resonance frequency. Compared with the middle part of the finger, the resonance frequency of the fingertip is higher, and compared with the base of the finger, the resonance frequency of the middle part of the finger is higher. Compared to shorter and thicker fingers, longer or thinner fingers have a higher resonance frequency.

The resonance frequency of the arm system also changes with the grip strength. Generally speaking, the greater the grip strength, the higher the resonance frequency. The transmission of forced vibration acceleration is extremely related to resonance. At the resonance frequency, it reaches the highest value and decreases as the frequency increases.

EN/ISO 10819: 2013 is an international standard that regulates anti-vibration gloves. In this standard, it only measures the vibration transmission on the palm. The standard further states that the seismic material must be uniform in characteristics and thickness, and the thickness of the material on the fingers is 55%-100% less than the thickness of the material on the palm. The term "vibration-absorbing gloves" means shock-absorbing gloves that meet the standard, while "vibration-absorbing gloves" refer to those gloves that have the function of reducing vibration, regardless of whether they meet the standard.

Summary of the invention

An object of the present invention is to provide a vibration-proof glove with a finger pad that is thicker and softer than the pad at the palm. Thicker and/or softer finger pads are used to compensate for the higher resonant frequencies of the fingers for forced vibration. .

Another object of the present invention is to provide a shock-absorbing glove that reduces the resonance frequency and enhances vibration transmission, so as to provide better protection for the fingers.

Another object of the present invention is to provide a shock-absorbing glove that reduces the resonance frequency of the fingers, so as to protect the nerves, blood vessels, muscles and bones of the hands that use vibration tools for a long time.

A vibration insulation protector, which is a shock-absorbing glove with various thicknesses of padding, used to reduce hand vibration, and includes:

A grasped surface, which is in full or partial contact with the object being grasped; and

A back facing surface, which is set relative to the grasping surface, and is fully or partially in contact with the back of the hand;

The grasped surface also includes a palm surface, which has an elastic material on the palm surface, and the elastic material is compressible under an applied force and has a small overall volume.

Among the various parts of the arm system, the resonance frequency of the shoulder and upper arm is the lowest, and toward the fingertips, the resonance frequency continues to increase. Use vibration damping protective gear to change the vibration transmitted from the hand-held tool to the hand and change the resonance peak on the frequency spectrum. The use of compressible materials with thicker or/and softer properties for shock-absorbing insulating protective gear has a tendency to reduce the resonance frequency.

The shock-absorbing and insulating protective gear provided by the present invention increases the softness and thickness of the area related to the palm and the lower part of the finger, so that the resonance frequency of the finger and the fingertip, the most sensitive part of the arm system, is reduced.

The shock-absorbing and insulating protective gear provided by the present invention covers the fingers, the palm and the back of the hand with the grasping surface and the back surface respectively, and protects the fingers, the palm and the back of the hand. More specifically, the shock-absorbing and insulating protective gear provided by the present invention is a glove with reduced hand vibration.

The word glove should be understood as defined according to the definition in the Macmillan dictionary. That is to say, a piece of fabric used to cover fingers and hands, which also includes mittens (ie a glove in which one part is used for the thumb and the other part is used for the fingers).

According to at least one embodiment of the present invention, the back of the glove is the glove side covering the back of the hand and the back side of the fingers corresponding to the back of the hand, that is, the sun surface of the hand. According to at least one embodiment of the present invention, the grasped surface is the side covering the palm and the side corresponding to the fingers of the palm, that is, the shade of the hand.

According to at least one embodiment of the present invention, the inner surface of the grasped surface is a surface facing the palm and fingers, and the outer surface of the grasped surface is a surface opposite to the inner surface. Therefore, the outer surface may be the surface facing the surrounding and/or the material to be grasped. In addition, the inner surface of the back facing surface of the glove is the surface facing the back of the hand and the fingers, and the outer surface of the back facing surface is the opposite surface of the inner surface. Therefore, the outer surface of the back of the hand faces the surrounding.

According to at least one embodiment of the present invention, the length of the finger covering part corresponds to the length from the boundary between the palm covering part and the finger covering part or folded to the end of the finger covering part.

Each grasped surface and each back facing surface includes an inner surface and an outer surface, and the covering used for shock isolation is mainly subjected to the force from the inner surface, such as pressure. During work, at least one finger can be covered by the covering, and the covering covers the fingers and/or palms partially or completely.

A covering for shock isolation should be understood as any component used to protect hands and/or fingers from damage that may occur when using vibration equipment, such as: but not limited to drills, circular saws, chain saws or other saws , Brush cutter, tamping machine, sander, grinder, impact wrench, pneumatic hammer, rivet gun, valve steering wheel or operating handle, etc.

Fingers refer to several branches at the front of the hand, such as thumb, index finger, middle finger, ring finger and little finger. Each finger is composed of several phalanges connected by joints. According to the distance between each phalange and the heart, the finger part can be divided into: the distal segment of the finger, the middle segment of the finger, and the proximal segment of the finger. The palm is the side of the hand that the fingertips touch when making a fist. In the shock-absorbing and insulating protective gear provided by the present invention, elastic materials are distributed on the fingers and palms, and have different distributions on the fingers and palms. For example, the elastic materials can cover at least 33% of the palm and fingers, or at least 50% of the area. Area or at least 67% of the area.

In another embodiment, the surface of the metacarpal bone covers the fingers and the palm, and the elastic material is arranged to cover the finger area and the palm area. The thickness of the elastic material arranged to cover the finger area is greater than that of the palm area

In another embodiment, elastic materials with different characteristics are also arranged to cover the distal interphalangeal joints, the proximal interphalangeal joints and the metacarpophalangeal joints to reduce the resonance frequency and enhance the protection of the finger's vibration damping protector.

Some materials with compressible properties such as but not limited to foam, air bladder or gel are suitable for the elastic material of the present invention. When subjected to an external force, these materials are compressed and deformed. When the external force disappears, they return to their original shape and characteristics. After being repeatedly or frequently subjected to external forces, the material with foam or air bladder may not be able to return to its original shape and characteristics. This is because the microstructure is subjected to multiple or frequent stresses. Destruction. When this happens, the correct thing is to replace it in time to restore the original appearance of the elastic material. Thicker elastic materials can provide stronger shock absorption and insulation protection for the hands, but they will reduce the grip and cause the loss of finger flexibility. However, thinner elastic materials cannot reduce the resonance frequency, making it difficult to achieve hand shock absorption and insulation protection. Therefore, the thickness of the elastic material should be carefully selected. For the above-mentioned elastic materials, the suitable thickness is: but not limited to 2mm-10mm, specifically: 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm and 10mm .

In the shock-absorbing and insulating protective gear of the present invention, in particular, the thickness of the elastic material distributed on the fingers is generally greater than the thickness of the elastic material distributed on the palm, for example: the average thickness of the elastic material distributed on the fingers is greater than or equal to the thickness distributed on the palm The thickness of the elastic material is 1mm, or 2mm, or 3mm, or thicker. In another embodiment, the maximum thickness of the elastic material distributed on the fingers is greater than or equal to the thickness of the elastic material distributed on the palm of 1 mm, or 2 mm, or more than 3 mm.

In another embodiment, the maximum thickness of the elastic material arranged to cover the finger area is 1 mm, 2 mm or 3 mm thicker than the elastic material arranged to cover the palm area.

Setting different thicknesses of elastic materials at different positions of the fingers can effectively reduce the vibration frequency to protect the fingers. For example, the thickness of the elastic materials distributed on the fingers, palms, and backs of the hands are different, and they decrease in steps from fingertips to palms. the trend of. In another embodiment, in particular, the thickness of the elastic material distributed in the distal segment of the finger is greater than or equal to 1 mm, or 2 mm, or 3 mm or more thicker than the thickness of the elastic material distributed in the middle segment of the finger.

In another embodiment, in particular, the thickness of the elastic material distributed in the middle segment of the finger is greater than or equal to the thickness of the elastic material distributed in the proximal segment of the finger 1 mm, or 2 mm, or 3 mm, or more.

In another embodiment, in particular, the thickness of the elastic material distributed in the proximal segment of the finger is greater than the thickness of the elastic material distributed in the palm of the hand by 1 mm, or 2 mm, or 3 mm, or thicker.

Thick fingers can resist vibration more effectively, and the resonance frequency has a lower impact on these fingers. But in any case, the little finger, ring finger and middle finger are the parts of each finger that need to be protected. Therefore, the shock-absorbing and insulating protective gear of the present invention also has elastic materials distributed on the little finger, ring finger and middle finger, and the vibration resonance frequency is lower. For example, the thickness of the elastic material distributed on the little finger, ring finger and middle finger is larger than that on the index finger and thumb. The thickness of the elastic material is greater than or equal to 1mm, or 2mm, or 3mm, or thicker.

In the shock-absorbing insulating protective gear provided by the present invention, the elastic material can be characterized by a compressive modulus, and can be measured through tests to determine the compressibility of the elastic material and obtain the deformation amount of the elastic material. The compression modulus of the elastic material distributed in the fingers is generally smaller than the compression modulus of the elastic material distributed in the palm. For example, the compression modulus of the elastic material distributed in the fingers is less than the compression modulus of the elastic material distributed in the palm by at least 10%. Or 20%, or 30%.

Set up elastic materials with different compression modulus at different positions of the finger, and are subjected to force during the grasping object and compressed to different degrees to further adjust the thickness of the elastic material at different positions of the finger, and effectively reduce the vibration frequency to protect the finger. For example: distribute elastic materials with different compressive moduli on the fingers, palms and back of the hands. In another embodiment, the compression modulus of the elastic material distributed in the distal segment of the finger is less than or equal to at least 10%, or 20%, or 30% of the compression modulus of the elastic material distributed in the middle segment of the finger.

In another embodiment, the compression modulus of the elastic material distributed in the middle segment of the finger is less than or equal to at least 10%, or 20%, or 30% of the compression modulus of the elastic material distributed in the proximal segment of the finger.

The compression modulus of the elastic material distributed in the palm is less than or equal to the compression modulus of the elastic material distributed in the fingers, especially in the proximal part of the finger and the adjacent palm, which is particularly important for reducing the vibration resonance frequency and protecting the fingers. . In another embodiment, the compression modulus of the elastic material distributed in the proximal segment of the finger is less than or equal to the compression modulus of the elastic material distributed in the palm of at least 10%, or 20%, or 30%.

In the elastic material provided by the present invention, the material used in the high-density material layer is elastomer or high-density thermoplastic rubber (TPR), such as polyvinyl chloride rubber.

Therefore, the shock-absorbing and insulating protective gear of the present invention also has elastic materials distributed on the little finger, ring finger and middle finger. For example, the thickness of the elastic material distributed on the little finger, ring finger and middle finger is greater than or equal to the thickness of the elastic material distributed on the index finger and thumb. 1mm, or 2mm, or 3mm, or thicker.
