Description
Technical Field
The invention relates to a labor protection material, in particular to a personal protection device which can effectively reduce the elastic modulus, reduce vibration and improve the protection effect.
Background
The use of hand held vibrating tools is very common and prolonged use can cause serious injuries such as: syndrome of arm vibration. 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 different. Resonances at different parts of the hand-arm system are considered to have a continuous correlation with injury.
In many countries around the world, more than 10% of workers are using vibration tools for more than 2 hours per day. This damage does not occur immediately, but over time, vibrations will cause severe damage to the hands nerves, blood vessels, muscles and bones. This damage is called Arm Vibration Syndrome (Hand Arm Vibration Syndrome).
The vibration isolation function of the flexible compressible gasket, such as: the thickness is increased, the softness and the mechanical loss factor are improved, so that the vibration glove can protect hands. Thicker, softer materials can increase the isolation properties and reduce the natural resonant frequency of the tool/glove/hand system.
A particular problem is that the fingers are lightweight compared to the palm, so that the vibration frequency of the fingers is higher than in the palm area, which increases the risk of injury. The vibration frequency is proportional to the square root of the stiffness of the material and inversely proportional to the weight of the material, as shown by the equation omegan＝(k/m)1/2As shown. Wherein, ω isnThe angular velocity (radian per second), the stiffness (N/m) of the material, and the mass (kg) of the material are indicated by k and m, respectively.
The efficiency of the isolation is judged by a Transmission factor (T), which is the ratio of the acceleration of the hand inside the glove to the tool acceleration. T greater than 1 indicates an amplification of the acceleration (T equal to no effect), T less than 1 indicates a retardation of the acceleration (regeneration).
The protective action of the glove depends on a number of external factors, not on frequency, such as: push (feed) force, grip strength, individual differences (e.g., mass and stiffness of the operator's hand, and the operator's anatomy), tool type, and working conditions, among others.
Taking the anatomical aspect of the fingers as an example, different sizes and weights of palm and fingers will cause different parts of the hand to generate different natural resonant frequencies in the tool/glove/hand system. Especially slimmer fingers (e.g., little and ring fingers) and finger portions near the fingertips typically produce higher resonant frequencies and are therefore more difficult to protect.

The Chinese patent application 201110219663.9 discloses a pair of gloves for reducing vibration, each glove comprises a glove body, each glove body comprises 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 thickened pad a is positioned on the palm part and close to the finger part, the thickened pad b is positioned on the palm part and close to the thumb part, the thickened pad c is positioned on the palm part and close to the lower side of the thumb part, the wrist part is composed of a lap and a nylon fastener tape, the thickened pad a is a breathable layer, the thickened pad b is an anti-skid wear-resistant anti-vibration layer, and the thickened pad c is an anti-vibration wear-resistant layer. Under the condition of strong shock, the hand joint can be effectively protected or the damage degree can be reduced when an accident happens, the hand joint of a user is well protected, the structure is reasonable, the wearing is comfortable, the effect is obvious, and the hand joint protection device is suitable for work or entertainment activities of strong shock.
When the hand is exposed to a forced vibration, different parts of the arm system will be subject to resonance. Such as: the upper arm has a resonant frequency of about 10Hz, the palm and wrist have a frequency of about 20Hz to 30Hz, and the fingers have a resonant frequency of about 100Hz to 300 Hz. It is well known that the most damage to tissue from forces is at the resonant frequency. The resonance frequency is higher at the tip of the finger compared to the middle part of the finger, which is subjected to a higher resonance frequency than at the base of the finger. Longer or thinner fingers have higher resonant frequencies than shorter and thicker fingers.
The resonant frequency of the arm system also varies with grip strength, and generally, a larger grip will increase the resonant frequency. The transmission of forced vibration acceleration is strongly related to resonance, reaching a maximum at the resonance frequency and decreasing with increasing frequency.
EN/ISO 10819: 2013 is an international standard for normative anti-seismic gloves, in which only Vibration Transmission (Vibration Transmission) on the palm is measured. The standards further point out that the anti-shock material must remain uniform in properties and thickness, with the material thickness on the fingers being 55% to 100% less than the material thickness on the palm. The term "vibration damping glove" means a standard vibration damping glove, and the term "vibration damping glove" means a glove having a vibration damping function regardless of whether the standard is satisfied or not.
Disclosure of Invention
It is an object of the present invention to provide a vibration-proof glove with finger pads that are thicker and more flexible than the pads at the palm. Thicker and/or softer finger pads are used to compensate for the higher resonant frequency of the finger to the forced vibration. .
Another object of the present invention is to provide a pair of vibration damping gloves, which can reduce the resonance frequency and enhance the vibration transmission, thereby providing better protection for the fingers.
It is yet another object of the present invention to provide a vibration damping glove that reduces the resonance frequency of the fingers to provide protection to nerves, blood vessels, muscles and bones on the hand that are used with a vibration tool for a long period of time.
A damping insulation protector (damping insulation protector) is a damping glove with padding materials of various thicknesses, which is used for reducing the vibration of hands and comprises:
a grasping face which is in full or partial contact with the grasped object; and
a back-facing surface, which is arranged opposite to the gripping surface and is wholly or partially in contact with the back of the hand;
the grabbing surface also comprises a palm surface, and the elastic material is arranged on the palm surface, has compressibility under the action of acting force and has small integral volume.
The resonance frequency of the shoulder and the upper arm is the lowest among the various parts of the arm system, and the resonance frequency increases toward the fingertips. Vibration reduction braces are used to alter the vibration transmitted by the hand tool to the hand and to alter the formants in the frequency spectrum. The use of compressible materials with thicker or/and softer properties for shock absorbing insulating braces has a tendency to lower the resonant frequency.
The shock-absorbing insulating protector provided by the invention has the advantages that the flexibility and the thickness are increased through the areas related to the lower parts of the palm and the fingers, so that the resonance frequency of the most sensitive parts, namely the fingers and the fingertips, in an arm system is reduced.
According to the shock-absorbing insulating protective clothing provided by the invention, the grabbing surface and the back surface are respectively covered on the finger, the palm and the back of the hand, so that the finger, the palm and the back of the hand are protected. More specifically, the invention provides a shock-absorbing insulating protector which is a glove capable of reducing hand vibration.
The term glove should be understood as being defined according to the definitions in the Macmillan dictionary. That is, a piece of fabric intended to cover the fingers and hand, which also includes a mitt (i.e., a glove in which one portion is used for the thumb and the other portion is used for the fingers).
According to at least one embodiment of the invention, the side of the glove facing away from the hand is the side of the glove covering the back of the hand and the side of the back of the fingers corresponding to the back of the hand, i.e. the male side of the hand. According to at least one embodiment of the invention, the side to be grasped is the side covering the palm and the side corresponding to the fingers of the palm, i.e. the female side of the hand.
According to at least one embodiment of the invention, the inner surface of the grasped side is the palm and finger facing surface and the outer surface of the grasped side is the surface opposite the inner surface. Thus, the outer surface may be the surface facing the surroundings and/or the material to be gripped. Additionally, the inner surface of the opposing face of the glove is the surface facing the back of the hand and fingers, while the outer surface of the opposing face is the opposite surface of the inner surface. Thus, the outer surface of the back of the hand faces the surroundings.
According to at least one embodiment of the present invention, the length of the finger covering portion corresponds to a length from a boundary or a fold between the palm covering portion and the finger covering portion to an end of the finger covering portion.
Each of the grabbed faces and each of the oppositely facing faces include an inner surface and an outer surface, and the cover for seismic isolation is primarily subjected to forces from the inner surface, such as: and (4) pressure. In operation, at least one finger can be covered by a covering that provides partial or full coverage of the finger and/or palm.
A cover for vibration isolation is to be understood as any means for protecting the hand and/or fingers from damage that may occur when using vibrating instruments such as: but are not limited to, drills, circular saws, chainsaws or other saws, brushcutters, tampers, sanders, grinders, impact wrenches, pneumatic hammers, rivet guns, valve-steering wheels or operating handles, and the like.
The finger refers to a plurality of branches at the front end of the hand, such as: thumb, index finger, middle finger, ring finger, little finger, etc. Each finger is formed by connecting a plurality of phalanges through joints, and the finger parts can be divided into the following parts according to the distance between each phalange and the heart: a telecentric segment of the finger, a mid-segment of the finger, and a proximal segment of the finger. The palm is the side of the hand that the fingertips touch when making a fist. The shock-absorbing insulating protective clothing provided by the invention has the advantages that the elastic materials are distributed on the fingers and the palm, and have different distributions on the fingers and the palm, such as: the elastic material covers at least 33% of the area of the palm and fingers, or at least 50% of the area or at least 67% of the area.
In another embodiment, the metacarpal surface covers the fingers and 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 the thickness of the palm area
In another embodiment, elastomeric materials having different characteristics are also arranged to cover the distal interphalangeal joint, the proximal interphalangeal joint and the metacarpophalangeal joint to reduce the resonance frequency and enhance the protection of the shock absorbing protector for the fingers.
Some materials with compressible properties such as: but not limited to foam structures (foam), bubble structures (airbedder) or gels (gel) are suitable for the elastic material of the present invention. When the material is subjected to external force, the material is compressed to deform, and when the external force disappears, the material restores to the original shape and characteristics. Materials having a foam structure (foam) or air bubble structure (air loader) may not achieve recovery to their original shape and characteristics after multiple or frequent external forces due to the destruction of the microstructure therein after multiple or frequent forces. When the situation happens, the elastic material is correctly replaced in time, so that the original appearance of the elastic material is restored. Thicker elastomeric materials, while providing greater shock absorbing insulation to the hands, reduce grip and result in loss of finger dexterity. And the thinner elastic material can not reduce the resonance frequency, so that the hand damping insulation protection is difficult to realize. Therefore, the thickness of the elastic material should be carefully selected, suitable thicknesses for the above mentioned elastic materials such as: but not limited to 2 mm-10 mm, specifically: 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm and 10 mm.
In the shock absorbing insulating protector of the present invention, in particular, the thickness of the elastic material distributed to the fingers is generally greater than the thickness of the elastic material distributed to the palm, such as: the average 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 by 1mm, or 2mm, or 3mm, or more. In another embodiment, the maximum thickness of the elastic material distributed over the fingers is greater than or equal to 1mm, or 2mm, or 3mm greater than the thickness of the elastic material distributed over the palm.
In another embodiment the maximum thickness of the elastic material arranged to cover the finger area is 1mm, 2mm or 3mm thicker than the elastic material arranged to cover the palm area.
The elastic materials with different thicknesses are arranged at different positions of the finger, so that the vibration frequency can be effectively reduced to protect the finger, for example: the thicknesses of the elastic materials distributed on the fingers, the palms, the backs of the hands and the like are different, and the trend that the thicknesses of the elastic materials are gradually decreased from the fingertips to the palms is in a step shape. In another embodiment, the thickness of the elastomeric material disposed in the distal portion of the finger is greater than or equal to 1mm, or 2mm, or 3mm or greater than the thickness of the elastomeric material disposed in the middle portion of the finger.
In another embodiment, in particular, the thickness of the elastic material distributed in the middle section of the finger is greater than or equal to the thickness of the elastic material distributed in the proximal section of the finger by 1mm, or 2mm, or 3mm, or more.
In another embodiment, in particular, the thickness of the elastic material distributed over the proximal segment of the finger is greater than 1mm, or 2mm, or 3mm, or more, than the thickness of the elastic material distributed over the palm.
The robust fingers can resist the vibration more effectively, and the influence of the resonance frequency on the fingers is lower. However, in any case, the little finger, the ring finger, and the middle finger are portions of the respective fingers that need to be protected strongly. Therefore, the shock-absorbing insulating protector of the invention also distributes elastic materials at the small finger, the ring finger and the middle finger, and the vibration resonance frequency is lower, such as: the thickness of the elastic material distributed in the little finger, ring finger and middle finger is greater than or equal to 1mm, or 2mm, or 3mm, or thicker than the thickness of the elastic material distributed in the index finger and thumb.
According to the damping insulation protector provided by the invention, the elastic material can be characterized by the compression modulus, and can be measured through tests so as to judge the compressibility of the elastic material and obtain the deformation of the elastic material. The compression modulus of the elastic material distributed in the fingers is generally lower than that of the elastic material distributed in the palm, such as: the elastic material disposed on the finger has a compressive modulus that is at least 10%, or 20%, or 30% less than the compressive modulus of the elastic material disposed on the palm.
Set up the elastic material that compression modulus is different at the different positions of finger, receive the effort in snatching the object, by the compression of different degree to further adjust the elastic material's of the different positions of finger thickness, and effectively reduce vibration frequency and protect the finger, for example: elastic materials with different compression moduli are distributed on fingers, palms, backs of hands and the like. In another embodiment, the elastic material disposed in the distal finger section has a compressive modulus at least 10%, or 20%, or 30% less than or equal to the compressive modulus of the elastic material disposed in the middle finger section.
In another embodiment, the elastic material disposed in the medial portion of the finger has a compressive modulus at least 10%, or 20%, or 30% less than or equal to the compressive modulus of the elastic material disposed in the proximal portion of the finger.
The compression modulus of the elastic material distributed on the palm is smaller than or equal to that of the elastic material distributed on the fingers, especially in the proximal section and the adjacent palm part of the fingers, and is particularly important for reducing the vibration resonance frequency and providing protection for the fingers. In another embodiment, the elastic material disposed in the proximal segment of the finger has a compressive modulus at least 10%, or 20%, or 30% less than or equal to the compressive modulus of the elastic material disposed in the palm.
The invention provides an elastic material, wherein the high-density material layer is made of elastomer or high-density thermoplastic rubber (TPR), such as: polyvinyl chloride rubber.
The technical scheme of the invention has the following beneficial effects:
the shock absorbing insulating brace provided by the present invention has a tendency to lower the resonant frequency by using a compressible material with thicker or/and softer properties for the shock absorbing insulating brace, so that the resonant frequency of the most sensitive parts in the arm system, namely the fingers, phalanges and fingertips, is reduced.
The invention provides a shock-absorbing insulating protective tool, which is characterized in that elastic materials with different thicknesses and elastic moduli are arranged on each phalanx and palm of a finger, and the shock-absorbing insulating protective tool can be worn on a hand as a glove, can change the vibration transmitted to the hand by a handheld tool, and can change the resonance peak on a frequency spectrum to reduce the resonance frequency of the hand.

Detailed Description
The technical scheme of the invention is described in detail in the following with reference to the accompanying drawings. Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
Fig. 1 is a schematic view of the construction of one embodiment of the shock absorbing insulating brace of the present invention, as shown in fig. 1, with the gripping side 14 (i.e., the female side of the hand, the side where the grip is performed) and the opposing side (i.e., the male side of the hand, the dorsal side of the hand), each side including an inner surface and an outer surface. The sunny side of the hand is understood to be the side of the hand that is directly exposed to sunlight, while the opposite side of the hand that is not directly exposed to sunlight is the cloudy side of the hand. Grasped side 14 includes palm covering portion 10 and at least one finger covering portion 12, 12'. In fig. 1, the vibration damping glove 1 includes two finger covering portions 12, 12'. The damping insulation protective clothing of this embodiment is gloves, and the face that its snatched and the face that faces dorsad cover respectively on finger, palm and the back of the hand, play the guard action to finger, palm and back of the hand. Each of the grabbed faces and each of the oppositely facing faces include an inner surface and an outer surface, and the cover for seismic isolation is primarily subjected to forces from the inner surface, such as: and (4) pressure. In operation, at least one finger can be covered by a covering that provides partial or full coverage of the finger and/or palm.
Fig. 2 is a schematic view of the structure of an embodiment of the distribution of the shock absorbing insulating protector of the present invention in which the elastic material, as shown in fig. 2, is used for vibration isolation, and the covering for vibration isolation is understood to be any member for protecting the hand and/or fingers from damage that may occur when using a vibration device, and has a thickness of 2mm to 10 mm. In this embodiment, the covering is a first elastic material 31 and a second elastic material 21. The first elastic material 31 is distributed over the palm and can cover at least 33% of the area of the palm and fingers, or at least 50% of the area of the palm or at least 67% of the area of the palm. The second elastic material is distributed on the finger. At least 33% of the area of the palm and fingers, or at least 50% of the area or at least 67% of the area of the fingers can be covered. The thickness of the elastic material distributed on the fingers is generally greater than that distributed on the palm, such as: the average 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 by 1mm, or 2mm, or 3 mm. Alternatively, the maximum thickness of the elastic material distributed over the fingers is 1mm, or 2mm, or 3mm thicker than the elastic material distributed over the palm.
Fig. 3 is a schematic structural diagram of an embodiment of elastic material distribution in the shock-absorbing insulating protector of the present invention, as shown in fig. 3, the first elastic material 31 is distributed at the edge of the palm, and the first elastic material 31 is not used in the center of the palm. A second elastic material 21, a third elastic material 22 and a fourth elastic material 23 are arranged at different phalanges of the finger, respectively. A second elastomeric material 21 is distributed at the proximal phalanx of the finger, a third elastomeric material 22 is distributed at the middle phalanx of the finger, and a fourth elastomeric material 23 is distributed at the distal phalanx of the finger. Robust fingers are more effective against shocks, and the resonance frequency of the shocks on these fingers is lower. However, in any case, the little finger, the ring finger, and the middle finger are portions of the respective fingers that need to be protected strongly. Therefore, the damping insulation protector of the invention also distributes elastic materials at the positions of the little finger, the ring finger and the middle finger, such as: the thickness of the elastic material distributed on the little finger, the ring finger and the middle finger is more than or equal to the thickness of the elastic material distributed on the index finger and the thumb, and the thickness is 1mm, or 2mm, or 3mm, or thicker.
In this embodiment, the thickness of the fourth elastic material 23 distributed on the distal section of the finger is greater than or equal to the thickness of the third elastic material 22 distributed on the middle section of the finger by 1mm, or 2mm, or 3mm, or more, the thickness of the third elastic material 22 distributed on the middle section of the finger is greater than or equal to the thickness of the second elastic material 21 distributed on the proximal section of the finger by 1mm, or 2mm, or 3mm, or more, and the thickness of the second elastic material 21 distributed on the proximal section of the finger is greater than the thickness of the first material distributed on the palm by 1mm, or 2mm, or 3mm, or more, so as to form a stepwise decreasing elastic material distribution form from the fingertip to the palm.
As shown in fig. 3, the second elastic material 21, the third elastic material 22 and the fourth elastic material 23 are distributed mainly on the grasping face 14 at the little finger, the ring finger and the middle finger.
The elastic material can be characterized by a compressive modulus, in this embodiment, the compressive modulus of the elastic material distributed in the fingers is generally smaller than that of the elastic material distributed in the palm, specifically, the compressive modulus of the elastic material distributed in the fingers is at least 10%, or 20%, or 30% smaller than that of the elastic material distributed in the palm.
In fig. 3, the second elastic material 21, the third elastic material 22 and the fourth elastic material 23 distributed at the little, ring and middle finger positions also have different compression moduli. Such as: the compressive modulus of the fourth elastic material 23 distributed at the position of the distal section of the finger is at least 10%, or 20%, or 30% less than or equal to the compressive modulus of the elastic material distributed at the position of the middle section of the finger; the following steps are repeated: the compression modulus of the elastic material distributed at the middle section position of the finger is at least 10 percent, or 20 percent, or 30 percent less than or equal to the compression modulus of the elastic material distributed at the proximal section position of the finger; for another example: the modulus of compression of the elastic material distributed in the proximal segment of the finger is at least 10%, or 20%, or 30% less than or equal to the modulus of compression of the elastic material distributed in the palm.
Elastic materials with different thicknesses and elastic moduli are arranged on each phalanx and palm of the finger and are worn on the hand as the glove, so that the vibration transmitted to the hand by the hand-held tool can be changed, the resonance spectrum transmitted to different parts by the glove is changed, and the resonance frequency of the hand is reduced. The use of compressible materials with thicker or/and softer properties for the shock absorbing insulating brace has a tendency to lower the resonant frequency so that the resonant frequency of the most sensitive parts of the arm system, fingers and fingertips, is reduced.
Figure 4 shows the results of an angle grinder (anglegringer) testing three types of shock transmission on the glove fingers, with glove protector thicknesses set at 2.5mm, 4mm and 8mm, respectively, each curve reflecting the vibration transmission versus frequency at 1/3 octaves. As the finger thickness increases, the transmission peak shifts from a high value of frequency to a low value of frequency, the lower the frequency the better the finger protection.
