Description

Technology Field

[0001] The present invention relates to a glove for the purpose of user protection, and more specifically, to a glove configured such that a composite filler is filled between an outer shell and an inner shell, and protective guards are provided in the parts where each finger is inserted, thereby enabling the user's fingers to be protected, in particular, from strong impacts or sharp objects during work. Background Technology

[0003] Generally, it is advisable for factory workers to wear gloves to protect their hands.

[0004] However, since gloves of a standard configuration cannot completely prevent damage from strong impacts or sharp objects regardless of thickness, finger fractures or amputations may occur even while wearing gloves.

[0005] In addition, there is a risk that the glove may get caught in the rotating shaft of the machine in an instant, and as a result, the worker's hand may be crushed or, in severe cases, lose their life.

[0006] As such, the protective effect of wearing gloves is limited, and on the contrary, serious damage that is difficult to recover from may occur, so there is a significant need for gloves with a configuration that can solve the aforementioned problems.

[0007] And due to this necessity, inventions such as the “finger protection work glove” of Korean Registered Patent Publication No. 10-1814682 and the “finger protection safety glove” of Korean Registered Patent Publication No. 10-1713763 have been proposed and disclosed.

[0008] However, while a certain level of effectiveness can be obtained using the gloves proposed by the aforementioned prior art inventions, they still fail to completely prevent damage caused by strong impacts or sharp objects.

[0009] In particular, there is a significant need for gloves that can provide superior protection, as there is vulnerability to penetration by sharp objects such as rotating blades. Prior art literature

Specific details for implementing the invention

[0027] The present invention relates to gloves for the purpose of user protection, and,

[0028] The device is characterized by comprising: a work glove (100) into which a user’s hand is fitted and a composite filler (101) is filled between the outer shell and the inner shell; and a curved protective device (110) that is fitted between the outer shell and the inner shell of a finger-shaped part (102) into which the user’s fingers are fitted one by one in the work glove (100), thereby protecting the fingers from external impact or sharp objects.

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0031] First, the above-mentioned work gloves (100) are special gloves used for the purpose of protecting the hands of a user working in a factory, etc., and are characterized by having a composite filler (101) filled between an outer layer and an inner layer made of cloth or leather.

[0032] That is, as shown in FIG. 1, a composite filler (101) is filled into all the spaces formed between the outer shell and the inner shell of the work glove (100) so that the user's hand can be protected from external impacts or sharp objects.

[0033] To this end, as shown in FIG. 2, the composite filler (101) is characterized by being composed of a plurality of aramid fibers (101b) manufactured in a yarn shape and mixed in a tangled manner between foam (101a) made of any one of EVA (Ethylene Vinyl Acetate), polyurethane, or polyethylene.

[0034] Therefore, excellent shock absorption and shock dispersion effects are achieved by the physical properties of EVA, polyurethane, or polyethylene, and cut resistance can be significantly enhanced by the physical properties of aramid fiber (101b).

[0035] At this time, since the foam (101a) and aramid fiber (101b) of the above-mentioned material are both lightweight, the problem of the weight increasing significantly due to the filling of the entire interior of the work glove (100) with the composite filler (101) does not occur.

[0036] In addition, the above-mentioned work gloves (100) can be configured such that the thickness in the direction of the back of the hand and fingers from the inner layer to the outer layer is thicker than that of general protective gloves, allowing a larger amount of composite filler (101) to be filled.

[0037] That is, the thickness of the above-mentioned work glove (100) from the inner layer to the outer layer in the direction of the palm and finger soles is formed to be within the same range as the thickness of a general protective glove, but the thickness in the direction of the back of the hand and finger backs is formed to be thicker so that the amount of composite filler (101) can be varied according to direction.

[0038] At this time, based on the thickness in the palm and palm direction, it is preferable that the thickness in the back of the hand and finger direction be formed to be 1.5 to 1.8 times thicker, and with this configuration, the protective effect of defending against external impacts or sharp objects can be significantly improved without affecting the user's wearing comfort or usability.

[0039] Additionally, the work glove (100) may be composed of a connecting part (104) which is a fiber with a pattern woven by arranging nylon and enzyme-treated viscose in an alternating manner, connecting a certain portion of the outer and inner layers that connects the finger-shaped part (102) and the remaining part, the main body part (103).

[0040] At this time, the tensile strength can be reduced by enzymatic treatment in which the viscose is immersed for about 30 to 40 minutes (min) in a state where cellulase with a concentration of 1 weight percent is brought to an activation temperature of 45 to 60°C.

[0041] And the connecting part (104) woven with the above-mentioned pattern can be positioned and connected between the finger-shaped part (102) and the main body part (103) through sewing or heat fusion.

[0042] Accordingly, nylon may be arranged in the width direction of the work glove (100) and enzyme-treated viscose may be arranged in the length direction, and as a result, as shown in FIGS. 3a and 3b, when the work glove (100) is stretched in the length direction with a strength greater than a certain amount, the viscose is cut and the finger-shaped part (102) can be separated from the main body part (103).

[0043] That is, when the tensile force when the above-mentioned work glove (100) gets caught in the rotating shaft of the machine and the tensile force in the opposite direction when the user tries to pull their hand out are applied simultaneously, a cut occurs in the connecting part (104), and it is possible to prevent damage to the user or prevent greater damage from occurring.

[0045] In addition, the above protective device (110) is a means for enhancing cut resistance and is provided in a form inserted between the outer and inner layers of the work gloves (100), serving to protect the user's fingers mainly from sharp objects.

[0046] That is, the above protective device (110) is provided in a form that is inserted between the outer and inner layers of the finger-shaped portion (102) into which the user's fingers are inserted one by one in the work glove (100), so that the cut resistance can be greatly enhanced.

[0047] To this end, the protective device (110) must be configured with a curved shape as a whole to match the shape of each finger-shaped part (102) composed of five parts with different lengths, and at the same time, the area and length must all be different.

[0048] And as illustrated in FIG. 4, all protective gear (110) provided on the work gloves (100) must be provided in a form that can protect each joint of the fingers in the direction of the fingers.

[0049] This is because most amputation accidents during work occur in the direction of fingers, and with this configuration, it is possible to obtain a protective effect that defends against sharp objects, especially rotating blades, without affecting the user's wearing comfort or usability.

[0050] Therefore, the above protective gear (110) must be made of a material specialized for cut resistance, and the increase in weight, which acts as a cause of reduced user comfort, must be minimized.

[0051] That is, as illustrated in FIG. 5, the protective device (110) is characterized by being manufactured using a core-sheath type composite spun yarn formed by spirally winding two or more strands of nylon around a core (111) made of ultrahigh molecular weight polyethylene (UHMWPE) fiber to enhance cut resistance.

[0052] At this time, as the molecular weight of the ultra-high molecular weight polyethylene increases, the strength and durability improve, and in particular, if one composed of a molecular weight of 3,000,000 g / mol or more is used, the cut resistance is enhanced and the material has properties suitable for the use of the present invention, so consequently, it is preferable to use a fiber with a molecular weight of 3,000,000 to 6,000,000 g / mol.

[0053] In addition, as the nylon fiber, it is preferable to use nylon 6, which has an average molecular weight of 20,000 to 30,000 g / mol, a glass transition temperature (Tg) of 40 to 50°C, and a melting point of 210 to 220°C.

[0054] In the case of nylon 6.6, it is stable in high-temperature environments because its glass transition temperature and melting point are higher, but considering that its cut resistance may be reduced, it is preferable to use nylon 6.

[0055] And the core-sheath type composite spun yarn can be manufactured in a form in which the surface of the core (111) is wrapped with a circumferential yarn (112) using a rotating spindle or covering device, and as shown in FIGS. 6a and 6b, it can be manufactured in a more complex twisted form, such as an S twist, Z twist, or composite twist, to further strengthen the bond between the core (111) and the circumferential yarn (112).

[0056] In addition, to further enhance cut resistance, the perimeter yarn (112) may be manufactured in a form that wraps the surface of the core yarn (111) in multiple layers, and a heat treatment process may be performed immediately after the relationship between the core yarn (111) and the perimeter yarn (112) is formed in order to strengthen fixation and stabilize twisting.

[0057] In addition, the surface of the core-sheath composite spun yarn can be coated with silicone resin to provide additional heat resistance, abrasion resistance, and water resistance.

[0058] And the above multiple protective gears (110) can be connected to each other by heat-fusing them using ultra-high molecular weight polyethylene fibers, thereby preventing displacement of the work gloves (100) due to continuous use.

[0059] That is, one or more polyethylene fibers can act as joints between the protective gear (110) and prevent displacement.

[0060] At this time, since ultra-high molecular weight polyethylene fibers have low surface energy and weak adhesion, thermal fusion can be performed after improving hydrophilicity through surface modification using a plasma treatment method.

[0062] The embodiments described above are provided as examples to ensure that the technical concept of the present invention is sufficiently conveyed to those skilled in the art to which the present invention belongs, and the present invention is not limited to the embodiments described above and may be embodied in other forms.

[0063] To clearly explain the present invention, parts unrelated to the explanation have been omitted from the drawings, and in the drawings, the width, length, thickness, etc. of the components may be exaggerated or reduced for convenience.
