Description

Technical Field

[0001] The present invention relates to the technical field of gloves, and in particular to a glove structure capable of improving the protective effect of a wearing part and a manufacturing method thereof. Background Art

[0002] Gloves are a multifunctional protective device that is widely used in various workplaces and living places to protect hands from injury. In certain high-risk working environments, such as construction, machinery manufacturing and laboratories, the use of gloves can greatly improve the safety of workers. In particular, some work gloves have injection-molded components on the palm part (i.e., the partial surface of the fingers and palm) to provide additional protection.

[0003] It is worth noting that the ulnar nerve in the wrist area extends from the brachial plexus in the shoulder, along the lower arm to the end of the little finger. The ulnar nerve is responsible for the sensation of the little finger and the outer half of the ring finger, and is also responsible for the movement of some small muscles in the hand and forearm. Therefore, the protection of the wrist and ulnar nerve is particularly important. However, although the application of injection molded components in gloves has been widely studied and practiced, since the gripping action during work only uses the palm and does not require the use of the wrist, the injection molded components are only concentrated in the palm area as mentioned above, to increase the anti-slip grip of the palm or protect the palm.

[0004] Specifically, for example, in U.S. Patent Publication No. US10,271597B2, the injection molding component is designed to improve the gripping ability and flexibility of the gloves. The U.S. patent also discloses an injection molding wrist strap, but the injection molding wrist strap is mainly designed on the back of the wrist and its total covering length does not exceed 50% of the wrist circumference. Its main purpose is to help fasten the gloves to the user's hand, and it fails to provide effective protection for the wrist.

[0005] Similarly, Chinese Patent Publication No. CN103415223B also discloses a glove with an injection-molded component, the main purpose of which is to provide grip, flexibility, dexterity and tactile properties. Although the Chinese patent discloses that part of the injection-molded component is arranged at the wrist guard, the main function of the injection-molded component is to prevent the gloves from being torn due to pulling the entrance when the gloves are worn, and the specific arrangement of the injection-molded component in the Chinese patent and the proportion of the wrist circumference occupied are not clear, and the gloves provided by the Chinese patent also fail to provide effective protection for the wrist. At the same time, the Chinese patent is not conducive to the discharge of sweat in the gloves, causing the gloves to stink easily, deteriorate and shorten the service life of the gloves.

[0006] In addition to the above defects, the existing gloves have no support components at the wrist or even the arm, so there are also problems such as the gloves are flat and collapsed at the entrance, small space, and difficult to wear and take off. In addition, the existing gloves can only be stored flat and stacked, causing the injection molding components made of elastic materials to be easily sticky to foreign objects, making it difficult to keep the surface of the gloves clean. On the other hand, since the gloves are laid flat, the sweat in the gloves cannot be effectively quickly discharged and evaporated, which easily causes the gloves to smell and deteriorate, and even greatly shortens the service life of the gloves.

[0007] In summary, there are currently no work gloves with injection molded components designed specifically for wrist protection, and there are other technical problems as mentioned above. The existing glove structure needs to be further improved. Summary of the invention

[0008] In view of the above situation, one of the objectives of the present invention is to provide a glove structure and a manufacturing method thereof that can effectively enhance the protective effect of the wearing part.

[0009] The glove structure of the present invention comprises: a glove core formed with a palm portion, wherein the area between the bottom end of the palm portion and a first insertion opening of the glove core is formed into a sleeve; and an injection molding component having a curved surface shape corresponding to the sleeve, wherein the injection molding component is covered on any part of the outer surface of the sleeve.

[0010] By utilizing the above structural features, the glove structure of the present invention can provide more comprehensive protection for the inner and outer sides of the wrist by covering the injection molding component on the outer surface of the glove core sleeve; in addition, the injection molding component can protect the wrist and even the forearm according to the extended length of the sleeve, so that the ulnar nerve of the hand can be well supported, thereby providing more comprehensive protection for the user's hand, enhancing the gripping ability of the glove and improving the safety of the hand. At the same time, the above glove structure increases the air permeability of the glove, facilitates the discharge of sweat in the glove, prevents the glove from stinking and deteriorating, and can further increase the service life of the glove.

[0011] According to the above structural features, the total covering length of the injection molding component is greater than 50% of the circumference of the sleeve.

[0012] According to the above structural features, the injection molding component is continuously covered on the sleeve of the glove core, and the total covering length of the injection molding component continuously covered is greater than 50% of the circumference of the sleeve.

[0013] According to the above structural features, the injection molding component is discontinuously covered on the sleeve of the glove core, and the total covering length of the discontinuous covering of the injection molding component is greater than 50% of the circumference of the sleeve.

[0014] According to the above structural features, the total covering length of the injection molding component is greater than 50% of the circumference of the sleeve and less than or equal to 100% of the circumference of the sleeve.

[0015] By utilizing the above structural features, the glove structure of the present invention can make the total covering length of the injection molding component greater than 50% of the circumference of the sleeve, and can utilize the three-dimensional curved surface shape after the injection molding of the injection molding component to support the first penetration port of the glove in a circular ring shape under normal conditions, so that the first penetration port of the glove when it is laid flat can be supported by the three-dimensional curved surface shape of the injection molding component to present a three-dimensional ring shape without collapsing; compared with the existing soft and flat glove structure, it has a larger insertion opening, which is conducive to one-handed insertion of the glove and can be inserted into 70% to 80% of the inside, thereby greatly reducing the operation of one hand inserting the glove and the other hand having to pull the glove wrist cuff vigorously during the wearing process, maintaining the tight effect of the first penetration port of the glove and also extending the service life of the glove. In addition, for the safety of gloves used in dangerous work, when the first penetration port of the glove is maintained in a three-dimensional ring shape, it can be conducive to easily and quickly taking off the glove when dangers such as being involved in a machine occur. The above glove structure can allow the sweat in the used gloves to be discharged quickly, avoid the gloves from stinking and deteriorating easily, and can further increase the service life of the gloves.

[0016] Furthermore, the injection molding components of the glove structure of the present invention are mainly made of elastic materials such as TPE, TPU, etc., which makes it easy for dust and hair to adhere to the surface of the injection molding components; therefore, the glove structure of the present invention can make the gloves of the present invention stand upright as a whole through the aforementioned first penetration port structure feature that is in a three-dimensional ring shape under normal conditions, so as to avoid the gloves from contacting objects and sticking to them, and effectively keep the surface of the glove structure of the present invention clean. The above-mentioned glove structure can quickly discharge the sweat in the used gloves, prevent the gloves from stinking and deteriorating, and can further increase the service life of the gloves.

[0017] According to the above structural features, an annular elastic member made of heat shrinkable material or thermoplastic material is provided around the first insertion opening of the glove core; an embedded rib is provided on the inner surface of the injection molding component, and the embedded rib is integrated with the annular elastic member.

[0018] According to the above structural features, the annular elastic member is a rubber band or an elastic yarn; and the embedded rib portion is convexly or concavely arranged on the inner surface of the injection molding component.

[0019] According to the above structural features, the first insertion opening is formed into a tightening cuff with an inward buckled shape by combining the ribbed portion with the annular elastic member.

[0020] According to the above structural features, the periphery of the second penetration port of the injection molding component expands to form an elastic portion, the outer portion of the elastic portion forms a raised edge on the outer surface of the injection molding component and / or the inner portion of the elastic portion forms a raised edge on the inner surface of the injection molding component.

[0021] By utilizing the above structural features, the glove structure of the present invention forms a ribbed portion at the first insertion opening of the glove structure, and can utilize the structural strength of the annular elastic member in a normal state in a circular ring shape, so that the first insertion opening of the glove can be supported by the annular elastic member and the ribbed portion of the injection molding component together to present a three-dimensional ring-shaped tightening cuff when laid flat, which is conducive to quickly putting on or taking off the gloves and quickly discharging sweat in the gloves, thereby extending the service life of the gloves.

[0022] Since the first penetration port may be displaced during the mold closing and injection molding process of the glove core, there is a risk that the thread ends of the glove core may be exposed from the first penetration port, and the end of the injection molding may be displaced by the first penetration port, resulting in welding marks on the product, affecting the appearance of the product. Therefore, by utilizing the above structural features, the glove structure of the present invention forms the elastic part to prevent the thread ends of the glove core from being exposed and ensure the appearance of the glove structure.

[0023] By utilizing the above structural features, the glove structure of the present invention is combined with the annular elastic member through the ribbed portion to form an integrated tightening cuff located on the inner surface of the glove core and having a tightening function, which can solve the shrinkage and deformation problem of the cuff of existing glove products and avoid the problem that the appearance of the cuff shrinkage structure is inconsistent and uncoordinated, thereby affecting the appearance of the gloves.

[0024] By utilizing the above structural features, the glove structure of the present invention combines the ribbed portion with the annular elastic member so that the first insertion opening forms a tightened cuff with an inward buckled shape, which can fit the hand well and prevent the glove from slipping off during use.

[0025] By utilizing the above structural features, the glove structure of the present invention combines the ribbed portion with the annular elastic member to form a tightening cuff with an inwardly buckled shape at the first penetration opening, which is ergonomic, so that the glove of the present invention, regardless of the sleeve length of the glove core, can match the shape of the human forearm that first becomes thicker from the palm end toward the elbow end and then shrinks and becomes thinner near the elbow end, so that the tightening cuff can be stably buckled on the arm at various parts between the palm and the elbow.

[0026] By utilizing the above structural features, the glove structure of the present invention combines the ribbed portion with the annular elastic member so that the first insertion opening forms a tightened cuff with an inward buckled shape, which can surely fit the human hand and prevent liquids contacted during work from leaking from the glove cuff into the interior of the glove.
