Description

Glove structure and method of manufacturing the same TECHNICAL FIELD

[0001] The present invention relates to the field of glove technology, and in particular, to a glove structure and method of manufacturing the same that can enhance the protection of the wearing part. BACKGROUND

[0002] Gloves are a versatile protective equipment widely used in various working and living places to protect hands from injury. In some 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 working gloves are provided with 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 and runs 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, as well as some small muscles on 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, based on the gripping action during work, only the palm is used, and the wrist is not used. Therefore, the injection-molded components are only concentrated on the palm part as mentioned above to increase the palm grip slip resistance or protect the palm.

[0004] Specifically, for example, in US Patent No. US10,271597B2, injection-molded components are designed to improve the gripping ability and flexibility of gloves. The US patent also discloses an injection-molded wrist strap, but the injection-molded wrist strap is mainly designed on the back of the wrist and its total length does not exceed more than 50% of the circumference of the wrist. The main purpose is to help tighten the gloves on the user's hand, and it fails to provide effective protection for the wrist.

[0005] Similarly, Chinese Patent No. CN103415223B also discloses a glove with injection-molded components, which mainly aims to provide grip, flexibility, flexibility, and tactile properties. Although the Chinese patent discloses that part of the injection-molded components is provided on the wrist guard, the main function of the part of the injection-molded components is to prevent the glove from being torn when it is pulled during wearing. The specific setting method of the injection-molded components in the Chinese patent and the proportion of the circumference of the wrist are not clear, and the glove provided by the Chinese patent also fails to provide effective protection for the wrist. At the same time, the Chinese patent is not conducive to the discharge of sweat in the glove, which can cause the glove to easily smell, deteriorate, and shorten the service life of the glove.

[0006] In addition to the above defects, the existing gloves do not have a supporting component at the wrist and even the arm, so there are also problems in use, such as the flat entry of the glove, the small space leading to difficulty in wearing and taking off, and the like. In addition, the existing gloves can only be stacked when stored, and the injection molded component made of elastic material is quite easy to stick to foreign matter, making it difficult to keep the surface of the glove clean. On the other hand, since the gloves are placed flat, the sweat in the gloves cannot be effectively 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 is no working glove with an injection molded component designed specifically for wrist protection, and there are other technical problems as described above, and the structure of the existing gloves needs to be further improved. Technical problem

[0008] In view of the above, one purpose of the present application is to provide a glove structure that can effectively improve the protection of the wearing part and a manufacturing method thereof. Technical solution

[0009] The glove structure of the present application comprises: a glove core shaped with a palm portion, the palm portion being shaped into a sleeve between the bottom end and the first entry of the glove core; an injection molded component having a curved surface shape corresponding to the sleeve, the injection molded component being covered on any part of the outer surface of the sleeve.

[0010] With the above structural features, the glove structure of the present application can provide more comprehensive protection to the inner and outer sides of the wrist by covering the injection molded component on the outer surface of the sleeve of the glove core. In addition, the injection molded component can be protected to the wrist and even the forearm according to the extension length of the sleeve, so that the ulnar nerve of the hand is well supported, 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, which is beneficial to the discharge of sweat in the glove, avoids the glove from easily smelling and deteriorating, and further increases the service life of the glove.

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

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

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

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

[0015] According to the above structural features, the glove structure of the present application can use the three-dimensional curved surface shape of the injection molding assembly after injection molding to support the first entry port of the glove in a circular ring shape in a normal state, so that the first entry port of the glove can be raised to a three-dimensional ring shape when the glove is placed flat without flattening. Compared with the existing soft and flat glove structure, the glove has a larger opening for wearing, which is beneficial for one hand to enter the glove and can extend to 70% to 80% of the inside, thereby greatly reducing the operation of pulling the wrist sleeve of the glove with great force with one hand during the wearing process, maintaining the close-fitting effect of the first entry port of the glove and prolonging the service life of the glove. In addition, for the safety of gloves used in dangerous work, when the first entry port of the glove maintains a three-dimensional ring shape, it is easy and quick to take off the glove in case of danger such as being rolled into a machine. The above-mentioned glove structure can quickly discharge the sweat in the used glove, avoid the glove from easily emitting odor and deteriorating, and further increase the service life of the glove.

[0016] Further, the injection molding assembly of the glove structure of the present application is mainly made of elastic materials such as TPE and TPU, which causes the surface of the injection molding assembly to easily adhere to dust and hair; therefore, the glove structure of the present application can make the glove stand upright as a whole, avoid the glove from adhering to dirt when in contact with objects, and effectively keep the surface of the glove structure clean through the above-mentioned first entry port structure feature which is in a three-dimensional ring shape in a normal state. The above-mentioned glove structure can quickly discharge the sweat in the used glove, avoid the glove from easily emitting odor and deteriorating, and further increase the service life of the glove.

[0017] According to the above structural features, the first entry port of the glove core is provided with an annular elastic member made of heat-shrinkable material or thermoplastic material; and the inner surface of the injection molding assembly is provided with a ribbed portion, which is integrated with the annular elastic member.

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

[0019] According to the above structural features, the first entry port is formed into a tightening sleeve with an inner buckle shape through the combination of the ribbed portion and the annular elastic member.

[0020] According to the above structural features, the second through-hole periphery of the injection molding assembly is expanded to form an elastic portion, and the outside of the elastic portion forms a raised edge on the outer surface of the injection molding assembly, and / or the inside of the elastic portion forms a raised edge on the inner surface of the injection molding assembly.

[0021] With the above structural features, the glove structure of the present application can utilize the structural strength of the annular elastic member in a circular ring shape in a normal state to form a ribbed portion at the first through-hole of the glove structure, so that the first through-hole of the glove can be jointly supported by the annular elastic member and the ribbed portion of the injection molding assembly to form a three-dimensional ring shape when laid flat, and the tightened cuff does not collapse, which is beneficial for quickly putting on or taking off the glove and quickly draining sweat inside the glove, thereby prolonging the service life of the glove.

[0022] Due to the possibility of displacement of the first through-hole of the glove core during mold closing and injection molding, the risk of the thread of the glove core being exposed from the first through-hole, and the possibility of causing the injection molding to end with a glue mark due to the displacement of the first through-hole, affecting the appearance of the product. Therefore, by using the above structural features, the glove structure of the present application forms the elastic portion to prevent the thread of the glove core from being exposed and ensure the appearance of the glove structure.

[0023] With the above structural features, the glove structure of the present application forms an integrated tightening cuff with a narrowing function on the inner surface of the glove core by combining the ribbed portion with the annular elastic member, which can solve the problem of cuff deformation of existing glove products, and avoid the problem of inconsistent and uncoordinated appearance of the cuff shrinkage structure affecting the appearance of the glove.

[0024] With the above structural features, the glove structure of the present application forms a tightening cuff with an inner buckle shape at the first through-hole by combining the ribbed portion with the annular elastic member, which can ensure a good fit with the hand and prevent the glove from easily slipping off during use.

[0025] With the above structural features, the glove structure of the present application forms a tightening cuff with an inner buckle shape at the first through-hole by combining the ribbed portion with the annular elastic member, which conforms to the ergonomics, so that the glove of the present application can match the shape of the human forearm, which becomes thick from the palm end to the elbow end and then narrows near the elbow end, regardless of the length of the sleeve of the glove core, so that the tightening cuff can be stably buckled on the arm at each position between the palm and the elbow.

[0026] With the above structural features, the glove structure of the present application forms a tightening cuff with an inner buckle shape at the first through-hole by combining the ribbed portion with the annular elastic member, which can ensure a good fit with the human hand and prevent liquid from leaking into the glove from the glove cuff during work.
