Abstract

Disclosed is a base material for preparing a finger protection structure, including a main body and abutment blocks. Four corners of each abutment block form four corner cut portions, two corner cut portions of two adjacent abutment blocks together form two first gaps, and areas of the main body exposed to the first gaps are defined as elastic deformation areas. A finger protection structure is cut out of the main body along two elastic deformation areas and one second gap. The finger protection structure includes a base plate and the abutment blocks. Areas of the base plate exposed to the first gaps are defined as elastic deformation areas. When a stressed surface is impacted by a frontal impact force, the abutment blocks abut against each other and the base plate straightens. When the stressed surface is impacted by a lateral rotation force, the elastic deformation areas are elastically deformed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of U.S. patent application Ser. No. 15/955,413, filed on Apr. 17, 2018, which claims the priority benefit of Chinese patent application No. 201820411318.2, filed on Mar. 26, 2018. All of the above-referenced applications are incorporated by reference herein.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a base material for preparing a finger protection structure and a finger protection structure for a protection hand glove.

2. The Prior Arts

Different types of hand gloves provide different functions and features due to their application in different fields. For instance, a protection hand glove worn by a goal keeper in a football match is relatively thick in order to buffer and absorb a frontal impact force of a coming ball, thereby minimizing the injuries caused to the hands of the goal keeper.
A conventional hand glove for sports generally includes a finger portion and a palm portion having an end connected to the finger portion and the other end defining an access into the hand glove such that once inserted into the hand glove, the fingers are received in the finger portion while the palm of the hand is received in the palm portion. Generally, an anti-slip layer is provided on the palm side of the conventional hand glove while soft and/or flexible structures are provided interior thereof so that the wearer can have a certain extent of flexibility and buffering effects.
However, some manufacturers have developed a protection hand glove for football players, especially for goal keepers, wherein some finger protection devices are inserted into the finger portions of the protection hand glove in order to prevent the stress and/or impact force of a catching ball, thereby minimizing the injuries caused to the goal keeper. To be more specific, the finger protection devices are in form of elongated strips fabricated from substantially hard materials, and provide a certain extent of protection to the fingers, but somehow hinder the moving flexibility of the fingers. Therefore, presently most of the protection hand gloves are directed in the field of inward bending activity so as to provide protection of the fingers. It is noted that the improvement lacks in the outward bending activity of fingers.
In addition, the above-stated the finger protection devices are in form of inter-actively connected strips, though lowers and/or the moving flexibility of fingers, are inserted into the protection hand glove and hence can cooperatively absorb and buffer the impact force of a catching ball. The only drawback is that the finger protection strips within the protection hand glove cannot be bent outward such that the finger protection strips are intended to buffer and absorb the frontal impact force of the catching ball. In the event during catching of a coming ball, the finger protection strips may be twisted and/or laterally bent relative to one another when the lateral rotation force of the ball is relatively strong, thereby causing disengagement among the finger protection strips and simultaneously may injure the fingers of the hand glove wearer.
US 20020184696 A1 discloses a reinforcing strip for a goalkeeper's glove. As shown in FIG. 1 of US 20020184696 A1, since the four corners of each of the link member 3 are formed with right angles, and the carrier band 1 has been completely covered by the link members 3, so that the reinforcing strip has an excellent effect of absorbing the frontal impact force.
Although the reinforcing strip can absorb lateral rotation force by twisting and/or laterally bending, its effect is quite limited. When the user wears the goalkeeper's glove of US 20020184696 A1 on his hand to catch ball, once the lateral rotation force of the ball is too large and exceeds the bearable range of the reinforcing strip, most of the lateral rotation force is borne by the user's fingers, resulting the user's fingers to flip laterally and be sprained.
According to lines 3 to 4 of paragraph [0028] of the specification of US 20020184696 A1, link members 3 all of which are glued to the carrier band 1 with a glue layer 4.
However, the twisting and/or lateral bending of the reinforcing strip easily cause the four corners of the link members 3 to be degummed from the carrier band 1. Under long-term use, the degumming degree of the link members 3 becomes more and more serious, which will eventually cause the link members 3 to detach or peel off from the carrier band 1. Once the link members 3 are detached or peeled off from the carrier band 1, the function of the reinforcing strips will be completely lost.
US 20030150136 A1 discloses a unidirectional support device 10. According to in FIGS. 2A to 2E and lines 8 to 10 of paragraphs [0032] of the specification of US 20030150136 A1, an aperture 20 is formed between adjacent two protuberances 19, the protuberances 19 are together formed with a cavity 21 for receiving a spine 14. According to FIGS. 4A to 4F and lines 4 to 7 of paragraph [0036] of the specification of US 20030150136 A1, the vertebrae 16 of the spine 14 insert into the apertures 20, respectively. According to FIG. 4F and paragraph [0041] of the specification of US 20030150136 A1, when the unidirectional support device 10 is flexed in the B direction, the vertebrae 16 restrict the protuberances 19 from approaching inward, making the unidirectional support device 10 resists bending. Such resistance to bending allows the unidirectional support device 10 to achieve substantial rigidity, to protect against inversion, eversion, or hyperextension of a flexural joint of human body. During the flexing in such direction, the protuberances 19 move closer together, thereby reducing the size of the apertures 20, until the vertebrae 16, which are disposed within the apertures 20, contact the protuberances 19 to prevent the apertures 20 from closing completely. According to paragraph [0032] of the specification of US 20030150136 A1, the exoskeleton 12 alone, without the installed spine 14, is substantially flexible in opposing directions, at least through a limited range of flexure.
It can be seen from the above description that when the unidirectional support device 10 bears a frontal impact force, the exoskeleton 12 must cooperate with the spine 14 so that the protuberances 19 can abut against the vertebrae 16 to offset the frontal impact force, thereby keeping the exoskeleton 12 straight to resist bending. In other words, if there is no spine 14 installed on the exoskeleton 12, the protuberances 19 cannot abut against the vertebrae 16, resulting the protuberances 12 to be unable to maintain straight and thus excessive bend in the B direction, and causing the user's fingers to flip upward and be fractured.
In addition, the exoskeleton 12 and the protuberances 19 are integrally formed through injection molding. Therefore, during the procedure of twisting and/or lateral bending of the unidirectional support device 10, the four corners of the protuberances 19 will not be degummed from the exoskeleton 12. Thereby, the protuberances 19 will not detach or peel off from the exoskeleton 12.
For those skilled in the art, after referring to US 20030150136 A1, there is a reasonable motivation to use injection molding technology to manufacture the reinforcing strips of US 20020184696 A1 to solve the problem of the link members 3 degumming from the carrier band 1. However, the modified reinforcing strip still cannot improve the effect of absorbing the lateral rotation force, and most of the lateral rotation force is still borne by the user's fingers, causing the user's fingers to flip laterally and be sprained.
Furthermore, according to FIGS. 2A to 2E and paragraph [0032] of the specification of US 20030150136 A1, the lip 18 of the exoskeleton 12 is arranged along the entire or part of the outer periphery of the exoskeleton 12, and the lip 18 is used to fix the exoskeleton 12 on the object of sports equipment. Therefore, the lip 18 can absorb the lateral rotation force by the effect of its elastic deformation. For those skilled in the art, after referring to the US 20030150136 A1, there is a reasonable motivation to arrange the lip 18 at the outer periphery of the reinforcing strip of US 20020184696 A1, and absorb the lateral rotation force by the lip 18, thereby preventing the user's fingers from flipping laterally and being sprained, and solves the problem of the link members 3 degumming from the carrier band 1 at the same time.
Although the four corners of each protuberances 19 form four corner cut portions and the exoskeleton 12 has a plurality of areas exposed to the corner cut portions, but the two lateral sides of each protuberances 19 are not aligned with the two long sides of the lip 18, so that there are a distance between the corner cut portions and the two long sides of the lip 18, and a distance between the areas and the two long sides of the lip 18. Because the areas are at a distance from the two long sides of the lip 18, and the lip 18 can absorb the lateral rotation force by its elastic deformation effect, the areas have no possibility of elastic deformation at all.
For those skilled in the art, US 20030150136 A1 provides two solutions that are sufficient to solve the problems of degumming as well as offsetting the lateral rotation force of the US 20020184696 A1, in addition, the specification of US 20030150136 A1 does not recite the effect of the corner cut portions and the areas. Further, the corner cut portions and the areas have no relevance with the absorption of lateral rotation force at all. Therefore, those skilled in the art have no motivation at all to respectively form corner cut portions at the four corners of the link members 3 of the reinforcing strip of US 20020184696 A1 for exposing the plurality of areas of the carrier band 1 to the corner cut portions.
In addition, as shown in FIG. 1 of US 20020184696 A1, the two wing portions of each link member 3 each has a triangular block shape. As shown in FIGS. 2A to 2D of US 20030150136 A1, the two wing portions of each protuberances 19 each has a triangular block shape. Therefore, whether the reinforcing strip or the unidirectional support device 10 have the problems of large volume, heavy weight, high preparing cost, and also increasing the burden on the fingers.
It is noted that US 20020184696 A1 only discloses how to manufacture a single reinforcing strip, and US 20030150136 A1 only discloses how to manufacture a single unidirectional support device 10. Both patent literatures do not mention how to increase storage efficiency and produce at a massive amount.
Hence, after observed the above-mentioned defects, the inventor of the present invention considers that there is still a need for further improving the glove protection insert strip structure in known protection hand gloves, and thus the present invention has been produced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
Please refer to FIGS. 1 to 3. FIG. 1 is a perspective view of the base material of the present invention. FIG. 2 is a schematic diagram of a plurality of abutment blocks 20 of the base material of the present invention separated from one of the main body 10. FIG. 3 is a side view of the base material of the present invention. As shown in FIGS. 1 to 3, the present invention provides a base material for preparing a finger protection structure, which comprises a main body 10 and a plurality of abutment blocks 20.
The main body 10 is in form of an elongated strip, has a certain extent of flexibility to be capable of being rolled and unrolled, and has an adhesive surface 11, a stressed surface 12 opposite to the adhesive surface 11, and two long sides 13.
The plurality of abutment blocks 20 are respectively bonded on the adhesive surface 11 of the main body 10 and arranged in a straight line along a length direction of the main body 10. Each abutment block 20 has two end portions 21, two lateral sides 22, and four corners 23. The corners 23 of each abutment block 20 respectively form a corner cut portion 231, the corner cut portions 231 of two adjacent abutment blocks 20 together form two first gaps 232, a plurality of areas of the main body 10 exposed to the first gaps 232 are defined as a plurality of elastic deformation areas 14. A second gap 233 is formed between the two end portions 21 of two adjacent abutment blocks 20. The two lateral sides 22 of each abutment block 20 are respectively aligned with the two long sides 13 of the main body 10.
Please refer to FIG. 4, which is a schematic diagram of one of the finger protection structures 30 of the base material of the present invention separated from the main body 10. As shown in FIG. 4, at least one finger protection structure 30 is cut out of the main body 10 along at least two of the elastic deformation areas 14 and at least one of the second gaps 233. Particularly, with a cutting tool (bot shown), the main body 10 can be firstly cut from one of the elastic deformation areas 14, then proceed to be cut along corresponding one of the second gaps 233, and finally be cut off from another opposite positioned elastic deformation area 14. Thereby, the finger protection structure 30 is cut from the main body 10.
Accordingly, the base material can be rolled for improving storage efficiency and can be unrolled for producing the finger protection structure 30 at a massive amount.
Furthermore, because there is not any obstacle in the first gaps 232, the cutting procedure by the cutting tool can be easily performed along opposite positioned two of the elastic deformation areas 14 and the corresponding one of the second gaps 233, so as to cut out the finger protection structure 30.
Please refer to FIGS. 4 to 6. FIG. 5 is a perspective view of the first embodiment of the finger protection structure 30 of the present invention. FIG. 6 is a schematic diagram of one of the abutment blocks 20 of the first embodiment of the finger protection structure 30 of the present invention separated from a base plate 31. As shown in FIGS. 4 to 6, the present invention provides a finger protection structure 30, which comprises the base plate 31 and the plurality of abutment blocks 20.
The base plate 31 is in form of an elongated strip, has a certain extent of flexibility, and has an adhesive surface 311, a stressed surface 312 opposite to the adhesive surface 311, and two long sides 313.
The plurality of abutment blocks 20 are respectively bonded on the adhesive surface 311 of the base plate 31 and arranged in a straight line along a length direction of the base plate 31. Each abutment block 20 has two end portions 21, two lateral sides 22, and four corners 23. The corners 23 of each abutment block 20 respectively form a corner cut portion 231, the corner cut portions 231 of two adjacent abutment blocks 20 together form two first gaps 232, and a plurality of areas of the base plate 31 exposed to the first gaps 232 are defined as a plurality of elastic deformation areas 314. A second gap 233 is formed between the two end portions 21 of two adjacent abutment blocks 20. The two lateral sides 22 of each abutment block 20 are respectively aligned with the two long sides 313 of the base plate 31.
Please refer to FIG. 7, which is a schematic diagram of the first embodiment of the finger protection structure 30 of the present invention assembled in a protection hand glove 100. As shown in FIG. 7, four finger protection structures 30 are respectively inserted into four finger insert portions 101 of a protection hand glove 100, so as to protect the joints of fingers such as index finger, middle finger, ring finger, and little finger.
Please refer to FIG. 8, which is a schematic diagram of the first embodiment of the finger protection structure 30 of the present invention allowing the user's finger to bend. As shown in FIG. 8, when the user wears the protection hand glove 100 on his hand and bends his fingers, the base plate 31 are bent toward its stressed surface 312 due to its flexibility, and the abutment blocks 20 separate away from each other, thereby the second gaps 233 are opened.
Generally, the ways of using balls are different for different ball sports due to different rules. However, almost all ball sports have one thing in common, that is, letting the ball fly out. Based on the rules of different ball sports, some balls are thrown by the player's hand, some are kicked by the player's foot, and some are hit with tools. When the ball flies out, there are a frontal impact force F1 and a lateral rotation force F2. In some ball sports, the player is required to catch ball. In order to avoid hurting their hands when catching ball, the player catching ball usually wear protection hand glove(s) on his hand(s). Among these ball sports required ball catching, there are strongest shooting power for football. It is because that the football is kicked towards the goal by the player's force of waist and legs, and the shooting force is very strong, so that the frontal impact force F1 and lateral rotation force F2 of football are extremely strong. Hereafter, a protection hand glove for football is taken as an example to illustrate the use state of the finger protection structure and the effects it can achieve of the present invention. However, it is not limited to this, and the finger protection structure of the present invention can also be applied to other protection hand gloves for ball sports, which can also achieve the same effect.
Please refer to FIG. 9, which is a schematic diagram of the first embodiment of the finger protection structure 30 of the present invention bearing a frontal impact force F1. As shown in FIG. 9, when the user wears the protection hand glove 100 on his hand to catch the football and the stressed surface 312 of the base plate 31 is impacted by the frontal impact force F1 of the football, the abutment blocks 20 abut against each other, the second gaps 233 are closed, and the base plate 31 straightens, so as to offset the frontal impact force F1 of the football. Thereby, the base plate 31 will not bend upwards at all, and the user's fingers will not flip upwards and be fractured.
Comparing to the unidirectional support device disclosed by US 20030150136 A1, the finger protection structure 30 of the present invention can independently offset the frontal impact force F1 without cooperating with other structures (for example, the spine 14 of US 20030150136 A1). Therefore, comparing to the unidirectional support structure 10 disclosed by US 20030150136 A1, the finger protection structure 30 of the present invention has simpler overall structure, smaller volume, lighter weight, and lower cost.
Please refer to FIG. 10, which is a schematic diagram of the first embodiment of the finger protection structure 30 of the present invention bearing lateral rotation force F2. As shown in FIG. 10, when the user wears the protection hand glove 100 on his hand to catch the football and the stressed surface 312 of the base plate 31 is impacted by the lateral rotation force F2 of the football, the base plate 31 is partially twisted to the left or right and/or bending laterally, the elastic deformation areas 314 are elastically deformed, so as to offset the lateral rotation force F2 of the football. Thereby, the base plate 31 will not be twisted and/or bent laterally at all, and the user's fingers will not flip laterally and be sprained at all. It completely solves the problem that the reinforcing strip of US 20020184696 A1 and the reinforcing strip of US 20020184696 A1 manufactured by the injection molding technology of US 20030150136 A1 cannot offset the lateral rotation force F2 of the football.
Furthermore, when the finger protection structure 30 of the present invention absorbs the lateral rotation force F2 of the football, the base plate 31 will not be twisted and/or bent laterally at all. Therefore, the corner cut portions 231 of the abutment blocks 20 will not be degummed from the base plates 31 at all, and the abutment blocks 20 will not detach or peel off from the base plates 31 at all, such that the finger protection structure 30 of the present invention can maintain the finger protecting function. It completely solves the problem of degumming of the reinforcing strip of US 20020184696 A1.
In addition, the area of the elastic deformation areas 314 of the finger protection structure 30 of the present invention is significantly smaller than the area of the lip 18 of US 20030150136 A1, while the present invention can achieve the same effect of offsetting the lateral rotation force F2 of the football. Therefore, the area of the base plate 31 of the finger protection structure 30 of the present invention can be reduced to an area smaller than the exoskeleton 12 of the unidirectional support device 10 of US 20030150136 A1. Therefore, comparing to the unidirectional support structure 10 disclosed by US 20030150136 A1, the preparing cost of the finger protection structure 30 of the present invention is relatively low.
Preferably, both the main body 10 and the base plate 31 are made of elastic material. Therefore, the elastic material can increase the elastic deformation effect of the elastic deformation areas 314, and thus can improve the effect of the elastic deformation areas 314 offsetting the lateral rotation force F2 of the football.
As shown in FIGS. 3 and 6, each corner cut portion 231 is an inclined surface relative to the main body 10 and the base plate 31, and the inclined surface is a flat surface. However, it is not limited to this, and the inclined surface may also be a concave arc surface or a convex arc surface.
As shown in FIG. 7, each corner cut portion 231 and one of the end portions 21 of each abutment block 20 form a first included angle 01 therebetween, each corner cut portion 231 and one of the lateral sides 22 of each abutment block form a second included angle θ2 therebetween, and the first included angles θ1 and the second included angles θ2 are all obtuse angles. The angles of the first included angles θ1 and the second included angles θ2 are all the same, such that the areas of the elastic deformation areas 314 are all the same. Accordingly, when the user wears the protection hand glove 100 on his hand to catch the football and the stressed surface 312 of the base plate 31 is impacted by the lateral rotation force F2 of the football, for the base plate 31, the degrees of being partially twisted to the left or right and/or bending laterally are all the same.
In other embodiments, the angles of the first included angles θ1 and the second included angle θ2 are all different, such that the areas of the elastic deformation areas 314 are all different. Accordingly, when the user wears the protection hand glove 100 on his hand to catch the football and the stressed surface 312 of the base plate 31 is impacted by the lateral rotation force F2 of the football, for the base plate 31, the degrees of being partially twisted to the left or right and/or bending laterally are all different.
In other embodiments, the angles of the first included angles θ1 and the second included angle θ2 are partly the same and partly different, such that the areas of the elastic deformation areas 314 are partly the same and partly different. Accordingly, when the user wears the protection hand glove 100 on his hand to catch the football and the stressed surface 312 of the base plate 31 is impacted by the lateral rotation force F2 of the football, for the base plate 31, the degrees of being partially twisted to the left or right and/or bending laterally are partly the same and partly different.
As shown in FIGS. 2, 3 and 5, each abutment block 20 has a block body 24 and two wing portions 25. The wing portions 25 respectively protrude from both sides of the block body 24. The height of the block body 24 relative to the main body 10 and the base plate 31 is greater than that of each wing portion 25 relative to the main body 10 and the base plate 31. As shown in FIGS. 3 and 5, each wing portion 25 has a flat shape. Both ends of each wing portion 25 are two of the corners 23 of each abutment block and respectively form a corner cut portion 231, such that each abutment block 20 has an octagonal shape.
The two wing portions of the link members 3 of US 20020184696 A1 and the two wing portions of the protuberances 19 of US 20030150136 A1 each has a triangular block shape, and the volume of the wing portion having a triangular block shape is significantly larger than that of the wing portion 25 having a flat shape. Therefore, comparing to the reinforcing strip of US 20020184696 A1 and the unidirectional support device 10 of US 20030150136 A1, the finger protection structure 30 of the present invention has the advantages such as small size, light weight, relatively low preparing cost, and also being capable of reducing the burden on fingers.
Preferably, the abutment blocks 20 are bonded on the adhesive surface 11 of the main body 10 by ultrasonic welding technology. However, it is not limited to this, and the abutment blocks 20 can also be bonded to the adhesive surface 11 of the main body 10 by glue or other bonding means.
Please refer to FIG. 11, which is a schematic diagram of the second embodiment of the finger protection structure of the present invention assembled in a protection hand glove 200. The second embodiment is different from the first embodiment in that the finger protection structure 30 further comprises a fixing plate 32 connected to one end of the base plate 31 and located inside the protection hand glove 200. Accordingly, the second embodiment can not only protect the fingers, but also further protect the back of the hand.
In summary, the present invention has excellent progressive practicality in similar products. At the same time, after thoroughly searching the domestic and foreign technical information about this type of structure, the same structure has not been found in the literature. Therefore, the present invention actually meets patentable the requirements, and the present application is filed in accordance with the Patent Law.
Although the present invention has been described with reference to the preferred embodiments thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
