Description

Grip strengthener and manufacturing method thereof TECHNICAL FIELD

[0001] The present application relates to the field of grip strengthener, in particular to a grip strengthener and manufacturing method thereof. BACKGROUND

[0002] With the pursuit of healthy life becoming higher and higher, people have become more and more aware of the importance of exercising and strengthening their bodies. As a device for exercising grip strength, grip strengtheners have become a common tool for people's daily exercise. Users mainly achieve grip strength exercise by grasping a specific position of the grip strengthener and resisting the elastic force of the grip strengthener. However, there are some problems in the actual application of the existing grip strengtheners.

[0003] Specifically, some grip strengtheners lack anti-falling structures. Some users with hand injuries, lack of hand strength, or stiff fingers cannot hold the grip strengthener tightly. In this way, after placing the grip strengthener in the user's hand, the grip strengthener inevitably falls.

[0004] Some grip strengtheners fix and completely isolate each position for placing different fingers, so that each finger must be placed in the corresponding position. However, for users with stiff fingers and low finger flexibility, on the one hand, users have difficulty placing each finger in the corresponding position independently; on the other hand, even if the user's fingers are placed in the corresponding position, the user's use comfort is low. And different users have different palm sizes and habitual spacings when each finger is separated, and the fixed and completely separated position arrangement affects the application range and use comfort of the grip strengthener.

[0005] Some grip strengtheners are designed in one piece, and the materials of each part are the same. However, the roles played by different parts and the requirements for materials are different. For example, some parts need to be more solid, have better stretch resistance, and have stronger hardness; some parts need lower hardness, for example, the part to be held, if the hardness is large, the user's resilience is small even if the user uses force to hold tightly. Especially for users with hand injuries or defects, the user's hand strength is not strong, and if the hardness of the part to be held is large, the holding difficulty is large.

[0040] The terms and words used in the following description and claims are not limited to the bibliographical meanings, but are merely used to enable a clear and consistent in understanding of the application. Therefore, it is apparent to those skilled in the art that the following description of various embodiments of the present application is provided for illustration purpose only and not for the purpose of limiting the application as defined by the appended claims and their equivalents.

[0041] It is to be understood that the term "one" or "a" or "an" shall not be construed as limiting the number of components to a single component, but rather shall be read to cover the components individually as well as in the plural. In other words, "one" or "a" or "an" shall be construed as meaning "at least one" or "one or more" unless otherwise indicated.

[0042] Although ordinal numbers such as "first", "second", or the like will be used in describing various components, they are used to distinguish one component from another component. For example, a first component could be termed a second component, and similarly, a second component could be termed a first component without departing from the teachings of the present disclosure. The term "and / or" as used herein comprises any and all combinations of one or more of the associated listed items.

[0043] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising", when used in this specification, specify the presence of stated features, integers, steps, operations, elements, components and / or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0044] With reference to FIGS. 1-23 of the accompanying drawings, a hand gripper 1 according to an embodiment of the present disclosure is illustrated in the following description. In the present embodiment, the hand gripper 1 can be used not only for daily hand grip exercise, but also for hand rehabilitation training. The hand gripper 1 comprises a holding portion 10 and a retaining portion 20. The holding portion 10 is configured to be held by a user. The holding portion 10 has a first connecting portion 110 and a second connecting portion 120, wherein the first connecting portion 110 is opposite to the second connecting portion 120. The retaining portion 20 extends between the first connecting portion 110 of the holding portion 10. The retaining portion 20 and the holding portion 10 enclose a finger placement space 101 therebetween, wherein the finger placement space 101 is located between the retaining portion 20 and the holding portion 10 and is configured to place more than one finger, for example, the index finger, the middle finger, the ring finger and the little finger.

[0045] For the convenience of the following description of the hand gripper 1, in the present disclosure, the holding portion 10 is located at the upper side, and the retaining portion 20 is located at the lower side. Accordingly, the holding portion 10 is located above the finger placement space 101, and the retaining portion 20 is located below the finger placement space 101.

[0046] It is worth mentioning that, in the present application, the holding part 20 is arranged between the two connecting parts of the holding part 10, which can prevent the hand from falling to a certain extent. Specifically, as shown in FIG. 2, when the user holds the holding part 10, the palm of the user faces the holding part 10, and the back of the hand faces the holding part 20. As shown in FIG. 3, when the user does not hold the handgrip 1 tightly or releases the handgrip 1, the holding part 20 above the finger space 101 and close to the back of the hand limits the palm between the holding part 10 and the holding part 20, which can prevent the handgrip 1 from falling out of the palm of the user to a certain extent, and can improve the applicability of the handgrip 1 to users with insufficient hand strength. That is, the holding part 20 forms an anti-falling structure of the handgrip 1.

[0047] It is worth mentioning that the size of the finger space 101 should not be too large or too small. When the width of the finger space 101 is too large, when the user does not hold the handgrip 1 tightly or releases the handgrip 1, the handgrip 1 is easy to fall off the hand. When the width of the finger space 101 is too small, it may hinder the fingers from entering the finger space 101. The width refers to the size in the upward direction, i.e., the size in the first direction L1. When the length of the finger space 101 is too small, it may also hinder the fingers from entering the finger space 101. The length refers to the size in the second direction L2.

[0048] In an embodiment of the present application, the width of the finger space 101 ranges from greater than or equal to 0.5 cm to less than or equal to 5.0 cm. The length of the finger space 101 ranges from greater than or equal to 5.0 cm to less than or equal to 15.0 cm.

[0049] In addition, the holding part 20 can also assist in holding to a certain extent. Specifically, if the user's hand is relatively stiff, when the fingers stretch towards the holding part 10, the holding part 20 above the finger space 101 generates a downward force on the hand, forcing the palm to hold the holding part 10, thereby assisting the user in handgrip training.

[0050] It is also worth mentioning that the finger placement space 101 is an open space, that is, not completely separated into multiple independent spaces isolated from each other, so that the finger placement position of the grip strengthener 1 has high flexibility, so that it has a wide range of applications, for example, it can be applied to users with different palm sizes or different habitual spacings when the fingers are separated, and it can also be applied to users with low finger flexibility. Thanks to the high flexibility of the finger placement position of the grip strengthener 1, the grip strengthener 1 has high comfort of use, so that the user can flexibly adjust the position of the fingers.

[0051] The specific structure of the grip part and the holding part 20 will be described below.

[0052] The holding part 10 is a flexible elastic body. Optionally, the holding part 10 can be made of foamed material, or other materials. The elasticity of the holding part 10 can be adjusted by adjusting the material and manufacturing process of the holding part 10. The holding part 10 with different elasticity or hardness can meet different groups of people with different grip strength, for example, the holding part 10 that is relatively soft and easy to deform can meet people with poor grip strength; the holding part 10 that is relatively hard and not easy to deform can meet people with large grip strength.

[0053] It is worth mentioning that the holding part 10 includes a holding inner part 11 and a holding surface layer 12. The holding surface layer 12 is wrapped outside the holding inner part 11. The holding surface layer 12 is relatively smooth, so that the surface of the holding part 10 is relatively flat. Here, flat means low wrinkle.

[0054] It is also worth mentioning that the holding inner part 11 can be made of the same material, or multiple parts can be formed by multiple materials respectively, and then the holding inner part 11 is made. Accordingly, in an example of the present application, as shown in FIG. 6, the holding inner part 11 includes an inner part one 111 and an inner part two 112, wherein the inner part two 112 is wrapped outside the inner part one 111, and the hardness of the inner part two 112 is greater than that of the inner part one 111, so that the holding inner part 11 is soft inside and hard outside.

[0055] It should be understood that in other examples of the present application, the hardness of the inner part two 112 can be less than that of the inner part one 111, so that the holding inner part 11 is hard inside and soft outside.

[0056] The holding surface layer 12 can be closely attached to the holding inner part 11, as shown in FIG. 4, for example, the holding surface layer 12 is coated on the holding inner part 11. The holding surface layer 12 can also be loosely and with a gap from the holding inner part 11 outside the holding inner part 11, as shown in FIG. 5, wherein the holding surface layer 12 can be made of silicone or other materials; the holding part 20 is connected to the holding surface layer 12.

[0057] Optionally, the holding portion 10 has a plurality of air holes 107 to facilitate air in the holding portion 10 to be discharged when the holding portion 10 is pressed.

[0058] The overall shape of the holding portion 10 is not limited in the present application. The holding portion 10 has a holding upper surface 102 and a holding lower surface 103, and two holding side surfaces 104. The holding lower surface 103 is opposite to the holding upper surface 102 in a first direction Ll, and the two holding side surfaces 104 are opposite to each other in a second direction L2. The holding side surfaces 104 extend between the holding upper surface 102 and the holding lower surface 103. The holding upper surface 102 faces the finger placement space 101. The holding lower surface 103 faces away from the finger placement space 101. When a user holds the holding portion 10, the user can place the index finger, the middle finger, the ring finger and the little finger on the holding upper surface 102, and place the thumb on the holding lower surface 103. That is, when a user holds the holding portion 10, the holding upper surface 102 is adapted to place the index finger, the middle finger, the ring finger and the little finger, and the holding lower surface 103 is adapted to place the thumb.

[0059] Preferably, the holding upper surface 102 is curved and protrudes upwardly towards the finger placement space 101, so that the holding upper surface 102 is adapted to the bending direction of the index finger, the middle finger, the ring finger and the little finger when the fingers are bent. Preferably, the holding lower surface 103 is curved and protrudes downwardly away from the finger placement space 101, so that the holding lower surface 103 is adapted to the bending direction of the thumb.

[0060] In an embodiment of the present application, as shown in FIGS. 9 to 14, the holding portion 10 has a spindle shape, and the entire outer surface is curved. Accordingly, the holding upper surface 102 is curved and protrudes upwardly towards the finger placement space 101. The holding lower surface 103 is curved and protrudes downwardly away from the finger placement space 101. The holding side surfaces 104 are also curved.

[0061] It should be appreciated that the holding portion 10 can have other shapes.

[0062] In some embodiments, the gripping upper surface 102 of the gripping portion 10 is recessed in multiple locations, which can distinguish the placement of fingers to some extent. Accordingly, the gripping portion 10 has multiple recesses 106 recessed downward from the gripping upper surface 102. When a user holds the gripping portion 10, fingers can be placed in the multiple recesses 106 respectively. It is worth mentioning that although the recesses 106 can distinguish the placement of fingers, on the one hand, the gripping portion 10 itself is a flexible elastomer, and the recesses 106 are shallow, so that the placement of fingers is mainly guided to some extent, and the placement of fingers is less restricted; on the other hand, the recesses 106 are not completely isolated, so that the user does not have to place fingers in the specified positions according to the established rules.

[0063] The number of the recesses 106 is not limited in the present application, which can be 1, 2, 3, or more. In an example of the present application, the number of the recesses 106 is 2. Accordingly, in this example, the gripping portion 10 has two recesses 106, as shown in FIG. 16. The two recesses 106 are suitable for placing two fingers, for example, the index finger and the middle finger, or the middle finger and the ring finger, or the ring finger and the little finger, respectively. In another example of the present application, the number of the recesses 106 is 4. Accordingly, in this example, the gripping portion 10 has four recesses 106, as shown in FIGS. 17-23. The four recesses 106 are suitable for placing the index finger, the middle finger, the ring finger, and the little finger, respectively.

[0064] In the embodiments of the present application, the gripping portion 10 has a first gripping end portion 130 and a second gripping end portion 140. The first gripping end portion 130 and the second gripping end portion 140 are opposite in the third direction L3. In the embodiments of the present application, the first gripping end portion 130 serves as the first connecting portion 110, and the second gripping end portion 140 serves as the second connecting portion 120. That is, the holding portion 20 extends between the first gripping end portion 130 and the second gripping end portion 140 of the gripping portion 10.

[0065] The materials of the various parts of the grip strengthener 1 are designed according to the needs to meet the performance requirements of different parts. For example, the gripping portion 10 is suitable for being held, and the holding portion 20 is stretch-resistant. Alternatively, the holding portion 20 is an elastomer or plastic or other materials. In an embodiment of the present application, the material of the holding portion 20 is different from the material of the gripping portion 10.

[0066] The parameters of the holding portion 20 and the gripping portion 10 are also selected according to requirements. In an embodiment of the present application, the tear strength of the holding portion 20 is greater than or equal to the tear strength of the gripping portion 10. The tear strength of the holding portion 20 ranges from greater than or equal to 3.0 KG / cm and less than or equal to 10.0 KG / cm, and the tear strength of the gripping portion 10 ranges from greater than or equal to 0.1 KG / cm and less than or equal to 3.0 KG / cm. The tear strength refers to the maximum load per unit size when an object is torn. Alternatively, the tear strength can be tested according to the SATRA TM65 standard. The Shore hardness of the gripping portion 10 ranges from greater than or equal to 0 degrees and less than or equal to 50 degrees, and the Shore hardness of the holding portion 20 ranges from greater than or equal to 10 degrees and less than or equal to 50 degrees. The Shore hardness can be tested by a Shore hardness tester of model Asker C. The density of the gripping portion 10 ranges from greater than or equal to 0.15 g / cm 3 and less than or equal to 0.50 g / cm 3 . The density of the holding portion 20 ranges from greater than or equal to 0.25 g / cm 3 and less than or equal to 0.50 g / cm 3 . The density can be tested according to the DIN EN ISO 845 standard.

[0067] In one example of the present application, the Shore hardness of the gripping portion 10 is 0 degrees, the density of the gripping portion 10 is 0.15 g / cm 3 , and the tear strength of the gripping portion 10 is 0.1 KG / cm.

[0068] In another example of the present application, the Shore hardness of the gripping portion 10 is greater than or equal to 40 degrees and less than or equal to 50 degrees, the density of the gripping portion 10 is 0.50 g / cm 3 , and the tear strength of the gripping portion 10 is 3.0 KG / cm.

[0069] In one example of the present application, the Shore hardness of the holding portion 20 is 15 degrees, the density of the holding portion 20 is 0.25 g / cm 3 , and the tear strength of the holding portion 20 is 3.0 KG / cm.

[0070] In another example of the present application, the Shore hardness of the holding portion 20 is 40 degrees, the density of the holding portion 20 is 0.50 g / cm 3 , and the tear strength of the holding portion 20 is 10.0 KG / cm.

[0071] In an embodiment of the present application, the holding part 20 comprises a holding inner core 2010 and a holding outer layer 2020, as shown in FIG. 7. The holding outer layer 2020 is located outside the holding inner core 2010. The tensile strength of the holding inner core 2010 is greater than that of the holding outer layer 2020. The holding inner core 2010 can be made of silica gel or other materials with high tensile strength.

[0072] The shape of the holding part 20 is not limited in the present application. The holding part 20 has opposite holding upper surface 201 and holding lower surface 202, and two holding side surfaces 203. The holding upper surface 201 and the holding lower surface 202 are opposite in the first direction L1. The two holding side surfaces 203 are opposite in the second direction L2. The holding side surfaces 203 extend between the holding upper surface 201 and the holding lower surface 202. The holding lower surface 202 faces the finger placement space 101.

[0073] In an example of the present application, the holding lower surface 202 is arc-shaped, and the holding lower surface 202 has a uniform curvature. Alternatively, the cross section of the holding part 20 is circular.

[0074] It should be understood that the shape of the holding part 20 can also be other shapes.

[0075] In an example of the present application, the part of the holding part 20 connected to the holding part 10 is embedded in the holding part 10. Preferably, the part of the holding part 20 connected to the holding part 10 is embedded in the holding part 10 by insert molding. For example, the molded holding part 20 is placed in a mold, and the manufacturing material of the holding part 10 is added to the mold, so that the holding part 20 is at least partially immersed in the manufacturing material of the holding part 10, so that after the holding part 10 is molded, the holding part 20 is at least partially embedded in the holding part 10. The embedded connection and the insert molding processing make the holding part 20 and the holding part 10 more closely connected.

[0076] The holding part 20 comprises a holding main body part 21, a first holding connecting part 22 and a second holding connecting part 23. The holding main body part 21 has a main body first end part 211 and a main body second end part 212. The first holding connecting part 22 is connected to the main body first end part 211 and protrudes from the main body first end part 211. The second holding connecting part 23 is connected to the main body second end part 212 and protrudes from the main body second end part 212. The first holding connecting part 22 is embedded in the first connecting part 110 of the holding part 10; the second holding connecting part 23 is embedded in the second connecting part 120 of the holding part 10.

[0077] In this example, the first holding connecting part 22 has a smaller radial dimension than the first end part 211 of the main body. The second holding connecting part 23 has a smaller radial dimension than the second end part 212 of the main body. That is, the part of the holding part 20 inserted into the holding part 10 has a smaller radial dimension, which facilitates the insertion of the holding part 20 into the holding part 10 and the complete embedding of the holding part 20 into the holding part 10.

[0078] It should be understood that the first holding connecting part 22 can also have the same radial dimension as the first end part 211 of the main body.

[0079] It should be understood that the holding part 20 can also be connected to the holding part 10 in other ways, for example, by screwing. In one example of the present application, the first connecting part 110 of the holding part 10 has an internal thread, forming a nut structure; the second connecting part 120 of the holding part 10 has an internal thread, forming a nut structure; the part of the holding part 20 connected to the holding part 10 has an external thread, forming a screw structure; and the external thread of the holding part 20 is adapted to the internal thread of the holding part 10. In another example of the present application, the first connecting part 110 of the holding part 10 has an external thread, forming a screw structure; the second connecting part 120 of the holding part 10 has an external thread, forming a screw structure; the part of the holding part 20 connected to the holding part 10 has an internal thread, forming a nut structure; and the internal thread of the holding part 20 is adapted to the external thread of the holding part 10.

[0080] In another example of the present application, the holding part 20 can be connected to the holding part 10 by gluing or other materials.

[0081] In the embodiment of the present application, the first end part 211 of the main body of the holding part 20 is adjacent to the holding part 10 and forms a first vortex groove 205 with the holding part 10. The second end part 212 of the main body of the holding part 20 is adjacent to the holding part 10 and forms a second vortex groove 206 with the holding part 10.
