Description

TECHNICAL FIELD

The present invention relates to a handgrip exercising device, and in particular to a handgrip exercising device which serves to enhance a user's gripping strength with the aid of a handgrip exercise using a plurality of body parts each made of an elastic material such as silicon and further serves to selectively increase a hand gripping strength by providing an elliptical elastic pipe in the interior, thus performing a hand gripping exercise in an optimum state depending on the strength of a user's finger.

BACKGROUND

A handgrip exercising device is a kind of exercise devices generally used to strengthen the muscles of a hand or a forearm and is portable and easy to use regardless of exercise places and time.
The conventional handgrip exercising device has a pair of operation arms of which one side is connected with a coil type spring, thus being formed in an upside down V-shape. The operation arms serve elastically to keep a certain distance between them about the coil type spring.
In the conventional handgrip exercising device, a user grips a pair of operation arms with a hand and repeats gripping and ungripping operations, during which a coil type spring connected to one side of each operation arm is elastically bent. The operations that gripping force is applied to an extent to overcome the elastic force of the spring helps strengthen the muscles of a hand or a forearm.
The conventional handgrip exercising device has a problem that gripping force is not uniformly applied to the whole portions of each palm in the course of exercise due to a cylindrical rod-shaped structure of an operation arm while a user repeatedly performs gripping and ungripping operations using the cylindrical shaped operation arms, as a result of which a uniform muscle exercise is not performed over the whole portions of the hand and the fingers. In worse case, a muscle pain might occur due to a partial force concentration at a finger muscle.
The conventional handgrip exercising device is directed to performing hand muscle exercises based on the operations that one coil type spring is repeatedly contracted and released. The operation arms and the coil type spring are connected in an integrated structure, so the users having different strengths of hands and fingers cannot control the strengths of a conventional handgrip exercising device.
In an attempt to overcome the above problems, a strength-controllable handgrip exercising device is disclosed, the exercise level of which can be adjustable based on the strength and size of a user's hand by adjusting a distance between an operation arm and a spring.
However the conventional handgrip exercising device has a problem that forces are not uniformly applied to the whole portions of a palm when in use due to a cylindrical rod shape of an operation arm, so a user cannot perform the uniform muscle exercise over the whole portions of a user's hand and fingers. In worse case, a finger's muscle is partially over strengthened or loaded, thus causing a muscle pain.

SUMMARY

It is an object of the present invention to provide a handgrip exercising device which serves to perform a hand gripping exercise smoothly by enhancing a hand gripping operation, not causing a partial muscle pain at a user's finger, while performing a uniform muscle exercise over the whole portions of a hand and fingers in such a way that gripping and ungripping forces are uniformly distributed to the whole portions of a palm in the curse of hand gripping exercises.
It is another object of the present invention to provide a handgrip exercise which helps perform a handgrip exercise in optimum state depending on the strength of a user's finger in such a way that a handgrip strength can be selectively increased by further providing an elliptical elastic pipe in the interior of a body part formed of an elastic material such as silicon.
To achieve the above objects, there is provided a handgrip exercising device for a muscle strength exercise of a hand and fingers which comprises a body part which includes a plurality of cylindrical members each made of an elastic material; and an adhesive part which adheres the cylindrical members of the body part in a juxtaposed shape, thus allowing a user to do hand gripping exercise using an elastic recovery force of each cylindrical member as the user grips the body part.
To achieve the objects, there is provided a handgrip exercising device for a muscle strength exercise of a hand and fingers which comprises a body which is integral by injection-molding an elastic material; and a space part which is formed of a plurality of through holes juxtaposed in a longitudinal direction of the body part in the interior of the body part, with the air freely flowing through the through holes, with the shape transformation of the body part being easily performed, thus allowing a user to do hand gripping exercise using an elastic recovery force as the user shape-transforms the body part on the basis of a hand gripping force.
According to the present invention, a cylindrical member is made using an elastic material such as silicon; and three to ten cylindrical members are bonded in parallel, thus forming a body part. A body part might be formed by integrally injection-molding an elastic material. A user can exercise gripping the body part with a hand with the aid of an elastic force of a cylindrical member or a space part.
The handgrip exercising device serves to perform a hand gripping exercise smoothly by enhancing a hand gripping operation, not causing a partial muscle pain at a user's finger, while performing a uniform muscle exercise over the whole portions of a hand and fingers in such a way that gripping and ungripping forces are uniformly distributed to the whole portions of a palm in the curse of hand gripping exercises.
The handgrip exercise helps perform a handgrip exercise in optimum state depending on the strength of a user's finger in such a way that a handgrip strength can be selectively increased by further providing an elliptical elastic pipe in the interior of a body part formed of an elastic material such as silicon.

DETAILED DESCRIPTION OF EMBODIMENTS

The preferred embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the handgrip exercising device 100 according to an embodiment of the present invention comprises a body part 120 formed of a plurality of cylindrical members 110 each made of an elastic material.
The body part 120 is formed of a cylindrical member 110 made of a smooth elastic material such as a silicon material having a good gripping feeling, so a user do a hand gripping exercise using an elastic recovery force of the cylindrical member 110.
As shown in FIGS. 1 and 2, it is preferred that the body part 120 is formed of three to 10 cylindrical members 110 having same diameters.
Alternatively, as shown in FIGS. 3A and 3B, the body part 120 might be formed of three to ten cylindrical members 110 having different diameters.
It is preferred that the cylindrical members 110 are made in a silicon tube structure, the both ends of which are open for air to freely flow into the same. However, the present invention is not limited in this regard as other materials known to these skilled in the art to which the present invention pertains, may be substituted without subtracting from the broader aspects of the present invention.
With the aid of the structure the both ends of which are open, the body part 120 formed of a plurality of cylindrical members 110 can be freely shape-transformed by a user's hand gripping force.
The handgrip exercising device 100 according to an embodiment of the present invention comprises an adhesive part 130 by which the cylindrical members 110 of the body part 120 are adhered in a juxtaposed shape. The adhesive part 130 is formed of a known strong bond, which is coated on the outer surface of each cylindrical member 110, thus integrally bonding the cylindrical members 110.
In the handgrip exercising device 100 according to an embodiment of the present invention, the entire diameter of the same can be adjusted on the basis of decreasing or increasing the number of the cylindrical members 10, which are to be adhered by the adhesive part 130, in case that the cylindrical members 10 have same diameters. For example, in case of an adult having a larger size hand, the large diameter “D” is needed. In this case, six to ten cylindrical members 110 are integrally bonded using an adhesive part 120, thus easily manufacturing a large size device.
In case of a girl or a kind having a smaller size hand, three to five cylindrical members 110 are integrally adhered using an adhesive part 130 to obtain a smaller size diameter “d”, thus manufacturing a smaller size device.
As shown in FIGS. 3A and 3B, the handgrip exercising device 100 according to an embodiment of the present invention might be formed of a plurality of cylindrical members 110 having different diameters.
In the structure of different diameters, each cylindrical member 110 of the body part 120 comprises a larger diameter cylindrical member 110 a, and a smaller diameter cylindrical member 110 b. The cylindrical member 110 can be manufactured in a larger size diameter for an adult or a person having a larger size hand or can be manufactured in a smaller size diameter or a girl or a kid having a smaller size hand in combination with the large size diameter cylindrical members 110 a and the smaller size diameter cylindrical members 110 b.
As shown in FIG. 4, the handgrip exercising device 100 according to an embodiment of the present invention, the hand gripping force can be adjusted by further inserting the elastic pipe 140 into the interior of the cylindrical member 110. The elastic pipe 140 has an elliptical cross section and is made of the same silicon material as the cylindrical member 110 and is tightly inserted into the interior of the cylindrical member 110.
Since the elastic pipe 140 can elastically withstand against the operation that the cylindrical member 110 is inwardly pressed in the interior of each cylindrical member 110, so a user needs a larger hand gripping force, and the body part 120 in which the elastic pipe 140 is engaged in the interior of the cylindrical member 110 needs a larger force as compared to the body part 20 which does not have the elastic pipe 140. So, the above construction is good for an adult having a larger hand gripping force.
As shown in FIG. 2, a user does a hand gripping exercise, holding the body part 120 and gripping and ungripping with the aid of the elastic recovery force of the cylindrical members 110.
When a user holds a handgrip device 100 according to an embodiment of the present invention, as shown in FIG. 5A, each body part 120 formed of a plurality of cylindrical members 110 receives a pressing force P1 in the direction of the diameter of the body part 120, and as shown in FIG. 5B, the intermediate portion of the body part 120 receiving a user's hand gripping force is pressed in the direction of the diameter, so the diameter is shape-transformed in the decreased state.
In the above state, when the use removes a hand gripping force, the body part 120 recovers to the initial state with the aid of the elastic recovery force P2 of the cylindrical members 110, and the diameter of the intermediate portion of the body part 120 recovers.
The user can repeatedly perform the hand gripping exercise over the above procedures in natural postures. Since the cylindrical members 110 are made of smooth and elastic materials such as silicon, which feels soft, the user can easily grip when in use. Since the cylindrical members 110 of the body part 120 surround the whole portions of the user's hand in the course of exercise, griping force can be uniformly applied to the whole portions of the hand.
The user can do uniform muscle exercises over the whole portions of the hand while avoiding over force from being applied to a partial portion of the finger, thus basically preventing a partial muscle pain at the finger muscles, which leads to easier hand grapping exercises.
The handgrip exercising device 100 according to an embodiment of the present invention might further equip with an elliptical elastic pipe 140 at an inner side of each cylindrical member 110, thus selectively increasing the strength of hand gripping, which results in the optimum hand gripping exercise depending on the strength of user's finger.
FIGS. 6 to 11 are views illustrating a handgrip device 200 according to another embodiment of the present invention.

The handgrip exercising device 200 according to another embodiment of the present invention serves to provide a user with a function of performing a hand gripping exercise by using an elastic recovery force of the body part 210 after the user holds the body part 210 with a hand and converts into a hand gripping force.
A shown in FIG. 6, it is preferred that the handgrip exercising device 200 according to another embodiment of the present invention is characterized in that the outer surface of the body part 210 is formed of a curved surface 214 formed at a regular interval at a certain arc curvature in the circumferential direction, and the space part 230 comprises a through ole 232 formed of a plurality of circular holes 236 formed in the interior of the body part 210 in the longitudinal direction of the body part 210, and a polygonal hole 238 formed at its center portion.
As shown in FIG. 7, it is preferred that the body part 210 is characterized in that the outer surface of the body part 210 is formed of a straight polygonal surface 216 formed at a regular interval in a circumferential direction, and the space part 230 comprises a through hole 232 formed of a plurality of circular holes 236 formed in a longitudinal direction of the body part 210 in the interior of the body part 210, and a polygonal hole 238 formed at its center portion.
It is preferred that the body part 210, as shown in FIG. 8, is characterized in that the outer surface of the body part 210 is formed of a curved surface 214 at a regular interval at an arc curvature in a circumferential direction, and the space part 230 comprises a through hole 232 formed of a plurality of circular holes 236 juxtaposed in the longitudinal direction of the body part 210 in the interior of the boy part 210.

In the structure of the handgrip exercising device 200 according to another embodiment of the present invention, as shown in FIG. 4, the space part 230 serves to adjust the strength of hand gripping by further providing the elastic pipe 140 in the interior of the through hole 232, and the elastic pip 140 is formed of an elliptical cross section and is made of the same silicon material as the body part 210 and is tightly and fixedly inserted into the interior of the through hole 232.
In the handgrip exercising device 200 according to another embodiment of the present invention, a user holds the body part 210 and performs gripping and ungripping exercises with the aid of the elastic recovery force generating upon the shape transformation of the space part 230.
In this case, when a user grips the handgrip exercising device 200 according to another embodiment of the present invention, the space part 230 formed of a plurality of through holes 232 receives the force applied in the direction of the diameter of the body part 210, and the intermediate portion of the body part 210 is pressed in the direction of the diameter and is shape-transformed in a shape that the intermediate is reduced. At this time, the space part 230 provides a space in which the body part 210 is shape-transformed as the internal air of the though holes 232 are discharged to the outside, thus easily shape-transforming the body part 210 and storing the elastic recovery force.
In this state, when the user eliminates the gripping force, the body part 210 recovers to its initial state due to the inherent characteristics of material, and the trough holes 232 are shape-transformed and recover to their initial states.
Through the above procedures, the user can repeatedly and naturally perform the hand gripping exercises in a state that the user can naturally and smoothly grip the body part 210 since the body part 210 is made of an elastic material like a silicon material which feels soft. Since the hand gripping exercise are performed with the body part 210 being enough surrounded by the whole portions of the palm of the user, the gripping force can be uniformly applied to the whole portions of the palm.
The user can do uniform muscle exercise over the whole portions of the hand and the fingers without applying a partial over load to a certain finger muscle and causing a partial muscle pain, as a result of which it is possible to more efficiently perform a hand gripping exercise in safe.
