Description
TECHNICAL FIELD
[0001] 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
[0002] 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.
[0003] 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.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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
[0009] 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.
[0010] 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.
[0011] 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.
[0012] 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.
[0013] 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.
[0014] 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.
[0015] 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
[0028] The preferred embodiments of the present invention will be
described with reference to the accompanying drawings.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] In the structure of different diameters, each cylindrical
member 110 of the body part 120 comprises a larger diameter
cylindrical member 110a, and a smaller diameter cylindrical member
110b. 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 110a and the smaller size diameter
cylindrical members 110b.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] 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.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] FIGS. 6 to 11 are views illustrating a handgrip device 200
according to another embodiment of the present invention.
[0049] The handgrip exercising device 200 according to another
embodiment of the present invention comprise a body part 210 made
by injection-molding an elastic material.
[0050] The body part 210 is preferably made of a silicon material
which has an excellent elastic recovery force and feels smooth and
good when gripped by a user's hand.
[0051] The body part 210 comprises a space part 230 formed of a
plurality of through holes 232 juxtaposed arranged in the interior
in the longitudinal direction of the body part 210, thus allowing
air to freely flow through the through holes and producing an
easier shape transformation of the body part 210 with the aid of
the stored elastic recovery force.
[0052] 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.
[0053] 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.
[0054] 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.
[0055] 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.
[0056] It is preferred that the body part 210 is characterized in
that the outer surface of the body part 210, as shown in FIG. 9, is
formed of a straight polygonal surface 216 at a regular interval in
a polygonal shape 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 body part 210.
[0057] 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.
[0058] 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.
[0059] 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.
[0060] 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.
[0061] 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.
[0062] 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.
[0063] The handgrip exercising device 200 according to another
embodiment of the present invention is directed to further
providing an elliptical elastic pipe 140 at the inner side of each
through hole 232 forming the space part 230, so the user can easily
and selectively increase the hand gripping strength, whereby the
optimum hand gripping exercises can be performed depending on a
user's finger strength.
[0064] As the present invention may be embodied in several forms
without departing from the spirit or essential characteristics
thereof, it should also be understood that the above-described
examples are not limited by any of the details of the foregoing
description, unless otherwise specified, but rather should be
construed broadly within its spirit and scope as defined in the
appended claims, and therefore all changes and modifications that
fall within the meets and bounds of the claims, or equivalences of
such meets and bounds are therefore intended to be embraced by the
appended claims.
