Description

{WEIGHT EXERCISE APPARATUS}

The present invention relates to a weight exercising apparatus. More specifically, unlike a general dumbbell or a dumbbell having a separate weight, in which movement is performed in the same manner as a general dumbbell or a dumbbell, a weight movement can be performed using a dynamic load caused by an elastic force, Which is easy to carry, and is easy to carry and carry, so that it is possible to carry out weight movement more conveniently at any time and anywhere.

As the living standards of modern people improve their interest in health, life sports that protect their health through various exercises are becoming common. Among them, there is a weight exercise device which improves the muscle strength through the exerciser, which is to perform a muscle exercise with respect to the upper body or the lower body by using a hand or a foot.

One of the most commonly used weight exercises is the dumbbell. The dumbbell is basically designed to strengthen the shoulder or arm muscles, and is composed of a weight attached to both ends of the handle bar located at the center.

Since the fitness dumbbell of the dumbbell is manufactured in such a way that the handle bar and the weight are integrally formed, the user uses the dumbbell to exercise using only a certain weight of the dumbbell during exercise. Particularly, the conventional dumbbell conventionally exercises in a monotonous way of lifting by using an arm, so that there is a problem that the user may easily lose interest in training and cause injury.

In addition, since the integral dumbbell can not change the weight of the dumbbell, various dumbbells having various weights are required for various exercises, which requires a lot of space for arranging, and also there is an inconvenience that a plurality of dumbbells must be purchased.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a perspective view schematically showing an outline of a weight exercising apparatus according to an embodiment of the present invention, FIG. 2 is a sectional view schematically showing the internal structure of a weight exercising apparatus according to an embodiment of the present invention, 3 is a cross-sectional view taken along the line "AA" in Fig. 2 for explaining an elastic member according to an embodiment of the present invention, Fig. 4 is a view for explaining the operation state of the rotation sensor module according to an embodiment of the present invention And FIG. 5 is a view exemplarily showing a movement operation using a weight movement mechanism according to an embodiment of the present invention.

The weight lifting mechanism according to an embodiment of the present invention is constructed in the form of a dumbbell so as not to generate a dynamic load due to weight, but to generate a dynamic load by an elastic restoring force. The lifting rod includes a pull rod 100, ), An elastic member (300), and an operation cable (400).

The handle bar 100 is formed long in one direction so that the handle bar 100 can be held by the user. The handle bar 100 may be formed in a cylindrical shape similar to a general dumbbell handle bar, but may be changed into various shapes according to the needs of the user. In addition, a plurality of non-slidable protrusions (not shown) may be formed on one side of the outer circumferential surface to prevent slippage.

The pull rod 100 includes a hollow cylindrical body member 110 which forms a middle portion in the longitudinal direction of the pull rod 100 and a hollow cylindrical body member 110 which is coupled to both ends of the body member 110 to rotate the rotary body 200 And a central shaft member 120 constituting a center shaft 121. [ The central shaft member 120 may be formed in a hollow cylindrical shape, and the body member 110 may be formed in a hollow cylindrical shape to form a receiving space therein. The body member 110 and the central shaft member 120 may be detachably coupled to each other and may be coupled in various coupling schemes, for example, screwed or fit-coupled.

The rotating body 200 is rotatably coupled to both ends of the handle bar 100 about the longitudinal center axis 121 of the handle bar 100. [ The rotating body 200 may be formed as a hollow cylindrical drum as shown in FIG. 2, but may be formed in a simple flat plate shape or the like.

The operation cable 400 is wound around the rotating body 200 in a state where one end of the operation cable 400 is coupled to the rotating body 200 and a separate hook 410 is formed at the other end of the operation cable 400, So that it can be fixed by hooking the hooking ring 410. When the rotating body 200 is formed in a drum shape, the operating cable 400 can be wound around the outer peripheral surface of the rotating body 200. The operation cable 400 is configured to rotate in one direction as the other end of the operation cable 400 is pulled so as to be unwound from the rotation body 200. When the rotation body 200 is rotated in the opposite direction And is configured to be wound on the rotating body 200 when rotated.

The elastic member 300 is installed to apply an elastic rotation restoring force to the rotating body 200 when the rotating body 200 rotates. For example, the elastic member 300 may be applied in the form of a spiral spring. 3, the center portion of the spiral spring is coupled to the center shaft 121 of the handle bar 100, and the outer end of the spiral spring is coupled to one side of the inner circumferential surface of the rotary body 200. [

1 and 2, a cover housing 500, which can cover the outer space of the rotating body 200, is coupled to both ends of the handle bar 100, and at one side of the cover housing 500, A cable through hole 510 may be formed so that the cable 400 can penetrate.

According to the above-described structure, the weight lifting mechanism according to the embodiment of the present invention grasps the handle bar 100 in a state where the user fixes the engagement ring 410 of the operation cable 400 on a foot or a separate fixing mechanism or the like The operation cable 400 is pulled or released, and the rotating body 200 is rotated. In this process, the elastic member 300 rotates Since the elastic rotation restoring force acts on the body 200, a motion load is generated in the process of bending or stretching the arm.

5, when the operation cable 400 is pulled to fix the hooking ring 410 on the user's foot and the handle bar 100 is held in the hand and the arm is bent in this state, The operation cable 400 is moved downward from the cover housing 500 of the handle bar 100 so as to move relative to the operation cable 400 when the handle 100 is moved upward. Accordingly, since the operating cable 400 is pulled, the rotating body 200 is rotated in one direction.

At this time, since the elastic rotation restoring force is applied by the elastic member 300 during the rotation of the rotating body 200, the elastic rotation restoring force acts as a dynamic load. Therefore, when the user grasps the pull rod 100, Is performed in such a manner that it is resistant to the dynamic load due to the elastic rotation restoring force.

That is, a general dumbbell exercises a weight movement by using a dynamic weight due to the weight of the weight, but the weight exerciser according to an embodiment of the present invention exercises a weight using a dynamic load due to the elastic rotation restoring force.

In this case, if the force is not applied at all during the process of stretching the arm, the handle bar 100 moves downward rapidly due to the elastic rotation restoring force. Therefore, In the course of expanding the arms, it is also possible to increase the exercise effect by applying a certain amount of force so that the arms can be slowly opened.

This is similar to a general dumbbell movement process, so that the user can easily perform it without difficulty. In other words, even in a general dumbbell exercise, since the downward load due to the weight of the dumbbell is applied in the operation of extending the arm, the exercise state is continuously maintained by applying a certain amount of force and slowly spreading the arm. The weight exercising apparatus according to the present invention also applies a certain amount of force against the elastic rotation restoring force during the stretching of the arm so that the arm is slowly stretched so that the exercise condition can be maintained and the exercise process can be conveniently performed in the same manner as a general dumbbell Can be performed.

3, the elastic member 300 may be formed in the form of a spiral spring. In this case, when the operation cable 400 is connected to the rotating body 200, The rotation body 200 rotates in the counterclockwise direction with reference to the direction shown in FIG. 3, whereby the elastic rotation restoring force of the spiral spring acts to return the rotation body 200 to the original state Elastic rotation force is generated. Accordingly, when the pulling force on the operation cable 400 is released, the rotating body 200 is rotated in the direction of returning to the original state by the elastic rotation restoring force, and the operating cable 400 is wound on the rotating body 200 again .

According to this configuration, the weight exercising apparatus according to an embodiment of the present invention is configured to be able to perform a weight exercise using a dynamic load due to an elastic force, unlike a dumbbell having a separate weight, It can be made of resin material. It is light, easy to handle, easy to carry, and easy to carry and carry, making it possible to exercise weight anytime and anywhere more conveniently.

In addition, the dynamic load due to the elastic restoring force can be variously set according to the elastic strength of the elastic member 300, and the weight lifting mechanism having various elastic restoring forces can be variously manufactured and used in the same shape and size.

2, a weight movement mechanism according to an embodiment of the present invention includes a rotation detection sensor module 600 capable of sensing the rotation of the rotation body 200, And a control unit 700 for receiving the sensed value and calculating the number of pulls of the operation cable 400. Each time the user performs the operation of folding and stretching the arm while holding the handle bar 100 in the hand with the engagement ring 410 of the operation cable 400 being fixed, the operation cable 400 is pulled once The number of times of pulling the operation cable 400 once means that the user has performed the operation of folding and unfolding the arm once. Therefore, the number of traction on the operation cable 400 means the number of times the user exercises the weight.

The control unit 700 may transmit the count information of the operated cable 400 to an external terminal (not shown) such as a smart phone through a separate communication unit 720, and at the same time or separately, (750).

2, the handle bar 100 is detachably attached to the body member 110 and the central shaft member 120. A receiving space is formed in the body member 110, The control unit 700 may be installed in the inner space of the member 110 and the display unit 750 may be externally exposed to the outer surface of the body member 110. [ A PCB 710 is embedded in the inner space of the body member 110 and a battery 730, a control unit (control chip) 700, a communication unit 720, and the like are mounted on the PCB substrate 710 . Further, an operation unit such as a power button 740 may be formed on the outer surface of the body member 110.

According to such a configuration, information such as a user's number of times of weight exercise or time can be output through the display unit 750 or transmitted to a separate external terminal so that the user can instantly recognize his or her own exercise record, And make exercise planning management more systematic and efficient.

2 and 4, the rotation sensor module 600 includes a recognition mark 610 mounted on the rotation body 200 and rotated together with the rotation body 200, a recognition mark 610 And a plurality of detection sensors 620 mounted on the handle bar 100 along the circumferential direction so as to be sequentially sensed. The detection sensor 620 may be composed of various sensors such as an optical sensor and a hall sensor and the recognition mark 610 may be formed as recognition means capable of quickly detecting the detection sensor 620 corresponding to the sensor of the corresponding type . For example, a light reflector, a magnet, or the like can be applied.

As shown in FIG. 4, the recognition mark 610 is coupled to one side of the rotary body 200 and rotates integrally with the rotary body 200, And the plurality of detection sensors 620 detect the recognition mark 610 in such a manner that the first detection sensor 621, the second detection sensor 622 and the third detection sensor 623 are arranged in the counterclockwise direction Respectively. 4A, when the rotation body 200 rotates in the counterclockwise direction, the plurality of detection sensors 620 detect the movement of the first detection sensor 621 according to the rotation direction of the rotation body 200, The second sensing sensor 622 and the third sensing sensor 623 sequentially sense the recognition mark 610. [ On the contrary, when the rotating body 200 rotates in the clockwise direction as shown in FIG. 4 (b), the third sensing sensor 623, the second sensing sensor 622, and the first sensing sensor 621 The recognition mark 610 is detected in order.

Accordingly, the controller 700 can determine the rotational direction of the rotating body 200 through the sensing sequence of the recognition mark 610 by the plurality of the sensing sensors 620. For example, when the recognition mark 610 is detected in the order of the first detection sensor 621, the second detection sensor 622, and the third detection sensor 623, When the recognition mark 610 is detected in the order of the third detection sensor 623, the second detection sensor 622 and the first detection sensor 621, the rotation direction of the rotation body 200 is Clockwise direction.

In this way, the control unit 700 can determine the direction of rotation of the rotating body 200, and calculate the number of pulls of the operation cable 400 through the detection of the rotation direction change.

For example, when the user grasps the handle bar 100 and bends and stretches the arm once, the rotating body 200 is rotated in the counterclockwise direction by pulling the operating cable 400 in the course of bending the arm , The rotating body 200 is elastically rotated and restored and rotated in the clockwise direction in the course of expanding the arm. Of course, here, the rotational direction of the rotating body 200 may be counterclockwise -> counterclockwise but not counterclockwise -> counterclockwise.

In this operation, the controller 700 calculates a value sensed by the rotation sensor module 600, and determines that the rotary body 200 has rotated counterclockwise and then rotated clockwise .

At this time, each time the rotation direction of the rotating body 200 is changed, the control unit 700 can calculate the number of pulls of the operation cable 400 once. That is, when the rotation direction of the rotating body 200 is changed from the counterclockwise direction to the clockwise direction, it can be determined that the operation cable 400 is once pulled. The one-time pulling of the operating cable 400 means that the user holds the pull rod 100 and folds and folds the arm once, as described above.

The control unit 700 may output the number of traction of the operation cable 400 calculated in this manner to the display unit 750 or transmit it to the external terminal so that the user can immediately recognize the exercise information.

When it is determined that the operation cable 400 has been pulled once every time the rotation direction of the rotating body 200 is changed, the user does not normally perform the folding and straightening operation of the arm, The rotation direction of the rotating body 200 is changed even when the arm is folded, so that it is also determined that the rotating body 200 has been pulled once. In this case, since it is not a normal weight movement operation, it is preferable not to judge that it has been pulled once.

Accordingly, in accordance with an embodiment of the present invention, the control unit 700 controls the rotational speed of the rotating body 200, which is sensed for each interval in which the rotating body 200 indicates the same rotational direction, It can be determined that the operation cable 400 has been pulled once. The number of revolutions of the rotating body 200 can be determined by determining how many times the recognition mark 610 is sensed for each section determined to be rotated in the same direction through the sensing sensor 620.

That is, when the user holds the handle bar 100 and folds the arm once and then completes the operation normally, the operation cable 400 is formed to have the same working length in the process of folding the arm and extending the arm, The rotational speed of the rotating body 200 is formed to be equal to each other during the forward and backward times based on a time point when the rotational direction of the rotating body 200 is switched. For example, if it is detected that the rotary body 200 is rotated three times in the counterclockwise direction during the folding process of the arms, in the course of expanding the arms, it is determined that the rotary body 200 is rotated three times in the clockwise direction do. However, if the weight motion of the user is performed incorrectly and incompletely and precisely, the number of revolutions of the rotating body 200 may be changed by changing the operation length of the arm during the folding process and the arm extension process. That is, it is detected that the rotating body 200 is rotated three times in the clockwise direction in the course of expanding the arm, but it can be detected that the rotating body 200 is rotated twice in the counterclockwise direction during the folding of the arm.

Therefore, the number of revolutions of the rotating body 200 is determined by intervals of intervals in which the rotating direction of the rotating body 200 appears in the same direction through the sensing signal of the sensing sensor 620, It can be determined that the operating cable 400 has been pulled once and can be outputted to the display unit 750 only when it is detected that the number of revolutions of the rotating body 200 is the same for every section appearing in the same direction.

By determining the number of weight exercises only when the weight movement operation of the user is correct according to the operating frequency calculation method of the operating cable 400, it is possible to maximize the exercise effect by inducing the correct exercise operation to the user.
