Typically, most of these exercises are mostly musical instruments for lifting or pulling a running machine or weight, or for stretching the body.

These exercise devices have a sufficient exercise effect if they exercise consistently, but they can be mostly hard and boring exercise devices, and tend to quit without continuing the continuous exercise. The main reason for not continuing the exercise in this way is that there are many cases of quitting due to the lack of interest in exercise.

On the other hand, there is boxing as one of the items that can feel pleasure without boredom among kinds of exercise. Boxing is a movement that can maximize the whole body movement in a short period of time.

However, boxing is a sport in which the opponent must be present in its nature, and there are limitations in enjoying it as a general fitness equipment because there is a place and a financial problem in which a professional boxing stamp must learn money.

Of course, there was a sandbox or punching ball hanging on the trees or in the park in the past, which can be fun for a moment, but there is no way to stimulate the ongoing exercise. It is an exercise apparatus that has lost interest as easily as a general exercise apparatus. Therefore, if such exercise apparatuses are used, it can be a great help to make continuous exercise if it can induce the interest of the exercise person like play.

On the other hand, although it was not an athletic apparatus, there was a punching machine as an athletic-related entertainment apparatus which was popular explosively. The reason why the punching machine was so popular was that the punching power of the player can be confirmed in real time, And sporting factors.

However, the entertainment apparatus such as the punching machine has a limitation that a small amount of coins must be inserted for operation and that the electric power must be connected only in a place where there is no danger of electric shock in order to operate, It is a systematic problem that it can not be used as a universal exercise equipment due to the limitation of an entertainment apparatus aimed at a limited demand group that can not be enjoyed by all because it is not a device considering conditions and is set to a general youth or an adult male.

Therefore, it is possible to utilize it as a living athletic exercise apparatus which can be enjoyed by various persons including athletic facilities, and there is a need for a fitness apparatus having a great exercise effect in a short period of time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 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 diagram showing a main configuration of a boxing play apparatus according to the present invention. FIG. 2 is a partial cut-out view showing a main configuration of a boxing play apparatus according to the present invention. FIG. 4 is a front view of a front view showing the left guide and the right guide of the boxing play apparatus of the present invention. FIG.

 As shown in the figure, the present invention comprises a vertical plate 11, an upper plate 12 projecting forward from the upper portion of the vertical plate, and a lower plate 13 projecting forward from a lower portion of the vertical plate, And a guide pipe (14) extending perpendicularly to the front and rear sides of the main body (1). Here, the guide tube 14 is exemplarily provided in the form of a circular tube, but the cross section may be formed of a polygonal shape or may have a circular cross section including an ellipse instead of a cross section of a circle.

At this time, in order to protect the main body from bad weather such as snow blindness, the roof plate 15 may be further installed so as to be spaced toward the upper side of the top plate 12. [ This makes it possible to protect the punch force measuring unit 4, which will be described later, provided between the top plate and the roof plate, thereby enhancing durability.

Further, a cover 16 may be provided on the front portion between the upper plate and the lower plate to prevent exposure of the impact transmission gear portion described later.

The striking portion 2 is provided with a tube 21 inserted into the guide tube 14 of the main body 1 and a front portion of the tube 21 And an elastic force is applied to the striking plate when the tube is retracted into the guide tube due to the force applied to the striking plate by the force applied to the striking plate around the tube 21 and the guide tube 14 A coil spring 23 for restricting the position of the striking plate while providing a shock to the striking plate, and a coil spring 23 installed on both sides of the striking plate for shrinking by a biasing force or being buffered by a coil spring, And left and right guide portions 24a and 24b for guiding stably. Here, the tube 21 is provided as a circular tube as an example in the drawing, but the tube may have a polygonal cross-section or may have a circular cross-section including an oval instead of a cross section.

By inserting the pin-shaped stopper 25 into the hole 211 formed at the rear portion of the pipe 21 or at various points in the longitudinal direction thereof, the pipe is pushed to the rear portion by the normal force or the striking force, The rear end length of the pipe is restrained from entering the guide pipe (14) by a predetermined length or more. At this time, the coil spring is maintained in a contracted state rather than the usual length, so that the striking plate always maintains the state having a buffering force. And, the coil spring is set up in consideration of the contraction force state so that the shrinkage force does not generally cause the most shrinkage in order to increase the discriminating power when measuring the impact force of the exerciser.

In addition, when the hitting force of the exerciser is not general, in order to control the contraction force, when the hinge is inserted into a plurality of holes formed in the longitudinal direction, when the hinge is inserted inward at the insertion position, an additional shrinking force is applied to the coil spring, do.

The basic shape of the left guide part 24a and the right guide part 24b may be a plate-like shape (see Fig. 4 (a)) or a circular tube shape (see Fig. 4 . In the case of a circular tube, a circular groove (not shown) is drilled in the vertical plate to move the tube 21 forward and backward As shown in FIG.

In addition, the striking plate 22 is configured to protect the cushion pad 221 on the front surface to protect the user's hand. The cushion pad is configured to be detachably attached to the impact plate by a known method such as a Velcro tape or a screw-fastening type so that the cushion pad can be replaced at the time of breakage. When the cushion pad 221 is in good condition, the impact on the wrists, elbows, shoulders, and waists is prevented so that continuous movement is possible.

The horizontal direction kinetic energy corresponding to the punching force of the exerciser applied to the striking portion 2 is transmitted to the punching force measuring device 4 by the striking force transmission gear portion 3. [ The hitting force transmission gear unit 3 includes a raising gear 31 provided along the left guide unit and a first rotating shaft 33 rotated in one direction only when the punching force is applied in contact with the railing gear, And a ratchet gear 32 that does not rotate one rotation shaft. That is, the ratcheting gear is configured to rotate only when the lever is pushed backward by the force applied to the striking plate.

The first rotary shaft 33 is installed to rotate through the lower plate and the upper plate.

A gear (34) is axially coupled to the upper end of the first rotary shaft passing through the upper plate to transmit a rotational force to the punch force measuring device (4). At this time, bearings (35a, 35b) are provided at the portions through which the first rotary shaft of the lower plate and the upper plate penetrate, so that the first rotary shaft (33) can be supported while being smoothly rotated without noise.

The rotation amount by which the gear 34 of the striking transmission gear unit 3 rotates is transmitted to the punch force measuring unit 4 in contact therewith, and a coefficient according to the individual punching force of the exerciser is displayed. A second rotating shaft 42 which is installed through the upper plate so as to be axially coupled with the punch force measuring gear and is supported by a bearing (not shown), and a punching force measuring gear 41 And a measuring plate 43 which is axially coupled to the second rotary shaft at the upper portion of the measuring gear and interlocked.

Meanwhile, when the punch force measuring gear 41 and the measuring plate 43 receive the hitting force and maintain the rotated state, if it is necessary to know the amount of the hitting at the time of the hitting again, the punch force measuring gear 41 and the measuring plate 43 are manually rotated in the reverse direction, Is reset to '0' or 'reference time', the punching force of the exerciser can be measured again when the punching force is applied again. At this time, even if the punch force measuring gear 41 and the measuring plate 43 rotate to rotate the gear 34 of the impact transmission gear portion 3 to rotate the first rotating shaft 33 interlocked with the gear 34, And the left guide portion 24a is not moved in the horizontal direction. The reason is that the ratchet gear 32 connected to the rack gear does not rotate in the reverse rotation direction. If a general gear is used without using a ratcheting gear rotating only in one direction, it is impossible to measure the punching force of the punching force measuring gear 41 and the measuring plate 43, and initialization is impossible. That is, when the striking plate is retracted, the lattice moves together with the coil spring, and when the position of the striking plate is restored, the measuring plate indicating the punching force is re-initialized and the punching force can not be known.

If the punch force is not known, the measuring plate may be allowed to rotate in one direction each time it is struck without manually rotating it in reverse. In such a case, it is a case of continuous batting exercise.

The support body 5 is installed to have a predetermined height from the ground according to the body conditions of the exerciser. At this time, the support portion may be configured as various embodiments as shown in FIGS. Hereinafter, each embodiment will be described.

FIG. 5 is a view showing an example of a fixed boxing play apparatus according to an embodiment of the present invention, FIG. 6 is a view showing an example of a box-and-drop type boxing play apparatus according to another embodiment of the present invention, FIG. 7 is an illustration showing a rotary type boxing play apparatus according to another embodiment.

First, the support portion shown in Fig. 5 is a support portion 5 configured in a fixed manner. In the case of such a stationary support unit, when a plurality of supporting members differing in height from each other according to a height difference between male and female, and a plurality of boxing play apparatuses are installed by combining the respective supporting members and the main body, .

As shown in the figure, the stationary support unit comprises a support base 51 for fixing both sides of the vertical base plate, which supports the support base 51 or the support base 51 bent downward from the upper portion of the vertical plate, And a concrete or metal fastener 52 which is fixedly supported by using a usual fixing method such as welding or bolt screw connection and is formed at a lower portion of each support and fixed on the ground. And a concrete or metal fixture 52 fixed to the ground by being positioned at a lower portion thereof.

The support portion shown in Fig. 6 is a support portion 5 configured by a vertical lift type. In the case of the above-mentioned lifting and lowering support part, when the supporting part and the main body are combined to provide a boxing play device, the height of the support part can be changed to a height suitable for the physical conditions of the person,

Such a lifting and lowering support portion includes a guide pipe 53 vertically fixed to both sides of the vertical base plate 11 by a common method including welding, bolt and nut tightening, etc., A horizontal support 54 connecting the both side supports 51 in the horizontal direction and a lower support plate 54 connected to the lower support plate 51 in the horizontal direction, 13, a shaft 56 provided horizontally on the horizontal support so as to vertically raise and lower the height adjustment shaft, and a shaft 56, which is axially coupled to the shaft, And a rotary gear 57. When the rotary gear is rotated by changing the rotation direction to a desired height by using the knob 58 and then fixed by using the fixing device 59, the rotation of the rotary gear is stopped at the corresponding height so as to be fixed according to the physical condition of the exerciser do. The fixing device may be any of ordinary rotary gear fixing methods. For example, a stopper may be provided on the horizontal support so as to be interposed between the rotary gears so that the rotation can be interrupted. Without such anchoring device, the weight of the body spontaneously rotates and the position is not fixed.

The support portion shown in Fig. 7 is a rotatably supported portion 5. In the case of such a rotary support unit, the rotary support unit 51a can rotate the support unit fixed to the lower plate of the body, and when the boxing play unit is installed, anyone who is younger or younger can rotate the rotary support unit to a height suitable for her / You can do a boxing exercise at the play equipment. When the rotary support rotates, the body rotates together.

As shown in the figure, the rotary support includes a rotary support 51a disposed under the lower plate of the main body and a concrete or steel material fixed to the ground at a lower portion thereof. The rotary support includes a plurality of stepped portions having different heights And a multi-stage fixing table 52a composed of a pair of foot plates. The rotary support 51a may include a bearing and may be easily rotated when installed on the multi-stage fixing table 52a.

For example, if the individual stages having different heights from the ground constituting the multi-stage fixing table 52a are displayed, for example, 130cm, 140cm, 150cm, or 160cm, if an athlete is lifted on the scaffold of the stage corresponding to the key of the corresponding size, When the athlete stretches his arm, it becomes a proper height. In other words, the height of the step marked 130cm becomes the highest step rising from the ground.

At this time, a rotation interrupter 521 is installed between the multi-stage fixing table and the rotation supporting table, and the rotation supporting table 51a is rotated so that the rotation supporting table 51a is rotated according to its position. When the rotation is interrupted in this way, a person who intends to exercise can use the boxing device stably. As shown in the figure, the shape of the rotary interrupter may include at least four holes corresponding to the stepwise rotation position on the rotary support, and a method of inserting and fixing the stopper (hook) formed in the multi- Lt; / RTI > The stopper can use a horizontal sliding method or a rotating method. Of course, there are numerous manual locking devices, such as a conventional door lock system, a ball stopper system, a slide type lock lock system, and the like, which can control not only the above-described type but also rotational movement.

The operation of the thus configured boxing play apparatus of the present invention will be described below.

When the exerciser who intends to perform the boxing exercise price the cushion pad 221 provided on the striking plate 22 of the striking part 2, the striking plate 22 supported by the coil spring 23 is contracted in accordance with the magnitude of the punching force , The tube 21 inserted into the guide tube 14 of the main body 1 is pushed backward as much as it is contracted. When the tube is pushed in this manner, the force is transmitted to the punch force measuring unit 4 through the impact force transmission gear unit 3 by the horizontal direction kinetic energy corresponding to the punch force of the exerciser applied to the hitting unit 2. [ That is, the ratchet teeth 31 provided along the left guide portion 24a of the striking portion 2 are retracted while the ratchet gear 32 engaged with the ratchet teeth is rotated in one direction, The rotation of the gear 34 is controlled by rotating the punching force measuring gear 41 of the punching force measuring device 4 which is in gear engagement with the gear 34 and rotating the punching force measuring gear 41 with the punching force The position of the measuring gear 43 on the upper part of the measuring gear 41 rotates to show the displayed number to the exerciser.

At this time, the striking plate 22 is restored to its original position by the elasticity of the coil spring after the striking. Even if the position of the striking plate is restored to its original position, the measuring plate 43 does not rotate in the opposite direction, Information will be maintained. This is because the ratchet gear 32 and the first rotary shaft 33 rotate only in one direction and rotate, whereas in the opposite direction, the ratchet gear 32 does not rotate in the reverse direction, The ratcheting gear 32 does not rotate when the knee fishing gear 31 provided along the left guide portion 24a of the left knee gear 2 moves back after moving along the striking force. Because of this principle, the check gear 43 is not rotated even when the measuring plate 43 is reversely rotated at the time of reset after rotation by the hitting force.

If you perform a continuous striking motion without striking force, the mark on the measuring plate can be steadily struck with a fixed striking motion.

In addition, according to the embodiment of FIG. 5, when an athlete wishes to exercise according to his or her own key, he or she may go to a boxing device corresponding to his / her key among several boxing devices.

In the boxing device according to the embodiment of FIG. 6, the rotary gear 57 is rotated to move up and down the height adjustment lever 55 to position the body at a position corresponding to the body condition of the user, To fix the rotary gear 57 and then move it.

In the boxing apparatus according to the embodiment of FIG. 7, the rotation support 51a may be rotated to move to the footrest height of the multi-stage support table 52a corresponding to the user's own key, and then move.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
