Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the whole-body exercise progressive bicycle 1 according to the present invention has a squat exercise, a front press exercise, a push in addition to a general bicycle capable of moving forward using a pedal 5. ) You can do exercise and pull exercise together.

First driving part

The whole body movement progressive bicycle 1 according to the present invention has wheels 12a and 12b rotatably mounted to the front and rear of the frame 10, as shown in FIG. Such wheels 12a and 12b, when the forward movement is made by the bicycle pedal 5, the front wheel 12a has a steering function, the rear wheel 12b has a propulsion function.

In addition, the present invention has a first drive unit 20 to impart rotational force to the rear wheel 12b by using the pedal 5. The first drive unit 20 is to provide the driving force of the bicycle to the rear wheel (12b), is mounted to be rotatable through the pedal (5) in the center of the frame 10 to drive the rear wheel (12b). A first drive sprocket 24 for rotating the chain 22.

This first drive sprocket 24 includes a first drive sprocket 24 for use as a general bicycle, as shown in FIG. 2, which transmits power to the rear wheels 12b via the chain 22. Is connected as possible. On the other hand, the sprocket 27 of the rear wheel 12b rotates in the forward direction during the forward rotation (clockwise rotation) of the pedal 5, but has a one-way ratchet for idling during the reverse rotation (counterclockwise rotation). Equipped. Thus, the first drive unit 20 is always configured to move the bicycle forward when the first drive sprocket 24 is rotated clockwise through the pedal 5.

The first drive unit 20 is rotated by integrally connecting the driven sprocket 32 for the whole body movement associated with the second drive unit 40 to the rotation shaft 20a, the rotational force from the second drive unit 40 Is added to the first drive sprocket 24 to achieve rotation of the rear wheel 12b.

That is, the first drive unit 20 has side sprockets 32 and 33 associated with the second drive unit 40 mounted side by side in the side of the first drive sprocket 24 and the center of the first drive sprocket 24. Is connected to the rotating shaft 20a. Therefore, when the driven sprocket 32 for the whole body movement rotates in the forward direction (clockwise) by the operation of the second drive unit 40 to be described later, it rotates the rotation shaft 20a of the first drive sprocket 24 in the same direction. It is possible to rotate the rear wheel 12b through the chain 22 of the first drive unit 20 to proceed the bicycle. By the function of the second driving unit, the bicycle can obtain additional driving force than when the driving force is obtained only by the first driving unit and can increase the speed of the bicycle.

Meanwhile, in addition to the driven sprocket 32 for the whole body movement, the general driving driven sprocket 33 is additionally arranged in the first driving unit 20 of FIG. 2. The general driving driven sprocket 33 is used when the bicycle is in a general driving mode, that is, in a driving mode in which the driving force of the first driving unit itself is not transmitted without receiving the driving force of the second driving unit due to the whole body movement. The chain connected to the second drive unit 40 is connected to the normal drive driven sprocket 33 in the case of the normal drive mode, and connected to the driven sprocket 32 for the whole body movement in the case of the whole body movement progressive mode. The general drive driven sprocket 33 is used when the second drive unit is not used. When the first drive sprocket rotates in the clockwise direction, the driven sprocket 33 rotates with the ratchet to which the outside of the second drive sprocket is provided. The rotary gear 42 is idling so as not to affect the rotary gear 42 by the 44a, and when the user wants to idle the first driving sprocket counterclockwise, idling is provided by the ratchet provided in the general driving driven sprocket 33. Allow it. This is to give the same function of the general bicycle that can idle the pedal (5) according to the user's convenience when using the present invention as a general bicycle, for this purpose, the one-way ratchet is formed on the driven sprocket 33 for general driving The gear shifting structure between the general sprocket for driving and the whole body movement can be used by arbitrarily selecting the gear and the gear shifting structure of the general bicycle.

Second driving part

The present invention includes a second drive unit 40 on the front side of the frame 10, such a second drive unit 40 is the first drive unit through the forward and backward swing operation of the handle 60 of the bicycle front side ( A rotational force may be added to 20 and through this, a rotational force may be applied to the rear wheel 12b.

As shown in FIG. 3A, the second driving unit 40 includes a rotary gear 42 rotatably mounted on one front side of the frame 10 and a second drive coaxially connected to the rotary gear 42. It includes a sprocket 44, the second drive sprocket 44 is a structure that is connected through the chain 46 to be rotatable to the driven sprockets (32, 33) of the first drive unit (20).

In addition, the rotary gear 42 is gear-coupled to the inside of the arc gear 48 which rotates at a predetermined angle in parallel with the forward and backward swing motion of the front handle 60, and inside the arc gear 48. The left gear 48c, which is also formed in an arc shape, is provided on both left and right sides so that the rotary gear 42 rotates in a clockwise direction when the arc gear 48 is turned clockwise. There is a right gear 48d which causes the rotary gear 42 to rotate clockwise when the gear 48 is turned down counterclockwise, which is a function of pushing (squat, press, push) and pulling (pulling), respectively. Used to grant a function. For example, when explaining the pushing motion (squats, presses, pushes), the rotary gear 42 is bitten by the left gear 48c, and the rotary gear 42 also clockwise when the arc gear 48 is turned clockwise. Rotation gear is rotated in the clockwise direction so that the outer side of the second drive sprocket is also rotated clockwise to apply driving force to the driven sprocket 32 for the whole body movement, and when the arc gear 48 is turned counterclockwise Since 42 is also rotated counterclockwise, it is idle by the one-way ratchet 44a provided in the second drive sprocket, so that no force is transmitted to the driven sprocket 32 for the whole body movement, so that only the driving force for the forward travel is achieved. This is to be provided.

On the contrary, in the case of the pulling motion (pull), since the rotary gear 42 is bitten by the right tooth 48d, the driving force for the forward movement is applied only when the arc gear 48 is turned down counterclockwise.

As mentioned above, the second drive unit 40 transmits the driving force according to the clockwise rotation of the rotary gear 42 to the inside of the second drive sprocket 44 so that the second drive sprocket 44 is the above-mentioned. It is configured to contain a one-way ratchet (44a) to be rotatable in the same direction as the rotary gear 42, and to rotate the counterclockwise rotation of the rotary gear 42 without transmitting. Only the clockwise rotation of the second drive sprocket 44 is allowed.

As shown in the side view in FIG. 3A, the second drive unit 40 has the rotary gear 42 rotated by the arc gear 48, and the arc gear 48 has a front end of the front handle 60. ) Is connected through a square head hinge shaft (48a) of the rotary rod 62 is switched to the upper and lower arc-shaped motion by the forward and backward swing motion of the front handle (60) to operate the rotary gear (42). The circular head hinge shaft 48b of the rotating rod 62 has a function of rotatably connecting the front handle 60 portion to the frame.

That is, the arc gear 48 has arc-shaped left and right gear portions 48c and 48d to which the rotary gear 42 is geared from the inside, and as mentioned above, such a left and right gear portion 48c. , 48d operates the rotary gear 42 via the gear of the rotary gear 42 at the time of vertical rotation of the arc-shaped gear 48.

In addition, the rotation of the rotary gear 42 transmits the rotational force to the second drive sprocket 44 connected coaxially to rotate the second drive sprocket 44, the second drive sprocket 44 is a chain 46 Through this is to transmit the rotational force to the driven sprocket 32 for the whole body movement located on the first drive unit 20 side.

In this process, the rotary gear 42 is rotated forward and backward by the arc-shaped gear 48, but such a reverse rotation of the rotary gear 42 is in the one-way ratchet 44a built in the second drive sprocket 44 As a result, the reverse rotation is not transmitted, only the forward rotation is transmitted to rotate the second drive sprocket 44. Here, the forward rotation means clockwise and the reverse rotation means counterclockwise.

One-way ratchet 44a is formed in the same manner as in FIG. 3B. That is, when the rotary gear 42 rotates in the clockwise direction by the movement of the handle, the second drive sprocket 44 is also formed to rotate in the clockwise direction. On the other hand, the rotational force according to the rotation of the pedal of the first drive unit 20 rotates the chain 46 connected to the second drive unit 40, where the chain 46 drives the second drive. The sprocket 44 is rotated clockwise. When the second drive sprocket 44 rotates in the clockwise direction, the rotary gear 42 does not rotate by the one-way ratchet 44a. (FIG. 3b (b)) The reason for this configuration is that the bicycle is operated through the whole body movement. In order to obtain additional driving by transmitting the driving force of the second driving unit to the first driving unit only when advancing, on the contrary, when there is no whole body movement due to the handle even in the case of general exercise or whole body operation, the first driving unit The driving force of is to be transmitted to the second drive unit to prevent the unwanted movement of the handle occurs.

In addition, the chain tension adjusting unit 49 is formed in the frame 10 so as to be operable while being connected to the chain 46, the rotary gear 42 along the rotary gear movement groove 55 in the direction of the arrow of Figure 3a. Functions to adjust the tension of the chain as the position moves. In this way, the rotary gear 42 is installed to be movable in the direction of the arrow in the frame 10, the movement of the rotary gear 42 can be made by taking the same form as the gear shift in the handle, and also maintain the moved state A clasp (not shown) can be applied to The rotation of the rotary gear 42 to the left gear 48c or the right gear 48d may be performed by using the front handle 60 to push or lift (left tooth 48c bite), or pull motion. This is done only when the user selects the right gear (48d bit).

On the other hand, the arc-shaped gear 48 forms a pin locker 52 penetrating to the frame 10 side on one side thereof so that pins (not shown) are fixed to the front and rear of the front handle 60. It also has a structure that restrains the true swing motion. In such a structure, when the forward and backward swing motion of the front handle 60 is unnecessary, when the pin is inserted into the pin holder 52, the rotation operation of the arc gear 48 is stopped, resulting in the arc gear 48. The forward and backward swing motions of the connected front handle 60 are also stopped, and thus, when fixed in this way, the front handle 60 is a case of a general bicycle which cannot perform forward and backward swing motions.

Steering and Whole Body Exercise

As shown in FIGS. 1 and 4 as a whole, the front wheels 12a are rotatably mounted to the steering frame 66. The steering frame 66 is coupled to rotate together with the rotation of the rotation frame 63 to perform a steering function. A ball bearing 64 and a rotation rod 62 are mounted inside the rotation frame 63. The rotating rod 62 is connected to the main frame 10 of the bicycle through a circular head hinge shaft 48b, the rotating frame 63 outside the rotating rod 62 is connected to the telescopic portion 70 of the rectangular cross section. .

As shown in FIGS. 4 and 5A, the rotating rod 62 has a circular spherical bearing (not shown) on the frame 10 side through a circular head hinge shaft 48b at the lower end of the frame 10. In conjunction with the front and rear handles 60 and the forward and backward swing operation for the frame 10 is possible. In addition, the rotating rod 62 is mounted so that the rotating frame 63 is rotatable through the ball bearing 64 to the outside thereof so that the rotating rod 62 can be rotated (ie, steered) in a horizontal direction on a plane about the rotating rod 62. , This structure enables the steering operation of the bicycle by rotating the front wheel 12a at the bottom of the steering frame 66 left and right.

In addition, the square head hinge shaft (48a) of the rotating rod 62 is formed with a square head for connecting the front end of the arc-shaped gear 48 is also connected to the arc-shaped gear 48, the forward and backward swing operation of the front handle (60) At the time, the upper and lower arc motion of the arc gear 48 is configured to be made at the same time.

Thus, the present invention enables the squat, press, push, pull movement in addition to the bicycle pedal (5) movement through the forward and backward swing operation of the front handle 60, the arc-shaped gear 48 and the rotary gear 42 Through this, the rotational force obtained by the second driving unit 40 is transmitted to the first driving unit 20 side, and the moving speed of the bicycle is added through the rear wheel 12b. Look at the squat, press, push, pull motion of the front handle below.

Telescopic portion 70 is formed on the upper side of the front handle 60. This telescopic portion 70, as shown in Figure 5b, including a multi-stage folding structure of the four-sided section to enable squat, press, push, pull movement in addition to the bicycle pedal (5) movement.

That is, if the front handle 60 is pushed up to the upper side, due to the structure of the telescopic portion 70 folded in a multi-stage, it is extended to the upper side, and if the front handle 60 is pushed down to the lower side, the length of the telescopic portion 70 overlaps again Is shortened structure. Through this structure, the present invention enables squat, press, push, and pull motion using the front handle 60. The telescopic portion 70 forms an appropriate internal gap so as to perform a damper function on its own so that the state of the telescopic portion 70 can be maintained even to some extent. In addition, the telescopic portion 70 is configured so that the length is adjusted to match the angle when the angle of the handle and the user, the frame of the bicycle is changed when the handle is lowered to the user side. The movement of the handle using this telescopic portion will be described later.

On the other hand, the telescopic portion 70 is formed of a polygonal cross section, preferably a rectangular cross section, not circular, so as to transmit a steering force of the handle to perform a steering function. The rotational force of the handle is transmitted to the rotation frame 63 so that the steering frame 66 can rotate in accordance with the rotation of the rotation frame, thereby performing a steering function. On the other hand, the steering frame 66 is capable of steering in a range that does not interfere with the arc-shaped gear 48 and the frame 10 connected to the hinge shaft (48a, 48b). In order to prevent interference due to contact with the arc-shaped gear 48 and the frame 10, a key structure for limiting the rotation angle may be formed between the rotating rod 62 and the rotating frame 63. (Not shown)

Saddle etc

In addition, the present invention includes a foldable saddle 80 as shown in Figure 6a toward the central upper side of the frame 10, the saddle 80 is a plurality of supports (82a) connected to each of the frame 10 is rotatable bottom ), 82b. Among the plurality of supports 82a and 82b, the saddle 80 is fixed to the upper end of the one support 82a, and the upper end of the other support 82b is inserted to the inner side to form a hook groove 86 to be fixed. . Therefore, when the other support 82b is separated from the hook groove 86, the plurality of supports 82a and 82b are located along the saddle lowering groove 87 formed in one support 82a due to the rotational structure of the lower end thereof. The support 82b can be folded down and folded toward the center side of the frame 10. When the plurality of supports 82a and 82b are raised, the upper end of the other support 82b is inserted into the hook groove 86. The supports 82a and 82b are fixed so that the saddle 80 is located on the upper side and can sit thereon as shown in FIG.

Such saddle 80 is to be stored in the frame 10 side, if you want to use the footrest 90 to be described later, the stand (82a) (82b) to stand up when not using the footrest 90 Saddle 80 is used to raise.

On the other hand, the support (82a) (82b) for supporting the saddle 80 in the above may be fixed by using the hook groove 86, a pin hole (not shown) using a different structure, for example, pin (not shown) It can be fixed by inserting into (not shown).

The present invention is provided with a foldable footrest 90 in the middle of the frame 10, such a footrest 90 is squat in a standing posture simultaneously with the movement of the bicycle through the forward and backward swing operation of the front handle 60 Enables press, push and pull exercises. As shown in FIG. 6B, the scaffold 90 has a plate-like structure in which a lower end thereof is connected to the middle of the frame 10 through a hinge 92.

Such scaffold 90 can be structurally transformed to maintain a vertically folded state or horizontally unfolded state through the hinge 92 of the lower edge.

work

As shown in FIGS. 7 and 8, the whole body exercise progressive bicycle 1 according to the present invention configured as described above includes a squat movement, a press movement, and a push movement while moving the bicycle forward. And it is possible to obtain a whole body exercise effect by performing a pull exercise.

First, when the first picture of Figure 7 (a) is used as a general bicycle, the second to the fourth of Figure 7 (a) has been switched to the case of performing the press movement while the pedal (5) movement.

In this case, the user rotates the first drive sprocket 24 using the pedal 5 of the first drive unit 20, rotates the rear wheel 12b using the chain 22, and then rotates the bicycle. Make progress. At the same time as the forward movement using the pedal pulls the telescopic portion 70 provided on the front handle to the upper side. Then, when the handle is lowered to the shoulder position and lifted up as in the case of the press motion, as shown in FIG. 7 (a), the angle of the front handle 60 axis is changed and the length of the telescopic portion 70 is changed. In this case, when the handle is lifted, the rotating rod 62 and the arc gear 48 connected to the front handle 60 are swinged together, and the arc gear of the second drive unit rotates the rotary gear 42. The rotational force is transmitted to the first drive through the chain 46. This driving force transmits resistance to the user when lifting the handle, and acts like a load of the actual press motion, leading to the effect of the motion. On the other hand, the driving force through this movement is transmitted to the first driving unit is converted into the forward driving force of the bicycle to generate additional driving force in addition to the driving force by the pedal movement.

As described above, the press motion of the lifting operation is a case in which the rotary gear 42 is bitten by the left gear 48c of the arc gear 48, and the force that the user must exert is the user's own driving force along with the driving force of the bicycle. There is also a role of lifting part of the weight, because the user's weight itself is in a position to act as a force to pull the front handle 60 toward the user. Therefore, when the rotary gear 42 is bitten by the left tooth 48c, it is preferable to increase the effect of strength exercise by giving a sufficient load to the user, and the operation of lowering the front handle 60 is made by the user's weight. will be.

Alternatively, the pull motion of pulling the front handle 60 downward is also possible in the state of FIG. 7 (a), as described above, in which the rotary gear 42 is placed on the right gear 48d of the arc-shaped gear 48. In this case, even when the user's weight itself is in a position that acts as a force for pulling the front handle 60 toward the user, part of the user's weight can be combined with the user's pulling force to transmit a greater driving force. Higher gear ratios can be used, which is more advantageous for speed increase. At this time, even in the operation of pushing up the front handle 60, due to the action of the user's weight described above, it also serves as an exercise effect of pushing up a part of the user's weight.

And as shown in Figure 7b), squat (quat) and front (front) movement can be performed in parallel.

In such a case, the user first extends the front handle 60 and extends the footrest 90 while standing on it and then folds the saddle 80 to lower its position. In this state, when the forward and backward swing motion of the front handle 60 is performed, the rotational force of the second drive unit 40 according to the forward and backward swing of the front handle 60 is transmitted through the first drive unit 20 to the rear wheel 12b. The bike moves forward and balances.

When the footrest 90 is used as described above, the user may naturally squat on the footrest 90 and stand up to perform a squat (squat) movement to transfer the driving force by lifting the front handle 60. At the same time, a front press motion can also be performed. In this case, when the front handle 60 is lifted up and down over the shoulder, the length of the front handle 60 is adjusted to the motion by the telescopic 70 part. Since the swing angle of the front and rear handles 60 is also changed through such a lifting and lowering operation, the driving force of the bicycle is activated, and the press motion can be performed in parallel. Here, the lifting motion is a case in which the rotary gear 42 is bitten by the left gear 48c of the arc gear 48. As described above, the force that the user must exert is a part of the user's weight along with the driving force of the bicycle. Since it also has a role of lifting, when the rotary gear 42 is bitten by the left gear 48c, it is desirable to increase the effect of strength exercise by giving a sufficient load to the user, the operation of lowering the front handle 60 is the user It will be done by weight.

In addition, in a standing position, the pull motion of pulling the front handle 60 downward is possible. As described above, the rotary gear 42 rotates clockwise forward when the arc gear 48 descends counterclockwise by the pulling motion. By generating the driving force of the bicycle, the rotary gear 42 is in the case of the right gear 48d of the arc-shaped gear 48, even in this case the weight of the user itself pulls the front handle 60 toward the user Since it is in the position acting as the force coming in, part of the user's weight can be combined with the user's pulling force to transmit a larger driving force, and thus a high gear ratio can be used, which is advantageous for speed increase. At this time, even in the operation of pushing up the front handle 60, due to the action of the user's weight described above, it also serves as an exercise effect of pushing up a part of the user's weight.

In addition, the present invention, as shown in Figure 8, can perform a push (pull) motion and a pull (pull) movement in parallel with the exercise of the pedal (5).

In this case, the user rotates the first drive sprocket 24 using the pedal 5 of the first drive unit 20, rotates the rear wheel 12b using the chain 22, and then rotates the bicycle. Make progress. And in the state of the forward movement of the bicycle can be carried out by pushing the front handle (60) to push forward or pull back movement according to the user's will.

In this case, in the push motion situation in which the front handle 60 is pushed forward, as described above, the rotary gear 42 is bitten by the left gear 48c of the arc-shaped gear 48, and the user must exert it. In addition to the driving force of the bicycle has a role of pushing a part of the user's own weight, because the user's weight itself is in a position to act as a force to pull the front handle 60 toward the user.

Pull motion of pulling the front handle 60 is possible when the rotary gear 42 is bitten by the right gear 48d of the arc-shaped gear 48, as described above. 60) is in a position to act as a force to pull toward the user, so that a part of the user's weight can be combined with the user's pulling force to transmit a larger driving force, so that a higher gear ratio can be used, which is more advantageous for speed increase. In this case, even when the front handle 60 is pushed forward, due to the action of the user's weight described above also serves as an exercise effect to push a part of the user's weight.

When the push motion and the pull motion are performed, the rotational force through the arc gear 48 and the rotary gear 42 of the second drive part 40 is reduced in addition to the pedal 5 motion made by the first drive part 20. In addition to the first driving unit 20, the rotational force of the rear wheel 12b can be strengthened, thereby obtaining an effect of advancing the bicycle at a higher speed.

As described above, the present invention is not only a pedal 5 movement, but also a squat movement, a press movement, a push movement, and a push through the operation of the first driving unit 20 and the second driving unit 40 together with the bicycle driving. By doing push and pull exercise together, you can overcome the monotony and postural stiffness of a regular bike and combine the whole body exercise.

And the present invention can move while feeling a sense of speed by moving at a faster speed than a normal bicycle proceeds only by stepping on the pedal (5), as well as a full-body exercise while riding a bicycle, without having to feel bored Can do a kind of exercise.
