Hereinafter, with reference to the accompanying drawings will be described in more detail the cycle exercise mechanism according to the present invention. The following embodiments are merely illustrative of the cycling exercise device according to the present invention, but are not intended to limit the scope of the present invention.

As shown in Figs. 1 and 2, the cycle exercise mechanism 1 to which the present invention is applied is, as in the conventional cycle exercise mechanism, a frame 2 that is generally constructed of steel to form an overall skeleton of sufficient strength. For example, a handle (3) for holding and supporting by hand when exercising, a wheel (4) installed so as to rotate with a constant or variable resistance for an exercise load, and for rotating the wheel (4) through a belt by turning with a foot A pedal 5, and a chair 6 supporting the buttocks.

The organic coupling relationship and operation of these basic components of the cycle exercise device 1 of the present invention may refer to a general description of the cycle exercise device known in the art, and since these structures themselves are not directly related to the present invention, Detailed description thereof will be omitted.

The handle 3 of the cycle exercise mechanism 1 according to the present invention is configured to be rotatable so that not only a function of holding and supporting by hand but also an upper body movement is possible.

To this end, the cycle exercise mechanism 1 of the present invention, as shown in Figures 1 to 3, the handle 3 is installed to be rotatable about the handle post (3a), the handle 3 and the handle post Between (3a) is provided with a resistance device 80 for providing a resistance to the rotation of the handle (3).

The resistance device 80 applies the 'balance exercise force generating device' of the Republic of Korea Patent Application No. 10-2009-0028344 (2009. 04. 02. application) proposed by the present inventor in accordance with the present invention.

As shown in Figs. 3 and 4, the resistance device 80 is configured to include a rotating shaft 81, a housing 83, and a bead liquid 84.

The rotary shaft 81 is connected to the central axis (3b) of the handle 3 and rotates with the rotation of the handle 3, the frictional resistance with the bead liquid 84 around the rotary shaft 81 to produce a handle The resistance blade 82 which raises the resistance applied to rotation of (3) is formed. In addition, a weight 85 may be formed on the rotation shaft 81 to add weight resistance to the rotation of the rotation shaft 81.

The resistance blade 82 is not particularly limited as long as it can cause frictional resistance with the bead liquid 84 in contact therewith, and may be formed in an appropriate shape, arrangement, number, etc. in consideration of the magnitude of the resistance force required for the handle 3. have.

The housing 83 is a kind of casing member in which the rotating shaft 81 and the bead liquid 84 to be described later are accommodated. The housing 83 is enclosed in a tight manner to surround the rotating shaft 81 to form a volume of a predetermined space around the rotating shaft 81. to provide. In the illustrated embodiment, the housing 83 is of a hollow cylindrical shape, the lower end of which is fixed (eg welded) to the handlepost 3a. Preferably, the lower end of the rotating shaft 81 is rotatably supported by the bearing 83a formed below the housing 83.

Accordingly, when the handle 3 is held by both hands and rotates to the left or right, such as steering the handle of the bicycle, as shown in FIGS. 3 and 5, the housing 83 having the rotation shaft 81 fixed to the handle post 3a is provided. Rotate left and right inside.

The bead liquid 84 is a filler that is filled in the housing 83 and applies resistance to the rotation of the handle 3 by applying frictional resistance to the rotation of the rotation shaft 81 in the housing 83.

As the bead liquid 84, a mixed liquid of the beads 84a and the oil 84b is used. The oil 84b is a component for providing fluidity to the bead liquid 84, and the bead 84a is a component for providing a resistance larger than the resistance applied by the liquid to the rotation of the rotation shaft 81.

As the oil 84b that can be applied, oils widely used in various hydraulic actuators such as hydraulic cylinders can be used. The oil 84b can be used by appropriately selecting its viscosity and physical properties in consideration of the magnitude of the resistance applied to the handle 3.

The bead 84a is a granular member (i.e., a bead) having strength and durability that is not easily broken even when colliding with the resistance blade 82. Preferably, the bead 84a is a high-strength ceramic having a spherical shape or an ellipsoidal shape (for example, a roughly grain shape). It is a bead and has a diameter such that it does not fit in the gap between the inner wall of the housing 83 and the resistance blade 82, for example, an average diameter of about 0.1 mm to 2 mm.

Ceramic beads (84a) preferably applied to the present invention, the method of manufacturing a small ceramic bead of Republic of Korea Patent No. 0026141 (announced July 15, 2000), Republic of Korea Patent No. 10-0522460 (2005. 10. 19. can be manufactured by a variety of methods and devices applying the 'small ceramic bead forming apparatus', etc., and can be applied to the purchase of beads having physical properties suitable for the purpose of the present invention.

The mixing ratio of the beads 84a and the oil 84b can be appropriately selected in consideration of the magnitude of the desired resistance force and the characteristics of the oil and the beads used. The higher the content of the beads, the higher the resistance. For example, the oil and the beads may be selected in a ratio of 5: 1 to 1: 5, preferably 1: 1-3, by volume. At this time, if the content of the beads is too high, the lubrication action of the oil is insufficient and the fluidity is lowered, and if the content of the beads is too low, the resistance by the target beads is insufficient.

According to the resistance device 80 of such a structure, when the rotating shaft 81 connected to the center axis 3b rotates left and right by left and right rotation of the handle 3, the resistance blade 82 of the rotating shaft 81 is made into the housing | casing. In the bead liquid 84 of 83, left and right rotations are performed, and a resistance similar to that when the hand is stirred in the mixed water of sand is applied to the handle 3 through the rotation shaft 81.

The resistance applied to the handle 3 is generated relatively uniformly regardless of the rotational direction of the rotational shaft 81 due to the fluidity and frictional resistance of the bead liquid. Therefore, the resistance applied to the upper body by turning the handle 3 is applied. The movement load does not change suddenly and becomes relatively uniform.

In the cycle exercise mechanism 1 according to the present invention, as shown in Figs. 1, 2, 6 and 7, a support bracket 2a extending from the frame 2 is formed under the pedal 5. An elastic device 70 is provided between the pedal 5 and the support bracket 2a. The elastic device 70 provides an elastic force to press the pedal 5 upwards without disturbing the rotation of the pedal (5).

The elastic device 70 is particularly limited as long as the elastic device 70 provides elastic force toward the upper side of the pedal 5 while freely connecting the pedal 5 and the support bracket 2a without interfering with the operation of the pedal 5. Not.

As the elastic device 70, a simple spring or observer which is widely used in general may be used. However, such a general spring or general observer (which has a built-in spring) is rigid because the elastic force of the spring is applied.

Therefore, as the preferred elastic device 70, the 'bead-filled shock absorber' of the Republic of Korea Patent Application No. 10-2009-0083364 (2009. 09. 04. application) proposed by the present invention can be applied to use according to the present invention .

6 and 7, the elastic device 70, the lower end of which is connected to the support bracket 2a rotatably, the cylinder 71, the oil 72 filled in the cylinder 71, the cylinder 71 up and down The piston 73 is reciprocally mounted and is mixed with the piston 73, the upper end of which is pivotably connected to the pedal 5, a spring 74 that exerts an elastic force toward the piston 73, and an oil 72. It includes a bead 75 for resisting the movement of.

That is, the preferred elastic device 70 includes a cylinder 71, oil 72, a piston 73, and a spring 74, similar to a conventional general shock absorber, and beads to the oil 72 of the cylinder 71. 75 are mixed.

In the present elastic device 70, the structure of the cylinder 71, the oil 72, the piston 73, and the spring 74 and the interaction operation relationship can be applied to a conventional shock absorber as it is, Since it is not directly related to the present invention, a detailed description thereof will be omitted.

The bead 75 is a grain member (i.e., a bead) having strength and durability that is not damaged by the impact of the piston 73, and is substantially the same as the bead 84a of the resistor 80 described above. . That is, it is preferably a high-strength ceramic bead of spherical or ellipsoidal shape (e.g., roughly rice grains), and has a diameter such that it does not fit or escape into the gap between the cylinder 71 and the piston 73, preferably larger than the size of the gap. It has an average diameter of about 0.1 mm to about 2 mm, having a diameter of 2 or more times. The mixing ratio of the beads 75 to the oil 72 can be appropriately selected in consideration of the magnitude of the resistive force of the desired elastic device 70 and the characteristics of the oil 72 and the beads 75 used.

1, 2, and 7 show that the support bracket 2a is not installed directly below the lowest pedal 5, but the elastic device 70 when the pedal is rotated to the approximately 150 degree position forward. ) Is an example formed at a position forming a straight line, but is not limited thereto.

As the elastic device 70 of such a structure is connected between the support bracket 2a and the pedal 5, as shown in FIG. 7, when the pedal 5 is exercised by foot, the pedal ( When stepping down 5), the resistance of the elastic device 70 (the elastic resistance of the spring) is added to the rotational resistance of the wheel 4, thereby applying resistance combined with quantum resistance (A and B in Fig. 7). At this time, as the pedal 5 descends, the spring 74 is gradually pressed, and the elastic resistance increases gradually. The elastic resistance of the elastic device 70 is such that the pedal 5 is aligned with the elastic device 70. Maximum at the point (approximately 150 degrees forward) is shown (B in Fig. 7).

The pedal 5 that has passed the maximum elastic resistance force is subjected to a force to rise upward by the restoring force of the spring 74 of the elastic device 70 (C and D in Fig. 7). The other pedal, which is 180 degrees out of phase, will rotate while receiving the same pattern of elasticity.

In general, when the pedal is rotated 360 degrees for the cycle movement, the strongest force is applied from the vicinity of the vertex (0 degree) to the front 90 degree, and the large force is not applied at the remaining angles. When exercising, the user's momentum is concentrated around the front 90 degrees from near the apex.

In the cycle exercise device 1 of the present invention to which the elastic device 70 is applied, the elastic resistance force of the elastic device 70 gradually increases from the front 90 degrees to the 150 degrees (the maximum elastic resistance point), so that a considerable force is applied even in this section. Since the exercise device 1 of the present invention has to be applied, it requires a relatively uniform amount of exercise over the entire rotation period of the pedal.

In the illustrated embodiment, the elastic resistance of the corresponding elastic device 70 generated when one side of the pedal rotates the front 90 degrees-150 degrees, the elastic device of the other pedal to rotate the section of 270 degrees-330 degrees at the same time Although somewhat offset by the elastic restoring force occurring at 70, since the magnitude of the former elastic restoring force is larger than that of the latter elastic restoring force, as a result, the cycle exercise mechanism 1 of the present invention is applied to the two pedals 5 respectively. The interaction between the elastic resistivity and the elastic restoring force of the mounted elastic device 70 requires a relatively uniform amount of momentum over the entire tendon of the pedal.

In addition, in the process of rotating the pedal, the piston 73 descending while receiving the elastic resistance of the spring 74 is first subjected to resistance by the oil 72, and then the valve formed in the cylinder 71 and the piston 73 ( When the oil 72 escapes and the piston 73 starts to pressurize the bead 75, sand grains absorb and cushion the impact force of the golf ball when the golf ball is dropped on a sandy beach. In the same principle, the beads 75 exert resistance against the lowering of the piston 73.

That is, when the piston 73 of the elastic device 70 is lowered and in contact with the beads 75, as if the object falls on the sand, the position of the sand beneath it changes as the contact shape of the object, the bead As the positions 75 change in accordance with the shape of the friction surface 73a of the piston 73, frictional resistance is generated to resist and cushion against the lowering of the piston 73.

More specifically, the piston 73, which overcomes the elastic resistance of the spring 74 and descends, is, in addition to being resisted by the oil 72, from the moment the piston 73 comes into contact with the beads 75 ( The force of 73 is transmitted to the adjacent beads 75 and then sequentially transferred to the far bead 75 as domino phenomenon, friction between the piston 73 and the beads 75, friction between the beads 75, And through friction between the bead 75 and the cylinder 71, a gradual and flexible resistance to the lowering of the piston 73 is applied.

At this time, the resistance force received by the piston 73 is affected by the contact area of the piston 73 in contact with the bead 75, the bottom surface 73a of the piston 73, that is, the piston 73 is bead 75 By forming the bent in various forms on the friction surface (73a) in contact with the), it is possible to change the magnitude of the resistance to the falling of the piston (73).

When the pedal 5 rises past the maximum point of elastic resistance, the elastic restoring force of the spring 74 presses the piston 73 upwards.

As a result, according to the illustrated elastic device 70 applied to the present invention, when the wheel 5 is rotated by rotating the pedal 5, the elastic resistance force and the elastic restoring force of the two elastic devices 70 correspond to the rotational resistance force of the wheel. Combined to give a more uniform and flexible resistance throughout the pedal's entire turn.

1 and 2, the frame 2 is formed high from the ground to allow the rotation of the pedal 5 and the expansion and contraction of the elastic device 70. FIG.
