Description

BICYCLE TYPE HORSE-RIDING APPARATUS [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle type equestrian exercise device, and more particularly, to a bicycle type equestrian exercise device capable of increasing a motional effect through a whole body exercise such as horse riding while feeling the exercise effect of riding a bicycle.

Generally, a horse-riding exercise device includes a horse-riding robot that implements the movement of a horse in a 3D virtual environment, a power-driven (e.g., electric motor) riding exercise machine that moves eight characters along the vertical direction, There is a riding bicycle that uses weight and weight shift of the user.

The devices using equestrian movements stimulate the unused muscles evenly to help the whole body exercise, and the calorie consumption per hour of riding is relatively higher than jogging and swimming, helps to maintain the posture and to enhance the sense of balance, Can be used for energy-intensive exercises, is effective in decreasing body fat and increasing muscle strength, promoting diet and spine health, and is said to be excellent for bowel movements and constipation.

However, the horse riding exercise machine of Patent Document 1 or the electric energy use riding exercise machine which is the background of the invention is very expensive and requires a complicated operation device for simulating actual horse movements, it's difficult.

The riding type saddle for bicycle of Patent Document 2 is a saddle which is applied to a bicycle or a bicycle for a health, in which the saddle moves up and down and moves forward and rearward in a sliding manner.

However, since the up-and-down and back-and-forth movement of Patent Document 2 uses a spring and a guide portion, it is generated irregularly due to the weight movement of the user and impact that may occur during bicycle travel, Because you have to continue to apply muscle strength while sitting on the saddle, muscle fatigue increases fatigue.

In addition, the upward and downward movement and the back and forth movement of Patent Document 2 may occur bodily when riding a bicycle, because the spring responds to the direction in which the user applies force only in a direction in which the spring exerts a repulsive force.

In addition, the riding type saddle for bicycle according to Patent Document 2 can not change the elastic force of the spring during the movement, stores the elastic force of the inner spring, repeatedly or repeatedly uses the stored elastic force of the inner spring in combination with the elastic force of the outer spring As there is no means for regular implementation, the saddle can move rapidly from below the user's hip to the upper side, or move up or down using a relatively weak elastic force (e.g., elastic force of the outer spring alone) It is not possible to regularly generate a two-step up and down movement using a strong elastic force (for example, an elastic force of an outer spring and an inner spring).

In addition, the riding type saddle for bicycle according to Patent Document 2 has a disadvantage in that it causes pain to the user's buttocks during prolonged use because the user's buttocks must be closely contacted to the saddle for riding exercise. The elastic force can not be changed on the way.

In addition, the bicycle having the riding action function disclosed in Patent Document 3 has a ride-up bar and a cam so that a riding-driving function and a general bicycle can be selected and enjoyed.

However, the cam and the ascending / descending bar in Patent Document 3 merely induce the upward or downward movement of the saddle, and can not use the stored elastic force at once because of storing the elastic force, and can not implement the two-step up and down movement regularly.

First Embodiment

1 is a side view of a bicycle type riding exercise machine according to a first embodiment of the present invention.

Referring to FIG. 1, the first embodiment may include a support frame 10, a bicycle frame 100, a pedal drive unit 200, a volumetric stretching module 300, a handlebar 400, and a saddle 500 have.

The variability elasticity module 300 and the saddle 500 form one set, and can be attached to a general bicycle.

The support frame 10 is installed to be supported on the bottom surface.

The bicycle frame 100 is provided with a support frame 10 instead of a wheel.

The pedal driving unit 200 may further include a speed adjusting unit 220 installed in the center chute 14 to perform a lower body movement with the pedaling unit 201 and capable of adjusting the speed of the pedal.

The variability elasticity module 300 is connected between the bicycle frame 100 and the saddle 500 and selectively transmits the resultant force of the elastic force of the outer spring 310 and the inner spring or the elastic force of the outer spring 310 to the saddle 500, So that regular two-step up and down movement can be performed. That is, the variability elasticity module 300 can exhibit the equestrian effect. Herein, the horse-riding effect may mean that the saddle is hammered at a stable and constant interval by changing the expansion or contraction of the outer spring 310 or the inner spring 320 to regular exercise.

The handle bar 400 has four knobs in combination with the numbers "2" and "5 ". The user's hand is able to move up and down like the four knobs and by changing the position of the user's upper body by changing the position to hold, it is possible to move the upper body arm, shoulder, It plays a role.

The saddle 500 is a device connected or detachably coupled to the modulus expansion and contraction module 300 located below the saddle 500. The saddle 500 induces a horse-riding effect through a function of moving up and down in two stages. The saddle 500 is manufactured to have a horse-like shape, and has a longitudinal length 1.5 times longer than that of a saddle of a general bicycle.

10, the outer spring 310 or the inner spring 320 may be provided in the spring set S1 or S2 so as to have different elastic moduli according to the weight of the user, . The module main body 330 may be detachably coupled to the lower housing core 340 of the variable elasticity expansion module 300 in order to replace the outer spring 310 or the inner spring 320. [

1, the support frame 10 is installed such that a pair of support bars 12a and 212b facing each other at regular intervals are supported on the bottom surface in the form of a cylinder or a polygon, 12a, and 12b.

The center support portion 14 is formed with a predetermined thickness and height to form a space therein.

The bicycle frame 100 includes a front end tube 101 installed vertically to the front end support bar 12a and a rear end tube 102 installed perpendicularly to the rear end support bar 12b, And a cushion frame 110 seesawing based on the tube 101.

The cushion frame 110 includes a yoke 111 yoke rotatably coupled to the hinge 108 of the front end tube 101 and a yoke 111 yoke 111 extending from the yoke 111 toward the rear end tube 102 A cantilever 112 and a cantilever 112 to which a post mounting portion 113 provided at an end of the cantilever beam 112 and a module post 114 to be fitted to the post mounting portion 113 are fixed to the post mounting portion 113 And a post clamp 115, as shown in FIG. Here, the post clamp 115 can be used for adjusting the height of the module post 114, such as a hollow shaft member fitted in the post mount 113. [

That is, when the user releases the post clamp 115, the post mounting portion 113 is loosened, and the module post 114 can be moved upward or downward. Conversely, when the post clamp 115 is locked, the post mounting portion 113 is brought into close contact with the module post 114, and the module post 114 can be held in a fixed state.

In addition, the bicycle frame 100 includes a plurality of shock absorbers 120, 130, and 140 connected to each other in the vertical direction (Z-axis direction) or the front-rear direction (X-axis direction). The connection points of the respective rings of the shock absorbers 120, 130 and 140 in the following can be connected by bolts and nuts. At this time, using a suitable tool (such as a socket wrench), the nut can be detached or fastened from the bolt.

The cushion shock absorber 120 connects one side ring to the upper bracket of the center support portion 14 and connects the other side ring to the bottom bracket of the cantilever 112 of the cushion frame 110. The cushion shock absorber 120 can exhibit the cushioning effect, the comfort and the seesaw effect.

The front cushion shock absorber 130 connects one side ring to the rear bracket of the front end tube 12a provided at the upper side of the hinge 108 and connects the yoke 111 and the cushion frame 110 And the other side is connected to the front bracket.

The rear shock absorbing shock absorber 140 connects one side ring to the rear bracket of the post mounting portion 113 and connects the other side ring to the upper bracket of the rear end tube 102.

The front cushion shock absorber 130 and the rear cushion shock absorber 140 can exhibit the shock-absorbing effect.

Further, the bicycle frame 100 may further include a lower bracket 109 provided so as to be spaced apart from the rear end tube 102 by a length of the rear shock absorber 140 downward.

Particularly, after the bolts or nuts are loosened, the rear shock absorbing shock absorber 140 is rotated about the center of rotation after separating the one side ring to the rear bracket of the post mounting portion 113, and the lower side bracket 109 of the rear end tube 102 (Eg, reassembly of bolts and nuts).

 In this case, the variability of the seesaw motion of the cushion frame 110 can be relatively increased.

In other words, the cushion frame 110 can have a greater fluctuation width in a more rhythmic manner.

Since the rear shock absorber 140 can be stored between the upper bracket 109 and the lower bracket 109 of the rear end tube 102 without being completely removed from the bicycle frame 100, Non-use can be determined.

The plurality of shock absorbers 120, 130, and 140 together with the variability elasticity module 300 can be used to move the saddle 500 up and down in a cushion and shock relieving manner, (A seesaw motion in which the seat 500 moves forward or backward).

At this time, the operation of the saddle 500 by the volatility expansion / contraction module 300 is not limited to the operation of moving the saddle 500 from the lower side to the upper side of the user's sweater quickly or by using a relatively weak elastic force (e.g., elastic force of the outer spring 310 alone) It is possible to regularly generate two-stage up-and-down motions using up-down motions or relatively strong resilient forces [e.g., the sum of the elastic forces of the outer springs 310 and inner springs]. The two-stage vertical motion is described in detail below.

For example, the plurality of shock absorbers 120, 130, and 140 have a general spring damper configuration, and exhibit an irregular expansion / contraction action of the spring.

On the other hand, the variability elasticity module 300 further includes internal components to be described below so as to cause a regular riding operation similar to a user riding a horse.

2 is a perspective view of the handlebar shown in FIG. 1, and FIG. 3 is a front view of the handlebar shown in FIG. 2. FIG.

Referring to FIGS. 1 to 3, as described above, the bicycle frame 100 has a handle bar 400 formed of a combination of two-letter and five-letter shapes.

The handlebar 400 includes a stem 401 coupled to an upper portion of the front end tube 12a of the bicycle frame 100, a first stage handle 410 extending horizontally on both sides of the stem 401, The handle 401 and the two-stage handle 420 are extended upward from the upper ends of the stem 410 and the upper and lower ends of the handle 410, respectively. 430).

In particular, the left and right two-stage knobs 420 are bent at a first angle G1 of 15 to 20 degrees so that the Z-axis is inclined in the Y-axis direction on the YZ plane as shown in FIG. As shown in FIG. 1, bending is performed at a second angle G2 of 25 to 30 degrees such that the Z axis is inclined in the X axis direction on the XZ plane, that is, toward the front (e.g., leftward in FIG. 1) .

The values of the angles G1 and G2 are values for maximizing the upper body movement and comfort of the user. In the range below or below the numerical range, the user may excessively bend the wrist holding the second-stage grip 420, So it has a critical meaning.

In addition, the handlebar 400 further includes a lower handle 440 extending downward from the lower ends of both ends of the first-stage handle 410 rearwardly. The lower handle 440 may have a curved shape similar to or similar to the handle bar for a cycle bike.

Further, rubber grip portions may be further coupled to outer surfaces of the first-stage knob 410, the second-stage knob 420, the third-stage knob 430, and the lower-stage knob 440.

In addition, the stem 401 or the first-stage handle 410 may be further provided with a dashboard 402 for displaying the distance and calories of exercise and detachably attaching the smartphone.

FIG. 4 is an exploded perspective view of the variable elasticity expansion module shown in FIG. 1. FIG.

Referring to FIG. 4, the two-stage up-and-down motion of the above-described volatility expansion and contraction module 300 includes two external springs 310, an internal spring 320, Can be implemented through the upper housing section 330, the lower housing section 340, the stationary hanger 350, the swing section 360, the hanger section 370, the pusher 380, and the upper housing section 390. That is, the two-step up and down movement may mean that the expansion and contraction is performed regularly in comparison with the irregular movement of the outer spring 310 or the inner spring 320.

Particularly, since the spring type of the outer spring 310 and the inner spring 320 selectively uses a spring load (e.g., elastic modulus) according to the user's weight, . ≪ / RTI >

The external spring 310 and the internal spring 320 of the variability elasticity module 300 can be distinguished by weight strength or spring load (kgf).

For example, the spring load of the basic external spring 310 is 20 kgf, which is 40% of the body weight, and the spring load of the basic internal spring 320 is 10 kgf, which is 20% of the body weight. Here, 1 kgf can mean the magnitude of the standard gravity acting on an object with a mass of 1 kg.

At this time, a load of 60% of the weight of the user can be applied to the outer spring 310 and the inner spring 320 through the saddle, and a load of 40% of the remaining weight can be applied to the pedal of the riding bicycle have. The user can enjoy the effects of up and down, back and forth movement and equestrian by repeating the load dispersion movement with respect to the pedal side or the saddle side.

In addition, the weight strength (spring load) of the outer spring 310 and the inner spring 320 can be changed according to the user's taste.

Fig. 11 is a view for explaining the coupling relationship of the saddle shown in Fig. 1. Fig.

The locking hook 350 can be fixed by welding after being inserted into the opposite position of the pusher 380, that is, the upper inner side of the module body 330. [ For example, a welding bead may be formed through welding at a point where the surface of the fixing hook 350 contacts the surface of the module main body 330, or a boundary line portion corresponding to the surface contact.

6, the knob 362 includes a plurality of guide protrusions 363 formed on the outer circumferential surface of the knob 362 so as to be slidably inserted into the guide hole 351 and the guide groove 352.

5 and 6, each of the guide protrusions 363 has a protrusion height of a size large enough to be inserted and slidable corresponding to the groove depth of the guide groove 352. [ Therefore, each guide projection 363 can be inserted and slid in the guide hole 351 as well.

Referring back to FIG. 4, the length H1 of the guide protrusion 363 in the up and down direction corresponds to the length of the knob 362 in the vertical direction. That is, the guide protrusion 363 contacts with the guide groove 352 and the guide hole 351 of the fixing hook 350 in proportion to the size of the surface area of the up-and-down extension length H1 of the guide protrusion 363, And as a result, the variable shaft portion 360 can be firmly supported so as not to be excessively shaken in the horizontal direction.

The knob 362 includes a V-shaped guide surface 364 formed on the bottom surface of the side wall of the knob 362 in a corresponding number of the guide protrusions 363 along the circumferential direction.

The variable springs 370 include ribs 373 formed on the outer circumferential surface of the hollow rotary gear 372.

7 is a cross-sectional view taken along the line C-C shown in Fig.

5 and 7, the rib 373 is larger than the groove depth of the guide groove 352 and protrudes corresponding to the depth of the guide hole 351. Therefore, although the rib 373 can be moved up and down along the guide hole 351, the stop vertical movement can be stopped from the outside of the guide groove 352 corresponding to the stopping jaw 353.

4, the up and down extension length H2 of the rib 373 of the variation hook 370 is formed to be slightly longer than the vertical length of the hollow rotary gear 372. As shown in Fig. The rib 373 can be moved up and down while being in contact with the guide hole 351 of the fixing hook 350 in proportion to the size of the surface area of the upper and lower extension length H2 of the rib 373, So that the support member 370 can be firmly supported so as not to be excessively shaken in the horizontal direction.

An inclined surface 374 is formed at the upper end of each of the ribs 373 of the fluctuation hook 370 so as to be in contact with the guiding surface 364 of the knob 362 of the fluctuation shaft portion 360.

The inclined surface 374 is vertically moved along the guide hole 351 of the fixed hook 350 in a state of being in contact with the guide surface 364 in a slippery relationship with the guiding surface of the guide hook 351. At this time, The changing hook 370 itself is only moved up and down, and is not rotated in the circumferential direction.

On the other hand, when the guide hole 351 is moved out of the guide hole 351 during the vertical movement, it is possible to generate a rotational force capable of rotating the change hook 370 by the slip treatment relationship.

FIGS. 8 and 9 are combined cross-sectional views of the variational stretch module shown in FIG.

8 shows a state in which the rib 373 of the variation hook 370 and the guide projection 363 of the variation shaft 360 are arranged in the guide hole 351 of the fixing hook 350. [

9 shows a result of an external force (for example, a force transmitted through the buttocks or a saddle in a vertical direction) acting on the variable shaft portion 360, and the variable shaft portion 360 is rotated by the external force, The variation hook 370 having the inclined face 374 is rotated due to the slippery relationship between the inclined face 374 and the guide face 364 during the ascending when the external force is weakened or removed, Only the variable shaft portion 360 is shown in an elevated state.

At this time, the variable shaft portion 360 is elastically supported by the outer spring 310. In addition, the inner spring 320 can remain compressed through the pusher 380. The compressed state may be a state where elastic force is stored in the inner spring 320.

9, in the case where an external force in the up-and-down direction further acts on the variable shaft portion 360, the variable shaft portion 360 and the variable spring 370 are returned to the state shown in Fig. 8 again in accordance with the following operation principle . The detailed operation description of Fig. 8 or Fig. 9 can be explained with reference to Figs. 12 to 14. Fig.

On the other hand, when an up / down external force further acts on the variable shaft portion 360 in the state of FIG. 9, the variable shaft portion 360 and the variable hook 370 return to the state shown in FIG. 8 again in accordance with the following operation principle .

That is, the two-stage up-and-down motions may occur regularly in response to the action of the external force.

In the two-step up and down movement, the variable shaft portion 360 moves up and down along the guide groove 352 and the guide hole 351 of the fixed hook 250, and the variable hook 370 is also pressed by the pusher 380 and the inner spring 320 The swing hanger 370 is stopped once at the top and once at the bottom while the swing hanger 370 is stopped during the up and down movements, As a result, the horse riding effect can be exhibited.

Since the wedge portion 384 of the contact projection portion 383 of the pusher 380 is in point contact with the ceiling of the inner space of the hollow rotary gear 372 of the variation hook 370, The impact noise can be reduced.

10 is a side view for explaining a method of replacing the external spring and the internal spring in the variable elasticity expansion module shown in FIG.

The saddle 500 further includes a saddle space portion 540 formed along the longitudinal direction of the saddle 500 in the middle of the upper surface of the saddle 500 for preventing slippage.

Also, the saddle 500 is manufactured in a symmetrical shape with respect to the saddle space part 540, and can be made of a soft material for cushioning feeling or comfortable feeling.

Also, the present invention includes an upper seating block 160 connecting the modulus expansion and contraction module 300 and the saddle rail 510 of the saddle 500 together.

The bottom surface of the lower seating block 160 is welded to the upper surface of the module post 114 and the upper surface of the upper seating block 160 is welded to the saddle 500 The saddle rail 510 of FIG.

Here, the stationary bracket 520 is on the saddle rail 510. Then, the coupling bolt 530 passes through the bolt hole of the stationary bracket 520 and is fastened to the bolt hole on the upper surface of the upper seating block 160. As a result, when the coupling bolt 530 is tightened, the bottom surface of the saddle rail 510 of the saddle 500 and the top surface of the upper seating block 160 can be brought into close contact with and fixed to each other.

The upper surface of the lower seating block 150 is provided with a fixing protrusion 341 of the lower housing complex 340 corresponding to the cross sectional shape of the lower housing complex 340 of the variational elasticity module 300, An upper insertion hole 151 is formed in the upper and lower direction of the lower seating block 150 for mutually interlocking insertion.

At this time, a bolt hole 152 is formed in a side surface of the lower seating block 150 so as to be connected to the upper insertion hole 151 and the connection hole 345 of the fastening protrusion 341 of the lower housing complex 340 Respectively.

The bolt and nut may be coupled to the connection hole 345 and the bolt hole 152 and the variable elastic expansion module 300 may be detached or installed from the lower seating block 150 through disassembly or reassembly of the bolt and nut have.

The bottom surface of the upper seating block 160 is formed with a sectional shape of the upper circumference 390 of the upper limit of the upper circumference 390 of the modulus of elasticity expansion module 300, A lower insertion hole 161 for inserting the fastening protrusions 391 of the upper mounting block 160 in the upper and lower directions of the upper mounting block 160 is formed.

A bolt hole 162 is formed in the side surface of the upper seating block 160 so as to pass through the lower insertion hole 161 and the coupling hole 394 of the fastener protrusion 391 . The bolt and nut may be coupled to the connection hole 394 and the bolt hole 162 and the variable elasticity expansion module 300 may be detached or separated from the upper seating block 160 through disassembly or reassembly of the bolt and nut. Can be installed.

Hereinafter, the operation principle of the variability elasticity module 300 will be described.

Figs. 12 to 14 are schematic cross-sectional views for explaining the operation principle of the variably stretchable and contractible module shown in Fig.

12, the modulus of elasticity expansion / contraction module 300 utilizes the elastic force of the outer spring 310 and the inner spring 320.

The left side of FIG. 12 is a state before the external force F in the up-and-down direction is applied, and may correspond to the sectional view shown in FIG. The right side of FIG. 12 shows a state in which an external force F is applied.

12, the inner spring 320 is configured to transmit the elastic force of the inner spring 320 to the rib 373 of the changing hook through the pusher 380 that performs the push function and the weight moving body function .

That is, in the left state of Fig. 12, the variable shaft portion 360 elastically deforms the saddle and the buttocks of the user using the resultant force of the elastic force of the outer spring 310 and the inner spring 320 until the right state of Fig. Can support.

The outer spring 310 is configured to transmit an elastic force to the guide protrusion 363 of the variable shaft portion 360.

The guide projections 363 of the variable shaft portion 360 and the ribs 373 of the variable hooks are slidable in the guide holes 351 of the fixed hooks 350. At this time, 364 are in contact with the inclined surfaces 374 of the ribs 373 and can be kept in contact with each other by the elastic force of the outer spring 310 and the inner spring 320.

12, when the external force F moves the variable shaft portion 360 downward, the guide protrusion 363 of the variable shaft portion 360 and the rib 373 of the change hook are engaged with the fixing hook 350 And moves downward along the guide hole 351.

In this process, the rib 373 of the changing hook exits the guide hole 351 of the fixing hook 350, but the guide protrusion 363 of the changing shaft portion 360 may remain in the guide hole 351 .

The rib 373 and the inclined surface 374 of the variable hinge 360 are not moved along the guide surface 364 of the variable shaft portion 360 while the variable shaft portion 360 is not rotated by the guide protrusion 363 under the elastic force. It is slidably raised and rotated. As a result, the inclined surface 374 of the rotated rib 373 is placed on the first projecting retention surface 354 of the retention hook 350.

Referring to the left side of FIG. 13, as the user moves the body weight toward the pedal, the hip portion of the user pressing the saddle is moved upward so that the external force F becomes weaker than the elastic force of the external spring 310 .

The guide projection 363 of the variable shaft portion 360 is also engaged with the guide hole 351 of the fixing hook 350 so that the guide projection 363 of the variable shaft portion 360 is inserted into the guide hole 351 of the fixing hook 350, As shown in FIG.

On the other hand, the rib 373 and the inclined surface 374 of the variable hook, which are subjected to the elastic force of the inner spring 320 through the pusher 380, are slid along the first projecting retention surface 354 of the retaining hook 350 Up and rotate. As a result, the inclined surface 374 of the rotated rib 373 remains stationary at a lower position, such as the stopping jaw 353 of the fastening hook 350. Such a state can correspond to the sectional view shown in Fig.

In this state, even if the external force F is applied to the variable shaft portion 360 again, only the elastic force of the external spring 310 can be used to repel the external force F. [

That is, in the right side of Fig. 13, the variable shaft portion 360 can elastically support the saddle and the buttocks of the user using only the elastic force of the external spring 310. [

The internal spring 320 is in a compressed state and is moved up and down by the variable shaft portion 360 until the guide surface 364a of the variable shaft portion 360 comes into contact with the inclined surface 374 of the rib 373 of the variable spring. The elastic force of the inner spring 320 can not be transmitted. Here, the compressed state may mean that the elastic force of the inner spring 320 is stored.

On the other hand, the stopper 353 of the fixing hook 350 is positioned at the end of the guide groove 352.

At this time, the guide protrusion 363a of the variable shaft portion 350 is disposed in the guide groove 352 of the fixing hook 350, and the guide surface 364a is positioned below the guide protrusion 363a.

Further, the external force F can be applied to the variation shaft portion 360 more greatly than the elastic force of the external spring 310. [

In this case, the variable shaft portion 360 is moved downward again.

The guide protrusion 363a of the variable shaft portion 360 also moves downward along the guide groove 352 of the fixing hook 350 to be as shown in Fig.

14, after the guide surface 364a of the variable shaft portion 360 comes into contact with the inclined surface 374 of the rib 373 of the change hook, the elastic force of the outer spring 310 and the elastic force of the inner spring 320 And the resultant force of the stored elastic force can be used to repel the external force F. [

Then, when the variable shaft portion 360 is moved downward continuously after the guide surface 364a contacts the inclined surface 374, the rib 373 of the varying hook is moved out of the guide groove 352 of the fixed hook 350 And then passes over the stop jaw 353.

The rib 373 and the inclined surface 374 of the fluctuating hook slide up and rotate along the guiding surface 364a of the variable shaft portion 360 so that the inclined surface 374 of the rib 373 is fixed And is placed on the second projection retention surface 355 of the hook 350.

In addition, when the external force F is removed from the saddle, the saddle and the variable shaft portion 360 are moved upward as they pop up through the resultant force of the elastic force to return to the original upper position.

The rib 373 and the inclined surface 374 of the changing hook are slidably raised and rotated along the second projection retention surface 355 of the fixing hook 350 by using the stored elastic force of the inner spring 320 And reaches the guide hole 351a.

As a result, since the inclined surface 374 of the rib 373 of the change hook receives the resultant force of the elastic force, it moves upward along the guide hole 351a, and then returns to the original upper position.

12 to 14 are repeated so that only the elastic force of the external spring 310 or the external spring 310 is used while the two-step vertical movement, i.e., the floating hook is located at the upper position or the lower position of the fixed hook 350, The movement of elastically supporting the variable shaft portion can be regularly performed by using the resultant force of the elastic force of the inner spring 310 and the inner spring 320.
