Description

3-D back anaerobic exercise equipment {3-D Rower}

The present invention relates to a three-dimensional lower back anaerobic exercise device, and more particularly, to present a three-dimensional lower back anaerobic exercise device by using the basic mechanism of the present applicant (application number: 10-2002-0030449), It overcomes the limitations of the 2D back exercise equipment and can take various approaches to the 3D trajectory and the back muscle to increase the concentration on the 3D and lower back muscles, which have a trajectory that makes the back motion safe in the short axis concept. It is to provide a three-dimensional lower back anaerobic exercise equipment to provide safe and efficient exercise for lower back exercise by providing a three-dimensional trajectory.

6 to 8 of the US Patent No. 5769757, the concept of the short axis of the handle is dependent on the angular movement of the short axis link to apply a simple application of the handle angular movement to expose a lot of limitations on the wrist, forearm and shoulder It is not possible to say that safety and diversity, which are excellent characteristics of three-dimensional trajectories, have been reached, including the risk of injury.

The inventor of the present invention has been previously filed for a three-dimensional anaerobic exercise device, and intends to devise a more specific application example.

In particular, it attempted to diversify three-dimensional accessibility by using resistive approach in various three-dimensional trajectories. Examples include independent, dependent, and mixed equations.

In addition, there is a second resistance link system that allows access to various resistance patterns with three-dimensional stability in the resistance method, thereby providing a variety of new possibilities for muscle shock, which is a growth key of human muscles, to prevent growth and injury of the lower back muscles. To provide to the human body.

The present invention is to provide a three-dimensional lower back anaerobic exercise apparatus that can be applied to the lower back part of the human body as the application of the three-dimensional anaerobic exercise apparatus that the inventor has filed.

In particular, the trajectory of the section 4 link (application number: 10-2001-0059147, 10-2001-0078712) concept filed by the present inventors is always shortened as in the present invention, although the handle always maintains an angle perpendicular to the direction of movement. The concept's trajectory makes it difficult for the handle to form an angle close to the direction of motion.

The reason is that the angular movement of the handle link affects the handle, and as a result, g and g 'exist as shown in FIG. 6 of US Pat. No. 5,757,757, which is a problem in the stability of the shoulder, wrist and elbow.

However, if the range of angular movement of the handle is secured to 50 ° to 60 ° or more, as shown in FIGS. 3 and 4, the shape of each handle is the same as that of the four-section link at the start point S and the end point f of the exercise. Level approach and can also be applied to the lower back exercise.

To this end, the handle configuration and the handle link configuration must be in harmony with the movement range of the human body, and the range of the angular movement of the handle must be congested so that the concave trajectory can be conceived. The trajectory should be a certain angle with the chest pad so that the locomotion can be the lower back motion. As the characteristics of the angular motion of the handle link, the distance of each handle at the end point of motion f as shown in the chest press exercise as shown in FIGS. Similarly, in order to absorb the characteristics of the human elbow angular motion at the start point of movement S, the first handle must be located in front of the second handle 13A to be applied to the 3D lower anaerobic exercise equipment.

The three-dimensional torsional resistance device in the trajectory is independent, dependent and mixed, and can approach various amounts and ranges of the three-dimensional resistance according to each method.

The independent type ensures that the angular movement of the handle link does not affect the angular movement of the handle. Typically, a damper of tensile force connects the bottom of the handle link with an arbitrary point of the handle frame.

Dependent equations, such as US patent (5769757), if the amount of the handle angular movement up to 50 ° it is difficult to create a three-dimensional trajectory. Therefore, in order to produce more than 120 ° of torsion, the ball joint's soccer property is similar to the direction of the angular movement of the handle link and the handle frame. In addition, the length of the handle link and the auxiliary link is similar to reduce the volume of each link configuration, the position of the handle and the angular movement lever should be configured integrally, not separated as shown in FIG.

The hybrid type moves up to a certain range like the subordinate equation, and if it exceeds a certain range, it can generate arbitrary torsion by independent resistance method. The damper with compression force is installed in the position and configuration of the subordinate ball joint instead of the auxiliary link.

In addition, the stability of the three-dimensional trajectory can be applied with various trajectories along with various trajectories, and thus aims at various impacts and growths of muscles from the basic resistive pattern of the first resistive link to the opposing resistive pattern of the second resistive link.

The three-dimensional lower back anaerobic exercise device (1) provided by the present invention has a base frame (2) of the approximately L-shaped as shown in Figure 1 fixed the side frame (3) on both sides in front of the base frame (2) and the base The saddle pad 4 and the chest pad 5 are installed on the upper part of the frame 2, and when the user is seated on the saddle pad 4, the handle link 6 is angled forward and left and right. or The bearing housing 24 is installed obliquely in the vertical direction so as to form a front and rear angular movement on the side frame 3, and the bearing box 7 is installed on the upper end of the handle link 6 to form L. The handle frame 8 made of the handle shaft 9 is rotatably installed.

As a result, when the low-movement by holding the handle 13, the handle link (6) is to move up and down angular movement, the handle 13 also to draw a three-dimensional trajectory as shown in Figure 2 in the angular movement within a certain range.

That is, the trajectory as shown in FIG. 2 is an example of the 3D trajectory for the lower back motion.

5 shows the handle link (6) angle At 80 ° and the angle between the handle frame (8) and the handle shaft (9). Is a trajectory that comes from approaching 10 ° and the handle link (6) about 75cm.

Principle for laying the three-dimensional trajectory in which the handle 13 has a torsion of more than 50 ° in the short axis to fit the human body is a limited range (40 to 75 cm) of the breast movement range a of the human body as shown in FIGS. ) Are required.

That is, the human body chest movement range a is limited, but if b is too short ∠ Becomes too large ∠ at starting point S As shown in Fig. 4 for proper wrist angle at the end point f. Must be large, which is trapezoidal close to the triangle, making it difficult to enter the proper upper arm angular range for chest movement, but if b is too long, Becomes too small ∠ at start point S Decreases so that for proper wrist angle at the end point f Must be small, which makes it difficult to enter the proper upper arm angular range for chest movement in a trapezoidal shape close to the rectangle.

As a result, the three-dimensional approach in the shortening concept depends on the angular motion of the handle link 6. Is rewarded in the 4 link concept, but Wow In order to create a stable trajectory in three dimensions. And characteristics of shortened concept Harmonized materials must be placed indispensable.

Otherwise, g and g 'will be present as shown in FIG. 6, rather, a three-dimensional inappropriate shape is formed on the wrist and elbow of the human body.

In the above shortening concept, the approach of the human body of the present invention increases the accessibility of the wrist and the elbow, but eventually has to have a concave trajectory around the human body as shown in FIG.

In the opposite case, it is convex as in the plane trajectory of FIG. 7, resulting in excessive movement of the brachial triceps.

For the concave trajectory, the characteristics of the angular motion must be used as shown in FIG. 9. Therefore, if a section for haptic is set from the starting point S of the handle 13 to the ending point f, the trajectory on the plane may have a concave phenomenon.

7 is a phenomenon due to the direct connection between one side of the handle 13 and the handle shaft 9 due to limitations in the US patent.

If the angular movement of the handle 13 is 50 ° or more when rotating, start the handle 13 at -40 ° to 0 ° in the direction of movement and finish the outside at an angle close to 60 ° to 85 ° in the direction of movement. Will be set. At this time, the handle 13 should be set to move from section II to section I because the angular motion should be felt as much as possible.

To this end, the handle 13 should be positioned in the opposite direction to the human body at the time of contraction of the back muscle with respect to the handle shaft 9. For this purpose, the handle frame 8 connecting the handle shaft 9 and the handle 13 is provided. This must exist.

In the three-dimensional trajectory, the three-dimensional trajectory was established for the safe setting of the three-dimensional trajectory for the wrist and elbow and the approach of the pectoral muscle in the short axis concept. To find out.

The greatest feature pluralism in three dimensions is that two or more handles 13 must be set based on the physiological basis of muscle growth caused by a new impact.

That is, in the press motion as shown in FIG. 4, the first handle 13B starts at a narrow width at the start point of movement S, but the second handle 13A starts at a wider width at the start point of movement S and has different trajectories. It is.

These various trajectory principles act on the back of the human body and provide a great advantage in muscle growth, so the handle 13 of the 3D lower anaerobic exercise equipment must have at least two handles 13 and means for connecting them. That is, the handle frame 8 should be present.

In addition, the shortcomings of the shortening concept, as in the principle of the press motion as shown in FIG. Therefore, only when the second handle 13A is at the rear of the first handle 13B at the movement end point f, there is no angular difference Z so that the first and second handles 13B and 13A can secure the same amount of twist.

As shown in FIG. 4, the second handle 13A moves the angle difference Z by the rear side at the movement start point S, which is equal to the distance moving by Z 'during the angular movement of the elbow. To do this, first set the distance for Z 'and match it to Z. The angle of 되어야 should be similar to ∠Z.

The three-dimensional trajectory was viewed based on the chest press motion, and the present invention should be configured to approach the range a (40 cm to 75 cm) for the lower back motion of the human body, as shown in FIG. Chest pad (5) and the trajectory should be set at a certain angle so as to.

For this purpose, the 3D trajectory is 60cm ~ 110cm and the handle link (6) b to satisfy the lower back motion range a (40cm ~ 75cm). (-10 ° to 30 °), ∠ (60 ° to 87 °), ∠ (90 ° ~ 60 °), and when the back muscle contraction, the handle (13) is located on the outer shell center of the handle shaft (9) and the two or more handles ( 13) the second handle (13A) is located behind the first handle (13B) as shown in Figure 3, but the handle frame (8) is required to make the outside of the upper arm angle shift and the movement destination point at the starting point S 에서 in f By eliminating the distance difference by, the handle link (6) during the angular movement by the twisting of the handle 13 due to the rotation of the handle shaft (9) the three-dimensional trajectory required by the lower back of the human body, and as shown in Figure 3 The tangent at the center of the exercise section is 45 to 85 ° with the chest pad (5) so that the dimensional trajectory is the lower back motion. So to provide the chest movement as the trajectory as shown in FIG.

To add resistance to the three-dimensional trajectory created by the handle link 6, the handle frame 8 and the handle 13 components, it is divided into three approaches, which are independent resistance, dependent resistance and mixed. .

First, in FIG. 10, the independent resistance method is not affected by the forward and backward angular movement of the handle link 6, and a damper having a tensile force by causing a resistance when the human body applies a random twist to the handle 13. ; 10).

The one end of the damper 10 is fixed to the lower end of the handle link 6 and the other side is connected to the fixed lever 11 which induces the angular motion to the handle frame 8 so that the handle 13 is in constant angular motion. In addition, a certain distance difference occurs and the resistance of the damper 10 is generated accordingly to allow the exercise performer to set an arbitrary amount of torsion.

As shown in FIG. 11, when the handle link 6 moves forward and backward as shown in FIG. 11, the handle 13 also moves in a predetermined amount dependently, and the auxiliary link 12 is moved to the ball joint 14 as a means. It is installed on the front side of the shaft (6a) of the handle link 6 and the other side is installed to be orthogonal to each other on the angular movement lever (15) fixed to the handle frame (8).

When the handle 13 and the angular movement lever 15 are separated around the handle link 6 in the volume of the auxiliary link 12 and the handle link 6, the handle as shown in FIGS. 6 and 8. The b of the link 6 may be reduced or the length of the auxiliary link 12 may be increased.

Therefore, the handle 13 and the angular movement lever 15 should be integrally installed in order to reduce the volume of the circular arc formation and the link configuration to go to each length similarly.

In addition, the shaft 14a of the ball joint 14 must be orthogonal rather than parallel in order for the angular movement range of the handle 13 to be more than 50 to 60 °. That is, the effective angle of the general ball joint is up to 50 ° and because of this range, when the direction of the axis 14a of the ball joint 14 is parallel, the maximum angular movement range of the handle 13 is less than 50 ° as shown in FIG. 9. Make.

In fact, the direction of the angular movement of the handle link (6) Wow Although governed by, the ball joint (14) shaft arrangement is nearly orthogonal. Therefore, the shaft 14a of the ball joint 14 must be installed to cross each other so that the angular movement range of the handle 13 can be secured by 150 ° or more.

In the mixing method, as shown in FIG. 12, the auxiliary link is replaced with a damper 10 or a shock absorber in the subordinate structure, and the damper 10 of the minimum length compressed to a predetermined range (60 to 70%) at the movement distance a is assisted. The role of the link 12 and the further movement distance is to allow the angular movement of the handle 13 to give the load of the movement by the resistance of the damper 10 by the arbitrary twist of the exercise performer.

This allows the dependent expression to set the resistance arbitrarily over a certain range of the difference in the amount of torsion according to the arm length, so that the angular movement allowed by the handle frame 8 is allowed regardless of the movement distance a.

12 and 13, if the right handle 13 is the starting point of the movement, the left handle 13 is the end point of the movement. When the handle link 6 performs the circular motion, the lever is connected to a predetermined position of the handle link 6; The link 17 connected at (16) is a ball joint (20, 21) to the lever (19) attached to the first resistance link (18), respectively, when the handle (13) presses forward to the first resistance The link 18 transfers the disk resistor 22 installed in the lower portion of the first resistance link 18 to the handle 13 in an arc motion against power.

At this time, another second resistance link 23 integrally formed on the first resistance link 18 is formed at the upper portion and connected to the disc resistor 22. When the second resistance link 23 is set as a tool to draw out, and the second resistance link 23 sets the resistance link that is felt like the resistance D, and the basic resistance is C, D serves as an auxiliary resistance to diversify the pattern of the resistor. The human body will be able to produce the desired resistance.

As described in detail above, the present invention is to perform the approach of the lower back in the present invention, the trajectory for lower back motion should be provided with the characteristics of absorbing the angular motion and elbow angular motion of the handle link (6) You may want a three-dimensional amount of twist in the four-link.

Therefore, in the present invention, the arrangement of the handle 13 is appropriately made in order to produce the three-dimensional lower back motion in the short axis concept, and the three-dimensional trajectory required by the human body allows the human body to make the lower back motion more safely and efficiently. This can increase the development of the lower back muscles of the human body.

In addition, it is possible to adopt a variety of resistance methods, that is, in the case of the independent type, the range of angular movement of the handle 13 can be arbitrarily adjusted by the exercise performer to create a perfect approach to the target muscle,

Second, in the case of the dependent expression, the trajectory is set to be determined, which is suitable for beginners because it can induce the lower back motion of the human body following the 3D trajectory.

Finally, the mixed equation can be used as a subordinate concept in that it is difficult to establish the trajectory during hyperextension, and can aim for the perfect approach of the target muscle by random twisting during contraction.

The three-dimensional lower back anaerobic exercise apparatus that provides the above various characteristics to the human shoulder area can maximize the growth and safety of the shoulder muscles.
