Description

Pull-up motion

The present invention relates to the structure of a pull-up motion device, and more particularly, to a position that allows the support plate to be in a low static position before and after being used, which is highly beneficial to the user. The lower support plate is a novel invention that smoothly performs the expected movement and is safe, practical and progressive.

According to the so-called "pushup-up exerciser", it is basically an indoor sports equipment that simulates the gymnastics "horizontal bar" or "hanging ring" movement. Of course, it can also be used to perform upper limb stretching or lower limb squatting. The type of limb movement depends on the user's familiarity with the use of the device and its own sports needs. It can be said that it is an extremely diverse and excellent indoor exercise fitness equipment; it is mostly due to the user's body weight as the movement gravity. The source of the load, therefore, in design, in order to avoid the user's physical strength can not load its own weight multiple times, it is usually provided under the support plate with auxiliary thrusting elements (such as spring pneumatic cylinders, etc.) to help the user's force In other words, when we pull the pull ring unit at the top cantilever with both hands to drive the support plate located at the lower side to rise, the auxiliary thrusting element will always provide an appropriate and settable upward thrust. To help the user's force to lift the body more easily.

Therefore, as described above, since the auxiliary pushing element constantly pushes the supporting plate, when the supporting plate is not used, it is usually at a certain height position (depending on the pushing length of the auxiliary pushing element) Therefore, when the user wants to step on the support plate, it will be more inconvenient or even Fear, of course, there are also conventional products that use a stepped platform on the side of the raised support plate to facilitate the user to step on the support plate. However, this also makes the user still psychologically afraid. I am deeply afraid that the speed of sinking will exceed its expectations, and even the rejection mentality of resisting use. It is obvious that the design features of this institution are obviously difficult for users to easily agree with.

Moreover, when the user wants to leave the support board after the exercise and fitness, the user will also feel hesitant and tormented. Because the weight of the body leaves the support plate, the support plate is pushed by the auxiliary pushing element. It immediately rises accordingly. Therefore, the user must leave the support plate cautiously and cautiously. However, the accident news of the user who has fallen down on such sports equipment is still known. It is known that the design has potential drawbacks. And there are those who are necessary to improve.

Therefore, in view of the above facts, the inventors have actively invested in research and development based on their practical experience in practicing this industry for many years. The invention has been introduced early; therefore, it mainly uses the top cantilever and the upper and lower support plates. Corresponding relationship, the interlocking action of the interlocking cable, the card screw, the elastic member and the interlocking hook bar, so that the support plate is always at the low static position at the beginning and after use, so as to be above the user The fact that the lower support plate is used to ensure the safety of use is the main object of the invention.

Another object of the present invention is to facilitate the use of the device extremely smoothly for users of various body types and different physical states. Therefore, the height adjustment device of the top cantilever and the angle adjustment device of the pull ring angle fork are respectively provided. The top thrust adjustment device of the auxiliary thrust pushing unit can be used to improve the overall practicality and convenience of the user.

Yes, it mainly consists of a base that can stably support all components and a fixed The column at the rear of the base has a top cantilever at the top of the column, and the end of the cantilever is coupled with a connecting cable, and the other end of the chain can drive a moderate rotation of one of the elastic members. Afterwards, a pull ring unit is arranged at the other end of the cantilever to cooperate with a pull rope and a plurality of pulleys to pull the upper and lower displacement strokes of the support plate; and further, a rotary rod assembly is pivoted at the bottom end of the column. The other end of the rotating rod assembly is pivotally connected with a supporting plate, and between the rotating rod assembly and the base, an auxiliary pushing unit capable of adjusting the top thrust is provided to provide an appropriate upward pushing of the supporting plate. In addition, at the first pivot point of the rotary rod assembly, there is a coaxial connection and a linkage hook rod, and the corresponding hook column of the card rotation piece is used to constantly lock the low position static position of the rotation rod assembly and the support plate.

In order to further understand the technical means and features of the present invention, it is described in detail with a number of drawings: First, please refer to the first, second, third, fourth and fifth figures, which is a preferred embodiment of the present invention. The figure shows that the base 10 includes a base 10 that can stably support all components, and a column 20 that is fixed to the rear of the base 10. A top cantilever 30 is pivoted to the top of the column 20, and the ends of the cantilever 30 are coupled. There is a connecting cable 31, and the other end of the connecting cable 31 can drive a moderate rotation of one of the latching blades 33 by the elastic member 32. Thereafter, the pull ring unit 40 is disposed at the other end of the cantilever 30. By the action of a pull cord 41 and a plurality of pulleys 42 to pull the upper and lower displacement strokes of the support plate 50 (ie, as shown in the fifth figure); and further, a rotary rod assembly 51 is pivoted at the bottom end of the column 20, and The other end of the rotating rod assembly 51 pivots the supporting plate 50, and between the rotating rod assembly 51 and the base 10, an auxiliary pushing unit 60 capable of adjusting the thrust is provided to provide the supporting plate 50. Appropriate upward thrust; in addition, at the first pivot point 511 of the rotary lever assembly 51, there is coaxial The interlocking hook rod 52 is coupled with the corresponding hook post 331 of the locking tab 33 to constantly lock the low position static position of the rotating rod assembly 51 and the supporting plate 50; that is, by the composition of the above components, when the supporting plate 50 The gravitational force (ie, the third and third B diagrams) and the cantilever 30 are simultaneously pulled downward, so that the interlocking hook lever 52 is disengaged from the locking tab 33. In the state, it can be pulled by the pull ring unit 40 to perform the expected motion (ie, shown in the fourth figure), and when the force of the pull ring unit 40 disappears, the support plate 50 will be settled by continuous gravity, and then returned. And the low point static position that is automatically locked is its characteristic.

In other words, when the user (not shown) is used, his or her own weight will cause the support plate 50 to naturally descend slowly before leaving the support plate 50. The user has also released the pair of pull ring units 40. When the force is applied, the elastic member 32 pulls the click tab 33 back to the original snap position, so that the buckle 521 of the linked hook 52 is aligned with the corresponding hook 331. At this time, the user can safely leave the support plate 50. There is no need to worry about an unreasonable escalation (ie, automatic return to the snap position as shown in the second figure), and this low static position will of course be of great benefit to the next user.

Further, as shown in the fifth figure, the rotary lever assembly 51 includes a central support rod 53 and two side rods 54. The open ends thereof are used for pivoting the support plate 50, wherein the central support rod 53 is at the other end. The interlocking hooks 52 are disposed coaxially at the first pivot point 511 of the column 20 to be in a linked relationship, and the side rods 54 are respectively pivoted to the second pivot point 512 of the column 20.

As shown in FIG. 6 , the auxiliary pushing unit 60 includes a set of screw adjusting members 61 disposed on the central strut 53 , a sliding seat 62 that can be adjusted by the screw adjusting member 61 , and a sliding seat 62 . The pivoting spring pneumatic cylinder 63 can adjust the auxiliary thrust of the spring pneumatic cylinder 63 by rotating the knob 611 on the side of the screw adjusting member 61, that is, the closer the spring pneumatic cylinder 63 is to the support plate 50, the pushing The stronger the strength, the weaker the vice versa. Of course, it is better to draw the scale 612 at the appropriate position of the screw adjusting member 61 for the easier grasp of the auxiliary thrust value.

Thereafter, as shown in the seventh and eighth figures, the rear end of the cantilever 30 is inserted into the hollow section 21 at the top end of the column 20, and then the shaft joint 201 is used to pivot the two, and the front end is fixed with a plurality of options. The curved plate 302 of the jack 301 is configured to cooperate with an extending fork arm 304 having a spring puller 303. The height and the low position of the extension fork arm 304 can be adjusted; the extension fork arm 304 is also pivoted to the outer side of the hollow section 21 by the shaft member 201, and the insertion shaft 305 of the spring trigger 303 at the center is inserted. Any one of the arcuate plates 302 is selected in the jack 301, so that when the spring puller 303 is pulled to move the pin 305 away from the original selection jack 301 (shown in the seventh figure), then the desired one can be selected immediately. Adjusting the height and low angle, the pressure of the spring trigger 303 is released, and the built-in elastic member 306 automatically inserts the insertion shaft 305 into the selected selection jack 301 and positions the person.

It can be seen from the above design that since the cantilever 30 is limited by the space of the hollow section 21, it can only be pivoted a limited angle by the shaft member 201, and the finite angle is rotated, In addition, it will only be able to turn the card spinner 33 to achieve the unlocking state of the overall mechanism.

Referring to the first, ninth, tenth, and eleventh drawings, the front end of the extension fork arm 304 is a cross frame 307, and the two ends of the cross frame 307 are sleeves 308 having a plurality of limit grooves 3083. The angled fork 309 is pivoted with a positioning pivot 3081 and an elastic member 3082, and the pull ring unit 40 is connected to the branching section 3091 of the angled fork 309. Then, when the angle is extended, the fork 309 is pulled down. , the locking member 3092 is separated from the original limiting groove 3083 of the sleeve 308 (ie, shown in FIG. 10), and the angle fork 309 can be immediately turned to the desired angle and released, and the elastic member 3082 will be automatically Let the two cards be in the desired angular position.

The pull ring unit 40 includes a pull cord 41, four sets of pulleys 42 and two pull rings 43. Among them, two sets of pulleys 42 are pivotally disposed at the end of the branching section 3091 of the two-angle fork 309, and the other two sets of pulleys 42 is pivotally disposed on both sides of the rear end of the support plate 50, and the pull ring 43 is fixed at both ends of the pull cord 41. Therefore, when the support plate 50 is released, the user pulls any pull ring 43 or simultaneously pulls two The pull ring 43 will be able to pull the upper and lower displacement of the support plate 50.

In addition, as shown in FIG. 12, two armrests 501 are further disposed on both sides of the support plate 50, and a slide plate 502 is disposed on the bottom portion to cooperate with a top rod 503 and an elastic member 504. The support plate 50 is lifted at an oblique angle for the person to sit on the support plate 50 while facing the equipment during the squat exercise, so that, in addition to facilitating the squat exercise, Appropriately provide our stable body and safe grip to prevent accidents such as falls and injuries.

Of course, as shown in Fig. 13, the present invention can utilize the function of an electric motor 70 instead of the manual knob 611 to enable a more rapid adjustment of the auxiliary thrust of the spring pneumatic cylinder 63.

In order to avoid confusion caused by excessive labeling, some drawings only indicate the corresponding drawing number for specific focus. According to the specific content of each section of the manual, it is easy to clearly understand the indicators, please forgive me. .
