TECHNICAL FIELD
The present application relates to the field of exercise equipment, and in particular, to a climbing machine.
BACKGROUND
Rock climbing is a sport that has evolved from mountaineering. Rock climbing is a full-body exercise. The simultaneous coordination of hands, feet, eyes, among others in movements can strengthen the muscles of the whole body in a balanced manner. The sport also consumes high energy and can burn a lot of calories within a short period of time to achieve fast fitness.
An existing climbing machine uses resistance, for example, fluid resistance such as wind resistance or water resistance or some form of magnetic resistance. Resistance is used to simulate the feeling of climbing, which, however, is completely different from the real feeling of climbing. Four points in the existing climbing machine are usually relatively fixed two by two. That is, the positions of the hand and foot on the same side remain unchanged relatively, rising and lowering simultaneously. As one side of the climbing machine rises, the other side lowers. This manner is similar to that of a seesaw, and the climbing experience is very poor.

In some specific embodiments, referring to FIG. 1, FIG. 3, and FIG. 5, the climbing machine includes a support 100, a vertical frame 200, two pedals 300 for a user to step on, two handles 400 for a user to hold, a one-way transmission mechanism 500, and a drive unit 600. In these embodiments, the pedals 300 and the handles 400 are all the climbing points. The two pedals 300 and the two handles 400 can respectively move up and down independently. The drive unit 600 can continuously drive the one-way transmission mechanism 500 to run in one direction to drive the two pedals 300 and the two handles 400 to move downward. When any pedal 300 or any handle 400 applies an upward force, the pedal 300 or handle 400 under the action of the force can move upward. In these embodiments, both the hands and feet of a user can be exercised.
In some other embodiments, a quantity of the climbing points 300, 400 is not limited to 4. For example, the climbing points only include the pedals 300 but do not include the handles 400 or the handles 400 cannot slide up and down. Alternatively, the climbing points only include the handles 400 but do not include the pedals 300. In these implementations, a user does climb training with only hands or feet.
In the embodiment shown in FIG. 1, the vertical frame 200 is vertically arranged on the support 100 and tilts in a direction away from a user. The support 100 supports the vertical frame 200 to allow the vertical frame 200 to carry the weight of a human. The support 100 includes one base 101 and one inclined strut 102. The base 101 includes two parallel support rods 103 and two connecting rods 104 arranged between the two support rods 103. A support leg 105 is arranged at the bottom of each of two ends of each support rod 103. The support legs 105 are placed on the ground to support the climbing machine. A lower end of the vertical frame 200 is connected to the base 101. The inclined strut 102 is obliquely arranged behind the vertical frame 200. One end of the inclined strut 102 is connected to the middle of the vertical frame 200, and the other end is connected to the base 101, so that the vertical frame 200, the base 101, and the inclined strut 102 form a stable triangular structure.

A lower end of the support rod 103 is detachably connected to both the connecting rod 104 and the other support rod 103. The inclined strut 102 is hinged to the vertical frame 200. The detachable connection includes, but not limited to, a bolt-nut connection. The benefit of this preferred embodiment is that the space occupied to pack and store the climbing machine is reduced. Specifically, the vertical frame 200, the inclined strut 102, and the support rod 103 are detached from the connecting rod 104, and then the inclined strut 102 is rotated to fold the inclined strut 102 and the vertical frame 200. The vertical frame 200, the inclined strut 102, the support rod 103, and the connecting rod 104 are placed in the same direction, to form the state in FIG. 2.
In the embodiment shown in FIG. 1, further, a first housing 700 is arranged outside the vertical frame 200. The first housing 700 covers the one-way transmission mechanism 500. A second housing 800 is arranged behind the vertical frame 200. The second housing 800 covers the drive unit 600. The first housing 700 and the second housing 800 can provide protection, to prevent the one-way transmission mechanism 500 and the drive unit 600 from being exposed to avoid injuring a user.
In some other implementations, two or more climbing machines are integrated together to form one climbing machine for use by more than person at the same time. For example, two or more vertical frames 200 are arranged in parallel. Each vertical frame 200 separately corresponds to two pedals 300, two handles 400, and one one-way transmission mechanism 500. The transmission mechanism 500 share one drive unit 600. That is, the drive unit 600 can continuously drive the one-way transmission mechanism 500 to run in one direction to drive the two pedals 300 and the two handles 400 to move downward.
In some other implementations, the support 100 is not used to support the vertical frame 200. Instead, the vertical frame 200 may be leaned against a wall body. The lower end of the vertical frame 200 is connected to the ground, an upper end of the vertical frame 200 is connected to the wall body. For example, a bolt is used for fastening.
In the embodiment shown in FIG. 3, the pedals 300 and the handles 400 are respectively slidably arranged on two sides of the vertical frame 200. Specifically, the vertical frame 200 includes an upper section 201 and a lower section 202. One upper guiderail 203 extending along the upper section 201 is arranged on each of a left side and a right side of the upper section 201. One lower guiderail 204 extending along the lower section 202 is respectively arranged on each of a left side and a right side of the lower section 202.

The handle 400 includes a holding portion 401 and an extending portion 402 that is connected to the holding portion 401 and extends downward. A lower end of each extending portion 402 is connected to one slider 205. The two sliders 205 are respectively slidably connected to the two upper guiderails 203. The extending portions 402 are used for increasing the height of the holding portion 401. Even if the sliders 205 connected to the handles 400 slide to lower ends of the upper guiderails 203, the holding portions 401 can still remain at heights for easy holding. Four elongated through holes 701 extending in a slide direction of the pedals 300 and the handles 400 are reserved in a left side and a right side of the first housing 700. When the first housing 700 covers the vertical frame 200, the pedals 300 and the handles 400 are located outside the first housing 700. The sliders 205 are located inside the first housing 700. The length of the through hole 701 limits a slide stroke of the slider 205.
In the embodiment shown in FIG. 3, the pedal 300 includes a foot pedal portion 301 and a foot surface portion 302 connected to the foot pedal portion 301. During the use of the climbing machine, the foot of a user steps on the foot pedal portion 301, and the foot surface portion 302 covers the foot surface of the user. When the user lifts the foot, the pedal 300 can be driven to move upward. The two pedals 300 and the two handles 400 are further connected to the one-way transmission mechanism 500. Under the drive of the drive unit 600, the one-way transmission mechanism 500 can drive the pedals 300 and the handles 400 to move downward.

In the embodiment shown in FIG. 5, the transmission unit 503 is a sprocket transmission mechanism. That is, the transmission members 507 are gears 507, and the transfer member 506 is a chain 506. Each transmission unit 503 includes a closed chain 506 and two gears 507 respectively engaged at two ends of the chain 506. One gear 507 is connected to the one-way component 502. One gear 507 is arranged at an outer periphery of each of the four one-way components 502. The one-way component 502 transfers torque to the gear 507 in a single direction. A one-way bearing is used as an example. The gear 507 is sleeved on an outer periphery of an outer ring of the one-way bearing and is connected using a key 508. Referring to FIG. 6 to FIG. 8, the key 508 includes a cuboidal body 509. The body 509 has a first side surface 510 and a second side surface 511 opposite to the first side surface 510.

A third limiting portion 514 and a threaded hole 515 arranged spaced apart from the third limiting portion 514 are arranged on the second side surface 511. An axial key slot 516 is arranged at an inner edge of a gear 507 connected to the one-way bearing in a sleeving manner. In a structure connecting the gear 507 and the one-way bearing, the first side surface 510 faces the one-way bearing. An outer edge of the one-way bearing is accommodated between the first limiting portion 512 and the second limiting portion 513 to limit the axial movement of the key 508. The body 509 is arranged in the key slot 516. A bolt 517 is arranged in the threaded hole 515. The inner edge of the gear 507 is accommodated between the bolt 517 and the third limiting portion 514 to limit the axial movement of the gear 507.
Continuing to refer to FIG. 5, the transmission unit 503 extends in an extension direction of the vertical frame 200. Two transmission units 503 are respectively arranged on the left side and the right side of the upper section 201 of the vertical frame 200. The other two transmission units 503 are respectively arranged on the left side and the right side of the lower section 202 of the vertical frame 200. Specifically, one rotatable gear 507 is arranged on each of two sides of the top of the upper section 201. For example, the two gears 507 are respectively rotatably connected by a ball bearing to a first transverse shaft 518 transversely fastened at the top of the upper section 201. One chain 506 extending in an extension direction of the upper section 201 is further arranged on each of two sides of the upper section 201. An upper end of each chain 506 is engaged with the gear 507 arranged at the top of the upper section 201 and on the same side as the chain 506. A lower end of the chain 506 is engaged with the gear 507 on an outer periphery of the one-way component 502 on the same side. One rotatable gear 507 is arranged on each of two sides of the bottom of the lower section 202. For example, the two gears 507 are respectively rotatably connected by a ball bearing to a second transverse shaft 519 transversely fastened at the bottom of the lower section 202. One chain 506 extending in an extension direction of the lower section 202 is arranged on each of two sides of the lower section 202.

For example, the transmission unit 503 includes a closed steel rope and transmission rollers connected at two ends of the steel rope.
The slider 205 is fastened on the chain 506. The working principle of the one-way transmission mechanism 500 is described by using a one-way bearing as an example. In the embodiment shown in FIG. 5, each closed chain 506 includes a front section 520 slightly close to a user and a rear section 521 slightly far away from the user. The slider 205 is fastened on the front section 520. The drive unit 600 inputs torque into the rotation shaft 501, to make the rotation shaft 501 rotate counterclockwise. In this case, an inner ring and an outer ring of the one-way bearing are locked. Therefore, the one-way bearing drives the gear 507 to rotate counterclockwise, to make the chain 506 rotate counterclockwise, thereby driving the slider 205 to move downward. That is, the pedal 300 and the handle 400 connected to the slider 205 also move downward. When an upward force is applied to any pedal 300 or handle 400, an outer ring and an inner ring of a one-way bearing corresponding to the pedal 300 or the handle 400 are rotatable relative to each other. Therefore, the pedal 300 or the handle 400 can be lifted. In other implementations, the slider 205 may be connected to the rear section 521. In this case, the rotation shaft 501 should rotate clockwise, and the one-way bearing is configured to drive the gear 507 to rotate clockwise.
In some other implementations, referring to FIG. 11, a connection manner between the one-way component 502 and the transmission unit 503 may be that the one-way component 502 is adjacent to an outer edge of the transfer member 506 and is engaged with the transfer member 506 by a gear at the outer periphery of the one-way component 502.

The servo driver 611 is fastened to the rear side of the vertical frame 200, for example, arranged below the motor 601. The transmission assembly 603 is not limited to the form shown in FIG. 9. For example, a combination form of a gear and a chain may be changed. In other implementations, the transmission assembly 603 may further include a pulley mechanism, a sheave, or the like.
When the drive unit 600 is started, the one-way transmission mechanism 500 drives the two pedals 300 and the two handles 400 to move downward. When the pedals 300 and the handles 400 move to lower ends of corresponding chains 507, for example, the pedals 300 and the handles 400 lower to lower ends of corresponding through holes 701, the pedals 300 and the handles 400 are hindered and stop moving downward. During the use of the climbing machine in the present disclosure, a user uses two feet to step on the pedals 300 and use two hands to hold the handles 400. The two pedals 300 and the two handles 400 can move up and down independently, so that a plurality of climbing manners can be implemented, thereby improving the climbing experience. For example, the user may separately lift one hand or one foot, lift both hands, lift both feet, lift one hand and one foot on different sides or lift one hand and one foot on the same side. During use, the drive unit 600 provides power, and the one-way transmission mechanism 500 can drive the pedals 300 and the handles 400 to move downward. When the hands or feet of the user naturally fall on the handles 400 or the pedals 300, the hands or feet can lower along with the climbing points the handles 400 or the pedals 300. When the user lifts the hands or feet, through the characteristic of one-way transmission of the one-way transmission mechanism 500, corresponding handles 400 or pedals 300 can move upward, to provide the user with a feeling of climbing upward, thereby improving the climbing experience. During climbing, a climber climbs against the gravity, thereby improving the climbing experience for the user.
Disclosed in the embodiment shown in FIG. 9 is a powered climbing machine. During use, the drive unit 600 continuously provides power to the one-way transmission mechanism 500 to drive the pedals 300 and the handles 400 to lower. In some other implementations, an unpowered climbing machine is provided. Referring to FIG. 15, the unpowered climbing machine includes a damping device 1000. The damping device 1000 is arranged behind the vertical frame 200 and may be used for providing damping for the rotation of the rotation shaft 501. The damping device 1000 may be a magnetic powder brake. A conventional manner may be used between the magnetic powder brake and the rotation shaft 501 for transmission, for example, sprocket transmission. When a user touches climbing points 300, 400, for example, steps on the pedals 300 or holds the handles 400, under the weight of the body, the climbing points 300, 400 move downward. In this case, a transmissible relationship is provided between the transmission unit 503 and the one-way component 502. That is, the rotation shaft 501 is rotatable. However, under the action of the damping device 1000, the rotational speed of the rotation shaft 501 is small, so that the climbing points 300, 400 can slowly lower at a uniform speed under the weight of the body.
The foregoing descriptions are some implementation manners of the present application. It should be noted that for a person of ordinary skill in the art, several variations and improvements may further be made without departing from the concept of this application. These variations and improvements should also be deemed as falling within the scope of protection of this application.
