The present invention relates to an exerciser, and more particularly to a mountain-climbing exerciser to train muscles of hands and legs of a user for simulating mountain-climbing.
Indoor exercisers can solve weather and location issues for exercising and are popular in this day. A conventional indoor exerciser, such as a mountain-climbing exerciser can train muscles of hands and legs of a user but is difficult to train synchronization coordination of the hands and legs of the user. Therefore, a convention mountain-climbing exerciser disclosed in U.S. Pat. No. 10,272,286, entitled “Climbing Exerciser” is provided to solve the aforementioned problem. The exerciser of the '286 patent comprises a frame having two tracks and a bracket. Two sliding units are disposed on the two tracks. Each sliding unit comprises a sliding rod, and a handle and a pedal combined with the sliding rod. The sliding rod is slidably disposed in a corresponding track, and the sliding rod is provided with a connecting block. A linking mechanism comprises two lower sprockets disposed at the lower ends of the two tracks, two upper sprockets disposed at the upper end of the bracket, two fixed pulleys disposed at the lower end of the bracket, a front chain wound on the lower sides of the two lower sprockets having two ends connected with the connecting block, two side chains wound on the upper sides of the two upper sprockets having one end connected with two connecting blocks, and a steel wire wound on the lower sides of the two fixed pulleys having two ends connected with the other ends of the two side chains. A magnetic-controlled damping device is disposed on the bracket and capable of being driven by the two upper sprockets. Through the aforementioned structure, the exerciser may simulate the rock climbing motion to achieve the purpose for training hands and feet coordination. However, the length of the bracket has to be longer than that of the handle to hold the whole handle inside, so the cost for manufacturing the conventional exerciser as the '286 patent is high. In addition, noise will generate due to the increasing contact area between the handle and the bracket. Furthermore, the magnetic-controlled damping device of the convention exerciser cannot provide a good damping effect and has a high cost for manufacturing.
To overcome the shortcomings, the present invention tends to provide a mountain-climbing exerciser to mitigate or obviate the aforementioned problems.
The main objective of the invention is to provide a mountain-climbing exerciser to provide an excellent damping effect and to reduce the cost for manufacturing.
The exerciser has a frame, a top cap, two handle units, two stepping boards, a wheel transmission mechanism, and a damping assembly. The frame has a frame base, two stands, two supporting rods, and a connection member. The stands are mounted on and protrude from the frame base.

The inserting rod is mounted through one of the inserting slots in the top cap, is inserted moveably in the inserting channel of a corresponding one of the stands, and has multiple rollers mounted rotatably on the inserting rod and a fixing base mounted on the inserting rod at a position near a bottom end of the inserting rod. The stepping boards are connected respectively with the two handle units, and each stepping board has a connection portion extending into the elongated hole in a corresponding one of the stands and connected with the inserting rod of a corresponding one of the handle units. The wheel transmission mechanism is mounted on the frame and has a driving axle, a driving wheel, two sprockets, two driving chains, a transmission wheel, a transmission pulley, and a driving belt. The driving axle is mounted rotatably on the two stands. The driving wheel is co-axially mounted around the driving axle. The sprockets are mounted respectively on two ends of the driving axle.

The driving axle 51 is mounted rotatably on the two stands 11. The driving wheel 50 is co-axially mounted around the driving axle 51. The two sprockets 52 are mounted respectively on two ends of the driving axle 51. The driving chains 53 are respectively mounted around and engaged with the two sprockets 52. Each driving chain 53 has a first end and a second end. The first end of the driving chain 53 is connected with connecting portion 36 of the fixing base 35 on one of the inserting rods 31. The first pulleys 56 are mounted rotatably on the two stands 11 of the frame 10 respectively.

Accordingly, while one of the inserting rods 31 is moved downward, the other inserting rod can be moved upward simultaneously. Thus, the exerciser can simulate the motion of rock or mountain climbing to train the hands and legs of a user.
The damping assembly B is mounted on the frame 10 and comprises a disk axle 72, a disk mount 71, a transmission belt 62, a magnetic disk 70, a magnetic base. The disk axle 72 is connected rotatably with the supporting rods 14 at a position below the transmission wheel 60. The disk mount 71 is co-axially mounted around the disk axle 72. The magnetic disk 70 is mounted co-axially around the sick mount 71 and has a periphery extending into a recess 86 defined in the magnetic base 80 in a non-contact manner. Preferably, the magnetic disk 70 is made of aluminum sliver material. The magnetic base 80 has multiple magnetic blocks 83 mounted on two sides of the recess 86 in the magnetic base 80. The magnetic base 80 has a first end connected pivotally with one of the connection member 15 with a pivotal axle 81 and a second end 82, so the magnetic base 80 can be pivoted relative to the connection member 15. A spring 85 has two ends connected respectively with the second end 82 of the magnetic base 80 and a hook 151 formed on the connection member 15. The transmission belt 62 is mounted around the transmission wheel 60 and the disk mount 71.

An adjusting cable 92 has a first end connected with the adjusting knob 90 and a second end connected with a cable-connection portion 84 on the second end 82 of the magnetic base 80. A plastic sleeve 91 is mounted around a part of the adjusting cable 92 to keep the adjusting cable 92 from abutting with the other components of the exerciser. Accordingly, the angle of the magnetic base 80 relative to the connection member 15 can be adjusted by rotating the adjusting knob 90 with the transmission of the adjusting cable 92. Therefore, the magnetic induction area between the magnetic blocks 83 in the recess 86 of the magnetic base 80 and the magnetic disk 70 can be changed, such that the damping effect provide by the damping assembly B can be adjusted. A strong damping effect provided by the damping assembly B is shown in
Preferably, wheel transmission mechanism 50 further comprises a driving idler wheel 64 abutting against the driving belt 64 for adjusting a tension of the driving belt 54.
Preferably, the damping assembly B further comprises a transmission idler wheel 63 abutting against the transmission belt 62 for adjusting a tension of the transmission belt 62. In addition, with the inserting channels 12 in the stands 11, the inserting rods 31 of the handle units 30 can be moved relative to the stands 11. Thus, the length of the stands 11 can be shortened, so the cost for the material of the stands 11 can be reduced. With the rollers 34 on the inserting rods 31, noise generated between the operation of the handle units 30 and the stands 11 can be reduced. Furthermore, the cost and time for manufacturing the damping assembly B can also be reduced.
