Description

Curved treadmill

This creation is about a fitness equipment, especially about a treadmill.

Some of the existing treadmills have a body, a running belt that is sleeved on the frame body, and a pedal that is fixed on the running belt. Therefore, when the user steps on the pedal, the two ends of the pedal are used. The roller and the frame collide and produce noise.

In addition, the roller and the frame are often made of a rigid material, so the impact sound is more obvious. In order to balance the material and strength, many components are made of a hollow tube body, and a hollow chamber forms a resonance chamber, and each step taken by the user when using the treadmill. The sound will be amplified by the tube, which will cause annoying noise.

At the same time, in the existing treadmill, in order to prevent the pedal from being displaced laterally due to the lateral force, a long groove-shaped track is arranged on the frame body for the pedal roller to move in the track, so that the moving path of the roller can be restricted. However, when the roller is displaced left and right in the track, it collides with the side wall of the track, and no small noise is emitted.

In view of this, it is an urgent problem to be solved in the industry to propose a better improvement solution.

The main purpose of this creation is to propose a curved treadmill that effectively reduces the noise generated during use.

In order to achieve the above object, the arc treadmill proposed by the present invention has: a frame body having: a support frame; and two arc-shaped guide rails, which are downwardly concave arcs, and are respectively located on both sides of the support frame; a plurality of cushioning pads respectively fixed on the upper side of the two curved rails; a plurality of guiding wheels disposed at the front end and the rear end of the supporting frame; and a plurality of positioning wheels disposed at the front end of the supporting frame Between the rear ends; an armrest group fixed to the two sides of the frame body and having an armrest; and a running belt set which is sleeved on the frame body and has at least one connecting belt which is sleeved on The guide wheels, and the side edges thereof abut or are adjacent to the positioning wheels; and a plurality of pedals fixed to the at least one connecting belt, and the pedals are adjacent to each other and are selectively slid downwardly Rely on the two cushions.

Therefore, the advantage of the present invention is that the cushion is provided on the curved guide rail to achieve the effect of shock absorption and noise reduction. In addition, the connecting belt is abutted against the positioning wheel, and the connecting belt can be laterally deformed and smoothly used. The ground is bypassed on the support frame and does not emit noise.

In the curved treadmill as described above, each of the pedals of the running belt set has: a plate body; two spacers, the two sides of which are respectively fixed on the plate body and the at least one connecting belt; and two rollers, The two are fixed to the two ends of the plate body and selectively abut against the two cushions fixed on the two curved guide rails.

In the arc treadmill as described above, the plate body of each of the pedals of the running belt group has: a plate frame, and the two gaskets and the two rollers are fixed to the plate frame; A pedal piece that is nested with the plate frame.

In the curved treadmill as described above, the two rollers are made of polyurethane.

In the arc treadmill as described above, the frame body further has: two linear guide rails respectively located on two sides of the support frame below the two curved guide rails; and two cushions respectively fixed to the two straight lines The upper side of the rail; the two rollers selectively abut downward against the two cushions fixed on the two linear guides.

In the curved treadmill as described above, each of the curved guide rails of the frame body is a single piece.

Please refer to Figure 1 first. The present application proposes a curved treadmill having a body 10, a handrail set 20, and a running belt set 30.

Then please refer to Figure 2. The frame body 10 has a support frame 11, two curved guide rails 12, two linear guide rails 13, four cushion pads 14, a plurality of guide wheels 15, and a plurality of positioning wheels 16.

The curved guide rail 12 is spaced apart from the linear guide rail 13 . The curved guide rails 12 are downwardly concave curved sheets and are respectively located on both sides of the support frame 11. The linear guide 13 is a tubular body which is respectively located on both sides of the support frame 11 below the two curved guide rails 12. The two cushions 14 of the four cushions 14 are respectively fixed on the upper side of the two curved rails 12, and the other two cushions 14 are respectively fixed on the upper sides of the two linear guides 13.

A plurality of guide wheels 15 are disposed at the front end and the rear end of the support frame 11. In the present embodiment, there are four guide wheels 15 , wherein the two guide wheels 15 are arranged side by side and spaced apart from the front end of the support frame 11 , and the other two guide wheels 15 are arranged side by side and spaced apart from the rear end of the support frame 11 . A plurality of positioning wheels 16 are disposed between the front end and the rear end of the support frame 11. In the present embodiment, the positioning wheels 16 are arranged in two rows along the length direction of the support frame 11 between the two guide wheels 15.

The armrest group 20 is fixed on both sides of the frame body 10 and has an armrest.

Please refer to Figures 2, 3A and 3B. The running belt set 30 is sleeved on the frame body 10, specifically, the curved guide rail 12, the linear guide rail 13 and the plurality of guiding wheels 15 which are sleeved on the frame body 10. The running belt set 30 has at least one connecting belt 31 and a plurality of pedals 32. In this embodiment, there are two connecting straps 31. The connecting straps 31 are sleeved on the guiding wheel 15, and the side edges thereof abut or are adjacent to one of the rows of positioning wheels 16.

Please refer to Figure 4 to Figure 6 together. The pedals 32 are fixed to the connecting straps 31, and the pedals 32 abut each other side by side and abut against the cushion pad 14. Specifically, each of the pedals 32 in the embodiment has a plate body 321, two spacers 322, and two rollers 323.

The plate body 321 is fixed to the connecting belt 31 side by side, and the plate body 321 has a plate frame 3211 and a pedal piece 3212. The cross section of the plate frame 3211 is U-shaped with the opening facing upward, and the pedal piece 3212 and the plate frame 3211 are sleeved with each other. The upper side of the gasket 322 is fixed to the lower side of the plate frame 3211, and the lower side of the gasket 322 is fixed to the connecting belt 31. In other words, the plate frame 3211 of the plate body 321 is fixed to the connecting belt 31 through the spacer 322.

The two rollers 323 are respectively fixed to the two ends of the plate frame 3211 of the plate body 321 and selectively abut against the two cushion pads 14 fixed on the two curved guide rails 12 or the two linear guide rails 13. The material of the roller 323 is polyurethane (commonly known as PU material).

Through the above structure, when the user uses the creation, the user steps on the pedal 32, and the two rollers 323 of the pedal 32 will abut against the two cushions 14 on the two curved guide rails 12, and the cushion pad 14 and the roller 323 will be The shock absorbing effect can be provided, so that the pedal 32 and the curved guide rail 12 do not emit noise due to collision. In addition, unlike the tubular linear guide 13, the curved guide rail 12 has a plate shape, so that no cavity in the curved guide rail 12 resonates, and the collision sound generated when the user steps on the pedal 32 is not blocked by the curved guide rail 12. amplification. By the side edges of the connecting belt 31 abutting against the row of positioning wheels 16, when the user exerts uneven force during the movement of the creation, the connecting belt 31 is still not laterally deformed and can maintain a straight line.

In summary, the present invention has a plate shape on the curved guide rail 12 and is provided with a cushion pad 14 to achieve the effect of shock absorption and noise reduction. In addition, the connection belt 31 abuts against the positioning wheel 16 and is connected during use. The belt 31 does not laterally deform and smoothly wraps around the support frame 11 without causing noise.
