Description

Treadmill running belt

This creative department is related to the training of cardio-respiratory fitness equipment, especially a running belt of a treadmill, which has high surface softness, high durability and foot massage effect, thereby improving the user's exercise comfort and fitness effect, and Reduces sports injuries.

With the change of life style, people's opportunities for outdoor sports are reduced, and they are replaced by indoor sports. Among various fitness equipments, treadmills are generally popular among consumers because they can be used at home, and they can achieve both exercise and relaxation. Effect.

In order to increase the comfort of the treadmill, the current treadmill body usually has some shock absorption design. The shock absorption design on the common treadmill includes: setting elastic elements such as springs or rubber between the body and the running board (ie, the plate body located on the bottom of the running belt); and setting an elastic body at a predetermined position on the bottom of the body. Rubber to contact the ground. These shock-absorbing designs may increase the comfort of the treadmill, but the effect is still limited, so that users still need to wear sports shoes with good shock absorption when using these treadmills, in order to avoid too much vibration of the knee. force.

Moreover, the running belt of the treadmill for commercial households is mainly made of PVC plastic and antistatic yarn, and the surface thereof is hard and rough, so that the user must wear shoes when using the treadmill, otherwise use The soles of the feet will be excessively rubbed with the running belt and cause discomfort. This situation is quite inconvenient for most of the indoor and outdoor shoes in the current district. The reason is that the user has to waste because of the need to purchase sports shoes specially designed for indoor use, or the user wears outdoor sports shoes. And caused the indoor mess. The above two methods are quite inconvenient for the home treadmill user anyway.

In addition, the five fingers of the human foot can not be freely closed or opened when wearing shoes, whether it is standing, sitting, walking or even exercising, running. When you step, it will affect the blood circulation of the foot. Therefore, in recent years, more and more people like to "barefoot sports" in line with the natural movement laws of the human body; that is, to wear shoes without even wearing socks, and to allow the five fingers of the feet to stretch more naturally or Naturally combined according to the needs of exercise, in addition to promoting the blood circulation of the foot during exercise, the foot massage is achieved by the natural contact between the sole and the pedal.

In accordance with the above-mentioned "barefoot movement" trend, in the prior patent document, the Republic of China Announcement No. 360064 discloses a running belt of a treadmill having a towel material surface, by which the user can not use the softness of the surface layer of the towel material. Wear the treadmill with shoes.

Referring to FIG. 1 , the running belt 30 of the first embodiment provided by the present invention is used for Set on a treadmill. In this embodiment, the treadmill mainly comprises a frame 10, two rollers 20, a driving device (not shown), a control device (not shown), and the like.

The frame 10 has a base 12, a running board 14 is disposed on the base 12, and an armrest 16 is disposed on the base 12.

The two rollers 20 are pivotally disposed on the base 12 of the frame 10 and are respectively located on opposite sides of the running board 14 .

The driving device is mainly composed of a motor and a driving belt disposed on the base 12, wherein the driving belt is disposed around the output end of the motor and a roller 20, so that the motor can drive the roller 20 turns.

The control device is disposed on the armrest 16 at a position convenient for the user to control, and is electrically connected to the motor to control the operation of the motor.

The running belt 30 is formed in an endless belt shape and is disposed on the two rollers 20 , and a part thereof is adjacent to the running board 14 , whereby the part can be subjected to the running when the user steps on the running belt 30 . The plate 14 is supported.

Referring to FIG. 2 and FIG. 3 , the running belt 30 has a main belt body 32 , a soft layer 34 and a wear layer 36 . The main belt body 32 has an endless belt shape and is wound around the two rollers 20 .

In this embodiment, the main strip 32 has a cloth layer 321 and an intermediate layer 322 bonded to the cloth layer 321 . The intermediate layer 322 has a plurality of bumps 323 protruding from the surface.

The cloth layer 321 is used to limit the ductility of the main belt body 32. In the present embodiment, it is a non-woven fabric; in addition, the cloth layer 321 may be a woven fabric.

In the present embodiment, the bumps 323 are irregularly distributed on the surface of the intermediate layer 322, and each has an irregular shape. In addition, the bumps may also be regularly distributed on the surface of the intermediate layer 322, and may also be in a regular shape, such as a semi-spherical shape or a lateral semi-cylindrical shape.

In the present embodiment, the intermediate layer 322 is integrally formed of a polyvinyl chloride (PVC) material, which allows the main belt 32 to have better strength. Of course, in addition to this, the intermediate layer can also be made of other flexible materials such as rubber or nylon. Again, the convex The blocks can be made of different materials.

In the present embodiment, the soft layer 34 is an epoxy resin doped foaming agent, which is attached to the intermediate layer 322 and then heated to form a foam having a density smaller than that of the intermediate layer 322, that is, The ductility is preferably better than the intermediate layer 322, the hardness is smaller than the intermediate layer 322, and the surface thereof is correspondingly convex with respect to the bump 323 of the intermediate layer 322.
