Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable surface device, particularly a motor-driven movable surface for physical exercise and illumination exercises on which a person riding on the surface is forced to walk, run or similar movements. Regarding equipment.

Available in various types, usually consisting of endless belts, etc.
Surface devices have already been proposed.

Generally, in devices of this type, a wide endless belt made of rubber is supported, for example over its entire width, by stationary supports in order to prevent bending due to the weight of the user. In such an example, since the rubber movable belt engages with the support surface, a slight friction occurs between the rubber belt and the support surface, and a strong driving force is required. Additionally, rubber belts inevitably wear out due to friction between them and the support. Furthermore, the feeling of stepping on the rubber belt is not comfortable.

This is due to the fact that the belt is rigid, which limits the thickness of the rubber belt.

There are also belts in which the entire width of the belt is supported by a rotating support row 2, etc., but in such belts, the elasticity on the roller support portion is poor, causing discomfort when used for long periods of time. There are drawbacks.

The object of the invention is to provide a comfortable jumping feeling when stepping or jumping, requiring only a small driving force, having a low noise level during operation, and without being subjected to excessive stress due to bending or bending. An object of the present invention is to provide a movable surface device.

The movable surface device for physical exercise and training of the present invention includes a pair of drums, an endless belt suspended on the drums and running on an upper running part and a lower running part, and a plurality of belts fixed to the belt. It is characterized by comprising a foot slat and an elastic buffer support that elastically supports the foot slat at both ends thereof.

Next, specific examples of the present invention will be described with reference to the drawings.

In FIG. 1 1 is a movable surface driven by a motor 33 (FIGS. 2 and 3).

A person standing on this movable surface 1 must walk or run if he wishes to remain in his position. 2 is a no-using, 3 is a support rod, and one of the support rods 3 has a control device f.
A fItC is attached to control the operation of the motor 33, such as starting, stopping and speed of the motor.

In Figure 2, 36.37 is a frame and this frame 3
Two actuating drums 10 are rotatably supported at the tips of the actuators 7 . The drum 10 has an outer peripheral surface formed with teeth or ribs.

Two endless ribbed belts 5 (FIG. 4) having teeth or ribs 7 on their inner peripheral surfaces engage the drum 10, thereby causing the two ribbed belts 5 to move in the direction indicated by arrow A in FIG. It moves smoothly in the direction of movement indicated by . The ribbed belt 5 is flexible and is made of rubber or a suitable flexible rubber material. One of the drums 10 is driven by a motor 33, preferably via a reduction gearing and a drive belt 34 (FIG. 3). The ends 38 of a group of dark slats 4 forming the movable surface 1 are fixed to the ribbed belt 5 by rivets 9 (FIG. 4).
.

The slats 4 are preferably made of lightweight metal, such as aluminum, and extend in a direction transverse to the direction of travel of the movable surface, as indicated by arrow A. The slat 4 has an approximately letter-shaped cross section and is provided with a central web 8.

The central web 8 does not extend to the ends of the slats 4.

The width B of the connecting end 38 of the slat 4 to the belt 5 forms a substantially rectangular end having a width B and a length L, which is smaller than the width of the slat 4. (Figure 4). Further, the offset amount of the web 8 (the length retracted from the end portion 38) is larger than the length L. The distance between adjacent tread slats 4 is
It is chosen such that a small spacing or gap remains between the slats 4, just enough to prevent interference of adjacent slats during movement. On the upper surface of the slat 4,
A shock reducing cover 16 is covered on it so that when a person stands on it, it feels soft and allows a comfortable and obedient walk (see Figs. 5, 6, and 7). In the figure, this cover 16 is omitted).

The material of the cover 16 can be rubber, corky material, high density sponge rubber, plastic foam, artificial turf surface, outdoor or indoor carpet, especially with a rubber backing.

In order to prevent the belt 5 from bending when a load is applied to the belt 5 when a person walks, a layer 17 made of rubber or other elastic material and having a yielding property is provided on the lower surface of the tread slat 4. The stepped slats 4 are supported at each end by a group of support rows 212 arranged adjacent to each other. These support rollers are rotatable about a fixed axis. The support roller supports the upper run of the movable surface 1 formed by said slats 4 and is present over the entire working length of the support surface 1 between at least two drums 10.

The diameter of roller 12 is smaller than the diameter of drum 10.

As clearly shown in FIG. 7, support roller 12 is rotatably supported in U-shaped channel 20 via screws or bolts 21. As shown in FIG. The U-shaped channel 20 is carried by an angle or channel rail 32 VC secured to the frame of the device.

The connection between the U-shaped channel 20 and the rail 32 is preferably made by screws 28, although any other suitable connection means may be used, such as welding. The support roller 12 is
For example, the needle bearing is supported by a low friction bearing such as a ball bearing (FIG. 5). However, it is also possible to use sleeve bearings that operate with low friction on the bolt 21. The distance between the upper surface of the support roller 12 and the lower surface 14 of the elastic MiL shock layer 17 applied to the underside of the tread slat 4 is, for example, approximately 14 cr when no load is applied to the movable surface 1.
The distance is selected to be as small as t1. When a load is applied, for example by a user riding on the tread slat 4, the lower surface 14 engages the support roller 12.

In this case, the bolts 21 of the support roller 12 are arranged in a fixed position on the frame, and the force applied to the tread slat 4 is received by the support roller 12, so that the belt 5
will not bend or droop. In this way, the movable surface 1 is substantially flat while retaining some elasticity, resembling a natural soft grass or other soft surface competition track.

FIG. 6 shows another embodiment of the invention, in which instead of supporting rows 212, each bolt 21' is supported by a very large number of bolts 21' disposed closely adjacent to each other. A small support roller 12' is used. The rollers are arranged such that no matter what position the slat 4 is in, at least two rollers 12' are in supporting engagement with each slat. As shown, an arrangement of three rollers mating with one slat 4 is preferred.

8 and 9 show another specific example of the structure for moving the foot slat 4. FIG. It should be noted that the elements already described are indicated by the same reference numerals, and a re-description of the 7v element will be omitted.

In this embodiment, instead of using the two transversely ribbed belts 5, a central endless belt 35 is used which is suspended in a loop around the two end drums 25. Preferably, belt 35 is made from rubber. This belt 35 is relatively wide and comprises an angular element 23 secured, for example by riveting, screwing or the like, to the central web 8 of the tread slat 4. The points of connection of the tread slats 4 to the belt 35 should be as far apart as possible from each other so that the slats 4 are guided correctly perpendicular to their running direction without distortion. The central web 8 of the tread slat 4 is offset inwardly at both end portions and supported by support rollers 12 (
or 12'). drum 25
is provided with a laterally projecting rim 30 for guiding the belt 35 and preventing its lateral displacement. The drum 25 is supported by ball bearings 27 on a central shaft 26 fixed to the frame structure or, as in the illustrated embodiment, to the side wall of the housing 2 . The tread slats 4 are slightly shorter than the spacing between the side walls of the housing 2, and a small side gap is formed between the tread slat ends and the housing side walls. However, the width of the belt 350 is preferably much shorter than the length of the slat 4, and is preferably about one third of the length of the slat.

The moving surface device can be in a horizontal position or alternatively in a slightly tilted orientation. The use of rubber or similar elastic materials provides quieter operation. As an example of typical device dimensions, the overall length may be approximately 2 m, the width ``/4 m'' and the height from the ground to the upper running part of the moving surface approximately 1/4 H. Control element C A distance counter can be provided in the box to display, for example, the distance the user has run or walked while training with the device.

As described above, according to the present invention, the device can be used for a long time without causing discomfort to the user's feet, and can evenly and uniformly move the movable surface 1 with less friction during load. There are big profits that can be made.
