Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a mobile platform used for physical exercise.

PROBLEMS SOLVED BY THE INVENTION AND MEANS FOR SOLVING THE PROBLEMS The mobile platform of the present invention can be used for the exercise of humans or, more particularly, animals, such as horses. . The present invention comprises a fixed platform constructed of a flat rigid material, a continuous belt extending over the upper running part supported by the fixed bluff 1 and the platform, and mounted between the fixed platform and the bell 1. It was loose! a first layer comprising a l1iI material and a polymer having a low effective IJJm and low compliance to facilitate movement of the belt relative to the fixed platform mounted adjacent to the first layer; It is proposed to obtain a mobile platform for use in physical exercise having a second layer consisting of:

Such a structure allows humans or animals, such as horses, to exercise, the first layer can effectively absorb the intermittent shocks that occur during use, and the second layer
The belt is easily movable relative to the first layer in a controlled manner. Preferably, the first layer is mounted directly on the rigid fixed platform and the second layer is mounted on the first layer in contact with the belt. However, if the first layer is mounted directly on the belt, i.e. forming an inner loose IMH with respect to the belt moving around the rollers, the belt 1- runs on the rollers; It is also contemplated that the second layer is mounted between the first layer and the rigid fixed platform, for example directly on the rigid fixed platform body.

Although a number of different materials can be used for the first layer, it is preferably comprised of a closed cell polymeric foam with high compliance. Also, rubber foam could be used instead of said material. The thickness of the first layer is 10 to 15 mm in order to sufficiently absorb shock.
, preferably 12 mm. Such a structure, among other things, protects the horse from flatulence and protects the horse's legs.

The belt may be restrained to move against some form of resistance, as in the case of a conventional foot device, but with the upper running portion of the belt moving over the platform. Preferably, devices are provided for driving the belts 1 to around the closed path, and it is advantageous if these drives are configured in such a way that the running speed of the belt can be adjusted.

For further movement of the human or animal, a rigid platform is advantageously pivoted on a support and a device for elevating the -h end of the rigid platform to tilt the rigid platform around the support. is provided. Therefore, a person or animal using the platform of the invention will essentially be running uphill.

The speed of movement of the platform can be adjusted by means of sensors and suitable control devices activated by the sensors.The structure of the invention therefore allows the horse to withstand movements between walking and full-on gatslobbing. It will be appreciated that the conditions for testing health and aptitude can be doubled: a combination of variable speed and variable adjustment of slope obtained by tilting the platform can be used to race horses. The invention can also be used to assess a horse's health and other conditions. For example, special Using the designed attachments 1 to 1, heart rate, electrocardiogram measurement results, hemotology counts (hae
The level of motalooy C0unt > and lactic acid can be monitored. As soon as a horse begins to walk, the functions of organs that are absolutely necessary for the maintenance of life become active, such as the horse's breathing and sweating becoming more intense, and at the same time changes in the body, such as body temperature and blood flow to the muscles. flow, heart rate and hemoglobin in the blood all increase. Experience has shown that a steady state phase is reached approximately 2 to 5 minutes after these values increase.

C1 Effects J3 and Embodiments In order to make the present invention easier to understand, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring first to FIG. 1, a moving platform, or treadle, for use in exercise is indicated generally at 10 and includes a frame 12 mounted on a support member 14 by a pivot 16. There is. As shown in FIG. 1, the left end of the moving platform can be raised and lowered using the lift jack 18.

Rollers 20 and 22 are mounted on the frame 12. A cloth reinforced rubber bell 1-24 is then threaded around rollers 20 and 22.

The rollers 20 are equipped with tension bearings 26 to keep the belt taut.

An electric motor 28 that drives a hydraulic pump 30 is mounted on the frame 12 . The hydraulic pump 30 functions to guide hydraulic oil from the oil reservoir 32 through the suction side filter 34. The hydraulic oil discharged from the hydraulic pump 30 is supplied to the hydraulic motor 36.

The hydraulic motor 36 allows precise and infinitely variable control of the speed of the rollers 22 and therefore of the belt 24.

below the upper running portion 25 of the belt 24 and the frame 1
Attached to 2 is a rigid fixed platform 38. Overlying the platform 38, as shown in FIG. 2, is a first layer 40 of a cushioning material, such as a highly compliant closed cell polymeric foam. Mounted on top of the first rI 40 is a second layer 42 comprised of a low friction, low compliance polymeric material. The second w 442 is disposed directly below the lower surface of the upper running portion 25 of the belt 24 . It will be appreciated that the first layer 40 can absorb the impact of a person or horse on the treadle 10 and that the second layer 42 facilitates movement of the belt 24 over the first layer 40.

In another embodiment of the apparatus shown in FIG.
is applied directly to the underside of belt 24 and moves with belt 24 around rollers 20° 22. In order to prevent wear, an inner belt (not shown) is provided inside the first layer 40 and the second layer 42, and the first layer 40 and the second layer 42 are inserted between the belt 24 and the inner belt. I can do it.

Although the second layer 42 is shown as being mounted on the top surface of the rigid stationary platform 38, the second layer 42 forms the bottom surface of the belt 24 below the first layer and any inner belts. It is also possible to configure it as follows. Again, the first layer is configured to absorb shock and the second layer facilitates movement of the belt relative to the platform.

To facilitate mounting the horse on the treadle, a ramp 44 is pivotally mounted to the frame 12 and the lateral position of the horse is controlled by two steel studs, one on each side. and a barrier (not shown) extends between these side walls 46 to restrict the front position of the horse. The lifting jack 18 can be actuated to tilt the platform upwardly, ie, in a clockwise direction. This lifting jack 18 can be operated manually or hydraulically controlled.
