Artificial sports surface

A synthetic turf sports flooring product with a performance surface upon which sports can be played. The flooring product is formed from polymer fibres entangled to provide a sports surface layer which provides the performance surface, and substantially all of the polymer fibres of the sports surface layer are locked in position relative to the synthetic turf sports flooring product as a whole by the arrangement of fibres and contact between fibres in the mat. The fibres may be locked in position by entanglement, surface friction between fibres and/or inherent bonding of fibres in the synthetic turf sports flooring product. The product can provide a predictable playing surface which changes little with varying moisture and temperature changes during play, at least in part by avoiding the use of bonding chemicals in its structure. An underlay material of similar construction can be used in conjunction with the playing surface.

Plastics foam gymnasium mat - has one or more rows of air holes bored through to improve resilience and protective web on top

The plastics foam core for a gymnasium mat is made as a single layer with holes bored through it from end to end, instead of making it from two or more layers secured together by adhesive. This eliminates the disadvantage tha air is trapped inside, reducing its resilience. The holes may be round or some other shape, and may be in more than one row. Afterwards, the bored holes (2) may be filled with waste plastics foam material (4). An elastic web (3) may be fastened to the surface to act as protective layer.

Soft substance capable of changing color by temperature sensing for changing color by sensing user's body temperature

The present invention relates to a soft substance capable of changing color by temperature sensing, in which a soft substrate in light color is selected to form a first color and a normal ink of second color and a color-changing ink of third color are mixed to form an ink layer of fourth color, and the ink layer is laid on at least a first surface of the substrate. Thus, when the user's body contacts the ink layer portion of the substrate, the color-changing ink in the ink layer may be transformed to be transparent by the higher temperature of the user's body so that the fourth color of the ink layer may be sequentially transformed into the original color of the third color, the original color of the second color, which can be exhibited together with the first color of the substrate.

FLOOR PAD FOR VAULTING EXERCISES

The present invention concerns a floor pad of the type used while performing gymnastic exercises on a large floor area, for example 12 times 12 metres, where the floor pad covers this area. The floor pad is made up of at least one air-filled element and preferably of a plurality of air-filled elements, where the air-filled elements are fixed to each other by fixing means, e.g. by overlapping flanges with Velcro bands. By such a solution is i.a. achieved the advantage that a floor pad may readily and effortlessly be taken apart and emptied of air after use and then be folded and placed in boxes or packages. Another advantage of the floor pad according to the invention is that the space requirements are reduced by about 86% compared with prior art solutions. A further advantage is that the weight of the individual elements is not so great either.
