ROLLER-SKATES/SNEAKERS WITH SEPARABLE WHEELS

Abstract

Roller-skates/sneakers with two pairs of separable wheels, by which the problem of their alternative adjusting for walking or roller-skating is solved, and which are at the same time safe, maneuverable, practical and simple to manufacture. The roller-skates consist of sneakers, which are laced with laces, an insole and two pairs of wheels separably fixed in the insole. The insole, which follows the shape of the foot and contains the front and rear axle and forms the load-bearing construction, is built into the lower part of the sneaker inside the sole. The wheel consists out of the middle plate lined with silicone rubber, an interchangeable mask, two bearings on the rims of central hollow part of the wheel, as well as two washers made of steel with two lids on the side of the wheel facing the sneaker.

DETAILED DESCRIPTION

[0024] According to this invention and FIGS. 1 through 8, the roller-skates 1 roughly consist of sneakers 2 (for the purpose of rationality, only the right sneaker is shown, the left one is its reflection in the mirror), insole 10 and two pairs of wheels 4, which are distributed so that two wheels 4 are in the front of the sneaker 2 and two wheels 4 are in the back of the sneaker 2.

[0025] The sneaker 2, according to FIGS. 1 through 4, consists of the following basic parts: upper side 6 of the sneaker 2, visible from its outer view on FIG. 1, made of fabric or any other relatively elastic material, tongue 7′ of the sneaker 2 on which the laces 3 rest, as well as the inner side 7 of the sneaker 2, visible from above on FIG. 3. As shown in FIGS. 5-7, upper side 6 of the sneaker 2 and the inner side 7 are firmly connected to the tongue 7′ at one end, over which the laces 3 are laced, while, on the other end, the sole 6′, in which the insole 10 is inserted, is connected to the upper side 6 and the inner side 7. Within the sole 6′ of the sneaker 2, the insole 10 is inserted through which pass the front axle 9 and the rear axle 8, whereby to the insole 10, on one end, the rear axle 8 is firmly connected, whereby the ends of the rear axle 8.1 and 8.2 are in the same axis, while the front axle is firmly connected to the sole 10 on the other end, so that the ends 9.1 and 9.2 of the front axle 9 are moved one to the other in value a in a plane parallel to the surface. The axle 8, on the outside, is shaped in the form of the elongated cuboid. On its lateral sides 8.4 and 8.5 on both of its ends 8.1. and 8.2 the holes are drilled in which screws 5 are inserted and screwed. Ends 9.1 and 9.2 of the front axle 9, on the outside, are shaped in the form of elongated cuboid, whereby its central part 9.3 has the shape of parallelepiped. It is essential to point out that the central part 9.3 is made as one piece together with its ends 9.1. and 9.2. whose vertices are identical. On its lateral sides 9.4 and 9.5 on both of its ends 9.1. and 9.2 the holes are drilled in which screws 5 are inserted and screwed.

[0026] The insole 10 is a construction made of composite materials, but for the purpose of the insole's 10 manufacturing, any other suitable material could also be used. Through the lower side of sneaker 2, at the level of the insole 10 and through it pass front axle 9 and rear axle 8, which can be clearly observed in FIGS. 4 through 7. On the upper, outer side of the sneaker 2, in accordance with FIGS. 1 and 3, there are adjustable laces 3 which, when tightened and relaxed, primarily allow for the sneaker 2 to be laced, as well as to adjust the level of stability and comfort for the user.

[0027] Wheel 4 consists of the middle plate 16, made out of solid material coated with silicon ring 12, where the interchangeable mask 11 of circular shape, as can be observed in FIG. 8 as well as the A-A cross-section in FIG. 10, rests on both sides of the wheel 4. Through the central hollow part of the front wheel 4 passes the screw 5 which is to be screwed in the front axle 9, whereby through the central part of the rear wheel 4 passes the screw 5 which is to be screwed in the rear axle 8. Front axle 9 and rear axle 8 are integral parts of the sneaker 2, or rather its sole 6′, to which they are fixed and as such, they allow for front and back wheels 4 to be held. Front and back wheels 4 can be fixed to and removed from sneaker 2 by the means of screws 5, which are fixed to the front axle 9 and rear axle 8 with the standard tools. Each of the wheels 4 is modular, which makes them easy to mount so the roller-skates 1 could be used for the purpose of skating, as well as easy to remove so they could be used for the purpose of walking in the sneakers 2 without the wheels 4. On the rims of the central hollow part of the wheel 4, which passes through the middle plate 16 of the wheel, there are two bearings 13 of circular shape, while on the side of the wheel 4, which is turned towards the sneaker 2, there are two steel washers 15, whereby around the bearing 13 and part of the middle plate 16, there are two lids 14. The middle plate 16 is coated with the silicon ring 12 along the entire surface of the part of the wheel 4 which comes in contact with the ground used for moving around, according to FIGS. 8 through 10. The axes of the front pair of wheels 4 are moved one to another for value a, whereby the moving is made in the plane parallel to the surface. Front wheel 4 from the inner side of the sneaker 2, at the thumb's place, in relation to the front wheel 4 on the outer side of sneaker 2, in the place of the little toe. The disposition was carried out for value a in a plane parallel to the ground, as shown in FIG. 7. Unlike the front pair of wheels 4, the axes of the back pair of wheels 4 are coaxial, i.e. at the same distance from the back end of the sneaker 2 lengthwise. Each of the sneakers 2 has one front axle 9 and one rear axle 8.

[0028] Sole 6′ of the sneaker 2 is its sturdy, stable part, placed as a bottom of the sneaker 2 and cut so that in its inner side, an insole 10 which follows the shape of the foot, can fit it, including the axles 9,8 which are fixed and on which the wheels 4 can be mounted by the means of screws 5. Tongue 7′ of sneaker 2 is made out of fabric and together with the laces 3 it allows for a flexible and comfortable motion, where the tightness of the laces 3 is adjustable according to the needs of each individual user. In regards to the functioning, bearing in mind all the previously mentioned elements as well as their interrelation, there is no need for further description on how the invention is practically used. This is due to the fact that the detailed description of the invention, as well as its purpose, allow for an easy deduction of the manner in which the invention can be applied.
