Definitions

• the invention relates to a shoe with two or more rotatable rollers which are arranged on one or more axes, the axes being oriented essentially transversely to the longitudinal direction of the shoes or transversely to the running direction.
• Roller skates are known from the prior art, which can either be detachably connected to ordinary shoes by means of a frame which can be sounded, or which are screwed to the shoes by a frame which rests on the underside of the shoe sole.
• the so-called inline skates could be seen as a further development of the second version. These are shoes that are firmly or detachably connected on the underside with a series of “in line” rollers. Both inline skates and roller skates have in common that you can only ride.
• Shoes in which two or more rollers are arranged one behind the other in the direction of movement are particularly widespread.
• the advantage of this arrangement is that the user learns to stand safely on the roller skates in a short time even without lengthy practice. If at least two rollers are arranged next to one another as seen in the direction of travel and - as mentioned above - at least two rollers are also arranged one behind the other, a stable stand is possible.
• Roller skate users the ability to change the direction of travel of both roller adjust the shoes slightly outwards from the main direction of movement so that both roller skates move away from each other.
• the user must exert muscle forces that spread his legs and thereby exert a force on the roller skates that is oriented obliquely to their current direction of travel. The portion of this force that is oriented in the direction of travel accelerates the roller skates and thereby also the user standing on them.
• the same method can be used as for accelerating with different driving directions for the left and right shoes. If z. B. move the shoes away from each other, the user must counteract the spreading exerted by the roller skates on his legs with muscle power.
• the object of the invention consists in the construction of a shoe which can be used both as a driving and playing device and as a fitness device and which, in addition to the moving movement, also permits a walking or running movement and enables rapid braking.
• the shoe according to the invention can be changed in a very short time without a special tool, even by inexperienced users, so that the rollers touching the ground when the heel area is lowered can be raised to such an extent that they no longer touch the ground during a normal walking or running movement.

• the main idea of the invention is that the wearer of a left-hand and right-hand shoe according to the invention, each have the features described in the claims, can gain momentum through an introductory running movement and can convert this momentum into a moving movement by shifting weight towards the heel area.
• the user can therefore achieve the desired speed by walking and / or running (only on the front area of the shoes). Then he lowers the rear area of the shoes and lifts the front area of the shoes. In this state, only the rollers of the shoe according to the invention touch the surface.

• shoes according to the invention lowers the front area of the shoes onto the surface. As soon as the surface touches the ground, the user must suddenly change to a running or walking movement corresponding to the speed. This transition requires a certain amount of training to keep your balance even in the transition phase. For this reason, it is pointed out that shoes according to the invention with firmly mounted rollers should not be used in means of transport such as buses and trains, on stairs or in busy areas such as pedestrian zones or rows of shops.
• This recommendation is intended especially for completely inexperienced or only inexperienced users.

• To stabilize the position while driving die the legs, as seen in the direction of travel, are offset from one another. Braking takes place by shifting weight from the heel area of the shoe sole in the direction of the soccer ball until the shoe sole, which is free in this area, ie not provided with wheels, comes into contact with the solid surface.
• a quick braking is also possible by tipping the heel edge of a shoe. The angle of attack during this braking maneuver depends on the position of the axle, ie the further it is from the rear shoulder edge, the smaller the backward movement of the shoe required for braking.
• Driving with the shoes according to the invention strains muscles that are not trained during normal walking or skating. This particularly affects the muscle areas of the thighs, calves, abdomen and back. This makes the shoes suitable in principle for use in leisure sports, such as. B. for

Viewed from the side, the axes of rotation can then be dimensioned very flat, so that they only need a very flat recess in the sole of the shoe. Due to their large area, such semiaxes are pressed against the sole of the shoe. The large diameter of the axis of rotation enables it to be made from the same material as the sole of the shoe in a mold. To prevent the unloaded semiaxis from falling off the sole, it is sufficient to form a bead at the end of the semiaxis in the case of partially flexible sole material, over which the semiaxis is pushed onto the axis of rotation.

• the second receiving device is arranged so that the roller attached to it is in the running position, the lower edge of the roller 2 is therefore above the underside of the shoe sole.
• This second holding device can be arranged anywhere on the outside of the shoe. So on the side near the mount that is used for the driving position. Or in the front area, elsewhere on the sides or in the rear area near the heel. If the shoe is equipped with 2 wheels, the respective holding devices for the running position can, for example, both be arranged on one side. preferably on the outside of the shoe so as not to bump into the other shoe. Or one shot is positioned on the tip, the other on the heel. Or both recordings are arranged one above the other on the heel.
• the receiving device can also be integrated into the underside of the shoe sole.
• a corresponding recess must be provided in the shoe sole, into which the roll fits.
• the advantage of this position is that the rollers are not visible from the outside in the running position. So that the recess does not become dirty, it can be closed with a removable cover.
• the lid should be attached to the sole of the shoe with a flexible strap to protect against loss or open against spring pressure.
• the holder When the rollers are in the driving position, the holder must be able to withstand the forces that occur when driving and transmit them to the shoe. In the running position of the rollers, the holder only has to bear the weight of the rollers themselves.
• the simplest form of the holder is an internal thread in the shoe sole or in the shoe, into which a screw fits as a counterpart.
• An advantageous feature is the (loss-proof) fastening of the screw to the roller.
• the invention prefers that the actuating elements on the head of the screw - similar to a wing nut - have sufficiently large actuating surfaces on the largest possible diameter.
• the invention prefers one
• Bayonet lock instead of the screw.
• the bayonet catch acts like a screw, but with different pitches.
• the slope is first reduced to zero and then negative for a short area. This reduces the risk of unintentional loosening.
• lever articulated to the receiving device which can be folded down transversely to the axis of rotation of the roller. When stretched, the lever fits through the opening of the roller. After folding down, a tension spring presses the lever on the roller and thereby holds it in this position.
• the pivot point of the tension spring can only be as far from the pivot point of the lever as the size of the opening in the roller allows. However, the lever itself is longer. This reduces the actuation force when unlocking.
