Under Roller skate is related to the present invention an inline skate, ice skate, roller skate and the like in the to understand the broadest sense. The invention further relates to a Pedal pedal with a fastening device for fastening a Shoes in the forefoot section on the foot pedal, taking under Pedal, any step for a crank, i.e. for example a bicycle pedal or the like is to be understood. Moreover The invention relates to a shoe for the invention Rolling / sliding unit or the foot pedal according to the invention.

There are already inline skates especially for urban Area known, which have a rolling unit, the simple way with a shoe can be connected to one hand the fast way of getting around with the inline skates to be able to use, and on the other hand a quick "changeover" to allow for normal shoes.

An inline skate is already shown in WO 98/06467, at to which a shoe connected to the roller unit has a special has comparatively hard assembly unit, which enables will that the required stability of the connection between Shoe and inline skate even with just one fastener between shoe and inline skate.

On the other hand, a shoe is from DE 296 08 296 U1 detachable lower part known, which has a projection in the toe area, and hook-shaped fasteners in the heel area for connection with a rolling unit. The fastening projection in the However, toe area is without when using the shoe Roll unit obstructive.

From US 5 797 608 A, the attachment of a Known shoe with a gliding unit in the forefoot section a stationary hook is provided that is vertical to the longitudinal axis of the shoe arranged bolt in the closed position embraces. For fastening the shoe on the gliding unit or to release the attachment is a swiveling lever with a wedge-shaped locking hook in the midfoot or Heel section provided in a closed position in a wedge-shaped recess on the underside of the sole in the midfoot or heel section engages. For attachment or detachment the attachment must either an actuator for Moving the lever or a locking bolt provided be because of the wedge-shaped design of the locking hook no automatic locking can take place.

Various fastening devices are available for pedal pedals known, which apart from holding loops (so-called clips) also elaborate snap connections that establish a firm connection include.

The aim of the present invention is now a rolling / sliding unit or to create a foot pedal, which (s) on simple and quickly and automatically connected to a shoe can be without a special locking device must be operated manually. In addition, a structurally simple and created a low number of parts connection which one for a good driving feeling or good pedaling behavior ensures the required stability of the connection and an automatic readjustment of the fixation enables. Of Furthermore, one for attachment to the rolling / sliding unit or the foot pedal suitable shoe can be created that on simple and quick way on the rolling / sliding unit or the Pedal pedal can be mounted, and regarding walking comfort if possible not different from a conventional street shoe.

This goal is achieved with a rolling / sliding unit according to the invention of the type mentioned at the outset obtained as that Fastening device in the forefoot section at least one around one essentially perpendicular to the longitudinal axis of the rolling / sliding unit arranged axis pivoted pivot lever is provided which is by means of a spring, preferably a torsion spring, held in an open position in the unloaded state is in which the free end of the pivot lever of the Mounting plate is spaced, and the for transferring into its pivoted closed position in a recess in the Bottom of the sole of the shoe is insertable in the for fastening a substantially perpendicular to the longitudinal axis of the shoe arranged bolt is provided in the closed position is gripped by the pivot lever.

With the help of the swivel lever located in the forefoot area becomes a structurally simple, elegant and also visually attractive Fastening device created that is reliable Fixation of the shoe on the rolling / sliding unit guaranteed. In addition, a special advantage is provided in the toe area of the shoe to hook into an eyelet the roll / slide unit is not required as only one Recess on the bottom of the sole of the shoe for fastening is sufficient which, when using the shoe without the Rolling / sliding unit is not distracting and also the look of the Shoe not adversely affected. Through the swivel lever causes an automatic fixation of the shoe, being independent how far the swivel lever into the recess on the shoe sole protrudes, a fixation is guaranteed, provided a movement in the longitudinal direction of the shoe relative to the rolling / sliding unit is prevented. This can be done with the help of any known ones Fixing systems, such as a spring clip or the like, take place in the midfoot or heel area, i.e. the fixation in the forefoot section is independent of the type of fixation in the midfoot or heel area. It is also advantageous that with changes on the underside of the sole (e.g. if dirt or the like falls out between the mounting plate and the sole) the fixing system with the swivel lever automatically readjusted by penetrating the swivel lever deeper into the recess, so that even if the sole of the shoe is worn, it is reliable Fixation is guaranteed.

For a reliable fastening of the shoe on the Rolling / sliding unit and an even fixation of the shoe with side loads, it is advantageous if a swivel lever essentially in the center plane of the mounting plate is arranged.

For a particularly stable fixation of the shoe when two spaced-apart pivot levers in the transverse direction the mounting plate arranged in the forefoot section are.

If the connecting line of the pivot axis of the pivot lever with the freely projecting end of the swivel lever in the open position an angle of less than 80 °, preferably of approximately 60 °, with the plane defined by the mounting plate, preferably towards the midfoot or heel section, will reliably block the pivot lever in prevents a position perpendicular to the mounting plate and the swivel lever swivels when the shoe is placed on the Mounting plate of the rolling / sliding unit reliably in its Closed position.

To insert the pivot lever into a recess on the To lighten the bottom of the sole of the shoe, it is beneficial if the swivel lever on its facing away from the mounting plate Side a surface convex to the mounting plate having.

When the swivel lever on its facing the mounting plate Side at least one projection to rest on the bolt has a certain amount of friction between the Projection and a fastener in the shoe, creating the user signals the closing of the fastening device becomes.

To insert the pivot lever into a recess to simplify the bottom of the sole of the shoe, it is convenient if the swivel lever tapers towards its free end, has tongue-like shape. It also becomes a Self-centering of the shoe achieved on the mounting plate.

For easy mounting of the swivel lever on the mounting plate it is convenient if the swivel lever on one with the mounting plate firmly connected bearing part pivotally mounted is. This results in a structurally simple, stable Fixation if the bearing part has a mounting flange attached to the mounting plate by means of a rivet connection is. Around the bearing part at least partially in the mounting plate to sink, it is favorable if the bearing part in one Recess is received in the mounting plate.

Alternatively, the bearing part can also be easily in Be kept in the vertical direction in the recess when the bearing part is at least partially covered by a holding plate.

For a reliable grip around a fastener of the shoe, e.g. a bolt in the recess in the bottom of the sole, and for a play-free fixation of the Shoe on the mounting plate it is convenient if the Pivot axis essentially level with the surface of the Mounting plate is arranged.

To pivot the swivel lever in the open position to limit, it is beneficial if the pivot lever in the Open position with one adjacent to the swivel axis free end opposite stop edge on the mounting plate rests.

A particularly simple and inexpensive attachment of the Shoe on the rolling / sliding unit results when as a fastening device to attach the walking shoe on the Roll / slide unit in the midfoot or heel section a spring clip is provided with side bolts towards the shoe, which creates a three-point fixation of the shoe on the mounting plate of the rolling / sliding unit, which results in a good driving feel required stability of the connection between Roll / slide unit and shoe guaranteed.

Advantageous configurations of the foot pedal result from claims 16 to 26, where the same is already in the The advantages described in connection with the rolling / sliding unit also result in the pedal pedal according to the invention. At a Pedal pedal it is also not necessary to have a fastening device to be provided in the midfoot or heel area, through which a movement of the shoe to be fastened in its Longitudinal direction is avoided because due to the crank movement Pedal pedals such a movement in the longitudinal direction more unintentionally Way does not occur anyway.

The inventive shoe of the type mentioned is characterized in that in the forefoot section in the bottom of the sole of the shoe a recess for receiving the Swivel lever is provided, wherein for locking with the A pivot pin in the recess is essentially vertical is provided to the longitudinal axis of the shoe. With the help of arranged perpendicular to the longitudinal direction of the shoe Bolt together with the recess in which the bolt is arranged is, results when inserting the pivot lever into the Recess a positive guidance, which leads to a stable, form-fitting Connection between shoe and rolling / sliding unit or Pedal pedal leads if the shoe is lifted off the mounting plate not possible. This can be the case with the invention Rolling / sliding unit through a in the midfoot or Fastening device provided in the heel area reliably be prevented.

When connecting the shoe with the invention Pedal pedal, is - comparable to a conventional bicycle clip - Although loosening the connection without opening additional Fastening devices possible, but results during a crank movement is a load play, in which reliable ensures the desired connection between shoe and foot pedal is.

In order to provide the guiding lever with a guide surface, which the swivel lever reliably grips the bolt, it is favorable if the recess in the longitudinal section in Is essentially segment of a circle.

For an easy and reliable fixation of the shoe on it is a roll / glide unit in the midfoot or heel area favorable if the shoe locks in the midfoot or heel area has a recess on both outsides. In the lateral recesses of the shoe sole can thus be resilient mounted, laterally arranged bolts for a positive fit Project connection into the recesses.

For a structurally simple design of the shoe it is advantageous if the sole of the shoe is one-piece Bolt-bearing insert with side recesses has, which preferably from one over the rest Sole material is made of hard material because it is high Stability of the attachment of the shoe on the rolling / sliding unit or the foot pedal is given, while the remaining sole material can be designed softer, whereby the walking comfort of the Shoe is not affected.
