DESCRIPTION:
BRIEF SUMMARY
The invention relates to an inline roller skate according to the preamble of claim 1 and also to an interface for the roller unit of such an inline roller skate. The term inline roller skate is understood to mean a one-track roller boot in the widest sense.
In recent years the number of inline roller skates has shown a clear increase. Precisely in the city area, with the traffic density prevailing there, relatively short distances can be covered significantly more quickly with these means of locomotion than with other means of transport. However, for longer distances public means of transport or vehicles are faster and more comfortable. As a result of the prevailing prohibitions of inline roller skates in, for example, underground railway areas the inline roller skater must also carry normal shoes and put these on if required instead of the inline roller skates. For improvement boots have been developed with removable rollers and roller units which can be mounted on normal shoes. However, known systems with removable rollers are usually laborious to assemble and/or provide inadequate steadiness and therefore lack optimum travelling properties.
From U.S. Pat. No. 507 506A (SHADROUI), for example, a roller boot of the kind specified is known which for the purpose of easy and rapid interchangeability of the roller unit on the boot sole is equipped with an interface constructed after the fashion of a channel into which a correspondingly shaped roller support can be inserted. The connection between the roller unit and the boot is locked by a resiliently mounted lever in the heel area. Unlocking is performed by forcing the lever downwards while at the same time displacing the boot in relation to the roller unit. The constructional elements, necessary for the connection to the roller unit, in the form of a channel-like structure on the boot sole can easily become dirty or damaged, so that the boot is not suitable for walking without the roller unit. Moreover, the structures on the boot sole, which must be made from particularly resistant material to achieve adequate resistance, adversely effect walking comfort. The weight of the boot is also increased thereby. Furthermore, stepping in and out is laborious, since the correct positioning of the structure of the roller unit in the channels on the boot sole calls for a certain skill and the boot must be moved in the longitudinal direction of the roller unit and therefore the roller unit would roll away during stepping in and out, so that it must be retained tightly. During stepping out the lever, which is placed very low, must be actuated and the roller unit held at the same time.
An object of the invention is the provision of measures whereby an inline roller skate is created which not only rolling the most optimum travelling properties possible, but also comfortable walking after removal of the roller unit is made possible. Another object is to enable the attachment or "buckling-on" of the roller unit to the boot to be performed as quickly and simply as possible accompanied by the necessary security of the connection. The disadvantages of known systems are to be obviated or at least reduced.
The problem according to the invention is solved by the features that the interface extends upwards from the boot sole laterally along the boot body and preferably consists of a harder material than the boot body, and the roller unit is provided with standing plate substantially horizontal in the position of use and side walls substantially vertical in the position of use for the reception of the interface, so that in the position of use a substantially perpendicular possibility of stepping with the boot into and out of the roller unit is created, and the device for locking and unlocking the roller unit to and from the interface engages in the interface outside the area of the boot sole. According to the invention a commercially available sports shoe with the interface of preferably harder material than the shoe body can be adapted for inline skating. (Translator's note: In thi
