  • the present invention relates to a sports shoe according to the preamble of claim 1.
  • the present invention relates to a sports shoe with a foldable undercarriage, the shoe comprising a sole which has a base and a cavity for receiving the foldable undercarriage, which is equipped with a plurality of rollers.
  • This sports shoe can therefore be used as a normal shoe as well as a roller skate, i.e. can enter rooms and climb stairs or use suitable surfaces.
  • Known sports shoes with this dual function have various shortcomings that lead to an increased risk of accidents.
  • Such a sports shoe is described, for example, in German utility model DE-U-29717652.
  • This shoe comprises a two-part stiff sole, the lower part of which has a bore on both the heel and toe side, which serves as a pivot bearing and in which a rail equipped with rollers is pivotably mounted.
  • the bottom part of this sole is made of a softer material, which should make walking easier.
  • CONFIRMATION COPY insufficient The distance between the sole of the shoe and the floor turns out to be insufficient when rolling in a curve.
  • the axes of rotation of the rollers in the active position are still within the sole. Since the rollers have relatively small diameters, this construction cannot create a safe ground clearance.
  • the rollers wear out very quickly due to their small diameter.
  • the aim of the present invention is therefore to provide a sports shoe of the type mentioned, which is equipped with foldable wheels as described above and which on the one hand allows walking comfortably and on the other hand ensures increased safety when rolling.
  • the undercarriage comprises a carrier and a rail articulated thereon.
  • the carrier in particular a frame, is connected to the sole within the cavity.
  • the rail to which the rollers are attached is articulated on the carrier in such a way that the axes of rotation of the rollers lie outside the base of the sole when they are unfolded.
  • a locking device is provided with which this rail, respectively. the rollers attached to it, in the folded or unfolded state, are firmly positioned.
  • the distance between the floor and the base of the sole plays an important role for safety when cornering. This distance can be increased significantly by attaching the swivel joint that connects the rail to the support frame in such a way that the swivel axis is offset as close as possible to the standing surface and laterally outside the space occupied by the castors when they are unfolded.
  • rollers This arrangement also allows the rollers to be replaced easily since they are attached in such a way that their axes of rotation, when folded out, lie outside the base.
  • the undercarriage is locked with the help of a pin that is in a guide is mounted in the sole and is inserted into a hole in the chassis.
  • this solution does not lead to a firm anchoring between the undercarriage and the sole, ie it allows the undercarriage to float relative to the sole, which does not allow stable and safe rolling and thus also impairs comfort and safety.
  • the device for locking the undercarriage according to the invention is mounted on the fixed frame. This lock immobilizes the rail with the rollers in both the folded and unfolded positions.
  • the swivel joint and the locking device are each offset from the plane of movement defined by the rollers and lie outside the space occupied by the rollers.
  • the locking system is actuated by means of a button which is located at the rear of the heel of the shoe.
  • the chassis can be unlocked at an unsuitable moment by an unfortunate impact and, for example, move into its active position or it can fold in while the vehicle is rolling. This increases the risk of accidents.

Abstract

L'invention concerne une chaussure de sport présentant un train de roulement rabattable, monté sur la chaussure (10). Cette dernière (10) est pourvue d'une semelle évidée (20), dans la cavité (28) de laquelle est fixé le train de roulement, et dont la partie marginale forme une surface d'appui (29). Le train de roulement comprend un support (12) et un rail (14) qui est monté de manière pivotante sur le support (12) et qui présente des roulettes (50). Ces roulettes sont alignées les unes derrières les autres et peuvent tourner librement autour de leur axe de rotation respectif (53). Ces roulettes définissent un plan de déplacement (55) perpendiculaire aux axes de rotation (53). Une articulation pivotante (35) est placée entre le support (12) et le rail (14), à l'extérieur du plan de déplacement (55), de sorte que le rail (14) peut pivoter d'une première position rabattue, dans laquelle les roulettes sont entièrement encastré dans la cavité (28), vers une deuxième position dépliée, dans laquelle les axes de rotation (53) des roulettes (50) sont placés à l'extérieur de la surface d'appui (29).
