Definitions

• the invention relates to a roller skate with two pairs of rollers.
• roller skates with two pairs of rollers are known.
• the pairs of rollers are attached to a common plate that can be connected to the shoe.
• the connection to the shoe can be fixed by means of screw connections or detachable by means of belt connections.
• a so-called skateboard is also known in which the pairs of rollers can be pivoted to a limited extent on the rigid mounting plate for better maneuverability.
• the base plate is in no way connected to the shoe. It is an object of the invention to provide a roller skate with two pairs of rollers, in which the normal mobility of the foot in the shoe is not impaired and which nevertheless brings with it an excellent adaptability of the pairs of rollers when cornering.
• a shoe on the .Sohl ensei te with exposure of the shoe middle part in the heel and in the toe area has two slightly inclined mounting surfaces towards the shoe ends, that on these mounting surfaces two identical pedestals, each with two rollers by 180 ° are fixed rotated and that the bearing blocks on the facing sides can be rotated by means of elastic buffers and can be pivotally supported on the shoe on the facing sides by means of rigid guide elements in circular guide receptacles.
• the foot remains movable in the shoe, since the middle part of the shoe is exposed and is not included in the fastening surface of the pairs of rollers.
• the identical pedestals with the pairs of rollers simplify the position of the roller skate. If the roller skate is inclined sideways, the inclined mounting surfaces adjust the bearing axles of the roller pairs. When cornering, both pairs of rollers can pivot independently of one another according to the curve radius. This improves the overall running properties of the roller skate.
• the shoe and the pairs of rollers nevertheless form a unit, which, however, is considerably more adaptable to the requirements than is the case with known roller skates.
• the curve ability of the roller skate according to the invention can be further improved by the fact that elastic intermediate plates and rigid end plates are fastened to the fastening surfaces and that the elastic buffers are rotatably mounted on these end plates and the rigid guide elements are pivotally supported to a limited extent.
• the pivot bearing of the bearing blocks and the limited pivotability of the same are solved in that the bearing blocks have a through hole for a fastening screw, that the fastening screws are guided through a hole in the elastic buffer and screwed into screw receptacles in the end plates, and that the rigid guide elements are in corresponding circular-arc-shaped depressions the end plates are guided to a limited extent.
• the hold of the foot in the shoe is improved in one embodiment in that the shoe is provided with a shaft, a closure flap and a quick release fastener.
• the protection of the foot is achieved in that the upper part of the shoe is formed from rows of transverse beads which are closed at the end with a cleat and that approximately vertically extending cushion increases are attached to the shoe on the outside of the upper.
• a support with a preferably interchangeable brake block can be fixed or fixed on the butt plate or the end plate fixed in the toe area of the shoe. This makes it easier to replace the brake block, which is a wearing part.
• the manufacture of the shoe is simplified and less expensive in that the shoe is formed from the middle part, the shaft, the closure flap and the transverse beads of the upper part as a one-piece plastic part. It can additionally be provided that the inside of the shoe is provided with a cushioning layer in order to obtain comfortable wearing of the shoe.
• the roller skate according to the invention can easily be converted into a skate in that a U-shaped longitudinal carrier with a skid can optionally be fixed to the fastening surfaces of the shoe, the carrier having correspondingly raised fastening blocks at the ends which directly or with the interposition of elastic intermediate plates with the fastening surfaces of the shoe can be connected.
• the runner can be partially embedded in the carrier and rounded at the ends facing the shoe ends.
• the ends of the runners can sometimes be seen with cross corrugations in order to be used as a brake or the like.
• the outer sides of the rollers are closed and approximately dome-shaped, then the ability of the roller skate to corner is improved even further.
• Fig. 3 seen in side view of the inside of a skate converted to ice skate according to the invention
• the shoe 1 and 2 consists of the shoe 10, which is preferably made as a one-piece plastic part 1 and is provided with padding on the inside.
• the shoe middle part 11 merges into the upper part formed from the transverse beads 12 and into the shaft 15, so that the foot finds an excellent grip in the shoe.
• the closure tab 16 with the cutting 1 closure 17 allows the shoe 10 to be opened and closed quickly.
• the tip of the shoe 10 is designed as a cleat 13.
• the cushion increases 32 are attached to protect the foot in the event of a fall.
• fastening surfaces 18 and 19 are formed for the pairs of rollers. These mounting surfaces 18 and 19 are inclined slightly rising towards the shoe ends and contain screw receptacles in a known manner, so that the elastic intermediate plates 21 and 25 and the rigid end plates 20 and 24 can be screwed on.
• the bearing blocks 26 have plate-shaped parts with through holes through which the fastening screws 28 are inserted. These fastening screws 28 are guided through bores of elastic buffers 27 which are supported on the end plates 20 and 24 and are screwed into screw receptacles in the end plates 20 and 24.
• This pivot bearing of the bearing blocks 26 is therefore elastic.
• the pivot bearing of the identical bearing blocks 26 is on the mutually facing sides of the bearing blocks 26, which, however, are rotated by 180 ° and are connected to the fastening surfaces 18 and 19 or the end plates 20 and 24.
• the opposite ends of the bearing blocks 26 are designed as supports 29, which are supported by means of guide elements 30 in circular-arc-shaped recesses of the end plates 20 and 24 limited swivel bar.
• the guide elements 30 can be cone-shaped and end in a dome-like manner. These dome-like ends of the guide elements 30 are supported on flat guide surfaces of the depressions in the end plates 20 and 24 in order to keep the friction losses small when the pairs of rollers are pivoted.
• the rollers 31 are attached to the ends of the axles fixed in the bearing blocks 26, importance being attached to their easy rotatability. There are various known types of fastening. To him is that the rollers 31 are closed on the outside and run out like a dome.
• the bearing blocks 26 can also be connected directly to the fastening surfaces 18 and 19 of the shoe 10 in the same way.
• the elastic intermediate plates 21 and 25, and the end plates 20 and 24 are then superfluous. However, this adversely affects the adjustment when the shoe 10 is inclined to the side.
• the interchangeable brake block 23 is fastened by means of a carrier 22 to the end plate 24 attached in the toe area of the shoe 10. However, it can also be attached to the cleat 13 of the shoe 10.
• FIGS. 1 and 2 show, the roller skate according to FIGS. 1 and 2 can easily be converted into a skate.
• the carrier 22 with the brake block 23 and the bearing blocks 26 with the pairs of rollers are removed from the shoe 10.
• the end plates 20 and 24 are also removed. It is replaced by an integral elongated support 33, which has raised mounting blocks 36 and 38 at its ends.
• These fastening blocks 36 and 38 can be screwed directly by means of fastening screws with the interposition of the elastic intermediate plates 21 and 25 with the screw receptacles embedded in the fastening surfaces 18 and 19 of the shoe 10.
• the central part 37 of the carrier 33 is reduced, so that between the central part 11 of the shoe 10 and the carrier 33 there is a handle opening which makes it easier to carry the skate.
• the carrier 33 partially surrounds the runner 34 over the entire length, so that it protrudes only partially on the carrier 33.
• the ends 38 and 39 of the runner 34 are rounded and partially provided with cross corrugations or the like.
