Definitions

  • the invention relates to a roller skate.
  • the invention relates in particular to a roller skate which has a front wheel in front of a step surface and a rear wheel behind a step surface, as well as a braking system, in the direction of movement.
  • a roller skate is known, e.g. B. from the EP 0 486 013 A1 .
  • the roller skate is used z. B. for summer training for biathletes or Nordic skating, where sticks are used in addition to roller skates.
  • the WO 2015/110167 A1 , the DE 199 16 588 A1 , the DE 202 06 709 U1 and the US 2009/134589 A1 show roller skates or roller skis with braking systems.
  • roller skates are not suitable for all terrain, they only work on level ground. This is also due to the lack of rigidity of the known constructions. If there are brakes in known roller skates, they only function to a very limited extent in the field. There is therefore the task of proposing a roller skate that can also be used reliably on uneven terrain. The object is achieved with a roller skate according to claim 1.
  • the roller skate according to the invention has a step surface, a front wheel which is arranged in the direction of movement in front of the step surface, and a rear wheel which is arranged in the direction of movement behind the step surface, and is characterized in that the step surface is the top of a box frame.
  • the roller skate has a brake system, the brake system according to an embodiment according to the invention having at least one, advantageously two hydraulic disc brakes per roller skate, the brake cylinder of which is received in the interior of the box frame, the brake cylinder engaging a brake lever attached to the side of the box frame stands, and wherein the brake lever is adjustable parallel and transverse to the direction of movement of the roller skate.
  • the box frame preferably has a top and a bottom side as well as side walls.
  • the height of the side walls determines the height of the box frame.
  • the top serves as a one-piece, rigid tread on which the driver's foot rests.
  • the width of the step surface is preferably as wide as a foot. It is further preferred if the step surface or the box frame is no longer than a foot's length. In this way it is possible to build a compact roller skate that can be controlled by simple movements of the rider, e.g. B. a curve is initiated by turning the foot.
  • forks are formed that hold the axles of the front and rear wheels.
  • the step surface is advantageously arranged below the hub of the wheels.
  • the top and bottom and the side walls are designed as closed surfaces. But it is also possible to make the top and bottom and the side walls partially permeable, for. B. made of expanded metal or a sheet metal which is provided with recesses.
  • the box frame is preferably made of metal, e.g. B. made of stainless steel or aluminum.
  • the side walls are preferably 1 cm to 5 cm high, so that the top and bottom are arranged at a distance of 1 cm to 5 cm.
  • the top and bottom are advantageously arranged parallel to one another.
  • the box frame can also have a front and / or rear wall, so that the box frame is designed as a largely or completely closed housing.
  • a closed housing of the box frame contributes to the stability of the roller skate, especially when the roller skate is used on uneven terrain.
  • a side or wall of the box frame can be opened if necessary in order to make the interior of the box frame accessible.
  • the brake system provides that at least one hydraulic disc brake is provided per roller skate (front wheel and rear wheel), which is preferably arranged on the rear wheel.
  • Two disc brakes are advantageously provided, one of which is arranged on the rear wheel and one on the front wheel and which are each arranged on one side of a wheel.
  • the disc brake or the brake calipers of the disc brake are connected to a brake cylinder via a hydraulic line.
  • the brake cylinder is arranged in the interior of the box frame. This arrangement is particularly advantageous because the sensitive brake cylinder in the interior of the box frame is very well protected from damage and contamination.
  • the or, in the case of two disc brakes, optionally also the brake cylinder is or are operated by means of a brake lever which is attached to the side of the box frame.
  • the brake lever extends upward from a first end on a side wall of the box frame to a second end.
  • the brake lever advantageously extends to the calf below the knee.
  • the brake lever is pivotable; it is advantageously mounted on the box frame via a shaft that penetrates the side walls of the box frame. According to a further preferred embodiment, the shaft is mounted in a bush.
  • the brake lever actuates the brake cylinder or cylinders by pushing the brake lever backwards or downwards by the driver.
  • the brake lever stabilizes the driver vertically in relation to the roller skate because not only is the shoe secured to the roller skate, as will be explained in more detail below, but also because the calf lever provides a second fastening point at a distance from the roller skate.
  • a particularly simple and effective embodiment of the brake system provides that a means for actuating the brake is provided between the brake lever and the brake cylinder.
  • the means for operating the brake can be arranged as a pivotable angle on the box frame, the z. B. is pivotable about an axis which runs parallel to the direction of travel.
  • One arm of the bracket extends horizontally over the side wall of the box frame to under the brake lever. During the braking process, this horizontal arm of the angle is pressed downwards.
  • This process is simplified in particular if a pusher is attached to the brake lever that presses on the horizontal arm of the bracket. According to a further preferred embodiment, this pusher can be adjusted so that the braking point can be adjusted exactly.
  • a vertical arm of the bracket extends within the box frame, which does not have a completely closed cross-section, at least at the point where the bracket is attached.
  • the vertical arm of the bracket is moved sideways into and up the box frame during braking.
  • the vertical arm of the bracket actuates the brake cylinder, usually the piston of the brake cylinder.
  • Pressure is built up in the hydraulic brake so that the brake calliper rests against the brake disc and the wheel is braked.
  • the pressure in the hydraulic brake can, for. B. 150 bar and more. If several brake cylinders are to be actuated, the vertical arm of the bracket is designed to be correspondingly long or it has several sections which each come into engagement with one or two brake cylinders.
  • the means for actuating the brake can also be designed as a displaceable pin pretensioned by a spring, which outside of the box frame has an upper side beveled towards its underside.
  • the brake lever When the brake lever is actuated, the pusher in engagement with the bevelled upper side of the pin generates a movement of the pin in the direction of the brake cylinder and pressure is built up in the brake, which leads to a braking of the wheel.
  • a completely closed box frame can be used with this design.
  • safe braking is also easily possible from speeds of 30 km / h to 40 km / h.
  • the brake lever is actuated by the driver's calf and must be optimally adjusted to the driver for this purpose, in terms of height, length and centered on the driver's calf in relation to the box frame.
  • the brake lever advantageously has a joint, whereby the brake lever is divided into a lower and an upper lever. Through the joint, the inclination of the upper and lower brake levers can be individually adjusted to the user, so that the brake lever can be aligned parallel to the direction of movement closer to the front wheel or to the rear wheel.
  • the upper and lower levers are fixed in their inclination to one another, e.g. B. by a screw that fixes the two levers or by a quick release lever.
  • the first end of the brake lever is connected to the shorter lower lever and the second, upper lever extends from the joint to the second end of the brake lever.
  • the brake lever preferably has a length and thus a height adjustment, in particular a telescopic rod which, with respect to the brake lever, is displaceable and is arranged with means for locking the telescopic rod on the brake lever.
  • the telescopic rod is z. B. fixed by a clamp, a screw or a quick release lever on the brake lever.
  • an extension arm is advantageously attached, which preferably extends up to at least half the width, in particular over the full width of the step surface.
  • a support for the calf is attached, which is adjustable according to an advantageous embodiment, for. B. by a locking device such as a quick release lever attached to the boom.
  • the support for the calf is adjustable both in terms of the distance from the brake lever, that is, transversely to the direction of movement or to the step surface, and in terms of inclination and can therefore be individually adapted to the driver. It has been found that the fastest and most immediate braking reaction results from an unconstrained automatic movement of the driver who operates the brake lever with his calf.
  • a front wheel and a rear wheel with a diameter of at least 300 mm are used, advantageously up to 400 mm, in particular from 300 mm to 350 mm, in order to be able to ride the roller skate as safely and quickly as possible even on uneven terrain.
  • the size of the wheels in conjunction with the brake system according to the invention ensures safe driving both on flat stretches and on uneven terrain. This is the roller skate, so the single-track device for rolling locomotion, separated from other z.
  • roller skates or skaters that have three or four wheels under the tread. Air-filled tires are preferred.
  • the wheels are attached to the forks via axles, which are arranged on the box frame. The wheels are designed to run straight ahead, steering by changing the direction of travel of one wheel relative to the other wheel is not provided.
  • a backstop can be attached to one or both wheel axles his.
  • a backstop is z. B. known for bicycles with coaster brakes and can be easily installed in the wheels or hubs of the roller skate according to the invention. This further improves the cross-country mobility of the roller skate according to the invention, because larger gradients can be better managed even in narrow terrain.
  • the roller skate can either have a shoe firmly connected to the roller skate or a binding for any type of shoe.
  • the roller skate has a binding, in particular a standard binding such as. B. an SNS binding, optionally supplemented by a further fastening of the shoe in the area of the instep by means of a toothed belt for additional securing of the shoe.
  • the further fastening can be designed as a toothed belt, as a Velcro fastener, as a fixed, elastic belt or as a clasp. This additional fastening ensures that the shoe is guided precisely when the shoe moves up and down in relation to the tread surface.
  • roller skate Due to the construction of the roller skate with a brake arranged in the box frame and with a lateral calf lever, it is possible to use the roller skate according to the invention, especially if an additional fastening of the shoe is provided, with a parallel cross-country step in which the driver's heel regularly moves stands out from the tread. No known roller skate offers this possibility.
  • the roller skate 1 a single-track device for rolling locomotion, knows how in Fig. 1 can be seen, a step surface 2, a front wheel 3, a rear wheel 4 and a brake system 5.
  • the front wheel 3 is attached in the direction of movement indicated by the arrow "B" in front of the step surface, the rear wheel 4 is attached behind the step surface 2.
  • the wheels 3, 4 are attached to forks 6 which extend upwards from the tread 2, because the tread 2 is lower than the axes 7 of the wheels 3, 4.
  • the tread 2 has a width and a length that corresponds to the width and length of a shoe.
  • the roller skate 1 is made of aluminum, alternatively of stainless steel.
