Definitions

  • the invention relates to an inline skater with a plurality of rotatably mounted rollers aligned in the running direction and a brake assigned to the penultimate and / or last roller.
  • WO 98/45003 discloses a brake for inline skaters, in which braking is also carried out over the running surface of a roller. Since the tread is always dirty, the braking effect is greatly reduced on the one hand and on the other hand unwanted braking can occur when applying dirt, which can lead to a serious fall.
  • EP 0 962 238 A2 discloses an inline skater with an inline shoe, the shaft of which is arranged on a foot part so as to be pivotable.
  • Four rollers are rotatably mounted on a sole of the foot part between two parallel roller flanks.
  • the inline skater has a brake with a brake pad, the brake being pivotably mounted on the roller flanks and secondly being connected to the shaft of the inline shoe via a linkage. is bound.
  • driving the shaft is in a slightly forward-facing position, with the brake pad above the ground.
  • the shaft is brought into an almost vertical position by stretching the leg, which causes the brake pad to come to rest on the ground due to the forced control by the linkage.
  • the brake pad is subject to a relatively high level of wear, since it comes into direct contact with the ground when braking, which generally has a relatively rough, uneven surface, and thus achieves a braking effect caused by friction.
  • the unevenness of the floor creates different frictional forces, which makes braking difficult.
  • the invention has for its object to provide an inline skater of the type mentioned, the brake works reliably with a given long life.
  • the brake acts on a roller axle carrying the corresponding roller and can be acted upon by a load perpendicular to the roller axis.
  • the brake comprises a brake pad acting on the roller axle when loaded, the roller axle being assigned a free movement space pointing in the direction of the brake pad.
  • the roller does not brake at the slightest load when driving.
  • the brake is only applied after a certain stroke has been overcome, the roller being held in its lower position either by gravity or by a spring (not shown) when not loaded.
  • the roller axle carries a coaxial brake pad which is firmly connected to it, the brake pad having a brake surface which is adapted to the circumference of the brake pad and is held on the inline shoe and / or on the roller flanks which support the roller .
  • a new brake pad can be glued onto the roller axle.
  • the desired braking effect can be achieved by selecting different materials for the brake pad.
  • the brake pad is preferably pressed in the direction of the brake lining of the roller axis when a load is applied via at least one spring element.
  • the brake pad is therefore already on the braking surface before full braking power is reached and when the brakes are already light, the brake is self-cleaning.
  • the path of the brake pad is expediently limited by a stop attached to the inline shoe and / or to the roller flanks. If the brake pad is worn too much, a rattling of the brake pad indicates that the brake pad needs to be replaced.
  • the brake pad must always be held in its optimal position. This is achieved in that the brake pad is held away from the braking surface of the brake pad by a return spring. Due to the spacing between the brake pad and the braking surface, it is not possible to grind these parts against one another when the vehicle is driving without braking.
  • the brake pad can be adjusted in the direction of the braking surface via an infeed mechanism provided on the inline shoe and / or the roller flanks.
  • an infeed mechanism provided on the inline shoe and / or the roller flanks.
  • a brake rocker is mounted on a pivot point provided on the inline shoe or on the roller flanks, the brake rocker having a brake pad assigned to the roller axis or its braking surface and adjusting means influencing the path of the brake rocker.
  • the position of the Brake rocker affects the braking surface, which ensures a uniform braking behavior.
  • the actuating means are a stop limiting the path of the brake rocker to the roller axis and a spring acting on the brake rocker in the direction of the roller axis.
  • the brake rocker is a one-sided lever, at one end of which the pivot point is present and at the other end of which the brake pad is attached, the stop and the spring acting on the brake rocker at the end opposite the pivot point.
  • the brake rocker is advantageously assigned to two adjacent roller axes, the pivot point being in the region between the roller axes.
  • the last roller should have a higher braking effect than the penultimate roller, so that the inline skater always lies on the ground with the braking rollers and the tipping point roller.
  • the pivot point of the brake rocker is therefore expediently adjustable via an actuating gear mounted on the inline shoe or the roller flanks, with adjusting means securing the position of the brake rocker relative to the roller axles.
  • the actuating gear preferably comprises at least one rotatable actuating rod which is fixed in its position and which projects through a pivot bolt which has the same thread in a central threaded region, the pivot bolt in a setting which runs in the direction of the actuating rod and is incorporated in the brake rocker - Elongated hole slides.
  • a fixed brake pad is expediently assigned to a roller axle and an adjustable brake pad is assigned to a further roller axle.
  • the braking force can be adjusted for the roller with the adjustable brake block.
  • the fixed brake pad is therefore assigned to the last roller and the brake pad adjustable via a feed mechanism to the penultimate roller.
  • the feed mechanism adjusts the contact pressure of the spring-loaded brake pad by means of a wedge that can be adjusted by means of a threaded pin.
  • the rollers used for braking have a free range of motion.
  • the feed mechanism expediently adjusts the free movement space of the roller axis by means of a wedge that can be moved by a threaded pin.
  • At least the last roller is held in a brake arm rotatably mounted on the inline shoe or the roller flanks, and a brake block fixed on the inline shoe or the roller flanks acts on the roller axis during pivoting, the pivot point the brake arm is in front of the roller axis in the direction of travel. Moving the pivot point in front of the roller axle to be braked results in a safe driving experience.
  • a free movement space is assigned to the last roller according to a further embodiment, and a rotatably held brake bar acts on at least one further roller axis, the pivot point of the brake bar lying between the last roller and the penultimate roller. This means that the last roll can be braked slightly before the last roll is braked, before the last roll brakes strongly after overcoming the entire clearance.
  • the brake strip preferably has spring bars in the area between the rollers to be braked.
  • a different braking behavior can be achieved by changing the spring bars or arranging the spring bars at different distances from the rollers.
  • the roller axle is rotatably supported in roller flanks, and a brake package brings about a braking effect on the roller axle when the corresponding roller is loaded.
  • the roller axis of the roller to be braked is lifted out of the height of the other rollers, so that the roller can only come into contact with the ground by tilting the inline skater backwards.
  • the brake package is expediently a prestressed disk spring package which is acted upon by a collar on the roller axis and which is supported on the roller flanks. The force is thus applied directly to the roller axis.
  • the brake package consists of two diametrically opposed roller-fixed roller disks on the one hand and two roller flank-fixed side disks lying against the roller disks, the roller disks and the side disks having braking surfaces that run obliquely to the roller axis.
  • the brake package comprises a pressure pad assigned to the skater's heel in the inline shoe, which is connected to a brake cylinder, the self-resetting cylinder rod of which acts on the roller axle or its braking surface via a brake block attached to the cylinder rod.
  • a conical bore for receiving a corresponding conical brake pad is in each case embedded in the end of the roller axis, the brake lining being arranged on the circumferential surface of the bore or the brake pad. Due to this measure, the roller axis is not additionally subjected to bending during the braking process.
  • the conical design of the bore and the brake pad enables stepless braking depending on the load, whereby a relatively large area is made available for the brake pad.
  • the end of the roller axle carries a brake lining which widens conically to the roller and overlaps a corresponding inner cone of a brake pad.
  • the roller flanks in the area of the last roller are replaced by a U-shaped bracket divided into two in the web, the legs of which are fixed at least on the roller flanks of the penultimate roller and the web is held together by a screw connection.
  • the legs of the bracket are expediently fixed by means of axle screws inserted in the end of the roller axles of the penultimate and third-last rollers.
  • axle screws inserted in the end of the roller axles of the penultimate and third-last rollers.
  • existing fasteners in the area of the rollers are used to fix the bracket.
  • the relatively simple interchangeability of wear parts of the brake is possible because after the bracket has been removed, the brake blocks are removable and can be replaced if necessary.
  • each brake pad is advantageously arranged in a rotationally fixed manner on the associated leg of the bracket and positively controlled via a slope on its free end face, which interacts with a bevel of the leg. This eliminates the need for an additional mechanism to act on the brake pad.
  • the brake pad preferably has a spring on its free end face which engages in a corresponding groove in the wedge face.
  • the spring can be integrally formed on the brake pad or inserted into a groove in its free end face and, in cooperation with the corresponding groove of the wedge surface, ensures the non-rotatable and displaceable arrangement of the brake pad.
  • the free end faces of the brake pads must not be in contact with the adjacent wedge surface. Therefore, the space between the opposite wedge surfaces expediently expands in the direction of the brake pads.
  • the roller axle or the brake pad is preferably acted upon by at least one hold-down device acting downwards.
  • the hold-down device preferably comprises a sliding part resting on the roller axle or the brake pad, which takes up one end of a compression spring, the other end of the compression spring being inserted into an associated leg.
  • the hold-down device ensures the free mobility of the orderly role in the absence of or only little load safely, the sliding part causes little friction on the roller axis.
  • the load for generating the braking action against the spring force of the compression spring is to be applied, as a result of which a detectable braking sensation is generated.
  • the object is achieved according to the invention in that the brake acts on a roller axle carrying the last roller and can be acted upon by a pivoting movement directed rearward about the penultimate roller axle.
  • the brake that acts on the roller axle is subject to relatively little wear and therefore has a long service life. Achieving a reliable and uniform braking effect is ensured by the fact that the surface properties of the roller axis and the brake change only slightly. Furthermore, the selection of suitable friction pairings enables sensitive braking.
  • the brake together with the last rollers is advantageously assigned to a brake module attached to the inline shoe or the roller flanks.
  • the brake module preferably includes a heel angle which receives the heel of the inline shoe and on which a rearward-directed, obliquely downward-running roller holder for mounting the roller with play and for holding at least one brake pad is arranged.
  • the heel angle ensures that the brake module is securely attached to the inline shoe and a correspondingly large-scale distribution of the forces introduced into the brake module via the roller during braking.
  • the roller axis expediently shifts when the last roller is loaded in the direction of the brake linings arranged on both sides of the roller, the brake linings coming into contact with the braking surfaces assigned to the roller axis.
  • the object is alternatively achieved according to the invention in that the brake is fastened to a pivotable shaft of the inline shoe and, when the shaft is pivoted backward, acts at least on a roller axle carrying the last roller via a brake linkage.
  • the brake comprises a roller holder which supports an additional roller and which is articulated on the shaft and the brake linkage in such a way that the additional roller comes to rest on the floor when the shaft is pivoted rearward.
  • the zu- Set roller thus ensures a relatively high level of stability during braking and is a low-wear component of the brake for actuating the same.
  • the brake linkage advantageously comprises an actuating rod fastened to the shaft and to the roller holder and at least one brake rod holding at least one brake pad acting on the roller axis and connected to the roller holder via an intermediate rod.
  • the angle through which the shaft has to travel until the braking effect is established is determined by appropriate dimensioning of the lever length ratios of the brake linkage.
  • a particularly safe and maintenance-friendly brake is made available in that the brake rod preferably has elongated holes for receiving all existing roller axles, a brake pad being inserted in each of the elongated holes. Due to the simultaneous application of all roller axles by means of the brake pads, a relatively large friction surface is available, which enables quick braking.
  • the brake pads which are made of an elastomer, for example, are fastened with a light press fit in the elongated holes of the brake rod and can be easily replaced if necessary.
  • the brake rod is expediently inserted between the roller flanks holding the roller axles and the rollers.
  • the guide of the brake rod results in the longitudinal direction through the elongated holes receiving the roller axles and brake linings and perpendicular to it through the assigned roller flank and the rollers.
  • a brake rod is preferably arranged on each side of the rollers. In this way, a maximum braking effect can be achieved using all free surfaces of the roller axles.
  • the brake rods in front of the front roller are connected to each other by a web that carries an elastomer buffer. At the same time, the web causes the brake rods to move simultaneously when the roller holder acts on them.
  • the roller holder is pivotally attached to the inline shoe via an obliquely extending elongated hole which receives a guide pin for the roller holder fastened between the roller flanks and is in each case connected to both the actuating rod and the brake rods by means of a pin connection Connection.
  • the roller holder When the shaft is pivoted backwards, the roller holder expediently executes a pivoting movement which pulls the brake rods backwards, the brake linings arranged in front of the roller axles coming into contact with the roller axles.
  • the roller holder is connected to the actuating rod and pivotably connected to the brake rods via the intermediate rod.
  • the pivoting movement of the shaft is also deflected into a linear movement the brake rods realized with simple mechanical means.
