Definitions

  • the invention relates to a transportable (portable and / or rollable) device for processing a surface, in particular the running surface, a runner, in particular a skate runner, according to the preamble of claim 1, according to the preamble of claim 6, according to the preamble of claim 9 , according to the preamble of claim 10 and according to the preamble of claim 11.
  • the device comprises an electric drive, which is arranged in a housing, in particular as a portable and / or rollable case, for rotating a polishing pad rotatably mounted in the housing formed surface treatment agent.
  • the device further comprises a control device, which is arranged in the housing and has actuating means, for controlling / regulating the drive of the surface treatment agent.
  • the invention also relates to a method according to claim 15, ie a method for processing a surface of a blade, in particular an ice skate blade, in particular with a device described herein. Finally, the invention relates to a skate blade according to the preamble of claim 22.
  • the invention is based on the object of specifying measures with which the maintenance of ice skates, in particular ice skate blades, is simplified, improved, in particular with regard to the sliding property of the blade, and thereby becomes more reproducible.
  • This object is achieved by a transportable device for processing a surface of a runner, in particular a skate runner, according to claim 1.
  • the surface to be processed essentially relates to the running surface of the runner, ie that narrow side of the runner which faces the ice surface on which it is intended to slide.
  • the surface processing agent accordingly has a processing zone in the area of the circumference which has a cross-sectional area with a slope and / or a taper and / or a chamfer and / or a rounding.
  • the device is able to polish the (already ground) runner, in particular to polish it to a high gloss, as a result of which the surface (running surface) of the runner receives an, in particular high-gloss, machining finish.
  • a high-gloss polished running surface of the runner has a reflective sheen and a correspondingly smooth (running) surface.
  • the runner with finish machining has better running and sliding properties and, thanks to the features of the device described herein, these improved surface properties of the runner compared to the prior art can also be reproduced at any time at the place of use of the runner.
  • the surface processing agent can preferably comprise a textile fiber material such as felt, in particular wax and / or a diamond additive, for example diamond dust, or be formed from textile fiber material such as felt, in particular wax containing.
  • a textile fiber material such as felt, in particular wax and / or a diamond additive, for example diamond dust
  • be formed from textile fiber material such as felt, in particular wax containing Excellent sliding properties are achieved when the processing zone of the surface treatment agent is slightly narrower than the blade width (sliding on the ice surface), so that the edges of the blade (sliding on the ice surface) remain unprocessed when the surface of the blade is processed.
  • the rotating surface treatment agent is arranged under a shield and / or in a cage, so that only a segment of the surface treatment agent is accessible during machining.
  • the rotating surface processing agent can be safely operated at high speed and high torque. Since only one area of the rotating surface treatment means is accessible during the surface treatment, deviations in operation are avoided and the surface treatment always takes place in the same way, that is to say with an almost identical position of the runner relative to the surface treatment means. It can be provided that the surface treatment agent is changed, in particular when it is worn.
  • the processing zone of the surface processing agent is that area with which the runner is processed, i. H. the outer area of the polishing or grinding wheel. It can be the case that the processing zone is composed of a different material than the rest of the disk, for example a harder material or a softer material. Due to the shape of the cross section of the processing zone with bevels or bevels or with tapering or tapering or with one or two bevels on the edges of the processing zone, a suitable adaptation of the shape of the processing zone to the shape or contour of the surface of the runner, or almost to it, is possible, in particular an (almost) complementary contour (example: curvature in the processing zone geometrically matching the curvature of a hollow section or a hollow shape).
  • An even smooth polish is also possible, the surface of the runner being at least partially flat.
  • a surface image with a curvature is also achieved, either concave (for example in the case of a hollow cut) or convex (for example in the case of a curved cut). It is also possible to achieve a profile with an outwardly tapering runner, in which the contact surface is less than the thickness (width) of the runner.
  • the shield and / or the cage can be at least partially opened for maintenance purposes, in particular for adjusting or replacing the surface treatment agent, in particular by means of a hinged and / or rotatable and / or displaceable maintenance cover.
  • a guide means is provided for guiding the runner during the surface treatment of the runner, the guide means preferably comprising at least one guide plane and / or at least one guide rail.
  • the position and / or inclination of the runner are defined by the guide means and each runner is polished under almost identical geometric conditions. In this way, a reproducible surface processing result is achieved, especially because angle-related deviations from the desired surface appearance remain under. It can be useful if the guide means comprises a holder for the runner and / or the ice skate.
  • the spatial position of the guide plane and / or the guide rail and / or the holder can be mechanically changeable, in particular adjustable, in at least one direction in space, preferably in three mutually perpendicular directions in space (x, y, z).
  • Either the runner or the skate is fixed in the holder, for example with fixing screws or with a clamping arrangement.
  • the guide means with a fixed runner or with a fixed shoe is then guided along the polishing wheel in a controlled manner, for example on the guide plane which is part of the device.
  • the holder of the runner and / or the guide plane can be movably adjustable in one or more spatial directions, for example with a combination of several (screw-mechanical) inclination adjusters on the holder and / or management level.
  • the transportable device comprises a preferably positionable lighting means, the edge of the runner is always processed under identical lighting conditions.
  • a reproducible surface treatment result can also be achieved in an environment that is not brightly lit. This is of particular relevance, for example, when the runner is used at a sporting event, i. H. in ice hockey or speed skating or figure skating should be worked on during a break or immediately before the event, which is usually done in less well-lit lounge or changing rooms.
  • At least one grinding means and / or grinding module is provided for rough machining of the skate blade, so that grinding can be carried out before the surface polishing or finishing machining.
  • the runner is thus first ground with the device (rough treatment of the runner surface) and then (high-gloss) polished (finish machining of the surface).
  • an excellent surface treatment result is achieved for a heavily worn or heavily stressed runner.
  • an optional grinding module can have its own drive and / or its own control and / or its own housing, so that the grinding module and polishing module can be transported separately, for example in a modularly designed, multi-part housing or transport case. This makes the weight of the device easier to handle when it is being transported.
  • Each module can have its own mains connection and can therefore be operated independently of the other module.
  • a common power supply for both modules can also be provided.
  • the modules can be coupled to one another by means of a module connection, wherein the module connection can comprise mechanical and / or electrical connecting elements.
  • a positioning aid in particular optical or laser-optical, is provided for positioning / aligning the runner and / or the ice skate and / or the surface treatment means.
  • the positioning aid can, for example, project a laser-optical marking onto a (if necessary scaled) reference surface in or on the device or in or on the device housing, with the help of which the blade / skate and / or a guide means of the device (blade holder) is positioned at a target position for the surface treatment respectively can be adjusted.
  • the control device comprises a control and / or regulating device for controlling / regulating the speed of the surface treatment agent.
  • the control means / regulating means can also keep the speed constant during machining. If necessary, a desired speed can be set.
  • the control means can furthermore comprise an emergency stop switch, with which the device, in particular the drive, is switched off. With the emergency stop function, the device also fulfills the necessary safety requirements.
  • the drive preferably comprises an alternating current motor, for example an alternating current motor for an alternating voltage of 230 V, in particular with a power of at least 250 watts.
  • the surface treatment agent rotates at a speed of at least 3,000 revolutions / minute (U / M).
  • U / M revolutions / minute
  • a speed range between around 3,200 rpm and 4,400 rpm has proven to be particularly useful with regard to optimal finishing of the runner.
  • the uniformity of the action of the drive can be given in particular by controlling / regulating the peripheral speed. This makes it possible to compensate for geometric changes in the polishing wheel, for example a reduced diameter in the event of material stress caused by the polishing.
  • At least one coolant can be provided, in particular at least one fan, which is arranged on the housing and / or in the housing so that the heat generated during the surface treatment can be dissipated.
  • the heat that is given off by the drive and / or by the controller and / or by the surface treatment means can thus be dissipated, that is to say given off into the surroundings of the housing. A build-up of heat in the housing is thus avoided.
  • a thermal sensor at least one Components of the drive of the device are de-energized so that the relevant safety requirements are met.
  • the housing can be set up in a height-adjustable manner, in particular by means of a height-adjustable table.
  • the height-adjustable table can be part of the housing or can be connected to the housing. It can also be provided that the housing itself is height-adjustable, for example by means of height-adjustable feet or a height-adjustable frame.
  • the device comprises at least one or more rechargeable electric batteries. This is particularly advantageous when the device is to be operated at a location where no electrical power connection is available. This is regularly the case in ice rinks or ice rink facilities, especially in the adjacent lounge areas or waiting areas.
  • the processing can take place by means of a device described herein.
  • a surface processing agent formed as a polishing disk is provided.
  • a polishing disk can be used for this.
  • a processing zone in the area of the circumference of the surface treatment agent is machined and / or shaped in such a way that the surface treatment agent has a circumferential area with a cross section and / or with a bevel and / or with a taper and / or with a bevel.
  • the processing zone of the polishing wheel therefore has a contour which fits or almost fits the dimensions of the runner in a special way, and which allows a desired profile image (similar to a hollow grind, vaulted grind, smooth grind, or similar to a grind) to be created on the runner inclined course) can be generated.
  • the surface processing agent is set in rotation.
  • the runner is guided along the circumferential area of the rotating surface treatment means.
  • the drive axis of the surface treatment agent is preferably stationary, ie the axis rests within the housing of the treatment device so that the skate or the runner is moved, but not the axis or position of the rotating surface treatment agent.
  • the surface (running surface) of the runner is processed in such a way that the runner glides better, ie faster and / or more stable, over the ice surface.
  • the wearer of the skate of a blade that has been processed in this way can drive faster, i.e. he requires less force, and he can turn more stable, that is, the blade does not slide as easily to the side when the edge is loaded across the direction of travel, which stabilizes the skating.
  • the runner can be guided along such that the preferred direction of movement of the runner (corresponding to a forward sliding movement) and the direction of rotation of the circumferential area run in opposite directions or in the same direction.
  • the runner can accordingly be guided along the polishing wheel against the direction of rotation or with the direction of rotation.
  • an opposite direction of movement is provided, with the runner being guided along the polishing wheel against the direction of rotation with regard to the desired high-gloss polishing result. So it can work in opposite directions or processed simultaneously, depending on the desired profile picture or grinding result.
  • a profile image or surface finish can be created in the runner, which, based on the cross-section of the runner, has at least one slope, preferably two opposing slopes, which forms a hollow profile or a hollow shape, and / or which has a contour, preferably one or more curvatures which form a hollow profile (hollow shape), and / or a recess which forms a hollow profile (hollow shape).
  • a polishing agent for example a polishing paste.
  • the paste can contain microparticles and / or nanoparticles, which participate in the polishing process.
  • the runner provision is made for the runner to be shiny, in particular high-gloss, at least in some areas after the surface has been processed.
  • the gloss of the runner goes hand in hand with a particularly advantageous sliding and running properties of the corresponding ice skate.
  • the shiny area of the runner is visually perceived by the user, so that he can immediately distinguish a surface-processed runner from an unprocessed one.
  • the (arithmetic) mean roughness value R a of the machined runner surface is at least in some areas less than approx. 0.1 ⁇ m, in particular less than approx. 0.035 ⁇ m, preferably less than 0.025 ⁇ m.
  • the mean roughness value R a corresponds to an average value of the deviation of the rough surface profile from a reference variable.
  • a value R a test of 0.03 ⁇ m was determined. A runner with a surface of this quality and the resulting improved running properties is unprecedented in the prior art.
  • the method can furthermore be designed in such a way that the (averaged) roughness depth R z of the machined runner surface is less than approximately 0.5 ⁇ m, in particular less than approximately 0.25 ⁇ m.
  • the mean roughness depth R z is an average of several individual roughness depths, with several successive individual measurements being provided depending on the measuring method. In at least one experimental check of the surface quality of a skate blade, the surface of which was polished with the device described herein, an R z test value of 0.2 ⁇ m was determined.
