Description

The invention relates to a system for forming an edge processing device for the manual material-removing machining of ski and / or snowboard edges according to the preamble of claim 1, a method for adjusting the angle between a working section of a processing plate and a support surface of an edge processing device according to claim 12 and the use of a processing plate according to claim 13.

Known manual edge processing devices are usually made of a one-piece file, which is guided by the user along a longitudinal edge while maintaining a grinding angle (angle between the thickness extension direction of the ski / snowboard and the longitudinal edge of the ski / snowboard) to edit the edge material removal. This activity requires intensive practice, as it depends on the processing angle crucial.

In addition to these very simple edge processing devices structurally more complex edge processing devices have become known, these partially consisting of a processing plate holder and a releasably settable processing plate, which projects beyond a support surface of the processing plate holder with a working section, said working section with the support surface spans an angle. In the from the US 4,663,993 A , of the DE 6 919 027 A as well as the DE 1 578 877 A Known edge processing device, this angle is adjustable via screws, which is just difficult for the layman, especially when a defined angle over the entire length extension of the processing plate to be set.

From the US 3,561,169 A For example, an alternative edge processing apparatus comprising a processing plate holder and a processing plate is known, wherein the two components include a fixed angle of 90 °. The known device is characterized by a compact design and in particular by the fact that the processing plate is completely retractable in a receptacle to easily transport the edge processing device can. Since the angle of 90 ° permanently fixed, the known edge processing device is only partially suitable for tuning a ski or snowboard on different snow conditions or desired driving behavior.

From the CH 678 019 a device for editing ski edges according to the preamble of claim 1 is known. This comprises a processing plate and a processing plate holder, wherein the processing plate is perpendicular to a support surface of the processing plate holder in this releasably fixed.

Out DE 1 578 877 A1 Also, an edge processing device for skis with a replaceable processing plate is known. By means of an adjusting screw, the angle of the processing plate can be adjusted to the support surface.

Also the US 6,260,441 B1 shows an edge processing device with exchangeable processing plate, the angle is adjustable by turning an adjusting mechanism.

Based on the aforementioned prior art, the present invention seeks to provide a system for forming an improved edge processing device, wherein the system by a comfortable handling, in particular the Schleifwinkelvorgabemöglichkeit should be synonymous for laymen. In particular, the system according to the invention should facilitate the maintenance of a grinding angle. Preferably, different grinding angles should be realizable with the system with minimal changeover times. Further, the object is to provide an improved method for adjusting the grinding angle.

This object is achieved with regard to the system having the features of claim 1 and with regard to the method having the features of claim 12.

The invention is based on the idea of a machining plate for material-removing machining of the longitudinal edges of skis and / or Associate snowboards a machining plate holder on or in which the machining plate is releasably fixed, the machining plate holder on the one hand for ease of handling a tangible with the human hand grip portion for extending the edge processing device along the longitudinal edge of a ski and / or a snowboard and on the other hand a support surface having support section, which is designed and arranged such that the support surface rests along the ski and / or snowboards on a surface side of the ski and / or snowboard when pulling the edge processing device and thus the angular position of the angle to the support surface extending machining plate to the edge and thus the Grinding angle defined. The processing plate can be fixed in or on the processing plate holder such that a working section of the processing plate which offers a processing surface (abrasion and / or rasp surface) projects beyond the support surface of the support section in the direction of the support surface of the ski and / or snowboard, so that the working section, In particular, the working surface of the working portion with the support surface spans an angle defining the grinding angle, so that the support surface rests on the surface side of the ski or snowboard and the processing surface on the longitudinal edge (longitudinal side) of the ski or snowboard. In this case, the grinding angle corresponds to 90 ° less the angle between the working surface and the bearing surface. An essential idea of the invention is that the processing plate is only releasably fixable in or on the processing plate holder to exchange the processing plate and / or, as will be explained later, the processing surface (abrasion and / or rasp surface) renew.

The inventive design of the edge processing device makes it possible to use different processing plates with one and the same processing plate holder, with which different Grinding angles can be realized by the processing surfaces of the different processing plates with the support surface include different angles.

The system according to the invention therefore comprises at least two processing plates, i. a first and an at least one second processing plate which, when inserted into the processing plate holder, subtend a different angle with the support surface of the processing plate holder, i. define a different grinding angle. This is achieved according to the invention in that an angle between a processing surface and a rear side of the first processing plate facing away from the processing surface differs from the corresponding angle (between processing surface and rear side) of the second processing plate, in particular by at least 0.5 °, very particularly preferably by at least 1 °, more preferably at least 1.5 ° or at least 2 °.

The trained according to the concept of the invention system thus does not allow the adjustment of the angle by the provision of comparatively complex stepless adjustment mechanisms, which is preferably omitted in the further development, but by the selection and use of a processing plate that defines the desired angle. In this respect, as explained, the system thus comprises at least two different machining plates from which the user can or must select for setting or fixing the grinding angle.

It is also conceivable that the angle is selected from a value range between 90.5 ° and 100 °, in particular between 91 ° and 95 °, even more preferably between 92 ° and 95 °. According to the invention, the processing plate holder is assigned at least two different processing plates, in which one of the aforementioned two angles differs.

With such a rasp plate larger unevenness of the longitudinal edges of skis and / or snowboards can be compensated. Preferably, both tooth flanks of the teeth, preferably inclined at different angles of inclination in the same direction.

With a view to optimized handling of the edge processing device, it is particularly preferable if the handle portion of the processing plate holder supports the support portion on one of the support surface projected on the opposite side in order to exert a contact pressure on the support portion during the grinding process, and at the same time to press the entire device laterally against the edges can, while the device is moved along the edge. Most preferably, the grip section, in particular a center plane of the grip section extending along a longitudinal edge of a ski or snowboard, encloses an angle of at least approximately 90 ° with the support surface.

The latching means 9 comprise a latching lug 10 arranged on the processing plate holder 2 and projecting downwards and laterally elastically pivotable, which cooperates with a corresponding latching recess 11 of the processing plate 4.

The machining plate 4 is accommodated within the receptacle 3 in such a way that it does not move or only minimally displaces during the machining of ski edges or snowboard edges. For this purpose, the receptacle upwards and both longitudinal directions and both side directions offers support surfaces. Down the freedom of movement is limited by the locking means. 9

The processing plate holder 2 comprises a flat support portion 12, the underside of which defines a flat support surface 13, with which the device 1 rests on a surface side of the ski or snowboard during the processing of ski or snowboard edges. The support portion 12 is surmounted above by a handle portion 14, within which the recess 3 is formed for receiving the processing plate 4. The grip portion 14 includes approximately with the support surface 13 an angle γ of 90 °. On the side facing away from the handle portion 14, the support surface 13 is downwardly, i. in Auflagerichtung dominated by the recorded in the receptacle 3 there detachably on the locking means 9 fixed machining plate 4, more precisely of the abrasive carrying working portion 15, which serves for direct material-removing interaction with the edge of the ski or snowboard. The working section 15, more precisely the working surface 8, closes with the bearing surface 13 at an angle γ of 86 ° in the exemplary embodiment shown.

In order to achieve this angle γ, the machining surface 8 closes with a support surface 16 of the machining plate holder extending in the insertion direction E 2 an angle α (see. Fig. 4 ) of 4 °. The same angle α with this support surface 16 includes the receiving surface 8 for receiving the abrasive 7. A rear side 17 of the carrier plate 5 is supported on the support surface 16, the rear side 17 and the receiving surface 6 arranged on the front side remote therefrom likewise enclosing the angle α of 4 °.

The angle α of 4 ° is provided as a marking 18 on a front side of the machining plate 4. The area with the marking 18 is thereby recognizable by a corresponding recess 19 in the handle portion 14. The recess 19 is in the embodiment shown approximately at half the length of the longitudinal extent of the handle portion 14th

For reasons of stability, a reinforcing plate section 20 is provided on the side facing away from the support section 12 side of the handle portion 14, which is arranged in a plane with the support portion 12 and with the support surface providing support wall 21 forms an angle α of 90 °.

As it turned out Fig. 2 results in two longitudinally spaced chip outlet openings 22 are provided in a transition region between the support portion 12 and the handle portion 14.

Instead of the multi-part machining plate 4 with replaceable abrasives 7 shown in the figures, machining plates can be used with integral abrasives. It is also possible to provide metallic rasp plates which, preferably have tapered cutting teeth.

In the figures, only a part of the system is shown. It lacks the preferably provided further processing plate, which differs from the one shown Machining plate with respect to the angle α between the processing surface and the side facing away from the processing surface rear side.
