Definitions
- the present invention relates to a device for adjusting the pretension or deflection in snowboards or skis and the use thereof on a snowboard or ski.
- Skis in particular snowbards, are inherently stable due to the special structure of different layers of wood, plastic and metal due to deflection and torsion. With today's designs, it cannot be adapted to the needs of the driver. The snowboard loses quality when used intensively, i.e. the preload or deflection decreases.
- the object of the present invention is to provide a device having a variable and spring-A * - stallbarkait the hardness (stiffness) of the snowboard or skis allows tailored to the needs of the driver according to its weight, its ability and jeweili ⁇ gen Snow conditions to to enable an optimal use of edges. It is also intended to dampen the impacts on the driver's body when driving, to reduce undesirable vibrations to improve the driving properties and to increase the life of the snowboard as far as possible.
- a device 1 which is, according to the invention, distinguished by two ir. Spacing from one another * ⁇ f the top of a snowboard or ski, abutments to be attached upwards, by means of a pressure rod arranged between the latter rests on one abutment and is guided freely longitudinally in the other, a stop being provided on the push rod in its central region and a spring and / or damping element being arranged between this and the abutment guiding the push rod 1 ngsverschi ebl i ch which can be preloaded to a greater or lesser extent by changing the distance between the stop and said other abutment and by means for freely adjusting the distance between said other abutment and the stop such that the two abutments are pretensioned by the spring and / or damping element are pressed apart with an adjustable force and thus impose a more or less pronounced deflection on the base, ie the snowboard or ski in the area between the abutments.
- a particularly advantageous embodiment of the subject matter of the invention is characterized in that the push rod is formed in at least one portion as a threaded rod with a stop nut which forms the abovementioned stop, the push rod, which is preferably secured against rotation, being longitudinally displaceably guided in an abutment and rests with a stop surface on the other abutment and that a compression spring and / or a damping element is placed on the pressure rod between the adjusting nut 1 forming the nut 1 and the length-displaceably held end of the push rod, wherein the push spring and / or damping element can be preloaded by adjusting the adjusting nut to any value that can be set as desired.
- an eccentric or wedge mechanism acting on the spring and / or damping element and attached to the push rod can also be used as the element.
- the adjusting means consist of a device with which at least one of the abutments is adjusted in the direction of the longitudinal axis of the push rod. The spring and / or damping element is thus also more or less pretensioned.
- At least one such device is attached in the area between the bindings on the top of the snowboard, but possibly several next to one another, whereby the devices can be of different types (e.g. one with a spring element, the other with a damper element).
- the device When used on skis, the device must be installed lengthways in the area of the binding plate (possibly slightly thicker).
- FIG. 2 shows a snowboard equipped with an element 1 device according to the invention in a schematic plan view
- Fig. 3 is a view similar to Fig 2, with two differently constructed, side-by-side adjustment devices.
- Fig. 4 is a side view of an inventive device also purely schematic.
- FIG. 6 shows a particularly preferred embodiment of a device according to the invention.
- Fig. 1 of the drawing shows a schematic longitudinal ⁇ section through a snowboard 1.
- the running surface of the snow ⁇ boards 1 generally has a predetermined mean bias which in the deflection f mani ⁇ festiert, ie the tread with unloaded board is concave.
- the deflection f. the tread can be changed (to any value f.> f Q ). That changes the
- Driving characteristics or the basic tension due to material fatigue, which is reduced by use or aging, can be adjusted. Such an adjustment can of course also be used to match the individual weight or the skill of the driver.
- any shocks that occur can be damped more effectively than if only one spring element is used.
- FIG. 2 of the drawing shows a top view of a snowboard 1 equipped with a device according to the invention.
- the device 1 with the two abutments 2,2 'projecting upwards, the push rod 3, the adjusting means 4, the spring element 5 and the damping element 6, is arranged in the section between the two bindings 7, 7 '.
- the device consists of the two angles 2,2 'forming the abutment, which are firmly connected (screwed) between the bindings 7,7 * with the board 1 and a threaded rod 3 forming the push rod (this points at least in the middle section has a thread).
- a threaded rod 3 On the threaded rod 3 there is an adjusting nut 4, a compression spring 5 and a damping element in the form of a rubber block 6.
- the preload of the compression spring 5 and the damping element 6 can be varied and thus the preload or deflection f, of Boards are influenced.
- this arrangement with compression spring and damping element there is a dependency between the characteristics of these two elements.
- the device it is also possible for the device to have only one compression spring or only one Damping element is equipped. However, both elements are preferably arranged on a push rod. It is also possible to provide several devices of the same or different construction on a snowboard.
- 3 shows a snowboard with two devices 8 and 9 arranged next to one another, one of which carries a spring element 8 'and the other a damping element 9'.
- one device 8 is used to adjust the deflection of the tread, while the other 9 is mainly used to adjust the degree of damping.
- FIG. 4 shows the basic structure of a device according to the invention. This consists of two abutments 10, 11, a threaded rod 12, which rests with a shoulder 13 on the abutment 10, and a compression spring
- the threaded rod 12 is axially freely displaceable in the abutment 11, but is preferably secured against rotation at this end.
- the board 16 are more or less pretensioned so that the two abutments 10, 11 are pressed apart by the pretensioning force and, thanks to the lever formed by the abutments 10, 11, the board is more or less pretensioned or bent.
- abutments 10 can be fastened to the board in a slide-like guide 10 ', the abutment 10 in the guide 10' being able to be displaced by means of a suitable adjusting device (for example also a threaded rod) to instead the adjusting nut 14 (which would have to be replaced by a fixed stop) spring and damping element 15 or
- a suitable adjusting device for example also a threaded rod
- FIG. 5 shows, purely schematically, a further adjusting means in the form of an eccentric 17, which can rest against the fixed stop 18 (instead of screw 14) on the rod 12 and move it.
- the eccentric 17 in the form of an eccentric 17, which can rest against the fixed stop 18 (instead of screw 14) on the rod 12 and move it.
- FIG. 6 of the drawing shows a particularly advantageous embodiment of the subject matter of the invention.
- a three-part push rod 1 ', 19 ", 19"' is rotatably mounted (in the bores 17 'and 18'), with one end of the push rod in the bore 17 'also 1 ngsverschi eb- 1 i ch).
- the stop 20, against which the compression spring 21 rests at one end, is seated on the section 19 'of the push rod which is designed as a threaded rod.
- the other end of the compression spring 21 bears against the end cover 23 of a tube 22 surrounding the pressure rod 19 '.
- This tube 22 bears against the abutment 17 and ensures that the two abutments 17, 18 are pushed apart to a greater or lesser extent depending on the tension of the spring 21 (the spring naturally also absorbs changing forces during operation of the snowboard without them) but to dampen significantly).
- the displaceable stop 20 has a threaded bore and is seated on the thread of the push rod section 19 '.
- the stop (threaded sleeve) 20 is guided in a longitudinal slot 25 of the tube 22 via a radially projecting pin 24, so that by turning the threaded rod 19 the stop 20 can be adjusted (and thus the spring preload) while holding the tube 22 at the same time.
- the position of the pin 24 in the slot 25 also indicates the spring preload.
- section 19 '' of the push rod 19 which is rotatably connected to sections 19 'and 19 "' (section 19 'is inserted in section 19" in a rotationally fixed manner, while section 19 "is designed in one piece or screwed to section 19"') serves as a support for a damping
- a rubber element 29 is inserted between a shoulder 26 and a threaded sleeve 28 placed on a thread 27, the shoulder 26 and rubber element 29 being inside the cylindrical tube 22.
- the last section 19 ′′ of the push rod is greatly expanded in diameter (corresponding to the diameter of the tube 22) and has a corrugated surface. This allows the pretensioning of the push rod to be twisted while holding the tube 22 at the same time Adjust the compression spring 21. It may be useful to loosen the threaded sleeve 28 for this item 1 process and then tighten it again in order to regulate the desired damping.
