Abstract

The prolongation part (1) for the front end of a ski (2) is so formed that in side view it is curved in its attachment to the blade (2a) of the ski. In plan view, the prolongation part is wider than the ski, particularly its blade. It extends the ski upwards and particularly forwards. In side view, the prolongation part can have no curvature and can be connected only with the straight free end of the blade.

Description

I. Field of application

The invention relates to an attachment part for the front end of skis.

II. Technical background

A problem with skis is that the design, especially the so-called Fitting, i.e. width of the ski in the supervision and its changes in the length range, depending on the surface, especially in the front area, that is the shovel, should theoretically be very different:

With loose deep snow, as is especially the case on touring descents the front end of the ski should protrude as far as possible above its tread, to make the moving ski float on the surface of the loose Favor snow and immerse yourself in the snow as much as possible avoid. For the same reason, the widest possible width of the front, protruding, end of the ski desirable.

For driving on normal, groomed, slopes with comparatively hard Underground in which there is no fear of sinking in, this is not necessary, On the contrary, it is even a hindrance, since z. B. Overlap the skis Moving back to the parallel state becomes difficult and too wide the ski in the front area hinders tight parallel skiing.

It should also be noted that it has been in the past was known to ski touring in the event of a ski tip break, usually a breaking off of the shovel of the ski, a spare part in the form of a broken off one Carrying a ski-mounted shovel. This replacement shovel consisted of an aluminum sheet metal part and was designed so that it was only on a broken end of a ski that is just coming out, but not on one still existing, curved in the side view, shovel could. This replacement shovel was also not used to extend the shovel upwards or broadening them, just creating an equal wide and equally high shovel compared to the originally existing broken shovel.

III. Presentation of the invention a) Technical task

It is therefore the object according to the invention, a neck part or a set To create skis and attachments so that a normal one, so for preferably skiing on slopes of dimensioned skis, as he generally sells today and is used, by means of the extension part in its upward extension and / or is broadened.

• im montierten Zustand die während des Fahrbetriebes auftretenden Belastungen aushalten, vor allem was die Befestigung des Ansatzteiles am Ski betrifft,
• die Montage des Ansatzteiles am Ski einfach und schnell und auch unter widrigen Verhältnissen im Tiefschnee auf der Piste durchführbar sein und
• der Transport des Ansatzteiles einfach möglich sein, also mit geringem Raumbedarf, geringer Beschädigungsgefahr und geringem Gewicht des Ansatzteiles.

Such an approach part must be for practice

• in the assembled state can withstand the loads that occur during driving, especially when it comes to attaching the attachment part to the ski,
• the attachment of the attachment part on the ski can be carried out quickly and easily and also under adverse conditions in deep snow on the slopes and
• the attachment part can be easily transported, ie with a small space requirement, little risk of damage and low weight of the attachment part.

Another problem is that the attachment part depends on the manufacturer and ski model of differently dimensioned front ends of the skis, in particular the blades, must fit.

b) solving the problem

This object is achieved by the characterizing features of claim 1. Advantageous embodiments result from the subclaims.

Because the attachment part can be attached to the shovel of the ski, it can used to extend and / or widen an intact, undamaged ski become.

In particular, an attachment part can be put together and thus with regard to dimensioning made and sold to fit a specific ski.

Due to a wider outer dimension, especially the tread, the attachment part towards the widest part of the ski and especially its Shovel, the maximum width of the ski is increased overall and thus the Track width pulled in deep snow by the shovel of the ski and by the rest of the ski can be used.

By protruding the attachment part over the ski tip up and thus in As a rule, driving forward in loose snow is also a bit forward Probability increases that the top of the set, namely the top of the Attachment part, is still above the snow surface while driving and through the sloping tread of the attachment part so that the ski when driving floating on the loose snow. The undercut and thus piercing the tip of the ski in loose powder is prevented.

For this purpose, the attachment part can be straight, viewed in the side view and is then only with the free end of the Shovel of the ski connected.

Another possibility is that the neck part in the side view is also curved, and in particular the curvature corresponds to the curvature of the blade of the ski, and also the attachment of the attachment part on the blade in the region of the curvature of the blade.

The one in the shovel as well as in the attachment part and if possible Matching curvature is then used for a positive connection between used these two parts.

The attachment part attached to the ski preferably ends on the underside of the ski still in the area of its blade, and does not extend to the bottom, essentially flat, horizontal area of the tread of the ski. Thereby ensures that the vehicle can be driven on without problems even when the extension part is installed a hard slope with the ski is possible.

The extension part itself can be in one piece or two with respect to the longitudinal center of the Ski and thus also the attachment part preferably largely symmetrical trained halves. At its rear end facing the ski the attachment part will have an opening for inserting the blade of the ski, and can be opened for this purpose in the transverse direction, in particular bent apart either with a one-piece attachment part due to the Material elasticity in the connection area or with a two-piece design due to a flexible, articulated connection, which then z. B. by means of a Spring is biased in the contracted state.

In order to create a connection between the attachment part and the ski that is as secure as possible, encompasses at least the outer part of the underside of the ski, the outer narrow side and part of the top form-fitting.

In the case of an articulated connection between two separate side parts, the articulation is preferred designed to be separable, and in particular as a closure of the two Side panels against each other. By separating the joint, the side parts can can be separated from each other and thus transported individually and in a space-saving manner become. For this purpose, the design of the side parts in particular is chosen so that that they are at least partially nested to save space for transportation can be. In particular, the individual side parts in Cross section of a U-shape or V-shape, so that at least the corresponding ones left side parts and the corresponding right side parts, preferably also the left into the right side part and vice versa partially or can even be plugged into each other.

As a closure of the two side parts to each other and / or as a closure of the A Velcro fastener is preferably used opposite the ski.

Another possibility is - especially if the attachment part is designed in one piece - A positive hole / pin connection, in particular in one Hole on the longitudinal central axis of the ski, in particular a through hole through the ski, and one engaging in this hole from below or from above Pin of the extension part is made. The tenon can be divided into two halves be the two side parts, with one-piece as well as with two-piece Training of the attachment part are assigned. The pin snaps into place the hole may be possible due to the material elasticity of the attachment part, which is produced, for example, as a molded plastic part.

In the case of a two-piece design, the side parts can also be made from an extruded aluminum profile produced in a U-shape and, for example, with the necessary curvature.

The connection point is sufficient, in particular if the attachment part is formed in one piece between the two sides of the extension in the tread backwards than in the top of the neck part. However, it is possible that this junction in the tread before the front end of the The scoop of the ski ends and thus on the longitudinal central axis in the tread The opening between the attachment part and the ski is created, but then only in particular is shaped as a narrow slot.

The connection point in the tread can in particular also be a thin-walled one Bulge of the tread can be formed downwards, which is due to the Bending outwards allows the neck part to be easily deformed.

In addition, a fin can be formed on the underside of the attachment part, that runs lengthways, and especially breaking up a hard surface of the subsurface with underlying softer layers. The Finn preferably runs in the longitudinal direction and is either on the Longitudinal center of the attachment part, or symmetrical to this in double training left and right of the attachment part. The Finn usually does not get higher than about Protrude 1-3 centimeters from the underside of the attachment part, and at start at the foremost end of the attachment part, and also near the foremost end have their greatest height, and become lower towards the rear, in particular leak before the rear end of the extension. In cross section can the fin has the shape of a vertical plate with approximately the same Have wall thickness, or also V-shaped with increasing cross section to Approach part, especially the transitions between fin and attachment part strong are rounded to improve stability. Furthermore, such improves Of course, the Finn runs straight on the skis, especially in the loose Deep snow.

Fig. 9: a near-series embodiment

In the following figures, the views from below and above (Fig. 2 and 3) each shown in Figures 2a and 3a attachment parts that the ski over essentially only extend the front end while the figures 2b and 3b show variants which show the ski in relation to its widest point 16, which is usually in the scoop, also widen.

• in der linken Bildhälfte das Ansatzteil maximal bis zur breitesten Stelle 16 der Schaufel 2a des Ski 2 nach hinten reicht, dagegen
• in der rechten Bildhälfte das Ansatzteil 1 über die breiteste Stelle 16 hinweg nach hinten reicht, so dass allein durch dieses Umgreifen der breitesten Stelle bereits ein Formschlusseffekt zwischen Ski 2 und Ansatzteil 1 erzielt wird.

In addition, two different variants are shown in the left and right halves of the picture in that

• in the left half of the picture, the attachment part extends to the widest point 16 of the shovel 2a of the ski 2 to the rear, however
• in the right half of the picture, the attachment part 1 extends backwards over the widest point 16, so that simply by reaching around the widest point, a positive locking effect between the ski 2 and the attachment part 1 is achieved.

In addition, the widening versions according to FIGS. 2b and 3b show that the widest point of the attachment part 1 is preferably in front of the tip of the ski 2 and the side edges of the attachment part 1 preferably without kinks and heels in the side edges or narrow sides 4 of the skis 1 pass over.

The views from below according to FIGS. 2a, b show that the attachment parts 1 the edge area of the running surface 9 of the ski adjoining the narrow sides 4 only overlap relatively slightly, i.e. to a width of about 1 to 2 centimeters, so that the tread 9 of the ski is covered as little as possible by the in the Usually less well slidable underside of the attachment part 1. Nevertheless there is a cover the tread 9 through the underside of the attachment part 1 to the possible at the rear end.

The top views of the extension part according to FIG. 3 show that the tops of the - as best shown in Fig. 4 - each U-shaped in cross section Side part 1a, b except for a narrow distance or slot 17 reach against each other in the rear area, so that by means of a closure 8 the two side parts 1a, b of the attachment part are held together.

3a and 3b show the one-piece design of the attachment part 1, in which the side parts 1a, b in the front area via a connection point 6 are connected to each other, this connection point 6 only a fraction, a maximum of about 5 centimeters in the longitudinal direction 10, by bending the To allow side parts 1a, b to be pushed onto the ski 1, FIG. 2a shows the two-part variant:

The two side parts 1a, b are via a joint 7, in particular one Swivel axis, connected to each other in the front area of the attachment part, and preferably overlap somewhat in this area for this purpose.

The joint 7 is preferably in the side parts 1a, b against each other biased direction.

As a closure 8, which is preferably arranged on the top of the attachment part 1 is, any type of mechanical lock, but also a simple one Velcro can be used, which on at least one of the side parts 1a, b is fastened with Velcro and is easy to remove.

4 shows the two U-shaped halves in the cross-sectional illustration of the two side parts 1a, b of the attachment part 1, the inner free space dimensioned so is that it is around the outer area of the ski 2, that is, the edge area thereof Tread 9, the narrow side 4 and at least part of the top 5, can reach around.

4 shows a snap lock in which one Latch 18 is pivotally attached to a side part 1a in a transverse plane and folded down into a position engaging behind a nose 19 of the other side part 1b can be after the two side parts 1a in the target position are attached to the ski 2.

The side view of FIGS. 1a and 1b shows that for taking the The target position must be handled differently, depending on whether that Side part 1 only on the front, in the side view straight or hardly curved end region of the blade 2a of the ski 2 is seated, as in FIG. 1a, or viewed from the side in the blade 2a as far back, that the attachment part 1 itself have a curvature in the side view must correspond to the curvature of the blade 2a, as shown in Fig. 1b.

While in the former case according to FIG. 1a, it is simply pushed open from the front top of the free front end of the blade 2a is possible with the second 1b the lateral attachment of the two side parts 1a, b the most sensible solution:

For this purpose, however, the two side parts have to cross on one greater distance than can be brought in the assembled state. This is possible in the two-part version by means of the joint 7 or in the one-piece Embodiment by a corresponding extensibility of the material of the attachment part 1 in the connection area 6.

For this purpose, the connection area 6 either consists of a very elastic material such as rubber, or the connection area 6 - As shown in Fig. 5 - V-shaped in the middle with the smallest possible wall thickness or arched in a U-shape, which facilitates stretching in the transverse direction if the material used for this is still sufficiently flexible, which is usually still the case with plastic.

5 also shows the two variants in the two outer areas, namely, that the insert part is bent twice in a U-shaped edge region can be, as is also preferred in the length range of the ski lying therein is, or can only have a simple offset, which the material requirement and thus additionally reduces the weight.

Fig. 6 shows - in the top or bottom view - also a positive type the fixation between attachment part 1 and ski 2, in which in the ski 2 - preferably on whose longitudinal central axis 10 - a hole 14 is provided, in which a pin 13 of the attachment part 1 engages. The pin 13 is preferably in two halves Partial pin 13a, b separated, one of which with the one side part 1a and the other is integrally formed with the other side part 1b is.

When the extension part is pushed on, these partial pins 13a, b snap into the hole 14, which can also be a through hole through the body of the ski, one and are held there due to the restoring force of the material of the attachment part 1. The pin 13 or the partial pin 13a, b can be from the lower part of the extension part protrude into the hole as well as from its top.

Fig. 7 also shows a variant in which the connection area 6 in this Case integrally formed attachment part 1 far before the front end of the ski is in the assembled state. Due to the correspondingly narrow design of the side parts 1a, b also in the lower part of the attachment part, i.e. the tread, arises between the two side parts 1a, b an opening 12 in the tread and thus preferably also in the entire neck part, preferably only in the tread is formed as a narrow slot, on the other hand in the top of the attachment part Significantly wider without problems, for example V-shaped from front to back can be designed to expand.

The manufacture of the attachment part 1 in a two-piece variant, that is, from two on the Connection separable side parts 1a, b allows for an overall U-shaped Cross-sectional design of these side panels especially the space-saving nesting in each other at least of the two corresponding side parts 1a and corresponding side parts 1b of two attachment parts 1 required for a few skis, as shown in Fig. 8.

In addition, these side parts nested in pairs by at least Partially pushing one another together to save space and partially into each other be accommodated by the long legs of the U-shape that are in the Usually form the top of the attachment part, so be placed against each other, that the cranked outer areas of the side part pairs point away from each other, and put the cranked outer areas into each other.

In addition, the solutions of FIGS. 1b and 2b show the possibility of a fin 20, which can be present in any design of the extension part. The fin 20 serves the cutting of a hard, harsh layer of snow, and must therefore be sufficiently sharp and stable on the one hand, on the other hand the fin 20 must be rounded to such an extent that injuries from the fin 20 excluded are.

The side view of Fig. 1b shows that the fin 20 at the foremost end of the Approach part 1 begins there very quickly the greatest amount of protrusion down reached from the bottom of the rest of the neck part 1, and from there to is slowly becoming flatter at the back. The fin 20 preferably extends only up to the area of the top of Ski 2, and therefore ends before the rear end of the approach part 1.

2b shows the arrangement of such a fin 20 on the longitudinal central axis 10. However, it is also possible to be symmetrical to one another on both sides of the longitudinal central axis to train two such fins 20 in each of the side parts 1a, b and even with one-sided training of the attachment part, and even the arrangement only a single but off-center fin 20 is possible.

Such a fin 20 can also be used in the near-series embodiment according to FIG Fig. 9a to c be present, the following compared to the previous designs Features:

The extension 1 is - except for the clamping screw 21 - in one piece, preferably as Injection molded part made of plastic.

The tread 9 "extends over the entire width of the attachment part 1, and not just in the edge areas for reaching under the ski while on the Top of the ski only a top 5 "of the attachment part 1 in the form of a Cross bridge extends with its two lateral ends in the tread 9th transforms. This transition area 22 is inclined so that the two Transition areas 22 run diagonally towards each other, accordingly the sloping outer edges in a ski tip in their front area. This serves to create the edges of a ski tip over a greatest possible length within this cross bridge 5 ".

Accordingly, the attachment part also preferably extends from the front tip of the ski just so far down and back that they have the curved blade area of the ski no longer reached.

Accordingly, the rear end of the top is located, i.e. the cross bridge 5 ", the attachment part 1 before the widest point of the ski shovel, ie in Area of the ski tip, which is usually straight up.

The tread 9 of the extension part 1 ends towards the rear preferably under the rear end of the cross bridge 5 ", but can also beyond be extended, preferably only in the central area, in the form of a behind the tread of the ski continued tail extension 23 to the System length - along the longitudinal central axis 10 - between attachment part 1 and Ski 2 to enlarge and thus improve the connection.

The attachment part is attached to the ski 2 by means of a clamping screw 21, which by above through a threaded hole of the cross bridge 5 ", preferably in the middle is screwed in and is supported on the top of the ski, preferably there engages in a small recess in the form of a blind hole, and when tightening the clamping screw thus the tread 9 of the extension 1 against the tread the ski tip pulls.
