Abstract

The snowboard binding has a base element (3) fixed on the surface of the board and an instep and heel element. The heel element (14) is attached so that it can swivel backwards into a step-in position lying substantially parallel to the surface of the board. With the instep element (5,6) fixed, the boot (2) can be inserted into the binding. Operating devices (15) swivel the heel element forwards into a predefined closing position where it is held to support the boot and press against the instep element. The operating devices have a first strap (15) fixed either side on the front of the base element to engage round the heel element on the outside. A second strap fixed on the upper part of the heel element is connected to the first strap so that tensile force acting on the second strap slides the first strap along the outside of the heel element towards the free end and thus swivels the heel element into the closing position. The position of the heel element can be adjusted by changing the length of the first strap.

Description

The invention relates to a Snowboard binding with a on the surface of the Basic element to be attached to snowboards, one attached to it attached to the top of the snowboard boot partially overlapping instep element and one the base element pivoted, the back the heel element supporting the snowboard boot, wherein the heel element (14) is articulated so that it in a substantially parallel to the snowboard surface lying entry position swivels backwards where the snowboard boot (2) is fixed Instep element (5, 6) can be inserted into the binding. Such Snowboard binding is known from WO-A-95/33534.

This snowboard binding has a basic element on which a partially overlapping the top of the snowboard boot Instep element is attached. Furthermore, on the Basic element that supports the back of the snowboard boot Heel element pivotally attached. In a The heel element is essentially the starting position pivoted backwards parallel to the snowboard surface, while with the binding closed, the heel element in protrudes substantially vertically from the snowboard and the Boot shaft supports.

From DE-GM 89 02 125.8 and DE-GM 91 13 766.7 Bindings known as "shell binding" or "soft binding" be designated. These bonds are for that intended to be used with relatively soft boots and have a high degree of flexibility, as is the case with the so-called freestyle riders is desired.

These well-known bonds have a basic element that is on top of the To fix snowboards is and usually there is screwed on. On the sides of this wall Basic element is an instep element attached to the the known bindings from one or more adjustable Instep strap that covers the forefoot and instep reach over and thus the boot down against the Press the base plate. These known bindings also show a support or heel element that can be pivoted to the attached laterally raised walls of the base element and supports the back of the boot and the heel and at the same time allowed a certain angle of inclination adjust the so-called submission of the lower leg Are defined. With these known bindings this can be done Heel element, which in practice in normal driving position protrudes about 20 to 30 cm from the snowboard surface, fold forward towards the instep element, so that it does not interfere with the transport of the snowboard. At the two known bindings allow the angle of inclination adjust the instep element for the driving position.

A similar snowboard binding, but with a fixed one Heel element, is also from FR 2 627 097 A1 (Fig. 9) known.

With all these known snowboard bindings, this is done Opening and closing the binding only on the instep element, what especially getting into the binding is very cumbersome designed. For example, in DE-GM 91 13 766.7 two instep straps opened and held open by hand so that the boot from above into the binding can be introduced. Because the heel element normally The boot must define a certain template if he is placed on the base element, still to the rear towards the heel and then finally the instep buckles are to be closed. The bond must with every new boarding, such as after every lift ride is required for the rear binding readjusted as the instep straps are always complete opened and no predefined closed position to have. In this whole process, the driver has to follow bend down and the instep straps with his gloves thread in buckles, what with icy binding not always succeed. Seen overall, these are known bindings quite cumbersome and uncomfortable in handling.

The object of the invention is the snowboard binding improve the type mentioned in that the Boarding and alighting is considerably simplified and after each time the binding is closed, a clearly predefined one Close position of all elements of the binding with very little Effort is taken again.

This object is achieved by the specified in claim 1 Features resolved. Advantageous configurations and Developments of the invention are the subclaims refer to.

With the snowboard binding according to the invention this can be done Heel element in an open position to the rear open up so that the boot slants with a forward / downward movement, which is essentially the corresponds to the natural pivoting movement of the knee joint, can be inserted into the binding. The instep element forms a fixed tunnel and must be used during the Closing process can not be adjusted. It will only once individually adapted to the boot and then keeps always make this adjustment. When the boot is up to the stop is inserted against the instep element, the heel element flipped up by actuators, until there is also a predefined closed position has taken. This predefined closed position also includes a preset template. Because of this Folding up the heel element turns the boot into something Extend further towards the instep element pressed so that the desired clamping force is applied becomes. With the invention you get with everyone Closing process a clearly predefined position of the binding. Furthermore, boarding is due to the natural Swiveling movement of the foot comfortably. The actuators for swiveling the heel element preferably formed by straps or straps so that a pointing upwards from the snowboard surface Pulling on one strap causes the entire closing movement. A cumbersome threading of belts or timing belts in locking buckles omitted.

Opening the binding is also very easy. Through a the actuator can be released in a simple manner be what the heel element in the open position is folded and the shoe is pulled out of the binding becomes.

The actuating device is particularly advantageous essentially from a first belt, the fastened on both sides to the front area of the basic element is and encompasses the heel element on the outside and from one second strap, the one at the top of the heel element is fixed and in connection with the first belt stands that pulling on the second belt will pull the first belt along the outside of the heel element towards its upper end stretches, causing the heel element is moved into the closed position. The closed position is reached when the second belt is pre-defined End position is reached. The template of the heel element can be adjusted by changing the length of the first belt become. That remains throughout this process Instep element unchanged.

The snowboard binding 1, each for fixing a Snowboard boot 2 is provided, has a basic element 3, which is fixed on the surface of the snowboard, for example by screwing in Fig. 1 this is Base element plate-shaped and essentially has on both sides Lateral protruding vertically from the snowboard surface Walls 4, each with an instep element 5 and 6 attached is. The instep elements 5 and 6 have the shape of padded Rags that are of the basic element 3 initially essentially protrude vertically upwards and then towards each other kinked are overlapping in a central area. This central area is at an angle to the Base plate 3 inclined so that it adapts to the instep form of Snowboard boots 2 adapts. The two instep elements 5 and 6 thus form a kind of tunnel, the height of which is forward reduced towards the tip of the boot. To the The instep elements are to be held in position lateral walls 4 tension plates 7 attached, which from a somewhat stiffer material such as B. plastic, around the instep elements 5 and 6 a certain lateral To give hold. At the top free end of the tension plates are Instep straps 8 and 9 attached under a guide loop 10 are threaded and - as further below in 4 is explained - with counter-belt the other side. The instep straps 8 and 9 are connected here by a loop 11 and thus form a continuous belt.

The instep elements 5 and 6 and the tension plates 7 are by means of Screws 12 and 13 on the side walls 4 of the Base element 3 attached. The two-sided Screws 13 also serve as a pivot bearing for Heel element 14, which is the actual closure element forms the bond and serves as a heel support. This Heel element 14 is curved in a bowl shape and fits the back of the boot. It is also padded. In the open position shown in Fig. 1 that is Heel element folded all the way back and almost lies parallel to the snowboard surface. So that's the one from Instep elements 5 and 6 formed tunnels from the back freely accessible so that the boot 2 by a simple Forward movement can be introduced into the binding. The instep elements 5 and 6 then guide the tip of the boot until the boot hits it in the is essential in its final position.

To close the binding, the heel element 14 must counter be pivoted upwards in the direction of arrow 20. An actuating device is provided for this purpose has a first belt 15 which is on both sides via a Loop 16 on the side walls 4 of the basic element is attached in the front area and that Heel element 14 wraps around the outside. In the open position this first belt 15 is loose and touches the outside of the heel element 14 in its lower, the snowboard surface nearby area. The length of this first belt 15 is adjustable by a belt buckle 17, through which the belt 15 is threaded and in one Loop 18 ends.

Around the first belt 15 always in engagement with the outside to keep the heel element 14 are on both outer sides of the heel element 14 loops 19 are provided, through which the belt 15 is threaded. These loops extend essentially over the entire length of the heel element 14 and can be provided with a Velcro fastener.

Another component of the actuator is a second belt 21 connected to the first belt 15 stands and in the upper area of the heel element 14 is attached to this by means of a tab 22. The Connection between the first belt 15 and the second Belt 21 takes place here via a loop, d. H. the belt 21 is from the tab 22 along the back of the Heel element 14 guided down, then wraps around in a loop the first belt 15 and then again led back up to a belt buckle 23, from which the second belt 21 then has a free end 24 protrudes, which is shaped into a loop. Becomes pulled at this free end 24 in the direction of arrow 25, thus shortens the loop formed by the first belt 15 loop and the first belt 15 slides along the outside of the heel element 14 up. This causes the heel element 14 to move upward pivoted and the belt 15 tightens. The complete one The closed position is reached when the belt 21 formed loop around the first belt 15 so has become short that the first belt 14 on the tab 22 comes into play. The bond is then closed with the length of the first belt 15 also the template, d. H. the angle of inclination of the heel element 14 is predetermined is. Since the second belt 21 is through the tab 22 predefined and thus clearly reproducible End position is also the closed position of the Heel element 14 clearly and reproducibly specified. When the heel element 14 pivots Boots even further forward against the instep elements 5 and 6 pressed so that there is a clearly defined one and reproducible pressure force prevails.

Fig. 2 also shows how the first belt 15 through the Guide loop 19 is guided and in their Can move longitudinally if necessary is. If this guide loop with a Velcro is provided, the belt 15 is only in its longitudinal direction slide through the existing opening of the Velcro fastener, but not in the longitudinal direction of the guide loop 19 postponed.

To open the binding, the buckle 23 is tilted, see above that the second belt 21 can lengthen and the first belt 15 a pivoting of the heel element 14 in the direction of Arrow 20 of FIG. 1 allowed. The shoe can then without further pulled back out of the binding.

Fig. 3 illustrates the setting of the template, i. H. the adjustment of the angle of inclination of the heel element 14 opposite the snowboard surface. The belt 15 is through a belt buckle 17 threaded, which in turn has a short belt loop 36 through an opening 37 in the side Wall 4 is threaded. By pulling on the loop 18 in Direction of arrow 26 can be the effective length of the belt 15 shortened, can be extended by loosening the buckle 17. This allows when the second belt 21 in its is predefined closed position, the template of the Heel element 14 and also the force with which the Snowboard boots forward against instep elements 5 and 6 is printed, adjust. In principle, this setting only be made once to bind to the individual shoe and does not need later to be changed more unless the driver wants to the template and / or the noticeable "hardness" of the binding change.

4 illustrates the setting of the instep elements 5 and 6. On one of the tension plates, here designated 7 ' is, two belt buckles 27 and 28 are attached via short belt loops 29 and 30. The belt sections 8 and 9 are each through one of the belt buckles 27 and 28 threaded and connected to each other by the loop 11. If the loop 11 is pulled in the direction of arrow 31, this shortens the effective length of the instep straps 8 and 9, with which the instep elements 5 and 6 overlap further and make the bond "closer". Conversely, by slight tilting of the buckles 27 and 28 the effective Length of the instep straps 8 and 9 can be increased. Both Settings are therefore infinitely possible.

5 shows the heel element 14 in more detail with a convex, elongated body a relatively rigid insert 34 and one covering it Upholstery 35. In the front, lower area - based on the normal operating position - is a hole on both sides 32 provided, through which a screw 33 is inserted can, which forms the pivot bearing 13 at the same time. From starting from these bores 32 is an approximately semicircular one Cutout 36 removed (see also FIG. 1), which enables that the heel element 14 can be folded far down can and at the same time allows a heel part of the Boot sole protrudes from the binding, which is best can be seen in Fig. 3. In the upper, facing outwards Part of the heel element is the tab 22 attached, by which the belt 21 is held. On both sides the heel part 14 is in each case one of the guide loops 19 attached and, if necessary, the Velcro 37. This Velcro fastener can be attached to an additional strip 38 be attached from plastic.

Fig. 6 shows different embodiments of the Basic element 3. This basic element is shown in FIG. 6a from a flat plate 39 which on both sides to the lateral walls 4 is bent up at right angles. The side walls 4 are sloping towards the front inclined and each have holes 40 and 41 for receiving the screws 12 and 13 (Fig. 1). Furthermore is before a bore 42 is provided on both sides of the bore 40, for threading the belt 36. As per itself from DE-42 19 036.3 A1 known, the base plate 39 has a circular central opening into which a disc 43 can be inserted which is an edge overlapping this opening owns. The disc 43 also has four elongated holes 44, with which the disc 43 and thus the entire binding can be screwed onto the snowboard surface. The Base plate 39 and thus the entire binding can rotate relative to disc 43 so as to adjust the angle of the binding stepless in relation to the direction of travel of the snowboard to be able to adjust.

6b shows a slightly different variant of the base plate 39, which differs from that of FIG. 6a in that that instead of the circular opening and the disk 43 four elongated holes offset along an arc 45 are provided with which the base plate 39 also can be attached to the snowboard. You can then but only twisted to the extent that the Length of the elongated holes 45 is specified. For one The screws would then have to be twisted further completely removed and new in other places be used.

6c shows a further variant. Here is the base plate divided into two angular elements 46 and 47 which are mirror-symmetrical to each other and also the have side walls 4. The parallel to Legs 48 lying on the snowboard surface have bores 49, with which these elements also on the Snowboard surface can be attached. The rest Holes or slots 40, 41 and 42 correspond to that Embodiment 6a. About these holes or slots the remaining parts of the bond to these basic elements 47 and 48 attached.

Fig. 7 shows blanks for the manufacture of the instep element according to a variant of the invention, in which the instep element is better adapted to the shape of the instep of the boot and so that forces from the driver's foot better on the front edge of the snowboard can be transmitted. For the production of the instep element 50 are three parts 51, 52 and 53 used. The first part 51 is an elongated one Strip that covers the area of the toes of the boot (see Fig. 8). This stripe is on his toes facing edge 61 slightly curved outwards, i.e. convex arched and at its opposite edge 56 after inside, i.e. concave and within one Middle section, indicated by two dashed lines is limited. Outward from these dashed lines the strip 51 has straight edge sections 54.

The second strip 52, which is the midfoot area of the boot covering (see FIG. 8) has the strip 51 on it facing edge also initially the straight line Sections 54, the length of which is equal to the length of the sections 54 of the strip 51. Here is the end of the rectilinear sections 54 by dashed lines marked. The middle area of the edge between these dashed lines, i.e. the edge 57 is on the inside, i.e. concave, the curvature of the edge 57 more pronounced is, i.e. has a smaller radius of curvature than the edge 56 of strip 51. The two strips 51 and 52 are attached to each other at edges 54, 56 and 57, for example sewn. The two sides 60 of the strip 52 are also curved inwards.

The third stripe 53 covering the instep of the boot (see Fig. 8) is similar to the middle Stripe 52 adapted, the opposite Edges from the outside in first a straight line Section 55 have the dotted lines is limited, with the strip 52 then following inside, concave section 58 connects while the strip 53 is slightly convex to the outside curved section 59 connects. The two stripes too 52 and 53 are along the edges 55, 58 and 59 with each other connected, for example sewn. The edges 55 and 59 of the strip 53 is the opposite edge 62 slightly convex outwards. Become the three stripes 51, 52 and 53 with each other in the manner described connected and then across the front of the boot bent, so you get the shape shown in Fig. 8 of the instep element 50, which optimally matches the instep and the Adapts to the forefoot and thus the load on the front edge of the snowboard, the heel of the boot lifting forces a large-scale distribution of forces allowed on the forefoot. This situation is shown in Fig. 8, in which the front edge of the snowboard 64 rests on a slope 65 while the heel 2 '' is raised is and the toe area 2 'of the boot pressure on the Front edge of the snowboard 64 brings.

The reverse situation, where the rear edge of the snowboard 64 rests on a slope 65 'and the Heel area 2 '' exerts significant pressure while the toe area 2 'is raised, is also shown in Fig. 8 shown. In this case the line of force runs from Boot shaft over the heel element 14, the belt 15 and the base plate 3, 4 to the heel area, the instep element 50 must absorb comparatively low forces and only prevents the boot from overall binding is tilted.

From Fig. 8 it can also be seen particularly well that the Belt 15 when the rear edge of the snowboard is loaded Forces from the top of the heel element 14 immediately on the front of the binding in the toe area 2 ' transmits and thus an immediate lifting of the toe area when the rear edge of the snowboard is loaded does what was not the case with conventional shell bindings.
