The present invention concerns bindings for snowboards, where the bindings come in pairs which are attached to fixation devices in the snowboard, and more particularly the present invention concerns how such bindings can be adjusted.

Because different snowboard riders have different types and sizes of boots, and also different riding styles, they have different wishes for how the binding on their board should be adjusted in order to provide the best riding experience for them. Almost all types of bindings allow for some adjustments of highback, binding straps etc. Most commonly the rider will loosen one or more screws with a screwdriver and then move and/or adjust one or more parts of the binding, and then tighten the screw(s) again, thus having made the desired adjustment.

An object of the present invention is to provide a binding for a snowboard which can be adjusted in an easy way.

It is further an object of the present invention to provide a binding for a snowboard which is economical and simple to manufacture.

These objectives are achieved with a binding for a snowboard provided with an adjustment system for straps on a snowboard binding according to the invention as defined in the enclosed independent claim, where embodiments of the invention are given in independent claims.

The present invention seeks new ways to achieve adjustments of the binding straps for the desired position on a binding frame of the binding without the need of a screwdriver or any other tools. The invention consist of the combination of 3 elements,

1. It is tool-less so the attachment position of the binding strap can be unlocked from one position on the binding frame and be locked into another position fairly easily with your bare hands,

2. It has a stable locking mechanism based on a profiled press in system, such as press-button / pin fitting or the like, into at least one hole with profiled shape provided in the binding frame of the binding where also at least one hole provided in the binding strap will fit in and be securely locked in when the press-button/pin is put in place, and 3. The press-button/pin is put in place from the inside and prevented from popping out during use also by the boot which blocks the only exit direction for the button, which is inwards.

One may assume that the press in system, for instance press-button/pin locking systems are less secure than screws. However, screws tend to come loose over time by vibrations during use, and the press-button/pin locking systems described by our invention takes measures to ensure the durability of the locking position. The one or more press-buttons that are used and the corresponding hole or holes in the binding have certain locking mechanisms by themselves, and in addition to that they are blocked from popping out while the boot is strapped in its normal riding position. This will prevent the locking-button from falling out during use, which is the most critical since it concerns the safety of the rider.

The press-button locking system of this making can be applied for both toe- straps and wrist-straps.

For wrist-straps the press-button/pin systems offers an additional safety feature against the press-button(s) popping out. The one or more press- buttons are put in place while the highback of the binding is moved forward from its normal position, i.e. a position where the highback is arranged to be resting on a heel stay of the binding. When the highback has been put back in place, it covers the press-button(s) and will prevent the press-button from falling out, even if there is no boot present, and the system is then further stabilized when the boot is being strapped tightly into the binding, allowing very little space for any movement of the press-button(s). Such a combined enhanced secure locking system at the wrist-strap is seen as clearly advantageous, and it only requires flipping the highback forwards, so it comes at no extra effort when changing the wrist-strap's position.

For toe-straps the press-button/pin systems may offer an additional safety feature against press-button(s) popping out. The hole or holes for the press- buttons/pins may be placed rather close to the bottom of the binding frame, arid the press-button(s) are then put in place while a floor plate of the binding is moved out from its normal position. When the floor plate has been put back in place, it covers partly the one or more press-buttons and will prevent the button(s) from falling out, even if there is no boot present, and the system is then further stabilized when the boot is being strapped tightly into the binding, allowing very little space for any movement of the press-button(s). Such a combined enhanced secure locking system at the toe-strap is seen as advantageous, even though it require the removal of the base-plate while adjusting the toe-strap's position. This solution may also require a slight modification of a base plate of the binding to make it cover a part of the press button(s) if the hole(s) cannot be placed low enough.

There are safety aspects with straps that the present invention does not address, like straps simply breaking, or buckles that opens during riding. The goal of the present invention is to secure the aspect where the changes occur relative to existing systems.

The straps themselves may be made as most straps are made in order to fit the position when they are closed in over the boot in order to lock the boot in this position. However, we find it beneficial to make a special profile in the straps which make them bend away from the bindings when open. The reason for this is to make it easier to put the bindings back on for the next ride, and especially it is easier for the rider to put his free boot in the binding while riding out of the ski-lift. Straps that bend outwards are known, but we here introduce a special profiled reinforcement of the strap which to a greater extent makes the strap stay in the desired position without having to use extra amounts of material. It is also a point that the straps must not be too strongly bent outwards, since when the boot is buckled in, the straps must fold nicely over the boot without causing problems because of its special shape. It is especially the wrist-strap which holds the wrist-padding that gives the most benefits to bend out, but also the wrists tooth-strap on the opposite side and the toe-straps can be bent out to allow easier access to the binding.

Generally about straps that are used in connection with bindings: each binding comprises usually four straps, corresponding left and right wrist- straps, and corresponding left and right toe-straps, whereby a pair of bindings then has 8 straps. Between a pair of corresponding straps is arranged a padding. One of the straps of the corresponding left and right wrist-straps and toe-straps will then be permanently fixed to one end of the padding (the strap may still be adjustable, but not adjusted every time the rider buckles in). On its opposite side, towards its end the padding has a buckle into which the rider puts the other corresponding strap and tightens it with the buckle. The strap which goes into the buckle is usually a tooth-strap in order to allow the buckle to tighten it. A person skilled in the art would know how the different straps and buckle should be designed, and this is therefore not discussed further herein.

An important element of the present invention is how the one or more holes in the binding frame and the one or more locking-buttons them self are designed to assure that they stay in position during riding. One aspect is the profiles of the press-button(s) being slightly larger than the corresponding hole(S) in the binding frame.

Another aspect that helps keep the press-button(s) in place is that one may make the radius of the press-button smaller than the hole just where the strap fits in. Then when the strap is tightened, it will keep the press-button(s) in place. The reduction in radius can be rather moderate and still achieve a significant difference. To prevent breaking issues, it is also an option that the core of the press-button(s), normally being made of plastic, may be made of metal.

The invention shall now be described further through a few of several possible examples which fit the above description. Whether one uses this system just for wrist-straps or just for toe-straps or for both on a specific binding is a matter of choice. Press-buttons/pins for more than 3 holes are also possible.

The foregoing and other objects, features and advantages of the invention will be apparent from the following more particular description of preferred non-limiting embodiments of the invention, as illustrated in the accompanying drawings where:

Figure 1 shows a top view of a prior art binding, where only a normally curved wrist-strap with a wrist-padding attached thereto is shown,

Figure 2 shows the binding with an adjustment system according to the present invention 1, where the wrist-strap is shown in an outwardly bent position,

Figures 3A-3E show different embodiments of a binding, where the binding is provided with alternative attachment point(s) for the wrist-straps and toe- straps, a cross-section of the attachment point(s) and inserted press-button(s) and a top view of the press-button(s),

Figure 4A shows a view of an embodiment of a binding with right side wrist- strap and right side toe-strap, where the binding frame is provided with two different attachment points available for the wrist-strap and three different attachment points for the toe-strap,

Figure 4B shows, from above, a rear part of a binding, where the wrist-strap is attached to a trailing position of the attachment points available for the wrist-strap by press-button(s),

Figure 5A shows the general profile for a single press-button of the press- button system seen in side view (left) and from the top (right). The profiles will be the same for press-buttons provided for two holes and press-buttons provided for three holes. A press-button for two holes may also fit the binding frame that is provided with three holes,

Figure 5B shows the press-button according to figure 5A, before it is pressed in to the shown position with the straps also in position,

Figure 5C shows the press-button according to figure 5A, after it is pressed in to the shown position with the straps also in position

Figure 5D shows the press-button according to figure 5A, with the highback or base-plate in position, preventing any pop-out of the press-button

Figure 5E shows how to press the press-button according to figure 5A out after first tilting the highback away or removing the base-plate,

Figure 6A shows the special profile of a wrist-strap or toe-strap, for instance the wrist-strap according to figure 2,

Figure 6B shows the strap according to figure 6A, from the side view with marks for different cross-sections,

Figure 6C shows three different cross sections of the strap according to figure 6A, where the amount of angle on the profile used will depend on material and thickness of the strap, here is just shown one possible making, and Figure 7 shows much the same as figure 5, only with a different making of the press-button.

In figure 1 is shown a prior art binding B for a snowboard (not shown), where the binding comprises a binding frame 1, a base plate 2 and a traditional wrist-strap 3, It is also indicated that the binding frame 1 is provided with holes 6 for attachment of a toe-strap (not shown). One end of a wrist- padding 1 1 is in a suitable manner connected to the wrist-strap 3, while the opposite end of the wrist-padding 11 is connected to a buckle 9. The buckle 9 is used to connect a corresponding wrist-strap (not shown) with the wrist- strap 3, whereby the two wrist-straps can be adjusted and locked relative each other.

As can be seen, this prior art binding will provide a strap system where the wrist-strap when not in use, will fall into the binding frame 1. This will result in that it will be difficult to set a boot into the binding B again, without removing the wrist-strap 3 from the binding frame 1.

In figure 2 is shown a binding 20 according to the present invention, where the binding 20 also is provided with one or more holes 6, 7 for a pair of corresponding toe-straps (not shown) and a pair of corresponding wrist-straps (only the right hand wrist-strap 3 is shown), where the wrist-strap 3 is connected to the wrist-padding 1 1. However, the wrist-strap 3 is provided with a curved design, where the curved design of the wrist-strap 3 will result in that the wrist-strap 3 will be positioned as shown in figure 2 when the right wrist-strap 3 is released from the corresponding left wrist-strap (not shown). The design of the wrist-strap 3 will therefore provide a solution where the base plate 2 of the binding 20 is held free. The snowboard river will therefore not have to remove the base plate 2 before the boot is placed into the binding 20 again.

Figures 3A-3E shows how the binding frame 1 of the binding 20 can be designed with attachment points 6 for the toe-strap 4 (see also figure 4A) or attachment points 7 for the wrist-strap 3 (see also figure 4A). The attachment points 6, 7 are then at least one through hole provided in the binding frame 1. The wrist-straps 3 and toe-straps 4 are then provided with one or more corresponding through holes. The binding frame 1 can then be provided with a single hole 6.1, 7.1 for both the wrist-straps 3 and toe-straps 4 as shown in figure 3A or double holes 6.2, 7.2 or triple holes 6.3, 7.3, as shown in figures 3B and 3C, respectively. The wrist-straps 3 and toe-straps 4 will then be guided into recesses R provided on each side of the binding frame 1 (see also figure 4A), where the recesses R extend a length down into the binding frame 1, and where the through holes 6, 7 are provided through the recesses R and the binding frame 1.

In figures 3D and 3E are shown embodiments of the binding 20, where the binding frame 1 is provided with double holes 7.2 for the wrist-straps 3 and triple holes 6.3 for the toe-straps 4 (figure 3D), while the embodiment shown in figure 3E is provided with triple holes 7.3 for the wrist-straps 3 and double holes 6.2 for the toe-straps 4. In addition to this, it can be seen that the double holes 6.2 for the toe-straps 4 in this embodiment are angled relative the binding frame 1.

On right sides of figures 3A-3C are shown, in cross-section, how a press- button element 5 (see also figure 5A or 7) is used to secure the wrist-straps 3 and toe-straps 4 to the binding frame 1, where the press-button element 5 then can comprise one pin (figure 3 A), two pins (figure 3B) or three pins (figure 3C).

Figure 4A is a perspective view of the binding 20 according to the present invention, where it can be seen how the wrist-strap 3 and toe-strap 4 are guided into the corresponding recess R, where a press-button element 5.3 with three pins is to be pushed into the triple holes 7.3 in order to secure the wrist-strap 3 to the binding frame 1, while a press-button element 6.2 with two pins is to be pushed into the double holes 6.2 in order to secure the toe- strap 4 to the binding frame 1. However, it is to be understood that also a press-button element 6.2 with two pins can be used to secure the wrist-strap 3 to the binding frame 1.

Figure 4B shows from above details of the binding frame 1, where it can be seen how the wrist-straps 3 can be secured to the binding frame 1. In this embodiment it is shown that the attachment point 7 is provided as double holes 7.2, where a press-button element 5 with a single pin is used to secure the wrist-straps 3 to the binding frame 1 . This arrangement will result in that the wrist-straps 3 can be adjusted to a greater extend, as the through hole in the wrist-straps 3 that is shown used to secure the wrist-straps 3 to the binding frame 1, can be moved to the foremost hole of the double holes 7.2, whereby the press-button element 5 with one pin can be used to secure the wrist-straps in this position. However, it should be understood that also a press-button element 5 with two pins can be used to secure the wrist-straps 3 instead of the press-button 5 with one pin.

Figure 5A shows the design of the press-button element 5, where the press- button element 5.1 for the sake of simplicity is provided with one pin. Left side of figure shows the press-button element 5.1 in a side view, while the right side shows the press-button 5.1 from above. The press-button element 5.1 is provided with a head section H, an intermediate section I and an outer section O. The head section H will then be in line with an inner side of the binding frame 1 when the press-button element 5 is pushed into the attachment point 6, 7, while the outer section O will be in line with an outer side of the binding frame 1 (see also figure 4A). The intermediate section I will then lock and secure the wrist-straps 3 and toe-straps 4 to the binding frame 1.

Figures 5B-5E show the press-button element 5.1 in different positions, where figure 5B show the press-button 5.1 before it is used to secure the wrist-straps 3 and toe-straps 4 to the binding frame 1, figure 5C shows the press-button element 5.1 after it has been pressed into the attachment points 6, 7, thereby securing the straps 3, 4 to the binding base, figure 5D shows the press-button element 5.1 in the same position as shown in figure 5C, where a highback 8 or base plate 2 is brought into a ready to use position, thereby covering at least a part of the press-button element 5, 1, preventing the press- button element 5.1 to "pop-out" unintentionally. Figure 5E shows how to press out the press-button element 5.1, first tilting the highback 8 away or removing the base plate 2. The press-button element 5.1 is pressed out of the binding frame 1 from the outside of the binding frame 1. A person skilled in the art would understand that the profiles of the press-button(s) 5 must be slightly larger than the corresponding attachment points (holes) 6, 7 provided in the binding frame 1 in order to assure that the pressure-button element 5 stay in position during riding with the snowboard.

Figure 6A shows in greater detail the design or profile 12 of the wrist-strap 3 according to figure 2. However, it should be understood that also the toe- strap 4 can be made with this design. The wrist-strap 3 (or toe-strap 4) is at one end provided with a through hole 14, where the press-button element 5 is guided through this hole 14 in order to secure the wrist-strap 3 or toe-strap 4 to the binding frame 1. At a distance from the hole 14, the wrist-strap 3 and/or toe-strap 4 is bent with a certain angle, where this bending will provide a solution where the base plate 2 of the binding 20 is held free,

In figure 6B the wrist-strap 3 (or toe-strap 4) is shown in a side view with marks for the different cross-sections, before, through and after the bend. The different cross-sections for the marks are shown in figure 6C, where it can be seen that cross-sections A and E will have the same design of the cross-sections, cross-sections B and D will have the same design of the cross- sections (the cross-sections have a certain curvature), while cross-section C will have a even more pronounced curvature. How the thickness, curvature, which material should be chosen etc. will depend on different parameters and a person skilled in the art would know how to solve this.

Figure 7 show a press-button element 5 according to figures 5A-5E, but with a different profile, where the press-button element 5 is shown in the different positions as explained in figure 5A-5E.

The present invention has now been explained by means of preferred embodiment. Only elements connected to the invention are described and a person skilled in the art will appreciate that the press-button element(s), attachment point and wrist-straps and toe-straps etc. are to be adapted to the specific use of the binding. The person skilled in the art will also understand that several changes and/or modifications may be made to the described and illustrated embodiments which are within the scope of invention as defined in the following claims.
