Summary of the invention

The object of the invention is to propose a new fixing system of magnetic and / or electromagnetic type that allow a quick and secure fixation of the boot on the board. This purpose is achieved by a ski board, snowboard or similar to the type indicated at the beginning characterized by first fixing means comprise a magnetic surface variable and control means, where the control means are suitable for varying said magnetic surface according to some input parameters Such a table has the advantage combined that, on the one hand, the table may include a plurality of fixing zones while, on the other hand, it ensures that the user of the same will always fix the boot in the fixing area correct.

Indeed, normally, the fixations of Skis of mechanical type are fixed. They can be adjusted for different boot sizes but their position on the table is fixed, usually by screwing. The position thus defined it is an "optimal position", in the sense that it is the best position for "most cases". This position is determined on each table by professionals. If the boot is fixed in a different position, normally the result will be unsatisfactory, since the skier will not be able to properly dominate the skis. This can have multiple negative consequences: the skier not skiing satisfactorily, skiing benefits are wasted, increased fatigue of the skier, risk of injuries and even accidents, etc. However, in various cases it is interesting to have more than one position to set the boot, so, for example, in the case of tables snowboarding, conventional fixings usually have the possibility to position itself in at least two positions with respect to the axis longitudinal of the table. This is because, in certain cases, it is advantageous for each of the boots to form an angle different with the longitudinal axis of the table. Another example may be the case of advanced skiers for whom it can be interesting that the position of fixing the boot is shifted from that "optimal position for most cases" since the skier will ski in special or extreme conditions. For example, in the case of skiing through virgin snow it is interesting that the skier's body weight be in one more position delayed than in the normal case. Ski table bindings, snowboarding or similar described in the cited prior art previously they also have a single fixed position, except in the case of the solution proposed in PCT application WO 2005/092454, where the user can set the boot in any position. Without However, in the latter case there is a possibility that the boot be positioned in "not optimal" places, with the disadvantages already cited.

In the present invention, the table presents a variable magnetic surface and control means suitable for vary said magnetic surface according to parameters of entry. In this way, different areas of fixing and simultaneously, you can get the user to set the boot always in a correct position, since the means of control vary the magnetic surface so that only the Correct fixing area has a magnetic surface. For the therefore, the boot will be fixed exactly on the fixing area (and not outside of it) since the force of magnetic attraction is only will exercise there. If you try to put the boot totally or partially outside the fixing area, the force of magnetic attraction will be zero or much less than its nominal value (or, as will be discussed more forward, it can even be a force of repulsion), which will guide the skier so that he can quickly locate the correct position, corresponding to the desired fixing area. This is very useful for the ordinary use of skiing or snowboarding, and it becomes especially useful in the case of performing figures with the snowboard in which the user releases at will the electromagnetic fixing, make figures with the separate table of the feet and before landing the table is placed again with great comfort for the security that is achieved by having areas of greater Electromagnetic attraction to which the boots will be fixed.

The magnetic surface can be varied from various ways:

A way to vary the magnetic surface It could be mechanically. Thus, for example, the table could include a plurality of pieces of soft ferromagnetic material (it is say, they don't retain the magnetic field for a while significant, such as iron or steels with low carbon content (sweet steels)) that were fixed to the table with the possibility of being displaced or disassembled. For get the magnetic surface to be in fixing areas different would be enough to move the piece (or pieces) of soft ferromagnetic material to the right places or with mounting and disassemble the pieces properly so that only remain pieces in the fixing area of interest. In both cases, what is is doing is vary the physical geometry of the surface magnetic based on adding, removing or moving the pieces of soft ferromagnetic material that, in short, they define, so less partially, the magnetic surface. Logically you are pieces of soft ferromagnetic material can coexist with electromagnets or permanent magnets that, for example, may be arranged in common places to all fixing areas.

However, a preferred solution is obtained by providing the first fixing means with a plurality of electromagnets that define the magnetic surface and that are suitable to be activated or deactivated by the control means, of the so that at least one of the electromagnets is apt to be enabled or disabled regardless of the remaining electromagnets, thus varying the magnetic surface. Effectively, in this way a variable magnetic surface can be achieved by means of electronic control means, for example a microprocessor that, together with a power supply, is suitable to activate and deactivate certain electromagnets depending on of control parameters that are provided. In this case, the magnetic surface is not modified by modifying it geometrically but what is modified is the magnetic field of the same. This way it is not necessary to do the operations laborious to assemble, disassemble or physically move ones pieces.

Electromagnets can be used for various forms For example, they can be used to generate a field capable of attracting the second fixing means Ferromagnetic present in the boot. Thus, the first means of table setting may comprise a plurality of electromagnets and control means can only activate those electromagnets that correspond to the fixing zone that, at any given time, the user wishes to use.

Alternatively, electromagnets may be overlapping with permanent magnets. In this case, the first media of fixing the table can comprise a plurality of magnets permanent of which at least one part has overlapping some electromagnets that are apt to generate a field electromagnetic opposite to the corresponding permanent magnet, canceling it In this way, the control means can activate the electromagnets that are necessary so that they only remain without cancel the permanent magnets corresponding to the fixing area that you want to use at any given time. In this alternative, the Electromagnets can be disconnected once the boot has been fixed, since then it is no longer necessary to cancel the magnets permanent of the other fixing areas.

The second means of fixing the boot They can be both permanent magnets, electromagnets, pieces of soft ferromagnetic material and combinations of the above and they can also have a few second means of control that govern The electromagnets

Electromagnets also have the advantage of that the polarity of its magnetic field can be reversed based on reverse the direction of the electric current that generates it. It can be used to get some electromagnets certain of the table have a magnetic field that attracts second fixing means present in the boot (assuming that be electromagnets or permanent magnets) while others electromagnets can have a magnetic field that repels the boot.

Logically, the above alternatives are combinable with each other and, in fact, they are also combinable with mechanical adjustment alternatives discussed above.

Control parameters can be communicated to the means of control in various ways. Control means they can have some means of input to which they can be connected an external device (for example, via a USB connection or similar, which can also serve as a power connection for the power supply, which is preferably a battery. Alternatively the control means may have means of telecommunication, or they may even have sensors on their own table (for example, the user can position the boot in one place approximate to the desired position, the control means may have sensors that detect it and activate electromagnets corresponding. The control means can be more or less sophisticated. Thus, in the event that it is only foreseen that the table has two fixing zones, then the control means They can be simple. However, the invention is particularly advantageous in the case of tables for advanced users, in which it is interesting to have a plurality of control zones, eventually little separated from each other but that allow to obtain in each case the maximum performance of the table and knowledge of the user. In this case it is convenient that the first means of table setting comprise a high amount of electromagnets, each of them of small dimensions, so that you can have a variable magnetic surface in a way almost continuous, so you can have fixing areas a few centimeters apart. In this case, the means of control can take into account a plurality of parameters, such as skier parameters (age, weight, number and type of boot, sex, level of knowledge, etc.) of snow (hard, dust, virgin, etc.), etc.

It should be noted that the source of food does not necessarily have to be physically integrated into the table but may be located elsewhere. For example, it can be carried by the skier (in boots or in any other place of your equipment) and you can transfer the electric power to the table, for example, through a connection electric It is also possible that the control means understand Two power supplies: one for media electronics control (which have a very low consumption and may be housed in the table itself), and another to feed the electromagnets, which can be independent of the table.

With the solution proposed by the invention, get the result that the user has the indication precise areas of optimal positioning of the boots according to different alternatives, such as snow quality or style that you want to practice. The control means vary the magnetic surface and ensure that the boot is fixed on said optimal position that will logically correspond to one of the predefined fixing areas.

Having the optimal positions clearly delimited also has the advantage that the boot can be fixed on the table very quickly, since there is no risk of fix the boot in an incorrect position, slightly offset from The optimal position.

The fixing areas may be totally separated from each other. However, in various cases it is advantageous that at least two of the fixing areas are partially overlapping each other. Indeed, on the one hand it is advantageous that the fixing areas are relatively large and that it will be, easier to have more attractive magnetic forces powerful. Thus, the fixing areas can become practically like a boot print. On the other hand it is frequent that the required position changes are not so great. Overlapping the fixing areas, the possibility of have large fixing areas with the possibility that each zone of fixation have its optimal position, regardless of remaining fixing areas.

Preferably, the table comprises stops which delimit, at least partially, fixing areas. The stops may be, for example, small stems or protrusions. that optically indicate where the fixing area is and that, preferably, they allow some guidance from the boot to the position correct. These stops may already be installed by the manufacturer of the table or can be installed at the point of sale, which has the added advantage that can be installed with the boot in mind concrete that the skier will use, so they can be installed with greater accuracy

Alternatively, the table includes some marks which delimit, at least partially, fixing areas. These marks may be printed on the table, so that the skier see where you have to "step on" to put the boot on the correct position. As in the previous case, these brands They can come from the factory or they can be done later.

Another possible alternative is that the table has some luminous elements that delimit, at least partially, fixing areas These luminous elements can be, by For example, LEDs that indicate the position of the toe and / or the heel, and may also be controlled by the means of control, so that in each case the control means can activate the luminous elements corresponding to the zone of active fixation. They can also, for example, be on only when detection means inform the media of check that the boot is not fixed in the fixing area correspondent.

These three ways to delimit the areas of fixation are not incompatible with each other, on the contrary, it can be particularly interesting to combine them so that their advantages accumulate.

The subject of the invention is also a support of ski, snowboard or similar boards, where the boards are of according to the invention, characterized in that it comprises a electrical connection suitable for supplying electrical energy to said boards.

The object of the invention is also a fixing system of a boot on a ski board, snowboard or similar, characterized in that the table is in accordance with the invention and the boot comprises at least one permanent magnet, a electromagnet and / or a soft ferromagnetic material.

Detailed description of some embodiments of the invention

Figs. 1 and 2 show some basic forms of embodiment of the invention. In each case table 1 has a plurality of fixing zones 3. When the user wishes to use the Table 1, you must decide which fixing zones 3 you want to use. For this, the areas to be used must be activated, which can be performed in various ways:

- mechanically: adding material soft ferromagnetic, a permanent magnet and / or an electromagnet in the fixing zone 3 to be used or by removing these elements from the fixing zone 3 to discard.

- electronically: activating electromagnets in the fixing zone 3 to be used, and / or activating electromagnets in the fixing areas 3 to be discarded to cancel out magnets permanent willing in these areas.

In this way, the magnetic surface 5 variable acquires a specific form. For example, the one marked as 5 'in Fig. 1, that is, the left foot must go to the area of 3 inclined fixation while the right foot should go to the area of fixation 3 perpendicular to table 1.

As you can see, there may be some positions that are common with all fixing zones 3. In these positions there may be a permanent magnet (no need for any electromagnet that is capable of canceling it) and / or there may be a material soft ferromagnetic (corresponding to a magnet or electromagnet of the boot).

An example is shown in Fig. 3 in which the variable magnetic surface 5 is formed by a plurality of electromagnets (or permanent magnets each with a electromagnet capable of canceling its magnetic field, or a combination of both). In this case, it is observed as the fixing zone 3 it can be adjusted with great precision, not only in the sense of longitudinal axis, from table 1 but also transversely and / or with any degree of inclination.

In Figs. 4 and 5 show some cases in the that tables 1 like those in Figs. 1 and 2 have a surface magnetic variable 5 as in Fig. 3.

Finally, a table 1 is shown in Fig. 6 equivalent to that of Fig. 4 but in which the magnetic surface size 5 variable, with the consequent Cost and weight savings.
