Abstract

The invention relates to a binding for a board, preferably a kiteboard, comprising a footrest, a foot loop, and at least one release device for opening the foot loop.

Description

The invention relates to a binding for a board, that is to say a piece of sports equipment in the form of a board, preferably a kiteboard, comprising a footrest, a foot loop, and at least one release device for opening the foot loop. The invention also relates to a board with a corresponding binding and a method for opening a binding.

Foot securing bindings and foot securing belts for sports boards, in particular safety bindings for sports board bindings, are known in principle.

So far, in water sports either no bindings, which is also known as "strapless", loop bindings, e.g. (foot) straps, or fixed bindings with boots, i.e. shoes, have been used.

Controlling the board without a binding is the most difficult. Control is much easier with a loop binding. With boots you have the greatest control over the board due to the strong fixation.

The most common type of binding used in kitesurfing are foot strap bindings. These are used from beginner training to professional classes.

In windsurfing, people often ride without a binding. In the advanced area, foot straps are used more often, although these have a less complex structure than in kitesurfing.

Boots are mostly used for wakeboarding, but foot straps are also used, especially for beginners. All of these types of attachment can cause injury.

Bindings with boots, which are known from snowboarding, for example, are sometimes used in kite and wakeboards.

The risk of injuries to the spine due to sudden braking of the body in the event of an unsuccessful jump prevents many users from riding with these bindings, e.g. when kiteboarding. The risk of drowning also increases with these bindings, as the legs can only be loosened by deliberately opening the boots. Strong injuries to the knee joint can also occur with tight bindings.

In contrast, in the case of loop bindings, a foot getting stuck in one of the foot straps is a major problem. This problem can occur during normal driving, during or after a jump or another maneuver.

One foot is released from the foot strap while the other remains stuck in the foot strap. The foot is also held in place by a torsion of the board, as the foot loop is twisted by the rotation and thus shortened.

There is a high risk for the user because the length of the kiteboard, which can be around 140 cm, acts as a lever on the lower extremities.

The injuries that occur range from stretching, sprains, knee injuries, torn ligaments, foot arch injuries to complex injuries to the ankle, dislocations and complex lower leg fractures and the like.

An injury resulting from the phenomenon of only one foot getting stuck is known as the onefooter injury.

In previous loop bindings, attempts have been made, on the one hand, to use the geometry of the foot pad, that is to say the footrest, and the foot loop to simplify the sliding out of the foot, for example by simply fixing it slightly.

The user drives the foot straps particularly loosely in order to prevent the foot from being fixed directly. However, this loses a more firm fixation to the board and thus better control over it.

On the other hand, the opposite approach is attempted, namely to design the geometry in such a way that the best possible fixation in the foot loop is made possible. The aim here is to prevent the user from being able to detach himself from the binding too easily in order to avoid injuries.

A higher degree of control is guaranteed in this way. If only one foot is released, however, it is significantly more difficult for the user to detach from the board and / or to shake off the board.

None of the approaches lead to a significant reduction in injuries. There have been no changes in medicine either. In the event of a fall and torsion of the board, large levers act on the respective fixed part of the body in both cases.

It is therefore an object of the invention to provide a binding, a board and a method for opening a binding, which in a simple manner reduces the risk of injuries.

This problem is solved by the subject matter and the method of the independent claims.

According to the invention, the binding is suitable for a board, preferably a kiteboard. In particular, the binding is suitable for a board that is used in water sports, for example also for a surfboard, wakeboard and / or foil board.

The invention also relates to a use of the binding for a board which is used in water sports and / or used barefoot, e.g. a kiteboard.

The binding includes a footrest and a foot strap. The foot loop can be fastened, in particular releasably, to the footrest, for example.

The footrest can preferably comprise an anti-slip and / or shock-absorbing material, for example rubber material. The foot loop can in particular comprise a textile material. The foot loop can preferably have a Velcro fastener. For example, the length of the foot strap can be adjusted.

A foot without shoes is preferably included in the binding. The foot is attached between the footrest and the foot strap. In particular, the footrest and / or the foot strap can be adapted to the shape of the foot.

The user is preferably barefoot in the binding. The term barefoot is to be understood broadly and also includes, for example, socks or light, elastic shoes, e.g. made of neoprene. However, it does not include sturdy shoes or boots. In particular, there is no fixed connection between the foot or a sock and the binding, as is the case, for example, with a ski or snowboard between a sturdy shoe, soft boot or boot and the binding. In contrast to ski or snowboard bindings, no shoes, soft boots or boots lock into the binding because the user stands barefoot on the board. According to the invention, the user, clothing and / or footwear of the user does not latch onto the binding or does not form part of the binding. On the user side, there is no fixed connection with the binding. A release by the user is therefore possible at any time.

The binding comprises in particular a fastening device for fastening the binding to the board. For example, the fastening device can comprise screws with which the binding can be screwed to the board.

Furthermore, the binding comprises at least one release device for opening the foot loop.

According to the invention, the foot loop is thus opened. A shoe, soft boot, boot or the entire binding, however, is not released or unlatched.

The release device has at least one side stop that can be actuated with one foot, in particular barefoot, for triggering the release device. The side stop can in particular be ergonomically shaped. The rotational forces can thus be safely and reliably transferred to the release device.

The triggering takes place preferably via the side surfaces of the foot. When the release device is triggered, the foot strap opens.

In particular, the foot strap opens without tools. An automatic release preferably takes place as soon as the load, the rotation of the foot and / or the torsion of the board exceeds a certain limit value.

It was surprising that a binding, especially a foot loop, can also be opened barefoot.

This is a simple way of reducing the risk of injury. In particular, onefooter injuries are reduced because the foot remaining on the board is released from the binding and thus from the board through the automatically opening foot loop.

Furthermore, even when driving barefoot, a secure hold and thus stable driving behavior is made possible.

Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

According to one embodiment, two release devices are provided which are assigned to different sides of the foot loop. The release devices are arranged in particular on both sides of the foot strap. The foot loop is evident on both sides.

Preferably, only one release device is always triggered. One side of the foot loop preferably remains on the binding, for example in the event of a fall. Alternatively, triggering both release devices is also conceivable. In this case, the foot strap is completely loosened. In particular, the foot strap can have a securing device, for example a cord, around which Not to lose ankle strap. The securing device can preferably be connected to the binding and / or the board.

Because two release devices are provided, the foot strap can be opened on both sides, depending on the load. Depending on the direction of rotation of the foot, the left or right side stop is activated. The corresponding release device is triggered, the foot strap opens and the foot is free.

According to a further embodiment, the side stop comprises a lever element or is connected to a lever element. The lever element can for example be arranged inside or outside the foot loop. The lever element is preferably freely rotatable and is not hindered by the foot strap. The lever element can, for example, be designed as a whole with the footrest so that it does not represent an extra component in particular.

The force exerted by the foot on the side stop is transmitted to the lever element. The lever element can in particular be pivoted. An end stop can preferably be provided in order to limit the rotary movement.

If the foot rotates, the side stop and thus also the lever are rotated.

The lever element is rotatably mounted on a rotating device. In particular, the rotating device forms a joint. The rotating device can preferably be designed as a cylindrical, preferably multifunctional, axle.

The lever element can be releasably attached, e.g., clamped, to the rotating device, e.g. by means of a screw. The position, in particular the angle, of the lever element in relation to the rotating device can be adjusted.

The release device can be triggered by the rotation.

Alternatively, a sensor, for example a pressure sensor, can also be provided, which measures a force acting on the side stop. If a limit value is exceeded, the release device can be triggered.

According to a further embodiment, the release device has a receiving area connected to the footrest and / or forming part of the footrest, on which the rotating device is arranged. The receiving area is designed in particular in the manner of a plate and / or comprises an at least essentially flat area. In particular, the foot loop and / or a release device connected to the foot loop can be received in the receiving area.

According to a further embodiment, the rotating device has a rotatable retaining lug.

The retaining lug can in particular be designed as a latching lug and / or form part of a latching mechanism. The retaining lug can in particular be pivoted via a release device or into a lateral recess of the release device and fix the release device in this way.

In particular, the rotating device has a retaining lug adjustment device for the retaining lug. The position of the retaining lug, in particular the angle, of the retaining lug can be adjusted via the retaining lug adjustment device, for example via a screw.

According to a further embodiment, the rotating device has a lever element setting device for the lever element.

In particular, the position, in particular the angle, of the lever element in relation to the rotating device can be adjusted via an angle adjustment device, for example a screw. For example, a fixing element, e.g. a screw, can be loosened. The lever element can now be rotated into the desired position and fixed using the fixing element. In this way the release angle can be adjusted. In this way it can be determined how much the lever element has to twist before the release device is triggered. The release angle can be set individually to suit the needs and / or physical characteristics of the user, e.g. body size and / or body weight.

According to a further embodiment, the rotating device has a counterforce and / or restoring device, in particular a spring device. The rotating device is biased in particular into a position in which the foot loop is closed. Unintentional opening can be prevented in this way.

The spring force, i.e. the preload, is preferably adjustable, e.g. via a spring adjustment device. The spring adjustment device can for example be arranged in the receiving area. In particular, the spring adjustment device can be arranged in the rotating device or outside the rotating device.

The resistance of the rotating device can be set in such a way that it prevents continued rotating too easily and / or prematurely and thus preventing the release device from being triggered. A Triggering occurs when the forces are held long enough with the necessary strength. The angle can be set individually to suit the needs and / or physical characteristics of the user, for example body size and / or body weight.

According to a further embodiment, a release device, in particular a release plate or release bar, is provided which is firmly connected to the foot loop and / or forms part of the foot loop and rests on the receiving area when the foot loop is closed.

The triggering device is preferably permanently connected to the foot loop. In particular, the release device comprises a rigid and / or solid material, e.g. plastic and / or metal.

According to a further embodiment, when the foot loop is closed, the release device is arranged at least in sections between the receiving area and the retaining lug of the rotating device. The triggering device is thus, to a certain extent, clamped.

An end region of the triggering device, in particular a front end region, can have a latching lug or a plurality of latching lugs. In particular, the end region can be forked.

The latching lug or lugs can latch or be plugged into a correspondingly shaped counterpart of the receiving area and form a tongue and groove connection. In this way, forces occurring in the Y direction can be stabilized. Snapping into place is also made easier for the user.

At least a section of the upper side of the release device can be designed as a flat side for the retaining lug. The retaining lug can thus be pivoted in a simple manner over the release device and fix the release device.

A centering device can be provided which restricts the freedom of movement of the release device. In particular, the receiving area can have a central centering bolt which can engage in a recess on the underside of the release device. Alternatively, the release device can have a centering pin and the release device a recess. The centering device can also have lateral stops, for example.

The centering device stabilizes the forces occurring in the X direction. This also serves in particular as a snap-in aid for a user. This also serves as an indicator of whether the release device is properly engaged.

The invention also relates to a board with a binding according to the invention. Two bindings according to the invention are preferably provided. So every foot can be held or released safely.

Finally, the invention also relates to a method for opening a binding, in particular a binding according to the invention, in which a side stop is actuated with one foot, in particular barefoot.

This triggers a release device, with a foot loop being opened by the release device.

The foot is thus free, which prevents injuries.
