Provided is a locking mechanism for a ski-binding, the locking mechanism comprising only one lever adapted to be pivoted between an engaged and a disengaged position. The lever further comprises at least one lug, the at least one lug adapted to engage with a notch formed in a mounting plate in an engaged position, and wherein the lug is adapted to hold the lever in a non-sliding manner when engaged with the notch. Explicitly, the locking mechanism does not comprise a second lever. Also provided is a ski-binding comprising only one locking mechanism, or adapted to receiving only one locking mechanism, and a mounting plate for use with the locking mechanism, and ski-binding.
This application is a continuation of U.S. application Ser. No. 15/126,872, filed on Sep. 16, 2016, which is a Section 371 National Stage Application of International Application No. PCT/EP2015/055814, filed 19 Mar. 2015 and published as WO 2015/140258 A1 on 24 Sep. 2015, in English, the contents of which are hereby incorporated by reference in their entirety.
DESCRIPTIONThe present invention relates to a locking mechanism for use with a ski-binding, in addition to a ski-binding including or adapted to receive the locking mechanism. Further, the present invention provides a mounting plate suitable for engaging with the locking mechanism of the present invention.
Ski-bindings are generally used to attach a ski boot in a secure and safe manner to a ski. In the general art, a mounting plate is provided on the top surface of the ski and a ski binding is subsequently positioned relative to the mounting plate and attached at a desired position. Once attached, the ski-binding is locked onto the plate.
Conventional skis often employ a ski-binding in a relatively fixed orientation to the ski and mounting plate. To adjust the location of the binding, one must often use a special tool to loosen the locking mechanism and slide the binding to the desired position, before fixing the binding using the same tool. For conventional skis, the position of the ski-binding is often not required to be changed, particularly for skiers of a beginner or amateur ability.
However, for advanced skiers, and more specifically, for cross country skiers/skis, the position of the binding relative to the ski is of crucial importance. Indeed, different snow conditions can require different positions of the ski-binding for the skier to be able to obtain maximum performance from the ski.
Snow conditions can be affected by all manner of environmental conditions. For example, the snow condition can change with differing temperatures, the age of the snow, the relative atmospheric pressure, the current weather condition, and many other factors.
For a skier to obtain the maximum performance from the ski, the weight distribution of the skier must be optimal. Moreover, the skier also develops a certain “feel” of the snow through the ski. To achieved the best “feel” and inherently increase the skiers confidence, the position of the ski-binding must be changed depending upon the conditions.
In cross-country skiing in particular, the snow conditions can vary over the length of the run or course. In some cases, the snow conditions can vary substantially, meaning that it is beneficial for the skier to stop and adjust the position of the ski-binding despite losing time by doing so. In other words, the skier may travel faster and/or with more control by adjusting the position of the ski-binding mid-run.
Of course, stopping to adjust the ski-binding means that the skier loses time and it is desirable to minimise the time that the skier spends adjusting the position of the ski-binding.
EP 1 748 827 B1 discloses a system for adjusting and locking the position of a ski-binding relative to a mounting plate. In this document, a latching device includes two, oppositely facing latch units that are adapted to interact with notches provided on the mounting plate. Each latch unit is provided with locking teeth that have a certain profile, typically one that is similar or matches the profile of the notches.
The notches and locking teeth are arranged in an oppositely facing manner. In this sense, the profile of the locking teeth and notches is approximately in the shape of a right angled triangle. The forward or front latch unit is provided with the teeth orientated such that the right angle of the right angled triangle faces a first direction, typically the forward direction, and the rearward or rear latch unit is provided with the teeth orientated such that the right angle of the right angled triangle faces a second direction, typically the rearward direction. Accordingly, the notches are provided with the corresponding profile.
In operation, a skier may actuate the front or rear latch unit from a locked position, which is an at rest position, to an unlocked position by applying an upward force to an edge of the latch unit. Accordingly, once one of the latch units is unlocked, the binding may slide in a certain direction—when the front latch is actuated, the binding may be slid towards the front of the ski and vice versa with the rear latch unit.
To lock the ski-binding in place, the latch units are released by the skier and are elastically forced into the notches. To prevent forward and backward movement, the oppositely facing latch units apply oppositely directed resistive forces due to the orientation of the locking teeth and the notches. In other words, the presence of two latch units prevents forward and backward movement of the ski-binding when the locking teeth thereof are engaged with the notches.
However, a skier must operate one or the other of the latch units to achieve the desired orientation. For example, suppose a skier wishes to move the ski-binding forward, and actuates the front latch unit accordingly. Then, suppose the skier moves the ski-binding too far forward. The skier must then either release the front latch unit first and then actuate the rear latch unit, or actuate the rear latch unit at the same time as the front latch unit.
If the latter is performed, this means that both hands of the skier are used to actuate the latch units. While the ski-binding is provided in a sliding engagement, the ski-binding may nevertheless provide some resistive force to being slid, thus meaning an additional force is required to slide the ski-binding from one position to the other. In either case, the time required to correctly and accurately align the ski-binding can be lengthy.
Moreover, the locking teeth of the prior art are held in place only via the resistive force of the latch unit. In some cases, considerable force may be applied to the latch unit, for example, during falling. This may cause the ski-binding to inadvertently change position. A fine balance is required when determining the resistive force; too weak and the latch unit will inadvertently actuate, too strong and the skier requires additional means to actuate the latch unit.
A need exists, therefore, for a locking mechanism that enables precise and accurate positioning and locking of a ski-binding, and requires minimal input or action from the skier. Moreover, the locking mechanism should be quick to operate and, preferably, not require the use of any tools.
SUMMARYThe problem is solved by a locking mechanism for a ski-binding, the locking mechanism comprising:
-
- only one lever adapted to be pivoted between an engaged and a disengaged position,
- wherein the lever comprises at least one lug, the at least one lug adapted to engage with a notch formed in a mounting plate in the engaged position,
- wherein the lug is adapted to hold the lever in a non-sliding manner when engaged with the notch, and
- wherein the locking mechanism does not comprise a second lever.
A ski-binding is provided with a locking mechanism adapted to lock the ski-binding in a desired position with respect to a mounting plate. In this regard, the ski-binding is able to slide in a longitudinal direction of the mounting plate. The mounting plate is generally located on a top surface of a ski and includes one or more notches. The notches may take any shape but are preferably the same shape with respect to one another.
The locking mechanism includes only one lever and explicitly does not include a second (or further) lever. The lever is provided with at least one lug located, preferably, on an underside surface of the lever, wherein the lug is adapted to engage one of the notches provided in the mounting plate. The lever is able to be pivoted from a disengaged position, where the lug is not engaged or in contact with the notch, to an engaged position, where the lug is engaged or in contact with the notch. The pivoting of the lever may be realised by attaching the lever at one end to the ski-binding or, preferably, providing the lever and ski-binding as an integral component such that the lever protrudes from the ski-binding. Preferably, the lever is able to be pivoted without the use of any tools or the like, thus meaning that the skier does not have to carry additional weight or equipment with them.
The lug may engage the notch in any number of ways. Preferably, the lug engages the notch in a press fit manner, such that the lug requires some force to be exerted to insert the lug into the notch. In a preferred arrangement, the lever is biased to a disengaged position such that, when movement of the lever is enabled (e.g., by disengaging locking means), the bias of the lever causes the lug to disengage or be removed from the notch. In other cases, some force is required to remove the lug from the notch. In this way, the lever and thus the ski-binding is provided in a non-sliding manner with respect to the mounting plate and ski when the lever is in the engaged position.
Providing only one lever and locking mechanism is advantageous in that a skier who wishes to adjust the position of the ski-binding is provided with only a single component to operate in order to adjust the ski-binding to any desired position, be it forwards or backwards of the current position. Providing only one lever means that a skier is able to spend minimal time actuating the locking mechanism to both disengage and engage the locking mechanism when altering the position of the ski-binding. This decreases the time that a skier spends stationary and also increases the opportunities that a skier may stop and adjust the ski-binding.
In one embodiment, the lug comprises a front-facing surface having a contour similar to a front surface of the notch, and a rear-facing surface having a contour similar to a rear surface of the notch, wherein, when the lug is engaged with the notch, the front-facing surface and the rear-facing surface are adapted to contact the front surface and the rear surface of the notch.
Providing the contours or profiles of the lug and notch in a similar fashion enables the lug to be press fitted into the notch and ensure a rigid engagement of the lug. This means that the lug (and thus the ski-binding) does not move forwards or backwards even when in the engaged position. In some arrangements, the rigid engagement may enable the lug to be held in place via the frictional or compressive forces provided by pushing or compressing the lug into the notch. This provides more resistivity when a single lever is used such that the skier may not inadvertently move the ski-binding when, for example, having adjusted the ski-binding before fixing or tightening the ski-binding. It is also possible that only a part of the front-facing surface and rear-facing surface of the lug match or contact the front and rear surfaces of the notch.
A further embodiment comprises locking means, the locking means adapted to lock the lever in the engaged position when the lever is engaged with the notch.
Providing locking means enables the lever to be locked in the engaged position and thus remove the possibility of the lever being actuated inadvertently, i.e., during skiing. Preferably, the locking means is also actuated without the use of additional tools, such that the skier may simply stop during a run, unlock the locking means, and adjust the position of the ski-binding without the use of tools. The locking means can include any form of means that enables the lever to be locked in the engaged position. Equally, an alternative locking means may be provided that retains the lever in the disengaged position during adjusting the position of the ski-binding.
In one embodiment, the locking means may comprise at least one of a recess and a protrusion, wherein one of the recess or the protrusion is provided at a distal end of the lever and is adapted to engage a recess or protrusion located on the ski-binding when the lever is in the engaged position.
In addition, or alternatively, the locking means preferably comprises a sliding plate, the sliding plate adapted to slide so as to lock the lever in the engaged position when a part of a surface of the sliding plate is positioned over a part of a top surface of the lever.
In a preferred embodiment of the locking means including a sliding plate, the lever is biased to the disengaged position, and the lever is adapted to move against the biasing force into the engaged position when the sliding plate moves from an unlocked position to a locked position.
In a preferred configuration of the sliding plate, the lever is provided so as to be biased in the disengaged position. That is, at least a part of the lever may be provided biased away from the notches of the mounting plate or the horizontal plane of the ski-binding. In such an arrangement, an upper surface of the lever may be provided at an angle with respect to the horizontal plane of the ski-binding. The sliding plate may be provided in an unlocked position that allows the lever to pivot. This unlocked position may be realised by providing the sliding plate such that it does not engage or come into contact with the lever. In the unlocked position, the lever (and thus the ski-binding) is able to be slid along the mounting plate until a desired position is reached where the lug may engage with a corresponding notch of the mounting plate. To lock the lever, the sliding plate may be slid towards the biased lever such that the sliding plate engages a surface (preferably the inclined surface) of the lever. A continued sliding of the sliding plate causes the biased portion of the lever to move in a direction towards the notches of the mounting plate. In other words, a user actuating the sliding plate acts against the biasing force of the lever biased in the disengaged portion to thereby cause the lever to move to the engaged position. The sliding plate may then subsequently be locked by additional means or may simply prevent the lever from moving to the biased disengaged position given the relative frictional forces involved.
Moreover, the lever may additionally or alternatively, comprise at least one of one or more side protrusions and one or more side recesses, the side protrusions or side recesses provided on a side of the lever between the distal end and a proximal end of the lever, the side protrusions and side recesses adapted to engage corresponding protrusions and recesses located in the ski-binding.
The above mentioned locking means enable the lever to be held in the engaged position as discussed above. Each of the locking means has the advantage that the skier may actuate the means by hand, and thus avoids the need for specialised tools. Moreover, any combination of the above locking means may be utilised, i.e., a lever comprising side protrusions, and a sliding plate, for example. While specific embodiments have been detailed above, the invention is not limited to locking means of this nature. Any locking means may be utilised, provided that the locking means is adapted to lock the lever in the engaged position.
In one further embodiment, the lever is adapted to be pivotingly engaged with the ski-binding at a proximal end of the lever, and wherein the lug is positioned between the distal end and the proximal end of the lever.
A pivoting arrangement of the lever provides only one possible direction, and thus one possible direction of force, that the skier must actuate the lever in order to adjust the ski-binding. This is much more intuitive than, for example, a rotary motion of a dial or the like—unless the skier is familiar with the dial, the skier may not be aware of which way to adjust the dial for the desired position of the ski-binding. Providing the lever negates this unfamiliarity with the ski-binding. In addition, the pivoting nature of the lever reduces the number of moving components required, not only for actuation of the locking mechanism, but also for adjustment of the ski-binding.
In some cases, the lever is provided as an integral component with the ski-binding, and is pivoted at a portion between the lever body and the ski-binding.
Such a portion may have a weakened region, for example, a region of a decreased thickness or a region made from a more flexible material, so as to allow for the pivoting of the lever.
Alternatively, the proximal end of the lever may comprise one or more hook portions, the one or more hook portions adapted to engage a corresponding attachment portion located on the ski-binding, wherein the hook portions enable pivoting of the lever when attached to the attachment portion of the ski-binding.
Preferably, the one or more hook portions are provided in an alternating arrangement along the proximal end of the lever such that, when viewed along the pivoting axis of the lever, the hook portions form a C-shape or a circular shape, and wherein the one or more hook portions are adapted to be flexible such that the hook portions deform from the pivoting axis when engaging with the attachment portion.
The use of hook portions located on the lever allow for easy attachment and replacement of the lever from the ski-binding, while also allowing for rotational movement around an axis coinciding with the axis of the hook portions. Furthermore, providing the hook portions in an alternating arrangement enables a precise method for removing the lever, thus meaning that the lever is unlikely to be inadvertently removed.
In a further embodiment, the proximal end of the lever is integrally formed with either a mounting block adapted to be fixed to the ski-binding or the ski-binding itself, wherein the proximal end of the lever is adapted to have an increased flexibility compared to the lever and mounting block or ski-binding, thereby allowing pivoting movement of the lever at the proximal end.
In a further embodiment, the front-facing surface of the lug is provided at an angle with respect to the rear-facing surface, wherein, when the lever is actuated from the disengaged position to the engaged position, the front-facing surface is adapted to engage with the front surface of the notch and provide a forward directional force to the lever thereby moving the lever in a rearward direction to align the lug with the notch.
Providing an angled portion of the front side of the lug means that, should the skier move the binding too far forward or backward, the interaction of the angled surface with the notch forces the lever and thus the ski-binding to the appropriate location on the mounting plate, i.e., such that the lug is aligned with the notch. This means that the skier does not have to precisely align the ski-binding with the notches but may align the ski-binding within a certain tolerance.
In a further embodiment, the lug is adapted to be engaged with the notch in a water-tight manner when in the engaged position. Preferably this is realised by sizing the profiles of the notch and lug to be similar. Providing a water-tight engagement between the notch and the lug ensures that snow and/or dirt cannot enter between the surfaces of the notch and lug. In the case of snow, the snow can freeze when trapped between the lug and notch, thus meaning that a skier must apply larger forces to the lever in order to remove the lever from the engaged position.
In one embodiment, the rear-facing surface of the lug comprises one or more grooves, the grooves adapted to provide a weakening in the rear-facing surface of the lug such that the lug is adapted to be compressed and/or flexed around the axis of the grooves. Providing these grooves enables the lug to be flexed when a skier presses the lug into the notch, thereby aiding the insertion of the lug and reducing the force required to compress the lug.
In another embodiment, the lever may be provided with an indent portion sized and shaped to receive at least a fingertip of an operator of the lever, thereby enabling the operator to grasp the lever when in the engaged position and actuate the lever to the disengaged position. The indent portion is not particularly limited in design or shape.
The problem is also solved by a ski-binding adapted to receive only one locking mechanism according to any of those discussed above, wherein the ski-binding is adapted to be slidingly engaged with the mounting plate and, when the lug is engaged with the notch in the locked position, is adapted to be held in a non-sliding manner, wherein the ski-binding is not adapted to receive a second locking mechanism.
The problem is also solved by a ski-binding comprising only one locking mechanism according to any of those discussed above, wherein the ski-binding is adapted to be slidingly engaged with the mounting plate and, when the lug is engaged with the notch in the locked position, is adapted to be held in a non-sliding manner, wherein the ski-binding does not comprise a second locking mechanism.
In one embodiment of the ski-binding, when the lever is in the disengaged portion, the ski-binding is adapted to slide in a forward and rearward direction with respect to the mounting plate.
In a preferred embodiment, the ski-binding further comprises a lever-receiving hole adapted to receive the lever, and wherein the lever-receiving hole is adapted to pivotingly provide the lever at one end of the lever-receiving hole.
Preferably, the lever-receiving hole is provided in a top surface of the ski-binding such that a top surface of the lever, when the lever is in the engaged position, is provided flush with the top surface of the ski-binding. In this way, an edge of the lever does not protrude from the surface of the ski-binding, meaning that the lever cannot be caught on obstacles or by the skier's boot and actuated unintentionally. In a preferred arrangement, the lever-receiving hole is located at a position under the skier's boot, when the skier's boot is engaged with the ski-binding.
The lever may also be provided as an integral part of the ski-binding, the lever provided at an end of the lever-receiving hole and adapted to pivot at that end.
In one embodiment, the ski-binding further includes at least one of:
-
- one or more recesses and/or one or more protrusions located at an end of the lever-receiving hole opposite to where the lever-receiving hole is adapted to pivotingly provide the lever, wherein the one or more recesses and one or more protrusions are adapted to receive corresponding recesses or protrusions located on the lever;
- sliding plate accommodating means that is adapted to accommodate a part of a sliding plate when the lever is in the engaged position, or accommodate the entire sliding plate when the lever is in the disengaged position;
- one or more side protrusions and one or more side recesses located at a side portion of the lever-receiving hole and adapted to receive side protrusions and side recesses of the lever; and
- an edge portion adapted to receive side clips provided on the lever.
Depending upon the explicit configuration of the lever, and more particularly, the locking means of the lever, the ski-binding and the lever-receiving hole may comprise reciprocal components adapted to interact with the locking means of the lever.
The present invention also provides a mounting plate for use with the locking mechanism described above or the ski-binding described above, wherein the mounting plate comprises only one set of notches, and wherein the set of notches comprises notches having the same shaped profile and orientated in the same direction.
The present invention also provides a system including only one locking mechanism, the ski-binding, and the mounting plate described above, wherein the ski-binding is adapted to slidingly engage with the mounting plate and the only one lever of the locking mechanism is adapted to engage with one of the one set of notches of the mounting plate, thereby preventing sliding movement of the ski-binding.
These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
In the following drawings:
According to the present invention, the ski-binding 2 is provided with a single locking mechanism 6 that is adapted to hold and/or lock the ski-binding in a desired position. As shown in
As shown in more detail in
The mounting plate 2 includes a plurality of notches 12 spaced apart from each other in a longitudinal direction of the mounting plate 2 as shown in the Figures.
In essence, the lug 10 may be engaged with any one of the notches 12, and it should be appreciated that, in order to engage the lug 10 with a different notch 12, the ski-binding 2 is slid in a longitudinal direction (i.e., forwards or backwards) so as to align the lug 10 with the desired notch 12.
In the disengaged position, as shown in
In the engaged position, as shown in
The lever 8 may be biased to a certain position. In a preferred arrangement, the lever 8 is biased into a disengaged position, i.e., the position as seen in
Preferably, the ski-binding 2 includes a lever-receiving hole 3 that is adapted to receive the lever 8 when the lever 8 is in the engaged position. In one arrangement, a top surface of the lever 8 is provided flush with a top surface of the ski-binding 2 when the lever 8 is in the engaged position. This is advantageous because the edges of the lever 8 are not exposed in such an arrangement and are thus not prone to being caught or knocked by various obstacles or by the ski-boot of the skier.
It should be noted that, although only one lug 10 is shown in
According to the present invention, only one locking mechanism 6 and thus only one lever 8 is provided to the ski-binding 2. That is, the present invention explicitly does not include a second or more locking mechanisms 6 or levers 8. This is a fundamental concept of the present invention, as the provision of only a single locking mechanism 6 enables a skier to more quickly and efficiently alter the position of the ski-binding 2 on the mounting plate 4, thereby reducing the time spent adjusting the ski-binding 2. Herein, a skier is given as the person that alters the ski-binding 2 for ease of reading, however, any person, such as a technician or the like, may equally alter the position of the ski-binding 2.
It should also be noted that the lever 8 may face either direction on the ski-binding 2. That is, for example, the pivot point of the lever 8 may be positioned forward of the movable end of the lever 8 in relation to the ski-binding 2, in which case the lever 8 may be said to be rearward facing. Conversely, the pivot point of the lever 8 may be positioned behind the moveable end of the lever 8 in relation to the ski-binding 2, in which case the lever 8 may be said to be forward facing. Whether the lever 8 is forward or rearward facing may depend upon the intended use of the ski-binding, i.e., the type of skiing or certain techniques. For example, a rearward facing lever 8 may be preferential for resisting certain forces when used during skiing, i.e., the counterforce of the skier when moving the ski backwards. Although the Figures herein may show the lever 8 in one or the other direction, it should be appreciated that any of the directions may be used and the position of the lever 8 is not limited in this regard.
The notch 12 may also include a front surface 18 and a rear surface 20. In a preferred embodiment, the front-facing surface 14 and the front surface 18, in addition to the rear-facing surface 16 and the rear surface 20, are in contact with each other when the lug 10 is pressed into the notch 12. In one embodiment, the lug 10 may be made from a compressible material and may be formed so as to have a profile that is larger than the profile of the notch 12. In this arrangement, the lug 10 exerts a compressive force on the surfaces 18, 20 of the notch 12 which may prevent movement or disengagement of the lug 10 from the notch 12.
Preferably, the profiles of the lug 10 and notch 12 are similar, although this does not need to be the case. In this regard, only a part of the front-facing surface 14 and the rear-facing surface 16 may be in contact with the front and rear surfaces 18, 20 of the notch 12.
In one further arrangement, the front-facing surface 14 and the front surface 18 may be provided at an angle with respect to the rear-facing surface 16 and the rear surface 20 as shown in
In some further embodiments, the lug 10 may also be provided with one or more grooves 22 provided along the rear-facing surface 16. Preferably, the grooves 22 are orientated along the width direction of the lug 10 and are essentially formed around an axis. In this regard, the grooves 22 may act as weakened portions of the lug 10 and permit relatively more compression and/or flexion of the lug 10 around the axis of the grooves 22. Such a configuration can aid in the insertion of the lug 10 into the notch 12 and reduce the force required by the skier to perform such, while also maintaining the tight fit with the surfaces 18, 20 of the notch 12.
In a preferred configuration, the interaction of the lug 10 and the notch 12 is provided in a water-tight manner such that snow or the like cannot be disposed between the surfaces of the lug 10 and notch 12 when in an engaged position. In some cases, depending upon the temperature, snow that enters the spaces between surfaces of the lug 10 and notch 12 may freeze therebetween, meaning that the lug 10 becomes much harder to remove from the notch 12. Preventing this is advantageous and means that the skier is always able to remove the lug 10 from the notch 12. Preferably, this is enabled by forming the surfaces of the lug 10 and the surfaces of the notch 12 in such a manner that they contact each other in the engaged position.
Generally speaking, the lever 8 may include a distal end 24 and a proximal end 26. The proximal end 26 is provided as the pivoting end of the lever 8 meaning that the motion of the lever 8 between the engaged and disengaged positions is effectuated at this end. Accordingly, the proximal end 26 also has a pivoting axis which is orientated along a width direction of the lever 8.
In the example of
The hook portions 28 may be provided in an alternating fashion along the pivoting axis or proximal end 26 so as to enable a clamping effect with the attachment portion 30. To this end, when viewed along the pivoting axis, the hook portions 28 form a C-shape or a circular shape. In a preferred arrangement, the gap between the ends of the C-shape is less than twice the radius of curvature of the hook portions 28. In this regard, the hook portions 28 may be flexible such that, when pushed towards the attachment portion 30, the hook portions deform away from the pivoting axis to allow the attachment portion 30 to be located along the pivoting axis. Such an arrangement enables the lever 8 to be stably and pivotably attached to the attachment portion 30.
In some further configurations, the hook portions 28 are provided only in an up or down configuration. Accordingly, the attachment portion 30 of the ski-binding 2 may be provided with inserts that are arranged in such a manner to enable a precise locating and fitting of the lever 8. To remove the lever 8, one must also remove the lever 8 in a precise manner according to the location and/or orientation of the inserts, thus meaning that an inadvertent removal of the lever 8 is not possible.
The lever 8 may also be provided with an indent portion 32. The indent portion 32 is preferably sized and shaped to receive at least a fingertip of the skier. In this way, the skier is provided with a better grip or leverage in order to remove the lever 8 from the engaged position. Further examples of the indent portion 32 and removal means are described later.
The locking mechanism 6 may also be provided with locking means 34. The locking means 34 may be any type of locking means 34 that enables the lever 8 to be locked in the engaged position in such a manner that the lever 8 is not easily displaced from the engaged position. In one arrangement, the locking means 34 may be equivalent to the lug 10 and notch 12 interaction as discussed with respect to
The locking means 34 of this example is realised by at least one recess 36 and at least one protrusion 38. In
In this regard, either the distal end 24 of the lever 8 or the protrusion 38 may be provided with some flexibility which enables deformation of the recess 36 or protrusion 38 when the lever is pressed into the engaged position. However, the level of flexibility must not be too great so as to allow the lever 8 to inadvertently move to the disengaged position. Therefore, the skier must apply an additional force to the lever 8 when positioning the lever 8 in the engaged position in order to overcome the resistive forces provided by the flexible recess 36 or protrusion 38. In one arrangement, the ski-binding 2 is provided with a gap 40 that accommodates the flexion of the protrusion 38 and/or the element of the ski-binding 2 that the protrusion 38 is provided on.
Although the recess 36 is provided on the lever 8 and the protrusion 38 is provided on the ski-binding 2 in
This arrangement is preferable when the lever 8 is arranged as a single piece component with the ski-binding 2. As shown in
In essence, the configuration of the protrusions 38 and recesses 36 is not particularly limited. The shapes of either of these components are not limited to those described above, and may take any shape that allows for the locking nature of these components. Equally, the distal end 24 and the surface of the lever-receiving portion 3 opposite to the pivoting axis are not limited in their shape. For example, the surfaces may be inclined, as shown with regards to
The sliding plate 42 may be provided initially on the ski-binding 2 as is shown in
The sliding plate 42 may be received in a cavity or the like located in the ski-binding 2, or it may be received on a top surface of the ski-binding 2. Equally, some form of housing may be provided to store the sliding plate 42 when the sliding plate 42 is not in use, i.e., when it is in the unlocked position. In one embodiment as shown in
Although the sliding plate 42 is shown with a lever 8 that is integrally formed with the ski-binding 2, the sliding plate 42 may be provided with a separate lever 8 that is attached to the ski-binding 2.
A preferred embodiment of the lever 8 and locking means 34 is shown in
Generally, in the embodiment of
In order to increase the amount of flexibility, a second recess 106 may also be provided as shown in
In all of the above examples, the lever 8 may be provided with one or more guides or tracks 108. An example of such a track 108 is seen in
Although not shown, the leading edge of the sliding plate 42 may additionally or alternatively be provided in a sloped or curved manner. That is, for example, the leading edge may be provided as a slope with a gradient that corresponds to the gradient of the biased lever 8. In this way, when the leading edge of the sliding plate 42 contacts the top surface of the lever 8, or the track(s) 108, a maximal contact area between the leading edge and the top surface or track(s) 108 is provided. This may reduce the wear on the lever 8, leading edge of the sliding plate 42, and/or the track(s) 108. In another configuration, the leading edge may be curved so as to gradually contact the lever 8 or track(s) 108.
The sliding plate 42 may also be locked once in the locked position; that is, once the sliding plate 42 locks the lever 8 in the engaged position, the sliding plate 42 may itself be locked in order to prevent movement of the sliding plate 42. In this regard, the protrusion 44 of
Although only one indented portion 112 is shown in
In another configuration, the sliding plate 42 may engage with a recess provided in the ski-binding 2. A longitudinal recess may be provided on the same plane as the sliding plate 42 such that the sliding plate 42 slides into the recess when actuated into the locked position. This may lead to an arrangement where a part of the sliding plate 42 covers a part of the surface area of the lever 8 and a part of the ski-binding 2. The lever 8 is therefore unable to return to the biased disengaged position owing to this arrangement.
The sliding plate 42 is preferably a substantially planar structure. In some cases, it may be that the sliding plate 42 has one or more edge portions that engage an edge of the lever 8. For example, a C-shaped lip 110 may be provided on the left and right sides of the sliding plate 42 to engage the left and right sides of the lever 8 respectively. An example of a C-shaped lip is shown in
It should be appreciated that any combinations of the locking means 34 discussed above may be employed in co-operation with each other. For example, a sliding plate 42 may be provided in conjunction with the protrusions 38 and/or side protrusions 46, for instance. Providing a combination realises a fail-safe arrangement, should any of the locking means 34 fail.
As mentioned above, the lever 8 may be integrated with the ski-binding 2.
When the lever 8 is formed as an integral component with the ski-binding 2, the lever 8 may be biased to the engaged or the disengaged position depending upon the preferred configuration. The present invention is not particularly limited to which position the biasing is directed.
Alternatively, the lever 8 may be a separate component and fixed or attached to the ski-binding 2. In one configuration, the proximal end 26 of the lever 8 is provided with a mounting block and the interface between the mounting block and the proximal end 26 is provided with the weakened portion 52 discussed above. In this arrangement, the mounting block is fixed to the ski-binding 2 and effectively operates in the same manner as the integrated lever 8 discussed in
An alternative is shown in
Many other possible attachment methods or means may be utilised, and the present invention is not limited to those discussed above. Indeed, as long as the attachment means enables the rotatable or pivotable attachment of the lever 8 to the ski-binding 2, any means may be used.
The present invention may also provide a mounting plate 4 adapted to be used specifically with the locking mechanism 6 or ski-binding 2 including the locking mechanism 6 described above. Conventional mounting plates 4 provide at least two sets of notches 12, one set adapted to receive a front facing lug and one set adapted to receive a rear facing lug, when two locking mechanism 6 are used. As the present invention explicitly employs only one locking mechanism 6 and does not include a second locking mechanism 6, the mounting plate 4 of the present invention requires only one set of notches 12. In this regard, a set of notches 12 is defined as a plurality of notches 12, wherein each notch 12 of the plurality of notches 12 has the same profile and is orientated in the same direction. With reference to
In operation, a skier wishing to alter the position of the ski-binding 2 firstly comes to a stop and may disengage the ski-boot from the ski-binding 2. While it is envisaged that the adjusting of the ski-binding 2 may be made while the ski-boot is attached to the ski-binding 2, particularly for cross-country skis where the ski-boot pivots at the toe portion, it is preferred that the skier will dismount from the skis. Once dismounted, the skier will actuate either the lever 8 or the locking means 34 (if the locking means are the sliding plate 42 or side clips 50, for example). The skier will then either actuate the lever 8 to the disengaged position or allow the lever 8 to return to its natural, biased position, and subsequently push or slide the ski-binding to the desired location. Once positioned appropriately, the skier then either presses the lever 8 in the notch 12 manually or by moving the sliding plate 42 to the locked position, or simply releases the lever 8 if biased to the engaged position into the notch 12. Thereafter, the locking means 34 is actuated, if not already done so by inserting or pressing the lever 8 into the notch 12, and then the skier remounts the skis.
The overall process is far quicker than adjusting several different levers at any one time, and provides the skier with the most control for adjusting the ski-binding 2 accurately and precisely.
The present invention provides an easy and quick adjusting mechanism for adjusting the position of a ski-binding 2 by utilising only one locking mechanism 6 including only one lever 8. Because a second lever 8 or a second locking mechanism 6 is not provided, a skier operating the locking mechanism 6 is provided with only one lever 8 to actuate in order to fully adjust the position of the ski-binding 2 to the desired position.
