1. Field of the Invention
The invention generally relates to land vehicles of the type broadly considered to be skates, which can be defined as devices to be secured to the feet of the rider whereby he may propel himself over land, ice or snow. The invention is particularly directed to shoe attaching means of the type referred to as ski fasteners, which are more commonly referred to in the art of skiing as ski bindings. According to the present invention, a ski binding may be of substantially any description but may consist of toe and heel fasteners. The binding is mounted on a common support plate or first element, wherein the plate is movable or releasable from the ski. A second element installed on the ski mates with the first element in response to compressive forces applied between them. The invention provides the ability to install and remove one's ski bindings from various sets of ski's without the use of hand tools.

Conventional ski bindings are used to attach a pair of ski boots to a pair of alpine skis. These bindings generally have a mounting area that creates a large flat spot in the natural bending arc of the ski. This flat area can be in excess twenty linear inches along the length of the ski. This area can degrade the cutting effect in the turning pattern of the ski while a skier is attempting to make an aggressive turn. When the skier applies force while turning, the ski is bent into an arc by three points on the ski: the tip, the tail, and the middle. The flattened area will create a scrub portion that is not in line with the rest of the natural arc. This scrub degrades the ability of the skier to make the tightest, most accurate turn possible. This scrub also creates a loss of energy and forward momentum.
Conventional ski bindings are generally used at fairly high speeds, on a variety of terrain. In certain situations, the ski can vibrate and generate a bounding effect that the skier feels. There are no vibration-damping systems incorporated into modern ski binding systems. When vibration is encountered on choppy terrain, it can cause numbness, fatigue, and pain to the skier. The bouncing affect can also cause ski chatter, where portions of the ski are not cutting into the snow, which results in a loss of traction and hinders the skier from performing an accurate, efficient, and safe turn.
Generally, conventional ski bindings are permanently mounted to a set of skis. A ski binding is quite costly, with cost increasing with quality and protective ability. As bindings are designed to protect the skier from injury, the skier has strong motivation to purchase highest quality, most expensive binding he can afford. When a skier purchases a new set of skis, he has the option to reuse his old set of bindings by transferring them to his new set of skis. This option results in the old set of skis having no bindings and for that reason becoming worthless. The skier's other option is to purchase a new set of bindings, which then are permanently mounted to the new set of skis. This option can be costly and, of course, results in the new set of bindings being permanently committed to the new set of skis. A set of ski bindings must be accurately mounted to a pair of skis in order to use them safely. Installing or transferring a set of bindings tends to be a professional job for a technician at a ski shop, using proper tools, which adds both monetary cost and significant time delay to any installation. Current bindings are meant to be affixed in a manner such that the skier, himself, does not have the ready ability to swap them from one set of skis to another. The practical result of the current situation is that a skier must have a number of ski bindings equal to the quantity of his functional skis.
A typical ski is manufactured with a set camber. This curvature profile dictates the overall handling characteristics of the ski. There are currently no methods in place to alter this manufactured profile, to thereby change the handling characteristics of the ski. Current ski models are designed with one specific profile for one specific type of skiing/terrain.
It would be desirable to create an engagement between a ski binding and ski that substantially eliminates the scrub portion of the ski's curvature during turns. According to the invention, this can be achieved by mounting a ski binding to a ski via an intermediate binding mounting plate that is connected to the ski on a footprint that is substantially shorter than the length of the binding. The shorter footprint results in a reduced length of the scrub portion.
It would also be desirable to create a ski binding that is capable of selectively controlling vibration and bounce in the operational characteristics of a ski. It would further be desirable to enable the vibration and bounce control system to be variable in effect, to be adaptable to skis of different performance characteristics. According to the invention, this can be achieved by employing an intermediate binding mounting plate to carry the binding and to be mounted to the ski on a shorter footprint than the length of the binding. The binding mounting plate provides end portions beyond the small footprint, and these end portions can be mounts or holders for vibration damping elements.
It would be desirable to create a ski binding that is capable of selectively altering the handling characteristics of a ski. More specifically, it would be desirable to create a ski binding that can selectively alter the camber of a ski. According to the invention, this can be achieved by employing an intermediate binding mounting plate to carry the binding and to be mounted to the ski on a shorter footprint than the length of the binding. The binding mounting plate provides end portions beyond the small footprint, and these end portions can be mounts or holders for camber altering elements.
Finally, it would be desirable to create a quick release mounting device that permits quick mounting of a binding onto a ski, and quick release of a binding from a ski. Such a quick release mounting device would enable an entire binding to be moved from one pair of skis to another, preferably in a short time frame such as a minute or less, and preferable without the use of tools.
To achieve the foregoing and other objects and in accordance with the purpose of the present invention, as embodied and broadly described herein, the method and apparatus of this invention may comprise the following.
In one embodiment, a kit provides suitable elements to convert the normal, direct and permanent mounting of a binding to a ski into a nonpermanent, quick install and quick release mounting. The kit provides at least a two-part mounting system, in which one part is permanently affixed to the top of the ski at the normal binding mounting area, and the second part is permanently affixed to the bottom of the binding. The two parts of the mounting system can be engaged by temporary mounting means, which allows quick engagement and quick disengagement of the two parts from one another. For purposes of this description, mounting screws are considered to be permanent.
Temporary, quick release mounting means is considered to include systems in which the two parts of the mounting system are quickly engaged by being pushed together with compressive force and then the two parts or their subcomponents are moved transversely to the direction of compression to lock the two parts together. Reversing the transverse motion and then lifting the two parts apart quickly disengages the two parts. Such a system enables the quick engagement or disengagement of a binding from a ski, and then enables the reengagement of the binding on another ski that has a similar mating element mounted on its top.
Suitable transverse motion of the quick release mounting means can include sliding of one or more lock plates in a system where the lock plates are the first part of the system and large headed fasteners are the second part of the system. A pair of lock plates can slide apart to open, enlarge, or reposition apertures to receive the heads of the headed fasteners. The plates can slide to close and capture the heads, and can slide to reopen and release the heads. Another transverse motion is between the first and second parts of the system, where the system is formed of a pair of matable slide plates in which one has lugs and the other has slots that fit the lugs. Longitudinal sliding motion between the plates can engage the lugs in the slots or disengage the lugs from the slots. Another configuration of matable slide plates employs rotary sliding, where one plate has opposite ends that perform similarly to lugs, and the second plate has slots that can receive the ends by rotation of one plate with respect to the other. All of these transverse motions can be performed in a matter of seconds, without requiring tools.
Such a conversion kit may provide a binding mounting plate that can serve as an intermediate carrier for the binding, between the binding and the ski. A binding mounting plate can be specially configured to receive one of the elements of the two-part mounting system on its bottom face. The binding can be mounted on its top face. The binding mounting plate may have a preselected length that is longer than the mounted part of the two-part mounting system and longer than the binding. The length of the binding mounting plate can provide oppositely extending end portions that assist in mounting vibration dampers and camber adjusters.
In a second embodiment, a ski and binding are modified by permanently affixing a first mounting element of selected configuration to the ski's top surface at a longitudinal position centered where bindings conventionally would be installed. The binding is modified by being directly mounted to the top of an intermediate carrier that is interposed between the binding and the ski. Two-part, quick release mounting means can be attached between the ski and the binding mounting plate, with a first mounting element of the two-part system attached to the bottom of the binding mounting plate and with a second mounting element of the two-part system attached to the top of the ski. The two parts of the mounting system can be temporarily attached to each other with sufficient security to allow skiing to be performed using the binding and ski.
The intermediate carrier not only provides a means for attaching a ski binding, but it provides a sufficiently stable mounting to the ski that the mounting element on its bottom face can be shorter than the length of the binding. Thus, the two-part mounting means can be attached to the ski over a shorter length footprint than the length of the direct mounting structure for a binding. The result is that the mounting footprint of the binding on the ski is relatively shorter than for a directly mounted binding, itself, and the scrub portion of the ski, if any, is reduced.
The mounting element on the intermediate carrier and the mounting element on the ski attach to one another by compression, which is a quick method of mounting the binding to the ski. In one embodiment that features compression, the first mounting element of the pair, which is attached to the top of the ski, is an array of mounting pins with enlarged heads. The second mounting element of the pair, which is attached to the bottom of the binding mounting plate, includes an array of apertures that can alter their shape to snap over the enlarged heads under directly applied compression of the binding mounting plate against the mounting pins. The mounting pins may be permanently affixed to the ski by conventional ski binding mounting screws.
The second mounting element that is attached to the bottom of the binding mounting plate allows the binding mounting plate to be quickly attached to or released from any ski that is equipped with a mating first mounting element. Conventional ski binding mounting screws, as the manufacturer typically supplies with the new bindings, are suitable to permanently mount the binding to the binding mounting plate. The second mounting element is placed over the mounting pins on the ski and pushed downwards, which locks the second mounting element to the mounting pins. The pins are configured with guide surfaces to assist in aligning the pins with the receivers of the second mounting element. The guide surfaces are tapered top edges of the pins, which assist in guiding the second mounting element when it is pushed down over the pins.
A suitable locking mechanism of the second mounting element is a two-part slide lock. Applying the slide lock to the mounting pins separates the two parts of the slide lock mechanism to receive heads of the mounting pins. These two parts of the slide lock are kept in a normally locked position by action of springs on either end of the slide lock. When the slide lock is fully seated over the heads, there is sufficient room under the heads for the two parts of the slide lock to snap into closed position under the received heads, locking the slide lock to the ski. Manually operated slide buttons can open the slide lock for removing the slide lock from the ski.
As one example of suitable mounting points on the ski, an array of six mounting pins can be used, and correspondingly the slide lock mechanism is configured to receive this array of pins. The slide lock mechanism provides tapered guiding surfaces to assist in receiving the tapered heads of the mounting pins into corresponding locking receptors. Once pins are fully seated in the receptors, the two plates will slide back into their resting position, partially closing under the enlarged pin heads to lock the pin heads behind the two plates. These two plates slide in opposite directions so that in the event that one plate becomes jammed in an unlocked position, the second plate will still hold the pins in place, keeping the binding and quick release binding mounting assembly affixed to the ski. In a resting state, the two springs of the slide lock mechanism act in opposite directions to push the two locking plates towards each. This provides a safety guard against unintentional release of the slide lock if the skier encounters a large jarring motion in a single direction. In an extreme circumstance, one plate could become unlocked momentarily, but the other plate, being spring-loaded in the opposite direction, would snugly hold the binding mounting plate to the ski.
Another embodiment of the first mounting element is a lower slide lock plate that is permanently attached to a ski's top surface at a longitudinal position centered where bindings conventionally would be installed. The lower slide lock plate defines an array of laterally extending lugs along each side edge. The lower slide lock plate may be affixed to the ski by conventional ski binding mounting screws. The second mounting element is an upper slide lock plate configured to mate with the array of lugs in complementary, mating, lug receptor cavities and longitudinal channels. The mating upper slide lock plate is pushed down on the lower slide lock plate to receive the lugs in alignment with the mating cavities. Then the upper slide lock plate is slid longitudinally to cause the lugs to enter the longitudinal channels, thereby fastening the binding mounting plate in place. When the lugs are fully received in the channels, a suitably positioned spring-loaded latch locks the upper and lower slide lock plates against reverse sliding motion. A latch release mechanism can open the latch to permit removal of the binding mounting plate from the ski.
The binding mounting plate can be equipped with an integral dampening and tuning system, allowing the user to tune the flexibility and curvature properties of the ski, as well cushion the vibrations endured while skiing. In downhill racing, a ski that is properly tuned for the conditions of the course can cut critical seconds off of the skier's run time. This tuning system is comprised of a plurality of swappable blocks of different densities. Selected blocks can be installed under the binding mounting plate at leading and trailing end locations, which are disposed respectively towards the toe and heel ends of the binding mounting plate. The blocks are swapped out by the user without the use of tools, while the binding mounting plate is temporarily removed from the ski, and are located and kept in place by pins in the bottom of the binding mounting plate.
An optional modification of the damping system allows the damping blocks also to change the camber or arc of the ski. In a configuration that does not change the camber of the ski, the damping blocks are configured to follow the curvature of the ski. In an alternative configuration that changes the camber of the ski, the outer ends of the damping blocks are sufficiently larger or thicker than the inner ends, such that the end or the binding mounting plate pushes down the outer ends against the ski to shorten its radius of curvature. The shortened radius corresponds to a more aggressive camber.
The entire binding mounting plate, including damping and camber changing components, can be quickly removed from the ski using no tools. The purpose of having a binding mounting plate, with a quick release binding mount assembly, would be for the user to have the ability to swap one set of expensive, high end bindings onto various sets of skis, without suffering the expense of purchasing multiple sets of bindings for corresponding multiple pairs of skis. A quick release binding mount assembly would be useful to ski racers, to consumers with multiple sets of skis for various skiing conditions, to rental markets, and to demo shows where many skiers are riding many alternate sets of skis in one day.
The first mounting element on the ski and the mating second mounting element on the binding mounting plate are located directly underfoot, in a lengthwise footprint that is as compact as possible in order to provide the ski with an un-encumbered flex pattern. For example, both the described array of mounting pins and the mating slide plate are substantially shorter than the length of a conventional ski binding. The side profile of the binding mounting plate is shaped to avoid contact with the ski other than via the mounting footprint, to allow the ski to flex in a perfect arc. The binding mounting plate is designed with a curved side cutout to allow the ski to curve in a natural form without flat spots and hindrances.
According to the invention, no tools are required to swap a set of bindings from one set of skis to another. The entire quick release binding mount assembly is designed with speed and ease of use in mind. Each set of skis would require only the installation of one side of the mating mounting elements. For example, the pins or slide lock plate, as appropriate to the system being employed, must be mounted to each ski. These components are simple and inexpensive. The far more expensive ski bindings are attached to the binding mounting plate, which is portable and can be transferred from one pair of skis to another. It is anticipated that a user can swap a pair of bindings from one set of skis to another in about ten seconds.
The accompanying drawings, which are incorporated in and form a part of the specification, illustrate preferred embodiments of the present invention, and together with the description, serve to explain the principles of the invention. In the drawings:
The invention is a quick release ski binding mounting system 20, shown in
To complete the process of engagement, the compression may be accompanied by a transverse mechanical movement in a direction other than normal to the top surface of the ski, such as longitudinal sliding, rotation, or separation of spring-loaded components approximately transverse to the direction of compression. Disengagement for removal of the binding requires more than lifting tension between the binding and ski, so that the binding is secure on the ski for safe performance of the skiing sport. The release of the ski from the binding requires mechanical motion within the two-part mounting device in a direction other than normal to the top surface of the ski, such as transverse to the normal direction.
The changeover of bindings from one set of skis to another can be accomplished quickly enough that the user can change his skis during a single ski day or even within a matter of seconds. The binding mounting system optionally provides selective vibration damping and ski camber adjustment. Damping and camber adjustment are changeable by substituting components of the binding mounting system, which can be accomplished with similar ease and without tools.
The term, “ski binding,” means a complete, functional device for attaching a shoe or boot to a ski, needing only to be first attached to the ski. A ski binding is configured to be mounted on a ski using a mounting structure that extends over a predetermined length of the binding. The typical mounting structure is known to be screw holes that receive mounting screws. The screw holes are known to be located near the opposite ends of the binding. Thus, the length of the binding is a reasonable estimate of the length of the mounting structure associated with the binding. The length of the mounting structure is predetermined, even if the binding accommodates adjustments in length. Known types of bindings include heel and toe bindings, which are composed of a heel piece and a toe piece that are mounted at a predetermined separation from one another, according to the approximate size of the user's boot. Often the heel or toe piece is on a mounted base plate and can be longitudinally adjusted on the plate to vary the intermediate separation to accommodate variation in boot sizes, such as between brands of boots. Another type of ski binding is a heel and toe plate binding, in which heel and toe receivers are mounted on a base plate that carries both and perhaps allows adjustment of the intermediate separation. However, such a binding requires the base plate as a component thereof. Still another type of binding is a plate binding having a base plate that engages a boot sole plate. The user must attach the sole plate to his boot, and the base plate carries a mechanism that engages the sole plate instead of engaging the boot.
The terms “binding mounting plate,” “intermediate carrier,” “intermediate binding mounting plate” and the like refer to a mounting surrogate for the ski, itself, and not to an integral part of the ski binding. The invention relates to such a surrogate and to its use to carry the complete binding, of whatever description.
The terms, “first and second mounting elements,” “mating mounting elements,” and the like refer to two-part mechanisms that enable the quick release and quick mounting of ski bindings. One of the two mounting elements is attached to the ski at the normal binding mounting area by a secure, relatively permanent method such as screws. Mounting elements of this type may be attached to as many skis. The other of the two mounting elements is attached to the binding by a secure, relatively permanent method such as screws. A quick engagement and quick disengagement mechanism operates between the two mounting elements to enable the binding to be disengaged from one ski and engaged on a mating mounting element of another ski.
With reference to
The mounting plate has a top wall with a smooth top surface, which enables the components of a ski binding to be mounted at longitudinal positions as required by the binding manufacturer's specifications, using accepted fastening devices such as screw fasteners. The top wall is folded down to form side walls 27 of the mounting plate. The folds increase structural rigidity. At the support zones, the folded sides 27 are cut on a curve or tapered toward opposite ends of the mounting plate so that when the mounting plate is mounted on a ski, the ends have a clearance from the ski or follow the curvature of the ski, thereby allowing the ski to flex into a curve without interference from the ends of the mounting plate. The bottom of the mounting plate is configured for interconnection with additional elements, as selected or required. For example, the bottom face of each support zone 24 is configured with means for engaging damping and camber adjusting elements. As examples of such engaging means,
As shown in
A representative dampener 46, shown in
The user's ski is equipped with means for selectively receiving and selectively retaining the binding mounting plate 22. As an example, suitable mounting points are applied to the user's ski, at an area central to the conventional binding mounting location of the ski. The mounting points are configured to mate with the binding mounting plate. Together, the mounting points and the binding mounting plate form the simplest embodiment of the quick release ski binding mounting system 20. The mounting points cover a shorter portion of the ski's length than required for a full binding, with the result that the ski is better able to flex in a natural arc, with less scrub area than would result from a conventional binding mounted directly to the ski.
As one embodiment of mounting points, a plurality of ski mounting pins 50, as shown in
The height of a shank 56 is equal or greater than the height of a locking plate 38, 40 or an aperture 62, with the result that the locked apertures not only grip the shanks against movement in length and width but also secure the ski mounting pins against movement in height.
As shown in
The view of
The components 78 may be combined in a sandwich structure. A top layer 80 is a relatively stiff, camber increasing layer. Examples of possible materials of construction include carbon fiber and metals, such as aluminum and titanium. The bottom layer 82 is a relatively softer, vibration damping layer. Examples of possible vibration damping materials of construction include resilient materials such as rubber, elastomers, and plastics. The binding mounting plate 22 applies the extending ends of components 78 with mechanical advantage against the top of the ski 76. The applied stiff layer 80 operates against ski 76 to adjust camber. Softer, damping layer 82 damps vibration over its extended length, thus increasing damping efficiency. In addition, the damping layer 82 isolates the ski from abrasion against stiffer layer 80.
The mating mounting element is binding mounting plate 90 of
In use, the binding mounting plate 90 is pushed down on the slide lock plate 84 to receive the lugs 86 in the mating recesses 94 of plate 90. Then the quick release binding mounting plate 90 is slid longitudinally to cause the lugs 86 to enter the longitudinal channels 98, thereby fastening the quick release binding mount assembly in place. The binding is removed from the ski by the reverse procedure.
With reference to
A cross-shaft 106 of lever 102 is mounted on the binding mounting plate 22 at the longitudinally fixed location of apertures 108 in side walls 27, roughly at the midpoint of the length of the binding mounting plate 22. The cross-shaft fits into a transverse position control cavity 109 in the slide plate 100. A cam 110 on the cross-shaft acts against at least one of the fore or aft cavity walls to reposition and secure the slide plate. When lever 102 is in a selected end position, such as to the right in
Raising the lever 102 by about one-quarter rotation, to an upright or normal position to the binding mounting plate 22, releases the cam from securing the slide plate 100 in fixed longitudinal position. The slide plate 100 is free to move longitudinally, which allows the pins 50 to be released from openings 104. The upright, released position of lever 102 is a safety feature because it prevents the binding from being used until the lever is lowered to locked position.
The binding mounting plate 22 carries the centrally located slotted bodies 122 that define opposed reception slots. The binding mounting plate 22 can be installed on the ski by placing the fastening zone 26 of plate 22 over the position of locking plate 114 on the ski, at an angle of about sixty degrees as suggested by
A binding mounting plate 132 of
In use, the binding mounting plate 132 is pushed down on the slide lock plate 134 to lower the cover tabs 142 below the level of lugs 136. Then the binding mounting plate 132 is slid longitudinally to cause the lugs 136 to enter the pockets behind cover tabs 142, thereby fastening the binding mounting plate in place. The binding is removed from the ski by the reverse procedure.
In the various embodiments of the invention described, above, components of the quick release system are a mated pair or cooperating first and second elements. These elements can function whether in the described position or in a reversed position. Thus, one component of a mated pair has been described as an element of the binding mounting plate, while the other component has been described as an element of the ski. As such, the mated pair can function similarly whichever is mounted to a ski and whichever is mounted to the binding mounting plate. It should be understood that a reversal of the components is within the scope of the invention.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be regarded as falling within the scope of the invention.
