This invention relates generally to ski boots, and specifically to ski boot protectors and traction aids.
This invention was not made under contract with an agency of the US Government, nor by any agency of the US Government.
Ski boots are specialized boots which serve several functions. They are intended to retain the warmth of the user's foot in cold conditions. Famously, they move the site of any broken leg up the shin bone and away from the ankle, thus providing an easier medical fix in the event of a broken leg.
On a more mundane level, ski boots are designed, dimensioned and configured to physically cooperate with a ski binding so as to lock the boot and the ski together firmly, thus allowing the user to control the ski with confidence and precision. The fittings, projections and indentations on the ski boot sole exactly match (in a complementary match) the fittings, projections and apertures on the ski binding, indeed, the size and shape of the planform or outline of the boot sole is crucial to this physical engagement to the ski binding. The planform of a ski boot sole is a squared off rectangle very different from practically any other type of footwear. The sole has a specific shape and size in addition to having various devices thereon, and the primary purpose of these devices and the shape of the sole is simply to provide a secure and strong engagement to the ski. As a result, a ski boot in outline and planform resembles no other footwear. The sole may project at front and/or back, the sole may be a considerably narrower shape than the uppers of the boot above it and so on.
Walking on ski boots is initially disconcerting, but most users pick up the trick quickly. After that, a pair of new problems with walking on ski boots quickly emerges. The first is lack of traction. The ski boot is not shaped for walking with good traction, rather it is shaped to fit to a ski binding. Unlike most footwear, it is even possible to lose traction and have a foot slip sideways. Front and back slips occur frequently too, especially considering that most ski boot walking occurs on the icy surface between the parking lot and popular ski runs or on the tile floors many “bottom of the ski run” businesses provide for their customers. This problem tends to yield to practice on the part of the user, which only exacerbates the other problem: damage and wear on the ski boot soles.
The devices on the ski boot sole are not intended for walking, they are precisely designed for physical engagement to ski bindings. The devices (generally “projections, indentations and fittings” in this application) are easily damaged or worn by being used as traction devices or treads by walking users. Even short walks can damage the devices enough to cause problems or even safety issues, since the fit of sole to binding is very precise in some regards. Most ski boot soles are quite strong materials which the maker may hope will minimize such issues.
One known solution to the traction issue is the family of hard plastic snap on devices which have numerous cleats on one side and on the other side fit either the toe or heel of the ski boot. This solves traction problems and even provides a degree of protection at ski boot toes/heels. —However, the mid-section of the sole remains largely exposed to the hazards of ice, rocks, debris, door sills and the like.
A problem with such rigid devices is that they are also somewhat difficult to handle and store when not in use, being essentially squares of hard plastic with cleats on them. A worse problem is that in use, such devices can be fiendishly difficult to put on and take off. The non-elastic plastic construction means that the user has to struggle to get the device in place. The shape and configuration of such devices further ensures that it is very difficult to tell front from back while bundled up and wearing ski goggles.
Two other problems occur with the hard plastic snap on devices. The first such problem is that the devices tend to stretch over time. As a result of stretching, they eventually begin to fall off. While walking, the normal skier simply has very little ability to see such devices at all, as they attach to the bottom of the ski boots. In addition, the typical walker in ski boots concentrates on skis, poles, packs, lift tickets and similar encumbrances. Thus, the absence of the traction device may go un-noticed. The second problem with such devices is that makers tend to compensate for the stretching problem by making the tolerances of the devices as tight as possible, thus making the devices even harder to get on or even off. A fully encumbered skier must then fight with a device securely attached to the bottom of the ski boot when new, or stretched and absent when old.
In the unrelated field of more mundane footwear, a different problem has led to a different structure for solution. Dress shoes may be equipped with a rubber “partial galoshes” which comprise a unitary rubber tread and minimal upper of one or two inches tall (2.5-5 cm tall). Being a single unit of rubber makes such devices water proof, allowing wearers of dress shoes to chance muddy city streets with a bit less trepidation. Such devices cannot fit onto a ski boot, being dimensioned and configured to fit upon a normal dress shoe.

General Summary
A ski boot protector fits on the sole of a ski boot due to being dimensioned and configured to wrap around the sole of the ski boot at the toe and heel of the ski boot, even extending across a portion of the top of the projecting sole. An elastic or rubber upper portion holds a fabric, rubber, polymer or other material body front and back invention sole portions in place, a flexible tread provides protection for the ski boot sole from the ground, snow or ice walked on while being flexible enough to allow the device to roll up for easy storage in a pocket when not being worn. Large loops, tabs or other projections are dimensioned and configured to allow a user to easily manipulated the device wearing ski gloves, a hook or a hook-and-loop fabric band may be used to hold the device to its companion device or to hold it in the rolled up position.
A hook or an arrow and barb shaped device or hook-and-loop fabric band may also be used to store the device around the boot shaft while the user is skiing and thus not using the device.
The device may in alternative embodiments also have a flexible, rollable sole having a thin elastic or rubber cord attached thereto in parallel to the edge of the sole but attached at a distance from the sole, so that the elastic cord may fit around the ski boot at the junction of the sole and upper, the elastic cord of a size sufficient to extend around the boot at the level of the sole but small enough to exert a physical engagement to that it may not easily slip back over the sole. The attachment may comprise a plurality of extensions of the plastic or rubber cord. An elastic cord for purposes of this application is one that is a combination of rubber cord and fabric or is simply a fabric which itself is stretchable like rubber, and significantly, allows a user to quickly determine front and back ends of the device even under snowy conditions.
In the presently preferred embodiment and best mode now contemplated, the device may also have a pair of soles sufficient to completely or partially cover the ground contacting portions of a ski boot sole (toe and heel), and with a rising upper at the toe and heel to surround the vertical thickness of the ski boot toe and heel and short lip around the top ends to project onto the top portion of the boot sole, with a short gap between the heel sole and toe sole, so as to further increase flexibility and allow even easier rolling and storage.
Embodiments of the device may be made by injection molding, compression molding or the like.

Loop projection 2 is securely attached to the device either at upper portion 1 or body 2 or sole 4. Loop 2 is dimensioned and configured to allow easy manipulation by a user wearing bulky ski gloves. In particular, loop 2 is large enough to allow easy gripping. Loop 2 may in alternative embodiments be a tab, a projection of other types, thin rope, twine, may also be elasticized (for example as an elastic cord or rubber cord), a fabric strap or combinations thereof. Loop 2 serves additional functions as discussed below in relation to
Sole 4 is in the preferred embodiment a rubber or rubber related compound thick enough to both provide substantial shock absorption to the ski boot sole it protects and also thick enough to take a substantial tread for improved traction by the wearer. Sole 4 in the preferred embodiment covers a substantial portion of the surface of body 3 (corresponding to over 80% of the surface area of the bottom of the ski boot), but in alternative embodiments it may be smaller (thus reducing weight and size and making storage easier when not in use) or it may be larger (extending to the portions of the body 3 which correspond to the “uppers” of the device), thus providing protection to the sides of the ski boot sole as well as the bottom.
The nature of a ski boot sole may be seen in these diagrams, which show that the sole is quite thick, far thicker than the soles of ordinary footwear, and the ski boot sole may well extend (as shown in
Ski boot 6 has an ankle portion extending upwards from the “foot” or “uppers”. This ankle portion may be used to store the device of the present invention. In particular, the device has strap 5 attached securely to body 3, upper portion 1 or sole 4. Strap 5 may have thereon a hook-and-loop style of fabric such as VELCRO™ brand hook-and-loop fabric, so that strap 5 may attach to a patch of the complementary (loop or hook) type fabric also securely attached to strap 5 itself, or in alternative embodiments to body 3, upper portion 1 or sole 4, or in addition on projection/loop 2. In use, loop 2 and strap 5 are engaged by passing one through the other. Strap 5 is then attached to the patch of complementary fabric also located on strap 5 and the device is securely attached around ski boot 6. In the preferred embodiment, both complementary pieces are on strap 5.
In addition to or in place of hook-and-loop fabric, buttons, snaps, zips, magnets and other fasteners may be used in alternative embodiments.
The size of the device may be chosen as follows: the dimensions and configuration of the device may not only cover a ski boot sole or important portions thereof which require protection in use, but in addition the device may be dimensioned and configured to pass around the boot ankle in storage, and to be secured thereon without excess slack. Elastic rim/upper portion 2 may be an aid in this: the length of the body, projection, and strap may be just slightly less than the circumference of a ski boot ankle when the elastic upper portion is in the relaxed first position, but sufficient to go around when the elastic upper portion is in a stretched second position. The elastic/rubber rim, of course, may have a stretched third position achieved when stretched around the boot sole in use position.
It will be seen from
When the device is in use, the skier can easily see the elastic/rubber brim running along the edge of the boot above or along the actual sole of the boot. In addition, donning and removing the device is quite easy, even encumbered: the skier may insert either end in the foot or heel, as appropriate, of the boot and then stretch the rest over the other end of the boot. In embodiments, the device may be “double ended” with a less specific “foot shape” to the tread, so that either end may go onto the toe or heel of the boot.
Secure attachments of the parts to each other may be achieved using sewing/stitching, adhesives, bonding, vulcanizing, riveting, and combinations thereof. One embodiment presently preferred (see
Heel end 102a and toe end 102b of the sole 102 may be dimensioned and configured differently: heel end 102a may be dimensioned and configured to cover and protect a ski boot heel, while toe end 102b may be dimensioned and configured to cover and protect a ski boot toe.
Flexible, extensible cord 104 has a relaxed state and a stretched state. The overall length (or circumference) of cord 104 may be at least approximately equal to the circumference of a ski boot sole. For example, the relaxed state of the cord may have length less than the circumference of the ski boot sole, so as to not be able to pass over the sole when relaxed, but the stretched state may be slightly greater than the circumference of the ski boot sole, so that when the user pulls the cord, it may pass over the sole of the ski boot. Thereafter, when released back to the relaxed state or a third “partially relaxed” state (held from complete relaxation by the boot), the extensible cord 104 may stay on the sole of the ski boot due to the physical engagement of the cord over the sole (at the junction of the upper/body of the ski boot and the sole).
Flexible, extensible attachment 106 may be the same material as the cord, and may be extension thereof, or it may be a different material, or in embodiments even not extensible. Attachment 106 (other attachments shown in
The device still functions as a ski boot sole protector, even without a complete sole from front to back because the intermediate portion of the ski boot sole is less prone to damage, tends to be higher off of the ground than the ski boot toe and heel portions, and because the thickness of the fraction aid sole will separate the ski boot sole intermediate portion from the ground surface in the area of gap 210.
The ski boot sole intermediate portion does not normally engage a ski binding in any case, so if were to become damaged it would not impact safety or the interface and physical connection to the ski.
Metal or hard traction aids such as studs, nails, spikes or the like may be used in alternative embodiments. Note that alternative embodiments having no metal/hard aids such as studs, spikes, nails or the like projecting from the bottom of the sole are preferred over other alternative embodiments having such sharp traction aids, but both such types of embodiments fall within the scope of the invention. The reason for this is that such relatively sharp traction aids render the device less safe when carried in the interior pockets: it may rip the lining, or should a skier take a spill with the device in a pocket, the skier may be injured by metal/hard traction aids poking through to the skin. Similarly, when the device is deployed around the ankle of a ski boot, hard projections like studs might present a threat to other skiers, especially in the event of a spill or wipeout. However, the alternative embodiments may be preferable for increased traction on icier surfaces or packed snow surfaces.
Tab 364 is an optional device which may aid in use of the device, however, loop 366 is dimensioned and configured to provide a much easier method of grasping and using the device, especially for pulling it on or off while wearing ski gloves. Ski gloves tend to be very thick, up to ½″ or more, so that a human finger of ½″ width in a ski glove (both sides of the finger) may be 1.5″ across. A two fingered grip on a device, or a thumb and finger grip, thus requires a substantial loop or projection to grab. Thus loop 366 may be at least one inch in length up to several inches in length so as to be dimensioned and configured for use by a user wearing ski gloves.
Sole traction devices 434 may be as discussed previously: one or more hard projections like spikes or in other embodiments, a plurality of projections of the material of the sole or something similar without spikes.
Loop 466, as discussed previously, may be one inch or several inches long so as to allow easy handling by a skier encumbered with proper hand wear. Fastener 468 may allow adjustment of the length of the anchor, so that the device may used on various sizes of ski boot soles, and may also have hook 470. Fastener 468 may be a device to tighten the overall size of anchor/cord 404 by pulling excess cord through fastener 468 and then preventing it from returning back through, thus tightening the cord 404. Such fasteners include spring loaded devices with holes through them, grommets, knots, buttons and the like.
In the position of storage around an arm, ski boot ankle or the like, the device may be wrapped/folded about a limb, clothing or boot and then hook 470 may be attached to loop 466, even by a user wearing thick ski gloves.
Placement of the hook and how it engages the other end of the device when not in use is susceptible to wide variations. The hook may be disposed upon the front end of the device or on the rear of the device at the loop and engage to the sole 462. In embodiments preferred for simplicity, the hook may be on the loop, on the elastic cords of the device, or in other similar locations at either toe or heel.
This embodiment may have soles and uppers of a relatively less flexible material due to gaps 510/584 allowing easier folding, however, in preferred embodiments flexible materials are desired, a finding confirmed by testing.
Sole half 1302 may have gap 1304 as previously described, with stretchable, flexible connector 1306 part of a web of connectors between the halves.
Crescent shaped traction bump/elevation 1308 may be advantageous to traction. It may in embodiments have other orientations than shown.
In this embodiment, the construction of the device may be a unibody construction in which the soles and the web of materials are all injection molded from a material such as a durable rubber, a somewhat elastic form of polymer or the like, a single body of fabric with elastic properties or the like. It is anticipated that unibody construction in which all soles and elastic rims, webs and so on are all a single piece will reduce manufacturing costs, making this aspect a preferred embodiment for this purpose.
It will be understood that embodiments will have a body or network or cords all having a stretched length, the stretched length sufficient to allow it to pass over the vertical thickness of ski boot soles at least at the heel and/or toe and in alternative embodiments all the way around the ski boot sole.
Boot 1590 has upper part of boot 1592 and the sole part of the boot 1594. The junction of the upper and sole is not uniform. Due to the necessity for ski boots to fit into ski bindings, the sole projects beyond the upper at a number of places, particularly front sole projection 96 and rear sole projection 1598. Each projection in turn has an upper surface, upper surface of rear projection 1586 and upper surface of front projection 1588.
These projections may be used to secure the device to the boot.
Front sole 1602 and rear sole 1604 may be seen to have not just traction enhancements (treads, bumps, grooves, etc) 1606 but also vertical portions, particularly at the front and back ends. Front and back vertical projections/sidewalls 1603 (see
First, second and third bands 1612, 1614, 1616 connect the two soles. Front lip 1630 and rear lip 1632, best seen in
When the device is in use, the skier can easily see the elastic/rubber brim running along the edge of the boot above or along the actual sole of the boot. In addition, donning and removing the device is quite easy, even encumbered: the skier may insert either end in the foot or heel, as appropriate, of the boot and then stretch the rest over the other end of the boot. In embodiments, the device may be “double ended” with a less specific “foot shape” to the tread, so that either end may go onto the toe or heel of the boot.
Secure attachments of the parts to each other may be achieved using sewing/stitching, adhesives, bonding, vulcanizing, riveting, and combinations thereof. One embodiment presently preferred has a unibody construction made by molding, injection molding, compression molding, extrusion or the like, using a rubbery material.
The device still functions as a ski boot sole protector, even without a complete sole from front to back because the intermediate portion of the ski boot sole is less prone to damage, tends to be higher off of the ground than the ski boot toe and heel portions, and because the thickness of the traction aid sole will separate the ski boot sole intermediate portion from the ground surface in the area between the front and rear soles.
The ski boot sole intermediate portion does not normally engage a ski binding in any case, so if were to become damaged it would not impact safety or the interface and physical connection to the ski.
Metal or hard traction aids such as studs, nails, spikes or the like may be used in alternative embodiments. Note that alternative embodiments having no metal/hard aids such as studs, spikes, nails or the like projecting from the bottom of the sole are preferred over other alternative embodiments having such sharp traction aids, but both such types of embodiments fall within the scope of the invention. The reason for this is that such relatively sharp fraction aids render the device less safe when carried in the interior pockets: it may rip the lining, or should a skier take a spill with the device in a pocket, the skier may be injured by metal/hard traction aids poking through to the skin. Similarly, when the device is deployed around the ankle of a ski boot, hard projections like studs might present a threat to other skiers, especially in the event of a spill or wipeout. However, the alternative embodiments may be preferable for increased traction on icier surfaces or packed snow surfaces.
In this embodiment, the construction of the device may be a unibody construction in which the soles and the web of materials are all injection molded from a material such as a durable rubber, a somewhat elastic form of polymer or the like, a single body of fabric with elastic properties or the like. It is anticipated that unibody construction in which all soles and elastic rims, webs and so on are all a single piece will reduce manufacturing costs, making this aspect a preferred embodiment for this purpose.
It will be understood that embodiments may have a body or network or cords all having a stretched length, the stretched length sufficient to allow it to pass over the vertical thickness of ski boot soles at least at the heel and/or toe and in alternative embodiments all the way around the ski boot sole.
Large loop 1608 is located at the front or rear of one sole. Note that the large loop has an extension shaped like an arrow: item number 1610 is an arrow shaped extension of material, not a reference arrow nor a direction of movement nor motion. The arrow shape of course is made up of an angled body portion having two barbs (1610a for both) and a stem portion (1610b).
The extension of the large projection has a tip portion at the end, this tip is pointed in the embodiment shown but can be other shapes.
Behind the tip of the extension is an angled body formed by two angled sides running from the tip to two barbs 1610a. The barbs 1610a extend from opposite sides of the angled body, and because of the barbs' width being greater than the width of the rest of the large projection, that is the stem portion 1610b, the barbs 1610a and stem 1610b from a true arrow shape, not a mere triangle shape. This is especially noticeable as each of barbs 1610a also has a rear side where the barb width returns to the width of the large projection step 1610b, not meeting each other in the middle (like a triangle would if the extension were a triangle with no stem) so that the barbs are well and truly formed.
Arrow shaped fastener 1610 is dimensioned and configured to pass easily through small loop 1618 located at the opposite end of the device as shown in
When a skier gets to the top of a slope, they may easily remove the devices from their boots and then wrap them around the upper part of the ski boot as shown in
Arrow shaped fastener 1610 also serves an additional function as an indicia. In particular, the prior art known (such as the 6044578 reference cited in the Background, similar products on the market and so on) all suffer from the deficiency of being somewhat androgynous of appearance as to front and back, yet the difference between front and back is sufficient that most such devices will not fit nor work properly if the user attempts to install them wrong way round. Since the typical skier is cold, in the snow, wearing goggles and wrapped up against the elements, large indicia are called for. Having the large loop, with an arrow, pointing to one end of the device, greatly increases the skier's ability to sort it out quickly for wearing.
