Description




FIELD OF THE INVENTION




The present invention relates to in-line roller skate constructions and, more particularly, to pivoting ankle support structures for in-line roller skates.




BACKGROUND OF THE INVENTION




In-line roller skates typically include a plurality of aligned wheels with parallel axles secured to a skate frame. A skate boot or shoe is attached to the top of the frame. Most skate manufacturers currently construct the boots and shoes (the “skate upper”) with a base, a plastic shell extending upwardly from the base, and a removable liner. The shell may include a cuff portion pivotally attached to a lower portion of the shell to ease fore and aft movement of the skater's leg while providing medial and lateral support. Alternatively the plastic shell may extend upwardly to the top of the skate above the ankle without the cuff being pivotally secured to the lower portion. Rigid hockey skates are also in the prior art. These skates typically do not have a plastic outer shell. Hockey skates may have a leather or leather/nylon outer shell with internal stiffening/support members. While hockey skate constructions provide necessary support for this sport they do not easily flex forwardly and rearwardly.




Most in-line roller skates are very maneuverable and are capable of higher speeds than those customarily associated with conventional paired wheel roller skates. In-line roller skating is generally considered to require higher levels of skill, coordination, and strength than conventional paired wheel roller skating because of the narrow, lateral support base associated with in-line roller skates. Specifically, while balancing in the forward and rear direction is relatively easy for even inexperienced skaters, balancing in the sideward or lateral direction is difficult because of the narrow support base and is heavily dependent upon the skater's balancing and coordination skills. Proper ankle and foot supports within the upper shoe portion of the in-line roller skate aid in lateral balancing.




To obtain the optimum performance from an in-line roller skate, it is important that the in-line roller skate be maintained in a substantially vertical position. The upper shoe portion of the in-line roller skate serves competing purposes of providing support and comfort; comfort in a shoe not usually being associated with a high degree of support. In other words, the incorporation of rigid support structures in the upper shoe portion of the in-line roller skate tends to add stiffness and bulk and, considering the warm weather environments conducive to in-line roller skating, tends to make the skates, heavy, hot, and uncomfortable. Because serious ankle and other injuries can result if comfort is favored over support, proper support in an in-line roller skate has been the dominant design criteria in the past.




As discussed briefly above, the conventional upper shoe portion of the in-line roller skate is usually formed of rigid, non-breathable, plastic materials having an inner liner. The plastic material generally forms the outer structure of the upper shoe portion, thereby requiring that a soft inner liner of sponge rubber or other like material be included to provide comfort to the user. Since such soft materials combined with the rigid plastic shell are good insulators and do not readily transmit heat or air away from the user's foot, the result is a hot upper shoe portion.




To provide lateral stability, conventional alpine ski boot designs have readily been adapted to in-line roller skates. These boots provide support and durability, characteristics necessary for in-line roller skates. U.S. Pat. Nos. 4,351,537 and 5,171,033 are both exemplary of rigid injection molded boots adapted to winter sports, such as ice skating and alpine skiing, which have been modified for in-line roller skating applications. These patents disclose an upper boot portion that comprises a hard plastic outer shell with a soft inner liner. While this type of boot design is well-suited for cold weather sports, the upper shoe portion tends to be hot and uncomfortable when used in warm weather sports such as in-line roller skating. The '033 patent suggests that by including “primarily unobstructed ventilation ports” in the rigid synthetic outer shell of the upper shoe portion, air can circulate around the skater's foot, thereby eliminating some of the heat associated with the hard plastic outer shell. While this patent seeks to address the issue of comfort, the disclosed upper shoe portion is still configured of two parts, including a hard plastic outer shell and a soft inner liner, which in warm weather conditions can be uncomfortable, compared to conventional walking and/or running shoes due to excessive heat buildup. The result is that the skater's feet are often hot, damp, and uncomfortable.




Another problem with the adoption of injection molded ski-type boots to in-line roller skating is that while providing excellent lateral stiffness and rigidity for lateral ankle support, these boots also create unnecessary and unwanted forward/rearward stiffness and rigidity. Ski-type boots detract from the performance characteristics of the skate because they limit the range of motion of the skater's legs and feet and therefore, the ability of the skater to utilize the full extent of his strength and agility.




Further, it is desirable for an in-line roller skate upper shoe portion to be lightweight. Boots that are well-suited to skiing applications wherein it is not necessary to raise and lower the boot with every movement of the foot (because the skier relies on gravity to provide the forward or downward motion) prove heavy and bulky when adapted to in-line roller skating. When skating on a flat surface, the in-line roller skater must lift the boot with every stride to provide a forward impetus, and a heavy upper shoe portion causes fatigue and reduces skating enjoyment.




Alternative modes of providing both comfort and adequate support for in-line roller skating have been suggested. Specifically, U.S. Pat. Nos. 3,963,252, 4,418,929, and 5,069,462 show roller skate frames that include a platform adapted to allow the skater to wear a conventional street shoe that is inserted into a series of braces and supports. These skates offer alternative shoe and frame designs to the rigid plastic outer shell and inner liner of the conventional in-line roller skate.




However, significant problems exist with such designs in that the adjustable braces and supports of these designs, while needed to accommodate numerous shoe sizes and shapes, are bulky and uncomfortable. Additionally, there is a limited range of shoe types that the skates will accommodate, and thus, there is the additional requirement that the skater have the proper shoe type to properly utilize the skate.




The outer plastic shells of previous in-line roller skates have created difficulty in styling the skates such as has been done with hiking boots and other footwear that have not had rigid outer shells. However, the rigid outer shells have thought to be necessary to provide adequate medial and lateral support while allowing ease of fore and aft movement of the leg of the skater relative to the skater's foot during skating. A recreational skater may not have the required strength and ability to utilize a low-cut skate which provides ease of movement. The skate would not provide enough lateral and medial support. Skates that do provide lateral and medial support and that do not include the rigid plastic outer shell construction include hockey skates. Hockey skates do provide adequate, lateral and medial support for the skater's ankle. However, fore and aft movement of the lower leg of the skater relative to the skater's foot is also limited. The hockey skate uppers are generally quite rigid and unforgiving. Therefore, a need exists to provide a skate that includes an upper structural support member for medial and lateral support while providing for ease of fore and aft movement without totally encompassing the skaters foot in a rigid plastic shell.




SUMMARY OF THE INVENTION




In accordance with the present invention a skate for receiving a foot of a skater is disclosed. The skate includes a frame, a rigid base, a substantially non-rigid upper portion, and a substantially rigid upper portion. The frame has a means for riding on a surface. The rigid base is securely attached to the frame. The base is adapted to support the bottom of the skater's foot and includes a heel portion and a toe portion adapted to support the areas beneath the heel, ball, and toes of the skater's foot. The substantially non-rigid upper portion is adapted to receive the skater's foot. It substantially covers the top and ankle of the skater's foot and is permanently affixed to the rigid base. The substantially rigid upper portion is coupled to the non-rigid upper portion and to the rigid base. The rigid upper portion includes an ankle support cuff extending above the skater's ankle when wearing the skate. The rigid upper portion is adjacent only portions of the non-rigid upper portion, leaving a substantial portion of the vamp of the skate without rigid support directly adjacent thereto. The non-rigid upper portion extends to above the cuff.




In the preferred embodiment of the invention the substantially non-rigid upper portion includes an outer shell. The ankle support cuff is disposed beneath the outer shell. In one aspect of the invention the substantially non-rigid upper portion also includes billows in a front portion and a rear portion of the ankle area of the upper portion. The billows are adapted to allow flexible movement of the substantially non-rigid upper portion.




In another preferred aspect of the invention the substantially rigid upper portion further includes an internal heel counter beneath the outer shell. The ankle support cuff is pivotally connected to the internal heel counter. An external heel counter may also extend upwardly from the base around the heel portion of the upper portion on the outside of the outer shell.




In one embodiment of the invention the internal heel counter and the ankle support cuff are pivotally interconnected with a reduced section of heel counter material, the heel counter and ankle support cuff being integrally formed.




In the preferred embodiment of the invention the heel counter includes two sides with recesses along the inner portion of the tops thereof. The ankle support cuff includes lower edges disposed at least partially within the recesses. Preferably, the recesses include grooves extending downwardly therein. The cuff includes downwardly projecting tongues on either side thereof disposed within the grooves. The recesses in the sides of the heel counter are preferably arcuate in shape and complementary arcuately shaped tongues exist on the sides of the cuff. The recesses are preferably disposed on the inner sides of the heel counter with the lower portion of the cuff overlapping the heel counter on the inner sides thereof.




A further aspect of the preferred embodiment of the invention includes substantially rigid support panels disposed on the sides of the interface between the heel counter and the ankle support cuff. The support panels are fixed to the heel counter such that the ankle support cuff is movable relative to the panels.




One aspect of an alternate embodiment of the invention includes arcuate slots within the arcuate portions of the heel counter. In this embodiment, the cuff further includes pins through the bottom arcuate portions thereof. The pins extend through the slots in the heel counter.




In another alternate embodiment of the invention the arcuate portions of the heel counter and the arcuate portions of the cuff are interconnected with arms attached therebetween. These arcuate portions of the heel counter preferably include recesses for receiving the arcuate portions of the cuff.




The preferred embodiment of the invention may also be described as a skate for receiving a foot of the skater that includes a frame, a rigid base, an external heel counter, an upper having an outer shell, a substantially rigid internal heel counter, and a substantially rigid ankle support cuff. The frame has wheels or a blade for riding on a surface. The rigid base is securely attached to the frame. The external heel counter extends upwardly from the base around the heel portion of the skate. The outer shell is constructed of substantially soft pliable material. The internal heel counter is disposed beneath the outer shell and extends around the heel area of the skate above the top of the external heel counter. The ankle support cuff is pivotally coupled to the internal heel counter and disposed beneath the outer shell. Preferably, the internal heel counter also includes at least one groove along at least a portion thereof for receiving the lower edge of the cuff in substantially sliding engagement therewith.




The above-described skate construction provides a skate that has great aesthetic appeal without substantial plastic material on the external body of the skate. The skate also provides superior lateral and medial support while allowing fore and aft movement of the lower leg of the skater relative to the skater's foot, with the cuff being pivotally secured within the upper.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 1

, an in-line roller skate


10


made according to the present invention is disclosed. In-line skate


10


includes an upper


12


connected to a frame


14


, which secures wheels


16


. Upper


12


includes a rigid base


18


for interconnection to frame


14


. Preferably, rigid base


18


extends beneath upper


12


substantially from heel to toe. An external heel counter


20


is preferably integrally formed with base


18


. Alternatively, external heel counter


20


could be omitted or formed separately, unattached to base


18


. A toe cap


22


is also separately formed and attached to base


18


to protect the toe end of the skate from scuffs and wear. A toe cap


22


also protects the skater's foot from impacts with hard surfaces.




Most of the rest of upper


12


is constructed of soft, breathable, pliable material of the type commonly used in shoes or hiking boots. Thus, synthetic or natural leathers and meshes or other fabrics may be used to construct the soft portions of upper


12


. These portions include a fore foot portion


24


generally below the ankle area of the skate and an ankle portion


26


at and above the ankle portion of the skate. Laces


28


are preferably used to secure upper


12


tightly around the foot of the skater in a conventional fashion. However, buckles, straps, Velcro™, or other fasteners may alternatively be used. In the preferred embodiment of the invention forward bellows


32


and aft billows


30


are secured within cutout portions of upper


12


just over the heel and between the ankle and fore foot portions


26


and


24


of upper


12


. Forward and aft bellows


32


and


30


allow ease of flexing of ankle portion


26


relative to fore foot portion


24


.




Much of the construction of the upper of the skate is similar to that disclosed in U.S. Pat. No. 5,437,466 incorporated herein by reference. The skate disclosed in the parent application (U.S. Pat. No. 5,437,466) includes a soft pliable upper. The upper disclosed in the '466 patent provides medial and lateral support as well as fore and aft flexibility with a rigid external heel counter pivotally interconnected with a rigid external cuff. The same concept is employed in the present invention. However, the present application provides further details and constructions with a rigid heel counter and cuff placed inside the relatively soft outer shell


44


of upper


12


. An internal heel counter


34


is preferably attached to base


18


by connection to an outer shell


44


and a last board


52


(illustrated in FIG.


3


). Internal heel counter


34


rises from base


18


beginning at approximately the middle of the sides of base


18


upwardly toward ankle portion


26


of upper


12


. Internal heel counter


34


then gradually descends to a position below aft billows


30


at the rear of the heel portion of upper


12


and above external heel counter


20


. Thus, internal heel counter


34


is cantilevered upwardly from external heel counter


20


except that it has outer shell


44


placed therebetween in the preferred embodiment.





FIG. 2

further illustrates the heel counter/internal cuff construction. The right and left sides of internal heel counter


34


are substantially the same except for variations due to differences in the anatomical shapes and movements between the medial and lateral sides of the skater's feet. The uppermost portion of both sides of internal heel counter


34


includes recesses with arcuate lower boundaries. The bottom of the recesses preferably includes grooves


40


into which an ankle cuff


36


is engaged with a tongue and groove configuration. Pivot pins


38


are secured at the radial centers of the arcuate portions and extend between ankle cuff


36


and internal heel counter


34


. Preferably pivot pins


38


are rivets. Pivot pins


38


allow fore and aft movement of ankle cuff


36


relative to internal heel counter


34


. Pivot pins


38


restrict lateral and medial flex of ankle cuff


36


. Ankle cuff


36


is constructed of a rigid material such as plastic or fiber-reinforced plastic. The material is rigid relative to the softer portions of upper


12


that surround most of the rest of the foot of the skater. Ankle cuff


36


is preferably U-shaped as viewed from above such that it surrounds the lower leg of the skater and ankle of the skater from behind toward the front of the skate. Ankle cuff


36


preferably does not entirely surround the ankle or lower leg of the skater but preferably extends in front of the ankle bones. Thus, ankle cuff


36


provides medial and lateral support to the skater's ankle while allowing fore and aft flex about pivot pin


38


. Ankle portion


26


of upper


12


is able to flex fore and aft with ankle cuff


36


since it is secured therearound and is of a softer, more flexible material than ankle cuff


36


. Thereby, with the above described construction, a skate is provided that has the pleasing aesthetic appearance of a sport shoe or hiking boot with superior medial and lateral support and fore and aft flexibility that are required for in-line skating.




The arrangement of pivot pin


38


and groove


40


with a cuff tongue


42


(as illustrated in

FIGS. 3 and 4

) provides a strong and supportive interconnection between ankle cuff


36


and internal heel counter


34


. Both medial and lateral flex are restricted by both sides of ankle cuff


36


with this arrangement since there is a vertical space between pivot pin


38


and the tongue and groove arrangement.





FIG. 3

further illustrates the details of the layering of upper


12


. As discussed above, a cuff tongue


42


extends downwardly from cuff


36


to interface with groove


40


of heel counter


34


. Thus, a sliding arrangement exists between cuff


36


and heel counter


34


at the interface between the two with a semi-circular tongue and groove interface. The portion of internal heel counter


34


that extends above pivot pin


38


is preferably on the outside of ankle cuff


36


to provide additional support when any portion of cuff


36


is pushed outwardly in a medial or lateral direction.




As seen in

FIGS. 3 and 4

, upper


12


includes the outer shell


44


mentioned above substantially encompassing the majority of upper


12


. Outer layer or shell


44


is preferably constructed of a leather or flexible man-made materials. Outer shell


44


is secured to base


18


, toe cap


22


, and external heel counter


20


. Outer shell


44


extends to the top of upper


12


where it is preferably joined to an inner lining


46


. Inner lining


46


lines the interior walls of upper


12


. Inner lining


46


is preferably a breathable material such as a tricot or other conventional breathable lining. A soft padding


48


is secured between inner lining


46


and ankle cuff and internal heel counter


36


and


34


. Padding


48


also preferably extends between inner lining


46


and outer shell


44


in areas that do not include heel counter


34


and cuff


36


. Padding


48


is preferably a conventional padding such as an open cell foam material.





FIG. 3

also illustrates skate tongue


50


extending in a conventional manner in front portion of upper


12


.




A last board


52


permanently secures the above-described portions of upper


12


to base


18


. Preferably, rivets or other fasteners extend through frame


14


, base


18


and last board


52


. Adhesives are also used. Outer shell


44


as well as internal heel counter


34


extend at least partially beneath last board


52


to be sandwiched securely between last board


52


and base


18


. The secure connection of upper


12


to base


18


provides a skate that is superior in performance to any skates that include removable liners since the foot of the skater can be more securely held within the skate and to the base and frame. An insole


54


is placed over last board


52


within skate upper


12


.




Turning now to FIGS.


5


-


13


, alternate embodiments of the invention will now be discussed. In the figures most details of the uppers are not illustrated to more clearly depict the arrangement of the cuffs and heel counters. Also note that the last two digits of each numbered element correspond to like-numbered elements in previous embodiments.





FIG. 5

illustrates an alternate embodiment of the present invention. Note that like reference numbers are used throughout

FIG. 5

except that the number


100


has been added to each. Internal heel counter


134


is connected to internal cuff


136


by a pivot neck


138


. Pivot neck


138


is small enough so as to create a “live hinge” between cuff


136


and heel counter


134


. In this embodiment, cuff


136


may either be in the form of side panels within the sides of upper


112


or may extend around the back of the skate in a generally U-shaped configuration. The details of most of upper


112


are not illustrated in

FIG. 5

so as to more clearly represent internal heel counter


134


, pivot neck


138


, and internal cuff


136


. The remaining details are similar to those disclosed above in connection with

FIGS. 1 through 4

. Movement of internal cuff


136


is also shown in phantom lines in FIG.


5


. With cuff


136


having a U-shaped configuration, the structural integrity to provide medial and lateral support to the ankle of the skater is provided in a simple, low-cost, integral construction with internal heel counter


134


while fore and aft pivoting motion is still allowed.




Referring now to

FIG. 6

, an embodiment of the present invention with an internal cuff


236


interfacing with an internal heel counter


234


does not include a pivot pin at the center of the radius of curvature of the interface. In this embodiment, internal cuff


236


is interconnected with internal heel counter


234


by a tongue and groove arrangement as discussed above. However, forward and rearward arms


258


and


260


bias cuff


236


to a neutral position and hold cuff


236


within groove


240


. Forward and rearward arms


258


and


260


form a V-shape with the bottoms of the arms being connected to a heel counter pin secured between the arms and internal heel counter


234


beneath the lowest portion of groove


240


. Alternatively, groove


240


may simply be a recess on the sides of internal heel counter


234


. The upper ends of arms


258


and


260


are secured to guide holes


262


within heel counter


234


by guide pins


264


. Guide pins


264


slide within arcuate guide holes


262


and hold the sides of cuff


236


against heel counter


234


. Arms


258


and


260


may be on the interior or exterior of internal heel counter


234


. Arms


258


and


260


are preferably constructed from a tough elastomeric material. The remaining details of the embodiment illustrated in

FIG. 6

are similar to the embodiments discussed above.




Referring now to

FIG. 7

, another alternate embodiment similar to that of

FIG. 6

will be described. In this embodiment, a single elastomeric arm


358


is fixedly secured on both ends in a horizontal fashion to internal heel counter


334


. Arm


358


is secured across the lower portion of the recess in internal heel counter


334


with the lowermost part of cuff


336


disposed between arm


358


and heel counter


334


. Arm


358


is elastic in nature and flexible to permit fore and aft movement of cuff


336


relative to internal heel counter


334


. Depending on the elasticity of arm


358


, the lower arcuate edge of heel counter


336


may rocker inside the recess created within the top of heel counter


334


, thus pulling somewhat upwardly with guide pin


364


on arm


358


. The recess within the top of heel counter


334


may have a greater radius of curvature so as to permit such rocketing.




Another embodiment will now be discussed in connection with FIG.


8


. This embodiment is similar to that of

FIGS. 6 and 7

discussed above. In this embodiment a flex cross


438


is interconnected between cuff


436


and internal heel counter


434


. The upper arm


462


of flex cross


438


is secured to cuff


436


, although alternatively, multiple arms may be connected to cuff


436


with one or more multiple arms connected to internal heel counter


434


. Again, cuff arm


462


and heel counter


458


are connected at their ends to cuff


436


and heel counter


434


, respectively. Thus, the elastic nature of flex cross


438


allows movement of cuff


436


relative to heel counter


434


with either rockering or pivoting sliding action between the arcuate portions of each.




Referring now to

FIG. 9

, another alternate embodiment, includes reversed arcuate portions of the heel counter


534


and cuff


536


such that cuff


536


includes a concave portion while heel counter


534


contains convex portions. In this case, heel counter


534


may extend upwardly to just above the ankle bones of the skater. Cuff


536


permits movement of the lower leg of the skater relative to internal heel counter


534


. Either a recess or a groove


540


with a cuff tongue


542


interfaces between the two elements.




Referring now to

FIG. 10

, an embodiment is shown wherein no positive pivotal or linkage connection is created between a cuff


636


and a heel counter


634


other than a tongue and recess or tongue and groove arrangement. The fact that cuff


636


and internal heel counter


634


are held within outer shell


44


of upper


612


provides enough retention of the elements such that no rivet or other fastening means is necessary.





FIG. 11

illustrates another alternate embodiment of the invention wherein a recess


740


in the top of the internal heel counter


734


is provided to overlap cuff


736


. However, in this embodiment a guide hole


762


in the form of an elongate arcuate slot is provided in the bottom of cuff


736


adjacent a recessed portion


740


of internal heel counter


734


. A heel counter pin


756


extends through recess portion


740


and through guide hole


762


to restrict the movement of cuff


736


and provide additional strength thereto.




A slight rearrangement of this construction is shown in FIG.


12


. In

FIG. 12

the same guide pin/guide hole arrangement is utilized except that a groove


840


is provided in the bottom of the recess into which a cuff tongue


842


extends. In this embodiment, cuff


836


is further restricted and strengthened from medial and lateral movement since cuff tongue


842


cannot move laterally or medially but only slide within groove


840


. Note that the actual pivot axis of cuff


836


may be above heel counter pin


856


due to guide hole


862


being arcuate and providing room for movement. Thus, the pivot axis may be at the ankle bones (malleoli) of the skater without having a rivet or pin projecting inwardly at that same location.




Referring now to

FIG. 13

, an additional element will be described relating to the external portion of upper


912


. In this embodiment, full bellows


966


are provided between ankle portion


926


and four-foot portion


924


to allow the two portions as well as cuff


936


and internal heel counter


934


to move relative to each other. Bellows


966


is an elastic rubbery material that is easily flexible without breaking down. In this embodiment, full bellows


966


extends from the front of the boot down below the ankle bone to above the heel behind the ankle bone in an arcuate fashion. Bellows


966


would then extend around the rear of the skate to a substantially mirror configuration on the other side of the skate.




Referring to

FIG. 14

, additional support structures preferably added to the basic structure described above relative to

FIGS. 1 through 4

will now be discussed. In

FIG. 14

the entire soft portion of upper


12


has been removed to expose last board


1052


, internal heel counter


1034


, and internal cuff


1036


. The construction of these three elements and arrangement in

FIG. 14

is substantially similar to that discussed above with regard to

FIGS. 1 through 4

. However, outer supports


1068


and inner supports


1070


have also been added to provide a smooth transition between these elements and for greater support and comfort. Outer supports


1068


are constructed of a plastic material and overlay the cuff and heel counter intersection of the skate and extend slightly forwardly therefrom. This provides additional rigidity to the pivotal and tongue and groove arrangement of the support structure and wraps around the foot of the skater to provide additional support. Likewise, inner supports


1070


cover the intersection between cuff


1036


and heel counter


1034


on the inside of these elements and also cover the inside of pivot pin


1038


which may be a rivet or other fastener. Thus, inner supports


1070


not only provide additional structural support for the foot of the skater to help maintain the proper orientation of the in-line skate, but also provide smooth transition between the elements for maximum comfort. Supports


1068


and


1070


are fixedly secured to internal heel counter


1034


. Supports


1068


and


1070


are slidably secured to internal cuff


1036


such that they nest against cuff


1036


so as to not hinder the movement thereof in the fore and aft directions. However, supports


1068


and


1070


further strengthen cuff


1036


in the lateral and medial directions and provide further support around the foot of the skater beyond that provided by heel counter


1034


.




While the preferred embodiments of the invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. The basic concepts and constructions disclosed could be modified such as by placing them on the exterior of the skate on the outside of outer shell


44


or by changing the arrangement in any number of ways while still maintaining basic concepts of having the rigid cuff interconnected to the heel counter in a pivotal fashion.
