Definitions

  • the present invention relates to ski boots comprising a retention and release mechanism providing a safety feature for the prevention and mitigation of the severity of injuries to the anterior cruciate knee ligament. and to provide a safe biomechanically natural rearward articulation.
  • the shaft comprises, at the rear, a rocker which interacts with a stop which is integral with the lower part in order to lock the shaft in a position inclined forwards.
  • the rocker is held in inactive position upon opening of the uppermost buckle by means of a cable and a spring. Thus, the shaft does not come to be locked at the wrong moment during walking.
  • U.S. Patent No. 5,127,171 discloses a ski boot with a shell comprising a shaft in two parts, the rear part of which is connected, on the one hand, to the shell and, on the other hand, to the front part of the shaft by two pair of links.
  • the axis of the articulations on the rear part are situated, in the closed position of the boot, on one side and the other of the plane containing the axes of articulation on the shaft and the front part of the shaft. It is possible to open the shaft wide for putting the boot on, while having only a limited tilting backwards of the rear part.
  • the upper connection can be associated with a closing lever.
  • U.S. Patent No. 5,107,608 there is disclosed a ski boot for lessening the incidence of knee injuries which the boot is said to exert a forward directional force on the skier's leg.
  • a releasing means changes the rigid support position for the foot and the lower leg on application of a predetermined level of force by the boot on the wearer.
  • the disclosure in US-5,107,608 goes on to report that rearward pressure of the person's lower leg against the rear leg element of the boot can be sensed by force sensors producing electrical outputs by the use of piezoelectric material.
  • a mechanical latch assembly employing a tension spring 96 is disclosed, which is described as urging or maintaining the device in ski position, and when said tension is overcome, a release position is obtained as shown in FIG. 8.
  • U.S. Patent No. 5,283,964 discloses a boot device for front-to-back immobilization of the upper, which acts on an oscillating level capable of being supported against a stop on the shell base.
  • the device is constituted by a rectilinear-motion control mechanism incorporating an external control device of which an inner part actuates via a cam a sensing device associated with the oscillating lever so as to impart to the latter an angular rotating movement around its pin toward a locked or release position in relation to the stop formed on the shell base.
  • the present invention is designed to provide a ski boot that allows the potentially damaging posterior forces at the spoiler (or upper shaft) section of a ski boot to be absorbed or transduced.
  • the present invention also contains as its objective the development of a unique mechanism to affect cuff displacement and arrest when appropriate to create a more safe environment and enhanced safety to the user.
  • the present invention has as its object the preparation of a retention and release mechanism providing a safety feature in a ski boot design.
  • the present invention accommodates a range of lower leg angles from about 12 to 15 to about 0 to -3 degrees without causing ankle injury or discomfort.
  • Inherent in the design herein is the feature that the recovery is possible (via stance adjustment with respect to the contralateral leg, combined with the "stop" or limit of rearward movement, supporting the leg) and injury to the ankle is prevented via leg support and reduction of portions of the boot lower that would impinge upon the leg/ankle in rearward motion (plantar flexion).
  • the moment arm of the ski tail of the present invention is reduced with respect to the skiers' center of gravity thereby reducing forces to the knee while still providing posterior support of the leg and thereby permitting the skier to continue skiing until recovery or falling. In the case of falling, rearward contact with the snow over the ski tail requires less derangement and force loading of the knee joint.
  • the present invention provides the ability for the user to adjust and allow for movement into a walking position of about -12 to -15 degrees, by adjustment of the device herein at the boot lower section thereof.
  • the present invention can permit the knee flexion angle to be increased when rearward support is again offered by the boot again taking advantage of more equitable load sharing of fibers within the ACL. Specifically load concentrations are distributed from the posterior lateral fiber bundle to the anterior medial fibers.
  • the present invention comprises a ski boot which provides a mechanical retention and release mechanism providing means for mitigating injury to the anterior cruciate knee ligament when the skier exerts posterior loads, potentially injurious to the knee. to the boot shaft upper, said retention and release mechanism capable of positioning lower leg angles from about +12 to 15 degrees in said retention position, to about 0 to -3 degrees, in a release position.
  • the present invention comprises a retention and release mechanism comprising a plate 50 which is affixed to a ski boot upper shaft by a pair of fixation tabs to allow hinged fixation, a spring 52 mounted on a single hinge pin under compression to provide sufficient anterior force with respect to the ski boot to induce said upper and lower arm linkages to remain against the posterior element of the ski boot while skiing or to return said armatures to a stable position after release, said spring having insufficient force to prevent the armatures from moving posteriorly to an unstable configuration during release, an upper arm linkage 54 comprising a pair of hinge pin receiving holes for pivotal fixation to said plate 50 and a pair of receiving holes for pivotal fixation to a lower arm linkage 56 comprising a space 58 to permit tool access to adjustment screw 60 and an interference edge 62.
  • the interference edge 62 is in spatial relationship with a coacting interference edge 64 of lower arm linkage 56 such that linkage elements 56 and 54 revert from a stable (anterior coacting with the boot) to an unstable position (posterior) when a predetermined amount of spring 66 deflection/compression has occurred.
  • the lower arm linkage 56 contains interference edge 64 and a pair of receiving slots 68 to provide hinged fixation to upper arm linkage 54 and axial translation of 54 with respect to 56.
  • the spring compression cap 59 contains a pair of holes to hold a pair of short hinge pins that connect 54 and 56 and a central axial hole to permit access to spring 66.
  • the release tension adjustment screw 60 contains a capless head to prevent axial loading/interference of spring 66 yet with sufficient keyway interface to permit turning by a tool.
  • the head stays within the spring coils.
  • a square threaded compression nut comprising a threaded axially orientated receiving hole for adjustment screw 60 of sufficient width to prevent rotation during tension adjustment, also comprising a visual indicator of spring tension against a scale (not shown).
  • Adjustment screw thrust plate 70 comprises a central indentation strike point for adjustment screw 60 by which inferior spring force is transduced to 56 via tabs comprising a pair of holes for receiving a hinge pin rigidly affixing 70 to 56.
  • At 72 is a cam that supports the release and retention mechanism upon a spring load latch (not shown) whereby the cam can be urged (by means not shown) to pivot anteriorly a sufficient amount to disengage from supporting latch allowing inferior translation of the release and retention mechanism and posterior motion of the boot upper shaft to permit walking, ingress and egress.
  • a stirrup mounting bracket which comprises a pair of holes for fixation by screws to a stirrup (lower outer shell cuff element), a pair of holes for receiving a hinge pin and pivotal affixation of 72 and 74 to 70 and 56.
  • Furthermore 74 contains a strike plate coacting with 72 to prevent excessive posterior rotation of 72 providing a stable support configuration until 72 is urged forward to assume a "walk" mode.
  • FIG. 6 is an assembled illustration of the release and retention mechanism of FIG. 5. Shown again in assembled form are the plate 50, the upper arm linkage 54, interference edge 62, which can also be termed a superior interference contact edge, interference edge 64, which can also be termed an inferior contact edge, lower arm linkage 56, stirrup mounting bracket 74 and cam 72. Also illustrated in FIG. 5 are the adjustment screw thrust plate 70 and square threaded compression nut 69. Finally, FIG. 5 also shows at 74 the stirrup mounting bracket, at 76 the visual tension indicator, at 80 the hinge pin head, at 82 the short hinge pin head, at 84 the head of the single hinge pin, and at 86 the rivet mounting hole of plate 50. Finally, at 88 is illustrated a hinge pin head, and at 90 is shown the flange of 56 that acts to a shoulder to augment the travel limit of spring cap (internal, not shown) against the top of the slot.
  • interference edge 62 which can also be termed a superior interference contact edge
  • interference edge 64 which can also be terme
  • FIG. 7 illustrates in further cross-sectional view the release and retention mechanism, in the ski position, more clearly showing the placement of spring 52.
  • the front of the boot is to the left hand side of the release and retention mechanism shown in FIG. 7.
  • FIG. 8 illustrates the release and retention mechanism is release position. Also shown in FIG. 8 at 92 is the contact which occurs as between lower arm linkage and stirrup mounting bracket 74 which further serves to limit travel of the upper arm linkage 54.
  • FIG. 9 illustrates at 94 the cutout section of the boot in the stirrup cuff element for placement of the release and retention device herein, at 96 the stirrup pivot point which rivets to the lower shell of the boot, and finally, at 98, one of the screw hole pairs for mounting the stirrup mounting bracket 74.
  • FIGS. 10-12 best illustrate in cross-sectional form the release and retention mechanism in both retention and release positions.
  • the lower arm linkage 56 is urged against the upper shaft 100 of the boot.
  • shown at 102 is the space or opening as between upper arm linkage 54 and lower arm linkage 56.
  • slot 68 reveals in FIG. 10 that when in the ski position, the short hinge pin head 82 is positioned at the top of the slot 68, due to spring 66 counter force or extension force.
  • the skier would lean back on the release and retention mechanism, and load transfer would occur through the mechanism to the bottom of said mechanism, as more particularly illustrated in FIG. 11.
  • FIG. 11 As can be seen in FIG.
  • FIG. 13 illustrates the ski position, and note therein the stable relationships of the arm linkages and cam 72 on the latch 73.
  • FIG. 14 shows cam 72 being switched by a manual interface (not shown) thereby causing an unstable relationship between cam 72 and the latch 73.
  • FIG. 15 shows both boot upper shaft (cuff element) 106 and boot stirrup (lower shaft/cuff element) 108 rotating posteriorly on their respective axis to permit a normal walking gait or to facilitate egress or gress, as a result of manual switching.
  • FIG. 16 illustrates the relationship of the arm linkages and the boot upper shaft 106 and boot stirrup 108 in the ACL release position. As illustrated therein, the release and retention mechanism when releases provides a substantially vertical position to the skier.
  • the present invention therefore relates to a latch element for a retention and release mechanism in a ski boot.
  • a latch element for a retention and release mechanism in a ski boot.
  • said cam being positioned in such a manner that posterior forces imparted by a user urges said cam to disengage from said stop at a predetermined level of posterior force.
  • the present invention can also be described as a ski boot containing a retention and release mechanism providing restriction to posterior movement of the upper shaft of said boot and allowing posterior travel of said shaft after a predetermined level of force has been obtained, comprising a latch which contains a plurality of elements that permits compression and change of length when subjected to rearward force by the upper shaft of said boot.
  • the present invention relates to a retention and release mechanism formed by a cam that coacts with a stop, said cam being positioned in a manner such that posterior forces imparted to the wearers leg, urges said cam to override or disengage from said stop(s) until the magnitude of force is sufficient to cause the cam to disengage or fully overrun said stop(s) at a predetermined and adjustable level of force.
  • the invention also relates to a device to a release and retention mechanism having an adjustable element that controls the amount of force required to displace a cam to a degree that it fully overrides its coacting stop(s).
  • This device comprises a spring or an elastic element and a release mechanism such as a cam or ball spring and socket the exact configuration of which can be various and apparent to those skilled in the art of load specific release mechanisms such as ski bindings and the like.
  • the invention also relates to a release and retention mechanism offering a secondary elastic function providing sufficient resistance to rearward displacement of the boot shaft to enable the wearer to maintain control of the ski.
  • This arrest feature limits the posterior displacement of the boot shaft after the "rear breakout" or release has occurred.
  • An important feature of the present invention is that release or break out is limited. This function can be obtained by the interference of the boot upper with the lower, or by means of a dash pot or stop(s) that coacts with the one or more parts of the primary retention and release mechanism or another portion of the boot upper shaft.
  • the secondary "stop” or arrest mechanism should limit posterior travel of the shaft to less than approximately 20 degrees rearward from vertical.
  • the invention also relates to a release and retention mechanism that can be configured to offer a staged release that facilitates repeated compression/deflection of an elastic element, and resetting of a latch mechanism into a series of stop elements or likewise by a series of latch elements coacting with the stop.
  • the invention also relates to a retention and release mechanism offering sufficient rearward displacement of the boot shaft to increase the tendency of the knee joint of the wearer to extend to a degree that reduces the likelihood that injury to the anterior cruciate ligament of the knee will occur.
  • the invention provides the function of absorbing potentially injurious forces before said forces are sustained by the wearer's knee joint.
  • An elastic element comprising a means of adjusting preload, acts as a means to urge the interface constraining the boot shaft posteriorly to disengage affecting a posterior "release" to the arrest position. The adjustment governs the level of force or load required to affect release.
  • the invention relates to a ski boot having high rearward upper shaft resistance to flex to provide typical performance found in contemporary ski boots until a rearward force approaching that sufficient to damage the knee is encountered whereby the release and retention mechanism will allow the upper boot shaft to freely rotate rearwards for a small distance sufficient to protect the knee yet enable the skier to maintain control of the ski in a new position until the skier can resume a normal forward skiing posture at which point the retention feature of the invention will engage and support the leg posteriorly until the same potentially injurious posterior force level is again encountered.
  • the effective moment arm of the ski tail to the knee being shortened increases the likelihood that the skier will fall over the tail of his ski without damaging knee ligaments.
  • the present invention describes a ski boot comprising at least one lower foot and heel holding portion with a shaft, in the form of a collar. articulated on the lower part, and comprising connecting means consisting of a latch which interacts with a stop which is integral with the lower part, said connecting means comprising means for fixing or releasing said shaft for rotation relative to the lower part consisting of a cable provided with at least one closing buckle for manually disconnecting said fixation means by pivoting all or a portion of the latch to disengage it from the stop to facilitate upright standing and walking with the boot.
  • means for automatically disconnecting said latch when an anticipated dangerous level of force is applied to the rear of the shaft by the wearer's leg that comprises an elastic element, a proximal housing which is affixed to the upper shaft, and a distal housing element that is constrained by the proximal housing element in all axis except in compression of the elastic element, a distal element that coacts with the stops that is mobile along the compression axis of the elastic element and is disengaged from said stop when sufficient displacement of the elastic element allows an armature that is pivotally affixed to said to the proximal housing element collide with the stop interface element connected to the distal housing element that via eccentric coaction to its compression axis urges the latch assembly to disengage from the stop.
  • the present invention discloses a ski boot having a pivotally mobile upper shaft, and a lower foot and heel holding portion, that comprises a stop and coacting latch sensing mechanism to allow the upper shaft to further articulate in the rearward direction relative to the Lower foot and heel holding portion under the condition of a force applied to said stop and coacting latch mechanism which urges the latch to disengage from said stop.
  • said sensing mechanism preferably comprises a spring and an axially slidable mobile element that coacts with a cam member positioned within said latch that urges a pivotally mobile latch element to cause the latch to disengage from the stop.
  • the present invention contemplates the above described retention and release mechanism in a ski boot consisting of a shell surrounding the foot and heel and of a shaft consisting of a front part and of a rear part capable of being tilted towards the rear in order to free the foot and to allow the boot to be put on and off, in which the rear part of the shaft can form a translation movement in addition to a rotation movement, wherein the rear part of the shaft is connected in its lower part to the shell by first means of connection forming axis of articulation with the shell and rear part of the shaft, respectively, which allows a rotation and translation of said rear part in relation to an axis which is defined and fixed in relation to the shell and said upper part of the shaft is connected at another point by a second means of connection, forming an axis of articulation with the front part and rear part of the shaft, respectively, which allows a rotation and translation of said rear part in relation to an axis which is defined and fixed in relation to the front part, the axis of articulation for
