Abstract

PURPOSE: To prevent a skier from hazard at the time of tumbling by dividing up and down a rear spoiler of a ski boot consisting of a bottom shell, front cuff, and rear spoiler, coupling the lower part to the bottom shell together with the front cuff, coupling together the upper and lower parts resiliently using a spring, and making it possible to open the rear spoiler to the back. CONSTITUTION: A ski boot is composed of a bottom shell 1, front cuff 2, and tear spoiler 3, wherein the spoiler 3 is divided into the upper part 5 and lower part 4. In the pivot position 6, the lower part 4 is mounted rotatably on both sides of the bottom shell 1 together with the front cuff 2. The upper part 5 and lower part 4 are coupled together by a pivot pin 7, and the two ends of a compression coil spring 8 are fixed to the upper and lower parts 5 and 4 so that a resilient coupling is established. From the front cuff 2 a tightening cable 9 is set over to a tension lever where a small eccentric roll 13 is interposed. When the skier is tumbled, the rear spoiler is opened to the back to prevent his leg from a torsional deformity.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates generally to athletic footwear, and more particularly to the construction of ski boots. In a more detailed aspect of the present invention, a ski boot of the present invention has a bottom shell, i.e., a lower shell, and a multi-part upper, i.e., multi-part shaft, the multi-part shaft having a front cuff, i.e. , A shaft portion and a rear spoiler, i.e., a shaft portion, the rear spoiler being rotatably supported on the bottom shell or the front cuff for the purpose of closing the multi-part upper part, i.e. the multi-part shaft, It is connected to the bottom shell or the front cuff by closing means.

Generally speaking, the ski boot of the present invention is also of the type having a bottom shell, a front cuff, and a rear spoiler mounted on the bottom shell, the rear spoiler being provided with closure means. Connected with the front cuff.

[0003]

BACKGROUND OF THE INVENTION Ski boot constructions known to date generally include a relatively rigid lower shell member, a front cuff or tongue portion, and a rear spoiler or rear shaft portion. And the rear shaft part has
It is rotatably supported by the lower shell member or the front cuff depending on the circumstances. Both shaft parts, i.e.
The front cuff and rear spoiler surround, or wrap, the lower leg of the skier. About 20 years ago, ski boots were low, relatively flexible, and provided little support when leaning backwards. By the late 1970s, ski boots were tall, stiff, and had almost good support in backward leaning. As a result, the problem of leg damage that had previously occurred at the talar, or tibial, site has been replaced by injury at the knee site. In fact, one of the six medically significant injuries in Alpine skiing is 4
A severe knee sprain that affects one or more of the two large knee ligaments. Knee sprains and split ligaments in the knee (anterior and posterior cruciform, alternating medial and lateral) are serious injuries associated with skis that are difficult to treat, and thus medically, Health recovery techniques are not always successful. Failure to treat serious damage to the anterior cross ligament results in progressive deterioration of the knee cartilage (medial and lateral meniscus) and chronic articular condition. Therefore,
Efforts to develop modern ski boots were made, for example, in January 1991.
As disclosed in European Patent Application 0410136 published on 30th, it is specifically directed to providing a hardware solution that helps reduce the risk of causing severe knee injury.

The combination of torsional loads applied to the skier's knees, especially the front and rear crosses, occurs during a rearward fall or when attempting to avoid such a rearward fall. Furthermore, if the skier loses balance when jumping on the summit of a rounded mountain, the rear edge of the ski will first hit the ground, which will cause serious injuries when the lower leg of the skier accelerates forward and lands. Causes severe knee damage. The knee is secured in a fully extended position and the impact forces push the back of the boot against the back of the calf, thereby pushing the tibia out under the femur of the knee. For the coupling of the ski and the boot as is done by ski binding, for example, the leading jaw of the ski binding, i.e. the front fitting, detects the force directed towards the rear and releases this force openly. There is no modern design of open or trigger mechanism to respond.

[0005]

SUMMARY OF THE INVENTION Therefore, in light of the above,
The main object of the invention is, in particular, that the skier's extreme backward leaning, which is caused by the skier's normal failure or the impact of the trailing edge of the ski on landing following a jump,
It is an object of the present invention to provide a new and improved ski boot which is constructed so as not to lead to serious knee sprains or injury involving the ligaments of the knee. In other words, a ski boot constructed according to the invention allows the lower leg of the skier to bend backwards during a rearward fall, whereby the forward acceleration of the lower leg when the knee is bent. Brakes and dampens on the back side, substantially reducing the risk of serious knee injury.

Maintaining the above objects, another object of the present invention is to have an upper portion, namely a shaft, which opens during a dampening elastic movement of the shaft portion rearward,
It is an object of the present invention to provide an improved structure for a ski boot that loosens or releases the upper portion of the ski boot, ie, the lower leg of the skier gripped by the shaft.
Yet another object of the invention is a ski boot of the character described above, which comprises additional means to help prevent the wearer's foot from being inadvertently removed from such ski boot when the ski boot is opened. To provide a new and improved structure.

In order to carry out these objects of the invention and further objects which will become readily apparent as the description proceeds, a rear spoiler, especially with at least an upper part, serves to act the elastic restoring force means. It is possible to pivot dampingly in the opening direction against and to release the path damping effect of the closing means that connects the rear spoiler with the bottom shell or the front cuff, i.e. with force damping effect release to the open position backwards. The ski boot of this development is made clear by the feature that it can rotate.

The rear spoiler has a lower portion rotatably supported on the bottom shell and the above-mentioned upper portion supported on the lower portion by an axis extending transverse to the longitudinal axis of the ski boot. The upper portion of the rear spoiler can rotate rearward in the opening direction, independently of the lower portion, against the action of the elastic restoring force means described above.

In one embodiment, the elastic return force means comprises a pair of compression spring elements, each compression spring element extending along each shaft side and between an upper portion and a rear portion of the rear spoiler. The upper portion is configured to overlap with the lower portion, and the upper portion overlaps with the lower portion to allow backward movement. The closure means comprises a pull cable attached to the front cuff on both sides of the shaft, and a pull lever connected to the pull cable and rotatably mounted in the middle of the rear zone of the lower portion of the rear spoiler. To do.

The release means described above constitutes a release element projectingly arranged at the lower edge of the upper part of the rear spoiler. In order to release the rear spoiler to be tilted to the open position, in order to stop pulling the tension cable by rotating it from a position beyond the dead center, i.e. to loosen it, the tension lever is It is actuated during the rearward pivoting movement of the upper part against the force of the pair of compression spring elements.

Bearing means are provided in the back zone of the lower portion of the rear spoiler. An eccentric roll is rotatably arranged on such bearing means, and a pulling lever is mounted on the eccentric roll whose pivot shaft is rotatably arranged. The above-mentioned release element, which is configured in the form of a spar projecting from the lower edge of the upper part of the rear spoiler, causes the eccentric roll to rotate by its bearing means during the rearward pivoting movement of the upper part of the rear spoiler. Displacement of the pivot axis of the pulled lever causes the pull lever to move from a position beyond the dead center defined by the direction of the pull cable acting on the lower end of the pull lever to an open position.

In addition, a saddle-like pressure plate is advantageously arranged in the region of the instep of the ski boot, such pressure plate acting on the instep of the skier. The pressure plate is positioned in a saddle-like manner, has two sides with respect to the longitudinal axis of the ski boot and assumes a foot-holding position. A pulling mechanism is located in the back zone of the lower portion of the rear spoiler and is provided with a Bowden control cable, which is used to connect the pressure plate with a pulling mechanism that helps pull such cable. is there. Each bowden control cable is engaged at one end with a pulling mechanism and advances forward on each side of the bottom shell, with the front end secured to each side of the saddle-like pressure plate. Advantageously, the front end of the outer sheath of the Bowden control cable is rigidly fixed to the bottom shell, leaving the pressure plate in its foot-holding position when the rear spoiler is tilted rearward.

In another embodiment of a ski boot constructed according to the invention, the closure means comprises a pulling cable attached to the front cuff at the side of each shaft, the pulling cable being below the rear spoiler. Form a cable loop in the back zone of the part. A spring support is located in the back zone of the upper portion of the rear spoiler. The closure means further comprises a pulling lever, which is connected to the pulling cable described above and is pivotally mounted on the spring support. For the purpose of pulling the pulling cable, the pulling lever can be pivoted in the vertical plane on the rear side of the ski boot against the action of a spring supported by a spring support.

Further, a latch detent is pivotally mounted on the spring support and a detent shaft is rigidly located in the lower portion of the rear spoiler. In the closed position of the closing means, the latch detent is latched on a rigidly arranged detent shaft, the spring support abuts the upper part of the rear spoiler with the latching, the tension lever being more than the spring support. Take the position below the dead center. First, when the upper part of the rear spoiler makes a backward pivoting motion during the skier's rearward fall, the latch detent is forced out of its position of engagement with the detent shaft and the rear spoiler This allows you to lean further back freely. In this way, the position beyond the dead center of the pulling lever that pulls the pulling cable is interrupted by the pivoting movement of the spring support which is connected to the pulling lever. Further, the lower portion of the rear spoiler is tilted rearward to the open position.

In another exemplary embodiment of the present invention, a ski boot has a bottom shell and a multi-part upper or multi-part shaft, the multi-part shaft having a front cuff and a rear spoiler. The rear spoiler, the bottom shell,
Alternatively, it is of a type that is rotatably supported by the front cuff and is connected to the bottom shell or the front cuff by closing means for the purpose of closing the upper part, that is, the shaft. To carry out the object of the invention, the ski boot is characterized by the characteristic, in particular, that two compression springs, preferably pre-biased, are supported on the rear spoiler, the closure means having a pair of tension cables. Each compression spring extends on each side of the rear spoiler and has one end engaged with each tension cable. Deflection means are provided on the front cuff on either side of the ski boot, and a pivot shaft connecting the unsplit rear spoiler with the bottom shell is located at the rear end of the bottom shell. The closure means further comprises
With the tension lever located at the rear portion of the rear spoiler, two compression springs are operatively associated with the tension lever by the tension cable. Each tension cable is guided from each compression spring along each side and travels forward to each deflection means and rearwardly on the pivot axis to the tension lever. In the boot closed position of the rear spoiler, the pull lever is located beyond the dead center.

In yet another embodiment of a ski boot constructed according to the invention, the closure means is shortened by means of a pulling device arranged in the rear part of the two-part rear spoiler and being rolled up and unwound by the pulling device. And a pull band that can be lengthened or lengthened. The release means constitutes a release mechanism arranged on one side of the front cuff, the rear spoiler being connected to this release mechanism by a tension band, one end of the tension band on the other side of the front cuff. It is firmly arranged. The release mechanism has a spring element that acts in the closing direction of the rear spoiler, so that the other end of the tension band pulled in the boot closing position, i.e. the ski position, by the spring device acts in the closing direction of the rear spoiler. It is held by the force of the spring element. Advantageously, the release mechanism further comprises a spring-biased locking lever, which is provided with a Bowden control cable for connecting the locking lever with a pulling device arranged on the rear part of the rear spoiler. Has a clutch to keep the tension band rolled up under tension. The above-mentioned spring element acting in the closing direction of the rear spoiler is compressed by the rearward movement of the rear spoiler in the releasing direction, releasing the rear spoiler following a constant spring bias movement,
The bowden cable is actuated by the release of a spring biased locking lever to disengage the clutch for the purpose of pivoting it to the open position.

In the ski boot of this embodiment, it is advantageous to place the saddle-like pressure plate in the instep region of the boat. The pressure plate has two sides with respect to the longitudinal axis of the boot and assumes a predetermined foot holding position. The pulling means is located on the rear portion of the rear spoiler and is provided with a Bowden cable or wire for connecting the compression plate with the pulling means, the pulling means serving to pull the Bowden cable or wire. Each bowden cable or wire is engaged at one end with a pulling means and guided from such pulling means to each side of the bottom shell, the front end of the cable or wire being attached to each side of the saddle-like compression plate. It is fixed.
The forward end of the bowden cable or the outer sheath of the wire is rigidly secured to the bottom shell so that the saddle-like pressure plate remains substantially in its foot-holding position when the rear spoiler is tilted rearward.

In yet another embodiment, the closure means comprises a pair of tension cables fixed to the rear spoiler on the sides of each shaft and a tension closure located in the instep region of the boot and actuated by rotation. .. Each pulling cable on the side of each shaft of the rear spoiler is guided forward by each deflecting means and moves in the longitudinal direction of the boot against the force of the spring element which dampeningly counteracts the impact force acting on the rear spoiler. It is connected to a tension closure which is displaceably mounted. The spring element is provided with force adjusting means and is operatively associated with the tension closing body, which subsequently releases the tension cable to move the adjustable spring bias, whereby the rear spoiler is opened. Is rotated to a predetermined open position.

In addition, the pull closure has a chassis arranged in the bottom shell, the chassis being provided with a rotatable drum housing for accommodating a rotating drum, which is rotatably mounted for winding up and rewinding a pair of tension cables. It is arranged. The spring element constitutes a compression spring supported between the rotary drum housing and the chassis, the rotary drum housing being displaceably arranged such that it can move longitudinally against the force of the compression spring. ing.
The rotary drum has a lower circumferential edge with locking knobs that serve to rotate the rotary drum and that has locking teeth that cooperate with lever-type catches rotatably mounted in the rotary drum housing. Serves to stop the rotation of the rotary knob and the rotary drum in the direction of rotation for rewinding the pull cable. Inclined stop means are provided on the chassis arranged on the bottom shell, by means of which the movement of a predetermined biasing force of the compression spring against the impact force acting on the rear spoiler in a damping manner is continued,
A lever-type catch of the displaceable rotary drum housing moves so as to abut the tilt-type stop means. as a result,
The lever-type catch is pivoted, thereby releasing the stopped rotating drum for the purpose of rewinding the pair of tension cables from the rotating drum. Thus, the rear spoiler can be rotated to the open position.

In addition, this embodiment advantageously has a saddle-like pressure distributor located in the Achilles tendon region of the ski boot. Such a pressure distributor may be a front cuff, or
It is positioned inwardly away from a rear spoiler mounted on a pivot shaft constituted by pivot means selectively provided on the bottom shell. A pair of spring elements each having an adjusting means are mounted in the upper region on each side of the rear spoiler. A pair of pull cables contact the outside of the pressure distributor or the rear part,
Push the pressure distributor forward when the multi-part shaft is closed. Each pull cable is engaged at one end with an associated spring element and each adjusting means serves to change the length of the pull cable. In addition, each pull cable
Proceeding downward from its associated spring element, the lower end of the cable hangs on the deflection point of the bottom shell and is fixed in the lowermost region of the rear spoiler, or, depending on the circumstances, on each of the above mentioned pivot axes of the rear spoiler. Fixed on the edge.
The pressure and foot-holding effect exerted by the pull cable is maximized when the rear spoiler is tilted forward in the closing direction so as to allow rearward deflection of the rear spoiler.

In one embodiment, the tension cables abutting the above-mentioned outer side of the saddle-shaped pressure distributor are arranged in a cross shape with respect to each other, and the tension cables from the associated spring elements are inclined on the outer side. And then advance downwards on each side. In a variant, the pulling cable, which abuts the outer side of the saddle-shaped pressure distributor, extends substantially in parallel from the associated spring element on the outer side and then advances downwards on each side of the rear spoiler. ..

In yet another exemplary embodiment of the present invention, a ski boot includes a longitudinal axis, a bottom shell, a front cuff, and
A rear spoiler rotatably supported on the bottom shell and connected to the front cuff by closure means. Now, in order to carry out the above-mentioned object of the invention, the ski boot of the invention comprises, inter alia, a rear spoiler having a slot in the lower region, the slot being located from one side of the rear spoiler to the opposite side. It is manifested by the feature of penetrating and extending rearwardly in a manner sloping upwards to the back zone and terminating at a distance on both sides from the lower edge of the rear spoiler. Pivot pins are positioned above the slots on the sides of both shafts and the rear spoiler is connected to the bottom shell by these pivot pins. Releasable locking devices are provided on both sides in the region of the slot ends located downwardly and forwardly, and a rear spoiler is retained on both shaft sides by the release locking devices on the bottom shell. There is. The rear spoiler has rim zones, or demarcation zones, located on opposite sides, the demarcation zones extending between the pivot pin and the locking device substantially parallel to the slots to form each flexible web. To do. These flexible webs bend outward under the action of a downwardly acting impact force on the rear spoiler and, as elastic members, dampen the rotational movement of the rear spoiler in the release direction.

Furthermore, the slots of the rear spoiler are provided with sliders, which are movable in the longitudinal direction, on both shaft side portions, respectively, to restrict the contraction of the slots to a certain degree depending on the position in the slots, and by such contraction. Deflection of each flexible web in the rim zone, ie the boundary zone, occurs on both shaft sides. The setting of the slider in the slot helps to set the hardness of the rear tilt damping, or, depending on the circumstances, the front cuff and the rear spoiler tilt forward to the boot closed position, which causes the flexible web to move accordingly. Helps set the hardness of the forward slope damping when bending in the opposite direction.

Finally, the ski boot of this embodiment has friction elements for the releasable locking means which serve to hold the rear spoiler in the closed or ski position. An eccentric detent pin is provided at the lower end of the rear zone of the rear spoiler so that each friction element is engaged at one end with each side of the eccentric detent pin. Further, each friction element advances forward on each side of the rear spoiler, the front end being secured to each releasable locking means. These locking means can be disengaged by actuating the eccentric detent pin in order to further pivot, ie tilt, the rear spoiler in the opening direction.

The invention will be better understood and objects other than those set forth above will become apparent upon consideration of the following detailed description. Referring to the accompanying drawings, to illustrate the same or similar parts throughout the various views of the drawings,
Approximately the same reference numerals and numbers are used.

[0026]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, in order to simplify the presentation of the drawings, the drawings shall include those necessary for those skilled in the art to understand the underlying principles and concepts of the present invention. It should be understood that the structure of the exemplary embodiment of ski boots formed in accordance with the present invention has been fully shown.

Attention is now directed, particularly to FIG. 1 of the drawings, by way of example, but not limitation, of the illustrated ski boot, in which the relatively rigid bottom shell or lower shell 1
And a front cuff or shaft portion or tongue 2 and a rear spoiler or shaft portion 3 which is understood to have a lower portion 4 and an upper portion 5. Will be done. The lower part 4 of the rear spoiler 3 is pivotally mounted together with the front cuff 2 in a pivot position 6 on both sides of the bottom shell, i.e. the lower shell 1, only one of the pivot positions 6 being shown in side view in FIG. Can be seen. The upper portion 5 of the rear spoiler 3 is rotatably attached to the lower portion 4 by a pivot pin or swivel pin 7. This upper part 5 overlaps at its lower edge with the upper edge of the lower part 4 and by overlapping the upper part 5 with the lower part 4 it is pivoted rearward into the position indicated by the broken line, ie the dotted line, i.e. , Can be tilted. This rotation, or tilt, in the opening direction is
This is done against the action of the compression coil springs 8 located on either side of the ski boot, only one of which is visible in the overall side view of the ski boot. These compression coil springs 8
Has one spring end supported by the lower part 4 and the other spring end by the upper part 5.

With this spring-damping system, the skier's shin, or lower leg, which attempts to avoid rearward fall or sitting during a panic stop, has its upper part 4
Elastically and dampening backwards, which substantially damps and dampens the forward acceleration of the rear lower leg with the knee flexed. The split construction of the posterior spoiler 3 avoids significant knee sprains involving one or more of the four critical knee ligaments, thus avoiding a possible sprain but an unbent upper part, ie , Much better than with a non-bending shaft,
Because of the flexible elasticity, i.e. the cushion support, the knee angle is again small, and furthermore, it is possible to be inserted by the support muscle action. Without a damping-elastic system, this muscular effect is 1
It is below the range of / 30 seconds, that is, the muscular action cannot be consciously maintained.

A pulling cable attached to both sides of the front cuff 2, that is, a tightening cable 9, communicates with a pulling lever 10 rotatably provided at a rear portion of the rear spoiler 3. Front cuff 2 and rear spoiler 3
The upper part of the boot consisting of, that is, the boot shaft,
It is closed by a closing means consisting of a pull cable, i.e. a tightening cable 9 and a pull lever 10.

These closing means are provided for the upper part 5 of the rear spoiler 3 when the upper part 5 is tilted rearward into the open position.
A spar 11 provided on the lower edge of the arm cooperates with the pulling lever 10 in such a way as to rotate the pulling lever 10 upward from the illustrated closed position, and by releasing the closing means the rear spoiler 3 opens the boot. Can be pivoted backwards into position.

FIG. 2 is a partially cut-away side view of FIG.
2 shows, on an enlarged scale, a detail of the ski boot according to FIG. 1, which detail shows an exemplary embodiment for the opening of the closure means. The pulling lever 10 is attached by means of its pivot shaft 12 to a small eccentric roll or a small eccentric roller 13, which roller 13 has a bearing 14 provided on the rear side of the lower part 4 of the rear spoiler 3. The pulling cable 9 engages at its lower part a pulling lever 10 and acts on it, so that the cable 9 is pulled to the position of the lever 10 shown in solid lines. The pull lever 10 is the lever 1
It is arranged at a position beyond the dead center that arises from the direction of the cable 9 in the region of the lever 10 with respect to the lever shaft 12 of 0. The eccentric roll or the eccentric roller 13 has a small lateral projecting portion 15 with which the spar 11 abuts the projecting portion 15 when the rear spoiler 3 is tilted rearward. In this way, the eccentric roll or the eccentric roller 13 is rotated, which causes the pivot shaft 12 of the lever 10 to move its position, as indicated by the dashed line in FIG.
Since it changes by moving inward with respect to, the dead center position of the pulling lever 10 becomes unstable,
The pulling lever 10 can be inadvertently snapped up in the position indicated by the dashed line. The pulling cable 9 is then no longer pulled and the entire rear spoiler 3 can be tilted, i.e. pivoted, rearward into the open position.

In a second exemplary embodiment of the ski boot constructed according to the invention and illustrated in FIG. 3, in the rear spoiler 3
Is likewise subdivided into a lower part 4 and an upper part 5. The lower part 4 is also rotatably supported by pivot pins 6 on both sides of the bottom shell, i.e. the lower shell 1, only one of the pins 6 being visible in the side view of FIG. The upper part 5 of the rear spoiler 3 is rotatably connected to the lower part 4 by means of a pivot shaft 17, which in this example is arranged very far behind.

The closure means is again formed by a pulling cable, ie a tightening cable 18, which is fastened at its ends to the front cuff 2. This cable 18 forms a cable loop 19 on the rear side of the lower part 4 of the rear spoiler 3,
9 is rigidly connected to the pulling lever 20. The pulling lever 20 has a spring carrier, that is, a lever shaft 21 provided on a spring housing 22.

A latch catch, that is, a detent 23 is rotatably supported on the upper end of the spring carrier, that is, the spring housing 22. This spring carrier 2
The compression coil spring 2 is provided between the upper end of 2 and the lever shaft 21.
4 is supported, and this compression spring 24
When 0 is placed in the lower position shown by the solid line in FIG. 3, it is pulled. In this lower position, the front cuff 2 and the rear spoiler 3 are connected to the pulling cable 18 in order to firmly enclose, ie wrap, the lower leg of the skier.
Pulled towards each other by. This causes the latch catch, ie the detent 23, of the spring carrier 22 to be firmly arranged in the lower part 4 of the rear spoiler 3. This is not particularly shown in FIGS. 3 and 4 for simplicity of illustration.

Now, when the skier falls backward, the upper part 5 of the rear spoiler 3 is masculinely dampened,
When tilted or pivoted rearward, the latch catch or detent 23 moves from its position of engagement with the detent shaft 25. In this way, the upper part 5 of the rear spoiler 3 is more freely pivoted rearward. When the boot upper part, that is, the boot shaft is closed, the tension lever 20 and the spring carrier 22 are
It is located in a position beyond the dead center according to FIG. Due to the rearward pivoting movement of the spring carrier 22, i.e. the tilting movement, the system consisting of the tension lever 20 and the spring carrier 22 can be moved from a position beyond the aforementioned dead center. As a result, the entire rear spoiler 3 can then be pivoted rearward to the open position. The cable 18 can be adjusted for different tensions, since the cable loop 19 can be attached to the pulling lever 20 in different positions by means of a screw-type adjuster provided on the pulling lever 20. Because. Thus, the release trigger points can be adjusted individually. In this second exemplary embodiment of a ski boot constructed according to the invention, the lower leg of the skier is gently braked rearward by a two-step opening movement.

According to the third exemplary embodiment of the invention shown in FIG. 5, the rear spoiler, ie the rear shaft portion 3, is not divided. Spring housings 29 are provided on both sides of the non-split rear spoiler 3, respectively, and compression springs 30 are respectively arranged in the housings 29. The springs 30 are biased in advance and are inclined forward and downward. It preferably extends. Only one of these spring housings 29 can be seen in the cutaway side view of FIG. The pre-biasing forces of these compression springs 30 can be individually changed by the respective coaxial screws 31. Pull cable 32
Are respectively connected to the coaxial screw 31 at one cable end thereof and are hooked at the respective deflection positions 33 provided on the front cuff 2. These deflection positions 33 also constitute the pivot position of the front cuff 2 on both sides of the longitudinal axis of the ski boot. The pull cable 32, only one of which can be seen in FIG. 5, further connects the rear spoiler 3 to the bottom shell, ie the lower shell 1, on each shaft side of a pivot shaft 34 located at the rear edge of the lower shell. Was guided to
Then, guided upwards, the other cable end is fixed to each side of a pulling lever 35 arranged at the rear of the unsplit rear spoiler 3. At the position of the pulling lever 35 shown in FIG. 5, the front cuff 2 and the rear spoiler 3 are in the boot closing position shown by the solid line. Preferably, when the pre-biased compression spring 30 is compressed by a sudden impact on the rear spoiler 3, the rear spoiler 3 assumes the position shown by the dashed line in FIG. According to the direction of force,
These compression springs 30 can be compressed in parallel or, alternatively, in an asymmetric manner. In this exemplary embodiment, the pivot shaft 34 of the posterior spoiler 3 is located at the posterior edge so that when posterior movement of the posterior spoiler 3 occurs, compression occurs in the area of the Achilles tendon and in the calf of the lower leg. Advantageously, it will be evenly distributed along. The pulling cable 32 is guided without changing the cable length or the circumferential pulling force depending on the back movement of the skier's leg.

Constructed in accordance with the present invention, FIGS.
In the fourth exemplary embodiment of the ski boot shown in FIG. 1, the pulling device 40 is arranged on the rear spoiler 3, ie in the middle of the back part of the rear spoiler 3. Pulling device,

Are arranged on one side of the front cuff 2, as can be seen in FIG. The longitudinal displacement of the tensioning device, i.e. the housing 41 of the tightening device 40, is effected by means of a Bowden control cable or wire 52, one end of which is fixed to the housing 41 and the other end of which is a self-actuating release mechanism, That is, it is fixed to the rocker lever 53 of the self-operation releasing mechanism 51. The function of this self-actuating release mechanism, that is, the self-actuating release mechanism 51 is apparent by referring to FIGS. 7 and 8. The rocker lever 53 can rotate about a shaft 54 supported by the housing portion 55. A torsion spring 56 supported on the housing part 55 pivots the rocker lever 53 away from the ski boots and is biased into the open position according to FIG. 8, which allows the Bowden control cable,
Alternatively, the wire 52 is actuated for the purpose of moving the pulling device, ie the housing 41 of the tightening device 40. However, this pivoting movement of the rocker lever 53 results in a holding bolt 57 guided in the housing part 55.
Blocked by. The retaining bolt 57 can be pushed out of the blocking position and pushed to the right against the action of the spring 58. This is a pin 59 guided in the housing part 55.
Achieved by this pin 59 is a rigid connecting element 60
Is connected to a rod or bar 61 extending substantially parallel to the pin 59. The other end of this rod or bar 61 is connected to a tension band, ie the releasable end 45 of the tension belt 44.
The rod or the flange 62 of the bar 61 supports one end of the compression coil spring 63 and the other end thereof by the housing portion 55. The compression coil spring 63 constitutes a damping element for the initial rearward movement of the rear spoiler 3 in the opening direction, eg a damping element when the skier falls backwards. As a result, the compression coil spring 63 is compressed to a certain range as shown in FIG.
The blocking retention bolt 57 releases the rocker lever 53 and the Bowden control cable or wire 52 is actuated, causing the rear spoiler 3 to pivot rearwardly, which allows the lower leg of the skier to move rearwardly. Like

Turning again to FIG. 6, this fourth exemplary embodiment of the ski boot of the present invention further includes a band fixed to the lower end of the rear spoiler 3 in a fixed position, ie the mounting position 65, or It has a belt 66, which is guided by a deflecting roll or a deflecting roller 67 arranged in the bottom shell 1, with the rear spoiler 3 in the position shown in broken lines, ie in dotted lines, rearward. The footbed 6 when pivoted, ie tilted
It turns out to be useful for lifting 8.

A fifth exemplary embodiment of a ski boot, constructed in accordance with the invention, shown in FIG. 9, has a pair of tension cables, one pair of which are fixed to the rear spoiler 3 at each end. With the closure means, the fixed positions are arranged in the longitudinal direction of the ski boot, i.e. on both sides of the longitudinal axis. These pulling cables 70 are guided on each side forward from a fixed position, downwardly in the front cuff 2 and hung on each deflection position 71, which deflection position 71 at the same time. Configure pivot position for cuff 2. The pull cable 70 is then passed over the front cuff 2, i.e. in the region of the instep, and pulled by a rotary pull closure 72 actuated by rotation. This tension closure 72 is held displaceably in the longitudinal direction of the ski boot, ie in the longitudinal axis, against the action of the spring element 73, ie the biasing force. This spring element 73 damply counteracts the impact forces exerted on the rear spoiler 3, for example when the skier falls backwards. After moving a predetermined amount of spring bias that allows the length of travel to be adjusted, the tension closure 72 completely releases the pair of tension cables 70 and stops tensioning, thereby pivoting in this embodiment. The rear spoiler 3, which is supported in the rearmost lateral region by means of a shaft or swivel shaft 74, can be pivoted rearward into the open position indicated by the phantom or dotted line.

The manner in which the exemplary embodiment of the ski boot shown in FIG. 9 can be realized and shaped in greater detail is shown schematically at an enlarged scale in the partially cutaway side view of FIG. The bottom or lower shell 1 of the ski boot has a chassis or trough 75 rigidly arranged in the region of the instep of the foot. A rotary drum housing 76 is provided on the chassis 75 so as to be movable in the longitudinal direction against the action of a compression spring 73 supported between the rotary drum housing 76 and the chassis 75. The rotary drum housing 76 accommodates a suitable rotary drum, which is not particularly shown and is rotatably mounted, and has a rotary knob connected to the rotary drum, that is, when the rotary head 77 is turned by hand. The front ends of the two pulling cables 70 are wound around this rotating drum. Only one of the front cable ends that has entered the drum housing 76 is visible in FIG. The rotary knob or rotary head 77 has on its lower circumferential edge a locking tooth 77a cooperating with a lever-type catch or detent 78, which detent 78 is rotatable on the rotary drum housing 76. When attached, tension cable 70 moves with rotating drum housing 76 when tension is applied in the direction to the right in FIG. In this way, the rotary drum housing 76 and thereby also the lever-type catch 78 are moved in the direction to the right in FIG. 10 against the action of the compression spring 73, ie the biasing force. The end portion of the right arm of the lever of the lever-type catch 78 then moves towards the cushion, i.e. the ramp stop surface of the ramp 79, which causes the rotary knob, i.e. the rotary head 7.
7 is unlocked and interrupted by the pivotal movement of the lever type catch or detent 78. Cable 7
During the zero pull, the rotary knob, ie the rotary head 77, which has been rotated counterclockwise for the purpose of winding the front end of the cable on the rotary drum, is no longer held and the pull cable 70 is now in the opposite direction. Released by possible rotation, the ski boot is released by tilting the rear spoiler 3 rearward. The buffer, that is, the lamp 79, is attached to the chassis 7 by the spindle 79a.
5, the position of the bumper or ramp 79 is changed by the knurling adjustment wheel 79b in the longitudinal or longitudinal axis of the boot to set the spring bias as required until disengaged. be able to.

11 and 1 formed in accordance with the present invention.
In the sixth exemplary embodiment of the ski boot shown in 2, the rear spoiler 3 likewise flexes rearward in an elastically damped manner, but the springs or spring elements are not involved in such actuation. Rather, this action is performed by the elastically bent or flexed portion of the rear spoiler 3. The rear spoiler 3 has a slot 81 in its lower region, i.e. below a pivot position 80 arranged on either side of the longitudinal axis of the ski boot, which slot 81 is designed to be fitted from one side of the boot to the boot. It is threaded on the opposite side and extends in a sloping manner to the back zone. Each slot end 82 on each side of the ski boot is located at a distance from the lower edge of the rear spoiler 3, and within the area of these slot ends 82, the rear spoiler 3 is releasable on each side of the shaft. It is held on the bottom shell, i.e. the lower shell 1, by means of a locking device, i.e. a releasable holding device 83. A rim region or boundary region 84 extending on either side between the pivot position 80 and the releasable locking device or releasable holding device 83 forms each bent web, ie each flexed web, and the web. Bends when the rear spoiler 3 is pushed backwards by the skier and assumes the position shown by the dashed or dotted line 85, which narrows the slot 81. The shrinkage, or narrowing, of the slots 81 on either side of the shaft can be more or less tightly limited by each slider 86 movable longitudinally within the lateral portion of the slot 81.
Thus, these sliders 86 serve to set the hardness of the backward tilt damping, which allows the sliders 86 to
Slot 81 as indicated by the dotted line in FIG. 11 of the drawings.
When positioned in the upper rear part of the lateral part of
Stronger hardness is achieved.

On the other hand, when a force is exerted in the direction of the forward inclination and acts, the rim area, that is, the boundary area 84.
Can flex downward, ie, bend, to the opposite side of the slot 81, and the hardness of the forward tilt damping force can also be set by the slider 86, thereby positioning the slider 86 in the lower front portion of the lateral portion of the slot 81. A stronger hardness is then achieved.

In order to pivot the rear spoiler 3 backwards and thereby allow the ski boot to be released, the releasable locking device, ie the releasable holding device 83, must be released. I have to. The locking device 83 is moved from each locking position by rotation. For this purpose, these locking devices 83 are connected to the eccentric detent pin 89 by a pulling means such as a cable 88, the pin 89 being rotatably mounted on the bottom of the rear part of the rear slider 3. .. This eccentric detent pin 89
Can be operated by hand with a ski pole,
Then, the rear spoiler 3 is rotated so that the lower rim of the rear spoiler 3 finally comes into contact with the edge 90 formed on the bottom shell, that is, the lower shell 1 (FIG. 12).
Also, this sixth of the ski boots shaped in accordance with the present invention.
In the exemplary embodiment, the closure means comprises a tension cable 91 fixed to the front cuff 2 on both sides thereof and a rear spoiler 3.
The pulling lever 92 is rotatably installed on the rear portion, that is, the back portion. By pivoting the pulling lever 92 to its open position and thereby releasing the pulling cable 91, this so-called mid-entry ski boot can be widely opened, since the front cuff 2 has a hinge 93. This is because it is attached to the bottom shell, that is, the lower shell 1.

The ski boot shown in FIG. 13 corresponds to the first exemplary embodiment shown in FIG. 1 with a rear spoiler 3 having a lower part 4 and an upper part 5. In addition, the ski boot has a saddle-like pressure plate or saddle-like pressure pad 100 therein, which is a means for being pressed against the instep of the skier. The saddle-shaped pressure plate 100 has a pulling mechanism 1 on each side thereof with a bowden control cable or wire 101.
02, the pulling mechanism 102 serves to pull each Bowden control cable or the wire 101, and is installed in the rear portion of the rear spoiler 3. The Bowden control cable, or the outer sheath end 103 of the wire 101, is rigidly mounted to the bottom or lower shell 1 of the ski boot. The function, or purpose, of this pressure plate 100 is to prevent the skier's foot from being unintentionally disengaged from the ski boots when the rear spoiler 3 is fully tilted to the open position during a backward fall of the skier. Is to The rearward inclination of the rear spoiler 3 is determined by the above-described pulling mechanism 10 installed in the rear zone of the rear spoiler 3 as described above.
With a backward tilt of 2. In this embodiment shown in FIG. 13, the Bowden control cable or wire 101 remains bowbow cable or wire length unchanged in the backward tilt path of the rear spoiler 3 as compared to conventional pull cables. And also when the rear spoiler 3 with the pulling mechanism 102 is tilted backwards to the open position, the pressure plate 100 is caused by the rigidly installed outer sheath end 103 of the Bowden control cable or wire 101: It excels in maintaining its holding position.

FIGS. 14 to 17 show a rear spoiler, for example, when the skier falls backwards, when the closing means is opened against the action of the spring force, ie the bias, according to the setting of the spring force. A seventh exemplary embodiment of a ski boot is shown in which 3 is adapted to pivot rearward and into the open position. The closing means shown in FIG. 14 has already been described in connection with the embodiment according to FIG. A tension cable, ie, a tension cable 70, is secured to each side of the rear spoiler 3 and guided downwardly in the front cuff, then upwards in the region of the instep and the rotary tension closure 72. The closure 72 is centrally attached to the front cuff 2 and is actuated by rotation. Apart from these closures shown in FIGS. 9 and 10, a closure means according to any of the other embodiments of the invention described above is shown in FIG.
Can be applied to ski boots. However, the ski boot further comprises a saddle-shaped pressure distributor 110 arranged in the region of the rear spoiler 3, ie between the rear spoiler 3 and the inner shoe, ie the inner shoe 111. , This pressure distributor 1
The 10 serves to be pressed into the area of the Achilles tendon of the ski boot wearer.

As can be seen especially from FIGS. 15 to 17, a pair of tension cables 112 guided in a cross shape abut on the outside of the pressure distributor 110 having a saddle shape. These pull cables 1
The upper ends of 12 are fixed to the adjusting devices 114 mounted on the upper left and upper right of the rear spoiler 3, respectively.
These adjusting devices 114 each have a spring element 113 and serve to adjust the length of the tension cable 112 guided in a cross shape. According to the illustration in FIG. 14, the lower ends of the pulling cables 112 are respectively connected to the rear spoiler 3
Is guided to a deflecting roll 115 located at the lower end of the shaft and then fixed to a pivot or swivel shaft 116. This shaft 116 of the rear spoiler 3 is arranged in this embodiment at the bottom end of the rear part of the rear spoiler 3. Obviously, these lower ends of the pull cable 112 can be arranged in various ways. For example, in the embodiment of FIG. 15, the lower end of the cross-guided pulling cable 112 is first properly hooked into each deflection guide 117 rigidly arranged in the bottom shell 1 and then the rear spoiler 3. Fixed to. Obviously, it is not necessary for the pull cables 112 to be arranged in a cross shape, but instead they can be arranged to run side by side. These pull cables 112
The arrangement and mode of operation of the rear spoiler 3 is such that when the rear spoiler 3 is tilted forward, the pressure exerted by the saddle-shaped pressure distributor 110 on the area of the Achilles tendon of the wearer of the ski boot increases and the rear spoiler 3 rotates backwards. It is supposed to decrease when moved. Thus, the skier's foot is optimally held in the normal ski position when the foot is tilted slightly forward. The ski boot of this embodiment is a so-called rear entry ski boot, and the rear spoiler 3 is rotated in the rearward direction about the horizontal lateral axis of the ski boot so that the skier leans on the rear spoiler 3 so that the ski can be mounted on the boot. It can be slid in. If such a rear-entry ski boot had to optimally hold the skier's foot in the normal ski position, then it would be necessary to provide a tightened or constricted rear spoiler 3. This means that the skier should have his foot on the rear spoiler 3
Again makes it difficult to slide over the narrowed area of. A solution to this problem is shown in the embodiment according to FIG. 16 in which the ski boot is shown in the ski position and in the rear open position, while the lower leg of the skier is shown in dotted position in both positions. From the drawing, the saddle pressure distributor 11
It can be seen that 0 is pressed in the area of the Achilles tendon in the ski position and in the open boot position it is arranged backwards so that the skier's foot can be moved in and out of the boot without obstruction. Let's see

Further, in FIG. 15, the rear spoiler 3 is shown.
As shown in FIG. 14, hinged to the rear end, or
It does not need to be supported, but can instead be pivotally attached to the bottom shell, ie the lower shell 1, by means of pivot pins 118, these pins 118 being arranged on either side of the longitudinal axis of the boot. It differs from the illustration in FIG.

While embodiments of the present invention have been shown and described, it should be understood that the present invention is not limited thereto but can be variously practiced within the scope of the claims. ..

The pressing force and foot holding action exerted by the pulling cable reach a maximum when the rear spoiler is pivoted forward in the closing direction to allow rear deflection of the rear spoiler. Ski boots. 16. The tension cables that impinge on the outer side of the pressure distribution means are arranged in a cross direction relative to each other, the tension cables from the spring elements each extending obliquely on the outer side and downward on separate sides. Proceed to
The ski boot according to claim 15. 17. The tension cable striking the outer side of the pressure distribution means extends side by side from the spring element on the outer side and travels downward on each side.
Ski boots as described in. 18. A ski boot having a bottom shell and a longitudinal axis, the ski boot having a front cuff, a rear spoiler rotatably supported by the bottom shell, and a closing means, the rear spoiler closing the closure. Connected to said front cuff by means, said rear spoiler having a lower region, a rear spoiler lower edge, a back zone and a side constituted by respective sides of a longitudinal axis, said rear spoiler Is in the lower region from one side of the rear spoiler to the other side of the rear spoiler,
A slot extending obliquely up to the back zone, said slot terminating at a predetermined distance from the lower edge of the rear spoiler on both sides, the bottom shell being provided with pivot means, the pivot means being longitudinal Positioned above the slot on either side of the axis, the pivot means defining a pivot axis extending transversely to the longitudinal axis, and the rear spoiler between the open and closed positions. Pivotally engaging the pivot means for pivotal movement about an axis and having releasable locking means on each side positioned below and in front of the ends of the slots, the rear portion The spoiler is retained on the bottom shell by the releasable locking means and the rear spoiler is releasable with the pivot means on both sides. A rim zone extending substantially parallel to the slot and forming respective flexure webs, the flexure webs being acted upon by the impact force acting rearward on the rear spoiler. Ski boot that bends in one direction and damps the rotational movement of the rear spoiler in the opening direction as an elastic member. 19. The slot of the rear spoiler comprises longitudinally moveable sliders on each side of the rear spoiler that rigidly limit somewhat the contraction of the slot according to the position within the slot, respectively. The contraction causes the flexible webs of the rim zone to flex on both sides, and the setting of the slider in the slot, the resulting restriction of the contraction of the slot, adjusts the hardness of the rear slope damping. 19. or optionally, the upper portion slopes forward to help adjust the hardness of the forward slope damping when the flexible web bends in the opening direction. Ski boots as described in. 20. The releasable locking means useful for retaining the rear spoiler in the closed ski position,
An eccentric detent pin is provided at a lower end of the back zone, one end of each friction member is fixed to the eccentric detent pin, and each friction member is attached to each side of the rear spoiler. The front end is fixed to each releasable locking means, and the locking means on both sides of the rear spoiler further rotate the rear spoiler in the opening direction to cause the eccentric detent pin. 19. The ski boot of claim 18, wherein the ski boot is removed by activating.
