Abstract

In the heel area of a ski boot a rubber torsion spring element is arranged, the core piece of which is anchored in a rotationally fixed manner on the lower shell of the ski boot by means of a bracket. An outer tubular piece, which surrounds the core piece coaxially, is connected to a tension member which engages with its end at the rear on a rear shaft part of the boot shell. The rear shaft part and a front shaft part are pivotable relative to the lower shell about an articulation axis into a forward lean position. The spring element damps the forward lean movement and, by means of the use of snappy rubber compounds, is extensively independent of the ambient temperature. Additionally, it allows the adjustment at least of the starting point of the spring or damping effect by means of a knurled nut.

Description

The invention relates to a ski boot mentioned in the preamble of claim 1.

From CH-PS 529 524 a ski boot is known which has a lower shell and a shaft part which is movable with respect to the lower shell in the direction of advance. The shaft part is connected to the lower shell by means of rubber-elastic disks at two points opposite one another with respect to the center plane of the shoe and defining a joint axis. These discs form the only connection between the lower shell and the shaft part. Different damping effects can be achieved by selecting discs with different properties. After assembling the lower shell and the shaft part, however, it is no longer possible to change the damping properties easily. The fact that the discs are arranged at the articulation points of the shaft part on the lower shell means that the freedom for the structural design of the ski boot is restricted. In addition, the panes are accessible from the outside and are therefore exposed to environmental influences.

The present invention has for its object to provide a ski boot of the type mentioned, the design options are limited as little as possible by the damping arrangement and the damping arrangement of simple structure and largely independent of temperature influences and a damping effect corresponding to the respective requirements even over a long period can unfold.

According to the invention, this object is achieved by the features of the characterizing part of claim 1.

The special design of the rubber spring element results not only in a progressive spring characteristic, but also in a limitation of the spring travel by the spring element itself. This has the particular advantage that no hard and uncomfortable stop is required to limit the spring travel. The damping effect arises from a rotating and flexing movement of the rubber-elastic body with a relative twisting between the core piece and the pipe piece. For the rubber body, materials can be used that have already proven themselves for similar uses, preferably materials based on natural rubber or synthetic elastomers. In particular through the use of highly elastic rubber compounds, such a spring element is not subject to any significant temperature influences within the area of application, so that a constant spring effect can be expected.

Because the rubber spring element of the damping arrangement is arranged outside the hinge axis and is preferably accommodated in the lower shell, there is a great deal of freedom in the configuration of the ski boot.

Rubber spring elements of the type used in the ski boot according to the invention have long been known per se, but have hitherto been used for other purposes (see, for example, FR-A-957 495 and CH-A-423 357).

In one embodiment according to claim 2, the rubber spring element provides an elastic connection between the shoe sole or the lower shell and the force transmission element forth, which in turn attacks the shaft. A non-rotatable connection to the shoe sole or lower shell relates only to the spring action of the spring element, but not to its adjustment option in order to achieve a basic setting.

In a preferred embodiment according to claim 3, the rubber spring element is housed in a particularly protected location, so that a risk of accident or damage is completely excluded, especially if the spring element is completely housed within the shoulder. In addition, the risk of pollution is relatively low with such accommodation. In the embodiment according to claim 5, the spring characteristic can be adjusted so that a ski boot equipped with such an element can be adapted to the skills of the skier.

A particularly preferred embodiment results according to claim 6, by means of which the spring characteristic can be adjusted by the skier himself with simple and easily accessible means. Despite this individual possibility of adjusting the flex effect by changing the preload, there is no restriction on the angle of rotation and thus the spring travel.

By a preferred embodiment according to claim 7, the position of the upper relative to the shoe sole or to the lower shell can be selected in which the spring action is zero. Starting from this "zero position", a spring action is possible both in the forward and backward directions and depends on the arrangement of the force transmission element.

In one embodiment according to claim 8, the spring action is limited to a movement in the direction of advance.

Claim 9 describes a preferred embodiment for adjusting the rest position or the point of application of the spring action in connection with claim 8. The nut used for adjustment can be, for example, a knurled nut, so that the adjustment at the rear of the shaft can be carried out by the skier himself at any time and without tools .

Claim 10 describes a possibility for setting the rest position or the point of use of the spring action when the force transmission element acts on the shaft without the possibility of adjustment. In the embodiment according to claim 10, the setting is generally carried out by means of a tool, so that such an embodiment is advantageous if an inadvertent adjustment is to be avoided.

In an embodiment according to claim 11, the spring action is limited to a movement in the direction of advance, but the rear shaft part can be opened for loading without stressing the spring element.

In one embodiment according to claim 14, a connection which is rigid in both directions is present between the spring element and the shaft, so that the spring action of the spring element is stressed both in the direction in which it is presented and in the return direction.

In one embodiment according to claim 13, just as in that according to claim 12, there is a spring effect on the shaft in both directions, but the different geometry of the force transmission elements results in a different distribution of the spring characteristic on the swivel angle of the shaft.

Claim 14 describes an embodiment in which a double-sided effect of the spring element is also transmitted to the shaft by means of ropes or chains.

In an embodiment according to claim 15, the spring action is transmitted only in the forward direction, while in an embodiment according to claim 16, the spring action is transmitted both in the original and in the return direction. It is clear to the person skilled in the art that, starting from the spring element, the ropes must first run parallel to the sole surface in order to then lead them via deflection elements along the inner wall to the points of attack on the shaft.

In one embodiment according to claim 17, two spring elements are nested one inside the other. The effect of these can be arranged either in parallel according to claim 18 or in series according to claim 19. These possibilities give the person skilled in the art the opportunity to select the arrangement depending on the desired spring action.

An arrangement according to claim 20 is particularly advantageous if a low overall height is to be achieved.

Claim 21 shows a possibility to supplement the characteristic of a spring element.

The ski boot shown in FIG. 1 has a shoe sole 10 with a shoe shell 12 arranged thereon, which consists of a lower shell 14 firmly connected to the shoe sole 10 and a shaft consisting of a front shaft part 16 and a rear shaft part 18. The two shaft parts 16 and 18 are articulated on the joint axis 20 lying horizontally and transversely to the longitudinal axis of the shoe on the lower shell 14 and are held together by a buckle 22 in the upper region. Compressible ribs 24 are arranged between the lower shell 14 and the front shaft part 16. A double arrow 26 designates the mobility of the two shaft parts 16 and 18 relative to the shoe sole 10. The lower shell 14 and the shaft parts 16 and 18 are shown broken away in the heel area in order to make a damping arrangement 28 in this area visible. The damping arrangement 28 has a torsion rubber spring element 30 on the core piece 32 of which is rigidly connected to the lower shell 14 by means of an anti-rotation tab 34. The spring element 30 also has a tube piece 36 which is rotatable relative to the core piece and to which a tension band 40 is fastened on the circumferential side by means of a screw 38. At its other end the drawstring 40 is connected to a threaded bolt 42 which engages on the rear shaft part 18 by means of a knurled nut 44. The knurled nut 44 is held in the rear shaft part 18 by means not shown and is accessible from the outside through a window 46.

The shaft 16, which consists of the parts 16 and 18 and can be swiveled with respect to the sole of the shoe 10 by the articulation axis 20 and the transverse ribs 24, enables the skier wearing the shoe to assume a position in which the leg is in a forward inclined position relative to the foot. The damping arrangement 28 serves on the one hand to dampen the original movement and on the other hand to resiliently return the shaft to a rest or starting position. With a movement of the original, the tension band 40 is tightened in order to partially unwind from the tube piece 36. Since spring elements (not shown in FIG. 1) are arranged between the core piece 32, which is anchored in a rotationally fixed manner on the lower shell 14, and the tube piece 36 coaxially surrounding the core piece 32, a spring force is exerted on the tension band 40 and thus on the rear shaft part 18.

Figure 2 shows on a larger scale in principle the same damping arrangement as Figure 1, but with the configuration that the spring action of the torsion rubber spring element 30 'is adjustable. For this purpose, the core piece 32 'is designed as a slotted expansion body which is spread when an Allen screw 48 is screwed in, in order to increase the pretension on the body 50, which is arranged between the core piece 32' and the tube piece 36, and consists of a rubber-elastic material.

FIG. 2 also shows that the core piece 32 'has a square shape on its outside and the tube piece 36 on its inside. The embedded between these two parts, consisting of a rubber-elastic material body 50 give the rubber spring element 30 or 30 'the effect of a torsion spring, since they limited rotation of the two parts having a square shape 32 or 32' and 36 relative enable each other. Usually are the body 50 made as a rubber body based on natural rubber. Since such a rubber is not compressible, the angle of rotation of such a spring element is generally limited to approximately ± 30 °. When used as a torsion spring, the rubber bodies are subject to a twisting and flexing movement. For use in ski boots, rubber bodies have the particular advantage that their spring characteristics are hardly influenced by the ambient temperature within wide limits. Of course, instead of rubber, the use of rubber-like plastic is also possible, provided that this is also not temperature-dependent in the area of application.

It can be seen from FIG. 3 that the Allen screw 48 has a conical projection 52 in order to spread the core piece 32 ', which is designed as a slotted expansion body, in a wedge shape.

It can also be seen from FIG. 3 that the tension band 40 has an elongated hole 54 which extends in the longitudinal direction and is fastened by means of the screw 38 to the pipe section 36 (FIG. 2). The screw 38 then has a thread-free shoulder on its head in order to allow the tensioning strap 40 to be displaced in the longitudinal direction when tightened. This displacement is necessary in order to be able to pivot the rear shaft part 18 to the rear for opening and getting in. When the shaft part 18 is closed, the slot 54 rests with its end 54 'on the shaft of the screw 38. The screw 38 therefore does not serve to fix the tension band 40 directly, but rather as a stop screw.

FIG. 4 shows an embodiment in which a lever 56 is arranged on the spring element 30 instead of a tension band as a force transmission element, said lever 56 articulated via a pull rod 58 either on the front shaft part 16 or on the rear shaft part 18. It is also possible for the pull rod 58 to be connected to both shaft parts 16 and 18. The pull rod 58 can be arranged on the inside or outside of the shoe. It can also be seen from FIG. 4 that the spring element 30 is installed in the heel area below the insole 60.

In the case of an embodiment according to FIG. 4, it is possible to arrange the lever 56 either on the core piece 32 or on the tube piece 36 and to anchor the other end of the spring element 30 in a rotationally fixed manner either on the lower shell or on the shoe sole 10.

Figure 5 shows an embodiment in which the force transmission member is formed by the spring element 30 looping ropes or chains 62 which engage with their two ends 62 'and 62˝ on the front shaft part 16. One point of attack 62 'is behind and the other 62˝ is in front of the hinge axis 20th

In an embodiment according to FIG. 6, a lever 64 is arranged as a force transmission member on the spring element 30, which lever is connected to an extension 68 of the front shaft part 16 by means of an elongated hole 66 extending in the longitudinal direction in the lever 64 Driver pin 70 attacks. In this embodiment, the lever 64 is connected to the core piece 32, while the tube piece 36 of the spring element 30 is anchored in a rotationally fixed manner to the lower shell 14 or the shoe sole 10.

FIG. 7 shows an embodiment which essentially corresponds to that according to FIG. 1, but in which the spring element 30 on its anti-rotation bracket 34 is adjustable within a limited angle. The adjustment option is indicated by 34 '. Due to the adjustment option, the rest position or the point of application of the spring action can be adjusted in order to be able to adapt the ski boot to the needs of the skier.

In an embodiment according to FIGS. 8 and 9, of which FIG. 9 only shows the spring element 30 and the force transmission members, the spring element 30 is mounted so as to be overhung in the longitudinal direction of the shoe. Four cables 72, 74, 76 and 78 serve as power transmission members, each of which is anchored at one end to the spring element 30 and with its other end to the front shaft part 16 at points of attack 72 ', 74', 76 ', 78'. In principle, it is also possible to arrange only the two ropes 72 and 74, which, viewed in the longitudinal direction of the ski boot, engage behind the hinge axis 20 on the front shaft part 16. On the spring element 30, the one rope 72 is connected to the core piece 32 of the spring element 30 via a lever 80, while the other rope 74 is fastened to the jacket of the tube piece 36 of the spring element 30 and partially wraps around the spring element. If the shaft of the ski boot is covered by the Skiers are now loaded in the direction 82, then the ropes 72 and 74 are tensioned so that the core piece 32 rotates in one direction and the tube piece 36 in the opposite direction.

If the ropes 76 and 78 are now also arranged between the spring element 30 and the front shaft part 16, then they perform an opposite movement to the ropes 72 and 74, since they are attached to the spring element 30 crosswise to the ropes 72 and 74 mentioned first and also engage the front shaft part 16 in front of the joint axis 20. The crosswise arrangement between the rear ropes 72 and 74 and the front ropes 76 and 78 is achieved by connecting the right rope 72 from the rear ropes to the core piece 32 via the lever 80, while the left rope 78 is connected from the front ropes is connected to the same core piece 32 via a further lever 84. The arrows 86 shown in broken lines denote the deflection direction in the case of an original movement.

The difference between an arrangement with two ropes and an arrangement with four ropes is that the spring action with two ropes is only present in the forward direction, while with an arrangement with four ropes the same spring element 30 also develops its spring force in the return direction. The flying bearing of the spring element 30 is to be understood to mean that both the outer tube piece 36 and the inner core piece 32 can be moved relative to one another without anchoring to a stationary part of the ski boot.

In one embodiment of a spring element 88 according to FIGS. 10 and 11, two spring elements are coaxially nested in one another according to the principle explained for FIG. The outer tube 90 of the inner spring element 92 also forms the core of the outer spring element 94. The outer cage 96 of the outer spring element 94 is fixed in a holder 98 and the core 100 of the inner spring element 92. The outer tube 90 serves as a movable part inner spring element 92 which is rotatably connected to a lever 102. The outer spring element 94, like the inner spring element 92, has bodies 95 made of a rubber-elastic material.

In the arrangement shown in FIGS. 10 and 11 and described above, the inner spring element 92 and the outer spring element 94 are operatively connected in parallel. However, it is also possible to connect the spring elements 92 and 94 arranged coaxially to one another in series. For this purpose, contrary to the embodiment shown, the lever 102 would not have to act on the outer tube piece 90 of the inner spring element 92, but rather on the core piece 100 thereof. Of course, the core piece 100 should then not be held stationary. The outer pipe section 90 of the inner spring element 92 would then be free. The advantages of a series connection are firstly the double angular path of two coaxially arranged spring elements and the very soft progression of the flexibility curve. Here, too, it is possible to achieve the flexibility curve by changing the volume of the core 100 by screwing conical screws 104, 104 'at both ends more or less into conical bores 106, 106' will. The prerequisite is, of course, that the core pieces 100 are designed as expansion bodies in the same sense as in an embodiment according to FIGS. 2 and 3.

As FIG. 11 shows, the entire spring element 88 is arranged symmetrically on both sides of the lever 102.

FIG. 12 shows an arrangement with two spring elements 108 and 110 arranged in parallel next to one another, which are also connected in parallel in terms of their effectiveness. These two spring elements are provided with a toothing 112 over at least part of their circumference or they have attached gearwheels. The toothings 112 of both spring elements 108 and 110 intermesh, so that they must inevitably perform an opposite movement. The core piece 114 of the spring element 108 is anchored in place by means of a holder 116. A tension band or tension cable 120 is fastened to the outer tube piece 118 of the second spring element 110 by means of a screw 122. Forces acting in the direction of arrow 124 on the drawstring or pull cable 120 act uniformly on both elements, irrespective of which of the two elements is actuated. This arrangement is advantageous in order to double the forces with a flat overall height. The arrangement can be expanded by adding two plus one etc. elements.

In an embodiment according to FIG. 13, a further body 132 made of a rubber-elastic material is arranged between the outer tube piece 126 of a spring element 128 and a fixed anchor 130. The centerpiece is also firmly anchored 134. A drawstring or pulling rope 136 engages on the outer pipe section 126. In the embodiment according to FIG. 13, the rubber-elastic body 132 is connected in parallel with the spring element. Such an embodiment can also help to use a spring element with a relatively small diameter in order to achieve a low overall height.
