EP0595176B1 - Sole support plate - Google Patents

Description

The invention relates to a sole support plate for ski boots in ski bindings according to the first part of claim 1, 8 or 10.

Such a sole support plate is known from document EP-B1-0 345 371.

In this known solution, the sole support plate essentially consists of a base plate resting on the top of the ski and a step plate arranged above it, which cooperates with the base plate via inclined surfaces that decrease or increase in the longitudinal direction of the ski such that a relative displacement of the step plate and the base plate in the longitudinal direction of the ski increases a height adjustment of the tread plate relatively leads to the ski or the base plate. The design is such that between the base plate and the tread plate, in addition to the above-mentioned inclined surfaces, which are of stepless design and in particular are flat, there are cooperating control surfaces which run obliquely to the ski direction, one of which is adjustable relative to the other in the ski direction, such that the adjoining control surfaces determine the relative position of the base plate and the tread plate in the longitudinal direction of the ski and when the control surfaces are adjusted in the transverse direction of the ski, the base plate and the tread plate change their relative position in the longitudinal direction of the ski, thereby changing the height of the tread plate relative to the base plate or the ski. This results in the mandatory use of a control slide, which is to be actuated by means of a threaded rod mounted in the tread plate. Thus, the entire structure of this known sole platen is expensive to manufacture and cumbersome to operate. There is also a risk of icing.

From document FR-A-2 431 306 (Figures 6 to 9) a sole support plate for ski boots in ski bindings is known, which can be releasably attached to a ski-fixed base plate and, in its assembled state, lies at least partially on the upper side of the base plate, and with two mutually opposite and perpendicular side surfaces is supported on corresponding guides of the base plate, which sole support plate has a supporting body and one on this relative to one Sole hold-down device for the ski shoe sole has a holding plate which can be brought to different heights. Viewed in the longitudinal direction of the ski, receiving parts are formed on the support body at a distance from one another and counterparts corresponding to the receiving parts on the holding plate. Even if the receiving parts and the counterparts, viewed in the vertical direction, have different distances in pairs and can thus determine the support for the ski shoes running at different heights by displacing the holding plate relative to the support body, this sole support plate has some disadvantages. To secure the holding plate on the support body against unintentional lifting, a locking device formed from a screw and a screw thread is required, which must be released with each adjustment of the holding plate relative to the support body and tightened again after moving the holding plate into the desired other position. Thus, in this known sole support plate, a total of four components are required to secure the holding plate relative to the supporting body against displacement in the horizontal or lifting off in the vertical. Furthermore, it is also disadvantageous in this known solution that the relatively long structure of the support body by stiffening the skis can have an undesirable influence on it. Furthermore, the space requirement and the weight of the sole support plate are undesirably increased in this embodiment.

Another sole pad is disclosed in document AT-B-368 900.

In this embodiment, the sole support plate consists of two parts which can be displaced relative to one another, the lower part and the upper part being wedge-shaped, viewed in the direction of the ski axis. The lower part carries a toothed rack, which is intended to snap in a spring tooth that is attached to the upper part. Thus, two components, namely the two side surfaces with the corresponding guides and the toothed rack with the locking tooth, are required to secure the holding plate relative to the support body against displacement in the, albeit oblique, horizontal and against lifting off in the vertical. This means that a total of four components are required. Even if this embodiment allows a batchwise higher or lower setting of the entire sole support plate, however, it has the disadvantage that the rack has relatively steep teeth in order to exclude with certainty an undesired displacement of the upper part relative to the lower part. Another disadvantage is that relatively long components are required to adjust the upper part, which unnecessarily increases the space requirement and the weight of the sole support plate.

A similar sole support plate as in EP-B1-0 345 371 is disclosed in AT-PS 356.561. However, this known device only allows a ski shoe to be put on at a predetermined altitude.

There are already known in various versions sole support plates for ski boots in ski bindings, which allow adaptation to different shoe sole thicknesses. For example, reference is made to documents CH-A-212.583, US-A-4,135,736 and US-A-4,586,727. The CH document discloses a wedge-shaped underlay under the heel of the ski boot, which underlay can be displaced in the longitudinal direction of the ski and can optionally be locked by means of a locking device at counter-detents which are spaced apart from one another. However, this known sole support plate can only be moved under the heel of a ski boot and there only to a limited extent, because otherwise it is not a secure support is guaranteed for the ski boot. For this reason, the angle of inclination of the wedge is relatively narrow.

In the various embodiments known from document US-A-4,135,736, either displaceable wedge elements are displaced in the region of the sole support plate in the longitudinal direction of the ski, or the holding plate is raised or lowered by a displaceable support. However, the fastening screws must be loosened and tightened again after the adjustment, which can result in repeated manipulations. In addition, in this known solution, in some embodiments, increased friction can arise between the sole support plate and the ski boot sole if the support is placed at an acute angle between these parts.

In the case of a further height-adjustable sole support plate according to the document US-A-4,586,727, a holding plate with the sliding plate is height-adjustable in the holding body by means of a wedge piece which can be displaced in the longitudinal direction of the ski . The length of the entire sole support plate is defined by the fact that the supporting body has deformable supports, preferably made of a plastic material of the nylon type, on both its front and rear end regions, so that when the wedge is adjusted to increase the position of the holding plate, the latter occupies the desired elevated position without changing the length of the sole support plate. However, it is disadvantageous that the two end sections of the support body consist of a deformable plastic material, which means that repeated repetitions, in particular also in the event of changing weather conditions (cold due to the outside temperature, heat due to solar radiation), result in material fatigue and therefore fractures can arise. With considerable differences in height, the stress on the two end sections of the support body is particularly high.

Due to the advancement of the standard provisions also for ski boots, the variation of the ski boot thickness has decreased significantly in the past few years, whereby two shoe sole thicknesses are common - namely those for adults and those for children - while adhering to permitted tolerances.

The invention has set itself the goal of proposing a sole support plate for these two types of ski shoe soles, which ensures a safe and predetermined support for both types of ski shoes without the sole support plate itself being overstressed. In addition, it should be possible to combine the components required for securing the holding plate to the supporting body against displacement in the horizontal and against lifting off in the vertical.

According to the invention, the object is optionally achieved by the characterizing features stated in claims 1, 8 or 10. Characterized in that according to the first characteristic group of features of claim 1 on the support body in two vertically spaced sections one above the other receiving parts and on the holding plate also in two vertically spaced sections with the receiving parts corresponding counterparts, the possibility is created according to second characteristic group of features of claim 1 to bring the holding plate into engagement with all of its counterparts with the receiving parts of the supporting body or only the counterparts provided in the lower section of the holding plate with the receiving parts provided in the upper section of the supporting body and thus optionally a lower and an upper height position to determine the sliding plate.

Due to the characterizing features of claim 8, a lower and an upper height position of the sliding plate are determined by the fact that two higher and two lower, respectively cranked receiving parts are provided on the supporting body, with which two counterparts formed as inserts, each having a recess, are optionally available can be fixed on the bends of the two higher or lower receiving parts of the support body.

Characterized in that two pairs of receiving parts of different depth are provided in the support body according to claim 10, and a recess with a smaller depth is formed following a recess with greater depth, the holding plate, viewed in the vertical direction, has shorter and longer inserts, optionally in the receiving parts of different depth can be used and the shorter use determines a horizontal course of the top of the holding plate with the sliding plate, the goal set is achieved in this embodiment.

All embodiments according to claims 1, 8 and 10 are further common that the holding plate is supported relative to the support body against displacement in the horizontal and is held against lifting in the vertical of the mutually engaged counterparts and receiving parts by positive locking. In this way it is ensured that only two types of mutually engaging components are required for all embodiments, which are effective both horizontally and vertically. It is therefore neither necessary to unlock a resilient tongue as in the prior art, nor to loosen and tighten a screw as in document FR-A-2 431 306.

The overall length of the sole support plate does not exceed the overall length of a conventional sole support plate with a single height. Furthermore, the holding plate is moved to different heights, each in parallel planes to each other so that the friction between the sliding plate arranged on the upper side of the holding plate and the ski boot sole is kept constant.

The configuration and arrangement of the receiving parts on the support body and the counterparts on the holding plate enable various advantageous configurations of the invention, which are characterized in the dependent claims 2 to 7, 9 and 11 to 14. These advantages and further details of the invention will now be described with reference to the drawing, which shows several embodiments. 1 to 5 and 5a show a first embodiment of the invention, FIGS. 1 and 3 each showing a longitudinal section of the sole support plate in the low and in the higher elevation, respectively. FIG. 2 is a plan view of FIG Figures 4 and 5 are sections along the lines IV-IV of Figure 1 and VV of Figure 3, and Figure 5a is an exploded view of Figures 4 and 5 on a larger scale, Figures 6 and 7 a second and FIGS. 8 and 9 each show a third embodiment of the invention in cross section, similar to FIGS. 4 and 5, FIGS. 10 to 13 show a fourth embodiment of the invention, FIGS. 10, 11 and 11a being longitudinal sections and FIGS. 12 and 13 each being a cross section along the line XII-XII of FIG. 10 or along the line XIII-XIII of FIG. 11, FIGS. 14 and 15 are a fifth embodiment similar to FIGS. 4 and 5 and 15a, a detail of this.

In the following description, the same components have been identified with identical reference numerals, but to distinguish them in the second to fifth exemplary embodiments with increasing numerals 100 to 400. It should be noted that the component sometimes referred to as a holding body in the introduction to the description is subsequently referred to as a supporting body and the component resting thereon as a holding plate.

In the first exemplary embodiment according to FIGS. 1 to 5 and 5a, on the top 10a there is a ski which is only indicated 10 a sole support plate 1 according to the invention with an only indicated ski binding, which is designed as a toe 11, is arranged. A base plate 11a can be seen, by means of which the front jaw 11 can be fixed on the ski 10 by means of only indicated fastening screws 12. 1 and 3 each show a ski shoe 13 with its outlines, the thickness of these ski shoe soles 13a1 and 13a2 being different.

The sole support plate 1 has a supporting body 2, a holding plate 3 with a sliding plate 4, wherein the holding plate 3 with the sliding plate 4 can be arranged on the supporting body 2 at different heights. The structure of the base plate 11a is also known, as is the fastening of the slide plate 4 on the upper side of the holding plate 3, so that these details will not be discussed further.

ist, so daß die gesondert nicht bezeichnete Oberseite jeder Skischuhsohle 13a1 bzw.13a2 immer in der gewünschten Lage unterhalb eines Sohlenniederhalters 11b des Vorderbackens 11 liegt.In contrast, the arrangement of the holding plate 3 on the support body 2 at two different heights, which have been designated h1 and h2 in FIGS. 4 and 5, is new and inventive. In Figures 1 and 3, the associated ski shoe soles 13a1, 13a2 are designated with a height H1 and H2, respectively, from which it can be seen that $\text{h1 + H1 = h2 + H2}$

is, so that the separately not designated top of each ski boot sole 13a1 or 13a2 is always in the desired position below a sole retainer 11b of the toe 11.

In order to be able to show the structure of the support body 2 and the holding plate 3 with the many individual elements more clearly and to better describe them, these were illustrated in FIG. 5a in an exploded view and on a larger scale. In this way, details of the receiving parts of the support body 2 and the inserts of the holding plate 3 in FIGS. 4 and 5 are unnecessary to be provided with reference numbers.

In order to achieve the above-mentioned adjustment of the holding plate 3 to the different height positions h1 and h2, the inner structure of the sole support plate 1 in this exemplary embodiment is as follows. The base 2k of the support body 2 rests on the top 10a of the ski 10. The support body 2 has four receiving parts 2a to 2h in two sections 2i, 2j, one above the other, these receiving parts being formed by groove-like guides. In the lower section 2i of the support body 2, both the outer receiving part, which consists of two separate sections, and the central receiving part are each designed as a dovetail guide 2a, 2c, whereas the other two, between the aforementioned dovetail guides 2a, 2c lying receiving parts are designed as flat guides 2e, 2g. Both the outer and the middle dovetail guide 2a, 2c extend to the base 2k of the support body, whereas the flat guides 2e, 2g end at a distance from the base 2k and thus each form a web 2m, 2n in the lower section 2i of the support body 2. As a result, the strength of the support body 2 is practically unchanged even when the holding plate 3 is brought into the upper height position h2, as is illustrated in FIG. In the upper section 2j of the support body 2, all the receiving parts are each in the form of a dovetail guide 2b, 2d, 2f, 2h. Furthermore, it is only understandable that both the dovetail guides and the flat guides are dimensioned such that the holding plate 3 can be moved from one height position to the other with certainty. By selecting an appropriate design between the receiving parts of the support body 2 and the counterparts of the holding plate 3 to be described, a secure and shift-resistant hold between these two components of the sole plate 1 can be achieved even without a separate measure.

The holding plate 3 has the receiving parts 2a - 2h associated counterparts 3a - 3h, which are designed as inserts 3a - 3h which can be inserted into the guides 2a - 2h of the support body 2, and with the guides 2a - 2h of the support body 2, each of which they are assigned, are congruent. Thus, a lower section 3i and an upper section 3j can also be seen on the holding plate 3, each insert also having a lower section and an upper section. In the lower section 3i of the holding plate 3, the inserts 3e, 3g are each designed as a flat piece in accordance with the smaller depth of the guides 2e, 2g, otherwise all the other inserts 3a, b, c, d, f, h are each dovetail-shaped. In the lower height position h1 of the holding plate 3, the individual sections 3i, 3j of the holding plate 3 are in engagement with the sections 2i, 2j of the supporting body 2 which are associated with them and all the inserts 3a - 3h are in engagement with the guides 2a - 2h which are associated with them. In the upper height position h2 of the holding plate 3, the inserts 3a, c, e, g located in the lower section 3i of the holding plate 3 engage with the guides 2b, d, f, h located in the upper section 2j of the supporting body 2.

As can best be seen in FIG. 2, the holding plate 3 has two tongue-like locking arms 3p, 3q at its end region remote from the ski boot 13, at least on one of these locking arms, in the present exemplary embodiment on the latch arm 3q, a latch 3r is provided which engages in a latching recess 11c of the base plate 11a in the assembled state of the sole support plate 1. In this way, the holding plate 3 on the support body 2 is secured against unwanted and undesired shifting in the longitudinal direction of the ski in a simple manner, wherein the release for an adjustment of the holding plate 3 can be easily done.

To move the holding plate 3 from one height position to the other, a tool, e.g. a screwdriver, inserted between the vertical side surfaces of the base plate 11a and the holding plate 3, then the screwdriver is rotated or pivoted until the catch 3r is removed from the catch recess 11c. In this position, the holding plate 3 can be pushed down from the support body 2 in the longitudinal direction of the ski, moved to the other height position and pushed on again. It is only understandable that the locking recess 11c of the base plate 11a has a height which ensures engagement of the detent 3r at any height h1 or h2 of the holding plate 3.

The second exemplary embodiment of the sole support plate 101 shows a modification of the first embodiment according to FIGS. 1 to 5 in FIGS. 6 and 7. In this case, the two outer receiving parts of the supporting body 102 are designed as flat guides 102a, 102b which are elongated outwards in the lateral direction. The remaining receiving parts are designed unchanged as dovetail guides 102c-102h. In its lower section 103i, the holding plate 103 has an insert formed as a flat piece 103a on the sides, whereas the remaining inserts 103c, 103e, 103g, in accordance with the first exemplary embodiment, have a dovetail shape. The same applies to the inserts 103b, 103d, 103f and 103h present in the upper section 103j. This measure has the advantage that the holding plate 103 is held more securely against lateral impacts on the support body 102, and that the stability of the sole support plate 101 in the upper height h2 of the holding plate 103 compared to the first embodiment is improved.

In the third exemplary embodiment according to FIGS. 8 and 9, the connection between the support body 202 and the holding plate 203 of the sole support plate 201 is formed, similarly to the two previously described exemplary embodiments, by receiving parts and counterparts which are designed as guides or inserts. However, in this exemplary embodiment a total of six receiving parts are provided, all of which are designed as flat guides 202a-202h, the two outer guides 202a, 202b being larger than the remaining guides 202e-202h. Furthermore, the two lower inserts 203a of the holding plate 203 are longer than their other inserts 203b, 203e, 203f or 203g, 203h. In this way, the holding plate 203 is held against lateral impacts even more securely than in the embodiment according to FIGS. 6 and 7 on the supporting body 202 and the stability of the sole support plate 201 is maintained virtually unchanged even in the upper height h2 of the holding plate 203 with the sliding plate 204 lying thereon . It is only understandable that the two upper outer guides 202b are formed for this purpose as deep as the two lower outer guides 202a.

In the fourth embodiment according to FIGS. 10 to 13, two higher and two lower, respectively cranked receiving parts 302a, 302c and 302b, 302d are arranged on the support body 302 of the sole support plate 301, as can be seen in particular from FIG. 11a. As further illustrated in FIGS. 12 and 13, the receiving parts 302a and 302b are provided in pairs symmetrically to the longitudinal axis of the sole support plate 301. For the sake of symmetry, only the half-cuts were shown in each of these figures. In the assembled state of the sole support plate 301 and viewed in the longitudinal direction of the ski, the lower receiving parts 302b, 302d with their offsets 302b1, 302d1 toward the base plate 311a and the higher receiving parts are on the base 302k of the supporting body 302 302a, 302c with their offsets 302a1, 302c1 attached away from the base plate 311a (see FIGS. 10, 11 and 11a).

As counterparts, the holding plate 303 has only two inserts 303b, 303d, each with a pair of recesses 303b1,303d1, with which recesses the holding plate 303, in its lower height position h1, on the offsets 302b1,302d1 of the two lower receiving parts 302b, 302d of the support body 302 is definable. The inserts 303b, 303d rest on the base 302k of the support body 302. If the holding plate 303 lies on the support body 302 in the upper height position h2, the offsets 302a1, 302c1 of the two higher receiving parts 302a, 302c engage in the cutouts 303b1, 303d1 of the holding plate 303. Furthermore, these inserts 303b, 303d rest on raised support surfaces 302a2, 302c2 of the base 302k of the support body 302. This configuration has the advantage that only two web-like inserts are to be formed, each of which can optionally be brought into engagement with a pair of cranked receiving parts. A particularly simple construction results from the fact that below the bends 302a1,302c1 of the higher receiving parts 302a, 302c on the base 302k there are elevated support surfaces 302a2,302c2, the distance between the bends of the higher receiving parts from the associated supporting surface being equal to that Distance of the lower receiving parts to the base 302k of the support body 302 is. In this way it is sufficient if only one pair of cutouts 303b1, 303d1 is provided in the individual inserts 303b, 303d. A support 303e can also be seen in this embodiment, which is supported in the lower height h1 of the holding plate 303 in alignment with the underside of the base 302k of the support body 302 on the upper side 310a of the ski 310 and which is located in the upper height h2 of the holding plate 303 an elevated support surface 302e of the base 302k, which is aligned with the two other support surfaces 302a2, 302c2.

Furthermore, the holding plate 303 has a latching arm 303p which is directed towards the base plate 311a and has a latching lug 303r which engages in a lower latching recess 311c1 in the lower height position h1 and in an upper latching recess 311c2 of the base plate 311a in the upper height position h2 . Both the lower locking recess 311c1 and the upper locking recess 311c2 are bounded on their front side by an inclined surface 311d1 or 311d2 and open on their rear side, the upper locking recess 311c2 of the base plate 311a carrying at least one stop 311e assigned to the locking lug 303r. If two locking lugs 303r are provided on the locking arm 303p, the locking recess 311c2 of the base plate 311a has a stop 311e on its rear side, preferably in a symmetrical arrangement.

In this exemplary embodiment, the latch arm 303p of the holding plate 303 is chamfered on its end face 303p1 and, depending on the height (h1 or h2), interacts with the lower or upper inclined surface 311d1 or 311d2 of the base plate 311a. The lower inclined surface 311d1 serves to secure the holding plate 303 in its lower height position h1 against unintentional shifting or unlatching in the direction of the ski tip. If the holding plate 303 is in the upper height position h2, it is secured against inadvertent displacement or locking by means of the end face 303r1 of the latching lug 303r, which rests against the stop 311e of the base plate 311a, in the direction of the ski end.

The distances between the offset bends 302a1,302b1 and 302c1,302d1, viewed in a projection from above onto the base 302k of the support body 302, are designed in such a way that the holding plate 303 is displaced in the longitudinal direction of the ski after a slight tilting and on the support body 302 in the other altitude h1 or h2 can be brought. The extent of the tilting depends on the design of the component and the component interacting therewith (crosspiece or recess). Analogously, all interact with each other for that Anchor the holding plate to the components provided with corresponding roundings, so that the detachment of the holding plate from the supporting body cannot lead to a corner in either its lower or upper height position h1 or h2.

In the further embodiment according to FIGS. 14 and 15, the sole support plate 401 is equipped with a frame-like support body 402 and with a clip-on holding plate 403, which carries the slide plate 404 fastened in the usual manner on its upper side. Transverse receiving parts 402a to 402d of different depths are provided in the supporting body 402, each of which is formed by a recess in the supporting body 402. The configuration is such that a recess with a smaller depth 402a or 402c is always followed by a recess with a larger depth 402b or 402d. When the sole support plate 401 is in the assembled state, following the base plate 411a, the first recess 402a is formed with a smaller depth. The holding plate 403 in this case has three inserts 403a, 403b, 403d and a support section 403e as counterparts, only the first insert 403a having the depth corresponding to the receiving part 402a. The further inserts 403b, 403d are designed correspondingly to the receiving parts 402b and 402d with a greater depth. The support part 403e of the holding plate 403 lying in the direction of the shoe lies on a support 402e of the supporting body 402 in every height position of the holding plate 403.

As a result of this configuration, the holding plate 403 lies on the support body 402 in its lower height position h1, leaving the space in the region of the receiving part 402c free. The first insert 403a and the further inserts 403b, 403d are matched to one another such that when the holding plate 403 is in the upper height position h2, the insert 403a resting on the upper side of the supporting body 402 has a horizontal course of the upper side of the holding plate 403 with the Guaranteed sliding plate 404. If a certain inclination of the upper side of the holding plate 403 appears to be expedient, be it in the lower or in the upper height position h1 or h2, the cutouts in the supporting body 402 or the inserts of the holding plate 403 as well as the mutually cooperating supports 402e or .403e have a corresponding inclination. The design itself lies in the skill of the average specialist.

In this case too, the holding plate 403, similar to the first embodiment, is extended to the front and has at least one latching arm 403p, which carries a latch 403p1, which can be latched in a latching recess 411d of the base plate 411a in both height positions of the holding plate 403 and the latter holds secured against shifting in the horizontal plane.

To secure the holding plate 403 on the supporting body 402 against lifting upwards, at least the rear pair of inserts 403d are each designed as a snap connection and, in the assembled state of the sole support plate 401, cooperate with counter surfaces of the receiving parts 402d or 402c. Although such snap connections are known per se, the snap connection just described is shown on an enlarged scale in FIG. 15a. If all inserts 403a, 403b, 403d and all receiving parts 402a to 402d are designed as snap connections, then a separate securing of the holding plate 403 with one or two locking parts can also be dispensed with. This results in a further advantage in the overall structure of the sole support plate 401.

The invention is not restricted to the embodiments shown and described. Further modifications are conceivable that are well within the scope of the invention. For example, it is conceivable to use the holder or support described in one embodiment also in another embodiment. Furthermore, in the embodiment according to FIGS. 8 and 9, the holding plate 203 can be moved from one height position to the other by means of lifting and moving the holding plate 203 by using a screwdriver, provided that the securing of the holding plate 203 on the support body 202 is not effected by snap locks but by an effective lock in the ski direction. Such a lock is designed according to the invention in such a way that an elastic snap mechanism, for example a spring catch, engages in a latching recess in the support body 202. The arrangement is such that a tool, for example a screwdriver, can be carried out from the other side of the support body 202 and used to release this snap mechanism. In the present exemplary embodiment, the existing openings in the circumference of the receiving part 202c are suitable for this purpose.
