Definitions

  • the invention relates to a ski boot buckle for closing the shell of a ski boot, as well as a ski boot equipped with this ski boot buckle, as specified in claims 1 and 13.
  • a ski boot buckle which comprises a tooth plate, a bracket, a connecting piece and a lever which is mounted in a lever holder and can be held by means of a spring element with a predetermined holding force in its open position.
  • the tooth plate is formed so that the bracket can hook in both the pulling and pressing direction, wherein the bracket makes with the connector a rotatable connection with the lever, attach to the tooth plate and can apply a thrust to the Press on shoe shell.
  • a hold-open position of the buckle is in this case realized in that said spring element is designed as a spring tongue which is attached to the lever holder.
  • This spring tongue on the lever holder acts on the lever in such a way that when a certain pivoting angle position is exceeded, an automatic tilting back of the lever into the closed position is prevented.
  • the lever has a contoured or cam-like shape in its end portion closest to the lever holder, on which end portion the spring element acts, the lever can be fixed in its open position by means of the spring tongue with limited holding force that can be overcome by hand.
  • the lever To close the buckle, the lever must be pushed in the direction of its closed position, the lever displacing the spring tongue, the strap is tensioned, the tooth plate pulls on and thus increases the overlap between the first and further shoe flap, so that the receiving volume the shoe cup is reduced.
  • the lever - As is known - held in its closed position and the ski boot buckle remains closed with the corresponding desired tensile or clamping force.
  • the EP 2 198 730 A1 describes a ski boot buckle consisting of a tooth plate, a bracket, a connector and a lever which is pivotally mounted in a lever mount. On this lever, a ring or bow-shaped retaining element is attached.
  • the tooth plate is designed so that the bracket can hook in both the pulling and in the pushing direction, so that the bracket can exert both tensile and shear forces on the tooth plate.
  • a hold-open position of the buckle is in this case realized in that the annular or bow-shaped retaining element engages behind an undercut or groove on the lever mount or positively engages therein, whereby the lever is fixed in its open position.
  • the lever In order to close the buckle, the lever must first be opened a little further to manually release the retaining element from its locking position relative to the undercut on the lever bracket. In particular, the lever must be swung over its hold-open position in order to cancel the positive engagement with the lever bracket can.
  • the in the AT 506 481 B1 described embodiment has the disadvantage that there is a potential danger point by the specified arrangement of the spring element and by their execution as a spring tongue.
  • there is an increased risk of injury to the operator since the operator can pinch his fingers between the spring element and the lever holder during the closing or opening process of the ski boot buckle, or can come to the spring tongue.
  • the in the EP 2 198 730 A1 described embodiment has the disadvantage that another component in the form of a ring-shaped or bow-shaped retaining element is necessary to fix the operating lever when needed.
  • the use of this retention element increases the complexity of the buckle, making it vulnerable to ailments.
  • the ease of operation of the buckle can no longer be guaranteed in accordance with a conventional ski boot buckle, since the buckle requires the retaining element to be manually moved from its engaged position to close the buckle.
  • an additional operating action is necessary for the person who wants to put on or take off the ski boot.
  • the retaining element can be disturbing, especially when operating the ski boot buckle with ski gloves or can be very difficult to operate with gloves.
  • the present invention has for its object to provide a ski boot buckle, which can remain in the open position during the donning or pulling out of the ski boot or during use of the ski boot or is not engaged with the toothed plate, the corresponding design produced as inexpensively should be and still provide a high level of ease of use.
  • a ski boot for increased comfort and functional requirements to create.
  • a ski boot buckle for closing the shell of a ski boot which comprises a tooth plate for mounting on a first tab of the shell of the ski boot, and a lever system for mounting on another tab of the shell of the ski boot.
  • a bracket is rotatably connected to an operating lever, wherein the operating lever is rotatably received in a lever holder.
  • at least one spring element for transferring the actuating lever into a closed position is arranged in the lever system.
  • another spring element is arranged or formed, by which further spring element of the actuating lever respectively the ski boot buckle in the open position is halterbar.
  • An advantage of the design according to the invention is that the positioning of the further spring element directly on the operating lever, the ski boot buckle can be configured so that as possible no danger spot arises at which a user of the ski boot may contract a pinch or injury.
  • the corresponding spring element can be designed as simple as possible in constructive view, so that it is inexpensive to manufacture and can be optimally mounted on the operating lever or even executed as an integral part of the operating lever.
  • no additional manipulation of the user's side is required for the closing operation of the ski boot buckle, starting from its hold-open position, but the ski boot buckle can simply be pushed shut like a conventional ski boot buckle. This ensures that handling is as simple as possible and the ski boot is easy to put on or take off again.
  • ski boot buckle when wearing gloves, as often occurs in the course of the use of ski boots, a comfortable as possible and effortless operation or operation of the ski boot buckle can be ensured.
  • the ski boot buckle according to the invention or the ski boot equipped therewith avoid spring elements which by their shape or positioning represent potential danger spots during the closing process or during the opening process of the ski boot buckle.
  • the further spring element can be displaced into or out of engagement or into and out of spring-elastic interaction by pivoting the actuating lever into or over a predetermined pivoting angle position with the lever holder.
  • the advantage here is that the operating lever can be operated the same as in a conventional ski boot buckle without additional operations are required.
  • the spring element is in the closed position of the ski boot buckle not or only marginally with the lever holder in engagement or in interaction and the spring element is thus not biased or hardly loaded.
  • the operating lever of the ski boot buckle is pivoted beyond a predetermined pivoting angle position or opened, presses the other spring element, the actuating lever in the open position and thereby the actuating lever is held resiliently, whereby the actuating lever can remain in this open position.
  • the operating lever must simply be manually moved to its closed position or urged. If it is again pivoted beyond a certain pivot angle position or moved there, it can be provided that the further spring element urges the actuating lever into the closed position or presses.
  • the further spring element is formed by an elastically resilient cam, which is formed eccentrically to a pivot axis of the actuating lever and is formed in an end portion of the actuating lever facing away from an actuating portion of the actuating lever.
  • an open position of the ski boot buckle be taken or activated by the user of the ski boot, which open position allows the widest possible volume expansion or circumferential expansion of the ski boot without the user completely loses hold in the ski boot.
  • the ski boot buckle or its bow can be adjusted to the maximum opening width with respect to the toothed bar and at the same time the open position of the ski boot buckle or the actuating lever be taken, whereby the user still experiences a limitation or a certain retention, especially when used in the cuff area of the ski boot.
  • the further spring element is U-shaped in cross-section and includes a first and second legs, with which the further spring element is mounted on the actuating lever, wherein a connecting the two legs base portion with respect to one of Actuating portion of the actuating lever facing away lever arm of the actuating lever is formed protruding.
  • a U-shaped spring element may be provided, which is mounted on the actuating lever and thus can ensure that the actuating lever remains in its open position. It is advantageous in the construction of the further spring element in a U-shaped configuration that the further spring element partially surrounds the actuating lever, whereby the power transmission from the further spring element can be realized on the actuating lever relatively optimal by positive locking. In addition, a high longevity of the further spring element can be achieved because it has no high-stress points.
  • the base portion forms an arcuate contact surface which can be brought into and out of contact with the lever holder. It is advantageous in an arcuate contact surface, that the wear which occurs on the lever holder due to relative movements between the base portion of the further spring element and the lever holder, can be minimized, since there are no sharp edges. Consequently, a long-term as constant as possible functional behavior of the ski boot buckle can be achieved.
  • the contact surface protrudes from 2 to 10 mm, in particular from 3 to 6 mm, preferably 4 to 5 mm with respect to the lever arm.
  • an elastic deformation path of the further spring element in the transition between the closed and open position - and vice versa between 0.5 to 4 mm, in particular between 1 to 3 mm, preferably between 1.5 to 2.5 mm is.
  • the actuating lever is connected directly to the bracket or by means of a connecting piece with the bracket, wherein the further spring element is designed as a latching projection, by which the bracket in a spaced apart from the tooth plate, disengaged inactive position is halterbar ,
  • the further spring element can be built very small and relatively optimally integrated in the operating lever.
  • the strap of the ski boot buckle can be kept constantly taking out a raised inactive position relative to the rack bar out of engagement with the rack.
  • the further spring element prevents an intervention of the bracket in the rack.
  • a holding force of the locking projection can be overcome without tools, so that the bracket can be converted by manual operation, starting from its inactive position in an active position contacting the tooth plate - and vice versa -.
  • the holding force of the locking projection is adjusted such that the function of the open position is ensured, the ski boot wearer relative to the operating lever, however, does not have to spend increased forces to close the ski boot buckle.
  • the further spring element defining latching projection is formed by at least one wart-like elevation within the Verschwenkweges between the actuating lever and the bracket or the connecting piece.
  • the further spring element is mounted by means of a connecting bolt between the actuating lever and the bracket or the connecting piece and / or by means of a connecting bolt between the actuating lever and the lever holder on the actuating lever. It is advantageous in this case that these connecting bolts in the ski boot buckle are present anyway and thus no separate fasteners for the further spring element are needed. Conveniently, these connecting bolts can form the pivot axes between the relevant parts.
  • the lever holder made of a first material, preferably metal
  • the further spring element is made of a further material, preferably plastic.
  • the advantage here is that by the execution of the further spring element in plastic, this is easy and inexpensive to produce by a casting process. Furthermore, it can be achieved by the combination of metal and plastic, that even with frequent opening and closing of the ski boot buckle any signs of wear on both parts remain low.
  • the second-mentioned object of the invention is achieved by a ski boot according to claim 13.
  • the technical effects and advantageous effects that can be achieved with this are to be found in the preceding and the following parts of the description.

  • the inner shoe 3 which is made of a soft plastic material, from the shell 2, which made of a comparatively hard and dimensionally stable plastic material is to be taken out.
  • such a ski boot 1 is designed as a touring ski boot, in which case the inner boot 3 is typically designed to be laced.
  • the ski boot 1 can also be designed as alpine ski boot, wherein here the inner boot 3 usually does not have a separate closing or fastening means.
  • the inner shoe 3 is at least partially received or bounded by the shell 2.
  • a foot received by the inner boot 3 can be held in the inner boot 3 by reducing the receiving volume of the shell 2 or of the inner boot 3.
  • the reduction of the receiving volume of the shell 2 is effected by ski boot buckles 4, wherein a different number of ski boot buckles 4 can be arranged on the shell 2 on a ski boot 1, depending on the execution model.
  • the shell 2 comprises a shaft 6 and a lower shell 7, which are connected by means of a hinge joint 5 articulated.
  • two skiboot buckles 4 are each arranged on the lower shell 7 and on the upper 6.
  • a Velcro strip 8 can be arranged on the shaft 6, by means of which a foot received by the ski boot 1 can be additionally stabilized.

  • the ski boot buckle 4 comprises a toothed plate 9, which is mounted on a first tab 10 of the shell 2, for example on a tab of the shaft 6.
  • the toothed plate 9 can in this case be mounted on the first lug 10 via a first fastening means 11, which fastening means 11 can be designed, for example, as a rivet or as a screw.
  • the tooth plate 9 is glued to the first tab 10 or formed thereon.
  • the ski boot buckle 4 further comprises a lever system 12, which is mounted on a further tab 13 of the shell 2, in particular of the shaft 6. Again, it is possible to mount the lever system 12 via a further fastening means 14 on the further tab 13, or to glue or partially inject this into the plastic.
  • the lever system 12 has a bracket 15, which is arranged on a connecting piece 16.
  • the bracket 15 has a pin portion 17 which can engage in a tooth 18 of the tooth plate 9.
  • the bracket 15 may be executed in plan view also T-shaped.
  • the connection between bracket 15 and connector 16 can be performed either rigid or articulated.
  • the connector 16 may be made either in one piece or in several parts.
  • the connecting piece 16 may be divided into a spindle 19 and a shaft 20 receiving the spindle 19.
  • the length of the connecting piece 16 can be adjusted, whereby a fine adjustment of the closing width 21 is possible.
  • the coarse adjustment of the closing width 21 is effected in that the bolt portion 17 of the bracket 15 can engage in various of the teeth 18 of the tooth plate 9 formed one behind the other.
  • the connecting piece 16 is pivotally connected together with the bracket 15 via a first connecting pin 22 with the operating lever 23 of the ski boot buckle 4.
  • the actuating lever 23 is in turn connected via a further connecting pin 24.

  • a further spring element 28 has been attached to the actuating lever 23 by which further spring element 28 of the actuating lever 23 can be held in an open position 29.
  • a desire for increased freedom of movement of the foot or leg of the user can be better taken into account when wearing the ski boot 1 with some ski boot buckles 4 held in the open position 29. This is especially true when the bracket 15 or its bolt portion 17 engages behind one of the teeth 17 or hooked into the rack 9 (in Figure 3 not shown).
  • maximum freedom of movement of the foot or lower leg can thereby be achieved while simultaneously avoiding a complete widening of the straps 10, 13 of the shaft 6, so that the foot does not lose its hold relative to the ski boot 1.
  • the bolt portion 17 can also be brought out of engagement with the teeth 18 by the user, thereby enabling an easy entry or exit relative to the ski boot 1.
  • the actuating lever 23 is located in accordance Fig. 3 in its inactive position 30 from which it can be pivoted into its active position 31 (not shown). In the active position 31, the pin portion 17 is engaged with a tooth 18 of the tooth plate 9.
  • Fig. 3 is also clearly visible that the closing distance 21 in the shaft 6 is greater than the comparison value in the closed ski boot 1, which in Fig. 2 is shown.
  • the assumption of the open position 29 of the actuating lever 23 and the simultaneous taking of the active position 31 of the bracket 15 on the nearest to the lever system 12 tooth 18 of the tooth plate 9 may be advantageous to achieve an increased or maximized receiving volume in the shoe interior, but still an unobstructed expansion or distancing the tabs 11, 13 to prevent.
  • Such a comfort setting can be particularly advantageous for touring ski boots 1. This especially if there is a slight increase or if rest stops are engaged.
