Definitions
- the invention relates to a ski boot, in particular with a rear entrance, and an essentially closed front boot.
- ski boots with an overlapping cuff there is the possibility, at least within certain limits, of individually “strapping" the foot against the boot, possibly also in the area of the various buckles. The force is always exerted from above.
- Pressure distribution plates are provided, which press on the instep or the arch of the foot from above and hold the foot down or at an angle to the rear.
- the bracing is more along a line here. Similar to the overlap models, there is very often pressure pain on the instep or tendon of the foot, which in turn causes considerable pain.
- the arch of the foot is pushed through, which sometimes causes pain and increases the tendency to spread and lower feet.
- the invention has for its object to provide a ski boot that creates a better frictional connection and still make it possible or easier to bend the foot.
- a ski boot in particular with a rear entrance and a substantially closed front boot, with a quick-release fastener (which can also be operated via a Bowden cable) to bring about the frictional connection between the foot and the ski boot, with a pressure distribution plate via which the pressing process can be brought about, the Pressure distribution plate is divided and adjustable in the lower front area overlapping via elongated hole and rivet guide by acting on a Bowden cable, the overlap of the pressure distribution plate is brought about in its upper area and is possibly only held by a rivet.
- a quick-release fastener which can also be operated via a Bowden cable
- WO85 / 03416 WO85 / 034166
- a height-adjustable sole is provided by shifting weight in the boot via a tilting cam.
- the skier should tension a cable connected to the adjustable base plate even when a special force connection between the foot and skin is necessary. It remains to be seen whether such a solution is realistic or has ever been implemented.
- a divided pressure distribution plate is not provided in any case, and the lifting and lowering of the base plate is not brought about by a quick-release mechanism to bring about the frictional connection between the foot and the ski boot.
- WO85 / 03416 relates to the special case that the pressure on the foot and the seat is to be increased and in only during the advance (swinging) and lifting normal driving position should return to the released state.
- Adjustment of the sole is known in FR-A-21 80 316.
- a cam is adjusted between two positions using a lever screw. A different effect than with the known parts to improve the template in the ski boot is not achieved.
- the divided pressure distribution plate is preferably articulated on the underpass via articulated rivets.
- a rivet of one pressure distribution plate half can be freely movable in a transverse slot of the other pressure distribution plate half.
- the divided pressure distribution plate is preferably guided on the outside over a particularly fixed instep part of the shoe.
- Günsitg is to act on the pressure distribution plate on a joint by means of a single Bowden cable with a spring spiral.
- the dimension frame according to the invention not only solves the above problem but also brings a whole range of other advantages with it.
- ski boots The invention is described on the basis of ski boots. It can of course be used on mountaineering ski boots, mountain boots or ice skating boots.
- the invention is not limited to the constructions described below. Mechanical solutions using toggle levers, tension anchors or the like are of course possible.
- the solution according to the invention is applicable to shoes with a wide variety of floor space, as is clear to a person skilled in the art due to the large adjustment stroke.
- the toe area can be raised separately for more expensive models.
- the measure according to the invention gives the adjustment range up to 2 cm heel lift height.
- the measure according to the invention is not pressed linearly or point-wise onto the foot: rather, the entire surface of the foot receives a considerable surface pressure due to the uniform application of the sole of the foot.
- the inside of the shoe can be adapted or shaped to the foot, in particular by lifting a deformable sole against the unloaded foot.
- the measure according to the invention is particularly advantageous if the power transmission (for lifting the sole of the foot in the heel and / or in the toe area) takes place via at least one Bowden cable.
- the lifting device consists of two otherwise symmetrical triangular plates fixed to a base plate with the longest side, which is slidably mounted with a central transverse bolt in a vertical slot of a sliding block of triangular shape fixed to the ski sole, similar to that of the triangular plate.
- Cylindrical cross bolts fixed to the Bowden cable grip the triangular plate; the displacement takes place via the cross bolt sliding within the slot of the sliding block.
- the sliding block can expediently be stepped on its free legs, with a free cross bolt assigned to the respective free leg being fixed on the Bowden cable, each sliding in train in the next rest stage of the triangular plate.
- At least one eccentric loaded with a Bowden cable can be provided for quickly raising and lowering the base plate.
- the eccentric can also be formed on a cross shaft under the base plate.
- a particular focus of the invention is the combination with pivot bearings of the cuffs of the ski boot that are freely movable in elongated holes relative to the shell.
- Another combination results from the pressurization of the known pressure (distributor) plate in the area above the instep. It is particularly interesting if the pressure is also applied via a Bowden cable and quick release.
- both the Bowden cable for the base plate to be lifted and the Bowden cable for loading the pressure plate can be inserted into a single quick-release fastener and can be individually adjusted using a knurled fine-adjustment screw.
- the pressure plate can be acted upon by spring steel strips articulated in the area of the pivot bearings;
- the overlapping upper spring band can be tensioned via the bow pull. This construction also avoids the previous line pressure. This results in an application over the entire area of the printing plate.
- the pressure plate can of course be individually designed for the foot, for example by molding it separately on the foot and only then installing it in the ski boot.
- the common quick-release fastener is a rocker-lock fastener.
- the measure according to the invention gives rise to a whole series of further possibilities: one can be seen in a deformable foot insert on the sole plate which is adapted to the individual foot shape.
- cushion pieces can be attached, which are able to reduce the distance between the outer skin of the inner shoe and the inside of the shell.
- the upholstery pieces can consist of heat-insulating materials.
- Thermoplastic deformable inserts can be inserted over the inner shoe, which fill the space between the inner shoe and the shell after curing.
- FIG. 1 to 4 and 7, 8 and 9 are not an exemplary embodiment of the invention.
- a part of the lifting device consisting of two otherwise symmetrical triangular plates 12, each with the longest side fixed to the base plate, is provided on a base plate 10 made of plastic, for example, which has a central transverse bolt 14 in a vertical slot 16 on the ski shoe sole solid sliding block 18 triangular shape similar to that of the triangular plate 12 is slidably mounted.
- the tip of the equilateral triangle is blunted.
- Cylindrical cross bolts 20, which will be described later, are provided. Two such cylinder bolts 20 are provided. The raised position can be seen through the dashed position at 20 '.
- the longitudinal course of the slot 16 of FIG. 2 is only indicated in FIG. 1.
- Fig. 2 shows the on the ski boot sole, for example, screws 22 fixed sliding blocks 18 also equilateral triangular shape.
- the vertical slot 16 is formed by the tip, which lies opposite the long side of the triangle (on the ski sole side), in which the transverse bolt 14 guided in the triangular cheeks slides when assembled.
- latching shoulders 24, 26 are provided on the same sides of the sliding block, in which they support the transverse bolts.
- the cross bolts are firmly blocked with the Bowden cable only indicated here.
- the Bowden cable is of course carried out under the cross pin 14.
- the sliding block 18 has a continuous vertical milling 28 at the top perpendicular to the slot 16. If the sliding block is most interesting in one piece because of its durability, it is a central deep milling 28, whereby cheeks 18 ', 18' of the sliding block are formed.
- Fig. 4 shows an assembly example in the view, Fig. 3 in the bottom view.
- Fig. 4 clearly shows the possible stroke. If the triangular plate 12 is lifted by the Bowden cable (not shown here), the base plate 10 is raised in the same way, and the foot is pressed against the inner shell (bottom step) of the ski boot. 3 (the sole of the ski boot is not shown; only the two fastening screws are indicated), one can see the continuous wedge-shaped cheeks 30 with which the base plate 10 is supported, the triangular plates 12, the longitudinal slot 28, etc.
- the sliding block is guided within the triangular plate, ie raised and lowered by the quick release.
- the quick release fastener is shown in the closed state in FIG. 5.
- the Bowden cable 32 runs in the clamp closure of the cross bolts 20 (or in the elevated position from the cross bolts 20 'coming).
- the direction of actuation of the quick fastener is indicated at 34.
- the quick release fastener which is attached to the rear shaft of the ski boot 36, is closed.
- the housing 38 of the quick release fastener is pivoted about the axis 40.
- the course of the Bowden cable 32 takes place in grooves of a cylinder body 44 pivoting about the axis 40.
- the Bowden cables are then guided into the interior of the housing 38, as indicated by the broken line at 32, and fastened there.
- the quick-release fastener as a whole can be tensioned or regulated via an adjusting anchor 46 and a common adjusting screw 48.
- two such Bowden cables are provided, one of which is connected to the pressure plate, the other, as said, to the cross bolts on the sliding block.
- the Bowden cables can also be tensioned against spring preload.
- Anchor and knurled screw are also stored in the housing of the quick release.
- the quick release can also be replaced by a simple rocker arm, which is secured at the bottom, for example.
- the holes for swivel bearings can be seen for pivoting the moving parts against the fixed parts of the ski boot. A particularly preferred embodiment will be described with reference to FIG. 7.
- the Bowden cables can be set individually with regard to their pretensioning force via adjusting screws 52, 54.
- Fig. 6 shows the quick release fastener with a view of the back of the ski boot.
- the same reference numerals designate the same parts as in FIG. 5.
- Knurled screws attached in the area of the reference numerals 32, 32, which allow an individual adjustment of the allow two Bowden cables 32.
- the knurled screws are housed in a separate housing, not shown. After leaving the rear cuff, the two Bowden cables then go into the interior of the lower step, ie into the image plane of FIG. 6, as can be seen in FIG. 5.
- Fig. 7 illustrates how when pulling the Bowden cable 32, the cylinder bolts 20 move up the sliding block 18, while the transverse bolt 14 lifts in the slot 16 of the sliding block.
- recesses, depressions, etc. are formed in the area of the ski sole S.
- a very particularly preferred combination of the measure according to the invention results from the slot or the elongated hole 50 in the shell or the underside of the ski boot.
- this elongated holes provided on one side or even better on both sides of the lower part or the shell, the respective pivot bearing of the cuff part or parts of the shoe can move freely relative to the shell.
- the foot automatically adjusts itself anatomically to the ski boot.
- the asymmetrically designed calf is firmly held in the ski boot shaft.
- this is more precise in the related application P ... described by the same day.
- the paragraphs of the sliding block, on which the bolts are pulled, are only hinted at.
- a return spring is not necessary, since when the quick-release fastener is released either by the weight of the base plate, but essentially by the pressure of the sole of the foot on the base plate, which is pressed down against the sole of the ski boot.
- Such a return spring is additionally provided according to a preferred embodiment.
- FIGS. 8 and 9. These are tension straps.
- the tensioning strap 60 is articulated with its eye 62 to the pivot bearing (for example 50 in FIG. 6).
- the above-mentioned second Bowden cable is pulled through the eyelets 64.
- a rivet head of the strap guide of FIG. 9 can be seen.
- the rivet head 68 is firmly attached to the other spring band.
- the distance from head to head of the rivet is so great that the overlapping spring band rail is guided through the continuous rivet in the slot of FIG. 9.
- the spring band 60 rests elastically around the pressure plate known per se in the area of the instep / bend on the inside of the shell.
- Fig. 9 shows the counterpart mentioned.
- This spring band is mounted with its eye 70 on the other pivot bearing and has the slot 72 in which the rivet 68 can slide.
- the Bowden cable 32 is indicated by dashed lines in FIG. 8, which is guided through the eyelet 64-64, but of course also through the end eyelet 74 of FIG. 9.
- the Bowden cable is secured, for example, by a cross bolt, which can be adjustable as a screw bolt.
- FIG. 10 shows a scissor-like overlapping, that is to say divided, cuff-like pressure distribution plate or instep plate 86 with cutouts (weight saving), which is fastened on both sides to the inside of the shell (bottom step). This is preferably done on the rivets.
- a rivet 88 of one pressure distributor plate half is guided in the transverse slot 90 of the other pressure distributor plate half in a freely movable manner. The halves overlap at the top and are (deliberately) not connected in order to make bending easier or easier.
- a Bowden cable 92 with a spring spiral acts on the pressure distribution plate, which is seated on the joint 94.
- FIG. 11 shows, in an embodiment similar to that described above, a swivel lever 100 which is mounted on the top of the rear of the ski boot and is locked in the closed position by a bolt 102. If you press the lever on the top in the direction of 104, the swivel lever is opened, the sole is immediately lowered and the foot is relieved, which can mean a significant advantage when skiing, but above all when skiing. Other locking options are also possible.
- the pivot lever 110 is in its tensioned position, which means that a lever end 112 points downward.
- a spring-loaded latch 114 secures the end.
- the locking lug is displaceable and pivotably mounted about its counterpart 116, which is fixed on the ski boot, in the bearing 118. Again, you can press the latch with the ski stick to open it. Only a Bowden cable would be required here.
- FIG. 13 A further modification to FIG. 7 is shown in FIG. 13.
- Artificial damping in the form of a spring 120 is now attached to the end of the Bowden cable 32. This has the advantage that even with a relatively loose assignment of sliding block to triangular plates, the transverse bolts 20 fixed to the Bowden cable cannot wedge. In addition, elastic damping is brought about, so that particularly strong blows to the ski, which can occur, for example, when driving rapidly over icy slopes, are alleviated.
- the spring 120 is held on the Bowden cable 32 via an end piece 122.
- ski boot After a modification, not shown, it is also possible to construct a completely different kind of ski boot.
- a type of pressure distributor plate (but without openings) is guided over the fixed instep part or a relatively stiff sleeve, which is otherwise similar to the pressure distributor plate of FIG. 10. The pressure is therefore exerted on the ski boot from the outside.
- This modification or the embodiment form of FIG. 10 help to make the rear entry shoe suitable for racers, racers who previously rejected rear entry models because of the emotionally missing connection from foot to instep part of the shoe.
- the insole can be shaped (method known per se) in such a way that the sole is molded onto the shoe from below by lifting the sole from below .
- the molding process itself can be carried out according to known techniques.
- the measure according to the invention as a whole combines the advantages of the previous overlap system with the advantages of a rear or central entry model. Also, the outer shell no longer has to be made as thick, especially not as stiff as before.
