APPLICATION FOR MOUNTING A SKI SHOE IN A SKI

The invention relates to a bandage assembly for attaching a ski boot to a ski, wherein the lower surface of the ski boot has two spaced apart boom length beams provided with transverse holes and secured to the ski by means of pivotable lugs. in the locking position, the bandage is located in the space between the platform beams.

It is known in the art as a binding solution that the lower surface of the ski shoe is spaced from each other by two longitudinal elevation beams which are substantially joined by a visible metal cross bar located at the front edge of the shoe. Similarly, the binding web attached to the ski has a groove into which the transverse rod is fitted. In addition, the groove is provided with a device for closing the 15 grooves, which also locks the rod into the groove.

The disadvantage of such a bandage arrangement is that the transverse rod is relatively short, whereby it is · · '. and the corresponding groove in the bandage are subjected to high lateral forces. In the sole of the shoe, the bar between the bars causes the snow to collect adversely on the bottom of the shoe • »!" '. 20 is critical to attaching the bandage. it is difficult to remove itself, and the shoe will not be fastened unless the sole of the shoe is>> cleaned.

> ♦ «·. · · ·. Another disadvantage of the dressing arrangement described above is that the transverse bar is located in the structure at the front of the old shoe, whereby the heel of the shoe rises too easily from the ski. In the traditional

in skiing skis, this causes black toes. • »*! 'Gaze transfers to the skis only a straightforward force. There is little torque on the ski because the rod in the shoe is able to rotate relatively freely in the groove of the bandage. By kick * M I | thus, it is not possible to influence the location of the grip area at the bottom of the ski.

The bandage arrangement according to the invention provides decisive advantages over the prior art described above. The invention is characterized in that, for locking said pins into respective holes, the bandage means preferably comprises a locking / unlocking portion movable from the front of the bandage via a safety arrangement comprising an oblique surface whose pin can be pushed out of the bandage into the hole in the platform. part can be locked in the hole.

Other features of the invention are set forth in the dependent claims.

An advantage of the invention is that the shape of the sole of the shoe is clear, whereupon it collects poorly snow and leaves snow quite easily. The binder mechanism is completely under the ski boot when the binder is attached. When the ski boot is pushed into the binder, any snow on the sole of the shoe is pushed backwards. Thus, the sole of the shoe does not even have to be cleaned. In all situations, a continuous lateral support is provided between the shoe and the ski, and the shoe also provides torque to the ski, since the point of attachment is not at the tip of the shoe but at a distance from it under the shoe. When lifting the heel of the shoe, the skis will develop a torque that will change the pressure areas of the ski sole. This is especially important in the traditional 15 skiing method, where pressure should be applied to the ski compartment and other times during pressure release.

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which: Figure 1 shows a bandage assembly open to receive a shoe viewed from above.

". Figure 2 is a top view of a bandage assembly locked without a shoe.

. ' Figure 3 shows the bottom of the ski shoe seen from below.

Figure 4 is a front view of a ski shoe.

. ·. Fig. 1 is a top view of a bandage assembly attached to a socket 1 comprising a base plate 4 and a bandage means 3,7,9 attached thereto, and a lever device 6 for securing and unlocking the bandage connected to the bandage means 3,7,9.

'**' The bandage means preferably comprises a body plate 3 made of aluminum sheet, the upwardly edged edges of which act as guide surfaces 16 on respective surfaces 17 of the shoe 2. The upwardly directed edges 30 include holes through which pins 7a are guided. The pins 7a have arm portions 7 having khn attachment points 11 to the plate 3. The arms 7 may pivot relative to the attachment points 11. The arms 7 extend over the attachment points 11 to form an angle with the portion of the previous arm. The springs 8 are used to tension the pins 7a outwards.

The movement of the pins 1a is controlled by an hourglass-shaped locking / unlocking member 9 which includes oblique contact surfaces for the arms 7. The part is moved longitudinally along the ski and the pins 7a either protrude through the holes in the plate 3 or retracted.

In position 1, the ski shoe 2 can be brought into the bandage by dissolving it from the back of the bandage until the holes 13 in the protrusions 15 of the sole of the shoe are at pins 7a.

If the pins 7a are slightly outside the rim 16, the shoe will stop at the correct position when the pins ends hit the holes 13. The latch 6 is then locked by pushing it into position 10 of Figure 2 so that the locking / unlocking portion 9 moves backward

The pins 7a are clearly wider and provide a wider attachment than the known solution in which a short rod between the risers is used as a fastening member. Also, the support and guidance of the shoe between the flanks 17 of the platform beams 15 and the flanks 16 of the plate 3 are better than the known solutions, with the support 15 extending from the anchorage point 3 through both the front and rear.

Fig. 3 is a bottom view of the shoe 2. Between the beams 5, a metal plate 14 is preferably attached to the sole of the shoe, the edges of which are turned against the flanks of the beams 15.

The folded edges 17 then form the abutment surfaces of the abrasion-resistant abutment bond • ·! * '. The holes in the plate 14 are similarly reinforced with the corresponding holes in the beams 15. The holes 13 are under the shoe about 20-40 mm from the shoe tip (dimension a).

• · ·,;, the portion below the shoe 2 of the bandage, parts 3, 7,9, 11 may be covered by a thin protective cover,. * ·, Likewise, behind the bandage member may include a support member 10 shown in Figures 1 and 2, adapted to each sole member (Fig. 3) between the beams 15 so as to provide support between the shoe and the s ... also for the heel of the shoe.
