Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a ski binding fixing device.

(Prior art) The binding of conventional skis is fixed by
The binding mounting plate is fixed to the ski wood using screws.

(Problem that the invention aims to solve) Conventionally, the ski wood and binding have been fixed exclusively with screws, so if you fail to drill holes for screw fixation, the ski wood itself becomes unusable. Not only was there a risk, but there were also problems such as restrictions on position correction. In addition, since the mounting plate requires a considerable thickness and area for strength,
There was a problem that the weight of the binding was likely to increase.

(Means for Solving the Problem) However, this invention provides a long groove parallel to the long edge of the ski wood on the surface of the binding fixing part of the ski wood, and a long rod provided at the bottom of the binding in the long groove. By fitting and fixing, the above-mentioned conventional problems were solved.

That is, this invention provides a long groove on the surface of the binding fixing part of the ski wood part, which is parallel to the long edge of the ski wood part and extends from the toe piece attachment position of the binding to the heel piece attachment position, and at both ends of the long groove. forms a dovetail groove with a mouth edge width smaller than the internal width, and the central part of the long groove forms a wide part with a mouth edge width equal to the internal width, and a lower part of the binding is formed at both ends of the long groove. This is a binding fixing device for skis, characterized in that a long rod provided in the ski is inserted and slid to fix the binding. In addition, the long groove is one or more, and the depth is sufficient to fit the long rod of the binding, or the long rod is fixed with adhesive, the long groove and the long rod are fixed by fitting, or a fixture is used. This is a binding fixing device for skis.

The long rod can be fixed with adhesive, or by fitting the long rod into a long groove, and the axial movement of the long rod can be fixed with screws, or with a fixing device (such as an eccentric cam or other pressure tool). Fix the long rod with.

(Function) In this invention, a long groove is provided in the wood of the ski, and the long rod of the binding is inserted and fixed into this long groove, making it easy to make fine adjustments during the fixing work. Because there is no) there is almost no. In addition, in order to secure the fit between the long rod and the long groove,
The resistance to rotation or twisting on the binding is large.

(Example 1) Examples of this invention are shown in Figures 1, 2, and 4.
This will be explained based on the diagram.

Long grooves 2, 2a parallel to the long edges of the ski wood part 1 are bored at predetermined intervals on the binding attachment surface of the ski wood part 1. Next, the toe piece 3 of the front and rear binding, the long rod 4 provided at the bottom of the heel piece 3a,
4a into the long grooves 2, 2a, and
A jamb 5 is inserted into the end of the groove 2, and a retaining piece 6 is fixed with a screw 7 to the center of the long grooves 2, 2a. In this way, the long rods 4, 4a are prevented from moving laterally by the jambs 5 and the retaining pieces 6, and because the cross section of the fitting portion of the long grooves 2, 2a is a dovetail groove, they are prevented from coming off upward. Since this is not possible, it can be fixed securely.

In the above, in order to fix the toe piece 3 and heel piece 3a of the binding, first, the long rod 4 of the toe piece 3 of the binding is set in the wide part A (wide part) where the mouth width of the long groove is equal to the internal width. It fits in and moves in the direction of arrow 13. In this case, the binding fixing position is calculated and the jambs 5 are fitted in advance. The long grooves 2 and 2a have a dovetail groove in section B (dovetail groove) with a mouth edge width smaller than the internal width, so if they are fitted as shown in Figure 4, it will fit as shown by arrow 1.
There is no risk of it slipping out in direction 4.

Next, by inserting the stopper piece 6 into the long groove and confirming the position of the binding, screwing in the screw 7 completes the fixing of the toe piece 3 of the binding. Next, the heel piece 3a of the binding is also fitted with a jamb in the same manner as above, and then the long rod 4a is inserted.
At part A, move to part B as shown by arrow 15, check the binding position, then insert stopper 6 into the long groove, and then screw in screw 7.
Fixation of the heel piece 3a of the binding can now be completed.

As mentioned above, since the long grooves are provided in advance in the wood of the ski, attaching the bindings 3 and 3a is extremely easy and requires determining the dimensions of the jambs 5 and screwing in the screws 7. It has the characteristic that even unskilled workers can work reliably and in a short time. In the figure, 16 is a binding support shaft, and 17 is a connecting piece between the long rods 4, 4a and the binding support shaft. If there is only one long rod, the connecting piece will be unnecessary.

(Embodiment 2) Next, in the embodiment shown in FIG. 5, a rail 9 is fitted into an outer groove 8 having a rounded cross section, and a long rod is fitted into a long groove 9a inside the rail 9. If the rail 9 is made of synthetic resin or metal (for example, hard aluminum), the dimensional accuracy is good and the fixed state can be ensured.

Although the above embodiment has been described with reference to the case where there is one outer groove 8, there is no problem even if there are two outer grooves.

(Example 3) The example shown in FIG. 3 is the same as in Example 1 above.
Glue 1 to the long rods 4 and 4a fitted in the long grooves 2 and 2a.
It is fixed at 0. Even in this case,
Stability is better when the jambs 19, 19a are inserted.

(Example 4) The embodiment shown in FIG. 6 uses deformed long grooves 11, 11a in place of the long grooves 2, 2a of the ski tree part 1 shown in FIG. Long rod 1
8,18a. In the case of this long groove, the binding insertion part A of the long grooves 11 and 11a has a wide part 1 only on the outside as shown in FIG.
2, 12a should be provided. In this case as well, the use of wood jambs, stoppers, and screws, or the use of adhesives is the same.

(Effects of the invention) That is, according to this invention, the long rods of the binding are inserted and fixed into the dovetail grooves of the long grooves provided in the ski wood, so there is no risk of the binding coming off upwards, and rotation or twisting of the binding is prevented. The binding is firmly fixed to the ski. Furthermore, since the long groove has a dovetail groove portion and a wide portion, and the long rod is inserted and slid within the long groove, the binding is extremely easy to fix, and fine adjustments and corrections are also facilitated.

In addition, by appropriately utilizing this structure, the binding attachment portion can be made lightweight.
