Abstract

(57) [Summary] [Purpose] The buckle of a ski boot has a structure in which the tightening ring does not easily come off during tightening and loosening with the lever. [Structure] A plate 10 comprises a main plate 12 and an auxiliary plate 15 made of an elastic plastic fixed to the main plate 12, and has a corresponding number of teeth 13 and 17, respectively. An inlet 22 is defined. The tooth 17 has a bevel 23 which limits the depression 21. In order to insert the ring 9 into the recess 21 through the narrow inlet 22, the ring 9 is pushed strongly and the teeth 17 are bent and inserted. The ring 9 placed in the recess 21 cannot easily come off because the teeth 17 return elastically.

[Industrial applications]

 The present invention relates to a device, commonly referred to as a buckle, for fastening two open parts of a boot of a ski boot, and more particularly to an L-shaped tooth of a plate provided on one part of the boot. The device is of a type in which the ring is hooked and tightened with a lever.

[0002]

[Problems to be solved by conventional techniques and devices]

 For example, the device disclosed in U.S. Pat. No. 4,051,611 is designed to be secured by locking a rectangular ring with a lever to the L-shaped teeth of the plate and tightening. Such buckles are widely used in conventional ski shoes of the type that is fastened with four buckles.

By the way, for skiing, it is necessary to firmly tighten the foot with a buckle and hold it firmly with a ski boot, and after the skiing, the skier wants to loosen the bag and relax the foot. I often feel. In this case, most skiers operate one or two levers to loosen the buckle.

However, during the operation of loosening the buckle, the ring is easily disengaged from the teeth of the plate, so that it is not in a state suitable for skiing, and the skier tries various optimum fastening positions before the next skiing. Will have to try. In U.S. Pat. No. 5,136,794, an annular shaft is provided in the lower part of the open part of the boot part and a ring made of a single wire is passed through it to tighten the two parts of the boot part at the same time. It is raised so that the condition for gliding and the relaxed condition for walking can be created simply by raising and lowering the lever. In this example, the operation is simple, but the fact that the wire ring easily disengages from the plate teeth when the lever is raised has not been solved.

[0005] Thus, for example, as described in Swiss patent CH1-749 / 93, the buckle can be loosened or closed properly only by raising and lowering the lever, and a ring for tightening during operation can be provided. There was a desire for a device that closes the boots of ski boots that are hard to come off. The present invention has been made in view of such problems.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a device for closing a boot of a boot according to the present invention has a lever pivotally supported on one part of the boot and a lock fixed on the other part of the boot. Plate and a ring for hanging between the plate and the lever, and the ring is locked to any one of a plurality of teeth having an L-shaped cross section, which are included in the plate. In a closing device for a boot portion of a ski shoe that closes a part, the plate includes a main plate and an elastic plastic auxiliary plate fixed to the main plate, and the auxiliary plate is a tooth of the main plate. A configuration having at least one row of corresponding teeth, defining a recess and a narrow inlet by these two teeth, allowing the teeth of the auxiliary plate to flex and allowing the ring to be inserted and removed. Those were.

In addition, according to another aspect of the present invention, there is provided a boot boot closing device for a ski boot, wherein the main plate has at least one gap extending in the longitudinal direction so as to divide the above teeth, and the teeth of the auxiliary plate are It can be configured to be fitted in a gap in the longitudinal direction.

In addition, the closing device for the boot portion of the ski boot according to the present invention may be configured such that the tooth portion of the auxiliary plate is connected to the base.

Further, the device for closing a boot portion of a ski boot according to the present invention may be configured such that the teeth of the auxiliary plate have a slope portion that limits the depression.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a horizontal sectional view of a ski shoe at a buckle portion, and FIG. 2 is an exploded perspective view of two plates.

A base plate 2 is provided on the outer side of the boot portion 1, and a cover 3 attached to the base plate 2 is provided with a lever 5 rotatably around a center 4. The lever 5 has an attachment piece 7 screwed thereto so as to be rotatable about a center 6, and an elongated ring 9 is attached so as to be rotatable via a connecting member 8. The ring 9 has a substantially rectangular shape so that it can be hooked on the plate 10 fixed to the center of the rivet 11 which penetrates the mating portion of the boot portion.

The plate 10 includes a main plate 12 and an auxiliary plate 15, and the main plate 12 includes a plurality of teeth 13 having a known L-shaped cross-sectional shape. Further, the main plate 12 is provided with a gap 14 extending in the longitudinal direction so as to divide the center of each tooth 13. The auxiliary plate 15 is made of a plastic material and has a curved base 16 corresponding to the curvature of the main plate 12 and a number of teeth 17 equal to the teeth 13 of the main plate 12. The teeth 17 are made slightly thinner than the gap 14 of the main plate 12 so that the gap 17 faces the space between the teeth 13. Further, the tooth 17 has a thin connecting portion to the base 16, and its elasticity makes it easy to bend.

Further, a hole 18 is provided at one end of the auxiliary plate 15, and the hole 18 is used to fix the auxiliary plate 15 to the main plate 12 with the rivet 11. The other end of the auxiliary plate 15 is provided with a rectangular thick portion 19, which is hooked in a correspondingly shaped locking portion 20 of the main plate 12 to support the main plate 12 as an auxiliary plate. 15 is positioned.

When the plate 10 is assembled as shown in FIG. 1, the teeth 17 of the auxiliary plate 15 that have entered the gaps 14 of the main plate 12 have substantially the same height as the teeth 13 of the main plate 12, The recess 21 and the narrow inlet 22 are formed between the mating teeth 13 at substantially equal intervals. Also, as can be seen from FIG. 1, the ring 9 can be positioned in various positions in the recess 21, but in order to insert the ring 9 into the recess 21 through the narrow inlet 22, the ring 9 is pushed strongly at the inlet 22 to provide the teeth 17. It is necessary to insert it while bending it.

At this time, the teeth 17 elastically bend as described above, and serve to firmly stop the ring 9 that has entered the recess 21. Even if the lever 5 is opened, the ring 9 cannot be removed from the depression 21 because the depression 21 is steeply inclined. To remove the ring 9 from the recess 21 to make it free, apply a strong force to the plate 10 by pressing the ring 9 with the lever 5 so that the teeth 17 elastically bend and expand the entrance 22. There is a need . Therefore, in order to make it easier to move the ring 9 in the direction of the rivet 11, the side surface 23 of the tooth 17 forming the depression 21 is made an inclined surface, and when the auxiliary plate 15 is bent, the height of the tooth 17 is the tooth of the main plate 12. The tips of the teeth of the auxiliary plate 15 are rounded so as to be lower than the height of 13.

The gap 14 of the main plate 12 and the row of the teeth 17 of the auxiliary plate 15 may be provided in plural, or the auxiliary plate 15 may sandwich the main plate 12 from both sides.
