Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a binding device for ski boots that replaces so-called shoelace ties.

Conventionally, various types of tightening devices for ski boots of this type have been proposed as soft constituent materials become harder.

Conventional tightening devices are mainly designed to make it easy to put on and take off shoes in cold weather, and to provide strong tightening by locking the end metal fitting of the belt to the middle stage of the locking lever and pushing the lever down. , a method was used to secure the belt by tightening it all at once.

According to such conventional means, it is necessary to adjust the length of the belt in advance, and the state of tightening can be adjusted by changing the locking position of the end fitting of the belt with respect to the locking lever. However, in order to do this, it is necessary to add a mechanism for adjusting the length of the belt to the tightening device, but the adjustment operation is relatively troublesome, and the operation of the locking lever that tightens the belt all at once is difficult. In particular, when the end metal fitting of the belt is locked near the turning end of the lever, there is a problem in that a considerable amount of force is required to operate the lever.

Furthermore, the tightness of the belt needs to be delicately adjusted depending on the condition of the downhill surface, depending on the thickness of the socks and the edema of the feet.

Therefore, with conventional tightening means, it is necessary to adjust the length and locking position of the belt each time.

The purpose of the present invention is to provide a fastening device that can eliminate the above-mentioned drawbacks, and the configuration of the present invention to achieve this purpose will be explained based on the illustrated embodiment. It is as follows.

FIG. 1 is a side view showing the ski boot equipped with the strap of the present invention, FIG. 2 is a plan view showing the tightening and holding state of the strap of the present invention, and FIG. 3 is a side view of the ski boot equipped with the strap of the present invention. FIG.

A belt 3 with one end attached to one of the joints has locking parts 2 arranged at several intervals at joints such as shell parts of the soft body 1.
and a locking tool 4 attached to the other.

The belt 3 has a notch-shaped tooth row 6 which is machined by punching along the longitudinal direction of the metal plate 5 at the center thereof, and the tooth row 6 is raised in the direction of the mounting end of the belt 3. They are arranged in such a way that they are facing the same direction.

The metal plate 5 except for the tooth row 6 is covered with a plastic material 7 so that the entire body has appropriate flexibility.

In addition to the configuration shown in the drawings, the belt 3 may have a rough structure such as a hole or a recess that has a locking function in place of the tooth row 6 that serves as the locking surface that is locked by the pawl described later on the locking tool 4. A surface structure may be adopted, and the belt 3 may be constructed of plastic material, leather material, etc. without using the metal plate 5, but if the belt 3 is constructed as shown, snow will be interposed between the tooth rows 6. This has the advantage that if ice or ice forms, they can be easily removed.

The locking tool 4 includes a base plate 8 through which the belt 3 is slidably inserted;
A ratchet lever 11 is rotatably mounted on a shaft 10 passed between both upright edges 9 of the board 8, and a lever 12 is used for tightening.
It consists of.

The ratchet lever 11 is provided with a ratchet pawl 13 at one end of which is in contact with the row of teeth 6 of the belt 3 inserted through the base plate, and the other end thereof is connected to a pressing operation shaft 14.

A ratchet pawl 13 is provided between the fixed shaft 15 and the lever 11.
a spring 1 having an action in a direction in which it presses against the belt 3;
6.16 is established.

For tightening, one end of the lever 12 is a feed pawl 18 that engages with the tooth row 6, and a cutout 17 of the ratchet lever 11 is used to tighten the lever.
The other end of the lever 12 has a tightening shaft extending outwardly from the lever 12 and has no pull-up operation shaft 19.

Tightening is also done on the lever 12 and between it and the fixed shaft 15.
A spring 20 is provided which has the effect of lifting the feed claw 18 from the belt 3.

For tightening, the shaft hole 21 of the lever 12 has a long shape along the longitudinal direction of the lever 12.

The fastening device of the present invention having the above-mentioned structure is shown in FIG. 4 as a vertical side view in an assembled state.

The belt 3 is retained in a state in which the ratchet pawl 13 is engaged with the tooth row 6 of the belt 3 by the action of the spring 16, 16 acting on the ratchet lever 11, as shown in FIG.

When tightening the belt 3 further from this state,
To tighten, one end 19 of the lever 12 is pulled up against the force of the spring 20, and as shown in FIG. Since the belt 3 contacts and pushes the row 6, the belt 3 moves in the direction of tightening to the right in the figure.

As a result of this movement, the ratchet pawl 14 slides over the upper surface of the tooth row 6 next to the previous locking tooth row 6, overcoming it and falling into the locking position of that tooth row 6, thereby performing a ratchet feeding operation.

This tightening is performed while the lever 12 is being rotated, and the lifting end 19 is pulled up by applying force in the direction of pushing the lever 12 toward the feed pawl 18.
When the lever 12 is released after the ratchet feeding operation, the lever 12 is rotated in the state shown in FIG. It returns to the state, but at this time, lever 12
When the tip of the feed claw 18 touches the top of the tooth row 6,
Since the lever 12 can be moved relative to the shaft 10 by the length of the shaft hole 21, the lever 12 is pushed up by this contact and returns to its original position.

By repeating this tightening operation, the belt 3 is gradually tightened and can be maintained in an appropriate state.

When the belt 3 is released from the tightened state, by pressing the pressing operation end 14 of the ratchet lever 11 against the action of the spring 16, the ratchet pawl 13 at the other end is pressed against the tooth row 6.
Since the belt 3 is separated from the locking area, the belt 3 can be freely removed.

Incidentally, it is also possible to configure the lock release operation of the ratchet lever 11 to be performed in conjunction with the tightening operation within a certain rotation range of the lever 12.

As shown above, the tightening device of the present invention tightens and holds the belt while sequentially ratcheting the belt by the action of two levers on the belt, so it can be used without the need for preliminary adjustment before use. Appropriate tightening can be performed depending on the situation at the time, and the operation is simple, making it extremely useful for practical use as a tightening device.
