Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ski boot construction, and more particularly to a ski boot construction having a sole of constant length.

As is known, ski boots with soles of a constant length are already available on the market, regardless of the size of the boot.

This embodiment allows the binding of the boot to be placed at a predetermined distance, thus facilitating assembly of the binding to the ski.

In ski boots with soles of a certain length,
The ones shown in Swiss Patent No. 629942 and Japanese Patent Application No. 54-85847 have a sole of constant length as the size changes, the sole always being in relation to the sole of the boot. It is centrally positioned so that the front part or toe and the rear part or heel of the boot bulge out of the length of the sole by an approximately equal extent.

This embodiment, as described, has the advantage of allowing the use of bindings with ferrules and heel pieces at predetermined distances, regardless of size, but not specifically designed for said boot type. It has the disadvantage of requiring a binding type.

Another significant drawback is that when the skier secures the boot to the binding, it is practically impossible for the skier to see the binding ferrule along with the toe of the boot, so that the ferrule bulges in front of the boot. If the skier is placed under a section, the skier has no reference point and the attachment becomes difficult.

It is an object of the present invention to overcome such prior drawbacks by providing a ski boot construction with a sole of constant length that provides precise monitoring criteria so as to greatly facilitate the fixing operation during the attachment of the boot to the ski binding. The purpose is to eliminate the

Yet another object of the invention is to provide a ski boot with a constant length sole that can be attached to standard bindings, ie without the need for specially designed bindings.

Another object of the invention is to provide a ski boot construction that does not require special modifications or complex construction over conventionally manufactured boots.

A further object of the invention is to provide a ski boot construction which, due to its special configuration, provides sufficient guarantees of reliability and safety of use.

These and other objects, as will become clear below, are such that, according to the invention, the toe portion of the sole always bulges out at a constant distance from the toe portion of the boot shell for any size of boot shell. This is achieved by a ski boot structure characterized by the following:

Further features and advantages can be more clearly understood from the following detailed description of a ski boot construction with a sole of constant length, shown by way of example only in the accompanying drawings.

In the figure, the ski boot structure according to the invention consists of a sole 1 having a constant length regardless of the size of the boot.

For purposes of illustration and not to be construed as a limitation to the invention, it has been found that the sole should advantageously have a length of substantially approximately 270 mm.

A special aspect of the invention is that the toe of the sole
The purpose is that the part 1a retains the same relational position with the toe part 2a of the boot shell 2 in whatever size the boot may be of any type, ie a rear entrance boot or a front entrance boot.

According to the arrangement outlined above, the heel 3 of the shell bulges out to some extent in relation to the heel portion 1b of the sole, depending on the size of the boot.

With this arrangement, a nearly standard binding design can be used, with the ferrule 5 being exposed for viewing whenever the boot is fastened to the ski, while the heel piece 6 is placed under the heel 3. It consists of a generally flattened mold that fits within certain areas.

The present invention achieves that objective and, in particular, has a sole having its toe portion positioned in a uniform manner in relation to the toe portion of the boot and in substantially the same manner as conventional boots, a standard type of binding. It should be noted from the above that it should be pointed out that the provision of a sole boot of a certain length, while offering the possibility of using the binding ferrule 5, while ensuring that the binding ferrule 5 is always fully observed during the attachment of the boot to the binding, is to be noted. Can be done.

Furthermore, it should be pointed out that the steps for securing the boot to the binding remain largely unchanged from conventional boots and are therefore well received by users.

In embodiments of the invention, suitable dimensions, associated shapes or materials can be used to suit individual requirements, provided that the material does not predicate a particular application.

[Brief explanation of the drawing]

Claims (1)

[Scope of Claims] 1. In a ski boot structure in which a sole 1 of a constant length is attached regardless of the size of the boot shell 2, the toe portion 1a of the sole is attached to the boot regardless of the size of the boot shell 2. This ski boot structure is characterized in that the toe portion 2a of the shell always bulges out at regular intervals. 2. The heel 3 of the boot shell 2 is configured to bulge out from the heel portion 1b of the sole 1 by a length that depends on the size of the boot shell. Ski boot construction as described.
