Inner lining shoe for ski boots having a one piece tongue assembly

Abstract: In an inner lining shoe (10) for ski-boots an integral or one piece tongue assembly (12) consists of a tongue (14) connected to a fore part of upper (16),said fore part of upper (16) being joined to a rear portion of upper (20) by means like sewings (34,36) and to a sole (24) by joining its lower peripheral edge (38) to a peripheral edge (40) of said sole.

Description: The present invention relates to a process of manufacturing an inner lining shoe to be put on within a rigid boot, such as a ski-boot with fore entry, in which the standard tongue is integrally formed with part of the upper of the lining shoe. It is known that the lining shoes to be used together with ski-boots are provided at their leg portion with tongues having the purpose of shielding the leg from a direct contact with the rigid shell of the boot. From DE-U-8113635 there is known an inner lining shoe for ski boots having a tongue assembly which is integrally formed with the upper of the shoe, it being delimited by side slits in the upper. EP-A-0259720 discloses an inner lining shoe for ski-boots having a tongue assembly wherein the upper is fastened at the lower perimetral edge hereof to the sole of the shoe. Usually the tongues provided in the lining shoes to be inserted into a ski-boot are either fastened to the upper, for example by sewing, or secured in a floating manner, namely anchored to the upper by means permitting a sliding motion thereof in a longitudinal direction with respect to said upper in order to permit said tongue to be positioned in the most adequate manner with respect to the upper in order to fully fit the foot to the shoe and thus to the boot. Said means for anchoring the tongue to the upper consist of a sewing or a pin-like member slidable within a groove of the upper and may cause thickenings or greater encumbrances just at the level of the instep wherein said thickenings can create uncomfortable situation which are difficultly bearable especially in sportwear, such as the ski-boots, in which said situations are to be avoided as much as possible. In order to eliminate these drawbacks the process of claim 1 has been provided The features and advantages of the present invention shall more clearly appear from the following description of a preferred embodiment thereof, not to be construed in a limitating sense, with reference to the accompanying drawings, in which: Fig.1 is a perspective view of a wearable shoe comprising a tongue assembly made according to the process of the present invention; Fig.2 is a cross-section view of the same lining shoe particularly showing the tongue assembly Fig.3 is a perspective view of a tongue assembly shown in a condition removed from the remainder of the shoe; Fig.4 is a perspective view of the remaining part of the shoe adapted for the connection to the tongue assembly of fig.3. Referring to the above figures;the shoe 10 comprises an integrally formed tongue assembly consisting of the proper tongue 14 joined to a fore portion 16 of the upper by suitable means such as for example the sewing 18 (better viewable in fig.3).The upper is also formed by a remaining rear portion 20 including a leg part 22 and is connected to a sole 24 by per se known means, such as cementing or thermowelding of parts containing adhesive means, by melting and solidifying again. Said integrally formed tongue assembly 12 is provided in the fore part 16 of the upper with side edges, the edge 26 of which can be seen, which are joined to corresponding fore edges 28 and 32 of the rear part 20 of the upper by means of sewings such as the sewing 34 shown in fig.1 and the sewing 36 shown in fig.2.The aforesaid fore portion 16 of the upper is also provided with a lower peripheral edge 38 which can be coupled with a peripheral edge 40 of said sole 24 and can be joined thereto by known means, such as cementing or thermowelding. Owing to obvious manufacturing reasons the fore portion 16 of the upper is provided with sewings 42 and 44 permitting it to be given the desired shape and function. For sake of description completness an elastic ribbon 46 is shown having the purpose of causing tile shoe and particularly the upper thereof to adhere to the internally fitted foot. A particular advantage of a shoe manufactured with the process according to the present invention is the reduction of the number of spare parts to be stored, since for the series manufacturing of these shoes it is sufficient to have available one type of tongue assembly for each shoe size and one type of shoe remaining part every two shoe sizes whereby the number of types of shoe remaining parts to be stored is reduced to one half. If consideration is paid to the fact that said shoe remaining parts are the greater part of the shoe the storage economy which can be attained is evident. The above description relates to a specific embodiment of the present invention which is not to be interpreted in a limiting sense and it will be evident that substituting equivalent parts shall be conceivable for those skilled in this field upon reading the above description. For example the sewings 34 and 36 might be substituted for by cementing or thermowelding joints and the connection between the peripheral edges 38 and 40 might be effected by sewing, as it is used in the shoe manufacturing technology.

Claims: A process for manufacturing an inner lining shoe for ski boots, which comprises the following steps: providing a tongue assembly (12) consisting of a proper tongue (14) integrally formed with a part (16) of the upper so as to have an inner padding which extends continuously along said tongue and said part, avoiding inside thickenings at the instep level, wherein the part (16) of the upper is an extension of the tongue (14) and consists of a fore part adapted to constitute the whole soleless toe portion of the upper of the shoe; providing an upper remaining part (20) including a leg part (22), connected to a sole (24); connecting said extention of the tongue assembly (12) to the upper remaining part (20) and to the sole (24) through fastening means (34, 36) in position remote from the instep. A process according to claim 1, wherein the part (16) of the upper integrally formed with the tongue (14) comprises a lower peripheral edge (38) which can be anchored and secured to the sole (24), and two rear sides (26) which can be connected to the upper remaining part (20). A process according to any of claims 1 and 2, wherein the fastening means (34, 36) consists of sewing, cementing or thermowelding means.
