DE1955615C3 - Footwear, in particular ski boots, with linings - Google Patents

Description

The Hauptpaicnt 16 85 776 relates to footwear, in particular Ski boots, with a lining made of foamed, open-cell material in the form of a the sole carrying the foot and from the sole plane extending out from the top of the sole, the foot at least partially enclosing rope walls, the outer contours of the lining of the boot cavity are precisely adapted and their material is made of stiff, only slightly elastically deformable foam exists, which yields up to 30% of its layer thickness when loaded by the boot wearer.

The additional patent represents a further development of the HMüpt patent, with the underlying task the relatively firm inner lining to better adapt to the shape of the foot of the boot wearer to this Way z. B. minor abnormalities of the foot .niszugleichen.

The solution to this problem is that the Wall of the lining has zones of different elasticity.

It is particularly beneficial. who; n the lining S is multilayered, on which the foot facing side a layer of a material is arranged, which is softer than the material of the rest Lining is.

The lining is elastically deformable to a small extent in order to fix the foot firmly in the shoe; she is. in deviation from the subject of the main paient. no more than 4U ¹ Vo elastically deformable. It is Voneil if, as is known, lasers are added to the foam material of the lining, whereby the lining

is an increased compressive and tensile strength as well as a better dimensional stability.

The invention is described below with reference to a drawing. The figure shows a section through the Schnhinnenlininer 2 transversely to the boot longitudinal axis in the area of the foot crook in a schematic representation. The inner lining of the Footwear according to the invention consists of the wall 1 with the zones 10, 11 of different stiffness, in only a small amount of elastically deformable foam and know on the inside facing your foot a weuhelastic layer 9, which the foot in the relatively steep inner lining is soft. The zone 10 is made of more elastic foam than the zone ti manufactured. This more elastic zone 10 is preferably present in the shoe inner lining where foot anomalies, Knuckles or nerves cannot tolerate pressure.

Fibers 12, in particular Made of polyamide, embedded in the foam of the liner to provide compressive and tensile strength and thus increase the dimensional stability of the lining / u.

The technical effect of the inventive idea consists in the wall of the lining with zones under different elasticity, with a soft zone running parallel to the wall of the lining for the foot may be facing, which absorbs minor anomalies of the foot by elastic deformation, while a soft elastic zone transverse to the relatively hard wall of the liner, major anomalies, z. B. picks up pressure-sensitive ankles, which are localized differently from foot to foot, without special Adjustment work is necessary and without the responsibility for the firm fit of the foot in the shoe, relatively hard lining must be made softer overall.

Class A 43 B Gr. 5-04 Issued on: 16 JUU 1381

The patent 19 55 6Ί5 is partially declared null and void by judgment of the Federal Court of Justice of November 18, 1980.

Claim 1 of patent 19 55 615 reads:

"Lining for a ski boot according to features 1. to (a) of the main patent 16 85 776,

4. (b) where the foam is exposed to stress from the boot

carrier yields up to 40% of its layer thickness.

5. Your wall (2) has zones (9. 10, 11) of different elasticity. "

Claim 2 of patent 19 55 615 reads:

"Lining for a ski boot according to claim 1, the zones thereof (9, 10, 11) of different elasticity extend parallel (9) or transversely (10) to the wall (2) of the lining. "

Claim 3 of patent 19 55 615 reads:

"Liner for a ski boot according to claim 1, the wall of which (2) is formed in multiple layers, with a layer (9) made of a material being arranged on the side facing the foot which is softer than the material of the rest of the lining. "

Claim 4 of patent 19 55 615 reads:

"Lining for a ski boot according to claims 1 to 3, fibers (12) are molded into the wanaematerial (2). "

Claims (4)

Patent claims: 1. Footwear, especially ski boots, with a Lining made of foamed, open-cell material in the form of a sole that supports the foot and of extending upwards from the sole plane, at least partially enclosing the foot Sidewalls, the outer contours of the lining of the Siiefelhöhlung matched exactly and their material consists of stiff, only slightly elastically deformable foam, which yields up to 30% of its layer thickness when loaded by the boot wearer, according to I lauptpalent ! 6 85 776, characterized in that that the wall (2) of the lining Zonon (9. 10. II) has different elasticity. 2. Footwear according to claim 1, characterized in that the zones of different elasticity extend parallel (9) or transversely (10) to the wall (2) of the lining. 3.
