Description

The footwear of waterproof and breathable
Technical field
It the utility model is related to a kind of footwear of waterproof and breathable, the footwear has upper of a shoe arrangement, bottom in installation (Montagebrandsohle) and sole, wherein, the upper of a shoe arrangement has cladding material and inner layer material, the inner layer material Functional layer with waterproof, can pass through vapor, the inner layer material are laminated with the cladding material, the inner layer material end of bottom Go out from the cladding material end of bottom towards end stretch in the installation and be connected by seam with bottom in the installation, and the seam Sealed.
Background technology
The footwear of waterproof and breathable has breathable and the thus cladding material of porous, such as by leather or textile material It is made.With a kind of inner layer material realize with water vapo(u)r transmission simultaneously water proofing property, the inner layer material have waterproof, can Through the functional layer of vapor, the functional layer can be provided with the side towards the cladding material yarn fabric back side and It can be connected on side away from the cladding material with pad.The upper of a shoe end of bottom can be with bottom suture or bonding in installation. Outer bottom (Laufsohle) is arranged to the upper of a shoe end of the interior bottom and the bottom being connected with the interior bottom, and the outer bottom is for example by moulding Material or leather are made.The sole can be glued or injection-molded.The connecting sewing between bottom and upper of a shoe end must be close inside Envelope, to ensure water proofing property.
Be initially these of cladding material and inner layer material lower end are sutured to each other by means of unique seam and Sutured with the interior bottom.This based on viewpoint be that the seam is likely located in the region surrounded by the outer bottom waterproof and can It can thus protect the outer bottom from the water from outside intrusion.However, it has been proved that when water reaches the cladding material, such Determined that in footwear after the of short duration time wetly inside the footwear.It is verified as its reason, the outer layer for such footwear Material (can be leather or textile material) is not only extended laterally on direction at it but also booted up in its Longitudinal extending side Water.Thus, in the cladding material and this can be transferred to from the cladding material from the outside water for reaching the cladding material Intrusion is until the lower end of the upper of a shoe in the outer bottom after in the functional layer of the yarn fabric back side or the inner layer material, from this Lower end can reach the inner side of the footwear by means of two kinds of guiding mechanisms.On the one hand, in the cladding material and in the weaving The thing back side or the downward seam invaded until the cladding material, the inner layer material are connected to each other with the interior bottom in the functional layer The water at place, via by the seam in the functional layer caused by these perforations and through wick-like water guide suture Reach the inner side of the footwear.On the other hand, often occur when producing the inner layer material:In the trimming of the inner layer material of the bottom The small braided wire of place, the yarn fabric back side and/or the pad stretches out and is used as from the outer layer material around the trimming of the functional layer Expect to the water bridge of the pad to work.
The remedial measure for mentioned water bridge mechanism is illustrated in DE 38 21 602.Here, the cladding material The lower end of the inner layer material is not extended downward into, but the lower end of the cladding material passes through in the outer bottom inner loop Around connect band form, the upper end of the connect band and the cladding material suture and the lower end of the connect band passes through set Last carving stitches (Strobelnaht) and the bottom inner layer material and also sutured with the interior bottom.The connect band by not water guide material It is made, such as the guipure by being formed with monofilament material is made.The cladding material with the guipure is reached in the cladding material The water of connecting sewing, it is impossible to the connecting sewing further marched between guipure, inner layer material and interior bottom.Additionally, the guipure The sole it is injection-molded during passed through by the plastics of liquid, the plastics reach being located at for the yarn fabric back side in this way The region at the guipure rear reaches the functional layer.Thus, bond the textile material at the back side or the functional layer and forbid this The transmissibility of functional layer or the region inside the injection-molded outer bottom for sealing the functional layer.
These measures are certified as forbidding the water bridge between the cladding material of the footwear and inner side largely effective.But What is desired is that using the guipure with least 10mm width, thus ensure to use around during the injection-molded process In the 5mm of the liquid plastic of outer bottom minimal flow opening.Remaining 5mm for for by an end of the guipure with should Cladding material sutures and another end is with being required for the inner layer material and the seam protuberance of the interior bottom suture.Cause It must be covered for the seam connection in product shoes between the guipure and the cladding material by injection-molded sole, should Technology requires that the minimum insertion depth of the upper of a shoe is 14mm in the injection-molded outer bottom.This causes the correspondence at the outer bottom edge Minimum altitude.However, due to fashion reasons, also require that footwear has substantially thinner injection-molded sole now.
Guipure for the footwear of the above-mentioned type is generally made up of the material of relative rigid.Therefore it is difficult to, in no shape In the case of increased fold (especially in the region of the toe cap), and thus the footwear matching degree without deterioration feelings Under condition, by guipure modeling to the region at the interior bottom.
