Description

Sandwich-type footwear strengthening part with firm or extremely not a half stiffness energy
The present invention relates to a kind of that propose by the main claim foreword, have an article of footwear firm or half firm performance.
As everyone knows, to some footwear, particularly athletic footwear styles, its sole assembly must be firm or to not a half stiffness energy.For example, to climbing boot or boots, footwear and roller skates (to two kinds on plain edition and a row formula wheel) by bike, or all be this situation with footwear to some track and field sports specialty.It is in order to obtain foot support preferably that this sole assembly is proposed this requirement, and/or user or sportsman can be sent to the power of maximum possible on the vehicle (as bicycle) of ground or his motion, thereby obtains the achievement that improves.
For the sole assembly that obtains different firm degree (is leather or rubber traditionally, or the mixture of rubber and/or synthetic polymer), usually adopt two kinds of diverse ways, be a kind of be in vamp, to fill in a shoe-pad, it is by making than being used for the firmer material of sole assembly, as timber, leather, cellulose conglomerate (commercial Tyke by name pine), or make, or make by bonding jumper or shaft-like insert by synthetic polyurethane resin, polypropylene, nylon etc.; Or adopt rigid material to make sole assembly itself, such as leather, timber or aforesaid synthetic resin.First method (shoe-pad) for example is used for climbing boot or boots, and second method then is used for carrying out as wood.
These solutions only part meet the requirements of purpose, that is, they only obtain the limited sole or the stiffness of shoe-pad.
A kind of footwear have appearred on market recently, its sole assembly or shoe-pad (particularly whole or part sole assembly) are made by composite, and these composites are combined by the fabric or the fiber (as the fiber of carbon, aromatic polyamides, glass or synthetic resin etc.) of the light material of the high elastic modulus in the resin that has been embedded in the bond effect.These solutions and manufacture method cause parts (sole or shoe-pad) to have sizable stiffness/weight ratio, make them be better than aforementioned two kinds of parts that method obtains greatly.But, the cost of these parts will be higher than the component costs that obtains with other described known method.This is for the expensive of some fiber (as carbon fiber) and because production process expensive, because compare with the production of the parts of only making by synthetic resin or by other aforementioned known method, this production process is slower usually, and more accurate.
One object of the present invention be exactly propose a kind of in footwear, be used as sole assembly or part sole assembly or shoe-pad, have article of footwear firm or half firm performance, though it can make footwear have the stiffness of requirement, manufacturing cost is very low.
For the expert of this technology, the article of footwear that is proposed by the main claim characteristic obviously can reach this and all the other purposes.

Described accompanying drawing represents such as the nailed climbing boots 2 or the parts 1 of the footwear of footwear 3 by bike, equips described parts and be the lower part 4 in order to strengthen described footwear, and described footwear comprise the vamp 7 that connects mutually with described part 4.Among the embodiment of footwear in being shown in Fig. 1 and 2, this lower part 4 comprises the sole assembly 8 of rubber or analog material, places thereon and has fixed one and played the firm of shoe-pad effect or half firm parts 1.The middle shoe-pad 9 of damping of an expansion polyurethanes or expansion ethyl acetic acid vinyl (EVA) can be set between parts 1 and sole assembly 8.On parts 1, placed a structure shoe-pad 10 removably usually.Thereby in these figure, parts 1 reinforcing section 4, and by the bonding or similar approach be fixed on the sole assembly.
On the contrary, parts 1 play real sole assembly in Fig. 3, and are connected with vamp with the common method such as bonding.Removably shoe-pad 10 is placed on the parts 1 as the footwear embodiment among Fig. 1 and 2, can set up rubber (or similar material) fragment 11 from the outside at the downside of described parts, and with as the known method of bonding be fixed so far on the parts.
Parts 1 are laminated deviceses, and it comprises that (seeing Fig. 6 A, 6B and 6C) three layers is overlapped together to form the thin layer of sandwich of one.Outer 13 and 14 are made greater than the material of internal layer 15 by stiffness, but the latter's thickness is greater than single layer 13 and 14, layer 13 and 14 (edge or sidewall 26 and 27 at parts 1 laterally link together so that layer 15 is enclosed within them) preferably are manufactured from the same material, especially by artificial synthetic plastic or synthetic resin, or by nylon, polyurethanes or polypropylene, or make by the composite of fabric that comprises synthetic resin and carbon, aromatic polyamides, glass or other synthetic resin and fiber.Layer 15 plays the core of the hierarchy thing 1A of parts 1, it is made by the material lighter than the composition material of layer 13 and 14, as the cellulosic material of artificial syntactic foam plastics or swollen resin (being shown in Fig. 6 C), natural product (as light wood, be shown in Fig. 6 A) or contain hole material (Fig. 6 B), this hole material that contains is made of the tangent cylindrical plastic element 17 of identical or different circular cross section or ellipse or polygonal cross section.Element 17 can be solid or hollow, and they define a honeycomb.
As mentioned above, each layer 13,14 and 15 links together and constitutes an integrative-structure thing 1A, and it can not be dispersed into its a plurality of components.Each component (multilayer) of works 1A ins all sorts of ways and is combined into one: as, if when adopting thermoplastic material, then to layer 13 and 14 through the in addition polymerization of the epoxy resin of pre-preg; If layer 13 and 14 has been adopted thermoplastic material, then the resin that limits core (Fig. 6 C) has been softened until fusion; Or adopting bonding that multilayer is combined, the method is by all being suitable for that thermoforming or thermoplastic material are made to layer 13 and 14.
The cost of the strengthening part 1 that obtains by the present invention will be lower than the similar parts that the known thickness made by composite equates, but its stiffness can be compared with them.Compare with similar known elements, the weight of parts 1 is very light, and its stiffness then can be compared with these layers at least.It is preferably all used (promptly along whole foot of the user) along the gamut of the lower part 4 of footwear 2 or 3, and can comprise somely having evenly or the part 20,21,22 of variable cross-section (Fig. 5 but still be the layering form), these parts can have different elasticity according to the position (for example having bigger elasticity at front foot) of their relative user's pin.This different elasticity also can obtain by the front end 23 towards parts 1 (with reference to wearing the user's of footwear 2 or 3 the pin sample) different-thickness decrescence that parts 1 is manufactured shown in Figure 4 and 5.The thickness of parts 1 also alternately is formed in forefoot portion or zone 20 is thicker, and then towards heel area 22 decrescence, perhaps thickness is uniform along its whole longitudinal axis A as illustrated in fig. 1.In addition, the cross section of parts 1 can be uniformly (Fig. 7 A), (Fig. 7 B) that change and to its transverse edge 26 and 27 decrescence or comprise rib 28 (Fig. 7 C) in order further to strengthen.
For making parts 1 have different stiffness, it replacedly comprises the different flanks (as the embodiment among Fig. 8 to 8C) that add.For example, forward part or front foot 20 can comprise a pair of parallel rib 33 down at least, do not have rib at foot arch part, and heel or ankle part 22 include only a center rib 34.
