Description of drawings

From the accompanying drawing that provides below by the limiting examples mode, the present invention will be more apparent, in the accompanying drawing:

Fig. 1 is the decomposition diagram according to first embodiment of footwear of the present invention;

Nine kinds of sole variants when Fig. 2 A-2I demonstration is seen from above;

Another sole variant when Fig. 3 A-3B demonstration is seen from above is in not distortion and deformation position respectively; With

The schematic cross sectional views that Fig. 4 A-4M passes ten kinds of variants of deformable sole element for Fig. 1 line 4-4.

The specific embodiment

With reference to figure 1, footwear of the present invention comprise: the upper member of general type or vamp 1 in this area, and it for example is fixed to sole 2 by stitching or bonding mode by common mode; And the interior end 3 of footwear that will be inserted in the inboard sole of vamp 2 tops.Vamp can be made by the elastomeric material at least in part of common type in any material that is suitable for application target, particularly footwear industry.

Advantageously, near will being fixed to the following perimembranous of sole, vamp can comprise the liner 1B that is made of elastomeric material at least in part, so that the size of vamp, particularly its width can stand distortion.

Sole 2 shown in this example is combinations of two parts linking together, and these two parts are: intermediate member 4 contacts its lower surface 4A and above ground portion; And external component 5, this external component comprises a plurality of elements of kiss the earth and is used as heel 5A and shoe tack 5B.Should note, external component is very conventional to those skilled in the art, and also can be by the parts of different numbers, for example heel parts and single preceding foot part form, and this external component is used as damping and is made pin support the element of usefulness on the ground best.

With reference to figure 1, the intermediate member 4 of sole 2 comprises a plurality of parts, i.e. deformable part 6A, 6B and a non-deformable basically 7A, 7B, 7C; Described deformable part 6A, 6B can make the sole size change at least in part, and make the sole size adapt to the size of wearer's s plantar region.

It should be noted that among the present invention that the definition of deformable and non-deformable material should be understood like this: if a kind of material does not experience variation in the identical power that makes the deformable material distortion of being attended the meeting, then this material is defined as non-deformable material.

According to preferred embodiment, non-deformable 7A-7C of intermediate sole 4 made by leather, and deformable part 6A-6B is by the plastic deformable material that is suitable for application target, elastomer for example, and particularly natural or synthetic or vulcanized rubber or injection molded thermoplastics material are made.

Preferably, deformable part 6A-6B (Fig. 4 A-4M) has the flange 8 of two coplanes that link together by middle corrugated part 9, and described middle corrugated part 9 can have different geometries, shown in Fig. 4 A-4M.In some embodiment (4A-4G), the flange 8 of deformable part is contained in the seat portion 10 of depression, the seat portion 10 of this depression is located among non-deformable the 7A-7C, and its shape is identical with described flange with size, makes the upper surface 4B coplane basically of flange 8 and sole intermediate member 4.Deformable part 6A-6B and non-deformable 7A-7C are preferably by being molded in deformable part on non-deformable, and perhaps by gummed or stitching, perhaps other modes of using always by those of ordinary skills are rigidly connected to together.

In other embodiment (Fig. 4 H-4M), flange 8A contacts lower member 5 with whole deformable part 9 with the ground of sole and becomes one.In this latter event, shoe sole component 5 and deformable part are for example made by common molded or injection molding by same material or different materials; But the density of the material of parts 5 is greater than the density of the material of parts 4.Alternatively, flange 8A can for example be fixed on the leather sole 4 by gummed, stitching, common mode or injection molding in the usual way, and these leather sole 4 bottoms can comprise the seat portion (not shown) identical with above-mentioned seat portion 10.Alternatively, flange also can be located at parts 5B below, and is fixed on the leather sole 4 with described parts 5B.

Shown in Fig. 4 A-4M, corrugated part 9 can have difformity, for example it can have U or the V-arrangement shape that faces upward or downward, as Fig. 4 A, 4B, shown in the 4M, or have two V-arrangements (Fig. 4 C) that mutually tilt, or it is big and towards a plurality of U-shapeds that replace (Fig. 4 D) in the center of corrugated part size, or towards a series of length that replace, narrow identical U-shaped (Fig. 4 E), or have a U-shaped (Fig. 4 L) that take all of end and branch assemble when being in deformation position not, or with in a series of wide U-shaped (Fig. 4 F) that replaces of narrow-minded U-shaped, or the center than the inclination V-arrangement (Fig. 4 G) of a series of different sizes of side director and in deformation position not T-shaped and parts (Fig. 4 H that take the shape of the letter U in deformation position, 4I).In order to hold the deformable part of given shape better, the wall energy that is located at the seat portion 10 that is used to hold described deformable part 9 in the sole 4 comprises the inclined wall of upwards assembling 10A (Fig. 4 C) or assembling 10B (Fig. 4 D) downwards, to play the effect of the support portion of the respective wall that is used for corrugated part under deformation condition not.Advantageously, these abutment surfaces do not link together, thereby help the corrugated part distortion.Under the situation of the inclined wall 10B that assembles downwards, these abutment surfaces make it possible to hold the corrugated part of large-size, limit the corrugated part surface simultaneously and contact with ground.

Corrugated deformable part is more preferred than flat deformable parts, and described flat deformable parts promptly has for example those flat deformable parts of rectangle of continuous closed cross-section; In this, adopt corrugated part, if described deformable component is broadened to be applied to when required power is flat less than it the power on the described deformable part.When it is subjected to making the tractive force of its distortion, this deformable part fracture or with non-deformable part from risk littler.

Also advantageously, deformable part has continuous elongate shape, and with respect to sole longitudinal axis S symmetry location, reason is that this layout and shape are guaranteed resistance and the distortion of more uniform sole that deformable part is bigger.This has also limited the quantity that deformable bellows terminal parts 13 is opened wide in the edge of sole in the shoes.

Except different transverse shapes, deformable part can also have different longitudinal lengths or shape and position.

Fig. 1 has shown the first deformable part 6A with U-shaped shape, and the outward flange of itself and sole as one man extends that part of from sole arch (planter arch) to the forward foot in a step of sole, and the distal portion of U-shaped is in the below that sole encircles; Fig. 1 has also shown the second deformable part 6B that overarches slightly, and it crosses sole longitudinal axis S extension in arch place under foot.First 6A allows peripheral distortion, and promptly the front portion of sole broadens, and second deformable part allows sole elongated.

Fig. 2 A has shown to have the first deformable part 16A that equals the close-shaped of sole periphery substantially and be positioned at the sole outer edge.The described close-shaped any part of sole that can make broadens.In order to improve this broadening, second first closure 16A that can add Fig. 2 A to, this second one is identical with first one but be located at its inside, represents with 16B in Fig. 2 A.

Fig. 2 B has shown a pair of deformable part 26A that waveform is extended, they are located in the forward foot in a step symmetrically about the sole longitudinal axis, and end 26C terminates in the sole arch place of toe place and sole, and Fig. 2 B has also shown second 26B, it crosses described axis waviness, and is located at sole arch place.

Fig. 2 C has shown the first deformable part 36A, and it overlaps sole longitudinal axis S substantially and upward extends to heel areas from loe zone; Fig. 2 C has also shown second 36B, and it crosses described axis and is located at sole arch place.

Fig. 2 D has shown the deformable part 46A of the M shape of a pair of flattening, it extends symmetrically about sole longitudinal axis S in preceding foot, and end 46C terminates in the sole arch place of toe place and sole, Fig. 2 D has also shown the second lengthwise V-shape portion 46B, and the summit of V-arrangement is positioned at the heel place, and its end terminates in sole arch place.

Fig. 2 E has only shown a deformable part 56A, and it is with identical with reference to figure 1 described part 6A.

Fig. 2 F has shown deformable part 66A, it overlaps that longitudinal axis S goes up and extends to sole arch district from the heel areas of sole, here it is divided into two 66B of arch branch, and these two arch branches are with respect to longitudinal axis S symmetry, follows sole profile and extends and join once more at the sole toe place.

Fig. 2 G has shown first identical with the part 16A of Fig. 2 A substantially 76A and has equaled the part 6B of Fig. 1 substantially but the central part 76B that links to each other with part 76A.

Fig. 2 H has shown a plurality of

deformable part

86A and 86B, and it utilizes parallel and forms latticed perpendicular to a plurality of parts of sole longitudinal axis.

Fig. 3 A, 3B have shown the 96A of arcuate deformable portion, and it is located in the preceding foot of sole symmetrically with respect to sole longitudinal axis S, and terminal part 13 is positioned at the toe place of sole arch place and sole.

In order to make the footwear distortion, power F (Fig. 3 B) must be applied on the sole along the direction perpendicular to the footwear periphery substantially, so that sole broadens and/or is elongated or shorten, i.e. and the thickness of deformable part, for example shown in Fig. 3 A and 3B, can be transformed into F2 (Fig. 3 B) from F1 (Fig. 3 A).According to the present invention, no matter described distortion is the distortion on width or the length, between 1 to 10mm.

For sole of the present invention being maintained in the deformation state of wanting, the end 3, comprise one or more size appropriate rigidity liners 14 in the footwear.Preferably, these liners comprise the par 14A that is used to cover sole, and two side portion 14B extend to sidepiece along vamp from par 14A.Preferably, par 14A is the grille-like that has hole 14C, and liner 14 is by the non-deformable material of rigidity, and for example metal or the plastics that have a similar rigidity characteristics are made.Liner preferably is fixed to the lower surface at the end 3 in the footwear rigidly, for example it be glued on it or by injection molding or common mode method the end in footwear make.

Utilize liner shown in Figure 1, in case the end in the footwear 3 is inserted in the footwear, just can obtain two kinds of different-effects: the forefoot part of sole 4 is to the width L1 that equals gasket width L2, and sole is kept this deformation state by this rigid liner 14.

According to that part that sole will be out of shape, can use the liner of greater or lesser size and suitable shape.For example, utilize the cross insert 24 shown in Fig. 2 C dotted line, sole can be out of shape on length and width in forefoot region, and keeps described distortion.If remove debranching enzyme 24A and only stay the 24B of branch, the distortion on the length then can only be arranged.Also only allow the distortion on the width in heel areas shown in Fig. 2 D dotted line with 34 liners of representing.

In order to prevent in the footwear end 3 owing to rigid liner 14 keeps rising from sole, liner 14 can comprise the device 18 that liner 14 is detachably fixed to sole.For this reason, liner 14 for example can comprise from the outstanding external screw thread tooth portion 19 of its lower surface, with pass the hole 20 that is located in the sole 4 and with the element 5B (representing) that is located at the outer sole parts with arrow A in screwed hole 5C engagement.

According to the present invention, for each footwear sizes of footwear of the present invention, the buyer can obtain the end in a plurality of different footwear, and the end has different rigid liners in each footwear.For example,, then can attempt the end in a plurality of footwear, utilize adaptive wide, the normal or narrow plantar foot area in the end in the different rigidity footwear that No. 8 footwear use with respect to No. 8 footwear if the buyer wears footwear No. 8.Chosen in the footwear of the most suitable buyer's pin at the end, the end in the described footwear is inserted in the footwear, then by the rigid liner that is fixed to the end in the footwear, sole just can be out of shape, and makes it adapt to size of the interior end of footwear and keep described distortion between the operating period of footwear.

Therefore, by the present invention, for identical footwear sizes, the buyer can make all of sole or only some part adapt to the approximately degree of positive and negative half footwear sizes.

It should be noted that the flange 14B (Fig. 1) by means of rigid liner 14, the shape and size of vamp 1 can be revised at least in part, and particularly its shape and size of making parts or liner 1B by elastomeric material at least in part can be revised at least in part.In this, in case insert at the end 3 in the footwear, realized not only that by described flange 14B the sole that adapts to the individual broadens, and has realized that also vamp broadens.

At last, should note, the present invention only passes through case description, and various variants can drop in the identical principle of the present invention, and for example sole 2 can be by replacing substantially non deformable leather component 7A-7C and making element 5A-5B and deformable part 6A-6B for example becomes one by common molded and/or injection molding and described parts 7A-7C and makes with a slice plastics fully with plastic components.
