Description
- The present invention relates to a shoe comprising an element for variably adjusting the shoe width.
- As is well-known, shoes are manufactured in different sizes, the sizes being adapted to the foot length of the wearers rather than to their width. This is obviously a problem since the foot width does not always conform to the foot length. In other words, in practice there is a need to adapt the shoe width for a specific foot length which determines the shoe size according to the wearer.
- To solve this problem, some shoe manufacturers have started to industrially manufacture shoes with different widths for each length or size of shoe. This method, however, is not necessarily practical since it greatly increases, on the one hand, the number of tools used in industrial shoe manufacturing and, on the other hand, the traders' stock due to the plurality of shoe sizes available on hand.
- Also, from EP 0 443 293 A1, shoes are known which can be adjusted both in width and in length with reference to the inner cup of the shoe. From DE 689 21 219 T2, adjustability in size, among others due to a curved plate in the sole structure is known. Furthermore, from DE 10 2007 031 225 A1, a shoe is known which is adjustable only in terms of the shoe sole, without any mention of involvement of the shoe shaft. Consequently, there is no sufficient adaptability of the entire shoe.
- Therefore, it is an object of the invention to eliminate the disadvantages of the state of the art, providing a shoe with an element that allows variable adjustment of the shoe width so as to minimize the stock of shoe sizes and the effort in shoe manufacturing and, at the same time, increase the wearing comfort of a shoe.
- The invention particularly aims at providing a shoe with an element for variable shoe width adjustment with which shoes can be manufactured industrially which provide a degree of comfort similar to that of a shoe manufactured by hand.
- The above-mentioned objects as well as other objects to be found in the description are achieved by a shoe according to
Claim 1. Other advantageous embodiments of the invention are indicated in the dependent claims. - According to the invention, a shoe having an element for variable shoe width adjustment is provided which allows the width adjustment of the exterior of a shoe so that the shoe can easily be adapted to the respective requirements and the comfort of the shoe wearer.
- The shoe according to the invention has a shoe shaft with at least one medial and/or at least one lateral opening and a shoe sole. The element for variable shoe width adjustment comprises for each one of the openings at least one support cap and a flexible element adjustable with the support cap, which is provided on the part of the support cap which faces the foot and can be fixed to the edge of the opening in the shoe shaft so as to close the opening, wherein the element has a higher flexibility than the shoe shaft. Furthermore it contains an anchoring element which can be rigidly integrated in the shoe sole and comprises at least one borehole channel extending in the direction of the support cap. It also comprises at least one adjusting means which connects the support cap to the anchoring element and is guided adaptably along the borehole channel, wherein the support cap can be adjusted, by means of the adjusting element, in relation to the anchoring element transversely to the shoe sole.
- In advantageous embodiments, the support cap of the shoe is embodied as a spherical segment or as a frame.
- Naturally, the adjustable support cap is to be employed preferably on the respective side and position of the foot, preferably in the anterior portion of the shoe at the widest part of the foot, medially (i.e. towards the inner part of the foot) or laterally (i.e. towards the outer part of the foot) or both as well as medially and laterally. The exact positioning of the support cap at the opening formed as an interruption of the shoe shaft will be explained below.
- In a preferred embodiment, the flexible element is formed as a padding element and connected with a sealing element at its side facing away from the shoe, so as to form a padding and sealing element.
- It is furthermore advantageous that the sealing element consists of a rubber- or silicone-like coating attached to the support cap and that the padding element consists of a neoprene material attached to the rubber- or silicone-like coating and being linked at the opening, wherein the rubber- or silicone-like coating is preferably formed as a soft rubber cap cover.
- Preferably, the flexible element can have a thickness which corresponds approximately to the thickness of the shoe shaft.
- In a preferred embodiment, the shoe is provided such that at the place of the opening, there is a recess in the lining of the shoe and instead of that the linked neoprene material of the flexible padding and sealing element is inserted.
- An advantageous embodiment of the shoe is structured such that the rubber- or silicone-like coating is glued to the neoprene material and/or the support cap is glued to the rubber- or silicone-like coating or attached by means of a plug-in connector.
- Other embodiments for integration of the element for variable width adjustment into the shoe are conceivable as well. For instance, an additional rubber wall can be glued or otherwise attached to the outside in order to protect the interior and the screw mechanism against dirt and dust.
- Preferably it is envisaged that the adjustment means is formed as a screw part and that the borehole channel of the anchoring element is embodied as a threaded hole with a thread matching the screw part.
- The screw part or the support cap, respectively, are preferably adjusted by means of a hexagon socket connector element with a matching heaxagon socket screw key via the exterior of the shoe sole. However, an exterior-hexagon socket screw connection or other types of screw connections are conceivable as well.
- According to a preferred embodiment, the adjusting means comprises two screw parts arranged on one side of the shoe sole at a single opening, wherein the anchoring element comprises two borehole channels and the support cap being divided into two parts corresponding to the two screw parts.
- In particular, the support cap of the shoe can be provided with an incision.
- It is an advantage if the element for variable shoe width adjustment is substantially arranged at a crease of the shoe and/or wherein the element for variable shoe width adjustment is substantially arranged at the heel of the shoe.
- In practice, the screw part has proven particularly suitable for rigid shoes, such as trekking shoes and the like. The screw part or the anchoring element, respectively, is preferably positioned both on the inner part and on the outer part of the foot, nearly precisely at the crease of the foot. Thus, the rolling movement of the foot could be slightly limited or the support cap slightly deformed during walking. This limitation or deformation, however, is unproblematic with rigid shoes (such as trekking shoes, for example) since normally stiff insoles are used in rigid shoes, basically preventing kinking. Thus, no or only a slight deformation is caused.
- In another embodiment, the shoe is formed such that the anchoring element is embodied as a grid and/or with a rough surface suitable for adhesive bonding or injection molding in the shoe sole.
- The lateral wings of the anchoring element can be formed as a grid structure or the like suitable for good and robust connection to the rubber mass of the shoe sole.
- Preferably, the anchoring element can additionally have lamellae or the like which are embodied for providing better anchoring in the shoe sole in the transverse direction.
- According to a preferred embodiment, the element additionally has a bushing which can be integrated in the shoe sole and is embodied for supporting the screw part or its second lateral part and/or the bottom part of the support cap, respectively, downwardly and laterally so as to provide more support to the support cap.
- The support cap preferably consists of plastic or a composite material, preferably with an interior metal grid.
- It is also advantageous that the support cap and/or the flexible padding and sealing element are individually adapted to the foot of the wearer and/or that the support cap is removably connected to the flexible padding and sealing element.
- The element for variable shoe width adjustment according to the invention offers particular advantages in case of shoes with a high shaft. Moreover, the element for variable shoe width adjustment according to the invention allows the manufacturing of a shoe providing greater wearing comfort to wearers with hallux or digitus.
- The shoe according to the invention is also suitable for counteracting pathological supination tendencies of the feet during walking. To achieve this effect, traditionally orthopedists modify shoes for instance by slightly thickening their soles either on the interior or on the exterior in height and possibly in width. For this purpose, suitable hard supporting materials, such as e.g. metal straps and the like, can also be integrated in the shoe soles which then additionally support the foot in the direction of the respective foot impairment. Such elements supporting a correct position of the foot, such as metal straps and hard or soft plastic elements, are either formed as integral parts of the shoe or as inlays.

FIG. 1 shows an embodiment of ashoe 1 substantially comprising a leather-like high shoe assembly orshoe shaft 3 with a frontlateral opening 4 in the shaft, asupport cap 5 which is visible through thelateral opening 4 and a shoe sole 2 with ananterior part 21 and aposterior part 22 of theshoe sole 2. Thesupport cap 5 of the element for variable shoe width adjustment can be variably adjusted in terms of lateral extending or retracting position by means of a screw part or adjusting means 7, covered by ascrew cap 6, and is thus adaptable to the requirements of a particular foot so as to maximize the wearing comfort of the shoe. -
FIG. 2 shows the inner structure of the element for variable shoe width adjustment, substantially comprising asupport cap 5 which laterally supports the foot and ananchoring element 8 integrated in theshoe sole 2, which maintains thesupport cap 5 in its respective lateral position by means of ascrew part 7 which can be screwed in or out further. -
FIG. 3 shows in a partial section of the shoe sole 2 theanchoring element 8 integrated therein, preferably injection-molded or glued in, which substantially comprises a central part with aborehole channel 82 and twolateral wings 83 withlamellae 84, which as a whole provide theanchoring element 8 with sufficient rigidity and anchoring surface within the shoe sole 2 so that thesupport cap 5 connected to it via thescrew part 7 is secured in its position. -
FIG. 4 indicates again the preferred position of theanchoring element 8 by means of dashed lines in the shoe sole 2 according toFIG. 3 , this time from above. In addition, arecess 23 is shown here. -
FIG. 5 a shows the main components of the element for variable shoe width adjustment, except for a flexible padding and sealing element described in the following, and their mechanical assembly, in a first rather extended state. - The element for variable shoe width adjustment substantially comprises: the anchoring
element 8 with theborehole channel 82 which is preferably formed as a threaded hole, thescrew part 7 having ascrew thread 74, a first 72 and a secondlateral part 73, and the support cap. Thelower part 51 of thesupport cap 5 is located in the recess 23 (according toFIG. 4 ), together with thescrew part 7 mounted rotatably therein, which can move back and forth depending on the degree to which thescrew part 7 is screwed into or out of theanchoring element 8. Thesupport cap 5 is held between the first 72 and the secondlateral part 73 and connected to thescrew part 7 via thelower part 51 such that thescrew part 7 can rotate in thelower part 51. By holding thesupport cap 5 with itslower part 51 between the first 72 and the secondlateral part 73 of thescrew part 7, wherein thesupport cap 5 simultaneously rotatably accommodates thescrew part 7, thesupport cap 5 is translatoric moveable back and forth by screwing in thescrew part 7 to a greater or lesser extent. - Thus, with a fixed integration of the
anchoring element 8 in theshoe sole 2, the position of asupport cap 5 mounted in this manner can be suitably adapted to a foot by means of a rotation of thescrew part 7; in other words, the foot is held more or less tightly in theshoe 1. -
FIG. 5 b also shows the main components of the element for variable shoe width adjustment shown inFIG. 5 a, in a second, retracted state. -
FIG. 6 shows the integration and embedding of thesupport cap 5 in theshoe 1. In an end-assembled state, theshoe 1 with the shoe assembly orshoe shaft 3, theshoe sole 2 and thelateral support cap 5 and ascrew cap 6 are shown. - The
support cap 5 is integrated in the following manner in theshoe 1 and in particular in the shoe assembly orshoe shaft 3 by at first linking a shoe lining 91 of the shaft in the interior of the shoe, at thelateral opening 4, to aneoprene material 92. Then, a rubber- or silicone-like coating is glued from the outside on theneoprene material 92 and on the seam for better distribution of forces, which coating is preferably formed as asoft rubber cap 93, the second side of therubber cap 93 being glued to thesupport cap 5. - It is also conceivable to apply the
support cap 5 with plug-in connectors, in which latter case thesupport cap 5 can be embodied individually and/or replaceably. Theneoprene material 92 and thesoft rubber cap 93 together form the flexible padding and sealing element mentioned above. - The
support cap 5 is preferably made of plastic or of acomposite material 1 with preferably an inner metal grid. Thesupport cap 5 can substantially have the shape of a spherical segment, as shown inFIG. 6 . - Alternatively, the
support cap 5, as shown inFIG. 7 a, can only be embodied as a frame, forming a cavity where e.g. the hallux can fit in. Advantageously, an additional, second support cap (not shown) can be provided with the embodiment inFIG. 7 a, substantially similar in shape to the support cap inFIG. 6 , which can be applied on the cavity defined by the rim of the support cap inFIG. 7 c. Thus, this latter embodiment accounts for the respective ganglion (on the outer side of the foot) or hallux (on the inner side of the foot). Preferably, the second support cap is fastened removably so as to allow for a plurality of design possibilities for the volume of the cavity. - As a further alternative, the
support cap 5 can be formed with anincision 5″, as shown inFIG. 7 c, so that a rolling movement (creasing of the shoe) is allowed to a certain extent and the cap is not detached even in case of adhesive bonding. - Also, other embodiments of the connection between the
support cap 5 and theanchoring element 8, which are achieved by means of thescrew part 7 inFIGS. 1 through 6 , are conceivable. For instance, two screw connection parts can be used, as shown inFIG. 7 b, wherein onefirst screw part 7′ can be arranged before the crease in foot direction and asecond screw part 7″ can be arranged behind the crease in the foot direction. The embodiment with theFIG. 7 b two screw parts can advantageously be used in shoes with flexible soles (e.g. shoes with a Strobel Stich), wherein therigid support cap 5′ is also divided into two parts corresponding to the two screw parts. An additional advantage of the embodiment inFIG. 7 b is the precise adjustability. - The support caps can be positioned, as shown in
FIGS. 1 through 7 c, at the crease of the foot or around the crease, wherein the support cap or support caps with the corresponding anchoring elements can be arranged, according to requirements, at the inner side or the outer side or both at the inner side and at the outer side of the foot. - Other alternative positions for the support caps are, as indicated in
FIG. 8 by thereference signs - The present invention can be used with a plurality of shoes, including sports shoes, running shoes, hiking shoes, orthopedic shoes, diabetic's shoes, boots and ski boots. Therefore, the term “shoe” used in this application comprises all types of shoes and boots which are mentioned above.
- The reference signs used in the claims are for better comprehensibility, but do not limit the claims to the embodiments presented in the figures.
