Description

Pivoting shoe with seal
The present invention relates to a shoe with a pivoting sole comprising a front part and a back part placed on a sole, wherein the sole incorporates a hinge pivotally connecting the front part and the back part for opening the shoe and wherein the shoe is maintained in open position without external force.
Such shoe is for instance known from EP 2 173 208, Dutch patent 1020208 and Dutch patent application 2006983. The shoe may be opened and closed by turning the front part of the shoe relative to the back part of the shoe. By opening the shoe, the entrance of the shoe is enlarged, facilitating stepping in and out the shoe. Such shoe may observe sealing problems at the interface of the front and the back part of the shoe. Dirt or water may enter the shoe through the interface. Moreover, when closing the shoe, part of the foot, socks or fingers may get trapped at the interface.
Also WO 2005/070246 describes a shoe comprising a front part and a back part placed on a sole. However, in contrast to the shoe of the invention, the sole is not provided with a hinge. The sole is flexible. By flexing the sole, the front part and the back part are moved tangential away from each other, opening the shoe. Between the adjacent rims of the front part and the back part of the shoe an flexible insert body is provided to create an expanding stopper. The stopper prevents excessive bending of the sole and stops dirt getting inside the shoe. The shoe according to WO 2005/070246 is not stable in open position; on the contrary, the bending stresses in the sole tend to straighten the sole again if the bending force is released. Moreover, similar, the expanding stopper will tend to straighten the sole. When stepping in or out the shoe, considerable force has to be exerted on the shoe to open it and maintain it in open position. Therefore it is necessary to use both hands. This is impractical and undesirable. In particular this applies for young children, older people and disabled persons. Besides that, a little awkwardness may have major consequences. When the opening force is accidentally released the shoe will be moved with considerable force, under the straightening force of the sole and of the flexible insert, to its closed position. Fingers and feet may then be easily trapped between the front and the back part of the shoe.
The present invention intends to solve one or more of the problems of the prior art as described above, and it is in particular an objective of the invention to provide a pivotable shoe that is tight and safe.
The shoe according to the invention is characterized by one or several of the appended claims.
In a first aspect of the invention the shoe is provided with one or more seals for at least a part of the interface of the front part and the back part of the shoe and the one or more seals being adaptable to the specific position of the shoe without exerting a substantial closing force. The seal will prevent water and/or dirt to penetrate the shoe at the spot of the interface between the front part and the back part of the shoe. When the shoe is opened to facilitate stepping in and out the shoe, a broad opening will arise between the front part and the back part of the shoe. The seals will keep this opening at least partly sealed, even in open position of the shoe. The shoe is stable in the open position, even without exerting an external force. The seals are configured such that they exert no substantial closing force on the open shoe. This will prevent unintended closing of the shoe. Accordingly trapping of parts of the foot, fingers or socks is prevented.
According to a further aspect of the invention the seal covers the interface. Such seal may be reversible extendable. The seal will be extended by opening the shoe and will keep the opening between front and back part of the shoe covered. As the seal is reversible it will return to its original shape when closing the shoe. The seal may be extendable over a longer distance at a position further away than closer to the hinge. Such seal will optimally adjust itself to the shape of the opening that will arise between the front and the back part of the shoe, when opening the shoe. The seal may have a converging shape, with the broader part located at distance from the hinge. A seal with a certain stretch index per unit of length will allow more elongation over its broader part. By placing that broader part of the seal at the place where the opening between the front part and the back part of the opened shoe will be largest, the seal will optimally accommodate to the opening that has to be sealed. According to the invention the broader part of the seal has preferably a width in the range of 65 to 95 mm. The narrow part of the seal near the hinge has typically a preferred width in the range of 5 to 20 mm. The angle between the converging sides of the seal may be more or less similar to the opening angle of the shoe. This will result in an even stress distribution in the seal, which will be stretched uniformly. According to the invention such seal may made of a fabric and for instance comprise polyurethane .
To a further aspect of the invention a seal is provided between the adjacent edges of the interface. Such seal is preferably resilient compressible and may consist of two complementary parts, a first part at the edge of the front part of the shoe and a second part at the edge of the back part of the shoe. Such seal between the adjacent edges of the interface will seal the interface optimally and may be produced out of easy to clean materials.
According to a further embodiment of the invention one or more of the seals run from the medial side to the lateral side of the shoe. In this way both interfaces of the shoe, at the medial and the lateral side, are sealed by the same seal. Such seal may be positioned between the sole and the outer sole of the shoe. The seal may also seal the sole in particular where the hinge is positioned.
According to another aspect of the invention the top of the seal is located in a range of 20 to 40 mm distance from the hinge. This will provide a balance between the pivoting and the sealing properties of the shoe.
In a further embodiment of the invention the seal comprises extensions of the front part of the shoe and/or of the back part of the shoe. These extensions cover the opening between front part and the back part of the shoe. One or more of the extension (s) and/or one or more of the shoe parts may at an interacting surface be provided with resilient compressible material. Such resilient compressible material will enhance the sealing characteristics of the extensions and also the wearing comfort. The seal may further comprise a seal-element between at least one extension and the other shoe part or the extension thereof. In this way the seal with the extensions is provided with an additional barrier against water and dirt. Such seal- element may be a stretchable or flexible folding seam. This will enhance the relative movement between the front and back part of the shoe or the extensions thereof and still maintain the sealing characteristics. Moreover a suitable folding seam will not be perceived and accordingly will provide sufficient wearing comfort.
According to again another aspect of the invention the front part and/or the back part of the shoe are provided with stiffening means near their interacting area. Such stiffening means will support a close matching of the front and the back part of the shoe in the area of the sealing interaction.
The various aspects of the invention will now be described in more detail and will be elucidated, by way of example only, with reference to the accompanying drawing which shows in Figure 1, a schematic view of a shoe with a
pivoting sole in closed position;
Figure 2, a schematic view of the shoe of figure 1 in open position;
- Figure 3, a schematic view of an embodiment of the shoe according to the invention in closed position; Figure 4, the shoe of figure 3 in open position; Figure 5, a schematic view of the shoe of the figure 3 and 4, provided with an additional seal; - Figure 6, a pivoting shoe without laces, providing with sealing extensions at the front part and stiffening means at the back part, in closed position; and
Figure 7, the pivoting shoe of figure 6 in a stable open position.
In figure 1 a shoe 1 with a pivoting sole 2 is shown. The sole consist of a front part 3 and a back part 4. The front part 3 and the back part 4 of the sole 2 are connected by a hinge 8. The front part 3 has of the sole 2 is provided with an upper shoe 5. The back part 4 of the sole 2 is provided with an upper shoe 6. The front upper shoe 5 and the back upper shoe 6 have an interface 9. Through the interface 9 fluid or dirt may enter the shoe. This is undesirable.
When the shoe 1 is opened, as shown in figure 2, by turning front part 3 of sole 2 relative to back part 4 of sole 2, between the edge 11 of the front upper shoe 5 and the edge
10 of the back upper shoe 6, an opening 7 will arise.
Consequently the entrance of the shoe 1 becomes larger and stepping in and out is accordingly facilitated and eased. When the shoe is closed again, objects, such as parts of the foot, fingers or socks, may become trapped between the edges 10 and
11 at the interface 9.
The shoe 1 according to the invention as shown in figure 3 is provided with a seal 12. The seal 12 covers the interface 9, preventing liquids and dirt entering the shoe 1. The seal 12 is, in this case, provided at the inside of the shoe 1, however, may within the scope of the invention also be provide at the outside of the shoe 1. When positioned outside the shoe 1, such seal 12 may have a material, look and color matching that of the shoe 1, in order to have a fashionable design. The seal 12, made of a resilient stretchable fabric, may for instance be stitched or bonded to the shoe 1. The fabric comprises polyurethane . For instance Lycra would be a suitable fabric. The seal 12 has a converging sides 13 and 14. The sides 13 and 14 of the seal 12 converge with an included angle a, which angle is more or less similar to the angle over which the shoe 1 will be opened. The broader part of the seal 12 is located at distance of the hinge 8, where the narrow part of seal 12 is located nearer to the hinge 8. According to the invention the broader part of the seal 12 has preferably a width in the range of 65 to 95 mm, where the narrow part of the seal 12 has a width in the range of 5 to 20 mm. The top of the seal 12 is according to the invention preferably located in a range of 20 to 40 mm distance from the hinge. As most shoes, besides the differences in size in longitudinal direction, are shaped according to a more or less uniform system, the
mentioned ranges will be optimal for most shoes. It is however clear that, within the teachings of the present invention, for different types of shoes different optimizations may be found and applied.
As can be seen in figure 4, where the shoe is in open position, the seal 12 seals a substantial part of the opening 7 of shoe 1. When the shoe 1 would be closed again the seal 12 will prevent objects to be trapped between the edges 10 and 11. The shape of the seal 12 with the converging sides 13,14 and the broader part at a distance of the hinge, make it possible that the seal 12 is stretched over a larger distance further away from hinge 8. The converging angle a similar to the opening angle of the shoe 1, facilitates opening of the shoe 1 to its maximum. All this will result in an even stress
distribution in the seal 1 and the seal 1 will be stretched uniformly .
In figure 5 an embodiment of the invention with an additional seal 15 is shown. The shoe 1 of figure 5 is in fact similar to that of the figures 3 and 4. As the seal 12 of shoe 1 is provided at the inside of the shoe 1, still some liquid or dirt may penetrate at the interface 9 and may pollute or wet seal 12 from the outside. Although liquids and dirt will be prevented by seal 12 from penetrating the shoe 1, pollution and wetting of the seal is for some applications less desirable. Therefore an additional seal 15 has been provided to the shoe 1 between the edges 13 and 14 of the interface 9. The seal is resilient compressible in order to have and maintain good sealing properties. In this specific embodiment the seal 15 consists of two complementary parts, a first part 16 at the edge 11 and a second part 17 at the edge 10.
In figure 6 and 7 a shoe without laces is shown. The shoe 1 is in the sole 2 provided with a hinge. The hinge has an axis 8, around which the front part 5 and the back part 6 may turn relative with respect to each other. The hinge is designed such that it has two stable positions. In a first position the shoe 1 is closed and locked and provides an optimal wearing comfort. In the second stable position the shoe 1 is open. The shoe may be entered by a foot without using hands and without the risk that the shoe closes unintended. The front part 5 of shoe 1 is provided with extensions 18. These extensions 18 internally extend the shoe along the back part 6 of shoe 1.
Within the scope of the invention, an alternative embodiment may be that an extension 18 extends at the outside along the back part 6 of the shoe 1. Similar, the extensions may be provided on the back part 6 of shoe 1. In open position of the shoe 1 the extensions 18 close the space between the edges 10 and 11. In closed position of the shoe 1, the foot in the shoe 1 will push the extension 18 against the inside of the back part 6 of the shoe 1. In the way a tight seal is obtained. The interacting surfaces of the extensions 18 and the back part 6 may be provided with resilient compressible material in order to further enhance the sealing characteristics and the wearing comfort. For some applications it will be desirable to isolate the internal shoe from the external shoe. In that case an additional seal-element may be provided between the top of the extension 18 and the edge 10 of the back part 6 of shoe 1.
Typically this will be a flexible folding seam, made of suitable fabric or plastic sheet. Preferably a thin sheet will be applied to enhance the wearing comfort. The wearing comfort may be further enhanced by using a suitable folding pattern. Such suitable folding pattern will also facilitate the folding and unfolding of the flexible folding seam when opening and closing the shoe 1. The shoe 1 is at the edge 10 of back part 6 also provided with stiffening means 19. These stiffening means 19 will provide additional stiffness to the shoe in the area of the hinge and additional support to the foot. It will be clear that within the scope of the invention several types of
stiffening means may be applied and that also the front part 5 of the shoe may be provided with stiffening means 19. In particular also both edges 10 and 11 may be provided with stiffening means.
To the person skilled in art it is obvious that the above given embodiments represent only a few of the many possible
variations in which the shoe according to the invention may be embodied. Therefore the embodiments given here must be
understood as an elucidation to the appended claims without limiting the scope of the invention. Within the protective scope numerous variations are conceivable. For instance, the seal 15 may also be applied independent of seal 12. The seal 15 provides, in closed position of the shoe, sufficient sealing properties in order to prevent penetration of dirt and liquids. Further, the seals may according to the invention run from the medial side to the lateral side of the shoe. In this way, with just one seal, both interfaces of the shoe, at the medial and the lateral side, may be sealed. Running over the sole the same seal may also seal the sole, in particular near the hinge.
