The present invention relates to a baseplate for a shoe, in particular a sports shoe, a shoe upper, which is suitable for the reception of the baseplate, a shoe, comprising the baseplate and the shoe upper, and a manufacturing method for each of the above.
Shoes, in particular sports shoes generally comprise a shoe upper and a sole attached thereto. The sole supports a foot of a wearer of the shoe, transmits forces from the foot to the ground and provides—depending on the intended use of the shoe—a certain amount of damping. Generally, the sole comprises a tread on its outer side, to increase the friction with the ground and to prevent an unwanted slipping of the shoe. The latter aspect is particularly relevant for sports shoes.
Sports shoes thus often comprise special treads which are adapted to the respective sport. For example, football and rugby boots often comprise studs which engage in the comparable soft ground (e.g. grass) and hence enable a large degree of traction. In sprint shoes spikes are used as tread elements which penetrate the surface of a running track in order to prevent slipping of the runner. Likewise, golf shoe comprise so called “spikes” which significantly increase the traction of the shoe in particular on grass due to their design.
The U.S. Pat. No. 7,730,637 B2 refers to a modular shoe which comprises a shoe upper with an upper side and a bottom side, a chassis releasably arranged inside the shoe upper, and a plurality of studs. Each stud is releasably attached to the chassis through the bottom side of the shoe upper. The bottom side of the shoe upper is clamped between the chassis and at least one of the attached studs.
The FR 2 813 766 refers to a shoe which comprises a sole with heightened sections below the sole and the heel. The shoe upper comprises openings in its bottom side, in which these heightened sections fit.
The U.S. Pat. No. 997,657 refers to a sports shoe or slipper with a solid outer sole which comprises a plurality of openings in its tread section and is equipped with a releasable and renewable tread element with a section, which is arranged in such a way to cover the inside of the outer sole tread section and which comprises pads that fit into the openings and protrude through the openings up to the outside of the outer sole.
The U.S. Pat. No. 8,813,387 B2 refers to an article of foot wear which includes a shoe upper and a sole structure. The shoe upper defines an internal cavity which is arranged to receive the sole structure and a foot. A lower surface of the shoe upper defines a plurality of openings and the sole structure includes a plurality of protrusions which protrude through the openings to form a ground contacting surface.
The WO 97/46127 refers to a method for the manufacturing of a shoe which includes the forming of a shoe upper, wherein the shoe upper includes a plurality of openings at its bottom side as well as an inner foot-shaped cavity. Next, a shoe outer sole is inserted into the inner cavity, so that sections of the outer sole protrude from the openings in the shoe upper and form an outer contact face of the shoe. The outer sole is connected to the shoe upper by gluing and/or stitching.
A disadvantage of known shoes, in particular sports shoes, is that they do not have a tread adaptable to the ground. Furthermore, another disadvantage is the weight of conventional shoes, in particular sports shoes, despite the effort for weight reduction, still comparably high. At the same time in shoes which are optimized with regard to their weight, the foot of a wearer is often not sufficiently supported.
The present invention relates to the problem to overcome the mentioned disadvantages of known shoes, in particular sports shoes.

According to certain embodiments of the present invention, a modular shoe component comprises a baseplate comprising an upper surface for supporting the foot of a wearer and a bottom surface comprising one or more tread elements integrally formed with the baseplate, and a shoe upper for receiving the foot of a wearer comprising a bottom surface with one or more openings, wherein the baseplate is insertable into the shoe upper and the baseplate and the shoe upper are configured to allow the one or more tread elements each to project through the one or more openings of the shoe upper.
In some embodiments, the baseplate is removable from the shoe upper. The baseplate, in certain embodiments, is configured to cover substantially all of the bottom portion of the shoe upper
The following detailed description, embodiments of the invention are described referring to the following figures:
According to the invention a baseplate for a shoe, in particular a sports shoe, is provided, wherein the baseplate is suitable to be inserted removably into a shoe upper, and wherein the baseplate comprises: (a.) a plate-shaped, stiff and rigid body which is suitable to provide stability to the shoe upper, (b.) a plurality of tread elements which are suitable to protrude through respective openings in a bottom portion of the shoe upper, if the baseplate is inserted into the shoe upper, (c.) wherein the tread elements are formed in one piece with the body.
Due to the fact that the baseplate is removably inserted into the shoe upper, another baseplate may be inserted into the shoe upper e.g. depending on the ground condition. In a football boot, a baseplate with relatively few but long tread elements in the shape of studs may be inserted, for example for the use on a grass field. On a cinder field however, a baseplate with relatively many, but preferably shorter, tread elements may be used. In some embodiments of the invention the baseplate is thus suitable to be inserted into a shoe upper of a football boot.
The arrangement and condition of the tread elements can furthermore be adapted depending on the requirements of the wearer of the shoe. In this manner, the shoe may be easily individualized regarding its tread-structure, wherein the same shoe upper may be used.
The baseplate according to the invention furthermore allows to provide a relative lightweight shoe which also supports the foot of a wearer sufficiently. A shoe comprising the baseplate according to the invention may comprise only the shoe upper and the baseplate. Given that the baseplate provides the necessary stability to the shoe and supports the foot of a wearer sufficiently due to its material properties, further components may be omitted, whereby the shoe becomes particularly lightweight. By way of example, the baseplate according to certain embodiments may comprise a flexural modulus of elasticity of at least 1000 N/mm2, and further of at least 1200 N/mm2. Furthermore, the baseplate comprises in some embodiments a drag modulus of elasticity of at least 1000 N/mm2, and further of at least 1700 N/mm2. A tensile strength of the baseplate is at least 40 N/mm2, and further is at least 45 N/mm2. A Charpy impact strength of the baseplate is at least 40 kJ/mm2, and further is at least 53 kJ/mm2.
The baseplate can extend throughout from a heel region of the shoe upper to a toe region of the shoe upper. Hereby the foot of a wearer is persistently supported. Further components, for example outer or midsoles, may be neglected if desired.
One of the plurality of tread elements may comprise an undercut for the reception of a section of an edge of an opening in the bottom portion of the shoe upper to fix the tread element relative to the bottom portion of the shoe upper. By this measure it may be prevented that the bottom portion of the shoe upper slips accidentally over at least one of the tread elements. Furthermore, a slipping of the baseplate in the shoe upper is prevented or at least the likelihood of such slippage is reduced.
The undercut may be a circumferential groove in the at least one tread element. A circumferential groove enables the fixation of the bottom portion of the shoe upper on all sides of the respective tread element.
The baseplate and/or the entire shoe may be manufactured in a 3D-printing process. With regard to the present invention, 3D-printing has the advantage that a baseplate individualized for the wearer of the shoe may be manufactured easy and cost-efficient. For example, the wearer of the shoe can design the tread-structure, i.e. the arrangement and size of the tread elements, by himself Another advantage of the 3D-printing is that the previously mentioned undercut may be created during the printing. Additional production steps, as for example milling, are not necessary.
The arrangement, the respective height and the respective circumference of the tread elements may be adapted to the ground on which the shoe is used. The shoe thus has the best possible traction on each ground.
A first subset of the plurality of tread elements may be studs and a second subset of the plurality of tread elements may be plugs. The plugs can comprise such a height in comparison to the studs that the studs are able to contact a flat ground, the plugs however not. The plugs prevent an intrusion of water and dirt from the bottom into the shoe upper, while the studs provide the necessary traction. In each of the openings of the bottom portion of the shoe upper can either be a stud or a plug.
The plugs may be suitable to close the openings in the bottom portion of the shoe upper through which they protrude. In this manner, an intrusion of water and dirt is prevented at the best. If another baseplate is inserted, for example a stud can protrude through the same opening which was closed by a plug before.
The studs may be suitable to close the openings in the bottom portion of the shoe upper through which they protrude as well. In this manner, an intrusion of water and dirt is prevented.
In general, according to the invention, each tread element may correspond to a certain opening in a bottom portion of a shoe upper, such that there is a one-to-one correspondence between the tread elements and the openings.
At least one stud may comprise at least one groove extending in a vertical direction and being suitable to interact with a corresponding lug of a stud key. Such a stud key may be used to clamp the bottom portion of the shoe upper in an undercut as will be described in more detail herein. The stud key may comprise at least one lug interacting with the groove. Thus, the groove may provide the function of a guiding means for the stud key.
The baseplate can comprise further a mounting device to fix the baseplate to the shoe upper. A slipping of the baseplate in the shoe upper is thereby reduced or prevented.
The mounting device may be at least a screw or a hook-and-loop tape. These types of mounting devices are easy to handle and fix the baseplate reliable.
The baseplate and/or the shoe upper may be equipped at least in parts with an anti-slip textile. Consequently a relative movement between the baseplate and the shoe upper may be prevented further. The anti-slip textile may be disposed in a forefoot region of the bottom portion of the baseplate and/or the shoe upper. In other examples another slip resistant element, e.g. a rubber element, may be provided.
The baseplate may be made of polyamide, polyether-block-amide (PEBA) or thermoplastic polyurethane (TPU). These materials are easy available and enable the manufacturing of a very durable baseplate. The baseplate may be made in particular of powdered polyamide 12. Elements made of polyamide 12 resist high mechanical or thermal strains. Furthermore, elements made of polyamide 12 provide the above mentioned material properties for example with regard to drag modulus of elasticity, tensile strength or flexural modulus of elasticity.
The baseplate can comprise at least an opening and/or a cavity. The opening and/or cavity could generally overlap with an opening in the bottom portion of the shoe upper or cover such an opening. In an overlap, air could stream from the outside of the shoe upper into the inside and vice versa to vent the foot.
The baseplate can also comprise regions with variable material thickness. So, there may be first regions which are thinner than second regions. Such thinner regions can serve to reduce a flexural strength or a stiffness in these regions.
A further aspect of the present invention relates to a shoe upper for a shoe, in particular a sports shoe, wherein the shoe upper is suitable for the reception of a baseplate as described before, and comprises a bottom portion with regions, wherein each of the regions comprises at least an opening, and each of the regions is more elastic than other regions of the bottom portion.
Due to the fact that the regions around the openings are more elastic than other regions of the shoe upper, the bottom portion of the shoe upper can close particularly well with the tread elements, which protrude through the openings. In this manner, on the one hand the intrusion of water and dirt may be prevented and on the other hand the baseplate is particularly well fixed relative to the shoe upper.
The regions of variable elasticity may be realized for example by means of a multi-layer structure of the bottom portion of the shoe upper. So, the bottom portion can comprise a base layer made of synthetic polyurethane, textile or knitted fabrics. On this base layer a top layer may be disposed, for example by means of HF bonding or heat compression molding. The base layer comprises the openings. If the top layer is omitted in regions around the openings, the regions of variable elasticity may be created particularly facile. The base layer has thereby a higher elasticity than the top layer. The top layer can comprise for example a TPU foil to increase an abrasion resistance of the bottom portion. It is also possible that more than three layers are disposed on top of each other to create the bottom portion.
Each of the openings in the bottom portion of the shoe upper can comprise a smaller diameter than the respective tread element, which protrudes through the respective opening, if the exchangeable baseplate is inserted into the shoe upper. Hereby the elastic regions are stretched and lie particularly tight to the tread openings, whereby the closure effect is strengthened even more.
The elastic regions may be arranged such that there are less elastic regions between elastic regions. The less elastic regions provide for that the bottom portion of the shoe upper is not stretched too much on the whole if the shoe is worn.
Each region may comprise one opening, such that there is a one-to-one correspondence between the tread elements and the regions.
Besides the bottom portion the shoe upper comprises an upper portion which encloses the foot of the wearer. The bottom portion and the upper portion may be manufactured independent of each other and permanently connected to each other afterwards. Such a connection may be achieved for example by means of sewing engineering or pinching. The shoe upper may be formed basically in two parts comprising the bottom and the upper. The bottom portion and the upper portion may be formed as well in one piece from the same material.
Yet a further aspect of the present invention relates to a shoe, in particular a sports shoe, which comprises a shoe upper and a baseplate as described before. As already explained, in the shoe according to the invention another baseplate may be inserted into the shoe upper, e.g. depending on the ground condition. Furthermore, according to the invention, a relative lightweight shoe may be provided which however supports the foot of a wearer sufficiently.
Still a further aspect of the present invention relates to a set of baseplates for a shoe, in particular a sports shoe, wherein each baseplate is formed as described before, and each baseplate in the set of baseplates is different to every other baseplate in the set of baseplates at least in the arrangement and the design of the tread elements.
The wearer of a shoe in whose upper one of the baseplates is inserted, can thus chose an appropriate baseplate, depending on the personal preferences or the ground condition, and insert it into the shoe upper. For example, in a set of baseplates for a football boot one baseplate at a time may be suitable particularly well for grass fields, one for cinder fields, one for sports halls, etc.
A distribution channel and a business model respectively of the baseplate according to the invention, the shoe upper according to the invention and the shoe according to the invention can include a separate sale of the individual components. The shoe upper can thereby directly adapted to a sportsperson and may be sold directly to him or her. Moreover separately a plurality of baseplates may be offered for sale separately. The baseplates may be sold separately or in sets. The baseplates can differ in particular with regard to the number and type of the tread elements, material, material constants, configuration in terms of color or graphical design. A customer who already bought a shoe upper separately, can buy at least one baseplates according to personal desires. It is also possible that a shoe upper is distributed together with a baseplate or a set of baseplates.
The baseplates may be printed either at home by the sportsperson him- or herself by means of a 3D-printer, may be ordered by the sportsperson online or may be bought in a shop. It is also possible that the baseplates may be created, in particular 3D-printed, in a shop immediate according to the customers or sportspersons desire. The baseplates may be supplied plain-colored or multi-colored and may be provided with design elements, for example by means of coating, flocking, laminating, sprinkling, bonding and/or printing, in the shop or by an end-user.
Yet, a further aspect of the present invention relates to a method for the manufacturing of a baseplate as described before, wherein the method comprises the steps: (a.) forming the plate-shaped body of the baseplate, and (b.) forming the plurality of tread elements in one piece with the body, so that the tread elements are suitable to protrude through the respective openings in the bottom portion of the shoe upper, if the complete baseplate is inserted into the shoe upper.
The baseplate may be manufactured in a 3D-printing process.
The baseplate can also be manufactured in an injection molding process. In such an injection molding process spacing elements in the shape of a ring-disk are inserted between tread elements and baseplate for creating the undercuts. Thereby at first the tread elements are produced, in some embodiments, of TPU. Afterwards the ring-disks are mounted to the tread elements. The ring-disks are thereby mounted in a region of the tread elements that is located adjacent to the baseplate to be injection molded. For the mounting of the ring-disks for example a pen-like protrusion of the tread elements is suitable. Afterwards the baseplate, in some embodiments made of PA, is injection molded to the tread elements. By the arrangement of the ring disks between tread elements and baseplate the undercuts are created. After the injection molding of the baseplate the ring disks may be removed again. It is in principle also possible to produce the baseplate at first and afterwards injection mold the tread elements to the baseplate, by use of the ring disks.
The ring disks are in some embodiments made of a material which does not tend towards bonding with the material of the baseplate or the tread elements. Such a material is for example Teflon.
The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.
The baseplate 11 may be made of plastic material as for example polyamide, polyether-block-amide (PEBA) or thermoplastic polyurethane (TPU). The baseplate 11 may be manufactured e.g. by means of an injection molding or by means of a 3D-printer.
According to certain embodiments, as shown in
The tread elements 13, 13a and 13b are formed in one piece with the body 12. For example, the tread elements 13, 13a and 13b may be formed in one piece with the body 12 by means of an injection molding. In case a 3D-printer is used for the manufacturing of the baseplate 11, the tread elements 13, 13a and 13b are formed in one piece with the body 12, by forming the baseplate 11 layer by layer in the printer.
In some embodiments, the baseplate 11 comprises two different types of tread elements. A first subset of the plurality of tread elements are studs, of which two are labeled with the reference sign 13a. The second subset of the plurality of tread elements are plugs, of which two are labeled with the reference sign 13b. In general, according to the invention, each stud 13a and plug 13b may correspond to a certain opening in a bottom portion of a shoe upper as will be described in more detail below.
The studs 13a are frustum-shaped in certain embodiments, as shown in
Generally, the arrangement, the respective height and the respective circumference of the tread elements 13, 13a and 13b may be adapted to the ground on which the shoe, in whose upper the baseplate 11 is inserted, is used. For example in a football boot a baseplate with few, but instead relative long studs may be inserted, if the football boot is used on a grass field. In using the football boot on a cinder field a baseplate with many, but instead shorter studs may be inserted.
At least one of the plurality of tread elements 13, 13a and 13b can comprise an undercut for the reception of a section of an edge of an opening in the bottom portion of the shoe upper to fix the tread element relative to the bottom portion of the shoe upper. This is true for the embodiments of the tread elements of
The undercuts 14 can for example be milled into the respective tread elements, for example if the baseplate 11 is manufactured by means of an injection molding.
The undercuts 14 can also be created in a multi-stage injection molding, as shown in
In certain cases, manufacturing of the baseplate 11 (and/or the entire shoe) with a 3D-printer may be beneficial because, in this case, the undercuts 14 may be created during the printing process, and without that, a further production step (e.g. milling) is necessary.
The
The regions 33 may be connected or separated from each other. If the regions 33 are separated from each other, there is at least one other less elastic region 35 between two elastic regions 33. In certain embodiments, each of the regions 33 may be assigned to one certain stud 13a or plug 13b, i.e. each region 33 comprises exactly one stud 13a or plug 13b.
The shoe upper 31 is suitable to receive a baseplate 11, as it was described before with reference to the
In order to fix the baseplate 11 to the shoe upper 31, the baseplate 11 can comprise a mounting device (not shown in the Figs). The mounting device may be for example a screw, textile material, rubber material or a hook-and-loop-tape. If a screw is used, a respective screw thread may be located in the bottom portion 32 of the shoe upper 31, in which the screw is screwed, to fix the baseplate 11 between the screw head and the bottom portion 32 of the shoe upper 31. Alternatively, the screw thread may be located in the baseplate 11 and the screw is screwed into the screw thread through an opening in the bottom portion 32 of the shoe upper 31 to fix the bottom portion 32 of the shoe upper 31 between the screw head and the baseplate 11. If a hook-and-loop tape is used as a mounting device, the baseplate 11 can comprise a hook-and-loop tape at its bottom portion, and a respective counterpart may be at the bottom portion 32 of the shoe upper 31 inside the shoe upper 31.
The
The
If the baseplate 11b is inserted into the appropriate shoe upper 31 for a football boot, the respective football boot would be particularly well suited for a soft ground, as for example a grass field. The baseplate 11c comprises three different types of tread elements, namely long studs 13a, plugs 13b and short studs 13d. The baseplate 11c would be suitable for a football boot which is used on medium-hard up to hard ground. The baseplate 11d comprises two different types of tread elements 13, namely long studs 13a and short studs 13d. The baseplate 11d is suitable for a football boot which is used on medium-hard up to soft ground.
According to the invention, the wearer of a shoe 41 according to the invention can thus change the baseplate 11 depending on the condition of the ground on which the shoe 41 is worn. It is also possible to change the baseplate 11 at the time when the tread elements 13 are worn out due to abrasion up to a certain degree.
The
The
The openings 81 can also provide for adjusting the stiffness of the respective baseplate 11e, 11f, 11g and 11h. For example, the baseplate 11h has a lot of openings 81 in the forefoot region. This increases the flexibility of the baseplate 11h in the toe region and enables a more facile rolling up of the foot. The shoe upper 11f shown in
The baseplates 11e, 11f, 11g and 11h can also comprise regions with variable material thickness, in particular cavities, instead of openings. Thus, first regions may be provided which are thinner than second regions. Such thinner regions can provide for reducing a flexibility or a stiffness in these regions.
As shown in
What has been said above with respect to a stud 13a is valid for a plug 13b as well, i.e. the stud key 101 may be used as well to clamp the bottom portion 32 of a shoe upper under the undercut of a plug 13b. Alternatively, a separate plug key may be used with a shape that is especially adapted to fit a plug 13b.
Generally, features of different exemplary embodiments described herein may be combined to obtain a further embodiments of the present invention.
In the following, further examples are described to facilitate the understanding of the invention:
Different arrangements of the components depicted in the drawings or described above, as well as components and steps not shown or described are possible. Similarly, some features and sub-combinations are useful and may be employed without reference to other features and sub-combinations. Embodiments of the invention have been described for illustrative and not restrictive purposes, and alternative embodiments will become apparent to readers of this patent. Accordingly, the present invention is not limited to the embodiments described above or depicted in the drawings, and various embodiments and modifications may be made without departing from the scope of the claims below.
