Description

Last for manufacturing an orthopaedic shoe

The present invention relates to a last for manufacturing an orthopaedic shoe. The present invention further relates to a core and shaped-portion for use in the last of the present invention as well as a method for manufacturing an orthopaedic shoe. The present invention further relates to a method and kit for manufacturing the last of the present invention.

The manufacturing of shoes is a well-known process. The fundament for the manufacturing a well-fitted shoe is the last. A conventional last may be used for the production of ready-to-wear shoes, however, one could opt for the manufacturing of personalized hand crafted, bespoke lasts enabling the shoemaker to create a perfect-fitted shoe for an individual.

In case the shoe wearing individual is suffering from foot deformity, e.g. flat feet, hammertoe, stiff big toe, or the like, the manufacturing of a well-fitted shoe is a much more complex process. It has to be understood that the degree of deformity of the foot one-to-one correlates with the complexity of the shoe manufacturing process.

Nowadays, the individual suffering from foot deformity has three available options to select the best-fitted shoe.

The first available option is to select a conventional, ready-to-wear shoe, which shoe is further adapted to improve the fit of the shoe. The second available option is a more made-to-measure procedure, wherein the individual is able to select a predefined shaped shoe, i.e. a predefine base, upon which the shoe manufacturer further adapted the shoe to be manufactured based upon the preferences of the individual suffering from foot deformity. As a third available option, the individual suffering from foot deformity may opt for a custom made shoe based upon a custom made last, i.e. bespoke last.

The pros and cons of each of the available options are different. For example, the adaptation of a ready-to-wear shoe provides a cost efficient method. However, since the ready-to-wear shoe needs to be adapted the materials used for manufacturing the shoe limits the collection of available adaptable ready-to-wear shoes. In case non-flexible materials are used, the level of adaptation is limited compared to ready-to-wear shoes wherein flexible materials are used. Inherently, the degree of adaptation of the ready-to-wear shoe is limited as such. Therefore, this first option is available only for individuals suffering from a foot deformity wherein the degree of deformity still closely resembles the shape of a normally shaped foot. Similar advantages and disadvantages can be mentioned with regard to the second available option. Although the shoe is manufactured based upon the specific preferences of the individual suffering from foot deformity, the basis of the shoe is still selected using a standard shoe fit wherein space is provided for further adaptation of the shoe. It is noted that this second option is still cost effective, however, the resulting shoe does not perfectly fits the deformed foot of the individual. Although the third available options results in a shoe which perfectly fits the deformed foot of the individual, the manufacturing (and storage) of a custom made last is a labour intensive process and consequently a much more costly procedure.

Furthermore, the currently available options still have limited flexibility with regard to the final form of the shoe. For example, the custom made last must be able to be removed from the manufactured shoe. As a consequence, the form and shape of the last is adapted such that the last can be removed from the shoe. Protruding parts in, for example, the toe portion and/or heel portion, e.g. the contrefort, are not allowed since such protruding parts prevent the last to be removed from the shoe once manufactured. Further adaptation of the last may have a negative effect on the actual fit of the shoe on the deformed foot.

Therefore, given the available options above there is a need for providing an improved method for manufacturing an orthopaedic shoe wherein the inner dimensions of the shoe can be varied without being restricted in design of the last.

The present invention provides hereto a last for manufacturing an orthopaedic shoe, comprising a core arranged for receiving at least one shaped-portion defining at least a part of the inner dimensions of the shoe to be manufactured and at least one shaped-portion, which shaped-portion being self-releasably and/or detachably connected to the core. The at least one shaped-portion defines an aberrant shaped part of the inner dimensions of the shoe to be manufactured such that the at least one shaped-portion being removable from the shoe to be manufactured in case the at least one shaped-portion is disconnected with the core. It was found that by providing a last assembled by differently shaped parts, e.g. a modular last, wherein at least one of the shaped parts defines an aberrant shaped part, i.e. a part deviating from the normal, conventional, shape of a shoe, a last can be provided which can still be released from the shoe to be manufactured without unnecessarily deforming the material the shoe is made of.

Even further, by providing a last according to the present invention, the shoemaker has the possibility to vary the shape of the last to be used, without the need of manufacturing a single last for one single orthopaedic shoe to be manufactured. Therefore, the present invention provides a last wherein a great variety of shapes can be provided using just one single core, e.g. main last body. By providing a modular last, the last of the present invention can be efficiently stored.

The core of the last of the present invention may have any shape as long as the core is arranged to receive at least one shaped-portion. It has to be understood that surface of the last of the present invention may be formed by shaped-portions only, i.e. the shaped-portions defining the complete inner dimensions of the shoe to be manufactured. However, in an embodiment of the present invention, the core may define at least a part of the inner dimensions of the shoe to be manufactured. In this way, the core may be shaped such that the main shape of the inner dimensions of the shoe to be manufactured is defined by the core and that the shaped-portions are used only for defining aberrant shaped parts of the inner dimensions of the shoe to be manufactured. For example, the core may define the inner dimensions of the insole, e.g. arch.

In order to provide a last for manufacturing a shoe wherein the surface of the last is smooth without any (sharp) edges or roughening, the at least one shaped-portion may be at least partially shape-fitted coupled to the core. Particularly in case the core defines a part of the inner dimensions of the shoe to be manufactured, a shape-fitted coupling is preferred to prevent irregularities on the surface of the assembled last. Due to the aberrant shape of the at least one shaped-portion of the last of the present invention, the shaped-portion will be retained in the manufactured shoe in case the core is removed first from the manufactured shoe. Since, the aberrant shape will cause the shaped-portion to be retained in the shoe, no further edges or irregularities in the shape of the last are needed to retain the shaped-portion in the manufactured shoe.

As it is defined above, the core of the last of the present invention is arranged for receiving at least one shaped-portion such that the at least one shaped-portion is self-releasably and/or detachably connected to the core. Any coupling means known in the art may be used as long as the at least one shaped-potion is self-releasably connected to the core in case the core is removed first from the shoe to be manufactured before removing the shaped-portion. Alternatively or additionally, the coupling means are chosen such that the shaped-portion is detached to the core in case the shaped-portion is removed first from the shoe to be manufactured before removing the core of the last. It is noted that the core itself may function as a coupling means as a whole in case the inner dimensions of the shoe to be manufactured are defined by shaped-portions only.

Preferably the core is provided with at least one receiving part for receiving the at least one shaped-portion. For example, the core and the at least one shaped-portion may be fitted together by providing a core comprising one or more pins, which one or more pins fit into respective bores provided in the at least one shaped-portion. Inherently, the core may be provided with bores wherein respective pins provided onto the at least one shaped-portion may be fitted in. In a preferred embodiment of the present invention, the receiving part of the core is a recessed part wherein the at least one shaped-portion may be recessed. Preferably, the at least one shaped-portion may be recessed into the recessed part of the core such that the at least one shaped-portion is at least partially shape-fitted placeable over the at least one receiving part, i.e. that the surface of the at least one shaped-portion is shape-fitted coupled with the surface of the core.

In a further embodiment of the last of the present invention, the at least one shaped-portion partially encloses the at least one receiving part. It is noted that the at least one shaped-portion may be positioned such that at a certain cross-section a part of the contour of the last according to the present invention is formed by the at least one shaped-portion wherein the other part of the contour is formed by the core. It may be further advantageous to provide at least one shaped-portion which encloses the at least one receiving part such that at a certain cross-section of the last according to the present invention the contour of the last is entirely defined by the at least one shaped-portion, i.e. a cross-section of the last wherein the core is formed by the core of the last according to the present invention and the outer surface is defined by the at least one shaped-portion.

The at least one shaped-portion, being an aberrant shaped-portion, used in the last of the present invention is self-releasably and/or detachably connected to the core such that the at least one shaped-portion being removable from the shoe to be manufactured in case the at least one shaped-portion is disconnected with the core. It was found that by removing the main part of the last, i.e. the core and optionally other aberrant or non-deformed shaped-portions connected to the core, the retained at least one shaped-portion can be removed by changing the spatial orientation of the shaped-portion, e.g. by turning, twisting, wringing or the like.

In a preferred embodiment, the at least one shaped-portion is deformable to provide a more easy release of the at least one retained shaped-portion from the shoe to be manufactured. To this end, the at least one shaped-portion may be provided with hinges, folding lines or the like. In a further preferred embodiment, the at least one shaped-portion is made of flexible material. By providing an at least one shaped-portion made of flexible material, the at least one retained shaped-portion may be removed from the manufactured shoe by squeezing the shaped-portion once the core is removed. In case the shaped-portion defines at least a part of the heel portion of the last, e.g. the contrefort comprising a protruding part, the shaped-portion made of flexible material may be removed from the shoe by sliding the shaped-portion over the last into the direction of the toe portion, thereby disconnecting the shaped-portion from the core, and subsequently removing the shaped-portion from the manufactured shoe. By sliding the shaped-portion into the direction of the toe portion, i.e. in longitudinal direction of the shoe, the protruding part of the aberrantly shaped-portion is moved into an inward direction to be able to remove the shaped-portion from the heel portion, i.e. perpendicular to the longitudinal direction of the shoe.

The flexible material of which the shaped-portion may be made may be selected from any suitable flexible material. Preferably, the properties of the flexible material are chosen such that in case the at least one shaped-portion is connected to the core to form the last of the present invention, the flexible material is not, or only slightly, compressible to ensure a certain firmness of the last to be used for manufacturing the orthopaedic shoe. Once the at least one shaped-portion is disconnected to the core, the at least one shaped-portion should be compressible to enable easy removal of the at least one shaped-portion from the manufactured shoe. An example of a flexible material which possesses the above-defined properties is nylon.

As already mentioned above, the at least one shaped-portion may define at least a part of the inner dimensions of the toe portion and/or heel portion of the shoe to be manufactured. In particular, the shape of the toe portion and heel portion, e.g. the contrefort, determines a perfect fit of the shoe since those parts provide the necessary firmness of the shoe which is of major importance for the perfect fit. In case of an individual suffering from a foot deformity wherein the aberrant shaped part of the foot is located in the toe portion and/or heel portion, e.g. the contrefort, of the shoe, the essential firmness of both parts of the shoe limits the possibilities of the shoemaker in designing the perfect last. Indeed, the last should be designed such that the deformed part of the last can be removed from the perspective portion (or portions) without reducing the firmness of the toe portion and/or heel portion, e.g. the contrefort.

To overcome this problem, the present invention provides a modular last as defined above, wherein the at least one shaped-portion defines at least a part of the inner dimensions of the toe portion of the shoe to be manufactured and wherein the at least one shaped-portion being self-releasably coupled to the core. Since the shoemaker is not able to access the at least one shaped-portion defining the toe portion of the shoe to be manufactured, the at least one shaped-portion should be self-releasably coupled to the core. By providing such a shaped-portion, the shaped-portion is retained, due to the aberrant shape of the shaped-portion, into the manufactured shoe by removal of the core from the manufactured shoe. Subsequently, the at least one retained shaped-portion is removed from the shoe by the shoemaker.

Alternatively or additionally, the present invention provides a modular last as defined above, wherein the at least one shaped-portion defines at least a part of the inner dimensions of the heel portion, such as the contrefort, of the shoe to be manufactured and wherein the at least one shaped-portion being self-releasably and/or detachably coupled to the core. Since the at least one shaped-portion defining the inner dimensions of the heel portion may be accessibly by the shoemaker, the last of the present invention may be designed such that the shoemaker should first remove the aberrant shaped-portion before removing the core from the manufactured shoe. As already explained above, the aberrant shaped-portion may be detached from the core by moving the shaped-portion in an inward direction, sliding the shaped-portion between the inner surface of the manufactured shoe and the outer surface of the last. To be able to slide the shaped-portion into the direction of the front part of the shoe, the shaped-portion defining at least a part of the heel portion may be provided with an empty internal space which may be filled by the core of the last once the shaped-portion is slid into the direction of the toe portion. It is noted that the aberrant shaped-portion defining at least a part of the inner dimensions of the heel portion, such as the contrefort, may be self-releasably connected to the core as well to allow removal of the core first, followed by removal of the aberrant shaped-portion.

In an embodiment of the last of the present invention, the core is arranged to receive two or more shaped-portions, wherein the two or more shaped-portions define at least a part of the inner dimensions of the toe portion and the heel portion of the shoe to be manufactured. In particular, the last of the present invention comprises a core arranged to receive a shaped-portion defining the toe portion of the shoe to be manufactured as well as a shaped-portion defining the heel portion of the shoe to be manufactured. Since both portions are that critical in designing a perfect fitting shoe, a last arranged to receive at least those two kind of shaped-portions offers a great variety in the design of perfect fitting shoes.

In a further embodiment of the last of the present invention, the at least one shaped-portion coupled with the core defines the inner dimensions of the shoe to be manufactured, which inner dimensions correspond with the contours of a foot of a person suffering from foot deformity. The foot deformity may be selected from the group consisting of hallux valgus, hallux rigidus, pes planus, Haglund’s deformity and combinations thereof.

It is noted that the at least one shaped-portion coupled with the core to define the inner dimensions of the shoe to be manufactured and wherein the inner dimensions correspond with the contours of a foot of a person suffering from foot deformity may be selected from a collection of shaped-potions, such that the selected shaped-portion closely resembles at least a part of the contours of a foot of a person suffering from foot deformity. By providing a collection of predefined shaped-portions, the shoemaker is able to select the most well-fitted shaped-portion to assemble a last which closely resembles the shape of the foot of an individual suffering from foot deformity. In this way, a cost efficient and easy-to-assemble last is provided. In addition, the shoemaker only needs to store one core arranged to receive at least one shaped-portion and at least one collection similarly, but differently, shaped aberrant shaped-portions.

In an alternative embodiment of the last of the present invention, the at least one shaped-portion may be manufactured based on at least a part of the contours of a foot of a person suffering from foot deformity. In this way the aberrant shaped-portion is designed on the basis of the specific foot of the individual. Although the costs for designing such specifically shaped aberrant shaped-portion will be higher compared to providing a collection of predefined shaped-portions, the shaped-portion provided and last assembled comprising the shaped-portion based on at least a part of the contours of a foot of a person suffering from foot deformity is still more cost efficient compared to the design of a complete custom-made last. In addition, storage space is reduced since only the specifically shaped aberrant shaped-portion needs to be stored, whereas only one core may be used for each specifically shaped aberrant shaped-portion.

In a further aspect, the present invention provides a shaped-portion for use in the last according to the present invention, wherein the shaped-portion defines an aberrant part of the inner dimensions of the shoe to be manufactured. The shape of the aberrant part of the shaped-portion at least partially corresponds to the aberrant part of the contours of a foot of a person suffering from foot deformity.

In an even further aspect, the present invention provides a core for use in the last according to the present invention, wherein the core is arranged for self-releasably and/or detachably receiving at least one shaped-portion according to the present invention, i.e. at least one aberrant shaped-portion wherein the aberrant part at least partially corresponds to the aberrant part of the contours of a foot of a person suffering from foot deformity.

The present invention further relates to a method for manufacturing an orthopaedic shoe, comprising the steps of: a) measuring the dimensions of a foot of a person suffering from foot deformity, b) assembling a last comprising at least one shaped-part and core according to present invention based on the dimensions measured in step a), c) manufacturing a shoe using the last of step b) and d) removing the last from the manufactured shoe, wherein in step d) the at least one shaped-portion and core are disconnected before removing the disconnected core and disconnected at least one shaped-portion.

In a preferred embodiment of the method of the present invention, the at least one shaped-portion is selected from a collection of shaped-potions, such that the selected shaped-portion closely resembles at least a part of the contours of a foot of a person suffering from foot deformity. In an alternative embodiment of the method of the present invention, the at least one shaped-portion is manufactured based on at least a part of the contours of a foot of a person suffering from foot deformity.

The present invention further relates to a kit for assembling a last according to present invention, comprising a core arranged for receiving at least one shaped-portion defining at least a part of the inner dimensions of the shoe to be manufactured and a first collection of differently shaped shaped-portions, wherein each shaped-portion self-releasably and/or detachably connectable to the core. Each shaped-portion provided by the kit of the present invention defines an aberrant part of the inner dimensions of the shoe to be manufactured. It is noted that the kit may further comprises a second collection of differently shaped shaped-portions connectable to the core, wherein each shaped-portion defines a non-aberrant part of the inner dimensions of the shoe to be manufactured. Indeed, in case the core of the present invention provides two or more receiving parts for receiving a shaped-portion, the second receiving part may be coupled with a shaped-portion defining a non-aberrant part of the inner dimensions of the shoe to be manufactured.

The present invention will be further elucidated on the basis of the non-limitative exemplary embodiments shown in the following figures. Herein: figure 1 shows a schematic side view of a conventional last for the manufacturing of a shoe; figures 2A and 2B show a perspective view of the core of the last of the present invention and two shaped-portions; and figure 3 shows a perspective view of the assembled last of the present invention.

Figure 1 shows a schematic side view of a conventional last 1 for the manufacturing of a shoe. The last 1 generally includes three main parts: a hinge 2 in the middle of the last 1 which allows the last to be divided for easy removal of the last 1 from the shoe, a back part 3 and a front part 4. The last 1 further defines the ball or ball girth 5, which is the greatest dimension around the forefoot area. The instep or instep girth 6 is the dimension around last 1 passing through the instep point. Furthermore, the waist or waist girth 7 is the smallest dimension around last 1 between the ball girth 5 and the instep girth 6. Further illustrated is the short heel or short heel girth 8, which is the dimension around last 1 passing through the instep and the heel feathering point 9. The last 1 of figure 1 further shows the toe thickness 10 which defines the space given for the toes of the individual wearing the shoe to be manufactured with last 1.

It is noted that by designing the last 1, the waist girth 7 restricts the design of the toe portion defined between the waist girth 7 and the tip of the toe portion 11. In case the toe portion comprises an aberrant shaped part, illustrated in figure 1 by protruding part 12, the front part 4 of last 1 cannot be removed from the shoe to be manufactured without deforming the toe portion of the shoe to be manufactured. Such deformation of the toe portion needs to be prevented in order to provide a shoe having sufficient firmness.

Furthermore, the last 1 shown in figure 1 comprises a contrefort 13 situated in the back part 3 of the last 1. In case a protruding part 14 is located in the contrefort 13 of last 1, the back part 3 can no longer be removed from the shoe to be manufactured, without deforming the contrefort 13 of the shoe to be manufactured. Again, it is noted that such deformation of the contrefort 13 needs to be prevented in order to provide a shoe having sufficient firmness.

Figures 2A and 2B show a perspective view of a core 50 comprising a front part 51 and back part 52 coupled together via a hinge 53. The core 50 has the same functionality as a conventional last 1 (see: figure 1), i.e. that both parts 51, 52 may be disconnected to enable the shoemaker to remove both parts 51, 52 from the shoe to be manufactured. Core 50 comprises two recessed areas 53, 54. The first recessed area 53, located in the front part 51 of the core 50, is arranged to receive a first module 60, which module 60 at least partially defines the inner dimensions of the toe portion of the shoe to be manufactured. The second recessed area 54, mainly located in the back part 52 of the core 50, is arranged to receive a second module 70, which module 70 at least partially defines the inner dimensions of the heel portion of the shoe to be manufactured. It is noted that the core 50 comprises a middle area 55 defining a part of the inner dimensions of the shoe to be manufactured. It is further noted that the sole part 56 (not shown) of the core 50 may define the inner dimensions of the sole of the shoe to be manufactured.

The module 60 as shown in figures 2A and 2B comprises a protruding part 61, which protruding part corresponds to an aberrant shaped part of a foot of an individual suffering from foot deformity. It is noted that in figures 2A and 2B the middle area 55 of the core 50 defines the waist girth 7 (see also: figure 1) of the last to be assembled.

By providing a module 60 comprising a protruding part 61 such that the maximum length of the girth of the module 60 exceeds the length of the waist girth, a shoe can be manufactured without the need of deforming the manufactured shoe once the front part 4 of a conventional last 1 comprising a protruding part 12 is removed from the shoe. In fact, the front part 4 of a conventional last 1 comprising a protruding part, which protruding part corresponds to the protruding part 61 as illustrated in figures 2A and 2B cannot be removed from the toe portion of a manufactured shoe at all, without drastically changing the design of the shoe to be manufactured. The module 60 as shown in figures 2A and 2B being self-releasably connectable to the core 50 provides a method for assembling a last for the manufacturing of an orthopaedic shoe without the need of significantly changing the design of the shoe to be manufactured to provide a suitable fit. By providing a core 50 and a module 60, the shoemaker is enabled to assemble a last which last at least closely resembles the shape of a foot of an individual suffering from foot deformity.

It is further noted that module 70 corresponds to a normal formed heel portion not comprising any protruding and/or aberrantly shaped parts. It is further noted that a part of the second recessed area 54 of core 50 also covers a part of the front part 51 of the core 50. Therefore, module 70 not only defines the heel portion of the shoe to be manufactured but also a part of the instep of the shoe to be manufactured.

Figure 3 shows a perspective view of a last 80 according to the present invention, wherein the core 50 and modules 60, 70 are connected together to form a last 80 for the manufacturing of an orthopaedic shoe. Last 80 comprises protruding part 61. Module 60 is self-releasably connected to the recessed area 53 (not shown) of core 50 such that the module 60 is retained in the shoe to be manufactured once the front part 51 is removed from the manufactured shoe. Module 70 is detachably connected to the recessed area 54 (not shown) of core 50 such that the shoemaker is able to remove the module 70 before removing the back part 52 of core 50 from the shoe to be manufactured. Since module 70 is a normally formed heel portion of last 80, the module 70 can be directly removed from the manufactured shoe without any further displacement of the module 70. However, in case the module 70 comprises a protruding part located in the heel portion of the shoe to be manufactured, e.g. the contrefort of the shoe, module 70 may be first moved in the direction of the front portion of the manufactured shoe before removal of the module 70 from the shoe. By moving the module 70 in a longitudinal direction of the shoe, the module 70 is displaced between the inner surface of the manufactured shoe and the outer surface of middle area 55 of the core 50 and, optionally, depending on the dimensions of the protruding part of module 70, a part of the outer surface of module 60. Since module 70 should be able to be moved into a longitudinal direction of the shoe, some space should be available between the inner surface of module 70 and the outer surface of the recessed area 54 of core 50. The available space needed depends on the dimensions of the aberrant shape of module 70 to allow the shoemaker to translocate module 70 to enable removal of module 70 from the manufactured shoe.
