Description
Collapsible Shoe
Field of the Invention
The present invention relates to shoes, and in particular, to collapsible shoes.
Description of the Prior Art
Conventionally shoes are made to a given fixed size and do not generally have the facility to be conveniently temporarily reduced in size for ease of storage - in a ladies handbag or an item of clothing, for example
Various attempts have been made over time to address this problem, but these generally suffer from limitations of type of material usable, the need for holding mechanisms to hold the shoe in their collapsed position, or having the shoe collapse in a way that leaves the sole exposed, potentially soiling the storage object (ladies handbag or clothing, for example, as mentioned above).
One particular problem is that in one form of known but not commonly known shoe such as shown in WO2008/093035 there is disclosed a foldable shoe having a sole comprising a forward sole portion extending from a front toe part of the shoe to an in-step part, a rear sole portion ex tending from a rear most part of the shoe to said in-step, said forward sole portion and said rearward sole portion co-operating to form a substantially continuous sole when the shoe is worn by a user; and said forward sole port ion and said rearward sole portion being separable from each other when the sole is in a folded condition However such a shoe requires that the sole is split in order to provide a means of bending a shoe to a smaller size. It is not possible to have any other form as the continuous sides of the uppers only allows for folding of the shoe in this way
The breaking of a sole is detrimental tyo shoe construction in that it therefore renders the shoe not weather resistant and the cut in the sole can accumulate any amount of ground dirt at each step Apart from creating extremely uncomfortable shoes it also renders the shoe likely to quick deterioration.
As used in this specification, the term 'sole' of a shoe is intended to mean the sole only or the sole and heel combined where the sole and heel are connected
As used in this specification, the 'platform' of the shoe is the surface where the foot is actually placed inside the shoe It also has an underside which for the purpose of this specification will be called the 'platform street layer'
As used in this specification, the 'upper' of the shoe is the upper portion of the shoe which covers the foot and may include a heel protector and may include straps or other mechanism to secure the shoe to the foot
It is an object of the present invention to overcome or at least substantially ameliorate one or more of the problems associated with the pπor art
Summary of the Invention
The present invention provides a collapsible shoe including a shoe platform that includes a shoe sole having an underneath continuous platform street layer and an upper collapsing mechanism, forming at least two parts, a shoe upper having at least two parts with one part connected to a respective one of the two parts of the shoe platform, and a connection means extending between the two parts of shoe upper, wherein the collapsing mechanism allows the collapsible shoe to fold back on itself such that the continuous platform street layer of the at least two parts substantially face each other
In one form of the invention there is provided A collapsible shoe including a shoe platform that includes a shoe sole having an underneath continuous platform street layer and an upper collapsing mechanism, forming at least two parts, a shoe upper having at least two parts with one part connected to a respective one of the two parts of the shoe platform and a connection means extending between the two parts of shoe upper, wherein the collapsing mechanism allows the collapsible shoe to fold back on itself such that the continuous platform street layer of the at least two parts substantially face each other
The platform of the shoe can be made of a single layer of material which incorporates the sole or can be made from a plurality of laminations, which may incorporate the sole Alternatively, the sole can be added to the underside of the platform as a separate entity to the platform
The platform can be of various materials, but must be flexible enough to fold readily when being collapsed and must readily resume its full size when being returned to its original length Such a shoe would be convenient if the wearer needs to change venue, from the
beach, perhaps, where casual sandals are acceptable, to a more formal setting, where dress shoes would be more appropriate, and can be conveniently and discreetly stored in its collapsed state in a handbag or an item of clothing
The invention also provides in another form a method of forming a collapsible shoe including the steps of a providing a platform of a shoe including a continuous sole with an upper collapsing mechanism to allow folding of at least two parts , b attaching an upper to the platform including two separate parts joined to respective ones of the at least two parts and to each other by a connection means, wherein the collapsing mechanism allows the collapsible shoe to fold back on itself such that the continuous platform street layer of the at least two parts substantially face each other
The collapsing mechanism can be provided by an incision across the width of the platform of the shoe approximately half way along the length of the shoe This depth of the incision should be sufficient to penetrate only to a level where the platform street layer is not penetrated but sufficient to make the shoe easy to collapse The street layer which will act as a hinge mechanism will thus be easy to operate The hinge mechanism will act such that the sole will collapse on each other, leaving the shoe upper to the outside of the collapsed shoe
The shoe upper can be of various materials, including fabric, lace, leather or a variety of other materials, which can be sewn, glued, or otherwise secured to the shoe platform Also, if the shoe incorporates a mechanism for securing the shoe to the foot, this mechanism can be of various kinds, including straps, laces, buckles, Velcro, or other suitable mechanisms, or a wide variety of alternative mateπals
The shoe will also have a locking mechanism to keep the shoe in the collapsed state when required
