The Schaffner Patent is a design patent which discloses the concept of having strap members along the back with a flexible band member at the end of the side strap.
The Lahnstein Patent discloses the broad concept of having a shoe wherein the length and width of the shoe may be adjusted as a child's foot grows so that the shoe at no time will bind or otherwise be uncomfortable for the child. The width of the shoe can be adjusted by having mating members 14 and 13 on one side of the shoe fixed respectively to different locations on mating members 16 or 17 so that the tightness of the shoe can be contracted for a smaller foot and expanded for a larger foot. Also, the front of the shoe 12 can be mated with member 14. The length of the shoe can also be adjusted by having mating member 12 where the length can be adjusted.
The '241 Rigsby Patent embodies within it the concept of having a baby shoe that is adapted to be enlarged to compensate for the growth of an infant's foot. The shoe essentially consists of a front section 46 with a multiplicity of different eyelets so that as the shoe lace is expanded through the eyelets, the length of the shoe can either be increased or decreased depending upon which series of eyelets are engaged with the shoelace.
In the '086 Rigsby Patent the length is adjusted by having different eyelets so that a shoelace can be threaded through different eyelets to increase or decrease the length of the shoe.
The Waters Patent embodies the concept of having an adjustable child's shoe so that the size of the shoe can be increased as the child grows. The adjustment is made on the rear by having an interlocking weaving pattern of a shoelace with a pleated member as best shown in
The Cary Patent is for adjustable footwear and is intended as an adult orthopedic shoe wherein the shoe has a toe covering which includes sections that are laterally adjustable and easily fixed in any given position of adjustment. The toe covering is split along a midline of the shoe to form two lateral sections that can be adjusted towards and away from the shoe midline and tongue like element is secured to the forward portion of the shoe to overlap the two lateral covering sections and to maintain the sections in the desired adjusted position. Therefore, infinite adjustment is available through the use of the mating Velcro sections. The idea however is to adjust the front width of the shoe to accommodate a specific width of a person so that the shoe can be wider or narrower with the Velcro members 34 being spaced further apart or closer together and then joined by the mating Velcro member 36.
The Simister Patent is a baby expansion slipper wherein the length of the shoe can be adjusted by having a mating snap member 6′ either go to snap member 6d or 6b′ and the length is thereby adjusted depending upon which snap member-is engaged.
The Munschy Patent discloses a disposable shoe where there are various fold lines as best illustrated in
The Clarvit Patent is a design patent application for a baby shoe. Essentially the width of the shoe can be adjusted by having mating Velcro™ fasteners as three members as indicated in the figures so that the overall width of the front of the shoe can be adjusted depending upon how tightly the Velcro™ strap members are engaged.
The Rousseau Patent has a detailed disclosure of how to adjust the sides of a shoe. Specifically, the invention discloses the concept of having an adjustable shoe where the rear width of the shoe and the length and width of the shoe can be adjusted by various mating Velcro members on different portions of the shoe.
The '523 Lin Patent discloses an adjustable child's shoe which discloses a plurality of different fastening members on the toe and the heel to adjust the length of the shoe.
The '980 Lin Patent is an adjustable shoe which contains additional features such as having the rear adjusted as best illustrated in
The Darby Patent is a design patent which protects the shape of the product. This patent is for a surgical shoe wherein there is a flap on the top of the shoe that adjusts the overall width of the front portion of the shoe and a band and strap that adjusts how tight the top of the shoe is over the person's upper foot area.
The Ou Patent discloses an adjustable and disposable foot care article with an adjustable rear fastening member as best show in
The Lewis Patent is an adjustable sizable protective boot. The overall length of the shoe can be adjusted by the front flap 18 and its mating Velcro member being affixed along any location along the mating Velcro™ members 30 along the front portion of the shoe. In addition, there is a band so that the overall width of the shoe at the location around the base of the foot as well as the upper portion of the foot can be adjusted in terms of width.
The Miller Patent discloses a method of making an expandable shoe which involves: “A method of making an expandable shoe is disclosed. An intermediate footwear structure is provided having an expandable upper portion. A stabilizing material is provided to the intermediate structure to resist expansion of the upper portion, and a last is inserted into the intermediate structure. A subsequent manufacturing operation is performed to the intermediate structure, and the stabilizing material is acted upon to permit longitudinal movement of the upper portion. The size of the last is selected from among the sizes within the intended range of shoe sizes for the expandable shoe, depending on the characteristics of the upper portion of the shoe, and the desired shoe size range.”
The European Patent Application which was published in 2006 discloses: “A shoe 10 which comprises a sole 11 and an upper positioned above the sole and having a height so as to cover up to an ankle. The upper comprises a lower upper 12 including a tongue for covering an instep, right and left side parts 14a, 14b having a height so as to cover an anklebone and gradually reduced in height backward, and a rear part 17 which connects the right and left side of parts 14a, 14b, and a higher upper 20 having a height so as to cover the ankle from a position in which an upper region of the lower upper is overlapped, one end connected to the right side part 14a of the lower upper 12, a middle region partially and sequentially overlapping with the right side part 14a, the rear part 17 and the left side part 14b of the lower upper 12, and a fixing part 27 connected to the left side part 14b and detachably connected to a hook and loop fastener 34 of the higher upper 20.”
The present invention relates to expandable and adjustable baby shoes or booties which can be customized during a baby's first two (2) years. The concept allows the shoe the ability to be expanded as the baby's foot grows so that a single shoe can be used for a baby up to 24 months of age. Also, since the ankles of boys' and girls' feet are different, there is an ankle variation expansion member in the back as will be discussed that enables the width of the back of the shoe to be adjusted.
In an initial concept of the invention as discussed in the provisional patent application, and improved upon as set forth in this full patent application. The invention works by simply pulling on an elastic strap connected to a fastener member which can be attached to the shoe by infinitely variable and hook and loop attachment mechanism so that the length of the shoe can be reduced and expanded. A separate ankle adjustment mechanism with an infinitely variable attachment mechanism enables the shoe to accommodate variations in ankle sizes for boys and girls and to accommodate ankle growth as the infant grows.
It is an object of the present invention to provide an infant shoe including, but not limited to, unisex designs which can be used by infant boys and infant girls, with adjustment mechanisms which can vary the length of the shoe and vary the interior size of the shoe at the ankle area. The present invention is an improvement over prior art variable infant shoes in that the length is quickly adjusted to any desired length within a given range by mating hook and loop fasteners which can be connected at a multiplicity of connection locations to precisely achieve a desired length. The ankle area of the shoe can also be quickly adjusted to any desired size within a given range by mating hook and loop fasteners which can be connected at a multiplicity of connection locations to precisely achieve a desired ankle size for the shoe. The mechanism is also protected so that it will not come loose while the infant is active.
It is a further object of the present invention to provide an expandable and adjustable baby shoe for infants from 0 months up to 24 months of age with each of the shoes in the pair of shoes having adjustment mechanisms to accommodate growth of the foot and to accommodate differences in the size of the foot in an infant.
It is also an object of the present invention to provide an infant shoe made of flexible but strong material such as leather, suede and other strong flexible material which can be compressed and expanded and endure wear and tear.
The shoe can expand from its full length of approximately 5 inches and retract to its smaller length of approximately 3.25 to 4 inches. The method by which this unique concept works is by adding in a total of 1 to 1½ extra inches of fabric where when the shoe is at its smallest size, the fabric is “squeezed” throughout the top of the foot. In brief, the largest size shoe is designed to fit a 24-month-old child, and an adjustment of the extra fabric is made from the top so that it “shrinks”, thus converting the size back to its infant size. The principle discussed here for a baby shoe can also be incorporated into a slipper worn by both children and adults.
Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.
Referring particularly to the drawings for the purpose of illustration only and not limitation, there is illustrated:
Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.
The basic concept of the invention as disclosed in the provisional patent application and in
Referring to
Sewn into the interior of the front 18 of the baby shoe 10 at a location adjacent the toe area 16 is a flexible elastic strap member 40 which extends within the interior of the body 12 between the interior layer 24 and the outer surface layer 22 of the top section 14 and is visible from the openings 26, 28 and 30. The flexible elastic strap member 40 extends out of an opening 32 between the interior layer 24 and outer surface layer 22 located adjacent the interior rim 34 of the top section 14. The flexible elastic strap member 40 terminates in a mating fastening member 42 having an upper surface 44 and lower surface 46 which includes a surface of mating fastening members 48 such as a hook or loop fastener. On the outer surface layer 22 of the top section 14 of the baby shoe 10 at a location adjacent the opening 32 is mating fastener member 50 such as a hook or loop fastener. The fasteners 48 and 50 are mating fasteners so if one of the fasteners is a hook fastener, then the other fastener is a mating loop fastener.
One key innovation of the present invention is the combination of the flexile elastic strap member 40 which extends through the interior of the bootie or baby shoe 10 between the interior layer 24 and the outer surface layer 22 which is visible through the openings or slits 26, 28 and 30. The top 14, sole 60 and sidewalls 62 and 64 of the body 12 are made of soft flexible material and the openings 26, 28 and 30 further enable the top 14, sole 60 and sidewalls 62 and 64 to be compressed as the flexible elastic strap 40 is pulled so that the mating fasteners 48 and 50 can be joined at any multiplicity of locations to decrease the length of the front of the baby shoe 10 or increase the length if the baby shoe 10 is in its most compressed configuration. The top 14, sole 60 and sidewalls 62 and 64 form a first interior space 10A which is also reduced as the shoe 10 is compressed. Although it is within the spirit and scope of the present invention to have an outer surface layer 22 without openings 26, 28 and 30, the openings facilitate the compression of the baby shoe 10 to its smallest and smaller lengths.
The baby shoe 10 is illustrated in its uncompressed length “L1” in
When the infant is at its earliest age when the baby shoe 10 is worn, the baby shoe is in its most compressed condition as illustrated in
A second key innovative feature of the present invention is the ability to adjust the tightness of the bootie around the infant's ankle area and also over the infant's foot. The top section 14 of the baby shoe/bootie 10 is affixed to a bottom sole section 60. The baby shoe 10 also comprises a pair of oppositely disposed sidewalls 62 and 64 which are affixed to the bottom sole section 60 and extend rearwardly to create a back section wall 66 of the baby shoe 10. The back section wall 66 and a portion of the sidewalls 62 and 64 surround the back and sides of an ankle of an infant when the baby shoe 10 is worn and the top section 14, sidewalls 62 and 64 and sole 60 enclose the infant's foot.
The top section 14 includes a pair of oppositely disposed elongated extension flaps 70 and 76. Extension flap 70 includes an interior surface 72 having a mating fastener 74 which is preferably one of a hook or loop mating fastener. Extension flap 76 includes an interior surface 78 having a mating fastener 80 which is preferably one of a hook or loop mating fastener. The back section 66 includes an exterior sidewall 82 having a mating fastener 84 which preferably is either a hook or a loop fastener. The mating fasteners 74 and 80 are the same and mate with the mating fastener 84. Therefore, if mating fasteners 74 and 80 are hook fasteners, then mating fastener 84 will be a loop fastener. Conversely, if mating fasteners 74 and 80 are loop fasteners, then mating fastener 84 will be a hook fastener. As illustrated in
An additional innovation of the present invention is a covering flap 90 attached to the back area wall 66 and sidewalls 62 and 64. The covering flap 90 is preferably attached along a top surface 62A and 64A of the sidewalls 62 and 64 and along the top surface 66A of the back wall 66. The covering flap is illustrated in an open condition in
The extension flaps 70 and 76 as illustrated in
The invention solves the following problems:
The ability and flexibility to make necessary adjustments in length and width with ease providing appropriate comfort and support for growing feet.
Eliminating the need to replace shoes every few months within the first two years during the time feet grow the most.
Giving a customized fit for all types of feet (wide and narrow) with ease by putting on and removing shoes,
Saving time and money on shopping for replacement baby shoes.
Convenience in making proper adjustments when one foot is larger than the other.
This invention is different from any existing and/or patented expandable and adjustable shoe. The only other company to manufacture an expandable shoe is called Inchworm. It offers expandable tennis shoes designed for children 4 years old through adults, and not designed for infants or toddlers. Inchworm shoes grow in half size increments by pushing a button on the side, and pulling the toe of the shoe to adjust into the next size. The materials used to manufacture tennis shoes are typically hard and sturdy material suitable to withstand wear and tear.
The present invention does not have any mechanical buttons, but simply an elastic strap member 40 by which the front length of the baby shoe 10 can be adjusted as discussed above. By way of example, the shoe can expand from a compressed length of approximately 3.25 to 4 inches to a fully expanded length of approximately 5 inches. Through this innovation, the length of the baby shoe 10 can be expanded as the foot of the infant grows.
With the present invention, there is no longer a need to leave a gap too large or too tight between the toes and no more need to constantly replace the shoe or bootie for a comfortable and protective fit. The present invention expandable and adjustable shoe will be available in a variety of fabrics such as soft leather/suede and other soft fabrics, and will be available in an ever-increasing color selection.
It has been documented that during babies' first years, soft sole shoes are the next best thing to bare feet, allowing babies to naturally develop toe and muscular strength. Since walking in bare feet is not always practical, these shoes will consist of the finest materials such as leather, suede and soft fabric resulting in a soft, breathable and washable, as well as attractive shoe that protects the baby's tender feet without compromising freedom of movement and growth. To date, most baby shoes are sized in such a way that they need to be replaced every few months. For example, current baby shoe sizes come in 0-3 months, 3-6 months, 6-9 months, 9-12 months, 12-18 months and 18-24 months. Baby shoes such as the popular Robeez™ brand are made out of leather and are sized 0-6 months, 6-12 months, 12-18 months and 18-24 months respectively.
In prior art embodiments, elastic used around the ankle cannot accommodate babies with “chubby” feet. The elastic band is too tight and causes poor circulation for those wider feet. On the other hand, babies with narrow feet have the problem of their shoes slipping off their feet. Another key innovation of the present invention is having the adjustment straps 70 and 76 and infinitely variable attachment means 74, 80 and 84 so that the attachment of the baby shoe 10 around the ankle is just right to accommodate the specific needs of the infant.
The covering flap 90 provides additional comfort and security. The shoe 10 is made for both the left foot and the right foot. In this way, if one foot is slightly larger or smaller than the other, the specific size for that foot can be accommodated through the adjustment mechanisms of the present invention and it is not necessary to buy two separate pairs of shoes of different sizes to accommodate the variation in the infant's feet. Once a shoe is worn, it conforms to the shape of the left to right foot so a label/tag will be placed on the right side of the shoe to identify the right foot. This identifies which shoe is to be worn on the right foot.
The shoe may be constructed of three pieces (top 14, side walls and back wall 62, 64 and 66, and sole 60) of flexible and solid material such as soft breathable leather, suede and fabric that will stretch from the top center of the shoe and be compressed until the desired length is achieved. The thin non-skid sole 60 of the expandable shoes allows the child to feel the ground both indoor and outdoor, allowing a secure grip and promoting natural muscle development for a healthy foot development as well as keeping little feet dry in summer and warm in winter.
While the present invention focuses on an expandable and adjustable baby shoe, the principles of the present invention can also be incorporated into a slipper worn by children over 24 months of age. It will be appreciated that the term “children's slipper” can be substituted for the term “baby shoe” so that all of the unique features of the present invention are also incorporated into an expandable and adjustable children's slipper.
Of course the present invention is not intended to be restricted to any particular form or arrangement, or any specific embodiment, or any specific use, disclosed herein, since the same may be modified in various particulars or relations without departing from the spirit or scope of the claimed invention hereinabove shown and described of which the apparatus or method shown is intended only for illustration and disclosure of an operative embodiment and not to show all of the various forms or modifications in which this invention might be embodied or operated.
This application is a continuation of U.S. patent application Ser. No. 12/459,746, filed Jul. 7, 2009, which claims the benefit of U.S. Provisional Application No. 61/135,585, filed Jul. 21, 2008. The entire contents of both of these applications are fully incorporated herein by reference for all purposes.
