Patent Application
20210022435
The present invention relates to footwear, and more particularly to infant footwear including a convertible heel panel that facilitates donning and removal of the footwear.
The shoes of infants, such as babies, toddlers, adolescents and the like, come in a variety of configurations. Many infant shoes are configured specifically to accommodate the mobility of the infant. With older infants, footwear can be constructed to be well secured to the foot, thereby preventing the footwear from coming off, given the high mobility and activity of those children. In the case of very young infants, who are not prone to being too mobile, and even less prone to walking, shoes can be constructed more for the convenience of the parent of the infant.
For example, some infant shoes are constructed to resemble a sock with a thin, flexible outsole. The sock extends upward from the outsole, and includes a flexible and/or stretchable ankle collar. A parent can expand the collar, much like a sock, and insert the infant foot into the collar and the remainder of the sock. While this construction works for many infant feet, pudgier feet are more difficult to place through the collar and into such shoes. Where the infant already is wearing a conventional sock, the process can be complicated.
Other infant shoes can be configured to resemble a sandal with an open back so that the infant foot easily slips into the shoe. While easy to install on an infant foot, these types of footwear can be prone to sliding off the foot, particularly where the child is active and crawling.
Accordingly, there remains room for improvement in the construction of an infant footwear that is easy to don and remove relative to a foot, and yet is comfortable to the infant.
A footwear construction for an infant includes an upper having a first panel that transitions to a heel closure flap and a second panel that transitions to a minor upstanding wall extending around a heel of the footwear. The heel closure flap is operable in an closed mode, in which it overlaps the minor upstanding wall such that no vertical gap is formed therebetween in the heel region and secures the footwear on an infant foot, and in an open mode, in which the flap is distal from the second panel and the minor upstanding wall to expose a heel opening so that the infant foot can be placed in a void of the footwear, passing at least partially through the heel opening in the open mode.
In one embodiment, the upper includes an extension of the medial panel around the heel region of the footwear, ending at or on the lateral panel. The extension, in the form of a heel closure flap, covers a heel opening configured for easy foot entry. The heel closure flap can be secured over the heel opening and generally to the lateral panel to secure the footwear on an infant foot.
In another embodiment, the heel closure flap can include a first end portion joined with the medial panel and extending rearward along the medial side, a heel portion configured to extend rearward about the heel of an infant, and a second end portion extending from the heel portion forward along the lateral side adjacent the heel region. The second end portion can include a first closure element. A fin on the lateral panel can include a second closure element. The first and second closure elements can be removably joined with one another so the heel closure flap can be converted from the closed mode to the open mode manually, by disassociating the closure elements.
In still another embodiment the first and second closure elements can each be complimentary hook and loop closure elements, secured respectively to the fin on an exterior of the lateral panel, and along an interior surface of the end portion of the heel closure flap.
In yet another embodiment, the upper is joined with an outsole having a rearwardmost portion at which a vertical plane is defined. The heel portion of the closure flap can be angled forward from the vertical plane, so that the heel portion engages the infant's heel above the calcaneus bone and secures the footwear on the foot.
In even another embodiment, the heel closure flap includes an interior closure surface and an opposing exterior closure surface. The minor upstanding wall includes an interior wall surface and an opposing exterior wall surface. In the closed mode, the interior closure surface directly engages the exterior wall surface.
In still yet another embodiment, the minor upstanding wall includes an upper wall edge. The heel closure flap includes a lower closure edge. The lower closure edge is below the upper wall edge when the closure is in the closed mode.
In a further embodiment, the minor upstanding wall includes a lower edge. The outsole can include a foxing band extending around a sidewall of the outsole. The lower edge can be concealed by a foxing band to provide a neat, clean appearance.
In still a further embodiment, the lower closure edge can be between the upper wall edge and the foxing band when the closure is in the closed mode. Optionally, the minor upstanding wall can include a height. The height of the minor upstanding wall can be between 2 mm and 20 mm inclusive.
In yet a further embodiment, a method is provided. The method can include: providing the upper with the medial panel and heel closure flap, and the lateral quarter including a fin; converting the heel closure flap from a closed mode, in which a first closure element joined with the heel closure flap is removably secured to a second closure element joined with the fin, with the heel closure flap overlapping a minor upstanding wall, to an open mode, in which the first closure element is detached from the second closure element and the heel closure flap is distal from the fin and the minor upstanding wall to expose a heel opening in the heel region; and passing the foot at least partially through the heel opening while the heel closure flap is in the open mode to place a foot of an infant in a void of the upper.
In even a further embodiment, the method can include returning the heel closure flap to the closed mode so that the first closure element is removably secured to the second closure element, with the heel opening closed by the heel closure flap which is placed adjacent the minor upstanding wall to limit the engagement of the closure against a heel of the infant and yet snugly secure the footwear to the foot of the infant.
The present infant footwear construction provides benefits in use, installation and removal that previously have not been achievable. With the easy to use heel closure flap, a caregiver can quickly don and remove footwear from an infant despite the infant's activity or movement. The closure can be well secured to the user's foot to avoid losing the footwear in certain environments. Likewise, the flap can be removed to expose a large opening through which a variety of feet shapes and sizes can be rapidly installed. The minor upstanding wall can assist in properly installing the infant foot in the footwear, to set it at the proper depth in the footwear. It also can temporarily hold the footwear on the foot until the closure flap is fully closed to secure the foot in the footwear.

The footwear 10 can include a side-to-side width W, a heel-to-toe longitudinal length L and a longitudinal axis LA, which can be shared with the various elements of the footwear, such as the upper and the outsole.
The footwear 10 can include a textile upper 30 or upper assembly joined with the outsole 50. The upper 30 can be formed from a variety of material elements joined together to cover at least a portion of the wearer's foot. The material elements can be selected based on the intended uses of the article of footwear 10, and can include synthetic textiles, mesh textiles, polymers or leather, for example. The upper 30 can be constructed to improve the rigidity of the sole assembly 20. For example, the upper can be constructed from leather, plastic, canvas or other materials. The upper 30 can include one or more closure elements. The upper 30 additionally includes the foot opening 26 for receiving the wearer's foot and a lower periphery for attachment to the outsole 50. The upper 30 may also include various trim, cushioning, and reinforcing elements. For example, the upper 30 may include a toe cap to reinforce the vamp 58. Embroidery and other trim or extra material may be added to the upper 30 as desired for functional or aesthetic reasons. Further, reinforcing elements may be affixed to the upper 30 to reinforce the portions of the upper 30. The interior of the upper 30, such as a vamp and panels may be covered by a lining material, such as a layer of DriLex, Cambrelle or other lining materials. The lining material may be a single layer of material or it may be a laminated combination of a plurality of materials. For example, the lining material may include integrated padding throughout or in select regions, such as around the ankle and the foot opening 26. The construction of the illustrated upper 30 is merely exemplary, and the present invention may be incorporated into footwear that includes essentially any upper construction.
A footbed (not shown) can be positioned within the foot void 24 defined by the upper 30 and can be non-stretchable and lightweight and joined to the upper 30 to provide a void for receipt of the wearer's foot. The footbed can be constructed from a sheet of material, such as foam, EVA, PU, latex, gel or other materials, and by virtue of its compressibility, provide cushioning, and may also conform to the foot in order to provide comfort, support, and stability. The lower peripheral allowance or edge of the upper can be stitched, cemented, or otherwise fastened to the footbed around the perimeter of the footbed. The sole assembly 20 can be combined with any other type or style of upper construction capable of being suitably joined with it, for example, a Strobel construction. The joining of the sole assembly/outsole and the upper can be accomplished using adhesives, cement, injection molding, pour molding or any other technique used to join an upper and sole assembly.
With reference to
The upper 30 can include a contoured vamp 58 configured to extend over metatarsals in the forefoot region 12 of the upper 30 and forms the void 24 thereunder between the vamp 58 and the outsole 50. The contoured vamp 58 may be manufactured from any combination of pieces of upper material. The various pieces of the upper 30 may be manufactured from any of a wide range of materials, such as leather, synthetic leather, mesh, canvas, textile (e.g. woven, knit, bonded), fabric and molded components.
The upper 30 includes medial and lateral panels 60 and 80 in spaced relationship and disposed on opposite sides of the footwear 10 and the wearer's foot. The medial panel 60 can extend rearward from the vamp 58 on the medial side of the longitudinal axis LA of the footwear 10. The medial panel 60 is positioned above the sidewall 56 of the outsole 50. The medial panel 60 transitions to a heel closure flap 62. These two components can be integrally formed as a single piece or element, or can be separate elements stitched, sewn or otherwise joined with one another. In some cases, the heel closure flap 62 can be an extension of the medial quarter panel 60, having a free end or portion as described below. The heel closure flap 62 can extend from a medial side of the footwear 10, rearward around a heel, to a lateral side of the footwear 10. The heel closure flap 62 can be a continuous piece, including first and second end portions 64, 66 and a heel portion 68 therebetween. The first end portion 64 can be joined with the medial panel 60 and extends rearward, along the medial side, and into the heel region 16 of the footwear 10. The first end portion 64 can transition to the heel portion 68. The heel portion 68 can form the arcuate portion of the heel closure flap 62 and is configured to extend rearward, about and behind a heel of an infant. The heel portion 68 can transition to the second end portion 66. The second end portion 66 can extend from the heel portion 68 forward, along the lateral side of the footwear 10 and adjacent the heel region 16. The heel portion 68 of the heel closure flap 62 is configured to be angled forward, at angle Al denoted in
Referring to
The second end portion 66 of the heel closure flap 62 can be releasably securable to the lateral panel 80 via one or more corresponding releasable fasteners, such as hook and loop closure elements (for example, Velcro® fasteners), a buckle, snaps, magnets, a friction device, or any other suitable device capable of temporarily fastening one footwear component to another. A first hook and loop closure element 72 can be located on the second end portion 66 the heel closure flap 62. The lateral panel 80 can include a corresponding second hook and loop closure element 74 configured to engage the first hook and loop closure element 72.
The lateral panel 80 can transition to a minor upstanding wall 84 as shown in
The heel closure flap 62 defines a lower closure edge 100, an upper closure edge 101, and opposing interior and exterior closure surfaces 102, 104. The upper closure edge 101 is farther forward by a distance D2 (
Optionally, the fin 82 includes an upper fin edge 108 that transitions to a downward sloping edge 110 in the heel region 16, on the lateral side of the footwear 10. The downward sloping edge 110 can transition to and can be continuous with the upper wall edge 86 of the minor upstanding wall 84. Further optionally, the minor upstanding wall 84 transitions to the upward sloping edge 110, which forms the upper fin edge 108, and the upward sloping edge 110 can be continuous with the upper wall edge 86. The second end portion 66 of the heel closure flap 62 can have a similar shape, contour, and slope as that of the fin 82 so that the components, when adjacent one another, are in alignment to provide a nice aesthetic appearance.
In use, the heel closure flap 62 can be operable between a closed mode and an open mode. In the closed mode, illustrated in at least
As shown in
When the heel closure flap 62 is in the open mode, the first hook and loop closure element 72 on the second end portion 66 the heel closure flap 62 can be detached from the second hook and loop closure element 74 on the lateral panel 80. In the open mode, illustrated in at least
A method 200 of using the infant footwear construction 10 is presented in greater detail in connection with the flow chart of
Providing an upper 30 joined with an outsole 50 is step 202. The upper 30 includes the medial panel 60, which extends on the medial side of the longitudinal axis LA of the footwear 10. The medial panel 60 transitions to the heel closure flap 62. The lateral panel 80 extends on the lateral side of the longitudinal axis LA. The lateral panel 80 includes the fin 82 which transitions downward to the minor upstanding wall 84.
Converting the heel closure flap 62 from a closed mode to an open mode is step 204. In the closed mode, the first closure element 72 is joined with the heel closure flap 62 and is removably secured to the second closure element 74 joined with the fin 82. The heel closure flap 62 overlaps the minor upstanding wall 84 such that no vertical gap is formed therebetween in the heel region 16. In the open mode, the first closure element 72 is detached from the second closure element 74 and the heel closure flap 62 is moved to be distal from the fin 82 and the minor upstanding wall 84 to expose the heel opening 112 in the heel region 16.
Passing the foot at least partially through the heel opening is step 206. An infant's foot can be placed into the void 24 of the upper 30 when the heel closure flap 62 is in the open mode.
Returning the heel closure flap 62 to the closed mode is step 208. In the closed mode, the first closure element 72 is removably secured to the second closure element 74 and the heel opening 112 is closed by the heel closure flap 62. The heel closure flap 62 is placed adjacent the minor upstanding wall 84 to limit the engagement of the heel closure flap 62 against a heel of the infant and yet snugly secure the footwear 10 to the foot of the infant.
The present infant footwear construction provides benefits in use, installation, and removal. With the easy to use heel closure flap 62, a caregiver can quickly don and remove the footwear 10 from an infant despite the infant's activity. The heel closure flap 62 can be well secured to the user's foot to avoid losing the footwear in certain environments Likewise, the heel closure flap 62 can be removed to expose the large heel opening 112 through which a variety of feet shapes and sizes can be easily installed. The minor upstanding wall 84 assists in properly installing the infant foot in the footwear 10 and to set the foot at the proper depth within the footwear. The minor upstanding wall 84 also can temporarily hold the footwear 10 on the foot until the heel closure flap 62 is fully closed to secure the foot in the footwear 10.
