FOOTWEAR HAVING SELECTIVELY ATTACHABLE SOCKLINER
Footwear includes a sole, an upper attached to the sole to define a volume for receiving a foot therein, and a sockliner received in the volume and overlying the sole. The sole includes at least one first fastener element formed therein, and the sockliner includes at least one second fastener element formed therein. The second fastener element is adapted for snap-together fastening with the first fastener element for securing the sockliner to the sole.
The present invention generally relates to footwear and more particularly, to footwear having a selectively attachable sockliner.
BACKGROUND OF THE INVENTIONConventional footwear includes an upper, a sole underlying and attached to the upper, and a sockliner overlying the sole. The sockliner is the portion of the footwear upon which a wearer places their foot. Often, the sockliner is glued and/or stitched to the sole. However, the gluing and/or stitching process is typically conducted at a manufacturing facility different than the one at which the sole and sockliner were produced. As a result, production delays and added costs are incurred in handling, packing, and shipping the sole and sockliner from one manufacturing facility to another.
Moreover, permanently attached sockliners, such as by gluing and/or stitching, prohibit the sockliner from being removed from the footwear for cleaning or replacement. It is also known to place the sockliner on the sole without any type of connection. However, the sockliner can bunch or gather within the footwear thereby causing discomfort to the wearer.
SUMMARY OF THE INVENTIONIn one aspect, the present invention is directed to footwear generally comprising a sole, an upper attached to the sole to define a volume for receiving a foot therein, and a sockliner received in the volume and overlying the sole. The sole includes at least one first fastener element formed therein, and the sockliner includes at least one second fastener element formed therein. The second fastener element is adapted for snap-together fastening with the first fastener element for securing the sockliner to the sole.
In another aspect, the present invention is directed to footwear generally comprising an upper shaped to define a volume for receiving a foot therein and having an opening for passage of the foot into the volume. The upper is attached to a sole having a top surface and a bottom surface. The top surface includes a plurality of cavities and openings allowing access to the cavities. A sockliner is for overlying the top surface of the sole and underlying the foot of the wearer. The sockliner includes a plurality of tabs selectively insertable into the cavities of the sole to thereby secure the sockliner to the sole.
Other objects and features will be in part apparent and in part pointed out hereinafter.

DESCRIPTION OF THE PREFERRED EMBODIMENTSReferring now to the drawings, and more particularly to
The clog 10 includes an upper 12, a sockliner 14, and a sole 16. The upper 12 is attached to the sole 16 using techniques know in the art. In one configuration, the upper is affixed to sole such as by gluing and/or sewing. In another configuration (not shown), the upper is formed (e.g., molded) as one-piece with the sole. The upper 12 is shaped to define a volume for receiving a foot of the wearer therein and has an opening 18 for passage of the foot into the volume. As is typical with clog footwear, the upper 12 includes a very low heel for allowing the wearer to easily slide her foot into and out of the clog 10. It is understood that the clog could be heelless. The upper 12 may be made of leather or other material (including synthetic and natural materials) conventionally used in uppers and may be lined or unlined. As shown, the exterior surface of the upper 12 can have various patterns, indicia, or stitch lines for aesthetic purposes. Because the construction of the upper 12 can be conventional and well known in the art, it will not be described in further detail.
As illustrated in
Referring to
The sole 16 further includes a plurality of circular openings 34 for allowing assess to each of the cavities 32 therein. The openings 34 have a diameter that is less than a maximum diameter of the cavities. It is understood that the openings and cavities can have other configurations without departing from the scope of this invention. The use of the openings and cavities will be described in detail below. Although the construction of the sole of one embodiment is described above, it is envisioned that the sole may have other constructions without departing from the scope of the present invention.
Referring now to
The sockliner 14 has a surface area that is less than the surface area of the sole 16. More specifically, the surface area of the sockliner 14 is approximately equal to the surface area of the recess 26 in the sole 16, and the sockliner can be received in the recess so that the upper surface of the sockliner is generally flush with the periphery ledge 24 of the sole (
As shown in
When the tabs 40 are being pushed through the openings 34 in the sole 16, the heads 44 of the tabs deform to thereby allow the wider heads to pass through the opening and into the cavities 32. Once the tabs 40 on the sockliner 14 are inserted into the cavities 32 of the sole 16, the large diameter heads 44 rebound to substantially their original shapes to inhibit removal or slippage of the sockliner with respect to the sole. The sockliner 14 can be disengaged from the sole 16 by pulling upward on the sockliner in a direction away from the sole. Thus, the sockliner 14 can be removed, cleaned and reattached or removed and replaced.
As shown in
As will apparent to those skilled in the art, the clog sneaker 10 of the present invention may be assembled using various conventional and well-known methods. The sockliner and sole of the present invention, however, can both be manufactured (e.g., molded) and assembled at the same manufacturing location thereby reducing production time and costs. It is not necessary to use adhesive or stitching that would be carried out at a different location.
In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results obtained.
When introducing elements of the present invention or the preferred embodiment(s) thereof, the articles “a”, “an”, “the” and “said” are intended to mean that there are one or more of the elements. The terms “comprising”, “including” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.
As various changes could be made in the above without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
