Definitions

• the present invention relates to footwear, in particular overshoes or galoshes that are intended to be worn over another shoe for protection of the shoe from wet and other harmful conditions.
• overshoes for personal use, as opposed to industrial or commercial applications, see for example JP2004105695, FR 2608024, WO 2004023915, US Patent No. 2,479,006.
• the emphasis on designing such overshoes has been functionality in terms of an overshoe that may fit over a variety of shoes, and is hard wearing. Such overshoes in view of their appearance are not in general suitable for wearing over fashion shoes.
• An overshoe has been proposed in U.S. Patent No. 1 ,604,954, of lightweight waterproof construction for wearing over a dress slipper, and is formed of a transparent top part and a sole part.
• the top part has an inner lining of for example silk with an outer lining of thin transparent rubber.
• the top part is of one piece construction with gussets on each side to permit the overshoe to be pulled over a foot and to fit snugly.
• the overshoe described lacks practicality, even for fashion wear.
• the one piece upper part is liable to stretch and/or split.
• the materials proposed, with a layered construction, increase expense.
• EP-A-0346005 discloses a shoe cover, primarily for decorative purposes for changing colour of the shoe, formed of a one- or two-piece blank, which covers both inner and outer surfaces of the shoe.
• the cover does not cover the heel of the shoe but has an aperture through which the heel extends. The construction would not be suitable for protecting from rain.
• FR-A-1139328 discloses a cover for the stiletto heel of a shoe.
• the purpose of the cover is functional, for protection of the shoe while driving a car.
• an overshoe comprising a plurality of panels including at least a first inner side panel and a second outer side panel, said plurality of panels being formed of a polymer material that has flexibility and resilience, and said plurality of panels being secured together along adjacent edges whereby to provide an overshoe having areas for fitting closely around the upper, sole, instep and heel of a shoe, and a relatively thick sole sheet member bonded to a sole area of said panels.
• a releasable fastener means is positioned within the upper part, whereby when the fastener means is opened, said flexibility and resilience permits the overshoe to be pulled over a shoe, and when the releasable fastener means is closed, the overshoe may fit snugly over the shoe.
• an overshoe is provided that is compatible with, or may even enhance, the appearance of a fashion shoe worn by the user.
• the transparent nature of the material permits the inner shoe to be seen; the material may be partially transparent with a decorative pattern formed within the material. Alternatively or in addition decorative tags, flaps and edgings may be provided.
• the material of the overshoe panels may be a polyester mixed with rubbery materials, or a PVC material with blended materials to give the PVC its desired qualities of flexibility, resilience and strength. Such material are commercially available, and are for example marketed by Giovanni Crespi S.p.A, of Legnano-Milano, Italy - see www.Crespi.it.
• the characteristics of the material permit the parts of the overshoe to be bonded or sewn together, and the join lines may provide extra strength and reinforcement.
• a securing by stitching has the advantage that the stitch line provides a degree of flexibility and strength that is desired with footwear, where large stresses may arise during use.
• the base regions of the two side panels may have a plurality of flaps that are sewn together to provide an instep area and a sole area (and conceivably a heel section), which is stiffened and reinforced by the stitch lines, and to which the sole sheet member is affixed
• the sectipns may be secured together by ultrasonic welding. This is to be preferred for lower cost, and for providing a more watertight join line.
• the welding is carried out using a Cera Rotosonic tool, which includes a rotating wheel with a knurled rim through which ultrasonic vibrations are transmitted; see www.cerafrance.fr - Cera, Rue de 8 Mai BP12, 42390 Villars, France.
• the method of fabrication or manufacture of the overshoe is essentially inexpensive, in that expensive molds are not required; the panels may simply be cut from a sheet of material and then secured together.
• the sole sheet member is provided for prolonged use and may be formed of a hardwearing synthetic rubber, between say 1 mm and 5mm thick.
• the releasable fastener means may comprise a zip fastener, Velcro tape, a flap with popper fasteners, a lace received in eyelets, a buckle, or any other convenient means.
• the fastener means may be positioned along one of the sew lines at the front or rear of the overshoe. Alternatively, the fastener means may be positioned in one of the side panels of the overshoe.
• a base panel section is provided, in addition to said side panels, consisting of one or more panels.
• Such base panel section may comprise a heel section formedi of elongate first and second side panels that extend along the length of a heel; and, an elongate inner panel that extends between the first and second side panels, along the length of the heel.
• the three panels are secured together along adjacent edges.
• This provides a strong construction that may fit very closely to a stiletto heel for example.
• the overshoe of the invention may be applied to any fashion shoe with a raised heel.
• the heel section may be over dimensioned in its length so as to permit cutting to a desired length for fitting a particular shoe.
• the base panel section may comprise a single base panel that defines the sole, instep and inner part of the heel.
• Said side panels define the outer parts of the heel.
• the base panel and side panels are joined along the edges of the sole and instep, and along the heel to form the overshoe. Since this only requires three panels, this represents a very economic way of forming the overshoe.
• the side panels are preferably of similar shape so that the overshoes of the present invention have a degree of symmetry so that an overshoe may be equally fitted both on left and right feet, decorative details permitting.
• Providing the upper part of the overshoe in accordance with the invention with first and second side panels, has a particular advantage in that the overshoe may be laid flat when not in use with the two side panels on top of one another, and the sole part folded on top. The side panels may then be folded
• a srhall holder, carrier, or pouch is desirable provide to receive a pair of such overshoes, such that the holder may be carried in one hand as a fashion accessory or be carried in a lady's handbag.
• the carrier may be desirably formed as of the same material as the overshoe, and may comprise a single long section that is folded over to form the carrier sides and a closure flap. Two small edge lengths are provide that are secured to the edges of the carrier sides to form the container for the overshoes.
• the present invention provides a overshoe pack comprising first and second overshoes folded up and received in a container, each of the overshoes being as set forth above
