This application is based on and claims the benefit of U.S. Provisional Application No. 61/155,350 filed Feb. 25, 2009, all of which is herein incorporated in its entirety.
BACKGROUND OF THE INVENTIONThis invention relates generally to steam appliances, and more particularly to a flexible steam frame for a steam appliance for use in cleaning various surfaces (e.g., uneven surfaces and corner regions or the like).
Steaming devices used to apply steam to household objects are well known. The uses of the devices vary widely, and may include the application of steam to drapes or other fabrics to ease wrinkles, and the application of steam to objects to assist in cleaning the various objects and surfaces.
In general, nozzles used with the steam appliances do not have large surface areas and a cloth or fabric pad is placed over a steam frame to provide a steaming or cleaning surface. The fabric pad may have Velcro strips to secure to cleats on the steam frame. Typically, a fabric steam pocket is placed around a flat frame with baffles in order to increase the cleaning surface area.
Notwithstanding the wide variety of steam appliances available, it remains desirable to provide additional steam products having improved features, such as, for example, the ability to clean various surfaces (e.g., uneven surfaces and corners or the like). These and other inefficiencies and opportunities for improvement are addressed and/or overcome by the systems and methods of the present disclosure.
SUMMARY OF THE INVENTIONGenerally speaking, in accordance with the invention, a flexible steam pocket frame for use with a steam appliance is provided. In an exemplary embodiment, the flexible steam pocket frame includes a rigid base and/or handle and a plurality of elongated flexible elements such as, wires as bands or fingers that extend from the outlet end of the base to form a skeleton. A flexible steam supply hose connected to a steam generating appliance may be coupled to the inlet end of the base. Alternately, the inlet end of the base may be coupled directly to the nozzle of a steam appliance housing.
The present disclosure also provides for a flexible steam frame for a steam appliance including a base member having a steam inlet and a steam outlet; and a plurality of flexible elements extending from the base at the steam outlet to form an internal space for distribution of steam. In one embodiment, the elongated elements are thin metallic or plastic members about 5 to about 8 inches long connected to the outlet end of the base. They generally are stainless steel and may be individual mounted elements or formed from a common base and fan out in an arc between about 20 to about 90 degrees. Bands are flat with are inwardly bent end sections about one-half to about one inch long with the ends overlapping. Wires extend out from the base and may be bent 90 degrees at the end and return to the base. A steam towel substantially matching the shape of the frame formed by the elements is fitted over the frame. There may be an opening on one or two sides to allow the towel to be placed over the bands and secured by Velcro strips attached to the open edge or edges. The towel can be secured by a plastic zipper. The steam hose may be permanently or removably attached to the inlet end of the base.
Accordingly, it is an object of the present disclosure to provide an improved flexible steam frame for a steam appliance.

At least one advantage of having twisted or curved wires 104 is that the number of wires in the frame 101 may be kept to a minimum, thereby reducing the rigidity of the frame 101, which reduces the strain on the user's hand during use. In addition, the twisted or curved wires 104 provide increased support for the towel. This configuration also has improved properties for bending or flexibility, and also reduces the strain and/or fatigue of the materials used in the frame 101. As depicted in
In an alternative embodiment and as depicted in
Frame 201 further includes a plurality of wires or bands 209 (e.g., elastic metallic wires, plastic wires, etc.) that extend from base 203. In an exemplary embodiment, wires 209 are flexible stainless steel wires. Frame 201 typically includes at least one upper wire 209a arranged in a first plane and at least one lower wire 209b arranged in a second plane, with the wires 209a, 209b extending distally from base 203. In exemplary embodiments, frame 201 includes at least one upper wire 209a, at least one lower wire 209b, at least one first side wire 209c, and at least one second side wire 209d, all of which extend distally from base 203. In one embodiment, frame 201 includes an upper set of wires 209a, a lower set of wires 209b, and two side sets of wires 209c, 209d, all of which extend distally from base 203. Upper set of wires 209a and lower set of wires 209b may take the form of a substantially planar, rectangularly shaped set of wires, as shown in
In use and as shown in
In general, the upper set of wires 209a, lower set of wires 209b, and two side sets of wires 209c, 209d are configured and dimensioned to flex and/or bend to take the shape of the towel 215. For example, when the towel 215 is removed from the wires 209, the wires 209 may be substantially straight (e.g., the wires 209 may be substantially straight and substantially perpendicular to a plane of the base 203, as shown in
Moreover, when the frame 201 with the towel 215 positioned over the wires 209 is pressed against a surface to be cleaned (e.g., a substantially flat surface), the frame 201 remains relatively stiff, which improves the scrubbing action of the towel 215 on the cleaning surface. In exemplary embodiments, when the frame 201 with the towel 215 positioned over the wires 209 is pressed against a surface to be cleaned, forces inside the towel 215 and/or wires 209 immobilize the wires 209, and creates a link between at least an upper wire 209a and a lower wire 209b, thereby increasing support for the towel 215. For example and as shown in
In an exemplary embodiment and as shown in
By providing a steam frame with flexible wires or bands that form a skeleton or flexible frame with a steam towel to form an internal space for distribution of steam, the device has the needed flexibility for cleaning various surfaces (e.g., uneven surfaces and tight corner areas). The added flexibility of attaching to a steam hose of a steam appliance or directly to the steam outlet of a hand steamer provides added utility.
