DETAILED DESCRIPTION OF THE INVENTION
(10) With reference to the drawings in which like reference designators refer to like elements, FIGS. 1 to 8 depict the preferred and alternative embodiments of the instant invention which is generally referenced as a window dressing support device, portable shelf, support device and, or by numeric character 10. There is shown in FIGS. 1-8 a window dressing support device 10 for holding or supporting window dressings above a floor or away from a wall to facilitate convenient cleaning, painting or maintenance of the floor or wall, The instant invention 10 may also be used to hold cleaning and maintenance items when working, such as shower products, car cleaning or detailing items, plants or other items. The support device 10 may be secured to a window or wall, and provides a trough for placing the window dressing when lifted off or above the floor or other items to any surface, including windows, walls, cars, etc. The device 10 is foldable into a rectangular cube for convenient packaging when shipping or sold, storage and relocating. The device 10 is easily moveable to other positions or locations for use throughout a house, office or outside.
(11) With reference to FIGS. 1-8, the preferred embodiment of the window dressing support device 10 provides a portable shelf device that includes a face plate 12 hinged to a base plate 18, at least one hinge 11 defined by the face plate 12 and base plate 18 to pivotally connect the face plate 12 to the base plate 18, left side panel 14 having an inward projecting upper flange 14c, right side panel 16 having an inward projecting upper flange 16c, a left side face plate flange 12a defined by and projecting from the rear surface of the face plate 12, a right side face plate flange 12b defined by and projecting from the rear surface of the face plate 12, at least one left side hinge 15 defined by the left side panel 14 and left side face plate flange 12a pivotally connecting the left side panel 14a to a left end of the face plate 12, at least one right side hinge 17 defined by the right side panel 16 and right side face plate flange 12b for pivotally connecting the right side panel 16 to a right end of the face plate 12, a left side upper flange 14c projecting inward from the free end of the left side panel 14 for supporting a first suction cup 40 and a right side upper flange 16c projecting inward from the free end of the right side panel 16 for supporting a second suction cup 40. The suction cups 40 may have a threaded knob 41 or lever for applying, increasing, decreasing or otherwise adjusting the suction force. The left side panel 14 defines an upper arcuate edge 14a to define upward projecting lobes 14b, a plurality of apertures 14d and lower base plate support flange 14e projecting inward from the lower end or edge of the left side panel 14. The right side panel 16 defines an upper arcuate edge 16a to define upward projecting lobes 16b, a plurality of apertures 16d and lower base plate support flange 16e projecting inward from the lower end or edge of the right side panel 16. The left side panel 14 and right side panel 16 fold outward to facilitate pivoting the base plate 18 outward onto the left side panel flange 4e and right side panel flange 16e and into place at a ninety degree angle with the face plate 12 to support the base plate 18 for use. The face plate-base plate hinge 11 is defined by at least one and preferably a plurality of axles 11a separated by support tabs 11c which are defined on the lower edge of the face plate 12 and at least one and preferably a plurality of C-clamps 11b that align with and snap to the axles 11a. Referring to FIGS. 1-7, the left side panel hinge 15 is defined by at least one and preferably a plurality of axles 15a separated by support tabs 15c which are defined on the inner edge of the left side face plate flange 12a and at least one and preferably a plurality of C-clamps 15b that align with and snap to the left side axles 15a. Still referring to FIGS. 1-7, the right side panel hinge 17 is defined by at least one and preferably a plurality of axles 17a separated by support tabs 17c which are defined on the inner edge of the right side face plate flange 12b and at least one and preferably a plurality of C-clamps 17b that align with and snap to the right side axles 17a. When the left side panel 14 and right side panel 16 are folded inward, the suction cups 40 partially pass through the face plate apertures 22 and base plate apertures 19a for packaging or storage, as shown in FIG. 5. The face plate 12 may be removed for an open shelf as shown in FIG. 6. The base plate 18 includes a plurality of apertures 18b while the side panels 14, 16 include apertures 14d and 16d to provide air flow and prevent static cling as well as reduce weight. The invention 10 may include a flat insert 18a to cover or conceal the apertures 19b
(12) Still referring to FIGS. 1-7, the side panels 14 and 16 are narrow substrates that form a separation as supported by the face plate 12. This provides the effect of a complete side panel without using all the material necessary for a full panel to reduce weight and manufacturing cost. The support device 10 may be stabilized when mounted to a support surface by posts 42 which project from the left side panel 14 below the left side upper flange 14c and right side upper flange 16c, respectfully. The posts 42 are capped with a rubber tip 43 to prevent damage to the support surface.
(13) Now referring to FIG. 8, the support device 10 has a left side face plate flange 12a and right side face plate flange 12b that extend a distance that moves the side panels 14,16, respectfully further from the face plate 12 so the suction cups 40 engage but do not pass through the face plate and base plate 18 when folded inward. In this embodiment, the face plate apertures 22 and base plate apertures 19a are not required.
(14) Now referring to FIGS. 1-5, the face plate 12 and base plate 18 include a plurality of apertures 22,19a,19b, respectively, for an aerodynamic advantage that creates airflow and reduces static to prevent the window dressing from clinging to the plates 12,18 while reducing weight. As the window dressing tends to rest in on the bottom plate 18, the bottom plate 18 preferably has more apertures than the face plate 12. The side panels 14 and 16 may also have apertures 14d, 16d. The device 10, and more particularly the face panel 12, base panel 18, and side panels 14 and 16 are preferably manufactured from polypropylene plastic or comparable substitute for weight reduction and mass production. The device 10 may be manufactured from another material without departing from the scope and spirit of the instant invention 10.
(15) Now referring to FIGS. 5 and 8, the support device 10 is able to fold into a compact form by virtue of the hinges 11, 15 and 17 and the shape of the side panels 14, 16, including the face plate side panel flanges 12a and 12b and the dimensions of the face plate 12, base plate 18, side panels 14, 16 and face plate side flanges 12a, 12b relative to each other. The base plate 18 is pivotally connected to the face plate 12 by at least one and preferably a plurality of hinges 11 that enable the base plate 18 to swing backward over the outside front surface of the face plate 12. Meanwhile, the side panels 14, 16 swing inward over the rear surface of the face panel 12, as shown in FIGS. 5 and 8.
(16) The support device 10 is preferably manufactured from a thermoplastic, plastic or other material amenable to injection molding and mass production. The support device 10 may alternatively be made from fiberglass, aluminum, stainless steel or other rustproof material.
(17) It will be appreciated by persons skilled in the art that the present invention is not limited to what has been particularly shown and described herein above. In addition, unless mention was made above to the contrary, it should be noted that all of the accompanying drawings are not to scale. A variety of modifications and variations am possible in light of the above teachings without departing from the scope and spirit of the invention, which is limited only by the following claims.
