This application claims priority to and is based on U.S. Patent Application No. 61/477,713, filed Apr. 21, 2011, entitled “Folding Rotatable Umbrella,” the entire disclosure of which is incorporated by reference herein in its entirety.
FIELD OF THE INVENTIONThe invention relates generally to folding umbrellas for use in various toys. More specifically, the invention is directed to a folding umbrella which is configured to selectively transition between an opened configuration and a closed configuration, wherein the umbrella may be rotated about the vertical axis between the opened configuration and closed configurations.
BACKGROUNDUmbrellas and canopies have long been incorporated as accessories in toys. Toy dolls carrying an umbrella or toy carriages utilizing a canopy to protect the carriage and its contents are well known in the art. A few examples of the use of umbrellas and canopies in toys may be seen in U.S. Pat. No. 4,365,819 to Bart, and U.S. Pat. No. 1,186,005 to Kessler. However, the prior art teaches the use of symmetrically shaped umbrellas and canopies incorporated into toys, which may not adequately protect and/or cover an asymmetrically shaped toy. Furthermore, the prior art generally teaches a fixed umbrella or canopy, which lacks the added play features of extension and retraction. Finally, the prior art fails to teach an umbrella capable of unfolding in one orientation, and rotating to a second orientation to better accommodate the shape of the toy and its contents.
Accordingly, it is desirable to provide a folding umbrella capable of being transitioned between a closed configuration and an opened configuration, such that the umbrella is capable or rotating about the vertical axis at or about the opened configuration, to better align with the toy and its contents. It is further desirable to provide a folding umbrella configured to avoid contacting the toy and/or contents of the toy, when transitioning the umbrella from the closed configuration to the opened configuration.
SUMMARYIn one embodiment of the invention, a folding umbrella is provided comprising a frame, a central tube, and a cover. The frame comprises a runner upward and downward slidably attached to the central tube, and at least three ribs with one end of each rib pivotally attached at or near the top of the central tube. The frame further comprises at least three stretchers each pivotally attached to the runner at one end of each stretcher, with each stretcher further attached to about the near midpoint of one, and only one, of the at least three ribs at the opposing end of each of the three stretchers. The umbrella further comprises a cover spanning the frame and attached to the distal ends of the at least three ribs, the cover configured to expand (defining an opened configuration) and collapse (defining a closed configuration) when sliding the runner on the central tube. In the present embodiment, the frame and cover are rectangular in shape to better accommodate a rectangular toy. Although three ribs and three corresponding stretchers have been provided, additional ribs and stretchers may be utilized as necessary.
In another embodiment, the umbrella is configured in an alternative asymmetrical shape to better accommodate an asymmetrically shaped toy and/or the contents of a toy. In a further embodiment, the asymmetrical umbrella may be transitioned from a closed configuration to an opened configuration with the umbrella in a first orientation, thus avoiding contact with the toy, and vertically rotating the umbrella to a second orientation, to better align with the toy.
In an embodiment of the invention, the umbrella further comprises a trigger for actuating transition of the umbrella from the closed configuration to the opened configuration. In one embodiment, the trigger incorporates a resilient member biased towards the opened configuration to realize transition of the umbrella from the closed configuration to the opened configuration. In another embodiment, the trigger incorporates a resilient member biased towards the closed configuration to realize transition of the umbrella from the opened configuration to the closed configuration.
In one embodiment, a portion of the surface of the central tube of the umbrella may be helical to rotate the umbrella frame in the vertical axis. In another embodiment, the umbrella may comprise a torsion spring positioned between the central tube and runner, and configured to rotate the umbrella frame about the central tube in the vertical axis.
In one embodiment, the umbrella may further comprise at least one latch configured on the central tube to maintain the umbrella in the opened configuration and/or closed configuration.
In yet another embodiment, the umbrella further comprises a base for housing the umbrella in the closed configuration. In yet another embodiment, the base and/or umbrella may be attached to a vehicle, such as a carriage.
Other objects, features and advantages of the invention will be understood more readily after consideration of the Detailed Description taken in connection with the accompanying drawings.
In operation, the frame 12 is configured to horizontally expand the at least three ribs 16 by positioning the runner 18 proximal to the ribs 16, thus defining an opened configuration. Conversely, positioning the runner 18 a distance away from the ribs 16, collapses the at least three ribs 16, defining a closed configuration. The at least three stretchers 20 each act as a fulcrum lever between the at least three ribs 16 and runner 18. Vertically sliding the runner 18 on the central tube 14, forces the at least three stretchers 20 to expand and contract the at least three ribs 16 and attached cover 22. A resilient member 30 is configured about the runner 18 and central tube 14 and biased to position the runner 18 proximal to the ribs 16, prompting the umbrella 10 towards the opened configuration. Alternatively, the runner 18 may be manually configured vertically on the center tube 16 to achieve the opened configuration and closed configuration. In a further embodiment, at least one latch (not shown) may be incorporated on the central tube 16 to retain the umbrella 10 in the opened configuration and/or closed configuration.
The frame 12 is further configured to rotate approximately ninety degrees about the central tube 14 in the vertical axis, when the umbrella 10 is in or near the opened configuration. In one embodiment, the central tube 14 comprises a partially helical surface at about the top of the central tube 14 to rotate the frame 12 approximately ninety degrees. As the umbrella frame 12 and cover 22 are rectangular in shape, the umbrella 10 may be transitioned from the closed configuration to the opened configuration with the length of the umbrella perpendicular to the length of the carriage 26. When the umbrella 10 is in or near the opened configuration, the frame 12 and cover 22 are prompted to rotate approximately ninety degrees about the central tube 14 in the vertical axis, aligning the length of the umbrella parallel with the length of the carriage 26. The delayed rotation of the umbrella 10 allows the umbrella 10 to be unfolded into a first orientation, avoiding contact with the carriage 26 and/or carriage contents, and subsequently rotated to a second orientation to fully encompass the carriage 22.
In
The frame 12, central tube 14, base 24, and stand 28 may be fabricated from any suitable material, or combination of materials, such as plastic, foamed plastic, wood, cardboard, pressed paper, metal, derivatives thereof, and combinations thereof. The cover 22 may be fabricated from any suitable material, or combinations of materials, such as plastic, foamed plastic, pressed paper, supple natural or synthetic materials including, but not limited to, cotton, elastomers, polyester, plastic, rubber, derivatives thereof, and combinations thereof. Suitable plastics may include high-density polyethylene (HDPE), low-density polyethylene (LDPE), polystyrene, acrylonitrile butadiene styrene (ABS), polycarbonate, polyethylene terephthalate (PET), polypropylene, ethylene-vinyl acetate (EVA), or the like. Suitable foamed plastics may include expanded or extruded polystyrene, expanded or extruded polypropylene, EVA foam, derivatives thereof, and combinations thereof.
The resilient member 30 and bias member 40 are defined herein as a bias member which compresses (and recovers) in an at least a generally linear direction, including, but not limited to, a spring, a resilient plastic, or a rubber. The resilient member 30 and bias member 40 may be fabricated from any suitable material, or combinations of materials, such as supple natural or synthetic materials including, but not limited to, plastic, metal, elastomers, polyester, rubber, derivatives thereof, and combinations thereof.
