BACKGROUND OF THE INVENTION
The present invention relates to an extension apparatus for rainwater downspouts. More specifically, the present invention relates to a multi-piece, articulated extension apparatus that is attachable to the lowermost portion of an existing rainwater downspout.
Typical building construction may include a gutter and downspout system to collect rainwater and divert it away from the building. A downspout extension may be attached to the downspout to ensure the collected rainwater does not accumulate too close to the building and to direct it a distance away from the building. A fixed, one-piece extension may solve the problem of water accumulation, but it may also present other problems. For example, mowing the lawn is made more difficult when for example, the extension must be moved each time the adjacent lawn is to be mowed. The mower must stop to remove the extension and after mowing, must revisit the downspout to reattach the extension. This procedure takes time and is inconvenient.
SUMMARY OF THE INVENTION
The present invention provides an improved extension apparatus for rainwater downspouts that overcomes the previously described problems with typical fixed extensions. The extension apparatus comprises a multi-piece, articulated device that is attachable to the lowermost portion of an existing rainwater downspout. The apparatus includes a plurality of downspout extension members of varying lengths wherein at least two of the extension members are joined at a pivotable joint. The articulated extension apparatus is movable about the pivotable joint from an extended, in use position, to a displaced position. The apparatus is moved to the displaced position when lateral pressure is applied to an extension member, as by a lawnmower for example, and the extension member rotates on the pivotable joint. The apparatus is further configured to return the displaced extension member to the extended, in use position when lateral pressure terminates.
The extension members of the disclosed apparatus further include side panels. The extension members are connected at each side panel by elastic members. While an extension member pivots laterally about the pivotable joint in response to displacement caused by outside stimuli such as a lawnmower during lawn maintenance, when the stimuli ceases, the elastic members cause the extension member to automatically pivot and return to the extended, in use position.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Although the disclosure hereof is detailed, and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structures. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
With attention to the Figures, an articulated extension apparatus 10 according to the present invention may be seen. As viewed particularly in FIGS. 1-4, the apparatus 10 preferably includes at least a first extension member 12 and a second extension member 14. The first and second extension members 12, 14 are pivotally connected at a pivot point 16. The pivot, point 16 includes a pivot aperture 18A in the first extension member 12, a pivot aperture 18B in the second extension member 14 and pivot hardware, seen as a pull pin 20 in these views. As may be further seen, the first member 12 may include an elbow 22 having a first elbow end 24 configured for mating attachment with the lowermost portion of a downspout 26, although it is within the scope of the present invention to provide a first extension member 12 that has a linear configuration and no elbow (not shown). The first member 12 further includes a second end 28 which is adapted for attachment to the second extension member 14 and includes the pivot aperture 18A. The second extension member 14 includes a first end 30 and a second end 32, with the first end 30 being configured for mating attachment to the first member 12 and including a pivot aperture 18B. The second end 32 of the second extension member 14 is configured for optional mating attachment with another extension member (not shown), if desired. Extension members 12, 14 for use with the present apparatus 10 may be of varying lengths, and may be composed of a polymer such as PVC, metal, or other suitable material.
As further seen in FIGS. 1-5, each of the extension members 12, 14 includes opposed side panels 34 each having a side panel 34 outer surface 36. Each side panel 34 outer surface 36 preferably includes at least one anchor device, such as the eye rings 38 shown, although other suitable devices may be used. An elastic member 39, such as the elastic cord 40 and S-connectors 42 arrangement shown, may be used to further connect the first and second extension members 12, 14. As illustrated, the elastic member 39 includes opposed elastic member ends 44, with each end 44 being attached to a corresponding anchor device 38 on one of the extension members 12, 14. In use, the elastic member 39 supports the apparatus 10 in the fully extended position (see FIG. 7B), while providing sufficient elasticity to allow the second extension member 14 to articulate at the pivot point 16 (see FIG. 7A) when lateral pressure is applied. The elastic member 39 further draws the second extension member 14 back to the fully extended position once lateral pressure ceases, as will be discussed.
With particular attention to the views of FIGS. 4 and 5, it may be seen that the first extension member 12 second end 28 may include a pair of opposed flexible flaps 46. The flaps 46 are configured to be received within corresponding slots 48 in the second extension member 14 (see FIG. 5) and are preferably made of a resilient, flexible material, such as a polymer or the like. The flaps 46 interact with the second extension member 14 in the slots 48 to slidingly connect the first and second extension members 12, 14, and to flex when the apparatus 10 is articulated about the pivot point 16. As is shown in FIG. 6, the pivoting action of the second extension member 14 in the direction of arrow A flexes the flaps 46 to thereby allow the apparatus 10 to articulate at the pivot point 16. The flaps 46 further cover any gaps in the side panel 34.
FIGS. 7A and 7B illustrate a method of use for the articulated extension apparatus 10 according to the present invention. As may be viewed, the second extension member 14 is moved in the direction of arrow B as a lawnmower 50 or other ground maintenance device moves in the direction of arrow C adjacent the apparatus 10. The lawnmower 50 or other ground maintenance device contacts and applies lateral pressure on the second extension member 14. The lateral pressure of the lawnmower 50 in contact with the apparatus 10 overcomes the bias of the elastic member 39 and the apparatus 10 pivots as the second extension member 14 moves about the pivot point 16 in the direction of arrow B, The pivoting movement allows the lawnmower 50 to pass the apparatus 10 without the need for the user to stop, disassemble, or otherwise manually reposition the device 10. As the lawnmower 50 continues in the direction of arrow C, and as shown in FIG. 7B, lateral pressure against the second extension member 14 ceases, the bias of the elastic member 39 moves the second extension member 14 in the direction of arrow D, and the apparatus 10 resumes its original position.
The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
