This application claims the benefit of U.S. Provisional Application No. 62/047,858 filed on Sep. 9, 2014. The above identified patent application is herein incorporated by reference in its entirety to provide continuity of disclosure.


BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to building structures. More specifically, the present invention provides a playhouse assembly comprising one or more contoured upper wall elements connected to one another to form an upper wall of a dome-shaped structure, wherein snow is used to construct a lower wall thereof. The upper wall and lower wall connect to one another to define an enclosed area. A transparent window is disposed on the upper wall of the structure in order to form the peak thereof. In an alternate embodiment, a lower wall is provided comprising one or more lower wall elements connected to one another and to the upper wall, rather than using snow to construct a lower wall.
Many children and adults enjoy playing in the snow and constructing playhouses, such as forts and igloos. However, it is difficult to construct a dome shaped roof of an igloo in a way that ensures the roof will not collapse. If the roof collapses while a person is inside of the igloo or fort, the individual may be injured or stuck underneath the heavy snow. Furthermore, constructing a fort or igloo is difficult and time consuming. Children spend the majority of their play time constructing the playhouse rather than using their creativity and imagination playing therein. Therefore, there exists a need in the prior art for a device that helps users to efficiently construct a safe fort or igloo.
Devices have been disclosed in the prior art that relate to building structures. These include devices that have been patented and published in patent application publications. These devices generally relate to structures having a dome shaped housing or frame, such as U.S. Pat. No. 2,879,553, U.S. Pat. No. 7,458,186, U.S. Pat. No. 4,665,664, U.S. Pat. No. 5,916,097, U.S. Pat. No. 6,421,963, and U.S. Pat. No. 3,039,473.
These prior art devices have several known drawbacks. The prior art devices include a dome shaped enclosure having an entranceway. Some of the devices are formed using a plurality of panels and comprise windows along a wall thereof. However, the devices in the prior art fail to provide a lower wall and an upper wall, wherein the upper wall comprises one or more rods adapted to be disposed through the lower walls. Furthermore, the devices fail to provide a transparent window forming the uppermost portion of the present invention.
In light of the devices disclosed in the prior art, it is submitted that the present invention substantially diverges in design elements from the prior art and consequently it is clear that there is a need in the art for an improvement to existing playhouse assemblies.

The playhouse assembly 11 includes an upper wall 13 comprising one or more upper wall elements (as referenced in FIG. 3, 21), wherein each of the upper wall elements connect to one another to form a loop configuration. The upper and lower ends of the upper wall 13 are open so as to provide a user access to above and below the interior of the upper wall 13. Each upper wall element comprises an upper edge 17, a lower edge 22, and opposing lateral edges. A first lateral edge of a first upper wall element is connected to a second lateral edge of a second upper wall element (as referenced in FIG. 3, 32, 33). Preferably, the upper wall 13 is contoured and the cross section thereof comprises a circular shape so as to allow for a dome-shaped structure.
The playhouse assembly 11 further comprises a transparent window 12 disposed on the upper edge 17 of the upper wall 13 so as to allow a user to view outside of the playhouse assembly 11 through the peak thereof. In the illustrated embodiment, the window 12 is dome-shaped and comprises a lower edge 16 having a lip disposed therearound that rests securely on the upper edge 17 of the upper wall 13. In the illustrated embodiment, the upper edge 17 of the upper wall 13 comprises a channel that receives the lip, however, in alternate embodiments, the window 12 may attach to the upper wall 13 by any suitable means, including edges that rest flush on one another.
The upper wall 13 further comprises one or more rods 15 extending from the lower edge 22 thereof. The rods 15 are adapted to be positioned into a lower wall 50 constructed from snow, wherein the walls 13, 50 are used to define an enclosed area. Preferably, the rods 15 extend vertically downwards so as to penetrate an upper end of a wall 50 of snow. In some embodiments, the lower end of each rod 15 is pointed so as to more easily penetrate the snow. The rods 15 are preferably spaced at a fixed distance from one another.
In some embodiments, the playhouse assembly 11 further comprises a template 14 having a first side and a second side, wherein the second side is planar and adapted to rest flush against a horizontal support surface, such as the ground. The template 14 provides a guide to the user when constructing the lower wall 50 from snow. Preferably, the template 14 is disposed in a loop configuration, wherein the width of the template 14 is adapted to indicate to the user the necessary width of the lower wall 50 needed in order to properly receive and secure to the upper wall 13. In this way, a user may initiate building the lower wall 50 on the first side of the template 14. Preferably, the template 14 comprises a circular cross section and the same diameter as the lower edge 22 of the upper wall 13 so as to allow a user to build a lower wall 50 having vertical sidewalls. In some embodiments, the first side of the template 14 includes raised lateral edges, forming a channel therebetween so as to further assist a user in construction of the lower wall 50.
