Snow brick

Abstract

The invention relates to molds that are used to craft snow or sand into different shapes. Specifically, the present invention provides a mechanism for compressing the snow or sand, then assisting in the compression of the snow or sand, and/or assisting with the ejection of the same from the mold in order to produce an improved shape.

DETAILED DESCRIPTION

(7) A more complete understanding of the components, processes and apparatuses disclosed herein can be obtained by reference to the accompanying drawings. These figures are merely schematic representations based on convenience and the ease of demonstrating the present disclosure, and are therefore not intended to indicate relative size and dimensions of the devices or components thereof and/or to define or limit the scope of the exemplary embodiments.

(8) Although specific terms are used in the following description for the sake of clarity, these terms are intended to refer only to the particular structure of the embodiments selected for illustration in the drawings and are not intended to define or limit the scope of the disclosure. In the drawings and the following description below, it is to be understood that like numeric designations refer to components of like function.

(9) FIG. 1 is an image of the brick crafting device according to the present invention. The external components are a body shell (1) that forms the rectangular shape from the snow or sand input and the overhead handle (2) that slides through channels along the inside of the body shell to compress the material.

(10) FIG. 2 is a series of images illustrating a 2-piece design. An image of the handle assembly (2a) that travels inside the body shell (1) for compression of the malleable material. The handle has one or more small guide protrusions around its outer periphery that fit in the guide channels of the body. The body shell (1) employs one or more guide channels (2b) around its periphery to guide the handle assembly (2a) to resist turning within the body shell (1) and ensure a close fit on compression. The closed end can include a protruding lip extending around the periphery of the one or more openings, such that the molded press can be prevented from removal from the shell (as seen in 2c). The interconnection fit between guide protrusions and channels (2c) controls the travel of the handle to compress the material and eject it, while preventing the handle from detaching from the body once assembled. Such a male-female interconnection fit can be made of various configurations known in the art, with either portion of the interconnection fit located on either piece of the invention. The handle preferably protrudes from the top of the body shell an adequate distance to allow the handle to travel down and compress the snow or sand material inside the body shell, or it may be depressed into the space defined by the shell in order to produce a smaller shaped brick of malleable material. The handle can be of varying sizes and configurations, and in one embodiment is preferably shaped with enough clearance above the body to be gripped with gloved hands of different aged users (2).

(11) FIG. 3 demonstrates the process of forming a play brick using this embodiment of the present invention shown in FIGS. 1 and 2. With the handle assembly (2a) installed within the body shell (1), the body shell mold (1) is filled with snow or sand (B) (commonly to the top of the mold) and the handle (2) is pushed by said material to its highest position within the body shell (1). During the compression step, the handle assembly is pushed down against a stationary surface until the material is compressed into a harder and better formed shape (B1) inside the mold. The handle may stopped by an internal bevel in the interior of the body shell (1) to allow the handle to be pulled back away from the compressed material, perhaps even to the original position (D). Compression has three effects on the process: first, to press the material, second to better form the final shape, and third to help eject the final brick shape from the mold (F). These actions differentiate the brick maker of the present invention from simple fixed molds of the prior art and supply an improved final shape for play.

(12) FIG. 4 illustrates an alternative design using three parts. The inner handle itself is composed of a single molded piece as well as a crossing reinforcements (3b) that support the structure during compression and resist warping over time. The inner handle has edge grooves (3a) which are aligned to the molded channel guides (1b) of the body shell. The handle assembly of either embodiment could have perforations that would allow snow to be removed from above the inner handle (3c).

(13) By way of example, FIG. 5 illustrates three examples of alternative shapes that use the same technology and process, such as a corner shape (1), a cylinder (2), and a square (3). Other shapes that could apply the same technology and principles include square, triangular, and any other closed polygonal shape.

(14) The production process may utilize injection molding of polymer material to provide adequate flexibility and temperature resistance to the body. Other production methods that could produce similar qualities could be utilized, including but not limited to 3D printing. One embodiment of the present invention would have side walls of approximately between 3-5 millimeters thickness, thereby giving the device a slight degree of flexibility yet be rigid enough to form a sufficiently solid block of material. Potential materials for construction could include polymer plastics as well as thin, non-corroding metals such as aluminum. Different materials could be used for different parts, such as a more rigid or thicker component for the inner handle to resist bending or wear over time. A non-stick coating could also be applied to the interior walls to reduce friction and ease the ejection of the finished brick.

(15) This invention will be expected to be functional and not subject to damage across a wide range of temperature and conditions. Recitation of materials and dimensions are presented by way of example only and should not be construed in any way as limiting the scope of the present disclosure.
