DETAILED DESCRIPTION

(11) The present disclosure relates generally to apparatus and methods for constructing ice structures. FIG. 1 is an upper perspective view of an example apparatus 10 for construction of a structure from ice, according to some embodiments. In some embodiments, the apparatus 10 may include multiple tubes 12. In some embodiments, the tubes 12 may be disposed in an upright or vertically-oriented position and have closed bottoms 14, such that each of the tubes 12 holds liquid, such as, for example, water. In some embodiments, the tubes 12 may be spaced apart from each other to facilitate contact of the tubes 12 with cooling air or warming air/liquid.

(12) In some embodiments, each of the tubes 12 may have a constant inner diameter. In further detail, in some embodiments, an inner diameter of a particular tube 12 may be constant along an entire length of the particular tube 12. The constant inner diameter of the particular tube 12 may facilitate formation within the particular tube 12 of an icicle that has a constant diameter along an entire length of the icicle.

(13) In some embodiments, the tubes 12 may have various lengths and/or inner diameters, depending on, for example, a desired size of icicle. In some embodiments, the tubes 12 may be between approximately 30 and 36 inches, which may facilitate formation of icicles between approximately 30 and 36 inches in length, within the tubes 12. In some embodiments, the tubes 12 may have inner diameters between approximately 0.5 inches and 2 inches. A particular icicle that is between approximately 30 and 36 inches, and/or has an inner diameter between approximately 0.5 inches and 2 inches, may provide icicle strength as well as size for construction of detailed or ornate ice structures. The particular icicle that is between 30 and 36 inches may also be broken in half to provide smaller icicles having strength and size for construction of detailed or ornate ice structures.

(14) In some embodiments, each of the tubes 12 may include a top 16 and a bottom 14 and a lumen extending therebetween. In some embodiments, the tubes 12 may be constructed of any number of materials. In some embodiments, the tubes 12 or pipes may be constructed of polyethylene, high density polyethylene (HDPE), cross-linked polyethylene or cross-linked HPDE (e.g., PEX), polypropylene, polyvinyl chloride (PVC), metal, or another material.

(15) Referring now to FIG. 2, in some embodiments, the bottoms 14 of the tubes 12 may be sealed or closed using any number of suitable means. For example, the bottoms 14 may each include a barb plug 18, such as, for example, a brass or plastic PEX barb plug, which may close the bottoms 14 and allow the tubes 12 to hold liquid. In some embodiments, the barb plug 18 may be secured via a crimp ring 20, clamp, or another suitable means. In some embodiments, the tops 16 of the tubes 12 may be open such that icicles within the tubes 12 may emerge from the tops 16 when the tubes 12 are placed in a warming bath or subjected to non-freezing air. In some embodiments, icicles harvested from the apparatus 10 may be harvested and used to construct an ice structure using any of the methods described in U.S. Pat. No. 8,511,042, filed Jan. 10, 2011, which is hereby incorporated by reference. In some embodiments, the open tops 16 may allow liquid to readily flow into the tops 16 from the warming bath to refill the tubes 12 after the icicles are removed from the tubes 12.

(16) Referring back to FIG. 1, in some embodiments, the apparatus 10 may include a container with open sides that allows transport of the tubes 12 as well as ready and even contact of the tubes 12 by cooling air and/or warming liquid. In some embodiments, the container 22 may include a frame 24 for transport of the tubes 12. In some embodiments, each of the tubes 12 may be disposed within the frame 24.

(17) The frame 24 may include any number of configurations that allow transport of the tubes 12 and even contact of the tubes 12 by cooling air and/or warming liquid. In some embodiments, the cooling air and/or warming liquid may fully surround each of the tubes 12 disposed within the frame 24 to evenly contact the tubes 12. In some embodiments, the frame 24 may include one or more of the following: a base 26, one or more side shafts 28, one or more bottom rails 30, and one or more top rails 32.

(18) In some embodiments, the top rails 32 and/or the bottom rails 30 may be coupled with the one or more side shafts 28. In some embodiments, the side shafts 28 may be spaced apart. In some embodiments, the side shafts 28 may be coupled with the base 26. In some embodiments, the side shafts 28 may be vertically-oriented and/or the top rails 32 may be horizontally-oriented. In these embodiments, the frame 24 may include a rectangular shape. In some embodiments, the base 26 may be configured to contact a bottom 14 of the tubes 12 and/or support the tubes 12. In some embodiments, the base 26 may be planar and/or extend across a bottom of the frame 24.

(19) In some embodiments, the frame 24 may include one or more coupling elements for coupling the frame 24 to a crane 36 or other device for transport of the frame 24. For example, the frame 24 may include one or more handles 38 which may be coupled to one or more hooks extending from the crane 36 or a connector element attached to the crane 36. In some embodiments, the handles 38 may be disposed on the top rails 32 or another suitable location. The coupling elements of the frame 24 may include hooks, fasteners, or any other suitable coupling element.

(20) In some embodiments, the apparatus 10 may include one or more support sheets 40. Referring now to FIG. 3, the support sheets 40 may include one or more holes 42 sized and configured to secure the tubes 12. In some embodiments, the support sheets may be disposed within the frame 24 of the container 22. In some embodiments, the support sheets 40 may be coupled to the frame via any number of suitable means, including, for example, screws, pins, stakes, etc. In some embodiments, a first support sheet 40a may be disposed proximate the bottoms of the tubes and a second support sheet 40b may be disposed towards a middle portion of the tubes, as illustrated in FIG. 1. In some embodiments, the support sheets 40 may be thin, such as, for example, 0.5 inches or less, so as not to impede contact of the tubes 12 by cooling air and/or warming liquid. In some embodiments, a particular support sheet 40 may be coupled with the frame 24 to secure the particular support sheet. For example, a particular support sheet 40 may be coupled with the base 26 or one or more intermediate rails 34 of the frame 24 to secure the particular support sheet 40.

(21) Referring now to FIG. 4, in some embodiments, the tubes 12 may be filled with liquid and placed in a freezer 44. In some embodiments, the freezer 44 may be a temperature to freeze the liquid within the tubes or less than 32 C. In some embodiments, first and second ends 46a, 46b of the freezer 44 may be entirely open, as illustrated in FIG. 4, or partially open. In some embodiments, the first and second ends 46a, 46b may include one or more fans such that ambient air is circulated through the freezer 44, which may speed freezing of the liquid in the tubes. In some embodiments, the freezer 44 may include a lid 48, which is illustrated in an open position in FIG. 4. Alternatively, the apparatus 10 may be placed in any location where the temperature is below freezing (e.g., outside) to cause liquid within the tubes to freeze.

(22) Referring now to FIGS. 5A-5B, in some embodiments, a warming bath 50 may include a container filled with heated liquid, such as, for example, water. In some embodiments, the warming bath 50 may incubate the frozen icicles within the tubes 12 at a temperature above freezing over a period of time. In some embodiments, the warming bath 50 may incubate the frozen icicles within the tubes 12 at a constant temperature. In some embodiments, the temperature of the liquid in the warming bath 50 may be between 32 C. and 100 C. In some embodiments, the temperature of the liquid in the warming bath 50 may be about 60 C. to 70 C., 70 C. to 80 C., 80 C. to 90 C., or 90 C. to 100 C. In some embodiments, the container of the warming bath 50 may include a lid 52, which may be insulated.

(23) Referring now to FIG. 6, in some embodiments, a method 60 of constructing a structure from ice may begin at block 62. At block 62, the tubes 12 may be placed in the freezer 44 (or another freezing location) until liquid within the tubes 12 freezes into icicles. Block 62 may be followed by block 64.

(24) At block 64, the tubes 12 containing the frozen liquid may be transported from the freezer 44 to the warming bath 50 (or to a location where the tubes will be subjected to non-freezing air). Block 64 may be followed by block 66.

(25) At block 66, the icicles that emerge from the tubes 12 in response to warming the tubes 12 within the warming bath 50 may be retrieved. In some embodiments, a portion of a particular icicle may emerge from the top 16 a particular tube 12 automatically in response to the tube 12 being placed in the warming bath 50 for a particular period of time. In some embodiments, the portion of the particular icicle may be manually pulled to remove the icicle from the particular tube 12. In some embodiments, an entirety of a particular icicle may emerge from the a particular tube 12 automatically in response to the tube 12 being placed in the warming bath 50 for the period of time and/or may float in the warming bath 50 prior to retrieval. Block 66 may be followed by block 68.

(26) At block 68, the icicles may be attached to each other to form a framework of icicles. Alternatively, the icicles may be attached to existing ice structures or other structures or materials. Although illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. For example, the method 60 may include submerging the tubes 12 in the liquid in the warming bath 50 to fill the tubes 12 with the liquid. In some embodiments, the method 60 may include transporting the tubes 12 containing the liquid from the warming bath 50 to the freezer 44.

(27) In some embodiments, the method 60 may include providing one or more of the following: the tubes 12, the frame 24, and the one or support sheets 40. In some embodiments, the method 60 may include coupling the support sheets 40 to the frame 24. In some embodiments, the method 60 may include placing the tubes 12 within the holes 42 of the support sheets 40 to secure the tubes 12 within the support sheets 40 and the frame 24.

(28) In some embodiments, the method 60 may include coupling a crane 36 or another transport device to the handles 38 or other coupling elements of the frame 24 to transport the tubes 12 from the freezer 44 to the warming bath 50 and/or from the warming bath 50 to the freezer 44.

(29) Referring now to FIG. 7, a welded wire structure 70 may be horizontally-oriented and/or disposed on a support structure 72. The term welded wire refers to the fact that the wires are welded together at each intersection. These wires may be overlapped (as shown in FIG. 7) or weaved. Support structure 72 can include vertically oriented legs that elevate the welded wire structure 70 above the ground to allow icicles to form on and hang from the welded wire structure 70 as water is sprayed overtop the structure (e.g., by using a sprinkler). In some embodiments, wires of the welded wire structure 70 may overlap to form squares or rectangles, which may provide improved formation of the icicles.

(30) Referring now to FIG. 8, in some embodiments, a method 80 of constructing a structure from ice may begin at block 82. At block 82, the welded wire structure 70 and/or the support structure 72, which may be coupled to the welded wire structure 70, may be provided. Block 82 may be followed by block 84.

(31) At block 84, a liquid, such as, for example, water, may be delivered to the welded wire structure 70 at a temperature and flow rate designed to permit growth of the icicles on the welded wire structure 70 in a low-temperature environment. For example, a sprinkler or sprinkler system can be employed to spray water over the welded wire structure 70. In some embodiments, the welded wire structure 70 may be horizontally oriented and/or disposed on the support structure 72 to elevate the welded wire structure 70. In some embodiments, the icicles harvested from the welded wire structure 70 may be used to construct an ice structure using any of the methods described in U.S. Pat. No. 8,511,042, filed Jan. 10, 2011, which is hereby incorporated by reference.

(32) The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description.
