DETAILED DESCRIPTION
[0(1131 An elongated warming device (10), shown in figures 1-6, may be used to prevent snow and ice buildup and accumulation on the roof or on steps. The device (10) comprises a flat deck (20). a U-shaped bracket (30), and a self-regulating heat cable (40).
The device is metal. The flat deck (20) has two long ends and two faces, wherein the first long end is a free edge (21). The U-shaped bracket (30) comprises two sides (31, 32), a back (33), and a tab (34). The two sides (31, 32) and die back (33) form a channel (35), where the opening for the channel (35) is between the ends of the two sides (31, 32). The end of one side (31 or 32) of the U-shaped bracket (30) extends inwards towards the opening of the channel (35) to forrn the tab (34), which holds the heat cable (40) in the channel (35). The U-shaped bracket (30) is attached to the second long end of the flat deck (20) so that the opening of the channel is open towards the flat deck.
The heat cable (40) is in the channel (35) of the U-shaped bracket (30).
_ 7 _ [00141 In one embodiment, the device (10) is configured so that it may be installed under any row of shingles. For example, the device (10) may be installed at the bottom row of shingles right above the gutter or gutter cover as shown in Figure 2. The device (10) may be installed under the second row of shingles, or the third row, as shown in Figures 4 and 5. The device (10) may be installed under any row of shingles up to the top of the roof.
Multiple warming devices (10) may be installed under several rows of shingles.
The width of the tlat deck (20) may vary depending on the application. In some emboditnents the width may be from about 6 inches to about 8 inches.
[0015] In SOMC eMbOdiMCMS, the device (10) is configured so that one or more devices may be installed in the valley of a roof. The device (10) may be installed so that the wire is near the center of the valley or near the shingles, as shown in Figure 3.
The flat deck (20) may be placed under or above the shin.gles. The device (10Imay be installed in the valley of a roof so the self-regulating heat cable (40) is facing the shingles, or facing away from the shingles.
(m16} In some embodiments, the flat deck (20) comprises holes, close to the first long end (21), to allow fasteners to attach the flat deck (20) to the roof. These holes will allow fasteners, such as screws or nails to be used to fasten the device (10) to the roof. The area around the holes may be debossed to allow space for the SCrCW head or nail head.
[0017] The U-shaped bracket (30) creates the channel (35) for the heat cable (40) to fit into. It is installed through the opening of the channel (35). One side of the U-shaped bracket (30) has a tab (34) to prevent the heat cable (40) from slipping out of the channel (35). In some embodiments, the side of the U-shaped bracket (30) opposite to the tab (34) has an elongated bump (36). With both a tab (34) and an elongated burnp (36) the heat cable (40) should be more secure in the channel (35). In some embodiments, the tab (34) is formed from the bend that connects the U-shaped bracket (30) to the flat deck (20).
[oots] In some embodiments, one side (31 or 32) of the U-shaped bracket (30) is co-planar with the flat deck (20). In some embodiments, the side of the U-shaped bracket (30) that is coplanar is side (31), in some embodiments it is side (32). In some embodiments, a bend connects the second long end of the flat deck (20) to one side (31) of the U-shaped bracket (30). In some embodiments, the angle between the flat deck (20) and the side (3 t) of the U-shaped bracket (30) attached to the flat deck (20) is about 90"
or more, such as about 135 or more. In some embodiments, one side of the U-shaped bracket (30) is co-planar with the flat deck (20). In some embodiments, the angle between the flat deck (20) and the side (31) of the U-shaped bracket (30) attached to the flat deck (20) is greater than 180' so that the opening of the channel (35) is partially closed off by the deck (20).
[0019] The elongated warming device (10) may also be used to prevent snow and ice buildup and accumulation on steps. In some embodiments, the device (10) is configured so it may be installed on a step, as shown in Figure 6. The width and length of the device (10) must be appropriate to fit on a step. There may be a warming device (.10)_placed on one or more steps in a stairway. In some embodiments, at least one face of the flat deck (20) has a rough surface texture to prevent slipping. In some embodiments, the face of the flat deck (20) has upward embossments. In some embodiments, the device (10) is made from heavy duty aluminum.
100201 The U-shaped bracket (30) may be attached to the flat deck (20) in several ways when used the device (10) is used on a step, as shown in Figure 6. In some embodiments, one side of the U-shaped bracket (30) is co-planar with the flat deck (20). In some embodiments, the first long end (21) of the flat deck (20) is bent at approximately 90 degrees to the flat deck (20) so the first long. end (21) extends toward tile face of the flat deck (20) that is opposite to that of the U-shaped bracket (30). In some embodiments, a bend connects the second long end of the flat deck (20) to one side (31) of the U-shaped bracket (30) so the flat deck (20) and the side (31) of the U-shaped bracket (30) are at approximately 90 degrees.
[0021] The heat cable (40) heats the warming device (10) to melt ice or snow.
The heat cable (40) may be able to increase the temperature of part of a roof or step so it is warm enough to melt ice or snow. In one embodiment the heat cable (40) is a low temperature self-regulating cable, such as the CHROMALOX brand self-regulating low temperature - 4. -heating cable, available from CHROMALOX Precision Heat and Control, or the equivalent. It is capable of being directly connected to typical household electric service.
It is self regulating so that when the ambient temperature is higher less heat is produced, and when the ambient temperature is lower more heat is produced. It may be jacketed to protect it from exposure to water and the environment. The heat cable (40) can provide enough heat at cold temperatures to inch ice and snow.
[0022] The heat cable (40) is attached to an electrical source. The heat cable (40) may be run inside the downspout then out an opening near the bottom of the downspout to connect to an outlet or hardwired into a circuit. The opening in the downspout may be sealed around the cable to prevent rainwater from leaking out. In another embodiment the heat cable (40) may be run into the attic, and connected to an outlet or hardwired into a circuit through the attic.
foa231 In another embodiment the heat cable (40) is controlled by a switch or a temperature measuring device (10). A switch may be used to manually turn on and off the heat cable (40). A temperature measuring device (10) may be used to turn on the heat cable (40) when the temperature is below a set temperature.
[0024] While the pre-sent disclosure has illustrated by description several embodiments and while the illustrative embodiments have been described in considerable detail, it is not the intention of the applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications may readily appear to those skilled in the art.
