Description

FIELD OF INVENTION

This invention relates to chimney cover, and more particularly, a chimney cover for covering the current aging chimney pipe on the roof of a house or any other building structure.

BACKGROUND OF THE INVENTION

A chimney is a structure that is used to vent flue gases or smoke from a boiler, stove, furnace or fireplace to the outside air. Typically, chimneys are made in a vertical shape for easy flow of the gases to the outer air. A chimney can be made a part of the structure of a house or a building. Generally, chimney pipes are installed from the floor of the house or building structure towards the roof, and are enclosed within the walls of the house of the building. Normally, the pipes are installed at the time when the house or building is being constructed. A chimney is generally made of metal pipes or masonry bricks. Any material used to build a chimney is enclosed within the walls of the house or building, and is usually protected from excessive wear and tear because the chimney inside the wall is not exposed to any environmental elements.

Part of the end portion of the chimney, however, is exposed to the environmental elements causing wear and tear. The end portion of the chimney that vents out the gases in the atmosphere is generally a circular or rectangular. This end portion of the chimney system starts beneath the roof and protrudes upwards through the roof where the chimney is located. The length of the end portion that protrudes from the roof is susceptible to the environmental elements such as rain, snow, heat, etc.

Due to the exposure to the environmental elements, the portion of the end pipe of the chimney system protruding from the roof of a house or a building wears faster than the rest of the unexposed portion of the end pipe or any other portion of the chimney system. One way to prevent this excessive wear is to cover the length of the end pipe protruding from the roof with an artificial chimney top cover. However, the artificial top cover is unable to completely protect the end pipe from further deterioration. A solution to correct this problem is to change the complete chimney system. However, changing the whole chimney system is cumbersome and is very expensive.

Therefore, there is a need of a system that can prevent excessive wear to the exposed portion of the end pipe protruding from the roof of a house or a building without changing the complete chimney system. The system should also be adjustable to be able to be used on any type of roof or roof pitch and with any size & type of the chimney system.

SUMMARY OF THE INVENTION

A covering system that covers an end pipe of a chimney system. A portion of the end pipe protrudes from the roof of a house or building where the chimney system is located. The system comprises of at least two base supports that sit on the roof. A channel spanning around the end pipe of the chimney system that protrudes from the roof. The base supports are attached at the base of the channel. The base has a protruding section whose dimensions are greater than the channel. A collar covering having a first and a second opening. The collar covers the protruding portion of the base by its first opening and receives the channel at its second opening. A crown top base that slides inside of the channel from the top.

For further understanding of the advantages of the present invention, reference should be made to the following description taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

FIG. 1 is a lateral side view 10 of the top of a roof 20 where the end pipe 30 of a chimney system is protruding from the roof of a house or building in which the chimney system is installed. Generally, a portion of the end pipe 30 of the chimney system is inside the roof of a house or building and is connected to the chimney system. The remaining portion protrudes through the roof of the house or the building where the chimney system is located. The portion that protrudes from the roof vents out the gases. This end pipe of the chimney system is generally made of galvanized steel or similar alloy, and is generally circular in shape. However, some end pipes may be rectangular, square, or of any other shape. The protruding portion of the end pipe is susceptible to excessive wear & tear due to its exposure to rain, snow, heat, etc. This wear & tear is in addition to the wear & tear that the pipe normally has due to the gases passing through it. In order to stop the deterioration of the end pipe, it can be changed. However, to change the end pipe of the chimney system is expensive. Alternatively, the end pipe 30 is covered with a channel 40. The channel completely covers the portion of the end pipe that protrudes from the roof; thereby stopping any further deterioration of end pipe 30. The dimensions of the channel 40 are greater than the dimensions of the end pipe 30 that the channel covers. The dimensions of the channel can be customized according to the dimensions of the end pipe 30 of any chimney system, which is to be covered. The dimensions of the channel will depend upon shape and size of the end pipe, which is to be covered by the channel. The end pipe 30 can be circular, rectangular, square, etc. Similarly, the length of the channel will be adjusted according to the length of the end pipe 30 protruding from the roof, which is to be covered by the channel. In the preferred embodiment, the channel is made of stainless steel because it is cost-effective and lasts much longer than galvanized metal. In another embodiment, the channel of the present invention can be made of cooper or galvanized metal. The channel can be made of aluminum also; but it will understood by the persons of ordinary skill in the art that aluminum channel cannot be used only in the oil based chimney system.

In the preferred embodiment, base support 70 is attached using bolts at the end of the channel which will face the roof. The base support 70 is fixed in such a manner so that it can pivot along the longitudinal axis of the channel so as to fit on any angle of the roof or roof pitch. The preferred method of attaching the base support with the channel is by using bolts. However, there may be other ways, such as screws, rivets, etc. that can be used instead of the bolts. Generally, the base support is made of the same material as the channel. The base support is pre-attached with the channel 40 before it is installed on the roof. The channel 40 is then guided to cover the end pipe 30 such that the base support rests on the roof. Once the base support rests on the roof it is fixed on to the roof 20 using nails or screws. A base 80 is then placed and fixed on the roof of the house or building using screws or any other similar method. The base 80 is a generally a roof flashing that has a section 85 on its top protruding from the base's surface. The protruding section 85 of the base 80 generally covers 75% of the surface area of the base 80. The dimension of the protruding section 85 of base 80 is larger than the channel. The dimension of the protruding section 85 of the base 80 is such that it sits on top of the base support 70 and can completely cover the portion of base support 70 which is connected to the channel 40. The base 80 is also fixed on to the roof by screws or other similar means. Typically, the base 80 will completely cover the base support 70. However, a person of ordinary skill in the art may understand that depending upon the type of roof or roof pitch, the base 80 may not be able to completely cover base support 70. The protruding section 85 is generally adjustable, that is, it may be rotated around its circular axis. The flexibility of the section 85 allows the channel 40 to even cover a curved end pipe of the chimney system. The purpose of the base 80 is to act as a stable stand for the channel 40. FIG. 6 shows the placement of the base 80 on top of roof 20. It will be obvious to a person of ordinary skill in the art that there may be other means to provide a stable stand for the channel 40. Generally, the base 80 is also made of stainless steel, or the similar metal from which the channel 40 is made.

Generally, the base support 70 and the base 80 may be pre-fixed with channel 40 before installing the whole system on the roof. A person of ordinary skill in the art will understand that the assembly can be made at the time of installation of the system on the roof. In such circumstance, the base support 70, which is pre-fixed on the channel 40, is fixed on the roof after adjusting it according to the angle of roof or roof pitch. Once fixed, the base 80 is then inserted from the top of the channel and fixed on the roof. To secure the connection between the channel 40 and section 85, a cover collar 50 is inserted on to the channel 40 and towards the section 85. The collar 50 is tightened using bolt 65. Generally, the collar 50 is pre-made as one piece with the channel 40. A person of ordinary skill in the art will appreciate that the collar 50 can be made separately from the channel 40. Due to the flexibility of the section 85, the channel 40 can also be rotated around its axis. The longitudinal angle of the channel is then adjusted according to the shape of the end pipe of the chimney system that the channel spans. Once the channel is aligned with the end pipe of the chimney system, in the preferred embodiment, it is then stabilized with the end pipe using bolts 60. Typically, the bolts are made of stainless steel. The channel 40 is made with at least three bolts holes along its span at approximately half way along its perpendicular length. The bolts 60 are inserted and tightened inwardly towards the end pipe. The length of the bolts 60 is chosen according to the shape of the end pipe of the chimney system. It will be obvious to a person of ordinary skill in the art to use other means to stabilize the channel 40 with the end pipe 30. In another embodiment, a shown in FIG. 5, the channel 40 is stabilized with the end pipe 30 using spring thumbs 100. Upon stabilization of the channel 40, a crown top base 90 is placed on top of the channel. The crown base 90 is generally square shaped having a portion below the top similar to the shape of the channel but having a span smaller than the channel 40. This allows the crown top 90 to be placed inside the channel 40. For the easy passage of the gas, there are small holes along the span of the crown top.

FIG. 3 is the shows the exploded view of the present invention. In the preferred embodiment, the length of the base supports 70 is 10-12 inches long. The base support 70 has a raised column 70A approximately 6-8 inches in length. The raised column 70A has holes 70B through which the bolts 70C are inserted and tightened near the base of the channel 40. The dimension of section 85 is such that it completely covers raised column 70A of the base supports 70.

FIG. 4 shows the cross-section top view of the end pipe 30 longitudinally covered by the channel 40. The bolts 60 are tightened on to the wall of the end pipe. Similarly, FIG. 5 shows the cross-section top view of the end pipe 30 longitudinally covered by the channel 40. However, in FIG. 5, which is another embodiment, the channel is stabilized using spring thumbs 100 instead of using bolts.
