System and method for roof repair
A method and special tool system for cleaning around the damaged areas of a rubber roof of a building structure. The method utilizes an elongated tool of about four feet in length and having a rotating output shaft positioned at a lower end thereof. A brush structure is attached to the elongated tool by means of a specially designed adapter element. The method and system greatly reduces the time needed to repair a roof which has been damaged, for example, by a lightning strike or other destructive force. The roof patching job is thus much easier and more efficient for the repairing personnel.
The present invention is generally related to the building repair and tool arts and, in particular, to a system and method for repairing a damaged roof of a building.
As rubber has become more common as a roofing material, the need to be able to repair a damaged rubber roof has become apparent to those of skill in the roofing and tool arts.
Serious damage requiring immediate repair can be caused, for example, by a lightning strike upon the roof of a building.
Accordingly, it is an object of the present invention to demonstrate a novel method for repairing the damaged roof of a building.
It is a further object to set forth a special tool design which enables a surface such as a rubber roof of a building to be efficiently and quickly repaired even under bad weather conditions.
It is also an object of the invention to show a modified tool design which can be economically mass produced for widespread commercial appeal in the tool production arts.
It is a further object to render a repair job easier to perform by repairing personnel which is of great advantage especially in cold and windy conditions.
These and other objects and advantages of the invention will be apparent to those of skill in the roofing repair and tool design arts.
PRIOR ART PATENTS AND DESIGNSThe invention method is related to the building roof arts found in U.S. Patent and Trademark Office Class 52.
Other related Patents found in a full search of the prior art are as follows:
- U.S. Pat. No. 5,522,162 issued to Allison in 1996 for a snow blower design having a special structure to take in and discharge snow,
- U.S. Pat. No. 5,697,453 issued to Van Den Bosch in 1997 for a cutting tool with multiple blade designs.
The present invention is believed to be clearly patentable over the above and all other systems and methods in the prior art.
SUMMARY OF THE INVENTIONRoofing repair and treatment is effected using a specially designed cleaning tool.
The tool is elongated so that workmen repairing a damaged roof need not do the required cleaning on hands and knees.
The method and system are especially effective for rubber roofs which may have been damaged, for example, by a lightning strike.
The tool structure includes a motorized drive means of about four feet in length and a specially designed adapter and brush element.
Since the rubber roof must be thoroughly cleaned before patching a damaged area, the total repair time is greatly reduced. The safety of working repair personnel is increased since the damaged area need not be approached so closely. The time required for repair workmen to be out in cold weather is also greatly reduced.
BRIEF DESCRIPTION OF THE DRAWING FIGURES
Referring to the drawing figures,
Roof 12 in this example includes an upper gravel layer 14 and a rubber layer 15. Rubber layer 15 is made of reinforced rubber or rubber-plastic compounds of use in the construction arts.
As further shown in
Layers 14, 15, 16 and 17 are again shown with damage indicated to each layer.
The method of effecting repair of the damaged roof is indicated in
Referring to
In order to add a rubber patch layer 15a, the areas around the damaged portion 19 must be thoroughly scrubbed and cleaned. Such areas are indicated at numerals 19a, 19b, 19c and 19d. Such cleaning is typically done manually by repairmen and is a very time-consuming process.
After a thorough cleaning of areas 19a, 19b, 19c and 19d is performed, two-sided adhesive tape is applied to the rubber layer 15 as indicated at numerals 20, 21, 22 and 23. Subsequently, patching section 15a is applied as indicated by the arrows in
The previously shown gravel layer 14 is then repositioned over the patch section 15a.
In order to more efficiently clean the areas 19a through 19d, a specialized tool has been devised by applicant. The upper portion of such tool is shown in
Referring to
The tool 30 includes an upper drive motor 31 having an ignition 31a. A gasoline supply tank is indicated at numeral 32.
A connecting shaft 33 is shown as within the outer housing and as extending to a lower bearing element 34. It is to be understood that shaft 33 drives the lower metal output shaft 35.
Other elements of the tool 30 are handle elements 36 and 36a, throttle 37 and a throttle cable 37a. A guard 38 is indicated schematically at numeral 38.
As will be further described, the elongated nature of tool 30 allows a working repairman to reach the sections around a damaged area for clean-purposes without having to get too close to the area.
Referring to
A specially designed adapter unit is indicated at numeral 40.
Adapter 40 has an upper section 41 and a lower section 43.
Upper section 41 has internal threads as shown at 42. Such are sized and shaped so as to be attachable to the threads 35a of the output shaft 35.
The adapter lower section 43 has external threads indicated at numeral 44.
The external threads 44 are sized and shaped so as to fit with the thread elements of a brush unit 50 to be further described.
Referring to
An opening 53 is formed in the upper brush layer and such is internally threaded as indicated at the drawing numeral 55.
The lower brush layer is shown at numeral 57 as having bristles 58 extending therefrom.
The brush structure 50 includes an open area as shown at numeral 59.
It is to be understood that the internal thread elements 55 are sized and shaped so as to mate with the external threads 44 of the adapter 40 which was previously described.
The overall brush structure is of a very light-weight and durable plastics material as utilized in the manufacturing arts. Further details of the brush structure are indicated in
Referring to
The bristles 58 are arranged in a spiral pattern as indicated at 61. Such is useful when the brush is used to clean and scrub a damaged area.
The use of a wetting agent such as water as a part of the treatment method is indicated by the letter W in block 62 of
In the example shown, the diameter of the brush structure is about four inches. The diameter of the open area 59 is approximately 2.4 inches. Such dimensions have been found to be critical for the particular roof cleaning and repair method described herein.
While a particular method and structure have been shown and described, it is intended in this specification to cover all equivalent structures and methods which would reasonably occur to those of skill in the art. The invention is further defined by the claims included.
