Description

FIELD OF THE INVENTION

This invention relates to a method and system of mounting a very early warning and aspirating smoke detection (VESDA) system.

BACKGROUND OF THE INVENTION

Aspirated particle or gas detection systems incorporate a sampling pipe or duct network consisting of one or more sampling pipes or tubes with one or more sampling inlets to collect air samples from various regions being monitored. Air is drawn in through the sampling inlets and through a particle detector and/or gas analyzer at a remote location. In order for the system to effectively monitor the surrounding atmosphere, the sampling tubes must remain free of impediments or blockages. Examples of such VESDA systems are seen in Cole, U.S. Pat. No. 7,738,098, Brooks, Jr., U.S. Pat. No. 5,896,088, and Williamson, U.S. Pat. Nos. 9,618,440 and 9,235,970.

In the past, in order to prevent blockages, the sampling tubes required periodic maintenance, which was labor and cost intensive due to the delicate nature of the tubing and the location of the tubes, often in hard to reach areas. Over the years, several patent applications have been filed that attempt to resolve the difficulties associated with maintaining the sampling tubes. These systems, Williamson, U.S. patent application Ser. No. 15/117,810, and Joseph, U.S. patent application Ser. No. 15/045,468 help to resolve the clogging issues, but are difficult to install and not aesthetically pleasing, as they extend noticeably beyond the surface area surrounding the sampling tube.

VESDA systems rely on air sample inlets that draw air into a particle detector through a pipe type network. These air sample inlets are typically tubular in nature, visible and potentially blocked by construction or other materials during or after installation. VESDA systems are significantly more expensive than individually mounted smoke detector devices due to the nature of the design and detection levels. The VESDA systems attempt to hide within the underlying structure for a more aesthetically pleasing appearance. Cultural, heritage buildings and sites as well as high profile dwellings that require unique fire solutions because of their design, function and age are significant users of VESDA systems. Because of the cultural significance and expensive nature of these support structures, it is highly desired to have a minimally invasive installation and natural appearance at each sampling tube location.

The disclosed invention provides a method and system of mounting a VESDA system within a support structure that simplifies installation, prevents obstruction and is aesthetically pleasing. The present invention provides an easy to install, cost effective solution that restricts obstructions of the sampling tubes, thereby forming a novel and complete solution to the difficulties associated with the prior art. The significant difference between the present invention and the prior art is the use of an easy to install device that protects the sampling tube from exposure and obstructions, while blending into the underlying structural aesthetic. Further, the present invention is installed using common, readily available construction materials such as spackle or joint compound and does not require any specialized tools.

The present invention provides a flange device having a tapeable edge compatible with a VESDA sampling tube system. The flange is affixed to the support structure, interconnected with the VESDA tubing system, and then camouflaged with spackle or similar material that blends into the existing support structure. Once installation is complete, only a small aperture in the support structure is visible.

The present invention provides a complete solution that resolves the prior art issues of remote sampling tube obstructions and aesthetically pleasing installation. Benefits of this novel invention are easily seen in novel building designs requiring unique solutions.

DETAILED DESCRIPTION OF THE INVENTION

In the embodiment described herein, the present invention provides for a system and method of mounting a VESDA system in a structure to create an aesthetically pleasing finish that prevents sampling tube obstruction. The unique design combines a flange design with the sampling tube VESDA system. This cost effective novel invention provides ease of installation and obstruction prevention combined with common, readily available finishing products to create a camouflaged surface that blends with the existing structural surface.

Before proceeding to the detailed description, the following definition relates to the present invention. VESDA is defined as a very early warning aspirating smoke detection solution that provides continuous air sampling and warns of an impending fire hazard. VESDA is manufactured by Xtralis Pty Ltd. For the purposes of this application, VESDA is further defined to include similar systems manufactured by Xtralis or others that include a sampling tube and/or particle collection arrangement.

The description which follows is of the first embodiment of the method and system of mounting a VESDA system within a support structure of this invention. Referring now to FIGS. 1 through 5, the first embodiment of the flange insert device is generally referred to by the number 10. As set forth in FIG. 4, the flange insert device 11 is typically embedded within the support structure 12 and camouflaged through the use of joint compound, spackle or similar substance 14 to match the existing structure surface 12. The support structure 12, as discussed, is a sheetrock substance, however, any conventional support structure including plaster, wood, metal, stone and the like forms a part of the invention.

The flange insert device 11 is comprised of a base section 16. The base section 16 is shown as circular in nature, however variations include oval, square, rectangular or similar shaped sections. In one of the circular form embodiment, the base section 16 is approximately 2 inches in diameter. The base section 16 is adjacent to an extension 18 having an aperture 20 therethrough to accept the VESDA sampling tube 22 and an outer diameter of approximately 5/16 of an inch. In one embodiment of the invention the extension 18 is formed having substantially cylindrical configuration. The extension 18 optionally includes a slightly tapered end (not shown). The extension 18 is configured to be inserted within the VESDA system components 38.

As best illustrated in FIGS. 1 and 4 the aperture 20 passes through the extension 18, including the base 16. The base section 16 optionally contains extensions 24, extending inwardly within the aperture 20, to ensure that the sampling tube 22 does not extend to the exterior surface 34, and does not exceed the exterior surface 26 of the support structure 12. The cylindrical extension 18 contains optional threading 28 to assist in securely installing the flange insert device 11 within the support structure 12 and the VESDA system components 38. The flange insert device 11 is comprised of any material suitable for the support structure 12 including aluminum, steel, wood, plastics and similar.

In the illustrated embodiment of the flange insert device 11 base section 16 is approximately 1/16 of an inch in thickness and is either uniformly thick (See FIG. 1) or contains a tapered edge 42 (See FIG. 8). Other configurations and dimensions of the base section are within the scope of the invention. The base section 16 has at least 2 two apertures 48 therethrough for receipt of fastening devices 31. Each aperture 48 is approximately inch in diameter. The base section 16 has an exterior surface 34 and an interior surface 36 and is installed within the support structure 12 through an aperture 30 in the support structure 12 of approximately 1 inch in diameter. The flange insert device 11 is secured within and affixed to the support structure 12 through the use of fastening devices 31 such as screws or nails (generally 2 to 4 fastening devices 31) or through the use of any conventional adhesive substance associated with the interior surface 36 (not shown).

The exterior surface 34 includes a raised flange section or lip 46 that surrounds outer or distal end of the aperture 20. In one embodiment the lip 46 extends approximately 1/8 of an inch from the exterior surface 34. The raised flange section 46 is critical to prevent obstructions from entering the sampling tube 22. Furthermore, upon installation the lip 46 is designed to accept a predetermined amount (1/8 of an inch, for example) of a camouflaging substance 14 such as joint compound, spackle or similar. As illustrated in FIG. 4, in the installed condition, an exterior surface of the substance 14 is in flash with or does not extend beyond an outer edge of the lip 46. The exterior surface 34 contains ribbing 40 to assist with the adherence of the camouflaging substance 14. In the illustrated embodiment, the ribbing 40 takes the form of linear indentations, random or patterned indentations, or nodules (not shown). Other forms of ribbing are also contemplated. When the base section is installed, and the camouflaging substance 14 applied, such base section combination is smoothly transferred into the exterior surface 26 of the support structure or is in flash with the exterior surface of the support structure. This arrangement substantially improving appearance of the outer area of the VESDA system.

The flange insert device 11 is configured to be installed within the VESDA system components 38. The threaded interconnection component 28 is compatible with the VESDA system components and secured therewithin.

The description which follows is of a second embodiment of the method and system of mounting a VESDA system within a support structure. For ease of comprehension, where similar parts are shown, reference designators "100" units higher than those previously employed are used. Thus, the flange insert device 111 of the second embodiment is analogous to the flange insert device 11 of the first embodiment. Referring now to FIGS. 6 to 8 the second embodiment of the method and system of mounting a VESDA system within the support structure is shown and is referred to generally by the numeral 110.

The prior art relating to the present invention is shown in FIG. 6 and represented by numeral 150. As seen in the prior art VESDA system 150, the system exceeds the surface structure 112. This exceedance is visible and aesthetically displeasing. In historically and artistically significant structures, a high importance is placed on visible appearance and safety. The VESDA system in conjunction with the present invention resolves the safety and aesthetic issues in such structures.

As shown in FIG. 7, the system 110 of present invention is camouflaged within and against the support structure 112. The flange insert device 111 is shown embedded within the support structure 112 and camouflaged through the use of joint compound, spackle or similar substance 114 to match the existing structure surface. The support structure 112 is shown as a sheetrock substance, however, any number of surfaces including plaster, wood, metal, stone and similar are included.

The flange insert device 111 is comprised of a base section 116. The base section 116 is shown as circular in nature, however variations include oval, square, rectangular or similar shaped sections. In circular form, the base section 116 is approximately 2 inches in diameter. As also illustrated in FIG. 8, the base section 116 is adjacent to an extension 118 having an aperture 120 therethrough to accept the VESDA sampling tube 122 therethrough. In one embodiment an outer diameter of the base section 116 is approximately 5/16 of an inch. The extension 118 optionally includes a slightly tapered end. The extension 118 is configured to be inserted within the VESDA system components 138.

Similar to the previously discussed embodiment (See FIG. 4), the base section 116 optionally contains extensions 24 to ensure that the sampling tube 122 does not exceed the exterior surface 126 of the support structure 112. The extension 118 contains optional threading 128 to assist in securely installing the flange insert device 111 into the support structure 112 and within the VESDA system components 138. The flange insert device 111 is comprised of any material suitable for the support structure 112 including aluminum, steel, wood, plastics and similar.

In one modification the flange insert device 111 base section 116 is approximately 1/16 of an inch in thickness and is either uniformly thick (See FIG. 1) or contains a tapered edge 142 (See FIG. 8). The base section 116 has at least 2 two apertures 148 therethrough for receipt of fastening devices 131. In the above discussed modification, each aperture 148 is approximately inch in diameter. The base section 116 has an exterior surface 134 and an interior surface 136 and is installed within the support structure 112 through the aperture in the support structure 112, which can be approximately 1 inch in diameter. The flange insert device 111 is secured within and affixed to the support structure 112 through the use of a fastening arrangement. As illustrated, the fastening arrangement can be in the form of fastening devices 131 such as screws or nails (generally 2 to 4 fastening devices 131) or through the use of an adhesive substance associated with the interior surface 136 (not shown).

The exterior surface 134 includes a raised flange section or lip 146, which can be circular in nature. In one embodiment the lip 146 extends approximately 1/8 of an inch from the exterior surface 134. The flange section is critical to preventing obstructions from entering the sampling tube 122. In one application the lip 146 is designed to accept 1/8 of an inch of a camouflaging substance 114 such as joint compound, spackle or similar. The exterior surface 134 contains ribbing 140 to assist with the adherence of the camouflaging substance 114 (See FIGS. 2, 3). In one of the embodiments, the ribbing 140 takes the form of linear indentations, random or patterned indentations, or nodules (not shown).

With respect to the embodiment of FIGS. 1-5, the method of installing the flange insert device 11 includes the following steps: cutting the aperture 30 in the support structure 12 (in the illustrated embodiment the aperture 30 can be an approximately 1 inch in diameter); inserting the flange device 11 within the support structure 12 through the aperture 30; positioning/threading the sampling tube 22 into the aperture 20 of the extension 38; securing the cylindrical extension 18 within the VESDA system components 38; affixing the flange insert device 11 to the support structure 12 through the use of fastening devices 31; camouflaging the flange insert device 11 with approximately 1/8 of an inch of a camouflaging substance 14 such as joint compound, spackle, or similar does not extend beyond the lip 46; and ensuring that the aperture 20 in the extension 38 is not obstructed, and also insuring that the exterior surface 34 of the base section 16 as well as the camouflaging substance is smoothly transferred into (or in flash with) the exterior surface 26 of the structure 12.

As to the embodiment of FIGS. 7 and 8, the method of installing the flange insert device 111 is similar to the above-discussed and includes the following steps: cutting the aperture 130 in the surface structure 112; inserting the flange insert device 111 within the surface structure 112; threading the sampling tube 122 into the cylindrical extension 138; securing the cylindrical extension 118 within the VESDA system components 138; affixing the flange insert device 111 to the surface structure 112 by any conventional means or through the use of fastening devices 131; camouflaging the flange insert device 111 with the camouflaging substance 114 such as joint compound, spackle, or similar, wherein the camouflaging substance 114 does not extend beyond the lip 146; and, ensuring that the aperture 120 in the cylindrical extension 138 is not obstructed, and also insuring that the exterior surface 134 of the base section as well as the camouflaging substance is smoothly transferred into (or is in flash with) the exterior surface of the structure 112.

The present system and method of installing the flange insert device 111 is economical and easy to install. Installation requires simple readily available tools and supplies and provides an aesthetically pleasing finish.

The disclosed invention provides a unique aesthetically-pleasing solution to installing and camouflaging a VESDA system within a support structure.
