BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of attic storage systems and, more specifically, to a set of hardware that mounts to a pair of wood webs that are part of adjacent trusses located in the attic area between the ceiling and roof of a typical wood framed house. The set of hardware, once assembled and secured, forms a shelf that will hold a tote or other large storage container safely.

2. Description of Relevant Art

For many homeowners the ability to store household items that are bulky and only occasionally used can be a problem. Examples of these types of household items are holiday decorations, artificial Christmas trees and other similar seasonal items. Garages are often sized so that there is only limited room for the placement of shelving or cabinets for storage along the side and/or front walls if the owner plans to park their vehicle(s) in the garage. Due to the additional building costs, many homes do not feature basements which would provide sufficient storage space for such bulky items. As most homes are of frame construction and feature peaked roofs, they do have an attic area that is formed in the open space created by the trusses that support the sloped roof above the ceiling of the interior space of the home. This attic area is often used as the location of the home's HVAC system and as such is made to be accessible for service or repairs via a pull-down ladder or similar access method. With the existence of both an attic space and a built-in access system, many homeowners choose to utilize this space as their primary storage area for such infrequently used items.

Patents of Sullivan, U.S. Pat. No. 7,389,614, Wainland, U.S. Pat. No. 8,096,087, Brandt et al., U.S. Pat. Nos. 9,435,113 and 9,732,522, and Mogck et al., U.S. Pat. No. 9,534,374, describe different mounting systems that allow for the area over or between the bottom chords of the trusses, that run horizontally across the bottom of the attic area, to be covered with plywood, or other similar solid sheeting, to form a floor that can be walked on and will allow items such as boxes, totes, crates, etc. to be laid out in a single layer or stacked, if the boxes, crates or totes facilitate stacking, on this floor for storage. While this does allow for storage it requires that either the items in storage be spread out to provide easy access to individual items or that open space be left in the attic to allow for the stacked items to be unstacked to select the specific box, crate or tote desired.

Patents of Balser, U.S. Pat. No. 7,591,105 and Dohrendorf, U.S. Pat. No. 7,878,317 describe a system of roller or skate wheel conveyors that are mounted on supports above the bottom chords of the trusses and have a series of boxes, crates or totes supported on them. These systems do not create a surface that can be walked on but do support the boxes, crates or totes holding items and allow them to be moved laterally across the bottom of the attic space to provide access.

Suess' U.S. Pat. No. 5,406,895 describes a trough-like shelf that is designed to have its width sit within and be mounted to the V-shape space formed between the edges of two adjacent webs within the structure of an individual truss and its length to run across, and be mounted to, the same location of two or more adjacent trusses. The shelf can either be a solid sheet of shaped material or constructed of a rigid mesh made from wires. The front and back edges will flex or pivot to align with the angle of incline of the edges of the two adjacent webs. This shelf can only be affixed in a specific location between the adjacent webs as the width of the bottom of the shelf will only fit in the place where the horizontal distance between the two adjacent webs is the same as the width of the flat bottom section of the shelf.

Oberhaus et al., U.S. Pat. No. 6,286,691, describes a rigid wire mesh single or multiple shelving system that is suspended from a set of hangers mounted to the top chords, or a combination of the top chords and webs, of a pair of trusses. The system can either be attached parallel to and between an adjacent pair of trusses or perpendicular to and across two or more trusses. If mounted parallel to and between adjacent trusses and to one side of the roof peak, then the slope of the roof would limit the length and/or number of shelves that could be fitted due to the reduced length of the down slope hanger. If mounted parallel between adjacent trusses but centered under the roof peak, the length and number of shelves that could be fitted would be improved, but by being placed in such a manner the shelves themselves could act as a partial or full barrier to safe passage down the length of the central open area formed between the inner pairs of webs of the series of trusses. If mounted perpendicular, the length and number of shelves that could be fitted would also be improved, but depending on the slope of the inner webs, which slope towards the peak of the roof, the shelves would either have to be mounted with a significant distance between the bottom shelf and the webs or have shelves removed above the point where the webs would intersect the backs of the shelves.

In view of the foregoing disadvantages and limitations found in the prior art for an attic storage system, there remains a need for an improved hardware device to provide for attic storage.

SUMMARY

The truss-mounted attic storage system described herein is a kit comprising a set of hardware components and a set of fasteners that are designed to be mounted on the exposed tension webs of the trusses in an attic of a typical frame-construction residence. By a kit, it is meant that the components provided are designed and adapted to be assembled in the intended location to provide a storage system as claimed. The system will generally attach to the tension webs of two adjacent trusses with the front or face of the system oriented towards the center open area of the attic. The system can be attached across a range of elevations from the point just above the location where the base of the tension web is attached to the bottom chord to a point near the spot where the top of the tension web attaches to the top chord. The option to be attached across a range of elevations allows for multiple storage systems to be attached at a desired spacing from the base to the top of the tension web. Once attached, the system creates two or more parallel linear support surfaces that will support a box, crate or tote and its contents.

The truss-mounted attic storage system comprises three types of shaped metal components that are designed and adapted to connect with each other and the truss components of a roof to form the storage system. The first metal component is the web-mountable bracket. The web-mountable bracket is designed in a U-shape or rectangular cross section so that it will attach to the edge and both sides of the 2×4 or 2×6 lumber tension web portion of the truss. The bracket is designed to be attached at a range of angles so that the face of the bracket is securely held in a vertical orientation, by a series of screw or nail fasteners, while the tension web it is attached to is sloped at an angle, typically vertical to 45 degrees from vertical, from the top chord near the roof peak down to the point where it is attached to the bottom chord. The basic system generally uses two of the web-mountable brackets that are attached to the tension webs of two adjacent trusses at the same elevation on the adjacent tension webs. (Once attached, they can be considered web-mounted brackets.) The face of the bracket is fitted on its lower edge with a U-shaped saddle that is designed to hold and securely support the second component of the system. The saddle is substantially perpendicular to the face of the bracket. In the preceding section the term securely is used to mean that the structural strength of the bracket and the holding and shear strength of the fasteners attaching the bracket to the tension web are such that a load greater than about 200 pounds can be safely supported.

The second component of the truss-mounted attic storage system is the cross bar. The cross bar is a rectangular cross-sectional shaped metal tube that has a series of spaced holes drilled or punched down the lengths of the top and bottom surfaces of the cross bar. The cross bar could be made with a U-shaped cross section, open edge towards the bottom, in place of the rectangular shape depicted in the figures. For the basic system the cross bar, with one of the surfaces with holes oriented upward, is placed between and into the saddles of two web-mounted brackets and is held at both ends by these saddles of the two web-mounted brackets. A carriage bolt or screw that passes through the aligned holes in the face of the saddle and face of the bracket is then inserted and tightened so that the saddles of both brackets clamp down on the ends of the cross bar to secure it in place. Once the cross bar is secured, the third and final component of the system can be attached.

The third component of the system is a set of at least two load support bars. The load support bars are U-shaped, with notches cut into the sides that allow the bar to have a close tolerance fit over the cross bar. The load support bars have a hole drilled or punched and countersunk into the top face of the load support bar at the location of the notch. For attachment, the load support bar notch is placed substantially perpendicular over the cross bar at the location of one of the holes in the top of the cross bar. The cross bar is then set into the notch in the load support bar and the load support bar lowered until the cross bar is fully seated into the notch in the load support bar. A flat head sheet metal screw or carriage bolt is then inserted through the hole in the load support bar and driven into the hole, or through the holes in the case of the carriage bolt, in the cross bar to secure them together. For the basic system, two load support bars are attached to the cross bar in this manner to form a pair of parallel supports for the crate, box or tote that will be placed on them.

Once assembled and mounted to a pair of adjacent tension webs, the system is ready to have the desired items packed up and placed on the load support bars for easily accessible storage by the homeowner.

Alternative configurations of the system include, but are not limited to, the following variations:

• • 1. Attaching the two web-mounted brackets not on adjacent trusses but with one or more trusses between them and using a cross bar long enough to bridge the longer span created between them. Then a sufficient number of load support bar pairings are attached to produce a system that will hold multiple crates, boxes or totes.
  • 2. Attaching three or more load support bars to the cross bar so that narrower crates, boxes or totes can be well supported.
  • 3. Attaching three or more web-mounted brackets to the tension webs of three or more adjacent trusses and inserting a cross bar between each pairing so that the ends of the adjacent cross bars share and are held and secured by the web-mounted bracket. Then, in turn two or more load support bars can be mounted to each cross bar.

The described truss-mounted attic storage system can be easily installed using basic hand tools (e.g., level, pencil, screwdriver and pliers) and is designed to be assembled in more than one configuration and/or at a range of elevations so that the user can adapt the system to meet their specific needs. The pieces as described can be made by cutting or punching and bending or stamping sheet metal. Although discussed in terms of a preferred embodiment of metal components, these components could also be made by molding or casting them from metal or molding and/or extruding them in other materials such as fiber reinforced thermoplastics. As a result, the known deficiencies of the current attic storage devices are overcome. While the kits described above can be packaged and marketed to do-it-yourself homeowners, they could also be sold to housing remodeling contractors and builders, perhaps at wholesale for the latter.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

In general, the following description adopts a terrestrial frame of reference, in which the bottom of a component is considered to be the side nearest the floor or earth when in normal use, and the top being the side opposite and facing upward. The term “face” is used to identify the portion that is in closest proximity to the peak of the roof. The term “back” is used to identify the reverse portion that is oriented towards the exterior wall of the house. The term “and/or” is used in the conventional sense, in which “A and/or B” indicates that A or B, or both, may be present. Where dimensions or angles are given, they are approximate rather than precise, as required to fit a variety of attic installations. Similarly, when one component is “substantially” perpendicular to another, the angle between them can be slightly more or less than 90 degrees.

With reference to FIG. 1, the assembled truss-mounted attic storage system (2) is shown with two web-mounted brackets (4) holding both ends of the cross bar (6) and two load support bars (8) attached to the cross bar (6). For clarity, the holes for the various fasteners used are shown but not the fasteners themselves. This is the simplest embodiment, using two brackets (4), one cross bar (6) and two load support bars (8).

With reference to FIG. 2, a side view of a typical wooden roof truss (40) is shown. The basic form of the truss (40) is created by the triangle formed between the horizontal bottom chord (42) and the two inclined top chords (44). The bottom chord (42) provides the load bearing structure to which the panels used to form the ceiling of the living space below are attached to the bottom edge and safely suspended. The top chords (44) are the load bearing members that have panels attached to their outer edges and in turn have the shingles or other roofing materials attached to them to form the roof of the house. To ensure that the truss (40) is capable of both safely supporting the weights of the ceiling and roofing and to endure potential wind and snow loads from storms, a series of tension webs (46) and compression webs (48) are secured between the bottom chord (42) and each of the top chords (44). This naming convention used is based on “anatomy of a truss” by Fink, which was accessed from URL www.localarchitectsdirect.co.uk, and represents the prior art or typical structural components found in an attic.

With reference to FIG. 3, the web-mountable bracket (4) is shown. The web mountable bracket (4) features a hole (12) in the upper edge of the bracket face (10) that allows for a screw to be inserted and driven into the face of the tension web (not shown) to initially hold the web-mounted bracket (4) in place. If the tension web (not shown) is sloped, then a carriage bolt (not shown) is inserted from the back side of the bracket face (10) through the square hole (14) and then through the hole (20) in the saddle face (18) of the saddle (16). The nut (not shown) would then be loosely attached to the end of the carriage bolt (not shown). If the tension web (not shown) is oriented vertically, then no carriage bolt is inserted. The web-mountable bracket (4) is then pivoted so that the bracket face (10) is vertical. If necessary, the screw (not shown) already driven through the hole (12) in the bracket face (10) can be loosened to allow the web-mounted bracket (4) to pivot. Once vertical, screws (not shown) are driven through the holes (24) located in both bracket sides (22) that overlap the sides of the tension web (not shown) to secure it in the correct alignment. Once both of the web-mounted brackets (4) are secured, the cross bar (not shown) is placed so that the ends rest in the saddle (16) and then the cross bar (not shown here; see FIG. 1) is secured by either tightening the nut (not shown) on the previously inserted carriage bolt (not shown) or by inserting a screw (not shown) through the hole (20) and square hole (14) and driving it into the vertical tension web (not shown). The saddle (16) is substantially perpendicular to the bracket face (10) of the bracket (4).

With reference to FIGS. 4A and 4B, the cross bar (6) is shown. The cross bar (6) as depicted is a rectangular metal tube but could instead be U-shaped, with the open edge oriented down, and still perform its function. The top face (26) and bottom face (28) of the cross bar (6) have a series of holes (30) punched or drilled into them so that they align with each other. The minimum length of the cross bar (6) will typically be about 16 or 24 inches in length (the typical spacing between roof trusses) but could be made in any range of lengths as needed. The spacing of the holes (30) will be from about 2 to 6 inches across the top face (26) and bottom face (28) so that the spacing between the pair of load support bars (not shown) can be adjusted to provide a range of spacing options.

With reference to FIGS. 5A, 5B and 5C, the load support bar (8) is shown. The load support bar (8) is depicted as U-shaped but could instead be a rectangular or square tube shape and still perform its function. Both sides of the load support bar (8), and bottom as well if rectangular or square tube shaped, have a notch (32) cut into them that is sized to fit closely over the cross bar (not shown). The top surface of the load support bar (8) has a round hole (34) drilled or punched and countersunk above the midpoint of the notch (32). The load support bar (8) is attached to the cross bar (not shown) by aligning the notch (32) with the cross bar (not shown) at a location of one of the holes in the cross bar (not shown). Once aligned and seated over the cross bar (not shown) a flat head sheet metal screw is driven through the hole (34) into the hole in the cross bar (not shown) to attach it. If a carriage bolt is used as the fastener, then the hole (34) would be square shaped and not countersunk.

In the foregoing description, certain terms have been used for brevity, clarity and understanding. All equivalent relationships to those illustrated in the drawings and described in the preferred embodiment are to be encompassed by this present invention to produce the intended results. It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
