DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Before explaining the disclosed embodiment of the present invention in detail it is to be understood that the invention is not limited in its application to the details of the particular arrangement shown, since the invention is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.
FIG. 1 shows a first embodiment of a brace 100 for use in a tri-level safety rail. A U-shaped lip 104 is designed to fit around a gutterboard, which is a horizontal bordering structure typically positioned near to a roofline of a structure such as a house. It is important that the lip 104 be strong, sturdy, and solidly fixable to the gutterboard, as the brace 100 must be able to withstand a significant amount of force exerted thereupon.
It is the purpose of the present invention that a group of braces 100 be combined in the aggregate to provide a type of safety fence or safety rail around the roof of a house or other structure. One common use for such an arrangement is during the installation, repair, or tear-down of a roof of a house, although this is but an example and the present invention should not be considered as limited exclusively thereto. A movable bracket 108 holds the bottom level of the safety rail. The bracket 108 can be affixed in position by finger-screws or other securing means (not shown in FIG. 1). Two fixed brackets 112 and 116 support the middle and top levels of the safety rails.
FIG. 2 shows more detail of the bottom end of the brace 100. A plurality of holes 204 are positioned within the lip 104 so as to provide strength and durability for attaching it to the gutterboard, or other portion of the structure requiring a safety rail. In FIG. 2, the movable bracket 108 has a securing means 216. At the opposite end of the bracket 108 exist holes 208 and 212 for securing a bottom rail within the bracket 108. These holes 208, 212 are also for the purpose of attaching a securing mechanism, and thus can be threaded. The bottom rail secured within the bracket 108 could for example by a 2×4, although the present invention should not be considered as limited exclusively thereto.
FIG. 3 is a view of the base of a brace 100 secured in place and attached to a gutterboard. The brace 100 differs from that shown in FIGS. 1 and 2 in that the support brackets of FIG. 3 face toward the roof. In FIGS. 1 and 2, it is apparent that the support brackets 104,112, and 116 would, when installed, face away from the roof. The brace 100 of FIG. 3, as with those in FIGS. 1 and 2, is attached to the gutterboard via a variety of nails or screws located in holes 308 which penetrate through the lip 104. A securing means 216 holds the body of the brace 100 securely in place.
FIG. 4 is another view of the base of the brace 100 from FIG. 3. In FIG. 4 it is apparent that there can be multiple holes 308 within the lip 104. Indeed, the more holes 308, and more securing mechanisms passing therethrough such as nails or screws, the more solidly the lip 104 and therefore the entire brace 100 will hold to the gutterboard. However, an increase in the number of holes and securing mechanisms used will also increase the time necessary to install (and later remove) the brace 100.
The brace 100 can have a securing weld 312 or other solidifying means at its base. This is because it is so important that the lip 104 and body of the brace 100 be very solidly attached. The main portions of the mechanical stress exerted on the brace 100 will exist largely at its base.
FIG. 5 again shows the base of a brace 100, in which a movable bracket 504 differs from the earlier movable bracket 208 in that the bracket 504 includes a cylindrical-shaped housing 512, for accommodating a pipe-shaped mechanism such as that used in chain-link fences. This is because, as stated, the present invention is intended to provide a type of safety fence or safety rail around the roof of a house or other structure.
FIG. 6 shows a brace 100 supporting three levels of safety rail 804, which in FIG. 6 are 2×4s, although the present invention should not be considered as limited exclusively thereto. FIG. 7 shows a pair of braces 100 attached to a gutterboard at a roofline, where the braces 100 are supporting cylindrical pipes which are acting as safety rails.
FIGS. 8 and 9 show perspective views of safety rails supported by the brace 100 of the present invention. In FIG. 19 it is apparent that both 2×4s as well as pipe-rails can co-exist within the present invention.
FIG. 10 shows another embodiment of the present invention. In the embodiment of FIGS. 1-9, the purpose of the device 100 is generally to install a new roof. In the embodiment shown in FIG. 10, the purpose of the brace 1000 is instead to tear off an existing roof for repair or replacement. In these circumstances, there may not be a gutterboard available, or it may be so badly deteriorated such that it is unreliable.
Use of the embodiment shown in FIG. 10 is accomplished as follows. A triangular device 1004 is attached to a roof beam which supports shingles which are to be torn off. The triangular device 1004, which is sometimes referred to as a roof-jack, is nailed into the beam using the three holes provided therein. The triangular device 1004 is carefully chosen so that its angles match with the pitch of the roof. Alternatively, the device 1004 can be adjustable in angle, so that that present invention could accommodate a variety of roof pitches.
Normally, the device 1004 exists to create a foot layer or walkway, in which boards (e.g. 2×6) are inserted as shown in FIG. 10, as a type of stepping beam or foot rail for the roofers to move about on the slanted roof surface with less difficulty. However, the present invention takes advantage of a different effect of attaching the device 1004, which is to create a vertical surface 1008. The brace 1000 is secured to this vertical surface 1008 via a slot or hollow securing mechanism 1012 in which the brace 1000 can be vertically inserted. Additionally, the exact positioning of the brace 1000 within the slot or securing mechanism 1012 can be fixed using a threaded securing mechanism 1016, similar to those used in the embodiment of FIGS. 1-9.
A third embodiment of the present invention exists, in which a brace can be used with masonry, bricks, walls, wall studs, or other non-roof vertical surfaces. In this embodiment, an attachment mechanism is securedly affixed to a wall or other surface. The attachment mechanism has extension members securedly joined thereto, where these members support a base receptacle for seating a brace, and also provide a walkway such as but not limited to 20 inches in width. This embodiment has the advantage of interchangeability of parts. The brace can be inserted into the receptacle, the triangular device, or even into a U-shaped lip 104. Using such interchangeable parts, a construction company can purchase a smaller amount of braces, and insert them in the walls as the walls are being completed but before the roof is begun. After the walls are completed, by making some simple adjustments, the same braces can be used on the roof as well. Thus, it is not necessary to purchase separate safety parts for the roof and also for the walls.
It is anticipated that various changes may be made in the arrangement and operation of the system of the present invention without departing from the spirit and scope of the invention, as defined by the following claims.
