Guarded construction

Abstract

A temporary cover is provided for protecting the contents of electrical boxes during wall construction. The box can include the cover as a temporary attachment that bends into place and is torn away when finished. The cover can also be a stand-alone component that press fits into the box and has means for removal from the box, such as a tab on one side, or an aperture sized to receive at least a finger. The cover can also have a fin to engage with slot rails within the electrical box. Constructing a wall includes mounting the box within the wall, adding wiring within the box, covering the box with the temporary cover, finishing the wall, then removing the cover and replacing it with the permanent box cover.

Description

BACKGROUND

Field of the Invention

The invention is the field of construction.

Related Art

Building construction often involves the installation of components within a wall, e.g., ventilation and electrical boxes, prior to installation of drywall. Damage to these interior components can occur during drywall installation.

SUMMARY

Various embodiments of the invention include systems and methods of protecting electrical and other types of boxes and wires from construction processes including drywall routing, plastering and painting. For example, a temporary cover is used to protect electrical boxes and wires from damage by drywall routers. These temporary covers also keep plaster and paint away from the inside of the electrical box and wires. The temporary cover is installed by press fitting it into the electrical box after wiring is installed. As the temporary cover fits within the electrical box, it does not obstruct installation of drywall and is held in place by friction. The temporary cover optionally has a tab that can be grasped to remove the temporary cover from the electrical box after dry wall installation, routing, plaster and painting is completed.

DETAILED DESCRIPTION

FIG. 1 illustrates a top view of a temporary cover 110, according to various embodiments of the invention, while FIG. 2 shows a side view the same. The illustrated relative dimensions are not meant to be to scale. The temporary cover 110 is generally flat, thin, and shaped to fit snuggly within a standard size electrical box, or other in-wall component. The temporary cover 110 serves to protect wiring in the electrical box from damage due to cutting devices such as routers and saws, used in wall construction. Standard electrical box sizes include single gang, double gang, triple gang and quadruple gang. FIG. 1 shows a single gang embodiment, while FIG. 3 shows a top view of a double gang embodiment. The side view of the embodiment of FIG. 3 is the same as the one shown in FIG. 2. A triple gang embodiment is illustrated in the priority provisional application 62/576,580 and quadruple gang embodiments can be readily extrapolated from the prior examples.

In these embodiments, the temporary cover 110 also includes a tab 115 projecting from one side thereof to allow the temporary cover 110 to be removed easily. The temporary cover 110 and tab 115 can be constructed, for example, of cardboard, plastic, corrugated plastic, Bakelite, foam, rubber, cloth, paper, metal, and/or the like. Ideally, the material is hard enough to prevent or reduce saw blade penetration and ridged enough to be held inside the box by the friction between the temporary cover and the inside of the box. The temporary cover 110 is optionally flexible to better allow for a press-fit into the electrical box and to allow for slight variation in box size and shape. Tab 115 can be located in a variety of alternative locations, such as centrally located, as illustrated. While one tab 115 is illustrated, more than one can be implemented for larger temporary covers 110. The temporary cover 110 can also include recesses 120 sized and positioned to accommodate the screws of the electrical box used to connect the external cover after the wall is completed.

FIG. 4 illustrates a top view of a single gang temporary cover 410, according to various embodiments of the invention. In these embodiments the temporary cover 410 includes a tab 415 that is formed by cutting into the temporary cover 410 to create the tab 415 such that the tab 415 rotates around a fold line 425. Cardboard is an example of a suitable material for temporary cover 410. One advantage of this embodiment is that temporary covers 410 stack flat for shipping.

FIG. 5 illustrates a top view of a single gang temporary cover 510, according to various embodiments of the invention. In these embodiments the temporary cover 510 includes an aperture 530 disposed therethrough, in place of a tab Like the previous embodiments, covers 510 stack flat for shipping. The aperture 530 is sized so that at least a finger or small tool can be easily inserted therethrough. While the aperture 530 illustrated in FIG. 5 is round, other shapes can be used.

FIGS. 6 and 7 show side and front views, respectively, of an electrical box 600 having an open side 605 and a detachable temporary cover 610. The temporary cover 610 attaches to the electrical box 600 along a hinge 635. The hinge 635 can be perforated, for example, to allow the temporary cover 610 to be removed after use by tearing along the perforation. As illustrated in FIG. 6, the temporary cover 610 is rotated around the hinge 635 into place over the open side 605 to protect the interior of the electrical box 600.

FIG. 8 illustrates an exploded view of a double gang electrical box 800 and a double gang temporary cover 810 for the box 800. FIG. 9 shows a top view of the temporary cover 810. The temporary cover 810, in this embodiment, includes a tab 115 and a fin 840. The fin 840 is disposed on the side opposite the fin 115 and engages with slot rails 845 inside of the electrical box 800. A screw (not shown) optionally installs along line 850; the other lines for screws have been omitted for clarity.

FIG. 10 illustrates a method of construction, according to various embodiments of the invention.

In an install box step 1010 an electrical box is installed in an unfinished wall, such as by attachment to a stud within the wall. The electrical box can be of a type for containing wires for a switch, low voltage audio controls, a light fixture, an electrical plug outlet, etc. An unfinished wall, as used herein, means a wall still under construction and missing at least one of drywall, necessary routing, plaster, or paint.

In a wiring step 1020 one or more wires disposed within the wall are added to the electrical box. As used herein, “wiring” will be broadly understood to include each of electrical wiring, optical cables, and pneumatic tubes.

In a place cover step 1030 a temporary cover is placed over an open side of the electrical box, the temporary cover being sized to fit the open side. Step 1030 can include press fitting the temporary cover into the open side of the electrical box, and in some of these embodiments the temporary cover is pushed into the electrical box until the temporary cover is well recessed within the box at the completion of the step. In other embodiments, step 1030 can include folding or bending the temporary cover along a common hinge with the electrical box. In still other embodiments, the temporary cover includes a fin projecting from a side of the temporary cover, the interior of the electrical box includes slot rails, and step 1030 includes engaging the fin with the slot rails. Additionally, in some embodiments step 1030 includes securing the temporary cover to the electrical box using the box's existing screws and screw receptacles.

In a finish wall step 1040 the wall is finished. This step includes at least one of adding drywall to the wall, routing, plastering and painting the wall.

In a removal step 1050 the temporary cover is removed from the electrical box. For example, the temporary cover can be grasped by a tab, or one can insert a finger or tool into an aperture through the temporary cover in order to pull the temporary cover out from the electrical box. In other embodiments, step 1050 includes removing one or more screws used to secure the temporary cover to the electrical box. Step 1050 can also comprise tearing away the temporary cover from the electrical box along a hinge, such as by tearing along a line of perforations. Such a common connection between the temporary cover and the electrical box can be broken in other ways, such as by fatiguing the hinge, where the box and cover are both made from a metal.

In an external cover step 1060 an external cover, such as electrical outlet wall plate configured to be secured to the electrical box, is secured to the electrical box, such as with the previously mentioned screws. Step 1060 can additionally include installing plugs, switches, controls and the like to wires in the electrical box before securing the external cover.
