Embodiments disclosed herein are generally related to an electrical box mounting bracket and more particularly to a method and apparatus for mounting an electrical box in a cinder block or other similar type wall with an electrical box block bracket with tabs.
During the process of installing an electrical box in a block wall, such as a cinder block wall, one contractor, typically an electrical contractor, has to hold an electrical box with mud ring and conduit in place while a second contractor, typically a block mason or brick layer, completes the task of installing the electrical box into the block wall. Because the positioning of the electrical box on the block wall during installation and it's instability, failure of a second contractor to hold the conventional electrical box in place while the block mason completes the installation task can result in the electrical box falling into an opening of the block wall and being lost and/or damaged. This typically means that the electrical contractor has to wait while block mason measures and cuts the opening for the electrical box into the block and then lays the block in place, which can take up to fifteen minutes, or more. Once the opening is cut into the block, and the block is brought back to the install location where the electrical contractor is waiting, the electrical contractor then has to hold the box and conduit in place while block mason places the block or blocks over the electrical box and backfills the area with cement. While the need for two contractors to complete this single task may not seem too burdensome, when considering that large-scale block construction can include hundreds of electrical boxes that need to be installed, the time and money that must be invested to simply hold an electrical box in place can become quite significant.
Another issue is that some items designed or configured to be mounted to an electrical box can require the use of the corner screw holes on the block bracket. Conventional block brackets do not include mounting holes used to mount an electrical box or other device to the block bracket. If an installer or contractor wants to install electrical box or other device a mud ring must be used in conjunction with the electrical box to hold it in place on the block bracket. Conventional block brackets are not capable of coupling to both an electrical box and another device, such as an alarm strobe because the conventional block bracket lacks mounting holes.
Reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
Exemplary embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments are shown. The concepts disclosed herein may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the concepts to those skilled in the art. Like numbers refer to like, but not necessarily the same or identical, elements throughout. Turning now to the drawings, in which like numerals indicate like elements throughout the figures, exemplary embodiments are described in detail. As would be recognized by a person of ordinary skill in the art having the benefit of the present disclosure, the claimed invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments depicted and described herein.
The present disclosure is directed to methods and apparatus for an electrical box block bracket. The exemplary electrical box block bracket can sit down in an open cell of a concrete block or other type of block building material to hold the electrical box in place for a brick mason to come along later and cut the covering block. This eliminates the need of the electrical contractor having to babysit the electrical box until the brick mason arrives or completes the measuring and cutting of the block for installation.
The electrical box block bracket can include a front face that includes an opening therethrough to receive an electrical junction box, such as a four-inch square electrical junction box or any other type of electrical junction box. The electrical box block bracket can have opposing top and bottom edges and opposing side edges. A first flexible panel can be coupled to and extend from the one of the side edges of the face plate. In one example the first adjustable panel can rotate about the longitudinal axis of the side edge. A second adjustable panel can be coupled to and extend from the opposing side edge of the face plate. Similar to the first adjustable panel, the second adjustable panel can rotate about the longitudinal axis of the opposing side edge. In one example embodiment, the axis of rotation for the first adjustable panel and the second adjustable panel are parallel to one another. Each of the first and second adjustable panels can be integrally formed with the face plate and can include a foldable tab disposed along the surface of the respective adjustable panel. The foldable tab is configured to extend out from the surface of the respective adjustable panel and contact a surface of a mounting block to provide additional stability to the rear portion of the electrical box coupled to the electrical box block bracket. The rear edge of each adjustable panel may also include a serrated edge extending along at least a portion of the rear edge. The serrated edge can be configured to contact an inner wall of an opening of a block, such as a cinder block, to created increased friction between the rear edge of the adjustable panel and the inner wall of the block to help hold the electrical box block bracket in place before the foldable tabs are folded over portions of the block.
Hereinafter, the electrical box block bracket will be described with reference to installation in/on a cinder block. However, the description of the electrical box block bracket being installed in a cinder block wall is for example purposes only as the electrical box block bracket can be used with many other types of block used to form block walls or other structures. As such, the description of the apparatus and methods with reference to a cinder block formation should not be so limited.
The face plate 105 can also include an electrical box aperture 120 that provides a passageway through the face plate 105 from the front side to the rear side. In certain example embodiments, the electrical box aperture 120 is sized and shaped to receive. at least partially therein, a mud ring and/or four inch by four inch square electrical junction box (e.g., a portion of the face plate is pinched or sandwiched between the mud ring and the electrical junction box to hold the electrical junction box to the electrical box block bracket). In one example embodiment, the electrical box aperture 120 is square or substantially square-shaped. Alternatively, the electrical box aperture 120 can have any other geometric or non-geometric shape including, but not limited to, round and rectangular. In certain example embodiments, the electrical box aperture 120 takes up at least half of the surface area of the face plate 105. Alternatively, the electrical box aperture 120 takes up anywhere between 20%-95% of the surface area of the face plate 105.
The electrical box block bracket can also include a first adjustable panel 110 and a second adjustable panel 115. In certain example embodiments, the first adjustable panel 110 is a planar or substantially planar member having an outer surface 111 and an opposing inner surface 112. The first adjustable panel 110 can be coupled to or integrally formed with the face plate 105 along the first side edge of the face plate 105. For example, the first adjustable panel 110 may be coupled to one portion of a hinge and the second portion of the hinge may be coupled to the face plate 105. Alternatively, the material used to make the first adjustable panel 110 and the face plate 105 may be such that it is flexible and or elastic or otherwise configured to cyclically move between multiple angles with respect to the rear surface of the face plate 105.
The first adjustable panel 110 can extend away from the back side of the face plate 105 in an orthogonal or substantially orthogonal direction from the planar surface of the face plate 105. In one example embodiment, the first adjustable panel 110 is made from the same material as the face plate 105 (e.g., sheet metal, steel, aluminum, another metal or metal alloy, or plastic). In certain example embodiments, the first adjustable panel 110 rotates about a vertical axis. The vertical axis can be defined by the connection segment (e.g., the first side edge of the face plate 105) between the first adjustable panel 110 and the face plate 105. In one example, the first adjustable panel 110 is capable of rotating in such a way as to generate an angle between the rear surface of the face plate 105 and the inner surface 112 of the first adjustable panel 110 of between 1-180 degrees.
The first adjustable panel 110 can also include or have coupled thereto an adjustable tab 130. The adjustable tab 130 can have a fixed end affixed to the first adjustable panel 110 and a free end 131 distally positioned from the fixed end. In one example embodiment, the adjustable tab 130 is integrally formed with the first adjustable panel 110. Alternatively, the fixed end of the adjustable tab 130 can be coupled to a portion of the first adjustable panel 110 (such as by screws, rivets, welding, adhesive, etc.). The adjustable tab 130 can have any geometric or non-geometric shape including, but not limited to, a rectangle. In certain example embodiments, the adjustable tab 130 is an elongated member having a length that is greater than or substantially greater than its width and is configured to bend along the fixed end at or near the line where the adjustable tab 130 intersects the remainder of the first adjustable panel 110 to extend out away from the outer surface 111 of the first adjustable panel 110. In one example embodiment, at least a portion of the adjustable tab 130, including the free end 131, may be adjusted from a first position, where the outer surface of the adjustable tab 130 is aligned or substantially aligned (parallel plane) with the outer surface 111 of the first adjustable panel 110, to a second position, where at least a portion of the adjustable tab 130 extends in a direction orthogonal to or substantially orthogonal to the outer surface 111 of the first adjustable panel 110. In certain example embodiments, at least a portion of the adjustable tab 130 may be further bent so as to extend downward from the orthogonally extending portion in an orthogonal or substantially orthogonal direction such that this further extending portion is extending in a direction that is substantially parallel to the outer surface 111 of the first adjustable panel 110.
The first adjustable panel 110 can also include a tab aperture 125. The tab aperture 125 provides an opening or passageway through the first adjustable panel 110 and also provides a way to access or otherwise grip the free end 131 of the adjustable tab 130. The example tab aperture may have any geometric or non-geometric shape. In one example embodiment, the width of the tab aperture 125 is the same or slightly greater than the width of the adjustable tab 130 and the length of the tab aperture 125 can be anywhere between slightly greater than the length of the adjustable tab 130 to significantly greater (e.g., on the order of twice as long) as the length of the adjustable tab 130.
The first adjustable panel 110 may also include one or more serrations 135 that together form a serrated edge 135. The serrations can be disposed along a free edge of the first adjustable panel 110 and can extend from the bottom of the free edge upward along all or a portion of the free edge. In one example embodiment, the serrated edge 135 may extend along only a portion of the free edge of the first adjustable panel 110 and is configured to engage or otherwise contact an inner surface of a cinder block to increase the friction between the first adjustable panel 110 and the inner surface of the cinder block and to limit rotational movement of the bracket 100 into the opening of the cinder block. The first adjustable panel 110 may also include a beveled edge 132 extending from the top edge of the first adjustable panel 110 to the free edge of the first adjustable panel 110. In one example embodiment, the beveled edge 132 is configured to allow another block to fit over the electrical box block bracket 100 without hitting the top edge of the first adjustable panel 110, which would occur if the edge 132 was not beveled. In certain example embodiments, the length of the beveled edge 132 is adjustable and can be increased by decreasing the length of the tab aperture 125.
In certain example embodiments, the second adjustable panel 115 is a planar or substantially planar member having an outer surface 111 and an opposing inner surface 112. The second adjustable panel 115 can be coupled to or integrally formed with the face plate 105 along the second side edge of the face plate 105. For example, the second adjustable panel 115 may be coupled to one portion of a hinge and the second portion of the hinge may be coupled to the second side edge of the face plate 105. Alternatively, the material used to make the second adjustable panel 115 and the face plate 105 may be such that it is flexible and or elastic or otherwise configured to cyclically move between multiple angles with respect to the rear surface of the face plate 105.
The second adjustable panel 115 can extend away from the back side of the face plate 105 in an orthogonal or substantially orthogonal direction from the planar surface of the face plate 105. In one example embodiment, the second adjustable panel 115 is made from the same material as the face plate 105 (e.g., sheet metal, steel, aluminum, another metal or metal alloy, or plastic). In one example embodiment, the face plate 105, first adjustable panel 110, second adjustable panel 115 and tabs 130 are integrally formed from a single piece of material (e.g., a single piece of sheet metal, steel, aluminum, another metal, a metal alloy, plastic, etc.). In certain example embodiments, the second adjustable panel 115 rotates about a vertical axis. The vertical axis can be defined by the connection segment (e.g., the second side edge of the face plate 105) between the second adjustable panel 115 and the face plate 105. In one example, the second adjustable panel 115 is capable of rotating in such a way as to generate an angle between the rear surface of the face plate 105 and the inner surface 112 of the second adjustable panel 115 of between 1-180 degrees. In one example embodiment, the axis of rotation of the first adjustable panel and the second adjustable panel are parallel.
The second adjustable panel 115 can also include or have coupled thereto an adjustable tab 130. The adjustable tab 130 can have a fixed end affixed to the second adjustable panel 115 and a free end 131 distally positioned from the fixed end. In one example embodiment, the adjustable tab 130 is integrally formed with the second adjustable panel 115. Alternatively, the fixed end of the adjustable tab 130 can be coupled to a portion of the second adjustable panel 110 (such as by screws, rivets, welding, adhesive, etc.). The adjustable tab 130 can have any geometric or non-geometric shape including, but not limited to, a rectangle. In certain example embodiments, the adjustable tab 130 is an elongated member having a length that is greater than or substantially greater than its width and is configured to bend along the fixed end at or near the line where the adjustable tab 130 intersects the remainder of the second adjustable panel 115 to extend out away from the outer surface 111 of the second adjustable panel 115. In one example embodiment, at least a portion of the adjustable tab 130, including the free end 131, may be adjusted from a first position, where the outer surface of the adjustable tab 130 is aligned or substantially aligned (parallel plane) with the outer surface 111 of the second adjustable panel 115, to a second position, where at least a portion of the adjustable tab 130 extends in a direction orthogonal to or substantially orthogonal to the outer surface 111 of the second adjustable panel 115. In certain example embodiments, at least a portion of the adjustable tab 130 may be further bent so as to extend downward from the orthogonally extending portion in an orthogonal or substantially orthogonal direction such that this further extending portion is extending in a direction that is substantially parallel to the outer surface 111 of the second adjustable panel 115. As such, the adjustable tab 130 can be of a length that the tab 130 only rests along the top surface of the rib, or side wall of a block, or alternatively may be of a longer length, such that a portion of the tab 130 rests on the top surface of the rib or side wall and another portion of the tab 130 is bent at an angle orthogonal or substantially orthogonal to the first portion to extend along a side surface (e.g., the vertical side surface) of a block (e.g., a cinder block 305).
The second adjustable panel 115 can also include a tab aperture 125. The tab aperture 125 provides an opening or passageway through the second adjustable panel 115 and also provides a way to access or otherwise grip the free end 131 of the adjustable tab 130. The example tab aperture 125 may have any geometric or non-geometric shape including, for example, a rectangular shape. In one example embodiment, the width of the tab aperture 125 is the same or slightly greater than the width of the adjustable tab 130 and the length of the tab aperture 125 can be anywhere between slightly greater than the length of the adjustable tab 130 to significantly greater (e.g., on the order of twice as long) as the length of the adjustable tab 130.
The second adjustable panel 115 may also include one or more serrations 135 that together form a serrated edge 135. The serrations can be disposed along a free edge of the second adjustable panel 115 and can extend from the bottom of the free edge upward along all or a portion of the free edge. In one example embodiment, the serrated edge 135 may extend along only a portion of the free edge of the second adjustable panel 115 and is configured to engage or otherwise contact an inner surface of a cinder block to increase the friction between the second adjustable panel 115 and the inner surface of the cinder block and to limit rotational movement of the bracket 100 into the opening of the cinder block. The second adjustable panel 115 may also include a beveled edge 132 extending from the top edge of the second adjustable panel 115 to the free edge of the second adjustable panel 115. In one example embodiment, the beveled edge 132 is configured to allow another block to fit over the electrical box block bracket 100 without hitting the top edge of the second adjustable panel 115, which would occur if the edge 132 was not beveled. In certain example embodiments, the length of the beveled edge 132 is adjustable and can be increased by decreasing the length of the tab aperture 125. In certain example embodiments, the exemplary bracket 100 may not include the serrated edges 135 on either or both of the adjustable panels 110, 115.
Each screw tab 205-220 may include a screw aperture 225. The screw aperture 225 may be a through-hole or may be threaded in certain example embodiments. The example screw aperture 225 has a generally circular shape and provides a passageway through the respective screw tab 205-220. In certain example embodiments, the four screw apertures 225 are provided to allow for the optional capability of installing and/or attaching fire alarm strobes and/or other devices to the electrical box block bracket 200. In certain examples, fire alarm strobes are coupled to the block bracket along with a four or more-sided enclosure or box, such that two screw apertures 225 (e.g., two apertures 225 disposed diagonally from one-another) are used to receive two screws therethrough to mount the fire alarm strobe to the face plate 105 of the block bracket 200. As such, by including four screw apertures 225 in the electrical box block bracket 200, two of the screw apertures 225 (e.g., two apertures 225 disposed diagonally from one-another) can be used to attach a four-sided square/rectangular junction box or enclosure to the electrical box block bracket 200 and the other two screw apertures 225 (e.g., two other apertures disposed diagonally from one-another) can be used to attach the fire alarm strobe to the electrical box block bracket 200.
