Electrical box support
First Claim
1. A mud box having an open end and a peripheral sidewall, a plurality of resilient spring legs attached to said box, said legs having free end portions engageable with one form surface for biasing said box in a direction to engage said box open end with an opposite form surface, said free end portions being spaced-apart a distance greater than the maximum distance across said peripheral sidewall so that the free end portions extend outwardly beyond the peripheral sidewall.

Abstract
An electrical box having spring legs for supporting the box within a space between a pair of spaced-apart parallel concrete forms. The legs engage the inside surface of one form and bias the open end of the box against the inside surface of the other form. The legs and the bottom of the box are cooperatively configured to facilitate attachment of the legs to the box. A bendable strap is attached to the box for wrapping around reinforcing bars within the forms. The legs and strap hold the box in position when concrete is poured into the space between the forms. The entire box and support elements remain embedded within the finished concrete wall, and with the open end of the box exposed at an outer surface of the concrete wall.

- 25. A support kit for attachment to an electrical mud box, said kit including a pair of generally U-shaped spring leg members, each spring leg member having a central attachment portion with an attachment opening therethrough, and each spring leg member having a pair of legs diverging outwardly from said attachment portion and terminating in leg end portions that are spaced-apart a distance greater than the length of said central attachment portion.
- 29. A mud box having an open end and a bottom wall opposite from said open end, said bottom wall having an external attachment projection, a plurality of abutments on said bottom wall spaced outwardly from said projection and forming abutment guideways therebetween, a plurality of resilient spring legs having attachment portions that are received in said abutment guideways and have attachment openings received over said attachment projection to attach said spring legs to said box, said spring legs having free end portions engageable with one form surface for biasing said box in a direction to engage said box open end with an opposite form surface.
-
31. A mud box having an open end, a plurality of resilient spring legs attached to said box, said legs having free end portions engageable with one form surface for biasing said box in a direction to engage said box open end with an opposite form surface, and an elongated bendable strap attached to said box for attachment to reinforcement rods between spaced forms.
- 32. A mud box having an open end, a plurality of resilient spring legs attached to said box, said legs having free end portions engageable with one form surface for biasing said box in a direction to engage said box open end with an opposite form surface, said spring legs being defined by a pair of spring members, each spring member having a central attachment portion with a pair of spring legs extending therefrom, and said attachment portions being attached to said box in perpendicular relationship to one another to provide four spaced-apart spring legs extending outwardly from said box.
-
34. A mud box having an open end, a plurality of resilient spring legs attached to said box, said legs having free end portions engageable with one form surface for biasing said box in a direction to engage said box open end with an opposite form surface, said spring legs supporting said box between a pair of spaced-apart parallel concrete forms with inner form surfaces spaced-apart between 6-8 inches.
-
35. A mud box having an open end, a plurality of resilient spring legs attached to said box, said legs having free end portions engageable with one form surface for biasing said box in a direction to engage said box open end with an opposite form surface, each spring leg having a reversely curved bifurcated end portion to provide a pair of spaced-apart reversely curved support end portions each of which has a width that is not greater than the space between them.
- 36. A mud box having a bottom wall and an open end opposite from said bottom wall, said bottom wall having an external surface, a centrally located attachment projection integrally formed on said external surface and extending outwardly therefrom for attaching support legs to said box, and a plurality of abutments on said external surface of said bottom wall spaced outwardly from said attachment projection and forming abutment guideways that extend perpendicular to one another past said attachment projection.
- 38. A support kit for attachment to an electrical mud box, said kit including a pair of generally U-shaped spring leg members and a flat bendable strap, each spring leg member having a central attachment portion with an attachment opening therethrough, and said strap having a central attachment opening therethrough.
- 40. An electrical box molded of plastic material, said box having a bottom wall with an external surface, a centrally located projection molded integrally with said bottom wall and extending outwardly from said external surface thereof, at least one flat bendable metal strap having an opening therethrough, said projection and said opening being configured for reception of said projection through said opening in an alignment orientation of said projection and opening, and said projection and opening being configured for preventing movement of said projection through said opening when said strap and projection are rotated out of said alignment orientation with said projection extending through said opening.
- 43. An electrical box molded of plastic material, said box having a bottom wall with an external surface, a pair of elongated flat bendable metal straps, said external surface and said metal straps being configured for attachment of said straps to said bottom wall with said straps extending generally perpendicular to one another in overlying relationship.
- 45. An electrical box of plastic material, said box having a bottom wall with an external surface, a projection extending outwardly from said external surface, said projection having an enlarged head spaced outwardly from said external surface, a pair of elongated flat bendable metal straps having openings therethrough, said openings being configured for receiving said enlarged head therethrough, said enlarged head and at least one of said openings on at least one of said straps being configured to provide reception of said enlarged head through said one opening and to prevent withdrawal of said head from said opening after rotating said one strap about said projection.
