Block out chair system used to make a block out or a pass-through in a concrete slab

Abstract

A block out chair system that is used to make a block out for a railing or to make a pass-through in a concrete slab. the block out chair system is a circular flat base that defines a circular aperture within the circular flat base, at least three supports that extend perpendicularly outward from the circular flat base, a hollow cylinder that has a perimeter wall that extends linearly outward from the at least three supports, the hollow cylinder defines a plurality of teeth that are configured to secure a foam cylinder, and a solid foam cylinder that is inserted within the hollow cylinder.

Claims

1. A block out chair system that is used to make a block out for a railing or to make a pass-through in a concrete slab, the block out chair system comprises: a circular flat base that defines a circular aperture within the circular flat base, the circular aperture has a diameter that in at least 4 inches in diameter and that is no more than 6 inches in diameter, the circular flat base defines a solid ring that is two inches in width, the flat circular base is configured to be secured on a wooden form that is used to create the block out or the pass through in the concrete slab; at least three supports that extend perpendicularly outward from the circular flat base, the at least three supports are equally distanced from each other and are all at an equal distance from the center of the circular flat base; a hollow cylinder that has a perimeter wall that extends linearly outward from the at least three supports, and the perimeter wall of the hollow cylinder are from at least one inch in length and at most two inches in length, the hollow cylinder defines a plurality of teeth that are configured to secure a foam cylinder; and a solid foam cylinder that is at least 4 inches in diameter and that is no more than 6 inches in diameter that is inserted within the hollow cylinder.

2. The block out chair system that is used to make a block out for a railing or to make a pass-through in a concrete slab of claim 1, wherein the perimeter wall of the hollow cylinder defines at least one cutout.

DESCRIPTION

(11) As seen in FIGS. 1-2, the present invention is a block out chair system 100 that is used to make a block out for a railing or to make a pass-through in a concrete slab.

(12) The block out chair system 100 comprises of a circular flat base 10 that defines a circular aperture 12 within the circular flat base, the circular aperture 12 has a diameter that in at least 4 inches in diameter and that is no more than 6 inches in diameter, the circular flat base 10 defines a solid ring 10a that is two inches in width, the flat circular base 10 is configured to be secured on a wooden form 200 that is used to create the block out or the pass through in the concrete slab 300. At least three supports 20 that extend perpendicularly outward from the circular flat base 10, the at least three supports 20 are equally distanced from each other and are all at an equal distance from the center of the circular flat base 10b. A hollow cylinder 30 that has a perimeter wall 30a that extends linearly outward from the at least three supports 20, and the perimeter wall 30a of the hollow cylinder 30 are from at least one inch in length and at most two inches in length, the hollow cylinder 30 defines a plurality of teeth 32 that are configured to secure a solid foam cylinder 40. And, a solid foam cylinder 40 that is at least 4 inches in diameter and that is no more than 6 inches in diameter that is inserted within the hollow cylinder 30.

(13) In an embodiment of the present invention, the perimeter wall of the hollow cylinder defines at least one cutout 34.

(14) An advantage of the present invention is that it provides a block out chair system that prevents the shifting of a foam block out when concrete is poured on to a wooden support structure.

(15) Another advantage of the present invention is that it provides a block out chair system that saves time when placing a foam block out on a wooden support structure in which concrete is poured.

(16) Yet another advantage of the present invention is that it provides block out chair system that saves a contractor from having to fix a block out that is incorrectly poured.

(17) Still yet another advantage of the present invention is that it provides a block out chair system that saves a contractor time and money.

(18) While the inventor's description contains many specificities, these should not be construed as limitations on the scope, but rather as an exemplification of several preferred embodiments thereof. Many other variations are possible. Accordingly, the scope should be determined not by the embodiments illustrated, but by the specification, the drawings, and the appended claims and their legal equivalents.
