Modular grid
A modular grid comprises a faceplate having at least one front opening and at least two tabs on its periphery, a sleeve configured to abut on the faceplate, and at least two attachments, each attachment being configured for insertion into an opening formed in a corresponding one of the at least two tabs and into a corresponding opening formed on the perimeter of the sleeve. The modular grid may be mounted on an extremity of a conduit, whether at its inlet or outlet side, and be shaped for mating with the extremity of the conduit. A perimeter of the faceplate may be circular, square, oval, rectangular, triangular, pentagonal, hexagonal, or octagonal.
1. A modular grid, comprising:
a faceplate having at least one front opening and at least two tabs on its periphery;
a sleeve configured to abut on the faceplate; and
at least two attachments, each attachment being configured for insertion into an opening formed in a corresponding one of the at least two tabs and into a corresponding opening formed on the perimeter of the sleeve,
the sleeve being formed by bending or folding a rectangular strip,
the sleeve comprising an extremity of the rectangular strip overlapping over an opposite extremity of the rectangular strip.
2. The modular grid of claim 1 , wherein the sleeve is an outer sleeve adapted for mounting on an outer face of an extremity of a conduit.
3. The modular grid of claim 2 , wherein each attachment is configured for insertion in a corresponding opening formed on the extremity of the conduit.
4. The modular grid of claim 1 , wherein the sleeve is an inner sleeve adapted for mounting on an inner face of an extremity of a conduit.
5. The modular grid of claim 4 , wherein each attachment is configured for insertion in a corresponding opening formed on the extremity of the conduit.
6. The modular grid of claim 1 , wherein the perimeter of the faceplate is selected from a circle, an oval, a square, a rectangle, a triangle, a pentagon, an hexagon, and an octagon.
7. The modular grid of claim 1 , wherein the faceplate comprises a plurality of front openings.
8. The modular grid of claim 7 , wherein the front openings collectively extend over a major portion of an area defined by the perimeter of the faceplate.
9. The modular grid of claim 7 , wherein the front openings form a plurality of parallel slots.
10. The modular grid of claim 7 , wherein the front openings form a rectangular grid.
11. The modular grid of claim 1 , wherein the faceplate is made of a material selected from galvanized steel, stainless steel, aluminum, and polymer.
12. The modular grid of claim 1 , wherein the sleeve is made of a material selected from galvanized steel, stainless steel, aluminum, and polymer.
13. The modular grid of claim 1 , wherein one of the openings on the perimeter of the sleeve is formed in the extremities of the rectangular strip.
14. The modular grid of claim 1 , wherein the faceplate has a first perimeter and the sleeve has a second perimeter configured for matching the first perimeter of the faceplate.
15. The modular grid of claim 1 , wherein the at least two tabs comprises two tabs being diametrically opposed on the periphery of the faceplate.
16. The modular grid of claim 1 , wherein each of the at least two tabs is foldable for placement over the sleeve when assembling the modular grid.
17. The modular grid of claim 1 , wherein the attachments are selected from screws, bolts and rivets.
18. The modular grid of claim 1 , wherein each of the attachments comprises a knob or a handle connected to a bolt.
