Abstract

A ventilation hood is mounted to an underside of a cabinet, including a bottom panel and a lower support frame positioned above a cooking appliance, by first and second brackets secured below the cabinet at spaced positions aligned with outermost edge portions of the lower support frame and at least one fastener assembly secured to a front portion of the ventilation hood. Multiple embodiments are disclosed for the at least one fastener assembly, including tabs bent from a housing of the ventilation hood, feet threadably attached to the hood, mounting blocks including snap connectors, threaded fasteners, and pinned bolts.

First claim

We claim:

1. A system comprising: a ventilation hood; a cabinet including a bottom panel and a lower support frame positioned above a cooking appliance; first and second brackets mounted below, and not attached to, the cabinet at spaced positions aligned with outermost edge portions of the lower support frame, each of said first and second brackets including a projection, each projection engaging and supporting a rear portion of the ventilation hood; and at least one fastener assembly attaching a front portion of the ventilation hood to the cabinet.

2. The system according to claim 1 , wherein the first and second brackets are fixedly secured to a wall, against which the cabinet is mounted, at positions directly below the cabinet and aligned with the outermost edge portions of the lower support frame.

3. The system according to claim 1 , wherein the ventilation hood includes a housing from which are bent spaced flexible tabs which form part of the at least one fastener assembly, each of the flexible tabs being secured directly to the lower support frame of the cabinet.

4. The system according to claim 3 , wherein the housing of the ventilation hood includes enlarged openings formed, at least in part, upon bending the flexible tabs, said at least one fastener assembly being further formed by threaded fasteners securing the flexible tabs to the lower support frame, with the enlarged openings providing access to the flexible tabs through the housing.

5. The system according to claim 1 , wherein the at least one fastener assembly includes a pair of feet members adjustably attached to and projecting up from the ventilation hood and mechanical fasteners extending through the bottom panel of the cabinet and into the feet members.

6. The system according to claim 5 , wherein each of the feet members includes a threaded body portion having a bore extending entirely there through.

7. The system according to claim 6 , wherein each of the feet members also includes an upper portion, having a head configured to receive a tool, and a lower portion, and wherein the bore at the lower portion is polygonal in shape.

8. The system according to claim 1 , wherein the at least one fastener assembly includes mounting blocks, from which first and second connectors extend, the mounting blocks being secured at frontal corner portions of the lower support frame with the first and second connectors projecting downward from the mounting blocks and being attached to the ventilation hood.

9. The system according to claim 8 , wherein the first and second connectors are snap-connected to the ventilation hood.

10. The system according to claim 1 , wherein the at least one fastener assembly includes first and second mechanical fasteners interconnected by a plate, each of the first and second mechanical fasteners extending through both the bottom panel and the ventilation hood, while the plate is positioned against the bottom panel.

11. The system according to claim 1 , wherein the at least one fastener assembly includes zip strips, with each zip strip including a head portion positioned against the bottom panel, an elongated body portion extending through both the bottom panel and the ventilation hood, and a fastener element ratcheted onto the elongated body portion.

12. The system according to claim 1 , wherein the at least one fastener assembly includes bolts extending through both the bottom panel of the cabinet and the ventilation hood.

13. The system according to claim 12 , wherein the at least one fastener assembly further includes pins extending through transverse holes in the bolts.

14. A system comprising: a ventilation hood; a cabinet including a bottom panel and a lower support frame positioned above a cooking appliance; first and second brackets mounted against a wall underneath the cabinet at spaced positions aligned with outermost edge portions of the lower support frame, each of said first and second brackets including a projection, each projection engaging and supporting a rear portion of the ventilation hood; and at least one fastener assembly attaching a front portion of the ventilation hood to the cabinet.

15. The system according to claim 14 , wherein the first and second brackets are fixedly secured to the wall, against which the cabinet is mounted, at positions directly below the cabinet and aligned with the outermost edge portions of the lower support frame.

16. The system according to claim 14 , wherein the ventilation hood includes a housing from which are bent spaced flexible tabs which form part of the at least one fastener assembly, each of the flexible tabs being secured directly to the lower support frame of the cabinet.

17. The system according to claim 16 , wherein the housing of the ventilation hood includes enlarged openings formed, at least in part, upon bending the flexible tabs, said at least one fastener assembly being further formed by threaded fasteners securing the flexible tabs to the lower support frame, with the enlarged openings providing access to the flexible tabs through the housing.

18. The system according to claim 14 , wherein the at least one fastener assembly includes a pair of feet members adjustably attached to and projecting up from the ventilation hood and mechanical fasteners extending through the bottom panel of the cabinet and into the feet members.

19. The system according to claim 18 , wherein each of the feet members includes a threaded body portion having a bore extending entirely there through.

20. The system according to claim 19 , wherein each of the feet members also includes an upper portion, having a head configured to receive a tool, and a lower portion, and wherein the bore at the lower portion is polygonal in shape.

21. The system according to claim 14 , wherein the at least one fastener assembly includes mounting blocks, from which first and second connectors extend, the mounting blocks being secured at frontal corner portions of the lower support frame with the first and second connectors projecting downward from the mounting blocks and being attached to the ventilation hood.

22. The system according to claim 21 , wherein the first and second connectors are snap-connected to the ventilation hood.

23. The system according to claim 14 , wherein the at least one fastener assembly includes first and second mechanical fasteners interconnected by a plate, each of the first and second mechanical fasteners extending through both the bottom panel and the ventilation hood, while the plate is positioned against the bottom panel.

24. The system according to claim 14 , wherein the at least one fastener assembly includes zip strips, with each zip strip including a head portion positioned against the bottom panel, an elongated body portion extending through both the bottom panel and the ventilation hood, and a fastener element ratcheted onto the elongated body portion.

25. The system according to claim 14 , wherein the at least one fastener assembly includes bolts extending through both the bottom panel of the cabinet and the ventilation hood.

26. The system according to claim 25 , wherein the at least one fastener assembly further includes pins extending through transverse holes in the bolts.
