ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to roofline ventilators for peaked roofs, and more particularly to a roofline ventilator which is inexpensive and easy to assemble accurately and quickly.
BACKGROUND OF THE INVENTION
Numerous roof ventilators are known in the art. However, there are problems with such prior art ventilators including inefficient operation as well as the cost and ease of manufacture and installation thereof.
BRIEF SUMMARY OF THE INVENTION
In accordance with the present invention, a roofline ventilator assembly is disposed longitudinally along a peak of a roof over an elongate opening therein. The ventilator assembly includes an elongate vent and paired end brackets located at a spaced interval from each other along a longitudinal axis adjacent to the peak of the roof. Each end bracket includes (a) a central peaked portion which extends laterally above the peak, (b) first and second holding portions located at opposite lateral sides of the peaked portion, (c) respective first and second upper holding members located in a respective first and second holding portion, and (d) respective first and second lower holding members located in the respective first and second holding portion below a respective first and second upper holding member.
The vent includes an elongate ridge cap which extends longitudinally between the end brackets and which is attached to and extends over a portion of each end bracket. The ridge cap includes (a) a central cap portion which extends laterally over and between respective central peaked portions of underlying end brackets, and (b) first and second wings extending laterally from opposite sides of the central peaked portion to a lateral position beyond the holding portions of the underlying end brackets.
The vent also includes first and second elongate upper barrier members which respectively extend longitudinally between the respective first and second holding portions of the end brackets. Each upper barrier member has an end profile of J shape so that in profile the upper barrier member has a short leg, a long leg parallel to the short leg, and a connecting piece. Each upper barrier member is disposed such that opposite longitudinal end portions of the short leg are held by an associated lower holding member of an associated holding portion with opposite longitudinal end portions of the connecting piece located outside of the associated holding portion and with opposite longitudinal end portions of the long leg located above the associated holding portion and underneath of an associated wing of the ridge cap.
The vent further includes first and second elongate lower barrier members which respectively extend longitudinally between the respective first and second holding portions of the end brackets. Each lower barrier member has an end profile of J shape so that in profile the lower barrier member has a short leg, a long leg parallel to the short leg, and a connecting piece. Each lower barrier member is disposed such that opposite longitudinal end portions of the short leg are held by an associated upper holding member of the associated holding portion with opposite longitudinal end portions of the connecting piece located inside of the associated holding portion and with opposite longitudinal end portions of the long leg located below the associated holding portion and extending away from the end bracket for attachment to the roof. Thus, each lower barrier member and associated upper barrier member form in profile an S-shaped air ventilation path from an area below the central cap portion of the ridge cap to an area outside of the associated holding portion and above an associated long leg of the lower barrier member.
The vent preferably further includes first and second elongate screen members which respectively extend longitudinally between the end brackets. Each screen member (a) is attached to the respective end brackets, and (b) is disposed in a respective S-shaped air ventilation path to screen air passing along the respective S-shaped path. Each screen member preferably has an end profile of J shape so that in profile the screen member has a short leg, a long leg parallel to the short leg, and a connecting piece. Thus, each screen member is disposed such that opposite longitudinal end portions of one of the short leg and long leg are held by an associated one of the upper holding member and lower holding member of the associated holding portion. In the preferred embodiment, each opposite longitudinal end portion of the long leg of the screen members is held by an associated upper holding member of the associated holding portion such that each connecting piece of the screen members is disposed between an associated long leg of the upper barrier member and an associated short leg of the lower barrier member.
The roofline ventilator assembly of the present invention preferably further includes a plurality of mid brackets disposed intermediate the end brackets along the longitudinal axis. Each mid bracket includes (a) a central peaked portion which extends laterally, (b) first and second holding portions located at opposite lateral sides of the peaked portion of the mid bracket, (c) respective first and second upper holding members located in a respective first and second holding portion of the mid bracket, and (d) respective first and second lower holding members located in the respective first and second holding portion of the mid bracket below a respective first and second upper holding member of the mid bracket. With this construction, respective mid portions of respective first and second upper barrier members, respective mid portions of respective first and second lower barrier members, and respective mid portions of respective first and second screen members are respectively received in one of the first and second upper and lower holding members of the mid brackets.
Where the roofline ventilator has a plurality of mid brackets, each screen member includes a plurality of cutouts at spaced intervals in which associated mid brackets are received as the associated screen member is held by the associated the mid bracket.
In the preferred embodiment, the end brackets, the ridge cap, the upper barrier members, the lower barrier members, and the screen members are all made of a plastic material, such as vinyl.
Further in the preferred embodiment, the holding members of the end brackets and of the mid brackets are formed by laterally open slots therein. In each slot, there is provided at least one upper and lower longitudinal bead extending respectively from opposite upper and lower walls defining the slot. More preferably, there are at least three of the beads, with one bead extending from one wall being located laterally intermediate two other beads extending from the other wall.
Each mid bracket preferably includes a lower outside indentation. In addition, each bracket is longitudinally hollow beneath the central peaked portion thereof and is longitudinally hollow about the holding members, except for an outside end wall extending in a vertical plane of the end brackets. Further, a profile of the central peaked portion of each end bracket matches a profile of the ridge cap such that the central peaked portion engages the ridge cap thereat. Still further, the ridge cap has first and second lateral edges which extend beyond the associated holding portions of the mid brackets and which lateral edges are angled down towards the roof.
It is an advantage of the present invention that a roofline ventilator is provided which is easy and cheap to make.
It is also and advantage of the present invention that a roofline ventilator is provided which is easy and quick to install.
It is another advantage of the present invention that a roofline ventilator is provided which is easy to precisely assemble.
Other features and advantages of the present invention are stated in or apparent from detailed descriptions of presently preferred embodiments of the invention found hereinbelow.
