Abstract
A roll-form roof ridge vent having alignment means to facilitate ease of installation. The indeterminate-length, single-sheet vent is provided with a pliable medial hinge strip, or a set of expandable live hinges, which enable the otherwise straight vent to be laterally and/or angularly repositioned from its substantially straight configuration. Thus, lateral adjustments can be made to the positioning of the vent as it is being installed so that the vent is centered throughout its length over the roof ridge. The lateral adjustments do not result in buckling of the vent or unwanted distortion.
Claims20
A roof ridge vent for installation overlying an open roof ridge to provide ventilation to a space beneath a roof, comprising:
- a continuous, indeterminate-length, single-sheet, roll-form web of plastic material, said web capable of being rolled lengthwise into a spiral roll during manufacture and unrolled lengthwise in a substantially straight direction during installation on the roof ridge to form a continuous, one-piece roof ridge vent along the roof ridge;
- and
- alignment means integrally formed on said web so that said web is capable of being laterally repositioned along its length from said substantially straight lengthwise direction of said web;
- said alignment means including a plurality of expandable live hinges formed transversely at spaced locations on said web, said expandable live hinges permitting lateral angular deflections of said web along its relatively straight length during installation to ensure that said web is centered along its length over the roof ridge;
- whereby during installation said web can be aligned with the roof ridge.
A roof ridge vent for installation overlying an open roof ridge to provide ventilation to a space beneath a roof, comprising:
- a continuous, indeterminate-length, single-sheet, roll-form web of plastic material, said web capable of being rolled lengthwise into a spiral roll during manufacture and unrolled lengthwise in a substantially straight direction during installation on the roof ridge to form a continuous, one-piece roof ridge vent along the roof ridge;
- and
- alignment means integrally formed on said web so that said web is capable of being laterally repositioned along its length from said substantially straight lengthwise direction of said web;
- said alignment means being provided by a lengthwise central hinge strip, said hinge strip being made of an elastomeric material which permits the roof ridge vent to be laterally deflected and centered over said open roof ridge;
- whereby during installation said web can be aligned with the roof ridge.
A roof ridge vent for installation on a roof overlying an open roof ridge, comprising:
- a continuous, indeterminate-length, single-sheet, roll-form web of thermoformable material, said web capable of being rolled lengthwise into a spiral roll during manufacture and unrolled lengthwise in a substantially straight direction during installation on the roof ridge;
- a plurality of hollow spacer elements thermoformed integrally on, and projecting in a spaced relation from, a face of said web for spacing said face of said single-sheet web from the roof thereby creating a path for ventilation between the roof and said web face when said web is installed on the roof ridge;
- at least one continuous length of air permeable filter media attached to said web face for preventing weather and insect infiltration into said ventilation path;
- and
- means integrally formed on said web for permitting said web, along said web length, to be laterally repositioned relative to said substantially straight lengthwise direction so that said web can be realigned with and centered over, the roof ridge during installation;
- said means including a plurality of expandable live hinges formed transversely and integrally at spaced locations on said web, said expandable live hinges permitting lateral deflections of said web along its relatively straight length during installation to ensure that said web is centered throughout its length over the roof ridge.
A roof ridge vent for installation on a roof overlying an open roof ridge, comprising:
- a continuous, indeterminate-length, single-sheet, roll-form web of thermoformable material, said web capable of being rolled lengthwise into a spiral roll during manufacture and unrolled lengthwise in a substantially straight direction during installation on the roof ridge;
- a plurality of hollow spacer elements thermoformed integrally on, and projecting in a spaced relation from, a face of said web for spacing said face of said single-sheet web from the roof thereby creating a path for ventilation between the roof and said web face when said web is installed on the roof ridge;
- at least one continuous length of air permeable filter media attached to said web face for preventing weather and insect infiltration into said ventilation path;
- and
- means integrally formed on said web for permitting said web, along said web length, to be laterally repositioned relative to said substantially straight lengthwise direction so that said web can be realigned with and centered over, the roof ridge during installation;
- said web including a pair of rigid lengthwise-extending outer flaps, and said means being provided by a lengthwise central hinge strip which is coextruded with, and integrally formed between, said outer flaps, and wherein said central hinge strip is made of an elastomeric material so that said central hinge strip is capable of effecting realignment of said web over the roof ridge.
