10 Claims. (Cl. 98-37) This invention relates generally to a roof ventilating device and, more particularly, to a roof ventilating device for a fiat roofed building or for a building without an attic.

One object of the present invention is the provision of a roof ventilating device for ventilating the air space disposed below the roof of a building, said device being efiective to prevent the formation of moisture in said air space.

Another object of the present invention is the provision of a roof ventilating device of the above char acter which functions as a gravel stop and finishing structure for the roof edge.

Another object of the present invention is the provision of a roof ventilating device of the above character which provides air flow to the air space defined below the roof of a building from the atmosphere free of insects and foreign matter.

Yet another object of the present invention is the provision of lengths of roof ventilating devices of the above character which are adapted to be interconnected to each other in fluid-tight relation to define a finished roof edge, said devices being of simple design and construction, economical to manufacture and highly eificient in the accomplishment of their intended purposes.

The above and other objects, features and advantages of the present inventionwill be more fully understood from the following description considered in connection with the accompanying illustrative drawings.

In the drawings which illustrate the best modes now contemplated by me for carrying out my invention:

Fig. 1 is a sectional side elevational view of a fragmentary portion of a building roof;

Fig. 2 is a sectional perspective view of a corner of a roof with parts broken away to reveal structural details;

Fig. 3 is a sectional perspective view of a fragmentary portion of a roof pursuant to a slightly modified form of the present invention with parts broken away to reveal structuraldetails;

Fig. 4 is a sectional side elevational view of a fragmentary portion of a roof according to another modified form of the present invention; and

Fig. 5 is a view similar to Fig. 4 of yet another modified form of the present invention.

Referring to the drawings and, more particularly, to Figs, 1 and 2 thereof, there are shown lengths of roof ventilating devices secured to the building 12 in the manner to be described in detail hereinafter, said lengths of roof ventilating devices being secured to each other in end-to-end relation to define the finished roof edge of the building. The building 12 is provided with a generally flat roof 14 and said building may be of any conventional design and construction. The building 12 illustrated in Figs. 1 and 2 comprises a series of laterally spaced and longitudinally extending headers or roof supports 16 which are-securedto the lower faces 18 of the roofing boards 20, saidroofing boards being con- 2,777,381 Fatented Jan. 15, 1957 nected to each other in any conventional manner to collectively define the base structure 22 of the roof 14. The ceiling panel 24 is secured to a series of headers 16 in spaced disposition from the roofing boards 20 and suitably disposed in the air space 26 defined between the roofing boards 20 and the ceiling panel 24 are bags of insulation material 28 schematically indicated in Fig. 1. The inner wall 30 is suitably integrated with the ceiling panel 24 and the member 31, there being provided sheathing 32 in laterally spaced relation with the inner wall 30 with the member 31 transversely extending therebetween. The siding 34 which constitutes an external building wall is secured to the sheathing 32 in face-to-face relation and said siding is secured to the outermost header 16' through the intermediation of the member 36. Pursuant to the present invention each of the headers 16 is provided with a series of spaced openings 38 which extend transversely therethrough, said openings in conjunction with the roof ventilating devices 10 being adapted to provide ventilation for the space 26. The devices 10 are provided in suitable lengths and are adapted to be secured to each other in end-to-end fluid-tight relation to define the finished edge 84 of the roof 14.

The roof ventilating device 10 comprises an enclosure 4d having mutually converging upper and lower walls 42 and 44, respectively which define the longitudinally extending opening 46. The walls 42 and 44 are interconnected at their outer edges by the side or outer wall 48 which is provided with a finished outer face 50. The walls 42, 44 and 48 definethe substantially triangular shaped enclosure 40, and the generally triangular shaped opening 46 defined between said walls extends for the length of the enclosure. In order to provide for a flow of air through the opening 46 there is provided a series of air inlet openings 52, and a series of air outlet openings 54 laterally spaced therefrom, it being apparent that said inlet and outlet openings are in fluid communication with the opening 46. Any desired number and shape of openings 52 and 54 may be provided and it, is to be noted that the air inlet openings 52 are disposed in the wall 44 in the region of the Wall 48 and the air outlet openings 54 are disposed in said wall inwardly of the openings 52. Disposed in the opening 46 for the length thereof is screening 56 which in the illustrated embodiment of Figs. 1 and 2 is substantially L-shaped having a part 58 which is disposed in overlying relation with the inner face of the lower wall 44 and a part 60.

which is disposed in overlying relation with the inner face of the upright connecting wall 48, said screening preventing the entrance of insects and foreign matter into the air space 26 through the air inlet and outlet openings 52 and 54, respectively, when the roof ventilating devices 10 are installed on the building 12 in the manner to be described in detail hereinafter. The upper wall 42 is inclined relative to the lower wall 44, the latter wall being adapted to be disposed in horizontal disposition in the installed condition of the roof ventilating devices 10, it being understood that if desired for certain installations said upper wall need not be so inclined and may be disposed parallel to said lower wall. The inclined upper wall 42 is adapted for the support of roofing material and said upper wall, at an outer edge portion thereof, is provided with an upstanding abutment 62 which constitutes a gravel stop as will be apparent from the description which follows. Forming a continuation of the Wall 48 and depending from the outer edge of the lower wall 44 is a longitudinally extending portion 64 which is adapted to shelter and conceal the air inlet opening 52 from the elements. The

3 longitudinally extending portion 64 extends for the full length of the enclosure 40.

In order to secure the enclosure 40 to the roof there is provided a longitudinally extending strip 66 which forms a continuation of the wall 44, said securement strip being provided with a series of openings 68 which are adapted for the reception therethrough of suitable fastening devices such as nails 70. There is also provided a securement strip 72 which depends from an intermediate portion of the lower wall 44, said securement strip extending for the length of the enclosure 40 and being provided with a series of preformed openings 74 which are adapted for the reception of the nails or other suitable fastening devices 76.

In practice, the device is installed on the building 12 by nailing or otherwise securing the securement strips 66 and 72 to the roofing boards 20. More particularly, the roof ventilating device 10 is fitted over associated roofing boards with said device being secured to said roof boards through the intermediation of the securement strips 66 and 72. The siding 34 is secured in place subsequent to the installation of the roof ventilating devices, it being noted that in the installed condition of the roof ventilating devices the air inlet openings 52 will be in fiuid communication with the atmosphere and the air outlet openings 54 will be in fluid communication with the air space 26 through the series of openings 38. Thus the air outlet openings 54 register with the air space defined between the siding 34 and the header 16'. As previously pointed out, all of the headers 16 are provided with a series of ventilating openings 38 whereby to provide ventilation for the entire interior space 26 disposed below the roof 14 of the building 12.

The series or lengths of roof ventilating devices 10 are interconnected to each other in end-to-end relation to define the peripherally continuous roof edge 84 of the roof 14. In order to provide a fluid-tight securement between the lengths of ventilating devices 10, there is provided a generally triangular-shaped sleeve 86 which is dimensioned substantially complementary to the opening 46, said sleeve being adapted to interfit in an adjacent pair of openings 46 of an adjacent pair of devices 10. Thus the sleeve 86 internally covers the joint defined by the adjacent peripheral edges 88 and 90 of a companion pair of devices 10 which are interconnected by said sleeve, it being noted that said edges are spaced slightly from each other in order to provide for the normal expansion and contraction of the series of devices 10. The peripheral edges 88 and 90 are externally covered and the joint defined thereby is made externally fluid-tight by means of the peripherally extending cover strip 92, the latter conforming to the peripheral contour of the device 10. The cover strip 92 may be formed of sheet metal or any other suitable material and extends from the securement strip 66 to the shelter strip 64 with said cover strip being bent around said shelter strip in the manner shown in Fig. 2. Thus the joint defined between each adjacent pair of devices 10 is effectively internally and externally covered by means of the sleeve 86 and cover strip 92, to thereby provide a fluid-tight joint between adjacent sections or lengths of roof ventilating devices. Each section or length of roof ventilating device is secured to an adjacent ventilating device in the aforedescribed manner except at the roof corner portions where the adjacent peripheral edges of a companion pair of ventilating devices are secured together by welding or the like to define the peripheral welded seam 94. Thus the ventilating devices 10' and 10", which define a corner portion of the roof edge 84, have their adjacent peripheral free edges formed with complementary interfitting inclinations to thereby form the peripherally extending welded seam 94 on the securement of said adjacent peripheral edges.

Superposed on the outer face of the roofing boards 20 are a series of layers of tar paper or similar roofing material 96, there being provided one or more layers of gravel 98 supported on said tar paper. It will be understood that the tar paper and

gravel

96 and 98, respectively, will extend over the walls 42 of the devices 10 and will be supported thereby with the upstanding abutments 62 constituting a gravel stop for the layers of gravel 98. From the above it will therefore be apparent that the roofing material disposed on the roofing boards 20 extends onto the upper walls 42 of the roof ventilating devices 10 and terminates at the upright abutments 62. The devices 10 aforedescribed may be formed of any suitable material and may be of any desired construction and in the embodiment illustrated in Figs. 14 said devices are of one-piece extruded construction. Thus by way of example the roof ventilating devices 10 may be formed of a suitable metallic material such as aluminum, brass, copper or stainless steel or a non-metallic material such as a suitable plastic, and may be of a molded or extruded construction, or may be fabricated from sheet material.

With reference to Fig. 3, there is shown a slightly modified building construction arrangement in which the headers are provided with a series of V-shaped openings 100 in order to provide ventilation for the air space defined below the roof. Thus, if desired, the ventilating openings for the headers may be of circular shape as indicated at 38 or may be V-shaped as indicated at 100 in Fig. 3, it being understood that the V-shaped openings 100 in building construction 12 function in an identical manner with the ventilating openings 38 aforedescribed.

With reference to Fig. 4, there is shown a modified form of roof ventilating device 102 which is similar to the roof ventilating devices 10 aforedescribed except in the manner to be specifically pointed out hereinafter. The ventilating device 102 is secured to the roofing boards 20 by means of the nails or fastening elements 104, said nails extending through suitable openings provided in said device and through said roofing boards into the header 16. It is to be noted that the laterally projecting longitudinally extending strip 106 of the device 102 is non-per forated and that said device eliminates the need of 21 depending securement strip corresponding to the strip 72 of the device 10 aforedescribed. The lower wall 108 has a shoulder portion 110 depending therefrom and said shoulder portion is adapted to interfit with an adjacent edge portion 111 of the siding 34. The bottom wall 108 is further provided with a pair of aligned longitudinally extending grooves 112 which are adapted for the reception of the screening strip 114, the latter being adapted to prevent the entrance of insects and foreign matter into the air space defined below the roof in the manner aforedescribed with reference to the screening 56. Except in the respects specifically noted above the ventilating device 102 is similar to the ventilating devices 10 aforedescribed and is similarly adapted for integration with the roofing material described above and to serve as a gravel stop.

With reference to Fig. 5 there is shown a modified form of the present invention in which the roof ventilating device 116 has spaced upper and

lower walls

118 and 120, respectively which define a longitudinal opening 122 therebetween, said upper and lower walls being interconnected by the side wall 124 which has a finished outer face. The lower horizontal wall is substantially narrower than the upper inclined wall 118 and terminates in a depending longitudinally extending securement strip 126 having preformed openings 127. The relatively narrow lower wall 120 is provided with a series of air in let openings 128 which provide fluid communication between the atmosphere and the opening 122. The longitudinally extending opening 122 is adapted for fluid communication with the air space 130 defined below the roof 132 in the manner to be described hereafter. The roofing boards 133 are provided with a series of openings 134 which extend transversely therethrough and which are in fluid communication with the air space 130. In the installed condition of the roof ventilating devices 116 the air space 130 is ventilated'by means of "the air flow which enters the openings 128 and which flows through the

openings

122 and 134. The roof ventilating device 116 may be formed of any suitable material, for example sheet metal or any other suitable sheet material, and said device is adapted to be installed in a building structure by means of the nails 138 which extend through the openings 139 provided in the securement strip 140 constituted by a laterally projecting end portion of the wall 118 and by the nails 142 which extend through the openings 127 provided in the depending strip 126. It is to be noted that the depending strip 126 is secured between the siding 144 and the roof support member 146 whereby it will be apparent that the siding 124 is secured in position subsequent to the installation of the device 116. The device 116 is provided with an upstanding abutment 62' corresponding to the abutment 62 above described and is further provided with a shelter strip 64' corresponding to the shelter strip 64 above described. Screening 148 is provided to prevent the entrance of insects and foreign matter into the air space 130 and said screening overlies the series of air inlet openings 128. Thus as shown in Fig. 5 the marginal strip 150 of screening 148 is claimed between the portions 151 and 151' which define the shelter strip 64 with the opposite marginal strip 152 being clamped in position between the roofing board 133 and adjacent portions of the depending securement strip 126. Thus the roof ventilating device 116 is of an open construction with the openings 134 provided in the roofing boards 133 constituting the air outlet means for ventilating the air space 130 defined by and below the roof. The devices 116 are interconnected in fiuidtight relation by means of cover strips 156 which correspond to the cover strips 92 aforedescribed.

From the above it will. be apparent that in the installed condition of the roof ventilating devices aforedescribed, said devices will be effective to ventilate the air space disposed below the roof of a building and to prevent the formation of moisture in such air space. The roof ventilating devices function as a gravel stop and as a finishing structure for the roof edge, said devices being provided with screening to prevent the entrance of insects and foreign matter into the air space to be ventilated. The ventilating devices, above described, are adapted to be interconnected to each other in fluid-tight relation to define the finished roof edge, it being noted that the devices and 102 are interconnected to each other by means of sleeves 86 and cover strips 92 with the devices 116 being interconnected to each other by the use of cover strips 156 which correspond to the cover strips 2.

While I have shown and described the preferred embodiments of my invention, it will be understood that various changes may be made in the present invention without departing from the underlying idea or principles of the invention within the scope of the appended claims.
