Application June 27, 1955, Serial No. 518,243
1 Claim. (Cl. 98-37) This invention relates generally to Ventilating devices and more specically to ventilators of the louver variety.
A primary object of this invention is the provision of a Ventilating device for use in homes and other building structures whereby air is allowed to pass freely therein while at the same time excluding the passage therein of rain and insects.
A further object is the provision of a Ventilating device which may be easily, yet securely, mounted at any desirable location in the house or building in which it is being utilized.
Another object is the provision of a Ventilating device of the louver variety having novel and improved means for removably positioning a wire mesh screen adjacent the louvers.
Still another object is the provision of a Ventilating device which can be manufactured economically but which is of rugged and durable construction.
Other objects, features and advantages of the invention will become apparent as the description thereof proceeds when considered in connection with the accompanying illustrative drawings.
In the drawings which illustrate the best mode presently contemplated by me for carrying out my invention:
Fig. 1 is a front elevation of a Ventilating device constructed in accordance with the instant invention;
Fig. 2 is a side elevation thereof;
Fig. 3 is a rear elevation thereof;
Fig. 4 is a section taken along line 4--4 of Fig. l; and
Fig. 5 is a side elevation of the wire mesh screen utilized in the instant invention.
Referring to the drawings, the Ventilating device comprises a cylindrical tube portion 12 and an end wall 14 having provided therein a plurality of louvers 16. End wall 14 has a radially extending marginal portion or flange 18 which is bent back upon itself as shown at 2t) and 22 whereby to integrally join with tube portion 12. As will be seen most clearly from Fig. 4, flange 18 is bent back upon itself in such a manner that portion 22 actually makes engagement with and abuts against said portion 18, or else so that it is in very closely spaced relation thereto.
As will be obvious, the louvers 16 extend downwardly whereby to act as a deterrent against the entry of rain, snow and the like, and while the device disclosed and illustrated embodies tive such louvers, it will be understood that a greater or lesser number may be utilized as desired and depending on the size of the device.
Referring now to Figs. 2 to 4, it will be noted that tube portion 12 is provided with a plurality of integrally struck detents. More specically, a plurality of outwardly extending detents 24 are provided adjacent the lower edge 26 of tube 12 in equi-spaced relation while a plurality of inwardly extending detents 28 are provided adjacent the flange 18, also in equi-spaced relation. As will be apparent from Fig. 3, detents 24 and 28 are staggered with respect to each other.
In order to prevent passage of bugs and insects and other undesirable foreign particles through the device, a wire mesh screen 30 is positioned and mounted just rearwardly of the louvers 16. The diameter of screen 30 is slightly larger than the inner diameter of tube 12 whereby it is adapted to be snugly received therein. Also, the screen 30 is domed as at 32, note Figs. 4 and S, for reasons now to be described.
In assembly, the screen 30 is forced into the tube 12 with its domed portion 32 foremost, whereby said domed portion will be in engagement with the rear of louvers 16. Meanwhile, the edges of the screen 30 will ride over and seat behind the inwardly extending detents 28, note Fig. 4, thereby maintaining the screen in operative position. Due to the domed configuration of screen 30, there will be no play between the rear surface of the louvers and the detents 28, thus the screen will be firmly held in place.
The simplicity of the above described screen mounting arrangement is thought to be apparent and the advantages emanating therefrom obvious. For example, should the screen become pitted or clogged, thereby impeding the flow of air therethrough, it can easily be removed for cleaning or replacement, without necessitating the removal or replacement of the unit itself. Also, should it ever become desirable to substitute either a finer or coarser screen, this likewise can be accomplished with a minimum of trouble and expense.
Although the Ventilating device 10 disclosed and illustrated herein is preferably formed from a single piece of thin, non-corrosive material, such as sheet aluminum or sheet copper, it will be understood that other suitable materials, such as synthetic resin plastic, may be utilized if desired. It will be further understood that instead of being integrally formed from a single piece of sheet stock, the device could be of a two-piece construction. Thus the end Wall 14 with its marginal portion 18 and louvers 16 could be formed from one piece of stock and then secured to outwardly extending flange 22 in any suitable manner.
The instant invention is of particular utility in ventilating small enclosed areas of houses and other buildings wherein moisture may accumulate with damaging eiects. Reference is made to enclosures such as the spaces between rafters, studding members and floor joists of buildings, which spaces are within the roof, wall and floor structures and hence are substantially closed. ln mounting the device, a bore 34 is provided in the building structure 36, which bore snugly receives the tube portion 12 in press-tit relation. As will be obvious, the outwardly extending detents 24 Will engage the surface of the bore to securely maintain the device in operative position. Flange 18 will overlie the building surface at the outer end of the bore, thereby preventing the device from being forced too far inwardly, while at the same time providing a finished appearance.
While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claim.
I claim:
A Ventilating device comprising a cylindrical tube portion open at one end and having a wall spanning the other end thereof, said wall having a peripheral marginal portion extending radially outward of the tube periphery, said wall further having a plurality of louvers therein, said tube portion having a plurality of peripherally spaced, outwardly extending detents located adjacent said open end and a plurality of peripherally spaced inwardly extending detents located adjacent said other end, and a whereby said screen is tightly retained in operative posiwire mesh screen positioned within said other end of said tion, although adapted vfor ready detachment. tube adjacent said louvers whereby to filter foreign particles from air passing therethrough, said screen being References Cited inthe me of this Patent domed whereby to insure that its peripheral edge` Will be 5 UNITED STATES PATENTS positionedrearwardly of said marginal portion in engagement with said inwardly extending detents while the cen 1,493,875 Ffedel'lck May 13, 1924 tral portion thereof makes engagement with said louvers,
