Description

A vwINDow VENTILATOR Filed July 19. 1940 Patented Sept. 8, 1942 UNTED STATES ATET OFFICE.
WINDOW VENTILATOR Truman L. Atkinson, Luding'ton, Mich.
Application July 19, 1940, Serial No. 346,294
This invention relates to window ventilators and is particularly adapted for use with ventilators of the extensible type which are provided with interlocking portions which may be slidable relative to each other and extended to t any size window.
The invention here is especially directed to novel means which not only act as antl-rattlers but also serve as stop means whereby the distance that the members may be extended is limited. In general I provide an elongated covered slot or recess in the outer member and one or more outwardly struck tongues on the inner member. The tongues have sufficient resiliency therein to force the inner member against flanges on the outer member during any of the intermediate positions of the members to thereby prevent rattling thereof, but when the two members are extended to their full-length position, the tongues are adapted to enter the recesses in the outer member to thereby prevent any further extension thereof.
To the accomplishment of the foregoing and related ends said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.
The annexed drawing and following description set forth in detail certain means and one mode for carrying out my invention, said means constituting, however, but one of various ways in which the principle of my invention may be employed.
In said annexed drawing, wherein like reference numerals refer to like parts throughout the various views:
Fig. 1 is a perspective view of an extensible window ventilator in one of its intermediate positions embodying my invention.
Fig. 2 is a vertical section therethrough.
Fig. 3 is an enlarged fragmentary rear elevational view thereof.
Fig. 4 is a fragmentary longitudinal section showing the two members in fully extended position and disclosing one of the tongues and recesses cooperating to act as stop means.
Fig. 5 is a view similar to Fig. 4 but sh-owing the two members in an intermediate position wherein the tongue is acting as an anti-rattler.
Fig. 6 is a fragmentary perspective view of the two members separated, and
Fig. 7 is a section taken substantially on the plane of line 'i-l of Fig. 1 looking in the direction of the arrows.
Although the drawing and following description set forth my invention as particularly applied to a window ventilator comprising two eX- tensible sections, it is to be understood that my invention may be applied to other articles of manufacture of a similar nature or may be applied to articles having more than two interlocking extensible sections, without in any way departing from the spirit thereof.
Referring now more particularly to the draw ing, the extensible members comprising the ventilator include an outer and an inner member, the outer member being indicated by the numeral I and the inner member by the numeral 2. The outer member at its upper and lower sides is provided with flat portions 3 and 4 respectively at the front sides thereof, The portion 3 then extends rearwardly a distance as at 5, then again downwardly as at S to provide a channel Within which the inner member iS adapted to slide. The lower flat portion 4 of the outer member extends rearwardly and again upwardly as at I and 8 to provide a similar channel member at the lower edge thereof. Between the upper and lower portions 3 and 4 of the upper member the louvers 9 are located which provide ventilation.
The inner member 2 is of a similar contour as the outer member I, being provided at its front side with the upper and lower flat portions I0 and II respectively. The -portion I'Il at its upper edge extends rearwardly for a distance as at I2 and again downwardly as at I3 while the lower portion II has rearwardly and upwardly extending portions I4 and I5. The channels thus formed at the upper and lower sides of the inner members 2 are slightly smaller than the upper and lower channels of the member 4I and are adapted to slide therein. The inner member 2 is also provided with a plurality of louvers I6 between the upper and lower sides thereof for Ventilating purposes. The outer ends of each of the members are provided with rearwardly extending portions II to thereby provide a closed end and limit the inward movement of the two members.
Adjacent the inner end of the outer member and located on the flat portions 3 and 4 thereof are located the outwardly extending portions I8 which act as cover members for the openings thereunder. These covers are struck outwardly from the portions 3 and 4. Adjacent the inner end of the inner member 2 and located on the upper and lower flat portions I0 and II thereof the tongues I9 are struck outwardly in the manner clearly shown in Fig. 6 and are of a size which will fit within the recesses covered by the portions I8 in the outer member I. When the two members I' and 2 are in operative position and slidably mounted with respect to each other, the tongues I9 will bear against the inner sides of the flat portions 3 and 4 on the outer member to thereby force the inner member rearwardly, whereby a snug it will be maintained between the upper and lower channels of the two members. This snug iit which results from the contact of the tongues I9 against the inner side of the outer member will thereby prevent any rattling of the two members which may otherwise be caused by the wind and the like.
When the inner member 2 has been extended a sufficient distance, the tongues I9 will then enter the recesses covered by the portions I8 and prevent any further extension of said member thereby limiting the outward movement thereof.
I also provide additional novel means for stiffening the entire frame of each member which includes the substantially triangular indented portions 20 in each corner. The inwardly diverging sides 2I of each of these portions begin in the extreme corner in the same vertical plane With the portions 3 and 4 on one member and I0 and II on the other member and then extend inwardly and rearwardly to terminate in the plane of the rest of the frame member. By this construction the sides 2| are also substantially triangular and aid materially in forming a more rigid structure.
From the above description it will be apparent that I have provided novel means on extensible window ventilators which have the dual purpose of not only acting as anti-rattlers but also as stop means to limit the outward movement or extension of the two members. The invention is economical to manufacture, easy to operate and has enjoyed success on the market.
Other modes of applying the principle of m invention may be employed instead of the one here explained, change being made with regard to the mechanism herein disclosed provided, however, that the means stated by any of the following claims or the equivalent of such stated means be employed.
I, therefore, particularly point out and distinctly claim as my invention:
1. A window ventilator comprising, a frame, a body integral with said frame and located in a diiferent plane therefrom, and stiffening means including an indented portion extending from a corner of the frame inwardly to the adjacent corner of the body, said indented portion being substantially triangular and the sides thereof diverging inwardly.
2. A window ventilator comprising, a frame, a body integral with said frame and located in a different plane therefrom, and stiiening means including an indented portion extending from a corner of the frame inwardly to the adjacent corner of the body, said indented portion having substantially triangular shaped sides which diverge inwardly.
3. A window ventilator comprising in combination, a plurality of extensible interlocking ventilating members, outwardly extending tongues adjacent one end of one of said members, and means on the other of said members adapted to receive said tongues when the members are extended to thereby limit the extension thereof, said tongues also forcing said members apart in their intermediate positions to thereby prevent rattling thereof.
4. A window ventilator comprising, inner and outer interlocking ventilator members adapted to be extended with respect to each other, tongues extending outwardly from the inner member, and openings in said outer member adapted to receive said tongues when said members are extended to thereby limit the extension thereof, said tongues also acting to force said members apart to prevent rattling when the members are in any intermediate position.
