PATCH MULTIPLE-POSITION DooR 2 Sheets-Sheet 2 Filed Aug. 1o, 1962 INVENTOR .Zia/471% zc Z United States Patent O 3,266,733 MULTIPLE-PUSIHON Dfi-UR Edward Patch, Dearborn Heights, Mich., assigner to Evans Products Company, Plymouth, Mich., a corporation of Delaware Filed Aug. 1d, 1962, Ser. No. 216,134 Claims. (Cl. 98-9) The present invention relates to means for controlling the flow of air or the like and more particularly to an improved door and improved means for mounting it in a wall opening in a plurality of positions for controlling in various ways, the flow of air or the like through said opening.

It is an object of the present invention to provide an improved low controlling means of the ahove mentioned type which is simple in design, of durable construction, reliable and efficient in operation, which is easily adjusted between a plurality of flow controlling positions and which is economical to manufacture.

It is also an object of this invention to provide an improved ilow control means of the above mentioned type including a door which can be mounted to close an associated wall opening, in spaced parallel relation to said opening, or in a plurality of inclined positions relative to said opening.

Another object of the invention is to provide such a ilow control means including novel handle portions which also serve to overlie the wall adjacent the opening, in the inclined positions of the door relative to the opening.

Other and more detailed objects of the present invention will be apparent to those skilled in the art from a consideration of the following specilication, the appended claims and the accompanying drawings wherein:

FIGURE l is a side elevational view of an air flow type space heater for an automotive vehicle with parts broken away, and showing an embodiment of the means of the present invention for controlling the `flow of air or the like;

FIGURE 2 is an enlarged front elevational view of a portion of the structure illustrated in FIGURE l taken in the direction ofthe arrow A;

FIGURE 3 is a front elevational view similar to FIG- URE 2 showing the door removed;

FIGURE 4 is a broken enlarged elevational View taken from the interior of the heater shown in FIGURE l and substantially along the line ig- 4 thereof;

FIGURE 5 is a sectional view of the structure illustrated in FIGURE 4 taken substantially along the line 5-5 thereof; and

FIGURES 6, 7 and S are sectional views similar to FlGURE 5 showing alternate positions of the door.

Referring to the drawings, an automotive truck type heater is indicated by the numeral l@ and includes means (not shown) for supplying heated air to the upper casing portion l2 which includes a front wall llt provided with an inwardly offset wall portion le having a generally rectangular opening lll therein the upper and lower edges of which are provided with opposed notches 2li.

Mounted in the opening ld is a generally rectangular door 22 which in the preferred embodiment illustrated is formed of generally hat sheet metal with its upper and lower edge portions reversely turned and formed to provide flange portions 245 which serve as handle portions to facilitate movement of the door between the positions hereinafter described. For supporting the door 22 on the wall portion ld, the door carries a generally U-shaped supporting element Z6 the web portion 2S of which is secured to the door 22 by an attaching clip 3h which is spot welded to the web portion 28 and to the door 22.

The U-shaped support element 21o has a pair of spaced legs 32 each of which has the outer end portion formed to provide a notch 34. The legs 32 are of a. width adapted to be received in the notches Ztl at opposite sides of the opening l and the notches 3d are adapted to receive the Wall portion ld. The legs 32 also have portions 36 at their web portion connected ends adapted to be received in the notches Ztl and engage the wall portion 16 when the door 22 is in the closed position, as is clearly illustrated in FIGURE 5. The support element 26 is formed of spring strip material and it will be noted that in the door closed position of FlGURE 5 the legs 32 diverge from each other as shown. A gasket 38 is mounted on the wall portion lo around the opening 18 and cooperates with the door 22 in this closed position to provide a seal between the door 22; and the wall portion 16.

An operator by grasping the handle flanges 24 may pull the door 22 outwardly so that both of the notches 34 lit over the edge of the wall portion 16 to hold the door in the position illustrated in FIGURE 6. FIGURES 7 and 8 illustrate inclined positions in which the door may be mounted for directing the air upwardly and downwardly if desired.` It will be appreciated that if desired the hole T18 and door 22 may be square or have any other desired number of sides of equal length and the door may be inclined to direct air laterally toward any one of the sides.

While the improved means of the present invention for controlling the llow of air or the like have been illustrated and described herein as embodied in an air heater apparatus for automotive vehicles it will be readily appreciated that the improvements thereof may readily be employed Wherever the llow control provided thereby is desired.

What is claimed is:

l. Means for controlling the liow of air comprising a wall having an opening therein which is symmetrical about an axis in the plane thereof, a door adapted to close said opening and having a pair of spaced legs secured to and extending laterally therefrom at one side thereof and carried solely by said door, each of said legs having a free outer end, and cooperating means on said door and on said wall for selectively supporting said door on said wall in a rst position in which said door closes said opening, in a second position in which said door is disposed in spaced parallel relation to said opening, in a third position in which said door is inclined relative to said opening, and in a fourth position in which said door is oppositely inclined relative to said opening, said co-operating means including a notch portion on each of said legs, both of which are adapted to engage said Wall in said second position and one of which engages said wall in said third and fourth positions.

2. Means for controlling the flow of air comprising a wall having an opening therein which is symmetrical about an axis in the plane thereof, a door adapted to close said opening and having a pair of spaced legs secured to and extending laterally therefrom at one side thereof and carried solely by said door, each of said legs having a free outer end, each of said legs having lirst and second portions one of which is adjacent said free outer end and which portions are adapted to selectively engage said wall at the periphery of said opening for cooperation with said Wall in supporting said door thereon, said first portions when both engaged with said wall supporting said door in a position to close said opening, said second portions when both engaged with said wall supporting said door in spaced parallel relation to said opening, said. iirst portion of one of said legs and said second portion of the other of said legs when both engaged with said wall supporting said door in an inclined position relative to said opening, and said second portion of said one of said legs and said lirst portion of said other of said legs when both engaged with said wall supporting said door in an oppositely sloped inclined position relative to said opening, each of said second portions having a notch adapted to receivea portion of said Wall at the periphery of said opening. l 3.
