1 Claim.

This invention relates generally to ventilator windows and refers more particularly to improvements in ventilator window assemblies of the type installed on vehicle bodies.

. Vehicle body ventilator window assemblies usually have a main frame divided into two areas or sections by a vertical bar and have a glass panel mounted in the rear section or area for vertical sliding movement. The front area is ordinarily occupied by a ventilator supported on the main frame for swinging movement about a generally vertical axis located between the front and rearedges of the ventilator.

It is customary to make provision for latching the ventilator in its closed position and for this purpose, a latch arm is usually pivoted on the bottom bar of the ventilator frame intermediate the ends of this bar. This location of the latch arm is not the most advantageous for convenience in operation by aperson seated in the vehicle immediately adjacent the window, and in any case, the arm usually projects inwardly some distance beyond the Window, where it is liable to catch or snag the clothing of the occupant seated adjacent the window.

With the above in view, this invention has as one of its objects to locate the latch arm on the front bar of the ventilator frame in advance of the axis of swinging movement of the ventilator in a position where it may be conveniently manipulated and, at the same time, is out of the way so that the danger of snagging or catching the occupants clothing on the operating handle is eliminated.

The foregoing as Well as other objects will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein:

Figure 1 is a fragmentary elevational view of a ventilator window constructed in accordance with this invention;

Figure 2 is a sectional view taken on the line 2 2 of Figure 1;

Figure 3 is a cross sectional view taken on the line 3-3 of Figure 1; and

Figure 4 is a cross sectional view taken on the line 4 4 of Figure 3.

In Figure l of the drawing there is illustrated a part of the vehicle body ventilator window comprising a main frame I0 defining a window opening and divided into two sections or areas by a vertical division bar II. The rear area or section is adapted to be closed by a glass panel I2 supported in any suitable manner for vertical sliding movement into and out of the area of the a keeper or cam plate 23.

Window opening in rear of the bar I I. The front section or area of the `window opening is occupied by a ventilator I3 supported in the main frame I0 for swinging movement about a genorally vertically extending axis I4 located between the front and rear edges of the ventilator.

The ventilator I3 comprises a glass panel I5 and a frame I6 which is usually substantially coextensive with the top, front and bottom edges of the panel I5. The top, front and bottom bars of the ventilator frame I6 are channel-shaped in cross section for receiving the adjacent marginal edge portions of the glass panel l5. As is usual with ventilator windows of the above geni eral type, the rear swinging edge of the panel I5 is adapted to abut a weather-strip (not shown) on the vertical division bar I I when the ventilator is in its closed position. Also, in accordance with convention practice, a flexible weather-strip I1 is secured to the main frame III around the ventilator I3 and is shaped to establish a weathertight seal between the ventilator and main frame when the ventilator is in its closed position.

In many types of ventilator window constructions, the iront bar I8 of the ventilator frame I6 and the corresponding bar of the main frame I0 are inclined rearwardly in the manner 'indicated in Figure l of the drawing. The front bar I8 is pivoted intermediate the ends thereof to the adjacent bar of the main frame by a pivot I9 having its axis coincident with the axis I4 and the bottom bar of the ventilator frame is pivoted to the bottom bar of the main frame by a pivot 20 having its axis also coincident with the axis I4. The particular construction of the pivots employed forms no part of this invention, and

therefore. need not be described in detail herein. It will suffice to point out that the pivots are such as to permit swinging movement of the ventilator I3 about the axis I4, and that the pivot 20 is of the friction type adapted to hold the ventilator in any one of its selected adjusted positions.

The ventilator 'I3 is secured in its closed position by a latch 2| comprising a latch arm 22 and The arm 22 is rotatably supported at the inner side of the ventilator I3 on the front frame bar I8 in advance of the axis of swinging movement I4. For accomplishing this result, a bracket 24 is provided having a part 25 extending into the channel of the ventilator frame bar I8 and secured to the base of the channel by a suitable rivet 26 in the manner clearly indicated in Figure 3 of the drawing. The bracket 24 also has a cylindrical part 21 which extends laterally inwardly from the 3 part 25 through a suitable slot formed in the inner flange of the channel-shaped frame bar I8.

The latch arm 22 is provided with a hub 28 rotatably supported on the cylindrical part 21 of the bracket 24, and is secured to the latter by a threaded stud 29. The stud 29 extends coaxially with respect to the cylindrical part 21 and the end of the hub 28 is apertur'ed to freely receive the stud. Thus while the stud 29 secures the latch arrn to the bracket 24, it nevertheless permits rotation of the arm 22 relative to the bracket 2. In addition to the hub 28, the latch arm 22 is also formed with an operating handlell and a projection 3 I which extezi'dsmfro'm UhbhZB at right angles to the operatinglia;ridlew,3 0,A ,flfhe arrangement is such that when the'ventilator it is in its closed position and the latch 'arm 22 is rotated to the position shown in Figurewl wherein the operating handle overlies the ventilating ltrarne bar i8, the projection `Ttengages the earn plane 23`an'd` secures the ventilator .in'ts closedposition, In this cnnection attention is again directed to Figure 3 of the drawing, Wherein' it will b'e noted that the cam plate cr keeper 23 is "sc-'cured tothe base the channel-shaped iront bar on the main frame Il?, and has a cam perdon whicnexten'ds `rnmrnly te a position for engagement with the projection` 3l 'on the latch arm 242. p t y t The 'extent of rotation of the latch arm to its cperativ'eland released positions is determined by lugs 33 and '3Q respectively secured to the bracket 213 and latchyarnll 22. lThe lug 33 extends axially inwardly from the cylindrical part 21 on Athe bracket, and the 34 extends radially inwardly fro-n1 the inner surface of Ithe hub` 218 on theY latch arrn. Thelolclatio'n of lugs is such as to locate the arm 22 in its latched position with the operating handle cverlying the inner side of the front frame bar I8 on the ventilator.

Thus the operating handle is not only rendered less conspicuous, but is located in a position where it is less likely to catch or snag on the clothing of a person seated immediately adjacent the window.

What we claim as our invention is:

A ventilator'l window comprising a main frame, a ventilator supported in the main `frame for swinging mvnient about an up and down axis located between the front and rear edges of the ventilator, a frame for the ventilator having a bottom bar and having a rearwardly opening channel shaped front bar inclined rearwardly `from the bott'oin a bracket having a part pdsitioned withi'rutlie channel oi the front ventilator fame bar and secured to the base of said channel intermediate the ends of the front ventilater; frame bar, said bracket having another part extending laterally inwardly with respect to the ventilator through an opening in the inner iiange of the channel shaped iront baixa latch arni rotatably supported on the inwardly extending part, and a keeper oi' thelrnfainframe adjacent the latch arm and englagefablfe with said arm-'upon rotation oi the latter to one position for securing the ventilatcr in its closed position in said main iran'ie.
