This invention relates to ventilating windows and refers more particularly to windows of this type designed for use in connection with vehicle bodies.

Ventilator windows of the type to which this invention pertains usually comprise a main frame adapted to fit in a window opening and a ventilator supported in the main frame for Swinging movement about a generally'vertical axis located between the front and rear edges of the ventilator. In one popular construction of ventilator window assembly, the bottom pivot is of the friction type adapted to resist swinging movement of the ventilator with sufficient force to insure holdingthe ventilator in any desired open position. Due to faulty assembly or inaccuracies that sometimes occur in mass production, the bottom pivot is not always precisely aligned with the top pivot and such a condition tends to produce a binding of the parts which increases the force required to manipulate the ventilator.

In order to overcome the above objection, the present invention has for one of its objects to provide, in effect, a floating friction pivot enabling the latter to adjust itself withrespect to the cooperating" pivot and thereby compensate for any misalignment that may exist between the pivots.

Another feature of this invention is to provide a ventilator assembly wherein the construction thereof is actually simplified by the design of the friction pivotv and assembly of the parts may be accomplishedmore readily.

.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 l is a fragmentary side elevational view of a ventilator-window assembly embodying the features of this invention;

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

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

Figure 4 is a fragmentary perspective view of a part of the friction pivot assembly employed in the ventilator window.

In Figure l of the drawing, there is illustrated a part of a vehicle body ventilator window I!) comprising a main frame II and a ventilator I2 supported in the main frame for swinging movement about an up and down axis indicated generally by the numeral I3. The main frame II is substantially channel-shaped in cross section and is constructed with the channel opening inwardly 7 Claims. (01. 296-44) with respect to the window opening. The usual flexible sealing strip I4 is secured in the channel of the main frame I Ixand cooperates with the ventilator in the closed position of the latter to form a weather-tight seal around the same.

The ventilator I2 comprises a frame I8: also channel-shaped in cross section and constructed so. that the channel opens inwardly with respect to the window opening. -A glass panel I 9 is supported in the frame I8 with themarginal edges projecting into the channel of thetframe I8 in the usual manner.

In accordance with conventional practice, a journal or bushing 20 is suitably secured to the outer side of the front bar of the ventilator frame I8. adjacent the top of the latter for receiving a pivot pin 2| suitably secured to the adjacent bar of the main frame II. The bottom bar 22 of the ventilator frame It is pivoted intermediate the ends thereof on the bottom bar. of the main frame II by a friction .type pivot assembly 23 having its axis of pivotal movement aligned with the pivot pin 2| to enable swinging the ventilator I2 to open and closed positions relative to the main frame I I.

In accordance with the present invention the ventilator I2 is held in any one of its various open positions by the action of the friction type-pivot assembly 23. In detail this assembly comprises .a pivot pin 24 which extends downwardly through the opening'formed in the base of the channel bar 22 and is formed with a laterally extending projection 25 at the upper end. The projection 25 is seated in the channel of the bar 22 below the adj acent' edge of the glass panel I9-and is riveted or otherwise permanently secured to the base of this channel. As best shown in Figure 1 of the drawing, theshank of the pin 24 extends downwardly through a suitable opening formed in the adjacent portion of the sealing strip I 4 and projects through an opening 26 formed in the base of the bottomchannel 2] on the main frame II. The opening 26 is enlarged to provide sufficient clearance to enable lateral. shifting movement of the pin 24 relative to the main frame.

The pivot pin 24 is rotatably supported onthe main frame I I by a bracket 21' having a body portion spaced below the channelbar 2! and apertured to permit free passage of the pivot pin 24 therethrough. Suitable lugs 28 project upwardly from opposite ends of the bracket 2l and extend into the channel of the bar 21 through slots 29 formed in the base of the channel bar 21. The lugs 28'are transversely curved with respect to the direction of-length ofthe-ba r 2'! and engage opposite ends of the slots 29 in the manner indicated in Figure 3 to enable limited rocking movement of the bracket transversely of the bar 27. It will further be noted from Figure 1 of the drawing that the width of the slots 29 is greater than the Width of the lugs 28 to permit limited shifting movement of the bracket relative to the bar 2'! lengthwise of the latter. As will be presently set forth, the pin 24 is clamped to the bracket 21 for movement as a unit with the latter, and as a result, the pivot 24 adjusts itself to compensate for any misalignment of this pivot with the pin 2| that may be caused by inaccuracies in manufacture or faulty assembly.

It will further be noted from Figure 1 of the drawing that the portion of the pin 24 which extends through the body of the bracket 21 is formed with a series of circumferentially spaced splines 30 and a correspondingly splined member 3| is sleeved on the pin 24. The member 3| assumes a position above the body portion. of the bracket 2'! and has a bearing engagement with the top surface of the bracket. A cooperating member 32 is sleeved'on the pin 24 and assumes a position below the body portion of the bracket 21' in bearing engagement with the latter. The member 32 is splined to slidably engage the splines 30 on the pin 24, and like the member 3|, is held against rotation relative to the pin 24. The two cooperating members are held in clamping engagement'with opposite sides of the bracket 27' by means of a coil spring 33 surrounding the pin 24 below the member 32 with the upper end seated against the member 32 and with the lower end engaging an abutment 34 on the pin 24. The

abutment 34 is in the form of a nut threaded on the lower end of the pin and is adjusted to hold the coil spring under compression. Thus the coil spring not only serves to resist swinging movement of the ventilator with sufiicient force to hold the ventilator in any one of its adjusted positions, but also functions to hold the bracket in assembled relation with the bottom bar 21 on the main frame M. It will be observed from Figure l of the drawing that the spring 33 actually urgesthe bracket 21' upwardly with sufficient force to enable the lugs to project into the flexible seal l4, and this is advantageous since it prevents rattling of the parts without interfering with the adjustment of the bracket to align the axis of the pin 24 with the axis of the pivot pin 20.
