DETAILED DESCRIPTION

(8) FIG. 1 shows an exemplary laminated or tempered windshield 10, which may be suitable for use on UTV vehicles. The windshield 10 is shown with scallop cuts 12 on a lower edge. The scallop cuts 12 are positioned to receive the vent assembly 14 (FIG. 2) of the described embodiments, and the scallop cuts 12 are not limited to the lower edge of the windshield 10. Rather, the cuts 12 may be placed in the top and/or side edges of the windshield 10 depending on the application. The geometry of the scallop cuts 12 may be dictated by the equipment and process used by the glass manufacturer. FIG. 2 shows two vent assemblies 14 bonded to the windshield adjacent the scallop cuts.

(9) FIG. 3 shows an outer view of the vent assembly 14, and FIG. 4 shows an inner view of the vent assembly 14. With reference to FIGS. 3 and 4, the vent assembly 14 includes a vent body 16 with a flap opening 18 and a bond channel 20. As shown in FIG. 4, the bond channel 20 extends along the top and sides of the vent body 16. In a preferred construction, the vent assembly 14 is secured over the scallop cuts 12 with an adhesive disposed in the bond channel 20. A vent flap 22 is pivotably secured in the flap opening 18 on a flap pivot 24 (FIGS. 5 and 6).

(10) FIGS. 5 and 6 are cross sectional views with the vent flap 18 in a closed position and an open position, respectively. An actuator 26 is coupled with the flap 22 via a bracket 27 and a roll pin 28. The actuator 26 includes a key 29, and the bracket 27 protrudes from an actuator side of the flap 22. The bracket 27 receives the key 29, the key 29 includes an opening 34 as shown, and the roll pin 28 extends across or through an opening 27a in the bracket 27 and is secured in the opening 34. In some embodiments, the roll pin 28 is a spring loaded roll pin that is held in place by expanding after being inserted into position. To displace the flap 22 from the closed position shown in FIG. 5 to the open position shown in FIG. 6, the actuator 26 is displaced linearly in a linear track defined by a tab 30. The actuator 26 includes a rail 32 that rides in the track defined by the tab 30.

(11) In comparing FIGS. 5 and 6, in the flap closed position shown in FIG. 5, the roll pin 28 is disposed on one side of the flap pivot 24, whereas in the flap open position (FIG. 6), the roll pin 28 is disposed on an opposite side of the flap pivot 24.

(12) The opening 34 in the actuator 26 may be an oblong hole 34 in which the roll pin 28 is disposed. The roll pin 28 thU.S. extends through the oblong hole 34 in the actuator 26 and through the opening in the bracket 27 protruding from the flap 22. The roll pin 28 is freely displaceable (up and down in FIGS. 5 and 6) in the oblong hole 34. With this construction, a lever arm between the actuator 26 and the roll pin 28 is longer in the open position than in the closed position (compare the dashed lines from an arbitrary fixed point on the actuator to the roll pin in FIGS. 5 and 6). This structure results in a “snap” open condition when opening the flap and a “snap” closed condition when closing the flap.

(13) The linear displacement of the actuator 26 is facilitated by the oblong hole 34. That is, as the actuator 26 is pushed linearly forward, the vent flap 22 is pivoted on the flap pivot 24 thereby raising the roll pin 28 relative to the actuator 26. Compare, for example, a position of the roll pin 28 in FIGS. 5 and 6. The oblong hole 34 accommodates the vertical displacement of the roll pin 28, and as a consequence, the actuator 26 is linearly displaceable.

(14) With continued reference to FIGS. 5 and 6, the flap 22 is preferably configured such that in the flap closed position (FIG. 5), airflow urges the flap 22 toward the flap closed position. In the flap open position (FIG. 6), airflow urges the flap toward the flap open position. This configuration may be achieved by the angle of the flap 22 in the open position relative to a travel direction such that airflow strikes an underside or backside of the flap 22 to urge the flap 22 to maintain the open position. Alternatively or additionally, the flap 22 may be provided with an angled section 38 at a distal end relative to the flap pivot 24 as shown in FIG. 6.

(15) The roll pin actuation of the flap 22 is situated near the flap pivot 24, resulting in the snap open condition (i.e., the flap action is amplified with respect to the actuator action). To close the vent, the operator pulls on the actuator 26, which then pulls the vent flap 22 into the closed position. The roll pin actuation of the flap is similarly situated near the flap pivot, resulting the snap closed condition (i.e., the flap action is amplified with respect to the actuator action).

(16) With the windshield and vent assembly according to the described embodiments, outside air can be selectively directed through the windshield into the passenger cabin. The vent assembly can be secured to scallops cuts in a laminated or tempered windshield with an adhesive. Although the vent assembly has been described in the context of a UTV vehicle, the vent assembly is equally applicable to other vehicle types, and the invention is not meant to be limited to the described application.

(17) While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
