(YO/ E6 507214? a United States Patent FDLDABLE WINDSHIELD FOR SPORTS CARS Gerald Charles Coker, Warwick, England, assignor to Donald Heaiey Motor Company Limited, Warwick, England Application April 24, 1953, Serial No. 350,888

Claims priority, application Great Britain October 15, 1952 7 Claims. (Cl. 296-84) This invention relates to a front windscreen of a motorcar or other motor-vehicle, of the kind which can be moved from its normal erected position to a substantially horizontal position in which it extends forwardly over and against the adjacent part of the hood or scuttle of the vehicle.

In the case of a flat windscreen pivotally mounted adjacent its lower edge, its ends, when the windscreen is in the substantially horizontal position, are usually well spaced above the adjacent part of the hood or scuttle, which latter is slightly curved transversely of the vehicle, being convex upwardly. This spacing would be greater still in the case of a curved windscreen or a V-shaped windscreen if it were pivotally mounted at its lower edge.

The main object of the invention is to enable a nonplanar windscreen (i. e., a curved or V-shaped windscreen) to be folded to a low sports position and at the same time to allow the curve of the glass substantially to match the contour of the adjacent part of the hood or scuttle upon which it rests.

The invention therefore relates to a non-planar windscreen; and, according to the invention, the erected windscreen has a locating engagement at its lower edge which does not however prevent the upward movement of the screen, the latter movement being prevented by means of pivotally-mounted arms at each end or upright edge of the screen, each of which arms has a slotted engagement at one of its pivotal points with a locking means.

Thus, to move the screen to a low sports position as aforesaid, the locking means are first released and the screen then pulled upwardly as necessary to free its lower edge from the said locating engagement, after which its lower edge can be moved forwardly whilst the two arms are swinging forwardly, the now forward edge of the screen finally having a rather similar locating engagement to that of the erected screen (but with brackets on the scuttle or hood) which is completed by the reoperation of the said locking means. The actual matching (i. e., the extent of the matching) will of course be dependent upon the transverse curvature of the scuttle and the curvature of the screen.

In the accompanying drawings:

Figure 1 is a side elevation of one of the side frame members of the windscreen, and the supporting base bracket, when the windscreen is erected;

Figure 2 is a sectional view showing the arm of that side frame member supported in a recess therein;

Figure 3 is a corresponding side elevation of the windscreen when lowered and locked in the lowered position;

Figure 4 is a fragmentary front elevation, to a larger scale, mainly of the side frame member of Figures 1 to 3, and

Figure 5 is a section to a smaller scale on the line 5-5 of Figure 1.

In the construction shown, the locating engagement of the

lower edges

11, 12 of each of the side frame members 13 at the ends of the erected windscreen 13a takes the form, at each end, of

pins

14, 15 carried by the lower 7 2,716,041 Patented Aug. 23, 1955 ends of the side frame members, the axes of the pins being substantially parallel to the general plane of the windscreen. The pins engage in

corresponding holes

16, 17 provided in supporting base brackets 18 fast with the scuttle or equivalent part 19 which is rearwardly of the hood. The upper edges of the brackets 18 are stepped to coact with the

lower edges

11, 12 of the side frame members as shown most clearly in Figure 3. In side elevation, one of the pins 14 (at each side of the screen). is forwardly of and lower than the other pin 15. I

Each of the base brackets 18 provides a pivotal connection 20 for the adjacent arm 21, the pivotal axes being substantially horizontal and collinear and also below the higher pin 15. In the erected position each of the arms extends upwardly according to the inclination of the screen, as clearly shown by Figures 1 and-2. Each arm 21 is mounted in a recess 22 of the adjacent side frame member. 1 7 a Each of the locking means conveniently takes the form of a headed bolt 23 fast with the adjacent side frame member 13, and a nut 23a. In the erected position the bolts 23 lie at the inner (lower) ends of the slots 24' in theassociated arms, these slots being parallel axes.

The lower. edge of the screen is provided in a well understood manner with a rubber or like sealing fillet 25- to engage the adjacent surface of the scuttle or hood, as shown in Figure 4.

Tolower or fold the screen the two locking. nuts 23a are released and, together with the screen, liftedto carry the bolts to the outer ends of the slots 24 in the arms, thereby disengaging the

pins

14, 15 from their locating holes. Thereupon the screen can be swung into a generally-horizontal position with its lower edge forwardly, and the arms can be swung forwardly to carry the whole screen forwardly until one or more of the pins on each side of its now forward edge (e. g., the pins 14) engage corresponding locating holes provided for the purpose in brackets 27 fast with the adjacent portion of the scuttle or hood. Thereupon tightening the clamping nuts 23a will fully locate the screen in its lowered sports position, as shown by Figure 3, in which, in the case of an appropriately curved screen and hood or scuttle, the glass of the screen can match the contour of the scuttle.

For locating the locking bolts in their extreme positions, the arms are provided with recesses 29, 30 (Figure 4) for the heads 31 of the bolts.

Obviously, the reverse movement will be necessary again to locate the screen in its erected position.

As an obvious alternative the locating engagement can be effected, if preferred, by means of stationary pins at the respective places adapted to enter into holes provided for the purpose in the frame of the windscreen.

What I claim as my invention and desire to secure by Letters Patent of the United States is:

1. A motor-vehicle with a non-planar windscreen, said windscreen when in the erected position having at its upright edges side frame members, supporting base brackets for said side frame members, axially disconnectable pin and socket means interconnecting said side frame members and said brackets for holding said windscreen in an erected position, said pin and socket means being parallel with said side frame members when the windscreen is erect, arms hinged to said base brackets and having longitudinally directed slots at their free ends, said slots extending parallel to said pins and said arms being received in recesses in said side frame members when said windscreen is in erected position, and releasable locking means engaged with the lower ends of said slots when said windscreen is in erected position, said locking means, when released, permitting disengagement of said pin and socket to the pin means whereby the bottom edge of said windscreen and said arms can be'swung forwardly for said windscreen to be substantially horizontal with its top edge in a lowered operative position, said locking means then being engaged with the other 'end of said slots.

' 2. A motor vehicle having a windscreen according 'to claim 1, characterized in that the slots in said arms are sufliciently long so that when the locking means are released and moved to the other ends of said slots, said pin and socket means will be disengaged thereby allowing the lower edge of the windscreen to be turned to a forward position and the windscreen as a whole to be swung, whilst the arms move about their pivots, into a flat flowered position. 7 a 3. A motor vehicle having a windscreen according to claim 2, and having fixed brackets with sockets therein the pins are fast with the side frame members and the sockets are fast with a scuttle of the vehicle, one of the pins being at the bottom of each of said side frame members, a second socket means forwardly of said sockets and for engagement by the bottom pins to hold the windscreen in its forwardly swung position.

5. A motor-Vehicle having a non-planar windscreen with side frame members at its upright edges when in an erected position, base brackets for supporting the side frame members, axially disconnectable pin and socket means interconnecting the lower ends of said side frame members and said brackets for holding said windscreen in an erected position, said pin and socket means being parallel with said side frame memberswhen the windscreen is erect, arms interconnecting each side frame member and the adjacent base bracket by means of pivots to complete the location of the windscreen when erected, said arms having s'lots' therein for slotted engagementswiththe pivots at one end of each of said arms, and locking means associated with the pivots having the slotted engagements, said lockingmeans, when released, permitting disengagement of said pin and socket means whereby the bottom edge of said windscreen and said arms can be swung forwardly for said windscreen to be substantially horizontal with 'its top edge in a lowered operative position, said locking means then being I engaged with the other end of said slots.

6.
