RAYMOND L. CARR, OF BOSTON, MASSACHUSETTS v j CONVERTIBLE BODY This invention relates to convertible bodies, and more particularly to an arrangement of closure members which are movable from, a lowered position within or adjoining the body wall to a'raised position thereabove to form a closure wall.

More particularly the present invention provides a plurality of closure members which may be carried by a single section of a body wall such as a door and which may be moved out of the same by a lifting mechanism to a raised position wherein they not only occupy a position directly above the body wall section but project beyond the *same to bridge the space over a structural part of the wall. Thus in accordance with the present invention, pivotaly mounted guid'eways preferably are movable from a loweredposition in which they extend along the top of the'body wall to a raised position wherein they are engaged by the edges of a vertically movable closure panel or panels, and a lifting mechanism ensures the location of the'guid eway or guideways in raised posi- -.(tion before the panel starts its upward movement into engagement with the same. Accordingly undue strain upon the pivotal mountings of the guideways is avoided such as otherwise might occur, either if the window lifter were thoughtlessly to be operated to start the panel upward upon its upward path with the guideways in their lowered positions, or if the guideways were to be swung toward their lowered positions when the panel is still in engagement with their lower ends, while the accidental slamming of the guideways downwardly from their raised to their lowered positions is also avoided. i i i In accordance with this invention, the swinging guideways preferably are provided with yieldable portions adaptedto engage adjoiningportions of the vehicle structure such, for example, as a similar guideway carried by another door. Thus the guideways are adapted to bridge the space over a door post or thelike and permit a closure wall to be provided by members which may 5 be'readily lowered into the side of the Preferably theconven tiona'l window or panel lifting mechanism is arranged to have a portion thereof follow a longer path than that required to lift the window so that at the lower end of its path it may be effective during its upward movement in lifting the guideways to .a raised position and during its downward movement in lowering the same. This avoids the necessity of fumbling with separates posts, stanchions, guideways, etc., and enhances the convenience of manipw. lation of the closure members, being particularly advantageous, for example, when the driver desires to lift or lower the adjoining window with the car in motion.

Further objects and advantageous features of the invention will be apparent to those skilled in the art upon a reading of the subjoined description and claims in conjunction with the accompanying drawing,in which Fig. 1 is an elevational view of a body section or door. with the inner wall thereof removed to show the panel-in its lowered' position and the guideways in raised position and with the board for supporting the lifter r Fig. 4 is an enlarged section on line 4-4 of Fig. 3; and

Fig. 5 is a section on line 5-5 of Fig. 1. In the accompanying drawing, the numeral 1 designates a section of the body wall of a vehicle which provides a pocket in which a While my invention may be employed with:

a -wide variety of window lifting mechanisms, I have shown herein a lifter 10 which comprises'a sector 11 having a toothed portion meshed with the pinion 12that is rotated by the usual hand crank 13 within the vehicle. The lifting arm 16 is secured to the sector and carries a roller 17 that is engageable with the frame of the lower portion of the panel. A suitable board 20, indicated by dot and dash lines, is arranged to support the pivotal mountings for the crank 13 and the sector 11. In accordance with the present invention the arm 16 and the sector 1.1 are arranged so that the former may swing downwardly to a position wherein the roller 17 is considerably spaced from the bottom of panel 1, as shown in Fig.

A swinging guideway 25 having a channeled portion may be disposed at one or both ends of the pocket 1. Each guideway preferably is pivotally mounted upon pins 26 that are carried by brackets 27 at the end of the door or body section. Preferably the pintles 26 are spaced downwardly and inwardly from the upper corners of the pockct and the body portion of each guideway 25 is offset inrelation to the same, being connected thereto by extension portions 28, thus permitting the guideway in its raised position, as shown in Fig. 1, to overhang the end of the pocket and, for example, to cooperate with a similar guideway carried by an adjoining body wall section or door to bridge the space over an intervening structural part of the body wall, such as a door post.

Fig. 4 illustrates a typical cross section of a guideway which is provided with side plates 29 and with a window engaging channel 30 which may be provided with flared edge portions 31. A suitable filler 32 may be dis posed between the plates :29 and ayieldable cushioning member 3 1 may be engaged between the plates 29 and rabbeted portions 33 of the filter. This cushioning member preferably comprises a semi-circular rubber element, as viewed in cross section and is somewhat deformable when the guideway engages an adjoining part of the vehicle, such as a portion of the windshield standard or another guideway or when the opening of the door necessitates relative movement between these parts, although the yieldability of this cushioning member is such that it ordinarily is effective in maintaining a substantially weather-tight seal between the guideway and adjoining structure.

In order to permit the lifter 10 to be effective in raising and lowering the guideways 125 and to avoid the attempted raising of the pan-' el when the latter are lowered as well as attempted lowering of the guideways when the panel is not entirely lowered, I preferably operatively connect the guideways to the lifting mechanism. For this purpose a double cam 40 is pivotally mounted upon a bracket 41 or the like in. the lower portion of the body wall pocket. The cam 40 is provided with angularly disposed cam surfaces 43 and 4 1 which are adapted to be engaged by the roller 17 at the end of the lifting arm 16. A link 45 is pivotally connected to a portion of the double cam and to a rotatable element 46 such as a disk which conveniently may be pivotally mounted upon the board 20 by means similar to that employed for the sector 11. The rotation of the double cam about its pivotal support results in the movement of the link 45 and consequently the pivotal movement of member 35. The latter is connected by

suitable links

50 and 51 to the lower portions, i. e. extensions 28, of the guideways 25.

As the lifting arm 16 of roller 17 moves up from its lowermost position, shown in Fig. 3, it engages the upper cam surface 1 1 of the member 10, swinging the latter to the position indicated in Fig. 1 wherein the roller is free to leave the cam member and to engage panel 2. During this portion of its path the roller 17 is effective through the cam 40, link 4-5, member 16, and links 5051 in swinging the guideways from their lowered positions, shown in Fig. 3, to their raised positions, shown in Fig. 1, wherein the channel portions 30 thereof are positioned above the channels 3 in the body wall and are ready to receive the edges of the closure panel. 2. Preferably a tension spring 56 connects the swinging cam with a portion of the door or the like, tending to swing the double cam to the position shown in Fig. 1 and thus aiding the lifting of the guideways.

It is obvious that as the lifter arm 16 continues upon its upward movement panel 2 will be lifted into engagement with the guideways 25. Similarly during the upper portion of its downward path the arm 16 first permits the panel 2 to be lowered until it en-t gages the bracket 6, whereupon the double cam 40 is swung downwardly toward the position illustrated in Fig. 3, thus being effective through the link 415 in rotating the member 46 and causing the

links

50 and 51 to swing the guideways to their lowered position wherein the channeled portions thereof may engage the upper edge of the lowered panel, which may act as a stop for the same.

The

links

50 and 51 may be comparatively light, somewhat resilient rods, the yieldability which permits slight inaccuracies in workmanship so that the exact positioning of the various centers and cam surfaces need not be accurately determined, the top of the body wall acting as a stop to position the guideways when they are raised, and the top of the panel 2 performing a similar function when they are lowered. Thus the member 46 ordinarily may have an angular movement slightly greater than is necessary to move the guideways, the

links

50 and 51 being slightly bowed at the end of this movement corresponding to the raised position of the guideways.

It is evident that the present invention affords means permitting the ready positioning of auxiliary closure members which preferablymay be guideways for the main panel but which, if desired, may be separate auxiliary panels or the like so that the closure wall over a door and an adjoining structural portion of the body may be readily formed by the manipulation of a single lifter and so that the tendency to throw undue strain upon the uideways by attempting to lift the panel be ore the guideways are raised by attempting to lower the guideways before the panel is fully lowered is avoided.
