1 7 Claims. 1

The present invention relates to doors for motor vehicles and embodies, more specifically,

an improved form of folding door providing a minimum of obstruction when moved to its open More particularly, the invention relates to folding doors for use on motor vehicles wherein a plurality of door sections are provided which,

in a closed position, conform generally to the vide a vehicle door having a plurality of vertically spaced sections as well as a plurality of horizontally arranged sections, the vertically spaced sections'lying in intersecting planes.

A further object of the invention is to provide, in a door of the above character, connecting means to pivot the several section thereof together to provide a complete closure.

, Further objects of the invention will appear as it is described in greater detail in connection with the accompanying drawings, wherein Figure l is a view in front elevation showing a door constructed in accordance with the'present invention;

Figure 2 is an enlarged partial view in'section showing the structure by means of which the edge of the door remote from-the hinge is guided from open to closed positions;

Figure 3 is a view in end elevation showing the profile of the door and its relation to the vehicle step well;

Figure 4 is a view in section, taken on the line 4-4, of Figure 1, and looking; in the direction of the arrows, showing the yielding non-metallic hinge structure between the upper and lower door panels; Figure 5 is a top View of the door structure,

Referring to the above drawings, the side of a motor vehicle is illustrated at It, being the profile of the side curved outwardly in accordance with the side surface conformation of a vehicle body when streamlined on its sides. In order that the door may occupy a minimum of space exteriorly or interiorly of the vehicle and conform closely to the shape of the side wall of the vehicle, the door is formed with portions that lie in intersecting planes. For example, Figure 3 illustrates the profile of the door in which the lower upper sections generally at I2.

sections are illustrated generally at H, and the These sections are connected together at the intersections of the planes thereof by means of a yielding hinge connection l3. Within the vehicle body steps M are provided in a suitable step well, in accordance with standard vehicle practice.

In order that the door sections may occupy as little space as possible and project as little as possible from the side of the vehicle when open, the door structure is preferably formed of two doors i5 and I6, as illustrated in Figure 1. Inasmuch as the structure of the doors [5 and it are identical, only one of them need be described.

With reference to door I5, it willbe seen that it is formed of two upper sections i1 and I8, respectively, hinged together by a hinge I9, and

two lower sections 20 and 2| hinged together by means of a hinge 22.

Section I! is provided with hinged brackets 23, which are secured to an operating shaft 24, while section 20 is provided with similar hinge brackets 25, which are secured to an operating shaft 26. Shafts 24 and 26 lie in the planes of 1311811 351060- tive upper and lower door sections and are connected together by means of a universal joint v 2 1, shown in detail in Figure 6. Rotation of either shaft 24 or 26 about its axis thus rotates the other shaft about its axis, and the door sections I1 and 251 are thus swun upon the ax s of the respective shafts 24 and 26. Any suitable means (not shown) for opening and closing the doors may be connected to either of the shafts and preferably to the shaft 24.

A continuous flexible closure strip 28 is secured to the outer edge of the sections it and 2 l, the strip preferably being of flexible material to permit the relative motion between sections 15 and during rotationof the operating shafts 24 and 26. to secure the sections l5 and 2! together, and also serves as a gasket for sealing the door opening when the doors are in closed position.

The flexible material 28 thus serves In order that the remote edges of the sections l and 2| may be guided from the closed to the open position, as shown in Figure 5, a bracket 29 is secured to the upper and outer portion of the section I5. Bracket 29 is formed with a pivot shaft 36 upon which a guide roller 3| i journaled. Guide roller Si is received within a U-shaped track 32, secured to the upper face 3;3o'f the'door opening. In this fashion, when shaft 24 is operated to swing the door section I! into the open position, illustrated in Figure 5, the hinge connection I9 between door sections l5 and l 1 causes the guide roller 3! to move in the track 32 to turn the door section i5 into the op'en positihn il lus a trated in Figure 5, in which it lies ifia'plahe parallel to the plane of the door section IT I In order that a Weather-tight "connection may be preserved between the upper and lower door sections, the hinge connection l3 may consist er a flexible strip 34. This strip is illustrated in detail in Figure 4, and preferably is: formed of a yielding non metallic material such as rubber. The upper and lower extremities of the strip are received within clamp members 35 secured at "35 to the respective door sections. Clamp members 35 receive securing pistes 31 and carrying pins 38 which are received in suitably positioned apertures 39fadjacent the edges of the fleiiible strip 54. In this fashion the flexible strip 34 is inain= tainedin position regardless of the position of the door sections and, being flexible, permits the adjacent corners of the door sections to separate the necessary distance in swinging from the closed to the open position without impairing the weather tight' connection between the upper and lower sections.

While the invention has been described with reference to the specific structure illustrated in the accompanying drawings,- it is not to be limited save as defined in the appended claims.
