Application 'July 24, 1947, Serial No. 763,179

My invention is an improvement in the door. construction of motor vehicles, especially of that modern type of passenger automobile, of the coupe or other models, provided with wide door openings. r V

In such vehicles, the usual outwardly swinging single door is a source of trouble and risk upon opening, due to extreme extension of the door laterally, especially in crowded trafiic. Y

,Also, the tendencyof the door to swing backwardly, either, on a level or sloping highway, is a well known detriment, in connection with either incoming or outgoing pasengers.

My invention has in'view to greatly reduce the door opening by making the door of two hinged sections, and providing means for opening and closing them together by the usual familiar handle unlocking operation.

Also of assistance, the present construction involves coroperating automatic resistance means for preventing inward swinging or closing, as hereinafter described,

Neither of such'provisions are broadly new, per

se, and various prior constructions have been heretofore known, disclosing various forms of double doors, and also for holding the door open.

"My invention meets these problems in a satisfactory, eflicient, and novel'manner, as presented herein? 7 V.

In the drawings showing certain preferred constructions:

Fig. 1 is a, partial view in side elevation showing the door of an automobile, as closed.

Fig. 2 is a horizontal section on the line IIII of Fig. 1, showing the double doors as closed.

Fig. 3 is a vertical section on the line III-III of Fig.1. 1

Fig. 4 is a horizontal section on the line IVIV of Fig. 1;'showing the double door sections collapsed, and extended, as when finally opened.

Fig.6 is a vertical section onthe line V-V of Fig. 4. I

Fig. 6 is a horizontal section like Fig. 2, showing a modified construction, with the doors closed.

Fig. 7 is a similar'view showing the doors c01- lapsed, and open at approximately right angles to the body of the car.

Fig. 8 is. a similar partial detail view showing the double door in an intermediate position.

The main body of the automobile A, of any suitable or standard construction, is provided, usually at opposite sides, with an approximately rectangular entrance and exit opening within the edge portions, generally. indicated at a.

Inthe case of a, low sloping .portion, at rear or front, the edge opening, at either end, may be slopingly disposed, as at a.

The compounddoor member consists ofa'front Claims. (oi. 160-206) 2 or end portion member B, and a companion section C, hinged together by hinges 2, while one end section, as B, is similarly connected with a vertical frame member, such as a structural column 3. I

Door section C is provided with a locking and unlocking handle 4, on the outside and inside, of conventional type. Each of sections B and C is of usual rigid construction within the scope of vertical and upper and lower structural framing members 5, middle vertical pairs of such members being connected by the hinges 2.

Endmost member B is connected by suitable hinges 6 with column 3 for swinging it and member C outwardly or inwardly together, each having the usual outer thin metal sheathing l and the usual inner upholstery, not shown, but also conventional, as in Fig. 2.

Underneath the outer edge of floor 8 is a longi- A tudinal clearance opening 9, along through which extends one or a pair of guide rods l0, suitably anchored at their ends, as at Illa. Slidably engaging such rod or rods is a door controlling carriage II, to which is pivotally connected, as by hinge l2, an arm I3. Such arm I3 is pivotally connected by its terminal, as at I l, with the terminal framing member 5, or otherwise, whereby to cause the door section C to swing inwardly on its hinges 2.

Thus, as the double door is swung outwardly,

upon opening, and front section B swings on its hinges 6, section C in following, will close on its hinges 2, toward section B.

As retained by arm l3 and slidin carriage II, section C will finally assume a side by side position with relation to section B, as in Fig. i.

As shown in Fig. 3, a reinforcing upper guide rail l5, of suitable form, as by an elongated offset portion of the roof, extends lengthwise above the door opening, and serves as a resisting trackway for section C in opening. The endmost framing column 5 of the free section is provided at its' u per corner portion with a roller l6, pivotally carried by stem l'l.

As the free section C, upon closing, with both sections tending to close together as in Fig. 7, carriage H is thrust forwardly, and arm l3 exerts an inward pulling pressure, tending to hold r'oller it against the surface of guide bar rail l5, for the main portion of its movement towards section B. Another advantage is that the door is maintained in position, and prevented from rubbing against any portion of the main frame.

There is shown in Figs. 6, 7 and 8, a generally similar construction in which the sliding carriage Ila is mounted for a more limited movement along a supporting rod lOa, suitably connected y its termi a as in i -,8.

riage lla is consider'ably shorter than that of carriage l I.

13a, it is preferably provided with a right and left hand thread turnbuckle I325, connecting (and sections of'the arm, as shown. i 'J e Between carriage I la anda resisting abutment fixture I8, is a coiled spring l9; subject to com 'pression as the doors are closed, with-inward movement of the carriage.

When the doors are released for opening, the

compressed spring imparts outward movement to carriage Haand with resulting inward tension.

as the door moves to and from its closed position,

the outer or free edge of the door sectionC will be restrained by the link 13 against substantial movement away from the door frame;
