Application March 6, 1935, Serial No. 9,634

s Claims. (ol. 16-163) This invention relates to hinges capable of general application but particularly designed for use on automobile doors. It is well known that the upper and lower hinges' on such doors are commonly spaced substantially apart and that the outer surfaces of the door and body are fre- '15 outside of the body and door surfaces. This construction, while effective; is ungainly, and the outwardly projecting hinge parts impair the beauty of the body design.

It is the general object of my present invention to provide an improved hinge which will project the door outward as it begins to open, and

which will be entirely concealed when the door is closed. y

A further object of the invention is to provide a concealed hinge which will rmly support a wide and heavy door without sagging or undesirable looseness in any position.

My invention-further relates to arrangements and combinations of parts which will be herein- 3o after described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawing, in which y Fig. 1 i's a sectional plan view of my improved hinge, together with portions of the associated door and body;

Fig. 2 is a view similar to Fig. 1 but showing a door and hinge in open position;

Fig. 3 is a front elevation of one of the hingev plates, looking in the direction of the arrow 3 in Fig. 1;

Fig. 4 is a similar view of the other hinge plate, looking in the direction of the arrow 4 in Fig. 1, and

Fig. 5 is a side elevation of one of the hinge links, looking in the direction of the arrow 5 in Fig. 1.

Referring to the drawing, I have shown a portion of a body B and a portion of a door D. The body B includes an outer metal casing or panel I0 having an inwardly olset corner portion or rabbet II which is thereafter extended ,inward to provide an edge portion I2. ,The casing or panel I0 is cut away along the edge I2 inside the door opening and along a portion of the corner or rabbet I I at the points where hinges are to be applied, and at each of these points the body is provided with a reenforcing plate or hinge support I3 which is rmly secured in some convenient manner, as by spot- 5 welding to some body part I5, such as pillar, panel reenforcement or bracket.

The reenforcing plate or hinge support I3 is provided with spaced elongated slots I4 for a purpose to be described.l Any suitable interior l0 finish of leather, bre, fabric or other material may be provided as indicated at I6.

The doorD is similarly formed with an outer panel 20 having a projecting portion 2| anged over the outwardly projecting edge portion 22 of 15 an inner casing or pillar 23. A portion 25 of the inner casing or pillar forms the edge of the door and connects the portions 22 and 23 previously described.

A reenforcing plate or hinge support 2B is pref- 20 erably secured to the edge portion 25 by spot-welding or otherwise, and the reenforcing plate 26 has an oiset portion 2l extending along the inner side of the door and having elongated spaced slots 28. 25

My improved hinge comprises hinge plates 30 and 3|, hinge links 32k and 33, land a plurality of hinge-pins 34, 35, 36 and 31.

The hinge plate 30 is provided with countersunk holes 40 to receive screws 4| (Fig. 1) extend- 30 ing through the slots I4 in the reenforcing plate or hinge support I3 and' threaded into a tapped plate 42 disposed at the rear of the reenforcing plate.

- Reference to Fig. 2 will show that the screws 4I 3s are readily accessible when the door is open, and that by loosening the screws 4| the hinge plate 30 may be adjusted transversely in the body B to cause the surfaces I0 and 20 of the body and door 40 to assume proper alignment.

Similarly, the hinge plate 3| is provided with countersunk holes 50 to receive screws 5I extending through the slots 28 in the reenforcing plate 26 and into a tapped plate 52. By loosening the screws 5|, the door D may be adjusted widthwise relative to the body B, thus permitting convenient centering of the dcorin the door opening.

The hinge plate 30 is provided with an oiset portion from which extend upper and lower 50 bearing members 6I and 62 which are provided with openings (i3L and 54 for the hinge-pins 34 and 36 respectively.

The hinge plate 3| is provided with outwardly projecting bearing members 'l0 having openings 1| and 12 for the hinge-pins 35 and 31 respectively.

It will be noted that the hinge-pins 34 and 36 are abruptly and substantially offset from the plane of the hinge-plate 30, while the hinge-pins 35 and 31 are only slightly out of alignment with the hinge-plate 3l.

It will be noted also that the hinge-pins 35 and 31 are substantially further apart than the hinge-pins 3B and 36 and that the link 33 is substantially longer than the linkv 32. `The link 32 is also substantially arched to provide a recess 15 for the end of the link 33 when the door is open, as indicated in Fig. 2, in which position the link 32 and the end of the link 33 cooperate to form a stop.

A packing 11 is preferably secured under the projecting portion 2l 'of the door casing 20, to form a windbreak as clearly shown in Figs. 1 and 2.

Hingesthus constructed possess very substantial and important advantages. Reference to Fig. 2 will show that the paths of swinging movement of the hinge-pins 35 and 31 do not at any point intersect, and that they are always substantially spaced apart so that the overhanging weight of the door is in all positions firmly supported. The door movement is also such that the overhanging edge portion 2i has no motion toward the interior of the car but remains substantially in one position during "th initial opening movement of the door and thereafter moves rapidly outward to the position shown in Fig. 2.

'The initial swinging movement of the door is substantially about the point X (Fig. l) near the end of the projecting portion 2l of the door and without perceptible movement of the door Widthwise or in the direction of the arrow a in Fig. 1. Consequently, there is no binding of the door during the initial opening movement;

, After the swinging edge of the door has cleared the door casing, the point X follows substantially the curved line d to the position indicated in Fig. 2, the path of movement approximating a hyperbolic spiral. It will be apparent that the edge of the extension 2i at all times substantially clears the outer casing l of the body, even in cases where the casing is substantially curved outward between the hinges.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:-

1. A concealed hinge comprising a ilrst hinge plate to be attached to a xed member, a second hinge plate to be attached to a swinging member, and longer and shorter hinge links connecting spaced bearing points on one hinge plate to spaced bearing points on the other hinge plate, the bearing points on said first hinge plate being" disposed in a line substantially inclined to the outer sur face of said swinging member when said member is in closed position, the bearing points on said second hinge plate being in a line nearly parallel to said outer surface, and the bearing points on said first hinge plate being substantially nearer together than the bearing points on said second hinge plate, the bearing point on said first hinge plate which' is more remote from the securing portion of said first hinge plate and the bearing point on said second hinge plate which is nearer the securing portion of said second hinge plate being connected by the longer link.

2. A concealed hinge comprising a first hinge plate to be attached to a fixed member, a second hinge plate to be attached to a swinging member, and longer and shorter hinge links connecting spaced bearing points on one hinge plate to spaced bearing points on the other hinge plate, the bearing points on said first hinge plate being disposed in a line substantially inclined to the bearing point on said second hinge plate which is nearer the securing portion of said second hinge plate being connected by the longer link, and said 'shorter link-being arched to provide a recessed portion at one side thereof to receive one end of said longer link, said recessed portion and said link end cooperating to form a stop when the swinging member is in open position.

3. A concealed hinge comprising a iirst hinge plate to be attached to a xed member, a second hinge plate to be attached to a swinging member, and longer and shorter hinge links connecting spaced bearing points on one hinge plate to spaced bearing points on the other hinge plate, said rst plate having a securing portion extending transversely of the outer surface of said fixed member, and said secondplate having a securing portion extending substantially parallel to said outer surface, and means to attach said securing portions to associated parts of said fixed and movable members, said attaching means comprising bolts extending through aligned openings in said securing portions and associated parts and certain of said openings being elongated, whereby each of said plates may be adjusted relative to its supporting structur'e in the plane of its securing portion and may be firmly securednin'selected adjusted position.
