The present invention relates to concealed hingel structures, and more particularly, to hinges for motor vehicle doors.

The primary object of the invention is to provide a concealed hinge structure of the abovementioned type which may be securely and rigidly attached to lone of the upright framev members of the vehicle body in such a manner as to prevent the inertia of .the'door when reaching its limiting point from bending or otherwise distorting the hinge structure and body structure of the vehicle.

Another object of the invention is to provide av hinge structure of the above-mentioned type comprising a comparatively small number of parts to become disorganized and to `provide a hinge which maybe quickly and easily constructed from blank stampings which likewise may be quickly and easily produced.

Another object of the invention is to providea concealed hinge structure of the above-mentionedl charact-er in which the box portion of the con--l cealed hinge may be quickly and readily attached to the frame structure of the vehicle sov as to form` an integral part of the frame structure and thereby prevent the weight of the doorV from causing the hinge to distort and' sag the door and genfl erally provide a concealed hinge structure whichv is rigid-and stable. Y Another object of the invention is to provide a concealed hinge structure of the above-mentioned v mounted to swing between a pair of parallel.

members which frictionally engage the Vhinge strap to retard the same and perform the function of a snubber and thereby prevent the doorv from being swung at a fast rate of speed during the opening movement thereof and causing damage to the frame of the vehicle and hinge structure.

Another object of the invention is to providea.

concealed hinge structure for motor vehicle doors in which the parallel side members of the hinge' box are connected at one end by a `reeniorcing strap so arranged with its ends overlapping the zclaimsf (ci. itiss). y f

provide additional support for the hinge pintle and` to facilitate attachment of the box-like hinge.: member to the vertical frame member or pillarof :a-vehiele and by welding said strap or otherwise aflxing the same to one of the flanges of said frame member or pillar.

Another Kobject of the invention is to provide a concealed hinge structure of the above-mentioned typev in; which the base portion of the box-like hinge member is slotted adjacent one end to provide ak tab projection adapted to be return bent over one of the edges ofthe vertical frame memp following description of the accompanying draw-v ing, 'whereinz .Figure 1- is` a horizontal cross sectional view through .a motor vehicle body structure illustrating an embodiment of the invention as ap-f plied thereto and showing the motor vehicle door swun'g'to an open position in dotted lines;

Adjacent one end of the spaced walls 63 is formed a pair of aligned openings 64 for receiving a hinge pintle extending through the eye of a hinge strap.

Interconnecting the spaced parallel side walls 63 at one end thereof is a strap 65 which is formed of metal and is similar to the strap 42 and backing member 53 in the forms of the invention shown in Figures 1 to 7 inclusive. The strap is provided with angular end portions 66 which are adapted to overlie and overlap the spaced side walls 63 so that openings 61 in the ends thereof will register with the openings 64 and receive the ends of the hinge pintle, in substantially the same manner as the overlapping ends 43 and 54 of the strap 42 and backing member 53. The intermediate portion of the strap 65 is cut out as at 68 to provide an anchoring lug 69 adapted to enter the slot in the flange il of said pillar post I0 so as to securely anchor the box-like hinge member 6| in place. the remaining portion of the strap 65 may be welded in place to the inner surface of the flange H of said pillar post.

In each of the forms of the invention it may be desired to weld the strap 42, backing member 53 or strap 65 to the inner surface of the flange i l' in lieu of the anchoring lugs, or if desired, the anchoring lugs may have their free ends welded in placeto integrate the structure and form a more rigid and solid construction.

It is to bev understood that the forms of the invention herewith shown and described, are to be taken as preferred embodiments of the same and that various changes may be made inthe shape, size and arrangement of parts without departing from the spirit of the invention or the scope of the subjoined claims.
