HINGE Filed Feb. 17, 1936 5MM/map Patented Oct. 18, 1938 UNITED STATES PATENT OFFICE 3 Claims.
This invention relates to hinges, and while the hinge is particularly adapted for use to mount the door of. an automobile, it is to be understood that it may be used for mounting any door or 5 other swinging closure.
One object of the invention is to s form the hinge that it will be countersunk between the door and door frame when the door is closed and thus be inconspicuous and not detract from the appearance of the automobile.
Another object of the invention is to so form the leaf which is secured to the door that the door when closed will have its outer face flush with the outer face of the wall of an automobile and when opened may be freely swung to a fully open position in which it will be out of the way and not interfere with a person stepping into or out of the automobile.
Another object of the invention is to provide a hinge having wall and door engaging members formed of strong sheet metal and of simple construction and very strong and durable.
The invention is illustrated in the accompanying drawing, wherein Figure 1 is a perspective View showing a portion of a door mounted by a hinge constructed in accordance with this invention, the door being shown in an open position.
Figure 2 is a sectional View taken along the line 2 2 of Figure 1.
Figure 3 is a View similar to Figure 2 with the door closed.
Figure 4 is a view looking at the outer faces of a door and a portion of a wall of an automobile with the door mounted by a hinge of the improved construction.
Figure 5 is a View similar to Figure 2 illustrating a modified construction.
The door, indicated in general by the numeral I, is of a conventional construction and is to be hinged to the wall or frame 2 of an automobile having a doorway to be closed by the door I. The improved hinge, by means of which the door is mounted for swinging movement into and out of a closed position, is formed of sheet metal of. sufficient thickness to impart desired strength to the parts and consists, briefly, of a bracket 3 carried by the wall or door frame and a leaf 4 pivoted to the bracket and secured to the door. The sheet metal blank from which the bracket is formed is stamped to provide tongues which are bent to form arms 5 of a length and width to extend into a recess or pocket 6 formed in the wall or door frame in flat contacting engagement with the recess and end portions of the bracket are formed with countersunk openings throughl which screws 'I are passed to firmly hold the bracket in place. It will thus be seen that the bracket may be set into a recess or hinge seat 8 formed in the edge face of the wall or door frame with the outer face of the bracket flush with the said edge face and as the openings through which the screws 'I' pass are countersunk, the heads of the screws will be flush with the outer face of the bracket. It will thus be seen that no parts of the bracket or screws will project beyond the edge face of the Wall or door frame and, therefore, the door may have close fitting engagement with the wall or door frame when closed, as shown in Figure 3.
The leaf 4 which is also formed of strong sheet metal has one marginal portion rolled to form a sleeve 9 through which a pivot pin I0 passes, and referring to Figure 4 it will be seen that ends of the pin project from the sleeve into openings II formed in the arms or ears 5 Where they are rmly secured by welding so that the pin will be held stationary and prevented from turning with the leaf or slipping out of. place. An opening l2 is formed adjacent the upperend of the sleeve in order that oil may be applied and thus lubricate the pin and interior of the sleeve and cause the sleeve to turn easily about the pin. Intermediate its width the leaf 4 is bent to provide an end portion I3 disposed in diverging relation to the remaining portion of the leaf and adapted to iit flat against the edge face of the door Where it is secured in a seat or recess I4 by rivets or other suitable fasteners I5. By so bending the leaf, the portion thereof between the end portion I3 and the sleeve 9 will extend diagonally in the recess or pocket 6 formed in the door frame or wall 2 when the door is closed and when the door is opened the leaf will swing from the position shown in Figure 3 to that shown in Figure 2. Therefore, the door may be swung to a fully open position where it will be disposed entirely to one side of the doorway and not interfere with a person stepping into or out of an automobile. A hinge so formed will be very strong and consist of a minimum number of parts which will not be liable to break.
In Figure 5 there has been illustrated a modiiied form of hinge. In this embodiment of the invention, the bracket or mounting plate I6 when cut to provide the arms I1 corresponding to the arms 5 is so cut that the intermediate portion of this mounting plate provides a resilient tongue I8 which is bent to project into the recess or pocket I9 formed in the door frame 20. The leaf 2| which corresponds to the leaf 4 is bent in spaced relation to its ends to provide an attaching portion 22 corresponding to the attaching portion I3 and openings are formed in this attaching portion to receive the rivets 23 by means of which it is secured against the edge face of the door 24. The other end portion of the metal plate from which the leaf 2| is formed is rolled to provide a sleeve 25 corresponding to the sleeve 9 and of a diameter to receive the mounting pin 26 carried by the arms l1. In spaced relation to ends of the sleeve 25 it is cut to provide a tongue which is bent outwardly and curvedto form a semi-circular arm 21 defining a pocket in which a rubber bumper 28 fits. This bumper has its end portions enlarged to provide heads 29 which bear against upper and lower ends of the arm 21 and serve collectively to prevent the bumper from sliding vertically out of its proper position within the pocket defined by the arm. When the door is closed, the arm 21 and the bumper carried thereby are disposed near the open outer end of the pocket I9 and the portion of the leaf 2I which extends diagonally from the door has face to face engagement with the resilient tongue I8. When the door is open, the arm 21 swings inwardly about the pivot pin with the sleeve 25 and finally moves to a position in which the bumper will engage the free end of the tongue I8 and limit movement of the door in an opening direction. Therefore, marring of the door frame by the door will be prevented. The fact that the bumper fits snugly into the pocket defined by the arm 21 and is formed with the heads 29 at its ends firmly holds it in place and prevents it from moving either longitudinally or transversely out of the pocket.
Having thus described the invention, what is claimed as new is:
1. A hinge comprising a bracket defining a face plate adapted to be secured against a door frame and having arms extending from the face plate adjacent opposite ends thereof and a tongue extending from the face plate between the arms, a leaf fitting between the arms and having a sleeve at its inner end, the outer portion of said leaf being adapted to be secured against a door, a pivot pin carried by the arms of said face plate and extending through the sleeve to pivotally mount the leaf, a tongue extending outwardly from the sleeve and defining a pocket having a longitudinally extending opening along one side, and a bumper mounted in said pocket with a portion exposed through the opening thereof for engagement by the tongue of the face plate to limit opening movement of the door.
2. A hinge comprising a bracket adapted to be secured against a door frame and formed with a cut-out for registering with a recess in the door frame, a resilient tongue carried by said bracket at one side of said cut-out and extending diagonally from the inner face of the bracket into the recess of the door frame, a leaf having companion side portions, one side portion of said leaf being adapted to be secured against the inner side edge of a door with the other side portion of the leaf extending diagonally from the door in overlapping relation to the inner side edge thereof and through the cut-out of the bracket into the recess of the door frame, and means for pivotally connecting the second-mentioned side portion of said leaf with said bracket to mount the leaf for swinging movement, said tongue constituting an abutment disposed in position to have face to face engagement with the secondmentioned side portion of the leaf and limit swinging movement of the leaf and a door.
3. A hinge comprising a door frame engaging member adapted to be secured against a door f frame adjacent a recess in the door frame, a resilient tongue extending diagonally from the said member into the recess of the door frame, a leaf having companion side portions, one side portion being adapted to be secured to a door
