Application May 2, 1932. Serial No. 608,640

5 Claims. I (Cl. 1613f5)- The invention relates to hinges, and has for an object the provision of a strong, durable. and

inexpensive'concealed door hinge adapted for use on. an automobile body, the construction be- 5 ing such as to minimize strains on the pintle, to avoid interference with weather flanges-on the door, and to reduce obstruction of the doorway when the door is open.

The invention further consists in the several features hereinaftersetforth and more particularly defined by the annexed claims.

In the accompanying drawing, Fig. 1 is'a fragmentary elevation of an automobile body embodying the hinge of the inventiomparts of the body being broken away and parts being shown in section;

Fig. 2 is a sectional view thereof the line 2-2 of Fig. 1;

Fig. 3 is a sectional view thereof taken along the line"33 of Fig. 1, the door being shown in open position;

Fig. 4 is a sectional view taken along the line 4-4 of Fig. 4, the door being in an intermediate position, and

Fig. 5 is a fragmentary sectional detail view of a stationary hinge member forming part of the hinge.

In this drawing, the numeral'lO designate a door post or jamb of an automobile body, and 11 a door occupying a doorway 12 in the body. The door post may be covered at its outerand inner sides by respective panels 13 and 14, and the door 11 may be similarly faced with outer and inner panels 15 and 16, respectively. The outer door panel 15 is provided with a weather flange 17 which overlies the edge of the body panel 13 when the door is closed, as seen in Fig. 2.

The door is supported by two or more hinges embodying the invention, one being shown. The door post 10 has a cavity 18 formed therein to receive a stationary hinge member 19 which is provided with upper and lower flanges 20 let into the door'post and 'secured thereto by screws 21.

45 The hinge member 19 includes spaced parallel cheeks 22"connected at portions remote from the flanges 20 by a wall 23 and forming therewith a recess 24 which opens at the doorway. ,The

wall 23 includes an angular portion 25 which at 50 its forward edge is provided with a hinge knuckle 26 disposed centrally between the cheeks 22.

A movable hinge member 27 has a curved hooked portion 28 provided with opposite parallel faces 29 slidably fitting between the cheeks 22 of the stationary hinge member. The hooked taken along portion 28 has a pair of spaced hinge knuckles 30 which fit between the knuckle 26 and the cheeks 22 and are secured thereto by a pintle 31. The pintle is arranged between the open front of the hinge member 19 and the rear wall 25 of this 0 hinge member, and is close to the wall 25, so as to provide rigidity and so that the knuckle 26 can be relatively short in radial direction. The

hinge member 27 carries a flange 32 which is let into the door and is secured thereto by screws 5 3 3. The flange 32 may be extended, as indicated, to form part of a similar hinge member of an 7 adjacent hinge, not shown, tofacilitate alignment. The stationary hinge members of the ad- .'iacent hingesmay be similarly connected.

When the door is closed the hinged edge of the door lis contiguous to or closely adjacent the edge of the door post 10, and the weather flange 17 lies close to the body panel 13. The inner edge of the hooked portion 28 of the movable hinge member is provided with a nose 28- which enters a recess 34 formed in the wall 23 of the stationary hinge member. The extreme opening movement of the door is limited, as seen in Fig.

3, by the engagement of the movable hinge member 27 with a pair of lugs 35 projecting from the cheeks 22 into the recess 24. between the cheeks. In the open position of the door, the hinge memher 27 extends only a small distance into the doorway and has no projections on which clothing will catch, and the open door does not appreciably reduce the effective width of the doorway. The recess 24 of the stationary hinge member is substantially concealed by the hook member 29 of the open door.

The inner faces of the cheeks 22 are provided with aligned arcuate grooves or tracks 36 concentric with the axis of the pintle 31. Balls 3'7 are loosely mounted in hemispherical pockets 38 formed in the opposite parallel faces 29 of the movable hinge member 27 and are movably mounted in the tracks 36. Grooves 39 are formed on the inner faces of the cheeks in communication with the grooves 36 to permit entry of the balls into the latter grooves when the hinge is assembled. The entry grooves 39 preferably extend from the inner ends of the grooves 36, as seen in Fig 3. The entry grooves may be omitted in some instances, especially when the hinge is constructed of sheet metal stampings. If desired,

-, oil holes 40 may be formed in the flanges of the stationary hinge member to communicate with the grooves 36.,

As the door is swung, the movable hinge member 27 is supported to a large extent on the balls 37 which roll or slide in the grooves or tracks 36. Movement of the hinge member 2'7 in a radial direction is resistedby the balls, thus relieving the pintle 31 of most of the radial load. When the door is closed, an inward pressure on the movable hinge member is resisted by the shoulder formed at the recess 34, engaged by the nose 28 of this hinge member, thereby avoiding any tendency for the balls to shift into the entry grooves 39, and reducing radial thrust on the pintle. A slight opening movement of the door is sufiicient to move the balls out of register with the entry grooves. The construction of the hinge is such that the segmental ball track has a relatively large radius without requiring an excessively wide and deep hinge, and a single ball in the track will provide an effective anti-friction bearing.

What I claim as new and desire to secure by Letters Patent is:

1. In a hinge, the combination of a pair of relatively movable hinge members, one of which has spaced cheeks receiving therebetween the other hinge member, a pintle connecting said hinge members, at least one of said cheeks having an arcuate groove concentric with said pintle, a ball movably mounted in said groove and movably seated in the other hinge member, there being a ball entry groovein said-cheek extending from said arcuate groove, and there being a pair of co-operative abutments on said hinge members remote from said pintle and engageable when said ball is at said entry groove to prevent shifting of the ball into said entry groove and to reduce radial thrust on said pintle. J

2. In a-hinge, the combination of a pair of relatively movable hinge members, one of which has spaced cheeks receiving therebetween the other hinge member, a pintle connecting said hinge members, at least one of said cheeks hav- 1 ing an arcuate groove concentric with said pintle,

and a ball movably seated insaid groove and movably seated in the other hinge member, there being a pair of co-operative abutments on said hinge members spaced from said pintle and engageable when the hinge is closed to reduce lateral thrusts on said ball and on said pintle.

3. In a hinge, the combination of a pair of relatively movable hinge members one of which has spaced cheeks and the other of which has a hooked portion received between said spaced cheeks, a pintle connecting said spaced cheeks and the end of said hooked portion, at least one of said cheeks having a segmental arcuate groove concentric with said pintle, said pintle being arranged near one side edge of said check and said groove having a portion near the other side edge of said cheek, and a rollable member movabLv seated in said groove and in said hooked portion and resisting both axial and radial thrust on the hinge.

4. In ahinge, the combination of a hinge member having spaced cheeks and a wall integrally connecting said cheeks and forming therewith a recess, said recess having a front opening and said wall being spaced rearwardly fromv said opening, a hinge knuckle formed on said wail within said recess, a second hinge member having a hooked portion extending into said recess and having terminal hinge'knuckles embracing said first-named knuckle, and a pintle connecting said cheeks and said several knuckles and disposed adjacent said cheek-connecting wall.

5. In a hinge, the combination of a hinge member having spaced cheeks and a wall integrally connecting said cheeks and forming therewith a recess, "said recess having a front opening and said wall being spaced rearwardly from said opening; a second hinge member having a hooked portion .extending into said recess, a pintle con necting said spaced cheeks and the end-of said hooked portion and arranged ad iacent said wall, at least one of said cheeks having a segmental arcuate groove concentric with said pintle, and a rollable member movably seated in said groove and in said hooked portion and resisting both axial and radial thrust on the hinge.
