Definitions
- the invention relates in general to self-latching hinges and more particularly to an economical self-latching and closing cabinet hinge of pleasing appearance.
- the present invention avoids the above problems through the use of a leaf spring in the space between the two hinge leaves.
- the leaf spring depends from the hinge pin in a coplanar abutting relationship with the leg forming the knuckle of one of the hinge leaves.
- a tab on the end of the spring projects toward the other leaf for engagement with a ⁇ latch rotated with the opposite leaf in response to closing of the door with the spring also serving to bias or rotate the door closed.
- the latch is formed integrally with the other leaf While the spring also being of metal permits facile camouflage of the parts. Due to the simplicity of the arrangement, extreme economy is obtained in the minimum of space.
- one object of the present invention is the provision of a more economical self-latching and closing cabinet hinge.
- Another object of the present invention is the provision of a self-latching hinge of improved appearance and/or size.
- a hinge assembly is indicated therein by the reference character 10.
- the hinge assembly comprises a frame leaf 12 and a door leaf 14 fastened, respectively, to a cabinet frame 16 and a cabinet door 18 by means such as screws 20.
- the frame leaf 12 is generally L-shaped with one leg 22 fixed to the frame 16 and the other leg 24 projecting outwardly of the frame and having a knuckle or loop 26 formed at the end of the leg 214 for receiving a hinge pin 28.
- the pin 28 has a head 30 at each end.
- the other hinge leaf 14 is also generally L-shaped with one leg 32 fastened to the inside surface of a conventionally rabitted door and the other leg bifurcated to form two spaced arms 34 with a respective knuckle 36 on the end of each arm 34 looped over the pin 28 adjacent the opposite pin ends.
- the two arms 34 are joined at a position just below the hinge pin 28 and adjacent knuckle 26 by an integrally formed latch 38.
- Latch 38 projects downwardly and towar-ds leg 24 of leaf 12 as seen in FIG. 2, when the door is closed, and terminates at a position intermediate legs 24 and 34 and spaced from frame 16 with an upwardly or reverse tab 40 on the end thereof directed toward pin 28.
- the latch 38 is engaged by a cantilever leg 42 of a leaf spring 44 to latch the door in closed position.
- the leg 42 of leaf spring 44 is formed on the end of a leg 46 parallel and adjacent leg 24 and projects from adjacent the door frame 16 toward latch 38 for engaging latch 38 so as to bias latch 38 in a clockwise direction as seen in FIG. 2.
- the leg 42 terminates at the end opposite leg 46 in a downwardly extending arcuate tab 48 for facilitating engagement between latch 38 and spring 44 on closing movement of the door 18.
- the leaf spring leg 46 opposite leg 42 terminates outwardly of the frame in a knuckle or loop 50.
- the loop 50 wraps around a reduced diameter portion of the pin 28 to accommodate the loop 26 on leg 24 overlapping loop 50 so that loop 26 occupies the same external diameter as loops 36.
- the loop 26 terminates in a tongue 52, which engages the leg 46 of spring 44 to prevent rotation of the spring leg ⁇ 46 from its position adjacent leg 24.
- the latch 38 On opening of the door 18, the latch 38 swings counterclockwise about the axis of pin 28, as seen Iby the difference in the latch position between FIGS. 2 and 3.
- the latch 38 disengages from the spring leg 42 after flexing the leg downwardly as seen in FIG. 2 about the juncture of legs 42 and 46.
- the spring pressure is relieved against latch 38 to rotate the latch 38, leaf I14 and door 18 toward the closed position.
- the door is then held latched closd by the latch 38 engaged behind the spring leg 42 and in the space defined vby the acute angle formed between spring legs 42 and 46.
- Camouflage of the latch and spring are provided by the overlapped door 18 and since the latch and spring are of metal, their finish and appearance correspond to the leaves 12 and 1'4.
- a self-latching hinge for use in hnging a door to a frame comprising a pair of hinge leaves fixed to said door and said frame respectively, a pin, a leg on each leaf terminating in a knuckle looped over a respective axial portion of said pin, a leaf spring having a loop on one end wrapped over said pin with said loop extending axially of said pin and overlapped by a knuckle on one of said leaves, a leg projecting from the other endof said leaf spring, and a latch integrally formed on the other of said leaves for engagement by said projecting leg to latch sa-id door closed in response to said door being moved to a closed position and adapted to flex said projecting leg for disengaging said latch from said projecting leg in response to an opening movement of said door.
- a self-latching hinge for use in hing-ing a door to a frame comprising a pair of hinge leaves fixed to said door and said frame respectively, a pin, a leg on each leaf terminating in a knuckle looped over a respective axial portion of said pin, a leaf spring having a loop on one end wrapped over said pin, a leg projecting from the other end of said leaf spring, a latch integrally formed on one of said leaves for engagement by said projecting leg to latch said door closed in response to said door being moved to a closed position and adapted to flex said projecting leg for disengaging said latch from said projecting leg in response to an opening movement of said door, and a reduced diameter portion formed in said pin with said leaf spring loop wrapped over said reduced diameter portion and the knuckle of said hinge leaf fixed to said frame overlapping said leaf spring loop whereby the outer surface of each knuckle occupies the same diameter.
- a tongue formed on the end of said overlapped knuckle for holding said leaf spring in abutting relationship with the respective hinge leaf leg.
- a self-latching hinge for use in hinging a door to a frame comprising a pair of L-shaped hinge leaves one of which has one leg fixed to said door and the other of which has one leg xed to said frame, a pin, a knuckle on each other leg of each hinge leaf looped over a respective axial portion of said pin, rsaid pin having a reduced diameter portion adjacent the axially central portion of said pin, a leaf spring, a loop on one end of said leaf spring wrapped over said reduced portion and overlapped by the knuckle on one leaf fixed to said door, a tongue on the end of said knuckle overlapping said loop for holding said leaf spring in abutting relationship with said other leg of said leaf spring'fixed to said frame, a leg on the other end of said leaf spring projecting from said leaf spring at an acute angle toward the other leg of the hinge leaf xed to said door and terminating in a tab directed toward the surface of said frame, and a latch integrally formed on said hinge leaf fixed
- said latch comprises a projection from the other leg of said hinge leaf fixed to said door and said latch terminates intermediate the other leg of each hinge leaf in response to said door being in closed position.
