  • the pivot members 6 and 7 are received intermediate the leg portions 18, 18 and the leg portions may be laterally bulged as at 19 to permit the outer pivot member 6 to be formed with a greater width than that of the inter pivot member 7.
  • pivot pins 21 and 22 are provided and extend between the leg portions 18, 18 of the carrier arm.
  • the pivot pins 21 and 22 are disposed along a line B tilted upwardly at an angle beta from an inner surface 23 of the carrier wall 2, thereby to mount the pivot arms 6 and 7 in the proper arrangement to provide the desired quardilateral swing motion.
  • each end portion of the pivot members 6 and 7 is formed in a reverse bend as at 24 forming a substantially cylindrical bearing surface pivotally engaging the pivot pins 12 and 13 of the holder 3 and the pivot pins 21 and 22 of the carrier arm 4.
  • a mounting plate 16 is securely fastened to the carrier wall 2 and arranged to detachably mount the carrier arm 4, thereby permitting the hinge to be fitted during manufacture and subsequently disassembled for shipping without disturbing the fitted relationship between the door 1 and the carrier wall 2 when the hinge is later assembled at a point of destination.
  • the mounting plate 16 has a generally channel-shaped configuration in transverse cross section and includes a pair of confronting wall surfaces 25, 25 interconnected by a bottom wall 26 and spaced apart a distance to fittingly receive the carrier arm 4.
  • Means detachably mounting the carrier arm 4 to the mounting plate 16 include an elongated slot 27 formed centrally within the base portion 17 of the carrier arm and characterized by outwardly flared, longitudinal sidewalls as at 28 forming a pain of tapered wall portions as as 29, and an attachment screw 31 received within the elongated slot 27 and engaged into a threaded aperture 33 formed in the mounting plate 16.
  • the attachment screw has a frusto-conical head portion 32 and the tapered wall surfaces 29 are formed complementary to the frusta-conical head portion.
  • the frustoconical head portion 32 laterally urges the leg portions 18 of the carrier arm 4 in opposite directions and into firm clamping engagement with the confronting wall surfaces 26 of the mounting plate 16, thereby enabling secure attachment of the carrier arm to the mounting plate with only a single attachment bolt.
  • the mounting plate 16 is fastened to the carrier wall 2 by a pair of spaced apart fasteners, such as wood screws 33 and 34. To obtain the maximum stability in a limited space, the fasteners are spaced as far apart as the available space will permit. Also, the total length of the mounting plate 16, and the carrier arm 4 should be maintained at a minimum to provide a compact hinge consuming a minimum of space within a cabinet.
  • the forwardmost fastener 33 may be disposed immediately subjacent the pivot pin 22 supporting one end portion of the inner pivot lever 7.
  • the fasteners 33 and 34 desirably include flat-head wood screws received within countersunk apertures as at 36 formed in the bottom wall of the mounting plate 16. The fasteners 33 and 34 are threaded into the carrier wall 2 in a manner to securely hold the mounting plate in position.
  • the placement of the fastening screws permits the mounting plate 16 to be positioned flush with a marginal end edge of the carrier wall 2.
  • the mounting plate 16 may be of symmetrical design, thereby enabling the carrier arm 4 to be mounted from either direction.
  • a plastic shroud member 36 encircles the mounting plate 16.
  • the shroud member 36 has a generally channel shape in transverse cross section and includes outwardly projecting sidewalls 37 extending along opposite edges of the mounting plate and characterized by offset portions as at 38 engaging around outer corners of the mounting plate, thereby securing the shroud member in a desired position.
