  • FIG. 15 is a vertical section view taken along the line 1515 of FIG. 14.
  • pivot assembly devices or mechanisms which are representative of one embodiment of the present invention are designated generally by the numeral 14.
  • Each of the pivot assemblies includes a pintle arrangement and pintle receiving mechanism which in the present instance is in the form of camming means, as will be discussed more completely hereinafter.
  • the camming means in conjunction with the pintle arrangement, is effective to produce lateral displacement of the door member 18 relative to the jam or frame member 40 during opening movement; and further attains this end while permitting the door to open in either direction.
  • FIGS. 2-4 an aperture plate or bracket 16 is secured to the edge surface of the door, by means of screws 20, or the like.
  • a vertical pintle device 24 is fixed at one extremity within each plate or bracket members 16 and extend into vertical recesses 25 provided in the door member 18.
  • the other extremity of each of the pintle devices 24 projects or extends from the surface of the plate members 16.
  • the projecting extremity of each pintle device 24 is noncircular and is, as will be explained, accommodated by the pintle receiving camming means.
  • each said camming means ins; es plate or base member 28 having a slot 26 therein, and overlies the base member 30 to serve as a cover therefor.
  • the. camming means includes a polygonally shaped carn rr: ember 32, viz., multi-lobular, which is provided with a non-rircular aperture 29 for receiving the projecting extremity of the pintle device 24, which is of a complementary shape.
  • the cam member 32 also includes a depending, generally circular protuberance 34, the purpose and function of which will be explained hereinafter.
  • Each of the base members or plates 30, which are mounted within horizontal upper and lower door frame sections 31, are provided with recesses 36, FIG. 2, for accommodating the polygonally shaped cam member 32.
  • the inner periphery of the recess 36 is complementally shaped with respect to the outer periphery of the polygonally shaped cam member 32 and defines a cam engaging surface.
  • a shallow recess of slot 38 in the base member 30 serves to accommodate and guide the circular section 34 depending from the underside of the member 32, thus mounting the cam member 32 for rotatable, longitudinal movement relative to said base member 30.
  • each pintle device 24 includes a pintle member 24a, a coil spring 24b, a split ring washer 24c and a clamping nut 24d.
  • the pintle members 24a are polygonal in cross sectional shape and are longitudinally adjustable within complementary polygonally shaped apertures within their complementary plates 16.
  • the clamping nuts 24d are accommodated by complementary threads of the pintle member 24a.
  • the split ring washers 24c are accommodated by a peripheral recess at the inner extremity of a complementary pintle member and provide a shoulder against which the upper extremity of the coil spring 24b may bear. By rotating the nut 24d, the pintle member 24a may be vertically adjusted within the recess 25.
  • the coil spring 24b being interposed between the split ring washer 24c and the inner surface of the plate 16 constantly urges the clamping side of the nut 24d against the external surface of the plate 16 as will be clearly understood from FIG. 2.
  • the pintle members 24a When the door member 18 is initially inserted within the door opening, the pintle members 24a must be fully retracted within the respective recesses 25. After such insertion, the nut members 24d may be rotated so as to cause axial projection of the pintle members into telescopic association with their respective polygonally shaped plate members 32. It will be apparent that the coil springs 24b also function to secure the clamping nuts 24d against unauthorized rotation with respect to an associated pintle member. Further, the nuts 24d and the adjustability afforded thereby provide an additional advantage in that the height of the door above the lower frame portion 31 can be altered. For example, the nuts 24d for the lower pivot assembly would be turned to increase the amount of projection of the pin- 24a for the upper assembly would be retracted.
  • FIG. 9 discloses the relative positions of the apices A, B and C with respect to the peripheral surface defining the recess 36 when the door member 18 is in its fully open position.
  • FIGS. 10 and 11 illustrate the relative positions of the moving parts when the door member is shifted in a clockwise direction.
  • FIG. 10 discloses the door member shifted through 20.
  • the solid line position of the polygonal or triangular member 32 illustrates the relative positions of the parts when the door member is shifted through in a counter direction.
  • the dot and dash line position of the member 32 in FIG. 11 illustrates the relative positions of the parts when the door member has been shifted in a clockwise direction to its full open position.
  • the pivoted edge is closely spaced with respect to said frame in the closed condition.
  • FIGS 12-15 an additional feature of the present invention is disclosed, namely an adjustable mounting bracket for the pintle mechanism to be employed with the upper door portion.
  • previously described components will be designated by the same reference characters, with the addition of a prime ('l-
  • pintle mechanism 24 of FIG. 12 can be employed with the cam type mechanism discussed previously, or with other conventional pivot assemblies.
