Definitions

  • This invention relates to pivot-bearing assemblies for pivot-windows and similar structures, adapted to be swung through an angle of about 180.
  • pivot-bearing assemblies for the purpose described having two parallel pivots adapted to support alternatingly the window-sash or other pivoted structure when the latter is swung through an angle of about 180, without the unbalanced weight of the structure becoming very great in any angular position. It is, therefore, a further object of the invention to provide pivot-bearing assemblies having their pivots closely spaced.
  • the pivot-bearing assembly comprises two parallel pivots, the first of which is stationary by being rigidly secured to the window-frame, or the like, whereas the second pivot is detachably secured to the window-sash, or the like, said pivots being formed as circular, comparatively thick discs rotatably disposed relative to a common housing, said discs being each sha ed with a preferably a-rcuate recess, the radial depth of which is less than the ditsance between the disc centres, said discs overlapping so that the circumference of the first disc upon its rotation through an angle of, say, 90 will engage the recess of the second disc to prevent rotation thereof until the recesses of both discs have become juxtaposed, in which position abutting means will arrest rotation of said first disc, whereupon the circumference of said second disc will engage the recess of the first disc and prevent the rotation of the latter at the same time as the second disc will be freely rotatable.
  • FIG. 1 is a diagrammatical side elevation view of a pivot-bearing assembly for a pivot window with the parts assuming the position in which the window is shut,
  • FIG. 2 is a similar view as FIG. 1 when the windowsash has been opened about 30,
  • FIG. 3 is a similar view as FIG. 1 when the windowsash has been opened about
  • FIG. 4 is a similar view as FIG. 1 when the windowsash has been rotated through about
  • FIG. 5 is a sectional view along V-V in FIG. 1,
  • FIG. 6 is a sectional view along VI-VI in FIG. 4, and
  • FIG. 7 is a sectional view along VIIVlI in FIG. 1.
  • window-frame and the windowsash have not been specifically illustrated, but their possible shapes and dispositions will be obvious to anyone skilled in the art.
  • a pivot-bearing assembly comprises a housing 3, two partially overlapping discs 6, 7 rotatably disposed within circular bores 4, 5, respectively, in the housing 3, a bracket 1 rigidly secured to the first disc 6, and another bracket 2 which is attached separably to the second disc 7 in a manner preventing any torsional displacement between said elements.
  • Bracket 1 will preferably be attached to a windowframe or the like by means of screws, whereas bracket 2 will be screwed onto a window-sash or the like.
  • the housing 3 preferably made of a light alloy, is formed with two bores 4, 5 which are sunk in the housing from opposite faces thereof and which each have a bottom.
  • the bores have circular cross-section and a diameter and depth which corresponds substantially to the diameter and the thickness of the discs 6, 7, and they intersect somewhat.
  • the bottom of each bore 4, 5 is pierced by a central bore for a central stud member passing through the corresponding disc, said stud members each shaped with a head abutting the outer wall of the housing 3.
  • the first stud member 9 (FIG. 5) extends beyond the opposite face of disc 6 and is threaded. It may be secured with a nut and a locking washer to the bracket 1, to clamp the disc 6 rigidly against the latter.
  • the second stud member 12 (FIG. 1) is adapted to journal rotatably the disc 7 in the bore 5 by means of a stationary, internally threaded bush (not illustrated).
  • Both discs 6, 7 are formed with a radially extending open split, and coinciding with each slit and between the ends thereof an axially extending bore 26 with opposed frusto-conical portions is provided.
  • This bore receives expanding means 13, 14, respectively, preferably comprising a conical screw and a conical nut (FIG. 6) which may be tightened or loosened to expand or narrow the slit, thus varying the friction between the circumference of each disc and the corresponding wall of each bore 4, 5, making it possible to set the discs 6, 7 in any angular position independently of the position of the gravity axis of the window-sash.
  • Each disc 6, 7 is formed at its circumference with a substantially arc-shaped recess 15, 16. These recesses preferably extend only over so great a portion of the Width of the discs as corresponds to the length of the common portions of the bores 4, 5. As thus the circircumference of one disc may engage the recess of the other, the discs may overlap with an amount corresponding to the radial depth of the recess.
  • the first-mentioned disc When the recess of one disc faces the intersection of the bores 4, 5, and the circumference of the other disc engages said recess, the first-mentioned disc is prevented from turning, whereas the other disc may be freely rotated.
  • the disc 6 which is rigidly clamped to bracket 1 is formed in the face thereof adjacent the bottom of bore 4 with an arcuate slot 18, in which a stud member 17 projecting from the bottom of the bore engages to form a pin-and-slot connection.
  • a stud member 17 projecting from the bottom of the bore engages to form a pin-and-slot connection.
  • the recess 15 faces the intersection of bores 4, 5, that is the recesses 15, 16 of both disc 6, 7 are juxtaposed.
  • the second disc 7 may begin to be rotated so that its outer circumference engages the recess 15 of the first disc 6 and locks the latter against rotation, whereas the other disc 7 has now become freely rotatable.
  • the central stud 9 passing through disc 6 may be formed with opposed flats or may have a square cross-section or the like, passing through an arcuate slot 8 in the bracket 1 to form a torsionally rigid connection.
  • the disc may be formed with a square projection at that face, engaging the said arcuate slot.
  • the disc 7 which is rigidly attached to bracket 2 is formed at the surface adjacent said bracket with a diametrically extending slot 10, preferably with a T-shaped cross-section.
  • This T-slot 10 is adapted to receive a bar 11 with a corresponding cross-section, rigidly secured to bracket 2.
  • a slot with a corresponding cross-section (not illustrated) is formed in the wall of the housing 3.
  • the slots are preferably disposed and arranged in such a way that the window-sash, when swung 180, may be lifted out of the bearings, the slots being aligned in that position. No special loosening measures have thus to be taken.
  • the window-sash is mounted in its position in an analogous manner.
  • bores 19 may be provided through the bottom of each bore 4, 5 at the same radial distance from the centre as the bores 20 in the discs.
  • pivot-bearing assembly comprising two parallel pivots, one of which has a stationary axis and is rigidly attached to bracket means adapted to be secured to the stationary structure, such as a window-frame, whereas the second pivot is rigidly connected to bracket means adapted to be rigidly secured to the pivoted structure, such as a window-sash, said pivots comprising a housing and comparatively thick circular disc members rotatable therein, said disc members spaced at a center distance less than the sum of their radii, there being a substantially arcuate recess at the circumference of each disc member to enable the first disc member to engage the recess of the second disc member during the rotation of said first disc member through a desired angle, and thus to prevent the second disc member from rotating until the recessed portions of both disc members face each other, means being provided for arresting the rotation of the first disc member upon attaining said position, and thus to permit the outer circumference
  • a window-sash may be swung through the provision of at least one pivot assembly comprising two pivots with parallel axes, said pivots each formed as a comparatively thick circular pivot disc, means for rigidly attaching the first one of said pivot discs to a stationary window structure, such as a window-frame, means for rigidly securing the second pivot disc to a pivoted structure, such as a window-sash, there being an arcuate recess in the circumference of each pivot disc, a housing having two partly intersecting, oppositely facing parallel sack bores therein, each one adapted to receive rotatably one of said pivot discs with the recess of one disc normally engaging an edge portion of the other disc, means for adjusting the frictional resistance between the circumference of said pivot discs and the surrounding walls of said sack bores, means for limiting the pivoting movement of said housing relative to said first pivot disc, said means comprising a pin-andslot connection between the said first pivot disc and the bottom of the
  • pivot-bearing assembly comprising two pivots with parallel axes, said pivots each formed of a comparatively thick, circular-shaped disc, a first bracket member for rigidly securing the first one of said discs to a stationary structure, such as a window-frame, a second bracket member adapted for rigidly securing the second disc to a pivoted structure, such as a windowsash, there being an arcuate recess at the circumference of each disc over at least part of its width, a housing having therein two partly intersecting, oppositely facing axially staggered sack bores with substantially the same diameter as the discs, each bore adapted to receive rotatably one of said discs with the recess of at least one disc engaging an edge portion of the other disc, in each disc an open radially extending slit, there being an axially extending bore with opposed frusto-conical portions coin
