Definitions

  • FIG. 1 is an elevational view of a sashless window
  • FIGS. 2 and 3 are front and side elevational views respectively of the herein described latch assembly
  • FIG. 4 is a sectional view taken along line 4-4 of FIG. 2 and illustrating particularly the locking plate which is a component of the presently described latch assembly;
  • FIG. 5 is an exploded view further illustrating the latch assembly
  • FIG. 6 is a detail view, enlarged and partly in section, illustrating the manner of mounting the presently described latch assembly on the window pane.
  • the instant latch assembly is applicable to a sashless window comprising a pair of panes 10, 12, having their adjacent edges overlapped.
  • the panes are mounted in a frame comprising a sill 14, a head piece 16 and a pair of side jambs 18, 20.
  • the outside side edges of the panes are received in grooves 22, 24 of side jambs 18, 20 respectively.
  • Their upper and lower edges are received in guideways 26, 28 in head piece and sill respectively so that one of the panes, e.g. pane 12, can slide back and forth with respect to the other to open and close the window opening.
  • Guideway 28 in the sill is enlarged to form a central recess or cavity 30 (FIG. 3).
  • a locking plate 32 adjustably secured to the sill by means of screws 34.
  • the inside edge 36 of this plate i.e. the edge adjacent the window, is cut away centrally to form a deep recess 38.
  • Shallower recesses 40 are also formed in edge 36, separated from central recess 38 by projections 42. Such a symmetrical locking plate construction is preferred so that it may be applied with equal facility to windows which open either to the left or to the right.
  • the stud preferably comprises a bolt 46 having a flat tapered head 48, a central threaded segment 50 and an internally threaded terminal aperture 52.
  • the stud may be placed in opening 44 through the pane after which it receives, in the order named, a washer 54 of rubber or other deformable material, a knurled lock nut 56, a rubber cushion washer 58, and a steel retainer washer 60.
  • Stud 46 also mounts a leaf shaped latching member 62, the base of which is centrally apertured at 64 to receive retainer washer 60 and provided with a central recess 66 sized to receive the shank of stud 46.
  • Recess 66 opens out to the exterior to afford access for a screw 68, the threaded portion of which incorporates When the various elements of the latch are assembled screw 68 is received in threaded engagement with threaded recess 52 in stud 46.
  • Latch 62 carries at its lower end a hook-shaped extension 72. It extends downwardly into recess 30 in the sill beneath plate 32 and makes possible operation of the:
  • the latch extension may be rotated out of recess 38 so that the pane 12 may be moved to fully opened position.
  • the head 48 of stud 46 separates the panes and prevents scratching of the glass.
  • latch 62 may be maintained in any desired position of angular adjustment since screw 68, assisted by plastic plug 70, maintains the desired degree of frictional engagement between the screw and the latch. This desirable condition can be maintained in spite of discrepancies in glass thickness and despite the tendency of the screw to work loose with use. Hence when operating sashless storm windows, the latch may be maintained horizontal when it becomes inaccessibly located behind the inside pane and will not drag upon or mutilate the window sill.
  • deformable washer 54 squeezed into the opening in the glass around stud 46 (see FIG. 6), provides a cushion, preventing the glass from cracking because of temperature change or leverage exerted by the stud.
  • rubber washer 58 continuously and resiliently urges the latch into recess 40, when in locked position, and into recess 38 when in partially open position, there- "by insuring a positive lock.
  • a latch assembly including a locking plate having a locking edge and adapted to be mounted on the frame with its locking edge spaced from the frame and extending substantially parallel to the movable pane, a first projection extending from the locking edge intermediate the ends thereof and having a latch abutting edge facing the closing direction of the movable pane, a second projection extending from the locking edge and having a latch abutting edge facing the closing direction of the movable pane, the second projection being spaced from the first projection longitudinally in the opening direction of the movable pane, a latch member having a locking projection and adapted to be mounted on the movable pane for movement toward and away from the pane, means biasing the latch member to a latching position in which the locking projection underlies the locking edge of the locking plate and the, latch member may selectively engage one of the abutting edges of the projections, the
  • first and second projections on the locking plate also have latch abutting edges extending intermediate the ends of the locking edge and facing the direction opposite the first named latch abutting edges, whereby to accommodate the locking plate selectively for window panes which open from opposite directions.
  • the latch member includes a headed bolt adapted to extend through an opening in the movable pane with the bolt head projecting from the side of the pane facing the other pane, and wherein the portion of the locking edge between the first and second projections is displaced from the locking edge portion adjacent the first projection by substantially the projecting thickness of the bolt head.
  • the latch member mounting means includes a headed bolt adapted to extend through an opening in the movable pane with the bolt head on the side of the pane facing the other pane, locking nut means on the bolt for securing the pane between it and the bolt head, the latch member is mounted on the bolt, the biasing means comprises a resilient member interposed between the locking nut means and latch member, and adjustable means is provided for interengaging the bolt and latch member for moving the latch member relative to the locking nut, whereby to adjust the compression of the resilient member.
