Definitions

  • This invention relates generally to apparatus for use with windows and specifically for use with windows such as a casement window having a sash or light which is adapted to be swung about an upright axis between closed and open positions.
  • Modern casement windows usually are associated with a reversible rotary actuator which may be used to open and close the window sash.
  • the actuator may be in the form of a hand crank adapted to be turned in one direction to open the sash and in the opposite direction to close the sash.
  • the actuator may be a reversible electric motor which is associated with the sash in the manner disclosed in Lense United States Patent 4,553,656.
  • a casement window usually is equipped with one or more latches for locking the sash in its closed position. While the latch may be power-operated as disclosed in Lense United States Patent 4,703,960, the latch more conventionally is operated manually. If the latch is locked, it must be unlocked before the sash can be opened and then must be re-locked to secure the sash after the latter has been closed. In prior windows with manually operable latches, two separate operations are necessary in order to unlock and open the sash and then two more separate operations are required to close and lock the sash. In some cases, the sash may be fully closed but inadvertently left in an unlocked condition.
  • Vetter et al United States Patent 4,497,135 discloses mechanism for automatically unlocking and opening a sash and for automatically closing and locking the sash. That mechanism, however, is relatively complex and requires a motor, planetary gearing driven by the motor and a trigger for sensing the position of the sash.
  • the general aim of the present invention is to provide new and improved window apparatus in which the sash actuator is uniquely linked to the sash and to the sash latch by relatively simple mechanism capable of effecting automatic unlocking of the latch when the sash actuator is operated to open the sash and automatic locking of the sash when the actuator is operated to close the sash.
  • the sash actuator to effect automatic unlocking of the sash just prior to opening of the sash and to effect automatic locking of the sash at about the same time the sash reaches its fully closed position without need of relying on a sensor or the like for detecting the position of the sash.
  • the invention also resides in the novel construction of the latch to facilitate the opening of a stuck sash and to help draw the sash to a fully closed position.
  • the drawings show apparatus for causing a casement window sash 20 to swing between closed and open positions in a window frame 21 and for releasably locking the sash in its closed position.
  • the sash itself is of conventional rectangular construction and includes a glass pane 22 which is supported by horizontal top and bottom members 23 and 24 and by left and right upright side members 25 and 26.
  • the frame 21 also is rectangular and is defined by a top header 27, a bottom sill 28 and by left and right side jambs 29 and 30 (FIG. 3).
  • Generally channel-­shaped moulding strips 31 (FIG. 6) and 32 (FIG. 3) extend alongside the sill 28 and the right side jamb 30, respectively, a moulding strip 33 (FIG. 3) extends alongside the left side jamb 29 and an additional moulding strip (not visible) is located alongside the header 27.
  • a screen 34 (FIG. 2) is removably positioned in the opening defined by the frame 21.
  • a horizontal track 35 (FIG. 7) is attached to the sill 28 adjacent the left side jamb 29 and is formed with an elongated and laterally extending slot 36.
  • the slot receives a pivot pin 37 which extends downwardly from the bottom member 24 of the sash.
  • Similar structure (not fully visible) is located at the upper left portion of the sash.
  • the pin 37 moves from left-to-­right in the slot 36 and, at the same time, the sash swings counterclockwise (FIG. 7) about the axis of the pin.
  • the sash swings clockwise about the axis of the pin 37 as the sash is closed and as the pin moves from right-to-left in the slot 36. Movement of the sash is controlled in part by a swivel arm 38 having an outer end pivotally connected to the bottom member 24 of the sash and having an inner end pivotally connected to the sill 28. A similar swivel arm 39 (FIG. 1) is located at the top of the sash.
  • Opening and closing of the sash 20 is effected by a reversible rotary actuator 40 which, in this particular instance, includes a conventional hand crank 41.
  • the crank is connected rigidly to the inner end portion of a spindle 42 (FIG. 2) which is rotatably journaled in an actuator cover 43 fastened to the sill 28 by screws 44 (FIG. 4).
  • a bevel gear 45 (FIG. 2) on the outer end of the spindle meshes with a bevel gear 46 on a shaft 47 which is rotatably supported within the cover and which carries a worm 48.
  • the sash 20 is opened and closed when the crank 41 is turned clockwise (FIG. 1) and counterclockwise, respectively.
  • each latch includes a base plate 51 (FIG. 9) fastened to the right side jamb 30 and located between the jamb and the channel-shaped moulding 32.
  • a latching bolt 53 formed with a U-shaped notch or throat 54.
  • the latch bolts of the upper and lower latches 49 and 50 are adaptd to coact with upper and lower strikes 55 and 56 (FIGS.
  • Each strike includes a generally triangular mounting plate 57 (FIGS. 9 and 11) attached to the frame member 26 and supporting a horizontal pin 58 which projects toward the right side jamb 30.
  • the strike pins 58 are captivated within the throats 54 of the latch bolts so as to prevent opening of the sash 20.
  • the throat 54 releases the strike pin and frees the sash to open.
  • a torsion spring 59 encircles the mounting pin 52 of each latch bolt and urges the latch bolt toward its unlocked position.
  • Operation of the rotary actuator 40 in one direction automatically effects movement of the latching bolts 53 to their unlocked positions and then effects opening of the sash 20.
  • the rotary actuator When the rotary actuator is operated in the opposite direction, the sash is closed and, at about the same time the sash reaches its fully closed position, the actuator effects automatic movement of the latch bolts to their locked positions. In this way, only one operation is required to unlock and open the sash and only one operation is required to close and lock the sash.
  • the rotary actuator 40 includes an actuating or driver arm 60 which is supported to turn back and forth about a vertical pivot defined by a screw 61 in the cover 43.
  • the inner end portion of the driver arm is formed with gear teeth and defines a gear segment 62 which meshes with the worm 48 of the actuator 40.
  • the hand crank 41 of the actuator When the hand crank 41 of the actuator is turned back and forth, it acts through the bevel gears 45 and 46, the worm 48 and the gear segment 62 to turn the driver arm 60 back and forth about the pivot 61.
  • a pair of identical and vertically spaced links 63 (FIGS. 3 and 5) are pivotally connected to the free end portion of the driver arm at 64.
  • the opposite end portions of the links 63 pivotally receive a vertical drive pin 65 connected rigidly to and projecting upwardly from a block-like slide 66 which forms part of an actuating linkage to the latches 49 and 50.
  • the slide is located within a metal guide or track 67 of inverted U-shaped cross-section extending along the sill 28 and fastened to the sill by screws 68.
  • a plastic guide channel 69 (FIG. 2) is located in the track 67 and supports the slide 66 for back and forth movement in the track.
  • the drive pin 65 travels in a straight slot 70 (FIG. 3) formed through the top of the track 67 and extending lengthwise of the sill 28.
  • a longitudinally stiff but laterally flexible elongated member Connected to the lower side of the slide 66 by a pair of rivets 71 (FIG. 5) is one end portion of a longitudinally stiff but laterally flexible elongated member which herein is a length of tape 72 made of metal or plastic.
  • the tape 72 extends between the guide channel 69 along the sill 28 toward the right side jamb 30 and then curves upwardly and extends along the jamb, the guide channel also curving upwardly and extending along the jamb.
  • the upper end portion of the drive tape 72 is connected by fasteners 73 to a block 74 which is supported for up and down sliding in the guide channel 69.
  • a mounting bracket 75 (FIG.
  • the bar 77 When the sash 20 is fully closed, the bar 77 is positioned as shown in FIG. 9 and, when so positioned, vertically spaced pins 79 on the bar bear against vertically extending edges 80 of the latch bolts 53 and positively hold the latch bolts against turning counterclockwise from their locked positions.
  • the pins 79 move upwardly off of the vertical edges 80 and effect unlocking of the latch bolts in a manner which will subsequently be described in detail.
  • Downward return of the bar to the position shown in FIG. 9 causes the pins to turn the latch bolts clockwise to their locked positions in a manner which also will be described in more detail below.
  • the same actuator arm 60 for unlocking and locking the latches 49 and 50 also acts through a linkage to effect opening and closing of the sash 20.
  • the linkage includes an arm 81 (FIG. 7) pivotally mounted to turn about a vertical screw 82 in the cover 43 and formed with a slot 81 which receives the driver pin 65.
  • Part of the arm 83 overlies the track 67 and its free end is pivotally connected at 84 to one end of a link 85.
  • the other end of the link is pivotally connected at 86 to a bracket 87 secured to the bottom member 24 of the sash 20 adjacent the left side member 25 thereof.
  • the slot 83 in the sash arm 81 is shaped such that, when the sash 20 is fully closed, initial clockwise turning of the driver arm 60 causes the pin 65 to shift the slide 66 to the right to effect unlocking of the latches 49 and 50 but does not produce movement of the sash arm 81 to open the sash 20.
  • continued clockwise turning of the driver arm 60 causes the pin 65 in the slot 83 to effect clockwise turning of the sash arm 81 and opening of the sash 20.
  • the slot 83 in the sash arm 81 is formed with an elongated straight portion 88 which overlies and extends parallel to the slot 70 in the track 67 when the sash 20 is fully closed and locked as shown in FIG. 3.
  • the slot 83 is formed with a curved portion 89 which extends generally inwardly.
  • the curved portion 89 of the slot 83 is shaped and located so as to avoid binding interference with the pin 65 as the arm 81 turns and as the pin moves in the slot 70.
  • the arms 60 and 81 are positioned as shown in FIG. 3 and, in this position, the driver pin 65 is located in the straight portion 88 of the slot 83.
  • the links 63 pull the driver pin 65 to the right and, because the driver pin is constrained by the slot 70 in the track 67, the pin travels in a straight line and produces no turning force against the edges of the straight portion 88 of the slot 83 in the sash arm 81.
  • the pin 65 does, however, cause the slide 66 to shift to the right.
  • the slide acts through the longitudinally stiff tape 72, the block 74 and the bracket 75 to shift the bar 77 upwardly and cause the pins 79 to move upwardly to positions unlocking the latch bolts 53 (see FIG. 14).
  • the rightwardly moving drive pin 65 encounters the outside edge of the curved portion 89 of the slot 83 in the sash arm 81.
  • the pin 65 starts turning the sash arm 81 clockwise ans starts opening the sash 20.
  • the curved portion 89 of the slot 83 turns into embracing relation with the drive pin 65 and continues to turn into embracing relation with the pin until the sash has opened through an angle of about 45 degrees as shown in FIG. 7.
  • the curved portion 89 of the slot 83 starts turning out of embracing relation with the drive pin 65 (see FIG. 8) but the pin continues to apply a turning moment to the edge of the slot and continues to open the sash until the sash has been opened through about 90 degrees.
  • the driver pin 65 When the driver arm 60 subsequently is turned counterclockwise, the driver pin 65 bears against the opposite edge of the curved portion 89 of the slot 83 and forces the sash arm 81 to turn counterclockwise to close the sash 20.
  • the curved portion 89 of the slot 83 first moves into and then out of embracing relation with the drive pin 65 as the drive pin continues to bear against the edge of the slot.
  • the pin 65 starts moving to the left in the straight portion 88 of the slot 83, the sash is fully closed and the remainder of the leftward movement of the pin acts through the slide 66 and the tape 72 to pull the bar 77 downwardly and cause the pins 79 to hold the latch bolts 53 in their locked positions shown in FIG.9.
  • FIG. 9 The specific manner in which the latch bolts 53 are unlocked is illustrated in FIG. 9 and in FIGS. 12 to 15.
  • the bar 77 is shown in the downwardmost position which the bar occupies when the sash 20 is fully closed and no further counterclockwise turning of the crank 41 is possible.
  • the pins 79 engage the vertical edges 80 of the latch bolts 53 when the bar is positioned as shown in FIG. 9 and positively prevent counterclockwise turning of the latch bolts. This defeats any attempt to open the sash 20 from the outside by pulling on the sash.
  • each pin 59 moves upwardly from the position shown in FIG. 9 to the position shown in FIG. 12 and begins to enter a notch 90 in the inner edge of the associated latch bolt 53.
  • the pin 59 is positioned as shown in FIG. 12, the sash 20 has not yet started to open.
  • each pin 59 bears against the upper edge of the respective notch 90 and starts turning the latch bolt 53 counterclockwise toward its unlocked position.
  • the sash 20 starts to open as shown in FIG. 13.
  • a curved edge 91 of the throat 54 in the bolt cams against the strike pin 58 as shown in FIG. 14 and positively forces the pin outwardly to help open a sash which might be stuck by paint or ice.
  • the torsion spring 59 forces the latch bolt to its fully unlocked position shown in FIG. 15 to free the strike pin 58 and permit full opening of the sash 20.
  • each pin 59 enters the notch 90 in its respective latch bolt 53 and turns the latch bolt clockwise.
  • the outer edge 92 of the throat 54 engages the strike pin 58 and helps draw the sash 20 inwardly to a tightly sealed position.
  • the pin 59 then leaves the notch 90 and moves into abutting engagement with the vertical surface 80 of the locking bolt 53. While in this specific instance the latching bolt draws the sash inwardly and turns to its fully locked position at the same time the sash reaches its fully closed position, it will be appreciated that the latch bolt could reach its fully locked position shortly after the sash is fully closed.
  • the apparatus requires only a single operation to unlock and open the sash 20 and requires only a single operation to close and lock the sash.
  • the task of opening and closing the sash thus is simplified and, in addition, there is less chance of inadvertently leaving the sash unlocked.

  • FIGS. 16 to 23 An embodiment of apparatus incorporating the features of the invention is shown in FIGS. 16 to 23 in which parts corresponding to those of the first embodiment are indicated by the same but primed reference numerals.
  • the apparatus of the second embodiment is particularly characterized by it ability to hold the sash 20′ very rigidly when the sash is in its open position and thereby prevent the sash from being buffeted by wind.
  • each latch 49′, 50′ includes a rotatable latch bolt 53′ adapted to be turned clockwise from an unlocked position shown in FIG. 16 to a locked position. Such turning is effected by means of pins 79′ attached to a vertical bar 77′ and operable to rotate the latch bolts in a clockwise direction when the bar is shifted downwardly.
  • torsion springs (not shown) turn the bolts counterclockwise from their locked positions to their unlocked positions shown in FIG. 16. Upward and downward shifting of the bar is effected by pushing and pulling a metal tape 72′ whose upper end is connected to the lower end of the bar by a bracket 75′.
  • opening and closing of the sash 20′ and unlocking and locking of the latch bolts 53′ are effected in response to turning of a reversible rotary actuator or crank 41′.
  • the crank is connected rigidly to the inner end portion of a spindle 42′ (FIG. 18) which is rotatably journaled in an actuator cover 43′ fastened to the sill 28′.

  • the bevel gear 100 is attached to one end of a lead screw 101 which is formed with a helical thread 102 of substantial width.
  • the right end portion of the lead screw is journaled for rotation by the actuator cover 43′.
  • Telescoped over the lead screw are two nuts 104 and 105 and an unthreaded sleeve 106.
  • the nuts 104 and 105 are formed with threads 107 and 108, respectively, (FIG. 22) adapted to mate with the thread 102 of the screw 101.
  • the nut 105 is located between the nut 104 and the sleeve 106.
  • Unlocking of the latch bolts 53′ is effected during initial movement of the nut 105 to the right along the screw 101 while locking of the latch bolts is effected during final movement of the nut 105 to the left along the screw.
  • the nut 105 includes an outwardly projecting lower flange 109 (FIG. 20) which is connected to the free end of the tape 72′ by a vertical rivet 110. As the nut 105 initially travels to the right, it pushes on the tape 72′ to cause the bar 77′ to shift upwardly and permit unlocking of the latch bolts 53′ under the influence of the torsion springs.
  • the nut 105 pulls the tape 72′ and the bar 77′ sufficiently far to cause the pins 79′ to turn the latch bolts 53′ to their locked positions.
  • the rivet 110 travels in an elongated slot 111 (FIG. 23) formed in a fixed casing 112 which is supported on the sill 28′ and which extends partially around the screw 101, the nuts 104 and 105 and the sleeve 106.
  • a shroud 113 (FIGS. 19 and 20) encloses the inner and upper sides of the casing 112 and defines a molding along the sill 28′.

  • the nut 105 is disposed within the space between the two legs of the yoke.
  • An elongated arm 116 (FIG. 17) extends between and is connected rigidly to the two legs of the yoke 115 and projects beyond the right end of the yoke.
  • a sash link 117 is connected pivotally to the right end portion of the arm 116 at 118.
  • the other end portion of the sash link is pivotally connected at 119 to a bracket 87′ secured to the bottom or the sash 20′.
  • FIGS. 17 and 21 show the position of the nuts 104 and 105 and the sleeve 106 when the sash 20′ is fully closed and locked.
  • the nut 104 is at the extreme left end of the screw 101 while the nut 105 is located immediately adjacent the nut 104 and is spaced axially from the sleeve 106.
  • the extreme left end portion 120 of the screw 101 is unthreaded and is received in the nut 104 when the sash 20′ is closed and locked.
  • the nut 105 receives the threaded portion 102 of the screw 101 but such portion does not extend into the nut 104 when the parts are located in the position shown in FIG. 21.
  • a bracket 125 at the left end of the screw prevents the nut 104 from sliding to the left off of the unthreaded portion 120.
  • unlocking and opening of the sash 20′ are effected by turning the crank 41′ clockwise, the crank acting through the gears 45′ and 100 to rotate the screw 101 clockwise (FIG. 18).
  • initial clockwise rotation of the screw 101 causes the nut 105 to move from left to right along the screw and to travel from the position shown in FIG. 21 to the position shown in FIG. 22.
  • the nut 105 acts through the rivet 110 to push on the tape 72′ and unlock the latch bolts 53′.
  • the nut 104 remains stationary during initial clockwise rotation of the screw 101 since the unthreaded portion 120 of the screw is received in the nut 104 and is not capable of advancing that nut.
  • the latch bolts 53′ are fully unlocked.
  • the nut 105 engages the sleeve 106 and forces the sleeve to move to the right along the screw.
  • the sleeve shifts the yoke 115 to the right and causes the yoke to pull the nut 104 onto the threaded portion 102 of the screw.
  • the nuts 104 and 105 force the yoke 115 to the right and act through the yoke, the sash arm 116 and the sash link 117 to swing the sash 20′ to an open position as shown in FIG. 23.
  • the screw 101 When the crank 41′ is turned counterclockwise, the screw 101 also is rotated counterclockwise and drives the nuts 104 and 105 to the left. As a result, the nut 104 acts to close the sash 20′ while the nut 105 acts through the tape 72′ to pull the bar 77′ downwardly. When the sash approaches its fully closed position, the nut 104 runs off of the threaded portion 102 of the screw 101 and returns to the unthreaded portion 120. Thus, further counterclockwise rotation of the screw produces no further closing of the sash by way of the nut 104.
  • the sash 20′ is held rigidly in all open positions of the sash.
  • the screw and the nut form a high efficiency transmission and enable the sash to be opened and closed easily when the crank 41′ is turned, it is virtually impossible for the nut to turn the screw when an axial force is imposed on the nut. As a result, the sash is held very rigidly and does not buffet under the force of high winds.
  • the apparatus of the second embodiment requires significantly fewer components beneath the cover 43′ than is the case with the apparatus of the first embodiment.
  • the cover 43′ is trimmer and more compact than the cover 43.
