Description

- I - The present invention relates to a locking device

  window and more particularly to such a locking device which ensures sequential locking at multiple points

  of a mobile chassis on a frame. In addition, the ver-

  window rust ensures improved locking at each point

lock.

  The movable windows that are generally used have a movable frame which is either sliding, sash or pivoting, the latter type comprising horizontally pivoted windows and vertically tilted windows.Many different forms of locking devices window are available

to block a movable window.

  The inventors described here sell window locking devices for such movable windows. In many cases, the window may be of such dimensions or made of a structural material such that it may be desirable to provide locking at multiple points. It is known to mount individual window locking devices in

  spaced points or places on the window to ensure such ver-

  rusting at multiple points. Normally, each of the window locks operates independently. However, the movable mechanisms of a pair of window locks can be connected to each other for simultaneous movement controlled by a single handle, as illustrated in the United States patent. 'America n 4.095.829 (Van Klompenburg),

  this patent belonging to the applicant.

  Multiple point locking is illustrated

  in U.S. Patent No. 2,114,645 to Van Benschoten.

  There are multiple point window locking structures,

2 6 4 1 8 1 5

  -2- available on the market, can be controlled by a single handle. The prior art does not disclose a structure ensuring sequential locking of the multi-point locking structure to ensure delayed locking allowing to take into account warped or twisted windows, and moreover these structures

  do not have a window lock designed to counteract flexi-

  bility of the window structure, as can be encountered with

a vminyle window.

  A main characteristic of the invention is to provide a window locking device, having improved locking functions for blocking a movable frame on a frame, and it relates more particularly to a window locking device constructed for blocking at multiple points so as to lock a chassis

  mobile on a frame in spaced locations, and this with a

  delayed rusting of one locking structure with respect to the other to take into account warped or twisted windows, the structure also taking into account other considerations which may intervene in the locking of a window having a certain bending,

  as in the case of a vinyl window.

  Additional features of the invention relate to the versatility of the window locking device, ensuring a simple and selective assembly of component parts to ensure the desired number of locking points; ensuring that the window locking mechanism cannot be moved by any force applied to it, other than by a control handle; sealing a window lock device housing on the frame to make it

  light, water and air tight; and an arrangement of mechanics

  operating mechanism which can be controlled by the handle, so that the latter can have two limit positions in one of which the handle establishes a locking state of the window with the handle close to the frame, while in the other limit position, the window is unlocked, and the handle has moved in an arc approaching 180, position in which the handle is arranged in a limited projection towards the outside of the housing when

the window is unlocked.

  An object of the invention is to provide a new and improved window locking device.

  Another object of the invention is to provide a provision

  new and improved multi-point window locking device, more particularly such a window locking device for

vinyl windows.

  Another object of the invention is to provide a provision

  locking device for a window comprising a window frame and a movable frame, comprising a slide comprising a cam element, a ramp bar, and means for moving the

  coulhsseau following a course extending in its longitu-

  dinal to bring the cam point to cooperate with the ramp bar to establish a locked state or an unlocked state of the window, this device being characterized in that it comprises: a locking in multiple points of the movable frame on the frame by the use of at least two of the ramp chin rests and two of the cam elements each of these ramp chin rests having an inclined ramp section and a generally planar section, the slide having a length of movement along the aforementioned route , which is greater than what is required to move a cam member along this ramp section and over the generally planar section of a ramp bar, so that delayed locking of a cam and an associated ramp bar can be reached with respect to the other cam element and the other ramp bar, by having these ramp bars located at a distance apart t of each other which is greater than the distance between the cam elements, and a planar section of a ramp bar having a length greater than the aforementioned difference in

the distances.

  Yet another object of the invention is to provide a window locking device for a window comprising a window frame and a movable frame, comprising a slide comprising a cam element, a ramp bar, and means for moving the following slide a course extending in its direction

  longitudinal to cause the cam element to cooperate with the men-

  ramp cap to establish a locked state or an unlocked state of the window, this device being characterized in that it comprises: a housing; a handle rotatably mounted on this housing in view

  displacement between two limit positions which can be com-

  mandated to move the aforementioned slide along the aforementioned path, the slide and the handle comprising cooperating elements to prevent gravity or another external force moving the

  coulhsseau along the above course without moving the handle.

  A further object of the invention is to provide a window locking device for a window comprising a window frame and a movable frame, comprising a slide comprising a cam element, a ramp bar, and means for moving the slide along a course extending in its longitudinal direction in order to bring the cam element to cooperate with the

  ramp bar to establish a locked state or an unlocked state

  rusted out of the window, this device being characterized in that each of the cam elements and of the ramp bars is bevelled to resist any separation movement taking place in the direction perpendicular to the aforementioned course due to the flexibility of the frame and movable frame, which can result from high loads. The invention will be described more fully below

  with reference to the nonlimiting drawings attached.

  Figure 8 is a fragmentary elevation view

housing.

  Figure 9 is an elevational view of the handle.

  The window lock is shown

  felt in its association with a window by Figure 1, the only parts visible from the living room being a housing 10

and a handle 12.

  The window has a frame generally designated by 14, in which the movable frame, designated by

  generally by 16, a 6-sash window is pivotally mounted

  seriously. The mounting of such a window by means of hinges is

  well known in practice, as well as the use of a device for

  window command, generally designated by 18, this device being designed to move the movable frame between a closed position and a fully open position or by bringing it to any position

  what desired intermediate position.

  As will be readily understood, the window locking device can also be used on a window of the tilting type, in which the pivoting movement of the 6-frame is generally made around a horizontal axis rather than along the vertical axis of the casement window. The concepts embodied in the window locking device could be used with other types of movable windows, for example in the case of a hung window. The window locking device is of particular interest with a vinyl window, an embodiment of such a vinyl window being shown partially in Figures 4 and 5. The frame 14 has vertical wall sections 20 and 22 suitably connected together to form a single piece, by interconnection walls. a pair of interconnected walls 24 and 26 extending at right angles to the previous wall sections, the wall 26 forming the surface of the

  sleeping facing towards the living room.

  The movable frame 16 has a vertical outer wall 28 with which walls are associated, forming only one

  part with this wall 28, in particular a wall 30 extending perpetually

  specifically to this wall 28 and forming one of the walls cooperating with the panel with vertical face 32, which can be brought into a 2G position very close to the vertical wall of frame 24 when the

  window is closed, a suitable bead 34 ensuring a tight seal.

  The window lock includes

  a slide 40 movable along a path extending longitudinally

  Lement and which includes an element operating as a cam, in the form of a roller 42. The slide 40 is movable along this path

  due to its mounting on a flat part of a support 44 which comprises

  carries a pair of shoulder rivets 46 and 48 extending through corresponding buttonholes 50 and 52 of the slide and which allow movement of the slide from the unlocked position of the window, illustrated by Figure 2, towards the position

  to block this window, illustrated in Figure 3.

  The support 44 comprises a pair of support flanges 54 and 56 arranged perpendicular to the flat part of this support and which can receive a pair of fixing devices 58 and 60 which are screwed into a pair of alignment bosses 62 -7- and 64 extending inwards from the housing 10, and which fit into a slot formed in the walls 24 and 26 of the frame. The inner face of the housing 10 extends beyond the perimeter of the opening of the frame to abut against the inner face oriented towards the part of the vertical chassis wall 26. The fastening devices 58 and 60 can attract the edges of support 54 and 56 against the internal face of Ja paroJ of chassis 24 and the perimeter of the housing 10 against the wall 26 to capture the frame between them. The perimeter part of the housing, which bears against the wall 26, comprises a continuous toric groove, parts of which are illustrated at 66

  and 68 and which receives an O-ring element to make a light seal.

  air and water tight, between the accommodation and the frame.

  The housing 10 receives the handle 12 in rotation

  to allow the displacement of the latter between two limit positions.

  One of these limit positions is the window locking position, as illustrated in Figure 3, where the handle 12 extends downward and, generally, parallel to the wall 26 of the frame . The handle can move to its other limit position, as illustrated in Figure 2, which is the unlocked position of the window. This movement of the handle is done in an arc approaching 180, so that this handle, as seen in Figure 2, barely extends beyond the housing 10 and, therefore, does no protrusion inside the room when the window

is open.

  The slide 40 and the handle 12 comprise a means cooperating so that the rotation of the handle gives a linear movement of the slide along the longitudinal path of the latter. This cooperating means comprises a drive rod keyed onto the handle at the location of its axis of rotation and which comprises a pin 72 which cooperates with a fork section of the slide. This forked section has two teeth 74 and 76 having between them an open end slot. When the window locking device is in the locked position and when the handle 12 is in the position illustrated in Figure 3, this handle can be caused to rotate in the direction

2 6 4 1815

  reverse from that of clockwise to the position illustrated in Figure 2 and, during this rotation, the pin 72 will move sequentially inwards and outwards from the slot and in cooperation with tooth 76 to move the slide 40 downwards, as can be seen by considering Figures 2 and 3. When the handle 12 returns to the position of Figure 3, this handle 12 is caused to rotate in a clockwise direction shows and the spindle 72 moves sequentially inward and outward from the slot and cooperates with an edge of the tooth 74 to raise the slider, as illustrated in Figures 2 and 3. The part plane of the support 44 has a curved cutout to allow the free end of the drive rod

  to move between the positions illustrated in Figures 2 and 3.

  The ends of the teeth 74 and 76 of the forked section of the slide are bevelled to allow movement of the drive rod 70 towards an articulation position in one or other of the limit positions of the handle. This is illustrated schematically in Figures 6 and 7. When the handle 12 moves to the unlocked position of the window of Figure 2, the drive pin 72 moves in the opposite direction to that of clockwise , as shown in Figure 6, and the arc descending to an articulation position is allowed thanks to the bevelled end 82 of the tooth 76. The pin 72 has reached an articulation position in which, if a force towards the top

  is exerted on the slide 40, as indicated by the up arrow

  dante, the beveled end 82 of the tooth 76 cooperates with the pin 72 and tends to move this pin to the right. This movement

  is prevented by cooperation between the housing and the handle.

  This cooperation is achieved by the structure illustrated in Figures 8 and 9. Figure 8 shows a side wall 83 of the housing 10, having an opening 84 for receiving a rod 85 (Figure 9) of the handle 12. A pair of stops 86a and 86b are provided on the housing to define the limit positions of rotation of the handle 12 by cooperation with a rib

  handle 87 curve. The rib 87 has an included arc of

  9- around 104, although this figure is not intended to be limiting,

  and the stops 86a and 86b are spaced apart by an angular distance of

  about 250, so that the handle can rotate in an arc of about 150. A similar articulation position is reached when the handle 12 is in the locking position of the window. As illustrated in Figure 7, any downward force applied to the slide 40, as shown by the downward arrow, will cause a beveled end 88 of the tooth 84 to cooperate with the drive spindle 72 and push the drive rod 70 clockwise,

  and as indicated by the arrow, which will be prevented by the cooperation

  ration between the handle 12 and the housing 10. The slide 40 cannot be moved by any external force other than

by moving the handle.

  The cam element mentioned above, located on the slide 40 and which is constituted by the roller 42, cooperates with a ramp bar 100 which is mounted by suitable means on the vertical wall 30 of the movable frame. The ramp bar has an inclined ramp section 102 and a generally planar section 104. The ramp bar 100 is illustrated in Figure 2 with respect to the roller 42 when the movable frame is not fully closed. In the case of a rotation in the direction

  clockwise from handle 12 to the position of ver-

  rusted illustrated in Figure 3, the slide 40 moves upwards and the roller 42 comes into contact with the inclined ramp sections 102 and rolls along these to attract and keep the movable frame fully closed when the roller 42 moves

  on the generally flat planar section 100 of the ramp bar.

  The ramp bar can be a solid element, as illustrated,

  or it can be shaped from a metal sheet.

  In order to achieve multiple point locking, the movable frame comprises a second ramp bar 110 of the same construction as the ramp bar 100 and located at a certain distance from it. A second cam element, -10-

  in the form of a roller 112, cooperates with the ramp bar 110.

  This roller 112 is rotatably mounted on a bracing bar

  114 which is connected to one end of the slide 40 for a displacement

  longitudinal cementing therewith. An upper end of this bracing bar is movable inside a guide 116 which

  is fixed to the chassis wall 20 by fastening devices 118.

  The versatility of the location of the verification points

  rusting is ensured by the way in which a

  wall 114 can be associated with coulhsseau 4 '.

  The bracing bar 1l4 has a button-

  niere 120 at its lower end, this buttonhole extending in the longitudinal direction of this bracing bar. A spacer bar rivet 122 is fixed to an offset upper end of the slide 40 and it has a pair of aligned ears located at a certain distance from the slide. When the bar

  bracing 114 is at an angle to the runner

  bucket, slot 120 can be aligned with the aligned ears of the

  rivet of the bracing bar, and this can then be moved

  cee beyond the ears, and then rotated, to an alignment position, in which the aligned ears then block the bracing bar 114 relative to the slide. There is also a strut bar rivet 124 at the lower end of the slider. The bracing bar 114 can thus extend towards

  the bottom from slide 40. Two bars can be used

  toisement. Other variants can be provided by using additional rollers with each spacer bar (and additional ramp bars), and by using bars

  bracing of variable length.

  The locking in multiple points is obtained with a delayed blocking of the roller 112 and of the ramp bar 110 with respect to the roller 42 and to the ramp bar 100, by the fact that the slide has a length of movement along its path which is greater than what is required to move a roller along the inclined ramp section 102 and on the generally planar section 104 of a ramp spike and by the fact that the spurs

- I -

  with ramp are at a distance of difference which is greater than the distance between the rollers. A generally planar section of a ramp bar has a length greater than the differences between the distances to ensure a stop for one roller while the other roller is on an inclined ramp section. An additional feature which is a

  particular use for a vinyl window due to its flexibility

  bility is the beveling of the rollers 42 and 112 and of the generally planar sections 104 of the ramp bars, as can be seen I O in FIGS. 4 and 5, and this in order to resist a separation between

  them in a direction perpendicular to the path of the slide 40.

  If we refer in particular to Figure 4, any trend

  of the movable chassis to move to the left, which could pro-

  evoking a separation between the ramp bar and the roller, is

  thwarted by the beveled relationship that exists between them.

  The sequential locking action at multiple locking points has an additional advantage in that it limits the maximum amount of force required at any time.

  given to achieve complete window locking.

  Considering the above, it will be obvious that a window locking device of very great versatility

  and ensuring blocking at multiple points was thus planned.

  When the structure of the ramp bars includes

  carries the elongated sections, of generally flat appearance, ensuring a stop there is a better versatility in the sense that the ramp bars can be located in a desired position to arrive at the desired sequence of locking at various blocking points. The bracing bars can be provided in different lengths

  and with different numbers of rollers, and the spacer bars

  can be easily associated with the slide at the top or at the base thereof, with the simple rotational connection which does not require the use of any screws to attach between the

  bracing bar and slide.
