[0015] Referring to Figures 1 and 2, a window 10 has a frame 12 and one or more panes of glass 14, for example a sealed unit, held in a sash 16.
Sash 16 is attached to frame 12 through a hinge or pivot located on the far side of frame 12 and not visible in Figure 1. Sash 16 opens and closes through movements in the direction of arrows 18. Window 10 may be, for example, a casement or awning window. Seals 21 are compressed between sash 21 and frame 12 when sash 21 is closed. Window 10 may, or may not, have conventional locks or latches to hold sash 16 closed. The pieces making up the frame 12 and sash 16 may have various cross-sections other than shown and may be made of various materials. Sash 16 and frame 12 may be made of vinyl in which case they may be extended and generally hollow but with various internal ribs or webs.

Sash 16 and frame 12 may be made of vinyl in which case they may be extended and generally hollow but with various internal ribs or webs.
[0016] A lock 20 has a body 22 which optionally includes a first part 24 and a second part 24. Body 22 extends through the sash 16 and frame 12. A
head 28 at a first end 30 of body 22~'has edges 32 which extend beyond body 22 and bear against the outside of sash 16. Below the head 28, a portion of the body 22 passing through the sash 16 may be a smooth or threaded cylinder.
head 28 at a first end 30 of body 22~'has edges 32 which extend beyond body 22 and bear against the outside of sash 16. Below the head 28, a portion of the body 22 passing through the sash 16 may be a smooth or threaded cylinder.
[0017] A below head portion 34 may have a cross-section that is non-circular, for example square or hexagonal, to make it more difficult to rotate the body 22 by the head 28. The head 28 may also have a shape, such as a shallow dome, that is difficult to grip with tools for the same purpose. The body 22 may be press-fit or screwed into a hole 37 drilled, punched or otherwise provided in the sash 16. When the sash 16 is closed, a second end 36 of the body 22 passes through a clearance hole 38 drilled, punched or otherwise provided in the frame 12. When the sash 16 is opened, the second end 36 of the body 22 passes outwards through the clearance hole 38. When the lock 20 is engaged, a movable abutment 40 attached to the second end 36 of the body 22 bears, directly or indirectly, against the inside of the frame 12 to prevent the body 22 from passing through the clearance hole 38 and thereby preventing the sash 16 from being opened. The lock 20 may be retrofit to a window already installed, or built into a new window before installation.
[0018] The clearance hole 38 may be fitted with an optional plug 42.
The plug 42 may have a shaft 44 pressed or threaded into the clearance hole 38 and a flange 46 bearing against the inside of the frame 12. Flange 46 may help distribute forces from the abutment 40 of the lock 20 to the inside of the frame 12 if someone or the wind tries to force the sash 16 open. Shaft 44 may include a movable seal 48. For example, a seal made of fibers attached to the inside of shaft 44 is shown. Seal 48 closes some or all of the passage through the clearance hole 38 when the body 22 is removed to inhibit insect or water entry through the clearance hole 38 when the sash 16 is open, or when the sash 16 is closed if no other seal 20 is located between the clearance hole 38 and the periphery of the frame 12.
The plug 42 may have a shaft 44 pressed or threaded into the clearance hole 38 and a flange 46 bearing against the inside of the frame 12. Flange 46 may help distribute forces from the abutment 40 of the lock 20 to the inside of the frame 12 if someone or the wind tries to force the sash 16 open. Shaft 44 may include a movable seal 48. For example, a seal made of fibers attached to the inside of shaft 44 is shown. Seal 48 closes some or all of the passage through the clearance hole 38 when the body 22 is removed to inhibit insect or water entry through the clearance hole 38 when the sash 16 is open, or when the sash 16 is closed if no other seal 20 is located between the clearance hole 38 and the periphery of the frame 12.
[0019] A large percentage of windows are made within a few millimeters of a small set of distances from the outside of the sash 16 to the inside of the frame 12. Accordingly, a body 22 made in one piece or otherwise with a fixed length may be useful even when used to retrofit installed windows 10. However, body 12 may also be made to have an adjustable length. For example, the body 22 shown has a threaded bore 50 inside of first part 24 and a threaded shaft 52 extending from a second part 26. By rotating the threaded shaft 52 in the threaded bore 50, the length of the body 22 may be altered. A lock nut 54 may be tightened against the first part 24 to lock the body 22 at the desired length. Alternatively, the threaded bore 50 may have a plastic or rubber insert to grip the threaded shaft 52, chemical thread locking solutions or solder may be applied, or other means may be used to fix the length of the body 22. Other means of making the length of the body 22 adjustable may also be used. Further alternatively, one or more washers may be placed between the head 28 and the sash 16 or between the abutment 40 and the frame 12 to account for varying window thicknesses. Further alternatively, plugs 42 may be made with flanges 46 of varying thickness or one or more washers may be placed between the flange 46 and the frame 12. If a one piece or non-adjustable length body 22 is used, rotation of the head 28 does not risk lengthening the body 22. In this case, the portion of the body 22 that passes through the sash 16 may be threaded, the below head portion 34 may be round, and the second end 26 of the body 22 may be made small enough to pass through the hole 37 in the sash 16 and used to rotate the body 22 to screw it into the hole 37. A small space between the abutment 40 and the frame 12 when the sash 16 is closed, for example up to 3 mm, is acceptable if the window 10 has other locks or latches that compress the seals 20. At least one of first part 24 and second part 26 may be made of a non-metallic material, for example polycarbonate or another plastic, to provide a thermal break in the body 22.
[0020] The abutment 40 in the lock 20 of Figure 1 is cut from a plate of generally stiff but elastic material such as steel or plastic. Part of the abutment 40 is located within a slot 64 in the second end 36 of the body 22. The thickness of the abutment 40 may be slightly greater than the thickness of the slot 64 such that, while the abutment 40 may slide and rotate in the slot 64, there is some frictional resistance to these motions and the abutment 40 tends to stay where it is placed until moved again. In this way, when the abutment 40 is located to allow the body 22 to pass in or out through the clearance hole 38, the abutment 40 is unlikely to move accidentally to a position that binds in the clearance hole 38.
[0021] The abutment 40 has a slot 60 with a detent 62. A pin 66 in the slot 64 of the body 22 is slightly wider than the slot 60 of the abutment 40 except at the detent 62 and at a slot end 70. In this way, the abutment 40 resists movement from the locked position shown in Figure 1 but the slot 60 of the abutment 40 is not forced open while in an unlocked position shown in Figure 2. The width of the abutment 40 is smaller that the diameter of clearance hole 38 or the inside diameter of plug 42 such that, when the abutment 40 is slid to the left and rotated downwards from the position shown in Figure 1, the abutment 40 no longer prevents the body 22 from being removed from the frame 12. For example, the abutment 40 may be about as wide as the diameter (or maximum distance across the cross-section if not circular) of the part of the body 22 that passes through the frame 12. With either a single piece or adjustable length body 22, an abutment may be used that has, in the locked position, a variable dimension between the pin 66 and head 28 as shown for example in a third lock 20c shown in Figure 7. Using a third abutment 40c of Figure 7 to replace abutment 40 may help account for variations in the thickness of a sash 16 or frame 12 or allow the third abutment 40c to press against the'inside of frame 12 or compress the seals 21 by varying the location of the pin 62 in a third slot 60c of the abutment part 40c of Figure 7.
[0022] Figure 3, 4 and 5 show a second lock 20b. Components of second lock 20b that are similar to components of lock 20 of Figures 1 and 2 have been given the same reference numeral followed by a "b". For those elements of second lock 20b, the description for the first lock 20 applies except where inconsistent with text or Figures describing the second lock 20b.
[0023] A second body 22b of second lock 20b is a one piece construction made of a metal or plastic, for example brass, steel or a polycarbonate. A nut 80 or a threaded portion 84 is used to keep the second body 22b in the second sash 16b. If the second body 22b is metal, at least the second head 28b may be powder coated or covered, for example with vinyl, to reduce heat transfer. A spring 82 is placed over a part of the second body 22b on the opposite side of the nut 80 from the second head 28b. The spring 82 may press at one end against the nut 80 or may be stretched or threaded over a part of the threaded portion 84. In an extended position, the spring 82 extends over part of a second abutment 40b when the second abutment 40b is positioned generally in line with the second body 22b. For example, the spring 82 when extended may extend beyond a second pin 62b.
In this way, when a second window sash 16b is open, the second abutment 40b remains aligned with the second body 22b so that it can be made to pass more easily through a second clearance hole 38b. When the second sash 16b is closed, the spring 82 is compressed into a compressed position in which it bears against the second frame 12b. Optionally, the spring 82 may taper to a larger diameter where it goes over the threaded portion 84 so that the spring 82 may be narrower and fit closer over the second part 36b of the second body 22b as shown in Figure 6..
5[0024] A second slot 60b is angled relative to bearing surfaces 80 of the second abutment 40b so that sliding the second abutment 40b will account for small variations in dimensions between the length of the second body 22b and the second window 10b, or allow the second body 22b to be placed under tension. Alternatively, the spring 82 may be omitted and a high-friction, for example rubber, washer placed between the second abutment 40b and the inside of second slot 64b. This assists in keeping the second abutment 40b aligned with the second body 22b while the second frame 12b is closed but does not itself align the second abutment 40b as the spring 82 does.
[0025] A cover 88 may be placed over the second clearance hole 38b to cover the second clearance hole 38b while the second sash 16b is open.
The cover 38b is a thin plastic sheet with slits 90 to allow the second lock 20b to pass through it. An adhesive area 92 is provided for attaching the cover 88 to the second sash 16b.
[0026] While the above description provides examples of one or more processes or apparatuses, other processes or apparatuses may be within the scope of the accompanying claims;
In this way, when a second window sash 16b is open, the second abutment 40b remains aligned with the second body 22b so that it can be made to pass more easily through a second clearance hole 38b. When the second sash 16b is closed, the spring 82 is compressed into a compressed position in which it bears against the second frame 12b. Optionally, the spring 82 may taper to a larger diameter where it goes over the threaded portion 84 so that the spring 82 may be narrower and fit closer over the second part 36b of the second body 22b as shown in Figure 6..
5[0024] A second slot 60b is angled relative to bearing surfaces 80 of the second abutment 40b so that sliding the second abutment 40b will account for small variations in dimensions between the length of the second body 22b and the second window 10b, or allow the second body 22b to be placed under tension. Alternatively, the spring 82 may be omitted and a high-friction, for example rubber, washer placed between the second abutment 40b and the inside of second slot 64b. This assists in keeping the second abutment 40b aligned with the second body 22b while the second frame 12b is closed but does not itself align the second abutment 40b as the spring 82 does.
[0025] A cover 88 may be placed over the second clearance hole 38b to cover the second clearance hole 38b while the second sash 16b is open.
The cover 38b is a thin plastic sheet with slits 90 to allow the second lock 20b to pass through it. An adhesive area 92 is provided for attaching the cover 88 to the second sash 16b.
