Abstract
A tamper indicating barrier system for a window has a barrier, such as a grill, for the window, with a barrier support for supporting the barrier adjacent the window. Springs urge the barrier away from a disturbance indicating position within the barrier support. One or more switches are switched when the barrier is moved to this disturbance indicating position resulting in an alarm.
Description
WINDOW SAFETY SYSTEM
BACKGROUND OF INVENTION
Frequent accidents are occurring where children are falling out of windows.
This may occur where a window is opened by the child, or left open by another, and any window screen does not hold when a child falls against it.
Therefore, there is a need for a safety system to guard against this kind of accident.
SUMMARY OF INVENTION
A tamper indicating barner system for a window has a barrier, such as, a grill, for the window, with a barrier support for supporting the barrier adjacent the window. Urging means, such as springs, urge the barrier away from a disturbance indicating position within the barrier support.
Sensing means, which may include switches in an electric circuit, causes an alarm to be generated when the barrier is moved to this disturbance indicating position.
Other features and advantages of the invention will become apparent from the following description, in conjunction with the drawings, BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
Turning to figures 1 to 3, a tamper indicating barrier system 10 for a window 12 has a barner in the nature of grate 14 for the window. With brief reference to figure 4, the grate 14 is seen to have six projecting feet 16: two projecting from each side and fiwo projecting from the bottom. These feet allow the grate 14 to be supported adj acent the window by a barrier support 20. The barner support 20 has left and right inner side supports 22i and outer side supports 220 as well as inner and outer bottom supports 24i, 240, respectively andl a top support 25. The outer supports 220, 24o and top suppoxt 25 are attached to the frame 26 (or an associated window ledge or sill) by, for example, screws.
As best seen in figure 2, the inner barrier supports (e.g., inner support 2;2i) and the outer barner supports (e.g., outer support 220) are notched at notches 28. Further, e~~ch of the outer supports has a tongue 30 and each of the inner supports has a corresponding groove 32.
The supports are designed so that when the tongue 30 of an outer support is inserted in the groove 32 of an inner support, the notches 28 Iine up to form foot receptors 34 (figure 1 a).
Thus, with the barrier support secured to the window and each foot of the grate received in a foot receptor of the barrier support, the grate is held adjacent the window.
As will be apparent from figure la, each foot has a certain amount of play within its foot receptor 34. A leaf spring 40, seen in figure la and 3 and detailed in $l;ure 5, is fit to each foot 16 for urging each foot away from its inner barrier support 22i or r:4i. Each inner barrier support 22i, 24i has a sensor, namely, a normally closed contact 42 proj acting into notch 28 of the support. ~If the foot 1G of the grate 14 is pushed against the contact 42 within its foot receptor 34 against the urging of leaf spring 40, the contact 42 will be forced open. As will be explained, this will result in the system alarming.
Turning to figure 7, each of the normally closed contacts 42 is part of an electric circuit 44. A
bell 46 or other alarm is connected into this circuit such that when one of the contacts is opened, the alarm alarms. The electric circuit 44 may be powered by a battery in the bell 46 or from an electrical circuit in the dwelling.
Optionally, grate 14 may be telescoping or provided with extension pieces.
Turning to figure 6, a grate 140~has extension pieces 180 and 182 which allow the width of the grate to be chosen based on the width of the window to which the grate is to be fitted.
Turning to figure 8, optionally the safety system of this invention may also be used to provide a thermal barrier. More specifically, the safety system may be used to install a plastic sheet 48 over window .12. To accomplish this, an outer edge 50 of each said inner support, e.g., 24i, and an inner edge 52 of each outer support, e.g., 240, is beveled to form a longitudinally extending triangular channel when the outer and inner supports are joined together. The plastic sheet may extend under the inner support and wrap around a rubber triangular insert 56 that is compressed between the outer and inner support 240, 24i once the outer support is mated with the inner support. This. holds an end of the plastic sheet 48 betvereen the triangular insert 56 and the edges 50, 52 of the supports 240, 24i. The inner support may have a foam pad 58 attached to its bottom to protect the plastic sheet from chaffing. Figure 8 also ilIus~trates a screw 60 which may be used to secure the outer support to a bottom ledge of the windlow.
To install safety system 10 in a window 12, an optional plastic sheet 48 may be first held against the window frame and the inner supports 22i, 24i may then be placed in the window frame over the sheet 48. The upper support 25 may next be placed over the sheet and secured to the top of the window frame. Next, the (optional) triangular inserts 56 are positioned against the outer edges 50 of the inner supports and the ends of the plastic sheet wrapped around the inserts. Feet.16 of grill 14 are located in notches 28 of the inner supports (using extension pieces 180, 182 if necessary) and the outer supports 220, 24o are then mated with the inner supports 22i, 24i to form the foot receptors 34. Lastly screws 60 may ynoor the outer supports to the window frame (or window ledges).
After installation, should a child push against the grill 14 with sufficient force to overcome springs 40, one or more feet 16 of the grill will move and depress an associated contact 42.
When the normally closed contact opens, the alarm sounds. This alerts a caregiver to the fact that the child is at the window before any harm comes to the child.
The system provides the further advantage that any burglar who attempted to gain entry through window 12 would necessarily disturb the grill 14. Most likely, this would cause one or mare of the feet 16 of the grill to push an associated contact 42 open.
A final advantage of the system is that it allows installation of a thermal barrier to the window.
The supports 22i, 220, 24i, 24o may be molded from a plastic composite;
material and be hollow inside with honeycomb shaped chambers for strength.
As illustrated in figure 9, the edges 70, 72 of the inner and outer supports may be flare outwardly so that the supports may be cut back, if necessary, to an angle which will match that of the window ledge into which the system is being installed.
Other features and advantages will be apparent to those skilled in this art and, therefore, the invention is defined in the claims.
