WINDOW SECURITY DEVICE FOR SAFELY SECURING WINDOW
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The invention generally pertains to window security systems. More
specifically, the invention
relates to a device that can be easily installed in a window channel to safely
secure the window
when in an open or closed configuration.
(2) Description of the Related Art
Placing security devices on or within a window, or within a window frame, to
prevent unauthorized
access from the exterior of a window to the interior of the window, is well
known in the art. These
devices include vertical and horizontal bars that are permanently installed
and extend across the
window, covering either the interior or exterior of a window to prevent
passage through the
window. These devices further include security systems built into the window
sash to increase the
aesthetics of the system while still offering the requisite protection from
intruders.
While these existing devices provide the security needed to prevent unwanted
entrances through a
window, they have drawbacks. Initially, to install the devices that are
permanently installed one
must screw the device into the window sash, the window frame or even the wall.
This leaves holes
behind if the owner ever wishes to remove the device. Additionally, these
devices are not
aesthetically appeasing nor are they portable. Further, other designs only
allow the window to be
closed while the device is in place, which is not desirable in climates where
users would like fresh
air to come through the window.
Furthermore, the increase in break-ins, and child-falls has created a need for
easily securing an
open window for both events. There are ample window security bars
commercialized, but not any
portable window security solutions. It's worth noting that 'broom-stick'
window blocks are easily
defeated if the window is left open for ventilation. The challenge for a
simple-to-install design is
that it doesn't compromise security and yet is easily removed from the inside
by an adult only.
Tamper-proofing can be achieved without tools by taking advantage of the open
sliding window
and sash for support. This same design could secure windows in any orientation
and size, including
sliding patio doors.
In addition, home break-ins are known to increase significantly during seasons
when windows are
1
CA 3061258 2019-11-12

left open for ventilation. Also; sadly, accidents can occur when children lean
against open windows.
Thus, there is a need for a new design of a window security device that is
portable, does not damage
the window or its frame, the sash, or the surrounding wall, and that provides
the desired protection
while allowing the window to be at least partially opened.
BRIEF SUMMARY OF THE INVENTION
According to an exemplary embodiment of the invention there is disclosed a
device for protecting
widows. A rod secures to the window-frame corner and extends to the sliding
window with a
restrictor that limits a window to only open 10cm (4 in.) wide. When the
window is closed the
device is child-resistant to tampering and accessible for emergency release.
As the window slides
open, it covers a release tab and is tamper-resistant from the inside and
inaccessible to an outside
intruder.
These and other advantages and embodiments of the present invention will no
doubt become
apparent to those of ordinary skill in the art after reading the following
detailed description of
preferred embodiments illustrated in the various figures and drawings.

Knob-Latch Model
According to the preferred embodiment illustrated in FIGs. 12 and 13.
1. Telescoping Bar
FIGs. 12 and 13 illustrate a telescoping bar completely occupying the window
channel W1 between
3
CA 3061258 2019-11-12
KMB0001CADOO
the Sash W2 and the Frame W3, whether the window is closed or open. The Slide-
bar 3 will travel
only 10 cm W4 to allow the window to open a safe distance and block further
opening. It is worth
noting that 10 cm is the recommended maximum child-safe opening.
2. Length adjustment
To accommodate the average range of window sizes the Inner-bar 2 will slide
within the Main-bar
3 bar to adjust size. A Bar-button 4 / B1 (see FIG. 18) / Collar-clamp Cl, C2
see (FIG. 17) would
be used to secure the length W5. To add tamper-proofing, the buttons or clamps
would be designed
to face the window channel so as to be protected by it. Fine adjustment would
be provided by the
bolts in the latches below.
3. Inserting the Sash Knob-latch
In order to secure the Telescoping bar to the window sash, the Slide-bar
attaches to a screw-in Foot
5. The Sash-latch 6 is stuck vertically to the bottom of the window sash W6
with durable 3M
doubled-sided tape. The Foot inserts into the Latch by pushing it against the
Button-collar so that
the Knob-head rests in the cut-out on the Latch. The Button-collar then snaps
back into place above
the Knob-head, locking it in the latch.
4. Inserting the Frame Knob-latch
The Frame W3 side of the window would be secured with a similar latch stuck to
the bottom of the
Frame. The Main-bar has another screw-in Foot which inserts to the Frame-
latch.
5. Quick Fire-exit
Three quick intuitive steps allow the removal of the ProwLock in a few
seconds: Close the window,
push the Button-collar on the Sash-latch/ pull the Slide-bar up, push the
Button-collar on the Frame-
latch/ pull up on the Main-bar. Otherwise, the ProwLock can remain securely in
the window as it
is opened and closed.
6. Tamper-proofing for an open window
Once the ProwLock is properly in place it blocks the window sash. As the
window is opened, the
bar stays in contact with the sash and is held securely to the frame. This
tamper-proofing allows
for ventilation without compromising security or safety. The bar, plastic
Latch/Knob, Bar-button
or Collar-clamp and 3M tape would all be made from materials strong enough to
withstand
4

KMB0001CADOO
slamming the Sash against them or prying the bar out. The Buttons on the
latches would be stiff
enough that a child or burglar won't easily release them.
7. Securing a patio door
The same design and principles can also be applied to a sliding door. A larger
model would be
designed to stretch to the length needed between the frame and door.
Hook-Latch Model
According to the embodiment disclosed in FIGs. 15 and 16
1. Main bar, telescoping
Main bar (F1, Ti) will completely occupy the window channel (W1) between the
sash (W2) and
the frame (W3), whether the window is closed or open. The inner-most
telescoping piece (F2, T2)
will travel only 10 Cms (W4) to allow the window to open a safe distance and
block further
opening. 10 Cms is the recommended maximum child-safe opening.
2. Length adjustment
To accommodate the average range of window sizes the middle (F3, T3) and outer-
most (F4, T4)
bar will slide to adjust. A Button-lock (F5) or Collar-clamp (T5) would be
used to secure the length
(W5). To add tamper-proofing, the buttons or clamps would be designed to face
the window
channel so as to be protected by it.
3.Toe-Hook and Latch
In order to secure the main-bar to the window sash, the inner-most bar
attaches to a Toe-Hook (T6).
The Latch (T7) is stuck vertically to the bottom of the window sash (W6) with
durable 3M doubled-
sided tape. The ProwLock inserts into the window channel Toe first at an angle
so that the Hook
can receive the Latch. It then lays flat in the channel.
4. Foot, Shoe and Safety Guard
The outer-most bar attaches to a 'Foot' (F6). The Foot sits in a Shoe (F7)
which is stuck to the
window frame with the same 3M tape. A spring-loaded Safety-Guard (F8) covers
the Shoe to
protect the Foot. This two-handed design would make the main-bar very
difficult to remove, by a
5

KMB0001CADOO
child or an outside burglar. So, the second act to inserting the ProwLock is
to lift the Guard, slide
the Foot in the Shoe and close the Guard over the Shoe.
5. Securing an open window
Once the ProwLock is properly in place it blocks the window sash. As the
window is opened, the
bar stays in contact with the sash and is held securely to the frame. This
tamper-proofing allows
for ventilation without compromising security or safety. The bar, plastic
Foot/Toe, lever-clamp and
3M tape would all be made from materials strong enough to withstand slamming
the Sash against
them or prying the bar out.
6. Securing a patio door
The same design and principles can also be applied to a sliding door. A larger
model would be
designed to stretch to the length needed between the frame and door.
7. Quick Fire-exit
Four quick intuitive steps allow the removal of the ProwLock in a few seconds:
Close the window,
lift the Safety-Guard, slide the Foot out from the Shoe and tip the bar
attached to the Toe-Hook out
from the Latch. Otherwise, the ProwLock can remain securely in the window as
it is opened and
closed.
