Description
BACKGROUND OF THE INVENTION

(1) Field of the Invention


The present invention relates generally to window security devices, and more particularly, relating to a window security device for securing a partially open window against further opening.


(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.


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.

DETAILED DESCRIPTION

With reference to FIGS. 1-11, there is representatively illustrated a new window security device 10 that is constructed in accordance with a first embodiment of the present invention.


With initial reference to FIG. 1, the window security device 10 is shown in use with a conventional sliding window assembly 12. Representatively, the sliding window assembly 12 includes a window frame 14, and windows 16 and 18 mounted within upper and lower window channels 20 and 22. Window 16 has a window sash 76 and window 18 has a window sash 78, each supporting a respective window pane. As shown, the window security device 10 is mounted to the window assembly 12 and is suitable for securing a partially opened window 18 from opening further.


At this point, it should be noted that while the following discussion is made in reference to a window assembly having horizontally sliding windows, the window security device 10 can also be used with a window assembly having vertically sliding windows. Additionally, the principals of the window security device 10 can be adapted for use with sliding doors.


With further reference to FIGS. 2-11, the window security device 10 includes a support member 24 that is adjustable in length to extend between opposite sides of a window frame to which the window security device 10 is mounted. The support member 24 has an outer elongated tubular member 26 having a central passage 28 into which is telescoping received an inner tubular member 30. The tubular members 26 and 30 are longitudinally moved relative to one another to adjust the length of the support member 24.


A lever clamp 32 is attached to the end of tubular member 26 and operates to secure the tubular members 26 and 30 relative to one another. The particular structure of the level clamp 32 does not form part of this application and one of ordinary skill in the art is capable of selecting a suitable lever claim. Examples, of suitable lever clamps are described by U.S. Pat. Nos. 5,441,307; 5,775,352; 8,006,711 and 8,496,018, which are incorporated herein by reference in their entirety.


A pair of rectangular feet 34 and 36 are attached to opposite ends 38 and 40, respectively, of the support member 24. Foot 36 is fixedly attached to end 40 so that is conjoined with end 40. Foot 34 is movably attached to end 38 so as to telescope in a longitudinal direction outwardly from end 38. More specifically, foot 34 includes a post 42 that extends through end 38 and is captively retained for telescopic movement relative to end 38 by flanged end 44. A coil spring 46 is disposed about the post 42 and between the foot 34 and the end 38. The coil spring 46 acts to urge the foot 34 in the outwardly direction. To prevent foot 34 from rotating relative to end 38, the post 42 is keyed with end 44, as best seen in FIG. 4.


The window security device 10 further includes first and second jam arms 48 and 50 that are attached to the support member 24 and extend outwardly therefrom in a direction generally perpendicular to the support member 24. The first jam arm 48 is pivotally attached at end 52 to the outer tubular member 26 of the support member 24 by collar 54 for rotation about the support member 24. The second jam arm 50 is fixedly attached at end 56 to the outer tubular member 26 of the support member 24 at a spaced distance from the first jam arm 48 by collar 58 for conjoined movement with the outer tubular member 26.


The first jam arm 48 is extendable in length, and similar to the support member 24 includes an outer tubular member 60 into which is telescoping received an inner tubular member 62. The tubular members 60 and 62 are longitudinally moved relative to one another to adjust the length of the first jam arm 48. A lever clamp 64, similar to lever clamp 32, is attached to the end of tubular member 60 opposite of the support member 24 and operates to secure the tubular members 60 and 62 relative to one another.


Similar to the first jam arm 48, the second jam arm 50 is extendable in length and includes an outer tubular member 66 into which is telescoping received an inner tubular member 68. The tubular members 66 and 68 are longitudinally moved relative to one another to adjust the length of the second jam arm 50. A lever clamp 70, similar to lever clamp 32, is attached to the end of tubular member 66 opposite of the support member 24 and operates to secure the tubular members 66 and 68 relative to one another.


The window security device 10 further includes sash blades 72 and 74 that are slidably mounted to the jam arms 48 and 50, respectively. As shown in FIGS. 10 and 11, sash blade 72 has a relatively thin, elongated rectangular construction so as to fit in the space between facing sides of window sashes 76 and 78. Sash blade 72 is slidably mounted to the inner tubular member 62 of jam arm 48 by collar 80 for longitudinal movement in a direction toward and away from end 52 of the first jam arm 48. Collar 80 includes a lever clamp 82, similar to lever clamp 32, and operates to secure the position of the sash blade 72 relative to end 84 of the jam arm 48. Since sash blade 74 has a similar construction to sash blade 72, a separate discussion of sash blade 74 is not required for understanding of its construction and operation.


In use, it can now be understood the window security device 10 is installed on a window to by placing support member 24 within sliding window assembly 12. The rectangular foot 34 is positioned within window channel 20 and the lever clamp 32 is operated to allow the inner tubular member 30 to be adjusted so as to allow rectangular foot 36 to be positioned within window channel 22. When the support member 24 is securely disposed between the window tracts 20 and 22 of the window frame 14, the lever clamp 32 is closed, securing the inner tubular member 30 to the outer elongated tubular member 26.


It is important to note, when the support member 24 is installed as described, the lever clamp 32 is positioned such that the lever of the clamp is facing the window 16, as shown in FIG. 7, in order to prevent someone from tampering with the window security device 10.


To adjust the distance the sliding window 18 is to remain open while the window security device 10 is in use, the length of sash blades 72 and 74 must be adjusted. To adjust the length of sash blade 72 of first jam arm 48 lever clamp 82 is operated to slide collar 80 along the inner tubular member 62 until the desired distance 73 between the arm end 84 and the end of sash blade 72 is achieved. The desired distance 73 is equal to the distance sliding window 18 can safely be opened without fear of unwanted intrusion. Since sash blade 74 is adjusted similar to that of sash blade 72, a separate discussion of adjusting the length of sash blade 74 is not required for understanding the operation of adjusting sash blade 74.


Depending on the distance between support member 24 and window sash 76, the first and second jam arms 48 and 50 must be adjusted to ensure the window security device 10 is securely installed. The window security device 10 is properly installed when the sash blades 72 and 74 extend to and abut window sash 76. The sash blades 72 and 74 should not extend beyond window sash 76. Because the first jam arm 48 and second jam arm 50 are similarly adjusted, a discussion of the first jam arm 48 is only required.


To ensure sash blade 72 is properly located along stationary window 16, lever clamp 64 is operated to allow the inner tubular member 62 to extend away from the support member 24 until sash blade 72 abuts window sash 76. Lever clamp 64 is then operated to lock the inner tubular member 62 relative to the outer tubular member 60, thereby fixing the length of the first jam arm 48. When installed, it is important to note that lever clamps 64 and 82 are disposed between the first jam arm 48 and window 16 to prevent tampering.


An important feature of window security device 10 is the ability for window security device 10 to quickly be removed in case of an emergency, such as a fire, that requires a quick-exit through a window that equipped with the window security device 10. During an emergency, one simply ensures sliding window 18 is in the closed position. The first jam arm 48 is rotated about support member 24. The support member 24 is then tilted away from the window frame 14, toward the sliding window 18, thereby removing the rectangular foot 34 from the window tract 20, which allows the window security device 10 to be removed from the sliding window assembly 12. Thereby allowing the sliding window 18 to open in its entirety and a safe passage through the window.


Referring now to FIGS. 12 and 13, there is shown therein a window security device kit 86 in accordance with an embodiment of the present invention. The kit includes 86 a first, second, and third pipe section 88, 90, and 92. Each pipe section having respective first and second ends 88a, 88b, 90a, 90b, 92a, 92b. The first and second pipe sections each having a rectangular foot 110 and 112 fixedly attached to the respective first end 88a of first pipe section 88 and to the second end 90b of the second pipe section 90. The kit 86 further includes a two pipe tees 94 and 96 and two tubular arm sections 98 and 100 each having a sash blade 102 and 104 attached to the arm section 98 and 100 by a slip-on coupling 106 and 108.


When assembled, pipe tee 94 receives and connects the second end 88b of the first pipe section 88 to the first end 92a of the third pipe section; and pipe tee 96 receives and connects the second end 92b of the third pipe section 92 to the first end 90a of the second pipe section 90. Further, tubular arm section 98 and 100 are perpendicularly connected to pipe tee 94 and 96 at ends 98a and 100a, respectively.


The distance between rectangular foot 110 and the rectangular foot 112 should be equal to that of opposing sides of window frame 14. To achieve the correct distance, pipe sections 88, 90, or 92 can be trimmed at ends 88b, 92a, 92b, or 90a. Additionally, when properly sized, the sash blades 102 and 104 of the assembled window security device kit 86 should abut the sash of the stationary window, opposite to that of pipe tee 94 and 96. To ensure the assembled kit 86 is sized properly, tubular arm sections 98 and 100 can be trimmed at ends 98a and 100a.


In an exemplary embodiment, a window security device has a support rod capable of securely contacting an upper window frame and a lower window frame. The device has two horizontal arms extending from away from the support rod terminating in thin blades capable of sliding between a first stationary window and a second sliding window sash. The device prevents unwanted tampering with the device by children located on the inside of the window as well as burglars located on the exterior of the window and to be easily removed in the event of a fire. The length of the device's blade can be adjusted allow a window to safely remain open a specified distance, and the device's arms can be adjusted to fit many different widths of windows. When the blades are disposed between the windows, the window is slid open and contacts the window stop, located at the end of the horizontal arms.


Although the invention has been described in connection with preferred embodiments, it should be understood that various modifications, additions and alterations may be made to the invention by one skilled in the art without departing from the spirit and scope of the invention.


Functions of single modules may be separated into multiple units, or the functions of multiple modules may be combined into a single unit. All combinations and permutations of the above described features and embodiments may be utilized in conjunction with the invention.
