2. Description of the Related Art
Burglaries and home invasions within residential neighborhoods have become increasingly common. The safety of an individual at home during such a burglary or home invasion can be extremely important. Law enforcement agencies generally recommend that individuals that are at home during a home invasion or an attempted burglary remove themselves from direct contact with the intruders, either by exiting the home or positioning themselves in a locked and safe room within the home. Confronting the intruders, especially by surprise, is generally discouraged.
In many cases, an intruder in a burglary or home invasion is positioned so as to block any exit by the individual at home seeking to distance themselves from the intruder. In many cases, therefore, the only alternative for an individual subjected to a home invasion is to identify a safe location and place themselves in a locked room within a home. While some efforts have been made to create safe room environments within an existing room of the home, such efforts frequently fail because of the obvious ability of the intruder to immediately detect a locked door or other barrier and take steps to either break the door down or otherwise break into the safe room, even if only for the purpose of theft of property.
It would be desirable, therefore, to have a safe room environment within a residential dwelling that is not subject to easy breach by a burglar or other intruder. It would be desirable if such a safe room environment were not immediately apparent to an intruder moving through the home, such as would be apparent when encountering a locked door. It would further be desirable if such a safe room environment were remote from easy access by the intruder.
The present invention therefore provides a system and method for establishing a safe room environment within an attic space utilizing a typical folding attic stair assembly. The system includes a kit of components that may be retrofit to an existing folding attic stair assembly in a manner that allows the user to draw the attic stair up behind them and to secure the attic door panel closed and locked while the user is within the attic space. The system components include a retractable lift cord preferably attached to the middle section of the folding attic stair, as well as a lift rod attached to the door panel of the attic stair. Brackets and frames positioned on the attic stair door panel and box door frame allow the user to pull up on the attic stair so as to fold and raise the stair into the attic space once the user has positioned themselves in the attic. A locking mechanism positioned on the attic stair door may then secure the attic stair closed, preventing access from below. Methods for installing the system and using the system are provided.
Reference is made first to
Connecting top stair section 16 with middle stair section 22 is upper folding hinge 20. In a like manner, connecting middle stair section 22 and lower stair section 26 is lower folding hinge 24. These hinges are arranged on the stair sections in a manner that stacks the stair sections together when collapsed for clearance within a folded position up into attic stair box frame 12. Each of the stair sections 16, 22 & 26 incorporate a number of stair steps 28. The placement of the various components of the safe room system of the present invention, are shown as positioned on the various existing components of the folding attic stair assembly.
Positioned in the attic on attic stair box frame 12 is attic support frame 30 which, in one embodiment of the present invention, comprises a tubular railing structure. Attic support frame 30 is fixed to attic stair box frame 12 to provide a measure of safety for the user when working above the folding attic stair assembly while in the attic, and more importantly providing a point of support for a number of the components of the safe room system once installed on the attic stair assembly. Top section lift rod 34 combined with top section lift handle 32 are slidingly connected to attic support frame 30 at lift rod slide bracket 35. The opposing end of top section lift rod 34 is pivotally attached to attic door panel 14. Top section lift rod 34 and top section lift handle 32 are used to finalize the retraction of folding attic stair assembly as described in more detail below.
Additionally shown in
The final installed component of the safe room system of the present invention comprises a door panel lock/latch assembly made up of door panel lock/latch ring 46 positioned on attic stair door panel 14 and box frame lock/latch plate 48 positioned on attic stair box frame 12 as shown. When the folding attic stair assembly is fully retracted into the stowed attic position, the assembly may be locked into place from above utilizing the door panel lock/latch assembly.

Insofar as top section lift rod 34 is rigid, it will extend up into the attic space above attic support frame 30 as shown in
With the attic stair assembly fully retracted into attic stair box frame 12, closing attic stair door panel 14, the user then moves around attic stair box frame 12 to a position where box frame lock/latch plate 48 may be pivoted down onto door panel lock/latch ring 46. In the typical lock/latch assembly, ring 46 may be turn to fully secure the lock/latch components. In this manner, attic stair door panel 14 is locked in place and may not be opened from below. Further security of the lock/latch system may be gained by adding a padlock or other key lock component to the latching mechanism.
The process of lowering of the attic stair assembly is essentially the reverse of the process shown in

The user then assembles the lift rod and the lift handle at Step 106. In one preferred embodiment of the present invention, lift rod is made up of three or more snap together sections, one of which may include the lift handle. These snap together sections allow the installation kit to be packaged in a smaller configuration with the longer rigid lift rod components being removably connectable together to form the necessary long rigid rod for operation of the system.
The lift rod as assembled is positioned in the slide bracket on the attic support frame at Step 108. The opposite end of the lift rod is pivotally secured to a point on the top of the attic door panel, preferably nearest the lowest step on the section at Step 110. The lower end of the lift rod is positioned on the outside of the ladder frame component of the top stair section so that it again may be raised into the attic space without interfering with the closure of the overall attic stair assembly.
At Step 112 the retractable lift cord component is secured around the lowest step of the middle stair section and pushed to one side so as not to interfere with the use of the step. The installation kit should include the attachment surfaces for positioning the cord reel on the middle stair section already in place on the cord reel itself. An adhesive film should be removed from the attachment surface that is to be secured to the middle stair section, and at Step 114 should be positioned in place on the inside face of the middle stair section immediately above the step where the lift cord end has been secured at Step 112. At Step 116, therefore, the cord reel itself may be secured in place on the attachment surface by the removable placement of the components associated with the Velcro® like materials.
The lowering cord is looped around and clipped in position on the middle step of the lower stair section at Step 118. This lowering cord is pushed to one side, again to prevent all obstruction with the use of the step. At Step 120 the lock/latch ring assembly is secured to the attic stair door panel aligned in a place that does not interfere with either the raising or lowering of the panel. The installation should be at an accessible location when aligned with the lock hinge plate positioned on the stair box frame. The lock/latch hinge plate is secured at Step 122 to the stair box frame in a manner that aligns with the lock/latch ring positioned on the attic stair door panel.
Once all of the components have been installed as described above, the user should test the movement, clearance, and security of all the system components individually at Step 124. Again, the various straps positioned on the steps should be moved to one side so as to not obstruct use of the steps under normal operation and the cord reel should be securely (but removably) placed at an inside location on the middle stair section where it can be easily removed and carried up into the attic during use. The attic support frame should be secure in its position within the attic stair box frame, as should the lift rod and lift handle assembly positioned thereon. Easy movement of each of these components should be operable (Step 126) by way of the generalized placement of the components as shown in the Drawings.

Step 144 sees the process of stacking the middle and lower stair sections onto their stowed position on top of the top stair section, having pivoted and folded into this parallel orientation, as is typical. At Step 146 the user releases (unlocks) the cord reel and allows the spring loaded function of the cord reel to draw up most of the slack in the cord reel, leaving just enough of the cord extending from the reel to allow the user at Step 148 to again lock the cord reel and drape it over the cross member of the attic support frame.
The user then, at Step 150, switches attention to the top section handle and lift rod and draws the two components up, sliding the rod through the slide bracket attached to the attic support frame. This draws the stacked stair sections up into the attic space and closes the door panel. The user then moves around in the attic space to the side of the attic stair box frame where the lock/latch assembly components are positioned. At Step 152 the user moves the box frame lock/latch plate down over the aligned door panel lock/latch ring and turns the ring to lock and secure the two components together. This prevents the door panel from being pulled open from below. Optionally, at Step 154, the user may secure the lock/latch assembly components with an additional key locked device such as a padlock or other locking mechanism. Those skilled in the art will recognize that other types of two part locking mechanisms may be used in place of the structural lock/latch assembly described herein. This overall process then terminates at Step 156 with the establishment of the safe room environment in the attic space.
Reference is finally made to
The user then moves back around to a position above the attic stair box frame where the cord reel may be grasped and unlocked at Step 168 and the top section lift handle and top section lift rod may be pushed downward at Step 170 to lower the stacked assembly of stair sections. The user directs the stacked assembly downward, opening the attic stair door panel by means of pushing downward on the top section lift rod, using the top section lift handle, again, in a manner the reverse of that described above. Once the stacked assembly of stair sections has been lowered to its initial position with the attic stair door panel open (as shown in
Although the present invention has been described in conjunction with a number of preferred embodiments, and has been described as being installed on one particular type of attic stair assembly, those skilled in the art will recognize variations in the components of the system that may be made for different attic stair folding structures. Specific placement of the retractable lift cord, as well as the lift rod and handle, are anticipated with variations in the geometry and size of the attic stair. Further variations in the placement and type of the locking mechanism for securing the attic door in place from above are also anticipated. The methods of installation will vary according to the specific components utilized in the establishment of the safe room environment as well as the specific structure and geometry of the attic stair. Such variations dependent upon the structure and geometry of the attic stair, and the attic environment itself, are considered to still fall within the spirit and scope of the invention as defined by the appended claims.
