Description
BACKGROUND OF THE INVENTION

The present invention relates to furniture, and, more particularly, anti-ligature features and assemblies incorporated into wardrobes to thwart attempts by individuals to harm themselves by attaching ligatures to the wardrobe or configuring the wardrobe to create a ligature point.


Hanging is a common method of suicide worldwide and is ranked as a leading method used by persons attempting suicide in the United States. With this method of suicide, a person uses some form of ligature, e.g. shoe laces, electrical cords, belts, ropes, clothing, cables, etc., that is fixed both around the throat and at a ligature point. Ligature points are areas where a suicidal person can place a ligature to provide means for hanging. Individuals detained in institutional facilities are especially susceptible to suicidal attempts. For that reason, institutional facilities must take extra precautions to eliminate potential means for individual self-harm.


In special care environments and institutional settings, there is a need for furniture and room designs designed to minimize configurations or opportunities for individuals in these environments to harm themselves. Furniture meeting these needs should be constructed using durable and damage resistant materials are chosen for construction. Tamper resistant hardware should be used to prevent disassembly or partial disassembly into components that could be used to inflict self-harm or to harm others. Provisions allowing furniture to be securely attached to walls or floors to preclude tipping or movement of the furniture are essential.


Anti-ligature furniture is defined as furniture which eliminates possible points for attaching rope, wires, or cords to the furniture, which reduces the potential for attachment of a ligature which could be used for self-harm. Anti-ligature furniture for use in institutional or detention settings should contain a pick-proof perimeter sealant and form an impenetrable barrier, making concealment of contraband impossible and lessening the likelihood of furniture disassembly into potential weapons. Anti-ligature furniture must be extremely durable, breakage resistant, and capable of withstanding the wear and tear of demanding environments and continuous use in any institutional environment.


It would be advantageous to provide a ready for installation wardrobe or similar storage closet incorporating anti-ligature design considerations to minimize opportunities for a person to harm themselves using furniture once installed into a special care or institutional facility.


SUMMARY OF THE INVENTION

Accordingly, the present invention, in any of the embodiments described herein, may provide one or more of the following advantages:


It is an object of the present invention to provide a wardrobe incorporating anti-ligature design to minimize possibilities of use for self-harm.

Hardware used in construction and installation is tamper-resistant to prevent complete or partial disassembly of the wardrobe into component parts that might be used for self-harm or to harm others.


It is a further object of the present invention to provide an anti-ligature wardrobe wherein access to the interior of the wardrobe is secured by a roll-up door which eliminates ligature attachment locations afforded by conventional hinged doors. The roll-up door may further be locked into fully open, fully closed, or partially open positions to manage access to the wardrobe interior.


It is a further object of the present invention to provide an anti-ligature wardrobe including one or more pull-out storage drawers in the wardrobe interior. Access to the drawers may be managed by positioning a roll-up door to limit the drawers that may be accessed. The drawers may further be provided with locking means to allow for secure storage or to prevent drawer access except under managed supervision. Drawers are provided with anti-disconnect slides to prevent unauthorized removal from the wardrobe.

Referring to the figures, an anti-ligature wardrobe 100 suitable for institutional environments and useful for storage of clothing and other personal articles is presented. The wardrobe comprises an upstanding, generally rectangular cabinet 102 enclosing an interior space and having an opening on a front face that permits access to the interior space from outside of the cabinet. The cabinet is formed by generally spaced-apart opposing side wall panels 104, 105, a top panel 106 spanning between the side wall panels adjacent to respective uppermost ends 1042, 1052 thereof, a back panel 108 spanning between the side wall panels adjacent respective back ends 1044, 1054 thereof, and a floor panel 112 spanning between the side wall panels adjacent to respective lowermost ends 1046, 1056 thereof, and a front panel 109 spanning between the side panels adjacent respective forward ends 1048, 1058 thereof and opposite to the back panel, the front panel having an opening 110 allowing access to the interior space from the exterior of the cabinet 102.


The cabinet panels are joined using tamper-proof joining methods to prevent disassembly by an institutional occupant which could produce a ligature attachment location or allow removal of portions which could be used as a weapon or to inflict self-harm. Joining methods include blind joints in which no fastening hardware is necessary to maintain the connection, adhesives, and tamper-proof fastening hardware, such as tamper-proof screws. Assembly joints are sealed to create an impenetrable barrier at the panel connection joints and eliminate potential openings where contraband could be concealed in the cabinet joints.


The cabinet 102 is constructed from durable materials selected to withstand attempts to damage or disassemble the cabinet. Material should be water/moisture resistant and feature a smooth exterior surface for easy cleaning. Solid, composite, or laminate materials are contemplated. An exemplar material is medium density fiberboard (MDF) laminated with natural wood, vinyl, or other synthetic material. Synthetic laminates provide easy to clean surfaces that resist markings and easily allow color selection to match décor of the installation location.


The wardrobe cabinet 102 includes provisions for securing the cabinet to an adjacent wall to prevent unintentional movement, especially tipping. One exemplar provision includes one or more mounting rails 130 provided on an exterior surface of the back panel 108 placing them in adjacent contact with a wall 200. Tamper-proof anchoring screws may then be driven through the back panel and the mounting rail into the wall to engage structural members, such as a wall stud, within the wall structure. Anchorage to a floor 202 may also be utilized, though is recognized as generally being more difficult to install than a wall connection and may require more extensive repair should the cabinet need to be relocated.


The back ends 1044, 1054 of side panels 104, 105 may be extended beyond the exterior surface of the back panel 108 so that back ends 1044, 1054 are in contact with the surface of the wall next to which the cabinet is positioned. The extended portions of the side panels hide the mounting rails 130 from view and also preclude access to the space between the wall surface and the exterior surface of the back panel 108 where contraband may be concealed.


A moveable door 112 is provided to allow selective access to the cabinet interior space 116 through the opening 110. The door may be moved between opposing a fully open position (FIG. 7), a fully closed position (FIG. 5) and an intermediate position (FIG. 6) which allows limited access to a portion of the interior space from outside the cabinet.


The moveable door 112 is preferably a roll-up design to minimize spatial needs for situating the wardrobe by eliminating require swing clearance and positioning a retraction mechanism 140 and an opened door within the interior space. A roll-up door design also eliminates potential ligature attachment points created when opening a conventional swing-out door. The door has a bounding end 1122 which, as the door is repositioned, delineates the opening into areas that permit and prevent access to the interior space from the cabinet exterior. In the exemplar embodiment, door 112 opens from bottom to top.


A service panel 128 disposed in the upper extent of the interior space prevent access to the portion of the interior space where the roll-up door retraction mechanism 140 is disposed. The service panel 128 or a portion of the back panel or top panel may be configured suitable locking or similar capability to enable selective removal by authorized individuals to permit service of the door retraction mechanism and prevent access to the space by non-authorized persons.


The roll-up door is preferably fabricated from durable material to withstand attempts to breach the cabinet interior space. In the exemplar embodiment the roll-up door is fabricated from polyvinyl chloride (PVC) with an aluminum finish manufactured by Circa, model 20-5375.


The roll-up door includes a locking mechanism 120 that enables the door to be secured in at least the fully closed position (FIG. 5), a partially open position (FIG. 6), and a fully open position (FIG. 7). The locking mechanism 120 may include symmetrically located door lock devices 1202, 1204 disposed adjacent to the bounding end 1122 of door 112. Each door locking mechanism 120 preferably includes a keyed lock cylinder to improve security and to enable control and management of door positioning by administrators. In the exemplar embodiment, the door lock devices are Hafele Door Locks, Model 232.25.680 locks with locking cores.


The interior space of the cabinet may be provided with one or more slide-out drawers 142, 144 in the lower portion of the interior space. The slide-out drawers are moveable between generally opposing extended and retracted positions. The drawers are fully disposed within a portion interior space when retracted. When moved toward the extended position, a portion of the drawer projects through the opening such that a portion of the drawer is disposed outside of the cabinet.


The drawers are durable in construction and designed to support the weight of a person, even when extended. Drawer slide hardware precludes removal of the drawers without specialty tools to prevent drawer removal by institutional occupants. In the exemplar embodiment, the drawer slides are Accuride C9310E Heavy Duty non-disconnect full extension slides rated for 600 pounds. The exemplar drawers are formed from PVC and may be assembled using stainless steel temper proof fasteners.


The drawers include anti-ligature style pulls 1422, 1442, preferably in the form of indentations in the drawer front faces that may be engaged by a person's fingers to pull the drawers outwardly. The pulls 1422, 1442 may also be anti-ligature style pulls that are attached to the drawer faces 1424, 1444.


One or more shelves 126 may be provided in the interior space of the cabinet to increase usable storage within the cabinet. Each shelf 126 is fixedly connected to the cabinet in a manner that precludes removal, preferably using tamper-proof designs and/or fasteners. Access to the shelves is permitted when the door is moved to the fully opened position. Shelf access is blocked by the door when it is positioned in the intermediate position (FIG. 6) at which point the bounding end 1122 of the door is located adjacent to the uppermost drawer leaving a gap insufficient to permit access to the interior space.


A drawer locking device 1446 may be provided for one or more of the drawers to allow access control to the drawer. Access may be managed by the institution to limit access to the drawer(s) by the institutional occupant, or to provide a secure place for the institutional occupant to store valuables. One drawer is preferred to include a locking device. Access to both drawers may be prevented by positioning the door in the fully closed position. The exemplar drawer locking device is a Hafele push-button lock model 234.65.600 with a locking core.


The locking cores for the drawer locking device 1446 and the door lock devices 1202, 1204 may be keyed to allow operation by a single key to simplify administrative controls for use of the wardrobe in institutional settings.
