FIELD OF THE INVENTION
The present invention relates generally to beds for use in intensive use facilities and institutional settings such as hospitals, military housing, prisons, jails, colleges, public transportation facilities, detention centers and psychiatric facilities. More particularly, the present invention comprises a wall mounted bed that is ligature proof with no pinch points and may securely support a mattress thereon.
BACKGROUND OF THE INVENTION
Modular furniture such as beds have traditionally been attached to a floor in sleeping rooms to prevent the bed from being moved. Facilities having large quantities of people who may have special needs use furniture designed for intensive use for safely and durability. Assembled furniture may present certain hazards in use in intensive use settings where furniture components and fasteners may be removed and turned into weapons. Plastic and fiberglass construction has replaced wood and metal by its ability to be formed into three-dimensional shapes without external fasteners. Fiberglass and plastic is generally more aesthetically appealing than steel or wood, and more resistant to damage.
Beds in such settings are generally the biggest item in the room taking up large areas of floor space. The room must be configured to be large enough to accommodate the bed and allow the user to move about in the room, especially if the user is restricted to the room for long periods of time. Intensive use beds may be ballasted or bolted directly to the floor to reduce rearranging, tipping or moving. Securing or ballasting the bed to the floor reduces the safety concerns on both the visitors and staff and may result in a safer environment.
Therefore, it is desirable to provide a wall mounted bed that is ligature proof and will support the user on a mattress. The bed may be molded of plastic having a single piece molded base for attaching to a wall for supporting a mattress.
BRIEF SUMMARY OF THE INVENTION
A first embodiment of the present invention is directed to a wall mounted bed having a wall plate attached to a wall. A bed end piece on the wall plate may extend perpendicularly from the wall to support a mattress in a generally horizontal position. A ladder adapted to allow a user to climb onto the bed may be attached to the bed or the adjacent wall. The bed frame may be a flat pan, a skeletal frame or opposing brackets attached to the wall back. The bed on the frame is molded of plastic having integrally molded tubular frame work for attaching to the bed frame. Tamper resistant fasteners are disposed through fastener holes in frame and bed to hold the frame to the wall and the bed to the frame. A mattress may be disposed on top of the bed to provide a cushioned sleep surface. The mattress may be a intensive use mattress formed of plastic and having an enclosed center with vent to allow air release.
The rigid bed frame may be formed by structural members attached to and extending from the wall for supporting the bed body. The bed body may be a rotomolded hollow bed body having steel support members insert molded therein. The bed body may be adapted to attach to the frame or directly to the wall. Accessories such as storage boxes or restraints may be attached to the bed body or the bed frame. In a one piece configuration having a wall mount on the wall side and a mattress retainer on the outside, the bed frame is attached to the wall having the bed body supported thereon. In the event the ligature proof wall mounted bed is mounted in a corner having two adjacent walls, a bed support may be used to support the first end of the bed body while the integral steel support member may be attached directly to the second wall or to a wall plate on the second wall.
