Abstract
These bed hand rails are for use with rotatable hand grip rails on a bed. The rails comprise an arrangement of rails forming the hand grip rails, wherein the hand grip rails form an annular space; and a rigid or semi-rigid, perforated metallic cover is attached to the hand grip rails and covers the annular space. The cover has a rigidity that is substantially resistant to penetration by an appendage of a person.
Description
- This application claims the benefit of U.S. provisional patent application Ser. No. 60/756,491 filed Jan. 5, 2006.
- This invention relates to bedside handrails for hospital and nursing home beds. In the preferred embodiment, the handrail or grab bar rotates or pivots.
- Hospital beds traditionally had some type of collapsible side rail on each side of the mattress, so that a patient on the bed cannot inadvertently roll off of the bed and receive serious injuries from a fall to the floor. Padded covers, bumper wedges and the like also are used with the bed-rails to improve the comfort and safety of patients in long-term care facilities.
- One recent development is a padded gap protector that provides zero clearance no matter what the articulated position of the bed is. The pad remains in compression with the mattress and closes the gap between the mattress and side rails. The pad provides a zero gap when the mattress is in a horizontal position and when the mattress is secured in an articulate position such as an elevated position. The gapless bed rail pads are described in U.S. Pat. No. 6,347,422 issued on Feb. 19, 2002, which herein is incorporated by reference.
- Another recent development is an enabler cover for hand rails used with hospital and nursing home beds. The industry often refers to these hand rails as grab bars, positioning bars and the like. U.S. Pat. No. 6,629,325 issued on Oct. 7, 2003, which herein is incorporated by reference, discloses an enabler cover for use with hand rails on a bed which comprises a pad which fits around the rails of the hand rails. The pad, including a cover material, defines an interior space formed of the material. The material is flexible, non-abrasive and substantially resistant to penetration by an appendage of a person. The pad also includes a foam material filling the interior space defined by the cover material. Further, the cover material includes a means for enabling the enabler cover to fit around the rails of the hand rails. A mesh cover then covers any opening in the hand rails.
- The hand rails prevent, to some extent, a resident from falling out of bed. Internal bed positioning or assistance into and out of bed is the major use. Hand rails typically have a tubular frame which mounts to the bed frame. The hand rails may rotate up to 360° and lock into a number of positions. The hand rails, however, have an open center with the tubular frame circumscribing the opening. During operation or in a stationary position, a limb or other body part should not extend through the opening. As a result, a need remains for improving these hand rails.
- This invention provides yet other improvements for hand rails used with hospital and nursing home beds. Instead of a mesh cover enclosing the open center of the hand rails, I employ a perforated metal cover. The perforated metal cover may be a plate, wire mesh and the like. Unlike the flexible mesh of my previous cover, the metal cover is rigid or semi-rigid and welded to the tubular frame circumscribing the opening. The metal cover is very durable and survives the everyday use of long term care beds, yet is flexible enough to be substantially resistant to penetration by an appendage of a person.
- Instead of the tubular pad of my earlier invention, I now use a spray on rubbery material. This spray on protection provides protection cushioning yet is very durable and survives the everyday use of long term care beds.
- In my prior invention, the hand rails rotate 360° and lock firmly and safely into position with a pin and hole. Height adjustment also was carried out with the pin and hole arrangement. With time, however, the pins and holes wear and don't provide firm and safe positioning. I now use a lock bolt and lock nut assembly for rotation and height adjustment. The locking assembly is very durable and survives the every day use of long term care beds.
- Other objects and advantages of the present invention will become apparent to those skilled in the art upon a review of the following detailed description of the preferred embodiments and the accompanying drawings.
-
FIG. 1 shows a first embodiment of a perforated metal cover according to this invention. -
FIG. 2 shows a second embodiment of a rigid or semi-rigid wire mesh cover according to this invention. -

FIG. 1 showsbed hand rail 10 according to this invention.Rail 10 comprises an arrangement ofrails 12 circumscribing an annular space.Cover 14 covers the annular space and is welded to the inside edges orrails 12 defining the annular space.Cover 14 preferably is a perforated metal plate. Rubberycushion 16 is sprayed ontorails 12. -
FIG. 2 shows another embodiment forcover 14 forhand rail 10. In this embodiment,cover 14 is a rigid or semi-rigid wire mesh. - The rubbery material of
cushion 16 of this invention may vary widely. widely. Generally, it is a thermoplastic polymer produced by the condensation reaction of a polyisocyanate and a hydroxyl-containing material, e.g., a polyol derived from propylene oxide or trichlorobutylene oxide. The basic polymer unit is formed as follows: R1NHCOOR2. - A preferred urethane is RUBATEX ⅜″ WALL: FIRE RATED (ASTM E-84 ME; 25 flame or less; 50 smoke or less). The urethane generally has a density less than 0.25 lbs/ft3. Preferably, the urethanes are flame-resistant and have a low smoke value. This usually is accomplished by incorporating a metallic salt such as aluminum trihydrate. Typically, the materials should have a flame spread of 25 or less and a smoke value of less than 400 according to standard ASTM tests.
-
Rubbery cushion 16 also may comprise rubber and a resin component containing at least one ethylene-vinyl acetate copolymer (EVA). Ethylene vinyl acetate copolymers useful in the invention containing at least 15% by weight vinyl acetate. The resin component may contain only ethylene vinyl acetate copolymer or a mixture of EVA copolymers. - The rubbers, latexes or elastomers of this invention may vary widely. Examples of such elastomers include neoprene, EPDM, i.e., ethylene-propylene-diene terpolymer, SBR, i.e., styrene-butadiene rubber, nitrile rubber, and chlorinated polyethylene. Other eligible examples of rubbers include chlorosulfonated polyethylene, chlorinated polyethylene, ethylene-propylene rubber, isoprene-isobutylene rubber, chlorinated or brominated butyl rubber, and nitrile-butadiene rubber.
- Natural rubber latex for
cushion 16 can be any widely used centrifuged or creamed natural rubber latex such as NC 35% from ENNAR adjusted to the proper KOH number and PH value for proper reaction to standard curing agents and accelerators common to the trade. - Styrene butadiene rubber for
cushion 16 is a low styrene SBR type such as 27% styrene that will crosslink and cure with the same cure package as incorporated in the formulation for the curing of the natural rubber. The SBR polymer will adhere in a satisfactory manner either alone or in combination with natural rubber to the top surface ofrails 12. - The metals of
cover 14 may vary widely. Forexample cover 16 may be made iron, copper, aluminum and the like. Alloys such as carbon steels may be used as well. Molybdenum improves the toughness and wear resistance of steel alloys. Corrosion and oxidation resistance of steel is increased with the addition of chromium or nickel (stainless steel). These metals and alloys may be used in either the perforated metal plates or the wire mesh. Rigidity may be controlled by the number of holes in the plate or the openness of the wire mesh. Rigidity also is controlled by the thickness or diameter of the wire. The holes or spaces may very with caution not to make them to large. A limb or other body part should not extend through the opening. The holes or openings are such thatcover 14 is substantially resistant to penetration by an appendage of a person. -
