Abstract
Abstract To prevent wheeled beds from rolling away when a patient attempts to climb on, an anchoring device is attached to the footboard or other convenient position. A vertical rod is slidably mounted in the casing of the device and preferably biased upward by a spring. A handle on the rod extends out through a vertical slot in the casing and may be depressed to lower the rod and turned sideward into horizontal slots to lock the rod in depressed position. A suction cup on the lower end of the rod anchors the rod and thus the bed to the floor when the handle is depressed. The device may be inactivated by turning the handle outward of the horizontal slots and lifting the rod either manually or by spring action. A hole in the suction cup is located so that when the rod is fully depressed the rubber surrounding the hole prevents air from entering the cup, but, when the rod is slightly elevated, air enters the cup through the hole, breaking the vacuum and preventing floor tiles from being pulled off the floor. The device may be attached to gurneys, wheelchairs and other wheeled equipment.

Claim 1
Independent Claim
156 words
A device to restrain unintentional movement of a bed or the like relative to the floor comprising a casing formed with a vertically extending first slot, bracket means to attach said casing to said bed, a rod vertically slideable within said casing between an operative and a retracted position, a handle on said rod extending out of said slot for manual movement of said rod between retracted and operative positions, latch means on said handle and said casing to hold said rod in operative position, and floor-engaging means on the lower end of said rod to secure said rod to the floor, said latch means comprising at least one side slot communicating with the lower end of said first slot, whereby when said rod is in operative position said handle may be turned to enter said side slot and said rod will not move to retracted position until said handle is turned to its original direction.
Claim 2
Independent Claim
156 words
A device to restrain unintentional movement of a bed or the like relative to the floor comprising a casing formed with a vertically extending first slot, bracket means to attach said casing to said bed, a rod vertically slideable within said casing between an operative and a retracted position, a handle on said rod extending out of said slot for manual movement of said rod between retracted and operative positions, latch means on said handle and said casing to hold said rod in operative position, and floor-engaging means on the lower end of said rod to secure said rod to the floor, said latch means comprising at least one side slot communicating with the lower end of said first slot, whereby when said rod is in operative position said handle may be turned to enter said side slot and said rod will not move to retracted position until said handle is turned to its original direction.
Claim 3
Independent Claim
