Claims5
A retainer sheet for covering the top surface of a base such as a mattress and for preventing a person or object resting on the mattress from falling off, the retainer sheet comprising:
- a sheet of flexible material;
- a plurality of elongated retainers attached to the peripheral area of the sheet in the region thereof corresponding to the top surface of the base and defining a generally U-shaped restraint about a rest area of the sheet, a first one of the retainers forming the base of the U-shaped restraint for providing a foot or head restraint and the second and third ones of the retainers forming the sides of the U-shaped restraint for providing restraints along the length of the sheet and mattress;
- each retainer comprising a relatively narrow elongated strip of flexible material which is attached to the base sheet along the length of the strip to thereby define a pocket, and a relatively rigid cylinder of plastic resin material sized for removable insertion into the associated pocket;
- and
- the combination of the sheet material, the resin material and the relative cross-sectional area of the cylinder and of the pockets providing friction between the cylinder and the pocket material which permits insertion and removal of the cylinder into the pocket yet retains the cylinder when in the pocket.
A retainer sheet for covering the top surface of a base such as a mattress and for preventing a person or object resting on the mattress from falling off, the retainer sheet comprising:
- a sheet of flexible material;
- four elongated retainers attached to the peripheral area of the sheet in the region thereof corresponding to the top surface of the base for forming a generally rectangular shaped restraint about a rest area of the sheet, a first pair of the retainers forming the ends of the restraint along the foot and head of the sheet and mattress, and a second pair of the retainers forming the sides of the restraint along the longitudinal sides of the sheet and mattress;
- each retainer comprising a relatively narrow elongated strip of flexible material which is attached to the base sheet along the length of the strip to thereby define a pocket, and a relatively rigid cylinder of plastic resin material sized for removable insertion into the associated pocket;
- and wherein
- each end of the side retainers or the end retainers abuts the nearest end of the adjacent end retainer or side retainer for retaining the end and side cylinders within their respective pockets.
