Bed
This invention relates to a bed for accommodating heavy persons. The bed is particularly for use in hospitals, where heavy patients have to be treated. The invention provides a bed comprising a frame; a central support section mounted on the frame; two opposite end support sections, one being a head section and the other being a foot section, each mounted for pivoting movement relative to the central section; and drive means for driving the end support sections for pivoting movement relative to the central section; wherein the foot section has a platform which extends at an angle to the plane of the section, and the foot section can pivot to a position where the platform is substantially at ground level. In a particularly preferred embodiment the central section is mounted for pivoting movement about a pivot axis at or near to its edge adjacent the foot section and further comprises drive means for driving the central support section for pivoting movement about said pivot axis.
1. A bed for heavy persons, the bed comprising
a frame comprising a base and an upper frame;
a central support section mounted on the frame;
two opposite end support sections, one being a head section and the other being a foot section, each mounted for pivoting movement relative to the central section; and in which the central support section is supported on the upper frame and is mounted for pivoting movement about a pivot axis at or near to its edge adjacent the foot section; and
first drive means for driving the head section for pivoting movement relative to the central support section;
second drive means for driving the foot section for pivoting movement relative to the central section;
third drive means for driving the central support section for pivoting movement about said pivot axis; and
fourth drive means for driving the central support section wherein a scissor mechanism works between the base and the upper frame, and the fourth drive means is arranged such that extension of the fourth drive means operates the scissor mechanism and raises the upper frame whilst maintaining the base and upper frame parallel to one another; and
wherein the foot section has a platform which extends at an angle to the plane of the section, and the foot section can pivot to a position where the platform is substantially at ground level.
2. A bed according to claim 1 , in which the platform is retractable or removable.
3. A bed according to claim 1 , in which the platform has legs which can be inserted into or removed from sockets permanently attached to the foot section.
4. A bed according to claim 1 , in which the platform makes an angle of between 90° and 120° to the foot section.
5. A bed according to claim 1 in which the drive means comprise hydraulic piston/cylinder units.
6. A bed according to claim 1 in which the drive means are electronically controlled from a single control unit.
