A load cell apparatus comprising
- a cell block adapted to couple to a first structure,
- a mount adapted to couple to a second structure, the mount being made of a first material, the mount being formed to include a bore,
- a stud extending from the cell block, and
- a liner positioned to lie in the bore, the stud engaging the liner, and the liner being made of a second material that is more lubrous than the first material, a space being defined between the stud and the mount to permit relative movement between the stud and the mount.
A patient support comprising
- a frame including a base frame, an intermediate frame supported by the base frame, and a weigh frame adapted to support the weight of a patient, and
- a load cell apparatus positioned between the intermediate frame and the weigh frame to support the weigh frame on the intermediate frame, the load cell apparatus including a cell block supporting the weigh frame, a stud coupled to and extending from the cell block, a mount supported by the intermediate frame and including a bore, and a resilient liner positioned in the bore of the mount between the stud and the mount to transfer all force between the stud and the mount, the stud including a circular portion positioned adjacent to the resilient liner to permit the stud to move relative to the mount.
A load cell apparatus comprising
- a load cell adapted to couple to a first structure, the load cell including a load cell block and a circular portion, the circular portion having a central axis,
- a mount adapted to couple to a second structure, and
- a resilient member positioned between the load cell and the mount to transmit all force between the load cell and the mount, the central axis being perpendicular to the transmitted force.
A load cell apparatus comprising
- a load cell adapted to couple to a first structure,
- a mount adapted to couple to a second structure, and
- a resilient member positioned between the load cell and the mount to transmit all force between the load cell and the mount, the resilient member being positioned below the load cell and above the mount so that downward force is transmitted from the load cell to the mount.
A load cell apparatus comprising
- a load cell adapted to couple to a first structure,
- a mount adapted to couple to a second structure, and
- a liner positioned between the mount and the load cell, a space being provided between the load cell and mount to permit horizontal movement of the load cell relative to the mount.
A load cell apparatus comprising
- a load cell adapted to couple to a first structure,
- a mount adapted to couple to a second structure, and
- a liner positioned between the mount and the load cell, a space being provided between the load cell and mount to permit movement of the load cell relative to the mount, the space being positioned between the liner and the mount.
A load cell apparatus comprising
- a load cell adapted to couple to a first structure,
- a mount adapted to couple to a second structure, and
- a liner positioned between the mount and the load cell, a space being provided between the load cell and mount to permit movement of the load cell relative to the mount, the liner moving relative to the mount during relative movement between the load cell and the mount.
A load cell apparatus comprising
- a cell block adapted to couple to a first structure,
- a mount adapted to couple to a second structure,
- a stud extending horizontally from the cell block and having a circular portion, and
- a resilient member positioned between the circular portion and the mount to transmit force between the circular portion and the mount.
A load cell apparatus comprising
- a cell block adapted to couple to a first structure,
- a mount adapted to couple to a second structure,
- a stud extending from the cell block and having a circular portion, the circular portion being spherical, and
- a resilient member positioned between the circular portion and the mount to transmit force between the circular portion and the mount.
A patient support comprising
- a frame including a base frame, an intermediate frame supported by the base frame, and a weigh frame adapted to support the weight of a patient,
- a mattress supported on the weigh frame, and
- a load cell apparatus positioned between the intermediate frame and the weigh frame to support the weigh frame on the intermediate frame, the load cell apparatus including a load cell coupled to the weigh frame, a mount coupled to the intermediate frame, and a liner positioned between the load cell and mount to transfer force from the load cell to the mount.
A load cell apparatus comprising
- a load cell adapted to couple to a first structure adapted to support a load to be measured, the load cell including a cell block and a stud coupled to the load cell, the stud including a circular portion,
- a mount adapted to couple to a second structure, and
- a liner positioned between the load cell and mount to transfer force from the load cell to the mount, the liner being positioned between the stud and the mount, and the liner being positioned under the circular portion.
A load cell apparatus comprising
- a cell block adapted to couple to a first structure, the cell block having a longitudinal axis and first and second longitudinally spaced-apart ends,
- a mount adapted to couple to a second structure,
- a stud coupled to the first end of the cell block to extend along the longitudinal axis, and
- a liner positioned between the stud and the mount, the liner being configured to permit sliding of the stud relative to the mount.
