Abstract
An under bed scale which is comprised of a support frame, a load frame mounted on the support frame for receiving a load and for moving vertically relative to the support frame upon receiving the load, a pair of beam arms connected to the load frame to pivot about a respective horizontal axis in response to movement of the load frame, springs mounted on the support frame and secured to each beam arm to proportionally restrain movement of the beam arm relative to the support frame and a pair of means mounted on the support frame for emitting a signal corresponding to the displacement of each respective beam arm relative to the support frame.
Claims13
A scale comprising
- a support frame;
- a load frame to receive a load thereon;
- a pair of displacement transmitting members disposed at opposite ends of said support frame;
- a plurality of load flexures, each flexure connecting said load frame to a respective member to transfer the weight of a load on said load frame to said member;
- a plurality of support flexures connecting each member to said support frame to permit each member to pivot under an applied weight of a load on said load frame;
- a pair of beams arms, each arm being secured to a respective member to pivot about a horizontal axis in response to movement of said load frame;
- a pair of springs, each spring being mounted on said support frame and secured to each beam arm to proportionally restrain movement of each respective beam arm relative to said support frame;
- and
- a pair of means mounted on said support frame for emitting a signal corresponding to the displacement of a respective beam arm relative to said support frame.
A scale comprising
- a pair of platforms for mounting of the head and the foot of a bed thereon;
- each said platform including a support frame, a load frame mounted on said support frame for receiving a bed and for moving vertically relative to said support frame upon receiving the bed, a pair of beam arms, each beam arm being connected to said load frame to pivot about a respective horizontal axis in response to movement of said load frame, a pair of springs, each said spring being mounted on said support frame and secured to each said beam arm to proportionally restrain movement of each said beam arm relative to said support frame, and a pair of means mounted on said support frame for emitting a respective signal corresponding to the displacement of a respective beam arm relative to said support frame;
- and
- a single digital readout for receiving a signal from each said means of each platform and for displaying a digital value corresponding to the received signals as a measure of weight of a load on said platforms.
