Abstract

A weight scale for a gas cylinder with an impact resistance system has a rotatable top housing and a bottom housing, which is located opposite the lower surface of the top housing. The top housing has a top protruding portion that protrudes toward the bottom housing and a caster bearing that is rotatably mounted on the lower surface of the top housing. The bottom housing has a caster ramp provided on the upper surface thereof such that the caster bearing can roll down the caster ramp when the top housing is pushed down and rotates with respect the bottom housing. A weight sensor is placed on the upper surface of the bottom housing adjacent the ramp. The weight sensor is configured to measure the weight of the gas cylinder when the caster bearing rolls off the caster ramp and onto the weight sensor.

Dependent claims

A weight scale for a gas cylinder comprising:

a first housing with a facing surface;
a second housing, which is located opposite the first housing when the weight scale is assembled and having a facing surface that faces the facing surface of the first housing, said first and second housings being rotatable with respect to each other;
at least one caster bearing rotatably mounted on the facing surface of the first housing;
at least one caster ramp provided on the facing surface of the second housing such that the at least one caster bearing can roll along the at least one caster ramp when the first and second housings are pressed toward each other so that the housings rotate with respect to each other;
and
at least one weight sensor placed on one of the facing surfaces and having a rest position surface adjacent an end of the at least one caster ramp,
wherein the first and second housings stop rotating when the caster bearing reaches and makes contact with the rest position surface, and
wherein the at least one weight sensor is configured to weigh the gas cylinder when the caster bearing rolls off the at least one caster ramp and onto the rest position surface of the at least weight sensor to provide weight data.

A weight scale for a gas cylinder comprising:

a rotatable top housing with a lower surface and an upper surface adapted to receive the gas cylinder;
a stationary bottom housing with an upper surface, which is located opposite the lower surface of the top housing when the weight scale is assembled;
said top housing being capable of being spaced from and rotatable with respect to the bottom housing;
at least one caster bearing rotatably mounted on the lower surface of the top housing;
at least one caster ramp provided on the upper surface of the bottom housing such that the at least one caster bearing can roll down the at least one caster ramp when the top housing is pressed down on the bottom housing so that the top housing rotates with respect to the bottom housing;
and
at least one weight sensor placed on the upper surface of the bottom housing and having a rest position surface adjacent an end of the caster ramp,
wherein the top and bottom housings stop rotating when the caster bearing reaches and makes contact with the rest position surface, and
the at least one weight sensor is configured to weigh the gas cylinder when the caster bearing rolls off the caster ramp and onto the rest position surface to provide weight data.
