Support device for a weighing cell, and balance incorporating the support device
First Claim
1. A support device for a weighing cell, comprising at least one support post connected to and supporting the weighing cell, at least one support spring adapted for connection to a stationary chassis and supporting the at least one support post, and at least one guide member adapted for connection to the stationary chassis;
- whereinthe support post is movable in relation to the stationary chassis in a substantially vertical direction against an opposing force of the at least one support spring;
the at least one support spring is biased with an upward pre-tensioning force against a surface portion of the stationary chassis, and the at least one support post can lift off from a resting place on the at least one support spring but is constrained to a limited range of upward vertical movement by the at least one guide member.

Abstract
A support device for a weighing cell is mounted on one or more support posts resting on support springs that are connected to a stationary chassis and are pre-tensioned with an upward force. In case of a downward-directed shock, the support springs will yield to the inertial shock force and allow the weighing cell to move downward. The support posts can lift off from their resting places on the support springs, but are constrained by guide members to a limited range of upward vertical movement. A balance equipped with the support device has a low profile height and protects the weighing cell from downward- as well as upward-directed shocks.
