ABSTRACT:
A shock protection device for a force measuring apparatus, particularly a balance, which includes a material block with a stationary parallelogram side member, a deflectable parallelogram side member serving for receiving the force to be measured, two guide members which are bending-elastic in the plane of the parallelogram and which connect the two parallelogram side members, and at least one lever which is connected through a coupling member to the deflectable parallelogram side member. The shock protection device includes a safety bolt inserted into a bore extending at least partially through the force measuring apparatus, wherein the safety bolt is connected without play to one of the components forming the force measuring apparatus, while the safety bolt has radial play relative to the remaining components through which the bolt extends.
