Abstract:
A weigh module (1) includes a load cell (2), a base plate (3), a top plate (6), a force-transmitting member (8) serving to transmit the weighing force from the top plate (6) to the load cell (2), and movement-restricting means (9, 10) which serve to limit the horizontal floating movement of the top plate (6) relative to the base plate (3) within a confined range of free play and to transmit lateral force components directly from the top plate (6) to the base plate (3). One part of the movement-restricting means (9, 10) has the form of a channel whose top edges (11) are rigidly connected to the top plate (6) and whose flat bottom extends parallel to the base plate (3) at a clear distance from the latter. The other part of the movement-restricting means (9, 10) is a bolt whose shaft (15) is anchored in the base plate (3) and passes with all-around clearance through a passage (14) in the channel bottom (13), and whose head (16) is larger than the passage (14) and arranged above the channel bottom (13) with a vertical clearance gap from the latter.
