First Claim
1. A laboratory balance, comprising:
- a weighing chamber, with a weighing chamber rear wall with at least one passage opening therethrough;
a weighing pan, located inside the weighing chamber;
comprising two sidebars spaced apart and held together by a connecting member, each of the sidebars having a substantially L-shaped configuration with a substantially horizontal portion and a substantially vertical portion that are joined together at a substantially right angle, the vertical portion further comprising a hook-shaped portion;
a housing, adjoining the weighing chamber rear wall; and
a weighing cell, located inside the housing, the weighing cell comprising a load-receiving structure, arranged on a side of the weighing cell that faces the weighing chamber rear wall, the load-receiving structure comprising a suspension pin that extending in a direction transverse of the load-receiving structure), such that the weighing pan moves in a longitudinal direction of the laboratory balance towards and away from the weighing chamber rear wall, the weighing pan being brought into engagement with the load-receiving structure through the at least one passage opening;
wherein the hook-shaped portion is configured to engage the suspension pin and the vertical portion of each sidebars further comprises a guiding portion that extends from the hook-shaped portion towards the load-receiving structure and slopes upwards from the hook-shaped portion, so that, through sliding contact between the suspension pin and the guiding portion, the hook-shaped portion is guided to seated engagement on the suspension pin.

Abstract
A laboratory balance (1) has a weighing pan (14) in a weighing chamber (10). A rear wall (4) separates the weighing chamber separates from a housing (11) that contains a weighing cell (12) with a load-receiving structure (13). A suspension pin (27) extends in a transverse direction of the load-receiving structure. The weighing pan is engaged with the load-receiving structure through at least one passage opening (31) in the rear wall. Two spaced-apart sidebars (29) of the weighing pan are held together by a connecting member (30). Each sidebar has an L-shaped configuration with a horizontal foot portion (55) and a vertical leg portion (56). A hook-shaped portion (64) of the vertical leg is seated on the suspension pin, through sliding contact between the suspension pin and a guiding portion (65) that extends from the hook-shaped portion away from the horizontal foot portion, sloping upwardly.
