Abstract
The support arm (29) for the load-receiving pan (28) of an electronic weighing apparatus (2) is resiliently suspended from the vertically arranged load receiving member (15), thereby to isolate the load receiving member from deleterious forces applied to the weighing pan. To this end, one end of the support arm is suspended by a pair of parallel spaced leaf springs (31,33) from the lower end of the load receiving member. Opposed portions at the upper ends of the leaf springs contain relatively outwardly projecting horizontal U-shaped loop portions (43), thereby to afford resilient displacement of the arm in various directions relative to the load receiving member.
Claims5
Electronic weighing apparatus, comprising:
- (a) a frame (9);
- (b) a vertical load receiving member (15) having an upper end and a lower end;
- (c) parallel guide means (11) connecting said load receiving member for vertical movement relative to said frame;
- (d) a weighing pan (28);
- (e) a horizontal support arm (29) having a pair of ends a first one of which is connected with said weighing pan;
- and
- (f) resilient means for suspending the other end of said support arm from the lower end of said load receiving member, said resilient means including a pair of vertical parallel generally flat leaf springs (31, 33) arranged normal to, and spaced longitudinally of, said horizontal support arm.
