Abstract

The instant invention is concerned with providing safeguards that prevent damage to weighing scale in the case of an overload applied to the side edges of the scale platform. In addition, the invention prevents damage to the weighing mechanism of the scale due to torquing when one attempts to lift the scale by the platform.

Claims

1. A weighing scale comprising:

a) a base,

b) a longitudinally extending platform located above said base and having an opening formed on the lateral underportion thereof,

c) a load call weighing mechanism attaching the platform to the base, and

d) a stop member strut attached to and extending from the base and one end thereof and having a finger at the distal end thereof that is received by said opening in a non contact manner when no load is on said platform.

2. The weighing scale of claim 1 wherein said strut extends from said base at an angle relative to the said base.

3. The weighing mechanism of claim 1 wherein said stop members are rigid.

4. A weighing scale comprising:

a) a base,

b) a horizontally extending platform having openings formed on the underportion thereof located above said base

c) a load cell weighing mechanism attached to the said platform and to said base to provide connection between said platform and said base, and

d) a pair of struts extending generally vertically from said base and being spaced below and relative to said platform, said struts having fingers at the distal ends thereof that are received by said openings in a non contact manner when no load is on said platform.

5. The weighing scale of claim 4 wherein said struts extend from said base at an angle relative to the horizontal.

6. The weighing scale of claim 4 wherein said openings are channels formed by a channel member located along at least one edge of said platform and said struts form generally horizontally extending fingers at their ends thereof and each of said fingers is received within a channel in a spaced relationship whereby upon a load being placed upon said one edge of said platform at least one of said fingers will contact said channel member and upon an upward load being applied to said platform at least one of said fingers will contact said channel member thereby preventing overload to said weighing mechanism.
