Arrangement for and method of preventing overhanging weighing platter of scale from tipping at product checkout system and method of mounting and removing the weighing platter without tools

摘要

A checkout system includes a workstation having a data capture arrangement for capturing through a horizontal window a target associated with a product to identify the product being checked out at the workstation, and a scale for weighing the product at the workstation. The scale has a scale mechanism, and a weighing platter on which the product is placed for weighing. The weighing platter is integrated with the horizontal window and overlies the scale mechanism. The weighing platter projects past the scale mechanism and has a front end that overhangs the scale mechanism. Non-threaded, interlocking connectors, which are provided on the weighing platter and the scale mechanism, prevent the weighing platter from tipping if a force is exerted on the front end of the weighing platter. The weighing platter is mounted on, and removed from, the scale mechanism without the aid of tools.

1. A checkout system, comprising:
a workstation having a horizontal window located in a generally horizontal plane, and a data capture arrangement for capturing through the horizontal window a target associated with a product to identify the product being checked out at the workstation; and a scale for weighing the product at the workstation, the scale including
a scale mechanism including a frame,a weighing platter on which the product is placed for weighing, the weighing platter being integrated with the horizontal window and overlying the scale mechanism, the weighing platter projecting past the scale mechanism and having a front end that overhangs the scale mechanism, andnon-threaded, interlocking connectors on the weighing platter and the scale mechanism, for preventing the weighing platter from tipping if a force is exerted on the front end of the weighing platter, wherein the non-threaded, interlocking connectors include a pair of spaced-apart hooks depending downwardly from the weighing platter, a pair of spaced-apart slots in the frame, and a pair of spaced-apart catches on the frame for being lockingly engaged by the hooks after the hooks pass through the slots.
