AI Technical Summary

Benefits of technology

The scale provides comfortable and efficient weight determination with improved balance and visibility, allowing users to easily measure and manage luggage weights, and adjust for tare weights, while being easily stowed for convenience.

Problems solved by technology

The ever-increasing cost of fuel has caused the travel industry, and in particular the air travel industry, to assess a surcharge for luggage whose weight exceeds a predetermined maximum.
However, the scales currently available have a number of drawbacks, chief among which are the lack of a weight display viewable from directly above the scale, having only a single handle with which to lift when weighing and lack of stowability of the scale's luggage hook.

Abstract

A portable digital scale is disclosed, having retractable and stowable handles and weighing hook, as well as a weight display that may be viewed from directly above the scale.

Description

BACKGROUND OF THE INVENTION[0001]The ever-increasing cost of fuel has caused the travel industry, and in particular the air travel industry, to assess a surcharge for luggage whose weight exceeds a predetermined maximum. This development has spawned the invention of a fair number of portable luggage scales, the aim of which is to allow the traveler to avoid such surcharges by personally checking luggage weight prior to departure. However, the scales currently available have a number of drawbacks, chief among which are the lack of a weight display viewable from directly above the scale, having only a single handle with which to lift when weighing and lack of stowability of the scale's luggage hook.[0002]These drawbacks are overcome by the present invention, which is summarized and described in detail herein.BRIEF SUMMARY OF THE INVENTION[0003]According to the present invention there is provided a portable scale having two retractable and stowable handles, a retractable weighing hook ...
