An integral weighing device for determining whether the weight of a luggage container and its contents exceed a maximum allowable amount simply by suspending the container by its handle. If the container weighs more than a set amount the integral weighing device provides a visual cue that the container exceeds the predefined weight. The integral weighing device comprises a torsion spring mounted within a housing, and a cord attached to each end of the torsion spring and fed via a guide-way through and out of the housing to an externally accessible grip handle. An indicator arm is rotationally mounted to the housing. When a person lifts the luggage by the grip handle the force is transferred to the torsion spring causing angular deflection toward the indicator arm. If the container exceeds the set weight the indicator arm provides a visual cue that the bag exceeds the predetermined weight.

1. In combination with a luggage container defining a volume for holding contents, a weight-indicating device for indicating when the weight of said luggage container and its contents exceeds a predetermined weight, said weight-indicating device further comprising: a housing affixed to said luggage container, said housing defining an interior space therein and further comprising a post extending into said space;a torsion spring comprising a coil seated on said post and at least one leg extending from said coil;at least one cord affixed at a first end to said at least one leg of said the torsion spring;a handle assembly comprising a base affixed to an external surface of said luggage container, and a handle movable relative to said base, a second end of said at least one cord being affixed to said handle; andan indicator mounted in said housing within a deflection path of the at least one torsion spring leg and movable from a first position when said predetermined weight is exceeded to a second position wherein said indicator is visible externally to said luggage container. 2. The weight-indicating device of claim 1, wherein said at least one leg of said torsion spring is deflected by tensile force developed in said cord by gravity when said luggage container is suspended by said handle. 3. The weight-indicating device of claim 1, wherein said indicator arm is pivotally mounted to said housing and further comprises a tab disposed within said interior space in a deflection path of said at least one torsion spring leg, and an indicator, said indicator arm being rotatable from a first position when said predetermined weight is exceeded to a second position wherein said indicator is visible externally to said luggage container. 4. The weight-indicating device of claim 3, wherein deflection of said at least one torsion spring leg causes said leg to engage said tab and pivots said indicator arm into said second position when said tensile force meets or exceeds said predetermined weight for said luggage container and its contents. 5. The weight-indicating device of claim 1 further comprising a biasing spring engaged to said housing and acting on said indicator arm to bias said arm to said first position. 6. The weight-indicating device of claim 1 further comprising a tensioning spring engaged to said housing, said tensioning spring being slideably engaged to said cord so as to maintain said cord in tension when said device is not in use. 7. The weight-indicating device of claim 1 wherein said least one leg extending from said coil comprises two legs and said at least one cord comprises two cords, a first end of the second cord attached to the second leg and extending there from to a second end affixed to said handle, whereby both of said torsion spring legs are deflected by the tensile force developed in said cords when said luggage container is suspended by gravity from said handle. 8. The weight-indicating device of claim 7 wherein said second leg has a spring constant greater than a spring constant of the first said leg, said luggage container further comprising a second indicator arm pivotally mounted to said housing; said second indicator arm comprising a second tab disposed within said interior space in a deflection path of said second leg and a second indicator, said second indicator arm rotatable from a first position when a second predetermined weight is exceeded to a second position wherein said second indicator is visible externally to said luggage container. 9. The weight-indicating device of claim 7 wherein said second cord engages said second leg at appoint closer to said post than the point at which said first cord engages said first leg, said luggage container further comprising a second indicator arm pivotally mounted to said housing; said second indicator arm comprising a second tab disposed within said interior space in a deflection path of said second leg and a second indicator, said second indicator arm rotatable from a first position when a second predetermined weight is exceeded to a second position wherein said second indicator is visible externally to said luggage container. 10. The weight-indicating device of claim 1 wherein said indicator is further rotatable from said second position when a second predetermined weight greater than the first predetermined weight is exceeded to a third position whereby a second indicator is visible externally to said luggage container. 11. The weight-indicating device of claim 1 wherein said housing is affixed to said luggage container within said volume, and wherein said base further comprises a viewing aperture, said indicator visible within said viewing aperture when said leg engages said tab. 12. A device to determine whether the weight of a luggage container and its contents exceeds a predetermined weight, comprising: a housing affixed to said luggage container, said housing defining an interior space therein and further comprising a post extending into said space;a torsion spring, said torsion spring mounted on said post and having at least one leg extending there from;at least one cord affixed at a first end to said at least one leg of said the torsion spring;a handle assembly affixed to an external surface of said luggage container, said handle assembly comprising a base and a handle, said handle operatively engaged with said base and affixed to a second end of said at least one cord; andan indicator arm pivotally mounted to said housing;said indicator arm comprising a tab disposed within said interior space in a deflection path of said leg and an indicator, said indicator arm rotatable from a first position when said predetermined weight is exceeded to a second position wherein said indicator is visible externally to said luggage container;whereby said at least one leg of said torsion spring is deflected by the tensile force developed in said cord by gravity when said luggage container is suspended by said handle, and whereby said deflection is sufficient for said leg to engage said tab and thereby cause said arm to pivot into said second position when said tensile force meets or exceeds said predetermined weight for said luggage container and its contents. 13. The luggage container of claim 12 further comprising a biasing spring engaged to said housing and acting on said indicator arm to bias said arm to said first position. 14. The luggage container of claim 12 further comprising a tensioning spring engaged to said housing, said tensioning spring slideably engaged to said cord so as to maintain said cord in tension when said device is not in use. 15. The luggage container of claim 12 wherein said least one leg extending from said coil comprises two legs and said at least one cord comprises two cords, a first end of the second cord attached to the second leg and extending there from to a second end affixed to said handle, whereby both of said legs of said torsion spring are deflected by the tensile force developed in said cords by gravity when said luggage container is suspended by said handle. 16. The luggage container of claim 15 wherein said second leg has a spring constant greater than a spring constant of the first said leg, said luggage container further comprising a second indicator arm pivotally mounted to said housing; said second indicator arm comprising a second tab disposed within said interior space in a deflection path of said second leg and a second indicator, said second indicator arm rotatable from a first position when a second predetermined weight is exceeded to a second position wherein said second indicator is visible externally to said luggage container. 17.
