Abstract

The present disclosure relates to a weighing assembly (100) for a luggage case (101). The weighing assembly (100) includes at least one support (107) in contact with a surface that supports a portion of a weight of the luggage case (101). A floating element (108) is coupled to the support (107). A deflection member (110) is coupled to the floating element (108), and the portion of the weight of the luggage case (101) causes an elastic deflection of the deflection member (110). A load cell member (112) disposed adjacent to and separate from the deflection member (110). The load cell member (112) is separate from the deflection member (110) the elastic deflection of the deflection member (110) causes a deflection of the load cell member (112), the load cell member (112) senses the amount of deflection, which correlates to the portion of the weight of the luggage (101).

First claim

What is claimed is:

1. A weighing assembly for a luggage case comprising:
at least one support that carries a portion of a weight of the luggage case when positioned on a support surface;
a deflection member coupled to the support wherein the portion of the weight of the luggage case causes a deflection of the deflection member; and
a load cell member disposed adjacent to and separate from the deflection member, wherein:
the load cell member is separate from the deflection member,
the elastic deflection of the deflection member causes a deflection of the load cell member,
the load cell member senses the amount of deflection, and
the sensed deflection of the load cell member correlates to the portion of the weight of the luggage.

2. The weighing assembly of claim 1 , further comprising a floating element disposed between the deflection member and the support to couple the support to the deflection member.

3. The weighing assembly of claim 1 , wherein the deflection member is cantilevered from a support housing.

4. The weighing assembly of claim 3 , wherein the support housing is adapted to couple to a luggage article, and wherein one portion of the deflection member is secured to the support housing, and another portion of the deflection member is secured to the floating member.

5. The weighing assembly of claim 4 , wherein:
the deflection member defines an elongated body member,
the one portion is a first end portion, and
the another portion is an opposing end portion.

6. The weighing assembly of claim 1 , wherein the load cell member includes a strain sensor that correlates a strain of the load cell member to the deflection of the load cell.

7. The weighing assembly of claim 6 , wherein at least one of the deflection of the load cell member or the deflection of the deflection member is correlated to at least a portion of the weight of the luggage case.

8. The weighing assembly of claim 6 , wherein the deflection of the load cell member and the deflection of the deflection member are together correlated to at least a portion of the weight of the luggage case.

9. The weighing assembly of claim 6 , wherein the load cell member includes three strain sensors that together correlate a respective strain of each of the three strain sensors to the deflection of the load cell member.

10. The weighing assembly of claim 1 , wherein the deflection member comprises a prismatic beam.

11. The weighing assembly of claim 10 , wherein the deflection member further comprises a transverse aperture that modifies an elastic characteristic of the deflection member.

12. The weighing assembly of claim 1 , wherein the support is one of a spinner wheel, a foot, or a post.

13. A luggage case including the weighing assembly of claim 1 , wherein the weighing assembly determines the weight of the luggage case.

14. The luggage case of claim 13 , including a plurality of the weighing assemblies of claim 1 .

15. The luggage case of claim 14 , including four of the weighing assemblies of claim 1 .

16. The luggage case of claim 14 , further including a processing element that:
communicates with each of the plurality of weighing assemblies;
determines a weight associated with each of the plurality of weighing assemblies;
combines the weight associated with each of the plurality of weighing assemblies to determine a total weight of the luggage case; and
displays the total weight of the luggage case.

17. The luggage case of claim 16 , including a display to display the total weight of the luggage case.

18. The luggage case of claim 15 , wherein the weighing assembly is activated by an actuator.

19. The luggage case of claim 1 , wherein a lower surface of load cell member slips with respect to an upper surface of deflection member.

20. A weighing assembly for a luggage case comprising:
at least one support that carries a portion of a weight of the luggage case when positioned on a support surface;
a substantially prismatic deflection member coupled to the support wherein the portion of the weight of the luggage case causes a deflection of the deflection member; and
a load cell member affixed to the deflection member, wherein:
the elastic deflection of the deflection member causes a deflection of the load cell member,
the load cell member senses the amount of deflection, and
the sensed deflection of the load cell member correlates to the portion of the weight of the luggage.
