Abstract

A portable handheld electronic scale can weigh luggage and other objects. The scale includes an electronic weight-measuring device configured to measure and indicate the weight of the luggage. If the weight of the item of luggage exceeds the weight restriction of an airline, the traveler can reduce the weight of the item of luggage below the weight limit set by the airline by removing some of the contents of the item of luggage. Depending upon the particular embodiment of the scale, a user can comfortably hold the scale either parallel or perpendicular to the ground when the scale is used to lift the item of luggage off of a ground surface in order to obtain the weight of the item of luggage. An audible signal may be given when the measured weight is fixed on a display and/or when it is greater than a set limit.

Claims

1. A portable handheld scale for weighing an object, the scale comprising:

a housing formed with a portion serving as a handle, said housing extending along a longitudinal axis, said handle extending along the longitudinal axis;

an electronic weight-measuring device configured to measure and indicate a weight of the object, said weight-measuring device including a weight sensor for measuring the weight of the object, said weight-measuring device disposed in said housing; and

a support assembly configured to support the object to be weighed, said support assembly attached to said weight sensor, said support assembly including a strap having a first end with a male connector and a second end with a female connector configured to mate with said male connector of said first end of said strap in order to weigh the object;

said weight-measuring device including a display configured to indicate the weight measured by said weight sensor;

said display being disposed in said housing;

said housing having an elongated top side extending along said longitudinal axis and an opposite elongated bottom side extending along said longitudinal axis; and

said display being located in said top side, said bottom side including a central region with an aperture formed therein, and said support assembly extending through said aperture in said bottom side.

2. The scale according to claim 1, wherein said support assembly extends in a direction transverse to said longitudinal axis.

3. The scale according to claim 1, wherein said support assembly is configured to connect to a plurality of different types of attachments for weighing different types of objects.

4. The scale according to claim 1, wherein said weight sensor includes a capacitive load cell configured to measure the weight of the object.

5. The scale according to claim 1, wherein:

said weight-measuring device includes a transducer that provides an audible signal; and

said transducer is configured to provide the audible signal after said weight-measuring device has completed determining the weight of the object and after the weight of the object being shown on the display is fixed.

6. The scale according to claim 1, wherein:

after said weight-measuring device has completed determining the weight of the object and after the weight of the object being shown on the display is fixed, said display provides a visual indication in addition to displaying the weight of the object.

7. The scale according to claim 1, wherein:

said weight-measuring device is configured to operate in a mode in which a weight limit can be set; and

when the weight of the object is greater than the weight limit, said weight-measuring device provides a visual indication in addition to displaying the weight of the object.

8. The scale according to claim 1, wherein said weight-measuring device includes a transducer for providing an audible signal, said weight-measuring device is configured to operate in a mode in which a weight limit can be set, and said transducer provides the audible signal when the weight of the object is greater than the weight limit.

9. A portable handheld scale for weighing an object, the scale comprising:

a housing formed with a portion serving as a handle, said housing extending along a longitudinal axis, said handle extending along the longitudinal axis;

an electronic weight-measuring device configured to measure and indicate a weight of the object, said weight-measuring device including a weight sensor for measuring the weight of the object, said weight-measuring device disposed in said housing; and

a support assembly configured to support the object to be weighed, said support assembly attached to said weight sensor, said support assembly including a strap having a first end with a first connector and a second end with a second connector configured to mate with said first connector of said first end of said strap in order to weigh the object;

said weight-measuring device including a display configured to indicate the weight measured by said weight sensor, said display disposed in said housing, said housing having an elongated top side extending along said longitudinal axis and an opposite elongated bottom side extending along said longitudinal axis, said display located in said top side, said bottom side including a central region with an aperture formed therein, and said support assembly extending through said aperture in said bottom side.

10. The scale according to claim 9, wherein said support assembly extends in a direction transverse to said longitudinal axis.

11. The scale according to claim 9, wherein said support assembly is configured to connect to a plurality of different types of attachments for weighing different types of objects.

12. The scale according to claim 9, wherein said weight sensor includes a capacitive load cell configured to measure the weight of the object.

13. The scale according to claim 9, wherein:

said weight-measuring device includes a transducer that provides an audible signal; and

said transducer is configured to provide the audible signal after said weight-measuring device has completed determining the weight of the object and after the weight of the object being shown on the display is fixed.

14. The scale according to claim 9, wherein:

after said weight-measuring device has completed determining the weight of the object and after the weight of the object being shown on the display is fixed, said display provides a visual indication in addition to displaying the weight of the object.

15. The scale according to claim 9, wherein:

said weight-measuring device is configured to operate in a mode in which a weight limit can be set; and

when the weight of the object is greater than the weight limit, said weight-measuring device provides a visual indication in addition to displaying the weight of the object.

16. The scale according to claim 9, wherein said weight-measuring device includes a transducer for providing an audible signal, said weight-measuring device is configured to operate in a mode in which a weight limit can be set, and said transducer provides the audible signal when the weight of the object is greater than the weight limit.
