## Background
RELATED APPLICATIONS AND PRIORITY
This application is a continuation-in-part of U.S. patent application Ser. No. 12/829,136, filed Jul. 1, 2010, which claims the benefit of U.S. Provisional Application No. 61/299,752, filed Jan. 29, 2010, the entireties of which are hereby incorporated by reference.


FIELD OF THE INVENTION
The present invention relates to a handheld luggage scale, and in particular to a compact, lightweight luggage scale that is easy for a user to hold.
BACKGROUND
Airlines have over time become stricter about luggage size and weight limits, and have introduced high fees for conveying luggage that is over their weight limit. Weight and size limits for luggage can vary from airline to airline, and even by type of flight (for example, international flights typically have a higher weight limit than domestic flights), and a consumer can no longer know in advance whether an item of luggage will meet size and weight restrictions. It has thus become more important to travelers to be able to measure the weight of their luggage before they set out to travel to an airport to check in for a flight. Various consumer-oriented luggage scales have been proposed, but most of the known scales suffer from various drawbacks.
In particular, it is often difficult for people to lift luggage items safely, which luggage scales require them to do. Because they do not necessarily know the proper safe lifting techniques, a person can easily injure their back while lifting luggage, especially if they are not in good physical condition. Most of the known portable electronic scales do not help a person to lift their luggage safely. Also the known scales may have handles which are uncomfortable to hold, may require the person to lift the luggage high up in order to view the weight read-out, and may not allow two-handed operation.
It is therefore desirable to provide novel designs of luggage scales for consumer use, particularly those which are easy to use and which provide ergonomic advantages.

DETAILED DESCRIPTION OF THE INVENTION
The present invention is directed to a handheld electronic luggage scale, and in particular to a compact, lightweight luggage scale that is easy for a user to hold. The term “luggage” as used herein is not meant to be limiting, as the luggage scale can be used for anything that can be hung from a hook. For example, the term “luggage” may cover a suitcase, a briefcase, a laptop bag/case, a computer bag/case, a business case, a travel bag, a beauty case, or a variety of other types of luggage. The scale can also be used with packages, parcels and other items that a user may wish to weigh prior to shipping or posting.
Referring to the drawings, a handheld electronic luggage scale 10 is shown, comprising a handle 20 having a hook attachment 22, a coated luggage hook 30 and an easy-to-read display 40. The handle 20 is designed to be held generally horizontally, with the hook attachment 22 extending generally vertically from the bottom of the handle 20, at a central portion of the handle.
The handle 20 is designed to be small enough to fit snugly within a user's two hands, or a single hand, as they are held in front of the body. In one arrangement, the handle 20 can be approximately 4-5′′ long. The handle can also be picked up with one hand if desired, with the luggage hook attachment 22 passing between the middle fingers. The handle 20 is designed with a slight curve so that ends 24 of the handle 20 on either side of the central hook attachment 22 curve slightly downwardly. The ends 24 can have a greater angle of curvature from horizontal than a central portion of the handle 20. The handle 20 has a suitable length and width so that it fits comfortably in a user's hand or hands.
The handle 20 serves as a housing for internal components and can also include a battery hatch 26. Batteries within the hatch 26 provide power to an electronic scale component (not shown) that is stored within the handle 20. The scale component is also connected to the luggage hook 30 by means of a connector 35 that extends within the hook attachment 22. The luggage hook 30 may be simply hooked through an aperture provided in a free end of the connector 35. As the connector 35 is pulled downwardly, the electronic scale component registers the force acting on the connector 35, and thus the weight of an object that is suspended from the hook 30.
An easy-to-read widescreen digital display 40 is provided on top of the handle 20. The display 40 displays the luggage weight in numbers large enough to be easily viewed by a person holding the handle 20 at about waist height. The display 40 can be an LCD display and it can have blue back lighting for ease of viewing. Of course, any suitable display may be used, and the invention is not limited in this regard. An on/off switch 42 may be provided on the side of the handle 20, and one or more control buttons 44 can be provided on the top of the handle 20. After turning the main on/off switch 42 on, one of the control buttons 44 allows the user to activate the scale 10 to provide a readout of the weight once an item of luggage 50 has been picked up. The electronic scale component reads the weight of the luggage 50 instantly, and can beep as it provides the readout. The display 40 can also change color, for example, to red, when the readout is provided. This provides the user quick notification that the weight reading is completed and that they can set the luggage item 50 back down on the ground. A second control button 44 allows the weight display to be toggled between kilograms and pounds.
The curvature of the handle 20 is designed to provide both comfort and a secure grip to a user, and to assist with safe lifting techniques which should always be practiced to properly lift objects and reduce back strain. This operation is shown in FIG. 3. The user stands close to an item of luggage 50 to be weighed, with their legs shoulder-width apart. The user centers themselves with the electronic scale 10 comfortably resting in their hands. The user connects the hook 30 to a carry handle of the luggage 50. The luggage 50 is then lifted by the user while closely holding the arms to their body, preferably bending their legs while keeping their back straight. As a person raises their arms along their midline, the hands naturally define a greater and greater angle from the horizontal as their elbows splay, and the curvature of the handle 20 of the scale 10 allow for this operation to be carried out comfortably while the user maintains the weight of the luggage 50 evenly across the width of their hands. It has been found that with a straight handle, as the user raises their hands, the weight of the luggage 50 becomes more focused on the ulnar edges of the hands, which can quickly become painful.
Alternatively or additionally, with respect to FIG. 3, the user may operate the handheld electronic luggage scale 10 with one hand. The user may grip the scale 10 with one hand such that the user may be able to view the weight of an object being calculated by the scale 10 and that is being displayed on the display on the top surface of the scale 10. For instance, the display may be viewable between a user's thumb and index finger when gripping the luggage scale 10 with one hand. The one-hand operation may be useful for smaller and/or lighter items as compared to the two-hand operation. The digital display may be sufficiently large to permit viewing of the calculated weight from a distance, such as when the user is hold the luggage scale 10 at arm's length during use or about waist high.
FIG. 4 depicts an exemplary method of using the handheld electronic luggage scale 400. The method 400 may include manufacturing the handheld electronic luggage scale 402, attaching the scale to an object to be weighed 406, adjusting controls and/or settings on the scale 404, lifting the scale and object 408, and viewing the weight of the object being weighed 410. The method may include additional, fewer, or alternate actions.

As shown with respect to FIG. 2, in one embodiment, the luggage hook attachment 22 may be centrally located on the handle 20 and protrude from the bottom of the handle 20. The luggage hook attachment 22 may be generally cylindrical, or tapered and/or funnel shaped with a smooth exterior. The luggage hook attachment 22 may extend from a mid-section of the bottom surface of the handle 20 for approximately 0.25 inches to approximately 2.00 inches. Other sizes may be used. The radius of the luggage hook attachment 22 may be greater in the vicinity of the interconnection of the luggage hook attachment with the bottom of the handle, and smaller in the vicinity of the tip of the luggage hook attachment 22. The tip of the luggage hook attachment 22 may have an a square, round, or other opening leading to a hollow cavity interior of the luggage hook attachment 22.
Further with respect to FIG. 2, the handle may be configured to have a connector 35 that protrudes or extends from the tip or bottom of the luggage hook attachment 22. The connector 35 may be substantially housed within the interior of the luggage hook attachment 22. The connector 35 may have a circular opening at the bottom end configured to accept a luggage hook 30. The opening of the connector 35 may be approximately perpendicular or parallel to the longitudinal length of the handle 20.
As shown in FIG. 2, the luggage hook 30 may have a large, circular hook for hooking luggage and other items, such as by handles on the items to be lifted. The large, circular hook may be coated with a rubber or plastic material. The large, circular hook of the luggage hook 30 may transition to a smaller connector hook. The smaller connector hook may sized to be accepted by the opening of the connector 35 that extends from the luggage hook attachment 22. The transition portion of the luggage hook 30 may having a twisting effect and transition or re-orientate the alignment of the smaller connector hook, which may run approximately parallel to the longitudinal length of the handle 20, by approximately 90 degrees, such that the alignment of the larger, circular hook is approximately perpendicular to the longitudinal length of the handle 20. Other configurations and orientations may be used.
The handle may have a slight curve such that the two longitudinal ends of the handle on either side of the central hook attachment curve slightly downward. The top surface of the handle may curve slightly downward from a central or mid-section to both longitudinal ends of the top surface. The bottom surface of the handle may curve slightly upward and then curve slightly downward from a central or mid-section to both longitudinal ends of the bottom surface, as shown in FIG. 2.
The handheld electronic luggage scale may be manufactured to have a battery hatch located in a top or other surface of the handle. The battery hatch may be located between an electronic display, such as a centrally located or other electronic display on the top surface of the handle, and one longitudinal end of the handle of the scale. The batteries within the hatch may power the electronic scale housed within the handle.
The method of using the handheld electronic luggage scale 400 may include adjusting controls and/or settings on the scale 404. The handle may include an on/off switch for turning the electronic luggage scale on and off. The handle also may include one or more control buttons on the top or other surface of the handle. Two control buttons may be located between the electronic display, such as a centrally located or other electronic display on the top surface of the handle, and the other longitudinal end of the top surface of the handle—the other longitudinal end of the top surface of the handle being opposite the longitudinal end of the top surface of the handle that is closest to the battery hatch.
The user may be able to grab the electronic luggage scale with one hand and operate either of the two control buttons with his or her thumb, similar to remote control operation of a television set. One control button may allow the user to activate the scale and provide a readout of the weight once an item of luggage has been lifted and weighed. The electronic scale component reads the weight of the luggage instantly, and may beep as it provides the readout. The display may be configured to change color or give another indication that a readout is ready for viewing. Another control button may allow the weight display to be toggled between kilograms and pounds, or other units of measurement.
The method of using the handheld electronic luggage scale 400 may include attaching the scale to an object to be weighed 406. The electronic scale component may be interconnected to a luggage hook either directly or indirectly. For example, the luggage hook may be interconnected with a connector or other means that connects the luggage hook to the handheld electronic luggage scale. In one embodiment, the hook supported by the handle may interconnected with the handle via a connector having a vertical alignment that is offset from a vertical alignment of the hook by approximately 90 degrees. The luggage hook may be slid through an aperture on the connector and then hook a handle on a piece of luggage or suitcase, such that the piece of luggage or suitcase is sufficiently attached to the handheld electronic luggage scale.
The hook may be a curved or circular hook. The curved or circular hook may be manufactured of metal, plastic, or other material. The curved hook may include a bottom or large hook portion, and a top or small hook portion. Both the large hook portion and the small hook portion may be configured as curved or circular hooks.
The large hook portion may have a bottom curved hook extending at least approximately 180 degrees radially. In one embodiment, the bottom curved hook may extend approximately 270 degrees radially or have 270 degrees of curvature for hooking or grabbing an object. The bottom curved hook may be configured to be sufficiently strong such that the bottom curved hook may hook a handle or strap on an object, and then be used in conjunction with the handle to lift the object.
The curved hook may include a top or small hook portion having a top curved hook extending from the large hook portion. The vertical alignment of the small hook portion and the vertical alignment of the large hook portion may be approximately 90 degrees offset with respect to each other. The top or small hook portion may have a vertical alignment that is approximately parallel to the longitudinal length of the handle. The bottom or large hook portion may have a vertical alignment that is approximately perpendicular to the longitudinal length of the handle. Other vertical alignments of the top and bottom hook portions may be used.
The method of using the handheld electronic luggage scale 400 may include lifting the scale and object 408. During use, as the user lifts the object using the handle of the luggage scale, the connector may be pulled downward. As a result, the electronic scale component may register the force acting on the connector, and thus the weight of an object that is suspended from the hook may be calculated. The electronic scale may provide an audible and/or visual indication that the weight of the object has been calculated and is being displayed. For instance, the display may change background color or an indicator light may light up to provide a user notification that the weight reading is complete. The indicator light may be located on the surface of the handle between two control buttons and one longitudinal end of the top surface of the handle.
The method of using the handheld electronic luggage scale 400 may include viewing the weight of the object being weighed 410.
