Abstract
The luggage device has an extendible handle threaded in at least a tubular sleeve. An elastic element is housed in the tubular sleeve, supporting from below a connecting rod. A bottom end of the connecting rod is configured with a brake pad. A blind hole is configured on the extendible handle where a spring and a steel ball are housed to interact with a through hole of the tubular sleeve. When the extendible handle is pushed downward, the blind hole is aligned with the through hole of the tubular sleeve and the steel ball is pushed by the spring into the through hole, thereby detachably locking the extendible handle. In the mean time, the connecting rod is driven downward and the brake pad is pressed against the wheel to prevent it from rolling.
Description
- The present invention generally relates to wheeled luggage, and more particularly to a wheeled luggage device having a brake mechanism engaged and disengaged by the luggage device's extendible handle.
- Wheeled luggage provides a traveler with supreme comfort, as the individual no longer has to carry the luggage, which can place significant pressure on the arm, shoulder and back. Despite its convenience, wheeled luggage would unexpectedly slide when it is placed on a tilted ground or in a moving vehicle, or when it is pushed.
- To prevent the unexpected slide, there are various types of wheeled luggage that have a braking mechanism on the wheels, or have the wheels folded and fixed. For the latter, folding the wheels usually requires a user's stamping or squatting to operate. It is not only inconvenient and, when the luggage suddenly moves, hardly a user could respond in time to fold and fix the wheels.
- Therefore a novel luggage device is provided herein, which contains an extendible handle, at least a tubular sleeve, at least a connecting rod, wheels, and a casing. Wheels are configured on a bottom side of the casing. The tubular sleeve is configured vertically along a back side of the casing. An elastic element is housed in the tubular sleeve, supporting from below a lower piston and the connecting rod. A bottom end of the connecting rod is configured with a brake pad. A leg of the extendible handle is threaded in the tubular sleeve and a bottom end of the leg is configured with an upper piston. A blind hole is configured on a leg of the extendible handle where a spring and a steel ball are housed. When the extendible handle is retracted, the blind hole is aligned with a through hole of the tubular sleeve and the steel ball is pushed by the spring into the through hole, thereby detachably locking the extendible handle.
- To prevent the wheeled luggage from sliding, the extendible handle is pushed downward and the upper piston drives the lower piston and the connecting rod downward and compresses the elastic element. The brake pad is descended by the connecting rod and pressed directly against a wheel. When the extendible handle is pulled upward, the steel ball is forced out of the through hole. As the extendible handle is pulled upward, the elastic element raises the lower piston and the connecting rod. The brake pad is thereby lifted to allow the wheel to roll freely.
- The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
- Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
-
FIG. 1 is a perspective diagram showing a wheeled luggage and a partial interior of the wheeled luggage according to an embodiment of the present invention. -
FIG. 2 is a perspective diagram showing the wheeled luggage ofFIG. 1 when the extendible handle is pulled upward with enlarged views of a handle locking mechanism and a wheel braking mechanism. -
FIG. 3 is a perspective diagram showing the wheeled luggage ofFIG. 2 when the extendible handle is retracted. -
FIG. 4 is a schematic diagram showing the inside of the wheeled luggage ofFIG. 1 when the extendible handle is pulled upward with enlarged views of a handle locking mechanism and a wheel braking mechanism. -
FIG. 5 is a schematic diagram showing the wheeled luggage ofFIG. 4 when the extendible handle is retracted. - The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
- As illustrated in
FIG. 1 , a wheeled luggage device according to an embodiment of the present invention contains anextendible handle 1, at least atubular sleeve 2, at least a connectingrod 3,wheels 4, and acasing 5. - As further shown in
FIGS. 2 to 5 , at least twowheels 4 are configured on a bottom side of thecasing 5. Thetubular sleeve 2 is configured vertically inside and along a back side of thecasing 5. Anelastic element 23 is housed in a lower section of thetubular sleeve 2, supporting from below alower piston 22 and the connectingrod 3. A bottom end of the connectingrod 3 is configured with abrake pad 32 and the connectingrod 3 has anadjustment screw 31 inside thecasing 5 adjacent to thebrake pad 32. A leg of theextendible handle 1 is threaded in thetubular sleeve 2 and a bottom end of the leg is configured with anupper piston 21 inside thetubular sleeve 2. - To prevent the wheeled luggage from sliding, the
extendible handle 1 is pushed downward so that it is retracted into thetubular sleeve 2. Inside thetubular sleeve 2, theupper piston 21 drives thelower piston 22 and the connectingrod 3 downward and compresses theelastic element 23. Thebrake pad 32 is as such descended by the connectingrod 3 and pressed directly against awheel 4 to prevent thewheel 4 from rolling. Ablind hole 11 is configured near the bottom end of a leg of theextendible handle 1, and aspring 112 and asteel ball 113 are housed in theblind hole 11. When theextendible handle 1 is retracted as described above, theblind hole 11 is aligned with athrough hole 20 of thetubular sleeve 2 and thesteel ball 113 is pushed by thespring 112 into the throughhole 20, thereby detachably locking theextendible handle 1 in this retracted position. When theextendible handle 1 is pulled upward, thesteel ball 113 is forced out of the throughhole 20 and the inner side wall of thetubular sleeve 2 pushes thesteel ball 113 inward to compress thespring 112. Theextendible handle 1 therefore escapes out of the retracted position. As theextendible handle 1 is pulled upward, theelastic element 23 raises thelower piston 22 and the connectingrod 3. Thebrake pad 32 is thereby lifted to allow thewheel 4 to roll freely. - While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
