Pull handle of luggage

A pull handle of a luggage, which is adapted for accommodating a control device having a button, includes a main body and a cover. The main body has a transverse pipe, two vertical pipes integrally extended from two ends of the transverse pipe respectively, and a hollow portion located at the transverse pipe. The cover is mounted to the main body and covers at least one part of the hollow portion. The cover and the transverse pipe constitute a grip which has an opening corresponding in position to the button of the control device. In this way, the pull handle is not only firm in structure so as to be uneasily damaged and have long life time, but also simplified in assembling process.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to pull handles and more particularly, to a pull handle of a luggage.

2. Description of the Related Art

A conventional pull handle of a luggage primarily includes a grip, and two straight rods installed at two ends of the grip, respectively. A button is located on the pull handle to enable the pull handle to be stuck out or retracted into the case of the luggage by the user according to the usage requirements. However, after the luggage is used for a long time, the grip is liable to be separated from the two straight rods because the grip and the straight rods are not connected firm enough. For example, if the luggage is carelessly transported in the airport or knocks against other luggage in the shipping process, or the weight of the case of the luggage exceeds the highest weight the pull handle can bear, the pull handle is liable to be separated or damaged.

SUMMARY OF THE INVENTION

The present invention has been accomplished in view of the above-noted circumstances. It is an objective of the present invention to provide a pull handle of a luggage, which is firm in structure so as to be uneasily damaged, and simplified in the assembling process.

To attain the above objective, the present invention provides a pull handle of a luggage, which is adapted for accommodating a control device having a button. The pull handle includes a main body and a cover. The main body has a transverse pipe, two vertical pipes integrally extended from two ends of the transverse pipe respectively, and a hollow portion located at the transverse pipe. The cover is mounted to the main body and covers at least one part of the hollow portion. The cover and the transverse pipe constitute a grip which has an opening corresponding in position to the button of the control device.

The main body of the pull handle is made integrally, so it doesn't need to be assembled, thereby easy in manufacturing. Besides, the pull handle is firm in structure so as to be uneasily damaged and extend the life time of the luggage.

DETAILED DESCRIPTION OF THE INVENTION

Referring toFIGS. 1-3, a pull handle1of a luggage according to a first embodiment of the present invention is adapted for accommodating a control device2. The control device2has a button3, a base4attached to the bottom of the button3, two connecting rods5extended downwardly from two ends of the base4, and a compressive spring6disposed under the base4. The pull handle1includes a main body10and a cover20.

The main body10has a transverse pipe11, two vertical pipes13integrally extended downwardly from two ends of the transverse pipe11respectively, and a hollow portion15located at the downside of the transverse pipe11and extended to the inner sides of the two vertical pipes13. The main body10may, but not limited to, be made of aluminum, aluminum alloy, or stainless steel. The transverse pipe11is adapted for accommodating the base4and the compressive spring6of the control device2, and the two vertical pipes13are adapted for accommodating the two connecting rods5. The bottom ends of the two vertical pipes13may be inserted into two sleeves (not shown) to constitute telescopic rods capable of being lengthened and shortened. The bottom ends of the two connecting rods5are connected with a lock mechanism (not shown), so that the user can control the lock mechanism to lock or release the telescopic rods by pressing the button3. When the telescopic rods are locked, the two vertical pipes13are immovable relative to the two sleeves, so that the telescopic rods can't be lengthened or shortened. When the telescopic rods are released, the two vertical pipes13are movable relative to the two sleeves, so that the telescopic rods can be lengthened or shortened.

The cover20is mounted to the main body10and covers at least one part of the hollow portion15, so that the cover20and the transverse pipe11of the main body10constitute a grip30. The grip30has an opening31corresponding in position to the button3of the control device2. In this embodiment, the hollow portion15is completely covered by the cover20, the opening31is located at the upside of the transverse pipe11of the main body10, and the button3is protruded out of the opening31. The compressive spring6is disposed between the cover20and the base4to provide an upward force, so that the button3is protruded out of the opening31when receiving no external force.

The main body10and the cover20can be combined together by some fastening elements such as screws or bolts, or by other connecting ways. Because the main body10of the pull handle1is made integrally, it doesn't need to be assembled so as to simplify the assembling process of the pull handle. Besides, the pull handle1is firm in structure so as to be more uneasily damaged than the conventional pull handles, thereby extending the life time of the luggage. In the process of manufacturing the main body10, a straight pipe is made by aluminum extrusion, partially removed to form the hollow portion15, and then bended to become the main body10. The hollow portion15makes the straight pipe more easily bended to become the main body10, and the control device2can be installed into the main body10through the hollow portion15.

In other embodiments, the hollow portion15may be only located at the transverse pipe11of the main body10without extending to the two vertical pipes13. Alternately, the hollow portion15may be located at other positions of the main body10. For example, in the pull handle1′ according to a second embodiment as shown inFIG. 4, the hollow portion15is located at the upside of the transverse pipe11, and may be further extended to the outer sides of the two vertical pipes13. The cover20is mounted to the main body10and covers the hollow portion15, and the opening31is located at the cover20. Another example is a pull handle1″ according to a third embodiment as shown inFIG. 5, wherein the cover20is composed of two cover pieces20′. The opening31is a part of the hollow portion15of the main body10, which is not covered by the cover20. This means the opening31is the uncovered part of the hollow portion15located at the juncture of the two cover pieces20′. The button3of the control device2is protruded out of the opening31. However, the button3may be configured to be not protruded out of the opening31, depending on the usage requirements.

In conclusion, based on the spirit of the present invention, the hollow portion may be located at the upside, downside or other positions of the transverse pipe of the main body, and completely or partially covered by the cover; the opening may be located at the transverse pipe or the cover. Because the transverse pipe and the two vertical pipes are made integrally, the pull handle of the present invention has great structural strength and long life time. The above description represents merely the preferred embodiments of the present invention, without any intention to limit the scope of the present invention. The simple variations and modifications not to be regarded as a departure from the spirit of the invention are intended to be included within the scope of the following claims.
