2. Description of Related Arts
Traveling containers are considered as one of the useful tools for traveling. A conventional container such as a fabric type carrying baggage or a metal type carrying case has several drawbacks. One of the problem with the conventional carrying container is that they are bulky, usually heavy, and difficult to carry. In other words, the carrying container is immobilized at all times such that the user usually picks up the carrying container when he or she has to move from place to place. Therefore, such carrying container usually incorporates with a retractable handle bar assembly such that the user is able to easily carry the carrying container by slidably extending a hand bar of the retractable handle bar assembly.
In addition, when the user waits for the check in at the airport, he or she will usually put the carrying container aside until the departure time comes, so that the carrying container will be stolen easily. In other words, there is no alert system incorporated with the conventional carrying container to prevent the carrying container from being unintentionally stolen.
Moreover, all the conventional carrying containers are looked similar, the user may merely pick up a wrong carrying container that is not belong to him or her. Therefore, there are thousands of carrying containers lost at the airport everyday while the carrying containers are either taken by fault or stolen.

The locking means 30 of the retractable handle bar assembly has an operation slot 31 formed on the first supporting wall 11 to communicate the receiving cavity 13 with outside and comprises a locking member 32 movably supported within the receiving cavity 13 and an operation button 33 extended from the locking member 32 to outside through the operation slot 31 for operating the locking member 32 to move from a normal locking position to an unlocking position.
The locking member 32 further comprises an arm locker 321 extended from the hand bar 10 to the retractable base 21 through the retractable arm 22 wherein at the locking position, the arm locker 321 normally locks up the retractable arm 22 with the retractable base 21 and at the unlocking position, the operation button 33 is pressed to drive the locking member 32 to release the locking up of the retractable arm 22 with respect to the retractable base 21 through the arm locker 321.
Accordingly, the locking means 30 further comprises a sliding guider 34 supported within the receiving cavity 13 at a position between the first supporting wall 11 and the second supporting wall 12 for guiding the locking member 32 to slide within the receiving cavity 13 so as to guide the locking member 32 moving from the locking position to the unlocking position. The sliding guider 34 comprises a guiding rail 341 extended from the first supporting wall 11 to the second supporting wall 12 through a through hole 320 formed on the locking member 32 such that when a pressing force is applied on the operation button 33, the locking member 32 is driven towards the second supporting wall 12 to release the locking up of the retractable arm 22 with respect to the retractable base 21.
According to the preferred embodiment, the safety alert system 40 further comprises an electric circuit 42 which is supported by the locking member 32 within the receiving cavity 13 and is electrically connect with the alert signal generator 41, and a control switch 43 connected to the electric circuit 42 and arranged in such a manner that when the locking member 32 is actuated to automatically actuate the control switch 43, the alert signal generator 41 is activated to produce the alert signals.
Accordingly, the electric circuit 42 is configured that the alert signal generator 41 is preset to produce the alert signals for a predetermined time period. Alternatively, the control switch 43 is actuated to activate the alert signal generator 41 for producing the alert signals and to deactivate the alert signal generator to stop producing the alert signals in a sequence manner.
FIG. 3 illustrates an electric diagram of the electric circuit 42 wherein the electric circuit 42 comprises an IC board 421 supported by the locking member 442 and a power source 422 electrically mounted on the IC board 421. According to the preferred embodiment, the power source 422 is a replaceable battery mounted on the IC board 421 for providing electricity.
As shown in FIG. 2, the control switch 43 is a depressible button electrically mounted on the electric circuit 42 at a position towards the second supporting wall 12 in such a manner that when the operation button 33 is pressed towards the receiving cavity 13, the control switch 43 is pressed by the second supporting wall 12 so as to activate the alert signal generator 41. In other words, the first and second supporting walls 11, 12 of the hand bar 10 has a predetermined distance that when the user presses the locking member 32 on the first supporting wall 11 to release the locking up of the retractable arm 21, the control switch 43 is pressed on the second supporting wall 12 to activate the alert signal generator 41. Therefore, when the retractable handle bar assembly is actuated to move the container body 2 of the traveling container 1, the safety alert system 40 provides added alert signals to the traveling container 1, so as to aid the user in notifying the traveling container 1 in attendance.
Accordingly, the alert signal generator 41 comprises at least an illuminator 411 electrically mounted on the IC board 421 of the electric circuit 42 wherein the illuminator 411 is arranged to be activated to produce visible signals as the alert signals. The illuminator 411, according to the preferred embodiment, is a LED capable of generating the visible signals as the alert signals to enhance the visibility of the container body 2 so as to increase the safety purpose of the traveling container 1.
As shown in FIG. 2, the alert signal generator 41 further comprises a panic generator 412 electrically mounted on the IC board 421 of the electric circuit 42 wherein the panic generator 412 is arranged to be activated to produce panic signals as the alert signals. In other words, the alert signal generator 41 produces not only visible signals but also panic signals as the alert signals to enhance the safety of the traveling container 1.
FIG. 4 illustrates an alternative mode of the safety alert system 40′ which is detachably mounted to the hand bar 10′ of the retractable handle bar assembly. As shown in FIG. 4, the first casing 101′ of the hand bar 10′ is mounted to the folding means 20′ wherein the locking means 30′ is received in the first casing 101′ of the hand bar 10′ to form as a conventional retractable handle bar assembly.
The second casing 102′ of the hand bar 10′, having a U-shaped cross sectional, detachably mount on the first casing 101′ in a slidably movable manner to form the receiving cavity 13′ within the first and second casings 101′, 102′, wherein the safety alert system 40′ is received in the first casing 101′. Accordingly, the control switch 43′ of the safety alert system 40′ is a depressible button electrically mounted on the electric circuit 42′ at a position towards the first casing 101′ in such a manner that when the second casing 102′ is pressed towards the first casing 101′, the control switch 43′ is pressed by the first casing 101′ so as to activate the alert signal generator 41′. In other words, since the user must apply a gripping force on the hand bar 10′, the gripping force will force the second casing 102′ to press towards the first casing 101′ to actuate the control switch 43′ so as to activate the alert signal generator 41′ for producing the alert signals for the traveling container.
One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
