The invention generally relates to a locking mechanism for locking a handle of a rollable suitcase.
Traditionally, rollable suitcases have extendable handles that extend and contract from the suitcase. The handle is useful for pulling luggage around airports, train stations, etc. Rollable suitcases have gained popularity as travelers no longer need to lift and carry potentially heavy suitcases long distances. As these types of suitcases grow in popularity, there is an increasing chance that travelers will mistake their own bag from a similar looking bag. Additionally, because there may be times when travelers are away from their suitcases, (e.g., suitcases arrive at a baggage claim area of an airport terminal before the traveler deplanes and arrives at the terminal to pick up suitcases, missed connecting flights, etc.) it is relatively for a thief to simply pick up a stranded suitcase and roll the suitcase away.

Described herein is a suitcase having a locking mechanism disposed on the handle of the suitcase according to embodiments. The suitcase has a plurality of wheels disposed on a distal end. A casing is at least partially disposed on a first side of the suitcase. At least one extendable arm is slideably coupled to the casing and the arm is configured to move between a retracted position and an extended position. A handle is coupled to the at least one arm and a button is disposed on the handle. When the button is depressed, the handle can be moved from the retracted position to an extended position. A locking mechanism is also disposed on the handle which prohibits the button from being depressed when the locking mechanism is in a locked state.
In another embodiment, a rollable suitcase is disclosed having a set of wheels disposed on a bottom portion of the suitcase. An extendable handle is coupled to at least one arm and is configured to move from a retracted position to an extended position. A locking mechanism is disposed on the handle. The locking mechanism is configured to prohibit the extendable handle from moving from a retracted position to an extended position when the locking mechanism is in a locked state.
In still yet other embodiments, a method for locking an extendable handle of a rollable suitcase is disclosed. According to embodiments, the extendable handle of the rollable suitcase is moved from an extended position to a retracted position. A locking mechanism, disposed on the handle of the rollable suitcase, may be locked. The locking action prohibits the extendable handle from moving from the retracted position to the extended position.
Identification of personal luggage and suitcases at airports, train stations and other such transportation mediums can be difficult because many suitcases may look or be similar. Having a locking mechanism disposed on the handle, or alternatively near the handle, may be useful in identifying personal luggage. For example, if a traveler mistakes a similar looking bag for his/her own and is unable to extend an extendable handle due to a locking mechanism, the traveler instantly knows he/she grabbed the wrong suitcase. Additionally, a locking mechanism, such as the one described herein, may deter thieves from taking baggage that has been placed or left in a baggage claim area of an airport as the thief would potentially have to carry the suitcase instead of roll it.
The extendable handle 110 has a button 120 which, when depressed, enables the arms 140 of the suitcase 160 to move from the retracted position to an extended position and vice versa. The extendable handle 110 also has a locking mechanism 130 disposed thereon. The locking mechanism 130 can be changed from a locked state to an unlocked state and vice versa. When in the locked state, the locking mechanism 130 prohibits the button 120 from being depressed, which in turn, prohibits the extendable handle 110 and arms 140 from being moved from a retracted position to an extended position.
Although
According to embodiments, the locking mechanism 130 may be a combination lock, such as shown in
It is also contemplated that the locking mechanism and button may be used to lock the extendable handle in an extended position. In such an embodiment, when the extendable handle is in an extended position, the locking mechanism may be set to a locked state. When in the locked state, the locking mechanism prevents the button from being depressed, which in turn may prevent the extendable handle from moving from an extended position to a retracted position.
Other embodiments provide that the locking mechanism is a bolt and key lock. Although specific embodiments are described, it is contemplated that any form of locking mechanism that would prohibit or enable a button, such as for example button 120, being depressed may be used.
The suitcase 160 also includes casing 150 disposed on a top portion of the suitcase 160. When the extendable handle 110 is in a contracted position, as shown by
According to embodiments, the extendable handle 110 has a button 120 disposed thereon. The button 120 may be located on top of the handle, at the bottom of the handle or on a side of the handle. The button 120 controls the extension and retraction of the extendable handle 110. For example, when the button 120 is depressed, an upward force may be exerted on the extendable handle 110. As a result of the combination of the button being depressed and the upward force, the extendable handle 110 moves in the upward direction from a retracted position to an extended position.
Although specific examples discussed herein disclose a button that is depressed, it is contemplated that any type of button, switch, or knob may be used along with a locking mechanism to control the extension and retraction of an extendable handle of a suitcase.
Embodiments provide that the locking mechanism 130 is placed directly on a button 120. Other embodiments provide that the locking mechanism 130 is disposed on the handle near the button. Still yet other embodiments provide that a locking mechanism 130 may be disposed on the casing 150 and lock the arms 140 in a retracted position. As previously discussed, the locking mechanism may be a combination type lock having a plurality of dials 135 that are used to input various number and/or letter combinations into the locking mechanism 130. When the correct combination is shown on the plurality of dials 135, the button may be depressed and the extendable handle 110 may be extended.
In alternative embodiments, a locking mechanism, such as locking mechanism 310 may be placed near the set of wheels 210 (or a single wheel of the set of wheels) positioned at a bottom portion of the suitcase 160. When the locking mechanism 310 is in the locked position, the bolt 320 moves from a retracted position to an extended position and locks the wheels.
According to embodiments, a wheel locking control mechanism 510 controls whether the wheel locking mechanism 520 is engaged or disengaged. According to embodiments, the wheel locking control mechanism may be coupled to arms 140 of the suitcase 160. As the arms 140 move from a retracted position to an extended position, the wheel locking control mechanism 510 disengages the wheel locking mechanism 520. As arm 140 is moved from the extended position to the retracted position, the wheel locking control mechanism 510 engages the wheel locking mechanism 520.
Alternatively, the wheel locking control mechanism 510 may be coupled to the extendable handle 110. In such embodiments, when the extendable handle 110 moves from a retracted position to an extended position, the wheel locking control mechanism 510 disengages the wheel locking mechanism 520 and the wheels are able to roll. As the extendable handle 110 is moved from the extended position to the retracted position, the wheel locking control mechanism 510 engages the wheel locking mechanism 520 and the wheels are locked once again.
In still yet other embodiments, the wheel locking control mechanism 510 may be placed inside a housing in which the arms 140 are slideably coupled. When a bottom end of the arms 140, as they are being moved from an extended position to a contracted position, come into contact with the wheel locking control mechanism 510, a switch is triggered which engages the wheel locking mechanism 520. When the arms 140 are moved from the retracted position to an extended position, the wheel locking control mechanism is triggered again and disengages the wheel locking mechanism 520. Thus, the wheel locking control mechanism 510 controls whether the set of wheels, or a single wheel, is locked or unlocked.
In embodiments, the wheel locking mechanism 520 cannot be extended and retracted without the extendable handle 110 being moved from retracted position to an extended position. Thus, when the locking mechanism 130 is in a locked state and prevents a button 120 from being depressed, the locking mechanism 130 also controls whether the wheel locking mechanism 520 is engaged.
Step 520 provides that a locking mechanism disposed on the extendable handle is locked. The locking mechanism may be locked by inserting and turning a key to a locked position. Alternatively, the locking mechanism may be a combination lock. The locking mechanism prohibits the handle from being moved from the retracted position to an extended position. According to embodiments, the locking mechanism may prevent a button, a plurality of buttons, a lever, a switch or a knob from being triggered and moving the extendable handle from a retracted position to an extended position. Thus, because the button cannot be depressed, the extendable handle cannot be extended.
To enable the extendable handle to move from the retracted position to the extended position, the locking mechanism may be unlocked. The locking mechanism may be unlocked by either inserting and turning the key or by entering the correct combination depending on the implementation. Once unlocked, the button may be depressed and the handle moved from the retracted position to the extended position. Alternative embodiments provide that the locking mechanism such may also control a wheel locking mechanism such as described above with respect to
