The pendulum member is upright and disengaged from the positioning slot when the luggage is upright. Further, towing the luggage forwardly, obliquely will cause a portion the lower section of the pendulum member to enter in the positioning slot by pivoting due to gravity so as to limit the caster to move forwardly.

Abstract: A reinforced arrangement for a handle assembly of wheeled luggage is disclosed. The handle assembly comprises two units each having a support tube and a sliding tube. The reinforced arrangement comprises an abutment mechanism under the sliding tube, a fixed pin for fastening the abutment mechanism and the sliding tube together, and a reinforced pin in the abutment mechanism urged against a wall of the sliding tube. Responsive to fully extending the sliding tubes for forming an H-shaped reinforced structure on portions of the wall of each sliding tube being in contact with the reinforced pin at about an opening of a bezel. That is, reinforcement is formed at points of external force exerted on the sliding tube while towing the luggage along a supporting surface for preventing the sliding tube from being bent or deformed.

Abstract: A bezel of luggage comprises a vertical portion, a horizontal portion, a first recess surrounded by the horizontal portion and the rear lower side, and a second recess surrounded by the front upper side and the vertical portion. This can protect fingers and thumb in the handle retracting process. This is because there is a sufficient space left between handle grip and second recess and between handle grip and first recess respectively when handle grip is fully retracted onto bezel.

Abstract: A power switching device mounted on an electric scooter is provided. The device comprises a coupling mechanism including a seat and an n-shaped connection member, a switching mechanism including a bent lever, an elastic mechanism, and a drive mechanism. The lever is operable to quickly switch the switching mechanism in one of an engaged locked state when the scooter is manually operated, a disengaged limited state, and a disengaged locked state both when the scooter is battery-operated.

Abstract: A locking device for handle assembly with multiple stages wherein a lock member of higher lock may move into the lock hole of the next lower lock for causing a lock pin of the next lower lock to disengage. Further, there is no horizontal component force created on the slope because the lock member of the higher lock inserts into the lock hole of next lower lock as well as higher lock and next lower lock are engaged in a planar surface. This ensures that there is no gap between the higher and next lower lock such that the fully retracted handle grip may rest on the bezel.

Abstract: A retractable handle assembly of luggage comprises a single handle rod extended upward from a center at a joining edge of a top and a rear of luggage and having an upper portion and a lower portion connected to the rear; and a handle grip extended at a predetermined range of angle about a horizontal plane from a top of the handle rod toward a side of the luggage being perpendicular to the top or the rear of luggage in an unused position. An orientation of a hand holding the handle grip is parallel to a moving direction of the luggage being towed for facilitating an exertion of user's force thereon, thereby lowering a center of gravity of luggage for saving labor.

Abstract: A handle grip of a trunk comprising an upper cover unit and a seat unit receiving in the upper cover unit. Thereby, the seam of the seat unit and the upper cover unit are placed on a top of the handle grip and the stomach portion of the seat unit has no seam. Therefore, when it is held, the hand of the user will not be in contact with the seam of the seat unit and the upper cover unit so as to have a preferred handling feeling.

Abstract: A locking device for handle assembly with multiple stages wherein lock member of first locking means is provided at the bottom of housing of the first locking means capable of directly moving into the lock hole of the second locking means for causing lock pin of the second locking means to disengage; and lock member of second locking means may move into the lock hole of the third locking means for causing lock pin of the third locking means to disengage. As such, lock member of higher locking means may move into the lock hole of the next lower locking means for causing lock pin of the next lower locking means to disengage. Further, there is no horizontal component force created on the slope because the lock member of the higher locking means inserts into the lock hole of next lower locking means as well as higher locking means and next lower locking means are engaged in a planar surface.

The length of the fully extended handle is expected to be longer than the height of the luggage body so as to provide the user with a luggage handle which can be extended to a sufficient height to meet the user's various towing needs.

Abstract: A handle assembly of luggage comprises a handle grip with a push button, two first sliding tubes, at least one pair of second sliding tubes, two supporting tubes, two first locking devices, each provided below each first sliding tube, at least one pair of jumping means, at least one pair of second locking devices, each having a spring receptacle provided below each second sliding tube, a pair of first connecting means attached between the handle grip and the first locking devices, and at least one pair of second connecting means for controlling the second locking devices. The first sliding tubes, the second sliding tubes, and the supporting tubes are activated at positions irrelevant to their respective lengths due to the provision of the second locking device at the bottom of the second sliding tube.

Abstract: A bezel of luggage comprises a vertical portion, a horizontal portion, a first recess surrounded by the horizontal portion and the rear lower side, and a second recess surrounded by the front upper side and the vertical portion. This can protect fingers and thumb in the handle retracting process. This is because there is a sufficient space left between handle grip and second recess and between handle grip and first recess respectively when handle grip is fully retracted onto bezel.

Abstract: A handle assembly for wheeled luggage comprises a handle grip with a push button, a pair of identical outer tubes, a pair of identical inner tubes slidingly engaged with the outer tubes, and a pair of locking mechanisms each having a locking pin connected to an end of an inner tube wherein the disengagement of locking pins from the corresponding slots in a stowed-away position, partially extended position, or fully extended position is carried out by pressing the push button to cause a flexible steel cable in either inner tube connected between the locking pin and the push button to move the locking pin completely within the corresponding slot.

Abstract: A safety mechanism for bezel of luggage with retractable handle is disclosed. Safety device is implemented as a vertically movable F-shaped mechanism in the bezel. F-shaped mechanism is moved down into bezel as handle grip is pressed down until handle grip is locked by a locking device. Further, F-shaped mechanism is automatically returned to a predetermined position when the hand of user is off the F-shaped mechanism. The locking device of handle is deactivated when F-shaped mechanism is pressed down to a predetermined position while retracting the handle. And in turn, handle is automatically bounced up a predetermined sufficient height for facilitating user to pull the handle thereafter. Most importantly, user is prevented from being hurt while retracting the handle.
