Abstract:
A safety mechanism of luggage with a retractable handle assembly including a handle grip, a pair of sliding tubes having an upper hole, and a bezel having a concave member having a tunnel on either side for permitting each sliding tube to slide therein, a vertical plate, a seat plate, and a top plate, the safety mechanism comprising:an elongate transverse groove between the vertical plate and the top plate of the bezel; an elongate recessed engagement mechanism abutted on the sides, the bottom, and the rear of the transverse groove, the engagement mechanism including a bottom portion, a vertical portion, two spaced posts on the bottom portion, two first spring put on the posts, a guide in a front of the posts, and an elongate vertical recess at two sides of the vertical portion of the engagement mechanism; an F-shaped mechanism being vertically movable in the engagement mechanism; wherein in a fully retracted position of the handle grip, the first springs are urged against and to push the F-shaped mechanism upward to engage with an underside of the top plate of the bezel; a locking device at two sides of the engagement mechanism including a socket at two sides of the bottom portion of the engagement mechanism, the socket including a bottom opening, a top opening, and a front opening; the F-shaped mechanism including an upper horizontal portion, a vertical portion, an extension horizontally extending from both sides thereof, a flange on the top of the extension, a central divider below the horizontal portion, a recessed portion at two sides of the central divider such that the posts are capable of passing through recessed portions when the F-shaped mechanism is moving vertically, and the bottom of the vertical portion of the F-shaped mechanism is capable of moving into a guide through the transverse groove; two spaced tube members with notched circumferential surface at the underside of the top plate of the bezel; two spaced slots at the vertical portion of the engagement mechanism such that the engagement mechanism is capable of being secured to the top plate of the bezel by driving fasteners through the tube members and the spaced slots; a flexible latched member in two undersides of the seat plate of the bezel being clung to the bottom opening of the socket such that the F-shaped mechanism is capable of moving vertically with the flanges on the top of the extension being slidably received in the recesses of the engagement mechanism; a wedge at the underside of two extension of the F-shaped mechanism, the wedge including a front planar portion and a rear slanted surface; a locking block in the socket, the locking block including a recessed slanted surface on an upper surface, a rear peg, a spring loaded on the rear peg, and a front stud; and a bouncing device at the lower part of each sliding tube, the bouncing device including an upper frame member, a lower abutment member held by the upper frame member, a sliding block having a catch within the lower abutment member, and a second spring anchored in the lower abutment member, whereby pull the handle grip to activate the bouncing device to push each sliding tube upward to cause the handle grip to bounce a predetermined distance above the top plate of the bezel; and press down the handle grip to cause the F-shaped mechanism to move down simultaneously thus forming a space in the bezel by the downward moved F-shaped mechanism.
