When the handle is not in use, the user pushes the handle down and rotates the handle in a reverse direction to transit it from the vertical position to a horizontal position; thereby, pushing the handle horizontally into its preserving recess on the top of the luggage body.
Description
- 1. Field of the Invention
- The present invention relates to a luggage handle and more particularly to a horizontally retractable luggage handle of wheeled luggage.
- 2. Description of Related Art
- Conventionally, a retractable handle is disposed vertically inside the rear portion of a luggage piece and can be retracted into the bezel provided on the top of the luggage so that only the top portion of the handle grip is revealed to the user. However, by using such a design, the available storage space inside the rear portion of the luggage is relatively reduced. By complying with the Warsaw Convention, i.e., to maintain the safety of air transportation and air travel, the exterior of luggage has to be smooth and nonprotruded; therefore a luggage's handle assembly has to be concealed inside the luggage body. Since an internal concealment space for the luggage handle is indispensable, the corresponding sacrifice for precious available storage space in the luggage also becomes inevitable, if the retractable handle mechanism is to be retracted and concealed vertically inside the luggage. Thus, there is a need for a new horizontally retractable luggage handle design.
- An object of the present invention is to provide a horizontally retractable handle for wheeled luggage such that when the handle is not in use, it can be retracted into and stored in a top chamber inside the luggage so that the luggage's loading capacity can be increased by sparing more upright storage space for the user.
- Another object of the present invention is to provide a horizontally retractable handle for the wheeled luggage such that the new design can provide the advantages of component simplicity, convenience, practicality, and durability.
- The above and other objectives, features, and advantages of the present invention will become apparent from the following detailed description made in conjunction with the accompanying drawings.

The important feature of the present invention is to provide a horizontally retractable handle device of wheeled luggage on a top chamber of the luggage, wherein the handle is slidable along two horizontal grooves extending from the rear top to the front top of the luggage. The retractable handle device comprises a handle grip; a pair of sliding tubes, which are slidable along the two horizontal grooves on the top of the luggage, wherein the front ends of the sliding tubes are connected to the handle grip; and a pair of locking devices provided at the front portion of the two horizontal grooves.
- With all these composing members stored in place, the user first pulls out the luggage handle horizontally to the front-most position, then, with one move, rotates the rear end of each of the said pair of sliding tubes and causes the locking device to move downward. Accordingly, the luggage handle changes its orientation from a horizontal position to a vertical position. Upon changing the orientation of the luggage handle at a predetermined position, the pair of locking devices would lock the pair of sliding tubes in place, thereby securing the luggage handle into a position readied for the user's towing operation.
- FIG. 1A shows the
handle 50 retracted into the top chamber of theluggage 10. The user may pull thehandle 50 out and change the orientation thereof when the handle is in use (FIGS. 1B to 1E). FIG. 2 shows the fullyextended handle 50 being carried by a person. It is noted that the locking device and the locations of the associated locking holes (i.e., the locking mechanism provided in the outer sliding tubes and the inner sliding tubes) are a prior art, therefore a detailed description related to the subject is omitted here for the sake of brevity. - FIGS. 3a to 8 show the preferred embodiment of the
luggage handle 50 comprised of an outersliding tube 51, an innersliding tube 52, asleeve 54, and ahandle grip 53 on the top of thehandle 50. Note that one side ofhandle 50 is a mirror of the other side thereof, so that the description of one side of thehandle 50 serves to describe thewhole handle 50. - The horizontally retractable handle assembly of luggage comprises a
handle 50, asleeving member 20 sleeved onhandle 50, agroove 11 for allowinghandle 50 to slide therein, ahandle locking device 40, and anarcuate guide groove 13 for controlling the orientation of thehandle 50 when it is retracted. Anenlargement 510 is provided on the bottom end of the outersliding tube 51. Theenlargement 510 is slidable along thegroove 11. Thesleeving member 20 is disposed between thegroove 11 and the outersliding tube 51. Thesleeving member 20 is sleeved on thehandle 50 and has a smallerfront end 24 and a largerrear end 25, so that theenlargement 510 may move through thelarger end 25 until it is stopped at the smaller end 24 (FIG. 4A). Apivotal block 23 and acenter block 22 are provided on the external surface of thesleeving member 20. Thepivotal block 23 and thecenter block 22 are moveable in theguide groove 12 on the top of the luggage. Theguide groove 12 has a straight rear portion. Anarcuate guide groove 13 is at the front of theguide groove 12 to allow thepivotal block 23 to rotate therein. Adent 131 is provided at the rear end of theguide groove 13. Adent 121 is provided beneath thedent 131, and anarcuate recess 122 is provided opposite to thedent 121 for permitting thecenter block 22 to rotate therein. - The horizontally retractable handle's
locking device 40 is designed partly to let the handle 50 rotate from a horizontal position to a vertical position and lock thehandle 50 in the vertical position. The handle'slocking device 40 is located at the front portion of the top chamber of theluggage handle 50 and is just below therecess 122 whenhandle 50 is fully retracted into its horizontal casement at the top of the luggage. As shown in FIGS. 3C and 3D, the handle'slocking device 40 comprises asolid locking block 411 in the center, aspring 410 biased against the bottom of thesolid locking block 411, ahollow locking block 42 surrounding thesolid locking block 411, twosprings 420 biased against the bottom of thehollow locking block 42, twosprings 420, which are sleeved one on each of the twopedestals 421 extended down from the two sides of the top portion of thehollow locking block 42, and a casement 43 (see FIG. 3D). Thecasement 43 has awide notch 432, anarrow notch 4321, aconcave slope 431, and twohollow cylinders 433 extended down from the lower portion of thecasement 43. The twopedestals 421, which extend down from the two shoulders of the main block of thehollow locking block 42, serve to assure a smooth descent of theblock 42 itself. Each of thepedestals 421 is equipped with three-sectionedflanges 4212 and threeslits 4211 evenly deployed amongst the threeflanges 4212. These arrangements are provided to make way for the twopedestals 421 to insert themselves into the fixingholes 434 within the twocylinders 433 of the casement 43 (see FIG. 3D) so as to facilitate the manufacturing and assembling of the part. Thesolid locking block 411 consists of two portions on two opposite sides of the part. The first portion, which is at the front face, includes a large bulk with a trapezoidal side profile. This portion is provided for interacting with theenlargement 510. The second portion, which is on the back side of thelocking block 411, includes a smaller block with a trapezoidal side profile and two vertically allocated board-like pieces provided at the two vertical edges, respectively, of thelocking block 411. The piece with a trapezoidal side profile is located at the center-top of the back face, and it serves to interact with thehollow locking block 42. The other two vertically allocated board-like pieces serve as the sliding tracks for thelocking block 411. Thehollow locking block 42 contains three portions, which are mutually separate on top and connected together at the bottom. While the two side shoulders are responsible for wrapping up the two stretched-downpedestals 421, the one central piece between them interacts with thesolid locking block 411. - As shown in FIGS. 3A to3D, the left part of the
solid locking block 411 extends into thehollow locking block 42 such that thehollow locking block 42 may move downward as thesolid locking block 411 moves downward. But thehollow locking block 42 cannot move downward if it is the only member which is pushed down, because the compression force will be neutralized by the little notch located to the left of thehollow locking block 42 upon the locking device's 40 casement 43 (see FIGS. 3A, 3C, and 3D). When handle 50 is pulled out from its recess position (a first position, as shown in FIG. 3A) to its horizontal active position (a second position, as shown in FIG. 4A), thesleeving member 20 first contacts the blunt tip of thesolid locking block 411, which in turn causes the locking device;s 40 two acting elements, thesolid locking block 411 and thehollow locking block 42, to move downward. Thesleeving member 20 moves to its front most position when the outer slidingtube 51 is fully extended. At this instant, thepivotal block 23 and thecenter block 22 are located at the bottom of thearcuate guide groove 13 and the bottom ofdent 121, respectively (see FIG. 4A).Handle 50 is further pushed to move from its horizontal position toward its vertical position (as shown in FIGS. 4 to 6), wherein thepivotal block 23 and thecenter block 22 are rotated along theguide grooves 12 and 13 (FIG. 5) until they reach their positions shown in FIG. 6. At this instant, thehandle 50 is held at its vertical position when thepivotal block 23 and thecenter block 22 are being received into thedents tube 52 out by pressing thebutton 531 on thehandle grip 53 until the inner slidingtube 52 is fully extended. This time thehandle 50 is protracted to its maximum length (FIG. 7), and consequently the user may pull the luggage along the ground. - FIG. 8 shows an erectly retracted
handle 50. The following narrative will describe the retractable handle's operating procedure and discuss how exactly thehandle locking device 40 works when the user tries to convert the retractable handle from its vertical position to a horizontal position and push it into its horizontal recess on the top of the luggage. The user can push it back into its horizontal recess by first pressing thehandle grip 53 down. The handle's inner slidingtube 52 will then be pushed downward, as shown in FIG. 8, and the bottom of theenlargement 510 at the bottom end of the outer slidingtube 51 will contact the solid locking block's 411 blunt tip. At this moment, the block's 411 blunt tip is at its highest position. Due to the action of the solid locking block's 411 allocatingspring 410, thesolid locking block 411 will descend. Please refer to FIGS. 3C and 3D, specifically. Before thesolid locking block 411 is pushed down, as shown in FIG. 7, thehollow locking block 42 is caught on thewide notch 432 provided at the lower edge center of theconcave slope 431 inside the handle'slocking device 40, having no way to maneuver. When the tip of thesolid locking block 411 is pushed down and descends to almost the same height as thehollow locking block 42's top platform, the hollow locking block's 42 major reacting element (the little piece at the top-center), being compressed and temporarily deformed by the pressure from the bottom of theenlargement 510, moves toward thesolid locking block 411 and relieves itself from thenarrow notch 4321 located at the lower edge center of theconcave slope 431 oncasement 43. Concurrently, the twosprings 420, which are curled around the hollow locking block's 42 twopedestals 421, will be compressed to allowblock 42 to descend. Thus, both thesolid locking block 411 and thehollow locking block 42 are able to descend. At that time, thepivotal block 23 and thecenter block 22 are also released from theirrespective dents enlargement 510 and thesleeving member 20 both move counterclockwise (see FIG. 5) from their original vertical active positions to the horizontal inactive positions. Thehandle 50 is further pushed in until it is fully retracted into its horizontal storage space on the top of the luggage (see FIGS. 4A, 3B, and 3A). - It is appreciated by those skilled in the art that, in another embodiment, the
sleeving member 20, thepivotal block 23, thecenter block 22, and theguide grooves center block 22 and the pivotal block 23) and the L-shaped guide groove is provided along the inner wall of thegroove 11 and extended from the rear to the front portion of thegroove 11. Whenever the user tries to pull the horizontally retractable handle out to its operating position (i.e., to change the handle's orientation from its original inactive horizontal position to its active vertical position), the spring-biased member will be protruded along the L-shaped guide groove and be further protruded and locked in a locking device when the handle is pull out in its vertical position. When the user tries to deactivate the retractable handle from its vertical position and put it back to its horizontal storage space, the user pushes a button on the handle grip and the spring-biased guiding member will be retracted and be pushed down accordingly. By following a reverse procedure, the handle will be retracted. - While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
