BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a luggage, and more particularly to a handle for a luggage.
2. Description of Related Art
Typically, a conventional luggage is provided with a U-shaped handle pivoted on a case. The handle is leaned down on the case normally, and user has to grip it upwards to carry the luggage. A drawback the conventional handle is that it is free to rotate, so that the handle will move unexpectedly when a user move the luggage.
An improved handle of a luggage is made of a flexible material. The improved handle will be attached to a case normally, and a user may grip it outwards to carry the luggage, and the handle will return automatically when the user does not grip it. Such handle is easy to be broken since the handle is moved relative to the case repeatedly.
BRIEF SUMMARY OF THE INVENTION
In view of the above, the primary objective of the present invention is to provide a handle for a luggage, which has a strong structure and a great flexibility to have a stable operation and a great loading, and furthermore, it has a good looking.
In order to achieve the objective of the present invention, a handle, which is adapted to be mounted on a surface of a case, includes a main member having a hollow portion, wherein the hollow portion has a plurality of alternate spacers and recesses, and an elastic member passing through the spacers and the recesses and having opposite ends fixed to the main member. The main member is moved away from the surface of the case and the elastic member is deformed when a user holds the main member to lift the case, and the main member is moved to an initial position by the elastic member when the user releases the main member.
In an embodiment, the handle further includes two connecting arms connected to opposite ends of the main member and two connecting devices connected to the case. The connecting devices may be a combination of a base and a lid or a combination of a cover and an extending board to movably connect to the connecting arms.
In an embodiment, the main box is provided with at least a rib, or at least a concave portion to enhance a strength thereof.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, a handle 20 of the first preferred embodiment of the present invention is mounted on a surface 12 of a case 10 through two connecting devices 40. The connecting devices 40 have the same structure, so we only describe one of them hereafter.
As shown in FIGS. 2 and 3, the handle 20 includes a main member 22 with two transmission assemblies 24 at opposite ends thereof. The transmission assemblies 24 are connected to the connecting devices 40 respectively. Each of the transmission assemblies 24 includes a connecting arm 26, a block 28 connected to the connecting arm 26, and a sliding rod 30. Opposite ends of the sliding rod 30 are projected from the block 28.
As shown in FIG. 4, each of the connecting devices 40 includes a base 42 and a pair of parallel rails 46 on a bottom 44 of the base 42. Each of the rails 46 has an inclined portion 48 at an end thereof The base 42 has a slot 50 on the bottom 44 between the rails 46 and two first tubes 52 projected from the bottom 44 at ends of the rails 46 opposite to the ends having the inclined portions 48. Each of the connecting devices 40 further includes a lid 54 connected to the base 42.
As shown in FIGS. 4 and 5, each of the lids 54 has a first side 56 and a second side 58 opposite to the first side 56. The first side 56 is inclined. The lid 54 has a through hole 60 having opposite ends thereof open at the first and the second sides 54, 56, two second tubes 62 on the second side 56, and two stop blocks 64 on the second side 56 beside the second posts 62 respectively. Each of the stop blocks 64 has an inclined portion 66 at an end.
As shown in FIG. 6, the lid 54 is connected to the base 42 with the second side 58 facing the bottom 44 of the base 42. The second tubes 62 of the lid 54 are coupled to the first tubes 52 of the base 42 by suitable fasteners, such as bolts or screws. The stop blocks 64 correspond to the rails 46 and keep a movable space 68 therebetween. The connecting arms 26 respectively pass through the through holes 60 of the lids 54 with the blocks 28 received in the slots 50 of the bases 42 and the sliding rods 30 on the rails 46.
As shown in FIGS. 2 and 7, the main member 22 has two hollow portions 70, each of which has a plurality of alternate spacers 72 and recesses 74. Two elongated elastic members 76 pass through the spacers 72 and the recesses 74 respectively. Opposite ends of the elastic members 76 are coupled to the main member 22 to make the main member 22 flexible. In an embodiment, the elastic members 76 are two metallic cables.
In an embodiment, the main member 22 and the connecting arms 26 are made of a flexible material, and the metallic cables are embedded in the main member 22 to make the main member 22 flexible. The flexibility of the main member 22 and the elastic members 76 will attach the main member 22 to the case 10 initially.
As shown in FIG. 8, when a user holds the main member 22 of the handle 20 to lift the case 10, the blocks 28 on the connecting arms 26 move toward the lids 54, and the sliding rods 30 move on the rails 46. At this time, the sliding rods 30 are raised by the inclined portions 48 of the rails 46, and moved to the movable spaces 68 under the through holes 60. Since lengths of the sliding rods 30 are greater than the through holes 60, the connecting arms 26 and the sliding rods 30 are restricted in the connecting devices 40. The main member 22 of the handle 20 is moved away from the surface 12 of the case 10, and the main member 22 and the elastic members 76 are deformed to generate a recover force because of the flexibility.
The recover force of the main member 22 and the elastic members 76 will return the main member 22 automatically when the user releases the main member 22 of the handle 20. At this time, the sliding rods 30 move on the rails 46 until the blocks 28 are received in the slots 50.
The hollow portions 70 of the main member 22 and the elastic members 76 provide the main member with good flexibility and strength. Furthermore, the main member 22 has a fancy appearance. The sliding rods 30 move on the rails 46 to the movable spaces 68, so that the handle 20 of the first preferred embodiment may provide a stable and large loading. Besides, the first side 56 of the lid 54, on which the through hole 60 is provided, is inclined that benefits the connecting arm 26 through the through hole 60. The inclined portion 66 of the stop block 64 may guide the sliding rod 30 to the movable space 68.
FIG. 9 shows a handle of the second preferred embodiment of the present invention, which is the same as the first preferred embodiment, except that the main member 22 is provided with two connecting arms 80 and two connecting devices 90. The main member 22 has the hollow portions 70, the recesses 72, and the elastic members 76. Each of the connecting arms 80 is provided with a sliding hole 82 through the connecting arm 80.
As shown in FIGS. 9 and 10, the connecting device 90 has a cover 92 and an extending board 94. The connecting device 90 further has a through hole 96 between the cover 92 and the extending board 94 and two locking rods 98 on a bottom of the cover 92.
As shown in FIG. 11, the connecting arm passes through the through hole 96 to the bottom of the cover 92. The locking rod 98 passes through the sliding hole 82 of the connecting arm 80 to be fixed to the case 10 by a suitable fastener. When a user holds the main member 22 and lifts it, the connecting arms 80 move together with the main member 22, and the locking rod 98 moves in the sliding hole 82.
When the user releases the main member 22, the recover force of the main member 22 and the elastic members 76 moves the main member 22 toward the case 10. At this time, the sliding hole 82 moves relative to the locking rod 98 in an opposite direction until the main member 22 is attached to the case 10.
It must be pointed out that the embodiments described above are only some preferred embodiments of the present invention. All equivalent structures which employ the concepts disclosed in this specification and the appended claims should fall within the scope of the present invention.
