BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates generally to a luggage lock, and more particularly
to a built-in shackle lock assembly of the luggage.
2. Description of Related Art
[0002] The conventional luggages of all sizes are generally provided with a lock, which
may be a key lock, electronic lock, noncontact lock, combination lock, etc. These
conventional locks may be able to prevent the contents of the luggage from being taken
out by an unauthorized person; nevertheless they can not prevent the luggage from
being moved away from a designated area. In addition, the conventional luggage locks
call for the use of a key, or ID card to work the lock mechanism. In the event that
the key or ID card is lost or misplaced, the luggage locks can not be operated. The
combination lock is an exception by virtue of the fact that it is operated by a dial
that is turned to a set series of numbers or letters to work the lock mechanism.
SUMMARY OF THE INVENTION
[0003] The primary objective of the present invention is to provide a luggage having a built-in
shackle lock assembly which is free of the deficiencies of the conventional luggage
locks described above.
[0004] In keeping with the principle of the present invention, the foregoing objective of
the present invention is attained by a luggage comprising a shell, and a shackle lock
assembly which is disposed in a compartment of the shell. The shackle lock assembly
comprises a shackle, a spring housing, a control lever, a start knob, and a combination
lock. The shackle has a fastening end which is fixed at a shaft of the spring housing.
The spring housing is capable of turning forward and backward so as to unwind and
wind the shackle. The spring housing is provided with a ratchet wheel. The control
lever is provided with a pawl engageable with the ratchet wheel of the spring housing.
The start knob serves to keep the shackle in a locking or unlocking state. The combination
lock is used to controi the start knob.
[0005] The features and the advantages of the present invention will be more readily understood
upon a thoughtful deliberation of the following detailed description of the preferred
embodiments of the present invention with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0007] As shown in FIGS. 1-3, a luggage 1 embodied in the present invention has a shell
which is made of a resin material reinforced by acrylonitrile butadiene styrene (ABS).
The shell is divided into a bottom shell 1A and a top shell 1B, which are fastened
together by means of a zipper 4. The bottom shell 1A is provided at an upper portion
with a hand grip 2, and a compartment H in which an expandable hand grip 3 is disposed.
A shackle lock assembly K is also disposed in the compartment H. The bottom shell
1A is provided at both ends of a bottom portion with a wheel 5 to facilitate the moving
of the luggage 1 on a surface.
[0008] As shown in FIG. 2, the shackle lock assembly K of the present invention is provided
with a lock mechanism which is formed of a combination lock 11, a shackle 12 of iron
cable, a shaft 13 for mounting a spring 14, and a spring housing 15 for winding the
shackle 12. The combination lock 11 is operated by a dial that is turned to a set
series of numbers or letters to work the mechanism that opens the luggage 1. The shackle
12 can be used to disable the zipper 4 so as to prevent the luggage 1 from being opened
up by an unauthorized person. The shackle 12 is fixed at one end with the shaft 13.
The spring housing 15 is provided with a ratchet wheel 15B. The lock mechanism is
further formed of a control lever 16 and a start knob 17. The control lever 16 is
provided with a control rod 16B capable of turning on a pivot 16A. The control lever
16 has a front end which is provided with a connection head 18 capable of turning
on a pivot 16D. The control lever 16 further has a shackle locking piece 19. The pivot
16D is provided with a torsion spring 16E which is used to keep the control rod 16B
and the connection head 18 in alignment at the time when they are not exerted on by
an external force. The control rod 16B is provided in proximity of the pivot 16D with
a pawl 16C capable of engaging the ratchet wheel 15B of the spring housing 15.
[0009] As illustrated in FIGS. 2 and 5, when the control rod 16B and the connection head
18 are held in alignment by the torsion spring 16E, the pawl 16C is engaged with the
ratchet wheel 15B. As a result, the spring housing 15 can not be turned. In the meantime,
the shackle 12 is caught by the shackle locking piece 19. The shackle 12 can not be
thus pulled.
[0010] As shown in FIG. 6, when the control lever 16 is pressed downward, the control rod
16B is caused to swivel upward on the pivot 16A. As a result, the pawl 16C is caused
to disengage the ratchet wheel 15B of the spring housing 15, thereby enabling the
spring housing 15 to be turned. In the meantime, the curvature of the shackle locking
piece 19 is changed so as to release the shackle 12, which can be thus pulled out
via a through hole of a guide portion 20. The shackle 12 can be retracted by pressing
the control lever 16 so as to cause the ratchet wheel 15B to become disengaged with
the pawl 16C. The spring housing 15 is caused by the recovery force of the spring
14 to turn in reverse to effect the retraction of the shackle 12.
[0011] As the shackle 12 is pulled out, a shackle head 12A of the shackle 12 can be inserted
into an engagement port 22. The shackle head 12A is removably held in the engagement
port 22 and can be thus disengaged with the engagement port 22 by activating the start
knob 17, as illustrated in FIGS. 7 and 8. The shackle head 12A is provided with an
annular groove 12B, while the engagement port 22 is provided with a retaining edge
23. The start knob 17 has an inner end, which is urged by a spring 17A. When the shackle
head 12A is inserted into the engagement port 22, the retaining edge 23 is retained
in the annular groove 12B of the shackle head 12A. The inward displacement of the
start knob 17 is controlled by the combination lock 11. In another words, when the
combination lock 11 remains in the locking state, the start knob 17 can not be actuated
to move inward. As a shackle head 12A is in the engagement state, a link pin 30 is
pushed downward such that the link pin 30 is stopped by a projecting part 16F of the
control lever 16. As a result, the control lever 16 remains in the fixed state.
[0012] As shown in FIG. 8, the combination lock 11 is in the unlocking state to enable the
start knob 17 to be actuated to move inward to effect the disengagement of the retaining
edge 23 with the annular groove 12B. As a result, the shackle head 12A can be pulled
out of the engagement port 22. In the meantime, the link pin 30 is caused by the spring
force of the spring 31 to move away from the projecting part 16F of the control lever
16, thereby enabling the control lever 16 to remain in the standby state.
[0013] The compartment H of the luggage shell is provided with a start port 27 and a shackle
operating port 28. The control lever 16 can be actuated by a finger which is put through
the shackle operating port 28. The compartment H is further provided with an exit
port 25 via which the shackle 12 is pulled out. The compartment H is still further
provided with a start-up port 27 via which the start knob 17 can be reached by a finger,
so as to remove the shackle head 12A.
[0014] The zipper 4 is provided with two pull tabs 6, each having a ring 7 dimensioned to
allow passage of the shackle head 12A. As the shackle head 12A is engaged with the
engagement port 22 via a through hole 26 of the compartment H, the zipper 4 is disabled.
[0015] The luggage 1 of the present invention can be thus fastened to a fixed object so
as to prevent it from being taken away by an unauthorized person. In addition, a plurality
of luggages or the like can be securely held together by means of the shackle 12 of
the present invention.
[0016] As shown in FIG. 4, a luggage 1 of a second embodiment of the present invention has
a shell which is made of a polyester material. The shell is different in form from
that of the luggage of the first preferred embodiment as shown in FIG. 1. However,
the luggage of the second embodiment of the present invention is provided with a shackle
lock assembly identical in structure and function with that of the luggage of the
first embodiment of the present invention. In short, the shackle lock assembly is
the subject matter of the present invention.
[0017] The embodiments of the present invention described above are to be regarded in all
respects as being illustrative and nonrestrictive. Accordingly, the present invention
may be embodied in other specific forms without deviating from the spirit thereof.
The present invention is therefore to be limited only by the scope of the following
claim.
