Background technology

Multiple pad lock structure and extensively employing of quilt individual have been developed, to prevent that unwarranted people is near any special article or the zone that have been closed and have locked.Although many locks all are configured to open by key, developed multiple combination lock structure by knowing that particular number is opened.

Because it uses easy and convenient and popular a kind of particular number lock is such combination lock, this combination lock adopts a plurality of rotatable independent figure discs, each figure disc forms one of mark (normally numeral or letter), and these figure discs comprise the number that is used to remove lock.Usually, combination lock has user can set or the reset pattern or the position of number sequence of expectation.Although the lock of this general characteristic has been used decades and has been configured to various ways and shape, the combination lock structure of these prior aries has the common defects that is not also successfully overcome.

In the most prior art structure, combination lock is combined with J-shaped or U-shaped shackle, and this shackle is used to provide the expectation with treating blocked suitcase or article to engage.In a most general application,, shackle is inserted be passed in the hole that forms in the zipper head that is installed on suitcase for suitcase being remained on fixing and latched position.Although most of suitcases or similar products (they are combined with the slide fastener that is used for its mating part is remained on make position) use the padlock that is combined with J-shaped or U-shaped shackle to lock by the owner, but recently a popular set product is such lock construction, and this lock construction is designed to receive and secure independently be installed on suitcase or similar products two separately and independently zipper heads.Like this, can use the easier pad lock structure (and this forms contrast with the independent and independent component that hangs from product) that is attached in the suitcase main body to lock suitcase or similar products securely.

Be combined with the structure that can be easily distinguishes with the prior art padlock that is combined with traditional shackle although be configured for directly receiving and securing therein the combination lock of zipper head, be equal to usually and about the prior art problem of rotatable figure disc/zipper head padlock about the prior art problem of rotatable figure disc/shackle padlock.As a result, many manufacturers attempt to solve and rotatable figure disc or the relevant problem of combination lock.

In first preferred implementation of the present utility model, as shown in figure 1 to figure 13, zipper head locking system 10 also is combined with zipper head locking bolt work 80 and 90 except above-mentioned parts.With described, zipper head locking bolt work 80 is configured to move independently with respect to zipper head reception area 14 as shown here, and zipper head locking bolt work 90 is configured to move independently with respect to zipper head reception area 15.For this reason, zipper head locking bolt work 80 and 90 all is configured to be laterally moved in the zone that is limited by reception area 14 and 15 and transverse movement goes out this zone, so that each zipper head locking bolt work 80 and 90 can engage securely with the hole in being formed on the associated zipper pull head, thereby zipper head is firmly held on the housing 12, if the while also can break away from from it when expectation discharges zipper head.

Shown in clear in institute's drawings attached, zipper head locking bolt work 80 and 90 includes a body that is installed in the elongated longitudinal extension in the housing 12, so that door bolt part 80 and 90 can move along the controlled direction of expectation.For this reason, zipper head joint element 85 and 95 forms door bolt part 80 and 90 parts, and the direct insertion of representative door bolt part 80 and 90 is formed on the parts in the hole in the zipper head, and the locking that is used for control zipper head when expectation engages and release.All the other structures of fastening part 80 and 90 with a bolt or latch are used to provide the desired motion of zipper head joint element 85 and 95.

As below describing in detail more fully, when zipper head being inserted in zipper head reception area 14 and 15, zipper head joint element 85 and 95 advances automatically to become with the hole locking of each zipper head and engages.Realize that by the biasing force that provides by the spring part 160 and 170 that acts on the door bolt part 80 and 90 this automatically locks joint.

In order to realize the expectation controlled motion of zipper head locking bolt work 80 and 90, locking system 10 is combined with the control panel 60 as the critical element that is used to realize this desired motion.To describe in detail more fully as shown and below, control panel 60 stops zipper head locking bolt work 80 and the 90 any transverse movements in latched position effectively, simultaneously whenever control panel 60 shifts out and fastens with a bolt or latch stopping of part 80 and 90 when concern, make fasten part 80 and 90 with a bolt or latch can transverse movement.

For this reason, when using key control lock bonding part 18, flange 111 arcs of the plate 110 of cylindrical shell 100 are pivoted into the part of control panel 60 and directly contact so that control panel 60 from move out door bolt part 80 and 90 locking engage, fasten part 80 and 90 with a bolt or latch and can in housing 12, move thereby make.In addition, in case realized this latch-release, the radially adjutage 112 of the plate 110 of cylindrical shell 100 direct contact door bolt part 80 just then so that door bolt part 80 and 90 all moves in housing 12, thereby make zipper head joint element 85 and 95 all from the engaging of associated zipper pull head move out.Like this, the arc pivoting action in response to cylindrical shell 100 discharges zipper head immediately.

In addition, as below describing in detail more fully, when using number control lock bonding part 17, sliding part 50 just moves with the motion of direct control control panel 60, thereby discharges stopping door bolt part 80 and 90.In addition, when control panel 60 from the stopping when moving out the relation of door bolt part 80 and 90, the continuation campaign of sliding part 50 just causes directly contacting with 90 with door bolt part 80, so that door bolt part 80 and 90 moves in housing 12, engage with the locking of associated zipper pull head thereby discharge zipper head joint element 85 and 95 effectively.Like this, in response in number control lock bonding part 17, having imported predetermined number, discharge zipper head immediately.

As describing in detail as can be known from the front, by adopting number control lock bonding part 17 or key control lock bonding part 18, locking bolt work 80 and 90 zipper head joint element 85 and 95 are controllably discharged when expectation, thereby make any zipper head attached to it break away from, to open suitcase, briefcase or other products from locking system 10.In addition, as below will describing in detail more fully, when expectation, the user can insert the zipper head of expected product in the locking system 10, so that zipper head is bonded in the system 10 securely, thereby is bonded with each other with the locking of current prestige in fact.

In the preferred structure of this embodiment of the utility model, number control lock bonding part 17 comprises that a plurality of marks carry rotatable figure disc 21,22 and 23, are used to set and import the expectation number that is used for the locking and unlocking zipper head locking system 10.In order to make the user can easily show any desired number, housing 12 preferably includes formation viewing area thereon, is used to make the mark that is formed on the rotatable figure disc to see easily.Usually, structure detailed is similar in the structure of number control lock bonding part 17 and the United States Patent (USP) 6,408,660, and its relevant portion is incorporated herein by reference.

As shown, rotatable figure disc 21,22 and 23 is all installed with a clutch ring 31,32 or 33 cooperations relatedly.In addition, for keep clutch ring 31,32 and 33 and figure disc 21,22 and 23 be frictionally engaged, spring part is associated coaxially with each assembly, keeps being frictionally engaged continuously required biasing force to be provided for making the relative figure disc of each clutch ring.Like this, figure disc 21,22 and 23 makes clutch ring 31,32 and 33 therewith move rotatably about rotatablely moving of its central axis.

Although it is following and at United States Patent (USP) 6,408, figure disc 21,22 and 23 and the clutch ring 31,32 that cooperates and 33 detailed structure and operation have been described in detail in detail in 660 fully, but answering an architectural feature of important attention is to be combined with groove 31a, 32a and the 33a that is formed in each clutch ring 31,32 and 33.As describing in detail here, the rotation of each clutch ring 31,32 and each groove 31a, 32a of 33 and 33a and figure disc 21,22 and 23 is the locking and unlocking of control system 10 in combination.

In order to provide expectation locking and the controlled release of zipper head from zipper head joint element 85 and 95 when using number control lock bonding part 17, number control lock bonding part 17 is combined with lockplate 40.In its preferred structure, lockplate 40 is combined with finger 41,42 and 43, each finger all be formed on clutch ring 31,32 and 33 in groove 31a, 32a and one of 33a aim at.In addition, lockplate 40 by spring part 121 and 122 continuous bias voltages engaging with clutch ring 31,32 and 33, thereby punctual whenever groove 31a, 32a and 33a and 41,42 and 43 pairs of fingers, lockplate 40 is moved into automatically with clutch ring engages.

When all three grooves are arranged to when all three fingers become aligned relationship (just realizing when this has only imported the preset number of expectation on rotatable figure disc 21,22 and 23), lockplate 40 since apply thereon spring force and motion automatically.But whenever input on figure disc 21,22 and 23 during incorrect number, one or more among relevant clutch ring 31,32 and 33 groove 31a, 32a and the 33a are located in the position with one of the relevant finger 41,42 of lockplate 40 and 43 misalignment.As a result, lockplate 40 can not move, thereby makes locking system 10 remain on latched position.

As mentioned above, in case lockplate 40 motion in housing 12, the flange 44 of lockplate 40 just moves out from engage with stopping of the gap of sliding part 50 or cutout regions 51.As a result, sliding part 50 is released, thereby can transverse movement in housing 12.

In preferred structure, as shown in FIG., locking system 10 is combined with the button 140 that is fixed in sliding part 50 by screw 131.As a result, in case lockplate 40 motions, the user just can utilize button 140 to make sliding part 50 transverse movement in housing 12.Along with sliding part 50 transverse movements, the beveled edge surfaces 52 of sliding part 50 contacts with the beveled edge surfaces 61 of control panel 60.The joint of these two inclined surfaces makes control panel 60 along moving towards the direction of lockplate 40 and figure disc 21,22 and 23, thereby makes the stop edge 62 and 63 sidewalls 91 and 81 from locking bolt work 90 and 80 of control panel 60 break away from.

In addition, along with sliding part 50 continues transverse movements housing 12 in, in contact and make after control panel 60 moves, the edge 53 of sliding part 50 contacts with 82 with 80 surface 92 with locking bolt work 90 with 54.In preferred structure, edge 53 is configured to surface 82 spaced apart 55, and edge 54 and surface 92 spaced apart 56.Because this structure, formed built-in delay zone, allowing inclined surface 52 touch panels 60 of sliding part 50, and edge 53 with 54 with locking bolt work 80 and any contact of 90 before the required motion of realization control panel 60.

As a result, before sliding part 50 and door bolt part 80 and any contact of 90, removed control panel 60 and engaged with stopping of locking bolt work 80 and 90.Like this, door bolt part 80 and 90 can in response to the engaging of sliding part 50, antagonistic spring spare 160 and 170 biasing spring power and transverse movement in housing 12.As a result, zipper head joint element 85 and 95 is removed from relative zipper head, engages with the locking of housing 12 thereby discharged slide fastener effectively.

In preferred structure, zipper head locking system 10 also is combined with two barrier plates 70, each barrier plate and locking bolt work 80 and 90 and one of zipper head joint element 85 and 95 be associated.In addition, as shown in FIG., each barrier plate 70 is associated with spring 150, and this spring 150 applies biasing force to barrier plate 70 continuously along the direction towards zipper head joint element 85 and 95.As a result, whenever locking bolt work 80 and 90 moves to the off-position, make zipper head joint element 85 and 95 when relative zipper head withdraws from, barrier plate 70 just makes zipper head eject and from its automatic release.

In addition, for this reason, as shown, the lateral edges 71 of barrier plate 70 and locking bolt work 80 and 90 zipper head joint element 85 contact with 93 with 95 surface 83, thereby prevent to fasten with a bolt or latch any motion of part 80 and 90.
