Description

The lockable fixed mechanism of zipper tabs such as suitcase, sack

The present invention relates to the lockable fixed mechanism of zipper tabs such as a kind of suitcase, sack, this mechanism has a latch that compresses that is set at shell one side, and the aperture of draw ring can place on this free end that compresses latch, so that a spring-loaded ejector is applied pulling force, other has one can lock the locking section that enclosure moves, compress latch so that this draw ring is left, lock is actuated to carry out/to stop moving of this locking section.

Existing this type of lockable fixed mechanism, disclosed by Deutsche Bundespatent case DE 41 06 887 A1 numbers, ejector spring and the ejector that energy is exerted pressure by this ejector spring of being designed to compression spring are wherein arranged, be located in regular turn each other and compress on the latch.This perimeter support that compresses latch is lived a spring-loaded locking section, and when draw ring was in the location, the some of this locking section just overlapped on the free end of draw ring.When locking section produces and to do the time spent compressing latch, whenever the free end of draw ring is placed in location-but lock and still be in its lockset position of coupler, the inclined-plane of locking section bolt button promptly is responsible for forcing this locking section to be pivoted to its off-position.But at the same time, this draw ring free end and ejector spring can consequently will overcome the strength of two springs to ejector generation effect, and the beginning can place draw ring to compress on the latch and locate, thereby makes the processing of fixed mechanism become comparatively because of difficulty.

The object of the present invention is to provide the fastening devices of this type, from design viewpoint, this fastening devices is easy to make, handle safety simple, can guarantee height simultaneously after locking.

The technical measures of implementing above-mentioned purpose of the present invention and taking mainly are this lockable fixed mechanism to be set as can utilize an ejector device and locking section is buckled in an off-position, so that draw ring can be left.

Because the result of this kind particular design, thus can impel the problem of the lockable fixed mechanism of this type to solve, thereby with higher utility, and can performance safety highly when locking.If the draw ring of slide fastener is in the snapped-in position that locked section sets firmly, then after this lock was actuated, this draw ring promptly was movable to the off-position.The spring-loaded ejector can be upspring draw ring from compressing latch then, and this ejector can move to the snapped-in position relevant with locking section simultaneously, and locking section is remained on after the off-position.Therefore, when the pulling force of ejector spring during by most removal, the spring relevant with locking section still can remain under the stretching situation.Locate if at this moment draw ring is placed to compress on the latch once again, just so only need to use ejector can overcome the load on spring of executing thereon.Wait this ejector to move to one and bear load on spring and when making itself and draw ring form the position of overlapping relation, the snap effect of this ejector promptly lost efficacy.This declaration of will such as desire place when location with draw ring, only need overcome the strength of a spring, just thereby fixed mechanism of the present invention only need use few strength to lock, so be very comfortable to the user.

Being unlike the prior art, the spring-loaded locking section can overlap onto sizable degree with the free end of draw ring, in addition, if think firmly draw ring to be drawn back from compressing latch, must use instrument to begin and to accomplish, thereby have complexity such as screwdriver or other kind of pry class.

In fact ejector form one can be when locking section be in the off-position card (embedding) go into the bolt that its bolt buckles in the breach and buckle cam, this is another advantage of the present invention.Move to after the off-position Deng locking section, in case ejector can eject draw ring from compressing latch, the bolt button cam of this ejector can arrive at the position at locking section bolt button breach place at the same time, thereby stops this cam backward rotation.This declaration of will compresses latch and is not restricted in, so that the position around it can make the free end of this draw ring place the location under the situation that is not subjected to any interference.

This ejector is designed to a kind of spring-loaded pivoting lever, and the advantage that have this moment is really to make this ejector all the time abundant stroke can be arranged, and can definitely draw ring be drawn back from compressing latch when locking section is in the off-position.

From using viewpoint, preferably locking section is designed to a pivot sliding part that cooperates with combination lock.If correct dialling checked the number to the setting of unblanking required, oppositely the moving just this pivot sliding part can be released towards load on spring.Otherwise, if number dials to non-correct setting, just can prevent definitely that so this pivot sliding part from moving.

From saving viewpoint from damage, locking section is overlapped in when latched position and compresses on the latch, this another advantage of can saying so.It is not the zone of an overlapped part as prior art, but the whole free end of draw ring is overlapping in addition.

What deserves to be mentioned is that in addition the pivot sliding part has disposed a brake, it can be matched with the lock slide of lock.If stir number,, be not subjected to moving of any interference to cause the pivot sliding part that has brake just lock slide is removable to correct setting.Yet, the number of stirring to non-correct setting, this locking slide just can utilize brake and stop the pivot sliding part to move.

Because that end that the spring of pivot sliding part is exerted pressure to this sliding part also can be guided with a kind of linear fashion in the lock housings with the free end that causes this brake, so this spring has been brought into play dual-use function brake generation effect.Therefore, spring of the two needs of pivot sliding part and brake gets final product.Stir number to correct setting, then also stretchy brake under the situation when the pivot sliding part moves moves free end straight line in the lock shell of this brake.

In fact this ejector also has its advantage compressing the design that is overlapped between latch and the combination lock on the pivot sliding part.Because this kind design, during off-position after the pivot sliding part is in pivot, bolt button cam just can definitely snap in the bolt button breach of locking section.In addition, each assembly of relevant ccontaining lock, optimized utilization is also accomplished in the inside of lock shell.

If desire is fixed two draw rings of slide fastener, so also be suitable for the design that this is special and become and have two symmetrically arranged pivot sliding parts, and allow these sliding parts have corresponding with it latch and ejector of compressing separately.Each draw ring is furnished with a locking section separately.Draw ring just can in regular turn or be drawn back simultaneously when the time comes.In addition, also can only move a draw ring to its off-position.

Last advantage is if draw ring is placed the location, and when the pivot sliding part was pivoted to latched position, the bolt button just lost efficacy.Because actual triggering connecting rod is a draw ring itself, so must need to observe the order of locking.

Now in conjunction with the accompanying drawings the example of a scheme of the present invention is further described.Wherein:

Example shown at first seeing also, the lower semisection of suitcase 1 are provided with one in order to the fixing fixed mechanism 2 of two draw rings 3 of slide fastener 4.As shown in Figure 1, this slide fastener is pulled on, and 3 of the draw rings mechanism 2 that is fixed is fixed to the place that can't start suitcase 5 case lids.

Specifically, fixed mechanism 2 has a shell 6 and one with its casing cover that covers 7.The remaining component that a combination lock 8 and lock are then arranged between these two.

Side is the elongated envelope 6 of circular arc, and its longitudinal surface is provided with three upright latches 9, on the free end 9 of these latches ' insertion casing cover 7 in aperture and the corresponding shrinkage pool 10 of these latches.Be set with a digit wheel 11 and a locking plate 12 on each upright latch 9 in regular turn.In addition, on upright latch 9, also has a compression spring 13, one end of this spring is by the bottom 6 of shell 6 ' supported, the other end then can be exerted pressure to locking plate 12 towards the direction of digit wheel 11, and the inner surface that digit wheel 11 is faced with it by casing cover 7 is supported (seeing also Fig. 5).This digit wheel 11 is that profit is connected with each other via the braking hookup in a known manner with locking plate 12, so that when rotating digit wheel 11, locking plate 12 is and then rotation also.If the rotation of locking plate 12 is obstructed, digit wheel 11 is with respect to this locking plate 12, and is still rotatable and make this locking plate 12 avoid the strength of compression spring 13.Braking hookup between digit wheel 11 and the locking plate 12, belong to each other towards to can be provided with ten may application positions the sort of pattern.

Each locking plate 12 is provided with the V-notch 14 that can cooperate with a lock slide 16 some protuberances 15 for one along its periphery, and the shape of these protuberances can be corresponding with these breach.Lock slide 16 is being extended below the locking plate 12 and is being guided on three upright latches 9.16 of this lock slide in shell 6 bottoms 6 ' adjoiner, and correspondingly be provided with three slotted eyes 17.In addition, a facet of lock slide 16 forms a branch center latch 18, for inserting that end that supported by shell 6 with compression spring 19.

If the number of stirring to non-correct setting, this lock slide 16 has at least individual protuberance 15 to understand locked 12 periphery surface in conjunction with the pulling force of compression spring 19, and it is supported to as shown in Figure 2 position.These protuberances 15 stretch out the plane that surmounts lock slide 16.According to diagram, two protuberances 15 on the left side cooperate with brake 20.Respectively this brake 20 is that to stretch into section be the inside that U-shape lock is decided section 21.The leg side 22 of pointing to enclosure is provided with an aperture 23 that can supply the bearing journal 24 of ccontaining brake 20.These brakes 20 are designed to single pin formula bar handle with locking section 21.Each locking section 21 extends a latch 25, the shape of this latch be with shell 6 longitudinal surfaces on cooperate and can insert in it with the relative dead eye 26 of combination lock 8.So respectively this locking section 21 forms a pivot sliding part 28 that is almost rectangular shape, and according to diagram, bearing is located at the following outer corner of this pivot sliding part.

At each faceted position, shell 6 is provided with one from this lining that extends out 27.Respectively this lining 27 can for example be designed to a kind of torsionspring for a spring of ccontaining pivot sliding part 28.This short leg 28 ' be is supported by the facet of shell, otherwise should long leg 28 " then stretch into an aperture 29 of brake 20; again in conjunction with brake 20 after clockwise direction is to spring-loaded; promptly be supported in shell side on the web 30 of the tangential extension of lock slide moving direction, surmount bearing to cause it.Simultaneously, this pressure can be applied in to locking section 21 (pivot sliding part), and brake within it then is installed into the moving direction keeping parallelism with this lock slide, and overlaps the compressing on the latch 31 of shell side.These compress latch 31 is that extend at rear, there relative with combination lock 8 on shell 6 longitudinal surfaces, and this compresses the diameter of latch 31 diameters less than the set aperture 32 of draw ring 3 free ends.

At the position that compresses between latch 31 and the combination lock 8, below each pivot sliding part 21, be provided with an ejector 33.Respectively this ejector 33 is configured to the pivot rods of a spring-loaded.The outer end section 34 of hook-type can match with a uncinus 35 of shell side, so this outer end section 34 and uncinus 35 form the bearing of single arm type ejector 33.Near this bearing, there is individual ejector spring 36 to apply effect to each ejector 33, direction towards locking section 21 leg sides 22 and pivot sliding part, abutting end to ejector 33 is exerted pressure, the abutting end of these ejectors 33 is provided with the bolt of latch shape and buckles cam 37, so that cooperate running with the bolt button breach 38 of locking section 21.From the stop edge 39 that casing cover 7 extends out, then form the backstop of locking section 21.

The following stated is an operating mode of the present invention:

Fig. 1 and 2 be depicted as draw ring 3 be in latched position and cover in slide fastener 4 compress latch 31 situations.The number of combination lock 8 is not set to the position that can lock slide 16 is shifted simultaneously via locking plate 12.Therefore, the upper limb 15 of protuberance 15 ' position brake 20 stereognosis formula finger pieces 20 ' the path of dividing a word with a hyphen at the end of a line in.Sliding part 21 just can not move around its bearing because these stereognosis formula finger pieces 20 ' meeting to protuberance 15 upper limbs 15 ' generation effect of that side of lock slide, therefore pivots.

As desire fixed mechanism 2 is unblanked, then must as shown in Figure 3 number be toggled it to correct setting.So, allow 16 the V-arrangement protuberance 15 of breach 14 and lock slide of locking plate 12 align, then can move to other restriction site according to the strength of compression spring 19 because of the latter, add the upper limb 15 of protuberance 15 ' can be arranged on outside the stereognosis formula finger piece 20 ' path of dividing a word with a hyphen at the end of a line of brake 20, so that can utilize and stir digit wheel 11 and allow locking plate 12 rotations.

Now, the pivot sliding part 28 that constitutes locking section 21 just can be in regular turn or is jointly moved to position shown in dotted lines in Figure 6 around their bearing 25/26.When reaching this off-position, ejector spring 36 can make ejector 33 pivot, thereby can know from Fig. 7 and find out, when compressing latch 31 with draw ring 3 pull-ups from shell 6 is extended, ejector 33 will be pressed down by draw ring 3.When ejector 33 pivoted, their bolt button cam 37 promptly snapped in 38 li of the bolt button breach (consulting Fig. 6 and 7) of locking section 21.Therefore, locking section 21 can be remained on this off-position.When pivot sliding part 28 (locking section 21) is pivoted, stereognosis formula finger piece 20 ' promptly can move on a rough straight path in the lock shell scope, they are no longer supported by the web 30 of lock shell side, supported (seeing also Fig. 6) but change by lock slide 16 protuberance 15 corresponding with it.

If fixed mechanism desires to reach this latched position,, draw ring 3 needs to compress maintenance location on the latch 31 in correspondence just being provided with that end of opening 32.At the overlapping position of draw ring 3 free ends and ejector 33, draw ring 3 can be to latter's generation effect, make its antagonism spring pressure and towards outer casing bottom 6 ' direction pivot, discharge locking section 21 to cause bolt button cam 37, so that the spring-loaded reversion of carrying out limit by backstop 39 is moved.After all being placed in the location Deng two draw rings 3, just can be returned to original position as shown in Figure 3, wherein locking section 21 overlaps on the corresponding end section that compresses latch 31 and draw ring 3.If when having at least a digit wheel 11 to be rotated, just lock slide 6 can move to another extreme position as shown in Figure 2, wherein brake and stereognosis formula finger piece 20 ' the end be that the position is at the upper limb 15 ' turnover zone of lock slide 16 protuberances 15.Therefore locking section 21 just can not move to the off-position.

If desired number is reset, then must utilize digit wheel 11 before to set and present unspent number, make it reach position shown in Figure 3, wherein the protuberance 15 of lock slide 16 has snapped in the breach 14 of locking plate 12.At this moment ballpoint pen 41 nibs shown in dotted line can be passed the jack 40 of shell 6, till the corresponding facet that arrives at lock slide 16, the latter can no longer avoid spring pressure when the time comes, thereby locking plate 12 can be remained in the place that no longer is rotated.At this moment with respect to locking plate 12, digit wheel 11 can be rotated, so that through axially avoiding after the action, locking plate just can be via a braking hookup be connected with digit wheel in selected position.

All disclosed features are principal character of the present invention.When disclosing the application's case, disclosure relevant with it and the priority document (the pre-registration documents copy of novel patent) that inspection is attached is all listed in fully, lists in the claim of this registration for the feature that these files are contained.
