Abstract

Abstract of the Disclosure A latching system for a luggage article in which an elongate latch console attaches interiorly to one section of the article for cooperation with a hasp assembly on another section of the article. The latch console includes a pair of left-hand latches which pivot in a counterclockwise direction from hasp-engaging to hasp-disengaging positions and a pair of right-hand latches which pivot in a clockwise direction from hasp-engaging to hasp-disengaging positions. Slide rods within the console are connected between the latches, and a central swiveling actuator moves the latches from their hasp-engaging to their hasp-disengaging positions responsive to movement from the actuator from a rest position. Springs return the latches, slide rods and actuator to their intial positions when the actuator is released. A combination lock is provided to lock the actuator in the rest position and the latches are mounted for movement independently of the slide rods when the hasps are disengaged to allow the hasps to be re-engaged with the latches even when the actuator is locked.

Description

33~

Th.is is a division of Can~dian patent application Serial No. 3~6,838 filed September 28th, 1981, Back&round of ~he Invention Tlle invention relates to latching systems suitable for use on luggage articles, for example for releasably securing a body section of an article to a hinged lid and the like. The invention is particularly adapted for use on luggage of the soft-sided type in which the front walls of the respective body and lid sections, to which the latching system i5 fitted, are of a somewhat flexible nature. However, the invention may also be used in other applications.
Latching systems for use on luggage articles should fulfill a number of basic requirements. First and foremost, they must provide secure latching of the body section of the article to the lid. In this regard, it is common practice to provide at least two individual latching assemblies spaced along the front walls of the respective sections. Further, it is desirable for the individual assemblies to be operable in a simple manner.
To this end, it is known to provide a common manual actua~or for operating a number of latch devices in unison by means of linkage and drive arrangements connected between the actuator and the respective assem~lies.
Additionally, it may be desirable to provide some form of locking means for the latching system, for securing against unauthorized opening of the luggage article.

,~, ~.~8~3~

Other desirable characteristics for luggage-latching systems are, for example, that the system should be as compact as possible, 80 as not to intrude unduly into the interior o the luggage article, that it should be relatively economical to manufacture and simple to fit and that it should be capable, to a degree, of accommodating misalignments which may develop between parts of the sections being latched. The last of these charact2ristics is of particular relevanc~ in systems intended for use on articles of the sof~-sided type.
The present invention is intended to provide a latching system for a luggage article which, to the extent possible, incorporates a combination of the desired charac-teristics in a novel form of latching structure.

Summary of the Invention The concepts of the invention may conveniently be applied in a latching system having a number of spaced latches housed in a relatively flat elongate console arrangement for attachment to one section of a luggage article, the latches being adapted to engage fixed hasps attached to another section of the article.

The present invention in one aspect provides a combination lock comprising a plurality of dial-driven sleeves mounted in axially abutting relation on a shaft ~or controlling a locking member dependent on the rotational position of the sleeves, the sleeves normally being coupled to the respective dials, and means for enabling the combination of the lock to be changed by uncoupling the sleeves-from the dials, said means in-cluding a shift lever positioned adjacent an end one of the sleeves for moving the sleeves axially to uncouple them from the dials by movement of the shift lever in one axial direction, the shift lever having an actuating portion at one end by which the shift lever can be moved manually, the actuating portion being adapted to project through an opening in a faceplate of the lock adjacent further openings in the faceplate through which portions of the respective dials project, and the shift lever further having a follower at its opposite end received in a guide opening provided in a baseplate of the lock, the guide opening allowing the shift lever to be tilted when the sleeves are uncoupled from the dials and holding the shift lever, when tilted, against movement in the opposite axial direction, 33~

In a preferred form of the invention the shift lever includes a blocking portion adapted to cooperate with the locking member for preventing the shift lever from being moved in said one axial direction to move the sleeves out of engagement with the dials except when the locking member is in an unlocked condition.
In a further ~orm of the invention in the tilted position of the shift lever, the blocking portion holds the locking member in the unlocked condition.
In a still further form of the invention the shift lever is mounted on the shaft.
Other aspects of the invention will be apparent from the following description and claims taken in conjunction wlth the attached drawings.

Description of Preferred Embodiment Referring initially to Figure 1, the invention is illustrated as embodied in a latching system for a luggage article such as a soft-sided suitcase or the like.
The case may, for example, have a body section with a somewhat flexible wooden front wall, part of the upper 15 , portion of which is shown in phantom at reference lO, and a hinged lid with a similar front wall, part of the lower portion of which is shown in phantom at reference 12.
The la~ching system includes a relatively 1At elongate latch console 14 for attachement interiorly to wall portion lO, a combined lock and actuator assembly 16 exposed on the exterior of wall portion lO and a relatively flat elongate hasp assembïy 18 for attachment interiorly to wall portion 12.
Latch console 14, illustrated in deta l in Figures 1 5, includes a channel-shaped base pla~e 20;
two left-hand latch assemblies 22A, 22B; two right-hand latch assemblies 24A, 24B; interfitting slide rods 26 33~

and 28 forming drive means for opera~ing the left-hand latch assemblies; similar interfitting slide rods 30 and 32 forming drive means for operating the right-hand latch assemblies; top plate 34, and end covers 36.
Each of the latch assemblies is made up of identical omp~nents, notably a latch holder 38, a pivotal latch 40, a latch spring 42, a hasp ejector 44, and an ejector spring 46. Holders 38 are of generally rectangular shallow box-like form having a depth substantially corre-sponding to the depth of base plate 20 and the holders fit in the base plate, being located by suitably spaced cutouts 48 in one upright wall of the base plate. Pro-jections 50 on the sides of each holder fix the holder in position laterally of ~he base plate, with an upper portion of ~he holder protruding therefrom. Base plate 20 may, for example, be an extrusion of a metal, such as aluminum, and the holders may be plastic moldings.
Holders 3$ each have a rear wall 52 ~see Figures 3 and 4), a base wall 54, and side walls 56, and each holder is formed symmetrically about a center line Pxtending transversely of base plate 20. On each side of the center line, the holder has a circular latch-receivin~ opening 58 in rear wall 52, and an ejector mounting plug 60. Side walls 56 each terminate in a head portion 62 providing ejector stop shoulders 64 and inclined hasp lead-in surfaces 66. At their lower ends, side walls 56 each have a locat-ing projection 68 for latch spring 42. Rear wall 52 3~

terminates at the bases of plugs 60 and side walls 56 have notches 70 (see Figure 1) so that a transversely extending open channel or slot is formed at the base of the holder for receiving part of one of the slide rods 26-32, as will be described.
The latches 40 may be identic~l plastic moldings~
each in the form of a crank having a notched latching por~ion 72 and an actuating portion 74. Between portions 72 and 74 the latch has a mounting section with bosses 76 and 78 on its opposite surfaces so that, by reversal of the latch, it may be pivotally mounted in either of the holder openings 58 by way of the respective bosses.
On the actuating portion 74, the latch has a locating projection 80 for the latch spring.
Hasp ejectors 44 comprise yoke-like members adapted to fit over the respective plugs 60 with springs 46 interposed therebetween, so ~hat the ejectors are urged ~oward shoulders 64. The ejectors have projecting hasp-engaging tongues 82 (see Figures 3 and 4).
In the left-hand latch assemblies 22A, 22B, latches 40 are moun~ed in holders 38 in the right-hand openings 58 for counterclockwise pivoting movement from the hasp-engaging positions (shown in Figure 2) to the hasp-disengaging positions. The ejec~ors in ~hese assemblies are fitted on the right-hand plugs 60 and hasp springs 42 are fitted between the latches and the right-hand projections 68 so as to bias the latches toward their hasp-engaging positions.

~ 3~7 In the right-hand latch assemblies 24A, 24B, on the other hand, latches 40 are reversed and mounted in holders 38 in the left-hand openings 58 ~or clockwise pivoting movement from the hasp-engaging positions ~Figures

2 and 3) to the hasp-disengaging positions (Figure 4).
The ejectors in the right-hand assemblies are fi~ted on the left-hand plugs 60 and the hasp springs are located correspondingly.
Slide rod 26 has at its right end an up-turned projection 84 providing a transverse tab 86. Towards its left end, rod 26 has a further up-turned projection 88 providing a transverse tab 90, the length and con-figuration of the rod being such tha~ projection 88 fits in the open channel of latch holder 38 of latch assembly 22A with tab 90 constituting a latch-engaging element engaging the actua~ing portion 74 of latch 40, as shown in Figure 2. At its left end, rod 26 has a T-shaped coupling element 92 coupled with a complementary cutout at the right end of rod 28. Rod 28 terminates in an upstanding transverse tab 96 fitting in the open channel of holder 38 of latch assembly 22B and constituting a further latch-engaging element engaging the actuating portion o latch 40. Rod 28 has upstanding side walls 98 fitting between assemblies 22A and 22B and limiting longitudinal movement of rods 26 and 28.
Slide rod 30 has at its left end an upstanding projection 100 providing a transverse tab 102 and towards _9_ 33;37 its right end a further upstanding projection 104 pro-viding a transverse tab 106. Projection 104 fits in the open channel of holder 38 of latch assembly 24A wi~h ~ab 106 constituting a latch-engaging element engaging behind the actuating portio~ of latch 40. At its right end, rod 30 has a T shaped coupling element 108 coupled to a corresponding cutout in the left end of rod 32.
Rod 32 at its right end has an upstanding transverse tab 112 fitting in the open channel of holder 38 of latch assembly 24B and orming a latch-engaging element engaging behind the actuating portion of latch 40. Rod 32 has upstanding side walls 114 fitting between latch assemblies 24A and 24B and limiting the longitudinal movement of rods 30 and 32.
Top plate 34 has depending side walls 35 (Figures 1 and 10) which interfit with the upstanding side walls-of base plate 20 and the plates have corresponding op~n-ings whereby they are assembled together with suitable attachment means (not shown). Additionally, the top plate has a central rectangular opening 37 to accept the casing of the lock and actuator assembly 16 and cutouts 39 may be provided in the top plate, if required, to fit the terminal portions of a central carrying handle of the luggage article. The latch console may conveniently be supplied to a luggage manufacturer in a fully assembled state for direct attachment to the interior of the relevant wall section of a luggage article, with the lock

3~7 and actuator assem~ly fitting into place from the exterior of the article. (The wall section of the article will have an opening corresponding to opening 37.) The end covers 36~ which may be plastic moldings, fi~ in opposite ends of base plate 20 and may be secured by any suitable attachment means.
Hasp assembly 18 includes an elongate channel 41 and four identical reversible hasps 43 having notched portions complementary to the latch portions of latches 40. The hasps may also be plastic moldings. Channel 41 has cutouts 47 (Figure 1) spaced to conform to the spacing of latches 40. The hasps are fastened in channels 41 by suitable fastening means and the two lef~-hand hasps are reversed with respect to the two right-hand hasps to complement the operation of the respective latches. End caps, as 45, are provided for the ends of channel 41.
When the hasps are in engagement with the respective latches, i.e., the luggage article is closed, the hasps depress ejectors 44 by engagement with tongues 82 as shown in ~igure 2.
Tabs 86 and 102 of rods 26 and 30, respectively, engage a central camming member 116 connected to a swiveling actuator 118, the actuator and camming member forming part of assembly 16. Camming member 116 is attached to actuator 118 by fastening means, such as screws 120 (see Figures 6 and 7) received in depending actua~or posts 122. The camming member has opposed downwardly extending tangs 124, 126 behind which 33'7 tabs 86 and 102 engage (see Figures 2 and 6). Thus, when the camming member 116 is swiveled counterclockwise, by swiveling movement of the actuator from the rest position shown in Figures 2 and 6, rods 26 and 28 are drawn to the righ~ while rods 30 and 32 are drawn to the left. The camming member thus constîtu~es a drive member for the slide rods and the tabs 86 and 102 form drive formations by which the rods are moved.
Movement of rods 26 and 28 to the right causes tabs 90 ~nd 96 to effect counterclockwise pivo~ing move-ment of the le~t-hand latches 40 against the action of latch springs 42, while movement of rods 30 and 32 to ~he left causes tabs 106 and 112 to effect counterclock-wise pivoting movement of the right-hand latches. The latches are ~hus moved from their hasp-engaging positions to their hasp-disengaging positions responsive to swiveling movement o the actuator from the rest position. Figure 4 shows right-hand latch assembly 24B in the hasp-disengaging position and it will be seen that the right-hand plug 60 and head portion 62 provide stop surfaces for the latch.
Further, release of the latches from ~he hasps causes ~he ejectors to urge the hasps outwardly with respect to the holders (Figure 4) thereby facilitating opening of the luggage article.
When actuator 118 is released, the latch springs 42 act as biasing means which return the latches to their respective hasp-engaging positions and, through tabs 90 ~ 3~7 96, 106 and 112 return the slide rods to their initial positions. Tabs 86 and 102 acting on tangs 124 and 126 return the camming member 116 and the actuator 118 to the rest position.
It will be appreciated, as seen particularly in Figure 3, that when the hasps are disengaged, the latches can be pivoted against springs 42 away from ~heir hasp-engaging positlons independently of the slide rods.
Thus, downward pressure exerted on inclined surfaces 72a of the illus~rated latch by the inclined hasp surface 41a produces a camming action, pivoting the latch away from the hasp-engaging position and allowing the hasp to be re-engaged without having to move the actuator and slide rods from their rest positions. When the surface 41a clears surface 72a, the latch is snapped back into hasp engagement by spring 42. The design of the hasps and latches and the specific angles of the respective camming surfaces (preferably about 45 in each case~ facilitates closing of the case even if there are slight misalignments between the respective hasps and latches.
Actuator and lock assembly 16 includes a body member 140 which, as previously indicated, fits in opening 37 in the top plate of the latch console, through a corresponding opening in wall 10 of the lugga~e article ~see Figure 7~. Body member 140 includes depending posts 142 by which it may be attached to base plate 20, by screws 144, or other suitable fastening means may be used. The body member further includes an opening 146 in which actua~.or 118 is rotatably mounted and the body member also forms part of a housing for a combination lock 130. Opening 146 includes a cross member 148 straddled by actuator posts 122, thereby limiting swiveling movement of the actuator, and the camming mem~er 116 prevents the actuator from being withdrawn upwardly from opening 146.
When fitting the latch console and assembly 16 to a luggage article, for example, the latch console may be attached to the interior of the relevant wall section of the article and assembly 16 may then simply be fitted into place from the exterior of the article through opening 37, the slide rods and camming member being suitably adjusted such ~hat tabs 86 and 102 interfit behind the tangs 124 and 126. Assembly 16 may then be fixed in place by the aforementioned screws 120 or the like.
Combination lock 130 ~see particularly Figures 7-14) is adapted to releasably lock the actuator 118 and ca~ming member 116 in the rest position, so that when the luggage article is closed, the latches cannot be disengaged from the hasps unless the lock is released.
Lock 130 is of the type in which dial-driven cams con~rol the movement of a movable locking member, in the form of a pivotal bolt 132, between locking and unlocking positions.
In the locking position, the bolt blocks movement of camming member 116, as will be described, and in the unlocking position it releases the ca~ning member for operation by the actuator. Lock 130 may conveniently be of a similar type to locks described in u.S. Patent No. 4,308~731 granted January 5, 1982 to Remingto~, and commonly assigned herewith.
Lock 130 includes a shaft 148 supported at its opposite ends between suitably shaped surfaces of body member 140 and a dished cover plate 150 suitably secured by screws, rivets or the like to the body member. Com-bination sleeves 152, 154, 156 are rotatably mounted on shaft 148 be~ween a coil spring 158 and an integral shaft collar 160. On ~he other side of collar 160 the shaft carries a shift lever 162, and spring 158 engages a washer 164 to urge the assembly o~ shaft, sleeves and shift lever to the lef~, as shown in the drawings.
Sleeves 152-156 carry encircling combination dials 166, 168, 170 and the sleeves have enlarged end flanges 172, 174, 176 constituting cams for the lock bolt, as will be described. The periphery of each cam is circular except for a substantially V-shaped notch 178, as shown in Figure 14. The sleeves are coupled for ro-tation to the respective dials in conventional manner by teeth 180 on the sleeves which mesh with corresponding openings 182 in the dials. The dials have conventional 33~
circumferentially disposed indicia, with portions of the dials protruding through suitable slots in a portion 138 of body member 140 constituting the lock faceplate, for manual rotation of ~he dials and sleeves. A dial spring 184 on the base of cover plate 150 has arms 186 ~Figure 10) engaging detents between the respective dial indicia, so that the dials are rotated in equal increments between successive indicium-displaying positions.
The lock bolt 132 has projecting tongues 188 by which the bolt is pivotally mountel in suitable openings (no~ shown) in cover plate l'iO. Openings 190, 192, 194 in ~he bolt (see Figure 12) accommodate the respective dials and the bolt has cross-bars 196, 198, 200 positioned to engage against the peripheries of cams 172-176, respectively. The bolt is urged upwardly into engagement wi~h the cam peripheries by coil springs 202, 204 (see Figures 6 and 10).
As seen particularly in Figures 10 and 12, cross-bars 196-200 of the bolt are shaped to provide ridge portions 206, 208, 210, having converging planar surfaces. When all the sleeves 152-156 are ro~ated into a particular alignment, as shown in Figure lO, correspond-ing to particular indicium-displaying positions of the respective dials (i.e., the on-combination setting of the lock), the ridge portions engage in the resp~ctive ~am no~ches 178 and the bolt assumes an upper unlocked condition under the influence of springs 202, 204. ~hen, ~1~9337 however, any one or more of the dials is rotated by one or more increments from the aligned position, to move the lock off-combination, a camming action is effected between the respective notch and ridge portion whereby the bolt i5 moved down against springs 202, 204 into a locked position in which the relevant ridge portion is disengaged from the respective notch and brought into tangential contact with the dial periphery.
Specific design requirements for the notches and ridge portions and the advantages ob~ained with this type of construction are referred to in greater detail in the copending application referred to above.
Bolt 132 includes an elongate extension arm 206 extending through a suitable vertical slot Snot shown) in cover plate 150 and terminating in a depending tab 208 adapted to cooperate with a corresponding ~ab projection 210 on camming member 116 (see Figures 6 and 9). When ~he bolt 132 is in its loweredJ locked position, tab 208 engages behind projection 210 and prevents member 116 from being rotated by actuator 118 to operate the latching system. When, however, the bol~ 132 assumes its upper unlocked position (the lock having been set on-combination) tab 208 clears projection 210 as seen in Figure 9, and camming member 116 is freed for rotation by the actuator to o~erate the latching system.
Lock 130 further includes means for changing the set combination by moving the dials out of engagement with the respective sleeves and allowing the dials to be rotated relative to the sleeves. To this end, when the lock is set on-combination, shaft 148 and sleeves 152-156 ean be moved to ~he righ~ against spring 158 by means of shift lever 162, rom the Figure 7 position into a combination-changing position shown in Figure 11, thereby uncoupling the sleeves from the dials.
Shift lever 162 includes a manual actuating portion 2].2 projecting through an opening 214 in the lock faceplate, a body portion 216 abutting shaft collar 160, a blocking portion 218 and a follower 220. When the lock bolt 132 is in its lowered, locked position, blocking portion 218 is in blocking alignment with cross member 222 of the bolt (Figure 7A~ thereby preventing the shift lever from being moved to the right. When the lock is set on-combination, however, and the bolt is lifted, cross member 222 clears blocking portion 218 (Figure 7) and allows the manual actuating portion 212 of the shift lever to be moved to the right in opening 214. This move-ment causes the assembly of shaf~ 148 and sleeves 152-156 to be moved into the Figure 11 position against spring 158.
Movement of the shift lever 162 to the right causes follower 220 to move along one leg 224 of an L-shaped opening 226 in cover pla~e 150 (see Figure 8).
In the Figure 11 position, the shift lever can then be tilted on shaft 148 so that the follower 220 engages the other leg 228 of opening 226 behind a stop shoulder 230.

The shift lever can then be released and the stop shoulder holds the shaft and sleeves in the combination-changing position. Further, in the combination-changing position, blocking portion 218 of the shift lever engages under cross member 222 of the bolt as seen in Figure 11. This holds the bolt in ~he upper unlocked ~osition, thereby precluding rotation of the sleeves and avoiding a loss of com~ination.
When the combination has been changed, shift lever 162 can be tilted back into its ini~ial orientation on shaft 148 to bring follower 220 out of engagement with shoulder 230. Release of the shift lever ~hen allows sprin~ 158 ~o retu~n the shaft, sleeves and shift lever to the Figure 7 position, thereby re-coupling ~he dials lS and sleeves and se~ting the new combina~ion.
It will be seen from the foregoing that the invention provides a latching system suitable for a luggage article, which is simple to mount, by attaching the latching console and hasp assembly to ~h~ interior of the respective wall sections and securing the lock and actuator assembly in place on the exterior of the article.
The system uses a single central actuator for operating a series of latches in unison and can be readily locked and unlocked by means of a central lock operatively con-nected with the actuator. Since the latches can be moved independen~ly of the actuator, the luggage article can be closed even when the actuator is locked. Further~

~ 3~ ~

since both the left-hand and right-hand latch assemblies are constituted by identical components, the system lends itself to economies in manufacture.
While only a single preferred embodiment of the invention has been described herein in detail, the invention is not limited thereby and modifications can be made wi~hin the scope of the attached claims. For example, different locking arrangements may be used in place of the described combination lock for locking the actuato.-r in the rest position.
