Definitions

  • the release may be eflected through the intermediary of a 0i ..70/69, 70, 71, 73, 79, 81, resilient member inefl'ectuany in the 2 2 830 condition ofthe latch.
  • My present invention relates to a closure device for suitcases, trunks or other containers having two separable parts, such as a base and a lid, adapted to be latched in a closed position from which they can be released by manual operation of an actuating element.
  • a keycontrolled locking mechanism is designed to prevent any untimely release.
  • An object of my present invention is to provide a closure device of this general type in which any jimmying of the lock becomes virtually impossible.
  • Another object of my invention is to provide a trunk closure or analogous device which can be released, in its unlocked condition, by the simple displacement of an actuating element (such as the aforementioned flap) also doubling as a complement of a housing wall to prevent the intrusion of dust and dirt and to give a pleasing overall appearance.
  • an actuating element such as the aforementioned flap
  • a more specific object of my invention is to provide an actuator of the aforedescribed type which automatically retains its depressed state as long as the closure device is released, returning to its normal position flush with the housing wall upon a relatching ofthe interacting elements.
  • a lever or slider forming part of a latching mechanism (and including detent means for engagement with a coacting tongue or the like as described above) is movable on the lock housing between an inoperative and an operative position, being held in the latter position by retaining means which may take the form of a biasing spring and/or of a separate spring-biased bolt thereon engageable with a catch in the housing.
  • a manually depressible, outwardly biased actuating element on the housing preferably in the form of a pivoted flap, is disposed at a location laterally offset from the insertion slot for the latching tongue and is provided with force-transmitting means for releasing the slidable or swingable latch means from its operative position upon inward depression of this element.
  • the closure device is provided with a lock to prevent any unauthorized or accidental opening of the container equipped therewith, operation of that lock will block the release of the latch means by the manual actuator. If this blocking effect is exerted directly upon the element displaceable by the actuator (i.e., upon the latch itself or upon a bolt carried thereon), a forcible depression of the actuator against the blocked element could damage the force-transmitting portion of the actuator unless, in accordance with another advantageous feature of my invention, this forcetransmitting portion is made resilient so as to yield ineffectually when the release mechanism is blocked.
  • the design of the actuator as a flap swingable about an axis proximal to the latching mechanism protects this mechanism against tampering from without by maintaining the actuator interposed between the finger of the user and the interior of the housing containing the lock.
  • FIG. I is a front view of a closure device embodying the invention.
  • FIG. 2 is a fragmentary sectional view of a suitcase provided with the device of FIG. I;
  • FIG. 3' is a longitudinal sectional view taken on the line III III of FIG. 1;
  • FIG. 4 is a view similar to FIG. 3, illustrating a modification
  • FIG. 5 is a front view, with parts broken away, of another embodiment of my improved'closure device
  • FIG. 6 is a side view of the device of FIG. 5;
  • FIG. 7 is a bottom view of the device of FIGS. 5 and 6, shown partly in section on line VII VII of FIG. 5;
  • FIG. 8 is a fragmentary sectional view of a latching lever forming part of the device of FIGS. 1 3;
  • FIG. 9 is a cross-sectional view taken on the line IX IX of FIG. 8;
  • FIG. 10 is a view similar to FIG. 9, showing a modification
  • FIG. 11 is a view similar to FIG. 10, taken on the line XI XI of FIG. 10;
  • FIG. 12 is a front elevational view of part of the device of FIGS. 1 3 in an alternate position.
  • FIGSQI 3 showing a closure device 6 for a suitcase partly illustrated in FIG. 2.
  • the suitcase includes a base portion 1 and a lid portion 2 whose confronting edges are reinforced by metallic frames designated 3 for the lid and 4 for the base.
  • the lower frame 4 includes a web 5 set back to form a channel for the front plate 8 of a housing 8 which constitutes one of the two relatively movable parts of device 6, the other of these parts being a locking element in the form of a tongue 7 which is riveted to lid 2 at 33 and whose lower end, formed with a rectangular aperture I2, extends into housing 8 through a slot 9 upon a lowering of lid 2 on the base I as illustrated in FIGS. 1 and 2.
  • Tabs 44 on front plate 8 are shown bent over in FIG. 2 to fasten the housing 8 to the web 5.
  • Front plate 8 is divided into a main portion, formed with a cutout 45, and a side portion, formed with an opening 46 in line with that cutout.
  • a lever I0 pivotable about a fulcrum 17 at the left-hand end of housing 8 as viewed in FIG. 3, is urged outwardly by a leaf spring 23 and can be pressed back into the cutout 45, against the spring force, so as to lie flush with the front plate 8'.
  • a projection II on lever I0 forms a detent for tongue 7 by engaging in the aperture 12 thereof when the lever is thus pressed home.
  • a bar 18 rigid with a pusher member or bolt 15 on the free right-hand end of that lever snaps into engagement with a slot 19 in a bracket 20 extending from the rear wall of housing 8.
  • Bolt 15 projects from a prismatic casing 37 integral with lever 10 and is spring-urged, as more fully described hereinafter with reference to FIG. 9, for inserting the tip of its bar I8 into the slot 19 when the lever 10 is swung in to latch the tongue 7 in place.
  • cutout 45 and opening 46 is marked by a pin 21 about which a flap 14, serving as an actuating element, is swingable in a clockwise sense into a space 13 of housing 8 as indicated by an arrow in FIG. 3.
  • Flap 14 is normally held in a position flush with front wall 8' by a resilient element 22 which forms one leg of a generally U-shaped spring 22 secured to the rear surface of the flap; the other leg I6 of that spring is a force-transmitting element bearing upon bolt I5 to dislodge the bar 18 from the slot I9 of bracket 20 when the flap I4 is thrust inwardly.
  • Such dislodgment releases the lever I0 from its latching position and allows the spring 23 to restore that lever to its swung-out position shown in FIG. 3, thereby freeing the tongue 7.
  • Lever 10 carries a lock 34 with a keyhole for the insertion of a key 43 or 143 (FIG. 9 or 10) to block the operation of the release mechanism just described.
  • Two types of blocking means are shown in FIGS. 8, 9 and I0, 11, respectively.
  • a slider 38 in casing 37 is integral with bolt 15 and bar 18 and is urged toward the right by a spring 39 interposed between the slider and the inner casing wall.
  • This slider overlies a locking slide 40 with two prongs 40, 40" straddling the bar 18 and with a pair of humps 47 engageable by the key 43 to displace the slide 40 between its blocking position and a nonblocking position to the left thereof.
  • the two positions are defined by a pair of notches 42 in slide 40 alternatelyengageable by a kink in a leaf spring 41.
  • prongs 40' and 40" pass through the slot 19 of bracket 20 so as to maintain the engagement between this bracket and lever 10 even when the bar 18 is withdrawn by leftward pressure upon bolt 15 from the spring leg I6 of FIG. 3.
  • Bolt 15 also has a slot 48 which receives the slightly inclined free end of bracket 20 with enough clearance, to allow unhindered displacement of the bolt within its operating range.
  • FIGS. 10 and 11 wherein elements corresponding to those of FIGS. 8 and 9 have been designated with the same numerals preceded by a I in the position of the hundreds digit, I have shown a modified latching mechanism with a locking slide 140 displaceable transversely to the direction of movement of the pusher-bar head or slider I38 rather than parallel thereto as in the preceding case.
  • Slide 140 indexable in either of two alternate positions by a leaf spring 141 engaging in notches 142, has a fin I40 coacting with a lug 138' on slider 138 in the illustrated blocking position in which the bar 118 cannot be retracted from the slot 119 of bracket 120. This is also the position illustrated in FIG.
  • FIG. 4 I have shown a modified housing 8a having a rearward extension 24 formed with a slot 9a; the detent Ila of lever 10a has been correspondingly lengthened to project into the housing extension 24.
  • This arrangement is particularly designed for larger suitcases and trunks, its operation being similar to that of the device of FIGS. 1 3.
  • FIGS. 5 7 I have illustrated a latch mechanism of a type described in my copending application U.S. Ser. No. 822,550 filed 7 May I969 (now abandoned).
  • the locking tongue 7b of this device entering the housing 8b through a slot 9b, has a camming formation 26 coacting with a similar formation 25 on a sliding latch Ib within the housing whereby this latch is moved to the left (FIGS. and 7), against the force of a spring 29, when the tongue enters the slot on closure of the suitcase or other containers equipped with that device.
  • Slider 10b is formed with an abutment b contacting a thrust plate 1612 on a preferably resilient arm 22b which extends from the rear surface of flap 14b, the latter being pivotable about a pin 21b so as to enter the space 13b of housing 18b upon being manually depressed.
  • Such displacement of actuator 14b shifts the sliding latch 10b to the left, beyond the limit of its displacement by the camming formations 25 and 26 as described above, whereby a lug 27 on latch 10b enters a hole 28 in housing 8b to index the latch in its inoperative position.
  • pivot 21 or 2112 of actuator 14 or 14b at the junction of the main and lateral housing portions, thus at a location proximal to the latch mechanism, protects this mechanism against tampering even upon inward deflection of the flap.
  • a suitable blocking mechanism controlled by a key inserted in lock 34b, is also contemplated for the system of FIGS. 5 7.
  • this mechanism may include a stud 35 on latch 10b engageable by a hook 36 which can be swung out of such engagement by rotation of the lock barrel with the key.
  • a closure device for a container having two separable parts meeting along a parting line in a closed position comprising:
  • a coacting member on the other of said parts having a locking formation positioned for insertion into said housing through said slot upon closure of said container;
  • latch means movable in said housing between an inoperative and an operative position, said latch means being provided with detent means engageable with said locking formation in said operative position for preventing separation of said parts, said housing having a front wall with a main portion overlaying said latch means and with an opening in a side portion adjoining said main portion;
  • a device as defined in claim I further comprising keycontrolled locking means for blocking the release of said latch means.
  • said force-transmitting means comprises a resilient extension of said flap and said latch means includes a coacting member blockable by said locking means and displaceable by said extension unless blocked.
  • said latch means comprises a spring-loaded member urged toward said operative position and indexing means for releasable maintaining' said spring-loaded member in said inoperative position, said force-transmitting means being positively engageable with said spring-loaded member for holding said flap depressed upon the indexing of said spring-loaded member in said inoperative position.
  • a closure device for a container having two separable parts meeting along a parting line in a closed position comprising:
  • an elongate housing on one of said parts adjacent and substantially parallel to said parting line said housing having a slot facing the other of said parts and further having a front wall provided with an elongate cutout;
  • a coacting member on the other of said parts having a locking formation positioned for insertion into said housing through said slot upon closure of said container;
  • a latch lever mounted in said cutoutfor swinging about a first pivotal axis between an operative position flush with said front wall and an inoperative position, said latch lever being provided with detent means engageable with said locking formation in said operative position for preventing separation of said parts;
  • said retaining means includes a catch in said housing and a spring-biased bolt on a free end of said lever engageable with said catch in said operative position, said flap being provided with an extension positioned to bear upon said bolt upon an inward swing of said flap for disengaging same from said catch.
  • a closure device for a container having two separable parts meeting along a parting line in a closed position comprising:
  • a coacting member on the other of said parts having a locking formation positioned for insertion into said housing through said slot upon closure of said container;
