The present invention relates to a closure device assembly for a piece of luggage, in particular a suitcase, and to a suitcase with such a closure device assembly.
It is known to lock pullers of a zipper in a lock as shown in US 2011/0186397 A1. The zipper pullers, i.e the pull tabs, are engaged in dedicated slots in the lock. The slots are arranged spaced to one another in the direction of the zipper. Such locks have the drawback that a puller may be inserted in the wrong slot, whereupon the lock must be opened for placing the zipper puller correctly. Also, the locked puller may rather easily be broken to remove them from the slider, whereupon the slider is free to open the zipper. Moreover, the lock is easily accessible for manipulation and therefore not as secure as desirable.
Finally, in case of a suitcase with hard shells, the closed zipper is a further weak spot which may be opened by means of a tool as simple as a pen.
One of the objects addressed by the present invention is to provide an improved closure device assembly as mentioned in the preamble of claim 1.
This object is achieved by the closure device assembly of claim 1. Accordingly, a closure device assembly for a piece of luggage, preferably a suitcase, most preferably a hard shell suitcase, is suggested. The suitcase may be a frameless hard shell suitcase. The piece of luggage has a first body portion, a second body portion, and a zipper, said zipper being arranged between said first and second body portions. Furthermore, the closure device assembly comprises:
at least one engagement element adapted for arrangement on said first body portion;
at least one buckle element adapted for arrangement on said second body portion, said buckle element being adapted for pivotal motion between an open position and an engagement position such that, in said engagement position, said buckle element is in contact, preferably in engagement, with said engagement element, said pivotal motion being about an axis that extends substantially parallel to said zipper, and
at least one zipper slider adapted for operation of said zipper and having at least one engagement section for engagement with said engagement element and/or said buckle element.
Moreover, the closure device assembly comprises a locking device for locking said engagement section of said zipper slider, when said zipper slider is in a closed position.
In order to achieve the above object, said buckle element further comprises a cover element and is adapted to cover in a closed positon of the closure device assembly with said cover element at least part of the locking device and a part of the zipper slider, preferably said engagement section of the zipper slider in said closed position.
Preferably, only a part of the zipper slider is covered by the cover element in closed position.
Preferably, the zipper puller itself is not directly engaged with said engagement element and/or said buckle element, only via the slider. Accordingly, the engagement section is not part of the zipper puller but part of the slider. The term “slider” has to be understood as the element that brings the zipper parts into and out of engagement, while the puller is the tab that is attached to the slider for easy manual operation of the zipper.
The present invention is based on the insight that the closure device assembly may be equipped with a buckle element that covers, with its cover element, the sensitive parts of the closure device assembly. Thereby the security of the closure device assembly is increased and the locking device and the engagement section of the zipper are protected from third-party access. Moreover, in case of hard shell luggage pieces the closure device assembly keeps the hard shell body portions together, even if the closed zipper is broken. Accordingly, in particular for hard shell luggage pieces, the closure device assembly provides further security.
Preferably, the assembly is designed to allow for engaging the sliders after closing the buckle element.
Preferably, the assembly is designed to allow opening the zipper without opening the buckle element.
Preferably, the engagement section is insertable into the closure device assembly in the direction of the zipper.
In some embodiments, the engagement section may be integral part of the zipper slider. The engagement section and the slider may therefore be single-piece element. Here, the engagement section has to be distinguished from the zipper puller of a conventional zipper, the puller being hinged to the slider. The engagement of the slider itself and not of the puller provides additional security as the connection between the slider and the puller is a weak link. In the context of these embodiments the slider is inserted into the closure device for engagement there with at least its engagement section, preferably in the direction of the zipper.
In some embodiments, the engagement section may be attached to the zipper slider, e.g. it may be the zipper puller or another part attached to the zipper slider.
In some embodiments, the locking device further comprises at least one bolt adapted for releasably locking said zipper slider and a bolt biasing member being attached to and biasing said bolt, wherein said bolt is moveable between
wherein said buckle element is adapted to cover, in said engagement position, with said cover element at least said bolt and said engagement section of the zipper slider in said closed position.
The term “body portion” refers to a part of the piece of luggage, preferably to a half-shell of a suitcase.
The term “zipper slider being adapted for operation of said zipper” means that the zipper slider may be brought into engagement with rows of teeth arranged along at least parts of an edge of the body portion. The tooth elements may then be made to interdigitate for linking the rows, whereby the opening between the body portions is closed.
The term “the pivotal movement being about an axis that extends substantially parallel to the zipper” means that the buckle element is arranged on the first body portion such that its pivot axis extends substantially parallel to the tooth rows of the zipper. Accordingly, the buckle element is pivotable to extend over the zipper to contact the engagement element arranged on the second body portion, whereas the first and second body portions are spaced from one another over said zipper.
The term “adapted for arrangement on a body portion” means that the buckle element and the engagement element are designed to be arranged on the respective body portion such that the zipper slider may be locked in the closed position by means of the bolt, wherein said bolt and at least the engagement section of the zipper engaging with the bolt may be covered by the buckle element. This may be done by bolting, gluing, screwing, or integrally forming them into the body portions.
The term “closed position” is the position of the zipper slider where it can be locked by the locking device, i.e. where it extends into a designated gap of the closure device assembly. Typically, this is the position where the zipper ends. With reference to the closure device assembly, the term “closed” refers to the closed state of the assembly.
The term “engagement position” is the position of the buckle element where it contacts the engagement element. Preferably, the buckle element engages in a hook-connection with the engagement element.
The term “open position” refers to the position in which the buckle element is not in contact with the engagement element. In this position, the zipper slider is preferably not locked and may be freely moved along the zipper for opening/closing the piece of luggage.
The term “bolt being adapted for releasably locking said zipper slider” means that the bolt, when in locking position, mechanically blocks the movement of the zipper slider. Preferably, the bolt extends and moves angular or rectangular to the direction of the zipper and may extend into a recess, a lug, a ring, or a loop of the zipper slider. Preferably, the bolt may be moved from the locking position into the release position whereby the engagement of the bolt into the engagement section of the zipper slider is lifted.
The term “adapted to cover, in said engagement position, at least part of the locking device and said engagement section of the zipper slider in said closed position” means that the buckle element covers with a preferably plate-like cover element the sensitive region where the engagement section is locked by the locking device, whereby unauthorized access to the locking device is prevented. Said part of the locking device that may be covered may, in some embodiment, be the bolt that catches the zipper slider.
In some embodiments, said bolt biasing member biases said bolt in said release position. This ensures that the closure device assembly only locks when the bolt biasing member is activated, e.g. if said buckle element is in contact with said engagement element, wherein the engagement element has means for activating the bolt biasing member. Accordingly, this feature helps to prevent faulty operation of the closure device assembly.
In other embodiments, said bolt and said bolt biasing member are attached to said buckle element.
In some preferred embodiments, said bolt and said bolt biasing member are attached to said engagement element. This design has the advantage that said buckle element that is moved a lot is rather light and said bolt, being arranged on said engagement element, is always properly oriented with respect to the zipper slider when in closed position.
In some embodiments, said bolt is arranged on a pivotable bolt lever arm, preferably a single-lever arm, wherein said bolt biasing member biases said bolt lever arm in the release position. This allows a compact and mechanically stable construction of the closure device assembly.
In some embodiments, the closure device assembly further comprises an actuation device, wherein said actuation device is adapted for moving said bolt against said bolt biasing member from said release position into said locking position upon closing the closure device assembly, i.e. when the buckle element is brought into contact with the engagement element.
It is preferred to arrange the actuation device either on said engagement element or said buckle element, whichever does not carry the bolt. In some preferred embodiments, said actuation device is attached to said buckle element. The actuation device may be designed for actuation the bolt biasing member, i.e. for shifting the bolt lever arm from the release position into the locking position, upon closing the buckle element, i.e. when the buckle element contacts the engagement element.
In some embodiment, the actuation device is a latch element, arranged in the buckle element such as to be shiftable between the initial and the actuation position. The latch element may be moved by a push element and biased by a biasing member biasing the locking device.
In some embodiments, said actuation device comprises an own actuation biasing member for biasing said actuation device in an actuation position such that, upon closing the closure device assembly, said actuation biasing member overrides said bolt biasing member and pushes said bolt from said default release position into said locking position. Moreover, said actuation device may be adapted for being moved, preferably pivoted, against said actuation biasing member from said actuation position to an initial position. This motion is preferably controlled by a push element which has a lock. This also allows for releasing the locked zipper sliders without fully opening the closure device assembly.
Accordingly, the actuation position is the default position of the actuation device into which it is forced by its actuation biasing member. The actuation device may be brought into the initial position by e.g. pivoting the actuation lever arm against the action of the actuation biasing member, e.g. by means of the push element.
In some embodiments, said buckle element has a first engagement portion and said engagement element has a second engagement portion, the first and second engagement portions being adapted for mutual engagement. The engagement is preferably a positive-lock engagement like a hook-hook connection.
In some preferred embodiments, said buckle element is designed as a toggle clamp adapted for clamping the engagement element and therefore said first and second body portions to one another. The toggle-clamp design may comprise at least or exactly two pivot axis. Preferably, a double hinge lever is used to connect a base element which is on the body portion and the cover element to one another.
The first engagement portion may have a bent, hook-like edge region adapted for encompassing an edge of the engagement element. It may comprise an engagement web.
Preferably, the cover element of the buckle element is a plate-like element with inwardly facing rims that extend from the plate towards the piece of luggage such that the buckle element forms a covered space for installation of further parts of the closure device assembly such as, e.g., the actuation device. The rims or side walls may have recesses where the push element, the zipper and/or the engagement section(s) of the zipper slider(s) extend into the gap.
In some embodiments, the closure device assembly further comprises the push element for moving said bolt from said locking position into said release position. Accordingly, the push element may be pushed by the user while the closure device assembly is closed and the zipper slider(s) are locked. Upon pushing the push element the zipper slider(s) may be released and the slider(s) may be moved to open the piece of luggage.
In some embodiments, said push element is a push button arranged on said buckle element. Thereby the push button is well accessible by the user. Said push button is preferably arranged on the cover element opposite said first engagement portion, wherein the closed closure device assembly is adapted for moving said actuation device from said actuation position into said initial position by means of pushing the push element, whereupon said locking device is moved into the release position. In some embodiments, the bolt is moved thereby from said locking position into said release position.
Preferably, the push element is adapted to push, upon pushing on the push element, onto the bolt lever arm to bring it into release position. Accordingly, by means of the push element, the closure device assembly in closed position is adapted to bring locking device into release position without moving the cover element. The moving bolt lever arm may further be adapted to push then onto said actuation device for bringing the locking device into release position and the actuation device into initial position.
In some embodiments, the push element may be locked by a lock, e.g. a number lock, a key lock, or the like. Furthermore, a Transportation Security Administration (TSA) lock may be provided in some embodiments.
In some embodiments, said bolt and/or said engagement section of the zipper slider are/is formed, preferably provided with a slanted surface, such that the zipper slider that is moved to close the piece of luggage pushes said bolt, preferably against said actuation biasing member, into said release position. Accordingly, the buckle element may, when arranged on the piece of luggage, be closed before the zipper sliders are moved to closed position. For example, the piece of luggage may be filled with items; then, the body portions may be pivoted to one another. If the content of the piece of luggage is abundant, the user may have to press the body portions toward one another. The preferred embodiment with the toggle-clamp design then allows engaging the buckle element and the engagement element such that the position of the two body portions is secured. In a next step, the zipper may be closed with both hands, if necessary, and then the buckle element may be completely closed, i.e. the buckle element may be pivoted along the toggle motion to come into parallel arrangement with the surface of the piece of luggage, or vice-versa. If the toggle-clamp is closed before the zipper slider is in closing position, the zipper slider may simply be pushed into a gap under the buckle element such that it presses on the slanted surface of the bolt, whereby the bolt is moved out of the locking position into the release position and the engagement section may be fully inserted into the gap. The bolt is then forced back into locking position by the actuation device. Accordingly, the toggle-clamp design helps to close the piece of luggage step wise and with leverage as the toggle-clamp design allows for addition leverage upon closing the closure device assembly.
If the bolt and the bolt biasing means are arranged in the engagement element, the zipper slider can (but doesn't have to be) locked before the toggle-clamp designed buckle element is closed. It is, however, preferred that the default position of the locking device is the release position.
In some embodiments, the closure device assembly comprises at least or exactly two zipper sliders working in opposite directions on said zipper, wherein, preferably, the closure device assembly comprises at least or exactly one bolt for each zipper slider. Then the zipper sliders may be brought into closed position from different directions of the zipper.
In a preferred embodiment, the locking device and the actuation device each comprise two single-lever arms. The two lever arms of the locking device being preferably hinged to the same bolt lever pivot joint, and the two lever arms of the actuation device being preferably hinged to the same actuation lever pivot joint. This allows a compact and reliable use of the device.
In another preferred embodiment, the actuation device is a latch element that may be moved in the buckle element. In some embodiments, the latch element may be a single-piece element. In some embodiments, the latch element may have a contact portion for contacting the security device, preferably the two two-arm levers.
In some embodiment the latch element may be arranged and configured to be in contact with the push element, if any, such that a push action onto the push element translates to a movement of the security device from a locking position into a release position. The push element in actuation position may be moved back into its initial position through at least one biasing member. This biasing member may be the biasing member of the security device and/or a biasing member of the push element itself.
In some embodiments, the closure device further comprises a counter plate with at least one, preferably two support portions, wherein the counter plate is arranged and designed such that each support portion supports one zipper slider in closed position against force applied through the cover element onto the zipper slider. This is particularly relevant when closing the cover element while the zipper sliders are in closed position as then the engagement process for engaging the engagement section of the slider may lead to a force applied through the cover element to the slider. If no support element is arranged, the slider may avoid this force by moving away which would avoid the engagement of the slider.
In some preferred embodiments, the zipper slider comprises a pull element, wherein this pull element comprises two parts, i.e. it is formed as a two-piece element, the two parts being hinged to one another, preferably via an axle. The pull element is designed such that the first and second parts are pivotable around an axis with respect to one another from a flat configuration to only one side into an angled configuration. Accordingly, the flat configuration is defining a stop of the hinge movement to one side. Such a pull element design allows pushing the flat pull element to apply a shifting force onto the slider to bring it into the closed position, which may require some force as there is an engagement process involved if the cover element is closed. Preferably, in the angle configuration, an angle between the first and second part is 90° or more.
In some embodiments, the zipper is a double layer coil zipper with at least four rows of teeth, two arranged directly above one another to form pairs, wherein the pairs are arranged opposite one another to form two zipper sections above one another. The pairs of teeth may be formed from one coil.
In some embodiments, the engagement element comprises at least one ramp element with an inclined surface for guiding a releasing movement of the cover element. This extra guidance avoids that the cover element runs against items that are arrange in front of the closure device assembly as it directs the movement of the cover element upwardly.
The present invention also relates to a piece of luggage, in particular a suitcase like a hard shell suitcase, preferably without a frame construction, comprising a first body portion, a second body portion, and a zipper, the zipper being arranged between the first and second body portions, the piece of luggage or suitcase comprising a closure device assembly as described herein, wherein the at least one engagement element is arranged on the first body portion and the at least one buckle element is arranged on the second body portion.
The embodiments described herein are illustrative of some of the applications of the principles of the present invention. Numerous modifications and/or combinations of features that are individually disclosed may be made.
Preferred embodiments of the invention are described in the following with reference to the drawings, which are for the purpose of illustrating the present preferred embodiments of the invention and not for the purpose of limiting the same. In the drawings,
The suitcase 5 provides the casing with a front wall 53, a back wall 54, a top wall 55, a bottom wall 56, and first and second side walls 57, 58. The front wall 53 and the back wall 54 are forming major faces of the suitcase 5, wherein said first and second side walls 57, 58 are forming side faces of the suitcase 5 that extend between the front wall 53 and the back wall 54. The top wall 55 and the bottom wall 53 are forming top and bottom faces of the suitcase 5 that extend between the front wall 53 and the back wall 54.
Between the first and second body portions 51, 52 is arranged, along a remaining part of the free edges 510, 520, a zipper 60 for closing said suitcase 5 once the portions 51, 52 are in closed position, i.e. once the suitcase's interior space 50 is closed.
In a middle portion of the long narrow face of the first side wall 57 is arranged a closure device assembly 1 according to a first embodiment. The first embodiment shall now be explained with reference to
The closure device assembly 1 according to the first embodiment is designed as a toggle clamp with an engagement element 10 and a buckle element 11, the buckle element 11 having a knee-lever like design and therefore being pivotable in a three stage toggle motion.
The engagement element 10 is attached, with a base element 101, to the first side wall part of the first body portion 51. The base element 101 protrudes over the zipper 60 toward the second body portion 52. Moreover, the engagement element 10 is arranged substantially parallel to the first side wall 57 and provides a hook-like engagement portion 102 (cf.
Close to the periphery edge of the first body portion 51, i.e. close to the zipper 60, is arranged, on the base element 101, a locking device 13 comprising a pair of pivotable first and second bolt lever arms 131, 132. Said lever arms 131, 132 are connected to one another at one of their first ends by means of a common pivot joint 137, the joint 137 being arranged in the middle region of the base element 101 that faces the outside (cf.
The bolt lever arms 131, 132 are pivotable, against the action of a biasing member 130, relative to the base element 101 in a plane substantially parallel to the first side wall 57, i.e. substantially parallel to a main face of the base element 101, and toward the front wall 53 of the first body portion 51. Said pivoting motion brings the bolt lever arms 131, 132 from said locking position (cf.
The closure device assembly 1 further includes zipper sliders 15, which are designed for operation of and on said zipper 60. The sliders 15 comprise the engagement section 150 and the attachment section 152 are formed as a single-piece element (cf.
The engagement element 10 is arranged on the first body portion 51 such that the zipper sliders 15 extend, when in closed position, into said gaps 8 between the engagement element 10 and the buckle element 11 (cf.
The head portions 133,134 carry each a bolt 12 which protrude towards the second body portion 52, i.e. away from the front wall 53. The bolts 12 are arranged and designed to extend into the engagement sections 150 of the zipper sliders 15 once the bolt lever arms 131, 132 are in locking position and the zipper sliders 15 are in closed position, i.e. the puller rings 150 inserted into gap 8 (cf.
Once the zipper sliders 15 are caught by said bolts 12, the zipper sliders 15 are securely locked. Since the lever arms 131, 132 are pivotable (by actuation of the push element 16, see below) such that said bolts 12 disengage from the engagement sections 150, the zipper sliders 15 may be unlocked to freely move to open the zipper 60.
The engagement element 10 carries, on its base element 101, the hook-like second engagement portion 102 that protrudes outwardly and faces, with its open side, toward the first body portion 51. This second engagement portion 102 is adapted for mutual engagement with the buckle element 11.
The buckle element 11 is designed to be moved in a toggle-movement between an open position (cf.
The buckle element 11 is designed to cover, when in the engagement position, the engagement element 10. Thereby, the engagement section 150 and the locking device 13 are well protected underneath the buckle element 11. For that reason, the buckle element 11 comprises the plate-like cover element 110 that is hinged to a plate-like base element 113 of the buckle element 11 by means of connecting lever 112 (cf.
The base plate 113 is connected to the second body portion 52 such that the buckle element 11 may be moved relative to the second body portion 52 and may be brought into the engagement position when the body portions 51, 52 are closed or almost closed, i.e. when there is still a gap of 5 millimeters to 50 millimeters between parts of the edges 510, 520 close to the closure device assembly 1. Moreover, the base element 113 has a guide element 115 (cf.
The connecting lever 112 includes two lever arms 1121, 1122 (cf.
The connecting lever 112 may be hinged to the base plate 113 and to the cover element 110 with including a spring in the hinge such that the default position of the cover element 110 and the lever 112 is the one as depicted in
The first engagement portion 111 is a curved end portion of the cover plate 110 (cf.
Preferably, the lever 112 and the cover element 110 are hinged to one another such that a maximum pivot angle between them is smaller than 160 degrees, preferably smaller than 120 degrees, i.e. preferably the lever 112 and the cover element 110 cannot be brought to lie within one plane. Accordingly, the cover element 110 is, during engagement with the second engagement portion 102, inclined with respect to the base element 113, until the buckle element is in engagement position (cf.
After the first toggle motion, the buckle element 11 may be shifted in the second toggle motion toward the second body portion 52, i.e. the first and second body portions 51, 52 may be moved closer together. Since the first engagement portion 111 of the cover element 110 is hooked into the second engagement portion 102 of engagement element 10, the hinge portion of the cover element 110 describes, during this second toggle motion, a circular movement about the hinge 114 and comes into an maximum inclined position, while the engagement portion 111 is moved substantially laterally toward the second body portion 52 (cf.
After the second toggle motion, the hinge portion of the cover element 110 can be pushed down in a third toggle motion along said circular motion toward the base plate 113, whilst a distance between the first and second body portions 51, 52 is constantly reduced. At the end of the third toggle motion, the cover element 110 is parallel to the base element 113 and covers the lever 112, the closing device 13, and the actuation device 14. Moreover, the cover element 110 covers the gaps 8 such that it is only accessible along the zipper 60. Thereby, if the zipper sliders 15 are inserted with their engagement sections 150 into gaps 8, said engagement sections 150 are covered from all sides (cf.
Accordingly, closing the closure device assembly 1 helps in bringing together the first and second body portions 51, 52 of the suitcase 5, while the cover element 110 covers the sensitive parts of the zipper locking mechanism. This toggle action of the closure device assembly 1 thus may also help to properly close the suitcase 5, e.g., in case of overpacking. The body portions 51, 52 may be safely secured to one another by means of the closure device assembly 1 while the two portions 51, 52 are still spaced from one another and the zipper 60 is still open. Upon completing the toggle motion, the zipper may be conveniently closed. The toggle motion and the closing of the zipper may conveniently done single handed.
Furthermore, between the hinge portion and the first engagement portion 111 is arranged and actuation device 14.
At their free second ends, the levers 141, 142 have enlarged head portions 143, 144 such that both lever arms 141, 142 have a hammer-like design like the bolt lever arms 131, 132. The substantially cuboidal head portions 143, 144 have the same material thickness as the actuation lever arms 141, 142 and protrude over said arms 141, 142 away from the first engagement portion 111. Accordingly, the head portions 143, 144 of the actuation lever arms 141, 142 and the head portions 135, 136 of the bolt lever arm 131, 132 protrude to one another. In actuation position, faces of the head portions 143, 144 facing away from said first engagement portion 111 are inclined contact surfaces 145, 146 that are slanted to correspond with the respective inclined surfaces 135, 136 of the bolt lever arms 131, 132.
Moreover, the lever arms 141, 142 are adapted to be pivoted in a plane substantially parallel to the cover element 110 and relative to the cover element 110 out of the actuation position (cf.
The locking device 13 and the actuation device 14 are arranged such that upon engagement of the first and second engagement portions 111, 101, and after the first and second toggle motions, i.e. after the cover element 110 has been brought into the inclined position (cf.
The inclined surfaces 135, 136, 145, 146 are provided such that the come into parallel contact with one another at the end of the second toggle motion such that, during the third toggle motion, the actuation biasing member 140 may override the bolt biasing member 130 such as to move the bolts 12 from the release position into the locking position.
Biasing members 130, 140 (or others) may be mechanical springs, e.g. helical springs or leaf springs. Other means for providing the biasing force may be used.
After completion of the third toggle motion the closure device assembly 1 is closed (cf.
In order to release the locked zipper sliders 150, a push element 16 with a push button 160 is provided. The push button 160 is arranged along a periphery edge of the cover element 110, on the side facing the back wall 54, i.e. opposite of the first engagement portion 111 (cf.
The push button 160 extends along the hinge portion, i.e. along the lever 112 side edge of the cover element 110, and may be grasped and pushed out of its default position, preferably against the action of a biasing member, toward the first engagement portion 111. The push button 160 moves relative to the cover element 110.
The push element 16 comprises two rod-like contact elements 162 extending rectangular to the push button 160 and parallel to the cover element 110 toward the actuation device 14.
The principle of the push element 16 is now explained with reference to
The push element 16 further includes a guide pin 163 which is arranged between the two contact elements 162 and extends parallel thereto. Moreover, between the two contact elements 162 is arranged a lock 9, preferably a number combination lock.
The lock 9 comprises a plurality of number wheels 92 and a recess 91 arranged such that the guide pin 163 has to extend into the recess 91 if the push button 160 is moved from the default position (cf.
The lock 9 further comprises a locking pin 116 extending normally from the base element 113. The locking pin 116 has, close to its free end, a radial facing recess 1160 (cf.
During the third toggle motion, the inclined cover element 110 is pressed down such that the locking pin 116 runs into said recess 164 in the sledge 71. The sledge 71 has a ramp 710 (cf.
Upon depressing the push button 160, after having set the correct number combination with wheels 92, the sledge 71 is moved against its biasing member by the push button 160 from the locked position to the free position such that the buckle element 10 may be disengaged from the engagement element 10.
In the sledge 71 is also provided a TSA lock 7 (cf.
A further feature of the closure device assembly 1 is now described with reference to
In order to achieve this function, said bolts 12 of the locking device 13 have slanted surfaces 120 at their tips (cf.
In the following, a second embodiment of the closure device assembly 1 according to the present invention shall be explained with reference to
The closure device assembly 1 according to the second embodiment is also designed as a toggle clamp with engagement element 10 and buckle element 11, the buckle element 11 having a knee-lever like design and therefore being pivotable in a three stage toggle motion between the open position, the engagement position, and the closed position.
The closure device assembly 1 comprises the engagement element 10 (cf.
The closure device assembly 1 further comprises the buckle element 11 fixedly attached to the first body portion 51 via a base element 113 (cf.
As can be seen in
The engagement element 10 is fixedly attached to the first side wall part of the second body portion 52 by bolt connections extending through the suitcase wall and into the holes 107 (cf.
Details of the engagement element 10 are shown in
On the back side of the engagement element 10 is provided a back slot 105 that extends over more than half of the diameter of element 10 into the latter and in longitudinal direction. The slot 105 is arranged to receive the engagement section 1130 of the base element 113 (cf.
The buckle element 11 comprises a robust, single-piece cover element 110, for example, from a metal or plastics. Details of the cover element 110 are shown in
The cover element 110 may be made from a metal sheet material or from a synthetic material. It comprises a reception structure 1104 for housing the suitcase lock 9 that extends through the cover plate 1101 for manual operation from outside. The housing 1104 comprises recesses 164 for the guide pins 163 of the push element 16 (cf.
The cover element 110 has a substantially flat to surface and a structured bottom surface that comprises a hollow cylinder structure 1106 for receiving the TSA lock 7 (cf.
The bottom plate 119 is shown in
The bottom plate 119 has a first section 1190, a second section 1191, and a third section 1192 (cf.
The first section 1190 has a central through hole 1194 through which a screw 1199 (cf.
The second section 1191 is a narrowed transition section that connects the first and second sections 1190, 1192 to one another.
The third section 1192 has, in its back right quadrant, a rectangular recess 1197 (cf.
First axles 118 extend into through holes 1196 in side walls 1195 of the bottom plate 119 and through holes in the side walls 1102 of the cover element 110, thereby fixing, together with screw 1199 and reception 1109, cover element 110 and bottom plate 119 to one another. The first axles 118 also connect the cover element 110 and bottom plate 119 to the connecting member 112 in a pivotable manner. Second axles 1180 (cf.
In said interior space are further arranged, besides the locks 7 and 9, a shiftable latch element 17 and said locking device 13 as shown in
The locking device 13 is shown in
The two levers 131, 132 receive the screw 1199 and cylinder 1109 through their central recesses 1311, 1321 as shown in
The biasing member 138 is substantially U-shaped having two legs connected by loop 1384. One leg has two separate contact tongues 1381, 1382. The first contact tongue 1381 contacts the recessed arm of the first lever 131; the second tongue 1382 contacts the recessed arm of the second lever 132. The loop 1384 is received in pin 1105 of the cover element 110 (cf.
The latch element 17 corresponds functionally to the actuation device 14 of the first embodiment and is shown in isolation in
The push button 160 is inserted into the internal space between the cover element 110 and the bottom plate 119 and has a guiding structure 167 from webs for guiding the latch element 17 perpendicularly to the zipper 60 (cf.
The latch base plate 170 has a further recess 171 (cf.
The push element 16 has in its side walls 169 longitudinal holes 1690 (cf.
Moreover, the buckle element 11 is equipped with an automatic mechanism controlling the movement of the latch element 17. This automatic mechanism allows the latch mechanism (latch plus automatic mechanism) to function like the actuation device 14 as described above, i.e. that said actuation device 14 is adapted for moving said bolt 12 against said bolt biasing member from said release position into said locking position upon closing the closure device assembly 1.
Said automatic mechanism functions as follows. The base plate 170 of the latch element 17 has a further blind hole 174 open toward the lock bolt 18. In the center of the blind hole 174 is a smaller through hole 175 for the pin 182 extending downward from the lock bolt 18. The through hole 175 and the previously mentioned through hole 1198 in the bottom plate 119 (cf.
Accordingly, the automatic mechanism ensures that the locking device 13 is in locking position if the closure device assembly is closed. If then the push button 160 is pushed, the latch 17 moves and the sliders 15 are released. If the cover element 110 is not moved, the latch 17 travels under action of biasing member 138 back into initial position upon release of the push button 160 as the bolt pin 182 cannot protrude over the bottom surface of bottom plate 113 such that the lock bolt 18 is prevented from engaging into blind hole 174. If the cover element 110 is, however, moved the lock bolt 18 engages into blind hole 174 and the sliders 15 are released until pin 182 is pushed back to be flush with the bottom plate 113.
The push button 160 has the slot 168 such that the push button 160 may not be pushed from initial position to actuation position if the lock bolt 18 engages into blind hole 174 and pin 182 protrudes through the through hole 175.
Moreover, the TSA locking cylinder 7 is arranged in the hollow cylinder 1106. At the bottom side, the TSA cylinder 7 has a downward facing TSA pin (extending parallel to pin 182). This TSA pin engages into a groove 172 arranged on the top surface of latch element 17 (cf.
The base element 113 of the buckle element 11 is fixedly connected to the first body portion 51 by means of bolt connections including the receiving sections 1136 (cf.
The connecting element 112 is hinged via second axles 1180 to the hinge portions 114 arranged on the base element 113. The hinges/axles are biased by means of biasing member 117 (see below).
The base element 113 is a single-piece element from sheet metal or plastics and has a tapering engagement section 1130, a first section 1131, a second section 1132, and a third section 1133.
The engagement section 1130 is designed to extend into back slot 105 of the engagement element (cf.
Accordingly, the buckle element 11 engages into the engagement element 10 from both sides, i.e. with the engagement web 1110 and with the engagement section 1130.
The first section 1131 has recesses 1135 for the sliders 15. The recesses 1135 have grooves 11350 for receiving and guiding the lower part of the engagement sections 150 of the sliders 15 during their engagement with the bolts 12. Moreover, the first section 1131 has a bulge for receiving the head of the screw 1199.
The second section 1132 carries two of the receiving sections 1136 and in part the hinges 114 and is shaped to extend over part of the zipper 60.
The third section 1133 carries the remaining part of the hinges 114 and two further receiving sections 1136 for connection with the suitcase 5. Moreover, the third section provides the hook element 1137 which secures the latch 17 (and thereby the cover element 110), if the latch is in initial position.
The single-piece connecting element 112 is hinged via hinges 114, 1180 to the base element 113 and via hinges 1107, 118 to the cover element 110. The connecting element 112 comprises the first lever atm 1121 and the second lever arm of 1122. The first and second lever arms 1121, 1122 have at their ends through holes for receiving the first and second axles 118, 1180, respectively. Moreover, the first and second lever arms 1121, 1122 are connected to one another via the connector element 1123. This increases stability and allows for a synchronous movement of both lever arms 1121, 1122 such that the cover element 110 may remain substantially parallel to the base element 113 during pivoting about axles 118, 1180 whilst allowing inclined position when engaging with the engagement element 10.
Accordingly, the base element 113, the connecting lever element 112 and the cover element 110 with its bottom plate 119 form a knee-lever for toggle motion or, in other words, a toggle-clamp like mechanical structure. The cover element 110 may be pivoted relative to the base element 113 between the open and engagement positions. In the engagement position the cover element 110 extends over the zipper 60 engages with the engagement element 10 on the second body portion 52. This is a first securing stage in which the suitcase 5 may still be open, the gap between the body portions 51, 52 may be a few centimeters. The interior space of the suitcase 5 is accessible. Upon pulling the cover element 110 back to the base element 113, the suitcase 5 closes completely. Engagement section 1130 engages into the engagement element 10. The cover element 110 may then still be somewhat inclined. In this state, the latch 17 is normally in activation position (if the pin 182 has not been manually pushed before closing). Upon pushing the cover element 110 down into the closed position where it becomes to be arranged substantially parallel to and in contact with the base element 113, the hook element 1197 engages into the recesses 1197 of the bottom plate 119, then into the recess 166 of the push element 16, and then into recess 171 of the latch element 17. Upon contact, the pin 182 is pushed against spring 181, the latch is free to move to initial position through action of biasing member 138 and the hook-element 1137 is caught in latch 17 and the locking device 13 moves to locking position, securing any slider 15 in locking position.
The sliders 15 may also be pushed into the closed buckle element 11 as the slanted bolt surface 120 allows that the slider 15 pushes the bolt back whereupon the biasing member 138 snaps the bolt 12 into engagement after the engagement section 150 is in place.
It is to be noted that in both, the first and second embodiment, the zipper sliders 15 may be released without opening the cover element 110. Accordingly, the push button 160 of a closed closure device assembly 1 may be pressed and the zipper sliders 15 may be removed without moving the cover element.
Moreover,
The base element 113 in the embodiment according to
Preferably, the material that forms the second body portion 52, e.g. polycarbonate, is recessed such that the counter plate 19 may directly contact, with its cylinders 196 with recesses 194, the base element 113. Accordingly, the counter plate 19 is fixedly connected to the base element 113 which gives a compact and secure closure device assembly 1.
In order to adapt for changing wall thicknesses of different suitcase models, preferably elastic layer materials may be placed between the wall parts of the suitcase 5 and the closure device assembly 1.
Moreover,
These first and second support protrusions 191, 192 are designed such that, when the sliders 15 are in closed position, the sliders 15 are guided from below by the support protrusions 191, 192. If, for example, one is closing the buckle element 11 while the sliders 15 are in closed position, the buckle element 11 exerts a downward force onto the sliders 15 via its bolts 12. The support protrusions 191, 192 then avoid that the sliders 15 move downward and away from the bolts 12. Therefore, the support protrusions 191, 192 ensure that the bolts 12 engage into the engagement sections 150 of the sliders 15 for properly closing the closure device assembly 1.
Moreover,
From the
Generally, it is preferred to use a zipper 60 of double layer coil zipper design as this further increases the security of the piece of luggage. Moreover, a pull tab design according to
