Abstract
Description
[0001] The present invention relates to a roll-top closure for a piece of luggage, preferably for a piece of luggage in the form of a backpack and / or a bicycle bag.
[0002] Roll-top closures for luggage are known, among other things, from German patents DE 299 14 374 U1 and DE 20 2010 000 734 U1. They are particularly popular for luggage, primarily because they are quick and easy to open and provide a watertight seal.
[0003] A disadvantage of roll-top closures is the lack of security against removal, especially when the piece of luggage is out of reach or sight of the luggage owner.
[0004] The following situations are relatively common in everyday life: A pannier, also known as a bicycle bag, is attached to the luggage rack of the owner's bicycle and secured to the bike with a lock, for example. If the bicycle is parked and locked in a public place, such as during shopping, the pannier cannot be removed due to the anti-theft device. However, the roll-top closure can be opened within seconds, allowing access to the contents. Thus, the contents can be removed relatively quickly by unauthorized persons, even without stealing the pannier itself. The same applies to a backpack with a roll-top closure if it is left out of the owner's reach or sight, for example, on a publicly accessible luggage rack of public transport (e.g., airplane, bus, train).
[0005] Due to the quick-opening closure, luggage with a roll-top closure inherently poses a high risk of theft of its contents if the luggage is even briefly out of the reach or sight of the luggage owner.
[0006] As a result, the owner of the luggage is often forced to carry it with them at all times or keep it within reach and sight. In many cases (e.g., when shopping), this restricts the owner's freedom of movement and action.
[0007] The present invention is based on the objective of eliminating the disadvantages arising from the prior art and of further developing the known roll closures in such a way that they can be securely closed to prevent removal, at least in the short term.
[0008] To solve this problem, the invention provides the roll-top closure for a piece of luggage according to claim 1 and the piece of luggage with such a roll-top closure according to claim 10.
[0009] Disclosed is a roll-top closure for a piece of luggage, preferably for a backpack and / or a bicycle bag, comprising a reversibly rollable tube section with an end-mounted luggage compartment opening, a closure and at least one locking device, wherein in an unrolled or stretched state of the tube section the luggage compartment opening can be closed with the closure and the closure in the closed state can be additionally secured one or more times with the at least one locking device, wherein the tube section can be reversibly rolled up and unrolled when the luggage compartment opening is closed and the closure is secured.
[0010] The closure and additional locking mechanism provide at least temporary security against unauthorized removal of the contents of the luggage, allowing the owner to temporarily leave the luggage out of reach or sight. Opening the luggage compartment would require destroying this closure and the additional locking mechanism, or even destroying the luggage itself. Such actions are time-consuming and attract public attention, which generally deters unauthorized individuals from attempting them. In particular, the closure and locking mechanism can be operated even when the hose section is fully extended, meaning even when the luggage is completely full. Furthermore, when the hose section is rolled up, the closure and locking mechanism are also retracted and protected from the elements.
[0011] The secure roll-top closure is primarily designed to deter opportunistic thieves. It is not intended for leaving luggage unattended with valuables on the bicycle for several days. However, the roll-top closure should allow the bicycle to be left unattended for a few hours – for example, while visiting a café or exploring the city – without worry. While cutting open the luggage would theoretically be possible, it would attract significantly more attention and thus act as an additional deterrent. The section of the inner tube is preferably made of a cut-resistant, preferably fiber-reinforced fabric.
[0012] Despite increased security, the roll-top closure according to the invention offers the practical advantage of quick and easy access to the luggage compartment.
[0013] It can be advantageous if the hose section has a flap that folds over the luggage compartment opening as a closure. A flap is easy to operate and can be easily opened and closed again.
[0014] It can prove useful if the locking mechanism comprises two arms that can be interlocked to secure the closure over the closed flap. Interlocking the arms over the closed flap preferably renders the flap inaccessible and thus prevents it from being opened. The interlocking arms provide a particularly robust mechanical locking mechanism.
[0015] It can be advantageous for the hose section to have a locking pin that penetrates the closed flap and the folded arms. The locking pin forms a central connecting element that interacts with the flap and the arms. The locking pin ensures that the flap and arms are aligned securely and without twisting. This allows the hose section to be easily rolled up when the flap is closed and the arms are folded, while the luggage compartment opening remains tightly sealed.
[0016] It can be helpful if the locking mechanism has a lock to secure the closed flap and the folded arms to the locking pin. Since both elements interact with the locking pin, a single lock on the locking pin can additionally secure both the closure (flap) and the locking mechanism (arms).
[0017] It can be advantageous if the flap and an adjacent support section of the hose section are reinforced with flexible support strips, preferably made of plastic, wherein the hose section located between the support strips forms a pivot axis for the flap, with the support strips lying parallel to one another when the flap is closed. The support strips allow the flap and the adjacent support section to be laid flat and tightly against each other. When the hose section is rolled up, the flap and the support section are pressed so firmly together by the embedded support strips that the luggage compartment opening is securely closed to prevent removal and, ideally, no moisture can penetrate.
[0018] It can prove practical if each of the arms is designed as an essentially rigid structural strip, preferably made of metal, with an opening at one end, wherein the structural strip is predominantly embedded in the hose section so that the opening at the end projects beyond the hose section. The arms thus largely form part of the hose section and are integrated with it into a deformable structure. At the same time, the structural strips form a stable upper edge of the hose section and thus stabilize the luggage compartment opening. The stability of the structural strips ensures a high level of tamper resistance.
[0019] It can be advantageous if the arms, when spread, are aligned in line with the support section adjacent to the flap, and, when folded and the flap is closed, are aligned parallel to the flap and the adjacent support section. This arrangement allows for a particularly tight seal of the luggage compartment opening because the arms, the flap, and the support section are pressed firmly together when the hose section is rolled up, ensuring that the luggage compartment opening is securely closed and ideally preventing any moisture from penetrating.
[0020] It can be advantageous if an edge section of the hose section, containing the locking pin, is stiffened with a flexible edge strip, preferably made of plastic, wherein this edge section is arranged between the flap and the adjacent support section when the flap is closed, so that the edge strip is aligned parallel to the support strips. The flap and the adjacent support section are preferably formed on the rear wall of the hose section, and the arms are embedded in the rear wall of the hose section, while the edge section containing the locking pin is located on the front wall of the hose section. When the flap is closed, the flap overlaps the luggage compartment opening and holds the front and rear walls of the hose section tightly together, lying flat against each other.When the arms are folded, the side sections of the hose segment, in which the arms are embedded, are folded onto the middle section of the hose segment, where the flap and the edge section with the locking pin are located. In this state, the hose segment is particularly compact, with the hose walls lying flat and folded on top of each other, making the hose segment easy to roll up.
[0021] Another aspect of the invention relates to a piece of luggage, preferably a backpack and / or a bicycle bag, with a roll-top closure according to one of the preceding embodiments.
[0022] Further advantageous embodiments result from combinations of the features disclosed in the claims, figures and description. Terms and definitions
[0023] A roll-top closure, for example on a dry bag, works by repeatedly folding and securing the top edge to create a mechanical barrier against water and dust. At the top of the dry bag, there are usually two stiffened plastic or fabric strips that form a seal. When these strips are folded and rolled up, the fabric is compressed so tightly that no moisture can penetrate. Before closing, excess air should be squeezed out to minimize the volume. For reliable weatherproofing, the edge must be folded over at least three times. With fewer rolls (one or two), the dry bag is usually only splash-proof. The two ends of the rolled-up bag are then brought together in the opposite direction of the roll and secured, for example, with a buckle (click closure). This creates a practical carrying handle. If you want to use the bag on the water, for example...When used as a duffel bag or buoyancy aid, air intentionally trapped inside the bag can provide buoyancy, ensuring the bag always stays afloat. The rolling direction is crucial for creating optimal tension and airtightness. Brief description of the characters
[0024] They show: Fig. 1 A contrasted photographic view of a roll-top closure according to the invention for a bicycle bag, comprising a rollable hose section with an end-end luggage compartment opening, which in an unrolled or stretched state of the hose section can be mechanically closed by means of a flap that overlaps the hose end in the flat state and in the closed state can additionally be locked multiple times by interlocking arms projecting laterally from the hose end on a central locking pin above the flap, wherein the hose section can be reversibly rolled up and unrolled in the closed and locked state of the opening, wherein the luggage compartment opening is held in the open position by a user (whose hand can be seen in the picture).

Detailed description of preferred embodiments
[0025] The preferred embodiments of the invention are described in detail below with reference to the accompanying figures. Luggage item G
[0026] An exemplary piece of luggage G with a roll-top closure 1, in the form of a bicycle bag, includes a rear, hook-shaped carrying device (not shown) for attaching the bag to the luggage rack of a bicycle. The body of the luggage G consists largely of a flexible, waterproof, and optionally impregnated plastic fabric, which partially or completely forms the hose section S of the roll-top closure 1. The rear of the luggage G, where the carrying device is located, is reinforced with a plastic plate or is made entirely of one. The rear plastic plate provides stability during transport and prevents, among other things, the luggage G from deforming (e.g., bulging) when filled or during riding, and thus from getting caught in the spokes of the bicycle. Hose section S
[0027] The tube section S forms the upper part of the luggage item G and essentially consists of a front and a back wall, which are sewn together along the edges to form the luggage compartment opening O at the top. This rollable tube section S forms a luggage compartment that can be filled from above through the luggage compartment opening O and can be closed using the roll-top closure 1. At the end of the tube that forms the luggage compartment opening O, the tube section S is preferably folded inwards and stiffened by incorporating various strip-shaped stiffening elements, which are described below. When the tube section S is unrolled or stretched, the front and back walls of the tube section S lie close together, so that the tube section S can be rolled up starting from the upper end.Ideally, before rolling up the hose section S, any trapped air is smoothed out of the luggage compartment opening O, which makes rolling easier. Take 2
[0028] The luggage compartment opening O can be mechanically closed by a flap 2 when the hose section S is unrolled or stretched. The flap's open position is described in Fig. Figure 2 shows the closed state of the flap. Fig. 3 to recognize.
[0029] The flap 2 is located centrally on the rear wall of the tube section S. The flap 2 can be pivoted or folded about a pivot axis 2e, which is aligned at the tube end perpendicular to the tube axis and parallel to the rolling axis of the roll-top closure 1. Because the flap 2 is hinged to the rear wall of the tube section S, the luggage compartment can be conveniently opened even when attached to a bicycle or carried on a user's back, without the flap 2 interfering with loading / unloading.
[0030] The flap 2 and an adjacent support section of the back wall of the hose section S are stiffened with flexible, approximately rectangular, and flat support strips (not shown), e.g., made of plastic. These support strips are, for example, sewn into the folded-over upper edge of the back wall and are not visible from the outside. The portion of the hose section S located between the support strips, due to its flexibility, forms a kind of rigid hinge or pivot axis 2e for the flap 2. The pivoting capability is achieved by the fact that no stiffening is provided between the flap 2 and the underlying support section, meaning that the flap 2 and the underlying support section are connected solely by the flexible material of the hose section S.
[0031] The flap 2 is, in the unrolled or stretched state of the hose section S, by folding between the open position, in which the flap 2 extends beyond the luggage compartment opening O in the extension of the hose section S and releases the luggage compartment opening O (cf. Fig. 2), and the closed position in which flap 2 overlaps and thus closes the luggage compartment opening O (cf. Fig. 3), transferable.
[0032] To mechanically close the luggage compartment opening O, the flap 3 is folded around the pivot axis 2e onto the front wall of the hose section 5, so that it overlaps the end of the hose when the luggage compartment opening O is closed. In the closed state, the flap 2 holds the front and rear walls of the hose section S together in a flat position, thus preventing the luggage compartment opening O from being opened. The support strips in the flap 2 and in the support section are shaped and aligned so that they lie parallel and flat on top of each other when the flap 2 is closed.
[0033] To fix the flap 2 in the downward-folded position, the flap 2 includes two magnets 2b above the pivot axis 2e. Two corresponding magnets 2c are located in the stiffened support section of the rear wall of the hose section S below the pivot axis 2e. By pivoting the flap 2 about the pivot axis 2e, the two magnets 2b in the flap 2 are brought into alignment with the two magnets 2c below the pivot axis 2e, thus magnetically fixing the flap 2 in the downward-folded or closed position. Fig. 3) When flap 2 is closed, the magnets 2b in flap 2 and the magnets 2c in the support section can interact with further magnets (not shown) in the edge section of the front wall of hose section S which has the locking pin 3.
[0034] To align with the front wall of the hose section S, the flap 2 has a central, approximately rectangular opening 2a. When the flap 2 is closed, a plug pin 3, projecting outwards from the center of the front wall of the hose section S, penetrates the opening 2a.
[0035] The inner contour of opening 2a is matched to the outer contour of locking pin 3 such that opening 2a fits precisely over the wedge tip 3d of locking pin 3, aligning itself below the wedge tip 3b on the base 3a of locking pin 3. A pull tab 2d on the flap 2 enhances ease of use and facilitates operation of the flap 2. When the locking pin 3 penetrates opening 2a, the flap 2 is securely and rotationally fixed to the locking pin 3. This alignment of the closed flap 2 on the locking pin 3 is crucial to ensure that the front and rear walls of the hose section S lie flat against each other when the flap 2 is closed, resulting in a compact and rollable arrangement when the luggage compartment opening O is tightly sealed. Locking pin 3
[0036] The locking pin 3 comprises a base 3a with an approximately rectangular cross-section and a wedge-shaped tip 3b that tapers from the base 3a to the free end. In the area of this tip 3b, the locking pin 3 has an opening 3c for a padlock 6.
[0037] Below the wedge tip 3b, on the short sides of the rectangular base 3a, are lateral receptacles for hooking the arms 4, 5. The locking pin 3 is designed to penetrate the flap 2 in the closed position and the arms 4, 5 in the interlocked position.
[0038] An edge section at the upper end of the front wall of the hose section S, featuring a locking pin 3, is stiffened by a flexible, approximately rectangular and flat edge strip, preferably made of plastic. The locking pin 3 projects centrally outwards or forwards from this edge section.
[0039] The edge strip has approximately the same outline as the support strip in flap 2 and the support strip in the adjacent support section. When flap 2 is closed, the edge section of the front wall, which includes the locking pin 3, is positioned between flap 2 and the adjacent support section of the rear wall of hose section S, so that the edge strip is aligned parallel to the support strips. This flat arrangement of the strips improves the tightness of the closure and the ability to roll up hose section S when flap 2 is closed.
[0040] The edge section preferably has further magnets or metal plates (not shown). These magnets interact magnetically with the magnets 2b in the flap 2 and the magnets 2c in the support section of the rear wall of the hose section S below the pivot axis 2e, so that when the luggage compartment opening O is closed, the edge section is held tightly against the rear wall of the hose section S, and the closed flap 2 is in turn held tightly against the edge section.
[0041] On either side of the edge strip, in the edge section at the upper end of the front wall of the hose section S, further flexible, approximately rectangular side edge strips are sewn in (not shown), which are shaped approximately similarly to the sewn-in sections 4d, 5d of the arms 4, 5 and are folded onto the flap 2 when the arms 4, 5 are folded in or crossed, in order to assume a compact and rollable arrangement of the hose section S when the luggage compartment opening O is tightly closed.
[0042] When the luggage compartment opening O is opened, the flexible edge strip and the adjacent side edge strips allow the edge section at the upper end of the front wall of the hose section S to deform approximately in an arc shape (cf. Fig. 1) and thus allows good access to the luggage compartment. Arms 4, 5
[0043] At the end of the tube forming the luggage compartment opening O, the rear wall of the tube section S comprises two essentially rigid arms 4, 5, which are designed as essentially rectangular structural strips with end buckles 4a-c, 5a-c, e.g., made of metal. The structural strips are largely sewn into the rear wall of the tube section S, so that the majority 4d, 5d of the arms 4, 5 lies within the rear wall and is not visible externally, while only the end buckles 4a-c, 5a-c protrude from the tube section S. The structural strips are fastened with rivets 4e, 5e (see figure). Fig. 6 and Fig. 7) secured in the back wall of hose section S.
[0044] In an unrolled or stretched state of the hose section S, the arms 4, 5 spread out laterally, essentially in extension of the support section of the back wall of the hose section S.
[0045] The parts of the rear wall of hose section S located between the support strip in the support section and the arms 4, 5 form, due to their flexibility, rigid joints or pivot axes for the arms 4, 5. The arms 4, 5 can be reversibly moved from the spread position ( Fig. 2, Fig. 3) into a crossed position in which the arms 4, 5 are crossed over the closed flap 2 ( Fig. 6), are transferred. While arms 4, 5 extend in the spread position in a line with the support section adjacent to flap 2 ( Fig. 2, Fig. 3), in the interlocked position with flap 2 closed, they are aligned parallel to flap 2 and the adjacent support section ( Fig. 6).
[0046] When arms 4 and 5 are folded in, the two side parts of hose section S are also folded onto the middle part of hose section S below flap 2, as shown in the Fig. 5-7 shown.
[0047] Each of the arms 4, 5 comprises at its exposed end a buckle 4a-c, 5a-c, which has a substantially rectangular frame 4a, 5a with a substantially rectangular opening 4b, 5b and a hook 4c, 5c located at the end extending away from the arm base and pointing towards the arm base. This buckle 4a-c, 5a-c allows each arm 4, 5 to engage with the locking pin 3, such that the locking pin 3 penetrates the opening 4b, 5b, with the respective hook 4c, 5c engaging the associated lateral receptacle in the base 3a of the locking pin 3. The inner contour of the opening 4b, 5b is adapted to the outer contour of the locking pin 3 in such a way that the frame 4a, 5a fits just over the wedge tip of the locking pin 3 in order to engage with the hooks 4c, 5c below the locking pin 3 in the lateral receptacles of the locking pin 3, possibly supported by a pulling movement in the direction of the arm base.When the locking pin 3 penetrates the openings 4b, 5b, the arms 4, 5 are secured against rotation and position on the locking pin 3. This alignment of the interlocking arms 4, 5 on the locking pin 3 is important to achieve a compact and rollable arrangement when the luggage compartment opening O is tightly closed (. Fig. 6). Castle 6
[0048] In this case, the lock 6 is a separate 3-digit combination lock, the shackle of which can be engaged in the opening 3c of the locking pin 3 to secure the closed flap 2 and the interlocked arms 4, 5 to the locking pin 3. When the lock 6 is closed, the arms 4, 5 cannot be released from the locking pin 3 and consequently the flap 2 cannot be opened.
[0049] With flap 2 closed and arms 4, 5 folded, the hose section S can be rolled up. When rolled up, the hose section S can be secured with a hook (not shown) attached to the rear wall. Depending on the load in the luggage compartment and the number of times the hose section S is rolled up, the hook is attached to one of the retaining eyelets 7 on the front wall of the hose section S.
[0050] To open the luggage compartment opening O, the hose section S must be unrolled again. Then the lock 6 can be opened and removed from the opening 3c of the locking pin 3, so that the arms 4, 5 can be returned to their spread position and the flap 3 can then be opened.
[0051] The embodiment described is merely exemplary. Variations are possible within the scope of the claims.
[0052] The arms 4 and 5 can, for example, be folded in a different order than described above, with the right arm 5 being folded in first and then the left arm 4. It is also possible, for example, to use only one arm as a locking mechanism, although the described variant with two arms 4 and 5 is preferred due to its symmetry. Second embodiment (Fig. 8)
[0053] The second embodiment is based on the first embodiment described above and has largely identical features, which are identified by identical reference numerals. To avoid repetition, reference is made to the preceding description for identical or similar features. The following section primarily explains the differences from the first embodiment.
[0054] In the second embodiment according to Fig. In section 8, the roller closure 1 has an integrated combination lock 6 on the outside of the flap 2 instead of the combination lock 6. This combination lock 6 is located above the central opening of the flap 2 on the outside of the flap 2 and is designed to engage the locking pin 3 on the outside of the front wall of the hose section S when the flap 2 is closed and when the luggage compartment opening O extends through the central opening of the flap 2 from the inside of the flap, so that the locking pin 3 snaps into a lock catch.
[0055] In contrast to the first embodiment, when closing the luggage compartment opening O, the arms 4, 5 are preferably first interlocked over the locking pin 3 before the flap 2 is closed over the interlocked arms 4, 5.
[0056] By turning the combination lock 6, lock 6 is locked against the locking pin 3, so that the flap 2 and the arms 4, 5 can no longer be detached from the locking pin 3. By setting the predetermined number combination, the combination lock 6 can be unlocked again, so that the flap 2 can be opened and the arms 4, 5 can also be detached from the locking pin 3. The luggage compartment opening O can then be opened again. Third embodiment (Fig. 9)
[0057] The third embodiment is based on the previously described embodiments and has largely identical features, which are identified by identical reference numerals. To avoid repetition, reference is made to the preceding description for identical or similar features. The following section primarily explains the differences compared to the preceding embodiments.
[0058] In the third embodiment according to Fig. In embodiment 9, the roll-top closure 1, unlike the preceding embodiments, does not have a flap 2. Instead, the front and rear walls of the hose section S are pressed directly together to close the luggage compartment opening O. For this purpose, a pin 8 located on the inside of the rear wall of the hose section S is inserted from the inside through an opening in the front wall of the hose section S into the integrated combination lock 6 located on the outside of the front wall, in order to snap into a locking mechanism. The pin 8 and the locking mechanism in the combination lock 6 form a pressure-fit closure for connecting the walls of the hose section S that form the luggage compartment opening O.
[0059] The arms 4 and 5 are interlockable as in the preceding embodiments. In contrast to the first embodiment, the arms 4 and 5 are interlocked above the combination lock 3, which acts as the locking pin 3 for the arms 4 and 5. By turning the combination lock 6, the pin 8 and the arms 4 and 5 are locked to the lock 6, so that the pin 8 and the arms 4 and 5 cannot be released from the lock 6. By setting the predetermined combination, the combination lock 6 can be unlocked again, so that the pin 8 and the arms 4 and 5 can be released from the combination lock. The luggage compartment opening O can then be reopened.
