[0001] LOCK, LOCKER INSERT WITH SUCH A LOCK, LOCKER ARRANGEMENT WITH SUCH A LOCKER INSERT
[0002] The present invention relates generally to a lock, in particular to a double-bit lock, a locker insert with the lock and a locker assembly with the locker insert.
[0003] BACKGROUND OF THE INVENTION
[0004] Locks for a single locker compartment and a locker arrangement with multiple locker compartments are generally known, where each individual locker compartment can be locked with its own lock. Safe deposit boxes are often offered as rental safe deposit boxes by banks or private providers to allow customers to securely and discreetly store valuables without the control of the safe deposit box provider. Safe deposit boxes are typically used for precious metals, jewelry, coins, or documents. Due to increased security needs, low interest rates, and rising account management fees, the demand for safe deposit boxes has risen to such an extent that demand exceeds the supply of safe deposit boxes that are economically viable for the customer. The rental cost for a safe deposit box is based, among other things, on the safe deposit box dimensions. Advancing digitalization is now also omnipresent in the financial sector.Large sums of currency are often managed or transferred digitally these days. In recent years, so-called cryptocurrencies have also become established. To prevent third-party access, the currency is protected by a key or code, which the owner maintains, for example, on a data storage device or piece of paper.
[0005] Along with digitalization, customer needs for rental lockers have also changed. Often, only codes, data storage devices such as hard drives or USB sticks, and small amounts of tangible valuables are stored in lockers. This also reduces the effective space required. However, the smallest lockers available on the market often have a minimum width of 25 cm to 30 cm and a minimum height of 5 cm, making them significantly larger than customers actually need today. However, the minimum width is limited by the lock dimensions and the locker design. This often results in rental costs that are not economically viable for the customer.
[0006] Standard safe deposit boxes consist of a shaft that can be securely locked with a flap. A removable cash box is placed within the shaft. Customers deposit their valuables in the box. The flap can be equipped with a high-security lock that can only be opened using a customer key and a bank key, based on the dual-authority principle. This principle can be implemented either with two separate locks or a special lock with a pre-locking or bank lock. This design provides maximum security, but efficient use of space takes a back seat.
[0007] For example, DE 84 35 584 U1 discloses a bank safe deposit box with a drawer in a shaft. The drawer can be locked behind a lockable safe deposit box door or flap. The previously described standard commercial arrangement is supplemented here by a security lock in the drawer. The combination with the lockable safe deposit box door further increases burglary protection. At the same time, the safe deposit box housing is widened by a locking shoulder, counter to efficient use of space.
[0008] DE 22 03 702 A discloses a door lock for safe deposit box systems. Pre-locking by the bank employee can be effected via remote control. The door lock comprises a bolt whose locking length is equal to a locking distance. GB 2 293 964 A discloses a safe deposit box arrangement with lockable flaps. The lockable flaps are connected to the respective shaft via a hinge. As with standard safe deposit boxes, a conventional two-key lock is integrated into the side of each flap. A lateral vertical rib is formed on the vertical divider in the area of the bolt. The lateral rib protrudes into the shaft and serves as a locking device for the bolt. This limits the width of a safe deposit box insert, since the ribs locally reduce the width of the shaft in this area.
[0009] The locks installed are often standardized high-security locks (HSS). These require a minimum amount of space for installation, which is why lockers cannot be reduced in width at will.
[0010] The object of the present invention is to provide a lock, in particular for a locker insert, a locker insert and a locker arrangement, in which the disadvantages mentioned above are at least partially solved.
[0011] SUMMARY OF THE INVENTION
[0012] This object is achieved by the lock according to claim 1, the locker insert according to claim 8, and the locker arrangement according to claim 11.
[0013] According to a first aspect, the present invention provides a lock, in particular a double-bit lock for a safe deposit box insert, having a lock frame for receiving a lock mechanism, a locking tongue comprising a locking block with a locking section, wherein a locking window is arranged in a locking-side side surface of the lock frame, which is designed according to a cross-sectional contour of the locking section, the locking block being adjustable via the locking tongue along a locking path between a closed position and an open position, characterized in that a locking length of the locking block in the closing direction is smaller than the locking path. The safe deposit box insert can be a bank safe deposit box or a rental safe deposit box.
[0014] The double-bit lock can be locked with a double-bit key. Due to its mechanical design, the double-bit lock is considered a high-security lock. The two key bits of the double-bit key can be arranged independently of each other. One key bit can move the locking tongue with the locking block, while it can raise a tumbler to a certain height. The lock can be a high-security lock, which is standardized according to DIN EN 1300 for the classification of high-security locks.
[0015] The locking block can be connected to the locking tongue or be designed as a single piece with the locking tongue. The locking length is shorter than the locking distance, allowing the locking tongue to be shortened overall. This ratio of locking length to locking distance allows the locking block to be shortened without reducing the security of the lock. This shortening also allows a locking section for the locking process to be shortened. This reduces the minimum installation space required for installing the lock in a locker.
[0016] Further aspects and features of the present invention emerge from the dependent claims, the accompanying drawings and the following description of preferred embodiments.

[0028] DESCRIPTION OF EMBODIMENTS
[0029] Figure 1 illustrates an embodiment in accordance with the present invention. Before a detailed description, general explanations of the embodiments follow.
[0030] The term "bolt section" refers to the portion of the locking tongue or locking block that protrudes from the lock frame in a closed position and is received in a locking recess. The bolt section can be a locking length.
[0031] The term “locking position” refers to the position of the lock in which the locking block is extended and protrudes with the locking section over the locking window from the lock frame of the lock.
[0032] The term "open position" refers to the position of the lock in which the locking block is retracted. In this position, the locking window is not penetrated by the locking block.
[0033] The ratio of locking length to locking distance can be 1:2.4. In the illustrated example, the locking length can be 5 mm and the locking distance 12 mm. The locking distance can be the bolt stroke. This ratio can result in the advantage of a shorter bolt section and a narrower or more space-saving design of the strike plate.
[0034] There are embodiments in which an insertion geometry is formed at the end of the locking block, which guides the locking block into the locking window in a centering manner when it is adjusted from the open position to the closed position.
[0035] The locking block can be positioned within the lock frame with a slight vertical clearance. This means that the locking block may not always be centered relative to the locking window. In the open position, the locking block may be positioned eccentrically relative to the locking window.
[0036] The insertion geometry can be an element that serves as a centering aid from the locking block to the locking window. When the locking block moves from the open position to the closed position, the locking block can center itself to the locking window via the insertion geometry. This eliminates the need for an additional guide aid within the lock frame. The insertion geometry can also or alternatively be formed in a section of the locking window.
[0037] There are embodiments in which the insertion geometry comprises a ramp-like insertion bevel which is formed starting from a front edge of the locking block.
[0038] The lead-in chamfer can be formed from the upper and / or lower end edge of the locking block. With the lead-in chamfer, the lock is not limited to a predefined position. The ramp-like lead-in geometry can compensate for an offset between the locking window and the locking block. The offset can be a helical offset that runs orthogonal to the locking direction. The lower end edge of the locking block can be positioned higher than a lower edge of the locking window due to the ramp-like lead-in geometry.
[0039] There are embodiments in which the insertion bevel is designed as a circumferential chamfer on the front circumference of the locking block.
[0040] The insertion geometry can be circumferential, allowing the locking block to center itself relative to the deadbolt window regardless of the lock's position. The lock's position can be temporarily or permanently diagonally aligned. The chamfer can be 45° or a different angle. The insertion slope is not limited to a chamfer, but can also be rounded or have another shape.
[0041] There are embodiments in which the lock includes a pre-locking mechanism. The pre-locking mechanism can be an additional lock with a second key. The second key can be a bank key. This can ensure that unauthorized persons who have obtained one of the two keys cannot open the lock.
[0042] The pre-locking mechanism can be an additional bolt located below the bolt block. The bolt block can be blocked by the additional bolt. The additional bolt can be adjusted to a pre-opening position using the second key. In the pre-opening position, the bolt block can no longer be blocked by the additional bolt. The bolt block can then be adjusted from the closed position to the open position using the first key (double-bit key). In an open position, the first key cannot be removed. The first key can be removed as soon as the bolt block is back in the closed position. As soon as the bolt block is back in the closed position, the additional bolt can automatically block the bolt block. The pre-locking mechanism of the lock can be managed by a bank or a safe deposit box provider, for example.The first key is held by the locker owner / user. This arrangement can provide additional security and is referred to as the dual control principle.
[0043] A second aspect of the application relates to a locker insert for accommodation in a slot of a locker arrangement with a lock according to an embodiment of the invention. The locker insert can be a bank safe deposit box insert. The locker insert can have a rectangular cross-section. The locker insert can be connected to the lock. The lock can be an electric hole security lock. The high-security lock in the locker insert can be certified according to DIN EN 1300. The locker insert can have a recess in the area of one end face, which is provided for the lock. The recess can be a locking recess. In the closed position, the locking block can completely penetrate the locking recess. In the open position, the locking block cannot penetrate the locking recess.
[0044] The locker insert can contain both a storage area and the lock. The storage area can be an area for storing valuables. The locker insert can have a keyhole on the side where the lock is located. The locker insert can be inserted into the insertion slot. The locker insert can be inserted into the insertion slot via sliding friction. The insertion slot can be mounted on a separate linear unit. The linear unit can be a pull-out element, for example.
[0045] The width of a locker slot refers to the external dimensions of the locker slot. The width of the locker slot can be the sum of the lock frame width and the wall thickness of the locker slot. The wall thickness can be one or two times the material thickness of a side wall of the locker slot. The lock frame width can extend along the locking direction. The width of the locker slot can be the same as the lock frame width. The width of the locker slot can be further reduced to accommodate lock miniaturization. The locker slot can include a bolt recess in the area of the locking block for the bolt block to pass through. The width and height of the insertion shaft can be slightly larger than the width and height of the locker slot. The width of the locker slot can be between 90 mm and 100 mm.More precisely, the width can be between 94.6 mm and 96.6 mm. More precisely, the width can be 94.6 mm. With this width, one or more 2.5-inch and 1.8-inch hard drives can be stored in the locker compartment. The locker compartment's volume can be between 1 and 2 liters, or more precisely, between 1.2 and 1.8 liters.
[0046] The base body of the locker insert can be made of bent sheet metal, the corners of which can be welded in the bent state. The locker insert can have a lined bottom area. This lined bottom area can serve to protect valuables. The lined bottom area can be made of leather, fabric, velvet, or other material.
[0047] There are embodiments in which an insertion end of the locker insert has a tapered section formed on both sides of the drawer.
[0048] The tapered section can have a chamfered or rounded geometry. The tapered section can serve as a centering aid or insertion aid. The tapered section allows the locker insert to be inserted more easily into the insertion slot. Additionally, the tapered section can stabilize the locker insert. The tapered section can connect the side wall and a rear wall of the locker insert.
[0049] A rear section of the locker insert can additionally include a roof element in the area of the tapered section. The roof element can stabilize the locker insert and protect it against wear.
[0050] There are embodiments in which the locker drawer comprises a front panel, with the lock arranged behind the front panel. The lock can be arranged behind a front wall of the locker drawer and the front panel.
[0051] The front panel can conceal the lock. A keyhole can be provided on the front panel. The keyhole can be a recess in the front panel. The front panel can provide additional protection for the locker drawer and the lock. This can improve burglary protection.
[0052] There are embodiments in which the front plate (60) is larger than a width of the locker insert (50). The front plate can be slightly larger than a front side of the locker insert. This allows the locker insert to be additionally protected against burglary tools. A third aspect of the application relates to a locker arrangement with a plurality of insert slots for receiving a plurality of locker inserts according to an embodiment of the invention, wherein the insert slots are formed by vertical and horizontal dividers, vertical side plates, and horizontal base and cover plates, and the vertical dividers and side plates are each designed as a locking plate and corresponding locking recesses serve to receive the locking block in its closed position, wherein the thickness of the dividers and / or side plates does not fall below the locking length.
[0053] The locker layout can be a bank safe deposit box arrangement. The locker layout can consist of vertical columns and horizontal rows. The number of columns and rows can be varied depending on space requirements and customer layout. The variation does not affect the lock or the locker insert.
[0054] The locking recess can be designed as a through hole. The locking recess can correspond in its geometry to the geometry of the locking block. The locking recess can be rectangular. The locking recess can be used to lock the locker insert with the lock against horizontal displacement out of the insertion slot. In the closed position, the locking block of the lock can at least partially penetrate the locking recess.
[0055] The locker insert can be inserted into the locker insert using sliding friction. The locking block can be arranged completely within the lock frame in the open position. The horizontal divider plate and / or the side plate do not have to be thicker than the locking length. The distance between two horizontally adjacent locker inserts can correspond to the thickness of the horizontal divider plate. The distance can be between 2 mm and 10 mm. Advantageously, the distance can be 4 mm. The ratio of distance to locker insert width can be between 1:9 and 1:50. Advantageously, the ratio can be between 1:22.5 and 1:25. Advantageously, the ratio can be 1:23.65.
[0056] This design eliminates the need for an additional cassette in the drawer slot.
[0057] This design allows for a reduced locker width. The minimum width of the locker is limited only by the lock frame width.
[0058] There are embodiments in which the vertical and horizontal dividers are coupled together via receiving slots, forming a slot matrix. The slot matrix can be an arrangement of several flat individual elements. The individual elements can be a sheet metal arrangement. The individual elements can include vertical and horizontal dividers, vertical side plates, horizontal base plates, horizontal cover plates, and / or a rear wall.
[0059] Several insertion slots can be created within the insertion slot matrix. The insertion matrix can be arranged in an outer frame. The insertion matrix can be connected to the outer frame. The outer frame can be an additional frame and / or a wall niche.
[0060] The dividers with slots can be assembled modularly. The vertical and horizontal dividers can interlock so that the ends of the vertical and horizontal dividers are flush with each other. This modular design allows the number of horizontal rows of the insertion slot matrix to be increased without adjusting the horizontal dividers. This reduces the manufacturing costs of the insertion slot matrix.
[0061] There are embodiments in which the insertion slot matrix is stabilized via side, base, cover plates and the rear wall and tabs are formed on the edges of the separating plate, which tabs can be fixed in corresponding recesses and edge cutouts on the side, base, cover plates and / or the rear wall, wherein the fixing in recesses of the rear wall takes place via the tabs formed as locking tabs on the separating plate edges with a deformable bent end, which fixes the rear wall in a position engaging behind the recess between the bent end and the edge of the separating plate in a form-fitting manner.
[0062] The tabs can be positioned in or through the recesses and / or the edge cutouts. Fixation can be achieved by deforming the divider edge tabs. This deformation can be plastic deformation. Fixation can also be achieved by adhesive bonding, screw bonding, bonding, welding, riveting, or other methods.
[0063] There are embodiments in which the tabs are welded with recesses and / or edge cutouts.
[0064] The connection between the tabs and the recesses and / or edge cutouts can be a different connection. A different connection can be, among other things, a screw connection, an adhesive connection, a rivet connection, or a solder connection. Following the exemplary embodiments, a lock will first be explained using Fig. 1, followed by a locker insert and a locker arrangement.
[0065] There are embodiments in which the locking block passes through the locking window in the closed position and protrudes from the locking window by the locking length and is arranged completely inside the lock frame and outside the locking window in the closed position.
[0066] The locking window can be formed as a through-opening in the locking-side side surface of the lock frame. The locking position can be a position reached after the locking tongue has been moved in the closing direction over its maximum possible distance. The closing direction can be the direction in which a locking block is moved out of the lock frame. The locking length can be the length by which the locking block protrudes from the lock frame in the closed position.
[0067] There are versions of the safe deposit box insert with a lock in the insert. The lock can be mechanical, semi-electric, or electric, especially a lock with pre-locking (bank lock with dual-control principle). Double-bit locks are common among mechanical locks. Dual-control principle locking can be implemented using two locks or a lock with multiple locking levels accessible through a keyhole. The lock can have a longer or extended locking block. The locking length of such a locking block protruding from the lock frame can be equal to or greater than a locking distance—the distance by which the locking block is adjusted when locking / unlocking. This allows for other usage variants. For example, a locking section or locking length can be 14.5 mm and a locking distance 12 mm.This can be a locker insert with a lock for insertion into a drawer slot of a locker arrangement. In such an arrangement, lockable doors or flaps are not required, as the insert itself is lockable.
[0068] Fig. 1 shows a plan view of a lock 1 according to the invention with a locking tongue 7 with a locking block 9 in an open position O and a closed position C. An upper illustration shows the lock 1 in the open position O. A lower illustration shows the lock 1 in a closed position C.
[0069] The lock 1 has a rectangular, trough-shaped lock frame 3 as an outer housing. The lock 1 is aligned such that the two longer side surfaces of the trough-shaped lock frame 3 are horizontally aligned. A vertical side surface is formed as the locking-side side surface 13. A rectangular locking window 15 is formed as a recess in the locking-side side surface 13. A lock mechanism 5 is arranged in the lock frame 3. The lock mechanism 5 comprises the locking tongue 7. The locking tongue 7 is designed in one piece. The locking block 9 is formed on the locking tongue 7 on the side of the locking-side side surface 13. An outer geometry of the locking block 9 is rectangular and corresponds to the rectangular geometry of the locking window 15. A circumferential bevel-shaped introduction geometry 19 is formed on a front edge of the locking block 9.The front side of the locking block 9 is aligned parallel to the locking side surface 13.
[0070] The locking tongue 7 is movable along a closing direction D. The closing direction D runs orthogonally to the locking window 15. The locking tongue 7 can be moved along the closing direction D using a key bit of a key. In the open position O, there is a gap between the front side of the locking block 9 and an inner side surface of the locking-side side surface 13.
[0071] When adjusting from an open position O to a closed position C, the locking block 9 is partially moved out of the locking window 15 via the locking tongue 7 along the closing direction D. A section of the locking window 15 that projects beyond an outer side surface of the locking-side side surface 13 is the locking section 11. A length of the locking section 11 is a locking length L. A total travel path of the locking tongue 7 is a closing distance S. In Fig. 1, the closing distance S of the locking tongue 7 is longer than the locking length L of the locking section.
[0072] In the area of the lower horizontal side surface of the lock 1, a partially visible pre-locking mechanism 21 is arranged below the locking tongue 7. The pre-locking mechanism 21 comprises a wedge-shaped element which, in the closed position C, blocks the locking tongue 7 from being adjusted into the open position O along the closing direction D. In the open position O, the adjustment of the locking tongue 7 along the closing direction D is not blocked. A non-visible part of the pre-locking mechanism 21 is arranged below the lock mechanism 5 and is concealed by the lock mechanism 5.

[0075] Fig. 4a shows a perspective view of a locker insert 50 according to the invention. The locker insert 50 has a rectangular basic shape. The tub shape of the locker insert 50 is composed of a base plate 56, two side walls 54, a rear wall 58, and a front wall 57 with a front plate 60. The front plate 60 is an additional cover that is slightly larger than the width of the locker insert 50 to protect against break-ins. The front plate 60 protrudes beyond the side walls 54 of the locker insert 50. The lock 1 is attached to one end of the insert within the locker insert 50 between the two side walls 54 and behind the front wall 57 and the front plate 60. A keyhole 60a is formed on the front plate 60. The lock 1 in the locker insert 50 is adjusted with the key through the keyhole 60a between the closed position C and the open position O.A trapezoidal tapered section 52 is formed at the other insertion end. A cover plate 62 is partially attached in the area of the tapered section 52. The cover plate 62 rests on the side walls 54 and the rear wall 58 and additionally connects them.
[0076] In contrast to Fig. 4a, Fig. 4b shows the locker insert 50 in an exploded view before the lock 1 is installed in the locker insert 50. The lock 1 fits flush between the two side walls 54. The locking block 9 of the lock 1 is aligned with one of the two side walls 54. A locking recess 53 is formed on the side wall 54 of the locking block 9. The locking recess 53 is open in the upper region of the locker insert 50. When the lock 1 is installed, the locking block 9, in a closed position C of the lock 1, penetrates the side wall 54 in the region of the locking recess 53. A keyhole recess 50a is formed on the front wall 57. The keyhole recess 50a has a substantially identical geometry to the keyhole 60a of the front panel 60. During assembly, the front wall 57 is completely covered by the front panel 60

The locker inserts 50 are surrounded by an outer frame 150. A key is inserted into a lock 1 of the locker inserts 50. The key inserted in the lock 1 completely penetrates the keyhole 60a and the keyhole recess 50a.
[0078] Fig. 6a shows a perspective view of a slot matrix 102. The cube-shaped slot matrix 102 comprises 18 slots 101 arranged in a checkerboard pattern. The slot matrix 102 is formed by two vertical dividers 103 and five horizontal dividers 105. The dividers 103, 105 are framed by two side plates 107, a base plate 109, and a cover plate 111. The slots 101 are open on one side and closed on the other side by a rear wall 112.
[0079] The vertical dividers 103 and the vertical side plates 107 comprise a plurality of locking recesses 113. The locking recesses 113 are rectangular. The locking recesses 113 are arranged in the open side area. The locking recesses 113 are arranged such that at least one locking recess 113 is arranged in each insertion slot 101.
[0080] Fig. 6b shows an exploded view of the insertion slot matrix 102 prior to assembly. Several stacked horizontal sheets 105, 109, 111 and several stacked vertical sheets 103, 107 and a rear wall 112 are shown. The horizontal sheets 105, 109, 111 are arranged orthogonally to the vertical sheets 103, 107. The horizontal and vertical sheets 103, 105, 107, 109, 111 are arranged orthogonally to the rear wall 112. The horizontal sheets 105, 109, 111 each have two receiving slots 106, which have a length that is shorter than the side length of the horizontal sheets 105, 109, 111. The two receiving slots 106 divide the horizontal sheets 105, 109, 111 into three identical sections.
[0081] The vertical dividers 103 in Fig. 6b each have five receiving slots 104, which divide the vertical divider 103 into six identical sections. The receiving slots 104 have a length that is shorter than one side length of the vertical dividers 107.
