Description

[0001] The invention relates to an electronic lock for doors, compartments and flaps on furniture, cabinet systems and the like. Such locks are used, for example, in locker systems such as those provided in swimming pools and saunas, fitness centers, schools, universities, train stations, companies and the like, or in cabinets in offices, on lockers, compartments, flaps, drawers, etc. Electronic locks have proven themselves in such furniture and cabinet systems because they are very secure. Individual compartments can be accessed via a central module that controls the individual locks, or individually for each compartment. Access authorization is usually granted via an electronic key such as a card, a fob, a smartphone, a wearable, a code, a transponder or even biometric features.

[0002] When assembling cabinet systems or furniture, the furniture itself is often assembled first and the electronic locks are added later. However, the person responsible for installing the locks must then handle the installation inside the compartment using tools such as screwdrivers and the like. All locks must then be installed in all compartments, including compartments that are close to the floor or relatively high up. However, this is cumbersome and can be difficult for an operator, especially if the compartments are relatively small or narrow. If the locks are installed on the compartment walls in advance, there is a risk that they will be stolen before the cabinet system is in operation, especially when installed in public spaces such as train stations, etc.

[0003] A lock commonly used in such cabinet systems is shown, for example, in CN 215520421 U. Here, a plate is attached to the side of the compartment, onto which the lock is then mounted. To protect the lock, a cover plate is then screwed to the lock. In the example shown, this requires five screws, which must then be positioned correctly in the compartment and tightened by an operator. However, this is complex and makes the installation of the locks time-consuming.

[0004] The object of the invention is therefore to avoid the aforementioned disadvantages and to design an electronic locking unit that can be easily installed in an already installed cabinet system or similar piece of furniture or can also be retrofitted to existing cabinet systems or pieces of furniture.

[0005] This object is achieved by the characterising features of claim 1, which have the following particular significance.

[0006] The lock unit according to the invention provides a plate which can be arranged on a side wall of the compartment and to which the lock can be connected in a form-fitting and / or force-fitting manner. The lock itself is pre-assembled in a housing. The lock can then be connected to the plate without the aid of tools, with the lock housing then being held to the plate by a form-fitting and / or force-fitting arrangement. This makes it quick and easy to install the lock on an already assembled piece of furniture or cabinet, even if the compartment in which the lock is to be installed is rather small or narrow. Retrofitting existing cabinets or pieces of furniture with the locks according to the invention is also simple and straightforward.

[0007] Particularly preferably, the housing of the lock can be plugged, clipped and / or slid onto the plate. This makes it very easy to mount the lock on the plate. In a preferred embodiment, the plate has one or more receiving lugs while the housing has one or more openings. To mount the lock on the plate, the housing with its openings can be pushed into the area of ​​the receiving lugs and locked there. The receiving lugs can be elastic and can initially be displaced by the housing during assembly. When they reach the openings, they then move back to their original shape due to their elasticity and penetrate into the opening, locking the housing to the plate.

[0008] Preferably, the plate has a frame within which the lock housing can be arranged. This frame can alternatively or additionally serve to secure the housing to the plate or as a positioning aid for mounting the lock to the plate.

[0009] In order to fasten the panel to the side wall of the compartment, one or more expansion dowels can be provided in a preferred embodiment. These then engage in openings in the side wall of the compartment. The expansion dowels can be eccentric and expand when rotated. At a small angle of rotation of 90°, for example, the dowels can already spread out in a preferred embodiment and hold the panel securely in the side wall of the compartment. This also simplifies the installation of the panel in the compartment. Even when the cupboard system or piece of furniture is already finished, the panel can be installed quickly and easily in the individual compartments. Of course, it is also possible to attach the panel to the side wall of the compartment using a screw connection and / or an adhesive connection and / or bolts or other fastening means.

[0010] It is particularly preferred that the bolt be mounted on the door so that it can be adjusted in height. This allows it to be adjusted even after the lock has been installed so that it can securely engage with the lock, while also compensating for tolerances and installation inaccuracies.

[0011] Furthermore, a mechanical emergency release for the electronic lock can also be provided. This is used, for example, in the event of a power failure or if the lock's battery is dead or there is a defect in the electronic lock. This can then be implemented, for example, via a cable or chain pull, accessible via an inspection hatch on the piece of furniture or cabinet.

[0012] Further advantages and embodiments of the invention are shown in the dependent claims, the following description, and the drawings. The figures illustrate the invention in an exemplary embodiment. They show: Fig. 1: an electronic lock according to the invention with housing in bottom view, Fig. 2: the castle from Fig. 1 in side view, Fig. 3: the castle from Fig. 1 and Fig. 2 in plan view, Fig. 4: a plate according to the invention in bottom view, Fig. 5: the plate from Fig. 4 in side view, Fig. 6: the plate from Fig. 4 and Fig. 5 in plan view, Fig. 7: a locking unit according to the invention in bottom view, Fig. 8: the locking unit Fig. 7 in section along line A from Fig. 7, Fig. 9: the locking unit Fig. 7 and Fig. 8 in plan view, Fig. 10: the castle from Fig. 1 to 3 with latch in bottom view.

[0013] In Fig. 1 to 3, the lock 30 according to the invention is shown with a housing 31. Two openings 32 are visible, which can be used for fastening and locking the housing 31 to the plate 20. The plate 20 is in the Fig. 4 to 6. Here, two receiving tabs 22 can be seen, which can cooperate with the openings 32 on the housing 31 to hold the housing 31 to the plate 20. Furthermore, the plate 20 has a frame 23, which can also serve to hold the housing 31, but also for positioning so that the receiving tabs 22 of the plate 20 can more easily engage the openings 32 of the housing 31.

[0014] Furthermore, two expansion dowels 21 are visible. These are eccentrically designed and expand when rotated. A rotation of approximately 90° is sufficient in this embodiment. This allows for quick and easy installation of the plate 20 on the side wall of the compartment.

[0015] The lock unit 10 with plate 20 and attached lock 30 show the Fig. 7 to 9. The lock 30 is clipped with its housing 31 to the receiving tabs 22 of the plate 20. The receiving tabs 22 are arranged in the openings 32 of the housing 31. The housing 31 itself is additionally encompassed and held by the frame 23 of the plate 20.

[0016] Out of Fig. Figure 10 shows how the lock 30 interacts with a bolt 40 arranged on a door 41. The bolt 40 has penetrated the lock 30 and is in its locked state, so that the contents of the compartment are not accessible.

[0017] Finally, it should be noted that the embodiments presented here are merely exemplary embodiments of the invention. This is not limited to them. Rather, modifications and variations are possible. The type of latching or locking of the housing to the panel can vary. For example, projections can be provided on the housing that snap into recesses in the panel. Any type of latching or clipping can be used here. The invention can be used on any type of electronic lock, for furniture, compartments, flaps, cabinets, drawers, etc. List of reference symbols: 10 Electronic lock unit 20 plates 21 expansion anchors 22 Mounting tab 23 frames 30 Electronic lock 31 housings 32 Opening 40 bars 41 Door QUOTES CONTAINED IN THE DESCRIPTION
