Definitions

• the invention relates to a device for locking and unlocking the cover of a cash register-controlled cash drawer according to the preamble of claim 1.
• Cash drawers at cash registers are often designed as hinged lid drawers that are separate from the cash register housing and have a lid that is controlled by the cash register. During a registration process, this lid is automatically opened by a command entered into the cash register by the cashier and is closed again automatically or manually after the cashier process.
• the electrical connection between the cash register and the cash drawer takes place via a base part which is electrically coupled to the cash register and onto which the cash drawer is placed. After business hours, the cash drawer can be removed from the base part and transported to a cash register, the cash drawer also being released electrically from the cash register.
• a lock is generally provided which allows the cover to be unlocked or locked again by means of a key.
• a cash register-controlled cash drawer is already known from EP-A-0 560 292, which has the aforementioned properties.
• a locking element is provided which inevitably comes into engagement with the closing element when the cash drawer is placed on the base part and locks it in its inactive position.
• the disadvantage of this construction is the high construction effort and the associated costs.
• the task is solved in that the key channel of the lock is covered when the cash drawer is placed on the base part.
• the lock When the cash drawer is removed from the base part, the lock is accessible so that the key can be inserted into the key channel and the lid can thus be opened. However, if the cash drawer is placed on the base part, the lock is covered so that a key cannot be inserted into it. This prevents the lid from being opened with the key in the operating position of the cash drawer. There is practically no additional mechanical effort, because a lock was also already available, only its locking element has to be adapted to the design of the bolt.
• the lock is preferably built into a wall of the cash drawer housing, which is covered by the base part or another object located directly at the location of the cash drawer, such as, for example, a part of the cash desk on which the cash drawer is placed.
• the bottom wall of the cash drawer housing is particularly suitable for installing the lock, because this is covered by the base part anyway when the cash drawer is in the operating position. With an appropriate arrangement of a protrusion covering the lock on the base part, this can Lock can also be installed in any other wall of the cash drawer housing 4.
• the lock is a cylinder lock that can be actuated by a key.
• Such locks offer a high level of security against unauthorized opening with objects other than the associated key.
• a locking element can be attached particularly easily to such a lock and finally such locks are available with different locking authorizations. It is particularly advantageous to design the lock so that the key can be removed from the lock only in one position of the lock, in which the locking element is in its inactive position. This prevents the cash drawer from being placed on the base part with the lock in the unlocked position.
• 1 is a cash drawer and a base part on which the cash drawer can be placed
• Fig. 2 shows a locking and unlocking device in a schematic representation.
• a cash drawer 2 shown in FIG. 1 essentially consists of a lower cash drawer housing 4 and a cover 8 which is pivotably arranged thereon about a horizontal axis 6.
• money inserts 10 for paper and coin money in a manner known per se.
• a step 14 provided bore 16 which is intended for receiving a cylinder lock 18.
• a cylinder lock 18 is intended for receiving a cylinder lock 18.
• the cylinder lock 18 can be actuated by means of a key 22 (FIG. 2). It allows a mechanical locking of the lid 8 with the cash drawer housing 4 or an unlocking for opening the lid 8.
• the cash drawer 2 can be transported independently of a cash register. For their operational use, they are placed on a base part 24 which is arranged in a fixed position at the cash desk.
• the cash drawer housing 4 has a recess 26 on its underside (FIG. 2) which can accommodate the functional elements 28 of the base part 24.
• These functional elements 28 serve e.g. for centering and holding the cash drawer 2 on the base part 24; in addition, they contain, for example, the cash register-controlled, electrically switchable switching elements explained below with reference to FIG. 2 for adjusting a bolt.
• the base part 24 is electrically connected to a cash register (not shown), so that the switching elements provided on the base part 24 can be actuated by commands entered into the cash register.
• the cash drawer 2 can be locked to the base part 24 by means not shown, in such a way that, for example, it can only be removed by authorized persons.
• Fig. 2 shows a fragment of the cash drawer 2 with the lid 8 open.
• the cylinder lock 18 is installed, which can be actuated by means of the key 22.
• a shaft 30 is arranged axially on the locking cylinder of the cylinder lock 18, and an eccentric locking element 32 projecting radially therefrom is attached to the free end of the shaft 30. It is about the axis 34 of the cylinder lock 18 between one with solid lines shown active position and an inactive position shown in dashed lines pivotable.
• a bolt 36 is arranged in the cash drawer housing 4 in the direction of an arrow 38.
• a locking hook 42 is formed which, when the cover 8 is locked with the cash drawer housing 4, can engage behind a locking lug 44 which is arranged on the inside of the front wall 40 of the cover 8.
• the latch 36 is biased in the direction of its locking position by a return spring 46 designed as a compression spring, so that it must be pressed into its unlocking position (shown in FIG. 2) against the force of the return spring 46 in its locked position. locking position but is provided by the return spring 46.
• a return spring 46 designed as a compression spring
• a switching element 50 which can be switched electrically, for example by a solenoid drive 48, is provided, which engages in a recess 52 formed on the upper side of the latch 36.
• the latch 36 can also be moved by the switching element 50 into its unlocking position shown in FIG. 2.
• the cylinder lock 18 With the cash drawer 2 removed from the base part 24 (FIG. 1), the cylinder lock 18 is accessible, so that the key 22 can be inserted into the locking cylinder and the cover 8 can thus be opened. If, on the other hand, the cash drawer is placed on the base part 24 in the direction of the arrow 54 in FIG. 1, a projection 25 arranged thereon covers the cylinder lock 18, so that a key cannot be inserted into it. In order to the lid 8 is prevented from opening with the key 22 in the operating position of the cash drawer 2.
• the cylinder lock 18 can also be installed in any other wall of the cash drawer housing 4 become.
