Abstract
Description
The invention provides an actuating device, particularly for opening and closing, e.g., a lock that facilitates access to protected areas. In particular, it relates to so-called smart locks where opening or closing can be carried out without direct contact between the authorized person and the lock. Known actuating devices for opening and closing a lock that facilitate access to protected areas have an actuating assembly for operating the lock located within a housing shaped like a sleeve and secured from the outside by a cover and from the other side by a base fixed to the lock, in which base the elements of the actuating assembly are fixed or integrated. The actuating assembly comprises a power source, an electric motor, and a set of transmission gears. The power source consists of four cylindrical primary cells (batteries) located adjacent to the motor and parallel to its geometric axis, to energize the electric motor. The drive of the electric motor is transferred, through the transmission gear set comprising toothed wheels, to an element that can be manipulated to control the lock. The base has an opening and the lock control element passes through it, while the other end of the element is coupled to the lock mechanism. The bushing that forms the housing of the drive device has teeth on its inner side that mesh with one of the gears in the drive assembly's transmission gear set. The drive device has an electronic control unit that manages the drive assembly. The electronic control unit is powered by batteries housed inside the casing. The electronic control unit can be controlled wirelessly by a computer program, preferably a mobile application, via a wireless connection. The device does not require an external power source and can be managed using a smartphone application. The actuating device is mounted from inside the lock housing, on all types of doors with a low-profile (non-standard) cylinder. The actuating device for opening and closing a lock constructed in this way is quite large due to the size of the power supply batteries and the size of the remaining components of the actuating mechanism that must be housed within the device casing. It requires a low-profile cylinder to facilitate proper mounting of the device base. A lock actuating device is known from Polish patent application P.336314. The actuating device, mounted on a door and comprising a decorative plate, is intended for the motorized and manual activation of a locking cylinder. It has a drive shaft for transferring rotational motion to the locking cylinder, a knob for manual rotation of the drive shaft, and, located on the knob, a geared motor for motorized rotation of the drive shaft. A fixed gear wheel is mounted on the drive shaft, remains engaged with the knob, and transfers the rotational motion. The geared motor is connected so that it does not rotate with the decorative plate and is engaged in a state such that it drives the gear wheel by means of a clutch. A device for opening and closing access to protected areas is known from German patent application DE 102014009826 A1. The device has a cylindrical housing. The housing contains a base plate, a miniature motor (preferably a DC motor), a battery, a locking mechanism, and a control unit. The locking element of the locking mechanism is a rod with a movable crown driven by the electric motor and a torsion spring capable of transferring the motor's motion to the rod. The battery must supply power to the control unit independently of the external power supply. The control unit is operated wirelessly. A device for opening and closing a door lock is known from Polish patent application P.421767. This actuating device comprises a drive assembly consisting of a power source, an electric motor, and a transmission gear set terminating in a toothed wheel located within a rotating housing. The lock comprises a body in which a lock control element is rotatably mounted. The housing is mounted on the lock body by means of a control element to which it is fixedly connected. The actuating device has a toothed ring that cooperates with a toothed wheel of the drive assembly, which is rotatably mounted on the housing by means of a bearing. The ring is coaxial with the rotating housing and fixed with respect to the lock body.From the lock side, the crown has a protrusion that fits into an opening made respectively in the lock housing. Based on Polish application P.421765, a drive device for opening and closing a lock that facilitates access to protected areas is known. The device comprises, within a housing: a set of transmission gears, at least one electrical power source in a protective housing, and a drive motor that transfers the drive to a control element of the lock's rotary mechanism by means of a set of transmission gears. The lock comprises a body in which the control element is rotatably mounted. The drive device has a base, fixed relative to the lock, on which the following elements are fixedly mounted: a set of transmission gears, at least one electrical power source, and a drive motor.The control element of the lock mechanism is seated on a toothed wheel that is one of the wheels of the transmission gear assembly, and the housing has a bushing shape seated by bearing on the base and has on its inner side a toothed section that meshes with the toothed wheel of the transmission gear assembly, where the lock mechanism element is seated. The objective of the invention is to develop a new actuating device for closing and opening a simple lock, said device being applicable to existing door locks, in particular, without the need to modify their construction, and to provide a new type of solution.

In the embodiments of the invention shown in Figure 1, Figure 2, and Figure 6, the lock comprises a conventional profiled cylinder 2 mounted, for example, on a door leaf, where the lock cylinder, which facilitates access to the protected areas, comprises a body 6 in which the control element 7 of the lock cylinder 2 is housed. The control element 7 of the lock cylinder 2 can rotate within the body 6 of the lock cylinder 2, but cannot move relative to it along the longitudinal geometric axis of the body 6 of the lock cylinder 2. Obviously, lock cylinder 2 can be an element of any lock that facilitates access to protected areas and comprises the elements mentioned above. As shown in Figure 1, Figure 2, and Figure 6, in embodiments of the invention, an actuating device 1, particularly for closing and opening a lock cylinder 2, comprises a housing 3 in which an actuating assembly is accommodated (not shown). The actuating assembly comprises, in the first embodiment shown in Figure 1, Figure 2, and Figure 6, at least one drive motor and a gear transmission with a terminal gear 4, the gear 4 being the terminal element of the gear transmission of the drive assembly cooperating with a ring gear 5 comprising internal teeth 9 (as shown in Figure 2 and Figure 6) such that when it rotates during operation of the drive motor 1, this gear meshes with the internal teeth 9 of the ring gear 5. The toothed ring 5 is mounted coaxially and rotatably with respect to the housing 3 of the actuating device 1 for closing and opening a lock. The toothed ring 5, after mounting the toothed ring 2 in the lock, surrounds, at least partially, the body 6 of the cylinder 2 and comprises means for facilitating the fixed mounting of the toothed ring 5 in the body 6 of the lock cylinder 2. Figures 3a and 3b show means for mounting the toothed ring 5 on the body 6 of the lock cylinder 2 in the first embodiment. For this purpose, the toothed ring 5 has, on the side opposite the housing 3, a mounting portion 51 comprising three threaded mounting holes 52 extending radially into the mounting portion 51 of the toothed ring 5. The mounting holes 52 are through holes, and a fixing screw 53 is inserted into each mounting hole 52. When the actuating device 1 is mounted on the lock cylinder 2, the mounting portion 51 of the toothed ring 5 partially surrounds a terminal portion of the body 6 of the cylinder 2, while leaving only a lower portion of the body 6 of the lock cylinder 2 unenclosed.For this purpose, the toothed ring 5, on its front outer side in relation to the housing 3 of the drive device 1 in which it is mounted, has a recess 10 that has a cross-section with the shape of the contour of the body 6 of the cylinder 2, as shown in figure 3a. During the assembly of the actuating device 1 into the lock cylinder 2, the recess 10 in the mounting portion 51 of the toothed ring 5 slides onto the end section of the cylinder body 6. Subsequently, the mounting holes 52 are aligned with the cylinder body 6 along its geometric axis. The fixing screws 53 are then tightened so that their pointed ends partially penetrate the cylinder body 6, effectively securing the actuating device 1 to the cylinder body 6. In the embodiment shown in Figure 3a and Figure 3b, the fixing screws 53 are headless bolts, rendering them invisible once the actuating device 1 is mounted to the cylinder body 6. Figure 4a and Figure 4b show means for securing the toothed ring 5 to the body 6 of the lock cylinder 2 in a second embodiment. For this purpose, the toothed ring 5 has, on its side opposite the housing 3, a mounting portion 51 having a cross-section with a shape that surrounds, at least partially, the end portion of the body 6 of the cylinder 2. The mounting portion 51 is partially sectioned radially and comprises at least one transverse opening 54 extending perpendicularly to the plane comprising the longitudinal geometric axis of the toothed ring 5, wherein the transverse opening 54 in the sectioned portion is a through hole and in the solid portion of the mounting portion 51 of the toothed ring 5 is threaded and receives a clamping screw 55. The toothed ring 5, on its front outer side relative to the housing 3 of the drive device 1 to which it is secured, has a recess 10 that has a cross-section shaped like the outline of the body 6 of the cylinder 2, as shown in Figure 4a. During the assembly of the actuating device 1 into the lock cylinder 2, the recess 10 in the mounting portion 51 of the gear 5 slides onto the end section of the cylinder body 6. A clamping screw 55 is then inserted into the transverse opening 54 from its unthreaded side and tightened. This clamps the radially segmented mounting portion 51 of the gear 5, thus effectively securing the gear 5 to the cylinder body 6. Figure 5a and Figure 5b show means for securing the toothed ring 5 to the body 6 of the lock cylinder 2 in a third embodiment. For this purpose, the toothed ring 5 has, from the side opposite the housing 3, a mounting portion 51 having a cross-section with a shape that essentially surrounds, at least partially, the end portion of the body 6 of the cylinder 2. The mounting portion 51 can be disassembled relative to a portion of the toothed ring 5 with teeth 9 and can also be manufactured as described in the first embodiment of the invention and shown in Figure 3a and Figure 3b, or as described in the second embodiment of the invention and shown in Figure 4a and 4b.In this embodiment of the invention, a portion of the toothed ring 5 with teeth 9 and the mounting portion 51 of the ring 5 are coupled by means of two connecting screws 56, and the removable mounting portion 51 is partially sectioned radially and comprises at least one transverse opening 54 extending perpendicularly to the plane comprising the longitudinal geometric axis of the toothed ring 5 through the sectioned portions of the removable mounting portion 51 of the toothed ring 5, wherein the transverse opening 54 in one of the sectioned portions is threaded and receives a clamping screw 55. The body 6 of the lock cylinder 2, in which the control element 7 is seated and can be manipulated to close and open a lock, has a non-circular and non-ruled shape in its cross-section from the side of the actuating device 1, as shown in Figure 1 and Figure 2. In the embodiments of the invention shown in Figure 1 and Figure 2, it is a commercially available conventional cylinder shape that, in its cross-section in the upper portion (in a state mounted on a door leaf), has a circular shape combined with a substantially rectangular shape with a rounded side at the bottom of a width less than the diameter of the circle at the top.Obviously, this embodiment does not exclude the possibility of using the actuating device 1, in particular for closing and opening a lock that facilitates access to protected areas, in other types of locks comprising cylinders with different body shapes. As shown in Figure 6, the housing 3 is mounted by rolling on the toothed ring 5 in a sliding bearing. Obviously, in other embodiments of the invention, the housing 3 may be mounted by rolling on the toothed ring 5 in any manner known in the art, for example, on a ball bearing, a needle bearing, or a roller bearing. In all embodiments of the invention shown in Figure 2, Figure 3b, Figure 4b, Figure 5b and Figure 6, the toothed ring 5 has a toothing 9, which is an internal toothing, although it is obviously possible to use a toothed ring 5 with an external toothing 9 in the construction of the drive device 1 according to the invention. The drive device 1, in particular for closing and opening a lock that facilitates access to protected areas, has an electronic control unit (not shown), housed within a housing 3 and managing a drive assembly in the housing 3 comprising a sensor (not shown) that is an accelerometer, for determining the angular position of the rotating housing 3 relative to the lock cylinder 2. In the presented embodiments of the invention, the drive device 1, in particular for closing and opening a lock that facilitates access to protected areas, is controlled wirelessly by the control unit by means of a computer program, preferably a mobile application, in particular for a smartphone, by means of a wireless link such as Bluetooth. The electronic control unit has an electrical connector, designed to provide a supply voltage and a data transfer 3, located on the rotating part of the housing (not shown). Drive device 1 has a power source that is a primary or secondary cell (not shown). The actuating device 1 is located on the inside side of the entrance to the protected access areas and opposite the key-controlled part of the lock cylinder 2.
