Description of Embodiments
[0016] A first embodiment of the control device according to the invention for the adjustment of a lock is seen in Figure 1 a. The control device is intended to be mounted on the inside of a door or a window or in another comparable suitable application, and accordingly be provided with a suitable handle 51 and knob 52, see Figure 1 b. Included details are formed in such a way that the control device can be mounted in already existing holes in a door that is equipped with module locks (mechanical lock housings) of the type ASSA 565 (ASSA is a trademark). After such a mounting of the control device, the door will externally - with an occurring external handle and lock cylinder in an external cylinder protection - look exactly the same as before the mounting of the control device, which is a great advantage that applies to all embodiments of the control device. Accordingly, it will not be possible to externally distinguish a door having the control device from a door that lacks such equipment.
[0017] In the control device, a source of power 1 in the form of three batteries is found, but the number of batteries may naturally vary. The source of power 1 is included in an electronic circuit together with a switch 34, at least one means 35 for the receipt and evaluation of a wireless signal and for possible actuation of at least one device 40 for the conversion of electric energy into mechanical motion. The switch 34 is a micro switch 34, but the type of switch may naturally vary. The means 35 in the embodiment illustrated consists of two printed circuit cards 35 of the PCB type mounted in a printed circuit card holder 19, but the number of printed circuit cards and the type of the same may naturally vary. The device 40 in the embodiment illustrated is one piezo motor 40, but the number of mechanisms and the type of the same may naturally vary.
[0018] The micro switch 34 may be actuated mechanically by a lock plate 2 that in turn is rotatable around a first axis of rotation 55 that extends essentially perpendicularly to the principal extension plane of the lock plate 2. The axis of rotation 55 coincides with an axis of rotation of the handle 51 - here denominated first lock rotation axis - and the lock plate 2 is connected to the handle 51.
[0019] At least one first card 35 of the printed circuit cards 35 is adapted to wireless communication with a mobile telephone or the like, and at least one second card of the printed circuit cards 35 is adapted to - in the event of a wireless signal evaluated and approved by said first card - open an electric connection between the batteries 1 and the piezo motor 40, alternatively enable such an opening. The piezo motor 40 is mechanically connected with at least one first link 17 in the form of a catch 17 provided with at least one first mechanical engagement member in the form of a bulging that, in the engaged state, co-operates with at least one second mechanical engagement member in the form of a corresponding indentation of at least one second link 7 in the form of a gear segment 7 for direct or indirect transfer of rotary motion from said first axis of rotation 55 to a second axis of rotation 56. In the engaged state, the gear segment 7 is rotatable around said first axis of rotation 55. According to the present embodiment, the transfer of rotary motion from the first axis of rotation 55 to the second axis of rotation 56 is effected indirectly in such a way that the gear segment 7 actuates an intermediate gearwheel that in turn actuates a gearwheel that turns around the axis of rotation 56. The axis of rotation 56 coincides with an axis of rotation of the knob 52 - here denominated second lock rotation axis.
[0020] According to a second embodiment of the control device according to the invention, included details are instead formed in such a way that the control device can be mounted in already existing holes in a door that is equipped with module locks (mechanical lock housings) of the type ASSA 2000 (ASSA is a trademark), see Figures 2a and 2b. In this case, on the inside of the door, in addition to a handle 51 and a knob 52, there is also found a lock cylinder 54 in a cylinder protection. Please observe that the reference designations in Figure 2a regarding the second embodiment do not entirely correspond with those in Figure 1 a regarding the first embodiment, see pages 11-13.
[0021] According to a third embodiment of the control device according to the invention, included details are formed in such a way that the control device can be mounted in already existing holes in a door that is equipped with module locks (mechanical lock housings) of the type ASSA 565 (ASSA is a trademark), see Figures 13a and 13b. A part of the construction in the mounted state is seen in Figure 14. A first printed circuit card 349 of the PCB type for the wireless communication is present and accordingly corresponds to said first card of the printed circuit cards 35 according to the first embodiment. Together, corresponding to the switch 34 according to the first embodiment - and, accordingly, instead of micro switches - there is found, according to the third embodiment, an IR cell (infrared cell) in combination with an accelerometer, both of which are mounted on a second printed circuit card 350 of the PCB type corresponding to said second card of the printed circuit cards 35 according to the first embodiment. The IR cell has the ability to transmit a light beam for the detection of whether an occurring lock catch of an occurring first link is in an initial position or in an upper active position, i.e., whether an occurring first mechanical engagement member is in a disconnected initial position or in a connected active position in relation to occurring other engagement members of an occurring second link. The accelerometer has the ability to sense the motions of a handle. The second printed circuit card 350 is in turn mounted on a lock plate 303 corresponding to the lock plate 2 according to the first embodiment. The first printed circuit card 349 and the second printed circuit card 350 may - instead of constituting two separate printed circuit cards - be combined in one and the same printed circuit card, and accordingly constitute two card parts in a single printed circuit card. Instead of an IR cell in combination with an accelerometer, only an IR cell may be used, i.e., it is feasible to spare the accelerometer and still obtain an acceptable function in the use of the control device. Please observe that the reference designations in Figure 13a regarding the third embodiment do not entirely correspond with those in Figure 1a regarding the first embodiment or Figure 2a regarding the second embodiment. Of course, additional embodiments of a control device according to the invention are also feasible without deviating from the general idea of the invention. The designs according to all embodiments can be mirror-inverted for other types of doors and/or windows.
