Definitions

  • the present invention relates generally to a lock arrangement and more specifically to a motor lock arrangement that includes a motor for driving the mechanical components of the lock arrangement.
  • Some known locks include a lock post and a lock box that can be connected detachably to the lock post and that houses the lock mechanism. This makes possible relatively rational handling of specific products.
  • An example of one such solution is found, for instance, in Swedish Patent Specification SE7601429-9 in the name of GKN-Stenman AB.
  • the components of a motor lock such as an electric motor or some other motor, door position sensors and other types of sensor, cabling, mechanical coupling to followers, etc., have been tailor-made in accordance with requirements and the space available in the lock housing. This results in a large number of different components that can contribute towards high costs and also to impaired mechanical and electrical reliability.
  • One object of the present invention is to provide a lock arrangement of the kind mentioned in the introduction that is suited for automated manufacture with simplified storage and that also fulfils high reliability demands.
  • the invention is based on the insight that a motor lock can be manufactured from modules, of which one consists of a motor unit having mechanical and electrical coupling to other lock units.
  • the motor unit and the lock arrangement according to the invention avoid the aforesaid drawbacks of known techniques.
  • the inventive lock arrangement includes a motor unit as an independent unit. This enables the lock arrangement to be modularised, thereby requiring fewer parts to be stored and/or a greater variation of lock arrangements to be offered.
  • a motor unit includes a printed circuit board or card which carries control electronics, sensors, etc., wherein a sensor is mounted on a part of the circuit board that is intended to be separated from the remainder of the board, preferably with the aid of a fracture indication.
  • a cable arrangement connects the sensor and remaining electronic devices.
  • Fig. 1 is a perspective, exploded overview of an inventive lock arrangement
  • Figs. 2a-c are perspective and plan views of a first embodiment of a motor unit intended to be mounted in the inventive lock arrangement;
  • Fig. 2d illustrates the motor unit of Figs. 2a-c mounted in position in said lock arrangement
  • Fig. 2e is a perspective view of a mounting element for mounting a sensor included in the motor unit shown in Figs. 2a-c;
  • Fig. 2f shows the mounting element together with the sensor
  • Figs. 3a and 3b are respective perspective and plan views of a second embodiment of a motor unit intended to be mounted in the inventive lock arrangement.
  • Fig. 1 shows the lock arrangement in perspective with the box and covering lid removed.
  • the lock arrangement includes a post unit 10, which includes a lock post 11 and a bar or beam 12 of U-shaped cross-section welded to the lock post.
  • the U-bar surrounds all lock functions close to the front of the lock, such as the function of controlling and driving a falling latch 13 and a holding bolt 14.
  • the lock post 11 includes a through-penetrating upper sensor opening 11a. This opening is intended to accommodate a door position sensor in a first embodiment of a motor module according to the invention, as described hereinafter with reference to Figs. 2e and 2f.
  • the lock post also includes a lower sensor opening 11a which is intended to accommodate a door position sensor in a second embodiment of a motor module, which is described below with reference to Figs. 3a and 3b.
  • the lock arrangement also includes a housing that comprises a box 21 and a covering lid 22. These parts are a mirror image of each other, although they are identical in other respects. These parts are fitted to the U-bar 12 by means of fastener elements which in the illustrated case have the form of screws and nut sleeves 24a, 24b that extend through holes 23a-d in the covering lid and through corresponding holes in the box. The holes 23a and 23b register with through penetrating holes 12a, 12b in the post unit.
  • the box and the covering lid also include respective ledges 21a-c and 22a-c that extend at right angles to the bottom and the lid and that function as side surfaces in the assembled state of the lock arrangement.
  • the lock arrangement includes follower units or follower modules, in the illustrated embodiment a cylinder follower unit 30 and a handle follower unit 40.
  • the follower units are mounted between the box 21 and the covering lid 22 and are provided, to this end, with through-penetrating holes that register with the holes 23c and 23d in the covering lid 22 and corresponding pins in the box.
  • the cylinder follower unit 30 is essentially square and includes the drive arrangement typically found in cylinder followers.
  • the unit 30 includes a through penetrating opening 3 1 adapted to receive a dogging element (not shown) in a lock cylinder or a lock knob/handle.
  • the cylinder follower unit 30 is adapted to communicate with the holding bolt 14 via a pin 32 and a link arrangement 14a.
  • the pin 32 is moved either upwards or downwards depending on the rotational direction of the follower, and movement of the pin therewith rotates the bolt 14 between its extended position shown in the figures and a retracted position (not shown).
  • the handle follower unit 40 is adapted to communicate with an arm (not shown) that controls movement of the falling latch 13 between an outwardly extended and inwardly withdrawn position. There is used in this regard a pressure rod 42 of appropriate length.
  • the handle follower is caused to rotate by means of a handle (not shown) that has a square pin or peg inserted in a square opening 41 in the handle follower.
  • the handle follower unit 40 includes an arrangement, which urges the pressure rod 42 to the left in the figure as the handle follower is rotated clockwise as seen in the figure. This causes the arm (not shown) to rotate and forcibly guide the falling latch to its inwardly withdrawn position (not shown).
  • the spring-loaded handle follower is caused to return to its starting position, the falling latch, which is also spring-loaded, returns to its outwardly extended position.
  • the motor unit generally referenced 50, includes a box 51 that has an electric motor 52 disposed therein; see the perspective view of Fig. 2a.
  • the box also houses a printed circuit board or card 53.
  • the printed circuit board includes an electronic circuit arrangement 54 having control and drive electronics for the motor 52.
  • a gearwheel arrangement 55 which includes gearwheels driven by the motor 52 is adapted to move a connecting part 56 up and down in the lock housing.
  • the connecting part 56 is provided with two pinholes and can thereby be connected to a co-acting part of the cylinder follower unit 30; see Fig. 2d.
  • the holding bolt 14 can be manoeuvred in this way by means of the motor 52, which is a characteristic feature of a so-called motor lock.
  • FIG. 2a and 2c An alternative placement of the connecting part is shown in dotted lines in Figs. 2a and 2c and is referenced 56'. This placement may be used, for instance, when the motor unit is used in lock arrangements that have a very small back set.
  • the motor unit shown in Figs. 2a-d includes a sensor 57 which functions as a door position sensor in a known manner.
  • the sensor is placed on an outwardly projecting part or tongue 53a on the circuit board 53.
  • this tongue includes a fracture indication 53b that enables the outward part 53a of said tongue to be separated from the remainder of the circuit board.
  • the motor module 50 also includes a cable arrangement 58 adapted to connect the sensor 57 to the control electronics 54, as apparent from the perspective view of Fig. 2b. This is necessary, since that part on which the sensor 57 is arranged is removed from the remainder of the circuit board 53.
  • the cable arrangement 58 Prior to fitting the motor module, the cable arrangement 58 is disposed in a cable depot in the unit and a required amount of cable is withdrawn from the depot when mounting the motor module. That part of the cable arrangement 58 placed in the depot is shown in broken lines in Fig. 2b.
  • Fig. 2c is a plan view of the motor unit prior to mounting said unit
  • Fig. 2d is a plan view of the motor unit fitted in a lock housing.
  • Fig. 2e shows a mounting element 60 for mounting the sensor 57 in the upper sensor opening 1 1a in the lock post, as shown in Fig. 1.
  • the mounting element is made of a plastic material and has a flat end surface 61 and a barrel surface 62 whose shape harmonises with the shape of the upper opening 11a in the lock post 11; see Fig. 1.
  • the mounting element also includes two barbed spring arms 63 which are adapted to retain the mounting element in the opening 1 la subsequent to having inserted said element.
  • the sensor-equipped part 53a When mounting the sensor, the sensor-equipped part 53a is broken off from the remainder of the circuit board and the desired amount of cable is withdrawn from the cable depot.
  • the sensor carrying part 53a is then inserted through the opening 11 a in the lock post from the inside and then placed in the mounting element 60. This is then inserted into the opening 1 la from the outside until the barbed arms 63 engage the inner surface of the lock post, therewith holding the mounting element in place.
  • the mounting element can then only be released by actuation of the arms 63 from inside the lock housing.
  • the sensor-provided part 53a is held in place in said element, and hence the sensor 57 obtains a predetermined position in the opening 1 1a.
  • the motor unit 50 can thus be used with lock housings of different designs, since the sensor can be placed in a desired position in said housing. This provides a flexible solution with regard to positioning of the sensor, such as a d ⁇ or position sensor, as different applications may require different sensor placements. This advantage is afforded by the fact that part of the circuit board included in the motor unit can be removed.
  • the sensor carrying part 53a of the circuit board is attached to the remainder of said board upon delivery, which affords rational handling and also reduces the risk of damage to the sensor.
  • the sensor carrying part is removed from the remainder of the circuit board and a desired length of cable is withdrawn from the depot. This cable storage also contributes towards the rational and safe handling of the motor unit.
  • FIG. 3a and 3b illustrate the motor unit in perspective and in plan respectively.
  • the motor unit illustrated in Figs. 3a and 3b is, to a large extent, similar to the motor unit described above with reference to Figs. 2a-d.
  • the unit includes a box 151 in which there is arranged an electric motor 152.
  • a circuit board 153 is mounted in the box.
  • This circuit board includes an electronic circuit arrangement 154 comprising motor control and motor drive electronics.
  • a gearwheel arrangement 155 includes gearwheels, which are driven by the motor 152 and arranged in the same way as in the aforedescribed embodiment.
  • the circuit board 153 includes an outwardly protruding part 153a having parallel-coupled magnet sensors 157, 157' coupled to the circuit arrangement 154 disposed on the circuit board.
  • the outwardly protruding part 153a of the circuit board is provided with a number of fracture indications, of which one 153b has been shown in broken lines in Figs. 3a and 3b.
  • the fracture indications are adapted to different standard back-set measurements and the motor unit is adapted to the back set concerned by simply breaking off the circuit board at an appropriate fracture indication. Because the circuit board is provided with several magnet sensors 157, 157' - one at each fracture indication - a functioning magnet sensor will always be present at the tip of the circuit board part 153a.
  • the advantages afforded by said first embodiment are also obtained with the second embodiment.
  • Fig. 2f mounting of the sensor shown in Fig. 2f can be effected in a way other than with the aid of the illustrated mounting element.
  • the sensor part 53 a (and 153 a) can be attached in a desired position with the aid of glue or some other adhesive, for example.
  • the sensor may be placed on the circuit board 53a in a manner which enables the sensor, similar to the second embodiment, also to be used without removing the sensor carrying part 53a from the remainder of the circuit board.

Abstract

L'invention concerne un bloc moteur destiné à être monté dans un système de verrouillage et comprenant un moteur électrique (52), une carte à circuits imprimés (53) contenant un ensemble circuit électronique (54) destiné à la commande du moteur, un détecteur (57) monté sur la carte à circuits imprimés et électriquement relié à l'ensemble circuit électronique, et un système de couplage mécanique consécutif (55, 56). Ces composants sont logés dans un boîtier (51) qui constitue une unité distincte pouvant être montée dans une gaine de serrure. A cet effet, le détecteur et/ou le système de couplage mécanique ont au moins des deux positions d'emplacement potentielles. Le détecteur est, de préférence, monté sur une partie (53a) de la carte à circuits imprimés et peut être retiré du reste de la carte à circuits imprimés. L'installation d'un bloc moteur séparé permet de modulariser le système de verrouillage et donc de stocker un plus petit nombre de pièces nécessaires et/ou d'offrir un plus grand éventail de systèmes de verrouillage qu'actuellement. On obtient également une meilleure fiabilité électrique et mécanique.
