Definitions

  • the present invention relates to a lock.
  • the invention relates, more particularly with locks called “latch bolt”, that is to say, locks including a button which controls the erasure of the bolt in order to release it from the striker to allow opening, the bolt returning to its initial position as soon as released.
  • One of the aims of the present invention is to make a latch lock controlled by a button which avoids the use of a key mechanism and which can only be opened by people allowed.
  • the lock according to the invention is of the type comprising an operating button, a mounted latch bolt sliding and guided in a case against the action of elastic means tending to keep it in a position corresponding to the closing of the lock and a link kinematics interposed between said bolt and the button so that the maneuver of it generates the erasure of the bolt to place it in the open position of the lock, means being interposed between the button and the kinematic connection so that the lock cannot be open only after the button has been operated in several meanings corresponding to a preselected combination, said lock being characterized in that it comprises a sector mounted rotating on an axis of the housing against the action of return means and integral with the button, said sector being mounted sliding on its axis against the action elastic means and comprising a series of cams with which a heel of a connected pusher cooperates, by a kinematic connection, to the bolt, the cams being arranged so that the pusher does not control opening lock only after the button has been pressed following a number of turning, pulling movements
  • the lock cannot be open only after the button has been operated, according to a combination provided in advance.
  • the sector has a groove to return the heel to the position initial closing of the lock.
  • the lock can, according to an alternative embodiment, include means for automatically bringing back the bolt in the closed position after it was cleared when the button was operated in the different meanings corresponding to the combination.
  • the sector cam corresponding to the opening of the lock is terminated by a stop with interposition of a spring, said cam having an inclined opening part in the groove.
  • Figure 1 is a sectional view of a lock, according to the invention.
  • Figure 2 is a sectional view along the line 2-2 of figure 10.
  • Figure 3 is a sectional view along the line 3-3 in Figure 10.
  • Figure 4 is a sectional view along the line 4-4 of figure 10.
  • Figure 5 shows in section the positions of the button and sector in the phase of figure 4.
  • Figure 6 is a sectional view similar to that of Figure 4 but the knob having been turned in the direction of the arrow f.
  • Figure 7 shows in section the positions of the button and sector in the phase of figure 6.
  • Figure 8 is a sectional view showing the sector in its position preceding the final phase for the command to open the lock.
  • Figure 9 shows the position of the button and the sector in the phase of figure 8.
  • Figure 10 shows in plan the sector.
  • Figure 11 shows in section the lock in the open position.
  • Figure 12 is a plan view of the sector in an alternative embodiment.
  • the lock shown in Figures 1 to 11 includes a housing 1 with a headrest 2 pierced with a opening 3 in which a latch bolt is movable 4 secured to a plate 5 sliding in a guide 6 and terminated by an elbow 7.
  • the plate 5 is pierced a light 10 in which is housed a spring 11 compression, one end of which cooperates with a nipple 12 of light 10 and the other end with the guide 6.
  • a rocker 15 having three fingers 16, 17 and 18, the finger 16 being cooperating with the elbow 7, the finger 17 receiving one end of a compression spring the other end of which is fixed to a lug 19, a stop 20 being provided in the housing to limit the pivoting of the rocker 15.
  • the finger 18 is intended to cooperate with a pusher 21.
  • the plunger 21 is slidably mounted in guides 22 and 23 against the action of a return spring 24 inserted between the guide 22 and a stop 25 provided on said pusher whose end, opposite to that cooperating with the finger 18, is terminated by a heel 27.
  • a button 30 is integral with a sector 31, which can pivot against the action of a spring 32 on a axis 33.
  • the sector in the normal rest position, door against the stop 34 provided in the housing 1.
  • a compression spring 36 which is arranged in a housing 37 of sector 31 and which, by one end, cooperates with a bearing 38 of the sector and, by the other end, carries against a head 39 of axis 33.
  • sector 31 tends to be applied against a wall of the housing 1 and can, with a pull on button 30 against said action spring 36, be approached from the wall 1b of said housing.
  • Sector 31 has a notch which is delimited by the cheeks 31a and 31b of said sector and in which cams 41, 42, 43, 44 are formed and a central groove 45 connected to the cam 41 by a bent part 46.
  • the cam 44 is terminated by a stop 48 and, in the vicinity thereof, there is provided a flange 50 of the side of groove 45.
  • Cam 41 (see Figures 2 and 10) has a portion which slopes gently from the cheek 31a towards the cheek 31b.
  • the cam 42 is in the shape of an arc of a circle having for center axis 33.
  • the cam 43 extends in a gentle slope from the cheek 31b towards cheek 31a, while cam 44 describes an increasing arc from the cam 43 towards the stop 48.
  • the lock being closed, it occupies the position Figures 1 and 2; the sector bearing on the stop 34. If we want to open, we pull on the button 30 against the action of the spring 36 in order to bring the sector 31 against the wall 1b, the heel 27 climbing the cam 41, then rotate the button in the direction of arrow f (see Figures 4 and 6) to bring the heel 27 to cam 43. Then push button 30 so the heel 27 climbs the cam 43 and we rotate the button 30 in the direction of the arrow g (see figures 8 and 9). Thus, the pusher 21 is moved so that, with the finger 18 being pushed, the finger 16 controls the opening bolt 4 (see Figure 11).
  • FIG. 12 a variant has been represented. in which, when the lock has been open and when the button is released, the lock returns in its initial position automatically.
  • the sector at the end of its cam 44a, has a spring 52 and the cam 44a is inclined in the direction of the groove 45a. So when the lock was opened, the heel 27 cooperating with the spring 52, the latter tends to repel said heel which, due to the inclination from cam 44a, falls into groove 45a, the spring 32 returning the sector to its initial position.
  • the position of the cams could, for example, be different.
  • This link can be selectively inserted between these two elements so that in some cases the lock works without the need to perform the corresponding maneuvers to the selected combination.
