Definitions

  • the present invention relates to a device for locking and unlocking any organ, such as for example a bar carrying bolts capable of cooperating with strikes to lock a door, for example.
  • the keeper is equipped with a small movable flap which retracts under the effect of the current and consequently releases the bolt.
  • This system has drawbacks. First of all, it consumes a certain amount of electrical energy insofar as the strike flap must be kept electrically excited for a certain time necessary for unlocking. In addition, the locking of the U-bolt in the strike is not positive, since this U-bolt is biased by a simple spring and can be easily hooked and extracted from the electric strike.
  • a device for locking and unlocking a door comprising a bolt slidably mounted in a body integral with the door and actuated by a first electromagnet allowing to this bolt to cooperate or not with a keeper integral with the door frame, while a second electromagnet integral with the door can act on the bolt in order to block it in the body when it is in the position of introduction into the keeper.
  • This device unlike the system described above, provides a positive blocking of the bolt in the position inserted in the keeper and requires, for its operation, only a very low consumption of electric current.
  • this device due to the one-piece structure of the bolt, can deteriorate in the event of the bolt jamming in the strike or of misalignment of the bolt with the strike.
  • the present invention aims to provide a device which overcomes in particular the drawbacks resulting from possible jamming and possible misalignment of the bolt vis-à-vis the member to be locked.
  • the subject of the invention is a device for locking and unlocking any organ, and of the type comprising at least one bolt mounted to slide in a body and actuated by a first electromagnet allowing this bolt to cooperate or not with a notch or the like forming a keeper formed in said member, as well as a second electromagnet acting on the bolt so as in particular to block it in the body when it is in the position of introduction into the keeper, characterized in that that the bolt is formed on the one hand of a rear part cooperating with the core of the second electromagnet, and on the other hand of a front part cooperating with the keeper and mounted relatively mobile relative to the rear part.
  • the rear part of the bolt has on its periphery two recesses or spaced annular grooves cooperating with the core of the second electromagnet.
  • the front piece of the bolt is constituted by a hollow element in which slides a rod carrying at its free end a stop for a first spring surrounding the rod and constantly urging the hollow element in position bearing against the stop, this rod being integral with the rear part of the bolt which it crosses and constituting the core of the first electromagnet.
  • a second spring surrounds the above-mentioned rod and bears between the rear part of the bolt and the bottom of the body in which the bolt slides.
  • a third spring is also provided for constantly biasing the core of the second electromagnet in the direction of the rear part of the bolt.
  • the first electromagnet is fixed externally to the body and in the axis of this body, while the second electromagnet is fixed externally to the body so that its core is orthogonal to the axis of the body and passes through a bore formed in said body and opening onto the rear part of the bolt.
  • the two electromagnets are electrically connected so as to allow their selective excitation or de-excitation according to the sequence of operations to be carried out, in particular to release, activate and block the bolt in the body.
  • FIGS. 1 to 4 illustrate the successive steps allowing the device to pass from the locked position to the unlocked position
  • FIGS. 5 to 7 illustrate the passage from the unlocked position to the locked position.
  • Figures 8 and 9 illustrate the operation of the device in case of jamming of the bolt in the keeper
  • Figures 10 and 11 illustrate the operation of the device in case of misalignment of the bolt with the keeper.
  • FIG. 1 to describe the structure of the device according to the present invention and shown in an enlarged view.
  • This device essentially comprises a bolt 1 mounted to slide in a body 2 and which can cooperate with a notch 3 forming a keeper formed in any member, such as for example a bar 4 carrying bolts 5 allowing, by action bar 4, locking or unlocking a safe door for example.
  • the body 2 has at one of its ends an opening 6 allowing the passage of the bolt 1, and is closed at the other of its ends by a removable bottom 7.
  • the bolt 1 consists of a rear piece 8 in the form of a socket and of a front piece 9 capable of cooperating with the keeper 3 and mounted relatively mobile relative to the rear piece 8.
  • the rear piece 8 and the front piece 9 bolt 1 are slidably mounted in the body 2.
  • the front part 9 of the bolt 1 is constituted by a hollow element 10 in which slides a rod 11 provided at its free end with a stop 12 capable of sliding in the bore 10a of the hollow element 10.
  • a first spring R i surrounding the rod 11 and housed inside the bore 10a abuts on the one hand on the stop 12 and on the other hand on the rear part 10b of the element 10 and through which the rod 11 passes
  • the spring R 1 constantly urges the hollow element 10 to bear on the stop 12 of the rod 11.
  • the rear part 10b of the hollow element 10 normally bears on the part rear 8 of bolt 1.
  • the rod 11 is fixed to this rear part 8 which it crosses and constitutes the core of a first electromagnet 13 externally fixed to the body 2 by means of a lug or the like 14 and this along the axis XX 'of this body.
  • a second spring R 2 surrounds the rod 11 and bears on the one hand on the rear part or heel 8a of the part 8 and on the other hand on the bottom 7 of the body 2.
  • the rear part 8 of the bolt 1 has in a way the shape of a socket and has two external and spaced annular grooves 15 and 16. These two grooves 15 and 16 can cooperate with the core 17 of a second electromagnet 18 fixed on the side of the body 2 by means of a tab 19 for example.
  • a third spring R 3 mounted around the core 17 bears on the one hand on the body of the electromagnet 18 and on the other hand on a ring or the like 20 integral with the core 17 and sliding in a bore 21 formed through of the wall of the body 2 and opening onto the rear part 8 of the bolt 1.
  • the bore 21 and therefore the core 17 of the electromagnet 18 extend in a direction orthogonal to the axis XX 'of the body 2, this axis also being that of the bolt 1 constituted by the rear part 8 and the front part 9 which cooperates with the keeper 3.
  • grooves 15 and 16 of the rear part 8 could be formed by recesses of any shape capable of cooperating with the core 17 of the second electromagnet 18, without departing from the scope of the invention.
  • the body 1 of course includes an axial cavity 22 in which the bolt slides 1. There is shown at 23 a shoulder formed in the cavity 22 and which limits the stroke of the rear part 8 of the bolt 1 forwards under the effect compression of the second spring R 2 . Indeed, as can be seen in Figure 1, the heel 8a of the part 8 abuts on the shoulder 23 in question, which corresponds to a position introduced by the front part 9 of the bolt 1 in the notch 3 from bar 4.
  • the bar 4 is blocked by the front part or part 9 of the bolt 1.
  • the exit of the front part 9 of the keeper 3 is prohibited by the presence of the rear part 8 whose groove 16 receives the core 17 of the electromagnet 18. In this position, the system is at rest and the electromagnets 13 and 18 are not energized.
  • the electromagnet 13 While maintaining the excitation of the electromagnet 18, the electromagnet 13 is excited, which, as seen in FIG. 3, causes the rod 11 constituting the core of the electro-recoil magnet 13. Consequently, the crew constituted by the rear part 8 and the front part 9 both constituting the bolt 1 is moved until the heel 8a of the part 8 comes to abut against the bottom 7 of the body 2 In this position, visible in FIG. 3, the front part 9 of the bolt 1 has come out of the keeper 3, and the spring R 2 is compressed.
  • the electromagnets 13 and 18 are excited simultaneously, which allows the core 17 of the electromagnet 18 to come out of the groove 15 of the rear part 8, as seen in FIG. 5. It should be noted here that the spring R 2 is compressed, as well as the spring R 3 .
  • FIGS. 8 and 9 We will now refer to FIGS. 8 and 9 to briefly explain the operation of the device in the event of the front part 9 of the bolt 1 jamming in the notch 3 of the bar 4.
  • FIG. 8 This state is illustrated in FIG. 8 where we see the wall of the notch 3 of the bar 4 resting on the front part 9 of the bolt 1.
  • the locking cycle can be carried out as explained with reference to FIGS. 5 to 7, but here, as can be seen in FIG. 11, the element 10 of the bolt is not engaged in the notch 3 of the bar 4 and abuts on this bar while being compressed by the spring R 2 .
  • the core 17 of the electromagnet 18 is supported on the rear part 8 of the bolt 1 between the two grooves 15 and 16.
  • this element will enter the notch under the effect of the compression of the spring R 2 , and the blocking of the bolt 1 will be obtained by the penetration of the core 17 of the electro -like 18 in the groove 16 of the rear part 8 of the bolt 1.
  • a locking and unlocking device has therefore been produced according to the invention which consumes a minimum of electric current, which makes it possible to obtain a locking of the bolt in the locked and unlocked position, and which overcomes the drawbacks of jamming and failure to alignment of the bolt with respect to the member to be locked.
