Definitions

  • the present invention relates to a lock for overhead doors, doors in sections or curtains, of the type comprising a box, at minus a control member for a lock, a rotary handle, a device of engagement between said handle and said control member for a lock, a lock block and possibly a control member internal, said interlocking device being capable of taking two configurations, including an active configuration, in which it establishes a connection between the handle and said control member, so that the handle is able to activate said lock, and an inactive configuration, in which it does not establish this connection between the handle and said control member, so that the handle is not able to actuate said lock and it remains mad, said interlocking device remaining normally in its inactive configuration and can be moved in its configuration activates by actuating said lock block or, if it exists, said internal control.
  • a type of lock as mentioned above may be preferred, in particular general, to a type of lock in which the handle is normally locked and can be turned only after the consent of the lock block, because in this last type of lock the handle can be forced by applying a high force, and in order to sufficiently prevent this possibility the parts of the lock must be made in a very massive form and therefore heavy and expensive.
  • most locks for overhead doors, sectional doors or curtains belong to the latter type, because, in consideration of the structure of the locks intended for these applications, it is not easy, as in other types of locks, to realize an interlocking device capable of leaving the handle mad when the lock is closed.
  • an object of the present invention is to provide a lock for overhead doors, sectional doors or curtains, which have usually one or two closing points, including an interlocking device which should be likely to leave the handle crazy at least in its closed position, making it become active only when the lock block or an internal control member has been operated, and which must be solid, secure, of a substantially simple structure and of easy construction and assembly and therefore relatively economical.
  • Another object of the invention is to produce such a lock in which all moving parts of the lock are subject only to displacements in perpendicular planes of the axis of rotation of the handle, which allows a substantial simplification of the structure and assembly operations of the lock. Another goal is to achieve such lock whose assembly can be carried out mechanically by robots. Another goal is to make such a lock which can be made with reduced thickness. It is also a goal to achieve such a lock in which no part is subject to high stresses, so that there is no need to resort to massive construction of any part.
  • a lock of the type recalled in that the rotary handle is integral with a transmission member provided with lugs, that said control member for a lock is provided with a pawl capable to take two positions, including an active position in which it can engage a lug of said transmission member to be actuated therefrom, and an inactive position in which it is outside the trajectory of lugs of said transmission member so that it cannot be actuated therefrom, that first elastic means normally stress said pawl towards its inactive position, and that a body of consent, mobile under the action of the lock block and possibly of said internal control member, is arranged to neutralize the action of said first elastic means and allow or control the movement of said pawl in its active position.
  • said consent body is limited to neutralizing the action of said first elastic means for allowing said pawl to move towards its position active, and this movement is carried out by second elastic means which act on the pawl with a force more reduced by the force of said first elastic means and which therefore do not have the possibility of acting until that said first elastic means are active.
  • said consent body acts positively on the pawl against the action of said first elastic means, by controlling or enabling the movement of the pawl towards its active position.
  • Said pawl can be shaped in order to cooperate in both sense, in its condition of activity, with the lugs of the transmission organ, for positively controlling said control member for a lock either in opening than in closing, or else said pawl can be shaped as to cooperate only in one direction, in its position of activity, with the lugs of the transmission member, for positively controlling said member for a lock when opening but not closing, the closure being in such case ensured by elastic third parties, acting on the control member for the lock.
  • a fourth elastic means is arranged to act between a control member and the box, so as to stabilize the two positions of the control unit.
  • the lock according to the invention can be produced with a control for a lock only, provided with said pawl, or it can be carried out with two control elements for two locks, one of these control members being provided with said pawl, and a tilting lever being pivoted in said box and being engaged with the two control members to ensure corresponding displacements in opposite directions.
  • an elastic member arranged to act against the lugs of said transmission member in order to stabilize by triggers elastic of the prefixed positions of the handle.
  • An elastic member can also be provided to stabilize the position of said consent body.
  • Two or more of the functions of elastic organs mentioned can be entrusted to a single elastic organ.
  • the lock shown in Figures 1 to 4 is of a type (called “turn”) in which either the opening or the closing of the lock must be ordered by rotation of the handle; on the contrary, the lock shown in Figures 5 to 7 is of a type (called “spring”) in which only the opening of the lock must be controlled by rotating the the handle, while closing is carried out automatically by a spring.
  • a lock according to the first embodiment of the invention comprises a box 1, at least one control unit 2 for a lock (but in this case also a second control member 3 for another lock), a rotary handle, which is shown only the hub 4 having a prismatic graft for coupling the external part (not shown) of the handle, a lock block 5 (in this case a so-called European cylinder) with its bit 6, and an internal member 7 for controlling the opening.
  • a lock block 5 in this case a so-called European cylinder
  • a rotary member 8 is integral with the rotary handle 4 provided with lugs 9, and the control member 2 is provided with a pivoted pawl 10 in 11 to this body.
  • the pawl 10 can take two positions, including an active position ( Figures 3 and 4), in which he can engage a lug 9 of the transmission member 8 to be actuated, and a position inactive ( Figure 1), in which it is outside the trajectory lugs 9 of the transmission member 8, so that it cannot be operated.
  • the pawl 10 is under the action of a spring 12, of relatively strong reduced, which tends to rotate it in the vicinity of the organ of transmission 8, that is to say, to bring it to its active position.
  • a consent device 14-15 in the form of a rocking lever, with an arm 14 which interferes with the trajectory of the bit 6 of the lock block 5, and an arm 15 which, under the action of a spring 16, pushes the pawl 10 towards its inactive position, making it penetrate for this purpose into a notch 2 ′ of the control member 2.
  • Au arm 15 of the consent member is connected to the internal control member 7 of the opening.
  • the springs 12 and 16 are proportioned in such a way that the action of the spring 16 must prevail over the action of the spring 12, so that in the configuration according to Figure 1 the pawl 10 is retained in its inactive position. In this condition, because the transmission member cannot engage the pawl 10, the handle 4 is crazy.
  • the device described operates as follows. We said that in the condition closing according to Figure 1 the handle 4 is crazy and the body control 2 is blocked, so that the lock cannot be opened. But if the lock block 5 is actuated by its corresponding key, the bit 6 during its rotation pushes the arm 14 of the consent member and turns it, moving the arm 15 away from the pawl 10, against the action of the spring 16. The spring 12 is then free to move the pawl 10 by making it interfere with the trajectory of the lugs 9 of the transmission member 8.
  • the transmission member 8, the pawl 10 and the consent organ 14-15 constitute an interlocking device between the handle 4 and the control member 2 for a lock
  • this interlocking device is likely to take two configurations, including an active configuration, in which it establishes a connection between the handle and the controller, so that the handle is able to operate the lock, and an inactive configuration, in which it does not establish this connection between the handle and the control member, so that the handle is unable to operate said lock and remains mad, said device normally in its inactive configuration and can be moved in its active configuration by actuating the block lock or, if there is one, the internal control member for the opening.
  • the handle remains crazy also in the open position of the lock, when desired.
  • the control member 2 is provided, in plus the notch 2 ′ already described, also a second notch 2 "(FIG. 4), disposed in front of the arm 15 of the consent member when the lock is found in the open position.
  • the spring 16 is able to overcome the force of the spring 12 and push the pawl 10, moving it to its inactive position and thus making go crazy the handle.
  • a pin spring 18 (shown only in Figures 1 and 2) stabilizes the open and closed positions of the organ 2 to prevent possible accidental movements.
  • this second member control 3 is slaved to the first control member 2 by means of a rocking lever 19 mounted rotating in the box 1 (for example coaxial with the handle 4) and the ends of which are engaged with the two members of command 2 and 3, to force them to make contemporary trips, equal and opposite.
  • a lock conforming to the second embodiment of the invention comprises a box 21, at least one control member 22 for a lock (but in this case also a second control member 23 for another lock), a rotary handle, of which only the hub 24 is shown having a graft prismatic for the coupling of the external part (not shown) of the handle, a lock block 25 (in this case a so-called European cylinder) with its bit 26, as well as, optionally, an internal control member of the opening (not shown).
  • the control member 22 is requested vice versa its closed position by a spring 27.
  • the rotary handle 24 is integral with a transmission member 28 provided with pins 29, and the control member 22 is provided with a pawl 30 pivoted at 31, in a sliding manner, to this member by means of a slot 33.
  • the ratchet 30 can take two positions, one of which is active ( Figures 6 and 7), in which it can engage a lug 29 of the transmission 28 to be actuated, and an inactive position (FIG. 5), in which it is outside the trajectory of the pins 29 of the member transmission 28, so that it can not be actuated.
  • Ratchet 30 is under the action of a spring 32, which tends to make it slide and rotate to move it away from the transmission member 28, that is to say, to bring it towards its inactive position. In the configuration according to FIG. 5, the pawl 30 is therefore retained by the spring 32 in its inactive position.
  • a consent device 34-35 in the form of a tilting lever, with an arm 34 which interferes with the trajectory of the bit 26 of the block lock 25 and also with the path of part of the pawl 30, and an arm 35 which cooperates with a profiled spring 36, which stabilizes two operating positions from the consent body 34-35.
  • the consent body 34-35 To the consent body 34-35 is connected the internal control member of the opening, if there is one.
  • a second arm 37 of the spring 36 is pressed against the pins 29 of the member transmission 28 and it retains the handle 24 in a stable position, all without prevent a controlled rotation.
  • the transmission member 28, the pawl 30 and the consent member 34-35 constitute an engagement device between the handle 24 and the control member 22 for a lock
  • this interlocking device is capable of taking two configurations, including an active configuration, in which it establishes a link between the handle and the control member, so that the handle is able to activate the lock, and an inactive configuration, in which it does not establish not this connection between the handle and the control member, so that the handle is unable to operate said lock and remains proficient, said latching device normally in its inactive configuration and can be moved in its active configuration by actuating the lock block or, if there is one, the internal control member for the opening.
  • this second member control 33 is slaved to the first control member 32 by means of a rocking lever 39 mounted rotating in the box 21 (for example pivoted in 20) and the ends of which are engaged with the two control members 32 and 33, to force them to make contemporary trips, equal and opposite.
  • the invention is capable of application in many types of locks for overhead doors, sectional doors or curtains, whether tower type or spring type, and are they with only one lock or two locks. It also stands out clearly that the structure of the lock is relatively simple, given of its performance, and that its manufacture and assembly pose no particular problem, so it is substantially economical.
  • the invention is not limited to the modes of realization which has been described and represented as examples. Several modifications are within the reach of the skilled person.
  • the transmission organ 8 or 28 has been shown with four lugs, but the number of its pins can be different; in the first embodiment the main lock was assumed to be the one 2 at the top, and in the second mode 22 which is at the bottom, but these provisions can be reversed; the lock block 5 or 25 was assumed to be of the so-called European cylinder type, but also other kinds of mechanisms can be used, whether they are with a rotary bit or with a lock movable in translation.
