Abstract

The device (1) has a support (4) including a stop portion radially carried with respect to an axis. A mobile transmission assembly (7) moves in translation along a direction parallel to a reference plane. A stop system is reversibly deformed between two configurations. The system cooperates with the stop portion to define an angular stop position for the support in one configuration and the portion slides at a contact for increased forces exerted on the support till another configuration in which the stop portion escapes from the system that elastically returns to the former configuration.

Description

The invention relates to an actuator for a door, in particular

  suitable for doors equipped with an anti-panic helmsman. In practice, the anti-panic helper of such a door is on the inside of the door to allow rapid evacuation of a room, and the operating member (or half-assembly) has the function of controlling the access to the premises from outside the door. Such a half-assembly is generally provided with a crutch and a control cylinder, the cylinder action to allow the opening of the door by action on the stand, or on the contrary to prohibit it . The opening of the door is done in practice by action on a follower driving the square of the lock.

  Standstand devices are known: when access from outside is condemned, the stand is locked in the waiting position, generally horizontal. Also known devices with disengaged jack: when access from outside is condemned, a disengagement mechanism decouples the rotation of the crutch of the rotation of the follower. An abutment limits the movement of the stand, and a torsion spring recalls it to its standby position which is generally horizontal. These two solutions have in common the disadvantage of allowing the door can be vandalized by a sustained support on the stand, that it is locked in horizontal waiting position or blocked at the end of stroke against a stop. The device is damaged either because the stand creases or breaks, or because the inside of the operating member is deformed or breaks. The object of the invention is to remedy this problem, and to provide a half-assembly type operating member which is not damaged by too much effort on the stand. Preferably the solution according to the invention must have good robustness for a minimum space requirement.

For this purpose, the invention proposes an actuator adapted to be mounted on a leaf having a lock by a face defining a reference plane perpendicular to an axial direction, said actuating member comprising a body containing at least part of A stand support rotating about a first axis parallel to said axial direction and fixed relative to said body, said stand support having a stop portion radially offset relative to said first axis, a follower rotating around a second axis parallel to said axial direction and fixed relative to said body, adapted to act on a square of the lock, a control cylinder accessible from outside the body, having at least two positions and adapted to be tilted from one to the other in response to the action of a user, 15 - a movable assembly of mobile transmission in translation in a direction of translati parallel to the reference plane, switchable between at least one engaged configuration and a disengaged configuration under the action of said control cylinder and such that the rotation of the stand support causes the translation of said mobile transmission unit, and that in the configuration engaged the translation of said movable transmission assembly causes the rotation of the follower, and a stop system carried by said body, deformable reversibly between at least two conformations and adapted in a first conformation to cooperate with said abutment portion to define a position. angular abutment for the stand support, said stop system deforming for increasing efforts exerted on the stand support to a second conformation for which the abutment portion escapes said abutment system by sliding in contact therewith , said stop system being elastically biased towards its first end conformation.

This device has the advantage of not being able to be damaged by an excessive rotation action on the stand, that is to say to be protected against vandalism. Indeed, the movable transmission unit 2909701 3 makes it possible to disengage the rotation of the follower from the rotation of the stand support, and when a too high rotational force is applied, the stop system reversibly deforms and allows said support to rotate. crutch, which prevents the breakage or damage of the device. Furthermore, the set 5 movable in translation being movable in a direction parallel to the reference plane, the space in the axial direction is limited. Preferably, the mobile transmission unit comprises a first transmission element cooperating with the stand support, and a second transmission element cooperating in the engaged configuration with the follower, said second transmission element undergoing, between the disengaged configuration and the configuration engaged, with respect to said first transmission element, a shift transverse to said translation direction. Preferably, the mobile transmission unit is composed of a plate mounted in translation relative to the body and a clutch part rotatably mounted relative to said plate, the first transmission element being carried by said plate, and the second transmission element being carried by said clutch part. These features offer the advantage of simplicity and strength for a limited space requirement. Furthermore, the term wafer should not be understood in a limiting manner and includes various forms of room. Preferably, said stand support has an action section, possibly offset along said first axis relative to the abutment portion, which comprises an action portion radially offset relative to said first axis, the first transmission element of said assembly. mobile transmission being a bearing surface in contact with which said action section slides, and such that from a rest position of the stand support, the rotation of the action portion causes the translation of the surface pressing support, and such that a biasing member attached to said body holds the movable transmission assembly in contact with said stand support and recalls said movable transmission assembly and said stand support each to a return position.

2909701 4 This offers the advantage that the mechanism is simple and strong, for a minimum footprint. Moreover, the rotation of the stand can be unlimited, thanks to the return element. Preferably, said biasing element is a compression spring, which offers the advantage of simplicity and robustness. Preferably, the assembly consisting of the action section, the mobile transmission unit and the follower has, for a position of the stand support and a configuration of the mobile transmission unit, a symmetry with respect to a plane including said first axis. This allows the actuator to be mounted on a door indifferently left or right. Preferably, the follower has a support zone offset relative to the second axis and the second transmission element of the mobile transmission unit comprises an action surface acting on the support zone, preferably by pushing. This offers the advantage that the mechanism is simple and solid. Preferably, the follower further comprises a recess adjacent to the bearing zone and the second transmission element further comprises a lug adapted to penetrate into said recess. This allows a greater rotation of the follower. Preferably, the control cylinder acts on the configuration of the mobile transmission assembly by means of a locking member movable in translation relative to the body and movable in rotation and in translation relative to the mobile transmission unit . This offers the advantage that the mechanism is simple and solid. Preferably the locking member is movable in rotation and in translation relative to the second transmission element or the clutch part of the mobile transmission unit. Preferably, the locking piece is mounted relative to the mobile transmission unit via a lug inserted into a slot. Preferably, the locking piece is also rotatable relative to the body, for example around a perpendicular axis 2909701 5 to the reference plane. This allows the mechanism, in the engaged position, not to be damaged in case of resistance to the rotation of the follower. Preferably, the locking piece is mounted relative to the body via a lug inserted into a slot.

Preferably, the locking piece has a symmetry with respect to a plane perpendicular to the reference plane, which allows it to be used in left-hand mounting or right-hand mounting. Preferably, the stop system comprises an elastic blade. This has the advantage that such an elastic strip is simple to implement and easy to replace in case of wear. Preferably, said elastic strip is made of spring steel. Preferably, said stand support has an abutment section of generally elongate shape, said abutment portion being an eccentric portion of said abutment section. In other words, the circumference envelope of the abutment portion section comprises at least one area at a first distance from the first axis and a second area at a second distance from the first axis, the second distance being greater than at the first distance, the envelope of the circumference of the section of the stop portion being able to slide in contact with the elastic strip. This offers the advantage that the mechanism is simple and strong for minimum bulk. Preferably, the second distance is substantially greater than the first distance. Preferably, the stop system comprises two elastic strips on either side of the stand support. This provides greater robustness to the mechanism. Preferably, the position of the follower when the stand support is in abutment is such that the square of the lock is in a position adapted to the opening of the door. Preferably, the assembly consisting of the abutment section and the abutment system has, for a position of said crutch support, a symmetry with respect to a plane including said first axis.

Preferably, the assembly consisting of the action portion and the mobile transmission assembly has, for a stand position and a configuration of the mobile transmission unit, a symmetry with respect to a plane including said first axis.

Preferably, the axes of the stand support and the follower are merged. Preferably, the operating member is adapted to or, preferably, intended to be implemented on a door provided with an anti-panic bar.

The description of the invention will now be continued by the description of an exemplary embodiment, given below by way of nonlimiting illustration, with reference to the appended drawings in which: FIG. 1 is a general view of the various parts of an actuator according to the invention.

Figures 2, 3 and 4 are views from three different angles of the stand support of the operating member. Figure 5 is a view of the follower of the actuator. Figure 6 is a view of the mobile transmission assembly of the actuator in an engaged configuration.

Figure 7 shows a view of the mechanism of the actuator in the disengaged configuration of the movable transmission assembly. FIG. 8 represents a detailed view of the mechanism of the operating member in the disengaged configuration of the mobile transmission assembly, the stand of the operating member being tilted by an external operator.

FIG. 9 represents a detailed view of the mechanism of the operating member in the engaged configuration of the mobile transmission unit. Figure 10 shows a detailed view of the mechanism of the operating member in the engaged configuration of the movable transmission assembly, the stand of the operating member being tilted by an external operator. FIGS. 11, 12, 13 and 14 show a sectional view of the abutment portion of the stand support and the abutment system of the actuating member in four dispositions: initial disposition, abutment arrangement, forcing arrangement, provision after forcing, corresponding to four positions of the stand of the operating member. With reference to FIG. 1, a half-assembly actuating member 1 intended to be fixed to a door by a face 2 parallel to a reference plane comprises an elongate body 3, a stand support 4 rotating about a first axis perpendicular to the reference plane, a follower 5 rotating about a second axis here coinciding with the first axis, a control cylinder 6, a movable transmission member 7 mounted in translation relative to the body 3, resilient strips 8 forming a stop system, a spring 9 and a locking piece 10. The rest position of the stand is perpendicular to the elongation direction of the body 3 and parallel to the reference plane. Figures 2, 3 and 4 show in more detail the stand support 4, which has a plurality of axially offset sections, among which an action section 41 and an abutment section 42. The two sections 41 and 42 are radially elongate, so that their circumference is not a center circle carried by the axis of the stand support, but differs in the presence of peripheral bulges.

The action section 41 has a general bow-tie shape including a central cylindrical portion connected by two narrowed portions to two action portions 410 having the shape of peripheral protuberances.

The stop section 42 has a generally oval shape and its eccentric portions form two abutment portions 420. Finally, the stand support 4 comprises a fixing section of the stand 43 of conventional type, known to those skilled in the art. Furthermore, the stand support 4 has a plane of symmetry which includes its axis. FIG. 5 shows the follower 5 of the operating member, which comprises an axis of rotation, two bearing zones 51 offset relative to this axis, a recess 52 adjacent to each of the bearing zones 51, as well as a socket 53 adapted to act on the square of the lock (visible in Figure 7, not shown in the other figures), in a manner known to those skilled in the art. The bearing areas 51 are curved and convex so that a force can be exerted from different angles. They are symmetrical to one another with respect to a plane including the axis of rotation of the follower 5. The recess 52 is symmetrical about itself with respect to this same plane.

Referring to Figure 6, the movable assembly in translation 7 comprises a plate 71 and a disengaging member 72 movable in rotation relative to the plate 71 via a pivot connection conventionally achievable by the skilled person. The wafer 71 is flat, of generally rectangular shape and has a plane of symmetry perpendicular to its plane and parallel to its longer side. The pivot connection connecting the plate 71 and the clutch part 72 is positioned on the plate 71 near one of the short sides of the rectangle. The wafer has a central opening in a direction perpendicular to the plane of the wafer, the contour of this opening being here closed. The edge 25 of the central opening of the wafer 71 on the pivot connection side comprises successively a first flat portion, a circular portion and a second flat portion, forming a bearing surface 73 directed away from the pivot connection. . The disengagement piece 72 is flat, of generally elongate shape and has a plane of symmetry perpendicular to its plane and parallel to its longitudinal direction. The pivot connection connecting the plate 71 and the clutch part 72 is positioned on the clutch part 72 at an eccentric location in the longitudinal direction. The disengagement piece 72 has a central opening in a direction perpendicular to its plane, the contour of this opening being closed here. Two lugs 75 forming teeth protrude inwardly from the central opening of the disengaging part 72. The edge of the central opening has, at each lug 75, an action surface 74 directed into the direction of the pivot connection, a portion of the action surface 74 being concave. The lugs 75 and the action surfaces 74 are offset relative to the pivot connection. With reference to FIG. 7, the stand of the operating member 10 has a conventional rest or return position, typically horizontal when the operating member is placed on a door, and perpendicular to the large dimension of the body 3. As it appears in FIGS. 7, 8, 9 and 10, the plate 71 is, in operation, movable relative to the body 3 in translation in a direction of translation 15 parallel to the reference plane and perpendicular to the rest position of the crutch . The clutch part 72 is rotatable relative to the plate 71 about an axis perpendicular to the reference plane. The large size of the wafer 71 is positioned perpendicular to the stand position of the stand and the pivot connection connecting the wafer 71 to the clutch piece 72 is positioned upwardly. Referring to Figure 7, the locking member 10 is, relative to the body 3, movable in translation parallel to the reference plane and parallel to the direction of the stand in its rest position. The locking piece 10 is, relative to the body 3, also rotatable about an axis perpendicular to the reference plane. This connection is achieved by a cylindrical lug carried by the body 3 or integral thereof and sliding in an oblong slot made through the locking member 10, perpendicular to the reference plane. This slot is elongated parallel to the direction of the stand in its rest position and blind at both ends. The locking piece 10 is also, relative to the clutch part 72, movable in translation parallel to the reference plane and 2909701 10 rotatable about an axis perpendicular to the reference plane. This connection is made by a cylindrical lug carried by the clutch part 72 and sliding in an oblong slot made through the locking part 10 perpendicularly to the reference plane. This slot is elongated perpendicular to the direction of the stand in its rest position and blind at both ends. The rotation of the control cylinder 6 controls in a conventional manner, known to those skilled in the art, the displacement of the locking piece 10, which causes the clutch part 72 to rotate relative to the plate 71, the bringing the disengaged configuration (Figures 7 and 8) to the engaged configuration (Figures 9 and 10). This rotation causes a shift transverse to the direction of translation of the mobile translation assembly 7 of a lug 75 and the corresponding action surface 74. The spring 9 bearing against the body 3 holds the plate 71 15 against the stand support 4, by an action against the upper outer edge of the wafer 71, which is closest to the pivot connection. An action portion 410 in contact with a flat portion of the support surface 73. In the disengaged configuration (FIGS. 7 and 8) or engagement (FIGS. 9 and 10), an action on the stand causes rotation of the stand support. 4, 20, an action portion 410 pushes the bearing surface 73 upwards, which causes the translation of the mobile transmission assembly 7 in its translation direction, against the spring 9. The circumference of the action section 41 slides on the bearing surface 73. These movements are reversible. From FIG. 8, it can be seen that the circumference of the circumference of the action section (41) comprises an area at a first distance from the axis of the stand support (4) and a second area at a second distance. of this axis, the second distance being greater than the first distance. The envelope of the circumference of the action section (41) slides in contact with the bearing surface 73.

In the disengaged configuration (FIGS. 7 and 8), the lugs 75 do not interact with the follower 5, and the action surfaces 74 are then not in contact with the bearing zones 51. No action on the square of the lock does not result from the action on the stand. In the engaged configuration (FIGS. 9 and 10), a lug 75 is positioned opposite a bearing zone 51 of the follower 5. An action on the stand causes, as previously, the rotation of the stand support 4, which causes, by via an action portion 410 in contact with a flat portion of the bearing surface 73 the translation of the mobile transmission unit 7 in its translation direction. An action surface 74 comes into contact with a bearing zone 51 and the action surface 74 pushes the bearing zone 51. The corresponding pin 75 engages in the recess 52, the thrust of the support zone 74 on the action surface 51 causes the rotation of the follower about its axis, the action surface 74 rolls on the bearing zone 51 and the insertion of the pin 75 in the recess 52 allows to extend the action of the action surface 74 on the bearing zone 51. The translation of the movable assembly 15 transmission 7 causes by this mechanism the rotation of the follower 5 about its axis. These movements are reversible. When the action on the stand comes to an end, the spring 9 recalls the mobile transmission element 7 and the stand support 4 towards their rest or return position (see FIGS. 7 and 9).

Figures 11, 12, 13 and 14 show a sectional view of the abutment section 42 and abutment portions 420 of the strut support 4 and the abutment system of the actuator in four arrangements. First, FIG. 11 shows the position of the mechanism in the initial position where the stand is in the normally horizontal position of rest (see FIGS. 7 and 9). The abutment section 42 is not in contact with the elastic slats 8 which are carried by the body 3. FIG. 12 shows the position of the mechanism after a rotation of the stand 45 or about 45 relative to the initial position (see Figures 8 and 10). The abutment section 42 is via its abutment portions 420 in contact with the elastic lamellae 8, so that the resistance caused by this contact can enable the operator operating the stand to feel that the mechanism is in abutment.

Figure 13 shows the position of the mechanism after further rotation of the stand. The elastic strips 8 have deformed towards a deformation conformation to leave space for the abutment portions 420, which slide in contact with the elastic strips 8, because of the force applied to the stand support 4 and its accumulation. . Importantly, the deformation of the elastic strips 8 is without exceeding the elastic limit of the material chosen, here spring steel. The choice of this material and the geometric characteristics of the slats 8 is easily achieved by those skilled in the art.

Figure 14 shows the position of the mechanism after further rotation of the stand. The abutment portions 420 have moved away from the slats 8 which have returned to their initial conformation, due to the force applied to the support crutch 4 and its accumulation. The stand is in the inverted position (not shown) relative to its original position.

An additional half-turn, in one direction or the other, is necessary to return the operating member to its initial position shown in FIG. 11. It can be seen from FIGS. 11 to 14 that the stop system acts in a first conformation so as to prevent a complete rotation of said stand support 4, and is adapted in a deformed conformation to allow rotation of the stand support 4 so that in the disengaged configuration of the mobile translation assembly a complete rotation of said support crutch 4 is possible. The deformation of the abutment system from its first conformation to its deformed conformation occurs for a rotational force applied to the abnormally sustained or raised stand support, typical of a so-called vandalism situation. Furthermore, with reference to FIGS. 6 and 8, the bearing surface 73 of the mobile transmission unit 7 comprises a flat part and a circular part so that the rotation of the stand support 4 causes the translation of the mobile transmission unit 7 when an action portion 410 is in contact with a flat portion of the bearing surface 73, and that, conversely, the rotation of the support leg 4 does not cause the translation of 2909701 13 the movable transmission assembly 7 when the action portion 410 is in contact with the circular portion, which configuration corresponds to the deformation conformations of the stop system (Figure 13). Finally, the position of the follower when the stand support is in abutment 5 (Figure 12) is such that the square of the lock is in a position adapted to the opening of the door. The invention can not be limited to the embodiments described above. It is possible to envisage, within the scope of the present invention, a variant where the control cylinder is replaced by a control element not in rotation but in translation. Optionally, the disengaging member may be mounted in translation relative to the wafer in a direction transverse to the direction of translation thereof relative to the body.

It can also be envisaged, for example, that the conversion of the rotational movement of the stand support into a translation movement of the movable transmission member is done by a rack system. It is also conceivable that the conversion of the translational movement of the movable transmission member into a rotational movement of the follower is also done by a rack system. The abutment system may optionally, while also remaining within the scope of the present invention, comprise instead flexible slats for example a system of non-flexible slats retained by compression springs.
