DESCRIPTION

Device for closing a construction site consisting of assistance means for locking and unlocking the sheet

Technical sector

The present invention relates to a device for closing a construction gap, made by means of profiles, consisting of:

- a sleeper,

- a practicable sheet or swing leaf, associated to the sleeper by means of a pivotal connection,

- a locking and unlocking system of the sheet on the sleeper, comprising at least one strike means and at least one suitable latch means for cooperating with the strike means for locking the leaf on the sleeper, one of said being Locksmith means or latch means associated with the blade and the other with the sleeper,

- control means of the locking and unlocking system.

State of the art

The prior art teaches such closing devices. The locking and unlocking are carried out by means of a maneuvering handle that the operator must grasp and operate, for example, by rotation. The handles can be, on the one hand, arranged in a location that some people can only access with difficulty, in particular, people with reduced mobility and, on the other hand, demand an effort, which is often important, to operate by rotation of the handle the compression of the sealing gaskets simultaneously for blocking or overcoming the blocking / friction effort due to this compression during unlocking by reverse rotation of the handle.

The state of the art consists, in particular, of documents EP2206862A2 and AT509225A4.

Object of the invention

The present invention proposes to alleviate these inconveniences. More precisely, it proposes a device for closing a construction gap as defined in claim 1.

The solution, according to the invention, makes it possible to integrate a specific system, such as the one defined, of assistance for locking and unlocking, in the sheet and, more particularly, integrating system control means into a constituent profile thereof of blocking to return these means, at least in large part and more particularly the actuator, not apparent. Thus, in addition to the assistance for locking / unlocking, with the present invention it is intended to achieve an objective of improving the aesthetics of the sheet. A conventional locking device can be provided with the assistance system according to the invention by replacing the conventional maneuvering mechanism of the locking / unlocking system, while still using the existing lock and latch locking system, for example, a system of cremone rod with associated locking pins.

According to an advantageous feature, the rotating electric actuator has a motor shaft that supports the screw of said screw-nut type connection and is positioned so that its axis of rotation is parallel to the longitudinal direction of the profile in which it is arranged and the Locksmith means or latch means of the locking and unlocking system that is associated with the blade is fixed to the nut of said screw-nut type connection so that it moves in translation following said longitudinal direction of the profile with the nut.

According to an advantageous feature, the rotating electric actuator is linked to the profile on which it is arranged, by means of a connection plate on which the body of the rotating electric actuator is fixed and on which the screw-nut type connection is placed .

According to an advantageous feature, the control means of the locking and unlocking system also comprise an emergency mechanical system suitable for maneuvering by an operator by means of an emergency manual control in case of power failure of the rotating electric actuator.

According to an advantageous feature, said connection plate is linked to the profile of the sheet by means of a connection consisting of a degree of freedom in translation along the longitudinal axis of the profile and said connection plate is positioned so that it is mobile in translation through said emergency manual control means, at least between the following three positions:

- a first position or middle rest position, wherein said locking and unlocking system is located in locked or unlocked leaf position depending on whether the rotating electric actuator has been operated to its locked or unlocked leaf position respectively,

- a second position or active unlocking position, wherein said locking and unlocking system is located in the unlocked leaf position, the rotating electric actuator being locked in its locked leaf position, and

- a third position or active locking position, in which said locking and unlocking system is located in the locked leaf position, the rotating electric actuator being locked in its unlocked leaf position.

The arrangement of the electric actuator on an intermediate movable plate between the profile and the actuator, advantageously, makes it possible to remedy in a simple manner a failure of the actuator or of the power supply or other failures of the assistance control system for locking / unlocking, maneuvering the plate by means of a manual control, preferably concealed for aesthetic reasons, as will be explained later.

According to an advantageous feature, the control means of the electric actuator comprise a switch means suitable for being operated by an operator, whose visible upper surface is inscribed in a window made in an outer wall of a leaf profile.

The system according to the invention makes it possible to remove from the blade any operating handle of the locking and unlocking system and replace it with a more discreet switch means, for example, a sensor or touch switch, a wireless signal receiver for remote control operation. of the locking / unlocking system, an oral control receiver, etc ... The switch necessarily has the function of activating the unlocking of the leaf and, additionally, if necessary, as will be explained later, the blocking function of the sheet when this is not insured by another control body.

According to an advantageous feature, said emergency manual control means comprises a pinion-rack type device positioned so that the rack is fixed to said connecting plate, and that the pinion is placed inside the contour of said window made on an outer wall of a leaf profile and under the visible upper surface of said switch means, the pinion being provided with a suitable gripping means to cooperate with a tool with a view to the rotation of the pinion to maneuver the rack and the visible upper surface of said removable switch means for accessing said gripping means.

The window made in the profile allows double functionality: define the location of the switch means and thus its accessibility, while allowing very fluid aesthetics, for example, flush the upper surface of the switch means with the outer surface of the profile, and also allow access to the non-apparent manual lock / unlock which is advantageously concealed under the removable upper surface of the switch means.

According to an advantageous feature, said switch means is a touch switch.

The closing device according to the invention also comprises the immobilization system of the sheet with respect to the sleeper in a pre-locking position, the sheet being applied against the sleeper and not locked, positioned such that said striker means and said latch means are suitable to cooperate with each other by the effect of the rotating electric actuator, from this pre-locking position.

The locked position of a sheet requires a compression of the seals that are arranged between the sheet and the sleeper, that is, an effort that can be considerable. In addition, when the sheet is applied against the sleeper, the elasticity of the different seals of the sealing system tends to push the sheet out of the sleeper. However, it is necessary to keep the sheet applied against the sleeper for the time necessary for the lock to take effect, that is, the time for the latch means to be inserted into the strike means. The immobilization or locking of the sheet in a pre-locking position advantageously allows the operator to avoid having to maintain the compression of the sealing joints for the time necessary for the electric actuator to block the sheet. With the present feature, the operator can thus be content with bringing the sheet to the pre-locking position by a moderate and punctual effort that can also be supplied by the inertia of the sheet in its movement when it is pushed against the sleeper. Then, when the sheet is immobilized in this pre-locking position applied against the sleeper, the operator's effort on the sheet can be released by taking over the immobilization system and proceeding with the locking system assisted to automatically locking the sheet. or by means of a switch operated by the operator as the case may be.

According to an advantageous feature, the immobilization system of the sheet with respect to the sleeper in said pre-locking position comprises an elastic releasable locking means consisting of a first element fixed on the sleeper and a second element fixed on the sheet, said first cooperating and second elements to each other by means of an elastic friction connection in order to make at least one locking point of the sheet with respect to the sleeper in its position applied against the sleeper, suitable to be released by the effect of a pivoting force exerted on the sheet with a view to its opening.

A striking or analog device may, for example, be suitable for the implementation of this feature, as will be described below by means of an example of an embodiment of the invention. This hitting device can preferably be multiple and distributed transversely above and below the closing device and in the vicinity of the rotation upright, to form several locking points and ensure better retention of the blade in the closed and pre-locked position. .

According to an advantageous feature, the closing device according to the invention further comprises a leaf closing sensor, associated with one of the sleeper or leaf profiles, which cooperates with a stop on the other of the leaf profiles or of the sleeper when the leaf is applied against the sleeper, said leaf closing sensor being connected to the power circuit of the rotating electric actuator for:

- establish the continuity of the power supply circuit of the rotating electric actuator with a view to allowing its operation in this leaf position applied against the sleeper, and

- Cut this power supply circuit of the rotating electric actuator with a view to preventing its operation in an opening position of the blade not applied to the sleeper.

According to an advantageous characteristic, said leaf closing sensor is connected to the power circuit of the rotating electric actuator so that it sends a control signal of the electric actuator when activated by the sheet applied against the sleeper.

This closing sensor of known type can also be mounted and placed in the power supply circuit of the electric actuator, to be chosen, according to which of the following two functions it is to be attributed, depending on the needs:

- a functionality of the leaf closing sensor in contact with the sleeper and the combined safety switch of the actuator feed circuit,

- a functionality of the leaf closing sensor in contact with the sleeper and the simultaneous control of the locking system in the locked leaf position (blocking control); in this case, the closing sensor, when activated when the blade is applied against the sleeper, sends a signal that orders the lock to the electric actuator. According to this preferred functionality, the closing sensor is integrated in the control means of the electric actuator. Therefore, the operator does not have to operate the control means of the electric actuator to block the sheet, which become simple means of unlocking control and this automatically locks the sheet by pushing it against the sleeper, through the closing sensor .

Whatever the power supply system used for the electric actuator and whatever the functionalities chosen for the closing sensor, the latter prevents the eventual consequences of an untimely control of the actuator when the blade is not in the correct position for locking or pre-locking position, limiting at least the actuator power supply to the position of the sheet on which it should act. The closing sensor thus prevents the locking system from being damaged during an attempt to close the sheet when its locking system is in the locked position. Thus, advantageously, the power of the electric actuator only becomes effective when the blade is applied against the sleeper, when the blade closing sensor is activated. In all other leaf opening positions beyond said pre-locking position, the closing sensor is not activated and the power circuit of the electric actuator is thus open whatever the way of powering this actuator electrically; Under these conditions, even if the operator suddenly maneuvers the blocking switch, the electric actuator does not act on the locking system.

The closing sensor may be constituted by a tongue, lever or operating button contactor, of the end-of-stroke sensor type, fixed, for example, on a recess of the sleeper or of the blade, preferably the sleeper, whose lever or button is actuated by the leaf or the sleeper, respectively, preferably, the leaf, connected to the power circuit of the electric actuator according to the alternatives indicated above.

As mentioned above, the closing device according to the invention also comprises the ejection system of the sheet that passes the latter from its pre-locking position to a closed position by releasing the sheet from said immobilization system with respect to the sleeper in said preblocking position, which uses the movement of the striker means or the latch means during the unlocking of the blade.

The ajar position is qualified as such when the sheet has been ejected to a half-open or ajar position, beyond the locking system in the pre-locking position and remains close to this position. Once the unlocking is carried out, the sheet remains applied against the sleeper since the repulsive forces of the gaskets are generally insufficient to cause ejection of the sheet out of the immobilization system or locked in the pre-locking position. Advantageously, the ejection system guarantees the decompression of the sealing joints and the ajar of the sheet by forcing said locking immobilization system in order to allow the operator to grip this sheet, for example, by its periphery, to open it in its totality without more effort than the pivot of the blade. Thus, no maneuvering handle is necessary for opening the blade.

According to an advantageous feature, said leaf ejection system comprises an inclined ramp associated with the sleeper which cooperates with a stop formed in the latch means or the strike means associated with the sheet, during the movement of said latch means or said striker means from the locked position to the unlocked position, in order to force the pivoting of the blade to said ajar position during the unlocking thereof.

According to an advantageous characteristic, said stop formed in the latch means or the striker means associated with the blade, is constituted at least by a pin that protrudes from a sliding rod means that forms the latch means associated with the blade, which cooperates with the locksmith means associated with the sleeper, during the locking and unlocking of the leaf.

This feature advantageously uses elements of the existing locking and unlocking system to eject the sheet, giving these elements additional functionality.

Detailed description of the invention

The example of a device for closing a construction site according to the invention shown in the figures refers to a window and comprises:

- a sleeper 1 made by means of profiles 40,

- a practicable sheet 2 or swinging leaf, associated to the sleeper 1 by a pivoting connection 3 and made by means of profiles 14; it should be noted that the constituent profiles of sheet 2 have not been represented in Figure 1 to highlight the integrated locking system,

- a system 4 for locking and unlocking the sheet 2 in the sleeper 1, comprising at least one lock means 5 and at least one latch means 6 suitable for cooperating with the lock means 5 for locking the leaf 2 in the sleeper 1, preferably being the striker means 5 associated with the leaf 2 and preferably being the latch means 6 associated with the sleeper 1,

- means 7 for controlling the locking and unlocking system 4 comprising:

- a rotating electric actuator 8 disposed within a profile 14 of the sheet 2 and linked thereto, as will be explained below,

- a screw-nut type connection 9 disposed inside a profile of the leaf 2, to transform the rotary movement of the electric actuator 8 into a movement of the latch means 6 of the locking and unlocking system 4, which is associated with sheet 2,

- control means 10 of the rotating electric actuator 8, suitable for being operated by an operator at least for unlocking the blade.

The constituent profiles 40, 14 of the sleeper 1 and the sheet 2 are hollow section profiles, preferably conventional, for example, metal profiles of a light alloy and with thermal break, as shown in Figure 4. The profiles 40 of the sleeper 1 can have, for example, a conventional cross section comprising an L-shape that defines a recess of receiving the sheet 2, which will be used to house some organs of the closing device according to the invention as explain later. The sheet 2 advantageously has conventional profiles 14, complementary to the profiles 40 of the sleeper 1 to cooperate therewith with a view to making a device for closing a work space.

The locking and unlocking system 4 of the sheet 2 on the sleeper 1 advantageously is also conventional in the sense that the lock means 5 is formed, for example, by a plurality of metal pins fixed in the L-recess of the sleeper 1 distributed on one or more sides of the sleeper 1, as shown in Figure 1. As for the latch means 6, advantageously, it is also conventional and is formed in a known manner, for example, by a rod 32 sliding in the plane of the sheet longitudinally along the or of the profiles 14 of the sheet, and on which a plurality of pins 31 are fixed. The locking system 4 consists of as many pins 31 as of metal pins that they form the locks 5, a pin 31 being designed to be housed behind a metal pin to form a locking point, as shown in Figures 11, 12A and 13A. The locking of the sheet 2 in the sleeper 1 is carried out by the translational movement of the sliding rod 32 and the associated pins 31 which are to be positioned behind the strikes 5. The unlocking is carried out by the reverse displacement in translation of the sliding rod 32 and associated pins 31 that come to be positioned outside the strikes 5 so that, when the blade 2 pivots, the pins 31 are released from the strikes 5 and do not hinder the pivoting of the blade 2, as is he has represented in figures 12B to 12D and 13B to 13D. As shown in FIG. 1, the sliding rod 32, advantageously, can run continuously through the periphery of the leaf 2, except for the articulated side of the leaf 2 that supports the hinges 41, that is, by the three free sides of the blade 2, as shown in Figure 1, using angled gears 42 in a known manner.

The rotating electric actuator 8 is linked to a point of the sliding rod 32, through its motor shaft and the screw-nut connection 9, for example, at one end of the rod 32, specifically, located in the lower cross member of sheet 2, in the example shown in figure 1. In the example shown, the actuator 8 and the screw-nut connection 9 are thus integrated into the lower cross member of the sheet 2, as explained below.

As shown more particularly in Figures 2A to 2C and 3, the rotating electric actuator 8 advantageously has at least one drive shaft 11 which is coupled, through a coupling sleeve 50, to the aligned screw 12 of the connection 9 screw-nut type and is positioned so that its axis of rotation 13 is parallel to the longitudinal direction of the profile 14 in which it is arranged. The rotating electric actuator 8 can be constituted by any motor or electric motor-reducer, of elongated shape, either one or several, capable of sliding in an alveolus 43 or a longitudinal housing of the profile 14. For this purpose, the cross section of the electric motor, taken according to its outer perimeter, will be less than the cross section of the socket 43 defined by the walls thereof, as shown in Figure 4. The drive shaft of the actuator 8 should preferably extend according to the longitudinal direction of the body of the actuator 8 in order to obtain a motor shaft parallel or substantially parallel to the longitudinal direction of the profile 14. The sliding rod 32 provided with its pins 31 is fixed to the nut 15 of the screw-nut type 9 connection, according to any appropriate means, for example, directly or by means of a connecting rod, to move in translation following the longitudinal direction of profile 14 with nut 15, as shown in Figures 2A to 2C.

The rotating electric actuator 8, advantageously, is linked to the profile 14 of the sheet 2 on which it is arranged, by means of a connecting plate 16 on which the body 17 of the rotating electric actuator 8 is fixed and on which the connection 9 screw-nut type is placed. The screw 12 of the screw-nut connection 9 is rotatably mounted, with respect to the plate 16 being linked to the drive shaft as explained above and fixed in translation with respect to this plate 16. As for the nut 15 of the connection 9 screw-nut is mounted free in translation with respect to the plate 16 and fixed in rotation with respect to it.

Alternatively, the body of the actuator 8 could be fixed directly on the profile 14, but, preferably, it is linked to the profile by said intermediate plate 16 in order to ensure a longitudinal mobility of the assembly constituted by the actuator 8, the connection 9 nut- screw and associated locking rod 32, thanks to the mobility of the connecting plate 16, to advantageously provide the closure device shown, with an emergency manual locking and unlocking system, as explained above.

The actuator 8 is fixed on the plate 16 by its body by means of a fixing bracket 45, for example, and the end of the screw 11 opposite to the one coupled to the motor is also linked to the plate 16, but by means of a connection with a degree of freedom in rotation by means of a connection support 46 in order to ensure a good retention of the rotating screw 11 at its two ends. The nut 15 of the screw-nut connection 9 can be immobilized in rotation by the outer shape of its cross section, for example, a prismatic shape substantially complementary to the shape of the cross section of the housing in which the nut 15 travels in an exclusive movement of translation.

In Figure 2A, the locking system 4 is activated, the nut 15 is in distal support on the support 46.

In Figure 2B, the locking system 4 is deactivated, the nut 15 is in proximal support of the motor side 8. It is preferred that there are two stop springs (not shown) properly positioned in the two limit switches of the nut 15. The displacement of the nut 15 between these two extreme positions determines the path of the sliding rod 32 of the locking system. This path must represent at least the path necessary for the locking pins 31 to move from the locked position behind the strikes 5, to the unlocked position releasing the pins 31 from the struts 5. As developed later with the help of figures 13, advantageously this path also includes an additional displacement of the sliding rod 32 necessary for the ejection system 29 of the leaf 2.

In Figure 2C, the locking system 4 is deactivated, the nut 15 is represented in a substantially medium position between the two extreme positions of Figures 2A and 2B, which in the example correspond to an unlocking of the pins 31 and a ejection system 29 that has not yet taken effect.

Being the motorization system located in the mobile frame of the sheet, it is necessary to have a flexible power supply that allows to follow the movement of the sheet. Advantageously, this can be done by means of a sliding contact (not shown) located in recesses in the hinge post 41. Such sliding contact, for example, has the following composition:

- a first piece fixed to the sleeper consisting of two conductive terminals connected to the transformed power supply of the construction in which the closing device is located,

- a second piece fixed on the sheet consisting of two conductive fingers connected to the electric actuator 8 to be fed, which come into contact, respectively, in contact with the two conductor terminals of the sleeper when the sheet reaches the area of its position closing, for example, when it forms an angle of the order of 20 ° with the sleeper.

Thus, in the closed-leaf position, the actuator 8 is fed and, therefore, in operation and in the open-leaf position beyond 20 ° of opening, the actuator 8 is no longer fed, since the conductive fingers in contact with the conductive terminals. Other flexible feeding systems can be used, for example, a permanent feeding by flexible cables that pass through the articulated side in order to limit, even completely hide, the electric cables.

The closing device shown may consist of an electronic card (not shown) for power management and of the electric or electronic organs used, such as the electric actuator (s) 8, a closing sensor 29, as will be described in more detail. later, the control means 10 of the actuator 8, which is integrated in a hollow housing of the profiles.

As shown more particularly in Figures 2A to 2C, 3 and 5, advantageously, the control means 7 of the locking and unlocking system 4 further comprise an emergency mechanical system 18 suitable for maneuvering by an operator by means of an emergency manual control 19 in case of power failure of the rotating electric actuator 8.

As shown in Figure 5, the connection plate 16 is thus advantageously linked to the profile 14 of the sheet by means of a connection 44 consisting of a degree of freedom in translation along the longitudinal axis of the profile 14 and the plate 16 The connection is positioned so that it is mobile in translation along this longitudinal axis through the emergency manual control means 19, at least between the following three positions:

- a first position or middle rest position, in which the locking and unlocking system 4 is located in the locked or unlocked leaf position depending on whether the rotating electric actuator 8 has been operated in its locked or unlocked leaf position 2, respectively; This position is the normal operating position of the closing device represented with the assistance for locking and unlocking, as shown in Figure 6A, and

- a second position or active unlocking position, in which the locking and unlocking system 4 is located in unlocked leaf position 2, as shown, for example, in Figure 6B, the rotating electric actuator 8 being locked in its locked 2 leaf position, and

- a third position or active locking position, in which the locking and unlocking system 4 is located in locked leaf position 2, the rotating electric actuator 8 being locked in its unlocked leaf 2 position (position not shown).

The connection 44 consisting of a degree of freedom in translation of the plate 16 along the longitudinal axis of the profile 14 can be secured by means of a sliding fit of the cross sections of said plate 16 and of the socket 43 of the leaf profile 14 in the That has slipped.

As shown in FIG. 5, the emergency manual control means 19 comprises a pinion-rack type device 21 positioned such that the rack 22 is fixed to the connecting plate 16, which is mobile in translation, and that the pinion 23 is linked to the profile 14 by means of a connection with a degree of freedom in rotation. The rack 22 extends in the longitudinal direction of the profile 14 so that its displacement in translation due to the manual rotation of the pinion 23 drags the displacement in translation of the plate 16 according to this longitudinal direction of the profile 14. The pinion 23 is positioned so as to be arranged substantially in the middle of the rack 22 in the median resting position defined above, in order to allow a translational movement of the plate 16 inside the profile 14 in one direction and in the opposite direction to from this medium position, depending on whether the operator rotates the pinion in a direction of rotation or in the reverse direction, to put the emergency mechanical locking and unlocking system 18 in the second position or active unlocking position, or in the third position or active locking position, respectively, as defined above.

The pinion 23 is provided with a gripping means 24, for example, a square hole, suitable for cooperating with a tool 60, for example, a square type maneuvering wrench in the case of a gripping means constituted by a square hole , with a view to the rotation of the pinion 23 for maneuvering the rack 22. This pinion 23 is advantageously concealed under the control means 10 of the rotating electric actuator 8 suitable for being operated by an operator, as shown in Figure 7B, of the that a part is removable in order to access the emergency manual control means, in this case, the pinion 23.

For this purpose, the control means of the electric actuator suitable to be operated by an operator, advantageously, comprises a switch means 10, for example, a tactile switch, whose visible upper surface is inscribed in a window 20 made in an outer wall of a profile 14 of the sheet, as shown in Figures 6, 7 and 10. The visible upper surface of the switch means 10 is advantageously removable, to access the gripping means 24 located on the pinion 23, for example, by pressure if necessary and sliding, as shown in Figures 7A and 7B, or by snap-in (not shown). The pinion 23 is placed inside the contour of the window 20 and below the visible upper surface of the switch means 10.

In order that the emergency mechanical system 19 is not actuated in an untimely manner by the actuator 8 or by vibrations, for example, the rack 22 is immobilized with respect to the profile 14 by any means of detachable immobilization preferably by an obstacle, by For example, a locking screw 47, as shown in Figure 5, that the operator will have to unscrew to be able to maneuver the pinion 23.

The closure device shown in the figures, more particularly, in Figure 8, advantageously, also comprises a locking system 25 of the sheet 2 with respect to the sleeper 1 in a pre-locking position, in which the sheet 2 is applied against the sleeper 1 and is not locked, positioned so that said lock means 5 and said latch means 6 are suitable for cooperating with one another by the effect of the rotating electric actuator 8, from this pre-locking position.

Preferably, the immobilization system 25 of the sheet 2 with respect to the sleeper 1 in said pre-locking position comprises an elastic releasable locking means consisting of a first 26 element fixed in the sleeper 1 and a second 27 element fixed in the leaf 2 , these first 26 and second 27 elements cooperate with each other by means of an elastic friction connection in order to make a locking point by friction of the leaf 2 with respect to the sleeper 1 in its application position against the sleeper 1, suitable for release by effect of a pivot force exerted on sheet 2 with a view to its opening.

Such immobilization system 25 may be constituted by one or more locking points distributed in several locations around the frame of the sheet 2, preferably, towards the articulated side of the sheet supporting the hinges 41, as shown in Figure 1 A locking point is constituted, for example, by a device of known type, a knock, composed of a U-shaped spring element 26 and a complementary pin-like element 27 that fits into the spring element 26 by elasticity of the latter. Once fitted, the spring element 26 resumes its resting shape to imprison the pin element 27 inside. To remove the striking pin 27 from the striking spring element 26, it is sufficient to exert a tensile force on the striking pin 27 with a view to compressing the spring element 26 which returns to its resting form after the passage of the pin 27. The strokes 26, 27 as well as their positions in the profiles, will be selected so that once the pin 27 is placed in the spring element 26, the latter returns to its initial position and prevents the pin from coming out again, being its elasticity such that a force greater than that produced by the seals is necessary to deform it.

As shown in FIG. 9, advantageously, the closing device further comprises a closing sensor 28 of the leaf 2, fixed, in the example, within a recess in a profile 40 of the sleeper 1, cooperating with a stop formed in the sheet 2, preferably, directly, by a constituent profile thereof, when the sheet 2 is in the pre-locking position applied against the sleeper 1. Preferably, the closing sensor 28 of the sheet 2 is connected to the power supply circuit of the rotary electric actuator 8 to allow its operation in this pre-locking position by establishing the continuity of the power circuit of the rotating electric actuator 8 and preventing its operation in an opening position of the leaf 2 beyond the pre-locking position by cutting this circuit of feeding. Preferably, the sensor 28 assimilable to an end-of-stroke sensor, is placed in the upper part of the blade near a knock 26, 27 in order to ensure a good operation thereof regardless of the possible deformations of the blade, it is that is, in order to ensure the activation of sensor 28 in the pre-lock position. In addition, and always preferably, the limit switch sensor 29 is connected in the power supply circuit of the electric actuator 8 so that it sends an order when it is actuated in the pre-locked position of the blade applied against the sleeper, in order of executing the blade lock automatically without further action by the operator other than pushing the blade against the sleeper. Thus, advantageously, the sensor 29, in the example, is a constituent means of the control means of the electric actuator 8. The switch 10 therefore ensures in the example only a control function of the leaf release.

The closure device shown in the figures, more particularly, in Figures 8, 11 and 12, advantageously, furthermore comprises an ejection system 29 of the sheet 2 which passes the latter from its pre-locking position to a closed position releasing the leaf 2 of the immobilization system 25 with respect to the sleeper 1 in the pre-locking position, that is, in the example, releasing the leaf 2 from the knock (s) 26, 27. The ejection system advantageously uses the displacement of the latch means 6 during the unlocking of the sheet 2 as explained above.

The ejection system 29 of the leaf 2 comprises, for example, an inclined ramp 30 associated with the sleeper 1 cooperating with a stop 31 formed in the latch means 6 associated with the leaf 2, during the movement of this latch means 6 from the locked position to the unlocked position, in order to force the pivoting of the leaf 2, to the ajar position, during the unlocking thereof, transforming the displacement in translation of the sliding rod 32 into displacement in rotation of the leaf two.

The ejection system may comprise one or preferably several ramps 29 in order to distribute the release effort of the strokes 26, 27 through several points of the periphery of the sheet 2. The inclined ramp or 30 are fixed in the recess of the sleeper 1 near the struts 5 in order to advantageously use the pins 31 associated with the slide rod 32 at the same time for locking / unlocking the sheet 2 and as a stop for the ejection of the sheet 2. In addition, the or inclined ramps 30 are fixed in a recess of the sleeper 1 near the strokes in order to have a relatively direct and effective action on them, subtracting the possible flexibility of the profiles 14 of the sheet. An inclined ramp 30 may be materialized, for example, by a terminal fixed in the recess of the sleeper 1, as shown in Figures 11 and 12 so that a pin 31 associated with the ramp 30 is suitable for traveling the ramp by stop on this during the translational movement of the sliding rod 32, as shown in Figures 12B and 12C.

Thus, said stop formed in the latch means 6 associated with the sheet 2, preferably, is constituted by at least one pin 31 protruding from the sliding rod means 32 forming the latch means 6 associated with the sheet 2, cooperating with the lock means 5 associated with the sleeper 1, during the locking and unlocking of the sheet.

The operation of the ejection system is described below, with the help of Figures 13A to 13D: In Figures 13A to 13D, the sheet is symbolically represented by the sliding rod 32 with an associated locking pin 31 and by the pin 27 of the tap, these elements being attached to the sheet in the example shown; the sleeper is in turn symbolically represented by a strike 5, an inclined ramp 30 and the striking spring 26, these elements being attached to the sleeper. Next, the designation "sheet" refers in figures 13 to the symbolic elements that represent it, as defined above, and the designation "sleeper" also refers in figures 13 to the symbolic elements that represent it.

Figure 13A depicts the leaf in the closed and locked position on the sleeper: the locking pin 31 is behind the striker 5; in the alignment of the path of the pin 31, the inclined ramp 30 is seen which must intercept the pin 31 in its path and the hitting pin 27 that is shown beyond the ramp 30 and must not obstruct the path of the locking pin 31 which must be free between the strike and the inclined ramp 30. However, the punch 26, 27 will be arranged close to the ramp 30 so that the effect of the latter is as direct as possible with respect to the strike (suppression of eventual flexibility of the blade). In the locked position according to Figure 13A, the striking pin 27 is, of course, housed in the striking spring 26 and exerts its function of retaining the blade in a position applied against the sleeper, corresponding to the pre-locking position. The striking pin 27 remains, of course, in the striking spring 26 during locking and in the locked leaf position.

Figure 13B depicts the sheet in the unlocked position, after activation of the unlocking by the operator when the switch 10 is operated, the electric actuator 8 having made the rod 32 slide longitudinally with the locking pin 31 that will thus have left behind. of the lock 5 no longer retaining, therefore, the leaf in its closed position; the striking pin 27 is still housed in the striking spring 26, the sheet is still applied against the sleeper and the blade is still held, therefore, against the sleeper by means of the striking; It should be noted that Figure 2B also represents, in the reverse process of closing and locking the sheet, the sheet in the pre-locking position when it has just been applied against the sleeper and the closing sensor 29 has not yet activated the lock.

Figure 13C represents the sheet in the course of ejection: from Figure 13B, after unlocking the sheet, the electric actuator 8 remains activated and the rod 32 continues its longitudinal unlocking travel in a longitudinal ejection path of the sheet that takes over in the unlocking path, continuously, for example, until the locking pin 31 stops against the inclined ramp 30 of the ejection system 29, which is aligned in the path as shown. Then, since the sheet is no longer locked, the pin 31 continues its ejection path being forced by the ramp 30 according to a path component perpendicular to the plane of the sheet and in the opposite direction to the sleeper's swing, driving the pivoting of the sheet . This forced pivoting by the effect of the electric actuator 8 and according to said perpendicular trajectory causes the ejection of the striking pin 27 out of the striking spring 26 as a result of an elastic deformation of the latter, as shown in Figure 13C. When the striking pin 27 has been ejected out of the striking spring 26, the blade is ajar or ajar and the sliding rod 32 stops its ejection path. The operator only has to finish opening the blade according to his needs without more effort than swinging it around his joint.

Figure 13D depicts the ejected leaf ajar. After ejection of the sheet, the sliding rod 32 is brought back in the opposite direction to the position of Figure 13B corresponding to the pre-locking position, in order to place the locking system in position to operate the closing of the sheet , when the inclined ramp 30 is no longer opposed to this leaf closure. Figure 13D represents precisely this position of the locking system which also extends to the open sheet as it approaches the closure. If the operator wishes to close the sheet, he only has to apply it against the sleeper (figure 13B) causing the closing sensor to block the blade when the electric actuator 8 is actuated.

The present closing device is used for any type of sheet, for example, a door, window, French door, etc ...
