Description

Title of the invention: Mechanism for closing shutters and shutters fitted with such mechanisms.

FIELD OF THE INVENTION The subject of the present invention is a mechanism for closing a swinging or sliding shutter as well as a shutter or a pair of shutters equipped with such mechanisms.

STATE OF THE ART We already know multiple embodiments of closing mechanisms for swinging or sliding shutters. In general, these are latches installed on one of the flaps and which retains two swinging flaps, in the closed position, the second flap being retained by the joint cover carried by the first flap.

There are also Spanish type closing mechanisms with a rod provided with a pivoting and locking lever. This rod is terminated at both ends by a hook which hooks behind a fixed stop carried by the frame of the opening closed by the flap or flaps.

[0004] However, these various devices and mechanisms for closing the swinging or sliding shutter are attached to the flaps in a visible manner.

In some cases, the mechanism is a decorative and traditional element. But there is also a tendency consisting in making the accessories equipping a shutter as little visible as possible.

In addition, the shutter closing mechanisms such as the espagnolette mechanisms require adaptation to the dimension of the flap or flaps by modifying the length of the rods carrying the hooks which retain the flap or flaps.

Aim of the invention The aim of the present invention is to develop a shutter closing mechanism that is as simple as possible to make, install and adjust according to the dimensions of the leaf or leaves and allowing the if necessary, to be integrated into the thickness of the shutter so as not to be visible.

Disclosure and advantage of the invention To this end, the invention relates to a closing mechanism for swinging or sliding shutters characterized in that it comprises at least one bolt module with a bolt recalled by a spring and its keeper, the bolt module being fixed to the shutter and the keeper to the frame of the opening closed by the shutter, an operating module provided with an operating member and fixed to the shutter, a traction cable connecting the bolt to the operating member to pull the bolt against the action of its spring and release it from the strike.

The shutter or sliding shutter closing mechanism has the advantage of being particularly simple to produce and adapt to the dimensions of a shutter since the adaptation to the height of the shutter is done by simply adjusting the length of the cable connecting the operating module to the bolt module, whether it is a single module or two modules in more or less symmetrical positions.

This also makes it possible to adapt the height of the location of the maneuvering module to certain dimensional characteristics or practical requirements for shutters of a certain height which must nevertheless be easy to maneuver from a normal height d access to the operating module.

This is done by the free positioning at the appropriate access height and the simple adjustment of the length of the cable connecting the control module to the bolt module.

This shutter closing mechanism also has the advantage of being easily integrated into the thickness of a shutter since the means of transmission of the control movement from the operating module is a simple cable and the mechanisms both latch modules and the operating module are very simple, made up of a reduced number of parts.

The simplicity of the bolt module and of the operating module precisely because of the simplified connection between these two modules by a cable also makes it possible to reduce the size of these modules and to facilitate their integration into the thickness of the flap, for example, in a profile forming the partial or total framing of the shutter.

The mechanism according to the invention has the advantage of making the two bolt modules independent in the case of a high bolt mechanism, whether or not associated with the same operating module. Indeed, a fraudulent action on one of the bolts to neutralize it has no effect on the other bolt. It is therefore necessary to operate the two bolts at the same time, which complicates attempts to open the flaps.

According to a very advantageous characteristic, the operating member is a lever.

More particularly, the closing mechanism according to the invention is combined with a profile in which the module or modules are fixed.

According to this characteristic, a profile intended to border the flap on the side of the closure, the profile has a U-shaped section whose longitudinal opening corresponds to the edge of the flap and receives the bolt modules fixed near the ends in the profile and the operating module fixed to the profile in a chosen intermediate position, a cover closing the longitudinal opening of the profile and forming the edge of the shutter.

The integration of the bolt modules and the operating module in the profile facilitates the establishment of the mechanism on the shutter thus constituting a complete set capable of being distributed in this form of finished or semi-finished product.

According to an advantageous development, this mechanism is characterized in that the lying U-shaped section of the profile is formed by a crosspiece connecting two sides each formed of two large branches provided internally, each with a support rib at the same distance from the crossmember, the bolt module and the operating module have a plate formed by a base bordered at the longitudinal ends by two raised sides, the base being bordered on each longitudinal side by a lateral strip projecting from the base and inside the width of the sides, the base is traversed by at least one fixing screw screwed into the base inside its outline delimited by the two lateral bands and which, by screwing, protrude from below the base, the module being positioned by sliding it into the profile by its lateral bands under the support ribs on the side facing the cross member and then compressing, in position , the base by its lateral bands under the ribs, the screws pressing against the crosspiece to block the module.

This very simple structure of the profile, the bolt module and the maneuvering module allows a very advantageous and space-saving combination in the form of a profile which is part of the flap, whether it is a shutter or a sliding shutter.

According to another advantageous characteristic, the base has two screws offset longitudinally relative to the bolt / spring of the bolt module or to the pivot and to the pivot zone of the branch and of the extension of the module operating lever. The fixing by two offset screws distributes the forces applied by the operation of the module and the pulls exerted by the cables.

According to another advantageous characteristic, the profile has two large branches extended by small branches opposite the large branches with respect to the cross member in an H section, in which the U section formed by the small branches and the crosspiece covers the side of a leaf panel, the crosspiece being split to form a housing receiving a branch of an assembly bracket joining two sections cut at the tab to a corner of the leaf panel.

This form of section facilitates the combination of the mechanism of the panel of the flap or then sliding shutter in this mechanism, in a particularly advantageous manner, the bolt module comprises: a plate formed by a fixing base, the longitudinal ends of which have raised sides curved at right angles to receive the bolt, the rod of which slides, locked in rotation, in the raised sides, a return spring surrounding the body of the bolt between the raised sides and resting on the one hand on the sides and on the other hand, on the bolt to push it into the locking position with the strike, the two ends of the bolt each protruding from the raised side, in the deployed position and in the retracted position of the bolt, one of the two ends having a ramp and the other, a cable fixing means.

According to the invention, the maneuvering module comprises a plate with a base carrying the pivot of the maneuvering lever whose arm is engaged on the pivot by a pro long passing through the pivot to be provided on either side of the pivot in diametrically opposite positions, of a fastening clip for the end of a cable connected to a bolt, the axial direction of the fasteners not being aligned with the direction of traction of the cable at the end of the deployment stroke of the bolt.

Finally, according to another advantageous characteristic, the keeper is a plate provided with a cutout for receiving the nose of the bolt, bordered by a raised stop, provided with a damping element.

According to another advantageous characteristic of the operating module, its plate has a longitudinal side at a distance from the base which corresponds at least to the thickness of the support ribs on the top of the base with a side plate forming a headrest having an opening for the passage of the operating lever and its arm.

In summary, the shutter or sliding shutter closing mechanism according to the invention is distinguished by a simple and effective embodiment of the various elements making up the mechanism.

This mechanism is also installed very simply in a shutter or shutter panel, using the profile bordering the shutter.

The positioning of the modules in the profile is very simple and can also be adjusted on the spot to take into account certain features of an opening and the position of the strikes.

The positioning of the different elements is done by sliding them in the profile and blocking the position by tightening the screws carried by the plate of each module.

These various means are perfectly accessible to facilitate and simplify the adjustment and installation.

The installation of the cables connecting the bolt module to the maneuvering module is done just as simply as the installation of a bicycle brake cable.

Finally, the simplicity of the construction and of the connection between the operating module and the bolt modules, is also a guarantee of the proper functioning and reliability of the mechanism.

The invention also applies to the shutter fitted with such a mechanism, whether these shutters are simple or in pairs and whether they are pivoting or sliding.

Description of embodiments of the invention [0057] Figure 1 shows in its parts IA, IB, IC, a set of two shutters VI, V2, pivoting about a vertical axis Z1Z1, Z2Z2 according to the arrow A. These flaps VI, NI shown in the closed position are equipped with a closing mechanism embedded 100 in one VI of the flaps (main flap) and cooperating with two strikes 4 fixed to the opening of the opening, not shown , in its upper part and its lower part.

According to Figure IA, the built-in closing mechanism 100 is hidden from view both on the outside and on the inside where only the handle 211 of the operating member in the form of an operating lever 21 is visible surface. The main flap VI is hooked by its top and bottom bolts 11 in a respective keeper 4 into which they penetrate during the closing movement by their ramp 112 resting against the outer edge of the keeper 4 to retract elastically against the spring 113 for each bolt. The strikes 4 also have closing stops 42 defining the closed position of the two flaps VI, V2, the main flap retaining the other flap by its outer joint cover Cj (visible in FIGS. 6B, 6C).

The closing mechanism 100 fitted to the main flap V1 is shown in front view in Figure 1B and in side view in Figure IC.

These two views correspond; the front view shows the mechanism 100 seen by transparency from the inside of the shutter VI and FIG. 1C shows the mechanism seen by transparency through the edge of the edge of the shutter VI.

The mechanism 100 consists, in addition to the strikes 4, of a top bolt module 1 and a bottom bolt module 1 identical as well as a maneuvering module 2 with a pivoting operating lever 21, embedded .

The modules 1 have spring bolts 11; the bolts 11 are each connected by a cable 3 to the operating lever 21. The actuation of the lever 21 in the direction of the arrow O pulls on the two cables 3 and retracts the bolts 11 which are released from the strikes 4 and allow the opening of the shutters.

Figures IB and IC show the ramp 112 of each bolt 11 whose orientation is that adapted for a pivoting flap (arrow A). In the case of a sliding shutter, the bolt is simply rotated by 90 ° so that its ramp 112 allows the passage of the bolt meeting the lateral side of the keeper 4 (movement according to arrow B).

The closing mechanism 100 will be described using FIGS. 2 and 3 and its installation in the shutter will be described using FIG. 4.

Figures 2 and 3 are limited to the presentation of a bolt module 1 and the operating module 2.

The bolt module 1 consists of a plate 12 with a U-section with a rectangular base 121 provided with two raised sides 122. The bolt 11 has a body 111 in the form of a rod of non-circular section, for example a square section, so as to slide in two mortises of corresponding section in the two raised sides 122. The end 11 la of the bolt 11 ends in the ramp 112. The body 111 is surrounded by a helical compression return spring 113 pressing at one end against a raised side 122 of the plate 12 and at the other, against a stop 114, for example a washer secured to the body 111 of the bolt 11.

The end 111b of the rod 111 is integrally connected to the end 31 of a cable 3 by a non-detailed fixing means.

The bolt 11 is shown in the deployed position in Figure 2A and in the retracted position in Figure 2B.

The base 121 of the plate 12, between its two raised sides 122, is provided with two screws 123, preferably headless screws with a screw socket such as a slot or a hexagonal cavity; they are in positions offset with respect to the axis ZZ of the bolt 11 to serve for its attachment to the flap by means of a profile.

The rectangular shape of the base 121 extends laterally from the raised sides 122 by a projecting strip 124 for fixing the module 1 in a profile 5 with a U-section forming the edge or edge of the flap VI and housing this closing mechanism 100 as will be described with the aid of FIG. 4.

The operating module 2 consists of a plate 22 also with a U-section, formed of a rectangular base 221 bordered by two raised sides 222. The base 221 has a pivot 225 carrying the arm 212 of a lever operating 21 via an extension 213 passing through the pivot to exceed diametrically and carry two fasteners 214a, b in diametrically opposite positions to fix the end 32 of each of the cables 3 coming from the two bolt modules L These fasteners 214a, b are for example constituted by bores provided with a clamping screw to receive the cables 3 in the manner of fixing an electric cable in a domino.

The plate 22 is provided with a side or face plate 23 having an oblong opening 231 for the passage of the operating lever 21 and delimiting a housing 232 behind the opening 231 to receive the handle 211 of the lever in a protected manner maneuver 21 while preventing contact with the cable 3/32.

The operating module 2 is locked in position in the profile 5 by two screws 223 screwed into the base 221 of the plate 22.

The raised sides 222 at each end of the base 221 are each provided with a guide hole 222a of the cable 3 so as to keep the cable in the axis ZZ going until it is fixed to the bolt IL [0076] The diametrical direction of the two fasteners 214a, b is oriented relative to the direction of the handle 211 of the lever 21 so that the positions of the lever 21 and those of the bolts 11 correspond and preferably maintain the cables 3 in tension by the spring of the bolt modules 1 in the end position which is the locked position of the bolts 11a, b.

The fasteners 214a, b for fixing the two cables 3 to the extension 213 of the lever 21 are not located in alignment with the axis ZZ when the operating lever 21 is at rest so as to maintain a certain applied tension cables 3 by the return spring 113 of each bolt 11 and press the lever 21 against the side plate 23 of the plate 22 in the retracted position.

The plate 22 has a pivoting stop 226 against which comes the edge of the operating lever 21 in its unlocking position of the bolts 11 (Figure 2B).

The implementation of the operating module 2 shown in the sectional view of the section 5 in Figure 2C combined with Figure 2B is done as that of the bolt module 1 and will be described using Figure 4 .

The side views of the mechanism 100 in Figures 2A, 2B show the maneuver between on the one hand, the locked position of the bolt 11 and the lever 3 retracted from Figure 2A and on the other hand, the unlocked position of the bolt 11 and the lever 3 deployed (Figure 2B) while the front views of the mechanism 100 in Figures 3A, 3B allow to see the arrangement of the mechanism without highlighting the maneuver. The front views (Figures 3A, 3B) show in section the profile 5 and the mounting of the mechanism 100 as it appears in section in Figure 3C and will be detailed below.

Figure 4, in its parts 4A, 4B, 4C, shows the section 5 receiving the operating module 2 and the bolt modules L [0082] The section 5 (Figure 4A) is a section with an H section, the two sides 51 are connected by a double crosspiece 52 forming an assembly housing 53 to receive an assembly key 6 in the form of a square, one of the branches 61 of which is engaged in the housing 53 and the other branch 62 is engaged in a similar housing 53, of the profile on another side of the flap.

The small branches 51b of the sides 51 and the crosspiece 52 form a U-shaped section coming to cover the side of the panel of the shutter thus surrounded on its other sides by the profiles 5 assembling according to sections at the tab at 45 ° .

The large branches 51a of the sections 51 are those facing outwards from the flap; the lateral profile, opposite the profile provided with the hinges of the flap, receives the mechanism 100 and for this it has two support ribs 53 and two clipping ribs 54 at the end to receive a cover 55 by clipping.

The two support ribs 53 serve to receive the modules 1, 2 which are put in place by sliding and locking. Each module 1, 2 is slid with its plate 12, 22 behind the two support ribs 53 by its projecting lateral strips 124, 224 which come behind the support ribs 53 between which the raised sides 122, 222 of reduced width can pass. The module 1, 2 is introduced in this position from one end of the profile 5, its locking screws 123, 223 being retracted. By sliding, the module 1, 2 is placed in the appropriate position in which it is blocked by screwing the screws 123, 223 against the cross-member 52, the lateral strips 124, 224 being pushed against the underside of the ribs 53.

This installation is done preferably starting with a latch module 1 or the operating module 2 whose position is defined by the cutout 231 not shown here, through which the operating lever 21 is passed to install it on the pivot 225 of the plate 22 which, for its part, was introduced by one end of the profile 5.

Then the two bolt modules 1 are installed, they are blocked and the cables 3 are put in place between the bolts 11 and the fasteners 214a, b on the operating module 2. When the mechanism 100 is installed, we cover this cavity with the cover 55 clipped.

The cover 55 is not accessible when the flaps VI, V2 are closed since the edges of the two flaps face each other and thus protect themselves by preventing access to the cover 55.

Figures 4B, 4C show an assembly key 6 of the profiles 5, one (61) of the branches is engaged in the housing 52a and the other (62) is pending.

FIG. 5 shows the assembly of a shutter V composed of a panel P surrounded by four sections segments 5 cut at the tab and held assembled by keys 6.

FIG. 6 shows in its FIG. 6A, a front view, internal side of the flaps VI, V2 closed and in its FIG. 6B, a top view with the upper or lower keeper 4.

The view on an enlarged scale of the detail in FIG. 6C shows the support of the two flaps VI, V2 against a flexible stop 43 on the side opposite to that corresponding to the support of the bolt 11.

The second flap V2 is held by the joint cover profile Cj carried by the flap V1 equipped with the mechanism 100.

The sectional view of Figure 7A shows the support of the flaps VI, V2 against the flexible support elements 43 at the top and bottom. These elements 43 are carried by the stop 42 of the strikes 4, for example clipped into the holes of the strikes.

FIG. 7B shows on an enlarged scale how the bolt 11 is engaged in the cutout 41 of the keeper 4 and the support 43 clipped elastically into the curved tab of the keeper forming the stop 42.

The mechanism 100 is simple to manufacture and install on a shutter either directly on the profile 5 before its assembly with the panel forming the shutter, or after its assembly on the panel P.

Intervention on the control mechanism 100 is easy after unclipping the cover 55 since the modules 1 and 2 are perfectly accessible.

The detailed description above of an example of a shutter applies under the same conditions to swing shutters and sliding shutters, single or double.
