Description

Title of the invention: System for holding a movable leaf technical field

[0001] The present invention relates to the field of shutter closures, in particular devices for locking a shutter in the open position. It is particularly applicable to hinged shutters. STATE OF THE ART

[0002] In the field of joinery, there are many devices for holding a leaf in position against a wall, for example against a wall, the leaf allowing to obstruct an opening in a wall where for example a window is located.

[0003] Technical solutions exist for holding devices that keep the door leaf fixed relative to the wall and whose locking mechanism is directly accessible from the opening. These holding devices generally include a locking portion configured to cooperate by wedging with a strike plate fixed relative to the wall. The cooperation between the locking portion and the strike plate is controlled via a transmission element whose length is adjusted to the size of the door leaf.

[0004] These types of devices have the particular disadvantage of requiring a retaining device whose transmission length depends on the dimensions of the door leaf and the positioning of the strike plate. This necessitates the production of custom-made equipment, which can prove costly.

[0005] In order to address this problem, document FR3129966A1, illustrated in [Fig.1], provides for a device comprising a portion fixed to the leaf and a mobile portion, the mobile portion being able to be adapted easily and at a lower cost to all leaf dimensions.

[0006] However, this type of device has the disadvantage of requiring drilling in several places through the door leaf itself for installation. Installing such a device implies potential damage to the door leaf and therefore malfunction of the device.

[0007] An object of the present invention is therefore to propose an optimization of a system allowing a fixed leaf to be kept relative to the wall.

[0008] The other objects, features, and advantages of the present invention will become apparent from an examination of the following description and accompanying drawings. It is understood that other advantages may be incorporated. SUMMARY

[0009] To achieve this objective, according to a first aspect, a system for retaining a movable leaf relative to a frame is provided, the system comprising a hinge having at least one first through hole, preferably at least one first and one second through hole, suitable for receiving a first fixing element so as to fix the hinge to a leaf, and a retaining device comprising a fixed portion suitable for being fixed to a leaf, and a movable portion, the movable portion comprising: • a control portion comprising a transmission element extending along a principal direction of extension, • a blocking portion integral in movement with the control portion such that the blocking portion is controlled in movement by the control portion, the blocking portion being configured, in a locking configuration, to prevent movement of a leaf relative to a frame, and the control portion being capable of being manually actuated so as to move the holding device from the locking configuration to an unlocking configuration of a leaf relative to a frame, characterized in that the retaining device is positioned on one face of the hinge and in that the retaining device includes at least one through opening located in correspondence with the first through hole so as to fix the hinge and the device together by the first fixing element on a leaf.

[0010] Thus, the system can be installed easily and without additional drilling of a window sash. Indeed, using the pre-existing holes of a hinge to attach the retaining device avoids unnecessary damage to a window sash. Furthermore, installing on a hinge with existing characteristics reduces the cost, time, and complexity of the system installation. Finally, this system can be installed on existing window frames by reusing the existing hinge holes, eliminating the need to purchase new hinges for existing shutters.

[0011] According to another aspect, a method for fixing the system to a leaf having a transverse dimension is provided, comprising: • the positioning of a hinge on a door leaf, the hinge extending along the transverse dimension of a door leaf and having at least one through hole, • an alignment of at least one through-opening of the retaining device with at least one through-hole of the hinge, the retaining device having its extension dimension parallel to the transverse dimension of a leaf, • a fixing of the retaining device and the hinge via the same fixing element configured so as to fix the device and the hinge to a leaf in a common way.

[0012] Thus, the installation process is simplified. The use of existing holes allows for easy installation of the device on the hinge. Furthermore, an installer does not need any special tools to install the system. The combination of the hinge and the retaining device creates a very cohesive and robust assembly.

[0013] Another aspect relates to an assembly comprising a leaf and the system.

[0014] Thus, the system can be present directly on shutters to be installed.

[0015] Alternatively, a building opening is provided comprising a peripheral structure delimiting a passage and the whole.

[0016] Thus, the system can be installed on any leaf, whether it is for example a window leaf or a door leaf or a French window leaf. BRIEF DESCRIPTION OF THE FIGURES

[0030] Before beginning a detailed review of embodiments of the invention, optional features which may possibly be used in association or alternatively are stated below.

[0031] According to one example, the fixed portion includes a guide relay, the guide relay having a through-hole in a direction perpendicular to the main extension direction, positioned so as to be aligned with the first through-hole of the hinge so as to jointly fix the hinge and the device by the first fastener. Fixing at least part of the fixed portion of the device to a pre-existing hole in the hinge with a single common fastener allows the reuse of existing holes in a hinge already in place. This facilitates installation while limiting costs.

[0032] According to one example, the fixed portion comprises a protective housing, the protective housing having a main through-hole in a direction perpendicular to the main extension direction, positioned so as to be aligned with a second through-hole in the hinge so as to jointly fix the hinge and the device by a second fastener. Fixing at least one other part of the fixed portion of the device to a pre-existing second hole in the hinge with a single common fastener allows the reuse of existing holes in a hinge already in place. This simplifies installation while reducing costs. Furthermore, the use of two spaced holes allows for robust fixing across the transverse dimension of a door leaf.

[0033] According to one example, the protective housing has additional through-holes, and the hinge has additional through-holes. These additional through-holes and through-holes are configured to be paired in correspondence so as to jointly fix the hinge and the device by means of additional fasteners. In one embodiment, this allows for robust fixing of the retaining system to a door leaf in a vertical direction. This provides a better grip on the hinge at the strike plate, thus improving strength in the locked position.

[0034] According to one example, the first, second, and additional fasteners are chosen from among screws or rivets. Each of the fasteners can therefore be universal and facilitate the installation of the device.

[0035] According to one example, the system comprises a strike plate with a longitudinal dimension, the strike plate being positioned on a frame with its longitudinal dimension along the principal direction of extension and configured to cooperate by means of an obstacle with the holding device in the locked position. The longitudinally positioned strike plate allows a portion of it to be in direct contact with the hinge and no portion to be in direct contact with a door leaf. Thus, the direct contact with the hinge, which may be made of metal, prevents damage to a door leaf when switching to the locked position without the need for an additional protective base. The number of parts is therefore limited, consequently reducing the cost and difficulty of installation.

[0036] According to one example, the transmission member includes at a first end a gripping element configured to allow manual control of the control portion. This allows it to switch to an unlocked configuration when the device is hinged.

[0037] According to one example, the gripping element is an additional part having a groove configured to fix the additional part onto the transmission member, and wherein the additional part has two gripping areas positioned on either side of the groove so as to manually grasp the retaining device. This allows for easy installation of the moving part of the device onto the fixed part of the device installed on the hinge and consequently facilitates the installation of the system on the hinge. Furthermore, alternatively, the ergonomics of this additional part allow the system to be easily unlocked despite the curvature of the hinge.

[0038] According to one example, a step of fixing the strike plate to a frame is carried out after the step of fixing the retaining device and the hinge, such that the longitudinal dimension of the strike plate is parallel to the main extension direction of the retaining device. The strike plate is thus only in contact with the retaining device and / or with the hinge. This prevents the strike plate from coming into contact with a door leaf, thus avoiding damage to the latter when switching from an unlocked to a locked configuration.

[0039] According to one example, a step of positioning the strike plate using a template is carried out before the step of fixing the strike plate. The template makes it possible to mark the wall to facilitate the positioning of the strike plate and thus facilitate the installation of the system.

[0040] According to one example, the strike plate is fixed using a strike plate fixing element. The strike plate fixing element may be a screw. This eliminates the need for additional tools to install the system.

[0041] The term "first and second faces of the door leaf" refers to the principal faces, that is, the opposite faces that are the most prominent. The first and second faces should be understood as the most prominent faces of the smallest possible parallelepiped in which the door leaf is inscribed.

[0042] In the following description, the term "on" does not necessarily mean "directly on." Thus, when it is stated that a part or component A is supported "on" a part or component B, this does not mean that parts or components A and B are necessarily in direct contact with each other. These parts or components A and B may be either in direct contact or supported by each other via one or more other parts. The same applies to other expressions such as, for example, the expression "A acts on B," which may mean "A acts directly on B" or "A acts on B via one or more other parts."

[0043] In this document, the term mobile or movement corresponds to a rotational movement or a translational movement or a combination of movements, for example the combination of a rotation and a translation.

[0044] In this document, when two parts are described as distinct, it means that these parts are separate. They are: • positioned at a distance from each other, and / or • mobile relative to each other and / or • joined together by being fixed by added elements, this fixing being removable or not.

[0045] A single-piece unit cannot therefore be made up of two separate parts.

[0046] In this document, the term "fixed" used to describe the connection between two parts means that the two parts are linked / fixed to each other with respect to all degrees of freedom, unless explicitly specified otherwise. For example, if it is stated that two parts are fixed in motion along a direction X, this means that the parts can be mobile relative to each other except along the direction X. In other words, if one part is moved along the direction X, the other part moves in the same direction.

[0047] In the present document, an elastic means may for example be a spring, such as a coil spring, elastic washers such as Belleville washers, an elastomer, a rubber.

[0048] In this document, a longitudinal dimension shall be understood as the longest dimension of the object.

[0049] In the detailed description that follows, terms such as "horizontal," "vertical," "longitudinal," "transverse," "upper," "lower," "top," "bottom," "front," "rear," "interior," and "exterior" may be used. These terms should be interpreted relatively in relation to the normal position of the retaining device and / or the door leaf and / or the wall. For example, the term "transverse" refers to the width of the door leaf.

[0050] In the prior art and as illustrated in [Fig. 1], a retaining device 1 is generally suitable for being positioned on a leaf 2. Preferably, in an opening configuration, a leaf 2 has a face opposite a wall of a frame 3 located next to an opening. That is to say, having a face opposite a wall of a frame 3, the retaining device 1 is located between a leaf 2 and the wall of a frame 3.

[0051] Just as in the prior art, the system for holding a movable leaf 2 relative to a frame 3 illustrated in figures 2 and 3 is suitable for being positioned on a leaf 2.

[0052] The holding system advantageously comprises at least one hinge 5 (and typically at least two). The hinges are parallel to each other and vertically spaced, with one hinge 5 lower and another higher. The hinge 5 may be a right-angle hinge. The hinge 5 allows a leaf 2 to be securely suspended and to open. Thus, the hinge 5 extends longitudinally along the transverse dimension of a leaf 2. It includes a node for creating a pivot connection with a pin fixed to the frame.

[0053] The hinge 5 visible in [Fig. 2] includes at least one first through hole 5a. The first through hole 5a is suitable for receiving a first fastener 6a. Thus, the passage of the fastener 6a through the first through hole 5a allows the hinge 5 to be fixed to a leaf 2. Preferably, the hinge 5 includes a second through hole 5b. The second through hole 5b is located away from the first through hole 5a, preferably along a direction Xn4 described below.

[0054] The holding system includes a holding device 1. The holding device 1 includes a movable portion. The movable portion of the holding device 1 allows a user to unlock a leaf 2 in order to close it.

[0055] The moving portion then comprises a control portion 11. The control portion 11 comprises a transmission member 114 extending along a principal extension direction Xn4. The principal extension direction Xn4 is parallel to the longitudinal dimension of the hinge 5. The control portion 11 is capable of being manually actuated so as to move the retaining device 1 from the locking configuration to an unlocking configuration of a leaf 2 relative to a frame 3. Actuation of the control portion 11 by a user causes the transmission member 114 to translate along the main extension direction Xn4. Preferably, the transmission member 114 comprises a metal rod that may have a rectangular cross-section; more preferably, the transmission member 114 comprises a profile with a solid rectangular cross-section. The transmission member 114 is then configured so as to be able to be assembled with a locking portion 112.

[0056] Thus, the moving portion also includes a blocking portion 112. The blocking portion 112 is fixed in motion to the control portion 11 such that the blocking portion 112 is controlled in motion along the main extension direction Xn4 by the control portion 11. Without limitation, this description may describe a translational movement, the translational movement being replaceable by a rotational movement about an axis perpendicular to the main extension direction Xn4. This may be a horizontal or diagonal translation relative to the ground. The blocking portion 112 is configured, in a locked configuration, to prevent the movement of a leaf 2 relative to a frame 3.

[0057] Advantageously, the control portion 11 is located at a first end of the retaining device 1 and the locking portion 112 is located at a second end of the retaining device 1. Preferably, the second end is at the opposite extreme from the first end. Preferably, the translational movement of the locking portion 112 occurs in conjunction with the movement of the control portion 11, along a direction connecting the first end to the second end and in the direction from the locking portion 112 towards the control portion 11.

[0058] The retaining device 1 is thus structurally configured to allow the retaining device 1 to move from a locking configuration to an unlocking configuration of a leaf 2 relative to a frame 3.

[0059] The retaining device 1 is positioned on one face of the hinge 5. Thus, one face of the hinge 5 is in contact with a leaf 2 and another face, opposite to the first, is in contact with the retaining device 1.

[0060] The retaining device 1 includes at least one through opening 1151, also called the relay through opening 1151. The relay through opening 1151 is located opposite the first through hole 5a so as to allow the hinge 5 and the retaining device 1 to be fixed together by the first fastener 6a on a leaf 2. This common fixing of the hinge 5 and the retaining device 1 facilitates the installation of a remote locking system without drilling. additional in a leaf 2. In addition, this allows to reduce the material required for the installation of device 1.

[0061] More specifically, the retaining system includes a fixed portion suitable for being fixed to a leaf 2. At least a part of this fixed portion will now be described with reference to Figures 4A and 4B.

[0062] According to one example, the fixed portion includes a guide relay 115. The guide relay 115 can be configured to be fixed rigidly to a leaf 2. To this end, the guide relay 115 can include a through-opening 1151 in a direction perpendicular to the main extension direction Xn4. This through-opening 1151 can then be positioned to align with the first through-hole 5a of the hinge 5 so as to jointly fix the hinge 5 and the device 1 by the first fastener 6a. Fixing at least part of the fixed portion of the device 1 to a pre-existing hole in the hinge 5 with a single common fastener allows the reuse of existing holes in a hinge 5 that may already be in place. This simplifies installation while reducing costs.

[0063] According to one example, the guide relay 115 includes an opening configured to allow the transmission member 114 to slide relative to a wall of a frame 3 and thus facilitate its translational guidance. The guide relay 115 further includes a protective surface configured to come into contact, in a locking configuration, with a wall of a frame 3 in order to stop the rotation of a leaf 2 relative to the wall of a frame 3 without damaging the wall's coating.

[0064] At least one other part of the fixed portion and a part of the moving portion will now be described with reference to Figures 5A and 5B.

[0065] According to one example, the fixed portion comprises a protective housing 113a. The protective housing 113a includes a main through-hole 1131 in a direction perpendicular to the main extension direction Xn4. The main through-hole 1131 can then be positioned so as to be aligned with a second through-hole 5b of the hinge 5. Thus, the alignment of the main through-hole 1131 and the second through-hole 5b of the hinge 5 allows the hinge 5 and the retaining device 1 to be fixed together. For this purpose, the fixing can be achieved by means of a second fixing element 6b. Fixing at least one other part of the fixed portion of the device 1 to a pre-existing second hole 5b of the hinge 5 with a single common second fixing element 6b allows the reuse of an existing hole 5b of a hinge 5 already in place. This facilitates installation while limiting costs.Furthermore, the use of the first 5a and second 5b through holes which are spaced apart allows for a robust fixing on the transverse dimension of a leaf 2.

[0066] According to one example, the protective housing 113a also includes a helical spring, the protective housing 113a being configured so as to allow constrained movement of the locking portion 112 relative to a strike plate 4.

[0067] Advantageously, when the control portion 11 is moved away from a strike 4, preferably under the actuation of the control portion 11 by a user, an element of the protection box 113a is constrained in compression and is configured to return to its initial configuration as soon as it is no longer constrained.

[0068] Advantageously, the protective housing 113a is protected by a housing 113.

[0069] According to one example, the fastening elements 6a, 6b are taken from among screws or rivets. Each of the fixing elements can therefore be universal and facilitate the installation of device 1.

[0070] According to one example, the transmission member 114 includes at a first end a gripping element 111 configured to allow manual control of the control portion 11. This allows switching to the unlocked configuration when the device 1 is on hinge 5.

[0071] According to one example, the gripping element 111 is an additional part 111 having a slide 111c configured so as to fix the additional part 111 onto the transmission member 114. More specifically, the additional part 111 can be fixed by clipping onto the transmission member 114. Similarly, the additional part 111 can be fixed onto the first end of the transmission member 114. Thus, the additional part 111 can then be integral with the transmission member 114.

[0072] According to one example, the additional part 111 has two gripping areas 111a, 111b positioned on either side of the slide 11 so as to allow the retaining device 1 to be grasped manually. More specifically, the two gripping areas 111a, 111b are configured so that a user can grasp them with two fingers. The two gripping areas 111a, 111b may be protruding protrusions. This allows for easy installation of the moving part of the device 1 onto its fixed part installed on the hinge 5. Thus, this facilitates the installation of the system on the hinge 5. Furthermore, alternatively, the ergonomics of this additional part 111 allow the system to be easily unlocked despite the curvature of the hinge 5.

[0073] According to one example, the system includes a strike plate 4 illustrated in Figures 6A, 6B, and 6C. The strike plate 4 may then have a longitudinal dimension. The strike plate 4 may be positioned on a frame 3 with its longitudinal dimension along the principal extension direction Xn4. The strike plate 4 may then be configured so as to cooperate by way of obstacle with the retaining device 1 in the locked configuration. The strike plate 4 may be positioned longitudinally so as to have a portion of it directly in The hinge 5 makes contact with the hinge, and no portion comes into direct contact with a leaf 2. This direct contact with the hinge 5, which can be made of metal, prevents damage to a leaf 2 when switching to the locked configuration without the need for an additional protective base. This limits the number of parts required, consequently reducing the cost and complexity of installation.

[0074] According to one example, the strike plate 4, advantageously fixed to the wall of a frame 3, is configured to cooperate with the locking portion 112. The strike plate 4 advantageously includes a cooperation portion 4b, comprising an opening configured so that the locking portion 112 can be inserted into it and abut against it under the action of an external force to hold a leaf 2 in an open position and advantageously parallel to the wall of a frame 3. More precisely, the cooperation portion 4b can be configured to allow sliding of the control portion 11. Advantageously, this will involve sliding a beveled surface of a beak 112a of the locking portion 112. The cooperation portion 4b can extend longitudinally along the continuity of the longitudinal dimension of the strike plate 4.

[0075] According to one embodiment, during a locking phase of a leaf 2, the beveled surface of the beak 112a is configured to cooperate by sliding, in contact with the cooperation portion 4b until the beak 112a reaches the level of the wedging portion. In one example, the cooperation portion 4b acts as a latch.

[0076] Preferably, the strike plate 4 includes an adjustment portion 4a configured to allow lateral adjustment of the strike plate mounting 4 relative to the wall of a frame 3. This may in particular be an oblong hole configured to position a screw.

[0077] According to one example, the strike plate 4 includes a bearing portion 4c configured so as to stop a leaf 2 against the stop and thus prevent it from touching the wall of a frame 3. The bearing portion 4c can then come into contact with the hinge 5. The bearing portion 4c is made of polymer or rubber.

[0078] According to one example, the strike plate 4 includes a system of removable shims so as to allow easy adjustment with the stroke of the locking portion 112.

[0079] Alternative embodiment:

[0080] According to an example illustrated in [Fig. 7], the protective housing 113a has additional through-holes 1132. And, correspondingly, the hinge 5 has additional through-holes 5c. The additional through-holes 1132 and the additional through-holes 5c are configured so as to be placed in pairs in correspondence so as to jointly fix the hinge 5 and the device 1 by means of additional fasteners 6c. This allows, according to one embodiment, a robust fixing in a vertical direction of the 2. A retaining system on one leaf. This allows for better grip on the hinge 5 at the strike plate 4, thus providing greater strength in the locked configuration. The additional fixing elements 6c can be secured with screws or rivets.

[0081] According to one example, the additional through-openings 1132 and the additional through-holes 5c are positioned so as to be aligned along a vertical dimension. More precisely, the additional through-openings 1132 and the additional through-holes 5c are positioned so as to be aligned along a direction perpendicular to the principal extension direction Xn4.

[0082] According to one embodiment, the holding device 1 comprises a movable part and a fixed part relative to a leaf 2. The fixed part comprising at least one of the following: the guide relay 115, the protection box 113a and the box 113. The movable part comprising at least: the control portion 11 and the locking portion 112, the transmission member 114.

[0083] According to a particular embodiment, the retaining device 1 is configured so that the beak 112a includes an asperity extending transversely to the main extension direction Xn4 of the transmission member 114 so as to allow a stop in butt of the blocking portion 112 against the protective housing 113a.

[0084] According to one example, the retaining device 1 can be oriented vertically with respect to the ground or at an angle.

[0085] According to an example, an assembly can be provided comprising a leaf 2 and the system detailed in the paragraphs above.

[0086] According to an example, a building opening can be provided comprising a peripheral frame 3 delimiting a passage and the whole.

[0087] Method for fixing the system:

[0088] According to one example, the fixing of the holding system includes a positioning of a hinge 5 on a leaf 2. The hinge 5 extends along the transverse dimension of a leaf 2 and has at least one through hole 5a, 5b.

[0089] Subsequently, an alignment of at least one through opening 1131, 1151 of the retaining device 1 with at least one through hole 5a, 5b of the hinge 5. The retaining device 1 may have its main extension dimension Xn4 parallel to the transverse dimension of a leaf 2.

[0090] Following the alignment step, there may be a fixing of the retaining device 1 and the hinge 5 via the same fixing element 6a, 6b configured so as to fix the device 1 and the hinge 5 together to a leaf 2.

[0091] According to one example, a step of fixing the strike plate 4 onto a frame 3 is carried out after the step of fixing the retaining device 1 and the hinge 5. The strike plate 4 is fixed so that the longitudinal dimension of the strike plate 4 is parallel to the Main extension direction Xn4 of the retaining device 1. The strike plate 4 is thus only in contact with the retaining device 1 and / or with the hinge 5. This allows the strike plate 4 not to be in direct contact with a leaf 2, preventing damage to the latter when switching from an unlocked configuration to a locked configuration.

[0092] According to one example, a step of positioning the strike plate 4 by means of a template 4' (illustrated in [Fig.6A]) is carried out before the step of fixing the strike plate 4.

[0093] According to one example, the template 4' is configured to be positioned in accordance with the blocking portion 112. The template 4' can then have a shape such as to present a raised portion configured to mark a point on a frame 3. The template 4' thus makes it possible to mark the wall to facilitate the positioning of the strike plate 4 and therefore facilitate the installation of the system. More precisely, the raised portion makes it possible to define the point where the adjustment portion 4a of the strike plate 4 can be positioned. Similarly, the raised portion makes it possible to define the point where a strike plate fixing element can be positioned.

[0094] According to one example, the strike plate 4 is fixed using a strike plate fixing element. The strike plate fixing element may be a screw. This eliminates the need for additional tools to install the system.

[0095] The invention is not limited to the embodiments described above and extends to all embodiments covered by the invention. The present invention is not limited to the examples described above. Many other embodiments are possible, for example by combining features described above, without departing from the scope of the invention. Furthermore, the features described with respect to one aspect of the invention can be combined with another aspect of the invention.
