Description

INTERIOR DOOR OF A HOUSING INCLUDING AN ELASTIC CLOSING SYSTEM

GENERAL TECHNICAL AREA AND PRIOR ART

The present invention relates to an interior door of a housing.

Conventionally, an accommodation comprises walls separating different rooms. As illustrated in FIG. 1, an interior door 100 is mounted in a wall M in order to allow the passage from one room to another. The interior door 100 comprises a frame 110, which is a fixed part mounted in the wall M, and an opening 120 which is a movable part articulated on the frame 110.

The frame 110 is in the form of a frame comprising a left vertical upright 111 and a right vertical upright 112 connected at their upper ends by a horizontal upright 113. The frame 110 defines, in the wall M, a passage opening between the two parts separated by the wall M. In a known manner, the opening 120 is in the form of a rectangle defining a left vertical edge and a right vertical edge as well as an upper horizontal edge and a lower horizontal edge. With reference to FIG. 1, the door 100 comprises hinges 130 connecting the left vertical edge of the opening 120 to the left vertical upright 111 of the frame 110 in order to allow the opening of the opening 120.

In this example, the door 100 further comprises a handle 140 mounted on the opening 120 and allowing a user to pivot the opening 120 between the open position and the closed position by pulling or pushing the handle 140. Still in with reference to FIG. 1, the door 100 also comprises a closing system 150 associated with the handle 140, mounted at the level of the right vertical edge, making it possible to lock the door 100 in the closed position.

As illustrated in FIGS. 2 and 3, the closure system 150 comprises a sash part 150A mounted on the sash 120 and a frame part 150B mounted on the sash 110 which cooperate together. With reference to FIG. 3, the frame part 150B comprises a keeper 151 comprising a cavity C. With reference to FIG. 2, the opening part 150A comprises a bolt 152 which can be moved in order to extend projecting from the right vertical edge of the opening 120 in order to be housed in the cavity C and thus block the rotation of the opening 120 in order to lock the door 100 in the closed position. The bolt 152 is actuated by a nut 153 which is rotated by the handle 140. Thus, when a user wishes to open the door 100, the latter grasps the handle 140, rotates it in order to unlock the bolt 152 and then pulls or pushes door 100 so as to open it.

In known manner, the bolt 152 and the nut 153 are mounted in a machining carried out in the opening 120 and the keeper 151 is mounted in a machining carried out in the frame 110. Also, to mount such a closing system 150, it is necessary to practice machining in the two parts of the door 100 in order to accommodate the various elements. This therefore requires numerous manufacturing and assembly operations, which is complex and increases the costs of manufacturing such a door 100.

In addition, such a door 100 includes many elements which are expensive and the movable elements, such as the handle 140, the bolt 152 and the nut 153, wear out, requiring an adjustment of their position, see their replacement, which further increases costs.

Finally, from a safety point of view, in the event of the handle 140 breaking, it is very complex to open the door 100, which can be anxiety-provoking when a person, in particular a child, is blocked alone in a room. housing.

There is therefore a need for a system for closing an interior door allowing a user to open and close the interior door efficiently and inexpensively.

GENERAL PRESENTATION OF THE INVENTION

To this end, the invention relates to an interior door of a housing, said door comprising a frame mounted in a wall of the housing and defining a passage opening through said wall, and an opening mounted movable relative to said frame, said door comprising means of articulation of said opening relative to said frame between an open position and a closed position, and a passive closure system adapted to lock the door in the closed position, said closure system comprising at least one groove formed in the frame and at least one elastic element mounted on the opening, the elastic element being adapted to cooperate with the groove so as to block the position of the opening relative to the frame in the closed position.

Thanks to the door according to the invention, it is possible to keep the door in the closed position thanks to the mechanical cooperation of elements mounted on the door and on the frame. Such a closing system makes it possible to open the door even when the handle is broken, which prevents a person from being trapped inside a room. In addition, such a closure system limits the number of movable elements required, which limits wear and therefore maintenance costs. The number of machining steps is reduced or eliminated.

The cooperation of an elastic element and a groove makes it possible to form a sound barrier, which improves general performance at a reduced cost. Such cooperation also has "fire-fighting" advantages by prohibiting, at least partially, the circulation of air.

Advantageously, the groove extending longitudinally, its cross section has a concave V shape in order to make it easy to move the elastic element out of the groove during the tilting of the door in the open position. A first slope of the V allows guiding while the other slope allows to form a stop in order to self-center the opening in the closed position. A concave shape makes it possible to define a stable position which remains effective, even in the event of wear of the elastic element.

Preferably, the elastic element extending longitudinally, its cross section has a convex V shape in order to make it easy to move the elastic element out and into the groove during the tilting of the door. A cooperation by complementarity of forms allows for a hermetic closure. A beveled shape also helps limit wear.

According to a preferred aspect, the elastic element comprises metallic mouse in order to allow optimal maintenance of the elastic element in the groove in the closed position.

Advantageously, the frame comprising two vertical uprights connected at their upper end by a horizontal upright, said uprights defining said passage opening, the articulation means being connected to one of said vertical uprights, the groove extends over the other of said uprights vertical to optimize the maintenance of the door in closed position.

In one aspect, the frame has a groove extending into the horizontal upright to provide a more airtight closure.

Advantageously, the groove extends over at least 60% of the length of said vertical upright in order to allow the closing system to have sufficient strength to keep the door in the closed position.

Preferably, the vertical upright comprises a compression surface, extending parallel to the groove, configured to gradually compress the elastic element when the door is closed.

Advantageously, the door comprises a system for locking the door in the closed position, said locking system and the closing system being distinct. Thanks to the locking system separate from the closure system, it is possible to replace them separately during a maintenance operation, which limits their costs. Preferably, the locking system comprises a latch movably mounted in rotation between a locking position and an unlocking position in order to limit the size of such a locking system.

Preferably, the door comprises means for gripping the opening allowing a user to switch the door between the open position and the closed position, the gripping means being separate from the closing system. Thanks to the gripping means separate from the closing system, it is possible to open and close Ια door even when the gripping means are broken by pushing the door.

According to a preferred aspect, said closure system consists of one or more grooves formed in the frame and one or more elastic elements mounted on the opening. The design of the locking system is reduced to a few components, which facilitates its maintenance and limits its manufacturing cost.

According to one embodiment, the door further comprises a bracket fixed to the frame in order to form a stop for the movement of the opening element in the closed position. Preferably, the frame comprising two vertical uprights connected at their upper end by a horizontal upright, said uprights defining said passage opening, the articulation means being connected to one of said vertical uprights, the bracket is fixed to the other of said vertical uprights, more preferably at the upper end of said vertical upright.

Preferably, the frame extends in the same plane as the opening. In other words, the frame does not include a rebate and does not extend projecting from the opening. We benefit from high aesthetic properties without losing the stop function.

DESCRIPTION OF ONE OR MORE MODES OF IMPLEMENTATION AND IMPLEMENTATION

Referring to Figure 4, there is shown schematically a wall M of a residential building, also designated "housing". Such housing is a construction comprising an interior space divided by walls M in order to delimit different parts of the housing. The interior space includes a floor extending substantially horizontally, the walls M extending substantially vertically from the floor. We thus define an XYZ coordinate system in which the X and Y axes extend horizontally and in which the Z axis extends vertically. In the example illustrated in Figure 4, the wall M extends in a vertical plane XZ.

To go from one room to another, a door 1 is mounted in the wall M as illustrated in FIG. 4. In a known manner, the interior door 1 comprises a frame 10 which is a fixed part mounted in the wall M, and an opening 20 which is a movable part articulated on the frame 10. The opening 20 is mounted so as to be able to rotate relative to the frame 10 between a closed position and an open position. The user pushes or pulls the door 20 so as to switch the door 20 between the closed position and the open position. The wall M separates an area called "interior I", in which the opening 20 extends in the open position, and an area called "exterior E". In other words, the opening 20 opens inwards I.

The frame 10 comprises a left vertical upright 11 and a right vertical upright 12 connected at their upper ends by a horizontal upright 13, extending along the axis X, in order to form a frame in the shape of an inverted U. Such a frame defines, in the wall M, an opening O for passage between the two parts separated by the wall M. The frame 10 comprises an inner face 101 facing inward I and an outer face 10E facing outward E as illustrated in FIGS. 5 and 6. The inner face 101 extends over the horizontal upright 13 and over the vertical uprights 11, 12. The opening 20 is articulated on the frame 10 between an open position in which access to the opening O for passage is free and a closed position in which the opening 20 extends through the opening O for passage so as to block access to it. The frame 10 further comprises an internal face 10L oriented towards the opening 20. This internal face 10L extends over the left vertical upright 11, over the right vertical upright 12 as well as over the horizontal upright 13.

In this embodiment, the opening 20 is in the form of a rectangle defining a left vertical edge 21 and a right vertical edge 22 as well as an upper horizontal edge 23 and a lower horizontal edge 24 as illustrated in the figure. 4.

Similarly, the opening 20 also has an inner face 201 facing inward I and an outer face 20E facing outward E. In the closed position, the outer face 20E is placed facing the inner face 101 of the frame 10. In other words, the inner face 101 of the frame 10 forms a stop for the movement of the opening 20. Thus, the opening 20 can only be moved in one direction, inward I. It goes without saying that the opening 20 and forming 10 could be in other forms.

In known manner, still with reference to FIG. 4, the door 1 comprises articulation means 30 allowing the opening of the door 20 relative to the frame 10 along a vertical axis. In this embodiment, the articulation means 30 comprise a plurality of hinges connecting the left vertical edge 21 of the opening to the left vertical upright 11 of the frame 10. The hinges are offset along the left vertical edge 21 and the upright vertical left 11 along the vertical axis Z.

As illustrated in FIG. 4, the door 1 comprises gripping means mounted on the opening 20 and allowing a user to pivot the opening 20 between the open position and the closed position by pulling or pushing the gripping means .

In this example, the gripping means comprise a handle 40 mounted on each face 201, 20E of the upright 20 in order to allow opening / closing both from inside I and from outside E, as illustrated in FIGS. 5 and 6 It is illustrated in FIGS. 5 and 6 of the pull handles 40. However, in an alternative form, the handles 40 are bowl-type handles. In other words, they are integrated into the thickness of the opening 20. A handle 40 of the bowl type is in the form of a cavity formed in one face 201, 20E of the opening 20, which, in addition to its qualities aesthetic, increases its mechanical resistance and limits any risk of breakage. It goes without saying that other forms of handles 40 could be suitable, in particular, an added handle on one face 201, 20E of the frame 20.

According to the invention, the door 1 also comprises a passive closure system 50 comprising, on the one hand, a groove 51 formed in the frame 10 and, on the other hand, an elastic element 52 mounted on the opening 20. The groove 51 and elastic element 52 are adapted to cooperate together so as to block the position of the door 20 relative to the frame 10 in the closed position. Such a closing system 50 makes it possible to maintain, or block, the door 1 in the closed position. Advantageously, the closure system 50 according to the invention is independent of the gripping means. This increases the resistance of the closing system 50 and thus increases the life of the door 1.

According to the invention, the closure system 50 is a passive closure system. In other words, the locking system 50 does not require any external source of energy, in particular, electricity. Such a passive closure system 50 thus has a reduced cost price.

As illustrated in FIG. 7, the elastic element 52 extends from an edge 22 of the opening 20 and outwards, in other words, towards an upright 12 of the frame 10. Such an elastic element 52 has a first part fixing on the opening 20 and a second elastic part adapted to cooperate with the groove 51 as illustrated in FIG. 7 showing a sectional view of the elastic element 52. In other words, the elastic element 52 has a profile s' extending longitudinally. The first fixing part is formed at a first end of the profile and the second elastic part is formed at a second end of the profile, opposite the first end. The first fixing part has a shape suitable for being mechanically mounted by fitting into a cavity of the opening 20. The first fixing part can also be glued to the opening 20 in order to optimize the fixing between the elastic element 52 and the opening 20.

The second elastic part has a convex V shape and comprises at least a first surface and a second surface which are inclined forming said V shape. In other words, the elastic element 52 is bevelled. With reference to FIG. 7, the first inclined surface is oriented towards the outside E (in the closed position) and forms a first angle a 1 with the edge 22 of the leaf 20. The first angle a 1 is preferably greater than 90 °, preferably still greater than 120 ° in order to facilitate the insertion of the elastic element 52 into the groove 51. Similarly, the second inclined surface is oriented inwards I (in the closed position) and forms a second angle a2 with the edge 22 of the opening 20. The second angle a2 is preferably greater than 90 °, more preferably still greater than 120 ° in order to facilitate the extraction of the elastic element 52 from the groove 51.

The elastic element 52 is made of an elastic material, preferably an elastomer, in order to allow a deformation of the second elastic part when the elastic element 52 moves in or out of the groove 51. The elastic element 52 comprises , preferably, metallic foam, in order to have a sufficiently high hardness in order to maintain the elastic element 52 in the groove 51 in the closed position. The first and second inclined surfaces form a converging end at the level of the second elastic part, which makes it possible to make such a deformation easy by limiting the thickness of the elastic element 52 to be deformed. Preferably, with reference to FIG. 7, the bevel angle a3 is between 20 ° and 70 °.

Referring to Figure 7, the elastic element 52 is centered on the axis of symmetry SS of the opening 20. In other words, the elastic element 52 cooperates with a clearance in the groove 31, of the order of a millimeter .

Referring to Figure 8, the groove 51 extends from the inner face 10L of the frame

10. As illustrated in FIG. 5, the groove 51 can be formed at the level of the upper horizontal upright 13 of the frame 10. Alternatively or optionally, the groove can be formed at the level of the right vertical upright 12 of the frame 10, it that is, on the side opposite the hinges 30.

The groove 51 has a concave V shape and includes at least first and second inclined surfaces forming said V shape. The concave V shape of the groove 51 is adapted to cooperate with the convex V shape of the elastic element. 52 in order to block the position of the elastic element 52 relative to the groove 51. The first inclined surface is oriented inward I and forms a first angle βΐ with the internal face 10L of the frame 10. The first angle βΐ is , preferably, greater than 90 °, more preferably still greater than 120 ° in order to facilitate the insertion and the extraction of the elastic element 52 in the groove 51. The second inclined surface is oriented towards the outside E and forms a second angle β2 with the internal face 10L. The second angle β2 is preferably greater than 90 °, more preferably greater than 120 ° so that the shape of the groove 51 corresponds to the shape of the elastic element 52. This thus allows the elastic element 52 to present a limited clearance in the groove 51 and thus limit any movement clearance of the opening 20 relative to the frame 10 in the closed position. Such a reduced clearance also allows the closure system 50 to exhibit sound insulation characteristics. In other words, the closure system 50 also fulfills the functions of a sound seal. Cooperation by complementary shapes also allows self-centering in the closed position. Preferably, the cavity has an internal angle β3 of between 20 ° and 70 °.

In order to facilitate the insertion of the elastic element 52 into the groove 51, the internal face 10L has an inclined portion 14 illustrated in FIG. 8 adjacent to the groove 51 and positioned on the side of the opening, here inwards I. The inclined portion 14 forms a fourth angle β4 with the internal face 10L of the frame 10. The fourth angle β4 is preferably greater than 10 °, more preferably still greater than 30 ° in order to facilitate the insertion of the elastic element 52 in the groove 51. In fact, during the tilting of the door from the open position to the closed position, the elastic element 52 first of all comes into contact with the inclined portion 14 of the frame 10. Due to the inclination of such an inclined portion, the elastic element 52 gradually deforms, which makes such displacement easy by a progressive force of a user on the opening 20. Then the elastic element 52 enters in contact with the first inclined surface of the groove 51 and gradually returns to its initial shape. In other words, the inclined portion forms a progressive compression surface which extends parallel to the groove 51.

The elastic element 52 is mounted on the opening 20 facing the groove 51 so as to cooperate mechanically in order to lock the opening 20 in the closed position. In the closed position, the elastic element 52 extends in the groove 51. Thus, to open the door 1 according to the invention, a user grasps a handle 40 and pulls or pushes it so as to move the elastic element 52 out of the throat 51.

Preferably, the groove 51 extends over at least 60% of the length of a vertical upright 1 of the frame 10, preferably at least 80%. In one aspect, the groove 51 is only formed on the right vertical upright 12. In a preferred aspect, the groove 51 is only formed on the right vertical upright 12 and the upper horizontal upright 13. Similarly, the elastic element 52 extends over at least 60% of the length of the edges 21, 22 of the opening 20, preferably at least 80%.

The dimensions of the elastic element 52 and of the groove 51 as well as the material of the elastic element 52 are selected so as to have sufficient strength to allow the door 1 to be kept in the closed position while having sufficient strength to allow to a user to easily open the door 1 by pushing or pulling a handle 40.

Such a passive closure system 50 advantageously makes it possible to open and / or close the door 1 when the handle 40 is broken. Indeed, the user can simply push on the inner face 201 of the door 1 to switch it to the closed position or on the outer face 20E to switch the door 1 to the open position. In addition, the inclined surfaces of the groove 51 and of the elastic element 52 allow the door 20 to be perfectly aligned with the frame 10 even if the user has not placed the door 20 completely against the frame. 10. In other words, self-centering is carried out automatically.

Referring to Figures 9 to 10, the door 1 optionally includes a locking system 60 for locking the door 1 in the closed position.

The locking system 60 is also separate from the gripping means and from the closing system 50. This makes it possible to limit maintenance operations in the event of one of these elements breaking by only changing the defective element.

As illustrated in FIGS. 9 and 10, the locking system 60 comprises a latch 61 secured to a pin 62 hingedly mounted in the opening 20.

Preferably, the opening 20 comprises a cavity 25 in which the axis 2 is mounted and in which the latch 61 is retracted in the unlocked position as illustrated in FIGS. 10 and 11. Such a locking system 60 is thus integrated in the opening 20, which limits its size. The axis 62 extends horizontally and orthogonally to the faces 201, 20E of the opening 20. To actuate the locking system 60, the user grasps one end of the axis 62 to drive the rotation of the latch 61. The axis 62 extends projecting from the interior face 201 and from the exterior face 20E so as to allow a user to actuate the locking system 60 from the interior I as well as from the exterior E.

As illustrated in FIG. 9, the latch 61 switches to the locked position by rotation of the rod 62 around its axis. In the locked position, the latch 61 extends horizontally and projects from the right vertical edge 22 of the opening 20 so as to extend inside a cavity 15 included in the right vertical upright 12 of the frame 10 In the locking position, the latch 61 thus blocks the rotation of the opening 20 relative to the frame 10 in order to lock the door 1 in the closed position. As illustrated in FIG. 10, in the unlocking position, the latch 61 extends vertically and inside the cavity 25 of the opening 20. Thus, in the unlocking position, the latch 61 does not block the rotation of the opening 20 relative to the frame 10, which allows the opening of the door 1.

Thanks to the invention, an internal housing door can be obtained which can be closed and locked reliably and securely at low cost.

According to a second embodiment of a door 1 according to the invention illustrated in FIG. 11, the frame 10 forms a frame without rebate. In other words, the inner face 101 does not extend over the left vertical upright 11, the right vertical upright 12 and the horizontal upright 13. In order to form a stop for the opening leaf 20 in the closed position, the frame 10 comprises a bracket 16 fixed on the right vertical upright 12 comprising the internal face 101 on the outside side E. Alternatively, the bracket 16 could also be mounted on the horizontal upright 13, in particular at its right end.

A first part of the bracket 16 is fixed to the internal face 10L, in particular by screwing. A second part of the bracket 16, extending substantially orthogonally to the first part, extends in the passage opening O on the outer side E from the right vertical upright 12. The second part of the bracket 16 comprises the inner face 101 in order to form a stop for the movement of the opening 20.

Such a bracket 16 is advantageously mounted at the upper end of the right vertical upright 12, it therefore does not extend over the entire length of the right vertical upright 12, in order to present a limited bulk and thus reduce its aesthetic impact . Preferably, the bracket 16 extends over a length of the order of 80 mm over the length of the right vertical upright 12. The bracket 16 extends into the opening O over a length of the order of 20 mm with a thickness of 1 mm. According to one aspect of the invention, the bracket 16 is made of a metallic material so as to have sufficient mechanical strength to block the movement of the opening 20 in the closed position.

Such a high position of the bracket 16 also makes it possible to avoid the bracket 16 of 5 forming an obstacle during the passage of a user through the passage opening O of the door 1.

Such a door 1, the frame 10 of which does not include a rebate, thus extends substantially parallel to the wall M and not projecting towards the outside E, or at least 10, than a door 1, the frame of which 10 includes a rebate. Door 1 is thus embedded in the wall M and is barely visible, which improves its aesthetic appearance.

In order to reinforce this embedding, the handles may be in the form of a bowl-type handle 40 ′ as illustrated in FIG. 11. Such a handle 15 40 ′ is thus integrated in the volume of the opening element 20. The door 1 thus does not induce a discontinuity in the wall M.
