Description

Title of the invention: CLOSING DEVICE FOR OPENING A PREMISES Technical field of the invention

[0001] The present invention relates to a closing device for opening, for example, a room such as an electrical cabinet. Technical background

[0002] Closing devices intended to close openings in premises in which electrical installations are installed usually comprise at least one hinged panel mounted on hinges which allow said panel to pivot in order to open or close access to the interior of the premises.

[0003] Given the electrical installations they house, these premises require secure access in order to protect both the installation and the user who may be nearby.

[0004] Thus, such premises or electrical cabinets are usually installed in confined spaces, for example in the basement of a building where the peripheral clearance zone is reduced.

[0005] Thus, one of the problems with devices for closing premises housing electrical installations and comprising hinged panels according to the prior art concerns their size. In fact, the hinged panels require a large clearance space to be able to pivot in order to provide access to the interior of the premises.

[0006] We then know of closing devices which integrate panels screwed around the perimeter of the opening, but such an installation proves tedious for an operator who must unscrew all the screws to be able to access the interior of the room.

[0007] Closing devices are also known which incorporate sliding panels, but such an installation also requires significant clearance to allow the panels to move in translation.

[0008] Thus, the invention proposes to remedy the aforementioned problem by proposing a device for closing a room, housing an electrical installation, which comprises panels having a small footprint when they allow access to the interior of the room, while being simple and quick to assemble and disassemble.

[0009] The closing device according to the invention also has the advantage of being simple and quick to manufacture, which makes it possible to reduce design costs. Summary of the invention

[0010] The invention provides a closing device intended to at least partially close an opening of a room comprising an electrical installation, the closing device comprising at least one upper lintel and a lower lintel which vertically delimit a receiving space for at least one panel intended to at least partially close the opening, each of the lintels comprising mortises aligned longitudinally with respect to each other, the panel comprising upper tenons and lower tenons which extend vertically projecting respectively from an upper end and a lower end of a main body of the panel, the panel being movable between a position for closing the opening in which the upper tenons and the lower tenons extend at least partially through the mortises respectively of the upper lintel and the lower lintel,and an open position in which the tenons extend outside the mortises of the upper lintel and the lower lintel.

[0011] According to other characteristics of the invention: - the tenons of the panel each comprise a first extension which extends vertically from the main body of the panel and each comprise a second extension which extends vertically from the first extension, the first extension of each of the tenons extending longitudinally over a first length and the second extension of each of the tenons extending longitudinally over a second length strictly less than the first length; - the first extension of each of the tenons comprises stop surfaces which extend longitudinally on either side of the associated second extension of the tenon, the stop surfaces being configured to vertically lock the panel in position between the lintels when it is in its closed position; - the second extensions of each of the panel tenons are configured to extend vertically through the mortises of the upper lintel and the lower lintel when the panel is in its closed position; - the mortises comprise an insertion portion which comprises a first transverse dimension and a locking portion which comprises a second transverse dimension strictly less than the first transverse dimension, the locking portion being configured to receive and transversely lock in position the second extension of the tenons when the panel is in its closed position; - the tenons take the form of flat plates made from the same material as the main body of the panel; - the panel has a transverse thickness which is less than the second transverse dimension of the locking portion of the mortises; - the closing device comprises two panels and a longitudinal holding element which connect the two panels to each other when they are in their closed position and in such a way as to lock them in position in the longitudinal direction.

[0012] The invention also relates to a method of mounting a panel of a closing device according to any one of the preceding characteristics, in its closed position, the mounting method comprising:

[0013] - a first step during which the upper tenons are inserted vertically wedged into the mortises of the upper lintel; and

[0014] - a second step during which the panel is moved vertically from such that the lower tenons fit vertically into the mortises of the lower lintel; and

[0015] - a third step during which the panel is moved in longitudinal translation tudinal such that at least one of the abutment surfaces of the first extensions of the tenons each extends opposite one of the lintels so as to vertically lock the panel in position between the lintels.

[0016] According to another characteristic of the assembly method, in the third step, the second extensions of each of the tenons of the panel are housed in the locking portions of the mortises. Brief description of the figures

[0031] For the description of the invention and the understanding of the claims, the vertical, longitudinal and transverse orientations according to the reference V, L, T indicated in the figures, the longitudinal L and transverse T axes of which extend in a horizontal plane, will be adopted as a non-limiting example and without limiting reference to Earth's gravity.

[0032] In the following description, identical, similar or analogous elements will be designated by the same reference numbers.

[0033] [Fig.l] illustrates a device 10 for closing an opening 12, for example of a room in which an electrical installation is installed, for example for connecting a photovoltaic installation to an electrical supply network.

[0034] The opening 12 then corresponds to access to the interior of the room which includes the electrical installation.

[0035] The opening 12 here has an outline in the shape of a quadrilateral.

[0036] An upper side 12a of the opening 12 and a lower side 12b of the opening 12 are then defined, corresponding to the sides which vertically delimit said opening 12.

[0037] The closing device 10 illustrated in [Fig.l] comprises an upper lintel 14a and a lower lintel 14b which each extend mainly in a longitudinal direction L and opposite each other in a vertical direction V.

[0038] In particular, the upper lintel 14a extends against the upper side 12a of the opening 12 and the lower lintel 14b extends against the lower side 12b of the opening 12.

[0039] Thus, the upper lintel 14a and the lower lintel 14b vertically delimit a space for receiving two panels 16 configured to at least partially close opening 12 when they are in a closed position.

[0040] At least partially closing the opening means that the panels prevent the passage of an individual when they are in their closed position.

[0041] The two panels 16 each extend in a main vertical elongation direction V, between the upper lintel 14a and the lower lintel 14b.

[0042] Thus, the upper lintel 14a and the lower lintel 14b have the function of holding and locking the panels 16 in position through the opening 12 so that said panels 16 close access to the interior of the room when they are in the closed position.

[0043] The technical characteristics allowing cooperation between the upper 14a and lower 14b lintels and the panels 16 will now be described by means of figures 1 to 5b.

[0044] Furthermore, it should be considered that initially, the structural characteristics of each of the elements of the closing device 10 are described separately and then the cooperation between each of the elements of the closing device 10 will be the subject of a detailed description.

[0045] The upper lintel 14a and the lower lintel 14b are structurally identical to each other. Thus, in the remainder of the detailed description, the term lintel 14a, 14b will be used to designate indifferently structural characteristics of the upper lintel 14a or the lower lintel 14b. In particular, the structural characteristics of the upper 14a and lower 14b lintels will be described by means of the lintel 14a, 14b illustrated in [Fig.2].

[0046] The lintel 14a, 14b comprises a central flat portion 18 in the shape of a quadrilateral and from which four borders extend.

[0047] In particular, the edges of the lintel 14a, 14b extend perpendicularly from the central portion 18 of the latter.

[0048] An upper longitudinal edge 20a and a lower longitudinal edge 20b of the lintel 14a, 14b are then defined, opposite each other in the vertical direction V.

[0049] A first vertical edge 20c and a second vertical edge 20d of the lintel 14a, 14b are also defined, opposite each other in the longitudinal direction L.

[0050] It should be considered that the upper and lower terms associated with the longitudinal edges 20a, 20b are defined according to a position of the upper 14a and lower 14b lintels when they are installed in the opening 12 as described previously and considering the Earth's gravity.

[0051] As seen in [Fig.2], the upper longitudinal edge 20a of the lintel 14a, 14b comprises mortises 22.

[0052] More precisely, the upper longitudinal edge 20a of the lintel 14a, 14b comprises a first group 22a of three mortises 22 and a second group 22b of three mortises 22 opposite each other in the longitudinal direction L.

[0053] In the illustrated example of the invention, the mortises 22 of the same group 22a, 22b of mortises 22 extend at longitudinal equidistance from each other.

[0054] Furthermore, all of the mortises of the lintel 14a, 14b extend in the longitudinal direction L.

[0055] One of the mortises 22 of the lintel 14a, 14b is illustrated in [Fig.3].

[0056] Furthermore, the mortises 22 according to the example of the invention are structurally identical to each other. Thus, it should be considered that the structural characteristics described for the mortise 22 of [Fig. 3] apply mutatis mutandis to all the mortises 22 of the lintel 14a, 14b.

[0057] As seen in [Fig.3], the mortise 22 extends longitudinally along a first dimension D1.

[0058] According to a non-limiting example, the first dimension D1 is between 100mm and 150mm, preferably 140mm.

[0059] The mortise 22, visible in [Fig. 3], comprises a portion which comprises a first transverse dimension DTI, called the insertion portion 24, and a portion having a second transverse dimension DT2 strictly less than the first transverse dimension DTI, and called the blocking portion 26.

[0060] According to a non-limiting example of the invention, the first transverse dimension DTI is between 3.5mm and 4.5mm, preferably 4mm and the second transverse dimension DT2 is between 1mm and 2mm, preferably 1.5mm.

[0061] Between the insertion portion 24 and the blocking portion 26 extends an intermediate portion 28, a transverse dimension of which decreases from the first transverse dimension DTI to the second transverse dimension DT2.

[0062] More precisely, the intermediate portion 28 forms a guide ramp from the insertion portion 24 to the blocking portion 26.

[0063] Furthermore, the insertion portion 24 extends along a first longitudinal dimension DL1 and the blocking portion 26 extends along a second longitudinal dimension DL2 strictly less than the first longitudinal dimension DLL.

[0064] According to a non-limiting example of the invention, the second longitudinal dimension DL2 is between 30mm and 50mm, preferably 40mm.

[0065] As seen in [Fig.2], the mortises 22 of the first group 22a extend longitudinally along the upper longitudinal edge 20a of the lintel 14a, 14b such that their locking portions 26 face the second group 22b of mortises 22 and the mortises 22 of the second group 22b extend longitudinally along the upper longitudinal edge 20a such that their blocking portions 26 are turned towards the first group 22a of mortises 22.

[0066] In other words, the first group 22a and the second group 22b of mortises 22 are arranged on the upper longitudinal edge 20a in such a way that they extend in a mirror image relative to each other considering a transverse plane T and vertical plane V of the lintel 14a, 14b.

[0067] It should also be considered that the lower longitudinal edge 20b of the lintel 14a, 14b comprises a first group of mortises and a second group of mortises whose structural characteristics are identical to those which extend over the upper longitudinal edge 20a.

[0068] In other words, the mortises 22 of the upper longitudinal edge 20a and of the lower longitudinal edge 20b extend in a mirror image relative to each other considering a longitudinal plane L and transverse plane T of the lintel 14a, 14b.

[0069] As seen in [Fig.2], the first vertical edge 20c comprises fixing holes 30 for the lintel 14a, 14b to one of the edges of the opening. The second vertical edge 20d also comprises fixing bores, not visible here.

[0070] Also, the central portion 18 of the lintel 14a, 14b comprises several fixing holes 30 making it possible to fix the lintel 14a, 14b in the opening.

[0071] Advantage is thus taken of the lintels 14a, 14b as described previously, that is to say identical to each other and with their upper 14a and lower 14b longitudinal edges identical, in that they can be indifferently positioned in the opening as upper lintel 14a or lower lintel 14b.

[0072] Thus, it is understood that the lintels 14a, 14b as described are advantageous in that they simplify their manufacture by limiting the needs to a single structure which can be positioned indifferently as an upper lintel 14a or a lower lintel 14b.

[0073] Also, the structure of the lintels 14a, 14b allows them to be manufactured for example by laser cutting a sheet metal plate then by folding.

[0074] Thus, it is understood that when the lintel 14a, 14b is positioned as the upper lintel 14a, its lower longitudinal edge 20b is positioned facing the opening in order to cooperate with the panels and when the lintel 14a, 14b is positioned as the lower lintel 14b it has its upper longitudinal edge 20a facing the opening in such a way as to cooperate with said panels.

[0075] In [Fig.4] one of the panels 16 of the closing device 10 is illustrated.

[0076] It should be considered that in the following description only one of the panels 16 of the closing device 10 will be the subject of a detailed description but that the structural characteristics of the panel 16 described in [Fig.4] apply mutatis mutandis to the other panel 16 of the closing device 10 illustrated in [Fig.l].

[0077] In other words, it is understood that the panels 16 of the closing device 10 are structurally identical to each other.

[0078] The panel 16 comprises a main body 32 which has the shape of a quadrilateral and of which an upper end 34 and a lower end 36 are defined, opposite one another in the vertical direction V.

[0079] As illustrated in [Fig.4], tenons 38 extend vertically from each of the lower end 36 and the upper end 34 of the main body 32 of the panel 16.

[0080] Upper tenons 38a are defined which extend from the upper end 34 of the main body 32 of the panel 16 and lower tenons 38b which extend from the lower end 36 of the main body 32 of the panel 16.

[0081] According to the example illustrated, the panel 16 comprises three upper tenons 38a and three lower tenons 38b.

[0082] Here, each of the tenons 38 of the panels 16 is configured to cooperate with one of the mortises 22 of one of the lintels 14a, 14b as described previously.

[0083] More precisely, the upper tenons 38a of the panel 16 cooperate with the mortises 22 of the first group 22a or of the second group 22b of mortises 22 formed on the lower longitudinal edge 20b of the upper lintel 14a and the lower tenons 38b cooperate with the mortises 22 of the same group 22a, 22b of mortises 22, formed on the upper longitudinal edge 20a of the lower lintel 14b.

[0084] It is then understood that the first groups 22a of mortises 22 of the upper lintel 14a and of the lower lintel 14b are configured to cooperate with the same panel 16 and that the second groups 22b of mortises 22 of the upper lintel 14a and of the lower lintel 14b are configured to cooperate with the other same panel 16 of the closing device 10.

[0085] Furthermore, the panels 16 have a transverse thickness which is less than the second transverse dimension DT2 of the blocking portion 26 of the mortises 22.

[0086] According to a non-limiting example, the transverse thickness of the panels 16 is between 0.5 mm and 1.5 mm, preferably 1 mm.

[0087] The upper tenons 38a and the lower tenons 38b of the panel 16 take the form of flat plates which extend in the extension of the main body 32 of the panel 16 in the vertical direction V.

[0088] In particular, the upper tenons 38a and the lower tenons 38b are made of the same material as the main body 32 of the panel 16.

[0089] Each of the tenons 38 of the panel 16 comprises a first extension 40 which extends vertically from the main body 32 of the panel 16 and which is extended vertically by a second extension 42 in the vertical direction V.

[0090] As visible in [Fig.5a], a first upper length LSI of the first extensions 40 of the upper tenons 38a and a second length su are defined. upper LS2 of the second extensions 42 of the upper tenons 38a, considering the longitudinal direction L.

[0091] The first upper length LSI is strictly greater than the second upper length LS2.

[0092] According to a non-limiting example, the first upper length LSI is between 70mm and 110mm and the second upper length LS2 is between 30mm and 50mm, preferably 40mm.

[0093] It is then understood that the second extension 42 of the upper tenons 38a forms a tongue which extends vertically from the first extension 40 of the upper tenons 38a.

[0094] Furthermore, the first extension 40 of the upper tenons 38a has a rectangular shape such that it comprises two flat upper stop surfaces 44a which extend longitudinally on either side of the second extension 42.

[0095] Thus, it is understood that the first extension 40 and the second extension 42 of the upper tenons 38a form a staircase structure of the upper tenons 38a, in a longitudinal plane L and vertical plane V of the panel 16.

[0096] According to the example illustrated, the upper tenon 38a which extends in the center of the two other upper tenons 38a, considering the longitudinal direction L, has its first extension 40 in the shape of a trapezium.

[0097] Such a configuration of the upper tenon 38a comprising its first extension 40 in the shape of a trapezium makes it possible to facilitate the cooperation of the upper tenons 38a with the mortises 22 of the upper lintel 14a by forming a guide surface.

[0098] According to the illustrated example, the first upper length LSI of the first extension 40 of the upper tenons 38a is strictly less than the first dimension DI of the mortises 22, such that the upper tenons 38a of the panel 16 are able to vertically pass through the mortises 22 of one of the groups 22a, 22b of the lower longitudinal edge 20b of the upper lintel 14a, in a mounting position of the panel 16, as illustrated in [Fig.6b].

[0099] According to a preferred example of the invention, the first upper length LSI of the first extension 40 of the upper tenons 38a is substantially identical to the first longitudinal dimension DL1 of the insertion portion 24 of the mortises 22.

[0100] It is understood that thus, in a mounting position of the panel 16 visible in [Fig.6b], the upper tenons 38a are able to vertically pass through the insertion portion 24 of the mortises 22 of the upper lintel 14a.

[0101] Furthermore, the second upper length LS2 of the second extensions 42 of the upper tenons 38a is substantially equal to the second longitudinal dimension DL2 of the locking portions 26 of the mortises 22, such that they are capable of being housed in said locking portions 26 in the closed position of the panels. 16 as seen in [Fig.8b].

[0102] As visible in [Fig.5b], a first lower length LU of the first extensions 40 of the lower tenons 38b and a second lower length LI2 of the second extensions 42 of the lower tenons 38b are defined, considering the longitudinal direction L.

[0103] The first lower length LU is strictly greater than the second lower length LI2.

[0104] It is then understood that the second extension 42 of the lower tenons 38b forms a tongue which extends vertically from the first extension 40 of the lower tenons 38b.

[0105] Furthermore, the first extension 40 of the lower tenons 38b has a rectangular shape such that it comprises two flat lower stop surfaces 44b which extend longitudinally on either side of the second extension 42.

[0106] Thus, the first extension 40 and the second extension 42 of the lower tenons 38b form a staircase structure of the lower tenons 38b, in a longitudinal plane L and vertical plane V of the panel 16.

[0107] According to the example illustrated, the first lower length LU of the first extension 40 of the lower tenons 38b is strictly greater than the first dimension DI of the mortises 22.

[0108] Furthermore, the second lower length LI2 of the second extension 42 of the lower tenons 38b is strictly less than the first dimension DI of the mortises 22.

[0109] It is thus understood that only the second extensions 42 of the lower tenons 38b are capable of passing through the mortises 22 of the lower lintel 14b during the assembly of the panel 16 as visible in [Fig.7b].

[0110] Thus and as visible in [Fig.7b], the lower stop surfaces 44b are in contact with the upper longitudinal edge 20a of the lower lintel 14b when the second extensions 42 of the lower tenons 38b pass through the mortises 22 of said lower lintel 14b, in the panel mounting position.

[0111] Furthermore, the second lower length LI2 of the second extensions 40 of the lower tenons 38b is substantially equal to the second longitudinal dimension DL2 of the locking portions 26 of the mortises 22, such that they are able to be housed in said locking portions 26 in the closed position of the panels 16 as visible in [Fig.8c].

[0112] As partially visible in Figures 6b and 7b, the panel 16 comprises vertical edges 46 which extend in a plane intersecting a plane of the main body 32 of the panel 16.

[0113] The vertical edges 46 folded relative to the main body 32 of the panel 16 make it possible, among other things, to reinforce the rigidity of the panel 16.

[0114] Also, the vertical edges 46 folded relative to the main body 32 of the panel 16 allow the panels 16 to be easily stacked on top of each other when stored.

[0115] The panel 16 as described can be manufactured by laser cutting a piece of sheet metal and then by folding.

[0116] A method of mounting the closure device 10 will now be described in relation to FIGS. 1 to 8c.

[0117] It should be considered that prior to the method of mounting the closing device, it is considered that the panels 16 are in an open position, that is to say that they are completely detached from the lintels 14a, 14b. In other words, in the open position of the panels 16, these are spatially at a distance from the lintels 14a, 14b and their tenons 38a, 38b are not engaged in the mortises 22.

[0118] For example, in the case of an opening of a room comprising an electrical installation, the panels are arranged against a wall next to the room, and thus outside the opening so as to clear the opening of the room for an operator.

[0119] As seen in Figures 6a and 6b, at a first stage of the assembly of the closing device 10 the upper tenons 38a of the panel 16 are inserted vertically into the mortises 22 of the first group 22a formed on the lower longitudinal edge 20b of the upper lintel 14a.

[0120] More precisely, the first step consists of the vertical insertion of the first extension 40 and the second extension 42 of the upper tenons 38a through the insertion portion of the mortises 22 of the first group 22a formed on the lower longitudinal edge 20b of the upper lintel 14a as visible in [Fig.6b],

[0121] It is then understood that at the end of this insertion, the upper end 34 of the main body 32 of the panel 16 is in contact with the lower longitudinal edge 20b of the upper lintel 14a.

[0122] It is also understood that to carry out this insertion of the upper tenons 38a, the panel 16 is slightly inclined relative to a vertical plane V and longitudinal plane L, so as to be installed in the reception space delimited by the lintels 14a, 14b.

[0123] At the end of the first step, the panel 16 extends in a vertical plane V and longitudinal plane L, between the lintels 14a, 14b.

[0124] More precisely, at the end of this first step, the lower tenons 38b extend at a non-zero vertical distance from the lower lintel 14b, as visible in [Fig.6a].

[0125] Thus, it is understood that the panels 16 extend over a first dimension vertical DV1 strictly less than a second vertical dimension DV2 of the reception space delimited by the lintels 14a, 14b, the first vertical dimension DV1 of the panel 16 being taken vertically between the upper end 34 of the main body 32 of the panels 16 and a vertical free end of the second extensions 42 of the lower tenons 38b.

[0126] It is understood according to the illustrated example that the second vertical dimension DV2 extends vertically between the lower longitudinal edge of the upper lintel 14a and the upper longitudinal edge of the lower lintel 14b.

[0127] Once the first step has been carried out, in a second step visible in [Fig.7a], the panel 16 is moved vertically towards the lower lintel 14b so that the second extensions 42 of the lower tenons 38b, visible in [Fig.7b], vertically pass through the mortises 22 of the first group 22a formed on the upper longitudinal edge 20a of the lower lintel 14b.

[0128] During this second step, the lower abutment surfaces 44b of the first extensions 40 of the lower tenons 38b rest against the upper longitudinal edge 20a of the lower lintel 14b and the second extensions 42 of the lower tenons 38b pass through the insertion portion of the mortises 22, as visible in [Fig.7b],

[0129] Furthermore, such insertion of the second extensions 42 of the lower tenons 38b into the mortises 22 vertically moves the panel 16 such that only the second extensions of the upper tenons 38a extend through the insertion portion of each of the mortises of the first group formed on the lower longitudinal edge of the upper lintel 14a.

[0130] In other words, at the end of the second step, the first extensions of the upper tenons 38a extend outside the mortises of the first group formed on the lower longitudinal edge of the upper lintel 14a, as visible in [Fig.8a].

[0131] It is then understood that a third vertical dimension DV3 of the panel 16, visible in [Fig.7a], taken vertically between the upper stop surfaces 44a and the lower stop surfaces 44b is substantially identical to the second vertical dimension DV2 of the reception space delimited by the lintels 14a, 14b.

[0132] It is also understood that the second extensions 42 of each of the tenons 38 extend over a fourth vertical dimension DV4, visible in FIGS. 5a and 5b, sufficient for said second extensions 42 of the tenons 38 to be engaged vertically through the mortises 22 of the lintels 14a, 14b at the end of the second step.

[0133] In other words, the fourth vertical dimension DV4 of the second extensions 42 is configured to ensure that the tenons 38 are held in the mortises 22 at the end of the second step.

[0134] According to a non-limiting example, the fourth vertical dimension DV4 is between 10mm and 30mm.

[0135] Furthermore, the second extensions 42 of the upper tenons 38a may comprise a fourth vertical dimension DV4 different from the fourth vertical dimension DV4 of the second extensions 42 of the lower tenons 38b.

[0136] Following this second step, a third step of the assembly method visible in Figures 8a to 8c is implemented, in which the panel 16 is moved in translation along the longitudinal direction L.

[0137] In other words, during the third step the panel 16 is moved longitudinally so that the second extensions 42 of the upper 38a and lower 38b tenons are housed respectively in the locking portions 26 of the mortises 22 of the first group 22a formed on the lower longitudinal edge 20b of the upper lintel 14a and of the first group 22a formed on the upper longitudinal edge 20a of the lower lintel 14b, as seen respectively in [Fig.8b] and 8c.

[0138] At the end of this third step, one of the upper abutment surfaces 44a, visible in [Fig.5a], of each of the upper tenons 38a is opposite the lower longitudinal edge 20b of the upper lintel 14a and one of the lower abutment surfaces 44b, visible in [Fig.5b], of each of the lower tenons 38b is in abutment against the upper longitudinal edge 20a of the lower lintel 14b, as illustrated respectively in Figures 8b, 8c.

[0139] It is then understood that at the end of the third step, the panel 16 is blocked vertically in position between the upper lintel 14a and the lower lintel 14b, the panel 16 being in its position for closing the opening 12.

[0140] Furthermore, the locking in position of the second extensions 42 of the upper 38a and lower 38b tenons in the locking portions 26 of the mortises 22 makes it possible to lock the panel 16 in position in the transverse direction.

[0141] Such an engagement of the second extensions 42 of the upper 38a and lower 38b tenons in the locking portions 26 of the mortises 22 makes it possible to limit the vibrations of the panel 16 when it is in its position of closing the opening 12.

[0142] The same steps of the assembly method as described above apply to the other panel of the closure device 10.

[0143] Advantage is also taken of the panels 16 being structurally identical to each other in that they can be installed interchangeably between the lintels. In other words, no particular position of the panels relative to each other is required to install them between the lintels.

[0144] Thus, the assembly of the panels between the lintels is made easier for the operator and the manufacturing costs of said panels are also reduced.

[0145] Once the two panels 16 of the closing device 10 are installed in their closed position of the opening 12, a longitudinal holding element 48, visible in [Fig.l], can be installed between the two panels 16 so as to secure them to each other and thus, lock them in position in the longitudinal direction L.

[0146] The longitudinal holding element 48 then prevents the panels 16 from moving longitudinally and thus blocks the second extensions of the tenons in the locking portions of the mortises, as described above.

[0147] As seen in Figures 1 and 4, the main body 32 of the panel 16 includes gripping holes 50 making it easier for a user to handle the panels 16 during the assembly method described above.

[0148] It is further understood that to dismantle the panels 16 from the lintels 14a, 14b the steps of the assembly method are carried out in reverse, that is to say from the third step to the first step.

[0149] Thus, the panels are detached from the lintels 14a, 14b by simple longitudinal and vertical movements and can subsequently be stored outside the opening in order to allow the user to pass through the opening of the room.

[0150] It is then understood that the panels 16 of the closing device 10, once removed from the lintels 14a, 14b, have a reduced size leaving more space for the operator who must, for example, carry out maintenance on the electrical or photovoltaic installation.
