ANGULAR ASSEMBLY DEVICE FOR CONSTRUCTING A HOUSING CASE OR A HOUSING, AS WELL AS THE HOUSING HOUSING OR HOUSING
TECHNICAL AREA
The present invention relates to an angular assembly device for constructing a housing frame or a housing, in particular for telecommunications installations, distribution installations, electrical cabinets, control cabinets or cabinets intended to receive computer components. or the like, as well as a housing frame or a housing having an angular assembly device of this type.

 As a general rule, boxes or case frames of this type, which consist of a plurality of angular assembly devices, are used to receive and order electrical, electronic, optical and other active or passive components. The housing or the housing frame can be implemented to be installed both indoors and outdoors. These boxes and box frames are preferably mounted inside to serve as a support structure for housing the various components.

 The cabinet or the external box generally has a cabinet frame made up of vertical and horizontal profiles on which are attached side and rear walls as well as doors.

 To this end, the profiles must be suitably connected to form the cabinet frame. These cabinet frames must be assembled

<Desc / Clms Page number 2>

 at the factory or at the customer. In this regard, it is preferable to use removable assemblies and that the assembly time of the frames is as short as possible to limit the costs of manufacturing the cabinet.

Context
On the one hand, cabinet frames or housings of this type are manufactured from profiles held together by means of suitable templates then assembled by welding at the angles. Welded frames, however, have connections that are removable only under certain conditions. However, the dismantling of the assemblies is an essential requirement on the part of the user.

 On the other hand, some cabinet frames are designed from profiles assembled by screwing to establish a stable connection between the different profiles.

 However, depending on the solution chosen, a plurality of additional elements are required, such as screws and other connecting elements, so that the time necessary to establish a reliable connection between the different profiles is long. Hence the high manufacturing costs of the cabinets.

<Desc / Clms Page number 3>

 The document EP 0 773 615 A1 relates to an electrical cabinet for electrical installations, which comprises a housing comprising a frame made of hollow profiles. At the angles of the hollow profiles are provided angular assembly elements which are inserted into the ends of the rails and uprights formed by said hollow profiles.

 In addition, document DE 41 42 953 relates to an angular assembly segment between two hollow sections connected to each other at a right angle, in particular for table bases. In the front end of the first hollow profile is inserted a connecting element having an axis which is plugged into an opening that has the second hollow profile. The connection between the hollow profiles is then ensured by inserting a key in an opening formed in the axis.

STATEMENT OF THE INVENTION
The present invention sets itself the object of designing an angular assembly device for constructing a housing frame or a housing, which allows angular assembly of profiles with a minimum number of elements and requires little time to perform said angular assembly.

 This technical problem is solved by an angular assembly device having the characteristics of claim 1. The angular assembly device for a cabinet has for this purpose, at an angular assembly, a first profile provided with at least one opening on at least one of its longitudinal faces, a second

<Desc / Clms Page number 4>

 profile provided with at least one recess formed in the same thickness of the second profile and a fixing device provided for securing the first profile with the second, the fixing device being inserted at least in the recess of the second profile to connect the first profile to the second profile by forming the angular assembly.

 The angular assembly device according to the invention for constructing a housing frame or a housing, in particular for telecommunication installations, distribution installations, electrical cabinets or control cabinets in the computer field, comprises a first profile provided, on at least one longitudinal face at an angular assembly, with at least one opening which is formed in at least one end portion of the first profile and which extends from an external face of the first profile up to an internal face of the first profile, a second profile provided with at least one recess formed in the same thickness of the second profile and formed in at least one end region of the second profile and a fixing device for fixing the second profile to the first profile. According to the invention, the second profile can, at its recess, be engaged in the opening so that the second profile can be pressed against the external face of the first profile to form the angular assembly, the device fixing which can be inserted at least in one of the recesses of the second profile, so that the first profile is fixed to the second profile by engaging the fixing device with the recess and the internal face.

<Desc / Clms Page number 5>

 Another object of the present invention is to provide a housing frame or a housing which can be manufactured simply and inexpensively. This objective is solved by a housing frame or a housing having the characteristics of claim 31. The housing frame or housing, which is used in particular in telecommunications installations, distribution installations, electrical cabinets and cabinets control in the IT field, presents, for this purpose at least one angular assembly device according to at least one of claims 1 to 30.

 The idea underlying the invention consists in providing an angular assembly of profiles in which a fixing device is provided to cooperate with a recess formed in a second profile, the first and the second profiles being secured one with the 'other by inserting the fixing device into the recess to form the angular assembly. An angular assembly is thus obtained formed only of the two profiles and of another device, preferably consisting of an element or several elements cooperating advantageously, to secure the two profiles. This measure limits the cost of mounting housing frames or housings formed of angular assembly devices of this type, the connection of the various elements or profiles can in particular be ensured in a simple and effective manner by means of the fixing device, for example a clamping sleeve or a pin, which is force fitted into the recess. The time for producing the angular assembly by connection of the first profile and the second profile is therefore

<Desc / Clms Page number 6>

 limited, so that the angular connection can be manufactured at low cost.

 It is however also possible to fix several second sections each on one face of the first section to form the angular assembly.

It is thus possible to produce a cabinet frame or a cabinet of free shape and dimensions from a plurality of angular assemblies according to the invention in the manner of a construction kit. To do this, it is possible to connect together, as required, standardized profiles of different lengths so as to produce, as desired, a cabinet or a housing frame or a housing made of profiles with any degrees of freedom in terms of dimensions. and form.

 In the context of the invention, the term “profile” means an oblong or drawn element made of a stable material and having any external contour. The profiles can be hollow or solid, all the intermediate steps also being possible. The material used can be a plastic material or a metal. A profile of this type has at least one end accessible from the outside.

 Similarly, in the context of the invention, the term “terminal portion” is understood to mean the portion of the profile which forms the end of the profile in its longitudinal direction.

<Desc / Clms Page number 7>

 By external face of the first profile means the face of the first profile which is oriented towards the outside and receives the second profile. The external face can in particular be formed by the external peripheral face of the first profile, which is formed, in the case of an oblong quadrangular body, by four longitudinal faces oriented towards the outside. In the case of an oblong body or an oblong profile with an L-shaped cross section or any other cross section, an external face is defined by the fact that the second profile is attached to this external face of the first profile.

 In addition, the internal face is defined according to the invention by the fact that it is formed inside the first profile. In the case of a hollow profile, the internal face is the face which delimits the cavity of the first profile. For other embodiments of a first profile, the internal face of the first profile is defined by the fact that the fixing device is totally or partially engaged with said internal face. If the first profile is a longitudinal profile of cross section in L, the internal face is defined by the longitudinal face (s) which are opposite the second profile, seen in the longitudinal direction of the latter , when attached to the first profile. The internal face can thus form part of or delimit a cavity or also form part of an external face of a first profile without constituting a cavity.

<Desc / Clms Page number 8>

 In addition, according to a first embodiment, the first profile has at least one hole which delimits the internal face, said hole passing through the openings of the first profile and being able to receive the fixing device. The fixing device can therefore be guided by the drilling, so that the locking of the two projections is easy to ensure and that a stable connection is obtained between the first and the second profiles.

 According to a second embodiment, the fixing device has an angular assembly body which can be engaged from the outside in the first profile and which has at least one housing which delimits the internal face and can receive part of the second profile. The housing formed in the angular assembly body makes it possible to improve the stability of the connection by angular assembly body between the first profile and the second profile.

 Other advantageous embodiments of the invention are defined in the claims. It is thus particularly advantageous that when the first profile is in contact with the second profile, the recess is at least partially in the space delimited by the internal face. The fixing device can then be blocked between the internal face and the recess to connect or fasten in a simple way two sections.

<Desc / Clms Page number 9>

 It is also advantageous that during the assembly of the first profile with the second profile, the recess is offset from the opening so that when it is inserted into the recess, the fixing device is locked in position by the first profile. It is essential in this regard that there is a defined offset between the position of the recess before and the position of the recess after insertion of the fixing device in order to obtain, between the first profile and the second profile, a stable connection to positive engagement by insertion of the fixing device.

 It is also advantageous that the first profile has two openings on one of its longitudinal faces at the level of the angular assembly and that the second profile has a second recess arranged in such a way that the fixing device blocks the two recesses. The presence of the two recesses improves the connection between the first and the second profiles and thereby in particular the rotation blocking of the second profile relative to the first profile.

 According to one embodiment of the invention, the second profile has on its front end at least one projection, at least part of the recess being formed in the projection. The second profile can thus be in contact with the first profile essentially by its front end, only the projection passing through the opening of the first profile. By projection means a projecting portion, so that one also obtains on the second profile recessed portions, which are delimited in particular by the projection.

<Desc / Clms Page number 10>

 It is in particular advantageous that the fixing device serving to lock in position two projections is inserted in the two recesses of the second profile. The presence of the two projections makes it possible to obtain a connection of simple and reliable design between the first and the second profiles.

 If, to block the two projections, the fastening device can be engaged with the recesses in the longitudinal direction of the first profile so that the first profile and the second profile are detachably connected together forming the angular assembly , a removable connection is obtained between the first profile and the second profile, for example by blocking the two projections by means of a fixing sleeve, a tenon or a rivet inserted in the two recesses of the projections . This can be done simply by forcibly engaging or driving the fixing device, namely the fixing sleeve, the tenon or the rivet, by means of a hammer. Fixing can also be ensured by means of a screw connection as a fixing device.

 To remove, if necessary, the fixing devices after completion of the connection, the fixing sleeve, the tenon or the rivet can be driven out of the recesses of the two projections by striking above in the longitudinal direction of the first profile. You can also remove the connection by extracting the screw from the recesses. An advantageously removable angular assembly is thus produced simply and with a minimum number of elements.

<Desc / Clms Page number 11>

 allow if necessary to separate non-destructively the first profile from the second profile.

 According to a preferred embodiment of the invention, the fixing device is arranged with a tight fit in each recess of the two projections.

 According to another advantageous embodiment of the invention, the bore is formed centrally in the first profile, the two pairs of openings each extending from a longitudinal face of the first profile to the central bore. It is thus possible to connect two second profiles to a first profile by inserting a single element in the central bore. To do this, a screw is inserted in particular from the outside into the bore of the first profile, said screw passing through the four recesses and being screwed onto the first profile.

 It is also advantageous that the two openings formed in a first longitudinal face are offset in height relative to the two openings formed in a second longitudinal face of the first profile. Indeed, it suffices to differentiate the openings, the second profiles used can be identical. This offset arrangement of the openings allows up to four second profiles to be attached to a first profile, each second profile being able to be fixed at the level of the central bore.

<Desc / Clms Page number 12>

 Preferably, the two projections of a second profile are arranged asymmetrically with respect to the median axis of the second profile. As a result, second profiles having an identical end can be arranged side by side by simple rotation of the second profile and can be fixed by means of a single screw.

 According to an advantageous embodiment, the second profile has a first end with recesses which are offset from the recesses of its second end by a distance equivalent to the thickness of the recess. This arrangement makes it possible to arrange four second profiles in the same plane if there is attached to each first profile and fixed by means of a screw in the central bore a first end of a second profile and a second end of another second profile.

 According to another embodiment, the fixing device is locked in the two recesses of the projections by means of an eccentric element, the eccentric element allowing in a first angular position to insert the projections and in a second angular position to block the two recesses. This provides a quick removable connection to establish and undo.

 In a preferred embodiment of the present invention, the angular assembly body is pre-assembled in the first profile as an element of said first profile, so that the first profile can be delivered with the body

<Desc / Clms Page number 13>

 angle assembly inserted at the factory. The angular assembly device can therefore, in this embodiment also, be manufactured from only three elements delivered.

 It is also advantageous for the angular assembly body to have two housings each receiving one of the projections of the second profile.

 If the angular assembly body has an angular assembly body bore which is oriented in its longitudinal direction, delimits the internal face, connects the two housing of the projections and is entirely cut by each housing, a fixing means which can be inserted in the drilling of the angular assembly body so that the fixing device is formed by the angular assembly body and the fixing means, then a particularly stable connection can be obtained thanks to the angular assembly body and the fixing means inserted into its angular body piercing. The fixing means used in this case is preferably a fixing sleeve, a tenon, a rivet or a screw.

 It is also advantageous that the angular assembly body inserted in the first profile can be connected to a second profile by its face in contact with the corresponding face of the first profile. The angular assembly body thus makes it possible to fix not only 1 but 2, 3 or 4 second profiles to a first profile.

<Desc / Clms Page number 14>

 According to an advantageous embodiment, the interrupted drilling of the angular assembly body and / or the recesses are offset so that the fixing device is blocked against the two recesses due to said offset. Since the recesses and / or the interrupted drilling of the angular assembly body are offset from each other, at least part of the drilling of the angular assembly body or one of the two recesses is arranged in such a way so that it is not possible to precisely align the drilling of the angular assembly body and the recesses of the second profiles. When the fastening device is inserted into the interrupted bore of the angular assembly body and into the two recesses, the fastening device or the fastening sleeve is deformed so that, thanks to the fastening device, , a link without play and by adhesion between the first profile and the second profile and thereby a stable angular assembly.

 The fixing device is or advantageously comprises a fixing sleeve, a tenon, a rivet, a screw or an angular assembly body. In particular, the fixing sleeve is, according to an advantageous embodiment, consisting of a spring steel tube open on one side so as to be able to deform appropriately.

<Desc / CRUD Page number 15>

 According to an advantageous embodiment, the first profile and / or the second profile consists (s) of a hollow profile with an external contour and an internal contour, so that the cavity of the hollow profile defines the internal face.

This arrangement also makes it possible to obtain a stable and light angular assembly device.

 It is also advantageous that the fixing device is formed so that it crosses, if necessary, a surface coating at least at a defined point of the projection of the second profile and inside the first profile to establish an electrically conductive connection between the first profile and the second profile. The fixing device can therefore be used to earth the housing or the housing frame, the fixing device possibly having in particular a rib with a sharp edge for piercing the surface coating.

 A covering cap can also be attached to the first profile, said cap being able to be fixed by engagement with the internal face. The internal face can thus be used both to fix the fixing device and to fix the covering cap.

 Another advantage lies in the fact that the covering cap has at least one stud capable of being inserted into the longitudinal bore, so that the angular assembly body can be used to fix the fixing device and the covering cap.

<Desc / Clms Page number 16>

 If the cover cap has a guide element capable of being inserted into the internal face or a cavity of the first profile, a reliable connection is obtained between the fixing device and the cover cap, the stud of the cover cap being able in particular to be more easily inserted into the longitudinal hole.

 According to an advantageous embodiment, the covering cap makes it possible, on the one hand, to cover a first profile and, on the other hand, to fix a cover. By attaching the cover cap, it is thus possible in a single operation to cover the angular assembly and to fix the cover to said angular assembly.

 The cover cap can only be removed from the first profile if the latter is accessible from the inside once mounted, for example if a door of a housing composed of angular assembly devices is open.

 As is apparent from the above, the cover cap must be considered as an innovation independent of the angular assembly device and of the housing and has advantages even without the latter.

 An advantageous embodiment of a housing frame or housing according to the invention comprises a cover composed of a cover plate having a plurality of cover perforations and a foam mat. The hood perforations are used in this case to guide cables for example or to add a ventilation system, the foam being cut accordingly and serving as a seal in order to protect

<Desc / Clms Page number 17>

 inside the humidity case. To do this, the foam is preferably made of polyethylene.

 As is apparent from the above, the cover must be considered as an innovation independent of the angular assembly device and of the housing and has advantages even taken in isolation, without the above-mentioned elements.

Description of the examples of execution of the invention
Figure 1 shows a perspective view of a first embodiment of an angular assembly device for cabinet frame or housing according to the present invention.

<Desc / Clms Page number 20>

 The angular assembly device of Figure 1 comprises a first profile or longitudinal profile 10 internally hollow and having on two of its longitudinal faces, at the angular assembly, a pair of openings 11 in the form of slots. The longitudinal section 10 has an open end 16 accessible from the outside or an end portion 17, provided at the angular assembly. The angular assembly also comprises a second profile or transverse profile 20 which is internally hollow and having on its front face two projections 21 in U formed integrally with the second transverse profile 20.

In each projection 21 is formed a recess 22 in the form of a bore. The recess 22 is in particular formed in an end region 28 of the one-piece transverse profile 20. The angular assembly device further comprises a fixing device 30 which, in the embodiment of FIG. 1, is presented under the form of a fixing sleeve 31, for fixing the two projections 21 so that the fixing sleeve 31 is blocked in the recesses 22 when the projections 21 of the transverse profile 20 are inserted in the openings 11 of the longitudinal profile 10. thus obtains an angular assembly by connection of the longitudinal profile 10 with the transverse profile 20 by means of the fixing sleeve 31. The fixing device 30 is for this purpose engaged, in the end region 17 of the longitudinal profile 10, which, at this level, is hollow or has a cavity 16, with an internal face 19 formed by the internal contour 19 of the longitudinal profile 10. Due to the cavity 16, the longitudinal profile present, in addition to the outline

<Desc / Clms Page number 21>

 internal 19, an external contour 18 in the form of external faces 18 against which are pressed, during assembly, recessed portions 26 of the transverse profile 20.

 The assembly operation of the angular assembly is explained below. The transverse section 20 is advanced in the direction of the arrow towards the longitudinal section 10 until the projections 21 pass through the openings. 11 of the longitudinal section 10 and the two recesses 22 are located inside the cavity 16 of the vertical profile 10. The openings 11 are in this case formed so as to extend as far as the interior of the cavity 16. Then, the fixing sleeve 31 is introduced from the top, in the direction of the arrow, in the cavity of the longitudinal section 10 so that the fixing sleeve 31 is inserted or driven, for example using a hammer, in the two recesses 22 of the transverse section. The fixing sleeve 31 then locks in the two recesses 22 and against the internal face 19, so that the two projections 21 are fixed in the openings 11 of the longitudinal section, the external face 18 then coming into contact with the recessed portions 26. The fixing device 30 is then engaged with the recesses 22 and the internal face 19. This gives an angular assembly device composed of a minimum number of elements and which can be manufactured quickly and at low cost because the simplicity of the assembly operation.

<Desc / Clms Page number 22>

 If it is necessary to separate the transverse profile 20 from the longitudinal profile 10, it suffices to strike the fixing sleeve 31 by means of a tool adapted to drive it from the recesses 22 from below, so as to allow the projections 21 of the openings 11 to completely undo the assembly.

 FIG. 2 shows a perspective view of a second embodiment of the angular assembly device according to the invention, which essentially corresponds to the embodiment of FIG. 1.

 The angular assembly device of FIG. 2 comprises a transverse section 120 which has the general shape of a U and has a projection 121 on the two parallel faces of the transverse section at the front ends thereof. The transverse profile thus comprises four projections 121 each having a recess 122.

<Desc / Clms Page number 23>

 The angular assembly device of FIG. 2 further comprises a longitudinal profile 110 comprising, at the level of the angular assembly, on two of its longitudinal faces, a pair of parallel openings 111 spaced apart from each other by a defined distance. The main difference compared to the embodiment of Figure 1 is that the side walls of the longitudinal section 110 each have a reinforcement 112 at the openings 111. This reinforcement is provided at least at the two openings 111 .

Inside the reinforcement 112 is formed a longitudinal bore 113, which extends at least to the two openings 111 and forms the internal face. Since the two openings 111 also each cut the reinforcing element 112, the longitudinal bore 113 is completely cut by the two openings or slots 111. This is particularly useful in particular for the insertion of a fixing device 30 under the form of a stud 130 or of a rivet because the stud 130 is reliably guided by the longitudinal bore 113.

 The assembly of the angular assembly device of FIG. 2 is carried out in a manner substantially analogous to that of the angular assembly device of FIG. 1, the tenon 130 being simultaneously introduced or pressed into the longitudinal bore 113 and into the recesses 122 It is particularly advantageous to obtain a tight fit between the post 130 and the recesses 122 as well as, preferably also, in the longitudinal bore 113.

<Desc / Clms Page number 24>

 If another longitudinal profile 110 is added identically to the right side of the transverse profile 120 (in FIG. 2), it is for example possible to obtain in this way a cabinet frame, on which walls and doors to build a cabinet.

 Figure 3 shows a perspective view of a third embodiment of the angular assembly device according to the invention. This embodiment makes it possible to fix two transverse profiles 220 to a longitudinal profile 210 by means of a single fixing device 230. The two transverse profiles 220 have, on a front face, two parallel projections 221, spaced apart from one another. another of a predefined distance and each provided with a recess 222 opposite. The longitudinal section 210 also has on two of its longitudinal faces a pair of openings 211 spaced from each other by a corresponding distance. In terms of distance from the front end of the longitudinal section 210, the arrangement of the openings 211 on one of the longitudinal sides of the section 210 is different from that of the two openings 211 on the other longitudinal side of the longitudinal section 210. In in addition, the projections 221 each extend so that the recesses 222 of the two transverse sections 220 can be located on the axis of symmetry of the longitudinal section 210. Therefore, the recesses 222 of one of the transverse sections 220 are aligned with those of the other transverse profile 220 when the respective projections 221 are fully inserted into the openings 211 of the longitudinal profile 210. To do this, the openings 211 are offset in height or the projections 221 are arranged in a differentiated manner.

<Desc / Clms Page number 25>

 The longitudinal profile 210 also has, along its axis of symmetry, a central bore 213 arranged in the center of the cavity of said longitudinal profile 210 by means of different ribs 214 and forming the internal face. Thus, during assembly, each recess 222 of the two transverse sections 220 is aligned with the central bore 213. The openings 211 each extend for this purpose up to the central bore 213. Therefore, a single device is sufficient of fixing or of a single element to connect the two transverse profiles 220 to the longitudinal profile 210.

In accordance with FIG. 3, this single fixing device 30 is in the form of a screw 230 which assures the angular assembly by screwing. The loosening of the screw makes it possible to separate the longitudinal profile 210 from the two transverse profiles 220. However, it appears that the screw 230 can also be replaced by a stud or a rivet or any other similar element.

 Figures 4a to 4c further show a perspective view of a fourth embodiment of the angular assembly device according to the invention.

 FIG. 4a shows a cross-sectional view of the fourth embodiment of the angular assembly device with a transverse profile 20 and a longitudinal profile 10, which are connected by means of a fixing device 30 which is present under the form of an eccentric element 330. The fourth embodiment corresponds in this respect substantially to the first embodiment, except that an eccentric element 330 is arranged in the recesses 22.

<Desc / Clms Page number 26>

 As can be seen in FIG. 4a, if the eccentric element 330 is rotated around its longitudinal axis, the transverse profile 20, due to the eccentricity, moves in the direction of the longitudinal profile 10 along the longitudinal arrow . The transverse profile 20 is therefore fixed to the longitudinal profile 10 by rotation of the eccentric element, as shown in Figure 4b.

 If one turns in the opposite direction to the direction defined for the fixing, the transverse section 20 moves away again from the longitudinal section 10 to remove the fixing.

 Figure 4c shows a perspective view of the fourth embodiment, a cover cap 40 being arranged at the front end of the longitudinal profile 10. The cover cap 40 has an opening through which the drive mechanism in rotation of the eccentric element 330 can be actuated. It is thus possible to fasten or separate the transverse profile 20 from the longitudinal profile 10 even if the longitudinal profile 10 is capped with a cover cap 40.

 FIGS. 5a and 5b each show a perspective view of an embodiment of a fixing device in the form of an angular assembly body 50 for the angular assembly device according to the invention. Figures 6a and 6b further show respectively a cross-sectional and perspective view of the embodiments of the fixing device in the form of the angular assembly body shown in Figures 5a and 5b, Figure 6a showing a view

<Desc / Clms Page number 27>

 in cross section of the angular assembly body of Figure 5a and Figure 6b showing a cross-sectional view of the angular assembly body 50 of Figure 5b.

 The first embodiment, shown in perspective in Figure 5a, of the angular assembly body 50 used as a fixing device has on each of its longitudinal faces two housings in the form of openings 51 formed in the wall of the body angular assembly 50, capable of receiving the projections 21 of the transverse profiles 20. The angular assembly body 50 is designed in the form of a rectangular hollow profile, the housings each having an extension 52 capable of being engaged with a recess 22 of the transverse profile 20 to ensure the fixing. The extensions 52 extend for this purpose from the wall of the angular assembly body 50 as far as the region of the opening-shaped housing 51. The extensions 52 extend in the longitudinal direction downwards as shown in FIG. Figure 5a. In addition, the extensions 52 are round and chamfered to allow or carry out the insertion and blocking of the extensions 52 in the recesses (not shown in FIG. 5a).

 In Figure 6a, which shows the angular assembly body of Figure 5a in cross section, the extension 52 is shown in the cutting plane. It therefore clearly appears that the extension 52 projects into the opening of the housing 51.

<Desc / Clms Page number 28>

 The second embodiment of an angular assembly body 150 used as a fixing device is shown in perspective in FIG. 5b, an extension 152 arranged in alignment with the external face of the angular assembly body 150 being formed as part of a housing 151. For the rest, the second embodiment of the angular assembly body 150 of Figures 5b and 6b is substantially similar to the first embodiment illustrated in Figures 5a and 6a.

 Figure 6b shows the cross-sectional view of the angular assembly body 150 of Figure 5b. It can be seen in this figure that the extension 152 is formed in alignment with the wall of the hollow profile of the angular assembly body 152. The opening of the housing 151 consequently affects the shape of a U.

 Figures 7a to 7c show perspective views of an angular assembly device according to the invention with an angular assembly body 50 corresponding to the first embodiment of Figures 5a and 6a.

 It can be seen in FIG. 7a that a transverse profile 520 of cross-section, in a U-shape is fixed in a longitudinal profile 510 by means of the angular assembly body 50. The longitudinal profile 510 also has wings 531 and 532 on which can be added for example side walls, doors or even sealing elements.

<Desc / Clms Page number 29>

 Figure 7b shows the angular assembly device of Figure 7a seen in cross section. It can be seen there that the two extensions 52 of a longitudinal face of the angular assembly body 50 are engaged in the recesses 522 of the transverse profile 520. It can also be seen that if the angular assembly body of FIG. 7b is lifted towards at the top, the recesses 522 of the projections 521 are no longer engaged with the extension 52, so that the transverse profile 520 can be released from the longitudinal profile 510.

 FIG. 7c, which is a perspective view of the angular assembly device of FIGS. 7a and 7b, shows that the angular assembly body 50 can move freely in the cavity of the longitudinal profile 510. To establish the connection between the transverse profile 520 and the longitudinal profile 510, the angular assembly body 50 is inserted into the longitudinal profile 510 until the housings 51 are at the level of the openings 511, so that the projections 521 can engage at the same time in the openings 511 and in the housings 51. We then continue to lower the angular assembly body 50 vers.le transverse profile 520, so as to introduce the extensions 52 in the recesses 522 of the transverse profile 520. This gives a removable connection of the transverse profile 520 with the longitudinal profile 510 by means of a single element, namely the angular assembly body 50.

 FIG. 8 shows a perspective view of a cabinet frame 500 according to the invention with added elements. Figure 8 shows in particular

<Desc / Clms Page number 30>

 an exploded view of a cabinet, lateral elements 560 being attached to the cabinet frame 500 for example by means of a plug connection 561, as shown by the arrows. A door 570 is also attached to the cabinet frame 500.

 The various transverse 520 and longitudinal 510 sections of the cabinet frame are interconnected by means of angular assembly devices according to the invention, which FIG. 8 does not show in detail, however.

 The longitudinal sections 510 and transverse sections 520 are generally provided with perforations, for example 9.5 x 9.5 millimeters, at the level of which the mounting devices necessary for receiving the components and systems of telecommunications and data processing for example can be attached in particular by quick coupling.

 In addition, a cover 580 must be attached to the cabinet frame 500, the seal being ensured by a mat 581 inserted between the cover 580 and the cabinet frame 500. The cover 580 also has a plurality of perforations of cover 582 to allow the passage of conductors, for example inward and outward of the housing. Furthermore, the front faces of the longitudinal sections 510 are capped with cover caps 40, the pins of the cover caps 40 being inserted, after mounting of the angular assembly device, into the longitudinal bore of an angular assembly body at by means of a hammer for example, which has the effect of simultaneously fixing the cover 580 to the housing.

 Figure 9a shows a perspective view of an embodiment of a longitudinal section 610 for the angular assembly device according to the invention. The longitudinal section 610 has, on two of its longitudinal faces 613 which form the external faces 613 of the longitudinal section, a pair of openings 611 in which the projections of a transverse section engage (not shown in FIG. 9a) . The openings 611 are formed at the upper and lower front ends of the longitudinal section 610 to form at these levels an angular assembly. The longitudinal profile 610 also has a row of discrete perforations 612. This row of perforations 612 can for example be used to fix the lateral elements of the cabinet.

 In addition to the two longitudinal faces 613, which have the openings 611 and the perforations 612, the longitudinal section 610 comprises a second hollow portion 614 and three stages, which are not decisive for the operation of the longitudinal section 610.

 FIG. 9b represents a top view of the longitudinal profile 610 making it possible to see the two longitudinal faces 613, the second hollow portion 614 as well as the external and internal contours of the longitudinal profile 610 and the three stages of the longitudinal profile 610. The longitudinal profile 610 is symmetrical about the axis of symmetry 616.

 FIG. 10a shows a perspective view of a transverse section 620 of the angular assembly device according to the invention, the transverse section 620 having, on each of its front faces, a pair of projections 621 in which the recesses 622 are made preferably by punching. The transverse profile 620 also has a row of discrete perforations 623 at the level of which can be added, for example, lateral elements of the cabinet.

 Figure lOb shows a top view of the transverse section 620 of Figure 10a. The special geometric shape of the transverse section 620 is not, however, essential for understanding the invention and will therefore not be the subject of a more detailed description. It appears however that one can also use as transverse profile 620 an open profile of practically any shape.

 FIG. 11 shows a perspective view of an angular assembly body 250 and of a covering cap 40 of an angular assembly device according to the invention. The angular assembly body 250 preferably consists of an injected one-piece but can also be made of a pressurized alloy or other similar material. The angular assembly body 250 has, on its two external edges, a pair of recesses 255 whose function is to ensure that sealing elements not shown can go from one profile to another. In the middle of each of the two longitudinal faces 256 of the angular assembly body 250 is provided a drilling of angular assembly body or longitudinal drilling 253,

<Desc / Clms Page number 33>

 which extends in the longitudinal direction over the entire length of the angular assembly body 250 and forms the internal face 253. The longitudinal profile 610 can in particular be pre-assembled with the angular assembly body 250 or be made in one piece with the latter .

 The cover cap 40 is advantageously made of plastic and essentially comprises a cover surface 43, two pins 41 and a guide element 44. The guide element 44 is used to place the cover cap 40 against the internal contour. of a longitudinal section, the guide element 44 also serving to clip and fix the covering cap 40. The pins 41 of the covering cap 40 also serve to fix the covering cap and are in particular pressed into the longitudinal bores 253 of the angular assembly body 250.

 The longitudinal holes 253 thus serve on the one hand to fix the covering cap 40, the two pins 41 of the covering cap 40 being pressed into the longitudinal holes 253, as shown by the arrow in FIG. 11. The longitudinal holes 253 serve on the other hand to receive a fixing device or a fixing sleeve or another element, as will be explained in more detail below.

<Desc / Clms Page number 34>

 It should also be mentioned that there are also provided, in addition to the holes 253, other holes oriented in the longitudinal direction of the angular assembly body 250. However, these are of no interest for the operation of the angular assembly device .

 As it appears in FIG. 12, which shows a perspective view of the angular assembly body 250 and of the covering cap 40 of FIG. 11, this time seen from below, the angular assembly body 250 present on each of its longitudinal faces 256 a pair of housings 251 into which can be inserted projections of a transverse profile. The housings 251 completely cut the longitudinal bore 253 so that, for example, each fixing sleeve inserted in the longitudinal bore 253 can pass through two recesses in two projections of a transverse section not shown in FIG. 12. This will be explained in more detail in relationship to Figure 13.

 FIG. 12 represents the covering cap 40 in a view in which the external face of the covering surface 43 and only part of the stud 41 and of the guide element 44 are visible.

 FIG. 13 shows a partially exploded perspective view of an angular assembly device according to the invention making it possible to see the mounting of the angular assembly devices from the different elements. This is also shown in individual sequences in the figures

<Desc / Clms Page number 35>

 14 and 15. Figures 13 to 15 show the mounting of the various elements of the angular assembly device which are shown as independent elements in Figures 9 to 12 and are described in connection with these figures.

 Firstly, the angular assembly body 250 is pushed in or inserted into the longitudinal profile 610 of FIG. 9a until the housings 251 of the angular assembly body 250 are at the same level as the openings 611 of the longitudinal profile 610 (see fig. 15). This arrangement of the angular assembly body 250 in the longitudinal profile 610 is illustrated in FIGS. 14 and 15. Next, the projections 621 of the transverse profile 620 are inserted both into the openings 611 of the longitudinal profile 610 and into the housings 251 of the angular assembly body 250, as shown by the arrow on the lower transverse profile 620 in FIG. 13. FIG. 13 also shows a second upper transverse profile 620, which can be attached to the other longitudinal face 613 of the profile longitudinal 610 in the same manner as that described above for the lower profile 620. The lower transverse profile 620 attached to the longitudinal profile 610 is shown in phantom in Figure 13 and is designated by the reference 620 '.

 Then, as shown in FIG. 15, the fixing device 30 which, in the embodiment, is introduced into or inserted into the longitudinal bore 253 of the angular assembly body 250, for example by means of a hammer. shown in Figures 13 to 15, is in the form of a mounting sleeve 430 combined with the body

<Desc / Clms Page number 36>

 angular assembly 250. When the fixing sleeve 430 is fully inserted into the longitudinal bore 253, a firm connection is obtained between the longitudinal profile 610 and the transverse profile 620 by means of the fixing device 30 which, in this embodiment, consists of the fixing sleeve 430 and the angular assembly body 250.

 If a second fixing bush 430 is now inserted into the other longitudinal bore 253 of the angular assembly body 250, the upper transverse section 620 (in FIG. 13) can be fixed in the same way to the longitudinal section 610 Thanks to this possibility, a flexible angular assembly device is obtained, making it possible to choose between an assembly of a longitudinal profile 610 and a single transverse profile 620 or an assembly between a longitudinal profile 620 and two transverse profiles 620.

 FIG. 14 represents a preferred variant embodiment of the invention. Figure 14 shows, seen from above, the longitudinal section 610 on which are reported the transverse section 620 and the angular assembly body 250, before driving in the fixing sleeve. In this preferred embodiment, it is essential that there exists, before insertion of the fixing sleeve 430, a defined offset between the recesses 622 of the two projections 621 and / or the interrupted longitudinal drilling 253 of the angular assembly body 250. Consequently, as shown in the enlargement of FIG. 14, the longitudinal bore 253 does not perfectly coincide with the recess 622 shown partially in broken lines. Because of this

<Desc / Clms Page number 37>

 defined offset, when the fixing sleeve 430 is pushed in, the transverse profile 620 is attracted towards the longitudinal profile. This makes it possible, on the one hand, to compensate for tolerances and, on the other hand, to obtain a stable assembly by positive engagement between the longitudinal profile 610 and the transverse profile 620.

 To separate the transverse profile 620 from the longitudinal profile 610, it suffices simply to drive the fixing sleeve out of the longitudinal bore 253 by means of a suitable tool.

The projections 621 of the transverse section 620 can then be removed from the openings 611 of the longitudinal section 610, so that the two sections can be spaced from one another.

 FIG. 15 shows the state in which the fixing device or the fixing sleeve 430 is before being driven, for example by means of a hammer, into the longitudinal bore 253 of the body angular assembly 250 to block the recesses. Due to the offset of the axes of the recesses relative to the longitudinal bore 253, the transverse profile 620 is brought closer to the longitudinal profile 610, so that the recessed portions of the transverse profile cooperate in support and by adhesion with the longitudinal profile 610. thus a particularly non-deformable angular assembly which can also be dismantled by driving out the fixing sleeve 430.

<Desc / Clms Page number 38>

 FIG. 16 shows another embodiment of a covering cap 140 serving to cover the end of a longitudinal section at the level of an angular assembly. The covering cap 140 essentially comprises a sealing surface 143, two pins 141 as well as a guide element 144. The guide element 144 is intended to be introduced at its peripheral surface in a cavity d 'a longitudinal profile, when assembling the covering cap 140 with a covering device.

 In addition, pins 141 of the cover cap 140 are inserted in the holes of the longitudinal section or, preferably, in the longitudinal bore of the angular assembly body.

The cover cap 140 is produced in the form of a single piece of plastic material and can be inserted, by means of a simple tool, for example a hammer, into the end of the longitudinal profile once the assembly of the fully assembled angular assembly. The cover cap 140 can then be clipped, by means of the clipping fingers 142, into the cavity of the longitudinal profile to establish a reliable connection with the longitudinal profile. The cover cap is for this purpose made of a suitable plastic material giving the clipping fingers 142 the desired flexibility, so as to allow the cover cap to be removed from the longitudinal section by application of an appropriate force to release the fingers d '' 142.

<Desc / Clms Page number 39>

 It is thus designed an angular assembly device for cabinet frame or housing which allows' to achieve an angular assembly of profiles by means of a minimum number of elements, the assembly time being limited due to the simplicity of mounting of the angular assembly.

 According to an embodiment not shown, the profiles may have an L-shaped cross section, so that they do not have a cavity but an internal face or contour and an external face or contour. It is also clear to a person skilled in the art that the face or the internal contour and the face or the external contour of the profiles can affect almost any geometry or shape, for example triangular, folded or polygonal.

 According to an embodiment not shown of the invention, the second profile can engage over the entire length of its edge in an opening or a slot in the first profile, so that the second profile has no projection. The recess must, in this case, be formed at one of the lateral edges of the second profile.

 It is also clear to those skilled in the art that other modifications can also be made. In particular, the fixing device can also have an arcuate, wedge-shaped or other similar shape.
