Description

FIELD OF THE INVENTION The invention relates to the field of cabinets for

  electrical appliances. The invention relates more particularly to a frame and a nut-clip mounted on a section belonging to the frame.

  BACKGROUND OF THE ART EP 0 402 276 discloses a sealed electrical equipment cabinet whose frame is constituted by identical profiles in the form of an angle whose edges are bent at right angles to form folds. Clips-nuts can be associated with these profiles in angle.

  OBJECT OF THE INVENTION The object of the invention is to improve this type of cabinet for electrical appliances.

  For this purpose, the invention relates to a cabinet for electrical appliances comprising a frame and a first nut-clip mounted on a profile belonging to the frame, characterized in that the section of the section comprises: a first straight section; - A second straight section disposed transversely to the first section and having a first end joined to a first end of the first section, the section of the profile corresponding to the second section having at least one orifice vis-à-vis the nut clip; a third straight section arranged opposite the first section and having a first end joined to a second end of the second section opposite the first end of the second section; - A fourth hairpin section having a first end joined to a second end of the third section opposite the first end of the third section so that the fourth section is located on the same side as the second section; A fifth straight section extending opposite and at a distance from the second section and having a first end joined to a second end of the fourth section opposite the first end of the fourth section; a sixth straight section disposed opposite the first section and the fourth section and having a first end joined to a second end of the fifth section opposite the first end of the fifth section; and in that the second section, the third section, and the fifth section, on the one hand, and the first clip-nut, on the other hand, are shaped so that the sections of the profile respectively corresponding to the second, third, and fifth sections delimit a first reception space of at least one end portion of the first clip-nut.

  The term "nut clip" means any device comprising a threaded portion and a clip or clip allowing the clip-nut to maintain its threaded portion against another part, generally vis-à-vis a fixing hole. The nut clips are also commonly referred to as nut clip or nut-clip.

  The profiles constituting the frame of such a cabinet are more compact thanks to the reception of a portion of the clip-nut in a reception space provided by the elements which also form the gutter associated with the profiles. Thanks to such more compact profiles, the frame of the cabinet is less bulky and therefore frees up the space inside the cabinet.

  DETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT FIG. 1 shows a parallelepipedic reinforcement 1 formed of an assembly of sections 2, 3. The sections 2, 3 are generally metallic but may be made of any material having the required mechanical properties. This armature 1 is intended to receive on each of its faces a panel attached to the sections 2, 3 to form a cabinet for electrical devices. In the present example, the armature 1 comprises a lower frame 4 and an upper frame 4, these two frames 4 being rectangular and each consisting of an assembly of four profiles of the same section called sleepers 3. The lower and upper frames 4 are interconnected by four vertical sections 2 hereinafter referred to as amounts. The junction of one of the uprights 2 with a corner of the lower frame 4 (at the level of the box II) is shown in FIG. 2. This view corresponds to a view from the inside of the cabinet and makes it visible. internal corner of the corner of the frame 4 which is shown here. The uprights 2 and crosspieces 3 comprise notches 24, 64 facing the inside of the cabinet and adapted to receive clips-nuts 6 for mounting the interior equipment of the cabinet with screws (not shown ). FIG. 3 shows the assembly of an upright 2 and of the lower frame 4 at the level of the inset III of FIG.

  This view corresponds to a view from outside the cabinet and makes visible the outer corner of the corner of the frame 4 which is shown here. The tightness of the assembly is provided by a seal 7 whose shape partially matches the shape of the two assembled parts. Figure 4 is an exploded view of the elements shown in Figure 3, that is to say, the amount 2 is shown separated from the frame 4 whose outer corner is visible. This FIG. 4 shows that the upright 2 comprises an interlocking nut 8 represented vis-à-vis an interlocking section profile 9 with a square section in which the interlocking nut 8 is intended to fit together, the nut interlocking 8 and the interlocking profile 9 having complementary shapes allowing this interlocking force. A tie rod 10 makes it possible to hold the assembly of the upright 2 and the frame 4. The tie rod 10 is, in the present example, a screw passing inside the interlocking profile 9 and screwing itself into a tapping made in the nut 8. A wedge washer 11 distributes the tightening forces of the tie rod 10 to the frame 4. This seal 7 is shown alone, in perspective, in Figures 5 and 6, respectively in bottom view and in view of above. This seal 7 comprises a square frame 12 adapted to match the outer shape of the interlocking profile 9, a lip 13 disposed at one of the corners of the square frame 12 and two wings 14 each provided with a rim 15. The seal 7 further comprises, at the flanges 14, two fasteners 16 intended to cooperate with holes 17 of the frame 4 (see Figure 7) to fix the seal 7.

  Figure 7 shows in perspective the outer corner of a corner of the frame 4 after the amount 2 and the seal 7 have been removed. This corner of the frame 4 is thus formed by the assembly of the two identical crosspieces 3 whose end of each is cut at 45, the profile 9 being fixed at this assembly of the two ends of the crosspieces 3 cut at 45, between the internal angle and the outer corner of the corner of the corresponding frame 4. Figures 8 and 9 are views respectively of profile and front of the frame 4.

  As shown in Figures 8 and 9, the four corners of the frame 4 are identical to the corners shown in Figure 7. Figure 10 is a view of the inside of the corner of the frame 4 showing the internal angle of this corner. The frame of FIGS. 7 to 10 is formed of crosspieces 3 in accordance with FIG. 11. The profile forming the crosspiece 3 of FIG. 11 has corner cutouts at 45, so that four sections 3 comprising such cutouts can be assembled. to form the frame 4. Figures 12 and 13 show in perspective of the profiles 3 so that their end cutouts at 45 are visible.

  Referring to Figures 11, 12 and 13, each end of the crosspiece 3 being cut at 45, the portion of the crossbar 3 which carries the notches 24 has an additional cutout 115 so that this portion is cut in turn perpendicular to the direction in which extends the cross 3. A support tongue 116 for carrying the hole 17 for fixing the seal 7 is further provided. To form for example the corner of Figures 7 and 10, the two crosspieces 3 of Figures 12 and 13 are arranged perpendicularly end to end. An interlocking profile 9 is then placed at the corner, the whole being held by an external weld 18 (see FIG. 7) and by an internal weld 19 (see FIG. 10). Referring to Figure 7, the outer weld (18), made on the outer corner of the corner of the frame 4 shown here, comprises a portion 18 'welding both ends of the two crosspieces 3 shown here and the profile of interlocking 9.

  Referring to Figure 10, showing the internal angle of a corner of the frame 4, the inner weld 19 has a portion 19 'welding both the end of the two crosspieces 3 shown here and the interlocking profile 9 The remainder of the weld 19 welds only the ends of the two sleepers 3.

  FIG. 14 is a view of the section of the crosspieces 3. The crosspieces 3 thus comprise, in section: a first straight section comprising a first end 27 and a second end 51, holes 21 being arranged regularly on the section of the profile; corresponding to this first section (see Figure 12) and intended for the passage of a screw; a second section 22 right disposed perpendicularly to the first straight section 20 and having a first end 26 and a second end 28, the first end 27 of the first section 20 being connected to the first end 26 of the second section 22 at a crease , holes 23 for the passage of screws being regularly arranged on the section of the profile corresponding to this first section 20. The first section 20 and the second section 22 comprise, at their junction, notches 24 (see Figure 12); a third straight section disposed perpendicularly to the second section 22, on the same side as the first section, and having a first end connected by a fold to a second end of the second section; a fourth hairpin section 30 having a first end 31 connected by a fold to a second end 32 of the third section 25 so that the fourth section 30 is located on the same side as the second section 22, the fourth section thus running along partly the third section 25; a fifth straight section 33 extending opposite and at a distance from the second section 22 and disposed perpendicularly to the third section 25, this fifth section 33 having a first end 34 connected by a fold to a second end 35 of the fourth section; section 30, the fifth section 33 being here parallel to the second section 22, the fifth section 33 extending at a distance from the second section 22, a receiving space 5 is thus formed between the sections of the cross member 3 corresponding to these second 22 and fifth 33 sections; - A sixth section 36 right disposed perpendicularly to the fifth section 33, on the same side as the fourth section 30, and having a first end 37 connected by a fold to a second end 38 of the fifth section 33; - A seventh section 39 hairpin having a first end 40 connected by a fold to a second end 41 of the sixth section 36 and having a second end 42 juxtaposed to the first end 40 of the seventh section 39; - Eighth section 43 right having a first end 44 connected by a fold to the second end 42 of the seventh section 39; a ninth section 45 bent having a first end 46 connected by a fold to a second end 47 of the eighth section 43 and a second free end 48, the ninth section 45 having a bend 49 so that a portion of the ninth section 45 is disposed at the same level as the middle of the seventh section 39 in the form of a hairpin. The section of the profile corresponding to the ninth section 45 further comprises holes 50 for the passage of a screw and holes 118, of smaller diameter, possibly for receiving a clip-nut. The notch 24 defines on the second section 22 a stop surface 111 and delimits on the first section 20 a stop surface 112. In the present example, the first section 20 and the sixth section 36 are parallel and the second section 22 and the eighth section 43 are parallel. The first section 20 further comprises, at a second end 51, an angle 52 forming a fold parallel to the first section 20. The fourth section 30, the fifth section 33 and the sixth section 36 25 cooperate to form a gutter. Indeed, the surface of the pan corresponding to the fifth section 33 forms a flow surface for water or other fluid to be diverted from the inside of the cabinet, while the fourth section 30 and the sixth section 36 form the side flanks of this gutter. Each crosspiece 3 has an opening 117 between the angle 52 and the eighth section 43, the portion 19 'of the weld 19 being located in this opening 117 (see Figure 10). The part of the crosspiece 3 corresponding to the eighth section 43 forms a horizontal bearing surface for the interlocking profile 9. The interlocking profile 9 is further arranged laterally against the end of the crosspiece 3 corresponding to the sixth section 36, and this for each of the two sleepers 3 with which the interlocking profile 9 is in contact. The frame 4 of FIG. 9 forms, in the present example, indifferently the lower or upper frame of the frame 1 shown in FIG. 1. FIG. 15 shows the section of the frame 4 when it is used as a lower frame. The crosspieces 3 are fixed to the ground by means of a screw 53 passing through the hole 50. An aperture plate 54 can cap the screw 53 and separate the interior of the cabinet from the ground.

  A panel 55 is fixed on the crosspieces 3 and / or the uprights 2 to close the lateral openings of the cabinet in a sealed manner thanks to the seal 56. The space 57 makes it possible to house the head of the tie rod 10 intended to be inserted into a hole 58 of the section of the profile corresponding to the eighth section 43.

  The section 39 allows a complementary ground support of the section 45. In the present example, the upper and lower frames 4 are identical. Figure 16 is a view similar to Figure 15 except that it relates to the upper frame.

  Referring to this Figure 16, a roof 59 is fixed against the side of the cross member corresponding to the ninth section 45 by means of screws (not shown) cooperating for example with the holes 118. A roof seal 61 seals the roof. inside the cabinet. The panel 55, which already cooperates with the lower frame 4 (see FIG. 15), also co-operates with this upper frame thanks to a lateral seal 62. The cooperation of this lateral seal 62 with the crosspiece 3 of the upper frame 4 allows the panel to the cross member corresponding to the fifth section 33 to play its role of gutter by channeling any fluid that would enter the opening 63 left between the roof and the side panel 55, and preventing this fluid from entering the interior of the cabinet. The space 57 allows here also the placement of the head of the tie 10. The amounts 2 of the frame 1 will now be described with reference to Figures 17 to 22.

  FIG. 17 shows the end of an upright 2 after it has been separated from one of the frames 4, in accordance with FIG. 4. The upright 2 is a profile comprising, in a manner similar to the struts 3, notches 64 and holes 60, 65 regularly distributed along its length.

  The interlocking nib 8 protrudes from the end of the upright 2 in a generally square section, the corners of this square section being spaced from the walls of the upright 2 by a thickness substantially equal to or slightly greater than that of the profile. In the present example, rivets 66 make it possible to fix the interlocking nut 8 in the upright 2. Other fastening means such as screws or crimping can be used in place of or in addition to the rivets 66 Each end of each upright 2 thus comprises an interlocking nut 8. FIG. 18 shows in perspective the upright 2 of FIG. 17 after the interlocking nut 8 and the rivets 66 have been removed, thus revealing the holes 67 of the rivets 66. Figure 19 shows the section of the amount 2. In section, the amount 2 comprises: - a first section 68 right; a second section 69 right disposed perpendicularly to the first section 68 and having a first end 70 connected to a first end 71 of the first section 68; - A third section 72 right disposed perpendicularly to the second section 69, on the same side as the first section 68, and having a first end 73 connected to a second end 74 of the second section 69; - A fourth section 75 hairpin having a first end 76 connected to a second end 77 of the third section 72 so that the fourth section 75 is located on the same side as the second section 69; a fifth straight section 78 having a first end 79 connected to a second end 80 of the fourth section 75, this fifth section 78 extending opposite and at a distance from the second section 69 and being arranged perpendicular to the third section 72 ; - A sixth section 81 right disposed perpendicularly to the fifth section 78, on the same side as the fourth section 75 and having a first end 82 connected to a second end 83 of the fifth section 78; - A seventh section 84 right disposed perpendicular to the sixth section 81, towards the first section 68, and having a first end 85 connected to a second end 86 of the sixth section 81; an eighth straight section 87 disposed perpendicularly to the seventh section 84 and having a first end 88 connected to a second end 89 of the seventh section 84; - A ninth section 90 hairpin having a first end 91 connected to a second end 92 of the eighth section 87 so that the ninth section 90 is located on the same side as the seventh section 84; - A tenth right section 93 arranged perpendicular to the eighth section 87 and having a first end 94 connected to a second end 95 of the ninth section 90, the tenth section 93 having a second end 96 connected to a second end 97 of the first section 68. section of the upright 2 of this example is arranged symmetrically with respect to the diagonal axis 98. The section of the upright 2 corresponding to the first section 68 comprises the holes 65 while the section of the upright 2 corresponding to the second section 69 comprises the holes 60. To form a cabinet for electrical equipment, the upright 2 is mounted in accordance with Figure 20 showing a corner of the cupboard in section along a horizontal plane. Referring to this figure 20, the side panel 55 (also present in Figures 15 and 16) is mounted against the side of the upright 2 corresponding to the third section 72. A seal 99 seals between the side panel 55 and the amount 2 so that the section of the upright 2 corresponding to the fifth section plays a role of gutter for the vertical flow of fluids. A door 100 is also mounted similarly to the side panel 55 against the section of the upright 2 corresponding to the tenth section. A seal 101 provides the same function as the seal 99 by allowing the vertical flow of fluids along the side of the upright 2 corresponding to the eighth section. The interior of the cabinet is thus sealed while the gutters channel the fluids flowing on the cabinet.

  The door 100 performs the same function as the side panel 55, except that it is mounted on hinges (not shown) and can therefore open and close. The length of the third section and the tenth section allows the sections corresponding to these sections to have a large surface area for contact with the joints 99, 101, which makes it possible to make up for certain inaccuracies in the positioning of the joints or uprights 2 in order to ensure adequate sealing even in case of construction or imprecise assembly of parts of the cabinet, or due to deformations related to the aging of the cabinet.

  Figures 21 and 22 show the interlocking nut 8 alone, respectively in two different positions. The nesting nut 8 has a first portion 102 of square section C side, extending by a second portion 103, also of square section C2, C2 being greater than ci. Two parallelepipedal wings 104 project from the second portion 103 in the extension of two adjacent faces of this second portion 103. Each of the wings 104 carries a hole 105 for the passage of the rivets 66 (see Figures 17 and 18). The first portion 102 is intended, as explained above, to fit into the interlocking profile 9 (see Figure 4) and has for this purpose claws 106 for a fitting force of these two parts. The second portion 103 has nicks 107 for freeing space for the positioning of the clips-nuts 6 (see Figure 2). The first portion 102 and the second portion 103 comprise an internal recess 108 which is, in the present example, cylindrical and passes right through the first portion 102 and the second portion 103. At the first portion 102, this recess 108 has smooth walls and allows the passage of the tie rod 10 (see Figure 4). At the level of the second portion 103, the recess 108 is threaded over almost the entire length of the second portion 103 to allow screwing of the tie rod 10. The second portion 103 also has claws 109 to allow fitting into the force of this second portion 103 in the upright 2. Figure 23 shows in horizontal section the assembly of the upright 2 with the interlocking section 9 and the interlocking nut 8, once these three parts have been nested in accordance with Figures 2 and 3. In a variant with respect to the amount 2 described above, the amount 2 of Figure 23 has, in section, a fourth section 75 hairpin and a ninth section 90 hairpin each having a loop more open . In addition, according to this variant, the sixth section 81 and the seventh section 84 are connected by a sharp angle instead of a rounded angle, for example thanks to a laser weld. For an optimum assembly, in the present example, the distance D1 separating the sections of the upright 2 respectively corresponding to the second section 69 and the seventh section 84, or respectively corresponding to the sixth section 81 and the first section 68, is substantially equal to the outer side the square formed by the square section of the interlocking profile 9. This distance D1 is also substantially equal to the C2 side (see FIGS. 21 and 22) of the second portion 103 of the interlocking nut 8.

  Similarly, the distance D2 separating, internally, the opposite walls of the interlocking profile 9 is substantially equal to the side C of the first portion 102 of the interlocking nut 8 (see Figures 21 and 22). Thus, these three parts can be fitted without play against each other for optimum support, or even force-fitted or held together by any known means. The tie rod 10, once tightened, keeps this assembly in place. The enlarged view of FIG. 24, corresponding to the box XXIV of FIG. 9, shows the positioning of the interlocking profile 9 within the frame 4 to allow the engagement of the upright 2 around the interlocking profile 9. space E is formed between the interlocking profile 9 and the crosspieces 3 of the frame 4 over the entire height of the interlocking profile 9 which protrudes beyond the weld 18. The interlocking of the interlocking nut 8 in the profile 9 interlocking is simultaneously with the engagement of the upright 2 on the interlocking profile 9. Figures 25 and 26 respectively show an upright 2 and a cross member 3 on which were mounted nut clips 6, 6 '. The amount 2 of Figure 25 corresponds to the variant of the amount 2 shown in Figure 23, while the cross member 3 of Figure 26 is, compared to the previous 3 cross members, a variant having, in section, a fourth section 30 in hairpin with a more open loop. On the upright of FIG. 25 and on the cross member of FIG. 26, nut clips 6 are mounted on the pan corresponding to the second section 22, 69.

  These clips-nuts 6 abut against the stop surfaces 111, 113 so that the threaded portion of the nut-clip 6 is positioned opposite the hole 23, 60. In this configuration, the end 110 of the clip-nuts 6 is engaged in the receiving space 5, 5 '.

  As a variant, with respect to FIGS. 25 and 26, the nut-and-nut clip 6 may comprise an end 110 of a height that is adapted to force fit into the receiving space 5, 5 'in order to better hold the clip-nut. 6. In FIG. 26, a second nut-clip 6 'is mounted on the side of the cross member 3 corresponding to the first section 20 while abutting against the stop surface 112 so that the threaded part of the nut-clip 6 'comes next to the hole 21 and that the end 110' of the nut-clip 6 'engages in the space defined by the bracket 52. Similarly, for the amount 2 of Figure 25, a second clip-nut (not shown) can be mounted on the side of the upright 2 corresponding to the first section 68, similarly to the nut clip 6 'of FIG. 26, the end 110' then engaging in the receiving space 5 ' . Alternative embodiments of a cabinet for electrical appliances comprising the frame described can be envisaged without departing from the scope of the invention. In particular, as illustrated in Figure 27, the amount 2 'may comprise a fifth section 78' disposed at an angle relative to the second section 69 ', while allowing the interlocking with the interlocking section 9'. Moreover, the section of the upright 2 'of FIG. 27 comprises, as a variant with respect to the uprights 2 previously described, a fourth hairpin section 75' and a ninth hairpin section 90 'both having longer branches. spaced. Alternatively also, the interlocking profile, which may be solid or hollow, and the interlocking nut may have different sections of the present example while maintaining their interlocking function. Furthermore, the holes 17 (see Figures 7, 9, 11, 12, 13 and 24) for fixing the seals 7 may be replaced or supplemented by any openings, for example oblong openings formed by a punch.
