Description

System for fixing electrical equipment to La profiles

  the present invention relates to a fastening system

  electrical equipment on profiles.

  The invention relates more particularly to a system for attaching electrical equipment to displays comprising profiles.

  transverse mounted on vertical uprights.

  It is known in the trade for displays consisting of a holder

  trays and trays. The tray holder includes a metal frame.

  Profiles are positioned horizontally and are fixed by their 1o ends to the vertical uprights of the frame. Wooden facings or wooden slats are placed between the profiles. Horizontal trays can be arranged on the front face of the tray holder. To do this, the front face of the profiles has a longitudinal groove. The trays can thus be clipped into the grooves of the profiles. These i5 displays can be used to display electrical devices. Currently, the electrical devices on display are connected to an outlet at the rear of the display. Drilled holes are made in the wooden slats to pass the connection cables of the devices

  electric. This type of connection requires machining the wooden slats.

  A second solution consists in making a cut in the slats in order to embed the electrical equipment constituting the socket or allowing for example the connection of an antenna. This second type of connection also requires machining of the wooden slats. A change of position of a connection requires the installation of another socket or a

  disassembly of the display slats.

  The present invention therefore aims to overcome the drawbacks of the prior art by proposing a fastening system for electrical equipment which is easy, quick and which allows the easy modification of the

  positioning of electrical equipment.

2 2788173

  This object is achieved by the fact that the system for fixing electrical equipment on transverse profiles mounted on vertical uprights, said profiles having a rear face and a front face, is characterized in that it comprises an equipment support. electric which can be locked in rotation and translation between two profiles by holding means, said support allowing mounting

electrical equipment.

  According to another particularity, the support comprises a plate having a central opening which makes it possible to receive the base of an appliance, the means for holding the support consist of front tabs arranged on the front face of the plate and coming in support against the front face of the profiles and rear legs arranged on the face

  rear of the plate bearing against the rear face of the profiles.

  According to another particular feature, the front and / or rear legs are

  elastic to allow the support to be clipped onto two distant profiles.

  According to another particular feature, the length of the front legs of the

  support is less than that of the hind legs or vice versa.

  Another object of the invention is to propose a second system of

  fixing of electrical equipment between two distant profiles.

  This object is achieved by the fact that the support consists of a box comprising a bottom and a vertical and circular wall or vertical walls, the holding means consisting of perpendicular legs and integral with the vertical wall of said box and coming resting on the front face of the profiles, and of elastic clip tabs formed in the wall (s), coming to be clipped against the wall

rear of the profiles.

  According to another particularity, the electrical apparatus positioned on

  the support allows the tabs to be locked.

3 2788173

  According to another particularity, the locking is obtained by pinching a tab formed at the end of the tongues between the switchgear base and

the walls of the profiles.

  According to another particular feature, the tabs of the tongues protrude relative to the front walls of the profiles to allow a

  manual unlocking of the tabs from the front of the profiles.

  According to another particularity, the support of the first or of the second fixing system is mounted on the transverse profiles of a display, said display comprising a frame on the vertical uprights from which the profiles are mounted, horizontal plates and mounted slats. between the profiles so that the electrical equipment is positioned between two profiles and between two slats mounted on the same two profiles, the front face of the profiles having a groove allowing the mounting of said plates. According to another particular feature, the covering cover of the electrical equipment abuts against flanges arranged on the side

  and on the other side of the groove of each profile.

  According to another particular feature, the upper face of the covering cover, the plane passing through the end of the edges of the profiles, thus

  that the front face of the slats are substantially combined.

  Other features and advantages of the present invention

  Figure 2 shows an example of a display of the prior art.

  The display unit includes a tray holder (1) on which trays (5) can be assembled. The tray holder (2) consists of a frame (2), for example metallic, and profiles (3) which can be mounted at their ends to the vertical uprights of the frame (2). The profiles are parallel to each other, being regularly distributed along the vertical uprights of the frame. Slats (4), for example made of wood, are assembled between the profiles (3). A single slat or several slats of smaller dimensions can be inserted between two profiles. The front wall of the profiles has a groove which allows the mounting of plates (5) provided with lugs. According to a first type of display, the profiles are assembled to

2788173

  vertical uprights. The slats are slid between two profiles by one of their ends. Access to the ends of the profiles is obtained by dismantling one of the vertical uprights. According to a second type of display, the profiles are slid between the two vertical uprights of the frame by removing the upper upright from the frame. Thus, to make the display, a profile and a slat are successively stacked from above

  between the vertical uprights of the frame. In order to simplify the description of

  the invention, only the first type of display defined above is used

  as an example in the description.

  FIG. 3 represents two remote sections usable according to the invention. These two sections are assembled on the vertical uprights of the display previously described by way of example. A first profile (6) is arranged on the frame of the display above and parallel to a second profile (7). The profiles (6,7) have, in cross section, a rectangular parallelepiped shape, and have an upper wall (8a, 8b), a lower wall (9a, 9b) a front wall (10) and a rear wall (11) . A longitudinal central wall (12) connects the upper face (8a) and the lower face (9a). This central wall (12) is parallel to the front (10) and rear (11) walls. The front wall (10) has a longitudinal opening defining a lower front part or wall (13a) and an upper front part or wall (14a). The free end of the lower front part (13a), respectively the upper front part (14a), has respectively a lower rim (15), respectively an upper rim (16). These ledges

  are perpendicular to the front wall (10) and are directed outwards.

  A slat (17) is positioned between the two sections (6, 7). The slat (17) is parallelepiped. It has a front main face (18), a rear main face (19), an upper edge (20) and a lower edge (21). Each edge (20, 21) has, for example, a longitudinal groove (22). The width of these grooves (22) is substantially equal to the width of the lower (9a, 9b) and upper (8a, 8b) walls of the profiles (6, 7). The depth of the grooves is less than or equal to the height of the

6 2788173

  lower (13a, 13b) and upper (14a, 14b) front sections of the profiles.

  The slats (17) can thus be slid between two sections (6, 7) by one of their ends. To gain access to the ends of the profiles and install the slats, one of the vertical uprights of the frame can be removed. The front face (18) of the slat is substantially in the same plane as the free edges of the lower (15) and upper (16) edges of the profiles. Other systems can be provided for the installation of the slats between the profiles. The rear main face (19) of the slats can be substantially in the same plane as the rear wall (11) of the profiles and have movable fixing means which can come to bear against the rear wall (11). The installation of this type of slats then does not require

  for dismantling the vertical uprights of the frame.

  Figure 1 shows a first embodiment of support

  (24) for electrical equipment which can be assembled between two profiles.

  The support (24) consists of a rectangular plate (25) having in its middle an opening (26), for example circular. A box, not shown in Figure 1, consisting of a bottom and vertical walls, can be arranged on the rear face of the plate so that the opening (26) of the plate (25) opens onto the inside the box. The plate (25) has an upper side (28), a lower side (29) and two lateral sides (30, 31). The plate (25) has holes (27), in which screws,

  allowing the attachment of electrical equipment, can be screwed.

  Depending on the thickness of the plate (25), the rear face of the plate may include screw wells arranged in the extension of the holes (27). The front face (32) of the plate has a set of

  so-called "front" legs which project from the upper (28) and lower (29) sides.

  For example, two upper front legs (33b), respectively rear (33a), protrude from the ends of the upper side (28), respectively lower (29), of the plate (25). Similarly, the rear face (34) comprises so-called "rear" legs (35a, 35b), arranged symmetrically with respect to the front legs (33a, 33b). The distance between

7 2788173

  a front leg and a rear leg opposite is substantially equal to the

  width of the lower (9a, 9b) and upper (8a, 8b) walls of the profiles.

  The support can thus be slid by the ends of a first (6) and second profiles (7). The upper front legs (33b), respectively lower (33a), bear against the lower front part (13a) of the first profile (6), respectively against the upper front part (14b) of the second profile (7). The upper rear legs (35b), respectively lower (35a), bear against the rear wall of the first profile, respectively of the second profile. The support (24) can be positioned between two sections and between two wooden slats mounted between the same two sections at the desired location. In order to install the support on a display (1) provided with slats as shown in Figure 2, two cuts can be made on a slat between two profiles to form two

  slat portions between which the support will be positioned.

  The support (24) thus positioned makes it possible to fix electrical equipment. FIGS. 4 and 5 show an example of a base (36) and a covering cover (37) of an electrical apparatus, which can be fixed on the support (24) described above. The base (36) and the covering cover (37) shown in Figures 4 and 5 are two examples of elements for forming a socket. The base and the cover each consist of a plate (38, 39), for example, of rectangular shape, comprising in the middle a recess (40, 41) of circular shape so that the cover (37) can be fit onto the base (36). The bottom (42) of the recess (40) of the base (36) may include housings provided for receiving different components allowing the connection of the socket to the electrical network. The bottom (43) of the recess (41) of the cover has different holes, ages. Two holes, ages (44) are provided for the insertion of the plugs of an electrical appliance. A third hole, age (45) allows the passage of the earth plug. The cover can be attached to the base by means of a screw. A fourth

8 2788173

  drilling (46) allows the passage of a screw which can be screwed into a well

  (47) for screwing present in the recess of the base.

  The diameter of the circular recess (40) of the base is less than or equal to the circular opening (26) of the support (24). The base can thus be fitted onto the support. The plate (38) constituting the base has openings (48) in a circular sector. Screws are partially screwed into the holes (27) of the support. In known manner, the base can snap onto the head of the screws through the openings (48), one of the ends of which has a diameter greater than the head of the screws, while the 0o opening sector has a width less than the head of the screw. The screws are then screwed to secure the base to the support. When the plug connection is made, the cover can then be screwed onto the base. The dimensions of the plate constituting the cover can be provided so that the upper edge, respectively lower, of said i5 plate is in contact with or near the lower edge (15) of the first

  profile (6), respectively of the upper edge (16) of the second profile (7).

  The outer surface of the plate constituting the cover may be substantially in the plane than the front face of the slats, and / or that

  passing through the ends of the flanges (15, 16) of the profiles.

  According to a variant of the first embodiment, the front (33a, 33b) and rear (35a, 35b) legs are elastic and allow the support (24) to be clipped directly between two sections (6, 7). This embodiment makes it possible to install the support quickly without prior disassembly of the vertical uprights of the frame. To facilitate clipping, the length of the front legs (33a, 33b) is less than that of the rear legs (35a, 35b) or vice versa.

  A description of a second embodiment of a support will

  now be made with reference to Figures 6a and 6b. The support (50) for electrical equipment consists of a box (51), for example of circular shape, which may include a bottom (52) and a vertical wall

9 2788173

  circular. The wall can be flattened on two diametrically opposite portions. The wall then consists of two circular parts (53a, 53b) connected to each other by two flat parts (54a, 54b). A cutout (55) is formed on all or part of each junction line between the flat parts and the circular parts in order to form two tongues

  elastic, hereinafter called "lower tab" (57) and "upper" (56).

  The outer face of the tongues has a lug (58). Each lug (58) has a flat surface (66) substantially perpendicular to the tongue and oriented in the opposite direction to the bottom (52) of the box. Each circular part has a rim (59, 60) directed perpendicularly to the outside. The upper end (61), respectively lower (62), of the flanges is substantially in the same plane as the outer surface of the upper tongue (56), respectively lower (57). Legs are arranged on the edges of the circular parts. Each rim comprises, for example, an upper tab (63), respectively lower (64), projecting from the upper end (61), respectively lower (62),

of said ledge.

  The distance between the outer faces of the tongues (56, 57) is substantially equal to the separation distance between two sections (6, 7). The distance between the upper legs (63), respectively lower (64), and the plane passing through the flat surface (66) of the lug (58) of the upper tongue, respectively lower, is substantially equal to the width of the walls lower (9a, 9b) and upper (8a, 8b) of

  profiles (6, 7). The support (50) can thus be clipped onto two distant sections.

  According to Figure 7, the support can be inserted between the bottom wall (9a)

  of the first profile (6) and the upper wall (8b) of the second profile (7).

  During this insertion operation, the pins (58) being in contact with

  said walls (9a, 8b), the tongues (56, 57) elastically deform.

  The support (50) is inserted between the two profiles (6, 7) until the lower, respectively upper, tabs of the support come into abutment against the front lower part (13a) of the first profile (6),

2788173

  respectively the upper front part (14b) of the second profile (7), as shown in FIG. 8a. The lugs (58) snap against the rear wall (11) of the profiles, the flat surfaces (66) of the lugs (58) being in contact with the outer surface of the rear walls (11). The support (50) can be removed by exerting pressure on the pins when they are accessible from the rear face of the display. The support can also be removed from the front side by moving the tabs (56, 57) inwards, one after the other, using a tool such as a screwdriver for example. The screwdriver is inserted between the tongue (56), io respectively (57), and the wall (9a), respectively (8a) of the profile (6), respectively (7), in order to disengage the lug (58) from the tongue of the

rear wall (11) of the profile.

  An appliance base (36), similar to that described above, can be fixed by means of screws on the support. Screwing wells (67, FIG. 6a) are arranged against the inner surface of the circular parts (53a, 53b) of the support (50). The system for fixing the base to the support can be identical to that described above. The dimensions of the plate (38) constituting the base are provided so that said plate comes to press against the interior surface of the tongues (56, 57), when the base is positioned on the support. The tabs (57, 56) are pinched between the

  plate (38) constituting the base and the walls (9a, 8b) of the profiles (6, 7).

  According to FIG. 8b, the end of each tongue may comprise a tab (72) arranged in the extension of the external surface of the tongue, and possibly forming a shoulder (71) oriented inwards with the rest of the tongue. The tabs (72) have a thickness provided to allow them to be pinched between the plate (38) constituting the base and the profiles (6, 7). The tabs (72) of the tongues protrude from the flanges (59, 60; FIG. 6a) of the circular parts of the support (50) so that the plate (38) constituting the base (36) rests on the flanges ( 59, 60) of each circular part of the support (50), without being in contact with the shoulder (71) of the tongues. Any elastic deformation of the tongues being prevented, the lugs are kept engaged against the rear walls (11) of the profiles. With reference to FIG. 9, a covering cover (37) can then be fixed to the base (36) by means of a screw (70) passing through a hole (46) in the covering cover (37) and being screwed into the screwing well (47) of the base (36). A space (70, Figure 8a) between the tabs (63, 64) and the flanges (15, 16) of the profiles, can be provided to accommodate the flanges (69, Figure 5) of the plate (39) constituting the cover covering (37). The tabs (72) of the tongues (56, 57) can be long enough to project relative to the lower (13a, FIG. 8b) and upper (14b) front walls of the profiles (6, 7). Thus, to remove the support, the tongues can thus be moved towards one another by manually exerting pressure on the projecting parts of the tabs of the tongues, in order to disengage the lugs from the rear walls of the profiles. The support is easily removed,

  from the front of the profiles, without requiring the use of a tool.

  Any type of display, comprising transverse profiles, can be fitted with an electrical equipment fixing system according to the invention, in particular the second type of display defined above o the profiles and the slats are stacked from above between two uprights vertical. It is clear that other modifications within the reach of man of the

  trade fall within the scope of the invention.
