Description

APPARATUS SUPPORT COMPRISING A GRIPPER ACCESSORY FOR MOUNTING TO A WALLBOX, ACCESSORY FOR GRIFFING, GRIFFING ASSEMBLY AND APPARATUS

ELECTRIC ASSOCIATED TECHNICAL FIELD TO WHICH THE INVENTION RELATES

The present invention relates to an electrical equipment support comprising a frame surrounding a receiving opening of an equipment mechanism, and, for its attachment to a wall box, at least one scratching accessory which extends perpendicularly to this device. frame, said clawing accessory comprising at least one claw base and a claw attachment mounted on the claw base, pivotally movable between a retracted position and an extended position relative to said claw base.

It also relates to an associated clawing accessory, an associated clawing assembly and electrical equipment comprising such an equipment support.

BACKGROUND

Recessed electrical apparatus generally comprises a frame-shaped apparatus support adapted to receive, in its central opening, an apparatus mechanism.

This equipment support usually comprises means for securing to a wall box recessed in a recess wall, which intervene in diametrically opposite position on the frame.

It may for example be simple holes specific to the passage of screws or even clawing accessories having claws fixing, which, under the control of claw screws, are adapted to come to anchor in the side wall of the wall box.

For example, EP2385598 discloses an apparatus support as defined in the introduction.

The claw attachment of such an equipment support is adapted to hang at a predefined depth of the wall box.

Document EP1944846 also discloses a wall box that can accommodate switch-type electrical equipment. For attachment in a wall, it comprises a scribing accessory with an actuating element and a claw that come from formation, connected by a link. The claw is here movable in translation relative to the box and the actuating element. It is not suggested that it could allow the box to hang at different depths of the wall.

However, this wall box can be positioned more or less far from the wall wall on which rests the frame of the equipment support. It is then necessary to have fixing claws of different lengths for fixing the equipment support in the wall box.

This has the disadvantage of causing the manufacture and referencing of different types of fastening claws and / or equipment support.

One possible solution to this problem lies in the use of claw extensions that attach to the base claw in order to increase its length. Such an extension claw is for example known from FR2796774. The equipment support provided with a fixing claw having a given length can then be hung in the wall box, this box wall is positioned near the frame of the equipment support, using it at its initial length, or that this wall box is positioned farther from this frame, using the claw provided with the extension of claw.

Such a solution is however complex to implement because it involves the establishment of this extension of claw that can be tricky.

Another solution is to provide two abutment surfaces for the claw, so that it can be positioned at different heights on the claw base and can therefore be hooked into a wall box more or less sunk into the wall wall.

However, the arrangement of two abutment surfaces accessible to the claw is difficult to achieve given the constraints of space of the accessory. As a result, at least one of these two surfaces has a reduced extent such that the abutment of the claw on this surface is less effective. This results in a certain fragility of the whole.

OBJECT OF THE INVENTION

In order to overcome the above-mentioned drawbacks of the state of the art, the present invention proposes a new equipment support in which a scribing accessory makes it possible to attach the equipment support to a wall box located at different depths behind this support. in a simple, fast and economical way. More particularly, according to the invention, there is provided an apparatus support as defined in the introduction, in which the equipment support comprises rack-and-pinion mounting means which cooperate with complementary mounting means belonging to the claw base, so that that the claw base is adapted to be mounted on the equipment support at at least two different heights relative to the frame of this support.

Thus, the fixing claw is itself mounted on the equipment support at at least two different heights relative to the frame of the support.

The frame 510; 610 of this equipment support 500; 600 is more particularly made of metal.

In order to receive the base of the fitting mechanism, the frame 510; 610 comprises reception means, in particular here latching means adapted to cooperate with complementary means of the base. These latching means comprise for example windows 514, 515; 614, 615 arranged in frame 510; 610 or in a falling wall surrounding the inner peripheral edge of this frame 510; 610 (Figures 9, 10, 1 1, 12 and 14) and adapted to cooperate with the complementary means of the base.

Whatever the embodiment of the equipment support envisaged, the frame 1 10; 410; 510; 610 may also include means for clipping a trim plate (not shown) and possibly a trim (not shown) on this equipment support 100; 400; 500; 600.

As can be seen in Figures 1, 2, 5, 6, 7, 9, 10, 11, 12 and 14, the apparatus support 100; 400; 500; 600 further comprises first and second securing means 130, 140; 430, 440; 530, 540; 630, 640 suitable for attachment to the wall box 700. The first securing means 130; 430; 530; 630 comprise, in at least two opposite branches of the frame 1 10; 410; 510; 610, a keyhole-shaped bore 1 18; 418; 518; 618 which allows the passage of the threaded body of a fixing screw 710 (Figure 1 1) intended to be screwed into a screwing well 720 corresponding to the wall box 700.

The second securing means 140; 440; 540; 640 comprise, at the rear of two opposite branches of the frame 1 10; 410; 510; 610, two scribing accessories 200 according to the invention.

They also comprise two reception elements 142; 442; 542; 642 (Figures 1, 5, 6, 7, 12 and 14) which extend perpendicular to the rear face of the frame 1 10; 410; 510; 610, from this rear face, and each delimit a lateral housing 141; 441; 541; 641 (FIGS. 1, 7, 12 and 14) intended to receive said scribing accessory 200.

In the case of the first and second embodiments of the equipment support 100; 400, said receiving elements 142; 442 are integrated in the side wall of the base 120; 420. They come from training with the framework of the support apparatus.

In the first embodiment, each receiving element 142 (FIG. 1) comprises a portion of the lateral wall of the base 120, which forms the bottom of the lateral housing 141. The receiving element 142 also comprises two wings 144 (FIG. 1) extending perpendicularly to the frame 1 10, arranged projecting from the side wall of the base 120 and forming the sides of this lateral housing 141.

The lateral housing 141 is partially closed, at the front end, by the frame 1 10 of the equipment support. It opens at the front on a through opening 1 14 (Figures 1 and 2) of this frame 1 10, and is open at the rear end. This through opening 1 14 here has a quasi-circular section.

The apparatus support 100 further comprises, in the case of this first embodiment, an intermediate element 300 (FIGS. 1 to 4) separated from the frame 1 10 of the equipment support and adapted to be attached to a receiving part of the equipment support formed here by the receiving element 142.

This intermediate element 300 has a parallelepipedal shape elongate along a longitudinal axis A1. It is more particularly represented in FIG. This intermediate element 300 has in particular two main faces 312, 313 whose inner face 313 is arranged to be attached against the bottom 143 of the lateral housing 141 delimited by the receiving element 142 of the equipment support 100, and one side of which The outer side 312 is intended to be turned facing the side wall of the wall box 700 (see Figures 1 and 3).

The two inner and outer faces 312; 313 are connected by a front end face 314 and two side faces 315 (Figure 3).

The intermediate element 300 further comprises fixing means allowing the installer to fix it rigidly in the corresponding lateral housing 141 of the equipment support 100.

These mounting means are here latching means, which allows to assemble and dismount at will the intermediate element 300 of the equipment support 100, as the first or second securing means 130, 140 are used to fix the equipment support 100 to the wall box 700.

As shown in Figures 1 and 3, these mounting means comprise in particular two lugs 31 1A which rise parallel to the longitudinal axis A1 of the intermediate member 300 from the front end face 314 of the intermediate element 300. The longitudinal axis A1 of this intermediate element extends perpendicularly to the frame 1 10 of the equipment support 100 when the intermediate element 300 is fixed on it.

The lugs 31 1 A are adapted to engage in corresponding openings (not visible in the figures) provided in the branches of the frame 1 10 of the equipment support 100.

The fixing means of the intermediate element 300 also comprise two ratchet teeth 31 1 B which are in the form of ribs extending parallel to the longitudinal axis A1, from each lateral face 315, and which are adapted to attach to grooves provided in correspondence in the wings 144 of the lateral housing 141 of the receiving element 142 of the equipment support 100.

These fixing means finally comprise two studs 31 1 C which extend perpendicularly to the axis A1 from the lateral faces of the intermediate element 300 and which are arranged to be housed in cavities (not visible in the figures) provided in hollow correspondence in the wings 144 of the lateral housing 141 of the equipment support 100. These two pads 31 1 C allow, once the intermediate element 300 is snapped into its lateral housing 141, to block rigidly any movement of this intermediate element 300 relative to the equipment support 100 along the longitudinal axis A1.

This intermediate element 300 further has, in hollow of its outer face 313, a receiving housing 316 for accommodating the claw accessory 200 (Figures 1 and 3).

This reception housing 316 is delimited by a bottom parallel to the inner face 313 of the intermediate element 300, two inner lateral faces 318 (FIG. 3) extending parallel to the longitudinal axis A1 of the intermediate element 300 and a front end face perpendicular to said bottom and to the longitudinal axis A1. It is however open on the side of the rear end opposite the front end of this intermediate element 300.

In the case of the second embodiment, shown in FIGS. 5 to 8, each receiving element 442 of the equipment support 400 comprises a portion of the lateral wall of the base 420, which forms the bottom 443 of the lateral housing 441 and two 444 opposite side wings, formed projecting from the side wall of the base 420 and which form the sides of the lateral housing 441 (Figures 5, 6 and 7). The lateral wings 444 extend parallel to a longitudinal axis A3 of the receiving element 442 perpendicular to the frame 410 of the equipment support (FIGS. 5, 6 and 7).

The receiving element 442 here comes entirely from formation with the base 420 intended to receive the fitting mechanism.

The lateral housing 441 is partially closed, at the front end, by the frame 410 of the equipment support. It opens, at the front, on a through opening 414 of this frame 410, and is open at the rear end (Figure 7). The through opening 414 here has a wide rectangular section facilitating demolding of the equipment support 400.

In the case of the third and fourth embodiments of the equipment support 500; 600, shown in Figures 9 to 15, the receiving member 542; 642 includes a tab 543; 643 forming the bottom of the lateral housing 541; 641 and two lateral wings 544; 644 forming the sides of this lateral housing 541; 641. This tab 543; 643 and these lateral wings 544; 644 extend along a longitudinal axis A4; A5 of the receiving element 542; 642 perpendicular to the frame 510; 610 of the equipment support 500; 600 (Figures 12 and 14).

This tab 543; 643 and these lateral wings 544; 644 are preferably formed by cutting and folding a portion of the metal plate also forming the frame 510; 610.

The lateral housing 541; 641 is partially closed at the front end by the frame 510; 610 of the equipment support. It opens at the front on a through opening formed by one of the windows 514; 614 (Figures 1 and 2) of this frame 1 10, and is open at the rear end.

As shown in FIGS. 1, 2, 5, 6, 9, 10, 1 1, 16, 17 and 19 to 22, the dogging accessory 200 includes a claw base 210, a claw 220 for attachment pivotally mounted on the claw base 210 and a control screw engaged through an opening 223 (FIG. 17) provided in this claw 220.

The claw 220 is here separate from the claw base 210. It constitutes a separate part of the claw base 210, attached thereto by means of the control screw, as will be explained in more detail later.

The clawing accessory 200 finally comprises a nut 240 screwed onto the control screw 230 after the opening 223 of the claw 220 has been engaged on the control screw 230. This nut makes it possible, when an installer screws the screw of control 230, to tilt the claw 220 so that it clings to the side wall of the wall box 700 (Figures 16 and 17). The control screw 230 and the nut 240 are in fact arranged such that the screwing of the screw in the nut causes the passage of said claw 220 from its retracted position to its deployed position.

This scribing accessory 200 is here adapted to cooperate with all the embodiments of the equipment support 100; 400; 500; 600.

The claw base 210 generally has a parallelepipedal shape and has an inner face 212 intended to be applied either against the bottom of the receiving housing 316 of the intermediate element 300, in the case of the first embodiment, or directly against the background 443; 543; 643 of the lateral housing 441, 541, 641 delimited by the receiving element 442; 542; 642 of the equipment support 400; 500; 600, in the case of the second, third and fourth embodiments.

The claw base 210 further comprises an outer face 21 1 opposite to the inner face 212, two opposite lateral faces 213 and a rear face 214 opposite to a front face 215.

A receiving well 216 passes through the claw base 210 and opens on both sides on the front 215 and rear 214 faces of the claw base 210 to accommodate said control screw 230. This receiving well 216 is cylindrical and has a A2 common longitudinal axis with that of the control screw 230 when it is housed inside (Figures 16 and 17).

In addition, the longitudinal axis A2 of the receiving well 216 of the claw base 210 coincides with the longitudinal axis A1 of the intermediate element 300 when the clawing accessory 200 is received in this intermediate element 300, in the case of the first embodiment, and coincides with the longitudinal axis A3; A4; A5 of the receiving element 442; 542; 642 in the case of the second, third and fourth embodiments.

As shown more particularly in Figures 16 and 17, the fixing claw 220 has a generally U-shaped configuration, with a main wall 221 and two side jambs.

Said main wall 221 is rectangular and flat, it comprises in its middle part the opening 223. The two lateral jambs form two parallel fastening tabs 224 of axes X1 (FIGS. 16 and 17) which extend from the ends of the main wall 221. The free ends of these two attachment tabs 224 each have, on their outer edge intended to be turned towards the side wall of the wall box, a pointed tooth 225 adapted to hook to this side wall.

This claw attachment is derived from an operation of cutting and folding a raw metal strip. It is inexpensive to manufacture.

The claw 220 is movably mounted on the claw base 210 to swing about a pivot axis orthogonal to the longitudinal axis A2 of the well 216 of the claw base 210, between a retracted position (FIGS. 2, 5, 6, 9). , 10, 1 1, 19 and 21) in which the hooking tabs 224 of the claw extend in the extension of the claw base 210, in a mean plane parallel to the outer faces 21 1 and inner 212 of the claw base. 210 and a deployed position (Figures 20 and 22), inclined relative to the retracted position, in which it projects relative to the outer face 21 1 of the claw base 210.

Thus, in the retracted position, the axis X1 of the hooking tabs 224 of the claw extends parallel to the longitudinal axis A2 of the receiving well 216 of the claw base 210, while in the deployed position, the axis X1 of the hook tabs 224 of the claw 220 is inclined with respect to the longitudinal axis A2 of the receiving well 216 of the claw base 210 so that the teeth 225 of this claw 220 can cling to the side wall from the wall box 700.

The lateral jambs forming the hooking tabs 224 remain parallel to the opposite lateral faces 213 of the claw base 210.

Said opposite side faces 213 of the claw base 210 extend perpendicular to a pivot axis of the claw 220.

The control screw 230 is a conventional and inexpensive screw, as can be found in the trade.

It has a maneuvering head 231 with a recess here cruciform, and a threaded body 232 (Figure 17).

As shown in particular in Figures 19 to 22, the control screw 230 is engaged in the well 216 through the claw base 210. The front face 215 of the claw base 210 thus forms a support for the control head 231 of the control screw 230.

The operating head 231 of the control screw 230 is accessible to the installer through the through opening 1 14; 414; 514; 614 (Figures 1, 2, 7, 9 to 12 and 14) on which opens the lateral housing 141; 441; 541; 641 in box 1 10; 410; 510; 610 of the apparatus support 100; 400; 500; 600, when the scribing accessory 200 is mounted thereon.

In addition, in the case of the first embodiment, when the scribing accessory 200 is received in the intermediate member 300, the head 231 of the control screw 230 of the scribing accessory 200 is accessible through a well. access 317 of this intermediate element 300 (Figures 1 and 3) which extends along the longitudinal axis A1 of this intermediate element and opens on one side on the front face 314 of the intermediate element, between the lugs 31 1A, and, on the other side, in the receiving housing 316, facing the head 231 of the control screw 230.

The control screw 230 is mounted free to rotate in the well of receiving 216 of the claw base 210.

It passes through the opening 223 provided in the main wall 221 of the claw and the nut 240 which is located on the side of its free end.

The nut 240 here has a substantially parallelepiped shape. This nut 240 is traversed by a threaded well 241 (Figure 17) with which the threaded body 232 of the control screw is engaged. It is guided in translation along the axis of the receiving well 216 of the claw base 210 by the control screw 230.

It is also guided by the bottom of the receiving housing 316 of the intermediate element 300 in the case of the first embodiment, or by the bottom 443; 543; 643 of the lateral housing 441; 541; 641 delimited by the receiving element 442; 542; 642 of the equipment support 400; 500; 600 in the other embodiments.

It is also guided along the hooking tabs 224 of the claw 220 which extend at a distance from each other equal, within play, to the width of the nut 240.

As shown in particular in Figure 17, the parallel axes X1 of the hooking tabs 224 of the claw 220 are inclined relative to the plane of the main wall 221 of the claw.

The nut 240 has meanwhile a plane upper face perpendicular to the longitudinal axis A2 of the receiving well 216 of the claw base.
