Description

Technical Field

[0001] The present invention generally relates to floor sockets for electrical and / or electronic equipment.

[0002] The floor socket is installed in the opening of the raised floor or in a recessed box fixed to the poured surface, thereby forming a reserved space for installing various equipment.

[0003] Advantageously, floor sockets are used to equip the floor of a multi-station office space, such as an open office space, a meeting or conference hall or even an exhibition room, so as to provide power sockets, data interface sockets and telephone sockets as close as possible to each station, which sockets are respectively attached to the power transmission network, computer network and telephone network of this space.

[0004] The present invention specifically relates to a floor socket, which comprises a side wall, the side wall comprising a front edge and two opposite parts with two grooves, each groove having a rotating part, which forms a support for receiving the shaft neck of a cover plate, the cooperation between the two shaft necks of the cover plate and the two rotating parts of the groove enables the cover plate to pivot on the side wall, at least one of the grooves comprises a guide part, which is different from (different from, separated from) the rotating part and extends at least partially parallel to the front edge.

[0005] The guide portion facilitates the seating or extraction of the corresponding journal of the cover plate in the rotating portion of the groove. Background Art

[0006] A floor socket as described above is known from document EP1811624, wherein the guide portion of the groove is completely parallel to the front edge of the side wall of the floor socket and is directly attached to the rotating portion of the groove. According to the document, the rotating portion is an arc-shaped portion. The arc-shaped lower edge of the rotating portion (farthest from the front edge of the side wall of the floor socket) is directly attached to the lower edge of the guide portion, while the guide portion extends parallel to the front edge of the side wall; and the arc-shaped upper edge of the rotating portion (closest to the front edge of the side wall of the floor socket) includes an extension portion at its end on one side of the guide portion, which extends toward the front edge of the side wall of the floor socket. This extension portion is attached to the upper edge of the guide portion extending parallel to the front edge of the side wall of the floor socket. This extension portion allows the cover plate to be opened at 90 degrees relative to the front edge of the side wall of the floor socket.

[0007] The main disadvantage of this arrangement is that, during use, when the cover is pivoted on the side wall to open or close the floor socket, the journals of the cover may become inserted into the guide portions of the grooves, causing the cover to be accidentally removed. Summary of the invention

[0008] To remedy this shortcoming, the present invention proposes a floor socket that is easy to manufacture, wherein the hinged arrangement of the cover plate on the side wall can prevent the cover plate from being accidentally removed.

[0009] More specifically, according to the present invention, a floor socket as described in the technical field section is proposed, wherein the groove includes a joining portion in the shape of a tortuous channel (chicane) between the rotating part and the guide part, the joining portion having an L-shaped or stepped profile and having a stop edge facing the rotating part, the stop edge extending in a direction perpendicular to the front edge over a distance (spacing) greater than the height of the journal, and attached to the edge of the guide portion by a circular edge for the journal to pass over.

[0010] Thanks to the invention, when the cover is pivoted on the side wall of the floor socket, the corresponding journal of the cover is maintained in the rotating part of the groove by the stop edge of the engagement portion. Thanks to the stop edge, this journal can no longer be inserted uncontrolled into the guide portion of this groove. The removal of the cover is therefore dependent on an operation by the user, who must translate the cover perpendicularly to the front edge of the side wall so that the journal passes over the stop edge of the engagement portion and is inserted into the guide portion of the groove.

[0011] Other features of the floor socket according to the present invention are as follows:

[0012] - the engagement portion comprises a first end section extending on the same side as the stop edge and communicating with the guide portion, and a second end section distinct from the first end section, facing the stop edge and communicating with the rotation portion;

[0013] - the guide portion comprises a horizontal portion extending along an axis parallel to the front edge and an inclined portion extending from the horizontal portion in the direction of the front edge along an axis inclined relative to the front edge, the inclined portion opening into the first end section of the engagement portion;

[0014] - the engagement portion is delimited by a horizontal edge parallel to the front edge of the side wall and by a vertical edge perpendicular to the front edge, the vertical edge forming the stop edge, the horizontal edge extending above the circular edge;

[0015] - the width of the guide part, the engagement part and the rotation part of the groove corresponds to the height of the journal within the clearance allowable range;

[0016] - the rotational parts of the two grooves are arc-shaped parts;

[0017] - the two grooves of the side wall are different, one of these grooves comprising only a rotation part;

[0018] - a groove is formed with the side wall and is opened on two opposite surfaces of the side wall;

[0019] - the groove comprises the rotating part and the guide part connected by the engagement part, the groove being formed by a part of the side wall and an insert made of synthetic material attached to the side wall so that the groove has a bottom formed by a part of the side wall;

[0020] - the groove comprises a rotating portion and a guide portion connected by the engaging portion, the groove comprises a bottom wall formed by a portion of the side wall so that the groove does not open outside the floor socket, the groove being molded together with the side wall as a single component.

[0037] In the following description, the terms "front" and "rear" are defined relative to the user's line of sight, with the front elements of the floor socket facing the user and the rear elements facing away from the user. Similarly, the terms "interior" or "inner side" refer to elements facing toward the center of the floor socket, and "exterior" or "outer side" refer to elements facing away from this center.

[0038] exist Figure 1 In FIG. 1 , a preferred embodiment of a floor socket 1 is shown in schematic form, which is positioned in an opening in a receiving floor.

[0039] More specifically, the floor socket 1 is intended to be fixed in an opening of a raised floor, usually made of wood, or in a recessed box in a cast surface. It is used to accommodate an electrical connection module not shown here.

[0040] The floor socket 1 includes a side wall 10, and a support 20 is attached to the inside of the side wall 10 for mounting various connection modules. In front of the side wall 10, the floor socket 1 includes a cover plate 30 pivotally mounted on the side wall 10, thereby closing the front opening of the floor socket 1. Behind the side wall 10, mounting devices 40, 50 are provided so that the floor socket 1 can be against the cast surface layer (building waterproof surface layer) and hooked to the embedded box of the elevated floor or the cast surface layer.

[0041] All the different elements of the floor socket 1 described above (side walls, mounting support, cover plate and mounting device) are usually made of metal material.

[0042] The side wall 10 is made of an element obtained by cutting, folding and assembling a metal sheet. Here, it comprises four panels 10A, 10B, which are parallel in pairs, thereby forming a square or rectangular frame.

[0043] In another embodiment not shown, it is conceivable that the side walls are cylindrical walls, forming an annular frame.

[0044] The side wall 10 has a circumferential front edge 11 which delimits a front opening 11A of the floor socket 1 in a plane P, and an opposite circumferential rear edge 12 which is bounded on the inside of the side wall 10 by a boss 13 which extends in a plane parallel to said plane P and delimits a rear opening 12A opposite the front opening 11A.

[0045] Here, the floor socket 1 is a box body for seamless installation on the front surface of the receiving floor, and the front edge 11 of the side wall 10 is a straight edge without an external flange. This front edge 11 is intended to be along the edge of the receiving floor opening without exceeding the receiving floor opening.

[0046] This will be explained later. Figures 10 to 14 In the variant shown, the floor socket 1 ′ comprises a side wall 10 ′ along the front edge 11 ′ of which there is an external flange 18 ′A, which is intended to come into contact with the front surface of the floor around the receiving opening.

[0047] like Figure 1As shown, the boss 13 of the side wall 10 includes four circular through holes 14, which are arranged at the four inner corners of the side wall 10. On each of the two parallel panels 10B of the side wall 10, two windows 15 are arranged, which are spaced apart along the length direction of the panel 10B. Each rectangular window 15 is defined by three edges, and the fourth edge is opened on the rear edge 12 of the side wall 10. The window 15 extends through the groove formed in the boss 13. In addition, on the inner surface of the above-mentioned two parallel panels 10B, two U-shaped profiles 16 are arranged, which have a bottom and two parallel longitudinal side wings 17, 18. Each profile 16 is fixed on the panel 10B so that the side wing 18 abuts against the boss 13, and the bottom of the profile 16 extends parallel to the inner surface of the panel 10B. Between each profile 16 and each panel 10B, a cavity is defined that opens to the outside of the side wall 10 through the window 15. The side wings 17, 18 of each molding 16 include grooves 17A, 18A. The groove 18A of the side wing 18 abuts against the boss 13 and overlaps with the groove of the boss 13. The groove 17A of the other side wing 17 opens the cavity to the front opening 11A of the floor socket 1 and faces the window 15.

[0048] The mounting means 40 , 50 of the floor socket 1 comprise four feet 40 intended to rest against the poured surface, and four claw screw systems 50 intended to hook onto the rear edge of the raised floor or of the recessed box.

[0049] Each leg 40 comprises a base plate 42 (here with a circular outer profile) capable of resting against the cast surface, and comprises a threaded body 41 rising perpendicularly thereto from the base plate 42. The lower end of each threaded body 41 is inserted into the base plate 42 and can rotate around its longitudinal axis. At the free end opposite to the base plate 42, the threaded body comprises a notch for accommodating the tip of a tightening tool. Each threaded body 41 is associated with an internally threaded sleeve 43. Each sleeve 43 comprises an external flange at its end.

[0050] More specifically, if Figure 2 As shown, four sleeves 43 are inserted through four circular openings 14 of the boss 13 of the side wall 10, and the flange of the sleeve 43 is crimped to the boss 13 so that the sleeve 43 fixed to the side wall 10 protrudes from the rear edge 12 of the side wall 10 and extends toward the rear. The threaded body 41 of each leg 40 is screwed into each sleeve 43, thereby firmly connecting the leg 40 to the side wall 10. The position of the side wall 10 relative to the bottom plate 42 of the leg 40 is adjusted by means of a tightening tool, the tip of which is inserted through the sleeve 43 into the notch of the threaded body 41, thereby tightening or loosening the threaded body 41, so as to move the sleeve 43 firmly connected to the side wall 10 along the threaded body 41 relative to the bottom plate 42 against the cast surface layer.

[0051] Each claw screw system 50 comprises a bracket 51 in which a screw 52 with a claw 53 at the end is mounted. The screw 52 of each system can rotate freely and is fixed in a translationally movable manner in the bracket 51. The head of the screw 52 is accessible from the front surface of the top part of the bracket 51, and the end of the screw 52 with the claw 53 passes through the bottom part of the bracket 51 so that the hook of the claw 53 protrudes from the bracket 51.

[0052] More specifically, if Figure 2 As shown, the claw screw system 50 is installed in the side wall 10, wherein the claw 53 is in a retracted position relative to the outer surface of the panel 10B of the side wall 10. Each panel 10B of the side wall 10 is provided with two claw screw systems 50, each claw screw system 50 is associated with a window 15 provided in the panel 10B.

[0053] The support 51 of each claw screw system 50 is placed in a housing defined between the bottom of the molding 16 and the corresponding panel 10B of the side wall 10, through one of the windows 15 of the side wall 10 and the grooves 17A, 18A of the flanks 17, 18 of the molding 16, so as to Figure 3 As shown, the teeth 51A provided at the edge of the bracket 51 are hooked on the edge 15A of the corresponding window 15, and a portion 51B of the bracket 51 abuts against the side flanks 18A of the molding 16 on both sides of the window 15. In this way, each bracket 51 is locked in the cavity of the side wall 10, with its central part emerging through the window 15 (flush with the outer surface of the panel 10B), and the screw 52 extends perpendicularly to the front edge 11 and the rear edge 12 of the side wall 10.

[0054] The end portion of each screw 52 with the claw 53 extends rearwards beyond said panel 10B of the side wall 10, so that each claw 53, in the retracted position, extends away from the rear edge 12 of the side wall 10 without protruding from the outer surface of the panel 10B of the side wall 10. Contrary to each claw 53, the upper portion of the bracket 51 of each claw screw system 50 fills the groove 17A of the flank 17 of the molding 16, and the front surface of this upper portion extends flush with the front surface of said flank 17. Figure 2 As shown, the head of each screw 52 is accessible from the front surface of the flank 17 of the molding 16 of the side wall 10. By tightening the screw 52 of each system, the claw 53 moves along the threaded body of the screw 52. The claw 53 slides on the inclined surface of the bracket 51, thereby pivoting to the extended position, in which the hook portion of the claw 53 forms a protrusion on the outer surface of the corresponding panel 10B of the side wall 10, and then the claw 53 moves upward along the threaded body of the screw 52 until it engages with the rear edge of the raised floor or the built-in box.

[0055] The support 21 shown here is used for horizontal mounting of the connection module in the floor socket 1. Of course, other types of supports can be envisaged, such as supports for vertical mounting. The support 20 is a metal frame that is inserted inside the side wall 10. It comprises four panels 20A, 20B that are parallel to each other. The two parallel panels 20A comprise facing slots 21 for horizontal mounting of the connection module. The two panels 20A comprise two flanges 23 that can abut against the bosses 13 of the side wall 10 and are provided with holes for fixing the support 20 to the side wall 10 by means of screws.

[0056] like Figure 2 As shown, when the support member 20 abuts against the boss 13 of the side wall 10, its panels 20A, 20B extend the panels 10A, 10B of the side wall 10 toward the rear, and retreat slightly toward the inside relative to the panels 10A, 10B, so as to avoid interference with the mounting devices 40, 50. The narrow slots 21 of the facing panels 20A form the gears for the connection modules to be installed at different depths inside the floor socket 1.

[0057] The cover plate 30 has a square outline here, which matches the square outline of the front opening 11A of the floor socket 1. In the closed position, as shown in FIG. Figure 8 As shown, the cover plate 30 is completely inserted into the side wall 10 to close the front opening 11A, so that the front edge 30A of the cover plate 30 is along the front edge 11 of the side wall 10 but does not exceed the front edge 11 of the side wall 10 .

[0058] Of course, in a variation not shown, the front opening of the floor socket is circular, and the cover plate having a circular contour matches the contour of the front opening.

[0059] The cover plate 30 is a component assembled from metal elements. It includes an outer frame 31, which is formed by four sides 31A, 31B that are parallel to each other, and the height of which determines the thickness of the cover plate 30. The circumferential front edge 30A of the cover plate 30 is formed by the front edges of the four sides 31A, 31B of the outer frame 31. The cover plate 30 includes a closed wall 34 with a square outline, which is integrally connected to the outer frame inside the outer frame 31. Figure 1In particular, the enclosed wall 34 comprises two aligned journals 36 which protrude from two parallel edges of the enclosed wall 34. The two journals 36 pass through two grooves 35 provided in two parallel sides 31B of the outer frame 31, thereby protruding from the outer surface of the frame. Finally, inside the outer frame 31, the cover 30 comprises a box 33 fixed to the outer frame 31 and the enclosed wall 34. This box 33 contains a locking mechanism for locking the cover 30 in the closed position on the side wall 10 of the floor socket 1. This locking mechanism is conventional and will not be described here. It comprises a locking system that can be activated by a control touch panel 37 accessible from the front surface of the cover 30.

[0060] like Figures 1 to 9 As shown, two opposite parts of the side wall 10, here two parallel panels 10B, are provided with two grooves 100, 200, each of which has a rotational portion 120, 220. The rotational portions 120, 220 of the grooves 100, 200 form seats for receiving the journals 36 of the cover plate 130. The cooperation between the two journals 36 of the cover plate 30 and the two rotational portions 120, 220 of the grooves 100, 200 enables the cover plate 30 to be moved in a straight line. Figure 6 The open position shown is Figure 8 The side wall 10 is pivoted between the closed positions shown.

[0061] according to Figures 1 to 9 In the example shown, the rotational portions 120 , 220 of the two grooves 100 , 200 are parallel arc-shaped portions extending along two equal lengths of a circle C.

[0062] According to the salient features of the floor socket 1, such as Figure 2 and 3 As shown, at least one of the grooves 100, 200 has a guide portion 110 and a coupling portion 130, wherein the guide portion 110 is different from the rotating portion 120 and at least a portion 111 thereof extends along an axis X1 parallel to the front edge 11 of the side wall 10, and the coupling portion 130 has a tortuous channel form and establishes a connection between the rotating portion 120 and the guide portion 110. The coupling portion 130 has a stop edge 131, which faces the rotating portion 120 and extends in a direction Y perpendicular to the front edge 11, and the distance d of the stop edge 131 is greater than or equal to the height H of the journal 36 (see Figure 3 and 9 ).

[0063] Here, if Figure 2 As shown, the two grooves 100 , 200 are different, the groove 100 includes a rotating portion and an insertion portion connected by a joint portion, and the other groove 200 includes only a rotating portion 220 .

[0064] according to Figures 1 to 9 In the example shown, the grooves 100, 200 are formed together with the side wall 10. They are formed by cutting the panel 10B so as to be open on two opposite surfaces of the panel 10B of the side wall 10. In particular, the groove 100 is defined between two continuous longitudinal edges 100A, 100B, which extend parallel to each other from an end edge 100C located at the end of the insertion part 110 to another end edge 100D located at the end of the rotation part 120.

[0065] Each groove 100, 200 has a width l which - apart from the clearances allowed - corresponds to the height H of each journal 36. Thus, the guide portion 110, the engagement portion 130 and the rotation portion 120 of the groove 100 have the same width l, measured between the longitudinal edges 100A, 100B of the groove 100 (see Figure 3 ).

[0066] like Figure 3 It is particularly shown that the coupling portion 130 includes a first end segment S1 and a second end segment S2, wherein the first end segment S1 is located on the same side as the stop edge 131 and is connected to the guide portion 110, and the second end segment S2 is different from the first end segment S1, faces the stop edge 131 and is connected to the rotating portion 120.

[0067] Advantageously, if Figure 3As shown, starting from the end edge 100C, the guide portion 110 comprises a horizontal portion 111 and an inclined portion 112, the horizontal portion 111 extending along an axis X1 parallel to the front edge 11 of the side wall 10, and the inclined portion 112 extending from the horizontal portion 111 in the direction of the front edge 11 along an axis X2 inclined relative to the front edge 11. The axes X1 and X2 form an angle of, for example, about 30 degrees. This inclined portion 112 leads to a first end section S1 of the engagement portion 130. The engagement portion 130 has an L-shaped or stepped profile and is formed between two horizontal edges 133, 135 of the front edge 11 of the side wall 10 and two vertical edges 131, 134 perpendicular to the front edge 11. The horizontal edge 133 and the vertical edge 134 belong to the longitudinal edge 100A of the groove 100, and the horizontal edge 135 and the vertical edge 131 belong to the other longitudinal edge 100B of the groove 100. The vertical edge 131 of the engagement portion 130 forms a stop edge which is attached to the edge of the inclined portion 112 of the guide portion 110 via a circular edge 132 over which the corresponding journal 36 of the cover plate 30 passes. The horizontal edge 133 of the engagement portion 130 extends above the circular edge 132 and is located between the circular edge 132 and the front edge 11 of the side wall 10.

[0068] Figure 4 and 5 The installation of the cover plate 30 on the side wall 10 is shown. The installation is achieved by orienting the cover plate 30 approximately along the axis Y perpendicular to the plane P of the front opening 11A of the side wall 10, so that one journal 36 of the cover plate 30 is inserted into the rotating part 220 of the groove 200, and the other journal 36 of the cover plate 30 is inserted into the end of the horizontal part 111 of the insertion part 110 of the groove 100, and then sliding this journal 36 to the inclined part 112 of this insertion part 110 until it passes over the circular edge 132 and enters the engagement part 130 via the end section S1. When the journal 36 passes over the circular edge 132, it slides in the engagement part 130 along the axis Y until it enters the rotating part 120 via the end section S2 (see Figure 6 and 7 ). Figure 6 and 7 The position shown corresponds to the open position of the cover 30 on the side wall 10 .

[0069] To close the cover 30 on the side wall 10, the journal 36 of the cover 30 is slid in the rotating parts 120, 220 of the grooves 100, 200, thereby turning the cover 30 from the vertical position along the axis Y to the vertical position. Figure 8 and 9The cover 30 is in the horizontal position shown, at which time, the cover 30 is inserted into the front opening 11A of the vertical wall 10 and abuts against the flank 17 of the profile 16 of the side wall 10. In this way, the profile 16 limits the pivoting movement of the cover 30 and indexes the closed position of the cover 30. In the closed position, the corresponding journal 36 of the cover 30 is placed at the end of the rotating part 120 and abuts against the end edge 100D of the groove 100 (see Fig. 9 ).

[0070] The cover plate 30 is opened and closed by moving the journal 36 of the cover plate 30 in the rotating portion 120 , 220 of the groove 100 , 200 .

[0071] When the cover plate 30 is opened, the journal 36 will not be accidentally inserted into the insertion portion 110 of the groove 100, causing the cover plate to be removed, because at the end of the opening process, the journal 36 is blocked in the engagement portion 130 by the stop edge 131 just at the entrance or exit of the rotating portion 120 (see Figure 6 and 7 ).

[0072] Thus, in order to remove the cover plate 30, it is necessary to deliberately act on the cover plate 30 in the open position, such as Figure 6 As shown, it is lifted along the axis Y and the journal 36 is moved in the engagement portion 130 along the axis Y until it passes over the circular edge 132 and is inserted into the inclined portion 112 of the insertion portion 110 and then slides in the horizontal portion 111 of the insertion portion 110 until the end edge 100C of the groove 100.

[0073] The present invention is not limited to the above detailed description, but other various modifications may be made.

[0074] For example, it is conceivable that Figures 10 to 14 Another embodiment shown, according to which the floor socket 1' is a non-flush standard box, which comprises a side wall 10' made of metal material, the side wall 10' comprises four panels 10'A, 10'B parallel to each other, and has a front edge 11', which defines a front opening 11'A of the floor socket 1' in a plane P (see Fig.12 ).

[0075] The panels 10'A, 10'B include an offset in the upper part, thereby forming a boss 10'C extending along the front edge 11', and a peripheral upper flange 10'D, the free edge of which forms the front edge 11' (see Fig.12 ).

[0076] According to this embodiment, a metal upper part 18' is attached to the circumferential upper flange 10'D and the boss 10'C. The upper part 18' forms an outer flange 18'A of the floor socket (see Fig.10 , 11 , 13 and 14), which are along the front edge 11' and are intended to cover part of the front surface of the receiving floor around the embedded opening of the floor socket 1'.

[0077] The upper part 18' comprises parts 18'B, 18'C covering the inner surface of the upper chime 10'D and the front surface of the boss 10'C. These parts 18'B, 18'C are attached to the flange 18'A by a circumferential chime 18'D which merges with the front edge 11' of the side wall 10'.

[0078] The groove 100' comprises a rotating portion 120' and a guide portion 110', which are attached together by a joint portion 130', and is formed by a portion 10'D of the side wall 10' and an insert 60' attached to this side wall 10' and made of synthetic material, so that the groove 100' is not open to the outside of the floor socket 1', and has a bottom formed by a portion 10'D of the side wall 10'.

[0079] More specifically, the insert 60' is a small triangular component, fixed on the boss 10'C, and pressed against the inner surface of the upper flange 10'D of the side wall 10' (see Fig.12 ).like Fig.10 As shown, the groove 100' is defined by the edge of this insert 60' (which forms the longitudinal edge 100'B of the groove 100'), depending between the circumferential ridge 18'D of the upper part 18' of the said edge of the insert 60' (which forms the other longitudinal edge 100'A of the groove 100') and the inner surface of the upper ridge 10'D of the side wall 10' (which forms the bottom of the groove 100'). The edge of the insert 60' includes a horizontal portion 61' extending along an axis X1 parallel to the circumferential ridge 18'D and an inclined portion 62' extending along an axis X2 inclined from the horizontal portion 61' in the direction of the circumferential ridge 18'D. The horizontal portion 61' and the inclined portion 62' define the horizontal portion 111', the inclined portion 112' and the insertion portion 110' of the groove 100' with the circumferential ridge 18'D. The edge of the insert 60' comprises, at the end of its inclined portion 62', a dome 63' and a straight portion 64' extending along an axis Y perpendicular to the circumferential ridge 18'D. The straight portion 64' forms a stop edge 131' for the engagement portion 130' of the groove 100'.

[0080] Here, the engaging portion 130 ′ and the rotating portion 120 ′ are integrated into one.

[0081] The journal 36' of the cover plate 30' is perpendicular to the plane P of the front opening 11'A, and it engages with the insertion portion 110' of the groove 100' and can slide along the edge of the plug 60' until it passes over the dome of the plug 60' and is placed in the rotating portion 120' (see Fig.13 and 14 ). The cover plate 30' can be pivoted between an open position and a closed position without the journal 36' accidentally coming out of the rotating portion 120' of the groove 100', since it is retained in this rotating portion 120' by means of the stop edge 131' of the engagement portion 130'.

[0082] Thus, in order to remove the cover 30', it is necessary to deliberately act on the cover 30' in the open position, such as Fig.13 and 14 As shown, it is thereby lifted along the axis Y and the journal 36 ′ is moved along the axis Y in the engagement portion 130 ′ until it passes over said dome 63 ′ of the insert 60 ′ and is inserted into the insert portion 110 ′.

[0083] Of course, various other modifications may be made to the present invention within the scope of the appended claims.

[0084] It is in particular conceivable that the side wall of the floor socket is a cylindrical wall which defines a circular front opening. The cover plate is then of circular profile and has a diameter which is equal to the diameter of the front opening of the floor socket except for the allowed clearance.

[0085] In addition, it is also conceivable that the shape of the non-opening groove of the second embodiment described above is not derived from the attached plug-in, but is obtained by integral molding with the side wall of the floor socket.
