Description

LIST OF THE FIGURES AND DESCRIPTION THEREOF

[0033] FIG. 1

[0034] Furniture assembly (17) between two furniture panels (1,2), such as with the invention. The figure shows two panels (1,2). Several bores (4) are present in the face (V1) of the first panel (1). These bores (4) may be blind bores, but may also be through-bores. At the longitudinal end of the panel (2), two connecting elements (3) are present. This longitudinal end is a face (V2) in which the connecting elements (3) are situated. It should be understood that it is possible for fewer or more connecting elements (3) to be present and that, in addition, these connecting elements (3) may be combined with, for example, positioning bodies or other connecting elements (3). In order to produce a connection which is as beautiful as possible, the face (V1) of the first panel and the face (V2) of the second panel should adjoin each other as closely as possible. The way in which this may be achieved is explained in further drawings.

[0035] Both the first and the second panel have a groove (5). This groove serves to accommodate e.g. a back wall or a bottom panel. These grooves (5) are directed towards the inside of the furniture connection. It should be understood that these panels may contain several more grooves, e.g. in order to fit runners for opening and closing a drawer.

[0036] The connecting element (3) consists of an elongate securing part (18) which is anchored in the one panel (1), and furthermore comprises a bent engagement part (19) consisting of a back part (6) and a tongue-shaped part with a pointed end (7) situated opposite. The end (7) of the engagement part (19) is turned towards the side different from that of the groove (5), which means that, in order to connect the two panels at right angles, the second panel will have to be turned, starting from the other side of the groove, in the direction of the bottom groove (5) of the second panel. This assembly is specified in more detail in the following drawings.

[0037] The connecting element (3) may be made from metal, a metal alloy, a plastic, wood, a WPC, a composite or optionally from the carrier material of the furniture panel (2) itself.

[0038] The carrier material of the panels may differ. Thus, it is possible for it to be made of a chipboard panel, an MDF panel, a WPC, a multiplex panel or another wood-based panel material. Plastic panels are also possible. MDF, chipboard or multiplex panels do have the advantage that they are largely layered, which makes it possible for the end (7) of the engagement part (19) to penetrate the wall of the bore (4) more efficiently, due to the fact that the relatively sharp tongue can penetrate between the layers of the carrier material.

[0039] The furniture panels (1 and 2) are at least partly provided with a decorative top layer. This top layer may be a paper sheet, a plastic film, a lacquer or a variant thereof.

[0040] These sheets/films are generally glued to the carrier material by means of a glue. Other types of decorative sheet/film are also possible.

[0041] FIG. 2a

[0042] Drawing of a furniture assembly (17) according to the invention. The figure shows a top view of the panel (1) and the panel (2). The first panel (1) is shown in cross section at the location of the axis of the bore (4). The direction of the hatching of this cross section also indicates the layer direction of the carrier material. In many cases, this carrier material will be an MDF panel or a chipboard panel and these panels or panel materials show a well-known layered construction parallel to the face (V1) containing the bore (4). This layered construction is ideal for ensuring that the (pointed) end (7) of the engagement part (19) of the connecting element (3) can readily penetrate between the layers in the wall of the bore (4) upon assembly of the two panels.

[0043] On the panel (2), the face (V2) is specified at the longitudinal end of the panel (2). In this head-end face (V2), the connecting element (3) is anchored by means of an elongate securing part (18). This connecting element (3) consists of an elongate securing part (18) and an engagement part (19) which is in turn constructed from a back part (6) and a tongue-shaped part which is largely situated opposite the latter and has an end (7). The back part (6) is composed of 2 parts, i.e. a part (6B) which is perpendicular to the face (V2), and a part (6A) which is at less than 90° with respect to the face (V2). This helps to make simple assembly possible and will be discussed later in this document. It is evident that other embodiments are also possible. The pointed end (7) of the engagement part (19) is sharp, but this is not always necessary although it does make assembly easier. Thus, the pointed end (7) of the engagement part (19) may also have a rounded point or a levelled point. Thus, it is also possible for the engagement part (19) to be provided with a barb, so that the latter provides some resistance to being removed again after the pointed end (7) has penetrated in the wall of the bore (4), so that the perpendicular connection remains reliably upright upon assembly. This assists assembly.

[0044] FIG. 2b

[0045] Assembly of a perpendicular connection between two furniture panels (1,2). A furniture panel (2) is introduced into the other furniture panel (1) at an angle of less than 90° with respect to the other furniture panel (1). In this case, the connecting element (3) is introduced in the bore (4) of the second panel.

[0046] During this operation, the pointed end (7) of the engagement part (19) has not yet penetrated in the wall of the bore (4).

[0047] In order to obtain a beautiful connection, the furniture panel (2) will continue to be inserted into the panel (1) until a point of the face (V2) at the longitudinal end of the furniture panel (2) touches the face (V1) of the other furniture panel (1).

[0048] FIG. 2c

[0049] Assembly of a perpendicular connection between two furniture panels. When the furniture panel (2) is completely in the other panel (1), a rotating movement/force (Fr) of the first furniture panel (2) with respect to the other furniture panel (1) is started, in the direction of the back part (6) of the engagement part (19). When executing this rotating movement/force (Fr), at least a part of the back side (6) of the connecting element (3) exerts a force (Fd′) on the wall of the bore (4), and the end (7) of the engagement part (19) of the connecting element (3) penetrates into the wall of the bore (4) by exerting a force (Fd″) on the wall of the bore (4). As a result thereof, a connection is brought about between the two furniture panels. This rotating movement/force (Fr) continues until the furniture panel (2) is at ±90° with respect to the other furniture panel (1). At this point, the connection has been fully achieved.

[0050] In principle, this assembly and build-up of forces may be compared to that of a lever. The length of the furniture panel (2) is long compared to the distance between the end (7) of the engagement part (19) and the face (V2) of this furniture panel (2). As a result thereof, the force Fd″ which the end (7) of the engagement part (7) exerts on the wall of the bore (4) will always be large, also when exerting a minimal rotary force (Fr) on the furniture panel (2). As a result thereof, the perpendicular assembly of these two panels is child's play and simple. In addition, due to this large build-up of forces, it is not always necessary for the end (7) of the engagement part (19) to be sharp. This may also be spherical or blunt, depending on the requirements of the connection and/or the carrier material used.

[0051] FIG. 2d

[0052] Furniture assembly (17) of two furniture panels. The connection is fully completed.

[0053] The furniture panel (2) is at ±90° with respect to the other furniture panel (1). The back part (6) now presses partly against the wall of the bore (4), while the end (7) of the engagement part (19) at least partly penetrates into the wall of the bore (4). The part (6B) of the back part (6) which presses against the wall of the bore (4) is approximately perpendicular with respect to the face (V2) of the furniture panel (2). It will be clear that this does not always have to be the case. Thus, there are various embodiments in which the part (6B) which presses against the wall of the bore (4) is not at a right angle of 90° with respect to the face (V2) of the furniture panel (2). This will be discussed later in this document.

[0054] FIG. 3a

[0055] Detail of the connecting element (3) of a furniture panel (2) and of the bore (4) in the other furniture panel (1) for producing a perpendicular connection. It shows the distance (A1), i.e. the distance between the back part (6B) which presses against the wall of the bore (4) upon assembly and the end (7) of the engagement part (19). Diameter (D1) is again the diameter of the bore (4) in the other furniture panel (1). In order to produce an assembly, the distance (6B) has to be greater than the diameter (D1) of the bore (4). Then, the end (7) of engagement part (19) will always have penetrated into the wall of the bore over a distance (A3).

[0056] In addition, the angle α is indicated, i.e. the angle between the face V2 and the bottom face (V5) of the engagement part (7). This angle is important in order to produce a satisfactory connection between the face (V2) and the face (V1). This is explained in more detail in the drawing (3b).

[0057] FIG. 3b

[0058] Perpendicular furniture assembly (17) between two furniture panels. The connection is fully completed.

[0059] The furniture panel (2) is at ±90° with respect to the other furniture panel (1). The back part (6) now presses partly against the wall of the bore (4), while the end (7) of the engagement part (19) at least partly penetrates into the wall of the bore (4). The part (6B) of the back part (6) which presses against the wall of the bore (4) is approximately perpendicular with respect to the face (V2) of the furniture panel (2).

[0060] Due to the fact that the face (V5) on the underside of the engagement part is at an angle α with respect to the plane (V2), the engagement part (7) is pulled slightly further into the bore upon assembly, that is to say if the engagement part is situated at a depth of A3 in the wall of the bore, the connecting element (3) together with the furniture panel (2) will be pulled closer towards the bore. As a result thereof, a beautiful connection between the face (V2) of the furniture panel (2) and the face (V1) of the second furniture panel (1) is achieved. Face (V2) then exerts a pressure force (Fd) on the face (V1) of the first furniture panel (1). How far the furniture panel (2) is pulled towards the second panel (1) is directly proportional to the angle α and the depth A3. However, α must not be excessively large, because otherwise it reduces the connection and may cause the connecting element (3) to slide out of the bore (4) in case of large tensile forces. In addition, the distance (A3) (=the difference between the end (7) of the engagement part (19) and the part (6B) of the back part (6) which pushes against the wall of the bore (4)) must not be chosen too large compared to the diameter D1 of the bore (4), because otherwise it may be impossible to fit due to the fact that the lever has to overcome too great a force.

[0061] FIG. 3c

[0062] Connecting element (3) according to the invention and an associated bore (4). The drawing indicates the distance A1, which is the distance between the outermost point of the back part (6) and the end (7) of the engagement part (19). Distance A5 is the perpendicular distance between the end (7) of the engagement part (19) and the face (V3) of the side piece (2). The distance (A4) is the distance between the end (7) of the engagement part (19) and the face (V2) of the longitudinal end of the side piece (2). The aim is that, after assembly, the face (V2) of the side piece (2) adjoins the plane (V1) of the front piece (1) as closely as possible. In order to achieve this, it is important to know the angle (δ) at which the turning movement is started. The distance A5 has to be chosen such that A4=A6 (=the distance between the face (V1) of the first panel (1) and the end (7) of the engagement part (19) at the start of the turning movement). This is discussed in more detail in point 3d.

[0063] FIG. 3d

[0064] The side piece is in a starting position to begin the turning movement. The face V3 of the second panel is at an angle δ with respect to the perpendicular on face V1 of the first panel. With this starting position, it is characteristic that the face V2 of the second panel makes point contact (CP1) with the plane (V1) of the first panel. The back part (6) makes contact (CP3) with the wall of the bore (4). On the opposite side, the end (7) of the engagement part (19) makes contact with the wall of the bore (4). In order to ensure that distance A6=A4, then A6=(A4*cos(δ))+(A5*sin(δ)). In principle, there will also be tolerance, but it is important that both faces (V2 and V1) adjoin one another as closely as possible in the assembled state.

[0065] FIG. 4a

[0066] Drawer, wherein three furniture panels are connectable to each other by a connection according to the invention. The drawer consists of five panels, the front panel (1), two side panels (2,13), the rear piece (10) and the bottom (11). The side panels (2,13) and the front panel (1) have to be connected by means of the connecting technique according to the invention. The longitudinal ends of the side panels (2) are provided with two connecting elements (3) according to the invention.

[0067] The front panel (1), the two side panels (2,13) and the rear piece are provided with one or several grooves (5). These grooves have various functions, such as a bottom groove, a connecting groove, a runner groove. Also, the panels may be provided with various bores. It should be understood that the number of grooves and bores in the panels may vary infinitely.

[0068] In this case, the drawer has to be assembled by first turning the side pieces in the front, then fit the bottom and clamp the rear piece in the side pieces (2 and 13) at the end via a clamp coupling by means of the supplied assembly pegs. These pegs may also already have been incorporated in the drawer. This assembly is discussed in greater detail in this document. It should be understood, however, that there are alternative ways of assembling a drawer in which the connection of the invention is incorporated. These alternative ways may differ in the sequence and/or the clamp couplings used.

[0069] FIGS. 4b1; 4b2 and 4b3

[0070] Furniture assembly of two furniture panels at right angles to each other according to the invention. The side panel (2) is fitted in the front panel (1) by means of a connecting element (3) according to the invention. FIGS. 4b2 and 4b3 show a detail of a cross section of the bore (4) during assembly. In his case, the connecting part (3) is inserted into the bore (4) at an angle in a first stage. Thereafter, pressure is exerted on the wall of the bore (4) by means of a lateral turning movement of the side panel (2) via the back part of the connecting element (3). Then, the end (7) of the engagement part (19) starts to penetrate into the wall of the bore (4).

[0071] The penetration finishes when the side panel is more or less at right angles to the front panel (1). The hatching (R) is in the same direction as the layer direction of the carrier material of the front panel (1). In many cases, this carrier material is a wood-based panel material, such as an MDF or a chipboard panel. These panels have a distinct layer direction and this layer direction runs parallel to the plane in which the bore (4) is provided. Due to the fact that these panels have a distinct layer direction, the engagement part (19) of the connecting element (3) is able to readily penetrate into the wall of the bore. It should be understood, however, that this technique may also be used for panel materials or components which are not layered or where penetration into the wall of the bore (4) of the engagement part has to take place at right angles to the layer direction of the respective panels.

[0072] The turning direction of the side panel (2) with respect to the front (1) is now from the inside to the outside, but this may also be the other way around. This may be of interest for certain assembly methods or embodiments. Thus, it may also be the case that the side panel (2) has to be fitted entirely on the side of the front panel, in which case it is better if the engagement part (7) is turned towards the inside of the drawer, because otherwise it might project from the side of the front panel (1), which would not be acceptable aesthetically.

[0073] FIGS. 4c1; 4c2 and 4c3

[0074] Assembly of the second side panel (13) in the front panel (1) according to the invention. The assembly is the same as the first side panel (2) discussed in FIG. 4b1.

[0075] FIGS. 4c2 and 4c3 discuss the detail of the cross section of the bore (4) during assembly.

[0076] FIGS. 4d1; 4d2 and 4d3

[0077] Assembly of the two side panels (2,13) in the front panel (2) according to the invention. The contrast with respect to the drawings discussed above is that the side panels (2,13) now have to be turned from the outside inwards instead of the other way round. This may result in advantages for reasons of assembly technology, such as with the assembly of the rear piece. This is due to the fact that this is clamped between the side panels (2,13). If the side panels have to be turned from the inside out and the rear piece is already provided with integrated coupling means in the longitudinal ends, the side pieces have to be folded over by more than 90°, which could cause damage to the carrier material and/or to the connecting element (3). In this case, it is therefore more practical to turn from the outside inwards. This will be discussed in more detail in this document.

[0078] FIG. 4e

[0079] Assembly of a drawer box according to the invention. The two side panels (2,13) are already fitted in the front panel (2). The bottom (11) has now been pushed in the box from the rear. To this end, special bottom grooves have been provided in the side pieces (2,13), the front (2) and the rear piece (10).

[0080] FIGS. 4f1 and 4f2

[0081] Assembly of a drawer box according to the invention. The two side panels (2,13) are already fitted in the front panel (2) and the bottom (11) has already been pushed in the box. Now, the rear rear piece is being fitted. To this end, grooves are provided on the rear side of the two side panels (2,13). The longitudinal ends of the rear piece are also provided with coupling means in the form of screw elements. These are situated completely in the rear piece and can be screwed out by means of a screwdriver. It should be understood that alternative connections are possible, as will be discussed in more detail in this document.

[0082] FIGS. 4g and 4h

[0083] Assembly of a drawer box according to the invention. By means of a screwdriver (12), the screw elements (14) are screwed out of the longitudinal ends of the rear piece. As a result thereof, they rotate in the bores (42) in the side pieces (2,13) and a connection is produced between the intermediate piece (10) and the side pieces (2,13).

[0084] FIG. 4i

[0085] Assembly of a drawer box according to the invention. Instead of a screw element (14) which is installed in the rear piece, the connection is now created between the rear piece (11) and the side pieces (2,13) by inserting special plugs (43) from outside into the rear piece via the side pieces (2,13). As a result thereof, a connection is produced between the side pieces and the rear piece.

[0086] FIGS. 4j1; 4j2; 4j3 and 4j4

[0087] Assembly of a drawer box according to the invention. This is again an alternative way of fitting the intermediate piece (10) in a drawer box. The longitudinal ends of the rear piece are provided with coupling means (41) comprising barbs. These coupling means have to be pushed into the bores (42) provided for this purpose. Both bores (42) and the coupling means (41) are provided with barbs, resulting in a strong connection. These coupling means (41) may have been screwed into the rear piece, but may also have been glued, for example. The bores (42) are now continuous, but may equally be blind, as a result of which nothing is visible on the outside of the drawer box.

[0088] FIG. 5

[0089] Connection between two furniture panels according to the invention. In addition to a good connection between the side pieces (2,13) and the front (1), the position of the side pieces with respect to the front is of great importance. Therefore, it may be of interest to also provide an additional dowel in addition to the connecting elements (3). This then ensures a perfect positioning. However, in many cases this is superfluous. After all, the connecting element (3) can not only ensure a connection, but in many cases a positioning as well. Therefore, an additional dowel is not always required.

[0090] FIGS. 6.1; 6.2; 6.3 and 6.4

[0091] Connecting element (3) according to the invention. Between the back part (6) and the end of the engagement part (19), a groove (16) is provided. It serves as a tension control during assembly. During the turning movement, a dead point or dead force is overcome. The compressive stress which occurs between the end (7) and the back part (6) pushes the two parts (6 and 7) towards each other, until the smallest distance has been bridged (FIG. 6.3). The advantage of such a groove is that significantly less force has to be used and also that, once the side piece has been fitted, it remains approximately perpendicular with regard to the front (1), since a dead point has been overcome. The figure shows that the groove (16) is arranged at an angle (α). Depending on the desired tension or material, this angle α may be different. In addition, the depth of the groove (16) may also be different.

[0092] FIGS. 7.1; 7.2; 7.3 and 7.4

[0093] Connecting element (3) according to the invention. The figures are similar to FIGS. 6.1-6.4, but with the significant difference that the engagement part (19) consists of various tongues/projections (22). As a result thereof, the grip which is created may be greatly increased. Between the tongues, there is a small flat piece which may be regarded as a stop. As a result thereof, penetration of the engagement part (19) into the wall of the bore (4) is limited. As a result thereof, the connection gains additional stability and a better positioning of the side piece (2) with respect to the front (1) is achieved.

[0094] FIGS. 8.1 and 8.2

[0095] Connection according to the invention. Connecting element (3) may take various forms. Here, the end (7) of the engagement part (19) has a round contour. This may be of interest during penetration into the wall of the bore. In addition, the back part (6) has a rounded contour. It should be understood that several forms are possible and that these forms are combinable with the technical characteristics already discusses above.

[0096] FIGS. 9.1 and 9.2

[0097] Connection according to the invention. Connecting element (3) may take various forms. Here, the end (7) of the engagement part (19) has a straight contour. This may be of interest during penetration into the wall of the bore. In addition, the back part (6) has a rounded contour. It should be understood that several forms are possible and that these forms are combinable with the technical characteristics already discussed above.

[0098] FIGS. 10.1 and 10.2

[0099] Connection according to the invention. The coupling means (3) may take various forms. Here, the end (7) of the engagement part (19) has a straight contour. This may be of interest during penetration into the wall of the bore. The back part (6) also has a straight contour. As a result thereof, the back part (6) is more likely to make a point contact with the wall of the bore (4), while with a round contour, there is more likely to be a face which makes contact. It should be understood that several forms are possible and that these forms are combinable with technical characteristics which have already been discussed.

[0100] FIG. 11

[0101] Cross section of a connection between a side panel (2) and a front panel (1). There are two connecting elements (3) present. These connecting elements (3) are glued into the side panel (50). However, various fitting options are known for fastening the connecting element (3) in the side piece. Such as gluing, screwing, clamping or melting. In certain cases, the connecting element (3) may also be made of the same material as the side panel (2) itself. Just think of a side piece made of plastic or metal, or optionally of wood, in which the connecting element (3) is milled.

[0102] FIG. 12

[0103] A connecting element (3) according to the invention. The connecting element (3) is fitted in the side piece (2) by means of a screw (51) which has been screwed through the connecting element (3) and into a bore of the side piece (2). The advantage of this type of attachment is that the engagement part (19) can easily be fitted in the correct direction. Optionally, barbs could be provided in the longitudinal direction of the connecting element (3), so that the latter is unable to rotate in the bore after assembly.

[0104] FIG. 13

[0105] A connecting element (3) according to the invention. The connecting element is fitted in the side piece (2) by screwing it into the bore (80) of the side piece. This is an inexpensive and quick way of assembling. In addition, it offers the advantage that the connecting element (3) is supplied separately, as a result of which the assembler still has to fit it. The connecting element consists of an elongate securing part (18) and an engagement part (19), wherein the engagement part is composed of, on the one hand, a back part (6) and, on the other hand, an end (7).

[0106] FIGS. 14a and 14b

[0107] A connecting element (3) according to the invention. The connecting element (3) is fitted in a bore (80) in the longitudinal end of a panel (2). There is another panel (1) which is provided with a bore (4). The connecting element (3) is provided with a groove (16) which separates the end (7) of the engagement part (19) from the back part (6). As a result thereof, the engagement part (19) and/or the back part (6) become slightly elastic, as a result of which they/it can deal with a certain degree of bending stress. This makes it possible to both turn (FIG. 14b) and also snap (=laterally insert/FIG. 14a) the panel (2) into the bore (4) of the first panel (1). In certain cases, this may be necessary in order to assemble the panels or a box in its entirety.

[0108] FIGS. 15a and 15b

[0109] A connecting element (3) according to the invention. It is a variant of the connecting element (3) discussed in FIGS. 14a and 14b, the difference being that a small barb/projection (21) is provided on the back part (6) as well. This may be of interest in order to prevent the connecting element (3) from becoming detached by turning or in order to achieve a better attachment.

[0110] It should be understood that other embodiments or combinations of the above-described embodiments are possible.

[0111] FIGS. 16a;16b and 16c

[0112] A rear view (16.a), a side view (16.b) and a top view (16.c) of a connecting element (3) according to the invention. The end (7) of the engagement part (19) is part of a circular or oval-shaped part.

[0113] The maximum distance (A7) of this oval-shaped part transversely to the connecting line between the end (7) and the back part (6) is slightly to a little smaller smaller than the cross section (D1) of the bore (4) of panel (1). After all, the aim is that this circular or oval-shaped part ensures the positioning of panel (1) with respect to panel (2) in the direction (Z2). It should be understood that still other embodiments are possible. Thus, the positioning in the (Z2) direction may also be ensured by special projections transversely to the connecting line between the end (7) of the engagement part (19) and the back part (6). These projections do not have to form an integral part of the engagement part (19) and certainly do not have to be situated at the same height as the engagement part.

[0114] At the bottom of the engagement part (19), on the side of the end (7), another projection (60) is provided. The distance (A8) of the maximum point of this projection (60) and the maximum point of the back part (6) is slightly to a little smaller than the cross section (D1) of the bore (4) of the panel (1). As a result thereof, the positioning of the panel (2) with respect to the panel (1) is ensured in the direction Z1.

[0115] It should be understood that still other embodiments or forms of the securing part are possible in order to ensure the anchoring of the positioning of panel (1) with respect to the panel (2), both in direction Z1 and in direction Z2.

[0116] FIGS. 17a and 17b

[0117] Cross sections of a assembly comprising a connecting element (3) according to the invention. FIG. 17a again shows a cross section of a connection, seen in top view of the connection, FIG. 17b shows a side view of the connection. The maximum distance (A7) of the oval-shaped or circular part transversely to the connecting line between the end (7) of the engagement part (19) and the back part (6) is slightly to a little smaller than the cross section (D1) of the bore (4) of panel (1). After all, the aim is for this circular or oval-shaped part to ensure the positioning of panel (1) with respect to panel (2) in the direction Z2. This distance (A7) has to be smaller than the cross section (D1) anyway, since it would otherwise not be possible to fit the connecting element (3) in the bore (4), or at least not easily. On the underside of the engagement part (19), on the side of the end (7), a projection (60) is present. The distance (A8) of the maximum point of this projection (60) and the maximum point of the back part (6) is slightly to a little smaller than the cross section (D1) of the bore (4) of the panel (1). As a result thereof, the positioning of the panel (2) with respect to the panel (1) is ensured in the direction Z1. It should be understood that still other embodiments or forms of the connecting element are possible in order to ensure the anchoring of the positioning of panel (1) with respect to panel (2), both in direction Z1 and in direction Z2.

[0118] FIG. 18

[0119] Connecting element according to the invention. It is a variant of a connecting element which has already been described above, the difference being that the back part (6) is now completely straight. This does not hamper assembly and may in certain cases be of interest.

[0120] FIGS. 19a and 19b

[0121] Alternative embodiments of a connecting element according to the invention. FIG. 19a shows that there is a cross (90) on the top of the connecting element (3). This serves to be able to easily screw the connecting element (3) in the side piece (2) by means of a screwdriver.

[0122] FIG. 19b shows that the engagement part (19) has been displaced with respect to the securig part (18). This has the advantage that the bore in the side piece (2) can be drilled slightly further away from the side (V2) of the side piece (2), as a result of which there will be no visible damage or deformation to the side (V2) of side piece (2).
