Abstract

The elastically deformable support strips (4) which are lower than the spring strips (3) each have an elastically deformable centre area (8) between the longitudinal supports (1,2). This centre area is of stronger elasticity than two end areas (9,10) of the support strip directed from the longitudinal supports to the spring strip ends (3a). The support strip (4) is supported on the two longitudinal supports and held on same by connecting elements (11). Swivel movement of the support strip on each support point is possible in the transverse direction to the corresponding longitudinal support and the swivel movements cause the two side edge areas of a support module (7) when stressed at any point to move down from the supporting side.

Description

The present invention relates to a slatted frame for a bed with two longitudinal beams which run essentially in the longitudinal direction of the bed and are spaced apart from one another and with a number of spring strips which run at a mutual spacing and essentially transverse to the longitudinal beams and which together form a support surface for a mattress, as well as opposite the female slats located elastically deformable support slats, via which the female slats are connected to the longitudinal members, the longitudinal members being arranged below the female slats and the outsides of the longitudinal members facing the ends of the female slats being set back relative to the female slat ends, and in each case at least one female slat and one supporting bar are combined with two lateral edge area elements to form a support module.

Such a slatted frame is disclosed in European patent application EP 0 539 644. This shows lower support elements or lower support strips, which are either permanently connected to the side members or have considerable degrees of freedom at the connection points with the side members. It has been shown that the sleeping comfort that can be achieved with the slatted frame can be increased with specially designed support strips and with a corresponding fastening of the latter to the side members. It is important to give the lower support bar a certain deflection characteristic. It is also important to design the attachment of the support strips to the side members so that there are only certain limited degrees of freedom of the support strips relative to the side members.

Furthermore, the lateral connection element or the edge area element, as it is called below, is of great importance. This edge area element, which connects a lower support bar and one or more upper female connectors at their ends and combines them to form a support module, is to be designed such that a pivoting of each individual female connector or a pivoting of all female connectors combined to form a support module transversely to the longitudinal direction of the Side member is possible.

When both the slats and the support strips spring through, they undergo changes in length, which must be compensated for by the edge area elements or the type of fastening of the support module to the side members.

In the present type of slatted frames, it is not the side members, which are hidden laterally below the slats, that are the dominating elements that shape the appearance of the slatted frame, but the strung-together edge area elements. In order for the slatted frame to have an aesthetically pleasing effect, they should be as flat or low as possible, so that the lateral edge areas of the slatted frame are closed by a relatively narrow line. Such a construction gives the viewer the impression of a free-floating slatted frame or bed.

It is the object of the present invention to provide a slatted frame which is improved compared to the prior art.

According to the invention, this object is achieved in that the support strip has an elastically deformable central region which is located between the longitudinal beams and which is more elastic than two end regions of the support strip directed from the longitudinal beams to the spring strip ends, that the support strip is supported on the two longitudinal beams and with connecting elements thereon is held, and that a pivoting movement of the support strip is possible at each support point in the transverse direction to the corresponding longitudinal member, which pivoting movements cause the two lateral edge regions of a support module to move downward at any point from the support side when it is loaded.

Due to the differently strong elastic areas of the support strip, only a relatively weak deflection of the edge areas of the slatted frame is achieved, although the spring deflection of the slats in the middle of the slatted frame is relatively large. This can prevent a person who sits on the edge of the slatted frame from sinking too deeply. By holding down the support bar on the side members in particular Connecting elements at the points where the support bar is supported on the former and through the relatively strongly elastically deformable central region of the support bar, the opposite pivoting movement is achieved at the support points. This counter-rotating swivel movement is responsible for the fact that when the one side slatted frame is loaded, the opposite side slatted frame is not raised, but is also lowered in the direction of loading. This prevents the slatted frame from tipping over under one-sided loads.

With the limiting member, which has each end area of a support strip and which is spaced from the closer longitudinal beam in the unloaded state of the slatted frame, it is achieved that deflection, in particular the edge areas of the slatted frame, cannot take place until a component is destroyed, but to a reasonable degree is limited. It is preferably provided that the maximum deflection of the edge region can be made variable using an adjusting element which is arranged to be adjustable. Since an adjusting member is provided for each support module on both sides of the slatted frame, an individual adjustment of the maximum deflection of the support modules along the slatted frame is possible. With the setting member, a space that is present between the limiting member and the closer longitudinal beam serving as a stop is kept larger or smaller. With increasing deflection, the limiting element then comes to an end sooner or later on the adjusting element. Advantageously, provision can be made to produce the adjusting member from a rubber-elastic mass. As a result, the deflection is not stopped suddenly, but gently braked.

The support strip is supported on the longitudinal beams preferably with a support lug protruding from the support strip above the longitudinal beams, which can be essentially triangular in cross section and can extend in the longitudinal direction of the longitudinal beams essentially over the entire width of the support strip. A triangular tip faces the side members. By means of the connecting elements acting on the support strip, in particular hold-down elements, the support lugs are each held down on the longitudinal beams. A lifting of the support bar from the side members this makes it impossible. On the other hand, pivoting of the support bar at the support points around the support tip of the support nose is possible. The hold-down elements are designed in such a way that the required length compensation of the support strip when the center area is bent can take place with changing loads on the slatted frame.

It can preferably be provided to provide a support element made of an elastic mass between the support lugs and the longitudinal beams. Deflection noises can be avoided on the one hand, on the other hand, the aforementioned possibilities of movement of the support strip at the support points relative to the longitudinal beams are already provided by the elastic mounting. The support element is preferably made of a relatively soft rubber or silicone material or the like and has a notch in which the aforementioned support nose of the support strip is guided. The support element lies on the side members with a plate-shaped support.

The slats of the slatted frame are slightly raised in the middle when not loaded. They have an upward bending curve. When the slatted frame is loaded, the slats spring down and reach a sagging bending curve. The central region of the support strip is now preferably designed such that it is concavely bent relative to the unloaded spring strips. The curvature curve of the support strips is preferably designed such that it corresponds to that of the correspondingly loaded spring strips bent downward. The support strip bent in this way does not disturb the relatively large deflection path of the spring strips. However, it limits the maximum spring deflection without producing an essentially punctiform hard limiting point directed towards the mattress.

Viewed overall, the support strip is preferably also concavely pre-bent over the spring strips. In itself, however, the support strip can be wave-shaped.

After their manufacture, the support strip ends have at least a distance of 5 cm, which runs in a straight line. In this way it is possible, by shortening these ends, to adapt a support strip to a limited extent to different slatted frame widths. The direction of insertion of the support strip ends into the edge area elements remains unchanged after the shortening.

It is provided that the support strips are produced in one piece as an injection molded part, preferably from a thermoplastic. The limiting member can be integrated in the support bar. In order to avoid material accumulation, a rib construction is usually necessary. It is also possible to manufacture the support strips using the so-called gas pressure process. This creates an injection molded hollow body that has a ribless surface on the outside. This has a positive effect on any dust deposits.

According to the invention, it is provided that each edge region element has essentially pocket-shaped holding means for the end of the at least one spring strip and for the end of the supporting strip of a support module, that all holding means are arranged next to one another in the longitudinal direction of the longitudinal beams and do not overlap in this direction and that all holding means bridging, designed as a support element cover wall is present, which connects the holding means to each other.

With this construction, an edge area element has been created which, due to the juxtaposition of the holding means for all ledge ends, has an extremely low construction.

The edge area elements are intended for receiving and holding all facing strip ends, which together form a support module. One of the strips is a lower support strip and at least one is a higher spring strip. Preferred embodiments provide support modules with two spring strips arranged next to one another, the lower-lying support strip being arranged between the two spring strips. For the head-side and foot-side edge areas of the slatted frame, however, edge area elements can also be provided, into which three side-by-side spring strips can be used, the lower-lying support strip being arranged in one of the two spaces between the spring strips.

The edge area element can be plugged onto the mutually facing ends of the spring strips and the support strip. Because of the given construction, in which the edge area element is not also connected to any longitudinal frame, it is necessary to provide means which prevent the edge area element from slipping sideways from the strip ends. According to the invention, securing means are provided for this purpose, which are designed as a type of snap device. In one of the ledge ends, preferably in the end of the support ledge, a notch running transversely to the support ledge can be cut into which a rib, which is arranged on the holding means of the edge area element for the support ledge, engages.

The holding means for the support strip, which, like the holding means for the spring strips, is preferably pocket-shaped, is connected to the top wall of the edge region element via an element which is subjected to torsion and bending. The connecting member can be tongue-shaped. It is used so that the edge area element can be pivoted relative to the support strip in the longitudinal direction of the slatted frame. The spring strips inserted into the corresponding edge region element can thus also be pivoted with respect to the longitudinal members. Between the top wall of the edge area element and the holding means for the end of the support strip, a circular segment-shaped pivot stop is provided, around which the holding means for the support strip can roll when the edge area element is pivoted.

Each holding means for one of the female connectors, which is preferably designed as a pocket surrounding the end of the female connector, is further designed such that the female connector can be tilted within limits transversely to its longitudinal direction. This can be achieved, for example, by the fact that inside the pocket there are protrusions which extend in the longitudinal direction of the female connector and press against the center of the female connector, by which the female connector can be tilted to both sides until it abuts pending. Spring elements in the form of spring tongues within the pocket-shaped holding means press on the lateral edge regions of a spring strip end inserted into the holding means, so that it is held in an untilted position in an unloaded state. This gives an uncovered slatted frame an aesthetically pleasing appearance in that the female slats are all aligned with one another in an untilted position.

The above-mentioned, multiple tilting possibilities ensure that the spring slats optimally adapt to the body contours of a person lying on the bed.

The holding means, in particular those which do not have the aforementioned securing means, can be provided with a depth stop which is designed such that in the unloaded state of the slatted frame the end of the associated strips extends essentially to the depth stop. The slatted frame can therefore be raised on the side edge areas without any significant deflection of the correspondingly shaped support modules taking place upwards.

The edge area element is preferably made in one piece from a thermoplastic. This gives the edge area element the stability necessary for the type of slatted frame present.

An edge region element, which is characterized in that it has essentially pocket-shaped holding means for the end of the at least one female connector and for the end of the supporting bar of a support module, all holding means being arranged next to one another in the longitudinal direction of the longitudinal members of the slatted frame and not in this direction overlap and there is a cover wall bridging all the holding means and designed as a supporting element, which non-positively connects the holding means to one another, can also be used on a slatted frame according to the prior art described in the introduction. Likewise, the connecting element, which is subjected to torsion and bending, and via which the holding means for the support strip is connected to the edge area element, is not on the Limited use together with edge area elements with holding means arranged next to one another.

1 shows a preferred embodiment of the slatted frame in a top view. FIG. 2 comprises a section along the line II-II in FIG. 1 and essentially shows a side view of a support module 7 of the slatted frame. This comprises two or three upper spring strips 3 and a lower support strip 4, which strips extend transversely to longitudinal beams 1, 2, which run below the strips. The mutually facing ends 3a, 4a of all strips 3, 4, which form a support module 7, are held in an edge region element 6.

Along the longitudinal beams 1, 2, which are spaced from one another and usually run parallel to one another, support modules 7 of the type described above are arranged in a row. The spring strips 3 of all support modules 7 lying next to one another thereby form a support surface for a mattress to be placed on the slatted frame.

The support bar 4 of each support module 7 is intended to hold the latter to the side members 1, 2.

The slatted frame design is of the type that the longitudinal beams 1, 2 run below the female slats and are laterally set back from the female slat ends 3a towards the middle of the slatted frame. On the side members 1, 2, depending on the head and foot side of the slatted frame, outwardly projecting feet 71 can be attached or support brackets can be provided which are intended for inserting the slatted frame into a bed frame. In the version with feet, without bed frame, the side members are not visible from the side for an observer and the slatted frame gives the impression of free-floating slats 3, which are limited laterally by the edge area elements 6.

The female connectors 3 are slightly bent upwards in the unloaded state, ie away from the longitudinal beams 1, 2. The opposite the female connectors 3 lower support strip 4 has a concave bend relative to the spring strips 3. In itself, the support bar 4 is wave-shaped. The support bar 4 is essentially divided into three parts. In a central region 8, which extends from the longitudinal member 1 to the longitudinal member 2 and which is designed to be elastically deformable. Adjoining the central area, each support bar 4 has an end area 9, 10, which extends outward from the longitudinal beams 1, 2, the outer end 4a of which faces the ends 3a of the higher spring bars 3 and ends in an edge area element 6. Above the longitudinal beams 1, 2 there are 4 connecting elements or hold-down elements 11 for each support strip, which do not hold the support strip 4 rigidly on the longitudinal beams 1, 2, but hold or hold them down in such a way that length compensation when the support strip or the spring strips spring through relative to the Side members are possible and that a pivoting movement of the support bar in the transverse direction to the side member is possible at each support point of the support bar 4 on the side members 1, 2.

The connection of the support strip 4 with the side members 1, 2, which is specially designed with the hold-down elements 11 in the aforementioned sense, and the elastically deformable central region 8 of the support member 4 ensures that when the spring strips 3 are loaded at the support points of the support member 4 on the side members 1, 2 there is an opposite swiveling movement. That is, with each load on the slatted frame, the edge area elements 6 move downwards on both sides of a support module 7. It is interesting that this is not only the case when the slatted frame is loaded in the center, but that this is also the case when only one edge of the slatted frame is loaded. This prevents the mattress from sloping and the hitherto known tilting effect does not occur.

In order to give the edge region of the slatted frame the necessary stability and not to make the deflection path there excessively large, provision has been made for the two end regions 9, 10 of the support strip to be made less elastically deformable than the central region 8 of the support strip.

In Fig. 2, the arrow 14 indicates a load on only one side edge of the slatted frame. With the arrows 12 and 13 are the Swivel directions at the support points of the support bar 4 on the side members 1 and 2 specified. The arrows 12, 13, 14 also indicate the direction of movement of the edge area elements 6 with increasing load.

In each end region 9, 10 of a support strip 4 there is a limiting member 15, 16 near the outside 17, 18 of each side member 1, 2. The left and right delimiting members 15, 16 extend downward on the outer sides of the longitudinal members over a certain sub-area of the latter, with a stop surface being formed on each delimiting member, which runs parallel to the outside of the corresponding longitudinal member 1, 2. In the unloaded state of the corresponding support module 7, a space 19, 20 is provided between the abutment surface of the limiting members 15, 16 and the outer sides 17, 18 of the side members 1, 2. When the corresponding support module 7 is loaded, the limiting members 15, 16 move with their abutment surfaces as a result of the previously described pivoting of the support strip supports against the outer sides 17, 18 of the side members 1, 2 and, after a certain spring deflection of the spring strips 3 and the edge area elements 6, come on Outside of the side members 1, 2 for contact. Since a further pivoting of the support bar 4 around its support points is no longer possible, the deflection path is thereby limited. Depending on the size of the selected intermediate space 19, 20, the deflection path, in particular the edge area elements 6, can be larger or smaller.

Fastening devices are provided on the edge region element 6 so that bracket end parts, connecting parts or other parts can be fastened thereon. In the embodiment shown there are, for example, holding brackets 68 which prevent a mattress lying on the slatted frame from sliding sideways.

With the reference numeral 69 head and foot brackets are identified, by which a longitudinal displacement of a mattress on the slatted frame can be prevented.

In Fig. 3, a support point of the support bar 4 on one of the side members, in the example shown on the right side member 2, is shown enlarged. FIG. 4 shows a view of this point from the direction of the arrow labeled IV in FIG. 3. 5 shows a perspective view of the hold-down element 11, which plays a central role in connecting the support strip 4 to the side members. 3, 4 and 5 are therefore described simultaneously below.

In Fig. 3, the right side member 2 is shown in section. A partial area of the support strip 4 is drawn above, the aforementioned central area 8 being to the left of the side member 2 and the end region 10 of the support bar 4 extending to the right of the side member 2. In the example shown, the support strip 4 is made in one piece as a plastic injection-molded part and in particular comprises an upper rib 46 which extends continuously from the end of the support strip to the end of the support strip and an essentially parallel and spaced lower rib 45, the two ribs along their entire length by means of a central web 47 are interconnected. The cross section of the support bar 4 is thereby essentially H-shaped. Additional reinforcing ribs 48 running in the vertical direction ensure the necessary stability. There are no reinforcing ribs 48 in the central region 8, which is more elastically deformable than the end regions 9 and 10. In the end areas 9 and 10, however, a relatively large number. As a result, the elastic deformability of the end regions 9, 10 relative to the central region 8 is smaller. The limiting member 16 visible in FIG. 3, which extends downward on the outside of the longitudinal beam 2, is integrated in the support strip 4 which is produced in one piece. The space 20 between the outer side 18 of the longitudinal beam 2 and the stop surface of the delimiting member 16 running parallel to it is very nice to see.

A connecting element or hold-down element designated 11 comprises a carrier 26, on which a support element 25, two hold-down slides 42, an adjusting member 21 and a cover 50 are arranged. The carrier 26 is essentially a U-shaped part with a longer leg 28 which extends on the outside 18 to the side member and a shorter stop leg 29 which is on the inside of the side member 2 extends. A preferably rectangular lead-through and holding opening 27 is provided in the base leg, which connects the two legs mentioned and extends in the region of the support strip 4 over the top 22, 23 of the side members 1, 2. The support element 25 made of an elastic material such as rubber, silicone or the like is guided and held through this opening. On the side facing the side member 2, the support element 25 has a plate-shaped support. The side of the support element 25 protruding upward from the lead-through opening 27 comprises a surface 37 that is cambered transversely to the longitudinal beam 2 and into which a notch 35 running in the longitudinal direction of the longitudinal beam 2 is embedded. The notch is essentially triangular in cross section. On the support bar 4 in the area of the upper sides 22, 23 of the two longitudinal beams 1, 2 there is a support lug 24 which projects into the notch 35 just mentioned when the support bar 4 is mounted. The carrier 26 is screwed to the side member 2 by means of screws which are guided through fastening eyes 30 on the fastening flange 28.

It is now important to hold down the support bar 4 placed on the support element 25. For this purpose, the carrier 26 in the longitudinal direction of the longitudinal carrier 2 each has a guide part 44, each following the passage opening 35, on which a dovetail-shaped sliding guide is formed. One of the hold-down slides 42 can be pushed along the dovetail-shaped slide guide over the guide part 44 and advanced against the support bar 4. Facing this, each hold-down slide 42 has a hold-down lug 43 which can be pushed over the lower rib 45 of the support bar 4 and thereby holds the support bar 4 down on the cambered surface 37 of the support element 25.

Latching means 49 are arranged along the dovetail-shaped sliding guide both on the guide part 44 and on the hold-down slide 42, which only allow the hold-down slide to be moved along the guide part step by step with the application of a certain displacement force. The latching means 49 serve to prevent the slider 42 holding down a support strip from being able to remove itself from its advanced stopping position. The locking means 49 are preferably such trained that the push-on force is less than the pull-off force. This can be achieved by means of an appropriately shaped toothing.

A cover 50 made of an elastic material, such as rubber, silicone or the like, extends essentially in the shape of a truncated pyramid over the base leg of the carrier 26, the hold-down slide 42 and the held-down region of the support strip 4. The cover 50 is attached to retaining lugs 51 which are on the base leg of the Carrier 26 are arranged, held and, in addition to the purely covering task, the further task of limiting the travel of extremely strongly sprung spring bars relatively softly and noiselessly. The cover is a stop means 50 for the female connectors 3.

A guide slot 31 is arranged in the fastening leg 28 of the carrier 26 and extends essentially from the free leg end against the support strip 4. Snap-in extensions 32 are provided along the guide slot 31 at a periodic distance. The end region of the guide slot 31 facing the free end of the leg 28 is expanded in a rectangular manner, a rectangular opening which has been created thereby serving to insert a guide block 38 of the adjusting member 21 into the guide slot 31. A web 33 remaining at the end of the leg 28 serves as an end stop, so that the adjusting member cannot be pulled down out of the guide slot 31. The guide block 38 slides along the guide slot 31 in a recess 52 which has been worked into the leg from the surface lying on the outside 18 of the longitudinal beam 2. In addition, on the outside of the leg 28 facing away from the outside 18 of the longitudinal member 2 there are two guide ribs 40 for the setting element 21, which are provided with an inhibiting toothing 41 to prevent an independent adjustment of the setting element 21 once set.

The adjusting member 21 is essentially a plate-shaped structure that can be pushed along the guide slot 31 into the intermediate space 20 between the limiting member 16 and the side member 2. This allows the space 20 or the pivoting path of the limiting member be limited. Advantageously, provision is now made for the adjusting member 21 to be essentially wedge-shaped, the pivoting path decreasing as the adjusting member is increasingly driven into the intermediate space 20. An advantageous embodiment of the adjusting member 21 is given in that, instead of a wedge shape, a three-stage version with adjustment stages 39a, 39b and 39c is selected with increasing step height. The snap-in extensions 32 in the guide slot are then spaced apart from one another in such a way that there are three defined positions for the setting member 21. The spring deflection of the edge area elements of the slatted frame can thus be set or changed from large to medium to small, depending on the insertion width of the setting member, and adapted to the needs of the person for whom the slatted frame is intended. The adjustment element can be made of an elastic material, such as rubber, silicone or the like, in order not to achieve an abrupt, but rather a soft, noiseless limitation of the deflection path.

6 and 7, the edge area element 6 is shown, with which the lateral ends 3a, 4a of all spring strips 3 and the support strip 4, which form a support module 7, are combined. The edge area element 6 is designed such that a holding means 56 for the end 4a of the support strip 4 and a holding means 55 for the end 3a of a spring strip 3 are provided. The support strip 4 and two spring strips 3, one on the left and one on the right of the support strip, are preferably combined in an edge region element. The holding means 55, 56 do not overlap in the longitudinal direction of the edge region element 6, as a result of which the element is relatively elongated, but appears low and slim.

In particular, for the head-side and foot-side end of the slatted frame, it can be provided that edge area elements are designed in such a way that holding means 55 for two slats 3 are provided on one side of the support strip 4, ie on the side facing the slatted frame end. Such an embodiment of an edge area element 6 is indicated by dash-dotted lines in FIGS. 6 and 7.

The holding means 55, 56 for the female connector 3 and the supporting bar 4 are preferably pocket-shaped and completely encompass the end 3a of a female connector 3 and the end 4a of the supporting bar 4. All holding pockets 55, 56 are non-positively connected to a support element which is designed as a top wall 57. The top wall 57, which encompasses the side areas and the top side of a support module in its edge area, is supplemented with a side wall 70 on the end face facing away from the strips 3, 4. In this way, the edge area element 6 acts for a viewer as being closed on all sides to the outside.

In the type of slatted frame shown, the edge area element 6 is only pushed over the ends 3a, 4a of the spring strips 3 and the support strip 4. It has no connection to a side member or frame. This must ensure that the edge area element 6 cannot slide laterally by itself. It is provided to provide at least one holding means 55, 56 and the bar assigned to one of these holding means with securing means 58, 59, preferably a type of snap device, so that after the edge area element 6 has been plugged onto the bar ends 3a, 4a, it does not automatically slide sideways is more possible. For this purpose, the holding means 56 and the end 4a of the support strip 4 have preferably been provided. The holding means 56 has a first securing means in the form of at least one rib 59 which projects into the pocket and extends transversely to the pocket, and the end 4a of the support strip has a second securing means in the form of a notch 58 which extends in such a way that when inserting the end 4a of the support strip 4 into the pocket 56, the rib 59 engages in the notch 58 and thereby prevents the edge region element 6 from sliding off independently of the strip ends 3a, 4a.

A fastening device in the form of an eye for receiving a screw thread of a screw is shown at 67, to which the aforementioned end part 68 can be fastened, for example. The holding pockets 55 for the female connectors 3 have a depth stop 64. The spring slats used extend practically to the depth stop when the slatted frame is unloaded. When lifting the slatted frame on the edge area element, the spring slats, which are bent slightly upwards, experience an elongation and thus an increase in length. They are in contact with the depth stop 64 and thus make a substantial deflection of the edge region element 6 upward impossible.

The holding element 56 for the support bar 4 also has a depth stop 65. However, the end of the support strip 4 is already held in place with the securing means 58, 59 mentioned and prevented from longitudinal displacement.

8 shows that the edge area element 6 and thus the spring strips 3 held therein are designed to be pivotable relative to the holding pocket 56 with the support strip 4. An essentially circular segment-shaped pivot stop 66 is arranged between the top wall 57 and the pocket side of the holding means 56 facing this top wall. It is intended to define the aforementioned pivoting movement in that the side of the holding means 56 which bears against the pivoting stop rolls along the pivoting stop 66 when the edge region element 6 is tilted.

The fastening of the holding means 56 to the top wall 57 or to the side wall 70 is shown in FIG. 9. The holding pocket 56 is connected to the side wall 70 by a connecting element 60 which can be subjected to torsion and bending. The connecting member 60 is preferably a relatively thin-walled tongue that extends between the holding pocket 56 and the side wall 70. It can be seen from FIG. 9 that thanks to this tongue, which is relatively elastic, the pivoting movement shown in FIG. 8 can be carried out. In addition, however, the longitudinal direction of the holding pocket 56 can also be changed relative to the top wall 57 in that it can be bent downward in the direction of the arrow 72. Depending on the deflection of a support module 7, the relative longitudinal directions of the ends 3a of the female connectors 3 and the end 4a of the supporting bar 4 can change relative to one another.

Each holding pocket 55 for one of the ends 3a of a female connector 3 is designed such that a limited tilting of the female connector transversely to it Longitudinal axis in the holding pocket 55 is possible. For this purpose, the cross section of the holding pocket is made larger than the cross section of the female connector end. An upper projection 61 and a lower projection 62, which extend in the longitudinal direction of the female connector and then extend in the longitudinal direction of the female connector and lie essentially centrally on the female connector end 3a, are then present in the holding pocket. The lower projection 62 is essentially in the form of a V with a large opening angle, the two legs of the V on the one hand and the top wall 57 on the other hand serving as a limitation for the tilting movement of the female connector 3 within the holding means 55.

Spring means 63 within the holding pocket 55 in the form of two spring tongues, each of which acts laterally on the longitudinal axis of a female connector 3 on the female connector end 3a, ensure that when the slatted frame is not loaded, the female connectors 3 lie next to one another in an aligned, untilted state.

The edge area element 6 is preferably made in one piece from a thermoplastic plastic as an injection molded part.

Both the design of the support strip 4, its bearing on the longitudinal beams 1, 2 and the design of the edge area element 6, each part for itself, in a certain proportion, contribute to the solution of the task set forth.
