Description

The invention relates to a slatted frame with a plurality of mounting bodies for mounting spring strips according to the preamble of claim 1.

Such slatted frame is with the subject of EP 1 425 995 B1 ( DE 602 10 992 D2 ) known.

The mounting body shown there consists essentially of a on the longitudinal side of the longitudinal spar of a slatted frame to be fastened plastic body on which a spring body is arranged plugged.

The spring body forms two adjacent insertion pockets for receiving the free ends of spring strips. Each spring bar is inserted with its free end in each case a slide-in pocket. The insertion pockets are present in pairs and are each formed on an underlying spring body, each spring body consists of approximately barrel-shaped hollow springs made of plastic, which are connected to the mounting body.

The cited document has the aim to ensure the greatest possible travel for the deflection of the spring body and arranged on the spring body insertion pockets for the attitude of the spring strips.

This is to ensure an optimally long suspension travel when compressing the spring strips in the direction of the longitudinal spar of the slatted frame. The document solves the problem in that between the spring bodies, a relatively large space is formed which is bounded at the bottom only by a mounting body side, extending in the axial direction upwards holding device.

When the spring strips are loaded with the maximum compression pressure, the spring bodies are compressed in parallel under the development of a counterforce, until a middle connection plate between the pockets on the top of the assembly side stop body hits.

This concept has the disadvantage that tilting or tilting of the spring body of the entire spring structure tilted and the maximum compression travel is no longer given. If therefore the spring strips do not spring parallel, but a transverse force acts on the spring strips, it comes to stop on the side surfaces of the central recess.

It comes to an already lying before stop, whereby the axially possible spring travel of the spring body is greatly shortened and the spring bodies are damaged.

Another disadvantage of the known construction is that the mounting body side stop at the same time forms a height-adjustable mounting device for mounting the mounting body on the longitudinal side of the longitudinal spar, and therefore has a considerable axial height, so that the upper side arranged stop surface far into the movement space of the spring body engages and thus the axial travel is severely limited.

The invention is therefore based on the object, a slatted base with a variety of mounting bodies for mounting spring strips according to the preamble of the current claim 1 so that a greater axial travel can be assigned to the spring bodies, and the risk of damaging the spring body at canting Female connector is avoided.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

Feature of the invention is that the stop limit is no longer between a connecting member between the pockets and a axially extending upward mounting body, but that according to the invention the stop limit is formed to limit the deflection of the spring body from a längsholmseitig fixed stop bar, the at the bottom of a stop plate can be brought to the stop, which is connected to the insertion pockets.

The stop surface on the mounting body according to the prior art is inventively replaced by an arranged on the longitudinal spar stop surface, which is inventively designed as a stop bar.

This results in the advantage of an extended axial spring travel, because no extending in the axial direction upwardly extending body with a stop surface in the spring travel of the spring body into it.

Rather, the spring body can spring freely down, and the deflection is limited only by the bottom of stop plates, which are attached to the top of the pockets.

In a preferred embodiment of the invention, it is provided that the stop plates form a material-integral plastic part at least with the insertion pockets for the holder of the spring strips.

In a further embodiment of this invention idea is further proposed that the insertion pockets forms a material integral plastic part with the underlying spring bodies, so that a total of the thus formed holding body consists of at least a total of three parts, namely the stop plate, arranged below the insertion pocket and one or more arranged underneath spring bodies.

In a preferred embodiment of the invention, it is provided that the arrangement of a holding body is formed in pairs. This means that two mutually parallel and spaced apart stop plates are connected to underlying insertion pockets, wherein between the two stop plates and the underlying insertion pockets a horizontal distance is formed.

Further, it is preferred if each insertion pocket is connected to an underlying, arranged centrally to the insertion pocket first spring body, and this respective spring body are each laterally formed on a central, both spring body, wider spring body.

This results in a holding body, which is formed of pairs (double) to each other arranged stop plates and underlying insertion pockets, each insertion pocket is supported on an underlying spring body, and each of these spring body is supported on a centrally disposed further spring body.

According to the invention instead of a arranged in the interior of the spring body stop element, as it DE 602 10 992 D2 proposes, now provided a longitudinal spar stop limit. In a preferred embodiment of the invention, it is therefore provided that the underside of the stop plates, which are integrally formed on the insertion pockets, can be brought to bear against a longitudinal spar-mounted stop strip.

The maximum deflection of the spring body is thus limited by longitudinal spar side stops.

In a preferred embodiment of the invention, it is provided that the längsholmseitige stop limit is formed from a stop bar whose length corresponds approximately to the width of the stop plates, so even with a tilting of the spring body, when acting on the mutually parallel spring strips a tilting force, always ensured is that at least one surface of the stop plate comes to rest on the longitudinal spar-side stop plate.

Thus, the axially possible spring travel over the prior art is substantially expanded because the stop limiting, omitted in the spring body stops omitted and now only longitudinal rail side stops are used.

It is preferred if the stop bar is arranged on the upper side of the longitudinal spar side attachable mounting body. The attachment may consist in a first embodiment in that the stop bar with the holder on the longitudinal beam forms a material made of plastic material einstückiges part.

In one embodiment of the invention, it is preferred if the stop bar is connected in the manner of a plug connection with the mounting body. In this way, the stop bar is easily replaceable held on the mounting body. This is the first time the possibility of adjusting the suspension travel. It can thus be exchanged for a stop bar with a second height a stop bar with a first height to create different high stop limits at different points of the slatted base.

It is further preferred if the holding body consisting of the spring bodies and the stop plates and the insertion pockets can be plugged onto the longitudinal spar-side mounting body. In this way, a highly resilient connection results without unwanted stop limitations in the spring travel of the holding body are present.

Furthermore, it is preferred if the longitudinal spar-side mounting body is slidably received in an undercut longitudinal groove of the longitudinal spar. The displacement length of the respective mounting body can be read on a scale fixed to the mounting body, which is displaceable with respect to a längsholmseitigen, fixed marking together with the mounting body.

It is particularly advantageous if the stop plates, which form the upper boundary of the holding body, in the direction perpendicular to the longitudinal extent of the longitudinal spar, upwardly deflecting Abweisfläche to better storage of resting on the spring strips and the stop plates mattress protector or a To ensure mattress.

The invention is not limited to the paired arrangement of stop plates, arranged below insertion pockets and arranged below spring bodies.

In a simple embodiment of the invention, it is merely provided that a single stop plate is connected to a spring body arranged centrally underneath and in turn connected to another spring body, wherein the lower spring body is releasably connected to the längsholmseitigen mounting body in the manner of a connector.

In addition to the simple design with a stop plate, a spring body and another spring body arranged underneath, a paired arrangement is described and claimed.

In this paired arrangement, the paired stop plates are mounted parallel and spaced apart on two mutually parallel and spaced apart insertion pockets, and the insertion pockets are in turn formed on the top of two parallel spring bodies, wherein the two spring bodies formed centrally on a lower, central spring body are, in turn, attachable to the mounting body or releasably connected in another way.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are the drawings and its description further features essential to the invention and advantages of the invention.

In FIG. 1 is the right side of a slatted frame 1 shown in an explosive representation, in the longitudinal groove 13 a längsholmseitiger mounting body 12 is fixed, which is also displaceable and lockable along a certain displacement along the longitudinal groove 13.

The displacement path of the mounting body 12 is read on a scale 14, which is displaceable relative to a longitudinal beam side fixed mark 34 together with the mounting body 12.

On the mounting body 12 is a stop bar 11 in the manner of a connector fastened. For this purpose, the stop bar is formed as an elongated, profiled plastic element which forms an upper stop surface 17. The underside of the stop bar 11 is formed as a recess 21, the rear, a rear stop surface 23rd forms, in the area of a forward-facing plug-in rib 19 is formed. The stop bar 11 is shown in FIG FIG. 5 inserted into an associated recess at the top of the longitudinal spar-side mounting body 12, and the front inclined surface 20 then forms an approximately flush transition to the mounting body side inclined surface 31 (see FIG. 5 ).

The only in FIG. 5 dashed lines shown female connectors 33 are each inserted with their free ends in associated insertion pockets 7, 8 of a holding body 3 and are releasably held there.

The upper side of each insertion pocket is formed by a stop plate 9, 10, which is in each case materially connected in one piece to the insertion pocket 7, 8.

Between the stop plates 9, 10 results in a horizontal distance, as in FIG. 1 shown.

Below each stop plate 9, 10, a first pair of spring bodies 5, 6 is arranged, which are also material integrally connected to the insertion pocket 7, 8, and each pair of existing spring body 5, 6 is formed on a central spring body 4, so that the entire holding body is designed as a multiply sprung part.

The holding body 3 is attached to the attached to the longitudinal spar 2 mounting body 12, as will be explained later.

The FIG. 2 shows the end view of the arrangement in the direction of arrow II in FIG. 1 , And it can be seen that a very large compression travel of the insertion pockets 7, 8 is given in the direction of arrow 15 down in the direction of the longitudinal spar 2, because the central region 32 between the two spring bodies 5, 6 is not reduced by axially upwardly directed internals as shown in the prior art.

It is also shown that the insertion pockets 7, 8 are connected by a respective connecting piece 16 with the underlying spring bodies 5, 6.

Furthermore, provision may be made for the stop plates 9, 10 to be connected to one another by a top connecting element which centrally connects the stop plates and covers approximately the center region 32.

In the embodiment shown, however, this connecting element is omitted, and the stop plates 9, 10 are completely independent of each other on the associated spring bodies 5, 6 resiliently mounted.

The FIG. 3 now shows the maximum deflection of the stop plates 9, 10 at maximum load of the inserted into the pockets 7, 8 spring strips 33rd

In the maximum load case shown thus suggests the bottom of the respective stop plate 9, 10 at the top of a mounting body side stop bar 11.

This is also in FIG. 4 shown.

The FIG. 5 shows the unloaded state, where it can be seen that the respective bottom of the respective stop plate 9, 10 forms a lower stop surface 25, in the direction of arrow 15 overcoming the spring capacity of the spring body 4, 5, 6 can be brought to rest on a mounting body side releasably secured stop bar 11 is. For this purpose, the top of the stop bar 11 is formed as a stop surface 17.

It can be provided that the stop bar 11 is made of a particularly flexible and soft material, so that the stop of the stop plates 9, 10 with the stop surface 25 on the stop surface 17 of the stop bar 11 is particularly cushioned and damped.

The FIG. 5 shows that the entire holding body 3 has inwardly directed cams 28 which can be inserted into associated slots 27 on the outside of the mounting body 12.

It is also out Figures 5 and 6 recognizable that the mounting body 12 is itself connected to a lug 29 which engages in the undercut longitudinal groove 13 in the longitudinal beam 2 of the slatted frame 1. In this way, the entire mounting body 12 is perpendicular to the plane of the Figures 5 and 6 slidably formed by the longitudinal beam 2.

The top of the stop plates 9, 10 forms a deflecting surface 18 which is inclined obliquely upwards.

The top of the mounting body 12 is chamfered and forms an upper part 30, in the region of which an inclined surface 31 is arranged, which is approximately aligned with the associated, overlying inclined surface 20 of the stop bar 11 according to the invention.

Thus, the top of the mounting body 12 forms a receiving space 24 for the local, releasable attachment of the stop bar 11, which is equipped with a projecting plug-in rib 19 which is insertable into an associated receiving opening in the upper part 30 of the mounting body 12.

The stop bar is limited at the rear end by an axially upstanding projection 35 of the mounting body 12.

The holding body 3 is according to Figures 5 and 6 with its directed against the longitudinal beam 2 cams 28 plugged into associated slots 27 on the mounting body 12, wherein the slot 27 are separated by a slot dividing projection 26 of the mounting body 12 from each other. In this way, a highly resilient, protected against tilting Aufsteckverbindung between the holder body 3 and the longitudinal spar-side mounting body 12, so that high spring forces in the direction of arrow 15 of the spring strips 33, overcoming the spring force of the spring body 4-6 in the direction of the längsholmseitigen mounting body 12th can be transmitted. This results in an optimally large travel 36, as in FIG. 5 located.

After the stop bar 11 is interchangeable, accordingly, the maximum deflection 37 (see FIG. 6 ) Can be changed by selecting the height of the stop bar 11.
