Description

The invention relates to a unit for supporting at least one end of a bar on a grate bar according to the preamble of claim 1.

Such a unit is in the DE 43 32 704 A1 described. With such a unit can produce slats, in which the different slats in one and the same plane, the bed are arranged.

Some users want different hardnesses at different locations of a lying surface. It is therefore known to attach slats in selected areas of the bed surface on special units on the longitudinal grille bars, which z. B. offset from each other bolts that engage in blind holes of the spar. There are also known vertically adjustable fittings, which in turn comprise two mutually displaceable fitting parts, which are biased by a spring in an extended position. Such a fitting element is z. B. in the DE 85 31 920 U described.

A known fitting element, which is used for local contouring of the lying surface (usually a lowering) is a separate component, which requires additional space in rust transverse direction.

Is in an already finished slatted therefore in a certain rust area a lowering of the bed desired, so the slats must be shortened when using the known adjustment fitting. Also, elastomeric bearing elements that have been used previously can not be used in the area of Liegeflächenkontorierung.

By means of the present invention, a possibility is to be indicated of how, in selected areas of a conventional slatted frame, using the same layer elements which are also used in the main sections of the lying area, a local lowering and / or raising of the lying area can be achieved.

This object is achieved by a unit having the features specified in claim 1.

In the unit according to the invention can be adjusted by simply reacting the holding member, the support elements in the vertical direction, which cooperate with the slats-bearing element.

Advantageous development of the invention are the subject of dependent claims.

With the development of the invention according to claim 2, a large local height difference is obtained in the position of the slats between two working positions of the holding part. In the first working position, the second support elements are located above the first support element, in the second work position below the first support element.

With the development of the invention according to claim 3, it is possible, the two working positions of To specify holding parts so that the slats are in their upper position farther away from the main lying surface than in their lower position or vice versa.

The development of the invention according to claim 4 makes it possible to use bearing elements which are suitable for the storage of two bar ends. This facilitates the mounting of the frame.

The development of the invention according to claim 5 is in view of the symmetry of the holding part and the implementation of the holding member between its two working positions of advantage.

In a unit according to claim 6, one has in the extension part a further possibility of influencing the overall spring characteristic of the unit. If the extension part made of substantially rigid material, so it represents a stop for beams of a spring truss, which belongs to the elastomeric bearing element. About the size and shape of the extension part, this stop action can be controlled.

In a unit according to claim 7, the An .. effect not only by the shape of the designer, but also by adjusting the extension part on a hub adjustable.

In a unit according to claim 8, the extension part is an elastomeric block spring, which allows to influence the overall spring behavior of the unit on the geometry and type of the elastomeric material.

The development of the invention according to claim 9 allows adjustment of the contribution of the rubber block spring to the overall spring characteristic of the unit still by the user.

With the development of the invention according to claim 10 ensures that a spring framework of an elastomeric bearing element at least partially resilient in both working positions of the holding part.

The development of the invention according to claim 11 is in view of smooth boundary surfaces of the holding member and easy handling of the same advantage.

The development of the invention according to claim 12 is in terms of simple and inexpensive production of the holding part of advantage.

A unit according to claim 13 is in view of the simple and secure connection of a holding member with the Rostholm advantage.

In this case, it allows the development of the invention according to claim 14, even for a single lath to bring about a change in level of the slat surface, since the holding part is connected against rotation with the Rostholm.

FIG. 11

a similar view as FIG. 11 in which a modified position-body-holding part is shown.

It will be initially on the FIGS. 1 to 6 Referenced.

FIG. 6 shows a portion of a grate longitudinal spar 10 of a slatted frame in which blind holes 12 are drilled at regular intervals.

How out FIG. 5 can be seen, 12 connecting pins 14 are fitted into the blind holes, which have a cooperating with the blind bore 12 pin portion 16, a stop flange 18 and a protruding front pin portion 20.

In FIG. 4 is after the arrangement FIG. 5 a total of 22 designated holding part mounted.

This comprises an extension pin 24 which has a cylindrical chamber 26 which is open towards the spar side surface and which can receive an associated connecting pin 20 in a frictional or interference fit.

The extension pins 24 sit at the two lower corners of a rectangular support plate 28. At the upper ends of the support plate 28 sit second support pins 30 which have the smaller diameter than the extension pin 24th

In FIG. 3 is on the arrangement of FIG. 4 a total of 32 designated bearing body mounted.

This includes a lower base beam 34, in which cylindrical recesses 36 are provided, whose diameter and spacing is selected so that the two recesses 36 are slidable over the two second trunnions 30. Between the recesses 36 and the support pin 30 prevail Reibsitz- or press-fit relationships.

In the base bar 34, a substantially rectangular recess 38 is provided between the two recesses 36. This can serve, if necessary, to connect the end of a third bar to the bearing body 32.

Incidentally, the bearing body 32 has two outer convex curved beams 40 and two acute angle converging inner beams 42, 44, as shown in the drawing. The tops of the beams 40 and 44 support bearing caps 46, each of which has a lath receptacle 48.

The two bearing caps 46 are connected by a web 50.

The bearing body 32 is a one-piece molded part made of elastomeric material and represents a vertically springing and twistable elastomeric spring.

In FIG. 1 illustrated that in the two slats 48 each one end of two slats 52, 54 is inserted.

Figure 2 shows the arrangement after FIG. 1 seen in Rostlängsrichtung. It can be seen that the extension pin 24 protrudes axially beyond the end face of the bearing body 32.

The extension pin 24 has no function for the spring behavior of the bearing unit in the unit described so far. Instead of connecting pins 14 in combination with extension pins 24, it would also be possible simply to use only one connecting pin 14 integrally formed on the retaining plate 28.

As can be seen from the drawing, the holding part 22 is symmetrical to a transverse center plane which is perpendicular to the axis of the grate longitudinal spar 10 and
lies between the two extension pin 24. At the same center plane and the bearing body 32 is symmetrical when it is placed on the trunnions 30.

The diameter of the support pin 30 is selected so that it corresponds to the diameter of the connecting pin 20. One can thus place the bearing body 32 directly on the connecting pin 20 or put on the support pin 30. In the latter position, the tops of the slats 52, 54 are then a distance above the tops of such slats, which are held by bearing directly on the connecting pin 20 bearing bodies 32, which corresponds to the center distance between the support pin 30 and the extension pin 24.

The position of the upper sides of the slats 52, 54 can now be specified differently again by placing the holding part 22 on the connecting pins 20 in such a way that the supporting pins 30 lie below the extension pins 24.

This is in FIG. 7 shown. In this position then sits on the support pin 30 plugged bearing body 32 as in FIG. 8 shown.

In this position, the extension pins 24 engage under play through the partially oval spaces 38, which are bounded by the beams 42, 44. Thus, the bearing body 32 can deflect so far until the interconnected upper ends of the beams 40 and 44 come into contact with the top of the trunnion 24.

FIG. 9 shows the arrangement after FIG. 8 However, in the bearing caps 46, the ends of the slats 52, 54 are used again.

FIG. 10 shows the arrangement after FIG. 9 seen from the right there. It can be seen again that the extension pins 24 protrude axially beyond the framework of the bearing body 32.

A modification of the invention is in FIG. 8 dashed lines.

The connecting pin 20 has now reduced diameter, and on it an extension part 56 is attached, which is made of elastomeric material.

The fit between the extension part 56 and the connection pin 20 is such that the extension part 56 can be rotated on the connection pin 20 while overcoming the frictional engagement. Alternatively, one can make the connecting pin 20 and a cooperating with him recording 58 of the connecting part 56 also polygonal, so that the extension member 56 can be attached to the connecting pin 20 in the predetermined discrete different angular positions.

By rotating the eccentrically mounted connecting part 56 can thus pretend when compressing the elastomeric material of the extension member 56, the compression of the bearing body 32 can be made only by additional overcoming elastic resistance. By turning the extension part 56 but at the same time the volume of that part of the extension part 56 is reduced, which is active as a block spring.

In a further modification of the invention, which is not shown in the drawings, one can also provide a storage unit for only a single lath. In this case, the blind bore 12 is then formed polygonal or otherwise out of round, and the connecting pin 14 receives a complementary non-circular cross-sectional geometry. The retaining gap 28 can then be limited to a narrow strip of material that connects the support pin 24 with the support pin 30.

Alternatively, one can also ensure the rotation of only responsible for a lath holding member 22 by providing an additional pin on the spar side surface of the holding gap 28, which is spaced from the connecting pin 14 and with an associated additional blind hole of the longitudinal rail spar (not shown).

The holding parts 32 are one-piece injection molded parts made of thermoplastic material. They can thus be produced inexpensively. If one chooses the diameter of the extension pin 24 equal to the diameter of the support pin 30 (in one piece part possible), you can thus designing the entire grid using this single inexpensive molded part so that the local bed area corresponds to a normal average bed, a local bed or a local bed. This contouring can be done by the user according to his specific needs. The slats and the bearing bodies can be the same in all areas of the slatted frame.

If desired, one may either prefer an upper portion of the longitudinal rail spar 10 towards the outside of the bearing body 32, as in FIG FIG. 10 shown in dashed lines, or conversely, the outer surface of the bearing body 32 to pull in the immediate vicinity of the inner surface of the Rostlängsholmes 10, as in FIG. 2 shown in dashed lines. In both cases, then the gap between the outer surface of the bearing body 32 and the inner surface of the grate longitudinal spar 10 is reduced.

It will be appreciated that the principle described above can also be extended to holding parts comprising more than two sets of extension pins 24, 30.

For transition areas between raised (or lowered) sections of the lying surface and normal sections of the lying surface can also provide holding parts, in which the two trunnions 30 are at different heights, as in FIG. 11 shown.
