Description

The present invention relates to a rolling grate for supporting a mattress or the like with a plurality of the grid in the transverse direction spanning, in the longitudinal direction of the grate one behind the other arranged carriers, a plurality of arranged on the carriers, resilient individual support elements whose upper support surfaces together form the support surface of the grate, and between each two adjacent carriers arranged connecting means for up and ausrollbaren holding together the carrier.

Roller grates are already known as conventional slatted frames. The slats are connected to each other via tapes, which ensure a cohesion of the slats and specify the maximum distance of the slats in the unrolled state.

A roll bar according to the preamble of claim 1 is for example off DE 10 2009 055 782 A1 known.

In roller grates of the type mentioned above, there is the problem that the carrier tilt at non-central load of the individual support elements, since the carrier receive a torque about its longitudinal axis.

The invention has for its object to solve this problem.

This object is achieved in that the carriers are each provided with at least one support member or rigidly connected, which has an extension in the longitudinal direction of the grate, which is at least as large as that of the support surface of the individual support elements arranged on the carriers. The longitudinal extension of the support parts is preferably larger, in particular slightly larger, than that of the individual support elements.

Through these support parts tilting of the carrier is prevented even with a non-central load of the individual support elements. The support by the rolling shutter according to the invention is thereby improved over known rolling grates with individual support elements.

By providing support members at both ends of the carrier, a particularly high Kippfestigkeit the carrier can be achieved. In principle, however, only one support member could be provided, for example, in the middle of the carrier, in particular when the rolling grate is provided for support on a plate.

According to a particularly preferred embodiment of the invention, the support members at the same time form the connecting means of the carrier by the support members of adjacent carriers are each connected to each other in the up and Ausrollrichtung movable. Separate lanyards are thus unnecessary. The support parts fulfill a beneficial dual function.

The support members can be connected to each other via one joint, hinge or flexible or elastic band. A connection via a band is particularly cost-effective.

According to a particularly preferred embodiment of the invention, the support members are formed as rods, which are each connected to one end of an associated carrier T-shaped. Thus, a good and symmetrical support of the carrier against tilting can be achieved. According to another embodiment of the invention, the support members of adjacent carriers are formed together by a flexible, in particular elastic rod, in particular all in the longitudinal direction of the rolling grate successively arranged support members as a rod. Unlike the connecting straps conventional rolling grates, such a rod is not compressible and therefore also ensures increased resistance to tipping for the wearer.

According to a further embodiment of the invention, stops are formed on the support parts, by which the Aufrollradius is limited. This can be prevented that the individual support elements are damaged by the minimum rolling radius is chosen so that the individual support elements not or only slightly come into contact with each other.

According to a likewise preferred embodiment of the invention, the support members are made of wood. This is particularly favorable to manufacture because no molds are needed. The support members may also be made of plastic or other material.

According to a further preferred embodiment of the invention, the rolling shutter is provided with an erectable head and / or foot part, which is connected via at least one support member articulated to the rolling grate. The support parts is thereby assigned a further function that can not be provided in known rolling grates, since there are no running in the longitudinal direction of the rolling shutter rigid elements.

According to another embodiment of the invention, the rolling grate is designed to roll up in one direction only. This can be realized, for example, by virtue of the fact that the support parts are connected to one another via knee-joint-like hinges are connected. This embodiment has the advantage that a retraction direction can be fixed, in particular such that the individual support elements are inside. In addition, the lying property of the rolled-out roll grille is thereby improved.

Embodiments of the invention are illustrated in the drawings and will be described below. They show, in each case in a schematic representation,

The in Figure 1-3 shown roller grate comprises a plurality of the grid in the transverse direction spanning, in the longitudinal direction I of the grate one behind the other arranged carriers 1 and a plurality of arranged on the carriers 1, resilient single support elements 2, the upper support surfaces 3 together the support surface of the grate for supporting a mattress or the like form. The carriers 1 are connected at their two ends in each case with a rod 4, whose extension in the longitudinal direction I of the grate is greater than the longitudinal extension of the support surfaces 3 of the individual support elements 2. The rods 4 can be supported on a longitudinal spar of a bed base or other support and thereby prevent tilting of the carrier 1 at non-central load of the single support element. 2

The bars 4 adjacent carrier 1 are each connected via a knee joint 5 movable together. The knee joint 5 is arranged such that each rod 4 can be pivoted relative to its adjacent rod 4 only upwards. The roll bar can therefore only in the in the Figures 4-6 be rolled up as shown. In the opposite direction, however, a pivoting of the rods 4 against each other is blocked by the knee joint 5. In the unrolled state, the roll grille fits in a package 6 of, for example, 60x60 cm.

The rods 4 are like the carrier 1, for example made of wood. They can be produced inexpensively and connected in a simple manner with the bars 1, for example by gluing and / or nesting. In principle, however, the rods 4 can also consist of a different material, for example plastic. The same applies to the carrier 1.

In the in the Figures 7-9 illustrated variant of the invention Rollrostes a deployable head part 7 is additionally provided. The erectable head part 7 is formed by two carriers 1 are connected to each other at the end of the rolling grate via a common rod 8 at each end. The rods 8 are pivotally connected to a further rod 9, which is arranged parallel thereto and hingedly connected to the rod 4 of the adjacent support 1. Not shown here, known per se, the head part 7 can be found in one or more positions. At the other end of the roll grate, a suitably trained upright footboard can be provided.
