be, whereby a holding support of the handle part with the floor or with the ceiling is obtained. The rotatable element of each wall element is arranged so that a single crank, which is exposed at the side of the wall elements, can be used to simultaneously move each of the individual grip parts in its extended position when the individual wall elements in a Community ä seed Are arranged level.

For this purpose there is a horizontal control rod arrangement with coupling members at the adjacent ends between two wall elements are provided in such a way that after the adjacent coupling members are in radial alignment have been brought, the control rods of each wall element can be rotated.

The foldable wall shown in Fig. 1 has for the case of

i play six wall elements 2o in two groups of three each

Wall elements. Each of the wall elements of the group is hinged so that it can be folded accordion-like with respect to the others and is mounted so that it can be rolled out of the way to one side of a fixed support part 21 'of the space to be partitioned

can. At each end of the carrier part 21 there are side supports 22 and 23.

The frame of each wall element 2o has profiles 2k and 26 at the opposite ends of the latter. The sides of the frame are generally defined by profiles 27, 28 which are substantially W-shaped in cross-section. The profiles 24, 26 are arranged in such a way that they form a recess at the upper and lower end of each wall element 20, while the profiles 27, 28 are each arranged with their web part facing outwards. Material plates 29, 31 form the front and rear sides of each wall element 2o, the middle wall element 2o of each group of three wall elements is articulated to the others on diagonally opposite edges so that the three wall elements 2o of the group can be folded out of the way like an accordion, ι

Each wall element is hung so that it can be rolled along a rail 32, which is in the illustrated fuhrungsform from an extruded section with wings 33 which can be fixed along the lower edge of the support part 21st The rail 32 has two opposite strips 34 which are facing each other

To move the support rods 63, 64 with respect to the Housing 52 to the outside are provided means which are described in more detail below.

A control rod assembly 73 is supported so that it extends between the sides 74, 76 of each wall element 2o. The control rod arrangement 73 comprises a threaded spindle 77 which is mounted between the cables 53, 5 ^ of the housing 52. When rotated in this way, a spindle nut? S is movable on the spindle 77.

BATH ORIGINAL

Line rotation of the spindle 77 has the consequence that the Nut 78 moves along this, whereby an outward 'acting force on the support rods 63, 64 on the Screw firing 83, 84 is exerted. The springs 83, 84 allow that the spindle 77 rotates a little further after the support rods 63, 64, the handle parts 44 to Have brought system to the respective room areas.

The control rod arrangement 73 has means for transmitting a rotary movement to the spindle 77. Each end of the spindle 77 carries a pivot pin 88 or 89 ₈ which are also fastened transversely by a control rod 91 or 92 arranged essentially horizontally «

At the ends of the control rod assemblies 73 coupling elements are provided for coupling the control rod assemblies of adjacent floor elements ₉ so that they can be rotated together when adjacent wall elements have been pivoted together in a common plane to form the foldable wall. The coupling members are also designed so that they immediately uncouple the adjacent ReKelstangenan assemblies 73 of adjacent Wändelamente when the wall elements have been brought into their folded position.

A transverse pin 93 is guided through a retracted end portion of the rod 92 so that it extends through an elongated slot 94 in the end 96 of an extension rod 97. A sleeve 93 is attached to the extension rod 97. The sleeve 98 lit formed with a transversely extending radial groove 99 , which is intended for cooperation with a radially extending transverse tongue lol when the latter and the groove 99 are in radial alignment. The tongue lol protrudes from the end of a sleeve Io2, which is attached to the outer end of an extension rod Io3, which is similar to the extension 97 "

The rod extensions 97 and Io3 are loaded outwardly away from their respective control rods by springs. For example, a coil spring Io4 supported against a) solid, supported by the extensions 97 »Io3 retaining ring Io6.

Therefore, every time adjacent wall elements · 2o be pivoted into a common plane, the springs Io4 to elastically absorb the longitudinal movement caused by the contact in the event of poor alignment between the tongue lol and the groove 99 is caused. By turning one or the other, a radial expansion

109840/0114

alignment can be brought about, in which case the spring Io4 brings the sleeves 98, Io2 together so that the tongue lol is firmly in engagement with the groove 99 «

vienn each of the three wall elements 2o one of the ones shown in FIG groups shown has been arranged in such a way that »it lies in a common plane, the coupling between the adjacent ends of the control rod assembly of each wall member are brought into engagement so that rotation one causes radial alignment on each coupling and eventually all of the rods rotate together.

The slight rotational movement required to establish radial alignment on each coupling becomes cumulative, with the coil springs 83, 84 of each assembly 51 serving to accommodate the additional rotational movement required for the first rack assembly ^; 73 is required, which is initially notified of the rotation. The cumulative rotational movements required to couple all three assemblies 51 can be minimized by turning the single crank described below in an opposite direction after the first coupling has been brought about.

Like in Pig. 1, one side of each group of three wall panels 2o is exposed and with an extendable one Provided crank by which the control rod assemblies are rotated from a single side edge of the group can.

Like inPig. 5, 6 and 7, a crank is provided, that of one of the groups of wall elements on a wall element since e is worn, which, at least temporarily, is not adjacent to another wall element side is located. The crank is frictional to turn the Control rod arrangement of all wall elements "together over the radially aligned couplings coupled between them

The exposed side 111 (Fig. 6) of the wall element 2o is formed by an elongated extrusion,

^r which forms one of the profiles 28. The extrusion has

ι a vertically extending slot 113, which for An articulated crank 114 is used when it is fully extended. The crank 114 is attached to the end of the control rod 92, which is mounted in a bushing part 116 which is formed at the upper end of the slot 113. The crank 114 has three links 117, 118 and 119, which are connected to one another by pivot pins 121. That

809840/0114

Link 119 forms the handle of the crank 114. A lock with a spring-loaded cup serves to form a safety device at each joint of the crank 114. Purely for this purpose, two notches 122, 123 are provided on each articulated connection, which are arranged at an angle of 90 ° to one another are. A spring-loaded ball 124 is slidable in a coaxial bore in each link 117, 118, 119, |

When the ball 124 is in alignment with the notch 122, there is an inevitable spring lock. The crank 114 can therefore be stretched and placed in a slot 117 in which it is invisible and with the exposed Side 111 of the wall element 2o is essentially flush. When the control rod 92 can be rotated, the crank Il4 can be pivoted into the crank shape.

The mode of operation of the device described above

is as follows! I.

Assume, as shown in Fig. 1, that a group of three wall elements 2o in a folded state! is located, as indicated by the three nearest Wanc & emente ' shown in Pig, 1, and that these three wall panels are to be arranged to form a viand, as by the three wall panels shown in the background for what purpose the

901840/0114

Wall elements are rotated until they are in a common plane »

The unit consisting of three elements is then brought into the correct lateral arrangement relative to the opening, which through the carrier part 21 and the side supports 22 and 23

| is bordered. The crank 114 is out of its position within of the groove 113, and arranged in the manner shown in Fig. 5 for cranking the rod 92. When the rod 92 is rotated, the spindle nut 78 is rotated by the spindle 77 along this in the in Fig. 3 with dot-dash lines drawn position. This movement of the nut 78 serves to move the support rods 63, 64 so that the Handle parts 44 stand outward from the wall element. By the outward movement of the handle parts 44 becomes the wall element between the underside of the strips 34 of the rail 32 at the top

"End of the mantle and the floor of the room at the bottom Wedged the end of the wall element.

During the alignment movement of the three wall elements of the unit in a single vertical plane, the tongues lol may have been brought into alignment with the grooves 99. If this is not the case, the springs Io4 take up the longitudinal movement of the rods 91, 92 elastically. During an initial

909340/0114

partly the rotation of the threaded spindle 77 (which rotation of the spindle is communicated by the crank 114), however, the rod 91 is inevitably rotated so that the groove 99 and the tongue lol are brought into radial alignment, so that by a further rotation of the crank 114 not only the support rods 63 »64 of the first wall element extended
