For this purpose the swing out arm comprises a remote bearing point,, via which tint leaf is held and supported.

The closed position of the leaf and the opets position of the leaf are also to-tended indtreeily. lust is; this ease based on the eorrespottdiug positions and pivot positions of (he arms o f the carriage, which is claintcd w-ithoot leaves.

Its this ease, too, is should he mentioned that site shear guides and a pitnalny of shear assemblies on she upper face of the leaf do not require any specific explanation since they are of -conventional construction and eats be found in the prior ad. The emphasis here lies with the claimed ramage and the design of site carriage.

The swing out ans; cats be formed in such a way shat it enables the control artn to he covernd completely this is described with reference to a pivot plane.

The function of the feature is based on the locked position of the control arm, i.e. a position io which the end <d the control arm s.s locked in at one end of the golds of fne control portion,

The difference of the hidircctiostai doable stud is clearly acknowledged. Front above It is: released (from the control block) and iront below or "downwards" If is guided fin the control portions. In the assembly region of the double stud, which is mounted on the end region preferably in rite fosro oi'tbc curved portion of the control guide, a peripheral collar is produced which projects beyond the dinxensums of the control sttid in the tadiai direction. This cedar will he described us greater detail for other securing, purposes. A releasably locked position is aelheved by the downwardly projecting protrusion in ass angled end regi»« of the guide. This position cuss be secured, for which purpose a spring element ss used which exerts pressure or force in a horizontal direction. This force is exerted over a lateral plate protrusion onto the curved portion as the front earl region thereof, The force sets, at least its pan, in the direction of the angled path portion.

This overlap may be present itt the locked position and is also present whilst the control arm is removed» io a controlled manner, from the controi block out of the locked position via the upwardly projecting pin and is received, in its holding effect, by the control block and its path-like entry.

The transition of the locked position on the controi porított towards the controi block on the w indow or door frame is secured by the overlapping portion. A telesse or lain ng out tspw&amp;roly is tints effectively prevented The upwardly arranged spring piece which sa displaceable in the transverse direction Is provided at another polar of the housing; area itt an end portion.

Accotdingiy, a very long log is intended, which is slender in cross-section compared to its length. The control block itself is to be mounted on the window or door frame in the running rail on the side pointing into the room and stands in the longitudinal direction in the path of travel of the carriage, or rather the housing atea thereof. It is arranged above the guidance path for the castors and forms the and of the path of Pavel of the carriage with the position O of the swing-out arm. ti guides the control arm out of the retracted posdion via the upwardly projecting protrusion, such that the carriage can move back in the opposite direction on the castors. the protrusion is reliably received and remains in the oath-like entry in the controi block, and the sulng-out arm, controlled by She control arm, is moved back into the position S. The leaf approaches the win-how or door frame and the closed position. Owing to the design of fite bulky swing-out arm, the bearing capability cam he ensured, with simultaneous covering of the visible side, when the slit receives part, tt sstbsfantiai portion per sc of the control arm, and the slit does not penetrate completely through the swing-ostt arm in a transverse direction, but extends in the direction of depth ooh t<* a limited extent.

The adaptation of these geotnetries makes it possible to have a slender, compact design, simultaneously to enable controls, and So appear virtually cmnpfeteh compact in the closed position, as oars be seen very clearly in Fig, os.

The control, which has already been jnenlfened, fakes place v?a a double protrusion 39 which has su upwardly projecting protrusion 3¾ and a downwardly ptojeoting protrusion 39b.

The double protrusion, which can. be sect? tfom. ad views m Fig. 2, Fig 6b and the enlarged detail shews of Fig. 11 and 12, has two different ftmetiems or roles above andbehtw with a substantially identical design.
