The swinging movement of these is limited by supports arranged on the fall front and/or on the rear wall which do not protrude very much and which can be adjusted from the interior of the cabinet by turning a single component.

DESCRIPTION OF THE PRIOR ART In this sort of cabinet, the fall front may be swung in an arc, while the straight rods and tubes slide telescopically one in the other. A certain amount of play is therefore necessary; this is obtained in usual construction of such a cabinet by making the rods and tubes for hanging articles to be stored not only swingable about their fixtures but also able to execute an up and over movement.

The adjustability of the supports for the hanging rods and tubes is provided for the reason that the material of the cabinet, usually wood, changes in shape on loading, and this therefore often makes necessary subsequent adjustment of the supports for the hanging devices. Additionally, on account of the small lever arm between the pivot point of the hanging rods and tubes and the actual support, a substantial pressure is exercised on this support by the weight of the drawings or the like.

In one known construction adjustable shackles are provided on the inner wall of the cabinet as adjustable supports. In another construction, in which the hanging devices can make both a swinging movement about their fixtures and an up and over movement, grub screws are provided accessible from outside at the support positions of the hanging rods or tubes, which can be fixed in various positions by means of locking screws. It is also known to make both the pivotal fixture for the hanging device or parts and the supports limiting their movement as a single component. In this construction, for adjusting the support point of the swingable hanging rods or tubes, a screw threaded rack is provided in each case which is accessible from the interior of the cabinet. However these screw supports which are adjustable and which are arranged inside the cabinet are difficult to reach. In the cabinet described in the introduction above, the adjustable supports have set screws against the end of which an arm rigidly connected with each hanging rod or tube can lie.

It is an object of the present invention to provide, in a cabinet of the type noted above, a simpler means which is easier to install for the adjustment of the supports. For this no construction would be useable in which the adjustable support extended into the interior of the cabinet, since space for storing drawings would be lost and damage to the drawings by that support would be possible. Additionally, the support should be adjustable from the interior of the cabinet since because of crowding together adjacent cabinets in use, it is very difficult, or in some cases totally impossible, to carry out any adjustment from outside, especially to the rear wall of the cabinet, if the loaded cabinet is located against a wall.

GENERAL DESCRIPTION OF THE INVENTION According to the invention, this problem is solved in that of the adjustable supports at least one includes a turnable disc formed with several support positions around its periphery, the support positions being arranged at various distances from the turning axis of the disc.

Since the amount of support adjustment needed is often comparatively small it may be sufficient to have a comparatively small number of cutouts each of different depth around the periphery of such a turnable disc.

If a greater amount of fine adjustment is desired, this invention contemplates that the outer edge of the turnable disc be of generally spiral shape and depressions of the same size or of various depths be provided around the periphery, each depression constituting a support position.

The turnable disc is provided with a central fixing means, for example a threaded bolt or the like, which simultaneously serves as the axis for rotation. Additionally, according to one embodiment of the invention there can be provided on the interior wall of the cabinet and on the side of the turnable disc towards that wall, parts engaging with one another and securing the turnable support disc against any undesired turning. The mutually engaging parts can, according to one embodiment of the invention be engaging teeth.

If during use the weight of the sheet element put on the hanging device should change, it is only necessary to loosen the bolt of the turning disc and to turn the disc through one or more depressions to a suitable ex-. tent until the desired position of the hanging rods or tubes is again reached. Thereby it is possible in simple fashion to fix the new storage position for the hanging device, which must be so arranged that on the closing movement of the fall front, both tube and rod come together again smoothly and engage in one another without difficulty.

According to a further advantageous embodiment of the invention it is contemplated to arrange in place of one turnable disc two or even more turnable discs behind one another, wherein the support positions on each can be displaced from one another, in order to provide an improved fine adjustment of the vertical position of the hanging device.

Handling the supports is very simple and they are easily accessible from the interior of the cabinet. The construction chosen requires little space since a comparatively flat disc can be used which in practice does not diminish space inside the cabinet for the receipt of drawings and the like. Furthermore the construction chosen is simple and economical to manufacture since the turnable discs may be constructed as stamped pieces and require no further machining operation.

Special openings in the walls of the cabinet for the turnable discs are not necessary.

DESCRIPTION OF THE DRAWINGS By way of example only, two embodiments of the invention are illustrated in the accompanying drawings in which:

FIG. 1 shows a front view of a first embodiment,

FIG. 2 shows a front view of an alternative embodiment, and

FIG. 3 shows schematically a section through a cabinet of known construction for the hanging storage of sheet articles,

FIG. 4 shows a partial longitudinal cross-section through the hanging storage cabinet, illustrating the type of mounting of the hanging means and the support for the hanging up means.

According to FIG. 3 a cabinet'4 for the hanging and storage of sheet articles has a fall front 5 which can be fixed in the closed position and in the open position (shown in dotted lines) by a locking device 6. The cabinet has a hinged lid 7 which may be lifted up on a hinge 8 at the back of the cabinet. On the fall from 5 and on the rear wall of cabinet 4 there are affixed hanging rods and tubes denoted 9 and 10 respectively; these are fixed by

pivotal means

11 and 12 onto the fall front 5 and onto the rear wall.

In the section of FIG. 3 only one hanging device 9 and 10 is shown; each device comprises a rod with a pointed end 9 and a tube 10. According to the invention, the support at least for the tube 10, fixed to the rear wall of cabinet 4, consists of a circular disc 13 of hard material (see FIG. 1), particularly metal, steel or the like which has about its periphery a number of cutouts 14, 14a, 14b, which, seen from the periphery of disc 13, each have a different depth. The disc 13 is fixed to the inner wall of the cabinet by means of a fixture numbered 15 which for example can consist of a bush (not shown) with a threaded bolt, wherein the bush outwardly bears the tumable disc. In an alternative construction, the disc 13 may be supported by a ball bearing.

' FIG. 2 shows a modified construction of the tumable disc, here denoted 16, in which the individual support positions, denoted 17, 17a are arranged on a spiral denoted 18, so that the distance from the axis of rotation of the disc continuously changes. The individual cutouts in the form of support positions 17, 17a may have the same depth or may have suitably varying depth, in order to increase the possibility of variation in the position of the hanging rods 9 or tubes 10.

In order to alter the support position of the hanging device 9, 10 it is only necessary to loosen any locking of disc 13 or 16 and to turn the disc one or more cutouts further until the desired height adjustment of the support, and thereby the relative position of hanging means 9 and 10 to one another, is determined.

From the illustration of FIG. 4 can be seen how the hanging means are mounted within a cabinet and how the support is arranged on the inner wall of the cabinet. In the illustrated embodiment there is fixed in the wall of the cabinet a mounting means 19 with an inner flange 19a for the hanging means, said mounting means carrying a horizontal pin 20 on which the hanging means 10 is pivotally supported. The opening in the holding means 19 is adapted to be closed a screw cap 21 or the like.

The flange 19a is provided at 22 with a threaded bore into which bolt 15 is screwed to releasably and fixedly adjustably carry the tumable disc 13 or 16.

It is possible to provide, on the rear side of the turnable disc and on the inner wall of the cabinet, additional locking means by which any undesired turning of the disc is hindered. This locking means can, for example,

com rise mutually engaging teeth on the rear side of the urnable (118C and on the inner wall of the cabinet.

The teeth on the inner wall of the cabinet may be formed on a special inner locking plate.
