Description

The present invention starts from a device for holding objects in

  sheet form, according to DE C 24 33 528, in which the sheet is held in a position suitable for reading, applied by a spring pressure, partly against

  a curved surface whose curvature extends horizontally

  along a vertical axis, the spring being constituted by a flexible blade extending over the entire lateral length of the sheet, which presses the sheet in working position against the curvature, and which can be brought backwards by means of a lever attached to him, to allow the introduction of the

information sheet.

  The object of the invention is to constitute this known holding device in such a way that its handling, from the point of view of bringing it back and bringing it

  in the working position of the flexible blade, for the introduction

  duction and output of the information carrier either

  clearly facilitated, while taking into account the

  simplification of this holding device.

  For this purpose, the subject of the invention is a sheet-shaped object holding device of the type mentioned

  above, which is characterized in that the flexible blade

  ble is provided, at least at one end, with a gripping and levering member on the blade, and which protrudes laterally on the body having the curvature This gripping and handling part can be provided for plug it onto the flexible blade, or be connected to it in one

piece.

  With the sheet-holding device according to the invention, the important advantage is obtained that the movements brought back and brought into the working position of the flexible blade can be performed in a very simple manner, by a pressure or a traction on the actuating piece projecting laterally on the blade body having the curvature Since the "tilting" of the flexible blade in its support bearings takes place by simple spring effect of the blade itself, it is sufficient a light touch of the workpiece with the finger to bring the blade into each of the two

possible positions.

  The invention provides various constructional features relating to preferred embodiments of the blade actuating member and

support modes.

  The following description refers to an example

  non-limiting embodiment of the object of the invention, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of the device according to the invention; Figure 2 is a side elevational view, on an enlarged scale, of an outer end of the flexible blade with the operating part plugged on it; Figure 3 is a perspective representation of another embodiment of the holding device according to the invention; FIG. 4 is a side elevational view of a flexible blade for the holding device of FIG. 3, and FIG. 5 is a perspective view of another alternative embodiment of the holding device.

according to the invention.

  As shown in FIGS. 1 and 2, an exemplary embodiment of the sheet-shaped object holding device according to the invention consists of a

  body 1 made of synthetic material or synthetic glass

  tick, which has, on one side, a concave curvature 2,

  and which can be fixed, for example by means of an articu-

  ball joint 3, at a table, a typewriter or

data processing apparatus.

  At each end, the body 1 presents respectively

  A recess 4 and 5 of angular shape oriented inwards towards the curvature is inserted into these recesses. A flexible blade 6 is inserted therein, preferably made of transparent material, and projecting from each side.

  on the thickness of the body 1 For this purpose, this flexible blade

  6 has, at one of its ends, a recess 7, and in the region of the other end, a recess 8, whose inner edges are applied in the recesses

  angular shape 4 and 5 respectively.

  On one of its ends, the flexible blade 6 is provided with a gripping and actuating piece 8, plugged on it, which, for this purpose, is recessed U-shaped on one side with, in each of the branches of this U, a groove 10 and 11, in which is engaged the edge of the

  blade 8 in the zone of its outer end.

  With a simple pressure or a slight touch of the finger of this operating part 9, the band 6, acting as a spring, passes with a click, from the working position shown in full lines in its open position 6 ', shown in dashed line, in which case the operating part, after displacement in the direction of the double arrow 12, is placed in the position 9 'shown

dotted.

  In this open position, it is possible to insert a sheet by sliding between the curvature 2 and the flexible blade 6 'which is in an opposite curvature, after which, by simple contact with the operating part 9' in the opposite direction of the double-arrow 12, the flexible blade returns applied to pressure on the curvature

2 by immobilizing the sheet.

  FIG. 3 shows another possibility of mounting the flexible blade on the body 1 having the curvature 2. The body 1 then has at each end an appendage, 13 and 14 respectively, each provided with a recess 15 and 16 '. extending inward. As shown in Figure 4, the flexible blade 6 has, for this purpose, at one of its ends, a protruding tongue 17, and in the region of its other end, a recess 18 in which protrudes another tongue 19 The maneuvering room 20 is in

  this case made in one piece with the flexible blade.

  Another operating part 20 ', indicated in phantom, may be provided symmetrically at the other end of the blade 6 The two tongues 17 and 19 are engaged in the appendages 13 and 14 of the body 1, so that the flexible tape can take the same positions as in

Figure 1.

  FIG. 5 shows another possible embodiment of the holding device of the invention. In this example, only one end of the body 1 having the curvature is provided with a small appendage 21 having a recess 22 at the other end. of the body, the flexible blade 23 is connected to the body 1 by a hinge-shaped film 24, and the operating part 25 is connected in one piece to the flexible blade 23 The flexible blade 23 has, to the other end, a tongue 26 which is inserted into the recess 22 of the appendix 21 In this case, the flexible blade 23 can take exactly the same positions as in FIGS. 1 and 3, in particular

  the position 23 'indicated in dotted line.

  The band 23 may have a recess 27 extending over most of its length, and serving as a visibility slot, through which is possible an unhindered reading of the sheet or

  information carrier placed below the blade.

  The flexible blade could, instead of the tongue on its outer end, be connected to the body 1 with

a second film hinge.
