Definitions

• the invention relates to a portable reading stand.
• the prior art embraces portable reading stands of the type comprising a frame equipped inferiorly with three support feet, foldable about the frame itself, and means which together provide a rest plane for newspapers, musical scores and the like, which means are foldable in such a way as to give rise to the least overall mass possible, and which are generally constituted by flat inter-hinged arm systems.
• the drawback exhibited by reading stands of known type is that when folded into their smallest mass they are unstable and tend to open out, thus becoming impractical. This drawback of instability occurs also when the stand is open, and even the opening manoeuvre itself is somewhat difficult.
• the principal aim of the present invention is to obviate the above-mentioned drawbacks by providing a portable reading stand which is practical to use and easily transportable in a compact shape.
• An advantage of the invention is represented by the simplicity of the manoeuvres needed for folding and unfolding it as well as the speed with which these operations can be done.
• figure 1 shows the reading stand in a closed transport position, in a partially sectioned longitudinal view
• figure 2 shows the stand in open position in frontal view
• FIG. 6 shows, in frontal view, the stand in an open position according to a further embodiment.
• 1 denotes a portable reading stand comprising a frame 40 inferiorly equipped with stand organs 41.
• the frame 40 comprises a tubular element 2, a tube 4 telescopically coupled internally to the tubular element 2 and a base element 5 housed internally to the tube 4 and free to slide vertically.
• the stand organs 41 comprise three feet 3 hinged to the inferior end of the tubular element 2.
• the base element 5 bears a hollow body 7, rotatably coupled by means of a pivot 6 and internally provided with foldable rest means 8 which, once unfolded, define an inclined rest plane for newspapers, musical scores and the like.
• the rest plane is materially defined in the first embodiment, indicated in figures from 2 to 5, by a flexible sheet 9 tensed between two ends and in the second embodiment, in figures 6, by a flat hinged system of rods 10.
• the three feet 3 are symmetrically arranged with respect to the tubular element 2 and are constrained to the said element 2 by means of cylindrical hinges of the fork type with rotation axis normal to the tubular element 2 itself.
• the rotation of a foot 3 is stopped in two predetermined positions, one a transport position and the other a support position. In the transport position, indicated in figure 1, the feet 3 are arranged contiguously to the external surface of the tubular element 2, while in the support position, indicated in figure 2, they are arranged in such a way as to support the stand 1 by forming a tripod.
• the blocking of the feet 3 in the two above- mentioned positions is effected by a stop 11 arranged inferiorly to the tubular element 2 and constrained to it by means of a sliding couple with interposition of a spring 12.
• the stop 11 is equipped with a contrast edge 13 able to engage with two specially shaped cavities 14 present in each rod 3.
• the disengagement of the edge 13 of the cavity 14 is obtained by sliding the stop 11 upwards by compressing the spring 12 acting on the end 15 triangular in section, of the stop 11, which projects inferiorly from the tubular element 2.
• the stability of the above-mentioned support position is ensured by the surfaces 16 and 17, respectively belonging to the feet 3 and the stop 11, which come into reciprocal contact preventing further rotation of the feet 3.
• the base element 5 is constituted by a lower part
• the 22 comprises friction elements, constituted in the example by rotation surfaces 23, which ensure a grip between the parts, in a determined position, by friction or by jointing.
• the sheet 9 can be wound on a cylindrical support 27 predisposed internally to the hollow body 7 and hinged to it.
• a torsion spring acts on the support 27 forcing it to rotate in the winding direction of the sheet 9.
• the sheet 9 is connected on one edge to the support 27 and on the opposite edge to a rod 28 provided with a recess 29 predisposed to couple with special projections 30 present on the base element 5, having the function of preventing the rewinding of the sheet 9 by return effect of the spring, stopping the rod 28 in predetermined positions.
• the rest means 8 are constituted by an inter- hinged arm 10 system, connected to a rod 32 and a slider 31.
• the rod 32 is rotatably coupled to a slide 24' which is identical to the slide 24, slidable with respect to the base element 5, as is the slider 31.
• the arms 10 are conformed in such a way as to be foldable against the rod 32 so as to enter the tube 4.
• the tube 4 and the base element 5 are contained internally to the tubular element 2, against which external walls the feet 3 are folded flush.
• the use configuration is reached from the portable configuration by performing the following operations: bringing down the feet 3 into the support position, which is done simply by pressing the end 15 of the stop 11 to the ground (or by manually rotating any one of the feet 3 which automatically unblocks the other two feet, permitting relative rotation); unscrewing the collars 18 and 19 as much as is necessary to loosen the grip and permit the sliding of the tube 4 and the base element 5; rotating by 90 degrees the hollow body 7 or the rod 32 and unfolding the rest means 8.
