EACH OF THESE UPRIGHTS INCLUDES A METAL TUBE 3 AND TWO SCREWS WITH 4 SCREWS RESPECTIVELY IN REVERSE DIRECTION ON THE TWO ENDS OF THIS TUBE, EACH CYLINDER HAVING A THREADED ROD HAVING ONLY THE OUTER DIAMETER IS LIGHTLY LOWER IN THE DIAMETER OF THE TUBE, A ROD INTRODUCED INTO THE TUBE ON A RELATIVELY LONG LENGTH, A NUT SCREWED ON THIS ROD AND TAKING AXIAL SUPPORT AGAINST THE CORRESPONDING TIP OF THE TUBE, AND A PRESSURE DISTRIBUTION PLATE REPORTED ON THE EXTREMITY, THREADED, OUTSIDE THE TUBE.

Description

Improvements to the shelves.

  The invention relates to interior shelves

  Laughter comprising superimposed horizontal shelves supported by vertical uprights forming legs. It aims, above all, to make these shelves particularly easy to manufacture and assemble, whatever the height under ceiling of the reception room

  and the state of flatness of the ground or floor.

  To this end, the shelves according to the invention are essentially characterized in that each of their uprights comprises a metal tube and two screw jacks mounted respectively in opposite directions on the two ends of this tube, each jack itself comprising a rod threaded whose outside diameter is only slightly less than the inside diameter of the tube, rod

  introduced into the tube over a relatively long

  gueur, a nut screwed on this rod and bearing axially against the corresponding end edge

  of the tube, and a pressure distribution base

  carried on the end of the external threaded rod

to the tube.

  In preferred embodiments, it has been shown

  in addition to one and / or the other of the following provisions: - the rod, the nut and the base of each jack are made of a hard plastic material, - the hard plastic material is an acetal resin,

  - the output end of the rod of each cylinder is avoided

  axially delivered by a threaded bore fitted by a threaded centering pin,

  - the outside diameter of each threaded rod is com-

  taken between 2.5 and 4 cm and its axial length is com-

  taken between 15 and 30 cm, - the number of the uprights of the shelf is equal to two, - each upright is perforated with a series of pairs of diametrically opposite holes, suitable for receiving bars for supporting the shelves, - the portions of each tablet, which rest on a bar are two sides of this tablet arranged on either side of a deep notch hollowed out in a small side of said tablet, notch whose edges

  are suitable for overlapping each tube jointly.

  The invention comprises, apart from these arrangements

  main provisions, certain other provisions which are preferably used at the same time and which will be

  more explicitly question below.

  In the following, a preferred embodiment of the invention will be described with reference to

  drawing appended hereto in a way of course not limited to

tive.

  Figures 1 and 2 of this drawing show res-

  pectively in elevation and in lateral view along II-II,

  Figure 1, a shelf established according to the invention.

  Figure 3 is an enlarged elevation and cutaway portions of the base in the amount of

this shelf.

  FIG. 4 is a plan view, also on a larger scale and parts broken away, of the portion,

  of said shelf, designated by arrow IV on the figure

gure 1.

  The shelf includes two vertical uprights 1

  forming legs and horizontal shelves 2.

  Each upright has a metal tube 3 and

  two screw jacks 4 mounted in opposite directions, respectively

  the two ends of the tube 3.

Each cylinder 4 itself comprises:

  - a threaded rod 5 whose outer diameter, relatively

  fat and generally between 2.5 and 4

  cm, preferably around 3 cm, is only small.

  significantly smaller than the inside diameter of the tube 3 and

  whose length is relatively large, being generally

  generally between 15 and 30 cm, preferably of the order of 20 cm, a nut 6 cooperating with the rod 5, - and a base 7 attached to one end of this rod.

  The end of the rod arranged on the side of the em-

  base 7 is preferably pierced axially by a bore

  threaded age, which is trimmed by a metal pin

  threaded 8, spindle which crosses axially uivtrou cen-

tral hollowed out in base 7.

  The rod 5, the nut 6 and the base 7 are pre-

  ference made of a hard plastic suscep-

  tible to be mass dyed, for example white or black. Such a material is advantageously a

  acetal resin such as that marketed under the ap-

DELRIN blow job.

  Each tube 3 is pierced by a series of pairs of diametrically opposite holes 9 suitable for receiving

  rigid bars 10 for carrying tablets.

  The short sides of these shelves are hollowed out by deep grooves 11 whose bottom has the shape of a semicircle and whose parallel sides are

  suitable for overlapping the tubes 3.

  To set up an amount 1 between the plan-

  expensive 12 and the ceiling 13 of a local spread one of

  the other of a height H, we proceed as follows.

  We start by cutting the tube 3 to a long

  about 20 cm lower height H. The two cylinders are inserted into the two ends of this tube, with their relatively small nuts

close to their bases.

  If the pins 8 are provided, two small positioning holes are drilled respectively in the floor and in the ceiling to receive these pins and the latter are introduced into these holes after having adjusted by screwing their lengths which protrude in

outside the bases 7.

  Then the two nuts 6 are screwed so as to apply them axially against the edges facing the tube 3, which at the same time applies the two bases 7

  respectively against the floor 12 and against the floor

background 13.

  This simple screwing ensures extreme fixation

  solid amount 1 between the floor and the floor

background.

  In particular the vertical guide of the tube 3 is

  ensured by the fact that the portions of the rods 8 intro-

  almost joined in its two ends are

  relatively long, and usually both

lower & 10 cm.

  To place a tablet 2 on two of these

  tants previously put in place, we put on two bars

  rettes 10 in two pairs of corresponding holes 9 provided respectively in these two uprights at the same level, then the shelf is tilted so that one of its short sides is at the bottom and this small side is placed on the one of the two bars, overlapping the corresponding tube 3 by the edges of the notch 11

hollowed out in said small side.

  Then lower the other side of the

  tablet and when it reaches its horizontal position

  tale, the edges of the notch 11 hollowed out in this other side come to overlap the second upright, and the two sections of shelves delimiting this notch

  rest on the second bar: indeed, well understood

  du, the distance separating the bottoms of the two notches 11 of the tablet was chosen equal to the distance which

  separates the two faces opposite the uprights.

  Following which, and whatever the embodiment adopted, we finally have a shelf

  whose constitution and assembly are sufficient

ment of the above.

  This shelf has many advantages over those previously known: in particular, it is extremely easy to adapt it to rooms with different ceiling heights and

  inclined or irregular floors; moreover, she is robus-

  te, aesthetic, made up of a very small number of elements

  and its assembly does not require any tool from the

  O10 type of screwdrivers or tightening wrenches.

  As it goes without saying, and as it results from

  their already from the above, the invention is not limited

  in no way to those of its modes of application and implementation

  which have been more specifically contemplated; she in

  embraces, on the contrary, all variants, notably

  ment: - those where the base 7 of the upper cylinder would only bear lightly on a false ceiling or the like, the axial pressure necessary for fixing the upright then being transmitted higher to a real ceiling by

  through the central rod 8, provided sufficient

long enough for this purpose,

  - those where at least some of the shelves 2 extend

  would asymmetrically compared to the uprights 1, as is the case for the enlarged one, represented at the bottom of FIG. 2, which constitutes for example a work plan, - those where at least some of the shelves would be constitutive elements of more complex assemblies such as boxes, lockers, reception frames for hanging files, etc.
