Description

The present invention relates to a modular assembly for the realization

  a decorative structure for flowering, and structures made with such a set.

  Structures of this type are already known in the prior art, for example that of document EP 0291 384 which consists of a vertical mast axially passing through a stack of several tanks with water reserves of different sizes.

  Each resin tub is shaped according to a succession of expensive and complex cone trunks. In addition, such a structure is only suitable for small compositions, for example suspensions.

  The invention aims to provide a modular structure that can be made of metal sheet to reduce manufacturing costs, increase resistance and service life, can be installed and easily modified, and which is resistant and inviolable and of sufficient size. to constitute street furniture.

  These objectives are achieved by the invention which consists of an assembly for the production of a decorative structure for flowering of the type comprising a plurality of tubs for planting flowers or plants, a central mast on which the tubs hang. staggered, characterized in that the assembly is composed of a set of basic elements allowing multiple combinations of structure, namely: - a central mast comprising a plurality of positioning holes, - a set of connecting pieces , each able to be crossed by the mast and to be positioned on one of the positioning holes, - a plurality of tanks of the same flared shape, each locked in vertical direction between two successive connecting pieces, and also blocked in rotation , each tray being extended by a sleeve-shaped part which can surround the mast and serving as a spacer between two successive trays, and each tray being locked on a connecting piece by a plurality of pins or studs, - a lower base keeping the mast in a vertical position, - a locking means for blocking the structure after assembly of the elements.

  The invention will be better understood with the aid of the description below of a non-limiting embodiment of the invention made with reference to the following appended figures: FIG. 1 shows a first example of implementation of the modular structure according to the invention called "ball and tree configuration", - Figure 2 shows another example of implementation called "pyramid configuration on foot", - Figure 3 shows an overview of a tank, - Figures 4a, 4b, 4c, show a connecting piece, - Figures 5a, 5b, show a base, - Figure 6a and 6b show a detail of the assembly, - Figure (7) shows as a example a flowery composition in a spiral.

  All the constituent elements of the modular structure and detailed below, are composed of: - a plurality of tanks (1) with preferential semi-hexagonal section of the same flared shape and preferably of different sizes, - a central mast (2) , possibly extendable, - a set of connecting pieces (3) with a preferential hexagonal section, a lower base (4) for example made up of a gusset plate 15 (5) or a base (6), and now the mast (2) in vertical position, - a blocking means (7) making it possible to block the structure after assembly of the various elements. ferry

  A tank, see Figure 3, is made of welded galvanized sheet metal and has a closed bottom (8) semi-hexagonal, horizontal, a vertical wall (9) according to its largest dimension, and three side walls (10, 11, 12) flared so that the upper opening (13) of the tank forms a half-hexagon larger than that of the bottom (8).

  A plurality of ribs (14) or any other equivalent means is provided at the bottom of the tank to support a double bottom (15) which may or may not be removable (grid, perforated sheet metal, or the like) partially represented and which supports the soil for cultivation. , in order to provide a space between the bottom (8) and the double bottom (15) serving as a water reserve.

  An essential functional element of the tank is the vertical sleeve and with a semi-hexagonal preferred section (16) provided in the middle of the vertical wall (9), and of height (H) greater than that (h) of said wall (9). The sleeve has a spacer function, the height (H) of which defines the spacing between two successive trays and is terminated at the top by a horizontal semi-hexagonal plate (17) pierced with a semicircular cutout (18 ) of diameter allowing the passage of the central mast (visible in the other figures and for the passage thereof), and a plurality of assembly holes (19), for example three. One or more folds (21) may be provided for the passage of one or more pipes (41) for the automatic irrigation water supply.

  Furthermore, in order to optimize manufacturing while allowing a very large number of structural combinations and final shapes in terms of floral composition, provision is made to manufacture a limited number of basic tubs, for example three or five of different lengths (per example L = 650 mm, 900 mm, 1200 mm, 1000 mm, 700mm) with the same taper for the same flare, with the same wall height (h), and with the same sleeve height (H).

  A tank preferably comprises an overflow system (27), for example a simple tube welded in a vertical position crossing the bottom of the tank (8). The pipe (27) protrudes in the volume for the reserve of water by a height less than that of the ribs (14) and also projects below the bottom (8) so as to serve as a positioning means as will be seen more far.

  The container preferably also includes a set of feet (39) or studs so as to be able to stand up, individually independently, for example for growing plants in the greenhouse directly in said container before its installation on the structure.

  Mast and assembly parts The central mast (2) is a tubular cylindrical part possibly extendable by at least one extension (21) or another mast by a conventional system, for example with sleeve and screws (31).

  The mast (2) has a plurality of horizontal positioning holes (30) 25 passing through it diametrically, and regularly spaced by a distance corresponding to the height (H) and to the spacing between two successive tanks.

  The mast is for example kept vertical by a plate (5) with gussets for fixing to the ground (FIG. 1) or by a base (6) (FIG. 2) depending on the floral configuration chosen.

  The plate is anchored in the ground on a concrete cube according to a technique known in street furniture.

  The mast may also include at the upper end a removable hooking device (22) to allow the movement of the structure by a lifting device.

  A connecting piece (3), see figures (4a, 4b, 4c), is formed by two hexagonal plates (23, 24) parallel and connected by a cylindrical tubular section (25), the internal hole (26) opening at the top and at the bottom forms a passage for the mast (2).

  One of the plates (23) is smaller than the other and has six holes (28) spaced regularly (see FIG. 4c) in a circle and on the perpendicular bisectors of the sides of the hexagon to receive the fixing pins or closing screws. for the last stage of the composition.

  The largest plate (24) has six holes (40) in the axis of the holes (28) and also six holes (29) distributed regularly in a circle on the perpendicular bisectors of the hexagon, their diameter is provided to receive the pipe overflow of a tank and / or the water inlet hose.

  The tubular section (25) of the connecting piece comprises a transverse positioning bore (34) threaded at the end (34b) for the installation of a screw (not shown) whose head is embedded in a shoulder (34a) , said hole passing through the mast at the chosen positioning hole (30).

  A base (6) fixable to the ground as shown in figures (5a and 5b) comprises six feet (31), angles (32) in a star shape so as to form a hexagonal structure supporting a lower sleeve (33) capable of receiving Matt.

  The base is designed so that it can be placed there on a piece (24a) identical to the large painting of a connecting piece, directly a container (1) or a basin made up of two half-containers (1) assembled between them, and no part of the base protruding from bins for safety, while allowing the passage of the forks of a forklift.

  A threaded locking means (7), intended to be screwed into the connecting piece (3a) terminating the structure, has the function of locking the structural elements 25 between them. After blocking, all the tanks are immobilized between the connecting pieces, the fixing studs of which are themselves inaccessible and therefore cannot be dismantled.

  Preferably the locking means consists of three screws screwed into the holes of the last connecting part which are threaded.

  Assembly It is always carried out by first setting up the lowest parts and progressing upwards.

  As an example, the so-called "tree" structure of FIG. 1 can be produced.

  Three connecting pieces are positioned on a lowest shaft (35) arranged 35 with the largest plate facing down, all of the following having the large plate facing up.

  We put on each piece of the connection (n) either a tray, or two neighboring trays by applying them one against the other, and holding them by the lights (20), and by snapping the overflow (s) ( 27) in one or two holes (29) of the large plate on which the said container or containers rests.

  In the figures (6a, 6b), each tray is held by a small tray of the connecting piece located above it, the small tray being inserted in the sleeve and under the plate (17) of the sleeve, then locked by pins or studs (42) passing through the holes (28 and / or 40) of the plates and (19) of the plate (17) and made inaccessible because covered by the next tank.

  We thus successively mount all the necessary stages and we end with a connecting piece (38), with its large plate above, in which we can screw the locking screws (7), which replace the studs at the level of the latter. connecting piece (38).

  Any other assembly is possible to obtain any type of floral decoration, for example: - in a ball and in a tree (figure 1) with a larger basin on the floor in the middle, - in a pyramid on a base (figure 2) with basins or tray of decreasing sizes, - in a spiral, if two successive trays are angularly shifted when the overflow is clicked on (see Figure 7).

  - in a half pyramid, which can be placed against a wall, using only one tray per floor, - by choosing a different number of floors, - in a column, with identical trays (case not shown).

  To meet the safety standards governing the construction of street furniture, at least the following arrangements are made: - pins or fixing studs which cannot be removed, making the structure tamper-proof, teardrop finish on the upper edge of the tanks, - non-overhanging base .

  A structure according to the invention has many qualities and advantages in particular: - possibility of realizing urban furniture and not only 35 flower boxes. For example, structures can be made up to 4.40 m high and 1.20 m wide.

  - Easy assembly, assembly and modification, - multiplicity of combinations, - possibility of storing trays in the greenhouse for direct cultivation of the plans in the trays, - possibility of painting at least one element, for example the mast, - further development and improvements possible for example: * addition of an automatic irrigation system by the mast and / or by the trays, * replacement of the tray or the basin of a floor by an advertising element, lighting, Christmas decor or other, a sign, etc ..., this element can be hung on the connecting piece or pieces, * the trays are flared and their spacing along the mast allows the passage of light for the flowers and their development, 15 * possibility of festive equipment network.

  It will be understood that the basic hexagonal shape and the angular distribution with six holes on the different elements is a preferred form but not limiting.
