FR2520972A1 - Multiple flower pot support - has watering feed using hollow column on base to mount stack of coaxial conical pots - Google Patents

Abstract

The stand uses a hollow pivotable post (7) on a base to mount superimposed part conical flower pots (1) and incorporates a watering system, being designed to grow dwarf plants in compost (2). The plants grow in the perimeter zones of the pots which are secured axially on the post by retractable pins. A vertical gap between the bottom pot and the base allows each pot to be lowered in turn for maintenance, the gap thus moving up the post to give comfortable access to the axial area of the pot last lowered. Water may be fed (13) up the column to a header tank (16) and then through a down pipe (25) to each pot in turn. A passage equipped with a winch may be used to handle the pots, a double cantilever with a pulley on each end locating the return cable loop on the head of the post.

Description

The invention relates, by way of a new industrial product, to equipment for growing in stacked containers. The culture carried out according to this process applies to the generality of dwarf plants, these being able between flowers, fruits, vegetables and seedlings for the preparation of seedlings for transplanting.

saddle is characterized by the following facts: - Tapered tubs containing the soil are
superimposed. Culture takes place on the peripheral beach
overflowing from their summit.

- The bins are carried by a vertical column, in the
which they are engaged by a hub disposed in their axis.

- Watering is automatic. Water arrives in a tank
located at the top of the column by a tube housed in the co
lonne. A drip flow ensures the filling
sage, which became effective, is dumped on the beach of
culture of containers, from top to bottom, by a pierced tube
of holes.

- Comfortable access from inside the tanks, for tra
soil value or the removal of the crop, is done by
changing the level of the tanks. A bin location
empty at the bottom end of the column, is offset
successively from tray to tray from bottom to top.

- The assembly, column and bins, pivoting on the base, deter
undermine the uniformity of sunstroke.

- Cultivation can be carried out in a greenhouse, housing the whole
wheat in a shed, constructed of appropriate materials,
attaching from the bottom to the base and from the top to the column. Else
hand, a forcing can title given to the cultures by a wire
electric heater, placed inside the column.

- The handling of the tanks on the column is carried out by a
telescope, hanging on a rope, one end of which is
attached to a winch attached to the bezel. L rope
passes at the top of the column on two pulleys, located
respectively to the extracts of a horizontal beam,
whose median support is inserted for the occasion
on the upper end of the column.

 An embodiment of the assembly, in the form of a drawing, is annexed to this memo. Figure 1 is its vertical section. Figure 2 is a representation of the handling equipment.

 Ref to the drawing, the container (1), containing the soil, is tapered. the bottom of the tank (2), slopes gently towards the center, where the hub (3) is located, arranged in the axis of the tank. The bottom of the tank is drilled at the edge of the hub of holes (4), to remove excess moisture. Vertical cannulas (5) connect the upper side of the hub to the lower side. On the upper side, its inner and outer edges are raised and the channel (6), thus formed, collects excess water falling from the upper tanks, for flow from the bottom to the outside.

 The tanks are engaged by the hub on the tubular column (7). Their seat is a transverse pin (8), withdrawing for changing the level of the tanks. An intermediate washer (9) avoids a harmful effect on the tank. The column is engaged from below on the tubular journal (10), fixed in the center of the base (11). An intermediate ball stop (12) facilitates pivoting of the assembly, column and tanks. The interior of the column houses the irrigation water pipe (19) and possibly the electric heating wire for forcing (14). Both are suspended from the upper edge of the column and are supplied with water and electric current respectively from below.

 The number of stages that the set can include is undetermined. The location of a storey, in principle at the end, is empty (15), to allow, by individual descent of the tanks, comfortable access to the center, for work purposes.

 At the top of the column is the sprinkler tank (16). It is closed on the upper side by the cover (17). The cover has in its center a plug (18) which engages in the column. The cap has two axial grooves. The groove (19) houses the upper end of the water pipe. The groove (20) houses the upper end of the electric heating wire.

 The automatic sprinkler control elements are housed inside the tank. The extension of the pipe inside the tank is provided at its end with a drip spout (21). A flexible tube (22), making a loop in the horizontal plane, is fixed at its two ends, at a lowered point of the tank.

One (23) is open to the inside, the other (24) is connected to a fitting fixed in the wall of the tank. On the outside caté of the connection is connected the sprinkler tube (25). The middle of the loop is suspended from a top open float (26), located at the end of the pendulum (27), movable in the vertical plane on the yoke (28), attached to the tank. During operation, water drips into the tank. As the water level rises, the float rises, which controls the middle of the tube (22). Towards the end of the filling, the stop (29), blocked in contact with the tank, blocks the mounting of the flowing float, entraining the entire flexible tube underwater. From this moment, the water freely enters this tube and flows outwardly into the watering tube (25), which, pierced with a hole, sprinkles the cultivation areas. When the tank is empty, the siphon (30) empties the float, which will be ready for the next departure.

 The gripper of the containers is a telescope (D lle is constructed in a tube and made up of two semicircular branches, the four tangent bent ends of which (32) constitute the handles for manual handling. The close part of the handles is coated in a case. The case (33) is a hinge for the separation of the branches on the opposite side. The case on the latter side (34), is fixed to a branch, the other engages in it and locks by the pin (35). On the case (34), is fixed the winch (36).

On each side of the winch is a ratchet wheel (37).

 On one side, a lever (38), drives the winch by the pawl (39). At the opposite catd, the pawl (40) blocks the height of the tank. A rope (41) is fixed from one of its ends to an eyelet (42), located in the center of the case (33) and its other end to the winch. The rope passes at the top of the assembly on two grooved pulleys (43), located respectively at the end of a horizontal beam (44), the median support (45) of which is engaged in the column after removal of the plug (18).

 Of course, the invention is in no way limited to what has been the subject of the present description, the technical details may vary, without the idea of the invention, subject of this patent being altered.
