FR2692433A1 - Plant waterer, to give continuous and regulated water supply - Has reservoir of water, feeding into wick of fibrous material, which is contained in stabilising foot - Google Patents

Abstract

The watering device (1) is constructed on tank (2), fitted at the lowest point of the bottom (3) of the tank, with at least one opening (4), passing through to the external base (5) of the tank. The base (5) fits onto the stabilising foot (6), which is filled with fibrous material (7), and terminates at the lower end with a pointed penetration guide (8). The stabilising foot is designed with at least three wings (9), but generally four, linked together along the length of one of the edges. The wings have two faces (10) which are hollowed out and are packed with the fibrous material to give increased transfer surface to the soil. USE/ADVANTAGE - It gives improved stability in loose soil.

Description

CONTINUOUS WATERING DEVICE FOR PLANTS
The present invention relates to a device for continuously watering plants, comprising a reservoir and a stabilizing foot provided with a fibrous material.
French patent application n9l 10600 of August 26, 1991 relates to a device for continuous watering of plants comprising a water tank connected at its lower part to an axis, guide assembly, supporting a filter intended to be brought into immediate contact with the earth from sinking into the pot, 1 said filter con carrying two flat sides allowing the absorption of water and connected to a central part intended to be threaded on the axis and protected laterally by two plastic screens.

Such a device is easy to implement and is economical.

In addition, it offers great safety in use.

However, it has been found that this device when it was set up in loose soil could present a certain instability.

The present invention is therefore an improvement to the device described above and which makes it possible to obtain better stability, even in loose soil.

The invention therefore consists of a device for continuously watering plants (I) comprising, in combination, a reservoir (2), provided in its lower part with a bottom (3J provided with at least one opening (4) , connected by its base (5) to a stabilization foot (6) comprising an absorbent fibrous material (7) and ending in a tapered penetration guide (8), characterized in that said stabilization foot (6) comprises at at least three fins (9) connected axially to one another by one of their edges.

at least one of these fins has two partially recessed faces (10) enclosing said fibrous material (7), and said opening (4) is disposed above this fibrous material (7).

Other characteristics and advantages of the present invention are highlighted in the description below and the figures.

Figure I shows a top view in horizontal section of the device according to the invention.

Figure 2 shows a vertical sectional view of the device according to the invention.

FIG. 3 represents a stabilizing foot comprising 4 fins.

Figure 4 shows a device according to the invention buried.

Generally the stabilizing foot (6) has four fins (9). Each fin (9) may have two faces (10) partially recessed and enclosing said fibrous material (7).

Usually said partially recessed face (10) are grids, but it is especially important that the recessed faces allow direct contact between at least part of the fibrous material and the earth in which the stabilizing foot (6) will be pressed.

The reservoir (2) and the stabilization foot (6) are connected in a conventional manner, for example by screwing.

As it appears in FIG. 2, the bottom (3) of the tank (2) can be concave, the opening (4J of the bottom (3) is advantageously crossed by a tube (II), rigid or flexible, the at least one of the ends is flattened and which encloses a halyard (I2).

Usually the halyard (12) comes out slightly / flush with the lower end of the tube (II) and is located at a distance from the fibrous material (7). Preferably the halyard (12) is made of synthetic material, generally polyester. Usually the size of the halyard is between 1 and 5 cm.

The fibrous material (7) is preferably a water-absorbent fabric advantageously made of a permeable synthetic material.

The tank (2), as well as the fins (9), whether their two faces are hollowed out or not, are preferably made of plastic material.

The reservoir (2) is advantageously provided with a cover (15) pierced with one or more holes and can comprise a double wall (r3,14).

The cover (I51 can itself be formed from a double wall.

Generally, the tank has a capacity of 0.5 to 10 liters.

With a view to continuous watering of plants by means of the device of the invention, the stabilizing foot (6) is pricked into the ground (16), near where the plants (I7) to be watered.

Thanks to the penetration guide (8J tapered, the stitching in the ground is done without difficulty. The tank (2) is filled with water or an aqueous solution; such as for example an aqueous solution of mineral salts.

The water or the aqueous solution flows drop by drop through the opening (4J at the bottom (3) of the tank (2).

The drops of liquid fall on the fibrous material, enclose it in at least one of the fins (9).

Generally, the fibrous material slightly exceeds the upper edge of the fin (9) holding it, so as to best capture the drop of liquid falling from the reservoir. This liquid propagates along the fibrous material and then comes to moisten the earth which is in contact with it.

It is particularly advantageous for the opening (4) of the bottom (3) of the tank (2) to be crossed by a tube enclosing a halyard (12).

In fact, the halyard (12), the upper end of which is in direct contact with the liquid from the reservoir (2), greatly facilitates the controlled and drop-by-drop supply of the liquid to the fibrous material (7).
