Description

Title of the invention

Method of making an ornamental horticultural pot

Background of the invention

The present invention relates to the general field of horticultural pot manufacturing processes.

Horticultural pots are generally made from materials that can be liquefied to be molded using a mold and an injection process. Various other ways of making horticultural pots are known, using pottery, faience, etc. There are also ornamental horticultural pots, made from wood or metal curved and welded to form a pot.

The invention is concerned with the manufacture of ornamental horticultural pots quite original.

Object and summary of the invention

The present invention therefore aims to allow the manufacture of original ornamental horticultural pots and quite identifiable by their constituent characteristics that give them an aesthetic appearance quite interesting.

The invention therefore proposes a method of manufacturing an ornamental horticultural pot comprising the steps of:

positioning and stacking wall stones against the inner walls of a mold of a predefined shape corresponding to an external shape desired for the horticultural pot,

- Distribute a pasty connecting element on the bottom of the mold and against the inner wall formed by the stack of stones to a thickness respecting the thickness ratio on the height of the pot between 1/10 and 1/5,

placing, before the preceding step or just after, by perforation of the pasty connecting element, at least one piece of clearance of an orifice at the bottom of the mold, this orifice serving for the evacuation of the water, this piece having a height greater than the thickness of the pot bottom envisaged,

- Observe a drying time of the pasty connecting element allowing it to become solid, - take out the horticultural pot obtained from the mold.

With such a method, it is allowed to obtain a pot giving the appearance of a stone wall on its outer face. This is particularly aesthetic. Indeed, it is now possible to define a growing area with a stone wall, which is generally appreciated. Such a construction is however not accessible to date without masonry work. The invention makes it possible to obtain a marketable pot as such and conferring precisely this aesthetic without any masonry being made by the purchaser of the ornamental horticultural pot obtained with a method according to the invention. Any form of mold for erecting a wall against the wall of the mold can be used to implement the invention. Including round molds, so circular, square, oval, rectangular, flared or not, ball etc. may be used. This allows to make jars forms quite diverse and varied, while keeping the aesthetics of the wall obtained according to the invention on the outer face of the pot.

The invention therefore makes it technically possible to obtain a pot having the structure and appearance of a wall, which is quite original.

Note that for reasons of practicality of implementation of the process, silicone gel or the like can be used at the time of stacking stones. This has two roles: as the stones are stacked without any binder, this ensures a minimum of maintenance between successive levels of stones. In addition, it allows to seal between the stones after distribution of the concrete without having to perform the joint after extraction of the pot of its mold. Nevertheless, with or without the use of a silicone gel, it may be useful to seal with a pool adhesive. It is noted here that, nevertheless, this step is not essential.

In one embodiment, distinct from the previous one, but also under the principles of the invention, the ratio thickness to height of the pot is between 1/30 and 1/10.

Such a particularly low ratio has been observed accessible by the inventor following the production of high pots. It also observed that a pre-cutting of the stones used made it possible to reduce considerably the thickness of mortar used. This feature allows to obtain low mass pots which is very advantageous for transport and handling.

Thus, with this embodiment, the pasty connecting element is always distributed against the internal face of the stones stacked in the mold. This distribution of the pasty connecting element against the previously stacked stones is the originality of the invention. Indeed, inside the pot finally obtained, the stones are no longer visible and are separated from the earth placed in the pot by the pasty element.

This therefore allows a very particular manufacture of a pot according to the invention devoid of connection element manipulation in the first step of stacking stones. The pasty element intervenes only in a single subsequent step and it contributes to the sealing of the pot and the isolation of the earth with the stones constituting the pot. It is noted here that one or two layers of indoor and / or outdoor water repellent will be used. This helps to seal the pot. The advantage of the invention is that the pot has, on the inside, a uniform surface pasty element. This makes it easy to perform any concrete treatment without having to treat the stones themselves.

The distribution of the binder by the inside of the mold and on one side of the stones allows to obtain, if necessary, a beautiful aesthetic rendering where the binder does not appear in a bead between the stones visible from the outside. The distribution of the binder on the inner walls allows a partial penetration of the binder between the stones to a depth allowing the maintenance of the stones with each other. By default, the binder does not penetrate sufficiently to reach the mold and is therefore not visible from the outside.

Thus, by applying the principles of the invention, pots can be made with stones with a thickness of 1 to 10 centimeters and a binder distributed over a thickness ranging from 1 to 11 centimeters. It is noted here that, in the case of thin stones, it may occur that the binder is visible from the outside. Pots up to 1.8 meters high can be obtained with a binder thickness of 6 centimeters which is sufficient to ensure the mechanical strength of the pot on such a height.

According to a particular characteristic of the invention, the pasty bonding element is chosen from mortars, adhesive mortars, concretes, cements, coatings, fibered adhesives.

These materials allow after drying to obtain a very good performance of the pot because are quite suitable for ensuring a connection between the stones of a stack as realized according to the invention.

Advantageously, the method comprises an intermediate step of arranging one or more structures (s) metal (s) against the inner wall thus formed and / or the bottom of the mold before the distribution of the connecting element.

This characteristic makes it possible to increase the resistance of the pasty connecting element.

In some cases, the presence of metal in a mortar or concrete avoids the appearance of cracks.

The metal structure is selected from fences, crossed iron bars, interwoven metal cables.

Advantageously, the pasty connecting element is distributed over a thickness of between 1/8 and 1/7.

With such a thickness, it is ensured that the ratio between the height and the thickness of the pot gives a sufficient mechanical strength to the entire pot. However, there is sufficient space in the pot to allow cultivation.

According to a particular characteristic, a section of pipe then left permanently in the pot is used as a clearance part of an orifice.

The use of such a piece of clearance of an orifice is advantageous because, once the pasty connecting element is distributed, no other operation is required to obtain the pot with a bottom hole allowing evacuation of water.

According to another particular feature, a solid or hollow cylindrical piece then removed to clear the hole at the bottom of the pot is used as a clearance part of an orifice.

This characteristic implies that a complementary operation is performed, following the distribution of the pasty bonding element, this operation consisting of pressing and then removing the cylindrical part of the bottom hole for the evacuation of water. However, this makes it possible to reuse the cylindrical part.

Advantageously, the method comprises a step of jointing with watertight joints after leaving the mold to seal the pot. The joints can be colored which can allow various types of finishes.

This step ensures a good seal of the mold at its side walls. This step may also make it possible to confer a better aesthetic ornamental horticultural pot obtained by a process according to the invention.

According to an advantageous characteristic of the invention, the method comprises a step of positioning at least one structure forming arches or allowing diametrically opposite arches to be installed after the step of positioning the stones and before the step of distributing the stones. pasty connecting element.

Since the pasty connecting element may be a heavy material, as well as stones, it is indeed useful for the pot to include means to be easily lifted and moved. For this, suitable equipment may be used in combination with the hoops thus formed. With this feature, it is also possible that a simple bar is placed in the two arches to lift the pot to two people placed on either side of the pot. Wire ropes protruding from the barrel pot may be cast into the pasty connecting member or screw-in inserts may be planted in the pasty bonding member prior to drying and curing. Arches bearing complementary threads can then be screwed and unscrewed on these inserts.

Advantageously, the step of positioning a structure with arches or for installing arches is such that this structure is placed between the metal structure and the wall obtained by the stack of stones against the inner wall of the mold.

This allows the arch structure to be trapped between the stone wall erected against the mold wall and the grid. It is thus ensured that, during the distribution of the pasty connecting element, the arch structure is well trapped within the pasty connecting element. According to an advantageous embodiment, the structure making at least two hoops is a metal cable.

This ensures a good resistance of the arches and a possible flexibility of the arches. In addition, the use of metal is particularly suitable in the context of the use of the pasty connecting element. The wire rope is typically a braided wire rope.

According to one particular characteristic, the method comprises, at least before the distribution step of the pasty connecting element, a step of disposing at least one electric cable running from the bottom to the top of the mold and opening outwards the pot at the top and bottom of it after distribution of the connecting element.

According to one particular characteristic, the method comprises, at least before the step of distributing the pasty connecting element, a step of disposing at least one pipe running from the bottom to the top of the mold and opening out of the mold. pot at the top and bottom of it after distribution of the connecting element.

These last two steps can be performed simultaneously at the step of stacking stones. The introduction of the cable or pipe will in any case be performed before the distribution of the pasty connecting element. The cable or pipe will then be trapped in the binder after its distribution. It will include a low connection device for connection to an electrical or water supply network and a high connection device for connection to a lamp or spray nozzle.

The invention also relates to an ornamental horticultural pot obtained by a process according to the invention.

The stones used in the manufacture and in the ornamental horticultural pot obtained can be chosen from marble pavers or slabs, terracotta pavers or slabs, pebbles, natural stones, synthetic stones, blocks, earthenware tiles, tiles.

We see here the advantage of the invention which makes it possible to obtain a great diversity of the external appearance of ornamental horticultural pots obtained according to the invention, while retaining the same manufacturing method according to the invention and the same general structure for the ornamental horticultural pot obtained.

In a particular embodiment of the invention suitable for pots of large size, the pot is formed of at least two parts, a first so-called low part obtained according to a method according to the invention and comprising a bottom and at least one second annular portion without bottom obtained by a method according to the invention with a release piece for clearing the bottom of this second part.

Such an embodiment makes it possible to easily transport and handle the parts of the pot before forming the final pot at the place of its installation. The thickness-to-height ratios are then respected for each of the pot parts independently.

Detailed description of an embodiment

Figure 1 shows a mold M of an ornamental horticultural pot used in a method according to the invention. Typically, it may be a pot made by molding, for example from a plastic material. This type of material is particularly advantageous because it does not stick with the pasty binding elements that can be used. If in doubt about this, oil can be spread on the inside of the mold to avoid adhesion.

The bottom of the mold is full but it is also possible to consider an open mold bottom. In this case, the open bottom mold is placed on a support forming a bottom of the mold M.

In FIG. 2, an intermediate moment of the step of positioning and stacking stones P in the wall against the inner wall of the mold M is shown. The invention uses P stones which can be slabs of natural stone or synthetic stone or pavers of marble, terra cotta, etc. We also note here that other types of molds M, for erecting a wall against the inner wall of the mold M, may be considered to implement the method of manufacturing an ornamental horticultural pot according to the invention. Aesthetic molds, the section of which has one or more curvatures, example ball, can be used for the implementation of the invention, since the stack of stones P in the wall against the wall of the mold is possible.

FIG. 3 shows the end of the step of positioning and stacking the stones P against the inner wall of the mold M. At the end of this step, the pasty connecting element can be directly distributed on the internal face of the wall erected in the mold M.

FIG. 4 shows the result of the optional step of positioning a metal structure, here a grating G, against the inner wall formed against the inner walls of the mold M. The presence of such a metal structure in a connecting element pasty type concrete avoids cracks.

Figure 5 shows the introduction, also optional, between the mesh G and the stone wall P, a cable C arching. Here, the cable C carries a first arch A on one side of the pot. An identical structure in wire rope is installed on the diametrically opposite side so as to make a second arch A on the top of the pot.

FIG. 6 shows the step of depositing metal structures F on the bottom of the mold. The presence of such metal structures that intersect and are entangled increases the strength of the final pot.

FIG. 7 shows an intermediate moment of the step of distribution of a pasty binding element B following the distribution thereof on the bottom of the mold and the introduction by depressing clearance pieces T of an orifice at the bottom of the mold M. The release pieces may be pieces of pipe T placed vertically at the bottom of the mold planted in the thickness of the pasty connecting element B and intended to remain permanently in the pot once the element Bond B dried. Another embodiment uses at least one cylinder T pressed successively into the pasty connecting element B at the three locations. The cylinder is then removed leaving an orifice in the pasty connecting element B distributed at the bottom of the mold M. Then the distribution step of the pasty connecting element B is performed on the inner face of the inner wall. When the pasty connecting element has a high fluidity, a mold Inside is placed to make internal formwork and maintain the connecting element during its distribution along the internal walls erected with the stones. In the case of a pasty connecting element having a reduced fluidity, it is plastered on the inner wall erected inside the mold.

FIG. 8 shows the inside of the pot obtained after distribution of the pasty binding element B against the stone wall P formed by pressing against the interior walls of the mold M. At the bottom of the mold M, there are three orifices 0 which correspond to the three pieces of pipe T planted on the bottom of the pot.

FIG. 9 shows the ornamental horticultural pot as obtained according to the invention, on which the stones P on the outer wall appear, the pasty connecting element B inside the pot and the two arches A allowing lift and move the ornamental horticultural pot obtained according to the invention. Advantageously, the horticultural pot obtained is covered with a layer of water-repellent material to protect it. This makes it possible to preserve the natural state of the stones and in particular to avoid that they darken over time.

It is noted here that Figure 9 is schematic and shows a pot on which the stones are even and uniform on the outer face. In reality, the stones will not be very straight and uniform as shown in the photo proposed in Figure 10. Thus, the outer rendering is all the more enjoyable that the stones used will recall the appearance of a wall of real stone.

Finally, we note that various implementations can be made according to the principles of the invention. In particular, feet, typically up to 5 feet, can be installed under the pot. The mold used will then present the embossings corresponding to the feet on its bottom. The feet will be molded by distribution of the concrete on the bottom of the mold. Advantageously, light concretes, for example of the "perlibeton" type, will be used in pasty bonding elements.

The pots may be provided with various types of handles, including handles smaller than that presented in the achievements presented, or, for the little ones, to be deprived of them. Retractable rings can also be installed. Optionally the upper contour of the pot may have finishing stones.

For the convenience of transport, pots divided into several parts of which annular parts may be manufactured according to the invention. This amounts to making a pot according to the method described and to add, above, a pot made similarly but without distributing the pasty element on the bottom of the mold.

Pots with open bottom can also be made. In this case, a clearance piece of the size of the bottom of the pot is used before the distribution of the pasty element. It is also noted that this clearance piece can be omitted when it is possible, given the quality of the pasty element, to distribute it on the inner wall without invading the bottom of the mold. Note that the principle of the invention will still be used in such a case.

Finally, it is noted that optionally lighting and / or watering devices can be integrated into the structure of the pot.

Thus, before the distribution step of the connecting element, as shown in FIG. 11, electrical cables CE will advantageously be placed against the inner wall formed by the stacked stones. These cables open at the top and bottom of the mold to remain accessible after the distribution of the pasty connecting element on the inner wall. The electrical cable CE ends, at its upper end, by a connection device BE for, typically, the connection to a lamp.

Figure 12 shows a similar embodiment with TA watering pipes also placed before the distribution step of the connecting element. These garden hoses advantageously comprise spray nozzles BA at their upper end.
