MOVABLE CONTAINER FOR FLOWERPOTS Filed April 1, 1969 I I Imam States Patent Oflice 3,528,676 Patented Sept. 15, 1970 Int. Cl. B62b 1/26 U.S. Cl. 28079.2 4 Claims ABSTRACT OF THE DISCLOSURE The flowerpot container consists of a lower first component disc-shaped made of metal and combined with a number of castors, a upper second component presenting a bottom surface, an inner first mantel projecting upwards from said bottom, an outside mantel depending towards the floor from the upper mentioned mantel so as to conceal said castors, an axial projection formed from the bottom surface of said upper component, said bottom surface presenting upper ribs adjacent to the flowerpot and peripheral lower ribs abutting against said first component, clamping means to connect said two components against the elastic reaction of said ribs against the adjacent surface of said first component.
BACKGROUND OF THE INVENTION This invention is concerned with some improvements related with movable containers or movable stands for flowerpots. Such containers are provided with castors so that the flowerpots may be displaced without the necessity of raising the same from the floor.
An object of the invention is to facilitate the mounting and therefore to minimize the price of such containers now so popularized for the evident advantages deriving from their use.
Another object is to improve their operativeness with respect to the plant of the pot.
A further object is to provide a container that is shaped to conceal the provision of the castors so that the container presents the appearance of a conventional stand:
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an axial sectional view of flowerpot container with castors according to a first embodiment of this invention; and
FIG. 2 shows as FIG. 1, partially a modification thereof;
FIG. 3 discloses schematically the elastic reaction during the coupling step of the said two components.
DETAILED DESCRIPTION The container according to this invention consists of a upper component 1 made of plastics material and of a lower component generally referenced 2. The upper component 1 presents a bottom section from which a number of upper ribs 11 projects towards the adjacent bottom of a (not represented) flower pot. By this way of gap G is defined operating as ventilating chamber and collection of water. The bottom 10 presents a frustum cone first inner mantel 9 directed downwards namely towards the floor 17, the second mantel 7 being spaced with its lower rim 16 from the floor 17 of about few millimeters as shown on the drawings so as to conceal the castors 14 mounted to the lower component by means of the plates welded or otherwise fixed to the lower component.
The upper component is formed with a number of a second set of peripheral lower ribs 12 depending downwards and abutting against the adjacent surface of the lower component 2, the latter being made of metal or like material.
According to the invention there are provided central clamping means of the two components, said, means consisting in the embodiment of the FIG. 1 of a central projection 4 moulded from the bottom 10 wherein a screw 3 is embedded during the moulding of the component. Since the ribs 12 projects from the lower surface of the bottom 10 more than the projection 4 it is clear (FIG. 3) that when a mutter 6 is threaded to the screw 3, after insertion of the washer 5, an elastic deformation takes place that secures a permanent clamping of the two components.
A third set of ribs 13 are formed between the two mantels so as to stiffen the support structure of the upper component.
The embodiment according to the FIG. 2 shows a polyhedric projection 4a that is housed into a complementary depression 21 of the metallic component 2 so that a relative motion of the two components is prevented. The projection 4a presents a cylindrical extension 3a, with an annular groove so as to fit an elastic washer 5a. The elastic coupling takes place according to the same principle as shown by the FIG. 3.
Although a preferred embodiment of the present invention has been shown and described, it will be understood that various changes and modifications may be made in the details thereof without departing from the spirit and scope of the appended claims.
Having described the invention, what is claimed is as follows:
1. A flowerpot container consisting of a lower first component disc-shaped made of metal and combined with a number of castors, a upper second component presenting a bottom surface, an inner first mantel projecting upwards from the said bottom, an outside mantel depending towards the floor from the upper mentioned mantel so as to conceal said castors, an axial projection formed from the bottom surface of said upper component, said bottom surface presenting upper ribs to be adjacent to the flowerpot and peripheral lower ribs abutting against the said first component, clamping means to connect the said two components against the elastic reaction of the said ribs against the adjacent surface of the said first component.
2. A flowerpot container according to the claim 1 wherein the clamping means consists of a screw embedded into the said axial projection and cooperating with a nut and an elastic washer.
3. A flowerpot container according to the claim 1 wherein the clamping means consists of cylindrical extension of the said axial projection provided with a toroidal groove, and of an elastic washer cooperating with the said groove so that to stop and lock the said two components with one another against the elastic reaction of their abutting surfaces.
4. A flowerpot container according to the claim 3 wherein the said axial projection is polyhedrically shaped and the said second component presents a depression complementary to the said axial projection so as to prevent any relative movement therebetween.
