The present invention relates to a plurality of parts incorporating coupling and assembly elements in each of them for “weaving” or forming plastic fabrics with a variety of structural designs of shape, size, color, etc., which are useful in the furniture, decoration, and architecture sectors. Particularly, the coupling and assembly of the parts are achieved thanks to the configuration of their male and female locking means that are coupled together in a rotating way and secured by means of fastening elements; resulting in a plastic fabric with great structural resistance to the weight applied and to the environment.
Within the furniture industry, there is a need to manufacture furniture with characteristics of high resistance to outdoor conditions and use, based on a frame structure with a variety of aesthetic designs that do not imply the need to use a diversity of materials and resources.
Currently, there are pieces of furniture made from a frame and various parts that require a variety of other special joining parts for the coupling of the other pieces, and thus be able to form plastic fabrics, also referred to herein as “meshes” that are used as structural elements in the manufacture of furniture, for example, in chairs as back elements, support elements or seat elements. However, these meshes become brittle over time because the structural strength of the mesh is mostly concentrated in the joining parts, causing cracks that eventually lead to the total disposal of the piece of furniture.
Although this can result in the generation of meshes with characteristics suitable for installation on frames, this has the disadvantage of requiring additional elements for the assembly of the mesh with the frame, which complicates the final assembly of the furniture because other types of fastener elements are necessary as well as the use of specific tools.
Thus, there are a variety of plastic fabrics for obtaining meshes used in the manufacture of furniture. However, other problems related to meshes in the prior art are special fabrics that are manufactured from PVC material threads, where a person weaves the fabric on the same frame without the need for additional elements that act as coupling or joining means. However, factors such as labor, design as well as the time required to manufacture them increase costs. In addition, the strength characteristics of PVC thread are considerably affected by the environment within which it is exposed. (This would be removed as PVC holds up really well to exposure to the elements)
Thus, there is no known system and method of plastic fabric formed from a plurality of plastic injection molded parts that are assembled or “woven” in a rotational manner with one another without the need for special tooling or other materials as opposed to what is known in the prior art.
For instance, Mexican Patent 322495 discloses a multi-layered support structure that provides ergonomic and adaptive seating support; the multi-layered support structure includes multiple cooperative layers to maximize overall comfort and support while improving adaptation to localized variations in a load, such as in the load applied when a person sits in a chair; each of the cooperative layers includes elements such as pixels, springs, support rails and other elements to provide this adaptive comfort and support; the multi-layered support structure also uses aligned material to provide a flexible yet durable support structure; accordingly, the multi-layered support structure provides maximum comfort for a wide range of body shapes and sizes. The foregoing Mexican patent is considered to solve comfort problems. However, in order to achieve its purpose, it uses an endless number of elements, so it cannot be used to form meshes of elements.
On the other hand, U.S. patent application US2011250009 discloses a reconfigurable furniture apparatus including a hinge assembly. The hinge assembly includes a plurality of link plates each comprising at least two parallel flat surfaces and at least one bore extending through the flat surfaces. A connecting rod extends through holes in the flat surfaces that provide an axis of rotation for the connecting plates. Two end caps are attached to the coupling rod ends, where the end caps are operable to create a tensile force along the connecting rod to provide a degree of resistance to rotation between the flat surfaces of the link plates. The means join at least two joining assemblies in which the positions of the connecting plates are reconfigurable to form furniture. It should be noted that, in this structure, the rods have the function of securing the other parts and are installed with the help of tools.
Finally, U.S. Patent U.S. Pat. No. 8,834,975 discloses a modular block system consisting of a plurality of puzzle-type and independent block elements for forming furniture, table, wall, and floor coverings. Nevertheless, securing the blocks is achieved through magnetic elements or magnets, where the resistance of the system depends on the magnetic attraction force.
It is known to those skilled in the art that there is a need for mesh methods and systems where the parts themselves comprise coupling and securing means which hold the parts together uniformly and thereby form meshes that can be assembled into frames of chairs, benches, beds, etc. There is also a need for a novel configuration of parts for the assembly of the woven mesh with a furniture frame.
The present invention seeks to provide parts that together, by means of novel locks, can form meshes that can be coupled to frames.
In accordance with the present invention, the main object of the present invention is to provide a plastic fabric system comprising a plurality of parts that are coupled to each other.
A second object of the present invention is to provide parts with coupling and assembly elements incorporated in each part to “weave” or form meshes with a variety of structural designs with both load-bearing capacity and flexibility.
A third object of the present disclosure is to provide a plastic fabric system where the parts comprise rotatable locking elements that can only be assembled and released in a single position without the need for special tools.
A fourth object of the present disclosure is to provide a plastic fabric system wherein the locking elements of its parts comprise female locking means and male locking means.
A fifth object of the present disclosure is to provide a plastic fabric system in which the parts can be of different colors so that woven meshes with visual patterns can be created to the user's liking.
A sixth object of the invention is to provide a method and plastic fabric system for manually forming meshes so that even a user can assemble and attach the mesh(es) to the frame of a piece of furniture after shipment or delivery.
A seventh object of the invention is to provide a plastic fabric system to obtain final parts that are easily attached to a frame and that, by being generated through a plastic injection process, advantages in manufacturing times, costs, homogeneity in their molding, and high resistance to weathering may be obtained.
Accordingly, the embodiments of the invention comprise a combination of features and advantages that substantially improve the fabrication and structure of plastic fabrics known in the art. These and various other features and advantages of the invention will be readily apparent to those skilled in the art by reading the following detailed description of preferred embodiments of the invention and referring to the attached drawings.
For a detailed description of the preferred embodiments of the invention, reference will now be made to the attached drawings, where:
Firstly, it should be clearly understood that similar reference numbers are used to identify the same elements consistently in the various figures since such elements can be explained or described in greater depth throughout the complete written specification, of which this detailed description is an integral part.
The embodiments described herein comprise a combination of advantages and features intended to address various deficiencies associated with certain prior devices, systems, and methods. The foregoing has more broadly outlined the characteristics and technical advantages of the disclosed embodiments so that the detailed description that follows can be better understood. The various features and advantages described above, as well as others, will become apparent to those skilled in the art once the detailed description has been read and by consulting the accompanying figures. It should be noted that the design and specific embodiments disclosed can readily be used as a basis for modifying or designing other parts to accomplish the same purposes as the disclosed embodiments.
As used herein, for the manufacturing of furniture it is necessary to use plastic fabric meshes of a rotary assembly comprising parts that are joined by means of first locking elements and second locking elements (male and female), which can be used in the manufacture of meshes comprising parts of greater strength at the joints and that are easy to assemble. As is the case of the present invention, the parts comprise a secure and easy-to-put-together assembly without the risk of the parts coming loose.
In the field of furniture design, there have been a number of disadvantages with respect to the state of the art since, in the first place, there are no parts that can be directly coupled together to form a mesh, so there is no possibility that they can be assembled by means of locks attached directly on the parts.
In this respect, the present invention comprises a series of parts consisting of and utilizing male locking means and female locking means, wherein these means can be assembled (knitted) in such a way that they can be mounted on frames and can be color matched, which in turn ensure a perfect coupling between parts. Among the materials used, polymers that confer strength to the mesh are preferred. However, it is possible to use any type of material that can be processed to form the parts.
The parts described below are made up of male and female locking means, which are common to all parts, and which vary in quantity and/or are omitted depending on the part described.
The female locking means (2) of the first part comprise on the outside a front face and a rear face which are limited at each end by a rounded side face. In the first part, there are two female housings for the preferred embodiment, without being limited to this amount, which can receive two male stems. On one of the side faces there is a guide point (2a) that will be used to couple the parts. The female locking means (2) in the interior comprise female housings (2g) defining cylindrical perforations wherein the interior comprises first projections (2d, 2e and 2f) which have the same distribution as recesses (1b, 1c, and 1d) in the male locking means, such that there is an angle (a) of 145°, an angle (β) of 145° and an angle (γ) of 70°; likewise, the interior comprises second projections (2c) which are smaller in size than the first projections (2d, 2f, and 2e) and which in turn have angles (θ) and (λ) of 120°. In order to have a better part strength, there is a reinforcement zone (1j) in the transition zone between the female locking means (2) and the male locking means (1) while in the intermediate part, between each male member set (1) and female member set (2) there is an intermediate reinforcement zone (1k) which starts from the transition part of the male member (1) with the female member (2) and which runs towards the lower area of the part forming an intermediate reinforcement zone (2k). As it can be appreciated, the reinforcement zones allow having solid parts that, when the mesh is being formed, said mesh is resistant to use.
The female locking means (3) of the second part comprise on the outside a front face and a rear face limited at each end by a rounded side face; on this second part two female housings (2g) are formed, which can receive two male stems.

In order to have a better part strength, there is a reinforcement zone (1j) in the transition zone between the female locking means (2) and the male locking means (1); while in the intermediate part between the male locking assembly (1) and the assembly means (5), there is an intermediate reinforcement zone (1k) which starts from the middle portion and runs towards the lower portion of the part. As it can be appreciated, the reinforcement zones allow having solid parts that, when the mesh is being formed, said mesh is resistant to use.
The second portion of the fourth part relates to an assembly means (5) which serves to couple to a frame, this assembly means (5) may be but is not limited to a coupling cylinder (5) which comprises an inner diameter (5a) which is completely hollow in order to be able to insert a frame which is preferably cylindrical. It is important to mention that in the preferred embodiment there is a cylinder. However, this fourth part may comprise a different shape, which will be coupled to the shape of the frame.
The female locking means (2) of the fifth part comprise a cylindrical shape on the outside; in the fifth part, there is a female housing that can receive a male stem and an assembly means (6).

The female locking means (2) inside define a female housing (2g) comprising first projections (2d, 2f, and 2e) which have the same distribution of the recesses as the male locking means, such that there is an angle (α) of 145°, an angle (β) of 145°, and an angle (γ) of 70°; likewise, the interior comprises second projections (2c) which are smaller in size than the first projections (2d, 2f, and 2e) and which have angles (ε) (θ) and (λ) of 120°. In order to have a better part strength, there is a reinforcement zone (1j) in the transition zone between the female locking means (2) and the assembly means (6). As it can be noticed, the reinforcement zones allow having solid parts which, at the moment of forming the mesh, said mesh is resistant to use.
