Description

MODULAR SUSPENSION SYSTEM FOR PADDED PRODUCTS

TECHNICAL FIELD OF THE INVENTION

The field of application of the present invention relates to the comfort and rest industry dedicated among others to the manufacture and marketing of padded products. Specifically, the present invention relates in one of its preferred embodiments to the mattress industry.

BACKGROUND OF THE INVENTION

The present invention relates to a novel modular suspension system for padded products, such as mattresses, cushions, seats, upholstery, furniture, footwear, among others.

The preferred embodiment of the present invention applies this modular system to optimize and make flexible the manufacture of mattresses. Likewise, the modular system of the present invention facilitates the transportation of said padded products. In addition, this invention improves user comfort at the time of use, thus obtaining an ergonomic benefit. Finally, the present invention provides a product with greater performance and durability.

There is a great variety of systems in the State of the Art that deal with the elaboration of products of this type. Some of these systems and their components are presented below.

European patent application No. 1 046 361 mentions an elastic support arrangement for mattresses, bed bases, seats or other upholstery furniture that has: an upper padded layer, a lower padded layer, a spring of plastic material with truncated cone shape placed between the two layers characterized in that the spring comprises at least two equidistant helical with a trapezoidal, an upper ring at one end of the coil and a lower ring in the ^'other end of the coil cross section. Said invention suggests that the arrangement of the springs be carried out in rows alternating one upside down and the other upside down. As can be seen from reading this document, the arrangement does not provide more information about other components or their interaction to form a system that improves the production of the mattresses known at that time.

German patent DE 2015659 protecting a spring-based arrangement of a synthetic material bonded together for mattresses or other upholstered furniture; It has spring elements and connecting bridges. In this document it is suggested that said springs be made of a synthetic material with isotopic radiation to adapt the spring force of each element and therefore vary the total effect of the filling according to the needs. Additionally, these springs can have different shapes - like helical, arcs, ^λλ X "shape, waves, series triangular, etc. Finally, said springs are connected, both along and across the arrangement, through the connecting bridges. Based on the above, this arrangement presents several disadvantages such as: the difficulty of the isotopic radiation process to vary the material properties of the springs, the diversity of spring forms that hinder their manufacture and the need for joining bridges that make the whole arrangement difficult. US Patent 5,588,165 protects a padded assembly comprising: a base consisting of a plurality of springs where each spring has a compressible elastic portion, a spring base and a support plate. This base is formed by means of parallel slats on which rows of springs are mounted. It also protects the use of hinges between the slats of the base to adapt it to different parts of the body. This patent has two main disadvantages: the first is that the spring has a base, body and plate in the same piece, which makes it difficult to manufacture. The second is the low flexibility in production: the arrangement due to the use of parallel slats in rows.

US Patent 6,427,990 protects an arrangement of individual springs that have a base ^: an independent body and an upper plate, wherein said body is spherical and is formed by doubles of ^; cushion arms. In addition, the body has means of union to couple the spring body with the base and the top plate. Additionally, the patent contemplates the use of connecting arms that are attached to the upper plate of the spring to assemble the individual springs in a rectangular arrangement. A disadvantage presented by this patent is the complexity of manufacturing the spring body. Another disadvantage is that the connecting arms can break easily when the upper plates are misaligned due to the pressure exerted by the user on the mattress.

US 6,477,727 protects a spring element used in padded furniture consisting of a base and a support plate, characterized in that the body ¹ of the leaf-shaped spring is located between the base and the plate, being no less than three and no more than four leaves per spring and separated by equal angles. These springs have means; of compensation that allow to adjust the height of the support plate. Each spring element is joined by its base to a grid of grid crossings to form the arrangement; of the mattress. This arrangement is wrapped at its periphery by a frame whose lateral stringers are joined by slats on which the spring elements described above are placed. This patent has the disadvantage in the difficulty of manufacturing the leaf shape of the springs and the little flexibility due to the use of the crosshead network to assemble the arrangement. International patent application no. PCT / FR2005 / 050146 refers to a mattress housing that has a support sheet where the base of the springs of a flexible material are connected. The springs are cup-shaped and can be formed by one or two cups so that they can be directed to one side or both sides of the mattress, respectively. A disadvantage of this patent is the complexity of the manufacture of spring in the form of one or two cups. Another disadvantage arises in the spring mode with two cups because the arrangement is joined by means of a plate placed in the intermediate part of the springs, where both cups are joined, and a breakage of the plate can easily occur during The use of the mattress. ^' . As can be seen from the previous reading, it exists in the

State of the Art the need for a suspension system to form arrays or modules usable in padded products, which makes their manufacturing more flexible. There is also a need for an easily assembled system whose components are made of a flexible and lightweight material. It is also desirable that said modular suspension system can be ergonomically adapted by zones and in different types of products.

DETAILED DESCRIPTION OF THE PREFERRED MODE

The preferred embodiment of the present invention is shown in Figure 1. The invention consists of a modular suspension system (10) for padded products which is composed of one or more modules (15). Each module comprises a modular base (100) formed by a plurality of cells (110), one or more elastic elements placed on each cell (110) and a cover that connects to the top of each elastic element, to form sub-assemblies. The components of each sub-assembly vary according to their position within the modular suspension system (10). Subassemblies can be of three types: intermediate subassembly (20), end subassembly (30) and corner subassembly (40) as illustrated in Figures 15, 16 and 17 respectively. The intermediate sub-assembly (20) is formed by an intermediate cell (110) within the system, a helical spring (200) and an intermediate cover (300). The end subassembly (30) is formed by a cell (110) located along the periphery of the system, a helical spring (200), one or more additional elastic elements (250) and a cover of extreme (330). Finally, the corner subassembly (40). It is formed by a cell (110) located in the corner of the system, a helical spring (200), one or more additional elastic elements (250) and a corner cover (360). In figures 2 to 4 the preferred embodiment of the modular base (100) is observed, where each cell (110) is formed by three or more walls. In the illustrated embodiment, the cells (110) preferably have an octagonal shape in which four adjacent walls are shared with adjacent cells and four non-adjacent walls form part of the diamond-shaped intracell spaces. The walls that form each cell (110) have in their upper part receiving means for one or more elastic elements, according to their position within the modular suspension system (10). In the preferred embodiment, the receiving means preferably consist of three substantially cylindrical protruding spring recipients (111), located at equidistant distances. Each spring receiver (111) is inserted into connection means located at the lower end of the helical spring (200). Additionally, the receiving means also consist of four securing means (112) which are a pair of coupling tabs, located at equidistant distances, to stop the lower end of the helical spring (200). A side cut of a tongue of the securing means (112) is illustrated in Figures 22A and 22B. The cells located at the end of the base (100) of the module (15) that does not connect to other modules have one or more additional receiving means (113), which preferably consist of one or more square receivers from which the interior can be received connecting means of one or more additional elastic elements (250). In addition, each cell has a directional element (115) that is inserted into a hole located at the lower end of the helical spring (200) to give it a unique position. The cells located at the end and corners of the base (100) of the module (15) have fastening means (135) for supporting a reinforcing element (130) consisting of an elongated structure such as a cable or wire. These fastening means (135) are formed by tunnels that cross the material of the outer walls of the modular base (100). In this way, the reinforcing element (130) runs through the tunnels through the entire periphery of the modular base (100) to strengthen its structure.

According to figures 3 and 4, the cells located on the base side (100) of the module (15) that is connected to another module (15) have, on the outside of said cells, joining means for receiving a modular joint element (150). Said joining means preferably consist of two tabs (120) which form a channel (121) in which a profile formed in the connecting element (150) slides. Additionally, at least one securing tab (122) prevents the connecting element (150) from sliding out of position. Said element of union (150) preferably consists of an insert of substantially rhomboidal shape. Figures 2IA and 21B show the preferred embodiment of the connecting element (150). In these figures it can be seen in detail that preferably the connecting element (150) has four profiles (151) at equidistant distances. The joining process between modules and at least one joining element (150) will be explained in detail later.

A first embodiment of the coil spring (200) is illustrated in Figures 5A to 5E, which has one or more helical turns (220) attached to a ring (210) at the lower end and to a connection structure (230) in the upper end, where the area circumscribed by the ring is larger than the area of the upper structure. In this embodiment, the coil spring (200) preferably has three turns (220), this number can vary. As shown in Figure 5E, the turns (220) preferably have an inverted "U" shaped cross section (225) that gives it additional structural strength regardless of the material from which they are made. However, said cross section can also take the oval, circular or square shape, as illustrated in Fig. 23. Additionally, said cross section can also take the form of "W", ^ΛΛ V ", ^Xλ H", ^Xλ Y " , ^Nλ I ", rhombus or double trapezoid, among others. It is important to emphasize the change in cross-section (225) that is robust at the lower end and becomes thinner as it goes up the propeller to reach the thinnest part at the upper end of the coil spring (200).

At the lower end of the helical spring (200), ring (210) has connection means (211) that preferably consist of three holes, located at equidistant distances at the intersection of the turns (220) with the ring (210); where they are inserted, the spring receivers (111) of the modular base (100) -. In this embodiment, the ring (210) preferably has ^"a circumference octagonal like cells (110) of the base (100) in its preferred embodiment .; However, the shape of the circumference of the ring (210) may vary depending on the shape of the cell to which it is attached.

At the upper end of the coil spring (200), the connection structure (230) receives at the tip of the upper end of the turns (220), which merge with the material of the connection structure (230) at equidistant points . In the first embodiment of the figures; 5A to 5E, the connection structure (230) of the helical spring consists of a second ring. Like the ring (210) of the present embodiment, the second ring preferably has an octagonal circumference. The inner edge (232) of the second ring allows to receive connection means of each cover. It should be noted that during assembly, the cover splices with the upper surface of the connection structure (230). :

Figures 6A to 6C illustrate a second embodiment of the coil spring (200). This second modality is similar to the first modality explained above, but it has a solid connection structure (240) that has the same shape as the cells (110) of the base (100) in its preferred mode. In addition, the connection structure (240) has receiving means that preferably consist of grooves (242) that allow the connection means of each cover to be received. It should be noted that during assembly, the cover splices with the upper surface of the connection structure (240). With regard to end subassemblies

(30) and skiing (40), these have at least one additional elastic element (250) as shown in] Figures 7A to 7C. Said additional elastic element (250) is preferably in the form of ^Xλ S ". Like the preferred embodiment of the helical spring (200), the additional elastic element (250) has an inverted" U "shaped cross section that gives it a additional structural strength regardless of the material it is made of. However, said cross section can also take the oval, circular or square shape, as illustrated in Fig. 23. Additionally, said cross section can also take the form of ^λλ W ", ^λλ V ", ^λλ H", ^λΛ Y ", ^Λλ I", rhombus or double trapezoid, among others.

The additional elastic element (250) has connection means (260) at its upper and lower ends. Said connection means (260) consist of at least one tongue that is coupled to the additional receiving means of the base (100) and additional receiving means of the end cover (330) and corner cover (360) Are the connection means (260) similar in shape and operation to the securing means (112) illustrated in Figures 22A and 22B. The elastic elements explained above can preferably be made of a plastic material. More preferably, said plastic material can be selected from Delrin® (registered trademark of EI du Pont de Nemours and Company for acetal resins), Hytrel® (registered trademark of E. I. du Pont de Nemours and

Company for thermoplastic elastomer resins ^' polyester base). Crastin® (registered trademark of E. du Pont de

Nemours and Company for polyester resins PBT), Rynite®

(registered trademark of E. du Pont de Nemours and Company for polyester PET resins), Zytel® (registered trademark of EI du Pont de Nemours and Company for nyion resins), Zytel® HTN (registered trademark of E.I. du Pont de Nemours and Company for high performance nylon resins), or other materials with similar characteristics. Figures 8A and 8B show the intermediate cover (300) that is used in the intermediate subassembly (20). Said intermediate cover (300) is connected to the connection structure of each helical spring (200). The cover is formed by a frame (310) that circumscribes a grid (315). In this mode, the frame (310) is octagonal in shape, as are the cells (110) of the base (10Ó) in its preferred mode. The grid (315) includes its center at least one section of material (320) • which circumscribes the connection structure of the coil springs (200). Preferably, the cover has four sections of material (320) that form a substantially circular area. In addition, the grid (315) projects from its lower surface, in the area circumscribed by the material sections (320), one or more connection means

(321) to engage the connection structure of the coil spring (200). As seen in Figure 8B, preferably the connection means (321) consist of four tabs that engage at the edge (232) or to the receiving means (242) located in the connection structure of the helical spring (200). Said connection means (321) are similar to the tongue of the securing means (112) illustrated in Figures 22A and 22B. Figure 11 shows a second modality of the intermediate cover (302) whose frame (312) has a circular shape and where its other elements are similar to those of the intermediate cover (300) in its first mode.

Figures 9A and 9B show the end cover (330) that is used in the end subassembly (30). The cover is formed by a frame (340) that circumscribes a grid (345). Like the grid (315) of the intermediate cover (300), the grid (345) includes at its center at least one section of material (350) that circumscribes the connection structure of the helical springs (200). Similarly, the cover has four sections of material (350) that form a substantially circular area. Also, the grid (345) projects from its lower surface, in the area circumscribed by the section of material (350), one or more connection means (351) to engage the connection structure of the helical spring (200). Preferably, said connection means (351) consist of four tabs that engage at the edge (232) or to the receiving means

(242) located in the connection structure of the coil spring (200). Said connection means (351) are similar to the tongue of the securing means (112) illustrated in Figures 22A and 22B. Unlike the intermediate cover (300), the end cover (330) has additional receiving means (352) that preferably consist of three grilles adjacent to the frame of the cover and whose interior is slightly thickened by material to be able to receive the connection means (260) of one or more additional elastic elements (250). In the preferred embodiment illustrated in Figure 1, the end subassemblies (30) have only one or two additional elastic elements (250). In this case, any of the three additional receiving means (352) that are located on three sides of the end cover (330) can be used.

Additionally, the end cover (330) has on one of its sides fastening means (355) to support a reinforcing element (390) of the periphery of the modular suspension system (10). Said fastening means (355) consist of two or more fasteners (356) attached to the outer wall of the frame and whose tip (357) is curved. At least one fastener (356) is in opposite direction to one or more fasteners (356). In the end cover (330), the fastening means (355) are located on the same outer wall of the frame (340).

Figures 1OA and 1OB show the corner cover (360) that is used in the corner subassembly (40). The cover is formed by a frame (370) that circumscribes a grid (375). Like the grilles (315) and (345), the grille (375) includes at its center at least one section of material (380) that circumscribes the connection structure of the helical springs (200). Similarly> the cover has four sections of material (380) that form a substantially circular area. Also, the grid (375) projects from its lower surface, in the ^' area circumscribed by the material section (380), one or more connection means (381) to engage the connection structure of the helical spring (200) . Preferably, said connection means (381) consist of four tabs that engage at the edge (232) or to the receiving means (242) located in the connection structure of the helical spring (200). Said connection means (381); they are similar to the tongue of the securing means (112) illustrated in Figures 22A and 22B. ;

Like the end cover (330), the corner cover (360) has additional receiving means (382) which preferably consist of four grilles adjacent to the frame of the cover and whose interior is slightly thickened by material to be able to receive the connection means (260) of one or more elastic elements additional (250). In the preferred embodiment illustrated in Figure 1, the corner subassembly (40) has only two additional elastic elements (250). In this case, any of the four additional reception means (382) can be used located on four sides of the cover.

Additionally, the corner cover (360) has fastening means (385) to support a reinforcing element (390) of the periphery of the modular suspension system (10). Said fastening means (385) are equal to the fastening means (355) of the end cover (360). However, in the corner cover (360), the fastening means (385) are located on two outer walls of the frame (370) located 90 ° from each other. The construction of the modular suspension system

(10) of the present invention will be explained by analyzing how to assemble each of the sub-assemblies.

First, each ring (210) of the helical spring (200) is positioned on each cell (110). As explained above, the spring receivers (111) are substantially cylindrical structures that are introduced into the connection means (211) of the helical spring (200). Figure 15 shows the intermediate sub-assembly (20) where the ring (210) placed on the cell (110) is observed. This figure shows how the securing means (112) are positioned on the upper surface of the ring (210). In this way, the spring receivers (111) (not illustrated in this figure) and the means of securing (112) allows each helical spring (200) to be positioned in place.

However, the coupling between the helical spring (200) in its first embodiment and the intermediate cover (300) is shown in Figure 12A, where the upper surface of the connection structure (230) is spliced against the inner surface of the intermediate cover (300) in the area delimited by the material section (320) and the connection means (321) of said cover are secured to the edge (232) thus securing the helical spring (200). It should be noted that in the embodiment illustrated in Figure 12A, the intermediate cover (300) is free to rotate with respect to the helical spring (200) because the connection means (321) allow the rotation of the second ring of the helical spring ( 200) . The foregoing is of particular importance since there is a problem that when the coil spring (200) is compressed, it will attempt to rotate on its vertical axis. The solution proposed in this modality allows to solve this problem. ^: Similarly, Figure 12B illustrates the intermediate cover (300) connected to the coil spring (200) in its second mode. Basically, the coupling form is the same with the difference that the connection means (321) of the intermediate cover (300) are introduced through the slots (242) of the connection structure (240) - of the helical spring (200) . It should be noted that in this case, the intermediate cover (300) cannot rotate with respect to the helical spring (200). Figure 16 shows the end subassembly (30) which is similar to the intermediate subassembly (20): However, the end subassembly (30) carries two additional elastic elements (250). In figure 16 only one is shown. The additional elastic element (250) is attached, at its lower end, through the connection means (260) (not illustrated in this figure) to the receiving element (113) of the cell (110). As mentioned above, in the preferred embodiment, only the cells located on the periphery of the system have the additional elastic element receiving elements 113.

Figure 13 shows the coupling between the helical spring (200) in its first mode, and the end cover (330), wherein the upper surface of the connection structure (230) is spliced against the inner surface of the cover of end (330) in the ^' area delimited by the material section (350) and the connection means (351) of said cover are secured to the edge (232) thus securing the helical spring (200). This figure also shows how two additional elastic elements (250) are coupled in the additional receiving means (352) through the connecting means (260) of said elastic elements.

Similarly, Figure 17 shows the corner subassembly (40). It should be noted that in the preferred embodiment of the modular suspension system (10) in its entirety, it can only have four sub-assembled subassemblies. (40). This figure shows that said subassembly has two additional elastic elements (250) that are adapted in the same manner in which the additional elastic elements (250) are adapted in the end subassembly (30).

Similarly, the coupling between the helical spring (200) in its first mode and the corner cover (360) is shown in Figure 14, where the upper surface of the connection structure (230) is spliced against the inner surface of the end cover (360) in the area delimited by the material section (380) and the connection means (381) of said cover are secured to the edge (232) thus securing the helical spring (200). This figure also shows how two additional elastic elements (250) are coupled in the additional receiving means (382) through the connecting means (260) of said elastic elements.

As seen in Figure 18, all the elastic elements of the module (15) of the modular suspension system (10) are positioned in the same direction. The above is to prevent the elastic elements from making contact with each other during the use of the system.

The suspension system of the present invention is modular because it can be composed of one or more modules (15) as described. The way in which the modules (15) are joined is shown in Figure 19, where two modules (15) joined by the outer walls of one of its sides are illustrated. Said outer walls form intracell spaces located along the joining side of the modules (15). Figure 20 shows an approach of Figure 19, in where it is observed how the profile (151) of the modular joint element (150) is inserted into the channel (121) formed in said intracell spaces. In addition, at least one binding tab

(122) located on at least one of the outer walls of the cells prevents the connecting element (150) from sliding out of place. The modularity of the system of the present invention allows suspension systems to be formed according to the manufacturing requirements of the padded product to be manufactured. Finally, once the modular suspension system of the present invention is assembled, the reinforcing element (390) is attached, which consists of an elongated structure such as a cable or wire, which runs on the curved tips of the fastening means ( 355) and (385) of the end covers (330) and corner (360) respectively. It is important to emphasize that this element allows greater stability in the entire periphery of the system.

Based on the foregoing disclosure, certain embodiments and details have been described in order to illustrate the present invention, and it will be apparent to those skilled in the art that variations and modifications can be made without departing from the scope of the present invention.
