Description

The present invention belongs to the technical field of upholstered furniture, and more particularly to an upholstered furniture core and an upholstered furniture using the upholstered furniture core.

Traditional upholstered furniture mainly refers to furniture whose main body is sponge and fabric. It is mainly divided into bed type and sofa type. The most common bed products are mattresses and pillows, and the most common sofa products are zabuton cushions, lumbar cushions, and armrests.

Traditional upholstered furniture usually uses soft cushioning, sponge, or natural palm fiber as the main material and is glued together using adhesives or shaped by other connecting methods. . Sponge, natural coconut fiber and latex are the most commonly used core materials for upholstered furniture, especially as people's comfort requirements continue to improve. Cores made from these materials have very low open porosity and can be considered solid cores. Solid cores have the following drawbacks. First, when used, the area where the solid core attaches to the surface of the human body is very large, and the sponge, natural coconut fiber, and latex materials have very good absorbency and heat retention, so the surface of the human body and The temperature and humidity of the air in the area between the solid core body is high, the air cannot circulate smoothly, and it is not comfortable for the human body. Next, since the curvature of the human body curve is complex and there are large individual differences, the external force acting on the surface of the solid core in the area of protruding radiance is greater than the external force acting on the surface of the solid core in other areas. The unbalanced force receiving causes an obvious depression in the corresponding area on the surface of the lid core body, and since the solid core body is a continuous and flat whole, this causes a non-pressure depression in the surrounding area, and the surrounding become unsupportable in the area of

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention is further described in detail with reference to the drawings and examples below.

In the description of the present invention, terms such as "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside", etc. For convenience of explanation, it does not imply that the device or element has a particular orientation, is configured and operated in a particular orientation, and should not be construed as limiting the invention. Further, the terms "first" and "second" are for descriptive purposes only and are not meant to indicate relative importance.

The solid core body used in conventional upholstered furniture has a large contact area with the human body surface, which is not comfortable for the human body, and is easy to collapse, especially in the peripheral area, where non-pressure type depression occurs. brings about the problem of no support, specially designing the core body 1 of upholstered furniture with novelty. Such an upholstered furniture core 1 can be applied in bedding, as a mattress or part of a mattress, or as a pillow or part of a pillow. It can also be applied to sofa or seat products as a cushion or part of a cushion, as a back pad or part of a back pad, or as an armrest or part of an armrest. As shown in FIGS. 1-4, a core body 1 of such upholstered furniture comprises an elastic base 10 on which a plurality of elastic grid units 11 are formed. Each elastic grid unit 11 is surrounded by elastic walls 12 . Two adjacent elastic grid units 11 have a common edge to form a line connection, or have a common side wall to form a plane connection. Specifically, any two adjacent elastic grid units 11 are installed symmetrically, and the elastic walls 12 surrounding the two adjacent elastic grid units 11 are connected to each other on the axis of symmetry, i.e. the common side Or the common sidewall lies on the axis of symmetry. As shown in the examples of FIGS. 2 and 3, here there is a common sidewall between adjacent elastic grid units 11-1 and 11-2, the common sidewall being the axis of symmetry 15-1. located above and form a surface connection between the two elastic grid units 11 . There is a common side between adjacent elastic grid units 11-1 and 11, and the common side is located on the axis of symmetry 15-2. In such a connection method of arranging the elastic grid units 11, the elastic base 10 has a certain degree of flexibility and a good supporting effect, and is comfortable to use.

Specifically, as shown in FIGS. 1-4, each elastic grid unit 11 has a first end face 13 and a second end face 24 formed at both ends of the elastic wall 12 . Here, the first end surfaces 13 of the plurality of elastic grid units 11 jointly form the force-bearing surface P1 of the core body, the second end surfaces 24 of the plurality of elastic grid units 11 are coplanar, and the core body Jointly form a connection surface P2. Here, the force-receiving surface P1 of the core body may be coplanar, or may be designed to have an ergonomically designed curve. For example, when the core body is applied to a back pad, It may be designed to protrude into the corresponding waist region. Since the elastic grid unit 11 has a hollow structure and is surrounded by the elastic wall 12, each elastic grid unit 11 has relatively good tensile strength, and the critical elongation distance is more than 7 times its original length. can reach. Two adjacent elastic grid units 11 form a line connection or surface connection only on the axis of symmetry, so that the elastic base 10 as a whole can tolerate a larger amount of deformation under the action of external force, and irreversible deformation is less likely to occur. In addition, due to the action of non-uniform external force, the interaction force between two adjacent elastic grid units 11 is low, and a substantially independent supporting form can be maintained, and each elastic grid unit 11 is an independent It can be a bearing force unit, so that when an area is greatly collapsed under the action of external force, the adjacent elastic grid unit 11 will not experience obvious collapse, and the adjacent area still provides sufficient bearing force. do. FIG. 5 is a graph showing the relationship between pressure and core height variation, where Y1 represents a conventional solid core and Y2 represents a core provided by this embodiment. The vertical axis represents the pressure, and the horizontal axis represents the amount of change in height of the core. In a conventional solid core, as the pressure increases, the amount of change in the height of the core increases, approaching a linear relationship between the two. In the core provided by this embodiment, as the pressure increases, the height change of the core gradually enters the platform section. The external force can be evenly distributed by the plurality of elastic grid units 11 without changing, maintaining a sufficient supporting force without generating an excessive reaction force. For example, the hip curve of the human body is convex, and when the height variation of the core body enters the platform section, the core body in contact with the buttocks can collapse with a small amplitude to meet the human body curve, and at the same time there is an excessive reaction. It does not generate force and does not cause discomfort to the body.

A core connection surface P2, which is the second end surface of the plurality of elastic grid units 11 on the same plane, is mainly used for connection with other auxiliary materials. The core connection surfaces P2 may be connected by forms of adhesives, adhesive layers and other materials, or may be connected using physical connection forms such as stitching, rivets and other material connections.

In order to increase the structural strength of the elastic base, especially the elastic grid unit 11, an auxiliary base 21 is preferably further formed. The auxiliary base 21 has a flat and complete surface connected to the core connecting surface P2.

In this embodiment, the elastic wall 12 is preferably made of a thermoplastic elastomer material, which provides a balance between flexibility, softness and support properties so that the core is more comfortable. . As can be appreciated by those skilled in the art, the resilient wall 12 may be of other types made of polymeric material having a certain elasticity. A plurality of elastomeric units can be integrally molded by a thermoplastic process and can be integrally molded in the manner of 3D printing. Since a direct bond between the plastic elastomer material and the partially melted adhesive, water-soluble adhesive is not possible, the auxiliary substrate 21 compatible with the plastic elastomer material is especially made of knitted, woven or non-woven fabrics. preferable. During processing, the elastic base body made of thermoplastic elastomer material and the matching auxiliary base body 21 can be connected by hot stamping or a one-piece injection molding process.

The elastic substrate with the auxiliary substrate 21 manufactured by hot stamping or integral injection molding process can be divided into a plurality of standard size unit modules. Also, unit modules of standard dimensions can be manufactured by hot stamping or integral injection molding processes, and the required working dimensions are reached by the joining method, where the dimensions of the length and width of the elastic substrate are not further limited. .

As an example in which the core is applied to a mattress product, the force-receiving surface of the elastic core and the connecting surface P2 of the core are both designed to be on the same plane when applied to a mattress product. preferably. Alternative constructions for the optional elastic grid unit 11 are described with reference to Figures 6-14. The elastic grid unit 11 includes a hollow area 14 formed inside the elastic wall 12 . The area of each hollow region 14 is in the range of 1 cm ² to 16 cm ² . If the area of the hollow region 14 is too large, the load bearing capacity is likely to be lost. If it does not have an elastic support and is subjected to the action of an external force, lamination may occur and the effect of elastic support may be lost. Overall, the total area of the plurality of hollow regions 14 is 70% to 90% of the area of the elastic substrate, achieving a high level of porosity and excellent air permeability throughout the core.

The wall thickness of the elastic wall 12 is 1 mm to 10 mm. If the wall thickness is too small, the supporting force of the elastic wall 12 is insufficient. A wall thickness in this interval can meet the requirements of the machining process. The height of the elastic wall 12 is between 1 cm and 15 cm, which is too low to provide sufficient subsidence depth. Especially when applied to a mattress, the height of the elastic wall 12 is within this interval, and the gravity of the human body can be well distributed. The weight of the entire mattress can be controlled to a lower level in terms of weight.

As shown in FIGS. 6 and 7, the cross-section of the elastic grid unit 11 may be designed as a regular hexagon (shown in FIG. 16), and the whole is distributed in a crystalline form. As shown in Figures 8 and 9, the cross section of the elastic grid unit 11 may be designed triangular (shown in Figure 17). It should be particularly mentioned that, as shown in FIGS. 10 and 11, the triangularly designed elastic grid units 11 may also be arranged in rows (as shown in FIG. 18), so that multiple rows elastic grid unit 11 can be further assembled to achieve better strength along the longitudinal direction and meet the specific needs of different mattress products. As shown in FIGS. 12-14, the cross-section of the elastic grid unit 11 may be designed circular (shown in FIG. 19), and the edges of the elastic substrate are provided with protective walls as shown in FIG. Often, as shown in FIG. 12, protective walls are not installed on the sides of the elastic base. Furthermore, the cross-section of the elastic grid unit 11 may be designed as an oval or other shaped regular polygon.

In many applications, the elastic substrate needs to have increased supporting strength. Specifically, as shown in FIGS. 15 to 17, a supporting substrate 30 is further installed on the core. Support substrate 30 is supported by sponge, latex, spun fibers, hoses or springs. The support base 30 may be installed in one, the support base 30 may be connected to the core connection surface P2, and the connection between the support base and the core connection surface P2 may be by adhesion, stitching or riveting. A physical connection scheme may also be used. The support base may be connected to an auxiliary base 21, as shown in FIG. According to the strength requirements of the product, more than one support substrate (shown at 30-1 and 30-2 in FIG. 17) can be designed, and multiple support substrates are arranged in a stack, and the top layer is A supporting base 30 - 1 located is connected to the auxiliary base 21 . The connection between the support base 30-1 and the auxiliary base 21 may be made by using a physical connection method such as adhesion, stitching, or rivets.

Furthermore, a plurality of elastic substrates may be installed on one core, and the plurality of elastic substrates are evenly distributed. The plurality of elastic bases are connected by a first support base, and the first support base is installed around the elastic bases. The first supporting substrate surface is flush with the core connection surface P2. The first supporting base and the elastic base in the connected state may be connected to the auxiliary base 21 or may be connected to the second supporting base. Connections can similarly use physical connection methods such as gluing, stitching or riveting. Both the first supporting substrate and the second supporting substrate may be composed of sponge, latex, spun fibers, hoses or springs.
