Description

Improved elastic pad structure

This invention relates to an improved structure of an elastic cushion; in particular, it refers to a new type of structure that uses thermoplastic elastic materials and/or gel and latex composite materials to provide better support and heat dissipation functions.

It is a known art to use a sponge layer made of fabric or foam material to cover an elastic object or a spring group to provide an elastic mattress for people to sit or lie on (e.g., sofa, bed, chair, etc.); for example, Patent No. 98207868 "Structure of Spring Mattress", Patent No. 95206694 "Spring Mattress", and Patent No. 93208614 "Structural Improvement of Spring Mattress" provide typical embodiments.

This type of elastic pad usually has appropriate softness and hardness, and conforms to the principle of ergonomics, so as to support the person to get comfort. Basically, this type of elastic pad includes a fabric layer or a covering layer covering a foam material layer, or provides a rigid frame, and multiple spring groups are arranged on the rigid frame; the rigid frame and the spring group are covered with a sponge layer made of foam material and a fabric layer or a covering layer to form an elastic pad assembly; providing the person with comfort when sitting or lying.

One of the issues in the manufacturing and structural design of this type of elastic pad product is that the conventional technology has long followed the old structural type (e.g., a fabric layer wrapped with a foam material layer and/or a rigid frame, etc.), which has gradually lost its appeal and market competitiveness. Moreover, during high-frequency and/or long-term use by personnel, the old structural type of foam layer and/or rigid frame not only has poor air permeability, causing the personnel to feel warm and uncomfortable during use; and the conventional structural type usually cannot provide better support, but is prone to depression in the load-bearing area, which in turn reduces the service life of the elastic pad assembly, which is not what we expect.

Typically, these references show design techniques related to elastic pads or their analogs and related structural combinations. If the organizational structure of the elastic pad is redesigned and considered to be different from that of the user, its usage pattern can be changed and different from the old method; in essence, its application range will be increased. For example, in terms of the organizational structure of the elastic pad, if its structural design is considered to provide better support (for the human body) under the conditions of being in line with the load (or ergonomics); or further improve the situation that the structure is prone to produce warmth (or poor breathability) during use. These topics are not specifically taught or disclosed in the above references.

Therefore, the main purpose of this invention is to provide an improved structure of elastic pad, which provides better support and heat dissipation. It includes a combination of a fabric layer, a carrier layer and a base layer (and/or a sub-base layer) disposed between the fabric layer and the carrier layer. The base layer (and/or the sub-base layer) is a thermoplastic elastic material (Thermoplastic elastomer, elastoplastics; abbreviated as TPE) and/or a combination (or mixed) material of gel and latex, forming a geometric outline structure (or plate structure, block structure), and establishing a support (human body) function. In addition, the base layer (and/or the sub-base layer) is provided with a plurality of airflow channels (matching the material properties of the base layer) to provide a temperature or heat dissipation mechanism suitable for use by personnel, thereby improving the use conditions of the known structure with poor breathability and thermal discomfort.

According to the improved elastic cushion structure of the present invention, the fabric layer and the carrier layer have an upper surface and a lower surface respectively, and the base layer (and/or the auxiliary base layer) has a first surface facing the lower surface of the fabric layer and a second surface facing the upper surface of the carrier layer. Or the first surface of the base layer (and/or the auxiliary base layer) contacts (or connects) the lower surface of the fabric layer, and the second surface of the base layer (and/or the auxiliary base layer) contacts (or connects) the upper surface of the carrier layer. In addition, the fabric layer can be formed into a shape covering the first surface of the base layer (and/or the auxiliary base layer) and the lower surface of the carrier layer to form a (chair cushion) assembly.

According to the improved elastic mattress structure of the present invention, an elastic mechanism is arranged between the second surface of the base layer (and/or the auxiliary base layer) and the upper surface of the carrier layer; and the fabric layer can be formed into a shape covering the first surface of the base layer (and/or the auxiliary base layer) and the lower surface of the carrier layer to form a (mattress) assembly.

According to the improved structure of the elastic pad of the invention, a secondary base layer is arranged in the assembly (or between the first surface of the base layer and the lower surface of the fabric layer or between the second surface of the base layer and the upper surface of the carrier layer). The base layer is made of thermoplastic elastic material, and the secondary base layer is made of a combination of gel and latex to form a structure with a geometric outline.

Please refer to Figures 1 and 2. The elastic pad improved structure of the invention includes a combination of a fabric layer, a carrier layer, and a base layer disposed between the fabric layer and the carrier layer; the fabric layer, the carrier layer, and the base layer are respectively represented by reference numbers 10, 20, and 30. The fabric layer 10 can be made of cloth, leather, or similar materials; the carrier layer 20 can be made of cotton, wood, or similar materials to form a plate-like structure.

The terms upper, above, lower, below, outside, inside, etc. mentioned in the following descriptions are based on the directions shown in the figure as reference directions.

The figure also depicts that the fabric layer 10 and the carrier layer 20 have upper surfaces 11, 21 and lower surfaces 12, 22 respectively, and the base layer 30 has a first surface 31 facing the lower surface 12 of the fabric layer and a second surface 32 facing the upper surface 21 of the carrier layer. Or the first surface 31 of the base layer contacts (or connects) the lower surface 12 of the fabric layer 10, and the second surface 32 of the base layer contacts (or connects) the upper surface 21 of the carrier layer 20. In addition, the fabric layer 10 can be formed into a shape that covers the first surface 31 of the base layer and/or the lower surface 22 of the carrier layer to form a (seat cushion) assembly 100.

In the embodiment adopted, the base layer 30 is a thermoplastic elastic material (TPE) and/or a combination (or mixed) of gel and latex to form a geometric structure (or plate structure, block structure) and to establish a support (for the human body). In addition, the base layer 30 is provided with a plurality of airflow channels 33 (matching the material properties of the base layer 30) to provide a temperature or heat dissipation (or cooling) mechanism suitable for use by personnel, and to improve the use conditions of poor breathability of the known structure, thermal discomfort, etc.

Figures 1 and 2 reveal that the base layer 30 is made of thermoplastic elastic material to form a (high) elastic structure, which has the characteristics of environmental protection, non-toxicity, high strength, high resilience, soft touch, fatigue resistance and temperature resistance. In addition, the airflow channel 33 of the base layer 30 penetrates the first surface 31 and the second surface 32, so that the airflow channel 33 can establish a mechanism for airflow movement or circulation to achieve the effects of ventilation, heat dissipation or temperature reduction. The airflow channel 33 can form a geometric profile (or cross-section); for example, a triangle, square, hexagon (or honeycomb), circle... and other structural types.

The figure also shows that an additional layer 40 is provided between the base layer 30 (or the second surface 32 of the base layer) and the carrier layer 20 (or the upper surface 21 of the carrier layer); the additional layer 40 can be made of cotton, foam, rags and other materials to form a (plate-shaped or block-shaped) structure to assist in supporting the base layer 30 and/or increase the softness of the assembly 100.

2 specifically depicts a configuration in which the second surface 32 of the base layer 30 is disposed (or connected) on a secondary fabric layer 35. Therefore, the additional layer 40 is disposed between the secondary fabric layer 35 and the carrier layer 20 (or the carrier layer upper surface 21).

Therefore, FIG. 2 discloses that the lower surface 12 of the fabric layer 10 sequentially (from top to bottom in the figure) constitutes the configuration of the base layer 30 (and/or the secondary fabric layer 35), the additional layer 40, the carrier layer 20 and/or the fabric layer 10.

Referring to Figs. 3 and 4, an elastic mechanism 70 is disposed between the second surface 32 of the base layer 30 and the upper surface 21 of the carrier layer 20; and the fabric layer 10 can be formed into a shape covering the first surface 31 of the base layer and the lower surface 22 of the carrier layer to form a (mattress) assembly 100. The elastic mechanism 70 is a combination of a plurality of elastic devices 71 (or spring tubes) and a frame 72; and the carrier layer 20 can be used to support the elastic mechanism 70, the additional layer 40, the base layer 30 and other parts.

The figure also depicts a filling layer 60 disposed between the lower surface 12 of the fabric layer 10 and the first surface 31 of the base layer 30. The filling layer 60 can be made of materials such as polyester fiber, cotton, etc., and fills the area between the fabric layer 10 and the base layer 30 to increase the comfort of a person lying on the fabric layer 10.

Therefore, Figures 3 and 4 reveal that the lower surface 12 of the fabric layer 10 sequentially (from top to bottom in the figure) constitutes the filling layer 60, the base layer 30 (and/or the secondary fabric layer 35), the additional layer 40, the elastic mechanism 70, the carrier layer 20 and/or the configuration of the fabric layer 10.

Please refer to FIG. 5 , which shows a feasible embodiment. The “base layer” of the embodiment is defined as a sub-base layer 50; the sub-base layer 50 uses a combination of gel (particles) and latex materials to form a structure with a geometric outline (or a plate-like structure, a block-like structure), and establishes a support (for the human body). In addition, the sub-base layer 50 also has a first surface 51 facing the lower surface 12 of the fabric layer and a second surface 52 facing the upper surface 21 of the carrier layer. The sub-base layer 50 is provided with a plurality of airflow channels 53 (matching the material properties of the sub-base layer 50) to provide a temperature or heat dissipation (or cooling) mechanism suitable for use by personnel; to improve the use of the known structure with poor air permeability, thermal discomfort, etc.

In the embodiment, the air flow channel 53 of the secondary base layer 50 penetrates the first surface 51 and the second surface 52, so that the air flow channel 53 establishes a mechanism for air flow movement or circulation, thereby achieving the functions of ventilation, heat dissipation or temperature reduction. The air flow channel 53 can form a geometric outline (or cross section); for example, a triangular, square, hexagonal (or honeycomb), circular, etc. structural form.

Therefore, FIG. 5 reveals that the lower surface 12 of the fabric layer 10 sequentially (from top to bottom in the figure) constitutes the filling layer 60 , the sub-base layer 50 , the additional layer 40 , the elastic structure 70 , the carrier layer 20 and/or the configuration of the fabric layer 10 .

Please refer to FIG. 6 , which depicts a modified embodiment; a base layer 30 and a sub-base layer 50 are disposed between the fabric layer 10 and the carrier layer 20 to increase the support function (and/or heat dissipation effect) of the assembly 100. The base layer 30 is made of a thermoplastic elastic material to form an elastic structure, and the sub-base layer 50 is made of a gel (granules) and latex composite material to form a structure.

Therefore, Figure 6 reveals that the lower surface 12 of the fabric layer 10 is sequentially (from top to bottom in the figure) composed of a filling layer 60, a base layer 30 (or the first surface 31 of the base layer contacts the filling layer 60), a sub-base layer 50 (or the first surface 51 of the sub-base layer contacts the second surface 32 of the base layer), an elastic structure 70, a carrier layer 20 and/or a configuration of the fabric layer 10.

Please refer to FIG. 7 , which depicts a derivative embodiment; a base layer 30 and a sub-base layer 50 are disposed between the fabric layer 10 and the carrier layer 20 to increase the support function (and/or heat dissipation effect) of the assembly 100. The base layer 30 is made of a thermoplastic elastic material to form an elastic structure, and the sub-base layer 50 is made of a gel (granules) and latex composite material to form a structure.

Therefore, Figure 7 reveals that the lower surface 12 of the fabric layer 10 is sequentially (from top to bottom in the figure) composed of a filling layer 60, a sub-base layer 50 (or the first surface 51 of the sub-base layer contacts the filling layer 60), a base layer 30 (or the first surface 31 of the base layer contacts the second surface 52 of the sub-base layer), an elastic structure 70, a carrier layer 20 and/or a configuration of the fabric layer 10.

Typically, this improved elastic pad structure has the following advantages over the old method while being ergonomic and providing load-bearing conditions:

1. The structural type of the assembly 100 has been redesigned and considered to be different from the user and to change its use, operation type and application scope, which is different from the old method. For example, a base layer 30 and/or a sub-base layer 50 are arranged between the fabric layer 10 and the carrier layer 20, and the base layer 30 and/or the sub-base layer 50 use thermoplastic elastic material (abbreviated as TPE) and/or gel, latex combination (or mixed) material to form a structure with a geometric outline (or a plate-like structure, a block-like structure); the base layer 30 and/or the sub-base layer 50 are combined with an additional layer 40 or an elastic mechanism 70 and other parts. It has significantly improved the situation where knowledge and skills have long been sticking to the old structural forms and shapes, gradually losing their appeal and market competitiveness.

2. In particular, the tissue structure of the assembly 100 or the base layer 30 (and/or the sub-base layer 50) can provide better support (for the human body), which significantly improves the situation that the known structure is prone to depression in the load-bearing area and reduces the service life; and the situation that the known structure is prone to produce warmth (or poor breathability) during use and other discomforts are further improved.

Therefore, this invention provides an effective improved structure of elastic pad, whose spatial form is different from the known one and has advantages that cannot be compared with the old method. It shows considerable progress and fully meets the requirements of a new patent.
