Description

Seat cushion and seat back combination structure

This creation is about the combination of the seat cushion and the seat back of the seat.

Figures 1 and 2 depict a conventional seat cushion assembly structure including a seat body 1 based on a single piece of wood, an elastic pad body 2 placed on the seat body, and a cover for the elastic pad body 2 and the seat body 1 of fabric 3. After the edge of the fabric 3 covers the elastic pad 2 and the circumferential surface of the base 1, the bottom surface of the base 1 is folded, and the edge of the fabric is fixed to the bottom surface of the base by a plurality of fixing nails 4. In order to maintain the gas permeability, the seat body 1 is provided with a plurality of holes 5.

The disadvantages of the above-mentioned conventional seat cushion combination structure are as follows: 1. The seat cushion needs to be taken from the whole piece of wood, which may increase the problem of excessively felling trees. Second, when using wood materials, it is necessary to cooperate with pre-processing operations such as deworming, surface treatment, drilling, etc., to increase process time and steps, and to handle troubles. Third, the use of chemical insecticides and surface treatment agents involved in sewage treatment problems, fear of increasing environmental burden and environmental protection issues. 4. If fabrics and elastic cushions need to be cleaned or replaced, many fixing nails must be removed with professional tools. The process is very time-consuming and labor-intensive; and the return-to-return combination also requires professional tools and people, and the average person can operate it by himself. 5. This type of seat is discarded when the fabric is dirty or the elasticity of the elastic cushion is insufficient, resulting in waste. 6. When the whole chair is discarded, it is difficult for the recycling plant to disassemble it for recycling.

In order to solve the above problems, the present invention proposes a seat cushion combination structure.

The present invention features a seat cushion and a seat back combination structure, comprising: a body, which is integrally formed of plastic and has a strong supporting surface; the seat body is provided with at least one ring groove along the periphery thereof, and the groove of the ring groove faces upward The depth of the ring groove is greater than the width, and one of the groove sides of the ring groove is partially provided with a tool socket; an elastic support pad is disposed on the support surface of the seat body; at least one supporting fabric, the peripheral edge of the supporting fabric Embinging a resilient backing ring and fixing it by a plurality of fixing elements, thereby forming a positioning edge of the supporting fabric; the supporting fabric covering the elastic supporting pad, the supporting fabric is filled with the positioning edge tightly In the ring groove, the supporting fabric is in a tension state.

Preferably, the support surface is formed with a plurality of holes for increasing gas permeability and promoting air convection.

Preferably, the supporting surface is formed at the back to form a staggered rib for increasing the structural strength of the seat; a fixed hole column is formed at a plurality of staggered portions of the rib, and the seat and a seat are assembled by the component One foot assembly.

Preferably, the annular groove has a ratio of depth to width of at least 2:1.

Preferably, the ring groove comprises an inner ring groove and an outer ring groove.

Preferably, the area of the elastic support pad disposed on the support surface of the base body covers the inner ring groove, and the positioning edge of the support fabric is tightly filled in the outer ring groove.

Preferably, the support fabric comprises a first support fabric and a second support fabric.

Preferably, the first supporting fabric is a mesh fabric, and the second supporting fabric is a fabric having elasticity, supportability and air permeability; the first supporting fabric covers the elastic supporting mat, and the first supporting branch The gusset fabric is filled with the locating edge liner in the inner ring groove; the second support fabric covers the first support fabric and the elastic support pad, and the second support fabric is filled with the locating edge lining The outer ring groove.

The effect of this creation:

The seat of the seat cushion is integrally formed of a plastic material, which overcomes the defects of the first, second and third items described in the prior art, conforms to the environmental protection concept, and is light in weight.

The support fabric and the elastic support pad can be replaced without professional tools, without the need of professionals and technology, the user can operate the disassembly and combination, extend the service life of the seat, and overcome the fourth and fifth items mentioned in the prior art. Missing.

Based on the convenience of the above-mentioned exchange, it is convenient for the recycling plant to disassemble and recycle, and overcome the lack of the sixth item mentioned in the prior art.

For the convenience of the description, the central idea expressed in the column of the above novel content is expressed by a specific embodiment. Various items in the embodiments are depicted in terms of ratios, dimensions, amounts of deformation, or displacements that are suitable for illustration, and are not drawn to the proportions of actual elements, as set forth above.

As shown in FIG. 3, the seat cushion combination of the present invention includes a body 10, an elastic support pad 20 disposed on the base body 10, and at least one covering the elastic support pad 20 and having a periphery fixed to the seat body. 10 support fabric 30.

As shown in Figures 4 and 5, the body 10 is integrally formed with a solid support surface 11 which is formed with a plurality of holes 12 for increasing the gas permeability and promoting air convection; the support surface 11 is formed on the back to increase The staggered ribs 13 of the structural strength of the base 10; a fixed hole post 14 is formed at each of the plurality of staggered portions of the ribs 13, and the base 10 and the seat of the seat 50 are formed by a plurality of combined components (not shown). Assembly 53 (as shown in Figure 3). The seat body 10 is provided with a ring groove 16 along its circumference. The groove of the ring groove 16 faces upward, and the groove type is characterized by a depth greater than a width. Preferably, the ratio of the depth to the width is at least 2:1, and A tool socket 17 is partially provided on one of the side of the groove. In the present embodiment, the ring groove 16 includes an inner ring groove 161 and an outer ring groove 162.

As shown in FIG. 6, the support fabric 30 includes a backing ring 31, and the periphery of the support fabric 30 is wrapped around the backing ring 31 and fixed by the fixing member 32, thereby forming a positioning edge 33 of the supporting fabric 30. . The fixing member 32 is a suture in which the two are sewn together. The backing ring 31 is a ring made of a material having elastic strain, stiffness, and support (for example, rubber); the supporting fabric 30 may be a mesh or a cloth having elasticity, supportability, and air permeability. In the present creative embodiment, The support fabric 30 includes a first support fabric 301 and a second support fabric 302.
