Description

Technical Field

[0001] The utility model relates to the field of chairs, in particular to a novel chair seat. Background Art

[0002] Traditional chair seats on the market consist of a support plate, a cushion, and a cloth covering the cushion. The commonly used method for fixing the support plate, the cloth covering, and the cushion is to stack the support plate, the cushion, and the cloth covering together from top to bottom in this order, and then turn the cloth covering and the cushion over the back of the support plate. A circle of nails is then used to fix the cloth covering, the cushion, and the support plate. This fixing method requires a circle of nails to be driven into the support plate, which is not only time-consuming but also prone to waste of nails.

[0003] In addition, when the support plate and cushion are of special shape, the processing difficulty will be further increased; the irregular shape of the support plate and cushion will make it difficult to control the width of the cover cloth and cushion flange, and the flange width will be longer or shorter at different positions of the support plate; at the same time, the uneven width of the cover cloth and cushion flange also increases the difficulty of arranging the position of the nail gun, which can easily cause the nail gun to deviate and increase the difficulty of installation. Summary of the Invention

[0004] In order to solve the above problems, the purpose of the present invention is to provide a new type of chair seat, in which the seat cushion is stacked on a support plate, and after the opposite sides of the seat cushion are flanged, the seat cushion is positioned on the support plate by means of nails, and then fixed by tightening the drawstring, so that the seat cushion is tightly attached to the inner side of the back side of the support plate. While greatly reducing the amount of nails used, it also ensures the positioning and fixation of the seat cushion and the support plate, reduces the difficulty of installation, and improves the production efficiency of the chair seat.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] A novel chair seat comprises a support plate and a seat cushion fixed on the front of the support plate; the support plate is a supporting member of the chair seat; the seat cushion comprises a cover cloth and a soft pad sequentially arranged on the front of the support plate;

[0007] A circle of drawstring is connected to the outer edge of the cover cloth; the two ends of the drawstring are exposed at the edge of the cover cloth; the area of the seat cushion is larger than the area of the support plate, and an annular portion is formed around the support plate; the opposite sides of the annular portion are turned toward the back of the support plate to form two positioning portions that are opposite and fit on the back of the support plate and two protruding portions that protrude outward from the support plate, and the positioning portions are fixed to the back of the support plate by a first nail gun, thereby realizing the positioning of the seat cushion and the support plate.

[0008] The external force squeezes the middle part of the support plate to cause the seat cushion to deform, so that the protruding part is turned toward the back side of the support plate and tightly adheres to the support plate; the protruding part is tightened to the inner side of the back side of the support plate by a drawstring, so that the peripheral edge of the seat cushion is gathered to the inner side of the back side of the support plate and remains relatively fixed with the support plate; the tightened drawstring makes the seat cushion automatically adapt to the shape of the support plate, reducing the difficulty of operation.

[0009] Preferably, the portion of the drawstring exposed from the covering is fixed to the support plate by a second nail gun, so that it is continuously kept tightened, thereby keeping the annular portion always tightly attached to the inner side of the back side of the support plate; the second nail gun can ensure the quality of the fixation and prevent the tightened drawstring from loosening, thereby avoiding the outer periphery of the seat cushion from sliding relative to the support plate.

[0010] Preferably, the portion of the drawstring exposed from the cover is directly attached to the support plate and fixed by a second nail gun; the drawstring is kept continuously tightened to prevent the outer periphery of the seat cushion from sliding relative to the support plate.

[0011] Preferably, the portion of the pull cord exposed from the cover is attached to the cushion and fixed to the support plate by a second nail gun; the pull cord is kept continuously tightened to prevent the outer periphery of the seat cushion from sliding relative to the support plate.

[0012] Preferably, the portion of the drawstring exposed from the cover is knotted to keep it continuously tightened to prevent the drawstring from loosening, thereby keeping the annular portion always in close contact with the inner side of the back of the support plate to prevent the outer periphery of the seat cushion from sliding relative to the support plate.

[0013] Preferably, a cloth cover is connected to the outer periphery of the cover cloth, and a drawstring is passed through the cloth cover, with both ends of the drawstring exposed from the cloth cover, so as to facilitate tightening the drawstring and keep the seat cushion and the support plate relatively fixed.

[0014] Preferably, the drawstring is connected to the outer periphery of the cover cloth by sewing, and both ends of the drawstring are exposed outside the cover cloth, which makes it easy to tighten the drawstring and keep the seat cushion and the support plate relatively fixed.

[0015] Preferably, the soft cushion is made of sponge material or rubber material; and the covering cloth is made of non-woven fabric material or leather material.

[0016] Preferably, both ends of the pull rope are exposed outside the covering cloth on the positioning portion, which is convenient for workers to operate and does not need to change direction when positioning and fixing the seat cushion and support plate.

[0017] The beneficial effects of the utility model using the above technical solution are:

[0018] The present invention provides a new type of chair seat. Compared with a chair seat in which a seat cushion and a support plate are fixed with a circle of nails, the chair seat uses nails to position the flanges on both sides of the seat cushion, which not only reduces the amount of nails used, avoids nail waste, and reduces the difficulty of processing; the pull rope is tightened so that the peripheral edges of the seat cushion are gathered to the inner position of the back side of the support plate and remain relatively fixed to the support plate, which reduces the difficulty of flanging the seat cushion on the support plate and is conducive to ensuring that the flanging width is uniform, while simplifying the processing steps and improving production efficiency.

[0025] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] Descriptions based on orientation in the present invention, such as "the reverse side of the support plate 1", are described when the support plate 1 is installed on a chair seat in normal use, that is, the side of the chair seat on which the user sits is the front side.

[0028] The utility model provides a new type of chair seat, such as Figure 1-5As shown, it includes a support plate 1 and a seat cushion 6 fixed on the front of the support plate 1; the support plate 1 is a support component of the seat; the seat cushion 6 includes a cover cloth 2 and a soft pad 3 arranged in sequence on the front of the support plate.

[0029] like Figure 1-3 As shown, a circle of drawstring 21 is connected to the outer edge of the cover cloth 2; both ends of the drawstring 21 are exposed to the edge of the cover cloth 2; specifically, there are two ways to connect the drawstring 21 to the edge of the cover cloth 2; the first connection method is that the outer peripheral edge of the cover cloth 2 is turned over to the inside of the cover cloth 2 and connected to the inside of the cover cloth 2 to form a circle of cloth cover, and the drawstring 21 is passed through the inside of the cloth cover, and the cloth cover is exposed at both ends. The drawstring 21 can be tightened by pulling the part of the drawstring 21 exposed to the cloth cover, so that the seat cushion 6 is retracted to the inner side of the back of the support plate 1 and kept close to it; the second connection method is to directly connect the drawstring 21 to the outer peripheral edge of the cover cloth 2 by sewing, and the cover cloth 2 is exposed at both ends of the drawstring 21. The seat cushion 2 is contracted by pulling the exposed part of the drawstring 21, so that the outer peripheral edges of the seat cushion 6 are all gathered to the inner side of the back of the support plate 1 and kept close to it.

[0030] like Figure 2-3 As shown, the area of the seat cushion 6 is larger than the support plate 1, and the seat cushion 6 forms an annular portion 5 around the support plate 1; the opposite sides of the annular portion 5 are turned toward the back of the support plate 1 to form two positioning portions 51 that are opposite and fit the back of the support plate 1 and two protruding portions 52 that protrude outward from the front of the support plate 1, and the positioning portions 51 are fixed to the back of the support plate 1 by the first nail 4a; the positioning portions 51 are positioned in a way of positioning on both sides so that the seat cushion 6 will not be loose on the support plate 1; now there are only two protruding portions 52 on the seat cushion 6 that are not fixed to the support plate 1, so in order to The entire seat cushion 6 is fixed on the support plate 1. The middle part of the support plate 1 can be squeezed by external force to cause the contact part between the seat cushion 6 and the support plate 1 to be compressed. The elasticity of the seat cushion causes the protruding part 52 to be turned over to the back side of the support plate 1; the protruding part 52 is tightened to the inner position of the back side of the support plate 1 by the pull rope 21, so that the peripheral edges of the seat cushion 6 are all gathered to the inner position of the back side of the support plate 1 and remain relatively fixed with the support plate 1; tightening the pull rope 21 makes the seat cushion 6 adapt to the shape of the support plate 1 by itself, so that the width of the turned over of the seat cushion 6 is uniform, while reducing the amount of nails used and reducing the processing difficulty.

[0031] Furthermore, after the pull cord 21 tightens the protruding portion 52, in order to prevent the pull cord 21 from loosening and affecting the fixing effect of the seat cushion 6 and the support plate 1, the portion of the pull cord 21 exposed from the cover 2 is fixed to the support plate 1 by a second nail 4b, so that it is continuously tightened, thereby keeping the annular portion 5 always in close contact with the inner position of the back side of the support plate 1; the second nail 4b can ensure the quality of the fixation and prevent the pull cord 21 from loosening, thereby preventing the outer peripheral edge of the seat cushion 6 from sliding relative to the support plate 1; specifically, there are three ways to fix the portion of the pull cord 21 exposed from the cover 2 ; The first way is to directly stick the part of the drawstring 21 exposed from the cloth 2 on the support plate 1 and fix it through the second nail 4b; the second way is to stick the part of the drawstring 21 exposed from the cloth 2 on the cushion 3 and fix it to the support plate 1 together through the second nail 4b; the third way is to tie a knot in the part of the drawstring 21 exposed from the cloth 2, and prevent loosening by the mutual friction of the drawstring 21; all three ways can keep the drawstring 21 continuously tightened, so that the periphery of the seat cushion 6 is all retracted to the inner position of the back side of the support plate 1 and remains relatively fixed to the support plate 1.

[0032] Furthermore, the cushion 3 is made of sponge material or rubber material, which is soft and elastic with large variability; the cover cloth 2 is made of non-woven fabric material or leather material, which is light, soft, non-toxic, non-irritating and wear-resistant.

[0033] Furthermore, after completing the positioning operation of the seat cushion 6 and the support plate 1, the positioning portion 51 faces the operator. In order to facilitate the worker's operation, the two ends of the pull rope 21 are exposed outside the cover cloth 2 on the positioning portion 51; this design makes it convenient for the worker to tighten the pull rope 21 without adjusting the direction, thereby reducing the processing difficulty.

[0034] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
