Description

  In particular, the present invention relates to a cushion used for a seat portion of a chair installed outdoors, and more particularly, to a quick-drying cushion that can be quickly dried even when rained or showered.

  In particular, chairs installed outdoors are often made of plastic or metal chairs because it takes a long time before the seating becomes possible due to rain water. However, these plastic or metal chairs have poor cushioning properties, and thus cannot be used for a long time, and the sitting comfort is remarkably impaired.

  An all-weather type chair provided with a seat having cushioning properties is disclosed in Japanese Patent Application Laid-Open No. 2003-204835 (Patent Document 1). This chair consists of a seat cushion provided on the seat, consisting of a water-permeable cushion placed on the seat and an outer skin that covers this cushion except for the lower side. When rainwater enters the cushion body through the gap or the skin, the rainwater is drained so as to pass to the lower part of the cushion body.

Japanese Patent Laid-Open No. 2003-204835

  The chair disclosed in Patent Document 1 prevents rainwater from entering by covering the cushion body with a non-permeable skin. Chairs are required to have design and fashionability. In normal cases, it is desired to use a fabric having a favorite color or pattern for the seat. However, the non-permeable skin as disclosed in Patent Document 1 is different from the woven fabric, and thus hinders design and fashionability. In addition, since fabrics having fashionability generally have water retention properties, rainwater penetrates into the fabrics when it rains, so that there is a problem that clothes and the like get wet when sitting in the rain. Furthermore, since the woven fabric once retained requires a long time to dry, there is a problem that it cannot be used during that time.

  The problem to be solved by the present invention is that it is possible to use a fabric having design and fashionability for the epidermis, and to quickly dry by suppressing the intrusion of rainwater and draining it. To provide a cushion.

  Therefore, in the quick-dry cushion according to the present invention, the cushion material is covered with a woven fabric, and the woven fabric is subjected to a water-repellent process applied or impregnated with a water-repellent agent, and a bottom plate provided on the bottom surface of the cushion material. A peripheral edge is fixed, a waterproof sheet is interposed between the fabric and the cushion material, and an edge portion of the waterproof sheet is fixed to a peripheral edge of the bottom plate, and a drain outlet is formed on the peripheral edge of the bottom plate. The gist is to drain the water flowing between the waterproof sheet and the fabric.

  Further, the drainage port is formed by being recessed from the end surface of the bottom plate, a waterproof sheet is provided along the inner surface of the drainage port, and the opening is covered with a woven fabric, and a space is formed between the drainage port and the waterproof sheet. .

  Furthermore, it is desirable that the cushion material be a three-dimensional three-dimensional network having water permeability and elasticity.

  According to the quick-drying cushion of the present invention, since the fabric covering the cushion material is water-repellent, it is possible to prevent rainwater from entering during rainy weather. Even if rainwater may pass through the fabric slightly in the case of long time or heavy rain, since the waterproof sheet is interposed between the fabric and the cushion material, it does not reach the cushion material, Since the water is quickly drained from the drain port formed on the periphery of the bottom plate along the surface of the waterproof sheet, it is possible to prevent the fabric and the cushion material from accumulating due to rain water or the like. For this reason, since a quick-drying cushion hardly penetrates rainwater or the like, the time until drying is remarkably shortened, so that quick-drying properties can be provided. Furthermore, since the design and the fashion according to the user's preference can be freely selected as the fabric covering the cushion material, it can be used for a wide range of applications. Further, since the cushion material is covered with the woven fabric, the sitting comfort can be improved.

  Moreover, since the drainage port formed by being depressed from the end face of the bottom plate has the waterproof sheet along the inner surface, rainwater or the like can be drained without entering the bottom plate. Further, since the space is formed between the opening and the waterproof sheet by covering the opening of the drainage port, rainwater and the like can be drained smoothly.

  Furthermore, even if it is a chair installed outdoors by making it a three-dimensional three-dimensional structure network having water permeability and elasticity as a cushioning material, the cushioning property is improved and the sitting comfort is greatly improved. It is possible to satisfy the user.

  The quick-drying cushion according to the present invention has a cushion material covered with a woven fabric, and the woven fabric is subjected to a water-repellent process applied or impregnated with a water-repellent agent, and a peripheral edge is provided on a bottom plate provided on the bottom surface of the cushion material. A waterproof sheet is interposed between the fabric and the cushion material, and an end edge of the waterproof sheet is fixed to the peripheral edge of the bottom plate, and a drain outlet is formed on the peripheral edge of the bottom plate, The water flowing between the waterproof sheet and the fabric is drained.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. A quick-drying cushion 1 shown in FIG. 1 includes a cushion material 2, a fabric 3, a waterproof sheet 4 interposed between the fabric 3 and the cushion material 2, and a bottom plate 5. This quick-drying cushion 1 is used for the seat part of the chair 6 mentioned later as an example.

  As the cushion material 2, for example, a three-dimensional mesh cushion material made of a three-dimensional three-dimensional network is suitable. This three-dimensional reticulated cushion material is made of elastic elastic synthetic resin (polyetherester fiber), etc., and forms a large number of linear loops by winding a solid or hollow continuous linear body made of elastic synthetic resin In addition, since the striatum loop is a three-dimensional structure network joined to each other, and gaps are formed between a large number of striatum loops, water can be passed through the gaps. It has excellent water permeability. Moreover, it has necessary elastic force and air permeability. The density of the three-dimensional structure network is set to about 20 kg to 40 kg / cubic meter, and a desired hardness or repulsive force can be obtained by this density. As this three-dimensional reticulated cushion, a commercial name “Breath Air” (manufactured by Toyobo Co., Ltd.) can be used. In addition, as the cushion material 2, you may use other raw materials, such as a water-permeable urethane foam.

  As shown in FIG. 1, the cushion material 2 is formed in a substantially hemispherical shape having a central portion as a vertex. The bottom surface of the cushion material 2 is in contact with the bottom plate 5. The bottom plate 5 is formed in a planar shape having a shape corresponding to the seat portion of the chair, using a material such as wood or synthetic resin.

  At the periphery of the bottom plate 5, a plurality of drain ports 5 a as shown in FIG. 2 are formed on each of the four sides of the bottom plate 5. The drain port 5a is formed in a shape that is recessed in a substantially semicircular shape from the end surface of the bottom plate 5 inward. Further, a plurality of air circulation holes 5 b are formed in the central portion of the bottom plate 5.

  The surface of the cushion material 2 described above is covered with a waterproof sheet 4, and the edge of the waterproof sheet 4 is fixed to the periphery of the bottom plate 5. And the edge part vicinity of the waterproof sheet 4 corresponding to the drain port 5a formed in the bottom plate 5 is along the inner surface of the drain port 5a. As the waterproof sheet 4, any material such as non-permeable vinyl chloride, polyester, nylon, Teflon, or silicon can be appropriately selected and used.

  The fabric 3 is coated on the waterproof sheet 4 coated on the surface of the cushion material 2 in this way. The peripheral edge of the fabric 3 is fixed to the bottom plate 5. Since the vicinity of the periphery of the fabric 3 covers the opening of the drainage port 5 a, a space portion 9 is formed between the waterproof sheet 4. A reinforcing band 7 for reinforcing the end portion is fixed to a portion where the fabric 3 and the waterproof sheet 4 on the peripheral edge of the bottom plate 5 are fixed. Further, a drainage member 8 is provided at a position corresponding to the space portion 9. For this drainage member 8, for example, eyelets are preferably used, and a central through hole communicates the drainage port 5a with the outside so that water accumulated in the drainage port 5a is drained to the outside.

  The woven fabric 3 is a woven fabric for a chair, and is selected from various woven fabrics having a color, a pattern, a weaving method, and the like according to a user's request, which are suitable for a chair. The fabric 3 is subjected to a well-known water repellent process in which a surface is coated or impregnated with a water repellent such as fluorine, silicon, or silicon dioxide. Accordingly, the fabric 3 can obtain a water repellent effect with a contact angle of about 150 degrees, and can repel rainwater and the like.

  The quick-dry cushion 1 configured as described above is attached to, for example, a chair 6 as shown in FIG. The chair 6 is a generally used chair configuration, and detailed description thereof is omitted. The chair 6 includes a cushion mounting part 61 and a backrest mounting part 62, two front leg parts 63 and two rear leg parts 64. The cushion mounting portion 61 is supported by the front leg portion 63 and the rear leg portion 64, and the backrest mounting portion 62 is supported by the rear leg portion 64. The cushion mounting portion 61 is formed in a substantially rectangular frame shape, and a plurality of support members 61a are provided in the middle, and between them penetrates in the vertical direction. The quick-drying cushion 1 is placed on the step on the inner peripheral portion of the cushion mounting portion 61 and the support member 61a. For example, a hook-and-loop fastener is attached to the bottom plate 5 and the support member 61a of the quick-dry cushion 1 so as to be detachable. In addition, it is desirable to form a recess 61b at a position corresponding to the drainage port 5a of the quick-drying cushion 1 on the inner peripheral portion of the cushion mounting portion 61 so that water drained from the drainage port 5a is circulated. .

  Next, the operation of the quick drying cushion 1 according to the present invention will be described. As shown in FIG. 3, water 20 such as rain water or shower falls on the fabric 3 from above the quick-dry cushion 1. In a normal case, as shown in FIG. 3A, the water drops 20a fall due to the water repellent effect. However, when the water 20 is in a large amount or dropped for a long time, the water 20 rarely enters through the gaps in the fabric 3. As shown in FIG. 3B, the water 20 reaches the waterproof sheet 4, but the waterproof sheet 4 is impermeable to water, so that the water 20 is prevented from entering the cushion material 2. The water 20 that has reached the surface of the waterproof sheet 4 passes between the waterproof sheet 4 and the fabric 3 in the side direction of the quick dry cushion 1 along the slope because the quick dry cushion 1 is formed in a substantially hemispherical shape. Flowing. Thereafter, as shown in FIG. 5, the water 20 reaches the drain 5a and is drained.

  Thus, even when the water 20 has fallen for a long time or has fallen for a long time, or even rarely enters the fabric 3, the water 20 is drained without entering the cushion material 2, so that the water 20 can be discharged in a short time. Can be dried.

  In normal cases, as described above, the drying time can be shortened by the water repellent effect of the water-repellent fabric 3 alone, and even when a small amount of water enters the fabric 3, the waterproof sheet 4 Therefore, the intrusion into the cushion material 2 is prevented and drained, so that drying can be performed in a short time. When it is desired by the user to be completely dried, as shown in FIG. 6, it can be stood against the wall 30 or the like and dried. In this case, the water 20 that has reached the waterproof sheet 4 falls downward due to the inclination, and eventually reaches one side of the quick-dry cushion 1 in a concentrated manner. Thereafter, as described above, the water 20 is quickly drained from the lower drainage port 5a. As a result, the drying time can be shortened.

  Although the present invention has been specifically described above based on the embodiments, it is needless to say that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof. In the above-described embodiments, the example in which the quick-dry cushion is applied to the chair has been described. The quick-drying cushion may be circular or polygonal.
