Description

  The present invention relates to a cushion whose shape can be freely changed.

  In recent years, cushions that feel like marshmallows are gaining popularity as so-called healing goods. For example, as disclosed in Utility Model Registration No. 3100266 (Patent Document 1) and Utility Model Registration No. 3082016 (Patent Document 2), this cushion is made of, for example, foamed styrene in a cloth exterior. Filled with expanded beads having a particle size of 1 mm or less. Since foam beads exhibit fluidity in the exterior, the cushion is freely deformed when external pressure is applied, and it is supposed to give the user a healing feeling by expressing a strange feeling that can not be said at that time .

  However, the above-described cushion only changes the shape of the surface, that is, changes the degree of unevenness on the surface. For this reason, it is not possible to change the shape greatly, for example, bending the whole according to one's preference and application.

In view of this, Japanese Patent Application Laid-Open No. 2001-190384 (Patent Document 3) proposes a hug group that can be bent freely by adjusting the filling amount of foam beads. Separately, although foam beads are not used, Japanese Patent Application Laid-Open No. 2004-405 (Patent Document 4) has a cushioning material that can change the shape according to the user's preference and application. Proposed. This is a metal material such as an aluminum wire that can be deformed into a cushion material and can maintain a deformed shape as a core material.

  However, in the one disclosed in Patent Document 3, the variation of the change shape is at most about the L-shape, U-shape, or O-shape, so that there is a lack of interest. In addition, since it can be deformed by adjusting the filling amount of the foam beads, there is a problem that the shape cannot be maintained even if it is changed.

  Moreover, in what was disclosed by patent document 4, since the whole cushion is deformed by using a core material, the device which prevents a core material from piercing an exterior is needed. Therefore, there is a disadvantage that the structure is complicated in the cushion that should have a simple configuration. In addition, there is a problem in that the cost increases due to the necessity of the core material and the parts for holding it in the cushion.

  The present invention was devised to solve the above-mentioned conventional problems, and the entire cushion can be freely changed into various shapes, and after deformation, the shape can be maintained without using any core material. It is intended to provide a cushion that can be manufactured at low cost.

  In order to solve the above-mentioned problems, the cushion according to the present invention is formed in an annular shape and has a narrowed portion formed in at least five places, and an inner peripheral edge is provided with a string body having elasticity over the entire circumference. The inside of the exterior is filled with a granular filler having fluidity, and the whole can be bent and deformed with the respective narrowed portions as bending points.

  With this specific matter, the cushion of the present invention can change the overall shape to an arbitrary shape by the contraction force exerted by the elastic string provided on the inner peripheral edge of the exterior over the entire circumference. In addition, the deformed shape is maintained without using a core material. As the elastic cord body, for example, a rubber cord is suitable, but an annular coil spring (made of metal or synthetic resin) having an extremely small diameter can also be adopted.

  As said granular filling, a foam bead can be used. Examples of the expanded beads include what are generally called powder beads in the market in which synthetic resins such as polystyrene, polyethylene, and polypropylene are expanded. Further, the particle diameter may be as fine as 1 mm or less, or may exceed 1 mm. The granular filler is not limited to foam beads as long as it has fluidity, and for example, a natural material such as buckwheat straw or rice husk can be used as it is or after being pulverized into fine particles.

  Further, as the exterior, a fabric having elasticity can be used. By using such a fabric, the volume of the enormous portion easily changes in particular, so that the granular filler flows smoothly during deformation, and deformation becomes easier.

  According to the present invention, the entire cushion can be freely changed into various shapes, and after deformation, the shape can be held without using any core material, and the cushion can be manufactured at low cost. Can be provided.

  Embodiments of the present invention will be described below with reference to the drawings.

  1A and 1B show a cushion according to the present embodiment, in which FIG. 1A is a plan view, FIG. 1B is a front view, FIG. 1C is a right side view, and FIG. It is an end elevation in alignment with line II-II in).

  The cushion 1 is formed in an annular shape and has a narrow portion 21 formed in 10 locations, and a fluidity is provided in the exterior 2 in which a string 4 having elasticity is provided on the entire inner periphery. Is filled with a granular filler 5 having the stenosis portion 21 as a bending point, and the whole can be bent and deformed.

  The exterior 2 is formed in a hollow ring shape by sewing 20 adjacent fabrics 22 that are cut into a substantially fan shape and sewing the peripheral edges adjacent to each other. A sewn portion P between the fabrics 22 adjacent in the circumferential direction is a narrowed portion 21.

  Further, as shown in FIG. 2, an elastic string 4 is sewn on the inner periphery of the outer periphery 2 (on the inner space side of the exterior 2) over the entire circumference. As the elastic string 4, for example, a rubber string is preferable from the viewpoint of ease of sewing work, but it may be a coil spring having a very small diameter made of metal or synthetic resin. Moreover, it is not limited to each said material if it is string-like and exhibits a stretching property. Further, in the above example, the elastic string body 4 is sewn to the inner space side of the exterior 2 from the appearance, but the sewn location is not limited to this, and the outer periphery at the inner periphery of the exterior 2 is not limited thereto. You may sew in the form exposed to the space 3 on the surface. In that case, a design accent can be given to the cushion by coloring the string body 4 having elasticity.

  Note that the means for forming the exterior 2 is not limited to the example described above. For example, two circular fabrics are overlapped and the outer peripheral edges and the inner peripheral edges are sewn together, and all the inner peripheral edges are sewn together. A rubber ring 4 is sewn over the circumference to form a hollow annular body having a uniform cross-sectional shape, and then the constricted portion 21 is formed by partially constricting the annular body over 10 locations. Also good.

  The material of the exterior 2 is preferably a stretchable fabric as described above, but may be a synthetic resin sheet material, for example.

  As said granular filling, a foam bead can be used. Examples of the expanded beads include what are generally called powder beads in the market in which synthetic resins such as polystyrene, polyethylene, and polypropylene are expanded. Further, the particle diameter may be as fine as 1 mm or less, or may exceed 1 mm. The granular filler is not limited to foam beads as long as it has fluidity, and for example, a natural material such as buckwheat straw or rice husk can be used as it is or after being pulverized into fine particles. From the viewpoint of fluidity and feel during use, expanded beads having a particle size of 1 mm or less are preferred.

  Next, the usage method of the cushion material of the said structure is demonstrated.

  First, in the case of the shape shown in FIG. 1, it can be used, for example, as a cushion for a chair or as a cushion when sitting on the floor.

  The example shown in FIG. 3 has shown the case where the cushion 1 is folded up and down. When it changes to such a shape, it can be used as a pillow, for example.

  The example shown in FIG. 4 shows a case where the state shown in FIG. 3 is slightly opened and vertically raised. When it is changed to such a shape, it can be used when sleeping on the back of the chair while sitting down by wrapping around the back neck B.

  The example shown in FIG. 5 shows a state twisted twice from the state shown in FIG. Also when it changes into such a shape, it can be used, for example as a pillow.

  The example shown in FIG. 6 inserts a hand into the central space 3 in the state shown in FIG. 1, grasps one enormous portion 23, and pulls out the hand as it is. The case where it is made to fit in the space 3 is shown. By changing to such a shape, the whole has a flower shape. For example, when it is decorated as a cushion for a sofa, it can be seen and enjoyed.

  The usage method described above is merely an example, and can be changed into various shapes according to the idea of the user.

  In the above-described embodiment, the number of formation portions of the narrowed portion 21 is ten, but it is sufficient that there are at least five. However, in the case of 5 places, the shape change pattern is smaller than in the case of 10 places. When various changes are required, as shown in FIG. 7, it is preferable to form eight or more constricted portions 21. Further, the intervals between the narrowed portions 21 do not need to be equal. For example, as shown in FIG. 8, the narrowed portions 21 may be widened or narrowed.

The cushion which concerns on embodiment of this invention is shown, The figure (a) is a top view, The figure (b) is a front view, The figure (c) is a right view. It is sectional drawing which follows the II-II line | wire in FIG. It is a perspective view which shows the state which folded the cushion shown in FIG. 1 into two. It is a perspective view which shows the example which expands the cushion shown in FIG. 3 a little and uses it as a neck pillow. It is a perspective view which shows the state which twisted the cushion shown in FIG. 1 twice. It is a perspective view which shows the state which changed the cushion shown in FIG. 1 into the flower shape. It is a front view of the cushion concerning other embodiments. It is a front view of the cushion concerning other embodiments.
