Abstract

There is provided a seat cushion for a chair that does not need to be fixed with a string or the like, has a simple structure, and does not impair the design of the chair.
An anti-slip process is performed in which an anti-slip material 12 made of a synthetic resin or a rubber material is printed in an arbitrary pattern on at least one surface of a cushion member 11 having a size that can be laid on a seat surface of a chair. ing. For this reason, only by laying on the seat surface of the chair, it is prevented from slipping when the user sits down, and since it has a simple structure, the influence on the design of the chair can be kept small.

Description

  The present invention relates to a seat cushion laid on a seat surface of a chair.

  Conventionally, as a cushion arbitrarily laid on the seat surface of a chair, a cushion-like cushion is used. In other words, this type of cushion is one in which cotton or urethane foam is wrapped with a bag-like fabric and stitched, and is fixed with a string or hook-and-loop fastener (see, for example, the following patent document).

  However, this type of cushion generally has a large volume, so when used in a chair that emphasizes design, the design of the chair is likely to be impaired. Met.

  The present invention has been made in view of the above points, and its technical problem is to provide a cushion that does not need to be tied with a string and that has a simple structure and does not impair the design of the chair. There is.

  As a means for effectively solving the technical problems described above, the seat cushion for a chair according to the present invention is characterized in that at least one side of a cushion body that can be laid on the seat surface of the chair is subjected to slip prevention processing. To do. According to this configuration, the anti-slip surface is pressed against the seat surface of the chair by the weight of the user and is slid only by laying on the seat surface of the chair with the anti-slip side down. It is not necessary to fix with a string etc., As a result, the influence on the designability of a chair can also be suppressed lightly as a simple structure.

  As a preferable configuration in the present invention, it is assumed that the anti-slip processing is performed by printing an anti-slip material made of a synthetic resin or a rubber material in an arbitrary pattern. In this way, the anti-slip material itself can have a design, and can exhibit an excellent anti-skid effect on the seat surface of the chair made of wood, synthetic resin, or metal. it can.

  As another preferable configuration in the present invention, the cushion body is formed of a single felt. If it does in this way, the influence on the designability of a chair can be restrained remarkably small as a simpler structure.

  As another preferable configuration in the present invention, an exterior material made of woven fabric or felt is filled with an interior material having cushioning properties. If it does in this way, the function as a cushion can be improved.

  According to the seat cushion for a chair according to the present invention, it is simply laid on the seat surface of the chair, so that it is prevented from slipping when the user is seated. The influence on the designability of can be kept small.

  Hereinafter, preferred embodiments of a seat cushion for a chair according to the present invention will be described with reference to the drawings. 1 is a plan view showing a first form of a seat cushion for a chair according to the present invention, FIG. 2 is a bottom view, FIG. 3 is a cross-sectional view taken along line III-III ′ in FIG. These are perspective views of a use condition.

  That is, the seat cushion 1 for a chair according to the first embodiment is provided with an anti-slip process using an anti-slip material 12 on one side of a cushion body 11 having a size that can be laid on the seat surface 101 of the chair 100 illustrated in FIG. It was made.

  Specifically, the cushion body 11 is formed of a single sheet-like felt having a circular shape as shown in FIG. 1 or 2 and a thickness of about 2 to 5 mm.

  The anti-slip material 12 is made of a synthetic resin material or rubber material having a large friction coefficient, typically PVC (polyvinyl chloride), and is formed on one side of the cushion body 11 by a silk screen printing method. For example, a portion of the anti-slip material 12 where the surface of the felt is exposed forms a clock face pattern.

  That is, the seat cushion 1 according to the first embodiment is used by being laid on the seat surface 101 of the chair 100 as shown in FIG. 4 with the surface on which the anti-slip processing by the anti-slip material 12 is performed on the lower side. Therefore, when the seat surface 101 of the chair 100 is made of wood, synthetic resin, or metal, the coldness and hardness when the user is sitting are eliminated, and the sitting comfort is improved.

  Further, when the weight of the user acts on the cushion body 11 and the anti-slip material 12 comes into close contact with the seat surface 101 of the chair 100, the anti-slip material 12 generates a large frictional force. The seat cushion 1 can be effectively prevented from sliding forward on the seating surface 101 when sitting in a posture with the back resting on the backrest 102 of the seat.

  In addition, since the cushion body 11 has a simple structure made of a thin sheet-like felt, even if the cushion body 11 is used for the chair 100 with emphasis on designability as shown in FIG. 4, the influence on the designability of the chair 100 is minimized. be able to.

  Next, FIG. 5 is a plan view showing a second embodiment of the chair seat cushion according to the present invention, FIG. 6 is a bottom view, and FIG. 7 is a cross-sectional view taken along the line VII-VII ′ in FIG. is there.

  In the seat cushion 1 for the chair according to the second form shown in these drawings, the place different from the first form described above is that the cushion body 11 is excellent in cushioning between the front and back exterior materials 111 and 112. The interior material 113 is filled and the outer peripheral portions of the exterior materials 111 and 112 are stitched 114. For example, a felt having a thickness of about 2 mm is preferably used for the exterior materials 111 and 112, and an elastic foam such as urethane foam having a thickness of about 10 mm is preferably used for the interior material 113.

  The exterior material 112 on the back surface of the exterior materials 111 and 112 is subjected to anti-slip processing by a silk screen printing method or the like using the anti-slip material 12 made of PVC or the like having a large friction coefficient, as in the first embodiment. Has been.

  That is, the seat cushion 1 according to the second embodiment is also used by laying on the seat surface 101 of the chair 100 shown in FIG. 4 with the surface on which the anti-slip processing by the anti-slip material 12 is performed on the lower side. In addition to the same effect as the first embodiment, the interior material 113 filled in the cushion body 11 ensures a superior cushioning property as compared to the felt alone as in the first embodiment.

  Needless to say, the anti-slip material 12 is not limited to the one having a clock face motif as in the illustrated example.

It is a top view which shows the 1st form of the seat cushion for chairs concerning this invention. It is a bottom view which shows the 1st form of the seat cushion for chairs concerning this invention. It is sectional drawing cut | disconnected by the III-III 'line | wire in FIG. It is a perspective view of the use condition which shows the 1st form of the seat cushion for chairs which concerns on this invention. It is a top view which shows the 2nd form of the seat cushion for chairs concerning this invention. It is a bottom view which shows the 2nd form of the seat cushion for chairs concerning this invention. It is sectional drawing cut | disconnected by the VII-VII 'line | wire in FIG.
