Description

  The present invention relates to a chair. More specifically, the present invention relates to a chair that can function as a partition for partitioning a space, for example, by stacking a plurality of chairs.

  Conventionally, chairs that can be stacked in the upward direction are known (for example, Patent Document 1). A conventional stackable chair is a single unit that can save space when the chairs are stored. It is configured such that the seat plate of another chair can be stacked on the chair seat plate.

  Conventionally, a chair has been known in which the shape of the chair is substantially square, and the stability and ease of sitting are improved (for example, Patent Document 2). A conventional square chair can be mounted on the top of one chair and can be stacked upwards to some extent.

JP 2005-152219 A JP 2008-5857 A

  However, the stackable chair described in Patent Document 1 is assumed to be stored in a closet or a warehouse when not used as a chair. For this reason, a storage space for storing unnecessary chairs is necessary, and this chair was not useful when not in use.

  Moreover, when the square chair described in Patent Document 2 is not used as a chair, it can be used as, for example, a table or a table by stacking a plurality of chairs. However, the top and bottom surfaces of the chair are formed in a flat surface with no irregularities, so that they are not stable when stacked.

  Therefore, at present, it is possible to stack a plurality of chairs stably to such an extent that they can function as partitions for partitioning spaces, for example, and can provide useful functions even when not used as chairs. A chair is required.

Therefore, as a result of intensive studies on the means for solving the problems of the prior art described above, the inventors of the present invention have made the chair a shape composed of a top surface, a bottom surface, and a side surface, provided a convex portion on the top surface, It was found that a plurality of chairs can be stacked in a stable manner by providing a recess on the top. Based on the above knowledge, the inventor came up with the idea that the problems of the prior art could be solved, and completed the present invention.
Specifically, the present invention has the following configuration.

The first embodiment of the present invention relates to a chair.
The chair of the present invention has a top surface 1, a bottom surface 2, and a side surface 3 that connects the top surface 1 and the bottom surface 2.
A convex portion 11 is formed on the top surface 1, and the convex portion 11 has a flat top surface and functions as a seat. In addition, a seat board is a part where a person's buttocks are placed when a person sits down on a chair.
A concave portion 21 having a shape corresponding to the convex portion 11 is formed on the bottom surface 2. In addition, the shape corresponding to the convex part 11 means that the convex part 11 can be fitted into the concave part 21.

  By having such a configuration, the present invention can fit the convex portion 11 formed on the top surface 1 and the concave portion 21 formed on the bottom surface 2 to stack a plurality of chairs. In addition, since the convex portion 11 is formed on the top surface 1 with such a large area as to function also as a seat, the fitting of the convex portion 11 and the concave portion 21 is very stable. Therefore, the chair of the present invention can be stacked stably enough to function as a partition.

  In the present invention, the side surface 3 is preferably composed of a front side surface 31, a rear side surface 32, a right side surface 33, and a left side surface 34. That is, the shape of the chair according to the present invention is preferably a hexahedron in which the convex portions 11 and the concave portions 21 are formed.

  By having such a configuration, the top surface 1 and the bottom surface 2 can be supported by the front side surface 31, the rear side surface 32, the right side surface 33, and the left side surface 34. Moreover, it becomes easy to stack up and down and right and left by making the shape of the chair a hexahedron. The chair of the present invention may have a regular hexahedron shape in which the top surface 1, the bottom surface 2, the front side surface 31, the rear side surface 32, the right side surface 33, and the left side surface 34 are all formed with the same shape and area. . Further, for example, the top surface 1, the bottom surface 2, the front side surface 31, and the rear side surface 32 are formed with the same shape and area, and the right side surface 33 and the left side surface 34 are formed with an area twice that of the top surface 1 and the like. It may be a hexahedron. Note that at least the top surface 1 and the bottom surface 2 preferably have the same shape and area.

  In the present invention, the area of the top surface of the convex portion 11 is preferably 50% or more and 90% or less of the area of the top surface 1.

  If the area of the top surface of the convex portion 11 is 50% or more and 90% or less of the area of the top surface 1, it is possible to secure the ease of sitting of the chair and the stability when the chairs are stacked.

  In the present invention, a magnet 4 is attached to a position corresponding to the top surface 1 and the bottom surface 2 inside the chair, and a position corresponding to the magnet 4 and the bottom surface 2 provided at a position corresponding to the top surface 1. It is preferable that either one of the magnets 4 provided in is an N pole and the other is an S pole.

  By having such a configuration, when the chairs are stacked, the chairs are not only affected by the frictional force caused by fitting the convex portion 11 of the top surface 1 and the concave portion 21 of the bottom surface 2 but also by the magnetic force of the magnet. Because it is bonded, the stability when the chairs are stacked is further improved.

  In the present invention, magnets 4 are attached to positions corresponding to the right side surface 33 and the left side surface 34 inside the chair, respectively, and correspond to the magnet 4 and the left side surface 34 provided at positions corresponding to the right side surface 33. It is preferable that one of the magnets 4 provided at the position to be operated is an N pole and the other is an S pole.

  By having such a configuration, when the right side surface 33 of a certain chair and the left side surface 34 of another chair are brought into contact with each other, they are bonded by the magnetic force of each other. For this reason, when a plurality of chairs are arranged in the horizontal direction, the chairs are not easily separated from each other.

  In the present invention, a weight 5 is preferably provided at a position on the bottom surface 2 side inside the chair.

  By having such a configuration, the center of gravity of the chair is located at the lower part of the chair. This improves the stability when the chairs are stacked.

  In the present invention, the top surface of the convex portion 11 may be polygonal.

  By making the top surface of the convex part 11 into a polygonal shape, it is possible to prevent the chair located above from rotating in the circumferential direction when the chairs are stacked. This improves the stability when the chairs are stacked.

The second embodiment of the present invention relates to a partition formed by stacking a plurality of chairs according to the first embodiment.
The chair 100 included in the partition of the present invention has a top surface 1, a bottom surface 2, and a side surface 3 connecting the top surface 1 and the bottom surface 2. The top surface 1 has a flat top surface and serves as a seat plate. A functioning convex portion 11 is formed, and a concave portion 21 having a shape corresponding to the convex portion 11 is formed on the bottom surface 2.
When stacking the plurality of chairs 100, the convex portion 11 of the top surface 1 and the concave portion 21 of the bottom surface 2 are fitted. Further, the side surfaces 3 of the chair 100 are brought into contact with each other and are arranged in the lateral direction. In this way, a partition for partitioning the space is formed by the plurality of chairs 100.

  Further, the partition is formed with a short chair 110 in which a convex portion 11 and a concave portion 21 are formed on the top surface 1 and the bottom surface 2, and two convex portions 11 and a concave portion 21 are formed on the top surface 1 and the bottom surface 2. It is preferable that at least one chaise longue 120 is included. Here, the shape of the convex portion 11 formed on the chaise longue 110 and the shape of the convex portion 11 formed on the chaise longue 120 and the shape of the concave portion 21 formed on the chaise longue 110 and the shape of the concave portion 21 formed on the chaise longue 120 are the same. It is.

  Thus, the strength of the partition is improved by forming the partition by combining the chaise longue 110 and the chaise longue 120. That is, two chaise lounges 110 can be stacked on the chaise lounge 120, or one of the recesses 12 of the other chaise lounge 120 can be superimposed on one of the projections 11 of one chaise lounge 120, so Compared with the case where it did, the connection strength of up and down, right and left can be improved.

  In addition, the side surface 3 of the chaise longue 110 is comprised from the front side surface 31, the rear side surface 32, the right side surface 33, and the left side surface 34, and the shape of the chaise longue 110 is the shape which formed the convex part 11 and the recessed part 21 in the regular hexahedron. In some cases, the shape of the chaise lounge 120 may be a shape in which the two chaise lounges 110 are integrally connected.
