Description

  The present invention relates to a chair that can use a plurality of seating surfaces.

  The chair has an appropriate height depending on the height. Therefore, chairs with a plurality of heights are prepared for a plurality of persons having a large height difference.

  For example, since a chair for adults is too high for an infant in a bathroom, there is a case where a chair made low for an infant is prepared like the chair described in Patent Document 1.

JP 2009-178280 A

It is not preferable to have a chair for adults and a chair for infants in the bathroom or undressing space because of the Japanese housing situation. In general, the bathroom and undressing space are about a few square meters, and there are washers, dryers, washbasins, detergents, cupboards such as shampoos, etc., and often just feel narrow.
It is not preferable to provide an adult chair and an infant chair in such a place, which makes a narrow space feel even narrower.

  In order to avoid the above situation, the present invention provides a first seat surface having a concave curved surface as a seating surface, and a second seat having a concave curved surface as a seating surface that is substantially perpendicular to and adjacent to the first seating surface. Proposed is a substantially rectangular parallelepiped chair comprising a seat surface and another surface, whether plate-shaped or frame-shaped.

  In addition, in the arrangement in which the first seat surface or the second seat surface is disposed on the upper surface and used as the seat surface, one surface among the other surfaces serving as the bottom surface is a chair in which a non-slip member is disposed on the floor contact region. Furthermore, the chair which can use the space enclosed by the other surface from this surface as a storage space where one surface in the other surface is a frame-like shape and allows access to small items. A chair provided with beams for reinforcing mechanical strength passed on both sides in a storage space between the first seat surface or the second seat surface adjacent to the entrance / exit surface and the bottom surface with respect to the seat surface. . A chair further comprising a drawer for taking in and out of the storage space, wherein the drawer is provided with a groove for avoiding this along a trajectory of the beam with respect to the drawer at the time of withdrawal. The second seat has two chairs. The anti-slip member is a long rubber member disposed along at least two sides of the second seat surface. The chair according to any one of claims 1 to 7, wherein the first seat surface and the second seat surface are different in height.

  According to the present invention mainly configured as described above, seats with different heights can be used in one chair, and there are two types of chairs: a high chair for adults and a low chair for infants. It is possible to avoid the need to provide a chair in the bathroom or undressing space, and to increase the available floor area of the bathroom or undressing space as much as possible.

<< Embodiment 1 >>
<Overview>
FIG. 1 is a diagram showing a basic configuration of the present embodiment, and shows a chair having a plurality of seating surfaces. The chair is not intended to limit the place of use in principle, but it is particularly effective in a place where the chair itself is slippery, such as a bathroom, and the chair itself is also wet.

<Configuration>
The present invention will be described with reference to FIG. The chair of the present invention includes a first seat surface 0101, a second seat surface 0102, and other surfaces 0103, 0104, 0105. Further, when the surface is used as the bottom surface of the chair, the surface has antiskid members 0106, 0107, 0108, 0109.

  The “first seating surface” 0101 has a concave curved surface as a seating surface. The concave curved surface is preferably designed such that the central portion of the seating surface is the lowest and the periphery gradually increases gradually toward the outside. This is to increase the effect of preventing the chair from slipping off even when the buttocks are calm and the seat surface is wet. In particular, when an infant who does not sit down sits on this seating surface, the concave curved surface should be relatively deep. For example, it is preferable that the concave curved surface is lower by about 3 to 10 millimeters than the highest part of the periphery. If it is too shallow, the effect is limited, and if it is too deep, the high part hits the bone of the buttocks and the sitting comfort becomes worse. In this figure, the first seating surface is designed to be lower than the second seating surface, which will be described later. When the seating surface for adults and the seating surface for infants are used properly, this first seating surface is used. The seating surface is preferably used as a seating surface for infants.

  The “second seating surface” 0102 is substantially perpendicular to and adjacent to the first seating surface. The seating surface is designed to have a concave curved surface in the same manner as the first seating surface. The appearance is almost the same as the first bearing surface. In the case of FIG. 1, the area of the second seat surface is smaller than that of the first seat surface. If the first seat is used for infants, it is still uncertain that the infant will be seated, so it is preferable to have a certain area so that it does not fall off the chair even if it is staggered, while the second seat is used for adults. In some cases, the legs and feet are already firm, and it cannot be assumed that they easily slide off the seating surface, so there is no problem even if the area is relatively small. Therefore, there is no problem even if the area of the second seat surface of this embodiment is smaller than that of the first seat surface. Further, the height difference between the central portion and the peripheral portion of the concave curved surface is not necessary as much as the first seat surface if the second seat surface is designed for adults. As described above, it is difficult to assume that an adult slides down from a chair, and there is no problem as long as it does not impair sitting comfort. Therefore, the height difference is about 2 to 5 millimeters.

  Further, the first seating surface may be provided on two or more surfaces that are substantially orthogonal to the second seating surface and are adjacent to each other. This is because if the surface that cannot be used as a seating surface is turned upside down, it must be turned over again, which is troublesome.

  Further, as shown in black in FIG. 1, it is preferable to dispose a non-slip member in the floor contact area on the chair surface that can be the bottom surface. This is because in a slippery place such as a bathroom, even if the chair is seated on the chair, there is a risk of falling from the chair by sliding the chair together with the floor. In this figure, the non-slip members 0106, 0107, 0108, and 0109 are arranged in a long shape along the side that does not constitute the curve of the first seating surface. In this case, therefore, the first seat surface has a shape with less curvature of the gutter, and is disposed at both ends in a cross-sectional view of the gutter shape. A typical example of the non-slip member is a rubber material, and a static frictional force can be applied to a strongly wet floor surface by giving a predetermined width. Moreover, it is preferable that it arrange | positions so that it may swell in a seat surface edge part. For example, it may be arranged so as to be raised by about 2 to 5 millimeters.

  Furthermore, by making this non-slip member long, it is possible to more effectively prevent the butt of a person sitting on the seat from slipping down. This is because rubber exhibits an effective frictional force against human skin. Further, when the chair is rolled on a wet floor surface, the part of the non-slip member can be used as a fulcrum or a support side. Plastic or the like is slippery on a wet floor and is not suitable for a fulcrum or the like, and rubber is convenient in this respect.

  Further, the chair surface including the seat surface may be provided with holes 0110 and 0111 for carrying the chair itself or turning it over so as to change the posture, which can be used for inserting a finger or the like.

  FIG. 3 is a perspective view when the chair according to the present embodiment or the chair according to the second embodiment is placed differently from FIG. In this figure, the second seating surface is arranged on the upper side instead of the first seating surface already described. In the second seating surface, all four sides around it are concavely curved, so the antiskid member is located at the four apexes of the second seating surface, and the four parts Members 03062, 03072, 03082, 03092 are arranged. In terms of design, these anti-skid members at the four apexes may use members that are integral with the long anti-skid members 0307, 0309, etc., constituting the first seating surface. Rather, a groove is provided along a straight side of the first seating surface and, in some cases, a surface facing this (this may be a different first seating surface), and rubber is embedded in the groove. It is preferable that the end is provided on the second seat surface and the cross-section portion of the rubber is used as an anti-slip member for the second seat surface. In FIG. 3, all the sides of the chair other than the four sides of the second seat surface are provided with anti-slip members in a long shape, and the first seat surface and the surface facing this (also referred to as the first seat surface). ) And three surfaces of the second seating surface substantially orthogonal to the two first seating surfaces can be used as the seating surface.

  Furthermore, as shown in FIG. 5, the above-mentioned hole 0512 (0212) is not only used for moving the chair by turning a finger or turning it over, but also by inserting the handle part of the hand 0501. It may be designed to be used for hooking and storing.

<< Embodiment 2 >>
<Overview>
FIG. 2 is a diagram showing a basic configuration of the present embodiment, where one surface of the chair is a frame shape and is an entrance / exit surface 0205 from which small items can be taken in and out, and is surrounded by a surface other than this surface. It is invention of the application based on the chair of Embodiment 1 comprised so that the internal space of a chair can be utilized as storage space. Like the chair of the first embodiment, the chair is not limited in principle to the place of use, but is particularly effective in places where the chair itself is slippery and the chair itself is easily wet, such as a bathroom. The entrance / exit surface 0205 is configured by providing a frame-like member 0216 adjacent to another surface that is substantially orthogonal.

<Configuration>
As shown in FIG. 2, the chair of the present embodiment has a non-slip member 0206,0207,0208,0209,0210,0211,0212,0213 or the like that is preferable if the first seat surface 02011 and the second seat surface 0202 are provided. And has an entrance / exit surface 0205. That is, the entrance / exit surface is a frame-like surface. In this embodiment, the entrance / exit surface is planar, and therefore, non-slip members 0210, 0211,0212, 0213 are arranged flush with this surface, and the surface opposite to this surface is the second seat surface 0202. It has become. As a preferred example, the surface facing the first seat surface 02011 is also the first seat surface 02012.

  As shown in FIG. 2, the entrance / exit surface 0205 has a frame shape. That is, it is composed of a frame-shaped member 0216 and an opening at the center thereof. This is because the strength of the chair may not be maintained unless the frame-shaped member is arranged, that is, the frame-shaped member is not disposed. In particular, when plastics are used as a member of a chair, it is difficult to maintain mechanical strength unless it is frame-shaped. This is because the material is brittle. In addition, the entrance / exit surface 0205 is surrounded by antiskid members 0210,0211,0212,0213 on the four sides, and the antiskid member is slightly higher than the arrangement surface, for example, 2 millimeters (lower than this is effective) (Small) to about 5 millimeters (if it is higher than this, it is too convex to interfere with it), and the anti-slip effect can be sufficiently exerted, and the frame-shaped entrance / exit surface 0205 itself, that is, the frame-shaped member is the floor surface Can be prevented from coming into contact with the floor. Furthermore, by providing holes 0210 and 0212 on both sides of the first seating surface, this hole can be placed at a low position, and even a short person such as an infant can carry this chair by lifting it sufficiently from the feet. it can. FIG. 4 shows an example in which the hole 0412 is used not only for carrying but also for catching a manual work 0401 or the like.

  FIG. 6 is a view showing a state in which the drawer 0602 is stored in the storage space inside the chair 0601 using the entrance / exit surface. By using the drawer, small items can be stored and taken out in an orderly manner. As mentioned in the topic, this drawer will contribute to the effective use of a small space such as a bathroom.

  FIG. 7 shows the internal structure of the optimal storage space in a state where the frame-like member portion (corresponding to 0216 in FIG. 2) on the entrance / exit surface is virtually removed. Reinforce mechanical strength between two first seat surfaces (possibly the second seat surface and other surfaces, and sometimes the first seat surface and other surfaces) arranged almost perpendicular to the entrance / exit surface A beam 0704 is provided. Although it is not clear in the figure, this beam is a plate-like beam that extends from the entrance / exit surface to the back side surface (for example, the second seating surface) and is fixed to the back side surface. Furthermore, rails 0702, 0703, 0705, and 0706 are provided so that the drawer is not obstructed by the frame member on the entrance / exit surface and is difficult to be pulled out or is not exposed in the vertical direction in the storage space. In other words, the drawer is put in and out with the rail sandwiched between the upper and lower sides. The height of the rail is substantially equal to the width of the frame member. When this rail restricts the vertical movement of the drawer (that is, when the vertical direction is considered as such), there is no special rail for restricting the left-right direction. This is because the position restriction in the left-right direction is performed using the beam 0704.

  FIG. 8 is a diagram for illustrating a drawer structure in the present embodiment. As is apparent from this figure, the drawer is provided with a groove 0801 for avoiding this along the trajectory of the beam with respect to the drawer when the drawer enters and exits the storage space. And with the cooperation of the beam 0704 and the groove 0801, the drawer is regulated in the left-right direction so that the drawer is not greatly exposed to the left and right, and the position is regulated in the vertical direction by the above-mentioned rail, and the drawer is not greatly exposed. Smooth entry / exit is realized by having a degree of freedom. Therefore, even if the top and bottom of the drawer turns 90 degrees or 180 degrees by the operation of changing the orientation of the chair, the drawer can be stably located in the storage space of the chair.

  It is preferable that holes are provided in the bottom surfaces 08031 and 08032 of the drawer in FIG. 8 so that water stays on the bottom surface and the inside of the drawer is kept clean. In addition, it is preferable to comprise so that the water discharged | emitted from here may be discharged | emitted outside the chair from the hole (for catching a finger | toe or a hand hook etc.) provided in each surface of the chair. Further, it is preferable that a handle 0804 is provided so that the drawer can be easily put in and out.

  Drawer rails 0805 and 0806 are preferably provided on the outer surface side of the bottom surface of the drawer in FIG. This may or may not continue to the back side along the bottom surface of the drawer as a rail, but is preferably provided at least on the bottom surface on the near side of the drawer. This is to prevent the drawer from easily slipping out when the drawer rails 0805 and 0806 are caught on the frame-like member on the entrance / exit surface (corresponding to 0216 in FIG. 2) after the drawer is pushed into the storage space. Serves as a stopper. The height of the rail is preferably about 2 to 5 mm. This is because if the length is shorter than this, the catch is weak, and if it is higher, the catch is too much.

  The rails 0702, 0703, 0705, and 0706 described with reference to FIG. 7 are provided such that the height from the ground contact surface is, for example, about several millimeters lower than the height from the ground contact surface of the frame-like member of the entrance / exit surface (for example, 2 The length of the drawer slides on the upper edge of the frame member of the entrance / exit surface when moving the drawer into the storage space. At the moment when the full length of the bottom of the drawer finally fits in the storage space, the bottom of the drawer is detached from the top edge of the frame member and the whole falls on the rail 0702, 0705 or 0703, 0706, The drawer rail provided on the bottom surface of the drawer firmly abuts against the frame member on the entrance / exit surface, thereby preventing the drawer from slipping out of the storage space unintentionally.

<Effect>
According to the present invention mainly configured as described above, seats with different heights can be used in one chair, and there are two types of chairs: a high chair for adults and a low chair for infants. It is possible to avoid the need to prepare a chair in the bathroom or undressing space, and it is possible to accommodate small items that must be kept in the bathroom or undressing space in the chair, and the chair can be moved or turned over. However, the contents of the storage space can be easily prevented from jumping out.
