Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stool that can be used as a chair or a table, and more particularly to a structure of a stool that can be stacked stably while ensuring a degree of freedom in design.

[0002]

2. Description of the Related Art Conventionally, in a stool having a main plate as a seat portion or a top plate and legs extending downward from the main plate, various contrivances have been made for stacking a plurality of stools. For example, JP-A-8-11215
The chair described in No. 5 is provided with four legs extending downward from the outer edge of the main plate, and the base portions of the legs are bent to project outward from the outer edge of the main plate. You can stack other chairs on top of it.

On the other hand, the chair described in Japanese Patent Application Laid-Open No. 5-146340 has a ring-shaped frame having a size that allows the main plate to pass through, and extends downwardly and laterally from the vicinity of the central portion of the lower surface of the main plate, and the lower end has the frame. And one pedestal connected to the. In this type of chair, in order to avoid the pedestal from interfering with the main plates of other chairs when stacking a plurality of chairs, the main plate should be positioned directly above the pedestal from its outer edge toward the center. An extending notch is formed.

Further, the chair described in Design Registration No. 917861 is provided with three legs extending downward and laterally inclined from a position near the central portion of the lower surface of the main plate, and the main plate has no legs. Three notches are formed with the pitch shifted in the circumferential direction.

[0005]

In the case of a stool such as a chair in which the base of the leg is bent so as to protrude outward from the outer edge of the main plate, it is possible to stack a plurality of stools in a well-balanced center of gravity. , Since it is necessary to project the base of the leg outward from the outer edge of the main plate, the degree of freedom in design is restricted, and in the case of a chair, it interferes with sitting. Further, even in the case of a table, if the base of the leg protrudes outward from the outer edge of the main plate, it will be a hindrance to use.

On the other hand, in a stool such as a chair in which one pedestal extends obliquely downward from the vicinity of the central portion of the lower surface of the main plate and a notch is formed in the main plate, the pedestal becomes an obstacle during its use. However, since each stool has only one pedestal piled up on top of each other to stack the stools, there is a drawback that the center of gravity balance becomes unstable and easily collapses.

Further, in the above-mentioned conventional chair structure in which the same number of notches as the legs are formed on the main plate, the positions at which the legs and the notches are arranged are shifted in the circumferential direction, so that a maximum of four stacks can be stacked. Although it is possible, it has the drawback of poor storage because it is not possible to stack more than 5 chairs.

Further, when the legs of the stool are fixed to the lower surface of the main plate, if the main plates are stacked and the stools are stacked, the pitch interval of the stack becomes narrow,
It is necessary to set the leg openness to a certain angle or more, which limits the height of the stool and the degree of freedom in design, and causes the leg to weaken against the load from above.

Further, when the slanted legs are brought into contact with each other and the stools are stacked, the stacked stools become unstable, and in the case of legs having a rectangular cross section, the legs are fitted into each other and it is difficult to pull them out. .

Therefore, an object of the present invention is to provide a stool which can be stacked stably in good balance without deteriorating the feeling of use and the degree of freedom of design, and the number is unlimited.

[0011]

In order to solve the above problems SUMMARY OF THE INVENTION The present invention includes a main plate, Bei example and a plurality of legs extending from the lower surface inclined downward and the side of the main plate, wherein The outer edge of the main plate is formed with a plurality of notches that engage with the legs of another stool when a plurality of stools are stacked, and are separated from the lower surface of the main plate to have a plurality of stools on the legs. A stool with a stopper that contacts the main plates of other stools when they are stacked and controls the pitch interval between the main plates.
There is a notch formed on the main plate on the main plate.
Engages with legs of multiple other stools stacked together
Provided is a stool characterized in that it is formed into a long groove having an effective and substantially constant groove width .

According to the above construction, since the plurality of legs extend downward from the lower surface of the main plate and incline toward the side, it is possible to prevent the legs from getting in the way when the stool is used. Further, the legs can be attached at any position on the lower surface of the main plate, which increases the degree of freedom in design. Furthermore, the outer edge of the main plate is formed with a plurality of notches that engage with the legs of another stool when a plurality of stools are stacked , and the notch formed in the main plate is
With several other stool legs stacked above the board
It is formed in the shape of a long groove that can be engaged and has a substantially constant groove width.
So that, when stacked a plurality of stool in three or more stages
The leg of the stool above the second step from the bottom
Can be engaged with notches formed in the main plates of the plurality of stools . Therefore, the legs and the main plate can be prevented from interfering with each other, and they can be stacked stably with good balance.

Moreover, since the legs are provided with stoppers that come into contact with the main plates of other stools when the stools are stacked, the pitch interval between the main plates at the time of stacking the stools is arbitrary according to the distance from the main plate to the stopper. Can be set to. Therefore, it is possible to secure stability when stacking stools regardless of the cross-sectional shape of the legs and to expand the degree of freedom regarding the degree of leg opening. It is possible to provide a stool that can stack stools without limitation.

Therefore, it is possible to provide a stool that can be stacked stably in good balance without deteriorating the feeling of use and the degree of freedom in design, and without limiting the number.

Preferably, the notches are respectively formed on the main plate just above the legs.

According to the above construction, the notch formed in the main plate can receive the leg of the stool stacked on it, and can also receive the leg of the stool stacked on it. It is possible to minimize the space between the main plates to be secured,
The stool storage efficiency can be further improved.

Preferably, the stopper comprises a frame connecting the legs.

According to the above construction, since the leg structure can be strengthened by the stopper, it is possible to provide a stool that is strong against a load from above.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings.

[0020]

FIG. 1 shows an embodiment in which the present invention is applied to a stool having three legs. In the figure, (a) is a left side view of the stool, (b) is a plan view thereof,
(C) is its front view, (d) is its bottom view, and (e) is 3
It is a front view showing the state where two stools were piled up.

Referring to FIG. 1, a stool 1 comprises a circular main plate 2, here three legs 3, 4, 5. The stool 1 can be used as a table or a chair, and the main plate 2 serves as a top plate when the stool 1 is used as a table and a seat portion when the stool 1 is used as a chair. Will play a role as. The material of the main plate 2 and the legs 3 to 5 is not particularly limited, and generally can be appropriately selected from structural materials such as wood, plastic, and steel.

A circular substrate 6 is fixed to the center of the lower surface of the main plate 2 with, for example, screws 7, and the upper ends of the legs 3 to 5 are fixed and integrated with the substrate 6. The legs 3 to 5 extend downward from the lower surface of the base plate 6 and at an angle more outward than the outer edge of the main plate 2, and are arranged at equal pitch intervals in the circumferential direction with respect to the main plate 2. There is. Since the outer dimension (diameter) of the substrate 6 is smaller than that of the main plate 2, the upper portions of the legs 3 to 5 attached to the main plate 2 via the substrate 6 do not protrude outward from the outer edge of the main plate 2. Therefore, even if the stool 1 is used as a chair, the legs 3 to 5 do not collide with the legs of the seated person. Further, the legs 3 to 5 can be attached at arbitrary positions on the lower surface of the main plate 2, so that the degree of freedom in design is increased.

The main plate 2 is formed with three notches 8 to 10 extending from its outer edge toward the center. Cutout 8
Numerals 10 to 10 are engaged with the legs 3 to 5 of the upper stool 1 when the two stools 1 are stacked, and are arranged and formed on the main plate 2 in the circumferential direction at the same pitch intervals as the legs 3 to 5. Has been done.

In this embodiment, the three legs 3 to 3 of the stool 1 to
5 can be engaged respectively with the three notches 8 to 10 formed in the main plate 2 of the stool 1 thereunder, so that another stool 1 can be stacked immediately above the stool 1. At the same time, it is possible to reliably prevent the stacked stools 1 from being laterally displaced with respect to the stools 1 below the stools 1 and losing or losing the center of gravity.

The notches 8 to 10 extend to the vicinity of the outer periphery of the substrate 6,
That is, it is desirable that the legs 3 to 5 extend long up to the vicinity of the upper roots. If the notches 8 to 10 are short, the space between the main plates 2 and 2 cannot be reduced when the stools 1 are stacked, which causes a decrease in the storage efficiency of the stools 1 due to the stacking, but the leg 3 to 5 When the stools 1 are extended to the vicinity of the base of the upper end, the stools 1 can be effectively stacked at a small pitch.

At a position separated from the lower surface of the main plate 2,
The legs 3 to 5 of the stool 1 are provided with stoppers 11 that regulate the pitch distance between the main plates 2 and 2 by contacting the main plates 2 of the other stools 1 when the stools 1 are stacked on the other stools 1. Is provided. Therefore, by setting the interval between the main plate 2 and the stopper 11 arbitrarily, the pitch interval between the main plates 2 and 2 at the time of stacking the stools can be set arbitrarily.

In this case, the distance between the main plates 2 and 2 is such that at least the legs 3 to 5 of the stool 1 are below the main plate 2 of the stool 1.
It is desirable to set the dimensions so as to prevent contact with the inner ends of the notches 8 to 10 formed in the above. If such a space is not secured by the stopper 11, the slanted legs 3 to 5 of the stool 1 are located below the stool 1.
By contacting the inner ends of the notches 8 to 10 formed in the main plate 2 of the above, it is supported at three points on the lower stool 1, and this is an extremely unstable holding form, so Although it is easy to lose the balance, in the present invention, the stopper 11 can secure an arbitrary space between the main plates 2 and 2 of the stool 1, so that the stool 1
Can be stably placed on the main plate 2 of the stool 1 thereunder via the stopper 11. Therefore, the stools 1 can be stacked stably with a good balance of the center of gravity.

Further, the notches 8 to 10 in this embodiment are the legs 3
It is formed on the main plate 2 so as to be located right above the above.
Therefore, as shown in FIG. 1E, when three or more stools 1 are stacked, the main plate 2 of the lower stool 1 is stacked.
The notches 8 to 10 formed in the above can receive the legs 3 to 5 of the stool 1 thereon, and further can also receive the legs 3 to 5 of the stool 1 thereabove, so that the stool 1 is You can stack as many stages as you like. If the notches 8 to 10 are formed to be displaced from the legs 3 to 5 in the circumferential direction of the main plate 2, the legs 3 to 5 of the stool 1 shown in FIG. Increase the space between the main plates 2 and 2 so that they do not interfere, or
It is necessary to take measures such as shortening ~ 5 or inclining the legs 3 to 5 to a more diverging angle, which may restrict the shape and size of the stool 1 or affect its usability. As shown in the example, if the notches 8 to 10 are located right above the legs 3 to 5, the stool 1 can be placed at a small pitch interval without restricting the shape and size of the stool 1 or affecting its usability. Will be able to stack effectively.

Further, in this embodiment, since the stopper 11 is composed of a frame for connecting the legs 3 to 5, more preferably a ring-shaped frame, the stopper 11 can structurally strengthen the legs 3 to 5. it can. Therefore, a leg structure that is particularly strong against a load from above can be obtained.
