Description of the Invention (Technical Field) The present invention relates to chairs. [Knowledge technology] Generally, the feet of an office chair or a study chair used together with a table have: a support portion, a support seat portion, and an upward and downward direction; and 5 legs, at the same length and at an equal angle Radially disposed below the support portion. The length of each foot 'is generally about 300 mm'. This size is the length generally used according to stability tests and other ergonomic viewpoints made by a given group. [Problems to be Solved by the Invention] However, when a chair having the above-mentioned feet is used in a half-open type table, etc., in order to fully store the chair inside, the width of the storage space may be insufficient. To solve this problem, simply shortening each leg will prevent the stability and the like mentioned above. Therefore, an object of the present invention is to provide a chair that can be fully stored in the interior even in a place with a relatively narrow storage space and has stability. [Means to solve the problem] In view of the above-mentioned object, in the first scope of the patent application, a chair is provided, which has a seat portion and a foot portion for people to sit, and is characterized in that the aforementioned foot portion has: from below The support part of the support seat and the radial setting of 3 nanometer paper size are applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) --------- I ------- (Please (Read the precautions on the back before filling this page.) INTRODUCTION 1223252 A7, __; _ B7_ 5. Description of the invention (1) 4 or more feet on the support; among them, there are at least 2 relatively short feet and at least 1 Relatively long feet. (Please read the precautions on the back before filling out this page.) When sitting on the seat, make sure that at least one of the opposite long legs is seated on the back side (rear side than the left and right direction) to ensure that the person sitting is the most restless. After the weak side stability. When accommodating, if the angle formed by the two most isolated feet in the middle of the angle of two short feet or more is stored in the direction of two equal parts, the shortness of the feet will improve the storage. In item 2 of the scope of patent application, the chair of item 1 of the scope of patent application is provided, in which the aforementioned leg portion has 5 feet, and the seat is distinguished from the front and rear marks. The circumferential position of the seat portion relative to the aforementioned leg portion is Fixed, at least two opposite short feet are located more forward than the left-right direction line of the chair, and two opposite long feet are located further rear than the left-right direction line. In addition to the simple symbols, the symbols in this manual also include the case of having a back or distinguishing the front and back by the shape of the seat. Since the direction of the seat is fixed to the foot, as long as you sit down obediently, you can sit in the correct direction. In this state, since the two long legs are positioned further behind than the left-right direction line, and the two short legs are positioned more forward than the left-right direction line, sufficient stability can be ensured on the rear side. In addition, when storing, if the angle formed by the two most isolated feet in the angle of two or more short feet is stored in a direction of two equal parts (the direction within the range of the front side when sitting), Shorter to improve storage. In item 3 of the scope of patent application, the chair of item 1 of the scope of patent application is provided, in which the aforementioned leg portion has 5 feet, and the seat is distinguished from the front and rear marks. The seat portion can rotate relative to the aforementioned foot and has a recovery Mechanism: 4.

Description of the invention (>) When it rotates at an appropriate angle, it can generate a force and move to a predetermined angle position In the state of the predetermined angular position, at least two relatively short feet are located more forward than the left-right direction line of the chair, and two relatively long feet are located more rearward than the aforementioned left-right direction line. Because the seat can rotate relative to the feet, even if the space on the front side of the chair is narrow, there is no need to move the chair to the rear. When the seat is about to sit down, or when the seated person wants to stand up, rotate the chair. The seat can sit or stand on the side that has been opened from the narrow space on the front side. In addition, when the angle is appropriately rotated, since the restoring mechanism is capable of generating a force and recovering in the direction of the predetermined angular position, the direction of the seat part automatically faces the predetermined angular position, and it does not take time to wait after standing up. Also, it is very convenient for those who will be sitting later to know the regular direction immediately. In the state of the predetermined angular position, at least two relatively short feet are located more forward than the left and right direction lines of the chair, and two relatively long feet are located more rearward than the aforementioned left and right direction lines. The same is true for 2 items. [Embodiments of the invention] Hereinafter, the present invention will be described in more detail with reference to the embodiment examples shown in the drawings. FIG. 1 is a perspective view of a chair according to a first embodiment of the present invention. FIG. 2 is a plan view of the leg 10, and FIG. 3 is a plan view of a cross section of the table.

Description of the invention (屮) Supporting part 12; 5 feet LI, L2, L3, L4, L5, which are arranged radially at this supporting part; and casters 10R, which are installed at the front end of each foot . In this example, the connection portion is connected to the support portion so that it cannot rotate. Referring to Fig. 2, each foot is arranged at an equal angle with the support as the center, and is arranged at 72-degree intervals. The length of each foot is the foot L1 which extends in the front direction A of the seat portion 12, and is the same length and length as the feet L3 and L4 behind the left and right direction lines SL. The other two legs L2 and L5 are only short. The given size is eight L and the length is LS. As a result, the maximum width W 'of the legs of the chair when the chair is inserted in the direction A can be set smaller than the width W of the space portion 20K of the semi-open table 20 shown in FIG. The width W of the space portion of the table in this example is formed to be narrower than the maximum width W '' of the legs when the legs L2 and L5 of the chair are not shortened. Therefore, by setting the short predetermined size AL, the chair can be fully inserted into the space portion. The above-mentioned half-open type table is merely an example, and other types of tables may be used. In this example, the length of the long side feet is 315mm, and the length of the short side is 230mm. That is, the predetermined length AL is 85 mm, and although the length LL is about 27% shorter, the width W of the apparent space portion can be as short as about 35% to ensure the stability of the chair. That is, the stability of the rear side is stabilized by the feet L3 and L4 having a predetermined length, and the front side is supported by a human foot. Even if the length of the feet L2 and L5 is shorter than the predetermined size, there is no problem in stability. . In addition, even if the feet L1 and L2 are shortened in the same manner, since the front side is supported by the human foot, a large problem of stability is not easily caused. The above foot sizes are examples, and of course other sizes are possible.

Description of the invention (5) If the side of the 10R protrudes to the right or left than the front ends of the feet L2 and L5, as shown in Figure 2, the width including the side of these casters is W '. In addition, the feet may not be arranged at equal angles, as long as the two feet L3 and L4 are located behind the left-right direction line SL, and the remaining three feet are located on the front side. In addition, even if the leg portion 10 is the same as that shown in FIG. 2, and only the front and rear portions of the seat portion are opposite to the first configuration example of FIG. 1, it is also within the scope of the first patent area of the present application. That is, the back portion 12B is disposed opposite to the front-rear position with respect to the seat portion 12Z, and the direction B in FIG. 2 becomes the front side. In this case, the long feet L1 are located on the rear side, and the long feet L3 and L4 are located on the front side. The other two chairs having short legs L2 and L5 and having a width W 'smaller than the width W of the space portion of the table are the same as those in the first embodiment. In the above, although the number of feet is five, it is sufficient if there are four or more. The relationship between the feet and the space 20K at the time of four is schematically shown in FIG. 4 (the width W ′ in this figure does not mean that the feet are the largest. width). The front two feet LI and L4 are short feet, and the rear two feet L2 and L3 are long feet. In this case, although the chair may not be able to completely store each foot in the space portion 20K shown by the rectangular two-point chain line, it is considered that there is no problem in practical use because most of it can be stored. Regarding the stability, the rear side is stable due to the existence of two long feet. Although the front side only has two short feet, it is not easy to cause problems when the chair is used to support it with the feet of the seated person. . In addition, the feet can have more than 6 sticks. Referring to Fig. 5, another embodiment will be described, and the connection structure between the seat portion 12 and the leg portion 10 in the first embodiment is changed. That is, the shaft portion 12S '(projecting downward from the lower end surface of the connecting portion 12S) is inserted into the bearing hole of the support portion 10S to be able to rotate 7 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ( Please read the precautions on the back before filling in this page) Order ·· 1222352 B7 V. Description of the invention (G) (Please read the precautions on the back before filling in this page) Move to form the lower end of the connecting portion 12F and the support portion 10S The end surface 10F is inclined (recovery mechanism), and these surfaces are configured to be in contact with each other. Therefore, when sitting in the sitting part, the face 12F and face 10F push each other, making the connecting part 12S difficult to rotate. However, if a person stands up, the pushing pressure on the face becomes smaller, and the feet The portion 10 can rotate the seat portion 12 with a light force. That is, the seat portion 12 rotates while rising in accordance with the inclination angle of the aforementioned surface. However, for example, if you release your hand after turning it by 90 degrees, each surface is inclined, so you want to return to the original normal angular position (front) by the effect of gravity. If the friction is small, you will automatically return to the state of Figure 5. Normally, the seat of the chair is in the normal direction, so there is no need for the person who wants to sit to confirm the direction of the seat one by one each time. Sitting directly becomes a stable direction. -Line · It is different from the above. If the seat 12 is rotated, it can be restored to the normal angular position by spring force. For example, one end of a torsion spring (not shown) may be installed at an appropriate position (for example, a connection part) of the leg part 10, and the other end may be installed at an appropriate position (for example, a support part) of the seat part 12. As mentioned above, although gravity can be used, if other forced recovery mechanisms are provided, for example, when a person wants to stand up from a chair facing the table, he can rotate the seat by about 90 degrees to easily stand in the direction without obstacles. Get up, even if you keep it in this state, because the seat will automatically return to the regular direction, and you often know the stable direction of the chair, so it is very convenient. The mechanism for automatically restoring the rotation of the seat to the normal direction as described above can also be applied to other than the first embodiment. The recovery mechanism using the spring as described above may be used together with the mechanism of the inclined surface in Fig. 5 or may be used alone. In the above description, the back portion 12B is provided on the seat portion 12 so that the paper size can be adjusted according to the Chinese National Standard (CNS) A4 (210 X 297 mm) 1222352 A7 · _____B7___ — _ 5.
