  By the way, the conventional special seats are installed in a room that is mainly separated from the outside by glass or the like, so the conventional retractable chairs for the special seats can accommodate seats and armrests when not in use. However, in recent years, it has been considered to remove the partition of glass for special seats to enhance the sense of reality, and in such a case, the chair is protected against dust by selecting materials or processing the chair. The addition of the function and the drip-proof function has a great design restriction, and therefore it has been desired to develop a retractable chair that can be used outdoors without performing a dust-proof process or a drip-proof process.

  The present invention provides a retractable chair that can be used outdoors without performing dustproofing or dripproofing, with the dustproof function and dripproofing function enhanced by the shape of the chair during storage.

  That is, the stowable chair of the present invention is a seat back, a seat support portion provided on the right and left sides of the backrest, and a seating use position and an upright position positioned in front of the backrest. A seat portion supported by the seat portion supporting member so as to be swingable between the seating position, a use position that is positioned above the backrest portion, and is lifted up; And a pillow portion connected to the backrest portion so as to be swingable with respect to the forward-folded storage position covering the backrest portion. Note that when the chair and its parts are referred to as up / down, left / right, front / rear, etc., it means the direction seen from the person sitting forward on the chair.

  According to the retractable chair of the present invention, when a chair is used, a person can be seated by setting the seat portion to a substantially horizontal use position and the pillow portion to a substantially vertical use position. On the other hand, when the chair is not used, the backrest portion can be covered by raising the seat portion substantially vertically to the storage position and moving the pillow portion forward to the storage position. In other words, when the chair is not in use, the seat and the pillow are positioned in the storage position, so that the upper surface of the seat, the front of the backrest, and the front of the pillow are positioned inward to place the chair in the storage state. it can. Thus, when the chair is not in use, the chair is stored compactly, and the upper surface of the seat, the front of the backrest, and the pillow are the surfaces that the person touches when seated by the bottom of the seat and the back of the pillow. The front surface can be protected from dirt and rain. Therefore, it is possible to provide a storage chair that is easy to maintain, has excellent dust and drip-proof performance, can withstand outdoor use, and is comfortable to sit on. If you install it, you can sit down and watch the game with a sense of presence.

  Here, it is located above the seat and on the left and right sides of the backrest, and is supported by the seat support member so as to be swingable between the forward use position and the retracted storage position. If the armrest portion is further provided, and the pillow portion in the storage position covers the armrest portion in the storage position in cooperation with the seat support member, the armrest portion is substantially horizontal when seated. A chair that can be seated in a more relaxed state can be provided by moving forward to the use position. Further, when the chair is not used, the armrest portion can be raised to the storage position, and the armrest portion can be protected from dirt and dirt by covering the armrest portion with the pillow portion and the seat support member at the storage position.

  Moreover, if a fixing means for releasably fixing the pillow part at the use position is provided, the pillow part is securely fixed at the time of use, and the unintentional falling from the use position of the pillow part to the storage position (forward rotation) Can be prevented.

  Further, swinging between the use position and the storage position of the pillow part, and swinging between the use position and the storage position of at least one of the armrest part and the seat part, respectively, By providing an interlocking mechanism that interlocks so that the swinging to the use position and the swinging to the storage position correspond to each other, it is possible to reduce the work burden when using or storing the chair, and to swing when storing. It is possible to prevent forgetting to swing a part of the movable part to the storage position.

  Moreover, the pillow part has a seat cover so that the seat cover can be stored. The seat cover is exposed at the storage position of the pillow part, and the bottom surface of the seat part at the storage position is exposed to the seat cover. If the chair can be stored, the seat cover can cover the bottom surface of the seat in the storage position with the seat cover, thereby providing a retractable chair having higher dustproof and drip-proof performance in the stored state. Can do.

  Hereinafter, embodiments of a retractable chair according to the present invention will be described in detail with reference to the accompanying drawings. Here, FIGS. 1A and 1B are a front view and a side view showing a state in which each part is located at a use position in the first embodiment of the retractable chair according to the present invention, and FIG. (B) and (b) are a front view and a side view showing a state in which each part of the stowable chair of the first embodiment shown in FIG.

  The retractable chair 1 according to the first embodiment is, for example, a two-seat pair seat, and includes two backrest portions 3 and three seat support members 5 provided between the two backrest portions 3 and on the left and right side portions. And two seats 2 supported by the seat support member 5 so as to be positioned in front of the respective backrests 3, respectively, above the respective seats 2 and in front of and behind the respective backrests 3. Three armrests 4 supported by each seat support member 5 so as to be positioned, two pillows 6 arranged so as to be positioned above the two backrests 3, and fixing those pillows 6 The support plate 11 is fixed to a wall surface (not shown) with bolts (not shown), and the backrest portion 3 and the seat support member 5 are fixed. It has a back plate 7 connected at its lower end. When the chair and its respective parts are referred to as up / down, left / right, front / rear, etc., it means the direction seen from the person sitting forward on the chair.

  Here, the backrest portion 3 has a substantially hill-shaped vertical cross section, and the lower end portion and the back surface are inclined to the wall surface (not shown) and the back plate 7 so that the lower portion is located slightly forward from the upper portion and is inclined with respect to the vertical surface. Each of the backrests 3 is attached with bolts or the like (not shown). The backrest 3 is formed of, for example, a plywood core material and urethane between a substantially rectangular steel plate processed by baking with synthetic resin and a vinyl leather as an overlay. The back of the seated person (not shown) can be supported with a good cushion.

  The seat support member 5 is made of, for example, an aluminum die-cast plate having a substantially trapezoidal shape, which is combined with a triangular shape that is inclined so as to go backward toward the upper part of the quadrangular shape. And the back plate 7 with bolts or the like (not shown), and the seat 2 is swingably supported in front of the lower portion thereof, and the armrest 4 is swingably supported in front of the lower portion of the inclined portion. is doing. In addition, the inclined portion is formed so that the upper surface of the armrest portion 4 follows the inclined portion when the armrest portion 4 is flipped up and swung to the storage position as will be described later. The member 5 can accommodate the armrest portion 4 in a more compact manner. Further, in the stowed state of the chair, the seat support member 5 covers the backrest 3 and the side of the seat 2 located at the stowed position, so that the sides of the backrest 3 and the seat 2 are prevented from being soiled. It is possible to prevent dirt from entering the seat surface of the seat portion 2 from the side.

  The seat portion 2 has a substantially square cross section, and is formed, for example, by inserting urethane between a synthetic resin that has been blow-molded and a vinyl leather that is a top cover. The seat 2 is supported by the seat support member 5 so that it can swing between a substantially horizontal use position and a substantially vertical storage position by a shaft 8 supported by the seat support member 5. It is always urged toward the storage position by a well-known automatic seat upright mechanism 9, for example, a mechanism using a helical spring. Thereby, while being able to support a buttocks part of a seated person (not shown) with a good cushion, when the chair 1 is not in use, the seat part 2 can be automatically raised to the storage position. Furthermore, since the seat portion 2 covers a part of the front surface of the backrest portion 3 in the storage position, it is possible to prevent the front surface of the backrest portion 3 from becoming dirty when the chair 1 is not used.

  The armrest portion 4 has a streamline shape, for example, is formed of semi-rigid urethane having a steel plate inside. The armrest 4 is supported by a shaft 10 supported by the seat support member 5 so as to be able to swing between a substantially horizontal use position and a storage position slightly tilted backward from the vertical. Then, the inclined surface formed by the bottom surface of the armrest portion 4 that is bounced up to the storage position and contacts the inclined portion of the seat support member 5 is the inclination of the backrest portion 3 that is above the tip of the armrest portion 4 at the storage position. The armrest portion 4 and the seat portion supporting member 5 are configured so as to have substantially the same angle as the above. As a result, the armrest part 4 can be used by moving it to the use position only when necessary, and when not in use, the armrest part 4 can be moved up to the storage position so that it can be smoothly inclined from the upper part of the backrest part 3. The upper side of the chair 1 can be covered using a pillow portion 6 described later.

  The support plate 11 to which the two pillow portions 6 are fixed has a size capable of covering the upper sides of the two backrest portions 3 and the two seat portions 2 in the storage position. In shape, it is formed by packing a core material of plywood and urethane between a molded synthetic resin member and a vinyl leather that is an upper layer. Moreover, the shape of the pillow part 6 is formed in the shape which can cover the backrest part 3, the seat part supporting member 5, and the armrest part 4 exactly in a storage position. And the support plate 11 is connected with the back plate 7 and the hinge 12, and is connected via the seat support member 5 and the back plate 7, whereby the support plate 11 and the pillow portion 6 are connected to each other in FIG. The use position shown in a) and (b), which is flipped up substantially vertically, and the armrest part 4 and the seat part 2 in the storage position shown in FIGS. 2 (a) and 2 (b), and the backrest part. 3 and can be swung between a storage position covering 3. Further, the support plate 11 has a well-known fixing means such as a slide lock type lock button mechanism 15 using a cam so that the support plate 11 can be releasably fixed to the back plate 7 at the use position. 1 is used, the lock pin 16 is hooked by the lock button mechanism 15 to prevent the support plate 11 and the pillow portion 6 from rotating forward unintentionally, while ensuring the safety of a seated person (not shown). The head is supported by a good cushion, and when not in use, the support plate 11 and the pillow portion 6 cover the seat portion 2, the backrest portion 3 and the armrest portion 4 without gaps to prevent them from becoming dirty. it can. Small pads 17 are arranged on both outer sides of the two pillow parts 6, and each pad 17 is fixed to the support plate 11 and covers the upper end of the seat support member 5 at the storage position of the support plate 11. Has been. Therefore, it is possible to reliably prevent dirt from entering the seat surface of the seat 2 from the side in the stored state.

  Therefore, according to the retractable chair 1 of the first embodiment, as shown in FIG. 1, the seat 2, the armrest 4, and the pillow 6 can be seated when in use, and can be seated. In addition, as shown in FIG. 2, when the seat 2 is not in use, the seat 2, the armrest 4 and the pillow 6 are placed in the stowed position, so that the upper surface of the seat 2 and the armrest 4 are the surfaces that the seated person contacts when sitting. And the backrest part 3 and the front surface of the pillow part 6 can be stored facing inward. Therefore, when it is not in use, it can be stored compactly without exposing the surface that the occupant touches to the outside, so that the surrounding space can be secured. It is possible to provide a stowable chair that is easy to sit on and has a comfortable sitting surface.

  In addition to the present embodiment, the number of the seat part 2, the backrest part 3, the armrest part 4, and the pillow part 6 can be arbitrarily changed according to the number of people seated. Further, the backrest 3 and the pillow 6 may be directly connected by a hinge 12 or the like without using the back plate 7. If each armrest part 4 and the pillow part 6 are connected by, for example, interlocking means using a link mechanism or the like housed in the seat support member 5, the swing between the use position and the storage position of the pillow part 6 is achieved. And the swing between the use position and the storage position of each armrest portion 4 can be linked to reduce the work load during use and storage.

  FIGS. 3A and 3B are side views showing a state in which each part is located at the use position and a state in which each part is located at the storage position in the second embodiment of the stowable chair according to the present invention. The present embodiment is different from the first embodiment in that the pillow portion 6 can accommodate the seat cover 13 via the support plate 11, and is the same as the first embodiment in other points. It is configured.

  Here, the seat cover 13 is made of a substantially quadrangular synthetic resin plate that fits within the range of the support plate 11, and is attached to the upper portion of the support plate 11 with a hinge 14. When the chair 1 is used, it is stored between the support plate 11 and the back plate 7 to form a part of the back surface of the pillow portion 6, and when not in use, the hinge 14 is used from the pillow portion 6 in the storage position. By rotating forward, the bottom surface of the seat 2 can be covered.

  Thereby, the clearance gap which arises between the support plate 11 and the pillow part 6 of a storage position, and the seat part 2 of a storage position can be block | closed, and the storage type chair which can prevent the stain | pollution | contamination by dust or rain more reliably can be provided.

  In addition to this embodiment, the seat cover 13 is provided with, for example, a roll pipe with a built-in spring inside the pillow portion 6, and when the chair is not used, the seat cover is pulled out to cover the seat. You may store in a pillow part using systems, such as a roll screen. If such a winding-type seat cover is used, a seat cover that covers the entire seat can be provided regardless of the size of the seat 2 and the pillow 6.

  Thus, according to the retractable chair of the present invention, when the chair is used, a person can be seated by setting the seat portion to a substantially horizontal use position and the pillow portion to a substantially vertical use position. On the other hand, when the chair is not used, the backrest portion can be covered by raising the seat portion substantially vertically to the storage position and moving the pillow portion forward to the storage position. In other words, when the chair is not in use, the seat and the pillow are positioned in the storage position, so that the upper surface of the seat, the front of the backrest, and the front of the pillow are positioned inward to place the chair in the storage state. it can. Thus, when the chair is not in use, the chair is stored compactly, and the upper surface of the seat, the front of the backrest, and the pillow are the surfaces that the person touches when seated by the bottom of the seat and the back of the pillow. The front surface can be protected from dirt and rain. Therefore, it is possible to provide a storage chair that is easy to maintain, has excellent dust and drip-proof performance, can withstand outdoor use, and is comfortable to sit on. If you install it, you can sit down and watch the game with a sense of presence.
