Description

  The present invention relates to a seat-up type chair provided with a seat part that can be raised from a lying posture when a user is seated to a standing posture when not seated.

  For example, in theaters, movie theaters, stadiums, etc., many chairs are arranged in the front, rear, left, and right directions, so in order to secure a moving space, etc., when the seat is not seated from the lying position when the user is seated The chair-up type chair that can be raised up to the standing position is widely adopted. By using this seat-up type chair, a sufficient space between the chairs in the front and rear rows can be secured.

  Usually, in this type of seat-up type chair, in order to ensure the mobility of the seat portion, the seat portion and the back portion are configured separately and a gap is formed between them. This gap is further enlarged, especially when the seat is raised up, and when the user places a personal belonging such as a pamphlet or a mobile phone on the seat surface, the gap falls from the gap and moves below the seat. There is a possibility that the seated person may forget without knowing it.

  Therefore, in Patent Document 1, in order to prevent a load from falling from a gap between the seat and the back, a bag-like load fall prevention extending between the seat and the back at the back of the gap is disclosed. The structure which provides a member and hold | maintains a fallen object with this luggage | load fall prevention member is disclosed.

JP-A-11-225844

  In the case of the configuration of the above-mentioned Patent Document 1, although the load can be prevented from falling on the floor surface between the seat and the back by the load fall prevention member, the held load is difficult to visually recognize from the outside. In the state in which the bag is raised, the luggage held by the seat portion is hidden, and the seated person may not notice that the luggage is held by the luggage fall prevention member, which may cause forgotten items.

  The present invention has been made in consideration of the above-described problems of the prior art, and can allow a user to recognize a fallen object even when a load or the like falls from between the seat and the back. An object is to provide a flip-up chair.

  The seat-up type chair according to the present invention is a seat-up type chair provided with a back part and a seat part that can be raised from a lying position when seated to a standing position when not seated. And a member having an inclined surface with the front side lowered.

  According to such a configuration, for example, when a seated person stands up, after placing a load such as a mobile phone or a pamphlet on the seat surface of the seat in a lying position, the seat jumps up and takes a standing posture. Even if the baggage has fallen from the seating surface to the lower part of the seating part through the back and the seating part, will it slide out on the inclined surface and return to the vicinity of the seated person's feet? Or, it abuts on the inclined surface and stays on the seating surface. This prevents the dropped luggage from being hidden under the seat, so that the user can easily recognize the luggage. Further, since the load that has fallen and slipped on the inclined surface is expelled not near the seat portion but near the user's feet, it is easy to pick up the load.

  The back portion is supported by a pair of left and right leg portions, and the member having the inclined surface is provided between the left and right leg portions so that the member having the inclined surface can be easily formed at a lower position between the back portion and the seat portion. Can be installed.

  The member having the inclined surface is a plate-like member, and when a space is formed between the floor surface on which the flip-up chair is installed and the lower surface of the inclined surface, for example, the front seat and the rear seat The feet of the seat can be appropriately partitioned, and the seated person in the rear seat can extend his / her feet to the space below the front seat with ease, making seating easier. In addition, luggage such as bags can be placed in this space.

  The member having the inclined surface has a rear end that extends upward along the back surface of the back portion to form a cover portion that covers at least a part of the back surface, so that the feet of the seated person in the back seat (shoes) It is possible to prevent dirt and food and beverages from adhering to the back fabric of the front seat, and cleaning becomes easy.

  The member having the inclined surface is formed such that the inclined surface below the seat portion and the cover portion on the back surface of the back portion are formed continuously, and is curved at a connecting portion between the inclined surface and the cover portion. When the surface is provided, it is possible to prevent the luggage that has fallen from above the seat surface to below the seat portion through the space between the back portion and the seat portion, and to be smoothly discharged from the inclined surface.

  According to the present invention, in the seat-up type chair, it is provided with a member having an inclined surface whose front side is lowered below the back portion and the seat portion, so that, for example, when a seated person stands up, a lying posture After placing a load such as a mobile phone or pamphlet on the seat in the seat, the seat sits from the seat through the back and seat even if the seat jumps up and stands upright. The luggage that has fallen below the section slides on the inclined surface and is pushed forward and returns to the vicinity of the seated person's feet, or comes into contact with the inclined surface and stays on the seat surface. This prevents the dropped luggage from being hidden under the seat, so that the user can easily recognize the luggage.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a flip-up chair according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a flip-up chair 10 (hereinafter also simply referred to as “chair 10”) according to an embodiment of the present invention. In a theater, a movie theater, a stadium, etc., a plurality of chairs 10 are arranged in the left-right direction. The arrangement is shown. FIG. 2 is a side view of the chair 10 shown in FIG. 1, illustrating a predetermined front seat 10F and a rear seat 10R installed in the front and rear rows, and the front seat 10F is shown in a side sectional view.

  As shown in FIGS. 1 and 2, the chair 10 (the front seat 10F and the rear seat 10R) is a seat portion 14 for a user to sit on, and a back portion on which a seated person on the seat portion 14 leans back. (Backrest) 16 and a pair of left and right armrests 20 and 20 for a seated person to put his elbows on, and a plurality of chairs 10 arranged in the left and right direction are floor surfaces by a pair of left and right legs 22 and 22. It is fixed integrally on the top. A sliding member (sliding base, inclined member, receiving member) 24 having an inclined surface 24 a that is provided between the left and right leg portions 22 and that is lowered on the front side is disposed below the seat portion 14.

  The seat portion 14 is movable and extends from the side portion (side surface) on the base end side in the left-right direction and is rotated by a rotation shaft 25 supported by the leg portion 22 (armrest portion 20). Constructed in the body. The seat 14 is in a standing position, which is a non-use position when not seated, from a recumbent posture (see the seat 14 indicated by a two-dot chain line in the front seat 10F in FIG. 2) when the user is seated. (Refer to the seat portion 14 indicated by a solid line in the front seat 10F in FIG. 2). The seat portion 14 is elastically urged toward the standing posture in the rotation direction by, for example, an urging means (elastic member) (not shown).

  As described above, since the seat portion 14 is flip-up type (rotating type), the seat portion 14 is in a lying position, a standing posture, a lying posture, and a standing position between the back surface of the seat portion 14 and the front surface of the back portion 16. A gap G extending downward from the seat portion 14 is generated in any one or more of the intermediate postures (post-rotation postures).

  Although the armrest part 20 is installed in the outer side part of the chair 10, between the adjacent chairs 10 one piece used for both seats is installed in the intermediate part. In a similar manner, the leg portion 22 is installed on the outer side of the chair 10, but between the adjacent chairs 10, one common to both seats is installed in the middle portion.

  The back portion 16 has a structure in which a cushion material or the like (not shown) is provided around a frame or back plate (not shown) formed of plywood, a pipe, a wooden frame, etc., and this is covered with a tension fabric 26. In the case of the present embodiment, the upholstery 26 is stretched over substantially the entire surface excluding the lower half of the back surface 16 a of the back portion 16. In addition, the front surface of the back portion 16 against which the seated person hits has a curved surface shape whose center is recessed in the width direction. Due to the curved surface shape of the front surface of the back portion 16, especially when the seat portion 14 is in an upright posture, the gap G between the two is further expanded.

  On the upper surface (upper end) of the back portion 16 provided with the upholstery 26, a top plate (headwood) 28 covering the substantially entire surface is attached on the upholstery 26 covering the upper surface. For example, when the upper surface of the back portion 16 is used as a handrail or a handle, the top plate 28 serves as a surface that is manually contacted to prevent soiling of the upholstery 26 and facilitate cleaning. Furthermore, since the top plate 28 provides appropriate rigidity to the upper surface of the back portion 16 covered with the flexible upholstery 26, stability as a handrail or a handle is improved.

  FIG. 3 is a configuration diagram of the chair 10 in a state in which the seat portion 14 is in the standing posture, FIG. 3A is a partially omitted front view of the chair 10, and FIG. FIG.

  As shown in FIGS. 1 to 3, the sliding member 24 includes an inclined surface (inclined surface portion) 24 a disposed below the seat portion 14 and the back portion 16, and a back surface of the back portion 16 formed continuously behind the inclined surface 24 a. The plate portion 24b extends upward along 16a and covers at least a part (lower half) of the back surface 16a, and is, for example, a plate-like member made of a metal material or a resin material. It should be noted that a cloth such as a canvas may be stretched at least on the inclined surface 24 a of the sliding member 24. If it does so, the impact sound at the time of the fallen object (luggage 34) mentioned later hits the said sliding member 24 can be suppressed.

  The sliding member 24 has a bent shape in which an inclined surface 24a and a cover portion 24b are formed in a generally U shape (boomerang shape) in a side view through a curved surface 24c in the middle thereof. The curved surface 24c is a connecting portion between the inclined surface 24a and the cover portion 24b, and at least an inner surface (front surface or upper surface) on the side of the seat portion 14 is a curved surface having an arc shape (curved shape) (FIG. 2). reference).

  The inclined surface 24a extends to the curved surface 24c while inclining upward in the rearward direction with the front end (lower end) 30 being substantially in contact with the floor surface, It is located below the gap G formed between the front surface of the back portion 16 and faces the gap G. In other words, the inclined surface 24a is a position that closes the gap G between the seat portion 14 and the back portion 16 in a state where the seat portion 14 is in the lying posture, the standing posture, and the intermediate posture in the plan view of the chair 10. It is the surface which inclines in the front downward toward the direction from the base end side (rotation axis | shaft 25 side) of the seat part 14 in the state of lying down to the front end side. Although the inclination angle of the inclined surface 24a is not particularly limited, for example, it may be set within an angle range of about 30 ° to 80 ° with respect to the floor surface. Moreover, that the front end 30 is substantially in contact with the floor surface is a concept including, for example, a state in which the front end 30 is close to the floor surface within a few mm to 20 mm and a state in which the front end 30 is in complete contact.

  Since the sliding member 24 is constituted by a plate-like member as described above, a space S1 having a triangular shape in side view that gradually increases toward the rear is formed between the lower surface of the inclined surface 24a and the floor surface. (See FIG. 2). Although depending on the shape of the armrest part 20 and the leg part 22, the space S <b> 1 is closed by the floor surface below, the front is closed by the inclined surface 24 a (sliding member 24), and the left and right sides of the space S <b> 1 are armrest parts 20. Or since it is closed by the leg part 22, it becomes the pocket-shaped concave space which only the back opened substantially.

  The cover portion 24b stands upward from the inclined surface 24a via the curved surface 24c. The cover portion 24b has a rear end 32 fixed to the back surface 16a in a state where the rear end (upper end) 32 is set at a height position that covers a part (lower part or lower half) of the back surface 16a of the back portion 16. The side portions are respectively fixed to the left and right leg portions 22 (or the back surface of the armrest portion 20), thereby covering the lower half of the back surface side of the chair 10 (see FIGS. 2 and 3B). In other words, in the sliding member 24, the side portions of the inclined surface 24a and the curved surface 24c are fixed to the inner surfaces of the leg portion 22 and the armrest portion 20, and the cover portion 24b is fixed to the back portion 16 and the leg portion 22 or the armrest portion 20. Thereby, it attaches with sufficient intensity | strength with respect to the chair 10, and it covers the lower half part of the back side.

  As described above, in the chair 10 according to the present embodiment, the inclined surface 24a with the front side lowered is provided below the back portion 16 and the seat portion 14, that is, below the gap G formed between the two. A sliding member 24 is provided. Therefore, for example, when a seated person stands up, after the luggage 34 (for example, a mobile phone or a pamphlet (not shown)) is placed on the seat surface of the seat 16 in a lying position, the seat 14 jumps up and takes a standing posture. Even in such a case, the luggage 34 that has fallen from the seat surface downward through the space between the back portion 16 and the seat portion 14 (gap G) is slid forward on the inclined surface 24a to the front of the seated person. It returns to the vicinity of the foot (see arrows in FIGS. 1 and 2). As a result, the luggage 34 that is a fallen object is prevented from being hidden under the seat portion 14 and jumping out to the rear seat 10R side, so that the user can easily recognize the luggage 34, You can stop being left behind. Furthermore, since the dropped luggage 34 is ejected not near the seat portion 14 but in the vicinity of the user's feet, it is easy to pick up the luggage 34.

  Further, since the sliding member 24 is provided between the left and right leg portions 20, the sliding member 24 is positioned below the back portion 16 and the seat portion 14 so that the gap G can be reliably closed. The sliding member 24 can be easily installed.

  The sliding member 24 is a plate-like member, and a space S1 is formed between the floor surface on which the chair 10 is installed and the lower surface of the inclined surface 24a, so that the feet of the front seat 10F and the rear seat 10R can be appropriately positioned. It is possible to partition the seat, and the seated person in the rear seat 10R can extend his / her feet to the lower part of the front seat 10F (space S1) with peace of mind. In addition, luggage 36 such as a bag (indicated by a two-dot chain line in FIG. 2) or the like can be placed in the space S1.

  The sliding member 24 forms a cover portion 24c whose rear end 32 extends upward along the back surface 16a of the back portion 16 and covers (closes) at least a part (for example, the lower half) of the back surface 16a. . As a result, dirt on the feet (shoes) of the seated person in the rear seat 10R and dirt on food and drink can be prevented from adhering to the upholstery (backing material) 26 on the back surface 16a of the front seat 10F, and cleaning is easy. Become. Moreover, as shown in FIGS. 2 and 3B, since the lower half of the back surface 16a is covered by the cover portion 24b, the end portion of the tension fabric 26 stretched on the back surface 16a is placed inside the cover portion 24b. The finishing process at the time of the assembly can be simplified, and the production efficiency of the chair 10 is improved.

  The sliding member 24 is formed by continuously forming an inclined surface 24a below the seat portion 14 and a cover portion 24b on the back surface 16a of the back portion 16, and is curved at a connecting portion between the inclined surface 24a and the cover portion 24b. A surface 24c is provided. If the connecting portion between the inclined surface 24a and the cover portion 24b is sharply bent at a predetermined angle, the load 34 that is a fallen object from the gap G is caught in the bent portion, and the inclined surface 24a It may not be ejected smoothly. Therefore, by providing the curved surface 24c at the connecting portion, the luggage 34 (such as a corner of the pamphlet) is prevented from being caught and a smoother discharge property is secured.

  By the way, such a sliding member 24 can also be used for purposes other than simply ejecting the load 34 falling from the seating surface 16 through the gap G forward.

  For example, as shown in FIG. 4, the flip-up angle of the seat portion 16 is appropriately adjusted so that the seat surface of the seat portion 16 and the inclined surface 24 a of the sliding member 24 are at right angles (or substantially at right angles). Then, as shown in FIG. 4A, when a relatively hard booklet (pamphlet) P1 is placed on the seat surface as the load 34, the booklet P1 is stopped by the tip of the booklet P1 being caught by the sliding member 24. For example, the booklet P1 can be temporarily placed at the time of leaving. On the other hand, as shown in FIG. 4B, when a thin and flaky paper P2 is placed on the seat as the luggage 34, the paper P2 slides down without being caught by the sliding member 24, and the front of the chair 10 You will be knocked out. That is, the sliding member 24 can also function as a receiving member (stopping member) for the load 34 by adjusting the flip-up angle of the seat portion 16.

  Further, for example, as shown in FIG. 5, the seat surface of the seat portion 16 is adjusted by appropriately adjusting the flip-up angle of the seat portion 16 and using a sliding member 49 having a gentle inclined surface 49 a instead of the sliding member 24. Is set to be substantially vertical, and the inclined surface 49a of the sliding member 49 is inclined so as to approach the horizontal. As a result, the rear surface of the seat portion 16 (the lower surface in the flip-up state in FIG. 5) and the inclined surface 49a of the sliding member 49 become nearly horizontal and the gap between the two expands. Even a hard booklet P1 or the like can be easily slid down and pushed forward.

  As described above, the shape and installation angle of the sliding member 24 (49) and the angle of the seating surface of the seating portion 16 in the raised state are appropriately adjusted, that is, the extension line of the seating surface of the seating portion 16 in the standing posture. By making it possible to adjust the crossing angle between the slant surface 24a (49a) and the slant surface 24a (49a), it is possible to control whether it slides down or stays on the seat surface without slipping off according to the type or shape of the luggage 34. it can. Therefore, for example, by appropriately setting the angle when the seat portion 16 jumps up and the angle of the sliding member 24 according to the request of the user of the delivery destination of the chair 10, the control of the fall of the luggage 34 can be performed. 10 can be optimized for use in a theater or the like where 10 is installed.

  6 is a side view of a seat-up chair 50 (hereinafter also simply referred to as “chair 50”) according to a modification of the seat-up chair 10 shown in FIG. 50F and rear seat 50R are illustrated.

  The chair 50 according to this modified example has substantially the same configuration as the chair 10 except that the sliding member 52 (49) provided in the chair 10 shown in FIGS. 1 to 5 includes a sliding member 52 having a slightly different configuration. It is. For this reason, in the following description, the same referential mark is attached | subjected to the element which show | plays the same or similar function and effect as the chair 10 shown in FIGS. 1-5, and detailed description is abbreviate | omitted.

  As shown in FIG. 6, the front end (lower end) 54 of the sliding member 52 of the chair 50 is installed above the floor surface by a predetermined distance, so that the inclined surface 24c is formed between the left and right legs 20. A space S2 that communicates the foot space on the front seat 50F side and the rear seat 50R side is formed below.

  Thus, in the chair 50, the front end 54 of the sliding member 52 is installed at a sufficiently high position (for example, about 100 mm to 200 mm) from the floor surface, and the formation space S2 is formed below the front end 54. Since the foot space on the front seat 50F side and the rear seat 50R side communicates with each other through the space S2, a cleaner or mop (not shown) can be easily inserted below the seat portion 14, and the floor surface can be easily cleaned. There is an advantage that can be done.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.

  For example, the sliding members 24, 49, 52 of the chairs 10, 50 according to the above embodiment have exemplified the configuration in which the cover portion 24 b is provided via the curved surface 24 c behind the inclined surface 24 a. The cover part 24b may be omitted. Needless to say, the mounting structure of the sliding members 24, 49, and 52 can be changed as appropriate.
