Description

  The present invention includes a leg portion standing on a floor surface, a seat surface portion supported by an upper end side of the leg portion and seated by a user, and an elastic member interposed between the leg portion and the seat surface portion. It is related with the chair provided with at least.

  Conventionally, as this type of chair, there is known an invention in which the chair is a swing-and-hold type chair fixed to the floor surface, and the seating portion swings forward when not in use (see, for example, Patent Document 1). ). Specifically, since the seating portion can be tilted forward by the non-parallel four-bar link when not in use, there is an advantage that the rear is wide and the passage is easy to use.

  Further, there is also known an open leg type portable chair / cane having both functions of a cane and a portable portable chair, in which a leg portion of the chair is opened with one touch (see, for example, Patent Document 2). ). Specifically, when used as a chair, in a combined cane composed of a cane body part that becomes a leg and a grip part that becomes a seat part, the force of a spring acts on a pull-out bar provided on the leg part to push out the leg. Thus, the leg portion of the chair is opened with one touch.

  However, in the swing-and-retractable chair described in Patent Document 1 described above, a passage can be secured behind the seat when not in use. However, when applied to a chair in a game hall, for example, the distance between players In a narrow environment, there is a feature that it is difficult to go around from the rear to the front when sitting, because there is a feature that it sits after turning around from the left or right rear.

  In addition, according to the above-described open leg type portable chair / cane described in Patent Document 2, the leg of the chair leg is opened using the force of the spring. There was a big problem that the operation force was not good because it was necessary to apply a large force to resist the urging force.

  The present invention has been made paying attention to the problems of the conventional technology as described above, and the user sitting on the adjacent chair and the chair itself do not get in the way when sitting on the chair. Since it is easy to go from the back to the front, it is easy to sit down, and when sitting, it becomes easy to sit due to the weight of the user itself, and when leaving the seat, it will self-return to a state where it is easy to sit when not in use, The object is to provide a very convenient chair that can be seated or stored without human intervention.

The gist of the present invention for achieving the above-described object resides in the following items.
[1] A leg (11) standing on the floor, a seat surface (20) supported by the upper end of the leg (11) and seated by a user, the leg (11) and the seat And at least an elastic member (30) interposed between the surface portion (20) and
The seat surface portion (20) is held in an inclined state by the urging force of the elastic member (30) when not in use,
The inclined seat surface portion (20) is displaced in a substantially horizontal state against the urging force of the elastic member (30) due to the weight of the user when the user is seated,
The seat portion (20) in the substantially horizontal state is self-returned to a tilted state when not in use again by the urging force of the elastic member (30) when the user leaves the seat. Chair (10).

[2] A leg (11) standing on the floor, a seat surface (20) supported by the upper end of the leg (11) and seated by the user, the leg (11) and the seat And at least an elastic member (30) interposed between the surface portion (20) and
The seat surface portion (20) is composed of a pair of one-side seat surface portions (21a, 21b) divided into left and right,
Each of the one-side seating surface portions (21a, 21b) is inclined to the upper end side of the leg portion (11) via the movable column (23), respectively, and is in a state of being substantially horizontally aligned on the left and right sides. Supported to be swingable,
The elastic member (30) is connected to the one-side seat surface portions (21a, 21b) and the upper end side of the leg portion (11), and biases the one-side seat surface portions (21a, 21b) in an inclined state. And
When the seat surface portion (20) is not used, the one-side seat surface portions (21a, 21b) are held in the inclined state by the urging force of the elastic member (30),
The seat surface portion (20) in the inclined state is substantially resistant to the urging force of the elastic member (30) by the weight of the user when the user is seated on each one-side seat surface portion (21a, 21b) during use. Swings horizontally,
The seat surface portion (20) in a substantially horizontal state is self-returned to an inclined state when not in use again by the urging force of the elastic member (30) when the user leaves the seat. Chair (10).

The present invention operates as follows.
According to the chair (10) described in [1], the seat surface portion (20) supported on the upper end side of the leg portion (11) is inclined by the biasing force of the elastic member (30) when not in use. Retained. In this inclined state, the area that extends in the substantially horizontal direction is reduced by the amount by which the seat surface portion (20) is inclined. Thus, for example, when a plurality of game machines are installed in front of the gaming machine island (1) in a game hall, when sitting on the chair (10), the player and the chair (10 ) Does not get in the way, and it is easy to go from the back to the front, so you can sit down easily.

  When the user sits down, the seat surface portion (20) in the inclined state is displaced to a substantially horizontal state against the urging force of the elastic member (30) due to the weight of the user, and the user performs a special operation. It becomes the form which can be seated without. Furthermore, when the user leaves the seat surface portion (20) in a substantially horizontal state, the seat surface portion (20) is self-returned to the inclined state when not in use again by the urging force of the elastic member (30). In this way, when sitting, it becomes easy to sit due to the weight of the user itself, and when leaving the seat, it automatically returns to a state where it is easy to sit when not in use, so it can be seated or stored without bothering human hands is there.

  Specifically, for example, like the chair (10) described in [2], the seat surface portion (20) is formed by combining a pair of one-side seat surface portions (21a, 21b) divided into left and right, and each one side The seating surface portions (21a, 21b) can swing in a state of being inclined downward on both the left and right sides and on a substantially horizontal state aligned on the left and right sides, respectively, on the upper end side of the leg portion (11) via the movable column (23). Supported by Each one-side seat surface portion (21a, 21b) and the upper end side of the leg portion (11) are connected by an elastic member (30), and each one-side seat surface portion (21a, 21b) is connected by the elastic member (30). Is biased to an inclined state.

  Here, when each one-side seating surface portion (21a, 21b) is held in a state in which one end sides facing left and right are close to each other and the other end sides of the left and right are inclined downward on both sides, the area that expands in both side directions is particularly large. For example, even if a plurality of chairs (10) are installed side by side, the space between the chairs (10) when not in use can be widened, so that the user can easily go around from the rear to the front when seated.

  On the other hand, when the user is seated from one end side that protrudes upward and faces each other when the one-side seat surface portions (21a, 21b) are inclined, the one-side seat surface portions (21a, 21b) are weighted as they are. Thus, the elastic member (30) is swung to the left and right in a substantially horizontal state against the urging force of the elastic member (30) and held in the substantially horizontal state. Further, when the user leaves the seat, each one-side seating surface portion (21a, 21b) self-resets again to the original tilted state by the urging force of the elastic member (30).

  According to the chair according to the present invention, the seat surface portion when not in use is fixed in a state where the seat surface has an inclination, so when sitting on the seat surface portion in the inclined state, the seat surface seats on the adjacent chair. The user and the chair are not obstructed and can easily go around from the rear to the front, so that the user can sit down easily. In addition, when seated, the seat surface portion that has been inclined becomes easy to sit almost horizontally due to the weight of the user, and when leaving the seat, the seat surface portion is inclined when not in use by the biasing force of the elastic member. Since it is self-returning, it can be seated or stored without human intervention, which is very convenient.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments representing the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the chair 10 includes a leg portion 11 standing on a floor surface, a seat surface portion 20 supported by an upper end side of the leg portion 11 and seated by a user, the leg portion 11 and the seat. It comprises at least an elastic member 30 interposed between the surface portion 20. Hereinafter, a case where a plurality of gaming chairs installed side by side in front of the gaming machine island 1 in a game hall will be described as an example.

  As shown in FIG. 3, the gaming machine island 1 is constructed by alternately arranging a plurality of gaming machines 2 and ball lending machines 3 that are pachinko machines. On the floor in front of the gaming machine island 1, chairs 10 are arranged so as to be lined up at equal intervals on the left and right in correspondence with each gaming machine 2. As shown in FIG. 1, the leg portion 11 of the chair 10 is erected in a vertical state on a floor surface via a pedestal 12. On the upper end side of the leg portion 11, a spring support body 13 for connecting the elastic member 30 and a base portion 14 for supporting the seating surface portion 20 thereabove are provided.

  The seat surface portion 20 is composed of a pair of one-side seat surface portions 21a and 21b divided into left and right. Each of the one-side seating surface portions 21a and 21b is configured, for example, by covering a frame on the bottom surface side with a cushion or the like. Each of the one-side seating surface portions 21a and 21b has a rectangular shape or semicircular shape facing each other. At this time, it is provided in a size and shape that the user can easily sit on.

  A seating surface support 22 is provided on each of the back surfaces of the one-side seating surface portions 21a and 21b facing each other. Each seating surface support 22 is in a state in which each one-side seating surface portion 21a, 21b is inclined downward on both the left and right sides on the base portion 14 of the leg portion 11 via the movable column 23, and each one-side seating surface portion 21a, 21b is left-right. Are supported so as to be able to swing in a substantially horizontal state.

  More specifically, each movable column 23 has a lower end portion which is substantially perpendicular to the base portion 14 between a position where it rises substantially vertically as shown in FIG. 1 and a position inclined about 45 degrees laterally as shown in FIG. It is connected so as to be able to swing in the left-right direction so as to approach or separate. In addition, the seat support 22 is connected to the upper end of each movable column 23 so as to be swingable in the left-right direction so that the seat support 22 can be locked at a position inclined about 45 degrees to the left and right with the central axis in between. Yes.

  The elastic member 30 is composed of a pair of coil springs, one end of which is connected to both ends of the spring support 13 on the upper end side of the leg portion 11, and the other end is spaced apart from each other on the one side seat surface portions 21a and 21b. It is connected to the back of both sides. The elastic member 30 is biased so that the one-side seating surface portions 21a and 21b are inclined downward on the left and right sides.

Next, the operation of the chair 10 according to the present embodiment will be described.
As shown in FIG. 1, when the seat surface portion 20 is not used, the one-side seat surface portions 21 a and 21 b are respectively connected to the spring support body 13 with the respective seat surface support bodies 22 as fulcrums. Is pulled toward the spring support 13 (in the direction of the arrow in FIG. 1). As a result, each movable column 23 supporting each one-side seat surface portion 21a, 21b rises substantially in parallel with each other, and each seat surface support 22 connected to the upper end of each movable column 23 serves as a fulcrum. The surface portions 21a and 21b are held in a state of being inclined symmetrically about 45 degrees from the vertical direction downward to the left and right sides.

  In this way, when the one-side seating surface portions 21a and 21b are held in a state where one end sides facing left and right are close to each other and the left and right other end sides are inclined downward on both sides, the area that expands in both sides is particularly small. Become. Therefore, as shown in FIG. 3, even if a plurality of chairs 10 are installed in front of the gaming machine island 1 in the game hall, the spacing between the unused chairs 10 (W1 <W2 <W3 in FIG. 3) is maintained. The player and the chair 10 seated in the adjacent chairs 10 do not get in the way, and when sitting, it is easy to go around from the rear to the front, so that they can easily sit.

  When each one-side seating surface portion 21a, 21b is inclined downward on both the left and right sides, the user is seated from one end side that protrudes upward and faces each other. In FIG. 2, due to the weight of the user (player), the opposite one end sides of the one-side seating surface portions 21 a and 21 b support the upper and lower connecting portions of the movable columns 23 against the urging force of the elastic member 30. Is pushed downward (in the direction of the arrow in FIG. 2).

  Then, each movable column 23 connected to the base portion 14 and each seating surface support 22 is fixed at a predetermined position that keeps the one side seating surface portions 21a and 21b in a substantially horizontal state, and the user is in a substantially horizontal state. Can be seated stably and comfortably on the seating surface portion 20 held on the seat. In this way, the chair 10 is displaced into a form that can be seated only by an operation in which the user is seated without performing a special operation by the user's hand.

  Furthermore, when the user leaves the seat surface portion 20 in a substantially horizontal state, the seat surface portion 20 returns to its original tilted state again by the urging force of the elastic member 30. In this way, when leaving the chair 10, each one-side seat surface portion 21 a, 21 b of the seat surface portion 20 wraps around from the back when not in use and automatically returns to a state where it can be easily seated. No special operation is required, and it can be easily stored in an inclined state without bothering human hands.
