  The opening / closing part is formed of a flexible member. The opening / closing part has a second connection part connected to the first connection part. The opening / closing portion is connected to a connection position in the vicinity of the upper portion between the adjacent first leg portion and second leg portion. The opening / closing unit is, for example, a closing body 101, 201, 301, 401, 501 described later. The second connection part is, for example, a hook-and-loop fastener 133, 134, 233 to 236 described later. The connection positions are, for example, horizontal bars 115 and 315 and connection positions 251, 451, and 551 described later. The plate members are, for example, plate members 135, 237, and 238 described later. The connection position in the vicinity of the upper side is a position in the vicinity of the upper side between the leg 111 and the leg 112 that satisfies the following condition with the closed body connected to the connection position. The condition is that when the chair is in the closed state, the lower side of the closed body can be arranged outside the horizontal beam 116, and when the open / closed state of the chair is switched, the closed body can pass through the opening from above the horizontal beam 116. This is the condition.

  The opening / closing part opens between the legs when the first connecting part and the second connecting part are connected, and closes between the legs when the first connecting part and the second connecting part are not connected. To do. The distance between the legs is, for example, between the legs 111 and 112, between the legs 111 and 113, between the legs 112 and 114, and between the legs 113 and 114, which will be described later.

  The opening / closing part has a length that covers the open part between the connection position and the horizontal beam part and a flexibility that can pass through the open part from above the horizontal beam part when connected to the connection position.

FIG. 1 is a diagram (part 1) illustrating an example of use of a chair.
With reference to FIG. 1, the thermal insulation function of the chair used in combination with a dining kotatsu will be described.
The chair 1 has a closing body 101 that closes between the two legs at the rear. And the chair 1 is used so that a seat surface may enter in the kotatsu futon 6 used by the dining kotatsu 5. FIG. Thus, the chair 1 has the heat insulation function which suppresses that the warm air of the dining kotatsu 5 escapes from between the legs of a rear part by having the obstruction | occlusion body 101. FIG.

FIG. 2 is a diagram illustrating an example of a closed state.
FIG. 2 is a rear perspective view of the chair 1. The configuration of the chair 1 will be described with reference to FIG.
The chair 1 includes, for example, a closing body 101, a leg 111, a leg 112, a leg 113, a leg 114 (not shown), a horizontal rail 115, a horizontal rail 116, a seat 121, and a backrest 122. Is provided. In the following description, the surface of the seat portion 121 is also referred to as a seat surface, and the back surface of the seat portion 121 is simply referred to as a back surface. The legs 111 to 114, the horizontal rail 115, and the horizontal rail 116 are made of a member having rigidity or quasi-rigidity such as wood, plastic, aluminum, stainless steel, and iron.
The legs 111 to 114 are provided below the seat 121 and support the seat 121.

  The horizontal rail 115 is stretched between the leg 111 and the leg 112 at a position substantially the same height as the seat portion 121. The horizontal rail 116 is stretched between the legs 111 and 112 below the horizontal rail 115. The horizontal rail 115 may be provided at a position different from that of the seat 121 as long as the horizontal rail 115 is provided between the leg 111 and the leg 112 at a position above the horizontal rail 116. Good.

  And the horizontal rail 116 is provided in the horizontal direction outer side of the horizontal rail 115 seeing from the bearing surface upper side. In the following description, the horizontal direction outer side of the horizontal rail 115 when viewed from the upper side of the seating surface is also simply referred to as the outer side of the horizontal rail 115. In addition, the crosspiece 116 may be excluded from the constituent elements, and the configuration of the chair 1 may be further simplified.

  The closing body 101 is connected so that one side is wound around the crosspiece 115. In the following description, a portion that is wound around and connected to the crosspiece 115 of the closing body 101 is also referred to as a connection portion. The portion other than the connection portion of the closure body 101 is also referred to as a closure portion. Further, for convenience of explanation, in the closing body 101, it is assumed that the connection portion is the upper side and the closing portion is the lower side.

With reference to FIG. 2, the obstruction | occlusion state of the obstruction body 101 is demonstrated.
As shown in FIG. 2, the closing body 101 has a length that covers an open portion between the leg 111, the leg 112, the horizontal rail 115, and the horizontal rail 116. The lower end of the closed portion of the closing body 101 is disposed so as to be positioned on the outer side in the horizontal direction of the horizontal rail 116 when viewed from above the seating surface when closing the space between the legs 111 and 112. This state is referred to as a closed state of the chair 1. In the following description, when viewed from the upper side of the seating surface, the horizontal outer side of the horizontal rail 116 is also simply referred to as the outer side of the horizontal rail 116.

  In the closed state of the chair 1, the horizontal rail 116 is positioned outside the horizontal rail 115, and thus the closing body 101 is subjected to a force that rotates in the downward direction of the seat portion 121 with the horizontal rail 115 as a center point. Become. Thereby, the obstruction body 101 is fixed so that the lower side of the obstruction portion is pressed against the crosspiece 116. Therefore, since the chair 1 closes between the leg 111 and the leg 112 without the swinging body 101 swinging when in the closed state, the heat shielding performance can be improved as compared with the case without the cross rail 116. Further, when the chair 1 is in the closed state, the closed body 101 can be fixed without increasing the number of parts only by limiting the positional relationship between the horizontal rail 115 and the horizontal rail 116.

FIG. 3 is a diagram illustrating an example of an open state.
FIG. 3 is a rear perspective view of the chair 1. With reference to FIG. 3, the open state of the obstruction body 101 will be described.
As shown in FIG. 3, the closing body 101 is folded on the back side of the seat 121 when the space between the legs 111 and 112 is opened. And the closure body 101 is affixed on the back surface of the seat part 121 using a hook-and-loop fastener, and is fixed. This state is referred to as an open state of the chair 1.

FIG. 4 is a diagram (No. 1) illustrating an embodiment of an occlusion body.
The obstruction body 101 will be described with reference to FIG.
The closing body 101 includes a main body 130, hook-and-loop fasteners 131 to 134, and a plate member 135 indicated by a broken line. In FIG. 4, a region including the hook-and-loop fastener 131, the hook-and-loop fastener 132, and the area between the hook-and-loop fastener 131 and the hook-and-loop fastener 132 is a connection portion. Further, a region from the lower end of the hook-and-loop fastener 132 to the lower end of the closing body 101 is a closing portion.
The main body 130 is configured by a member having flexibility. The main body 130 is configured using, for example, a member having flexibility such as cloth, synthetic leather, main leather, and synthetic resin.

  The hook-and-loop fastener 131 and the hook-and-loop fastener 132 are a pair of sets, and are bonded to each other when the closure body 101 is wound around the crosspiece 115. Thereby, the obstruction body 101 is detachably connected to the crosspiece 115 of the chair 1. The chair 1 and the closure body 101 may be provided with any detachable connecting means such as a snap button or a magnet, instead of the hook-and-loop fastener. Although not particularly specified below, each hook-and-loop fastener can be replaced with any removable connecting means such as a snap button or a magnet.

  The hook-and-loop fastener 133 is a pair of a hook-and-loop fastener 143 described later and is bonded to each other when the chair 1 is opened. The hook-and-loop fastener 134 is a pair of a hook-and-loop fastener 144 described later and is bonded to each other when the chair 1 is opened. That is, when the hook-and-loop fastener is bonded, the closure body 101 is fixed substantially in parallel to the back surface of the chair 1, so that the chair 1 is in an open state.

The plate member 135 is configured by a plate-like member having rigidity or semi-rigidity. The plate member 135 is provided in the closed portion of the closing body 101. Further, the plate member 135 is formed of a member having rigidity or semi-rigidity such as wood, iron, and plastic. Since the chair 1 has the plate member 135 in the closed body 101, when the chair 1 is in the closed state, it is possible to improve the heat insulation property of the warm air and the fixing force to the crosspiece 116. Furthermore, the chair 1 has the plate member 135 in the closure body 101, so that when the chair 1 is in an open state, the deflection of the closure body 101 fixed on the back surface of the seat portion 121 can be suppressed.
The installation position, size, and shape of the plate member 135 are selected such that a bent region a1 is formed between the lower end of the hook-and-loop fastener 132 and the upper end of the plate member 135.

  The plate member 135 may be provided inside the main body 130. At this time, the plate member 135 is provided inside the main body 130 by being inserted into the bag-shaped main body 130, for example. Further, the plate member 135 may be attached to the surface of the main body 130. The configuration of the chair 1 may be simplified by excluding the plate member 135 from the constituent elements. Also in this case, since the closed portion of the closed body 101 has flexibility as a whole, the closed state similar to that of the closed body 101 having the bent region a1 can be switched.

  The bent region a1 is integral with the main body 130. Since the plate member 135 does not exist in the bending region a1, the bending region a1 has the same flexibility as the main body 130. For this reason, the closure body 101 of the chair 1 is fixed to the back surface of the seat 121 by bending the bending region a1 without using other parts such as a hinge. Therefore, the chair 1 can facilitate maintenance and management of the closed body with a simple configuration. The bent region a1 is not limited to a structure that is integral with the main body 130, but may be formed of a different material and connected between the lower end of the hook-and-loop fastener 132 and the upper end of the plate member 135. In this case, a member having flexibility that is superior in folding resistance to the member of the main body 130 may be used in the bending region a1.

The obstruction body 101 can be configured to be lightweight and inexpensive by using a lightweight wood such as a cloth as the main body 130 and a MDF (medium density fiberboard) as the plate member 135.
Although not specifically mentioned below, the above-described members are selectively used as appropriate for each main body and each plate member.

FIGS. 5 to 7 are views (No. 1) to (No. 3) showing an embodiment of the chair.
5 to 7 are bottom views of the chair 1. The chair 1 will be described with reference to FIGS.
5 to 7, the same reference numerals are given to the configurations described in FIG. 2, and descriptions thereof are omitted.
As shown in FIG. 5, the chair 1 includes a connection hole 141, a hook-and-loop fastener 143, and a hook-and-loop fastener 144.
As shown in FIG. 6, the connection hole 141 passes the connecting portion of the closure body 101 and connects the hook-and-loop fastener 131 and the hook-and-loop fastener 132 to attach the closure body 101 to the horizontal rail 115 when the closure body 101 is attached. It is a hole for winding.

  The hook-and-loop fastener 143 is a pair with the hook-and-loop fastener 133, and is bonded together when the chair 1 is opened as shown in FIG. The hook-and-loop fastener 144 is a set of a pair with the hook-and-loop fastener 134 and is bonded to each other when the chair 1 is opened as shown in FIG. Note that the hook-and-loop fasteners 133 and 134 and the hook-and-loop fasteners 143 and 144 are not limited to the positional relationship and shape shown in FIG. As long as the hook-and-loop fasteners 133 and 134 and the hook-and-loop fasteners 143 and 144 are bonded together as a pair, and the closure body 101 can be fixed to the back surface of the seat 121, an arbitrary positional relationship and shape can be selected. It is.

FIGS. 8 to 11 are diagrams (No. 1) to (No. 4) for explaining switching of the open / close state.
8 to 11 are right side views of the chair 1. With reference to FIGS. 8 to 11, switching between the open state and the closed state of the chair 1 will be described.
As shown in FIG. 8, when the lower end of the closing body 101 is disposed outside the crosspiece 116, the chair 1 is switched to the closing state. The horizontal crosspiece 116 is provided, for example, so as to be positioned outside the horizontal crosspiece 115 by a space S1. Then, in the closed state of the chair 1, the horizontal rail 116 is positioned outside the horizontal rail 115, and thus the closing body 101 is subjected to a force that rotates in the downward direction of the seat portion 121 with the horizontal rail 115 as a central point. It will be. Thereby, when the chair 1 is in the closed state, the closed side of the closed body 101 is fixed to the crosspiece 116. The size of the space S <b> 1 is appropriately set so that, in the closed state of the chair 1, a force that rotates in the lower direction of the seat portion 121 around the horizontal rail 115 acts on the closed body 101.

  As shown in FIG. 9, when the closed state of the chair 1 is switched, the closing body 101 is deformed so that the bending region a <b> 1 is bent and passes through the upper side of the horizontal rail 116. Thus, since the closing body 101 has the bending area | region a1, even if it provides the rigid board member 135 in the obstruction | occlusion part, it can pass through an open part from the upper direction of the horizontal crosspiece 116. Similarly, the closing body 101 having the configuration excluding the plate member 135 can pass through the open portion from the upper side of the crosspiece 116 because the closing portion has overall flexibility.

As shown in FIG. 10, the closing body 101 is rotated around the horizontal rail 115 below the seat 121 when the open / close state is switched.
As shown in FIG. 11, when the surface fasteners 133 and 134 of the closing body 101 are connected to the surface fasteners 143 and 144 provided on the back surface of the seat 121, the chair 1 is switched to the open state.

FIG. 12 is a diagram (No. 2) illustrating an embodiment of the occlusion body.
With reference to FIG. 12, a closing body 201 which is a modified example of the closing body 101 will be described assuming that the closing body 201 is connected to the chair 1.
The closing body 201 includes a main body 230, hook-and-loop fasteners 231 to 236, and plate members 237 and 238 indicated by broken lines. In FIG. 12, a region including the surface fastener 231, the surface fastener 232, and the area between the surface fastener 231 and the surface fastener 232 is a connection portion. Further, a region from the lower end of the hook-and-loop fastener 232 to the lower end of the closing body 201 is a closing portion.

  The main body 230 is configured by a member having flexibility. As with the main body 130, the main body 230 is configured using a member having flexibility such as cloth, synthetic leather, main leather, and synthetic resin.

  The hook-and-loop fastener 231 and the hook-and-loop fastener 232 are a pair of sets, and are bonded to each other when the closing member 201 is wound around the horizontal rail 115. Thereby, the obstruction body 201 is detachably connected to the crosspiece 115 of the chair 1.

  The hook-and-loop fasteners 233 and 235 are a pair with the hook-and-loop fastener 143, and are attached to each other when the chair 1 is opened. The hook-and-loop fasteners 234 and 236 are a pair of sets with the hook-and-loop fastener 144 and are bonded to each other when the chair 1 is opened. In other words, when the hook-and-loop fastener is bonded, the closing body 201 is fixed to the back surface of the chair 1 substantially in parallel, so that the chair 1 is in an open state. The hook-and-loop fastener 143 may include two hook-and-loop fasteners 143a and 143b corresponding to the hook-and-loop fasteners 233 and 235, respectively. The hook-and-loop fastener 144 may include two hook-and-loop fasteners (not shown) including 144a and 144b, corresponding to the hook-and-loop fasteners 234 and 236, respectively.

  The plate members 237 and 238 are plate-shaped members having rigidity or semi-rigidity. The plate members 237 and 238 are provided in the closed portion of the closing body 201. Further, the plate member 135 is formed of a member having rigidity or semi-rigidity such as wood, iron, and plastic. The chair 1 has the plate members 237 and 238 in the closed body 201, so that when the chair 1 is in the closed state, it is possible to improve the heat shielding property of the warm air and the fixing force to the side rail 116. Furthermore, the chair 1 has the plate members 237 and 238 in the closing body 201, so that the bending of the closing body 201 fixed on the back surface of the seat portion 121 can be suppressed when the chair 1 is in the open state.

  The installation positions, sizes, and shapes of the plate members 237 and 238 are bent between the lower end of the hook-and-loop fastener 232 and the upper end of the plate member 237, and between the lower end of the plate member 237 and the upper end of the plate member 238, respectively. The region a2 and the bent region a3 are selected to be formed.

  The bent regions a2 and a3 are an integral part of the main body 230. Since the plate members 237 and 238 do not exist in the bending region a2, the bending region a2 has the same flexibility as the main body 230. For this reason, the closure body 201 of the chair 1 can switch the open / close state of the chair 1 by bending the bending region a <b> 2 without using other parts such as a hinge. The bent region a2 is not limited to a configuration that is integrated with the main body 230, but may be formed of a different material and connected between the lower end of the hook-and-loop fastener 232 and the upper end of the plate member 237. In this case, you may use the member which has the flexibility which was excellent in folding tolerance compared with the member of the main body 230 in the bending area | region a2.

  As described above, the closing body 201 further includes the bending area a3 in addition to the bending area a2 corresponding to the bending area a1 of the closing body 101. Thereby, when the closed body 201 switches the open / closed state of the chair 1, the bent area a3 is also bent in addition to the bent area a2, so that the passage through the upper side of the crosspiece 116 is compared with the configuration of the closed body 201. Can be easily. The bent region a3 is not limited to a structure that is integral with the main body 230, but may be formed of a different material and connected between the lower end of the hook-and-loop fastener 237 and the upper end of the plate member 238. In this case, a member having flexibility that is superior in folding resistance to the member of the main body 230 may be used in the bending region a3. Further, the closed portion of the closing body of the chair may be provided with three or more plate members, and the bent region may be provided in a region between the connection portion and a region between the respective plate members.

FIG. 13 is a diagram (part 4) illustrating an embodiment of the chair.
A modified example of the chair will be described with reference to FIG. The same components as those of the chair 1 shown in FIG.
The chair 2 includes a closing body 301.
The closure body 301 has a configuration in which the hook-and-loop fastener 131 and the hook-and-loop fastener 132 are excluded from the closure body 101. Then, the closing body 301 is connected to the connection position 251 on the back surface of the seat 121 by an arbitrary connection means such as an adhesive or a tucker. Thereby, the chair 2 can reduce the number of parts of the closing body 301 compared with the closing body 101.

  When the chair 2 is in the closed state, the connection position 251 can be disposed on the outside of the horizontal bar 116 on the lower side of the closed body 301. When the open / close state of the chair 2 is switched, the closed body 301 is opened from above the horizontal bar 116. It is provided at a position near the upper part between the legs 111 and 112 that can pass through the section. At this time, for example, the horizontal rail 116 is provided so as to be positioned outside the connection position 251 by the space S2. The size of the space S <b> 2 is appropriately set so that a force that rotates in the lower direction of the seat portion 121 around the connection position 251 acts on the closed body 301 in the closed state of the chair 2.

FIG. 14 is a diagram (No. 5) illustrating an embodiment of the chair.
