The seat-side closing portion mounting piece 6 is positioned with respect to the seat frame 3a by inserting the bolts 12 through the bolt holes 6a in a state of being disposed on the seat frame 3a.

  In addition, the chair 1 of this embodiment is provided with the four armrests 7 and the obstruction | occlusion part 8 in the left-right direction, as shown in FIG. The back side blocking part mounting piece 5 and the seat side blocking part mounting piece 6 are provided for each blocking part 8, and four of each are provided.

  The armrest 7 is a rod-like member that supports the hand of the seated person, and in the present embodiment, the armrest 7 is a part that supports the weight of the user by being gripped by the user when sitting and standing. As shown in FIG. 2, the armrest 7 includes a front / rear extension portion 7 a that extends in the front-rear direction of the chair 1 and a vertical extension portion 7 b that extends downward from the front-rear extension portion. ing.

  The front-rear extending portion 7 a is a portion whose rear end is in contact with the front surface of the back-side closing portion mounting piece 5 and extends substantially linearly from the end toward the front of the chair 1. . The front / rear extending portion 7 a is a grip region 7 a 1 where the front portion is gripped by a user, and the rear portion is a closed portion fixing region 7 a 2 where the closed portion 8 is fixed.

  FIG. 4 is a cross-sectional view orthogonal to the extending direction of the gripping region 7a1. As shown in this figure, the gripping region 7a1 has a cross-sectional shape orthogonal to the extending direction, and both sides of the front surface of the gripping area 7a1 face the back side when viewed from the front side in the direction of travel of the user's hand when gripping. The front curved surface 20 is curved so as to spread and bulge outward, and both sides of the back surface are narrowed toward the back and are flat fingertip contact surfaces 21. The user grips the grip region 7a1 of the front-rear extension portion 7a from above when sitting or standing. That is, in the gripping area 7a1, the front side of the user's hand when gripping is on the upper side of the chair 1. Therefore, the front side curved surface 20 in the gripping region 7a1 is a surface formed by curving so that both sides of the upper surface expand downward and swell leftward and rightward. Further, in the grasping region 7a1, the finger pad abutment surface 21 is a surface formed by constricting both sides of the lower surface toward the lower side (the closed portion 8 side) and making it flat.

  Further, the gripping region 7a1 has a front side connection surface 22 that connects the front side curved surfaces 20 and a back side connection surface 23 that connects the finger pad contact surfaces 21 in a cross-sectional shape orthogonal to the extending direction. Have. As described above, the gripping region 7a1 has a circumferential surface formed by the front side curved surface 20, the finger pad abutment surface 21, the front side connection surface 22 and the back side connection surface 23 in the cross-sectional shape.

  In addition, the near side curved surface 20 and the finger pad abutting surface 21 are different from the near side curved surface 20 so that an angle α formed by the tangent line 20a of the near side curved surface 20 and the finger pad abutting surface 21 is an obtuse angle. The finger pad contact surface 21 is connected. Further, the front side connection surface 22 and the back side connection surface 23 are not necessarily flat. For example, the front side connection surface 22 may be a curved surface that smoothly connects to the front side curved surface 20. However, since the front connection surface 22 is a surface that the user hits strongly when depositing his / her weight, it is desirable that the front connection surface 22 be a horizontal plane so that the user's weight can be stably supported.

  The vertically extending portion 7 b is a portion whose lower end is in contact with the upper surface of the seat-side closing portion mounting piece 6 and extends substantially linearly from the end toward the upper side of the chair 1. . The upper and lower extension portions 7b are formed as a gripping region 7b1 where the upper portion is gripped by the user, and the lower portion is a closed portion fixing region 7b2 where the closed portion 8 is fixed.

  FIG. 5 is a cross-sectional view orthogonal to the extending direction of the gripping region 7b1. As shown in this figure, the gripping region 7b1 has a cross-sectional shape orthogonal to the extending direction, and both sides of the front surface are directed to the back side when viewed from the front side of the user's hand when gripping. The front curved surface 20 is curved so as to spread and bulge outward, and both sides of the back surface are narrowed toward the back and are flat fingertip contact surfaces 21. The user grips the grip region 7b1 of the vertically extending portion 7b from the front when sitting or standing. That is, in the gripping area 7b1, the front side of the user's hand when gripping is the front side of the chair 1. Therefore, the front side curved surface 20 in the gripping region 7b1 is a surface formed by being curved so that both sides of the front side surface expand toward the rear side and expand toward the left and right. Further, in the grasping region 7b1, the finger pad abutting surface 21 is a surface formed by constricting both sides of the rear surface toward the rear and making it flat.

  Further, in the cross-sectional shape orthogonal to the extending direction, the grip region 7b1 is in contact with the front side connection surface 22 that connects the front side curved surfaces 20 to each other in the same manner as the grip region 7a1 of the front and rear extension 7a. It has a back side connection surface 23 for connecting the surfaces 21 to each other. The vertically extending portion 7b having the gripping region 7b1 at the upper portion is connected to the front portion of the front / rear extending portion 7a having the gripping region 7a1 at the front, so that the vertically extending portion 7a and the vertically extending portion 7b The installation part 7b is continuously connected.

  Further, as shown in FIG. 3, nuts 13 are embedded in the closing portion fixing region 7a2 of the front / rear extending portion 7a and the closing portion fixing region 7b2 of the vertically extending portion 7b. The armrest 7 is fixed to and supported by the closing portion 8 by screwing the tip of a bolt 14 that passes through the closing portion 8 described later to the nut 13. When the user grips the grip region 7a1 or the grip region 7b1, the palm of the user hits the front connection surface 22 and the finger pad contacts the finger pad contact surface 21.

  Further, as shown in FIG. 3, the vertically extending portion 7 b is inclined so that the upper end is located on the front side of the lower end. As a result, the angle β at which the line segment extending the front-rear extension portion 7a and the line segment extending the vertical extension portion 7b intersect is an acute angle (ie, a right angle or less). In other words, in the present embodiment, the crossing angle between the front-rear extension portion 7a and the upper-lower extension portion 7b is set to be a right angle or less. For this reason, the gripping region 7a1 and the gripping region 7b1 are arranged in front of the case where the crossing angle between the front-rear extending portion 7a and the upper-lower extending portion 7b is an obtuse angle.

  Returning to FIG. 2, the closing portion 8 includes a frame portion 8a, a side plate 8b, and a cover 8c. The frame portion 8 a is a frame body that is opened in a side view and is formed along the outer shape of the closing portion 8. A nut 15 is embedded in the bottom of the frame portion 8a. The nut 15 is screwed into the front end of the bolt 12 that passes through the seat-side closing portion mounting piece 6. Further, bolt holes 8a1 through which bolts 14 to be screwed into the nuts 13 embedded in the armrests 7 are formed in the upper part and the front part of the frame part 8a. The side plate 8b is affixed to the frame portion 8a so as to close the opening of the frame portion 8a from the left-right direction. The cover 8c (not shown in the disassembled portion in FIG. 2) wraps around the frame portion 8a to which the side plate 8b is affixed, and a hole is provided at a place where the bolt 14 is inserted.

  Moreover, the obstruction | occlusion part 8 is made into the shape where the front side upper part was greatly depressed toward the downward direction. By fixing the armrest 7 to such a closed portion 8, an opening 30 surrounded by the armrest 7 and the closed portion 8 is formed. The closing portion 8 is connected to the closing portion fixing region 7a2 and the closing portion fixing region 7b2 of the armrest 7 so as to avoid the holding region 7a1 and the holding region 7b1 so that the holding region 7a1 and the holding region 7b1 face the opening 30. Yes. As shown in FIGS. 1 to 3, such a blocking portion 8 is arranged so as to block between the armrest 7 and the seat 3 while avoiding the gripping region 7 a 1 and the gripping region 7 b 1 of the armrest 7 in the side view. ing.

  Further, the closing portion 8 has a shape on the backrest 4 side (that is, a surface on the backside closing portion mounting piece 5 side) along the surface of the backrest 4. For this reason, the blocking part 8 can be integrated with the backrest 4 by arranging the blocking part 8 in contact with the back blocking part mounting piece 5. It is possible to determine whether or not such a blocking portion 8 is in an accurate position depending on whether or not the blocking portion 8 and the backrest 4 are integrated as described above when assembled. For this reason, alignment with the obstruction | occlusion part 8 and the backrest 4 becomes easy.

  In addition, when attaching such an armrest 7 and the obstruction | occlusion part 8, for example, before attaching the side plate 8b to the frame part 8a, the cover 8c is put on the frame part 8a, and an operator manually puts the cover 8c inside in this state. And the frame portion 8 a and the armrest 7 are fastened by the bolt 14. Thereafter, the side plate 8b is attached to the frame portion 8a and the cover 8c is wrapped. The unit in which the armrest 7 and the closing portion 8 formed in this way are integrated is fixed to the seat side closing portion mounting piece 6 with a bolt 12. As a result, the armrest 7 and the closing portion 8 are fixed to the seat-side closing portion mounting piece 6.

  For example, when a user who has reduced strength of fingers or lower limbs sits on the chair 1 of the present embodiment, the grip region 7a1 of the armrest 7 is gripped from above, or the grip region 7b1 of the armrest 7 Is held from the front, and the seating operation is performed with the weight of the armrest 7 being deposited. In addition, when the seated person stands, the gripping area 7a1 of the armrest 7 is gripped from above, or the gripping area 7b1 of the armrest 7 is gripped from the front, and the standing motion is performed by depositing weight on the armrest 7. Is called.

  According to such a chair 1 of this embodiment, the closed part 8 which closes the space between the seat 3 and the armrest 7 is provided. For this reason, it is possible to prevent the luggage or the like from dropping from the sitting space through the space between the seat 3 and the armrest 7 by the closing portion 8. Further, according to the chair 1 of the present embodiment, the closing part 8 closes only a part of the space so as to avoid the gripping area 7a1 and the gripping area 7b1 of the armrest 7. For this reason, when the user grips the grip region 7 a 1 or the grip region 7 b 1 of the armrest 7, the blocking portion 8 does not get in the way, and the user can grip the armrest 7 so as to wrap it. Therefore, according to the chair 1 of the present embodiment, it is possible to prevent the luggage or the like from falling from its seating space and to deposit the weight with respect to the armrest 7 with peace of mind.

  Moreover, in the chair 1 of this embodiment, the armrest 7 has the front-back extension part 7a extended in the front-back direction of the chair 1, and the up-down extension extended below from the front part of the said front-back extension part 7a. It is set as the shape which has the installation part 7b. Such an armrest 7 has a shape in which the front portion of the front-rear extension portion 7 a projects to the front side in the armrest 7. And in the chair 1 of this embodiment, since the holding | grip area | region 7a1 and the holding | grip area | region 7b1 are provided in the front part of the front-back extension part 7a which is the site | part projected on the front side in the armrest 7, the user sat down. The grip region 7a1 and the grip region 7b1 are provided at a position where the armrest 7 can be easily gripped when standing up from the state or sitting from the stand state. Therefore, it is possible to deposit the weight more safely with respect to the armrest 7.

  Moreover, in the chair 1 of this embodiment, since the crossing angle of the front-back extension part 7a and the up-and-down extension part 7b is an acute angle, the shape of the armrest 7 is the front-back extension in which the holding | grip area | region 7a1 was formed. The front part of the part 7a has a shape protruding more forward. Therefore, it is possible to deposit the weight more safely with respect to the armrest 7.

  In addition, the chair 1 of the present embodiment has a gripping area 7a1 and a gripping area 7b1 provided in at least a part of the extending direction of the armrest 7, and is orthogonal to the extending direction of the gripping area 7a1 and the gripping area 7b1. In the cross-sectional shape, the front side curved surface that is curved so that both sides of the front side surface expand toward the back side and swell toward the outside when viewed from the front side of the user's hand when gripping 20, both sides of the back surface are narrowed toward the back and are finger pad contact surfaces 21 made of a flat surface.

  For example, in the case where the cross-sectional shape is a rectangular armrest, when the user grips, there is a corner on the user's hand side. For this reason, this corner | angular part hits a user's hand belly, the base of a finger, etc. When a user who has reduced strength of fingers or lower limbs grips such an armrest, it may be difficult for the auxiliary member to grip because the corners interfere. On the other hand, in the present embodiment, the front side curved surface 20 is curved so that both sides of the front side surface expand toward the back side and swell toward the outside. For this reason, when a user grips, the corner portion does not disturb the armrest 7 so that the armrest 7 can be easily gripped, and it is possible to deposit the weight on the armrest 7 with peace of mind.

  Similarly, when the cross-sectional shape is a rectangular armrest, when the user grips, the user's finger pad is usually caught in the corner on the back side. When the corner portion and the finger pad abut, only a small part of the finger pad comes into contact with the armrest, and the contact area is small. For this reason, it may be difficult to grasp when a user who has weak muscles of fingers or lower limbs grasps it. On the other hand, in the chair 1 of this embodiment, the both sides of the surface of the back side are made into the finger pad contact surface 21 which becomes narrow toward the back side and consists of a plane. For this reason, since the user's finger pad and the armrest 7 are brought into surface contact with each other, the armrest 7 can be easily grasped, and the weight can be deposited on the armrest 7 with peace of mind. Furthermore, since both sides of the back surface are constricted toward the back side, the circumference of the armrest 7 is shorter than that in the case where the thickness is the same and the cross-sectional shape is rectangular. For this reason, it becomes easy for a user's hand to wrap the armrest 7, and even a user whose muscle strength of fingers or lower limbs is lowered can safely deposit the weight on the armrest 7.

  As described above, according to the chair 1 of the present embodiment, it is possible for a user whose muscle strength of fingers and lower limbs is reduced to deposit his / her weight safely, and therefore particularly suitable for a hospital or a nursing facility. Become.

  Moreover, in the chair 1 of this embodiment, the front side curved surface 20 and the finger pad abutment surface 21 are set so that the angle α formed by the tangent line 20a of the front side curved surface 20 and the finger pad abutment surface 21 becomes an obtuse angle. And are connected. For this reason, the corner | angular part formed in the connection location of the front side curved surface 20 and the finger pad contact surface 21 becomes gentle, and the discomfort when the said corner | angular part contact | abuts a user's hand is reduced. Is possible.

  Moreover, in the chair 1 of this embodiment, the up-and-down extending part 7b is provided with the upper part connected with the front part of the front-back extending part 7a, and was made into the holding | grip area | region 7b1. For this reason, since the holding region 7b1 is also provided on the upper part of the vertically extending part 7b, the user must hold the front part of the front and rear extending part 7a and the upper part of the vertically extending part 7b which is easier to grip. So, you can leave your weight on the armrest 7 with peace of mind. For this reason, it becomes possible for the user whose muscular strength of fingers and lower limbs is lowered to use it with more peace of mind.

  Moreover, in the chair 1 of this embodiment, the front-back extension part 7a and the up-and-down extension part 7b are connected continuously. For this reason, even if it is a case where a user hold | grips the connection location of the front-back extension part 7a and the up-and-down extension part 7b, he can leave a weight with respect to the armrest 7 in comfort.

  Moreover, in the chair 1 of this embodiment, since the surface by the side of the backrest 4 of the obstruction | occlusion part 8 becomes a shape along the backrest 4, alignment with the obstruction | occlusion part 8 and the backrest 4 becomes easy. It is possible to stabilize the position of the closing portion 8 relative to the backrest 4.
