Folding kneeling chair

Abstract

To provide a seiza stool that can be easily carried in a folding state, that can be easily spread in use, and that is strong and hardly breakable.SOLUTION: The foldable seiza stool 1 includes: a pair of bottomed open box-shaped leg parts 20 that support a load; a bisected seat part body 10 that has a seating face 12 and that also has on the opposite side from the seating face 12 a bottomed open box-shaped leg storage part 14 for storing a pair of leg parts 20; a hinge part 16 that rotatably connect the bisected seat part body 10 by a revolving shaft 18 which is situated on the opposite side from the seating face 12; and a leg shaft 22 that makes the respective leg parts 20 journaled by both ends of the seat part body 10 rotatably between the stored position and the use position. The respective seat part body 10 rotates around the axis of revolution 18 of the hinge part 16, comes into contact with each other in the use position, with a roughly flush face formed on the seating face 12, and is superposed on each other in a manner that the pair of leg parts 20 stored in the leg storage part 14 in a folding position are oppositely faced.SELECTED DRAWING: Figure 1

Claims

1. It is a foldable kneeling chair, A pair of bottomed, open, box-shaped legs that support the load, The seat body is divided into two parts and has a seat surface and a bottomed, open box-shaped leg housing section on the opposite side of the seat surface that accommodates the pair of legs, A hinge portion that rotatably connects the two-part seat body with a pivot axis located on the opposite side of the seat surface, The seat body is provided with leg shafts that pivotally support each of the legs so that they can rotate between a storage position and a usage position at both ends of the seat body, Each of the aforementioned seat bodies rotates around the pivot axis of the hinge, and in the usage position they come into contact with each other and form approximately the same plane on the seat surface, while in the folded position the pair of legs housed in the leg housing overlap each other so as to face each other. Each of the aforementioned legs has a side surface on the outer side of the leg axis, is approximately perpendicular to the seat body in the usage position, and supports the load with the outer side surface on the leg axis side. The leg housing section accommodates each leg from the end on the leg axis side to the end on the opposite side of the leg axis in the housing position. The storage configuration of the aforementioned kneeling chair is a box shape in which the seat surfaces of each seat body are arranged to face each other in roughly parallel directions. The leg shaft is provided to be able to move back and forth and has a claw portion that is biased in the direction of advancement. Each bearing portion of the leg shaft has a groove that allows the leg to move parallel in a predetermined direction when the claw portion is fitted, Each of the aforementioned seat bodies has a concave fixing portion on the back surface of the seat surface on the leg axis side, Each of the aforementioned legs has a pair of claw holes provided on both sides of the end of the leg on the axis side, The claw portion is longer inward than the axial length of the bearing portion, and a portion of the claw portion on the axially inward side of the bearing portion is inserted into and fixed in the claw hole of the leg portion. When each of the aforementioned legs is rotated from its storage position to its usage position, the claw portion advances in the direction of the groove portion and engages with the groove portion, preventing the rotation of each leg portion. At the same time, the end portion of each leg portion facing the leg tip moves parallel to the direction in which it engages with the fixing portion, and by engaging the end portion with the fixing portion and bringing the outer side surface into contact with the fixing portion, each leg portion is fixed in the usage position. Each of the aforementioned legs is retracted and rotated by pulling its end out from the fixing part from its position of use, thereby housing each of the legs in the leg housing part of the respective seat body. A kneeling chair characterized in that the forward and backward movement of the claw portion and the parallel movement of the leg portion are performed in an integrated manner.

2. It is a foldable kneeling chair, It has a seat surface and is divided into two parts, each a bottomed, open, box-shaped seat body, A pair of legs, each having a bottomed, open, box-shaped body housing section that accommodates each of the aforementioned seat bodies, A pair of hinges that rotatably connect one seat body and one leg, and the other seat body and the other leg, The device comprises a support member that supports the rotation axis of each of the aforementioned hinge parts and defines the usage position of the seat body, Each of the aforementioned seat bodies rotates around the pivot axis of each hinge, and in the usage position, it contacts the support member and forms a substantially identical plane on the seat surface, while in the storage position, it is superimposed facing the main body housing while housed in the main body housing, Each of the aforementioned legs rotates around the pivot axis of each of the aforementioned hinges, and in the usage position, it is approximately perpendicular to each of the aforementioned seat bodies, and in the folded position, the respective seat bodies housed in the main body storage section overlap each other so as to face each other. The main body housing section houses the main body of each seat from the pivot axis on the hinge side to the end opposite the hinge in the housing position. The rotation axes of the pair of hinges are substantially parallel. The storage configuration of the kneeling chair is characterized in that the undersides of the bottom of the main body housing for the pair of legs are box-shaped and facing each other substantially parallel to one another.

3. Each of the aforementioned seat bodies has a stopper on a part of the outer edge of the fixing portion on the back surface of the seat on the leg axis side that restricts the rotation angle of each leg, The kneeling chair according to claim 1, characterized in that when each of the legs is rotated from the storage position to the usage position, the rotation angle is restricted by the stopper.
