Abstract: A booth includes a booth main body including a facing panel, a right-side panel, and a left-side panel, a top plate, and an inclined panel that extends from a booth left front-end portion of the right-side panel of the booth main body while being inclined to become farther from the facing panel toward the right-side panel in the plan view and forms an entrance into the booth main body between the inclined panel and a booth right front-end portion of the right-side panel of the booth main body. The top plate includes a panel side edge portion that extends along at least the facing panel and the right-side panel, and a front edge portion that includes a first edge portion that becomes closer to the facing panel from a first end on the right-side panel side of the front edge portion toward the left-side panel.

Abstract: A management system is a management system which includes a remote work system having at least one master unit and a plurality of slave units which can be remotely operated and a management server, in which each of the plurality of slave units includes a gripping unit that is configured to grip a target, grip the target by means of autonomous control, and, when being connected to the master unit by the management server, grip the target by means of a remote operation by the master unit, the master unit is configured to perform the remote operation on the plurality of slave units, and the management server includes an operation management unit that is configured to connect the master unit and the plurality of slave units when a remote operation is required.

Abstract: A backrest includes: a backrest body against which a seated person leans a back thereof, a backrest support positioned behind and supporting the backrest body; and an armrest body provided outside in a width direction of the backrest body and supported by the backrest support so as to move up and down at a position separated from the backrest body. A chair includes the above-described backrest.

Abstract: This panel (1) has a panel body (10) and a leg (20) that supports the panel body (10). The leg (20) has a shaft (22) that is inserted into the panel body (10), and a leg body (21) to which the shaft (22) is fixed and that is disposed outside of the panel body (10). The leg body (21) is provided with a first rotation stopper (31) that is in direct contact with at least either one of the front face (10A) and the back face (10B) of a panel face of the panel body (10) and that stops rotation of the panel body (10) in one direction around the shaft (22), and a second rotation stopper (32) that is configured to stop the rotation of the panel body (10) in the direction opposite to the one direction.

Abstract: A load support structure for a chair includes a tensile material on which a load support surface configured to receive a load of a seated person is formed, a pair of support sections (51) to which the tensile material is attached, and which is elastically deformable in response to a force acting from the tensile material, a first reinforcing section (41) which is disposed to be spaced apart from the pair of support sections (51) in a surface perpendicular direction perpendicular to the load support surface, is located on a side opposite to the load support surface, and extends along an extending direction of the support section, and a connecting body which connects each of both end portion sides of the support section (51) with a corresponding end portion side of both end portion sides of the first reinforcing section (41), in which the support sections (51) are disposed outside the first reinforcing section (41) in a view of the surface perpendicular direction from the load support surface side.

Abstract: An armrest according to the present invention includes a support member (8a, 215, 308a) which is a support structure, and an armrest main body (8b, 216, 308b), the armrest main body (8b, 216, 308b) includes a lower layer member (8j) including an operation lever (8p, 235, 308p) which is supported by a support member (8a, 215, 308a) to be movable in a forward-and-rearward direction and is operated by a seated person, and an upper layer member (8k) supported by the lower layer member (8j) to be movable in right-and-left direction, and the upper layer member (8k) covers the operation lever (8p, 235, 308p) at a base position in the right-and-left direction.

Abstract: A backrest (7) includes: a tensile material (71) on which a load support surface (71f) configured to receive a load of a seated person is formed; a back front frame (80F) that supports an outer peripheral end portion (71e) of the tensile material (71); an attachment portion (87) which is formed in the back front frame (80F) and faces the tensile material (71) in a state where the attachment portion (87) is separated from the tensile material (71) in a direction intersecting the load support surface (71f); and a lumber support (200) that is attachable to and detachable from the attachment portion (87), in which the lumber support (200) includes an attaching portion (222) which extends in a direction along the load support surface (71f), is inserted into a gap (S) between the tensile material (71) and the attachment portion (87), and is fixed to the attachment portion (87).
