DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment embodying the present invention will be described. 1 is a perspective view of a service core and a desk as furniture to which the present invention is applied, FIG. 2 is a side view of the service core and a desk, FIG. 3 is a plan view of the service core and a desk, and FIG. 5 is a perspective view of the beam body, FIG. 6 is a bottom view of the lid body, FIGS. 7A to 7F are plan views of the beam body and cross-sectional views of predetermined portions thereof, and FIG. 8 relates to the present invention. It is a principal part expanded sectional view of a guide connection device.
[0012]
As shown in FIGS. 1 to 3, in the desk 1 of the present invention, a desk top plate 2 having a substantially semicircular shape in plan view is supported by leg bodies 4 on both left and right sides, and adjacent to the outer peripheral side of the table top plate 2. Thus, the service core 3 as one or a plurality of furniture is arranged. As shown in FIG. 3, the outer peripheral edge 2 a of the tabletop plate 2 is a substantially semicircular circumference having a radius R <b> 1 from the center O serving as the center of rotation, and the center portion of the inner peripheral edge of the tabletop plate 2 has a radius in plan view. When the body of the worker (person H0) is placed near the center O, the concave edge 2b is formed so as not to hit the outer periphery of the body. Is formed. In the embodiment, the radius R1 of the outer peripheral edge 2a of the tabletop plate 2 is approximately 600 mm to 800 mm, preferably 750 mm. The radius R2 of the concave edge 2b is set to about 350 mm.
[0013]
The tabletop 2 is supported by a pair of left and right height-adjustable legs 4, 4. As will be described later, the leg 4 includes an upper column 81 attached to the lower surface of the tabletop 2. The lower leg column 4a that can be adjusted up and down, and the banana-shaped (substantially arc-shaped) horizontal foot 4b in plan view. That is, the upper support 81 is slidably inserted in advance into a guide hole formed in the upper end flange 83b of the upper guide member 83 made of synthetic resin. The downward outer mounting piece 83a of the upper guide member 83 is bolted to a plate piece 85 welded and fixed to the outer surface of the upper end portion of the lower leg column 4a, while the outer surface of the upper column 81 and the inner surface of the lower leg column 4a. A horizontal portion 87a at the upper end of the plate-like spacer 87 interposed therebetween is supported between the lower surface of the upper end flange portion 83b of the upper guide member 83 and the upper end edge of the lower leg column 4a so as not to fall off. The spacer 87 is pressed against the upper support 81. Engagement pins 89 are horizontally inserted into adjustment holes 88 drilled in the upper support column 81 at appropriate intervals (see FIGS. 11 and 12), and the engagement pin 89 protrudes from the upper support column 81. The front and rear portions thus set are set on a mounting portion 90 that is recessed in the upper end flange 83 b of the upper guide member 83. The protrusion 91 provided on one side of the mounting portion 90 prevents the engaging pin 89 that can be inserted and removed from coming off when the head 89 a of the engaging pin 89 abuts.
[0014]
On the other hand, the horizontal foot 4b is disposed so as to be substantially along the inner diameter side of the outer peripheral edge of the tabletop plate 2 in a plan view, and a plurality of casters 5 are attached to the lower surface of each horizontal foot 4b. In FIG. 4, the lens is configured to be rotatable around the center O.
[0015]
On the other hand, a bracket 84 is fixed to the lower surface of the tabletop plate 2 with respect to the lower leg column 4a having an elliptical cross section in each leg 4, and the rectangular column-shaped upper column 81 protruding downward from the bracket 84 is vertically moved. It is inserted in an adjustable manner. Therefore, a synthetic resin lower guide member 82 fixed to the lower end of the upper column 81 is slidably inserted into the lower leg column 4a.
[0016]
Further, the lower surface of the tabletop 2 near the outer periphery is fixed by embedding and fixing a guide rail 6 having a downwardly U-shaped cross section opened downward in an arc shape in plan view. A part of the guide means when the tabletop 2 rotates horizontally in a state of being connected to the service core 3 is constituted. Further, as shown in FIGS. 3 and 9, the lower surface of the tabletop plate 2 has a substantially circular shape in plan view having a recessed portion 90 a having a radius of curvature of approximately 110 mm on both the left and right sides near the recessed edge portion 2 b. Handle portions 90 and 90 having a diameter of about 110 mm are embedded. Thereby, it is easy for an operator (person H0) sitting on the chair 11 in the vicinity of the center O to place his / her hands on the pair of handle portions 90 and to turn the table top 2 in the left-right direction. become. The form of the handle portion 90 may slightly protrude downward from the lower surface of the tabletop plate 2.
[0017]
The service core 3 can be independent from the support 7 made of metal such as aluminum extruded material or synthetic resin, and the horizontal foot 9 in contact with the floor surface. The lower end of the column 7 is connected and fixed to a substantially central portion in the longitudinal direction with a bolt or the like (not shown). In addition, the self-supporting stability is improved by the auxiliary horizontal feet 10 extending from the horizontal feet 9 in the inner peripheral direction below the tabletop 2 (see FIGS. 2 and 3). The upper surface of the auxiliary horizontal foot 10 is also used as a footrest portion of the person H0 sitting on the chair 11 so as to face the concave edge portion 2b of the tabletop board 2. Further, the wagon device 12 having the article storage box 12a is configured to be movable also below the tabletop 2 (see FIGS. 1 and 3).
[0018]
