Description

[Detailed Description of the Invention] Industrial Field of Use This invention relates to a desk used for office purposes, etc., and particularly to a desk with a sub-top plate that allows the desk area to be expanded as necessary.

Conventional technology and its problems Side cabinets and side desks are used to increase the desk area used for office work in offices, etc., but once these are installed, they cannot be easily moved or removed when not needed. Since this cannot be done, there is a problem that it becomes a hindrance and reduces the indoor space.

Means to Solve the Problems This invention was made to solve the above-mentioned conventional problems.The desk area of the desk itself can be expanded when necessary by using the sub-top plate, and the sub-top plate can be used when it is not needed. can be reduced to the original desk space when stored.
Furthermore, the present invention provides a desk with a secondary top plate that is extremely easy to operate.

That is, in the desk with a sub-top plate according to this invention, for the above purpose, the sub-top plate is pivotally attached at one end side to the lower surface of the top plate of the desk main body, and the cabinet is pivoted on the lower surface of the other end side of the sub-top plate. freely pivoted,
The sub-top plate is configured to be rotatable with the cabinet around one end thereof between a position where it is stored under the top plate of the main body and a position where it protrudes forward in an L-shape from the main body. It is what it is.

Embodiments Hereinafter, this invention will be explained based on illustrated embodiments.

In the figure, 1 is the desk body, and the top plate 2
, left and right side plates 3, 3 that support this, and a curtain plate 4 that shields the rear side of the desk are integrated.
Reference numeral 5 denotes a substantially rectangular sub-top plate sized to fit under the top plate 2 of the desk main body 1, and one end thereof is pivotally connected to the lower surface of the top plate 2 so as to be rotatable in a horizontal plane. Reference numeral 6 denotes a substantially vertical box-shaped cabinet with three drawers 6a... and a directional caster 7 attached to the bottom, and a sub-top plate 5 at the top.
It is pivotally connected to the lower surface of the other end, that is, the free end, so as to be rotatable in a horizontal plane.

Two circular holes 8, 8 of the same diameter are opened along the width direction on one end side of the sub-top plate 5, and in one of the circular holes 8, a sliding plate having an L-shaped cross section is formed on the opening edges on both sides. A metal connector 10 having a short cylindrical shape with a bottom and an outward flange 10a on the opening side is inserted through the plastic ring 9 with its bottom wall 10b facing upward.
The flange portion 10a engages with the lower opening edge of the circular hole 8. Therefore, the bottom wall portion 1 of the connector 10
Bolt holes 11, 11... are bored in 0b, and the bottom wall part 10b is superimposed on the lower surface of the top plate 2.
By screwing mounting bolts 12a through the respective bolt holes 11 into nuts 12b embedded in the lower surface of the top plate 2, the top plate 2 and the sub-top plate 5 are pivotally connected so as to be relatively rotatable. Incidentally, each circular hole 8 of the sub-top plate 5 has recessed portions 8a, 8a formed at radially opposite positions, and each slippery resin ring 9 has a locking protrusion (not shown) provided therein. Relative rotation with respect to the sub-top plate 5 is prevented by the engagement of the recesses 8a, 8a. Also, both corner portions 5a, 5a on one end side of the sub-top plate 5
are formed in a rounded shape centered on the circular hole 8 located close to each other.

On the other hand, the cabinet 6 has both side plates 6b, 6b protruding upward, and a horizontal mounting plate 13 is installed between these protruding parts via bolts 14, 14, etc. It is pivotally connected to the center of the lower surface of the other end side of the sub-top plate 5 by a connector 15 . Thus, the connector 15 consists of two square metal dish-shaped plates 15a, 15a each having a circular bulge in the center, which are superimposed with the convex sides facing each other with a lubricant resin plate 15b interposed therebetween. The centers are connected by bolts 16a and nuts 16b, and the mounting screws 18 are embedded in the sub-top plate 5 and the horizontal mounting plate 13 through the screw holes 17 drilled in the four corners of each dish-shaped plate 15a. It is designed to be screwed into a nut (not shown) that is attached to the housing. The plate-shaped plates 15a, 15a are relatively rotatable about the bolt 16a using both sides of the slippery resin plate 15b as sliding surfaces.

In the case of the desk having the above structure, as shown in Fig. 2, in normal use, the sub-top plate 5 is stored under the top plate 2 of the main body 1 together with the cabinet 6, and the cabinet 6 is stored under the top plate 2 of the main body 1, as shown in FIG. It can be handled in the same way as parts.

On the other hand, when it is necessary to increase the desk area, the sub-top plate 5 and the cabinet 6 can be pulled out together with the top plate 2 and the sub-top plate 5, as shown in FIG.
The sub-top plate 5 is arranged in an L-shape in plan view.
can be used as a desk surface. In this arrangement, the cabinet 6 is rotatable in the horizontal plane with respect to the sub-top plate 5, so the orientation of the cabinet 6 can be freely set for convenience of use. Further, since the sub-top plate 5 is supported on both sides by the main body 1 and the cabinet 6, it can be used in a stable state without wobbling. However, when the sub-top plate 5 becomes unnecessary, it can be replaced with the cabinet 6.
At the same time, it may be rotated in the opposite direction to the above to the storage state shown in FIG.

In addition, the sub-top plate 5 can have its pivoting side on the left side of the main body 1 as shown in the figure, but it can also be placed on the right side of the main body 1 by replacing the connector 10. In the configuration of the above embodiment, since the two circular holes 8 into which the connectors 10 can be fitted are arranged in parallel along the width direction on one end side of the sub-top plate 5, the side to which the top plate 2 is pivoted is the main body. In either case of the left or right side of the main body 1, by utilizing the circular hole 8 located toward the front of the main body 1 for pivoting, it is possible to increase the amount of overhang of the sub-top plate 5.

Note that the pivot structure between the top plate 2 and the sub-top plate 5, as well as between the sub-top plate 5 and the cabinet 6, can be modified in various ways other than those in the embodiment.

Effects of the invention The desk with a sub-top plate according to this invention has a position where the sub-top plate is housed under the top plate of the desk main body with the cabinet pivotally attached to the other end side, and the sub-top plate is placed in a position where the sub-top plate is centered at one end side and is moved forward. Since it can be rotated freely between the position where it protrudes in the shape of a letter, when it is necessary to widen the desk area, the secondary top plate can be pulled out and extended and used as a desk surface. Since the sub-top plate is supported by the cabinet and the top plate of the main body, it has excellent stability, and the direction of the cabinet can be set as desired.In addition, when the above is not necessary, the sub-top plate can be easily attached to the cabinet. It can be returned to the storage position, does not get in the way or narrow the interior space like conventional side cabinets or side desks, is extremely easy to operate, and has a very simple structure. Therefore, it has the advantage of being able to be manufactured at low cost.
