  The opening on the top plate 2 side of the groove portion 14c is closed at the top by the top plate lower surface 2a when the bracket 10 is attached, and the rod-like portion 25b is stably held rotatably by the top plate lower surface 2a and the groove portion 14c. Has been. In this embodiment, the lever holding pieces 26, 26 are fitted in the front and rear two places above the rod-like portion 25b. When the bracket 10 is attached to the top plate 2, the lever member 25 is removed from the groove portion 14c. While being prevented from coming off, it is held so that the rod-like portion 25b after attachment can be rotated more smoothly around the axis.

  As shown in FIGS. 6A and 6B, the extending portion 25c of the lever member 25 rotates the rod-like portion 25b via the locking receiving shaft 32a by the elastic biasing force of the spring member 33. Therefore, the handle portion 25a of the lever member 25 is inclined downward with respect to the horizontal portion 17, and the handle portion 25a is slightly spaced downward from the lower surface 2a of the top plate 2. It has become.

  As shown in FIG. 6 (b), the engaging protrusion 32, which is a locking means, is engaged with the engaging hole 7c in the horizontal use position of the top plate 2, and the locked state of the top plate 2 is maintained. Inadvertent rotation of the top plate 2 is prevented. As shown in FIGS. 6 (a) and 8 (a), when the handle portion 25a of the lever member 25 is operated toward the lower surface 2a side of the top plate 2, as shown in FIG. 7 (a). Then, the extending portion 25c rotates around the rod-like portion 25b, and the locking receiving shaft 32a moves toward the outer left side. Then, as shown in FIG. 7B, the engaging protrusion 32 that has been engaged with the engaging hole 7c is linked via the locking receiving shaft 32a by the extending portion 25c, and the elasticity of the spring member 33 is thereby increased. It moves toward the outer left side against the urging force, and the engagement of the engagement protrusion 32 is released from the engagement hole 7c.

  In this way, the extending portion 25c is linked to the engaging protrusion 32, and the engaging protrusion 32 can be detached from the engaging hole 7c, so that the top plate 2 can be maintained in a locked state with a simple structure. It can be released. Moreover, since the engaging protrusion 32 moves while being slidably guided in the guide groove 20 formed on the inner side surface 11a of the bracket 10, the engagement with the engagement hole 7c can be smoothly performed.

  Only when the engagement between the engagement hole 7c and the engagement protrusion 32 described above is released, the top plate 2 is folded from a horizontal position [see FIG. 1 (a)] to a substantially vertical folding position [FIG. (See (b)), the connecting rod 6 can be turned upward with the connecting rod 6 as an axis, and specifically, as shown in FIG. 8 (b), it is released from the engaging hole 7c. The top plate 2 is folded while being slidably contacted upward and obliquely rearward along the outer surface of the outer plate 7 a of the closing plate 7, as indicated by the two-dot chain line at the inward end of the engaging protrusion 32. When moved to the position [see FIG. 1 (b)], the engaging projection 32 again receives the urging force of the spring member 33, and is engaged with the step 7d at the upper rear end of the outer plate 7a. Return of the plate 2 to the horizontal position is restricted. And the inclination position of the bracket 10 is fixed, and the substantially perpendicular folding position of the top plate 2 is fixed reliably.

  In this way, by engaging the engaging protrusion 32 with the stepped portion 7d formed on the closing plate 7 at the folding position of the top plate 2, the folding position of the top plate 2 can be secured using the closing plate 7. . Moreover, since the engagement protrusion 32 is elastically biased, the engagement state with the engagement hole 7c in the horizontal use position of the top plate 2 and the engagement state with the step portion 7d in the substantially vertical folding position. Can be ensured. In order to return the top plate 2 from the substantially vertical folding position to the horizontal position, the handle portion 25a of the lever member 25 is operated again toward the lower surface 2a side of the top plate 2, and the engaging projection 32 is moved to the outer plate 7a. By removing the top plate 2 from the step 7d and returning the top plate 2 in the horizontal direction, the engaging protrusion 32a is fitted into the engaging hole 7c and returns to the state shown in FIG.

  As shown in FIG. 9, when the top plate is rotated, the arc-shaped portion 16 of the bracket 10 is in sliding contact or close proximity along the arc-shaped cover member 8 provided on the closing plate 7. And the arcuate cover member 8 is exposed at the folding position of the table 1. At this time, the front end of the flange 13 formed on the inner side of the bracket 10 (see FIG. 4) enters the space S formed between the end 6 a of the connecting rod 6 and the leg 3, Further rotation is restricted.

  In the present embodiment, since the rod-like portion 25b of the lever member 25 is supported by the groove portion 14c and the top plate lower surface 2a in the bracket 10, the lever member 25 can be easily attached from the upper portion of the bracket 10, and the rod-like portion. Since a special member for supporting 25b is not required, it is not necessary to provide a complicated support element, and the number of members can be reduced. Moreover, since the rod-like portion 25b is closed by the top plate 2, it is not conspicuous outward and the appearance is good.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. For example, in the above-described embodiment, the engagement hole 7c is formed in the outer plate 7a of the closing plate 7 that covers the upper end portion 3a of the leg 3, so that the bracket 10 is engaged when the bracket 10 is axially attached to the connecting rod 6. Although it is preferable because the alignment between the mating protrusion 32 and the engagement hole 7c can be easily performed, the present invention is not limited to this, and the outside of the upper end portion 3a of the leg 3 is not limited to using the closing plate 7. An engagement hole that can engage with the engagement protrusion 32 may be formed directly on the side surface.

  Moreover, in the said Example, the lever holding piece 26 is inserted above the rod-shaped part 25b, the removal of the lever member 25 from the bracket 10 is prevented, and the convenience of the operation | work which attaches to the top plate 2 is improved. However, the present invention is not limited to this.
