DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a folding table with shelves according to the present invention will be described with reference to the drawings. FIG. 1 shows it in an assembled state and FIG. 2 shows it in a folded state. Figure 1
In, the foldable cross legs 2 are attached to the back surface side of the square top plate 1. The crossed leg 2 includes a pair of left and right front legs 3 and a rear leg 4. The left and right front legs 3 are integrally connected at their upper end portions 3a to each other to form a gate shape. The left and right rear legs 4 are also integrally formed by connecting the uppermost end portions 4a to each other to form a gate shape, but are formed to be longer in the up-down direction than the front legs 3.

The front leg 3 and the rear leg 4 are made to intersect each other in an X shape so that the front leg 3 is inside the rear leg 4 and the lower ends of both legs 3 and 4 are aligned with each other. It is pivotally supported by a pivot 5 made of rivets and the like. In order to attach the front and rear legs 3 and 4 to the top plate 1, the front leg receiving portion 6 is fixed to the front of the back surface of the top plate 1, and the upper end portion 3a of the front leg 3 is detachably engaged with the front leg receiving portion 6. . The front leg receiving portion 6 is formed of, for example, an elastic plastic or metal plate into a generally Z-shaped cross section,
By being fixed to the back surface of the top plate 1, a rearward-facing receiving opening 7 that is narrower than the diameter of the upper end portion 3a and is freely deformable, and an engagement groove 8 having a diameter substantially the same as the diameter of the upper end portion 3a. And (see FIG. 2). The upper end portion 3a of the front leg 3 is engaged with and disengaged from the engagement groove 8 through elastic deformation of the receiving port 7.

The left and right rear legs 4 intersect their respective upper portions with the rear portions of the left and right side portions 1a and 1b of the top plate 1, and the left and right intersecting portions are pivotally supported by a pivot 9. With
The extension head 4b is formed by extending further above the intersection with the top plate 1. When the rear leg 4 and the side rear of the top plate 1 are pivotally supported, a pivot support metal fitting 10 having an L-shaped cross section is prepared, and the piece 10a constituting the L shape of the pivot support metal support 10 is a side portion of the top board 1. The other piece 10b is superposed and fixed on the back surface of the top plate 1 so as to be flush with the rear plate 4, and the rear leg 4 is crossed on the surface of the one piece 10a, and the crossing portion is pivotally supported by the pivot 9. The pivot point of the pivot 9 is shifted downward from the back surface of the top plate 1 by about ½ of the diameter of the rear leg 4 (see arrow x in FIG. 2). The dimension D from the pivot 9 to the rear end of the top plate 1 and the dimension E from the cross-sectional center of the uppermost end 4a to the front end of the shelf 12 are added together to determine the cross-sectional center of the pivot 9 from the uppermost end 4a. If it is set to be smaller than the dimension F up to, the surfaces of the top plate 1 and the shelf 12 become substantially flush when folded as shown in FIG.

The shelf 12 made of a flat plate or net is horizontally supported by the stay 11 and the extension head 4b of the rear leg 4 so as to be foldable. That is, the rear of the back surface of the shelf 12 is pivotally supported by the extension head 4b with a stopper 13 having a cross section of Ω shape so that the extension head 4b can be vertically rotated around its uppermost end 4a.
If the stoppers 13 are attached to the shelf 12 so as to be positioned at the left and right ends of the straight line portion of the uppermost end 4a, the uppermost end 4a of the shelf 12 will be described.
Left and right movement on the top can be prevented. The stay 11 is formed in a gate shape as a whole, and the upper end portions 11a and 11a of the left and right arm portions 11b and 11b are integrally connected to each other. The lower ends of the left and right arms 11b and 11b are attached to the left and right extension heads 4b and 4
It is made to intersect with each middle part of b, and this intersection part is connected to the axis 1
Pivot at 4. The upper end portion 11a of the stay 11 is detachably engaged with a stay receiving portion 15 provided on the front side of the back surface of the shelf 12.
The stay receiving portion 15 is formed, for example, in a Z-shape in cross section, and is fixed to the back surface of the shelf 12 so as to be slightly wider than the diameter of the upper end portion 11a between the back surface and the back surface of the shelf 12, and the rearward opening engaging groove. 16 is formed. Upper end 11 of stay 11
a engages with the engagement groove 16 from the rear side thereof. In this engaged state, the shelf 12 is set to be horizontally supported above the front of the top plate 1.

When using the table with shelves thus constructed, as shown in FIG. 1, the front leg 3 and the rear leg 4 are used.
Is opened and the upper end portion 3a of the front leg 3 is engaged with the receiving groove 7 of the front leg receiving portion 6 on the back surface of the top plate 1 into the engaging groove 8, the opening movement of the front leg 3 is restricted by the front leg receiving portion 6. , The top plate 1 is the front and rear legs 3.
It is supported horizontally at 4. By rotating the shelf 12 around the uppermost end portion 4a so that it is in a horizontal posture and rotating the upper end portion 11a of the stay 11 around the pivot 14 backward (in the direction of arrow C in FIG. 1), the upper end portion of the stay 11 is rotated. 1
1a engages in the engagement groove 16 of the stay receiving portion 15 on the back surface of the shelf 12, and this engagement ensures that the shelf 12 is supported horizontally and stably above the front surface of the top plate 1 horizontally. Therefore, for example, when this table is used for a word processing desk, the reference materials for creating and editing documents are stored on the shelf 12
It can be widely used and is easy to use by simply placing it on the tabletop and placing word processing on the top plate 1. Other,
When it is used as an ironing work table, by placing a water spray on the shelf 12, the top plate 1 can be fully used for ironing and the work becomes easy.

After use, the upper end 3a of the front leg 3 is closed rearward (in the direction of arrow B in FIG. 1) around the pivot 5 to rotate the upper end 3a of the front leg 3 on the rear surface of the top plate 1. The front leg 3 can be detached from the portion 6, and the front leg 3 can be closed so as to overlap the inner side of the rear leg 4, and the top plate 1 is folded on the front leg 3 in an overlapping state. When the upper end 11a of the stay 11 is rotated rearward (in the direction of arrow C in FIG. 1) about the pivot 14, the front end of the shelf 12 is vertically rotated upward about the uppermost end 4a of the extension head 4b. The upper end portion 11 a of the stay 11 is separated from the stay receiving portion 15 on the back surface of the shelf 12. By this separation, the stay 11 can be folded compactly in a plane as shown in FIG. 2 so that the stay 11 overlaps the inside of the extension head 4b and the shelf 12 overlaps the extension head 4b.

When the intersection of the rear side of the rear leg 4 and the side portion of the top plate 1 is pivotally supported by the pivot 9, the rear leg 4 is placed on the side portion of the top plate 1 without using the pivot support metal fitting 10. It is also possible to directly intersect with each other and to pivot the intersection with the pivot 9. However, as in the above-described embodiment, the front leg 3 is located inside the rear leg 4, and the pivot point by the pivot 9 is displaced downward from the back surface of the top plate 1 by about 1/2 of the diameter of the rear leg 4. It is preferable that the top plate 1 is pivotally supported on the front and rear legs 3 and 4 as shown in FIG.

In the above embodiment, the left and right front legs 3 are formed in a gate shape in which the upper end portions 3a of the left and right front legs 3 are integrally connected.
Alternatively, the upper end portion 3a of the left front leg 3 and the upper end portion 3a of the right front leg 3 may be separated and engaged with the front leg receiving portion 6 on the back surface of the top plate 1 in a detachable manner. Good. Similarly, the left and right rear legs 4 are also formed in a gate shape in which the uppermost ends 4a thereof are integrally connected, but instead of this, the uppermost end 4a of the left rear leg 4 and the right rear leg 4a are formed. Alternatively, the uppermost ends 4a of the legs 4 may be separated from each other, and the legs 4 may be rotatably supported by the stoppers 13 on the back surface of the shelf 12, respectively. Similarly, in the stay 11 as well, the upper end portions 11a of the left and right arm portions 11b are integrally connected to each other, but instead of this, the upper end portion 11a of the left arm portion 11b and the right arm portion are replaced. It is also possible to separate the upper end portion 11a of 11b and engage the stay receiving portions 15 on the back surface of the shelf 12 in a detachable manner.

[0015]

The uppermost end 4a of the extension head 4b of the rear leg 4 is obtained.
Is rotatably supported at the rear of the back surface of the shelf 12 so that the shelf 12 can be vertically rotated around the uppermost end 4a, and the stay 11 is pivotally supported at its lower end side to the middle portion of the extension head 4b by a pivot 14. The upper end 11a is detachably engaged with the stay receiving portion 15 provided on the front side of the back surface of the shelf 12. Therefore, together with the foldable front and rear legs 3 and 4 and the top plate 1, the shelf 12 can also be folded in a plane along with the top plate 1, and even if it has a shelf, the whole can be compactly folded and packed and carried. It is convenient for storage and storage. Since the extension head 4b for supporting the shelf 12 and the rear leg 4 for supporting the top plate 1 have a single structure in which both are integrally continuous, the number of steps for assembling the table and the number of members can be reduced accordingly. This is advantageous because it can be easily assembled and can be manufactured at low cost.
