These caps are formed to have substantially the same shape as the plan shape of the leg body 16, and end caps capable of closing the upper and lower ends of the columns 20 and 20. 25, 25 and bent pieces 21, 23
And a plurality of screw holes 27 are formed in the caps 26, 26 so that screws 28, 29 or bolts can be screwed.

The distance D between the end caps 25, 25,
That is, the width of the recess 14a or the facing distance between the pillars 20, 20 is configured to be wider than the outer surface distance E of the support frames 2, 2.
Also, the inner surface of the end cap 25, 25 or the pedestal 20,
The inner surface of 20 projects more inward than the inner surface of the edge caps 26, 26 or the surface of the inner panel 16, and the projection amount F, that is, the depth of the recess 14 a is set to be slightly smaller than the height G of the support frame 2. Thus, the support frames 2 and 2 can be accommodated between the pillars 20 and 20 when the legs 15 and 15 are folded. In the figure, reference numeral 30 denotes a flange projecting from the peripheral edges of the caps 18 and 19, which can be fitted to the upper and lower edges of the leg body 16 and the inner plate 17.

The table thus constructed comprises a top plate 1, a pair of support frames 2, a pair of legs 18 and a lock mechanism for the legs 18, of which the support frame 2 cuts a steel pipe into a predetermined length. The through hole 5, the guide groove 8 and the long groove 12 are formed at a predetermined position of the end portion, to manufacture. Further, the lock mechanism is formed by pressing a steel plate to integrally form the slider 9, the lock fitting 10 and the locking piece 14, and the pair of lock fittings 10 and 10 are arranged to face each other, and the lock lever 11 is inserted into them. Weld and manufacture with.

The leg 18 is formed by press-forming a steel plate to form the leg body 1
6 and the inner panel 17 are manufactured, a synthetic resin film is adhered to the surface of the leg body 16, a pair of brackets 4 and 4 are welded at predetermined positions on the surface of the panel 17, and a reinforcing member is fixed to the back surface. . The caps 18 and 19 are integrally molded by resin molding. Therefore, the material cost is reduced as compared with the conventional wooden legs, and the legs can be manufactured at a low cost.

Next, when assembling the legs 15, the pedestal 2
The inner panel 17 is fitted between 0 and 20, and the bent pieces 23 and 23 are superposed on the inside of the bent pieces 21 and 21.
While maintaining this state, the caps 18 and 19 are fitted to the upper and lower ends of the leg body 16, the end caps 25 and 25 are fitted to the pedestals 20 and 20, and the edge caps 26 and
When 26 is fitted in the bending pieces 21 and 23, screws 28 and 29 are screwed into the screw holes 24 from the screw holes 27 and 22 to integrally connect the leg body 16, the inner panel 17, and the caps 18 and 19. Good.

When assembling a table with these components, for example, the bending pieces 4a, 4a of the bracket 4 are fitted into both ends of the supporting frames 2, 2 and the bending pieces 4a, 4a are fitted.
Then, the pin 3 is inserted into the pin holes 6 and 5 of the support frame 2 to rotatably connect the legs 15 and 15. After that, holding the assembled lock mechanism, insert both ends of the lock lever 11 into the long grooves 12, 12 on the inner surface of the support frames 2, 2 and insert the tip ends of the sliders 9, 9 into the guide grooves 8, 8. ,
Hang both ends of the spring 13 on the pin 3 and the lock lever 11. In this way, the support frames 2 and 2 in which the legs 15 and 15 and the lock mechanism are assembled may be attached to a predetermined position on the lower surface of the top plate 1.

In the table thus assembled, the legs 15 and 15 are vertically erected during use, and the end caps 25 and 25 of the cap 19 are installed on the floor surface. This situation is as shown in FIGS. 1 and 2. Since the flat grounding surfaces of the end caps 25, 25 are in contact with the floor surface, the standing posture of the table is stable and the legs 15, 15 are wall-shaped. Since it is exhibited, the texture is more profound than the conventional legs with exposed steel frames, and the sense of quality is enhanced.

In such a use, as shown in FIGS.
The upper cap 18 engages with the lower surface of the top plate 1, the sliders 9 and 9 are positioned in the middle of the guide grooves 8 and 8, and the notches 7 and 7 of the brackets 4 and 4 engage with the sliders 9 and 9 to form the bracket. Since the rotation of 4 and 4 is blocked, the legs 15 and 15 integrated with the brackets 4 and 4 are locked, and the standing posture of the table is maintained. At that time, the convex portions 14a, 14a of the locking piece 14 are engaged with the inner surfaces of the support frames 2, 2, and the piece 14 is positioned parallel to the support frame 2 so that the lock lever 11 is perpendicular to the support frame 2. Position it.

When the legs 15 and 15 are to be folded from such a situation, the grip portion 11a of the lock lever 11 is held,
This is pulled inward against the elasticity of the spring 13. By doing so, the sliders 9 and 9 move together with the lever 11 and simultaneously release the engagement with the notches 7 and 7, so that the brackets 4 and 4 and the legs 15 and 15 can rotate. The lock is released. After that, if the legs 15 and 15 are pushed inward while holding the lock release operation of the lock lever 11, the brackets 4 and 4 rotate inward about the pin 3 and the legs 15 and 15 Together, they are folded like the phantom lines in FIG.

In this case, the lock lever 11 has the grip portion 11
When operated at a position other than a, the lever 11 moves the support frame 2
On the other hand, there is a concern that the sliders 9, 9 that move obliquely and move together may have different displacements on the left and right sides, and the disengagement with the notches 7, 7 cannot be performed at the same time. However, even if the lock lever 11 is operated at a position other than the grip portion 11a, the protrusion 1
Since 4a and 14a engage with the inner surfaces of the support frames 2 and 2 and promote the vertical movement of the lever 11 with respect to the support frames 2 and 2,
Dispel the above concerns.

The legs 15 and 15 rotate 90 ° inward from the standing position, and when the inner panel 16 comes into contact with a stopper (not shown) attached to the lower end of the support frames 2 and 2, the rotation is stopped. Then, it is folded in parallel with the support frame 2. This situation is as shown in FIG. 8, in which the support frames 2 and 2 are located between the pedestals 20 and 20, and the support frames 2 and 2 are partially housed inside the legs 15. Therefore, the storage of the support frames 2 and 2 and the leg 15
Can be folded compactly, and its handling becomes convenient, and the storage space and packing case can be made compact.

After the legs 15 and 15 are folded, the bracket 4 is positioned as shown by the phantom line in FIG. 5, and the slider 9 is engaged with the peripheral surface of the bracket 4 to prevent the bracket 4 from rotating.
Hold 15 folds.

When the leg 15 is erected and rotated from such a situation, the bracket 4 is rotated counterclockwise in FIG. 5 about the pin 3, and the slider 9 engaged with the peripheral surface of the bracket 4 is elastic. It is pushed against and the lock lever 11 moves along with it. Then, when the leg 15 rotates 90 °, the slider 9 engages with the notch 7 and the cap 18
Engages with the lower surface of the top plate 1 to stop rotation, and its standing state is locked.

The notch 7 is worn away over time due to friction with the slider 9, but since the notch 7 is formed in an upwardly tapered shape, the slider 9 gradually moves toward the base of the notch 7 due to abrasion. , The engaging action of both is enabled, and the long-term and reliable locking action of the leg 15 is realized.
