Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a top plate supporting beam fixing device for a bipedal folding table.

[0002]

[Prior art]

 Conventionally, a two-legged type in which the upper parts of the left and right leg cylinders are connected by a top plate supporting beam, and the table top plate is pivotally mounted on the side of the top plate supporting beam so that the table top plate can be pivotally folded horizontally and vertically. Folding tables are known.

[0003]

[Problems to be solved by the device]

 However, in this type of bipedal folding table, it is difficult to firmly and firmly connect and fix the left and right leg cylinder rods by the top plate support beam, so that the top plate support beam is shaken or rattled by the load. Was inevitable, and the instability of the table and the deterioration of strength were inevitable. An object of the present invention is to provide a stable top plate supporting beam fixing device that suppresses the wobbling and rattling of the top plate supporting beam and is free from rattling due to a load.

[0004]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above-mentioned problems, and its gist is to provide a cylindrical top plate support having support plates for pivotally supporting the top plate at the upper end on the left and right sides respectively. A beam, a fitting having nut portions fitted in both end portions of the top plate supporting beam, and a protruding cylinder portion projectingly formed on the inner surface of a fixed plate having projections protruding above and below the outer surface, respectively. It consists of a joint joint and a leg rod with an external hole for a set screw.The upper and lower protrusions are fitted inside and the plate is overlapped with the inner wall so that the fitting joint fits on the leg rod. The top end of the top plate supporting beam is tightly fitted into the protrusion of the fitting joint, and screwed into the nut part of the fitting of the top plate supporting beam through the inner wall of the leg cylinder rod and the fixed plate of the fitting joint. This is a top plate support beam fixing device for a bipedal folding table that is fixed by screwing the set screw. Next, embodiments of the present invention will be described in detail with reference to the drawings.

【Example】

 First of all, 1 is a rectangular cylindrical top plate support beam in which support plates 4 for pivotally supporting the table top plate 5 at the upper end are provided on both left and right sides. A tray-shaped fitting 17 having upper and lower nut portions 18, 18 is integrally fitted in the cylinders at both ends of the top plate supporting beam 1. Reference numeral 6 is a substrate integrally provided on each of the left and right sides between the front and rear base rods 8, 8 attached to the front and rear of the lower surface of the top plate 5. A substrate 6 of a table top plate 5 is rotatably supported by a pivot shaft 7 at the upper ends of both side support plates 4 of the top plate support beam 1. Next, reference numeral 12 is a fitting joint in which a projecting cylindrical portion 16 is formed on the inner surface of a fixed plate 13 in which projections 14 are formed on the upper and lower sides of the outer surface, and is made of, for example, a plastic material containing glass fibers. There is. In addition, screw holes 15 and 15 are provided above and below the plate 13. Further, 2 is a leg cylinder rod having a leg seat rod 3 at the lower end. In the upper part of the leg rod 2, upper and lower projection holes 9 and 9 and upper and lower screw through holes 10 and 10 corresponding to the upper and lower screw through holes 15 and 15 are formed on the inner wall 2a side, and upper and lower screw through holes 10 and 10 are formed on the outer wall 2b side. Insertion holes 11, 11 for the set screw 19 are provided respectively. Therefore, first, the upper and lower protrusions 14 and 14 are fitted into the inside through the upper and lower protrusion holes 9 and 9, respectively, so that the fixed plate 13 is superposed on the inner wall 2a, and the fitting joint 12 is fitted to the leg cylinder rod 2. The top end of the top plate supporting beam 1 is tightly fitted into the protrusion 16 of the fitting joint 12, and the fitting 17 of the top plate supporting beam 1 is inserted through the inner wall 2a of the leg rod 2 and the fixed plate 13 of the fitting joint 12. This is a top plate supporting beam fixing device for a bipod folding table, which is fixed by screwing a set screw 19 screwed into a nut part 18. Further, a lever 20 is pivotally attached to a base plate 6 on the lower surface of the top plate 5 with a torsion coil spring 22 interposed therebetween by a support shaft 21, and an engaging fitting 26 at a tip end portion of the lever 20 has an arc hole 23 at an upper portion of the support plate 4. Is engaged in. Therefore, the lever 20 can be rotated to fold the top plate 5 from the horizontal state of FIG. 3 to the vertical state of FIG. 4 and from the vertical state of FIG. 4 to the horizontal state of FIG. . Reference numeral 24 is a shelf body that is supported by a stay 25.

[0006]

The top plate supporting beam fixing device of the present invention is as described above, and the top plate supporting beam 1 and the leg cylinder rod 2 are formed by using the fitting joint 12 and screwing the set screw 19. Can be combined reasonably and powerfully. Further, the shake of the top plate support beam 1 is suppressed and eliminated, stability and strength are increased, and rattling due to load does not occur.
