Description

[Detailed Description of the Invention] The present invention relates to a leg device for a stand for hanging a hanging picture, a stand for placing musical scores, and a stand for placing various objects such as musical instruments and flower pots.

In the conventional leg device of this type of stand, the radial base placed on the floor was a welded integral structure that could not be disassembled, so it was not only cumbersome to manufacture;
There were drawbacks such as the bulky packaging when shipping the product.

It is an object of the present invention to overcome these drawbacks and provide a leg device that is inexpensive and easy to manufacture and can be disassembled and packed compactly.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

The stand 1 shown in FIG. 1 is used for teaching by suspending a hanging diagram, and includes a column 2, a radial base 3 placed on the floor, and a hanging diagram attached to the upper end of the pillar 2. It consists of a holding part 4.

As shown in FIGS. 1 and 2, the hanging picture holding section 4 includes a square tube section 6 having a downward opening-shaped slit 5, and a holding horizontal rod 7 inserted into one side of the square tube section 6. On the other hand, the hanging figure 8 has a hanging horizontal member 9 made of plastic, wood, etc. attached to its upper edge, and this hanging horizontal member 9 is inserted into the square tube part 6, and the hanging figure 8 is passed through the slit 5. Hold it so that it hangs downward. In this inserted state, the horizontal member 9 comes into contact with the front vertical wall surface of the horizontal holding rod 7, and is held without wobbling.

Further, in the illustrated example, the column part 2 has a telescopic pipe structure including an inner cylinder 10 to which the hanging picture holding part 4 is fixed at the upper end, and an outer cylinder 11 into which the inner cylinder 10 is inserted so as to be extendable and contractible from above. Reference numeral 12 denotes a knob bolt, which is used to adjust the height of the column 2 by loosening the knob bolt 12 and then tightening it to fix it.

Thus, the pillar portion 2 is vertically erected from the center of the radial base 3, and as shown in FIGS. 3 and 4, the base 3 consists of three identically shaped columns. It has band members 13, 13, 13, and the base end of each is connected to each other in a three-way shape with the whole being substantially planar. Moreover, each of the strips 13 is disposed substantially horizontally as a whole, and vertically erected in the cross section. More specifically, each strip material 13 has its proximal end bent at two points A and B by 30 degrees, so that the angle formed between the distal end side 14 and the remaining portion on the distal end side of the strip material 13 is adjusted. 60 degrees, and the angle between the second side portion 15 and the remaining portion on the tip side is 30 degrees, and the fasteners 1 such as bolts are brought into contact with each other in a three-pronged manner as shown in Fig. 3.
6... to form a radial-shaped base 3 having a center angle of 120 degrees when viewed from above.

Moreover, by tightening the fasteners 16..., the second side 1
5, 15, and 15 form an equilateral triangle, and side surfaces 17, 17, and 17 of the equilateral triangle are crimped to the outer circumferential surface of the lower end 2a of the column portion 2 as shown by arrows P. When the three strips 13, 13, 13, which can be disassembled and assembled freely, are tightened and assembled using the fasteners 16..., the lower end outer peripheral surface of the outer cylinder 11 of the column part 2 is crimped in a hugging manner. , the pillar portion 2 and the base 3 are connected and supported.

In addition, in FIG.
is drilled and a bolt is screwed into the fastener 16, but it is also preferable that the screw hole 18 is simply a hole and the fastener 16 is connected by a bolt and nut. It is also preferable to attach elastic mounting devices 19 such as rubber feet to each tip of the strips 13 to prevent damage to the floor surface (see FIG. 1). Furthermore, as shown in FIG. 6, a boss part 21 with a screw hole 20 is formed at the tip of the strip material 13, and a bolt part 22 that can be screwed forward and backward is formed in the boss part 21.
It is also very preferable to attach a mounting device 19a having a height adjustment mechanism to prevent rattling between the base 3 and the floor surface.

In FIG. 4, an outer flange 23 is integrally provided by welding or the like at a predetermined position by a predetermined distance from the lower end surface of the column 2, and the lower surface of this outer flange 23 is placed on the upper surface of the base 3. Abuts on position. Further, a nut member 25 having a screw hole 24 is fixed by welding or the like inside the lower end of the column 2 made of pipe material. Reference numeral 26 denotes a clamping washer, and by inserting a fastener 27 such as a bolt into the hole of this washer 26 and tightening it into the screw hole 24, the upper outer flange 23 and this washer 2 are connected.
At 6, the center portion of the base 3 is pressed and held from above and below.

Next, as in another embodiment shown in FIG.
It is also possible to curve the proximal ends of each of the three strips 13 so as to swing about 60 degrees, and to connect them in a three-way shape in a manner that can be disassembled and assembled freely. At this time, the side surface 17 of the curved side part 28 is elastically pressed in the direction of arrow P to the outer peripheral surface of the lower end 2a of the column part 2 in the form of a leaf spring, and can be connected without wobbling even after long-term use.

It goes without saying that the stand may be used for various purposes other than the one used for hanging pictures as shown in FIGS. 1 and 2. Further, the column portion 2 may also be freely formed into a non-retractable type.

According to the illustrated embodiment of the present invention, it can be manufactured by simply bending the strip material 13 at two locations A and B as shown in FIG. There are advantages. Furthermore, as shown in FIG. 4, since the base 3 is held between the outer flange 23 and the washer 26 in a sandwiched manner from above and below, a synergistic effect with the pressure bonding force in the direction of the arrow P in FIG. 3 or 5 is obtained. This has resulted in an extremely strong connection.

As described above, the present device has a radial base 3 placed on a floor surface and a column 2 erected vertically from the center of the base 3. The radial base 3 is formed by bending or curving the base ends of three identical strips 13, 13, 13 and connecting them with fasteners 16 in a triskelion shape that can be disassembled and assembled freely. Furthermore, by fastening the fasteners 16, the side surface 17 of the base end of each strip 13 is pressed against the outer circumferential surface of the lower end 2a of the column 2, and the lower end 2a of the column 2 is fixed to the radial base 3.
Since the stand is supported by the leg device connected to the
The product can be packed in a compact disassembled state when shipped, and can be easily and quickly assembled on-site. Moreover, it has the advantage of being strong and rigid.
Furthermore, the base 3 can be easily manufactured mainly from three strips, and costs can also be reduced.
