Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a folding structure of legs in a wet edge, a pedestal, or the like.

[Prior art and its problems]

In the past, there was no idea to fold a wet edge leg. However, since the wet edge is provided in the lower part of the door facing the garden or terrace, it is rarely used in the winter season and rather interferes with snow removal work, so it is preferable to fold the legs. In this case, if the legs can be folded and the wet edge body composed of a horizontal plate can be lifted and held upright, it can be used as a snow fence in a cold region.

By the way, as a chair that can be lifted and folded during work so that it does not interfere with work, a notch is provided on a substantially vertical mounting plate so that one end of the seat frame hooks upward, and at the upper part and the seat frame above the notch of the mounting plate. A chair provided with a cane-shaped short support plate pivoted at both ends and a cane-shaped long support plate pivoted at both ends below the notch of the mounting plate and the sill frame (Jitsuko Sho 52-46249). However, since this chair has a structure without legs, folding of the legs is not a problem. However, the mounting plate of this chair is a horizontal plate, and
When considering a wet edge with a stool as a leg material, and a leg folding structure in a chair, etc., the stool has a structure that rotates to the side of the short support plate as described above. Since the mounting plate cannot be securely and firmly supported, there is a disadvantage that it cannot be applied as it is as a leg folding structure.

In addition, since there was no pedestal capable of folding and storing legs, there was a drawback that it took a lot of space to put away things in the shed etc. in winter. Therefore, it is conceivable to fold the legs of the pedestal like an indoor table that can fold the legs, but in the conventional indoor table, the one that can easily fold the legs has weak strength and tends to wobble, so if strength is needed, Since it is necessary to fix the legs using bolts and screws, this folding structure cannot be directly applied to the pedestal, which is inevitable.

[Purpose of device]

The present invention has been made to solve the above problems, and an object thereof is to make it possible to fold and store legs easily and to obtain sufficient supporting strength when the legs are used. And

[Means for solving problems]

The folding structure of the leg according to the present invention is a long-sized member in which both ends of the leg member are pivotally attached to the side face of the leg member at the folding direction side of the leg member attached to the lower portion of the horizontal plate at a substantially right angle. A cane member is provided, and a short cane member having both ends pivotally attached to the side surface of the leg member upper end and the lower end of the horizontal plate is provided on the side opposite to the folding direction side of the leg member. It is what

When the heat insulating coating layer 34 is formed by pasting a laminate, the surface of the horizontal plate 1 does not become too hot, and the inner surface of the support frame 3 exposed at the lower part of the horizontal plate 1 and the lower surface of the edge plate 4 are exposed. Since the heat is radiated, the wet edge does not become too hot even under hot weather, and it is comfortable to use, which is preferable.
It is preferable that a hole for heat dissipation is formed in the heat dissipation part below the horizontal plate 1 as required. In addition, although the example of the wet edge has been described in this embodiment, it can also be applied to a curb or the like as shown in FIGS. 9 to 11. In this case, the horizontal plate 1 (the main body of the frame)
Two pairs of leg members 11 are provided on the lower portions of both ends of the horizontal plate 1, and the leg members 11 are folded toward the center of the horizontal plate 1.

[Action]

When using it, remove the bolt 27 screwed into the screw hole 6 provided in the receiving beam 2 through the screw through hole 16 provided in the middle beam 15, and then rotate the horizontal plate 1 to a substantially horizontal position. For example, as shown by the phantom line in FIG. 5, the long cane member 22 and the short cane member 17 are both rotated clockwise about the pins 26 and 21 by the weight of the leg member 11, respectively. 11 naturally descends from within the horizontal plate 1 and the cane material 1
Due to the difference in the lengths of 7 and 22, the leg material 11 is inclined. Therefore, by pressing the lower end of the leg material 11 to the side opposite to the folding direction (the right side in the drawing), the leg material 11 is pushed. The pin 24 at the tip of the long cane member 22 is rotated in the direction opposite to the clockwise direction to rotate the short cane member 17 further in the clockwise direction, and then the leg member 11 is lifted.
The upper end of the leg material 11 is brought into contact with the edge body 4 at a substantially right angle via the leg cover 13. Next, the bolt 27 is screwed into the threaded hole 5 provided in the beam receiving member 2 through the threaded hole 14 provided in the leg cover 13, and is tightened by the first-step tightening surface 30 to maintain the standing state of the leg material 11. . The horizontal plate 1 is rotated downward so that the lower end of the leg member 11 is grounded to the ground 32 for use. If necessary, the length of the leg member 11 is adjusted by the adjusting screw 12 so that the horizontal plate 1 becomes substantially horizontal.

At the assembled wet edge, the center line M of the leg material 11 is sandwiched, and the triangle CEA and the triangle BD of which one side overlaps on the line M
E is established, and the upper and middle portions of the leg member 11 are supported by the two cane members 17 and 22 so as not to move in the direction opposite to the folding direction, and the leg member 11 is attached to the edge member 4. The leg member 11 cannot be folded unless the leg member 11 is moved downward at a right angle by assembling by pushing at a right angle.

Therefore, it has sufficient strength when using a wet edge, and
Since it is fixed by the bolts 27, the wet edge sufficiently secures the necessary assembly strength, and a stable wet edge can be obtained.

If you want to fold the legs and use it as a snow fence, use the leg cover 1
If the bolt 27 screwed into the screw hole 5 provided in the beam receiving member 2 through the screw hole 14 provided in 3 is removed, and then the horizontal plate 1 is rotated upward, the leg member 11 becomes long due to its own weight. The cane member 22 rotates clockwise around the pin 26, the short cane member 17 rotates counterclockwise around the pin 21, and the weight G of the leg member 11 is long. Since the leg member 11 is located at the lower end side of the leg member 11 from the member mounting position (pin 24), the leg member 11 rotates in the clockwise direction around the pin 24 while being supported by the cane members 17 and 22, which is different from the above. The reverse movement causes the legs to fold naturally. Finally, after the leg member 11 is folded into the horizontal plate 1 so as to abut the lower surface of the beam member 2, the middle bar 15
The bolt 27 is screwed into the threaded hole 6 provided in the beam receiving member 2 through the threaded hole 16 provided in the above, and is tightened at the second-step tightening surface 31 to maintain the folded state of the leg material 11, and not shown. The horizontal plate 1 is fixed to the standing position by the fixing tool.

The horizontal plate 1 in this state can be used as a snow fence.

[Effect of device]

As described above, according to the present invention, it is possible to easily and quickly assemble or fold the leg members by the link mechanism by attaching two cane members having different lengths, and to obtain a strong and stable wet edge and the like. it can.
