Specifically, the pedestal 11 includes a dome-shaped plate 111 having a hemispherical cross-section, a receiving groove 112 formed on the upper side of the dome-shaped plate, and a coupling groove 113 disposed around the receiving groove. .

As shown, the dome-shaped plate 111 is formed in a hemispherical shape to form an internal space (no reference symbol) at the bottom, and has a convex outer upper surface and a concave inner lower surface and protrudes upward. The internal space limited by the dome-shaped plate 111 provides a space for accommodating the lower end of the support leg and the fastening port of the strap portion, which will be described later, while improving the contact area with the ground.

The receiving groove 112 extends from the outer upper surface of the dome plate 111 toward the inner space defined by the inner lower surface thereof, and is located on the support leg 22 of the chair 2, specifically the front support leg 22a. It may be formed concavely toward the inner space defined by the dome-shaped plate 111 so that the lower end and the lower end of the rear support leg 22b can be inserted. In addition, the receiving groove 112 is formed in a shape corresponding to the lower end of the support leg (22; 22a, 22b), so that the lower end of the support leg can be inserted to be detachable.

Preferably, the receiving groove 112 forms a drain hole 112a at its lowermost end. The drain hole 112a discharges foreign substances such as dirt and sand that have flowed into the receiving groove to the outside, or helps drain moisture such as rainwater that has flowed into the receiving groove to the lower side.

In addition, in the present invention, the end (lowest end) of the receiving groove is located in the inner space of the dome-shaped plate without protruding below the edge of the dome-shaped plate to enable horizontal arrangement of the dome-shaped pedestal 11 on the target ground.

As previously described, the stand 11 may be provided with a coupling groove 113 that helps fasten the strap portion 12. The dome-shaped plate 111 has a receiving groove as shown and forms the above-described coupling groove 113 around the receiving groove.

Through this configuration, the present invention can prevent sinking of the support leg by expanding the surface area of the dome-shaped pedestal that touches the target ground, distributing the user's weight and reducing the pressure applied to the ground.

In addition, the ground fixture 1 for holding according to the present invention may be composed of a pair of dome-shaped pedestals 11 described above and a strap portion 12 disposed between the pair of pedestals 11. .

The strap portion 12 includes a length portion 121 disposed across the front support leg 22a and the rear support leg 22b, and fasteners 122 at both ends of the length portion 121. Equipped with Each fastener 122 is connected to a coupling groove 113 provided in one stand 11 press-fitted to the lower end of the front support leg and the other stand 11 press-fitted to the lower end of the rear support leg. It is concluded. Here, the length of the strap portion can be adjusted to correspond to the gap between the front support leg 22a and the rear support leg 22b, so that the gap between the front support leg and the rear support leg 22b can be kept constant.

Of course, the length portion 121 may employ various types of length adjusters available on the market.

Figure 5 is a longitudinal cross-sectional view schematically showing the base of the ground fixture for support according to the present invention. The pedestal illustrated in FIG. 5 is another modified example of the pedestal illustrated in FIGS. 2 to 4. Since it has a very similar structure except for the configuration of the drain hole, a similar or identical configuration is used to facilitate a clear understanding of the present invention. The explanation will be excluded here.

As previously described, the ground fixture for holding according to the present invention can discharge foreign substances, moisture, etc. to the outside through the drain hole 112a of the receiving groove 112 formed in the dome-shaped pedestal 11.

When the pedestal 11 press-fitted to each of the support legs 22, 22a, and 22b comes into contact with the ground, reverse inflow of dirt or water may occur through the drain hole 112a of the pedestal 11. For this purpose, the present invention may additionally include a flap 114 that opens and closes the drain hole 112a.

As shown, the flap 114 is rotatably disposed on the downstream side of the drain hole 112a, that is, on the discharge side. As a result, the flap is forcibly rotated downward due to the load of dirt or moisture flowing into the receiving groove 112, thereby forcing the drain hole to be opened and easily discharging them to the outside. On the other hand, while the discharge is stopped or By rotating upward through contact (pressure force) with soil or moisture, the drain hole is forcibly closed, thereby reliably blocking their reverse inflow.

Optionally, the flap 114 may be made of a sheet material with flexible elasticity so that it can be opened without power by the load of foreign substances discharged to the outside through the drain hole, and the flap 114 may be made of a sheet material with flexible elasticity to ensure reliable closure of the drain hole. It can be formed in a size larger than the diameter of the hole.

Figure 6 is a view schematically showing another example of the pedestal of the ground fixture for holding according to the present invention. In the present invention, the pedestal 11 includes an annular rim 115 that is elastically deformable along the upstream side of the receiving groove 112, that is, around the inlet side.

As shown, the annular rim 115 is formed in a truncated cone shape with an open cross-sectional area that narrows upward from the upstream side of the receiving groove 112, and may be formed of a stretchable flexible material.

Since the annular rim 115 has flexibility and elasticity, support legs having various outer diameter sizes can be aligned concentrically with the receiving groove 112. In addition, the annular rim 115 can minimize the inflow of foreign substances into the receiving groove 112 by removing foreign substances attached to the outer peripheral surface of the support leg while the lower end of the support leg enters the receiving groove 112.

Figure 7 is a diagram showing an application example of the ground fixture for holding according to the present invention, which shows a support pole (supporting pole) that supports the roof sheet 100 of a tarp installed to extend from a tent, vehicle, etc. at a certain height from the ground. By inserting the dome-shaped pedestal 11 of the ground fixture for support according to the present invention into the lower part of 120), sinking of the support pole can be prevented.

Here, the dome-shaped pedestal 11 may be coupled to the lower end of a long, thin rod that touches the ground according to the user's request.

Figure 8 is a diagram showing a state in which the ground fixture for holding according to the present invention is fitted and coupled to the support leg of the folding table 200. As is widely known, a folding table includes a top plate and support legs supporting the top plate so that it can be easily assembled outdoors for camping or leisure purposes, and the base 11 of the ground fixture according to the present invention is inserted into the lower part of the support leg. Combined, it is possible to prevent sinking of the support legs.

In addition, the ground fixture according to the present invention can also be applied to a foldable extra bed that helps you sleep comfortably while avoiding the cold coming from the floor when sleeping outdoors. In the present invention, as shown in FIG. 9, the base 11 can be coupled and arranged at the lower end of the support leg of the foldable bed 300.

The ground fixture for holding according to the present invention is not limited to the chairs, tents, and cots described above, but can also be applied to the support legs of various items standing in contact with the ground outdoors (e.g., screens, tents, benches, etc.) It is obvious to those skilled in the art that it exists. Moreover, a strap portion 12 (see Figure 1) may be employed between a pair of support legs supporting various items.
