Abstract

PROBLEM TO BE SOLVED: To support a pole without looseness by overlapping a plurality of blocks in a fitting state with each other to moderately decenter or skew axial cores of receiving holes of blocks to a fitly axial core of the blocks. SOLUTION: Receiving holes 3 of both blocks 1a, 1b are formed on receiving holes (c) of at a moderately eccentric distance E from fitly axial cores C of fitly protruding part 2a, 2b. Insertion of a pole P of the maximum diameter is allowed when both blocks 1a, 1b are overlapped in a state that axial cores (c) of receiving holes are corresponded. Use of the pole P of the minimum diameter is allowed when both blocks 1a, 1b are overlapped in a state that the axial cores (c) of receiving holes are parted from each other in an opposite direction. Accordingly, an effective hole size of the receiving hole can be easily changed, and the pole of a different diameter can be fixedly leant on the blocks by overlapping a plurality of blocks in the fitting state with each other to change an overlapping phase for moderately decentering the axial cores of the receiving holes to a fitly axial core.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pole support suitable for setting a flag, a flag, etc., and more particularly, to a block-shaped support for inserting a base of a pole, such as a flagpole or a flagpole, to lean against the pole. It relates to a support base.

[0002]

2. Description of the Related Art When a flag or a flag is installed, a trapezoidal concrete block provided with a receiving hole adapted to insert a base near a lower end of a flag stick or a flag pole (hereinafter simply referred to as a pole) is fixed. Place the base of the pole on the pole, and place a flag or flag on the pole, and if the pole has a large diameter and rattle, wedge it into the gap. ing.

[0003]

The diameter of the pole varies in size, and the diameter of the receiving hole formed in the support base is usually manufactured so as to adapt to the large-diameter pole. When manufacturing a support stand dedicated to poles, not only costs are high in various aspects such as molding dies, forming work, storage, transportation, etc., but also consumers have multiple types of support stands and use them. There are disadvantages and inconveniences such as the need to perform

It is an object of the present invention to provide a support base capable of supporting a pole having various diameters with a simple structure, without any backlash. Is to do.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a structure in which a plurality of blocks are stacked in a mutually fitted state, and a receiving axis is aligned with a fitting axis. The present invention is characterized in that the hole is appropriately eccentric or skewed so that the effective hole diameter of the receiving hole can be changed by changing the phase of stacking.

In the case where the axes of the receiving holes in a plurality of stacked blocks coincide with each other, the receiving holes also coincide with each other to form a receiving hole having the maximum diameter. The effective hole diameter of the receiving hole is formed to be the smallest in contact with the stepped or bent state, and the effective hole diameter is adjusted to a desired size if the deviation of the receiving hole axis is a moderate intermediate position. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

As a support to which the present invention is applied, for example, as shown in FIGS. 1 and 2, two large and small blocks 1a and 1b each having a substantially conical outer shape are provided above the large block 1a. In addition to allowing the small blocks 1b to be stacked, a mating structure 2 having an uneven relationship is formed at the opposing surface of the blocks 1a and 1b. In the illustrated embodiment, the large blocks 1a are used. Forming a circular fitting projection 2a on the upper surface of
On the lower surface of the small block 1b, circular fitting concave portions 2b corresponding to the fitting convex portions 2a are formed.
a and a fitting recess 2b to form a rotatable fitting structure 2 and a vertical receiving hole 3 adapted to receive the pole P is formed at a substantially central portion between the blocks 1a and 1b. It is appropriate to adopt it.

As a special configuration of the present invention for the above type, for example, as shown in FIGS.
The receiving hole 3 of 1b is formed at a receiving axis c which is separated from the fitting axis C of the fitting projections 2a, 2b by an appropriate eccentric distance E (for example, 3 mm). , 1b are stacked so that the respective receiving hole axes c coincide with each other, as shown in FIG. 2, so as to accommodate the insertion of the pole P having the maximum diameter. When stacked in a state of being separated from each other in the opposite direction, it is adapted to use a pole P having a minimum diameter as shown in FIG. By stacking the small blocks 1b appropriately (turning them appropriately), it is possible to adapt to the use of the poles P having an intermediate diameter.

It is convenient for transportation and handling to form a groove 4 in the bottom surface of both blocks 1a and 1b in the diameter direction for convenience of transportation and handling, and the diameter of the receiving hole 3 substantially matches the diameter of the pole P. In this case, the blocks 1a and 1b can be used alone without being stacked.

As shown in FIG. 4, the receiving hole 3 is provided slightly obliquely with respect to the fitting structure 2 so as to be separated from the fitting structure 2, that is, the bottom surface of the large block 1a.
Each receiving hole axis c with the top surface of the small block 1b is
By matching or "shifting" according to the phase relationship between the two blocks 1a and 1b, it is possible to adapt to the leaning installation of the pole P from a large diameter to a small diameter as in the above-described embodiment.

The shape of the receiving hole 3 is not limited to a circle, but may be other shapes such as a polygon such as a triangle, a quadrangle, a pentagon, and a hexagon, or an irregular shape close to the polygon. Naturally, the number of supporting contact portions can be increased to stably support, and the outer shapes of both blocks 1a and 1b are not limited to a circular shape, but can adopt other shapes.

In the embodiment shown in the drawings, the case of using two layers is shown. However, it is needless to say that three or more layers may be used, and other materials of the blocks 1a and 1b may be used. Although concrete is most suitable, various materials and configurations such as resin concrete, metal, and other composite structures can be adopted, and it suffices that the weight is large and the weather resistance is sufficient.

The present invention can be used as a pole support similar to the above, such as a fence post, a sign post, a clothesline post, etc. temporarily installed in addition to a flagpole, a flagpole, etc. is there.

[0015]

As described above, according to the present invention, the following effects can be obtained.

A plurality of blocks are stacked in a mutually fitted state, and the receiving hole axis is appropriately decentered with respect to the fitting axis. By changing the phase, the effective hole diameter of the receiving hole can be easily changed, and it is possible to adapt to the fixed leaning of poles having different diameters.

A plurality of blocks are stacked in a mutually fitted state, and the receiving hole axis is skewed moderately with respect to the fitting axis. By changing the phase of the stack, the effective hole diameter of the receiving hole can be easily changed, and it is possible to adapt to the fixed leaning of poles having different diameters.

When the receiving hole is formed in a polygonal shape, the contact portion between the receiving hole and the pole is increased as compared with a circular case, so that the pole can be stably supported.
