Description

[Detailed description of the invention] This invention relates to a post with an assembly type ring that supports chrysanthemums, morning glories, and other plants.

Conventionally, this type of assembly-type ring-equipped strut has generally had a structure as shown in FIGS. 1A and 2B to 2A and 2B.

In other words, in the conventional example shown in Fig. 1A and B, a hole c into which a ring b is inserted is formed in a support post a, and a ring b is inserted into this hole c to form an assembly type support with a ring. be.

However, it is necessary to drill a hole c in the support column a, and if it is a steel pipe support, the surface must be coated with anti-rust paint or vinyl coating d, which has the drawback of increasing costs.

In addition, even steel pipes with anti-corrosion paint or vinyl coating d have the disadvantage that they cannot withstand long-term use and have a short lifespan because rainwater or sprinkled water enters through the holes c and corrodes from within.

In the conventional example shown in FIGS. 2A and 2B, a fitting part e of a support post a is provided at a proper position of a ring b, and a support post a is fitted into the fitting part e to form a prefabricated support with a ring. be.

However, when providing the fitting part e on the ring b, since a resin molded product is used with a mold, the size of the ring b is limited and the range of use is narrowed. Ring b had low strength and poor weather resistance, so it was not suitable for long-term use.

Further, there was a drawback that the ring b having the fitting part e was expensive to manufacture.

This invention was made in order to improve the drawbacks of the conventional example described above, and allows the ring to be tightly fixed in any position without drilling holes in the pillar or providing complicated fitting parts. To provide a strut with an assembly type ring, which allows the number of struts and the number of rings to be appropriately set, and is constructed so that it can be assembled easily and reliably.

Hereinafter, embodiments of this invention will be explained in detail with reference to FIGS. 3 to 6. Fig. 3 is a perspective view showing the assembled state of the assembled ring-equipped strut according to this invention. The strut 1 is made of steel pipe coated with synthetic resin, anti-corrosion painted, or aluminum, FRP, or aluminum treated with Toughlam. It is made of materials with excellent corrosion resistance, such as 2 is a partially opened coil spring wound into a cylindrical shape, and is a coil spring formed by applying rust prevention treatment such as plating to stainless steel wire or spring steel. 3 is a ring, which is made of steel wire coated with synthetic resin, steel wire treated with anti-rust treatment such as plating, or aluminum wire.

4 is a joint for the ring 3, and a steel pipe, an aluminum pipe, a cylindrically wound coil spring, or the like is used. Reference numeral 5 designates an upper end cap of the support column 1, which is made of rubber, synthetic resin, or the like. As shown in FIG. 4, the cylindrical coil spring 2 is formed of a vertical coil part 2b formed to be able to be fitted onto the support column 1, and an inclined coil part 2a connected to the coil part 2b at an appropriate angle. has been done. A suitable opening degree is 20° to 85°, and the smaller the angle, the stronger the force that presses the ring 3 and the force that brings it into close contact with the strut 1.

To assemble the strut 1 and ring 3 formed as described above, first, as shown in FIG.
Insert the number corresponding to the number of rings 3 into . At this time, a portion 2a of the cylindrical coil spring 2 is in elastic contact with the outer peripheral surface of the support column 1.

A ring 3 is attached to the part surrounded by the pillar 1 and parts 2a and 2b of the cylindrical coil spring 2 circumscribing the pillar.
are sequentially inserted and elastically supported by a portion 2a of a coil spring, and both end surfaces of this ring 3 are connected with a joint 4 to assemble.

By performing the above-mentioned operations for the number of rings 3 to be installed above and below the support 1, the support with rings is completed.
It is used by inserting it.

The above-mentioned assembly type ring-equipped strut is one in which three or four struts 1 are closely fixed to the outer peripheral surface of the ring 3 at equal intervals, but the struts 1 and ring 3 assembled in this way are When not in use, it is also possible to pull other columns to the side of one column 1, and in this way, the column 1 and the ring 3 can be folded while assembled via the cylindrical coil spring 2. can.

As described in detail above, the assembly type ring-equipped support constructed according to this invention can be assembled easily and reliably, and has the following effects.

(1) The length of the support can be changed depending on the height and size of the plant, and the fixed position of the ring can be changed freely.

(2) By changing the inner diameter, wire diameter, and opening angle of the cylindrical coil spring, it can be used even if the thickness of the strut and ring used is different.

(3) All the constituent parts are industrially produced in large quantities at low cost, so there is no need to make special molds.

(4) Materials for the struts and rings can be freely selected depending on the required durability.
