Description

[Detailed Description of the Invention] The present invention mainly relates to the improvement of a branch support device used for fruit tree cultivation.

In conventional fruit tree cultivation, a forked resin branch support is inserted and fixed so as to cover the top of the support.
This supports the branches of fruit trees from below.

Therefore, it is necessary to prepare various types of supports with different lengths depending on the height of the branch, and to select and use them. The attachment must be replaced every time the condition changes, which is inconvenient and uneconomical for users to handle.

In order to solve these problems, the present invention is devised so that the height of the branch supports can be adjusted and fixed extremely easily and reliably, while using the same pillars of a fixed length.

Hereinafter, the specific configuration of the present invention will be explained based on the illustrated embodiment. First, in FIGS. Hollow steel pipe with circular cross section 2 for durability and rust prevention.
and the synthetic resin cladding tube 3 integrally adhered thereto.

Reference numeral 4 indicates a joint of the support tube 1, which integrally projects from the cladding tube 3 in a concentric ring shape, and is arranged in multiple stages at regular intervals on the support tube 1, so that the cladding tube 3
For example, if the color is set to green using colored synthetic resin, the support pipe 1
It has a natural bamboo-like appearance and blends into the landscape of the orchard.

The lower end of such a support pipe 1 is used by being grounded to the ground surface or slightly inserted into the ground. Although not shown, a synthetic resin umbrella-shaped stopper is attached to the support pipe to prevent it from sinking too far into the ground. It is preferable to fit it onto the lower end of 1.

The branch support 5 is a cylinder integrally formed from synthetic resin, and is connected to the support pipe 1 so that it can be raised and lowered freely, and the support arm 6 that extends sideways from the middle of the support arm 6 is used to support the under branches of fruit trees, etc. Insert the receiver and support it from below.

Reference numeral 7 indicates a male thread carved in the middle of the body of the cylinder 5 at a position below the support arm 6, and 8 is a thin tapered surface formed on the outer peripheral surface of the lower end of the cylinder 5. A plurality of grooves 9 are cut into the tapered surface 8 and extend in the vertical direction at regular intervals, so that contraction and deformation of the diameter can be performed.

In addition, 10 is a synthetic resin operation ring for height adjustment, and the outer circumferential surface of its body is lined with anti-slip protrusions 11 during rotation operation, while the inner circumferential surface is A female thread 12 is formed to be screwed into the male thread 7 of the cylinder 5, and a pressing tapered surface 13 corresponding to the tapered surface 8 of the cylinder 5 is formed.

This pressing tapered surface 13 gradually presses the tapered surface 8 of the cylinder 5 in the radial direction when the operating ring 10 screwed onto the cylinder 5 is rotated in the tightening direction. , the skill is to forcibly contract and deform the diameter D (inner diameter) of the tube 5 together with the groove 9, and bite and fix it to the support pipe 1, so the taper inclination angle is determined by the skill. Of course, the angle is set to be slightly steeper than that of the tapered surface 8 of the cylinder 5.

In this case, in the basic example shown in Figures 1 to 3, the diameter of the tube 5 is predetermined to be slightly larger than the outer diameter d of the joint 4 in the support pipe 1, so that The technique is such that the tube 5 can be moved up and down smoothly at all times along the support pipe 1, and when the operation ring 10 is tightened and rotated, the lower end edge of the tube 5 is contracted and deformed at the joint 4. The structure is such that it is restrained from below and fixed so that it cannot fall due to its impact support action and the above-mentioned bite action.

Next, FIGS. 4 to 7 show modified examples of the present invention, but in this case, the technique is loose so that the tube 5 does not always cross over the joint 4 of the support pipe 2, but is similar to the basic example described above. The configuration differs from that of

That is, the required number (
In the illustrated example, four concave notches 14 are cut out, and protrusions 15 corresponding to the concave notches 14 are protruded from the inner circumferential surface of the cylinder 5. Only when the tube 5 is rotated so that the notches 14 match, the tube 5 can move up and down while passing through the joint 4 of the support pipe 1.

Therefore, the skill is that the length of the tube 5 is the 4th point in this modification.
is set to be shorter than the interval.

Even in this configuration, the operation ring 10 is tightened during rotation, and the ability to prevent the tube 5 from falling is due to the impact support effect from below due to the protrusion of the joint 4, and the crimping effect with the bite to the support pipe 1.
After all, a synergistic effect will definitely be achieved.

The rest of the configuration is substantially the same as that of the basic example, so the same reference numerals as those in FIGS. 1 to 3 are used in FIGS. 4 to 7, and detailed explanation thereof will be omitted.

As described above, the technology of the present invention is that the device has the support pipe 1 with the protruding joint 4, the pipe 5 that is connected to the support pipe 1 so as to pass through the joint 4 and move up and down, and the technology of the device. The skill of contracting and deforming the diameter of the tube 5 and fixing it to the support pipe 1 so that it cannot fall is different from the operation ring 10 for height adjustment.
There is no need to prepare and use different types of supports with different lengths as mentioned at the beginning, and even though the same fixed-length support pipe 1 is used, the workmanship can be improved by moving the tube 5 up and down along the support pipe 1. The height can be adjusted.

In addition, the adjustment state is such that the cylinder 5 is forcibly contracted and deformed by the force of the cylinder 5 against the support pipe 1, so that the cylinder 5 is fitted into the support pipe 1. This, together with the fact that the joint 4 is protruding from the support tube 1, makes it extremely stable and strong.Moreover, since the operation requires simply rotating the operation ring 10, the skill required to adjust the height is very high. The work can be done extremely easily and smoothly, and it can be said to be the most convenient device for practical use as a material or tool that is used in large quantities in fruit tree cultivation.
