Description

[Detailed Description of the Invention] This invention relates to a cap for a shelf line support for a fruit tank in an orchard or a tension line support for a bird control net.

Traditionally, pillar caps used for the above purpose include:
Those with a cross-shaped groove in the head, those with circular holes penetrating vertically and horizontally, or those with a tension wire placed on the top end of the support pipe and the cap being hammered into the pipe and fixed to the support. something is being used.

However, the method of installing tension wire for tree branch support or fruit bird prevention nets is to attach the tension wire to the cap groove in advance, tap the cap head, and insert the insertion part at the bottom of the cap into the support. Either push it into the cylindrical part and fix it, or bury the support with the cap in the ground and push the tension wire into the cross groove in the cap head, or pass it through the cross-shaped hole and tension the wire. Was.

However, these prop caps are inconvenient and inefficient when trying to adapt them to various situations depending on the topography of the orchard or the elongation of the branches of fruit trees. .

The present invention is an improvement on these structures, and can be tensioned either when the tension wire is pre-strung or when a cap is attached to the support pipe. As shown in Fig. 5, the present invention provides a column cap that allows attachment of hanging steel wires for supporting shelf wires at the same time.

An embodiment of the present invention will be explained based on the drawings. In FIGS. 1 and 2, the hemispherical head 1 and the tube insertion part 2 are integrally molded from hard synthetic resin or semi-hard synthetic resin, and the top part From there, downward grooves 5 having a width approximately equal to or larger than the diameter of the tension wire 3 are provided so as to intersect in a cross shape, and the apex portions where the grooves at the apex intersect are covered on the cap. The corners are rounded to prevent damage to the bird netting.

Further, on both walls of the cross groove, a protrusion slightly protruding in the lateral direction is provided so that the diameter is approximately equal to or smaller than the diameter of the tension wire, forming a neck portion 4, and forcing the tension wire downward. The tension wire should be able to pass through it, and the tensioned wire should not come off easily.

The shape of the hemispherical head does not need to be a perfect circle, and may be truncated.

The pipe insertion part 2 is of a type that is inserted into the inner wall of the pipe of the strut 7, and is provided with an upward groove 6 that intersects in a cross shape with a width approximately equal to the diameter of the tensioned wire upward from the bottom bottom. The bottom of the groove reaches the bottom surface 8 of the hemispherical head.

The outer diameter of the pipe insertion part 2 is slightly larger than the inner diameter of the column, and when inserted by tapping, the elasticity of the synthetic resin is used to compress the groove and fit, preventing it from slipping out of the column. There is.

Further, it is preferable for use if the outer diameter of the tube insertion portion is the same as or slightly smaller than the hemispherical head.

FIG. 3 shows another embodiment of the present invention, in which the pipe insertion part 2 is tightly fitted to the outer wall of the pipe of the support 7, and the inner diameter of the pipe insertion part 2 is set to the outer diameter of the pipe of the support 7. It is the same as the previous embodiment except that it is made a little smaller and is hammered to firmly fit it.

Note that the groove directions of the downward groove 5 and the upward groove 6 may be made to coincide with each other, or may be provided at a twisted angle of 45° when viewed from above, as shown in FIG.

Providing the groove in the direction twisted by 45 degrees is advantageous when it becomes necessary to further tension the suspension wire in a diagonal direction with respect to the cross-shaped tension wire.

The strut cap according to the present invention has two sets of cross-shaped grooves, so if the tension wire is already tensioned, the cap may be attached to the strut by inserting the tension wire into the downward groove 5. If the wire is to be connected after supporting the struts, the tension wire may be pushed into the upward groove 6 of the cap that has been attached to the strut in advance, and the method that is easier to work with can be selected depending on the conditions of the orchard.

Further, as shown in FIG. 5, one of the two sets of cross grooves can be used for tensioning wires, and the other can be used for attaching shelf tensioning wire support and hanging steel wires, and no special hanging wire support is required.

Furthermore, a set of cross grooves with a 45 degree twist is particularly useful for diagonally extending suspension lines or supporting columns.
