Description

  The present invention relates to a post insertion tool for mainly inserting a support for gardening into the soil or removing a support post inserted therein.

  When inserting a support for horticulture into a field, it is usually inserted only by the operator's force by holding the support directly in the hand and pushing down the support. In such a method, since a strong force cannot be applied to the column, it is difficult to insert the column deeply. If the support is driven with a spear or the like, the support itself may be damaged. Also, when removing a deeply inserted support, it may be difficult to remove it directly by hand.

Patent Document 1 discloses a concept in which a lever is provided on a side surface of a cylindrical body whose upper portion is closed, and the lever of the cylindrical body covered with a support is stepped on. Patent Document 2 discloses a concept in which a cylindrical gripping rod fitted with a lid is protruded, the cylindrical body is placed on a support, and the gripping rod is pushed down by a hand.
The insertion tool disclosed in Patent Documents 1 and 2 basically applies the force and weight of the operator to the tip of the column.

JP 2010-220599 A Utility Model Registration No. 3108636

  In the column insertion tool disclosed in Patent Documents 1 and 2, since only the operator's force and weight act on the column, a large force cannot be applied for insertion, and only on the upper end of the column. Due to the force acting, for example, the upper end of a post coated with vinyl may be damaged. In addition, the length of the column that can be inserted is limited by the length of the cylinder, and the cylinder itself is relatively long. As a result, the insertion tool itself is heavy and difficult to handle.

In view of the above-described drawbacks of the prior art, an object of the present invention is to realize a column insertion tool capable of performing not only a column insertion but also a drawing operation with a small force.
Furthermore, another object is to realize a small and more convenient structure, which can be provided at a low cost, and can be used regardless of the length of the support column, and has excellent versatility. It is intended.

The post insertion device of the present invention according to claim 1, which achieves the above object, includes the through-hole 3 and the through-hole 3 provided in the post-holding portion 1 having a through-hole 3 in the vertical direction that can penetrate the post A. It is assumed that the operation unit 2 that protrudes in the orthogonal direction, that is, the side is provided.
In order to be able to insert the column A from the side, the column holding part 1 has a substantially U-shaped section by opening the side surface, and a cross hole 4 is formed in an oblique direction intersecting the through hole 3. To do. And the support | pillar inserted into the cross-hole 4 from the open part 4a of the cross-hole 4 can be rotated relative to the support | pillar holding | maintenance part 1, and a support | pillar can be moved in the through-hole 3 of the orthogonal | vertical direction, A portion between the through hole 3 and the cross hole 4 is excised, and the through hole 3 is opened toward the cross hole 4.

According to the second aspect of the invention, the planar shape of the through-hole 3 is a diameter through which a large-diameter column can be inserted, that is, the through-hole 3 having a large radius R, and the operation portion of the inner surface 3a of the through-hole 3 (2) A concave groove having a small radius of curvature that coincides with the radius of curvature r of the outer surface of the small-diameter strut is formed at a position opposite to the extending direction. That is, a slight concave groove 7 having a radius smaller than the radius of the inner surface of the through hole 3 is formed on the inner surface 3a.
The invention described in claim 3 is to form the operation unit 2 in a horizontal bar shape and to form column holding units having different sizes at both ends of the bar-shaped operation unit.

  According to the first aspect of the present invention, an appropriate intermediate position of the column to be inserted is inserted through the opening 4a of the cross hole 4 formed in an oblique direction of the column holding unit 1, and the column holding unit is held by the operation unit. 1 is rotated to guide the column into the through hole 3. In this state, when the operation unit 2 is held and rotated in the rotated direction, a relatively large insertion force or extraction force is applied to the support column according to the principle of scissors, and the support column A is easily inserted. Or it can be extracted.

At this time, when the cross hole 4 is inserted into the support column in a direction in which the upper side is inclined inward and the lower side is inclined outward, the crossing hole 4 is rotated in a direction coinciding with the through hole. With the upper end outer side and the lower end inner side as fulcrums, a downward force acts on the column, and the column can be inserted with a relatively small force.
On the other hand, when the cross hole 4 is inserted into the support column in a direction in which the upper side is inclined outward and the lower side is inclined inward, the cross hole 4 is rotated in a direction matching the through hole, and the operation unit 2 is rotated upward. With the upper end inner side and the lower end outer side of 3 as fulcrums, an upward force acts on the support column, and the inserted support column can be pulled out with a relatively small force.
That is, the strut insertion tool of the present invention has an effect that it can be used for both insertion and extraction of the strut by using one insertion tool by turning it upside down.

As described above, the post insertion device of the present invention has an effect that the operation unit 2 can be held and the insertion and extraction of the support can be performed with a small force by the principle of the rod. Moreover, since it is the comparatively small thing comprised by the support | pillar holding | maintenance part 1 and the operation part 2 as a whole, it can provide cheaply and can utilize easily.
Furthermore, since the support | pillar holding | maintenance part 1 can be inserted and used in the arbitrary height positions of a support | pillar, it is easy to work according to an operator's physique, in other words, work can be advanced in the state where force is easy to enter. it can.
According to the second aspect of the present invention, when a column having a different size is inserted into one column holder 1 and used, the column can be used in a stable state with as little slippage as possible. Further, according to the invention described in claim 3, there is an effect that one insertion tool can be used for a plurality of types of sizes.

Hereinafter, an embodiment of a support plug according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view showing an embodiment of a post insertion device of the present invention, FIG. 2 is a front view of the post insertion device, FIG. 3 is a plan view, and FIG.

As can be understood from FIGS. 1 and 4, the column insertion tool according to the present invention is a column-shaped column holding part having a vertical through hole 3 through which a column to be inserted can be inserted. The basic structure is to provide the operating portion 2 protruding in a direction orthogonal to the through-hole 3 in 1. The operation unit 2 has a length and thickness that can be gripped. In the illustrated embodiment, two strut holders 1 and 1 having different sizes are connected by a rod-like operation unit 2.
As shown in FIG. 7, the side surface is opened at the opening 4a so that the column A can be inserted from the side so that the column A can be inserted from the side. As shown in FIG. As described above, the intersecting hole 4 is formed in an oblique direction intersecting with the through hole 3. The column inserted into the cross hole 4 from the opening 4a is rotated from FIG. 9 so that it can be moved into the vertical through hole 3 as shown in FIG. That is, the space between the through hole 3 and the cross hole 4 is cut out, and the through hole 3 is opened toward the cross hole 4 as shown in FIG. .

The above-described column insertion work using the column insertion tool of the present invention will be described with reference to FIGS. As shown in FIG. 9, for example, the support column A is inserted into the cross hole 4 of the support column holding unit 1 at a position at an arbitrary height of the support column A in a standing state.
In this state, as shown by the arrow in FIG. 9, when the operation unit 2 is rotated downward, the support column A moves into the through hole 3 as shown in FIG. 10. When the operation unit 2 is further pushed down, a rotational moment and a downward force act on the support holder 1 in the right direction in the drawing, and contact points 5 and 6 at the opening end of the through hole 3, specifically through holes The contact 5 on the inner peripheral edge at the upper end of 3 is in close contact with the surface on the left side in the drawing of the column A, and the contact 6 on the inner peripheral edge at the lower end of the through-hole 3 is in close contact with the surface on the right side in the drawing. Therefore, the force F acting on the operation unit 2 acts as a large rotational moment proportional to the distance from the fulcrum, and acts as a downward pressing force because the lower end of the column is grounded, and the column A is moved with a large force. Can be plugged in.

Next, a column extraction operation using the column insertion tool of the present invention will be described with reference to FIGS. As shown in FIG. 11, the support column A is inserted into the cross hole 4 of the support column holding unit 1 at an arbitrary height position of the inserted support column A. At this time, the support | pillar holding | maintenance part 1 makes a top and bottom reverse direction with the case shown in the said FIG.
In this state, as shown by an arrow in FIG. 12, when the operation unit 2 is rotated upward, the support column A moves into the through hole 3 as shown in FIG. When the operation unit 2 is further pushed upward, a rightward rotational moment and an upward force act on the support column holding unit 1, and contact points 5 and 6 at the opening end of the through hole 3, specifically, the through hole 3. The contact 6 on the inner peripheral edge at the upper end is in close contact with the surface of the support A on the left side in the drawing, and the contact 5 on the inner peripheral edge at the lower end of the through hole 3 is in close contact with the surface of the support post A on the right in the drawing. Therefore, the upward force F acting on the operation unit 2 acts as a large rotational moment proportional to the distance from the fulcrum, acts as a force for pulling up the inserted strut A upward, and the inserted strut is A can be pulled out with great force.

In the embodiment of the present invention, as shown in FIG. 8, the planar shape of the through-hole 3 is the through-hole 3 having a diameter D into which a large-diameter column can be inserted, and the curvature of the outer surface of the small-diameter column. A concave groove 7 having a small curvature radius r that coincides with the radius is formed. Therefore, it is possible to cope with two types of struts having different diameters in one operation unit.
A state in which a thin column is inserted using the column insertion tool according to the present invention will be described with reference to FIGS. As shown in FIG. 13, the support pillar A is inserted into the cross hole 4 of the support holder 1.
In this state, when the operation unit 2 is rotated downward, the support column A moves into the through hole 3, and when the operation unit 2 is further pressed down, the support column acts as in FIGS. Is inserted. At this time, the column A is slightly inclined in the through hole 3 and the contacts 5 and 6 at the opening end of the through hole 3 come into contact with the column A. At this time, if a small-diameter column is in contact with a curved surface having a large radius of curvature, the column A may not be stable, but a small curvature that matches the radius of curvature of the outer surface of the small-diameter column as in the illustrated embodiment. If the concave groove 7 having the radius r is formed, a thin column can be inserted or pulled out stably.

The strut insertion tool according to the present invention may be one in which one operation portion 2 is formed on one strut holder 1, but in the illustrated embodiment, there is a size at both ends of the rod-shaped operation portion 2. Different strut holders are arranged. By doing in this way, it can utilize as an insertion tool of many kinds of support | pillars from which a diameter differs.
In the insertion device of the present invention, the insertion / removal of a column slightly smaller than the diameter of the through hole 3 can be performed without any trouble by the structure of claim 2 in particular. Since it is not stable or may slide, it can be used widely as an insertion tool for a horticultural support that is normally used by forming support holders at both ends of the operation part. As described above, it is possible to correspond to two kinds of diameters of the strut in one operation portion. Therefore, when forming an operation part in the both ends of one operation part, it can respond to the support | pillar of four types of diameters. For example, it is possible to correspond to 8 mm, 11 mm, 16 mm, and 20 mm columns with one column insertion tool.
In addition, the range of the diameter of the support | pillar used generally is limited, For example, it will be rare to use it by inserting a thin support | pillar of less than 8 mm strongly.

  Moreover, although this invention support | pillar insertion tool can be manufactured with arbitrary materials, such as metal and wood, it can be provided cheaply by using a synthetic resin with some strength. Many of the horticultural supports have a surface coated with a synthetic resin material, and by using a synthetic resin support insert, it is possible to perform a stable operation that is difficult to slip and is described in the patent literature. There is no such thing as damaging the column like a plug.
