DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for constructing a greenhouse or the like, and for putting or removing a greenhouse frame or the like into or out of the soil to be used for other purposes.

[0002]

2. Description of the Related Art Conventionally, when constructing a greenhouse, a greenhouse frame has to be dug and buried or pushed by human power in order to stand in the ground, and this is particularly hard work for elderly workers. Was. Accordingly, the applicant has proposed a "stepping device for a pipe frame" (Japanese Patent Application Laid-Open No. 62-119760), and engages and holds the pipe frame 50 with a vertical rod 62 of the stepping device 60 of the pipe frame as shown in FIG. After being fixed with the hand vise 66, the pipe frame 50 is pushed into the ground at a stretch while stepping on the stepping rod 64 while stepping on the stepping rod 64, so that the labor for pushing the pipe frame for the greenhouse can be reduced. It was made. .

[0003]

However, in the conventional "stepping device for a pipe frame" proposed above, since the stepping device 60 of the pipe frame is easily inclined to the side of the pressing rod 64 with one foot, the entire weight is applied at a stretch. I couldn't push it deep into the ground unless I applied my weight many times and stepped on it. In addition, it was difficult to balance when one leg was hung, so that heavy labor was required for long periods of treading work. In addition, when the pipe frame 50 is tilted, extra work labor and unnecessary work time for grasping and pulling out by hand are required, and the work efficiency is significantly reduced.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to make it possible to push a greenhouse frame into the ground very easily and to make it stand up, and to easily pull out the frame. Another object of the present invention is to provide an apparatus for effectively removing a frame of a greenhouse, which can be effectively used.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a standing and removing device for a greenhouse frame according to the present invention is provided with a frame holding member having a frame holding groove formed in a vertical direction. At an arbitrary position, there is provided a connecting and fixing member 16 for connecting the greenhouse frame in the frame holding body 14 so as not to be displaced in the longitudinal direction in a state where the greenhouse frame is engaged and held.
The frame holder 14 is located at a position relatively lower than
The operation rod 18 is provided so as to protrude from both sides with the frame holding member 14 as a center in a direction substantially orthogonal to the frame.

Further, a step 20 may be formed in the frame holder 14 in the vicinity of the position where the operating rod 18 is mounted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The upright removal device for a greenhouse frame according to the present invention is used, for example, when building or dismantling a greenhouse or the like, to put the greenhouse frame into the ground or to remove it. This is a vertical removal device for a greenhouse frame used in a car. For a greenhouse frame, for example, a long and round steel pipe such as a round shape or a square shape, or a variety of shapes such as a steel bar, an H-shaped steel, or an L-shaped steel are appropriately processed and used.

[0008] An upright removal device for a greenhouse frame (hereinafter abbreviated as an upright removal device) is provided with a vinyl holding member at an arbitrary position of a frame holding member having a frame holding groove formed in a vertical direction. There is a connecting and fixing member for connecting the house frames so as not to be displaced in the longitudinal direction with the house frames engaged and held. The shape and length of this frame holder can be freely set as long as it can be easily attached to the linear portion of the greenhouse frame, and can be engaged and held by the frame holding groove so that it does not easily fall off during upright removal work. It is. The frame holding groove may have a length and shape capable of engaging and holding the greenhouse frame in the longitudinal direction. Therefore, the frame holding member is preferably formed so as to surround the greenhouse frame. For example, a substantially U-shaped cross section is suitable. In addition, other than the U-shape, it may be formed in a shape such as a semicircle or a polygon such as a half hexagon. The point is that even if a greenhouse frame of various shapes is formed, a frame holding groove capable of securely engaging and holding the greenhouse frame may be formed, and it can be modified to an arbitrary shape according to the current situation. The material may be made of a non-metal such as a light alloy such as aluminum or a hard plastic other than the steel plate.

The connecting and fixing member connects and fixes the frame holding body and the held greenhouse frame such that the frame holding body and the held greenhouse frame do not mutually slide in the longitudinal direction due to the stepping force. Considering the efficiency of the upright removal work, it is easier to work at the upper end of the easily accessible frame holder, but the work is not limited to this and the number may be at least one or more. Any connection fixing member having a clamping force capable of integrating the greenhouse frame and the frame holding body may be used. For example, a gripping portion of a metal hand vice or the like is fixed so as not to protrude into the frame holding groove made of steel plate. It may be configured. The present invention is not limited to these configurations. For example, a configuration may be employed in which a nut member is fixed to a frame holder, and a bolt member is screwed in and pressed and fixed.

[0010] Further, a notch cut obliquely is provided on one side surface near the upper end portion of the frame holding member to insert the greenhouse frame into the frame engaging groove. The notch portion is engaged and held so as to be pushed into the frame engaging groove while being made to extend in the longitudinal direction of the greenhouse frame. In short, the cutout shape is optional as long as the greenhouse frame can be easily inserted into and taken out of the frame engagement groove and can be firmly held.

An operating rod is provided at a position relatively lower than the connecting and fixing member in such a direction as to be substantially perpendicular to the frame holder and projecting on both sides with the frame holder as a center. . As for the operating rod, for example, it is preferable that a substantially central portion of a steel pipe having an arbitrary length is fixed to the frame holder in an inverted T-shape. Therefore, the total weight applied by putting the foot on the operating rod is evenly concentrated on the center of the frame holder, that is, on the tip of the greenhouse frame that is engaged and held. In addition, if the upright removal device is turned upside down and engaged with and held by the greenhouse frame, the operating rod can be gripped with both hands and pulled upward. The shape, diameter, length, etc. of the operating rod can be arbitrarily determined as long as it can be securely pressed by the foot or gripped by hand. It may be formed. The method of fixing the operating rod is not limited as long as sufficient strength can be ensured. For example, a structure in which a steel pipe is welded or bolted or screwed is suitable.

In addition, a step is formed in the vicinity of the operation rod mounting position on the frame holder. The step is provided in the vicinity of the lower portion of the frame holder so as to form a flat portion that can be pressed with one toe. The greenhouse frame, which is engaged and held by stepping on the flat portion, is temporarily pushed vertically into the soil. By transmitting the treading force from the frame holder to the greenhouse frame as it is, it is possible to push it into the soil while maintaining its vertical position. The shape and fixing method of this step are not limited as long as the step can be reliably stepped on with the toe of the foot. For example, a configuration may be employed in which a billet, a steel pipe having an appropriate diameter, a bar, or the like is fixed by welding or fixed with bolts and nuts.
