Description

[Detailed Description of the Invention] The present invention relates to a connecting device for cross-fixing horticultural supports, particularly synthetic resin-coated steel pipe supports.

Gardening supports are indispensable for growing crops in farms and home gardening, and recently supports made of steel pipes coated with synthetic resin have become widely used. These supports are planted along the trunk of the plant and used to directly hold the trunk, or are used by cross-connecting vertical and horizontal supports to form a fence. When assembling into a fence like the latter, it is common to tie the intersections with wire or use appropriate fasteners to secure the two, but this is cumbersome and the fasteners are large. There were problems such as the hanger making it unsuitable for household use.

The present invention has been developed in view of the above, and it is an object of the present invention to provide a new and convenient cross-connection tool for gardening supports that is simple yet allows stable cross-connection to be achieved with a single touch.

An embodiment of the present invention will be explained based on the accompanying drawings. Fig. 1 is a perspective view and a partially enlarged perspective view of a horticultural support structure assembled using a typical connector of the present invention, and Fig. 2 is a partially enlarged perspective view. A perspective view of the connector used in Figure 1,
FIG. 3 is a perspective view of another embodiment. That is, the present invention is a connecting tool 3 bent into a clip shape for fixing vertical and horizontal supports 1 and 2 to each other at their intersections 12.
The body of one of the pillars 1 is elastically clamped in the centripetal direction,
In addition, a pair of clips 31, 31 are bent to elastically bias the support 1 toward the bent base side, and each of the clips 31, 31 is divided into two, and a bent portion 3 of the clip is formed.
There is a slit-like notch 321 having a notch toe at a position close to 0, and the slit-like notch 321 including the opposing toe is connected to the other support 2 that intersects with the above-mentioned support 1. A holding part 32 is formed to externally hold the body part of the supporting member 1, and thereby, the elasticity of the above-mentioned one pillar 1 which is elastically clamped towards the bending base part 30 side,
This is a cross-connecting tool for horticultural supports, characterized in that by holding the other support 2 by the holding portion 32, both the supports 1 and 2 are in a tight state and are integrally cross-fixed to each other. .

The connector 3 shown in FIG. 1 and FIG.
The curved portions 311 and 3 are bent in the shape of a tongue so that the curved portions 311 and 31 are bulged outward.
11 elastically clamps the support 1 (the vertical support is shown in the figure), and a slit 321 is cut out from the tips of the clamping pieces 31, 31 so as to cross the curved parts 311, 311 toward the base 30, The deepest part of this cut slit 321 is the support 2
(The figure shows the horizontal support) Holding part 3 that fits and holds the
2, and furthermore, a guide piece 31 is provided at the tips of the clamping pieces 31, 31 with legs spread outward to facilitate press-fitting of the support column 1.
2,312 are formed.

To connect the vertical and horizontal struts 1 and 2 using this connector 3, first press-fit the circumferential body of the horizontal strut 2 into the slit 321 from the tips of the clamping pieces 31, 31, and then insert bring about. Next, the horizontal support 2
The circumferential body of the vertical support 1 that is orthogonal to the guide piece 31
2 and 312, and forcefully push it in so that it is clamped by the curved portions 311 and 311, and the connection is completed. The vertical support 1 is stably held by the inward elastic pressing force of the opposing pincers 31, 31, and
The horizontal support 2 is fitted and held by the holding part 32, and the vertical support 1 is prevented from coming off into the opening of the slit-like notch 321, and the clamping piece 3 of the vertical support 1 is
1 and 31, the struts 1 and 2 are cross-fixed and integrated with each other in a tensioned state. In particular, when the struts 1 and 2 are made of synthetic resin-coated steel pipes as described above, the elasticity unique to the synthetic resin is combined with the clamping force and fitting force of the curved portions 311, 311 and the holding portion 32, making the fixation of both more stable. It is considered to be In addition, metal, hard synthetic resin, etc. can be freely used as the connector, but if metal is used, the cutout during processing is rigid and sharp, so it is difficult to use a support that is clamped or press-fitted. This cut cuts into the circumferential bodies of the supports 1 and 2, preventing the supports 1 and 2 from shifting in the longitudinal direction, thereby achieving an even more stable connection relationship.
Furthermore, since the connection procedure is extremely simple as described above, and the overall shape is extremely simple, the appearance of the horticultural support structure assembled using this connector 3 (see Fig. 1) is degraded. Therefore, it is not only suitable as a connecting tool for home gardening supports, but also extremely convenient for agricultural use in growing large quantities of crops.

The connector 3' in FIG. 3 shows another embodiment,
This embodiment is substantially the same as the first embodiment, except that the holding portion 32' is formed in a hook shape closer to the tip of the clips 31', 31' than the base of the clips 31', 31'. Even in this case, the horizontal strut externally held by the holding part 32' is held by the clamping piece 3.
The vertical struts sandwiched between 1' and 31' prevent the vertical struts from coming off, and the elastic biasing of the vertical struts toward the bent base side allows both struts to be brought into tension and cross-fixed together.
The other functions are also the same as those of the first embodiment, and both pillars are stably connected and fixed.

It should be noted that the shapes of the connectors 3, 3' are merely examples, and it goes without saying that other shapes are not excluded. In particular, the connectors 3, 3' hold the vertical support 1 with the clamping pieces 31, 31, 31', 31', and the horizontal support 2 with the holding parts 32, 32'.
Although the support relationship is designed to be held externally, it is also possible to reverse the support relationship vertically and horizontally, and therefore, it is natural that the respective shapes (sizes, etc.) may differ from the illustrated example.

As mentioned above, the connecting tool of the present invention is simple yet capable of stably connecting and fixing vertical and horizontal supports, and is a highly commercially valuable connecting tool that is widely used for gardening, whether for home use or agriculture. be.
