Description

  The present invention relates to a joint for joining poles used for supporting a vine.

Japanese Patent Laid-Open No. 10-14409 (Patent Document 1) proposes a prior art as a joint for connecting a gardening pole. Since the pole gripping portion 1 of the technique grips the pole 8 by elastic deformation, when opening a screen or fixing a film, the opening edge of the pole gripping portion 1 is to be opened against the elasticity and inserted. In addition, since the crossing angle between the joints is in the range of 90 °, there is a problem that the direction of the joint must be changed in the crossing direction in practice.
A technique as a pipe joint for connecting pipes to each other is disclosed in Japanese Patent Laid-Open No. 6-337010 (Patent Document 2). Since the technique proposed in Patent Document 2 does not have means for connecting the connected pipe 2 and other pipes, the pipe joint 1 cannot be used as a tether used for supporting a vine or the like. There is a problem that the long groove-like window part 5 is not penetrated over both opening ends in the axial direction, so that it cannot be inserted into the window part 5 even if an edge of a net or film is caught. .
Japanese Patent Laid-Open No. 10-14409 JP-A-6-337010

  The present invention is mainly used for planters, which are used to support vines and securely connect poles facing each direction, and can connect the poles in various postures, as well as bird damage and frost damage. It tries to provide a pole joint that can be easily screened and film-stopped to protect seedlings.

The pole joint described in claim 1 of the present invention has a pair of cylindrical bodies having a required inner diameter and a required length that are joined to each other so that the joining posture can be freely changed at the joints between the circumferential surfaces. A required number of push screws are screwed from the surface toward the shaft center, and slits extending through both open ends are formed through one of the cylinders and / or the other cylinder.
According to a second aspect of the present invention, there is provided the pole joint according to the first aspect of the present invention, wherein the joint portion according to the first aspect includes a shaft rod having a retaining portion projecting from an outer peripheral surface on an orthogonal axis orthogonal to the axis of one cylindrical body And an axial hole having a retaining portion recessed in the outer peripheral surface on an orthogonal axis orthogonal to the axis of the other cylindrical body.
In the pole joint according to claim 3, the pair of cylinders are integrally joined at a required crossing angle at a joint portion between the circumferential surfaces, and each cylindrical body is directed from the circumferential surface toward the axis. A push screw is screwed together, and a slit extending through both opening ends is formed through one cylindrical body and / or the other cylindrical body.

In addition, slits that pass through both ends of the cylinder are used to insert the edges of nets, films, etc. into the inner surface of the cylinder. It can be easily sandwiched between the surface and the inner peripheral surface of the cylinder, and in planting with a planter, the seedling can be protected from bird damage and frost by a net or film.
In addition, in the case where the intersecting angles of the axial centers of both cylinders are selected as required and the both cylinders are joined together, the pole arrangement is easy to be patterned, saving labor.

The cylinder that connects the poles vertically, horizontally, vertically, or diagonally is made of PVC and the inner diameter and length are appropriately selected, but the joint between them is an orthogonal axis that is orthogonal to the axis of both cylinders. There are ones that can be rotated 360 ° above, and ones that are united at a crossing angle of 0 ° to 90 °. Further, the retaining portion of the shaft rod at the rotatable joint portion is the minimum shaft shaft diameter along with the taper shaft surface formed in an inverse taper shape and the enlarged diameter protrusion (claw) provided at the projecting end of the shaft rod. It consists of a diameter reducing means for accommodating the maximum diameter portion of the taper shaft surface and the outer diameter of the projection within the diameter, and the retaining portion in the shaft hole is a diameter expansion portion provided on the reverse taper peripheral surface or the hole bottom. is there.
Examples of the diameter reducing means include a slit (one direction or a cross direction) that is simply cut at a required width perpendicular to the axis of the shaft rod, and a clearance space provided in the axis and the slit. . Further, one or two set screws are screwed into both the cylinders from the outer periphery toward the axial center, and one cylinder and / or the other cylinder has a slit having a required width across both opening ends. Is penetrated. Therefore, as a joint, a pair of cylinders provided with slits in only one cylinder are joined at 360 ° at their joints so that their open ends can be freely changed, and one push screw is screwed to each cylinder. One, both of which have the slits penetrated in both cylinders and screwed with one push screw, and one (or both) of the cylinders with slits are elongated and two push screws are screwed. A long cylindrical body with slits and a short cylindrical body without slits are joined at the joint, and two push screws are screwed into the long cylindrical body, and one long cylindrical body is attached to the short cylindrical body. In addition to this, there are provided those in which a push screw is screwed, and those in which both cylinders are integrally joined with each other at the crossing angle of 0 ° to 90 ° in the respective patterns. In addition, an edge such as a net or film as a protective material is inserted into the slit of the cylinder, and the inserted edge is easily held between the outer peripheral surface of the pole and the inner peripheral surface of the cylinder by a push screw. Is done.

The pole joint A according to the present invention will be described with reference to an embodiment. As shown in FIG. 1, a pair of cylindrical bodies 1 and 1 having an inner diameter of 20 mm and a length of 25 mm are made of PVC.

Prevent it.
Therefore, the morning glory 6 planted in the planter 5 can be entangled with the vertical pole 4a and the horizontal pole 4b as it grows, and can blossom in a state that is easy to appreciate.

An example of providing the net 7 in the pole joint A will be described. As shown in FIG. 7, in order to protect the seedlings 8 from bird damage when the seedlings 8 such as two leaves of the morning glory 6 planted in the planter 5 are grown, With the screw 1b loosened, the edge of each of the left and right nets 7 is inserted through the slit 1c of the cylinder 1, and the edge is inserted between the outer peripheral surface of the horizontal pole 4b and the inner peripheral surface 1g of the cylinder 1. When the push screw 1b is tightened, the net 7 is sandwiched between the horizontal pole 4 and the inner peripheral surface 1g of the cylindrical body 1. A film or the like is also used for protecting the seedling 8 in the same manner as described above.
The present invention can easily prepare the support of the vine plant with a pole, and has means such as shading and film stopper that can protect the seedlings 8 from bird damage and frost damage, and does not stop for personal gardening, It is extremely useful as something that can be used in farming.

  Since the present invention is a joint that connects poles with a wide range of degrees of freedom, it is used for planter planting of vine plants, house cultivation, outdoor cultivation, and the like, and the demand is greatly expected both from an individual and farming standpoint.
