It becomes.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wire extender for bonsai, which is wound around a trunk or a branch of a bonsai and then extends a spirally bent wire that is later removed from the bonsai.

[0002]

[Prior art]

 When bonsai is cultivated, pruning is performed to adjust the tree shape, but at the same time, so-called wire hanging is performed. Wire hanging involves wrapping a wire of appropriate thickness around the trunk or branches of a bonsai tree and bending the wire into the desired shape to shape the trunk or branches. However, it may eat into trunks and branches and lose their vigor or die.

When the desired tree shape is obtained, or when the wire gets into the trunk, the wire is removed and wrapped again. It bends according to the thickness of the branches, etc., and has a spiral shape, which cannot be reused as it is. Strike it with a mallet for the purpose of reusing a spiral or bent wire, but it did not become a true straight line. For this reason, when the wire was wound around a branch or the like for reuse, the winding pitch was irregular and the appearance was poor.

[0004]

[Problems to be solved by the device]

 In view of the above points, the present invention has an object to obtain a wire extender for bonsai that allows a spiral short wire unwound from a bonsai to be linearly extended and reused.

[0005]

[Means for Solving the Problems]

 An extension arm having wire end locking means is pivotally supported on a base member provided with a wire arm end fixing means so that it can be fixed at an appropriate position by the fixing means. .

[0006]

[Action]

 One end of the spiral and indefinitely bent wire removed from the bonsai tree is fixed by the wire end fixing means provided on the trunk arm, and the other end is extended by the wire end locking device provided on the extension arm. Secure it to your arm. Then, fix the base member that axially supports the extension arm at a position where the angle between the extension arm and the wire is close to a right angle, hold down the tip of the trunk arm, and pull the extension arm in the direction of extending the wire. This extends the spiral or other bend of the wire to make it straight.

【Example】

 An example of the implementation of the wire extender 1 for bonsai of the present invention will be described below with reference to the drawings.

A wire end fixing means 3 is provided at one end of a round bar or square bar-shaped trunk arm 2. The wire end fixing means 3 is such that the washers 5 and 6 are fitted to the screw rod 4 provided at the end of the trunk arm 2 and they are tightened with the butterfly screw 7. The wire ends are extended between the washers 5 and 6. The end of the wire 8 is hooked on the screw rod 4, and the washer 5 is tightened by the butterfly screw 7, and one end of the wire 8 is fixed to the screw rod 4. A handle 9 is attached to the tip of the screw rod 4.

A base member 10 is slidably fitted to the trunk arm 2. The base member 10 is provided with a base fixing member 11 for fixing the base member 10 to the trunk arm 2. The base fixing member 11 is formed by screwing a screw shaft 13 having a knob 12 onto the base member 10, and a head 14 of the screw shaft 13 is fitted into a long groove 15 provided in the trunk arm 2 and the screw shaft 13 is screwed. When screwed in, the head 14 hits the innermost wall of the long groove 15 and the trunk arm 2 and the base member 10 are fixed.

An extension arm 16 is rotatably supported on the screw shaft 13 so as to be capable of turning. The elongated arm 16 is provided with a plurality of small holes as the wire end locking means 17 at appropriate intervals. A handle 18 is provided at the tip of the extension arm 16.

A support base 19 is provided on the base member 10. The support base 19 has a spherical member 20 on the top thereof fitted into a receiving member 21 fixed to the base member 10 so that the trunk arm 2 can be set at an appropriate angle with respect to the support base 19. When the bonsai wire extender 1 is small, the support base 18 does not necessarily have to be provided.

In order to extend the wire 8 in the device of the present invention, one end of the wire 8 is fixed by the wire fixing means 3. That is, one end of the wire 8 is fixed to the tip of the trunk arm 2 by loosening the wing screw 7 and tightening the wing screw 7 by engaging one end of the wire 8 with the screw rod 4 between the washers 5 and 6. The other end of the wire 8 is fixed to the extension arm 16 by inserting it into a small hole which is the wire end locking means 17 of the extension arm 16 and folding it back appropriately.

At this time, the position of the base member 10 is adjusted so that the angle formed by the wire 8 and the extension arm 16 is 90 °. To adjust the position, the knob 12 of the screw shaft 13 of the base fixing member 11 is turned to release the contact between the head 14 of the screw shaft 13 and the inner wall of the long groove 15 to release the base member 10 and the trunk arm 2. The base member 10 is moved to a position where the wire 8 and the extension arm 16 are orthogonal to each other as described above, and the knob 12 is rotated to fix the base member 10 to the trunk arm 2. Then, holding the handle 9 of the trunk arm 2 and the handle 9 of the extension arm 16, the support base 19 is placed on an appropriate support object and the extension arm 16 is turned in the direction in which the wire 8 is extended. As a result, the wire 8 is extended and the spiral shape and other bends are corrected into a linear shape.

The movement of the base member 10 is for attempting to extend the wire 8 with the least force and for responding to changes in the length of the wire 8.

[0015]

[Effect of device]

 The wire extender for bonsai according to the present invention is an extension arm having a wire end locking means on a base member provided on a trunk arm having wire end fixing means so that it can be fixed at an appropriate position by the fixing means. Since it is rotatably supported by a shaft, a wire which is wound around a trunk or a branch of a bonsai tree or other variously bent wires is used as a wire end fixing means and a wire end locking means. The wire can be easily extended by simply fixing it to the arm and turning the extension arm or the main arm to obtain a linear wire.

Moreover, since the fulcrum of the extension arm can be moved by moving the base member, the optimum fulcrum position can always be selected according to the length of the wire, and the extension processing can be performed with the minimum force. Become.
