Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a stretchable handle structure, and more particularly to a stretchable handle structure in which a ball net or plant scissors is fixed to the tip and the entire length thereof is easily changed.
[0002]
[Prior art]
Generally, a ball net used for scooping the fish caught by a hook provided at the tip of a fishing line from the water in fishing or temporarily staying in the water to delay the weakness of the captured fish has a long shape. The handle can be freely moved by grasping the handle with fingers.
[0003]
In this case, the configuration of the handle to which the ball net is fixed is inconvenient to carry if it is fixedly configured using one long bar-shaped member, so that a plurality of bar-shaped members can be connected in the longitudinal direction. The plurality of rod-shaped members are bundled and transported when being carried, and the plurality of rod-shaped members are connected in the longitudinal direction to be used as one rod-shaped member when actually used.
[0004]
Therefore, when the optimal pattern length is determined when actually used, for example, when performing at a fishing pond, there is no particular problem, but in the case of surf fishing, etc., the terrain is not determined and the pattern length is unified. If the pattern cannot be determined, a configuration is adopted in which the length of the handle becomes flexible.
[0005]
An example of a stretchable handle structure to which such a ball net is attached will be described with reference to FIG. 9 showing an expansion time and FIG. 10 showing a contraction time. A plurality of telescopic tubes (first telescopic tube 12, second telescopic tube 13, and third telescopic tube 14) made of a tubular member are fitted coaxially in a state where dropping is regulated, so that the entire length in the longitudinal direction can be freely expanded and contracted. The grip portion 11 is fixed to the lowest telescopic tube (first telescopic tube 12) of the first telescopic tube 12 to the third telescopic tube 14 forming this telescopic portion. And a net frame 15 as an attachment member is attached to the uppermost telescopic tube (third telescopic tube 14) of the first telescopic tube 12 to the third telescopic tube 14 forming the telescopic portion. 15 is provided with a net 16.
[0006]
Therefore, the handle length can be set to a desired value by expanding and contracting the relative position between the grip portion 11 and the third telescopic tube 14.
[0007]
In addition, the mode of the attachment member provided on the uppermost telescopic tube (the third telescopic tube 14) of such a telescopic part is not limited to the case of the net frame 15, and is used for cutting the branch of a plant tree located at a high place. In some cases, plant shears are attached.
[0008]
[Problems to be solved by the invention]
The conventional telescopic handle structure allows the handle length to expand and contract to a desired value, but when the mounting member is a ball net, when scooping the fish caught by the hook of the fishing line, Regardless of the fish separation distance, extend the telescopic part once and at the same time, hold the fishing rod between the rocks and hold it between the rocks, hold it with both feet, and in this state use both hands to contract the elastic part of the ball net Then, the captured fish will be taken up.
[0009]
Therefore, when the fishing rod is sandwiched and held between the rocks, there is a risk that the expensive fishing rod may be damaged or broken by the rock, and when the fishing rod is sandwiched and held between both feet, it is unnatural. There is a problem that a fisherman standing on a rocky area is in danger, because it forces the capture of captured fish in a body shape.
[0010]
In the case where the attachment members are plant scissors other than the ball net, the extension and contraction of the handle length by the extension and contraction portion must be performed entirely by hand.
[0011]
Therefore, an object of the present invention is to provide a stretchable handle structure that can perform a stretching operation in a stretching portion provided with a ball net, a flower scissors, and the like with a simple operation.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. First, a first embodiment will be described with reference to FIGS. This embodiment is an example in which the extendable handle structure of the present invention is applied to an extendable portion provided with a fishing net.
[0022]
The extendable handle structure of the present embodiment has a configuration as shown in FIG. 1 at the time of extension and FIG. 2 at the time of contraction. That is, the plurality of telescopic tubes (first telescopic tube 4, second telescopic tube 5, and third telescopic tube 6) formed of a tubular member are fitted coaxially in a state where dropping is regulated, thereby reducing the overall length in the longitudinal direction. The expansion and contraction section is configured to be able to change the expansion and contraction. The grip portion 3 is fixedly provided on the lowest telescopic tube (first telescopic tube 4) of the first telescopic tube 4 to the third telescopic tube 6 forming the telescopic portion, and the third telescopic tube forming the telescopic portion is also provided. The net frame 1 as an attachment member is attached to the uppermost telescopic tube (third telescopic tube 6) among the first telescopic tube 4 to the third telescopic tube 6. The screen frame 1 is provided with a screen 2.
[0023]
Further, one end is fixed to the lowermost portion inside the uppermost third telescopic tube 6 using the fixing member 3d, and the other end is provided below the lowermost first telescopic tube 4. A flexible wire 3c wound around a winding member 3b (winding reel) provided on the third member 3 is provided.
[0024]
The winding center rotation shaft of the winding member 3b is connected to a motor 3a built in the grip portion 3 via a speed reduction mechanism (not shown), and the winding member 3b is rotated by rotating the motor 3a to connect the wire to the winding member 3b. It is configured such that a rotational power source capable of rotating in the winding direction is provided.
[0025]
The motor 3a is provided with a holding member (not shown) that can stop the rotation of the winding member 3b in a state where the first telescopic tube 4 to the third telescopic tube 6 are expanded, and the winding member 3b by the holding member is provided. And a release member (not shown) for releasing the rotation stop state of the camera.
[0026]
Therefore, when the first telescopic tube 4 to the third telescopic tube 6 are in the expanded state during use, the wire 3c wound around the winding member 3b is brought out.
[0027]
When the motor 3a is rotated, the winding member 3b is rotated, the wire 3c is wound, and the gripping portion 3 is connected to the contracted state of the stretchable handle structure in the expanded state. The separation length between the net frames 1, that is, the handle length can be shortened, and this operation can be performed only by pressing a motor rotation switch (not shown), so that the conventional two-hand operation is not required. Therefore, convenience can be improved.
[0028]
In the present embodiment, the power for rotating the wire 3c in the winding direction is performed by the rotating force of the motor. However, the long spring member is wound to retain the energy, and the energy is stored. By releasing the holding of the power, the wire 3c may be rotated in the winding direction. Further, although the first telescopic tube 4 is configured to be able to expand and contract with respect to the grip portion 3, it may be configured so that the grip portion 3 and the first telescopic tube 4 are fixed.
[0029]
Next, a second embodiment of the present invention will be described with reference to FIGS. The present embodiment is an example in which the extendable handle structure of the present invention is applied to an extendable portion provided with a ball net for fishing.
[0030]
The telescopic handle structure to which the ball net (not shown) is attached is composed of a plurality of telescopic tubes (first telescopic tube 8, second telescopic tube 9, third telescopic tube) as shown in FIGS. The telescopic portion is configured so that the entire length in the longitudinal direction can be telescopically changed by fitting coaxially in a state where the pipe 10) is controlled to fall off, and the first telescopic tube 8 to the first telescopic tube 8 that form this telescopic portion. A first telescopic tube 8 to a third telescopic tube 10 having a grip portion 7 fixedly provided on the lowest telescopic tube (first telescopic tube 8) of the three telescopic tubes 10 and forming a telescopic portion. A ball net as an attachment member is provided on the uppermost telescopic tube (third telescopic tube 10).
[0031]
Inside the uppermost telescopic tube (third telescopic tube 10) located at one end of the telescopic part composed of the first telescopic tube 8 to the third telescopic tube 10, a cross section made of a highly rigid material is used. One end (start end) of the U-shaped or arc-shaped thin plate-shaped member (wire) 7c is fixed using a fixing member 7f (see FIG. 5). The thin wire 7c preferably has self-extensibility. The intermediate portion of the thin wire 7c is supported by a support member 7e provided at the lower end of the second telescopic tube 9 (see FIG. 6), and then a support member 7d provided at the lower end of the first telescopic tube 8 The other end side of the thin wire 7c is wound around a winding member 7b as shown in an enlarged view in FIGS. 7 and 8, and its end is fixed to the center of the winding member 7b. I have. The winding member 7b is connected to the motor 7a via a speed reduction mechanism (not shown).
[0032]
Therefore, when the motor 7a is rotated in one direction and the winding member 7b is rotated in the direction in which the thin wire 7c is wound, the distance between the grip portion 7 and the third telescopic tube 10 is reduced, and the length of the telescopic portion is reduced. On the other hand, when the motor 7a is rotated in the other direction and rotated in the direction in which the thin wire 7c is fed out, the distance between the grip portion 7 and the third telescopic tube 10 is widened, and the total length of the telescopic portion is increased. It is.
[0033]
The rotation shaft of the winding member 7b is supplied with power via a reduction mechanism (not shown) for the rotation of the output shaft of the motor 7a. A reverse drive prevention mechanism (for example, a worm wheel gear mechanism) for preventing the overall length from changing when a pushing force or a pulling force is applied is interposed.
[0034]
Therefore, by controlling the rotation by the motor 7a so as to rotate forward / reversely / stop, the distance between the grip 7 and the third telescopic tube 10, that is, the length of the handle can be increased or decreased. By controlling the stop of the motor 7a at the position (1), the pattern length can be set to a desired position. Further, the thin wire 7c has a U-shaped or U-shaped cross section and has self-extensibility, so that it not only possesses the function of regulating the position in the torsional direction but also has a resistance to the force in the bending direction. As a result, not only the torsion does not occur in the ball net, but also the telescopic tube can be linearly expanded and contracted.
[0035]
In the above two embodiments, the stretchable handle structure of the present invention is applied to the handle of the ball net, but it is configured with the plant shears for cutting a part of the plant, and the plant shears are used. The present invention can be similarly applied to a case where an operation member for remote operation is added near the grip portion, and it is required to expand and contract the handle length as well as in the case of ball nets and flowering scissors. It is a matter of course that the extendable handle structure of the present invention can be applied to all the operation members at a high place or a remote position.
[0036]
【The invention's effect】
As is apparent from the above description, the extendable handle structure according to the present invention can perform contraction and expansion and contraction of the handle length by a simple operation using the stored power of the motor or the leaf spring as the rotational power source. Therefore, in the case of a ball net, there is no risk of the expensive fishing rod being damaged or broken by the rocks, and there is no need to hold the fishing rod between both feet, so catching fish with an unnatural body shape The fisherman standing on the rock can operate safely without forcing. When the attachment member is a plant scissors other than the ball net, the extension and contraction of the handle length by the extension and contraction portion can be performed by a simple operation.
[0037]
Therefore, according to the present invention, it is possible to provide a stretchable handle structure that can perform a stretching operation in a stretching portion provided with any of a ball net, a plant scissors, and the like by a simple operation.
