Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing water fetching bucket, and more particularly to a fishing water fetching bucket that can be in a folded state and an expanded state.

[0002]

2. Description of the Related Art Conventionally, when fishing in the sea or the like, for example, water is required for various uses such as hand washing and dough bait. For example, a rope or the like is tied to a bucket It is common practice to throw a bucket into the sea surface or the like and allow water to penetrate into the bucket, and then pull up the bucket by pulling up a rope and pumping water.

[0003] And this kind of fishing water fetching bucket,
For example, it is made of a flexible member such as an ethylene-vinyl acetate copolymer sheet or a polyvinyl chloride sheet, and when it is carried in a bag or the like, it is contracted in the vertical direction (axial direction) and folded. It can be used in a fishing place by extending (expanding) it from a folded state (folded state).

[0004]

However, the above-mentioned conventional fishing water fetching bucket is composed of a flexible member,
Because it can be folded, if you draw water and stand it up, the side opening may be bent and the upper opening may tilt due to slight impact or wind when the angler's feet or fishing rod etc. come into contact In some cases, water pumped out of the bucket sometimes flowed out.

[0005] When left in a folded state for a long time,
In some cases, a folding habit may be formed, and in such a case, it may be complicated to expand from a folded state.

In view of the above, the present invention has been made in view of the above-mentioned conventional problems, and it is possible to fold the fishing water with a low risk of the pumped water flowing out and to easily expand the fishing water. It is an object to provide a bucket for pumping.

[0007]

Means for Solving the Problems In order to solve the above problems,
A fishing water fetching bucket according to the present invention has an opening at an upper portion and is made of a flexible member. The bucket body which can be in a folded state and an expanded state is provided with an ultra-high pressure so as to maintain the bucket body in an expanded state. A strut made of an elastic material is provided.

[0008] In the fishing bucket having the above-described structure, since it is maintained in an expanded state by the struts, even if the water is drawn up and standing, the side of the bucket body is bent inadvertently and the opening is inclined. Risk is also reduced. Further, since the strut is made of a super-elastic material, the strut can be easily deformed and the bucket body can be folded (folded) as compared with, for example, a strut made of a highly elastic member such as iron. . In addition, since the folded bucket body is urged to the expanded state by the restoring force of the superelastic material against deformation, the folded bucket body can be easily expanded.

[0009] Here, the superelastic material has a superelastic function, that is, a property in which the deformation caused by the stress-induced martensitic transformation returns to the original state by the reverse transformation at the time of unloading.

As the superelastic material, a superelastic metal is preferable, and as the superelastic metal, a Ni—Ti alloy, Ni—Ti
-Co alloy, beta-alloy (Cu-Zn-Al), A
g-Cd alloy, Au-Cd alloy, Cu-Al-Ni alloy, Cu-Au-Zn alloy, Cu-Sn alloy, Cu-Z
n alloy, Cu-Zn-X (X = Si, SN, Ga) alloy, In-Ti alloy, Ni-Al alloy, Fe-Pt alloy, Fe-Pd alloy, Mu-Cu alloy, Fe-Ni-C
An o-Ti alloy or the like can be used. In particular, in consideration of repeated use, Ni-T
i-alloy and Ni-Ti-Co alloy are preferred.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a fishing water fetching bucket according to the present invention has an opening 2 at an upper edge and is formed in a bottomed column shape. In the bucket body 1, a flexible and waterproof synthetic resin sheet (for example, an ethylene-vinyl acetate copolymer sheet, a polyvinyl chloride sheet, etc.) is appropriately heat-sealed in a liquid-tight manner, and the pumped water and the like leak. Not configured.

Further, the bucket body 1 is formed by bending the sheet of the peripheral portion 5 at least in a direction intersecting with the axial direction and folding it so as to contract in the axial direction due to the flexibility of the synthetic resin sheet as a constituent member. In this configuration, it can be expanded in this state by being pulled in the axial direction.

A ring-shaped opening edge frame 7 made of steel and having substantially the same diameter as the bucket body 1 is provided at the opening edge of the bucket body 1 so that the shape of the opening 2 is not deformed. ing. Specifically, the upper end edge 8 of the sheet constituting the bucket body 1 is folded inward so as to surround the opening edge frame 7 and is partially adhered to the inner surface of the bucket body 1, whereby the bucket is formed. A ring-shaped opening edge frame 7 is held at the opening edge of the main body 1. The post 3 to be described later is inserted into a portion where the folded front edge 8 and the inner surface of the bucket body 1 are not bonded.

Further, a notch 10 is formed at the upper end edge of the peripheral portion 5 of the bucket body 1 at a position facing each other, and the opening edge frame 7 is exposed from the notch 10. . Both ends of the cord body are tied to portions 7a of the opening edge frame 7 exposed from the cutouts 10, respectively.
The cord forms a bucket handle 11. The handle 11 is usually provided with a rope 12 or the like.

A ring-shaped bottom frame having the same structure as the opening edge frame 7 is provided on the inner bottom surface 14 of the bucket body 1 along the periphery of the inner bottom surface 14 (the lower end edge of the peripheral portion 5). A body 15 is installed.

About 5 to 10 substantially straight lines are provided between the opening edge frame 7 and the bottom frame 15 so as to connect the opening edge frame 7 and the bottom frame 15. Pillar 3 is inner bottom 1
4 are provided substantially vertically (ie, substantially parallel to the axis of the bucket body 1) and at equal intervals. This support 3 has one edge on the opening edge frame 7 and the other edge on the bottom frame 1.
5 are attached by welding.

The support body 3 allows the bucket body 1 to be used.
When it is set on the ground, the sheet of the peripheral portion 5 is maintained in a stretched state without being folded, and the bucket body 1 is maintained in an expanded state.

The strut 3 is made of a super-elastic metal made of a Ni-Ti alloy and has a super-elastic function. When the bucket body 1 is contracted in the axial direction and folded (that is, when the bucket body 1 is folded) by the superelastic function, the column 3 is largely deformed, and a restoring force due to the deformation is generated. Thus, it is configured to be biased to the expanded state.

The fishing water fetching bucket according to the present embodiment is constructed as described above. When the fishing water fetching bucket is not used, for example, as shown in FIG. The upper part is rotated in the circumferential direction X (clockwise) in the fixed state, and the bucket body 1 is twisted. Then, the sheet and the support pillars 3 constituting the bucket body 1 are inclined in the upper rotating direction, and the middle part 1a of the bucket body 1 is gradually narrowed. In this state, the bucket body 1 is pressed downward from above to contract the bucket main body 1 in the axial direction against the elastic restoring force of the column 3. Then, the support | pillar 3 bends so that it may dent into the inside of the bucket main body 1, and the bucket main body 1 changes to a folded state.

As shown in FIG. 2B, when the bucket is completely folded, for example, the rope 12 or the like attached to the handle 11 is turned in the direction of arrow Y so that the bucket body 1 does not expand. Main body 1 is held in a folded state.

When using from this state, first, the rope 12 wound as described above is unwound. And pillar 3
The opening edge frame 7 and the bottom frame 15 are moved away from each other only by the restoring force of the above or by the restoring force of the column 3 and human power, and the bucket main body 1 is expanded.

The fishing water fetching bucket of this embodiment has the following advantages because it can be used as described above with the above configuration. That is, in the present embodiment, since the opening edge frame 7 and the bottom frame 15 are made of steel, that is, are made of a material having higher elasticity than the columns,
Even if the two frame members 7 and 15 are picked up and pressed so as to approach each other, there is no risk of deforming the two frame members 7 and 15, and the column 3 can be easily deformed and the bucket body 1 can be folded. .

Further, the inner bottom surface 14 is formed by the bottom frame 15.
This prevents deformation of the surface, and makes it difficult for the vehicle to roll over when it is installed on the ground by drawing water.

The fishing water fetching bucket according to the present embodiment is configured as described above and has the above-mentioned advantages, but the fishing water fetching bucket according to the present invention is not limited to the above-described configuration.
The design can be changed as appropriate. For example, in the above embodiment, the number of the columns 3 provided in the bucket body 1 is 5 to 10
Although the number is about the number of the pillars, the number of the pillars 3 is not particularly limited in the present invention, and may be any number. However, from the viewpoint of stabilizing the expanded bucket body 1, three or more are preferable.

Further, in the above embodiment, the linear support 3 is provided substantially vertically, but in the present invention, as shown in FIG. 3, the inner bottom surface 14 (the bottom frame 15) of the bucket body 1 is provided.
A case in which the coil spring-shaped support 3 extending from the upper end to the upper end portion (opening frame 7) may be provided. By adopting such a configuration, there is no need to twist the bucket body 1 in the circumferential direction,
By pressing the upper end and the lower end of the bucket body in the approaching direction, the bucket body can be folded so as to contract in the axial direction, and the fishing water fetching bucket can be easily folded. Moreover, as compared with the case of the above-described embodiment, since the deformation of the column 3 is relatively small, the column 3 is hardly damaged.

In the above embodiment, the opening edge frame 7 and the bottom frame 15 are made of a non-superelastic material (iron or steel). The case where it consists of an elastic material may be sufficient. By adopting such a configuration, the bucket main body 1 can be folded in any direction, is less bulky, and can be easily stored in a bag or the like.

[0027]

As described above, the fishing water fetching bucket according to the present invention can be easily folded, but also has a reduced risk of tilting of the opening, so that there is a risk that the pumped water flows out. Less and due to the restoring force of the superelastic material,
It has the advantage that it can be easily expanded.
