Description

  The present invention relates to a bucket for fetching water, in which a bucket body is dropped into water from a high place, and the attached drawstring is drawn to draw water.

Water buckets are used to draw water from the sea, rivers, etc. when water is needed, such as washing hands, playing with water, preparing food for fishing, and washing items.
In use, the bucket body is dropped into water, and after the bucket body is filled with water, an operation of pulling the drawstring attached to the bucket body is performed.
However, the opening of the bucket body may come into contact with or be caught by underwater obstacles, rocks, etc. In addition to the inconvenience, the bucket body is also damaged and worn out.
Also, there are water flows and waves in the water, and when the opening is fully open, it may be pulled with a very strong force, and there is a risk of damaging the hand holding the drawstring or falling out of balance .

  In order to eliminate such drawbacks, for example, having a structure in which the opening of the container closes when the container is pulled up, for example, in the vicinity of the opening side periphery of the side wall of the substantially columnar container main body opened upward, Four perforations are provided in order along the entire circumference of the side wall, a first string is inserted into two of the perforations, and a second string is inserted into the remaining two perforations. One end of one string and one end of the second string are connected to form a connecting portion 5, and the other end of the first string and the other end of the second string have two outer diameters larger than the inner diameter of the perforation. Each of the stoppers is provided, and when the connecting part is pulled in a state where water enters the container body, the side wall of the container body is deformed and the opening of the container body is substantially linear. Fishing containers that can be closed are known (for example, see Patent Document 1). .

  Further, although it is not provided with a configuration in which the opening of the container is closed, in a fishing bucket formed of a sheet of synthetic resin, the opening of the container is made more than the sheet forming the container. The cover body has a thick thickness and is covered with a cover body formed in a curved shape from the inside to the outside of the opening, and the container body has a frame along the opening, and the cover body formed in the curved shape. Is known for fishing buckets having an inner diameter larger than the outer diameter of the frame and covering the frame (see, for example, Patent Document 2).

  Further, as an invention previously made by the present applicant, a bucket body formed of a synthetic resin sheet and having an opening at an upper end thereof, a fastening string attached in the vicinity of the opening, and a reinforcing means for reinforcing the opening In the water pumping bucket, the reinforcing means has a flexible part at least partially, and the flexible part is deformed when the water is pumped, and the opening part is in a reduced diameter state. A water pumping bucket is known (for example, see Patent Document 3). In the invention according to Patent Document 3, the reduced diameter state of the opening is a state in which the outer diameter is small if the opening is circular or elliptical, and if the opening is polygonal, A state in which the diameter dimension of a circular or elliptical virtual contour line passing through each vertex of the polygon is reduced.

In the invention according to Patent Document 1, the opening of the container body is substantially linearly closed.
For this reason, it can be solved to some extent that the opening of the bucket body comes into contact with or catches an obstacle in the water or a rocky place. Moreover, although not disclosed in the Patent Document 1, when the opening is closed, when performing an operation of pulling the drawstring, the resistance of water is reduced, and the effect of facilitating the water drawing work can be obtained. .

However, since both ends of the closed opening project to the side, the projecting part may come into contact with or catch underwater obstacles, rocks, etc., and the above disadvantage cannot be solved completely. It was a thing. In addition, the projecting portion of the opening is liable to be in contact with obstacles in water, rocky areas, and the like, and has a drawback that it is quickly damaged.
Furthermore, according to the structure of the said patent document 1, when the opening part obstruct | occludes linearly, the whole bucket main body deform | transforms. For this reason, the water once pumped into the container overflows in a large amount until the opening is closed, and there is a drawback that it is difficult to pump out a sufficient amount of water with respect to the size of the bucket body.

  On the other hand, in the invention according to Patent Document 2, since the opening is covered with a cover body having a thickness larger than that of the synthetic resin sheet forming the container body, the cover body is cliff or breakwater when water is pumped up. Even if it is pulled up along the wall surface, it is difficult to break.

  However, in the invention according to Patent Document 2, since the shape of the opening does not change, when performing an operation of pulling the drawstring, the resistance of water increases, and the work of drawing water is laborious.

  Next, the invention according to Patent Document 3 has an effect of reducing the resistance of water and facilitating water drawing work by reducing the size of the opening, and also projecting the opening to the side. By reducing the amount, it is excellent in that the contact with obstacles and rocks in water can be remarkably reduced, and the problems of Patent Documents 1 and 2 can be greatly reduced. It was.

However, when the water-pumping bucket is placed after pumping up the water, the state in which the diameter of the opening is reduced is firmly maintained, and it is necessary to perform an operation of opening the opening greatly when used thereafter.
For this reason, for example, if the opening operation is performed in a state where the hand is dirty, the opening portion, the outer surface, the tightening strap, etc. of the water fetching bucket are soiled, and other things such as fish and fishing rods that are picked up are held with one hand Therefore, if the diameter of the water-drawing bucket is maintained, it is necessary to perform an operation of opening the opening with one hand, which may be inconvenient for the operator.

  In addition, when the opening is contracted or expanded, the portion of the fabric in the vicinity of the opening that is deformed becomes a fixed portion. Therefore, the portion is easily damaged by the repeated contraction and expansion. For this reason, compared to the conventional case, it is possible to use it for a longer period of time by avoiding contact with a rocky place by reducing the diameter of the opening and avoiding accidental accidents, but structurally for a longer period of time. It is desirable to be able to ensure durability.

  The present invention has been made in view of the above circumstances, can stably pump a sufficient amount of water, improves the convenience after pumping by eliminating the need to open the opening, and for a long time. It is an object of the present invention to provide an excellent water pumping bucket that can improve the durability of the opening or its vicinity over the entire area.

A bucket body formed of a synthetic resin sheet and having an opening at the upper end, a fastening string and a hole through which the fastening string is passed in the vicinity of the opening, a weight in the opening or in the vicinity thereof, and the opening when pumping water In the water-drawing bucket in which the portion is in a reduced diameter state, the opening rim is provided with a restoring edge portion having a resilience elastic material, and a portion of the tightening string that is disposed inside the opening portion is penetrated by the tightening string. Each of the tightening cords that are provided on the outside of the bucket body other than the suspended portion of the tightening cords, the outer diameter of the restriction regulating member is larger than the inner diameter of the hole through which the tightening cords pass. A water fetching bucket characterized by having a fixing part is used as a means for solving the problem.
In the present invention, the water pump bucket whose opening is reduced in diameter is a state in which the outer diameter is small if the opening is circular or elliptical, and the opening is polygonal. In addition, it means a water fetching bucket in which the diameter dimension of a circular or elliptical virtual contour line passing through each vertex of the polygon becomes small.

  Further, according to the present invention, on the premise of the configuration of the above invention, the fixing portion is disposed at both the left and right positions of the tightening string exposed to the outside of the bucket body, and the distance between the fixing members is determined by the fixing portion. A water pumping bucket characterized by being less than a distance between adjacent or abutting hole portions at both ends of the string and not causing slackening of the tightening string in a state where water is pumped. Means.

  Further, in the present invention, on the premise of the configuration of any of the above inventions, the rebound elastic material is provided along the inner edge of the opening of the bucket body, and the edge of the rebound elastic material and the opening of the bucket body are provided by the edge frame sheet member. A water fetching bucket characterized by having a covered structure is used as a means for solving the problem.

  Further, according to the present invention, on the premise of the configuration of any one of the above-described inventions, the hole portion is formed of a pigeon, and the inner diameter of the pigeon that is in proximity to or in contact with the fixing member is smaller than the inner diameter of the pigeon that is in contact with the suspended portion The water fetching bucket will be the means to solve the problem.

  According to the configuration of the present invention, the portion of the tightening string that is disposed inside the opening includes the drawing restricting body that penetrates the tightening string, and the outer dimension of the drawing restricting body is the tightening string. By making it larger than the inner diameter of the through hole, the drawing restriction body does not come out of the bucket body when water is pumped, and the opening of the bucket body is kept constant by both ends of the drawing restriction body. The above diameter reduction is prevented.

Then, when the water-bucket is placed after being pumped up, the opening, which has been slightly reduced in diameter, is returned to the expanded state by the rebound resilience of the resilience elastic material attached to the periphery of the opening and the weight of the water drawn.
For this reason, the water fetching bucket can be opened without performing any work.

  In addition, the drawing restricting body is provided in a portion of the tightening string that is disposed inside the opening, so that the diameter of the opening of the bucket main body is prevented from being reduced more than a certain value, and is attached to the periphery of the opening. The rebound resilience due to the rebound resilience material and the subsequent restoration expansion due to the weight of the pumped water does not place an excessive burden on the deformed part of the fabric where the diameter is repeatedly reduced and expanded, and the durability of the water pumping bucket is increased. Can be improved.

  Furthermore, according to the configuration of the present invention, the opening at the upper part of the bucket body is mainly deformed when water is drawn, and the deformation also reduces the resistance at the time of pumping, while the opening restrictor restricts the opening by both ends. In order to prevent diameter reduction beyond a certain level, it is possible to secure a sufficient capacity when pumping water, and it is possible to stably pump a sufficient amount of water with a single pump.

  Further, according to the invention according to claim 2, in addition to having the above-described effects by assuming the configuration of the invention, the fixing portions are provided at the left and right side positions of the tightening string exposed to the outside of the bucket body other than the suspended portion. Therefore, the side surface of the bucket body other than the hanging portion is prevented from losing the weight of water and deforming outward. Further, the distance between the fixing members, that is, the length of the tightening cord between the fixing members is equal to or less than the distance between the holes where the fixing portion approaches or abuts at both ends of the tightening cord, By preventing the loosening of the tightening string between the fixing members, the tightening string is pulled as the pulling string is pulled, and a component force acts so that the fixing members in the same wall portion are relatively separated from each other. When the fixing member presses each drawing restricting body via the constituent fabric, the load on the drawing restricting body by the fixing portion can be reduced by the laces between the fixing portions. For this reason, the durability of the water fetching bucket including the drawing restriction body can be improved. In addition, a more stable state can be ensured when drawing water.

  According to the invention according to claim 3, on the premise of the configuration of any one of the above inventions, the restoring edge portion is provided with a resilience elastic material along the inner edge of the opening of the bucket body, and is a sheet member for an edge frame. Since the rebound elastic material and the opening edge of the bucket body are integrally covered, the rebound elastic material can exert rebound resilience depending on the position of the inner edge of the opening, in addition to the effects of any one of the above inventions. Since the impact resilience material is protected by the edge frame sheet member, the impact resilience material does not fall outside, and the durability can be further improved. Moreover, since the impact resilience material is not exposed to the outside, the appearance can be improved.

  According to a fourth aspect of the present invention, on the premise of the configuration of any one of the above inventions, the hole portion is made up of eyelets, and the inner diameter of the eyelets that are close to or in contact with the fixing member has an eyelet that makes contact with the suspended portion. Since the inner diameter is smaller than the inner diameter, the effect of any of the above-described inventions can be obtained, and the eyelet contacting the suspended portion is made larger in diameter so that the eyelet contacting the suspended portion can be tightened smoothly. The string is allowed to pass through, so that the suspended state can be quickly realized, and the inner diameter of the eyelet close to or in contact with the fixing member is made relatively small, so that when the eyelet is drawn at the contact part with the eyelet As having a slight resistance, it is difficult to give a direct impact to the drawing restricting body directly, and further, the durability including the drawing restricting body is improved, and the balance between them is improved. Easier to use It is possible to combine the durability and.

It is less than the distance, and it is assumed that the tightening string does not loosen in the state of drawing water, so that the tightening string between the fixing parts can reduce the load on the drawing restriction body by the fixing parts, Realizes an excellent water pumping bucket that prevents the side of the bucket body other than the suspended part from losing its weight and deforms to the outside, making the water pumping bucket more stable. did.

  As shown in FIGS. 1 to 3, a water-drawing bucket according to an embodiment of the present invention includes a bucket body 10 having a substantially circular outline in plan view, and a fastening attached to the vicinity of an opening 11 above the bucket body 10. It is the structure provided with the string 2 and the pull string 4 connected with this tightening string 2.

  The bucket body 10 includes a substantially circular bottom surface portion 100 and a wall portion rising from the circumference of the bottom surface portion 100 (for convenience, the front wall portion 101, the rear wall portion 102, the left wall portion corresponding to the front, rear, left and right directions of the peripheral wall). 103 and the right wall portion 104. Also, in the drawing, the boundary is indicated by a two-dot chain line in FIGS. 1 to 3, and an opening 11 is formed at the upper end. .

As shown in FIGS. 1 to 4, the opening 11 is provided with a rebound elastic material 110 made of a band-shaped polycarbonate along the inner peripheral edge of the component 10 a that is the edge of the opening of the bucket body 10. Both the elastic member 110 and the constituent member 10a of the bucket body 10 are configured to include the restoration edge portion 12 covered with the edge frame sheet portion 111.
A weight 5 having a weight of about 70 g is attached in the vicinity of the opening 11 on the outer surface side of the rear wall portion 102 of the bucket body 10.

A total of two eyelets 30 forming a hole 3 for passing the fastening strap 2 are provided on the left and right sides below the restoring edge 12 of each of the walls 101, 102, 103, 104. The eyelet 30a of the front wall portion 101 and the rear wall portion 102 is a small-diameter eyelet, the eyelet of the left wall portion 103 and the right wall portion 104 is a large-diameter eyelet 10b, and the inner diameters of the eyelets 30 of the opposing wall surfaces match. Yes.
In this embodiment, an eyelet having an inner diameter of 5 mm is used as the small diameter eyelet 30a, and an eyelet having an inner diameter of 8 mm is used as the large diameter eyelet 30b.

  The fastening string 2 of the water fetching bucket 1 according to the present embodiment is constituted by a single fastening string material 2a. The fastening material 2a passes the above-described eyelets 30a and 30b alternately on the outer side and the inner side of the bucket body 10, and goes around the bucket body 10 to connect both ends, and the left wall portion 103 and the right wall portion Between the eyelets 10b and 10b of 104, the fixing tool 6 is attached and the small loop 20 is formed to constitute a connecting means with the drawstring 4.

  The drawstring 4 in the present embodiment is formed by forming small loops 40 at the center and both ends. The small loops 40 at both ends constitute the small loop 40 after the string material of the drawstring 4 is passed through the small loop 20 of the tightening string 2 of the left wall portion 103 and the right wall portion 104 to be connected. Note that each of the small loops 20 and 40 in the present embodiment has a configuration in which a ring is formed so that the tip of the string member is folded back and fixed by metal fittings 21 and 41, respectively.

  The strap 2 is attached through the eyelet 30 so as to be exposed to the outside of the wall portions 101, 102, 103, 104 between the left and right eyelets 30, 30 of the wall portions 101, 102, 103, 104. It is assumed that between the eyelets 30 and 30 of the adjacent wall portions 101, 102, 103, and 104, the tightening cord 2 is disposed in the water fetching bucket 1. A drawing restricting body 7 through which the tightening string 2 is passed is provided in a portion of the tightening string 2 that is disposed between the eyelets 30 and 30 in the water drawing bucket 1. The drawing restricting body 7 is a hard synthetic resin tubular body having an inner diameter of 6 mm and a length of about 25 mm. In the drawing restricting body 7 according to the present embodiment, the difference between the inner diameter dimension and the outer dimension is set to be small so as to suppress the overall thickness, thereby reducing the cost and weight of the raw material.

  In addition, the fixing portions 6 are provided on both the left and right positions of the tightening string 2 exposed to the outer sides of the front wall portion 101 and the rear wall portion 102 of the bucket body 10 other than the hanging portion 22 of the tightening string 2. The fixing portion 6 in this embodiment is formed by caulking and fixing a metal plate material having a length of about 10 mm around the fastening string 2. The fastening string 2 is continuous between the left and right fixing portions 6 and 6 of the front wall portion 101 and the rear wall portion 102. The length of the lace 2 in the section is smaller than the distance between the eyelets 30a and 30a that are adjacent to or in contact with the left and right, and does not sag in a state where water is drawn and the pull string 4 is loaded. ing.

In the present embodiment described above, the outer diameter d1 of the drawing restricting body 7 is larger than the inner diameter d3 of the large eyelet 30b. The minimum width w1 of the fixed portion is larger than the inner diameter d4 of the small-diameter eyelet 30a.
Further, the diameter of the tightening cord 2 is smaller than any of the inner diameter d2 of the drawing restriction body, the inner diameter d3 of the large diameter eyelet 30b, and the inner diameter d4 of the small diameter eyelet 30a. (See Figure 7.)
If the surface of the tightening cord 2 has some elasticity or flexibility, the diameter of the tightening cord 2 and the inner diameter d4 of the small eyelet 30a can be made the same.

  With the above configuration, when the water fetching bucket 1 according to the embodiment of the present invention is dropped into the water while holding the pull string 4, the rear wall portion 102 having the weight 5 is inclined downward, The water fetching bucket 1 sinks into the water, water enters the water fetching bucket 1, and the water fetching bucket 1 is filled with water.

  After the water pumping bucket 1 is filled with water, the pulling string 4 is pulled up to pull up the water pumping bucket 1. As shown in FIG. 6, the water-drawing bucket 1 at the time of pulling up starts the diameter reduction with the opening 11 being squeezed by the weight of the pumped-up water and the pulling force of the drawstring 4. By reducing the diameter, it is possible to obtain the effect of the prior art that can greatly reduce the catch of the water pumping bucket due to contact with a rocky place or the like when pumping water.

  As the diameter decreases, both ends 70 of the drawing restricting body 7 arranged inside the opening 11 abut against the peripheral component 10a, so that the eyelets 30a and 30b of the adjacent wall portions are mutually connected. The deformation of the constituent material 10a is suppressed, and the degree of diameter reduction is limited. For this reason, the component material 10a is prevented from being excessively reduced in diameter, and the component material 10a is prevented from being bent, and consumption of the component material 10a due to repeated reduction and diameter expansion of the opening 11 is prevented. Reduce significantly.

  Moreover, since the fixing | fixed part 6 is provided in the right-and-left both-sides position of the fastening cord 2 exposed to each outer side of the front wall part 101 and the rear wall part 102 of the bucket main body 10 as above-mentioned, it pulls the pull string 2 and suspends it. In the lowered state, the fixing portion 6 abuts against the eyelets 30 and 30 and is strongly pressed against the constituent material 10a, and further, the length of the lace 2 between the fixing portions 6 and 6 is left and right eyelets. Since the length is smaller than the distance between them and the length of the tightening cord 2 is not slackened when water is drawn, a part of the local load applied to the fixing portion 6 is released to the tightening cord 2. It is possible to improve the stability and durability of the water fetching bucket 1 and to prevent the front wall portion 101 and the rear wall portion 102 from being accidentally opened to the outside.

  Then, when the water pumping bucket 1 according to this embodiment is placed on the ground in a state where water is pumped, the weight of the pumped water and the resilience elasticity of the restoring edge 12 provided at the opening edge as shown in FIG. Thus, the opening 11 is easily expanded in diameter and restored to the initial shape. For this reason, the water drawn without performing any operation can be used immediately, and the convenience can be dramatically improved as compared with the conventional case.

  As described above, the embodiments of the present invention have been described. However, the present invention is not limited to those disclosed in the above embodiments. For example, the shape of the bucket body 10 is not limited to a substantially circular shape in plan view, but is rectangular in plan view. Etc.

In the drawing restriction body 7 according to the present invention, as described above, the inner diameter d2 of the drawing restriction body 7 only needs to have a dimension that allows the fastening string 2 to slide. The outer dimension or the minimum width dimension of the drawing restricting body 7 may be equal to or larger than the inner diameter of the eyelet 30 (that is, the dimension not passing through the eyelet hole). The shape of the drawing restricting body 7 is not limited to the tubular body shown in the embodiment, but may be any shape such as a spherical shape or other design features. On the other hand, when a tubular body is used as in the present embodiment, both end faces easily come into contact with the eyelet, and the restriction of the tightening string 2 to the drawing can be stably performed.
Furthermore, since the length of the drawing restricting body 7 greatly affects the degree of deformation of the constituent material 10a of the bucket body 10, it may be determined according to the size of the water fetching bucket 1 or the like.
In addition to the synthetic resin described above, the drawing restricting body 7 may be made of a metal material, for example, and exhibits a strength that does not cause deformation of the aperture 11 of the tightening cord 2. It is desirable to be able to do it. However, the drawing restricting body 7 according to the present invention is only required to prevent the diameter of the opening 11 from being reduced more than a certain value even if it is slightly deformed.

  In addition, the fixing portion 6 in the present invention is not limited to the one in which the metal plate material shown in the embodiment is caulked and fixed, as long as it can be secured not to come out from the hole portion 3. Alternatively, it may be configured by welding resin or forming a knot by the lace 2 itself.

  Further, in the present invention, the tightening string 2 and the pull string 4 are connected to each other by the small loops 20 and 40, but the present invention is not limited to this structure, Various known connecting means such as fixing with a metal fitting or the like can be used.

  Further, in the present invention, if the inner diameter of the eyelet 30 is equal to or larger than the diameter of the tightening string 2 (for example, about 5 mm inner diameter), the eyelet 30 (relatively small eyelet 30a and large diameter eyelet 30a). When the eyelet 30b is used, the drawing restricting body 7 larger than the inner diameter of the large eyelet 30b) can be substantially reduced, so that each eyelet 30 (small diameter eyelet 30a, large diameter eyelet 30b) and the drawing eye. The cost of the regulating body 7 can be reduced.

  In addition, in the case of a substantially large eyelet, especially when the component of the bucket body is pulled sideways, the dough slips and the eyelet tends to fall off the component, so that the eyelet has a substantially smaller diameter. As a result, the possibility of such dropout can be reduced, and the durability of the bucket body can be improved.
