Description

    The present invention relates to a weeding scoop having a weeding function for easily removing weeds and the like.

    Scoops are used to care for gardens and flower beds, and are easily used for planting, digging, and leveling.

    On the other hand, weeds and trees that grow there are fast growing and need to be removed as needed. There is a limit to pulling this out by hand. Even if it can be pulled out, if it spreads extensively, it will not be possible to bear the burden on the worker.

    Such weeding has traditionally been cut with a bite or mower, or with a herbicide all at once, but these methods can no longer be replanted. In order to excise the stem with the root remaining, it regenerates relatively early and may damage nearby useful plants. On the other hand, the method using the latter herbicide hurts the soil itself and has a problem in the natural environment.

    For example, Patent Document 1 includes a plate-like piercing portion 1 with a sharp tip and a handle provided at the base end thereof, and is directed to the base end portion from the tip of the piercing portion. Thus, a weeding tool having a plurality of slits 5 is disclosed.

Patent Document 2 describes a weeding tool including a gripping member and a main body having a base fixed to the gripping member.
The main body has a grass catching portion that has a substantially uniform thickness, has a grass supplementary space that expands substantially rearward by a hook-shaped protrusion on the side of the tip portion, and has substantially the same thickness as the entire main body. The weeding tool characterized by this is disclosed.

Japanese Patent Application Laid-Open No. 2011-30 Utility Model Registration No. 2536257

    However, each of the weeding tools according to each of the above patent documents pierces the tip of the weed toward the weed stalk, and because the stalk of the weed receives a lateral force due to its insertion or pulling at the time of withdrawal, There is a risk of cutting easily. For this reason, the roots remaining in the ground can no longer be easily removed, which requires more time than necessary, for example, digging a larger hole.

    In view of the problems of such a conventional weeding tool, the present invention has been obtained by contrivance and trial for improvement thereof, and it is easy and easy to take advantage of weeds that are deeply rooted deeply. The purpose is to provide a weaving scoop that can be removed.

That is, the invention according to claim 1 of the present application is
A scoop having a plate-like body projecting outward on the distal end side, and a handle integrally provided on the proximal side of the plate-like body,
The plate-like body includes a non-flat bottom surface for forming a fulcrum when the lower surface side comes into contact with the ground, and a recess for holding weeds on the overhanging outer edge portion,
The recess has a trumpet-shaped or funnel-shaped opening shape that spreads at a wide angle toward the outside of the outer edge portion, and the opening has a width dimension (L) that is equal to or larger than the stem portion of the weeds. A combined scoop for weeding.

Further, the invention according to claim 2 according to the use form is characterized in that the recess has a plurality of different frontage shapes and / or opening dimensions (L) along the projecting outer edge, and is located on the tip side. The opening size is so small that
In the invention according to claim 3, the non-flat bottom surface is formed by a bulge portion formed by bending the plate-like body in the vertical direction and the horizontal direction so as to cause a lever action by pushing down and twisting the handle at the same time. Being
The invention according to claim 4 is the weeding and scooping scoop characterized in that at least the edge portion on the upper surface side of the recess is constituted by a rounded round edge.

According to the invention of claim 1 of the present application,
The scoop uses a plate-like body with an overhanging outer edge projecting outward on the tip side, and a recess for holding weeds is provided on the outer edge, and its bottom surface is made non-flat Therefore, the retained weeds are pulled up almost directly by the lever action and can be easily removed without cutting the stem.

  Moreover, since the scoop is a plate-like body having a relatively thin thickness, and the recess is provided at a wide angle on the outer edge protruding outward, it can be easily held against weeds having a relatively low height, It has versatility that can be used as a general scoop, can be used for many purposes, and there is no need to prepare a separate instrument for each operation.

Further, according to the invention according to claim 2, the recess is provided with a plurality of shapes and sizes, and is smaller at the tip side so that it is easy to operate, and the type and size of weeds, or the vegetation state thereof. Can be selected as appropriate, and can be used as it is without having to change another tool.
According to a third aspect of the invention, the lever action can be simultaneously pushed down and twisted by the non-flat bottom surface of the bulging portion, so that the place of use is not limited. Further, according to the invention according to claim 4, since the upper surface side of the recess is constituted by a rounded round edge, the stem portion may be cut carelessly when the weed is removed. Can be prevented.

  It is a perspective view which shows one form of the scoop for weeding concerning this invention.   It is a schematic diagram explaining the lever action at the time of weeding.   It is an enlarged view which shows an example of a recess.

Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
As described above, the present invention is composed of the plate-like body 2 having the projecting outer edge portion A projecting outward on the distal end side, and the handle 3 provided on the proximal side thereof,
The plate-like body 2 has a non-flat bottom surface so as to form a fulcrum S when the lower surface thereof is in contact with the ground, and is provided with a recess 4 for holding weeds on the overhanging outer edge A, and on the outside thereof. A scoop 1 having a trumpet shape or a funnel shape widening toward the wide angle and a weeding scoop 1 having an opening size L larger than a stem portion for accommodating weeds is targeted.

FIG. 1 is a perspective view showing one form thereof.
The scoop 1 includes a plate-like body 2 that has the outer edge portion A and is appropriately bent by bending, and the scoop 1 including a handle 3 that is integrally provided on the proximal side thereof. Both are formed of the plate-like body. The plate-like body 2 is made of a ceramic material such as an iron plate, plastic, or ceramic, for example, a plate thickness having a predetermined strength and a size that can be manually operated, for example, a length of 300 mm or less and a thickness of about 5 mm or less. Consists of.

  The plate-like body 2 is formed in a ship shape so as to be a tip of a blade with a sharpened tip side, and has a protruding outer edge having a contour inflated while being refracted in an arc shape or in small increments so as to project outward. A recess 4 for holding weed for holding the weed to be removed is provided along the part A and the outer edge A. In addition, the said overhang | projection outer edge part A means the part in which the apparent outline of a plate-shaped object is in the state swelled outside in this way.

  In addition, the other hand side of the plate-like body 2 is provided with a handle 3 by molding the plate-like body or as a single unit, like a general scoop, and the operator can freely operate the handle 3. The optimum use is made.

  In the present embodiment, the outer edge portion A is provided in a range having a longitudinal length of about ½ from the front end side of the plate-like body 2, and a plurality of the recesses having different sizes along the outer edge portion A. 4a, 4b... Are arranged. In that case, the concave portion 4 is arranged so that the one located on the tip side is smaller and is made larger toward the hand side, so that the operator does not bother to change according to the type, thickness and location of the weeds. These are properly used by selecting an arbitrary recess 4.

  Since the plate-like body 2 is configured to have a wide bottom surface as seen in the figure, the fulcrum S portion is effective without sinking even when applying a lever action for removing weeds. The lever action is obtained. Further, the structural strength deficiency can be improved by making the tip side the smaller recess 4a, and it can be used as it is for digging as a normal scoop.

  If necessary, the plate-like body 2 can be constituted by the projecting outer edge A on the entire periphery, and the recess 4 can be provided over the entire periphery. The present invention can be applied to various forms within the scope of the invention idea, such as being provided on only part of the side surface.

  When the scoop 1 is placed in contact with the ground surface, the scoop 1 may be bent and deformed non-flatly, for example, by bulging the bottom surface into a ball shape so as to create a lever fulcrum S for the lever action on the lower surface side. Alternatively, the fulcrum S is formed by attaching the handle 3 with a certain angle.

  In this embodiment, the plate-like body 2 that is largely bent into a toy shape as a whole is used, and further, the ball-shaped bulging portion C having bulges in the vertical and horizontal directions is formed by slightly inflating the vicinity of the center. Forming.

  With such molding, when the lever action is obtained by, for example, pushing down the handle 3, a slightly large recess 4 provided on the side of the scoop 1 by the bent portion in the vertical direction and on the weed with a relatively thick stem is used. When the handle 3 is pushed and / or twisted simultaneously, the weeds are lifted almost directly by their lever action, and the stem may be cut or the root may remain. It is reduced.

  In this way, by pushing down or twisting the handle 3 on the hand side, a lever action in a free direction such as an oblique direction is brought about, thereby expanding the application range, and the fulcrum S part is located slightly away from the weeds. Therefore, it is possible to prevent the weeds from being directly pressed and the ground from being squeezed, and there is also a convenience in which any recess 4 can be selected according to the location, which contributes to reducing the burden on the operator. FIG. 2 shows an example of the extracted state, and the fulcrum S is preferably provided, for example, near the tip side of the scoop or near the center so that a more effective lever action can be obtained.

Next, the recess 4 will be described.
As described above, the recess 4 is provided at a predetermined position on the line along the contour line of the overhanging outer edge A, and has a trumpet shape or funnel shape so that the front end portion is widened toward the outside. And an opening size (L) larger than that of the stem portion of the weeds.

FIG. 3 shows an enlarged view of the recess 4 so that the opening angle θ becomes an obtuse angle. As can be seen, the notch is gradually widened toward the outside. The angle θ is set large. The angle θ is, for example, an obtuse angle of 90 ° or more, and can be configured as an arcuate arc surface or a refracting surface bent in small increments as the trumpet shape or funnel shape so that weeds can be easily stored. It can also be formed by a composite surface in which these are appropriately combined.

    In that case, the frontage angle θ may be formed to be a smooth surface, more preferably 140 ° or more, and the recess 4 has a frontage dimension L so that a stem portion of weed can be fitted. Is less than the thickness of the weed stalk, for example, about 5 to 80 mm, and the depth H is preferably set to 1.2 times or less of the frontage dimension L.

  In the case where the opening dimension L is smaller than 5 mm, it is unreasonable to take time to store the stem portion of the weed Z in the recess 4, and conversely, it is unreasonable to exceed 80 mm, preferably 8 to 60 mm. More preferably, it is 10 to 40 mm, and in particular, the recess 4 on the tip side of the scoop 1 is recommended to have a relatively small opening dimension L of about 5 to 20 mm.

  Further, when the formation depth H is larger than 1.2 times, it takes time to remove the weeds after the removal and the material strength is inferior in terms of structure, more preferably 0.5 to 1 times. The optimum range is selected so that the depth is about a certain degree.

  FIG. 3 shows the recess 4 having two shapes 4c and 4d different in size from the shape. For example, the scoop has a predetermined r so that a relatively small recess is formed on the tip side of the scoop. By making a trumpet shape with an arc surface, the width of the notch decreases along the arc surface, so that weed retention is improved compared to a linear one like the funnel shape, Moreover, since the formation depth can also be made small, it is preferable to provide in the front end side especially.

  On the other hand, since the plate-like body is wide at the rear end side of the scoop, even if a slightly large recess is provided, there is little substantial decrease in strength. It is also preferable to arrange them side by side.

  In this way, the scoop 1 of the present invention can be used in addition to, for example, mugwort, Japanese horsetail, stag beetle, daio,... It can also be used effectively for densely weeds such as Japanese pampas grass and so on, in which case the opening 5 is not less than 0.8 times the dense thickness, for example, 0.8 to 10 times the frontage Those with dimensions (L) are selected. In particular, since the plate-like body 2 is composed of a plate material having a relatively thin thickness t, even if the weeds are low in height, such as nazuna, psyllium, etc. It can be inserted into the recess 4.

  Further, the recess 1 has a predetermined depth so that the front end portion 5 has a smooth wide angle. The weed Z can be easily fitted into the inside thereof, and the weed Z accommodated therein is shown in FIG. Thus, it can be securely held by simply pinching it with fingers U or pressing it lightly, and it is easy to remove it after removal.

  In such an extraction method, it is preferable that at least the upper edge portion has a rounded edge as shown in FIG. 3 so that the recess 4 accommodates the weed Z and does not cut when the weed Z is extracted. . The figure shows two recesses 4c and 4d having round edges including their upper and lower surfaces, 4c is a trumpet shape with a radius of curvature r, and 4d is the same as described above so that the frontage angle θ becomes a wide angle. Shows a funnel shape following the arc.

  The scoop 1 is configured in this way. When this scoop 1 is used for weeding, as described above, the scoop 1 is selected with the optimum recess 4 for the stem portion of the weed Z, and the stem portion of the weed is fitted therein. The weed Z is pulled up and removed by the lever action only by pushing down or twisting the handle 3 while being put in and held. In that case, since the recess is provided in the overhanging outer edge portion, all the recesses can be used by changing the arrangement angle of the scoop for each recess.

    Moreover, since the scoop is composed of a relatively wide plate-like body, the installation area can be set large with respect to the ground. Therefore, even if this is applied with a strong force, it can be prevented from sinking into the ground. At that time, the weed Z is not subjected to a lateral force, and the cutting of the weed Z is reduced, and the production can be obtained in the same manner as a conventional commercial scoop, and the application range is not limited.
