Description

The present invention relates to a scoop and bait system.

A baiting method for preventing and exterminating termites is known (see, for example, Patent Document 1). In this method, bait stations containing bait logs are installed underground at multiple locations around a building, and when periodic inspections confirm that the bait logs have been eaten by termites, the logs are replaced with bait containing chemicals. Ultimately, the termites carry the bait back to their nest, where it spreads throughout the nest, eradicating the termites.

Japanese Patent Application Laid-Open No. 2021-123993

The bait station has an opening that connects the inside and outside of the station, allowing termites to access the inside of the station. Because of this opening, surrounding soil and stones (hereinafter referred to as "soil, etc.") may enter the bait station.

Inspecting the lures in a bait station and replacing them with bait requires removing the lures from the bait station. When replacing lures after removing them from the bait station, or when replacing lures with bait, it is necessary to scrape out soil and other debris from the bait station. However, because bait stations are small and deep, scraping out soil and other debris from bait stations is not easy. This is particularly true when multiple bait stations are installed, as it is necessary to scrape out soil and other debris from each bait station, making the process even more time-consuming.

The objective of the present invention is to provide a shovel and bait system that makes it easier to remove soil and other materials from a bait station.

One aspect of the present invention is
a handle portion extending in a first direction;
a scooping portion provided at a first end portion of the handle in the longitudinal direction,
the scooping portion has a bottom plate extending in a direction intersecting the first direction, and a back plate extending in the first direction from one of the peripheral edges of the bottom plate and connected to a tip of the handle portion ,
the bottom plate has a normal line extending in a direction perpendicular to the surface thereof and an angle between the normal line and the first direction of 30° or less;
In a plan view, the bottom plate has an edge portion opposite to the edge portion on which the back plate is provided, which has an arc shape that protrudes toward the opposite side from the back plate.
Provide a scoop.

This invention has a base plate with a normal that is no more than 30° to the extension direction of the handle, so when the handle is inserted into the hole along the depth direction, the scooping part at the tip can easily scoop up and scrape out the deposits at the bottom of the hole.

Another aspect of the present invention is
A cylindrical bait station installed underground,
The scoop is inserted into the inside of the bait station,
The bottom plate has a radius of curvature of the opposite edge that is smaller than the inner diameter of the bait station.
Provide a bait system.
Furthermore, still another aspect of the present invention is
A cylindrical bait station installed underground,
The scoop is inserted inside the bait station;
Equipped with
The bait station has a through hole at the bottom,
The scooping portion is capable of passing through the through hole .
Provide a bait system.

A bait system 1 according to one embodiment of the present invention will now be described with reference to the accompanying drawings. Please note that the following description is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

Figure 1 is a perspective view that shows a schematic diagram of a bait system 1 according to one embodiment of the present invention. As shown in Figure 1, the bait system 1 includes a bait station 10 that is installed underground, and a lure 4 housed within the bait station 10, or a bait material 5 housed in place of the lure. Note that Figure 1 shows a portion of the bait station in a see-through view, and a portion of the lure 4 in a cross-sectional perspective view.

The bait station 10 is a bottomed cylindrical member with an upper opening 11, a bottom 12, and a cylindrical outer periphery 13. In this embodiment, the bait station 10 has an inner diameter of 80 mm and a depth of 300 mm from the opening 11 to the bottom 12. A lid member 14 is removably attached to the opening 11. The bottom 12 has a circular bottom opening 12a that penetrates vertically. The outer periphery 13 has multiple slits 13a that penetrate radially.

The bait log 4 is made of wood that termites like to eat (e.g., aspen or red pine) and is stored within the bait station 10 to monitor whether or not termites are present in the surrounding area. The bait material 5 contains chemicals that eradicate termites. If an inspection of the bait log 4 confirms the presence of termites, the bait material 5 is stored within the bait station 10 in place of the bait log 4. The bait log 4 and bait material 5 are cylindrical and fit along the inner diameter of the bait station 10.

The bait station 10 is installed underground so that the opening 11 (lid material 14) is visible above ground surface S. The bait station 10 also has a cavity 42 in the ground below the bottom opening 12a. The bait station 10 is configured so that termites can enter through the slits 13a and/or bottom opening 12a to access the bait 4 or bait material 5.

The bait system 1 according to this embodiment further includes a shovel 7, which is used to scrape out soil and/or remove plant roots that have infiltrated the bait station 10 when inspecting the lures stored in the bait station 10 and when replacing them with bait material.

Figure 2 is a perspective view of the shovel 7 alone. As shown in Figure 2, the shovel 7 has a long handle 20 and a scooping portion 30 attached to the lower end (tip) of the handle 20. In this embodiment, the shovel 7 is constructed by bending a 1 mm thick steel plate (for example, stainless steel may be used for rust prevention) and welding a portion of the scooping portion 30 to the plate. Alternatively, the shovel 7 can be constructed using various methods, such as casting or forging.

In the following description, with regard to the directions of the scoop 7, the extension direction of the handle 20 is referred to as the first direction X, the direction in which the bottom plate 31 (described later) of the scooping portion 30 extends, which is perpendicular to the first direction X, is referred to as the second direction Y, and the width direction of the scooping portion 30, which is perpendicular to the first direction X and the second direction Y, is referred to as the third direction Z. With regard to the first direction X, the upper side in the figure is referred to as the X1 side, and the lower side in the figure is referred to as the X2 side. With regard to the second direction Y, the diagonally downward right in the figure is referred to as the Y1 side, and the diagonally upward left in the figure is referred to as the Y2 side. With regard to the third direction Z, the diagonally upward right in the figure is referred to as the Z1 side, and the diagonally downward left in the figure is referred to as the Z2 side.

The handle 20 has a tip 21 at its X1 end (base end). Figure 3 is a front view of the tip 21. As shown in Figure 3, the handle 20 has a width W1 in the Z direction that is approximately constant across the X direction, excluding the tip 21. The tip 21 is rounded and tapered so that its width in the Z direction decreases toward the X1 side. The width W1 of the handle 20 is set to make it easy for the user to grip, and is 26 mm in this embodiment.

Figure 4 is a cross-sectional view perpendicular to the extension direction of the handle 20 taken along line IV-IV in Figure 3. As shown in Figure 4, the handle 20 has an arc-shaped cross-section (concave cross-section) that is concave on the Y2 side. By configuring the handle 20 with a concave cross-section, the bending rigidity of the handle 20 in the second direction Y can be improved across the first direction X, and soil, etc. can also be held on the Y1 side of the handle 20. Furthermore, by configuring the handle 20 with an arc-shaped cross-section, the handle 20 can be easily fitted to the palm of a user holding it, improving grip by the user.

Referring to Figure 2, the scooping portion 30 has a bottom plate 31, a back plate 32, and a pair of side walls 33. The bottom plate 31 is located at the X2 end and extends in a direction intersecting the first direction X. The bottom plate 31 is located on the Y1 side of the back plate 32 and the handle portion 20.

The back plate 32 extends from the Y2 end of the periphery of the bottom plate 31 toward the X1 side and is connected to the X2 end of the handle 20. The back plate 32 extends parallel to the first direction X. In this embodiment, the back plate 32 is formed in a flat shape parallel to the first direction X and the third direction Z. Alternatively, the back plate 32 may be formed in a curved shape that is concave toward the Y2 side so as to be continuous with the cross-sectional shape of the handle 20.

The pair of side walls 33 extend toward the X1 side from both edges of the periphery of the bottom plate 31 that sandwich the back plate 32 in the Z direction, and are connected to the side edges of the back plate 32. The pair of side walls 33 are formed in a rectangular shape that is long in the X direction.

Figure 5 is a side view of the scooping unit 30 as viewed from the Z direction. As shown in Figure 5, in this embodiment, the bottom plate 31 extends in a direction perpendicular to the first direction X. Specifically, the bottom plate 31 extends in the second direction Y. In other words, the normal line V1 of the bottom plate 31, which extends perpendicular to the surface, extends parallel to the first direction X. The corners of the pair of side walls 33 on the X1-Y1 side are rounded.

Figure 6 is a cross-sectional view of the scooping portion 30 taken along line VI-VI in Figure 5, perpendicular to the first direction X. As shown in Figure 6, the bottom plate 31 has an edge portion 31a formed in an arc shape that is convex toward the Y1 side at the Y1 side edge. The radius of curvature R1 of the edge portion 31a is preferably set smaller than the inner diameter R0 of the bait station 10 (shown by the two-dot chain line in Figure 6). Furthermore, the bottom plate 31 is formed so as to be smaller than the bottom opening 12a of the bait station 10.

Next, with reference to Figures 7 to 9, a method of using the bait system 1 will be explained. First, with reference to Figure 7(a), a bait station installation hole 41 is excavated at the installation location where the bait station 10 will be installed, and the bait station 10 is installed underground in the bait station installation hole 41. Next, a pair of upper and lower baits 4 are placed inside the bait station 10, and the opening 11 is closed with a lid 14. When the bait station installation hole is excavated, a hollow portion 42 with a smaller diameter than the bait station installation hole is also excavated below the bait station installation hole.

Next, leave the bait system 1 for a while to check whether the bait 4 is eaten by termites that may be present in the vicinity. At this time, as shown in Figure 7(b), soil G from around the bait station 10 may enter and accumulate inside the bait station 10 through the slits 13a, and roots T of plants and trees located around the bait station 10 may also enter the bait station 10. At this time, surrounding soil G may also accumulate in the space 42 below the bait station 10.

Next, when the lure 4 is removed from the bait station 10 for regular inspection, the soil G that had accumulated around the lure 4 accumulates at the bottom of the bait station 10. As a result, as shown in Figure 7(c), when the lure 4 is removed, in addition to the soil G that has accumulated at the bottom, roots T of plants and trees extend through the slits 13a inside the bait station 10. In this state, the soil G that has accumulated at the bottom and the roots T of plants and trees that extend inside get in the way, preventing the lure 4 or, in place of the lure 4, bait material 5 from being placed inside the bait station 10.

In this embodiment, the bait system 1 is equipped with a scoop 7, and as shown in Figure 7(d), the scoop 7 can be used to scrape out soil, etc. G, that has accumulated on the bottom. Specifically, the scoop 7 has a bottom plate 31 in which the scooping portion 30 extends in a direction perpendicular to the extension direction of the handle portion 20. Therefore, the handle portion 20 can be inserted into the bait station 10 with the handle portion 20 aligned along the depth direction of the bait station installation hole 41, and the scooping portion 30 at the tip can be used to scoop out and scrape out soil, etc. G, that has accumulated on the bottom.

Furthermore, as mentioned above, the bottom plate 31 of the scooping unit 30 is smaller than the bottom opening 12a of the bait station 10. Therefore, as shown in Figure 8(a), the scooping unit 30 can pass vertically through the bottom opening 12a of the bait station 10 to access the space 42, so that soil G accumulated in the hollow portion 42 can also be scraped out by the scooping unit 30.

Next, as shown in Figure 8(b), the edge portion 31a of the scooping unit 30 is moved up and down along the inner wall surface of the bait station 10, so that the edge portion 31a can cut the roots T of plants extending into the bait station 10 through the slits 13a at the inner wall surface of the bait station 10. The cut roots T can be scooped up and scraped out of the bait station 10 using the bottom plate 31, just like the soil G.

As a result, as shown in Figure 8(c), soil G and plant roots T can be removed from inside the bait station 10, and as shown in Figure 8(d), for example, if the bait log 4 has not been eaten by termites, the bait log 4 can be returned to the bait station 10, or if the bait log 4 has been eaten by termites, the bait material 5 can be placed inside the bait station 10 in place of the bait log 4.

Figure 9 shows a schematic diagram of the scraping operation of soil, etc. G, within the bait station 10 using the tip 21 of the handle 20. For example, if the soil, etc. G accumulated within the bait station 10 is hard and difficult to scrape out using the scooping portion 30 of the shovel 7, the tapered tip 21 can be used to loosen the soil, etc. G, as shown in Figure 9(a).

Also, as shown in Figure 9(b), if the soil G accumulated inside the bait station 10 is wet, the soil G can also be scooped up using the Y1 surface of the handle 20, which has a concave cross section. Therefore, soil loosened using the tip 21 can be scooped up directly using the handle 20. Note that if the soil G is dry and difficult to scoop up using the handle 20, as shown in Figure 9(c), water M can be added to the soil G accumulated inside the bait station 10 to moisten the soil G and make it easier to scoop up.

Also, as shown in Figure 9(d), the tapered tip 21 may be used to cut roots T of plants and trees extending into the bait station 10.

The bait system 1 described above provides the following advantages:

(1) The scoop 7 includes a handle 20 extending in the first direction X and a scooping portion 30 provided at the X2 end of the handle 20. The scooping portion 30 has a bottom plate 31 extending in a direction perpendicular to the first direction X.
As a result, since the scooping portion 30 has a bottom plate 31 that extends in a direction perpendicular to the extension direction of the handle portion, the handle portion 20 can be inserted into the bait station 10 along the depth direction, and the scooping portion 30 at the X2 side end can easily scoop up and scrape out deposits of soil, etc. G at the bottom.

(2) The scooping portion 30 includes a back plate 32 that extends in the first direction X from one of the peripheral edges of the bottom plate 31 and is connected to the tip of the handle portion 20 .
As a result, the scooping unit 30 is configured to be L-shaped in a side view by the bottom plate 31 and the back plate 32. Therefore, the deposit scooped by the bottom plate 31 can be easily held between the bottom plate 31 and the back plate 32, and spillage from the bottom plate 31 can be easily prevented.

(3) The scooping portion 30 includes a pair of side plates 33 that extend in the first direction X from both edges of the peripheral portion of the bottom plate 31 that sandwich the back plate 32 and are respectively connected to the side edges of the back plate 32.
As a result, a U-shaped portion is formed by the back plate 32 and the pair of side plates 33 at the periphery of the bottom plate 31. Therefore, the deposit scooped up by the bottom plate 31 can be more easily held in the U-shaped portion, and spillage from the bottom plate 31 can be more easily prevented.

(4) In a plan view, the bottom plate 31 has an edge portion 31 a formed in an arc shape on the edge opposite to the edge portion where the back plate 32 is provided, which protrudes toward the opposite side from the back plate 32.
As a result, when scoop 7 is inserted into the cylindrical hole, arc-shaped edge 31a of bottom plate 31 can be easily fitted to the inner surface of the hole, making it easier to scrape off foreign matter (soil, etc. G) adhering to the inner surface of bait station 10 or foreign matter (plant roots, etc. T) extending from the inner surface into the hole. Furthermore, when the radius of curvature R1 of edge 31a is smaller than the inner diameter R0 of bait station 10, edge 31a can more easily scrape off foreign matter adhering to the inner surface of bait station 10.

(5) The back plate 32 and the handle portion 20 are aligned in a straight line in the first direction X.
As a result, the scoop 7 is configured so that the scooping portion 30 opens upward from the bottom plate 31. This makes it easier to increase the amount of sediment that can be held by the scooping portion 30. In addition, the handle 20 and the back plate 32 can be easily formed integrally from a single plate, making it easy to form the scoop 7.

(6) The handle 20 is a plate-like member having a cross section perpendicular to the first direction X that is concave toward the Y2 side.
As a result, the concave cross section of the handle portion 20 can improve the bending rigidity in the second direction Y along the first direction X, while ensuring the ability of the handle portion 20 to scoop up soil, etc. G. Furthermore, when held by a user, the handle portion 20 can be easily fitted to the palm of the hand, making it easy to grip.

(7) The handle 20 has a tapered tip 21 .
As a result, the tip 21 of the handle 20 can be used to loosen soil G that has accumulated inside the bait station 10, and can also be used to cut roots T of plants that extend inside the bait station 10.

(8) The bait system 1 includes a cylindrical bait station 10 that is installed underground and a scoop 7 that is inserted inside the bait station 10.
As a result, soil G accumulated in the bait station 10 can be easily scraped out with the shovel 7, and furthermore, roots T of plants and trees extending into the bait station 10 can be easily cut with the shovel 7. Therefore, the workability of removing deposits in the bait station 10 is improved.

(9) The bait station 10 has a bottom opening 12a in the bottom 12, and the scooping part 30 can pass through the bottom opening 12a.
As a result, the scooping section 30 can be made to have access to the lower part of the bait station 10, making it easier to scrape out soil, etc. G that has accumulated in the hollow section 42 provided below the bait station 10.

In the above embodiment, the scooping portion 30 of the scoop 7 is configured so that the bottom plate 31 extends in a direction perpendicular to the first direction X, but this is not limited to this. The bottom plate 31 may also be configured so that the normal extending perpendicular to the surface is inclined with respect to the first direction X.

Figure 10 shows a modified bait system 50. As shown in Figure 10, the bait system 50 has the same bait station 10 as the above embodiment, but the configuration of the scoop 51 is different. The scoop 51 has a handle 52 and a scooping part 53, and the normal V2 of the bottom plate 54 of the scooping part 53 is configured to be inclined with respect to the first direction X.

Specifically, in this modified example, the normal line V2 of the bottom plate 54 is inclined at an angle of 10° relative to the first direction X. This modification makes it easier to align the bottom plate 54 of the scooping portion 53 with the bottom 12 of the bait station 10 when the scoop 51 is inserted with the handle 52 inclined relative to the depth direction of the bait station 10.

The inclination direction of the bottom plate 54 may be either toward the handle 52 (X1 side) or away from the handle 52 (X2 side). For example, in the embodiment shown in FIG. 10(a), the scoop 51 is inclined toward the X2 side so that the angle K1 between the bottom plate 54 and the back plate 55 is an obtuse angle. On the other hand, in the embodiment shown in FIG. 10(b), the scoop 51 is inclined toward the X1 side so that the angle K2 between the bottom plate 54 and the back plate 55 is an acute angle.

In the configuration shown in Figure 10(a), when the scoop 51 is inserted with the handle 52 at an angle to the depth direction of the bait station 10, the scooping part 53 can easily scoop up soil G that has accumulated near the outer periphery of the bottom 12 of the bait station 10 from the radial center to the radial outside.

On the other hand, as shown in Figure 10(b), when the scoop 51 is inserted with the handle 52 at an angle in the opposite direction to the depth direction of the bait station, the scooping part 53 can easily scoop up soil G that has accumulated near the outer periphery of the bottom 12 of the bait station 10 from the radial outside toward the radial center.

In other words, for a bait station 10 (e.g., an inner diameter of 80 mm and a depth of 100 mm), the bottom plate 54 of the scoop 51 may be configured to be inclined so that the angle between the normal V2 and the first direction X is 10° or less.

Figure 11 shows a bait system 60 according to a further modification. As shown in Figure 11, the bait system 60 has a larger diameter bait station 61 and a scoop 62. The bait station 61 has, for example, an inner diameter of 140 mm and a depth of 250 mm. The scoop 62 has a handle 63 and a scooping portion 64, and the normal V3 of the bottom plate 65 of the scooping portion 64 is configured to be more inclined with respect to the first direction X than the scoop 51 according to the above modification.

11(a) and (b), for example, the angle of inclination of the normal V3 of the bottom plate 65 relative to the first direction X is 30°. Specifically, in the embodiment shown in FIG. 11(a), the scoop 62 is inclined toward the X2 side so that the angle K3 between the bottom plate 65 and the back plate 66 is more obtuse. On the other hand, in the embodiment shown in FIG. 11(b), the scoop 62 is inclined toward the X1 side so that the angle K4 between the bottom plate 65 and the back plate 66 is more acute. According to the embodiment shown in FIGS. 11(a) and (b), by inserting the scoop 62 obliquely into the bait station 61, soil G accumulated near the outer periphery of the bottom 61a of the bait station 61 can be easily scooped from the radial center or radial outside.

11(c) and (d), the scoop 62 has an inclination angle of 15° relative to the first direction X of the normal V3 of the bottom plate 65. That is, in the embodiment shown in FIG. 11(c), the scoop 62 is inclined toward the X2 side so that the angle K5 between the bottom plate 65 and the back plate 66 is an obtuse angle. On the other hand, in the embodiment shown in FIG. 11(d), the scoop 62 is inclined toward the X1 side so that the angle K6 between the bottom plate 65 and the back plate 66 is an acute angle. According to the embodiments shown in FIGS. 11(c) and (d), by inserting the scoop 62 obliquely into the bait station 61, soil G accumulated near the center of the bottom 61a of the bait station 61 can be easily scooped from the radial center or radial outer side.

In other words, considering a larger diameter bait station 61 (e.g., an inner diameter of 140 mm, a depth of 250 mm), the scoop 62 may be configured so that the bottom plate 65 is inclined so that the angle between the normal V3 and the first direction X is 30° or less. Furthermore, even with a large diameter bait station 61, considering the need to scoop up soil from the center of the bottom 61a, the scoop 62 may be configured so that the bottom plate 65 is inclined so that the angle between the normal V3 and the first direction X is 15° or less.

In other words, when the scoop 62 is inserted at an angle to the depth direction of the bait station 61, the angle of inclination of the normal V3 of the bottom plate 65 relative to the first direction X may be appropriately set so that the bottom plate 65 is aligned with the bottom 61a of the bait station 61.

The present invention is not limited to the above-described embodiment and various modifications are possible.

In the above embodiment, the scoop is constructed by processing a flat plate into sheet metal, but the scoop may also be constructed using a pipe member. In this case, a curved handle can be constructed by cutting out a long, circumferential portion of the pipe member. Furthermore, a scooping portion, which is continuous with the handle and integrally formed with a back plate and a pair of side plates, can be constructed using the circumferential portion of the pipe member, and a separate member (bottom plate) can be joined to the bottom of this by welding, for example, to construct the scooping portion.

The amount of soil scooped was evaluated using three scoops 7A, 7B, and 7C according to this embodiment for two bait stations 10A and 10B with different inner diameters. Bait station 10A has an inner diameter of 80 mm and a depth of 300 mm. Bait station 10B has an inner diameter of 37 mm and a depth of 300 mm. The normal line V1 of each of the three scoops 7A, 7B, and 7C is parallel to the first direction X, and the width dimension W2 in the Z direction (see Figure 6) is different. Scoop 7A has a width dimension W2 of 38 mm. Scoop 7B has a width dimension W2 of 36 mm. Scoop 7C has a width dimension W2 of 30 mm.

To evaluate the performance, 150 g of soil was placed in bait stations 10A and 10B, and the amount of soil that could be scooped up with shovels 7A, 7B, and 7C was evaluated. The evaluation results are shown in Table 1 below.

As shown in Table 1, shovel 7A could be used with the large-diameter bait station 10A, but could not be inserted into the small-diameter bait station 10B, and was unable to scoop up much soil. Shovel 7B was able to stably scoop up soil from both bait stations 10A and 10B. Because shovel C has a smaller width, the amount it scooped up was slightly less than shovel 7B. Therefore, in this example, of shovels 7A to 7C, shovel 7B was able to stably scoop up soil from both bait stations 10A and 10B.
