[0012] A bait system 1 according to one embodiment of the present invention will be described below with reference to the accompanying drawings. Note that the following description is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0013] Figure 1 is a perspective view showing a bait system 1 according to one embodiment of the present invention. As shown in Figure 1, the bait system 1 has a bait station 10 installed underground, and a lure 4 housed in the bait station 10, or a bait material 5 housed in place of the lure. In Figure 1, a portion of the bait station is shown in a see-through view, and a portion of the lure 4 is shown in a cross-sectional perspective view.

[0014] The bait station 10 is a bottomed cylindrical member having an upper opening 11, a bottom portion 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 portion 12 has a circular bottom opening 12a that penetrates vertically. The outer periphery 13 has a plurality of slits 13a that penetrate radially.

[0015] The bait log 4 is made of wood (such as aspen or red pine) that termites like to eat, and is stored in the bait station 10 to monitor whether or not termites are present in the surrounding area. The bait material 5 contains an agent that eradicates termites. If an inspection of the bait log 4 confirms the presence of termites, the bait log 4 is replaced with the bait material 5 stored in the bait station 10. The bait log 4 and bait material 5 are cylindrical and fit along the inner diameter of the bait station 10.

[0016] Bait station 10 is installed underground so that opening 11 (lid material 14) appears above ground surface S. Bait station 10 also has a cavity 42 formed in the ground below bottom opening 12a. Bait station 10 is configured to allow termites to enter through slits 13a and / or bottom opening 12a to access bait log 4 or bait material 5.

[0017] The bait system 1 of this embodiment further includes a shovel 7 that is used to scrape out soil and / or remove plant roots that have entered the bait station 10 when inspecting the bait logs stored in the bait station 10 and replacing them with bait material.

[0018] Fig. 2 is a perspective view of the shovel 7. As shown in Fig. 2, the shovel 7 has a long handle 20 and a scooping part 30 provided at the lower end (tip) of the handle 20. In this embodiment, the shovel 7 is formed by bending a steel plate (for example, stainless steel may be used for rust prevention) with a thickness of 1 mm and joining a part of the scooping part 30 by welding. Alternatively, the shovel 7 can be formed by various methods such as casting or forging.

[0019] In the following description, with respect 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 respect to the first direction X, the upper side in the drawing is referred to as the X1 side, and the lower side in the drawing is referred to as the X2 side. With respect to the second direction Y, the diagonally downward right side in the drawing is referred to as the Y1 side, and the diagonally upward left side in the drawing is referred to as the Y2 side. With respect to the third direction Z, the diagonally upward right side in the drawing is referred to as the Z1 side, and the diagonally downward left side in the drawing is referred to as the Z2 side.

[0020] Handle 20 has tip 21 at its X1 end (base end). FIG. 3 is a front view of tip 21. As shown in FIG. 3, handle 20 has a width W1 in the Z direction that is substantially constant across the X direction, excluding tip 21. Tip 21 is rounded and tapered so that its width in the Z direction decreases toward the X1 side. The width W1 of handle 20 is set to make it easy for the user to grip, and is 26 mm in this embodiment.

[0021] Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3 and perpendicular to the direction in which the handle 20 extends. As shown in Fig. 4, the handle 20 has an arc-shaped cross section (concave cross section) that is concave toward the Y2 side. By forming 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 or the like can also be held on the Y1 side of the handle 20. Furthermore, by forming 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 the user's grip.

[0022] 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 with the first direction X. The bottom plate 31 is located on the Y1 side of the back plate 32 and the handle portion 20.

[0023] The back plate 32 extends from the Y2-side end of the periphery of the bottom plate 31 toward the X1 side and is connected to the X2-side 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 surface that is concave toward the Y2 side so as to be continuous with the cross-sectional shape of the handle 20.

[0024] The pair of side walls 33 extend toward the X1 side from both edges of the peripheral edge 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.

[0025] 5 is a side view of the scooping unit 30 as viewed from the Z direction. As shown in FIG. 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 extending in the direction 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.

[0026] 6 is a cross-sectional view of the scooping unit 30 taken along line VI-VI in FIG. 5, perpendicular to the first direction X. As shown in FIG. 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 portion. 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 FIG. 6). Furthermore, the bottom plate 31 is formed to be smaller than the bottom opening 12a of the bait station 10.

[0027] Next, a method of using the bait system 1 will be described with reference to Figures 7 to 9. 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 bait logs 4 are placed in the bait station 10, and the opening 11 is closed with the lid member 14. When the bait station installation hole is excavated, a hollow portion 42 having a smaller diameter than the bait station installation hole is also excavated below the bait station installation hole.

[0028] Next, the bait system 1 is left 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 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.

[0029] Next, when the bait lure 4 is removed from the bait station 10 for periodic inspection, the soil G that had accumulated around the bait lure 4 accumulates at the bottom of the bait station 10. As a result, as shown in Figure 7(c), when the bait 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 placement of the bait lure 4 or, in place of the bait lure 4, bait material 5 within the bait station 10.

[0030] In this embodiment, the bait system 1 is provided with a scoop 7, and as shown in Figure 7(d), the scoop 7 can be used to scrape out soil 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 20. Therefore, the handle 20 can be inserted into the bait station 10 with the handle 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 G that has accumulated on the bottom.

[0031] As described 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 through the bottom opening 12a of the bait station 10 in the vertical direction to access the space 42, and the soil G accumulated in the hollow portion 42 can also be scraped out by the scooping unit 30.

[0032] 8(b), edge portion 31a of scooping portion 30 is moved up and down along the inner peripheral wall surface of bait station 10, whereby edge portion 31a can cut roots T of plants extending into bait station 10 through slits 13a at the inner peripheral wall surface of bait station 10. The cut roots T of plants can be scooped up using bottom plate 31 in the same way as soil G and scraped out of bait station 10.

[0033] 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, bait material 5 can be stored in the bait station 10 in place of the bait log 4.

[0034] 9 is a schematic diagram showing the scraping operation of soil G in the bait station 10 using the tip 21 of the handle 20. For example, if the soil G accumulated in the bait station 10 is hard and difficult to scrape out using the scooping part 30 of the shovel 7, the tapered tip 21 can be used to loosen the soil G, as shown in FIG. 9(a).

[0035] Furthermore, as shown in Figure 9(b), if the soil G accumulated in the bait station 10 is wet, the soil G can also be scooped up on the surface Y1 of the handle 20, which has a concave cross section. Therefore, soil loosened using the tip 21 can be scooped up directly with the handle 20. Note that if the soil G is dry and difficult to scoop up with the handle 20, as shown in Figure 9(c), water M may be added to the soil G accumulated in the bait station 10 to moisten the soil G and make it easier to scoop up.

[0036] Furthermore, as shown in FIG. 9(d), the tapered tip 21 may be used to cut roots T of plants and trees extending into the bait station 10.

[0037] The bait system 1 described above has the following advantages.

[0038] (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 extending in a direction perpendicular to the extension direction of the handle portion, it is easy to insert the handle portion 20 into the bait station 10 along the depth direction and use the scooping portion 30 at the X2 side end to scoop up and scrape out deposits of soil, etc. G at the bottom.

[0039] (2) The scooping portion 30 includes a back plate 32 that extends from one of the peripheral edges of the bottom plate 31 in the first direction X and is connected to the tip of the handle portion 20 . As a result, the scooping portion 30 is configured to be L-shaped in a side view by the bottom plate 31 and the back plate 32. Therefore, the deposits scooped by the bottom plate 31 are easily held between the bottom plate 31 and the back plate 32, and spillage from the bottom plate 31 is easily prevented.

[0040] (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 connected to the side edges of the back plate 32, respectively. As a result, a U-shaped portion is formed by the back plate 32 and the pair of side plates 33 at the peripheral edge of the bottom plate 31. Therefore, the U-shaped portion can more easily hold the sediment scooped up by the bottom plate 31, and can more easily prevent it from spilling out from the bottom plate 31.

[0041] (4) In plan view, the bottom plate 31 has an edge portion 31a formed in an arc shape on the edge opposite to the edge portion where the back plate 32 is provided, which protrudes in the opposite direction from the back plate 32. As a result, when the scoop 7 is inserted into the cylindrical hole, the arc-shaped edge portion 31a of the bottom plate 31 can be easily fitted along the inner peripheral surface of the hole, making it easier to scrape off foreign matter (soil, etc. G) adhering to the inner peripheral surface of the bait station 10 or foreign matter (plant roots, etc. T) extending from the inner peripheral surface into the hole. Furthermore, when the radius of curvature R1 of the edge portion 31a is smaller than the inner diameter R0 of the bait station 10, the edge portion 31a can more easily scrape off foreign matter adhering to the inner peripheral surface of the bait station 10.

[0042] (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 easy 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.

[0043] (6) The handle portion 20 is a plate-like member whose cross section perpendicular to the first direction X 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, it is easy to fit the handle portion 20 to the palm of the hand, making it easy to grip.

[0044] (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 accumulated inside the bait station 10, and further to cut roots T of plants and trees extending inside the bait station 10.

[0045] (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.

[0046] (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, and soil G accumulated in the hollow section 42 provided below the bait station 10 can be easily scraped out.

[0047] 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 be configured so that a normal extending in the direction perpendicular to the surface is inclined with respect to the first direction X.

[0048] Figure 10 shows a modified bait system 50. As shown in Figure 10, bait system 50 has the same bait station 10 as the above embodiment, but differs in the configuration of scoop 51. Scoop 51 has handle 52 and scooping part 53, and is configured such that normal V2 of bottom plate 54 of scooping part 53 is inclined with respect to first direction X.

[0049] Specifically, in this modified example, normal V2 of bottom plate 54 is inclined at an angle of 10° with respect to first direction X. According to this modified example, when scoop 51 is inserted with handle 52 inclined with respect to the depth direction of bait station 10, bottom plate 54 of scooping portion 53 can be easily aligned with bottom 12 of bait station 10.

[0050] The inclination direction of the bottom plate 54 may be either a direction approaching the handle 52 (X1 side) or a direction 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.

[0051] According to the embodiment shown in Figure 10(a), when the shovel 51 is inserted with the handle 52 at an angle to the depth direction of the bait station 10, the scooping portion 53 can easily scoop up soil, etc. 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.

[0052] On the other hand, as shown in Figure 10(b), when the shovel 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, etc. G that has accumulated near the outer periphery of the bottom 12 of the bait station 10 from the radial outside to the radial center.

[0053] That is, for a bait station 10 (e.g., inner diameter 80 mm, depth 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.

[0054] Figure 11 shows a bait system 60 according to another 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.

[0055] 11(a) and 11(b), the angle of inclination of the normal V3 of the bottom plate 65 with respect 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 becomes 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 becomes more acute. According to the embodiment shown in FIGS. 11(a) and 11(b), while 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.

[0056] 11(c) and (d), the scoop 62 has an inclination angle of 15° with respect 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), while the scoop 62 is inserted 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.

[0057] That is, considering a larger diameter bait station 61 (e.g., an inner diameter of 140 mm and 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 in the case of 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.

[0058] In other words, when the scoop 62 is inserted at an angle to the depth direction of the bait station 61, the inclination angle 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.

[0059] The present invention is not limited to the above-described embodiment, and various modifications are possible.

[0060] 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 portion can be constructed by cutting out a long, circumferential portion of the pipe member. Furthermore, a scooping portion, which is integrally formed with a back plate and a pair of side plates and is connected to the handle portion, may be constructed using the circumferential portion of the pipe member, and a separate member (bottom plate) may be joined to the bottom of this scooping portion by, for example, welding. [Example]

[0061] 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 three scoops 7A, 7B, and 7C all have normal lines V1 parallel to the first direction X, but have different width dimensions W2 in the Z direction (see Figure 6). 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.

[0062] As an evaluation method, 150 g of soil was placed in bait stations 10A and 10B, and the amount of soil that could be scooped up by shovels 7A, 7B, and 7C was evaluated. The evaluation results are shown in Table 1 below.

[0063] [Table 1]

[0064] 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 could barely scoop up any soil. Shovel 7B was able to stably scoop up soil from both bait stations 10A and 10B. Because shovel C had a smaller width, the amount of soil scooped up was slightly less than that of 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. [Explanation of symbols]
