[0009] Hereinafter, an embodiment of the present invention will be described.

[0010] Embodiment 1 The attachment aid 1A according to the first embodiment of the present invention is a tool used when attaching a plurality of piercing tools 9 to the attachment portion 11 of the clamping attachment structure of the piercing work machine 10 (see FIGS. 5 and 6).

[0011] Here, the piercing tool 9 is a rod-shaped member that is used to pierce the ground 100, such as a lawn, and perform work such as aeration. The piercing tool 9 includes, for example, what is called a tine. A lawn is an area where grass (turfgrass) grows on the ground.

[0012] 10, the piercing work machine 10 is a mechanical device that is coupled to the rear of a traveling vehicle 18, such as a passenger vehicle, to perform piercing work. The piercing work machine 10 pierces multiple piercing tools 9 into the ground 100 to the required depth and frequency. The mounting part 11 is a structural part for mounting a plurality of piercing tools 9. The mounting part 11 is supported by a support frame 12 that can move up and down. Reference numeral 13 in Fig. 10 denotes, for example, a leveling member. The mounting portion 11 in the first embodiment employs a clamping mounting structure.

[0013] Furthermore, the clamping attachment structure is an attachment structure of the type described below. That is, the clamping mounting structure is a type of mounting structure in which, as shown in Figure 11, the mounting portions 95 of multiple piercing tools 9 are inserted in a line between a fixed plate 81 and a clamping plate 82, and then the clamping plate 82 is fastened to the fixed plate 81 with screws 84 such as bolts and screws to clamp (press) the structure.

[0014] The space above becomes a clearance space where the attachment portion 95 of the piercing tool 9 is actually attached. Specifically, the space above becomes an attachment space 83 formed by a first holding portion 86 and a second holding portion 87, which will be described later, facing each other with a gap between them (see FIG. 12(B)).

[0015] The fixed plate 81 is a long, thin, thick metal plate having a predetermined size, and is made of a magnetic metal such as iron. The fixed plate 81 is fixed to, for example, a support plate 85. The fixed plate 81 may be integrated with the support plate 85. Furthermore, the surface of the fixed plate 81 facing the clamping plate 82 is provided with a plurality of first holding portions 86 that clamp and hold the attachment portions 95 of the plurality of piercing tools 9 from one side (see FIG. 12, etc.). The first holding portions 86 are formed, for example, as curved recesses. The number of first holding portions 86 provided is the same as the number of piercing tools 9 to be attached. Furthermore, the fixing plate 81 is provided with screw holes 87 in the portions between the plurality of first holding portions 86, into which the screws 84 are fastened.

[0016] The sandwiching plate 82 is a long, thin, thick metal plate having a predetermined size, and is made of a magnetic metal such as iron. Furthermore, the clamping plate 82 is provided on its surface facing the fixed plate 81 with a plurality of second holding portions 88 that hold the attachment portions 95 of the plurality of piercing tools 9 by clamping them from the opposite side (see FIG. 12, etc.). The second holding portions 88 are formed, for example, as curved recesses. Similar to the first holding portions 86, the second holding portions 88 are provided in the same number as the number of piercing tools 9 to be attached. Furthermore, the clamping plate 82 is provided with screw holes 89 for passing the screws 84 in portions between the plurality of second holding portions 87. A part of the screw holes 89 may be a threaded hole (a hole portion with a female thread formed therein).

[0017] The mounting operation using the clamping mounting structure is generally carried out as follows.

[0018] First, in the sandwich mounting structure, as shown in Figs. 12(B) and 12(C), a sandwiching plate 82 is mounted in advance on a fixed plate 81 with a gap required for mounting. At this time, the clamping plate 82 is temporarily fixed to the fixed plate 81 by loosely tightening the screws 84. At this time, an attachment space 83 is formed between the fixed plate 81 and the clamping plate 82, surrounded by a first holding portion 86 and a second holding portion 87 that face each other with a gap in between. The attachment space 83 is an open space that faces at least downward.

[0019] Next, in the clamping mounting structure, the mounting portions 95 of the multiple piercing tools 9 to be mounted are inserted into the mounting space 83 from below, and the inserted state is maintained. 12(B) and 12(C) show an example in which the attachment portion 95 of the piercing tool 9 is placed in the attachment space 83.

[0020] The reason why the inserted multiple piercing tools 9 are held from below during this work process is that the mounting space 83 is wider than the outer diameter of the mounting part 95, and if they are not held, the multiple piercing tools 9 will fall and the mounting work will not be able to continue, which must be avoided. For example, a bolt screw having a threaded portion 84b consisting of a half-thread with a head 84a is used as the screw 84. The half-thread is a type of screw in which a non-threaded portion 84c where no male thread is formed exists in part of the threaded portion 84b where a male thread is formed (see FIG. 12).

[0021] Next, in the clamping mounting structure, the clamping plate 82 is brought close to the fixed plate 81 by tightening the screws 84, and the mounting portion 95 of the piercing tool 9 is clamped (pressed) within the mounting space 83. As a result, the multiple piercing tools 9 are attached with their attachment portions 95 sandwiched between the fixing plate 81 and the sandwiching plate 82 in the attachment space 83 (see FIG. 11).

[0022] In FIG. 11, two types of piercing tools 9A and 9B are shown as examples of the piercing tool 9. The piercing tool 9 may basically have a structure including a main body 91 for performing the piercing operation and an attachment part 95 used when attaching it to the attachment part 11.

[0023] The piercing tool 9A is a piercing tool having an overall cylindrical structure. The piercing tool 9A has a structure including a main body portion 91A, a tip portion 92A, and an attachment portion 95A. The main body portion 91A is provided with a notched opening 93. The tip portion 92A is open at its tip. The attachment portion 95A has a cylindrical shape, but may also have a solid shape. The piercing tool 9B is a piercing tool having an overall cylindrical structure. The piercing tool 9B has a structure including a main body portion 91B and an attachment portion 95B. The main body portion 91B has a tapered shape on the tip side.

[0024] Incidentally, in the clamping mounting structure, the following procedure is carried out to insert the mounting portions 95 of the multiple piercing tools 9 into the mounting space 83 and hold them in that state.

[0025] That is, the worker holds the multiple piercing tools 9 in one hand and performs the inserting and holding operations, while the same worker tightens the screws 84 with the other hand. This made the work difficult, and the attachment positions of some of the piercing tools 9 sometimes shifted downward. In addition, when the overall spacing between the attachment positions of the plurality of piercing tools 9 is large, it can be difficult to perform the attachment work while holding the tool with one hand. However, in this case, the work may be performed by supporting all of the piercing tools 9 from below with a support means such as a plate member. Figures 11(A) and (B) show examples of support means 200 that may include a human hand.

[0026] (Installation aid) Next, the mounting aid 1A according to the first embodiment will be described.

[0027] As shown in FIGS. 1 to 3, the mounting aid 1A is configured as a structure including a substrate 2 and a magnet 3. The directions indicated by arrows X1, X2, Y1, Y2, Z1, and Z2 in the figure are special directions set based on the mounting aid 1A shown on the paper surface of FIG. 1(A). The arrow X1 indicates the right direction, the arrow X2 indicates the left direction, the arrow Y1 indicates the upward direction, the arrow Y2 indicates the downward direction, the arrow Z1 indicates the forward direction, and the arrow Z2 indicates the backward direction.

[0028] The substrate 2 is a plate member that is elongated in one direction. The substrate 2 is configured as a plate member having a shape longer than the length of the attachment range of the plurality of piercing members 9 attached to the attachment portion 11 of the clip attachment structure.

[0029] The substrate 2 in the first embodiment is a plate member having a predetermined thickness and length and a rectangular planar surface. The substrate 2 is formed from a metal material such as stainless steel. The substrate 2 is preferably a plate member exhibiting non-magnetic physical properties.

[0030] Furthermore, the substrate 2 is provided with a handle 5 so that a user of the mounting aid 1A can hold (grasp) the mounting aid 1A in his / her hand and handle it. The handle portion 5 is not particularly limited in terms of its shape, dimensions, etc. The handle portion 5 in the first embodiment is configured as a part that protrudes from one long side of the substrate 2 and has a shape that forms a rectangular space S between the handle portion 5 and the long side. The handle portion 5 is formed as an extension of the substrate 2.

[0031] The magnet 3 is a magnet placed on one surface 2a of the substrate 2. Reference numeral 2a in Fig. 1(A) indicates one surface of the substrate 2, and reference numeral 2b in Fig. 1(B) indicates the other surface of the substrate 2. As the magnet 3, for example, a permanent magnet is used. The magnet 3 used has a magnetic force strong enough to hold the piercing tool 9 to be attached in the attachment space 83 in the attachment part 11 and temporarily fix it.

[0032] The magnet 3 in the first embodiment is a magnet that is individually placed at positions corresponding (substantially coincident) with the attachment positions of the plurality of piercing tools 9 attached to the attachment part 11. Specifically, a magnet 3A having a ring (annular) shape like a doughnut with a hole in the center is used as the magnet 3 (see FIGS. 1(A), 2(A), and 4).

[0033] In the first embodiment, assuming that the mounting unit 11 is intended to accommodate four piercing tools 9, the smallest unit that can be attached in a row at one time, four magnets 3 (3A) will be arranged. In this assumed case, the ring-shaped magnets 3A are arranged as four magnets 3A1, 3A2, 3A3, and 3A4 (see FIG. 1(A), etc.). In FIGS. 1A, 2A, etc., only magnet 3A1 is shown by a broken line as being a ring-shaped magnet, but the remaining magnets 3A2, 3A3, and 3A4 are also magnets of the same shape.

[0034] As shown in FIG. 4 and other figures, the magnet 3 is disposed in a state where it is housed in a container 4.

[0035] 4 etc., the container 4 is a container (storage case) having a cylindrical storage portion 41 that is open only at the bottom. The container 4 is made of a metal material such as stainless steel. The magnet 3 is housed in the housing portion 41 of the container 4. As a result, the top and side surfaces of the magnet 3 are covered by the container 4, and therefore the top and side surfaces are protected from external factors such as external impacts.

[0036] The container 4 in the first embodiment has a storage section 41 surrounded by an upper surface plate 42 and a side surface plate 43 . The top plate 42 is attached to the upper end of the annular side plate 43 and closes the top of the side plate 43 like a lid. The top plate 42 is supported by a support 44 with screws connected to its underside. A threaded portion 44b is provided on the lower side of the threaded support 44. The support 44 is configured, for example, as a cylindrical member with a half screw. The support 44 is inserted into a mounting hole (not shown) provided at a predetermined position on the substrate 2, with the threaded portion 44b protruding downward from the surface 2b of the substrate 2. A flanged nut 45, for example, is attached to the protruding threaded portion 44b. By tightening the nuts 45, the container 4 is fixed to the substrate 2 with the top plate 42 and the side plate 43 pressed against the substrate 2 via the supports 44.

[0037] The magnet 3 in the first embodiment can be removed together with the container 4. This allows the magnet 3 to be replaced with a new one or with a magnet having a different magnetic force.

[0038] Next, a method of using the mounting aid 1A will be described.

[0039] First, when using the mounting aid 1A, the following prerequisites are required: That is, the piercing tool 9 to be attached must have magnetic properties at least in the attachment portion 95. The piercing tool 9 may also be magnetic in its entirety. Although not an essential prerequisite, it is preferable that one or both of the fixed plate 81 and the sandwiching plate 82 in the mounting portion 11 having the sandwiching mounting structure have magnetic properties.

[0040] The attachment aid 1A is installed with the magnet 3 facing between the fixing plate 81 and the clamping plate 82 of the attachment part 11 having a clamping attachment structure when the attachment parts 95A, 95B of the multiple (four in this example) piercing tools 9 (9A, 9A, 9B, 9B) are inserted between them (FIG. 5). The space between them at this time becomes the attachment space 83 described above.

[0041] In the first embodiment, as shown in FIG. 12, the attachment aid 1A is installed on the upper surfaces of the fixing plate 81 and the sandwiching plate . At this time, the mounting aid 1A is installed in a state where the four magnets 3 (3A) directly face the four mounting spaces 83. Also, since the fixing plate 81 and the clamping plate 82 are plate members made of a magnetic metal material such as iron, the mounting aid 1A is firmly fixed to the upper surfaces of the fixing plate 81 and the clamping plate 82 by the magnetic attraction force generated by the magnet 3 (3A).

[0042] Then, the installation worker holds the four piercing tools 9 (9A, 9A, 9B, 9B) to be installed in his / her hands and inserts each of the installation portions 95A, 95B into the four installation spaces 83 in the mounting portion 11, respectively.

[0043] When the four piercing tools 9 (9A, 9A, 9B, 9B) are inserted by their respective mounting portions 95A, 95B into the respective mounting spaces 83, they are held within the respective mounting spaces 83 by the magnetic attraction of the respective magnets 3 of the mounting aid 1A. In reality, the piercing tool 9 is held with each mounting portion 95A, 95B attached to each magnet 3 of the mounting aid 1A, or attached to either the fixed plate 81 or the clamping plate 82 in the mounting space 83 which receives the magnetic force of the magnet 3. Therefore, the four piercing tools 9 (9A, 9A, 9B, 9B) inserted into the respective mounting spaces 83 will not fall even if the mounting worker lets go of them.

[0044] In this state, the installation worker tightens the screws 84 to bring the clamping plate 82 close to the fixing plate 81. As a result, the four piercing tools 9 (9A, 9A, 9B, 9B) are attached with their respective attachment portions 95A, 95B sandwiched (pressed) between the fixed plate 81 and the clamping plate 82 within the attachment space 83 (see Figure 6).

[0045] The attachment aid 1A is removed from the attachment part 11 after the attachment work of the four piercing tools 9 is completed. At this time, the completion of the attachment work refers to the stage at which it has been confirmed that the tightening work of the screw 84 has been completed and the attachment of the piercing tool 9 has been completed, for example.

[0046] As described above, when the attachment aid 1A is used to attach multiple piercing tools 9 to the mounting portion 11 having a clamping attachment structure, the attachment work can be performed without the attachment worker having to support the multiple piercing tools 6 with their hands or the like.

[0047] Variant. The mounting aid of the present invention is not limited to the configuration example shown in embodiment 1. The mounting aid of the present invention can be modified as appropriate without departing from the technical scope of the invention. The present invention also includes, for example, the following modifications.

[0048] FIG. 7 shows a mounting aid 1B of the first modified example. Mounting aid 1B of variant 1 is an example of a configuration that allows for changing the position of magnet 3. Mounting aid 1B has a slot 6 in substrate 2 for placing magnet 3, and is structured so that the position of magnet 3 can be adjusted within the movable range of slot 6. The elongated hole 6 is a hole that is long along the longitudinal direction of the substrate 2. The position where the magnet 3 is arranged can be changed by loosening the nut 45 of the container 4. 7 is provided to individually accommodate each of the plurality of magnets 3, but a single slot 60 may also be provided as an example slot shown at the bottom of Fig. 7(A) that is shared by the plurality of magnets 3. In the case of this slot 60, the degree of freedom in changing the arrangement positions of the plurality of magnets 3 is increased.

[0049] FIG. 8 shows a mounting aid 1C of the second modification. The mounting aid 1C of the modified example 2 is a configuration example in which the handle portion 5 in the mounting aid 1A according to the embodiment 1 is omitted. Moreover, the mounting aid 1C employs a configuration in which the magnet 3 is housed in a container 4, and the container 4 is then adhered and fixed to one surface 2a of the substrate 2.

[0050] FIG. 9 shows an attachment aid 1D of the third modification. Mounting aid 1D of modified example 3 is a configuration example in which long, plate-shaped magnet 3B is arranged as magnet 3 along the longitudinal direction of substrate 2. Similar to magnet 3A in embodiment 1, plate-shaped magnet 3B is placed on substrate 2 while housed in container 4. Furthermore, plate-shaped magnet 3B may be arranged by being glued to substrate 2, or alternatively, similar to embodiment 1, it may be arranged so that container 4 is attached using support 42 and nut 45.

[0051] In addition, the attachment aid of the present invention is more effective and useful when used when attaching three or more piercing tools 9. In this case, it is advisable to make adjustments such as changing the shape of the substrate 2 to a longer shape or increasing the number of magnets 3. Furthermore, the installation location of the attachment aid is not particularly limited as long as it can be held (temporarily fastened) by the magnetic force of the multiple piercing tools. Another example of the installation location is to install it on the clamping plate 82 of the attachment part.

[0052] The attachment aid of the present invention, apart from the first aspect described above, can be briefly summarized as follows:

[0053] A second aspect of the present invention is an attachment aid according to the first aspect, wherein the magnets are individually arranged at positions corresponding to the attachment positions of the piercing tools. According to the second aspect, the magnetic force of the magnet can be exerted on each of the plurality of piercing tools without waste.
