Abstract
Description
[Technical Field]
[0001] The present invention relates to a handle-equipped tool assembly sheet that can be assembled into a handle-equipped tool. [Background technology]
[0002] As an example of the above-mentioned handled tool assembly sheet, a paper material that can be assembled into a measuring paper spoon, which is a type of handled tool, as disclosed in Patent Document 1, is known.
[0003] The stock is a single sheet and is configured so that a measuring container can be formed by a bottom wall, a front wall, a rear wall, and a pair of side walls, and a gripper top wall and a gripper side wall can form a gripper. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 4-120332 Summary of the Invention [Problem to be solved by the invention]
[0005] However, in the above-mentioned conventional paper stock, when a load is applied to the measuring box while holding the handle in an assembled state, the measuring box may move around the boundary with the handle, which may lead to a loss of comfort in use.
[0006] In view of the above, an object of the present invention is to provide a handle tool assembly sheet that allows for the assembly of handle tools that are comfortable to use. [Means for solving the problem]
[0007] The handle-equipped tool assembling sheet of the present invention is A handle-attached tool assembling sheet for assembling a handle-attached tool having a handle to be used as a handle, a holder forming portion that forms a holder that holds a tangible object; a handle forming portion that forms a handle extending rearward in the front-rear direction from the holding portion; a reinforcing portion extending rearward from the rear end of the holding portion and forming a reinforcing portion that can abut against the back surface of the handle, The retaining portion forming portion is a bottom forming portion that forms the bottom of the holding portion; a pair of side wall forming portions that form side walls of the holding portion; a rear wall forming portion that forms a rear wall of the holding portion, each of the pair of side wall forming portions is bendably connected to a different side edge of the bottom forming portion; the rear wall forming portion is bendably connected to the rear side of the bottom forming portion, the handle forming portion has a handle extension portion that is bendable relative to a rear side of the rear wall forming portion and extends from the rear wall forming portion, The reinforcing portion is The bottom forming portion is adjacent to the rear wall forming portion and the side wall forming portion and is configured to be bendable relative to the rear wall forming portion, and a bendable fold line is formed extending from the intersection of the rear edge of the bottom forming portion and the side edge of the rear wall forming portion in a direction outward in the width direction and toward the rear in the fore-and-aft direction.
[0008] When the handle tool assembly sheet of the above configuration is assembled to the handle tool, the reinforcing part formed by the reinforcing forming part is configured to extend rearward from the rear end of the holding part and abut against the back surface of the handle, so that even if a load is applied to the holding part while holding the handle in use, the reinforcing part functions like a diagonal brace between the holding part and the back surface of the handle, thereby preventing the holding part from moving around the boundary with the handle as a base point.
[0009] Therefore, the handle tool assembling sheet allows the user to assemble a handle tool that is comfortable to use.
[0010] In the handle-equipped tool assembling sheet of the present invention, A pair of the reinforcing formation portions is provided, a first reinforcing formation portion that is the reinforcing formation portion located on one side in a left-right direction perpendicular to the front-rear direction; a second reinforcing formation portion that is the reinforcing formation portion located on the other side in the left-right direction perpendicular to the front-rear direction, The tip end of the fold line of the first reinforcing formation portion and the tip end of the fold line of the second reinforcing formation portion are arranged symmetrically in the left-right direction. This may be done.
[0011] In this way, the reinforcing portion formed by the first reinforcing forming portion and the reinforcing portion formed by the second reinforcing forming portion can be easily abutted against the back surface of the handle while being arranged symmetrically on the left and right.Therefore, when a load is applied to the holding portion while holding the handle and using it, the reinforcing portion formed by the first reinforcing forming portion and the reinforcing portion formed by the second reinforcing forming portion can support the holding portion in a balanced manner in the left and right directions relative to the handle, thereby preventing the holding portion from tilting or the handle from twisting.
[0012] In the handle-equipped tool assembling sheet of the present invention, The handle forming portion has a pair of handle folding portions that are bendably connected to the side edges of the handle extending portion, One of the pair of handle folding portions can be folded so as to overlap the first reinforcing portion on an outward side, The other of the pair of handle folding portions can be folded so as to overlap the second reinforcing portion on the outward side. This may be done.
[0013] In this way, one of the handle folding portions prevents the position of the reinforcement portion formed by the first reinforcement forming portion from shifting outward, and the other handle folding portion prevents the position of the reinforcement portion formed by the second reinforcement forming portion from shifting outward.Therefore, when a load is applied to the holding portion while holding the handle and using it, it becomes easier to maintain a state in which the reinforcement portion formed by the first reinforcement forming portion and the reinforcement portion formed by the second reinforcement forming portion support the holding portion in a balanced manner in the left-right direction relative to the handle.
[0014] The handle-equipped tool assembling sheet of the present invention is One of the pair of handle folding portions is foldably connected to the first reinforcing portion, The other of the pair of handle folding portions is bendably connected to the second reinforcing portion. This may be done.
[0015] In this way, the reinforcing portion formed by the first reinforcing portion and the reinforcing portion formed by the second reinforcing portion are connected to the handle, so that the reinforcing portion formed by the first reinforcing portion and the reinforcing portion formed by the second reinforcing portion are less likely to move relative to the handle, which makes it less likely that the holding portion will move relative to the handle.
[0016] In the handle-equipped tool assembling sheet of the present invention, A retaining portion may be extended from one of the pair of folding handle portions to directly or indirectly retain the other of the pair of folding handle portions.
[0017] This makes it easier to maintain the pair of handle folding portions in the folded state, and therefore makes it easier to maintain the shape of the assembled handle. [Effects of the Invention]
[0018] As described above, the handle tool assembling sheet of the present invention can provide the excellent effect of enabling the assembly of a handle tool that is comfortable to use. [Brief explanation of the drawings]

[0061] When the right handle side extension 321 is inserted between the left reinforcing side extension 320 and the left handle side fold-in portion 311, the left handle side extension 321 holds the left handle fold-in portion 31 against the other handle fold-in portion 31. In this way, the right handle side extension 321 constitutes a holding portion that indirectly holds one handle fold-in portion 31 against the other handle fold-in portion 31.
[0062] When the left handle side extension portion 321 is inserted between the right handle side extension portion 321, which is inserted between the left reinforcing side extension portion 320 and the left handle side fold-in portion 311, and the left rear connecting portion 312, the right handle fold-in portion 31 is held against the left handle fold-in portion 31. In this way, the left handle side extension portion 321 constitutes a holding portion that indirectly holds the right handle fold-in portion 31 against the left handle fold-in portion 31.
[0063] That is, the pair of rear continuous portions 312 in this embodiment each constitutes a separate retaining portion.
[0064] The above is the configuration of the assembly sheet 1 according to this embodiment. Next, a method for assembling the assembly sheet 1 into a handle-equipped tool will be described.
[0065] Fig. 1 shows the assembly sheet 1 as seen from one side where the score processing is performed, while Figs. 6, 7, 8, 9(a), and 9(b) show the assembly sheet 1 as seen from the other side. Furthermore, in the explanation of the method of assembling the assembly sheet 1 into a handle-attached tool, the "left side" refers to the left side of the center line CL when the assembly sheet 1 is seen from one side, and the "right side" refers to the right side of the center line CL when the assembly sheet 1 is seen from one side.
[0066] The assembly sheet 1 of this embodiment is assembled into a handle tool by forming the holding portion forming portion 2 into the holding portion and the handle forming portion 3 into the handle, and after forming the holding portion forming portion 2 into the holding portion, a reinforcing portion is formed by the reinforcing forming portion 4 when the handle forming portion 3 is formed into the handle.
[0067] To form the holding portion, the front wall forming portion 23, the rear wall forming portion 22, and the pair of side wall forming portions 21 are raised relative to the bottom forming portion 20 (see FIGS. 2 and 3).
[0068] At this time, when the shape-retaining connecting portion 241 is folded in half along the folding line 2410 and the front edge 210 of the left side wall forming portion 21 is positioned near the left edge 230 of the front wall forming portion 23 and the front edge 210 of the right side wall forming portion 21 is positioned near the right edge 230 of the front wall forming portion 23, the front edges of the pair of side wall forming portions 21 are moved inward. Therefore, the pair of side wall forming portions 21 are curved so as to bulge outward.
[0069] Next, the shape-retaining connecting portion 241, which is folded in half, is bent inward and moved forward of the outer surface of the front wall forming portion 23 (see FIG. 4). Furthermore, the base-side extending portion 2400 is bent at the boundary between the front wall forming portion 23 and the base-side extending portion 2400, so that the front wall forming portion 23 overlaps the shape-retaining connecting portion 241 on the front side, and further, the tip-side extending portion 2401 is inserted between the shape-retaining connecting portion 241 and the front wall forming portion 23 (see FIGS. 5(a) and 5(b)).
[0070] The tip-side extension portion 2401 can be bent at the portion closer to the tip than the curved fold line 2402 toward the portion closer to the base end than the curved fold line 2402, making it easier to insert the portion closer to the tip than the curved fold line 2402 between the shape-retaining connecting portion 241 and the front wall forming portion 23.
[0071] In this way, the front wall forming portion 23, the rear wall forming portion 22, and the pair of side wall forming portions 21 are maintained in a raised state relative to the bottom forming portion 20, and a holding portion T1 is formed.
[0072] Furthermore, since the shape-retaining connecting portion 241 is arranged with the base extension portion 2400 overlapping on the forward side, the state in which it is folded in half along the fold line is maintained, and thereby the pair of side wall forming portions 21 are also maintained in a curved state in which they bulge outward.
[0073] Next, the reinforcing portion 4 is folded in half along the folding line 42 to form the reinforcing portion T3 (see FIG. 6).
[0074] To form the handle, the handle extension 30 is folded at the boundary between the handle extension 30 and the rear wall forming portion 22 (at the rear edge 220 of the rear wall forming portion 22) relative to the rear wall forming portion 22. At this time, the reinforcement-side folded portion 310 is folded inward and overlaps the handle-side folded portion 311 (see FIG. 7).
[0075] Furthermore, by folding the handle side folded portion 311 at the boundary between the left handle side folded portion 311 and the left side of the handle extension portion 30 (at the position of the left side edge 300 of the handle extension portion 30), the handle side folded portion 311 is raised relative to the handle extension portion 30.
[0076] In this way, the rear ends of the reinforcing portions T3 formed by the pair of reinforcing forming portions 4 approach each other and come into contact with the handle extension portion 30 (see FIG. 8). At this time, since the right reinforcing side extension 320 is folded at the boundary with the right reinforcing side fold-in portion 310, the fold at the boundary between the right reinforcing side extension 320 and the right reinforcing side fold-in portion 310 stands upright against the back surface of the handle, and this fold acts as a pillar supporting the right handle side fold-in portion 311 folded against the handle extension portion 30.
[0077] Then, the left reinforcement side extension portion 320 is arranged overlapping the left handle side fold portion 311 on the inward side, and the right reinforcement side extension portion 320 is folded toward the right reinforcement side fold portion 310 at the boundary with the right reinforcement side fold portion 310, and is arranged between the left reinforcement forming portion 4 and the left reinforcement side fold portion 310.
[0078] Furthermore, the right handle side extension portion 321 is inserted between the left reinforcing side extension portion 320 and the left handle side fold-in portion 311, and the left handle side extension portion 321 is inserted between the right handle side extension portion 321 and the right rear connecting portion 312.
[0079] In this way, the handle T2 is formed and the shape of the handle T2 is maintained (see Fig. 9(a) and Fig. 9(b)). In this way, the assembly sheet 1 is assembled into the handled tool T (see Fig. 10(a)).
[0080] In the handled tool T, the reinforcing part T3 extending rearward from the rearward corner of the holding part T1 abuts against the back surface of the handle part T2 (the back surface of the top surface of the handle T2), and the reinforcing part T3 functions like a diagonal brace between the holding part T1 and the handle T2 (see FIG. 10(b)). Therefore, even if a load is applied to the holding part T1 when the user is scooping up a tangible object with the holding part T1 while grasping the handle T2 or when the holding part T1 is receiving a tangible object, the boundary between the holding part T1 and the handle T2 is less likely to bend.
[0081] This prevents the handle tool T from being uncomfortable to use due to the holding part T1 moving relative to the handle T2. In addition, because the handle T2 itself is less likely to bend, it is also possible to prevent the handle tool T from being uncomfortable to use due to the holding part T1 moving as the handle T2 bends.
[0082] As described above, according to the assembly sheet 1 of this embodiment, when it is assembled to the handled tool T, the reinforcing part T3 formed by the reinforcing forming part 4 is configured to extend rearward from the rear end of the holding part T1 and abut against the back surface of the handle T2, so that even if a load is applied to the holding part T1 while holding the handle T2 in use, the reinforcing part T3 functions like a diagonal brace between the holding part T1 and the back surface of the handle T2, thereby preventing the holding part T1 from moving around the boundary with the handle T2 as a base point.
[0083] Therefore, the assembly sheet 1 of this embodiment allows the user to assemble the handled tool T in a comfortable manner.
[0084] Furthermore, in the assembly sheet 1 of the present invention, the tip of the fold line 42 of the left reinforcing formation portion 4 and the tip of the fold line 42 of the right reinforcing formation portion 4 are arranged symmetrically in the width direction, so that the reinforcing portion T3 formed by the left reinforcing formation portion 4 and the reinforcing portion T3 formed by the right reinforcing formation portion 4 can be easily abutted against the back surface of the handle when they are arranged symmetrically on the left and right sides. Therefore, when a load is applied to the holding portion T1 while holding the handle T2 in use, the reinforcing portion T3 formed by the left reinforcing formation portion 4 and the reinforcing portion T3 formed by the right reinforcing formation portion 4 can support the holding portion T1 in a balanced manner in the width direction relative to the handle T2, thereby preventing the holding portion T1 from tilting or the handle T2 from twisting.
[0085] Furthermore, in the assembly sheet 1 of this embodiment, the folding portion 31 for the left handle can be bent so that it overlaps the left reinforcing forming portion 4 on the outward side, and the folding portion 31 for the right handle can be bent so that it overlaps the right reinforcing forming portion 4 on the outward side. Therefore, the folding portion 31 for the left handle prevents the position of the reinforcing portion T3 formed by the left reinforcing forming portion 4 from shifting outward, and the folding portion 31 for the right handle prevents the position of the reinforcing portion T3 formed by the right reinforcing forming portion 4 from shifting outward. Therefore, when a load is applied to the holding portion T1 while the handle T2 is being held and used, the reinforcing portion T3 formed by the left reinforcing forming portion 4 and the reinforcing portion T3 formed by the right reinforcing forming portion 4 can easily maintain a state in which they support the holding portion T1 in a balanced manner in the width direction relative to the handle T2.
[0086] Furthermore, in the assembled sheet 1 of this embodiment, the reinforcing portion T3 formed by the left reinforcing portion 4 and the reinforcing portion T3 formed by the right reinforcing portion 4 are connected to the pattern T2 (side surface of the pattern T2), so the reinforcing portion T3 formed by the left reinforcing portion 4 and the reinforcing portion T3 formed by the right reinforcing portion 4 are less likely to move relative to the pattern T2. This makes it less likely that the holding portion T1 will move relative to the pattern T2.
[0087] Furthermore, since the left-handle fold-in portion 31 is foldably connected to the left reinforcing formation portion 4 and the right-handle fold-in portion 31 is foldably connected to the right reinforcing formation portion 4, the left reinforcing formation portion 4 is more easily positioned in a fixed location because the left reinforcing formation portion 4 and the left-handle fold-in portion 31 are foldably connected, and the right reinforcing formation portion 4 is more easily positioned in a fixed location because the right reinforcing formation portion 4 and the right-handle fold-in portion 31 are foldably connected. Therefore, when a load is applied to the holding portion T1 while holding the handle T2, the reinforcing portion T3 formed by the left reinforcing formation portion 4 and the reinforcing portion T3 formed by the right reinforcing formation portion 4 more easily maintain a state in which they support the holding portion T1 in a balanced manner in the width direction relative to the handle T2.
[0088] Furthermore, in the assembly sheet 1 of this embodiment, a valley is formed by folding the right handle side extension portion 320 relative to the left reinforcing side fold portion 310, and a pair of reinforcing portions T3 can be placed in this valley, making it easier to maintain the positions of the tip ends of the pair of reinforcing portions T3 aligned.
[0089] Furthermore, the assembly sheet 1 of this embodiment is configured so that the left-handle folding portion 31 can be held to the right-handle folding portion 31 by the retaining portion formed by the right-handle side extension portion 321, and so that the right-handle folding portion 31 can be held to the left-handle folding portion 31 by the retaining portion formed by the left-handle side extension portion 321, making it easier to maintain the folded state of the pair of handle folding portions 31 and easier to maintain the shape of the assembled handle T2.
[0090] Furthermore, the handle extension 30 of the assembly sheet 1 of this embodiment has multiple bending lines 301 extending radially from the center, which prevents random creases from occurring around the positions where the tip ends of the pair of reinforcing parts T3 abut, thereby making it less likely that the aesthetic appearance will be impaired.
[0091] Hereinafter, a sheet for assembling a handled tool (hereinafter referred to as an assembly sheet) according to a second embodiment of the present invention will be described with reference to the accompanying drawings.
[0092] The assembly sheet according to this embodiment is also configured so that it can be assembled into a scooping tool, which is a type of handled tool having a handle that serves as a handle.
[0093] For convenience, the names of the components and the symbols attached to the names of the components described in the description of the assembly sheet of this embodiment include the same components as those described in the assembly sheet of the first embodiment above.
[0094] As shown in FIG. 11, the assembly sheet 1 includes a holding portion forming portion 2 that forms a holding portion that holds a tangible object, a handle forming portion 3 that forms a handle that extends rearward from the holding portion, and a pair of reinforcing portions 4 that extend rearward from the rear end of the holding portion and form reinforcing portions that can abut against the back surface of the handle.
[0095] As shown in Figures 17(a) and 17(b), the handle attachment T comprises a holding portion T1, a handle T2 extending rearward from the holding portion T1, and a reinforcing portion T3 extending rearward from the holding portion T1 and abutting the back surface of the handle T2.
[0096] In the following description, the direction in which the holding portion forming portion 2 and the handle forming portion 3 are aligned (the direction corresponding to the top and bottom in Figure 11) is referred to as the front-to-back direction, the direction from the handle forming portion 3 side toward the holding portion forming portion 2 side (the direction toward the top in Figure 11) is referred to as the front direction, and the direction opposite to the front direction (the direction toward the bottom in Figure 11) is referred to as the rear direction.
[0097] In addition, the direction perpendicular to the front-to-rear direction (the direction corresponding to the left-to-right direction in Figure 11) is referred to as the width direction, the direction toward the center line CL in the width direction is referred to as the inward direction, and the direction away from the center line CL in the width direction is referred to as the outward direction.
[0098] The tangible object received by the holder formed by the holder forming portion 2 is, for example, a powdery or granular fluid, a solid, or the like.
[0099] As shown in Figure 11, the retaining portion forming portion 2 of this embodiment has a bottom forming portion 20 that forms the bottom of the retaining portion, a pair of side wall forming portions 21 that form the side walls of the retaining portion, a rear wall forming portion 22 that forms the rear wall of the retaining portion, a front wall forming portion 23 that forms the front wall of the retaining portion, and a retaining side shape-retaining structure 24 for maintaining the shape of the assembled retaining portion.
[0100] The bottom forming portion 20 is rectangular.
[0101] The bottom forming portion 20 has a front edge 200 located on the front side in the front-to-rear direction, a rear edge 201 aligned with the front edge 200 in the front-to-rear direction, and a pair of side edges 202 aligned in the width direction. Hereinafter, the side edge 202 illustrated on the left side in Fig. 11 will be referred to as the left side edge 202, and the side edge 202 illustrated on the right side in Fig. 11 will be referred to as the right side edge 202.
[0102] The front side 200 and the rear side 201 are parallel to each other, and the left side 202 and the right side 202 are parallel to each other.
[0103] The pair of side wall forming portions 21 are rectangular. Each of the pair of side wall forming portions 21 has a front edge 210 extending straight outward from the front edge 200 (the end of the front edge 200) of the bottom forming portion 20, a rear edge 211 extending straight outward from the rear edge 201 (the end of the rear edge 201) of the bottom forming portion 20, an inner edge that is the same part as either the left edge 202 or the right edge of the bottom forming portion 20, and an outer edge 212 that is aligned with the inner edge in the width direction and that forms part of the outline of the assembled sheet 1.
[0104] The front edge 210 and the rear edge 211 are aligned in the front-to-rear direction. The inner edge of the side wall forming portion 21 shown on the left side in Fig. 11 is the same part as the left edge 202 of the bottom forming portion 20, and the inner edge of the side wall forming portion 21 shown on the right side in Fig. 11 is the same part as the right edge 202 of the bottom forming portion 20. The pair of side wall forming portions 21 in this embodiment have symmetrical shapes with respect to the center line CL.
[0105] The rear wall forming portion 22 is rectangular. The rear wall forming portion 22 has a front side that is the same as the rear side 200 of the bottom forming portion 20, a rear side 220 that is aligned with the front side in the front-to-rear direction, and a pair of side sides 221 that are aligned in the width direction. Hereinafter, the side side 221 illustrated on the left side in FIG. 11 will be referred to as the left side 221, and the side side 221 illustrated on the right side in FIG. 11 will be referred to as the right side 221.
[0106] The front and rear edges 220 are parallel to each other. The left edge 221 extends rearward from the rear end of the left edge 202 of the bottom forming portion 20, and the right edge 221 extends rearward from the rear end of the right edge 202 of the bottom forming portion 20. The left edges 221 and 221 are also parallel to each other.
[0107] The front wall forming portion 23 is rectangular. The front wall forming portion 23 has a front edge 230 located on the front side, a rear edge that is aligned with the front edge 230 in the front direction and is the same part as the front edge 200 of the bottom forming portion 20, and a pair of side edges 231 that are aligned in the width direction. Hereinafter, the side edge 231 illustrated on the left side in FIG. 11 will be referred to as the left side edge 231, and the side edge 231 illustrated on the right side in FIG. 11 will be referred to as the right side edge 231.
[0108] The front edge 230 and the rear edge are parallel to each other. The left edge 231 extends forward from the front end of the left edge 202 of the bottom forming portion 20, and the right edge 231 extends forward from the front end of the right edge 202 of the bottom forming portion 20. The left edge 231 and the right edge 231 are also parallel to each other.
[0109] The holding side shape-retaining structure 24 has a shape-retaining extension portion 240 extending forward from the front wall forming portion 23 and a pair of shape-retaining connecting portions 241 connected to the front edge 210 of the side wall forming portion 21.
[0110] The shape-retaining extension portion 240 has a base-side extension portion 2400 that extends forward from the front edge of the front wall forming portion 23, and a tip-side extension portion 2401 that extends forward from the base-side extension portion 2400.
[0111] The base-side extending portion 2400 is rectangular and has a front side and a rear side that are aligned in the front-rear direction and parallel to each other, and a pair of side sides that are aligned in the width direction.
[0112] The rear side of the base side extending portion 2400 is the same part as the front side 230 of the front wall forming portion 23. A cut line 2402 is formed on the rear side of the base side extending portion 2400, penetrating across both sides.
[0113] The tip extension 2401 is a claw that can be inserted into the cut line 2402 .
[0114] 11 is adjacent to the left side 231 of the front wall forming portion 23 in the width direction, but is discontinuous with the left side 231 of the front wall forming portion 23. Therefore, the left side shape-retaining connecting portion 241 is configured to be able to move independently of the front wall forming portion 23.
[0115] 11 is adjacent to the right side 231 of the front wall forming portion 23 in the width direction, but is discontinuous with the right side 231 of the front wall forming portion 23. Therefore, the right side shape-retaining connecting portion 241 is also configured to be able to move independently of the front wall forming portion 23.
[0116] Here, the reinforcement forming portion 4 will be described. One of the pair of reinforcement forming portions 4 (the reinforcement forming portion 4 located on the left side in FIG. 11) is a first reinforcement forming portion 4, which will be referred to hereinafter as the left reinforcement forming portion 4. The other of the pair of reinforcement forming portions 4 (the reinforcement forming portion 4 located on the right side in FIG. 11) is a second reinforcement forming portion 4, which will be referred to hereinafter as the right reinforcement forming portion 4.
[0117] The reinforcing forming portion 4 has a front edge which is the same as the rear edge 211 of the side wall forming portion 21, a rear edge 40 which is aligned with the front edge in the front-to-rear direction, an inner edge which is the same as the side edge 221 of the rear wall forming portion 22, and an outer edge 41 which is aligned with the inner edge in the width direction and which forms part of the outline of the assembled sheet 1.
[0118] The left reinforcement forming portion 4 has a fold line 42 formed along a straight line connecting the intersection of the rear edge 201 of the bottom forming portion 20 and the left edge 221 of the rear wall forming portion 22 and the intersection of the rear edge of the left reinforcement forming portion 4 itself and the outer edge 41. Therefore, this fold line 42 extends outward and rearward from the intersection of the rear edge 201 of the bottom forming portion 20 and the left edge 221 of the rear wall forming portion 22.
[0119] The right reinforcement forming portion 4 has a fold line 42 formed along a straight line connecting the intersection of the rear edge 201 of the bottom forming portion 20 and the right edge 221 of the rear wall forming portion 22 and the intersection of the rear edge of the right reinforcement forming portion 4 itself and the outer edge 41. Therefore, this fold line 42 extends outward and rearward from the intersection of the rear edge 201 of the bottom forming portion 20 and the right edge 221 of the rear wall forming portion 22.
[0120] The handle forming portion 3 has a handle extension portion 30 extending rearward from the rear edge 220 of the rear wall forming portion 22, a pair of handle folding portions 31 connected adjacent to the handle extension portion 30 on the outward side, and a handle side shape retention structure 32 for maintaining the shape of the assembled handle.
[0121] The handle extension 30 has a front side that is formed of the same part as the rear side 220 of the rear wall forming portion 22, and a pair of side sides 300 that extend rearward from different ends of the front side. Hereinafter, the side side 300 shown on the left side in Fig. 11 will be referred to as the left side 300, and the side side 300 shown on the right side in Fig. 11 will be referred to as the right side 300.
[0122] The left side 300 and the right side 300 are configured to approach each other as they move toward the rear.
[0123] Each of the pair of handle folding portions 31 has a pair of reinforcing side folding portions 310 connected to the rear side of the reinforcing forming portion 4, and a pair of handle side folding portions 311 connected to the handle extension portion 30 and the reinforcing side folding portions 310.
[0124] The reinforcing-side folded portion 310 is connected to the rear side 40 of the reinforcing portion 4.
[0125] In the following description, the handle folding portion 31, the reinforcing-side folding portion 310, the handle side folding portion 311, and the rear connecting portion 312 located to the left of the center line CL in Figure 11 will be referred to as the left handle folding portion 31, the left reinforcing-side folding portion 310, the left handle side folding portion 311, and the left rear connecting portion 312. In addition, the handle folding portion 31, the reinforcing-side folding portion 310, the handle side folding portion 311, and the rear connecting portion 312 located to the right of the center line CL in Figure 11 will be referred to as the right handle folding portion 31, the right reinforcing-side folding portion 310, the right handle side folding portion 311, and the right rear connecting portion 312.
[0126] The left handle side fold portion 311 is connected to the left side edge 300 of the handle extension portion 30 and the left reinforcement side fold portion 310, and is configured to be bendable at the boundary between the left handle side fold portion 311 and the left reinforcement side fold portion 310. The right handle side fold portion 311 is connected to the right side edge 300 of the handle extension portion 30 and the right reinforcement side fold portion 310, and is configured to be bendable at the boundary between the right handle side fold portion 311 and the right reinforcement side fold portion 310.
[0127] The handle side shape retention structure 32 has a reinforcement side extension portion 320 that extends to the right reinforcement side fold portion 310, and a cut line 321 that is formed to penetrate both sides of the left handle side fold portion 311, and into which the reinforcement side extension portion 320 can be inserted.
[0128] The reinforcement-side extending portion 320 has a base-side extending portion 3200 adjacent to the reinforcement-side folded portion 310 on the outward side, and an extending claw portion 3201 extending outward from the base-side extending portion 3200.
[0129] The base side extension portion 3200 is configured to be placed on top of one side of the left handle side folding portion 311 facing outward, with the pair of handle folding portions 31 folded relative to the handle extension portion 30.
[0130] The extended claw portion 3201 is configured so as to be insertable into the cut line 3200 when the pair of handle folding portions 31 are bent relative to the handle extending portion 30 and the base side extending portion 3200 is bent relative to the handle extending portion 30.
[0131] When the extended claw portion 3201 is inserted into the cut line 3200, the left-handle folding portion 31 is held against the right-handle folding portion 31 by the reinforcing-side extended portion 320. In this way, the reinforcing-side extended portion 320 constitutes a holding portion that holds the left-handle folding portion 31 against the right-handle folding portion 31.
[0132] The above is the configuration of the assembly sheet 1 according to this embodiment. Next, a method for assembling the assembly sheet 1 into a handle-equipped tool will be described.
[0133] The assembly sheet 1 of this embodiment is assembled into a handle tool by forming the holding portion forming portion 2 into the holding portion and the handle forming portion 3 into the handle, and after forming the holding portion forming portion 2 into the holding portion, a reinforcing portion is formed by the reinforcing forming portion 4 when the handle forming portion 3 is formed into the handle.
[0134] To form the retaining portion, the front wall forming portion 23, the rear wall forming portion 22, and the pair of side wall forming portions 21 are raised relative to the bottom forming portion 20 (see FIG. 12). At this time, the shape-retaining connecting portion 241 is placed inside the front wall forming portion 23 so as to overlap it.
[0135] Next, the base extension portion 2400 is folded back toward the rear side, so that the base extension portion 2400 overlaps the shape-retaining connecting portion 241 toward the rear side, and further, the tip extension portion 2401 is inserted into the cut line 2402 (see Figures 13(a) and 13(b)).
[0136] In this way, the shape-retaining connecting portion 241 is maintained in a state in which it is overlapped on the rear side of the front wall forming portion 23, and the front wall forming portion 23, rear wall forming portion 22 and a pair of side wall forming portions 21 are maintained in a raised state relative to the bottom forming portion 20, thereby forming a retaining portion.
[0137] Next, the reinforcing portion 4 is folded in half along the folding line 42 to form the reinforcing portion T3 (see FIG. 14).
[0138] To form the handle, the handle extension 30 is folded at the boundary between the handle extension 30 and the rear wall forming portion 22 (at the rear edge 220 of the rear wall forming portion 22) relative to the rear wall forming portion 22. At this time, the reinforcement-side folded portion 310 is folded inward and overlaps the handle-side folded portion 311 (see FIG. 15).
[0139] Furthermore, by folding the left handle-side folded portion 311 at the boundary with the handle extension 30 (at the position of the left side 300 of the handle extension 30), the left handle-side folded portion 311 is raised relative to the handle extension 30, and by folding the right handle-side folded portion 311 at the boundary with the handle extension 30 (at the position of the right side 300 of the handle extension 30), the right handle-side folded portion 311 is also raised relative to the handle extension 30 (see FIG. 16(a)). In this way, the rear ends of the pair of reinforcing portions 4 approach each other and abut against the handle extension 30.
[0140] Then, the base-side extension portion 3201 is inserted into the cut line 321 formed in the left handle-side folding portion 311. In this way, the handle T2 is formed, and the shape of the handle T2 is maintained (see FIG. 16(b)). In this way, the assembly sheet 1 is assembled into the handled tool T (see 17(a)).
[0141] In the handled tool T, the reinforcing part T3 extending rearward from the rearward corner of the holding part T1 abuts against the back surface of the handle part T2 (the back surface of the top surface of the handle T2), and the reinforcing part T3 functions like a diagonal brace between the holding part T1 and the handle T2 (see FIG. 10(b)). Therefore, even if a load is applied to the holding part T1 when the user is scooping up a tangible object with the holding part T1 while grasping the handle T2 or when the holding part T1 is receiving a tangible object, the boundary between the holding part T1 and the handle T2 is less likely to bend.
[0142] This prevents the handle tool T from being uncomfortable to use due to the holding part T1 moving relative to the handle T2. In addition, because the handle T2 itself is less likely to bend, it is also possible to prevent the handle tool T from being uncomfortable to use due to the holding part T1 moving as the handle T2 bends.
[0143] As described above, according to the assembly sheet 1 of this embodiment, when it is assembled to the handled tool T, the reinforcing part T3 formed by the reinforcing forming part 4 is configured to extend rearward from the rear end of the holding part T1 and abut against the back surface of the handle T2, so that even if a load is applied to the holding part T1 while holding the handle T2 in use, the reinforcing part T3 functions like a diagonal brace between the holding part T1 and the back surface of the handle T2, thereby preventing the holding part T1 from moving around the boundary with the handle T2 as a base point.
[0144] Therefore, the assembly sheet 1 of this embodiment allows the user to assemble the handled tool T in a comfortable manner.
[0145] Furthermore, in the assembly sheet 1 of the present invention, the tip of the fold line 42 of the left reinforcing formation portion 4 and the tip of the fold line 42 of the right reinforcing formation portion 4 are arranged symmetrically in the width direction, so that the reinforcing portion T3 formed by the left reinforcing formation portion 4 and the reinforcing portion T3 formed by the right reinforcing formation portion 4 can be easily abutted against the back surface of the handle T2 when they are arranged symmetrically on the left and right sides. Therefore, when a load is applied to the holding portion T1 while holding the handle T2 and using it, the reinforcing portion T3 formed by the left reinforcing formation portion 4 and the reinforcing portion T3 formed by the right reinforcing formation portion 4 can support the holding portion T1 in a balanced manner in the width direction relative to the handle T2, thereby preventing the holding portion T1 from tilting or the handle T2 from twisting.
[0146] Furthermore, in the assembly sheet 1 of this embodiment, the folding portion 31 for the left handle can be bent so that it overlaps the left reinforcing forming portion 4 on the outward side, and the folding portion 31 for the right handle can be bent so that it overlaps the right reinforcing forming portion 4 on the outward side. Therefore, the folding portion 31 for the left handle prevents the position of the reinforcing portion T3 formed by the left reinforcing forming portion 4 from shifting outward, and the folding portion 31 for the right handle prevents the position of the reinforcing portion T3 formed by the right reinforcing forming portion 4 from shifting outward. Therefore, when a load is applied to the holding portion T1 while the handle T2 is being held and used, the reinforcing portion T3 formed by the left reinforcing forming portion 4 and the reinforcing portion T3 formed by the right reinforcing forming portion 4 can easily maintain a state in which they support the holding portion T1 in a balanced manner in the width direction relative to the handle T2.
[0147] Furthermore, in the assembled sheet 1 of this embodiment, the reinforcing portion T3 formed by the left reinforcing portion 4 and the reinforcing portion T3 formed by the right reinforcing portion 4 are connected to the pattern T2 (side surface of the pattern T2), so the reinforcing portion T3 formed by the left reinforcing portion 4 and the reinforcing portion T3 formed by the right reinforcing portion 4 are less likely to move relative to the pattern T2. This makes it less likely that the holding portion T1 will move relative to the pattern T2.
[0148] Furthermore, since the left-handle fold-in portion 31 is foldably connected to the left reinforcing formation portion 4 and the right-handle fold-in portion 31 is foldably connected to the right reinforcing formation portion 4, the left reinforcing formation portion 4 and the left-handle fold-in portion 31 are foldably connected, which makes it easier to position the left reinforcing formation portion 4 in a fixed position, and since the right reinforcing formation portion 4 and the right-handle fold-in portion 31 are foldably connected, which makes it easier to position the right reinforcing formation portion 4 in a fixed position. Therefore, when a load is applied to the holding portion T1 while holding the handle T2 in use, the reinforcing portion T3 formed by the left reinforcing formation portion 4 and the reinforcing portion T3 formed by the right reinforcing formation portion 4 more easily maintain a state in which they support the holding portion T1 in a balanced manner in the width direction relative to the handle T2.
[0149] Furthermore, the assembly sheet 1 of this embodiment is configured so that the left handle folding portion 31 can be held to the right handle folding portion 31 by the retaining portion formed by the reinforcing side extension portion 320, making it easier to maintain the folded state of the pair of handle folding portions 31 and easier to maintain the shape of the assembled handle T2.
[0150] Hereinafter, a sheet for assembling a handled tool (hereinafter referred to as an assembly sheet) according to a third embodiment of the present invention will be described with reference to the accompanying drawings.
[0151] The assembly sheet according to this embodiment is also configured so that it can be assembled into a scooping tool, which is a type of handled tool having a handle that serves as a handle.
[0152] For convenience, the names of the components and the symbols attached to the names of the components described in the description of the assembly sheet of this embodiment include the same components as those described in the assembly sheet of the first embodiment above.
[0153] As shown in Figure 18, the assembly sheet 1 includes a holding portion forming portion 2 that forms a holding portion that holds a tangible object, a handle forming portion 3 that forms a handle that extends rearward from the holding portion, and a pair of reinforcing portions 4 that extend rearward from the rear end of the holding portion and form reinforcing portions that can abut against the back surface of the handle.
[0154] As shown in Figures 26(a) and 26(b), the handle attachment T comprises a holding portion T1, a handle T2 extending rearward from the holding portion T1, and a reinforcing portion T3 extending rearward from the holding portion T1 and abutting the back surface of the handle T2.
[0155] In the following description, the direction in which the holding portion forming portion 2 and the handle forming portion 3 are aligned (the direction corresponding to the top and bottom in Figure 18) is referred to as the front-to-back direction, the direction from the handle forming portion 3 side toward the holding portion forming portion 2 side (the direction toward the top in Figure 18) is referred to as the front direction, and the direction opposite to the front direction (the direction toward the bottom in Figure 18) is referred to as the rear direction.
[0156] In addition, the direction perpendicular to the front-to-back direction (the direction corresponding to the left-to-right direction in Figure 18) is referred to as the width direction, the direction toward the center line CL in the width direction is referred to as the inward direction, and the direction away from the center line CL in the width direction is referred to as the outward direction.
[0157] The tangible object held by the holding portion formed by the holding portion forming portion 2 is, for example, a powdery or granular fluid, a solid, or the like.
[0158] As shown in Figure 18, the retaining portion forming portion 2 of this embodiment has a bottom forming portion 20 that forms the bottom of the retaining portion, a pair of side wall forming portions 21 that form the side walls of the retaining portion, a rear wall forming portion 22 that forms the rear wall of the retaining portion, a front wall forming portion 23 that forms the front wall of the retaining portion, and a retaining side shape-retaining structure 24 for maintaining the shape of the assembled retaining portion.

One end (base end) of the right edge 202 intersects with the right edge of the rear edge 201, and the other end (tip end) intersects with the right edge of the front edge 200. The left edge 202 and the right edge 202 are formed so that they are spaced farther apart in the width direction as they extend further forward.
[0162] The pair of side wall forming portions 21 are rectangular.
[0163] The pair of side wall forming portions 21 have a front edge 210 that extends outward from the front edge 200 (end of the front edge 200) of the bottom forming portion 20 and has a tip that is shifted forward from the base end, a rear edge 211 that extends outward from the rear edge 201 (end of the rear edge 201) of the bottom forming portion 20 and has a tip that is shifted rearward from the base end, an inner edge that is the same part as either the left edge 202 or the right edge 202 of the bottom forming portion 20, and an outer edge 212 that is aligned with the inner edge in the width direction and forms part of the outline of the assembly sheet 1.
[0164] The front edge 210 and the rear edge 211 are aligned in the front-to-rear direction. In this embodiment, no fold line is formed at the boundary between the side wall forming portion 21 and the reinforcing forming portion 4. In this embodiment, the pair of side wall forming portions 21 have symmetrical shapes with respect to the center line CL.
[0165] The rear wall forming portion 22 is rectangular. The rear wall forming portion 22 has a front side that is the same as the rear side 201 of the bottom forming portion 20, a rear side 220 that is aligned with the front side in the front-to-rear direction, and a pair of side sides 221 that are aligned in the width direction. Hereinafter, the side side 221 illustrated on the left side in FIG. 18 will be referred to as the left side 221, and the side side 221 illustrated on the right side in FIG. 18 will be referred to as the right side 221.
[0166] The front and rear edges 220 are parallel to each other. The left edge 221 extends rearward from the rear end of the left edge 202 of the bottom forming portion 20, and the right edge 221 extends rearward from the rear end of the right edge 202 of the bottom forming portion 20. The left edge 221 and the right edge 221 are also parallel to each other.
[0167] The front wall forming portion 23 is rectangular. The front wall forming portion 23 has a front edge 230 located on the front side, a rear edge that is aligned with the front edge 230 in the front direction and is the same part as the front edge 200 of the bottom forming portion 20, and a pair of side edges 231 that are aligned in the width direction. Hereinafter, the side edge 231 illustrated on the left side in FIG. 18 will be referred to as the left side edge 231, and the side edge 231 illustrated on the right side in FIG. 18 will be referred to as the right side edge 231.
[0168] The front edge 230 and the rear edge are parallel to each other. The left edge 231 extends forward from the front end of the left edge 202 of the bottom forming portion 20, and the right edge 231 extends forward from the front end of the right edge 202 of the bottom forming portion 20.
[0169] The left side 231 and the right side 231 are inclined so that they are positioned more inward as they move forward, and therefore the left side 231 and the right side 231 are formed so that they approach each other in the width direction as they move forward.
[0170] The retaining side shape-retaining structure 24 has a shape-retaining extension portion 240 extending forward from the front wall forming portion 23, and a pair of shape-retaining connecting portions 241 connected to one of the left side edge 231 or the right side edge 231 of the front wall forming portion 23 and the front edge 210 of the side wall forming portion 21.
[0171] The shape-retaining extension portion 230 has a base-side extension portion 2400 that extends forward from the front edge of the front wall forming portion 23, and a tip-side extension portion 2401 that extends forward from the base-side extension portion 2400.
[0172] The base-side extending portion 2400 is rectangular. The base-side extending portion 2400 has a front side and a rear side that are aligned in the front-rear direction and parallel to each other, and a pair of side sides that are aligned in the width direction. The rear side of the base-side extending portion 2400 is the same part as the front side 230 of the front wall forming portion 23.
[0173] The distal extension 2401 is semicircular. The rear side of the distal extension 2401 is the same as the front side of the base extension 2400. The front side of the distal extension 2401 is formed in an arc shape.
[0174] Further, the front extension portion 2401 is formed with a curved bending line 2402, and is configured so as to be able to bend at the position of this bending line 2402.
[0175] 18, a fold line 2410 is formed that extends linearly from the intersection of the left side 231 of the front wall forming portion 23 and the front side 210 of the side wall forming portion 21. Therefore, the shape-retaining continuous portion 241 is configured so that it can be folded in half at the position of the fold line 2410.
[0176] 18, a fold line 2410 is formed that extends linearly from the intersection of the right side 231 of the front wall forming portion 23 and the front side 210 of the side wall forming portion 21. Therefore, the shape-retaining continuous portion 241 is configured so that it can be folded in half at the position of the fold line 2410.
[0177] Here, the reinforcement forming portion 4 will be described. One of the pair of reinforcement forming portions 4 (the reinforcement forming portion 4 located on the left side in FIG. 18) is a first reinforcement forming portion 4, which will be referred to hereinafter as the left reinforcement forming portion 4. The other of the pair of reinforcement forming portions 4 (the reinforcement forming portion 4 located on the right side in FIG. 18) is a second reinforcement forming portion 4, which will be referred to hereinafter as the right reinforcement forming portion 4.
[0178] The reinforcing forming portion 4 has a rear edge 40, an inner edge which is the same part as the side edge 221 of the rear wall forming portion 22, and an outer edge 41 which is aligned with the inner edge in the width direction and which forms part of the outline of the assembled sheet 1.
[0179] 18, a fold line 42 is formed in a straight line from the intersection of the rear edge 201 of the bottom forming portion 20 and the left edge 221 of the rear wall forming portion 22 toward the rear edge 40 of the reinforcement forming portion 4 itself, and is bendable. Therefore, this fold line 42 extends outward and rearward from the intersection of the rear edge 201 of the bottom forming portion 20 and the left edge 221 of the rear wall forming portion 22.
[0180] 18, a fold line 42 is formed in a straight line from the intersection of the rear edge 201 of the bottom forming portion 20 and the right edge 221 of the rear wall forming portion 22 toward the rear edge 40 of the reinforcement forming portion 4 itself, and is bendable. Therefore, this fold line 42 extends outward and rearward from the intersection of the rear edge 201 of the bottom forming portion 20 and the rear edge 221 of the rear wall forming portion 22.
[0181] The handle forming portion 3 has a handle extension portion 30 extending rearward from the rear edge 220 of the rear wall forming portion 22, a pair of handle folding portions 31 connected adjacent to the handle extension portion 30 on the outward side, and a handle side shape retention structure 32 for maintaining the shape of the assembled handle.
[0182] The handle extension 30 has a front side that is formed of the same part as the rear side 220 of the rear wall forming portion 22, and a pair of side sides 300 that extend rearward from different ends of the front side. Hereinafter, the side side 300 shown on the left side in Fig. 1 will be referred to as the left side 300, and the side side 300 shown on the right side in Fig. 1 will be referred to as the right side 300.
[0183] The left side 300 and the right side 300 are configured to approach each other as they move toward the rear.
[0184] Each of the pair of handle folding portions 31 has a handle side folding portion 310 connected to the handle extension portion 30. In the following description, the handle folding portion 30 and handle side folding portion 310 located to the left of the center line CL in Fig. 18 will be referred to as the left handle folding portion 30 and left handle side folding portion 310. In addition, in the following description, the handle folding portion 30 and handle side folding portion 310 located to the right of the center line CL in Fig. 18 will be referred to as the right handle folding portion 30 and right handle side folding portion 310.
[0185] The left handle-side folded portion 310 is connected to the left side 300 of the handle extension portion 30 , and the right handle-side folded portion 310 is connected to the right side 300 of the handle extension portion 30 .
[0186] The left handle side fold portion 310 and the right handle side fold portion 310 have a fold line 3100 formed therein, and can be folded in half so that the portion on the outer side of the fold line 3100 overlaps the portion on the inner side of the fold line 3100. The left handle side fold portion 310 is discontinuous with the left reinforcing forming portion 4, and the right handle side fold portion 310 is discontinuous with the left reinforcing forming portion 4.
[0187] The handle side shape-retaining structure 32 has a pair of reinforcement side extensions 320 extending from the reinforcement forming portion 4 and a pair of handle side extensions 321 extending from the handle side folded-in portion 310. The reinforcement side extensions 320 and handle side extensions 321 located to the left of the center line CL in Fig. 18 will be referred to as the left reinforcement side extensions 320 and left handle side extensions 321 in the following description. The reinforcement side extensions 320 and handle side extensions 321 located to the right of the center line CL in Fig. 18 will be referred to as the right reinforcement side extensions 320 and right handle side extensions 321 in the following description.
[0188] The pair of reinforcement side extension portions 320 are formed so as to extend rearward from the reinforcement forming portion 4 .
[0189] The left reinforcing side extension portion 320 is configured to be disposed between the base end side and the tip end side of the left handle side fold-in portion 310 when the left handle side fold-in portion 310 is folded in half.
[0190] The right reinforcing side extension portion 320 is configured to be disposed between the base end side and the tip end side of the right handle side fold-in portion 310 when the right handle side fold-in portion 310 is folded in half.
[0191] The left handle extension 321 is formed with an extended claw 3210 that extends outward.
[0192] At the boundary between the right handle side extension portion 321 and the right handle side fold-in portion 310, a cut line 3211 is formed that penetrates through both sides.
[0193] The right handle side folding portion 310 is configured so that it can be folded in half and placed on the back surface of the handle extension portion 30. The left handle side folding portion 310 is configured so that it can be folded in half and placed on the back surface of the handle extension portion 30, and the extension claw portion 3210 can be inserted into the cut line 3211.
[0194] When the extended claw portion 3210 is inserted into the cut line 3211, the left handle side extended portion 321 holds the right handle folding portion 31 against the right handle folding portion 31. In this way, the left handle side extended portion 321 constitutes a holding portion that holds the left handle folding portion 31 against the right handle folding portion 31.
[0195] The above is the configuration of the assembly sheet 1 according to this embodiment. Next, a method for assembling the assembly sheet 1 into a handle-equipped tool will be described.
[0196] The assembly sheet 1 of this embodiment is assembled into a handle tool by forming the holding portion forming portion 2 into the holding portion and the handle forming portion 3 into the handle, and after forming the holding portion forming portion 2 into the holding portion, a reinforcing portion is formed by the reinforcing forming portion 4 when the handle forming portion 3 is formed into the handle.
[0197] To form the holding portion, the front wall forming portion 23, the rear wall forming portion 22, and the pair of side wall forming portions 21 are raised relative to the bottom forming portion 20 (see FIGS. 19 and 20).
[0198] At this time, when the shape-retaining connecting portion 241 is folded in half along the folding line 2410 and the front edge of the left side wall forming portion 21 is positioned near the left edge 230 of the front wall forming portion 23 and the front edge of the right side wall forming portion 21 is positioned near the right edge 230 of the front wall forming portion 23, the front edges of the pair of side wall forming portions 21 are brought inward. Therefore, the pair of side wall forming portions 21 are curved so as to bulge outward.
[0199] Next, the shape-retaining connecting portion 241, which is folded in half, is bent inward and moved forward of the outer surface of the front wall forming portion 23 (see FIG. 21). Furthermore, the base-side extending portion 2400 is bent at the boundary between the front wall forming portion 23 and the base-side extending portion 2400, so that the base-side extending portion 2400 overlaps the front side of the front wall forming portion 23, and further, the tip-side extending portion 2401 is inserted between the shape-retaining connecting portion 241 and the front wall forming portion 23 (see FIG. 22).
[0200] The tip-side extension portion 2401 can be bent at the portion closer to the tip than the curved fold line toward the portion closer to the base end than the curved fold line, making it easier to insert the portion closer to the tip than the curved fold line between the shape-retaining connecting portion 241 and the front wall forming portion 23.
[0201] In this way, the front wall forming portion 23, the rear wall forming portion 22, and the pair of side wall forming portions 21 are maintained in an upright state relative to the bottom forming portion 20, forming a holding portion.
[0202] Furthermore, since the shape-retaining connecting portion 241 is arranged with the base extension portion 2400 overlapping on the forward side, the state in which it is folded in half along the fold line is maintained, and thereby the pair of side wall forming portions 21 are also maintained in a curved state in which they bulge outward.
[0203] Next, the reinforcing portion 4 is folded in half along the folding line 42 to form the reinforcing portion T3 (see FIG. 23).
[0204] To form the handle, the right handle-side folded-in portion 310 is folded in half so that the right reinforcing-side extension portion 320 is positioned inside the right handle-side folded-in portion 310 (see FIG. 24).
[0205] Furthermore, the left handle side folded-in portion 310 is also folded in half so that the left reinforcing side extension portion 320 is disposed inside the left handle side folded-in portion 310.
[0206] Then, the extended claw portion 3210 is inserted into the cut line 3211. In this way, the handle T2 is formed, and the shape of the handle T2 is maintained (see FIG. 25). In this way, the assembly sheet 1 is assembled into the handled tool T (see FIG. 26(a)).
[0207] In the handled tool T, the reinforcing part T3 extending rearward from the rearward corner of the holding part T1 abuts against the back surface of the handle part T2 (the back surface of the top surface of the handle T2), and the reinforcing part T3 functions like a diagonal brace between the holding part T1 and the handle T2 (see FIG. 26(b)). Therefore, even if a load is applied to the holding part T1 when the user is scooping up a tangible object with the holding part T1 while grasping the handle T2 or when the holding part T1 is receiving a tangible object, the boundary between the holding part T1 and the handle T2 is less likely to bend.
[0208] This prevents the handle tool T from being uncomfortable to use due to the holding part T1 moving relative to the handle T2.
[0209] Furthermore, since the handle T2 itself is less likely to bend, it is possible to prevent the handle T2 from bending and causing the holding part T1 to move, which would otherwise cause discomfort when using the tool.
[0210] As described above, according to the assembly sheet 1 of this embodiment, when it is assembled to the handled tool T, the reinforcing part T3 formed by the reinforcing forming part 4 is configured to extend rearward from the rear end of the holding part T1 and abut against the back surface of the handle T2, so that even if a load is applied to the holding part T1 while holding the handle T2 in use, the reinforcing part T3 functions like a diagonal brace between the holding part T1 and the back surface of the handle T2, thereby preventing the holding part T1 from moving around the boundary with the handle T2 as a base point.
[0211] Therefore, the assembly sheet 1 of this embodiment allows the user to assemble the handled tool T in a comfortable manner.
[0212] Furthermore, in the assembly sheet 1 of the present invention, the tip of the fold line 42 of the left reinforcing formation portion 4 and the tip of the fold line 42 of the right reinforcing formation portion 4 are arranged symmetrically in the width direction, so that the reinforcing portion T3 formed by the left reinforcing formation portion 4 and the reinforcing portion T3 formed by the right reinforcing formation portion 4 can be easily abutted against the back surface of the handle T2 when they are arranged symmetrically on the left and right sides. Therefore, when a load is applied to the holding portion T1 while holding the handle T2 and using it, the reinforcing portion T3 formed by the left reinforcing formation portion 4 and the reinforcing portion T3 formed by the right reinforcing formation portion 4 can support the holding portion T1 in a balanced manner in the width direction relative to the handle T2, thereby preventing the holding portion T1 from tilting or the handle T2 from twisting.
[0213] Furthermore, in the assembly sheet 1 of this embodiment, the folding portion 31 for the left handle can be bent so that it overlaps the left reinforcing forming portion 4 on the outward side, and the folding portion 31 for the right handle can be bent so that it overlaps the right second reinforcing forming portion 4 on the outward side. Therefore, the folding portion 31 for the left handle prevents the position of the reinforcing portion T3 formed by the left reinforcing forming portion 4 from shifting outward, and the folding portion 31 for the right handle prevents the position of the reinforcing portion T3 formed by the right reinforcing forming portion 4 from shifting outward. Therefore, when a load is applied to the holding portion T1 while holding the handle T2 and using it, the reinforcing portion T3 formed by the left reinforcing forming portion 4 and the reinforcing portion T3 formed by the right reinforcing forming portion 4 will more easily maintain a state in which they support the holding portion T1 in a balanced manner in the width direction relative to the handle T2.
[0214] Furthermore, the assembly sheet 1 of this embodiment is configured so that the left-handle folding portion 31 can be held to the right-handle folding portion 31 by the retaining portion formed by the left-handle extension portion 321, making it easier to maintain the folded state of the pair of handle folding portions 31 and easier to maintain the shape of the assembled handle.
[0215] The handle tool assembling sheet according to the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made within the scope of the present invention.
[0216] Although not specifically mentioned in the description of the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, and the assembly sheet 1 of the E3 embodiment, the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, and the assembly sheet 1 of the third embodiment may be paper, paper whose surface is coated with resin, or paper impregnated with resin.
[0217] Furthermore, the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, and the assembly sheet 1 of the third embodiment may be made of resin or wood, as long as it is possible to assemble the handle-equipped tool using the assembly method described above.
[0218] Although not specifically mentioned in the description of the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, and the assembly sheet 1 of the third embodiment, the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, and the assembly sheet 1 of the third embodiment may be capable of assembling, for example, measuring spoons, spoons for eating and drinking, and sporks, or may be capable of assembling forks and the like as long as they are capable of holding tangible objects.
[0219] In addition, when the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, or the assembly sheet 1 of the third embodiment is configured so that it can be assembled into a measuring spoon, the tangible object held by the holding portion becomes the object to be measured.
[0220] Furthermore, when the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, or the assembly sheet 1 of the third embodiment is configured to be assembled into, for example, a spork or a fork, it is preferable that it be reinforced with resin or the like.
[0221] Furthermore, the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, and the assembly sheet 1 of the third embodiment may be capable of assembling, for example, an object that does not have a front wall forming portion 23 (for example, a tool with a handle used as a dustpan that holds (receives) tangible objects such as dust, sand, etc.).
[0222] Although not specifically mentioned in the description of the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, or the assembly sheet 1 of the third embodiment, the assembly sheet 1 of the first embodiment, the assembly sheet 1 of the second embodiment, or the assembly sheet 1 of the third embodiment may have a shape that is inverted left and right with respect to the center line CL.
[0223] The handle side shape-retaining structure 32 in the first embodiment described above is configured to have a pair of handle side extension portions 321 (left handle side extension portion 321 and right handle side extension portion 321), but is not limited to this configuration.
[0224] For example, the handle side shape retention structure 32 may be configured to have only the right handle side extension portion 321 out of the left handle side extension portion 321 and the right handle side extension portion 321, or may be configured to have only the left handle side extension portion 321, as long as it can maintain the pair of handle folding portions 31 folded relative to the handle extension portion 30.
[0225] The pair of handle folding portions 31 are more likely to move apart in the width direction on the front side than on the rear side. The right handle extension portion 321 is configured to connect the pair of handle folding portions 31 to each other at a position further forward than the left handle extension portion 321. Therefore, the handle shape-retaining structure 32 is more likely to maintain the shape of the handle when configured with only the right handle extension portion 321 than when configured with only the left handle extension portion 321.
[0226] The handle side shape-retaining structure 32 in the first embodiment described above was configured to have a pair of reinforcement side extension portions 320 (left reinforcement side extension portion 320 and right reinforcement side extension portion 320), but is not limited to this configuration.
[0227] For example, the handle side shape-retaining structure 32 may be configured to have only the right reinforcement side extension portion 320 out of the left reinforcement side extension portion 320 and the right reinforcement side extension portion 320. However, if the handle side shape-retaining structure 32 has the right handle side extension portion 321, the left reinforcement side extension portion 320 will be necessary.
[0228] Furthermore, the handle side shape-retaining structure 32 may be configured to have only the left reinforcing side extension portion 320 out of the left reinforcing side extension portion 320 and the right reinforcing side extension portion 320. However, since the right reinforcing side extension portion 320 plays a role in forming a valley for arranging the pair of reinforcing portions T3 together with the right reinforcing side fold-in portion 310, configuring the handle side shape-retaining structure 32 to have the right reinforcing side extension portion 320 makes it easier to maintain a high reinforcing effect of the pair of reinforcing portions T3 on the handle T2.
