Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the bar of Patent Document 1 has limited uses, such as pulling out nails or prying open a door, and lacks versatility. One aspect of the present disclosure provides a highly versatile tool while having the function as a bar.

Means for Solving the Problems

[0005] One aspect of the present disclosure is a crowbar / pry bar tool. The crowbar / pry bar tool comprises a rod-shaped portion, an engaging portion, and a flattened portion. The rod-shaped portion is a metal rod-shaped member. The engaging portion is provided at a first end, which is one end of the rod-shaped portion, and is configured to detachably attach to a predetermined object having an engaged portion that can engage with the engaging portion. The flattened portion is a metal member that protrudes from a second end, which is the end of the rod-shaped portion opposite to the first end. The flattened portion is a virtual rectangle that encloses a cross section perpendicular to the direction in which the flattened portion protrudes, and when a rectangle is drawn tangent to the outer circumference of the cross section, the length of the first side, which is one side of the rectangle, and the length of the second side perpendicular to the first side are different.

[0006] With this configuration, the flattened portion has a flattened shape in the cross-section perpendicular to the direction in which the flattened portion protrudes. Therefore, for example, a user can insert the flattened portion into a gap in rubble and use the lever principle to use the crowbar / crowbar tool as a crowbar. Also, when an object is attached to the engaging portion, the user can use the function of the object. Therefore, a user can use the crowbar / crowbar tool for other functions in addition to its function as a crowbar. Thus, the versatility of the crowbar / crowbar tool can be increased compared to a tool that can only be used as a crowbar.

[0007] In one aspect of this disclosure, the flattened portion may have a through-hole that penetrates the flattened portion in the thickness direction. With such a configuration, for example, the through-hole can be hooked onto a hook or the like. Therefore, the crowbar / tool ​​can be suspended and stored, making effective use of storage space.

[0008] In one aspect of this disclosure, the rod-shaped portion may have a tensile strength of 780 MPa or more. With such a configuration, the strength of the rod-shaped portion can be increased, and the weight can be reduced.

[0009] In one aspect of this disclosure, the flattened portion may have a tensile strength of 780 MPa or more. With such a configuration, the strength of the flattened portion can be increased, and weight reduction can be achieved.

[0010] In one aspect of this disclosure, the rod-shaped portion may be configured in a cylindrical shape. The second end of the rod-shaped portion may be closed. With such a configuration, the strength of the second end of the rod-shaped portion can be increased compared to a configuration in which the second end of the rod-shaped portion is open.

[0011] In one aspect of this disclosure, the engaging portion and the engaged portion may be hollow with an internal space. The engaging portion may have a first hole that penetrates the side wall of the engaging portion in a direction perpendicular to the direction in which the engaging portion extends. The engaged portion may have a second hole that penetrates the side wall of the engaged portion in a direction perpendicular to the direction in which the engaged portion extends. An elastic member having elasticity may be disposed in the internal space of the engaging portion or the engaged portion. The elastic member may have a projection. The projection may be provided so as to protrude toward the external space. When the engaged portion is inserted into the engaging portion, or when the engaging portion is inserted into the engaged portion, the projection is pushed toward the elastic member, and when the first hole and the second hole overlap, the projection penetrates the first hole and the second hole, and the engaging portion and the engaged portion may engage.

[0012] With this configuration, the engaging part and the engaged part can be engaged simply by inserting the engaged part into the engaging part. Therefore, the object can be easily attached to the crowbar / pry bar tool.

[0013] One aspect of the present disclosure is a sasumata (a type of pole weapon). The sasumata comprises a crowbar / crowbar combination tool and a restraining tool. The crowbar / crowbar combination tool comprises a rod-shaped portion, an engaging portion, and a flattened portion. The rod-shaped portion is a metal rod-shaped member. The engaging portion is provided at a first end, which is one end of the rod-shaped portion, and is configured to be detachably attached to a predetermined object having an engaged portion that can engage with the engaging portion. The flattened portion is a metal member protruding from a second end, which is the end of the rod-shaped portion opposite to the first end. The flattened portion is a virtual rectangle that surrounds a cross section perpendicular to the direction in which the flattened portion protrudes, and when a rectangle is drawn tangent to the outer circumference of the cross section, the length of the first side, which is one side of the rectangle, and the length of the second side perpendicular to the first side are different. The restraining tool is configured to be detachably attached to the engaging portion as an object. The restraining tool also comprises a pressing portion and an engaged portion. The pressing portion is a substantially U-shaped member. The engaged portion is a member that extends from a position spaced apart from both ends of the pressing portion, in the direction in which the pressing portion is recessed.

[0014] With this configuration, the flattened portion has a flattened shape in the cross-section perpendicular to the direction in which the flattened portion protrudes. Therefore, for example, a user can insert the flattened portion into a gap in rubble and use the lever principle to use the sasumata as a crowbar. Thus, a user can use the sasumata not only as a sasumata but also as a crowbar. Therefore, the versatility of the sasumata can be increased compared to a tool that can only be used as a sasumata.

[Modes for carrying out the invention]

[0016] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. Embodiments] [1-1. Crowbar / crowbar combination tool] The multi-functional tool 1 shown in FIG. 1A is a tool that has a function as a bar and functions other than the function as a bar. In the present embodiment, the multi-functional tool 1 has, in addition to the function as a bar, functions as a cleaning tool and a security tool. The multi-functional tool 1 includes a rod-shaped portion 11, an engaging portion 12, and a flat portion 13. Hereinafter, the direction in which the rod-shaped portion 11 extends is defined as the vertical direction, the direction in which the engaging portion 12 is provided is defined as the downward direction, and the direction in which the flat portion 13 is provided is defined as the upward direction. Further, the thickness direction of the flat plate portion 29 described later is defined as the front-rear direction. The thickness direction of the flat plate portion 29 is a direction in which the thickness of the flat plate portion 29 is relatively thin. Further, the direction orthogonal to the vertical direction and the front-rear direction is defined as the left-right direction. These directions are defined for the convenience of explanation and do not limit the usage mode of the multi-functional tool 1.

[0017] The rod-shaped portion 11 is a rod-shaped member made of metal. The rod-shaped portion 11 is configured in a cylindrical shape in which the central axes in the longitudinal direction of the rod-shaped portion 11 coincide. In other words, the rod-shaped portion 11 is configured in a hollow shape having an internal space. Specifically, the rod-shaped portion 11 is a cylindrical pipe made of a high-tensile material having a tensile strength of 780 MPa or more.

[0018] An engaging portion 12 is provided at a first end portion 21 which is one end of the rod-shaped portion 11. A flat portion 13 is provided at a second end portion 22 which is the end portion of the rod-shaped portion 11 opposite to the first end portion 21.

[0019] The engaging portion 12 is a portion for attaching a predetermined object. The engaging portion 12 is configured to be able to attach and detach the object. The engaging portion 12 is provided at the first end portion 21 of the rod-shaped portion 11. In the present embodiment, the objects are the head 4 of the broom and the tip portion 5 of the spear. The objects will be described in detail later.

[0020] As shown in FIG. 2, the engaging portion 12 includes a large-diameter portion 24, a small-diameter portion 25, and a diameter-expanded portion 27. The large-diameter portion 24 is a cylindrical member configured in a hollow shape having an internal space. The diameter of the large-diameter portion 24 is configured to be slightly larger than the diameter of the rod-shaped portion 11.

[0021] The small-diameter portion 25 is also a cylindrical member configured to be hollow with an internal space. The diameter of the small-diameter portion 25 is smaller than the diameter of the rod-shaped portion 11 and the diameter of the large-diameter portion 24. The small-diameter portion 25 has a first hole 26 that penetrates the side wall of the small-diameter portion 25 in a direction perpendicular to the direction in which the small-diameter portion 25 extends. The first hole 26 is formed in the small-diameter portion 25 approximately in the center in the direction in which the small-diameter portion 25 extends. In other words, the first hole 26 is formed in the small-diameter portion 25 approximately in the center in the vertical direction.

[0022] The enlarged diameter section 27 is positioned between the small diameter section 25 and the large diameter section 24, and is a member that connects the small diameter section 25 and the large diameter section 24. The enlarged diameter section 27 is configured to be hollow with an internal space. The enlarged diameter section 27 is configured to be tapered so that its diameter increases from the small diameter section 25 towards the large diameter section 24.

[0023] The first end 21 of the rod-shaped portion 11 is inserted into the large-diameter portion 24, and the large-diameter portion 24 and the rod-shaped portion 11 are fixed together by welding. The flattened portion 13 shown in Figure 3 is a metal member that protrudes from the second end 22 of the rod-shaped portion 11. The flattened portion 13 is a member manufactured using high-tensile steel with a tensile strength of 780 MPa or more. The flattened portion 13 comprises a cylindrical portion 28 and a flat plate portion 29.

[0024] The cylindrical portion 28 is a hollow cylindrical member with an internal space. The diameter of the cylindrical portion 28 is slightly larger than the diameter of the rod-shaped portion 11. One end of the cylindrical portion 28, the third end 31, is open, while the end opposite to the third end 31, the fourth end 32, is closed.

[0025] The flat plate portion 29 is a plate-shaped member. When viewed from the front, the flat plate portion 29 has a roughly rectangular shape. In other words, the flat plate portion 29 has planes that extend in the vertical and horizontal directions. The two corners in the protruding direction (in other words, the upward direction) are chamfered. The type of chamfering is not limited to this; it may be a C-chamfer or an R-chamfer.

[0026] Half of the flat plate portion 29 is fixed in the cylindrical portion 28, inserted into it along its longitudinal direction. More specifically, half of the flat plate portion 29 in the longitudinal direction is inserted into the cylindrical portion 28 from the fourth end 32 of the cylindrical portion 28 to approximately the center in the direction in which the cylindrical portion 28 extends. The remaining half of the flat plate portion 29 in the longitudinal direction protrudes from the fourth end 32 of the cylindrical portion 28. In other words, the lower half of the flat plate portion 29 is fixed in the cylindrical portion 28, while the upper half of the flat plate portion 29 protrudes upward from the fourth end 32 of the cylindrical portion 28.

[0027] The short-side end of the flat plate portion 29 may protrude from the outer surface of the cylindrical portion 28, as shown in Figure 1A, or it may be flush with the outer surface of the cylindrical portion 28, as shown in Figure 3. In other words, the length of the flat plate portion 29 in the left-right direction may be longer than the diameter of the cylindrical portion 28, or it may be approximately the same as the diameter of the cylindrical portion 28. Also, the length of the flat plate portion 29 in the left-right direction may be shorter than the diameter of the cylindrical portion 28.

[0028] The second end 22 of the rod-shaped portion 11 is inserted into the cylindrical portion 28 from the third end 31 of the cylindrical portion 28 to approximately the center in the direction in which the cylindrical portion 28 extends, and the cylindrical portion 28 and the rod-shaped portion 11 are fixed together by welding. In other words, the second end 22 of the rod-shaped portion 11 is closed off because it is covered by the cylindrical portion 28.

[0029] The flat plate portion 29 has a through hole 33 that penetrates it in the thickness direction. More specifically, the flat plate portion 29 has a through hole 33 that penetrates it in a direction perpendicular to the direction in which the flat plate portion 29 protrudes, and in a direction in which the thickness of the flat plate portion 29 is relatively thin. In other words, the through hole 33 is formed to penetrate the flat plate portion 29 in the front-to-back direction. The through hole 33 is formed approximately in the center of the portion of the flat plate portion 29 that protrudes from the fourth end 32 of the cylindrical portion 28.

[0030] [1-2. Object] [1-2-1. Broom head] The broom head 4 shown in Figure 1B comprises a base portion 41, a bristles portion 42, and an engagement portion 43.

[0031] The base portion 41 is a long, rectangular member. The material of the base portion 41 is not limited; for example, it may be made of wood or resin. The bristles portion 42 is a brush-like part that comes into contact with dust and other debris when the broom is used. The bristles portion 42 extends from the base portion 41 along one of its longitudinal sides. The material of the bristles portion 42 is not limited; for example, it may be made of fern or synthetic fiber.

[0032] The engaged portion 43 is configured to be engageable with the engaging portion 12. More specifically, the engaged portion 43 is a cylindrical member configured to be hollow with an internal space. The diameter of the engaged portion 43 is slightly smaller than the diameter of the small diameter portion 25. The engaged portion 43 is provided approximately in the center of the longitudinal direction of the base portion 41. The engaged portion 43 is provided so as to extend from the base portion 41 in a direction intersecting the base portion 41. The engaged portion 43 is provided on the side of the base portion 41 opposite to the side where the bristles portion 42 is located. The engaged portion 43 may be fixed so as to extend from the base portion 41 in a direction perpendicular to the base portion 41, or it may be rotatably connected to the base portion 41. The shape of the base portion 41 and the bristles portion 42 is not limited to the shapes described above, as long as they are shapes that can function as a broom.

[0033] The engaged portion 43 has a second hole 44 that penetrates the side wall of the engaged portion 43 in a direction perpendicular to the direction in which the engaged portion 43 extends. The second hole 44 is formed at a position further from the base portion 41 than approximately the center in the direction in which the engaged portion 43 extends.

[0034] As shown in Figures 4A to 4C, an elastic member 45 is placed in the internal space of the engaged portion 43. In this embodiment, a leaf spring, which is a long, metal plate, is used as the elastic member 45. More specifically, the leaf spring is placed in the internal space of the engaged portion 43 in a state where it is bent into a roughly U-shape. Both ends of the leaf spring face in the opposite direction to the base portion 41. Hereinafter, with respect to the leaf spring, the side that is relatively closer to the side wall of the engaged portion 43 (in other words, the side that forms the outer circumference of the roughly U-shape) will be referred to as the outer surface, and the side that is relatively farther from the side wall of the engaged portion 43 (in other words, the side that forms the inner circumference of the roughly U-shape) will be referred to as the inner surface.

[0035] The elastic member 45 is provided with a metallic projection 46. In this embodiment, the projection 46 is provided near one end of the leaf spring. The projection 46 protrudes from the outer surface of the leaf spring in a direction perpendicular to the leaf spring. In other words, the projection 46 is provided so as to protrude from the leaf spring toward the outer space from the internal space of the engaged portion 43. As shown in Figure 4A, in the state before the engaged portion 43 engages with the engaging portion 12, the projection 46 protrudes from the second hole 44. In the leaf spring, the outer surface extending substantially parallel to the outer surface on which the projection 46 is provided is adhered to the side wall of the engaged portion 43.

[0036] As shown in Figure 4B, when the engaged portion 43 is inserted into the engaging portion 12, the projection 46 abuts against the side wall of the engaging portion 12, pushing the projection 46 from the second hole 44 towards the internal space of the engaged portion 43. In other words, the projection 46 is pushed towards the leaf spring. As the projection 46 is pushed in, the leaf spring deforms so that both ends move closer together. The leaf spring remains deformed so that both ends move closer together until the engaged portion 43 is inserted into the engaging portion 12 at a position where the first hole 26 of the engaging portion 12 and the second hole 44 of the engaged portion 43 overlap.

[0037] As shown in Figure 4C, when the engaged portion 43 is inserted into the engaging portion 12 at a position where the first hole 26 of the engaging portion 12 and the second hole 44 of the engaged portion 43 overlap, the leaf spring presses against the projection 46, causing the projection 46 to protrude from the first hole 26 and the second hole 44. In other words, the engaging portion 12 and the engaged portion 43 engage as the projection 46 penetrates the first hole 26 and the second hole 44.

[0038] On the other hand, when removing the engaged portion 43 from the engaging portion 12, the user first pushes the projection 46 into the internal space, causing the leaf spring to deform so that both ends are brought closer together. With the leaf spring still deformed so that both ends are brought closer together, the user pulls the engaged portion 43 out of the engaging portion 12. Once the engaged portion 43 is pulled out of the engaging portion 12, the leaf spring returns to its roughly U-shaped bend. Also, the leaf spring presses against the projection 46, causing the projection 46 to protrude from the second hole 44.

[0039] [1-2-2. The tip of the sasumata (a type of pole weapon)] As shown in Figure 1C, the tip 5 of the sasumata comprises a pressing portion 51 and an engaging portion 43. The tip 5 of the sasumata is a component manufactured using high-tensile steel with a tensile strength of 780 MPa or higher.

[0040] The pressing portion 51 is a substantially U-shaped member. For example, the pressing portion 51 may have a recessed shape that forms a semicircle. Alternatively, the pressing portion 51 may have a recessed shape that forms an ellipse divided along its major axis, or a recessed shape that forms an ellipse divided along its minor axis. Also, the pressing portion 51 does not have to be curved in a smooth arc, and may have angular parts. Furthermore, the pressing portion 51 may have spikes protruding from it. In short, the pressing portion 51 only needs to have a substantially U-shaped shape overall so that it can hold a moving living organism such as a human being in place.

[0041] The configuration of the engaged portion 43 is the same as that of the engaged portion 43 on the broom head 4 described above. The engaged portion 43 of the tip 5 of the sasumata is connected to the pressing portion 51 from a position spaced apart from both ends of the pressing portion 51, extending in the direction in which the pressing portion 51 is recessed. More specifically, the engaged portion 43 of the tip 5 of the sasumata is located at the position furthest from both ends of the pressing portion 51 and is connected perpendicular to the pressing portion 51. When the engaged portion 43 of the tip 5 of the sasumata is attached to the engaging portion 12, both ends of the pressing portion 51 face in the direction from the second end 22 toward the first end 21.

[0042] [1-3. Effects] According to the embodiments described in detail above, the following effects can be obtained. (1a) An engaging portion 12 is provided at the first end 21 of the rod-shaped portion 11, and a flat portion 13 is provided at the second end 22 of the rod-shaped portion 11. The flat portion 13 includes a flat plate portion 29. With this configuration, for example, a user can insert the flat plate portion 29 into a gap in rubble and lift the rubble using the principle of leverage. Alternatively, for example, a user can insert the flat plate portion 29 into a gap between a door and a wall and pry open the door. In other words, a user can use the crowbar / crowbar tool 1 as a crowbar.

[0043] Furthermore, when the broom head 4 is attached to the engaging part 12, the user can use the crowbar / tool ​​1 as a broom, as shown in Figure 5A. Also, when the tip 5 of the fork is attached to the engaging part 12, the user can use the crowbar / tool ​​1 as a fork, as shown in Figure 6.

[0044] In other words, the crowbar / crowbar combination tool 1 can function as a crowbar while also possessing other functions such as a cleaning tool or a security device. Therefore, the versatility of the crowbar / crowbar combination tool 1 can be increased.

[0045] Furthermore, crowbars and shackles are used in emergencies, while brooms are used on a daily basis. If a crowbar, shackle, and broom were each owned as separate tools, space would be needed to store all three tools. Moreover, crowbars and shackles tend to be stored in a space for items used infrequently, while brooms tend to be stored in a space for items used frequently. In other words, crowbars and shackles tend to be stored in separate spaces from brooms. However, with the configuration described above, for example, if the crowbar / crowbar tool 1 is stored with the broom head 4 attached, the crowbar and broom can be stored in the same space. Also, since the tip 5 of the shackle is part of the shackle, it requires less storage space than storing the entire shackle. Therefore, it becomes easier to store the crowbar / crowbar tool 1, the broom head 4, and the tip 5 of the shackle as a single unit in the same place. By storing not only the broom head 4, but also the crowbar / arm attachment 1 and the tip of the long-handled fork 5 in a place that is easily visible on a daily basis, the effort of searching for their storage location in an emergency can be saved. Furthermore, by storing the crowbar / arm attachment 1 and the tip of the long-handled fork 5 in a place that is easily visible on a daily basis, awareness of disaster prevention and crime prevention can be heightened in everyday life.

[0046] (1b) The flat plate portion 29 has a through hole 33 that penetrates the flat plate portion 29 in a direction perpendicular to the direction in which the flat plate portion 29 protrudes, and in the thickness direction in which the thickness of the flat plate portion 29 is relatively thin. With this configuration, for example, the through hole 33 can be hooked onto a hook or the like. Therefore, as shown in Figure 5B, the crowbar / tool ​​1 can be hung and stored by hooking it onto a hook in a cleaning supplies storage area. Since a crowbar is used for stabbing or in emergencies, it is not used frequently in daily life. However, with the above configuration, the crowbar / tool ​​1 can be easily stored in a familiar place as a tool used on a daily basis, rather than in a warehouse or the like. For example, in the event of a major earthquake or other emergency when an emergency escape is required, the crowbar / tool ​​1 can be easily picked up by the user.

[0047] (1c) The rod-shaped part 11 is a component manufactured using high-tensile steel with a tensile strength of 780 MPa or more. With this configuration, the strength of the rod-shaped part 11 can be increased, and the weight can be reduced. When the crowbar / tool ​​1 is used as a crowbar, its high strength and light weight make it easier to handle. Similarly, when the crowbar / tool ​​1 is used as a long-handled fork, its high strength and light weight make it easier to handle. Furthermore, when the crowbar / tool ​​1 is used as a broom, its light weight makes it easier to handle.

[0048] (1d) The flattened portion 13 is a component manufactured using high-tensile steel with a tensile strength of 780 MPa or more. With this configuration, the strength of the flattened portion 13 can be increased. Therefore, when the crowbar / tool ​​1 is used as a crowbar, chipping or deformation of the flattened portion 13 can be suppressed.

[0049] (1e) The rod-shaped portion 11 is hollow with an internal space, and the second end 22 of the rod-shaped portion 11 is closed. With this configuration, the strength of the second end 22 of the rod-shaped portion 11 can be increased compared to a configuration in which the second end 22 of the rod-shaped portion 11 is open. In particular, when the crowbar / pry bar tool 1 is used as a crowbar, it is possible to suppress the second end 22 of the rod-shaped portion 11 from becoming dented or bent.

[0050] (1f) The projection 46 of the leaf spring penetrates the first hole 26 and the second hole 44, thereby engaging the engaging portion 12 and the engaged portion 43. With this configuration, the engaging portion 12 and the engaged portion 43 can be engaged simply by inserting the engaged portion 43 into the engaging portion 12. Therefore, the broom head 4 or the tip 5 of the sasumata can be quickly attached to the crowbar / crowbar tool 1. In particular, since the sasumata is used in emergencies, it is preferable from a security standpoint that the tip 5 of the sasumata can be quickly attached to the crowbar / crowbar tool 1.

[0051] (1g) The engaging portion 12 comprises a small diameter portion 25 and an enlarged diameter portion 27. With this configuration, even if the diameter of the rod-shaped portion 11 and the diameter of the engaged portion 43 are significantly different and cannot be directly connected, the diameter of the cylinder can be adjusted using the small diameter portion 25 and the enlarged diameter portion 27 to indirectly connect the rod-shaped portion 11 and the engaged portion 43. Therefore, even when attaching an existing broom head 4 or the tip of a sasumata 5 to the crowbar / crowbar tool 1, it can be attached by adjusting the diameters of the small diameter portion 25 and the enlarged diameter portion 27 without changing the diameter of the rod-shaped portion 11 itself. Thus, since existing broom heads 4 and the tips of sasumata 5 can also be attached, the versatility of the crowbar / crowbar tool 1 can be increased.

[0052] (1h) The flat plate portion 29 is chamfered. With this configuration, when a user uses the crowbar / tool ​​1 as a broom or fork, the possibility of injury is reduced even if the user comes into contact with the flat portion 13. Thus, the safety of the crowbar / tool ​​1 can be increased.

[0053] [1-4. Correspondence] In the above embodiment, the tip 5 of the sasumata corresponds to a restraining device. [2. Other Embodiments] While embodiments of this disclosure have been described above, it goes without saying that this disclosure is not limited to the embodiments described above and can take various forms.

[0054] (3a) In the above embodiment, a configuration in which the flattened portion 13 includes a flat plate portion 29 was illustrated. However, the shape of the flattened portion 13 is not limited to this. The flattened portion 13 is a virtual rectangle that surrounds the cross-section of the flattened portion 13 perpendicular to the direction in which the flattened portion 13 protrudes, and when a rectangle is drawn tangent to the outer circumference of the cross-section, the length of the first side, which is one side of the rectangle, and the length of the second side perpendicular to the first side are different. In other words, the rectangle can be a rectangle, and the flattened portion 13 can be a flattened shape.

[0055] Figure 9A shows a hypothetical rectangle 60 that surrounds the cross-section of the flat plate portion 29 of the flat portion 13 perpendicular to the direction in which the flat plate portion 29 protrudes (i.e., upward direction) (i.e., the cross-section that extends in the front-to-back direction and the left-to-right direction), and the rectangle 60 is tangent to the outer circumference of the said cross-section. Both the outer circumference of the said cross-section and the rectangle 60 have a rectangular shape in which the length of the first side W and the length of the second side H are different.

[0056] For example, the flat plate portion 29 may have a shape in which the thickness decreases towards the tip, or a shape in which the width decreases towards the tip. Also, the direction in which the flattened portion 13 protrudes is not limited to the direction from the first end portion 21 to the second end portion 22 (in other words, upward). The flattened portion 13 may be partially curved or bent. In other words, the direction in which the flattened portion 13 protrudes can also be said to be the direction in which the tip of the flattened portion 13 points. The flattened portion 13 may partially protrude in the front-rear direction and / or the left-right direction. As shown in Figure 9B, for example, the flattened portion 13 may include a bent member 61 having an L-shaped bend. Also, the tip of the bent member 61 may be flat and bifurcated. In the flattened portion 13 equipped with the bent member 61, the direction indicated by arrow A is the direction in which the flattened portion 13 protrudes.

[0057] Figure 9C shows a hypothetical rectangle 62 surrounding the cross-section of the bent member 61 of the flattened portion 13 (i.e., the cross-section that extends in the front-to-back and up-and-down directions) perpendicular to the direction in which the bent member 61 of the flattened portion 13 protrudes (i.e., to the left), and the rectangle 62 is tangent to the outer circumference of the said cross-section. The outer circumference of the said cross-section has a substantially elliptical shape. The rectangle 62 tangent to the substantially elliptical outer circumference has a rectangular shape in which the length of the first side W and the length of the second side H are different. Even with this configuration, because the tip of the flattened portion 13 is flattened, it is easy to insert the tip of the flattened portion 13 into gaps in rubble, etc., and the crowbar / tool ​​1 can be used as a crowbar. Also, if the flattened portion 13 is provided with a through hole 33, it can be hooked onto a hook, etc., regardless of the shape of the flattened portion 13.

[0058] (3b) In the above embodiment, a configuration in which the rod-shaped portion 11 is hollow with an internal space was illustrated. However, the shape of the rod-shaped portion 11 is not limited to this. For example, the rod-shaped portion 11 may be solid with no internal space. That is, the rod-shaped portion 11 may be cylindrical. Also, for example, the rod-shaped portion 11 may be rectangular tube-shaped or rectangular prism-shaped.

[0059] (3c) In the above embodiment, a configuration in which the engaged portion 43 is inserted into the engaging portion 12 was illustrated. However, the engaging portion 12 may be inserted into the engaged portion 43. In other words, the diameter of the engaged portion 43 may be slightly larger than the diameter of the engaging portion 12. The elastic member 45 may be arranged in the internal space of the engaging portion 12.

[0060] (3d) In the above embodiment, an example was given in which the engaging portion 12 and the engaged portion 43 engage by the projection 46 of the elastic member 45 passing through the first hole 26 and the second hole 44. However, the configuration in which the engaging portion 12 and the engaged portion 43 engage is not limited to this. For example, the small diameter portion 25 may have a first hole 26 that penetrates from side wall to side wall of the small diameter portion 25 in a direction perpendicular to the direction in which the small diameter portion 25 extends. In other words, two first holes 26 may be provided at opposing positions on opposing side walls of the small diameter portion 25. As shown in the modified example 1 of Figures 7A and 7B, the broom head 4 and the tip 5 of the sasumata, the engaged portion 43 may have a second hole 44 that penetrates from side wall to side wall of the engaged portion 43 in a direction perpendicular to the direction in which the engaged portion 43 extends. In other words, the opposing side walls of the engaging portion 12 may have two second holes 44 at opposing positions. The engaging portion 12 and the engaged portion 43 may be engaged by inserting a bolt through the first hole 26 and the second hole 44 and engaging it with a nut.

[0061] (3e) In the above embodiment, a configuration in which the rod-shaped portion 11 and the flat portion 13 are separate parts was illustrated. However, the rod-shaped portion 11 and the flat portion 13 may be integrally formed. For example, as shown in Modification 2 of Figure 8, the flat portion 13 may be formed into a plate shape by pressing the second end 22 of the rod-shaped portion 11.

[0062] (3f) The rod-shaped portion 11 may be retractable. As shown in Figure 6, for example, the rod-shaped portion 11 may comprise a first cylindrical portion 35 and a second cylindrical portion 36. The first cylindrical portion 35 and the second cylindrical portion 36 may be tubular with different diameters. For example, the lower part of the first cylindrical portion 35 and the upper part of the second cylindrical portion 36 may be arranged to overlap, and the rod-shaped portion may be retractable by changing the length of the overlapping portion. In other words, the length of the rod-shaped portion 11 may be switched by changing the length of the overlapping portion.

[0063] Furthermore, the first cylindrical portion 35 and the second cylindrical portion 36 may also be configured to include a first hole portion 26 and a second hole portion 44, an elastic member 45 and a projection 46, similar to the engaging portion 12 and the engaged portion 43. With such a configuration, the length of the rod-shaped portion 11 can be quickly switched. In addition, since the projection 46 penetrates the first hole portion 26 and the second hole portion 44, it is possible to prevent the rod-shaped portion 11 from retracting unintentionally.

[0064] (3g) In the above embodiment, the object is shown to be the head 4 of a broom and the tip 5 of a sasumata. However, the type of object is not limited to this. For example, the object may be the head of a mop or a cleaning wiper.

[0065] (3h) The functions of one component in the above embodiment may be distributed among multiple components, or the functions of multiple components may be integrated into one component. Also, some parts of the configuration of the above embodiment may be omitted. Also, at least some parts of the configuration of the above embodiment may be added to, replaced with, etc., the configuration of other above embodiments. [Explanation of Symbols]
