Description

[Technical Field]

[0001] The present invention relates to a clip that can be attached to a suspension bolt or the like and can support a sheet or the like in the attached state, and more particularly to a clip that can be attached to a suspension bolt or the like using a manipulator. [Background technology]

[0002] In buildings, train stations, etc., when a leak occurs in a section of the ceiling, a simple emergency measure is to cover the leaking part of the ceiling with a protective sheet. For example, by creating a water inlet in the center of the protective sheet and connecting a hose or drain pipe to the water inlet, the leaked water can be discharged into a bucket or outside (see Patent Documents 1 and 2).

[0003] On the other hand, a leaking water tray can be installed using hanging bolts placed in the ceiling of a building, etc. (see Patent Document 3). Also, a liquid receiving sheet can be installed on the hanging bolts by preparing multiple strip-shaped sheets of a size that matches the placement of the hanging bolts and connecting them together with fasteners (see Patent Document 4). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6382469 [Patent Document 2] Japanese Utility Model Application Publication No. 4-94045 [Patent Document 3] Japanese Patent Application Publication No. 52-25416 [Patent Document 4] Patent Publication No. 2021-92084 Summary of the Invention [Problem to be solved by the invention]

[0005] The ceilings of stations and other buildings are often filled with pipes, power lines, and communication cables, as well as related equipment. This leaves insufficient space for work. Meanwhile, when installing a sheet to cover a water leak, if the suspension bolts needed to install the sheet are far from the ceiling inspection hatch, it can be virtually impossible to carry out the installation work. The same problem arises when installing a sheet in a location where a stepladder or similar equipment cannot be installed, or where it is difficult to reach.

[0006] Therefore, there is a need to provide a tool that can be easily attached to a hanging bolt or the like that is difficult to access and that can hold a seat or the like. [Means for solving the problem]

[0007] The present invention addresses the technical trend of providing a clip that can be attached to a hanging bolt or the like by utilizing a remotely operated manipulator and that can hold a sheet or the like.

[0008] The clip of the present invention is a clip that can fasten to a suspension bolt an object that can be held (herein referred to as a workpiece), such as a sheet such as a liquid receiving sheet (including a protective sheet) or a hanger that holds a base material, and is configured so that it can be attached to the suspension bolt by remote control using a manipulator. The manipulator only needs to be able to perform movements similar to those of a human hand, and can be configured as a manipulator that can at least perform the actions of grasping and releasing the grasped object by remote control.

[0009] The clip of the present invention is provided with a clamping member provided with a spring, and a pair of pieces that can open and close around the connecting part as an axis. For example, a coiled torsion spring can be arranged coaxially with the connecting part. The width and length of the pair of pieces can be determined based on the size (diameter) of the hanging bolt, etc. The elastic force of the spring can be determined, for example, so that the clip can slide when a force is applied in the longitudinal direction of the clamping member while the hanging bolt is clamped by the clamping member.

[0010] In the present invention, one of the clamping members has a curved portion extending away from the other member so that the manipulator can grasp the other member, and also has an engagement portion for connecting directly or indirectly with the workpiece.

[0011] The configuration of the warped portion, such as the degree of expansion and inclination angle relative to the other piece, can be determined depending on the size and shape of the tip of the manipulator (the gripping portion and the portion extending from the gripping portion toward the operator (e.g., the bay-shaped portion)). The configuration of the engaging portion can be determined according to the type of material to be attached, such as a sheet, and the intervening material used for connecting the material. For example, if the liquid receiving sheet is to be hung using a hanging bolt, a hole for passing a string or the like can be configured as the engaging portion.

[0012] In the present invention, the spring applies force to close the sides of the pair of pieces where the curved portion and the engaging portion are formed, and the clamping member can clamp the suspension bolt between the curved portion and the connecting portion, thereby attaching the clip to the suspension bolt.

[0013] Convex portions facing each other can be formed between the curved portion and the connecting portion of each pair of pieces. The size and shape of the convex portions can vary, as long as they are determined so that the clip can slide over the hanging bolt while being clamped by the clamping member. For example, they can be configured as mountain-shaped convex portions. In this context, the term "convex portion" also includes stepped shapes. The clamping member can be configured to clamp the hanging bolt between the convex portions and the connecting portion.

[0014] The pair of pieces may be configured to be in contact with or close to each other, for example, one end of the warped portion may be configured to be in contact with the other piece.

[0015] The clamping member may be configured so that its attachment position relative to the suspension bolt is determined by the elastic force of a spring, or so that it engages with the threads of the suspension bolt and is positioned vertically. To prevent the clip from changing position due to the weight of the attached material, such as a sheet, pulling it downward, the pair of pieces may be provided with edges that can engage with the male threads of the suspension bolt. For example, both longitudinal edges of the pair of pieces may be formed into edge-like edges that protrude from the pieces. Alternatively, only one edge may be formed into an edge-like edge.

[0016] By using the clip of the present invention described above, a method for hanging a liquid receiving sheet from a hanging bolt placed in the ceiling can be provided. In another aspect of the present invention, a method for hanging a liquid receiving sheet involves connecting the liquid receiving sheet directly or indirectly to the engaging portion of the clip, clamping the other piece of the clip with the tip of a manipulator, and attaching the clip to the hanging bolt by pulling the manipulator from the back side of the hanging bolt toward the front side as seen from the manipulator operator so that the hanging bolt passes between the pair of pieces. The liquid receiving sheet here includes a curing sheet. For example, the liquid receiving sheet can be hung by threading a string through multiple holes in the corners of the liquid receiving sheet and attaching clips to hanging bolts located in suitable positions for hanging from the positions of each hole. Furthermore, the term "rear side" here does not refer only to the point strictly opposite the suspension bolt, but also includes the range beyond the suspension bolt as viewed from the operator's side (the space further away from the imaginary plane perpendicular to the operator that passes through the suspension bolt), and is defined as the range within which the manipulator can perform clip attachment operations.

[0017] Furthermore, by using the clip of the present invention described above, a method for attaching other workpieces to rod-shaped members other than suspension bolts can be provided. In another aspect of the present invention, the method for attaching a workpiece to a rod-shaped member involves connecting the workpiece directly or indirectly to the engaging portion of the clip, clamping the other piece of the clip with the tip of a manipulator, and attaching the clip to the rod-shaped member by pulling the manipulator from the rear side of the rod-shaped member toward the front side as seen from the manipulator operator so that the rod-shaped member passes between the pair of pieces. The meaning of "rear side" here is as described above.

[0018] Another aspect of the present invention is a clip that includes an elastic clamping member capable of clamping a rod-shaped member, one end of which expands so that it can be grasped by a manipulator. An engaging portion for directly or indirectly connecting the clamping member to the workpiece is formed on the one end of the expanding clamping member, allowing the rod-shaped member to be slidably clamped from the one end of the expanding clamping member to the attachment position. The clamping member can be configured, for example, so that a pair of pieces are opened and closed by a spring. Various springs, such as torsion springs and C-shaped springs, can be used. The clamping member can also be opened and closed by an elastic member or material other than a spring. Alternatively, the clamping member can be formed by bending a plate-shaped member to clamp a rod-shaped member, such as a hanging bolt. The shape and degree of expansion of the clamping member can be determined according to the shape (e.g., curved shape) and shape (e.g., curved and straight portions or curved portion only) of the tip of the manipulator, i.e., the part that grips the workpiece. [Effects of the Invention]

[0019] According to the present invention, it is possible to provide a clip that can be easily attached to a hanging bolt or the like that is difficult to access and that can hold a sheet or the like. [Brief explanation of the drawings]

[Figure 3] FIG. 2 is a schematic cross-sectional view taken along the line II-II of FIG. [Figure 4] FIG. 2 is a schematic plan view showing a part of the clip of the present embodiment. [Figure 5] 10A and 10B are diagrams showing the process of attaching a clip to a hanging bolt using a manipulator. DETAILED DESCRIPTION OF THE INVENTION

[0021] Hereinafter, the clip according to this embodiment and a method for attaching (hanging) the liquid receiving sheet to the hanging bolt will be described with reference to the drawings.

[0022] The liquid receiving sheet 100 is configured as a sheet that can receive water leaking from rainwater and the like above the ceiling and extract the leaked water so that it does not reach the ceiling. Here, the liquid receiving sheet 100 is installed in the above-the-ceiling space of a building such as a station building.

[0023] The liquid receiving sheet 100 is made of a stretchable sheet, such as a lightweight, waterproof polyester sheet (e.g., a white smokeproof sheet). The liquid receiving sheet 100 may also be made of a transparent vinyl sheet, or a conventional protective sheet may be used.

[0024] A metal fitting 130 having an opening that serves as a drain outlet is attached near the center of the liquid receiving sheet 100, and the tip of the hose 120 is connected to the metal fitting 130. Leaked water that drips onto the liquid receiving sheet 100 flows down the surface of the sheet toward the drain fitting 130 and into the hose 120 to be extracted.

[0025] A plurality of holes are formed around the periphery of the liquid receiving sheet 100. Here, holes 100R are formed at the four corners of the liquid receiving sheet 100 and near the edge in between. A string 150 for hanging the liquid receiving sheet 100 is threaded through each hole 100R. Note that Fig. 1 shows only a portion of the liquid receiving sheet 100, and only one hole 100R is shown.

[0026] In the attic space, the underlayment materials, the rafter support materials (not shown), are installed in a row on the underside of the ceiling, and the rafters (not shown) are installed in a direction that crosses the rafter support. The hanging bolts 200 that hang down from the base above are connected to the rafters via hanging hangers (not shown). The hanging bolts 200 are lined up in line with the installation locations of the rafters, and are regularly spaced at predetermined intervals along the direction in which the rafters extend.

[0027] The clip 10 is a fastener for attaching and supporting (hanging) the liquid receiving sheet 100 to the hanging bolt 200, and by clamping the hanging bolt 200, it is possible to hold the liquid receiving sheet 100 in a state where it is attached to the hanging bolt 200.

[0028] The liquid receiving sheet 100 is attached to and hung from a plurality of hanging bolts 200 that hang down at positions relatively close to holes 100R formed in the four corners and the central edge portion. Clips 10 connected to strings 150 passed through each hole 100R are attached at a predetermined height to the corresponding hanging bolts 200. The liquid receiving sheet 100 is held in a bent state with the center portion at a low position.

[0029] Fig. 2 is a schematic side view of the clip. Fig. 3 is a schematic cross-sectional view taken along line II-II in Fig. 2. Fig. 4 is a schematic plan view showing a portion of the clip as viewed from above. The configuration of clip 10 will be described with reference to Figs. 2 to 4.

[0030] As shown in FIG. 2, clip 10 includes a clamping member 15 made up of a pair of pieces 20, 30. Piece (one piece) 20 is made of a plate material bent midway, and piece (the other piece) 30 is made of a straight plate material. When viewed from the side with the pair of ends 20E2, 30E2 facing downwards, clip 10 has a K-shaped form. The pair of pieces 20, 30 may be made of any material, such as a metal such as stainless steel. Each of pieces 20, 30 may be formed by joining multiple plates together.

[0031] The clamping member 15 includes a spring 40. As shown in Fig. 3, the spring 40 is a coiled torsion spring and is disposed at a connecting portion 50 of the pair of pieces 20, 30. The connecting portion 50 has a structure in which tongue portions 22, 32 formed on both edges along the longitudinal direction of the pair of pieces 20, 30 are in surface contact with each other. The spring 40 is disposed between the tongue portions 22, 32 of the connecting portion 50 so that its coil axis is aligned along the short direction of the pair of pieces 20, 30.

[0032] The spring 40 exerts an elastic force in a direction in which the ends 20E1, 30E1 (hereinafter referred to as one end) of the pair of pieces 20, 30 open, i.e., in a direction in which the ends 20E2, 30E2 (hereinafter referred to as the other end) close. Therefore, when a force is applied in a direction in which the other ends 20E2, 30E2 of the pair of pieces 20, 30 approach each other, a restoring force acts. Note that the spring 40 can also be formed using an elastic member other than a torsion spring.

[0033] The clamping member 15 is configured to be axially rotatable around the axis C of the connecting portion 50. For example, a pin (not shown) can be passed through a hole 50R formed around the axis C, and the pair of pieces 20, 30 can be rotated about the axis while in surface contact at the connecting portion 50. Alternatively, by abutting both ends of the spring 40, which is a torsion spring, against the edges of the pair of pieces 20, 30 and applying a force, the pair of pieces 20, 30 can be rotated about the axis while in surface contact at the connecting portion 50.

[0034] When the clamping member 15 is closed, the bent piece 20 comes into contact with the piece 30 midway. A warped portion 21 is formed extending away from the piece 30 beyond the contact point CT with the piece 30. A distance is provided between the warped portion 21 and the piece 30 so that the tip of a manipulator (described later) can grasp the piece 30. Here, the warped portion 21 extends at a certain inclination angle relative to the piece 30.

[0035] A hole 21R is formed on one end 20E1 side of the piece 20 (see FIG. 4). The hole 21R is configured as an engagement portion that connects the string 150 to the clip 10. Here, the end of the string 150 shown in FIG. 1 is attached to a double ring RR, and the double ring RR is attached to the hole 21R. Alternatively, the string 150 may be tied directly to the hole 21R.

[0036] Restricting members 25, 35 are attached to the pair of pieces 20, 30, respectively. Here, the restricting member 25 is composed of a screw 26, a washer 27, and a nut 28. Similarly, the restricting member 35 is composed of a screw 26, a washer 27, and a nut 28. The tips 26T, 36T of the screws 26, 36 form convex portions on the surfaces 20S, 30S of the pieces 20, 30 that face each other. When the pair of pieces 20, 30 are closed, the tips 26T, 36T of the screws 26, 36 are in contact with each other.

[0037] The pair of pieces 20, 30 have oblong holes 20R, 30R formed along the longitudinal direction (see FIGS. 2 and 3). The restricting members 25, 35 are attached to the pieces 20, 30, respectively, through these holes 20R, 30R. The restricting members 25, 35 can be fixed within the opening areas along the longitudinal direction of the holes 20R, 30R, and the attachment positions of the restricting members 25, 35 can be adjusted along the longitudinal direction.

[0038] As shown in Fig. 3, the pair of pieces 20, 30 have edge-like edge portions 20G, 30G that extend perpendicularly from the surfaces 20S, 30S. However, in Fig. 3, the thickness of the pair of pieces 20, 30 and the thickness of the connecting portion 50 are exaggerated.

[0039] Using the clip 10 equipped with such a pinching function, a worker can install the liquid receiving sheet 100 above the ceiling. Specifically, the worker remotely attaches the clip 10, which is connected to the liquid receiving sheet 100 via the string 150, to a predetermined hanging bolt 200. This will be described below.

[0040] FIG. 5 is a diagram showing the process of attaching the clip 10 to the suspension bolt 200 using a manipulator.

[0041] Here, the manipulator 300 is configured by an operating tool known as a magic hand. The manipulator 300 is provided with a gripper 300I at the tip of a rod-shaped member (not shown) that is extendable and can be stretched to a length of several meters. An operating unit (not shown) that is operated by an operator is provided at the opposite end of the rod-shaped member. The gripper 300I opens and closes in response to an opening and closing operation by the operator. Note that the mechanism by which the gripper 300I opens and closes in response to an operation on the operating unit of the manipulator 300 is well known technology, and therefore a description thereof will be omitted here.

[0042] The size of the space RS (see FIG. 2) formed between the warped portion 21 and the piece 30, i.e., the degree to which the warped portion 21 is warped from the piece 30, is set to a size that allows the tip 300R of the manipulator 300 to be opened and the vicinity of one end 30E1 of the piece 30 to be grasped. Here, the inclination angle of the warped portion 21 relative to the piece 30 is set to an angle that allows the tip 300R to be opened and closed.

[0043] First, the worker (operator) attaches the string 150 to the hole 100R of the liquid receiving sheet 100 and ties the string 150 to the double ring RR. Then, the double ring RR is attached to the hole 21R formed in the warped portion 21 of the piece 20. However, the double ring RR and the string 150 are not shown in FIG. 5.

[0044] Next, the worker carries the liquid receiving sheet 100 connected to the clips 10 into the ceiling space through a ceiling inspection hatch or the like. The worker grasps the vicinity of one end 30E1 of the piece 30 of the clip 10 with the tip 300R of the manipulator 300 and stretches the rod-shaped member of the manipulator 300. The worker then extends the manipulator 300 toward the target suspension bolt 200.

[0045] Here, the worker attaches the clip 10 to the suspension bolt 200 by pulling the manipulator 300 from the back side of the suspension bolt 200 toward the front side as seen from the worker. In order to clamp the suspension bolt 200 while sliding it from one end 20E1, 30E1 side of the pair of pieces 20, 30, the clip 10 is moved to the back side of the suspension bolt 200, and then the manipulator 300 is pulled from there.

[0046] 2, the position of the suspension bolt 200 when the clip 10 is located further back than the suspension bolt 200 as seen from the operator is indicated by the symbol F1. By pulling the manipulator 300 in, the clamping member 15 comes into contact with the suspension bolt 200 and opens. Then, the manipulator 300 is pulled back past the contact point CT with the piece 30 of the warped portion 21, climbs over the restricting member 25, and reaches a position where it comes into contact with the connecting portion 50. FIG. 5 shows the state in which the suspension bolt 200 climbs over the restricting member 25.

[0047] 2 shows the hanging bolt 200 with the clips 10 attached. The clamping member 15 clamps the hanging bolt 200 while it is housed between the restricting members 25, 35 and the connecting portion 50. The restoring force of the spring 40 firmly fixes and positions the clips 10 to the hanging bolt 200. The installation work of the liquid receiving sheet 100 is completed when the worker attaches all of the clips 10 to the target hanging bolts 200 at the predetermined positions (heights).

[0048] On the other hand, when removing or reinstalling the liquid receiving sheet 100, the worker uses the manipulator 300 to grasp the piece 30 of the clip 10 attached to the suspension bolt 200. Then, the worker pushes the manipulator 300 toward the back side of the suspension bolt. This opens the clamping member 15, and the clip 10 is removed from the suspension bolt 200.

[0049] As described above, according to this embodiment, the clip 10 for supporting the liquid receiving sheet 100 with the hanging bolt 200 includes a clamping member 15 composed of a pair of pieces 20, 30, and is configured to be openable and closable around the axis of the connecting part 50 by a spring 40. One of the pieces 20 is formed with a warped part 21 so that the piece 30 can be grasped by the tip 300R of the manipulator 300. The warped part 21 is also formed with a hole 21R for connecting the string 150 tied to the liquid receiving sheet 100.

[0050] The ceiling of a building or other structure has limited space due to the installation of power lines, communication lines, water supply and sewage pipes, air conditioning pipes, and related equipment, resulting in a small work area. Furthermore, the location of the suspension bolt 200 to be attached may be far from the ceiling inspection hatch. However, because the clip 10 is attached to the suspension bolt 200 using the manipulator 300, the liquid receiving sheet 100 can be easily installed in the ceiling.

[0051] In particular, the formation of the warped portion 21 on the piece 20 makes it easy to grasp and hold the piece 30 even when using a manipulator 300 having a tip 300R with a curved portion or the like. Furthermore, by grasping the rearward side (the connecting portion 50 side) of the piece 30 from the vicinity of the end 30E1, the clip 10 can be stably held when attaching it to the suspension bolt 200. For example, FIG. 2 shows a state in which the end 30E1 of the piece 30 is grasped by the parallel portions of the tip 300R that contact the piece 30, but it is also possible to grasp a portion near the restricting members 25, 35. This is because the warped portion 21 widens the distance between the pair of pieces 20, 30, creating space to accommodate the curved portion formed on the tip 300R (extending from the grasping portion toward the operator). This allows the clip 10 to be held more stably.

[0052] The shape of the tip 300R of the gripping part 300I of the manipulator 300 may be other than that shown in Fig. 5. For example, there are manipulators that do not have the shape of the tip 300R of the gripping part 300I of the manipulator 300 (i.e., the shape of the tip 300R of the gripping part 300I of the manipulator 300, which does not have parallel gripping parts as shown in Fig. 5) and have a tip that is composed only of a curved part. The shape and formation position of the warped part 21 relative to the piece 20, such as the position and inclination angle of the contact part CT of the warped part 21 with the piece 20, may be determined according to the shape of the tip 300R of the manipulator 300, etc.

[0053] Furthermore, because the clip 10 is attached to the hanging bolt 200 by pulling the manipulator 300 from the rear side of the hanging bolt, it is resistant to tensile forces toward the sheet side and serves as a stable fixing point for the liquid receiving sheet 100. That is, the weight of the liquid receiving sheet 100 acts to pull the piece 20 of the clip 10 toward the sheet side, but the connecting portion 50 of the clip 10 abuts against the hanging bolt 200 and is sandwiched between the protrusions (restricting members 25, 35) and the connecting portion 50, so that the liquid receiving sheet 100 can be stably supported.

[0054] On the other hand, when removing the clip 10 from the suspension bolt 200, the manipulator 300 is pushed toward the back of the suspension bolt, making it easy to remove the clip 10. Since there is strong resistance to pulling force toward the operator and weak resistance in the direction of pushing the manipulator 300, the attachment position of the clip 10 to the suspension bolt 200 can be easily adjusted.

[0055] In the clip 10 of this embodiment, the restricting members 25, 35 form convex portions on the surfaces 20S, 30S of the pair of pieces 20, 30. This restricts the relative movement of the clip 10 with the suspension bolt 100 clamped against the convex portions, thereby enabling the clip 10 to stably maintain a state in which it firmly clamps the suspension bolt 200. Note that it is also possible to provide a step as a convex portion on the surfaces 20S, 30S of the pair of pieces 20, 30 to the extent that the clip 10 can be removed, and a configuration may be adopted in which the relative movement of the clip 10 is restricted.

[0056] Furthermore, since the positions of the regulating members 25, 35 are adjustable along the longitudinal direction of the pair of pieces 20, 30, the positions of the regulating members 25, 35, i.e., the positions of the convex portions, can be determined according to the size (diameter) of the hanging bolt 200, etc.

[0057] Edge-like edges 20G, 30G are formed along the longitudinal direction of the pair of pieces 20, 30, respectively. These edges 20G, 30G engage with threaded portions (external threads) formed on the surface of the suspension bolt 200. This prevents the clip 10 from shifting up and down (vertical direction) while clamping the suspension bolt 200, and enables the clip 10 to be more firmly positioned relative to the suspension bolt 200. Note that the edge-like edges 20G, 30G may be formed on only one edge of the pieces 20, 30, rather than on both edges along the longitudinal direction.

[0058] The clamping member 15 of the clip 10 is not limited to being formed by a pair of pieces 20, 30, but may also be formed by folding a plate-like member to form an elastic body. Furthermore, the clip 10 may be configured to hold a member other than the liquid receiving sheet 100, such as a base material hanging hanger.

[0059] In this embodiment, the clip 10 is configured to be attachable to the hanging bolt 200 above the ceiling, but even when a protective sheet is to be attached to the ceiling surface, a rod-shaped member attached to the ceiling surface or a rod-shaped member attached to the ceiling surface can be used to support the protective sheet with the clip 10. Alternatively, when installing an emergency fall prevention net, the clip can be used to install the net in a location that is out of reach of a stepladder or the like.

[0060] Furthermore, the clip 10 can also be used for purposes other than buildings. For example, the clip 10 can be used to hang a vinyl tent roof, hammock, or the like on a rack when outdoors or camping. [Explanation of symbols]
