Description

Technical Field

[0001] The present invention relates to a hanging tool. More specifically, the present invention relates to a hanging tool capable of transporting or storing a plurality of members including a bolt having a bolt head or a nut screwed onto a bolt shaft in a suspended state using the bolt head or the nut. Background Art

[0002] Temporary scaffolds used for constructing buildings such as houses and buildings have been conventionally known. This temporary scaffold is necessary for construction personnel involved in construction to efficiently and safely proceed with construction. In order to partition the work space for construction personnel, pipe bodies and the like are assembled along the outer wall of a building structure using clamp members. Pipe bodies, clamp members, and the like constituting a temporary scaffold are carried in and out for each construction site, and efficient transportation, storage, and inspection thereof are required. In particular, while clamp members are smaller than pipe bodies, they are used in large quantities and have irregular shapes, so it is not easy to transport or store them in an organized state. Summary of the Invention Problem to be Solved by the Invention

[0003] When construction of a house or building is completed, such a temporary scaffold is disassembled, transported to a new construction site, and re-assembled at that construction site. However, the number of members constituting the temporary scaffold is extremely large, and improvement of workability during transportation has been desired. For example, as shown in Figure 9, a clamp member connecting pipes has a fixed jaw 101 detachably attached to one end of a pipe 100, to which a rotating jaw 102 is pivotally connected. The two jaws 101 and 102 hold the outer surface of another pipe 103 in the temporary scaffolding, and the clamp members are fastened together by fastening means 104 consisting of bolts and nuts. When the temporary scaffolding is dismantled, such clamp members are removed from the pipes and placed in storage bags in multiples. Workers then load these storage bags onto the bed of a transport truck or the like. However, the number of storage bags containing multiple clamp members is enormous, and the task of workers manually loading each one onto the bed of a transport truck or the like is extremely time-consuming and causes significant fatigue.

[0004] Furthermore, there was a problem in that workers sometimes accidentally dropped the storage bag containing the clamp components while carrying it, which could cause damage to the clamp components. In addition, if multiple clamp components were stored haphazardly in the storage bag, the clamp components could become entangled with each other, or the bolts, nuts, or jaws of the clamp components could collide with each other, which could make it time-consuming to remove the clamp components from the storage bag, or could cause scratches, deformation, or damage to the clamp components.

[0005] Furthermore, while temporary scaffolding is generally rented or leased, companies that rent out temporary scaffolding store unused parts in warehouses, for example. The clamp components mentioned above are often stored in stacks, still in their storage bags. Although rental companies periodically inspect the clamp components, this inspection process involves removing each storage bag from the stack and inspecting each clamp component inside, resulting in poor work efficiency. Additionally, when the clamp components are stored in bags, it is impossible to check the quantity, type, or external condition of the clamp components without opening the bags. This has led to problems with the time and effort required for inventory management, sorting, and inspection of the clamp components.

[0006] This invention was made to solve these problems and aims to provide a suspension device that can be efficiently transported or stored. [Means for solving the problem]

[0007] The above objective of the present invention is achieved by a suspension device for suspending a member to which a bolt having a bolt head is connected, or a member to which a bolt with a nut screwed onto the bolt shaft is connected, the suspension device comprising a pair of elongated rail sections arranged at a predetermined interval, and a connecting section that connects one end of each rail section to the other, the rail section having a rail groove formed therein that receives the bolt head or nut of the member and allows the member to slide from one end to the other of each rail section, and the other end of each rail section is provided with a stopper to prevent the member from falling.

[0008] Furthermore, it is preferable that the spacing between each of the rail sections is greater than the width of the fork tines of the forklift.

[0009] Furthermore, each rail section comprises a front wall, a rear wall, an outer side wall, and an inner side wall, and is formed in a rectangular frame shape in a cross-sectional view perpendicular to the longitudinal direction. Preferably, the outer side wall has a pair of rail pieces at the front and rear, spaced apart along its longitudinal direction so that a bolt shaft can be inserted through them.

[0010] Furthermore, it is preferable that each of the rail sections be arranged parallel to one another.

[0011] Furthermore, it is preferable that the openings of each rail groove formed in the pair of rail sections are arranged to face in opposite directions.

[0012] Furthermore, it is preferable that a space is formed between the pair of rail sections into which the fork tines of a forklift can be inserted, and that the connecting section is configured to rest on the upper surface of the fork tines inserted into the space.

[0013] Furthermore, it is preferable that the connecting portion is formed in a rod shape and is slidably mounted on the upper surface of the fork tine along the longitudinal direction of the fork tine.

[0014] Furthermore, it is preferable to further provide reinforcing parts that connect the other ends of each of the rail sections.

[0015] Furthermore, it is preferable that the reinforcing portion is formed in a rod shape, and that each end of the reinforcing portion is positioned within the rail groove of the rail portion and functions as a stopper.

[0016] Furthermore, it is preferable that the distance between the pair of rail pieces is greater than the outer diameter of the bolt shaft of the bolt on the member, and smaller than the minimum width of the bolt head or the nut. [Effects of the Invention]

[0017] According to this invention, a suspension device can be provided that allows multiple members to be suspended from a rail using bolt heads or nuts, and that enables efficient transport or storage of the multiple members. [Brief explanation of the drawing]

MODE FOR CARRYING OUT THE INVENTION

[0019] Hereinafter, the hanging device 1 according to the present invention will be described with reference to the accompanying drawings. Each drawing is partially enlarged or reduced to facilitate understanding of the configuration. Fig. 1 is a schematic configuration front view of the hanging device 1 according to the present invention, and Fig. 2 is a schematic configuration side view as seen from the direction of arrow A in Fig. 1. Further, Fig. 3 is a schematic configuration plan view as seen from the direction of arrow B in Fig. 1, and Fig. 4 is a schematic configuration bottom view as seen from the direction of arrow C in Fig. 1. The hanging device 1 according to the present invention is a device for hanging a member Z to which a bolt having a bolt head is coupled, or a member Z to which a bolt with a nut screwed onto a bolt shaft is coupled. Here, the "member to which a bolt is coupled" includes not only those where the bolt is directly attached to the member Z, but also those where the bolt is indirectly coupled via another member or a fastening member. Further, the "member to which a bolt with a nut screwed thereon is coupled" includes not only those where the fastening position of the nut relative to the bolt is fixed, but also those where the fastening position of the nut can be changed.

[0020] As shown in Figures 1 to 4, this hanging fixture 1 includes a pair of elongated rail portions 2 arranged at a predetermined interval, a connecting portion 3, rail grooves 4, and stoppers 5. Each of the rail portions 2, 2 and the connecting portion 3 is formed of a metal material. However, the material constituting each of the rail portions 2, 2 and the connecting portion 3 is not particularly limited as long as it has strength capable of supporting the load of the suspended member Z, and a metal material, a resin material, a fiber-reinforced resin material, or a material combining these can be used. The interval dimension between the rail portions 2, 2 is preferably set to a dimension larger than the width dimension of the fork tine of a forklift. A space portion into which the fork tine of the forklift can be inserted is formed between the rail portions 2, 2. The space portion is formed to have a width dimension allowing insertion of at least one fork tine.

[0021] Further, the respective rail portions 2, 2 are arranged so as to be parallel to each other. Instead of the configuration in which the rail portions are parallel to each other, the respective rail portions 2, 2 may be configured such that the distance between the respective rail portions 2, 2 increases from the side where the connecting portion 3 is arranged toward the lower end side of the respective rail portions 2, 2, or alternatively, a configuration in which the distance between the rail portions decreases toward the lower end side may be employed. When the respective rail portions 2, 2 are configured to be spaced apart from each other toward the lower end side, interference between the members Z suspended on the respective rail portions 2, 2 can be easily suppressed. On the other hand, when the respective rail portions 2, 2 are configured to approach each other toward the lower end side, the width dimension of the lower portion of the hanging fixture 1 can be reduced, and the space occupied during storage can be reduced.

[0022] The connecting section 3 is composed of a rod-shaped member, and both ends are connected to the upper end of one end of each rail section 2,2. The connecting section 3 and each rail section 2,2 are firmly connected to each other, for example, by welding. The connecting section 3 functions as a supported part that rests on the upper surface of the fork claw inserted between the pair of rail sections 2,2. The connecting section 3 also functions as a handle for the worker to grip when carrying the suspension device 1. The cross-sectional shape of the connecting section 3 is not particularly limited and can be any shape such as circular, elliptical, polygonal, or rectangular. The connecting section 3 can also be formed in a solid or cylindrical shape. Furthermore, by forming the contact surface of the connecting section 3 with the fork claw or the rod-shaped member of the storage shelf described later to be smooth, the suspension device 1 can slide smoothly along the fork claw or the rod-shaped member.

[0023] The rail groove 4 is formed in each rail section 2,2 and is a groove for receiving the bolt head of a member Z to which a bolt having a bolt head is connected, or the nut of a member Z to which a bolt with a nut screwed onto the bolt shaft is connected, and for sliding the member Z from the upper end, which is one end of each rail section 2,2 to the lower end, which is the other end. In the suspension device 1 shown in Figures 1 to 4, each rail section 2,2 is provided with a front wall 21, a rear wall 22, an outer side wall 23, and an inner side wall 24, and is formed in the shape of a rectangular frame in a cross-sectional view perpendicular to the longitudinal direction of each rail section 2,2. The outer side wall 23 is provided with a pair of rail pieces 231 and 232 at the front and rear, which are spaced apart along its longitudinal direction so that a bolt shaft can be inserted, thereby forming the rail groove 4. The spacing between each rail piece 231, 232 is configured to be larger than the outer diameter of the bolt shaft of a member Z to which a bolt with a bolt head is connected, or to a member Z to which a bolt with a nut screwed onto the bolt shaft is connected, and smaller than the minimum width of the bolt head or nut. This dimensional relationship allows the bolt shaft to be inserted between the pair of rail pieces 231, 232, while preventing the bolt head or nut from passing between the pair of rail pieces 231, 232 and coming out of the rail groove 4. Furthermore, by receiving and holding the bolt head or nut of the bolt originally provided by member Z in the rail groove 4, member Z can be suspended without separately providing a dedicated suspension part such as a hook, suspension ring, or hole on member Z. Here, the bolt head of member Z to which a bolt with a bolt head is connected, or the nut of member Z to which a bolt with a nut screwed onto the bolt shaft is connected, is inserted into the space enclosed by the front wall 21, the rear wall 22, the outer side wall 23, and the inner side wall 24. The spacing between each rail piece 231, 232 is preferably set to a dimension that allows the bolt shaft to swing from side to side when a bolt head or nut is inserted, as shown in Figure 5.

[0024] By allowing the bolt shaft to swing in this manner, even if there are variations in the shape, center of gravity, or suspension position of the member Z, the member Z can more easily assume a stable position due to its own weight. Furthermore, when adjacent member Z come into contact with each other, the swing of the bolt shaft releases the contact force, preventing excessive force from acting on the member Z or the suspension device 1. The openings of the rail grooves 4 formed in the pair of rail sections 2, 2 are preferably arranged to face in opposite directions, i.e., outward to the left and right of the suspension device 1, as shown in Figure 3. This allows the member Z suspended from one rail section 2 and the member Z suspended from the other rail section 2 to be held separately on the left and right sides of the suspension device 1. As a result, it becomes easier to secure the space formed between the pair of rail sections 2, 2, and the insertion and removal of the fork claws can be performed smoothly. Furthermore, excessive overlapping or entanglement of the member Z can be suppressed.

[0025] The configuration of the rail section 2 and rail groove 4 is not limited to the configurations shown in Figures 1 to 4. For example, as shown in the schematic configuration plan view of Figure 6, that is, the plan view from the direction of arrow B in Figure 1, each rail section 2,2 can be configured in a cylindrical shape, and a notch 233 through which a bolt shaft can be inserted can be formed along the longitudinal direction of each rail section 2,2 on the opposite side of the faces of the rail sections 2,2 facing each other, thereby forming the rail groove 4. The rail section 2 can also be formed in a C-shaped cross section, a U-shaped cross section, a cylindrical cross section, or any cross-sectional shape with a part that is open. An introduction section may be provided at the upper end of the rail section 2 to guide the bolt head or nut into the rail groove 4. This introduction section can be made of an expanding section, a notch, an inclined surface, or a curved surface, etc., whose opening width increases towards the upper end of the rail groove 4. This makes it easy to insert the bolt head or nut into the rail groove 4, and improves the efficiency of the installation work of member Z.

[0026] The stopper 5 prevents the bolt heads and nuts, which are passed through the space enclosed by the front wall 21, rear wall 22, outer side wall 23, and inner side wall 24, from coming loose and falling out from the lower end of the rail section 2, and is provided at the lower end of each rail section 2,2, which is the other end. In the configurations shown in Figures 1 to 4, the stopper 5 is constructed by not forming a notch for forming the rail groove 4 at the lower end of the outer side wall 23 of each rail section 2,2. The configuration of the stopper 5 is not particularly limited to the configurations shown in Figures 1 to 4, and for example, the stopper 5 can also be constructed by arranging a closing member that closes the opening at the lower end of each rail section 2,2, or a rod member that connects the lower ends of the front wall 21 and rear wall 22 of each rail section 2,2. The stopper 5 may also be constructed from bolts, pins, locking claws, opening / closing covers, rotating members, or sliding members. If the stopper 5 is configured to be detachable or openable, the member Z can be attached to or removed from the lower end of the rail section 2 as needed. The stopper 5 may also be equipped with a locking mechanism to prevent it from being unintentionally released while the member Z is suspended.

[0027] Furthermore, as shown in Figures 1 to 4, the suspension device 1 may be configured to include a rod-shaped reinforcing part 6 that connects the lower ends of the other ends of each rail section 2, 2. The reinforcing part 6 and each rail section 2, 2 are firmly connected to each other, for example, by welding. Although this reinforcing part 6 is not an essential component, it is preferable to provide it from the viewpoint of improving the strength and durability of the suspension device 1. It is also preferable that this reinforcing part 6 be made of a metal material. In addition, it is preferable that each end of this reinforcing part 6 is positioned within the rail groove 4 of the rail section 2 and also functions as the stopper 5 described above. By having the reinforcing part 6 also function as the stopper 5, the number of parts and manufacturing steps can be reduced. Furthermore, relative misalignment of the lower ends of each rail section 2, 2 can be suppressed, and opening, twisting, or deformation of the suspension device 1 when multiple members Z are suspended can be suppressed. Furthermore, the reinforcing portion 6 may be provided with legs or ground contact points to stabilize the posture of the suspension device 1 when it is placed on the floor or on a loading platform.

[0028] As shown in Figures 7 and 8, the suspension device 1 according to the present invention is used by inserting the bolt head of a member Z to which a bolt having a bolt head is connected, or the nut of a member Z to which a bolt with a nut screwed onto the bolt shaft is connected, into the rail groove 4 from the upper side to the lower side of each rail section 2, 2. In Figure 7, a clamp member Z, which is one of the components that make up a temporary scaffold, is shown as an example of a member Z to be suspended, and the bolt head of the bolt on this clamp member Z is shown inserted into the rail section 2. Figure 8 shows a state in which multiple clamp members Z are suspended from the suspension device 1.

[0029] The clamp member Z is suspended from the outside of the rail section 2 by having its bolt head or nut held within the rail groove 4 and its bolt shaft protruding outward from between a pair of rail pieces 231, 232. As shown in Figure 8, multiple clamp members Z are suspended from the outside of the suspension device 1, lined up along the longitudinal direction of each rail section 2. Therefore, each clamp member Z can be visually inspected from the outside without removing it from the suspension device 1, allowing for efficient confirmation of the quantity, identification of the type, visual inspection, inspection, or sorting of the clamp members Z. The member Z suspended from the suspension device 1 is not particularly limited to this clamp member Z, but can be any member Z to which a bolt with a bolt head is connected, or a member Z to which a bolt with a nut screwed onto the bolt shaft is connected. For example, right-angle clamps, swivel clamps, triple clamps, fixing fittings, connecting fittings, brackets, and other members equipped with bolts or nuts used in temporary scaffolding can be suspended.

[0030] When transporting the suspension device 1, which has multiple members Z suspended from it, it is done by hooking it onto the forks of a forklift. Specifically, the suspension device 1 is hung from the forks in such a manner that the tip of the fork is inserted into the space formed between a pair of rail sections 2, 2, so that the connecting section 3 rests on the upper surface of the fork. In this state, one rail section 2 hangs down on one side of the fork, and the other rail section 2 hangs down on the other side of the fork. As a result, the load of the multiple members Z suspended from each rail section 2 can be distributed to both sides of the fork, making it easier to stabilize the posture of the suspension device 1.

[0031] Furthermore, when the openings of each rail groove 4 face outward to the left and right of the suspension device 1, each member Z is positioned on the opposite side of the space between the pair of rail sections 2,2, thus suppressing interference between the fork tines and the member Z. The number of clamp members Z that make up the temporary scaffolding is enormous, but for all of the clamp members Z, the worker repeatedly performs the task of suspending multiple clamp members Z from the suspension device 1, as shown in Figure 8, and then hanging them from the fork tines of the forklift.

[0032] Multiple suspension devices 1 can be suspended from a single fork tine by arranging them along the longitudinal direction of the fork tine. Once the suspension devices 1 have been attached to the fork tines, the forklift is moved to where the transport truck is parked, and the fork tines are positioned above the truck bed. The operator slides the suspension devices 1 hanging from the fork tines along the fork tines, removes them from the fork tines, and places them on the truck bed, thus completing the loading onto the transport truck. The suspension devices 1 can be slid along the longitudinal direction of the fork tines with the connecting part 3 in contact with the upper surface of the fork tines. Therefore, the suspension devices 1 can be easily attached to or removed from the fork tines without large vertical or horizontal movements of the fork tines.

[0033] Furthermore, when assembling temporary scaffolding at another construction site, the forklift is moved near the transport truck, and its forks are positioned above the loading platform. Then, the components Z loaded on the loading platform, such as clamp components Z, are suspended by the suspension devices 1, which are then passed through the forklift's forks and hung up. When it becomes impossible to suspend more than a predetermined number of suspension devices 1 from the forks, the forklift is moved to the temporary scaffolding assembly site.

[0034] Subsequently, the lifting device 1 is removed from the fork tines, placed in the designated location, and then the component Z is removed from the lifting device 1 for use. In this way, multiple components Z can be transported together from the transport truck to the construction site while still suspended from the lifting device 1, thus streamlining the loading and unloading process compared to transporting the components Z one by one or in storage bags.

[0035] The suspension device 1 according to this invention is configured to be able to suspend multiple members Z, such as clamp members Z, and to be hung from the forks of a forklift. Therefore, compared to the conventional method of placing multiple clamp members Z into a storage bag and then carrying this storage bag to where the transport truck is parked and loading it onto the truck bed, the burden on the worker can be significantly reduced. Furthermore, it is possible to prevent the storage bag from being accidentally dropped during transport. In addition, since the clamp members Z can be held in an aligned state along the rail section 2, it is possible to suppress the clamp members Z from becoming entangled in a disorderly manner. Furthermore, collisions between bolts, nuts, or jaws can be suppressed, and damage to the clamp members Z can be reduced.

[0036] Furthermore, as described above, instead of hanging the suspension device 1 from the forks of a forklift, the worker can hold the connecting part 3 to transport the suspension device 1 with the component Z suspended from it to the location of the transport truck and place it on the truck bed. Because it is equipped with a connecting part 3 that serves as a handle, it is possible to firmly grip the suspension device 1 with the component Z suspended from it compared to transporting it in the conventional way using a storage bag, thereby improving the worker's transport efficiency. In addition, gripping parts, covering parts, uneven parts, or elastic members may be provided in the center or at both ends of the connecting part 3 to prevent the worker's hand from slipping.

[0037] Furthermore, as mentioned above, temporary scaffolding is often rented or leased, and companies that rent out temporary scaffolding store the parts that are not being rented out, for example, in a warehouse. With the suspension device 1 according to the present invention, by setting up a storage shelf in advance in a warehouse or other storage location, which has multiple rod-shaped members that hang multiple suspension devices 1, i.e., suspension devices 1 with members Z suspended from them, the workload on workers during storage can be reduced. In addition, the efficiency of maintenance and inspection work can be improved.

[0038] The storage shelf can be configured to include a shelf body installed on the floor and one or more rod-shaped members projecting horizontally or diagonally upward from the shelf body. The rod-shaped members have an outer diameter or width capable of supporting the connecting portion 3 of the suspension device 1. Preferably, the rod-shaped members are positioned to be the same height and extending direction as or similar to the fork tines of the forklift. This allows the tips of the fork tines and one end of the rod-shaped members to be close to or in contact with each other, enabling the suspension device 1 to slide continuously from the fork tines to the rod-shaped members.

[0039] To explain in more detail, for example, after moving a transport truck loaded with the lifting device 1 to the entrance of a warehouse, a forklift is moved near the transport truck, and its forks are positioned above the truck bed. The components Z loaded on the truck bed, such as clamp components Z, are then suspended by the lifting device 1 through the fork keys, and when it becomes impossible to suspend any more lifting devices 1 from the fork keys, the forklift is moved to near a storage shelf installed in the warehouse.

[0040] Next, align the tip of the forklift's forks with one end of the rod-shaped member provided on the storage shelf. If possible, operate the forklift so that the tip of the fork is in contact with or close to one end of the rod-shaped member. Then, slide the suspension device 1 hanging from the fork on the fork and remove it from the tip of the fork, while moving it towards the rod-shaped member on the storage shelf.

[0041] In this way, by bringing the tip of the fork claw close to or in contact with one end of the rod-shaped member of the storage shelf, the suspension device 1 can be continuously slid from the fork claw to the rod-shaped member. Therefore, without removing the member Z from the suspension device 1, it is possible to easily transition from the transport state to the storage state while keeping multiple members Z suspended. If multiple suspension devices 1 are moved to the rod-shaped member side and it is no longer possible to hang any more suspension devices 1 from that rod-shaped member, the fork claw is moved to another rod-shaped member side, and the suspension devices 1 are moved again in the same manner from the fork claw side to the rod-shaped member side. Furthermore, the rod-shaped member may be provided with a shelf-side stopper to prevent the suspension device 1 from unintentionally falling off from its tip. The shelf-side stopper can be configured to be detachable or openable.

[0042] As described above, the suspension device 1 according to the present invention allows for the transport of components Z, such as clamp components Z, using a forklift. Furthermore, since movement from the forklift to the rod-shaped component side of the storage shelf only requires sliding, the workload on workers can be significantly reduced. In addition, instead of storing components Z in stacks of storage bags in the warehouse as in the conventional method, components Z can be stored in an orderly manner on the storage shelf. Moreover, since components Z are stored suspended from the suspension device 1 in a state where they can be seen from the outside, inspection of components Z can be carried out efficiently. Furthermore, the components Z can be transported by forklift, loaded onto transport trucks, transferred to storage shelves, stored in the warehouse, and maintained and inspected while remaining suspended from the suspension device 1. Therefore, the work of transferring components Z one by one into storage bags, pallets, or storage shelves between each process can be omitted or reduced. Furthermore, since the individual components Z suspended from the storage shelves can be inspected, it is easy to check for deformation, damage, rust, missing bolts or nuts, etc. In addition, by storing components Z separately according to their type, dimensions, or use for each rod-shaped component in the storage shelf, the sorting and inventory management of components Z can be made more efficient.

[0043] The number of members Z suspended from each rail section 2 is not particularly limited and can be appropriately set according to the length of the rail section 2, the size and weight of the members Z, and the allowable load of the suspension device 1. Also, the number of members Z suspended from a pair of rail sections 2,2 may be the same or different. From the viewpoint of stabilizing the posture of the suspension device 1, it is preferable to arrange the members Z so that the load acting on the pair of rail sections 2,2 is approximately equal.

[0044] Furthermore, the present invention can also be configured as a storage system including the above-described suspension device 1 and a storage shelf equipped with one or more rod-shaped members that support the suspension device 1. In this storage system, the rod-shaped members of the storage shelf are insertable between a pair of rail sections 2, 2 of the suspension device 1 and are configured to support the connecting section 3 from below. Preferably, the tip of the rod-shaped member is configured to be able to approach or abut against the tip of the fork tines of a forklift, and the suspension device 1 is configured to be able to slide from the fork tines to the rod-shaped member, or from the rod-shaped member to the fork tines.

[0045] Furthermore, this invention can also be configured as a transport method that includes a suspension step of suspending member Z from the suspension device 1, a support step of inserting the fork tines of a forklift between a pair of rail sections 2, 2 of the suspension device 1 and placing the connecting section 3 on the upper surface of the fork tines, and a transport step of transporting the suspension device 1 by a forklift. Moreover, this transport method may include a transfer step of bringing the tips of the fork tines close to or in contact with the tips of the rod-shaped members of the storage shelf and sliding the suspension device 1 from the fork tines to the rod-shaped members. With this method, member Z can be transitioned from a transport state to a storage state without being removed from the suspension device 1.

[0046] This invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention. For example, the pair of rail sections 2, 2 may have the same length or shape, or they may have different lengths or shapes. Also, the rail section 2 is not limited to two, but may be configured to include three or more rail sections. In this case, a space into which a fork claw can be inserted can be formed in at least one of the adjacent rail sections. Furthermore, at least one of the connecting section 3, stopper 5, and reinforcing section 6 may be configured to be detachable from the rail section 2. This allows the suspension device 1 to be disassembled for storage or transport. [Explanation of symbols]
