Modes for Carrying Out the Invention

[0008] [First Embodiment] Hereinafter, the first embodiment of the present disclosure will be described in detail with reference to the drawings. In the drawings, the wall surface W and the ceiling surface C of the building are represented by a two-dot chain line, and the thickness of the wall surface W and the ceiling height, etc. are not limited. Also, FIGS. 1 and 4 to 9 show a part of the wall surface W and the ceiling surface C in the interior of a building such as a house, and the length direction of the rails 2 and 2B is omitted.

[0009] As shown in FIG. 1, the suspension structure 1 of the present embodiment is used to suspend a hammock 5A as a suspended object in a building room from a rail 2 for use. The suspended hammock 5A is assumed to be used with a person on it.

[0010] The suspension structure 1 includes a rail 2, a suspension tool 3, a suspension wire 4, and a suspended object 5. In the first embodiment, a hammock 5A is provided as the suspended object 5. As shown in FIGS. 1 and 2, the rail 2 is fixed in a state of extending horizontally in the left - right direction with respect to the wall surface W. In the following description, "horizontal" or "parallel" includes not only complete horizontal or parallel but also substantial horizontal or parallel within a certain error range. The rail 2 is a shaped material obtained by extrusion - molding a metal such as aluminum, for example.

[0011] The rail 2 has a rail main body portion 21 and a holder 22. As shown in FIG. 3, the rail main body portion 21 has an upper plate portion 211, a lower plate portion 212, a connecting plate portion 213, and a guide portion 214. The upper plate portion 211 and the lower plate portion 212 are upper and lower plate members that are horizontally arranged in a state of being fixed to the wall surface W. The upper plate portion 211 has a protruding piece 211a on its lower surface. The connecting plate portion 213 has a shape that is crank - shaped in cross - section and is a plate member that connects the upper plate portion 211 and the lower plate portion 212 in the vertical direction.

[0012] The guide portion 214 has hook portions 214a and 214b. The guide portion 214 is a substantially C - shaped guide member that extends along the lower surface of the lower plate portion 212 in the longitudinal direction of the rail 2 and opens downward. Each of the hook portions 214a and 214b has hook pieces 215a and 215b that bend so as to face each other. The suspension tool 3 is engaged with and supported by these hook pieces 215a and 215b in a non - droppable manner and slidably along the rail 2. The rail 2 is fixed to the wall surface W by fastening a screw (not shown) driven into the connecting plate portion 213 from the indoor side to the wall surface W.

[0013] As shown in FIG. 2, the fixture 22 includes a main body portion 221 and paired receiving portions 222. The main body portion 221 has a hollow vertically long rectangular tube shape. The upper end portion of the main body portion 221 protrudes above the receiving portion 222, and the upper end surface is brought into contact with the ceiling surface C. Further, the main body portion 221 is arranged at the inner corner of the indoor wall surface W so that the axial direction is along the vertical direction. While maintaining this state, a screw (not shown) is fastened to the wall surface W to fix the fixture 22 to the wall surface W. The main body portion 221 has protruding pieces 223 that engage with the rail main body portion 21 on the side surface portion exposed to the indoor side.

[0014] The receiving portion 222 is a member that engages the fixture 22 with the rail main body portion 21 and horizontally holds the rail main body portion 21. The receiving portion 222 is provided in pairs on the side surface portion of the main body portion 221 exposed to the indoor side. As shown in FIG. 3, when the rail main body portion 21 is engaged with the fixture 22, the protruding piece 211a of the fixture 22 is engaged with the receiving groove 22a of the receiving portion 222. Thereby, the fixture 22 can hold the rail main body portion 21 easily and accurately.

[0015] As shown in FIGS. 2 and 3, the suspension tool 3 includes a fixed portion 31, a knurled screw 32, a fall prevention portion 33, and a hook 34. The fixed portion 31 is a member fixed to the guide portion 214 of the rail 2. It has a shape in which the left and right portions of the disc member are cut, and the size in the short direction is a size that fits into the opening of the guide portion 214. When fixing to the rail 2, the fixed portion 31 is rotated so that the short direction thereof is along the opening of the guide portion 214, and the fixed portion 31 is inserted into the hollow portion of the guide portion 214.

[0016] The knurled screw 32 is a screw member that rotates and moves the fixed portion 31 in the vertical direction. By rotating the knurled screw 32, as shown in FIG. 2, the fixed portion 31 can be rotated 90 degrees to hook the fixed portion 31 on the hook pieces 215a and 215b. Further, by rotating the knurled screw 32 further, the suspension tool 3 is completely fixed to the rail 2.

[0017] The suspension tool 3 is slidably attached to the rail 2, and the portion where the suspension tool 3 is fixed is the rail portion of the rail 2. In this embodiment, as shown in FIG. 1, the suspended object 5 is supported by a pair of rail portions that extend in the lateral direction and are not on the same straight line.

[0018] As shown in FIG. 1, the fall prevention portion 33 has a function of being locked by a spring and is a member that prevents the suspension wire 4 attached to the suspension tool 3 from falling off. The hook 34 is provided at the tip of the suspension tool 3 and can detachably connect the suspension wire 4 to the rail 2.

[0019] The suspension wire 4 is a wire that connects the suspension tool 3 and the suspended object 5, and a plurality of suspension wires 4 are provided according to the number of rail portions. The suspension wire 4 includes a thimble 41, which is a metal connecting fitting, and a wire 42. Two thimbles 41 are provided at the ends of the two wires 42. The suspension wire 4 of this embodiment is composed of two wires 42 in order to securely support the hammock 5A to which a load is applied, but depending on the content of the suspended object 4, it may be composed of one wire 42. Also, at the end of the wire 42, a thimble 41 composed of a simple single loop may be used, or a terminal fitting configured such that a part of the loop opens and closes may be used. Further, the thimble 41 and the terminal fitting may be used in combination.

[0020] The suspended object 5 is an article supported by the rail 2 via the suspension wire 4. In this embodiment, as shown in FIG. 1, a hammock 5A is used. The hammock 5A is a general hammock on which a person can ride, and the main body portion on which a person rides has a deformable mesh structure. The hammock 5A includes two support portions 51 and a buffer member 6 at both ends of the main body portion composed of a mesh.

[0021] The support part 51 is formed in a ring shape, and is suspended and supported from the rail 2 that extends through the wire 42 at the center of the ring so that the upper plate part 211 contacts the ceiling. The buffer member 6 is a shock absorber provided so as to wrap the support part 51. It may be composed of an elastic body such as rubber, or may be composed of a porous substance made of synthetic resin such as sponge. Since the load concentrates at the contact point between the wire 42 and the support part 51, by providing the buffer member 6, the impact applied to the support part 51 can be absorbed.

[0022] As shown in FIG. 1, in the suspension structure 1 of the present embodiment, the hammock 5A is suspended indoors using two rails 2 extending in an L shape. Two hanging tools 3 are provided on each rail part of each rail 2. After determining the hanging position, the hanging tool 3 is fixed to the rail part of the rail 2 by the knurled screw 32. The pair of rails 2 are respectively fixed to adjacent wall surfaces W and extend in a direction intersecting each other. The pair of rails 2 may extend in perpendicular directions.

[0023] The suspension wire 4 is provided so as to penetrate the hole part of the support part 51 of the hammock 5A. The thimbles 41 at both ends are fixed to the rail 2 via a pair of hanging tools 3 provided on the same rail 2. The two support parts 51 provided on the hammock 5A are suspended indoors by two suspension wires 4.

[0024] The height of the hammock 5A can be adjusted by changing the position of the suspension tool 3 provided on the rail 2. For example, if the paired suspension tools 3 are installed separately, the suspension wire 4 will open widely to the left and right with the support part 51 as the axis, so the position of the support part 51 can be raised. Conversely, if the paired suspension tools 3 are installed closer to each other, the suspension wire 4 will close with the support part 51 as the axis, so the position of the support part 51 will be lowered and the height of the hammock 5A will approach the floor. It is also possible to install the two support parts 51 at different heights. For example, when lying horizontally on the hammock 5A, the support part 51 in the direction where the head is placed can be made higher, etc., and the hammock 5A can be suspended in the room at a free height. Also, the height of the hammock 5A can be adjusted by changing the length of the wire 42.

[0025] With this configuration, by using the two rails 2 extended on the wall surface W, the hammock 5A can be very easily suspended and installed within the extended range of the rail 2 via the suspension wire 4. Also, by adjusting the position of the suspension tool 3, the installation height and installation position can be freely adjusted.

[0026] Conventionally, a method of suspending and installing a painting or the like using a wire on the wall surface corresponding directly below the rail 2 has been used. However, according to the suspension structure 1 of the present embodiment, the suspended object 5 can be freely suspended and installed at a place away from the wall surface W, and the indoor space can be utilized more effectively.

[0027] By using the two rails 2 extended in an L shape, the limited space can be utilized, and a relaxation space can be provided using the corner part of the room. Since there is no need for a support column or the like for supporting the hammock 5A and it is a structure that is suspended from the rail 2 extended so as to contact the ceiling and the wall, it is not restricted by the layout of the floor and the wall surface, and an original space utilization making use of the ceiling can be achieved.

[0028] Also, when removing the hammock 5A, since it is only necessary to remove the suspension wire 4 from the suspension tool 3, no tools or construction work are required. With this configuration, the indoor layout can be changed very easily, and the hammock 5A can be simply installed and removed as needed.

[0029] As a modification of the suspended object 5, as shown in FIG. 4, a swing 5B, as shown in FIG. 5, a suspension device 5C, and as shown in FIG. 6, a ladder 5D may be provided respectively. Hereinafter, each modification will be described.

[0030] As shown in FIG. 4, the swing 5B is a swing of a play equipment composed of a single plate. Both ends of the seat surface respectively have a support portion 51B and a buffer member 6. The support portion 51B is a semi-circular support fitting and has the strength to surely receive the load and stress when using the swing. The support portion 51B is wrapped by the buffer member 6. The suspension wire 4 supports the swinging movement of the swing back and forth and is surely fixed to the rail 2. The fall prevention portion 33 of the suspension tool 3 suppresses the falling out of the thimble 41 of the suspension wire 4, and also, the buffer member 6 absorbs the impact of the wire 42 due to the movement of the swing, so that the swing 5B can surely maintain the suspension structure 1 even in the use state. Also, if sufficient strength can be maintained, an annular support portion 51B may be used.

[0031] Next, as shown in FIG. 5, the suspension device 5C may be used for the suspension structure 1. The suspension device 5C is a rod-shaped device used by a person hanging. The suspension device 5C respectively has, at both ends, a 51C which is a semi-circular support fitting and a buffer member 6. Since the configuration, effects, etc. are the same as those of the swing 5B described above, the description thereof will be omitted.

[0032] Next, the ladder 5D shown in FIG. 6 will be described. The ladder 5D is a ladder-shaped device used for training, and horizontal rungs are provided at equal intervals between two columns. A total of four support parts 51D, which are semi-circular support fittings, are provided at both ends of the two columns. Each of the support parts 51D is wrapped by a buffer member 6. By arranging the four support parts 51D in a well-balanced manner, rattling of the device and excessive sway during the use of the ladder 5D can be suppressed. Also, if sufficient strength can be maintained, an annular support part 51D may be used. The ladder 5D can be suspended and installed with different heights of the four support parts 51D. For example, the ladder 5D installed such that the horizontal rungs gradually become higher in the advancing direction can impose an additional load on the movement.

[0033] The present disclosure is not limited to the above-described embodiments and can be appropriately modified. For example, in this embodiment, the suspended objects 5 are suspended and installed one by one, but a combination of multiple types of suspended objects 5 can also be installed. The suspended objects 5 can be freely configured according to the length of the rail 2, and by installing them at different heights, a free and moving space can be easily created.

[0034] Also, in this embodiment, the hammock 5A having two support parts 51 is supported by four suspension tools 3, and the ladder 5D having four support parts 51D is supported by eight suspension tools 3. In this embodiment, two suspension tools 3 are used for one support part, but the present disclosure is not limited thereto. As shown in FIG. 7, one support part 51 may be supported by one suspension tool 3 via a suspension wire 4. In that case, a pair of thimbles 41 of the suspension wire 4 can be connected to the same hook 34 of the suspension tool 3.

[0035] Similarly, the four support parts 51D of the ladder 5D may be supported by two suspension tools 3 via four suspension wires 4. In this embodiment, the number of suspension wires 4 and suspension tools 3 used for one support part is not limited, and a free configuration can be made according to the weight of the suspended object 5.

[0036] [Second Embodiment] Next, the second embodiment of the present disclosure will be described in detail with reference to the drawings. The difference between the suspension structure 1B of the second embodiment and the first embodiment lies in the arrangement shape of the rail 2 used in the suspension structure. Since the other configurations are the same as those of the first embodiment, the description thereof will be omitted.

[0037] As shown in FIG. 8, the rail 2 used in the suspension structure 1B extends with respect to the opposing wall surfaces W provided in parallel. The other configurations are the same as those of the first embodiment, and the hammock 5A as the suspended object 5 is also the same. Even when the hammock 5A is suspended using the rails 2 provided in parallel, the height of the hammock 5A can be adjusted by changing the position of the suspension tool 3, which is the same point.

[0038] According to this configuration, for example, since a part of the indoor wall has a tile finish, even in a room where it is desired to avoid driving screws into the adjacent wall surface for the construction of the rail 2, by using the suspension structure 1B, a simple spatial effect with the suspended object 5 installed can be achieved. Further, by combining the first embodiment and the second embodiment and freely installing the suspended object 5 indoors, it is possible to easily create a more dynamic and free space.

[0039] As a modification of the suspended object 5, a catwalk 5E may be provided as shown in FIG. 9. The catwalk 5E is a suspension bridge for cats assembled in a ladder shape. Usually, a catwalk is often provided fixed to the wall surface W, but according to the suspension structure 1B, the catwalk 5E can be installed floating in the air, and the catwalk 5E can be used more freely.

[0040] The catwalk 5E has, at both ends of the tread provided on the outside, support fittings 51E which are semi-circular in shape, and a buffer member 6, respectively. Since the configuration, effects, etc. are the same as those of the above-described fire escape ladder 5D, the description thereof will be omitted.

[0041] The present disclosure is not limited to the above-described embodiments and can be appropriately modified. For example, in this embodiment, the rails 2 were provided in parallel, but depending on the shape of the room where they are installed, they may be provided in a shape such that the distance between the two rails 2 gradually narrows or widens on the opposing wall surfaces W. The installation of the rails 2 can be appropriately changed according to the shape of the room where they are installed. Also, the installation heights of the two rails 2 provided may be different. Since the height of the support portion 51 can be changed depending on the position of the suspension tool 3 or the length of the wire 42, even if the heights of the rails 2 are different, the suspended object 5 can be installed horizontally.

[0042] [Third Embodiment] Next, the third embodiment of the present disclosure will be described in detail with reference to the drawings. The difference between the suspension structure 1C of the third embodiment and the first embodiment lies in the shape and number of the rails 2 used in the suspension structure. Since the other configurations are the same as those of the first embodiment, the description thereof will be omitted.

[0043] As shown in FIG. 10, the wall surface W of this embodiment is configured in a continuous arc shape. Therefore, the rail 2B used is also formed in a single arc shape along the longitudinal direction so as to follow the wall surface W. Since the other configurations of the rail 2B are the same as those of the rail 2, the description thereof will be omitted.

[0044] In this embodiment, a pair of rail portions are provided on a single rail 2B, and four suspension tools 3 are provided. Since the rail 2B has an arc shape, a pair of rail portions can be provided, and even if there is only one rail, the hammock 5A can be suspended and installed using the suspension structure 1C. According to this configuration, the suspension structure 1C can be used with a minimum amount of rail installation, the man-hours can be reduced, the suspended object 5 can be easily installed, and a free space can be created.

[0045] The present disclosure is not limited to the above-described embodiments and can be appropriately modified. For example, in this embodiment, the arc-shaped rail 2B is used, but the shape of the rail 2B is not limited to this. For example, for a wall surface W configured in an S shape or a free curve shape, the hanging structure 1C can be used by providing one rail 2B having a shape along the wall surface W.

[0046] Further, the suspended object 5 is not limited to the articles described in the present disclosure. For example, for a suspended cabinet, a foliage plant, a decoration such as an ornament, a suspended lighting, etc., any article can be suspended and installed indoors according to the present disclosure as long as a support portion is provided on the suspended object. Also, when the suspended object 5 is lightweight or the like and the load on the wire 42 is small, the buffer member 6 can be omitted.

[0047] Furthermore, although the rail 2 of the present disclosure extends horizontally along the ceiling surface C, the rail 2 can also be provided in a staircase room or an attic room where the ceiling surface C is inclined. The rail of the present disclosure can be extended to any ceiling surface C and wall surface W in the building. Also, the number of rails can be increased or decreased as needed, and for a wall surface W where the hanging tool 3 is not provided, the rail does not need to be extended.
