Description

[Detailed description of the invention] 【Technical field】

The present invention relates to swings, particularly swings used at home.

[Background technology] Household swings used indoors or in the garden are
They are usually designed to be foldable for convenience when storing or transporting them, but conventionally they have been provided with a pair of chair-shaped seats placed opposite each other. In this method, two sets of columns are prepared that are rotatably connected at their upper ends, and a pair of sheets are suspended from the upper frame supported by these columns through suspension members each made of a pipe. Therefore, for storage, etc., the two sets of supports can only be folded so that the opening angle is the minimum, so if they are folded for storage, the floor space required for storage will be reduced. However, the height increases, which limits the storage space, and also poses the problem that the bulk of the package cannot be reduced during transportation. Further, the height cannot be adjusted depending on the age of the child using the device.

[Purpose of the invention]

The present invention has been developed in view of these points, and its purpose is to make it possible to reduce the bulk when stored and stored, and also to be able to freely adjust the height. There are swings available.

Accordingly, the present invention provides a swing in which a pair of seats are suspended from an upper frame supported by a plurality of pillars via hanging members, in which each pillar formed of pipe material is expandable and contractible. It shall be equipped with a first locking mechanism that fixes it to the required length, and the suspension member formed of a pipe material that is rotatably connected to the upper frame is expandable and contractable and fixed to the required length. The present invention is characterized by being equipped with a second locking mechanism that allows the length of both the support and the hanging member to be shortened when stored. The present invention will be described below in detail based on the illustrated embodiment. It is composed of a pair of chair-shaped seats 4, 4 suspended through a pair of chair-shaped seats 4, 4, and a footrest 5 located below between the opposing seats 4, 4. Both seats 4, 4 are placed on the footrest 5. Because they are connected together, both seats 4, 4 can swing at the same time. Each of the above-mentioned pillars 1 is made telescopically telescopic by combining two pipe materials 11 and 12 with different diameters, and is equipped with a locking mechanism 6 to fix it to a desired length. There is.
The upper ends and lower ends of two of the four pillars 1 are connected by an upper horizontal bar 13 and a lower horizontal bar 14, respectively, to form two sets of trapezoidal frames. The pillars 1, 1, which form the side pieces, are rotatably connected at their upper ends. 18 in the diagram
is a cover that covers this rotatable connection part. The upper frame 2, which is supported by these supports 1 and has a rectangular planar shape, is connected to the tips of the opposite side pieces of a pair of U-shaped pipes 21 and 22 through a connecting member 23. It is said that it can be folded freely by connecting it movably, and each side piece is attached to each support column 1.
It is attached so that it can rotate freely in a vertical plane. The two hanging members 3, 3 for suspending the pair of sheets 4, 4 from the upper frame 2 include a lower pipe 31 bent in a U-shape, and a telescopic type attached to both sides of the lower pipe 31. A locking mechanism 7, which is telescopic and consists of a pair of combined upper pipes 32, 32, is used to fix both side pieces to a required length.
The upper ends of both side pieces are connected to the upper frame 2 by hooks 30, 30, so that they can swing freely. Further, the lower ends of the two hanging members 3, 3 to which the seats 4 are attached are connected to each other by a connecting bar 50 which is flexible at the center, and the footrest 5 is It is attached to 50. The seat 4, which is formed into a chair shape by rotatably connecting the seat plate 40 and the back plate 41, has both sides of the tip of the seat plate 40 rotatably connected to the suspension member 3, and A support frame 42 rotatably connected to the lower member 3 is rotatably connected to the back plate 41, and a seat plate 40 is further provided between the seat plate 40 and the hanging member 3.
Flexible link 4 for regulating the rotation angle of
3 is installed. Next, the lock mechanism 6 provided on the support column 1 will be explained. As shown in FIG. 3, this consists of a cylindrical body 60 made of synthetic resin, a lever 61 whose center portion is rotatably held by the cylindrical body 60 by a shaft 62, and a lever 61 provided at one end of the lever 61. The engagement pin 63 that protrudes into the cylinder body 60 and the other end side of the lever 61 and the cylinder body 6
0, the engagement pin 63 is arranged between the cylinder body 6
The cylindrical body 60 has a small diameter portion 65 at one end, a protrusion 66 surrounding the lever 61 on the outer peripheral surface, and a spring 64 that biases the lever 61 in the direction of protruding inward. A groove 67 is provided. The upper end of the lower pipe material 11, which is the larger diameter side of the two pipe materials 11 and 12 constituting the support column 1, is inserted into the cylinder body 60, and the upper end of the lower pipe material 11, which is the larger diameter side of the two pipe materials 11 and 12 constituting the support column 1, is inserted into the cylinder body 60, and the upper end of the lower pipe material 11, which is the larger diameter side, is inserted into the cylinder body 60, and the upper end of the lower pipe material 11, which is the larger diameter side, is inserted into the cylinder body 60. By tightening the provided tightening screw 68, the lock mechanism 6 is fixed to the pipe material 11. On the other hand, the pipe material 12 whose one end is inserted into the pipe material 11 and slides into contact with the inner surface of the small diameter portion 65 of the cylinder 60 is
Locking holes 19 are bored at appropriate intervals in the longitudinal direction, and by fitting the engaging pin 63 into any of the locking holes 19, sliding of the pipe material 12 with respect to the pipe material 11 is prevented. The length of the support column 1 is fixed. When the lever 61 is rotated by pushing in the end side of the lever 61 that is biased by the spring 64, the engagement pin 6
3 is detached from the engagement hole 19, the pipe material 1
The pipe material 12 can be freely drawn out and stored relative to the support 1, and the support 1 can be expanded and contracted. At this time, the engagement pin 63 provided on the lever 61
However, since the lever 61 is attached to the cylindrical body 60 so that it is located above the shaft 62 which is the center of rotation of the lever 61, when extending the support column 1, it is necessary to As shown, pipe material 11
By simply pulling out the pipe material 12 against the button, the edge of the engagement hole 19 pushes the engagement pin 63 and rotates the lever 61, causing the engagement pin 63 and the engagement hole 19 to rotate.
For this purpose, there is no need to apply any operating force to the lever 61. Of course, regarding the direction in which the column 1 is contracted, which corresponds to the direction of the load applied to the column 1,
Since the engagement pin 63 will bite into the engagement hole 19, the engagement between the engagement pin 63 and the engagement hole 19 will not be released unless an operating force is applied to the lever 61. However, in this case as well, the engagement between the engagement pin 63 and the engagement hole 19 is released by immediately extending the support 1, and then the support 1 is retracted while holding the lever 61 so that it does not return. This procedure can be taken. The locking mechanism 7 provided on the hanging member 3 has the same structure as the locking mechanism 6 provided on the pillar 1, and as shown in FIG.
, a lever 71 whose central portion is rotatably held in the cylinder 70 by a shaft 72 , and an engagement pin 73 provided at one end of the lever 71 and protruding into the cylinder 70 .
and a spring 74 disposed between the other end of the lever 71 and the cylindrical body 70 to bias the lever 71 in a direction in which the engaging pin 73 protrudes into the cylindrical body 70. The cylindrical body 70 has a small diameter portion 75 at one end thereof.
is provided with a protrusion 76 surrounding the lever 71 on the outer peripheral surface and a split groove 77 on the other end, and the upper end of the lower pipe material 31 of the hanging member 3 is inserted into the cylinder body 70,
By tightening the split groove 77 with the tightening screw 78, the lock mechanism 7 is fixed to the lower pipe material 31. The engaging pin 73 adjusts the hanging material 3 to a desired length by engaging with one of the plurality of engaging holes 39 bored at appropriate intervals in the upper pipe material 32. Fix it. However, unlike the lock mechanism 6 provided on the support column 1, this lock mechanism 7 has an engaging pin 73.
The lever 71 is mounted upside down so that the lever 71 is located below the shaft 72 that supports the lever 71. Therefore, the engaging pin 73
For the direction in which the upper pipe material 32 is inserted into the lower pipe material 31 while biting into the engagement hole 79, the fourth
As shown in FIG. b, the engagement pin 73 is pushed by the edge of the locking hole 79, causing the lever 71 to rotate. In other words, the lock mechanism 7 provided on the hanging member 3
The lever 7 is securely locked in the extending direction, which is the direction in which the load of the user sitting on the seat 4 is applied.
There is no need to add any operations to 1. Therefore, the lengths of the pillars 1 and hanging members 3 are set to the minimum, the upper frame 2 is folded to minimize the opening angle of the pillars 1, and the connecting bar 50 with the footrest 5 attached and the seat 4 When folded, this swing becomes as shown in Figure 5.
It has a very small volume, requires less space for storage, and is easier to package and transport. Incidentally, the operation of shortening the length of the hanging member 3 can be performed without operating the lock mechanism 7, as described above. When using it as a swing, please use the upper frame 2.
What is necessary is to open the support column 1, stretch the support column 1 and the hanging member 3, and then unfold the sheet 4 and the connecting bar 50. The extension of the strut 1 can be carried out without operating the locking mechanism 6 as described above. By appropriately adjusting the length of the support column 1 and the length of the hanging member 3, the height can be adjusted as shown in FIGS. 1 and 2. By the way, all four pillars 1 are assembled into trapezoidal frames, two each, and for this reason, the pillars 1
When the length is changed, the distance between the lower ends of the pair of supports 1, 1, which are both sides of the trapezoidal frame, also changes. For this purpose, the lower horizontal crosspiece 14 connecting the lower ends must also be able to expand and contract, but here two pipes 15 and 16 with different diameters are combined in a telescopic manner. The lower horizontal crosspiece 14 is made of a material that is only extendable and retractable. A locking mechanism is originally required to prevent both supports 1, 1 from spreading when a load is applied, but in reality, when a load is applied, the locking mechanism is inserted into the pipe 15. This is because distortion occurs between the pipe 16 and the support pillars 1, 1 from spreading out. In the figure, 10 is a chain connecting the pair of lower horizontal bars 14, 14.

[Effects of the Invention] As described above, in the present invention, the lengths of both the support and the hanging material from which the seat is hung can be changed, and therefore the space required for storage is reduced. In addition, it is possible to reduce the bulk during packaging and transportation.
