DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable swing used mainly for indoor use.

[0002]

2. Description of the Related Art Heretofore, as a swing of this type, the upper ends of a trapezoidal frame in which the lower ends of a pair of pillars are connected by a lower horizontal bar are rotatably connected to each other. There is known a structure which supports a material and folds it when moving or storing, while using a trapezoidal frame to ensure stability during use. However, according to such a structure, since the height in the folded state is high, it is difficult to store it in a closet or a storage room of a general household, and there are limitations on a storage place and packing and transportation. In order to solve this, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 63-172482, both columns and the lower horizontal bar in the trapezoidal frame are made expandable and contractable, and the telescopic columns and the lower horizontal bar are shortened during storage. There is also known a structure in which the bulk during storage is reduced. However, with such a structure, it is necessary to shorten the lower horizontal rod first when folding, and then to shorten the left and right columns, and also to lengthen the lower horizontal rod after extending the columns during assembly, Work becomes troublesome. In addition, this type of swing is generally provided with an upper frame at an upper end of a trapezoidal frame, and a hanging material is supported through the upper frame. However, since the conventional swing uses a trapezoidal frame, the upper end of the trapezoidal frame and the upper frame are used. The space between the child and the child becomes narrow, and there is a risk that the child may get his hands or hit his head when getting on or off the vehicle.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to reduce a storage space and to perform storage and assembly with one touch. To provide a foldable swing.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides two sets of frame frames which are connected by a horizontal rod between upper ends and lower ends of a pair of columns. In a folding swing that supports a hanging member to which a sheet is attached with these frame frames, the two sets of frame frames are
The gist of the present invention is that the support member is formed in a rectangular shape such as a rectangular shape or a square shape, and is provided with a lock mechanism that allows each of the columns to be stretchable and fixed to a predetermined length.

In this case, since the frame is formed in a rectangular shape, it can be folded simply by shortening the columns during storage, and the columns can be lengthened during assembly. In addition, when an upper frame is provided at the upper end of the frame frame and the suspending member is supported via the upper frame, the space between the upper frame portion and the upper frame is increased because the frame frame has a rectangular shape. When a child gets on and off the vehicle, there is little risk of pinching his hands or hitting his head.

[0006] In order to improve the stability during use, it is preferable to provide outwardly protruding overturning members on both the left and right sides of the lower end of each of the frame frames.

[0007] As the overturn prevention member, the lower end of the column is bent outward, the outer end of the lower horizontal rod is extended outside the column, or the lower end of the column is made of the same material or a different material as the column or lower horizontal rod. Alternatively, various modes can be exemplified, such as fixing to the outer end of the lower horizontal rod via fixing means such as welding, bonding, screwing, fitting, or the like, and attaching a small-diameter member to the outer end of the lower horizontal rod so as to be freely retractable.

In order to improve the overturn prevention effect, it is preferable to provide an anti-slip member on the overturn prevention member.

As the non-slip material, a band made of a material having a non-slip function such as rubber or synthetic resin is attached to the outer periphery of the anti-tipping member, or a surface material made of the above-mentioned material is attached to the lower surface of the anti-tipping member. For example, a mode of installation can be exemplified.

Each of the above-mentioned struts is preferably formed so that a small-diameter pipe is slidably inserted into a large-diameter pipe so as to be expandable and contractable, and a cover material for covering the exposed small-diameter pipe and the lock mechanism is provided. As the cover material, use of an elastic bellows cylinder can be exemplified.

In this case, since the gap between the large-diameter pipe and the small-diameter pipe, the lock mechanism, and the like are covered with the cover material, there is no danger of fingers being pinched during use, folding, and assembly.
