Description

[Detailed Description of the Invention] The present invention relates to a folding structure for a platform-like body such as a table top, a bed floor, a chair seat, and a footrest.

Some of the above-mentioned table-like bodies have a structure in which the table-like body part can be folded into several parts so that the width of the top surface of the table-like body can be changed depending on the use. There are problems such as the structure being complicated or cumbersome to operate, or the presence of the folded platform making it inconvenient to use in the folded form.

Therefore, the present invention aims to solve these problems and provide a folding structure in a platform that is simple in structure, easy to operate, and can be used in a folded state without any problems. The gist of this is that one side edge of the movable side platform, which is also flat, is attached to the front edge of the flat fixed platform built on the support leg via a connecting member such as a hinge. The movable side platform can be folded onto the upper surface of the fixed side platform around the connection part of one side edge of the movable platform to overlap, and the movable platform is connected to the free end of the movable platform. The upper end of the leg that supports the shaped body in the unfolded state is rotatably pivoted, one end of the folding guide piece of the leg is rotatably pivoted to the lower end of the leg, and the guide The other end of the piece is a foldable platform which is pivotally attached to the lower part of the support leg of the stationary platform.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figures 1 to 3 show an embodiment in which the present invention is applied to a folding structure of a table top. , 2 is a movable platform which also constitutes a part of the table top A, and the fixed platform 1 is supported in a fixed state on supporting legs 3, 3 attached to the lower portions of both sides thereof. The table is made up of just that.

The movable platform 2 has one edge connected to the front edge of the stationary platform 1 by a connecting member 4 such as a hinge.
4, so that the movable platform 2 can be folded around the connecting portion so as to overlap the upper surface of the fixed platform 1. Further, 5, 5 is a leg piece that supports the unfolded movable platform in a substantially horizontal state;
6, 6 are guide pieces for determining and maintaining the lower end positions of the leg pieces 5, 5 and guiding the folding of the leg pieces 5, 5;
The base ends of the guide pieces 6, 6 are rotatably attached to the outer surfaces of the support legs 3, 3 in front of the lower ends of the support legs 3, 3, respectively, and the leg pieces 5, 5 are attached to the outer surfaces of the distal ends thereof.
The lower end portions are rotatably attached, and the upper ends of the leg pieces 5, 5 are rotatably attached to both side surfaces of the free end of the rotating platform 2, respectively.

Since this embodiment has the above configuration, in order to fold the movable platform 2 from the unfolded state shown in the embodiment drawings into a compact form, the free end side of the movable platform 2 must be lifted upward by hand. When the guide pieces 6, 6, which are connected by the leg pieces 5, 5, are rotated upward around the connecting part with the fixed side platform 1, the guide pieces 6, 6 become almost parallel to the movable side platform 2. , and rotates upward about its base pivot point (as shown by the dashed line in FIG. 2). And movable side platform 2
When rotated 180 degrees, the legs 5, 5 and the guide pieces 6, 6 are folded in a superimposed manner on the upper surface side of the fixed side platform 1, and the leg pieces 5, 5 and the guide pieces 6, 6 are folded at the rear edge of the outer surface side of the supporting legs 3, 3. and is housed in the lower edge (as shown by the two-dot chain line in FIG. 2). In this folded form, the back side of the movable platform 2 can be used as a table top.

Next, to unfold the movable platform 2, contrary to the above operation, simply rotate the movable platform 2 180° from the position indicated by the two-dot chain line in Fig. 2 to the position indicated by the solid line. The movable platform 2 is supported in an expanded state by the legs 5, 5 following the movable platform 2, and at the same time moves forward following the legs 5, 5. The lower end positions of the leg pieces 5, 5 are reliably maintained by the rotated guide pieces 6, 6, so that the movable platform 2 is stably and reliably supported in a horizontal state. be.

Although the drawings of this embodiment show a case in which the movable platform 2 in the unfolded state is in a horizontal state and the leg pieces 5, 5 are in a vertical state, they may be in an inclined state if necessary. Furthermore, the pivoting positions of the guide pieces 6, 6 can be arbitrarily set within a range that does not interfere with the rotation of the movable platform 2.

As explained in detail above, according to the present invention, not only can the folding and unfolding operations of the movable side platform be performed extremely easily and quickly by only rotating the movable side platform by 180 degrees, but also the leg pieces and The guide piece automatically follows the rotation of the movable platform, and in the folded state it can be stored in a compact form, and in the rotating state it can support the movable platform in an extremely stable state. Moreover, even in the folded state, the movable side platform is superimposed on the upper surface side of the fixed side platform, so there is no problem in using it in the folded state, and furthermore, it can be used as needed. There are advantages such as the ability to use the back side of the movable platform as it is as a table top.
