Description

  The present invention relates to a folding step chair.

  In general, a step chair is used, for example, when taking a book stored in a high position on a bookshelf in a library, or when you have finished reading a book, and can also be used as a chair when reading a book. .

  Also, it is often used in homes, for example, kitchens, storerooms, bathrooms, etc., when you take away various items at high places. With this step chair, you can safely and easily take out things. Or you can get away.

  However, since the conventional step chair requires a considerably large storage space when not in use, it is not excellent in practicality and convenience.

  Therefore, the present invention has been devised, and an object thereof is to provide a folding step chair that can greatly reduce the storage space when not in use.

  Claim 1 of the present invention includes a left frame comprising a first support rod and a second support rod which are provided on both lower sides of a joint member pivotally supported in an upward direction, and the left frame. A first support rod and a second support rod, which are arranged in parallel at a predetermined interval and have a joint member rotatably supported in combination with the joint member, and are provided on both lower sides of the joint member. A right frame comprising a support rod; a pivot shaft provided between a first support rod of the left frame and a first support rod of the right frame; a second support rod of the left frame and a second support of the right frame Positioning rod provided in parallel with the rotation shaft between the rod, a pivot portion provided on the rotation shaft, a tread plate having a concave portion provided on the positioning rod, and a plate having two ends In the body I, one end is pivotally to the positioning rod, characterized in that it has at least one interlocking plate and the other end is pivoted between the recess and the connecting part of the footboard.

  According to a second aspect of the present invention, in the folding step chair according to the first aspect, at least one fixing member for preventing the pivot shaft from falling off is provided outside the pivot shaft in the pivot portion. It is attached.

  A third aspect of the present invention is the folding step chair according to the first aspect, wherein the first support rod and the end of the second support rod in the left frame and the first support rod and the second support rod in the right frame. A non-slip cap is attached to each end of each.

  The present invention solves the above-described problems, and stores the tread plate while rotating it around the rotation shaft, and at the same time folds the first support rod and the second support rod of the left frame and the right frame. Thus, the volume of the step chair can be reduced, so that the storage space can be greatly reduced.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the following Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the following Example itself at all.

  1 is an exploded perspective view showing an embodiment of a folding step chair according to the present invention, FIG. 2 is a perspective view of a folding step chair according to the present invention, and FIG. 3 is a folding view according to the present invention. FIG. 4 is a side perspective view of the folding step chair according to the present invention, and FIG. 5 is a side perspective view illustrating a developed state of the folding step chair according to the present invention. FIG. 6 is a side perspective view showing a folded state of the folding step chair according to the present invention.

As shown in FIGS. 1, 2, and 3, the folding step chair according to the present invention includes a joint member 13 that pivotally supports the first support that is provided on both lower sides of the joint member 13. A left frame 10 including a rod 11 and a second support rod 12 and a joint member that is arranged in parallel with the left frame 10 at a predetermined interval and is rotatably supported in combination with the joint member 13 above. And a right frame 20 including a first support rod 21 and a second support rod 22 provided on both lower sides of the joint member 23.
A rotation shaft 30 is provided between the first support rod 11 of the left frame 10 and the first support rod 21 of the right frame 20, and the second support rod 12 of the left frame 10 and the first support rod 21 of the right frame 20. Between the two support rods 22, a positioning rod 40 is provided in parallel with the rotation shaft 30.

  And it is a plate body which exhibits the substantially rectangular shape which has the 1st long side 53, the 2nd long side 54, and the two short sides 55 and 56, and the two fixing members 70 are on the bottom face of the vicinity of the 1st long side 53. A pivot part 51 for pivoting the pivot shaft 30 is formed by screwing with a screw at an appropriate interval, and a recess part 57 is formed between the two fixing members 70 in the first long side 53. And a tread plate 50 formed with a recess 52 for providing the positioning rod 40 on the bottom surface in the vicinity of the second long side 54.

  In addition, on both sides of the step 50, an elongated plate-like interlocking plate 60 having a large end 61 and a small end 62 is disposed. The large end portion 61 is formed with a through hole 611 for penetrating the positioning rod 40, and the small end portion 62 is formed with a screwing hole 621. The plate 60 is pivotally supported by screwing the plate 60 between the concave portion 52 of the two short sides 55 and 56 of the step plate 50 and the pivot portion 51 through the screw hole 621.

  Further, non-slip caps 80 are attached to the ends of the first support rod 11 and the second support load 12 of the left frame 10 and the ends of the first support rod 21 and the second support rod 22 of the right frame 20, respectively. Yes.

  As shown in FIG. 4, when using the folding step chair according to the present invention, the second long side 54 is moved in the direction of the positioning rod 40 while rotating the step board 50, and the step board 50 is moved. Is inserted into the positioning rod 40, and at the same time, the first support rods 11, 21 in the left frame 10 and the right frame 20 are opened by the joint members 13, 23 so as to be separated from the second support rods 12, 22. Since the foldable step chair according to the present invention can be developed, it can be used as a step or a chair.

  On the other hand, when storing as shown in FIGS. 5 and 6, the first support of the left frame 10 and the right frame 20 is provided by the joint members 13 and 23 while the tread plate 50 is rotated upward with the rotation shaft 30 as a fulcrum. If the rods 11 and 21 and the second support rods 12 and 22 are pulled and folded, the overall storage volume can be reduced, so that they can be stood beside a wall or a bookshelf, or stored in a space between furniture or a room. .

  Since the present invention has the above configuration, it can be easily expanded and folded, so that various spaces can be used efficiently.
