を参照に詳述すると次の通りである。[Detailed Description of the Invention] The present invention relates to a foldable step stool that can be folded into a flat plate shape for convenient storage, and its structure will be described in detail with reference to the accompanying drawings as follows.
前脚枠ａを左前脚杆１と右前脚杆２と上下の横
桟杆３，１４とで形成し、後脚枠ｂを同じく左後
脚杆４と右後脚杆５と上下の横桟杆１１，１３と
で形成し、この前脚枠ａと後脚枠ｂとを側面より
見てＸ字状に配し、この左前脚杆１、左後脚杆４
と右前脚杆２、右後脚杆５の交叉部を枢着軸７に
より枢着し、この前脚枠ａの上方の横桟杆３に上
踏板８の後端部を枢着し、後脚枠ｂの下方の横桟
杆１３に下踏板１２の後端部を枢着し、この上踏
板８、下踏板１２の両側壁前部寄りに後脚枠ｂの
上方の横桟杆１１と前脚枠ａの下方の横桟杆１４

成し、更に上踏板８の両側壁後部寄りに前脚枠
ａ、後脚枠ｂを折り畳んだ時に後脚枠ｂの上方の
横桟杆１１に着脱自在に係止する係止切欠溝１６
を形成する。 The front leg frame a is formed by the left front leg rod 1, the right front leg rod 2, and the upper and lower horizontal crosspiece rods 3, 14, and the rear leg frame b is formed by the left rear leg rod 4, the right rear leg rod 5, and the upper and lower horizontal crosspiece rods. 11 and 13, and the front leg frame a and the rear leg frame b are arranged in an X shape when viewed from the side, and the left front leg rod 1 and the left rear leg rod 4 are arranged in an X shape when viewed from the side.
The intersection of the right front leg lever 2 and the right rear leg lever 5 is pivoted by a pivot shaft 7, and the rear end of the upper tread plate 8 is pivoted to the horizontal bar 3 above the front leg frame a. The rear end of the lower tread plate 12 is pivotally connected to the lower horizontal bar 13 of the frame b, and the upper lateral bar 11 of the rear leg frame b and the front leg Lower horizontal bar 14 of frame a
Locking grooves 10 and 15 are formed for detachably locking the upper tread plate 8, and when the front leg frame a and the rear leg frame b are folded toward the rear of both side walls of the upper tread plate 8, the upper horizontal bar of the rear leg frame b is formed. A locking notch groove 16 that is removably locked to 11
form.
図面の上踏板８、下踏板１２は周囲に壁を有
し、上面にスリツプ防止板９を止着している。 The upper tread plate 8 and the lower tread plate 12 in the drawings have a wall around them, and a slip prevention plate 9 is fixed to the upper surface.
図面は枢着軸７から上端部までの距離を、左右
前脚枠１，２の方が左右後脚杆４，５よりも長く
設定して、折り畳んだときに平板状に折り畳まれ
るようにしている。 In the drawing, the distance from the pivot shaft 7 to the upper end is set longer for the left and right front leg frames 1 and 2 than for the left and right rear leg levers 4 and 5, so that when folded, it is folded into a flat plate shape. .
図中１７はキヤツプてある。 In the figure, 17 is captured.
従来の折り畳み出来る踏み台は、特開昭52−
46971号公報で示すものであるが、折り畳んだ際
に脚が再び解放することを防止する固定機構が非
常に複雑であり、それだけ使用しづらい上に、そ
れだけ製作コストも高くなる欠点があつた。 The conventional foldable step stool was developed in Japanese Patent Application Laid-Open No. 1973-
The mechanism disclosed in Japanese Patent No. 46971 has the disadvantage that the fixing mechanism that prevents the legs from being released again when folded is very complicated, which makes it difficult to use and increases the production cost accordingly.
本考案は、かかる欠点を解決したもので、簡単
な固定構造にしてワンタツチで固定することの出
来る折畳式踏み台であつて、上述のように構成し
たから前脚枠ａと後脚枠ｂとを枢着軸７を支点に
して回動すると側方より見てＸ字状に開脚した
上、次に上踏板８を横桟杆３を中心に回動させて
係止切欠溝１０を横桟杆１１に係止すると上踏板
８は横桟杆３，１１とによつて水平支持される。 The present invention has solved this drawback, and is a folding step stool with a simple fixing structure that can be fixed with one touch.Since it is constructed as described above, the front leg frame a and the rear leg frame B are connected to each other. When the pivot shaft 7 is rotated as a fulcrum, the legs are opened in an X-shape when viewed from the side, and then the upper tread plate 8 is rotated around the horizontal bar 3, and the locking notch 10 is aligned with the horizontal bar. When engaged with the rod 11, the upper tread plate 8 is horizontally supported by the horizontal beams 3 and 11.
そして下踏板１２も横桟杆１３を支点にして回
動して係止切欠溝１０を前脚枠ａの横桟杆１４に
係止すると下踏板１２は横桟杆１３，１４とによ
つて水平支持されて第１、２図に示すように上踏
板８と下踏板１２とがＸ字状に開かれた前後脚枠
ａ，ｂの上下２段に水平架設された状態に簡単に
組み立てられることになる。 When the lower tread plate 12 also rotates about the horizontal bar 13 and locks the locking notch groove 10 to the horizontal bar 14 of the front leg frame a, the lower tread plate 12 is leveled by the horizontal bar 13 and 14. When supported, the upper tread plate 8 and the lower tread plate 12 can be easily assembled horizontally in two stages, upper and lower, of the front and rear leg frames a and b opened in an X-shape, as shown in FIGS. 1 and 2. become.
この場合、前脚枠ａと後脚枠ｂとはその交叉部
左右に於いて枢着軸７により止着されると同時に
上踏板８と下踏板１２とが前脚枠ａと後脚枠ｂと
の開いた開放度を規制固定するから荷重に対する
強度は充分なものとなり、丈夫で安心して使用出
来る踏み台になる。 In this case, the front leg frame a and the rear leg frame b are fixed to each other by the pivot shaft 7 on the left and right of their intersection, and at the same time the upper tread plate 8 and the lower tread plate 12 are connected to the front leg frame a and the rear leg frame b. Since the degree of opening is regulated and fixed, it has sufficient strength to withstand the load, making it a sturdy and safe stepping stone.
また、本踏み台を使用した後に収納する場合に
は、上記した組み立てと逆の手順を行う事により
容易に折り畳みをなし得て、第３図に示すような
コンパクトな平板状に折り畳み得ることになる。 Additionally, if you want to store this step stool after using it, you can easily fold it up by performing the assembly procedure in reverse order as described above, and it can be folded into a compact flat plate shape as shown in Figure 3. .
この場合、第３図に示すように上踏板８の係止
切欠溝１６が後脚枠ｂの横桟杆１１に係止して、
折り畳み状態が固定されるから前脚枠ａ、後脚枠
ｂは外力を加えない限り開くことがない。 In this case, as shown in FIG. 3, the locking notch groove 16 of the upper tread plate 8 locks with the horizontal bar 11 of the rear leg frame b,
Since the folded state is fixed, the front leg frame a and the rear leg frame b will not open unless external force is applied.
従つて、持ち運びも安全に行う踏み台になる。 Therefore, it becomes a safe stepping stone for carrying around.
その上、本案品は上記したように構造が簡単で
あるから扱いも容易となり、また製作も容易にし
て量産出来、それだけ本案品を安価に提供する等
秀れた実用上の効果を有するものである。 Moreover, as mentioned above, the proposed product has a simple structure, which makes it easy to handle, and it is also easy to manufacture and can be mass-produced, which has excellent practical effects such as providing the proposed product at a low price. be.
