場合を図示している。 In the drawing, an arc groove 6 is formed in the center of the presser plate 7,
The figure shows a case where a receiving cylinder 10 is attached to the lower side of the leg receiving frame 8, and locking protrusions 12 and 12' are provided at two places on the upper and lower inner surfaces of the vertical piece 11 of the mounting plate 3, and the upper locking protrusion 1
A through hole with a diameter slightly larger than the diameter of the auxiliary leg is bored near the distal end of the proctor plate 13 whose base end is fixed to the proctor plate 2, and the proctor plate 13 is provided so as to be able to rise and fall with respect to the mounting plate 3. A stopper plate 14 that is approximately the same size or slightly smaller than the protector plate 13, which is fitted onto the auxiliary leg 1 and whose base end is locked to the lower locking protrusion 12', has a stopper plate 14 that has a diameter larger than the diameter of the auxiliary leg. A through hole with a slightly larger diameter is drilled, and this stopper plate 14 is fitted onto the auxiliary leg 1 which is provided so as to be movable up and down with respect to the mounting plate 3.
A case is shown in which an anti-squeezing strip 15 wrapped around the auxiliary leg 1 is interposed between the stopper plate 14 and the lower piece of the mounting plate 3.

図中符号９は締付用ハンドルである。 Reference numeral 9 in the figure is a tightening handle.

る。 In the present invention, as described above, the channel frame 4 is horizontally protruded from the upper left and right sides of the mounting plate 3, and the tightening bolt 5 is screwed into the center piece of the channel frame 4. Attach the holding plate 7 and attach the mounting plate 3.
A leg support frame 8 for supporting the legs of a workbench, stepladder, etc. is attached to the lower part of the holder.The legs of the workbench, stepladder, etc. are inserted along the leg support frame 8, the bottoms of the legs are brought into contact with the leg support frame 8, and the channel frame is attached. When the tightening bolt 5 screwed into the center piece of 4 is tightened, the presser plate 7 is pressed by the tightening bolt 5 and fixed to the leg, making it easy to attach this product to the leg of a workbench, stepladder, etc. It will be possible.

この際例えば作業台や脚立などの脚が角脚の場

本案品が確実に固定されることになる。 At this time, for example, if the legs of a workbench or stepladder are square legs, the square legs are pressed and fixed by the inner surface of the channel frame 4 and the flat surfaces on both sides of the arcuate groove 6 of the holding plate 7.
Since it receives and fixes the bottom surface of the square leg, the product can be fixed to the square leg more reliably.

また作業台や脚立などの脚が丸脚の場合丸脚は

実に固定されることになる。 In addition, if the legs of a workbench or stepladder are round legs, a receiving cylinder 10 is provided below the upper holding plate 7, which is pressed and fixed by the inner surface of the channel frame 4 and the circular arc groove of the holding plate 7. Since the lower end of the round leg is fitted into and fixed to the receiving cylinder 10, the product can be fixed to the round leg more reliably.

このように本考案は作業台や脚立などの脚が角
脚であろうと丸脚であろうと確実に補助脚を固定
し得る秀れた作業台や脚立などの補助脚固定装置
となる。 As described above, the present invention provides an excellent auxiliary leg fixing device for a workbench, stepladder, etc., which can securely fix the auxiliary legs regardless of whether the legs of the workbench, stepladder, etc. are square legs or round legs.
