大きな作業を必要としていた。 The stilts, which can be used to fix a step on a pole at any desired position, fix the step on the pole via a locking member.
Conventional stilts have a step stool screwed onto this locking member,
A step stool was fitted onto the locking member and then pressed into place by tapping. In the case of screw-on devices, the threaded top of the locking member would become distorted or crushed after being removed and fixed many times while standing on the step stool. In addition, when fitting by tapping, not only do you need metal fittings such as a hammer, but you also have to use a large amount of force to remove the ball due to the troublesome work of tapping it. I needed it.
本考案の目的はこれらの問題を解決し、強い強
度をもつ係止部材を提供し、ワンタツチで踏台を
ポールに固定できる竹馬を提供することにある。 The purpose of the present invention is to solve these problems, provide a locking member with strong strength, and provide a stilt that can fix a step stool to a pole with a single touch.
以下本考案の構成を図示の実施例に基づいて説

設けられている。 1 is a pole and 2 is a step stool. Reference numeral 3 denotes a locking member, which is fitted in an insertion hole 4 so as to be movable up and down relative to the pole 1. The pole 1 is connected to this locking member 3
The outer surface is roughened to increase friction. Reference numeral 5 denotes a fitting portion of the locking member 3, which is composed of eight semicylindrical ridges 6, with troughs 7 formed between the ridges 6. This fitting portion 5 has a tapered shape whose diameter increases as it goes downward. Reference numeral 8 denotes the base of the locking member 3, which has a larger diameter than the fitting portion 5, and has a handle 9 projecting outward. Reference numeral 10 is a relief portion, for example, a slit, which is provided so as to reach the lower end of the base portion 8 on the opposite side of the locking member 3 from the handle 9.
It is designed to provide an escape when compressed. Reference numeral 11 denotes a groove, which is provided on the side of the insertion hole 4 of the fitting part 5, and when the fitting part 5 is compressed,
The individual peaks 6 correspond elastically to prevent plastic distortion. Numerals 12 and 12 are protrusions, which are provided at opposite positions at the upper end of the peak 6 of the fitting portion 5.

４までの突起１２の通路のはたらきをしている。 Reference numeral 13 denotes a fitting hole, which is provided at the base end of the step stool 2, into which the fitting portion 5 is fitted. This fitting hole 13 is also tapered so as to fit snugly with the fitting part 5, and has a diameter smaller than that of the base part 8. Guide parts 14, 14 are carved on the inner surface of the insertion hole 13, and the protrusions 12, 12 of the insertion part 5 fit into and slide. This guide portion 14 has a gentle spiral shape, and as the protrusion 12 is inserted along the guide portion 14, the insertion portion 5 is also pulled into the insertion hole 13. 15, 15 are communicating grooves, which extend from the lower end of the insertion hole 13 to the guide portion 1.
It serves as a passageway for the protrusions 12 up to 4.

変形によつて吸収することができる。 To fix the step stool 2 to the pole 1, insert the fitting part 5 of the locking member 3 into the fitting hole 13 so that the protrusion 12 matches the communication groove 15, and insert the handle 9 approximately as shown by the chain line in the figure. Rotate 90 degrees. At this time, the protrusion 12 enters along the spiral guide portion 14 through the communication groove 15, as shown by the dashed line in the figure. Therefore, the tapered fitting portion 5 is tightened by the tapered fitting hole 13, and the locking member 3 tightly tightens the pole 1, which has a rough outer surface, so that the locking member 3 and the step stool 2 can be easily moved. It will no longer move up and down. stepping stone 2
To remove it, simply turn the handle 9 of the locking member 3 in the opposite direction and pull it out downward. In this way, you can easily fix or remove the step stool with just one touch. Further, the fitting portion 5 of the locking member 3 has a ridge portion 6.
and a groove 7, and a groove 11 is provided on the inside, so that even when the step stool 2 is fixed or a load is applied to the step stool 2, the fitting portion 5 can elastically cope with this load and will not collapse. do not have. In addition, even if a large load is applied to the step stool 2, the outer surface of the pole 1 is rough, so the locking member 3 will not slip downward, and this load will be absorbed by the elastic deformation of the fitting portion 5 as described above. Can be absorbed.

きる。 Note that instead of making the outer surface of the pole 1 rough, the outer surface of the pole 1 may be made smooth and a rubber gasket may be attached to the inner surface of the insertion hole 4 of the locking member 3, or a large number of suction cups may be provided. Even in this manner, the locking member 3 can be securely fixed to the pole 1.
