【発明の詳細な説明】
この発明はスタンド等に適用される支柱昇降装
置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a column lifting device applied to a stand or the like.
従来、たとえば実公昭39−26251号は、基柱に
支柱をスライド自在に嵌挿し、基柱に嵌着した環
状締付け具を締めることにより締付け金具を支柱
に圧接して固定するようにしていた。 Conventionally, for example, in Japanese Utility Model Publication No. 39-26251, a column is slidably inserted into a base column, and an annular fastener fitted to the base column is tightened to press and fix the fastener to the column.
しかしながら、環状締付け具を基柱のまわりに
回転する必要があるため、操作がしにくいという
欠点があつた。 However, since it is necessary to rotate the annular fastener around the base column, it is difficult to operate.
したがつて、この発明の目的は、昇降操作が容
易な支柱昇降装置を提供することである。 Accordingly, an object of the present invention is to provide a column lifting device that is easy to lift and lower.

より引出す。１１はキヤツプである。 A first embodiment of the stud to which an embodiment of the present invention is applied
This is shown in Figures 5 to 5. That is, in this stud, a fixed support 2 made of a pipe is erected on a base 1, and a slit 3 of a predetermined length is formed in the axial direction of the fixed support 2. A movable column 4 is slidably inserted into the fixed column 2, a notch 5 is formed at the lower end of the movable column 4, and a cam-shaped pressing member 6 is loosely inserted into the notch 5.
The pressing member 6 is rotatably supported by a horizontal shaft 7 in a plane parallel to the axial direction of the movable support 4, and one end of the horizontal shaft 7 is extended to protrude from the slit 3 of the fixed support 2, and a A lever 8 is provided. On the other hand, a lamp 9 is provided at the upper end of the movable column 4, and a power cord 10 is provided.
Pass it through the fixed column 2 and the movable column 4 and attach it to the base 1.
Pull out more. 11 is a cap.

９を任意高さに移動調整できる。 This stand moves the lamp 9 to a desired height by gripping the lever 8, and when the lever 8 is rotated, the maximum length 6a from the center of rotation of the pressing member 6 to the edge
presses the inner surface of the fixed column 2, and the movable column 4 is fixed. Further, when the lever 8 is rotated in the opposite direction, the portion 6a of the pressing member 6 is separated from the fixed support 2, so that the lamp 9 can be moved and adjusted to an arbitrary height.

作用効果がある。 As described above, the strut lifting device of the present invention includes a fixed strut with a slit formed in the axial direction, a movable strut that is slidably inserted into the fixed strut, and a movable strut that is provided at the lower end of the movable strut and has one end. a horizontal shaft protruding outward from the slit; a cam-shaped pressing member provided on the horizontal shaft and pressed against the inner surface of the fixed column by rotation; and a lever attached to the one end of the horizontal shaft. The preparation has the following effects.
すなわち、レバーを回動するように押すと水平
軸が回転して押圧部材が回動し、押圧部材の回動
により押圧部材が固定支柱の内面から離れるとき
可動支柱は固定支柱の任意の位置にスライド可能
となる。またレバーを反対向きに回動するように
押して押圧部材を反対向きに回動させ押圧部材を
固定支柱に押圧させると可動支柱が固定支柱に固
定される。このように、レバーを押すように回動
することにより可動支柱を昇降させることができ
るので、従来例と比較して操作が簡単である。 In other words, when the lever is pushed in a rotational manner, the horizontal axis rotates and the pressing member rotates, and when the pressing member separates from the inner surface of the fixed column due to the rotation of the pressing member, the movable column moves to an arbitrary position on the fixed column. It becomes possible to slide. Further, when the lever is rotated in the opposite direction to rotate the pressing member in the opposite direction and the pressing member is pressed against the fixed column, the movable column is fixed to the fixed column. In this way, the movable column can be raised and lowered by rotating as if pushing the lever, so the operation is easier than in the conventional example.
