Claims

[Scope of utility model registration request]

A plurality of cylindrical bodies 112 to li of a predetermined length whose diameters are sequentially arranged.
d are slidably fitted in the order of diameter to form a telescopic leg 11, and a leaf spring 17 and its free end are prevented from being compressed in the extended state at the rear end of each cylinder 11a to lld. In a camera tripod equipped with a stopper mechanism consisting of a protrusion 18 provided on the side, the cylindrical bodies 113 to 113 are fitted in sequence.
The through holes 1 are placed facing each other near the upper end of the holes 11d.
4 and 14, and has a projection 16a on the inside that fits into the through hole 14, and has an arcuate cross section. In the fitted state, fit into the gap between cylinders with different diameters,
A constriction part 13 is provided at the lower end of the cylinders 113 to IIC, the diameter of which is smaller by the thickness of the cylinder, and into which the cylinder with the smaller diameter can be slidably fitted. The wall thickness is approximately equal to the gap between the cylindrical bodies that fit into each other, and the through hole 15 into which the protrusion 18 of the leaf spring 17 fits is formed so that the stopper piece 16' is in contact with the inner step of the constricted part 13. A camera tripod characterized in that the diaphragm part 13 is located at the lower edge of the diaphragm part 13.
