たエレベーシヨンロツド３の外径に合うように調
節する等の手段を構じていた。 Conventionally, as shown in FIG. 2, a molded base 1 and an elevator made of, for example, aluminum alloy, are inserted into a through hole 2 provided with a key protrusion 2a provided in the base 1. An elevator device consisting of a rod 3 and a pinion gear is known, but the outer diameter of the elevator rod is, for example, 20Φ.
Since there is an unavoidable machining error of about ±0.3 per lot,
The inner diameter of the through hole 2 provided in the base 1 is set in advance to be large, and a means such as adjusting it to match the outer diameter of the elevation rod 3 given by an adjustment ring (not shown) is constructed. I was there.

で問題を生ずる場合が多々あつた。 In addition, in the conventional model, a keyway 3a was provided in the elevation rod 3, and a rack was carved directly on the outer periphery of the rod 3, so the wall thickness of the rod 3 did not need to be made thicker. Therefore, there is a waste of material, and the wall thickness of the part where the rack is provided becomes extremely thin, or the tooth groove sometimes penetrates the meat part, which causes problems in terms of strength. There were many cases where this occurred.

を提供せんとするにある。 The purpose of this invention is to be able to easily accommodate errors in the outer diameter of the elevation rod without using adjustment rings, etc.
It is an object of the present invention to provide an elevation device for a camera tripod that minimizes waste of materials and does not cause problems in terms of strength.
以下にこの考案を図面に示した一実施例に基づ

９ａを有するピニオンギア９と噛合している。
尚、１０はエレベーシヨンロツド７の締着手段で
ある。 This invention will be explained in detail below based on one embodiment shown in the drawings.
In the figure, a base 5 on which the legs 4, 4 are pivoted is provided with a through hole 6 having a groove 6a in the axial direction, and a convex groove in the longitudinal direction of the outer circumference of the through hole 6. The elevation rod 7 provided with a groove 7a is inserted with the protrusion 7a fitted into the groove 6a. A rack 8 is carved into this protruding portion 7a, and meshes with a pinion gear 9 having a handle 9a attached to the base 5.
Note that 10 is a fastening means for the elevation rod 7.
したがつて、貫通穴６の内径を予じめ小さく選
定しておけば、従来のもののようにキー突起がな
いのでこれが邪魔になることがなく、出来上つて
来たエレベーシヨンロツド７の外径に合わせてこ
れを容易に拡張することができ、従来のもののよ
うに調節リングを用いなくとも、ガタの生じない
取りつけを行うことができるものである。 Therefore, if the inside diameter of the through hole 6 is selected to be small in advance, it will not get in the way since there is no key protrusion unlike the conventional ones, and the outside of the completed elevator rod 7 can be easily removed. It can be easily expanded according to the diameter, and it can be installed without play without using an adjustment ring as in the conventional case.
また、エレベーシヨンロツド７それ自体に従来
のようにキー溝を設けてなく、さらに外周部より
直接にラツクを刻設してもないので、該エレベー
シヨンロツド７の肉厚を従来のもののように厚く
しなくとも支障は生ぜず、必要にして充分な強度
を保有することができ、材料を大幅に節約できて
いる。 In addition, unlike conventional models, the elevation rod 7 itself is not provided with a keyway, nor is a rack carved directly from the outer periphery. Even if it is not made as thick as this, there is no problem, it can maintain sufficient strength as required, and material can be saved significantly.
さらに、ラツク８を設けた凸条部７ａが凹条溝
６ａに嵌入し、そのまま滑りキーとなるので、わ
ざわざこれを設ける必要もなくなつた。 Further, since the protruding portion 7a provided with the rack 8 fits into the concave groove 6a and serves as a sliding key as it is, there is no need to take the trouble to provide this.
以上詳細に説明したようにこの考案は、簡単な
構成でエレベーシヨンロツドの持つ固有の外径誤
差を容易に吸収調節できると共に、材料の節約と
なり、さらに組立も極めて容易になるという作用
効果を奏し得る。 As explained in detail above, this invention has the effect of easily absorbing and adjusting the inherent outer diameter error of the elevation rod with a simple structure, saving materials, and making assembly extremely easy. It can be played.
