本発明は筒の嵌合により引伸ばし可能で、筒形部片より
成り、緊締装置によって固定し得る脚を有する三脚に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tripod having legs which can be stretched by fitting a tube, consist of a cylindrical piece, and can be fixed by means of a tensioning device.
この種の公知の三脚においては、それぞれの内側及び外

締装置は実質的に環状のローレットを有する緊締ナツト
より成り、との緊締ナツトが楔状の断面のリングを脚部
片の何れか一つに対して押圧させるようになっている。In known tripods of this type, the respective inner and outer cylindrical leg pieces are adjusted and fixed relative to each other by means of a tensioning device. Such a tightening device consists of a tightening nut with a substantially annular knurl, which causes a ring of wedge-shaped cross section to be pressed against one of the leg pieces.
このような二つの脚部片の相互の抑止方法は操作が面倒
で作動が確実ではない。This method of restraining the two leg pieces from each other is cumbersome to operate and is not reliable.
すなわち固定リングが充分強固に緊締されない場合には
二つの脚部片が互に滑動する恐れがある。This means that if the fixing ring is not tightened tightly enough, there is a risk that the two leg pieces will slip relative to each other.
その結果としてカメラを三脚に載置した時に一つの脚部
が引込められて三脚が倒れることになる。As a result, when the camera is placed on a tripod, one leg is retracted and the tripod collapses.

ならば二つの脚部片が互に回転するからである。これに
よって緊締レバーは三脚を引込める時に角度位置が定ま
らず、したがって操作が困難となる。For tripods in which the leg pieces are made from U-shaped profiles, clamping devices are known in which the restraint is performed in a particularly simple manner by means of a clamping lever. However, the legs of such open-sided U-shaped profiles are unstable to torsional stresses and are therefore disadvantageous compared to closed cylindrical profiles. But U
It is not possible to use the known clamping devices on tripods with shaped profiles, but on tripods with cylindrical leg pieces. This is because the two leg pieces rotate relative to each other. This causes the tightening lever to have an indeterminate angular position when retracting the tripod, thus making it difficult to operate.
本発明の目的は脚部が筒形の脚部片より成る三脚に緊締
レバーを有する緊締装置を組込み可能となすことである
。SUMMARY OF THE INVENTION An object of the present invention is to make it possible to incorporate a tightening device with a tightening lever into a tripod whose legs consist of cylindrical leg pieces.
上述の目的は、それぞれの内側の脚部片の外側面に少な

するようになすことによって達成される。The above-mentioned object has at least one longitudinal groove on the outer side of each inner leg piece, into which a block body attached to the inner side of the respective outer leg piece engages. This is achieved by doing as follows.
このようにして構成された三脚において筒の嵌合により
互に伸長可能の二つの脚部片が互に回転できなくなり、

ック体は有利な状態で緊締装置のある範囲にて外側の脚
部片の下端部に取付けられるのである。In the tripod constructed in this way, the two mutually extendable leg pieces become unable to rotate relative to each other due to the fitting of the tubes.
This makes it possible to incorporate a tensioning device with a known tensioning lever. A tripod constructed in this way is considerably simpler in construction and therefore cheaper and at the same time more stable. The tightening operation is simplified and reliability is increased. The block body is advantageously attached to the lower end of the outer leg in the region of the tensioning device.
本発明の特に有利な構成により、さらに内側の脚部片の
長手溝の上端部に対応するブロック体が取付けられる。According to a particularly advantageous embodiment of the invention, a corresponding block body is also attached to the upper end of the longitudinal groove of the inner leg piece.
このブロック体は三脚を引伸ばす時の制止部として役立

る。In order to improve the tightening action, each outer leg piece has projections mounted at angular intervals on its inner side in the region of the tightening device and opposite the tightening piece arranged on this tightening device. is provided. This results in a straight, parallel contact of the respective inner leg piece with the block body, which increases the stability of the tightening action.

脚部片が設けられるのである。Further details and advantages of the invention will be better understood from the following description of an embodiment illustrated in the accompanying drawings. In the tripod shown in FIGS. Legs that can be extended by fitting into the cylinder are swingably supported. These legs consist of a cylindrical leg piece 2.3 of substantially cylindrical cross-section, with a lower, smaller cross-sectional inner leg piece 2 in the upper outer leg piece 2 in the drawing. The pieces 3 are slidably fitted. For the sake of simplicity, in the illustrated embodiment the leg consists of only two leg pieces, but as a rule at least three suitably constructed leg pieces are provided.

で示されている。The two leg pieces of the illustrated leg are firmly fixed to each other by a known tightening device 4. This tensioning device 4 essentially consists of a shell which surrounds the lower end of the outer leg piece 2, in the interior of which a lever 5 is swingably mounted, which lever is moved inwards by means of a restraining part 6. The leg piece 3 of the outer leg piece 2 is pressed against the outer leg piece 2 (see FIG. 4). An elastic foot 7 is provided at the lower end of the inner leg piece 113. A hole 2A is provided at the upper end of the uppermost outer leg piece 2, through which a mounting bolt provided on the head 1 of the tripod is fitted. In the illustrated embodiment, the tripod has a central post 8 which is slidable in a guide IA of the tripod head l and whose position can be fixed in a conventional manner not shown. In FIG. 2, the same tripod as in FIG. 1 is shown with the lower leg piece 3 completely retracted into the upper leg piece 2.

A block body 11 corresponding to ' is provided. This block body 11 is fitted into a corresponding recess of the longitudinal groove 9. When the leg pieces 2 and 3, which slide by fitting in and out of each other, are fully extended, the block bodies 10 and 11 are in the fifth position.
They abut each other in the state shown in the figure and further prevent the leg pieces from being pulled out.

A lip-shaped protrusion 12 is provided on the inner surface, and the outer surface of the inner leg piece 3 is pressed against this protrusion along the range of the protrusion.
このことは緊締作用を良好にし、三脚の安定性を向上さ
せる。This improves the clamping action and increases the stability of the tripod.
