Tripod for photographic purposes

The invention relates to a tripod for photographic purposes with two vertical columns attached to a preferably mobile tripod base, along which a camera support is movable.

In known tripods of this type, the two vertical columns are arranged at some distance from one another and connected by the camera mount. The carrier insists

from an approximately horizontally running pipe that is attached to both Ends by means of sleeves is slidably mounted on the pillars and lockable. The bracket for the camera is on slidable on the horizontal camera support. The disadvantage of such tripods is that the camera is only about pivotable about a vertical axis through a relatively small angle otherwise either the lens and / or the ground glass will be shaded by one of the two pillars.

Tripods are also known in which the camera carrier ' is supported on a single column and protrudes from this. With such tripods, the individual column and the holder, which can be slid on it, is extremely stable if it is used for large cameras and optical benches should be suitable.

The invention is based on the object of creating a so-called studio tripod, which is relatively simple, easy to dismantle and yet extremely stable and allows a camera to be pivoted through a large angle.

This task is based on a tripod from the introduction mentioned type solved in that the camera carrier is designed as a cantilever arm in the direction of the connecting line

protrudes from both stand columns and its bracket includes both stand columns.

Such a tripod is on the one hand extremely stable, since it is made up of two pillars; on the other hand, it allows the camera to be pivoted at just as large an angle as one Single column stand.

According to a particularly advantageous embodiment of the invention, a camera holder is arranged on the boom arm is pivotable about the axis of the cantilever arm by means of a gear. The camera holder is on a housing attached, which includes the cantilever arm, and in the housing is preferably provided with a handwheel Rotatably mounted worm which is in engagement with a worm wheel fixedly connected to the cantilever arm. Of the The camera holder can be a normal tripod head, preferably a ball joint head.

According to a particularly advantageous embodiment of the invention the columns are releasably fastened in a foot part with three rollers, preferably with rollers at the ends Outriggers is provided, one of which extends in the direction of the cantilever arm. The foot part is with a

Clamping portion _s provided having two the diameter of the column adapted slotted holes, which can be clamped together by screws accessible from the outside. The slotted bores are advantageously widened conically at the upper edge and the columns have corresponding conical collars at the level of this edge. This design of the tripod according to the invention makes it possible to remove the columns very easily from the foot part or to insert them back into it, which is of great importance for the transport and storage of the tripod, which is bulky in itself.

At each end of the puss part there is a vertical one Axis rotatable roller is provided and a Peststellvorrichtung is present at at least one end. This Peststellvorrichtung advantageously consists of a stamp which can be displaced vertically downwards by means of a foot lever. The foot lever can be a rocker arm, which is connected to a cam which delimits a spiral is and acts on the stamp. The cam disk can have a recess in the area of its largest diameter, in which a correspondingly designed part of the stamp engages, whereby the stamp can be determined in the locking position. - -

In the stand according to the invention, two vertical columns 2 and 2 'are attached in a foot part 1, along which the holder 3 of a cantilever arm 4 can be displaced. The holder 5 comprises both stand columns 2 and 2 \ which can be displaced in corresponding recesses in this holder 3. Inside the columns are counterweights (not shown) which can be displaced in the vertical direction and which are connected to the holder via cables which are deflected by rollers located in the connecting part 5. To fix the holder at a certain height, a screw provided with a handwheel 6 is provided, the end of which can be pressed onto the column 2.

The cantilever arm 4 has one end 1n of a corresponding one Recess of the bracket 3 attached. At its other end it is surrounded by a housing 7 on which a ball joint head 3 is attached, in which a column 10 is vertically displaceable by means of a crank 9, which at the upper end a camera support plate 11 for the attachment of the camera 12 carries.

In the end part 13 of the housing 7 is one by means of a handwheel 14 rotatable screw mounted with a fixed with the cantilever arm 4 connected worm wheel is engaged. By turning the handwheel 14, the housing can 7 and thus the camera 12 can be rotated about the axis of the extension arm 4.

In order to be able to collapse the stand according to the invention for transport or storage in a very small space, the two columns 2 and 2 * are detachably connected to the foot part 1 according to a particularly advantageous development. For this purpose, a clamping part 15 * is located inside the foot part 1, which is provided with two slotted bores \ G and l6 ^f and which can be clamped together by two screws 17 and 17 ', which through openings l3 and l8 ^f in the housing of the foot part 1 are accessible. At the upper edge, the bores 16 and 16 ^{f have} conical extensions,

In the corresponding conical lugs 32 and 32 'on the two columns 2 and 2 ^{1 can be} inserted. By simply loosening the two screws 17 and 17 *, the two columns 2 and 2 'can be pulled out and placed on the foot part 1 for transport or storage.

In the foot part 1 there are three tubular arms 19, 19 'and 19 " attached in corresponding recesses. The two arms 19 'and 19 "can consist of a continuous tube exist. All three booms are provided at their ends with rollers 20, which are pivotable about a vertical axis 21, as well as Peststellvorrichtungen that an undesirable Prevent the tripod from moving.

The Pest control devices consist of one in a vertical Sleeve 22 displaceable punch 23j which has an elastic buffer 24 at its lower end and the by means of a pin 26 which is fixedly connected to its upper end and slidable in a longitudinal slot 25 of the sleeve 22 by means of a pin 26 which is fastened to a foot lever 27 Cam 28 can be displaced downward until it stands up on the floor 29 and, if necessary, the stand increases slightly. In order to lock the punch 23 in this position, the cam disk 28 is provided with a recess 30 provided, in the unlocked position is the Pin .26 on a nose 31 of the cam 28.
