Description

Tripod head for photographic tripods -------------------------------------- There are tripod heads for photographic tripods known, which consist of an upper and lower part, which are firmly connected to each other-z. B. screwed or riveted, the parting line between the two parts in the plane formed by the longitudinal center lines of the pivot axes for the tripod legs.

Tripod heads in this form have the disadvantage that they are not closed Have external shape and the pivot axes for articulation of the tripod legs are visible are.

To avoid this disadvantage, the innovation proposes a tripod head before, composed of an upper and a lower part, which are firmly connected to one another is and in which according to the invention the tripod legs either in the upper part or in the lower part of the head are articulated and the corresponding part of the tripod head is circular and the articulation parts for the tripod legs surrounds or covers to the outside.

This has the advantage that the tripod head can also be built in State forms a completely closed spatial shape, in which the articulation and Attachment of the tripod legs are no longer visible from the outside. Furthermore it will thus enabled the mounting parts for the tripod legs to be carried out easily and cheaply, because these are covered from the outside.

An expedient implementation of the proposed innovation exists in that the parting line between the upper and lower part of the tripod head around a certain distance from the longitudinal center lines of the pivot axes for the tripod legs is arranged offset up or down. More details of the proposal are described below with reference to the drawing.

Fig. 1 shows a longitudinal section through the tripod head, Fig. 2 shows a partial section along the line 1-1 through FIG.

The tripod head consists of the upper and lower part 1 and 2, the z. B. are screwed with three screws 3. The screws 3 are arranged sunk in the upper or lower part and centered. The hole or the associated Threads for the screws 3 are each arranged between the three tripod legs 4. The parting line between the upper and lower part expediently runs through a plane, by the distance A to the longitudinal center lines of the axles 5 for the articulation the tripod legs 4 is offset upwards or downwards.

In the illustrated embodiment, for. B. in the upper part 1 for the articulation of each tripod leg each two ribs 6 are arranged, which protrude downward over the parting line and to which the tripod legs 4 are initially attached to the pivot axes 5 during assembly. During the further assembly, the lower part 2 of the tripod head is pushed over the legs 4, the pivot axes 5 and the ribs 6. But it is also possible to articulate the tripod legs 4 in the same way in the lower part 2 and then to design the upper part 1 in such a way that the articulation of the tripod legs follows is covered on the outside.

In further training of the proposed innovation can in itself known Way be arranged in the tripod head a movable center column 11, to their Receiving a circular collar 8 on the upper and lower part 1, 2 is used; between the two collars 8 are guide parts for the center column 11-z. Legs Spacer sleeve 9 and, if necessary, guide rings made of felt or the like. One z. B. provided in the lower part 2 of the tripod head clamping device 10 is used to fix the center column.

The z. B. countersunk in the upper part 1 arranged screws 3 can with one attached to the end face of the upper part 1, e.g. B. glued annular Disc 7 to be covered.

According to the innovation, the two parts 1 and 1 forming the tripod head 2 manufactured in the pressure, injection or pressure molding process and ee is therefore except no subsequent cutting of the thread, which may be necessary mechanical processing of the two parts required more.
