Intermediate plate for attaching cameras ο »the like»

on tripod heads

The invention relates to two-part intermediate plates for fastening of cameras, especially heavy film recording or television cameras or the like on stairiv heads, around those on the top plate to be able to set the camera in a desired position opposite the tripod head or the base plate.

Two-part intermediate plates of the type mentioned are already known become; they consist of a lower plate and an upper plate, one of which is guided in grooves in the other. The known intermediate plates are designed so that the two Panels can be moved against each other by hand »and then clamped together with the help of clamping screws have to be »In practice it has proven to be very inconvenient to move the usually very heavy camera by hand, once attached to the tripod head with the intermediate plate

TELEX: 018 4057

Stigt f is quite apart from the fact that the required clamping screws disturbed · In addition, it is very difficult in the known intermediate plates to make very small displacements of the two plates against each other, sometimes necessary igungsachse to the camera focus precisely in the desired position above the We of the tripod head "In practice, therefore, you are content with only approximate settings of the center of gravity and the rest of the weight compensation is carried out in the usual way by attaching weights"

The invention is based on the object of providing a two-part intermediate to create a lower plate of the type in question »when moving the camera attached to the top plate quickly * can be carried out easily and simply, even for the smallest amounts »

According to the invention, it is proposed to solve this problem » to improve a two-part intermediate plate known per se by the fact that in the upper as well as in the lower plate on the other facing side there is a groove in which a threaded spindle is located, which is in one of the two plates » in particular, the lower plate is axially immovable, and that the other of the two plates with a thread is equipped, which engages in the thread of the threaded spindle, so that when the threaded spindle rotates through this one plate opposite the other, the one with the threaded spindle connected, moved *

The screw is expediently positioned by means of an in one of the two plates is located in an annular groove the threaded spindle engages, axially immovable

The groove for receiving the threaded spindle advantageously has in one plate a semicircular profile on and is provided with a thread in its base, which engages in the thread of the threaded spindle «

In order to limit the displacement of the two mutually movable plates, a groove of limited length in one of the a bolt ο »like * screwed into the other plate protrude into both plates.

In Figures 1 to 3 of the drawing, the subject of the invention is shown on the basis of a particularly preferred embodiment »which is explained in more detail below * It zd-gen:

1 shows a plan view of the two-part intermediate according to the invention slab j

FIG. 2 shows a cross section through the intermediate plate according to FIG along the line II-II;

3 shows a longitudinal section through the intermediate plate according to FIG along the line III-III »

The intermediate plate according to the invention consists of the top plate

11 and the lower plate 12 »on the underside of the lower plate

12 there is a standard slot wedge 13 »which is inserted into a corresponding

ch.en.de Keyway on the top of the tripod head can be inserted
is"

The top plate 11 has a swallow on its underside.
tail guide 14, which is guided in a corresponding dovetail groove 15 on the top of the lower plate 12 ». Laterally parallel to the dovetail groove I5, on the mutually facing sides of the upper plate 11 and the lower plate 12, a groove 16 or 17 "the latter with a semicircular cross-section is arranged, in which the threaded spindle 18 is located. The threaded spindle 18 is on both of them Ends with a square 19 each
or «20, onto which a corresponding key can be attached» with the help of which the spindle can be turned *

The threaded spindle 18 is provided with a thread over its entire length? in its center it has an annular groove 21 in
which a wedge 22 fixed in the groove 16 engages in order to secure the spindle 18 against axial displacement «

The semicircular groove 17 on the underside of the top plate 11 is at least partially with an inwardly protruding threaded piece 23 provided, which engages in the thread of the spindle 18, so that upon rotation of the spindle 18 fixed in the lower plate 12, the upper plate 11 with the fixed, into the threaded spindle 18 engaging threaded piece 23 opposite the lower plate 12 is moved.

A further groove 2k can be provided laterally next to the groove 17, but this does not extend over the entire length of the intermediate plate. In this groove 24 the end of a bolt screwed 2% into the lower plate 12 protrudes through which the upper plate 11 is limited in its mobility in relation to the lower plate 12 *

In the middle of the top plate 11 is the threaded hole 26 for receiving the fastening bolt of the camera «

If necessary, the dovetail guide can also be used acting clamping wedge 27 should be provided »which by means of a pressure screw 28 arranged in the lower plate 13 against the dovetail guide 14 can be pressed or released «
