Description

tripod head

The invention relates to a tripod head with ball joint, the one in a

Bearing housing pivotally and rotatably mounted ball joint has.

Tripod heads with ball joint are preferably used for photographic cameras in order to pivot the position of the camera in three axes and can be fixed by pressing a clamping lever. Such tripod heads can be used for other optical devices, such as video and movie cameras and telescopes.

Increasingly, triggered by the development of

Digital cameras, photographic cameras also used as video cameras, in which case the free pivoting about three axes is undesirable. Video and movie cameras are preferably pivoted and / or rotated only about two axes. The same applies to the production of panoramic shots.

From DE 198 39 461 C1, a tripod head with a ball joint is known in which one of the three pivot axes can be fixed by a clamping device. A disadvantage of this solution is that the clamping position with increased effort is surmountable. Overcoming the clamping position is favored for example by high mass of the optical device placed on the tripod head. In DE 10 2013 004 952 A1 a tripod head of the type mentioned is described in which in the tripod head housing a switchable locking device is arranged, which is switchable from a release position into a blocking position and engages in the blocking position in a arranged at the equator of the ball joint locking recess ,

Object of the present invention is to provide an improved tripod head, which is characterized by an easy and intuitive operation.

According to the invention, this object is achieved with the subject matter of claim 1. It is proposed a tripod head, with a in one

Tripod head housing arranged ball joint, which includes a joint socket and a pivotally mounted in the joint socket about three pivot axes ball joint. At one pole of the ball joint is a connection piece with a

Attachment thread arranged for connection of an optical device, and on which the joint ball remote from the bottom portion of the tripod head housing is provided a tripod thread for connecting the tripod head to a tripod. The three pivot axes form an x-y-z coordinate system whose center coincides with the center of the ball and whose y-axis is aligned with the longitudinal axis of the tripod thread. So the ball joint in all

Directions are pivoted. On the tripod head housing a switchable locking device is arranged, which can be switched from a release position into a blocking position. The locking device comprises a locking button arranged on the tripod head housing which, when actuated, displaces a locking pin displaceably mounted in an equatorial through hole of the ball joint into a locking position. The locking pin can then be moved by pressing the locking button again into a release position. For the blocking pin, for example, a so-called ballpoint pen mechanism or a Have push-pull mechanics. Alternatively, a release button can be arranged on the tripod head housing to move the locking pin from the blocking position to a release position.

The tripod head has the advantage that an easy and intuitive operation is possible by the one button or the two provided switching buttons. The object of the invention is further achieved by the subject matter of claim 2. It is a tripod head with a arranged in a tripod head housing ball joint, which includes a joint socket and a pivotally mounted in the joint socket about three pivot axes ball joint, proposed, wherein at one pole of the ball joint a connection piece with a

Fixing thread for connection of an optical device is arranged and on which the joint ball remote from the bottom portion of the tripod head housing, a tripod thread or a tripod screw is provided, wherein the three

Longitudinal axis of the tripod thread is aligned, wherein on the tripod head housing a switchable locking device is arranged, which is for fixing a

Pivoting movement of the joint ball is switchable about at least one pivot axis from a release position into a blocking position, wherein it is proposed

in that a clamping device is arranged on the tripod head housing which has at least one clamping knob and / or a clamping lever for fixing and / or releasing a pivoting movement of the joint ball, and the at least one clamping knob and / or the clamping lever acts or act on the joint socket such that the joint socket clamps and / or releases the joint ball in the equatorial region. The equatorial region preferably refers to the equatorial region of the joint ball. It denotes the horizontally oriented area of the

Ball joint with the largest diameter. Even when the joint ball is pivoted, the orientation and disposition of the equatorial region remain the same since the center of the joint ball lies within the equatorial region.

The proposed tripod head has the advantage that the joint ball maintains its position in the transition from a release division into a clamping position and does not migrate upwards, as is the case with clamps which act on the bottom of the joint ball.

It can be provided that the locking device comprises a locking pin displaceably mounted in an equatorial through-hole of the ball joint, which engages in a locking button arranged on the tripod head housing

In the release position, the joint ball can be pivoted in any direction. Thus, for example, a camera or a camera on the condyle for a particular image motif can be pivoted as desired. In the blocking position, however, is a pivoting of the ball joint to a

Pivot axis or fixed around two pivot axes. Thus, the

Swivel range of the joint ball limited. The tripod head is therefore particularly suitable for video and film cameras as well as for the production of panoramic images, for which a tripod head is preferred, which can preferably be pivoted and / or rotated only about one or two axes. It can be provided that the lock button is designed as a latching push button, which is switchable by key operation from a release position into a blocking position.

1 shows a tripod head 1 with a ball joint which comprises a joint ball 1 1 and a joint socket 13 arranged in a tripod head housing 12. The joint ball 1 1 is in the joint socket 13 about three mutually perpendicular axes x, y, z pivotally. This x-y-z coordinate system is related to the socket 13, with the center of the hollow spherical inner wall of the socket 13 coinciding with the center of the x-y-z coordinate system.

The ball joint 1 1 has a cylindrical connecting piece 14 with an internal thread, which serves as a fastening thread for example a

Clamping plate device 2 is formed with a pivoting arm 3 (see Fig. 1 a). The tripod head housing 12 has a support recess 12a for the

Connecting piece 14 which is formed so that the connecting piece 14 can be brought into a position in which its longitudinal axis coincides with the x-axis of the tripod head 1. The ball joint 1 1 is about a clamping lever 15 which is rotationally rigidly connected to a clamping screw 15s, or alternatively with a clamping knob 16 against the inner wall of the socket 13 so pressed that a frictional engagement between the spherical surface and the inner wall of the socket 13 is formed the ball joint 1 1 fixed in the socket 13. The clamping knob 16 allows the adjustment of the clearance between the socket 13 and the ball joint 1 1, so that the adjustability of the ball joint 1 1 between smooth and stiff is adjustable. As can be seen in FIGS. 2 and 3, the tripod head housing 12 has a

Clamping slot 12s, in which an elastic intermediate layer 12z is inserted. Upon actuation of the clamping lever 15 from a release position into a clamping position, the width of the clamping slot 12s is reduced and so in the

tripod head housing 12 formed joint socket 13 compressed, the joint ball 1 1 is clamped equatorial. The ball joint 1 1 retains due to the equatorial clamping in the clamping position in the transition occupied by the release position and does not migrate upwards, as is the case with clamps acting on the bottom of the ball joint, the case. The drawn in Fig. 3 arrows, which point to the center of the ball joint 1 1, symbolize the generated by the clamping screw 15s

Equatorial clamping forces.

In the embodiment shown in FIG. 1, the tripod head 1 is arranged on a tripod head receptacle 17 which can be screwed onto a tripod by means of a tripod screw (tripod screw and tripod are not shown in FIG. 1). At the top of the tripod head receptacle 17, an annular receptacle for the tripod head 1 is formed, whose longitudinal axis is aligned with the threaded axis of the stand nut 17s and the y-axis. The tripod head 1 is with a

Clamping knob 18 on the tripod head receptacle 17 detectable, so that the tripod head 1 is not tightened with the clamp button 18 in the tripod head receptacle 17th

is rotatable.

The tripod head 1 also has a locking device 19 (see FIGS. 3 to 12). The locking device 19 can be switched by a locking button 191 in a blocking position in which the ball joint 1 1 is only pivotable about the z-axis. Thus, the tripod head 1 can be used as a video head. The locking device 19 is connected through a Release button 192 switchable to a release position in which the joint ball 1 1 is pivotable about all three axes of the xyz coordinate system. As shown in Fig. 4, both the lock button 191 and the release button 192 are formed with a fastening thread formed in two

opposite threaded holes 12 g of the tripod head housing 12 can be screwed. It is thus possible to provide blanking plugs instead of the two switching keys 192, 193 if the blocking function of the tripod head 1 is not required.

The locking pin 193 is guided in a through hole 1 1d of the ball joint 1 1. The longitudinal axis of the through hole 1 1 d coincides with the x-axis of the x-y-z coordinate system and is in the blocking position of the locking device 19 at the same time the pivot axis of the ball joint 1 1.

The locking pin 193d has a perpendicular to the longitudinal axis formed

Through hole 193d, which is aligned in the assembled state of the tripod head 1 in the release position of the locking device 19 with a through hole 1 11, which the ball joint 1 1 and the connector 14 in their

Longitudinal axes passes through. The through hole 1 11 has in its upper

End portion of an internal thread, which is designed as a fastening thread for the clamping plate device 2 shown in Fig. 1 a. When the joint ball 1 1 is aligned so that said longitudinal axes with the y-axis of the

Tripod head 1 coincide, a pin key is inserted into the through hole 1 11, which makes it possible to operate the tripod screw (see Fig. 8 to 14).

The locking pin 193 has an annular groove for receiving an O-ring 193o, the friction of the locking pin 193 of the through hole 1 1 d the

Ball joint 1 1 led locking pin 193 so he increased his by the Lock key 191 or by the release button 192 brought about

Safely retains shift position. The release button 192 facing end portion of the locking pin 193 jumps back relative to the diameter of the locking pin 193 and has a

Entry chamfer, which facilitates the insertion of the locking pin 193 described in the lower in Fig. 10 and 1 1 in the release button 192. 6 shows the structure of the lock key 191. The lock key 191 includes a key button 191k, a lock switch pin 191s, a key housing 191g, and a return spring 191f.

In the embodiment shown in Fig. 8 to 14, the key button 191 k and the blocking switch pin 191 s are formed integrally. The cup-shaped

Key head 191 k engages over the bottom of the key head 191 k facing end portion of the Sperrschaltstifts 191 s. Between the inner wall of the

Key button 191 k and the blocking switch pin 191 s is a receiving space for the formed as a conical helical spring return spring 191 f formed. The the key head 191 k remote from the end portion of the Sperrschaltstiftes 191 s is formed as an inlet cone.

The front portion of the key housing 191 g, which faces the key top 191 k, is formed as a cylinder with key surfaces. The rear portion of the key housing 191 g is formed with an external thread and jumps back with respect to the front portion. The key housing 191 k has an axial through hole in which the Sperrschaltstift 191 s is performed.

The blocking switch pin 191 s has an annular groove in its middle section

Receiving a spring ring 191 r on. The spring ring 191 r acts with a

Release recess 191 gf and a locking recess 191gs together, the spaced from each other in the inner wall of the key housing 191 g are formed as annular recesses. Fig. 7 shows the structure of the release button 192. The release button includes a release button 192k, a release button 192s

Release key housing 192g and a release return spring 192f.

In the embodiment illustrated in FIGS. 8-14, a front is recessed from the diameter of the release switch pin 192s

End portion in a in the bottom of the cup-shaped key top 192nd

trained through hole pressed or glued. Of the

Release key button 192k overlaps the end portion of release key 192s facing the bottom of release key button 192k. Between the inner wall of the release button 192k and the release switch pin 192s, there is formed a receiving space for the tapered coil spring

Release return spring 192f formed.

The front portion of the release key housing 192g, which is the

Release button 192k facing is formed as a cylinder with key surfaces. The rear portion of the release key housing 192g is formed with an external thread and jumps back against the one portion. The key housing 192g has an axial through hole 192gd, and the front portion of the through hole 192gd formed in the front portion of the release key housing 192g has a smaller diameter than the portion formed in the rear portion of the release key housing 192g. In both sections of the through-hole 192gd, the blocking switch pin 191s is guided. The rear portion of the release switch pin 192s facing away from the release button knob 192k has one opposite to the one

Diameter of the release switch pin 192s projecting annular

Stopper 192 a, which also forms a guide body, which is guided in the rear portion of the through hole 192 gd. The the release button button 192k facing end surface of the stopper 192sa forms the abutment surface, which prevents the release switching pin 192s due to the spring force of

Release return spring 192f is pulled out of the release key housing 192g. To assemble the release button 192, the release switch pin 192s is inserted into the release button housing 192g as far as it will go

Release return spring 192f is inserted into the release button 192k, and then, under bias of the release return spring 192f, the release button 192s is fitted with the release button 192k and firmly connected, as stated above.
