Applicant claims priority under 35 U.S.C. § 119 of German Application No. 10 2018 009 279.9 filed Nov. 23, 2018, the disclosure of which is incorporated by reference.
The invention relates to an apparatus for mounting of a camera or other components, preferably a mounting for affixation of the camera or other components on moving objects, wherein the mounting is fastened to the moving objects using vacuum suction cups.
For the production of movie, television, video or advertising recordings, it is necessary to fasten the cameras used onto mountings or tripod heads, which can be pivoted in multiple axes.
In this regard, a pivoting function and a nodding function are known state of the art. The inclusion of a third axis (rolling axis) is also known, but it requires great technical effort for the production and operation of such apparatuses.
In this regard, pivoting of the mounting systems including the cameras can be carried out both manually and by means of different motor drives. Usually, stepper motors are used for this purpose, which are used by way of a rotation shaft and a control circuit for control of the pivoting/tilting function. The use of pulse counters can also be viewed as being known.
Such a pivoting/tilting camera system is known from DE 102 48 023 A1.
DE 102 08 413 B4 describes a tripod head that can be pivoted, for a camera. The tripod head can be pivoted about at least one axis using a motor drive and has a receptacle for the camera. The tripod head is composed of elements of a construction set, namely motor drive modules with a motor housing, as well as a power take-off shaft, and the motor housing has fastening devices for connection of the motor housing with a further element. In this regard, straight rods that resist bending and have clamping elements are used.
Also known is a camera holder for vehicles, having vibration damping, wherein one or more gas pressure or oil pressure shock absorbers having springs or spring elements for vibration damping are disposed in a hinge-shaped holder, relative to a hinge rotation point (DE 20 2013 007 276 U1).
From U.S. Pat. No. 7,209,176 B2, a camera holder used in Hollywood studios is known, which is fastened to a camera with multiple articulation, by way of an upper receptacle.
DE 10 2006 014 441 B4 describes an adjustment apparatus, which can be used for remote-controlled or direct adjustment of assemblies such as light sources or cameras.
It has two pivot axles and two motor units having micro-stepper motors and is constructed without a gear mechanism.
EP 2 416 202 A1 describes a camera stabilization system having a rotation axis of 360°.
From EP 1 887 274 A1, a camera head is known, which has a support arm having a vertical rotation apparatus. A U-shaped receptacle that is open toward the bottom is affixed to the rotation apparatus. The receptacle has a pivoting apparatus on its lateral arms, which apparatus is also structured in U shape and possesses a movable camera holder on its horizontal connection crosspiece.
EP 2 759 480 A1 describes a double-axis and a triple-axis ball head for use in a small unmanned flight device, in particular a drone. Both embodiments have a machine frame arrangement with different frames, which are guided within one another or engage into one another. In the inner frame, a camera receptacle is disposed, which permits a vertical inclination adjustment of the mini-camera (GoPro) by way of a U-shaped receptacle (bracket). Horizontal adjustability of the mini-camera is not possible with this arrangement. A further mounting is disposed centrally on the U-shaped receptacle, as a cantilever arm, which mounting can perform a rotational movement. At the other end of the cantilever arm, there is a fourth mounting, which again is structured in U shape and permits a further rotational movement. The apparatus is fastened to the flight device by means of this mounting. In total, the entire apparatus has three drives.
The apparatus is unsuitable for high-speed recording, because it does not have any blur protection. Only a mini-camera (GoPro) can be used as the camera technology, not a professional high-speed camera. The entire light-weight construction is preferably designed for use in mini-helicopters (drones). A closed double-cage structure is implemented.
In US 2010/0079101 A1, a camera mounting is described, which can be fastened to a car and has a stabilization system. The apparatus is preferably structured as an open tilting/rotation device, in the upper U-shaped mounting of which a camera is guided by way of a receptacle in swallowtail form. It is thereby structured as an open triple frame construction. The swallowtail-shaped camera receptacle is supported on the horizontal shank of the upper U-shaped frame by way of a central tilt joint, and can be tilted laterally to a limited extent. Furthermore, an embodiment is described, which has a triple frame. This embodiment also has no effective blur protection for high-speed recordings. This camera mounting is merely a simple holding apparatus for amateur video recordings without a professional background.
EP 0 966 154 A1 describes a method and an equipment for recordings that can be moved in three axes. In this sense, this arrangement is a triple-axis remote control system for a camera, having a joy stick as a control element and having a data line to the camera. A camera guide that can be moved in three axes is disposed below the camera—between it and the camera tripod—wherein each movement direction is achieved by way of a toothed belt/V-belt drive. This apparatus, which is also not protected against blurring, is completely unsuitable for professional high-speed recordings.
DE 42 30 838 A1 describes a tripod in a modular system, having one or more suction or adhesion feet for cameras or the like, wherein the two or more suction feet are connected in bridge-like manner by means of tubular profiles or rod profiles, and the profiles are clamped in the attachment eye, in insertable manner, and form a tubular bridge.
All the known camera mountings have the following disadvantages:
An object of the invention is to provide a mounting for preferably movable camera recordings, which can be fastened to moving objects in three dimensions, in secure and simple manner, and which allows very good recording quality even at high speeds as well as in the off-road sector.
These and other objects are achieved, according to the invention, in that the mounting is made up of multiple arms, wherein each arm is mounted with double articulation, and all the arms are connected with one another by way of a tilt axle and a two-part holder, wherein a vacuum suction cup is attached at each end of an arm, in each instance, of which at least one vacuum suction cup is mounted so that it can be tilted or rotated, and all the vacuum suction cups are connected with a control device and a vacuum pump by way of at least one line, in each instance.
It has proven to be particularly effective to preferably connect three arms with one another by way of the two-part holder and its tilt axle.
The mounting can be connected with a further mounting by way of a connection piece, so that six arms, each having a suction cup, would result.
The arms are structured so that after the arms are aligned on the vehicle, they can be locked in place in a movement direction by way of a lever affixed to the tilt axle.
A further lever for locking this vacuum suction cup in place in a further movement direction is fastened onto the tilt axle of the at least one (third) arm.
The rotation axles of the other arms are structured so that they can be locked in place in a further movement direction.
The control device has a monitoring possibility for the suction forces applied to each individual vacuum suction cup.
The suction forces can be set variably or in fixed manner in different modes.
The control device has a display for constant follow-up of the current suction forces.
The control device furthermore has a function for automatic generation of a selectable suction force for all the vacuum suction cups.
The control device alternatively also has a function for manual generation of a selectable suction force for all the vacuum suction cups.
The control device furthermore has a function for reset of the suction force that is required to release the mounting from the vehicle.
The control device is connected with a rechargeable battery or with the power supply of a vehicle or with both.
Each arm has threaded bores for affixation of screw connection parts for the camera.
Other objects and features of the invention will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood, however, that the drawings are designed as an illustration only and not as a definition of the limits of the invention.
