Abstract

A vertical movement stabiliser assembly 2, which forms part of a stabiliser (4, fig 2) for a camera mount, comprises a first pair of arms 6a, 6b which are coâ€�terminus (i.e. equal in length) and which are vertically spaced apart. Proximal ends of the first arms 6a, 6b are pivotally coupled to a handle bracket 8 via pins 10a, 10b and distal ends of the first arms 6a, 6b are pivotally coupled to a first end of a connecting bracket 12 via pins 14a, 14b. A first leg 12a of the connecting bracket 12 extends from the distal ends of the first arms 6a, 6b towards the proximal ends of the first arms 6a, 6b, but is arranged to be shorter than the first arms 6a, 6b. Another end of the connecting bracket is pivotally connected to proximal ends of a second pair of arms 18a, 18b which are coâ€�terminus and vertically spaced. First and second pairs and arms include first and second biasing elements, e.g. helical springs 16, 30, 38 which bias the arms into a rest configuration.

Description

A Stabiliser The present invention relates to a stabiliser for use in stabilising a camera mount. In particular, the stabiliser cancels or smoothes vertical movement or displacement of the camera mount.

Apparatus to stabilise a camera mount are known. In one example, a user wears a vest or jacket which has secured to one side of it an apparatus to stabilise a camera mount The apparatus includes a number of arms which are variously hinged and which traverse from one side of the user's body to the other, wherein the camera mount is located at the distal end of the arm arrangement. This arrangement is both very bulky and relatively heavy for the user to carry. In addition) the vest or jacket to which the arm arrangement is secured is not universal in its size, so different sizes must be provided to allow for different size users.

As an alternative, a 3-axis gimbal camera stabilisation system is known. However, although such an arrangement is able to stabilise a camera mount against rotation in three mutually orthogonal axes) it is unable to stabilise the camera mount against vertical or lateral displacement. Thus, when a camera is carried by a user, the vertical displacement of the camera mount as the user moves is not countered or corrected. Similarly, lateral movement (e.g. in a horizontal plane) of the camera mount by the user is not corrected or countered. In addition) the known 3-axis gimbal apparatus tend to have a handle arrangement which locates the camera mount significantly below the shoulder height/eyeline of the user.

The present invention sets out to address the problems associated with known camera stabilisation systems.

According to a first aspect of the invention, there is provided a stabiliser for stabilising a camera mount, the stabiliser including a vertical movement stabiliser assembly comprising a first pair of vertically spaced parallel arms, the parallel arms being co-terminus and having a proximal end and a distal end; a second pair of vertically spaced parallel arms, the parallel arms being co-terminus and having a proximal end and a distal end; and a connecting bracket pivotally coupled to the distal end of the first pair of arms and pivotally coupled to the proximal end of the second pair of arms, wherein the vertical movement stabiliser assembly has a first configuration in which the first pair of arms, the connecting bracket and the second pair of arms are all substantially aligned with each other; the connecting bracket extends from the distal end of the first pair of arms towards the proximal end of the first pair of arms; a portion of the first pair of arms is located adjacent to a portion of the second pair of arms with the bracket located therebetween; and the distal end of the second pair of arms extends beyond the distal end of the first pair of arms; wherein the vertical movement stabiliser has a second configuration in which the first pair of arms and the second pair of arms are parallel to each other, but out of alignment with each other; and wherein the first pair of arms includes a first biasing element, the second pair of arms includes a second biasing element) and the first and second biasing elements are arranged to bias the vertical movement stabiliser assembly to a rest configuration.

The arrangement of two pairs of parallel) vertically spaced arms connected via a bracket and biased to a rest configuration achieves a damping effect which counters or smoothes vertical movement of the stabiliser. Furthermore, by arranging the first pair of arms, the connecting bracket and the second pair of arms in a Z-type configuration, the stabiliser has a very compact arrangement.

It will be appreciated that the terms "vertical movement" and "vertical motion" refers to an "up and down" motion or displacement in a vertical plane.

In an embodiment of the invention) the rest configuration is the first configuration.

suitably, the biasing elements are helical springs. In this embodiment, as the first and second pairs of arms are urged into an extended configuration by vertical displacement of the stabiliser, the helical springs are extended and a restorative force is exerted by the springs on the arms.

As will be appreciated, camera mounts can be used for relative light cameras as well as relatively heavy cameras. In order to provide an appropriate restorative force for cameras or camera equipment of different weights, at least one of the biasing elements may be adjustable such that it can exert different, pre-determined restorative forces.

In an embodiment of the invention, the stabiliser includes a third pair of vertically spaced parallel arms) the parallel arms being co-terminus and having a proximal end and a distal end, the third pair of arms being arranged in a parallel spaced relationship with the first pair of parallel arms whereby the first pair of arms and the third pair of arms define a gap therebetween; and wherein the bracket is located within the gap when the vertical movement stabiliser assembly is in its rest position.

The inclusion of the third pair of arms in a spaced relationship (typically, horizontally spaced from) with the first pair of arms provides additional strength and stability for the vertical movement stabiliser assembly.

In embodiments which include a third pair of arms, the third pair of arms may include a third biasing element. The third biasing element operates in concert with the first biasing element to provide an additional restorative force The third biasing element may have the same or similar features as the first biasing element. Thus, it may be in the form of a helical spring and it may be adjustable to provide a variable, pre-determined restorative force.

The provision of a third pair of arms allows for the connecting bracket to be substantially U-shaped.

In this form, one of the opposed arms may be pivotally coupled to the distal end of the first pair of arms and the other of the opposed arms may be pivotally coupled to the distal end of the third pair of arms.

In a further embodiment of the invention) the stabiliser includes a fourth pair of vertically spaced parallel arms, the parallel arms being co-terminus and having a proximal end and a distal end, the fourth pair of arms being arranged in a parallel spaced relationship with the second pair of parallel arms; the connecting bracket is substantially U-shaped; and the second and fourth pairs of arms are located within a gap defined by the opposing arms of the connecting bracket when the vertical movement stabiliser assembly is in its rest position.

In such an embodiment, the U-shaped connecting bracket is sandwiched between the first and third pairs of arms located adjacent to the outwardly facing surfaces of the bracket and the second and fourth pairs of arms located adjacent to the inwardly facing surfaces of the bracket.

The vertical movement stabiliser assembly as defined hereinabove counters or damps vertical motion of the stabiliser. However, it is also desired to counter rotation of the stabiliser about any one or more of three mutually orthogonal axes. These axes are often referred to as the X, V and 7 axes or the pitch, roll and yaw axes. Accordingly, the distal end of the second pair of arms (and optionally also the distal end of the fourth pair of arms, where present) may be connected to a 3-axis gimbal assembly which is arranged to counter rotation of the stabiliser in three mutually orthogonal axes.

Suitably, the 3-axis gimbal assembly includes three rotary actuators) wherein each actuator is arranged to rotate about a respective one of the mutually orthogonal axes.

In such an arrangement, the stabiliser may include a sensor which is adapted or configured to sense rotation of the stabiliser about the three axes. The sensor may comprise a single sensor element) two sensor elements or three sensor elements, for example.

In embodiments which include rotary actuators and a sensor element, the stabiliser suitably further includes a controller) wherein the sensor may be connected to an input of the controller, each of the rotary actuators may be connected to an output of the controller and the controller is arranged to energise one or more of the actuators in response to a signal from the sensor. Thus, if the stabiliser rotates about one of the axes, the sensor senses the rotation and sends a signal to the controller. The controller determines the extent and sense of the rotation and transmits an output signal to the relevant rotary controller to counter the rotation by rotating in the opposite sense to the same degree.

In addition to the rotary actuators responding to changes in the orientation of the stabiliser, they may also be controlled to rotate in accordance with a separate input command. Thus) the stabiliser may further include a remote control apparatus, wherein the remote control apparatus is connected to a second input of the controller and the controller transmits a control signal to one or more of the rotary actuators in response to input signals from the remote control apparatus.

It will be appreciated that the controller, the sensor and/or the rotary actuators need to be powered. Accordingly, the stabiliser suitably includes an electrical power source, such as one or more batteries. The electrical power source is typically electrically connected to the controller and the rotary actuators, although in addition, it may optionally be connected to the sensor.

In order that the three rotary actuators are able to rotate about their respective axes, the 3-axis gimbal assembly may include one or more frame elements located between each of the rotary actuators, wherein the frame elements connect the rotary actuators and maintain them in the correct orientation.

At the opposite end of the 3-axis gimbal assembly to the vertical movement stabiliser assembly is suitably located a camera mount receiver in the form of a pair of parallel spaced apart receiver arms. In use, the vertical movement stabiliser assembly and the 3-axis gimbal assembly cooperate to maintain the camera mount receiver in a fixed orientation relative to the horizontal and vertical planes, irrespective of the motion of the stabiliser and the user.

The camera mount receiver is configured to receive standard camera mounts. Accordingly, in an embodiment of the invention, the stabiliser includes a camera mount carried by the camera mount receiver.

As a camera maybe secured to the camera mount in an offset arrangement (i.e. the camera is not located centrally on the camera mount)) the camera mount suitably includes an adjuster which allows the camera to be mounted centrally relative to the camera mount receiver. Thus) the adjuster permits the camera mount to be displaced relative to the camera mount receiver. Such displacement is typically within a plane, for example within a horizontal plane.

As the camera mount receiver is maintained in a substantially fixed orientation, it is useful to be able to orient the receiver in a desired orientation in order that this may be defined by the controller as the fixed orientation. In connection with this, the camera mount receiver may include an orientation indicator, such as a spirit level or bubble level. This allows the camera mount receiver to be oriented in the desired orientation, which is then defined as the fixed orientation by the controller.

The stabiliser is typically held by an operator or user, either directly or via an extension boom) or it may be fixed to a vehicle, such as a land vehicle or aerial vehicle. Therefore, in an embodiment of the invention, the proximal end of the first pair of arms (and also optionally the proximal end of the third pair of arms, where present) is connected directly or indirectly to a handle assembly. The handle assembly may be directly grasped by a user, it may receive an extension boom or it may be used to secure the stabiliser to a vehicle.

In order that the stabiliser may also damp or counter horizontal displacement of the stabiliser, the proximal end of the first pair of arms may be rotatably coupled to the handle assembly, whereby the vertical movement stabiliser assembly is rotatable relative to the handle assembly. In this embodiment) lateral movement of the stabiliser (i.e. displacement of the stabiliser within a substantially horizontal plane) is manifested in a rotation of the vertical movement stabiliser assembly about the handle assembly.

Suitably, the handle assembly includes a substantially vertical component and the vertical movement stabiliser assembly is rotatable about the vertical component, such that the axis of rotation is substantially vertical and the vertical movement stabiliser assembly rotates within a substantially horizontal plane.

As with the vertical movement stabiliser assembly, the rotatable coupling suitably also includes one or more biasing elements arranged to bias the vertical movement stabiliser assembly to a rotational rest position relative to the handle assembly. As the rotation of the vertical movement stabiliser assembly relative to the handle assembly may be in one of two senses (nominally clockwise and anti-clockwise), two opposing bias elements may be provided whereby the biasing forces exerted by each of the biasing elements cancels out at the rest position.

The inertia of the vertical movement stabiliser assembly may vary according to its configuration and the weight of a camera being carried by it. Accordingly, the or each biasing element associated with the rotatable coupling may be adjustable to provide a pre-determined restorative force.

It will be appreciated from the foregoing that as well as direct manipulation by a user, the stabiliser of the present invention may connected to an extension boom or it may be secured to a vehicle.

Thus, the handle assembly may include an accessory mounting plate to which may be secured an extension boom, a vehicle rig and/or other accessories commonly associated with cameras.

Additionally or alternatively, the handle assembly may include a socket or define an aperture which may be used to secure the handle assembly to an extension boom or a vehicle rig.

It will be appreciated that the accessory mounting plate may carry the sensor, controller and/or electrical power source, where present. The accessory mounting plate may also carry a monitor.

In an embodiment of the invention, the distal end of the second pair of arms is connected to a 3-axis gimbal assembly; the 3-axis gimbal assembly includes three rotary actuators, wherein each actuator is arranged to rotate about a respective one of the mutually orthogonal axes; the 3-axis gimbal assembly includes one or more frame elements located between each of the rotary actuators, wherein the frame elements connect the rotary actuators and maintain them in their correct orientation; the proximal end of the first pair of arms is connected directly or indirectly to a handle assembly; and wherein the frame elements and the handle assembly are both hinged such that the stabiliser has an operational configuration and a storage configuration, wherein in the storage configuration, the stabiliser folds substantially flat.

Camera equipment is often bulky and cumbersome to transport. Therefore) the ability to be able to fold flat the stabiliser for storage is useful. In this context, it will be appreciated that the operational configuration refers to a configuration in which the three rotary actuators are arranged to rotate about their respective axes.

According to a second aspect of the invention, there is provided a stabilised camera mount including a camera mount arranged to receive a camera, wherein the camera mount is coupled to a stabiliser as defined anywhere herein.

According to a third aspect of the invention) there is provided a stabilised camera system including a camera secured to a stabilised camera mount according to the second aspect of the invention.

In this aspect of the invention, the camera may be a still camera, such as an SLR camera, or it may be a video camera.

In an embodiment of this aspect of the invention) the camera system may include a monitor carried by the stabilised camera mount.

In a further embodiment of the invention, the stabilised camera mount is hinged such that it has an operational configuration and a storage configuration, wherein in the storage configuration, the stabilised camera mount is in a substantially flat configuration and the camera is secured to the camera mount. Where present, the monitor may also remain secured to the stabilised camera mount.

The ability to configure the stabilised camera mount into a storage configuration with the camera, and optionally a monitor, secured to the mount is useful in reducing the time needed to reconfigure the camera system into an operational configuration.

The skilled person will appreciate that the features described and defined in connection with the aspects of the invention and the embodiments thereof may be combined in any combination, regardless of whether the specific combination is expressly mentioned herein. Thus, all such combinations are considered to have been made available to the skilled person.

An embodiment of the invention will now be described) by way of example only, with reference to the accompanying drawings in which: Figure 1 is perspective view of a vertical movement stabiliser assembly; Figure 2 is a perspective view of a stabiliser according to the invention, including the vertical movement stabiliser assembly of Figure 1; Figures 3a, 3b and 3c are perspective views of the assembly shown in Figure 1 in different configurations; and Figure 4 is a perspective view of the stabiliser in its storage configuration.

For the avoidance of doubt, the skilled person will appreciate that in this specification, the terms "up", "down", "front", "rear", "upper", "lower", "width") etc. refer to the orientation of the components as found in the example when configured for normal use as shown in the Figures.

Figure 1 shows a vertical movement stabiliser assembly 2 which forms part of a stabiliser 4 (shown in Figure 2). The vertical movement stabiliser assembly 2 comprises a first pair of arms Ga, Gb which are co-terminus (i.e. equal in length) and which are vertically spaced apart. The proximal ends of the first arms Ga) Gb are pivotally coupled to a handle bracket 8 via pins ba, lob. The distal ends of the first arms Ga, Gb are pivotally coupled to a first end of a connecting bracket 12 via pins 14a, 14b.

The pins boa and 14b extend away from the first arms Ga) Gb and are connected by a helical spring 16.

The connecting bracket 12 is U-shaped and has opposed legs 12a, 12b.

The first leg 12a of the connecting bracket 12 extends from the distal ends of the first arms 6a, Gb towards the proximal ends of the first arms Ga, Gb, but is arranged to be shorter than the first arms 6a, Gb. To the other end of the connecting bracket is pivotally connected the proximal ends of a second pair of arms 18a, 18b. The second pair of arms 18a, 18b is arranged similarly to the first pair of arms Ga) Gb in the sense that they are co-terminus and vertically spaced.

S

This arrangement of the first arms 6a, 6b and the second arms 18a, 18b results in the arms being maintained in a parallel relationship and extending in the same direction (the direction being defined as from the proximal end to the distal end).

The distal ends of the second arms 18a, 18b are pivotally connected to a gimbal bracket 20 which has extending therefrom a tubular connector 22.

The handle bracketS includes a pair of bearing elements 24a, 24b projecting away from the first arms 6a, 6b. The bearing elements 24a, 24b define bearing apertures therein which rotatably receive therein a handle tube element 26.

Located between the bearing elements 24a, 24b is a torsion spring system 27 including a pair of opposed torsion springs which cancel each other out at a rest position and one of the springs will exert a restorative force when the vertical movement stabiliser assembly 2 is rotationally displaced relative to the handle tube element 26.

The vertical movement stabiliser assembly 2 is arranged such that when the handle tube element 26 is vertical, the legs 12a, 12b of the connecting bracket 12 and the tubular connector 22 of the gimbal bracket 20 are maintained horizontal.

A third pair of arms 28a, 28b is provided opposite to and spaced from the first pair of arms 6a, 6b.

The third pair of arms 28a, 28b mirrors the first pair of arms 6a, Gb. The proximal ends of the third arms 28a, 28b are pivotally connected to the handle bracket 8 and the distal ends of the third arms 28a, 28b are pivotally connected to the leg 12b of the connecting bracket 12. As shown in Figure 1, the pins ba, lob extend through the handle bracket 8 and pivotally secure the proximal ends of both the first arms 6a, 6b and the third arms 28a, 28b to the handle bracket 8.

The third pair of arms 28a, 28b includes a respective helical spring, which is arranged in the same way as the helical spring 16.

In this arrangement, the first pair of arms 6a 6b and the third pair of arms 28a, 28b move in concert and the helical springs 16, 30 bias the first and third arms 6a, Gb, 28a, 28b to a configuration which is substantially perpendicular to the handle tube element 26.

A fourth pair of arms 32a, 32b is provided opposite to and spaced from the second pair of arms 18a, 18b. The fourth pair of arms 32a, 32b mirrors the second pair of arms 18a, 18b. The proximal ends of the fourth arms 32a, 32b are pivotally connected to the connecting bracket 12 and their distal ends are pivotally connected to the gimbal bracket 20.

An upper elongate pin 34 pivotally connect the upper arms 18a, 32a to the connecting bracket 12 and an upper elongate pin 36 pivotally connects the upper arms iSa, 32a to the gimbal bracket 20.

A corresponding arrangement of lower elongate pins (not shown) pivotally connects the bottom arms lSb, 32b to the connecting bracket 12 and the gimbal bracket 20. A further helical spring 38 is connected between the upper elongate pin 34 and the lower elongate pin which connects bottom arms lSb, 32b to the gimbal bracket 20. As with the helical springs 16, 30, the helical spring 38 biases the second and fourth arms iSa, 18b, 32a, 32b to a configuration which is substantially perpendicular to the handle tube element 26.

Figure 2 shows the stabiliser apparatus 4. In the stabiliser apparatus 4, the vertical movement stabiliser assembly 2 is secured at handle bracket end to the handle tube element 26. The handle tube element 26 terminates at its opposite end in a mounting plate 40 which defines a number of apertures to which various components such as a controller) monitor and battery pack can be secured. Extending substantially horizontally from either side of the mounting plate 40 are handle frame elements 42, 44 which have respective user grip members 46, 48 hingedly connected to each end of them.

A 3-axis gimbal assembly is connected to the gimbal bracket 20 via the tubular connector 22.

The 3-axis gimbal assembly includes a first rotary actuator 50 connected to the tubular connector 22. In the arrangement shown in Figure 2, the first rotary actuator compensates for rotation of the handle assembly 42, 44,46,48 about a Z or yaw axis.

A first frame element 52, which is curved through 900 connects the first rotary actuator 50 to a second rotary actuator 54. The second rotary actuator 54 compensates for rotation of the handle assembly 42, 44,46,48 about an X or pitch axis.

A second frame element 56, which is also curved through 90°, connects the second rotary actuator 54 to a third rotary actuator 58. The third rotary actuator 58 compensates for rotation of the handle assembly 42, 44,46,48 about a Y or roll axis.

s connected to the third rotary actuator is a camera mount receiver bracket 60. A pair of camera mount receiver arms 62,64 extend from the camera mount receiver bracket 60. The arms 62,64 curve through 90° and project forwards, with the forward projecting portions of the arms at roughly the same height as the handle frame elements 42, 44.

The camera mount receiver bracket 60 includes a two-dimensional spirit level 66 which allows a user to determine when the forward projecting portions of the arms 62, 64 are horizontal.

The camera mount receiver arms 62, 64 carry thereon a camera mount 68 which is arranged to securely receive thereon a camera. The camera mount 68 is adjustable in a lengthwise direction relative to the arms 62, 64 and also in a lateral direction relative to the arms 62, 64. The lengthwise adjustment is obtained by varying the position on the arms at which the camera mount 68 is secured. The lateral adjustment is obtained via a fixed screw arrangement (not shown).

The skilled person will appreciate that the rotary actuators 50, 54, 58 are powered by an electrical power source (not shown) and controlled by a controller (not shown). The controller receives inputs from three sensors elements (not shown), each of which senses rotation about one of the three orthogonal axes (yaw, pitch and roll or Z, X and 1) and transmits control signals to the respective rotary actuators to counter the sensed rotation. In this way, the camera mount 68 remains in a substantially fixed orientation, regardless of any rotation of the handle assembly.

The vertical movement stabiliser assembly 2 counters vertical motion of the handle assembly 42, 44, 46, 48. This is shown in Figures 3a, 3b and 3c. Figure 3b shows the vertical movement stabiliser assembly 2 in a rest position. Figure 3a shows the vertical movement stabiliser assembly 2 in a configuration following a downwards displacement of the handle tube element 26. In this Figure, it can be seen that the tubular connector 22 of the gimbal bracket 20 remains in substantially the same horizontal plane as shown in Figure 3b. Finally) Figure 3c shows the vertical movement stabiliser assembly 2 in a configuration following an upwards displacement of the handle tube element 26. Again, the tubular connector 22 of the gimbal bracket 20 remains in substantially the same horizontal plane as shown in Figure 3b. 11.

Figure 4 shows the stabiliser apparatus 4 in a storage configuration. As shown in this Figure) the stabiliser apparatus 4 folds substantially flat in this configuration. This is achieved by having the handle frame elements 42,44 hingedly connected to the accessory plate 40

S

In an alternative embodiment, the handle frame elements 42,44 are detachable from the accessory plate 40.

In use, the stabiliser apparatus 4 is arranged in its operative configuration (Figure 2) and a camera is attached to the camera mount 68. The stabiliser 4 is oriented such that the camera is horizontal according to the spirit level 66. This is then defined as the base orientation of the camera and the controller is set accordingly. Once activated, any yaw of the handle assembly about a 7 axis will be corrected by the first rotary actuator 50 such that the camera is maintained in its base orientation.

Any pitch of the handle assembly about an X axis will be corrected by the second rotary actuator 54 and any roll of the handle assembly about a V axis will be corrected by the third rotary actuator 58.

In addition, any vertical displacement of the handle tube element 26, for example as a result of vertical movements by the user, is corrected or damped by the vertical movement stabiliser assembly 2. Similarly, any lateral movement by the user are corrected or damped are manifested by rotation of the vertical movement stabiliser assembly 2 relative to the handle tube element 26.

Such manifestations of the lateral movement are countered or damped by the torsion spring system 27 located between the bearing elements 24a, 24b.

Thus, the stabiliser apparatus is able to counter and/or damp vertical displacement, horizontal displacement and/or rotational displacement about any of the yaw, pitch and roll axes.
