Title: L-bracket

Description:
The present invention relates to a mounting assembly for mounting a device to a support. This is typically in the form of an L-bracket and is typically expected to be used with cameras, such as photographic cameras. 
     Photographers and cinematographers commonly mount cameras and other photographic and cinematic devices on supports such as tripods and monopods. While such supports are typically provided with a swivel or joint element to allow the device to be configured between different orientations, such as landscape or portrait, moving between the orientations can be cumbersome and can often shift the centre of gravity of the device resulting in a loss of stability. 
     L-brackets, which allow an easy and controlled configuration of a photographic device between different orientations on the support, have become increasingly popular with consumers. They also retain the camera sensor position, which in turn retains the focal plane, which is the signature attribute of an L-Bracket. An L-bracket is a mounting assembly which consists of a base potion and an arm portion positioned at a right angle to the base portion to provide the “L” shape that gives the bracket its name. Each of the base portion and the arm portion typically has a means for connecting to a support, which typically includes a quick-release engagement means which is able to co-operate with a complementary engagement element on the support for easy attachment and detachment. The camera, or other photographic device, is securely mounted on the base portion of the L-bracket such that the arm portion extends parallel to a side of the device. Usually, a face of the arm portion also abuts the side of the device. The L-bracket can then be mounted on the support via either one of the base or arm portions. Using the quick-release engagement of the L-bracket, a user can easily switch between a first configuration in which the device is secured on the support at a first (e.g. landscape) orientation, and a second configuration in which the device is secured on the support at a second (e.g. portrait) orientation. 
     Photographers often want quick access to their camera and carry multiple cameras with them when taking photographs. The desired speed of access is not typically achievable by storing a camera in a bag. This extends to the use of multiple cameras, where space in a bag, or the size of a bag, may become prohibitive to free movement of a photographer to allow them to position themselves as they wish to take a photograph. 
     To address these desires a range of products have been developed to achieve suitable access to cameras and to allow multiple cameras to be carried without over-encumbering a photographer. Such products include the Peak Design Capture Clip and the Spider Camera Holster. These allow one or more cameras to be attached to a belt, bag or strap being worn by a photographer to enable the photographer to be “hands free” when the camera is not in use, without the need to stow away the camera to avoid it getting in the way, while also holding the one or more cameras securely to avoid a camera being damaged or misplaced. 
     There are times when a photographer wants quick access to their camera and to carry multiple cameras while also wanting to allow easy and controlled configuration of a camera between different orientations when mechanically supported, such as by a tripod. However, clip and holster style products are incompatible with L-brackets and other photographic accessories. This is due to the difference in the intended use of the clip and holster style products, namely a hand support, fast reaction photographic style, such as street photography or fashion photography, compared to a more methodical and structured photographic style, such as still life or long exposure photography, for L-brackets. 
     The present invention seeks to address at least some of the above problems. 
     SUMMARY OF THE INVENTION 
     According to a first aspect there is provided an L-bracket for a camera, comprising: a base, an upright arm connected to the base and a fastening element arranged in use to provide a releasable connection between the camera and the L-bracket; and a connector attached to one of the base or the arm, the connector being arranged in use to engage a dock mountable on a strap, the connector having a foot section with a surface shaped to engage the dock, wherein the foot has a cross-section having at least two lines of symmetry to allow the connector to engage the dock in multiple orientations. 
     This provides an L-bracket that is also able to be used to connect to a clip or holster style product. This increases the flexibility the photographer has with their camera due to the ability to carry one or more cameras attached to the L-bracket of the first aspect on a strap worn by the photographer, providing them with quick access to the camera. This is achieved while also allowing a camera to be kept close to hand and safe while a tripod or similar product is being set up. This is not achievable with conventional L-brackets because conventional L-brackets are designed only to fit into a mount on a tripod, such as opposing jaws of an Arca-Swiss style mount, which cannot be linked to a holster style product. The shape of the connector allowing the dock to be engaged in multiple orientations also allows the user to easily engage the bracket with the dock due to the reduced amount of alignment the user needs to achieve to allow docking. This makes the product simple to use. 
     The surface of the foot section may be only a single surface or may be at least one surface, such as a plurality of surfaces, including two surfaces, three, four, five, six or more surfaces. Typically the surface of the foot section may be defined by at least two sides shaped to engage the dock. This allows for the user to select the orientation of with which the dock is able to be engaged and for that orientation to remain fixed once the L-bracket is engaged with the dock. 
     The phrase “multiple orientations” is intended to mean more orientations than a single position and its mirror image, such as the positions of a conventional L-bracket being connected to a tripod mount by a pair of jaws on the tripod with the upright arm of the L-bracket being located to the left of the jaws when viewed from one position and then released and switched to being connected to the tripod by the jaws with the arm being located to the right of the jaws when viewed from the same position. Generally, this is considered as a single orientation. However, should this be considered to be two orientations, the phrase “multiple orientations” could mean more than two orientations, such as three of more orientations. For example, in this interpretation, typically, the connector is shaped to engage the dock in three or more orientations. 
     The L-bracket may be a type of mounting assembly. 
     The connector may be movable relative to whichever of the base or arm the connector is attached to. However typically, the orientation of the connector is fixed relative to the base when attached to the base or to the arm when connected to the arm. This allows for the L-bracket to be engaged with the dock by a repeatable movement. The user is therefore able to become familiar with the movement used to engage the bracket with the dock. This repeatable movement makes the bracket easier to use by the user and avoids the need for the user to have to re-configure the bracket to a configuration with which they are familiar for use with a dock. 
     The location of the connector may be able to be changed. Typically however, the connector has a fixed location relative to the base when attached to the base or to the arm when attached to the arm. As with a fixed orientation, this makes it easier for a user to attachment the bracket to the dock. This is due to the consistent location of the connector allowing the user to become familiar with location of connector for docking instead of needing to check the connector location each time they wish to attach the bracket to the dock. Such a fixed location and/or orientation can allow a user to engage and disengage the bracket with the dock without looking at the bracket or dock once they become familiar with the bracket, which would not be as easily achievable, or achievable at all, if the connector location and/or orientation were not consistent due to an ability to move the connector. This is even the case should a fixed location and/or orientation potentially being initially viewed as an undesirable feature by a user due to the limit this places on the flexibility of the bracket when being used with a tripod, which is its original, and therefore primary, purpose for a photographer. This is because the ability of move the bracket relative to the tripod, which is often desirable when using an L-bracket would be limited when the tripod is engaged with the connector. 
     The fastening element may be positioned in a fixed location relative to the connector location, though typically, the fastening element is movable relative to the location of connector. This allows for different camera shapes and sizes to be used with the bracket while allowing whatever camera is used to be held in the desired position when mounted to a tripod using the bracket. 
     The fastening element may be engagable with the base and with a camera to provide the connection between the connection between the camera and the L-bracket in use. This is as an alternative or in addition to the fastening element being engagable with the arm and with a camera to provide a similar connection in use. Such a connection provides a releasable join between a camera and the bracket. 
     The arm may be a plate having a C-shape provided by an aperture in the plate, the arm thereby having an opening in a side. This allows a cable with a right-angle connector to be connected to a camera mounted on the L-bracket while the camera is mounted to the bracket. 
     Additionally, the arm may have a plurality of attachment elements arranged, in use, to attach the arm to the base plate, the position of the opening in the arm causing the opening to have a different position relative to the base plate when the arm is connected to the base plate by each respective attachment element. 
     By having an opening and a plurality of attachment elements arranged to attach the arm to the base plate, it is possible to provide a mounting assembly having an opening in the arm portion in which the position of the opening with respect to the base plate can be easily varied. The opening in the arm portion provides, in use, access to the device even when the device is fully mounted on the mounting assembly. By changing the position at which the arm is connected to the base plate, the user can easily configure the mounting assembly to suit the dimensions of the device to which it is applied. The first aspect thereby provides a versatile mounting assembly which can be adjusted for use with many different devices, while providing the functionality of a stable and reliable mounting to a support. 
     The base and arm may be orientated at a right angle relative to each other. Such a configuration allows the mounting assembly to function as an L-bracket, while providing the versatility of being adjustable for the device to which the mounting assembly is applied. 
     Whilst the arm may have attachment elements arranged in any position, typically the arm may have opposing ends, the opening being between the opposing ends, and each end may have at least one attachment element. 
     The distance between attachment elements at the ends of the arm and the relative location of the opening in relation to the ends allows a greater variation in the location at which the arm can be attached to the base. By allowing a greater variation in the connection between the arm and the base, it is possible to provide a wide range of positions to which the opening in the arm can be configured. The positioning of attachment elements at the ends of the arm also allows the attachment elements not to interfere with the main body of the arm, such that the aperture can be made as large as possible to provide increased access to the device in use. 
     Typically, the arm may have a front face and a rear face (in addition to the arm having sides for example). Additionally each face may have at least one attachment element. By each face of the arm having an attachment element, the versatility is improved by providing a greater number of positions in which the opening of the arm is able to be placed. Further the attachment elements may be in corresponding positions on each face. This makes it possible to ensure that the load experienced due to attachment with the base is consistent. Furthermore, if the attachment elements at similar or corresponding positions on each face, as is an option, significantly simplifies manufacture of the arm. 
     The L-bracket may further comprise a first securing element, the first securing element providing a connection between the arm and the base. 
     Each attachment element may comprise one or more bores. Furthermore, each of the bores may be arranged, in use, to engage a first securing element engagable with the base. Mounting equipment such as the L-bracket of the first aspect is often used to mount delicate and often very expensive, devices to a support. It is important therefore that any connection between parts is rigid and stable. By having bores arranged to accept and engage a securing element, it is possible to ensure a tight connection between the arm and the base. 
     The first securing element may be movable to allow the distance between the arm and the base to be adjusted in use. For example, the first securing element may be slidable relative to the base. 
     The first securing element may comprise a rail. At least a portion of the rail may have a threaded surface. To co-operate with the threaded surface of the rail, the bores may be threaded bores or have a threaded portion. A threaded connection, such as that provided by a screw, ensures tight and durable attachment of the first securing element to the attachment means. 
     Each of the bores may be through-bores. When the first securing element is longer than the bore, this allows the length of a projecting part of the first securing element to be adjusted and further allows the first securing element to be accessed and adjusted from either side of the connection. Of course, it would be possible for each bore to be a blind-bore or for there to be a combination of through-bores and blind-bores. 
     Each of the through-bores may be distinct and spaced apart from each other. However, to provide additional functionality, typically the through-bores of each attachment means may be joined by one or more slots extending between the through-bores. For example, the slots may be used to clip or attach additional components to the mounting assembly. In some examples, the slots may themselves be through-slots, extending between the front and rear faces of the arm. In such a case, the through-slots can provide a further functionality as a loop for a camera strap, for example. Another advantage of slots between the bores is that this reduces the weight of the mounting assembly. 
     The connector on the base may comprise any element suitable to accept and removably engage a device. Typically, the connector may comprise a connector bore, and the connector bore may be arranged, in use, to engage a second securing element. A connector bore can provide a secure and stable connection between the device and the base, allowing for co-operation with a second securing element. The use of a connector bore as a connector is also advantageous in that it allows a device with an in-built connector, for example, a clip or a push-fit element to be connected to the base. As with the bores of the attachment means, the connector bore may be a through-bore, and may be at least partially threaded. The second securing element may be a rail or a bolt, and at least a portion of the second securing element may be threaded. To provide further flexibility, the attachment means of the arm may also be arranged to engage, in use, with the second securing element. 
     The base may comprise one or more bores arranged, in use, to engage with a first securing element to secure the base to the attachment means of the arm. By having bores arranged to engage with the first securing element, it is possible to reliably secure the arm to the base through the first securing element. In addition to, as an alternative to, the bores, the base may further comprise grooves or recesses arranged to receive and/or guide the first securing element. The grooves or recesses may be separate from, or continuous with, the bores of the base. 
     The first securing element may be slidable relative to the base. A sliding arrangement allows the connection between the arm and the base to be easily and precisely adjusted. For example, such an arrangement allows a user to easily adjust the mounting assembly to suit the dimensions of different devices. 
     The first securing element may be held in position in the bores of the base by a locking member. 
     In order to ensure a sturdy connection between the base and the arm, the first securing element typically is held in position in the bores of the base. The base may further comprise a locking member to lock the first securing element in position. The base may comprise one or more locking members, each arranged to lock one or more first securing elements in position. In the case that the first securing element is slidable relative to the base, once the user has adjusted and selected a configuration of the first securing element, the user may lock the base and arm in position by using the one or locking members. 
     It is important that the locking member is able to engage and maintain a secure hold of the first securing elements. Typically, the locking member may comprise one or more locking screws each arranged to engage one or more first securing elements. Alternatively, the locking member may comprise a clamp or a jaw arranged to grip the one or more first securing elements. 
     An important feature of the mounting assembly is the ability to mount the device to the support at two or more different orientations. To achieve this, the mounting assembly may be mounted to the support at either the base or the arm. The arm may comprise an engagement means for engagement with the support to achieve this. 
     The engagement means (either on the arm or on the base) may be arranged to co-operate with a corresponding member on the support. For example, the engagement means may comprise one or more grooves arranged to cooperate with a jaw on the support. The engagement on one or both of the arm and the base may comprise a pair of grooves on opposing sides of the arm and base respectively. In a case where the mounting assembly is secured and gripped by a clamp or a jaw on the support, having a pair of grooves on opposing sides allows a strong and even application of force from the clamp or jaw. The grooves may be separate and attached to one or both of the base and the arm. Alternatively, the grooves may be integrally formed with one or both of the base and the arm. 
     The grooves of the engagement means may be dovetail grooves, meaning that at least a portion of the groove&#39;s cross section has a trapezoidal or triangular shape, and the groove is arranged to cooperate with a rail or jaw having a complementary shape to form a “dovetail joint”. Dovetail joints provide a secure engagement, and have a high resistance to being pulled apart. This ensures improved stability. Furthermore, such an arrangement allows the engagement means of the base or arm to be easily slid in to a complementary member on the support, improving ergonomics. A further advantage of the use of dovetail grooves is that many support products use dovetail jaws to provide what is known as a “Quick-Release (QR)” mechanism to facilitate rapid attachment and detachment of devices to the support. By using dovetail grooves, the mounting assembly provides compatibility with many supports, further improving versatility of the mounting assembly. For example, the engagement means may take the form of an Arca-Swiss style connection that is arrange in use to connect with a clamp or support with an Arca-Swiss style jaw arrangement. 
     The base may typically comprise an upper surface and a lower surface, the upper surface being arranged to receive, in use, the device to be mounted on the mounting assembly. 
     Many photographic devices have parts which have the ability to extend out of its main volume. For example, some modern cameras are provided with a “flip” screen. Such a screen typically has the capability of being flipped and pulled to extend out of the camera. To accommodate for, and provide access to, parts of the device extending outward, at least one edge of the upper surface of the base may comprise a downward chamfer. 
     As it will be appreciated, many of the parts of the L-bracket described above may be modular and removable. As such, according to a second aspect, there is provided a kit of parts for an L-bracket to the first aspect, the kit comprising: a base; an upright arm connectable to the base; a fastening element arranged in use to provide a releasable connection between a camera and the L-bracket; and a connector attached to one of the base or the arm, the connector being arranged in use to engage a dock mountable on a strap, the connector having a foot section with a surface shaped to engage the dock, wherein the foot has a cross-section having at least two lines of symmetry to allow the connector to engage the dock in multiple orientations. 
     According to a third aspect, there is provided an L-bracket for a camera, comprising: a base, an upright arm connected to the base and a fastening element arranged in use to provide a releasable connection between the camera and the L-bracket; and a connector attached to one of the base or the arm, the connector being arranged in use to engage a dock mountable on a strap, the connector being shaped to engage the dock in multiple orientations. The L-bracket of the third aspect may of course use any combination of features set out above as relating to the first aspect and apply these features correspondingly in respect of the third aspect.

     DETAILED DESCRIPTION 
     An example mounting assembly (in the form of an L-bracket)  1  is generally illustrated in an assembled configuration in  FIG. 1 . The mounting assembly  1  comprises an arm  10  and a base  20  (also referred to herein as a “base plate” due to the base being provided by a plate in the examples described). 
     The mounting assembly  1  arranged to receive a device, such as a camera or other photographic or cinematic equipment, at either one of the arm  10  or the base plate  20 . 
     The arm  10  comprises a plate  11  having an aperture  12  therethrough. The aperture  12  is provided on the arm  10  so as to form an opening  13  in a side, such that the arm  10  is substantially C-shaped. By C-shaped, we mean a shape having the shape of a capital letter “C”. For example, such a shape takes the form of a quadrilateral having a break, or a gap, at one of its sides, as is shown in the configuration illustrated in  FIG. 1 . In other examples, a “C-shape” may alternatively take the form of any other polygon or ellipse having a break or a gap on one of its sides. 
     In this example, the C-shaped arm  10  generally has two pairs of opposing sides: two opposing longitudinal sides, and two opposing lateral sides, the longitudinal sides being longer than the lateral sides. This forms a generally rectangular shape. The opening  13  is provided on one of the longitudinal sides, at a position closer to one of the two lateral sides than the other lateral side. In other examples, the opening  13  can be provided at a position which is equidistant from the pair of lateral sides. The opening  13  may also be provided at one of the lateral sides, rather than at a longitudinal side. In other examples, the lateral and longitudinal sides may have the same length thereby forming a generally square shape. 
     In addition to the two pairs of opposing sides, the arm  10  has two faces. These are separated by the sides of the arm, which provide the arm with its thickness. 
       FIGS. 2A through 2D  illustrate how the arm  10  can be configured to “move” the position of the opening  13 .  FIG. 2A  shows the arm  10  having the opening in a first position (in this example in an upper right quadrant of the arm). The arm  10  of  FIG. 2A  can be rotated through 180 degrees in the plane of the arm  10 , as illustrated in  FIG. 2B , to reposition the opening  13  apparently on an opposite longitudinal side to the arm  10  of  FIG. 2A  (so in this example in a lower left quadrant of the arm). Furthermore, the arm  10  of  FIG. 2B  can be rotated 180 about its longitudinal axis, to further reposition opening  13 . Such a position is shown in  FIG. 2C . This results in the opening being located in a lower right quadrant of the arm in this example. The rotated arm of  FIG. 2C  can then be rotated 180 degrees again in the plane of the arm to provide still another position for the opening  13 . This is shown in  FIG. 2D , which shows an example with the opening in an upper left quadrant of the arm. Due to the asymmetry of the arm  10 , each one of the configurations shown in  FIGS. 2A through 2D  provides the opening  13  apparently at a different location when viewed straight on to one of the faces of the arm. 
     The arm  10  further comprises a plurality of attachment elements  14 . In this example, two attachment elements  14  are provided on the arm  10 , with each of the attachment elements  14  positioned at an opposing end of the arm  10 . Whilst the example shows the attachment elements  14  near the lateral sides of the arm  10 , in other examples the attachment elements  14  can be positioned near the longitudinal sides of the arm  10 . 
     Each attachment element  14  is arranged, in use, to attach the arm  10  to the base plate  20 . In this example, each attachment element  14  comprises two bores  15 . The bores  15  are arranged to receive and engage a securing element  19  for securing the arm  10  directly or indirectly to the base plate  20 . Examples of securing elements  19  include screws, rails, pins, or any combination of these. The bores  15  in the example shown are through-bores, and comprise a threaded surface. The threaded surface of each bore  15  is arranged, in use, to cooperate and engage with a complementary threaded surface on a securing element  19 . Of course, depending on the choice of the securing element  19 , other examples of the arm  10  may comprise blind bores or non-threaded bores. As well as having the threaded surface, the bores have a counter-sunk portion. As is set out in more detail below, this is configured to cooperate with a securing element. Each of the attachment elements  14  are symmetrically positioned on the arm  10 . 
     The pair of bores  15  within each attachment element  14  are joined by a slot  17 . Each slot  17  extends between the two bores  15  in each attachment element  14  to provide a continuous through-bore linking the two bores  15 . The slots  17  can be used to provide additional functionalities, such as a hooking point for a strap or other accessories. 
     It will be noted that, as in the example shown, through-bores can act as attachment elements  14  on both faces of the arm  10 . The bores  15  may be threaded from both a front and a rear face, to provide attachment elements  14  at corresponding positions on both faces. A securing element  19  may engage each of the through-bores  15  from either face of the arm  10 . 
     The arm  10  further comprises an engagement means  16 , arranged in use to cooperate and engage with a corresponding member of a support. By “support” we intend to mean tripod, monopod, ball head joint or any other means for attaching a bracket or mounting plate to a tripod or monopod. The engagement means  16  comprises a pair of grooves on the opposing longitudinal sides. In this example, the grooves are dovetail grooves. By dovetail, we intend to mean that at least a portion of the cross-section has a triangular shape. The grooves can be used to co-operate with a rail or jaw having a complementary shape, to form a “dovetail joint”. In particular, the arm can be secured on a support by clamping the groove in a jaw member on the support. The support may comprise a “Quick-Release (QR)” mechanism to facilitate rapid attachment and detachment of the engagement means to the support. The grooves in this example are intended to be compatible with an Arca-Swiss quick release system. 
     An important feature of the arm  10  is that the grooves of the engagement means  19  are symmetric about the longitudinal centre of the groove. In other words, the “double-sided dovetail” grooves can cooperate with a jaw of a corresponding member on a support when the arm  10  has been rotated about its longitudinal axis. This allows the arm  10  to be attached to the base plate  20  in any one of the configurations shown in  FIGS. 2A to 2D  with either face being closer to the support than the other face. 
     Turning now to the base plate  20 , an upper surface and a lower surface are provided on the base plate  20 . In the example shown, the base plate  20  is arranged to receive a device on the upper surface. 
     The base plate  20  comprises a connector  21  for removably connecting, in use, a device to the base plate  20 . The connector  21  comprises a connector bore  22  and a securing element  23 . The securing element  23  comprises a threaded bolt and is arranged to co-operate, through the connector bore  22 , with a threaded surface on a device, to secure the base plate  20  and the device together. For reference, there are two standard thread sizes that are used for photographic equipment: a ⅜ inch (9.525 mm) thread, and a ¼ inch (6.350 mm) thread. The threaded bolt shown in  FIG. 1  comprises a ¼ inch (6.350 mm) thread, to ensure universal connection with photographic equipment. In this example, the connector bores  22  are threaded at the same diameter as the bores  15  of the arm  10 . This allows, for example, a device to be mounted at either one of the connector  21  of the base plate  20  or the attachment means  14  of the arm  10 . 
     As shown in the figures, the base plate  20  may be provided with a plurality of connector bores  22 . This provides the user with greater flexibility as to the position at which a device may be mounted to the base plate  20 . For example, the connector bore  22  to be used may be chosen depending on the dimensions of the device being secured to the base plate  20 . 
     As described above, the upper surface of base plate  20  is arranged to receive and secure a device to the base plate  20 . In order to ensure a safe and durable interface between the device and the base plate  20 , the upper surface of the base plate  20  is provided with gripping pads  28 . In the example shown, a plurality of gripping pads  28  are provided and are distributed across a significant area of the upper surface. In other examples, a single pad  28  may be provided on the upper surface. The gripping pads reduce the likelihood of device slip, and also act as a cushion to provide a soft interface between the device and the base plate  20 . 
     The base plate  20  further comprises an engagement means  26 , arranged in use to co-operate and engage with a corresponding member of a support. As with the engagement means  16  on the arm, the engagement means  26  of the base plate  20  comprises a pair of dovetail grooves on opposing longitudinal sides. In this case, by dovetail, we intend to mean that at least a portion of the cross-section has a trapezoidal shape. 
     The grooves can be used to co-operate with a rail or jaw having a complementary shape, to form a “dovetail joint”. In particular, the base plate  20  can be secured on a support by clamping the groove in a jaw member on the support. The support may comprise a QR mechanism to facilitate rapid attachment and detachment of the engagement means to the support. Again, this is intended to be compatible with an Arca-Swiss type quick release system. 
     The mounting assembly of  FIG. 1  shows the arm  10  and the base plate  20  being connected via a securing element  19 . A detailed view of the connection is shown in  FIG. 3 . 
     In the example shown, which is viewed from below the assembly in  FIG. 3 , the base plate  20  comprises two bores  24  each arranged to engage with a securing element  19  to secure the base plate  20  to the attachment means  14  of the arm  10 . The base plate  20  further comprises recesses  25  adjacent to the bores  24 . The recesses are arranged to receive and guide the securing element  19 , and to allow a smooth slidable engagement between the base plate  20  and the securing element  19 . 
     In the assembled configuration, the arm  10  is secured to the base plate  20  by a securing element  19 . The securing element  19  engages an attachment means  14  of an arm at one end and a bore  24  of the base plate  20  at the other end. A user can select a desired configuration of the arm  10  (from the configurations shown in  FIGS. 2A to 2D ), and connect the securing element  19  to the attachment means  14  of the arm  10 . The securing element  19  can then be inserted in the bores  24  of the base plate  20  to complete the connection between arm  10  and base plate  20 . 
     In this example the securing element  19  is provided by a rail, a pair of which are used to connect the arm and base plate as set out above. The rails have a cylindrical pole section engagable with the bores  24  of the base plate  20  and a treaded end portion engagable with the arm. The end potion of each rail also has a tapered portion that has a complimentary shape to the counter-sunk portion of the attachment elements  14  of the arm  10 . This allows the end of the rail to be flush with a face of the arm when the arm is mounted to the base plate. 
     The base plate  20  shown in  FIG. 3  further comprises two locking members  27 . Each of the locking members  27  are arranged to lock the position of a securing element  19  in the bore  24  and recess  25  of the base plate  20 . The locking members  27  comprise locking screws whose axis of insertion into the base plate  20  intersects the axis of motion of the securing element  19  in the bore  24 . The locking screws can be tightened to exert a force on the securing element  19  so as to engage and hold the securing element  19  in position. In this way, once a desired orientation of the arm  10  and base plate  20  has been achieved, a user can lock the parts together and ensure that the mounting assembly  1  holds its configuration. 
     As can be seen in  FIG. 3 , the lower surface of the base plate  20  can comprise raised portions or areas of raised surface. The raised surface can be arranged to interact with a complementary portion of an external component. 
     Once assembled, the mounting assembly  1  can be used to mount a device to a support, by connecting a device to the connector  21  (or one of the attachment means  14 ) and then engaging the mounting assembly  1  to a support via one of the engagement means  16  or  26 . 
     Due to the aperture  12  in the arm, the mounting assembly  1  provides a user with significant access to the device even when the device is in use on the assembly  1 . Advantageously, the arm  10  can be configured, using one of the orientations shown in  FIGS. 2A to 2D , to position the opening  13  to provide still further access to the device when in use. The ability to move the position of the opening  13  provides significant versatility to the mounting assembly  1 , which can be adjusted and configured for use with a large number of devices. A particular advantage of the opening  13  is that it allows the user to connect to the side of the device cables having right-angled connectors. 
     Some example configurations of the mounting assembly  1  have been illustrated in  FIGS. 4A to 4C .  FIGS. 4A and 4B  illustrate example configurations of the mounting assembly  1  in which the orientation of the arm  10  has been rotated by 180 degrees about its longitudinal axis. A user may effect a transition between the two configurations of  FIGS. 4A and 4B  by disengaging the securing element  19  from the base plate  20  and the arm  10 , rotating the arm 180 degrees through its longitudinal axis and reengaging the securing means to both the base plate  20  and the arm  10 . 
     It can be seen that, by attaching the arm  10  to the base plate  20  at the different attachment elements, the apparent position of the opening  13  with respect to the base plate  20  can be reconfigured. In other words, the distance from the opening  13  to the base plate  20  is different when the arm  10  is connected to the base plate  20  by each respective attachment element  14 . 
       FIG. 4C  shows an alternative arrangement with the arm  10  extending downwardly from the base plate instead or upwardly as in  FIGS. 4A and 4B . This is achieved by the manner in which the securing element  19  and arm are arranged relative to the base plate. This allows the arm to be used as a handle or as an alternative support means when the device mountable to the base plate is wanted in a different position. 
     In order to facilitate the use of device accessories such as a camera flip screen, the upper surface of the base plate  20  has a chamfered edge along a longitudinal side (i.e. the side on which the engagement elements are located). This provides an angled surface to allow a user to insert their figures between the base plate and the device to a sufficient extend to release the flip screen. 
     The mounting assembly  1  can be seen in  FIG. 5  in an unassembled configuration. It can be seen from  FIG. 5  that the mounting assembly  1  can easily be assembled from a kit consisting mainly of the arm  10  and the base plate  20 . It can also be seen that the orientation of the arm  10 , and thus the position of the opening  13 , can easily be configured by removing the securing element  19 , adjusting the arm  10  with respect to the base plate  20 , and re-engaging the securing element  19 . 
     A further example L-bracket  100  is shown in  FIGS. 6 to 10 . This uses a number of the same components as the example L-bracket shown in  FIGS. 1 to 5 . Indeed, the arm  10  is identical to the arm shown in the example illustrated in  FIGS. 1 to 5  and is able to be varied in the same manner as set out above. As such, as is most clearly shown in  FIGS. 7A and 7B , the arm comprises a plate  11  having an aperture  12  therethrough. The aperture is provided on the arm so as to form an opening  13  in a side, such that the arm is substantially C-shaped. 
     In the example shown in  FIGS. 7A and 7B , the arm  10  has two pairs of opposing sides: two opposing longitudinal sides, and two opposing lateral sides, the longitudinal sides being longer than the lateral sides. This forms a generally rectangular shape. The opening  13  is provided on one of the longitudinal sides, at a position closer to one of the two lateral sides than the other lateral side. 
     In addition to the two pairs of opposing sides, the arm  10  has two faces. These are separated by the sides of the arm, which provide the arm with its thickness. 
     The arm  10  further comprises a plurality of attachment elements  14 . There are two attachment elements provided on the arm, with each of the attachment elements positioned at an opposing end of the arm. Whilst the example shows the attachment elements near the lateral sides of the arm, in other examples the attachment elements can be positioned near the longitudinal sides of the arm. 
     Each attachment element  14  is arranged, in use, to attach the arm  10  to the base  200 . In this example, each attachment element comprises two bores. The bores are arranged to receive and engage a securing element  19  for securing the arm  1  directly or indirectly to a base. 
     The pair of bores  15  within each attachment element  14  are joined by a slot  17 . Each slot extends between the two bores in each attachment element to provide a continuous through-bore linking the two bores. The slots can be used to provide additional functionalities, such as a hooking point for a strap or other accessories. 
     It will be noted that, as in the example shown above in relation to  FIGS. 1 to 5 , through-bores can act as attachment elements  14  on both faces of the arm  10 . The bores  15  may be threaded from both a front and a rear face, to provide attachment elements at corresponding positions on both faces. A securing element  19  may engage each of the through-bores from either face of the arm. 
     The arm  10  further comprises an engagement means  16 , arranged in use to cooperate and engage with a corresponding member of a support, such as a clamp on a tripod, ballhead or other such tripod head. The engagement means comprises a pair of grooves on the opposing longitudinal sides. In this example, the grooves are dovetail grooves. An important feature of the arm is that the grooves of the engagement means  19  are symmetric about the longitudinal centre of the groove. 
     In other examples, the arm may be a simple plate able to be attached to the base  200  by any suitable means, such as by a screw, rail or pin, or be formed as a single unitary piece with the base. Additionally or alternatively, the arm may not have apertures and/or bores as set out above and may simply have grooves for connection to a clamp, such as an Arca-Swiss style clamp, or another suitable form of clamp. 
     Returning to  FIG. 6 , this shows the L-bracket  100  of this example also has a base  200 . This has a number of similar features to the base  20  of the example L-bracket  1  of  FIGS. 1 to 5 . The main difference is that the base of this example has a dockable connector  300  instead of the grooves  26  of the example L-bracket shown in  FIGS. 1 to 5 . More detail regarding the dockable connector is provided below. 
     The base  200  of the L-bracket  100  shown in  FIGS. 6 to 8  comprises a plate with an upper surface and a lower surface. In the example shown, the base is arranged to receive a device, such as a camera on the upper surface. 
     The base  200  comprises a fastening element  210  for removably connecting, in use, a device to the base. The fastening element comprises a fastening bore  220  and a securing element  23 . The securing element comprises a threaded bolt and is arranged to co-operate, through the fastening bore, with a threaded surface on a device, to secure the base and the device together. This uses the standard thread sizes used for photographic equipment set out above in relation to  FIGS. 1 to 5  to achieve the same result. 
     As shown in  FIGS. 6, 7A, 7B and 8 , the base  200  is provided with a plurality of fastening bores  220 . These are provided for the same reason as the corresponding bores of the example shown in  FIGS. 1 to 5 . 
     As described above, the upper surface of base  200  is arranged to receive and secure a device to the base. The upper surface of the base is provided with gripping pads  280 . In the example shown, a plurality of gripping pads are provided and are distributed across a significant area of the upper surface. In other examples, a single pad may be provided on the upper surface. The gripping pads are used for the same reasons as set out above in relation to the example shown in  FIGS. 1 to 5 . 
     The example L-bracket of  FIGS. 6, 7A, 7B and 8  shows the arm  10  and the base plate  200  connected via a securing element  19 . These are connected in the same manner as set out above in relation to  FIG. 3 . As such, in the example shown in  FIGS. 6, 7A, 7B and 8 , the base  200  comprises two bores, each arranged to engage with a securing element to secure the base to the attachment means  14  of the arm  10 . This is the same arrangement as used in the example L-bracket  1  of  FIGS. 1 to 5 . 
     The base  200  further comprises recesses adjacent to the bores. The recesses are arranged to receive and guide the securing element, and to allow a smooth slidable engagement between the base and the securing element. 
     When assembled, the arm  10  is secured to the base  200  by a securing element  19 . The securing element  19  engages an attachment means  14  of an arm at one end and a bore of the base at the other end. A user can select a desired configuration of the arm  10  (in the same way as set out above in relation to  FIGS. 2A to 2D ), and connect the securing element to the attachment means of the arm. The securing element can then be inserted in the bores of the base to complete the connection between arm and base. 
     In this example the securing element  19  is provided by a rail, a pair of which are used to connect the arm and base plate as set out above. The rails have a cylindrical pole section engagable with the bores of the base  200  and a treaded end portion engagable with the arm  10 . The end potion of each rail also has a tapered portion that has a complimentary shape to a counter-sunk portion of the attachment elements  14  of the arm to allow the end of the rail to be flush with a face of the arm. 
     The base  200  further comprises two locking members  270 . These are most clearly shown in  FIG. 8 . Each of the locking members are arranged to lock the position of a securing element  19  in the bore and recess of the base. The locking members comprise locking screws whose axis of insertion into the base intersects the axis of motion of the securing element in the bore. The locking screws can be tightened to exert a force on the securing element so as to engage and hold the securing element in position. In this way, once a desired orientation of the arm  10  and base has been achieved, a user can lock the parts together and ensure that the L-bracket  100  holds its configuration. Two example configurations are shown in  FIGS. 7A and 7B . In  FIG. 7A  the arm is abutting the base with the securing element holding the arm and base in this abutting configuration. In  FIG. 7B  the arm is separated from the base with the securing element locked in position by the locking screws, thereby holding the arm in this separated position relative to the base. 
     In order to facilitate the use of device accessories such as a camera flip screen, the upper surface of the base  200  has a chamfered edge corresponding to the chamfered edge of the example L-bracket shown in  FIGS. 1 to 5 . 
     Turning to the dockable connector  300 , as shown in  FIG. 6 , this is attached to the lower surface of the base  200 . In this example the connector provides a foot that projects downwardly away from the lower surface of the base. Although alternatives are possible, in this example the projection of the foot is along an axis normal to the lower surface and extending away from the base. The footprint of the connector is generally square as shown in  FIG. 8 . 
     As shown in  FIG. 6 , connector  300  is made up of three sections along its length (i.e. between where the connector attaches to the base  200  of the L-bracket  100  and end of the connector furthest from the base). At the end of the connector furthest from the base there is a sole section  310 . This is the shortest section of the foot in terms of length and provides a base to the connector. The outer perimeter of the sole section is upright so that it is parallel with the normal to the lower surface of the L-bracket base and with the length of the section. 
     An ankle portion  320  is provided at the attachment of the connector  300  to the L-bracket base  100 . This section has a narrower width than the sole section and a slightly larger length. Additionally, this section has an outer perimeter that is parallel to the normal of the lower surface of the L-bracket base and the length of the section. 
     The final portion of the connector  300 , which joins the sole section  310  to the ankle section  320  is a tapered section  330 . The tapered section provides a chamfer to transition the width of the connector between the width of the sole section and the width of the ankle section. Accordingly, the outer perimeter of the tapered section is inclined relative to the normal axis of the L-bracket base  100  lower surface. 
     The chamfer of the tapered section  330  provides a straight inclined surface without any convex or concave sections. This gives the tapered section a smooth, featureless surface. 
     The height of the tapered section  330  relative to the height of the other sections is approximately the same as the height of the sole section  310  and ankle section  330  combined. The sole section has a height of about a third of the height of the tapered section and the ankle section has a height of about two thirds of height of the tapered section. 
     As shown in  FIG. 9  and  FIG. 10 , the shape of the connector  300  allows the connector to removably dock with a docking clip  400  on a strap  500  worn on the body of a user  600 . This is due to the complementary shapes of the connector and an aperture in the clip. 
     Due to the square footprint of the connector  300 , the L-bracket is able to be docked with the clip  400  in multiple orientations. For example, as can be seen from  FIG. 9 , the clip has a width generally aligned across the body of the user. This width is greater than the height of the clip, which is generally aligned with the height of the user. As shown in  FIG. 9  and  FIG. 10 , with the connector docked with the clip, the length of the base  200  is generally aligned with the width of the clip. It is also possible for the length of the base  200  to be aligned with the height of the clip by removing the connector from the dock, rotating the L-bracket by 90 degrees about an axis perpendicular to the width and length of the clip and re-docking the connector with the clip. Accordingly, the L-bracket may be docked with the clip in up to four orientations, each provided by a 90 degree rotation relative to this axis. 
     In the example shown in  FIGS. 6 to 10 , the connector  300  is able to be docked with a Peak Design Capture Clip. In alternative examples, the connector is able to be docked with an alternative holster style clip. For example, the connector of this example is able to be replaced with a connector in the form of a pillar projecting outwardly and downwardly from the lower surface of the base  200  of the L-bracket  100 . This pillar has a narrow waist section between an end potion and a join to the L-bracket base, the end section being generally spherical in shape with a wider diameter than the diameter of the waist. Such a connector would provide an ability to connect the L-bracket in multiple orientations to a Spider Camera Holster. When this alternative example is used, the L-bracket base may have the dovetail grooves present in the example L-bracket shown in  FIGS. 1 to 5 . These grooves provide an engagement means for engagement with a support, and alternatives to the grooves may also be used. 
     As noted above, the connector  300  shown in  FIGS. 6 to 10  has a generally square footprint, and each of the four sides of the connector  300  is provided with a sole section  310 , an ankle section  320  and a tapered section  330  as described above. That is, each side of the square connector  300  comprises a straight ankle section  320  extending from the attachment of the connector  300  to the L-bracket base  100 , a chamfered edge constituting the tapered section  330 , which in various examples projects outward from the ankle section at an inclined angle to the sides of the ankle section, and a straight sole section  310 . This arrangement results in the connector  300  having a cross-section having two pairs of opposing sides which are complimentary and which can both be used to dock the connector  300  to a clip  400 . Each pair of sides allows the connector to dock in at least two orientations. In other words, the cross-section of the connector  300  has four lines of symmetry. The connector  300  can therefore be docked to the clip  400  in four different orientations. 
     The connector  300  has been described above as having a generally square footprint. Whilst a perfect square has two opposing sides of equal length, if one of the two opposing pairs of sides has a length which is slightly longer than the other pair, the footprint has two lines of symmetry and therefore the connector can be docked in two different orientations. As such, by ‘generally square’, we intend to mean that the connector has a cross section with at least two lines of symmetry, preferably with four lines of symmetry for a perfect square. 
     It will be appreciated that the shape of the cross-sectional footprint of the connector  300  (and the resulting lines of symmetry of the footprint) can determine the ability of the connector  300  to dock to the clip  400  in multiple orientations. In examples other than the one illustrated in  FIGS. 6 to 10 , the connector  300  can be provided with a different shape having a different number of lines of symmetry. For example, a hexagonal footprint provides three pairs of straight/chamfered edges which can each be used to dock the connector in at least two orientations. Such an example would therefore result in a connector  300  which can be docked to a clip  400  in six different orientations. 
     The shape of the connector  300  of the example shown in  FIGS. 6 to 10  allows the connector to also be attached to an Arca-Swiss style connector, such as those common on a clamp of a tripod head. This allows the base  200  to retain the ability to connect to a clamp, such as a clamp of a tripod head while still allowing it to dock with a clip  400 . In order to achieve a suitable ability for a user to use the L-bracket of this example, the connector is attached to the base  200  approximately half way along the length of the base. 
     Additionally, in this example the fastening bores  220  of the base are located within the footprint of the connector, as shown in  FIG. 8 . Since cameras generally have a bore for accepting an attachment to an accessory in the middle of the base of the camera, this relative position of the fastening bores and the connector, and the connector and the base allow suitable positioning of the camera relative to the L-bracket  100 . 
     In other examples the connector  300  may be attached to the arm  10  instead of to the base  200 . Whichever configuration is used, the connector may be formed as a single unitary piece with the base or arm, may be a separable component or may be removable or non-removably fixed (such as by welding) to the base or arm.
