Description

A HOLDER FOR A MOBILE DEVICE

Field of the Invention

The present invention relates to a holder, more particularly a holder for supporting a mobile device on a limb.

Background

It is common for many mobile devices to be carried by a user during their daily activities, for example smartphones, cell-phones, digital cameras and Global Positioning Systems (GPS).

Typically such items are treated with care so as not to become broken or damaged.

In doing so the mobile devices may be provided in a protective case or carried in a bag. Increasingly there is a desire for said devices to be readily accessible without having to be held by a user and many are provided with cradles in which they can be located, for example when travelling in a vehicle. However, such cradles are not generally suitable for being carried by the user, so often such devices are carried in pockets or bags and removed and held by the user when being used.

Additionally some cradles may prevent some actions from being carried out on the device thus limiting their functionality. This may limit the user in some situations if they require their hands for use in other tasks and therefore may not easily carry the device, for example if exercising or pushing a pram. In these situations the user may need to stop the activity in order to access and operate the device, which can be undesirable.

In other situations devices may be provided in a more accessible location being located for example in a pocket or sleeve positioned on the user or user's bag.

However operation of the device may be limited by the pouch and therefore functionality of the device is restricted, meaning that the device may still need to be removed from the case for full use.

Summary of the Invention

According to the present invention there is provided a holder for a mobile device comprising: a frame for holding said device, the frame arranged on a base, the frame is capable of movement about a plurality of axes relative to the base by means of at least one joint and at least two adjustable straps for securing the holder to a user's limb.

In this way a device, such as a smartphone, can be located in the frame and positioned on a wearer's limb enabling the device to be used for taking photographs or other activities such as viewing the device whilst being fixed on the limb.

Other devices to be held in the holder may include cell-phones, cameras or Global Positioning Systems (GPS) such as satellite navigation devices.

Advantageously the holder allows the device to be moved in plurality of axes relative to the base so that the device can be tilted and/or rotated in order to expose a rear face of the device. For example the holder may enable a rear face of a smartphone to be exposed to reveal a rear mounted camera lens in order to allow a photograph or film to be taken without having to remove the device from the holder.

Therefore the device is less likely to be dropped or damaged because the wearer's hands are free and a plurality of orientations can be achieved including landscape or portrait and any orientation in between whilst the device is mounted securely on the holder.

In preferred embodiments said strap(s) enables the holder to be worn about the wearer's arm, or more particularly forearm or wrist, wherein the device is thereby presentable to the wearer in a plurality of orientations as defined by the axial movements about the joint.

In preferred embodiments the frame is dimensioned to receive the device. In this way the device is securely held by the frame on the holder. The frame is typically dimensioned to match the device. Typically the frame is substantially rectangular for receiving a smartphone, although othel shapes may be provided for different devices.

Preferably the frame is dimensioned to accommodate the device so that the device is fully or partially enclosed by the frame. For example if partially enclosed the frame may be dimensioned to house for example the smartphone wherein the touchscreen, buttons or connection points are uncovered so as to enable the smartphone to be readily used whilst held in the frame.

In other embodiments the device may be fully enclosed for example wherein portions of the frame are transparent or flexible so as to enable the device to be operated or operable whilst housed within the frame. In this way the frame may additionally be waterproof and dust proof so as to befter protect the device.

In a fully enclosed frame arrangement the frame may be openable or may provide an opening to accept the device and through which the device can be inserted and once in position held in place, for example by catches, clips and/or hooks.

In some embodiments the frame may include a displaceable opening such as a flap of lid which can be displaced by for example a hinge in order to allow the device to be inserted, for example in a similar manner to that of a cassette being placed in a player.

The frame may be formed from a lightweight, strong, durable material such as synthetic plastic. It may be envisaged that the material may be rigid, semi-rigid or flexible or a combination depending upon the device. In this way the frame is specific for particular devices so as to enable optimal usability.

In some embodiments the frame may be interchangeable to the holder so as to allow different frames to be fitted to the holder and thereby different devices to be used with the holder.

Preferably the frame is rotatable upon the base by a first joint that allows the device to spin around 360 degrees upon the frame. In this way the device orientation can be altered by spinning the frame that is holding the device relative to the base which remains fixed.

Ideally the first rotation point is centrally located on the frame and base.

In some embodiments the rotation may be incremental so as to enable the frame to be fixed at particular positions, for example at 45 degrees, 90 degrees and 180 degrees. In preferred embodiments each joint has 12 predetermined rotation points so that the device can be arranged and fixed at any one of 12 pre-set positions. In this way the device can be locked in position to prevent unwanted movement during use, for example when taking a photograph.

Typically each position may be distinguished by an audible click or sensation to indicate that one of the pre-set positions has been reached. For example the joint may turn on a resistance hinge or ratchet that clicks when each position is reached.

In some embodiments the positions may be visually marked, for example to include increments on the holder to indicate any at which the device is arranged Alternatively or additionally the rotation of the frame may be user selected so as to be at any angle the user desires.

The joint connecting the frame and the base, forming the rotation point, may comprise a hinge, spring, ball joint or screw-thread to hold both parts together whilst also allowing rotation.

Preferably the rotation point may have resistance to prevent free movement about the rotation point without application for force by a user. Ideally when no turning force is applied by the user the frame remains at that orientation to which it is rotated until further force is applied.

In some embodiments incremental rotation may be controlled by a ball and recess/aperture arrangement wherein the frame and base are arranged parallel to each other so as to be one above the other. One part, either the frame or base has a ball arranged in a track and the opposing part has a plurality of recesses or apertures. The parts are joined by a spring or springs so that the parts can be separated enough to disengage the ball from one recess/aperture and allow movement to another. When the ball and a recess/aperture are aligned the parts are fixed in position at a predetermined orientation.

In some embodiments the base may have raised edges on one or more sides forming a cradle into which the frame sits in use. For example an upper end and a lower end of the base may be raised in order to cup the device. In such an embodiment the frame and base may have corresponding rounded edges to allow the frame to spin freely when cupped by the base.

In other embodiments the frame is arranged upon the base wherein the base has no raised edges to cup the frame.

In preferred embodiments the holder includes a plate intermediate the base and the frame that provides a second joint that also allows articulation of the frame and thereby the device relative to base.

Ideally the second articulation point allows the device to be partially displaced from the base to reveal a rear face of the device.

Advantageously this allows for the actions to be carried out using equipment arranged on a rear face of a device such as exposing a camera lens and therefore allowing photographs to be taken.

Typically the plate is fixed to the frame so as to allow the frame to be tilted from an edge in order to allow the entire rear face of the device to be exposed.

Preferably the plate also enables rotation. Therefore the holder has two rotation points; a first rotation point between the base and the plate, and a second rotation point between the plate and the frame. Typically the first rotation point on the base is centrally mounted and the second rotation point on the plate is at an edge of the frame and therefore mounted off centre.

Advantageously as the first rotation point is typically centrally mounted the second rotation point allows further adjustment to the orientation of the device to provide a greater selection of orientations of the device. For example the dual rotation points ensure a camera lens is fully exposed and allows the wearer to keep the limb/holder out of view from the image captured.

Typically the second joint allows movement in plural axis so as to allow the tilt mechanism to displace the frame from the base and to also allow rotation about the point of tilt. For example the joint may comprise a double hinge or ball and socket arrangement.

In preferred embodiments the frame is displaced from the plate by a sprung mechanism for example including a torsion spring. In this way the frame is forced away from the plate so as to reveal the rear face of the device.

In some embodiments the frame may be displaced from the base by a stay that can be arranged to hold the frame in the displaced arrangement from the base.

Preferably the holder may include a button, lever or dial for releasing the sprung mechanism in order to displace the frame holding the device from the base.

The plate is typically of a lesser size that the device so as allow equipment on the rear face to be exposed, such as a lens. For example the plate may be less than half of the device size.

In an alternative embodiment the plate may include cutaway portions that correspond to equipment on the device which is required to be exposed. Therefore the plate is not required to be smaller than the device and may even be larger than the device.

Preferably the holder includes two straps arranged at either end of the base for securing the holder to a wearer's limb.

In preferred embodiments each strap may be formed from two halves that pass around the limb and connect in order to form a continuous 0-shaped loop.

In preferred embodiments the straps comprise a cuff that can be incrementally adjusted to the size of a wearer's limb.

Preferably the cuff is rigid in the form of a handcuff adjustable by means of a ratchet mechanism. In this way each strap can be incrementally sized to the limb.

Each half of the rigid cuff is ideally semi-circular so that when closed they define a closed loop or circle (0-shaped loop) when the halves are joined together.

Advantageously this allows for the cuff to be easily fitted to the limb as the two halves are shaped to correspond one to another so as to allow the wearer easily to position and fix the straps using one hand.

Typically the two halves of each strap are connected by a ratchet mechanism that allows the two halves to be secured together in the 0-shaped formation so as to remain fixed on the limb until removed by the wearer.

Preferably one end of the cuff is fitted with or includes a toothed portion and this is received by the second cuff which includes a ratchet so as to engage the two halves of the cuff together. In this way the cuff can be incrementally adjusted, quickly and incrementally, in a similar way to that of a conventional handcuff.

Ideally the holder includes a release mechanism to separate the straps so that they can be removed by the wearer.

Preferably the release mechanism comprise a quick release mechanism wherein a button, switch, lever or other disengagement means is actuated so as to loosen and/or separate the straps so that the holder can be removed from the wearer's limb quickly.

In a preferred embodiment the rigid cuff includes a button which is pressed to disengage the two halves of the cuff.

In some other embodiments the strap may be joined by a buckle, clip or hook and loop means such as Velcro (RTM).

In another embodiment the straps are joined and adjusted by a ratchet lacing mechanism wherein a dial can be twisted to tighten or loosen the strap about the arm so that the straps are wrapped snugly around the arm in use. Advantageously the ratchet lacing mechanism may enable the strap to be tightened to the arm shape for example to accommodate the wrist and forearm.

In some embodiments the cuff may be formed from a semi-rigid material so as to allow the strap to flex. This may improve comfort to the wearer.

In some embodiments the straps may be fixed to the limb in a two-step process wherein in the straps are first arranged in a loose 0-shaped formation, the limb is inserted through the loop and the straps are then tightened to the desired diameter to secure the holder comfortably on the wearer. In this embodiment the straps may be permanently fixed in the 0-shaped formation.

Advantageously the straps may be dimensioned or arranged in such a way as to be narrower at one end when arranged about the limb so as to accommodate arm shape, for example typically narrower at the wrist.

Typically the cuff is not fixed tightly to the limb, therefore allowing circulation of air about the holder to prevent excessive sweating under the holder and straps.

Ideally the cuff is fitted close to the wearer's skin so as to limit movement of the holder on the limit but to prevent the cuff indenting the wearer's skin which may lead to discomfort and restricted circulation of blood.

In some embodiments the holder may include and absorbent layer against the wearer's skin so as to limit sweating and to improve comfort. For example the holder and/or straps may include a layer of soft, absorbent fabric.

In other embodiments the straps may be formed from a flexible, lightweight, strong, durable material that is not susceptible to stretching after repeated use. For example the strap may be formed from synthetic plastic such as rubber or silicone.

Preferably each strap is linked to the holder by a hinge that allows at least 180 degree rotation about one hinge so as to allow the holder to be flipped over' in order to change orientation of the device relative to the limb from a first position wherein the device is outward facing (away from the limb) to a second position wherein the device is inward facing (towards the limb).

In this way only one strap may be removed to allow the holder to be flipped over whilst the other strap remains on the limb but is moved up or down the limb to the new position. The fixed strap may require resizing to accommodate the new part of the limb.

Advantageously this allows the device to be inverted to face the limb so that it is protected from damage; for example when not in use.

Ideally the strap is attached to the base by an articulated mounting such as a hinge that allows pivot movements in order to allow the holder to be flipped over.

In some embodiments the strap can articulate about the strap in two or more axes.

Advantageously this can allow the two halves of the cuff to be inverted and arranged in an M' formation, when open and not being worn, in order to provide a stand for the device on a surface. In this way the device can be arranged on a surface for viewing and use.

In some embodiments an outer face of the strap may include a flattened portion for resting on a surface. For example so as to allow the straps to serve as a stand when in the straps are in their closed 0-shaped formation whereby the flattened portion interfaces the surface.

In some embodiments the base may be permanently fixed to or integrated with the frame and/or strap. In other embodiments the frame and/or strap may be detachable so as to enable alternative straps or frames to be used.

In some embodiments a stay may be provided so as to maintain the holder in a particular orientation, so for example the holder can be positioned by the user on a surface.

The holder may include a latch or similar so as to lock the frame in orientations, and particularly when not raised from the strap thereby preventing tilt when not required and further securing the frame.

It may be envisaged that in some embodiments the frame may only be rotated, or only tilted.

In preferred embodiment the holder includes at least one torch. Typically the torch is arranged on at least one side of the holder so as to not interfere with the device in any way.

Advantageously the holder may be provided in different colours, materials and patterns so as to appeal to different users and so as to accommodate and match different devices. For example limited edition holders may be provided for occasions or particular brands.

The base 110 is rectangular having a raised upper end liSA and lower end 115B.

The base 110 defines a space into which the frame 120 is located so as to be situated above the base 110.

The frame 120 is rectangular have rounded ends that correspond to the base 110 so that the frame 120 can rotate within the upper end 1 iSA and lower end 1 15B of the base.

The frame 120 is mounted to the base 110 by means of a joint 150 (Figure 3, Figure 4). The joint is centrally located and allows the frame to rotate 360 degrees relative to the base 110.

The base 110 is linked to two straps 130. One strap is arranged at each end 1 iSA/i 15B.

The straps 130 are linked to the base 110 by a hinge that allows the strap to pivot 180 degrees in relation to the base 110. This allows the holder to be flipped' from a first orientation wherein the device faces away from a limb to a second orientation wherein the devices faces towards the limb and is therefore protected.

The straps 130 have a male end 135A and a female end 135B wherein the female end 135B mates with the male end 135A in order to engage the ends together and form an 0-shaped loop around the limb. The male end 135A is notched so as to be received by a ratchet mechanism on the female end 135B.

In this way the size of the 0-shaped loop can be adjusted to the size of the wearer's limb.

Figures 6 and 7 show the holder having the frame 120 displaced from the base 110 by means of a sprung mechanism.

The frame is mounted upon a plate (not shown) that is attached by a joint 150 that enables the frame to be displaced from the base when released thereby revealing a rear face of the device 500 held in the frame 120.

In this way equipment on the rear face of the device can be exposed, for example a camera lens on a smart phone.
