A hinged door is rotatable about the hinge between a closed position in which the rings are closed and an open position in which the rings are open. The RF transparent first layer and the outer and inner clips are formed of a material such that radio frequency transmissions can be transmitted therethrough.

Description

RF transparent housing with integral clip

technical field

The invention relates to a housing for a mobile device. The housing is made of a radio frequency ("RF") transparent material such that when disposed within the housing, RF transmissions can be sent and received by the mobile device through the housing material. The housing also has a clip integral with the housing so that the housing itself can be attached directly to an item worn by the user, such as a loop, strap, strap, ring or the like.

Background technique

Cases for mobile devices have been designed to provide at least some protection from impact events, such as when the device is dropped, bumped, or otherwise struck. These cases are typically placed in a pocket or bag when carried by a user. This can be a problem in emergency situations as it can make it difficult or even impossible to access the mobile device.

Other housings for mobile devices have incorporated loops on the housing to which clips, shackles or the like (eg carabiners) can be attached. The clip or shackle can then be attached to the item worn by the user. But this can be cumbersome and uncomfortable because the clip or shackle rotates at an angle relative to the housing when attached to the hoop. Additionally, the loop of the housing and the clip or shackle can rub together during use, which creates wear on the loop, potentially leading to loop failure and wear and tear of the device.

Another housing produced by Elecom incorporates hook locks into the sides of the aluminum bumper housing. But the case must be attached to the mobile device with screws, making it difficult to put on and take off the case. In addition, the bumper housing is aluminum, which may provide sufficient strength for the shackle. But aluminum, like other metals, can block or interfere with RF transmissions, which may be why the case is designed as a buffer rather than a complete case. Additionally, aluminum provides little impact absorption.

Detailed ways

It should be understood that the drawings and description of the present invention have been simplified to show elements that are relevant to a clear understanding of the invention, while many other elements that are conventional in the art have been eliminated for the sake of clarity. Those of ordinary skill in the art will recognize that other elements are desirable in order to practice the invention. However, because such elements are well known in the art, and because they would not facilitate a better understanding of the present invention, a discussion of such elements is not provided herein.

The present invention will now be described in detail based on exemplary embodiments. It is noted that any numerical range disclosed herein is included as individually disclosing each subrange and number (whole integers and fractional fractions) within the disclosed range. For example, a disclosed range of 1-100 is intended to individually disclose 20-90, 40-80, 30.5-50.2, 20, 67.3, 84.512924, and every other range and number falling within the recited range.

A housing according to an embodiment of the invention may be achieved by providing the interior of the housing with a shock-absorbing crash-resistant geometry in the form of triangular ridges protruding from the inner surface of the sides of the housing. The narrow tops of the ridges contact the surface of the device. When a force is applied between the outside of the housing and the device, such as during an impact event, the force causes the triangular ridge to deform against the surface of the device. Further deformation of the ridge increases the volume of deformed material as the force increases. This configuration allows the case to absorb impacts and reduces the forces transmitted to the device within the case in the event the device and case are dropped on a hard surface.

1-8 respectively show an upper side view, a rear view, a right side view, a left side view, a lower side view, a front view, a front view, a right front perspective view and a right front development of a housing according to an embodiment of the present invention view. The housing 1 comprises a first layer or shell 2 and a second layer 3 . The first layer or shell 2 comprises a rear side having an inner side surface 4 and an outer side surface 6 opposite the inner side surface. The upper side 7, the lower side 8, the left side 9 and the right side 10 extend from the outer side surface 6 of the rear side towards the front of the housing 1 in order to form the pocket in which the second layer 3 will be - and eventually the mobile device can be placed or recesses. The second layer 3 also includes a corresponding rear side having an inner side surface 21, and one or more of corresponding upper, lower, left and right sides. A pocket or recess 19 for receiving a mobile device may be formed in the second layer 3 .

In one embodiment, the rear sides of the first layer 2 and the second layer 3 overlap each other. The rear sides of the first layer or shell 2 and the second layer 3 are also preferably substantially coextensive with each other such that the rear side of each layer covers at least 50% of the surface area of the rear side of the other layer. It is also preferred that the respective upper, lower, left and right sides of the first layer 2 and the second layer 3 are substantially coextensive with each other such that the respective upper, lower, left and right sides of each layer At least 50% of the surface area of the corresponding side of the other layer is covered. In addition, it is preferred that the rear of the housing (formed by the rear sides of the first layer 2 and the second layer 3) is configured to cover at least 90% of the rear of the mobile device when the mobile device is arranged within the housing (if not all of them).

According to another embodiment, the respective upper, lower, left and right sides of the first layer 2 and the second layer 3 are only partly coextensive with each other such that the respective upper, lower, left and right sides of the first layer 2 The right side covers only a part of the corresponding side of the second layer 3 .

The first layer or housing 2 is preferably formed from an RF transparent rigid or hard non-metallic material to form a rigid/hard housing that provides at least some impact protection as well as protection from being penetrated by impact with a sharp object. Examples of suitable non-metallic RF transparent rigid/rigid materials include hardened plastic materials, rigid or semi-rigid plastic materials, rigid/hard rubber materials, polycarbonate materials, para-aramid materials, wood, glass, Quartz and any combination thereof, and in any color or texture. Preferred materials include thermosets, polycarbonate, poly(methyl methacrylate) ("PMMA"), acrylonitrile butadiene styrene ("ABS") with a hardness of Shore 30D to Shore 100D , PMMA, polyethylene terephthalate ("PET"), high hardness thermoplastic elastomer ("TPE"), and thermoplastic polyurethane ("TPU") with Shore 30D to Shore 100D, and any combination thereof. The hard protective case can be designed to mimic the finished product of existing mobile devices such as phones, MP3/4 players, tablets, laptops, electronic security devices, and other mobile electronic devices. Many users like the feel of the original electronic device and would like to maintain that feel, but still want to protect their device. The hard protective outer shell of the present invention has a low coefficient of friction. This allows the device to slide easily in and out of the pocket with little resistance and without pinching clothing material - a major complaint from users when elastomeric material is used for the outside of the housing.

The outer surface of the first layer or housing 2 may be provided with a scratch resistant UV hard coat which resists scratches and prevents discoloration of the housing due to UV exposure.

The second layer 3, which is preferably formed from a non-metallic RF transparent soft elastomeric material, provides at least some impact protection from impact events such as being dropped or dropped. Examples of suitable materials include thermoplastic elastomers ("TPE"), thermoplastic polyurethanes ("TPU"), polyolefins, silicones, rubbers, and any combination thereof. The second layer 3 can also be designed such that there is no gap between the rear of the mobile device and the inner side surface 21 on the rear side of the housing. This enables the case to have a very strong connection with the mobile electronic device. The second layer 3 may additionally be formed with a flange or rim 20 to secure and hold the mobile device within the housing 1 . The elastomeric layer 3 can also be formed with a portion designed to cover buttons on a mobile device. This allows the user to simply press on the exposed portion of the inner elastomeric layer corresponding to the desired input of the mobile device.

The second layer 3 may also or alternatively be formed from a non-metallic RF transparent non-Newtonian expansion material. The expanded material is soft and pliable at rest, but stiffens and/or hardens upon impact. In this way, the expanded material is able to provide impact protection by distributing the force of an impact event along the surface of the second layer 3 and by absorbing some of the impact force of an impact event. This dual quality of expanded material (i.e., absorbing and dissipating shock or impact forces) allows less material to be used to manufacture the shell—allowing for a thinner, lighter, and less bulky shell, which increases protected Portability of mobile devices - while still providing increased shock and impact protection for the mobile device enclosed therein.

An example of a suitable intumescent material for the second layer 3 includes the available from Rogers Corporation (E.g ST, XT, Shock+ and Aero), XRD ^™ made material and ARTi-LAGE ^™ artificial cartilage foam made from ARTiLAGE ^™ . Impact-absorbing materials with expansion properties, such as foam, are especially preferred.

The expanded material may have a hardness of at least 20 Shore OO, or may have a hardness of at least 5 Shore O. Preferably, the hardness is at least 30 Shore OO, at least 50 Shore OO, at least 60 Shore OO or at least 70 Shore OO. More preferably the hardness is in the range of 20-90 Shore OO, or in the range of 5-61 Shore O. Still more preferably, the hardness is in the range of 30-80 Shore OO, or in the range of 5-40 Shore O. Even more preferably, the hardness is in the range of 40-70 Shore OO.

Preferably, the second layer 3 has a hardness ranging from 60 to 85 Shore A. If the second layer 3 is transparent, it preferably has a hardness of 75-85 Shore A. If the second layer 3 is opaque, it preferably has a hardness of 60-75 Shore A.

Certain additives may cause an otherwise non-metallic RF transparent material to substantially interfere with the transmission of radio frequencies. Examples include carbon, which can be added to color some plastic materials black. In a preferred embodiment, the non-metallic RF transparent material is non-black in order to avoid this problem. Other examples of RF interference additives include metal flakes and other reflective flash flakes, which are also preferably not included or added to the current protective casing.

Each of the rear sides of the first layer 2 and the second layer 3 is 0.5-4.0 mm thick. Preferably, one or more of said layers is 0.6-3.0mm thick. More preferably, one or more of said layers is 0.8-2.0mm thick. Even more preferably, one or more of said layers is 0.9-1.3 mm thick.

The first layer 2 and the second layer 3 may be co-moulded/co-cast together or otherwise permanently fixed to each other, for example with an adhesive.

Alternatively, the first layer 2 and the second layer 3 may be separable from each other as two different pieces. In this case, the two layers may be constructed such that they mechanically join each other to form a unified housing. For example, the first layer 2 may be designed with grooves or cutouts 14 into which corresponding ridges or ribs 15 of the second layer 3 engage (eg by snapping, press fitting or any other suitable mechanical engagement). As another example, opposite sides of the first layer 2 (e.g., the upper side 7 and the lower side 8, the left side 9 and the right side 10, or both) may be designed to snap onto and hold the second layer 3 Second floor3.

For example, one method for making a shell could be:

1. molding the first layer 2;

2. Place the first layer 2 into the overmolding tool and mold the second layer 3 onto the first layer 2 .

Another example of a method for making a shell could be:

1. molding the second layer 3;

2. Place the second layer 3 into the overmolding tool and mold the first layer 2 onto the second layer 3 .

Yet another example of a method for manufacturing a housing may be:

1. Molding the first layer 2;

2. Molding of the second layer 3 (separately from the first layer 2 and before, after or simultaneously with the first layer 2);

3. Bonding the first layer 2 and the second layer 3 together.

It should be noted that additional openings or cutouts 17 may be provided in at least a portion of the housing 1 in order to allow access to various buttons, ports or features of the protected mobile device without removing the mobile device from the housing 1 . For example openings or cutouts 17 may be provided to allow a user to engage a button of the protected mobile device either directly or via the cover 11 of the layer 3 . As another example, a cutout 17 may be provided to form an opening in the housing 1 through which a charging port, audio port, data port or other electrical port of the mobile device may be accessed directly or via a pass-through connection. As yet another example, cutouts 17 may be provided to form openings to expose camera lenses, audio speakers, microphones or other features of the device to be accessed or used without removing the mobile device from the housing 1 .

In one embodiment, at least a portion of each of the first layer 2 and the second layer 3 (corresponding to the rear of the housing 1 ) is translucent, transparent or transparent with a visible light transmission of at least 20% rate (VLT) so that the rear of the mobile device arranged in the housing can be seen by the user through the first layer 2 and the second layer 3 . Preferably, parts of the first layer 2 and the second layer 3 (corresponding to the rear of the mobile device) are translucent or transparent. For example, at least a part, if not all, of the first layer 2 may have a VLT of at least 20%, preferably at least 50%, more preferably at least 80%, still more preferably at least 90% and most preferably 100%. Similarly, at least a part, if not all, of the second layer 3 may have a VLT of at least 20%, preferably at least 50%, more preferably at least 80%, still more preferably at least 90% and most preferably 100%.

The first layer 2 may also comprise relief slots or cutouts 14 in hard material that allow the housing to flex during installation and removal. Corresponding ridges or ribs 15 of the second layer 3 engage into this groove or cutout 14 . The second layer 3 comprises a shock-absorbing crash-resistant geometry in the form of triangular ridges 4, as described above.

The housing 1 comprises a clip 30 integral with the rest of the housing and forming a ring. The clip 30 is formed by an outer clip 31 , an inner clip 32 and a hinged door 33 . The outer clip 31 extends from the first layer or upper side 7 of the housing 2 and is formed from an RF transparent rigid or hard non-metallic material such as those mentioned above. Preferably, the outer clip 31 is formed by the first layer 2 itself. The inner clip 32 is arranged inside the outer clip 31 and is also formed from one of the RF transparent rigid or hard non-metallic materials mentioned above. The inner clip 32 may be formed of the same type of material as the outer clip 31, or may be formed of a different type of material. Preferably, the inner clip 32 is permanently attached to the outer clip 31 .

Preferably, the thickness of the inner clip 32 in the radial direction of the ring formed by the clip 30 is greater than the thickness of the outer clip 31 in the radial direction of the ring. In one such embodiment, the outer clip 32 has a thickness of 1.5mm or less, preferably 0.50mm to 1.50mm, more preferably 1.00mm to 1.30mm, most preferably about 1.20mm. In this embodiment, the inner clip has a thickness of 1.2mm or more, preferably 1.20mm to 10.00mm, more preferably 1.20mm to 5.00mm, most preferably 1.30mm to 3.00mm.

This two-piece design in which the inner clip 32 is thicker than the outer clip 31 avoids certain problems that may arise compared to a one-piece design in which the outer clip 31 is significantly thicker than the rest of the first layer 2 . Specifically, molding a single piece with significantly varying wall thicknesses can lead to various defects in the molded part, such as shrinkage, bubbles, brittleness, and stress concentrations. These defects may weaken the integrity of the housing, cause cosmetic blemishes, cause structural failure, or distort the shape of the housing. By forming the inner clip 32 separately from the outer clip 31 and forming it thicker than the outer clip 31 , it is possible to maintain and even increase the clip 30 compared to a single piece of material of the same thickness combining the outer and inner clips 31 , 32 strength and integrity. In addition, this configuration allows the outer clip 31 to be formed from the first layer 2 with a thickness comparable to the rear sides 4, 6, upper side 7, lower side 8, left side 9 and right side 10, thereby avoiding the above-mentioned problems.

In one embodiment, the inner clip 32 has a protrusion or ridge 36 extending from the perimeter of the inner clip 32 . The outer clip 31 has a corresponding notch or groove 37 into which the protrusion or ridge 36 extends when the inner clip 32 is arranged inside the outer clip 31 . This further secures the inner clip 32 inside the outer clip 31 and strengthens the clip 30 .

The hinged door 33 may be formed from one of the rigid or hard materials mentioned above. Additionally, the hinged door 33 may be formed of metal or alloy. Preferably, no part of the housing 1 is formed of metal or RF blocking material other than the hinged door 33, which may or may not be formed of a metal or alloy. The hinged door 33 is connected to the rest of the housing 1 via a hinge 34 around which the hinged door 33 is hinged. Portion 30 is rotatable between a closed position in which it forms a closed loop with the rest of the housing, and an open position in which the clip does not abut in recess 35 such that clip 30 forms an open loop with the rest of the housing.

In one embodiment, the hinged door 33 includes two legs 33a, 33b that are offset from each other. In this embodiment, the hinge 34 includes two holes or notches 34a, 34b that are similarly offset from each other. The ends of the legs 33a extend into the holes 34a and the ends of the legs 33b extend into the holes 34b. This creates a spring force that biases the hinged door 33 in the closed position.

By forming the first layer 2, the second layer 3, the outer clip 31 and the inner clip 32 from an RF transparent non-metallic material, the housing 1 as a whole can be made RF transparent so that The mobile device in the device sends and receives RF signals.

In a preferred embodiment, the second layer forms the outer clip 31 and the first layer 2, the second layer 3 and the inner clip 32 are injection molded as three separate parts which are then co-molded together as A visually single part that is at the same time transparent and durable. The metal swing door 33 is then attached to the housing 1 . This design not only protects the device and allows it to be worn on many different areas of the user, but also makes the electronic device visible to the user through the transparent housing 1 .

While the embodiments of the housing 1 shown in the figures have separate layers 2, 3 forming the interior and exterior of the housing 1, the interior and exterior of the housing 1 (including the outer clip 31) could instead be made of a single layer. A single layer 3 is made into which the inner clip 32 is placed.

Although the embodiments of the housing 1 shown in the figures are made from two layers 2, 3, they could also be made from a single layer 2 or 3 forming both the inside and the outside of the housing 1.
