a illustrates in perspective view a second embodiment of an exemplary universal carrying case for a second type of electronic device; wherein
Exemplary embodiments of specific purpose carrying cases for portable electronic devices and other items are disclosed herein that overcome numerous problems and disadvantages of conventional carrying cases for such devices and items. In order to understand the invention to its fullest extent, the following disclosure will be segmented into different parts, wherein Part I discusses problems and disadvantages common to conventional carrying cases for electronic devices and other items; and Part II discloses exemplary embodiments of carrying cases of the present the invention that overcome the problems and difficulties disclosed in Part I.
I. Introduction to the Invention
Specific purpose carrying cases for various items are known and are in widespread use. A notable example of specific purpose carrying cases include protective travel cases for electronic devices.
Carrying cases for portable electronic devices such as laptop and notebook computers, personal digital assistant (PDA) devices, digital cameras, cellular phones, and personal music and entertainment devices such as video game systems, compact disc players, digital video disk (DVD) players, and personal music systems, are known. The cases define a storage compartment that generally surrounds an electronic device, and the cases may provide for storage of power cords, batteries, and accessories that are usable with the device. Such cases provide convenient storage for electronic items during periods of non-use, as well as a convenient travel bag for electronic items and accessories. The cases often include padding and the like to isolate the electronic device from mechanical shock and impact while the case is being carried, therefore providing some degree of protection from impact forces that may otherwise damage the device as it is carried in the case from place to place, loaded to and from vehicles and aircraft, and when being picked up and set down by a user.
Conventionally, carrying cases for portable electronic devices are typically custom designed for devices having a particular size. That is, carrying cases are typically sized and dimensioned to fit a specific type, style of model of electronic device. The cases are typically sold separately from the electronic devices with which they are to be used. Obtaining the appropriate carrying case for an electronic device can be inconvenient, expensive, and burdensome. It can be difficult to find a case that properly fits certain electronic devices.
Additionally, many users of portable electronic devices own and/or use a given electronic device for a relatively short period of time. As technology progress for portable electronic devices, existing devices can quickly become outdated and undesirable. Consequently, they are routinely replaced by other, newer electronic items. Because the physical dimensions of the electronic devices are subject to change, the odds of purchasing a new device that will properly fit into a conventional carrying case for an older device are low.
Conventional carrying cases for electronic devices are typically fabricated from semi-rigid materials to provide structural strength for carrying of the case and to protect an electronic device against occasional bumps and impact that may occur, for example, when loading the case to and from an automobile or aircraft. The rigidity of known cases is a practical constraint on their ability to accommodate electronic devices having dimensions different from the device for which the case was designed. Smaller devices will not fit snugly in the case and may consequently be more prone to breakage, while larger devices will not fit into the case at all. As one example, laptop and notebook computers vary considerably in their exterior dimensions and weight, both for new computers and existing computers, rendering certain computers incompatible with certain carrying cases, and vice versa. Consequently, many known carrying cases tend to become obsolete along with their associated electronic devices, and often may be simply discarded.
Aside from the issues noted above, conventional carrying cases are disadvantaged from a thermal perspective. Many electronic devices, including but not limited to laptop or notebook computers, for example, become warm to the touch in use, and in prolonged use may generate much heat. When used just before being placed into a carrying case, as they typically are, laptop and notebook computers, as well as other devices, are typically warm at the time they are packed into the carrying case. Conventional bags, however, are not designed to dissipate this heat, and instead trap the heat within the case. This is undesirable and may in part cause the electronic device to overheat, potentially causing reliability and performance issues for the device.
While the aforementioned problems and difficulties are described in the context of carrying cases for portable electronic devices, such problems and difficulties are not necessarily unique to portable electronic devices Similar problems exist in transporting other items, whether electronic or otherwise, and whether portable or non-portable, from place to place.
II. Exemplary Embodiments of Inventive Carrying Cases
Embodiments of protective carrying cases for electronic devices and other items are disclosed herein that may be more universally used amongst electronic devices and items having different external dimensions, and that also may dissipate heat more effectively than known carrying cases. As such, and unlike conventional carrying cases for electronic devices, for example, the carrying cases of the invention may capably accommodate electronic devices having different external dimensions and physical size. In one example, embodiments of a carrying case for laptop or notebook computers are provided that accommodate a range of sizes of computers that may vary up to three inches in external dimension, for example, from one another. The carrying cases are stretchable and generally self-conforming to various sizes of electronic devices, and also allow the electronic device to breathe and dissipate heat in the manner described below. Embodiments of carrying cases are also disclosed for other types of electronic devices, as well as other items that are not electronic.
The carrying case 100 may include a generally rectangular body having a front or first panel 104, a rear or second panel 106 spaced from the first panel 104, side panels 108 and 110 that interconnect the front and rear panels 104 and 106 at opposing edges thereof, and a bottom panel 112 that connects lower edges of the front and rear panels 104 and 106. One end or edge of the case 100 defines an opening or compartment 114 through which the electronic device 102 may be inserted. A closure strap or tether 116 may be provided over a portion of the opening 114 and may extend between the front and rear panels 104 and 106. A first end of the strap 116 may be stitched or sewn, for example, to the rear panel 106, and the second end of the strap 116 and the front panel 104 may be provided for example, with hook and loop fasteners to removably secure the strap 116 across the opening 114 when the electronic item 102 is packed therein.
The case 100 may be fabricated in whole or in part from elastic materials that allow the case 100 to stretch around and conform to the electronic device 100. As used herein, an elastic material shall refer to a material that is generally deformable under load and that returns to its original shape when the load is removed. That is, an elastic material possesses the capability to stretch, expand, or deform to endure large mechanical strains when stressed, without permanent deformation of the material.
As shown in
In one embodiment, the panels used to form the case 100 are thin walled and are generally flexible so that, for example, the case 100 may be folded flat when not in use. Notably, however, because of the elastic materials used to fabricate the panels of the case 100, the case 100 is elastic, expandable, or stretchable in the width dimension WC, in the height dimension HC, and in the depth dimension DC. In contrast to conventional carrying cases, none of the width, height, or depth dimensioned are constrained by rigid or semi-rigid materials that prevent expansion of the bag beyond the dimensions WC, HC, and DC. Accordingly, via the elasticity of the panels in the case 100, the internal volume of the compartment 114 is expandable in a self conforming manner to match the volume required by the device 102.
The electronic device 102 may include a generally rigid, and in the illustrated example, a generally rectangular housing 120 that contains and protects sensitive electronic components that enable the functionality of the device 102. The housing 120 may include a front surface 122, a rear surface 124 opposing the front surface, front and rear edges 126, 128, and left and right side edges 130, 132. The device 102 may include first and second portions coupled to one another by hinges 134, 136 at the rear edge 128, for example. While the device 102 is illustrated in a compact collapsed position wherein the two portions of the device 102 meet at a parting line 138, the device 102 may be unfolded about the hinges 134, 136 to an operating position wherein a user is presented with, for example, a display, input selectors such as a keyboard or cursor control, touch sensitive keypads, and other input means known in the art for use and control of the device 102. The device 102 may also include one or more speakers or audio devices, a microphone, and various signal ports and connecting ports to facilitate communication between the device 102 and other electronic devices and accessories. The device 102 may also include one or more batteries which may be rechargeable, a processor, and memory storage for use by the device.
In various embodiments, the device 102 may be a laptop or notebook computer, on another type of electronic device such as, for example only, a personal digital assistant (PDA) device, a digital camera, a cellular phone, and a personal entertainment device such as a video game system, a compact disc player, a digital video disk (DVD) player, and a personal music systems such as an MP3 player. Other hand-held and portable electronic devices are also known that may benefit from the carrying case of the invention, including, for example, video cameras, calculators, sound systems such as satellite radio modules and the like that are removable from a vehicle, weather stations and radios, fish finders, global positioning systems, mapping and travel aid devices, travel clocks and travel alarms, calculators, digital photo frames and displays, electronic books, toys, and tools having processor-based functionality and electronic features. The foregoing examples of electronic devices are provided for purposes of illustration rather than limitation, and all such devices and other devices may benefit from the case 100. While
As illustrated in
The elasticity of one or more of the panels of the case 100 may stretch around and generally conform to the housing 120 of the electronic device 102. In other words, the case 100 will expand in the width and depth dimensions to and assume the external shape and dimension of the electronic device 102 as the device 102 is inserted into the case 100 through the opening 114. The opening 114, by virtue of the elastic panels, is sometimes referred to as a variable volume opening or compartment that may expand and contract to varying degrees dependent upon the dimensions of the device 102 received within the compartment 114. The height dimension He of the device 102 may also be greater than the height dimension HC of the case 100, and the case 100 may stretch in the height dimension, in addition to the width and depth dimensions. Because of the elasticity of the panels in the case 100, the case 100 may receive devices 102 that vary in one or more of the width, depth and height dimensions by several inches.
In one example, the case 100 may accommodate a range of laptop or notebook computers from so-called 12 inch to 15 inch models having displays of corresponding size. In another embodiment the case 100 may accommodate a range of laptop or notebook computers from so-called 15 inch to 17 inch models having displays of corresponding size. The ability of the case 100 to expand to fit 12-15 inch computers or 15-17 inch computers, for example, is dependent upon the original dimensions of the case 100 in the relaxed or unexpanded state, and the particular materials or fabrics used to form the panels of the case 100. Depending on the particular materials used, the elasticity of the panels of the case 100 may possess varying degrees of elasticity before stresses induced in the materials reach their yield strength wherein permanent deformation of the panels will occur.
Not only may the case 100 fit a range of notebook computers from 12 inch models to 17 inch models, but the case 100 may accommodate varying dimensions of laptop or notebook computers having a particular size display. That is, the external dimensions We, He, and De of a particular 12 inch notebook computer, for example, of one manufacturer may vary from another 12 inch notebook computer of another manufacturer. Also, the external dimensions We, He, and De of one model of a 12 inch notebook computer, for example, may vary from the dimensions We, He, and De of another model of the same manufacturer. Despite such dimensional differences, however, the case 100 may be more or less universally used with a large number of notebook computers that conventionally would require multiple and different carrying cases for computers of different sizes.
Each panel 104 and 106 may be fabricated from a base layer 150 of material or fabric having elastic or stretchable properties that may expand and contract around the electronic device 102 (
The side and bottom panels 108, 110, and 112 (
In the example illustrated in
By virtue of the material 152 the case 100 may, for example, be placed within another bag such as a briefcase or portfolio while providing some mechanical isolation of the electronic device 102 from impact when the device 102 is contained in the case 100, or may provide mechanical isolation and shock protection when the case is set upon a hard surface, such as a counter, desk or tabletop, by a user. Aside from shock absorbent properties, the material 152 may be selected to have elastic properties as well, and the properties of the materials 152 may be substantially equal to those of the base layer 150. In another embodiment, the material 152 may have different elastic properties as the base layer 150 but because the portions of material 152 are spaced apart from one another with at least a strip of the base layer material 150 extending therebetween, the panels 104 and 106 retain a degree of elasticity via the base layer 150 that may stretch at a location between the materials 152.
In the illustrated embodiment, the panels 104 and 106 each include a central portion provided with a mesh material 154 that extends between and across the interior portions of the C-shaped shock-absorbent materials 152. The mesh material 154 in the central portion, like the elastic base layer 150 also has elastic properties that allow it to expand in the width and height dimensions, for example. Unlike the base layer 150 that is of a generally closed and solid construction, the mesh material 154 is provided with a generally open construction having a number of ventilation openings 156 that expose the front and rear surfaces 122 and 124 (
The mesh material 154 may be stitched or sewn, for example, to the base layer 150 and/or the shock-absorbent materials 152, or may be otherwise attached or coupled to the base layer 150 and the material 152 using techniques known in the art, including but not limited to lamination techniques known in the art. A variety of mesh materials or net materials are known that are suitable for the panels 104 and 106, any of which may be selected to achieve specific elasticity objectives and to provide sufficient heat dissipation and breathability for the electronic device.
Various adaptations of the case 100 are believed to be within the purview of those in the art without departing from the scope and spirit of the invention. For example, the shock absorbent materials 152 may be omitted in alternative embodiments, and as another example one or more ventilation openings could be formed in the base layer 150 without the use of the mesh material 154. Instead of constructing the panels 104 and 106 from multiple and different materials as described, the panels 104 and 106 may be formed from a single material if desired in one or more layers to accomplish similar effects. Varying degrees of stiffness may be provided in the panels of the case 100 depending on the actual materials used, while still exhibiting elastic behavior to accommodate different electronic devices 102.
Additionally, the shock-absorbent material 152 and the mesh material 154 in another embodiment may be provided in one or the other, but not both of the front and rear panels 104 and 106. The front and rear panels 104 and 106, for example, need not be fabricated from the same materials and need not have the same elastic properties in some embodiments of the invention to achieve at least some of the benefits of the invention. Different materials may be selectively used to vary the elastic behavior of the case in the width, depth, and height dimensions, and the elasticity of the case in the width dimension, for example, may be greater than the elasticity in the depth dimension, with the elasticity of the height dimension being different from each of the width and depth dimensions. That is, the case 100 may be constructed to conform or stretch more easily to fit one dimension of the electronic device, such as the width dimension, than another dimension of the device, such as the depth dimension in one example.
The case 100 can be easily carried in one hand, tucked under an arm or placed in a brief case, portfolio, a backpack or another bag without taking up an undue amount of space. That is, the compact carrying case 100 may be manually carried as a stand alone case, or placed within another piece of baggage such as a brief case, a portfolio, or another baggage item. When the case 100 is used within another piece of baggage, the other piece of baggage may be fabricated from rigid or semi-rigid materials and which may be provided with padding layers, cushioning members, and the like to provide additional protection to an electronic device. U.S. Pat. No. 6,691,843 that is commonly owned with the present application, discloses one cushioning system for a case-within-a-case combination that may be effectively used with the inventive carrying cases described herein.
Additionally, one or more pockets for accessories and the like to be used with an electronic device may be integrated into the construction of the case 100, and carrying handles, shoulder straps, harnesses, and the like may be provided for the user's convenience in transporting the case. Clips, belts, buckles, straps, and other connecting structure may be provided to connect or couple the case 100 to another baggage item. Zippers and other closure mechanisms may be provided in the case 100 if desired. Various colors, graphics and indicia may be provided on one or more panels of the case to differentiate devices and items of various manufacturers from one another, or as a means to personalize the carrying case for a consumer or purchaser. Still other adaptations are possible.
Also like the case 100, and as shown in
Also like the cases 100 and 200, and as shown in
The panel or panels 404 may include, as shown in
While exemplary devices and items have been described in connection with various exemplary embodiments of the invention, it is understood that the devices and items disclosed herein are exemplary only, and that embodiments of carrying cases and sleeves may be adapted for other devices and items without departing from the scope and spirit of the invention.
Still, further, embodiments of carrying cases may be provided for devices and items that are not hand held or portable devices. For example, elastic cases as described may be provided on a larger scale and may be used, for example, when moving large screen televisions, flat panel displays, and computer equipment from one place to another. The elastic panels of the cases may fit a range of televisions, displays, and computer equipment that vary in dimension from one another, for example, and the ventilation openings that allow the items to breathe when in the cases may be beneficial to the transport of such devices in the back of a moving truck, for example. Additionally, the shock absorbent padding may provide necessary protection, and even may provide for stackability of certain items upon one another in a truck or other vehicle without damaging the devices.
The cases of the invention may also be beneficial for retailers and distributors as electronic products and items are moved about a facility. The cases may be provided and installed at a manufacturer's facility if desired, and may be removed and reused by other parties as desired. Benefits are therefore provided at the manufacturer level, the distributor level, the retailer level, and the consumer level.
Using the embodiments of cases 100, 200, 300 and 400, a method 500 for transporting an item an item having an external size is illustrated in
The sleeve may be provided 502 at the manufacturer lever, the distributor level, the retailer level, or the end user or consumer level in various embodiments of the method 500. More than one sleeve may be provided 502 if desired to transport more than one item at the same time. For example, an inventory of sleeves of different sizes and shapes may be provided and used, for example, by moving companies to transport a host of household electronic items of different types and sizes, whether hand-held or not, in a moving truck. Manufacturers, distributors and retails may use the sleeves similarly. As another example, the owner of multiple hand-held devices may possess a first sleeve to transport a notebook computer, a second sleeve to transport a PDA device, and a third sleeve to transport a digital camera, with each of the sleeves being capable of accommodating a range of respective devices of different sizes. As still another example, a host or hostess may possess a number of sleeves similar to the sleeve 400 of the same or different initial sizes for accommodating various sizes and dimensions of beverage bottles, beverage cans, cups, glasses and other containers for use by guests at a party.
Transporting 508 the item may include, for example, in different embodiments, a user carrying the sleeve by hand or under an arm, carriage of the sleeve by a person with a carrying handle or strap, transporting of the sleeve containing the item in another container such as a moving or shipping box, moving the sleeve within a general purpose bag carried by a person, transporting the sleeve in wheeled towable baggage, fastening of the sleeve to another bag that is carried by a person, moving one or more of the sleeves on a wheeled cart, or carriage of the sleeves in a truck, boat, vehicle or aircraft.
When item arrives at its destination in the sleeve, the sleeve may be unsecured 510 by opening or releasing the closure element, and the sleeve may be removed 512 by sliding the sleeve back over the item. When the sleeve is removed from the item, it resiliently returns to its original size and is ready for reuse with the same item or another item of different size or external dimension. The item is available for use 514 after the sleeve is removed.
The benefits of the invention are now believed to be amply demonstrated by the exemplary embodiments disclosed.
While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
