  • invention or "present invention” as used herein is a non-limiting term and is not intended to refer to any single embodiment of the particular invention but encompasses all possible embodiments as described in the application.
  • FIGS. 1-5 illustrate a storage case 100 according to an embodiment.
  • Storage case 100 can be a protective case, sleeve, bag, etc. for an electronic device.
  • storage case 100 may be referred to generally herein as a "laptop bag”
  • storage case 100 can be configured to carry a variety of electronic devices, for example, but not limited to, a laptop computer, phone, tablet, or any other portable electronic device.
  • storage case 100 may be configured to carry other portable articles that may require the protective features described herein.
  • Some laptop bags include protective elements, for example, padding, to protect the laptop from damage during transport.
  • Some bags have a soft base with foam to protect the laptop when it is placed into the bag or when the bag is placed or dropped on a hard surface.
  • these bags have at least two sides and a separate base forming a flat bottom between at least two vertical sides.
  • These bags also typically have separate, flat side portions.
  • the bags are therefore generally rectangular in shape. Manufacturing bags of this type is costly and involves many steps for production and inserting foam in the base. Each edge of the base must be attached to the sides of the bag, requiring multiple seams along the bottom of the bag. The flat bottom also makes these bags wider and more bulky for the carrier.
  • embodiments of the storage case 100 provide one or more advantages over these and other types of laptop bags.
  • embodiments of storage case 100 are easier and less expensive to manufacture than some laptop bags because it eliminates the flat bottom. This reduces the number of seams required to assemble the bag. Rather than needing up to four seams to attach a padded rectangular base, the bottom of storage case 100 can be attached with just a single seam 220 in some embodiments. This can simplify the manufacturing process. This design also reduces the size of the bag, thereby making it smaller and lighter to carry.
  • protective bumper 200 is disposed between front panel 110 and back panel 120 of storage case 100. As shown, for example, in FIG. 1 , in certain embodiments protective bumper 200 can be a cylindrical piece of foam disposed along the bottom of storage case 100. When an electronic device is placed into storage case 100, protective bumper 200 can cushion the device and protect the edges of the device. Protective bumper 200 can also reduce the impact on the device if it is dropped into storage case 100, or if storage case 100 itself is dropped. For example, if storage case 100 is dropped on the ground, protective bumper 200 can dampen the vibration and provide cushioning to the electronic device to prevent damage. This is important for electronic devices, which often include small and/or sensitive components that are susceptible to breaking if dropped. For example, a laptop screen could crack if the laptop is dropped on the ground. Protective bumper 200 reduces this risk of breakage.
  • protective bumper 200 within storage case 100 is also improved over bags with flat padded bottoms.
  • protective bumper 200 can include a sleeve 204 that can be wrapped around cushioning member 202.
  • Sleeve 204 can have an attachment element 210 that extends below cushioning member 202 and can be attached to the bottom edges of front panel 110 and back panel 120 along a single seam 220. In some embodiments, this single seam may allow for quick, simple assembly, thereby reducing production costs.
  • cushioning member 202 can also have a stem 212 extending below cushioning member 202, which can be directly attached to front panel 110 and back panel 120 along seam 220. This can also simplify the manufacturing and assembly process of storage case 100.
  • cushioning member 202 of protective bumper 200 can have a first wing 214 and a second wing 216 configured to prevent the electronic device from slipping into a space between protective bumper 200 and the front and back panels 110, 120.
  • cushioning member 202 can have a curved surface to cradle the electronic device inside storage case 100. This can further protect the electronic device from sliding or moving around inside storage case 100.
  • FIG. 1 illustrates a cross-section of storage case 100 according to an embodiment.
  • storage case 100 can include front panel 110 and back panel 120.
  • Front panel 110 and back panel 120 can be various shapes and sizes, for example, square or rectangular.
  • front panel 110 and back panel 120 can have curved corners.
  • front panel 110 and back panel 120 can be the same shape and size.
  • front panel 110 and back panel 120 can be different shapes and sizes.
  • the shape and size of storage case 100 can be configured to hold electronic devices of standard sizes.
  • storage case 100 can be configured to hold a 15-inch laptop, although many other sizes are contemplated.
  • the size and shape of certain embodiments of storage case 100 can be configured to hold a specific electronic device, for example, an iPad made by APPLE INC.
  • Front panel 110 and back panel 120 can be a single layer of material or one or both of these components can be multi-layered.
  • front panel 110 and back panel 120 can each include outer layer 160, inner lining 164, and padding layer 162.
  • Different materials can be used for outer layer 160, inner lining 164, and padding layer 162.
  • Materials other than those disclosed herein for outer layer 160, inner lining 164, and padding layer 162 are contemplated and the materials are not limited to the examples disclosed herein.
  • outer layer 160, inner lining 164, and/or padding layer 162 can include multiple materials.
  • outer layer 160 can have a patchwork design made from different materials.
  • padding layer 162 can be made of a foam material.
  • padding layer 162 can be a polyethylene (PE) foam.
  • PE polyethylene
  • Other padding and cushioning materials for example, polystyrene or composite materials, can also be used.
  • the thickness of padding layer 162 can be adjusted to provide more or less padding.
  • padding layer 162 can be about 1-10 mm thick. In one embodiment, padding layer 162 is about 5 mm thick.
  • Outer layer 160 and inner lining 164 can be woven or non-woven materials. Outer layer 160 and inner lining 164 can be natural, synthetic, or composite materials of varying stiffness, flexibility, durability, etc.
  • outer layer 160 can be canvas, leather, cloth, polyester, or any other material.
  • inner lining 164 can be polyester.
  • a protective bumper 200 can be located within an interior 150 of storage case 100 between interior surface 170 of front panel 110 and interior surface 172 of back panel 120. In certain embodiments, protective bumper 200 can contact interior surfaces 170 and 172. Generally, protective bumper 200 runs along a length of storage case 100 at the bottom of storage case 100. Protective bumper 200 can run along the entire length or only part of the bottom of storage case 100.
  • Protective bumper 200 is configured to cushion and protect an electronic device that is inside storage case 100. For example, if a laptop is dropped into storage case 100, protective bumper 200 cushions the laptop as it hits the bottom of storage case 100. In particular, protective bumper 200 can protect the edges of the laptop from dents or scratches. Protective bumper 200 also reduces the impact and dampens vibrations as the laptop hits the bottom of storage case 100, thereby protecting the components of the laptop from damage. Similarly, if storage case 100 itself is dropped, protective bumper 200 cushions the electronic device from the impact.
  • protective bumper 200 includes a cushioning member 202.
  • Cushioning member 202 can be a variety of shapes, sizes, and materials. For example, as illustrated in FIG. 1 , in certain embodiments, cushioning member 202 can have a cylindrical shape. Using a cylindrical shape has the advantage being easily produced, for example, by extruding a material for cushioning member 202.
  • cushioning member 202 can be tubular, having a hollow interior space. Cushioning member 202 can also be square, rectangular, triangular, hexagonal, or any other shape including a free-form shape.
  • cushioning member 202 can be a sideways "C" shape or "V" or "Y” shape, configured to cradle the electronic device.
  • cushioning member 202 is made from a material that provides cushioning to the electronic device and dampens vibrations when the electronic device hits the bottom of storage case 100 or when storage case 100 is dropped.
  • cushioning member 202 can be made from a foam material.
  • cushioning member 202 can be made from polyethylene (PE) foam.
  • PE polyethylene
  • Other padding and cushioning materials for example, polystyrene or composite materials, can also be used.
  • Cushioning member 202 can be formed, for example, by extruding, injection molding, blow molding, knitting, or other manufacturing processes. For example, a piece of material can be cut, shaved, shaped, etc. to form cushioning member 202.
  • cushioning member 202 can be based on the size of storage case 100. Generally, cushioning member 202 can extend along an entire length of the bottom of storage case 100. In certain embodiments, cushioning member 202 extends only along part of the length of storage case 100. In certain embodiments, multiple cushioning members 202 can be used, each extending along part of the length of storage case 100. Generally, cushioning member 202 is configured to fit between front panel 110 and back panel 120 and to minimize and space between cushioning member 202 and the front and back panels 110 and 120. In certain embodiments, cushioning member 202 can contact both front and back panels 110 and 120.
  • the thickness of cushioning member 202 can also be based on the size of the storage case 100 and also, for example, the anticipated size and weight of the electronic device to be stored in storage case 100. For example, if storage case 100 is configured to hold a heavy article, such as a laptop, the thickness of cushioning member 202 may be greater than if storage case 100 is configured to hold a lighter article, such as a tablet. In certain embodiments where cushioning member 202 is cylindrical, the diameter of cushioning member 202 can be about 10 mm. Larger and small diameters for cushioning member 202 are also contemplated. For example, cushioning member 202 can have a diameter between about 5mm to about 30mm.
  • Protective bumper 200 can have an attachment element 210 which extends below cushioning member 202.
  • attachment element 210 can be part of a sleeve 204 which wraps around all or a portion of cushioning member 202.
  • sleeve 204 may extend along the length of cushioning member 202.
  • sleeve 204 may extend partially along the length of cushioning member 202.
  • Sleeve 204 can be made from the same material as inner lining 164 or from a different material.
  • Attachment element 210 can be attached to bottom edges of front panel 110 and back panel 120 to affix protective bumper 200 within interior 150 of storage case 100.
  • seam 220 along the bottom edges of attachment element 210, front panel 110, and back panel 120 can attach these components together.
  • seam 220 can be a stitched seam, for example, sewn using a mechanical sewing device or by hand.
  • seam 220 may comprise a stitchless seam made, for example, by using heat sealing, laminating, adhesives, thermoplastic tape, and other suitable methods.

  • protective bumper 200 can be formed, for example, in a mold, so that its shape has the cross-section shown in FIG. 7 .
  • protective bumper 200 may comprise a "T" or "Y” shape. Variations of this "T" or "Y” shape are also contemplated.
  • the length of stem 212 can vary, but generally stem 212 is long enough so that seam 220 can attach front panel 110, back panel 120, and stem 212.
  • a stitched seam can run through front panel 110, back panel 120, and stem 212 of cushioning member 202.
  • FIG. 7 in some embodiments, there is no sleeve around cushioning member 202. Rather, the seam 220 can run directly through stem 212 to affix protective bumper 200 in place. Therefore, as in the embodiment shown in FIG. 1 , only a single seam 220 is needed to attach front panel 110, back panel 120, and stem 212 to affix protective bumper 200 inside storage case 100.
  • edge binding 230 can cover seam 220 and stem 212 of protective bumper 200.
  • sleeve 204 may be used in conjunction with a cushioning member 202 having a stem 212.
  • cushioning member 202 can include first wing 214 and second wing 216.
  • First wing 214 and second wing 216 can contact interior surface 170 of front panel 110 and interior surface 172 of back panel 120, respectively.
  • first wing 214 and second wing 216 can extend upward along interior surface 170 of front panel 110 and interior surface 172 of back panel 120, respectively. This can provide a curved upper surface of cushioning member 202 to cradle and stabilize the electronic device inside storage case 100.
  • Wings 214 and 216 can also provide a greater surface area to cushion the electronic device. Wings 214 and 216 can also prevent an electronic device placed within storage case 100 from entering a space between protective bumper 200 and front panel 110 or back panel 120. If the electronic device enters this space, rather than resting on protective bumper 200, it may not receive the protective benefits of protective bumper 200.
  • FIG. 8 illustrates a cross-section of storage case 100 according to an embodiment.
  • Front panel 110 and back panel 120 can be the same as described above with respect to FIG. 1 .
  • protective bumper 200 shown in FIG. 8 can include first wing 214 and second wing 216, along with stem 212 extending below cushioning member 202.
  • stem 212 can have protruding portion 218 which extends to an exterior of storage case 100. Protruding portion 218 can be visible from the outside of storage case 100. In certain embodiments, protruding portion 218 can have a wider cross-sectional area than stem 212 of protective bumper 200.
  • Seam 220 can attach front panel 110, back panel 120, and stem 212 of protective bumper 200.
  • no edge binding is used, which can leave protruding portion 218 of protective bumper 200 exposed along an exterior of storage case 100.
  • protruding portion 218 itself can provide exterior protection to storage case 100.
  • FIG. 9 illustrates a top view of interior 150 of storage case 100.
  • protective bumper 200 can run along a length of storage case 100 between interior surface 170 of front panel 110 and interior surface 172 of back panel 120.
  • protective bumper 200 can extend upward along an interior of second side panel 140 and/or first side panel 130.
  • This elongated "U" shape can provide additional protection for the electronic device along the sides of storage case 100. In particular, this can help protect the corners of the electronic device from being damaged and help to further cradle the electronic device within storage case 100.
  • FIG. 10 illustrates storage case 100 according to an embodiment.
  • FIG. 10 shows front panel 110, first side panel 130, and second side panel 140. Additionally, FIG. 10 shows strap 330.
  • strap 300 can be removably attached to storage case 100.
  • strap 330 can attach to one or more attachment points 310 (see FIG. 4 ).
  • attachment points 310 can be located on back panel 120.
  • strap 330 can have hooks, clasps, etc. on one or both ends for attaching to attachment points 310 located on storage case 100.
  • Other attachment mechanisms for strap 330 are contemplated.
  • strap 330 can be an adjustable strap.
