Laptop Bag with Sun-Shading Function

The present disclosure relates to the technical field of luggage and bags, particularly to a laptop bag with a sun-shading function.

Due to the advantages of light weight, compact size, and portability, laptops and tablets have been widely used in both work and study.

When using a laptop outdoors or under strong lighting, the ambient brightness often exceeds that of the display screen, making it difficult to see the content on the screen. Manually increasing the screen brightness can harm the eyes, so there is a need to design a product with shading functionality to address this issue.

U.S. Pat. No. 9,310,615 discloses a sun-blocking hood for electronic devices, the hood or shade includes a left, right, top, and back panel that may be various configured so as to fully collapse the hood or fully construct the hood so as to provide privacy and shading to the display of an electronic device. The hood is height adjustable, via side extenders that are attached to the top panel and that overlap the left or right panels. In the collapsed position, the hood may be attached to the electronic device so as to provide protection to the outside of the electronic device. However, this product must be attached to the display to function, cannot be used to store a laptop, and its side panels may interfere with keyboard operation.

Chinese Patent Document CN2702354Y discloses a computer handbag, the shield of the computer bag and combination of computer and handbag, which makes the laptop computer concealed and shadows the light directly irradiating on the computer screen. The handbag which can move between an open position and an off position comprises an upper top, a lower bottom and a baffle smoothly situated at the inner surface of the upper top of the handbag. The baffle can axially pivots at the upper top to form a reverse U-type shield which supports the inner surface of the lower bottom of the handbag. The upper top, the lower bottom and the baffle of the handbag form a five-side cavity with the sixth surface opened for user to browse the computer screen. The design of this handbag allows it to carry a laptop and features a top section that can shield the screen from sunlight. However, there are some drawbacks to this design: the bag lacks a dedicated padded compartment for securing the laptop during storage, which means the device may easily slip out when the bag is opened, potentially causing damage; in addition, the bending sections lack transition segments, making it cumbersome to collapse and close the handbag properly; additionally, the sealed compartments formed by the side panels create enclosed spaces, leading to inadequate heat dissipation for the laptop.

Therefore, there is a need to design a new laptop bag to address these technical issues.

The present disclosure aims to solve the technical problems of existing sunshades or shading-enabled carrying cases, such as unreliable laptop storage, lack of ventilation channels for the computer, and inconvenient folding of side panels or closing of the case.

To address the above technical issues, the present disclosure provides a laptop bag with a sun-shading function, comprising a first package and a second package that are rectangular in shape and made of a flexible first layer group, wherein edges of the first package and/or the second package are provided with sides of a certain height, and the corresponding edges of the first package and the second package are fixedly connected through the sides to form a handle section.

A flexible second layer group is stitched inside the first package, forming a storage pocket with an opening, wherein the opening of the storage pocket faces the handle section.

A left support plate and a right support plate made of a rigid third layer group are stitched on two side faces of the second package adjacent to the handle section, and bottom edges of the left support plate and right support plate are inclined, such that when the left support plate and right support plate are unfolded and stand upright on the first package through front sides thereof, gaps are formed between rear sides of the support plates and the first package.

A top plate made of a rigid third layer group is stitched on a side of the second package opposite to the handle section, and the top plate is capable of rotating relative to the second package; both sides of the top plate extend outward to form a left wing plate and a right wing plate respectively, with a left transition section formed between the top plate and the left wing plate and a right transition section formed between the top plate and the right wing plate.

Hook sides of Velcro are fixedly arranged on upper outer parts of both the left support plate and right support plate, and the left wing plate and right wing plate are detachably connected to the hook sides of Velcro respectively.

The first package and the second package are opened and closed through a zipper stitched on the sides.

This solution ensures stable storage of the laptop through the storage pocket, preventing damage caused by slipping. The inclined bottom edges of the left support plate and right support plate make their front sides higher than the rear sides, allowing the rear sides to avoid the sides and preventing the second package from tilting forward. The gap between the rear sides of the support plates and the first package facilitates heat dissipation from the laptop, preventing overheating during prolonged outdoor use in high temperatures. The left and right transition sections prevent rigid right angles from causing harm to the body and allow the wing plates to fold inward more easily when closing the bag. Additionally, these transition sections enable larger rounded corners at the edges of the first and second packages, simplifying production and enhancing the bag's aesthetic appeal.

The present disclosure further provides a sunshade tablet package, comprising a first package and a second package that are rectangular in shape and made of a flexible first layer group, wherein edges of the first package and/or the second package are provided with sides of a certain height, and the corresponding edges of the first package and the second package are fixedly connected through the sides to form a connecting section.

A diagonal support plate made of a rigid third layer group is stitched on a side of the second package opposite to the connecting section, the diagonal support plate is capable of rotating relative to the second package, and a left support plate and a right support plate made of the third layer group are respectively rotatably arranged both sides of the diagonal support plate.

A main connecting plate is arranged at a bottom of the diagonal support plate, and the main connecting plate is provided with a protrusion, such that by connecting the main connecting plate to the first package, the diagonal support plate is inclinedly positioned on the first package to support a tablet, wherein the protrusion is configured to block the tablet to prevent the tablet from slipping.

A top plate made of a rigid third layer group is also stitched on a side of the second package opposite to the connecting section, and the top plate is capable of rotating relative to the second package; both sides of the top plate extend outward to form a left wing plate and a right wing plate respectively.

Hook sides of Velcro are fixedly arranged on upper outer sides of both the left support plate and the right support plate, and the left wing plate and the right wing plate form detachable connections with the hook sides of Velcro on the outer sides of the left support plate and the right support plate respectively.

In this solution, by connecting the main connecting plate to the first package, the diagonal support plate can be inclined on the first package. The protrusion is used to block the tablet, allowing the tablet to lean against the diagonal support plate during use. Due to the protrusion, the tablet is less likely to slip, freeing the hands for easier operation. The top plate, which is capable of rotating relative to the second package, adjusts its relative position to the left support plate and right support plate through the left wing plate and right wing plate, thereby adjusting the height of the top plate and the amount of light entering the display. This accommodates users of different heights and adapts to various external lighting conditions.

The following provides a further detailed description of the present disclosure with reference to the drawings and specific embodiments.

As shown in, a laptop bag with a sun-shading function includes a first packageand a second packagethat are rectangular in shape and made of a flexible first layer group.

On the edges of the first packageand/or the second package, there are sideswith a certain height. The corresponding edges of the first packageand the second packageare fixedly connected through these sidesto form a handle section

As shown in, the first layer group sequentially includes, from outside to inside, a fabric layer, a sponge layer, and a flannelette layer. The edges of the fabric layer, the sponge layer, and the flannelette layerare covered with edge-binding tapesand stitched together.

As shown in, a flexible second layer group is stitched to the inner side of the first package, forming a storage pocketwith an opening, where the opening of the storage pocketfaces the handle section

The second layer group includes one or more flannelette layers. In this embodiment, the second layer group consists of two flannelette layers, with a thin sponge layersandwiched between the two flannelette layers. Three edges of the second layer group are all stitched to the first package

The first packageis equipped with an elastic strap. One end of the elastic strapis covered by the edge-binding tapeon the first packageand stitched to the first package, while the other end of the elastic strapextends to the outer surface of the storage pocket. A hook side of Velcrois stitched on the elastic strapat the end extending into the storage pocket, allowing the elastic strapto be adhered directly to the storage pocket. This way, when a laptop is placed in the storage pocket, the elastic strapcan partially close the opening, effectively preventing the laptop from slipping out.

As shown in, on both side faces of the second packageadjacent to the handle section, a left support plateand a right support platemade of a rigid third layer group are stitched. The bottom edges of the left support plateand the right support plateare inclined, such that when the left support plateand the right support plateare unfolded and stand upright on the first packagethrough their front sides, gapsis formed between the rear sides of the left support plateand the right support plateand the first package. The inclined bottom edges of the left support plateand the right support plateensure the front sides of the left support plateand the right support plateare higher than the rear sides, allowing the rear sides to avoid the sideand preventing the second packagefrom tilting forward. Gaps are formed between the rear sides of the left support plateand the right support plateand the first package. The gapsfacilitates the dissipation of heat generated by the laptop, preventing overheating during prolonged outdoor use in high temperatures.

Since the structures of the left support plateand the right support plateare identical, the right support plateis used as an example to illustrate the specific structure of the third layer group in.

The third layer group sequentially includes, from outer to inner, a fabric layer, a rigid plastic plate, and a flannelette layer. The edges of the fabric layer, the rigid plastic plate, and the flannelette layerare covered by edge-binding tapesand stitched together. Since the left support plateand the right support plateneed to withstand pressure from the top plate, a rigid plastic plateis placed between the fabric layerand the flannelette layer

The left support plateand the right support plateeach have a flexible first connecting sectionto enable folding relative to the second package. The first connecting sectionis formed by outward extensions of the fabric layerand the flannelette layerthat constitute the third layer group. With this setup, the left support plateand the right support platecan be stitched to the second packageduring the stitching of the second package

The inner bottoms of the left support plateand the right support plateare both equipped with flexible connecting platesfor connecting to the first package. The connecting plates are positioned near the front sections of the left support plateand the right support plateto avoid obstructing the gaps

The connecting plateis formed by stitching a fabric layerand the hook side of Velcro. One side of the connecting plateis stitched to the right support plateto enable folding.

As shown in, in this embodiment, the width of the first package is W, the width of the left support plateand the right support plateis W, where ½≤W/W≤¾ to ensure that the left support plateand the right support platecan effectively support the top platewithout interfering with the operation of the laptop keyboard.

As shown in, a top platemade of a rigid third layer group is stitched on the side of the second packageopposite to the handle section. The structure of the third layer group used here is consistent with that forming the right support plate.

The top platehas a flexible second connecting sectionto enable folding relative to the second package. The second connecting sectionis formed by outward extension of the fabric layerand the flannelette layerof the third layer group. With this setup, the top platecan be stitched to the second packageduring the stitching of the second package

Both sides of the top plateextend outward to form a left wing plateand a right wing plate. A left transition sectionis formed between the top plateand the left wing plate, and a right transition sectionis formed between the top plateand the right wing plate

In this embodiment, the left wing plate, the left transition section, the top plate, the right transition section, and the right wing plateare configured as whole, allowing the left wing plate, left transition section, the right transition section, and the right wing plateto be formed by pressing four creases on the rigid plastic plateand bending.

The configuration of the left transition sectionand the right transition sectionprevents the hard right angles from causing harm to the body and also allows the left wing plateand the right wing plateto fold inward more closely, making it easier to close the laptop bag. Additionally, with the left transition sectionand the right transition section, the first packageand the second packagecan form larger rounded transitions at the corners, facilitating production and enhancing the aesthetic appearance of the laptop bag.

As shown in, the upper outer sides of the left support plateand the right support plateare both fixed with the hook sides of Velcro. Meanwhile, since the inner layers of the left wing plateand the right wing plateare flannelette layers, when the left wing plateis pressed onto the left support plateand the right wing plateis pressed onto the right support plate, they can form a detachable connection with the hook sides of Velcro. This allows adjusting the pitch angle of the top platebased on the user's height and outdoor light intensity to control the amount of light reaching the display, making the laptop bag highly adaptable.

As shown in, in this embodiment, the sideis located on the second package. When the top plateis adjusted to a higher position, the ends of the left transition sectionand the right transition sectionnear the second packagemay move away from the second package, potentially creating light-leaking gaps. Positioning the sideon the second packageallows the sideto cover these gaps and prevent light leakage.

As shown in, the first packageand the second packageare opened and closed through a zipperstitched along the side

As shown in, a mesh fabric is stitched to the inner side of the second packageto form a document pocketwith an opening. The opening of the document pocketfaces the handle section, and a hook side of Velcrois provided on the inner surface of the mesh fabric at the opening. In this embodiment, the depth of the document pocketis configured to be ≥210 mm to fully accommodate A4 paper.

As shown in, the front ends of the left wing plateand the right wing plateare chamfersto prevent the corners of the left wing plateand the right wing platefrom protruding and harming the user when the top plateis raised.

Elastic strapsare stitched to the outer side of the left wing plateand the right wing platefor hanging stationery such as pens.

As shown in, a handleis provided on the outer side of the handle section.

In this embodiment, the rigid plastic plateis made of PP plate sheet, though lightweight materials with sufficient strength such as PE plate sheet may also be used; the fabric layeris made of CDYarn; the flannelette layeris made of velvet; the edge-binding tapeis made of nylon-like edge-binding tape; and the mesh fabric is circular hexagonal mesh fabric.

As shown in, a tablet bag with a sun-shading function includes a first packageand a second packagethat are rectangular in shape and made of a flexible first layer group.

The edges of the first packageand/or the second packageare provided with raised side, and the corresponding edges of the first packageand the second packageare fixedly connected through the sidesto form a connecting section

The first layer group consists of, from outer to inner, a fabric layer, a sponge layer, and a flannelette layer. The edges of the fabric layer, the sponge layer, and the flannelette layer are covered with edge-binding tapes and stitched together. The structure of the first layer group is consistent with that in Embodiment 1, and its specific details are not repeated here.
