Laptop Bag with Sun-Shading Function

Description

TECHNICAL FIELD

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

BACKGROUND

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.

SUMMARY

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.

DESCRIPTION OF EMBODIMENTS

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

Embodiment 1

As shown in FIGS. 1 to 8, a laptop bag with a sun-shading function includes a first package 11a and a second package 12a that are rectangular in shape and made of a flexible first layer group.

On the edges of the first package 11a and/or the second package 12a, there are sides 13a with a certain height. The corresponding edges of the first package 11a and the second package 12a are fixedly connected through these sides 13a to form a handle section 14a.

As shown in FIGS. 3 and 4, the first layer group sequentially includes, from outside to inside, a fabric layer 15a, a sponge layer 16a, and a flannelette layer 17a. The edges of the fabric layer 15a, the sponge layer 16a, and the flannelette layer 17a are covered with edge-binding tapes 18a and stitched together.

As shown in FIG. 2, a flexible second layer group is stitched to the inner side of the first package 11a, forming a storage pocket 19a with an opening, where the opening of the storage pocket 19a faces the handle section 14a.

The second layer group includes one or more flannelette layers 17a. In this embodiment, the second layer group consists of two flannelette layers 17a, with a thin sponge layer 16a sandwiched between the two flannelette layers 17a. Three edges of the second layer group are all stitched to the first package 11a.

The first package 11a is equipped with an elastic strap 20a. One end of the elastic strap 20a is covered by the edge-binding tape 18a on the first package 11a and stitched to the first package 11a, while the other end of the elastic strap 20a extends to the outer surface of the storage pocket 19a. A hook side of Velcro 26a is stitched on the elastic strap 20a at the end extending into the storage pocket 19a, allowing the elastic strap 20a to be adhered directly to the storage pocket 19a. This way, when a laptop is placed in the storage pocket 19a, the elastic strap 20a can partially close the opening, effectively preventing the laptop from slipping out.

As shown in FIG. 5, on both side faces of the second package 12a adjacent to the handle section 14a, a left support plate 21a and a right support plate 22a made of a rigid third layer group are stitched. The bottom edges of the left support plate 21a and the right support plate 22a are inclined, such that when the left support plate 21a and the right support plate 22a are unfolded and stand upright on the first package 11a through their front sides, gaps 23a is formed between the rear sides of the left support plate 12a and the right support plate 22a and the first package 11a. The inclined bottom edges of the left support plate 21a and the right support plate 22a ensure the front sides of the left support plate 21a and the right support plate 22a are higher than the rear sides, allowing the rear sides to avoid the side 13a and preventing the second package 12a from tilting forward. Gaps are formed between the rear sides of the left support plate 21a and the right support plate 22a and the first package 11a. The gaps 23a facilitates the dissipation of heat generated by the laptop, preventing overheating during prolonged outdoor use in high temperatures.

Since the structures of the left support plate 21a and the right support plate 22a are identical, the right support plate 22a is used as an example to illustrate the specific structure of the third layer group in FIG. 6.

The third layer group sequentially includes, from outer to inner, a fabric layer 15a, a rigid plastic plate 20a, and a flannelette layer 17a. The edges of the fabric layer 15a, the rigid plastic plate 20a, and the flannelette layer 17a are covered by edge-binding tapes 18a and stitched together. Since the left support plate 21a and the right support plate 22a need to withstand pressure from the top plate, a rigid plastic plate 20a is placed between the fabric layer 15a and the flannelette layer 17a.

The left support plate 21a and the right support plate 22a each have a flexible first connecting section 24a to enable folding relative to the second package 12a. The first connecting section 24a is formed by outward extensions of the fabric layer 15a and the flannelette layer 17a that constitute the third layer group. With this setup, the left support plate 21a and the right support plate 22a can be stitched to the second package 12a during the stitching of the second package 12a.

The inner bottoms of the left support plate 21a and the right support plate 22 are both equipped with flexible connecting plates 25a for connecting to the first package 11a. The connecting plates are positioned near the front sections of the left support plate 21a and the right support plate 22a to avoid obstructing the gaps 23a.

The connecting plate 25a is formed by stitching a fabric layer 15a and the hook side of Velcro 26a. One side of the connecting plate 25a is stitched to the right support plate 22a to enable folding.

As shown in FIGS. 3 and 5, in this embodiment, the width of the first package is W1, the width of the left support plate 21a and the right support plate 22a is W2, where ½≤W2/W1≤¾ to ensure that the left support plate 21a and the right support plate 22a can effectively support the top plate 27a without interfering with the operation of the laptop keyboard.

As shown in FIGS. 2 and 7, a top plate 27a made of a rigid third layer group is stitched on the side of the second package 12a opposite to the handle section 14a. The structure of the third layer group used here is consistent with that forming the right support plate.

The top plate 27a has a flexible second connecting section 32a to enable folding relative to the second package 12a. The second connecting section 32a is formed by outward extension of the fabric layer 15a and the flannelette layer 17a of the third layer group. With this setup, the top plate 27a can be stitched to the second package 12a during the stitching of the second package 12a.

Both sides of the top plate 27a extend outward to form a left wing plate 28a and a right wing plate 29a. A left transition section 30a is formed between the top plate 27a and the left wing plate 28a, and a right transition section 31a is formed between the top plate 27a and the right wing plate 29a.

In this embodiment, the left wing plate 28a, the left transition section 30a, the top plate 27a, the right transition section 31a, and the right wing plate 29a are configured as whole, allowing the left wing plate 28a, left transition section 30a, the right transition section 31a, and the right wing plate 29a to be formed by pressing four creases on the rigid plastic plate 20a and bending.

The configuration of the left transition section 30a and the right transition section 31a prevents the hard right angles from causing harm to the body and also allows the left wing plate 28a and the right wing plate 29a to fold inward more closely, making it easier to close the laptop bag. Additionally, with the left transition section 30a and the right transition section 31a, the first package 11a and the second package 12a can form larger rounded transitions at the corners, facilitating production and enhancing the aesthetic appearance of the laptop bag.

As shown in FIG. 5, the upper outer sides of the left support plate 21a and the right support plate 22a are both fixed with the hook sides of Velcro 26a. Meanwhile, since the inner layers of the left wing plate 28a and the right wing plate 29a are flannelette layers 17a, when the left wing plate 28a is pressed onto the left support plate 21a and the right wing plate 29a is pressed onto the right support plate 22a, they can form a detachable connection with the hook sides of Velcro 26a. This allows adjusting the pitch angle of the top plate 27a based 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 FIGS. 7 and 8, in this embodiment, the side 13a is located on the second package 12a. When the top plate 27a is adjusted to a higher position, the ends of the left transition section 30a and the right transition section 31a near the second package 12a may move away from the second package 12a, potentially creating light-leaking gaps. Positioning the side 13a on the second package 12a allows the side 13a to cover these gaps and prevent light leakage.

As shown in FIG. 1, the first package 11a and the second package 12a are opened and closed through a zipper 33a stitched along the side 13a.

As shown in FIG. 5, a mesh fabric is stitched to the inner side of the second package 12a to form a document pocket 34a with an opening. The opening of the document pocket 34a faces the handle section 14a, and a hook side of Velcro 26a is provided on the inner surface of the mesh fabric at the opening. In this embodiment, the depth of the document pocket 34a is configured to be ≥210 mm to fully accommodate A4 paper.

As shown in FIG. 7, the front ends of the left wing plate 28a and the right wing plate 29a are chamfers 35a to prevent the corners of the left wing plate 28a and the right wing plate 29a from protruding and harming the user when the top plate 27a is raised.

Elastic straps 36a are stitched to the outer side of the left wing plate 28a and the right wing plate 29a for hanging stationery such as pens.

As shown in FIG. 1, a handle 37a is provided on the outer side of the handle section. 4a.

In this embodiment, the rigid plastic plate 20a is made of PP plate sheet, though lightweight materials with sufficient strength such as PE plate sheet may also be used; the fabric layer 15a is made of CDYarn; the flannelette layer 17a is made of velvet; the edge-binding tape 18a is made of nylon-like edge-binding tape; and the mesh fabric is circular hexagonal mesh fabric.

Embodiment 2

As shown in FIGS. 9 to 10, a tablet bag with a sun-shading function includes a first package 11b and a second package 12b that are rectangular in shape and made of a flexible first layer group.

The edges of the first package 11b and/or the second package 12b are provided with raised side 13b, and the corresponding edges of the first package 11b and the second package 12b are fixedly connected through the sides 13b to form a connecting section 14b.

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.

As shown in FIG. 9, a flexible second layer group is stitched to the inner side of the first package 11b to form a storage pocket 19b with an opening. The opening of the storage pocket 19b faces one side along the length direction of the first package 11b.

The second layer group includes one or more flannelette layers. In this embodiment, the second layer group includes two flannelette layers, with a thin sponge layer sandwiched between them. All three edges of the second layer group are stitched together with the first package. The structure of the second layer group is consistent with that in Embodiment 1.

The first package 11b is equipped with an elastic strap. One end of the elastic strap is covered by the edge-binding tape on the first package 11b and stitched to the first package, while the other end of the elastic strap extends to the outer surface of the storage pocket. A hook side of Velcro is stitched on the elastic strap extending into one end of the storage pocket, allowing the elastic strap to be adhered directly to the storage pocket. This way, when a tablet is placed inside the storage pocket, the elastic strap partially seals the opening, effectively preventing the tablet from slipping out.

As shown in FIG. 11, a diagonal support plate 100b made of the rigid third layer group is stitched on the side of the second package 12b opposite to the connecting section 14b. The diagonal support plate 100b is capable of rotating relative to the second package 12b. On both sides of the diagonal support plate 100b, a left support plate 21b and a right support plate 22b, both made of the third layer group, are rotatably installed.

The third layer group consists, from outer to inner, of a fabric layer, a rigid plastic plate, and a flannelette layer. The edges of these layers are covered with edge-binding tapes and stitched together. The structure of the third layer group matches that in Embodiment 1, and thus its specifics are not reiterated here.

As illustrated in FIG. 12, a main connecting plate 101b is attached to the bottom of the diagonal support plate 100b. The main connecting plate 101b features a protrusion 102b. By connecting the main connecting plate 101b to the first package 11b, the diagonal support plate 100b can be tilted and secured to the first package 11b to support the tablet. The protrusion 102b acts as a barrier to prevent the tablet from slipping.

The main connecting plate 101b is formed by stitching a fabric layer and the hook side of Velcro, with a raised sponge strip placed between the fabric layer and the hook side of Velcro to create the protrusion 102b.

The bottom edges of the left support plate 21b and the right support plate 22b are inclined. When the left support plate 21b and the right support plate 22 b are unfolded and stand upright on the first package 11 b through their front sides, gaps are formed between the rear sides of the left support plate 21b and the right support plate 22b and the first package 11b. This gaps allow heat emitted by the tablet to dissipate easily, preventing the tablet from overheating during prolonged use in high outdoor temperatures.

Both the left support plate 21b and the right support plate 22b have flexible first connecting sections 24b to enable folding relative to the diagonal support plate 100b. The first connecting section 24b is formed by outward extension of the fabric layer and flannelette layer that constitute the third layer group. With this setup, the left support plate 21b and the right support plate 22b can be stitched together with the diagonal support plate 100b during stitching of the support plate 100b.

As shown in FIGS. 9 and 12, the inner bottom sides of the left support plate 21b and the right support plate 22b are both equipped with flexible connecting plates 25b for connecting to the first package 11b. The connecting plates 25b are positioned near the front sections of the left support plate 21b and the right support plate 22b to avoid obstructing the gaps.

The connecting plate 25b is formed by stitching a fabric layer and a hook side of Velcro. One side of the connecting plate 25b is stitched to the right support plate 22b to enable folding.

As shown in FIG. 12, a top plate 27b made of a rigid third layer group is stitched on the side of the second package 12b opposite to the connecting section 14b. The structure of the top plate 27b is consistent with that in Embodiment 1, and thus its specific details are not repeated here.

The first package 11b and the second package 12b can be opened and closed through a zipper stitched on the side 13b.

As shown in FIG. 12, a mesh fabric is stitched inside the second package 12b to form a document pocket 34b with an opening. The document pocket 34b can be opened and closed using a zipper.

A handle 37b is provided on the outer side of the connecting section 14b.

In this solution, by connecting the main connecting plate 101b to the first package 11b, the diagonal support plate 100b can be arranged on the first package 11b inclinedly. The protrusion 102b is used to brace the tablet. When the tablet is used, it can be leaned against the diagonal support plate 100b. Due to the bracing effect of the protrusion 102b, the tablet is less likely to slip, freeing both hands for easier operation. The top plate 27b, which is capable of rotating relative to the second package 12b, adjusts its position relative to the left support plate 21b and right support plate 22b through the left wing plate and right wing plate. This allows adjustment of the height of the top plate 27b and the amount of light entering the display, accommodating users of different heights and adapting to various external lighting conditions.
