Description

Technical Field

[0001] This application relates to the field of furniture storage technology, and in particular to a type of furniture including a seat cushion, a back cushion, and a waterproof and dustproof bag. Background Technology

[0002] With the rapid growth in demand for outdoor leisure, self-driving camping, and children's activities, foldable, washable, and portable seat / back cushions have become a market hotspot. Current technology generally uses separate seat and back cushions covered by a single fabric cover. While this allows both to be slipped on simultaneously, the cover openings often use ordinary one-way zippers or buttons, leaving the zipper pull exposed, making it easy for rainwater and drinks to seep in. Furthermore, the zipper travel is short, requiring significant squeezing of the foam during assembly and disassembly, which is inconvenient.

[0003] To overcome the shortcomings of existing technologies, this application proposes a waterproof and dustproof bag that has a simple structure, reliable waterproofing, and can be quickly stored. Utility Model Content

[0004] The purpose of this application is to provide a waterproof and dustproof bag and furniture, which is fixedly connected to the furniture to be covered through a variety of detachable structures, and a sealing structure is set on the adjacent edges of different extended wings, so as to achieve quick storage and waterproof and dustproof effect while further improving the waterproof and dustproof effect.

[0005] The first aspect of this application provides a waterproof and dustproof bag for covering the seat and back cushions of furniture to provide a waterproof and dustproof effect. The waterproof and dustproof bag includes a main body and a first extension wing and a second extension wing extending outward from the main body. The two first extension wings are disposed opposite to each other on both sides of the main body along a first direction, and the two second extension wings are disposed opposite to each other on both sides of the main body along a second direction, wherein the first direction is perpendicular to the second direction.

[0006] The first extended wing has a first connecting structure at its end furthest from the main body, and the second extended wing has a second connecting structure at its end furthest from the main body. The waterproof and dustproof bag is fixedly connected to the four sides of the furniture through the first connecting structure and / or the second connecting structure with different detachable connection methods. The first connecting structure is located at the edge of the first extended wing, and the second connecting structure is spaced apart from the edge of the second extended wing.

[0007] The first and second extended wings are equipped with zipper structures along their adjacent edges to seal the gap between them after the waterproof and dustproof bag is fixedly connected to the furniture.

[0008] Furthermore, the first connecting structure is a zipper, and the second connecting structure is Velcro.

[0009] Furthermore, a third connecting structure is provided on the side of the second extended wing that is away from the second connecting structure. The third connecting structure is configured to cooperate with the second connecting structure of the other second extended wing to facilitate the storage of the waterproof and dustproof bag. The third connecting structure is located in the middle of the second extended wing, and both the third connecting structure and the second connecting structure are Velcro.

[0010] Furthermore, the end surface of the first extended wing is provided with a handle to facilitate the movement of the waterproof and dustproof bag and the seat and back cushions of the furniture when the waterproof and dustproof bag is covering the outside of the furniture seat and back cushions.

[0011] Furthermore, the waterproof and dustproof bag further includes an inward folding structure, which is disposed on the first extended wing and is used to conceal the first connecting structure to improve the waterproof effect.

[0012] Furthermore, the length and width of the first extended wing are equal to the length and width of the second extended wing.

[0013] The second aspect of this application provides a piece of furniture for use with the waterproof and dustproof bag as described above. The furniture includes a seat cushion and a back cushion, which are detachably connected. When the back cushion is stacked on top of the seat cushion, the waterproof and dustproof bag adheres to the bottom of the back cushion and the side wall of the seat cushion, and covers the outside of the seat cushion and the back cushion to provide a waterproof and dustproof effect.

[0014] The bottom of the seat cushion is provided with a fourth connecting structure and a fifth connecting structure, which are arranged adjacent to each other. The first connecting structure of the waterproof and dustproof bag is arranged in conjunction with the fourth connecting structure and / or the second connecting structure of the waterproof and dustproof bag is arranged in conjunction with the fifth connecting structure, so as to complete the fixed connection with the bottom of the seat cushion.

[0015] Furthermore, the fourth connecting structure is a zipper, and there are two fourth connecting structures, which are respectively located at the front and rear ends of the bottom of the seat cushion along the length direction.

[0016] Furthermore, the fifth connecting structure is a Velcro closure, and there are two fifth connecting structures, which are respectively located at the left and right ends of the bottom of the seat cushion along the length direction.

[0017] Furthermore, the furniture further includes a lip structure located at the bottom of the cushion, the lip structure being used to cover the fourth connection structure to improve waterproofing.

[0018] Unlike existing technologies, the waterproof and dustproof bag of this application consists of a main structure, first extended wings, and second extended wings. Two first extended wings are positioned opposite each other on both sides of the main body along a first direction, and two second extended wings are positioned opposite each other on both sides of the main body along a second direction, with the first direction perpendicular to the second direction. A first connecting structure is provided at the end of each first extended wing furthest from the main body, and a second connecting structure is provided at the end of each second extended wing furthest from the main body. This allows the waterproof and dustproof bag to be securely connected to the furniture to be covered via the first and second extended wings, thus providing a comprehensive waterproof and dustproof effect by tightly covering the seat and back cushions of the furniture. Simultaneously, zipper structures are provided along the adjacent edges of the first and second extended wings to seal the gaps between them, further enhancing the waterproof and dustproof effect.

[0019] In addition, the waterproof and dustproof bag of this application achieves a fixed connection with furniture through a detachable first connection structure and a second connection structure, which enables quick waterproof and dustproof storage of furniture cushions and back pads, or quick disassembly to complete the storage of the waterproof and dustproof bag itself.

(Example:) Figure 4 As shown, the furniture 40 of this application includes a seat cushion 20 and a back cushion 30, which are detachably connected. Figure 6 and Figure 7 As shown, when the back cushion 30 is stacked on top of the seat cushion 20, the waterproof and dustproof cover 10 adheres to the bottom of the back cushion 30 and the side wall of the seat cushion 20, and covers the outside of the seat cushion 20 and the back cushion 30 to provide a waterproof and dustproof effect.

[0053] Please refer to further information. Figures 8-10 , Figure 8 yes Figure 4 First structural diagram of the middle seat cushion. Figure 9yes Figure 4 Schematic diagram of the second structure of the middle seat cushion. Figure 10 yes Figure 4 A structural diagram of the center cushion. (See diagram below.) Figure 8 and Figure 9 As shown, the bottom of the seat cushion 20 in this embodiment is provided with a fourth connecting structure 21 and a fifth connecting structure 22, and the fourth connecting structure 21 and the fifth connecting structure 22 are arranged adjacent to each other. The first connecting structure 14 of the waterproof and dustproof bag 10 is arranged in cooperation with the fourth connecting structure 21 and / or the second connecting structure 15 of the waterproof and dustproof bag 10 is arranged in cooperation with the fifth connecting structure 22, so as to complete the fixed connection with the bottom perimeter of the seat cushion 20.

[0054] Specifically, in this embodiment, the fourth connecting structure 21 is a zipper, and there are two fourth connecting structures 21, which are respectively located at the front and rear ends of the bottom of the seat cushion 20 along the length direction. The fifth connecting structure 22 is a Velcro, and there are two fifth connecting structures 22, which are respectively located at the left and right ends of the bottom of the seat cushion 20 along the length direction.

[0055] Optionally, in this embodiment, the seat cushion 20 is filled with sponge, and the top surface has a silk floss layer. The dimensions of the seat cushion 20 are approximately 600mm wide, 700mm long, and 180mm thick. The front radius (front R) of the upper part of the seat cushion 20 is 50mm, and the rear radius (rear R) is 80mm. The back cushion 30 is filled with doll cotton, weighs approximately 1.4kg, and has dimensions of approximately 600mm wide, 550mm long, and 80mm thick.

[0056] like Figure 7 As shown, the furniture 40 in this embodiment further includes a lip structure 23 disposed at the bottom of the cushion 20. The lip structure 23 is used to cover the fourth connecting structure 21 to improve the waterproof effect.

[0057] like Figure 4 As shown, when the seat cushion 20 and back cushion 30 are needed, the fixed connection between the detachable waterproof and dustproof bag 10 and the bottom of the seat cushion 20 is removed, leaving only one end of the fixed connection between the waterproof and dustproof bag 10 and the bottom of the seat cushion 20, which facilitates quick positioning during storage. Meanwhile, the back cushion 30 is placed vertically on the seat cushion 20, and the remaining part of the waterproof and dustproof bag 10 can be rolled up and placed on the back of the back cushion 30, thus completing the storage of the waterproof and dustproof bag 10 without affecting its aesthetics during use.

[0058] When it is necessary to waterproof and dustproof the furniture (40), you can follow the instructions. Figures 5(a)-5(e) The operation shown completes the storage. Figures 5(a)-5(e) This is a diagram illustrating the process of tidying up the furniture in this application.

[0059] Specifically, when it is necessary to attach the waterproof and dustproof bag 10 to the outside of the furniture 40 to achieve waterproof and dustproof storage, the back cushion 30, which is placed vertically on the seat cushion 20, is laid flat in the rotation direction shown in Figure 5(a) so that it is stacked on the seat cushion 20.

[0060] After the back cushion 30 and the seat cushion are stacked, the rolled-up waterproof and dustproof bag 10 is opened in the rotation direction shown in Figure 5(b), and the second extension wing 13 stacked on the inside of the main body 11 is unfolded in the rotation direction shown in Figure 5(c).

[0061] When the waterproof and dustproof bag 10 is fully unfolded, the main body 11 of the waterproof and dustproof bag 10 is attached to the bottom of the back pad 30, the first extension wing 12 is attached to the front and rear ends of the seat pad 20 in the width direction, and the second extension wing 13 is attached to the side wall of the back pad 30 and the left and right ends of the seat pad 20 in the width direction. Then, the zipper structure 18 is closed in the direction shown in Figure 5(d) to roughly fix the structural shape of the waterproof and dustproof bag 10.

[0062] After roughly fixing the structural shape of the waterproof and dustproof bag 10, the furniture 40 and the waterproof and dustproof bag 10 can be lifted, and the first connecting structure 14 can be connected to the fourth connecting structure 21, and the second connecting structure 15 can be connected to the fifth connecting structure 22, so as to achieve the fixed connection between the waterproof and dustproof bag 10 and the bottom of the cushion 20, and complete the waterproof and dustproof storage of the furniture 40 as shown in Figure 5(e).

[0063] like Figure 6 As shown, when the back cushion 30 is stacked on the seat cushion 20 in this embodiment, its length gradually decreases. This application can design the size of the waterproof and dustproof bag 10 so that when the waterproof and dustproof bag 10 is fitted onto the seat cushion 20 and the back cushion 30, it fits perfectly against the bottom of the back cushion 30 and the four sides of the seat cushion 20, achieving compact storage while saving the material of the waterproof and dustproof bag 10.

[0064] Optionally, in this embodiment, the width of the first extension wing 12 is approximately equal to the length of the seat cushion 20 and the back cushion 30. When the waterproof and dustproof cover 10 covers the outside of the seat cushion 20 and the back cushion 30, the main body 11 is attached to the bottom of the back cushion 30, the first extension wing 12 is attached to the side of the back cushion 30 and the front and rear sides of the seat cushion 20, and the second extension wing 13 is attached to the side of the back cushion 20 and the left rear sides of the seat cushion 20.

[0065] The waterproof and dustproof bag 10 of this application combines different detachable connection methods, including zippers and Velcro, to achieve a fixed connection with the bottom of the seat cushion 20, thereby improving the connection stability. The waterproof and dustproof bag 10 is designed to cover both the seat cushion 20 and the back cushion 30 while saving materials. At the same time, the waterproof and dustproof bag 10 is set to fit the bottom of the back cushion 30 and the four sides of the seat cushion 20, achieving a tight overall storage and reducing air bubbles and wrinkles at the corners of the seat cushion 20 and the back cushion 30, which does not affect the aesthetics and improves the waterproof coverage effect. The waterproof and dustproof bag 10 has a zipper structure 18 set on the adjacent edges of the two adjacent extended wings, which further improves the waterproof and dustproof effect while achieving quick storage and waterproof and dustproof protection.

[0066] In summary, the waterproof and dustproof bag 10 of this application has a simple structure, reliable waterproofing, quick storage and easy carrying, and has multiple advantages such as waterproofing, breathability, easy disassembly and assembly, compact storage and neat appearance.

[0067] The above are merely embodiments of this application and do not limit the patent scope of this application.
