Description

Technical Field

[0001] The present invention relates to the technical field of inflatable mattresses, and more specifically, to an inflatable mattress integrally provided with a bed frame. Background Art

[0002] As a convenient bedroom furniture, inflatable beds are being gradually popularized. Common inflatable beds are divided into two categories. One is an inflatable bed composed of an inflatable mattress that does not require a bed frame and can be directly placed on the ground for inflation use. The other is an inflatable bed composed of a bed frame and an inflatable mattress that requires a bed frame and is placed on the bed frame for use after assembling the bed frame and inflating.

[0003] A Chinese patent with the publication number CN208318807U discloses an inflatable mattress, which includes an inflatable body and a bed cover covering the inflatable body. The bed cover includes a bed cover bottom, a bed cover surround, and a bed cover surface. The edge of the bed cover bottom is connected to the bottom edge of the bed cover surround, and the edge of the bed cover surface is connected to the top edge of the bed cover surround, thereby forming a cavity covering the inflatable body.

[0004] In the prior art, similar inflatable mattresses like the above need to assemble the inflatable body, the bed cover, and the foam layer by themselves before use, and then cooperate with a bed frame to raise the use position to facilitate getting on and off the bed. The bed frame used in conjunction with the inflatable mattress is generally a detachable and assembled wooden or steel structure. The weight of the bed frame is relatively heavier than that of the inflatable mattress, and the assembly operation of the bed frame takes a certain amount of time and is cumbersome, reducing the convenience of using the inflatable mattress. Summary of the Invention

[0005] Aiming at the existing technical problems, the purpose of the present invention is to provide an inflatable mattress integrally provided with a bed frame, which has the advantage of improving the convenience of using the inflatable mattress.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An inflatable mattress integrally provided with a bed frame includes a comfort layer, a support airbag disposed below the comfort layer, and a bed cover surrounding the outside of the comfort layer and the support airbag. The bottom surface of the bed cover away from the comfort layer is an open surface, and an adsorption concave portion is provided on the bottom surface of the support airbag away from the comfort layer.

[0008] By adopting the above technical solution, when assembling the inflatable mattress of the present invention, the opening of the bed cover is placed upward, the comfort layer is placed in the bed cover and fits the inner side of the bed surface, and then the support airbag is placed in the bed cover and is located on the surface of the comfort layer. After the support airbag is inflated and expanded to form, the bed cover is pulled so that the bed cover, the comfort layer and the support airbag fit closely to each other. After the inflatable mattress is inflated and formed, the inflatable mattress is turned over so that the opening of the bed cover faces downward. When a person lies on the inflatable mattress, the weight of the person is applied to the surface of the bed cover. The support airbag is affected by the weight of the person, and its adsorption concave part is deformed toward the placement surface, so that the air in the adsorption concave part is squeezed and discharged outward by the deformation. The inflatable mattress as a whole is stably adsorbed on the placement surface under the pressure difference at the bottom of the support airbag. The support airbags cooperate with the comfort layer to provide comfortable support to the human body. At the same time, they cooperate with the opening surface at the bottom of the mattress cover to increase the height and stabilize the support, thereby acting as a bed frame, making it convenient for users to get on and off the bed, etc., thereby reducing the need to assemble the bed frame and various mattress cover surfaces when using a traditional inflatable bed, thereby improving the convenience of using the inflatable mattress.

[0009] The present invention is further configured as follows: the support airbag includes an upper piece, a lower piece and a side panel, a plurality of limiting draw straps are connected between the relative inner surfaces of the upper piece and the lower piece, and upper diagonal draw straps and lower diagonal draw straps are respectively connected between the upper piece and the side panel and between the lower piece and the side panel.

[0010] By adopting the above technical solution, the limiting drawstring cooperates with the upper diagonal drawstring and the lower diagonal drawstring to limit the support airbag, so that the fitting surface between the support airbag and the comfort layer and the isolation layer is kept as flat as possible, thereby improving the stability of the overall structure of the mattress and the comfort of the mattress surface.

[0011] The present invention is further configured as follows: a plurality of support airbags are arranged horizontally at intervals below the comfort layer, and an isolation layer is filled between adjacent support airbags.

[0012] By adopting the above technical solution, the arrangement of a plurality of supporting airbags in conjunction with the isolation layer facilitates the separation of the respective use environments when the number of people using the mattress is more than one person. When assembling the inflatable mattress, after the comfort layer is placed in the mattress cover, the isolation layer is first placed in the mattress cover, and the supporting airbags are placed on both sides of the isolation layer. When the supporting airbags are inflated and expanded to form, the isolation layer is clamped between adjacent supporting airbags to separate the adjacent supporting airbags and reduce the influence of adjacent airbags on each other.

[0013] The present invention is further configured as follows: a limiting strip is provided on the opening surface of the bedspread below the isolation layer, the length direction of the limiting strip is parallel to the length direction of the isolation layer, and both ends of the limiting strip are integrally connected to a pair of side edges of the opening surface of the bedspread.

[0014] By adopting the above technical solution, the limiting stay is used to limit the isolation layer between adjacent support air bags, reducing the possible displacement of the isolation layer during the use of the mattress, and cooperating with the side wall of the support air bag and the comfort layer to improve the stability of the position of the isolation layer. At the same time, the arrangement of the limiting stay at the opening surface of the bed cover also improves the overall limiting and shaping effect of the opposite side walls of the bed cover connecting the two ends of the limiting stay on its internal components.

[0015] The present invention is further configured that: a protective strip is respectively connected to the long side of the limiting stay, and an adhesive layer capable of making the protective strip fit on the surface of the isolation layer is coated on the inner side surface of the protective strip facing the comfort layer, and a release protective paper is also attached to the outer surface layer of the adhesive layer.

[0016] By adopting the above technical solution, during the assembly of the mattress, the protective strips on both sides of the limiting stay are attached to the surface of the isolation layer through the adhesive layer, improving the structural stability between the limiting stay and the isolation layer, and at the same time, it is also convenient to initially determine the position of the isolation layer and place the uninflated support air bags on both sides of the isolation layer for inflation. The release protective paper attached to the adhesive layer is used to ensure the adhesiveness of the adhesive layer, preventing it from contacting other components during the transportation of the inflatable mattress before the assembly and inflation operations, which may reduce the adhesiveness of the adhesive layer.

[0017] The present invention is further configured that: the length of the limiting stay is less than the distance between a pair of side edges of the opening surface of the bed cover where it is located.

[0018] By adopting the above technical solution, the length of the limiting stay is less than the distance between the side edges of a pair of bed covers it connects, so that when the support air bag is fully inflated, the limiting tension of the limiting stay on the side of the opening surface of the bed cover it connects is increased, further improving the limiting effect of the bed cover on the internal components and enhancing the overall shaping effect of the inflatable mattress.

[0019] The present invention is further configured that: an elastic hip wrapping edge is also connected to the peripheral edge along the opening surface of the bed cover.

[0020] By adopting the above technical solution, through the setting of the elastic hip wrapping edge on the opening surface of the bed cover, the stability of the combined structure of the bed cover and the support air bag is improved, reducing the possible displacement of the bed cover during the use of the inflatable bed due to the sleeping movements of the user.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) Through the setting that the bottom surface of the bed cover is the opening surface and the adsorption concave part on the support air bag, the step of assembling the bed frame is omitted, improving the use convenience and at the same time, also improving the stability of the position of the mattress on the placement surface;

[0023] (2)By setting the upper limit pull strip on the opening surface of the bedspread, the position stability of the internal components of the bedspread and the overall shaping effect of the mattress are improved;

[0024] (3)By setting the protective strips and adhesive layers on both sides of the limit pull strip, the positioning effect of the limit pull strip on the isolation layer is improved, facilitating the placement and inflation of the support airbag. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0034] The present invention will be described in detail below with reference to the drawings and embodiments.

[0035] Embodiment 1

[0036] The present invention discloses an inflatable mattress integrally provided with a bed frame, such as Figure 1 , 2As shown, it includes a comfort layer 1, a support airbag 2 placed below the comfort layer 1, and a bed cover 4 surrounding the outside of the comfort layer 1 and the support airbag 2. The bottom surface of the bed cover 4 away from the comfort layer 1 is an open surface. An adsorption concave part 5 is arranged on the bottom surface of the support airbag 2 away from the comfort layer 1. When using the inflatable mattress of the present invention, the support airbag 2 is located at the open surface at the bottom of the bed cover 4 and fits and adsorbs on the placement surface to replace the traditional assembled bed frame.

[0037] As Figure 1 , 2 shown, in this embodiment, the number of the support airbags 2 is one. The support airbag 2 includes an upper sheet 21, a lower sheet 22 and a side surround 23. The material of the support airbag 2 is TPU and is integrally welded and is in a cube shape. A plurality of limiting straps 24 are connected between the relative inner layers of the upper sheet 21 and the lower sheet 22. The limiting straps 24 in this embodiment are wire straps, and the plurality of limiting straps 24 are arranged at equal intervals along the length direction of the upper sheet 21 and the lower sheet 22. Upper diagonal straps 25 and lower diagonal straps 26 are respectively connected between the upper sheet 21 and the side surround 23 and between the lower sheet 22 and the side surround 23. The upper diagonal straps 25 and the lower diagonal straps 26 are arranged around the periphery of the side surround 23. In this embodiment, both the upper diagonal straps 25 and the lower diagonal straps 26 are sheet straps. The number of the upper diagonal straps 25 and the lower diagonal straps 26 is four each. The four upper diagonal straps 25 are respectively connected to the four upper side wall surfaces of the side surround 23 and the inner surfaces near the four side edges of the upper sheet 21. The four lower diagonal straps 26 are respectively connected to the four lower side wall surfaces of the side surround 23 and the inner surfaces near the four side edges of the lower sheet 22. The adsorption concave part 5 is formed by the cooperation of the lower diagonal straps 26, the lower sheet 22 and the side surround 23. The inflation method of the support airbag 2 in this embodiment is the same as that of the airbag of the common inflatable mattress on the market. For example, for an inflatable mattress disclosed in a Chinese patent with a publication number of CN205459508U, it is inflated by connecting an external inflatable tube to an air pump; or for an adjustable inflatable mattress disclosed in a Chinese patent with a publication number of CN202653667U, it is inflated by setting an air pump on the inflatable body.

[0038] As Figure 2 , 3 shown, the comfort layer 1 is in a thick sheet shape, and the area of the comfort layer 1 is the same as the area of the top surface of the bed cover 4. In this embodiment, the material of the comfort layer 1 is PU memory foam. Combining Figure 4 , the internal space of the bed cover 4 is in a cube shape after being unfolded, and the height of the bed cover 4 after being unfolded is the same as the sum of the heights of the support airbag 2 and the comfort layer 1. A hip wrapping edge 6 is also sewn on the peripheral edge of the bed cover 4 at the open surface. The hip wrapping edge 6 is made of a material with a certain elasticity. In this embodiment, the hip wrapping edge 6 is selected as an elastic binding strip.

[0039] When using the inflatable mattress of the present invention, when a person lies on the bed surface, the adsorption concave part 5 formed on the bottom surface of the support airbag 2 deforms, and under the action of air pressure, it adsorbs on the placement surface, maintaining the stability of the inflatable mattress during use. The support airbag 2 cooperates with the comfort layer 1 to provide comfortable support for the human body. At the same time, it cooperates with the opening surface at the bottom of the bed cover 4 to play a role in heightening and stable support, facilitating the user's actions such as getting in and out of bed, thus playing the role of a bed frame. The inflatable mattress of the present invention reduces the assembly steps of the upper and lower bed covers 4 and the bed frame of the traditional inflatable mattress while ensuring the stability of the mattress, thereby improving the convenience of using the inflatable mattress.

[0040] Embodiment 2

[0041] The present invention discloses an inflatable mattress integrally provided with a bed frame. As Figure 5 , 6 shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the number of support airbags 2 is two, and the two support airbags 2 are arranged at intervals below the comfort layer 1. An isolation layer 3 is filled between the adjacent support airbags 2 below the comfort layer 1. The isolation layer 3 is in the shape of a thick sheet, its length is the same as the length of the support airbag 2, and its width is equal to the height of the support airbag 2 when it is filled with gas. When the support airbag 2 is filled with gas, the isolation layer 3 is clamped between the two support airbags 2, and one end surface thereof is attached to the comfort layer 1.

[0042] As Figure 6 , 7 shown, the bed cover 4 is unfolded into a cube shape with an open bottom surface. A limit drawbar 41 is further provided below the isolation layer 3 on the opening surface of the bed cover 4. The length direction of the limit drawbar 41 is parallel to the length direction of the isolation layer 3. The two end sides of the limit drawbar 41 in the length direction are integrally connected to the short side edges of the opening surface of the bed cover 4, and the connection position of the limit drawbar 41 and the opening surface of the bed cover 4 is the middle of the side edge of the opening surface where it is located. At the same time, the length of the limit drawbar 41 is less than the width of a pair of side edges of the opening surface where it is located when the support airbag 2 is filled with gas. The width of the limit drawbar 41 is the same as the thickness of the isolation layer 3, and a protective strip 42 is integrally connected to the long side of each of the long sides of the limit drawbar 41. There is a bending indentation on the connecting side of the protective strip 42 and the limit drawbar 41. The protective strip 42 is in the shape of a long sheet, and its length is the same as the length of the limit drawbar 41. Combining Figure 8 , an adhesive layer 43 is coated on the inner long side of the protective strip 42 facing the isolation layer 3 (that is, the inner side of the comfort layer 1), and a release protective paper 44 is attached to the outer surface of the adhesive layer 43. When assembling the inflatable mattress of the present invention, the release protective paper 44 is torn off, and the protective strip 42 is attached to the side surface of the surface of the isolation layer 3 through the adhesive layer 43 to preliminarily position the isolation layer 3, facilitating the placement of the un-inflated support airbags 2 on both sides of the isolation layer 3.

[0043] When assembling the inflatable mattress of the present invention, first turn the bed cover 4 so that its opening face faces upward, and then lay the comfort layer 1 flat through the opening face on the inner side of the bed surface of the bed cover 4. Place the isolation layer 3 into the bed cover 4 and attach the protective strip 42 of the limit draw bar 41 to the long side side wall of the isolation layer 3 adjacent to the opening face to preliminarily position the isolation layer 3. Then, place the bottom surfaces of the two support air bags 2 upward on both sides of the isolation layer 3 in the bed cover 4 respectively and perform the inflation operation. After the support air bags 2 are filled with air, the isolation layer 3 and the comfort layer 1 are tightly attached to the inside of the bed cover 4 under the extrusion of the support air bags 2. Finally, turn the inflatable mattress so that the opening face faces the placement surface, and the assembly is completed. When using the inflatable mattress of the present invention, when a person lies on the bed surface, the adsorption concave part 5 formed on the bottom surface of the support air bag 2 deforms and adsorbs on the placement surface under the action of air pressure, maintaining the stability of the mattress during use. The support air bag 2 cooperates with the comfort layer 1 to provide a comfortable support for the human body, and at the same time, it cooperates with the opening face at the bottom of the bed cover 4 to play a role in heightening and stable support, facilitating the use actions such as getting on and off the bed by the user. The inflatable mattress of the present invention reduces the assembly steps of the upper and lower bed covers 4 and the bed frame of the traditional inflatable mattress while ensuring the stability of the mattress, thereby improving the convenience of using the inflatable mattress.

[0044] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
