MATTRESS STRUCTURE WITH HIGH FLATNESS

Description

TECHNICAL FIELD

The present disclosure relates to the technical field of mattress structures, in particular to a mattress structure with high flatness.

BACKGROUND OF THE INVENTION

Mattresses are a necessity in some people's lives, and the comfort level thereof may directly affect the quality of life, further affecting physical health. With increasing rise of living standards, the desire for the comfort of mattresses is becoming more and more strong; however, the existing mattresses made of steel wire spring pads have gradually failed to meet people's requirements for sleep comfort due to their single rigid or soft structure. Accordingly, inflatable mattresses based on airbags came into being. At present, a common inflatable mattress mainly uses an air pump to circulate the inflation and deflation of each airbag inside the pad through main and auxiliary air channels, so that the height of the mattress surface can adapt to different sleeping positions, thereby improving the comfort of the mattress. However, in the existing mattress structure, due to the fact that the main air channel is mostly provided on the side wall of the main part of a mattress core and located between the surrounding edge and the core of the mattress, its positioning is poor, leading to being prone to be pulled, twisted and displaced during the process of inflation and deflation, affecting the fluency of inflation and deflation. Most importantly, the height of the surrounding edge of the existing mattress structure is unadjustable, that is, the height of the surrounding edges cannot change with the height of the mattress surface; accordingly, there will be a certain height difference between the surrounding edge and the surface of the mattress during adjusting the height of the mattress surface, which seriously influences user experience. In view of this, it is particularly important to develop a mattress structure with high flatness to achieve a highly coordinated effect between the edges and the mattress surface.

SUMMARY OF THE INVENTION

Further, the mattress body may further comprise a lining, the lining may comprise a plurality of first accommodating grooves for placing the air bag components, and the air bag components located in each first accommodating groove may be communicated with the main air channel via an auxiliary air channel, respectively.

Further, the lining may be further provided with a plurality of second accommodating grooves on a side corresponding to an upper surface of the mattress body. The second accommodating grooves may be provided with an elastic filler inside for increasing softness of the upper surface of the mattress body.

Further, the elastic filler may be a U-shaped structure with a direction of an opening thereof being arranged on a side corresponding to the main air channel, and positions where two outer side walls and a bottom of the U-shaped structure are connected may be provided with an inclined surface respectively for reducing deformation of the mattress body in the height direction.

Further, the lining may be provided with a plurality of sound-absorbing holes distributed uniformly.

DETAILED DESCRIPTION

The following is a detailed explanation of the preferred embodiments of the present disclosure so that the advantages and characteristics thereof can be more easily understood by those skilled in the art; thereby making a clearer definition of the protection scope of the present disclosure.

As shown in FIGS. 1-8, a mattress structure with high flatness is provided in an embodiment of the present disclosure. For details, please refer to FIG. 1, which schematically shows an explode diagram of the mattress structure in the embodiment. The mattress structure may include a mattress body 1 and a surrounding edge 2 continuously arranged around the mattress body 1; that is, the surrounding edge 2 forms a rectangle or square shaped structure for placing the mattress body 1. The surrounding edge 2 may be the same height as the mattress body 1. It shall be understood that in some embodiments, if there is no need to provide the surrounding edge around all the four sides of the mattress body, the unnecessary surrounding edge can be omitted according to actual needs.

A plurality of air bag components 11 may be provided by row inside the mattress body 1 and laid in a single layer or a double layer. A main air channel 3 for communicating with each of the air bag components 11 may be provided at the bottom of the surrounding edge 2. The main air channel 3 may be arranged at the bottom or inside of the surrounding edge along the periphery of the mattress body. The main air channel 3 may jack up the surrounding edge 2 when the air inflation mechanism is in an inflated state, and the surrounding edge 2 and the main air channel 3 may be arranged in a coordinated manner in positions, such that the regulation of the surrounding edge and the mattress body can be achieved in a height direction in a linked manner. When the air bag components in the mattress body 1 are inflated by means of the main air channel 3, the entire mattress body 1 may be deformed, which is mainly shown in the increase in height. The surrounding edge 2, due to its role being to surround and protect the mattress body 1, plays a role in improving the stability by its structure; therefore, the surrounding edge 2 is usually configured as a micro deformation structure with less deformation than the mattress body 1. Through the design of the above structure, the main air channel 3 can cleverly compensate for the problem of insufficient deformation of the surrounding edge 2.

That is, when the height of the main air channel 3 increases, the main air channel 3 may jack up the surrounding edge 2 above it; and when the height of the main air channel 3 decreases, the height of the surrounding edge 2 may decrease with the height of the main air channel 3. The linkage between the surrounding edge 2 and the main air channel 3 in height is beneficial to eliminate the height difference between the surfaces of the surrounding edge 2 and the mattress body 1 in the process of inflation and deflation, avoiding bulging on the surface of the mattress body 1, and thereby improving the surface flatness of the mattress structure.

The main air channel may be provided with a fracture formation to achieve air flow introduction. The two ends of the fracture formation may be connected with a pump body 4 via electromagnetic valves. The pump body 4 for supplement gas to each of the air bag components 11 through the main air channel 3 may be fixedly mounted at the bottom of the mattress body 1. Of course, the gas inside the air bag component 11 may also be discharged outward through the main air channel 3, which may be implemented by a structure similar to the inflation and deflation structure of the air bag component 11 in prior art without going into details here.

In some embodiments, the selection of materials for the surrounding edge 2 may be various. For example, it may be a sponge surrounding edge, a spring surrounding edge, an air bag type surrounding plate, and one or more combinations thereof. FIG. 2 schematically shows an example of the surrounding edge 2 formed by an elastic body 21 in an exploded manner. Specifically, the elastic body 21 of the surrounding edge 2 may be in a long strip-shaped sponge arrangement, which can be selected for its softness and hardness according to the comfort requirements of different mattresses.

In other embodiments, the structure of the surrounding edge 2 may also be designed as that shown in FIG. 3, specifically, the surrounding edge 2 may include an edge air bag group 22 and an edge lining 23 to realize the adjustment of the softness and hardness of the surrounding edge 2. The edge lining 23 may be a long tubular hollow formation composed of an elastic structure, with a long strip-shaped edge air bag group 22 arranged therein by column. In order to further adjust the softness and hardness of the surrounding edge 2, there is at least one layer of the edge air bag group 22 in the height of the surrounding edge 2. In a preferred embodiment, the edge lining 23 can be made of silicone or leather material.

As a preferred embodiment, the surrounding edge 2 may also be provided with a limiting formation 5 to further eliminate a gap between the mattress body 1 and the surrounding edge 2 arranged around the mattress body 1. FIGS. 4 and 5 schematically illustrate the relationship among the limiting formation 5, the surrounding edge 2 and the mattress body 1. As shown in FIGS. 4 and 5, the limiting formation 5 is continuously arranged on the outside of the surrounding edge 2 and connected with mattress body 1 limit the surrounding edge 2. The limiting formation here may refer to a limiting holder made of elastic material, or a wrapping layer made of soft materials such as leather, which is not limited here. Taking the wrapping layer made of leather as an example, the upper and lower edges of the wrapping layer may be connected with the mattress body 1 by bonding, riveting, thread sewing, zipper, or hook & loop fastener, etc., so as to limit and fix the surrounding edge 2, and thus completely eliminate the gap between the mattress body 1 and the surrounding edge 2. The main air channel 3 may be arranged at the bottom of the surrounding edge 2 and fixedly connected to the limiting formation 5 to realize the linkage with the surrounding edge 2. In other words, the main air channel 3 may be arranged between the surrounding edge 2 and the limiting formation 5, and is fixedly connected arranged on the inner surface of the limiting formation 5. Of course, the mode of connection between the main air channel 3 and the limiting formation 5 may include but be not limited to bonding, riveting, welding or sewing.

In some embodiments, the limiting formation 5 may include a limiting piece 51 arranged continuously along the surrounding edge 2. The limiting piece 51 may be arranged on the opposite side of the surrounding edge 2 from the mattress body 1; that is, the limiting piece 51 may be continuously arranged along the outer wall of the surrounding edge 2. The bottom edge of the limiting piece 51 may be connected with the mattress body 1 via the connecting part 52. The main air channel 3 may be fixedly arranged with the connecting part 52; that is, the main air channel 3 may be fixedly arranged on the inner surface of the connecting part 52, forming a combined structure of the two. In this embodiment, the connecting part 52 may be a zipper structure with two sides fixedly connected with the limiting piece 51 and the mattress body 1, respectively, for convenient disassembly.

Of course, the top edge of the limiting piece 51 may also be connected in a spliced manner with the mattress body 1 via another connecting part 52, which will not be limited here. In the present disclosure, the limiting formation 5 formed by the limiting piece 51 and the connecting part 52 may be regarded as a “U” type structure matched with the surrounding edge 2, and the two sides of the “U” type structure may be connected with the mattress body 1, forming a strip-type groove for receiving the surrounding edge 2. The surrounding edge 2 may be inserted into the strip-type groove to realize position limitation. In the embodiment, the limiting piece 51 and the connecting part 52 may be made of soft materials (such as leather) or elastic materials, and the two may be spliced or formed into one, such as welding or sewing, which is not limited specifically here.

As a preferred embodiment, the limiting formation 5 may be provided with a plurality of hollow formation as shown in FIG. 4, including but not limited to a strip-type hollow formation, a circular hollow formation, a polygonal hollow formation or an irregular hollow formation. Of course, a strip-type gap formed between adjacent connecting components mentioned above may also be a kind of hollow formation. The arrangement of the hollow formation here is mainly to eliminate noise generated by friction caused by pulling the limiting formation 5 in the process of the inflation and deflation. For example, the limiting formation 5 made of leather may be pulled due to the increase in volume during inflation, leading to noise. The arrangement of the hollow formation provides a certain deformation space for the limiting formation 5, which can effectively overcome the noise caused the leather pulling during inflation.

In terms of the mattress body 1, please refer to FIGS. 6-8. FIG. 5 schematically shows the internal structure of the mattress body 1. The mattress body 1 may include a lining 13 arranged on the inner side of the surrounding edge 2. The lining 13 may be made of spliced soft materials such as leather or elastic rubber, or it may be made of soft materials by an all-in-one way. Specifically, please refer to FIG. 7, the lining 13 may include a plurality of first accommodating grooves 131 for placing the air bag components 11. The first accommodating groove 131 here may serve as the space for fitting the air bags which may be placed in the first accommodating grooves 131, respectively. The air bags in each first accommodating groove 131 may be communicated with the main air channel 3 through the auxiliary air channel 31, respectively. In the embodiment, the first accommodating grooves 131 are designed as square accommodating grooves, each of which inside may accommodate at least an air bag that can be communicated with the main air channel 3 through the auxiliary air channel 31. The auxiliary air channel 31 may be attached to the side wall of the mattress body 1; that is, one end of the auxiliary air channel 31 may be connected to the air bag, and the other end may be communicated to the main air channel 3 through the gap between the outer wall of the mattress body 1 and the inner wall of the surrounding edge 2.

As a preferred embodiment, the lining 13 may be provided with a limiting groove arranged at a position thereof corresponding to each auxiliary air channel 31 to position and fix the auxiliary air channel 31. The limiting groove may be configured for the auxiliary air channel 31 to pass through. That is, the auxiliary air channel 31 may pass through the limiting groove to achieve fixed position between the auxiliary air channel 31 and the lining 13. Of course, in some embodiments, in order to further improve the position stability of the auxiliary air channel 31, a pressure bar may also be arranged on the limiting formation 5, so that the auxiliary air channel 31 can pass between the pressure bar and the limiting formation 5, thereby achieving secondary positioning of the auxiliary air channel 31. In addition, both ends of the pressure bar may be fixed with the inner surface of the connecting part 52, and the auxiliary air channel 31 may be passed between the pressure bar and the connecting part 52 to connect to the main air channel 3. It can be seen that the cooperation of the limiting groove and the pressure bar can effectively improve the position stability of the auxiliary air channel 31, avoiding the pulling and shifting of the auxiliary air channel 31 which affect the normal use of the mattress structure during the usage of the mattress.

In the present disclosure, the position limitation of the auxiliary air channel 31 is not limited to the above structure, for example, the auxiliary air channel 31 may be directly fixed on the limiting formation 5 or the inner wall of the surrounding edge 2 by bonding, riveting or welding, as long as the position limitation of the auxiliary air channel 31 can be achieved, and the present disclosure does not make the restriction for the position limitation.

Please refer to FIGS. 7 and 8, in order to improve the comfort of user sleep, a side of the lining 13 corresponding to the upper surface of the mattress body 1 may be provided with a plurality of second accommodating grooves 132 which are laid in a single layer on the mattress body 1. The second accommodating grooves 132 may be located on the top of the lining 13; that is, the second accommodating grooves 132 may be closest to the upper surface of the mattress body 1. The second accommodating grooves 132 may be provided inside with an elastic filler 12 for increasing the softness of the upper surface of the mattress body 1 to improve the comfort of user sleep. The elastic filler 12 mentioned here may be a strip-type sponge or latex.

As a preferred embodiment, the elastic filler 12 is a U-shaped structure, as shown in FIG. 9, with a direction of the opening of the U-shaped structure arranging on a side opposite to the main air channel; that is, the opening direction of the U-shaped structure is oriented on a side opposite to the upper surface of the mattress body 1. Moreover, the two lateral outer walls of the U-shaped structure are provided with an inclined surface respectively at a position where they each meet the bottom outer wall for reducing deformation and protrusion of the mattress body 1 in the height direction. Simply put, a groove is provided at the bottom of the elastic filler 12, and a inclined surface formation (which may also be regarded as a groove formation) is provided at the two sides of the elastic filler 12 near the upper surface respectively, so that the volume of the second accommodating grooves 132 is larger than that of the elastic filler 12, providing sufficient space for the deformation of the mattress body to reduce the deformation and protrusion of the mattress in the height direction after inflation, and further improving the flatness of the surface of the mattress body 1.

As a preferred embodiment, the lining 13 is provided with a plurality of sound-absorbing holes 133 distributed uniformly and arranged in an ordered array. The arrangement of the sound-absorbing holes 133 provide space for the deformation of the lining 13, and eliminate the noise caused by the pulling of the lining 13 during inflation. At the same time, the arrangement of the sound-absorbing holes 133 may also help to reduce the use of material and decrease the production cost of the lining. In the present disclosure, the sound-absorbing holes 133 may be polygonal hollow or irregular holes, such as square holes, circular holes, hexagonal holes, etc., which is not limited here. It shall be conceived by those skilled in the art that providing the sound-absorbing holes 133 of a single structure on the lining 13, or providing the sound-absorbing holes 133 of a plurality of structures on the lining 13, should be within the scope of protection of the present disclosure.

As a preferred embodiment, the outer side of each of the air bag components may be covered with a soft sound-absorbing layer, made of such as leather or rubber foam material film. The soft sound-absorbing layer may be attached onto the outer surface of the air bag by welding or adhesive, which can effectively absorb the noise caused by the air bag in the process of inflation or deflation, making the air bag achieve a silent effect without producing noise. Also, it can reduce the friction between the air bag and the lining 13 to avoid damage to the air bag, helping to prolong the service life of the air bag.

In other embodiments, the air bag component may also include an inflatable air bag component and a spring set arranged on the upper surface or lower surface of the inflatable air bag component. The inflatable air bag component may be in a double-layer manner, including a distribution layer and an upper layer. In order to reduce friction noise, the soft sound-absorbing layer may be arranged between the various components mentioned above, which may be, but not limited to, at least one of: the upper surface of the elastic filler, the lower surface of the elastic filler, the upper surface of the inflatable air bag component, the lower surface of the inflatable air bag component, the upper surface of the spring set, and the lower surface of the spring set.

The embodiments of the present disclosure provide a mattress structure with high flatness, which, by setting a continuous surrounding edge at the periphery of the mattress body and setting a main air channel at the bottom of the surrounding edge so as to make the surrounding edge link with the main air channel in the height direction, can ensure that the main air channel can drive the surrounding edge up or down during inflation or deflation to keep the surrounding edge and the surface of the mattress body are consistent in the height, so that the height difference between the surrounding edge and the surface of the mattress body can be eliminated, and the flatness of the mattress structure can be improved, achieving the purpose of improving user experience. Most importantly, by setting the main air channel at the bottom of the surrounding edge, and making it to secure with the connecting part of the limiting formation, the position of the main air channel can be fixed, effectively avoiding phenomena such as pulling, twisting, or displacement in the use of the main air channel, which is conducive to ensuring the smooth flow of gas inside the main air channel. In addition, the mattress structure is equipped with an elastic filler of a U-shaped structure on the top layer of the lining, with the opening end of the U-shaped structure arranged on a side opposite to the air bag, and with an inclined surface arranged on a position where the two outer side wall of the U-shaped structure meet the bottom; in this way, the deformation and protrusion caused by the mattress structure after inflation in the height direction can be reduced, avoiding the problem of uneven surface of the bed body caused by large deformation of the mattress body, which has high practical value.

Obviously, the above embodiments of the present disclosure are only for the purpose of clearly illustrating the examples provided herein, and are not limiting the embodiments of the present disclosure. For those skilled in the art, different forms of changes or variations can be made based on the above explanation. It is unnecessary and impossible to exhaustively list all implementation examples here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present disclosure shall be included within the scope of protection of the claims of the present disclosure.
