MATTRESS HAVING THREE-DIMENSIONAL ELASTIC STRUCTURE

Abstract

A mattress having a three-dimensional elastic structure of the present invention has a structure in which a main elastic body independently contracts and expands by multiple first to fourth auxiliary elastic slits which intersect with each other in left and right directions, front and rear directions, and up and down directions so as to form a three-dimensional air tunnel. Accordingly, when the first to fourth auxiliary elastic slits contract and expand, air is discharged in all directions of the main elastic body through the three-dimensional air tunnel so as to disperse the pressure by a human body, thereby inducing good blood circulation, and heat is released through the three-dimensional air tunnel so as to secure air permeability, thereby inducing maintenance of a proper sleep temperature so as to provide a more comfortable sleep environment.

MODE FOR INVENTION

[0024] In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying FIGS. 1 to 8. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. Accordingly, the shape of components in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same components in each drawing are sometimes illustrated with the same reference numerals. Detailed descriptions of well-known functions and configurations determined to unnecessarily obscure the gist of the present invention will be omitted.

[0025] Referring to FIGS. 1 and 2, a mattress having a three-dimensional elastic structure according to a first embodiment of the present invention is configured to include a main elastic body 10 formed in a rectangular parallelepiped shape and made of one body to have the same thickness; multiple first auxiliary elastic slits 20 that are respectively formed to a predetermined height toward the center of the thickness of the main elastic body 10 at regular intervals in the left and right directions in an upper planar area of the main elastic body 10 and penetrate in the front and rear directions, respectively; multiple second auxiliary elastic slits 22 that are respectively formed to a predetermined height toward the center of the thickness of the main elastic body 10 at regular intervals in the left and right directions in a lower planar area of the main elastic body 10 so as to be disposed between the multiple first auxiliary elastic slits 20, and penetrate in the front and rear directions, respectively; multiple third auxiliary elastic slits 30 that are respectively formed to a predetermined height toward the center of the thickness of the main elastic body 10 at regular intervals in the front and rear directions in the upper planar area of the main elastic body 10, and penetrate in the left and right directions, respectively; multiple fourth auxiliary elastic slits 32 that are respectively formed to a predetermined height toward the center of the thickness of the main elastic body 10 at regular intervals in the front and rear directions in the lower planar area of the main elastic body 10 so as to be disposed between the multiple third auxiliary elastic slits 30, and penetrate in the left and right directions, respectively; and a three-dimensional air tunnel 40 in which the multiple first to fourth auxiliary elastic slits 20, 22, 30, and 32 are all or partly intersected with each other at the center height of the thickness of the main elastic body 10 so that air is circulated in the left and right, front and rear, and up and down directions of the main elastic body 10.

[0026] In this case, the main elastic body 10 is made of a high elastic polymer such as a foamed synthetic resin such as foamed urethane or a non-foamed synthetic resin such as synthetic rubber, silicone, and elastomer.

[0027] When the thickness of the main elastic body 10 is, for example, 110 mm, the multiple first and third auxiliary elastic slits 20, 30 are respectively formed vertically to a depth of 60 mm from the upper surface of the main elastic body 10 toward the center of the thickness of the main elastic body 10, and the multiple second and fourth auxiliary elastic slits 22, 32 are respectively formed vertically to a depth of 60 mm from the lower surface of the main elastic body 10 toward the center of the thickness of the main elastic body 10 so that they intersect the ends of the multiple first and third auxiliary elastic slits 20, 30 by 10 mm. Accordingly, the three-dimensional air tunnel 40 connected to the left and right (horizontal), front and rear (vertical), up and down (depth) is formed.

[0028] When the multiple first auxiliary elastic slits 20 and the multiple third auxiliary elastic slits 30 intersect each other in the upper planar area of the main elastic body 10, a square three-dimensional air tunnel 40 of 10×10 mm is formed. When the multiple second auxiliary elastic slits 22 and the multiple fourth auxiliary elastic slits 32 intersect each other in the lower planar area of the main elastic body 10, and they are alternately intersected in the center between the first auxiliary elastic slits 20 and the third auxiliary elastic slits 30, the square three-dimensional air tunnel 40 of 10×10 mm is formed, so heat is released and elasticity due to air pressure is increased.

[0029] The multiple first to fourth auxiliary elastic slits 20, 22, 30, and 32 are vertically formed to have the same depth or different depths from the planar area of the main elastic body 10 to a predetermined height of the thickness of the main elastic body 10, respectively.

[0030] That is, as shown in FIGS. 1 to 4, when the multiple first to fourth auxiliary elastic slits 20, 22, 30, and 32 have the same depth up to a predetermined height from the upper and lower surfaces of the main elastic body 10 toward the center of the thickness of the main elastic body 10, they all intersect each other to form the three-dimensional air tunnel 40 to allow air circulation in the left and right, front and rear, and up and down directions.

[0031] However, as shown in FIGS. 5 and 6, when, among the multiple first to fourth auxiliary elastic slits 20, 22, 30, and 32, the first auxiliary elastic slits 20 and the fourth auxiliary elastic slits 32 have the same depth so that they reach a predetermined height toward the center of the thickness of the main elastic body 10 and theirs ends intersect each other, and the second auxiliary elastic slits 22 and the third auxiliary elastic slits 30 have the same depth, the depth shorter than the depth of the first and fourth auxiliary elastic slits 20 and 32, so that their ends do not intersect each other at a predetermined height of the center of the thickness of the main elastic body 10, the second and third auxiliary elastic slits 22, 30 do not intersect each other, but intersect indirectly through the first and fourth auxiliary elastic slits 20 and 32.

[0032] That is, the first auxiliary elastic slits 20 formed with a long depth on the upper surface of the main elastic body 10 directly intersect vertically with the fourth auxiliary elastic slits 32 formed with a long depth on the lower surface of the main elastic body 10. On the other hand, the second auxiliary elastic slits 22 formed with a short depth on the lower surface of the main elastic body 10 directly intersect the fourth auxiliary elastic slits 32 formed with a long depth, but indirectly intersect the first and third auxiliary elastic slits 20, 30 formed on the upper surface of the main elastic body 10 through the fourth auxiliary elastic slits 32. The third auxiliary elastic slits 30 formed with a short depth on the upper surface of the main elastic body 10 directly intersect the first auxiliary elastic slits 20 formed with a long depth, but indirectly intersect the second and fourth auxiliary elastic slits 22, 32 formed on the lower surface of the main elastic body 10 through the first auxiliary elastic slits 20.

[0033] In this case, as shown in FIGS. 3 and 4, one horizontal wing part 50 is formed to extend left and right symmetrically with the auxiliary elastic slits 20, 22, 30, 32 interposed therebetween at a predetermined height of the multiple first to fourth auxiliary elastic slits 20, 22, 30, 32 in order to provide a mattress whose elasticity is adjusted according to the user's body type.

[0034] Alternatively, as shown in FIGS. 5 and 6, multiple horizontal wing parts 50 can be formed densely extended at regular intervals up and down while symmetrical left and right with the auxiliary elastic slits 20, 22, 30, and 32 interposed therebetween.

[0035] In addition to the horizontal wing part 50, at least one inclined wing part 52 as shown in (a) and (b) of FIG. 7 or a curved wing part 54 as shown in (a) and (b) of FIG. 8 can be formed at a predetermined height of the multiple first to fourth auxiliary elastic slits 20, 22, 30, 32 in order to provide various mattresses whose elastic force is adjusted according to the user's body type.

[0036] On the other hand, as shown in FIGS. 5 and 6, a memory foam 60 having an air hole formed therein and a filter foam 70 having an air cell are stacked in the mattress having a three-dimensional elastic structure of the present invention.

[0037] That is, the memory foam 60 is formed in a planar shape corresponding to the mattress and is stacked on the main elastic body 10. The filter foam 70 is used to be interposed between the memory foam 60 and the main elastic body 10 or between the multiple stacked main elastic bodies 10.

[0038] As such, the mattress having a three-dimensional elastic structure of the present invention has a structure in which the main elastic body 10 independently contracts and expands by the multiple first to fourth auxiliary elastic slits 20, 22, 30, 32 which intersect with each other in the left and right directions, the from and rear directions, and the up and down directions so as to form the three-dimensional air tunnel 40. Accordingly, when the first to fourth auxiliary elastic slits 20, 22, 30, 32 contract and expand, air is discharged in all directions of the main elastic body 10 through the three-dimensional air tunnel 40 so as to disperse the pressure by a human body, thereby inducing good blood circulation, and heat is released through the three-dimensional air tunnel 40 so as to secure air permeability, thereby inducing maintenance of a proper sleep temperature so as to provide a more comfortable sleep environment.

[0039] On the other hand, the present invention is not limited to the above-described embodiments, but can be implemented with modifications and variations without departing from the gist of the present invention, and the technical idea to which such modifications and variations have been applied should also be regarded as falling within the scope of the following claims.
