Air pocket module and air mattress including same
An air pocket module inserted into an air mattress includes multiple air pockets each having a hollow portion formed therein and configured to inflate due to air inflow or to deflate due to air outflow, and a bottom plate coupled to lower sides of the air pockets and configured to block the hollow portion of each of the air pockets, wherein the air pocket includes: a top surface portion forming a top surface, a side surface portion connected with the top surface portion and forming a side surface, and a contact portion protruding upwardly from a center of the top surface portion.
1. An air pocket module inserted into an air mattress, the air pocket module comprising:
multiple air pockets each having a hollow portion formed therein and configured to inflate due to air inflow or to deflate due to air outflow; and
a bottom plate coupled to lower sides of the air pockets and configured to block the hollow portion of each of the air pockets,
wherein the air pocket includes:
a top surface portion forming a top surface;
a side surface portion connected with the top surface portion and forming a side surface;
a contact portion protruding upwardly from a center of the top surface portion; and
a first connection portion formed at an edge portion of the air pocket where the top surface portion and the side surface portion are connected to each other to connect the top surface portion and the side surface portion to each other, wherein the first connection portion is formed to be inclined from the top surface portion toward the side surface portion,
wherein the side surface portion includes:
a first side surface including two surfaces facing each other, the first side surface having a first reinforcing portion, wherein the first reinforcing portion is configured such that a width thereof decreases gradually from the first connection portion to a lower portion of the first side surface; and
a second side surface including two other surfaces facing each other, the second side surface including a support portion protruding outwardly of the air pocket, a second reinforcing portion positioned within the support portion, and wherein an upper end of the support portion is directly connected with the contact portion to improve supportability of the contact portion.
2. The air pocket module of claim 1 , wherein the first side surface includes a first inflation portion formed concavely toward the hollow portion such that side surface portions of adjacent ones of the multiple air pockets are prevented from coming into contact with each other when the air pockets inflate.
3. The air pocket module of claim 1 , wherein the second side surface includes multiple second inflation portions each formed concavely toward the hollow portion such that side surface portions of adjacent ones of the multiple air pockets are prevented from coming into contact with each other when the air pockets inflate.
4. The air pocket module of claim 3 , wherein the second side surface includes the support portion protruding outwardly of the air pocket at a position between the multiple second inflation portions.
5. The air pocket module of claim 4 , wherein the first reinforcing portion is formed in a curved shape to be inclined inwardly from the first connection portion toward a middle of a lower end of the first side surface; and
the width the first reinforcing portion decreases gradually from the first connection portion to the lower portion of the first side surface so that both sides defining the width of the first reinforcing portion are met at a point in the lower portion of the first side surface.
6. The air pocket module of claim 5 , wherein the second reinforcing portion is formed in a curved shape to be inclined inwardly from the first connection portion toward a lower end of the support portion; and the second reinforcing portion is configured such that a width thereof decreases gradually from the first connection portion to a lower portion of the support portion.
7. The air pocket module of claim 1 , wherein the air pocket includes a second connection portion connected to a lower portion of the air pocket and the bottom plate; and the second connection portion is formed to be inclined outwardly from a peripheral end of the air pocket toward the bottom plate.
8. The air pocket module of claim 1 , wherein the multiple air pockets are arranged in each of a horizontal direction and a vertical direction to form multiple rows and multiple columns, and a first flow passage is provided to allow adjacent air pockets in each row to communicate with each other, and a second flow passage is provided to allow adjacent air pockets in each column to communicate with each other.
9. The air pocket module of claim 8 , wherein the multiple air pockets are arranged in four rows×five columns; and the first flow passage is formed such that the air pockets in each of a first row, a second row, a third row, and a fourth row communicate with each other, and the second flow passage is formed between the first row and the second row such that the air pockets of the first row and the second row communicate with each other.
