This application claims priority to Chinese Application No. 201611040756.4 filed on Nov. 21, 2016, the entire contents of which are hereby incorporated by reference.
The present invention relates to the field of cushions for daily use, and in particular to a cushion.
Cushions are comfortable to use, and have a decorative function, and shapes are mainly square, round and elliptic.
The material is selected from cotton cloth, flannelette, brocade or linen, and the most comfortable material is memory foam material.
At present, cushion cores used in cushions often adopt sponge. However, if the density of the adopted sponge is high, hardness will be increased inevitably, water permeability and air permeability will become poor, and elastic property will be poor. If the density of the adopted sponge is low, hardness will be decreased, air permeability will be improved, nevertheless, heavy weight cannot be borne, the sponge can be compacted easily, increasing the sponge density of the pressed area in another way, as a result, the local density of the sponge of the area in actual use is high, hardness is increased, water permeability and air permeability become poor, elastic property is poor, and the comfort of the sponge in use will be decreased as well.
Moreover, the sponge used by conventional cushions is poor in water permeability and air permeability, and cannot be washed directly with water as it can easily absorb water.
The present invention provides a cushion, so that the defects of conventional cushions, poor water permeability and air permeability and incapability of being washed directly with water, of conventional cushions are solved.
In order to solve the above-mentioned problems, the present invention discloses a cushion, which comprises: a cushion core adopting blasted sponge, and an outer cover layer wrapping the outer layer of the cushion core; and the outer cover layer adopts a fiber material which is of a reticular structure.
The novel cushion designed by the present invention, which adopts the blasted sponge structure, is convenient to wash directly with water and has super air permeability.
Alternatively, the cushion core comprises a main bearing area and an auxiliary bearing area.
Alternatively, the cushion further comprises a reinforcing skeleton, the reinforcing skeleton comprises a plurality of bone bridges, and each bone bridge comprises an arch base and an arch bridge; the arch bases are located at two side-by-side corners of one side of the cushion core, and are close to one side of the main bearing area; one end of each arch bridge is connected to the arch base, and the other end extends to the diagonal opposite corner of the other side of the cushion core, and is close to one side of the auxiliary bearing area. The main bearing area and the auxiliary bearing area comprised by the arranged cushion core and the reinforcing skeleton are arranged differentially according to magnitudes of different borne forces. Moreover, the structure of the reinforcing skeleton effectively prevents the defect that after conventional sponge is pressed to deform, the local sponge density of the stressed area is increased, as a result, the local density of the sponge of the area in actual use is high, hardness is increased, water permeability and air permeability become poor, elastic property is poor, and the comfort of the sponge in use will be decreased as well.
Alternatively, the number of the bone bridges is two, and the two bone bridges are arranged crisscross intersected; and two hollow elastic pieces which are superposed vertically are arranged under the intersection between the two bone bridges.
As the two bone bridges are arranged crisscross intersected and the two hollow elastic pieces which are superposed vertically are arranged under the intersection between the two bone bridges, the compression resistance of the main bearing area is higher, and elasticity is better.
Alternatively, each hollow elastic piece is a hexagonal hollow elastic plastic piece, and the elastic coefficient of the elastic plastic piece is 1.2 times the elastic coefficient of the blasted sponge. As the elastic coefficient which is 1.2 times is set, comfort is better.
Alternatively, each arch base is provided with a plurality of arch holes. The arrangement of the plurality of arch holes further reduces the weight of the arch base, and enhances compression resistance.
Alternatively, each arch bridge is provided with a plurality of air-permeable slots.
Alternatively, each air-permeable slot is rectangular. The arrangement of the rectangular air-permeable slots effectively improves the air permeability of the local areas of the arch bridges.
Alternatively, the outer cover layer is provided with an opening, and the opening can be opened and closed by a zipper.
Compared with the prior art, the present technical solution has the following advantages:
The novel cushion designed by the present invention, which adopts the blasted sponge structure, is convenient to wash directly with water and has super air permeability.
In addition, the main bearing area and the auxiliary bearing area comprised by the arranged cushion core and the reinforcing skeleton are arranged differentially according to magnitudes of different borne forces. Moreover, the structure of the reinforcing skeleton effectively prevents the defect that after conventional sponge is pressed to deform, the local sponge density of the stressed area is increased, as a result, the local density of the sponge of the area in actual use is high, hardness is increased, water permeability and air permeability become poor, elastic property is poor, and the comfort of the sponge in use will be decreased as well. As the two bone bridges are arranged crisscross intersected and the two hollow elastic pieces which are superposed vertically are arranged under the intersection between the two bone bridges, the compression resistance of the main bearing area is higher, and elasticity is better.
As the elastic coefficient which is 1.2 times is set, comfort is better. The arrangement of the plurality of arch holes further reduces the weight of the arch base, and enhances compression resistance. The arrangement of the rectangular air-permeable slots effectively improves the air permeability of the local areas of the arch bridges.
