1. Field of the Invention
The present invention relates to a mattress and, more particularly, to a ventilation mattress, which uses an electric fan to provide currents of air through air vents in the top layer of the outer covering for ventilation. The ventilation mattress can be made in any of a variety of forms for use as a seat mattress, sofa mattress, or bed mattress.
2. Description of the Related Art
Straws and bamboo strips are commonly used for making cooling mattresses. Lying or sitting on a cooling mattress during a hot weather is comfortable at the initial stage. However, the cooling effect of a cooling mattress is gradually reduced with the time in which the user sits or lies on the cooling mattress.
There are also known seat and bed mattresses formed of strings of ball or block elements. These seat and bed mattresses have open spaces in between the ball or block elements for ventilation. However, when sitting or lying on a seat or bed mattress of this design, the user's body will block the open spaces, and the seat or bed mattress become hot within a short time.
In order to eliminate the aforesaid drawbacks, a seat mattress with enforced currents of air is developed. A seat mattress of this design comprises a hard inner layer, a breathing leather covering covered the hard inner layer, and an electric fan. The hard inner layer has air guide grooves adapted to guide air in a particular direction. The leather covering has air holes for exhaust of air. The electric fan is controlled to induce currents of air into the inside of the seat mattress. This design of seat mattress still has drawbacks. Because currents of air are guided in a particular direction, the ventilation effect is limited. Further, because the inner layer is a hard member, it is not comfortable to sit on the seat mattress.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide ventilation mattress, which provides a ventilation effect. It is another object of the present invention to provide a ventilation mattress, which is high compressible. It is still another object of the present invention to provide a ventilation mattress, which can be conveniently adjusted to provide hot air when cold, or cold air when hot. According to one aspect of the present invention, the ventilation mattress comprises an outer bag, the outer bag comprising a top fabric sheet layer, a bottom fabric sheet layer peripherally sealed to the top fabric sheet layer, at least one air inlet respectively extended out of the top fabric sheet layer and the bottom fabric sheet layer, and a plurality of air vents formed in the top fabric sheet layer in communication with the at least one air inlet; at least one flexible tube respectively connected to the at least one air inlet of the outer bag; at least one electric fan respectively installed in the at least one flexible tube and adapted to induce currents of air into the inside of the outer bag; and a fabric stuffing member stuffed in the outer bag between the top fabric sheet layer and the bottom fabric sheet layer, the fabric stuffing member being formed of interwoven nylon fibers and having open spaces for circulation of air through the at least one air inlet and the air vents. According to another aspect of the present invention, electric cooling fans or electric fans with electric heater means may be alternatively used subject to the condition of the weather.
Referring to FIGS. 1˜3, a ventilation mattress 1 is shown comprising an outer bag 11, a fabric stuffing member 13 put in the outer bag 11, an air inlet 12 formed in one side of the outer bag 11, a flexible tube 14 extended from the air inlet 12, and a high-performance fan 15 provided at one end of the flexible tube 14 remote from the air inlet 12. The fabric stuffing member 13 is formed of interwoven nylon fibers 132, having open spaces 1321 in it. The outer bag 11 is formed of top and bottom fabric sheet layers 131, having small air vents 111 in the top side (top fabric sheet layer). The fan 15 comprises an air output port 151 connected to the flexible tube 14, an air input port 152 in communication with the air output port 151, a grille 153 covering the air input port 152, an air filter 1531 mounted in the grille 153, a battery chamber 155, a set of battery cells 1551 mounted in the battery chamber 155, a battery lid 1552 covering the battery chamber 155, and a power cord 154 for connection to an electric socket to obtain the necessary working voltage. The fan 15 can obtain the necessary working voltage either from the set of battery cells 1551, or city power supply via the power cord 154. When starting the fan 15, electric currents are caused to flow from the air output port 151 into the air inlet 12 and then the open spaces 321 in the fabric stuffing member 13, and then to flow out of the outer bag 11 through the air vents 111.

A prototype of ventilation mattress has been constructed with the features of FIGS. 1˜12. The ventilation mattress functions smoothly to provide all of the features discussed earlier.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. For example, the fans used can be cooling fans for use in hot weather, or fans with electric heater means for use in cold weather. Accordingly, the invention is not to be limited except as by the appended claims.
