1. Field of the Invention
The present invention generally relates to a mattress structure, more particularly to a mattress structure that is able to adjust the flexible supporting forces thereof so as to let that different users can be provided with different levels of softness.
2. Description of the Prior Art
Under the leadership of science and technology, the life is always fast and in pressure. At the end of a day, everybody needs a good sleep to completely relax the body for the next day.
Except for work and normal life, 30% time is for sleep for a human being. The quality of a sleep may directly affect the health of the human being. Accordingly, demands to a mattress may then be more than ever. The prior mattresses are mostly made by the way of integration molding, and the softness of a mattress shall be adjusted based on the requirements of a user. It costs a lot as always and is inconvenient. The prior mattress structure has a mattress body and a flexible member in the mattress body, but it is full of disadvantages listed below:
After using a period of time, partial of the flexible member is damaged as a sunken portion so as to affect sleep.
The flexibility of each part of the surface of the prior mattress structure is the same and may not be changed; the flexibility cannot be adjusted according to different users as well, and therefore the ergonomic cannot be met.
Since the flexible member is made by integration molding, a chain reaction can happen. If two people with different sleep habits lie on a bed, one people may be affected by another. Hence, an option for solving the problem is to purchase another mattress structure for more comfortable, but it is definitely not an economic way.
The inventor of the present invention had applied a patent application, titled mattress structure, to USPTO on Sep. 8, 2010, and the application Ser. No. 12/877,275. The patent application adopts two layers of flexible members in order to adjust the hardness of the mattress structure. Frankly speaking, the two layers of flexible members take higher cost of manufacturing and assembling.
The inventor of the present invention has hardly worked on the issue to develop the new mattress structure of the present invention, and it will be discussed as below.
The main objective of the present invention is to provide a mattress structure, which applies the movement of a moving plate and the connections and fixes of fixing members and flexible members in order to adjust the flexible supporting forces of the mattress structure. Thus different users can be provided with different levels of softness.
To achieve the objective, the present invention provides the mattress structure comprises: a mattress body; a fixing plate, being firmly disposed in the mattress body and having a plurality of fixing holes; a moving plate, being disposed in the mattress body and above the fixing plate, the moving plate having a plurality of penetrating holes; a plurality of flexible members, being disposed on the surface of the top end of the moving plate, the bottom ends of the flexible members being corresponding to the penetrating holes; a plurality of fixing members, each of the fixing members having a fastening end and a connecting end, the fastening end going through the penetrating hole and associating with the fixing hole of the fixing plate, the connecting end joining with the top end of the flexible member; and a plurality of lifting devices, being disposed at the bottom of the moving plate, by means of the lifting devices driving the moving plate and the fixing members holding the flexible members, the flexible members being then compressed in order to adjust the flexible supporting forces of the mattress body.
While the user increases the flexible supporting forces of the mattress structure, to start the motors is to drive the power transmission shafts to move the moving plate upwardly. Meanwhile the flexible members are compressed by the moving plate due to the movement of the moving plate. Since each of the flexible members is firmly connected with the fixing member, then one end of the flexible member is fixed and the other end of the flexible member is compressed. Apparently, the flexible member appears a state of squeeze, and the flexible supporting force is increased. On the contrary, when the user wants to decrease the flexible supporting forces, through the motors of the lifting devices driving the moving plate downwardly is to decrease the squeeze condition of the flexible members, so that the flexible supporting forces are decreased.
Preferably, the fastening end of the fixing member is shaped as a ladder-type structure so as to let the fixing member be fixed in the fixing plate while the fastening end is inserted into the fixing hole; the connecting end is shaped as an L-type structure in order to hook the top end of the flexible member for connecting the fixing member and the flexible member.
Preferably, the lifting devices are disposed at the four corners of the moving plate.
Preferably, the lifting devices are disposed at the center of the moving plate.
Preferably, the power transmission shaft is a screw rod.
Preferably, the top layer of the flexible member is a flexible layer, a wrapper is covered around the peripheries of the mattress body. So that the effect of sleep is raised.
Preferably, the lifting device is connected with a remote receiver and a remote emitter, an operator uses the remote receiver to control the up and down actions of the lifting device by means of the remote emitter transmitting signals to the remote receiver.
Other and further features, advantages, and benefits of the invention will become apparent in the following description taken in conjunction with the following drawings. It is to be understood that the foregoing general description and following detailed description are exemplary and explanatory but are not to be restrictive of the invention.
