Title: Assemblable Foam Material

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to an assemblable material, and particularly to an assemblable foam material. 
     BACKGROUND OF THE INVENTION 
     The decoration works according to the prior art include the work using the foam material as the base material. For example, while laying a carpet, floorboards or woods, a foaming material will be laid firstly on the floor in order to take advantage of material characteristics, such as sound and heat insulation, of the foaming material. Because the size of a foaming material is limited, if a large-area floor is to be laid, a plurality of foam materials has to be jointed to form a large-area foam material. According to the prior art, roughly two works are adopted to form a large-area foam material. The first work pastes a twin adhesive along same edge of the foam materials. By jointing the twin adhesive with the bottom of the adjacent foam material, adjacent foam materials are jointed to form a large-area foam material. However, the jointing structure of the first work described above tends to produce surface roughness and seams at the joints, and thereby making sound and heat insulation unreliable. 
     The second work mainly pastes a thin joint layer on surfaces of each foam material. The length of the joint layer is approximately equal to that of the foam material. When the joint layer is pasted in the foam material, it is shifted relative to the position of the foam material. Namely, one edge of the joint layer falls back on the surface of the foam material, making the other edge of the joint layer protrude the far edge of the foam material. Next, paste a twin adhesive on the surface of the foam material without the joint layer. Thereby, when every two foam materials approach each other, the portion of the joint layer protruding one edge of a foam material touches the surface of the adjacent foam material with the twin adhesive and the two bond together to form a large-area foam material. Nevertheless, the complicated laying processes of said two works increase manufacturing and construction costs, hence unfavorable for promotion. 
     Accordingly, the present invention provides an assemblable foam material, which uses a simple jointing technology to joint a plurality of foam materials for forming a large-area foam material. Thus, the problem described above can be solved. 
     SUMMARY 
     An objective of the present invention is to provide an assemblable foam material, which uses a simple jointing technology to joint a plurality of foam materials and form an assemblable foam material with neat and beautiful joints. 
     In order to achieve the objective described above, the present invention provides an assemblable foam material comprising a plurality of foam materials and a plurality of joint members. The plurality of foam materials uses the plurality of joint members to joint with each other and form an assemblable foam material.
