Abstract

Canvas bed with a U-shaped round steel pipe at the back (1) for securing the edge of the fabric (4). The back of the fabric (4) is sewn with a transverse groove the same width as the U-shaped round steel pipe at the back (1) for inserting into the top of the canvas bed. The U-shaped round steel pipe at the bottom back (6) serves as the base for supporting the back of the canvas bed, and there is a U-shaped round steel pipe at the bottom front (9) for supporting the front of the canvas bed. In the securing part of the fabric (4), the bottom left side is secured by sewing a groove on the left side (13) for the end of the left round steel pipe (14) to be inserted into the left groove (13), and the canvas bed has a round steel pipe at the top left (17) that is bent at the end (32) for inserting the rubber edge (29) into the end. In the area of the fabric edge fastening (4), on the right side, the edge of the fabric (4) is sewn with a right-hand groove (20) for the end of the right-hand round steel pipe (21) to be inserted into the right-hand groove (20), and the canvas bed has a round steel pipe on the upper right (22) that is bent at the end (23) for the rubber edge (30) to be fitted onto the end. And in the area of the round steel pipe bent into a U shape at the bottom back (6), there is a left-hand long edge (25) and a right-hand rubber edge (26) fitted on both sides to prevent the canvas bed from sliding, and the round steel bent into a U shape at the bottom front (9) also has a left-hand rubber edge (27) and a right-hand long edge (28) fitted on both sides to prevent the canvas bed from sliding as well.
