Abstract

The canvas bed with a round steel pipe that is bent into a U-shaped back (1) for fixing the edge of the fabric (4) behind the sewing of the fabric (4) as a horizontal slit equal to the The width of the round steel tube that is bent into the back U-shape (1) for inserting the top of the trampoline. Round steel pipe that is bent into a U-shape below the back (6) for the support of the canvas bed at the back. And there will be a round steel pipe that is bent into a U-shape below the front (9) for the front canvas bed support. As for the fixing of the fabric (4), the bottom left is fixed by the edge of the fabric (4), the bottom left is sewn into a groove on the left (13) for the end of the round steel pipe core. The left side (14) is inserted into the left channel groove (13) and the canvas bed has a top left round steel tube core (17) that is bent at the end (32) for guiding the rubber edge (29) to be worn at the end. say As for fixing the edge of the right fabric (4), which is on the other side, the edge of the fabric (4) is sewn into a groove on the right side (20) for the end of the right round pipe (21). Inserted into the right channel groove (20) and the trampoline has a top right round steel tube core (22) that is bent at the end (23) for the rubber edge (30) to be worn at the end. And for the round steel pipe that is bent into a U-shaped bottom, the back (6) has the left long edge (25) and the right rubber edge (26) worn on both sides to prevent the trampoline from sliding. The U-shaped round steel below the front (9) is also put on the left side (27) and the long right edge (28) to prevent the trampoline from moving as well.
