Rather than losing, the first and second bed sheets 100a and 100b are always in an 'X' shape, staggered from one another, regardless of whether they are folded or unfolded.

Meanwhile, in the receiving grooves 102a and 102b formed at the bottoms of the first and second bed sheets 100a and 100b, the support frame 122 fitted into the support grooves 131 of the fixing part 130 is loosened. A separate fixing device 140 is further installed to forcibly fix the support frame 122 to the fixing part 130 so as to prevent the same.

The fixing device 140 includes a bracket 141, a link 142, first and second connection pieces 143 and 144, a spring 145, and a hook 146.

The bracket 141 is bolted to the bottom surface of the receiving groove (102a, 102b) spaced from the fixed portion 130 by a predetermined distance.

In addition, one end of the bracket 141 is hingedly coupled to the link 142, which is a connecting member, so as to be rotatable about a hinged portion of the bracket 141.

At this time, one side of the link 142 is formed with a pressing portion 142a having a constant curved shape to be pressed by the user's hand.

 In addition, the other end of the link 142 on the opposite side of the bracket 141 has a structure in which the hook 146 detachable from the fixing part 130 is connected through the first and second connection pieces 143 and 144.

In this case, each of the first and second connection pieces 143 and 144 is hinged at each end to the link 142 and the fixing part 130, and the opposite ends are coupled through the spring 145 in a state in which they are opposed to each other. It is structured.

At each end coupled through the spring 145, support jaws 143a and 144a, which are portions of which the width of the end is extended, are formed so that both ends of the spring 145 can be supported.

Accordingly, when the first and second connection pieces 143 and 144 are pulled and tensioned in opposite directions to each other, the support jaws 143a and 144a formed at the ends of the first and second connection pieces 143 and 144 may be used. As the spring 145 is elastically compressed, relative movement is made.

A protruding end of the fixing part 130 is formed with a wedge-shaped locking jaw 132, and an end of the hook 146 has a shape corresponding to the locking jaw 132 and is attached to or detached from the locking part 146a. The engaging portion 146a is formed.
