"') can be controlled to increase the height. In this state, the hammock line 401 is connected to the connecting ring 319 formed on each roller 318 of the hammock driving unit 300, and horizontally as shown in FIG. 4c. The inner strap 120 of the length bar 100 is drawn out to extend the length of the frame 1"' so that the hammock 400 is extended long, and the inner strap 212 of the horizontal part 210 of the vertical support 200 at the same time. ) to keep the frame 1"' stable. In addition, in order to use the hammock 400 more widely or to use two or more people together, the cylinder 316 is driven to each cylinder arm 317. The connected rollers 318 may be operated to spread in both directions along the rail 315. Then, the cylinder arm 317 is moved in the same direction for left and right recoil of the hammock 400, for example, one arm ( Each roller 318 by controlling as shown in FIGS. 4D and 4E so that when the 317 is withdrawn from the cylinder 316, the arm 317 of the other side is driven forward and reverse in the direction to be inserted into the cylinder 316 at the same time as shown in FIGS. 4D and 4E. moves in the same direction along the rail 315, and accordingly, the hammock 400 connected to each roller 315 moves left and right so that it can recoil left and right.

On the other hand, although not shown in the drawings, the hammock device of the present invention can be used by installing a cradle for infants on the hammock driving part or the hammock holder in the initial reduced state of the device frame, and also, when sleeping outdoors, the horizontal and vertical support poles You can also use it as a substitute to set up a tent or insect screen. In addition, by adding a timer function to the automatic control of the hammock device, it may be configured to enable recoil of the hammock, adjustment of the length of the hammock, etc. according to a predetermined time.

Although various embodiments of the present invention have been described above, the contents described so far are merely illustrative of some of the preferred embodiments of the present invention, and except as may appear in the claims appended below It is not limited by the above-mentioned content. Accordingly, the present invention understands that many changes, modifications and substitutions of equivalents can be made within the scope set forth in the following claims by those skilled in the art without departing from the spirit and spirit of the invention. will have to
