材６をより低い位置に下降することができる。 The fixing mechanism _S2 can be configured to only prevent the lower support beam member 7 from moving in the upward direction, but can be configured to be able to move up and down with an appropriate stroke below it, or can be configured to be completely unable to move up and down. You can also
In the former case, since the lower end of the fence main body 3 is lowered as the vertical width is shortened during the lowering, the upper support beam member 6 can be lowered to a lower position.

A wrapping part 9 formed with an opening 8 narrower than the outer shape of the
A core rod 10 is fitted into the coiled elastic member 1a inserted into the holding portion 9, and the coiled elastic member 1a is fixed to the upper support beam member 6. Although not shown, the fence body 3
The coiled elastic member 1z constituting the lower end of is also fixed to the lower support beam member 7 using the same structure as described above. These upper and lower support beam members 6 and 7 support guide members 11 provided at both ends thereof, which are fitted into the openings 4 of the guide frame 5 so as to be movable up and down.

容易であるという効果がある。(Effects of the invention) As described above, the present invention basically consists of a structure in which a large number of large pitch coil-shaped elastic members are successively intertwined with each other for each adjacent member, and these are attached to the side of the bed. Since the upper end can be raised and lowered freely, when in use, the upper end is raised by the support member and supported in a wide state, thereby reliably preventing children, etc. on the bed from falling, and when in the stored state. Since the width is narrow, the lowering position of the support member is low, and the floor of the bed is low in height, making it easy for children to get on and off the bed and to make the bed.
