  However, conventional umbrellas are difficult to disassemble for repair or disposal and difficult to recycle. In particular, in the automatic opening umbrella as described in Patent Document 1, a powerful coil spring is mounted between the middle and lower crosspieces, so that the elastic force of the coil spring is completely reduced. If it is not possible to break down in a de-energized state, it is not only difficult to break down, but it is also dangerous.

  Moreover, also in the hand-opening umbrella, there is a demand for a structure of a center bar that can easily remove the supporting bone from the lower rack.

  In view of the above-described circumstances, an object of the present invention is to provide a recycle umbrella that is easy and safe to remove a support bone from a bottom or middle crosspiece.

  In the following description, the upper part or the upper part means the side of the umbrella and the lower part or the lower part means the hand side of the umbrella.

  In the recycle umbrella according to the present invention, a stopper pin that prescribes a sliding upper limit on the center rod when the slide wheel that is slidably fitted to the center rod by pivotally supporting the base portion of the support bone is opened, The sliding rod is provided on the middle rod so as to be able to protrude and retract with respect to the outer peripheral surface of the middle rod so as to be able to slide upward beyond the sliding upper limit.

It consists of a lathe main body that is separably coupled to the material. When the lower pin is below the stopper pin, the support bone pivot member and the potter's wheel main body cannot be separated from each other and the support pin is slid upward beyond the stopper pin. It is preferable that the bone support member and the potter's wheel body are separable so that the root portion of the support bone can be released.

  In addition, a second stopper pin is provided at the lower end portion of the middle rod that is inserted into the middle rod insertion hole at the hand so as to be able to protrude and retract with respect to the outer circumferential surface of the middle rod, and the inner circumference of the middle rod insertion hole at the hand It is preferable that a concave portion is formed on the surface for engaging the second stopper pin protruding from the outer peripheral surface of the center rod to lock the center rod in the center rod insertion hole at hand. And it is preferable that the pore which can insert the pin of the removal jig | tool connected to this recessed part is opening to the outer peripheral surface at hand.

  According to the present invention, when the umbrella is disassembled, it is easy to remove the support bone from the slide wheel by sliding the slide wheel upward from the stopper pin. In the automatic opening umbrella, the middle wheel is used as the stopper pin. By sliding further upward, the resilient force of the powerful coil spring that is retracted between the bottom and the bottom can be de-energized, so the umbrella can be safely disassembled.

  Also, even in the hand-open umbrella, when the lower crosspiece is below the stopper pin, the support bone pivot member and the crosspiece main body cannot be separated, and slides upward beyond the stopper pin. By preventing the unintentional separation between the support bone pivot member and the lower crossbone body during use of the umbrella by configuring the support bone pivot support member and the potter's wheel body to be separable when the Can do.

  Further, a second stopper pin is provided at the lower end portion of the middle rod to be inserted and inserted into the middle rod insertion hole at hand so as to be able to protrude and retract with respect to the outer circumferential surface of the middle rod, and the inner circumference of the middle rod insertion hole at hand.

As a result, as shown in FIG. 11B, the root portion of the support bone 8 comes out of the support bone intervention groove 80 of the lower crossbone body 56, and the lower crossbone body 56 can be rotated relative to the support bone pivot member 54. Become.

  (2) Hold the support bone support member 54 with the finger of one hand, pick the armor body 56 with the finger of the other hand, rotate it counterclockwise when viewed from below, and then pull downward. The armor body 56 is removed from the support bone support member 54, and the root portions of all the support bones 8 are removed from the support bone support member 54.

  (2) Turn the Jinka 5 in the loosening direction and remove it from the cylindrical portion 31 of the upper body 18 and remove it from the middle rod 2, and then remove the main bone removal prevention nut 22 from the cylindrical portion 31, The part is removed from the main bone support disk 20, and the main bone 4 is removed from the center rod 2 together with the fabric S and the support bone 8. At this time, all the tips 9 are removed from the distal ends of the main bones 4, and the fabric S is removed from the main bones 4 by pulling out the loop-shaped pieces 96 of the fabrics S to the distal ends of the respective parent bones 4.

  (3) The main bone pivot disk 20, the upper skull body 18, the support bone pivot member 54, and the lower skull body 56 are removed upward from the middle bar 2.

  (4) Using a jig 94 as shown in FIG. 20, the pin body 17b is pressed against the urging force of the coil spring 17c with the tip of the pin 94a, and the pin body 17b is withdrawn from the locking hole 92. Then, the lower end of the middle bar 2 is pulled out from the hand 10.

  In this way, the umbrella 1 can be completely disassembled.
