  As shown in FIGS. 20 to 21, the base portion side hook 54 has a fulcrum portion 55 that contacts the inner peripheral surface of the main shaft 5 at the tip, a push button 56 that protrudes outward from the main shaft 5 at the base portion, A body portion 57 that is inserted through the main shaft 5 is formed. Between the fulcrum portion 55 and the push button 56, a main hook 58 is disposed so as to protrude from the main shaft 5 at the lower portion, and a sub hook 59 is disposed so as to protrude from the main shaft 5 at the upper portion.

  As shown in FIGS. 21 to 22, the push button 56 is disposed through a push button groove 503 formed in the lower portion of the main shaft 5. The main hook 58 is disposed so as to be able to enter and exit from a main hook groove 504 formed in the main shaft 5. The sub hook 59 is disposed so as to be able to enter and exit from a sub hook groove 505 formed in the main shaft 5. The sub hook 59 is formed so that the amount of outward projection of the main shaft 5 is shorter than the main hook 58.

  The base portion side hook 54 makes the fulcrum portion 55 abut on the inner peripheral surface of the main shaft 5 so that the back portion 571 side between the fulcrum portion 55 and the sub hook 59 is opposite to the fulcrum portion 55. The lower end portion of the body portion 57 is tilted to the left in FIG. 20 while being in contact with the inner peripheral surface. That is, the main hook 58 and the sub hook 59 are configured to move toward the main shaft 5 when the push button 56 is pushed toward the inner peripheral surface side of the main shaft 5. The main hook 58 and the sub hook 59 are formed so as to be locked in a hook locking groove 115 (see FIGS. 9 and 21) formed immediately above the hand pressing portion 112 of the slider shaft 11. When the hook locking groove 115 is released from the main hook 58 by the operation of the push button 56, the slider shaft 11 is raised by the urging force of the compression coil spring 53, but the hook locking groove 115 is locked to the sub hook 59. The ascent of the slider shaft 11 is temporarily stopped. When the push button 56 is further pushed in a state where the hook locking groove 115 is locked to the sub hook 59, the hook locking groove 115 is released from the sub hook 59, and the slider shaft 11 is raised again. As a result, the main bone 12 and the waterproof cloth 13 are opened, and the umbrella 1 is fully opened by further pushing up the support portion 141 of the cylinder shaft 14.

  The sub-hook 59 once stops the ascent of the slider shaft 11 to prevent the umbrella opening / closing portion 3 from being suddenly opened. Therefore, it is possible to prevent a third person from being at risk.

  Note that the push button 56 of the embodiment is in an overlapping position before the unlocking operation lever 29 of the depot storage device 20 is operated, and the push button 56 is disposed inside the unlocking operation lever 29. As a result, the automatic extension device 50 cannot be operated before operating the tip storage device 20, and a safety measure can be taken.

  Further, as shown in FIGS. 22 to 23, the main shaft 5 is formed with a stopper guide slit 506 at one location in the longitudinal direction, and is connected to the main stopper 113 by the first stopper plate 51. 511 is disposed through the stopper guide slit 506.

  Next, the operation of the umbrella 1 configured as described above will be described.

  In the state in which the umbrella opening / closing part 3 is closed, as shown in FIG. 1, the hand pressing part 112 of the slider shaft 11 is in a position close to the handle part 6 of the main shaft 5, and the handle part on the base part side of the main shaft 5. 6 is installed. The main bone 12 and the waterproof cloth 13 are closed upward. In this state, as shown in FIG. 13, the tip 131 of the waterproof cloth 13 is covered and stored by the tip storage ring 23 of the tip storage device 20. As shown in FIG. 20, the hook locking groove 115 of the slider shaft 11 is locked to the main hook 58 of the automatic extension device 50. The handle 6 is prevented from rotating with the main shaft 5.

  Further, in this state, the surface of the waterproof cloth 13 (the surface directly wetted by rain) is partly folded in the cloth storage cylinder 142 of the cylinder shaft 14 together with the main bone 12.

  Next, when opening the umbrella opening / closing part 3, first, the unlocking operation lever 29 of the dew storage device 20 is moved in the horizontal direction along the horizontal slit 281 formed in the main shaft 5, and then in the vertical slit 282. Store in. Since the unlocking operation lever 29 housed in the vertical slit 282 is open at the upper portion, the push-up rod 25 is moved upward by the biasing force of the lower coil spring 30. As a result, the tip storage ring 23 connected at the top of the push-up rod 25 is detached from the tip 131 of the waterproof cloth 13, and the tip 131 is released from the tip storage ring 23. Next, it operates so that the push button 56 of the automatic extension device 50 may be pushed in.

  As described above, when the push button 56 of the embodiment is operated, it can be operated for the first time by releasing the lock release operation lever 29 of the dew tip storage device 20 from the position overlapping the push button 56.

  By pushing the push button 56, the main hook 58 is released from the hook locking groove 115 of the slider shaft 11. Then, the slider shaft 11 slides with respect to the main shaft 5 by the urging force of the compression coil spring 53 and moves upward together with the cylinder shaft 14. Since the compression coil spring 53 is in a state of being compressed to the maximum extent, its urging force is large. Therefore, the slider shaft 11 performs a rapid upward movement.

  However, the sudden upward movement of the slider shaft 11 stops when the hook locking groove 115 is locked to the sub hook 59. By further pushing the push button 56, the hook locking groove 115 is released from the sub hook 59 and starts to move upward again.

  When the slider shaft 11 and the cylinder shaft 14 are raised, the protruding piece 144 of the cylinder shaft 14 penetrates the second long groove 114 of the slider shaft 11 and engages with the first long groove 501 of the main shaft 5. The slider shaft 11 and the cylinder shaft 14 move upward without rotating with respect to the main shaft 5. When the cylinder shaft 14 reaches the upper end position of the main long shaft 501 and the first long groove 501 of the main shaft, the cylinder shaft 14 stops rising and the slider shaft 11 rises with respect to the cylinder shaft 14.

  At this time, the tension coil spring 17 that is hooked between the main bone support portion 113 and the support shaft support portion 141 is in a compressed state.

  Then, as shown in FIG. 4, when the slider shaft 11 rises with respect to the cylinder shaft 14 in this state, that is, the main bone support portion 113 is moved upward against the biasing force of the tension coil spring 17 (tip support cap). 22), the cylinder shaft 14 moves downward relative to the slider shaft 11, and pushes down the fulcrum support portion 141 downward. Since the first support frame 15 pivotally supported by the support frame support part 141 is hinged to the main bone 12, the main bone 12 is pulled down. Accordingly, as shown in FIG. 2, the first support frame 15 is rotated in the direction of expanding with respect to the support frame support unit 141, and the main bone 12 is rotated in the direction of expanding with respect to the main frame support unit 113. The Further, the second support 16 slides in the support insertion groove 151 of the first support 15 from the main bone 12 side toward the support supporting portion 141 side.

  Further, when pressure is continuously applied to the slider shaft 11, the main bone support portion 113 comes into contact with the tip support cap 22, and the second support 16 moves to the bent portion 152 of the support shaft insertion groove 151 and moves to the main bone 12. And the 1st support frame 15 is hold | maintained in the open state.

  Next, the operation when closing the umbrella opening / closing part 3 will be described. When closing the umbrella opening / closing part 3, the hand pressing part 112 of the slider shaft 11 is pulled to the base part side of the main shaft 5. Then, the urging force of the tension coil spring 17 acts in a direction in which the main bone support portion 113 and the support shaft support portion 141 are brought close to each other. That is, the main bone support part 113 is separated from the tip support cap 22, the first support frame 15 is rotated in the closing direction with respect to the support structure support part 141, and the second support frame 16 is inserted into the support frame insertion groove. 151, the main bone 12 is slid toward the pivot point side. On the other hand, the main bone 12 also rotates in the closing direction with respect to the main bone support portion 113 to move the first support frame 15, the second support frame 16 and the main frame 12 together with the waterproof cloth 13 toward the main shaft 5 side. To do.

  Then, when the main bone support portion 113 is stored in the cloth storage tube portion 142 of the cylinder shaft 14, the central portion side main portion of the main bone 12 together with the base portion of the waterproof cloth 13 is guided into the cloth storage tube portion 142. It is stored while being guided by the section 143. Since the wavy guide portions 143 are formed in the same number as the main bones 12, the base portion of the waterproof cloth 13 does not cause a biased overlap around the body portion 111 of the slider shaft 11. It is stored along. Therefore, the waterproof cloth 13 can be closed smoothly.

  Further, when the slider shaft 11 is moved downward, the protruding piece 144 of the cylinder shaft 14 has a second long groove 114 formed in the slider shaft 11 bent at the lower portion thereof, so that the inside of the cloth storage cylinder portion 142 of the waterproof cloth 13 can be obtained. Before the storage is completed, the waterproof cloth 13 is wound, so that the waterproof cloth 13 can be stored more smoothly.

  When the slider shaft 11 is moved to the lowest position and the hook locking groove 115 of the slider shaft 11 is locked to the main hook 58 of the base side hook 54, the unlocking operation lever 29 of the dew storage device 20 is moved to the vertical slit. Moving from 282 to the horizontal slit 281, the tip 131 of the waterproof cloth 13 is covered with the tip storage ring 23. As a result, the umbrella opening / closing part 3 (umbrella 1) can be closed. Thereafter, when entering the room, the handle 6 is detached and attached to the front end side of the main shaft 5. This operation is performed by moving the cover ring 41 attached to the handle 6 downward to reveal the covered detachable pin 42 on the surface and removing it from the handle 6. This means that the short pin 422 is pulled back from the long pin 421 after being folded back along the axial direction of the long pin 421. If the attachment / detachment pin 42 is attached / detached, it is attached to the front end side of the main shaft 5 as it is.

  Since the closed umbrella opening / closing part 3 has rainwater attached to the surface side of the waterproof cloth 13, the rainwater accumulates inside the umbrella opening / closing part 3, that is, the outer surface of the closed umbrella opening / closing part 3, that is, Rain water is not attached to the back side of the waterproof cloth 13. Therefore, if the rainwater stored inside the umbrella opening / closing unit 3 is discarded in an appropriate place without influence, for example, even if it is carried indoors, other people will not be disturbed.

  As described above, in the reverse closing umbrella 1 according to the embodiment, the second support frame 16 that slides the first support frame 15 is provided between the main frame 12 and the first support frame 15. When the opening / closing part 3 is opened and closed, the amount of movement of the slider shaft 11 can be reduced to perform smooth opening and closing. Since the second support 16 is pivotally attached to the first support 15 so that one end thereof is slidable and the other end is attached to the main bone 12, the second support 16 can be arranged on the distal end side of the main bone 12. Therefore, since the main bone 12 can be supported by the second support 16 together with the first support 15, the strength when the main bone 12 is opened can be increased, and accordingly, the length of the main bone 12 is made longer than before. can do. Therefore, the waterproof cloth 13 can be enlarged and the rain guard can be widened. In addition, the fact that the strength can be increased when the main bone 12 is opened makes the opening / closing action of the umbrella opening / closing part 3 smooth.

  Further, in the reverse closing umbrella 1 of the embodiment, when the umbrella opening / closing part 3 is opened, the protruding piece 144 formed on the inner peripheral surface of the cylinder shaft 14 moves along the first long groove 501 of the main shaft 5. The movement is stopped at the upper end. Since the slider shaft 11 continues to move, the main bone 12 and the waterproof cloth 13 are opened. At this time, by providing the protruding piece 144 in the cylinder shaft 14, a stopper member having a stopper function for the slider shaft is not disposed on the main shaft 5 when the cylinder shaft 14 slides with respect to the slider shaft 11. For this reason, there is no risk of entanglement with the waterproof cloth 13 by the main shuff 5 and the umbrella opening / closing part 3 can be opened and closed smoothly.

  Furthermore, since the reverse closing umbrella 1 of the embodiment includes the tip storage device 20, the tip 131 of the waterproof cloth 13 is stored in the tip storage ring 23 when the umbrella opening / closing part 3 is closed. Can do.

  Moreover, since the reverse closing umbrella 1 of the embodiment includes the attachment / detachment device 40 for the handle 6, the handle 6 is attached to the base of the main shaft 5 when used in the rain, and the umbrella 1 is carried around. The raindrops collected on the waterproof cloth 13 can be walked in the room while being attached to the front end side of the main shaft 5 and stored in the umbrella 1.

  Moreover, since the reverse closing umbrella 1 of the embodiment includes the automatic extension device 50, the main bone 12 and the waterproof cloth 13 can be automatically opened by pushing the push button 56 near the handle 6. . Accordingly, since one-touch operation can be performed with one hand when getting off the vehicle, it is difficult to get wet in the rain when the umbrella opening / closing part 3 is extended.

  In addition, it is possible to further prevent rain from entering by folding the tip of the waterproof cloth 13 downward in the umbrella opening / closing part 3. That is, as shown in FIGS. 24 to 25, the umbrella opening / closing portion 3 </ b> A of the second form includes a main shaft 5, a slider shaft 11 that externally travels on the main shaft 5, and the slider shaft 11, as in the previous form. And a cylinder shaft 14 that externally travels to form a triple shaft structure. A main bone support portion 113 is disposed on the distal end side of the slider shaft 11, and a support shaft support portion 141 is disposed on the base side of the cylinder shaft 14. Is arranged.

  A plurality of the main bones 12A are arranged radially around the main bone support portion 113, and a waterproof cloth 13 is attached to the outer surface. The main bone 12 </ b> A is divided into a main bone main body 121 on which a wide portion of the waterproof cloth 13 is mounted and a main bone base portion 122 fixed to the main bone support portion 113, and the distal end of the main bone main body 121. The main bone distal end 121a is pivotally mounted on the portion so that the main bone distal end 121a can be bent downward. The main bone main body 121 and the main bone base portion 122, and the main bone main body 121 and the main bone tip portion 121 a are pivotally attached by the pivot pin 123.

  15 A of 1st skeleton is provided with the 1st link part 15a pivotally supported to the main bone 12 side, and the 2nd link part 15b pivotally supported to the fulcrum support part 141 side. The 1st link part 15a and the 2nd link part 15b are connected with the pivot pin 123, and comprise the 1st support frame 15A so that bending is possible.

  One end of the second fulcrum 16A is pivotally supported by the main bone main body 121 of the main bone 12A, and the other end is pivotally supported by the pivot pin 123 on the second link portion 15b of the first fulcrum 15A. Further, the main frame 12A and the first support frame 15A are pivotally supported at one end of the auxiliary support frame 16B by a pivot pin 123 at the connecting part between the first link part 15a and the second link part 15b of the first support frame 15A. At the same time, the other end of the auxiliary fulcrum 16B is pivotally supported by a pivot pin 123 to the main bone distal end 121a.

  Thus, in order to open the umbrella, the slider shaft 11 is slid toward the distal end side with respect to the main shaft 5, and is further slid to support the main bone support portion 113 of the slider shaft 11 to the support shaft of the cylinder shaft 14. Therefore, the main bone 12A is pushed apart. As a result, the main bone base portion 122, the main bone main body 121, the main bone tip portion 121a, the first link portion 15a of the first support frame 15, the second link portion 15b, and the auxiliary support frame 16B are respectively connected by the pivot pins 123. Thus, the main bone 12A is inverted outward. Therefore, the main bone 12A acts on the fully open state of FIG. 24 from the fully open state of FIG. 25, and the main bone distal end 121a can be bent inside the umbrella opening / closing part 3A. Can be further prevented.

  When closing the umbrella, the main bone 12A can be bent between the main bone main body 121 and the main bone base portion 122.
