Please refer to Figures 1 to 5, which is the first embodiment of the umbrella of the present invention, which includes a rotatable middle rod 10, an upper nest 20, a lower nest 30, an umbrella rib 40, and an umbrella cloth 50 , Two first screws 60, a delay actuator 70, a second screw 80, an umbrella cover 90 (as shown in Figure 9), a support 100, an umbrella handle group 110, a core gear 120 and a drive Piece 130.

The middle rod 10 has a hollow screw hole 11 and a middle rod gear 12 arranged at the bottom end thereof. The upper nest 20 is pivoted on the top end of the middle rod 10, and when the middle rod 10 rotates, the upper nest 20 remains fixed. The lower nest 30 is slidably arranged in the middle section of the middle rod 10; in a possible embodiment, an elastic member (not shown) can be additionally arranged between the upper and lower nests to allow the lower nest to have the potential to move in the upper nest direction . As shown in Figure 3, the ribs 40 include an upper rib group 41 and a lower rib group 42 (only one is shown in Figure 3 as an illustration). One end of the upper rib group 41 is connected to the upper nest 20, and the lower rib group 42 The two ends are respectively connected to the lower nest 30 and the upper rib group 41, and the umbrella cloth 50 is laid on the upper rib group 41 (as shown in Figure 9); in this embodiment, the rib 40 is a three-fold rib; in other possibilities In the embodiment, the ribs can be other multi-fold ribs, such as two-fold or four-fold ribs.

One end of the two first screws 60 is rotatably connected to the upper nest 20, and the other end is provided with a first screw gear 61. The two first screws 60 are arranged in parallel and have the same pitch, and the lower nest 30 has two screw holes without threads. 31 for the first screw 60 to pass through. In other possible implementations, the umbrella can be changed to have more than one first screw, which is not limited to what is exemplified in this embodiment.

The delay actuator 70 is slidably arranged on the middle rod 10 and located below the lower nest 30. The delay actuator 70 has at least one first screw hole 71, the number of which depends on the number of the first screw 60, and the first screw 60 is screwed In the first screw hole 71, when the first screw 60 rotates, the delay actuator 70 can be axially displaced relative to the middle rod 10, and the lower nest 30 is located in the stroke of the delay actuator 71 axially displaced toward the upper nest 20, Therefore, when the delay actuator 71 is displaced upward in the axial direction, the lower nest 30 can be pushed to move in the direction of the upper nest 20 to perform an umbrella opening action. In addition, the lower nest 30 and the delay actuator 70 can be connected by a flexible connecting bar 140, so that when the first screw 60 rotates in the reverse direction, the delay actuator 70 can pull the lower nest 30 through the connecting bar 140. Move away from the upper nest 20 to perform the umbrella action; in addition, if there is an elastic member between the upper and lower nest, as long as the delayed actuator continues to move in the direction of the upper nest, the lower nest itself can pass the elastic member The provided elastic force moves upward without the need to use a delay actuator to push.

The second screw 80 is screwed in the hollow screw hole 11 so that when the middle rod 10 rotates, the second screw 80 can be axially displaced relative to the middle rod 10. The umbrella cover 90 is used to accommodate the umbrella cloth 50, and the support 100 is connected between the second screw 80 and the umbrella cover 90, so that the second screw 80 and the umbrella cover 90 can be axially displaced synchronously. In other words, when the middle rod 10 rotates, the second screw 80 can drive the umbrella cover 90 to move axially relative to the middle rod 10, and the direction of axial displacement of the delay actuator 70 and the second screw 80 is always opposite, that is, when the umbrella is opened , The umbrella cover 90 can be synchronously retracted downwards; when the umbrella is retracted, the umbrella cover 90 can be synchronously moved upwards until the umbrella cloth 50 is covered. In a possible implementation, the umbrella cover may have an upper cover for closing the end adjacent to the upper nest when the umbrella is in the retracted state, so as to prevent the leakage of water droplets.

The umbrella handle set 110 is telescopically inserted in the center of the second screw 80 and one end of the umbrella handle set 110 is connected to the upper nest 20. Specifically, the umbrella handle set 110 may have a handle 111 and a multi-section telescopic tube 112, such as three sections. When the second screw 80 moves downwards in a direction away from the upper nest 20 relative to the middle rod 20, the second screw 80 can push the handle 111 to move downward to extend the multi-section telescopic tube 112; or, as long as the stroke Without being hindered by the second screw 80, the user can extend or shorten the umbrella handle set 110 by himself.

The core gear 120 meshes with the first screw gear 61 and the middle rod gear 12 to drive the first and second screws 60 and 80 to rotate. The driving member 130 is connected to the core gear 120 to drive the core gear 120 to rotate. In this embodiment, the driving member 130 includes a shaft 131 and a turntable 132. The shaft 131 is connected between the core gear 120 and the turntable 132. The sleeve 90 is provided with a long slot 91 for the shaft 131 to pass through. The turntable 132 can be manually rotated by the user, so that the user can open and retract the umbrella by rotating the turntable 132. In other possible embodiments, the driving part may be a combination of a motor and a reduction gear, so that the core gear is driven by electric power. In this case, the driving part may be arranged in the umbrella cover, and the umbrella cover may not be provided with a long groove.

In order to improve the structural strength, the umbrella may further include a storage box 150. The core gear 120, the rod gear 12, and the first screw gear 61 are all located in the storage box 150; in this embodiment, the storage box 150 has a rectangular shape. Crossing the outer contour, four sliding grooves 92 are formed on the inner surface of the umbrella cover 90, and the four corners of the storage box 150 are slidably disposed in the sliding grooves 92, so that the umbrella cover 90 can move axially more stably.

Figures 4 and 5 show the umbrella state of the umbrella. At this time, most of the umbrella mechanism is housed in the umbrella cover 90.

As shown in Figures 6 and 7, when the user turns the turntable 132, the core gear 120 is driven to rotate, and the rod 10 and the first screw 60 are driven to rotate through the rod gear 12 and the screw gear 61, respectively. The rotating rod 10 drives the second screw 80 to move downward in the axial direction, and the rotating first screw 60 drives the delay actuator 70 to move axially toward the upper nest 20, which in turn causes the lower nest 30 to also move toward the upper nest 20, gradually opening the umbrella.

As shown in Figures 8 and 9, the user continues to rotate the turntable 132 until the second screw 80 and the delay actuator 70 have completed all the opening strokes. At this time, the lower nest 30 is adjacent to the upper nest 20, so that the umbrella ribs 40 are opened. Umbrella-shaped, the multi-segment telescopic tube 112 of the umbrella handle group 110 can be further pulled down by the user and extends below the second screw 80, and the handle 111 can be held by the user.

When retracting the parachute, the turntable is rotated in the reverse direction, and the core gear drives the middle rod gear and the screw gear in the reverse direction, and finally the second screw and the delay actuator return to the position shown in Figure 4, which becomes the retracted state.

Please match Figures 2 and 9. In order to facilitate the collection of the umbrella surface, the umbrella can further include a bunch of umbrella cord 160 and a reel 170. The reel 170 is rotatably connected to the core gear 120 and rotates synchronously with the core gear 120. In the embodiment, the shaft 131 is connected to the core gear 120 through the reel 170, and the umbrella wire 160 is connected to a plurality of points on the umbrella cloth 50 in the center of the upper nest 20 and connected to the reel 170 after penetrating the upper nest 20. Both the lower nest 30 and the delay actuator 70 have thread holes 35 and 75 for passing the umbrella cord 160, so that when the core gear 120 rotates, the umbrella cord 160 can be constricted or released by the reel 170 to assist The rib 40 is folded or unfolded. In particular, because the umbrella of this embodiment is provided with the connecting strip 140, when the umbrella is first retracted, the delay actuator 70 will be driven downward and axially displaced, and the umbrella cord 160 will begin to be retracted, driving the umbrella cloth 50 and ribs 40 begin to fold, but the lower nest 30 remains still until the flexible connecting strip 140 reaches the maximum length; this design helps to make the umbrella cloth 50 and ribs 40 fold in advance and facilitate the collection of the umbrella Within 90 sets.

In summary, the present invention uses two sets of transmission systems to drive the lower nest and the umbrella cover to axially move in two different directions to achieve the purpose of linking the umbrella to open or retract the umbrella into the cover, and it also solves the inconvenient use of the existing umbrella cover. problem.
