When the umbrella is closed, the cover shrinks into the annular groove at hand, and when the umbrella is opened, the elastic umbrella opening structure slides upward along the middle rod, collides with the upper locro, and the position is limited under the upper locro. If there is a tube, there is an elastic vacancy above the position-restricted sill, and the elastic umbrella opening structure slides up, it will collide with the position-restricted sill, and the position-restricted sill will have some elasticity. Therefore, the impact can be mitigated.

It is a structural drawing of the umbrella opening and closing structure for preventing erroneous operation of the embodiment of this invention.

With reference to FIG. 1, the structure of the umbrella opening / closing structure for preventing erroneous operation, which is an embodiment of the present invention, will be described in detail.

As shown in FIG. 1, it has an elastic umbrella opening structure that wraps the middle rod 5 and the middle rod 5, respectively. This elastic umbrella opening structure has 12 medium wheels, 13 lower wheels, and 21 and 22 trousers. The trousers 21 and 22 include an upper trousers 21 connected to the middle wheel 12 and a trousers 22 connected to the lower wheel 13. There is an elastic position limiting piece 52 near the bottom of the center bar 5. The casing tube 22 has a hole 225 into which the position limiting piece 52 is inserted, the hole 225 penetrates the casing tube 22, and the hole 225 is provided with a button 226. In addition, the elastic umbrella opening structure includes an umbrella opening spring 3 which is a coil spring inside the upper tube 21 and the lower mantle tube 22.

When in use, if you hold the mantle tube 22 and slide it down along the middle rod 5, the mantle tube 21 and the middle wheel 12 move inside the lower wheel 22 and at the same time compress the umbrella opening spring 3 and lower it. The casing 22 puts pressure on the elastic position limiting piece 52 to allow the elastic position limiting piece 52 to enter the hole 225. At that time, the closing operation of the umbrella is completed. The umbrella cloth closes with the umbrella bone and covers the elastic umbrella opening structure. When opening the umbrella, put your hand in the umbrella cloth and press the button 226 on the mantle tube 22, the elastic position limiting piece 52 separates from the hole 225, and the umbrella opening spring 3 automatically opens the umbrella. Let it open.

In the optimum example of this embodiment, the front surface of the button 226 has a concave arc shape, and the surface of the button 226 is lower than the surface of the mantle tube 22. That is, the surface of the button 226 does not protrude from the surface of the trouser tube 22, and it is possible to avoid being pushed by the umbrella bone and the umbrella cloth.

As an optimum example of this embodiment, there is an arc-shaped transient groove 227 extending into the hole 225 at the bottom of the mantle tube 22. With the transient groove 227, when the umbrella is closed, the position limiting piece 52 can easily enter the hole 225, which saves physical strength. In FIG. 1, the transient groove 227 has an inclined surface in which the void gradually narrows upward.

As an optimum example of this embodiment, a hand 7 is installed at the bottom of the center rod 5. The cover trousers 8 are installed on the middle rod 5, and the length of the cover trousers 8 between the trousers 22 and the hand 7 is longer than the distance from the hand 7 to the position limiting piece 52, and the cover trousers 8 are installed. The tube 8 covers and can be opened the position limiting piece 52. The position limiting piece 52 is housed in the sliding groove 53 of the cover pipe 8. At hand 7, there is an annular groove 78 into which the cover pipe 8 is inserted, and between the annular groove 78 and the cover pipe 8, there is a return spring 87 which is a coil spring.

With the umbrella closed, the mantle tube 22 and the elastic position limiting piece 52 mesh with each other, and a part of the cover manure tube 8 enters the annular groove 78 at hand 7 to compress the repositioning spring 87. When the umbrella is opened, the mantle tube 22 separates from the position limiting piece 52 and slides upward, and the cover maneuver 8 slides upward by the repositioning spring 87 until it covers the position limiting piece 52. The elastic position limiting piece 52 protrudes to prevent collision with other articles.

As an optimum example of this embodiment, the cover pipe 8 has a sliding groove 53 into which the elastic position limiting piece 52 is inserted, the cover pipe 8 moves downward, and the cover pipe 8 holds the position limiting piece 52. When covering, the gliding groove 53 avoids pressure on the position limiting piece 52 and prevents it from losing elasticity. The bottom of the sliding groove 53 hits the position limiting piece 52 to prevent the cover pipe 8 from escaping from the annular groove 78.

As an optimum example of this embodiment, there is an upper wheel 11 at the tip of the middle rod 5. There is a position-limited casing 6 under the upper locro 11, and the position-limited casing 6 has an elastic vacant opening 61, and the elastic vacant opening 61 is installed so that the directions intersect with respect to the axis, and the umbrella is placed. When opening, the elastic umbrella opening structure slides upward along the middle rod 5 and hits the upper locro 11 at the tip, and while sliding upward, first contacts the position limiting casing 6 and the position limiting casing. The elastic vacant opening 61 of the tube 6 gives elasticity, and the elastic umbrella opening structure has a relaxing role.
