The present invention relates to a tech field o a reversely folded umbrella.
Some companies have developed the umbrellas able to be reversely folded and closed, such as the “a kind of automatically out-turned umbrella”, Patent No. CN205337924U announced in the Mainland China. Its advantages, include the simple structure, convenient way of opening, acting force ensuring the umbrella runner's upward going produced through the umbrella runner pulling by the first elastic piece, nice appearance, strong practicability and good safety. However, it is discovered after use that it still has the following problems:
1. The umbrella is opened such that an acting force ensuring; the umbrella runner's upward going is produced through the second mounting groove pulling by the first elastic piece. Therefore, when the automatically out-turned umbrella is in the closed state, the, automatically out-turned umbrella can only be fixed in the closed state by engaging the clamping piece on the umbrella shaft together with the umbrella runner. However, because the first elastic piece has a certain pretension force, the umbrella runner would have the problem of popping open in the case of casual umbrella shaking by the user or accidental umbrella collision with some object because of the pretension force of the first elastic piece. Moreover, although the umbrella runner fixing by way of clamping piece is easy, the clamping piece is often not positioned into the stop hole on umbrella shaft during, assembly and therefore unable to be clamped within the stop hole, thus producing quality defects; and, the clamping piece can only be clamped within the stop hole on umbrella shaft by continuous manual adjustment, resulting in long assembly man-hours and not up to the production effectiveness.
2. Since the umbrella frame of the automatically out-turned umbrella is fixed by the umbrella runner, in the case of strong wind or umbrella frame end collision with some foreign object or person, the force produced by the collision and wind resistance cannot be offset or abated. Therefore, the umbrella frame is liable to deformation and damage with its service life reduced; and it may even bump into other people and the umbrella frame end may have the danger of stabbing and hurting other people.
In view of the above-mentioned disadvantages, the issue to be solved in this case is how to develop a kind of hand-push rotating umbrella where a stable closed state of umbrella can be achieved without providing the engagement structure and the umbrella canopy can rotate when the umbrella is in the opened state to avoid stabbing and hurting other people.
The purpose of the present invention is to provide a stable umbrella-recovery state without disposing a snap-fit structure, and the umbrella-surface can be rotated to avoid injuring another person's hand-pushing rotary umbrella in an open umbrella state.

In other words, in the case of closing the umbrella, the umbrella closing state can be achieved without providing, the engagement structure and only by pulling down the moveable runner vertically to restore the extension spring back to the tension-free state. In addition, the man-hours for the engagement structure positioning can be saved during production and assembly because no engagement structure is required, which makes the processing and assembly faster and more convenient and is up to the economic effectiveness. Therefore, compared with the previous cases, it is characteristic of convenient operation, low cost and simpler structure.
Through the collocation application of the upper runner and moveable runner, when the user opens up the umbrella in the case of strong wind or umbrella rib collision with some foreign object or person, the umbrella canopy would rotate to offset the impact force caused by the wind resistance or collision. In addition to avoiding the umbrella canopy deformation and damage, it also can avoid injury to the person holding or colliding with the umbrella so as to improve the umbrella use safety.
There are two embodiments of the present invention. First, the first embodiment is described. Referring to

Through the collocation application of the upper runner 3 and moveable runner 4, when the user opens up the umbrella in the case of strong wind or umbrella rib collision with some foreign object or person, the umbrella canopy would rotate to offset the impact force caused by the wind resistance or collision. In addition to avoiding the umbrella canopy deformation and damage, it also can avoid injury to the person holding or colliding with the umbrella so as to improve the umbrella use safety and practicability.
Then, the rotating runner seat 33 can be assembled at the top of the umbrella shaft 1 through the connecting piece 32 and the connecting piece 32 is fixed at the bottom of the rotating runner seat 33 by the first inserting pin 34. Therefore, even when the umbrella canopy encounters a strong wind or in the case of umbrella rib collision with some foreign object or person, the upper rib supporting rods 6 can drive the rotating runner seat 33 and connecting piece 32 to rotate relative to the umbrella shaft 1. Thus, the umbrella shaft 1 and upper rib supporting rods 6 would not be damaged under the influence of the twisting force and the service life can be extended.
Moreover, through the application of the second inserting pin 35, the coupling piece 31 can be fixed into the umbrella shaft 1 to avoid the falling of the coupling piece 31.
Referring to
Through the collocation application of the protruding section 321 and the left and right curved grooves of 3111 and 3121, the connecting piece 32 can rotate smoothly driven by the rotating runner seat 33 without friction with the inner wall of the left and right casings of 311 and 312 to produce resistance.
Then, because the width of the positioning body 322 is larger than the top diameter of the coupling piece 31, the positioning body 322 can be positioned at the top of the coupling piece 31 for the insertion of the bottom of the rotating runner seat 33.
Moreover, through the collocation application of the clamping edge 3221 and retaining piece 331, it can prevent the rotating runner seat 33 from being inserted too much into the connecting piece 32 to cause the rotation impossible.
Referring to
A cushion cover 36 is provided at the top of the upper runner 3; thereby, it can clamp and fix the edge of the outer umbrella cloth C tightly so that there are no cracks at the end edge of the hand-push rotating umbrella 100 to avoid rainwater seepage or loose threads; and it also has the buffering and anti-slip function in application to reduce the damage to the user's hand caused by the ground feedback force and the occurrence of slip.
As shown in
Moreover, the diameter of the middle runner 5 is smaller than the diameter of the moveable runner 4; thereby, when the lower rib supporting rods 8 and, supporting ribs A are closed, there are no pressure and tightness problems between them at all and the hand-push rotating umbrella 100 becomes more flexible and smoother in the closing and opening up applications.
