A first locking member (120, fig.1) and a second locking member 132 each include a latch 122, 1322 to be engaged with a hole 142 of the runner. A button 130 is connected to the base and the second locking member 132 is fixed to the button. A U-shaped member 134 is pivotably connected to the inside of the button 130 and two legs of the U-shaped member 134 can push the first locking member 120 inward to release the runner when opening the umbrella. During the first stage of collapsing, latch 122 is located in hole 142 and holds the runner in a partially closed state. The two legs of the U-shaped member are pivoted away from the two distal ends of the first locking member, so that even if the button is pressed at this stage, the umbrella does not open. When fully closed the latch 1322 is located in hole 142. This mechanism reduces the chance of accidents happening due to unintentional pressing of the button.
Description
TWO-STAGE COLLAPSING DEVICE FOR UMBRELLA
BACKGROUND OF THE INVENTION
(1)FIELD OF THE INVENTION
The present invention relates to a collapsing device, and more particularly, to a two-stage collapsing device for an umbrella and the device avoid from unexpected re-opening during operation.
(2) DESCRIPTION OF THE PRIOR ART
A conventional way to open an umbrella is to manually push the runner along the shaft of the umbrella upward until all the stretchers are expanded, and when collapsing the umbrella, the user presses a locking member inward to allow the runner to be moved downward to fotd the stretchers. An automatic umbrella adds springs to the stretchers and a button is installed on the handle so that when the user presses the button, the springs are released and the stretchers are expanded.
The opening is convenient for the users but when the user wants to collapse the automatic umbrella, the user has to pull the runner to overcome the force of the springs to fold the stretchers. This may not be convenient for some users who do not have sufficient force to overcome the force of the springs. In some situations, the user's hand may slip from the runner and the umbrella will open again at speed, which may injury or scare the user.
The present invention intends to provide a two-stage collapsing device for umbrella and which completely improve the shortcomings of the conventional umbrella collapsing device.
SUMMARY OF THE INVENTION
The present invention relates to a two-stage collapsing device which comprises a base having a passage defined therein, a first slot and a second slot are defined in an inner periphery of the passage. A first locking member is movably received in the first slot and includes a first latch protruding from a mediate portion thereof. A button is movably connected to the base and includes a second locking member, a U-shaped member and a trigger. The second locking member includes a second latch protruding from a mediate portion thereof and the second locking member is fixed to an inside of the button and movably received in the second slot. The U-shaped member is pivotably connected to the inside of the button and two legs of the U-shaped member are located corresponding to two distal ends of the first locking member. The trigger is pivotably connected to the inside of the button.
The primary object of the present invention is to provide a two-stage collapsing device for umbrella, wherein the runner is held and* cannot be released even when the button is unintentionally presses. The runner is then ensured to be locked after the second step of collapsing is completed.
Another object of the present invention is to provide a two-stage collapsing device for umbrella, wherein the umbrella does not open suddenly during collapsing either by pushing the button or releasing the runner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figs. 1 and 2A, the two-stage collapsing device 100 of the present invention comprises a base 110 which includes an opening 116 in a top thereof and a notch 118 is defined in an inner periphery of the opening 116. A passage 112 is defined in the base 110, and a first slot 114A and a second slot 114B are defined in an inner periphery of the passage 112. A bolt 150 is used to fix the base 110 in a case 160 of the handle of the umbrella as shown in Fig. 2A.
A first locking member 120 is movably received in the first slot 114A and a spring is located between the first locking member 120 and the inside of the base 110. A first latch 122 protrudes from a mediate portion of the first locking member 120. The first locking member 120 is a U-shaped member and the first latch 122 includes an inclined surface.
A button 130 is movably connected to the base 110 and can be accessed from outside of the case 160 of the handle. The button includes a second locking member 132, a U-shaped member 134 and a trigger 136. The second locking member 132 includes a second latch 1322 protruding from a mediate portion thereof and the second latch 1322 includes an inclined surface. The second locking member 132 is fixed to an inside of the button 130 and movably received in the second slot 114B with a spring located between the second locking member 132 and the inside of the base 110. The U-shaped member 134 is pivotably connected to the inside of the button 130 and two legs of the U-shaped member 134 are located corresponding to two distal ends of the first locking member 120. The trigger 136 is pivotably connected to the inside of the button 130.
A runner 140 is a hollow and cylindrical member and includes a hole 142 defined in a wall thereof, a protrusion 144 and two side wings 146 protrude from an outside of the rubber 140. The two side wings 146 are located symmetrically about an axis of the hole 142 and the protrusion 144 is located above the hole 142.
There are a first stage of collapsing and a second stage collapsing of step when the runner 140 moves toward the base 110 and is
S
engaged with the base 110. When the user pulls the runner 140 downward as shown in Fig. 2A and the runner 140 continues to move to insert the opening 116 of the base 110, the protrusion 144 is movably engaged with the notch 118.
During the first stage of collapsing as shown in Fig. 2B, the first latch 122 of the first locking member 120 is engaged with the hole 142 of the runner 140, the two side wings 146 of the runner 140 push the two legs of the U-shaped member 134 downward and the trigger 136 is pivoted downward during the first stage of collapsing. It is noted that because the two legs of the U-shaped member 134 downward so that even if the button 130 is unexpectedly pressed, the first locking member does not activated by the two legs of the U-shaped member 134, so that the umbrella does not open.
