Abstract

The umbrella of the present invention is designed so that the spreading and folding are automatic, and one end is hinged to a certain portion of the support (6), and the other end is disposed on the spreading (5) hinged to the second notch (9). Umbrella is designed to expand the umbrella by pushing the second notch 9 in the direction of the first notch 1, and the extension spring 10 is a spring that pushes the second notch 9 in the direction of the first notch 1. The outer tube 16 is mounted on the outer periphery of the compression tube 12 and the lower end of the compression tube 12 is fixed inside the handle 23 to compress the expansion spring 10. And another device was added to enable the unfolding and folding with one button (21).

Holding the handle 23 to open the umbrella, pressing the head of the umbrella against the ground, the spreading spring 10 is compressed, the handle 23 and the outer tube 16 is returned.

Then, pressing the button 21, the third lock haechuchu 15 pushes out the third lock 19, the outer pipe (3, 16) and pushed out the compressed spring (10) at this time relaxes the umbrella In order to fold the umbrella, press the button again to expand the folding spring (8), which was expanded when it was unfolded, and the umbrella was folded.

The umbrella of the present invention is designed to compensate for the inconvenience caused by the automatic umbrella used in the market because the folding state is not automatically, so that the spreading and folding are all automatic.

Hereinafter will be described in detail with reference to the accompanying drawings the structure, operating state and effects of the subject innovation umbrella.

At the top of the umbrella of the present invention, the first notch 1 hinges the umbrella flesh 4, and at the bottom side thereof, there is an unfolding state sensor 2.

As shown in the drawing, the supporter 6 is hinged on the umbrella 4 and the spreader 5 is hinged on the supporter 6.

The inner tube (3) fixed inside the first notch (1) is inserted into the inside of the handle (23) down, but the various parts of the inner tube (3) are perforated and opened so that the first lock (11) second The lock 14 and the third lock 19 are provided so that they can be sunk by the elasticity of the spring from the inside and the outside.

The spring compression tube 12 slides up and down on the outer periphery of the inner tube 3 at the lower end of the first notch 1, and the spreading spring 10 is mounted on the outer periphery of the compression tube 12.

On the outer circumference of the upper end of the spring compression pipe 12, the second notch 9 hinges the spreading bar 5, and at a certain portion of the spreading bar 5, the folding spring 8 is hinged. The other end of 8) is hinged to a part of the support (6).

The third notch 18, which is hinged to the lower end of the support bar 6, is hinged to the one side of the third lock 19 to move up and down from the outer periphery of the inner tubes 3 and 16 and the extension spring 10. It is supposed to slide.

At the lower end of the spring compression tube 12 of the inner tube 3, the outer tube 16 has an opening 20 with its lower end fixed inside the handle 23.

Inside the lower handle 23 of the umbrella there is a return spring 22 and the upper side has a button 21.

Inside the inner tube 3, there is a first lock 11 and a second lock 14, and the first lock release weight 13 and the third lock 19 capable of releasing the first lock 11 are provided. There is a third lock release weight 15 that can be released, and below that there is a triangular weight 17 so as to be able to operate with one button 21 at the time of opening and closing.

The operating state of the structure umbrella is as follows.

1 is a state in which the umbrella is folded, in this state holding the handle 23, the head of the umbrella touches the ground and then press the top of the outer tube 16 inserted into the handle 23 is the spring compression tube 12 And pushes the lower end of the compression tube 12 and the extension spring 10 of the outer circumference of the compression tube 12 is compressed, and the first lock 11 hinged inside the inner tube 3 protrudes out of the opening of the inner tube 3. And the lower end of the spring compression tube 12 is extended to prevent the unfolding spring 10 is relaxed, as shown in the figure of FIG.

Then grab the handle 23 and lift the umbrella, the handle return spring 22, which has been compressed, is relaxed and the handle 23 is pushed out. It becomes 3 degrees.

When the button 21 is pressed in this state, the button 1 presses the upper slope of the upper leg of the triangular weight 17, and when the triangular weight 17 goes down by sliding friction, the third lock release weight connected to the upper portion of the triangular weight 17 is pressed. (15) comes down and pushes the third lock (19) out at this time, the unfolding spring (10) compressed in the outer circumference of the spring compression tube 12 is relaxed, the second notch (9) toward the first notch (1) When pushed, the spreading bar (5) hinged to the second notch (9) pulls the hinge point with the support bar (6) and the support bar (6) pushes the hinge point with the umbrella bar (4). (18) goes up and the umbrella unfolds. When the umbrella is fully unfolded, when the upper end of the second notch 9 pushes the unfolded state detection sensor 2 protruding from the bottom of the first notch 1, it is connected with the detection sensor 2 and installed inside the inner tube 3. The unfolded unfolding spring 7 is compressed and becomes as shown in FIG.

Then, when the button 21 is released, the button 21 is pushed out and at the same time, the spreading detection spring 7 is relaxed and the triangular weight 17 at the bottom of the inner tube 3 is raised to the first lock haechuchu 13. The first lock release weight 13 comes into contact with the lower end of the first lock 11 by pushing upwards.

At this time, if the button 21 is pressed again, the button 21 pushes up the lower oblique surface of the triangular weight 17 so that the first lock release weight 13 slides upward when the first lock 11 is pushed upward. One lock 11 enters the inner leg of the inner tube 3.

This is the spring compression tube 12 is in a state that can be freely sliding in the outer circumference of the inner tube (3) at this time, the folding spring (8), which is hinged to the spreading bar (5) and the support bar (6) when the umbrella is expanded This contraction is pulled the hinge point of the spreading bar (5) and the support bar (6), the umbrella is folded, the spring compression tube 12 and the unfolding spring (10) also comes down as shown in Figure 1.
