The temporary fixing part 140 maintains the compressed state when the folding spring 120 is compressed, and the compressed state is released when the spring receiving part 110 moves to the upper cap 10 by the restoring force of the expanding spring 130. It is possible.

The reason for temporarily fixing the folding spring 120 in the temporary fixing part 140 is that, when the folding spring 120 is not fixed to the temporary fixing part 140, the restoring force of the expanding spring 130 when the automatic umbrella 1 is unfolded. This is because the restoring force of the and folding springs 120 acts at the same time, so the unfolding operation cannot be performed properly.

On the other hand, the temporary fixing unit 140 automatically releases the compression state of the folding spring 120 after the automatic umbrella (1) is fully unfolded, in which case the compression state of the folding spring (120) A separate additional action is needed to unlock it.

Therefore, by providing the temporary fixing unit 140, the unfoldable and foldable automatic umbrella 1 can be automatically unfolded and folded as well as the folding process can be completed by pressing a button without additional user action.

Here, the temporary fixing part 140 may be provided in various ways, for example, the engaging projection 141 provided along the edge of the heavy latch 90 and the spring receiving portion 110 is formed extending from the folding spring When the compression of the 120, the locking projection 141 is held by the engaging portion 143 and protruding along the edge of the upper cap 10 to release the locking portion 143 when the spring receiving portion 110 approaches. The release protrusion 145 may be provided.

The release protrusion 145 is provided to protrude along the edge of the upper cap 10, as shown in FIG.

As illustrated in FIG. 1, the release protrusion 145 may be provided by forming a step and forming a gentle inclined surface toward the handle part 35.

Here, the protruding height of the release protrusion 145 is provided so that the locking protrusion 141 may be separated from the locking portion 143 when the locking portion 143 is slid open.

In the above case, when the locking projection 141 is coupled to the locking portion 143 and moved toward the upper cap 10, the locking portion 143 protruding a predetermined distance to the upper end of the heavy latch 90 is released. Slip on the 145 has the advantage that the locking projection 141 is easily separated.

The release protrusion 145 may be provided corresponding to the number of the locking protrusion 141 and the locking portion 143 is provided.

Therefore, the temporary fixing part 140, as shown in Figure 4, when the automatic umbrella (1) that is unfoldable and foldable by the elastic force of the unfolding spring 130 is unfolded, the release projection provided on the lower end of the upper cap 10 The extension blade 115 is slid and opened by 145 to release the locking protrusion 141 from the locking portion 143.

Here, even when the temporary fixing part 140 is released, the folding spring 120 maintains a compressed state because the first connection member 160 and the second connection member 170, which will be described later, balance one-to-one forces with each other.

Hereinafter, referring to FIGS. 2 and 3, the coupling relationship between the above-described heavy clasp 90, lower clasp 100, spring accommodating part 110, unfolding spring 130, and folding spring 120 will be described. As follows.

As shown in FIG. 5, the protrusion 210 has a step in the direction in which the upper and lower rods 20 and 30 are spaced apart from each other, and a gentle inclined surface is formed in the opposite direction thereof.

When the user tries to unfold the upper and lower arms 20 of the unfoldable and foldable automatic umbrella 1 against the lower bar 30 by force, as shown in FIG. 5A, the step is applied to the upper bar 20. The third through hole 23 is provided to be caught and not spread.

On the other hand, in the case of pressurizing the unfoldable and foldable automatic umbrella 1, as shown in Figure 5 (b), the fourth through hole 39 provided in the lower rod 30 is the expansion prevention part 200 The gentle inclined surface is pressed, and the protrusion 210 is inserted into the core rod 40 while being separated from the third through hole 23.

Therefore, the spread prevention unit 200 does not know how to use the unfoldable and foldable automatic umbrella (1) without pressing the upper rod 20 from the lower rod 30 without compressing the unfoldable and foldable automatic umbrella ( 1) to prevent damage.

When the automatic umbrella according to the present invention by this will be described as follows.

1 is a cross-sectional view showing a state before compression of the automatic umbrella 1 according to the present invention.

First, the lower rod 30 is pressed against the upper rod 20 and the core rod 40 in order to compress the unfolding spring 130 and the folded spring 120.

As the lower rod 30 rises, the second connection member 170 fixed to the second through hole 31 is drawn between the upper rod 20 and the lower rod 30 as shown in FIG. The pulley 150 pushes up the spring accommodating part 110 while being pressed upward.

On the other hand, because the heavy clasp 90 and the lower clasp 100 is restricted by the extension 60 and the lower support 70, the heavy clasp 90 and the lower clasp 100 is fixed in position As the spring receiving portion 110 approaches in the state, the expanding spring 130 and the folding spring 120 are pressurized and compressed.

When the spring accommodating part 110 is moved by a predetermined distance and the compression is completed, the locking projection 141 provided in the temporary fixing part 140 is coupled to the locking part 143 and the folding spring 120 is temporarily fixed in the compressed state. .

At the same time, the expansion fixing hole 101 in the handle part 35 is fixed to the expansion button unit 180, the folding fixing hole 45 is locked to the folding button unit 190, the compression step is completed. .

Here, the lower rod 30 is pressed and the moving distance is the distance of the lower clasp 100 is separated from the spring receiving portion 110 and the second connecting member 170 of the cut portion 43 is moved in the core rod 40 Matches the length

Therefore, in the compressed state, as shown in FIG. 3, the folding spring 120 maintains the pressurized state by the temporary fixing part 140, and the expanding spring 130 is pressed by the expanding fixing hole 101. Maintain state.

In addition, the first connection member 160 and the second connection member 170 are tensioned to be in a compressed state in which one-to-one equilibrium is maintained.

Next, the operation of unfolding the automatic umbrella (1) is as follows.

First, when the release button hole 180 is released by pressing the spread button unit 180, the lower clasp 100 restricting the restoring force of the spread spring 130 is lowered from the lower rod 30 or the handle portion 35). As it is released, the restoring force of the spreading spring 130 acts.

Unfolding spring 130 is to push up the lower clasp 100, thereby extending the length of the lower support bar (70) while at the same time narrowing the gap between the umbrella meat is unfolded.

On the other hand, the pulley 150 is fixed to the end of the upper rod 20 by a step with the upper rod 20, so that it can no longer rise to perform a fixed pulley function.

However, since the heavy clasp 90 is pushed by the lower clasp 100 and continuously raised, the second connecting member 170 is relatively lower as the pulley 150 is pulled out from the inside of the upper rod 20 to the axis. It serves to take out 30 from the upper rod 20.

While the heavy clasp 90 and the spring receptacle 110 are raised toward the upper cap 10, the folding spring 120 is still being pressed by the temporary fixing part 140.

However, in the state where the restoration of the unfolding spring 130 is completed and the ascending latch 90 is completed toward the upper cap 10, as shown in FIG. 4, the catching portion 143 is a release protrusion 145. Slid by) and the locking projection 141 is released.

At this time, the sliding pulley 150 is inserted into the lower rod 30 is fixed close to the lower end of the upper rod 20 and the first connection member 160 and the second connection member 170 to maintain a one-to-one equilibrium.

Therefore, as shown in FIG. 4, the folding spring 120 maintains a pressurized state and the umbrella is in an unfolded state.

Finally, in order to fold the automatic umbrella (1) releases the folded fixing hole 45 provided in the core rod 40 in the folded button unit 190.

As described above, the first connection member 160 and the second connection member 170 are kept in balance in the tensioned state by the folding spring 120.

However, when pressing the folded button unit 180 to release the core 40 from the lower rod 30, when the core 40 is lifted from the lower rod 30 by the tension of the first connecting member 160, The effective length of the first connecting member 160 is momentarily increased, so that the balance between the first connecting member 160 and the second connecting member 170 is broken.

Therefore, while the folded spring 120 is restored, the spring accommodating part 110 and the lower clasp 100 are sequentially pushed downward, and are connected by the connecting structure of the stretch bar 60 and the lower support arm 70. Clasp 90 is pushed down to the bottom of the upper rod (20) together.

Thereafter, the first connecting member 160 is pulled out of the upper rod 20 as the heavy clasp 90 descends, and the core rod 40 and the lower rod 30 are drawn into the upper rod 20. Will be.
