A cap 12 is provided on the upper end of the umbrella stand 10 and a runner 15 is provided which slides up and down along the umbrella stand 10.

The umbrella body 14 is connected to the cap 12 and the runner 15 and radially spreads around the umbrella body 10 and the umbrella body 14 is covered with a covering material (not shown).

The umbrella body 14 is provided with an umbrella body spring 14a so that the umbrella body is stretched when the umbrella is folded. When the umbrella is folded, the umbrella body 14 is stretched by the contractive force.

It is needless to say that the folding and unfolding structure of the umbrella body 14 may be variously applied in addition to the above-described examples.

The handle 40 is provided at the lower end of the umbrella stand 10, as shown in Fig.

The wire roll (50) is provided inside the handle (40).

The first wire (61) is fixed at one end to the wire roll (50) and the other end is fixed to the cap (12).

Since the first wire 61 is connected to the cap 12, when the wire roll 50 is rotated and wound by driving the motor 71, the cap 12 is pulled toward the handle 40 Let the umbrella stand (10) shrink (the multi-stage umbrella gets in each other) and collapse the umbrella stand.

The first wire 61 may be provided to shrink only the umbrella band 10 but may be connected to the runner 15 via the cap 12 or connected to the cap 12 via the runner 15 first The cap 12 and the runner 15 can be pulled toward the handle 40 simultaneously with only one first wire 61 so that the umbrella stand 10 as well as the umbrella stand 14 can be folded at the same time.

Alternatively, a second wire, one end of which is fixed to the wire roll 50 and the other end, which is fixed to the runner 15, may be additionally provided.

5, the wire roll 50 has a radius of rotation corresponding to the movement distance of the cap 12 at the folding of the umbrella stand 10, The first rotating part 51 and the second rotating part 52 having the turning radius corresponding to the moving distance of the runner 15 when folding the umbrella stand 10 and the second wire being wound.

6, since the movement distances of the cap 12 and the runner 15 are different from each other when the umbrella is folded, the first rotation part 51 having the rotation radius corresponding to each distance, The runner 15 and the cap 12 can be moved in accordance with the respective moving distances even when the wire roll 50 rotates at the same rotational speed.

For example, when the movement distance of the runner 15 is 1/2 of the movement distance of the cap 12, the circumference of the first rotation part 51 is set to have two lengths than the circumference of the second rotation part 52 .

The motor 71 generates rotational driving force for rotating the wire roll 50.

The motor 71 may be of various types known in the art without limitation, but the driving force must be greater than a force capable of contracting the unfolding spring 17 described later.

The power supply unit 73 supplies power to the motor 71.

The power supply unit 73 may be provided in a detachable type that can be replaced, or in a form that can be charged, if necessary.

Alternatively, it may further include a charge amount display unit for displaying a charge amount of the power source unit 73 or for informing a state of discharge.

The tilt sensor 81 generates a folding signal when the angle between the umbrella bed 10 and the ground is within a folding angle for folding the umbrella.

For example, as shown in FIG. 7, when the cap 12 is positioned closer to the ground than the handle 40, (?).

The drive switch 75 is provided to drive the motor 71.

The drive switch 75 is provided on one side of the handle 40 and may be provided separately from the button 30, but may be provided as one.

The control unit 79 controls the motor 71 to operate only when the drive switch 75 is operated in a state in which the folding signal is applied.

This is because the driving of the motor 71 is intended to be driven only in a state in which the umbrella is about to be folded. In the state in which the umbrella is used, that is, when the umbrella stand 10 is near vertical to the ground, no folding signal is generated. It is determined that the user intends to fold the umbrella even if the driver 75 operates, so that the motor 71 is not driven.

Therefore, according to the present invention, the umbrella can be automatically folded by using the driving force of the motor, so that the umbrella can be folded without a user's force, and the umbrella is folded only when the operation of the driving switch and the folding signal occur simultaneously , It is possible to prevent the umbrella from folding due to a malfunction in use, thereby further improving the operation reliability according to use.

On the other hand, in the multi-stage automatic folding umbrella 1 according to the present invention, the operation of unfolding the umbrella can also be provided to be automatically opened by the unfolding spring 17. [

For example, as shown in FIG. 3, the latch part 40 is provided at one side of the handle part 40, And a latching groove 23 provided at one side of the runner 15 facing the handle 40 to receive a latch which is drawn out to the outside of the umbrella stand 10.

3, the button 30 is provided to be pulled out from the inside and outside of the handle 40, and the latch 21 is integrally connected to the button 30, The presser foot 21 is also pulled into the umbrella frame 10 and released from the catch groove 23 so that the runner 15 can move freely.

6, the spread spring 17 is provided inside the umbrella stand 10 so that the spread spring 17 is in a contracted state (when the umbrella stand 10 is folded) The movement of the runner 15 is limited and the movement of the cap 12 fixed by the runner 15 and the umbrella 14 is also limited) The cap 12 is allowed to move together with the runner 15 so that the umbrella stand 10 is unfolded by pushing the cap 12 by the restoring force of the unfolding spring 17. [

On the other hand, in the umbrella shell 14, when the umbrella is folded, the distance between the runner 15 and the cap 12 is distanced so that the umbrella shell spring 14a is in a tensioned state. The umbrella resilient spring 14a is retracted to unfold the umbrella flesh 14.

 Therefore, according to the multi-stage automatic folding umbrella according to the present invention, not only the folding operation of the umbrella but also the operation of extending the umbrella can be automatically deployed by the expanding spring, thereby further enhancing the user convenience.

Meanwhile, in the process of automatically folding the umbrella using the motor 71, the controller 79 may drive the motor 71 only while the folding signal and the operation of the drive switch 75 are continuously maintained , When the initial folding signal and the operation of the drive switch 75 are satisfied, the drive of the motor 71 can be started and the driven state can be maintained.

In the latter case, it is convenient that the user does not have to hold the drive switch 75 in the process of folding the umbrella.

In both of the above-described embodiments, when the umbrella is completely folded, the control unit 79 can automatically stop the driving of the motor 71.

The control unit 79 further includes a latch sensor 83 for generating a latch signal when the latch 21 is accommodated in the latch groove 23, The driving of the motor 71 can be stopped.

Therefore, the user can automatically stop the motor 71 when the umbrella is folded without the user performing any other operation for stopping the motor 71, thereby further enhancing user convenience.

1, a speed reducer unit 90 provided between the motor 71 and the wire roll 50 for transmitting the rotational force of the motor 71 to the wire roll 50 may be further included.

The reduction gear unit 90 performs a function of reducing or accelerating the rotation speed of the motor 71 corresponding to the rotation speed of the wire roll 50. For example, as shown in FIG. 1, A second gear 92, and a third gear 93, as shown in FIG.

The reduction gear unit 90 is provided so as to be rotatable only in one direction, for example, so that the driving of the motor 71 is stopped by a malfunction in the process of winding the first wire 61 and the second wire 62, Or the rotation of the motor 71 causes the wire roll 50 to rotate reversely to prevent the wires 61 and 62 from being unwound.

The gear releasing section 110 is provided to release the wire roll 50 from the reduction gear section 90 when the latch 21 is released from the latch groove 23.

This is to prevent the reverse rotation of the motor 71 from being applied to the motor 71 even if the reduction gear unit 90 is capable of rotating in only one direction or the reduction gear unit 90 is capable of rotating in both directions as described above .

The gear releasing portion 110 includes a moving rod 101 for pushing the first gear 91 into the wire roll 50 and releasing the first gear 91 from the second gear 92 when the button 30 is operated, And a restoring unit 105 that restores the first gear 91 to its original position when the button 30 is released.

3, when the button 30 is pressed in the folded state of the umbrella, the latch 21 connected by the moving rod 101 is drawn into the umbrella frame 10, The moving rod 101 pushes the first gear 91 into the wire roll 50 and the first gear 91 is released from the second gear 92 so that the wire roll 50 It is possible to freely rotate in reverse.

Thereafter, when the pushing operation of the button 30 is released, the contracted restoring portion 105 pushes up the first gear 91, and the button 30 also receives the restoring force through the moving rod 101, Return.
