Description

Multi-stage automatic umbrella {MULTI-FOLDING AUTOMATIC UMBRELLA}

The present invention proposes a structure that reduces the force required for driving in a multi-stage automatic umbrella using a driving force such as a motor or magnetic force, so that when a driving motor is used, a driving motor of low torque can be used, and a driving motor of the same torque can be used. It relates to a multi-stage automatic umbrella that can reduce battery consumption.

Recently, for the purpose of improving user convenience and product differentiation, various types of multi-stage automatic umbrellas that can be folded or unfolded without human effort have been proposed.

As an example, the multi-stage automatic umbrella uses a method of installing a connection member such as a thread or a plurality of gear trains inside the umbrella stand and installing a drive motor for driving it in the handle portion to control the operation of the drive motor by a button. .

However, in order to fold or unfold the entire umbrella with the drive motor, in addition to the force required to operate the above connection member or gear train, a force to compress (or tension) the unfolding spring (or folding spring) is used, so a drive motor having a large torque is used. There is a problem in that the manufacturing cost increases, and the greater the torque, the greater the battery consumption, so the user has to frequently replace or charge the battery.

Furthermore, when the aforementioned multi-stage automatic umbrella does not work because the battery is discharged during use, the umbrella itself cannot be folded or unfolded, so there is a problem in that it cannot function as the umbrella itself.

Finally, as the first wire 71 fixed to the middle rod cap 121 is drawn into the upper rod 21 as the middle rod 23 is withdrawn, the runner 30 is pulled up to the upper portion of the upper rod 21, The umbrella is unfolded by the spreading ribs 15 fixed to the runner 30 . (See Fig. 2)

Conversely, when folding the umbrella, since the folding spring provided between the spreading rib 15 and the shank 13 is in a state in which the umbrella is stretched and stored to store the restoring force, it is folded when the rotation fixing of the winding part 80 is released. As the runner 30 is pushed down by the restoring force of the spring, the first wire 71 is drawn out of the upper bar 21, and the middle bar 23 moves to the upper bar 21 and the lower bar 22 in a continuous operation. ) is drawn into the middle rod 23 , and when the lower rod 22 is drawn into the middle rod 23 , the moving rod 51 is pushed downwards away from the upper fixing part 60 by the push rod 25 . Accordingly, the gap between the upper fixing part 60 and the moving rod 51 is widened, and the second wire 72 wound around the winding part 80 is released.

As shown in FIG. 1, the upper rod 21, the middle rod 23 and the lower rod 22 are provided in a hollow cylindrical shape with different inner diameters, and the lower rod 22 is drawn out and inserted into the middle rod 23, The middle rod 23 is provided so as to be able to be drawn in and out of the inside of the upper rod 21 .

The runner 30 has an inner shape corresponding to the outer shape of the upper rod 21 and is fitted to the outside of the upper rod 21 so as to be movable up and down along the upper rod 21 .

A plurality of spreading teeth 15 are radially coupled to the runner 30 along the circumference. As it moves downward along (30), the umbrella is pulled down and the umbrella is folded.

On the other hand, as shown in FIG. 2 , when the runner 30 rises toward the Sangbong cap 11 side, the spreading rib 15 pushes up the umbrella rib 13 to unfold the umbrella.

At this time, a folding spring 16 is provided between the unfolding rib 15 and the umbrella rib 13. The folding spring 16 stores the restoring force when the umbrella is unfolded, and then the driving force (or fixing force) in the winding unit 80. ) is released, so that the umbrella flesh 13 is folded by the restoring force.

As shown in FIG. 1 , the upper fixing part 60 is fixed inside the upper side of the lower rod 22 , and a plurality of upper pulleys 53 are installed in the upper fixing part 60 .

One end of the first wire 71 to be described later is fixed to one side of the runner 30 .

The first wire 71 is provided between the runner 30 and the middle bar 23 to interlock the vertical movement of the runner 30 and the withdrawing and withdrawing of the middle bar 23 with respect to the upper bar 21 .

That is, the first wire 71 inserts the middle rod 23 into the upper rod 21 when the runner 30 goes down to the lower part of the upper rod 21, and on the contrary, when the middle rod 23 is withdrawn from the upper rod 21, the runner (30) is raised to the upper part of the sangbong (21).

The first wire 71 is, for example, as shown in FIG. 1, one end is fixed to the runner 30, and the other end is via the Sangbon pulley 191 provided in the Sangbong cap 11 of the Sangbong 21. After being drawn into the upper rod 21, it may be fixed to the middle rod cap 121 of the middle rod 23.

The second wire 72 is provided over the winding portion 80, the upper fixing portion 60, and the moving rod 51 and interlocks the vertical movement of the movable rod 51 according to the winding or unwinding of the winding portion 80. .

That is, as shown in FIGS. 1 and 2, the second wire 72 raises the moving rod 51 to the upper fixing part 60 side when the second wire 72 is wound in the winding part 80, When the moving rod 51 is moved downward by being spaced apart from the upper fixing part 60 by the push bar 25 , the second wire 72 wound around the winding part 80 is released.

To this end, the second wire 72 is, for example, as shown in FIG. 1 , one end is fixed to the winding portion 80 , and the other end is respectively to the upper fixing portion 60 and the moving rod 51 . It may be fixed to any one of the upper fixing part 60 or the moving rod 51 via the provided plurality of upper pulleys 53 .

Alternatively, the third wire 73 is, as shown in FIG. 2, after the other end is drawn into the lower rod 22, through the upper pulley 43 provided on the moving rod 51 to the lower rod cap 122. may be fixed.

The upper fixing part 60 is fixed inside the upper side of the lower rod 22 facing the handle part 17 .

The upper fixing part 60 is fixed in its position, unlike the moving rod 51 to be described later, and approaches the moving rod 51 upward or downward by the second wire 72 connected together with the moving rod 51 . to separate

That is, referring to FIG. 1 , the second wire 72 passes through the upper pulley 53 of the moving rod 51 and again through the upper pulley 53 of the upper fixing part 60 , the moving rod 51 . When the second wire 72 is wound by the winding part 80 , as shown in FIG. 2 , the lower moving rod 60 approaches the upper fixing part 60 side.

The second wire 72 is provided over the winding portion 80, the upper fixing portion 60 and the moving rod 51, and interlocks the winding or unwinding of the winding portion 80 and the vertical movement of the movable rod 51. .

Here, a plurality of upper pulleys 53 are installed between the moving rod 51 and the upper fixing part 60 , respectively, and the number of the upper pulleys 53 can be adjusted in response to the driving force of the take-up part 80 .

That is, when the number of the upper pulleys 53 increases so that the second wire 72 passes through the upper pulleys 53 of that large number, for example, as in FIGS. 1 and 2 , each of the two upper pulleys When 53 is installed and the second wire 72 passes between the moving rod 51 and the upper fixed part 60 four times, the winding part 80 is 4 times compared to the moving distance of the moving rod 51 . The length of the second wire 72 should be wound.

Therefore, when applying the principle of work, if it takes the same work (W) to fold the umbrella, the length (S) of winding the second wire 72 increases four times, so that the second wire 72 The driving force required to wind the motor is reduced by 1/4.

Therefore, if the number of upper pulleys 53 is increased to increase the winding length of the second wire 72 by that much, it is possible to fold the umbrella with less driving force. , there is an advantage that battery consumption can be reduced when a driving motor of the same torque is used.

Here, if the number of the upper pulleys 53 is increased too much to lower the driving force, the time required to wind the second wire 72 may be long. Conversely, if the number of the upper pulleys 53 is too small, the driving force reduction effect is Since it cannot be exerted, it is preferable to select an appropriate number of the upper pulleys 53 as needed. For example, it is preferable to install two or three, respectively, so that the driving force is 1/4 or 1/6. do.

The third wire 73 is provided between the upper rod 21 and the middle rod 23 and interlocks the withdrawing and entering of the middle rod 23 and the withdrawing and entering of the lower rod 22 .

That is, as shown in FIG. 1 , when the lower rod 22 is withdrawn from the middle rod 23 as the moving rod 51 rises, the third wire 73 is drawn into the middle rod 23 while the middle rod 23 is drawn. ) is drawn out from the Sangbong 21 , and when the middle rod 23 is drawn into the Sangbong 21 by the first wire 71 while the umbrella is folded, the third wire 73 is pulled out of the middle rod 23 . While being drawn out, the lower rod 22 is drawn into the middle rod 23 .

The third wire 73, for example, as shown in Figure 1, one end is fixed to the lower side of the upper rod 21, the other end is extended between the upper rod 21 and the middle rod 23, the middle rod (23) After being drawn into the middle rod 23 via the middle rod pulley 192 provided in the middle rod cap 121 of

The movable rod 51 is provided on the lower inner side of the lower rod 22 , and is moved up and down toward the upper fixing part 60 .

The push bar 25 extends from the upper end of the moving rod 51 and penetrates through the upper end of the lower bar 22 and is supported on the upper end of the middle bar 23 , and pushes the middle bar 23 as the moving rod 51 rises. The lower rod 22 is drawn out.

The push rod 25 may be provided in various types, for example, may be provided in a rod shape with both ends open, and both ends may have a plurality of rod shapes supported by the movable rod 51 and the middle rod cap 121, respectively. It can be provided as a support of

The winding portion 80 is provided on one side of the handle portion 17 to wind and unwind the second wire 72 .

The winding unit 80 may be provided in various types. For example, a driving force may be generated by any one of a motor or magnetic force, and a manual winding method may be used.

On the other hand, it may further include a winding fixing portion (not shown) for fixing the wound state of the winding portion (80). This means that when the winding part 80 is provided as a motor, the motor can generate torque only in one direction in which the second wire 72 is wound, and when the driving force is removed, it can be provided in a type that freely rotates in the opposite direction. , in this case, in order to prevent continuous driving force maintenance from occurring in the state in which the second wire 72 is wound, it is necessary to provide a winding fixing part so that the reverse rotation is not made.

The winding part 80 further includes an elastic part (not shown) that stores the restoring force when the winding part 80 is released, and when the umbrella 13 is folded by the restoring force of the folding spring (not shown), the elastic part The second wire 72 may be wound around the winding portion 80 by the restoring force.

This is, when the winding unit 80 is driven by using a power source such as a motor, if the winding unit 80 does not operate due to battery consumption during use, the multi-stage automatic umbrella may not operate properly.

For example, when the battery necessary for driving the winding unit 80 is discharged, in the folded state of the umbrella of FIG. is stored. When the user opens the umbrella, when the user pushes up the runner 30 with force and unfolds the umbrella flesh 13, the folding spring 16 is tensioned to store the restoring force. At this time, the second wire 72 in the winding portion 80 ) is not wound, the moving rod 51 does not move downward, and therefore the first wire 71 is also released to the outside without being drawn into the umbrella stand 20 . Accordingly, the first wire 71 and the second wire 72 are loosened and tangled in the inside and outside of the umbrella stand 20 in a state in which there is no tensile force, and thus the folding or unfolding operation of the umbrella may become impossible in the future.

Therefore, in order to prevent this, when the umbrella is unfolded (that is, when the winding portion 80 is unwound), when the winding portion 80 is further provided with an elastic portion that stores the restoring force in the winding direction, when the umbrella is unfolded By winding the second wire 72, a tensile force is applied to the second wire 72 and the first wire 71 so as not to be entangled with each other.
