Description

{MULTI-FOLDING AUTOMATIC UMBRELLA}

The present invention proposes a structure for reducing the force required for driving in a multi-stage automatic umbrella using a driving force such as a motor or a magnetic force. By using a driving motor, a driving motor with a low torque can be used. The present invention relates to a multi-stage automatic umbrella capable of reducing battery consumption.

Recently, a variety of multi-stage automatic umbrellas have been proposed for folding or unfolding umbrellas for user convenience and product differentiation without the use of human power.

For example, the multi-stage automatic umbrella is provided with a connecting member such as a thread or a plurality of gear trains in the umbrella stand, and a drive motor for driving the gear is disposed on the handle so that the operation of the drive motor is controlled by a button .

However, in order to fold or unfold the entire umbrella with the driving motor, a force for compressing (or tensioning) the expanding spring (or the folding spring) is required in addition to the force necessary for the above-described connecting member or gear heating operation. There is a problem in that the manufacturing cost is increased. As the torque is increased, the battery consumption is increased, so that the user has to inconveniently replace or charge the battery frequently.

Further, when the above-mentioned multi-step automatic umbrella does not operate because the battery is discharged during use, the umbrella itself can not be folded or unfolded, thereby failing to function as the umbrella itself.

First, a multi-stage automatic umbrella 1 according to an embodiment of the present invention includes a hollow reamer 21 and a middle rod 23, and a reamer cap 11 coupled to an upper portion of the reamer 21, A spreader 15 provided between the umbrella fence 13 and the runner 30 and a pull handle 15 provided under the lower rod 22 in the radial direction of the reinser cap 11, 17).

The reamer 21 and the lower bar 22 are provided in a hollow cylindrical shape.

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

The runner 30 is radially engaged with a plurality of spreading fingers 15 along the periphery so that when the runner 30 is positioned below the rearing bar 21 as shown in Figures 1 or 2, ) Moves downward along the runner 30 to pull down the umbrella and collapse the umbrella.

On the other hand, when the runner 30 is lifted up to the rearmost cap 11 side as shown in FIG. 2, the spreader 15 pushes up the umbrella 13 to unfold the umbrella.

At this time, a folding spring 16 is provided between the spreading fingers 15 and the umbrella fingers 13. The folding spring 16 stores the restoring force when the umbrella is unfolded, and then the driving force Is released, the umbrella piece 13 is folded by the restoring force.

One end of a 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 lower bar 22 to interlock the up and down movement of the runner 30 and the withdrawal of the lower bar 22 relative to the reamer 21.

That is, when the runner 30 descends to the lower side of the reamer 21, the first wire 71 draws the lower rod 22 into the reamer 21, and when the lower rod 22 is pulled out of the reamer 21, (30) to the upper portion of the reamer (21).

1, the first wire 71 is fixed to the runner 30 at one end and the other end is connected to a reed bar 191 provided in the reed cap 11 of the reed bar 21, And can be fixed to the lower end cap 122 of the lower bar 22 after being pulled into the reed bar 21.

The third wire 73 is provided between the reamer 21 and the moving rod 60 to interlock the up and down movement of the lower rod 22 with the up and down movement of the moving rod 60.

1 and 3, the second wire 72 pulls up the moving rod 60 to the inner upper side of the lower bar 22 when the lower bar 22 is pulled into the reamer 21, When the rod 60 is pulled down to the inner lower portion of the lower bar 22, the lower bar 22 is pulled out from the reamer 21.

1, one end of the third wire 73 is fixed to a lower one side of the reamer 21 and the other end is passed between the reamer 21 and the lower rod 22, And can be fixed to the moving rod 60 after being pulled into the bottom bar 22 via the bottom barrel 193 provided on the cap 122.

2, the other end of the third wire 73 is pulled into the lower bar 22 and then is guided to the lower bar cap 122 via the upper pulley 43 provided on the moving rod 60 It may be fixed.

The moving distance of the moving rod 60 is set to a half of the length of the third wire 73 drawn into the lower bar 22 do. Therefore, by adjusting the number of the upper pulley 43 and the lower pulley 193, the moving distance of the moving rod 60 can be adjusted to the moving distance of the lower bar 22 when the lower bar 22 is drawn out.

The lower fixing portion 51 is fixed to the lower side of the lower bar 22 facing the handle portion 17.

The lower fixing portion 51 is fixed in position unlike the moving rod 60 described later and is moved downward or upward by the second wire 72 connected with the moving rod 60 It is separated.

1, the second wire 72 is connected to the moving rod 60 via the lower pulley 53 of the moving rod 60 and the lower pulley 53 of the lower fixing part 51, When the second wire 72 is wound by the winding portion 80, the lower moving rod 62 approaches the lower fixing portion 51 as shown in FIG.

The second wire 72 is provided over the winding portion 80, the lower fixing portion 51 and the moving rod 60 to interlock the winding and unwinding of the winding portion 80 and the upward and downward movement of the moving rod 60 .

1, when the second wire 72 is wound on the spiral part 80, the second wire 72 passed between the moving rod 60 and the lower fixing part 51 is wound around the spiral part 80 So that the moving rod 60 is moved downward toward the fixed lower fixing portion 51.

1 and 2, the second wire 72 is fixed at one end to the spool portion 80 and the other end is connected to a plurality of lower pulleys (not shown) provided at the moving rod 60 and the lower fixing portion 51, Is fixed to either the moving rod (60) or the lower fixing portion (51) via the guide portion (53).

A plurality of lower pulleys 53 are provided between the moving rod 60 and the lower fixing part 51 and the number of the lower pulleys 53 is adjustable corresponding to the driving force of the spool part 80.

That is, when the number of the lower pulleys 53 increases and the second wire 72 passes through the lower number of the lower pulleys 53, for example, as shown in FIGS. 1 and 2, When the second wire 72 is provided between the moving rod 60 and the lower fixing portion 51 by the guide wire 53 and the guide wire 53 is provided six times, The second wire 72 of the double length must be wound.

Therefore, when applying the same principle, when the same work W is required to fold the umbrella, the length S of winding the second wire 72 is increased six times, The driving force required to wind the motor is reduced to 1/6.

Therefore, if the number of the lower pulleys 53 is increased to thereby increase the winding distance of the second wire 72, the umbrella can be folded with less driving force, so that a driving motor having a low torque can be used when the driving motor is used , It is possible to reduce the amount of battery consumption when using a drive motor having the same torque.

If the number of the lower pulleys 53 is excessively increased in order to lower the driving force, the time required for winding the second wire 72 may be increased. On the other hand, if the number of the lower pulleys 53 is too small, It is preferable that the number of the lower pulleys 53 be selected as appropriate according to need. For example, it is preferable that the number of the lower pulleys 53 is set to two or three, and the driving force is set to 1/4 or 1/6 Do.

The lower pulley 193 and the upper pulley 43 can be provided in plural numbers as the number of the upper pulleys 43 increases and the distance of the moving rod 60 becomes shorter as the number of the upper pulleys 43 increases. Is preferably provided in a larger number than the number of the upper pulleys 43.

The moving rod 60 is provided inside the lower bar 22 and is moved up and down between the lower fixed portion 51 and the lower bar cap 122 of the lower bar 22. [

The moving rods 60 may be provided in one piece so that the upper pulley 43 is provided on the upper side and the lower pulley 53 is provided on the lower side. .

The spool part 80 is provided at one side of the grip part 17 to perform winding and unwinding of the second wire 72.

The spool 80 may be provided in various types. For example, the spool 80 may generate a driving force by either a motor or a magnetic force, and a manual winding method may be used.

On the other hand, it may further include a winding portion (not shown) for fixing the winding state of the winding portion 80. When the spool 80 is provided with a motor, the motor can be provided with a type that can generate torque only in one direction that winds the second wire 72, and freely rotates in the opposite direction when the driving force is removed. In this case, in order to prevent the continuation of the driving force from being generated in the state that the second wire 72 is wound, it is necessary to provide a mechanism for reducing the reverse rotation.

The spool part 80 further includes an elastic part (not shown) in which a restoring force is stored when the spool part 80 is released. When the umbrella spool 13 is folded by a restoring force of a folding spring (not shown) The second wire 72 can be wound around the winding portion 80 by the restoring force.

This is because, when the spool part 80 is driven by using a power source such as a motor, the multi-stage automatic umbrella may not operate properly if the spool part 80 does not operate because the battery is consumed during use.

For example, when the battery necessary for driving the spool part 80 is discharged, in the folded state of the umbrella of Fig. 1, the second wire 72 is loosened to the spool part 80, It is stored. When the umbrella is unfolded, when the user pushes the runner 30 by force to unfold the umbrella piece 13, the folding spring 16 is pulled to store the restoring force. At this time, the second wire 72 The moving rod 60 does not move downward and thus the first wire 71 is not pulled into the umbrella frame 20 but is released to the outside. Therefore, the first wire 71 and the second wire 72 are loosened and entangled in the inner and outer portions of the umbrella frame 20 in a state of no tension, so that the subsequent folding or unfolding operation of the umbrella can become impossible.

Therefore, in order to prevent this, when the umbrella is unfolded (that is, when the spool part 80 is released) and the elastic part for storing the restoring force in the direction in which the spool part 80 is wound is further provided, By winding the second wire 72, tension is applied to the second wire 72 and the first wire 71 to prevent them from tangling with each other.
