Fig. 2 is a schematic cross-sectional view of the unfolded and manually folded multifold folding umbrella shown in Fig. 1; Fig.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, a manual folding and folding multifold folding umbrella 1 according to an embodiment of the present invention includes an umbrella flesh 101, a reamer 110, a middle rod 120, and a lower rod 130 And a handle 140. The first wire 10 and the second wire 10 allow the mutual movement of the reaming rod 110, the middle rod 120 and the lower rod 130 when the umbrella is extended and folded, 20 and the third wire 30 and a wire fixing part 40 for fixing one end of the third wire 30 and an upper end of the wire fixing part 40 and the middle rod 120 are kept constant And a fixed rod 50.

Accordingly, the manual opening / closing multi-stage folding umbrella 1 according to the embodiment of the present invention can minimize the operation distance for pulling out the umbrella when the umbrella is folded, and automatically folds the folded umbrella when folded .

Hereinafter, each configuration will be described.

The first wire 10 is fixed to a clasp 150 which is moved upward and downward along one side of the outer side of the reamer 110 and the other end of the first wire 10 is inserted into the reamer 110 from one side of the upper end of the reamer 110, 120).

The first wire 10 is interlocked with the vertical movement of the latch 150 in accordance with the relative movement of the ream 110 and the lower rod 130 so that the umbrella 101 coupled to the latch can be folded and unfolded.

1, the other end of the first wire 10 is fixed to one side of the upper end of the middle rod 120 when the reel 110 moves away from the middle rod 120 to the state of FIG. 2 The first wire 10 is pulled into the inside of the ream 110 as a result of the lowering of the middle rod 120. As a result, the first wire 10 is pulled up to the upper end of the ream 110 as a result.

On the other hand, when the umbrella is folded, as shown in FIG. 2, when the umbrella fingers are folded, the restoring force of the folding spring 160 acts to fold the umbrella flesh 101 downward, The wire 10 is drawn out to the outside of the ream 110, and as a result, the middle rod 120 is pulled into the ream 110 to pull it in.

One end of the second wire 20 is fixed to one side of the lower end of the reamer 110 and the other end of the second wire 20 extends to the outside of the middle rod 120 to enter the middle rod 120 from the upper end of the middle rod 120, (130).

The second wire 20 allows the relative movement of the reamer 110 and the middle rod 120 to operate in conjunction with the relative movement of the middle rod 120 and the lower rod 130.

That is, when the umbrella is unfolded, when the middle rod 120 is pushed up from the lower rod 130 in FIG. 1, the second wire 20 is drawn into the middle rod 120, The middle rod 120 is also pulled out of the rearmost 110 because one end of the rearmost rod 110 is fixed to the inner lower end of the rearmost 110. [

In other words, the operation of the user is to perform one operation of pushing the middle bar 120 from the lower bar 130, and thereby, the function of the middle bar 120 to be pulled out of the reunion 110.

Therefore, in the case of the conventional three-stage umbrella, the umbrella must be pushed up so as to pull out all of the ream 110 by pushing up the ream 110 by the other hand while holding the lower rod 130 with one hand, b length), in the case of the manual folding and folding multifold folding umbrella 1 according to the present invention, all of the ream 110 is pulled out by simply pulling the middle bar 120 (see length a in FIG. 2) When the umbrella is deployed, the required operating distance is reduced, maximizing user convenience.

On the other hand, when the umbrella is folded, when the middle rod 120 is pulled into the reamer 110 by the folding spring 160, the second wire 20 is drawn out from the inside of the middle rod 120 to the outside, The fixed bottom bar 130 is inserted into the inside of the middle bar 120. [

Here, the grip portion 60 may be further provided on a lower side (see FIG. 1) of the rearing bar 110 or a lower side (see FIG. 2) of the middle bar 120 for facilitating the user's pulling out operation.

In this case, since the user does not have to take out the latch 150 to which the umbrella fingers 101 are connected, it is possible to prevent a safety accident caused by a wrong grip.

The third wire 30 is fixed at one end to the spiral part 170 provided at the handle 140 and the other end extends to the inside of the bottom bar 130 and passes through the upper end of the bottom bar 130, And is fixed to the wire fixing portion 40 provided.

The third wire 30 is wound and fixed on the spool part 170 in a state in which the umbrella is unfolded, thereby preventing the restoring force of the folding spring 160 from being exerted, thereby maintaining the unfolded state of the umbrella.

The spool part 170 may further include a spiral spring (not shown) for storing the restoring force when the umbrella is folded and winding the third wire 30 when the umbrella is unfolded have.

That is, when the umbrella is expanded as shown in FIG. 2, the winding spring stores the restoring force in a state in which the umbrella is folded (the state where the third wire 30 is fully released) as shown in FIG. The third wire 30 wound around the winding portion 170 is wound.

Accordingly, since the third wire 30 is always held with the tensile force by the winding spring, the third wire 30 is twisted inside the lower bar 130, thereby preventing a malfunction that may occur.

In the state in which the umbrella is completely opened (FIG. 2), the third wire 30 is fixed so as not to be unintentionally loosened by the tightening portion (not shown), so that the umbrella can be maintained in a fully extended state.

Here, the winding spring may be provided in various types, for example, a coil spring provided in the winding portion.

Alternatively, a drive motor may be provided to perform the same function as the take-up spring, or various structures capable of causing restoration by other magnetic forces may be applied without limitation.

Although the first wire 10, the second wire 20 and the third wire 30 are connected by a single pulley, the first wire 10, the second wire 20 and the third wire 30 may be connected by using a plurality of pulleys. That is, if the length of the wire is extended by using a plurality of pulleys, the power required for operation of each umbrella stand can be reduced by the work principle.

Therefore, when the first wire 10 or the second wire 20 is made up of a plurality of pulleys, the force applied by the user when the umbrella is extended can be reduced. When the third wire 30 is connected by a plurality of pulleys It is possible to reduce the force exerted by the winding spring or the driving motor.

However, even when a plurality of pulleys are used as described above, it is obvious that they are included in the scope of the present invention.

The wire fixing part 40 is provided so as to be movable up and down within the lower bar 130 in a state where the other end of the third wire 30 is fixed.

Up and down movement of the wire fixing portion 40 is performed by the fixing rod 50. [

The fixing rod 50 is provided between the wire fixing part 40 and one side of the upper end of the middle bar 120 so that the wire fixing part 40 and the upper end of the middle bar 120 maintain a constant distance.

When the umbrella is deployed, the wire fixing portion 40 fixed to the fixing rod 50 is moved upward from the inside of the lower bar 130 together when the middle bar 120 is separated from the upper portion of the lower bar 130 When the umbrella is folded, when the middle bar 120 moves toward the lower bar 130, the wire fixing part 40 is pulled down and the third wire 30 is drawn out of the spool part 170.

On the other hand, the fixing rod 50 prevents the middle rod 120 from being pushed down toward the lower rod 130 in a state in which the umbrella is unfolded. That is, since the fixed length of the fixed rod 50 does not vary not only with the tensile force but also with the compressive force, the middle rod 120 is prevented from descending due to its own weight toward the lower rod 130.

The fixed rod 50 may be provided in various ways and is fixed at one end to the wire fixing portion 40 and at the other end to be fixed to one end of the upper end of the middle rod 120 through the upper end of the lower rod 130 .

The folding spring 160 stores the restoring force in the state where the umbrella is unfolded so that the umbrella flesh 101 is folded.

As shown in FIG. 2, the folding spring 160 may be provided as a tension spring which is provided between the umbrella fingers 101 to store the restoring force by being stretched when the umbrella is expanded, And may be provided as a compression spring for storing the restoring force while being compressed. Alternatively, it may be provided at a position other than the umbrella flesh 101.

The unfolding fixture maintains and releases the umbrella unfolded state according to the user's operation.

For example, the spread and fixed portion may be provided at one side of the spool portion 170 to prevent the third wire 30 from being unwound from the spool portion 170 in a state in which the umbrella is unfolded It can be prepared by the government. Specifically, various structures for preventing rotation of the roll on which the third wire 30 is wound can be used.

Alternatively, a hang-up method in which the spread fixing portion is used in a normal umbrella can be used. That is, a through hole is provided at the lower end of the middle rod 120, and a hooking protrusion is provided at one end of the upper end of the corresponding lowering bar 130 so as to be drawn in and out of the inner bar 130, A structure may be used in which the locking protrusion is drawn out to the outside of the middle bar 120 and fixed so that the middle bar 120 and the lower bar 130 can not be moved relative to each other.
