Abstract
The present invention relates to an automatic umbrella, comprising: an umbrella stem and a plurality of ribs extending radially from an upper nest at an upper end of the umbrella stem; a lower nest which is arranged outside the umbrella pole along the moving section of the longitudinal direction and can slide up and down; a stopper fixed to the umbrella stick corresponding to the lower part of the moving section; a plurality of lower auxiliary ribs with two ends respectively connected with the umbrella ribs and the lower nest; the winding wheel is arranged at the lower end of the umbrella rod and used for fixing one end of the folding stay rope and winding and unfolding the folding stay rope according to the operation of the control unit; the other end of the folding stay extends downwards through an upper passing point on one side of the upper end of the umbrella rod, then is fixed on one side of the lower nest through a lower passing point arranged on the stop piece, and when the winding wheel winds the folding stay, the lower nest is moved towards the stop piece, so that the umbrella rib is folded. Since the folding stay is not fixed to the rib but fixed to the lower nest, the possibility of interference with other structures such as the lower auxiliary rib is minimized by close fitting to the umbrella shaft, and even if repeated folding and unfolding actions are performed, malfunction or damage can be reduced as much as possible.
Description
Technical Field
The present invention relates to the technical field of automatic umbrellas, and more particularly, to an automatic umbrella in which a pulling rope is closely attached to an umbrella shaft or extended into a wire guide to minimize interference with other components (e.g., a lower auxiliary rib) and even the possibility of malfunction when repeatedly folded. In addition to minimizing damage, the user can manually push the lower nest up or down to open and fold the umbrella, even if the operation of the reel is not motorized or fails, it can be used normally.
Background
Recently, various types of umbrellas have been proposed that can be folded or unfolded without using manpower for the purpose of improving user convenience and differentiating products.
For example, the applicant of the present application has also proposed an embodiment of an "automatic umbrella" according to korean patent laid-open No. 10-2020-0123710, in which a connection member such as a pulling rope is used inside the shaft.
However, in the automatic umbrella using the pull rope, since one end of the pull rope is directly connected to the rib after being pulled out from the top of the umbrella shaft, when the umbrella is opened, the steel wire rope spans the interior of the umbrella, so that the appearance of the umbrella is deteriorated, the exposed steel pull rope may interfere with surrounding structures during the process of folding and opening the umbrella, and the damage caused by winding and other faults may occur, and the pull rope is exposed and is easily damaged.
In addition, since the pulling rope pulled out from the upper portion of the umbrella shaft is not practically fixed to all the ribs, the tension of the wire is concentrated on a specific rib, and there is a risk that not only the operation is not smooth, but also the possibility of damage due to repeated pulling force is increased.
Disclosure of Invention
Accordingly, it is an object of the present invention to provide an automatic umbrella that minimizes the possibility of interference with other components (e.g., lower auxiliary ribs) by closely contacting a pulling string with an umbrella shaft, and minimizes malfunction or damage even if repeated folding and unfolding actions are performed, since a folding line is fixed to not an umbrella rib but a lower nest.
Further, another object of the present invention is to provide an automatic umbrella which can be normally used even in the case where the operation of the reel is not electric or malfunctions, when the unfolding and folding pulling ropes are used, the user can manually push up or down the lower nest to open or fold the umbrella.
In addition, it is another object of the present invention to provide an automatic umbrella that guides an unfolding pulling rope and a folding pulling rope into a wire guide so as not to be exposed to the outside, and that can minimize malfunction or damage caused by interference with surrounding structures, thereby maximizing durability and improving the external appearance.

Here, when the umbrella shaft is a multi-stage umbrella divided into two or more stages, the lower nest is disposed to move on the uppermost shaft adjacent to the upper nest, and the stopper is disposed on the umbrella shaft corresponding to the lower end of the moving section.
Alternatively, according to another embodiment of the present invention, in an automatic umbrella, it includes: an umbrella stem and a plurality of ribs extending radially from an upper nest at an upper end of the umbrella stem; a lower nest which is arranged outside the umbrella pole along the moving section of the longitudinal direction and can slide up and down; a stopper fixed to the umbrella stick corresponding to the lower part of the moving section; a plurality of lower auxiliary ribs with two ends respectively connected with the umbrella ribs and the lower nest; the winding wheel is arranged at the lower end of the umbrella rod and used for fixing one end of the folding stay rope and winding and unfolding the folding stay rope according to the operation of the control unit; the other end of the folding stay is led to the outside of the umbrella rod through a first lower passing point and a second lower passing point which are arranged in the stop piece, then the folding stay is fixed on one side of the lower nest, and when the folding stay is wound by the winding wheel, the lower nest is moved towards the stop piece, so that the umbrella rib is folded.
In each of the above embodiments, the wire guide is provided on the outside of the umbrella stick corresponding to the movement section, and the pulling rope led out of the umbrella stick is guided to the wire guide.
In the above embodiments, the wire guide may be provided in the shape of a groove recessed into the shaft or protruding outward.
In the above embodiments, a wire buffer is provided in the lower nest to which the other end of the pulling rope is fixed, to allow the other end of the pulling rope to expand and contract.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Example 1 (FIG. 1)
The first embodiment of the present invention discloses an automatic umbrella 1 comprising an umbrella shaft 10, a plurality of ribs 13 radially unfolded in a longitudinal direction from an upper nest 11 at an upper end of the umbrella shaft 10, a lower nest 71, a stopper 72, a lower auxiliary rib 131, and a reel 30.
Wherein one end of the folding stay 42 is fixed to one side of the lower nest 71 via the lower passing point A2 provided on the stopper 72 from the reel 30 downward via the upper passing point 15 on the top side of the umbrella stick 10, and the lower nest 71 moves in the direction of the stopper 72 when the folding stay 42 is wound around the pulley 30, thereby folding the umbrella rib 13.
Referring to fig. 1, this embodiment will be described in detail.
The lower nest 71 is installed at the outside of the umbrella stick 10 to be slidable up and down in a moving section L provided in the longitudinal direction.
The lower nest 71 is generally provided in a ring shape or a cylindrical shape, is sleeved on the outside of the umbrella stick 10, and slides up and down along the umbrella stick 10.
In the travel section L, the lower nest 71 is positioned at the bottom when the rib 13 is folded, and the lower nest 71 is positioned at the top when the rib 13 is unfolded. Therefore, the uppermost position and the lowermost position of the lower nest 71 are the movement section L. The moving sections L have different lengths according to the structure of the umbrella.
The stopper 72 is fixed to the umbrella shaft 10 corresponding to the lower side of the movement section L.
Unlike the lower nest 71, the stopper 72 is a structure fixed at a predetermined position of the umbrella stick 10, and its shape can be adapted to various shapes that are possible via the folding stay 42.
The stopper 72 can be freely positioned below the movement section L so as not to interfere with the vertical sliding of the lower nest 71. For example, the stopper 72 may be provided at a position contacting the lower end of the moving section L, or may be provided at a position spaced a predetermined distance from the lower end of the moving section L.
Both ends of the lower auxiliary rib 131 are connected to the rib 13 and the lower nest 71, respectively, and a plurality of ribs are radially provided along the outer circumference of the lower nest 71. Therefore, when the lower nest 71 moves downward of the shaft 10, the connected lower auxiliary ribs 131 pull the ribs 13 to fold the umbrella, whereas when the lower nest 71 moves upward of the umbrella stand 10, the lower auxiliary ribs 131 push the ribs 13 upward to unfold the umbrella.
One end of the folding stay 42 is fixed to the reel 30, and the other end extends downward from the reel 30 via an upper passing point on the upper end side of the umbrella stick 10, and is then fixed to the lower nest 71 side via a lower passing point A2 provided on the stopper 72.
Wherein the upper transit point 15 may be disposed at various locations, such as inside the upper nest 11, and the upper transit point 15 and the lower transit point A2 may be disposed as various structures, such as pulleys, through which the folding drawstring 42 can pass.
One end of the unwinding rope 41 is fixed on the reel 30, and the other end extends into the umbrella shaft 10, passes through the upper passing point 15, is pulled to the outside of the umbrella shaft 10, and is then fixed at one side of the lower nest 71. Accordingly, when the unwinding rope 41 is wound around the pulley 30, the other end of the unwinding rope 41 pulls the lower nest 71 toward the upper nest 11, thereby unwinding the rib 13.
Here, since the wire 41 is not an essential component in the operation of expanding the umbrella rib 13 in the present invention, a gear structure other than the wire method or a structure in which the user directly pushes up the pulley 71 or the like may be used.
The reel 30 is provided at the lower end of the umbrella stick 10 such that one end of the folding stay 42 is fixed such that the folding stay 42 is wound and unwound while being rotated according to the operation of a control unit (not shown).
The reel 30 may be provided in various manners, such as a manual operation, or may be provided to perform a rotating operation using various kinds of energy such as electric power without using a user's force. For example, a driving motor (not shown) is provided at one side of the reel 30, and a control unit such as a switch or a button for operating the driving motor is provided so that the driving motor acts when the user presses the button, so that the reel 30 rotates.
On the other hand, when the unwinding rope 41 is wound, the folding rope 42 should be reversely released. Thus, the reel 30 can be provided as two elements rotating in opposite directions, so that each winding and unwinding takes place in opposite directions; it may be provided as one element, but the winding directions of the unwinding ropes 41 and the folding ropes 42 are opposite. In the latter case, for example, when the reel 30 rotates in the forward direction, the unwinding rope 41 is wound and the folding rope 42 is unwound, and when the reel 30 rotates in the reverse direction, the folding rope 42 is wound but the unwinding rope 41 is unwound.
Therefore, in the automatic umbrella 1 according to the first embodiment of the present invention, when the umbrella is folded, the winding reel 32 rotates and winds the folding stay 42, and the other end (i.e., the lower nest 71) of the folding stay 42 is pulled downward. In the direction of the stopper 72, the lower auxiliary rib 131 connected thereto descends as the lower nest 71 descends, thereby folding the rib 13. Conversely, when the umbrella is opened, the reel 31 rotates and winds the unwinding rope 41, the other end of the unwinding rope 41 pulls the lower nest 71 upward toward the upper nest 11, and the lower nest 71 drives the lower auxiliary rib 131 connected thereto to rise, so that the rib 13 is unwound.
Accordingly, in the automatic umbrella according to the present invention, since the folding stay 41 is not fixed to the rib 13 but fixed to the lower nest 71 via the stopper 72, it has an advantage of minimizing close contact with the umbrella stand and minimizing interference with other components (e.g., the lower auxiliary rib 131), even if repeated folding and unfolding actions are performed, as much as possible.
In addition, in the case of the automatic umbrella of the present invention, in which the unfolding pulling rope and the folding pulling rope are simultaneously used, the user can manually push the lower nest 71 upward or downward to open and fold the umbrella, so that the automatic umbrella can be normally used even in the case that the operation of the reel 30 is not electric or fails.
The wire guide 80 is disposed outside the umbrella stick 10 corresponding to the movement section L such that the folding stay 42 pulled out from the umbrella stick 10 is guided to the inside of the wire guide 80.
As shown in fig. 4 and 5, one end of the wire guide 80 may be provided in a groove shape or a tubular shape so that the folding drawstring 42 or the unfolding drawstring 41 is not exposed to the outside.
The wire guide 80 may be formed to be recessed inward of the umbrella stick 10 as shown in fig. 4, or may be formed to protrude outward of the umbrella stick 10 as shown in fig. 5. In addition, the shape of the wire guide 80 may have various cross-sectional shapes as shown in fig. 4 and 5 without limitation.
On the other hand, the unwinding rope 41 or the folding rope may be guided into the wire guide 80 only after passing through the upper transit point 15 or the lower transit point A2 (see 41a in fig. 4 (a) or 42b in fig. 4 (b)), or may extend back and forth into the inside of the wire guide 80 via the upper transit point (see 42a or 42b in fig. 4 (a)).
Therefore, according to the automatic umbrella of the present invention, since the unfolding pulling rope 41 and the folding pulling rope 42 extend inside the wire guide 80 and are not exposed to the outside, it is possible to minimize damage or damage caused by interference with surrounding components, thereby maximizing durability and improving the external appearance.
The wire buffer 60 is disposed on the lower nest 71, and the other end of the unfolding pulling wire 41 or the folding pulling wire 42 is fixed to the lower nest 71 such that the other end of the fixed unfolding pulling wire 41 or the folding pulling wire 42 can be extended and contracted.
The wire buffer 60 is a component for compensating for a change in the length of the unwinding and folding stay 41 and 42 due to a change in the length of the stay according to the use of the automatic umbrella 1 or a deformation of other components such as the reel 30. That is, in the wire-driven automatic umbrella of the present invention, if winding and unwinding of each pulling rope are unevenly performed, a malfunction may occur.
The line buffers 60 may be provided in a variety of ways, for example, as shown in fig. 6, a buffer 61 may be provided between the lower nest 71 and the fixing point 63. The buffer 61 may be provided in various types having elasticity, such as a spring ((a) in fig. 6) or rubber ((b) in fig. 6). Therefore, when the lengths of the folding stay 41 and the unfolding stay 42 are insufficient, the additional length is provided to the folding stay 41 and the unfolding stay 42 while being compressed, whereas in the case where the lengths are excessive, the buffer member 61 expands and the lengths of the folding stay 41 and the unfolding stay 42 increase. It can accommodate the remaining length, which has the advantage of maintaining the substantial tension of the fold line 41 and the unfold line 42 in any of the above cases.
Therefore, according to the automatic umbrella of the present invention, by configuring the wire buffer 60, it is possible to automatically compensate for the variation in the length of the pulling wire while keeping the tension of the pulling wire constant, thereby preventing malfunction in advance.
Second embodiment (FIG. 2)
Referring to fig. 2, the automatic umbrella 1 according to the second embodiment of the present invention will be described in detail. Hereinafter, the description repeated with the first embodiment will be omitted.
The automatic umbrella 1 according to the second embodiment of the present invention relates to a multi-stage umbrella in which the umbrella shaft 10 is divided into two or more, as shown in fig. 2, which may be provided as a three-stage umbrella such as including an upper shaft 10a, a middle shaft 10b and a lower shaft 10c, or may be provided in two or more stages.
In this case, since the lower nest 71 is generally moved in the upper bar 10a, the stoppers 72 may be provided together in the upper bar 10a, but as described above, the position of the stoppers 72 is the lower part of the movement section (since the position is not limited as long as it is at L), and therefore the lower nest 71 may be provided on the upper bar 10a, and the stoppers 72 may be provided on the middle bar 10b or the lower bar 10 c. In addition, similarly, the lower nest 71 and the stopper 72 may be disposed at various positions, for example, together on the center pole 10b, according to the movement section L of the lower nest 71.
On the other hand, the wire guide 80 may be provided only on the upper rod 10a, or may be provided on the upper rod 10a and the middle rod 10b depending on the portions where the deployment string 41 and the folding string 42 are extended. Various variations are possible.
Hereinafter, since the operation process of the automatic umbrella 1 according to the second embodiment is the same as that of the first embodiment described above, a description thereof will be omitted.
Therefore, the automatic umbrella according to the present invention can be applied not only to a single-stage umbrella but also to a multi-stage automatic umbrella having two or more stages, and thus has great versatility.
Third embodiment (FIG. 3)
In the automatic umbrella 1 according to the third embodiment of the present invention, since the stopper 72 is disposed at the side of the lower end of the umbrella stick 10 near the reel 30, the folding stay 42 is fixed to the lower nest 71 after being pulled out of the umbrella stick 10 from the first lower transit point a21 and the second lower transit point a22 of the lower portion of the umbrella stick 10, not through the upper transit point 15.
Therefore, in the automatic umbrella of the present embodiment, since the folding stay 42 does not pass through the top of the umbrella stick 10, the length of the stay can be shortened, and the possibility of the unfolding stay 41 and the folding stay 42 interfering with each other does not occur. The size of the umbrella pole can be reduced to the maximum extent, thereby improving durability and maximizing effect.
As in the above-described embodiments, the present embodiment omits a description of equally applicable components (e.g., the wire guide 80 and the wire buffer 60).
While the present invention has been described with respect to a limited number of embodiments and drawings, the scope of the present invention is not limited thereto, and any changes or substitutions that would be apparent to those skilled in the art within the scope of the present invention should be included within the scope of the present invention.

Technical effects
Therefore, according to the automatic umbrella of the present invention, since the folding stay is not fixed to the rib but fixed to the lower nest through the stopper, it can minimize the possibility of interference with other configurations such as the lower auxiliary rib, thereby minimizing malfunction or damage even when folding and unfolding are repeated.
In addition, according to the automatic umbrella of the present invention, in case of using both the unfolding pulling rope and the folding pulling rope, the user can manually push or put down the lower nest to open and fold the umbrella, and in case that the operation of the reel is not electric or fails, the automatic umbrella can be normally used.
In addition, according to the automatic umbrella of the present invention, the unfolding pulling rope and the folding pulling rope are extended to the inside of the wire guide without being exposed to the outside, so that breakage or damage caused by interference with surrounding parts can be minimized, thereby maximizing durability and improving the external appearance.
In addition, according to the automatic umbrella of the present invention, by configuring the wire buffer, the length change of the pull rope is automatically compensated while the tension of the pull rope is kept constant, so that the occurrence of malfunction can be prevented.
