Description

Wire-type Umbrella

The present invention relates to an umbrella, and more particularly, to a wire-type umbrella in which a mechanism for folding and unfolding an umbrella is implemented with two unfolding and folding wires and each wire maintains tension, thereby simplifying the configuration, reducing the weight, and reducing the manufacturing cost, and in which the umbrella can be opened and closed manually even when implemented as an electric automatic umbrella.

Umbrellas are increasingly diversifying in their uses and types beyond simply being tools to block rain, including parasols, golf umbrellas, manual umbrellas, and automatic umbrellas.

The traditionally used manual umbrella is composed of umbrella ribs, a pole, and a handle, and the user can open and close the umbrella by directly pushing up and down the runner. This manual method installs a number of springs between the umbrella ribs to store restoring force when opening the umbrella and use it when closing the umbrella. However, from the user's perspective, it is inconvenient to use because they have to add force to store restoring force when opening the umbrella.

Meanwhile, automatic umbrellas install connecting members such as thread or a number of gear trains inside the umbrella shaft and install a drive motor to drive them in the handle portion so that the umbrella can be opened and closed by pressing a button. However, this automatic method requires not only the power required to operate the connecting members or gear trains, but also the power to tension (or compress) the spring, so a drive motor with a large torque must be used, which increases the manufacturing cost and causes inconvenience in that the battery consumption is large and it must be replaced or recharged frequently.

Meanwhile, as disclosed in the patent publication No. 10-2023-0042361 "Fully automatic opening/closing umbrella", there is an aspect of improving the reliability of the opening/closing operation by using a rack, a worm gear, and a gear belt, but the power transmission structure is complex and there are many parts, making it difficult to assemble and increasing the manufacturing cost. In addition, since many components must be installed inside the center pole, the center pole becomes larger and heavier, which reduces the usability.

Accordingly, the purpose of the present invention is to provide a wire-type umbrella that can simplify and lighten the configuration and reduce manufacturing costs by implementing a folding and unfolding mechanism for the umbrella with two unfolding and folding wires.

In addition, the purpose of the present invention is to provide a wire-type umbrella that can prevent malfunction of the umbrella and improve product reliability and durability by correcting changes in length of the unfolding wire and/or the folding wire due to use or other causes through a tension member.

In addition, another purpose of the present invention is to provide a wire-type umbrella that is very easy to implement as an automatic umbrella by providing rotational power only to a pulley when applied to an automatic umbrella using a drive motor or the like, and in particular, can be operated with a single drive unit when a double pulley is used, thereby reducing manufacturing costs, weight and volume, and minimizing the power required for the opening and closing operation of the umbrella, thereby maximizing the period of use.

The above object is achieved by a wire-type umbrella including, according to the present invention, a middle bar, an upper cap provided on an upper portion of the middle bar, a runner slidably fitted onto the middle bar, and umbrella ribs connected to the upper cap and the runner, wherein the umbrella comprises: an unfolding wire, one end of which is fixed to the runner and pulls the runner up toward the upper cap to unfold the umbrella; a folding wire, one end of which is fixed to the runner and pulls the runner down toward the lower portion of the middle bar to fold the umbrella; a pulley provided on one side of the lower portion of the middle bar, to which the other ends of each of the unfolding wires and the folding wires are fixed, such that the unfolding wires and the folding wires are released and wound in opposite directions respectively according to rotation; and a tension member which allows each of the unfolding wires and the folding wires to be released and wound on the pulley while maintaining tension.

The above tension member may be provided as an elastic member between one end of one or both of the spreading wire and the folding wire and the fixed point of the runner.

Alternatively, the tension member may be provided as an elastic member provided on one or both of the unfolding wire and the folding wire that is not wound around the pulley.

Alternatively, the handle portion provided at the lower end of the center bar may be further included, the pulley may be provided inside the handle portion, and the tension portion may be provided between the pulley and the lower end of the center bar. In this case, the guide pin provided inside the handle portion and guiding one or both of the unfolding wire and the folding wire extending from the pulley to the lower end of the center bar may be further included, and the tension portion may be provided as an elastic member provided between the guide pin and one or both of the unfolding wire and the folding wire.

Here, the pulley may be provided in two pieces corresponding to the unfolding wire and the folding wire, respectively, or may be provided as one of the double pulleys in which the unfolding wire and the folding wire are wound in opposite directions so that the unfolding wire and the folding wire are unwound and wound in opposite directions according to the rotational direction.

Here, the handle part may further be provided at the lower end of the above-mentioned center peak, and the handle part may further include the pulley, a driving part for rotating the pulley, and an operating part for operating the driving part.

Here, it can be made possible to open and close the umbrella by manually pushing up or pulling down the runner without power being supplied to the driving motor.

Here, an unfolding fixing member for fixing the unfolded state of the umbrella may be further included.

According to the wire-type umbrella of the present invention, the mechanism for folding and unfolding the umbrella is implemented with two unfolding and folding wires, so that the configuration is simple and the manufacturing cost can be reduced, and due to the characteristics of the wire, weight reduction and miniaturization are possible.

In addition, according to the wire-type umbrella according to the present invention, even when applied to an automatic umbrella using a driving motor or the like, since rotational power only needs to be provided to the pulley, the implementation of the automatic umbrella is very easy, and especially when a double pulley is used, operation is possible with a single driving unit, so that not only the manufacturing cost is reduced, but also the weight and volume are reduced, and the power required for the opening and closing operation of the umbrella can be minimized, so that the period of use can be maximized.

In addition, according to the wire-type umbrella according to the present invention, the user can open and close the umbrella by pushing up or pulling the runner like a manual umbrella, so that it can be used even when the power of the driving unit is discharged, thereby maximizing user convenience.

Therefore, according to the wire-type umbrella of the present invention, even if the length of either or both of the unfolding wire and the folding wire changes due to use or other causes through the tension portion, it is possible to correct this, thereby preventing malfunction of the umbrella, thereby having the effect of improving product reliability and durability.

In addition, according to the wire-type umbrella of the present invention, since it is possible to offset local load due to sudden umbrella manipulation or local excessive tensile force, it has the advantage of preventing wire breakage and minimizing damage, thereby increasing durability.

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

A wire-type umbrella (1) according to one embodiment of the present invention comprises a central pole (10), an upper cap (11) provided on the upper portion of the central pole (10), a runner (20) slidably fitted to the central pole (10), and umbrella ribs (13) connected to the upper cap (11) and the runner (20), and comprises an unfolding wire (31), a folding wire (33), a pulley (40), and a tension member (50) that allows each unfolding wire (31) and each folding wire (33) to be unwound and wound around the pulley (40) while maintaining tension.

The unfolding wire (31) is fixed at one end to the runner (20) and pulls the runner (20) toward the upper cap (11) to unfold the umbrella.

As an example, referring to FIGS. 1 and 2, one end of the unfolding wire (31) is fixed to the runner (20), and the other end is introduced into the interior of the center pole (10) via the upper transit point (15) on one side of the upper portion of the center pole (10) and then fixed to the pulley (40). Accordingly, as shown in FIG. 2, when the pulley (40) rotates to wind the unfolding wire (31) while the umbrella is folded, the runner (20) to which one end of the unfolding wire (31) is fixed is pulled up toward the upper cap (11), so that the umbrella is unfolded as shown in FIG. 1.

Here, as long as the unfolding wire (31) according to the present invention can be raised by having both ends fixed to the runner (20) and the pulley (40), various routing methods using various routing points or additional components can be used without limitation, and it is to be noted that such various modified examples are within the scope of the present invention.

As an example, the spread wire (31) may be exposed to the outside of the center bar (10) between the runner (20) and the upper route point (15), in which case, as shown in FIG. 3, a wire guide (16) may be provided to the outside of the center bar (10). In addition, it goes without saying that various known configurations may be added to prevent damage such as breakage of the spread wire (31) due to interference with other configurations such as the umbrella rib (13) in the exposed section, or to prevent deterioration of the appearance due to exposure.

In the present invention, the material of the unfolding wire (31) (including the folding wire (33) described later) can be prepared as various known types as long as it can be wound or unwound around the pulley (40). Normally, a material that does not stretch in the longitudinal direction is generally used, but an elastic material is not excluded, and it goes without saying that an elastic material may be used depending on the case (degree of elasticity, etc.).

The folding wire (33) has one end fixed to the runner (20) and pulls the runner (20) down toward the bottom of the center pole (10) so that the umbrella is folded. As an example, as shown in FIGS. 1 and 2, the folding wire (33) has one end fixed to the runner (20) and the other end extended downward and fixed to the pulley (40). Accordingly, when the pulley (40) rotates and winds the folding wire (33), the runner (20) is pulled down toward the bottom of the center pole (10).

The folding wire (33) according to the present invention, like the aforementioned unfolding wire (31), can be used without limitation in various routing methods as long as it can pull the runner (20) downwards at both ends and when wound. For example, the folding wire (33) can be extended into the interior of the center bar (10), pass through one or more routing points, be exposed to the exterior of the center bar (10), and then be fixed to the runner (20).

Alternatively, as illustrated in FIG. 1, the folding wire (33) may be extended directly to the outside of the center bar (10) without passing through the inside of the center bar (10) and fixed to the runner (20). In this case, if the folding wire (33) is exposed to the outside of the center bar (10), there may be a risk of damage, interference with other components may occur, causing malfunction, and there may be a problem of deterioration of the appearance. To this end, as illustrated in FIGS. 3 and 4, a wire guide (16) in which the folding wire (33) is received may be provided on the outside of the center bar (10). Accordingly, the folding wire (33) extended from the pulley (40) is introduced into the wire guide (16) from the bottom of the center bar (10) and extended, and is drawn out to the outside of the runner (20) along the via pulley (23) provided on the runner (20) and fixed to the fixed point (21b). Here, the wire guide (16) can be modified in various ways other than the embodiment shown in Fig. 3. Meanwhile, the wire guide (16) described above can also be applied to the section where the previously described spreading wire (31) is exposed to the outside of the center bar (10).

A pulley (40) is provided on one side of the lower portion of the center bar (10), and the other end of each unfolding wire (31) and folding wire (33) is fixed thereto, so that the unfolding wire (31) and folding wire (33) are released and wound in opposite directions according to rotation.

Here, when a handle part (60) is provided at the bottom of the center pole (10), the pulley (40) can be provided inside the handle part (60). However, the location of the pulley (40) is not limited to the inside of the handle part (60), and can be provided in various locations such as outside the handle part (60). In addition, the pulley (40) corresponding to either the unfolding wire (31) or the folding wire (33) can be provided inside the handle part (60) and the other can be provided outside the handle part (60), and the location can be changed as needed.

The pulley (40) may be provided in various types. In one embodiment, two pulleys (40) may be provided to correspond to the unfolding wire (31) and the folding wire (33), respectively. In this case, two driving units (63) for rotating each pulley (40) may be provided.

Alternatively, in another embodiment illustrated in FIG. 4, the pulley (40) may be provided as a double pulley (40) in which the unfolding wires (31) and the folding wires (33) are wound in opposite directions so that the unfolding wires (31) and the folding wires (33) are unwound and wound in opposite directions according to the direction of rotation. In this case, the unfolding wire and the folding wire form a single loop (closed curve) with the runner and the pulley at both ends, and as the pulley (40) rotates, the unfolding wire (31) and the folding wire (33) are unwound or wound in opposite directions to each other, thereby performing a motion of pulling up or down the runner (20), thereby opening or closing the umbrella. Accordingly, the wire-type umbrella according to the present invention implements the mechanism for folding and unfolding the umbrella with two unfolding and folding wires, so that the configuration is simple, thereby reducing the manufacturing cost, and due to the characteristics of the wire, it is possible to reduce the weight and miniaturization.

Meanwhile, a wire-type umbrella (1) according to an embodiment of the present invention can be implemented as an automatic umbrella that rotates a pulley (40) through a driving unit (63). As an example, the driving unit (63) may include, for example, a driving motor that rotates the pulley (40), a power supply, and an operating unit (65) for operating the driving motor. In this case, when a handle unit (60) is provided at the lower end of the center pole (10), the pulley (40) and the driving unit (63) may be installed inside the handle unit (60), and the operating unit (65) may be installed outside the handle unit (60). In addition, the power supply unit may be provided with a terminal so that it can be charged from the outside, or the power supply unit may be provided so that it can be charged by separating it from the handle unit (60).

Here, if power is not supplied from the power supply to the drive motor or if the power supply is discharged, the drive unit (63) can be made not to restrict the rotation of the pulley (40). In this case, since the user can open and close the umbrella by pushing up or pulling the runner like a manual umbrella, it can be used as both an automatic umbrella and a manual umbrella, thereby maximizing the user's convenience.

In addition, according to the wire-type umbrella according to the present invention, even when applied to an automatic umbrella using a driving motor or the like, since rotational power only needs to be provided to the pulley, the implementation of the automatic umbrella is very easy, and especially when a double pulley is used, operation is possible with a single driving unit, so that not only the manufacturing cost is reduced, but also the weight and volume are reduced, and the power required for the opening and closing operation of the umbrella can be minimized, so that the period of use can be maximized.

Meanwhile, an unfolding fixing member that fixes the unfolded state of the umbrella (1) may be provided. The unfolding fixing member prevents the runner (20) from being pushed downward toward the center pole (10) by the weight of the umbrella ribs (13) and the cover when the umbrella (1) is unfolded.

The unfolding fixing member may be provided without limitation in various known types, and for example, may include an elastic projection (71) provided on one side of the runner (20) facing the center pole (10) so as to be elastically extendable and retractable, and an insertion hole (not shown) provided on one side of the center pole (10) corresponding to the position of the runner (20) in the unfolded state of the umbrella.

As an example, referring to FIG. 6, the runner (20) may be provided with an inner runner (20a) that is slidably fitted to the outside of the center shaft (10), and an outer runner (20b) that is provided on the outside of the inner runner (20a) and is provided to be able to move up and down relative to the inner runner (20a) by a set distance.

Meanwhile, one end of the unfolding wire (31) and the folding wire (33) are both fixed to one side of the outer runner (20b), as shown in Fig. 6.

Here, the movement of the inner runner (20a) and the outer runner (20b) when the umbrella (1) is opened and closed will be described. First, when the umbrella (1) is closed, the inner runner (20a) and the outer runner (b) are spaced apart as shown in (b) of Fig. 6. Accordingly, when the umbrella is opened, the outer runner (20b) rises first by the opening wire (31), and when the outer runner (20b) and the inner runner (20a) come into contact as shown in (a) of Fig. 6, the outer runner (20b) and the inner runner (20a) rise together along the center peak (10). Conversely, when the umbrella is folded, the outer runner (20b) is lowered first by the folding wire (33), and after being separated by the above-mentioned set distance, the inner runner (20a) and the outer runner (20b) are lowered together along the center peak (10).

In this embodiment, the unfolding fixing member includes an insertion hole (not shown) provided on one side of the center pole (10) corresponding to the position of the outer runner (20b) in the unfolded state of the umbrella, and an elastic protrusion (71) provided on the inner runner (20a) and inserted into the insertion hole.

The elastic protrusion (71) is positioned within the set distance in the state of Fig. 6 (b), so that interference between the elastic protrusion (71) and the external runner (20b) does not occur in the state of Fig. 6 (b). In addition, when the umbrella is unfolded as shown in Fig. 6 (a), the external runner (20b) that rises by the unfolding wire (31) interferes (pressures) and is drawn into the insertion hole. As a result, the unfolded state of the umbrella is fixed.

Conversely, as shown in (b) of Fig. 6, when the umbrella is folded, the outer runner (20b) descends first, and when the interference (pressure) on the elastic protrusion (71) is released, the elastic protrusion (71) is pulled out of the insertion hole by elastic force, and then the inner runner (20a) and the outer runner (20b) descend together to the lower portion of the center peak (10).

Here, as long as the position of the outer runner (20b) in the unfolded state of the umbrella is fixed by interference (pressure, etc. as described above) and release according to the relative movement of the outer runner (20b), it is of course possible to make various modifications without being limited to the above-described embodiment.

Accordingly, in the case of an automatic umbrella equipped with a driving unit (63), since the umbrella is supported in the opened state by the insertion projection, a separate drive for maintaining the opened state in the driving unit (63) is unnecessary, so power usage can be minimized and usage time can be maximized. In addition, in the case of using it as a manual umbrella without a driving unit (63), since the umbrella is maintained in the opened state by the opening fixing unit, there is an advantage that the user does not need to support the runner (20).

The tension unit (50) allows each unfolding wire (31) and folding wire (33) to be unwound and wound around the pulley (40) while maintaining tension. The tension unit (50) performs a function of correcting a change in the length of each wire that is initially set due to a change in the elasticity or other configuration of the unfolding wire (31) and/or the folding wire (33). For example, if the length of either the unfolding wire (31) or the folding wire (33) changes due to use or other reasons, one of the wires may not be completely unwound from the pulley (40) or may be unwound further, so that the runner (20) may not be positioned at the designated unfolding and folding positions, making it impossible to open and close the umbrella. Alternatively, even if the umbrella can be opened and closed, the runner (20) may not be fixed and may flow when the umbrella is folded or unfolded, thereby reducing the marketability of the umbrella. Therefore, the tension member (50) applies tension to each unfolding wire (31) and folding wire (33) to compensate for this.

The tension member (50) may be provided in various types, and for example, as shown in FIG. 3, may be provided as an elastic member provided between one end of the unfolding wire (31) and/or the folding wire (33) and the fixed point (21) of the runner (20). Accordingly, as the wires are stretched, the elastic member is stretched so that each wire maintains tension. Here, FIG. 3 illustrates the tension member (50) on the folding wire (33) side, but it goes without saying that the same or similar configuration may be applied to the unfolding wire (31) side as well.

Alternatively, as illustrated in FIG. 5, the tension member (50) may be provided on a side of the unfolding wire (31) and/or the folding wire (33) that is not wound around the pulley (40). For example, in the case of the unfolding wire (31), the tension member (50) may be provided as an elastic member as illustrated in FIG. 5 between the fixing point on the runner (20) side and the section that is not wound around the pulley (40).

Alternatively, the tension member (50) may be provided between the pulley (40) and the lower end of the center rod (10) when the pulley (40) is provided inside the handle member (60).

As an example, referring to FIG. 4, a guide pin (61) may be provided in the handle portion (60) to guide the unfolding wire (31) and/or the folding wire (33) extending from the pulley (40) to the lower end of the center bar (10). In this case, the tension portion (50) may be provided as an elastic member provided between the guide pin (61) and the unfolding wire (31) and/or the folding wire (33). That is, one end of the elastic member (50) is fixed to the guide pin (61a) and the other end is connected in a ring shape so that the folding wire (33) can move, so that when the folding wire (33) becomes long, it can be pulled toward the guide pin (61a) to adjust the expansion and contraction, and when the folding wire (33) becomes short, it can be adjusted in length by making the folding wire (33) straight.

Therefore, according to the wire-type umbrella of the present invention, even if the length of the unfolding wire and/or the folding wire changes due to use or other causes through the tension portion, it is possible to correct this, thereby preventing malfunction of the umbrella, thereby having the effect of improving product reliability and durability.

In addition, the tension member (50) has the advantage of preventing wire breakage and minimizing damage to increase durability by being able to absorb excess tensile force temporarily applied to the wire or local load near the transit point due to sudden umbrella operation, such as when the pulley (40) starts rotating.

Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto, and various modifications and variations are possible by those skilled in the art to which the present invention pertains within the scope of the technical idea of the present invention and the equivalent scope of the claims. Therefore, the disclosed embodiments should be considered from an illustrative rather than a restrictive viewpoint. The scope of the present invention is indicated by the claims, not the foregoing description, and all differences within the scope equivalent thereto should be interpreted as being included in the present invention.
