Description

  The present invention relates to an improvement of an umbrella with an umbrella winding.

Conventionally, a structure disclosed in Japanese Patent Application Laid-Open No. 11-155619 is known as an umbrella with an umbrella wrap around which an umbrella is naturally wound around a handle shaft at the same time as the umbrella is folded.
In other words, this umbrella-wrapped umbrella is configured such that the umbrella is folded along the middle fold formed in the radial direction in the middle of the umbrella stretched between adjacent skeletons, and from each middle fold. An umbrella bending / winding means for winding the umbrella in a curved shape or a spiral shape is attached to both or one side of the umbrella folding section to the main bones on both sides.
Then, when the umbrella is opened, the umbrella bending / winding means is fully extended, and when the umbrella is closed, the umbrella bending / winding means is operated to be folded for each umbrella between the parent bones. It is designed to be wound in a spiral.
However, in the above configuration, since the umbrella bending / winding means is attached to both or one side of the umbrella folding section from each middle fold to the master bones on both sides thereof, the upper ends of the umbrellas are individually provided. There was a drawback of winding in a spiral.
Therefore, in order to align and cleanly align the umbrella when the umbrella is closed, the lower (center side) umbrella portion not attached with the umbrella bending / winding means is aligned in advance, and the umbrella bending / winding is performed. It was necessary to apply the urging force of the attaching means.
In addition, in the present invention, since a spiral energizing force is applied, a planar elastic force is applied, and it is difficult to wind it three-dimensionally along the handle axis.
JP 11-155619 A

The present invention has been made in view of the above circumstances, and its main problem is that when folding an umbrella, the umbrella can be wound three-dimensionally along the handle axis in a three-dimensional shape. To provide an umbrella.
Another object of the present invention is to provide an umbrella with an umbrella wrapping that can wrap an umbrella along a handle axis even in a folding umbrella.

In order to solve the above problem, the invention of claim 1
In the umbrella with umbrella wrapping, the umbrella is folded along the middle fold formed in the radial direction around the tip of the handle shaft in the middle of the umbrella stretched between adjacent bones,
Proximal end of the in crease in a straightened against its biasing force to the take-dressing biasing member made of a strip-shaped spring material or a synthetic resin with a flat plate which is urged in a spiral shape along the center-folding th Attached from the side to the midway position or from the base side to the tip side,
When the umbrella is opened, the umbrella spreads against the urging force of the winding urging member, and when the umbrella is closed, the urging force of the wrapping urging member folds for each umbrella between the main bones. Technical measures are taken such that the eyes are folded and wound in a spiral shape along the handle axis.
In the invention of claim 2,
The umbrella with an umbrella roll consists of a folding umbrella whose handle axis can be expanded and contracted and whose parent bone can be expanded and contracted at the folding point,
The winding urging member is attached from the base end side of the middle fold to a position that is less than the folding point of the main skeleton of the folding umbrella, or in a position corresponding to the folding point when exceeding the folding point. We are taking technical measures to separate them.
In the invention of claim 3,
Technical measures are taken that the winding biasing member is made of a belt-like synthetic resin fiber.

As described above, according to the present invention, when the umbrella is closed, the winding biasing member acts to wind the umbrella between the main bones spirally along the handle axis with the biasing force acting at the middle fold. .
Moreover, since the front end of the middle fold is in a free state, it is folded according to the urging force in accordance with the winding direction, so that the umbrella can be folded smoothly.
As described above, in the present invention, the winding urging member is attached along the middle fold line, so that even a folding umbrella can be applied, which is extremely useful.

Hereinafter, embodiments of an umbrella with an umbrella winding of the present invention will be described with reference to the drawings.
1 to FIG. 3 shows an umbrella with umbrella windings, in which a large number of main bones 2 are pivoted radially around the tip 1a of the handle shaft 1, and the handle shaft 1 is slid up and down. An intermediate portion of the short sheath tube 3 and the parent bone 2 is connected by a receiving bone 4.
And it has a publicly known configuration in which the main bone 2 is opened and closed by moving the short sheath tube 3 up and down to open and close the umbrella 5 stretched around the main bone 2.

That is, the umbrella 5 is stretched along the main bone 2, and is a middle fold A formed between the adjacent main bones 2, 2 in a substantially radial direction around the distal end portion 1 a of the handle shaft 1. Is formed.
The middle fold A is a fold formed when the umbrella is closed, and the umbrella 5 is folded along the middle fold A.
In the present invention, a winding biasing member 6 biased in a spiral shape is attached inside the umbrella 5 along the middle fold A.

As the winding urging member 6, a spring material urged in a spiral shape or a synthetic resin having the above-described spring property can be used. In this embodiment, the urging force member 6 is urged in a spiral shape as shown in FIG. A flat spiral winding spring is used.
This flat spiral winding spring uses a band-shaped synthetic resin as a material, but may be a flat metal.

A flat spiral winding spring shown as an example of the winding urging member 6 in FIG. 7A is a belt-like shape and is urged in a twisting direction with respect to a central vertical line. Accordingly, as shown in FIG. 7B, it is returned to a straight line and fixed to the umbrella 5 by bonding or the like, and the umbrella 5 is urged in a direction to be wound around the handle shaft 1.
Further, the tip 6a of the flat spiral winding spring is cut so as to be gradually narrowed so that the tip 6a does not interfere with storage when the umbrella is closed.

  As shown in FIG. 5 (the illustrated example is a folding umbrella, but it is not necessary to be a folding umbrella as in the above embodiment), the winding biasing member 6 is formed from the tip of the handle shaft 1. It is preferable to dispose the tip 6a at a slightly separated position and fix it to the umbrella 5 and by narrowing the tip 6a, the tip of the umbrella does not become bulky when the umbrella is closed.

Further, in this embodiment, the winding biasing member 6 extends from the base end side of the middle fold A to the midway position, and has a configuration that is not attached to the tip of the middle fold A.
This is because when the urging force of the wrapping urging member 6 is strong, when the wrapping urging member 6 is attached to the tip of the middle fold A, the urging force also acts on the tip (upper end) when the umbrella is closed, This is because each middle fold A may be wound, and even if the upper end side is in a free state, the tip of the middle fold A can be neatly aligned.
As the midway position, for example, since the umbrella 5 is folded and wound and then stopped by the winding band 10, the vicinity of the winding band 10 is preferable.

The present invention is not limited to the above embodiment, and the winding biasing member 6 is fixed along the middle fold A from the base end side to the upper end side of the middle fold A as shown in the second embodiment of FIG. It is good also as composition to do.
In this case, by adjusting (weakening) the urging force of the winding urging member 6, it is possible to prevent the upper end from being wound at each middle fold.
In this case, the winding urging member 6 may have the same urging force as a whole, but, for example, a configuration in which the central portion is the strongest (or wider or thicker) and the upper and lower portions are weaker (or thinner). It may be.

Since it is constituted in this way, when the short sheath tube 3 is raised and the umbrella is opened, the umbrella fabric 5 spreads against the urging force of the winding urging member 6 and the umbrella is closed. Can be wound in a spiral shape along the handle axis 1 by folding the middle fold A for each umbrella between the main bones 2 by the urging force of the winding urging member 6.
The direction of winding the umbrella 5 between the main bones 2 in the spiral shape is the same in the middle fold A, but may be a combination of the same direction and the opposite direction.

In the illustrated example, the case where the winding biasing member 6 is connected in series is exemplified, but a plurality of parts may be divided.
Alternatively, the winding urging member 6 may not be provided on the base end (lower end) side of the middle fold A, but may be provided only at an intermediate position excluding the base end and the tip of the middle fold A.
Further, the attachment of the winding urging member 6 to the umbrella 5 is basically fixed to the umbrella 5 such as adhesion, welding, and sewing. However, if the detachable configuration is used, Replacement in case of damage is possible.

Next, the umbrella with the umbrella ground winding of Example 3 shown in FIG. 5 consists of a folding umbrella in which the handle shaft 1 and the main bone 2 can be expanded and contracted.
In the example of illustration, the winding biasing member 6 is being fixed below the folding point P of the main frame 2 of the folding umbrella.
Thereby, when the umbrella is closed, the lower half of the umbrella is wound and aligned (see FIG. 6).
Since other configurations are the same as those in the above embodiment, the description thereof is omitted.
Further, the winding biasing member 6 may be configured to be attached to the upper side beyond the folding point P.
In that case, the winding biasing member 6 may be separated at a position corresponding to the folding point P.
In the above-described embodiment, the folding folding umbrella is described, but the folding umbrella can also be applied to the folding umbrella according to the above configuration.

FIG. 8 shows a reference example which is not included in the technical scope of the present invention using the shape memory sheet base 6 ′ wound in a spiral shape.
In this case, the shape memory sheet 6 ′ is used by being woven as a part of the umbrella in the umbrella folding section from the middle fold A to the main bone 2.
That is, in the illustrated example, the shape memory sheet base 6 'extends from the base end side of the middle fold A to the midway position and extends to the tip of the middle fold A, similarly to the flat spiral winding spring. Not.
Other reference numerals are the same as those in the above embodiment, and the description thereof is omitted.

Further, the shape biasing member 6 may be integrally formed by overlapping the shape memory sheet base 6 ′ and an elastic body such as the flat plate spiral winding spring to enhance the restoring force.
In addition, it goes without saying that various design changes can be made without departing from the scope of the present invention.

It is the perspective view which looked at the opened state of the umbrella with an umbrella ground winding from the inside. Example 1 It is a perspective view of the state which started closing an umbrella. Example 1 It is a side view of the state which closed the umbrella completely. Example 1 It is the perspective view which looked at the opened state of the umbrella with an umbrella ground winding from the outside. (Example 2) It is the top view seen from the inner side of the state which opened the folding umbrella. (Example 3) It is a side view of the state which closed the folding umbrella. (Example 3) FIG. 2 is a front view of a flat spiral winding spring as an example of a winding urging member, in which (a) is a state in which an urging force is acting, and (b) is a straight line state against the urging force. . It is a perspective view of a reference example using shape memory sheet ground.
