Description

  The present invention relates to umbrella-like structures such as rain umbrellas, parasols, Japanese umbrellas, sun umbrellas such as beach umbrellas and garden umbrellas.

  When the umbrella is closed, the part stretched between the main bones of the umbrella cloth sags and spreads out. For this reason, the slack portion is wound around the outer side of the umbrella shaft and bundled, and is further stopped with a winding string. Since this series of operations is performed by hand, if the umbrella cloth is wet by use on a rainy day, the hand gets wet. As an umbrella for eliminating the annoyance that the hands get wet, for example, there is one disclosed in Citation 1.

  This umbrella is shown in FIGS. The umbrella cloth 101 is provided with a plurality of elastic bending members 102. In the state in which the umbrella 100 is opened, the bending members 102 are elastically deformed into a flat shape because the radially arranged master bones 103 stretch the umbrella cloth 101. In this state, when the umbrella 100 is closed, the tension of the umbrella cloth 101 by the main bone 103 is loosened, so that the bending member 102 is bent, and the slack portion 101 a between the main bone 103 and the main bone 103 of the umbrella cloth 101 is placed outside the umbrella shaft 104. Wrap around. Then, the slack portion 101a can be prevented from spreading by winding the wound string 105 around the slack portion 101a.

JP 2000-312609 A

However, in the umbrella 100 described above, since the slack portion 101a of the umbrella cloth 101 is wound around the umbrella shaft 104, the wet portion of the umbrella cloth 101 is exposed. Therefore, there is a possibility that the user's hand and clothes of the umbrella 100 may get wet.
The present invention has been made to solve such a problem, and an object of the present invention is to provide an umbrella-like structure that can hide a portion stretched between the main bones of the umbrella cloth by closing the umbrella-like structure. To do.

  Next, an example of an embodiment of an umbrella-like structure according to the present invention will be described with reference to the drawings. Examples of the umbrella-like structure include a rain umbrella, a parasol, a Japanese umbrella, a sun umbrella such as a beach umbrella and a garden umbrella, and the like in this embodiment. However, it is not limited to an umbrella.

  1 to 7 show an umbrella 1 according to the present invention. The umbrella 1 is provided with a plurality of main bones 3, a plurality of receiving bones 8, and a ladle 11. When the user moves the armor 11 toward the stone protrusion 9 along the umbrella shaft 5 from the state in which the umbrella shown in FIG. 1C is closed, the receiving bone 8 pushes up the main bone 3. Thereby, the main bone 3 spreads radially. That is, the umbrella 1 is opened (FIG. 1A). Then, when the user moves the armor 11 to the hand 15 side along the umbrella shaft 5 from the state in which the umbrella 1 is opened, the receiving bone 8 pulls the main bone 3 toward the umbrella shaft 5 side. That is, the umbrella 1 is closed.

  Further, the umbrella 1 is connected to the core material 4 provided on the portion 2 a stretched between the main bones 3 of the umbrella cloth 2, the core material 4 and the umbrella shaft 5, or the core material 4 of the umbrella cloth 2 is provided. The portion 2b and the umbrella shaft 5 are connected to each other, and the stretched portion 2a of the umbrella cloth 2 is pulled toward the umbrella shaft 5 as the main bone 3 is pulled toward the umbrella shaft 5 and the tension of the umbrella cloth 2 is loosened. A tension member 6.

  As shown in FIG. 2, one core member 4 is provided between each parent bone 3. The core material 4 has a linear shape or a rod shape, and is formed of, for example, resin or metal. The core material 4 is provided at a position equidistant from the two adjacent main bones 3.

  The length of the core member 4 is such that when the umbrella 1 is closed, the portion 2a stretched between the main bones 3 of the umbrella cloth 2 can be moved to the umbrella shaft 5 side. In the present embodiment, as shown in FIG. 3, the length of the core material 4 is set so as to reach from the vicinity of the outer peripheral edge 2 c of the umbrella cloth 2 to the vicinity of the umbrella shaft 5. Although a wide range from the vicinity of the center of the cloth 2 to the vicinity of the outer peripheral edge 2c can be moved to the umbrella shaft 5 side by the core material 4, it does not necessarily have to be made so long.

As shown in FIG. 4 (A), the core material 4 is provided on the inner side surface 2d of the umbrella cloth 2, and is not easily noticeable by others when the umbrella 1 is opened. However, the core material 4 may be provided on the outer surface 2e of the umbrella cloth 2 as shown in FIG. 4 (B), or on both the inner surface 2d and the outer surface 2e as shown in FIG. 4 (C). It may be provided. The core material 4 can be used as a part of the design. When the core material 4 is provided on the inner side surface 2d of the umbrella cloth 2, the core material 4 is designed for the inner side surface 2d of the umbrella cloth 2. When the core material 4 is provided on the outer surface 2e of the umbrella cloth 2, the core material 4 can be used as a part of the design of the outer surface 2e of the umbrella cloth 2.
The core material 4 is bonded to the umbrella cloth 2 using, for example, an adhesive. However, the means for fixing the core material 4 to the umbrella cloth 2 is not limited to this.

  One end 6 a of the tension member 6 is formed on the core material 4 when the core material 4 is bonded to the inner side surface 2 d of the umbrella cloth 2 (FIGS. 4A and 4C). When it is bonded only to the outer side surface 2e (FIG. 4B), it is connected to the part 2b of the umbrella cloth 2 where the core material 4 is provided. The other end 6 b of the pulling member 6 is connected to a connecting member 7 fixed to the umbrella shaft 5.

  As shown in FIG. 1A, the pulling member 6 is stored in the inner space 12 on the side of the stone protrusion 9 with respect to the receiving bone 8 in a state where the umbrella 1 is opened. By doing in this way, when using the umbrella 1, it can prevent that the tension | pulling member 6 obstructs a user.

  As the pulling member 6, a string-like member having elasticity such as a rubber string is used. However, in place of the elastic string-like member, for example, a spring may be used, or a combination of a non-elastic string or wire linear member and an elastic rubber string or spring is used. You may do it. Moreover, if the part 2a on which the umbrella cloth 2 is stretched can be pulled toward the umbrella shaft 5 when the umbrella 1 is closed, the tension member 6 is not a stretchable string or a string-like member or wire such as a wire. A shaped member may be used.

  As shown in FIG. 1C, each of the main bones 3 is curved so that the tip 13 side is closer to the umbrella shaft 5 than the central portion 3a in a state where the umbrella 1 is closed. Therefore, the entire umbrella 1 can be collected more finely with the umbrella 1 closed.

  The umbrella 1 includes a sheet-like spring member 14 that urges a portion 2a on which the umbrella cloth 2 is stretched toward the umbrella shaft 5 side. In the present embodiment, a sheet-like spring member 14 is provided in the vicinity of the tip 13 of the umbrella cloth 2. The spring member 14 is made of, for example, a resin or metal sheet.

  5 and 6 show the spring member 14. The spring member 14 has a shape in which the blade portions 14a and 14b are widened to the left and right, and is bent at the center portion 14c when no external force is applied. The left and right blade portions 14a and 14b are bonded to the umbrella cloth 2 using, for example, an adhesive. Although the spring member 14 of the present embodiment is bonded to the inner side surface 2d of the umbrella cloth 2, it may be bonded to the outer side surface 2e of the umbrella cloth 2. Further, although the spring member 14 of the present embodiment is bonded in the vicinity of the tip 13, the bonding position is not limited to the vicinity of the tip 13. The spring force of the spring member 14 is not so strong, and the angle at which it is bent at the central portion 14c changes according to the change in the tension of the umbrella cloth 2 as the umbrella 1 is opened and closed.

  By providing the spring member 14, when the umbrella 1 is closed, if the tension of the umbrella cloth 2 by the main bone 3 is loosened, the portion 2a on which the umbrella cloth 2 is tensioned can be set to move toward the umbrella shaft 5. That is, when closing the umbrella 1, the spring member 14 can assist the pulling member 6 to draw the portion 2 a on which the umbrella cloth 2 is stretched toward the umbrella shaft 5 side.

  When closing the used umbrella 1, when the tension of the umbrella cloth 2 by the main bone 3 is loosened, the portion 2 a to which the umbrella cloth 2 is stretched is drawn toward the umbrella shaft 5 by the pulling member 6. Therefore, the umbrella 1 can be closed while the portion 2a on which the umbrella cloth 2 is stretched is drawn inward. In addition, since the spring member 14 is provided in the present embodiment, the spring member 14 can assist the pulling member 6 to draw the portion 2a on which the umbrella cloth 2 is stretched toward the umbrella shaft 5 side. Therefore, the umbrella 1 can be closed while pulling the portion 2a on which the umbrella cloth 2 is stretched better inside.

As described above, when the umbrella 1 is closed, the portion 2a on which the umbrella cloth 2 is stretched is automatically drawn to the umbrella shaft 5 side, so that it is necessary for the user to handle the portion 2a on which the umbrella cloth 2 is stretched by hand. Absent. Therefore, the user's hand is not wetted.
Further, when closing the umbrella 1, the portion 2a on which the umbrella cloth 2 is stretched can be drawn into the umbrella shaft 5 side and hidden. For this reason, it is possible to hide a wet part due to rain, and it is possible to prevent the user's hand or clothes from getting wet.

In addition, since the portion 2a on which the umbrella cloth 2 is stretched can be hidden while the umbrella 1 is closed, the appearance can be refreshed, and the umbrella 1 having a new design that has never been seen can be provided.
Further, when the umbrella 1 is closed, the portion 2a on which the umbrella cloth 2 is stretched can be pulled into the umbrella shaft 5 side, so that it is not necessary to stop the umbrella cloth 2 with the winding string after the umbrella 1 is closed. It can be made unnecessary. And since it can make a winding string unnecessary, it can be made clear and the rain umbrella 1 of the new design which has never existed from this point can be provided.

In addition, although the above-mentioned umbrella 1 provided the spring member 14, the spring member 14 does not need to be provided.
Moreover, although the above-mentioned umbrella 1 curved the main bone 3, it is not necessary to curve the main bone 3.

  INDUSTRIAL APPLICABILITY The present invention can be used for umbrella structures such as rain umbrellas, parasols, Japanese umbrellas, sun umbrellas such as beach umbrellas and garden umbrellas.
