Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of an umbrella capable of walking safely by confirming the view ahead.

[0002]

[Prior art]

 Conventionally, in order to confirm the field of view in front of the umbrella, there has been proposed an umbrella cover in which a part of the fabric has a transparent structure (for example, Japanese Utility Model Laid-open No. 60-20716, Japanese Utility Model No. 61-1002119, Japanese Utility Model No. 4-79518). The transparent material sheet is made of acrylic resin or vinyl.

[0003]

[Problems to be solved by the invention]

 As a result, the transparent material sheet may become fogged due to rapid changes in humidity and temperature, and the visibility may not be effective. In addition, if used for a long period of time, the transparency of the vinyl decreases, and in addition, scratches and other damage are caused by contact and rubbing of other parts, which also makes the outlook worse. In the umbrella structure of Japanese Utility Model Laid-Open No. 4-79518, in which only the area between the umbrella skeletons is transparent, two sheets, a transparent material sheet piece and other material sheet pieces, must be attached to the entire umbrella skeleton. No. In terms of manufacturing, it is relatively easy to attach a cloth or the like that will become a single material sheet, but if two or more material sheets are attached between only one skeleton, the work is complicated. Will be.

On the other hand, a structure in which a single material sheet piece is attached to ensure workability as in the related art may be employed. To achieve such a structure, a transparent vinyl or acrylic resin sheet is used. On the other hand, there is a drawback in that it is necessary to apply a predetermined color to a portion which is not to be made transparent and to make it opaque so that it is troublesome. The purpose of the present invention is to be able to always see the front well without any deterioration of the front view due to aging, scratches, etc., as well as the effects of humidity and temperature changes. Another object of the present invention is to provide a perforated umbrella that can be made by a simpler operation than providing a transparent part.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a perforated umbrella according to the present invention, when the umbrella is deployed, provides a plurality of holes near the periphery of the upholstery portion formed between the umbrella skeletons, and the peripheral edge of the hole is a sewing machine. An eye is formed so that the plurality of holes can be seen from the front. A plurality of holes formed in the upholstery portion are formed in one or more rows in a direction perpendicular to the skeleton. The plurality of holes are provided so as to straddle two upholstery portions sandwiching one skeleton.

[0006]

[Action]

 According to the above configuration, the front can always be reliably seen through, and the manufacturing process is not more complicated than providing a transparent portion such as a vinyl sheet.

[0007]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a perforated umbrella according to the present invention. The material sheet serving as the cover of the umbrella 1 uses the cloth 3, and the upholstery portion formed between the respective skeletons is used as the upholstery fabric portion. In the vicinity of the peripheral portion 3b of the upholstery portion 3a between the skeletons 1a and 1b, three rows of holes 2 each having a size of 10 yen coin are formed. Note that an opaque synthetic resin sheet or the like may be used as the material sheet.

FIG. 2 shows an enlarged view of the plurality of holes of FIG. Three holes 2a, 2b and 2c are formed along the center line 4a. Four holes 2d, 2e, 2f and 2g are formed along the center line 4b. Five holes 2h, 2i, 2j, 2k and 21 are formed along the center line 4c. When the umbrella is unfolded, in order to maintain the tensile strength of the upholstery fabric portion 3a, the upholstery fabric portion 3a formed between the skeletons 1a and 1b is placed between the first, second, and third rows. Has no holes. Each hole is opened by a press jig or the like, and a perforation 7 is formed in a peripheral portion of each hole as shown in an enlarged view of the hole 2a to strengthen the peripheral portion. In the manufacturing process, the process of forming a plurality of holes in one piece of cloth by pressing and making perforations is added, and the manufacturing process is simpler than in the case of partially transparent using vinyl or the like.

FIG. 3 is a diagram illustrating a use state of the perforated umbrella according to the present invention. It is cut and shown at a portion of the cloth 3 serving as a cover of the umbrella 1 having holes. When riding a bicycle, walking fast, or blowing wind from the front, the umbrella 1 is inclined forward as shown in FIG. At this time, bring the opened part of the cloth 3 of the umbrella 1 forward. An umbrella holder (hereinafter, referred to as “user”) 7 can see ahead through a number of holes 2. If twelve holes having a size of about 10 yen coins are formed at regular intervals around the upholstery cloth portion 3a in FIG. 1, a sufficient field of view can be secured.

The rain will fall obliquely as indicated by 8 in FIG. In addition, the tangent 9 of the surface having the hole for tilting the umbrella has an angle close to vertical. Therefore, the angle θ between the direction in which rain falls and the surface of the hole is a very small acute angle, and the amount of rain entering the hole is small. Also, even if rain enters the hole, the user 7 hardly gets wet by the leaked rain. Next, the rain falling on the umbrella upholstery fabric flows down toward the surrounding area. When the rain falls to the upper side of the hole, it flows along the periphery of the hole, so it does not fall into the hole. This is shown in FIG.

FIGS. 4B and 4C are diagrams for explaining how an object entering the field of view is seen. (B) is a diagram when the user focuses on the hole of the umbrella. (C) is a case where a distant object (car) 5 is focused. When looking ahead, the user 7 can clearly see the car 5 in the real field of view 6 as shown in FIG. In addition, since the transparent material sheet is used without passing through, it is possible to solve the drawbacks of the conventional transparent sheet that the movement of the object cannot be quickly grasped due to obscurity due to scratches, aging, and fogging. Since the object is clear, the movement of the object can be detected quickly.

FIG. 5 is a perspective view showing a second embodiment of a perforated umbrella according to the present invention. Holes 13a and 13b are formed in the peripheral corners of the upholstery portions 11 and 12 on both sides of the umbrella skeleton 10, respectively. The holes 13a and 13b are larger than the hole 2 shown in FIG. If the holes are made larger, the number of holes can be reduced, and if they are provided near the skeleton, the reduction in the tensile strength of the cloth due to the holes can be minimized. A clear view can always be ensured, and the effects and manufacturing steps are the same as those in FIG.

FIG. 6 is a perspective view showing a third embodiment of a perforated umbrella according to the present invention. Holes 16a, 16b, 16c and 16d are formed in the periphery of the upholstery portion 17 between the umbrella frameworks 14 and 15. Holes 16c and 16d are smaller in diameter than holes 16a and 16b. The effects and manufacturing steps are the same as those in FIG.

FIG. 7 is a perspective view showing a fourth embodiment of a perforated umbrella according to the present invention. Holes 21a and 21b are formed in the periphery of the upholstery portion 20 between the umbrella skeletons 18 and 19. Holes 21a and 21b have the same diameter as holes 13a and 13b. The effects and manufacturing steps are the same as those in FIG.

FIG. 8 is a perspective view of a perforated umbrella according to a fifth embodiment of the present invention. Holes 25a, 25b and 25c, 25d are formed at the peripheral corners of the upholstery portions 23 and 24 on both sides of the umbrella skeleton 22, respectively. The holes 25a and 25c are larger than the holes 2 shown in FIG. Holes 25b and 25d are smaller than holes 25a and 25c. If it is provided near the skeleton, it is possible to minimize the decrease in the tensile strength of the cloth due to the opening. A clear view can always be ensured, and the effects and manufacturing steps are the same as those in FIG.

[0016]

[Effect of the invention]

 As described above, in the present invention, a plurality of holes are provided in the vicinity of the periphery of the stretched fabric of the deployed umbrella. This ensures that vision is not obscured due to scratches, aging, or clouding, and that you can see clearly ahead in any situation. Further, since a predetermined visibility is ensured by providing a plurality of small holes, a decrease in the tensile strength of the upholstery fabric when the umbrella is opened can be minimized. When looking ahead from the inside of the umbrella, the object can be focused by the ability to correct the focus of the eye, so that a field of view without borders between the holes can be obtained. Therefore, safe walking becomes possible. In addition, rain hardly enters from the hole.
