Description

The present invention relates to an umbrella, and more particularly to a dew point of the umbrella.

A normal umbrella consists of a middle rod, an upper wheel fixed to one end of the middle rod, a lower wheel that can move along the middle bar, and multiple umbrella bones that are pivotally supported by the upper wheel and the lower wheel. It is equipped with an umbrella cloth supported by a plurality of umbrella bones. A dew tip is attached to the end of each umbrella bone, and the umbrella cloth is connected to the umbrella bone via the dew tip. The conventional dew tip is a columnar body that extends in the axial direction and has an umbrella bone hole for accommodating the end of the umbrella bone and a thread hole for penetrating the thread. When fixing such a dew tip to the umbrella cloth, the dew tip must be manually sewn to the umbrella cloth and fixed.

Patent Document 1 discloses a kind of dew destination. In addition to having the above-mentioned umbrella bone hole and thread hole, the dew point has an elastic portion extending from the peripheral edge of the umbrella bone hole along the umbrella bone and an elastic portion at the end of the elastic portion orthogonal to the extension direction of the elastic portion. It is further provided with a claw portion formed so as to extend in the direction in which the bone is formed. Further, the umbrella bone corresponding to the dew tip is formed with a fixing hole into which the claw portion can be inserted. By inserting the claw portion into the fixing hole and storing it, the dew tip is localized on the umbrella bone, and the shaking of the dew tip with respect to the umbrella bone can be suppressed. Further, the dew tip is fixed to the umbrella cloth by the method described above.

However, such a method of fixing the umbrella cloth and the dew cloth has a low manufacturing efficiency of the umbrella, and a large number of steps are required to fix the dew cloth and the umbrella cloth, so that the manufacturing cost is high.

Therefore, an object of the present invention is to provide a dew point that can improve the manufacturing efficiency of an umbrella.

As a means for achieving the above object, the present invention provides the following dew destinations.

The dew destination of the present invention is
An inner peripheral surface that is a dew point connecting the umbrella bone and the umbrella cloth and defines an accommodation hole in which the tip of the umbrella bone is accommodated, and an outer peripheral surface located on the opposite side of the inner peripheral surface. An extension having a main body and an end portion connected to the outer peripheral surface and an end portion located on the opposite side of the connection end portion while extending outward from the main body, and the umbrella cloth is fixed. It is characterized by having a part and.

According to the above configuration, the dew tip according to the present invention can be fixed to the umbrella cloth by applying, for example, an adhesive to the stretched portion instead of sewing, and the manufacturing efficiency of the umbrella has been improved conventionally. Can be improved.

Therefore, the present invention can provide a dew point capable of improving the manufacturing efficiency of the umbrella by the above-described configuration.

It is sectional drawing which shows the cross section along the axis of the embodiment. It is a top view which shows the embodiment. It is sectional drawing which shows the cross section orthogonal to the axis of the embodiment.

Hereinafter, embodiments of the dew destination according to the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the front surface of one embodiment of the dew destination according to the present invention, FIG. 2 is a perspective view showing the back surface of the present embodiment, and FIG. 3 is along the axis of the present embodiment. It is sectional drawing which shows the cross section.

As shown in FIGS. 1, 2 and 3, the embodiment of the dew point 10 according to the present invention is used to connect the umbrella bone 1 and the umbrella cloth 2, and is along a predetermined axis L. A main body 11 which is a hollow columnar body extending from the inner end 111 to the outer end 112 and surrounding the accommodating hole 113 in which the tip end portion of the umbrella bone 1 is accommodated, and two extending portions 12 extending outward from the main body 11. The cap 13 is arranged at the outer end 112 of the main body 11 and is formed in a spherical shape.

The main body 11 has an inner peripheral surface 114 that defines the accommodating hole 113, and an outer peripheral surface 115 located on the opposite side of the inner peripheral surface 114. The outer peripheral surface 115 has a flat surface portion 116 extending from the inner end 111 to the outer end 112, an arc portion 117 extending from the inner end 111 to the outer end 112, and a flat surface portion extending from the inner end 111 to the outer end 112. It has two intermediate portions 118, which connect the 116 and the arc portion 117.

The two extending portions 12 extend outward from the two intermediate portions 118 of the outer peripheral surface 115, respectively. Each extension portion 12 connects the connection end portion 121 connected to the intermediate portion 118, the end portion 122 located on the opposite side of the connection end portion 121, and the connection end portion 121 and the end portion 122, and is connected to the main body 11. An upper end edge 123 facing the inner end 111 side, a lower end edge 124 located on the opposite side of the upper end edge 123, and a back surface 126 extending from the connecting end portion 121 to the end portion 122 and facing the arc portion 117. It has a joint surface 125 located on the opposite side of the back surface 126. Further, in order to stabilize the stretched portion 12, the stretched portion 12 further has a reinforcing portion 127 that fills a gap between the back surface 126 and the outer peripheral surface 115. The umbrella cloth 2 may be fixed by being adhered to the joint surface 125 of the stretched portion 12 with an adhesive, for example, a hot melt adhesive, or may be fixed by welding. In the case of welding, for example, the umbrella cloth 2 and the joint surface 125 of the stretched portion 12 are heated and melted by ultrasonic waves or high frequencies, and the dew point 10 is pressed against the umbrella cloth 2 to be integrated and fixed.

FIG. 4 is a plan view showing the present embodiment. As shown in FIGS. 3 and 4, the lower end edges 124 of each of the two stretched portions 12 are oblique toward the inner end 111 side according to the shape of the umbrella cloth 2 fixed to the stretched portion 12. It is formed so as to extend to.

FIG. 5 is a cross-sectional view showing a cross section orthogonal to the axis L of the present embodiment. As shown in FIGS. 4 and 5, the joint surface 125 of the stretched portion 12 is continuous with the flat surface portion 116 of the main body 11 and is on the same plane as the flat surface portion 116. As a result, when the umbrella cloth 2 is fixed to the joint surface 125 of the stretched portion 12, the flat surface portion 116 comes into contact with the umbrella cloth 2, so that the dew point 10 can be stably localized on the umbrella cloth 2. Further, when the joint surface 125 and the flat surface portion 116 are in contact with the umbrella cloth 2 at the same time, the dew point 10 can be easily fixed to the umbrella cloth 2 by welding or an adhesive.

As described above, the dew point 10 according to the present invention is stably fixed to the umbrella cloth 2 by welding or adhesive instead of sewing by hand. Since the work is easier than the conventional fixing method and the number of steps required is reduced, the manufacturing efficiency of the umbrella can be improved and the manufacturing cost can be lowered.
Although preferred embodiments and variations of the present invention have been described above, the present invention is not limited thereto, and all modifications and equivalents are made as various configurations included in the spirit and scope of the broadest interpretation. It shall include the composition.

Since the dew point according to the present invention can improve the manufacturing efficiency of an umbrella, it can be applied to an umbrella in various ways.
