BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a hair curler for rolling to curl a strand of hair.
2. Background Art
A prior-art hair curler, as disclosed in Japanese Utility Model Publication No. Hei 5-16961, as shown in FIG. 37-FIG. 39, has a roller 1 and a rectangular setting frame 4 having a pair of clasps 2, 2 for holding the roller 1 radially from both sides and a pair of connecting portions 3, 3 connecting the ends of the clasps 2, 2 with each other; the setting frame 4 is releasably engaged with both ends in an axial direction of the roller 1 through the pair of connecting portions 3, 3; and a cover 5 for covering about a half of the outer periphery of the roller 1 between the clasps 2, 2. In this case, the setting frame 4 is produced of a synthetic resin, while the cover 5 is produced of a net-like flexible material of knitted yarn, and therefore both ends 5A, 5A of the cover 5 are fixedly embedded by insert molding in the pair of clasps 2, 2 of the setting frame 4. In this case, both ends of the cover 5 easily bends to change the bending direction of the cover, that is, either side of the cover 5 is usable on the roller 1 side. The hair curler, therefore, can be handled very easily when a strand of hair is rolled on the roller 1.
Another prior-art hair curler, as shown in FIGS. 40 and 41, has a roller 1 and a setting frame 4 including a pair of clasps 2, 2 for holding the roller 1 radially from both sides, and a rectangular setting frame 4 having a pair of connecting portions 3, 3 for connecting the ends of the clasps 2, 2 with each other, a central holding portion 7 provided at center between the pair of clasps of the setting frame 4, and a pair of circular connecting pieces 8, 8 provided for connecting both ends of the central holding portion 7 to both ends of the pair of clasps 2, 2; the pair of clasps 2, 2, the pair of connecting portions 3, 3, the central holding portion 7 and the connecting pieces 8, 8 of the setting frame 4 being formed of a synthetic resin in one body.
The former, however, has the following problem that since the setting frame 3 is produced of a synthetic resin while the cover 5 is of a net-like flexible material of knitted yarn, both ends 5A, 5A of the cover 5 must be fixedly embedded by insert molding in the pair of clasps 2, 2 of the setting frame 4, making the insert molding process very troublesome and the manufacturing process complicated.
Also the cover 5, produced of a net-like flexible material of knitted yarn, deflects as indicated by a chain line in FIGS. 37 to 39 when used, deteriorating in shape retention, whereby the hair curler will fail to hold the hair well in between the cover 5 and the roller 1; that is, the rolled state of the hair on the roller 1 can not securely be maintained.
In the case of the latter, since the setting frame 3 can easily be manufactured of a synthetic resin but there is left a large space between the pair of clasps 2, 2 and the central holding portion 7, a strand of hair rolled on the roller 1 is clasped insufficiently; that is, the rolled state of the hair on the roller 1 can not securely be held. Furthermore, in this case, the connecting pieces 8, 8, having no flexibility, can not be curved to the reverse side as indicated by a chain line in FIG. 41. The hair curler, therefore, is hard to handle when rolling a strand of hair on the roller 1.
In view of the above-described various problems inherent to the heretofore known arts, it is an object of the present invention to provide a hair curler which facilitates the manufacture and assembling of the setting frame and the cover, is easy to handle, and can clasp the hair well between the cover and the roller.
SUMMARY OF THE INVENTION
In the hair curler of the present invention which has a roller 11, and a rectangular setting frame 19 including a pair of clasps 20, 20 for holding the roller 11 radially from both sides and a pair of connecting portions 21 and 22 for connecting the pair of clasps 20, 20 for holding the roller 11 radially from b
