ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a hair clip for retaining hairs between a pair of hair retainers pivoted by hinge portions.
2. Description of the Related Art
FIGS. 5 and 6
illustrate a hair clip B as a related art. The hair clip B includes a pair of hair retainers
51
,
52
each having a lever portions
51
b
,
52
b
at one end thereof. These hair retainers
51
,
52
are pivoted at one end portions and urged by a coil spring
56
so as to close the other end
51
a
,
52
a
of the hair retainers
51
,
52
.
Each hair retainer
51
(
52
) is provided with a pair of opposing hinge ledges
53
,
53
(
54
,
54
) at both lateral sides near the lever portion
51
b
(
52
b
). The pair of hinge ledges
53
,
53
of one of the hair retainers
51
are disposed outside the pair of hinge ledges
54
,
54
of the other of hair retainers
52
. These hinge ledges
53
,
53
,
54
,
54
are pivoted by a pivotal shaft
55
(i.e., a rivet) on which a coil spring
56
is wounded. Thus, the pair of hair retainers
51
,
52
are allowed to rotate, i.e., open and close, about the pivotal shaft
55
with the other end
51
a
,
52
a
of the hair retainers
51
,
52
urged in a closing direction.
Therefore, in a state that the hair clip is not in use, the hair retainers
51
,
52
are closed due to the spring force of the coil spring
56
. By gripping the lever portions
51
b
,
52
b
, the hair retainers
51
,
52
are opened so that hairs can be retained between the hair retainers
51
,
52
.
In the meantime, the corresponding hinge ledges
53
,
54
of the hair retainers
51
,
52
are disposed close to each other. However, a gap is usually formed between the adjacent hinge ledges
53
,
54
so that the hair retainers
51
,
52
can be freely opened and closed. As a result, there is the fear of unintentionally introducing hair into the gap, i.e., between the adjacent hinge ledges
53
,
54
.
Also, a gap is formed between the head portion
55
a
,
55
b
of the pivotal shaft
55
and the hinge ledge
53
,
53
located outside. Accordingly, hair may also be introduced unintentionally into the gap, i.e., between the head portion
55
a
,
55
b
and the hinge ledges
53
,
53
. In cases where the user's hairs are introduced into these gaps and caught therein, a few hairs may be pulled out of the user's head. This not only gives the pain to the user but also makes the user uncomfortable because of losing hair.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a hair clip which has no fear of introducing hair into a gap between adjacent hinge ledges of a pair of hair retainers.
It is another object of the present invention to proved a hair clip which has no fear of introducing hair into a gap between an enlarged head portion of a pivotal shaft and an outside hinge ledge.
According to a first aspect of the present invention, a hair clip includes:
a pair of hair retainers for retaining hair therebetween, each of the hair retainers having a first end portion and a second end portion;
a pivotal shaft for pivoting the pair of hair retainers at the first end portions; and
a spring for urging the second end portions of the pair of hair retainers in a closing direction thereof,
wherein each of the hair retainers includes a pair of opposing hinge ledges provided at the first end portion, the pair of opposing hinge ledges of one of the hair retainers being disposed adjacent to corresponding the pair of opposing hinge ledges of the other of the hair retainers, wherein the pivotal shaft is inserted into shaft receiving apertures formed in the hinge ledges so that the pair of hair retainers are pivoted about the pivotal shaft, and wherein one of the adjacent hinge ledges is provided with a hinge cover for covering an inside edge of the other of the adjacent hinge ledges along an inside edge of one of the adjacent hinge ledges, whereby hair is prevented from being introduced into a gap between the adjacent hinge ledges.
With this hair clip according to the first aspect of the present invention, since hair is prevented from being introduced into the gap between the adjacent hinge ledges, it is prevented that hair is caught by the adjacent hinge ledges and pulled out of a user's head when detaching the hair clip from the user's head. Thus, the hair clip does not make the user uncomfortable. Furthermore, since the hinge cover is provided along the inside edge of one of adjacent hinge ledges, the hinge ledges are strengthened, resulting in enhanced durability.
According to a second aspect of the present invention, a hair clip includes
a pair of hair retainers for retaining hair therebetween, each of the hair retainers having a first end portion and a second end portion;
a pivotal shaft for pivoting the pair of hair retainers at the first end portions; and
a spring for urging the second end portions of the pair of hair retainers in a closing direction thereof,
wherein each of the hair retainers includes a pair of opposing hinge ledges provided at the first end portion, the pair of opposing hinge ledges of one of the hair retainers being disposed adjacent to corresponding pair of opposing hinge ledges of the other of the hair retainers, wherein the pivotal shaft is inserted into shaft receiving apertures formed in the hinge ledges so that the pair of hair retainers are pivoted about the pivotal shaft, wherein one of the adjacent hinge ledges disposed outside is provided with an outwardly protruded cylindrical portion, and wherein an enlarged head portion of the pivotal shaft is disposed in the cylindrical portion, whereby hair is prevented from being introduced into a gap between the enlarged head portion and the one of the adjacent ledges disposed outside.
With this hair clip according to the second aspect of the present invention, since hair is prevented from being introduced into a gap between the enlarged head portion of the pivotal shaft and the outside hinge ledge, it is prevented that hair is caught by the enlarged head portion and the outside hinge ledge when detaching the hair clip from the user's head. Thus, the hair clip does not make the user uncomfortable. Furthermore, since the hinge cover is provided along the inside edge of one of adjacent hinge ledges, the hinge ledges are strengthened, resulting in enhanced durability.
According to a third aspect of the present invention, a hair clip includes:
a pair of hair retainers for retaining hair therebetween, each of the hair retainers having a first end portion and a second end portion and having a lever portion at the first end portion;
a pivotal shaft for pivoting the pair of hair retainers at the first end portions; and
a coil spring wounded around the pivotal shaft for urging the second end portions of the pair of hair retainers in a closing direction thereof,
wherein each of the hair retainers includes a pair of opposing hinge ledges extending from lateral edges of the first end portion, the pair of opposing hinge ledges of one of the hair retainers being disposed adjacent to corresponding pair of opposing hinge ledges of the other of the hair retainers, wherein the pivotal shaft is inserted into shaft receiving apertures formed in the hinge ledges so that the pair of hair retainers are pivoted about the pivotal shaft, wherein one of the adjacent hinge ledges is provided with a hinge cover for covering an inside edge of the other of the adjacent hinge ledges along an inside edge of the one of the adjacent hinge ledges, whereby hair is prevented from being introduced into a gap between the adjacent hinge ledges, wherein one of the adjacent hinge ledges disposed outside is provided with an outwardly protruded cylindrical portion, and wherein an enlarged head portion of the pivotal shaft is disposed in the cylindrical portion, whereby hair is prevented from being introduced into a gap between the enlarged head portion and the one of the adjacent ledged disposed outside.
