Hair iron
The present invention relates to a hair iron including: one pair of bodies rotatably hinged to each other; heat plates disposed on the bodies; and supporting means, each being disposed between one of the bodies and one of the heat plates in such a manner as to support the longitudinal center of each heat plate. Accordingly, each supporting means is disposed between each body and each heat plate to support the longitudinal center of each heat plate, so that the pair of heat plates is evenly contacted with each other according to the seesaw principle, thereby allowing the heat and pressure generated from the heat plate to be applied uniformly to hair.
1. A hair iron comprising:
one pair of bodies rotatably hinged to each other;
a heat plate disposed on one of the bodies;
a supporting member, the supporting member being disposed between the one of the bodies and the heat plate in such a manner as to support a longitudinal center of the heat plate; and
a horizontal support rod;
wherein the heat plate comprises:
an accommodating portion into which the horizontal support rod is inserted longitudinally; and
an open portion formed at a bottom part of the accommodating portion; and
wherein the horizontal support rod has a suspended portion suspended on both sides of the open portion;
the heat plate and the horizontal support rod are supported by the supporting member at the same time;
the horizontal support rod has a first end and a second end; a pressure exceeding prevention barrier is mounted on each of the first and second ends, the pressure exceeding prevention barriers have a height that is the same as a top surface of the heat plate; and,
the one of the bodies has a locking protrusion to support the horizontal support rod and to prevent the horizontal support rod from being escaped from the one of the bodies;
wherein each body comprises: a lead screw rotatably mounted thereon; an adjuster fixed on the lead screw and the adjuster protruding from the body; a pair of nuts connected around the lead screw, the pair of nuts separated by a distance from each other; and a plate spring disposed and bulging upwardly between the pair of nuts to support the bottom of the supporting member; wherein the pair of nuts move in a direction approaching each other or in a direction departing from each other in accordance with the forward or reverse rotation of the adjustor so as to deform the plate spring.
2. The hair iron according to claim 1 , wherein the supporting member comprises an elastic member disposed between the one of the bodies and the heat plate.
3. The hair iron according to claim 1 , wherein the supporting member comprises a compression spring disposed between the one of the bodies and the heat plate.
4. The hair iron according to claim 1 , wherein the open portion has a reduced width than the bottom part of accommodating portion.
5. The hair iron according to claim 1 , wherein each body has an elongated hole formed thereon, and each heat plate has an insertion part formed thereon in such a manner as to be inserted into the elongated hole.
6. A hair iron comprising:
a pair of bodies rotatably hinged to each other;
a heat plate disposed on one of the bodies;
a cover disposed between the heat plate and the one of the bodies to cover the heat plate;
buffering members interposed between the cover and the heat plate, the buffering members supporting the heat plate;
a supporting member being disposed at a longitudinal center of the cover, the supporting member including a protrusion protruding from the one of the bodies toward the cover or from the cover toward the one of the bodies; and
pressure exceeding prevention barriers provided on both ends of the cover, wherein a height of the prevention barriers are the same as a height of a top surface of the heat plate;
wherein each body comprises: a lead screw rotatably mounted thereon; an adjuster fixed on the lead screw and protruding from the body; a pair of nuts connected around the lead screw, the pair of nuts separated by a distance from each other and fitted on the lead screw in such a manner as to be moved in a direction approaching each other or in a direction departing from each other in accordance with the forward or reverse rotation of the adjustor; a plate spring disposed between the pair of nuts, and bulging upwardly to support the support the bottom of the supporting member; wherein the pair of nuts move in a direction approaching each other or in a direction departing from each other in accordance with a forward or reverse rotation of the adjustor to deform the plate spring.
7. The hair iron according to claim 6 , wherein the supporting member is formed of a semi-circular protruding portion protruded from the body toward the cover.
8. The hair iron according to claim 6 , wherein each body has an elongated hole formed thereon, and each heat plate has an insertion part formed thereon in such a manner as to be inserted into the elongated hole.
