Description
This invention relates to a hair curler heater and particularly to
a portable hair curler heater.
A primary object of this invention is to provide a hair curler
heater of the construction in which, when the hair curler heater is
in use, heating rods for heating hair curler bobbins are brought to
upright positions and when not in use, are brought down to be
received into a container, thereby to make the container
substantially small in thickness so as to be convenient for
carrying and easy handling. In order to achieve the objective, a
heating board having heating rods attached thereto is pivotally
mounted in the container. Means are provided to rotate the heating
board in response to opening of the lid so as to raise the heating
rods to a generally vertical position. Rotation of the heating
board in response to closing of the lid moves the heating rods down
to a generally horizontal position. This arrangement permits the
container to be made relatively thin, somewhat greater than the
diameter of a curler, and still be able to house a large number of
curlers. The hair curler bobbins can be left attached to the
heating rolls during the time the rods are stored in the container.
The container is provided therein with a space to receive the
heating board with curler bobbins when the heating board is rotated
in such a state as to bring down the heating rods to the
substantially horizontal position.
As should be apparent, the heater is simple to operate. The
operation of opening the lid raises each heating rod with each hair
curler bobbin kept attached thereto in a state ready for use. The
operation of closing the lid moves the heating board and each
heating rod down with each heating hair curler bobbin kept attached
thereto to be received in the container. This arrangement makes the
hair curler heater very easy to handle and eliminates possibility
of mistaken handling since, when the curlers are in an upright
position, the user knows that they will be heated.
In order to effect the operation described above, this invention is
provided with a link mechanism for rotating the heating board upon
opening and closing of the container lid.
Another object of the invention is to provide a mechanism by which
to automatically open a switch means for the electric circuit of
the heating element adapted to heat the heating board, when the lid
of the container is closed, and the heating board together with the
heating rods are brought down and received in the container, and by
which to automatically close said switch means when the lid is
opened to raise up the heating rods to place the hair curlers in a
position for use. Provision of such a switch means makes it
possible to do away with manual operation of a switch means and to
eliminate the possibility of current flowing through the heating
board when the hair curler heater is not in use.
According to the invention, the container also is provided therein
with recesses in side-by-side relation to receive therein the
heating rods with the hair curler bobbins being attached when the
heating rods are brought down. These recesses are of the same
general shape as the outer shapes of the hair curler bobbins. The
container is further provided therein with suitably shaped recesses
for reserve hair curler bobbins to receive the reserve hair curler
bobbins in a generally horizontal position. A partition wall is
provided between the recesses for receiving the reserve hair curler
bobbins and the recesses for the hair curler bobbins left fitted
over the heating rods. This structure precludes the possibility,
when the container is closed, of the hair curler bobbins being
removed or falling off from the heating rods even if the container
falls down or is placed or carried in any position. It also makes
it possible for the container to securely receive therein a large
number of reserve hair curler bobbins.
A detailed description of the invention follows with reference to
the accompanying drawings in which:
FIG. 1 is a perspective view of the container with its lid open
according to a preferred embodiment of this invention;
FIG. 2 is a perspective view similar to FIG. 1 but showing the
container with its lid half closed;
FIG. 3 is a fragmentary view, partly broken and in section, of FIG.
1;
FIG. 4 is a fragmentary view, partly broken and in section, of FIG.
2;
FIG. 5 is a fragmentary view, partly in section, of the container
of FIG. 1 but showing the container with its lid closed; and
FIG. 6 is an exploded view illustrative of a link mechanism for the
heating board of the container shown in FIG. 1 and a depressing
member adapted to operate said link mechanism.
In FIGS. 1 and 2 of the drawings, the numeral 1 designates a
plastic container; 2 an outer frame of the plastic container 1
which is on top of the container bottom wall; 3 a lid of the
plastic container 1; 3' a mirror attached to the inside of lid 3;
and 4 designates a handle attached to the front of the outer frame
2. The upper lid 3, as will be presently described with reference
to FIG. 6, is connected to the back side of outer frame 2 so as to
be freely opened and closed. The numeral 5 designates a heating
board, which, as will later be described, is pivotally supported by
the outer frame 2 of the container and contains therein a heating
element, such as for example electric resistance 6, which is
insulated from the top of the board. The numeral 7 designates metal
heating rods, a suitable number of which are mounted in spaced
relationship on the heating board 5. The numeral 8 designates hair
curler bobbins, which, as shown in FIG. 3, are each made up of an
aluminum tube 9 and a resin layer 10 formed on the outer
circumference of the tube 9, said resin layer 10 being formed on
the outer surface with a plurality of projections 11. The aluminum
tubes 9 are adapted to be detachably fitted over the heating rods
7, whereby the hair curler bobbins 8 can be easily attached to and
pulled off of the heating rods 7. When the hair curler bobbins 8
are attached to the heating rods 7 and the heating element 6 is
energized, heat generated by the element 6 is transmitted to the
aluminum tubes 9 through the heating board 5 and heating rods 7,
and stored in the resin layer 10.
On the bottom wall of the container 1 are formed recesses 12 of
arcuate shape arranged in side-by-side relation transversely with
respect to the length of the container. The recesses generally
conform to the outer shapes of the hair curler bobbins 8 so as to
receive the bobbins 8 therein, when the heating panel 5 is rotated
by closing the lid 3, as will presently be described, and the
heating rods 7 with the hair curler bobbins 8 left attached thereto
are moved down. In the container 1 are further formed and arranged
in side-by-side relation in front of said recesses 12 a plurality
of recesses 14 which are adapted to receive therein a plurality of
reserve curler bobbins 13 lying down. The recesses 14 also
generally conform to the outer shapes of the respective hair curler
bobbins 13. In the container 1 are further provided a receptacle 16
for receiving hair pins 15 and a receptacle 18 for receiving a
power cord 17. Between the recesses 12 and the recesses 14 is
interposed a partition wall 19. When the curler bobbins 8 are
received into the recesses 12 with the bobbins 8 left on the
heating rods 7, the hair bobbins cannot fall off heating rods 7
regardless of the position in which the container is placed or
carried. There also is no possibility of the hair curlers received
in the recesses 12 adjacent the receptacle 16 from falling off the
heating rods 7 because of the side wall 16' of the receptacle 16.
Thus, while not in use, not only the hair curler bobbins 8 are
brought down together with the heating rods 7 with the bobbins 8
left attached thereto and are received into the container 1, but
also the reserve curler bobbins 13 are received laid down in front
of the curler bobbins 8, with the result that the container 1 can
be reduced in thickness in a sufficient degree while receiving and
securely holding therein a large number of curler bobbins.
FIGS. 3--6 show the manner in which the heating board 5 is rotated
by opening and closing the lid 3, and accordingly how the heating
rods 7 with the curler bobbins kept attached thereto are brought
down or raised up. The lid 3 is hinged wit a pin 20 to the back
wall of outer frame 2. As shown in FIG. 6, the outer frame 2 is
provided on the rear side with s projections 21 and 21' spaced from
each other, which include pin holes 22 and 22' respectively. The
lid 3 also is provided on the rear side with spaced projections 23
and 23', which include pin holes 24 and 24' respectively. The
respective outsides of the projections 23 and 23' are placed
between the respective insides of the projections 22 and 22', and
the pin 20 is inserted through the holes 22, 24, 24' and 22' and
fixed with respect to the projections 21 and 21', whereby the lid
33 is hingedly connected to the outer frame 2 so as to be pivoted
around the pin 20. The heating board 5 comprises a protective frame
25 of insulating material and a metal body 26. The heating element
6 is located within but electrically insulated from the body 26.
The heating rods 7 are attached to the body 26 and extend through
frame 25. On both sides of the body 26 are disposed pins 27 and 27'
the positions of which are slightly to the right of the medial line
of body 26 in FIG. 3. The protective frame 25 and the body 26 are
connected by a base 28 to which an actuating rod 30 is pivotally
connected by a pin 29. The actuating rod is pivoted at the other
end to a connecting rod 31 by a pin 32. The position of the pin 29
is placed slightly to the left of the medial line of the body 26.
The other end of the connecting rod 31 is pivoted on pin 20 between
the projections 24 and 24' of the lid 3.
The link mechanism is constructed to rotate the heating board 5
through the actuating rod 30 and the connecting rod 31. The lid 3
is provided with a projecting actuating portion 33 above the hinge
knuckles 23, 23' which is located above and to the right of hinge
pin 20 when the lid is closed. The actuating portion 33 is adapted
to engage the connecting rod 31 and causes it to rotate clockwise
around the hinge pin 20 upon opening the lid 3. The lid is further
provided with another projecting actuating portion 34 located to
the left and below the hinge pin when the lid is closed. The
actuating portion 34 is adapted to engage and cause the connecting
rod 31 to rotate counter clockwise around the pin 20 upon closing
the lid 3. This depressing portion 34, however, is not always
necessary. As shown in FIG. 6, the heating board pins 27 and 27'
are pivotally supported by the holes 45 of bearing plates 44 fitted
by screw bolts 43 and 43' to both sides of the container 1. (The
bearing plate on the right side is not shown). The numeral 37 in
FIGS. 3--5 designates a space for receiving the heating board 5 in
the container.
As shown in FIG. 3, opening of the lid 3 causes the actuating
portion 33 to engage and rotate the connecting rod 31 clockwise
around the pin 20. The connecting rod 31 moves the actuating rod 30
to the left rotating the heating board 5 around the pins 27 and 27'
in a clockwise direction. This causes the board 5 to be raised up,
namely to be brought into a horizontal position. Accordingly, the
heating rods 7 are raised up to a generally vertical position.
Closing of lid 3 causes the actuating portion 33 to be disengaged
from the connecting rod 31 thereby to make the heating board 5 fall
by its own weight, rotating counterclockwise around the pins 27 and
27' to bring the heating rods 7 down to a horizontal position.
Provision of the actuating portion 34 makes possible the closing of
the lid 3 by the actuating portion 34 engaging rod 31 to provide
counterclockwise rotation around the pin 20, thereby to assist the
heating board 5 in counterclockwise rotation to positively bring
the heating rods 7 down to the horizontal position.
The operation described above is carried out with the curler
bobbins 8 left attached to the heating rods 7, and when the heating
rods are raised up, the curler bobbins 8 can freely be drawn off of
or fitted over the heating rods 7, as apparent from FIG. 3. When
the heating rods are brought down, each of the curler bobbins 8 is
securely received in its corresponding recess 12. Thus, the
container 1 can be greatly reduced in thickness when the lid 3 is
closed.
In FIGS. 3 through 5, the numeral 35 designates a movable switch
contact 36, a fixed switch contact which opens and closes the
electric circuit (not shown) of the heating element 6 within the
heating board 5. The movable contact 35 is maintained spaced from
the contact 36 by the action of a spring (not shown) when the lid 3
is kept closed. By opening the lid 3 the heating board 5 is turned
clockwise and raised up, and the board 5 presses down on contact
35, as shown in FIG. 3, to bring it into contact with the contact
36. Accordingly, when the lid 3 is opened, the electric circuit for
the heating element 6 is automatically closed. When, as shown in
FIG. 4, the heating board 5 starts rotating counterclockwise around
the pins 27 and 27' by closing the lid 3, depression of the movable
contact member 35 by the heating board 5 is released to disconnect
it from the contact 36 to thereby open the circuit of the heating
element 6. The contact 35 is separated from the contact 36 when the
lid 3 has been closed. Thus, the circuit for the heating element 6
needs no manual closing and opening of a separate switch, but when
it is desired to use the hair curlers, namely the lid 3 is opened,
the electric circuit of the heating element 6 is automatically
closed and connection of the power cord 7 to a suitable power
source supplies the heating element 6 with a current. The heat
generated by the heating element owing to the current thus supplied
is transmitted to the hair curler bobbins through the heating board
5 and heating rods 7, making it possible for the curler bobbins
thus heated to be drawn out of the heating rods to be ready for use
in setting the hair. Furthermore, according to this hair curler,
the circuit for the heating element 6 can automatically be opened
by closing the lid 3 when the curler is not in use, and
consequently there is no possibility of a current flowing through
the heating element 6 while the curler is not used, and hence no
loss of current nor danger of overheating. In this manner, this
hair curler heater is very easy of handling with no possibility of
mistaken handling.
In the embodiment described, it has been illustrated that the lid 3
is connected to the outer frame 2 at one point alone, but it is to
be understood that such connection is possible at two points and
that accordingly provision of the link mechanism including the
actuating rod 30 and the connecting rod 31 also would be made at
two points. Furthermore, the container 1 and the outer frame 2 may
be formed as one integral body and the lid 3 may be connected to
the container 1.
