Abstract
A hair-curling appliance has a first end and a second end that is rotatably connected to the first end. When the operator moves the hair-curling appliance downward, the first end of the appliance held by an end of an operator is turned to curl the hair of another person, and the second end of the appliance held by the other hand of the operator is not turned during the downward travel of the appliance, thereby keeping a longitudinal axis of the appliance parallel to a horizontal axis and thus preventing deviation of the appliance. A satisfactory hair-curling result is thus obtained.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a hand-held hair-curling appliance of the type that is turned during use so as to curl hair manually. In particular, the present invention relates to a hand-held hair-curling appliance in which deviation thereof is prevented during use to thereby obtain a satisfactory hairstyle.




2. Description of the Related Art




A typical conventional hand-held hair-curling appliance requires the operator to use both hands to respectively hold two ends of the appliance that has clamped the hair of another person and then roll the appliance downward to curl the hair. However, it is difficult for the operator to keep the longitudinal axis of the appliance parallel to a horizontal axis during the rolling, which results in deviation of the appliance. The hair-curling result is thus poor, as the resultant hair has no uniform thickness and is asymmetric and in a mass. In addition to wasting time, re-curling harms the hair again.




SUMMARY OF THE INVENTION




An object of the present invention is to provide a hand-held hair-curling appliance in which deviation during the rolling thereof can be eliminated. The hair-curling appliance has a first end and a second end that is rotatably connected to the first end. When the operator moves the hair-curling appliance downward, the first end of the appliance held by an end of an operator is turned to curl the hair of another person, and the second end of the appliance held by the other hand of the operator is not turned during the downward travel of the appliance, thereby keeping a longitudinal axis of the appliance parallel to a horizontal axis and thus preventing deviation of the appliance. A satisfactory hair-curling result is thus obtained.




Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIGS. 1 and 2

, a hand-held hair-curling appliance in accordance with the present invention generally comprises a heater


10


having a first end


11


and a second end


12


. A heat-transmitting portion


13


is provided on the first end


11


of the heater


10


and made of material that has a high heat conducting efficiency. Plural holes


14


may be formed on the heat-transmitting portion


13


to improve the heat conducting efficiency. Formed on the second end


12


of the heater


10


is a grip portion


15


that is preferably configured ergonomically for easy, comfortable grip by an operator. A heating means (not shown), such as an electric heating means, gas-burning means, etc., is mounted inside the grip portion


15


for heating the heat-transmitting portion


13


. An on/off switch


16


is mounted on the grip portion


15


to control on/off of the heating means. In addition, the heat-transmitting portion


13


includes an annular engaging groove


131


in an end that is distal to the grip portion


15


.




A hair-clamping member


20


is pivotally mounted to the grip


15


at an intermediate portion thereof such that pressing of an end


21


of the hair-clamping member


20


causes the other end


22


of the hair-clamping member


20


to move away from the heat-transmitting portion


13


, best shown in FIG.


3


.




A stabilizing member


30


is engaged with the end of the heat-transmitting portion


13


in a manner allowing relative rotational movement therebetween. In this embodiment, the stabilizing member


30


comprises a first end


31


having an anti-slip section


34


and a second end


32


having an engaging portion


35


. Formed on an outer periphery of the engaging portion


35


are plural protrusions


36


that are engaged in the engaging groove


131


of the heat-transmitting portion


13


, thereby allowing relative rotational movement between the heat-transmitting portion


13


and the stabilizing member


30


, best shown in

FIGS. 4A and 4B

. Transverse slits


37


are defined in the engaging portion


35


to provide the stabilizing member


30


with flexibility.




Referring to

FIG. 5

, the operator may grip the grip portion


15


of the heater


10


with one hand and grip the anti-slip section


34


of the first end


31


of the stabilizing member


30


with the other hand. The hand


6


ripping the grip portion


15


of the heater


10


may be turned relative to the other hand. Referring to

FIGS. 6 and 7

, when in use, the hair is clamped between the heat-transmitting portion


13


and the hair-clamping member


20


. The hair-curling appliance is then moved downward by both hands of the operator. In addition, the heater


10


is turned relative to the stabilizing member


30


during the downward movement of the hair-curling appliance while the stabilizing member


30


is not turned. Thus, a longitudinal axis of the heater


10


is kept parallel to a fixed axis, e.g., a horizontal axis, such that deviation of the heater


10


is prevented. This owes to the relative rotational movement between the heater


10


and the stabilizing member


30


. Thus, the hair of another person is kept in intimate contact with the heat-transmitting portion


13


and thus curled to a required hairstyle after the hair-curling appliance is rolled downward, resulting in a satisfactory hairstyle.





FIG. 8

illustrates a further use of the hair-curling appliance in accordance with the present invention, wherein a hair roller


40


is mounted around the heat-transmitting portion


13


. The hair roller


40


comprises plural rows of teeth


41


and plural openings


42


. The hair roller


40


may be optionally mounted to the heater


10


according to need.





FIG. 9

illustrates a modified embodiment of the hand-held hair-curling appliance in accordance with the present invention, wherein the first end


31


of the stabilizing member


30


is configured to provide an anti-slip section in another form


33


. In addition, the protrusions


36


in the embodiment of the first embodiment is replaced by elongated strips


36


′ without adversely affecting the relative rotational movement between the stabilizing member


30


and the heat-transmitting portion


13


.




Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
