Description

BACKGROUND OF THE INVENTION

1. Field of the invention
The invention is related to an insulation plate for hair styling work. More particularly, the present invention is related to an insulation plate that reduces labor for hair styling, especially for hair extension work.
2. Description of the Prior Art
FIG. 1 shows an insulation plate by prior art. Hair styling work sometimes involves use of an heater, for example, to melt glue. The example shown illustrates that the insulation plate is used to insulate the heat generated by an electric heater that melts glue in hair extension work. A hair stylist chooses a position around the head of a customer, grabs some strands of customer's hair at the position, inserts the grabbed strands into a slot of the insulation plate, and temporarily fixes the insulation plate on the customer's hair by inserting a hair clip into the customer's hair and over the insulation plate. After finishing hair styling work including using an electric heater which emits high temperature heat, the hair stylist removes the insulation plate by disengaging the hair clip. This sequence is repeated for other positions around the head of the customer until the hair styling work is completed. Use of an insulation plate is essential due to safety concerns involved in using a heater that produces high temperature zone during the hair styling work. Labor handling the insulating plate forms substantial part of hair extension work time and thus the cost of hair extension. An insulation plate that can reduce the labor while preventing danger of the high heat has long been in need.

SUMMARY OF THE INVENTION

An objective of the invention is to provide an insulation plate for hair extension, which reduces steps to finish attaching a strap of decorative hair to a customer's hair.
Another objective of the invention is to provide an insulation plate for extension, which facilitates movement of a hair stylist between a finished hair extension and a next hair extension work.
In order to achieve the above objectives, the present invention provides an insulation plate for hair extension that comprises a base plate, a hair holding plate extending from the base plate and comprising a hair holding slot and a finger holding ring attached to the base plate. The hair holding slot comprises an open end and a dead end that is opposite to the open end, wherein the distance between the dead end and the finger holding ring is predetermined.
The predetermined distance is in the range from 5 mm to 40 mm.
The finger holding ring may be integrated with the base plate and the finger holding ring is partially open opposite to the hair holding plate. In an embodiment, the base plate is flat, the base plate comprises an upper surface and a lower surface, and the finger holding ring is protruded from the upper surface and the hair holding plate is curved away from the lower surface. In another embodiment, the finger holding has shape of a partially open circle, and the center of the circle is near a plane in which the hair holding plate is positioned.
Preferably, the distance between the dead end and the finger holding ring is adjustable. The base plate further comprises a slot that comprises a plurality of notches. The finger holding ring comprises a tooth that moves along the slot and engages with one of the notches, and a ring holding bar that prevents the finger holding ring and the base plate from disassembled.
Alternatively, the base plate further comprises a slot, and the finger holding ring comprises a screw hole, a screw and a nut. The screw passes through the screw hole and the slot, and can move along the slot. The nut tightens the screw when the screw is positioned at a desired position within the slot.
The finger holding ring comprises an aligning groove that is adapted to receive and align strands of hair. The aligning groove is provided on the outer periphery of the finger holding ring opposite to the base plate.
The base plate comprises an upper surface and a lower surface, wherein the finger holding ring is attached to the upper surface, wherein the hair holding plate is curved away from the lower surface.
