Abstract

The present invention mixes the thermochromic pigments into various door handles, so that the temperature of the part can be changed when the door handle is held by hand, thereby increasing the indoor temperature detection and the value of the product. Plastering paint formed on the surface of the handle (1) 1 to 2% by weight of a known thermosensitive dye (3) having a temperature-sensitive action at 20 to 30 ° C. is added to the layer (2) or the handle body to make a handle having a temperature-sensitive function.

Description

Door handle with temperature sensing function {THERMO SENSITIVE DOORKNOB}

The present invention is to increase the value of the merchandise by mixing the thermochromic pigments in various door handles, so that the temperature of the part is changed by holding the door handle by hand, thereby exerting the temperature-sensitive function.

Thermochromic Colors

The chemical structure of a substance is reversibly changed according to temperature change, and thus the color is changed. Thermochromism is called. Thermochromic substance is called thermochromic dye. Some thermochromic pigments are a single substance, but complex substances are often used to increase their effects.

That is, a coloring agent (developing agent) is mixed with a color for-mer called a pigment | dye or a color body, or it contains a 3rd preparation in many cases.

The dichroic dye was originally developed as a sion pigment instead of a thermometer indicating temperature change. There are inorganic and organic compounds. As inorganic compounds, Ag 2 Hg 14, Ca 2 Hg 14 and the like have been put to practical use, but with the development of liquid crystal technology, many kinds of organic compounds have been used in recent years.

Irreversible is used for thermal recording paper. The recently developed high-temperature composition of CNTs determines the electron acceptor (Electrom, Acceptor) and discoloration temperature that determine the concentration of Electron Donor (Electron Donor). It is composed of alcohols that specifically

1) Electron Donating Compound

3.6- Dimethoxyfluorane: Yellow

3-Cyclohexylamino-6-Chlorofluorane: Orange

3- Dlethlaminobenfraorane: Orange-Red

Rhodamine B lactone: Red

Crystal violet Lactone: Blue

3-Diethlamino-7-Dibenzylaminofluorane: Green

3-Diethlamino-6-Methyl-y- Aminofluorane: Black

2) Electron-soluble compound

Propylgallate

Alcohol carbon number discoloration temperature

N-Octyl Alcohol 8 -40 ℃

N-Dectyl Alcohol 10 -13 ℃

N-Lauryl Alcohol 12 16 ℃

N-Myristil Alcohol 14 35 ℃

N-Cetyl Alcohol 16 45 ℃

N-Stearyl Alcohol 18 53 ℃

When the material coexists, that is, the electron donating material and the electron-accepting amorphous material are generated by the transfer of electrons according to the thermal equilibrium in the atmosphere of the organic material of alcohols, and have a color scheme, and have a color or Leuco structure. It becomes.

The present invention is to produce a new product by applying such a thermal dye to the door handle.

Conventional door handle has a non-temperature change that the coating material coated on the door handle does not change in the external temperature, so there is no change even when holding or applying a hand can not attract people's attention and low commodity value was uncomfortable.

The present invention was developed in order to correct the conventional inconveniences as described above with reference to the accompanying drawings in detail as follows.

1 is a perspective view of the present invention

2 is a cross-sectional view of the component layer of the present invention

3 is another exemplary embodiment of the present invention.

* Explanation of symbols for main parts of the drawings

1: handle 2: plastering layer

3: thermal dye

In forming the plaster coating layer (2) on the surface of the handle (1), the effect of the thermal effect at 20 to 30 DEG C inside the plaster paint agent is as if the paint is added by adding 1 to 2% by weight of the known thermosensitive pigment (3). The handle having a temperature-sensitive function can be made by forming a plaster coating layer 2 on the handle surface or by mixing 1 to 2% by weight of the thermosensitive pigment 3 into a synthetic resin material which becomes a handle molding material when the handle is molded.

In this way, the present invention makes a door handle (1), and when the coating layer is applied to the surface of the coating layer (2) in the colorant having a temperature sensitive function of 20 ~ 30 ℃ mixed in the paint layer to the coating layer When the hand touches, the part warmed by the body temperature discolors, so it can have a temperature-sensitive effect, which can give a favor to the person holding the handle, and can act as a thermometer to detect the high or low indoor temperature. When the door handle is molded and the dye is mixed in the synthetic resin chip that is the molding material, the same effect can be obtained by making the handle by injection molding. There is an advantage to be able to pay.

Claims (1)

A door handle having a temperature-sensing function composed by adding 1 to 2% by weight of a known thermal dye (3) having a temperature-sensitive action at 20 to 30 ° C. to a surface plastering layer (2) of the handle (1) or the handle body.
