Description

A silicone remover

More particularly, the present invention relates to a silicon eliminator, and more particularly, to a silicon eliminator which improves the removal efficiency without removing a large amount of force when silicon is applied, The present invention relates to a silicon eliminator capable of improving the workability of silicon removal by hand by reducing the inconvenience of using two tools in the silicon removal work by providing the removal blade in a folding manner in the handle.

Generally, a window frame (chassis) is installed on a veranda of a common house (an apartment, a villa, a residential complex, etc.), that is, a balcony, and the window frame is generally made of aluminum or synthetic resin (plastic).

Waterproofing effect can be obtained by treating sealant such as silicone for various seams of seams, kitchens, bathtubs and the like for the purpose of preventing water leakage. Silicone thus formed is oxidized or cured in the sun over time, causing leakage of water.

Therefore, it is frequently necessary to repair the silicon that has been constructed. In order to re-work the silicon, the silicon that has been pre-applied is removed one by one, and then silicone is newly attached to the silicon gun and applied to the seam part.

In order to remove the silicon, there is a disadvantage that it takes a long time to remove the silicon by using a scraper or a cutter blade tool which is widely used as a manual tool. Therefore, a silicon remover which can remove silicon easily is used.

[0004] In view of the prior art related to the above silicon remover, Japanese Patent Application Laid-Open No. 10-2015-0091589 (entitled Corner Silicon Eliminator, published on Aug. 12, 2015, hereinafter referred to as "Seonen Document") has been disclosed .

The corner silicon eliminator of the prior art includes a body having a fastening portion for fastening a silicon removing knife to a front end thereof, a body having a rear portion formed integrally with a residue removing knife having a blade at a lower end side thereof, A silicon removing knife made of a metal material and formed of a V-shaped removing knife having a blade formed at the tip end thereof and a fixing plate formed in a horizontal state.

In the corner silicone remover of the above-mentioned source document, silicon is removed easily at the corner side by using a silicon removing knife having a silicon removing knife and a residue removing knife provided at the body and formed at an angle of 90 degrees, and a rear- To remove the silicon residue used.

However, the silicon remover is formed by simply adding a residue removing knife to the body formed of a plastic material, and the blade part easily becomes dull due to a single use.

In particular, since the blade for removing residue is exposed to the outside, when the rough portion is used, the blade portion is damaged. When the blade is mixed with other working tools, the blade portion is damaged by the interference of the blade portion. Unlike the blade, it is difficult to reuse.

In addition, since it is exposed to the outside, it is pointed out that there is a disadvantage that it interferes with the glove for work or the arm of the work clothes when using the silicon removing knife.

On the other hand, the silicon removing knife is bent at 90 degrees in a pointed shape with a sharp tip, and the blade portion is formed only on the upper surface side, and a large amount of force is initially applied to push the silicon portion in the corner. The reason for this is that the leading end of the removing knife can penetrate deep into the corner of the silicon, but the force of pushing the silicon by only the angle of the blade formed on the top surface is a little strong and the efficiency of the work is low.

In order to improve the workability due to the removal of silicon, it is necessary to remove it quickly. However, since it takes a lot of power with only the pointed end and one side of the blade, it increases the fatigue of the worker and works with unreasonable force. Follow.

It is an object of the present invention to improve the silicon eliminator and to efficiently remove silicon without removing a large amount of silicon when removing the silicon, It is possible to reduce the inconvenience of using the two tools in the silicon removing operation by providing the corner eliminating blade for removing the corner portion which is easy to remove so as to improve the manual silicon removing workability The purpose is to provide.
