Abstract

PURPOSE: A multifunctional pen for noise cancellation is provided to effectively prevent the occurrence of minute noise by blocking the noise problem generated in the change of colors in the multifunctional pen. CONSTITUTION: A multifunctional pen for preventing noise is able to change colors and functions of a pen by using a pushing method. The multifunctional pen for preventing the noise is located at an upper end unit to enable a user to feel convenience in use. The complex functional pen for the noise reduces the noise by eliminating elastic members when a part of a ball pen is connected to a flexible part. The color of the ball pen is changed by using a nock type upper end.

Composite pen for noise prevention {Mechanical pencil and pens work by pushing without noise}

Invention of life

Multifunctional pen for noise prevention using conventional sharp and ballpoint pen

The above invention relates to a compound pen using a push method for making no noise, which can solve the problem of being disturbed by sound. In order to make no sound, the spring was removed from the knock and spring method of the existing sharp or multi-pen method, and it was fixed by using a little friction and locking structure.

Since noise is a phenomenon that occurs when using a spring, remove the spring and put the ball pen and the soft parts when the body is caught to reduce the sound. The pen's tail is at the bottom, so it can be used conveniently. When the ball pen is lowered, the pen can slide to prevent sudden changes of color or rising of the pen. Existing sharps or noise-canceling multi-pens used spring-loaded materials to reduce noise, while reducing noise, most of which were inconvenient to use the switch function located in a location that was not easy to use.

If you use a compound pen, there is a way to block the noise problem when exchanging the color or function of the pen, but it is effective in suppressing the fine noise by changing the format so that it does not sound completely. In addition, when using the stomach in consideration of the convenience to close the hand and to increase the grip to the front to enable the function to be pushed in the movement through the fixed structure inside.
