Abstract:
The present invention relates to a mathematics and geometry device for visually impaired (1) comprising retractable push-buttons (2) at least one button body (4) which enable the push-button to be placed on the socket (3) and making a linear movement towards the inside-outside of the device when the push-buttons are pressed; and at least one lock system which is located on the button body and which enables the button body to be locked in upper and lower positions; when the button body is locked in the upper position, the push-button becomes an open button; when the button body is locked in the lower position, the push-button becomes a closed button.
