Abstract
Description
Description of the invention Title of the invention Mechanical protection prevents cell phone theft by impact and pressure mechanism Technical background of the relevant invention This project is related to the field of mobile phones, which can protect the mobile phone mechanically, and the technical knowledge of this project is in the field of mechanical engineering. Technical problem and stating the objectives of the invention Since mobile phones are becoming larger and larger, it is difficult for people or owners to hold the mobile phone tightly, especially when using and talking. It is stolen. However, using a mechanical protector with a pressure shock mechanism that I designed and manufactured, without the need for electricity or batteries, and shockproof with high strength and small volume and waterproof, without opening the back of the phone and without connecting to the circuit or internal parts of the mobile phone, with completely mechanical intelligence, it protects the mobile phone from being stolen due to its unique design with a pressure shock mechanism that prevents a stranger or (thief) from taking the mobile phone during theft and prevents it from moving away and releasing the mobile phone. A description of the state of the prior art and the history of developments related to the claimed invention. In the past, various methods have been used to increase the security of mobile phones, but they have not been deterrents, for example: - Wireless remote alarm transmission device with registration number 09116149US: It is a portable system that wirelessly connects burglar alarms and wireless security devices and is capable of making telephone calls to a security monitoring station via conventional wired or landline telephone lines via MHz cellular transmission of wireless technologies and activating the vibration sensor in case of movement of the burglar alarm functions. - Device to prevent loss or theft of mobile phones with registration number 0014850: A control device includes a receiver 12, 24 for receiving activation and a controller for controlling the operation of the mobile phone dependent on the activation signal that sends the signal 17, 25. If the phone and the badge are separated and the mobile phone is unable to receive the activation signal, the controller deactivates the mobile phone. - Communication base system for tracking mobile phone theft with registration number 11821108: This system consists of a communication terminal and a standby server to receive the information (GPS) tracking of the stolen mobile phone. For the current locator, a radio frequency module, a camera for taking pictures and a module for storing data memory are designed, to receive the transmitted information, the owner of the mobile phone requires a separate communication device. - United States Patent (2001) Registration Number 6696941: Mobile phone device alarm connected to a system and method for remotely activating audio alarm on mobile phone (PIN) disclosure A remote user calls the mobile phone and enters the personal identification number of the remote calling device. This PIN is processed either within the mobile phone or at a central service. This PIN is compared with a previously stored PIN. A match between the previously stored PIN and the PIN entered by the user generates a signal that activates an audible alarm on the mobile phone to deter theft and aid in the recovery of the stolen mobile phone. - Mobile phone pocket alarm with registration number 91796: We activate this alarm using the activation key and place it in our pocket, then we keep the mobile phone, which is equipped with a small magnet at the bottom, in the same pocket. When the mobile phone is taken out of the pocket due to theft by a thief or loss, the magnetic key is connected and the alarm is activated, causing a warning sound and vibration to be produced by the buzzer and the electric motor, informing the owner of the mobile phone that the phone has been stolen or lost. The main difference between my design and the inventions mentioned is that the design mentioned is completely mechanical. Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention The mechanical guard consists of two parts: the protective floor (1) and the protective door (2). The protective floor has protrusions and slots to place parts inside the protective floor. These grooves and protrusions are: On both sides of the protective floor, there are grooves as the location of the needle-shaped gear (3), short cylindrical protrusions as the location of the gears (4), on the central axis of the protective floor, there are two protrusions as the location of the spring of the gear (5), and on one side and below the protective floor, there is a location of the tongue latch. According to the positions installed in the protective floor, a number of needle-shaped shoulder gears (7) are located on both sides of the floor, the number of which varies depending on the dimensions of the protector, and when the gears (8) are assembled in their positions, each gear engages with a needle-shaped shoulder gear. In the middle of the protective floor, the central shoulder gear (9) (which acts as the mechanism driver) is located, the head part of the shoulder gear has protrusions that are located outside the protector, and in the middle part of the shoulder gear, two grooves are defined in which the springs (10) are assembled in these two grooves. The shoulder gear (9) is engaged with the gears (8) and acts as a driver for the needle-shaped shoulder gear parts (7). At the end of the shoulder gear part, a groove (slot) is defined so that the tab (12) can be placed in this groove if necessary. The end of the tongue is designed to be inclined (wedge) to engage with the inclined surface (wedge) of the tongue latch (14), and the latch piece has protrusions that are located outside the guard and when the latch (14) is moved upward, it guides the tongue into the groove of the shoulder gear (9).This latch acts as a child lock to prevent the mechanism from being activated when not needed. Also, next to the tab, a spring (13) is installed to push the tab out of the groove of the shoulder gear. At the end of the shoulder gear, a hole (11) is designed to match the hole (15) on the protective door and prevent the movement of the shoulder gear (9) with the locking key (16).

No need for electricity or batteries (mechanical mechanism). No need for expertise (the mechanism is not particularly complex). Convenient maintenance. Fast response of the mechanism without delay and high impact resistance. Low cost and economical. Description of at least one implementation method for implementing the invention Deactivation of the mechanism: When we press the upper protrusion of the shoulder gear (9) located outside the guard with our finger and the shoulder gear moves inward, we cause the engaged gears (8) to move and consequently the needle shoulder gear (7) moves inward of the guard and the springs (10) are also compressed. In this position, the groove at the end of the central shoulder gear is opposite the tab (12) and by pulling up the latch (14), the tab is guided into the groove (at this time we can remove our finger from the protrusion of the central shoulder gear) and the spring (13) is compressed, in which case the holes 11 and 15 are opposite each other and we lock the mechanism with the key (16). Mechanism activation: First, pull the latch (14) downwards so that the spring (13) pushes the tab (12) outwards from the groove of the central shoulder gear. In this situation, if the key (16) comes out of the holes (11 and 15), the central shoulder gear (9) moves towards the outside of the guard by the springs (10), and the gears (8) rotate in accordance with the central shoulder gear, and the needle shoulder gears (7) are guided towards the outside of the guard. Based on the mechanism, it is possible to install the protector on the phone with double-sided adhesive. During theft, when the mobile phone is stolen by the thief, the locking key (16) is removed from inside the protector, which is connected to the phone owner's hand with a thread, and the protective mechanism is automatically activated, and the needles come out of the protector from both sides and hit the thief's hand, causing the thief's hand to open. Explicit mention of the industrial application of the invention This product is placed on the back of mobile phones and protects the phone from theft.
