Title:
WATER RESCUE DEVICE FOR ITEMS
Document Type and Number:
WIPO Patent Application WO/2021/024022
Kind Code:
A1
Abstract:
A water rescue device which is attached to any item comprises a diaphragm (3) which due to pressure of water creates a contact in contact blades (6, 7) and activates a microswitch which triggers the valve of the compressed air capsule (10) to open and the air from the compressed air capsule fills the balloon (17) in a regulated manner by funnel-shaped part (13). This enables the item to float on the surface of the water. The microswitch has a delaying function, which prevents the contactor of the system from being activated in short-term blades collision.

Description

Water Rescue Device for Items

Technical Field

[0001] The technical field of this invention relates to accessories of portable electronic devices and gadgets, which prevent them from being submerged and damaged in water.

Background Art

[0002] Application Number: 16011671 , Water Rescue Device for Personal Items

[0003] A salvaging device, particularly for a personal device such as a smartphone dropped into a body of water. A housing has an opening and a gas cartridge. A triggering mechanism is further packed within the housing, which includes a lever arm. A main spring is above the lever arm cocking the lever arm in a downward position.

[0004] A plunger is aligned with the gas cartridge. A water-soluble retainer abuts the lever, wherein upon the retainer dissolving in a water environment, the main spring recoils to thereby unload the plunger into the gas cartridge such that gas can exit the opening. A balloon is connected at the opening inflatable by the gas to thereby provide a buoyancy force to the handheld device upon inflation.

Summary of Invention

[0005] In order to solve the mentioned problems, a device is designed to rescue submerged devices in water and prevents damaging them in different manner than previous inventions. This invention must first be connected to the device. When the device drops in the water, the rescue system is activated as a result of the water hydraulic pressure.

[0006] Once it fell into the water, by an electrical connection, the toggle of the compressed air is triggered, and as a result, the balloon will be inflated and makes the device and its accessories buoyant on surface of the water. Also, as on/off is embedded on the device, the user can enable or disable it.

Technical Problem [0007] While using electronic devices such as a smartphone or tablet, etc. near the pool, the river, the sea, and so on, it's always possible that they drop into the water. Most of these devices are recently waterproof, but if the device is not accessible, it will be impossible to rescue it.

[0008] Also, if the device is submerged underwater for a long period of time, the risk of damage will be increased. Most of such devices are water resistant and if the device goes deep it will be damaged. As a result, a tool that can prevents deep submerging of the device and makes buoyant them on the surface can solve the problem quickly.

Description of Embodiments

[0014] The main body (15) of this device which is made of composite materials is closed by a lattice lid (1) and the rest of the parts are embedded inside the body. If the device falls in the water, the water passes through the lattice lid but it prevents damage to the interior parts. The first (2) and the second (4) gasket gaskets are placed on two sides so that diaphragm can function properly.

[0015] As the device submerges deeply in water, the much more hydraulic pressure of water exerts on the diaphragm. In this case, the diaphragm which has high elasticity is inflated into the device. The system function precision is directly proportional with diaphragm area. The more diaphragm area, the higher system function precision is. Since the hydraulic pressure at the water surface is low, the diaphragm can also be activated under low pressure.

[0016] The inflated diaphragm collides with another plastic gasket (5) that only transfers the diaphragm pressure down from one side. On the microswitch (18), two contactors blades (6) and (7) are connected to activate the microswitch. One of these blades (6) which is in contact with a one-way plastic gasket (5) is connected from one side to the microswitch and the other side is free.

[0017] As a result of the movement of the one-way plastic gasket, the moving contactor blade (6) moves inwards device and collides with the fixed contactor blade (7) and the circuit current is established. The fixed contactor blade (7) is connected to the microswitch from one side and the main body from the other side. The microswitch is of the normally open type that has an on/ off switch (8). The microswitch has a delaying function, which prevents the contactor of the system from being activated in short-term blades collision. Such collision may be caused by device rapid shaking. The microswitch receives the energy needed to trigger the toggle from the capacitor. The solenoid also can be effective in this process. These pieces are embedded inside the microswitch. Once the two contactor blades are connected and activated, the microswitch circuit triggers the toggle (19).

[0018] The capsule activation system includes the following parts:

[0019] On the end of the compressed air capsule (10) a fixed lid is embedded (9). On the other end, there is a lattice cylindrical lid part (11) which pushes the valve to release air.

[0020] When the toggle is triggered, the metal spring (12) pushes lattice cylindrical lid part toward valves, in turn air pressure pushes the cylinder back as soon as it leaves the capsule. In this case, capsule stops releasing air. When the air pressure is balanced, the spring can press the lattice cylindrical lid part toward valve (damping), and this is repeated until the air is depleted in the capsule. This will result in the slow and controlled release of air from the capsule, which eliminates any possibility of destruction of the device or tearing of the balloon. It is possible to set the air release from the compressed air capsule in one to three seconds, which is a function of available holes size on the lattice cylindrical lid part.

[0021 ] In order to direct the air to the end of the balloon (17) and to fix it, a funnel- shaped part (13) is embedded. A cavity device is embedded on the body to remove the balloon. This hole is maintained by a closed lid (16) and the balloon pressure removes it from the body and it is removed from the related hole (20). Once the balloon is inflated, the system and accessories are buoyant and can be easily identified and picked up. If it is not possible to stick the system to the device, a cavity is embedded on the body (14), so that by a strap system can be attached to the device.

Advantageous Effects of Invention

[0022] - Automatic salvage of portable device after falling in the water;

[0023] - The possibility of adjusting the device's activating (during production)

[0024] - Use the diaphragm area to detect the hydraulic pressure of the water, which reduces the thickness of the system (about 8 mm);

[0025] - Using large diaphragm area to detect the hydraulic pressure of the water, which increases the accuracy of the system activation;

[0026] - No sensitivity to air humidity;

[0027] - Gradually direction of air flow into the balloon;

A method for applying the invention

[0030] In order to implement and use this device, the user should attach it to the mobile, camera, or any other device, and select the activation button. If the device falls in the water, the system is automatically activated and keeps the device floating on the water.
