Description

Description A CASING
[ 1 ] Field of the Invention
[2] The present invention relates to a casing which protects portable devices against shocks and external impacts and which enables them to operate more efficiently.
[3] Prior Art
[4] Portable electronic devices (e.g. remote control, mobile phone, MP3 player) are exposed to shocks for reasons like dropping or collision during use and they get damaged. Additionally, the said devices can not carry out their functions as a result of weakening or running down of their batteries during use. Charging the discharged batteries, or replacing the batteries in devices where rechargeable batteries are not used, lead to difficulty in use.
[5] The Canadian patent document No. CA2398318, an application within the state of the art, discloses a casing comprising an air cushion developed to protect electronic devices. The casing, comprising a pneumatic chamber which is filled with air and which surrounds a device such as a remote control, etc., has an air valve at the air inlet point.
[6] The Chinese patent document No. CN2859896Y, an application within the state of the art, discloses a battery-free remote control, which is charged by nipping in the hand. Upon turning the wheels in the remote control by means of the lever actuated by the user, kinetic energy is converted into magnetic energy and then to electrical energy.
[7] Various solutions are available in the state of the art for charging the batteries used in devices during use. In these solutions, mechanical energy of lever or cranks actuated by the user is used as electrical energy. However, the user is required to directly intervene or exert extra power to generate mechanical energy. Furthermore, the said charging apparatuses do not have the feature of operating as a result of the use of the device that they are provided in. Thus, there is not provided any application in the state of the art which simultaneously realizes charging of the device, which is placed therein, during use of the device without any additional effort, and protects it against external impacts.
[8] Summary of the Invention
[9] The objective of the present invention is to realize a casing, which protects portable electronic devices against external impacts and provides the energy required by the said devices.
[10] The casing realized to fulfill the objective of the present invention and defined in
Claim 1 and in its dependent claims, comprises a liquid mass which freely moves within the closed channel provided in the casing. Mechanical energy is obtained by using an element which is located in the channel and moves upon passage of the liquid, and this energy is converted to electrical energy whereby the device placed within the casing is charged. It is possible to design the channel in various geometrical forms (e.g. circular, U-shaped with two ends closed, linear). In one embodiment of the invention, the element which moves with the passage of the liquid within the channel is a fan. The casing provides ease of use since it provides protection for the device disposed therein against external impacts and shocks and at the same time carries out the functions of providing electrical energy needed by the device. Charging the device during use, extends lives of the batteries that operate the device. Thus, the batteries do not have to be recharged or replaced. Additionally, the inventive casing enables devices to be operated without using batteries owing to its energy storage unit.
[11] Detailed Description of the Invention
[12] The casing realized to fulfill the objective of the present invention is illustrated in the accompanying figures in which,
[13] Figure 1 is the view of an embodiment of the inventive casing together with the device placed therein.
[14] Figure 2 is the front view of an embodiment of the inventive casing.
[15] Figure 3 is the front view of another embodiment of the inventive casing.
[16] Figure 4 is the front view of a further embodiment of the inventive casing.
[17] Figure 5 is the schematic view of the charging connections of the inventive casing.
[18] The components shown in the figures are numbered as follows:
[19] 1. Casing
[20] 2. Channel
[21] 3. Liquid
[22] 4. Propeller
[23] 5. Converter
[24] 6. Storage
[25] The casing (1) used for protecting electronic devices (A) such as remote controls and mobile phones against external shocks is filled with a fluid material (e.g. water, fluid gel, air). The process of filling with fluid is preferably realized in the production phase and the casing (1) is presented to the user as filled with fluid. The casing (1) which has a voluminous form when filled with fluid, surrounds the bottom and side surfaces of the electronic device (A) intended to be protected. The upper surface of the said device (A) including the keys and displays is not covered by the casing (1), so use of the device is not hindered. The casing (1) comprises at least one channel (2) which is located within a volume filled with a fluid and has a certain amount of liquid (3) that can freely move therein and at least one propeller (4) which rotates with the movement of the liquid (3) therein; a converter (5) which converts the mechanical energy arising as a result of the rotation to electrical energy; and a storage (6) wherein the electrical energy obtained by means of the converter (5) is stored (Figure 1).
[26] The casing (1) is made of a resilient and durable material (e.g. plastic) which does not leak out the fluid therein.
[27] The channel (2) provided within the casing (1) is circular (Figure 2) or U-shaped with two ends closed (Figure 3) or linear (Figure 4). The amount of the liquid (3) is such that it will not fill the entire volume of the channel (2), for example, it will fill about half of the channel volume, and it can freely move within the channel (2). The propeller (4) is disposed such that its rotation axis is perpendicular to the profile of the channel (2) and rotates upon passage of liquid (3) therethrough.
[28] Upon movement of the device (A) during use, the liquid (3) travels freely in the channel (2) and enables the propeller (4) to rotate when passing over it. Mechanical energy is obtained by means of rotation of the propeller (3). The converter (5) connected to the propeller (4), converts the mechanical energy that results from the rotation of the propeller (4) to electrical energy and transfers it to the storage (6) via an electrical connection. The storage (6) stores the electrical energy transmitted by the converter (5) and transfers it to the device (A) (Figure 5).
[29] In one embodiment of the invention, the storage (6) is a rechargeable battery or a capacitor independent of the battery of the device (A). In the case that the storage (6) is a unit separate from the battery of the device (A), the electrical energy accumulating thereon enables charging of the battery of the device (A) and thus ensures extension of the battery life of the device (A).
[30] In another embodiment of the invention, the rechargeable battery of the device (A) is used as the storage (6). In this embodiment, the electrical energy provided by the converter (5) is directly transferred to the storage (6) comprised of the rechargeable battery of the device (A) and battery life of the device (A) is extended owing to the fact that the battery of the device (A) is charged.
[31] In a further embodiment of the invention, there is a plurality of propellers (4) disposed at various points in the channel (2) and all which are connected to a single converter (5). Thus, the possibility of transferring the movement of the liquid (3) in the channel (2) to the propeller (4) is increased and the assembly that generates energy for the device (A) operates more efficiently.
[32] In yet another embodiment of the invention, the casing (1) comprises a sealing cap which is disposed on any point of the outer surface; which does not leak out the fluid in the casing (1) when it is closed; and which is used in filling and discharging the casing (1). This way, filling the casing (2) with fluid can be performed by the user as well as it can be performed during the production phase.
[33] The casing (1) filled with fluid generates mechanical energy during use, by means of the liquid (3) freely moving in the channel (2) rotating the propeller (5) when it passes therethrough. This energy is converted to electrical energy by the help of the converter (4) and it is transferred to and accumulated in the storage (6). Thus the energy to be used in operating the device (A) placed within the casing (1) is obtained. The device (A) placed within the casing (1) is protected against external shocks owing to the resilient and voluminous form acquired by the casing (1) that is filled with fluid, and additionally the energy needed for its operation is obtained by means of the liquid (3) that moves within the channel (2) rotating the propeller (4) upon movement of the device (A) during its use, without any additional effort by the user.
[34] Within the scope of this basic concept, it is possible to develop various embodiments of the casing (1). The invention is essentially according to the claims and it can not be limited to the examples explained herein.
