The present invention relates to impact protection devices, in particular, a device for protecting a cellular telephone or other such portable appliances.
BACKGROUND OF THE INVENTIONPortable appliances or devices such as cellular telephones and the like are extremely popular devices and users commonly carry cellphones in their hand when walking around. Other examples of portable appliances/devices include personal data assistants, electronic media players, notebook-type computers, video and still-photo cameras, pagers, portable video game players and so forth. As such, cellphones, etc, are often accidentally dropped causing expensive damage and inconvenience.
To ameliorate this issue, there have been disclosed relatively uncomplicated protection devices such as mobile telephone cases; as well as slightly more sophisticated systems as disclosed in KR 100845221 “Liquid crystal display protect apparatus of cellular phone” (Kim) where a user presses a button to activate a screen protection mechanism; and even more sophisticated systems as disclosed in U.S. Pat. No. 7,059,182 “Active impact protection system” (Ragner); and U.S. 2011/194,230 “Protecting devices from impact damage” (Hart et al), which provide mechanisms for automatically determining a need for protection.
SUMMARY OF THE INVENTIONThe present invention relates to an impact protection device, in particular, a device for protecting a cellular telephone or other such portable equipment.
The present device is designed to at least protect the particularly fragile display area (screen) of the portable equipment by activating a protective cover when a need is perceived. The present device or protector operates automatically in that the protector can both deploy the protective cover, when the protector deems it appropriate, and can retract the protective cover when the need for protection is no longer perceived, e.g. when the protected equipment is held in one's hand or resting on a surface such as a table.
In accordance with embodiments of one aspect of the present invention there is provided a cellphone protector for protecting a portable appliance having a screen, the protector comprising: a cellphone protection mechanism; a protection-requirement detection mechanism adapted to actuate the cellphone protection mechanism; and a housing for housing the cellphone protection mechanism and the protection-requirement detection mechanism. The cellphone protection mechanism comprises at least one screen protection shutter adapted to cover and uncover the screen and provide protection thereto; and a shutter opening and closure mechanism operably connected to the at least one shutter and adapted to open and close the at least one shutter for respectively uncovering and covering the screen. The protection-requirement detection mechanism is adapted to detect whether or not there is an object adjacent the protection-requirement detection mechanism, and adapted to actuate the shutter opening and closure mechanism of the cellphone protection mechanism.
In some embodiments the shutter opening and closure mechanism comprises: a winding wheel; a shutter winding shaft associated with the winding wheel; a solenoid operably connected to the winding wheel; a shutter closure shaft; a shutter retraction spring associated with the shutter closure shaft; and a micro-processor adapted to receive a signal from the detection protection-requirement detection mechanism and operably connected to the solenoid.
In some embodiments the shutter opening and closure mechanism comprises: a shutter opening motor; a shutter winding shaft associated with the shutter opening motor; a shutter closure shaft; a spring associated with the shutter closure shaft; a micro-processor adapted to receive a signal from the detection protection-requirement detection mechanism and operably connected to the shutter opening motor; and a shutter closure spring associated with shutter closure shaft.
In some embodiments the shutter opening and closure mechanism comprises: a shutter opening motor; a shutter closure motor; shutter winding shaft associated with the shutter opening motor; a shutter closure shaft associated with the shutter closure motor; a micro-processor adapted to receive a signal from the detection protection-requirement detection mechanism and operably connected to the shutter opening motor and the shutter closure motor.
In some embodiments the protector further comprises at least one track for guiding the shutter.
In some embodiments the protection-requirement detection mechanism comprises a circuit including adjacent serpentine wires. In some embodiments the protection-requirement detection mechanism comprises a distance sensor for detecting the object adjacent the protection-requirement detection mechanism. In some embodiments the protection-requirement detection mechanism comprises both the circuit and the distance sensor. In some embodiments the protection-requirement detection mechanism comprises at least one contact and the housing is adapted to be moveable to press on the at least one contact as a result of the protector being held by a user, to close a circuit.
In some embodiments the shutter comprises upper and lower shutter pulling strips defining upper and lower borders of an open area, which substantially corresponds to the screen area.

DETAILED DESCRIPTION OF THE INVENTIONIllustrative embodiments of the invention are described below. In the interest of clarity, not all features/components of an actual implementation are necessarily described.
Protection mechanism 10 includes a screen impact protection cover or shutter—typically a pair of such shutters 14a and 14b in this embodiment, as shown (one shutter shown in
Motors 16a and 16b are operably connected to respective shutters 14a and 14b via motor shafts 18a and 18b, respectively, upon which the shutters are wound, when the shutters are open; and from which the shutters are unwound, when the shutters are closed. In some embodiments, as shown, shafts 18a and 18b are connected to respective motor axles or shutter winding axles 20, for example at point 22 (
In some embodiments, motors 16a and 16b and motor shafts 18a and 18b are oriented parallel to shutter ribs 26. In other embodiments, motors 16a and 16b are not parallel to shutter ribs 26, for example perpendicular as shown, and protection mechanism 10 includes a rotation transmission mechanism 28 respectively associated with motors 16a and 16b. In some embodiments, protection mechanism 10 further includes one or more guide tracks, such as a pair of guide tracks 30, in which the ends of shutters 14a and 14b pass in order to help properly guide and position the shutters during deployment (covering screen S) and retraction (exposing screen S). In some embodiments, each motor 16a, 16b has an associated limit switch 32; otherwise the motor may merely have a timer (not shown).
With reference to

Operation: When the cellphone, substantially housed in housing 100 of the instant cellphone protector, is held, the user's hand, being conductive, closes circuit 44 (by bridging between wires 40 and 42) of protection-requirement detection mechanism 12. As a result, micro-processor 48 signals motors 16a and 16b to move shutters 14a and 14b to an open position (or maintain the shutter in an open position, e.g. not change the position if already open) so that cellphone screen S can be viewed and the cellphone can be conveniently used. In the embodiment just described, shutters 14a and 14b are wound/unwound in order to move them, in accordance with the above-described cellphone protection mechanism 10; however, in some embodiments, the shutters are pushed and pulled or otherwise moved, for example by one or more biasing elements, as will be discussed below.
If the user drops the cellphone, the user's hand will no longer close the circuit, and micro-processor 48 will cause motors 16a and 16b to close shutters 14a and 14b, thereby helping protect cellphone screen S from impact damage.
Reverting to
If the cellphone is dropped or slips from a table or other such surface, sensor 50 detects the increased distance from the object upon which the cellphone rested and sends a signal to micro-processor 48 to operate motors 16a and 16b to close shutters 14a and 14b, thereby protecting screen S.
Cellphone protector can include both circuit 44 and sensor 50; or just the sensor, or just the circuit. For rigorous operation and increased dependability, the cellphone protector typically includes both circuit 44 and sensor 50.
To accomplish the pulling of single shutter 14, the shutter has a pair of shutter pulling strips 52a and 52b, exemplified in
To open shutter 14 (not seen in
