|20130118487||INFORMATION DISPLAY AND CONTROL DEVICE OF POWERED AIR PURIFYING RESPIRATOR - Disclosed is an information display and control device of a powered air purifying respirator wherein air flow of a blower device is electronically detected using a precision air flow sensor mounted to the blower device without using an air flow display device, and a graphic screen that displays an air flow level meter is displayed on the blower device or an additionally manufactured remote controller so that the air flow of the blower device can be checked during operation. The information display and control device includes a remote controller that is capable of allowing a worker to inspect an air flow state, to detect remaining battery power and expected use time, and to manipulate a blower device and exchanging information even in a state in which the worker wears the air purifying respirator and the blower device.||05-16-2013|
|20130111653||AIR CUSHION FOR ATTACHING HEADBAND OF WELDING MASK - Disclosed is a headband with an air cushion pad, which is mounted on a welding mask, a working helmet, a safety mask or a protective mask. A plurality of air pockets is arranged at regular intervals or asymmetrical intervals within the air cushion pad mounted on the entirety or a part of the headband contacting the worker's head, a plurality of projections is formed on the front surface of the air cushion pad contacting the worker's head, the worker's forehead or the rear portion of the worker's head, and if the worker wears the headband, the amount of air filling air pockets is adjusted according to a shape of the worker's head or a pressing degree of the headband onto the worker's head so that the worker may firmly and comfortably wear the headband under the condition that the headband is completely adhered to the worker's head.||05-09-2013|
|20130111648||CUSHION FOR HEADBAND - Disclosed is a cushion for headbands in which a rear cushion cover is connected to a connection case connected to one selected from a welding mask, a working helmet, a protective mask and a safety helmet and a medical device, and a space recess having the shape of a curved surface is formed on the rear surface of the connection case so that a space having the shape of the cushion cover may be formed between a pad of the cushion cover and the rear surface of the connection case when the cushion cover is connected to the rear surface of the connection case, thereby providing excellent cushion feeling to a wearer when contacting the wearer's head and not causing inconvenience even when the cushion for headbands is worn for a long time.||05-09-2013|
|20120144567||HINGE COUPLING STRUCTURE FOR WELDING MASK, FACE SHIELD AND SAFETY HELMET - Disclosed is a hinge coupling structure usable with a welding mask, a face shield or a safety helmet, which serves to connect either side of a protective mask, configured to cover a welder's face along with a viewing window, to a corresponding end of a head band used to assist a welder in wearing the protective mask. The hinge coupling structure includes a rail longitudinally provided at the head band, a slider coupled to the rail so as to be moved forward or rearward in a longitudinal direction of the rail, and a hinge unit coupled to the protective mask while being coupled to the slider interposed therebetween. The hinge coupling structures enables distance adjustment between the protective mask and the welder's face in a state in which the head band is worn on the head, which provides more convenient wearing of the protective mask.||06-14-2012|
|20120144565||HEAD BAND - Disclosed is a head band to assist a user in conveniently wearing head protective equipment on the head. The head band includes a first band part configured to surround the circumference of the head. The first band part includes first sections located at opposite lateral regions of the head and each provided with a coupling piece for coupling with the welding mask, a second section located on a front region of the head, the second section taking the form of an arc-shaped section having a predetermined radius of curvature when unrolled and being adapted to come into close contact at a predetermined gradient with the forehead, and third sections located at a rear region of the head, the third sections being connectable to each other to enable adjustment in the length of the third sections. The first band part comfortably comes into close contact with the forehead, providing wearer comfort.||06-14-2012|
|20110159918||ANTI-BLINDING DEVICE HAVING WIRELESS COMMUNICATION FUNCTION - Disclosed is an anti-blinding device having a wireless communication function to allow a user to conveniently use a wireless communication cellular phone during operation. The anti-blinding device includes a main control device, a light transmission control device, first and second receiving/transmitting unit to perform signal conversion and transmission between a cellular phone and the main control device, and voice input and output devices. The main control device outputs alarm light and a ringtone using a lamp and the voice output device if it is determined that a digital signal transmitted from the second receiving/transmitting unit is an incoming call signal, and if the digital signal is a voice signal, transmits the digital voice signal to the voice output device. Also, the main control device transmits the digital voice signal from the voice input device to the second receiving/transmitting unit to enable a voice call.||06-30-2011|
|20110156989||METHOD FOR CONTROLLING CARTRIDGE OF WELDING HELMET HAVING DISPLAY FUNCTION OF WELDING OPERATION TIME - Disclosed is a method for controlling a cartridge of a welding helmet having a function to display a welding operation time, which can protect the welder's face from intense light generated during a welding or cutting operation and also, enable automated light transmittance adjustment and operation time setting on a per operation basis, enabling a welding operation to be more efficiently performed. In the method including welding operation, cutting operation, grinding operation and X-mode operation steps, which are automatically performed in sequence according to preset conditions and a light transmittance and operation time of a liquid crystal screen of the cartridge, a control unit calculates an operation time of the liquid crystal screen indicating how long the liquid crystal screen is kept dark, and the calculated operation time is stored in a memory unit so as to be displayed on a display unit in a life mode step.||06-30-2011|
