20100193560 | Trigger Valve for Nail Gun - A trigger valve includes a valve base, a valve rod, a sliding portion and a shuttle valve. The valve base is disposed at a gun body of the nail gun between a compressed chamber and a main air valve of the nail gun. The valve rod is capable of being driven by a trigger of the nail gun to move so as to open or close high pressure air from the compressed chamber into the valve base. The sliding portion is capable of being driven by high pressure air to move to cause a safety slide rod of the nail gun producing a displacement along a hitting-nail direction. The shuttle valve is capable of being driven to move under control of the displacement of the sliding portion so as to open or close high pressure air from the valve base into the main air valve. | 08-05-2010 |
20110180580 | PORTABLE FASTENER DRIVING DEVICE - The present invention includes various embodiments directed to apparatus and methods surrounding a fastener device. In particular embodiments, the fastener device is a quick charging and discharging device that includes a solenoid, a fastener striker, a flash capacitor, and a control circuit. Other novel features of the fastener device exist. In particular embodiments, the present invention also includes apparatus and methods related to deforming staples for securing conduit and the like, and staple insulation and insulated staples that may be discharged by the fastener device. The insulation may be provided in an ordinary staple strip for use in the fastener device. Each insulation form may include deformation voids to assist the adaptation of the insulation about a target object that is being secured by the insulated staple. | 07-28-2011 |
20120241489 | ELECTRONIC DEVICE WITH STAPLING MECHANISM - An electronic device includes a tray, a light source, a sensor, a control module, a puncher assembly and a stapler assembly. The light source is located on the tray and emits light. The sensor is located on the tray and detects a thickness of sheets of paper output from a printer. The control module defines a predetermined height and compares the predetermined height with the thickness of the sheets of paper. The stapler assembly is located on the tray and capable of stapling the sheets of paper. The puncher assembly is located on the tray and can perforate the sheets of papers. If the predetermined height is greater than the difference, the control module drives the stapler assembly to staple the sheets of papers. If the predetermined height is less than or equal to the difference, the control module drives the puncher assembly to perforate the sheets of papers. | 09-27-2012 |

20090294503 | Cam-actuated pneumatic switch mechanism system for controlling the timed spacing of fasteners drive from hand-held fastener-driving tools - A fastener-driving tool has a cam-actuated pneumatic switch mechanism system operatively incorporated thereon which is adapted to control the timed driving or discharge of fasteners out from a hand-held fastener-driving tool and into a substrate at predeterminedly spaced positions with respect to each other. The arrangement is particularly adapted for use in connection with the driving of fasteners into corner regions of structural workpieces, although the same may also be used to drive fasteners into flat planar surfaces. | 12-03-2009 |
20100301090 | ELECTRIC STAPLER - An electric stapler includes: a driver for driving leg portions of a staple having a U-shaped section to penetrate the leg portions through a paper bundle; a table including a clincher for bending and forming the penetrated leg portions inwardly, the table for holding the paper bundle between the driver and the table; a motor for moving the table and the driver; a photo sensor for detecting an existence of the paper bundle inserted into a gap between the table and the driver; and a control portion for driving the motor. The photo sensor is disposed on the table in such a manner that a detection point of the photo sensor for detecting the paper bundle exists upwardly of a disposing position of the clincher by inclining an optical axis direction of a radiation light to be emitted from the photo sensor in a direction of the clincher. | 12-02-2010 |
20160031255 | BOOKLET MAKING MACHINE WITH THICKNESS SENSOR - A booklet making machine is provided, comprising a stapling arrangement adapted for stapling a stack of sheets following a paper path. A contacting device is adapted to contact the stack of sheets and a drive means is adapted to impart a reciprocating movement of the contacting device. By means of a sensor adapted to determine the distance of the movement of the contacting device, the thickness of the stack of sheets can be determined. | 02-04-2016 |
