| 20130219789 | TWO-STAGE LINKED SLIDING DOOR OF MACHINE TOOL - A two-stage linked sliding door of a machine tool is provided with a first door half and a second door half movable through different strokes. Pulleys are disposed individually at two opposite end portions of the second door half, and a wire is stretched between the pulleys. The opposite end portions of the wire are secured to the door frame or the first door half by two wire tensioning springs, individually, such that the opposite end portions face each other. These two springs are juxtaposed and offset with each other so that their respective central axes do not line on the same axis. | 08-29-2013 |
| 20140259933 | DOOR COORDINATOR ACCESSORY MOUNTING BRACKET - An accessory mounting bracket for securing door accessories to a door coordinator. The accessory mounting bracket has stepped portions that define a channel that is sized to receive a door coordinator. A recess is disposed below the channel and provides an offset for fasteners that mount the door coordinator to a door frame and may protrude from the door coordinator. A set of bores are used to attach the accessory mounting bracket to the door coordinator and a soffit of the door, while a second bores, which are threaded, allows for attachment of a door accessory to the accessory mounting bracket. The second bores are formed in the accessory mounting bracket so as to be spaced apart from the door coordinator. | 09-18-2014 |
