| 20130084131 | TAPERED THREAD CONFIGURATION WITH IMPROVED DURABILITY - Underground drilling operation often requires connecting a drill tool (e.g., drill bit, backreamer, etc.) to a drill string. It is desirable to connect the drill tools to a drill string in a manner that facilitates quick and easy assembly and disassembly. Low torque coupling, commonly referred to as “torque-less” connection, can provide such functionality. The useful life and strength of such connections can be improved upon. The present disclosure provides a low torque coupling with improved strength and durability. | 04-04-2013 |

| 20110243655 | DISTANCE DEVICE AND FASTENING SYSTEM HAVING DISTANCE DEVICE - A distance device bridges a free space between a carrier part and a roof body for fastening a roof luggage rack, such as a roof rail, a roof strip or the like, on a vehicle roof by a threaded screw, with a support part and a counter support part. The support part and counter support part are held together by a threaded connection and can be adjusted relative to each other in order to set a bridging length. The support part or counter support part is carried along by a rotationally engaging connection with the threaded screw when it is screwed into a counter thread of the roof luggage rack or carrier part as far as a contact position with the carrier part or the roof body. The rotationally engaging connection has a plastic carrier into which the thread of the threaded screw is/has been screwed for carrying along with frictional resistance. | 10-06-2011 |

The device includes a first component member including at least two protruded portions each having a predetermined lead angle, and a second component member which keeps predetermined positional relationship with the first component member and has at least two protruded portions which are engaged with the protruded portions of the first component member, among at least two of which protruded portions, at least one of the protruded portion has a different lead angle from the lead angle of the protruded portions of the first component member, and the first and second component members can be moved closer opposite each other, the protruded portions are engaged with each other after moving opposite each other by a certain distance, and the first and second component members are integrally fixed by frictional engagement of the protruded portions differing in the lead angle. | 12-30-2010 |
| 20100129147 | ROOF TO POST ADJUSTABLE HOLD DOWN DEVICE - A connector to connect a pair of components of a building and transfer a load from one to the other. The connector comprising a pair of members, each to be connected to a respective one of the components, and an adjustable abutment acting between the members to inhibit relative movement between the members in one direction. The ratchet mechanism acting between the members to permit movement in the one direction and to inhibit relative movement in an opposite direction, whereby adjustment of the abutment to cause relative movements in the one direction is accommodated by the ratchet mechanism. | 05-27-2010 |
| 20100003075 | SHAFT-HUB CONNECTION WITH TOOTHING - A method for producing a shaft-hub connection, in particular between a helically toothed pinion ( | 01-07-2010 |
| 20120082509 | INTERFACE DEVICES AND METHODS OF USING THE SAME - A housing is disclosed having ends capable of receiving tool head interfaces and tool handle interfaces. One of the ends can be configured as a specialized interface end and the other end can be configured as a standardized interface end. One example of a standardized interface end is a threaded interface. An example of the specialized interface end is a selectively engaged end having a plurality of detents for variable positioning of the tool head end relative to the tool handle end. | 04-05-2012 |
| 20100183366 | BROOM ASSEMBLY - A broom assembly includes a head structure and a rod structure. The head structure includes a base having a coupling face formed with a reception chamber and an opening for access into the reception chamber, and a plurality of resilient ribs provided at the periphery confining the opening and extending inwardly and radially toward a center axis of the opening. The rod structure includes a coupling member provided partially, rotatably and detachably within the reception chamber in the coupling face of the base. When the coupling member is detachably received within the reception chamber, the coupling member biases against and engages the resilient ribs so as to be prevented untimely disengaging from the base. | 07-22-2010 |
