20160032951 | A LOCK FOR A TELESCOPIC SUPPORT ELEMENT - The disclosure is directed at a lock for a telescopic support element including a housing including a central passageway for receiving the telescopic support element; a first cam mounted inside the housing adjacent the passageway; and a second cam mounted inside the housing adjacent the passageway opposite the first cam; wherein movement of the telescopic support element from a contracted position to an extended position within the central passageway causes the first cam and the second cam to rotate from an unlocked position to a locked position thereby locking the telescopic support element in place. | 02-04-2016 |
20160077412 | TELESCOPING DEVICE - A telescoping device capable of preventing a lower tubular body from jouncing during fixation by a fixing unit includes a leg body being a telescoping device includes an upper tubular body, a lower tubular body, and a fixing unit that releasably fixes the lower tubular body with respect to the upper tubular body. The fixing unit includes an operation body and a fixation body. The fixation body consists of an outer member, an upper inner member, and a lower inner member. On the outer member, inner peripheral upward inclined surfaces and inner peripheral downward inclined surfaces are formed. On the upper inner member, outer peripheral downward inclined surfaces are formed, and on the lower inner member, outer peripheral upward inclined surfaces are formed. | 03-17-2016 |
20160138635 | Telescopic Rod - A telescopic rod includes a large-diameter rod segment, a small-diameter rod segment, and a clamping unit. The large-diameter rod segment is telescopically joinable to the small-diameter rod segment, and includes a uniform-dimension main region, a marginal region, and a dimension reducible region which has left and right grip areas defined by an elongated gap and proximate and distal transverse slots communicated with the elongated gap. The clamping unit is displaceable between an untightened state and a tightened state, where the dimension reducible region is squeezed by the clamping unit such that the left and right grip areas tightly and evenly grip the small-diameter rod segment. | 05-19-2016 |

20120288326 | ROTATING TYPE STICK - The present disclosure relates to a rotating type stick capable of firmly maintaining a locking state of a locking unit even when a rotational force is applied to tube members constituting a stick. Provided is a stick including: a first tube member and a second tube member connected to each other in the length direction; and a connection member connected to one end portion of the second tube member, wherein the first tube member is selectively locked to or unlocked from the connection member, the second tube member is rotatably connected to the connection member, and the second tube member is rotatable relative to the first tube member while the first tube member and the connection member are maintained in a locking state. | 11-15-2012 |
20130223926 | CONNECTION SYSTEM FOR CRANE COMPONENTS - A mobile lift crane includes a carbody having movable ground engaging members; a rotating bed rotatably connected to the carbody; a boom pivotally mounted on the rotating bed; a first hoist drum mounted in a first frame connected to the rotating bed; a second hoist drum mounted in a second frame connected to the rotating bed. Connectors used to connect the load hoist drum frames to the rotating bed include engagement members and alignment surfaces such that as the two crane components are brought close to their operational position during an assembly operation, the engagement member and the alignment surface of the connectors come into contact with one another to guide the crane components into their operational orientation so that a main pin can be placed through the through-holes of the extensions of the connectors. | 08-29-2013 |

20090022545 | JOINT FOR REINFORCED CONCRETE PILE SECTIONS - The invention relates to providing a stiff pile splice ( | 01-22-2009 |
20090263189 | JOINT FOR REINFORCED CONCRETE PILE SECTIONS - The invention relates to providing a concrete pile splice between driven reinforced concrete piles to join them together end-to-end, with the ends of both reinforced concrete piles to be joined having an end surface. The joint of each pile includes lock rods provided with pin-receiving holes, cylindrical lock sockets provided with pin-receiving through-holes to which pin-receiving tube-like parts are used to interconnect the lock sockets, and locking pins. A pair of joints forming a splice consists of two similar joint pieces. The joint is installed at the end of the concrete pile during the poured casting process. In order to reduce the cost of manufacture and materials of the splicing pieces and to achieve reliability in operation, they are made by machining or welding. Preferably, the hole ( | 10-22-2009 |

20080273923 | TELESCOPING ROD STRUCTURE FOR LINEAR ACTUATOR - A telescoping rod structure, for a linear actuator, arranged at a connecting position of a telescoping rod of a linear actuator, mainly includes a telescoping rod, a sleeve, and a connecting cap, wherein the telescoping rod is connected to a linear transmitting mechanism, and an accommodating groove passing through the telescoping rod is arranged at top of the telescoping rod; furthermore, the sleeve, arranged in the accommodating groove, is a hollow pipe piece for accommodating a connecting element to pass through; finally, the cap is a hollow lid body, the peripheral of which is arranged a plurality of corresponding projecting seats, at each of which a thorough hole is arranged such that, when the cap is fitted onto the top of the telescoping rod, it may fix the position of the sleeve arranged at the accommodating groove, in the meantime, by making the thorough holes just correspond to the hollow position of the sleeve, it being able to facilitate the connecting element to be fitted and connected securely therein. | 11-06-2008 |
20130336719 | FORWARD LOCKING PULL PIN - Provided is a pull pin that is configured to lock in a forward position to prevent accidental or undesirable retraction of the pull pin. The pull pin has a housing, a pull pin shaft, an inner shaft, a first and second spring, and at least one ball bearing. The housing has a ball locking space, which holds the ball bearing between the locking space and a ball aperture formed in the pull pin shaft to thereby lock the pull pin shaft in the forward position. Only upon the application of an external force to the inner shaft, which aligns a ball release portion with the ball aperture, can the ball bearing move into the ball release portion and thereby move out of said locking space, allowing for the retraction of the pull pin shaft. | 12-19-2013 |
20140037373 | POLE ASSEMBLY - A pole assembly includes a first mounting member defining a locking hole, and a second mounting member setting around the first mounting member. The second mounting member includes a tab operable to be bent into the locking hole to lock the mounting members together. | 02-06-2014 |
20140064842 | PUSH BUTTON-CONTROLLED RETRACTABLE BAR - A retractable bar using a positioning spring leaf and a control device to control positioning between an inner tube and an outer tube is disclosed. The control device includes a movable member, a push button, and a linking device connected between the movable member and the push button. When the push button is not pushed by an external force, the positioning spring leaf will be pushed by the movable member to force its positioning protrusions into engagement with locating notches of the inner tube to lock the outer and inner tubes. When the push button is pushed by an external force, the linking device will be forced to move the movable member away from the positioning spring leaf, causing the positioning spring leaf to disengage the positioning protrusions from the locating notches of the inner tube. | 03-06-2014 |
