摘要:
A coupling arrangement for enabling fixing of a body structure member and a structure member. The coupling arrangement includes, at least two threaded tubes provided one in either end portion of a passage through a housing. The housing is fixed attachable in relation to the structure members and includes a threaded passage, wherein a threaded bolt is arranged through the passage. The threaded bolt is adapted to connect the body structure member and the structure member in a coupling position, from which coupling position the threaded bolt, via inserts, enables adjusting operation of the threaded tubes in opposite directions along the threaded bolt. Thus, the threaded tubes are adjustable to a respective fixed position by screwing the threaded bolt.

This patent is basically an Engineering design of a means to vary the length of a rod of two parts that are coupled together by an electrically operated motorized turnbuckle which can be activated remotely when it is difficult or impossible to access directly. This is accomplished by holding a wand that induces positive or negative pulses to the electrically operated motorized turnbuckle according to the direction of rotation desired for the electrically operated motorized turnbuckle to turn.

A coupling for a heavy-duty machine to be used between a boom and a stick having a working tool for quick coupling and decoupling of the stick to the boom for the exchange of tools and being operable from the cab or operator's station on the machine without requiring the need for one or more persons or machines at the coupling during the coupling and decoupling process. The coupling also includes a unique locking mechanism that can be remotely controlled to lock and unlock the coupling when they are in mating engagement. The coupling includes a male member attachable to the boom of the machine and a female member connected to the stick. The male member is pivotally mounted at one end on the boom and connected at the other end to a hydraulic cylinder on the boom for articulating the male member on the boom. The male member further includes a grabber at one end and a picker at the other end for interchangeable use to guide the joining of the coupler members. The male and female members are symmetrically constructed so that either end of one member may be aligned with either end of the other. The coupling also includes a unique locking mechanism that can be remotely controlled to lock and unlock the coupling when they are in mating engagement. Further, the coupling includes unique hydraulic couplings for connecting a source of hydraulic power from the machine to the stick that may be just mated together or provided with remotely operable locking means.

Cushion (50) for anatomical support, especially of the lumbar and cervical regions, for mounting onto backs (42) of seats (41) generally, includes a curved elastic plate (51) having longitudinal ends connected by a posterior brace formed by a pair (55, 60) of rods threaded in opposite directions that screw into an intermediately placed cylindrical scroll (63) so that it is possible to vary the convexity of the plate (51) and therefore the extent to which the cushion projects from the seat back (42) by rotation of the scroll (63) in one direction or the other. It is also possible to adjust the height of the cushion, when placed inside the seat back (42), by a special internal mechanism (51, 71, 72, 74) operated by a knob (45) placed on the outside.

A double end stud has a shank member including a central slide shank portion and threaded portions formed coaxially on both axial ends of the slide shank portion. The threaded portions are externally threaded in opposite directions. The double end stud also has a nut member carried by the slide shank portion of the shank member slidably in the axial direction but not rotatably with respect to the slide shank portion. In use, the nut portion is moved axially as the threaded portions are screwed into female thread portions of the two structural members to be connected, so that the depth of penetration of the double end stud into both structural members are optimized to ensure a high strength of connection between these structural members.

A slack adjuster linkage is incorporated in a clutch release mechanism to standardize the position of movement at which the clutch is operated to compensate for wear and changes in the clutch mechanism. The slack adjuster is axial-acting and connected in a push rod linkage or hydraulic system operating the clutch mechanism, and includes both a force responsive means such as a spring which responds to a known force and a travel responsive means such as a telescoping rod operable under predetermined force conditions.
