摘要:
A system for verifiably locking a first cylindrical component to a second cylindrical component in a safe and secure manner. The system provides a visible indication when the first component and second component are fully and effectively secured. The first cylindrical component comprises a lock cylinder fixedly attached to the first cylindrical component. The lock cylinder comprises a lock piston. The second cylindrical component comprises a channel with a guide region and a lock region. The visible portion of the lock piston provides an indication of whether or not the lock piston is secured in the lock region of the channel. The system is also capable of being operated from a control panel to operate the locks, receive signals from sensors, and to display the lock status of the system. The system offers redundant verifications to enhance safety in operating environments.

Die Erfindung betrifft eine Zug-Druck-Stange (1), aufweisend: - einen hohlzylindrischen Mittelkörper (2); - zumindest eine Befestigungsvorrichtung (3, 4) mit einem Kupplungselement (5, 6) und einem daran angeordneten Schaft (9, 10); - zumindest ein Anschlussstück (7, 8), wobei die Befestigungsvorrichtung (3, 4) zur Längenveränderung der Zug-Druck-Stange (1) über eine Gewindeanordnung (24, 25) drehbar mit dem Anschlussstück (7, 8) verbunden ist;
wobei mindestens eine der Gewindeanordnungen (24, 25) eine schraubenförmig gewundene Stahldrahteinlage (11, 12) aufweist, die zwischen dem Anschlussstück (7, 8) und dem Schaft (9, 10) angeordnet ist.
摘要:
A turnbuckle (10) is made by a method including preparing an iron tube (40) having a longitudinal through-hole (42). A diameter of each of two ends (50) of the iron tube (40) is reduced to form a coupling section (12) having an engaging hole (121), with an interconnecting section (11) interconnected between the coupling sections (12). The interconnecting section (11) is punched in a direction perpendicular to the longitudinal through-hole (12) to form a transverse through-hole (13) perpendicular to the longitudinal through-hole (42) and between the coupling sections (12), leaving two opposite peripheral wall portions (44) spaced by the transverse through-hole (13) and forming a bend (14) extending inward from each of two end edges (46) of each peripheral wall portion (44) into the longitudinal through-hole (42), An abutting portion (15) is formed between each bend (14) and one of the end edges (46) of one of the peripheral wall portions (44). Inner threading is formed in the engaging hole (121) of each coupling section (12).

A wheelchair is provided which has a seat height adjustment comprised of a double in-line turnbuckle that allows infinite adjustment of the length of a turnbuckle assembly. The assembly includes a handgrip with a longitudinal recess having a first end with smaller internal threads that mate with the external threads of a smaller diameter cylinder. This cylinder can telescope with a recess formed in a second hollow cylinder having oppositely threaded external threads that mote with a second larger diameter set of threads in a second end of the longitudinal recess of the handgrip. The smaller diameter cylinder includes a snap button on a leif spring, which catches an annular shoulder on the recess formed at the transition between the smaller and the larger diameter areas. This inhibits the turnbuckle from over-extension. Further, the assembly has a restraint, which inhibits the turnbuckle assembly from working out of its selected position during use. The restraint can be pop detent or jam nut. The turnbuckle assembly is pivotally mounted at both ends in brackets, which are fastened respectively to a seat frame member and to a cross frame member.

The invention relates to a tension rod comprising an anchor head (1) with a threaded bore hole into which the end of a tension rod with an outer thread can be screwed. A sealing nut (8) is joined to the front side of the anchor head (1). Said nut has an inner rod seal (12) that seals the flat cylindrical outer surface (7a) of the tension rod (7) when screwed. The sealing nut (8) is sealed off from the anchor head (1). The inner end of the threaded bore hole is also sealed.
