This disclosure pertains to a lockdown mechanism for an electric drive screw telescoping mast. The lockdown mechanism comprising a plurality of elongated tube sections which are telescopingly attached to each other, each tube section comprising a substantially hollow body. An elongated drive screw is disposed within the hollow body and includes a plurality of threads for extending and retracting the elongated tube sections. A lock subassembly includes a housing and a center hub, the housing comprises a load bearing top and a hollow cavity, the lock subassembly being rigidly attached to said center tube and axially aligned along a central axis with said plurality of elongated tube sections. The center hub is movably engaged within the hollow cavity of the housing and includes at least one locking pin adapted to the center hub that is movably engaged to the structural envelope when the mast is in the lockdown position.

Support de roue pliable permettant la mise en place ou l'escamotage des roues de hissage des bateaux notament par mer forte sans démontage ni remontage et un gain de place dans le bateau. Il comprend: un tube carré (1) fixé au bateau sur lequel s'articule les tubes carrés (5) et (6) solidaires porteurs de la roue. Un autre tube carré (10) s'insère à l'intérieur des tubes (1) et (5) permettant de laisser jouer l'articulation ou de maintenir ces tubes en prolongement. L'extraction partielle et l'accrochage du tube (10) permet le pliage du support au moyen d'une corde (18) ou d'une poignée (27). Sa réinsertion permet l'accrochage en position pliée. Une nouvelle extraction partielle du tube (10) permet le dépliage avec la même corde.

Embodiments of the invention provide a locking retainer 20 for a slidable support that includes a two support member 48 with respective sets of locking apertures 50, 52, with the two support members slidably engaging each other to define a support profile. A strap 22 can at least partly bound an internal area and can include a locking pin 38, 40 that extends into the internal area. The strap can have a locking configuration in which, with the slidable support disposed within the internal area, the locking pin extends into two of the locking apertures to lock the slidable support at a fixed length. A locking retainer can be installed by disposing the slidable support within the internal area, aligning two locking apertures of the slidable support, and applying lateral pressure to a side arm 26, 28 of the locking retainer to seat a locking pin in the aligned locking apertures.

A power tool coupling system for coupling two boom members (14,16) of a split-boom power tool (10). The coupling system includes a first section (44) and a second section (46). The first section is adapted to be fixedly attached to an end of a first one of the boom members. The first section includes an aperture (60) for receiving a locating member (38) on a second one of the boom members. The second section is movably connected to the first section. The second section is adapted to depress the locating member, while the locating member is located in the aperture of the first section, when the second section is moved from a first to a second position.

An adjustable height bicycle sea post assembly (20) comprises a hollow seat post (22) for supporting a bicycle seat (40) slidably supported on plastic shims (42) inside a hollow tube (24). The tube (24) clamps into the frame (31) of a bicycle (34). A main spring (76) forces the post (22) upward, but a locking mechanism (28) interconnects the post (22) with the tube (24) in various fixed positions relative to the tube (24). The locking mechanism (28) includes a foundation (80) and a projection (82) extending from the foundation (80) having a counterbore (86) for guiding a plunger (88) into holes (102) on the post (22). The locking mechanism (28) adheres to the outside of the tube (24) to bear shearing forces on the plunger (88). An endcap (132) on the locking mechanism (28) and a top cap (50) on the tube (24) protect the assembly (20) from foreign debris. The locking mechanism (28) may be manipulated remotely using a magnetic switch (29) or manually using a manual assembly.
摘要:
A connecting member for releasably connecting a first part to a second part is provided. The connecting member includes a housing and a first locking member. The housing has a first opening and a second opening. The first locking member has a first tab and a first button. The first locking member is in the housing such that the first locking member biases the first tab through the first opening and the first button through the second opening. The first tab is releasably connectable to the first part over the housing when the first tab is biased through the first opening. Further, the first button remains uncovered by the first part when the first part is releasably connected to the first tab.
