    • The present invention relates to a descender which can be used for works at height, climbing, mountaineering, speleology or any other practice which envisages access by using a textile rope.
      More in particular, the present invention relates to a descender device for a textile rope (F), comprising a casing in which a cam mechanism (10) and an actuating lever (3) for the cam mechanism (10) are housed, wherein the casing (2) comprises a return element (13) for the rope (F), characterized in that the cam mechanism (10) comprises a lever pin (29) that can be actuated in rotation by the actuation lever (3) and a movable cam (25) which is rotatably movable in an activation direction between a deactivation position and a lock position in which the movable cam (25) presses on the rope (F) against the return element (13), and in which the lever pin (29) is configured so as to act on a rocker member (32) which is integral with the movable cam (25) during a first rotation step of the lever pin (29) in a direction opposite to the activation direction of the movable cam (25) .

    • A descender for use when abseiling down a rope, the descender including a self acting brake mechanism (63,36), which will slow the rate of descent unless the brake is held in the release position, and a manually operated braking mechanism (95,31) which will slow the rate of descent when a handle (17) is operated. The descender has two braking surfaces (36,95) in substantially fixed locations and a pair of sheaves or projections (30,31) extending from a support member (32) which is pivotable about an axis passing through a lower one of the sheaves (30) such that a rope passing around the lower sheave (30), between the two sheaves (30,31) around the upper sheave (31) and finally between the upper sheave (31) and the first of the two braking surfaces (36), will cause the pivotable member to be pivoted to press the rope between the upper sheave (31) and the braking surface (36) when a tension is applied to the upper end of the rope (15). The descender is also provided with a handle (17) to reduce the braking force by pivoting the upper sheave (31) away from the first braking surface (36) and toward the second braking surface (95). Further movement of the handle will cause the rope to be pressed between the upper sheave (31) and the second braking surface (95) to enable manual braking of the descender. The second braking surface (95) while being in a fixed location, is pivotable to allow proper alignment with the rope passing through the descender. A retaining plate (39) is also provided, which is pivotable between a position in which the rope (15) is retained in the descender and a position in which the rope is able to be inserted into and removed from the descender.
    • 下降器,当下降绳索时使用,下降器包括自动制动机构(63,36),除非制动器保持在释放位置,否则将降低下降速度,以及手动操作的制动机构(95, 31),当手柄(17)被操作时,这将降低下降速度。 下降器具有基本上固定的位置中的两个制动表面(36,95)和从支撑构件(32)延伸的一对滑轮或突起(30,31),所述滑轮或突起可围绕穿过下部滑轮的轴线 30),使得绕着所述下滑轮(30)绕过所述上滑轮(31)周围的所述两个滑轮(30,31)之间并且最后在所述上滑轮(31)与所述两个制动表面(36)中的所述第一制动表面 ),当将张力施加到绳索(15)的上端时,将使可枢转构件枢转以将绳索按压在上滑轮(31)和制动表面(36)之间。 下降器还设置有手柄(17),以通过使上滑轮(31)远离第一制动表面(36)枢转并朝向第二制动表面(95)来减小制动力。 手柄的进一步移动将导致绳索在上滑轮(31)和第二制动表面(95)之间被按压,以便能够手动制动下降器。 在第二制动表面(95)处于固定位置时,可枢转以允许与穿过下降器的绳索正确对准。 还设置有保持板(39),其可在绳索(15)保持在下降器中的位置和绳索能够插入到下降器中并从下降部件中移除的位置之间枢转。
