A cleat for a boat includes a cam mounted to the boat, where the cam has a rotatable toothed surface for pressing against a line. The cleat also includes a guide mounted to the boat adjacent the cam, where the guide has a surface for directing the line above a top of the cam. In addition, the cleat has a slot formed in the surface of the guide, which permits the line to be moved into opposition with the rotatable toothed surface of the cam.

A directional lock or a headgear or interface assembly comprising one or more directional locks that include a catch arrangement for initiating or assisting in movement of a lock member of the direction lock. In some configurations, the catch arrangement assists movement of the lock member in only a portion of a range of travel of the lock member. In some configurations, the directional lock has a housing and a sleeve and the catch arrangement has a catch arm carried by the sleeve. The catch arm includes a catch end that contacts the lock member, which can be a lock washer in some configurations.

A fall protection device or cable grab device for use with a generally vertically-extending cable, comprising: an articulating frame comprising: (i) a plurality of members; (ii) a channel configured to receive and retain the cable; and (iii) an attachment member opening extending through at least a portion of the articulating frame and configured to facilitate attachment of an attachment member to the cable grab device; wherein, when the frame is articulated in a generally downward (or first) direction, and at a specified point, at least a portion of at least one of the plurality of members contacts the cable and brakes movement of the cable grab device; wherein, when the frame is articulated in a generally upward (or second) direction, and at a specified point, at least a portion of at least one of the plurality of members contacts the cable and brakes movement of the cable grab device.

A buckle connector and a chest expander using the same. The buckle connector includes a male buckle (1) and a female buckle (2) fit with each other. The male buckle (1) includes a connecting portion (11). The connecting portion (11) includes a clamping member (13). The female buckle (2) is provided with an opening (21) for inserting the clamping member (13). The opening (21) extends towards the interior of the female buckle (2) and forms a groove (22) for accommodating the clamping member (13) along a circumferential direction. An elastic member is provided in the groove (22). A protruding portion (24) for preventing the clamping member (13) from passing through is provided on the elastic member. When a torque is applied to the male buckle (1) so that the clamping member (13) rotates in the groove (22) and passes through the protruding portion (24), the clamping member (13) squeezes the protruding portion (24) and causes the protruding portion (24) to retreat to allow the clamping member (13) to pass through. After the clamping member (13) passes through the protruding portion (24), the protruding portion (24) returns to a position before squeezed. In the buckle connector, the male buckle (1) is inserted into the female buckle (2) from the opening (21), and then the male buckle (1) is rotated, so that the clamping member (13) rotates in the groove (22), and thus the clamping member (22) is clamped by means of the horizontal groove in the female connector, achieving the effect of connecting the male buckle (1) and the female buckle (2) conveniently and easily.

A wedge clamp for a rope includes two clamping wedges extending in a longitudinal direction. The clamping wedges are accommodated in a clamping housing in an assembled state. The clamping wedges have a channel extending in the longitudinal direction for clampingly receiving the rope. A groove extending in the longitudinal direction is provided in the channel. The groove is preferably used to adjust transverse compressive forces during tensioning, so that the wedge clamp is also suitable for ropes with a pressure-sensitive core. A tensioning device for tensioning a rope is also provided.
