A window curtain pull cord concentrator safety device of the present invention provides a concentrator device which enables the gathering together of the free ends of a plurality of pull cords of a window curtain set, and enables complete transmission of a pulling force in an emergency. And basically comprises a drag cup, an inner bottom of a concave cavity of which is provided with a through hole enabling a wire hoop body coupled to a pulling member to penetrate therethrough. The wire hoop body is located in the interior of the drag cup, and displacement of an inner loop side of the wire hoop body relative to the drag cup is used to determine whether the free ends of the pull cords are radially restrained, thereby enabling complete relay transmission of the pulling force. In an emergency, the pull cords are rapidly released, thereby achieving instantaneous prompt safety effectiveness.

A belt end connection for fastening a support belt end in an elevator installation and a method for protecting and checking a belt end connection in an elevator installation includes a twisting prevention device that prevents twisting of the belt end connection about the longitudinal axis thereof. A wedge retains the support belt end in a wedge pocket and is secured by a loss prevention device against slipping out of the wedge pocket. The twisting prevention device and/or the loss prevention enable efficient protection of the support belt and/or of the belt end connection against damage and make possible efficient checking and control of the belt end connection.

A cable clamp may be constructed from a hollow body, a wedge-shaped member and a means for dislodging the member from the body. The body includes a tapered channel that is sized and shaped to accommodate the member and round, flat or rectangular cable sections. The means for dislodging the member include an aperture extending from one side of the member to the other, at least one cylindrical bearing surface positioned at the upper end of the body, and a camshaft. The camshaft has at least one cylindrical end with an inward facing end and an outward facing end. A cylindrical shaft in orthogonally and eccentrically mounted to the inward facing end. The camshaft is positioned so that the cylindrical shaft will bear against the inner surface of the aperture and the end portion will bear against the bearing surface. When the camshaft is rotated, the cylindrical shaft will cause the aperture and the wedge-shaped member to be displaced upwardly from the body. Standard means for rotating the camshaft include: standard screw slots, Phillips screw slots, hex nut connectors, Allen sockets, Torx sockets, and square socket connectors. In a variant, a separate, removable dislodging tool may replace the camshaft as may a captive camshaft that has only a single cylindrical end portion constrained within the upper end of the body. Other variants include means of attaching the body to objects, including wire bails, holes in the body and hooks. Means of connecting the member to the wire bail are provided.

A cable socket wedge has two wedge halves held apart by at least three blocks, such that cutting the blocks allows the wedge halves to collapse inward, loosening the wedge and cable in the socket. Crushable inserts are located in the spaces between adjacent pairs of the blocks, between the wedge halves so as to provide sufficient crushable volume to allow the wedge halves to move toward each other when the blocks are cut. The wedge is employed with a socket having a window therein. The window is positioned in the socket such that, with a properly sized cable and wedge, the central of the three blocks is accessible through the window in the socket when a cable is secured and tightened with the wedge in the socket.

A two part rope lock for hooking over the railing of a boat, having a hanger member with a pair of transversely arranged guide hooks at upper and lower ends. A channel is formed by two outstanding flanges at the back of a leg of a rail-engageable hook between the guide hooks for passage of a rope therethrough. The flanges include inclined slots for the slidable non-pivotal attachment of a cam wedge second member that moves at an inclined angle toward the leg of the hanger member. Both the hanger member and the cam wedge member include serrated surfaces so that when the cam wedge is slid downwardly a rope may be clamped therebetween. The rope lock is adjustable by one hand so that the rope may be adjusted to be gripped at different positions, such as for use with a bumper guard attached to a depending end of the rope for placing the guard at different locations on the hull of a boat as needed.

Clamping means for a strap comprises a support member having a concave surface and a guide member having a convex surface. The guide member is pivotally mounted on the support member for angular movement between a first position in which the concave and convex surfaces are spaced apart by a distance greater than the uncompressed thickness of the strap and a second position in which the concave and convex surfaces are spaced apart by a distance less than the uncompressed thickness of the strap. The guide member further comprises a lobe so positioned in relation to the convex surface that the length of the path of the strap extending from a first predetermined location, round the lobe and between the concave and convex surfaces (24, 48), to a second predetermined location decreases as the guide member pivots from its first position to its second position.

A restraint belt guide loop assembly for deflecting a belt from a retractor to a diagonal position across the occupant upper torso includes a mounting bracket pivotally mounted on the vehicle body and first and second belt clamping bars independently pivotally mounted on the mounting bracket and being eccentrically shaped to define belt clamping faces which are movable toward and away from each other upon rotation of the belt clamping bars. The first belt clamping bar has an associated reaction arm which is traversed by the belt so that imposition of an occupant restraint load on the belt induces forced rotation of the first belt clamping bar. A linkage interconnects the first and second belt clamping bars to simultaneously force rotation of the second clamping bar in a direction toward the first belt clamping bar to thereby move the respective eccentric belt clamping faces of the first and second belt clamping bars into belt clamping proximity with each other to clamp the belt therebetween against further movement through the guide loop assembly. A spring is preferably provided to establish the belt clamping bars in their respective normal positions in which the eccentric belt clamping faces are spaced apart to permit free sliding movement of the belt through the guide loop assembly.

A carrier for supporting a panel for movement along a track and adapted for connection to a string for controlling the spacing of the carriers along the track. The carrier includes a carrier body having a key receiving cavity, a locking key integrally connected to the body by a frangible connection arranged to allow an intermediate portion of a string to be inserted laterally into a position extending crosswise of the cavity. The key is then forced into the cavity to form a loop in the string and lock the string to the carrier body.
