A cord lock for a Venetian blind or a shade disclosed has a housing having two parallel sidewalls, and spaced end walls, an inclined downwardly facing surface of one end wall in the nature of a ramp is formed with a plurality of transverse teeth or serrations. An opening is formed by the sidewalls, the end walls and the downwardly facing surface of the other end wall. A separator extends between the end walls. A pulley roller is rotatably mounted on a shaft supported in the sidewalls. A cylindrical floating roller is formed on its peripheral surface with a plurality of teeth or serrations extending in a direction parallel to own axis. A top opening is provided through which lift cords may pass freely to the pulley roller and then through the opening and then through different sides of the separator and then be completed as free hanging ends of pull cords. A pusher is placed on the housing and makes mechanical contact with the pull cords for always pushing the pull cords towards the cylindrical floating roller permanently. The pusher insures the immediate and automatic locking of the cords if the pull cords are accidentally released or dropped.
A remotely actuatable latch for locking and releasing an object at a location remote from a user includes a sheave mounted at the remote location for free rotation about an axis. A line is engaged with the sheave and has one end coupled to an object to be selectively locked or released at the remote location and an opposing end that can be gripped and manually manipulated by a user at a location spaced from the remote location. A shackle connects the object to the line. A pendulum at the remote location is pivoted for movements between a stable position and an unstable position and positioned along the path of movement of the line and shackle when a user pulls or releases the opposing end. The pendulum has a cam surface for deflecting the pendulum responsive to movements of the shackle along the path of movement past the pendulum towards the sheave to cause the shackle to ride along the cam surface thereby angularly pivoting the pendulum from the stable rest position to the unstable position. The pendulum has an engaging mechanism for engaging the shackle and has a natural period of oscillation selected to require a time τ to move from the unstable to the stable positions, whereby release of the line to allow the shackle to free fall past said pendulum with a time less than τ allows the shackle to clear the pendulum and unlock the object while controlled release of the line to move the shackle with a time sufficiently greater than τ causes the pendulum engaging mechanism to engage the shackle and fixedly secure the object to the pendulum, whereby a user can lock or unlock the shackle and therefore also the object at the remote location by controlling the speed of release of the line.

WALL-MOUNTED SLIDING STORAGE ENCLOSURE WITH FAIL-SAFE POSITION FIXING MECHANISM
A sliding storage system includes a vertical rod having upper and lower ends. Brackets attach the upper and lower ends of the rod to a wall to fix the rod in a vertical orientation. a storage device in the form of a rigid cabinet slidably is mounted on the rod for free sliding movements between (i) the lower end of the rod for positioning the storage device in a lower position to provide access to a user and allow the user to place an object on or remove an object from the cabinet and (ii) the upper end for positioning the storage device in a storage position generally above the living space of the user. A locking member in the form of a clutch plate cooperates with the cabinet and the vertical rod, the clutch plate being movable between a locking position for locking the cabinet against vertical movements along said rod and a releasing position enabling the cabinet to selectively and freely move vertically upwardly and downwardly along the rod. A spring acting between the cabinet and the clutch plate normally urges the clutch plate to move to the locking position. A manual release is actuatable directly by a user or indirectly by a line extending over a sheave above the rod to move the clutch plate from a locking position to a releasing position when manually actuated by a user to overcome the action of the spring, hi this way, manual activation of the manual release allows a user to selectively raise or lower the cabinet to place an object on or remove an object from the cabinet in a lowered position and to store an object in a raised position of the cabinet.

A portable gymnastic device comprising a suspension means having two opposed and complementary rigid hooks, which are pivotally connected together and to a U-shaped frame by a pin. Hooked upper ends of the hooks are engaged over a horizontal cross member of the doorframe or a horizontal bar. The hooks are normally biased to a closed position permanently by the spring. A rope is connected with the U-shaped frame by a knot, which is placed on a top end of the rope. A handle is connected with a bottom end of the rope by a bottom knot. On the bottom end of the rope can be placed several handle on different levels by several bottom knots.

FAILSAFE SYSTEM FOR RAISING AND LOWERING AT LEAST ONE OBJECT
A cleat with automatic line-locking, includes a frame having proximate and remote sides and formed with a passageway, extending between the proximate and remote sides, for receiving a line for movement along a first line moving direction from the proximate to the remote sides and an opposing line pulling direction from the remote to the proximate sides, and defining a line bearing surface or limit stop on one side of the passageway for limiting excessive transverse movements of the line in a direction to the one side of the passageway. Fasteners attach the frame to a support surface. A cam is provided on the frame on the other or opposite side of said passageway and has a line engaging portion normally spaced a predetermined distance from the line. The cam is movable between a line releasing position and a line locking position and is arranged to normally disengage from the line, engagement of the line by the cam to the line locking position while advancing the line in the first line moving direction creating a force couple that wedges the line between the line bearing surface or limit stop and the cam that tends to arrest or stop the line relative to the frame fixed on the support surface. The cam is formed of generally flat sheet material defining a cam plane and the line engaging portion being formed of a plurality of generally flat pressure-engaging segments or pressure pads that are angularly offset to opposite sides of said cam plane and together generally defining a line-receiving region having a generally uniform cross-section configured to frictionally engage the line in the line locking position. Auxiliary sheave assemblies may be used to provide automatic failsafe operation by means of the cleat when raising or lowering an object on a hook or loop. A pusher may be used to urge the line to move in the direction of the cam especially when the line is released.
