Abstract: A bodkin includes first and second holding plates, an operation plate and an elongated bar member. The second holding plate overlaps with the first holding plate. The operation plate is rotatably supported by the first holding plate with a part of the second holding plate disposed between the first holding plate and the operation plate. The bar member is connected to the first holding plate so that the operation plate is operable independently of the bar member. Use of the operation plate enables the bodkin to selectively take an opened state and a closed state. In the opened state, the two holding plates are apart from each other, providing a gap into which an end of a string can be inserted. In the closed state, the two holding plates are brought closer to each other, thereby pinching the end of the string between them.

Abstract: A clip for a yoga mat which secures a towel to the mat. The clip has a frame portion along with a cam lever or actuator. A user of the device rotates the cam lever about an axis from a first position to a second position. As the cam lever is rotated toward the second position, a portion of the cam lever makes contact with a movable portion of the frame. The cam lever forces the movable portion from a top location toward a bottom location which shortens a space between two members of the clip. The towel and mat are secured when the device is in the second position.

Abstract: A locking mechanism for joining an elongate member to an assembly may include a frame, clamp, actuator and link between the clamp and actuator. Stop surfaces on the clamp and actuator cooperate to secure the elongate member. A pin and the force transmitted by a compression spring may further be provided for additional security. The link between the clamp and actuator retracts the clamp permitting the elongate member to be detached from the assembly. A linear actuator may be operatively disposed between the frame and the actuator for opening and closing the clamp about the elongate member.

Abstract: A locking device includes: a pivot rod extending through a connecting block of a U-shaped seat and through a connecting block of a rotary cover such that the rotary cover is rotatable relative to the seat between unlocking and locking positions; a resilient member for biasing the rotary cover to move toward the locking position; and a position-limiting unit including a guiding groove formed in one of the connecting block and the pivot block, and a guiding rod provided on the other one of the connecting block and the pivot block, and extending into and engaging movably the guiding groove. When the guiding rod is limited and engaged in one end of the guiding groove, the rotary cover is positioned at the unlocking position, where the rotary cover is spaced apart from the seat.

Abstract: A clip assembly adapted to engage a male track member. The clip assembly includes a clamshell clamping member including a first leg and a second leg. The clip assembly further includes a female compression member adapted to fit in sliding relation at least partially about the clamshell clamping member. The female compression member is adapted to compress the first leg towards the second leg.

Abstract: The clamp is of the type which may be actuated by means of an auxiliary actuating member. It consists of two parts, namely a clip (1), whose two branches are connected via a thin part (7) and a slit housing (8) in which an actuating member (2), consisting of a pin with a diameter greater than the diameter of the housing (8) or a cam equipped with a radial arm, is accommodated. The introduction of the pin or, respectively, the rotation of the cam results in closure of the clip, causing the thin part (7) to bend resiliently.

Abstract: A fastening device for securing, for example, two pieces of fabric together comprises an outer body and an outer body secured in the outer body for rotational and axial movement relative thereto so that the inner body can move outwardly and inwardly of the outer body. The inner body carries a securing element in the form of a hook or spiral so that when the inner body is moved out of the outer body the securing element can be engaged in, say, the two pieces of fabric which, when the inner body is moved axially inwardly, are trapped between the securing element and the outer body.

Abstract: A hinge device comprising a main body in the form of a channel member, a mount pin projecting outward from the web of the main body, and a pressing plate pivoted at its one end to the inner side of one side wall of the main body and retractable into the channel of the main body, the pressing plate being provided with a wedge formation on one side surface thereof opposed to said one side wall of the main body so as to gradually approach the other side wall of the main body as the pressing plate is retracted into the channel of the main body. A plate, such as the closure plate of a cabinet, can be loosely fitted into the channel of the main body with the pressing plate withdrawn therefrom and can be tightly held in the channel by the wedging effect produced when the pressing plate is retracted. The hinge device can be installed in place easily and yet holds the plate reliably.

Abstract: A coupling for clamping metallic scaffold tubes has two levers pivotally mounted on a common hinge and arranged to be locked by a wedge when they surround the scaffold tube. One of the levers is provided with a second hinge pivotally supporting a yoke which in turn supports the wedge. The thickened formations are provided on two opposite faces of the bars constituting the yoke, the formations preventing the wedge which is formed of sheet metal from slipping out of the yoke.
