A clasp comprising a piston member, cylinder member, and a member for attaching and detaching said piston member to the cylinder member. The clasp of the present invention comprises an elastic member which apply a resilient force to the piston member in the direction that the piston member is separated from said cylinder member; a lock pin projected on either surface of the piston member and the cylinder member contact with each other in substantially vertical direction to the remaining surface so that projection elastic force is applied in a movable manner: a W-shaped or M-shaped guide groove including a concave portion for inserting the lock pin and having a route for directing the movement of the lock pin, which comprises a first bent portion, a second bent portion, and a third bent portion from the inlet and outlet of the route; and a member for directing the movement of the lock pin.

The invention relates to a holder (1) for receiving an object (8) provided with a button (7), such as a cellular telephone. The holder (1) is provided with a receiving passage (5) for receiving the button (7), a resilient stop (10) for securing the button (7) in the receiving passage (5) when the object (8) provided with a button (7) is arranged in the holder, and a device for releasing the resilient stop (10), comprising a push button (12) located opposite the opening of the receiving passage. The holder (1) is characterized in that the releasable stop (10) and the push button (12) is one integral unit (13) which is pivotally arranged about an axis of rotation in the holder, wherein at least one resilient element is provided for countering rotation of the integral unit (13). Moreover the push button (12) is so arranged relative to the axis of rotation, that the resilient stop (10) may be released by pushing the push button (12).

An interchangeable setting for a jewelry piece for displaying an ornament comprises a holder for supporting the ornament and prongs on the holder for securing the ornament. The holder have a cylindrical extension having projections for insertion into a receiver. The receiver has walls defining a cavity for removably receiving the holder. At least one groove is provided on an inner wall defining the cavity of the receiver for detachable engagement with the projection of the post for detachably securing the holder to the receiver. The upper surface of the groove is angled to insure wobble-free engagement of the holder and the receiver.

An axial locking device having two separable members which can be locked together and unlocked by relative axial movement of the two members in one direction. A slider is incorporated in one of the members and is movable relative to the member against a spring when the two members are moved axially relative to one another in one direction. The slider is displaced in one angular direction by interengagement of mutually engageable teeth on the one member and on the slider each time the slider is moved axially. This angular displacement of the slider locks the two members together when they are first pushed axially together against the force exerted by the spring on the slider and then unlocks the two members when they are subsequently pushed axially together against the spring force to permit one handed and/or speedy operation of the locking device.

A portable two-part fastening device having a female section including a keyhole, a spring within the female section, and a ridge supported by the spring, an open channel in the female section contiguous with the narrow dimension of the keyhole, and means for mounting the female section to one part of the device. A male section comprises a button larger than the keyhole but having a width less than the open channel, with a flattened stud connecting said button to the other part of the two device. The button has an indentation on the outer face thereof of a geometrical configuration so as to mate with the ridge on the spring. The narrow dimension of the stud has a width less than the narrow dimension of the keyhole whereby the button and the stud may be positioned such that the button passes through the open slot and the stud passes through the narrow dimension of the keyhole with the spring exerting a biasing force against the face of the button hole so that the button and stud are maintained within the female portion.

A quick-engageable, quick-disengageable coupling or clasp for connecting the ends of a piece of jewelry such as a necklace or bracelet. The clasp includes two initially separate longitudinal bodies end-alined in use, one body having a lengthwise projecting, inner end tongue, and the other body having an inner end slot and adapted for reception, by longitudinal insertion through the slot, of the tongue; the clasp being particularly characterized by the inclusion of instrumentalities operative, without more, to secure the tonque in the other body and thus quick-engage the clasp upon the tongue being so inserted, and to release the tongue upon relative rotation of the bodies and thus quick-disengage the clasp.

Mating fasteners having a convex receiving surface and a concave inserting surface rotationally symmetrical about an insertion axis. A key code of annular projections and grooves is located in a plane normal to and concentric with the insertion axis. A locking mechanism engages the mating pieces only when in mating relation as determined by the key code. A planar embodiment is included. Easy and accurate assembly or connection becomes much less critical.

A fastener for connecting two parts of a flexible ornamental article comprises a sleeve, which is open at both ends and provided with first bayonet joint means adjacent to each end thereof, two plugs, each of which is provided with second bayonet joint means which are contained in said sleeve and interengage with said first bayonet joint means, and a helical compression spring contained in said sleeve between said plugs and urging said plugs axially apart. Each of said plugs is rotatable in said sleeve to disengage said second bayonet joint means of said plug from the first bayonet joint means and is subsequently axially movable out of said sleeve. The fastener can be used to connect two parts of a flexible ornamental article if each of said parts is provided with one of said plugs.
