1. Field of the Invention
The present invention relates generally to clasps for coupling ends of an article of jewelry together and, more particularly, to a locking toggle clasp assembly for selectively connecting the terminal ends of a chain or link bracelet, necklace or the like.
2. Description of the Related Art
Jewelry items are commonly draped or fastened about the wrist, neck or other appendage of a person to accessorize that person's appearance. Bracelets and necklaces are examples of such jewelry items. Various fastening mechanisms have been utilized to secure the jewelry item to the person wearing it.
Conventional chain or link bracelets and necklaces typically have a “closed loop” structure that can be opened to permit the bracelet or necklace to be draped about the wrist, neck or other appendage of the person wearing it. There are many types of conventional spring-operated clasps for securing the ends of chain or link bracelets and necklaces. The most widely known and used clasp is a spring ring connected to one end of the bracelet or necklace and a jump ring connected to the opposing end. The spring ring typically includes a C-shaped tubular housing containing a movable arcuate insert. The insert is normally biased by a spring to close the spring ring (i.e., to close the opening or gap in the C-shaped housing) and is selectively movable to an open position so that the jump ring on the opposing end of the jewelry item may be selectively connected to or disconnected from the spring ring.
Other conventional bracelets or necklaces include pivotally connected sections that lock together to form a closed loop configuration. A male section typically has a protruding member while a female section has a recess for receiving the protruding member. The protruding member is cooperatively positioned within the recess to lock the bracelet or necklace in the closed position.
It is desirable to provide an improved jewelry clasp assembly over conventional jewelry clasps that offers, at least, the following attributes: (1) ease of manipulation by the person wearing the jewelry item; (2) secure, positive closure; (3) compactness of size; (4) aesthetic appearance; (5) strength and reliability; (6) simplicity of construction; (7) economy of manufacture; (8) ease of assembly; (9) absence of sharp or jagged edges; and (10) application to a wide spectrum of jewelry.
A locking toggle clasp assembly is provided for releasably coupling opposing terminal portions of a jewelry item. The locking toggle clasp assembly includes a toggle bar connected to a first terminal portion of the jewelry item. A toggle clasp having an opening is connected to a second terminal portion of the jewelry item. The toggle clasp is selectively movable between an open position in which the toggle bar may pass through the opening and a locked position in which the toggle bar is prevented from passing through the opening.
The foregoing specific objects and advantages of the invention are illustrative of those that can be achieved by the present invention and are not intended to be exhaustive or limiting of the possible advantages which can be realized. Thus, these and other objects and advantages of this invention will be apparent from the description herein or can be learned from practicing this invention, both as embodied herein or as modified in view of any variations which may be apparent to those skilled in the art. Accordingly, the present invention resides in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.
Further aspects of the instant invention will be more readily appreciated upon review of the detailed description of the embodiments included below when taken in conjunction with the accompanying drawings, of which:
Referring to
The toggle bar 14 is provided at a first terminal portion or end 12 of the jewelry item 10. When in the closed or locked position, the toggle bar 14 extends generally in a plane perpendicular to the central axis of the jewelry item 10. The locking toggle clasp 18 is provided at a second terminal portion or end 16 of the jewelry item 10. The toggle bar 14 and locking toggle clasp 18 may be attached to the opposing terminal portions or ends 12, 16 of the jewelry item 10 in any known conventional manner.
As will be discussed in greater detail below, the locking toggle clasp 18 is selectively moveable between an open position (depicted in
Thus, if the jewelry item 10 is draped around an appendage of the person wearing it, the toggle bar 14 is passed through the opening 24 of the toggle clasp 18, the toggle clasp 18 is then moved to its closed or locked position, and the jewelry item 10 is conveniently secured or locked around the appendage of the person wearing it. Similarly, to remove or unlock the jewelry item 10, the toggle clasp 18 is moved to its open position and the toggle bar 14 may be passed through the opening 24.
Similarly, the toggle clasp 18 is attached to the second terminal portion or end 16 of the jewelry item 10 in a conventional manner. For instance, in a preferred embodiment, the locking toggle clasp 18 is preferably attached to a link or loop 34 at or near the second terminal portion or end of the jewelry item 10. If desired, a decorative second end cap 22 having the link 34 may be provided at the second terminal portion or end 16 of the jewelry item 10. Other well known means may be used to connect the toggle bar 14 and toggle clasp 18 to the opposing ends of the jewelry item 10.
In the preferred embodiment, the locking toggle clasp 18 includes a toggle loop 38 and a swivel 40 pivotally connected to the loop by means of a pin 42. The toggle loop 38 defines an opening 24. The swivel 40 is selectively moveable between an open position and a closed or locked position. In the closed or locked position, the swivel 40 impinges into and blocks a portion of the opening 24 in the toggle loop 38 such that the toggle bar 14 is not able to pass though the opening 24. The swivel 40 is held in the closed or locked position by friction created between contact surfaces on the swivel 40 and the toggle loop 38.
In a preferred embodiment, the toggle bar 14 is larger than the opening 24 of the toggle loop 38 in a first dimension (major dimension) along a first axis and smaller than the opening 24 of the toggle loop 38 in a second dimension (minor dimension) along a second axis. In this manner, the toggle bar 14 is able to pass through the opening 24 in the toggle loop 38 when the swivel 40 is in the open position, but is prevented from passing through the opening 24 in the toggle loop 38 when the swivel 40 is in the closed position.
Since the toggle bar 14 is smaller than the opening 24 in the second (minor) dimension, the toggle bar 14 may be inserted through the opening 24 along the axis corresponding to the second dimension when the swivel 40 is in its open position (i.e., not impinging into the opening 24). When the swivel 40 is pivoted to its closed position, however, the swivel impinges into and blocks a portion of the opening 24 in the toggle loop 38 to prevent the toggle bar 14 from passing through the opening 24. The swivel 40 is releasably held in the closed or locked position by frictional engagement between contact surfaces of the toggle bar 14 and swivel 40. The toggle bar 14 cannot pass through the opening 24 because the toggle bar is larger than the opening 24 in at least the first (major) dimension and the opening 24 is not large enough to permit the toggle bar 14 to pass through it along the axis corresponding to the second (minor) dimension when the swivel 40 is in its closed or locked position.
Although an illustrative preferred embodiment has been described herein in detail, it should be noted and will be appreciated by those skilled in the art that numerous variations may be made within the scope of this invention without departing from the principle of this invention and without sacrificing its chief advantages. For example, it is understood that the opening 24 and toggle loop 38 need not be curved or round, and that other shapes can be utilized in accordance with and within the scope of this invention. The terms and expressions have been used herein as terms of description and not terms of limitation. There is no intention to use the terms or expressions to exclude any equivalents of features shown and described or portions thereof and this invention should be defined in accordance with the claims that follow.
