An attachment device is provided comprising at least one fluid filled cavity formed therein. The attachment device is preferably in the form of a carabiner in which at least a portion of the carabiner body is formed of a transparent material such that the fluid filled cavity is visible. In a preferred embodiment an indicia bearing means is visibly disposed within said cavity.
1. A device comprising a body member having at least one elongate portion, said body member comprising a first end and a second end, and a gate member having a first and a second end, one of said ends of said gate member being pivotally attached to one of said ends of said body member, the other of said ends of said gate member substantially contacting said other end of said body member when said gate is in a closed position and at least two fluid containing cavities formed in said at least one elongate portion of said device, wherein said at least two fluid containing cavities are separated from each other such that said fluids of said cavities do not intermix with each other.

This application is a divisional of application Ser. No. 10/444,225, filed May 23, 2003, U.S. Pat. No. 7,353,571, issued Apr. 8, 2008, and this application incorporates by reference herein the entirety thereof.
The invention relates generally to attachment devices having a fluid-containing cavity.
Attachment devices such as snap hooks and carabiners have long been in use for providing a means for attaching articles to each other. Such devices have numerous applications, such as for example enabling multiple articles to be secured to a backpack, purse, handbag, key chain or the like. As such, these devices are fairly ubiquitous. An example of an attachment device is a carabiner such as is disclosed in U.S. Pat. No. 5,005,266.
Fluid-filled ornamental articles are known in the art. For example, U.S. Pat. No. 4,148,199 relates to a pierced earring with liquid visible therein. U.S. Pat. No. 4,093,973 relates to a liquid filled ornamental article of jewelry containing an illumination source. U.S. Pat. No. 5,006,375 relates to an ornamental article having a transparent housing shaped into a decorative configuration having a liquid therein and a subatmospheric pressure area between the liquid and housing. However, none of the prior art liquid filled ornamental articles have the utility of providing a means for attaching articles to each other and providing an indicia bearing means on a ubiquitous useful article.
The invention provides an attachment device comprising at least one fluid filled cavity formed therein. The attachment device is preferably in the form of a carabiner in which at least a portion of the carabiner body is formed of a transparent material such that the fluid filled cavity is visible. In a preferred embodiment an indicia bearing means is visibly disposed within said cavity.
It is an object of the present invention to provide a fluid filled attachment device that is aesthetically pleasing.
It is a further object of the present invention to provide a novel attachment device that provides an interior fluid filled cavity capable of containing an indicia-bearing medium.
It is still a further object of the present invention to provide in a novel attachment device a free-floating indicia-bearing medium in said fluid filled cavity.
It is yet a further object of the present invention to provide in a novel attachment device a fixed indicia-bearing medium in said fluid filled cavity.
It is still a further object of the present invention to provide a novel attachment device in the form of a carabiner that provides an interior fluid filled cavity capable of containing an indicia-bearing medium.

Body member 10 comprises an elongated member comprising a first end and a second end and is fabricated of any material suitable for attachment devices such as but not limited to bare or coated metal, wood, rubber or plastic or combinations thereof. Gate member 20 comprises an elongated member pivotally attached at one end to one end of said body member 10. The other end of gate member 20 contacts the other end of said body member 10 when said gate 20 is in a closed position. Now referring to
Cavity 30 is formed in either or both of body member 10 and gate member 20. Cavity 30 may be formed of a depression or hollow in the material of body member 10 or gate member 20, for example where the material is formed of a nontransparent material such as metal, wood, rubber or opaque plastic and sealed with a transparent material such as but not limited to readily available plastics or acrylics, polycarbonates, polyimides, methacrylates, polystyrenes or the like such that the interior of the cavity 30 is visible. Now referring to
Fluid 35 is any suitable substance that is nonreactive when employed in conjunction with the material of cavity 30. Suitable fluids 35 include colored or uncolored liquids such as but not limited to water, oil or gel or mixtures thereof, or, as seen in
Indicia bearing device 40 is contained in cavity 30 and may be fixedly anchored within said cavity 30 (as seen in
In a preferred embodiment device 2 comprises a curvilinear body 10, body 10 comprises metal having at least one cavity 30 formed therein, said cavity 30 sealed by a transparent plastic material, said cavity 30 containing a fluid 35 comprising water and further containing indicia bearing device 40, wherein said indicia bearing device 40 is elongated and is free floating in fluid 35.
