1. Field of the Invention
This invention relates to a carabiner, and more particularly, to a carabiner in the form of a C-shaped structure having an articulated gate member which may be opened and closed to form a secure, hook-like hanger or carrier for a plurality of articles.
2. Description of the Prior Art
Carabiners have long been used in climbing, for example, to hang and hold ropes from used in the climbing process, as shown for example shown in U.S. Pat. Nos. 4,095,316; 4,811,467; 5,005,266; 5,329,675; and 6,606,769; and 6,622,354.
Recently, the function of a carabiner has been expanded to hang articles from a clothing belt, such as keychains, restrain dogs on a leash, or even hang packages, diaper bags, camera bags, or shopping bags from a mobile vehicle such as a baby stroller, shopping cart, or the like, having a cylindrical handle. However, the carabiner has the tendency to slip from side to side on the handle, under the weight of the article being hung from the carabiner and/or because of the motion imparted to the held article. While U.S. Pat. No. 6,606,769 shows a webbing sewn around the bottom straight portion of a carabiner to preclude slippage of an article, such as a dog leach strap attached to it, it does not teach the use of an anti-slip device on a carabiner attached to a cylindrical or tubular handle on which the carabiner is mounted or attached. Such a device would preclude shifting of the load held on the carabiner and damaging the load and possibly hitting a child in the stroller or shopping cart or the person using the mobile vehicle.
Accordingly, it is the object of this invention to provide an economical, simple to manufacture, easily adjustable, non-slip device on an apex, or load supporting portion of a carabiner which is adapted to be hung universally on different types of round-handled carriers in order to provide security and safety for a person needing to hang items from the carrier.
This is accomplished by forming the carabiner with an apex on the upper end of the C-shaped, gated carabiner, forming a discrete load bearing surface for hanging the carabiner from a rounded handle on the carrier and covering the apex with a non-slip rubber sleeve. The sleeve fits over the apex of the carabiner, which then hangs on the carrier handle and with the hung load, frictionally prevents side to side movement of the carabiner along the handle. In one specific embodiment, the sleeve extends substantially to the pivot of the hinge of the carabiner, to ensure its extended frictional engagement with the support member on which the carabiner is reposed.
Alternatively, the sleeve can extend from the apex adjacent the gated member to cover the other leg of the C-shaped carabiner to prevent non-slippage of the items hung on the carabiner.
In another embodiment, the rubber sleeve can also be provided with finger grips, so the carabiner may function as a carrying handle or used in the conventional manner to hang articles, but with a finger grip at the apex to prevent slippage as the finger grip “cups” the handle.
Of course, it is possible to use the carabiner on handled carriers whose handles are non-rounded or provided with irregular shapes, such as pegs mounted on a wall and the non-slip material may be a suitable plastic. Even a knurled surface formed on the underlying metal of the carabiner is within the scope of the invention.
Referring now to the drawings in detail, wherein like numerals indicate like elements throughout the several views,
As shown, carabiner 10 is formed of an essentially C-shaped member 12, and includes a gate member 14, articulated about a pivot pin 16. C-shaped member 12 and gate member 14, when gate member 14 is in closed position as indicated in
A rubber sleeve 22 extends about the C-shaped member 12 from a point adjacent to pivot pin 16 and encompassing at least the apex portion 18 of the member 12 as shown in
If desired, the sleeve 22 can extend about the bottom portion 24 of the C-shaped member 12 to further preclude slippage of the items loaded onto this portion of the carabiner 10, as shown in
Further, as shown in
During manufacture, the sleeve 22, may be slid on the apex portion 18 by opening the articulated gate member 14, by pivoting the member 14 inwardly about pivot pin 16 and sliding the sleeve 22 along the tubular or cylindrical gate member 14, until fully seated on the C-shaped member 12. The upper and lower opposed ends 28, 30, respectively, of the C-shaped member 12 are flattened to receive the tubular end 32 of gate member 14 and pivot pin 16 therethrough. A leaf spring 34 is received in tubular end 32 and in the end 28 of C-shaped member 12 on a bias or angle between the ends 28,30 so that when the gate member is opened inwardly about the pivot pin 16, the leaf spring 34 will exert a force on the tubular gate to return it to a closed position where the opposite end 36 having a pin 38 therethrough of the tubular gate member 14 is received beneath a flattened hook 40 extending above end 30 of C-shaped member 12 to latch the gate member 14 in closed position under the urging of leaf spring 34.
