The disclosure generally relates to a carabiner, and more particularly, to a reversibly interlocking carabiner device, wherein two carabiners can be interlocked together and used as a belt buckle with a waist belt or strap and unlocked for attaching or securing one or more objects to the waist belt or strap through the unlocked carabiners.

BACKGROUND OF THE INVENTION

Backcountry snowboarding and skiing often require a user to hike up hills carrying their boards, skis and other equipment using their hands and arms. Oftentimes, these hills are covered in snow and ice and can be very slippery. Thus, having their hands and arms free for balance and control is important for the safety of the user. Even at resort settings, carrying snowboards and skis as well as boots, gloves, helmets and other snow gear to and from a parking lot can be cumbersome, often requiring the use of both hands and arms.

Thus, to make the transportation of sporting gear and other objects more convenient and safe for the user, what is needed is a device that can secure these objects to the user such that the user may have their hands and arms free for balance and control.

SUMMARY OF THE INVENTION

The present disclosure seeks to overcome the foregoing disadvantages in an improved manner over commonly known devices. To make the transportation of sporting gear and other objects more convenient and safe, the present disclosure provides a reversibly interlocking carabiner device having a waist belt or strap that includes two carabiners at each end. The two carabiners of can be reversibly interlocked together and used as a belt buckle with the waist belt or strap and unlocked for attaching or securing sporting gear and/or other objects to the waist belt or strap through the unlocked carabiners.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure provides a reversibly interlocking carabiner device having a waist belt or strap that includes two carabiners at each end. The two carabiners of the device can be reversibly interlocked together and used as a belt buckle with the waist belt or strap and unlocked for attaching or securing sporting gear and other objects to the waist belt or strap through the unlocked carabiners. The two carabiners can be attached or secured onto various objects such that the user can sling the strap portion onto one shoulder or across both shoulders allowing the user's hands and arms to be free for other purposes. The disclosure provides a system of two reversibly interlocking carabiners that can be worn as a belt buckle when not in use, thereby converting the carrying strap to a waist belt, and vice-versa. This allows the strap to be easily accessible and readily available to the user at all times.

The two carabiners can be reversibly interlocked together in order to fit as a belt buckle and still be comfortable enough to wear without digging into the belly of the user when the two carabiners are interlocked. This is achieved by interlocking the two carabiners, one on top of the other in a parallel plane, but in opposite orientations. That is, the two carabiners reversibly interlock together in a position such that the openings or the gate of each of the carabiners face in the opposite direction thereby providing a stationary, non-moving edge on both sides of the device. In addition, the waist belt or strap may be attached at each end to one of the two carabiners through an attachment portion, wherein the attachment portion also allows the length of the waist belt or strap to be adjustable to fit the user's body size or the size of the object to be carried.

The disclosure further provides a mechanism by which the two carabiners, one of which may be slightly larger than the other, are securely and reversibly interlocked together, thereby preventing the two carabiners from coming apart when the system is worn as a belt buckle. The small carabiner can be inserted into a center opening or hole in the larger carabiner so that the small carabiner can sit on top of the larger one. The two carabiners fit into each other by a narrowed neck at the base of the smaller carabiner so that the two carabiners interlock and fit anti-parallel to one another. The openings of the two carabiners are at opposite sides to each other when the two are interlocked providing fixed edges when combined. Thus, the two carabiners form one interlocked unit and serve to a function as a belt buckle when not in use as separate carabiners.

The two carabiners can reversibly interlock together with each other at one end of the larger carabiner via a lip that projects upwardly off the top inner edge of the larger carabiner. The two carabiners further interlock with each other at the other end of the larger carabiner via a pair of inwardly projecting protrusions or tabs from the bottom edge of the larger carabiner. The narrowed neck of the smaller carabiner rests between two inwardly projecting protrusions or tabs from the opening of the larger carabiner that allows both carabiners to sit securely against each other. The upwardly projecting raised lip portion on the inner edge of the larger carabiner and the pair of inwardly projecting protrusions or tabs from the bottom edge of the larger carabiner keeps the smaller carabiner in place and prevents it from detaching from the device. Only when the smaller carabiner is pushed away from the curvature of the lip and away from the two protrusions or tabs can it then be lifted away from the larger carabiner thus enabling the release of the smaller carabiner from the larger carabiner and the two come apart. The combination of the upwardly projecting raised lip and inwardly projecting protrusions or tabs on the larger carabiner work in concert with the smaller carabiner to achieve the desired interlocking mechanism. Tension on the waist belt or strap keeps the two carabiners joined and interlocked together, whereas release of the tension allows the user to release the two carabiners from their interlocked position.

A gate portion on each of the two carabiners, which can be opened or closed by pushing on an end of the arm that is not attached to the body of the carabiner, pivots the arm from the attached end. When the gate is in a closed the position, the gate extends between the top and the bottom of the carabiners.

The two carabiners also include base portion, which contains an attachment portion where the waist belt or carrying strap with the two ends can be secured onto the carabiners.

A variation of the base attachment portions allows different types of waist belt or straps to be attached to the two carabiners. Included in this application are 4 different variations of the attachment portion, for example, attachment portion having one, two, three, or four openings, and the like. The two circular-holed attachment portion and the four-holed attachment portion allow carrying straps made of circular climbing rope to be threaded. The two circular-holed attachment portion can sit perpendicular to the plane dimension of the carabiner at about a 30 degree to about a 45-degree angle to the base edge of the carabiner. The strap can be threaded at about a 90-degree angle to the plane of the carabiner allowing the strap to sit flat against the wearer of the belt. The two-holed attachment portion also can also be twisted at about a 45-degree angle against an axial plane of the carabiner, which prevents the rope from easily sliding and secures the length of the strap. The four circular-holed attachment design allows circular climbing ropes or bungee cords to be threaded through the 4 holes allowing secure attachment to the carabiners.

Another variation of the base attachment portion is the attachment with two rectangular slits, which allows a flat strap, more typical of belts to be attached to the carabiners and allows the length of the strap to be adjusted by the user.

Another variation of the base attachment portion is the attachment with one rectangular slit, which allows a flat strap of a fixed length to be attached to the carabiners.
