Reconnectable breakaway rope safety connector

Abstract
A re-attachable breakaway safety connector is disclosed which is adapted for use with a rope or other objects arranged in at least a substantially linear manner such that when force is provided to the objects, a tensile force is transferred to the connector. The breakaway connector is designed to fail, i.e., the components separate, when the tensile force transferred to the connector exceeds a predetermined level, and may be selectively adjusted to reduce the amount of force required to separate a male and female component of the safety connector.
Description




FIELD OF THE INVENTION




The present invention relates generally to breakaway safety fasteners. More specifically, the present invention relates to breakaway safety fasteners used in association with boundary markers and even more particularly, to re-attachable breakaway connectors for boundary markers along snow skiing trails.




BACKGROUND OF THE INVENTION




At snow skiing resorts, groomed ski trails or “runs” are provided on the face of a mountain or hill to provide routes for skiers to descend from the top of the resort to the bottom. Many of these trails have defined boundaries. The out-of-bounds areas are often too dangerous due to the steep incline or extreme risk of avalanche danger. Further, some of these areas may be outside the ski area's United States Forest Service (U.S.F.S.) permit area. Thus dangers in the out-of-bounds areas may be created by dense timber, steep inclines, insecure foundation for the snow beds causing avalanche concerns, insufficient snow cover, or other hazardous conditions.




In order to prevent skiers from accessing these areas, the defined boundaries are often marked by ropes, fences, or panel sheets fastened to stakes or other secure items, e.g., trees, 4×4's, or other stanchions along the boundary line. The ropes or fences not only mark the boundary, but also provide a visual and limited physical barrier to skiers attempting to travel into the out-of-bounds or closed areas.




Unfortunately, the rigidity of the ropes or fences can cause an abrupt change of velocity of the skier. Thus, skiers may be injured when striking the rope or fence while skiing or snowboarding. The force at which a skier strikes the boundary marker may cause broken bones, severe bruising or even internal injuries or death. Additionally, the abrupt change of velocity may cause injury to the head or neck of the restrained skier. Although generally designed for the skiing industry, it should be appreciated by one skilled in the art that the present invention may be used in any type of setting or industry where a boundary is identified and the potential for any person hitting the boundary at an increased velocity is present.




Thus, a significant need exists for a boundary or closed marker connection system which will provide a visual and limited physical barrier, yet minimize the injuries caused to the skier when encountering the boundary marker or rope closure at a potentially high velocity. The boundary marker connection system or rope closure should be capable of failing at a predetermined level necessary to prevent these injuries, yet providing a necessary resistance to prevent becoming detached or collapsing merely when a skier, snowboarder, or patron brushes it or during high wind conditions. Additionally, it would be desirable to provide a connection system that is capable of failing at a predetermined level but that may be reconnected in a simple and efficient manner. In this way, replacing the boundary marker takes minimal time and has minimal cost. By minimizing the time to replace the boundary, other skiers may be prevented from traveling off of the defined ski trail. Also, the cost of replacing the boundary marker prevents unnecessary cost to the operator of the ski resort.




SUMMARY OF THE INVENTION




It is thus one aspect of the present invention to provide a breakaway safety connector for use with boundary markers and rope closures which addresses the limitations of products currently known in the art by being capable of failing at a predetermined tension level. This aspect may allow for the prevention of serious injury to persons running into the boundary marker or rope closure.




It is another aspect of the present invention to provide a breakaway safety connector for use with boundary markers or rope closures which is capable of being reconnected after failure, and which can thus be used repeatedly. In this way, the boundary marker or rope closure may be replaced with minimal effort and time, thereby providing others with a clear indication of boundary lines.




In yet another aspect of the invention, the device is made of a material which allows a portion of the male end to be reduced in size, and thereby reducing the tensile strength of the connector. This provides the user with a method of selecting the tensile strength desired in the connector by reducing the diameter of the connector along at the male end, thus providing a breakaway connector which can be custom designed for a variety of applications. Alternatively, it is another aspect of the present invention that the female component of the connecting end may be selectively increased in size to reduce the amount of tensile force required to separate the male component and female component.




It is yet another object of the present invention to provide a breakaway safety connector which is not reusable and shatters or breaks during failure when a predetermined amount of force is applied. In all embodiments, a light weight, generally inexpensive apparatus is provided which can substantially reduce the risk of injury or death to someone hitting a rope or other barrier device.




Additional advantages of the present invention will become readily apparent from the following discussion, particularly when taken together with the accompanying drawings.

DETAILED DESCRIPTION




The present invention, including the preferred embodiments, may be seen in

FIGS. 1-12

, which show a re-attachable breakaway safety connector specifically designed for attachment to a boundary marker or rope closure. The re-attachable breakaway safety connector in one embodiment is generally comprised of two components. Each component has an attachment end for attachment to a boundary marker such as a rope, cable, chain or webbing or any other type of material known in the art which may be used as a boundary material or closure. The two connectors are also capable of being releasably interconnected to one another and, if separated, selectively reconnected.




With reference to

FIG. 1

, a female component of the present invention is shown. The female component


10


is comprised of a female component body


12


with an attachment end


14


and a female connector end


16


. The attachment end


14


is designed to be connected to a rope or other boundary marker. Thus, the attachment end


14


includes an attachment aperture


18


. A rope may be tied or looped to the attachment end


14


of the female component


12


by inserting an end of the rope through the attachment aperture


18


and knotting or looping the rope about the attachment end


14


or the rope itself.




As shown in

FIG. 1

, the attachment end


14


may also include a passage


20


for receiving the rope, clip or other attachment mechanism. With this feature, a looped end of rope may be attached to the attachment end


14


by sliding the looped end of rope through the passage


20


into the attachment aperture


18


. The passage


20


also may accommodate attachment to a chain or other object that cannot be tied to the attachment end


14


.




The female connector end


16


of the female body


12


is designed to be connected to the male component, as described below. The female connector end


16


includes a connector socket


22


. A connector slot


24


may additionally be provided between an external surface of the female connector end


14


and the connector socket


22


.




The female component body


12


may also include a reinforcing ridge


26


along at least a portion of the female component body


12


. The reinforcing ridge


26


is a raised portion of the female component body


12


used to provide increased structural integrity to the female component body


12


. As shown in

FIG. 1

, the reinforcing ridge may also extend around at least a portion of the attachment aperture


18


to provide enhanced structural integrity and also to increase the bearing surface of the attachment aperture


18


.




Referring now to

FIG. 2

, the female component


10


of

FIG. 1

is shown in a top plan view. In this embodiment, the female connector end


16


is formed by a first connector arm


28


and a second connector arm


30


. The first and second connector arms


28


and


30


define a channel


32


in the female connector end


16


. The channel


32


is designed to receive the body of the male component as described below.

FIG. 3

shows a right end elevation view of the female component


10


as seen from the female connector end


16


.

FIG. 4

depicts the female component


10


in an upper perspective view, and which again identifies the first connector arm


28


, second connector arm


30


and other components.




Referring now to

FIG. 5

, one embodiment of a male component of the present invention is shown. The male component


34


is generally comprised of a male component body


36


having a attachment end


14


and a male connector end


38


. The attachment end


14


of the male component


34


of this embodiment is generally identical to the attachment end


14


of the female component


10


as described above, and is thus adapted to receive a rope or other type of barrier device.




The male connector end


38


of the male component


34


includes a connector post


40


. The connector post


40


is sized to be received into the connector socket


22


of the female component


10


. The connector post


40


is a projected area at the male connector end


38


of the male component


34


. As shown in

FIG. 5

, the connector post


40


may be a cylindrical wall with a hollow center. It is understood, however, that a connector post


40


may be comprised of a solid cylinder or other solid or walled geometries. It should also be understood that the connector socket


22


of the female component


10


should have a substantially corresponding and mating geometry, and the two are designed to be engaged with such a high degree of tolerance that it takes a predetermined force to disengage the two components. Thus, high wind, drifting snow and other similar events will not prematurely disengage the connector. As in the female component


10


above, the male component body


36


may include a reinforcing ridge


26


along at least a portion of the male component body


36


. Additionally, the reinforcing ridge may also be formed adjacent to the attachment aperture


18


for providing structural rigidity as well as increased bearing surface of the attachment aperture


18


. As further appreciated by one skilled in the art, the geometry of the male and female connectors are not critical as long as the two components matingly engage and can be selectively disconnected. Thus these components may be round, oval, peg-shaped, triangular semispherical or any other shape which conceivably can be fit together with male and female components.




Referring now to

FIG. 6

, the male component


34


of

FIG. 5

is shown in a top plan view. In this embodiment, the connector post


40


is shown extending outwardly from both sides of the male component body


36


. It should be understood, however, that other embodiments of the connector post


40


are possible. For example, the connector post may extend from only one side of the male connector body


36


, as opposed to both sides. Preferably the connector posts


40


are comprised of a plastic, wood, rubber or other material which can be selectively reduced in size with an abrasive material such as sandpaper or rasping tools to effectively reduce the diameter and selectively reduce the amount of force required to detach the male component


40


from the female connector slot


24


.




With reference to

FIG. 7A

, the male component


34


is shown in a right end elevation view as viewed from the male connector end


38


. Similarly,

FIG. 7B

shows a cross section of the male component


34


as seen from cross section A—A as indicated in FIG.


5


. With reference to

FIG. 8

, the male component


34


is shown in a front perspective view.




Referring now to

FIG. 9

, one embodiment of the breakaway connector


42


of the present invention is shown with the corresponding male and female connections releasably interconnected. The breakaway connector


42


is the combination of a female component


10


and a male component


34


of the present invention as described above. The portion of the male component body


36


adjacent to the connecting post


40


is inserted into the connector slot


24


of the female component


10


such that the connecting post


40


is seated within the attachment aperture


18


. Once property inserted, the connection of the female component


10


and the male component


34


require a predetermined tension level to be separated again. As shown in

FIG. 9

, the reinforcing ridge


26


of the male component


34


may be abbreviated such that the male connector end


38


may be rotated within the female connector end


16


such that the reinforcing ridge


26


does not interfere with the female connector end


16


.




The breakaway connector


42


, and all components and pieces thereof, may be formed of substantially any material. It is desirable, however, that the material used for the connector


42


have some resilience and elasticity such that when the necessary tensile force is applied, the first and second connector arms


28


and


30


expand to allow disconnection with the connector post


40


without structural damage. Some such materials may include, but are not limited to rubber, nylon, polyvinyl chloride, polypropylene, polypropylene, polyethylene, or other plastics known in the art. Alternatively, certain metallic materials such as stainless steel may be suitable for this purpose.




Additionally, the size and shape of the breakaway connector


42


may vary. Thus it is possible to design a breakaway connector


42


with virtually any required tensile strength for failure. However, it is anticipated that the breakaway connector


42


and its component parts should be designed to require a tensile strength of between about 30 and about 50 pounds (lbs), and more preferably about 40 lbs, prior to disengaging the male component


34


from the female component


10


.




Referring now to

FIG. 10

, a preferred embodiment of the female connector end


16


is shown. In this embodiment marks


44


are provided on the female connector end


16


to indicate the tension strength of the connection between the female component


10


and the male component


34


if the connector slot is extended to corresponding marks


44


. A user may trim the female connector end


16


by removing that portion of the female connector end up to and including the mark


44


. In this way, the user may select the proper tension level for a given application. Alternatively, the male connecting posts


40


may be selectively reduced in diameter to reduce the force required to separate the male and female components of the breakaway connector


42


. As shown in

FIG. 11

, the marks may have corresponding grooves


46


such that the user may properly locate a cutting utensil along the mark


44


. The grooves


46


simplify the trimming process.




Referring now to

FIG. 12

, a depiction of the present breakaway connector


42


in use is provided herein. As shown, the breakaway connector


42


is typically interconnected to a rope


48


or other barrier device, which is in turn positioned between two substantially non-movable objects such as trees, rock outcroppings, stanchions


50


, or other similar devices or objects.




While various embodiments of the present invention have been described in detail, it is apparent that modifications and adaptations of those embodiments will occur to those skilled in the art. However, it is to be expressly understood that such modifications and adaptations are within the scope and spirit of the present invention, as set forth in the following claims.
