With reference to
As seen in
The belay tether 12 may be a conventional belay tether, such as a rope, strap or cable. Desirably, the belay tether 12 includes a loop or a ring 12a at the end thereof for interfacing with the belay tether connector 16. Typically, the belay tether 12 is associated with an automatic belay device 26, which connects to an elevated support 28.
The user tether 14 preferably has a length of from about 15 inches to about 50 inches to fit the majority of users. The user tether 14 may be made of any sufficiently strong tether material, but is preferably made of nylon strap material. An elastic member 14a is preferably connected to the user tether 14 to gather and compact the length of the user tether 14 when it is not tensioned, the compaction of the user tether 14 by the elastic member 14a facilitates storage of the tether 14 against the user U when the tip resistant system 10 is not connected to the belay tether 12, such as seen in
The belay tether connector 16 includes a removable connector 30 separable from the user tether 14, an integral connector 32 non-removably connected to the user tether 14, and a mechanical disconnect 34 operably associated with the removable connector 30 and the integral connector 32. Together, the integral connector 32 and the mechanical disconnect 34 as configured herein provide a desirable quick disconnect feature of the tip resistant system 10.
As described herein, integral connector 32 and the mechanical disconnect 34 of the belay tether connector 16 are configured to provide a quick disconnect feature that enables quick and easy connection to the belay tether 12 and also enables quick and easy disconnection from the belay tether 12. The quick disconnect feature is particularly desirable to enable the user U to quickly disconnect when using the invention in difficult conditions and environments. The quick disconnect feature enables the user U to disconnect from the belay tether 12 with limited engagement from the user, such as requiring the use of only one hand to accomplish disconnect.
With reference to
The integral connector 32 as shown in
The mechanical disconnect 34 includes a cord 60 operably associated with the cooperating rings 50 and 52, a lock member 62 fixedly coupled to the user tether 14 as by a band 62a, a handle 64 removably couplable to the lock member 62, and a relatively rigid cable 66 having one end fixed to the handle 64 and the opposite free end extending upwardly and positioned to be releasably connectable to the cord 60.
The cord 60 has a free end defining a loop 60a and an opposite end 60b affixed to the user tether 14. The loop 60a passes through an aperture 68 defined through the user tether 14. The handle 64 may be of molded plastic construction with the cable 66 being a nylon cord attached to the handle 64 during molding of the handle 64. As described more fully below, the loop 60a of the cord 60 is passed through the aperture 68 of the user tether 14. The cable 66 of the handle 64 extends through and past the loop 60a to prevent the loop 60a from passing back through the aperture 68. Once the handle 64 is pulled by the user to activate the quick disconnect feature, the cable 66 travels downward with the handle 64 to withdraw the cable 66 from the loop 60a.
In a preferred embodiment, the handle 64 includes a spring-loaded collar 70 and lock bearings shown in phantom as represented by reference numeral 70a (
The user connector 18 may be provided as by a locking carabiner or like structure. The user connector 18 may be connected to the user tether 14 as by a loop 74 sewn or otherwise formed on the user tether 14 (
The auxiliary tether 20 may be made of any sufficiently strong tether material, but is preferably made of nylon strap material. The auxiliary tether 20 has a length less than the length of the user tether 14, and preferably from about 5 inches to about 35 inches. Thus, the ratio of the length of the user tether to the length of the equipment tether preferably ranges from about 1.4 to about 3.0.
The user tether connector 22 may be provided as by a quick release carabiner or like structure. The user tether connector 22 may be connected to the user tether 14 as by a loop 76 formed on the user tether 14 adjacent the belay tether connector 16. In this regard, a loop 78 or the like receiving structure is desirably formed on the auxiliary tether 20.
The auxiliary user connector 24 may each be provided as by a quick release carabiner or like structure. The auxiliary user connector 24 may be connected to the auxiliary tether 20 as by a loop 80 formed on the auxiliary tether 20.
In the illustrated embodiment, the user tether 14 connects to the body harness 82 via the user connector 18, and the auxiliary tether 20 connects to the equipment 84, such as the strap of a backpack or other equipment, via auxiliary user connector 24. Absent the presence of auxiliary tether 20 connected between the user tether 14 and the equipment 84, the user U would not be able to maintain the upright attitude without the use of one or both hands and considerable effort.
