A double locking snap hook comprising a shank, a spring biased latch member and a spring biased locking means, the latch member and locking means being biased by two separate screens. One end of the shank defines a hook portion, and the latch member is biased toward a latched position for restraining straps, ropes, etc. within the hook portion. The locking means is biased toward a position which requires that the locking means be deactivated before the latch member may be unlatched or opened.
A continuously woven web includes a first woven region interwoven with a plurality of yarns to define a first weave pattern and a second woven region forming a continuous weave with the first woven region and having a continuation of the yarns. The yarns are attached to the second woven region at a distal end thereof. The second woven region has a length defined by a length between a first end positioned adjacent a termination of the first weave pattern and the distal end. In the second woven region, the yarns have a greater elasticity in aggregate and a shorter length than the second woven region. Upon application of a tensile force to the webbing, the yarns in the second woven region may elongate to a length limited by the length of the second woven region.
A safety hook that includes a body having a hook portion and a shank portion, a gate that is pivotally mounted from a gate pivot point on the shank portion, and a locking element that is pivotally supported from the shank. The safety hook also includes a peninsular portion that extends between the locking element and the and the heel portion of the gate, and a spring, the spring being mounted between and against the locking element and the locking element, so that to release the gate the user simply rotates the locking element away from the peninsular portion and then rotates the closure portion in, towards the mouth of the hook.
A double locking snap hook is provided with an extended hook shank and return portion to form a lengthened hook portion for use in conjunction with the assembly and disassembly of wall forms. A slot is provided in the hook shank through which may be inserted a strap made of webbing, leather or another sturdy, flexible material. This strap may in turn be connected to a worker's safety belt or harness, permitting the worker the use of both hands while securely attached to the wall form. In addition to other modifications, the return portion is narrowed somewhat to permit passage through the slots of the wall form bracing.
A joint member for use in an accessory comprises a linking section 11 and a receiving link section 12 being linked to this linking section 11, wherein the linking section 11 linked to a receiving link section 12 comprises a body 13, a C-shaped hooking portion 14 integrally provided on one end of the main body 13, a rotational opening/closing body 16 pivotally attached to the body 13, a spring 17 for imparting spring force in the direction separating the front terminus of the rotational opening/closing body 16 from the main body 13, a rotational limiting means for holding the front terminus of the rotational opening/closing body 16 at the closed position of an engaging/disengaging portion 15 and for limiting the rotation in the direction separating the front terminus of the rotational opening/closing body 16 from the main body 13, and the receiving link section 12 includes a receiving hook section 19 being hooked onto the C-shaped hooking portion 14.
An ergonomic snap hook that employs a recessed release to prevent undesirable unfastening. The snap hook uses a redundant locking gate that must be operated in a predetermined sequence to permit latch opening. Once the latch is opened, a rope or the like may be inserted into the hook to secure the user thereto. The snap hook is fastened to a supporting belt or strap which, in turn, is connectable, by the hook, to a body belt worn by the linemen. A spring biased, recessed gate prevents latch movement until the gate is released. Preferably, the gate mounts opposite of the latch. To unfasten the latch, the user first depresses the gate to align a follower on the latch with a slot opening on the gate. Subsequent follower movement along the slot coincides with latch release. The followers on the latch clean the slots on the gate as they move along them. The latch may then be opened by applying an appropriate pressure or force against the latch biasing spring. The gate may be easily manipulated with one hand. The body of the hook is shaped so that the user may easily position it in one hand. An ergonomic, thumb rest assists the user in manipulating the gate by providing a convenient pivot point for the thumb terminus.
