Patent number: 8850673Abstract: Use of a snap hook requires the capture loop to be cradled in a joint of the index finger to prevent it from rolling in the hand. Hooks having a cylindrical body roll easily, and those having an oval section capture loop, roll more easily. When a hook rolls, its loop can move to a position where it blocks access to the gap, requiring it to be repositioned in the hand. Ergonomic requirements provided in this hook include: spacing the hand a maximal distance from the gap, stability from rolling in the hand, and minimal movement of the hand members in operation. The hand does not close around the hook; it may be held between the thumb and a finger, a natural configuration in which the hand retains the lie of its usual open form. Stability from rolling results from the forces of contact being directed within the borders of the wide contact surfaces of the body and the button. The larger the contact forces, the more stable the hook is.Type: GrantFiled: October 6, 2010Date of Patent: October 7, 2014Inventors: William Harold Carveth, William Vincent Carveth

-
Patent number: 8621728Abstract: A locking carabiner having an eccentric pivot that when rotated causes a reciprocating motion that moves the opening end of the gate into or out of locking engagement with the carabiner body. Rotation of the eccentric is controlled by a short lever that can be easily moved by a fingertip, consequently the gate can be conveniently manipulated and locked with the fingers of one hand. The locking mechanism adds negligible weight and bulk to the carabiner. The locking mechanism can be incorporated on bent gate, straight gate and wire gate carabiners.Type: GrantFiled: August 8, 2012Date of Patent: January 7, 2014Inventor: Tony Christianson

Patent number: 8544155Abstract: A safety hook includes a main body defining an inner space and an opening, a latch unit pivoted to the main body, an operable unit pivoted to the main body, and a safety lock unit. The latch unit is normally at a closed position for blocking the opening. When the operable unit is pressed, the safety lock unit is co-rotatable with the operable unit with respect to the main body from a locked position, where the safety lock unit abuts against the latch unit to retain the latch unit at the closed position, to an unlocked position, where the safety lock unit is removed from the latch unit to allow the latch unit to rotate from the closed position to an opened position allowing access into the inner space through the opening.Type: GrantFiled: December 19, 2012Date of Patent: October 1, 2013Assignee: Usang Industrial Co., Ltd.Inventor: Yu-Wen Lin

Patent number: 7992267Abstract: A locking mechanism is contained within a carabiner's straight or bent gate. The locking mechanism incorporates a pivoting link that can be moved to abut against a transverse pin, thereby immobilizing the gate return spring, which prevents opening movement of the gate. The transverse pin is a material able to resist and distribute forces attempting to open the locked gate. The spring pin is notched to engage the transverse pin thereby simplifying assembly of the carabiner. A low profile protrusion is pushed in the direction of opening the gate to switch the mechanism to the unlocked position. Similarly, another low profile protrusion is pushed in the direction of closing the gate to switch the mechanism to the locked position. The locking and unlocking protrusions are located adjacent the gate hinge so that the gate can be conveniently unlocked, opened, closed and relocked with the fingers of one hand.Type: GrantFiled: June 26, 2007Date of Patent: August 9, 2011Inventor: Tony Christianson

Patent number: 7810220Abstract: A coupling device for engagement with an anchor member is provided. The coupling device includes a lever that moves between a closed position that substantially covers the mouth of the device and an open position in which the mouth is substantially uncovered by the lever. The lever may be moved to the open position by camming forces or by direct manipulation of a portion of the lever by a user. The coupling device may include a cover with a recognizable shape such as a pet or fictional character. The protruding ears and/or head of the recognizable shape aid in the gripping and operation of the device and the mouth receives the anchor member.Type: GrantFiled: April 16, 2004Date of Patent: October 12, 2010Assignee: Indiana Mills & Manufacturing Inc.Inventors: James R. Anthony, Guy R. Dingman

Patent number: 7757360Abstract: A safety hook includes a hook body, a pivotable safety retainer biased to a locking position, and a pivotable latch member biased to abut against a distal end of a hook portion of the hook body to thereby close a hook mouth defined by the hook body. The safety retainer includes a stop portion and an abutment face unit. When the safety retainer is disposed in the locking position, the stop portion abuts against the latch member, and the abutment face unit is adjacent to and spaced apart from a stop block of the hook body. In the locking position, if an external force is applied to pivot the latch member away from the distal end of the hook portion, the abutment face unit will come into contact with the stop block to prevent further pivoting movement of the latch member.Type: GrantFiled: March 5, 2009Date of Patent: July 20, 2010Inventor: Rong-Der Hong

Patent number: 6941622Abstract: A hook is capable of hooking a chain at a desired length. The hook comprises a hook body, and a buckle above the hook body. The buckle has a U shape opening. Width of the shape opening is confined by the size of a chain to be hung. The buckle, has a penetrating groove which penetrates two inner sides of the buckle and one outer side of the buckle. A spring and a movable shaft pass through the penetrating groove. The movable shaft is positioned by a pin so that the spring is compressed by the movable shaft and the movable shaft will not drop out of the buckle. A notch is formed at a predetermined portion of the movable shaft. A semi-round groove is formed at a coupling portion of the buckle and the notch, and the semi-round groove is positioned across the two inner sides of the buckle.Type: GrantFiled: April 21, 2003Date of Patent: September 13, 2005Inventor: Rung Te Hung

Publication number: 20030097737Abstract: Disclosed is a static line snap comprising an elongated body having front and rear portions separated by an attachment portion. The attachment portion defines an attachment cavity with a lock end. A slot is defined by the front portion for entry to and exit from the cavity. An outer gate is mounted to the body front portion for pivotal movement between a lock position and a load position. An inner gate is mounted to the body rear portion for pivotal movement between a lock position and a load position. Pivotal movement of the outer gate toward the load position forces the inner gate toward the load position. Each gate is independently biased toward the lock position.Type: ApplicationFiled: November 27, 2001Publication date: May 29, 2003Inventor: Yakov Gartsbeyn
