Abstract: A Simple Climber's Multi-Tool which performs multiple safety functions for the field of rock climbing. The device is a convenient effective safety back-up device to be used with a solo lead climbing belay device. The device also functions as a standard belay and rappel device. With the addition of an Attachment Snap Hook, the device is an auto-locking belay device for one or two ropes. With the addition of a loop of cord, it can perform functions otherwise performed with specialty knots for safety and self-rescue such as the Prusik knot, Bachman knot, and Klemheist knot. The device can be easily moved along the rope when the First Snap Hook is gripped and pulled with respect to either end of the rope, but will jam the rope against movement when the Main Body of the device is constrained from movement and an end of the rope is pulled with respect to the device.

Abstract: A Self-Belay And Rappel Device (10) is presented which will arrest the fall of a climber who is solo lead climbing, and will also allow the climber to rappel down a Rope (36). The simple and inexpensive device comprises a Left Side Face (12), a Right Side Face (14), Cylindrical Stand-Offs (16) which separate and join to the two side faces, and a Brake Surface (18) extending between the two side faces. In use for fall arrest, the device is attached, using two karabiners, both to a climber's chest harness and to the climber's waist harness. A third karabiner is clipped through two slots in the device, one slot in each of the two side faces. The fall of a climber causes the third karabiner to be pulled up within the two slots, ultimately locking the device against the climber's Rope (36) by causing the Rope (36) to become pinched between a portion of the third karabiner and the Braking Surface (18).

Abstract: A simple, economical, and highly effective auto locking belay device is presented, certain embodiments of which contain no moving parts. The simplicity of the device is due to the fact that it derives certain functionality from its attachment carabiner that would normally be found within an auto-locking belay device itself. In its simplest form, the Device (10) comprises only a Body (14) with an Inner Channel (16) and a Pin (12). The attachment carabiner supports the path of the rope through the device, constrains an axis of rotation around which the device rotates, and provides one of two surfaces between which the rope is pinched. The device is able to extract these functions from the carabiner due to a unique, and counter-intuitive, placement of the carabiner within the same geometric plane as the path of the rope through the device.

Abstract: A Simple Climber's Multi-Tool (10) is presented which performs multiple safety functions for the field of rock climbing. Most importantly, the device fulfills a heretofore unmet need for a convenient effective safety back-up device to be used with a solo lead climbing belay device. The Simple Climber's Multi-Tool (10) also functions as a standard belay and rappel device. With the addition of an Attachment Snap Hook (52), the device is an auto-locking belay device for one or two ropes. With the addition of a loop of cord, it can perform functions otherwise performed with specialty knots for safety and self-rescue such as the Prusik knot, Bachman knot, and Klemheist knot. The device comprises a Main Body (12) to which is attached a Snap Hook Containment Loop (20), and a First Snap Hook (24). A Rope Channel (18) runs through the device. A unique shape of the Back Face (15) of the device is of primary importance to its rope jamming capability.

Abstract: A Locking Device To Prevent Door Removal (10) is provided to prevent theft of a type of door having a hinge pin fixedly attached to the door and a hinge bracket bolted to the door frame housing with bolt holes extending into the door frame housing. The device replaces one of the standard bolts, used to secure the hinge bracket, with an Elongated Bolt (12). A Blocking Piece (20) with a Blocking Piece Through-Hole (38) is positioned over the Elongated Bolt (12) and locked in place with a Padlock (42). The Shackle (40) of the Padlock (42) extends through a Bolt Through-Hole (18) in the Elongated Bolt (12). The Blocking Piece (20) blocks the hinge pin from being lifted out of the hinge sleeve. The Padlock (42) both holds the Blocking Piece (20) against movement and prevents the Elongated Bolt (12) from being removed.

Abstract: An improved Belay Device is provided consisting of a Base (14), Rope Locking Ring (36), Cover (48), and Connecting Pin (58). The Base (14) contains a Protruding Cylindrical Core (18) with a Base Rope Channel (20). The Protruding Cylindrical Core (18) is received within a Central Hole (34) of the Rope Locking Ring (36). The Rope Locking Ring (36) contains an Upper Ring Rope Channel (38) and Lower Ring Rope Channel (40) that, in normal operating configuration, align with the Base Rope Channel (20) thus forming one continuous rope channel. An abrupt force on a rope passing through the device causes the Rope Locking Ring (36) to rotate with respect to the Protruding Cylindrical Core (18) thus destroying the alignment of the Lower Ring Rope Channel (40), Base Rope Channel (20), and Upper Ring Rope Channel (38). The rope thus becomes pinched or locked in the transition regions between these rope channels.

Abstract: A Safe Auto-Locking Belay Override Mechanism (24) is provided which causes an auto-locking belay device to lock a rope against movement if a belayer panics, as sometimes happens if a climber falls, after the belayer has overridden the normal function of the auto-locking belay device. The mechanism of the subject invention makes use of the realization that a belayer tends to grip an auto-locking belay device tightly when the belayer panics. The subject invention contains a pressure sensitive activation mechanism that acts on an override mechanism such that the normal function of the belay device will be overridden by only one of three different force levels. At either relatively low or relatively high levels of force exerted by the belayer on the pressure sensitive activation mechanism, the auto-locking belay device will function normally and lock a rope against further movement in the event that the rope exerts sufficient force on the auto-locking belay device such as when a climber falls.

Abstract: A door handle lock (20) for hinged lever-style door handles (10) adapted for mounting on a portion of a hinged lever-style door handle (10) and overlapping a portion of a door handle housing (12), the door handle housing (12), with a hinged lever-style door handle (10), is received in a portion of a door, the hinged lever-style door handle (10) used for opening the door. With the door handle lock (20) in place on the hinged lever-style door handle (10), the door cannot be opened because the handle cannot be moved. Attempts to move the door handle (10) are unsuccessful because the door handle lock (20) interferes with the door handle housing (12) if one attempts to move the handle (10), thus preventing movement thereof.
