A carabiner includes a swivel loop and a body rotatably coupled to the swivel loop about a rotational axis. The body includes a spine having a spine axis that intersects the rotational axis at an intersection point disposed within the connection between the swivel loop and the body. The carabiner also includes a captive eye formed completely within the spine. The body and the captive eye being both rotatable relative to swivel loop.

An article for use with an associated vertically oriented, generally planar surface may include a generally horizontal top member supported by first and second planar supporting members, which selectively receive the associated vertically oriented, generally planar associated surface therebetween.

A method and fastening device for attaching polyester fiber panels to a substrate, such as a wall or a ceiling. The fastening device comprises an anchor part for attachment to the substrate and a fastening part for attachment to the panel. The fastening part comprises a cylindrical portion, a helical member surrounding the cylindrical portion for penetrating the panel upon rotation of the helical member and a recess in the cylindrical portion for receiving the anchor part. The thread angle of the leading edge of the helical member is greater than the thread angle of the trailing edge.

An outdoor appliance has a support frame with multiple inner lining tubes that are sequentially connected end to end by flexible ropes and multiple outer sleeve tubes that are slidable on the outer surfaces of the inner lining tubes. The outer sleeve tube and the inner lining tube at the head end of the support frame are respectively connected to an elastic member. When the support frame is in a locked state, each inner lining tube is located between and supports two abutting adjacent outer sleeve tubes. When the support frame is in an unlocked state, each inner lining tube is moved out of one outer sleeve tube and into the next successively axially adjacent outer sleeve tube against the force of the elastic member such that the radial support between adjacent outer sleeve tubes is eliminated thereby allowing the support frame to be folded.

A climbing instrument that comprises a first ring, a second ring that is larger than and engaged with the first ring. The second ring may comprise a gate that traverses a portion of the second ring and a rotatable cylinder that is positioned opposite the first ring and integrated within the second ring. The climbing instrument may also comprise a plurality of curved protrusions connected to and extending out and away from at least one of the first ring and the second ring.

A method for forming a stop flange on a self-tapping screw includes locating a shank of a self-tapping screw between two threading dies, fixing one of the two threading dies and moving the other one of the two threading dies to work the shank, the external thread forming section of each of the threading dies performing threading to form an external thread on the shank, inserting the insert and the recessed corner of each of the threading dies into a top of the external thread to form a groove in the shank, and the insert of each of the threading dies gradually squeezing downward an extruded portion that is formed during formation of the groove to form a stop flange on the shank. Thus, the shank is integrally formed with the stop flange, to stop an excessive movement of the external thread.

The present invention discloses a lock catch for pet traction, which comprises a traction hook and a pull ring connected with one end of the traction hook. The traction hook comprises a hook body, an even number of swinging resetting mechanisms and cylindrical pins. The hook body comprises a first connecting part and two installing parts; every two swinging resetting mechanisms form a group and are symmetrically penetrated in corresponding through holes; each swinging resetting mechanism comprises a swinging arm and a torsion spring; one end of each group of swinging arms positioned on the outer side of the installing part is positioned at a lower stopping point, and the other end can be mutually abutted against each other; and open ends limited by the two installing parts and the first connecting part are closed. The present invention has novel appearance, flexible and convenient use and difficult unhooking.

A safety harness connector assembly comprises a strap connector and an insert. The strap connector includes a base through which a base bore longitudinally extends and an extension. The base and the extension form an opening configured and arranged to receive a strap of a safety harness. The insert includes an intermediate portion interconnecting a first side and a second side, and the intermediate portion is configured and arranged to be received within the base bore. The first side includes a protrusion and the second side includes a shoulder portion. The protrusion and the shoulder portion are configured and arranged to engage opposing ends of the base when the intermediate portion is received within the base bore to secure the insert within the base.
