A tether fastening device includes a tether clip and a strap to couple a first engagement structure, such as a vehicle chassis, and a second engagement structure, such as a body panel. The strap is coupled to the tether clip and couples the first engagement structure with the second engagement structure to allow for controlled detachment. When attached, the tether clip fastens the first engagement structure with the second engagement structure. For example, the tether clip and first engagement structure may detach from the second engagement structure; however, the strap controls the acceleration, speed and distance displaced between the first engagement structure and the second engagement structure. According to one embodiment, the tether clip may further include a tether cap integrated with the strap and a fastener clip operative to couple to the tether cap.

A fastener clip includes a base plate and a pair of laterally offset arms extending from the base plate. The fastener clip is operative for insertion into a hole (slot) defined in a first engagement structure, such as a vehicle chassis. At least four wings extend from the arms. Each wing includes at least one engagement portion including a depressed portion formed on each wing, wherein each depressed portion is operative to engage a portion of the hole. According to one embodiment, each arm is coupled to at least one wing at a distal end of each arm (i.e., a long arm), so that each wing extends inwardly towards the base plate. According to an alternative embodiment, each arm (i.e., a short arm) is coupled to the at least one wing, so that each wing extends outwardly away from the base plate.

This invention relates to a spring fastener, which comprises engagement springs in opposite sides of the fastener. Each engagement spring has an engagement region comprising a hindrance portion, which increases considerably the removal to insertion force ratio as compared to such ratio in the absence of the hindrance portion, thus permitting very easy insertion with considerably more difficult removal of the fastener from the slot of a panel, which provides an efficient ergonomically balanced removal to insertion force ratio. The hindrance portion comprises ripples or other hindrance elements of unexpectedly minute dimensions for providing this efficient ergonomic force balance. The combination of the above structures with the presence of barbs being bent at their front portion improves immensely the ergonomic character of the devices.

An anchor facilitates blind engagement by a first fastener in order to connect an object to a wall. The anchor may be inserted into a cavity accessible through a hole defined in a hollow substrate to connect the object to the wall. The anchor includes a base plate and a pair of laterally offset arms extending from the base plate, such that each arm includes an engagement structure disposed at a distal end of each arm. The engagement structure of each arm cooperatively supports the anchor and complementarily engages the first fastener. The first fastener may be a bolt, a screw, or any suitable fastener such as a threaded fastener. The engagement structure includes a collar extending outwardly from each arm for engaging the hollow substrate upon insertion of the anchor into the cavity. Additionally, the engagement structure includes a tang extending inwardly from each arm, generally defining a portion of a first aperture for engaging the first fastener.

A magnetic fastener clip includes a base and an umbrella positioned on the base. A boss is attached to the umbrella and extends outwardly from the umbrella and away from the base. The magnetic fastener has a hole with a diameter to receive the boss. The boss is welded to hold the magnetic fastener against the umbrella. An optional carrier is attached to the base to provide additional height for suitable applications. The umbrella is positioned on the base or is attached to the carrier and positioned opposite the base. The boss is attached to the magnetic fastener such that the umbrella flexes to permit the magnetic fastener to pivot about the boss. The magnetic fastener clip adapts to different surface curvatures and thicknesses. The magnetic fastener clip is operative for blind attachment into a structure, such as a vehicle chassis i.e. roof.
摘要:
A spring fastener characterized by a structure having a cavity in which the rib of a first part, such as a plastic panel for example, like a pillar, may be engaged, and is also suitable to be engaged reversibly in a slot of second part, such as a metal sheet for example, like the frame of a car. The spring fastener comprises engagement springs having a peak, engagement regions and-side cuts in the vicinity of the peak, preferably within the engagement regions. The side-cuts, of preferably triangular shape, increase considerably the lever/angle pulling force (pulling force applied on the first part and away from the spring fastener, in order to separate the first part from a second part connected together with the spring fastener). It is highly preferable that the fastener comprises barbs with inwardly bent front ends, and that the engagement regions further have hindrance portions, the combination of which highly improves the balance of insertion to removal ratio.
