Abstract: A compact device for absorbing kinetic energy generated by, for example, broken electric power lines on electric power transmission towers. The device consists of a non-spring helix, or in or out of plane flat coils that are placed between an electric transmission tower and the conductor insulator. The device deforms by plastically uncoiling in response to forces greater than a predetermined force. The device is a single-event device, designed to be replaced after one extraordinary dynamic event. The device can also be used in other structures or machinery requiring compact long stroke energy absorption.

Abstract: An energy absorbing device used as a load limiting member in a structure to control its response to applied loads is disclosed and functions by utilizing a spool assembly 20 having flanged ends 36 and an interior cavity 34 of sufficiently large diameter to cause it to deform plastically at a prescribed load. In application, the spool 20 is utilized as a pivot point for the legs 14 of an aircraft seat 12. When properly designed and integrated into the seat arrangement 10, the spool 20 will twist about its axis, deforming plastically when the impact load exceeds the spool yield value. Through this deformation, spool 20 absorbs the kinetic energy of the movement of seat 10 at a substantially constant rate, thereby controlling the level of loads transmitted to the seat occupant. By proper sizing and selection of materials, it is possible to control load response in a predictable manner.

Abstract: A collapsible barricade comprising a rigid cross-member coupled by an elastic joint to at least one pair of rigid legs. The elastic joint is developed by a flexible, elastic, resilient connecting member which is attached at one end to the cross-member and at the other end to the rigid leg in a manner such that the formed elastic joint is capable of stretching under stress to allow the pair of legs and attached cross-member to deform from a sturdy configuration when subjected to an impact by a vehicle or other moving object. The collapsible barricade can then be restored to its sturdy condition by merely repositioning or reattaching the connecting members to the respective legs and cross-member and by repositioning the deformed structure to its original configuration.

Abstract: This invention relates to a block member adapted to secure a cable or wire to a support surface. The block member has a pair of cylindroconical bores with each being adapted to receive a pointed pin therethrough. Each pin has a frustoconical end with an included angle which is less than the included angle of the frustoconical portion of the cylindroconical bore. Around the open end of each bore is an impact absorbing ring. The ring is of the same material as the block member and is adapted to substantially absorb the excess energy that the tool used to drive the pins may contain by crushing on impact. The block member has each bore disposed within a freely depending sleeve to permit the axis of the pin and bore to shift, to a point where the axes could move to thereby permit the pointed end of the pin to avoid a substantially impenetrable object.

Abstract: Belt clip assembly for use with a portable electronic apparatus includes a mounting bracket used to join a belt clip and a housing member. A mounting bracket is inserted through a pair of slots in a housing member and holds a belt clip in place by means of a pivot pin inserted through apertures in the mounting bracket and the belt clip. A pair of shear cuts adjacent the apertures in the mounting bracket allow the pivot pin to pull through the shear cuts in the event excess forces are applied to the belt clip, thereby destroying the mounting bracket. In this manner an inexpensive mounting bracket is sacrificed to avoid damage to the housing and the belt clip.

Abstract: A prop made from an elongate timber element. The cross-sectional area of the element is reduced in at least one region e.g. by tapering the element, forming circumferential grooves in it, or boring holes axially or transversely into or through the element. The region of reduced cross-section is reinforced by means of bands or a sleeve which extends circumferentially around at least part of the region. The reduced cross-sectional area promotes deformation of the prop and the reinforcement controls the rate of deformation.

The impact fractures one of the shear pins and the second member rotates about the pivot pin away from the impact. Single post and multiple post support structures are disclosed. A support structure having two vertical members collapses to a flattened position when struck from any direction. The vehicle passes over the flattened support structure. In an alternate embodiment, the support structure rotates upward upon impact and passes over the vehicle.

Abstract: A notched-energy absorber for attenuating high level accelerations such as ould occur during aircraft crashes, thereby avoiding injury to a user. The energy absorber force-displacement curve has a large initial spike, followed by a valley or "notch" and then by a constant force level intermediate the spike and valley levels. In one embodiment, a conventional square-response type shock absorber is connected between a vehicle seat and the vehicle body by a shearable diaphragm fixed to vehicle structure. The diaphragm shears at a notch when it experiences an initial high force, after which the conventional absorber moves freely without deforming until it encounters a stop. The conventional absorber then elongates or compresses in a conventional manner. In an alternative embodiment, a spring is connected between the seat and the vehicle body. Initially, the spring is compressed by experienced forces until at a predetermined force level it forces out a retaining clip or ring.
