Abstract: A manually installed fastener includes a fastener body having parallel first and second plates, the second plate having an aperture. A bend member integrally joins the first and second plates. The bend member has an outer deflectable leg integrally connected to the first plate and an inner deflectable leg integrally connected to the second plate. A first barb is integrally connected to the first plate and extends through the aperture of the second plate. A second barb is integrally connected to the second plate and is oppositely oriented with respect to the first barb. The second barb and the second plate are elastically displaced with respect to the first barb and the first plate to change a clearance diameter between the first and second barbs.

Abstract: The device essentially consists of a substantially rigid piece that has a first portion (1), a second portion (2) and conventional means (3) for securing the piece onto a fastening surface (6). The first portion (1) forms a space such that once the head (5) of the coupling element (4) is introduced inside the space, the rotation of the coupling element (4) around its own axis is prevented (anti-rotation function). The second portion (2) is connected to the first portion (1) in a part of the second portion located opposite to the opening of the space through which the head (5) of the coupling element (4) is introduced. In such a way that once the piece is mounted on the head of the coupling element, the axial movement of the coupling element (4) is prevented (retention function).

Abstract: A resilient clip is disclosed for engaging a structure having a body with a pair of extending body portions and an elastic flange. The flange has an engagement surface and an engagement member, which engages the mounting structure. The elastic flange also has a base portion and a transition portion. A ramped surface of the engagement feature extends above the base portion. A substantially flat peripheral surface of the engagement feature in the transition portion is adapted to engage the panel to provide resistance to removal of the fastener from the mounting aperture. To manufacture a clip, a punch is used to apply a force to displace material of the elastic flange into a die cavity to form the engagement. The elastic flange portion is bent at a location passing through the engagement feature.

Abstract: A power steering apparatus (10) includes a conduit (50) through which a flow of power steering fluid is conducted and a housing (22) having a chamber (25) which holds power steering fluid. A connector assembly (60) connects the conduit (50) with the housing (22). The connector assembly (60) includes a base (64) which is fixedly connected with the housing (22) and a clip (66) which interconnects the base and the conduit (50). The clip (66) has a pilot portion (76) with cam surfaces (88 and 90) which engage a projection (68) on the conduit (50) to press the conduit into an opening (78) in the base (64) during connection of the conduit with the base. The clip (66) has a retainer portion (74) which cooperates with the base (64) and the projection (68) on the conduit (50) to compress a seal (70) between the projection on the conduit and the base when the conduit is connected with the housing (22).

Abstract: In a toothed-rack power-assisted steering, which is provided for motor vehicles in particular, a pinion (2) seated in a steering housing (1) is in engagement with a toothed rack (6). A servo motor (8) is disposed as a power assist, whose piston rod (10) is drivingly connected with the toothed rack (6). The two work chambers (12, 13) of the servo motor (8) are connected with a control device (18) via work lines (12, 13), which are connected with a cylinder (11) of the servo motor (8) and with the control device (18) via two connecting elements (24, 25). Each work line (14, 15) has a collar (32). Each line is held on the connecting element (24, 25) by a fastening clasp (34) which projects over the collar (32). The fastening clasp (34) has an essentially rectangular and flat base (35). An elongated slit (36), open toward one side, is located in the base (35), through which the fastening clasp (34) can be pushed from the side over the line (14, 15) and the connecting element (24, 25).

Abstract: An improved U-nut with the ability to be frictionally mounted to a panel by the frictional engagement of first and third legs with the panel. The third leg is resiliently connected to a second leg that is in turn connected to the first leg. A threaded barrel on the third leg receives a fastener to connect two panels together.

Abstract: Preferred embodiments (60, 70) of a fastener adapted to secure any selected one of a plurality of threaded members (S") are provided. Fastener (60) features substantially parallel spaced-apart flat plate members (2, 4) preferably folded from one piece to provide a resilient end fold (6) connecting them together at one end and which features respective apertures (28, 26) that are axially offset by a distance ("x") and have respective thread engaging edges (24, 20) about at least a portion of their respective peripheries that are oriented to cause at least one of plates (2, 4) to rotate relative the other a distance effective to enable apertures (28, 26) to align sufficiently to enable threaded members ("S") to advance rotationally therethrough with end fold (6) further adapted to impart a resistive force against the threads that is effective to enhance the secured relationship therebetween.

Abstract: A safety system for protecting a ship and adjacent rocket motor rounds stored in the ship from a rocket motor inadvertently igniting includes a shock absorption and retention mechanism that is operative to catch and hold the igniter during inadvertent ignition and thereby prevent the igniter from blocking the rocket motor forward exhaust port which would eliminate the thrust neutral condition of the safety system and allow the rocket motor to break free from the fixture holding it and jeopardize the safety of the ship.

Abstract: A self-locking sheet-metal nut having a generally flat leg with an embossed thread portion for receipt of a screw and a pair of locking tabs resiliently and integrally connected to one end of said leg that extend over and are spaced from the leg. The tabs are approximately perpendicular to the axis of the screw and have clamping edges which are directed toward each other and form an opening downstream of the embossed thread portion that is smaller than the core diameter of the screw to be threaded into the nut. Upon turning of a screw through the nut, the clamping edges are forced apart and resiliently grip the core of the screw to lock it in place.

Abstract: A one-piece, resilient fastener clip especially useful for securing furniture shelving, and particularly metal shelving, to side supports via headed studs extending from the supports. The clip is preferably formed from spring steel and includes a pair of resiliently interconnected flanges for securing the clip to a downwardly extending end flange on the shelf. The flanges preferably include slots for slidably receiving a stud, inclined ramp means to draw the shelf toward the support, and a tab for holding the clip on the shelf. The clip allows the shelf to rest on the stud and includes releasable locking means in the form of a third flange resiliently interconnected with one of the other flanges and having a locking aperture therein which is receivable over the stud head. The clip pulls the shelf toward its support with a maximum force when the locking aperture is received over the stud head.
