An improved one-piece plastic bracket for supporting a sealer block of heat expandable reinforcement material on the substructure of a vehicle. The sealer block is adapted, upon being heated during an assembly line operation, to form a closed cell foam stiffener bridging a tolerance varying space between the substructure and an exterior panel. The one-piece bracket provides an initial function of readily supporting the sealer block in a snap-action manner on the vehicle substructure. Additionally, the bracket is operative to precisely guide the heat activated sealer into a predetermined foamed-in-place configuration wherein it sealingly bonds to both the substructure and the opposed inner surface of the panel.

The present invention relates to an arrangement for attaching a plastic panel to an automotive body metal substructure enabling controlled distortion free thermal expansion and contraction of the plastic panel relative to a metal substructure. The attaching arrangement comprises a plastic adjustable mounting block sized for initial insertion in an associated wide slot portion of a keyhole-shaped expansion and contraction slot. The block has a central abutment portion depending from an upper plate portion including lateral extending wings providing with the plate opposed grooves adapted to slidably engage a narrow trailing slot portion of the keyhole-shaped slot upon the blocks subsequent longitudinal rearward movement. The block has a vertically disposed longitudinally extending integral locating frangible finger extending longitudinally from the abutment portion adapted to engage the rearward transverse edge of the narrow slot portion allowing the precisely located block to be readily affixed by a fastener to the plastic panel. Upon the panel undergoing shrinkage the narrow slot portion transverse edge crushes the locating finger enabling the plastic panel and its associated blocks to slide fore and aft relative to the substructure to accommodate thermal movement of the panel.

The present invention provides an arrangement for attaching a flexible elastomeric panel integrally formed with one or more female connectors to an automotive body support surface having one or more associated male connectors in a blind assembly connection. Each female connector comprises a cutting-tooth shaped notch molded in an attaching flange of the panel while the male connector comprises a elongated stem projecting from the support surface. The elongated stem includes a backing plate positioned in parallel spaced relation to the support surface defining a layered gap therebetween. The panel flange is moved into flush contact with the support surface enabling the support flange to be received in a layer-like gap with the stem adapted to be received in a lean-in passage of the female connector. As a result the blind assembly connection is permitted upon the panel being slid relative to the support surface in a self guided manner whereby the stem is cammed into a retaining groove portion of the notch in a resilient snap-in manner.

The present invention relates to an improved arrangement for attaching a plastic panel and metal mounting strip sub-assembly to an automotive body metal substructure enabling controlled distortion free thermal expansion and contraction of the plastic panel relative to the mounting strip. The attaching arrangement comprises a metal spacing washer having a tubular sleeve portion formed with an integral frusto-conical spring flange. The washer sleeve portion free end extends through an elongated slot in the mounting strip and an aligned circular opening in the panel. A blind breakstem rivet is inserted through the washer bore and upon being set applies a predetermined axial clamping force biasing the washer flange into contact with the mounting strip. The rivet head undersurface may be provided with an annular locking ring adapted to engage the plastic panel out surface. Upon the panel being heated to its thermal-relaxation temperature the locking ring is embedded in the softened plastic panel thereby reducing excess load on the washer spring flange in a tolerance self-compensating manner.

A vehicle door outside handle housing is mounted in a door panel rectangular opening such that the housing peripheral lip flange portion is in flush contact with the panel outboard surface with the housing main portion inserted in the panel opening. A central hub extends inboard from the housing main portion with its principal axis aligned on the geometric center of the opening. The hub is formed with an external thread for engagement by the internally threaded lead-in collar portion of a piloted nut. A bent spring rod retainer in its unrestrained state is assembled between the inboard surface of the panel and the undersurface of the nut driving head. The spring rod retainer includes a looped central eye formation defining a semi-circular eyelet that is self-aligned on the hub axis and telescopically receives the nut collar. Upon threaded engagement the piloted nut captures the retainer and the housing in the panel opening. As the nut is tightened the spring rod retainer is axially compressed between the panel inner surface and the nut undersurface to induce a preload locking the nut against loosening such as by vehicle induced vibrations and the like.

A power driven screw driver self-gripping composite bit in the form of a pair of mirror image halved elements united at a common oblique interface providing a square end driver for reception in a screw head formed with a combined socket that accepts both a square end bit and a cross-point bit. Each halved element driver portion defines a trapezoidal cross section having major and minor parallel exterior side surfaces, a complete side surface extending at right angles to its major and minor surfaces, and a diagonal-like interface. The composite bit holder resiliently biases the halved elements interfaces into coextensive flush contact normally defining a square end driver. Upon threading torque being applied to the composite bit by a power screw driver the halved elements slip along their interfaces expanding the bit complete side surfaces in opposite directions so as to wedgingly engage their associated socket side faces into positive holding contact obviating slippage of the composite bit square end driver from the combined socket.

An arrangement for mounting a window glass sheet to a liftplate movable within a vehicle door. A plastic spacer bushing, having a through bore formed with an internal left-hand thread, is sandwiched between the glass sheet and the liftplate. A retainer assembly includes a plastic capped retainer, having an external left-hand threaded stem portion, and a metal T-nut. The T-nut head portion is concentrically anchored to the retainer cap portion with the T-nut tubular portion, having a right-hand internally threaded bore, telescopically received within the stem portion bore. The retainer stem portion is inserted through a hole in the glass sheet and is formed with its left-hand external thread engaging the bushing bore internal left-hand thread. The liftplate is secured to the glass sheet by a bolt having a right-hand threaded stem passed through a liftplate aperture for engagement with the T-nut internally threaded tubular portion. Upon initial tightening of the bolt the flex ring is readily deformed for flush tight contact of the spacer rim with both the glass sheet and the liftplate. The counterclockwise tightening of the bushing left-hand thread on the stem portion obviates slippage of the retainer during clockwise torquing of the bolt. Further, the bushing rim portion clamping load is removed from the edge of the glass sheet hole thus obviating glass sheet breakage.

A mounting arrangement and method of manufacture for clamping synthetic resin panels to a workpiece such as a vehicle metal substructure. A composite joint pad has a plate-like metal bushing pre-molded therein. The bushing comprises a raised central embossment having an exposed portion terminating in an arcuate sectioned rim extremity positioned a predetermined distance outwardly from the bonding face of the pad. Upon the bushing exposed embossment being received in a panel aperture, the pad's face is bonded to a panel mating surface with the rim flush with an adjacent surrounding surface of the panel. This enables the pad's arcuate sectioned rim to be clampingly attached to the substructure by means of a threaded fastener being overdriven in the bushing stem without causing stress on the panel.

The present invention relates to improvements in a self-bonding fastener and to a novel method of curing the bonding material during assembly line fabrication of sheet metal products. The fastener includes a headed self-threading screw member having its head undersurface formed with an annular axially extending lip. An upper portion of the screw thread is precoated with a thermo-setting adhesive which, when heated, will uniformly bond the fastener to a sheet metal plate. As the fastener is threaded through an undersized hole in a sheet metal member, such as an automobile body, the adhesive reliquifies and is stripped from the screw thread. The adhesive is then re-deposited uniformly to completely fill a closed chamber defined between the head undersurface and the opposed sheet metal surface sealed on its periphery by the annular lip which defines the axial dimension of the adhesive thickness. As a final step, the adhesive may be cured as an adjunct to the assembly line travel of the vehicle body through a final paint-drying oven cycle.

A protective flexible trim molding strip for attachment to an automotive body fascia panel. A plurality of metal gromments, each in the form of an eyelet tubular sleeve, having their outer circular head flanges cemented in a recess on the back of the molding strip. A retaining metal disc is received on each sleeve free end by means of a centrally located hole of a predetermined diameter for close contact with the sleeve outer diameter. The sleeve free end is compressed by a suitable tool applying a transverse pinching force. This force laterally expands the sleeve providing a bulbous portion capturing the disc to retain the plastic strip on body panels of varying thickness while obviating dimpling of the strip.
