Definitions

  • the present invention relates to anchor mechanisms generally and more particularly to self-locking anchors used in safety restraint systems.
  • Quick connect anchor mechanisms as disclosed in US 7,413,321 have a shoulder bolt or fastener with an enlarged head adapted to slide into a keyhole type opening having a large opening to receive the head and a narrower opening to receive the shoulder as it is slid into the narrow opening wherein a tab locking mechanism can engage an opening in the head to hold it in place.
  • This prior art design allows the assembly of the anchor to the shoulder bolt quickly and easily.
  • a co-inventor of this prior art device has developed an improved robust anchor with a self-locking feature that can be used in virtually any application for a quick connecting anchor mechanism.
  • the inventive device is self-locking and remarkably strong as described below.
  • a quick connect anchor is provided with a self-locking feature.
  • the anchor includes a plate and a deflectable cap partially covering the plate.
  • the plate has a top and a bottom side and a fastener opening.
  • the plate is configured to be placed over a fastener and moved in a first direction from a free or unlocked position to a locked position where the plate is locked to the fastener.
  • the deflectable cap has a central opening to receive a fastener, the cap being moved upward upon interaction with the head of the fastener.
  • the cap is affixed flush to one end of the plate near the locked position and is unattached and deflectable relative to the plate near the first position partially overlying the plate fastener opening.
  • the invention can further be a combination including the quick connect anchor and the fastener.
  • FIG. 1 is an exploded view of the quick connect anchor assembly of the present invention.

  • the quick connect anchor assembly 10 has a plate 12, a cap 20 fixed at one end to the plate 12 using rivets 30.
  • the cap 20 has an annular or somewhat U-shaped lower portion 22 and an upper deflectable portion 24 that includes the sidewall 21 and the bent legs 25.
  • the rivets 30 pass through holes 23 in the lower portion 22 of cap 20 and holes 13 in the plate 12 to make a secure attachment at one end portion 15 of the plate 12.
  • the plate 12 is bent at a forward end location 14.
  • the plate includes an opening 19 through which the connecting member such as a webbing, cable, wire or rope of a seat belt can pass and be secured thereto.
  • the plate 12 has another opening 18.
  • This opening 18 is in a keyhole type shape having a large diameter 18a with a lower extending narrowed portion 18b. Adjacent to and below the anchor connector a fastener 100 is shown. The fastener 100 is adapted to pass through the large diameter of opening 18 through the bottom of plate 12. Upon relative movement of the plate and fastener, the fastener will move into the locked position when entering the narrow portion 18b of the opening 18.
  • the cap 20 has a sidewall 21 that partially extends around an upper perimeter of the cap 20.
  • the sidewall 21 extends only a distance of about 180 degrees, preferably less than 180 degrees, around this perimeter and the cap is connected by angled or bent legs 25 on each side of the opening 28 of the cap 20.
  • a top view shows the cap 20 partially covers the opening 18.
  • the deflectable portion 24 of cap 20 is lifted by the fastener head 110.
  • the angled/bent legs 25 bend or deflect upon interaction with the fastener permitting deflectable portion 24 of the cap 20 to deflect.
  • the fastener head 110 lifts the cap 20 as it enters the opening 18 and as it is pushed forward the entire head 110 of the fastener 100 is able to pass the deflected portion 24 of the cap 20. Once the head 1 10 clears the deflected portion 24, the cap 20 will snap back toward the plate to its normal undeflected condition.
  • the fastener 100 is illustrated in the free or unlocked position and the locked position.
  • the fastener 100 is shown in the free or unlocked position wherein the head of the fastener 100 is in opening 18a lifting part 24 of the cap 20.
  • the fastener 100 is moved from an initial entry point towards the narrow opening 18b, but with the cap 20 deflected and resting on the tope edge of the head 110 of the fastener 100.
  • the fastener 100 is located in the narrow portion 18b of opening 18.
  • a unique feature of the present device is the peripheral sidewall 21 positioned along a portion of the outer perimeter of the cap 20 near the first position.
  • the sidewall 21 along with the bent legs 25 elevate the deflectable portion 24 so it is aligned and slightly below the top of the head 110 of the fastener 100. This elevation limits the amount of deflection required of the cap deflectable end portion 24.
  • the sidewall 21 has a height, preferably less than the thickness of the head 1 10 of fastener 100. This allows the cap 20 to lie below the top of the head 1 10 against the side or edge 11 1 of the head 110 when the fastener 100 is fully inserted and the deflectable portion 24 returns to its initial position.
  • the opening 18 is similar to a keyhole having a large diameter portion 18a and a narrower opening portion 18b for receiving the bolt or fastener 100.
  • This rigid component can be made of metal or any suitable material and preferably has plastic lining features surrounding the perimeter of the opening 19 to limit any fraying of any belt or webbing that would pass through this forward portion 14 of the anchor plate 12.
  • the cap 20 preferably is made of metal, preferably thin sheet metal or most preferably stainless steel as an anti- corrosion material.
  • the fastener 100 is shown as a shoulder bolt, it is possible any form of fastener could be used with the present device.
  • the invention is most suitably used as a quick connect anchor assembly 10 as part of a restraint assembly 200.
  • the restraint assembly 200 is a seat belt assembly.
  • the seat belt assembly 200 includes the quick connect anchor 10 and fastener 100 and seat belt webbing 202 which is looped through the opening 19 and is connected to a buckle assembly 203 with a buckle sensor 204.

Abstract

L'invention concerne un ancrage (10) à raccord rapide comportant une caractéristique de verrouillage automatique et qui est destiné à être fixé à un élément de fixation (100). L'ancrage comprend une plaque (12) et un capuchon (20) déviable qui recouvre partiellement la plaque (12). La plaque (12) comporte une face supérieure et une face inférieure et une ouverture (18) d'élément de fixation. La plaque (12) est conçue pour être placée par-dessus l'élément de fixation (100) et pour être déplacée dans une première direction, d'une position libre à une position verrouillée. Le capuchon (20) déviable comporte une ouverture centrale (28) destinée à recevoir un élément de fixation (100). Lors de l'insertion de la tête (110) d'un élément de fixation, le capuchon (20) est dévié à l'opposé de la plaque (12) par la tête (110), ce qui permet à la tête de l'élément de fixation, lorsque celui-ci est mis en position verrouillée, de se dégager du capuchon (20) et de pénétrer dans l'ouverture centrale (28) à mesure que le capuchon (20) revient brusquement au-delà de la tête pour se verrouiller avec l'élément de fixation sous la partie supérieure de la tête (110).
