Definitions

  • the present invention relates to a releasable fastener and to a receptacle.
  • support will in general be used by convention to mean any item to which a receptacle of a fastener is in use fixed.
  • a support may be for example a cabinet frame or a door frame.
  • panel will in general be used to mean any item that is to be fastened to a support.
  • a panel in general may or may not be planar.
  • a panel may be for example a cabinet or other door.
  • the terms "panel” and “support” should be taken to include such articles as planar or near-planar sheets (such as vehicle body panels, cabinet doors, etc.), and non-sheet-like articles (such as cabinet or other door frames, vehicle spare wheels, etc.).
  • a well known type of releasable fastener is the so- called "quick-acting fastener", which is typically of the so-called quarter-turn type.
  • An example of such a fastener is disclosed in US-A-3169293.
  • This fastener has a hollow cylindrical receptacle, which in this example is fixed to a support by means of an external screw thread on the receptacle, and a stud.
  • the stud has a transverse locking element at one end, such that this end of the stud has a generally T-shape.
  • the T-shape end engages with cam surfaces having locking detents provided at the end of the receptacle.
  • the stud By turning the stud through an appropriate amount, the stud can be locked into and unlocked from the receptacle.
  • a spring is provided between the stud and the receptacle to bias the stud and receptacle apart. Thus, a panel can be fastened to the support.
  • a disadvantage of known quick-acting fasteners of these types is that access is required to both sides of the support in which the receptacle is fixed during the fixing process.
  • the receptacle is first inserted from one side of the support so as to protrude through a hole to the other side. Then a welding or other fixing process occurs that requires access to the other side of the support. Finally, the stud is inserted from the first side and, in use, pulls against the weld or other fastening.
  • a typical blind rivet has a generally hollow cylindrical shape with a radially outwardly protruding flange at one end.
  • a blind rivet typically clamps two members together and is secured to the members by first passing the rivet through holes in the members so as to cause the flange to abut one (outer) side of one of the members. A part of the cylindrical portion is then deformed to provide a second radially outwardly extending flange on one (outer) side of the other member so that the members are trapped between the two flanges and thus clamped together. An insertion tool is used to secure the rivet in this manner.
  • the main advantage of blind rivets is that they can be emplaced from one side only of the members.
  • a blind rivet nut is a blind rivet having a securing means, such as an internal screw thread, to which a stud can be fitted.

  • the stud ⁇ is made of metal and is initially formed with a shank 9 of uniform cross- sectional shape along its length.
  • the crosspiece 10 is formed by stamping either side of the shank 9 at one end, which deforms that end to form the crosspiece 10.
  • the crosspiece 10 is generally of a flat arrow shape.
  • the receptacle 2 in this example is generally in the form of a cylindrical hollow body of circular cross- section. Other cross-sectional shapes, such as hexagonal, square, etc., are also possible.

  • the other end of the receptacle 2 is provided with a stud-engaging portion 13.
  • the stud-engaging portion 13 is provided by two substantially identical cam surfaces 14.
  • Each cam surface 14 has a helical cam surface portion 15 which extends for approximately 90° around the end of the receptacle 2.
  • a notch or detent 17 is provided at one end of each helical cam surface 15.

  • This can be achieved by using an insertion tool of known type, as described generally above.
  • this securing of the receptacle 2 to the support 1 can be facilitated by providing the insertion tool with a screw-threaded mandrel which can be screw fitted to the screw thread 18 of the receptacle 2.
  • This screw threading of the receptacle 2 to the insertion tool provides for a much more secure mounting of the receptacle 2 to the insertion tool than is provided by some prior art arrangements.

  • the stud 6 In order to clamp the support and panel 1,4 together, the stud 6 is rotated by an appropriate angle, such as between approximately 90° and 130°. This can be facilitated by providing a slot 20 in the head 8 so that the blade of a screwdriver or similar can be inserted, or by other shaping of the head 8.
  • the crosspiece 10 rides up the helical cam surfaces 15 and then drops into the detents 17. Because of the riding up on the helical cam surfaces 15, which provides a mechanical advantage, pull-up is achieved.

Abstract

L'invention concerne une fixation libérable du type à action rapide, qui comprend un socle de fixation creux (2) et un goujon (6). Le socle de fixation (2) comporte une bride (12) qui s'étend radialement vers l'extérieur à une extrémité; une partie en prise avec le goujon (13) à l'autre extrémité; et une partie de paroi déformable (11) située entre les deux extrémités. La partie de paroi déformable (11) peut être modifiée pour former une seconde bride s'étendant radialement vers l'extérieur (19), de sorte que, pendant l'utilisation, un support (1) puisse être retenu prisonnier entre la première et la seconde brides (12, 19) pour fixer le socle de fixation (2) au support (1). Le goujon (6) comprend une tige (9) munie d'une tête (8) à une extrémité et d'une partie en prise avec le socle de fixation (10) à l'autre extrémité pour s'accrocher à la partie du socle de fixation (2) en prise avec le goujon (13) afin de verrouiller ce dernier (6) au socle de fixation (2). La partie du socle de fixation (2) en prise avec le goujon (13) et la partie du goujon (6) en prise avec le socle de fixation (10) sont arrangées pour assurer une traction entre le goujon (6) et le socle de fixation (2) lorsque le goujon (6) est verrouillé au socle de fixation (2).
