Definitions

  • the present invention generally relates to an anchoring assembly and a remotecontrol assembly.
  • Conventional remote-control assemblies for transmitting motion along a path include a conduit defining a conduit interior and extending along an axis, a core element disposable within the conduit interior and moveable along the axis for transmitting motion along the path, and an anchoring assembly.
  • Typical anchoring assembly assemblies a support body defining a support opening along the axis for supporting the conduit.
  • Typical anchoring assemblies also include a retainer disposable in the support opening and supportable by the support body. The retainer further supports the conduit.
  • Typical anchoring assembly further includes a retainer clip coupled to the support body and the retainer for securing the retainer to the support body and, therefore, securing the conduit to the support body.
  • typical anchoring assemblies are often difficult to assemble and disassemble for a variety of reasons.
  • various components of typical anchoring assemblies such as retainer clips, are typically required to have a specific alignment and clamping force to adequately secure the retainer to the support body.
  • current anchoring assemblies require a specific orientation of the support body, retainer, and retainer clip, which can often lead to increased assembly time.
  • current anchoring assemblies can be difficult to disassemble based on current designs of the support body, retainer, and/or retainer clip.

Abstract

L'invention concerne un ensemble de commande à distance comprenant un conduit, un élément central et un ensemble d'ancrage. L'ensemble d'ancrage comprend un corps de support définissant une ouverture de support et un élément de retenue. L'élément de retenue définit une ouverture d'élément de retenue et une rainure d'élément de retenue et le corps de support peut être reçu à l'intérieur de la rainure d'élément de retenue. L'ensemble d'ancrage comprend en outre une attache d'élément de retenue jetable entre le corps de support et l'élément de retenue dans la rainure d'élément de retenue. L'attache d'élément de retenue comporte un premier et un deuxième bras d'attache définissant une ouverture d'attache et pouvant se déplacer entre une position déployée et une position contractée. L'attache d'élément de retenue et/ou le corps de support possède une cale qui est prise en sandwich entre le corps de support et l'élément de retenue lorsque l'attache d'élément de retenue se trouve dans la position contractée. L'attache d'élément de retenue est configurée pour empêcher un mouvement axial et radial de l'élément de retenue par rapport au corps de support lorsque l'attache d'élément de retenue se trouve dans la position contractée.
