For example, it is often desirable to install a hanger 12 on each of two opposite frame members so that a picture wire (or other support member) may be strung therebetween. If the frame member 14 has an asymmetrical cross-sectional profile, the desired relative positions of the hanger actuator 16, the frame member 14, and the workpiece support 76 will be different for each side of the frame. To accommodate both side frame members 14, the workpiece support 76 may be selectively moved to the desired position.

In the retracted position, the rod end 116 is not engaged with the hangers 12 within the magazine 22; i.e., the hangers 12 can slide toward the actuator end 96 of the magazine 22. In the extended position, the rod end 116 engages hangers 12 within the magazine 22, and thereby prevents the hangers 12 from moving toward the actuator end 96 of the magazine 22.

  • the flanges 48 are extensions of the midsection 38, rolled back onto the midsection 38.
  • the rounded edge created by the rolled-back edge provides the additional advantage of a smooth edge that is less apt to wear a member tied to the midsection 38.
  • This midsection 38 configuration lends itself to a stamping-type manufacturing process.
  • Alternative hanger 12 embodiments may include structural features other than the aforesaid flanges 48 to increase the strength of the web 34 mid-section.
  • the narrowed central section 46 provides advantage because it is operable to centrally locate a member tied to the midsection 38. As a result, the uniformity of positioning between hangers 12 is increased.

Depending upon the configuration of the apparatus 10, that distance may be fixed or adjustable. At a minimum, the distance permits the current framing material workpiece 14 to be inserted between the hanger actuator 16 and the base panel 62 (or bench).
  • the hanger actuator 16 is normally maintained in a retracted position; i.e., the piston 24 is retracted within the hanger actuator 16.

  • the actuator controller can be switched (e.g., by foot pedal, hand-operated switch, etc.) by the operator to cause a hanger 12 to be installed within the framing material workpiece 14.
  • the controller causes the piston 24 of the selectively operable hanger actuator 16 and the attached plunger 26 to extend outwardly and into contact with a hanger 12.
  • the piston 24 drives the hanger 12 out of the guide assembly 20. If the hanger 12 is part of a stack 52 of hangers 12, the process of driving the hanger 12 out of the guide assembly 20 causes the hanger 12 to separate from the stack 52.
  • the force of the hanger actuator 16 causes the one or more tabs 126 to shear, thereby separating the hanger 12 from the stack 52.
  • the retention mechanism 54 attaches the hanger 12 to the plunger 26 as the plunger 26 travels toward the framing material workpiece 14.
  • the hanger actuator 16 subsequently drives the hanger 12 into the framing material workpiece 14 disposed between the base panel 62 and the hanger actuator 16.
  • the amount the hanger 12 is driven into the framing material workpiece 14 can be determined by- the amount of force applied by the hanger actuator 16, or by the distance of the piston stroke.

Once that hanger 12 is installed, that workpiece support 76 is typically moved to a second position. Alternatively, that workpiece support 76 can be removed in favor of a second workpiece support 76.
  • the portable hand tool version includes an actuator and a magazine 22.
  • the actuator and magazine 22 are similar to those described above.

Abstract

L'invention concerne un appareil servant à mettre en place des éléments de suspension de matériel d'encadrement dans une pièce à travailler. L'appareil selon l'invention comprend un actionneur pouvant être mis en marche de manière sélective, un ensemble de guidage et un chargeur. L'actionneur comprend un piston. L'ensemble de guidage est destiné à guider un élément de suspension de matériel d'encadrement dans la pièce à travailler. Le chargeur est destiné à acheminer au moins un élément de suspension de matériel d'encadrement dans l'ensemble de guidage. Le fonctionnement de l'actionneur provoque l'entraînement par le piston d'au moins un des éléments à travers l'ensemble de guidage et dans la pièce à travailler.
