Definitions

  • Springs are used in injection and infusion devices that are preferred delivery devices in a variety of functions, such as a drive spring for a piston or other conveying member or as a return spring for a piston rod or other movable against the restoring force of the spring of the component of the device.
  • springs also serve only to support and fix or position one component of the device on or in another, by holding the spring in a tensioned state, one of the components in a particular position relative to the other, such as one of the components in FIG clamped a stop contact with the other. In this way, for example, manufacturing and assembly tolerances can be compensated.
  • the components of such devices are usually molded plastic parts. Most are injection molded parts.
  • Plastic springs and examples for their installation in devices for medical and pharmaceutical applications are known from DE 10 2005 032 705 Al.
  • the invention relates to a plastic spring comprising a spring seat which extends around a spring axis of the plastic spring, a first bracket and a second bracket.
  • the brackets extend around the spring axis in the circumferential direction to each of a first bracket end and a second bracket end, in which they each protrude from the spring seat in the axial direction.
  • the bracket ' are elastically bendable in the axial direction, they form in a side view of the plastic spring seen transverse to the spring axis extending elastic bending arms.
  • the spring seat may in particular be formed circumferentially about the spring axis as a retreating ring. Although less preferred, the spring seat can also be formed only as a partial ring and in extreme cases only two circumferentially short sections, of which the brackets protrude directly or via axially extending connecting webs.
  • the spring seat can be formed as an axially slender ring or axially slender sections, it only has to fulfill the function of the axial support of the plastic spring.
  • the plastic spring may also be molded to a component of the device that performs one or more functions within the device, such as a mechanism holder supporting a conveyor, preferably a drive portion of a fluid product delivery conveyor.
  • the Plastic spring can also be formed on a single functional component of such a conveyor or metering device, as they are basically known from such devices.
  • the spring seat serves to support the plastic spring, either a plastic spring, which is molded onto another functional component, or a plastic spring, which is present only as such and only fulfills the spring function.
  • the brackets can form an angle or have a polygonal shape in a plan view parallel to the spring axis; more preferably, the brackets are continuously formed in the circumferential direction around the spring axis, preferably partially circular, elliptical or otherwise oval.
  • the curvature of round brackets may fundamentally change according to the sign in the course of the respective bracket, more preferably the curvature does not change its sign, particularly preferably the curvature is constant and the respective bracket corresponding to the spring axis circular.

It is also advantageous in this respect if the brackets are axially supported on one another or on the spring seat or seats via axial connecting webs.

Alternatively, it can also be polygonal or partially round and partly polygonal.
  • the plastic spring is preferably molded from a thermoplastic material by injection molding. It can consist solely of a plastic material, alternatively For example, but also reinforcing fibers or other shaped elements to be embedded in a plastic matrix of the plastic spring.
  • the center of gravity of the plastic spring outside the axial center closer to one of the two axial ends than at the other is arranged.
  • Such a center of gravity arrangement is advantageous for automatic feeding of the plastic spring to a mounting device.
  • a feeding device can be formed in principle known as vibrating conveyor, in which the plastic springs supported by gravity successively fed to the mounting device and during feeding a feed chute or other shaped feeder is placed in vibratory motion, so that the plastic springs with axial align eccentric center of gravity with the heavier end down and thus with respect to the spring axis in a defined, reproducible axial alignment with the mounting device.
