Definitions

  • the present invention relates to an easily assembled pedal unit for operating microswitches or pneumatic valves.
  • prior pedal units used for operating microswitches or pneumatic valve, for driving several types of apparatus have a construction including a metal frame-work to which a pedal element must be pivotably connected, which pedal will drive said microswitch or pneumatic valve.
  • Another problem is that, mainly as electric component are used, such as microswitches or the like, there is necessary to provide a proper electrical insulation in order to provide the unit with a satisfactory operating safety.
  • the aim of the present invention is to overcome the above mentioned drawbacks by providing an easily assembled pedal unit for operating microswitches or pneumatic valves, which allows the component parts thereof to be easily and quickly assembled without using metal screws or insert elements.
  • a further object of the present invention is to provide such a pedal unit for operating microswitches or pneumatic valves which is very stable and can be supported firmly on a supporting surface without the need of providing a separate stabilizing element or assembly.
  • Another object of the present invention is to provide such a pedal unit which is very reliable in operation, can be easily made starting from easily available elements and materials and which, moreover, is very advantageous from a mere economic standpoint.
  • an easily assembled pedal unit for operating microswitches or pneumatic valves characterized in that said pedal unit comprises a bottom element supporting a driving element and including fork-shaped seats therein a pedal element can be pivotably engaged, said pedal element being provided with a leg portion cooperating with said driving element, an outer protecting casing being moreover provided in which said bottom element can be engaged and restrained by snap engaged means, for providing a stable pivotable coupling between said pedal element and fork shaped seats.
  • the easily assembled pedal unit for driving microswitches or pneumatic valves.
  • a bottom element generally indicated at the reference number 1, comprising a plate-like body 2, from a central region of which there extends a vertical wall 3 adjoining fork-shape seats 4 which are opened at the top thereof.
  • a driving or control element which can comprise either a microswitch 7 or a pneumatic valve 8.
  • a pedal element can be pivotably engaged, said pedal element being generally indicated at the reference number 10 and being provided with a pedal portion 11 from one end of which there extends a lug 12 which supports a cross pivot pin 13 which can be engaged in said seats 4.
  • a driving leg 14 which is provided for cooperating with the driving or control element consisting of a microswitch or a pneumatic valve.
  • urging resilient means operate which comprise a spring 20 abutting in a housing seat 21 formed on the plate-like body and in a corresponding seat which is formed on the bottom wall of the pedal portion 11.
  • the pedal unit further comprises a safety assembly 30 comprising a hook-like element 31 provided with an abutment tooth element 32 projecting through a window 33 formed through the pedal portion.
  • the pedal unit comprises furthermore resilient means, consisting of a spring 36, cooperating with the hook element 31 and an abutment or shoulder 37 which is formed on the framework 38, which can be housed, by introducing it from the bottom portion, in ear elements 39 applied on the plate-like body 2.
  • the bottom element 2 is housed in an outer protecting casing 40 which, at a bottom region thereof, is provided with side guides 41 in order to slidably engage the bottom element therein, said bottom element being provided with coupling resilient means consisting of resilient tabs 42 supporting a bottom projection 43 which is adapted to be snap engaged in corresponding holes 44 formed on the bottom of the outer protecting casing.
  • the outer protecting casing which has a box-like configuration, is so designed that, as the bottom element has been engaged inside said casing, the top portion of the casing will practically close the fork-like seats 4 so as to provide a stable connection for firmly pivotably connecting the pedal element and bottom element.
  • the pedal unit also comprises a ballast plate, indicated at 50, which can be engaged between the bottom element 1 and the inner bottom portion of the outer casing, so as to suitable increase the weight of the pedal unit to provide it with a good stability.
  • the several component elements of the pedal unit of the invention that is the bottom element, the pedal element and outer casing are made of a plastic material, thereby all of the electrical insulation problems are suitably solved, in addition to providing the possibility of making a very stable and long duration construction.
