Definitions

  • This invention relates to hinge switch arrangements in which an electrical switch is operated on relative angular movement of the hinge leaf members and the object of the invention is to provide an improved construction of such a hinge switch arrangement primarily for safety or isolation purposes but also capable of other uses such as in a security system.
  • a typical practical application of the hinge switch is to the hinged door or cover of a cabinet or other enclosure containing electrical equipment whereby electric current supply to the latter is automatically cut off on the door or cover being opened e.g. by a service or maintenance engineer requiring access to the equipment.
  • a further object of the invention is to provide means whereby the hinge switch can be readily adjusted or preset for required operation. Whilst another object is to provide an arrangement in which the possibility of the switch being over ridden is avoided or largely minimised.
  • a hinge switch arrangement comprises a pair of hinge leaf members pivotally inter­ connected by a hinge pin, one of said hinge leaf members receiving accommodated or enclosed therein or thereon a switch and also carrying switch operating means cooperating with the hinge pin which latter is formed to actuate, or permit actuation, of said switch operating means on rotation relative thereto for corresponding operation of the switch, said hinge pin, in use, being fast with the other of said leaf members whereby turning of the hinge pin therewith on relative angular movement of the hinge leaf members effects or permits said actuation of the switch operating means.
  • the hinge assembly 1 comprises a hinge body 2 and hinge flap 3, respectively providing the hinge leaf members which are interconnected by a hinge pin 4.
  • the body 2 is normally attached to a fixed member, such as a door frame pillar, whereas the flap 3 is fixed to a hinged closure member such as the door of an industrial cabinet or enclosure.
  • the hinge members 2 and 3 are provided with fixing bolt holes such as 5 but may be otherwise mounted in position of use.
  • the body 2 has a knuckle 6 with a vertical pivot bore 7 in which the hinge pin 4 turns, the latter when in use being fast with the flap 3 which has upper and lower knuckles 8 and 9 between which the knuckle 6 is received.
  • Spacers 10 and 11 between the knuckle 6 and the knuckles 8 and 9, respectively, also act as thrust washers.
  • the upper knuckle 8 is split and provided with a cap head screw 12 tightening of which clamps the hinge pin 4 to secure it fast with the hinge flap 3 in an adjusted angular position.
  • the screw 12 engages a peripheral groove 13 in the pin 4 in the manner of a cotter to also provide axial location of the pin 4.
  • the pin 4 has two spaced peripheral grooves 14, positioned within the bore 7, which house O-rings 15 for sealing purposes in respect of the switch operating arrangement which will now be described.
  • the rear of the hinge body 2 has a sealing gland 16 for an electrical cable 17, providing appropriate circuit connections to a switch S.
  • the switch S is operated on hinge movement in either direction from a predetermined angular position, which is fully adjustable throughout the full range of hinge movement as later described.
  • the switch S is mounted within a recess 18 in a housing 18a on the hinge body 2, being positioned behind a removable cover plate 19 (Fig. 3) which is normally secured by screws 19a to the housing 18a but is shown removed in Fig. 1 to reveal the switch and switch-operating arrangement.
  • the switch S is shown of the micro-switch type, which would usually control heavy duty isolation switch means such as a coil contactor in effecting safety cut out operation of the latter.
  • the switch S is operated by a lever in the form of a rocker 20 within the recess 18 alongside the switch 2.
  • the rocker 20 pivots on a pivot post 21 under the opposite actions of a return spring 22 and a switch-operating plunger 23 axially slidable in a bore 24 in the body 2.
  • This bore 24 is disposed radially of the hinge pivot bore 7 and extends between the latter and the recess 18.
  • the plunger 23, see particularly Figs.6 and 7, has an inner end 25 which seats in the rocker 20 and acts against it, and an outer end 26 shaped to seat in an axial recess or groove 27 formed centrally in the pivot pin 4 midway between the O-ring grooves 14.
  • the return spring 22 moves the rocker 20 to a resting position shown in full lines in Figure 1 in which the switch 2 is in the operative condition in which the contacts C are closed.
  • the plunger 23 rides out of the groove 27 and runs on the plain cylind­rical peripheral surface of the pin 4 during said hinge angular movement.
  • the hinge pin 4 is adjustable through 360° and in relation to the full range of angular movement of the hinge members 2, 3 to obtain adjustment of the operation of the switch at any desired hinge position according to operating requirements.
  • Angular setting of the hinge pin 4 also depends on the manner in which the hinge is mounted in position of use when the door is closed e.g. in the flat or opened out condition shown in Figures 1 and 2 or when the mounting body 2 is turned at an angle to the flap 3 in the door closed condition.
  • the hinge described and shown is capable of relative angular movement of the hinge leaf members 2, 3 through substant­ially 270° and for this purpose the flap 3 is shown recessed at 30 to accommodate the switch housing 18a when the hinge members 2,3 are fully closed together.
  • Bushes of anti-friction material such as PTFE (polytetra­fluoroethylene) may be provided about the hinge pin 4 as necessary.
