Definitions

  • This invention relates to a shutter of the kind which comprises a series of inter-connected strips which extend laterally of the shutter so as to provide a flexible form of shutter or door capable of negotiating bends during its opening and closing operation.
  • Shutters of this kind are used as closures for boxes and containers such as cassettes containing bank-notes, vertical filing cabinets, and for doors for garages, lock-up shops etc.
  • An object of this invention is to provide a shutter which is inexpensive to manufacture, has a minimum of parts, and is substantially.tamper-proof when used in appropriate circumstances such as when used as a cassette. door.
  • a flexible shutter comprising a series of inter-connected strips which extend laterally of the shutter, each strip having at each end integral male and female connecting members whereby the strips may be joined in series to form the shutter, each strip also comprising a recess running the length of the strip adapted to receive a corresponding overlapping portion of an adjacent strip.
  • the strips are . preferably individually formed by injection moulding.
  • the individual strips are formed from plastics material.
  • the strips may be reinforced by embedding reinforcement wires or reinforcement strips in the individual injection moulded plastic strips.
  • Each of the strips may be formed with a protruding tongue and a recess so positioned that when the strips are joined at their ends the tongue of one strip enters the recess of an adjacent strip so as to interlock the strips to prevent tampering and to allow flexibility of the strips.
  • the male and female connecting members are formed adjacent shoulders at the ends of the strips so that when the male and female connecting members are engaged relative lateral movement of the strips is prevented.
  • the shutter may be used as the door of a cassette, particularly a cassette intended to contain bank-notes, and in this case the ends of the strips forming the shutter are preferably engaged in guides at each side of the cassette so that the male and female connecting members are totally enclosed within the guides.
  • FIG. 1 is an isometric view of a bank-note cassette having a shutter door made in accordance with the invention
  • bank-note cassette shown in Figure 1 is shown in more detail in our published UK Patent Specification No. 2039264A.
  • the cassette is in the form of a strong box 6 which has at one end a shutter 7 formed of a number of strips 8 made in accordance with the invention.
  • the lateral ends of the strips forming the shutter are when the shutter is closed engaged in guides 9 and 10 at the sides-of the cassette.
  • the guides are of U-shaped sections so as to receive the ends of the shutter.
  • the cassette is arranged so that when it is put into an appropriate machine a pair of rods 11 and 12 enter the cassette and operate mechanism to open the shutter.
  • FIGs 2 and 2A a single moulded plastic strip adapted to form a shutter in accordance with the invention.
  • the strip 13 is shown broken into three parts for convenience of illustration but it will be appreciated that the three parts are injection moulded to form a single unitary strip with integral male and female connecting members 14 and 15 at each end of the strip as shown in Figure 2.
  • These connecting members are formed adjacent a shoulder 16 so that when the connecting members are joined together the shoulder 16 prevents relative lateral movement of the strip because the inner surfaces of the female members 15 engage the shoulders 16 on adjacent strips.
  • a recess 17 (Fig.2a) and.a corresponding extension portion 18 so that when the strips are engaged to form a shutter the portions 18 lie in adjacent recesses 17 on adjacent strips thus forming a uniform shutter surface and preventing or substantially preventing tampering with the shutter.
  • FIG. 3 A portion of the guide 9 is shown in Fig. 3 and also somewhat diagrammatically in Figure 4 with one end of the shutter shown contained within the guide. Portions of the ends of the strips forming the shutter are shown broken away and in sections to illustrate the way in which the male and female members are contained totally within the guides 9 and 10 and to illustrate the way in which the strips bend to follow the contour of the guides.
  • the male and female members at the ends of the shutter are contained within these guides and can be dimensioned so as to be a very close fit in the guides with virtually no play, the 'wear on the shutters is restricted.
  • the injection moulded plastic strips are very inexpensive and thus the total cost of producing a shutter may be reduced by making use of this invention.
  • the material used for the injection moulding of the strips is preferably glass filled acetal or nylon.
  • the strips 13 may be reinforced by embedding elongated reinforcement members such as Nylon cord, metal strips, rods or wires or glass or other fibres in the strips 13.
  • elongated reinforcement members such as Nylon cord, metal strips, rods or wires or glass or other fibres in the strips 13.
