Definitions
- Thisinvention ⁇ rela-tes to treadle controls ⁇ orfdoors.
- One of the obj ectsofthis invention is' -to provide apparatus tdisposed in passageways obstructed by doors adapted vto beoperate'd by the passageof a person therethrough' to cause said doors to operate.
- Another object of this invention is the f provision of apparatus -as mentioned above-adapted to'cont-rol the oper- LU ation of the doors regardless of the direction of passage of pedestrians therethrough.
- Another object of the invention is theprovision of Vtreadle contrlleddoors in passageivvays,' .Which are 'driven by motive means con* 15 ⁇ nected to the powercircu'it ofthe lbuilding in which it is used.
- a still further object of the invention is the provision of devices adapted to be energized bythe depression ofA pivoted3 treadlejplates 2g Adisposed in theloor ,ofthepassageway to cause theV doors to open.
- Vobject of this f invention is the provision of apparatus 'of thisk type, vvhich W. issi-mple and easy to construct and eiiicient in u operation and maintenance. Y
- Figurey 1 is a sideelev'- vational view of a barrier disposed in the passageway'dsclosing the motive lmeans for operating it. l
- Figure 2 is a' horizontal cross-sectional vieW of "Figure l, showing the motive means in dotted lines.
- Figure is a. top, plan view of thetreadle structure and a .cross-sectional view Voit-.fthe barrier disclosed in the passageway.
- Figure 4 isa Wiring diagram of the devices employed.
- the main featuresl comprise a treadle Vdisposed in 'the'fioor' of' the passageway,Y which in the preferredformis sectionlized.
- the treadle j plates are lpivote"d-ax1fd are4 adapted upon ldepression by the vWei'g'gl'itofa Vpedestrian thereon' to 'close' aci-rcuit to the-electric motive means disposed f above thebari'iers.
- the section 51 is securedi by meansfof 'the' idoor straps '52v yto the rotatable vertically v-inounteid shaftf 53.
- On -the outer-end of lvdoor'section 150 is secured the mounting'ff'or the door-guide roller 56 Whichtravels' in -an"d'is guided: vby the member 57.
- a treadle plate '63Which Vis-pivotally* mounted at one side onfthefelement 64.
- lDisposed-ladjacent'the ⁇ free endf ofi the treadlep'late isi-a square shaft-'166, which .ismounted so as to f be rotatable.
- Mounted at intervals on the shaft 66 are the short lugs 69 projecting under the free depressible ends of the sections of the treadle plate, so that when the free end of any section of the treadle plate is rotated downwardly it engages with one of the lugs on the shaft 66 to cause it to rotate through a portion of a revolution.
- an arm 65 In all the barriers or doors, there is attached to the shaft 66, an arm 65, the free end of which operates through the switch S secured to the door frame 8l.
- the best form of construction comprises a treadle plate made up of a plurality of sections as is shown in Figure 3.
- the sectionalized form is more sensitive because the sections are lighter and are easily operated even by the weight of a child. The door remains open as long as any one treadle plate remains depressed.
- rlhe Switch S comprises a vertical slidable rod 67 having mounted therein the switch fingers or bridging members 7l, 72, 73, 74, 75 and 76.
- a spring 68 mounted on the lower end of the shaft 67 is a spring 68, which maintains the switch in a position to cause the doors to be closed when no one is on the treadle plate 63.
- the knock out switches 77 and 78 Operating in conjunction i with this switch are the knock out switches 77 and 78.
- the switch 79 is inserted in the feed line and serves to disconnect the apparatus from the power source when desired.
- switch S will be shifted to its other position causing the fingers 76, 75 and 74 to bridge their contacts and at the same time causing lingers 71, 72 and 73 to move out of Contact with their circuit terminals.
- This operation of the switch merely causes reversal of the current in the armature circuit of the motor 60, causing it to operate in a reverse direction with a result that the doors open.
- the movement of the motor will cause switch 7 7 to close and switch 78 to open, at the end of the door movement, so as to interrupt the current to the motor.
- switch S under the inliuence of spring 68 returns to its normal position to reverse the armature current and cause the doors to close.
- FIG. 5 to 8 One form of such equipment is shown in Figures 5 to 8.
- I have shown the two passageways A and B. Disposed in the passageway A is a door comprising the two hinged sections 3 and 4 mounted on the vertical shaft 6.
- In the passageway B is a door comprising the two hinged sections 1 and 2 mounted on the vertical shaft 5.
- the shafts 5 and 6 are supported by the door frame 9.
- a crank 8 pivotally connected to the link 7, and at its other end is secured to the crank on the pneumatic motor 2O which may be one of the many known forms of pneumatic motors.
- the pivoted treadle plate 87 Disposed in the floor of the passageway is the pivoted treadle plate 87, which is mounted to rotate about the angle iron or plate 38. Under its free end are mounted springs 39, which are seated in the plates 40. Attached to the free end of the plate are the projections 4l, which contact with the lugs 42 secured to the shaft 43, which is pivotally mounted in the members 44. Keyed to the shaft 43 is an arm 45 which cooperates with the rod 27 on the switch which is slidably mounted in the brackets 29 and 30.
- the arm 45 moves the rod 27 upwardly against the action of the spring 3l to cause the bridging plate 28 to close the circuit to the contacts 35.
- the wires from these contacts are connected with a magnet valve which is well known in the art, and is usually used in conjunction with pneumatic motors. 'Ihis magnet valve admits fluid pressure to a valve puller which in turn permits fluid pressure to operate the pneumatic motor.
- the magnet valve and valve puller are so constructed that when the circuit to the magnet valve is broken a reversal of operation occurs and the engine moves back to cause the doors to close.
- the combination with a passageway having doors therein and electrically operated means for opening said doors, of a treadle comprising a plurality of sections disposed in said passageway with several sections on each side of the door and switch means operated by the depression of any of said sections for actuating said door opening means.
- an automatic door operating device the Combination with a passageway having doors therein and means for operating said doors, of a. plurality of plates in said passageway adapted to be displaced by the passage of a person through the passageway, a single switch adapted to be closed by the displacement of any one of said plates whereby said means is caused to open said doors, and
- treadle means in the passageway comprising a plurality of pivoted plates mounted in the iioor thereof on cach side of the doors, single switching means controlled by the depression of any plate for controlling said electric motor means to cause the doors to open, and means operated by the movement of the doors to break the circuit when the doors are fully opened or closed.
- an automatic door operating apparatus the combination with a passageway having a door therein and power means for operating said door, of a treadle comprising a plurality of sections disposed in said pas- Y sageway with several sections on each side of the door, and control means operated by the depression of any one of said sections for actuating said power means for operating said door.
