Abstract
Abstract A swinging arm door control mechanism is provided suitable for use for positioning a slide block for guiding the lower edge track of a sliding plug door of a vehicle, the mechanism including a swinging arm which has a cam track and a cam member, the swinging arm being rotatable to swing inwardly and outwardly of the side of a vehicle about an axis which is fixed relative to the cam member, driven by a common cam follower member which moves the swinging arm cam track by virtue of the constraints of the cam member.
Description
l~S;~73 This invention relates to sliding plug door mechanisms and relates especially to a swinging arm door control linkage f or use in such mechanisms r In sliding plug door mechanisms for railway vehicles, it has been proposed to provide means whereby a vehicle door is arranged to, when open-ing or closing, travel along the outside of the vehicle and in the proximity of the closed positio~ of the door, the mechanism providing for lateral movement of the door towards and away from the car so that the door in the closed position plugs into or at least against the door opening.
In such mechanisms, it has already been proposed to provide most of the controlling pa~ts in a recess at the head of the vehicle door and to provide a swinging arm link at a lower point, preferably beneath the thres-hold, which provides a lateral steadying and/or locking effect for the door whilst sliding away from and towards the plugging position.
According to the invention it is proposed to provide a swinging arm door constraining device including an arm pivoted at one end in a 1 housing and having spaced from the pivot point a part projectable from the .~! housing for connection to a door, said arm carrying a first track and said ~j housing carrying a second track, said tracks mutually crossing at respective ,'7 different points for different positions of the arm and a drivable member ;1 20 engaging both said tracks and thereby positively determining the positio~ of said arm.
Preferably, in the or each of twa extreme positions of the pivoted arm, a force e~erted on the arm tending to rotate it is countered by a reaction betwee~ the first track, the driveable member and the second 3 track substantially normal to the tracks to provide a locking action.
In order that the invention may be more clearly understood and 3 readily carried into effect, the same will be further described by way of '7~ example with reference to the accompanying drawing which illustrates in cut-,~
~ away diagrammatical form, a swinging arm co~trol mechanism in accordance 1 30 ~ith o~e embodiment of the invention.
Referring to the dra~ing~ this shows in part a rail vehicle sliding plug door t~e outer panel of which is denoted b~ reference 1 and the inner ~3 ~
~, , .
.: ; .
,: .. . .
105~'~73 panel of which is denoted by reference 2, the door being ~ypically of aluminium with a suitable core filling, Between the panels there is a slipper block denoted by reference 3 which runs in a longitudinal track (not shown) in the door panel which is carried o~ a pivot pin 4 at the outwa~d end of a projecting part of a swinging arm 5 which in its turn is rotatab~y pavoted to a fixed pivot point 7 in a housing formed beneath the threshold 8 of the car door opening one pillar 9 of which is shown. me upper surface of part of the threshold is shown cut-away to reveal the parts beneath and it will be seen that positively located beneath the cut-away part is a cam member, namely a plate 10 fixed in the housing having therein a cam slot 11 which forms a track, within which a driveable member follower 12 is slide-able and is carried on the end of a curved linkage 13 connected at a pivot 14 to a drive member lS in the form of a crank mounted at the lower end of a stub shaft 16 journalled in the door opening threshold at the forward corner thereof. The linkage 13 is curved to clear in operation the further ~ -fixing stud 17 which positively locates the plate 10 against rotation about t the pivot point 7 which carries the swinging arm. The swinging arm itself is also provided with a cam slot 18 which also forms a track and has the configuration shown. The relationship between the cam form of the slot 18 and the cam form of the cam slot 11 in the plate 10, positively determines the motion characteristic of the swinging arm 5.
Whilst not shown in the drawing, the plate 10 which is uppermost in the mechanism, is duplicated by a further identical cam plate, lowermost in the apparatus and the driveable member 12 is also similarly duplicated ¦ to provide a positive effort against the swinging arm between the two cam ~¦ plates. Additionally, the linkage 13 is duplicated to provide one such link-J -age on either side of the drive member 15 to again provide a true lateral thrust to the pivot 14. Furthermore, the pin forming the pivot 14 is pro-videt with end pads of nylon or other suitable material for the purposes of locating it between pro3ections throughout the range of its operational motlon.
In operation of the s~inging arm control device, the member 15 is .~ , .
105;~73 angularly moveable on a stub shaft 16. The stub shaft 16 is connected by a torque rod extending from drive means at the head of the vehicle door open-ing, through a suitable universal joint. Such a torque rod is shown as reference 41 in ~igure 2 of the specification of a co-pending Canadian Patent Application No. 267,378. The stub 16 is thereby rotated clockwise during unplugging of the door, and anti-clock~ise during plugging by the door operating mechanism (not shown)~ At commencement of unplugging of the vehicle door by the sliding door mechanism which is provided at the head of the door opening, the plugging edge 21 of the door moves outwards at least at its upper edge as a result of the unplugging effect of the mechanism provided at the head of the door and the drive mechanism drives through the torque rod to rotate the stub shaft 16 in the clockwise direction as shown by the arrow, thereby driving the driveable member 12 through the drive arm 15 and the linkage 13 in the direction shown by the arrows. Since the cam plate 10 is positively located, the member 12 can travel only along the cam slot 11 and a resultant of the motion is therefore imparted to arm 5 because of the relationship between the cam slot 11 and 18. This motion initially is negligible whilst the cam 12 moves away from its end positions in both the cam slots and thereafter motion takes place in the direction of the arrow to unplug and laterally position the lower edge of the door. When the cam ~l' follower 12 reaches the end of the two ca~ slots, any reaction through the swinging arm S is generally normal to the reacting surfaces of the cam slots 11 and 18 and therefore in tha$ position, the arm 5 is positively positioned.
Subsequent longitudinal sliding of the door is permitted by the block 3 being able to travel along the aforementioned track in the door and the door is ~-~ thereby positively supported against lateral movement relative to the side of the car. The reverse operation takes place during closing motion when the swinging arm linkage returns to the position illustrated.
Again, it will be seen that by virtue of the relationship between 3Q slots 11 and 18 the arm is again positively positianed in the closed position of ~he door.
For the purposes of facilitating the setting up of doors mounted in , 3 . :
lOS3Z73 a doorway on a sliding and plugging door mechanism according to the above description, the fixing stud 17 may incorporate an eccentric bearing or other adjustable locking means such that, by means of a suitable tool, rotational or sliding adjustment of 17 can set the mechanism a small distance inward or outward of the doorway in precise fashion.
