Description
li41~36 Sliding door, especially for train cars and buses At present, sliding doors are increasingly used in vehicles. During opening" said doors are arranged to first move outwards and there-after laterally along the wall of the vehicle. The desired path of movement is obtained by means of guiding rails which are positioned near to the upper and lower edges of the door and a10ng which supporting members fixed to the door move. In winter conditions, however, the lower rails are easily frozen and cause functional disturbances which, especially in train cars and buses, constitute a serious disadvantage.
The object of the present invention is to provide a new sliding door which is suspectiblè to disturbances caused by freezing.
The sliding door of the invention comprises a door, especially for trajn cars and buses, comprising a door panel having a guide member at its upper end, a first guiding rail extending along the side wall of the vehicle for guiding said guide member of the door panel, , 3fi a drive cylinder the piston rod of which is connected to the door panel through two first swinging arms and two second arms each linked with a respective first arm and with the door panel, one at the upper part and one at the lower part thereof, for exerting a pushing force on the door panel substantially per-pendicularly to its plane when the door is in closed position.
The door structure is characterized in that'in order to transfer said pushing movement to a sliding movement along the side wall of the vehicle the second arm acting on the upper part of door panel is provided with a fixed extension extending beyond the link with the respective first'arm and being guided in a second guiding rail provided in a plane at the upper end of the door panel, and in that in order to transfer the guided movement of the upper end of the door panel to the lower end thereof the second arms are interconnected with each other by means of a rigid rod extending along the door panel.
According to the invention, the guiding r,ails required in the sliding door are positioned only in the area of the upper edge of the door, inside the car, for which reason the sliding door functions realiably also in hard winter conditions and the door, when opened, is not pushed out more than is necessary for permitting a lateral movement. A swinging move-ment of the door is not permitted in trains due to the res-tricted space between the train car and the platform.
In one aspect of the present invention, there is provided a plug door installation within a vehicle side wall opening, especially for train cars and buses, comprising a door panel having a guide member at its upper end, a first guiding rail extending along the side wall of the vehicle for guiding the guide member of the door panel, a drive cylinder, the piston rod of which is connected to the door panel through two first swinging arms and two second swinging arms each lZ36 -2a-linked with a respective arm and with the door panel, onearm at an upper part and one at a lower part thereof, for exerting a pushing force on the door panel substantially per-pendicular to the plane of the door panel when such is in closed position, characterized in that in order to translate the pushing force to a sliding movement of the door panel along the side wall of the vehicle, the second arm acting on the upper part of the door panel is provided with a fixed extension extending beyond a link with the respective first arm and being guided by guide member in a second guiding rail located adjacent the upper end of the door panel and extending generally in a common plane with the side wall, and in that in order to provide coordinated movement of the upper end of the door panel to the lower end thereof, the second arms are connected with each other by means of a rigid rod extending along the door panel.
The invention is illustrated by way of example in the accompanying drawings wherein, ~
Figures lA and lB are top views of a sliding door according to the invention, in closed and open position, and Figure 2 is a side view of the sliding door in the plane of the door.
In the drawing, a door panel is designated by numeral 1. Adjacent to its upper edge extends a guiding rail or groove 2 along which a support member which is secured to the front edge (from which the door opens) of the upper part of the door and comprises an arm 3 and a roll 4 or similar moves, while guiding the upper edge of the ,, " 11~123~
door to move in the required manner. The drive means for the door comprises a drive cylinder 5 which operates, for example, pneuma-tically. The piston rod 6 of the cylinder 5 is linked to an arm 7 Which~atcneof its ends, is fixedly connected to a vertical connec-ting rod 8. To the upper and lower ends of the connecting rod 8 are fixedly connected arms 9 and 9' which by means of links ll and ll' are connected to arms lO and lO' which again are connected to the door l by means of bearings or links 12 and 12'. The arms lO and lO' are interconnected with each other by means of a vertical rod 13 which preferably is formed in one piece with the arms 10 and 10'. The upper arm lO extends beyond the link 11 as a fixed extension arm 14 at the end whereof a roll 15 or similar is arranged to move in a guiding rail or groove 16. Numeral 17 designates the outer wall of the vehicle.
When the piston rod 6 is pushed out, the arms 7 and 9 and 9' turn with the rod 8, while the arms lO and lO' push the door l outward.
The rail 4 guides via the supporting member 3,4 the front edge of the door into the desired movement, while the movement of the rest of the door l is guided by the rail 16 through the roll 15 or similar which moves therein and is arranged at the end of the fixed extension 14 of the arm lO so as to prevent any part of the door l from being unnecessarily pushed out of the wall 17 of the vehicle.
An essential feature in the invention is that the guiding rail in the lower edge of the door that hitherto has been used for pro-ducing the opening and closing movement of the door is replaced by the construction of link arms 9,11,10,12,13,14. While a preferred embodiment is shown in the drawing, the desired result can also be achieved by means of various modifications. The arms 10 and 10' need not engage the door 1 at the centre thereof, and the guiding 2,3,4 can, instead of the front edge, guide another part of the door, for example, the rear edge. The rod need not be pivotal but the arm 7 could be rigidly connected to the arms 9 and 9' while turning around the rod 8, in which case this could be replaced by pins located at the bottom and the top. The extension arm 14 need not be of the shape described. The shapes of the guiding rails 4 and 6 are, more-over, quite roughly illustrated in the drawing. It could further be contemplated to omit the rod 13 and l.et the door panel l transfer the guided movement of the upper part to the lower part of the door. In order to achieve necessary rigidity of the structure this would, however, require substantially more elaborate bearings at 12 and 12' as well as thicker arms 10 and lO', or toothed connec-tions between the arms lO,lO' and the door l.
