Definitions

  • the invention relates to a swingable sliding door for cars, especially passenger cars and more particularly to a swingable sliding car dor which is held in vertical position by two rigidly joined support bars hingedly secured on the door frame of the car body in vertically spaced and mutually parallel relationship.
  • the free ends of the support bars are slidably guided in guide tracks on the inside of the door, which is further guided by a guide arm extending from a side edge of the door and linked to a carrier guided on a guide track provided on the car body, generally near the door opening thereof.
  • the door after having been swung by means of a pivotally secured arm into the swung-out position, slides along the guide bar.
  • One end of the guide bar is simultaneously moved along with the slide in the guide track mounted below the lower edge of the door.
  • a door assembly of the kind disclosed in the aforesaid British patent has the disadvantage that due to unfavorable directions of force and an unfavorable distribution of the load, a convenient slamming of the dooras is possible with hinged doors and as is also desirable for sliding doors-is not possible. Moreover, the door is not safely guided at all points, particularly when the door is in the swung-out position; as a result, the door cannot sustain additional loads as may be caused, for instance, by a person leaning on the open door.
  • Another more specific object of the invention is to provide a novel and improved swingable sliding door, the entire guiding and supporting mechanism of which is concealed except for a narrow slot per door so that the outer 3,484,993 Patented Dec. 23, 1969 appearance of the car body is not adversely affected to any appreciable extent.
  • the support roll that is, the roll which rotates about a horizontal axis, has advantageously a somewhat outwardly curved peripheral surface so that it can perform a corresponding turning movement with reference to its rotational axis, as is necessary or at least desirable at the beginning of the swinging out movement of the door.
  • An arrangement as just described assures smooth movements of the guide arms and of the associated rollers within the guide track and such smooth movements of all components with reference to each other is obtained with a minimum of structural components. Moreover, the arrangement also makes possible an easy slamming of the door.
  • a support arm is rigidly secured to the edge of the door opposite to the one referred to in the next preceding: paragraph.
  • the support arm mounts a support roll rotatable about a horizontal axis and above the support roll a guide roll rotatable about a vertical axis. Both rolls are guided within a track disposed in an outside wall of the car body below the sill of the door frame.
  • the upper part of this hori zontal track is lengthwise covered by a cover strip preferably substantially flush with the outside wall of the car body for locking the guide roll and with it the support bar in the guide track.
  • Support of the door against lateral tilting is effected by support bars pivotally secured to the door frame.
  • Each support arm mounts on its free ends a roll rotatable about a vertical axis and guided on a branch of a track of U-shaped cross-section provided on the inside wall of the door, preferably flush with the same.
  • a second guide roll is provided on the guide arm next to the guide roller rotating about a vertical axis.
  • the second guide roll enters in a curved track section at the end of the guide track just before the door reaches its closed position.
  • FIG. 1 is an elevational inside view, partly in section, of a swingable sliding car door assembly according to the invention
  • FIG. 2 is a plan view, partly in section, of FIG. 1;
  • FIG. 3 is a righthand side view, partly in section, of FIG. 1;
  • FIG. 4 is a plan view, partly in section, of the door in its closed position.
  • FIG. 5 is a sectional plan view similar to FIG. 4, but showing the door in an intermediate position such as a partly opened position.
  • a two-arm link 3 is linked with one arm 3b to a lining 4a of vertical door edge 1, at about the mid-point of the door lining which is cortinued by a lip 4b.
  • the angle of link 3 is such that in the closed position of the door, arm 3a is substantially flush with the outer wall of a car body 25 and arm 312 extends into the door opening, as best shown in FIG. 4.
  • Arm 3a of link 3 mounts a support roll 5 rotatable above a horizontal axis and a guide roll 6 rotatable about a vertical axis is mounted above the support roll. Both rolls 5 and 6 are guided in a guide track 7 formed in the outside wall of car body 25.
  • This track is partly covered along its length by a strip 8, preferably substantially flush with the outer surface of the car body.
  • the strip defines a narrow slot 9 through which arm 3a of bell crank arm 3 extends into track 7.
  • counter roll 6 abuts preferably against strip 8 thereby preventing arm 3a and support roll 5 from leaving track 7.
  • Roll 5 has preferably a slightly outwardly curved peripheral surface, thereby assuring a smooth movement of the roller within the track.
  • a support arm 10 is rigidly mounted. The free end of this arm has mounted thereon a support roll 11 rotatable about a horizontal axis and a guide roll 12 rotatable about a vertical axis. Both rolls 11 and 12 are displaceable in a track 13 continued by a curved track portion 13a for guiding the door inwardly and into the door opening.
  • Track 13 is also partly lengthwise covered by a strip 14 secured to a wall portion of the car body substantially flush therewith. As can best be seen in FIG. 3, the strip retains rolls 12 and 11 in track 13.
  • guide arm 3 mounts, in addition to guide roll 6, a guide roll 15, also displaceable in track 7. Just before the door reaches its closed position, roll 15 enters a hook portion 16 contiguous of track 7 and facing backwardly in the direction of movement of the door toward its closed position. As is evident, movement of roll 15 into hook portion 16 forces the door fully into its closed position.
  • the door is further supported by support arm 10 and link 3 mounting rolls 6 and 11, which as previously described, slides in similar arranged guide tracks 7 and 13, respectively.
  • Tilting of the door out of its normal perpendicular plane is prevented by support bars 17 pivotal on and rigidly joined on one end by a shaft 17a in vertically spaced apart and mutually parallel relationship.
  • the other end of each bar 17 mounts a roll 18 rotatable about a vertical axis and slidable in a guide track 19 formed in the inner inside wall of the door. Both rolls 13 are retained in track 19 by a strip 20 partly lengthwise overlying track 19.
  • FIG. 4 shows clearly that arm 3a of each door link 3 is substantially flush with the outside wall of car body and that arm 3b is located between the door edge 1 and the Wall of car body 25 so that each link is invisible for all practical purposes.
  • a swingable sliding door assembly when closed according to the invention presents substantially the same appearance as a hinged door, except for the narrow slot 21 (defined by strip 14) and slot 9 (defined by strip 8).
  • the invention provides a novel and improved swingable sliding car door assembly which can be opened and closed with very little effort and requires merely two slots on the outside of the car. As these slots are very narrow due to the provision of cover strips, they are very nearly invisible with respect to the outer appearance of the car body.
  • the tracks required on the door also do not materially affect the appearance of the inner wall of the door. Accordingly, the door of the invention may be used with highly styled passenger cars.
  • a swingable sliding door assembly for a car comprising in combination:
  • said door having in its inner side Wall a pair of horizontal elongate and vertically spaced first guide track grooves, the other end of each of said support bars extending into one of said track grooves positively and slidably retaining therein, said bars supporting the door in vertical position in any of its positions;
  • a support arm (10) fixedly secured on one end to the inside wall of the door adjacent to the lower corner of the front edge thereof, said car body having a second guide track groove in a wall below the bottom edge, said second guide track groove being engaged by the other end of said support arm and having a curvature such that the door is displaced between a door closing position substantially flush with the respective outside wall of the car body and a door opening position outwardly spaced from said outside Wall of the car body parallel thereto upon sliding of said other ends of the support arms along said second guide track groove;
  • each of said support bars pivotally supported on the car body mounts at its free end a guide roll rotatable about a vertical axis and slidable in the respective first guide track groove in the inside wall of the door, and wherein a cover strip is secured to said inside wall substantially flush therewith and partly overlying the first guide track groove therein, said cover strip retaining the guide roll positively in the track groove.
