  • Biasing means permanently urges the slide to its rest position.
  • a fixedly positioned turnably mounted shaft has an inner portion extending through the aperture in the slide and an outer portion which projects from the housing for connection to a door so that the shaft will turn as the door moves between open and closed positions.
  • Connecting means connects the shaft with the slide so that the latter is moved from its rest position when the shaft turns.
  • a roller ring is mounted on the inner portion of the shaft and received in the aperture in rolling engagement with the edge faces so as to guide and support the shaft in the aperture with minimum friction.
  • the present invention relates generally to a device for closing doors and the like, and more particularly to such a device wherein a slide is movable longitudinally within a housing, being urged to a rest position by biasing means, and being moved from its rest position in response to turning movement of a shaft With which it is associated and which in turn is connected with the door or other element which is to be closed by the device.
  • the slide element arranged within the housing is provided with a slot extending in the direction of movement, and a portion of the shaft extends through the slot transversely of the direction of movement, being provided with a cam track which cooperates with abutments provided on the slide element, usually carrying suitable rollers, so as to urge the slide element from rest position to operative position in response to turning movement of the shaft which in turn is occasioned by movement of the door or analogous element between its open and closed positions.
  • abutments provided on the slide element, usually carrying suitable rollers
  • An additional object of the present invention is to provide such a device which is relatively simple in its construction and requires less space than heretofore necessary.
  • a device for closing doors and the like which comprises elongated housing means and slide means arranged in this housing means longitudinally slidable in predetermined direction between a rest position and a working position.

  • a roller ring is mounted on the inner portion of the shaft means and is received in the aperture in rolling engagement with the edge faces for guiding and supporting the shaft in the aperture With minimum friction.
  • anti-friction bearing means such as a needle bearing is used to mount the roller ring on the inner portion of the shaft, whereby again frictional forces are reduced and the operating efficiency of the device improved, while at the same time slippage of the roller ring With respect to the slide means is reli-V ably prevented.
  • a needle bearing is advantageous because it permits the dimensions of the device to be kept small.
  • the slide means has two parallel walls or substantially parallel walls, each provided with one of the aforementioned apertures which are then in transverse alignment, one or both of the apertures may accommodate one of the roller rings.
  • the roller ring may be provided with an annular shoulder which engages the slide means in the region of the aforementioned aperture, but outwardly and laterally thereof.
  • FIG. 1 is a top-plan view of an embodiment of a device according to the present invent-ion, partly sectioned and partly broken away with removable portions of the housing having been omitted for the sake of clarity;
  • FIG. 2 is a section taken on the line II-II of FIG. 1.
  • the illustrated device is her shown as a door closer and may for instance be mounted in the tubular frame of a door structure.
  • the device comprises a drive section and a cylindrical section 11, together constituting a housing.
  • the sections 10 and 11, or the housing sections 10 and 11 as they will be called hereinafter, are connected releasably via the screws 12.
  • a connecting portion 13 is prov-ided on that end of the housing section 11 which faces the housing section 10.
  • a shaft 16 Arranged in the housing section 10 is a shaft 16 which is mounted turnable via the anti-friction bearings 14 and 15.
  • the shaft 16, or rather the portion thereof which projects outwardly from the housing section 10 may be coupled with a door so as to turn about its longitudinal axis in response to movement of the door between open and closed positions thereof.
  • a mounting ring 18 is connected with the removable cover portion 17 of the housing section 10, and in turn engages and holds in position the anti-friction bearing 14.
  • the anti-friction bearing 15, on the other hand, is accommodated in a recess of the wall bounding the housing section 10, as is particularly clearly shown in FIG. 2.
  • a sealing gasket 19 Interposed between the anti-friction bearing 15 and the aperture through which the shaft 16 penetrates the wall of the housing section 10, is a sealing gasket 19, visible in FIG. 2. Also visible in FIG. 2 is the cam portion 20 which is xedly mounted on the inner portion of the shaft 16, and which is also visible in FIG. l.
  • a slide means or carriage is constituted by two plate sections 21 extending in parallelism with one another transversely spaced, as shown in FIG. 2.
  • the members 21 are each provided with a longitudinally extending slot or aperture 23 (compare FIGS. 1 and 2) and the cam portion 20 is located between and turnable with reference to the plate members 21.
  • Rollers 22 are turnably mounted intermediate the plate members 21 on antifriction bearings and cooperate in known manner with the cam portion 20 for transmitting motion between the latter and the slide means composed of the plate members 21.
  • the inner portion of the shaft 1.6 extends through the two aligned apertures 23.
  • a roller ring 24 is mounted via a needle bearing 26 on a portion 27 of the shaft 16, for turning movement with respect to the shaft 16, and the roller ring 24 extends into the aperture 23 of one of the plate members 21 (see FIG. 2). Further, the roller ring 24 is provided with an annular shoulder which abuts the major face of the plate member 21 into whose aperture 23 the roller ring 24 extends, as shown in FIG. 2.
  • a portion 28 of the shaft 16 is received with play in the aperture 23 of the other one of the plate members 21.
  • the housing section 11 defines a substantially cylindrical inner space and accommodates a coupling rod 30 in this space, which is releasably connected via screws 29 with the slide means constituted by the plate members 21, as clearly shown in FIG. 2.
  • a piston member 32 provided with a conventional valve-arrangement, and the free end of the coupling rod 30 is coupled with the piston member 32 via a pin 31 in the manner clearly visible in FIG. 2.
  • a helical expansion spring surrounds the coupling rod 30 within the contines of the housing section 11 and abuts with one end against the piston member 32 and with the other end against an adjustable abutment 34.
  • the cylinder and piston arrangement thus constituted, in conjunction with controllable iiow channels provided in the housing section 11, constitutes a damping device or shock absorber.
  • the manner in which the control channels are regulated is of no importance for the present invention, and therefore not shown in detail.
  • the adjustable abutment 34 is connected to the end portions of parallel tension rods 35 which are thereby connected with one another in transverse relationship.
  • the opposite free ends of these tension rods 35 are connected by a bridging member 36 which is provided with a central bore into which a screw 37 is threaded so that, by threading the screw 37 to a greater or lesser extent through the bore in the member 36, the pretensioning of the spring 33 may be adjusted by adjusting the abutment 34 via the intermediary of the tension rod 35.
  • the device is illustrated in FIGS. l and 2 in its rest position, that is in the position which it would assume if a door connected with the shaft 16 is closed. Assuming that the door is a swinging door, the device would move from the illustrated rest position to one of two (operative positions, depending upon the direction in which the door swings. In any case, when the door would be thus moved from closed to an open position, the cam portion 20 would move in response to turning of the shaft 16, and such motion would be transmitted to the slide means via a respective one of the rollers 22. This would cause movement of the slide means composed of the plate members 21 towards the left in the drawing, with conmitant tension of the spring 33 through the intermediary of the cupling rod 30 and the piston member 32.
  • the spring 33 may be differently constructed, or replaced with other means for this purpose, and in fact the entire shock absorbing arrangement in the housing section 11 may be constructed differently from what has been shown. It will also be appreciated that the other of the apertures 23 may be associated with a roller similar to the roller ring 24 which has been shown.
