  • the present invention relates generally to an arrangement for closing doors and the like, and more particularly to a novel arrangement of this type.
  • one feature of the invention resides in an arrangement of the type under discussion which, briefly stated, comprises a frame having a transversely extending upper frame member and a door swingably mounted in this frame and having an upper part adjacent the frame member.
  • a door-closing unit is accommodated in the frame member and has a shaft projecting downwardly towards the upper part of the door and which is permanently biased for turning movement towards a rest position.
  • coupling means which couples the shaft with the door so that the shaft is turned from its rest position in response to swing of the door.
  • This coupling means comprises a coupling member which extends along the upper part of the door and which has two portions at opposite axial sides of the shaft. A pair of screws are each connected with both of these portions and draw the same together in a sense clamping the shaft between these portions against rotation relative to the door.
  • at least one bushing which surrounds at least one of the screws and which has axially spaced sections received in respective recesses provided in the aforementioned portions of the coupling member.
  • the screws are reliably relieved of any forces which act in parallelism with the line of separation between the portions.
  • the space required for the provision of the bushing is very small but the latter, despite its small dimensions, is capable of reliably withstanding any forces which act in the direction of the line of separation of the portions. This eliminates the transmission of such forces to the screws and the possibility of damaging of the latter. It further eliminates the possibility of undesired loosening of the screws in operation.
  • resort to the present invention makes it possible to have relatively wide manufacturing tolerances in the manufacturing of the various components but because a relatively wide line of separation may be permitted to exist when one or more of the bushings are present for reasons which will become clearer subsequently.
  • FIG. 1 is a partially sectioned partially broken away vertical elevation of an arrangement embodying the invention
  • FIG. 2 is a top-plan view of FIG. 1 with certain portions omitted for clarity; a
  • FIG. 3 is a fragmentarysectional view, on an enlarged scale, showing a detail of the embodiment in FIGS. 1 and 2;
  • FIG. 4 is a partially sectioned, partially broken away detail view of FIG. 3, on a still further enlarged scale and in an exploded view.
  • an automatically operated doorclosing unit 15 Accommodated in the upper transversely extending frame member 11 is an automatically operated doorclosing unit 15 of known conventional construction which is provided with a shaft 16 extending downwardly towards the door, that is downwardly out of the frame member 11.
  • the shaft 16 constitutes the upper pin about which the door is swingably mounted in the frame, and at its lower end the door is mounted in the frame, or more particularly in the transversely extending lower frame member 12, in conventional manner by means of a pin-type journal 17 as illustrated.
  • the shaft 16 of the door-closing unit 15 is connected with the upper part 13 of the door with a coupling 18 according to the present invention.
  • the coupling 18 comprises an elongated member 19 which is mounted between the ledges 14 with limited longitudinal displacement capability, and which is preferably also pivotably mounted.
  • a carrier plate 20 which is associated with and located beneath the member 19 and provided at that end which is the righthand end in FIGS. 1 and 2, with upwardly extending lugs 21 with which adjustment screws 22 are provided in the member 19 cooperate for abutment purposes.
  • the point of abutment can be varied so that the member 19 can pivot about the pivot mount 27 to a greater or lesser degree depending upon the extent to which the screws 22 are threaded into its free end portion.
  • the plate 20 is connected with the part 13 of the door in suitable manner so as to be non-movable, for instance by means of screws as illustrated in FIG. 1.
  • the member 19 rises in its cross-sectional height towards the left-hand side of FIGS. 1 and 2, until it reaches approximately the height of the space between the ledges l4 (compare FIG. 1). It then continues inform of a tongue 23 which has a much lesser height as also evident from FIG. 1, corresponding approximately to that of a supporting member which is constructed as a pin 24 and projects upwardly from the plate 20.
  • the pin 24 is of circular cross-section in the illustrated embodiment and a pressure screw 25 is threaded into it so as to be adjustable in the direction of the width of the door, that is longitudinally of the part 13 thereof.
  • Pin 24 in turn is located in a bifurcated portion of the tongue 23, formed by the presence of a slot 26 and the free end of the pressure screw 25 abuts against the base of this slot so that, by threading the screw 25 into and through the pin 24 to a greater or lesser degree, the position of the door can be adjusted with reference to the shaft 16 by transmitting requisite force upon the member 20.
  • the shaft 16 has a polygonal cross-section for instance rectangular as shownand extends into a vertical recess of the member 19, which recess is to be closed by a bridging member 28 with the help of tensioning screws 29 so that the shaft 16 can be tightly clamped against rotation with reference to the plate 20 and therefore to the door.
  • the bridging member 28 may abut against the upper surface of the tongue 23 if desired.
  • the bushings may be provided with a bevel (compare FIG. 4).
  • the bores 32 in the member 28 are enlarged at 33, and similarly the bores in the member 19 are enlarged at 34, and the total axial length of the bores is such that it is slightly greater than the axial length of the bushings 30.
  • the inner diameter of the bushings 30 corresponds to the outer diameter of the screws 29.
  • An arrangement of the character described comprising a frame having a transversely extending upper frame member; a door swingably mounted in said frame and having an upper part adjacent said frame member; a door-closing unit accommodated in said frame member and having a shaft projecting downwardly towards said upper part and which is permanently biased for turning movement towards a rest position; and coupling means for releasably coupling said shaft with said door so that said shaft is turned from said rest position in response to swinging of said door, said coupling means comprising a coupling member extending along said upper part of said door and having two portions located at opposite axial sides of said shaft and defining with one another an unobstructed gap, two pairs of axially aligned cylindrical bores provided in the respective portions, at least one cylindrical bushing bridging said gap and having axially spaced sections each received in a bore of one pair of said bores, and a pair of screws each extending through the aligned bores of one of said pairs and being connected with both of said portions, (also bridging said
  • said coupling means comprising an additional bushing surrounding the other of said screws also bridging said gap and having axially spaced sections which are received in the respective bores of the other pair of bores.
