Definitions

  • the present invention relates to automatic door-closing devices. More especially the invention is concerned with door-closing devices of the kind commonly referred to as floor springs.
  • the conventional floor spring comprises a unit to be mounted at floor level including a shaft to be coupled to the door so as to turn therewith as the door opens and closes.
  • An energy-accumulating spring is coupled to the shaft via a cam so that as the door is opened the cam turns to compress the spring. In the open position, the spring applies a force to the cam to restore it to its original position, so that when the door is released the cam turns the shaft to close the door once more.
  • Hydraulic damping means are also provided to cushion the closing movement of the door.
  • US-A-2752627 the origin of the features of the preamble of Claim 1 discloses a floor spring in which there are two cams coupled to the shaft, one for the energy-accumulating spring and the other for a hydraulic plunger of the damping means.
  • a follow-up spring relatively weak in comparison with the main spring, acts on the hydraulic plunger in order to keep its cam follower (roller) in contact with the respective cam.
  • a substantial opening force must be applied to the door.
  • oil is drawn into the corresponding cylinder from a surrounding reservoir through a non-return valve.
  • As the door closes and the plunger retracts oil is driven out from that cylinder through two separate orifices provided with respective adjustable needles, to select the rate of damped closing.
  • One aim of the present invention is to provide a device useable as a floor spring which is arranged so that, after any initial detent action on the door has been overcome, only a minimal force is required to move the door to its normal open position and compress the restoring spring.
  • a device will be of particular benefit to the elderly, handicapped or infirm who may have sufficient strength and mobility to "crack" the door a small initial angle but who would have difficulty in moving a door through its full opening angle against the resistance inherent in a conventional floor spring.
  • an automatic door-closing device comprises: a shaft to be coupled to a door so as to turn therewith as the door opens and closes; first cam means coupled to the shaft; first spring means coupled to the first cam means such as to be loaded thereby as the door is opened and to apply a force to the first cam means tending to restore the door to its closed position; second cam means coupled to the shaft; a piston coupled to the second cam means; and second spring means acting upon the piston such as to drive it in a first direction; closing movement of the door under the force of the first spring means acting through the second cam means to drive the piston in a second direction opposite to the first; characterised in that the strength of said second spring means and the form of the second cam means are so chosen such that during a substantial portion of the opening movement of the door the second spring means assists the opening of the door in opposition to the force of the first spring means; the piston causes fluid to flow through a circuit in opposite senses when it is driven in said first and second directions; and said circuit includes
  • the restoring spring unit 8 is more fully shown in Figures 2 and 3.
  • a coil spring 16 of high stiffness Within its casing 15 is housing a coil spring 16 of high stiffness.
  • One end of this spring engages an abutment plate 17 at one end of the casing 15, and the other end of the spring engages a second abutment plate (not shown) carried by the rod 7 so that the action of the spring is to urge the rod strongly to the right (as viewed in the Figures) to an extended position with respect to the casing.
  • the force with which the spring so acts is adjustable, and can be relieved eg for maintenance, by adjusting the axial position of the plate 17 in the casing 15 by means of four screws 18 threaded through the end of the casing and against which the plate 17 is thrust by the spring.
  • the illustrated unit also has a pivoted latch arm 19 to engage a side roller 20 on the rod 7 under an adjustable spring pressure 21, to provide a detent action against retracting movement of the rod.
  • a pin 36 held by the block 31 extends through one of the cross bores 34.
  • the lower limiting position of the jumper in the block is defined by the abutment of the pin 36 with the flat upper surface of the cross bore 34 within which it lies.
  • the upper limiting position of the jumper in the block is defined by the abutment of the tail of the jumper with the inner end wall 37 of the block.
  • FIG. 6 this shows the profile of the cam 4 which cooperates with the restoring spring unit 8. It is symmetrical about a central axis X to provide equivalent action in both opening directions of the door. Its central part is a depression 40 defining the closed position of the door. From here the profile rises quite steeply to positions approximately 12-15° either side of the axis and then rises gradually to positions slightly beyond 90° either side. Past the latter positions the profile is of constant radius.
  • the roller 9 is initially on the constant-radius portion of cam 5 and the door will therefore have a fast, undamped closing speed until the roller begins to rise up to the cusp 41.
  • the rod 13 is now pushed further back into the unit 14 to damp the final part of the closing movement of the door, the damping reaching a maximum as the roller 9 rises up the steepest part of the cusp 41, which corresponds to movement of the roller 6 into the depression 40 of cam 4, to ensure gentle closure.
  • the flutes 43 of the cam 5 are slightly overcut with respect to the splines (not shown) of the shaft 2 with which they engage, so that there is a small degree of lost angular motion between the shaft and cam.

  1. Automatische Türschließvorrichtung, beinhaltend: eine an die Türe gekoppelte Welle (2), welche sich mitdreht, wenn die Türe öffnet und schließt; erste, an die Welle (2) gekoppelte, Nockenmittel (4); erste Federmittel (16), welche so an die ersten Nockenmittel (4) gekoppelt sind, daß sie durch diese gespannt werden, wenn die Türe geöffnet wird und eine Kraft auf die ersten Nockenmittel (4) ausüben, welche dazu tendiert, die Türe in ihre geschlossene Stellung zurück-zubringen; zweite, an die Welle (2) gekoppelte, Nockenmittel (5); einen Kolben (24), gekoppelt an die zweiten Nockenmittel (5); und zweite Federmittel (25), welche so auf den Kolben (24) wirken, daß sie ihn in eine erste Richtung antreiben; eine Schließbewegung der Türe unter der Kraft des ersten Federmittels (16) wirkend durch das zweite Nockenmittel (5) so, daß der Kolben (24) in eine zweite, der ersten entgegengesetzte, Richtung getrieben wird; dadurch gekennzeichnet, daß die Stärke des zweiten Federmittels (25) und die Form des zweiten Nockenmittels (5) so gewählt sind, daß während eines wesentlichen Anteils der Öffnungsbewegung der Türe das zweite Federmittel (25) die Öffnung der Türe gegen die Kraft des ersten Federmittels (16) unterstützt; der Kolben (24) das Fließen einer Flüssigkeit durch einen Kreis (26) in verschiedene Richtungen bewirkt, wenn er in die genannte erste und zweite Richtung getrieben wird; und der genannte Kreis (26) Drosselmittel (27) enthält, welche auf die Flußrichtung durch den Kreis (26) ansprechen und welche so ausgelegt sind, daß sie wirksam sind, wenn der Kolben (24) in seine zweite Richtung getrieben wird (wenn die Tür schließt), aber unwirksam oder weniger wirksam sind, wenn der Kolben (24) in seine erste Richtung getrieben wird (wenn die Tür öffnet).
