Definitions

  • Doors whatever applications they are intended for, are normally mounted on hinges so as to allow their pivoting round a vertical axis.
  • Different types of spring operated devices have been produced for returning said doors into a closed or open position.
  • tumbler switches as applicable for the control of electric circuits, said switch systems including a lever pivotally secured to a spindle and controlled by a compression, tractional or the like spring the stationary bearing point of which and the bearing point of which on the pivoting lever are arranged in a manner such that starting from a medial position of unstable equilibrium the lever is urged back by said spring in either direction until one of two stable positions against a corresponding stop is reached.
  • this tumbler system In known spring-urged devices used for returning doors into normal position, this tumbler system is stationary and its lever controls the door directly or through the agency of pivoting links.
  • the suitable medial position of the lever of the tumbler corresponds to a door opening at about 45.
  • the tumbler system carries the door along either towards its closed position or towards an open position at about 90 of its closed position.
  • any fortuitous stress that urges the door further open than is allowed by thearrangement and the associated links leads to a deformation of the latter that serve as stops for the opening of the door and can only be of reduced size and housed near the pivotal axis of the door for reasons of bulk and aesthetic appearance.
  • Our invention has for its object to remove such drawbacks in a very simple, elegant and economical manner.
  • the (Cl. Iii- 79) door or the like pivoting element includes a member cooperating with a corresponding part forming part 01' the actual tumbler, the action of said parts on one another being an intermittent one and the points at which the common action of these members begins and finishes are defined through a pivoting angle of the door or similar element with reference to the stationary element to which it is pivotally secured.
  • the door or the like member is connected with the tumbler system no longer throughout the angular stroke allowed for its operation as a door but only for a predetermined angular stroke that is the sum of a first angle which may be termed the spring closing angle during which the tumbler lever starting from its unstable medial position drives the door up to its position of closure and holds it against its stop and of a second angle or cocking angle during which the tumbler lever moving in the opposite direction starting from its medial unstable position drives the door until said'lever abuts in its turn against a stop corresponding to its cocked position, the door being then entirely released beyond said cocking point with reference to the tumbler device during the remainder of its possible movements allowed for its operation as a door.
  • a first angle which may be termed the spring closing angle during which the tumbler lever starting from its unstable medial position drives the door up to its position of closure and holds it against its stop and of a second angle or cocking angle during which the tumbler lever moving in the opposite direction starting from its medial unstable position drives the door
  • connection between the lever of the tumbler and the door is provided through a first mechanical member such as a cylindrical projection, a roller, a suitable cam, gear teeth or the like carried on the tumbler lever or on the door and meshing preferably without any play, for the system of two operative angles of rotation of the door disclosed in the preceding paragraph, with a second member forming a suitable counterpart for the former and carried on the opposite part, that is on the door or on the lever of the tumbler, according to the case, the mutual drive of the door through the lever and of the lever through the door being provided through a sliding contact between the two abovementioned mechanical members, the arrangement of said members being such that the engagement is at an end when the tumbler lever rests on the cocking stop and the door thus released continues its opening movement beyond the cocking point.
  • a first mechanical member such as a cylindrical projection, a roller, a suitable cam, gear teeth or the like carried on the tumbler lever or on the door and meshing preferably without any play, for the system of two operative angles of rotation of
  • connection between the tumbler lever and the door is provided through the engagement between two toothed sectors that provide a better continuity of the mutual driving engagement between the lever and the door during their travel through the two above mentioned operative angles.
  • Fig. 1 illustrates .by way of example a door controlled by a tumbler system with a compression spring, the connection being performed through interengaging toothed sectors.
  • Fig. 2 is a diagrammatic view of a modified tumbler system with a tractionalspring.
  • Fig. 3 illustrates a connection through a forked tumbler lever engaging a roller carried on the door.
  • Fig. 4 shows reversely the forked lever mounted on the door and a cylindrical projection secured to the tumbler lever.
  • the pivoting door is hinged round the axis XX which may be a pintle rigid for instance with a piece of furniture I through the agency of a hinge 2 secured to the side '3 of said piece of furniture that is illustrated as stationary.
  • toothedsector d having for its axis the vertical projection of the axis XX.
  • a tumbler system 5 including a tumbler lever B pivoting round a spindle I mountedin the casing I2 which will be presently described.
  • a link 9 surrounded by a compression spring I bearing at II against the casing I2 of the tumbler system 5.
  • the lever B is illustrated initsoperative cocked position for which it abuts against the stop. .13.
  • the pivot 8a on the lever enters the position 13b for the unstable medial position of the tumbler system and the position .80 for the .closedposition of the door.
  • a toothed sector I4 having as a center the pivot point 1 and meshing .with the toothed sector 4 rigid with the door.
  • Fig. 1 different positions of an arrow passing through the axis X-X, parallel with the plane of the door and carried along by it in its movements.
  • the door I5 being pivotally secured to the piece of furniture over a projecting ledge thereof may be completely folded over the outer side of the piece of furniture as shown in dot and dash lines at I6, that is for a complete opening through 2'70.
  • .the arrow moves with the door out .ofthe position I'fid when the door is being closed, and there is no connection with the tumbler system :during such a rockingmovement until the arrow reaches the angular position Ilia.
  • Fig. 2 shows a modification of the tumbler device including a'tractional spring engaging the stationary point IIa, the said pivotal connection being locatedin this case beyond the pivoting point I with reference to II, (Fig. .1') .in order to obtain an unstable position at 8b on the line II--'I and cocked .positionsyat .8a and 8c corresponding to the engagement of door I 5 with stop 29 andlever 6 with stop I3 respectively.
  • Fig. .3 shows by way of example a further modification, in which a roller 22 is mounted on a spindle 23 rigid with the door 15. This spindle is mounted on 'a suitable support secured to the door.
  • the lever 6 showsat its end facing the door a fork with a recess .24 cooperating with the roller 22.
  • the lever and the door are illustrated in solid lines in the position corresponding to the solid lines of .Fig. 1 at the moment at which the roller begins to engage or. to disengage the fork.
  • the arm 25 of this fork is shaped so as to allow the release of "the door for an opening thereof through a larger angle.
  • the lever B is illustrated in dot and dash lines for the position of the :door in its closed position.
  • Fig. 4 illustrates the opposite modification for which the fork 6 is carried by the door through the intermediary of ,a suitable support 66 and the roller by the lever.
  • a tumbler system including a-pivot on the member to be closed by the door parallel to the pivoting axis of the door.
  • a lever pivotally carried by said pivot spring means associated with said lever for urging said lever away from a neutral position of alignment to either side thereof, a stop for engaging and thereby limiting the movement of the lever beyond a predetermined point on one side of the neutral position, a stop arresting the movement of the door in its closed position and consequently of the lever for a predetermined position of said lever on the side of its neutral position opposed to the first mentioned stop and interengaging means on the door and lever, through which the angular movement of the door between predetermined limits corresponding to the stops provides for the rocking of the lever to either side of its neutral position, the action of the interengaging members on one another ceasing when the lever meets the first mentioned stop.
