Definitions

  • the present invention relates to a magnetically operating locking and control device.
  • control devices of this type which employ rocking magnets, the difficulty is encountered to move the blocking and control elements proper from one end position to the other end position and vice versa. This difficulty is due to the fact that an intennediate position of the anchor ing elements for the end positions cannot be realized or only with a considerable number of elements.
  • an object of the present invention to provide a magnetically operating blocking and control device which can satisfactorily be moved from one end.
  • FIG. 1 illustrates a permanent magnetically controlled blocking device in one end position.
  • FIG. 2 shows the blocking device of FIG. 1 with the blocking anchor occupying its intermediate position.
  • FIG. 3 illustrates the blocking device of FIGS. 1 and 2 shortly prior to reaching its other end position.
  • FIG. 4 is a modification of a permanent magnetically controlled blocking device according to the invention in one end position.
  • FIG. 5 shows the design of FIG. 4 in its other end position.
  • the magnetically operating blocking and control device is characterized primarily in that at least two canier elements are provided for permanent magnets, which carrier elements are selectively connected to each other while one of said carrier elements forms a rocker with at least one blocking anchor whereas the other carrier element together with the rocker carrier element is adapted selectively to be moved in a positive guiding means against a force, preferably a spring force, the permanent magnets arranged or introduced on both sides of the common central plane symmetrically in or on the carrier elements having their poles so located that the pole sequence in the rocker carrier element corresponds to the pole sequence in the other carrier element.
  • the positively guided carrier element there is provided at least one unilaterally open chamber in which at least one permanent magnet may be moved back and forth.
  • the stopping of the individual control or blocking elements in the so-called end position is, in conformity with the present invention, effected through the intervention of blocking anchors in such a way that with an uneven number of the permanent magnets either one or the other end position is blocked, whereas with an even number of the permanent magnets the blocking anchor is through the intervention of the rocker carrier element pivotable into a position in which the carrier elements are movable opposite to or in the direction of the force which acts in the direction of the positive guiding means.
  • the positive guiding means for one carrier element may be in the form of a housing which surrounds said carrier element and the rocker carrier element as well as a helical spring.
  • the housing is, in conformity with the invention, at one side provided with a passage or opening for the blocking anchor while the blocking anchor, when occupying one end position, engages against a force, preferably a spring force, the marginal portions of the housing which are entirely or partly in a collar-like manner bent outwardly.
  • a further embodiment of the invention which is characterized in that in a selectively closed or open housing there are provided at least two permanent magnets of which one magnet is selectively fixedly connected to the housing whereas the other magnet is movable in the housing by means of a further permanent magnet which is adapted from outside of the housing to be introduced into an auxiliary housing or housing chamber.
  • the first mentioned main housing may, in conformity with the invention, have a recess into which there may be introduced a blocking or control member.
  • the housing I fonning the positive guiding means is adapted to receive therein a carrier element 2 which is movable in the housing against a helical spring 3.
  • a carrier element 6 Rotatably mounted on the carrier element 2 is a carrier element 6 which forms a rocker and has magnets 7 and 8 inserted therein.
  • a spring magnet 10 Connected to the carrier element 6 is a blocking anchor 4 which, when occupying its rest position shown in FIG. 1, books over the marginal portions 13 which at the opening of the housing 1 are bent outwardly.
  • Spring 3 holds the anchor in this hooked position.
  • the induction rod 12 with the magnet 9 (FIG. 2) is introduced into the chamber 11, the magnet 7 inserted in the carrier element 6 is repelled to such an extent as the magnets 8 and 10 will permit. If all magnets 7, 8, 9 and 10 are of the same polarity and also have the same magnetic field intensity, the carrier element 6 will move into the position of FIG. 2 which may also be termed the balance or intermediate position. The forces exerted by the magnet 9 upon the magnet 7 and by the magnet 10 upon the magnet 8 will then be balanced. In order to obtain this balance position of FIG.
  • This embodiment of the invention illustrates the possibility in the variation of the construction with magnets if for the respective function magnets of the same character are employed which make it possible to obtain the FIG. 2 or balance position.
  • the magnets may have a plurality of poles and that the slightest displacement of these poles makes possible an intermediate position of the blocking anchor.
  • the magnetic force will always be greatest where all poles (north, south) are located opposite to each other.
  • the magnets always located opposite to each other are the magnet 8 in the carrier element 6 and the magnet 10 in the carrier element 2.
  • the force exerted by the magnets 8 and 10 upon each other can be balanced only by the force exerted by the magnet 7 in carrier element 6 and the magnet 9 inserted in the induction rod 12, provided that both groups of magnets correspond to each other with respect to their polarity. It will be evident that a plurality of embodiments for the magnetic induction rod is possible.
  • this embodiment comprises a housing 14 with two permanent magnets 15 and 16 which, due to the fact that they have the same polarity, repell each other and consequently are pressed against the walls of the housing.
  • the pushrod 17 of an imaginary control cannot enter the recess 18 in housing 14 because the magnet 16 blocks the path.
  • a magnetically operable blocking and control device which includes: first carrier means reciprocable from a first position to a second position and vice versa, guiding means reciprocably guiding said first carrier means, second carrier means pivotally supported by said first carrier means and adapted to be pivoted relative to said first carrier means between a blocking position and an unblocking position, said second carrier means including a latching member, locking means operable to lock said latching member when said first carrier means is in said second position and said second carrier means is in said blocking position, first and second permanent magnet means carried by said second carrier means and respectively arranged on opposite sides of and symmetrically with regard to the pivot axis of said first carrier means, third permanent magnet means carried by said first carrier means and arranged opposite said second permanent magnet means, fourth permanent magnet means selectively reciprocable in said first carrier means opposite said first pennanent magnet means, said third and fourth permanent magnet means having the same field intensity as the respective oppositely located second and first permanent magnet means and having such a polarity with regard to the polarity of said second and first permanent magnet means as to hold said
  • said guiding means includes housing means having a bottom at one end and being open at the opposite end and slidingly engaging said first carrier means, and in which said spring means includes a helical preloaded pressure spring having one end resting against said bottom and having its opposite end resting against said first carrier means.
  • a device in which said first carrier means has a chamber opposite and closed toward said first permanent magnet means and being open in opposite direction and in which said fourth permanent magnet means is selectively movable into and out of said chamber.
  • said second carrier means includes a rocker having two arms arranged on opposite sides of the pivot axis of said rocker with said first and second permanent magnet means respectively connected to said arms
  • said latching member includes an anchor member fixedly connected to said rocker and operable when said fourth permanent magnet means is withdrawn from said first carrier means to be moved by the action of said second and third permanent magnet means into locking engagement with said locking means
  • a device in which the bottom of said housing means is provided with a passage for permitting said latching means to pass therethrough while said fourth pennanent magnet means has been received by said first carrier means and magnetically acts upon said first permanent magnet means and while said second and third permanent magnet means magnetically act upon each other.
  • a device in which the housing portion directly defining said passage includes a flanged portion forming said locking means.
  • a magnetically operable blocking and control device which includes: housing means, first permanent magnet means arranged in said housing means, second permanent magnet means arranged in said housing permanent magnet means arranged in said housing means and having at least a portion selectively movable toward and away from said first permanent magnet means, and third permanent magnet means movable selectively into and out of the magnetic field of said second permanent magnet means for controlling the same, said first and second permanent magnet means being of the same polarity with the poles of the same polarity facing each other, and said housing means including first chamber means having said first and second permanent magnet means arranged therein in spaced relationship to each other and selectively so that said second permanent magnet means is outside the magnetic field of said first magnetic means, said housing means also including second chamber means adapted selectively to receive said third permanent magnet means, said third permanent magnet means being movable in said second chamber means selectively into and out of the magnetic field of said said second permanent magnet means to thereby control the position of said second permanent magnet means.
