Definitions

  • the invention relates to a locking catch for double doors with two door-side holding elements and two body-side locking elements, in which a spring accommodated in the catch housing presses the locking elements into the closed position and in which the holding element of one door is blocked in the closed position, even if the holding element of the other door is brought into the closed position.
  • a locking catch of the type mentioned is known that this locking function guaranteed.
  • the two locking elements are designed as slides, which are held in the catch housing in the closed positions by means of a compression spring.
  • the catch housing is attached to the body so that the direction of adjustment of the slide is parallel to the open front of the body.
  • the slides protrude from the catch housing with a triangular locking tip.
  • Holding elements are attached to the doors, which have a triangular snap-in receptacle. If a door is closed, the holding element adjusts the slide against the force of the spring until it can then snap into the latching receptacle of the holding element in the closed position of the door.
  • this known locking catch has the disadvantage that the closed doors do not fit snugly against the front edges of the body. Since the slide and the holding elements have a locking position defined in the closing direction, tolerances of the doors, the body and the attachment of the catch housing and the holding elements cannot be compensated for.
  • the holding elements are designed as retaining bolts which can be inserted in receiving slots of the Schnäppergephinuses that the locking elements than in the catch housing effectively pivotally mounted locking lever are formed, each extending into a receiving slot, that the locking lever during insertion of the mounting pin can be deflected out of these into the associated receiving slots, that the inserted retaining bolts are held resiliently in the end regions of the receiving slots by the pivoted-back locking levers and that a locking lever with a blocking projection is so in the end region of the receiving slot assigned to the other locking lever protrudes in that this locking lever is held in a non-pivotable manner by the retaining bolt inserted into this receiving slot.
  • the pivoting of the locking lever projecting into the receiving slots of the catch housing is achieved in a simple manner in that the retaining bolts are aligned with their central axes perpendicular to the longitudinal axes of the receiving slots and in that the receiving slots are horizontal and the retaining bolts are aligned vertically, and in that the locking levers on the insertion side of the Receiving slots are rotatably mounted between the receiving slots on a common bearing pin of the catch housing, the pivot axis being directed perpendicular to the longitudinal axes of the receiving slots. This creates enough space on the insertion side between the receiving slots that allows the locking levers to be pivoted in.
  • the locking lever is held by means of the spring on stops of the latch housing arranged outside the receiving slots.
  • a continuous deflection process for the locking levers when inserting and extending the retaining bolts into or out of the receiving slots is achieved in that the locking levers on the insertion side of the receiving slots are provided with deflection bevels, via which the locking levers in each case toward the other locking lever when the retaining bolt is inserted is pivotable and that the locking levers facing the end regions of the receiving slots are provided with bevels that form locking receptacles for the retaining bolts with the end regions of the receiving slots and hold them resiliently in these locking receptacles, and that these tightening bevels are inclined so that even when the retaining bolt is extended, the assigned locking lever is pivotable in the direction of the other locking lever.
  • the locking levers In order for the locking levers to be used for a locking catch attached to the lower edges and to the upper edges of the doors, a further development provides that the locking levers be designed symmetrically to a central plane running perpendicular to the pivot axis and therefore in two positions on the bearing journal which are reversed by 180 ° of the catch housing can be rotated. Simply by storing the locking lever, the blocking can therefore be shifted to one or the other receiving slot, as is required for double doors that are locked in the area of the lower edges and the upper edges of the doors by means of separate locking catches.
  • the pivoting of the locking lever is carried out according to one embodiment so that a locking lever two spaced-apart bearing brackets is rotatably supported on the bearing journal, while the other plate-shaped locking lever is rotatably supported between these two bearing brackets on the bearing journal of the catch housing.
  • the support of the spring on the two locking levers is carried out according to one embodiment so that the locking lever with the two mounting brackets in the end bracket connecting the two mounting brackets and provided with the deflection slope and the tightening slope is provided with a blind hole which is open to the other locking lever and receives a spring designed as a coil spring.
  • the width of the receiving slots is larger than the diameter of the holding bolts.
  • the structure of the catch housing is preferably designed so that the catch housing consists of a box-shaped lower part, the side wall of which is provided with recesses on one side, and a box-shaped upper part, the side wall of which is provided on one side and the cover plate with the receiving slots, the receiving slots in the upper part coincide with the recesses in the lower part.
  • a fastening tab is formed on the lower part of the insertion side, which has mutually parallel edges with open, on one predetermined hole spacing designed mounting slots is provided.
  • a further embodiment provides that the deflection bevels of the locking levers in the closing direction to the longitudinal central axis of the receiving slots form an acute angle and the bevels in the opening direction make an obtuse angle Include angles.
  • the acute angle of the deflection bevels brings a larger lever arm relative to the fulcrum of the locking lever than the compression spring holding the locking lever in the initial position when a retaining bolt is inserted. Therefore, the deflection of the locking lever can be done with little force when inserting the retaining bolt.
  • the return springs housed in the hinges of the hinged door may already be sufficient, so that the door is brought into the locking position practically by itself.
  • the obtuse angle of the chamfers primarily serves to ensure that the full force of the compression spring pulls the locked door against the body.
  • the lever arm acting on the retaining bolt is smaller than the lever arm of the compression spring, so that a force transmission takes place. To open the locked door, this increased force must therefore be overcome.
  • the closing forces of the return springs in the hinges must also be overcome.
  • the locking catch according to the invention is accommodated in a catch housing which is composed of the lower part 10 shown in FIGS. 1 and 2 and the upper part 30 shown in FIGS. 3 and 4.
  • the lower part 10 is box-shaped, the cutouts 22 and 23 being made in one side of the side wall 16 and coinciding with the receiving slots 35 and 36 in the cover plate and the side wall 31 of the box-shaped upper part 30 when the two parts are connected to one another.
  • the connection of lower part 10 and upper part 30 can take place via the connecting sleeves 19 formed on the lower part 10 and the connecting pins 33 formed on the upper part 30, which are clamped in the connecting sleeves 19 or held in some other way.
  • Lower part 10 and upper part 30 are preferably designed as metal injection molded parts.
  • the side walls 16 and 31 of the lower part 10 and upper part 30 are provided on the end face with mutually offset connecting webs 21 and 32, so that the overlapping connection between the lower part 10 and the upper part 30 of the catch housing closes tightly.
  • the lower part 10 and the upper part 30 form two parallel receptacles for the not shown holding elements of the doors designed as holding pins. These recordings are formed by the cutouts 22 and 23 in the lower part 10 and the receiving slots 35 and 36 in the upper part 30 and are thus open to one side of the catch housing.
  • This page is called the introductory page.
  • the side of the side wall 16 opposite the insertion side has a central recess in which the base plate of the lower part 10 is offset upwards and carries a bearing pin 17.
  • This raised shoulder 18 of the base plate serves as a bearing for the locking levers to be stored in the catch housing, as will be shown.
  • the raised shoulder 18 is continued outside the side wall 16 as a fastening tab 11.
  • the edges 14 bent at right angles and the integrally formed stiffening webs 15 give the fastening flange 11 sufficient strength.
  • Fastening slots 12 and 13, which are open to the outside and are matched to a predetermined hole spacing, are made in the edges of the fastening flange 11 which run parallel to one another.
  • the catch housing can therefore be fixed to the body with the base plate of the lower part 10, holes of a row of holes made in the body being able to be used.
  • a recess 37 is also made in the side wall 31 on the upper part 30 on the side facing away from the insertion side.
  • the cover plate of the upper part 30 is continued in a semicircular shape to the outside, as the reference number 34 shows. This semi-circular part of the cover plate completes the counter bearing for the locking lever.
  • a plate-shaped locking lever 40 is rotatably mounted on the journal 17. This locking lever 40 extends into the receptacle, which is formed by the receiving slot 35 and the recess 23.
  • the locking lever 50 which is also rotatably mounted on the bearing pin 17, extends into the receptacle, which is formed by the receiving slot 36 and the recess 22.
  • the locking lever 50 is, as the enlarged representations according to FIGS. 7 and 8 show, rotatably mounted on the bearing pin 17 by means of two bearing brackets 51 and 52.
  • the bearing plates 51 and 52 are reinforced in the area of the bearing bores 53 in a ring-like manner, as the reinforcements 54, 55, 56 and 57 show.
  • the locking lever 50 is therefore supported with the reinforcement 54 on the bearing shoulder 18 of the lower part 10 and with the reinforcement 57 on the semicircular part 34 of the upper part 30.
  • the locking lever 40 is supported in the region of its bearing bore 52 on the reinforcements 55 and 56 of the locking lever 50 and can therefore be pivoted between the two mounting brackets 51 and 52.
  • the locking lever 50 has a blind hole 58 which is open towards the locking lever 40 and is provided with an insertion phase 63.
  • a spring 60 designed as a helical spring is held in this blind hole 58 and is supported with the projecting end on a support surface 45 of the locking lever 40.
  • Retaining bolts are attached to the doors as retaining elements, using fastening straps.
  • the retaining bolts are aligned vertically and are inserted into the catches of the catch housing when the doors are closed.
  • the door hinged on the left must first be closed when closing.
  • the associated retaining bolt is inserted into the receptacle formed by the recess 22 and the receiving slot 36.
  • the retaining bolt encounters the swivel-in slope 59 of the locking lever 50, which is pivoted counterclockwise when the retaining bolt is inserted further. If the retaining bolt has been inserted into the end region of the receiving slot 36, the locking lever 50 can be reset clockwise.
  • the locking lever 50 lies with its bevel 61 against the retaining bolt and pulls it with the door against the body. If the receiving slot 36 is deep enough, it can be ensured that the door fits snugly and under tension against the front of the body.
  • the associated retaining bolt pivots the locking lever 40 in a clockwise direction.
  • the retaining pin steers over the Swing-in slope 43 from the locking lever 40 against the locking lever 50, which is firmly again in the starting position shown, but is not yet in contact with the stop 20. If the retaining bolt has reached the end region of the receiving slot 35, then the locking lever 40 pivots counterclockwise and holds the retaining bolt resiliently via its bevel 44, so that the second door also fits snugly and under tension against the front of the body.
  • the locking lever 50 with blocking lugs 62 of both bearing brackets 51 and 52 protrudes into the end region of the receiving slot 35. If the retaining bolt is held above the locking lever 40 in this receiving slot 35, the locking lever 50 can no longer be pivoted, since these locking lugs 62 thereby rest on the retaining bolt. The result of this is that the left door cannot be opened unless the last right door closed previously. Only then can the retaining bolt be led out of the receiving slot 36 by pivoting the locking lever 50.
  • the bevels 44 and 61 of the locking lever 40 and 50 are inclined so that the locking lever 40 and 50 are pivoted against each other when pulling out the retaining bolt.
  • the locking levers 40 and 50 are designed symmetrically with respect to the central plane perpendicular to the pivot axis, they can also be mounted on the bearing journal 17 in a manner reversed by 180 °.
  • the locking catch which is then rotated by 180 ° in the area of the upper edges of the doors on the body, is then described for the locking and blocking function of the just described level locking catch on the lower edges of the doors so that the left door is locked and blocked at the top and bottom.
  • the two locking catches can be created with uniform components solely by different types of assembly.
  • the receiving slots 35 and 36 and the recesses 22 and 23 can be wider than the diameter of the retaining bolts, so that larger tolerances in the attachment of the doors and the attachment of the retaining bolts to these doors can be compensated.
  • the play in the locking direction can be compensated for in a wide range by appropriate design of the receiving slots 35 and 36, wherein in the end position, a tensile force is always exerted on the doors in order to hold them in the stop on the front of the body.
  • the deflection bevels 43 and 59 of the locking levers 40 and 50 are directed in the closing direction at an acute angle to the longitudinal central axes of the receiving slots 35 and 36 of about 30 °, so that when inserting the retaining bolts attached to the doors, first a large lever arm when acting on the Locking lever 40 and 50 is present.
  • the locking levers 40 and 50 can therefore be deflected with little force.
  • the force of the return springs housed in the hinges of the hinged door is often sufficient off, so that the door brought into the closed position practically locks itself. Since the entry path of the retaining bolt into the receiving slot is relatively long, a continuous closing and locking process is achieved.
  • the bevels 44 and 61 of the locking lever 40 and 50 are directed in the opening direction at an obtuse angle to the longitudinal central axes of the receiving slots 35 and 36 of about 110 °, so that when pulling out the fastening bolts attached to the doors, a small lever arm acts upon the locking lever 40 and 50 is present. This lever arm is smaller than the lever arm with which the compression spring acts in the opposite direction on the locking levers 40 and 50. Therefore there is a force transmission, so that the doors can only be opened with greater tractive force. When opening, the closing forces of the return springs in the hinges must also be overcome.
  • the locking catch according to the invention is also possible to use as a simple catch for locking a single door.
  • the locking catch and the retaining bolt only need to be attached to the body and the door in the correct assignment.
  • the retaining bolt is preferably provided with a fastening tab which offers two correspondingly offset fastening options.
  • the Verriegelungsschnäpper can for this application itself can be simplified, however, if it is provided that the snap g etude is only provided with a receiving slot that only one locking lever is rotatably mounted in Schnäppergephaseuse and the pressure spring at this INTERLOCKS support lever and the catch housing.
  • the locking lever with the blind hole and the two mounting brackets is used.
  • the other locking lever can be omitted.
  • the housing parts remain the same except for the number of recesses in the side walls and the number of receiving slots. This can be achieved by simple inserts in the tool, so that the simple catch does not require new tools.
