Definitions

  • Turnbuckle lock with adjustable distance between turnbuckle and housing
  • the invention relates to a rotary bolt closure, consisting of a housing which can be fastened in a door leaf or the like and has a flange and an actuating shaft which is rotatably mounted in the housing and which has a rotary bolt tongue at one end and an actuating mandrel at its other end .
  • a rotary bolt closure consisting of a housing which can be fastened in a door leaf or the like and has a flange and an actuating shaft which is rotatably mounted in the housing and which has a rotary bolt tongue at one end and an actuating mandrel at its other end .
  • a rotary bolt closure consisting of a housing which can be fastened in a door leaf or the like and has a flange and an actuating shaft which is rotatably mounted in the housing and which has a rotary bolt tongue at one end and an actuating mandrel at its other end .
  • Such a closure - in the form of a stepped tongue closure - is from the utility model G 89 09 941.9, see in particular its figure 8, and also from the catalog "EMKA fittings", No. 9, published by EMKA Betschmaschine GmbH & Co KG, Velbert, already known.
  • the adjustability of the utility model is achieved by arranging intermediate pieces of different lengths between the end of the actuating shaft and the tongue, these three parts be connected by means of a common screw bolt, so that - if one still takes into account the presence of the housing for the actuating shaft - there are at least five parts which make up the closure. Taking into account the screw nut used for fastening purposes, there are even six parts. This is disadvantageous, especially since intermediate pieces of different lengths also have to be kept in stock for different lengths.
  • the necessary tolerance compensation is only a few millimeters in size and the load that has to be absorbed by the rotary bolt lock is comparatively low. This applies, for example, to the definition of ventilation flaps, in which several such closures are arranged per flap, so that the load exerted on the individual closure remains relatively small.
  • REPLACEMENT LEAF to keep low.
  • a reduction in production costs is made possible in particular if the number of different components required for the rotary bolt lock, which are required in particular for a specific adjustment range of distances, can be kept as small as possible.
  • Another cost factor is the material that is used to manufacture the turnbuckles. Although metal is very stable, it is quite complex to manufacture. It is therefore desirable to design the rotary latch so that as many of its individual parts as possible are injection-molded from plastic.
  • the design should also be such that the assembly process is as quick and easy as possible.
  • assembly is carried out by screwing a fastening nut onto the outer surface of the housing of the closure, and this possibility is also present in the present case, but in many application areas it is more favorable to carry out the fastening in such a way that Unscrewing a fastening nut - which must be done from behind and thus requires access to the rear surface of a door leaf or the like - can possibly be avoided.
  • REPLACEMENT LEAF molded, resilient tongues go out, which have at their free ends a surface that is resiliently supported on the back of a door leaf or the like and thereby hold the lock housing in the opening of the door leaf or the like.
  • the support surface also has a bevel, so that sheet metal thicknesses of different thicknesses can be provided to a limited extent and still work with the same housing. An adjustability between the flange and the tongue, if any, is not provided.
  • the object of the invention is to design a rotary latch lock of the type mentioned at the outset in such a way that it manages with as few components as possible and, nevertheless, an adjustability of the distance between the latch bolt tongue and the housing, in particular the contact surface of a housing flange on a door leaf front surface. Flap outer surface or the like. And the tongue and thus the area to be gripped behind by the tongue.
  • the possibility of gas tightness should be retained to provide, if necessary, to prevent that from the inside of a ventilation duct, for example closed with a flap, parts of gases flowing from there through the interior of the housing or along the outer surface of the housing from one side of the flap to the other side (i.e. to the outside) can reach. That is, it is also an object of the invention to design the twist lock so that it can be made gas-tight if necessary.
  • the object is achieved in that, in the case of a rotary bolt closure of the type mentioned at the outset, the bearing circumferential surface of the actuating shaft has at least one annularly extending bead or rib (or a plurality of beads or ribs arranged axially at a distance from one another), or several axially spaced rings has extending depressions or grooves, and that the bearing bore surface of the housing has one or more axially spaced, annularly extending depressions or grooves or at least one annularly extending bead or rib, bead or rib profile for the recessing or groove profile is compatible and the inner diameter of the bearing bore area and the outer diameter of the shaft in the area of the bearing circumferential surface are approximately the same and are yielding by at least the profile depth of the groove or depression or bead or rib and thereby the shaft can be pushed into the housing to a depth at which the at least one bead or rib comes to lie axially locking but radially
  • a particularly important setting range is, for example, a distance of 24 to 27 mm between the contact surface of the housing flange on the outer surface of the door leaf (or the outer surface of another arrangement, such as a flap or the like) and the contact surface of the tongue of the rotary bolt and thus the corresponding ramp surface, which is engaged by the tongue of the closure and thereby holds the flap or door or whatever it is in the frame or opening.
  • the main object of the present invention is thus accomplished with very simple means.
  • Such a profile shape would be a sawtooth shape, in which the sawtooth bevel is placed in such a way that it is pushed in along it, while the straight or only slightly beveled part of the sawtooth takes effect when the tongue shaft comes out of the housing in the opposite direction should be pushed out.
  • This pushing out should expediently be more difficult than pushing in, because the load forces which act on the tongue through the fastening and holding process also attempt to push out. But since the cam locks described here are only for small Load tasks are provided, the constructionally limited holding force is sufficient.
  • the flexibility which is required to be able to push the shaft into the housing and, if necessary, to push it out again, can be achieved by means of an axial slot in the housing and / or in the shaft, a slot in the shaft having a certain width must, so that the shaft circumference can be compressed to a certain extent.
  • a slot in the housing does not have to have a width, since it is sufficient for it to be pressed apart in order to obtain the desired flexibility.
  • a plastic having a certain flexibility is used to manufacture the housing and shaft, it is also possible to dispense with such slits, which have certain disadvantages (such as housing weakening, gas leakage, etc.), especially since plastic is also a very inexpensive material and is easy to use can inject desired shapes. Because of the limited forces that can be applied anyway, the strength of the material will generally be sufficient.
  • This plastic material has yet another advantage, namely that the housing can be constructed in such a way that projections extending axially from the housing wall and extending beyond the hole pattern of the associated door opening or the like can have protrusions which are thus formed in depressions in the Housing can be pushed back so that they do not exceed the drilling pattern and thus allow the housing to be pushed into the opening in the door leaf or the like, but which then end up at the door leaf inner wall or the like with one end.
  • the housing is constructed in this way, it is expedient to provide the projections with a triangular shape, the longest side of this triangle representing the fastening edge of the projection on the housing, the shortest side the contact surface on the door leaf inner wall or on the opening edge, and the third side a run-up surface for pressing the projection into the depression in the housing when the closure is pushed into the opening.
  • the second-mentioned bevel allows a certain flexibility with regard to the thickness of the door leaf plate or the like, while the third-mentioned bevel surface makes it easier to insert it, because increasing forces are only gradually required in order to project the projection into the depression in the outer surface of the housing (against its input Spring force), which in turn makes assembly easier.
  • the usually already usual drilling pattern can be used as the drilling pattern, namely a drilling pattern or a breakthrough shape for the closure, which consists of a circle with four constrictions offset by 90 ° to one another.
  • a drilling pattern or a breakthrough shape for the closure which consists of a circle with four constrictions offset by 90 ° to one another.
  • two projections are provided in the area of one constriction and in the area of the constriction offset by 180 °, and if the most protruding areas of the projections are located in the area between the constrictions range is sufficient. This results in investment points through the projections at four points each offset by approximately 90 °, so that there is an overall evenly distributed contact force.
  • the design of the circumference of the housing can be made in such a way that a desired rotational locking of the housing within the breakthrough opening results, as in the prior art.
  • an adjustable cam lock can thus be created, which consists of only two injection molded parts and, on the one hand, is very inexpensive to manufacture, but on the other hand can also be installed very easily due to its special properties.
  • This allows a large number of closures for, for example, a ventilation flap to be provided with relatively little effort, without thereby driving the costs extremely high, and the inexpensive production means that a larger number of closures provide a more uniform, linear fastening force for the flap edges at the opening to be closed is made possible.
  • This means that the internal strength of the flap does not have to be so great, since the forces to be applied between the individual closures and to be exerted on sealing material remain small because of the close arrangement of the closures.
  • the tongue can have a nose for limiting the rotational path, which has a corresponding depression on the end face that defines the rotational range of the housing cooperates, the stop still being effective when the shaft is fully pushed in and also when the shaft is not fully pushed in, the height of the nose and the corresponding depth of the depression to determine the path of movement determine the setting range into which the stop is effective .
  • a stop is not necessary and the nose and the corresponding incision can be dispensed with. Instead, a marking can be provided to identify the position of the tongue on the actuating mandrel or the like.
  • the torque required for actuating the rotary bolt is relatively large, which is advantageous insofar as the risk is reduced that the rotary bolt undesirably moves away from its closed position automatically, e.g. B. with vibrating load.
  • the tongue can also have an offset here, see Fig. 9, or a narrowing or other special shape in order to achieve that even a fully assembled closure with the tongue and then with the housing outer surface through the door opening or the like.
  • Pushed through and then, for. B. can be attached by "clipping" in the manner already described.
  • the insert could in turn be injection molded as a hollow tube, the shrinkage and expansion of the component (eg in the event of temperature fluctuations) advantageously not causing any undesirable distortions due to the wall thicknesses which can then be configured in a uniform manner.
  • the tongue can have a reinforcement insert made of metal, such as steel, or made of glass fiber-reinforced material, which is embedded in the plastic.
  • the profile for the annular grooves or projections can be triangular, sinusoidal, but preferably sawtooth-shaped, with the inclined surfaces preferably pointing in the sliding direction during insertion, as already mentioned. It is also expedient to round off the corners of the triangular or saw-shaped profile, which reduces the abrasion forces which act on the material, which occur both when pushing in or pushing out, but also during normal turning operation.

L'arbre d'actionnement (16) est pourvu d'une langue de verrou tournant (18) à une extrémité et d'une broche d'actionnement (24) ou d'un élément similaire à l'autre extrémité (88). L'écartement (58) entre la langue de verrou tournant (18) et le flasque du logement (46) est réglable. Selon l'invention, la surface de support périphérique (26) de l'arbre d'actionnement (16) possède au moins un bourrelet ou une nervure annulaire (28) ou plusieurs dégagements ou rainures (30 annulaires disposés avec un écartement (32) axial les unes par rapport aux autres. La surface (34) interne du trou de support du logement (14) comporte plusieurs dégaements ou rainures annulaires disposées avec un écartement (32) axial les unes par rapport aux autres, ou bien au moins une rainure ou nervure annulaire. Le profil du bourrelet ou de la nervure est compatible avec celui du dégagement ou de la rainure, le diamètre intérieur du trou de support (34) et le diamètre extérieur de l'arbre sont approximativement égaux dans la zone de la surface de support périphérique (25) et au moins la profondeur du profil de la rainure ou du dégagement, ou du bourrelet ou de la nervure, est variable pour permettre l'insertion de l'arbre dans le logement à une profondeur telle qu'au moins un bourrelet ou une nervure vienne reposer dans un(e) ou plusieurs nervure(s) ou dégagement(s) de sorte que ledit axe soit bloqué axialement mais qu'il puisse tourner radialement.
