Definitions

  • the invention relates to a locking device on solid wall doors, in particular of caravans, with an inner lock, the box housing to be attached to it supports an inner handle for actuating and locking the latch, which is preferably equipped with a latch head, and with an outer lock, the housing of which is connected to the inner lock via wall-penetrating spacer bolts is connected and in addition to a bolt pull-back handle has a lock cylinder for actuating the bolt lock of the inner lock.
  • Such locking devices known in the market have a twist grip as an externally accessible latch pull-back handle.
  • the gripping background is created by forming a plate-shaped retracted front plate into which the hub of the rotary handle extends and also a part of the handle body itself.
  • Such rotary handles have disadvantages in that the fingers of the gripping hand pass through the hub onto the two equally long wings of the handle split up. A powerful actuation is therefore not guaranteed in every case. For ergonomic reasons there is therefore limited acceptance.
  • the object of the invention is to design a generic closure device in a technically simple, stable manner in such a way that not only is the method of operation improved ergonomically, but the movement initiated is transmitted to the device of the closure device in a favorable flow of force.
  • the bolt-pull-back handle is designed as a handle-pivot lever located at a distance from the outer surface of the door, which is mounted on a pin to be fastened through the wall and projects with its opposite end into the outer lock housing to be fastened with only hook engagement in the door-mounted lies in front of a shoulder of an intermediate lever which is pivotably mounted in the outer lock housing and which has a driving projection which pivots in the direction of the bolt displacement.
  • the assembly and disassembly is also much easier.
  • the spacing from the outside of the door leaves a generous rear grip area for the operating hand; the handle swivel lever can thus be grasped with an uninterrupted row and the fingers of the operating hand.
  • higher actuation forces can also be applied, which are safely transmitted to the intermediate lever by the hook engagement, which in turn interacts directly with the bolt.
  • the intermediate lever is spring-loaded in the direction of its basic position.
  • the spring forces can be selected very specifically. So z. B. the pivot lever have a stronger spring than the bolt.
  • a favorable embodiment of the intermediate lever also consists in the fact that it is frame-shaped and comprises the lock cylinder.
  • the pin of the handle pivot lever forming the axis of rotation lies behind a supporting flange of the pin which is placed on the outer surface of the door within the door.
  • the cone is like this completely out of sight.
  • An inexpensive accommodation space is particularly available in those cases in which the locking device is to be assigned, for example, to a caravan door, which doors are designed as solid doors and which have the corresponding material thickness.
  • the free end of the handle pivot lever and the attachment of the hook together with the outer lock housing form pivot limit stops.
  • the procedure is such that the free end of the handle pivot lever is assigned a corresponding outer wall section of the outer lock housing as the counter-stop defining the basic position and the hooking the underside of the ceiling of the outer lock housing as the counter-stop determining the open position.
  • the corresponding resources do not require any additional components; they are already existing structural elements of the closure device.
  • the measure that the pin is assigned in the way of the plug-in / snap-in connection proves to be advantageous in terms of assembly technology, with a bearing projection at the free end of the handle-pivoting lever having a coaxial stub axle pair with a downward direction in the plug-in direction that goes back to the base of the bearing projection wide surfaces increasing ramp slope.
  • the handle swivel lever can thus be brought into hooking engagement with the outer lock and then all that is required is to insert the end on the bearing side into the swivel bearing on the door side.
  • the locking device V according to the invention is located on a door 1, for example that of a caravan 2.
  • the locking device V comprises an inner lock 3 and an outer lock 4th
  • the inner lock 3 sitting on the inside of the door 1 has a box housing 5 to be attached to it.
  • the horizontally aligned bolt 6, which is slidably mounted therein, can be actuated via an inner handle 7.
  • the latter is designed as a rotary lever.
  • the bolt 6 is in the locking engagement direction to the striking plate (not shown in detail) under the load of a return spring or locking spring 8 supported on the box housing side.
  • the head of the bolt is realized as a latch head 9, that is to say beveled in the customary manner.
  • the so-called bolt tail 11 In the region of the end facing away from the bolt window 10 of the inner box housing 5, the so-called bolt tail 11, the latter has a driving surface 12 lying transversely to the bolt displacement direction. This extends in the area of action of a rotary cam 13 of a bolt lock 50 of said inner handle 7.
  • the rotary cam 13 passes through an arch slot of the ceiling of the box housing 5 and pivots about a geometric horizontal axis xx.
  • the rotary cam 13 enters the displacement path of the bolt 6, so that it is then secured in the locked position from the inside of the door.
  • This lever position is designed as a latching defined position.
  • the locking means result from Fig. 5 and are designated 14. It is a spring-loaded locking pin which engages in a fixed groove 15 in a bearing neck 16 of the box housing 5 and is controllable.
  • the locking stop on the bolt side, which interacts with the rotary cam 13, bears the reference number 17.
  • a torsion spring 18 wound around the bearing neck 16 loads the inner handle 7 in the direction of the basic position thereof shown in FIG. 8.
  • the inner handle 7 continues in the direction of the door 1 into a central driving mandrel 19.
  • This is operatively connected to the inner handle 7 and is rotatably seated in the cylindrical cavity of the bearing neck 16. It is axially secured via a snap ring 20 and is in a coaxial coupling connection with a locking cylinder 21 of the outer lock 4.
  • the latter extends also in said axis xx.
  • the locking cylinder-side rotary driving projection 22 is a flattened extension of the inner end of the locking cylinder 21. It engages in a coupling cavity 23 of the driving mandrel 19 in a plug connection while leaving a certain rotational clearance.
  • Driving slats are formed on the cavity wall as rotary driving flanks.
  • the locking cylinder 21 is seated in a cylindrical receptacle 24 of a housing 25 of the outer lock 4.
  • the locking cylinder is implemented as a rotating cylinder. His key is shown in a pegging assignment to me 26 designated.
  • the cylindrical receptacle 24 is formed by a socket 27 'aligned from the ceiling 27 on the inside of the housing, the lateral surface of which can be cylindrical or weakly tapered towards the free end, but on the other hand could easily have a square cross-section on the outside.
  • one of the other housings of the same serve as spacer bolts 28.
  • a total of four spacer bolts 28 arranged close to the corner are molded onto the housing 25 that are supported with their free end inside the box housing 5.
  • the ends of the spacer bolts 28 have a receiving cavity for the entry of the usual fastening means such as screws.
  • said spacer bolts 28 also have congruent openings 28 ', for example bores in a base plate 29 of the box housing 5, which base plate 29 has an opening 30 in the center for the passage of the functional parts of the outer lock 4.
  • These functional parts include transmission elements of a handle swivel lever S which actuates the above-mentioned locking bar Sp from the outside as a locking bar retraction handle.
  • This extends in a bridge-like manner (distance A) and thus leaves a sufficient rear gripping space 31 in front of the outer door surface 32 of the door 1.
  • the handle pivot lever S unloads in the opposite direction for the free extension of the bolt 6 and is pivotable at the end, ie at the right end a vertical pin 33 mounted on the door side.
  • the storage takes place in a vanishing within the thickness of the full door Bearing block 34, which closes cleanly on the outside of the door surface 32 with a flat support flange 35.
  • a fastening screw 36 extending from the inside of the door is screwed in from the plug-in end of the bearing block 34.
  • the pin 33 sits on a bearing projection 37 of the somewhat widened end a of the handle pivot lever S. The widening is chosen so that it essentially corresponds to the outline of the support flange 35. A gap 38 corresponding to the swivel angle requirement between the support flange 35 and the thickened end a of the handle is taken into account.
  • the geometric, vertical axis of rotation of the pin 33 is designated y-y in the drawing.
  • the opposite, other, free end b is merely hooked to the outer lock housing 25 to be attached on the door.
  • the hook bears the reference number 39. It is a double-angled structure, the first leg I starting from the end b being essentially parallel to the space extends to the outer door surface 32, at most with a slight acute-angled angle in the bolt exit direction; it then adjoins a section II lying perpendicular to the said outer door surface 32, which merges into a leg III which in turn points in the exit direction of the bolt and thus runs parallel to the bolt displacement or outer door surface. While the first two legs I and II are of approximately the same length, the third leg III has a significantly shorter length, approximately in the range of one third of the length of one of the first mentioned legs.
  • the hook 39 works together with an intermediate lever 40 as a movement-transmitting element.
  • the latter is pivotally mounted in the outer lock housing 25 so as to be pivotable about an axis 41 aligned parallel to the pin 33 or its geometric axis y-y. It is a double bearing using stub axles, which are either formed on the intermediate lever 40 or paired bearing tabs 42 of the outer lock housing 25.
  • the intermediate lever 40 has an angular design and is also shaped into a frame.
  • One angle leg 40 'of the intermediate lever 40 assumes a substantially perpendicular position to the outer door surface 32, while the other angle leg 40sch extends in the basic position substantially parallel to the relevant reference plane.
  • the latter angle leg 40 ⁇ forms at its free end facing the inner lock 3 a shoulder 43 which is overlapped by the hook 39 or its leg III. Said shoulder 43 is rounded transversely in the pivoting movement of the functional parts.
  • the paired angle leg 40 ⁇ includes the area occupied by the lock cylinder 21 and its bearing part.
  • the crossbar of the frame forming the shoulder 43 is designated 44.
  • the parallel crossbar 45 is approximately at the middle level of the other angle leg 40 'and beyond the lock cylinder 21st
  • the free ends of the pair of angle legs 40 ' also form a convex rounded driving projection 46. This is in the basic position on one of the driving surface 12 corresponding, ie level driving surface 47 of the bolt tail 11.
  • the two mirror-symmetrically provided driving surfaces 47 are formed on the transom tail in the region of the geometric axis yy of webs 48 which are formed parallel to the said axis (cf. FIG. 8).
  • the intermediate lever 40 is spring-loaded in the direction of its basic position (FIG. 5). These springs are molded onto the intermediate lever 40 as tongues 49. The latter are rooted in the apex region of the angular intermediate lever, that is to say in the region of the axis 40, and extend freely in the direction of the handle pivot lever S, projecting beyond the plane of the transverse web 44. You will find your spring support bearing on the inside of the ceiling 27 of the housing 25.
  • the tongues 49 can be preloaded.
  • the tongues 49 arranged in pairs also hold the handle pivot lever S in the basic position in a shake, in which the free end of the handle pivot lever S and the attachment of the hook 39 together with the outer lock housing 25 form movement stops.
  • This stop-forming ceiling section bears the reference symbol 51.
  • the stop position in the open position of the handle pivot lever S is shown in Fig. 7.
  • the hook 39 extends through a window 52 of the housing 25.
  • the pin 33 is simply assigned by way of the plug-in / snap-in connection.
  • the direction of insertion is opposite to the arrow z.
  • the pin 33 thus enters its bearing block 34 on the transverse side.
  • the bearing projection 37 is provided at the end a of the handle pivot lever S with two molded-on stub axles forming the common pin 33.
  • the stub axles extend coaxially to one another and point in the vertical direction in opposite directions from said bearing projection, i. H. of its wide areas. The rest is achieved in that the stub axles are bevelled back to the height of the wide areas.
  • the run-up bevels running in the plugging direction, converging in the plugging direction are designated 33 '.
  • the bearing block 37 gapes slightly during the plug-in / latch connection in order to close again due to the restoring force. This connection is irreversible. A reversible assignment is of course also possible by providing an expansion path.
  • the bearing block 34 can also be assigned to the journal 33 beforehand.
  • the opening of the unlocked closure device V from the outside happens simply by exercising a pulling movement of the handle pivot lever S in the direction of the arrow z.
  • the hook 39 which overlaps the shoulder 43, pivots the double-armed intermediate lever 40 against the spring loading of the tongues 49 into the position shown in FIG. 7.
  • the driving projections 46 provided in pairs pull the latch 6 over the driving surface 47 into the release position of its latch head.
  • the latch function is available at all times in the unlocked position.
  • a left-handed rotation of the same leads to the actuation of the bolt lock Sp in the same way, namely with a correspondingly high position of the inner handle 7 in the position shown in FIG. 8 in dash-dotted lines.
  • the intermediate lever 40 is blocked by said bolt lock Sp.
  • Corner gussets 40 ′′′ on the shoulder bar side additionally stabilize the frame-shaped intermediate lever 40.
