Definitions

  • lever handles There are various options for the axial fastening of lever handles.
  • a common solution is to axially connect the inside and outside handles with their square pin. Many different lever handle square pin connections have been developed for this purpose.
  • a second, also widespread, solution is to connect the handles in a radially rotatable but axially fixed manner to their plates or rosettes, which in turn are screwed onto the door.
  • Widespread versions are those in which the pushers are connected to their plates or rosettes by snap rings (DE-Gbm 76 13 330) or by riveting in the factory.
  • This has several disadvantages: the parts that are already connected to each other are more difficult to pack and send than separate pushers and push button bearings.
  • the dealer has a larger inventory, since he cannot or cannot simply combine the same pushers with different rosettes or signs.
  • connections have already been developed that are only added shortly before the fitting is installed.
  • the pusher can be locked in the manner of a bayonet catch with the associated plates or rosettes.
  • the handle that is already connected to the lower part is a hindrance when tightening the fastening screws.
  • a door handle arrangement intended for a car door is also known (US-A-2 341 908, which forms the preambles of claims 1 to 3), in which a fork-shaped retaining spring engages in a circumferential groove of the handle neck in order to axially close it within the door handle bore hold.
  • this fork spring does not form part of the bearing in the unlocked state and is therefore easily lost, it only grips the lever handle neck in the tangential direction, because otherwise it could not be pushed open. As a result, there is only a limited hold of the lever handle neck in the axial direction, particularly in the case of not very deep circumferential grooves. The bolt cannot be dismantled without disassembling the door.
  • a hairpin-shaped spring is accommodated in the bearing part, one leg of which spring engages in a circumferential groove of the door handle neck. By gripping one end of this leg with a tool, the leg in question can be lifted out of the circumferential groove and the door handle can be removed. If the bearing part is not covered by a cover cap, the locking spring is accessible from the outside, so that the lever handle can also be removed by unauthorized persons. In addition, the hold of the door handle is inadequate due to the only one-sided hold by means of one leg of the locking spring.
  • the aim of the invention is to provide a lever handle arrangement of the type mentioned, in which, without risk of losing the force application and transmission members and with an axially flat design of the bearing part, both a problem-free attachment of the lever handle after fastening the bearing part to the door leaf and application of the Cover cap as well as a secure hold of the door handle against axial pulling off in normal use, as well as a problem-free release of the door handle without unscrewing the bearing part and without completely removing the cover cap, without the release mechanism being readily recognizable to an uninitiated person.
  • the force application element can be actuated practically with the cover cap attached or only slightly raised on one side slightly by 2 to 3 mm, so that when the force application element is acted on appropriately, the lever handle can first be released and removed from the bearing part, whereupon the top cap is completely removed and the bearing part can be unscrewed if necessary.
  • the arrangement of the handle or the force application element near the rear surface is particularly important here.
  • the bearing part can first be screwed onto the door leaf, whereupon the cover cap is snapped on and only then the door handle is inserted into the door handle bore and axially fixed by inserting the latch into the circumferential groove.
  • the latch is inserted into the circumferential groove in that the latches are biased radially resiliently towards the circumferential groove and the lever handle is provided on its free end face with a chamfer which is capable of resiliently pushing the latch radially away so that it is finally radial can snap into the circumferential groove when the door handle is inserted far enough into the door handle bore.
  • the latter embodiment is preferred, since in this way it is not necessary to actuate the force application element when the door handle is inserted into the bearing part. Rather, this is moved into the locking position before the cover cap is applied.
  • cover cap is detachably snapped onto the bearing part by means of latching surfaces. In this way, the cover cap can be practically without any other, except for the aforementioned small opening and the door handle through hole
  • Openings are formed, which enables complete coverage of the bearing part and the force application and transmission members and the bolt to the outside.
  • the actuating mechanism is therefore not visible from the outside, nor can it be soiled or damaged by exposure to the outside.
  • the locking surfaces are inclined and long in such a way that the cover cap does not yet spring off from the bearing part when a cover cap which is sufficient to form a pin, screwdriver and / or fingernail is not lifted off and preferably remains in the partially lifted position independently until it is completely snapped open or fully lifted after the door handle has been fitted or removed.
  • the latching surfaces should not be designed so that the entire top cap jumps off the bearing part completely when the top cap is lifted slightly on one side.
  • the design of the locking surfaces should therefore be such that the dead center, clearly jumping off beyond the top cap, is only reached when the top cap has been raised on one side to such an extent that the force application element can be reached through the gap formed.
  • the invention is particularly preferably applied to lever handles in which the handle neck has at its free end a pivot with a reduced diameter, which is separated from the part of the handle neck projecting outwards via a ring step.
  • the cover cap lies axially against the ring step and cannot snap away from the bearing part when the cover cap is lifted on one side anyway.
  • the invention can be used with particular preference because here the cover cap cannot be lifted off the bearing part at all before assembly or disassembly of the door handle, unless the door handle through hole has a larger diameter than the protruding part of the door handle neck.
  • the door handle neck can protrude radially with its projecting part radially beyond the door handle through hole of the top cap, without the operation of the force application and transmission elements lying within the top cap being impaired.
  • a particularly preferred embodiment is characterized in that the latching surfaces are inclined and long in such a way that the force application member can be acted upon through the gap when the cover cap is lifted and disengaged at about 180 ° from the point where the gap formed is furthest .
  • the force application element can be actuated by an impact force with a component directed radially inwards and / or in the circumferential direction. It is also expediently provided that the force application member can be actuated by a torque about an axis lying between the radial and the circumferential direction.
  • the bolts can only be released from the circumferential groove of the lever handle by a radially outward movement. This radially outward movement of the bolts is triggered by an impact force or a rotary movement in the aforementioned sense.
  • the force application element expediently extends approximately to the edge of the bearing part immediately behind the edge of the top cap, it can also be provided that the force application element can be acted upon from the outside by a lateral, preferably essentially radial and straight channel.
  • the force application member is designed as a lever that extends almost to the edge of the top cap.
  • the lever is expediently movable in the circumferential direction.
  • the embodiment according to claim 12 ensures a particularly stable mounting of the radially displaceable latches, the assembly also being facilitated by the two-part design of the bearing part.
  • the bolts can be brought into engagement with the circumferential groove by spring force.
  • the end face of the lever handle neck, but possibly also the latch or latches have a chamfer, so that the latch or latches are pushed radially outwards by the chamfer when the handle neck is inserted axially into the door handle bore, in order then to move automatically snap into the circumferential groove.
  • a particularly simple and economically feasible embodiment is characterized in that only one latch is provided on the circumference, which can be lifted out of the circumferential groove by a lateral force via a lateral inclined surface forming the force application member. It is particularly provided that the inclined surface at the end of the channel is arranged at 45 ° to the direction of movement of the bolt and the channel is perpendicular to the direction of movement.
  • the force application member is an essentially radially extending screw which is arranged in a corresponding threaded hole in a corresponding threaded hole, which preferably extends away from the bolt from the top cap and forms the force transmission member.
  • the embodiment according to claim 14 is particularly theft-proof because it can only be operated with a correspondingly long screwdriver.
  • a structurally particularly compact arrangement is characterized in that the screw is surrounded by a helical spring which acts radially on the shoulder.
  • the circumferential groove should have a rectangular cross-section, into which the edges of the latches, which are correspondingly provided with a rectangular cross-section, engage.
  • a plurality of bolts are expediently provided on the circumference, which are acted upon simultaneously by a single force application element via a transmission forming the force transmission element.
  • a first expedient embodiment with two diametrically opposed bars is defined by claims 17 to 21.
  • the invention can also be used without difficulty in the case of bearing parts designed as an elongated door plate.
  • An advantageous embodiment of this type is characterized in that the bolts around the door handle bore are secant-like rods which are attached to the bearing part in a substantially radially displaceable manner from the locking position in the circumferential groove to the unlocking position.
  • the rods are preferably resiliently bendable, so that in connection with the chamfer on the end face of the handle neck, the handle neck can be inserted into the door handle bore even when the bars are in the locked position, which are then pressed apart until they snap into the circumferential groove.
  • three or preferably four rods should preferably be arranged evenly distributed over the circumference.
  • a further development of the invention also consists in pressing the latches in a resilient and suitable manner radially into the circumferential groove of the door handle in such a way that any radial play of the handle neck or the pivot pin arranged thereon is compensated for within the door handle bore. In this way, related manufacturing tolerances can also be easily compensated for in a simple manner.
  • the bolts and the force application and transmission members should also form part of the bearing part in the unlocking position, ie. That is, that they form part of the bearing before joining and after unlocking the handle, and that the force application member can be acted upon comfortably by means of a pin, screwdriver and / or by hand in the unlocking direction even when the bearing part is mounted on the door with the cover cap removed.
  • a particularly preferred embodiment of the invention is characterized by claims 39 to 54. Due to the designs defined there, a particularly secure hold of the lever handle is guaranteed, although problem-free assembly and disassembly is nevertheless possible.
  • the slide can also be arranged between the pivot axis and pusher opening, as a result of which the entire arrangement then has a greater radial extension only in one direction.
  • the embodiment according to claim 48 has the advantage that such a slide with a very flat tool, for. b. the blade of a very small screwdriver, which is pushed under the edge of the top cap.
  • the embodiment according to claim 54 also ensures a sufficiently stable single-point suspension for the fire emergency, since the bolts are caught in the groove of the handle.
  • the occurrence of such unlocking forces can be prevented, for example, by limiting the circumferential extent of the bolts in the circumferential groove, in that the tangential directions of the circumferential edges engaging with the circumferential groove differ in direction as much as possible from the direction of displacement of the bolts.
  • the flanks of the circumferential groove and the side surfaces of the bolts should be as perpendicular as possible to the lever handle axis. Rounded cross-sections of the circumferential groove and the locking surfaces engaging in it should be avoided.
  • the undesired axial pulling out of the lever handle against the holding forces of the bolts can be effectively countered by arranging more than one bolt, preferably two, three or four bolts, distributed over the circumference.
  • a tangential, straight extension of the edges of the latches engaging in the circumferential groove should be avoided.
  • the peripheral edges should rather adapt to the circular shape of the peripheral groove.
  • a further preferred embodiment for avoiding an unlocking at the wrong time provides that pivot locking means are arranged on the bolts and / or the elements surrounding them, which, when the lever handle is pulled, at least causes the bolt to move out of the circumferential groove of the pivot compared to the normal state when the lever handle is axially unloaded complicate.
  • the inventive idea of this embodiment is to be seen in the fact that when the lever handle is pulled axially, the spring forces holding the bolts in their locking position in the circumferential groove of the lever handle pivot are increased by clamping or frictional forces and stop forces when the door handle is pulled axially outwards .
  • the design should preferably be such that the forces holding the bolts in their locking position increase either suddenly or steadily with the axial pulling force on the door handle.
  • an advantageous practical embodiment is characterized in that the latches are axially displaceable axially by a predetermined small amount of, for example, a few tenths of a millimeter relative to an element surrounding the latches when the lever handle is pulled and that the pivoting means become effective due to this slight displacement.
  • the bolts are also perpendicular to their intended direction of movement, namely slightly movable in the direction of the lever handle axis, which can be used to produce a clamping or friction or stop intervention, the measures according to claims 57 to 59 being expedient .
  • the unintentional loosening of the bolts can be achieved by small projections arranged on the back of the cover plate, to which the outer bolt edges run when they are pivoted outwards by the small piece when the rotating handle is subjected to tensile stress.
  • the tensile load pulls the latches firmly against the cover plate, so that the small projections form an effective hurdle.
  • the depressions in the cover plate only need to be approx. 0.2 mm deep. If the bolts are pulled into this recess when the handle is subjected to a tensile load, an effective stop action is already established.
  • the latches When the handle is joined, however, the latches are bent somewhat elastically by the handle in the direction of the door and thus pressed out of the recess; they can now be pivoted outwards in the ways according to the invention and thus brought out of engagement with the pivot of the lever handle neck.
  • the handle neck is chamfered at its free end so that its front diameter is smaller than the approximately circular opening within the mutually engaging bolt.
  • the front transom edges are preferably also slightly chamfered in the area of the opening, which e.g. can already be achieved by appropriate selection of the punching direction in their manufacture.
  • the bevels of the front chamfer force the bolts apart until they snap into the circumferential groove of the pivot of the handle handle neck.
  • the bolts - due to the pivoting kinematics - of the pusher chamfer moving against them can avoid radial deflection less easily than in the middle of the bolt.
  • the joining of the pusher is consequently facilitated by the fact that the opening enclosed by the bolts is somewhat enlarged in the region of the parting line, somewhat different from the ideal circular shape, as defined in claim 62.
  • the radial space requirement is also small, because the construction has a greater radial extension only in two or even in one direction.
  • the invention can therefore also be used with narrow long-round rosettes or signs for frame doors and even with a narrow sign that ends directly above the handle.
  • the handle remains axially immovable in both directions with the steel cover plate, in the simplest way thanks to the riveted pivot axis, which in this respect fulfills a double function.
  • a bearing part, designed as a rosette 13, of a door handle arrangement consists of an annular bearing part base body 13 'made of plastic, which is covered on the outside and also on the circumference by a thin metal cover plate 13''.
  • the door handle bore 23 is located centrally in the rosette 13, into which the pivot pin 21 provided at the end of the handle neck 20 of the door handle 19 is inserted according to FIG. 2.
  • the dimensioning of the door handle bore 23 and the pivot pin 21 is such that a rotary mounting of the handle neck 20 is achieved in this way.
  • the pivot pin 21 practically penetrates the entire thickness extension of the bearing part base body 13 'in the axial direction.
  • the pivot is only guided in the bearing part base body 13 'and not in the metallic cover plate 13'', the bore 23' of which corresponds to the door handle bore 23 'has a slightly larger diameter.
  • the reason for this measure is the avoidance of scratches in the surface of the pivot pin 21, since the lever handle 19, like the bearing part base body 13 ', is preferably made of plastic.
  • the rosette 13 is provided with two diametrically opposite fastening bores 36, of which a hollow fitting pin 35 extends according to FIG. 2, which is inserted into a corresponding fitting bore of the door leaf.
  • the back 60 of the rosette 13 is in the assembled state on the surface of the door leaf, not shown.
  • a radially directed rectangular flat recess 28 is provided in the front surface of the bearing part base body 13 ', in which a bolt 11 designed as a flat plate is arranged to be radially displaceable.
  • the flat bolt 11 is guided from the front through the metallic cover plate 13 ′′ of the rosette 13.
  • the bolt 11 has three straight sides at right angles to each other and a concavely circular edge 27 facing the pivot 21, which radially engages in a complementarily shaped circumferential groove 22 in the pivot of the lever handle half 20.
  • the curvature of the edge 27 corresponds to the curvature at the base of the circumferential groove 22.
  • the edge 27 and the circumferential groove 22 are arranged concentrically with the lever handle axis 26.
  • a spring receiving space 53 is provided in the bearing part base body 13 ', which is also covered by the cover plate 13' '.
  • a U-shaped spring 37 which is supported radially on the outside of the bearing part base body 13 'and radially on the inside on the bolt 11, as a result of which it is biased into the locking position shown in FIGS. 1 and 2.
  • a projection 18 is bent from the bolt 11 to a receiving space 61 via a bend, which has a 45 ° inclined surface 12 which extends through a channel 33 extending straight from the side of the rosette 13 by means of a pin or screwdriver is achievable.
  • the receiving space 61 is sufficiently large in the radial direction to allow the bolt 11 to radially spring out to such an extent that it comes out of engagement with the circumferential groove 22.
  • the rosette 13 is completely covered by a cover cap 16, the edge 15 of which laterally surrounds the rosette 13 and extends so far that its rear surface 62 is flush with the rear surface 60 of the rosette 13.
  • the top cap 16 completely covers the rosette 13 including all the parts arranged on it.
  • the cover cap has a door handle through hole 24 which has a significantly smaller diameter than the part of the door handle neck 20 projecting outwards.
  • a radial clearance 63 which corresponds to the radial clearance between the pivot pin 21 and the cover plate 13 ′′.
  • the present between the pivot pin 21 and the projecting part of the pusher neck 20, extending in a radial plane ring step 25 is axially on the surface of the top cap 16 or is so small an axial distance that the annular gap 63 is not visible from the outside.
  • the edge 15 of the top cap 16 at the location of the straight lateral channel 33 can have a small opening 14 corresponding in cross section to the channel cross section, through which a pin can be guided to the inclined surface 12.
  • a radial movement of the bolt 11 then takes place outward via the inclined surface 12, which acts as an inclined plane, with the spring 37 being compressed.
  • the top cap 16 in the region of the channel 33 on one side as far from the Rosette 13 can be lifted off, that the channel 33 is exposed and, analogously to the way through the small opening 14, a pin or a screwdriver can be inserted into the channel 33 to actuate the inclined surface 12.
  • the cover cap 16 must be so thin and elastic that this one-sided lifting with elastic deformation of the cover cap 16 is possible. Through the ring step 25, the remaining part of the top cap 16 is held flat on the rosette 13 during this process.
  • the assembly of the lever handle arrangement described proceeds as follows: First, the rosette 13 is screwed to a door leaf in a conventional manner by means of the fastening holes 36 and bolts, not shown. Here, the fitting pins 35 penetrate into a corresponding fitting hole in the door leaf.
  • the cover cap 16 is then snapped onto the rosette 13 by means of the latching surfaces 38.
  • the door handle is then axially inserted through the door handle through hole 24 of the top cap 16 into the door handle bore 23.
  • a chamfer 31 provided on the free end of the pivot pin 21 pushes the bolt 11 radially outward against the force of the spring 37, so that the pivot pin 21 can finally reach the position shown in FIG. 2, in which the bolt 11 under the action of the spring 37 snaps into the circumferential groove 22.
  • the door handle 19 is now rotatably but axially fixed to the rosette 13.
  • the handle neck 20 there is also the usual square hole, not shown, and when the handle neck 20 is inserted into the door handle bore 23, the square pin, not shown, is simultaneously inserted into the square hole in question.
  • the door handle can be disassembled by inserting a pin into the channel 33 either through the small opening 14 or through the gap which arises when the cover cap 16 is lifted on one side, as a result of which the bolt 11 is displaced radially outwards and the edge 27 comes out of engagement with the circumferential groove 22. Now the trigger neck 20 can be pulled off axially; the cover cap 16 can then be completely removed from the rosette 13 and the rosette can then be unscrewed from the door leaf unhindered.
  • a certain slight bearing play of the pivot pin 21 within the door handle bore 23 can also be compensated for in a simple manner by a sufficient radial pressure of the spring 37.
