Abstract

A door-handle fitting consists of a handle pin (13) formed by two pin parts (11, 12) of square cross-section, which are connected to one another in a tension-resistant manner, but rotatably relative to one another, by means of a round coupling pin (14) arranged in axial bores (20, 21) complementary therewith, and which are suitable for cooperation with a respective lock-follow-up part (15, 16) of a divided lock follower (17) of a lock of an anti-panic type. Furthermore, the door-handle fitting has two door handles (18, 19) which are each assigned to a pin part (11, 12) and which can be slipped onto the pin parts (11, 12) from outside and be connected to them in a rotationally fixed and axially fixed manner. At least the coupling region (25) inserted in a pin part (11) has a bolt recess (22), into which engages at least one bolt piece (24) which is arranged so as to be radially displaceable in a radial channel (23) of the associated pin part (11) and which is held in engagement with the bolt recess (22) by the door handle (18) slipped onto the respective pin part (11), but, when the door handle (18) is drawn off from the pin part (11), can shift aside radially to such an extent that the associated coupling region (25) of the coupling pin (14) can be drawn axially out of the bore (20) of the associated pin part (11). <IMAGE>

Description

The invention relates to a door handle set according to the Preamble of claim 1.

With rotatable but axially fixed connection which pin parts are provided with so-called. Panic fittings needed. The two pin parts grip assembly rotatably into the two parts of a divided Lock nut so that when actuating the pin parts by means of a lever handle from both sides of the door Lock different functions can be triggered those for emergencies, for example in the event of a fire Meaning. So z. B. there is a requirement that the The door can only be opened from the outside using the lever handle can if the bolt of the Lock was removed from the closed position. From the inside But in case of danger, the door should always go through alone Pressing on the door handle can be opened, d. that is the bolt must also be removed from the closed position got to.

There is a problem with such lever handle sets in it, the pusher consisting of three main components easy to mon with the actuators animals. When assembling it must be taken into account that not only a perfect independent operation supply of the two lock nut parts is possible, but that too from the actuator, e.g. B. a lever handle forth considerable axial tensile forces can be transmitted to the pusher pin NEN without loosening or even loosening the axially connected components comes.

The aim of the invention is to add another door  to create lever handle set of the type mentioned. In particular, the lever handle set should be in the simplest way se safely and without the risk of loosening or loosening can be assembled. All components are said to be in a wide be brought relative play and rattle-free relative position can.

To solve this problem, the features of the label the part of claim 1 provided.

In this way, the bar recess can be provided ne coupling pin and the associated pin part alone there be locked together that the actuator e.g. B. the lever handle radially in with the coupling pin appropriately aligned pin part is pushed on. This is because the inner wall of the actuating part presses open channel, into which the assigned pin part of the door handle pin is inserted due to suitable dimensions the locking piece radially inwards into the locking recess fung, so that the coupling pin and pin part are perfectly axial are locked together. This connection can be made on both Pin parts may be provided; however, it is sufficient if they only present between a pin part and the coupling pin is.

In any case, it must be ensured that the clutch pinned at least in one of the two axial bores the pin parts of the trigger pin can rotate.

The features of claim 2 are useful in order to insert the coupling pin into the ver with the radial channel see hole of the assigned pin part the insertion depth is automatically determined so that the locking piece and the Bolt recess are aligned radially.  

In an expedient further development according to claim 3 or 4 the stop can change due to abruptly changing diameters real of the axial bore or the coupling area be settled.

In the simplest case, the locking piece according to claim 5 is one Bullet. The locking piece should be made for stability reasons Metal, especially steel.

In general, it is sufficient if each pin on the circumference sometimes only a locking piece is provided. For transmission However, larger tensile forces can also be countered diametrically overlying sides of the pin part radial channels and these receiving locking pieces can be arranged. The Anbrin too supply of several distributed over the circumference of the pin part Bolt pieces are possible.

So that the coupling area of the coupling pin also with the bolt recess engaging bolt piece rela tiv is rotatable to the associated pin part, is off leadership form according to claim 7 useful. This execution form also has the advantage that when inserting the coupling area in the axial bore of the pin part a peri phere alignment is not necessary because of the groove runs all around. In cooperation with the axial stop can therefore be quick, no operator attention installation.

It is particularly advantageous if the locking piece according to Claim 8 is held in the radial channel. With others Words is the locking piece in the radial channel of the pin part held captive, with a radial freedom degree, the engagement and disengagement of the locking piece enabled with the bolt recess.  

Advantageously, the training according to the invention is with Bolt recess and bolt piece only on a pin part of the Coupling pin provided while the other end according to claims 9 or 10 is attached. This attachment must in any case a relative axial definition of Kupp Ensure the pen and part of the pen. Coupling pin and However, the pin part can be rotated axially relative to one another be. It is important that this rotatability at least between one of the two pin parts and the coupling pin is.

The embodiment according to claim 11 is useful if the locking piece also other functions, e.g. B. the one Rotary connection between the pin part and the actuating part via should take.

The invention can also be used in an actuation recording Use channel according to claim 12 with advantage.

The embodiment according to claim 13 is advantageous guarantees that the associated operation part, e.g. B. the door handle, as long as not fully open the pin part having the locking piece is pushed on that can until both parts of the pin are perfectly in the lock nut to sit. The piece protruding beyond the bar recess the coupling pin thus represents a security element, which forces it to be properly arranged Pin parts in the lock nut is guaranteed before loading can be postponed. In an easy way can be flawless without the fitter's attention Assembly can be guaranteed. Only when the pen parts sit wall-free in the lock nut, the bolt piece comes with the bolt recess in radial alignment, so that the Rie penetrate the piece of gel and thus the way for the  Postponing the actuator can make it free.

A rattle-free storage even with a certain game between the individual components is to be ensured the embodiment according to claim 14 useful. The Verspan tion can expediently by the features of the claims 15 or 16 can be brought about.

The invention can thus be particularly advantageous in conjunction Realize with the features of DE-OS 41 21 770. Penetrate through the oblique groove in the handle pin parts de radial screw namely the pusher pin is axially apart pulled otherwise, which is preferably formed as a ball Bolt piece radially outwards against the inner wall of the actuator pressed partially and thus a substantial freedom of play of the individual parts of the pusher pin is achieved.

The invention can also be applied to all other fasteners Use types of actuating part on the trigger pin.

The invention is described below, for example, with reference to Drawing described; in this shows:

Fig. 1 shows an axial section of a door attached to a door handle set in accordance with the present invention,

Fig. 2 is an enlarged partially sectioned view of the pusher pin Seitenan of FIG. 1 with the surrounding parts of the door handle it and the lock nut,

Fig. 3 is a plan view of the pusher pin of Fig. 2 and

Fig. 4 shows a section according to line IV-IV in Fig. 2, wherein above the passing through the central axis 37 through the horizontal plane 38, the embodiment of Fig. 1 to 3 and including two mold further execution are shown.

According to Fig. 1 in a door leaf 40 a dashed lock 41 is housed, the lock nut 17 is divided into two parts 15 , 16 , which are to be operated separately, depending on which of the two lock nut parts 15 or 16 is actuated, different To be able to trigger lock functions. Is the lock nut part 15 z. B. on the inside of a fire-endangered room complete the door 40 and the lock nut part 16 on the outside, it can be provided that the lock nut part 15 when rotating hen in the opening direction actuates both the bolt and the latch of the lock 41 , while the lock nut part 16 when loading in the opening direction only pulls the trap. So it is a so-called panic lever handle set.

The lock nut parts 15 , 16 have axially continuous square table center openings 42 , 42 'through which an inven tion pusher pin 13 is inserted to come into a special rotationally fixed engagement with the lock nut 17 . The pusher pin 13 consists of two axially aligned pin parts 11 and 12 which have a complementary to the Mittelöffnun conditions 42 , 42 'complementary square cross-section, the pin part 11 only the channel 42 ' of the lock nut part 15 and the pin part 12 only the channel 42 of the lock nut part 16 penetrates.

The pin parts 11 , 12 each have axially opposite axial blind holes 20 , 21 with a circular cross section, which are brought from opposite sides onto a coupling pin 14 with a circular cross section in a sliding fit. A in the bore 21 coupling area 26 of the coupling pin 14 is axially fixed by a below described with reference to FIG. 2 axial holding means 29 , but rotatably about the central axis 37 of the Anord voltage in the axial bore 21 .

On the axially opposite side of the coupling pin 14 , a coupling region 25 is provided, which is arranged in the bore 20 of the pin part 11 in a sliding fit and by a locking ball 24 arranged in a radial channel 23 of the pin part 11, which acts radially on the inside into a circumferential groove serving as a locking recess 22 of the coupling area 25 engages with the pin part 11 axially fixed, but non-rotatably connected a related party. The locking ball 24 is determined by the inner wall of a patch with its square-receiving channel 35 on the pin member 11 the door handle 18 in engagement with the indentation 22 Riegelver maintained.

On the pin part 12 from the opposite side a further lever handle 19 is placed, which has a square cross-sectional receiving channel 36 .

On the ends of the door handle neck located in the vicinity of the door leaf 40, rosette flanges 43 are fastened in the embodiment shown, for example, which rest on the surface of the door leaf 40 from opposite sides. Any other rosette arrangement is also conceivable.

Radial threaded holes 44 are provided axially away from the rosettes 43 in the door handle halves, into which radial fastening grub screws 34 are screwed. With their conical tips, the screws 34 engage in axially obliquely inwardly recessing V-grooves 33 in one of the four side surfaces of the pin parts 11 and 12 , respectively, in the manner as that in DE-OS 41 21 770 in detail is described. By screwing the screws 34 into the grooves 33 and pressing them against the base, the pin parts 11 , 12 are pulled axially outwards, the door handles 18 , 19 either directly via the rosettes 43 on the door leaf 40 or in a manner not shown, directly on parts of the lock 41 support. In this way, a play and rattle-free storage of all components is guaranteed.

If the door handle 18 is actuated, it only rotates the lock nut part 15 , while the lock nut part 16 remains unactuated because a relative rotation takes place between the two pin parts 11 , 12 . Conversely, the door handle 19 can actuate the lock nut part 16 separately, without the lock nut part 15 also rotating.

In the following figures, the same reference numerals designate corresponding components as in FIG. 1.

According to FIGS. 2 and 3, the ball, the locking piece forming is 24 held by the radial passage 23 radially inwardly and radially outwardly before seen the end stops 45 and 46 with such radial clearance in the radial channel 23, that after pulling the door handle 18 by pin member 11 the latter can be withdrawn axially from the coupling pin 14 , the locking ball 24 moving so far outward within the radial channel 23 that it disengages from the locking recess 22 designed as a circumferential groove. By contacting the wall of the door handle bore 35 on the ball 24 in the manner shown in FIGS . 1 and 2, the locking ball 24 is held securely in engagement with the locking recess 22 during normal use. The end stops 45 and 46 can be realized by caulking at the two ends of a straight radial channel 23 .

The axial retaining means 29 between the pin 12 and the coupling portion 26 of the coupling pin 14 consist of a circumferential groove 31 in the coupling region 26, two parallel to each other and perpendicular to a surface 47 of the pin member 12 tangential holes 30 in the pin member 12, the axial bore 21 in the shown manner cut perpendicular to the longitudinal axis thereof, and in the two tangent tial bores 30 and the axially aligned order with them to start groove 31 driven clamping retaining pins 32 , whereby the coupling pin 14 and the pin member 12 are held together axially fixed, but rotatable relative to each other.

Of particular importance is the subdivision of the axial bore 20 of the pin part 11 into a region 20 'of the lock nut which is closer to the lock and which has a larger diameter and a region 20 ''of smaller diameter which faces away from the lock nut 17 , so that between the two bore parts 20 ', 20 ''A ring step 27 extending perpendicular to the central axis 34 is formed. Accordingly, the coupling region 25 of the coupling pin 14 is divided into a part 25 'with a larger and a part 25 ''with a smaller diameter, so that an annular step 28 is also present between these two parts.

The ring steps 28 , 27 are arranged axially so that when they lie against one another according to FIG. 2, the locking recess 22 is aligned radially with the radial channel 23 .

Assembly and disassembly of the door handle set according to the invention proceed as follows:

First, the pin part 12 is pushed onto the coupling area 26 until the circumferential groove 31 with the tangential bores 30 comes into radial alignment. Then the retaining pins are hammered into the tangential bores, which are only so long that they do not protrude from any surface of the pin part 12 . The retaining pins are resiliently compressible so that they are clamped in the associated tangential bores 30 after driving.

Then the axially opposite coupling region 25 is inserted into the axial bore 20 of the pin part 11 until the ring steps 27 , 28 come into contact with one another. As a result, the radial channel 23 is automatically radially aligned with the circumferential groove 22 . In this state, the door handle pin 13 is inserted into the axial channels of the lock nut parts 15 , 16 as shown in FIGS . 1 to 3. The pin part 11 thus comes into rotational engagement with the lock nut part 15 , the pin part 12 in corresponding rotary engagement with the lock nut part 16 .

If the lever handle 18 is now placed axially with its square bore 35 on the pin part 11 when the screw 34 is initially unscrewed, then the upper inner wall of the square bore 35 in FIGS . 1 and 2 comes into engagement with the locking ball 24 , so that it is securely in the locking recess 22 is held.

From the opposite side, when the screw 34 is also unscrewed, the additional lever handle 19 is placed axially on the pin part 12 .

Then the screws 34 are then screwed into the sloping inwardly sloping grooves 33 , the door handles 18 , 19 being pressed against the door leaf 40 or parts of the lock 41 and the two pin parts 11 , 12 being pulled apart axially, so that in particular between the Pin part 11 , the locking ball 24 and the coupling pin 14 no more play. By suitably screwing in the screws 34, it can be ensured that there is no excessive rotational friction when the door handles 18 , 19 are actuated.

Due to the relative rotatability of the two pin parts 11 , 12 , which remains intact even with the axial bracing, the lock nut parts 15 , 16 can be actuated separately by separately actuating the lever handles 18 and 19, respectively.

The section lying above the horizontal plane 38 shows the arrangement according to FIG. 2 along the line IV-IV above the central axis 37 .

Below the horizontal plane 38 , two further embodiments are illustrated. Thereafter, the axial bore 35 'in the lever handle 18 ' was initially provided as a circular bore 35 a, from which the corner regions 35 b were then worked out by broaching. In this way, the radial channel 23 is part of the circular bore 35 a opposite. Dement speaking, the radial channel 23 has a larger diameter water and contains a locking ball 24 'with a larger diameter so that it can extend locking between the annular groove 22 and the contour of the circular bore 35 a.

Furthermore, below the horizontal plane 38 in Fig. 4, the possibility is indicated to form the locking piece as an elongated plunger 24 '' extending in the radial direction, which engages in a provided outside the circular bore 35 a ne axial groove 39 . In this way, the coherence between the pin part 11 and the surrounding neck of the lever handle 18 can be further strengthened and improved.

It is of particular importance that, according to FIG. 2, the coupling pin is extended on the side facing away from the lock nut 17 by a piece 48 via the locking recess 22 . If the pin parts 11 , 12 are not axially inserted up to their Solltie fe in the lock nut 17 or are even outside the lock nut immediately at the beginning of the same, the locking ball 24 can not come in radial alignment with the locking recess 22 and is located radially in the area of the piece 48 serving as an assembly lock. Accordingly, the locking ball 24 projects radially beyond the pin part 11 to the outside, and the door handle 18 cannot be pushed open axially. The fitter is therefore forced to position the two pin parts 11 , 12 properly in the lock nut 17 ; Only then does the locking ball 24 come with the locking recess 22 in radial alignment, and the door handle 18 can be pushed axially.
