Description

The invention relates to a door stay according to the preamble of Claim 1.

DE 41 23 775 A1 describes a door stay, in which one with Door holding rod provided with locking markings with one end at one the door assembly parts door and door pillar is hinged and with its other end in a holder housing made of metal, which on the corresponding other door arrangement part can be fixed, can be passed through. Here, on the one hand, the holding rod is in the holder housing Abutment roller rotatably arranged with one without locking marks trained surface of the support rod is in contact, and on the other Side a vibrating element designed as a cage on a metallic pin stored, which passes through the holder housing parallel to the abutment roller. The The cage has a load roller that is in contact with the door support bar arrives and by the bias of a coil spring Torsion spring loaded the cage. The torsion spring is with both of them coiled sections mounted on the pin, the ends of the Support the torsion spring against the holder housing and one of the two Load arm connecting winding sections acts on the cage. The known door arrester has a number of shortcomings, in particular, the assembly effort and the variety of parts are for high Manufacturing costs responsible. The geometry of the holder housing is there a large number of parts is to be provided, which makes the Manufacture of the corresponding sheet metal blanks with correspondingly high costs brings itself. The introduction and setting of the pivot axes of the cage and the loading roller or the abutment roller forming pins requires this production-technically complex provision of holes and elongated holes in the sheet metal cutting, which is undesirable due to tolerance problems Fluctuations in the holding forces of the door arrester. The storage of the Torsion spring on the pin requires greasing the two parts in order To avoid squeaking sounds, the effect of greasing with prolonged Use or when a vehicle is high due to sun exposure Assumes temperatures, subsides quickly. Furthermore, the roles create when their ability to roll deteriorates, annoying squeaking noises are undesirable and at the same time lead to increased wear on the roller and Guide bar because the parts for a mutual rolling and not for one Are designed to slide. In addition, the squeaking noises penetrate undamped outward. The actuation resistance of the door stay changes via its lifespan, which makes it initially pleasant Locking behavior is gradually becoming distracting. The assembly of the Parts must be in an order due to the preload of the torsion springs take place in which the door support rod is first by a corresponding Opening in the holder housing and then the torsion spring and the cage will be interspersed with the pen, which will make this resulting installation unit when installed in a motor vehicle difficult to handle is. The well-known door lock is heavy and contributes to one Increase in the total weight of the vehicle. Finally the well-known door arrester because of its unattractive appearance and the externally accessible components and because of its Corrosion sensitivity only on the inside of a door arrangement part assembled, which makes accessibility poor and the installation effort are significant.

DE 196 32 630 A1 (= EP 0 824 176 A) describes a door arrester which operates according to the same Functional principle works like the one described above. The Door arrester has a handrail which is opened by an opening Receiving part, which consists of sheet metal, is passed through. To the The receiving part is a bearing shaft on which a swivel part is pivotally arranged and that by the load of a spring or their Suspension fork is shifted towards the door support rod, one Bearing roller made of plastic, which sits on a bearing pin made of metal, thereby is pressed against the door support bar. On the opposite side, on which the Recesses of the door support rod are arranged, is also made Plastic-made bearing roll on a bearing on the receiving part Bearing pin made of metal arranged and engages in the recesses. In addition to the female part, which also has the holes for fixing has a door spar, a cover made of plastic is provided, the also has a passage opening for the door support rod and on the receiving part is slipped on, one mounted in the receiving part Bearing shaft also penetrates the cover. All essential parts of the Door arrester are mounted on the receiving part as a supporting part, and also the receiving part is fixed to the body of the vehicle, so that the Plastic cover only acts as a covering, but not as a functional or load-bearing part of the door stay. Overall are Manufacture and assembly of the known door arrester complex and expensive.

DE 44 34 028 C2 shows another door stay of this type, in which in a vibrating element in the manner of a cage in a metallic housing is arranged, which is arranged on a first shaft on the housing is pivotally mounted and in which a roller on the vibrating element is stored, which is pressed against the narrow side of a support rod. On the the oscillating element facing away, formed with locking recesses Another shaft is mounted on the narrow side of the support rod, who carries a counter roller made of soft plastic. Manufacturing and assembly the known door arrester are complex and expensive. Furthermore, such tend Counter-rollers, which are made of a soft plastic, due to the stress to form grooves in the roller, which is why heavy doors are replaced regularly by metal rollers have to. In order to achieve sufficient strength, such are soft Plastics regularly require metallic substrates, making a unwanted variety of parts and materials.

DE 44 23 819 A1 shows a door arrester of a different type, one under Ball standing under pressure, in which a door support rod with one through Spring loaded ball connected in a guide element is connected and with a profiled locking rail which has locking recesses, interacts and defines preferred opening positions of the door. The Body-side housing is made of plastic. A vibrating element or another rigid element that causes a pivotal movement in the Housing is not to be arranged.

DE 94 178 83 U1 or DE 198 22 098 A1 or DE 1 459 176 A1 or DE 40 09 844 C2 show yet another type of door lock, at which a door support rod can be moved through a plastic housing, the flat surfaces of the door support rod between two of springs acted on, allowing axial feed movement sliding bodies, the can also have rollers or can consist of hard plastic, be braked. A vibrating element or other rigid element that is too a pivoting movement in the housing is not to be caused intended. The end of the handrail usually has a stop, which may include a buffer or the like.

DE 29 44 766 A1 or FR 2 666 616 A1 describe a door arrester simple design, with the elastically preloaded rolling elements along the Flat side of the retaining stem provided with bulges braking cause and at the ends of the elastomer body from a housing in Protect the area of the slot recess for the passage of the door retaining bar and a compressible stop for the end of the door handle bar form.

DE 85 093 74 U1 shows a lock for windows and the like, in which a pair of rollers mounted in plastic holders against the flat surfaces a handrail under the pretension of springs made of elastic rubber Profile pieces are pressed. The holder with the rollers are at Sliding thickening of the holding rod swivels past and against the compressible profile pieces pushed. Such a determiner, the one lightweight object due to the friction of the touching Brakes surfaces, cannot be used for heavy vehicle doors. Also, the rubber-elastic profile pieces do not meet the requirements for Service life of a motor vehicle door arrester, the several thousand load changes must exist without a noticeable change in the holding torque. In particular are the forces required to move the handrail in push and in Pull direction of the handrail different. In addition, the manufacture and assembly of such to be assembled from many individual parts Locks are time-consuming and costly.

DE 74 350 37 U1 describes a vehicle door arrester, in which in one Housing a passage opening is provided for a door handle, which has raised bulges, one on the housing arranged strut is so flexible and pliable that it when let the bulge pass out or be bent together. The strut can be supported by a spring. A disadvantage of that Known door arrester is first of all the fact that the holding forces in Opening direction and closing direction are different. Furthermore, at sudden load changes the holding forces completely canceled out what a sudden knocking out of the vehicle door can result. To the To be able to effectively define the handrail are bulges of the Handrail required on the side facing the strut. Finally a flexible strut does not meet the requirements for the service life of a Motor vehicle door arrester, the several thousand load changes without noticeable There must be a change in the holding torque.

DE 27 31 731 A1 describes yet another type of door arrester for Motor vehicle doors, in which two plastic sliders through as springs trained rubber body at an angle of 45 degrees to a support bar are delivered, with a first braking surface of the sliders on the Flat side of the door support rod rubs, and a second, outer sliding surface a housing wall of a housing which is knocked outwards is present, in particular to achieve an adjustment in the event of wear the brake wedges, bulges are formed in the door holding rod and preferred locking positions or resistance when opening further define. The well-known door arrester enables a uniform one Holding the handrail in the opening and closing direction, but also here applies that the requirements for the service life of a motor vehicle door arrester, the several thousand load changes without any noticeable change in the holding torque must exist, not be met by the rubber bodies. Beyond that assembling for the admission of the rubber body and the brake wedges of two housing parts with a plurality of bends required.

DE 574 787 C describes a door hinge in which a strip of leather is arranged directly on the inside of a door jamb without a housing, um with a stop cushion that in the end of a door support bar is arranged to dampen the impact.

It is the object of the invention to provide a door stay according to the preamble of Claim 1 to create an inexpensive and reliable finding a motor vehicle door.

This task is performed with the door arrester mentioned at the beginning according to the invention with the characterizing features of claim 1 solved.

In the door arrester according to the invention, they act in the holder housing arranged vibrating element and spring member together to by the To pass through passage opening passing through and in determine preferred locking positions such that an increased tractive force the door connected to the handrail must be attached to this to move out of the locked position under tension of the spring member. The Door lock according to the invention can be easily assembled, has a reduced weight and improved sound absorption properties. Further it no longer emits practically any noise.

Preferred door locks of the aforementioned type stand out expediently characterized in that the spring as a torsion spring made of metal or steel has two winding sections, between which a suspension fork is formed, the spring force on the vibrating element as possible transmits torque-free, furthermore expediently the oscillating element applied to the narrow side of the support rod, that is, the pivot axis of the Vibrating element extends transversely to the plane in which the flat surfaces of the Handrail are, preferably the locking recesses on the Vibrating element facing away from the narrow side of the support rod.

According to a preferred embodiment of the invention, the Door arrester a first housing part of the housing, which is injection molded is made of plastic. The manufacture of the first housing part Plastic advantageously allows the housing to be designed in such a way that the outer contour of which can be designed independently of the interior, furthermore the inner division of the first housing part in adaptation to those to be accommodated Parts of the door arrester can be designed, making the aesthetic Overall impression of the door arrester in relation to the visual appearance is improved. For example, the housing parts can be stacked be formed. Furthermore, the production of the plastic parts enables the most extensive encapsulation of the inner life in the injection molding process of the door arrester, which means less contamination and moisture attack becomes sensitive, causing the case on an outside of a Door assembly part can be mounted. In particular, a housing in the door arrangement part in a formed in the outside thereof Countersink can be added to the outer contour of the housing is adapted and in particular with the color of the plastic the subsequent painting, if necessary with simultaneous painting with the Door arrangement part, is optically inconspicuously placed. Another advantage of Designing the housing from essentially plastic consists of that the function of the holder housing is not due to mechanical deformations can be adversely affected. It is both possible to use the spring link in the plastic housing part already during the injection molding process store and overmold as well as this later in the Insert holder housing.

Preferably, the first housing part comprises recesses in which the Spring member can be received circumferentially, so that, for example, a Spring member made of metal or another spring storage material in this provided recess of the first housing part can be fitted or can also be replaced in the event of a defect. Is particularly preferred a formation of the recesses, in which grooves in the recesses are provided, which are intended to adjacent turns of the Take up spring member and this by a between adjacent Keep depressions in the groove of the protruding web at a distance. This will the risk of squeaking windings of the spring member at the Operation is reduced, and at the same time can be difficult to dose There is no lubrication. The grooves are preferably formed by the shape of the Part of the housing already specified and the diameter of the turns or adapted windings of the spring member, it being optionally possible produce the grooves in that the spring member in the shaping of the the first housing part is already inserted into the mold by injection molding. Preferably, however, the spring member is only in at a later time inserted the first housing part. It is possible in the area of the webs that protrude on the inside towards the inside of the recesses, corresponding depressions on the outside of the first. housing part provided. There is preferably one for each winding of the spring member imaginary helical groove provided, being by the not completely circumferential environment of the spring link this groove outside the areas of the recess in the first housing part is interrupted. Through the It is in particular an advantageous embodiment of the cutouts with the grooves Conveniently possible, a spring element with turns already wound at a distance use, which has the advantage of a special low noise.

The first housing part also preferably has a receptacle for the Vibrating element in which this can be used so that it is pivotally mounted. This makes it possible, for example, that Adapting the vibrating element to certain dimensions of the handrail, and Pairings of vibrating element of different sizes in the same housing and to arrange the handrail. In particular, the recording is advantageous for the Vibrating element spatially from the recesses for the spring member delimited, for example, the recordings are in a central section and laterally extending the two cutouts in the central section outer portions of the housing arranged.

The receptacle for the vibrating element supports a cylindrical area the same circumferentially, the circumference encompassing approximately 180 °. In the case of a larger scope, one is advantageously at least partially Circumferentially cylindrical section of the vibrating element held clamped, a by the selection of the plastic material clamping resilient bracket is created.

The first housing part preferably also has projecting ribs which a shift in the direction of the axis of the cylindrical portion of the Limit the vibrating element in the manner of stops, the ribs preferably with little play a stop for the over form cylindrical circumference of the vibrating element projecting portion.

The housing preferably has a second designed as a cover Housing part on that the first housing part of the housing in that Closes the level, for example by screwing or clipping, through which the other components of the holder housing into the first Housing part can be used, providing protection against contamination and water entry is further improved. Expediently in this case the cover includes that surface of the door arrester which is against the door arrangement part comes into contact, so that the door arrester in installed condition cannot be opened by removing the cover. It is possible to physically close the spring member with the second housing part connect so that the bias of the vibrating element by insertion of the second housing part is only initiated. Here, the spring member can projecting from the second housing part nose element, which at Design of the lid made of metal or plastic by bending is pushed away from its position and is thus biased in the opposite direction. A game for recording the second can then be particularly advantageous Housing part in a corresponding recess of the first housing part be provided so that by tightening a screw Door arrangement part increases the bias of the vibrating element and thus the effect of the spring member is variably adjustable. Alternatively, too a metal spring can be integrated or used on the second housing part for example in the manner of a coil spring that of the support rod facing away surface of the vibrating element. Preferably that is second housing part made of the same plastic by injection molding like the first housing part, and according to a preferred embodiment the two parts can even be interconnected, in the manner of a Butterfly hinge, designed and collapsible be made. In this case there is only one locking device on one of the two housing parts which engage in a recess in the other part, required for mutual locking.

According to a preferred variant of the invention, this can also be done One-piece oscillating element in the injection molding process with the first housing part be produced, with a narrower defining a butterfly hinge Bridge the two parts together defining a swivel axis combines.

Are preferably on one of the first and second housing parts Spring supports for supporting spring legs as a torsion spring trained spring member provided that at a particularly inexpensive Design in one piece from the material of the respective housing part are produced, for example by a plastic projection in the first Housing part or by a depression in a lid formed from sheet metal of the second housing part. Alternatively, in the housing part Threaded holes can be provided in which the supports by screws are realized and are axially displaceable in the direction of the threaded hole, so that the bias of the spring member preferably from outside the Housing is adjustable. Alternatively, it is possible to define the requirements in certain e.g. indicated by lines of weakness from the second housing part Provide sheet metal sections by a mortising tool or the like bent on the outside along the line of weakness and so in their inclination and so that the loading of the torsion spring can be changed. Finally can be provided that the requirements after assembly of the Housing by means of a stamp-shaped tool with permanent deformation of the housing part in its wall, if necessary with heat become. Up to this measure, the spring member can remain unstressed that e.g. insertion of the handrail with little force is possible.

The passage opening of the housing is expediently dimensioned in such a way that that the support rod has at least one of its ends through the Passage opening is feasible, so that the handrail and with Enclosures equipped with interiors also interlock with one another afterwards can be brought without the housing or in the housing intended parts must be dismantled. Preferably the Handrail on the through the spring member and the vibrating element predetermined holding forces adapted and points to the circumference of the contour corresponding contours of the oscillating element adapted contours of Recesses on.

According to a preferred embodiment of the invention, the vibrating element is designed as a one-piece plastic part, which is produced as a solid material part by injection molding. The oscillating element can be inserted into the housing irrespective of the selected housing material, it preferably having a cylindrical pin section, the axis of which coincides with the pivot axis of the oscillating element. The cylindrical pin section can be supported circumferentially, the surface quality of the plastic part, in particular during a sliding movement in a correspondingly shaped receptacle of the plastic housing, having favorable surface pairing properties which enable a noise-free and lubrication-free mutual pivoting, as a result of which even with a large number of movements in practically no wear and tear and no noise occurs during recording. Advantageously, at least one guide section radially projects from the pin section, which is intended to guide the holding rod or to come into contact with a surface of the holding rod, the holding rod on its corresponding side being optionally designed with or without latching depressions. For this purpose, the guide section preferably has a rounded contour which, even when pivoted about the pin section, enables the holding rod to be touched along a line, at least outside of latching positions. Alternatively, it is possible to provide a bearing in the guide section in which a roller is rotatably mounted, the roller then interacting with the holding rod with at least part of its surface. The roller is preferably made of plastic or metal and has coaxially arranged cylinder sections which are rotatably held in corresponding bearing recesses, while the circumferential surface of the roller maintains a distance from the guide section of the oscillating element. Alternatively, pin sections of the guide section can engage in corresponding bores in the end face of the roller and support them in this way.
The vibrating element is made of a hard plastic and rigid, so that the vibrating element can be rotated about an axis without being itself bent. As a result, the oscillating element can apply the force applied by the torsion spring to the narrow side of the holding rod, the winding axis of the torsion spring and the pivot axis of the pivot element preferably coinciding. In addition, the hard plastic of the vibrating element prevents a groove from being buried in by the sliding rod.

A region of the Swinging element through the spring member in the direction of the support rod acts, whereby the bias of the guide portion and thus the Appropriate locking force initiated for the detection of a motor vehicle door become. According to a preferred embodiment of the invention, this applies Spring member, for example one provided between two winding sections Suspension fork of a torsion spring, on the guide section of the vibrating element on the side facing away from the support rod, the Distance to the pivot axis of the vibrating element, the lever arm by the Defined spring initiated force. Alternatively, it is possible to use the spring member on one in the manner of a one projecting rigidly from the cylinder section another guide section to attack, which causes the bias of the spring member via the further guide section and the pin section is transferred to the first guide section. Alternatively, it is further possible resilient or preloading parts in the pin section of the Introduce vibrating element and via this the bias of the vibrating element make. This possibility is e.g. cheap when the in the parts penetrating the pin section with one to be attached later Interact cover part or the like. It is advantageously possible to use the oscillating element with the load arm of the spring member, e.g. the suspension fork one Torsion spring to be formed in one piece, e.g. by inserting it into the injection mold, and then insert it together in the housing of the door arrester.

The spring member is preferably designed as a torsion spring, at least has two winding sections, each in a recess of the first Housing part are supported circumferentially, preferably one with the Vibrating element engaging suspension fork the two winding sections connects together and the two ends of the suspension fork facing away from the Winding sections as the bracing against parts of the housing Build up tension of the torsion spring. Due to the circumferential absorption the winding section is not required to have a pin passing through it to provide, but it is possible, nevertheless, cores, preferably from one Light material, in each case in one of the winding sections to store the Reduce torsional stress on the winding sections or alternatively even to arrange a continuous bearing pin in such a way that this also Pen portion of the vibrating element penetrates, the two parts Bearing pin and vibrating element are arranged rotatably to each other. In In this case, a peripheral bearing of the vibrating element is not additional required. Alternatively, the cores can be used as extensions of the Pin portion of the vibrating element can be equipped. Preferably however, the winding section was not filled at all. Alternatively, it is it is also possible to provide two stubs, both of which, if necessary engage at least partially in the pin portion of the vibrating element and thereby fix it both axially and pivotally. This Embodiment can preferably also by driving the pin stub through the housing and possibly through the winding sections from the outside respectively. The turns of the winding sections are preferably spaced apart wrapped to avoid noise.

A preferred development of the cores is that they are circumferential are provided at least in sections with at least one groove, in the adjacent turns of the groove by a radially projecting web are limited, wherein the groove is preferably helical on the circumference of the Kerns is provided. The cores expediently have in the region of the Is a certain oversize to the inside diameter of a turn of the Spring member on, so that the projecting webs adjacent turns of the Push the winding sections of the spring link apart. Then it is possible screw the cores into the winding section, the windings of the Spring member are forced into the groove and through the protruding webs of the core are spaced apart. This will be advantageous at Operation of the spring member resulting squeaking noises by rubbing Avoid adjacent turns of the spring member. Alternatively to Screwing in it is possible to inject the cores into the winding section. It is possible that, for reasons of weight saving, the cores are hollow Cores are formed.

According to a preferred embodiment of the invention, the housing one with respect to the support rod a guide portion of the Control cam arranged opposite the oscillating element, which preferably engages in recesses provided in the holding rod and this is firmly connected to the housing. The control cam is preferably designed as a one-piece elevation in the housing, for example by Manufactured by injection molding, which engages with the support rod circumferential area of the control cam coming from a firmer material than the rest of the housing can be formed. A particular advantage of Control cam is that this not only in the direction of movement Handrail rounded, but can also be slightly curved transversely to this, whereby only one point of contact is provided instead of a line of contact is. Alternatively, the control cam can be a central plate Have flattening, which increased friction and thus increased Represents braking resistor for the handrail. By designing the in The cam protruding towards the handrail will be the annoying Squeaking noises caused by the metal roller previously provided at this point generated, advantageously avoided. In one configuration of the housing in plastic injection molding, the cam can be stable with little Material costs are designed and does not require stabilized Edge tabs on which a shaft for a rotatable roller is otherwise stored must become.

According to a preferred embodiment of the invention, the door arrester a stop damper on the opening for a handrail limited, the shock absorber impacting one on the handrail trained stop softens in the end region of the passage opening and in the last shift section when a car door is opened brakes and at the same time dampens the impact sound. The stop damper can be integrally formed with the housing, or as a mounting part be clipped or screwed to the housing. Preferably, the Stop damper a circumferential plastic frame in which those in the Usually arranged opposite on two sides of the passage opening Lots that come into contact with the stop of the handrail to Damping are formed. By providing the surrounding scaffold, which is preferably formed in one piece with the housing, at one Metal housing but also by a clipped plastic part, which in the Injection molding process was made, can be ensured that even with non-uniform loading, e.g. if the stop on one side, in particular facing the pivot axis of a motor vehicle door, occurs unilaterally, however the load is evenly absorbed and sustainably dampened even after a large number of braking operations. The design as a part separable from the housing has the advantage that the stop damper can be designed as an inexpensive wear part, which when the damping function weakens against an identical, Spare part can be exchanged.

According to a first preferred embodiment of a shock absorber this comprises a compressible elastomer body which consists of a an inner restoring force is provided elastomer material and is compressible to dampen the impact to the impact energy in convert elastic deformation. The impact on an elastomer body which is, for example, a polyurethane foam strip can, can be inexpensively by overmolding in a shock absorber Insert plastic without slipping under the sun Adhesive surface of the elastomer body takes place. Furthermore, the elastomer body also an inner deformation that does not result from evasion into others the stop of the handrail allows loaded areas and thereby one enables effective braking.

The at least one elastomer body preferably projects above the forehead region in front of the passage opening and thus defines a protruding area above the forehead area Braking area in which the impact energy into elastic deformation energy of the elastomer body is converted until the elastomer body surrounding area is reached, which optionally has an end stop defined or in turn according to another, e.g. one below compliant to the transformation into deformation energy can be trained. There is preferably one elastomer body strip each arranged mirror-symmetrically on both sides of the passage opening, so that at a two-wing stopper on the handrail of each of the wings of an elastomer body is braked.

A further preferred embodiment of the impact damper is provided with the housing or the frame of the shock absorber in one piece molded on guide element in front, which via a deformable connection or its own deformable configuration in its relative position and Design to the housing is changeable, being in the initial design the stop damper is biased towards a raised position or is relaxed. The passage opening is expedient on both sides mirror-symmetrically one guide element each arranged on a common scaffold that can also be integrally formed with the housing can be arranged, whereby the two guide elements each one the wing of the stop can be assigned to the handrail. It understands yourself that the guide elements themselves with a protruding described elastomer body can be equipped.

According to a first preferred development, the guide element is in a recess of a wall of the passage opening arranged and against a floor provided there can be struck, the guide element over at least two, absorbing a primary deformation energy Connections connected to the wall. These connections are preferably plastic webs that have sufficient thickness to prevent tearing are secured, but at the same time allow preferred elastic deformation, whereby the stop area of the guide element defined between the webs is shiftable towards the floor. The connection can also be provided unilaterally, in which case, however, it comes under the load of the stop to buckle and the floor in the wall defined then the end stop of the stop of the handrail. With a bilateral In contrast, the connection element becomes the guide element in the direction of movement Handrail shifted, and there is an indirect stop of the handrail to the floor through the intermediate guide element is buffered. For this purpose, the guide element in its Impact area be thickened like a lens, whereby by pressing the lenticular body to the ground by the pressure of the stop of the Holding rod the lens is flattened and undergoes an elastic change in shape temporary material shift occurs so that the impact absorbing Effect through the elastic change in shape of the lenticular body and accordingly the energy conversion is further supported. It is possible, for this purpose one only towards the floor or towards the stop To provide directed lenticular bulge, alternatively, both Directions are provided a dome-like shape. It is further possible to provide the lenticular body with a cavity that a additional flattening of the lenticular body when pressurized allows and thereby allows even more deformation. In this case it is lenticular body designed as a bubble. By shaping the as Deformation body designed guide element can have a damping characteristic be defined via the impact path, which is of different steepness and in adaptation to desired noise development and others damping properties as well as adapting to the weight of the door can be optimized.

A further preferred development of the impact damper is seen Guide element in front, which via a resilient foldable connection in a raised position is displaceable by the impact of the attack Handrail in a lowered position while storing energy can be pushed back, whereby to tension the resilient connection a corresponding conversion of the impact energy occurs and the impact is thereby dampened. Again, it is possible to use the guide element To combine damping means of the type described above, for example by design as a lenticular body or by provide elastomer dampers either on one or both sides of the To dampen the guide body in addition. It is also possible that To design the damping element as a scaffold that can be placed independently on a housing, that at least partially delimits the passage opening and thus provides effective damping even with a metal housing.

10 shows in perspective the housing 3 for the door arrester according to FIG. 1 or Fig. 7.

Fig. 11 shows an alternative embodiment of a housing 3 ', which consists exclusively of a first housing part 4, and without a cover or second housing part is formed. For better illustration, they are Torsion spring 14 and the vibrating element 15 not shown. Here is the Spring support 26 integrally formed with the first housing part 4 by for example as a laterally projecting web with the wall of the first Housing part 4 is connected. It can be seen that the lower, the door assembly part facing area of the first housing part 4 essentially remains open so that the torsion spring 14 and not shown here Oscillating element 15 can be used, parts of the cover 5 from FIG. 1 through plastic walls produced in one piece with the first housing part 4 are replaceable. This may require that To provide injection molding process with removable cores in several steps.

12 to 14 show a further alternative exemplary embodiment for a Housing 3 ", in which the only housing part 4 here essentially as the door assembly part is designed cover part, during which the Control cam 21 spanning area remains free and thus a Door arrangement part facing away opening for the insertion of spring member 14 and has oscillating element 15.

15 and 16, another preferred embodiment is one door arrester according to the invention 1 "shown, the structure in essentially corresponds to that of FIGS. 1 to 5 and in the the same reference numerals therefore the same or functionally comparable parts describe. So essentially the following is the differences Referred.

The door arrester 1 "also has a housing 3 with a first housing part 4 and a second housing part 5 designed as a lid, further a Vibrating element 15, which in one of the ways described above can be trained. In corresponding recesses 16a, 16b of the first Housing part 4 is a torsion spring 14 "with its winding sections 14a", 14b ", whose suspension fork 14c is against the oscillating element 15 supports and whose ends 14d ", 14e" facing away from the suspension fork 14c Winding sections 14a ", 14b" are supported on corresponding spring supports 26 are. The winding sections 14a ", 14b" of the torsion spring 14 "are such Distance wound that the turns arranged adjacent to each other have a distance from one another which is approximately the diameter of the Spring wire or the width of a turn corresponds. This is ensures that when tensioning and relaxing the torsion spring 14 "no Squeaking noises caused by rubbing adjacent turns arise. For this purpose, it is advantageously possible to use the winding sections 14a ", 14b" to wrap at a distance, whereby the torsion spring 14 already at Insert is designed to be correspondingly quiet.

In the present case, the first housing part 4 also has in the area of Recesses 16a, 16b a groove-like, screw-shaped Profiling on that in the concave area where the winding sections 14a ", 14b" are encompassed circumferentially, grooves 30 are defined for the windings, which are adapted to the diameter of the windings and in the areas in which there are gaps between adjacent turns, one have protruding web 31, which in relation to the bottom of the groove 30th is slightly higher than half the thickness of the wire of the torsion spring and so keeps adjacent windings at a distance. This makes it special reliably ensured that even with particularly unfavorable Stresses of the door arrester 1 "no noise from the mutual rubbing of the turns arises. If in the cavities of the Winding sections 14a ", 14b" cores can also be used be provided with a recessed groove for receiving the Windings and with a ridge between raised to separate neighboring windings.

15 and 16 that the winding sections 14a ", 14b" are present are wound three times, and correspondingly two web areas 31 in the direction of protrude the inside of the first housing part 4. In the area of the webs 31 is the outer side of the first, as can be seen particularly in FIG. 16 Housing part 4, which consists of plastic and injection molding is made, retracted, which gives a particularly characteristic and aesthetically pleasing housing design results.

Referring to Figs. 17 through 19, another is preferred Exemplary embodiment of a door arrester described in the area of the passage opening 7 of the housing 3 for a (not shown) support rod with a total 40 designated stop damper, which the stop 8 of the Holding rod 2 facing end face of the passage opening 7 against the Noise when hitting the stop 8 and against ensures unintentional rebound.

In the present case, the stop damper 40 is in one piece with the first housing part 4 injection molded, but it is possible to use the shock absorber 40 in a separate part of the scaffold with a corresponding Housing of a door arrester, optionally also made of metal or in conventional base plate design connected in a suitable manner is, for example by gluing, soldering, welding, clipping, Screwing, joining or the like.

In the exemplary embodiment according to FIGS. 17 to 19, the stop damper comprises 40 two strip-shaped and parallel to each other, mirror image of Halving the passage opening 7 arranged and in the manufacture of first housing part 4 already injected and thus firmly in the material of the first housing part 4 inserted elastomer body strips 41, which with about half of its height (see FIG. 19) over the end face of the passage opening 7 protrude and thus before hitting the face of the passage opening 7 an elastically deformable resistance for the stop 8 of the Form handrail 2. When the two wings of the stop 8 hit the Handrail 2 on the elastomer body 41, these are under the load of Stop deformed in the areas protruding from the end face, whereby due to the design of the elastomer body, for example Polyurethane foam or the like, a reversible displacement or Dodging of the elastomer body strips 41 takes place, which is due to the Toughness of the material absorbs considerable deformation energy and thus dampens the force of an impact and its noise accordingly.

Due to the firm anchoring of the elastomer strips 41 in the side walls 23 of the passage opening 7 is at the same time ensured that when the sun is shining or other temperature stress a migration of the elastomer strips and thus deactivating the cushioning is avoided. It can be seen in particular in Fig. 17 that the plan rectangular elastomer strips 41 from all four sides in the area of their lower half are surrounded by the plastic material of the walls 23 and also bevelled corners in the area of their protruding half or have edges so that the mechanical stress in these Areas is reduced from the outset.

Another embodiment of a door arrester with one opposite 17 to 19 modified stop damper 40 'results from 20 to 22, in which the same reference numerals as in the previous embodiments denote the same or functionally comparable parts.

Here too, the first housing part 4 of the housing 3 is made of plastic Injection molding process, wherein in the side walls 23 which the Passage opening 7 for a support rod 2 with its stop 8 laterally limit, a guide element 42 is formed, which is in the area of impact of the Stop 8 approximately flush with the end face of the passage opening 7 flat top 42a. The underside facing away from the upper side 42a 42b of the guide element 42 is rounded downward and points spherically on a floor 43 which is formed in the wall 23. The guide element 42 is on both sides with the wall 23 via flexible plastic webs 44 connected, which allow the guide element 42 a displacement path, in order for the underside 42b of the guide element 42 to strike the Allow floor 43. A first stop damping takes place through the Deformation of the webs 44, the lowering of the guide member 42nd enable. After the bottom 42b of the guide member 42 abuts has reached the bottom 43, the guide element 42 can under the action of the impact of the stop 8 still perform an elastic deformation such that instead of a line of contact between the bottom 43 and the bottom 42b, the guide element 42 is pressed flat, so that it becomes a flat Touch and power transmission comes. If the top 42a of the guide member is also crowned so that the guide element has a lenticular shape, can also be on the top 42a elastic deformation take place, the further impact energy in deformation energy converts and dampens the impact.

The impact damper 40 'has two opposite sides Guide element 42, each of the two guide elements 42 each a wing of the stop 8 of the support rod 2 is assigned. It is possible, to form the wall 23 increased, thus taking into account the Path of displacement of the guide element 42 in the direction of the floor 43 the end stop dimension can be set like a rigid one trained wall 23.

A third exemplary embodiment of a stop damper 40 "is shown in FIGS 25, the same reference numerals as in the previous Embodiments the same or functionally comparable parts describe.

The stop damper 40 "is also in one piece with the first housing part 4 of the housing 3 is formed by injection molding, and has two as Stop bars 45 trained guide elements against which the wing of the stop 8. The stop bars 45 are double over two foldable, made of the same plastic as the housing part 4 and the strips 45 trained, biasing the strips 45 in a raised position Plastic springs 46 connected to the side walls.

The two strips 45 are symmetrical on both sides of the bisector the passage opening 7 and are also present in the present case via a Crossbar connected to each other, creating the system with the two springs 46 and the two strips 45 is mechanically coupled and also one one-sided load causes the tensioning of both springs 46.

When the stop 8 hits the two strips 45 through Folding the springs 46 towards an edge of the wall 23 prestressed, the impact energy due to the elastic change in shape is converted.

Above are three configurations of shock absorbers 40, 40 ', 40 " have been described, each with different mechanisms for damping to implement an impact. It is understood that two or more of the Embodiments described above advantageous with each other can be combined so that they together at one Stop dampers can be realized.

Above are three configurations of preferred stop dampers 40, 40 ', 40 "have been described, each in one piece with a first housing part 4 have been produced. It is understood that the described Stop damper also on a frame part defining a frame can be produced separately from the housing, and with any housing from Door stops can be combined.

The above exemplary embodiments have different configurations of vibrating elements 15 and control cams 21 described. It goes without saying that a particularly preferred embodiment of a door stay is excellent that both the control cam 21 and that Vibrating element 15 as sliding elements without additional moving parts Contact with the support rod are formed, regardless of the Design of the housing.

It goes without saying that also in the exemplary embodiments according to FIG. 11 or 12 the variants with rollers or rollers can also be used as in FIG. 7.

The invention has been described above with the aid of door locks, in which the housing 3 on the inside of a door arrangement part, especially a door handle. Because of the cheap acoustic and optical effects of the door arrester according to the invention can also be arranged on the outside of the door arrangement part become. In this case, the handrail 2 is inserted upside down
