DETAILED DESCRIPTION

(13) The door arrester shown in FIGS. 1 to 3 and designated overall by 1 is used to couple a door 2 of a motor vehicle, shown as a dash-dotted line, to a body 3, indicated as a dash-dotted line. The door 2 is connected to the body 3 via hinges, the door arrester 1 serving to brake the pivoting movement of the door 2 around the hinges and to limit the opening angle.

(14) The door arrester comprises a housing 20 having a central opening 21, which consists of two retaining portions 22, 23 made of plastics material that are plugged together, wherein the plastics material parts can be reinforced with metal reinforcement in particularly stressed regions. The opening 21 is enclosed by the upper housing part 22 and the lower housing part 23 when they are assembled, each of the two housing parts 22, 23 having an injected rivet bolt 24 which is provided for connection to the door 2 in its interior region.

(15) A door retainer rod 30 extends through the opening 21 and is coupled at a first end in the region of an axis A so as to be pivotable via a joint 31 to a mounting part 32 which has a recess 32a by means of which the mounting part 32 is attached to the body or a pillar of the body 3 can be connected by means of a connecting means such as a screw or a rivet. The joint 31 has an axis A which is parallel to the axis of the hinges, so that when the door 2 is opened, a pivoting movement about the axis A is initiated to compensate for the pivoting movement about the hinges.

(16) In its central region, the door retainer rod 30 has an elongate, slot-like through-hole 33 which is enclosed on all sides and which extends into the vicinity of the end 34 of the door retainer rod 30 opposite the joint 31. The door retainer rod 30 has a core 30a made of steel, which is enclosed by a casing 30b made of plastics material, as can be seen in particular in FIG. 3. The door retainer rod 30 has an upper, first side 35 which is formed with a profiling 35a, as will be explained below.

(17) In the region of the opening 21, the two housing parts 22, 23 have mutually engaging end regions which comprise projections 22a of the first housing part 22 which can penetrate into recesses 23a of the second housing part 23, as can be seen in FIG. 2.

(18) The first housing part 22 and the second housing part 23 are connected to one another by a guide pin 40, which also passes through the through-hole 33, by riveting the ends 41 of the guide pin 40 on an outwardly facing end face 22b, 23b of the first and second housing parts 22, 23. Through this, the guide pin 40 connects the two housing parts 22, 23 to one another to form a common housing 20.

(19) It can be seen that the second housing part 23 is made substantially from solid material and has a central bore 23c through which the guide pin 40 passes and is received largely without play.

(20) The first housing part 22 has, in the region of its end face 22b facing away from the door retainer rod 30, a short channel 22c which passes through the upper housing part 22 and which is adapted to the circumference of the guide pin 40. The channel 22c opens into a first cylindrical cavity 22d, which in turn merges into a second cylindrical cavity 22e with an even larger diameter, forming a step 22f. The second cylindrical cavity 22e is open towards the door retainer rod 30.

(21) A first braking element 50 and a spring member 60 formed as a helical spring loading the first braking element 50 are inserted into the cylindrical cavities 22d, 22e, the helical spring 60 being supported at one end in an annular recess on the back of the first braking element 50 and at the other end on the portion of the first cylindrical cavity 22d opposite the end face 22b, which radially surrounds the channel 22c. The spring member 60 is wound so that it can be compressed while increasing its preload. The spring member 60 also surrounds the guide pin 40 at a distance.

(22) The first braking element 50 has an end face 51 facing the door retainer rod 30, which has a slide elevation 51a protruding towards the door retainer rod 30 and running transversely to the direction of displacement of the door retainer rod 30, wherein the flanks thereof, which steadily fall on both sides, promote a sliding up and down movement of ramps of the profiling 35a. The first braking element 50 has a central boring 50c, which is formed to receive a cylindrical guide portion 40a of the guide pin 40 with very little play. The guide portion 40a of the guide pin 40 passes through the boring 50c and allows a movement of the braking element 50 towards the axis of the guide pin 40 and to pivot about the axis of the guide pin 40.

(23) The first braking element 50 comprises a portion formed as a perforated disk 52, which forms a circumferential edge 52a, and a central tube portion 53 which extends axially over the edge of the disk portion 52. The central boring 50c is formed in the tube portion 53 and also passes through the slide elevation 51a.

(24) It can be seen in particular in FIG. 3 that the step 22f forms a stop for the circumferential edge 52a of the first braking element 50, which limits the axial displacement. Alternatively, the end of the tube portion 53 facing away from the retainer rod 30 could also be used for this purpose.

(25) The second housing part 23 can have a plate spanning the width of the door retainer rod 30 and containing the bore 23c, which plate is intended to come into contact with a second side 36 of the door retainer rod 30 facing away from the first side 35. In this case, the guide pin 40 is guided through the central bore 23c. It is possible to design the plate as a common part with the second housing part 23.

(26) FIG. 4 is a portion of a modified door retainer rod 30′ which differs from the retainer rod 30 from FIGS. 1 to 3 in that a stop buffer 39′ is inserted in the through-hole 33 in the end region 34 of the retainer rod 30′ which is made of a soft plastics material. The stop buffer 39′ can either be injected into the door retainer rod 30′ or glued thereto. The stop buffer 39′ primarily serves to dampen any noise development when the end region 34 of the door retainer rod 30′ hits the guide pin 40 and, at the same time, serves to reduce the introduction of mechanical stresses into the plastics material casing 30b of the door retainer rod 30′ through direct mechanical contact.

(27) FIG. 5 shows an alternative embodiment of a door retainer rod 30″, which differs from the door retainer rod 30 from FIGS. 1 to 3 by the end region 34″ formed as a hammer head. The laterally protruding regions of the hammer head 34″ project laterally beyond the opening 21 of the retainer housing 20 and thus delimit the distance by which the retainer rod 30″ can be pulled out of the retainer housing 20. This also avoids the development of noise and mechanical stress in the region of the end of the through-hole 33.

(28) FIGS. 6 and 7 are a further preferred embodiment of a door arrester 101 according to the present disclosure, the same reference signs as in the embodiment according to FIGS. 1 to 3 denoting the same or structurally comparable parts.

(29) The door retainer rod 30, the first braking element 50 and the spring member 60 are unchanged according to the embodiment according to FIGS. 1 to 3. The door arrester 101 is not equipped with a retainer housing, however, but with two individual retaining portions 122, 123 which are of identical design and which are coupled to one another by a guide pin 140.

(30) The two retaining portions 122, 123 are each designed as angled profilings, with a substantially vertically extending leg formed with a recess 122k, 123k, which is used for fastening to a door 2, for example by means of corresponding rivet pins or screw bolts, and with a substantially plate-shaped horizontal leg which has a bore 122b, 123b through which the guide pin 140 can pass through. It can be seen that the guide pin 140 is a good deal shorter than the guide pin 40 from FIGS. 1 to 3 because it only has to connect the distance between the two horizontal legs of the retaining portions 122, 123. The guide pin 140 is riveted on the outside of the horizontal legs of the retainer portions 122, 123 and passes through the spring member 60, the central boring 50c of the first braking element 50, the elongate through-hole 33 of the door retainer rod 30, and a boring 70b of a further braking element 70, which rests on the horizontal leg of the second retaining portion 123. The further braking element 70 interacts with the second side 36 of the door retainer rod 30 facing away from the first side 35 to generate a braking torque against the displacement of the door 2. It can be seen that it is also possible to fasten the second retaining portion 123 rotated by 180 degrees on the door 2 and then to connect the further spring 60 and the first braking element 50 through which the guide pin 140 passes, which guide pin is longer, in particular when the second side 36 of the door retainer rod 30 is also equipped with a profiling.

(31) It can also be seen that the guide pin 140 connects the parts to one another as a whole, wherein the parts can each pivot about the guide pin 140. It is possible for the riveting of the ends 141 of the guide pin 140 to couple the retaining portions 122, 123 to the guide pin 140 in a non-rotatable manner.

(32) FIGS. 8 and 9 are a further preferred embodiment of a door arrester 201 according to the present disclosure, the same reference signs as in the embodiments according to FIGS. 1 to 5 denoting the same or structurally comparable parts.

(33) In contrast to the embodiment according to FIGS. 1 to 5, the guide pin 40 has a coating or casing made of PEEK450FE20 in the region of the guide portion 40a, which contacts the through-hole 33 of the door retainer rod 30, which promotes the sliding properties. It is possible to harden the region of the guide portion 40a alternatively by partial processing with a laser, so that the wear of this region, which is particularly stressed by relative movement, is reduced. Laser treatment and casing can also be combined.

(34) In contrast to the embodiment according to FIGS. 1 to 3, the door retainer rod 30 has a through-hole 33 which does not have an approximately constant width, but rather comprises regions of different widths. A free-running region 33F of the through-hole 33 has a width that is larger with respect to the circumference of the guide pin 40, so that a relative movement between the door retainer rod 30 and the guide pin 40 is practically unbraked or possible with minimal braking. This means that there is no need to exert increased force when the door is closed. This function is also referred to as a closing aid since the resistance of a lock has to be overcome in this region. A clamping region 33K of the through-hole 33 has a smaller width with respect to the circumference of the guide pin 40, so that a relative movement between the door retainer rod 30 and the guide pin 40 is braked and a greater force has to be introduced into the door to overcome it. In this way, it can advantageously be achieved that the door is braked shortly before it reaches its maximum opening angle, and accordingly less stress takes place when the stop 34″ is reached.

(35) In contrast to the embodiment according to FIGS. 1 to 3, the door retainer rod 30 has a retainer housing 20 which accommodates two spring members 60 and two braking elements 50, so that both the first side 35 and the second side 36 of the door retainer rod 30 are acted upon in each case by one of the braking elements 50. The braking elements 50 are in turn guided axially displaceably and rotatably via a central boring 50c on the guide pin 40.

(36) The retainer housing 20 comprises two plate-shaped retaining portions 22, 23, to each of which one end 41 of the guide pin 40 is riveted. The retaining portions 22, 23 are formed as sheet metal disks which absorb the force F (FIG. 9) introduced into the system by the spring members 60. It is possible to form the retaining portions 22, 23 also as plastics material disks.

(37) The retainer housing 20 further comprises a cover 25 made of plastics material, which is inserted between the two retaining portions 22, 23 and spaces them apart from one another. Since the cover 25 absorbs only small forces and also does not guide the braking element 50 radially, it is formed from a very thin-walled material and can be produced, for example, using an extrusion method. The spacing of the cover 25 from the braking element 50 allows the latter to rotate about the guide pin 40 when the latter follows the profiling of the door retainer rod 30. The opening 21 through which the door retainer rod 30 can be moved back and forth through the retainer housing 20 is also formed in the cover 25.

(38) The cover 25 comprises a central receptacle for the spring members 60 and the braking elements 50 as well as a guide 28 in which two link parts 80 are arranged, each having a sleeve 81 with an internal thread. The retainer housing 20 can be connected to a vehicle door via the sleeve 81.

(39) The two retaining portions 22, 23 can also be designed in such a way that they also completely or partially close the insertion openings of the guide 28. It can be seen that the cover 25 connects the two retaining portions 22, 23 and the parts coupled therewith indirectly to a motor vehicle part such as a vehicle door. It can also be seen that instead of a one-piece cover 25, this can also consist of two parts, a spring member 60 and braking element 50 being accommodated in such a part. Finally, it can be seen that although the cover 25 separates the retaining portions 22, 23, the cover 25 is not required for this purpose. The cover 25 thus above all protects the inner workings of the retainer housing against the ingress of contamination from the outside.

(40) The door arrester works as follows: the retaining portions 122, 123 or the housing parts 22, 23, which also form retaining portions, are connected to an interior region of the door 2, while the mounting part 32 is connected to the body 3. If the door 2 is now pivoted about the hinge axes with respect to the body 3, the door retainer rod 30 pivots about the axis 31 and is pulled out of the door 2, causing a relative displacement with respect to the first braking element 50. At the same time, the guide pin 40, 140 passing through the through-hole 33 secures the door retainer rod 30 in the region of its guide portion 40a, 140a. The first braking element 50 can also pivot about the guide pin 40, 140 in order to align its slide elevation 51a with the profiling 35a of the door retainer rod 30, the spring 60 loading the first braking element 40 with a preload so that it is pressed against the first side 35 of the door retainer rod 30. The preload of the spring member 60 is increased when the profiling 35 has an increasing thickness while the door retainer rod 30 is pulled out of the door 2. If the profiling 35a decreases, the spring member 60 is relieved again. As a result, the braking torque of the door arrester 1, 101 changes during the pulling out of the door retainer rod 30 from the door 2 as a result of the pivoting movement of the door 2. During the displacement movement of the door retainer rod 30, the door retainer rod is always centered by means of the guide pins 40, 140, so that there is no rubbing against the inner regions of the door 2 and/or against the boundaries of the opening 21.

(41) It can be seen that the door retainer rod 30 as a whole has an elongate course and thus differs from the known curved door retainer rods, which can rub against the opening 21. The elongate contour is made possible by the central guidance of the guide pin 40, 140 and leads to less material waste during the production. Furthermore, the door retainer rod 30 can be used in the same way for a left-opening door as for a right-opening door of a motor vehicle whose braking force characteristics do not differ, because the curvature no longer determines the installation location on the left or on the right. It can also be seen that the door arrester 1, 101 can be installed on both sides of the vehicle, for example by rotating it by 180 degrees. That is, the first side 35 points upwards for one side and downwards for the other side.

(42) FIG. 10 shows the door arrester 101 from FIG. 7 in a modified variant, the same reference signs as in FIGS. 6 and 7 denoting the same parts. In contrast to the door arrester 101 from FIG. 6, the braking element 50, which is freely axially displaceable and freely rotatably connected to the guide pin 140, has a radially extending nose 250 which projects radially perpendicular to the extension of the slide elevation 51a and protrudes in a sword-like manner into the through-hole 33 of the door retainer rod 30, and thus aligns the braking element 50 with respect to the profiling 35a. In this case, the nose 250 also protrudes axially a little beyond the slide elevation 51a, so that in every axial displacement position of the braking element 50, the nose 250 penetrates a little bit into the through-hole 33, even if the first side 35 is substantially flat. The nose 250 assists the braking element 50 in following the rotation of the door retainer rod 30 about its articulation 31 by transmitting a stronger torque to the nose 250 and thus to the braking element 50. The nose 250 is formed in this case with two parallel surfaces, which can be introduced into the through-hole 33 with little play, so that there is no undesired additional braking. However, it is possible to design the two surfaces in a wedge shape in the radial direction and/or in a wedge shape in the axial direction in order to support centering during the movement.

(43) It is also possible, instead of a nose, to provide a different projection on the braking element 50 which penetrates into the through-hole 33, for example a cylindrical pin which is spaced radially from the axis of the braking element 50 and provides the same function. An angled pin or a pin protruding obliquely from the braking element 50 is also possible.

(44) The pin 250′ can alternatively also be provided as an extension of the tube portion 53 of the braking element 50′ or as an extension of the tube portion 53, and thereby completely or partially surround the guide pin 40 within the through-hole 33.

(45) If the door arrester has two axially displaceable braking elements 50, both are expediently equipped with a projection 250. In this case, the two projections can also be attached in opposite directions, so that one projects radially in the opening direction and the other radially in the closing direction. If the two projections are arranged in the same direction, in particular in alignment with one another, they are dimensioned in such a way that they do not touch, or at most touch one another in the region of the door being pulled shut.

(46) The further braking element 70 also has two projections 270 which penetrate the through-hole 33 of the door retainer rod 30 in the manner of a nose or a sword with the advantages mentioned above.

(47) It is possible to equip only the braking element 70, which cannot be axially displaced, with the projections 270 and to dispense with the projection 250 on the first braking element 50.

(48) It is also possible to arrange two radial projections 250 on the braking element 50 so that the braking element 50 is centered in both directions of movement along the profiling 35a.

(49) The projections 250, 270 are expediently formed in one piece with the respective braking elements 50, 70, in particular made from plastics material in an injection molding process. However, it is also possible to inject a metallic projection or to screw it in or to secure it in some other way after the production of the braking element 50, 70.

(50) The projections provided on the braking elements and their centering in the through-hole 33 also prevent friction of the guide pin 40 on the inner walls of the through-hole 33, which leads to less wear and/or corrosion, and less noise. For this purpose, the thickness of the projections 250, 270 is expediently greater than the diameter of the guide pin 40, at least in the region in which it passes through the through-hole 33.

(51) It is possible to select the wedge shape or taper of the projections 250, 270 such that an increased friction torque is provided in specific regions, for example by the through-hole 33 providing constrictions in specific regions in which the projections 250, 270 experience an increased friction during displacement along the profiling 35.

(52) The present disclosure has been explained above on the basis of embodiments in which the first side 35 of the door retainer rod 30 points upwards. It has to be understood that the first side of the door retainer rod can also be inserted into the vehicle in such a way that it points downwards and the first braking element 50 presses against the first side 35 from below.

(53) The present disclosure has been explained above on the basis of an embodiment in which the retaining portions 22, 23 are parts of a retainer housing 20 which delimits an opening 21 for the passage of the door retainer rod 30. It has to be understood that a retainer housing, which laterally delimits the door retainer rod 30, is no longer required if the guide pin 40, 140 passes through the door retainer rod in the region of its central through-hole 33 because in this case an edge-side guidance of the door retainer rod 30 is not necessary.

(54) The present disclosure has been explained above on the basis of embodiments in which only a first side 35 of the door retainer rod 30 is acted upon by a first braking element 50. It has to be understood that door retainer rods can also have two sides, each of which is acted upon by a braking element 50 for generating a braking torque.

(55) The present disclosure has been explained above on the basis of an embodiment in which the guide pin 40, 140 is connected to the retaining portions 22, 23, 122, 123 by riveting and thus connects them to one another. It has to be understood that there are also other possibilities for connecting the guide pin, in particular when the guide pin is equipped with threaded portions at the end, and that the spring force of the spring member 60 can also be finely adjusted as a result. In order to prevent an adjustment of the guide pin afterwards, the guide pin can be fixed to the retaining portions with a welding point or the like.

(56) The present disclosure has been explained above on the basis of an embodiment in which the elongate through-hole 33 of the door retainer rod 30 has a constant width. It has to be understood that constrictions or widenings can also be provided in the through-hole, which generate an additional braking torque when the door retainer rod 30 is moved relative to the guide pin 40, 140.

(57) A special feature of the door arrester 1, 101 according to the present disclosure is that the door retainer rod 30 and the first braking element 40 are both captively connected to the same guide pin 40, 140, which avoids an incorrect pairing of door retainer rod 30 and retainer housing 20 or retaining portions 122, 123.

(58) The present disclosure has been described above on the basis of a plurality of specific embodiments. It has to be understood that the individual elements of the embodiments, for example the retainer housing or the door retainer rod, can each be combined with the other elements of the other embodiments. Such combinations are expressly part of the subject matter of the present description.
