Abstract

A built-in ashtray has a housing (10) arranged on the vehicle, which defines a cut-out for the essentially rectilinear insertion of a sliding part (11). Two lateral guides (22 to 26) of the drawer part (11) are provided in the housing (10), together with a front stop which defines the pull-out movement of the drawer part (11). In order to ensure secure insertion of the drawer part (11) without tilting, with the smallest possible installation depth but at the same time the greatest possible opening travel, an ash container (13) is inserted into the drawer part (11) as a removable dish. A third guide (20, 21) is arranged on the underside of the drawer part (11) to the housing (10). In the extracted position, the drawer part (11) is fixed by a single first detent spring (50), which acts approximately in the centre on the upper or lower side of the drawer part (11) between this and the housing (10). <IMAGE>

Description

Built-in ashtrays for automobiles

The invention relates to a built-in ashtray for motor vehicles with a housing arranged on the vehicle, the housing walls having a Cutout for the essentially straight insertion of a sliding part with too limit the housing walls essentially parallel sliding part walls, with an ash container, which by means of a in the area of a front handle the thrust part arranged and manually operable detent spring from the housing solvable is, with two lateral guides of the sliding part in the housing and with a front one Stop that limits the pull-out movement of the thrust part.

Such an ashtray is the subject of the not previously published German patent application P 74 09 732.5.

This early ashtray has the drawer part and the ashtray one-piece, i.e. both functions are taken over by a container that is on the side is provided with appropriate guides and made of a refractory material inside consists. Ashtrays of this type, pushed essentially in a straight line, are usually referred to as "Schubascher" as opposed to "swivel ashtrays, in which the movement consists essentially in a pivoting about an axis. Generally will Push ashtray built into a dashboard, while swivel ashtray either underneath the dashboard or in the doors of the motor vehicle.

In the development of built-in ashtrays for motor vehicles exist increasingly conflicting demands. On the one hand there is the requirement to make such ashtrays as comfortable as possible, i.e.

tilting, jamming or the like. safe to prevent at the same time but with the lowest possible actuation forces a secure fixation in the inserted and to ensure the extended position. Furthermore, there is a desire to make the ashtray as complex as possible, especially a lighter for Incorporate cigarettes or cigars into the ashtray so that it is pushed in Ashtray is not visible from the outside. This contradicts this, however from the motor vehicle manufacturers mostly raised demand that Installation dimensions, in particular the installation depth, of such ashtrays to a minimum to reduce.

The invention is therefore based on the object of a built-in ashtray of the type mentioned to the effect that despite the low installation depth a large opening stroke as well as a safe and tilt-free guidance guaranteed and that it is still possible to integrate a lighter into the ashtray is.

This object is achieved according to the invention in that in the drawer-like trained push part used at least the ash container as a removable shell is that a third guide is arranged on the underside of the thrust part to the housing is and that the thrust part is in the withdrawn position by a single first The detent spring is fixed approximately in the middle between the side guides the top or bottom of the thrust part acts between this and the housing.

These measures completely solve the problem on which the invention is based, because first of all the provision of a sliding part that is usually not removable with inserted, removable ash container considerably more freedom in the Ashtray construction leaves. The sliding part and the housing can perfectly made of plastic and the necessary guides without too much effort can be realized with high precision. In addition, such a plastic part The space required for a lighter can be provided with little effort, whereby the possibilities mentioned in detail below result, the lighter for easy removal while pulling out the To swivel the ashtray up into a removal position.

The third guide on the underside of the sliding part carries on helps to achieve safe guidance despite the shallow installation depth, because the additional guide on the underside tilting at an angle to the direction of insertion prevented.

The detent spring ensures that the ashtray is in the pulled out position Position is fixed, so not by vehicle vibrations or the like. to solve can. This is also particularly advantageous because the improvements to the Leadership, i.e. the ease of movement of the ashtray, could lead to the ashtray moved unintentionally due to vibrations.

By providing a single such detent spring is finally ensures that only a single pressure point when inserting the ashtray is to be overcome, the arrangement of the detent spring approximately in the middle of the handle ensures that this pressure point is overcome without tilting, regardless of whether the user presses the handle in the middle or from the side.

Although it is from an ashtray that the applicant sells, known, a normally not removable sliding part with a removable one To use ash container, but this is known ashtray around one whose movement runs essentially around a pivot axis and the one below a dashboard is installed. Due to the relatively long available guideway the problems mentioned at the beginning do not arise. The well-known ashtray is also provided with two locking springs that act on the side edges of the pushing part. However, this concept cannot be applied to the ashtray of the present invention will. In the case of a drawer ashtray with an essentially straight insertion movement and high-quality guiding would be given with lateral pressure on the handle first of all, the pressure point of the detent spring on one side must be overcome and become then tilt the ashtray because the pressure point of the opposite one is overcome Detent spring from this side is very difficult to achieve. It would therefore be a significant one Effort required to close such an ashtray, one Property that is not accepted, especially in high-quality vehicles.

In contrast to the well-known ashtray and the one in the opening mentioned earlier patent application P 34 09 732.5 described ashtray the ashtray according to the invention therefore has, in summary, the advantage that at minimum depth dimensions a large opening stroke is possible, with the ashtray is fixed in the pulled out position and can be closed well after use, regardless of whether the user is on the side or in the middle of the handle presses.

In one embodiment of the invention, for example, a built-in ashtray realized due to the special circumstances of the Motor vehicles :; had a - seen from above - trapezoidal plan shape, their Installation depth on one side was 62 mm and on the other side 92 mm, despite the minimal depth of 62 mm, however, enabled an opening stroke of approx. 50 mm.

In a further embodiment of the invention for installation in a The dashboard of the motor vehicle is provided that the first detent spring from the Center is arranged offset in the direction of the driver's seat.

The advantage of this embodiment is that the ashtray is on the side can be offset by the driver, for example in the middle of the dashboard or even something beyond that if the part of the dashboard is in the area of the driver is required for extensive instrumentation. The driver will then usually laterally offset on the handle when closing the ashtray press so that in this embodiment of the invention he is at one point will press the handle that is aligned with the detent spring. This will make the The risk of tilting is further reduced.

In a further embodiment of the invention, the ash container is running in guides of the thrust part, which are essentially parallel to the lateral guides of the thrust part run on the housing, and the ash container is in one of the Push part inserted position fixed by means of a second detent spring.

This measure has the advantage that a regulated removal of the ash container is possible. If the ash container were only fixed by a clamping spring, the pall could happen that when the ash container is pushed out, this is due to its light weight, even when full, pops out and the contents the ash container is scattered inside the vehicle. The guides of the ashtray according to the present invention, on the other hand, ensure that even after overcoming of the pressure point of the second detent spring first measure a guided movement must be, during which an acceleration of the movement that may have occurred Overcoming the pressure point of the second detent spring can be caught again. The ash container can thus be safely removed and there is a risk of it being scattered the contents of the container does not exist.

Another development of this embodiment with a second detent spring is characterized in that the second detent spring on the underside of a raised The bottom area of the ash container is arranged and when it is pushed into the housing Push part lies within the outline of the housing.

This measure initially has the advantage that the second detent spring with normal use of the ashtray does not bother at all because it is underneath of the bottom area of the ash container is not visible. The arrangement within the outline of the housing with the ashtray inserted has the advantage that when Pulling out the ashtray for normal use does not use the second detent spring can be accidentally released so that there is no danger to the user accidentally took the ashtray instead of the push part pulls out. Rather, the thrust part must first be pulled out before a deepened one Handle on the underside of the sliding part of the ash container can be released.

In a further embodiment of the invention are in the push part Furthermore, a holder for a lighter and means that a pivoting movement the holder cause upward when pulling out the thrust part, arranged.

These measures take advantage of the fact that the separation the functions of the drawer part and the ash container considerably more freedom Construction offers, which has the advantage that additional components can be integrated into the ashtray. The lighter is in this embodiment When the ashtray is inserted, it is not visible from the outside and therefore does not interfere visually, it still protrudes from the dashboard and can therefore also be used in the event of an accident do not represent a hazard. Due to the intended pivoting movement of the bracket it is possible to lay out the ashtray relatively flat and still use the lighter easy to remove because the holder only opens when the ashtray is pulled out swivels upwards, making the lighter easy to remove.

This also serves traffic safety because the attention of the Driver is not required to use a lighter that is fixedly arranged in the thrust part To have to pull out "with pointed fingers".

In a preferred embodiment of this embodiment has the push part has a middle push part wall running parallel to the push part walls that separates the ash box from the holder, and the holder is by means of two lateral pins in one of the sliding part walls and in the middle one Sliding part wall rotatably mounted.

This embodiment has the advantage that the pivoting movement with particularly simple means is realized, and the assembly is very simple, because the sliding part walls, which are generally made of plastic, to a certain extent are elastic and the bracket with the side pins therefore easily in corresponding Location bores of the sliding part walls can be clipped.

In a further embodiment of the above-mentioned embodiment the holder is rotatable about a preferably horizontal axis, it is also provided with a sliding pin arranged outside the axis, and in the housing a groove running at an angle to the direction of insertion is provided in which the Sliding pin runs.

This embodiment is a very simple way to such as the pivoting movement, for example by the pin mentioned above is made possible, can be effected. Due to the location and shape of the groove the pivoting movement of the bracket can then be easily adapted depending on the installation conditions will.

Further advantages emerge from the description of the enclosed Drawing.

An exemplary embodiment of the invention is shown in the drawing and is explained in more detail in the following description. Show it: Fig. 1 shows a side section through an embodiment of an inventive Built-in ashtray; Fig. 2 is a section in depth, along the line II-II of Figure 1; Fig. 3 is a section in depth, along the line III-III of Figure 1; 4 shows a section in depth, namely along the line IV-IV of Figure 1; Fig. 5 is a side view of the embodiment of Fig. 1, seen from the left; 6a and 6b show a section in depth, and although along the line VI-VI of Fig. 1 in the inserted state (Fig. 6a) and in the pulled-out state (Fig. 6b) of a push part.

In Fig. 1, 10 denotes as a whole a housing of an embodiment a built-in ashtray according to the invention, which is not shown in detail in FIG Fastening means, for example flanges, eyes and the like. In or on a dashboard a motor vehicle can be attached. In the housing 10 is in the direction perpendicular a drawer-like sliding part 11 can be inserted into the plane of the drawing in FIG. That Push part 11 has a first area 12 for receiving an ash container 13 and a second area 14 in which a holder 15 for a lighter is arranged. Housing 10 and push part 11 are made of plastic.

The push part 11 is of a left push part wall 16 and one right thrust part wall 17 limited. These sliding part walls 16, 17 run essentially parallel to a corresponding left housing wall 18 and a right housing wall 19th

The push part 11 runs in the housing 10 by means of three tongue and groove guides. The first guide is arranged in the floor area and consists of a first, middle one Spring 20 of the thrust part 11 and an associated first, central groove 21 of the Housing 10. There is a second guide in the area of the left sliding part wall 16 or the left housing wall 18 by a second left, lateral spring 22 of the thrust part 11 and a second left, lateral groove 23 of the housing 10. The course of the groove 23 is shown in detail in FIG.

The third guide is in the area of the right sliding part wall 17 or the right housing wall 19 and is partially rigid and partially elastic. In the right housing wall 19 are a third right, fixed spring 24 and fourth right, elastic spring 25 arranged, which is divided into several individual springs 25, 25a, 25b and 25c can be divided, as can be seen in detail in FIG. These Springs 24 and 25 act with a third right, double groove 26 of the thrust part 11 together.

One recognizes from the course of the second left lateral groove 23 in Fig. 4 and the third right, fixed spring 24 and the fourth right, elastic Springs 25 in Fig. 3, which define the insertion movement of the push part 11, that this insertion movement is essentially straight.

In FIGS. 1 and 4 one can also see a lens 30, which is arranged in the area of the left housing wall 18 and for lighting of the second area 14 provides.

For this purpose, a suitable space is placed in a cavity 31 in the lens 30 Luminous body or light guide used.

It can also be seen from Figs. 1 and 2 that the ash container 13 is guided in the thrust part 11. The ash container is on its upper side edges 13 namely provided with a flange 32 or 34, which is below guides 33 or 35 of a middle sliding part wall 27 which separates the areas 12 and 14 from one another separates, and the right thrust part wall 17 run.

The fixing or removal of the ash container 13 from the sliding part 11 becomes clear on the basis of FIG. 2 together with FIG. 1.

The ash container 13 has a raised bottom area 39 and a Front 40 to which a handle 41 is attached. Below the elevated Bottom area 39 is attached to this a first detent spring 42, for example riveted. The first detent spring 42 is bent in its central area and engages in the inserted state of the ash container 13 behind a projection 43 in the Bottom of the thrust part 11. The free end 44 of the first detent spring 42 projects outward before, but is in the inserted position shown in FIG of the thrust part 11 within the outline of the housing 10. This means that the User of the ashtray, who grips the handle 41 from below, the first Detent spring 42 cannot accidentally loosen. Only when the Push part 11, the free end 44 of the first detent spring 42 can pass through Pressure can be increased in the direction of arrow 45 so that the first detent spring 42 comes out from behind the projection 43 and the ash container 13 under the action of the guides 33, 35 can be pulled out towards the front. This movement essentially takes place parallel or in continuation of the pushing-in movement of the pushing part 11.

The processes when pulling out the thrust part 11 should now be based on 4, 5, 6a and 6b are explained: It can be seen from the side view of Fig. 5 that in the rear, lateral bottom area of the thrust part 11 is a projection 46 is arranged. The pushing-in movement and the pulling-out movement of the pushing part 11 are limited by a rear stop 47 and a front stop 49, which can be seen in FIG. The front stop 49 is located on two springs 48, 48a, which are arranged in the housing walls 18 and 19, respectively, as FIG. 1 shows. When assembling the ashtray, the sliding part 11 can accordingly be in the housing 10 are inserted, the front stops 49 sliding in during assembly of the thrust part 11 are pressed laterally outward by the projections 46 and then snap back behind the projection 49. The push part 11 is hereby caught within stops 47 and 49 and can with normal use of the ashtray cannot be pulled out.

To the thrust part 11 in the pulled-out position shown in Fig. 6b is shown to fix, a second detent spring is on the top of the thrust part 50, which can be seen in FIGS. 5, 6a and 6b. In the inserted State of the push part 11, which Fig. 6a shows, as well as during the pulling out of the push part 11, the free end of the second detent spring 50 rests or slides on the underside of the cover of the housing 10. Upon reaching the pulled-out position according to FIG. 6b, however, the free end of the second detent spring 50 engages in an opening 60 and fixes the push part 11 in this position.

As you can see the location of the sectional view of FIGS. 6a and 6b in the Line VI-VI of Fig. 1 can be found - in the front view of 1 seen - the second detent spring 50 approximately at the level of the middle thrust part wall 27. In this exemplary embodiment, there is therefore an optimal against tilting Secure insertion when the user is in this position on the handle 41 presses. This is readily guaranteed if a left-hand drive is used Motor vehicle out of the ashtray in the middle of the dash or something the center is offset to the right and the ashtray is essentially is used by the driver. In addition, in this embodiment, the ash container 13 be completely open at the top. However, it is also conceivable to use the second detent spring 50 to be arranged, for example, in the position of the line of the section II-II of FIG and there mechanically z.

B. to combine with a cigarette holder or a glow killer. However, it is important for the present invention that the latching only occurs on a single one Point occurs because then only a defined pressure point when inserting the sliding part 11 must be overcome.

Finally, the mechanism for pivoting is shown in FIGS. 4, 6a and 6b the holder 15 for a lighter to be seen.

The bracket 15 is provided with two lateral pins 51, 51a, those in the associated bores of the left sliding part wall 16 and the middle sliding part wall 27 are stored as from Pig. 1 can be seen. The location of the bracket 15 in a Direction perpendicular to the plane of the drawing in FIG. 1 with respect to the second region 14 the thrust part 11 is thus fixed. The thus enabled pivoting movement around the axis defined by the pins 51, 51a is effected by a sliding pin 52, which is arranged on a rearwardly facing flange 53 of the holder 15. Of the Guide pin 52 runs in a fourth groove 54 in the left housing wall 18, as in FIG individual Fig. 4 can be seen.

When pulling the thrust part 11 out of the position according to FIG. 6a In the position according to FIG. 6b, the pin 51 runs into a position 51 'along a first guide track 55, which is parallel to the second left, lateral groove 23 according to FIG Fig. 4 runs. In contrast, the sliding pin 52 runs along into a position 52 ' a second guide track 56 which is defined by the course of the fourth groove 54 is.

This relative movement of the pins 51 and the sliding pin 52 results in a pivoting movement of the holder 15 in the direction of arrow 47. The Bracket 15 swivels when pulling out the thrust part 11 accordingly upwards out of this and a lighter arranged in the holder 15 can easily can be taken from above.

It goes without saying that the pivot axis of the holder 15 is also perpendicular can be arranged to the plane of FIG. 1, so that the holder 15 does not is pivoted upward in the insertion direction, but rather transversely to it.

It is further understood that the above-mentioned in detail Guides, bearings and detents are also each carried out in a kinematic reversal can be by placing the grooves, tongues, locking springs, pins and tenons on each other Element are attached.
