Description

The invention relates to a device for temporary fixation in a Housing suspended suspended or held system, such as Drum bearing of a washing machine, consisting of holes in the system or rigidly connected approaches screw-in bolts, their respective shaft through openings in the housing, such as machine rear wall is passed through and their respective head is on the wall or on this (if necessary removable) supports stiffening profiles or crossbars, with between the inner surface of the wall or the stiffening profile or the cross member and the System a spacer sleeve penetrated by the shaft of the bolt is arranged, the device next to the spacer sleeve and the Screw bolts optionally one between the bolt head and the sleeve end face arranged positive locking device, the screw bolt having a Threaded first shaft area facing away from the bolt head with has a first (including the thread) diameter to which a second shaft area reaching to the head connects, which is not threaded having.  

Such a device is already known from DE 195 25 316 A1.

The known device in turn represents an improvement from the DE 42 15 780 A1 known arrangement. The known devices are used to Household machines, such as washing machines, against damage during transport protect where the tub is made of plastic. such Plastic materials have limited strength values and it is in tests found that the threaded domes of the tub made of plastic certain stress cases have been torn down. Furthermore, it has happened that at plastic deformation of a plastic sleeve between the rear wall of the Household appliance and the vibration system game emerged, which with more recent Stress led to the fact that the entire system no longer formed a unit and so occurring forces, especially vibrating forces, can no longer be adequately controlled were. The device according to DE 195 25 316 A1 already provides one significant improvement over DE 42 15 780 A1.

However, it has been shown that further improvements are possible. That's the way it is previously used screw bolt, which essentially represents a wood screw, with the length required here is relatively expensive and heavy. He also prepared his security within the facility for fixing the Swing system problems of a household machine, which led to it still happened that when dismantling the safety device Spacer from the bolt loosened and in the area between the rear wall and vibrating system (tub). As with the State of the art, this is of great disadvantage because of certain Washing machines, especially those known as aqua-stop devices have falling parts on the bottom formed by this aqua stop device get there and possibly to malfunctions and noise when Spin the machine. Because such machines always have a base plate are used more often, it is important that the device for fixing the vibrating system is designed so that such a separation between Bolts on the one hand and sleeves on the other hand never take place unintentionally  can. There are other areas where the same problem occurs, namely parts to be temporarily fixed within an enclosure without the later loosening loose parts in the housing, such as B. the spacer sleeve, remain.

The object of the invention is to provide a device for temporarily fixing a Suspended or suspended system of the type mentioned above to further develop that the assembly of the device even easier and It becomes "foolproof" and always takes place in such a way that when the facility is later dismantled from Z. B. the drum of a washing machine, the items of the device, that are in particular screw bolts, spacer sleeve and optional positive locking device stay together so that there is no risk that z. B. the spacer sleeve behind the back of the washing machine falls down and in an inaccessible place, how floor pan remains as a disturbing part.

The task is essentially solved in that the second shaft region unites second, smaller diameter compared to the first shaft region, and in that the spacer sleeve is close to the bolt head or optionally the Form-locking device adjacent end forms a transverse opening, in which / which a locking slide can be inserted and / or moved (claim 1).

This measure makes it possible to secure the screw bolt within the sleeve so securely to note that there is no risk that the two or the three components separate during dismantling work.

To ensure that the safety device in the Installed in such a way that the locking slide does not hold the bolt, According to a development of the invention, it is favorable if the Locking slide in its non-locking position over the outer cross section the sleeve protrudes (claim 2). The fitter is thus signaled that the The screw bolt has not yet been locked within the sleeve. Another The advantage is that the protrusion of the slide, the impression of this  Slider is facilitated. Yet another advantage is that with the appropriate Shape of the opening in the rear wall of the machine of the above Slider prevents the sleeve from sliding through the opening and thus the Fitter signals that something is still wrong here.

It has design advantages if the opening has a rectangular cross section (Claim 3), in particular also if, according to a further development, the Invention of the locking slide which can be inserted into the transverse opening in plan view U-shape, and if he with the inner surfaces of the legs of the U-shape Bolt shaft engages axially locking in the inserted position (claim 4).

According to yet another development of the invention, it is advantageous if the Locking slide on the outer surfaces of the legs of the U-shape a projection or forms a recess that matches a recess that protrudes into the two side walls of the opening lying parallel to the pin axis is arranged so that the locking slide in the bolt shaft encompassing position is fixed (claim 5). This has the advantage that the slide is in turn held in its locking position and thus one more greater security against the bolt falling out of the sleeve becomes.

Simplifying assembly while eliminating the risk of remaining Components for later disassembly is enlarged by the device for temporary fixation, as in the prior art, next to the spacer sleeve and the Screw bolt one more between the face of the sleeve and any existing one Compression spring arranged disc comprises, the disc at an edge region has an axially extending nose, which in a in the end face of the Spacer formed recess can penetrate when the bolt is attracted (claim 6). If the traverse or the like. A breakthrough for the Passage of bolt head and associated other components, such as washer, from which breakthrough at least one narrowed area at a distance from this one further breakthrough is provided such that it has at least one nose of the disc  can accommodate if the threaded bolt carrying the washer in or on Located at the end of the narrowed area, it is favorable that the washer on the Nose opposite edge area forms a breakthrough by one of the end face of the sleeve is penetrated in one piece 7).

It is advantageous if the opening for the slide is arranged so that it is transverse to the direction in which this edge region is arranged. The reason for this is that this results in a higher stability of the sleeve. In addition, the slide is then more accessible when using trusses. The stability is also increased if the recess is not in the area of the actual cross section of the sleeve is arranged as in the prior art, but on an outside of this Cross-sectional area, with the additional advantage that instead of a laterally open recess, as in the prior art, here on all sides enclosed recess can be provided.

This in turn enables a form of training in which (as in the prior art) the cross member or the like. An opening for the passage of the bolt head and associated other components, such as disc, of which breakthrough at least one narrowed area extends in the direction of the axis of the traverse or the like and can accommodate the cross section of the bolt shaft, and wherein on End of the narrowed area at a distance from this another breakthrough it is provided that he can accommodate at least one nose of the disc when the threaded bolt carrying the washer in or at the end of the narrowed area is located, according to the invention then the disc on that of the nose opposite edge area forms a breakthrough that is from one of the Sleeve end face is penetrated in one piece starting approach (claim 7). While two curved lugs must be provided in the prior art, In order to also achieve longitudinal stability, this is not necessary here. Continuing education is still possible so that the approach forms a barb that the disc secures against sliding off the heel (claim 8), namely holds it like a clip. This construction in turn has assembly advantages and gives greater security  against slipping of the disc from the sleeve. In addition, the Simplifying the metal disk simplifies the manufacturing process while at the sleeve to be molded from plastic with the production of such an approach Barbs are not a particular problem. Another point of view is that sometimes lay people do not know that e.g. B. the locking screws before start-up a household washing machine must be removed so that the drum z. B. can perform oscillating movements when spinning. It is therefore favorable to the To give users a hint that such locking screws are still are present and may need to be removed. This can be the case with a washing machine happen, for example, that the connecting cord of the machine only then can be plugged into an outlet when this fuse is removed have been. To achieve this, the approach of the Sleeve face at least one approach starts in one piece (claim 9) encompasses the cross section of a connecting cable for the household machine and holds (claim 10). If the user wants to put the machine into operation, he must first free this connecting cord, which is only possible by having the Security device removed. For greater stability, it can be beneficial if the further approach is supported by a hook extending from the disc (Claim 11). This further approach, which starts from the sleeve, can also be a perform an additional function by starting from the face of the sleeve Approach leaf spring shape and an approach formed by the disc, such as Hook, engages in such a way that the washer of the Sleeve end face is lifted (claim 12).

It is favorable if the approach of the sleeve face as well as that of the disc each exist twice and are arranged in such a way that between them extends into the recess of the sleeve end face penetration of the disc (Claim 13).

The stability is increased if according to a further embodiment of the End face of the sleeve in the direction of the leaf spring a reinforcing wall is provided (claim 14).  

The device according to the invention is not only for fixing the drum bearing a washing machine suitable, it can also be used in motor vehicle construction Temporary fastening of interior panels to body parts (claim 15) as in civil engineering for temporary fastening of insulation and Use cladding (claim 16).

The invention is explained in more detail by means of exemplary embodiments, which in the Drawings are shown.

It shows:

Fig. 9 is a partial view of the slide.

Fig. 1 shows a housing 10 , z. in the form of a washing machine, within which a vibrating system 12 , for example a spring-mounted tub of a drum machine can be seen, which tub 12 can be deflected with respect to the housing walls of the household machine due to its swinging suspension, in particular this occurs during rail transport if during maneuvering wagons loaded with such machines run onto other wagons. For this reason, the vibrating system, such as the tub 12 , must be fixed with respect to the housing walls of the machine during such transport.

According to FIG. 1, two cross members 14 are arranged on the back of the washing machine for this purpose, which are shown in FIG. 2 in a somewhat clearer manner. These cross members 14 are made of sheet steel and can be reinforced with reinforcing beads 16 , flanges 17 and the like. The cross member 14 is cranked at its two ends and on the one hand forms contact tabs 18 with which the cross member 14 can be placed on edge areas of the rear wall 20 of the household machine 10 , preferably in such a way that the cross member 14 in corresponding recesses by bending or indenting 22 or 25 or receiving areas that may be formed in the wall 20 for this purpose or that are present anyway. These give the cross members 14 a certain security against displacement parallel to the rear wall 20 . Instead of the crossbeams 14 , a welded-on plate can also be provided, just as the crossbeam 14 can also be permanently welded on. Threaded bolts 24 , one of which can be seen in FIG. 2, are with their shank through an opening 28 , 128 in the crossbeams 14 , on the other hand passed through a corresponding opening 26 in the rear wall 20 and screwed into a corresponding hole in the tub 12 or the like. In order to define a fixed distance between the outer surface of the tub 12 provided with the bore or threaded bore and that in the inner surface of the cross member 14 , a spacer sleeve 32 is used , which is located between the inner surface of the cross member 14 and the system 12 and on the shaft of the screw bolt 24 is arranged. If you tighten the screw 24 , the tub 12 is thus connected via the system of spacer sleeve 32 and screw bolt 24 to the crossmember 14 and from there via the contact tabs 18 to the (particularly stable) edge region of the rear wall 20 of the household machine 10 , z. B. by appropriate tensioning of the resilient suspension of the tub 12, a contact pressure can be transmitted to the cross member 14 and thus to the retaining tabs 18 , which connects these retaining tabs 18 sufficiently firmly to the rear wall 20 , so that, if necessary, special fastening devices, apart from a fuse against displacement, as already described, may be unnecessary.

At the site you will then unscrew the screws 24 from their holes in the tub 12 and together with the spacers 32 and z. B. Removable trusses 14 so that on the one hand the tub 12 or the other vibrating system can move freely, on the other hand the rear wall 20 is free of any projecting, no longer required holding devices.

Of course, if it is considered appropriate, the cross member 14 can also have its own attachment to the rear wall 20 , for example a special screw connection.

The opening 28 in the crossmember is expediently designed as a keyhole, as shown in FIG. 1, the larger area of the opening 28 being shaped such that the head 30 of the screw 24 fits through, but can subsequently be moved into the narrow area such that the Screw head 24 can no longer pass through the opening 28 . This makes it possible to first push the bolts 24 with the spacers 32 pushed on through the rear wall opening 26 and screw them into corresponding threaded bores or blind bores (if it is plastic) of the tub 12 , then z. B. the crossbar 14 on the rear wall, so that the screw heads 30 of the respective z. B. reach one or two screws through the corresponding openings 28 , and then move the cross member 14 so that the screw shafts get into the narrowed areas. Then the screws can then be tightened so that there is a clamping force between the screw head 30 and the spacer sleeve 32 , which holds the cross member 14 between them.

Since the load-bearing capacity of plastic parts is limited, in any case lower than that of corresponding steel parts, the compressive force that can be applied between screw head 30 and spacer sleeve 32 and thus the frictional force against displacement in the direction of the longitudinal extension of the openings 28 cannot be made arbitrarily high. In order nevertheless to ensure that this axial displacement does not take place, a washer 34 is provided between the bolt head 30 and the end face of the sleeve, which is shown in FIGS. 3 and 4 as a washer 134 in a special embodiment. In both cases, both in the case of the disk 34 and in the case of the disk 134, the arrangement acts as a form-fitting device.

As shown, the washer 34 , 134 is made from a flat, round metal washer with a central bore 36 which is adapted to the shaft diameter of the threaded bolt 24 , while the outer diameter 38 is at least as large as the outer diameter of the spacer sleeve 32 or 132 . The disk 34 , 13 'has two opposite edge regions, and one edge region has an axially extending nose 40 , while the radially opposite edge region has a radially extending nose or extension 42 with an opening 43 . With the attachment 42 and the associated opening 43 , the disk 34 can be plugged onto a hook-shaped attachment 45 extending from the end face of the sleeve 32 , which enables the disk 34 to be secured with respect to the sleeve 32 while the nose 40 of the disk 34 in For example, an opening 44 made in the cross member 14 can be inserted near the keyhole-like opening 28 or 128 , whereby the disk 34 is secured against radial displacement in this position and thereby the desired form fit between cross member 14 , disk 34 , bolt 24 and oscillating system 12 is reached.

For reasons of injection molding, the sleeve 32 or 132 is not designed as a simple cylinder, but rather - to save material - specially designed, as is also shown in the prior art. For example, according to FIG. 6 (and the associated sectional view BB of FIG. 8), the upper end of the sleeve 132 is provided with a projection 46 which extends partially beyond the circular outer circumference 41 of the sleeve 132 and which comprises a recess 49 which is enclosed on all sides and into which the Nose 40 of the disc 34 , 134 can be added.

The disk 134 , which is particularly clearly shown in FIG. 4, can be placed or plugged onto the end face 50 of the sleeve 132 in the position shown in FIG. 4, a pin 29 projecting from the end face 50 fitting through the bore 36 in the disk 34 , The pin 29 could serve to receive and hold a spiral spring 27 or also another fixed or plastically deformable spacer sleeve which is supported on the one hand on the disk 134 and on the other hand is held on a washer 23 which in turn is held by the head 30 of the threaded bolt 24 is, which extends through the pin 29 of the spacer sleeve 132 and is screwed into a bore arranged within the vibrating system 12 so far that the disc 134 rests on the end face 50 and thus also the opposite end face 51 on the vibrating system 12 without play. In this position, for example, the traverse 14 of the household machine is held in the slot or circumferential groove 94 ( FIG. 5) formed below the end face 50 of the spacer sleeve 32 , 132 , the lug 140 formed by the disk 134 as a result of reaching through the opening 44 ( Fig. 2) of the rear wall or cross member 14 (penetrating into the depression 40 formed by the spacer sleeve 132 ) secured the arrangement against lateral slipping.

The two opposing bottom walls 91 , 92 , which delimit the slot 94 ( FIGS. 5, 6), are parallel to one another and have a distance which is slightly smaller than the width of the narrower section 76 of the keyhole opening 28 ( FIG. 2) , Characterized the spacer sleeve 132 is aligned so that the nose 40 of the disc 134 , which in turn is aligned by the neck 45 ( Fig. 4) and the pin 29 , comes to lie exactly above the opening 44 in the cross member 14 , if during the Assembly process, the spacer sleeve 132 is pushed in the narrow area 76 of the opening 28 in the direction of the associated opening 44 .

So that the nose 40 does not interfere with this displacement process, it is advantageous if it is first held above the plane of the cross member 14 and only comes into the position shown in FIG. 3 when the bolt 30 is tightened. In the prior art (DE 195 25 316 A1) lugs 82 are provided for this purpose, which press resiliently against the underside of the disk 134 and bring it into a raised position. In the embodiment shown in FIGS. 3 and 4 of the present application, a leaf spring 82 is provided instead, which presses against a further, hook-shaped projection 84 formed by the disk 40 , the leaf spring 82 being injection-molded in one piece from plastic with the spacer sleeve 132 .

To further facilitate assembly, it is used if a so-called thin-shaft screw bolt is used as the screw bolt 24 , in which the threaded region 86 has a larger diameter than the subsequent smooth shaft region 88 reaching up to the head 30 . Then if the sleeve 132 near its end lying on the form-fitting metal plate 134 has a transverse opening 90 ( FIG. 7) into which a locking slide 96 can be inserted, in such a way that it has the cross section 97 of the sleeve opening through which the Bolt 24 extends through so far that it can move axially with its thinner shaft area 88 , but the threaded area 86 no longer passes through this narrowed cross-section 99 , which the locking slide 96 forms, but strikes against it. The locking device consisting of the various components therefore does not fall apart unintentionally if the fixing device as described here is removed when the washing machine or the like is started up. In particular, there is no risk that when the screw 30 is loosened from the oscillating system 12 and pushed out or pulled out, the overall arrangement of the openings in the cross member 14 or rear wall 20 of the washing machine will separate the component 132 from the other parts and into the interior the washing machine falls. If, on the other hand, the slider 96 is in the pulled-out position shown in FIG. 7, the cross section 97 is completely free and the screw 24 can be inserted freely with its threaded region 86 as well as with its shaft region 88 through the bore in the sleeve. If the fitter then forgets to pre-assemble the arrangement, push the slider 96 in so far that the locking occurs by the U-shaped area 99 formed by the slider 96 laying around the thin shaft area 88 of the screw 24 , this is visible because the Slider 96 clearly emerges over the outer circumference of the sleeve 132 . The fitter is therefore reminded to insert the slider 96 , preferably to such an extent that, with projecting lugs 101 , it lies down in a locking manner in the recess areas 102 formed by the opening 90 . The still protruding slide 96 would also hinder the introduction of the spacer sleeve 132 into the larger area 28 of the keyhole-like opening in the crossmember 14 , so that even if the screw bolt was actually forgotten to be locked, the installer is reminded of his failure and this process is made up for.

The opening 90 and thus the slider 96 preferably have a rectangular cross section, the slider 96 having a U shape in plan view, see FIG. 7, so that it engages the bolt shaft 88 with the inner surfaces 103 of the legs of the U shape The position of the slide can be gripped in such a way that the thread 86 having a larger diameter is prevented from passing.

It has already been pointed out that the locking slide 96 has a projection 101 (it can also be a recess) on the outer surfaces 105 of the legs, which protrudes into a recess 102 (alternatively a projection) which is located in the two side walls lying parallel to the pin axis 107 is located, can engage, in such a way that the locking slide 103 has reached the position in which the bolt shank 88 is embraced by the cross-section 99 of the slider.

The two sectional representations of FIGS. 7 and 8 further show that the sleeve 132 is not solid, but rather has a shape essentially formed from different wall areas, which saves material and at the same time results in high strength. This corresponds to the prior art, in particular various longitudinal walls 64 , 66 , 68 , 70 ( FIG. 8) can be seen, which are stiffened at both ends of the sleeve by closing transverse walls 71 , 72 ( FIG. 4).

So that in the released mounting position, the disk 34 can be raised, for example, by the leaf spring 82, so that the nose 40 lies outside the slot plane of the slot 94 , which includes a certain inclination because the disk 34 on the opposite side through the clip attachment 45 , which extends through the opening 43 and is held, the opening 36 and the opening 43 are provided with sufficient play with respect to the extension 29 and extension 45 . So that there is nevertheless a good alignment with respect to the lug 40 above the opening 49 receiving it, side walls 109 are provided on the end face 50 of the sleeve 132 in the area from which the leaf springs 82 originate, which align the corresponding area of the disk 34 in FIG Intervene. At the same time, these side walls 109 reinforce the stability of the leaf springs 82 .

The spring-like approaches 82 serve z. B. at the same time as a protective device for the surface of a connecting cable 111 , which is held by the U-shaped extension of the disc 134 in the assembled position. This has the advantage that the cable does not fly around in a disturbing manner during transport, on the other hand sharp edges of the hook 84, which is made of punching material, cannot press into the soft surface of the cable and damage it.

The assembly process takes place in such a way that in a device according to FIG. 1, at the four fastening points 228 which can be seen there, a device provided with a spacer sleeve 132 is inserted through corresponding bores 26 in the rear surface 20 of the device 10 and the thread of the screw bolt 24 partially in the associated hole of the vibrating system 12 is screwed or cut. The screwing takes place so far that the disc 134 inserted or inserted with its extension 140 into the incision 83 between the two leaf springs 82 , which is held in position by the hook-shaped extension 45 extending through the opening 43 , still above that of the Slot 94 formed level lies. Now the traverse 14 can be gripped and inserted with its two openings 28 over the screw heads 30 and the associated disk 34 (according to FIG. 2) or over the disk 23 and the spring 27 (according to FIG. 3) until the material thickness of the Cross member 14 sits between the slot walls 113 , 115 , whereupon the cross member 14 can be axially displaced in the corresponding gap 94 until the shaft of the screw bolt 24 reaches the narrowed area of the keyhole-like opening 28 , 128 , 228 , which is shown in FIG 76 is designated. As soon as the screw shaft reaches the end of this narrowed area 76 , the nose 40 of the washer 34 is located just above the opening 44 according to FIG. 2, for which purpose it only has to have a corresponding distance from the opening 28 . During this sliding process, the projection 45 prevents unwanted twisting, so that the nose 40 actually comes to rest over the opening 44 . These breakthrough openings 44 can be arranged on both sides of the breakthrough 28 , so that the direction of displacement can be selected as required. By moving the cross member 14 , both of the fastening screws 24 provided here can be brought into the correct arrangement at the same time, so that subsequently both screws can also be tightened, during which tightening the nose presses against the force of the leaf spring 82 , which presses against the hooks 84 , passes through the opening 44 into the depression or the hole 49 , whereby the overall arrangement is secured against displacement.

The contact surfaces 18 of the crossmember 14 are pressed against the edge areas of the rear wall 20 of the household appliance 10 by screwing on and expediently held in a locking manner by appropriate shaping (projections) without special fastening measures being necessary here.

Finally, the household machine is in place, the screws 24 are loosened and removed together with the cross member 14 from the rear wall, after which only the openings 26 and corresponding incised and provided threads in the container 12 remind of the transport lock.

According to another area of application can be temporarily attached Interior panels or support rails in motor vehicles by means of the arrangement according to the invention are fixed without the later removal of the Holding rail, paneling or the like. There is a risk that spacers z. B. on inaccessible parts of the body and remain while driving Bother rattling.
