Description

The invention relates to a holder system for fastening a container to a vehicle, in particular for fastening a compressed air container to a commercial vehicle.

From the publication EP 1 970 273 B1 (0) a fastening system of a cylindrical compressed air tank of a commercial vehicle is known, in which at least one profile rail extends on the outside of the pressure tank and is firmly connected to the pressure tank. In the profile rail, a connecting element that can be firmly anchored to the vehicle is guided so as to be slidable in the longitudinal direction of the profile.

The publication AT 11076 U1 (1) describes a connection system for vehicle containers, in particular cylindrical compressed air containers. These compressed air tanks are also equipped with at least one profile rail, on or in which a connecting element for connecting two adjacent tanks is slidably arranged. (over a large displacement path)

The EP 2 048 427 B1 (2) relates to a compressed air reservoir in the form of a cylindrical body which has fastening devices which are integrated into the housing of the compressed air reservoir and are used for fastening the cylindrical body to the vehicle or for fastening a plurality of compressed air reservoirs to one another. These fastening devices have a grooved section, the groove being T-shaped or dovetail-shaped.

DE 299 12 337 (3) already discloses a rail system for fastening a container.

The decisive disadvantage of these aforementioned solutions is that the pressure vessels with the profile rail for assembly or disassembly with the connecting element have to be moved over a relatively long joining path or displacement path and that it is difficult to thread the connecting element into the profile rail during assembly.

In the DE 20200501875U1 an L-shaped bracket is provided on the bottom of the container for attachment to the vehicle.

In the DE 298 22 006 U1 a hood-like sheet metal part is used, which is attached to the pressure vessel at its 4 side edges. The lateral threading of a connecting element is not possible here.

The object of the invention is to provide a simple fastening of a container to a vehicle with a short assembly path.

This object is achieved with the characterizing features of the first claim.

• - das Halterungselement mindestens einen am Behälter befestigten ersten Bereich aufweist, der sich vom Behälter weg erstreckt,

1 shows a jacket section of a rotationally symmetrical pressure vessel 1 (preferably a compressed air tank) with an attached U-shaped mounting element 2nd and a loss protection 3rd . The bracket element 2nd has a slot 4th with an area open on one side 5 on. When attaching more than one bracket 2nd point the open areas 5 of the individual mounting elements 2nd in the same direction. The slots 4th extend here in their unidentified longitudinal direction essentially in the direction of the longitudinal axis A of the pressure vessel jacket 1 . In every slot 4th was over the open area 5 an indicated connection means 6 inserted, which is the mounting element 2nd through the slot 4th engages behind. The suggested lanyard 6 serves to define the pressure vessel 1 for example on a carrier of a commercial vehicle, not shown.
The lanyard 6 consists of a fastener 7 which is the mounting element 2nd reaches behind and a fastener 8th with which the fastener 7 and above the bracket 2nd and the container 1 be attached to the vehicle, preferably via a screw connection.

The lanyard 6 is pre-assembled on the vehicle, then the pressure vessel with the mounting elements 2nd on the lanyards 6 mounted. Then the fasteners 8th with the fasteners 7 further screwed and each mounting element 2nd attracted to a mounting surface, not shown, of the carrier or another area of the vehicle. Then the loss protection 3rd mounted, which extends through the carrier, not shown.

In the event that the fastener 7 and the fastener 8th of the lanyard 6 loosen, it prevents the holder 2nd from the lanyard 6 slips and the pressure vessel unintentionally detaches from the vehicle.

In 2nd the three-dimensional detailed view of an advantageous embodiment of the two here on the pressure vessel 1 attached bracket elements 2nd shown.
Any mounting bracket 2nd is with a first area 2.1 on the pressure vessel 1 attached, preferably welded, the first region then pointing away from the pressure vessel. From the first area 2.1 a second area extends essentially at an angle of 90 ° 2.2 in which the slot 4th is introduced. This is followed by a third area angled towards the container at an angle of approximately 90 ° 2.3 on, which also - preferably by welding - firmly with the pressure vessel 1 connected is. The lanyard 6 reaches behind with its fastener 7 the mounting element 2nd through the slot 4th towards the pressure vessel 1 and is using its fastener 8th for example on a side member 10th attached to a vehicle.
The bracket element 2nd when tightening the fastener 8th against the mounting surface 10.1 of the carrier 10th dressed. The fastener 7 is here in the form of a sliding block 7.1 trained who in the slot 4th one engages and when tightening the fastener 8th on the side edges of the slot 4th supports and thereby forms a torque arm. This means that the connection can be tightened with just one hand, since the sliding block does not turn.

One on the pressure vessel 1 attached bracket 2nd according to 1 and 2nd with in the slot 4th inserted sliding block 7.1 (= Fastener 7 ) is in 3rd shown.
The sliding block 7.1 engages with an engagement area 7.2 in the slot 4th of the mounting element 2nd and supports itself with two geometric elements 7.3 , 7.4 on the side walls (not labeled) of the slot 4th from. The mounting element is on its towards the pressure vessel 1 facing bottom of the second area 2.2 attacked by the sliding block. Will the fastener 8th - here in the form of a screw 8th - In the unspecified threaded hole of the sliding block 7.1 screwed in, the holder 2nd with his area 2.2 against the mounting surface 10.1 of the carrier 10th pressed. The fastener penetrates one in the carrier 10th intended bore not designated. Between the top of the carrier and the bottom of the head of the fastener 8th can be a first washer 11 be arranged. Instead of the washer 11 can also be arranged a spring ring or another suitable element.

4th shows one on the carrier 10th a pressure vessel attached to a vehicle 1 in the area of a mounting element 2nd with a fastener 7 in the form of a mother 7.5 and a fastener 8th in the form of a screw with a first washer 11 .
Between the mother 7.5 and the mounting element 2nd is a second washer 12th arranged. Instead of the washer 11 and or 12th can also be arranged a spring ring or another suitable element.
The mother 7.5 does not reach into the slot 4th on. Through the slot 4th only the unspecified screw shaft of the fastener leads 8th . This allows the width of the slot 4th be chosen smaller.
The disadvantage here is that when tightening the screw in the form of the fastener 8th on the mother 7.5 must be held against and so a one-handed fastening is not possible.

An insurance against loss 3rd by the carrier 10th is enough and the holder 2nd is supported on an edge, causing the connecting means to slip out 6 from the holder 2nd is prevented 5 .
The captive device can also engage in a bore, not shown, in the mounting element, which produces the same positive movement restriction. Here, the bracket element 2nd but weakened by the hole in its structure and must therefore be dimensioned differently.

The individual representation of a fastener 7 in the form of a sliding block 7.1 with a threaded hole 7G shows 6 . This has an engagement area which can be engaged in the slot 7.2 that acts as a torque arm. The area of intervention 7.2 has two parallel surfaces in the form of side edges 7.3 , 7.4 on. Between the two surfaces 7.3 , 7.4 is a first insertion area that reduces in width in the insertion direction 7R provided, which is designed here in the form of a radius.
This allows the sliding block to slide into the slot 4th of the holder 2nd also align yourself to a certain extent.

With the bottom 7F the sliding block engages behind 7 the mounting element 2nd (please refer 8th ) and with this when tightening the lanyard not shown here 8th against the mounting element 2nd pressed, whereby this is against the mounting surface 10.1 of the carrier 10th tense (see 3rd ).
7 shows the individual representation of a mounting element 2nd in an advantageous embodiment in plan view and 8th the same bracket element 2nd in the rear view.
In an advantageous embodiment, it is bent essentially in a U-shape and consists of a sheet metal part. It has a first area 2.1 on, which is welded to the pressure vessel, not shown here, and extends away from the pressure vessel. This is followed by a second area bent at an angle of 90 ° 2.2 a third area on and in turn at an angle of 90 ° towards the container 2.3 that is essentially parallel to the first area 2.1 runs. It can be seen that the geometric design of the mounting element can also implement designs other than the U-shape and other than the specified 90 ° angles and still perform the function described.
In the second area 2.2 is from the direction of the side edge 2.5 advantageously in the middle of the slot 4th brought in at its end here with a radius 4R is provided and has two mutually parallel longitudinal edges 4.1 , 4.2 on. The width of the slot between the longitudinal edges is the distance between the side edges 7.3 , 7.4 adjusted of the sliding block. The same function of a torque arm for tightening the fastener 8th can be achieved if the long edges 4.1 and 4.2 stand at an angle of up to 45 ° to each other and the corresponding edges 7.3 and 7.4 of the sliding block 7 are matched to it.
The radius 4R is the first insertion area here 7R adjusted of the sliding block. However, this is not a prerequisite for the function and the radius 4R can also be through a flat back wall 4F which are replaced in 7 is shown as a dashed line. Between the edges 4F and 4.1 respectively. 4.2 there may be a rounding radius.
Towards the side edge 2.5 the slot widens 4th to a second insertion area 4.3 . This can be carried out, among other things, in the form of one or more chamfers, one or more radii, a curve with a variable radius (for example a drag curve, an ellipse or a parabola) or a combination of these.
The second insertion area is in an advantageous embodiment 4.3 at the slot 4th a combination of 2 successive chamfers with the open side 5 increasing angle and rounding at the transitions between the chamfers, the side edges 4.1 respectively. 4.2 and the side edge 2.5 of the holder 2nd .

An advantageous embodiment with run-in chamfers and roundings of the second insertion area 4.3 is in 9 shown. Here are the lengths L1 , L2 , L3 between the side edge 2.5 of the mounting element 2nd and the radius R together with the opening angles W1 and W2 the determining dimensions of the second insertion area 4.3 .
The length L1 is therefore the distance between the side edge 2.5 and the end of the first chamfer of the second insertion area 4.3 .
The length L2 denotes the end of the second inlet area 4.3 and the transition to the side edges 4.2 respectively. 4.1 of the slot 4th .
The length L3 denotes the effective length of the slot, i.e. the distance between the side edge 3.5 and the end position of the axis of rotation of the connecting means 6 (not shown) after assembly.
The width B of the slot 4th is the width of the first insertion area 7.2 the fastener 7 or the shaft diameter of the fastener 6 customized.
The radius R denotes the rounding of the individual sections within the second inlet area 4.3 and at the transitions between this inlet area and the side edges 4.1 and 4.2 as well as to the side edge 2.5 .
The radius R not necessarily be the same size at all transitions.

Further advantageous configurations of the second insertion area 4.3 are in 10th in the form of a drag curve and 11 shown as inlet radius R.

It should be noted here that the precise geometric design of the second insertion area 4.3 to ensure the function of the self-centering of the fastener 7 cannot be described in all possible versions. Other designs of the second inlet area 4.3 are therefore quite possible and can lead to the functionality according to the invention.

The first insertion area 7.2 (please refer 7 ) and the second insertion area 4.3 ensure simple and safe "threading" (self-centering) of the fastening element 7 (not shown here) in the slot 4th of the holder.

This allows the connecting means to be pre-positioned roughly and thus quickly 6 on the carrier 10th on the vehicle with an angle of rotation of up to 100 ° in both directions compared to the final assembly state.
In 12th is the first insertion area 7.2 the fastener 7 in engagement with the second insertion area 4.3 of the mounting element 6 shown. The angle of rotation α of the fastening element 7 shown at 90 ° during assembly.

If a fastening means or fastening element does not engage the slot with a first insertion area, but rather with a shaft, then simple installation is also possible through the second insertion area 4.3 of the slot guaranteed. Here are the radius 4R , if present, and the distance between the long edges 4.1 , 4.2 adapted to the outer diameter of the shaft.

If a torque arm is to be used, it is also possible to use a fastening element 7 in the manner of a square nut 7.6 to use ( 13 ), which has a smaller square shoulder than the outer contour of the square nut 7.6` has, which can engage in the slot and is supported on it.

According to 14 can the fastener 7 in the form of a screw with a round head 7.7 and square engaging slot 7.7` , like or similar to a carriage screw. The fastener 8th then is a mother. The fastener in the form of a screw with a round head 7.7 and square 7.7` and the fastener 8th in the form of the nut then form the connecting means for fixing the pressure vessel to the vehicle via the mounting element fastened to the pressure vessel 2nd . The design of the screw head is important for the function 7.7 not mandatory as a round head. It can be seen that a cylinder head or any other suitable head shape also enable the use according to the invention.

At least two connecting means are preferred for each pressure vessel 6 intended.
If a holder with only one slot 4th provided, two holders can be attached to the container and these can be fixed to the vehicle with a connecting means.

However, only one holder can be used, the one with two or more slots 4th is provided. A connecting means then stands with at least two of these slots 6 for fastening to the vehicle in operative connection. Of course, more than two brackets attached to the pressure vessel can also be attached to the vehicle with one or more slots by means of appropriate connecting means.

It is also possible according to 15 a mounting element 2nd with two opposite slots 4th To be provided so that the pressure vessel (not shown here) from two different directions on the connecting means pre-assembled on the vehicle 6 can be hung. One or two bores can advantageously be used here 9 be provided to position the captive.

16 shows the principle representation of a on a vehicle profile or carrier 10th pressure vessel to be attached 1 (shown here in dashed lines) before inserting the two on the carrier 10th pre-assembled lanyard 6 into the two bracket elements 2nd on the pressure vessel 1 .
The pressure vessel 1 comes with the two bracket elements 2nd in addition to the lanyards 6 positioned and then with the brackets 2nd about the lanyards 6 pushed so that each connecting means engages in a slot of the holder. There is only a very small assembly path for this S required. The brackets are then held in position by the connecting element and can be tightened against the carrier via this ( 17th ).

18th shows the cut A - A according to 16 . It can be seen again that the connecting element 6 in the slot 4th of the mounting element 2nd engages and also on the back of the wearer 10th is applied and the mounting element 2nd on the mounting surface 10.1 of the carrier 10th abuts and is attached to this and thus also the pressure vessel 1 is fixed on the vehicle.

For the first time, the fastening element preferably includes a torque arm for assembly without holding back. Furthermore, it is due to its design and an inlet chamfer in the second insertion area 4.3 . ( 7 ) self-centering on the open groove during assembly (orientation of the fastening element during pre-assembly only roughly necessary) (+ -100 ° sufficient)

Alternatively, the fastening element can be rotationally symmetrical (without torque support). Then there may be no run-in chamfer in the second insertion area 4.3 of the slot 4th required. When mounting, however, a counterhold is then on Fastener 7 required to turn when tightening the lanyard 8th to prevent.
It goes without saying that the connecting means according to the invention 6 in the version without torque support in the fastening element 7 also by holding the fastener 8th and tighten fastener 7 can be assembled.

It is also advantageous to secure against loss by positive locking, for example in the form of an additional screw, which fits into a threaded hole in the mounting surface 10th the vehicle is screwed. The position must be chosen so that the edges of the slot in the case of a loose fastening element 4th not from behind the fastener 7 can slip.

This can simultaneously ensure that the fastener 6 its end position in the slot 4th of the holder 2nd has reached, otherwise the screw (captive) will not be on the edge 2.4 ( 5 ) over by the carrier 10th can be screwed.

Furthermore, the fastener 6 be secured against loss, for example by chemical screw locking (eg LOCTITE), a special screw with defined thread or diameter errors or also by a defined thread defect in the fastening element. Such fuses are already known from the prior art.
