Description

Technical area

The present invention relates to a door stop and a commercial vehicle, for example a vehicle trailer, which is equipped with at least one door stop of the type disclosed here.

background

Door stops are used in particular on commercial vehicles such as trucks or vehicle trailers whose commercial vehicle bodies have one or more doors. These doors must be prevented from accidentally slamming or moving when open.

The doors are often mounted so that they can rotate beyond 180°, so that, for example, rear doors abut close to the outside of the commercial vehicle body. This is necessary, for example, in order to be able to unload loads from a commercial vehicle trailer without any problems. Furthermore, it is also possible for loads to be transported using commercial vehicles of the type of interest here with the doors open, in particular, for example, excessively long loads that protrude from the rear area of a commercial vehicle when the doors are open. One or more doors of the commercial vehicle are swung out by over 180° or by 270° and fixed to the side of the outside of the commercial vehicle body by means of known door stops in order to prevent the doors from kicking back or unintentionally moving, among other things, while driving.

From the DE 20 2010 000 569 U1 A door stop is known, some of which have functional parts mounted next to each other outside the door. This door stop uses the so-called hooking principle or locking lever claw principle However, for reasons of space, it should be equipped with side-by-side and gripping functions as well as an area setting outside the door. There is the possibility of movable attachment to a vehicle column on a guide frame. The desired function time should be adjustable with an adjusting screw. It should be attached to the door using a security bolt.

This well-known door stop is complex and expensive due to the many moving parts.

The EP 2 664 735 A1 shows a door lock for commercial vehicle bodies, which is equipped with a fixed lever that can be adjusted between a non-use position and a use position, in particular for locking an open door of a commercial vehicle body. The locking lever is at least partially accommodated in a housing in the non-use position. In the use position, this locking lever blocks the door from closing. The locking lever itself is connected to the housing via a spring means. In the position of use, the locking lever is at least partially pulled out of the housing against the restoring force of the spring means. In order to ensure greater operational safety, the locking lever should comprise a shaft part with a cavity and the spring means should be at least partially accommodated in the cavity of the shaft part when the locking lever is not in use.

Here, too, there are many moving parts that are quite expensive to manufacture and assemble. There is also a risk that the side of the vehicle body or the side outer tarpaulins or the inside of the doors will be damaged by constant banging or rubbing against each other.

Another door arrester for commercial vehicle bodies is from the DE 20 2019 106 114 U1 known. This door stop includes a bar that is at least partially surrounded by a spring and which is rotatably mounted in a housing and movable along its longitudinal center line. A pivoting lever is oriented at a maximum angle of 90 degrees to the rod. There are two tabs on the housing, each with an opening for the rod to pass through. The spring is supported between the tab facing away from the lever on the side facing away from the lever and a stop provided on the end of the rod facing away from the lever. As with the previous designs of door stops, here again there are several mutually movable and spring-loaded and therefore complex parts.

The EP 3 238 968 A1 shows a door holder with which a door of a vehicle trailer can be fixed in the desired position and angle during a loading or unloading process. For this purpose, a U-shaped receiving element can be pivoted from a rest position into a use position via a rotating arm about an axis of rotation extending along the longitudinal axis of the vehicle. The U-shaped receiving element is provided with a locking bolt into which a tongue of a door lock can be hooked. This configuration is disadvantageous in that, under certain circumstances, sharp-edged parts of the U-shaped receiving element can come into contact with vehicle parts and thereby damage them.

In the FR 2 764 627 A A door stop is disclosed which can be moved from a rest position to a use position. For this purpose, spring-loaded parts are again rotatably mounted in a housing etc. Because of this, as with the prior art mentioned above, expensive individual parts are required, which increases production costs.

Door stops are also known on the market in which a pivotally mounted arm can be hooked into a receptacle mounted on the door to be locked. True, there are fewer parts here and in particular none Springs are available, but here too a special part must be mounted on the door to be fastened or locked. This part can in turn become damaged. A pivotally mounted arm can be present on the vehicle to fix the door using a spring.

All known door stops have the particular problem that they consist of many parts, which are also usually movable in relation to each other. This makes such door stops expensive and complex to manufacture. In addition, such door stops are also relatively heavy.

The technical problem underlying the invention is to create a door stop in which one or more of the problems mentioned are at least reduced or even eliminated.

Summary of the invention

The problem on which the invention is based is solved by a door stop which is designed to lock a door of a commercial vehicle, in particular a truck trailer, in the open state. Such a door stop comprises a holding arm which can be movably attached to a component of the commercial vehicle at at least one bearing point. Furthermore, there is a contact element rigidly connected to the holding arm. The contact element is designed as a contact plate and is provided with at least one engagement opening into which a tongue of a pivotable locking device present on the door can be inserted into a position of use of the door stop for fixing the door to be locked in the at least one engagement opening of the contact plate. By moving the door holder from a rest position to the use position, the contact plate can be positioned essentially parallel to the door to be locked. In this position, the contact plate for the door to be locked serves as a contact surface and fixation point at a defined distance from a commercial vehicle part and the tongue of the pivotable one on the door Locking device in the use position of the door stop for fixing the door to be locked can be brought into the at least one engagement opening of the contact plate.

The (temporary) fixation of the door on the contact surface in the position of use by the tongue of the pivoting locking device on the door, as shown, for example EP 3 276 112 A1 is known. The tongue can be inserted into the engagement opening and - as in normal use - the locking device can be locked with the tongue on the contact element. The contact element and the holding arm can also be detachably connected to one another.

In a further exemplary embodiment of the present invention, the contact element preferably forms an angle with the movable holding arm of less than 100°, in particular between 80° and 95°, preferably an angle of essentially 90°.

In a further exemplary embodiment of the present invention, the holding arm is curved and can be slidably guided at at least one bearing point on a component of the commercial vehicle, so that the door stop can be brought from the rest position into the use position by moving relative to the bearing point, in which the contact element is essentially is positioned parallel to the door to be locked. Again, a tongue of a pivotable locking device on the door can preferably be inserted into the engagement opening.

In this embodiment, the arcuate profile can be transferred from a rest position to a use position with a contact element. A locking can take place, for example, via a notch or groove that "hooks" into a rib on the vehicle structure, for example by its own weight, or via a spring latch or the like. In a further exemplary embodiment of the present invention, the holding arm is designed to be rectilinear and can be slidably guided at at least one bearing point on a component of the commercial vehicle, so that the door stop can be brought from the rest position into the use position by pulling it out relative to the bearing point, in which the contact element is in Is positioned essentially parallel to the door to be locked. As with the other exemplary embodiments, a tongue of a pivotable locking device present on the door can preferably be inserted into the engagement opening. This door stop according to the invention can be used via a pull mechanism, among other things be mounted so that it can be extended in a horizontal arrangement, for example under the commercial vehicle body or within the frame structure. The contact element with the engagement openings can be present on an extendable profile or the counterholder for an existing door locking device can be mounted. The extendable profile can, for example, be locked via a spring latch or a spring-loaded bolt or fixed at a defined distance.

What all exemplary embodiments can have in common is that in the rest position the contact element does not protrude beyond the outside of the vehicle, i.e. in particular it is not positioned in front of the outside of the tarpaulin.

The invention is based on the idea of creating, for the first time, a movable counter-holder for a locking element, such as a locking tongue, which is already attached to the door to be locked. The door holder according to the invention simulates a holder for a locking device already present on the door using simple means and in a cost-effective manner. This makes it possible to lock an open door in a defined position - preferably without additional locking means - so that it cannot hit, rub or chafe against the side wall or tarpaulin of the commercial vehicle body or damage the inside of the door due to a spring-loaded locking lever, among other things due to coating technology (vibration, dynamic load during driving, friction, etc. Damage to the paint layer or zinc coating and subsequent corrosion). In particular, not when driving with the doors open, as may be necessary, for example, if the load is too long. In this way, the door is firmly fixed at a defined distance from the respective side of the vehicle and the side tarpaulin or side structure is not damaged by contact (“chafing”). The door lettering or side tarpaulin advertising is not scratched and the coating on the inside of the door is not damaged by a locking lever and rubber buffer rubbing on the inside of the door.

When driving with the doors closed, the door stop according to the invention can be folded away in a preferred embodiment, so that none of its parts protrude beyond the outer edge of the commercial vehicle body and can be damaged, for example, when maneuvering the commercial vehicle. For locking both in the use position and in the rest position, for example, a spring-loaded pusher element, as is well known, is attached to the pivot arm of the door stop, so that This spring-loaded pusher element can engage in appropriately shaped holes, openings or recesses in the commercial vehicle frame in the respective position and is secured in this position. By overcoming the spring force, it is possible to move out into the respective position, i.e. from the rest position to the use position and vice versa or via spring force/tension spring.

Alternatively, it is also possible to attach a device that generates tensile force, for example a tension spring or a rubber band, with one end to the holding or swivel arm and with the other end to the commercial vehicle frame in relation to the pivot or pivot point of the swivel arm that the door stop is pulled into the rest position and, after overcoming the dead center around the bearing point of the door stop, is held securely in the position of use.

The door arrester according to the invention can easily be retrofitted to existing commercial vehicles regardless of the existing door lock, in particular also to commercial vehicles with a locking device, as shown in the EP 3 276 112 A1 are described.

Due to the simple design, significant weight savings can be achieved. In addition, the purely mechanical solution is almost maintenance-free. In a preferred embodiment with a swivel arm, a weight saving can be around 400 grams per component compared to a spring-loaded locking lever.

The complex spring-pull mechanism previously used can be omitted and wear-prone rubber buffers or PVC covers on the door stop are no longer necessary.

By firmly fixing the door to the contact element, among other things, at a defined distance (including without contact between the outside of the door and the side tarpaulin), damage to the side tarpaulins, among other things, is excluded while driving with the rear doors open. The defined distance can be adjusted according to the technical design of the new door stop can be varied taking into account the vehicle structure (front wall, side tarpaulin, sliding walls, etc.). Rear door external labels or side tarpaulin labels or side structure labels or frame external profiles are no longer damaged by contact or friction of the rear door outer surface with the outer side tarpaulin surface, as is the case in the prior art. The same applies to the coating on the inside of the door.

For the same reason, there is no damage to the inside of the door, which is often made of zinc sheet and has a coating as a result of the inside of the door not being touched or fixed. This prevents corrosion.

In addition, a further door handle on the rear door side can also be fixed “behind” a door stop according to the invention by positioning it behind the contact element. The second, outer door handle is locked by the lock itself. Neither the first nor a second door handle on a door can move unintentionally after being fixed and, for example, protrude to the side of the commercial vehicle while driving.

A door stop according to the invention can be installed on any commercial vehicle by movably attaching it to the vehicle in the desired position, for example by means of a screw bolt, which creates a pivot bearing at the bearing point (pivot point).

In an exemplary embodiment of a door stop according to the invention, the contact element comprises a contact plate which, with the swivel arm, forms an angle of less than 100°, in particular between 80° and 95°, preferably an angle of essentially 90°. This makes it possible to provide a secure counter bearing for abutting the door in a structurally simple manner and to lock the door on the door stop by engaging in the engagement opening.

In order to ensure that in the position of use of the door stop according to the present invention in a clearly defined Distance from the outer wall of the commercial vehicle body is locked so that the door locked on the door stop cannot strike against the outside of the commercial vehicle body, the inside of the contact element, which faces the bearing point, has such a distance from the bearing point that in the position of use the contact element is at a distance is positioned to the outside of the commercial vehicle body and there is a (fixed) air gap of at least 5 mm, in particular 1 - 10 cm, to the outside of the commercial vehicle body.

Preferably, a releasable locking device that can be operated by an operator is present in order to fix the door lock in the position of use.

A further exemplary embodiment of a door stop according to the invention provides that the pivot arm and the contact element are formed in one piece. This one-piece design enables rigid, safe and very cost-effective production. Such a door stop can be made as an injection molded part, for example made of cast iron or plastic or cast steel or cast aluminum. Alternatively, it is also possible to design a pre-cut sheet metal part by forming, in particular edges, with a swivel arm and contact element. By using a pre-cut sheet metal part, which has been pre-cut, for example using lasers, and which already includes all the necessary openings and weight-reduction recesses, a door stop according to the invention can be created in a cost-effective, simple and very stable manner.

The rigidity of such a door stop is increased in particular by the swivel arm and/or the contact element comprising one or more stiffening edges, that is to say having bends of 45°, or in particular 90° or more, at outer ends, which increase the rigidity of a plate-shaped component.

The rigidity of such a door stop is further increased by welding the joints of adjacent components such as stiffening edges and butt lines of the swivel arm and/or contact element to one another.

However, such welds are not absolutely necessary because the folds increase the rigidity. A sheet metal part with a thickness of 0.5 - 10 mm, preferably 3-6 mm, more preferably approx. 4-5 mm is preferably used. The sheet metal part can be made of steel/structural steel S355, for example. A production from z. B. aluminum, POM (polyoxymethylene) is also conceivable.

A further exemplary embodiment of a door stop according to the invention comprises a contact element which has a first engagement opening and a second engagement opening spaced therefrom. The first engagement opening is designed in such a way that the locking tongue of the locking device on the door, coming from the outside of the contact element, can be retracted into the first engagement opening and can reach behind it. The second engagement opening is positioned on the contact element in such a way and designed in such a way that a locking pawl of the locking device on the door can be retracted into this second engagement opening from the outside and can reach behind it (releasable fixation).

This design of the door stop according to the invention enables an extremely secure locking of the door on the contact element of the door stop according to the invention. Particularly when driving, accidental release of the door lock and thus the door from the door catch is avoided or absolutely prevented.

A further exemplary embodiment of a door stop according to the invention provides that the contact element has such a length transverse to the pivot arm that a further handle lever, which is arranged on the commercial vehicle body, and thus on the door to be locked, can also be clamped behind the contact element. On the one hand, this also makes it possible to further secure the door on the contact element and, on the other hand, this provides security with regard to the swinging out of the further handle lever. This prevents the handle lever and the door from swinging out unintentionally and thus prevents a potential risk of injury or damage, for example when maneuvering in depots with the door open.

If there are two locking devices for a door, the contact element or the attachment element can be provided with locking counterparts that are complementary to both locking devices, for example with four engagement openings or four locking rods. Alternatively, the second handle lever is clamped behind the contact element.

Another aspect of the present invention relates to a commercial vehicle with a door stop according to the invention. Of course, it is also possible to attach several such door stops to suitable locations on the commercial vehicle. A commercial vehicle according to the invention thus comprises a rotatably mounted door and a locking device for the door in the open state. The door locking device in turn comprises a handle element which is movably attached to the door and has a locking section having a tongue for locking the door (or counter-holder when using an "original door handle"). Furthermore, a vehicle frame is present with a frame element in which a holding section is formed. In addition, a tongue opening is formed in the frame element, in which the tongue of the door locking device can be received. In particular, commercial vehicles and in particular door locking devices are suitable for this, as described in the EP 3 276 112 A1 are revealed. Door stops according to the invention then have the corresponding engagement openings to accommodate the one or more described herein To accommodate locking tongues and pawls in the contact element of the door stop according to the invention. Innovative door stop can be used to lock or fix rear doors, side doors, front doors, folding side walls, etc.

The holding arm and the contact element are preferably formed in one piece.

In a further exemplary embodiment of the present invention, the handle element has a locking pawl and the holding section has, in addition to the tongue opening, a pawl opening formed in the frame element for receiving a locking pawl.

In a further exemplary embodiment of the present invention, the mounting section is integrally formed in the frame element of the vehicle frame.

In a further exemplary embodiment of the present invention, the handle element has an elongated main body with a longitudinal axis and the tongue extends substantially along the longitudinal axis and has a substantially arcuate shape in a first plane parallel to the longitudinal axis.

Detailed description

The perspective rear view of a commercial vehicle 5 according to the Fig. 1 comprises a commercial vehicle body 15 with two pivoting rear doors 20, 21.

The rear doors 20, 21 are each pivotally mounted on the outside with door hinges 25. The door hinges 25 enable the doors 20, 21 to be pivoted by more than 180° and up to 270°, so that the doors 20, 21 can be positioned parallel to the outside 26 of the commercial vehicle body. In particular, the hinges 25 are designed as so-called double-jointed hinges.

The commercial vehicle body comprises a vehicle frame with a frame part 10 in which there are holes which in turn serve as engagement openings for the various locking devices 30 - 33. These locking devices 30 - 33 each include a locking tongue and a locking pawl. Details on this can be found in those already mentioned EP 3 276 112 A1 be removed. In the view shown according to the Fig. 1 A door stop 50 according to the invention is shown on the left in the position of use.

In the Fig. 2 the door stop 50 is also arranged in the position of use, that is, the door stop 50 extends essentially parallel to the outside 26 of the commercial vehicle body 15. Here the locking device 32 is designed with a handle lever 40, on which a locking tongue 41 is present. This locking tongue 41 engages in an engagement opening 60 of the door holder 50, which will be discussed later, and thus holds the door 21 in a fixed position, parallel and without contact at a defined distance with an air gap to the outside 26 of the commercial vehicle body 15. In the Fig.2 the door 21 is shown with its inner door frame 22 pointing in the direction of travel, that is, the door 21 is arranged in its fully swiveled position.

The Fig.3 shows further details of the door stop 50. Here the door stop 50 is shown in an intermediate position between the rest position and the use position. The door stop 50 is rotatably attached to a cross member 11 of the vehicle frame 10 at the storage point 53. The cross member 11 has recesses or holes 110, 115 into which a locking element can be snapped.

The hole 110 is used to lock the door stop 50 in the position of use. The hole 115 is used to lock the door stop 50 in the rest position. For latching, the door stop 50 has a spring-loaded pusher element 54, which is arranged at the tip of the pivot arm 52 so that the spring-loaded pusher element points towards the cross member 11. Further information on this can be found using the Fig. 4 .

In the Fig. 4 A cross section of an exemplary spring-loaded pusher element 54 is shown. The spring-loaded pusher element 54 comprises a housing 54a with a spring 54b mounted therein, which presses a locking ball 54c against a housing stop. The locking ball 54c fits into the holes 110, 115.

When an operator unscrews the door stop 50 from the rest position in which the ball 54c protrudes into the hole 115, the ball 54c is displaced into the housing against the spring force of the spring 54b, whereby the door stop 50 can be pivoted outwards until the Locking ball 54c engages in hole 110. In this position of use, a contact plate 51 is located approximately parallel to the outside 26 of the commercial vehicle body 15. The contact plate 51 has at least one opening 61 into which the tongue 41 of the locking device 32 can be retracted and can reach behind it. As a result, the door is firmly locked on the door stop by resting on the contact plate 51. Even while the commercial vehicle is driving, the door cannot strike against the outside 26 of the commercial vehicle body 15 and possibly damage it.

In the Fig. 3 and especially the others Fig. 5 It can be seen that a door stop 50 according to the invention includes the swivel arm 52, which in turn is designed with an opening 53 as a storage point for a swivel joint opposite the cross member 11. The storage point can then be used as a swivel joint for a screw bolt, for example. The swivel arm 52 is formed here by edging a sheet metal part. Further bends can increase the bending rigidity of the contact plate 51 and the connecting plate 55.

For reinforcement, further bends 56, 57 are made and, if increased rigidity is desired, welds can be made on the butt lines 58, 59, 60, i.e. fillet welds can be set.

Like especially in the Fig. 5 shown, there are two engagement openings 61, 62 here, one opening 61 of which serves for the locking tongue of the door locking device. The opening 62 serves to engage and reach behind the locking pawl of the locking device, if such a pawl is present.

A further exemplary embodiment of a door stop 50′ according to the invention is shown in FIG Fig. 6 shown. The structure of this door stop 50' is essentially identical to that of the preceding drawings, but there is a tension spring 105 here, which is attached to the underside of the commercial vehicle body via an eye 100. The other end is attached to the connecting plate 55.

The bearing point 53, i.e. the swivel joint for the door stop 50 ', is selected so that the door stop 50' is pulled into the rest position by the spring 105, as in Fig. 6 shown.

If the door stop 50 'is pivoted outwards by an operator around the bearing point 53, the spring force of the spring 105 causes the door stop 50' to be moved over the dead center position by the spring force of the spring 105 in Fig. 2 position shown. This eliminates the need for the spring-loaded pusher element 54 in this embodiment, as shown in FIG Fig. 2 - 4 is shown.

In the Fig. 7 an example of a door stop 50 not according to the invention is shown. Here an application element 200 is attached to the holding plate. This application element 200 is screwed to the holding plate using screws 202. Of course, it is also possible to attach the application element 200 in a detachable or fixed manner in another way, for example by welding.

The application element 200 serves here as a counterholder or locking counterpart for a respective locking device 30-33. For this purpose, locking rods 204, 206 are present, which serve as counterparts for the tongues 41 of the locking devices. Thus, the mounting plate itself does not have to have the engagement openings explained above, but the application element 200 can be designed in accordance with the locking devices present on the doors 20, 21, i.e. also be adapted to known designs of doors or their locking devices. In addition, the application element 200 can be subsequently adapted to any type of locking.

In the perspective view according to the Fig. 8 It can be seen how a first locking device with a handle lever 40 is locked on the application element of the holding plate or contact plate of the door stop 50. The second handle lever 40 of the further locking device on this door is clamped behind the end piece of the contact plate of the door stop 50. This prevents unwanted movement of this second locking device in a simple manner.

In the side view according to the Fig. 9 A further exemplary embodiment of a door stop 300 according to the invention is shown. Here the door stop 300 is designed with an arcuate holding arm 302 the front end of which the contact element 305 is rigidly welded or otherwise attached.

There are preferably two spaced-apart bearing arms 310, 312 on the commercial vehicle body, which are provided with openings, shown only schematically here, through which the arcuate holding arm 302 extends. The arcuate holding arm 302 is slidably guided in these openings. At the in the Fig. 9 In the view shown, the door stop 300 is shown in the rest position, i.e. pushed laterally into the commercial vehicle body. The bearing arms 310, 312 can also be formed by the frame structure itself.

The Fig. 10 shows the door stop 300 according to the invention according to the Fig. 9 in the position of use. Here, the arcuate holding arm 302 is moved outwards - guided in the openings of the bearing arms 310, 312 - until a groove 308 on the underside of the arcuate holding arm 302 snaps into a suitable rib of the bearing arm 310, for example through its own weight force. In this position, the contact plate 305 attached to the front end of the holding arm 302 is aligned parallel to the structure and positioned at a defined distance from it.

It is of course also possible to attach a separate application element 200 to the holding plate. The locking devices of the door are then locked on the application element.

Another exemplary embodiment of a door stop 400 is in the Fig. 11 shown. Here, the door stop 400 is provided with an elongated, straight sliding arm 402, which is mounted in a corresponding guide on the commercial vehicle. At the front end there is again a contact plate 405 with engagement openings 408, 410, which serve to accommodate the locking devices on the door 20.

An operator can use the door stop 400 from a rest position below and within the outer limits of the commercial vehicle body pull it out into a position of use, in which locking is then possible using a tongue-and-groove connection or the like. For example, a simple push button, as described above, can also be provided as a locking mechanism. This means that the door resting on the holding or contact plate 405 in turn has a fixed counter bearing on which it can be locked, without any parts unintentionally rubbing or rubbing against the outside of the commercial vehicle body.

Commercial applicability

The door stops 50, 50', 300, 400 are moved by an operator from the rest position to the position of use and, depending on the design, are held in the position of use by snapping into place or leading over the dead center position or by moving and snapping into a groove or recess. A door can then be pivoted outwards and firmly locked on the contact plate or on the application element or counterholder on the contact plate of the respective door stop 50, 50', 300, 400 using the existing tongue and/or latch.
