Description

The invention relates to a closure device for a door of a caravan or motorhome according to the preamble of claim 1. Furthermore, the invention relates to a door, a storage or service room and a method for opening a door.

The invention can be used in particular in doors of caravans or campers, which usually have on the outer sides of several doors to close, for example, stowage and service rooms. In the storage rooms sometimes luggage or camping utensils can be stored and the service rooms can be used to hold gas bottles or water tanks.

Because of this diverse use of such spaces, in particular modern motor homes and caravans also have a whole series of doors of different sizes, which are distributed over the outside, so that the visual effect of caravans and motorhomes partly depends on the design of the doors.

For the purposes of this application, the term "door" is generally understood to mean a device for closing an opening, in particular on the outside, of a vehicle, ie also flaps, such as stowage flaps or service flaps, covers and the like. In particular, it is a hinged door.

In order to lock the doors against opening, it is known to provide closure devices on the respective doors to hold them in a closed position.

The closure devices usually have one or more locking elements and appropriately designed locking counterparts, in which the locking elements can engage. In a closed position, a movement of the two elements relative to each other is then prevented in such a way that the door can not be opened in this position. In order to open the door, the locking element must be disengaged from the locking counterpart and for a force directed against the closing direction to be applied.

In order to apply such a tensile force on the door, it is necessary that the door leaf of the door handle elements are arranged.

Usually even a handle element per locking element is provided, so that large doors often also has several handle elements. Also, due to the large number of doors, the overall visual impression of the caravan or motorhome therefore depends partly on these handle elements, which can sometimes have a negative effect on the aesthetics of the doors and thus also on the outer sides of the caravans and motorhomes.

Based on this, the invention provides the task to improve the overall appearance of a caravan or a motorhome.

This object is achieved in a closure device of the type mentioned by the features of claim 1 .

According to the invention, the locking element and the locking counterpart are designed such that they interact as push-push locking. By a push-push lock on the door handle elements are no longer needed. To open the door, it is sufficient to apply a compressive force, ie a "push" on the door leaf. This causes the door leaf initially moves further in the closing direction. However, when the force is removed, the door leaf can then spring back over the closed position so that the door leaf protrudes beyond the frame of the door. It can be applied over the edges of the door leaf, a pulling force and the door can be opened.

Preferably, the door has an opening support, for example in the form of a spring, which supports the opening of the door, so that the door opens automatically after the push unlocking.

Furthermore, the door can also be closed by a "push" on the door leaf, which is why neither opening nor closing the door handle elements on the door panel are needed, so that the visual impression of Exterior walls of the mobile home or caravan is improved. Furthermore, the aerodynamic properties of the motorhome or caravan are improved by corresponding handle-less doors, since the number of outwardly projecting and thus leading to turbulence parts is reduced.

To achieve the push-push locking, it is structurally advantageous if the locking counterpart has a guide for the locking element. The locking element can be guided in this guide and go through the guide in a closing or opening operation. The guide can be designed as a control curve, in particular as a heart train. To produce a corresponding guide this can be milled, for example, in the locking counterpart.

In terms of design, it has proved to be advantageous if the locking piece as flat as possible, for example, plate-shaped, is designed so that this requires very little space.

The locking counterpart may have fastening means, in particular recesses such as holes, via which it can be connected, for example, with screws or bolts to the door leaf or to the door frame. Such attachment is characterized by a low installation cost.

In particular, with regard to the guide, it has been found to be advantageous if the locking counterpart has a blocking region in which the locking element can occur during a movement in the shooting direction of the door. The blocking area can be configured such that the door is locked in this position, so it can not be opened by a pulling force. The blocking area may correspond to a corresponding one with the locking element Contour, so that the locking element can abut against this contour of the blocking area.

Furthermore, it has proved to be advantageous, in particular with regard to the guide, when the locking counterpart has a release area into which the locking element can fall out of the blocking area during a movement in the closing direction of the door. If the locking element is in the release area, the door can be opened.

With regard to the opening process, it has proved to be advantageous to the extent that the locking element automatically falls from the blocking area into the release area during a movement in the closing direction of the door. The blocking region may for this purpose have a run-on slope, on which the locking element can strike during a movement in the closing direction of the door and is then guided along this run-on slope from the blocking region into the release region.

Furthermore, it has proved to be advantageous if the locking counterpart has a closing area which is arranged between the release area and the blocking area and which is traversed during a movement of the door in the closing direction of the locking element. The closing region can be designed such that the locking element is transferred from the release region into the blocking region. Furthermore, the closing region may have a starting contour, against which the blocking element abuts when the door moves in the closing direction and is then transferred along the starting contour from the closing region into the blocking region.

Furthermore, it has proven to be advantageous if the locking counterpart has an opening portion which is between the blocking area and the release area is arranged and is traversed by a movement of the door in the opening direction of the locking element. In order to move the locking element from the blocking area into the opening area, this can first be moved by a movement in the closing direction of the door, with the result that the locking element abuts against the stop and is then transferred from the locking position into the opening area. The locking element can come through the opening area independently and then come to rest in the release area. The release area and the blocking area may be the areas in which the locking element rests when no force acts on it. It is advantageous if the locking element does not rest in the opening and closing areas, but only passes through these areas.

In terms of design, it has proven to be advantageous if the closing area has a run-on slope. About this run-in a malfunction of the closure device can be avoided. The run-on slope can be arranged in the release area facing the end of the closing area, so that the locking element must pass through the run-on slope during a transfer from the release area in the closing area. The opening area, which is likewise in direct contact with the release area, preferably has no run-on slope but an edge which can prevent the locking element from being moved from the release area into the opening area. In that regard, the starting slope ensures that the locking element always enters the closing area from the release position during a closing movement.

In view of the described movements, both the locking counterpart fixed and the locking element movable, as well as the locking counterpart movable and the locking element to be educated. Furthermore, it is also possible that both elements designed to be movable, provided that they are also movable relative to each other.

With regard to the locking element, it has proven to be advantageous if this is mounted in a receptacle. The recording can either on the door leaf of the door so that it moves with a movement of the door leaf, or be arranged on the door frame. The receptacle can be used for example in a door leaf recess or in a frame recess, so that it is flush with the door leaf or the door frame and only the locking element protrudes over the contour. The locking element may be designed rotationally symmetrical, for example as a mushroom pin or as a particular cylindrical pin. Furthermore, the receptacle and the locking element can cooperate as Verriegelungsbaueinheit.

With regard to the configuration of the receptacle, it has proven to be advantageous if it has a recess in which the locking element is guided. The recess can serve as a guide and be designed in terms of design, for example, as a slot or as a curved path.

Furthermore, it has been found to be advantageous if the locking element is resiliently mounted in the radial and / or axial direction. The locking element can move through this bearing both in the radial direction and in the axial direction relative to the receptacle.

With regard to this relative movement, it has proven to be advantageous if the locking element is mounted movably via at least one spring element, in particular a compression spring. The locking element can be moved against the force of the spring element. It is possible that only one spring is provided, but alternatively it is also conceivable that the locking element is mounted on a plurality, in particular two spring elements. Furthermore, manufacturing tolerances can be compensated via the resilient mounting.

With regard to the movement of the locking element, it has proven to be advantageous if this is movable in the direction of the recess, in particular linearly movable. By the spring element, which can act as a helical spring, for example, a linear force, the locking element along the recess can be linearly guided or be feasible along a curve.

With respect to the interaction of the locking element and the locking counterpart, it has been found to be advantageous if the locking element moves when passing through the guide in the recess. The locking element can be moved against the force of the spring when transferring from the release area into the closing area. The spring can ensure that the locking element automatically enters the opening area from the closing area during a push movement. The blocking region can be designed such that unwanted jumping out of the locking element is avoided.

In terms of design, it has proven to be advantageous if the locking element is spring-mounted to overcome the run-in slope in the axial direction. During a movement of the locking element through the closing region of the guide, the locking element can be tensioned against the force of a spring in the axial direction. Accordingly, this axial movement makes it possible for the locking element to enter from the release area only in the closing area and not in the opening area.

A further embodiment of the closure device provides that it has a locking device for locking the door against unwanted opening. The locking device can prevent opening of the door not only by a tensile force but also by a compressive force in the sense of push-push locking. This is particularly advantageous if, for example, an unintentional pressure force is exerted on the door leaf, which would then possibly lead to an unwanted opening of the door. For example, such unintentional pressure forces may arise during tunnel trips or in oncoming traffic, so that even in such situations accidental opening of the doors and falling out of the cargo can be prevented.

According to a structural embodiment of the locking device is proposed that this comprises a particular frame-side locking element which engages in a locking position in a particular door-side locking counterpart. The blocking element can be positively coupled in a blocking position with the locking counterpart, which can then prevent movement of the door leaf. It is also possible that the blocking element arranged door leaf side and the locking counterpart is arranged on the frame side. The blocking element can be actively moved, for example, by an actuator designed as a motor. Furthermore, it has been found to be advantageous if the locking device is arranged on the inside of the door, so that it is not visible from the outside. The movement of the locking element can be remotely operable and, for example, be coupled to the central locking of the motorhome or the caravan, so that a separate locking of all doors is eliminated. Further, it is possible that the locking device is coupled to an electrical system of the motorhome or caravan. By such a coupling can be achieved, for example, that the doors arranged on the outer sides automatically locked from a certain speed by the locking device so that the doors can not open unintentionally when driving.

The blocking element can be designed as a locking pin, in particular as a sliding bolt and the locking counterpart can accordingly be configured as a bolt receptacle. The locking device may be lockable. For example, it is possible that a lock is provided on the outside of the door leaf, via which the locking device can be converted into the blocking position or in the open position.

The object mentioned at the outset is also achieved by a door of a caravan or motorhome having a closure device , which is designed in the manner described above. This results in the effects and advantages already explained with regard to the closure device.

With regard to the design of the door, it has proven to be advantageous if the locking element and the locking counterpart is covered with the door closed by the door leaf. Due to this arrangement it is achieved that with the door closed none of these elements can be seen, which also enhances the overall visual impression of the vehicle.

Furthermore, it has proven to be advantageous in terms of the arrangement of the elements when the locking element or the locking counterpart is arranged in or on the door frame. Particularly preferably, the locking element or the locking counterpart is arranged on the door frame so that this does not protrude into the clear opening of the door frame and reduces it. This can be achieved, for example, by arranging the locking element and / or the locking counterpart in a frame rebate.

Furthermore, it is advantageous if the locking element and / or the locking counterpart are dimensioned such that they do not project beyond the fold of the frame and protrude into the clear opening of the frame.

With regard to the arrangement of the two elements, it is also advantageous if the locking element or the locking counterpart arranged on the door leaf, in particular arranged in a door rebate, so that the two elements can interlock with the door closed. The door rebate and the frame rebate can be configured in such a way that the door is flush in a closed position with the outer wall of the caravan or motorhome.

Furthermore, it has been found to be advantageous if the locking element or the locking counterpart is arranged on the front side of the door leaf.

It is also advantageous if the closure device is designed handleless. Such a handle-less design makes it possible that the door leaf is designed as a continuous in particular outwardly flat plate and the closure device is not visible from the outside. This allows a free design of the outer sides of the caravan or motorhome, since the optics impairing actuators, such as handles, are not needed. Furthermore, there are also advantages in terms of the aerodynamic properties of the caravan or motorhome, since comparatively much less protruding components must be arranged on the outside.

Furthermore, to solve the aforementioned problem, a stowage or service room of a caravan or motorhome with a door proposed, wherein the door is configured in the manner described above. This results in the effects and advantages already explained with regard to the door.

The object mentioned above is also achieved by a method for opening a door , in which the door is first moved in the closing direction and then only in the opening direction. It is advantageous if the door is designed in the manner described above. This results in the already explained effects and advantages.

Motorhomes and caravans often have on their outsides various doors 2, which are mostly used to close storage or service areas, as shown schematically in the Fig. 8 can be seen. In the storage spaces, for example, luggage, folding furniture or similar camping utensils may be arranged. Service rooms can be used, for example, for holding gas cylinders, waste water containers or the like. Therefore, a plurality of corresponding stowage and service spaces and therefore also a plurality of corresponding doors 2 are often arranged on the outsides of motorhomes and caravans.

Just as this also in the representation of Fig. 8 can be seen, the doors 2 can be designed very different in particular in terms of their size and the opening direction, which is why the doors 2 also contribute to a part of the appearance of the caravan or motorhome. As can also be seen, the corresponding doors 2 have on their outsides on no actuators to open or close, which offers both advantages in terms of the aerodynamic properties of the caravan or motorhome as well as with regard to the design of the Side walls.

In order to open the doors 2, a push-push lock is used, in which both for closing and for opening a door 2, a force in the closing direction S must be applied, so that no more handles are needed. In order to implement a corresponding push-push locking is on the frame of the door 2 in Fig. 1 represented lock counterpart 4 and arranged on the door leaf 2.1 of the door in Fig. 2 shown receptacle 7 and the locking element 3. The structural design of these elements that allow a push-push locking should, below based on the representations in the Fig. 1 and 2 to be discribed.

That in the Fig. 1 illustrated locking counterpart 4 has a guide 5, in which the locking element 3 is guided in a relative movement between the door leaf 2.1 and the door frame 2.2. This guide 5 consists essentially of four different areas 5.1 to 5.4, whose design and function will be explained below. According to the orientation of the Fig. 1 is in the upper part of the guide 5 of the release area 5.1 arranged. If the locking element 3 is located in this release area 5.1, the door leaf 2.1 can be moved relative to the door frame 2.1. In this position, the door leaf 2.1 stands out on the door frame 2.2, so that the door can be opened, for example, by a manual pulling movement or by the force of the opening of the door 2 supporting spring.

If a pressure force is applied to the door 2 in this position, the locking element 3 can be transferred via the starting bevel 6 from the release area 5.1 into the closing area 5.2. For movement of the locking element 2 in the guide 5, this is designed to be movable in two directions. The locking element 3 may initially in the slot formed as a recess 9 as shown in FIG Fig. 2 Move up and down relative to the recording 7. The receptacle 7 has a force acting on a housing 14 and designed as a compression spring spring element 8.

As shown in Fig. 1 the closing area 5.2 of the guide 5 has a run-on slope 6. When passing through the closing area 5.2, the locking element 3 must therefore also be able to move in an axial direction. Although this in the presentation of the Fig. 2 can not be seen, the locking element 3 in the axial direction by a Spring movably mounted. This spring is arranged in the housing 14, which can move together with the locking element 3 against the force of the spring element 8.

The guide 5 also has a blocking region 5.3, in which the locking element 3 is arranged in a locking position. Furthermore, the guide 5 has an opening region 5.4, which connects the blocking region 5.3 with the release region 5.1. On the various areas 5.1 to 5.4 and their functions in interaction with the locking element 3 will be described below with reference to the representations in the Fig. 3a to 3c will be discussed in more detail.

In the in Fig. 3a shown open position, the locking element 3 is initially in the release area 5.1 of the locking counterpart 4. In this position, the door 2 can be moved in the opening direction O and thus opened. To close the door 2, this and thus the locking element 3 is introduced via the run-on slope 6 in the closing area 5.2, as well as this with reference to the dashed path of movement in the Fig. 3b is indicated. During this movement, the locking element is moved against the force of the spring element 8 along the recess 9. As soon as the locking element 3 has reached the lower end of the closing area 5.2 and due to the spring element 8 as shown in FIG Fig. 3b has moved further to the left in the blocking area 5.3, a movement of the door 2 in the opening direction O and thus opening the door 2 by a tensile force is no longer possible. The shell-shaped configuration of the contour of the guide 5 in the blocking region 5.3 ensures that the locking element 3 can not move further in the recess 9 in the direction of the spring force.

If the door 2 is to be opened again, a force in the closing direction S must be exerted on the locking element 3. Through a movement of the locking element in the closing direction S, this will strike from the blocking area 5.3 to the outer contour of the opening area 5.4. By acting on the locking element 3 spring force this is further to the left along the dashed line in FIG Fig. 3c transferred from the blocking area 5.3 in the opening area 5.4 and then in the release area 5.1. As well as this in the representations of the Fig. 3a to c, the areas 5.2 to 5.4 are higher than the area 5.1. This results in that the locking element in the in Fig. 3a shown position during a movement in the closing direction S can not enter from the release area 5.1 in the opening area 5.4, but is retracted via the run-on slope 6 in the closing area 5.2. When crossing the corresponding edge 13, the locking element therefore moves in the direction of with respect to Fig. 2 described axial spring.

In the 4 and 5 is a mounting situation shown in a perspective view, wherein the locking counterpart 4 is arranged frontally in the fold of the door frame 2.2 and the receptacle 7 corresponding end face in a fold of the door leaf 2.1.

Like this in the Fig. 4 can be seen, is the closure device 1 in the illustrated installation situation in the locked position. Because the locking element 3 is in the restricted area 5.3 of the guide 5. In this position, it is therefore not possible to move the door 2 and the door leaf 2.1 relative to the door frame 2.1 by a tensile force. The two elements face each other in such a way that the locking element 3 moves in a movement of the door leaf 2.1 in the guide 5 of the locking counterpart 4, as described above. Although in the representations of the sake of clarity, both the locking counterpart 4 and the locking element 3 can be seen, these elements are so in the fold of the door leaf 2.1 or arranged in the door frame 2.2 that they are not visible from the outside and are covered by the door leaf 2.1, in particular by the outside door area above the door rebate.

In the presentation of the Fig. 5 is the same installation situation as in Fig. 4 but presented from a slightly different perspective. It can be seen that the receptacle 7 is embedded in a fold of the door leaf 2.1 and therefore requires only very little space in the gap between the door leaf 2.1 and the door frame 2.2. Only the locking element 3 protrudes beyond the contour of the door rebate, as for example in the illustration of Fig. 4 can be seen. By the arrangement of the receptacle 7 and the locking counterpart 5 according to the illustrations in 4 and 5 it is apparent that as far as possible, neither of the two elements protrudes into the clear opening of the door 2.

Although the closure device 1 prevents an opening of the door 2 on a tensile force, but it may happen that acts on the door 2 and the door leaf 2.1 an unintentional pressure force, which would then lead to an opening of the door 2. This can occur, for example, in fast tunnel trips especially with oncoming traffic when a pressure wave hits a door 2.

In order to prevent even in such situations, a cracking of the door 2, also in the 6 and 7 illustrated locking device provided. This is arranged on the inside of the door 2 and thus not visible from the outside. Once the door 2 has been closed, the locking element 3 is thus arranged in the blocking area 5.3, aligned an opening of the counterpart counterpart 12 with a bolt-shaped locking element 11 and this in the illustrations of 6 and 7 can be seen. By a linear movement of the locking element 11, this can engage in the locking counterpart 12 and thus opening the door even with a movement in the closing direction safely prevent. The blocking element 11 is connected at one end to a motor 15, which can move the blocking element 11 linearly. By this motor, the closure device 1 can therefore be locked. If the door is to be opened again, the blocking element 11 from the motor 15 from the in Fig. 6 shown position in the in Fig. 7 shown position transferred, so pulled out of the locking counterpart 12. This allows a relative movement between the locking counterpart 12 and the blocking element 11, so that a pressure force can be exerted on the door from the outside, the locking element 3 is transferred in the manner described above from the blocking area 5.3 in the release area 5.1 and the door are then opened can.
