Description

The invention relates to a cleaning device comprising a device body, a lid, a pivot bearing device, via which the lid is pivotally mounted on the device body, and a support device, via which the lid can be supported on the device body in a defined, open pivot position, the support device at least has a support element.

From the DE 44 37 244 A1 is a swivel armrest known for an omnibus seat.

The WO2010 / 018091 A1 discloses a floor care device and in particular household vacuum cleaner with a base body which has at least one space for a removable, mobile or detachable functional element such as a dust separator unit, filter device and / or accessory. There is at least one housing part which at least partially closes off the at least one space in the base body, the housing part being arranged articulated on the base body. An opening means is also provided which releases the at least one housing part from a closed position. Furthermore, there is at least one force-generating element which moves the housing part from its closed position via an opening path into an open position. The one or more force-generating elements are arranged outside the joint.

The invention has for its object to provide a cleaning device of the type mentioned, which has a structurally simple lid mechanism.

This object is achieved according to the invention in the cleaning device mentioned at the outset in that the support device has at least one support element and a web guide device assigned to the at least one support element The at least one support element comprises an element guided on the web guiding device, the web guiding device for the guided element having a first web and a second web, and at a transition region the second web adjoins the first web on the input side and the second web on the exit side into the first lane, and wherein a lock is arranged at the transition area, which allows entry of the guided element from the first lane on the entry side of the second lane into the second lane, blocks the exit of the second lane into the second lane on the exit side and releases the second lane into the first lane on the exit side of the second lane.

The web guiding device specifies a forced guidance for the guided element of the support element. A defined pivoting movement of the cover with respect to the device body can thereby be achieved.

The defined open swivel position can be secured and, for example, non-positively secured.

A protection against overpressing the cover can be easily formed.

A corresponding lid mechanism for opening the lid can be designed to be user-friendly with a small number of parts.

In particular, the web guiding device forms a sliding track and the guided element of the supporting element corresponds to a sliding block.

A defined open pivot position can be automatically secured simply by reaching the pivot position simply by reaching the pivot position.

In a structurally simple embodiment, the lock enables opening until a defined swivel position or closing of the cover is reached in a simple manner.

It is expedient if the lock is or comprises an inclined plane which rises towards the first lane and comprises a blocking area through which the first lane merges with the second lane on the input side of the second lane. This can be prevented in a simple manner that the guided element penetrates into the second web on the output side, in particular when the lid is opened, from the first web. Furthermore, it can be achieved in a simple manner that, in particular when the lid is closed, the guided element on the output side changes from the second path into the first path. This results in a defined positive guidance for the guided element and it For example, a defined swivel position can be secured in a simple manner. Both opening and closing can be carried out in a simple manner for an operator.

It is structurally advantageous if the blocking surface is formed on a wedge element which forms the inclined plane and which is arranged in particular in the second path. As a result, a lock can be formed in a simple manner while minimizing the required components.

It is advantageous if the second path forms a loop which is connected to the first path on the input side and on the output side. The lock ensures that the loop has a defined entrance and a defined exit in relation to the guidance of the guided element in relation to the first path. In this way, a forced guidance for the guided element can be achieved in a simple manner, which, for example, enables automatic securing of a defined pivot position of the cover to the device body.

It is expedient if the at least one support element is articulated in the region of a first end and the guided element is seated in the region of a second end which faces away from the first end. The guided element corresponding to a sliding block can then provide a corresponding forced movement of the cover with respect to its pivoting position and securing a defined pivoting position in a simple manner with a structurally simple design.

It is expedient if the at least one support element is pivotably articulated and the at least one support element is assigned a spring device which tends to pivot the at least one support element in a specific pivoting direction. This allows a defined pivot position to be fixed in a simple manner and, in particular, to be non-positively fixed. A force is required to lead out of the defined swivel position. This results in automatic operability. In particular this defined swivel position can be reached automatically. The spring device can be integrated in the support element and, for example, be formed by a corresponding inherent elasticity of the support element and / or a spring device separate from the support element and spring device acting on it, such as a spiral spring or the like, can be provided.

In particular, the determined pivoting direction is away from the device body. In this way, a defined pivot position can be fixed in a non-positive manner in a simple manner.

It is favorable if the first track has an at least approximately straight guide path for the guided element. In this way, an opening movement for the lid to the device body can be achieved in a simple manner.

It is also expedient if the second path has a decoupling area which is straight and leads on the output side into the first path and in particular the first path is a linear continuation of the decoupling area. As a result, a closing movement of the cover on the device body can be achieved in a simple manner with a structurally simple design.

In particular, the decoupling area is designed as a channel with opposing boundary walls. This makes it easy to form a loop in the second region. A positive guidance has been achieved, which prevents the guided element from escaping from the corresponding channel.

It is also expedient if the second area has a contact area which has a locking surface, the cover being fixed in the particular open pivot position when the guided element bears against the locking surface. This makes it particularly easy to non-positively secure a defined swivel position, which is supported by the support device. It is then advantageous if the second track on the contact area is designed such that a force is required to bring the guided element out of the contact area. This makes it easy to use.

In particular, the second track is formed on the contact area such that the guided element can be brought out of the contact area by pivoting the cover toward the device body with the application of force. This allows a defined swivel position to be held and supported in a simple manner and this can be canceled in a simple manner. In particular, it can then be provided that the pivoting towards the device body must again be carried out in a countermovement and then again pivoting towards the device body in order to be able to close the lid.

In an advantageous embodiment, the contact area is formed by a double trough area which has a first trough and a second trough, the first trough and the second trough being connected to one another, the blocking surface being formed on the first trough and an effort being required to transfer the guided one Element is required from the first trough into the second trough, and wherein the first trough is connected to a coupling-in area which is connected on the input side to the first area, and wherein the second trough is connected to a coupling-out area which leads on the output side into the first path .

A defined swiveling position of the cover relative to the device body can be held and supported in a simple manner via the first trough. By moving the first trough into the second trough, the lid can be easily returned to close the lid.

It is particularly advantageous if the force required to overcome a spring force is assigned to the at least one support element Spring device corresponds. As a result, a high level of operating convenience can be achieved while minimizing the number of parts required with a simple design.

It is particularly advantageous if the double trough area is designed as a channel with opposing boundary walls. In this way, a defined guidance of the guided element into the double recess area can be achieved, on the one hand to secure the defined pivot position and, on the other hand, to enable the defined pivot position to be released and the cover to be returned to a closed position by means of a defined guidance.

It is then advantageous if the second track has a coupling area which is connected on the input side to the first track. For example, the guided element can be brought into a double trough area via the coupling area. The coupling area can be designed in such a way that a defined positive guidance with corresponding pivotability of the cover to the device body is made possible.

It is expedient if the first region and / or the coupling region are designed as a channel with a boundary wall on one side. This minimizes, for example, the need to thread the guided element in these areas during the manufacture of the cleaning device.

For a positive guidance, it is favorable if the coupling area is oriented at an obtuse angle to the first area and in particular has at least one partial area with a straight path. In this way, optimized constraints can be achieved with regard to opening the cover and guiding it into a defined pivot position while securing this pivot position.

It can be provided that the support device is designed and arranged such that the cover automatically moves in from an unlocked position the defined open pivot position is movable or moves, and a pivoting toward the device body toward the device body with force is required to lead it out of the defined open pivot position. For example, such a spring action is provided on the support device that the automatic movement is made possible, or the support device has such a guiding configuration with respect to the guided element that, for example, a spring action on the swivel bearing device automatically flips the lid up to the device body until it is reached the defined open pivot position is made possible.

It is expedient if the support device is designed to be independent of gravity with regard to its support function. This results in a high level of operating comfort and the corresponding lid mechanism can be used in different places.

In one embodiment, the at least one support element is pivotally articulated on the device body and the web guiding device is arranged on the cover. However, a kinematic reversal is also possible, in which the at least one support element is pivotably articulated on the cover and the web guiding device is arranged on the device body.

In particular, the cleaning device is a suction device or comprises a suction device, the cover in particular being a filter cover cover. For example, it can be provided that the cover holds a filter cleaning device and also covers a filter device. It can alternatively or additionally be provided that the cover is relatively solid or heavy, because it can serve as a storage surface.

An embodiment of a cleaning device is a suction device, which in Figure 1 shown and designated 10, wherein in the Figures 2 to 10 Partial representations are shown.

The suction device 10 is, for example, a stand-alone suction device.

It comprises a suction container 12 with a receiving space 14. Dirt can be sucked into the receiving space 14 and picked up there directly or, for example, via a bag.

A suction head 16 is in particular detachably arranged on the suction container 12. A suction blower device is positioned on the suction head 16, which in Figure 1 is indicated by the reference numeral 18. The suction blower device 18 comprises a blower which generates the negative pressure required for a suction flow. The blower is driven by a motor and in particular an electric motor.

On the suction head 16 there is a suction connection 20 (cf. Figure 4 ) arranged. A suction pipe or a suction hose can be connected to the suction connection 20. The suction port 20 is in fluid-effective connection with the receiving space 14.

The suction head 16 has a device body 22. A pivotable cover 24 is arranged on the device body 22. The cover 24 is mounted on the device body 22 in the manner of a flap via a pivot bearing device 26 so as to be pivotable about a pivot axis 28.

In one embodiment, the device body 22 has a receiving space 30 for a filter device (not shown in the drawings). The receiving space 14 of the suction container 12 is acted upon by the suction flow via a filter device positioned in the receiving space 30. The filter device in the receiving space 30 ensures that suction material cannot be sucked into the suction fan device 18; the The filter device has a clean side toward the suction fan device 18 and a dirty side toward the receiving space 14.

In one embodiment, the suction fan device 18 is positioned adjacent to the receiving space 30 on the device body 22.

A raised strip 32 is arranged on the outside of the device body 22. The strip 32 can form a boundary wall for the suction fan device 18.

The pivot bearing device 26 is arranged on the bar 32. The suction connection 20 is arranged on the bar 32 or on a continuation of the bar 32.

The lid 24 is used to close the device body 22 to an upper side and thereby to close the receiving space 30.

In one exemplary embodiment, a filter cleaning device 34 assigned to a filter device in the receiving space 30 is arranged on the cover 24 (compare, for example Figure 4 ), which is used to clean the filter device.

When the cover 24 is closed, the filter cleaning device 34 can act on the filter device positioned in the receiving space 30 in order to carry out a filter cleaning.

An exemplary embodiment of a corresponding filter cleaning device 34 is shown in FIG WO 2012/107103 A1 to which express reference is made.

The filter cleaning device 34 is arranged on an inside of the lid 24, so that it can act on the filter device in the receiving space 30.

Additional components such as a control device (in Figure 1 indicated by the reference numeral 36).

The cover 24 is designed in cooperation with the device body 22 such that the corresponding components are arranged in a protected manner in an interior 38 of the suction head 16 when the cover 24 is closed.

The suction device 10 has a direction of height 40. If the suction device 10 is set up on a flat surface, then the direction of height 40 extends perpendicular to this surface.

The pivot axis 80 is transverse and in particular perpendicular to the direction of height 40.

The pivot bearing device 26 has a pivot bearing part which is arranged on the device body 22 and a further pivot bearing part which is arranged on the cover 24. This pivot bearing part on the cover 24 is positioned in the region of a first end 42 of the cover 24.

The suction head 16 has a locking device 44, via which a closed position of the cover 24 on the suction head 16 can be locked with the device body 22 ( Figure 4 ).

The locking device has a locking device part 46, which is arranged on the device body 22, and a locking device part 48, which is arranged on the cover 24. This locking device part 48 is arranged in the region of a second end 50 of the cover 24, which is remote from the first end 42.

The locking device 44 is formed, for example, by a snap lock.

The cover 24 is of relatively solid construction since it holds the filter cleaning device 34 and, if appropriate, also the control device 36. It can also be designed such that its upper side 52 is designed as a shelf. Accordingly, the lid 24 is relatively heavy.

To hold the cover 24 in a certain defined pivot position 54 ( Figures 1 and 7 ) to the device body 22, a support device designated as a whole by 56 is provided. The support device 56 comprises a web guide device 58 and a support element 60 ( Figure 2 ).

The support element 60 is, for example, a metal bracket.

The support element 60 is pivotally connected to the device body 22 in the area of the strip 32 via a pivot bearing 62. The pivot bearing 32 is in particular spaced apart from the pivot bearing device 26 in the vertical direction 40 and is positioned below the pivot bearing device 26.

A pivot axis 64 of the pivot bearing 62 is in particular parallel to the pivot axis 28 of the pivot bearing device 26.

A spring device 66 is assigned to the support element 60 ( Figure 2 ).

In one exemplary embodiment, the spring device 66 is an element which is separate from the support element 60 and which is arranged in the region of the pivot bearing 62.

In this embodiment, the spring device 66 is in particular a spiral spring.

It can also be provided that the spring device is integrated in the support element 60 and, for example, the support element 60 is designed to be inherently elastic and / or is arranged such that a corresponding spring force acts.

The spring device 66 is arranged and designed such that it exerts a force 68 on the support element 60 which tends to pivot the support element 60 away from the device body 22.

The support element 60 has a first end 70 and an opposite second end 72. The support element 60 is articulated to the device body 22 via the first end 70.

At the second end 72 there is an element 74 which is an element guided on the web guiding device 58. The guided element 74 forms a sliding block for a sliding track, which is formed on the web guide device 58.

The guided element 74 is, for example, a pin element which projects parallel to the pivot axis 64 on the support element 60.

The web guiding device 58 comprises a holder 76 which is fixed on the cover 24 in association with the support element 60. The holder 76 can be formed in one piece on the cover 24 or it can be a part separate from the cover 24 which is subsequently connected to the cover 24.

The web guiding device 58 comprises a first web 78 formed on the holder 76 and a second web 80 likewise formed on the holder 76 for the guided element 74.

The first track 78 is formed via a channel 82 which has a boundary wall 84 on one side. The boundary wall 84 is designed in particular in a straight line. It forms a guide for the guided element 74.

The channel 82 is open on a side 86, which lies opposite the boundary wall 84.

The channel 82 is also in an immersion direction 88 ( Figure 1 ), which is parallel to the pivot axis 28, open, so that the guided element 74 can dip into the channel 82 via the immersion direction 88.

In the exemplary embodiment shown, the channel has a channel base 90 formed on the holder 76, from which the boundary wall 84 projects transversely and in particular vertically.

The channel base 90 is not absolutely necessary for the functioning of the support device 58.

The first track 78 has an at least approximately straight guide section 92 ( Figure 3 ), which is in particular parallel to the boundary wall 84.

The guide section 92 is in particular at least approximately parallel to the upper side 52 of the cover 24.

Furthermore, the guide path 92 is at least approximately perpendicular to the height direction 40 when the cover 24 is locked with the device body 22 via the locking device 44, that is to say is closed.

The second track 80 has an entrance 94 and an exit 96. At the input 94, the first path 78 merges into the second path 80, that is to say on the input side, the second path 80 is connected to the first path 78 via the input 94.

At the exit 96, the second track 80 merges into the first track 78, that is, at the exit 96, the second track 80 is connected on the exit side to the first track 78.

The web guiding device 58 has a transition region 98, at which the first web 78 merges into the second web 80 and the second web 80 merges into the first web 78.

The second path 80 is guided in a loop 100 between the input 94 and the output 96, wherein it is connected to the first path 78 via the input 94 and the output 96.

The second path 80 has a coupling area 102 (coupling path), at which the input 94 is positioned; the coupling region 102 is connected on the input side to the first path 78.

The coupling region 102 is designed as a channel 104, which comprises a boundary wall 106 on one side. The boundary wall 106 is rectilinear. The channel 104 is open on an opposite side 108 of this channel 104.

The channel bottom of the channel 104 is formed by means of the channel bottom 90.

The coupling-in region 102 has a straight-line path guide 110 due to the straight course of the boundary wall 106. The boundary wall 106 is oriented at an obtuse angle 112 to the boundary wall 84. Accordingly, the straight-line path guide 110 is oriented to the guide path 92 at an obtuse angle 112.

In one embodiment, this obtuse angle 112 is in the range between 120 ° and 140 °.

A double trough region 114 (double trough web) adjoins the coupling region 102. This double trough region comprises a first trough 116, which is connected on the input side to the coupling region 102, and a second trough 118, which is connected on the input side to the first trough 116.

A decoupling area 120 (decoupling path) in turn adjoins the second trough 118.

The output 96 is arranged in the first path 78 at the decoupling region 120.

The decoupling area 120 is formed in a straight line with a guide section 122 which merges into the guide section 92.

The first path 78 forms a linear continuation of the decoupling region 120.

The double trough region 114 and the coupling-out region 120 have a first boundary wall 124a and an opposite second boundary wall 124b. Between these, a channel 126 is formed for the guided element 74, which is only open in the immersion direction 88.

The boundary wall 124b merges into the boundary wall 84.

The first boundary wall 124a is a continuation of the boundary wall 106 and forms a closed wall section with it.

Due to the boundary walls 124a, 124b arranged on both sides of the channel 126, the latter is laterally closed on both sides. A defined path guidance for the guided element 74 is thereby achieved.

A barrier 128 lies between the first trough 116 and the second trough 118 of the double trough region 114. In order to move the guided element 74 from the first trough 116 into the second trough 118, the barrier 128 (with the application of force, as will be explained in more detail below) be overcome.

The second boundary wall 124b has a course on the double trough region 114 which approximately corresponds to a W.

The opposite first boundary wall 124a is designed such that when the barrier 128 is overcome by the guided element 74, the latter is guided into the second trough 118, from where it is then possible to guide it into the decoupling region 120.

This is explained in more detail below.

The double trough area 114 has a contact area 130 which is formed on the barrier 128. The contact area 130 in turn has a blocking surface 132 on the barrier 128, this blocking surface 132 still being formed in the first depression 116.

An application of the guided element 74 defines an excellent pivoting position of the cover 24 relative to the device body 22, namely the defined specific pivoting position in which the cover 24 is held supported against the device body 22. A position of the guided member 74 engaging the locking surface 132 (in Figure 2 then designated by reference numeral 134) corresponds to the defined pivot position 54.

The spring device 66 is arranged and designed in cooperation with the support element 60 so that with this system 134 (the defined pivot position 54), the spring device 66 presses the guided element 74 against the locking surface 132.

In order to guide the guided element 74 away from the locking surface 132, that is to say to change the defined pivoting position 54, an effort is required by an operator, which is set by dimensioning and arranging the spring device 66.

The defined pivot position 54, in which an open position of the cover 24 is held and is supported on the device body 22 via the support device 56, is held non-positively via the spring device 56.

As will be explained in more detail below, starting from the swivel position 54 (with system 134 of the guided element 74 against the blocking surface 132), the guided element 74 can be moved out of the first trough by counter-pivoting in a direction 136 of the cover 24 towards the device body 22 116 lead out and led through the first boundary wall 174 (in Figure 2 an intermediate position 138 is shown), into which second trough 118 lead.

As a result, the “non-positive locking” is released via the system 134 in the defined pivot position 54 and the cover 24 can be closed.

The web guiding device 58 has a lock 140. The lock 140 ensures that when the guided element 74 is guided on the first path 78 at the transition to the second path 80 at the entrance 94, the guided element 74 cannot penetrate into the second path 80 at the exit 96.

It also ensures that when the guided element 74 is guided in the second path 80, it can pass into the first path 78 at the exit 96.

The lock 140 thereby ensures that the guided element 74 is “one-way guided” on the second path 80, that is, it specifies a guiding direction 142 for guiding the guided element 74 in the second path 80.

In the first track 78 there are two guide directions and in particular opposite guide directions for the guided element 74, while in the second track 80 there is only the single guide direction 142.

The lock 140 is formed by a wedge element 144, which is arranged in the second path at the coupling-out area 120 (the coupling-out path) at the exit 96. The wedge element 144 comprises an inclined plane 146 which lies in the second path at the decoupling region 120 and rises towards the exit 96, that is to say towards the first path 78.

The wedge element 144 also has a locking surface 148 at the transition region 98. This blocking surface 148 is connected in particular to the boundary wall 84 and the boundary wall 106.

The blocking surface 148 is designed such that when the guided element 74 is guided in the first path at the transition to the second path 80, entry into the second path is blocked at the exit 96. The blocking surface 148 guides the guided element 74 into the entrance 94 of the second lane 80 and prevents entry 96 into the second lane 80.

The blocking surface 148 has a corresponding height, which at the outlet 96 enables the guided element 74 to be lifted through the inclined plane 146 over the blocking surface 148 and thus introduced into the first track 78.

The wedge element 144 with the inclined plane 146 forms a channel floor at the second area 80 at the exit 96, which allows a transition of the guided element 74 from the second path 80 into the first path 78.

(Outside the wedge element 144, the boundary walls 84, 106, 124a, 124b in particular have a guiding function, so that a channel floor is not necessarily there necessary is. The channel base also has a guiding function on the wedge element 144.)

The support element 60 is mounted on the device body 22 and / or is designed such that transverse mobility caused by the wedge element 144 parallel to the immersion direction 88 is made possible in order to enable the transition from the second path 80 to the first path 78.

At the in Figure 1 In the exemplary embodiment shown, the support device 56 is arranged and formed on one side, that is to say only one holder 76 and only one support element 60 are provided.

In principle, it is also possible for the support device 56 to comprise, for example, a plurality of support elements 60 and a plurality of correspondingly arranged and formed web guides via holders 76.

In the suction device 10, the holder 76 with the web guiding device 58 is arranged on the cover 24 and the support element 60 is articulated on one side on the device body 22. In principle, a kinematic reversal is also possible, in which the web guiding device is arranged on the device body 22 and the corresponding support element 60 is pivotably articulated on the cover 24.

It can be provided that after the locking device 44 has been released, the cover 24 must be pivoted away from the device body 22 by appropriate force. Alternatively, it is also possible for the cover 24 to automatically pivot into the defined pivot position 54 after the locking device 44 has been released, without an operator having to intervene here. This can be achieved by appropriate design of the support device 56 and in particular arrangement and design of the spring device 66.

As an alternative or in addition, it is also possible for a corresponding spring device to be arranged on the swivel bearing device 26, which ensures that it is opened up to the defined swivel position 54.

The support device 46 functions as follows, the mode of operation being based on FIG Figures 4 to 10 is explained:
Starting from a closed position of the cover 24, in which the cover 24 is locked to the device body 22 via the locking device 44 ( Figure 4 ), the locking device 44 is released and then the cover 24 is pivoted in a direction 150.

Depending on the embodiment, as mentioned above, the cover 24 must be pivoted in the direction 150 by operator intervention, or the cover 24 pivots automatically away from the device body 22.

In Figure 5 an intermediate position is shown during this pivoting movement. A distance 152 between the cover 24 and the device body 22 increases.

When swiveling further in the direction of 154 according to Figure 4 the distance increases further; in Figure 6 another intermediate position is shown.

With a further pivoting 156 according to Figure 6 then finally the defined pivot position 54 is reached.

In the defined pivot position 54, the cover 24 is held in a defined position in a force-locking manner and is supported by the support device 56 with respect to the device body 22.

In the defined pivot position 54, the receiving space 30 can be accessed in particular, for example, to replace the filter device.

In the closed position according to Figure 4 the guided element 74 is positioned on the support element 60 in the first path 78. Due to the pivoting in the direction 150, the guided element 74 is guided along the first path 78 by lifting the cover 24 (operator-guided or automatically). This is in Figure 2 indicated by the arrows with the number 1.

If the intermediate position according to Figure 5 is reached, then the transition area 98 of the web guiding device 58 is reached by the guided element 74. By pivoting 154 further, the guided element 74 "penetrates" the second path 80 at the entrance 94. The second track 80 is designed in such a way that pivoting up is made possible.

The lock 140 guides the guided element 74 into the second path 80 at the entrance 94 and prevents penetration of the guided element 74 into the second path 80 at the exit 96.

By pivoting 154 and then pivoting 156, the guided element 74 is guided in the second path 80 and then brought into the first depression 116 of the double depression region 114 ( Figure 7 ).

The corresponding leadership is in Figure 2 indicated in the second lane 80 by arrows with the number 1.

In the double trough area 114, the guided element 74 then lies against the blocking surface 132 (reference numeral 134 according to FIG Figure 2 ) and the defined pivot position 54 is secured.

The slide track of the web guide device 58 is designed such that further pivoting in the same direction is not possible; barrier 128 prevents this.

To close the cover 24, starting from the open position, i.e. the defined pivot position 54 ( Figure 7 ), a counter-pivoting movement 158 ( Figure 7 ) carried out. This requires an effort, which in Figure 7 is indicated by reference number 160.

This effort 160 essentially corresponds to overcoming the spring force of the spring device 66.

The effort 160 must be applied by an operator.

The counter-pivoting movement 158 with the expenditure of force 160 causes the guided element 74 to be guided out of the first depression 116 while overcoming the barrier 128 and is thereby guided into the second depression 118 via the first boundary wall 124a.

The corresponding leadership is in Figure 2 indicated by arrows with the number 2.

In Figure 8 A corresponding intermediate position is shown, in which the guided element 74 rests on the first boundary wall 124a (position 138 according to FIG Figure 2 ).

By pivoting 162 the cover 24 away from the device body 22, the guided element 74 can then be brought into the second trough 118 and from there into the decoupling area 128.

By pivoting 164 of the cover 24 towards the device body 22, the guided element 74 can be guided in the decoupling area 120 and guided through the lock 140 into the first path 78.

This is in Figure 2 indicated by the arrows with the reference number 2.

The lid 24 can then be closed and locked with the device body 22 via the locking device 44.

The cover 24 has a further excellent position 166 relative to the device body 22 ( Figure 9 ), in which the guided element 74 lies in the second depression 118. In this excellent position 166, the cover 24 has a largest swivel angle with respect to the device body 22.

Starting from the excellent position 166, the cover 24 can be closed by swiveling onto the device body 22.

Operator intervention is required in order to reach the excellent position 166 from the defined pivot position 54. First, starting from the defined swivel position 54 ( Figure 7 ) a pivoting in the counter-pivoting direction 158 is carried out so that the position of the guided element 74 according to Figure 8 is reached. A pivoting in the other direction, that is to say in the direction 162, must then again be carried out in order to bring the guided element 74 into the decoupling region 120.

It can be provided that the coupling-out area 120 is designed in cooperation with the first track 78 in such a way that when the coupling-out area 120 is reached, the cover 24 closes by itself, or in order to prevent just such a clipping, a design can be provided be, in which a certain amount of force is necessary to achieve a pivoting of the lid 24 to the device body 22.

The support device 56 defines a forced guidance of a pivoting movement of the cover 24 towards the device body 22.

A defined pivoting position 54 can be achieved by the support device 56, in which the cover 24 is supported in relation to the device body 22 is held. In particular, the cover 24 is non-positively fixed in the defined pivot position 54 by the positive guidance.

It can be achieved in a simple manner via the web guide device 58 in cooperation with the support element 60 to secure the cover 24 from being pressed.

It is easy to achieve an optimized lid mechanism with regard to an opening movement and a closing movement with a small number of components and with a structurally simple design.

The support device 56 can be designed with little wear.

User-friendly access to the receiving space 30 can be realized.
