Description

Vorrichtung zum Halten und Lösen eines Stellelements sowie Verfahren zum Betätigen einer solchen VorrichtungDevice for holding and releasing an actuating element and method for actuating such a device

The invention relates to a device for holding and releasing an actuating element with a link and a method for actuating such a device.

From JP H08-11503 A an adjusting device is known by which a provided in a chair leg or on a piece of furniture footer is transferred from a use position to a non-use position. This adjusting device has an actuating mechanism which is formed by a lever arrangement with two adjusting elements. The two adjusting elements are arranged opposite to each other, wherein a spring element provided between the adjusting elements presses the adjusting elements in each case in a sliding guide on the foot element. An additional spring mechanism engages the displaceable foot element and causes an adjusting movement of the foot element due to the spring force. In this adjusting movement arranged on the foot element backdrop performs a relative movement to the mounted on the lever assembly actuators, wherein the lever assembly is fixedly mounted on the chair leg. In an upper and a lower detent position in the slotted guide, the foot element occupies the use or non-use position.

From JP 2006-188 112 A, an adjusting device for transferring a roll from a use position to a non-use position emerges. This adjusting device is provided for attachment to a piece of furniture, so that the piece of furniture can be easily moved by transferring the rollers to the use position, whereas the piece of furniture assumes a firm footing when the roll is arranged in the non-use position. This adjusting device has a slotted guide for an actuating element, which is formed in a circular manner along a cylindrical wall of a housing of the adjusting device. When executing an actuating movement, the actuating element alternately assumes the use and non-use position, wherein this performs a continuous rotational movement in the cylindrical slotted guide.

From CN 2012 00131 Y a device for opening and closing a drawer of a piece of furniture is known in which an adjusting element is received in a heart-shaped backdrop and connected via a rod-shaped connecting element with the drawer, wherein the connecting element is also guided in a further guide. Between the connecting element and a side wall of the piece of furniture designed as a tension spring spring element acts. When closing the drawer, the spring element is stretched and moved the actuator along a guide path in the backdrop and taken up and held in an end position formed by the heart curve. When opening the drawer, the holding element is released from the end position and transferred along a second guide along the gate to a second end position, whereby the drawer is automatically opened via the connecting element due to the spring force.

The invention has for its object to provide a device for holding and releasing a control element in a backdrop, in which an adjusting movement of the actuating element in the backdrop is executable without an additional power storage element engages the actuator or is connected to the actuator.

This object is achieved by a device for holding and releasing an actuating element comprising a circumferential link and a central part, wherein the link and the middle part form a slotted guide in a plane in the main extension direction, in which the adjusting element between at least a first end position and at least one second or Another end position is movable, solved, in which the link is formed as a hollow backdrop, which comprises a one-sided mounting of the actuating element and the actuator has at least one guide element through which the actuator in or along the slotted guide by engaging or engaging behind the at least one guide element in or guided on the hollow backdrop and the middle part movable and kept tilting. As a result, a simple and compact construction of the device can be achieved, which can be used very flexibly in various fields of application. This device may also comprise a plurality of end positions for the actuating element, by means of which the actuating element can assume different positions in order to fulfill different functions or tasks in these positions. The one-sided bearing of the actuating element is formed by the fact that only one bearing point is provided on the adjusting element, which is arranged in a lateral region of the actuating element or an end region of the actuating element and inserted in the slotted guide. As a result, an area lying opposite the bearing area is formed on the adjusting element, which protrudes freely with respect to the hollow slot and is provided, for example, for receiving a device or the like. By the at least one guide element, a guiding and holding function is achieved, by which the adjusting element is held in the slotted guide and guided without tilting. The one-sided storage of the control element in the hollow backdrop allows a simple structural design and a low overall height of the device.

In a preferred embodiment of the device, the actuating element has at least one guide element at one end and the at least one guide element is supported on one side by reaching into the hollow slot and the middle part or by engaging behind the hollow slot and the middle part and faces with its other end Sliding guide freely out. As a result, an actuating element is formed, which is held in or on the hollow backdrop and the middle part and freely movable along the slotted guide and can also be held in a rectangular position to the slotted guide.

An advantageous development of the device provides that the encircling hollow slotted member and the middle part has a slot-oriented groove aligned with the slotted guide and in which groove the at least one guide element is guided. By this configuration, a one-sided guide and bearing of the actuating element is formed, in which the guide element engages in the groove and is held securely. Through the groove, the actuator can also be performed without tilting with only one provided on the actuator guide element, and tilting of the actuator in any position along the slotted guide to be prevented. The device can be formed in this embodiment with a very low height.

In an alternative embodiment of the device is provided that the hollow backdrop and the middle part are arranged on a housing, between the housing on the one hand and the hollow backdrop and the middle part on the other hand, a cavity is formed, which is accessible through the slotted guide from the outside and that at least a guide element is positioned in the cavity and engages behind the hollow backdrop and the middle part. By this configuration, a stable guide for the actuator is created in which high loads can be transmitted to the hollow backdrop and the middle part by the actuator. Nevertheless, this embodiment of the device allows a tilt-free guidance of the actuating element, in which this is movable without tilting along the slotted guide.

The at least one guide element is preferably substantially disc-shaped, extends radially outward relative to the actuating element and preferably forms at least one contact surface, which is arranged adjacent to the hollow slide and the middle part. The disc-shaped guide elements avoid tilting or snagging on or in the hollow slot and the middle part, whereby a safe and low-friction running of the control element is given. Due to the contact surface, the control element is also held in a direction perpendicular to the slide guide or rectangular position and prevents tilting.

The actuator advantageously has two guide elements, which form an H-shaped guide of the actuating element on the hollow backdrop and the middle part. Preferably, two mutually parallel guide sections are formed on the actuating element. As a result, surface portions between the guide elements and the hollow backdrop and the central part are formed, which can absorb a tilting moment of the actuating element at a load occurring thereon.

The preferred embodiment of the H-shaped arranged guide elements of the bearing area of the actuating element is limited, which is guided along the link guide, so that the hollow slot and the middle part is arranged between the guide elements. Through the two guide elements, a low-play traversing movement of the actuating element can be formed in the slotted guide.

The at least one guide element is advantageously releasably connected to the actuating element or integrally formed with the actuating element. As a result, the control element can be manufactured either from a plurality of individual parts, which are assembled in a further manufacturing or assembly step to form a component or alternatively manufactured as a component. A one-piece design of the control element can provide a higher strength of the control element.

A preferred embodiment of the invention provides that the adjusting element is designed as an axle body, which is slidably guided at least in the slotted guide with a circular cross-section. Through the formation of a round axle body, the adjusting element can roll along the sliding guide during the movement and be guided without tilting or snagging. In addition, the rotationally symmetrical, round axle body can be recorded secured in an end position in each rotated position.

In a preferred embodiment, an axle extension is provided on one of the at least one guide element opposite end of the actuating element, which protrudes freely against the slotted guide and for receiving a device, in particular an object, wheel, foot, hook, eye or lever is provided. This opposite to the slotted guide axle extension is formed by the one-sided leadership of the actuating element, in which the actuating element is mounted on one side on the hollow backdrop and the middle part. By this one-sided guidance of the adjusting element, any objects can be arranged on the bearing opposite the axle extension, which can be transferred by the adjusting movement of the actuating element, for example, from a non-use position to a use position and vice versa.

It is particularly preferably provided that the at least one end position of the adjusting element is formed on the hollow backdrop by at least one funnel-shaped or U-shaped receptacle, which preferably has a rounding. Through the funnel or U-shaped recording can be made possible a quick and secure capture of the end position of the control element. Due to the round design of the receptacle, a snug fit for the actuating element can be formed, whereby neither wedging nor jamming of the actuating element takes place in the end position. The actuator can thus be brought out again without additional force from the recording.

In a further preferred embodiment, it is provided that the at least one end position of the adjusting element is formed at the central part by at least one funnel-shaped or U-shaped receptacle, which preferably has a rounding. As a result, the same advantages as in the recording of the hollow backdrop are achieved. Both at the hollow backdrop and at the middle part also several end positions can be formed in series one behind the other. As a result, end positions of the adjusting element can be arranged offset next to one another and / or at different heights. It can be formed a kind of sawtooth course. This can be given a high variability of the device, so that different use and non-use positions and intermediate positions can be taken. The slotted guide can be formed entangled heart-shaped.

It is preferably provided that the central part has a substantially heart-shaped shape and together with the hollow backdrop a substantially heart-shaped slotted guide is formed, preferably with a vertical orientation of the plane of the main extension direction of the hollow backdrop, the top of the heart points upward. Thereby, a slotted guide with two end positions for the actuator can be created, wherein the one end position at the top of the heart and the second end position opposite, formed by lying between the two halves of the heart notch at the middle part. In this vertical orientation of the device, the one end position at the tip may be referred to as an upper end position and the second end position as a lower end position for the actuator.

In a further preferred embodiment of the invention, the actuating element is freely movable between at least one first end position and at least one second end position. This allows a simple construction of the device, without an additional force element, such as a force accumulator, spring element or the like can be achieved.

Preferably, the actuator is by the action of gravity on the actuator along a first guide path of the slotted guide from the first or upper end position movable into a first intermediate position and then acting by a gravity opposing acting force on the hollow backdrop along a second guide path from the first Intermediate position in the at least one second or lower end position movable. The actuating element can be movable between the first end position and the second end position without the action of an additional force element provided on the device, by a force acting on the device from the outside.

Furthermore, the actuator is preferably by action of gravity on the actuator along a third guide path of the slotted guide from the at least one second or lower end position movable to a second intermediate position and then acting by a gravity opposing acting force on the hollow backdrop along a fourth guide path from the second intermediate position in the first or upper end position or in a further end position movable.

The adjusting movement of the adjusting element in the slotted guide can take place in a forced circulation according to a one-way street principle, so that the adjusting element always follows the same direction of rotation during the adjusting movements. As a result, an error-free operation of the device is achieved by forcibly taking the successive end positions. The adjusting movement of the actuating element can take place both in the clockwise direction and counterclockwise.

In a preferred embodiment of the device is provided that the hollow gate and / or the middle part are arranged on a housing and are preferably screwed to this, clipped, glued or molded. This type of arrangement on the housing offers the advantage of a high variability of different objects. In addition, the multi-part embodiment has the advantage that individual components can be manufactured separately and then by the above-mentioned connection options, for example, immediately before use, can be assembled. This offers the further advantage that the device can be disassembled for maintenance and repair purposes and in case of damage to individual components they are interchangeable.

An alternative embodiment of the device provides that the hollow backdrop, the middle part and the housing are integrally formed. As a result, manufacturing costs can be saved. In addition, the one-piece design of the device can achieve higher strength values of the device, which can withstand these higher loads.

A preferred application of the invention provides that the housing is arranged on an object, object or container and is preferably screwed, clipped, glued or molded onto this or is formed integrally therewith. Due to the different mounting options, the device is flexibly attachable to different objects, objects or containers. The one-piece design of the housing with the object, object or container additionally offers the advantage that even at the object, object or container is given the opportunity to attach the hollow backdrop and the middle part directly to it. In addition, an additional connection between the device and the object, object or container is avoided by the one-piece design of the housing with the object, object or container.

Particularly preferably, it is provided that the adjusting element is arranged in the at least one second or further end position in a use position and in the at least one first end position in a non-use position or vice versa. Thus, both the first and the second end position can represent a position of use for the actuator or arranged on the axle extension device, whereby the device has a high flexibility and can be used for a variety of uses.

According to an advantageous embodiment of the invention, it is provided that at least one left and at least one right hollow backdrop and middle part are provided on the object, object or container, wherein the hollow backdrop and the middle part in mirror image on two opposite sides of the housing, object, object or container are arranged and the two arranged separately from each other and guided in the respective slotted guide actuators in the at least one first and / or the at least one second end position are arranged on a common virtual axis. As a result, a special functionality of the object, article or container in connection with the device can be achieved, since during the transfer of the adjusting elements from the first or second end position into the second or first end position, a use position or a non-use position can be assumed. For example, if a wheel is provided on the actuator, the object, article or container may be brought, for example, in a raised condition relative to the ground or ground, thereby transferring the wheel from the non-use position to the use position and the object, the object or the container is movable. The same applies to an actuator arranged on the foot, lever or the like.

The object underlying the invention is further achieved by a method for actuating a device for holding and releasing an actuating element, in particular according to one of the above-described embodiments, in which a substantially upward vertical change in position of a hollow backdrop, the actuator by the action of gravity is moved from at least a first end position along a first guide path in a first intermediate position and is moved by a subsequent, substantially downwardly directed vertical change in position of the hollow backdrop, the actuator from the first intermediate position in at least a second end position.

In a subsequent adjusting movement of the adjusting element, this is moved by a substantially upward vertical change in position of the hollow backdrop by gravity from the at least one second end position along a second guide path in a second intermediate position and by a subsequent, substantially downwardly directed vertical change in position of the hollow backdrop, the actuator is moved from the second intermediate position in the at least one first end position or a further end position. The different end positions different usage positions and / or non-use positions and possibly intermediate positions can be taken, which may have a lateral offset to each other and / or may represent different altitudes for the actuator. Depending on which object, object or container the device is arranged and which device, such as an object, wheel, foot, lever, hook, eye or the like is arranged on the axle extension of the actuating element, either the first end position or the second end position a Use or non-use position.

FIG. 1 shows a view of a device 10 according to the invention, which comprises a hollow slotted part 11 and a middle part 12. Through the middle part 12 and the hollow backdrop 11, which lie in a common plane, a circumferential slotted guide 13 is formed, along which an adjusting element 14 is arranged, for example, in two

end positions

16, 17 movable. In Figure 1, a bearing portion 38 of the adjusting element 14 is shown as a cylindrical actuating element 14 by way of example in a first end position 16 of the guide slot 13.

The slotted guide 13 forms a positive guide for the adjusting element 14, which is guided circumferentially, for example, clockwise. The first end position 16 is formed, for example, by the hollow slot 11, on which a funnel-shaped or U-shaped receptacle 25 is preferably formed. A first guide path 26 is formed between the first end position 16 and a first intermediate position 18 remote therefrom. Along a second guide path 27, which has an opposite direction of travel of the adjusting element 14 to the first guide path 26, the adjusting element 14 from the first intermediate position 18 in a second end position 17 can be transferred. The second end position 17 is formed on the middle part 12 by a funnel-shaped or U-shaped receptacle 21 which, like the receptacle 25, preferably has a round seat whose radius substantially corresponds to the diameter of the bearing area 38 of the actuating element 14. From the second end position 17, the adjusting element 14 is movable along a third guide path 28 in a second intermediate position 19, wherein the direction of movement reverses. From the second intermediate position 19, the adjusting element 14 along a fourth guide path 29 back to the first end position 16 can be moved. The Verfahrbewegungsrichtung along the fourth guide path 29 is in turn opposite to the third and first guide path 28, 26th

FIG. 2 shows the embodiment according to the invention of the device 10 in a sectional representation according to the section A-A in FIG. 1, in which the adjusting element 14 is inserted into the slotted guide 13. The device 10 has a housing 22, on which a peripheral frame 23 and a centrally arranged web 24 are provided. At the provided on the edge of the housing 22 frame 23, the hollow slit 11 is arranged, which is screwed to the frame 23, clipped, glued or fixed by an equivalent acting fixation on this.

The middle part 12 is attached to the centrally arranged web 24, wherein the middle part 12 is screwed, clipped, glued or fixed by an equivalent-acting fixation on the web 24 at this. The housing 22 and / or the hollow gate 11 and / or the middle part 12 may alternatively be configured in one piece.

The frame 23 and the web 24 are configured in such a way that between the hollow gate 11 and the central part 12 on the one hand and the housing 22 on the other hand a distance is formed, so that the housing 22, the hollow gate 11 and the central part 12 in the assembled state, a cavity Train 30. The frame 23 and the web 24 are also formed in such a way that a surface 41 is formed by the hollow slot 11 and the central part 12, which acts as an undercut for the actuating element 14.

In addition to Figure 2, the actuator 14 is shown in perspective in Figure 3. The adjusting element 14 is substantially formed by an axis 31, wherein at the one end of the axis 31, a first guide member 32 is provided and adjacent to a second guide member 33, so that between the guide elements 32,33 a bearing portion 38 is formed in the Slotted guide 13 is arranged.

Both guide

elements

32, 33 are disc-shaped and formed in cross section larger than the axis 31 in the bearing area 38 and each have a

contact surface

34, 36, which point to each other. In this illustration, the diameter of the first guide member 32 is smaller than the diameter of the second guide member 33. Alternatively, both diameters of the

guide members

32, 33 may be the same size or the diameter of the second guide member 33 is smaller than that of the first guide member

32nd Die Führungselemente

32 , 33 may also have other geometric shapes. For example, these may consist of any number of arms that point away from the axis 31 in a star shape. The distance between the contact surfaces 34, 36 of the

guide elements

32, 33 is slightly larger than the wall thickness of the hollow slotted part 11 and the middle part 12, so that a low-backlash guide is formed. The one guide element 32 engages in the cavity 30 and is guided therein along the surface 41 acting as an undercut. The further guide element 33 is guided with its contact surface 36 along an outer side of the hollow slide 11 and the middle part 12. The bearing area 38 is provided between the

guide elements

32, 33 of the actuating element 14 in the slotted guide 13. By the two

abutment surfaces

34, 36, which rest on both sides of the hollow slot 11 and the middle part 12, the actuating element 14 is held in a tilt-stable position.

The axis 31 and the

guide elements

32, 33 may be integrally formed or represent separate parts, wherein the

guide elements

32, 33 are placed or pushed onto the axis 31 and connected to the axis 31.

The adjusting element 14 additionally has an axle extension 37 which protrudes freely with respect to the second guide element 33. This axle extension 37 serves for example for receiving an object, such as a wheel (40), foot, lever, hook, an eyelet or the like. A bearing 39 can be mounted on the axle extension 37 in order to support, for example, the wheel (40) rotatably on the axle extension 37.

In the first embodiment of the device 10 according to FIG. 1, the slide guide 13 formed by the hollow slide 11 and the middle part 12 has the shape of a heart curve. The device 10 may be vertically aligned when used according to the orientation, with the tip of the heart-shaped slide guide 13 facing upward. This results in the following operation:

In this vertical orientation of the device 10, the first end position 16 of the actuating element 14 can be regarded as the upper end position. In the receptacle 25 of the first or upper end position 16, the adjusting element 14 is received with little play, so that the adjusting element 14 is held by an opposing gravity G directed force F on the actuating element 14 in the receptacle 25.

From the first end position 16, the actuating element 14 is movable by the action of gravity G along a first guide 26 of the slide guide 13 in a first intermediate position 18, for example, by the housing 22 is raised with the hollow slide 11 and the middle part 12. During the adjusting movement, the adjusting element 14 initially executes a vertically downwardly pointing adjusting movement starting from the first end position 16 and strikes a first oblique edge 42 of the middle part 12, by which the adjusting element 14 forcibly moves obliquely in an obliquely from the vertically downward movement direction Directed right below directed direction of movement. This forced deflection of the direction of movement to the process along the first guide path 26 is achieved in that the middle part 12 has a heart shape, in which the tip 45 of the central part 12 facing upward. According to an illustrated in Figure 1, adjacent to the top 45 of the heart-shaped central portion 12 first construction line 65, the tip 45 of the central part 12 is laterally offset to the left with respect to a vertical line of the first receptacle 25 on which, for example, the arrow of gravity G is located. The sloping edge 42 at the central portion 12 extends in an area between the first construction line 65 and a second construction line 66 delimiting the right area of the receptacle 25. Preferably, the sloping edge 42 extends to the right beyond the construction line 66. The actuator 14 falls in a vertical direction of movement of the receptacle 25 on the first inclined edge 42 of the heart-shaped central portion 12 and is thereby passed into the forced circulation of the slide guide 13. A movement in the fourth guide 29 is prevented.

At this oblique course of the slotted guide 13 is followed by a vertically downwardly facing portion of the slotted guide 13. This ends in a second inclined portion of the slotted guide 13, which is opposite to the first inclined portion with the edge 42 inclined, and which deflects the adjusting element 14 in the first intermediate position 18. The first end position 16 and the first intermediate position 18 can lie on a common vertical line. The first intermediate position 18 is formed by a first sawtooth-like shaped nose 44 of the hollow slot 11, which is arranged laterally offset to another, mirror-image provided on the central portion 12 sawtooth-like nose 46, from which a further oblique edge 47 extends to the receptacle 21. According to a third construction line 67, which extends through the nose 46 and which may be an extension of the second construction line 66, the nose 46 is offset laterally to the right relative to the intermediate position 18, so that the adjusting element 14 moves vertically upwards always hits the sloping edge 47 and is not moved back into the first guide path 26. By this staggered arrangement of the sawtooth-

like lugs

44, 46, the actuator 14 in the vertically upward movement of the actuating element 12 along the second guide path 27 of the oblique edge 47 of the sawtooth-like nose 46 of the central portion 12, in a direction pointing to the left in FIG the second end position 17 forcibly deflected in the receptacle 21. This movement can take place, for example, by lowering the housing 22 with the hollow slide 11 and the middle part 12 in relation to a control element 12 which is held or abutted on an abutment.

In a subsequent vertically downward movement of the actuating element 14 - again by lifting the housing 22 with the hollow slot 11 and the middle part 12 - this meets an oblique edge 48 of the first sawtooth-like nose 44, which deflects the direction of movement of the actuating element 14 to the bottom left and the adjusting element 14 leads into the second intermediate position 19. The nose 44 is arranged in such a way to the receptacle 21 that extends through the nose 44 construction line 68, which may be an extension of the construction line 65, offset to the right to the receptacle 21, so that it is ensured that the actuating element 14 at the vertically downwardly directed movement is forcibly deflected into the third guide path 28 and is not moved into the second guide path 27. The second intermediate position 19 is offset relative to a further construction line 69 extending on the central part 12 to the left. From this, an inclined flank 71 provided on the central part 12 leads into the fourth guide path 29, so that the actuating element 14 is forcibly guided out of the second intermediate position 19 into the upward-pointing section of the fourth guide path 29 and is not moved back into the third guide path 28. The adjusting element 14 is moved to a further oblique section of the fourth guide path 29, and guided along an edge 63, which acts analogous to the

flanks

42, 47, 48. At the end of the fourth guide path 29, the actuator 14 enters the first receptacle 25 of the first end position 16. From this first end position 16 of the above-described forced circulation can be done again.

The device 10 may also be mirror-inverted in a left and / or a right embodiment, so that the previously described changes in direction of the adjusting movement of the actuating element 14 are each performed mirror-inverted.

FIG. 4 shows an alternative embodiment of the device 10 in FIG. 1. In this embodiment, a circumferential groove 64 is provided on the hollow slot 11 and the middle part 12, which points to the slot guide 13. At this adjusting element 14, only one guide element 32 is provided in comparison to the adjusting element 14 according to Figures 2 and 3. Incidentally, the embodiments and alternatives described above also apply to this adjusting element 14. This guide element 32 is also configured disc-shaped, so that the guide element 32 engages in the groove 64 of the hollow slot 11 and the middle part 12 when the adjusting element 14 is inserted into the slotted guide 13 , By the guide member 32, two mutually facing bearing surfaces 34, 36 are formed, which rest against the side walls of the groove 64 and hold the actuator 14 in a tilt-stable position. The groove 64 is configured circumferentially in the hollow slot 11 and the middle part 12 along the slotted guide 13, so that the adjusting element 14 along the circumferential slotted guide 13 is movable and held in a rectangular orientation to the slotted guide 13.

In this embodiment of the device 10, the hollow gate 11 and the central part 12 can be mounted directly on a flat surface of the housing 22, without a cavity 30 must be provided. As a result, a much lower overall height of the device 10 is given. The housing 22 facing the front side of the axis 31 of the actuating element 14 may be offset slightly back relative to the housing 22, so that the end face is within the slide guide 13.

FIG. 5 a shows an arrangement of four devices 10 according to the invention on a container 61, in particular for the transport of objects or the like, two devices 10 being mounted in pairs opposite the container 61. The adjusting elements 14 are in pairs opposite each other in the respective end positions 16, 17 on a common virtual axis 62. As a result, a movable carriage is formed on which four wheels 40 are extendable for use, whereby a tilt-stable stand is formed. For a non-use of the wheels 40 or a secure resting arrangement of the container 61, the wheels 40 are retractable, so that the container 61, for example, during transport in a motor vehicle rests on the floor and does not slide back and forth. In this figure, the adjusting elements 14 are shown in the first and upper end position 16, in which the wheels 40 are arranged in the retracted position. Alternatively, only two devices 10 can be arranged on the container 61, as shown in FIGS. 5c and 5d. Likewise, a plurality of wheels 40 can be attached.

In the device 10 according to FIG. 5 a, the housing 22 also has a wedge-shaped form, as can be seen from FIG. 5 b. As a result, the device 10 is adapted to an oblique side wall of the container 61 and can be arranged and the slotted guide 13 is vertically aligned despite the oblique side wall.

The four devices 10 are arranged on two opposite sides of the container 61, wherein on one side of the container 61 in each case two left and on the opposite side two right embodiments of the device 10 are provided. This means that the devices 10 are mirror images of each other. In this arrangement, the devices 10 are also mounted at the same height on the sides of the container 61, so that in each case the two opposing control elements 14 of the devices 10 are arranged at least in the second end position 17 on a common virtual axis 62. In a symmetrical design of the opposing devices 10 are the respective adjusting elements 14 of the opposing devices 10 both in the first end position 16 and in the second end position 17 on the common virtual axis 62. The control elements 14 take, for example, wheels 40 (FIG 4). These have a diameter so that they do not touch the ground when positioning the adjusting elements 14 in the first end position 16, on which the container 61 rests and lift the container 61 from the ground, provided that the adjusting elements 14 are arranged in the second end position 17. In this way, the container 61 can be moved on the wheels 40 movable.

FIG. 5b shows a front view of the container 61 according to FIG. 5a. From this it can be seen that the devices 10 are arranged on the two opposite sides of the container 61 and that the opposite wheels 40 are located on the common axis 62. The wheels 40 are arranged in this representation in the non-use position, in which they are in a raised state relative to the ground, so that the bottom of the container 61 rests on the ground.

FIG. 5c shows a side view of the container 61 with one or both devices 10 according to FIG. 5a in the non-use position. The adjusting element 14 is arranged in the first or upper end position 16. In this non-use position, the wheels 40 are in a raised condition relative to the ground and do not touch the ground. The container 61 is thus slipping on the ground.

In Figure 5d, the container 61 is in a use state in which the adjusting element 14 is arranged in the second or lower end position 17. In this position of use, the wheels 40 are placed on the ground and the container 61 raised by the height h from the ground. In this position of use, the container 61 can be moved.

Compared to the slotted guide 13 according to FIG. 1, the slotted guide 13 of this alternative embodiment of the device 10 according to FIG. 6 has a modified construction in which a third sawtooth-like nose 52 is provided on the middle part 12 and corresponding to this on the hollow slat 11 a fourth sawtooth-like Nose 53 is formed, which is arranged laterally offset from the third nose 52 on the central part 12. As a result, the adjusting element 14 is guided by a vertically upwardly directed adjusting movement from the second intermediate position 19 via an oblique edge 72 of the nose 52 first into a third end position 51, from which the actuating element 14 by a vertically downward positioning movement by a further oblique edge 73 of the fourth nose 53 is guided in a third intermediate position 54. For this, the adjusting element 14 along the fourth guide path 29 can be converted by a vertically upward adjusting movement back into the first end position 16.

This alternative embodiment of the additional receptacle 49 on the central part 12 and the corresponding adaptation to the hollow backdrop 11 can be continued as desired, so that by a further receptacle 49 and nose 52 on the middle part 12 and a further nose 53 on the hollow backdrop 11 numerous end positions and intermediate positions for the adjusting element 14 can be formed.

FIG. 7 shows a further alternative embodiment of the device 10 according to FIG. 6 in a mirror-inverted configuration. In this, the slide guide 13 has an additional fourth end position 56 which is arranged, for example, adjacent to the first end position 16. In the case of a vertical alignment of the device 10, a second upper end position for the actuating element 14 is formed by the fourth end position 56. The middle part 12 in this alternative embodiment of the device 10 is in the shape of an entangled double heart, with a fourth intermediate position 57 formed between the two tips of the hearts. The one tip of the crossed heart is arranged laterally offset from the fourth end position 56, so that the actuating element 14 is forcibly guided in a vertically downward positioning movement from the fourth end position 56 along a third oblique edge 58 of the crossed heart in the fourth intermediate position 57. From the fourth intermediate position 57, the actuating element 14 is in turn forcibly directed by a vertically upwardly directed adjusting movement along an oblique flank 74 of a fifth nose 59 into the first end position 16.

Also in this embodiment of the device 10, the number of successive end positions, as well as sawtooth-shaped lugs and intermediate positions can be continued arbitrarily to realize a plurality of side by side and / or arranged at different heights end positions.

All of the aforementioned features are essential to the invention in each case and can be combined with one another as desired.
