Description

Device for moving a cot

Technical area

The invention relates to a device for moving a cot, which is used to enable the child to fall asleep and stay asleep better or to calm the child, for example by rhythmically rocking or moving the cot. State of the art

Devices for moving a cot by electric motor, in particular, in which a cot is set up or positioned with its foot or head part on corresponding supports of the device, are known in many ways from the prior art. From WO 2010/126496 A1, for example, it is known to use variable supports which enable the device to be easily adapted to the respective child's bed or its dimensions. WO 95/23722 discloses the use of rollers and raceways for the rollers for guiding a support element.

By means of the devices described so far, an adaptation of the device to different cot sizes and the possibility of coupling the support surfaces for the head or foot area of a cot with a floor element via roller elements is disclosed. Disclosure of the invention

The device according to the invention for moving a cot with the features of claim 1 has the advantage that it enables variable or particularly simple adaptation to the respective cot size by means of separately designed units for the head or foot area of a cot, with a particularly advantageous one at the same time Kinematics is made possible with regard to the mobility of a cot. Furthermore, a particularly low-noise drive is made possible.

To achieve the above-mentioned advantages, the invention provides that the device for moving the cot has two base elements designed as separate units for placing a head or foot area of a cot, each base element consisting of a floor element for positioning the base element on a surface and a support element arranged movably relative to the base element, in particular a plate-shaped support element, wherein one of the two base elements has a drive which is arranged in the area of a housing of its base element and is connected to the support element by a coupling element, the two support elements in the plane of the support elements are movably arranged, and wherein roller elements are provided to achieve a relative movement between the base elements and the support elements.

Advantageous further developments of the device according to the invention for moving a cot are listed in the subclaims.

With regard to the movement of the cot, two types of movement have proven to be advantageous with a view to the purpose of the device proven. In a first embodiment of the movement of the cot to achieve a (horizontal) pivoting movement, it is provided that the support elements are arranged such that they can pivot about a common axis of rotation arranged perpendicular to the plane of the support elements. The axis of rotation is preferably arranged in the base element which does not have a drive.

In an alternative type of movement of the cot, it is provided that the support elements are arranged so as to be linearly movable in the plane of the support elements.

To achieve positive guidance of the support elements to the floor elements, it is provided that the roller elements, which are preferably pivotable about an axis perpendicular to the plane of the support elements, interact with guide tracks in which the roller elements roll.

A particularly preferred embodiment of the drive, which enables particularly low-noise and jolt-free operation and thus also jolt-free movement of the cot, provides that the drive has an electric motor and a gear connected to the electric motor with a belt drive and a flywheel, and that the coupling element is arranged on the transmission side on a pitch circle diameter around an axis of rotation of an output element of the transmission. Such a design of the drive makes it possible that the electric motor can be operated without reversing the direction of rotation, for example at a constant speed, for example when switching the drive on and off by the flywheel avoiding a sudden start or acceleration and stopping or deceleration of the movement of the cot becomes. In particular, the inertia of rotation of the flywheel in connection with the gear, the The connecting element and the support elements equalize the oscillating movement of the cot, which leads to the jerk-free movement. Furthermore, the use of a belt drive enables particularly good noise decoupling between the individual elements of the transmission, and the coupling element makes it possible to additionally decouple the support surface or the support element from the base element.

Another essential aspect of the invention relates to the manufacturability of the essential elements of the device from a renewable or biodegradable material, which is characterized in particular by being free from harmful substances. Against this background, it is preferably provided that the housing of the floor elements and the support elements each consist at least essentially of a wood material.

A further improved noise insulation is achieved if the drive is connected to the housing of its base element via damping elements.

A likewise improved noise insulation is achieved if additional noise insulation elements are arranged in the housing of the floor element having the drive. These additional noise insulation elements can serve, for example, to subdivide the interior of the housing into smaller sub-areas in order to make the propagation of sound more difficult or to avoid resonance effects. In addition to the use of soundproofing elements made of the same material as the housing, it is also conceivable to use, for example, foams or similar sound-absorbing materials or structures. In order to avoid unintentional movement of the cot and mechanical loads on the drive of the cot when the drive is not activated, a further preferred structural embodiment of the device provides that the support element can be fixed to its associated floor element by means of locking means. A relative movement between the support element and the base element in relation to the axis of rotation is thus avoided. Furthermore, the initial alignment of the support element with respect to the floor element can take place through the locking means. This is particularly advantageous if guide tracks that interact with the roller elements are to be dispensed with.

The use of two separate base units enables the device to be adapted to different cot sizes in a particularly simple manner. For this purpose, it is only necessary to bring the respective head or foot area of the child's bed into alignment or overlap with the support surface of the respective base unit. However, since children's beds typically have standardized sizes, to simplify the precise positioning of the two base elements with respect to one another, the base elements can be rigidly connected to one another by means of at least one connecting element in order to set a distance and the relative position between the two base elements.

In a further development of this proposal, it is provided that the at least one connecting element can be coupled to the bottom element of the base element or to another connecting element by means of a form-fitting connection. The use of a form-fit connection has the particular advantage that the assemblies of the device can be assembled without tools. It can also be particularly advantageous to couple the two support elements of the base elements to one another with the at least one connecting element, since then the forces for moving the cot are transmitted directly via the support elements and not via the cot.

Another important aspect of the invention relates to the electrical control or different operating modes of the device or the drive. For this purpose, a further embodiment of the invention provides that the drive can be controlled manually and / or wirelessly and a control and radio module enables different functionalities with regard to the speed of the drive, the duration and / or the start of the drive and, if necessary, temporal speed curves. Furthermore, this possibility also includes a time limitation of the drive or the movement of the cot, such that, for example, after a certain period of time, for example after 10 minutes, a constant movement of the cot, for example, is continuously reduced to a standstill.

It can also be provided that lighting devices or monitoring devices are arranged and / or can be mounted on the base elements. Such lighting devices are provided, for example, in the area of the floor element in the form of dimmable or energy-saving lighting means that illuminate the floor area in order to avoid influencing the child's sleep. The floor lighting acts as a night light on the one hand, and on the other hand makes it particularly easy to find the bed in the room even when the lights are switched off. Monitoring devices are understood to mean, for example, microphones, motion detectors, video cameras or the like, which can optionally be arranged on corresponding tripods or the like, on carrier devices that can be mounted on the base elements. Further advantages, features and details of the invention emerge from the following description of preferred embodiments of the invention and with reference to the drawings.

Embodiments of the invention

The same elements or elements with the same function are provided with the same reference numbers in the figures.

In Fig. 1, the essential components of a device 10 for moving a cot 1 are shown. The device 10 comprises two base elements 12, 14 for setting up the cot 1 on the device 10 in the area of the head part 2 or foot part 3 of the cot 1. The two base elements 12, 14 are preferably rigidly connected to one another by means of at least one connecting element 16, 17. Each Base element 12, 14 comprises a floor element 19, 20 for positioning the respective base element 12, 14 on a substrate, typically a floor. Furthermore, each base element 12, 14 comprises an in particular plate-shaped support element 21, 22, which rests on the respective floor element 19, 20, and on whose side facing away from the floor element 19, 20 the head part 2 or the foot part 3 of the cot 1 can be positioned.

In FIG. 2, the cot 1 and the device 10 are shown in a simplified representation during the operation of the device 10. In particular, it can be seen that the two support elements 21, 22 are movable about an axis of rotation 24 running vertically to the plane of the support elements 21, 22 in the direction of the double arrow 25.

3 and 6 it can be seen that the two connecting elements 16, 17 are each formed from elongated or flat elements (preferably made of wood), with on the one hand between the two connecting elements 16, 17 and on the other hand between the connecting element 16, 17 and the floor element 19, 20 facing it each have a form-fit connection 27, 28. The form-fit connection 27, 28 enables simple assembly of the device 10 without additional tools or aids. Furthermore, particularly due to the divisibility or the possibility of providing a plurality of connecting elements 16, 17, a particularly compact structure or a particularly compact stowage of the individual parts of the device 10 is possible.

In addition, it is mentioned that it is also conceivable and possibly advantageous for stepless adjustment of the distance between the two floor elements 19, 20 to use a single, telescopic connecting element instead of several connecting elements 16, 17, in which case however, a form-fit connection of such a connecting element to the base elements 19, 20 is still provided (not shown). It can also be provided that the at least one connecting element 16, 17 does not connect the two floor elements 19, 20 to one another, but rather the two support elements 21, 22.

In Fig. 3 it can also be seen that the two bottom elements 19, 20 each have housings 30, 31, which are designed in the manner of a box of flat side walls, preferably consisting of a wood material with a thickness of about 10 mm, for example. In the bottom element 19 of the base element 12, which is assigned, for example, to the head part 2 of the cot 1, a drive 40 is also arranged.

In order to enable a relative movement of the support elements 21, 22 on the respective floor element 19, 20, each

Floor element 19, 20, for example, four roller elements 32, 33 are provided, which are arranged on corresponding pitch circle diameters 34, 35 with a view of the axis of rotation 24 and / or are pivotably mounted about an axis running perpendicular to the plane of the support elements 21, 22. The roller elements 32, 33 project beyond the base elements 19, 20 or their cover element 36, which can only be seen in FIG. 8 using the example of the one base element 19, in such a way that circular segment-like guide tracks 37, 38 (FIG. 4) arranged in the support elements 21, 22 are arranged in operative connection or in engagement with the roller elements 32, 33.

In addition, it is mentioned that it is also possible to dispense with the guide tracks 37, 38 and to set the alignment of the support elements 21, 22 with respect to the floor elements 19, 20 manually. During operation of the device 10, the positioning of the support elements 21, 22 is carried out the overlying cot 1 and the frictional connection between the head part 2 and the foot part 3 and the support elements 21, 22 causes.

In FIG. 6 it can be seen that the housing 30 of the base element 19, which is assigned to the base element 12, has elevations 41 adapted in the cross section of the guide tracks 37, which reduce the gap between the support element 21 and the base element 19, in particular to prevent the penetration of dirt or To minimize dust and the risk of trapping fingers.

As shown in FIGS. 3, 7, 9 and 10, the drive 40 comprises an electric motor 42, which is preferably driven in only one direction of rotation. The electric motor 42 or the drive 40 is arranged via a motor mount 43 (FIG. 12) and damping elements 44 in the interior of the base element 19 or the housing 30 and is connected to the housing 30. The electric motor 42 acts via a gear 45 on a coupling element in the form of a coupling rod 47, which is connected to the underside of the support element 21 at a connection point 48. The coupling rod 47 preferably has a ball element at its respective end area, which can be easily detached or assembled manually.

The transmission 45 comprises a belt drive 50 and a flywheel 52. The flywheel 52 acts on an output element in the form of an output disk 54, which is connected to the coupling rod 47 on a pitch circle diameter 53.

To avoid the penetration of dust or dirt into the housing 30 of the base element 19 and to minimize noise, it is also provided that noise insulation elements 55 are arranged in the interior of the housing 30, and that between the A sealing element (not shown) for bridging the gap can be arranged on the upper side of the base element 19 and the underside of the support element 21.

In FIG. 6 it can be seen that two loudspeakers 57, 58 are arranged in the housing 30 on the housing side facing the one connecting element 16. Illuminants, preferably in the form of LEDs, can also be arranged in the area of openings 59, which are used in particular to illuminate the floor area below the cot 1. In FIG. 11 it can be seen that a carrier element 60, which is designed in the form of a rod, can also be mounted, for example, on the base element 19. The carrier element 16 is used, for example, to attach or arrange a surveillance camera 5 or the like. Microphones or the like can also be provided in order to trigger a corresponding signal when the child wakes up or makes a noise.

The drive 40 of the electric motor 42 is implemented via a control and radio module 65, which enables either manual operation or wireless operation, for example via a corresponding application on a mobile terminal. In this case, the control and radio module 65 includes, for example, programs for speed regulation or temporal progressions of speeds as well as shutdown functions or the like.

In order to avoid unintentional movement of the cot 1, a locking bolt 66 is provided as a locking means in the area of the base element 19, for example, which interacts with an opposite opening 67 in the associated support element 21 (FIG. 5). The, for example, spring-loaded locking bolt 66 interacts with a switch 68 in such a way that when the support element 21 is locked, the drive 40 of the electric motor 42 is deactivated. Finally, FIG. 13 shows that the device 10 can also be designed to achieve a linear movement of the cot 1 in the plane of the cot by appropriate design of the drive 40 (and possibly the roller elements 32, 33 and the guide tracks 37, 38) Carry out support elements 21, 22 in the direction of double arrow 69. The movement is preferably carried out in the longitudinal direction of the cot 1, since in this way no torque arises between the driven and non-driven support elements 21, 22.

The device 10 described so far can be modified or modified in many ways without deviating from the inventive concept.
