Device for rotationally and translationally moving an object
A device for rotationally and translationally moving an object comprising a flat storage area relative to a storage area of a support plate arranged plane-parallel to the storage area, wherein: the object can be rotated relative to the support plate in one of two possible opposing rotational directions and can be displaced in a predefined direction; mutually facing bearing surfaces of the storage areas each have closed peripheral raceway grooves in which rolling elements are guided; the raceway grooves are formed such that, when a force is applied to the object in a direction defined in the plane of the storage area, the object can be moved, in a movement which is at least partially forcibly guided and which is simultaneously rotational and translational, from a starting position into an intermediary position, the object being rotated relative to the support plate in one of two possible opposing rotational directions and being displaced in a predefined direction; and the object, after being moved into the intermediary position, can further be rotated relative to the support plate in the one of two possible opposing rotational directions and can be displaced counter to the predefined direction, and, when rotated by 180°, resumes the base position.
1. A device for the rotational and translational movement of an object comprising a planar bearing region, the device comprising:
a carrier plate having a bearing region,
wherein the planar bearing region of the object is arranged plane-parallel to the bearing region of the carrier plate,
wherein the object is rotatable in relation to the carrier plate in one of two possible opposing rotational directions and is displaceable in a predetermined direction,
wherein bearing surfaces of the respective bearing regions facing toward one another each comprise at least one closed, peripheral running groove, in which roller bodies are guided, wherein the running grooves are formed in such a way that if a force acts on the object in the predetermined direction defined in the plane of the planar bearing region of the object, the object is movable in an at least partially positively-guided, simultaneously rotational and translational movement from a starting position into an intermediate position, during which the object is rotated in relation to the carrier plate in one of the two possible opposing rotational directions and is displaced in the predetermined direction, and wherein the object, after the movement into the intermediate position, is pivotable in relation to the carrier plate further in the one of the two possible opposing rotational directions and is displaceable opposite to the predetermined direction and occupies the base position again upon a pivot of 180°.
2. The device according to claim 1 , wherein two closed, peripheral running grooves are introduced into one of the bearing regions and precisely one closed, peripheral running groove is introduced into the other of the bearing regions.
3. The device according to claim 1 , wherein the roller bodies are formed as balls.
4. The device according to claim 1 , wherein four of the roller bodies are positioned spaced apart from one another and are guided in the running grooves.
5. The device according to claim 1 , wherein the roller bodies are held in a roller body cage.
6. The device according to claim 1 , wherein the bearing regions are formed in one piece with the carrier plate or the object, respectively.
7. The device according to claim 1 , wherein at least one of the bearing regions is formed as a separate element, which is insertable into a correspondingly shaped receptacle in the carrier plate or the object or is attachable by connecting means to the carrier plate or the object, respectively.
8. The device according to claim 1 , wherein a guide is arranged in one of the bearing regions and a guiding and holding element is arranged in or on the other bearing region.
9. The device according to claim 1 , wherein the closed peripheral running grooves are each introduced around the center point of the bearing region of the object and the bearing region of the carrier plate up to a front edge of the carrier plate in the predetermined direction of the translational movement of the object.
10. The device according to claim 1 , wherein the closed peripheral running grooves have multiple catch points for the roller bodies in the base position, which are reached after each rotation of the object by 180°.
11. The device according to claim 1 , wherein the object does not protrude over a rear edge of the carrier plate opposite to the predetermined direction of the translational movement of the object during the entire movement.
12. The device according to claim 1 , wherein the object has at least two bearing regions, and interacts with more than one carrier plate.
13. The device according to claim 1 , wherein the carrier plate is installable recumbent or hanging or standing vertically.
14. The device according to claim 5 wherein the roller bodies are held in the roller body cage captively.
15. The device of claim 1 wherein the running grooves are not parallel to each other.
