Description

State of the art

[0001] Various embodiments of a device for moving a movable furniture part relative to a furniture body are known from the prior art. In these embodiments, the movable furniture part can be moved by means of guides in an opening direction and in a closing direction opposite to the opening direction. The devices include a power storage device. Under the action of the power storage device, it is possible to eject the movable furniture part in the opening direction via an ejector, i.e., to move it into an open position.

[0002] In these known devices, charging of the energy storage unit can occur both when the movable part of the furniture is fully opened and when it is closed with respect to the furniture body. Purpose and advantages of the invention

[0003] The invention is based on the objective of improving, and in particular simplifying, a device for moving a movable part of a piece of furniture or a device for moving a sliding element of a household appliance.

[0004] This problem is solved by the independent claims.

[0005] The dependent claims specify advantageous and appropriate embodiments of the invention.

[0006] The invention relates to a device for moving a movable furniture part in an opening direction relative to a furniture body or for moving a sliding element in an opening direction relative to a household appliance, wherein the movable furniture part or the movable sliding element can be moved via guide means of the furniture or the household appliance in the opening direction and in a closing direction opposite to the opening direction, wherein the device has a force storage device, an ejector and a guide track for guiding the ejector, so that with the device mounted on the furniture or the household appliance, the movable furniture part or the sliding element can be moved from a closed position into the opening direction under the action of the force storage device during an opening process.by the energy storage device driving the ejector in an opening direction and by the fact that an opening movement of the ejector can be transferred to the movable furniture part or the sliding element, wherein a charging process of the energy storage device takes place when the ejector moves in a closing direction.

[0007] The movable furniture component is designed, in particular, as a drawer. The device is advantageously configured as a furniture fitting, e.g., a drawer moving device, and / or as a household appliance fitting, e.g., a sliding element moving device. The household appliance is, for example, designed as an oven or a dishwasher. The sliding element of the household appliance is preferably configured as a baking tray or a baking rack.

[0008] The movable furniture part or drawer element moves during opening or closing, for example, in a purely or exclusively linear motion. The guide elements include, for example, conventional drawer slides. These guide elements may be conventional extension slides, such as partial or full extension slides.

[0009] The device is advantageously designed to be arranged on the underside of a drawer bottom or on the guide elements of the furniture. Preferably, the ejector includes a contact element for direct or immediate contact with a driver of the furniture body or a driver of the movable furniture part.

[0010] It is conceivable that the device could be arranged on the furniture or household appliance in such a way that the opening movement of the ejector is synchronized with the opening movement of the movable furniture part or the sliding element. However, the reverse is also conceivable, where the opening movement of the ejector is opposed to the opening movement of the movable furniture part or the sliding element. The same applies to the closing movements.

[0011] The key aspect of the invention lies in the fact that the guide track is loop-shaped, so that the ejector is guided by the guide track in a loop. This allows the device to be implemented with relatively few components and has a comparatively simple design.

[0012] The ejector's base body is, for example, disc-shaped or disk-like. For instance, the base body is hook-shaped. Preferably, the ejector comprises one or more guide elements. For example, a guide element is movably guided by a guide track. Preferably, a guide element is movably guided on the guide track. The guide element is, for example, pin-, nose-, and / or bolt-shaped. The guide element advantageously projects from the ejector's base body, particularly from an underside of the base body. The guide track is, for example, designed as a guide contour.

[0013] The guide track is, for example, ring-shaped or loop-shaped. Advantageously, the ejector is guided by the guide track in a kind of endless loop or continuous movement. A movement path of the ejector, in particular a movement path of the ejector's guide element, is, for example, ring-shaped or loop-shaped.

[0014] As an alternative or supplementary solution to the invention, a device for moving a movable furniture part in an opening direction and a closing direction with respect to a furniture body or for moving a sliding element in an opening direction and a closing direction with respect to a household appliance is proposed, wherein the movable furniture part or the sliding element can be moved in the opening direction and in the closing direction opposite to the opening direction via guide means of the furniture or the household appliance, wherein the device has a, in particular, a single energy storage device, a, in particular, a single ejector and a guide track for guiding the ejector.The device mounted on the furniture or household appliance allows the movable furniture part or drawer element to be moved from a closed position into the opening direction by the force storage device during an opening process, and vice versa, by the force storage device driving the ejector in an opening or closing direction, thus transferring the opening or closing movement of the ejector to the movable furniture part or drawer element. This makes the device comparatively simple in design for moving a movable furniture part in both the opening and closing directions relative to a cabinet.

[0015] Advantageously, the device, particularly when mounted on the furniture, is designed to move the movable furniture part or the sliding element towards the body of the furniture or the household appliance in the closing direction when the movable furniture part or the sliding element is moved in the closing direction, wherein the ejector is designed to couple with the movable furniture part or the sliding element during the closing movement.

[0016] For example, the ejector is designed to couple with a drive element of the movable furniture part or with a drive element of the sliding element. For instance, the ejector includes a drive element, such as a latch component. Advantageously, the device also functions as an automatic retraction mechanism. For example, the device can be configured as an ejection and / or retraction device.

[0017] Advantageously, the energy storage device is charged when the ejector moves in the closing direction. However, it is also conceivable that the device is configured so that the energy storage device is charged when the ejector moves in the opening direction. Therefore, the device is advantageously designed or can be arranged on the furniture or household appliance in such a way that the energy storage device can be charged during either a closing or an opening movement of the movable furniture part or sliding element.

[0018] The energy storage device is, for example, present as an energy storage package. This package comprises, for example, several spring elements, particularly those acting in the same way. One component of the energy storage device, e.g., a spring element or a connecting element, moves during the opening or closing movement of the ejector, for example, along a path that is, in particular, exclusively linear.

[0019] It is further proposed that the guide track of the device be designed in a loop shape, so that the ejector is guided by the guide track in a loop. It also proves advantageous that a charging process of the energy storage device occurs when the ejector moves in the closing direction.

[0020] Furthermore, it proves advantageous that the ejector is pivotally coupled to the energy storage device. Advantageously, the ejector is directly and / or immediately connected to the energy storage device. For example, the ejector is pivotally mounted on the energy storage device by means of a hinge. For example, the ejector includes a slot or, for instance, an oval recess into which the connection element of the energy storage device engages, so that the ejector is pivotally coupled to the energy storage device.

[0021] In an advantageous embodiment of the device, the guide track is designed such that the ejector initially performs a linear movement during the opening process and, in particular, additionally performs a pivoting movement at the end of the opening movement. The linear opening movement advantageously comprises exclusively a movement component of the ejector in the opening direction of the ejector and / or in the ejection direction of the movable furniture part.

[0022] Furthermore, it is proposed that the guide track be designed such that the ejector initially performs a linear movement during the closing process and, at the end of the closing movement, additionally or, in particular, exclusively, performs a pivoting movement. Advantageously, the linear closing movement comprises only a movement component in the closing direction of the ejector and / or in the closing direction of the movable furniture part. Advantageously, the ejector is guided in a closed loop for movement.

[0023] Preferably, the energy storage device is partially discharged during the closing process, particularly by the pivoting movement of the ejector. Specifically, the energy storage device is partially discharged during the pivoting movement of the ejector's closing process. For example, the energy storage device is charged during the closing process of the ejector, either during and / or by the ejector's linear movement. For example, the ejector is moved in a pivoting movement by a force from the energy storage device at the end of the closing process, with the ejector being guided in this pivoting movement by the guide track.

[0024] For example, during the pivoting motion of the closing process, the ejector experiences a force charge from the energy storage device that is between 2% and 20%, between 2% and 18%, between 5% and 18%, or between 2% and 10% of its maximum achievable charging capacity in the device's installed state. For example, the energy storage device is fully charged at the end of the ejector's linear closing motion and discharges during the ejector's pivoting motion by exerting a force on the ejector. For example, the energy storage device has its maximum achievable charging capacity at the end of the ejector's linear closing motion.

[0025] It is also advantageous that the ejector guide device has an additional guide track. This improves the ejector's movement, for example, preventing it from tilting. Advantageously, this makes the device comparatively more stable. The additional guide track is also advantageously designed in a loop-like shape.

[0026] It is further proposed that one guide track and / or the other guide track be designed as a loop.

[0027] Advantageously, one, two, or more guideways are configured as a closed loop. For example, the guideway may be a single guide contour. It is also conceivable that the guideway is annular or circular, e.g., a circular path. Advantageously, the ejector is guided by one, both, or more guideways.

[0028] In an advantageous modification of the invention, the ejector comprises a first and a second guide element, wherein the first guide element is movably guided by one guide track, wherein the second guide element is movably guided by the further guide track, wherein in an opening and / or closing movement of the ejector the guide elements are guided in opposite directions in the guide tracks.

[0029] Viewed from one perspective, the first guide element is, for example, movably guided in a clockwise direction, and the second guide element is, for example, movably guided counterclockwise, or vice versa. Advantageously, in the opening and / or closing movement of the ejector, the first and second guide elements move in opposite directions. For example, one and the other guide track of the device are arranged one behind the other or side by side in the opening and / or closing direction of the ejector and / or the movable furniture part. Guide elements of the ejector are advantageously spaced apart from each other on the ejector, particularly on the base of the ejector.

[0030] It is also proposed that a guide track has a locking element, and that the locking element on the guide track is designed in such a way that a direction of movement of the guide element in the guide track is specified.

[0031] The locking element is, for example, provided as an incline and / or a ramp on the guide track, and a guide element is guided along the incline and / or along the guide track during the opening and / or closing movement of the ejector such that the ejector is tilted within the movement range of the incline. For example, the locking element, in particular the incline, includes a stop surface so that the guide element of the ejector, guided by the guide track, can abut the stop surface, thereby defining a single direction of travel and / or a single direction of movement of the guide element through the loop-shaped guide track. The locking element is advantageously located at one end of the opening and / or closing movement of the ejector on the guide track. It is also conceivable that the locking element is elastically designed. For example, the locking element is designed as a spring element.Advantageously, each guideway includes a locking device.

[0032] Furthermore, it proves advantageous that the device has a guide element, wherein the guide element comprises a linearly designed guide contour, wherein the ejector is guided in a linearly movable manner by the guide contour of the guide element.

[0033] Advantageously, the ejector comprises a third guide element, wherein the third guide element is movably guided within the guide contour of the guide element. Preferably, the ejector is rotatably mounted relative to the guide element. In particular, the ejector has a center of rotation located on the third guide element or on the guide element. For example, the ejector is pivotally and / or rotatably mounted on the device about a rotational axis of the third guide element. The rotational axis of the third guide element is, for example, provided as a center of rotation. Preferably, a rotational axis of the third guide element forms a center of rotation about which the first and / or the second guide element are rotatably mounted.

[0034] It is also preferred that the device has locking means, wherein the locking means are designed and arranged on the device such that the locking means catch the ejector at the end of the closing movement of the ejector, so that the energy storage device is held in a charged state.

[0035] Preferably, the ejector comprises a locking element configured to interact with, and in particular to couple with, the locking means. For example, a locking element of the locking means is configured such that, at the end of the ejector's closing movement, the locking element holds the ejector in a detent position, e.g., by engaging behind and / or around the locking element. In the detent position of the ejector, the energy storage device is in a partially charged or partially discharged state. For example, in the detent position, the energy storage device is charged to more than 50%, more than 70%, more than 80%, or more than 90% of its maximum achievable charging capacity in the configured state.

[0036] Advantageously, the ejector is decoupled from the movable furniture part at the end of its closing movement, in particular by a drive element of the movable furniture part. Advantageously, the device is designed such that contact between the movable furniture part and the ejector in the detent position or the detent position of the ejector is prevented.

[0037] It is also advantageous for the locking means to include a rocker arm. For example, the locking element is designed as a rocker arm. This allows the ejector to be released from its detent position with a comparatively short or small rotational movement. Advantageously, a movement component of the ejector, perpendicular to a rotational axis of the rocker arm, is always present during the closing and / or opening movement of the ejector. For example, a pivoting movement component of the ejector is aligned parallel to the rotational axis of the rocker arm during the closing and / or opening movement. Preferably, a rotational axis of the ejector is aligned perpendicular to a rotational axis of the locking means, in particular to the rotational axis of the rocker arm.

[0038] Furthermore, it is advantageous for the device to have an adjustment unit, the adjustment unit being connected to the energy storage device in order to set a, in particular, maximum spring force of the energy storage device, wherein the adjustment unit is designed in a scissor-like manner. The adjustment unit advantageously comprises two lever arms, each of which is pivotally, and in particular rotatably, arranged at one end on the device, especially on a housing of the device. Advantageously, one lever arm is connected at a second end to the energy storage device, and the other lever arm comprises at a second end an operating element for adjusting the adjustment unit and thus a spring force of the energy storage device by a user. The two lever arms are also pivotally coupled to each other, for example, such that the levers can perform a scissor-like movement.

[0039] A furniture or household appliance with a device according to one of the aforementioned variants proves to be an advantageous modification of the invention. Description of an exemplary embodiment

[0040] Further features and advantages of the invention are explained in more detail with reference to an exemplary embodiment shown schematically in the figures.

[0041] Specifically, we show: Fig. 1 a piece of furniture according to the invention shown in perspective from an oblique angle above with a drawer in the fully open state on a furniture body, Fig. 2 a device according to the invention with an ejector and a power storage device in a perspective view from an oblique side view from above and Fig. 3, Fig. 4, Fig. 5 to Fig. 6 the device according to Fig. 2 from a top view, with the ejector and the power storage unit taking on different positions in the figures.

[0042] A piece of furniture 1 according to the invention, comprising a box-shaped furniture body 2 and a drawer 4 movably guided by means of guide means 3, is in Fig. Figure 1 shows the drawer 4 comprising a drawer base 5, a drawer front 6, two opposing side walls 7, 8, and a drawer back wall 11. Two synchronously acting guide elements 3 are provided between each side wall 7, 8 of the drawer 4 and a corresponding cabinet side wall 9, 10 for guiding the drawer 4. For example, a device 12 according to the invention (shown in dashed lines) is arranged on the underside of the drawer base 5 for moving or ejecting the movable furniture part designed as a drawer 4 in the opening direction M1 of the furniture part. A closing direction M2 of the furniture part is configured opposite to the opening direction M1.

[0043] In Fig. Figure 2 shows the device 12. The device 12 comprises, for example, a base body 13, an ejector 14, a power storage device 15, locking means 16, and an adjustment unit 17. A first guide track 18, a second guide track 19, and / or a guide contour 20, for example, as a recess, are formed on the base body 13. In the arranged state of the ejector 14 on the base body 13, the guide tracks 18, 19, and / or the guide contour 20 define a movement or a range of movement of the ejector 14.

[0044] The energy storage device 15 comprises, for example, a spring assembly 21. The energy storage device 15 is coupled at a first end 22 to a first lever arm 23 of the adjusting unit 17 and at a second end 24 to the ejector 14. The energy storage device 15 is arranged at its first and / or second end 22, 24, for example, on the base body 13 such that the base body 13 is designed, for example, such that the energy storage device 15 is movable at its first and / or second end 22, 24, in particular exclusively in a linear manner.

[0045] The adjusting unit 17 comprises a first lever arm 23 and a second lever arm 25. The first lever arm 23 is coupled at a first end to the first end 22 of the energy storage device 15, in particular by pivoting and / or rotating movement. At a second end of the lever arm 23, which is spaced apart from and opposite the first end of the lever arm 23, the lever arm 23 is mounted on the base body 13 of the device 12 via a joint 26, in particular by rotating movement. The second lever arm 25 has an operating element 32, e.g., in the form of a handle, at a first end 27. At a second end of the second lever arm 25, the second lever arm 25 is mounted on the base body 13 of the device 12 via a joint 28, in particular by rotating movement. The two lever arms 23, 25 of the adjusting unit 17 are advantageously arranged on the base body 13 such that the two lever arms 23, 25 cross, overlap and / or superimpose.In the area where the two lever arms 23 and 25 intersect, they are pivotally coupled to one another. For example, the first lever arm 23 includes a movement contour 29 through which a control element 30 of the second lever arm 25 is guided. The movement contour 29 is, for example, a recess on the lever arm 23. The control element 30 is, for example, a pin projecting from a base surface 31 of the second lever arm 25. This, and / or the mounting of the lever arms 23 and 25 on the base body 13, enables a scissor-like movement of the two lever arms 23 and 25. The movement contour 29 is advantageously designed such that a spring force of the energy storage device 15 can be adjusted in discrete steps, e.g., in stages, for example, in two, three, or more steps.For example, the movement contour 29 comprises two, three, or more holding areas at which the control element 30 engages with the movement contour 29, particularly due to the advantageous arrangement on the base body 13 and the energy storage device 15. In the arranged state on the device 12, advantageously only the first end 27 of the second lever arm 25, e.g., the handle, is visible and operable for a user of the device 12.

[0046] The ejector 14, in particular a base body 39 of the ejector 14, is advantageously designed as a flat, disc-like component. A guide element 33 is provided on the underside of the base body 39 of the ejector 14. In particular, two or three guide elements 33, 34, 35 are provided on the ejector 14. Advantageously, one guide element 33 couples with the guide track 18, one guide element 34 with the guide track 19, and one guide element 35 with the guide contour 20. The guide element 33, for example, projects from the underside of the ejector 14 and engages in the guide track 18. For example, the guide element 33 is designed as a pin. The ejector 14 also includes a contact element 36. The contact element 36 has a contact surface 37 for contacting a driver 38, e.g., a guide rail of the guide means. The attachment element 36 can be formed integrally with the base body 39 of the ejector 14.Furthermore, the ejector 14, in particular on the base body 39 of the ejector 14, comprises a locking element 46. The locking element is advantageously designed to couple with a rocker 47 of the locking means 16 in a detent position of the device 12 (see . Fig. 3).

[0047] Contours, in particular outer contours of the guideways 18, 19, are, for example, formed at least approximately mirror-symmetrically. The guideways 18, 19 are, for example, formed in the form of, e.g., ring- or loop-shaped guide slots on the base body 39 of the ejector 14. The guideways 18, 19 comprise, for example, two straight, in particular linear, guide slot sections 40, 41, wherein the straight guide slot sections 40, 41 are spaced apart from each other and are located opposite one another. The ends of the straight guide slot sections 40, 41 are, for example, connected to each other via two further, curved guide slot sections 42, 43. (For the sake of clarity, only the guide slot sections of the guideway 18 are provided with reference numerals in the drawings.)Advantageously, one end of a straight guide slot section 40 of a guide track 18 is offset from the other straight guide slot section 41 of the same guide track 18 in an opening or closing direction M1, M2 on the base body 39 of the ejector 14. The straight guide slot sections 40, 41 of the guide tracks 18, 19 are advantageously parallel to an opening or closing direction M1, M2. Advantageously, the two straight guide slot sections 40, 41 of a guide track 18 are of different lengths.

[0048] The guide track 18, 19 also advantageously includes a locking element 44. The locking element 44 is, for example, designed as a ramp on the guide track 18, 19, so that the guide element 33 experiences a height difference relative to a base surface 45 of the base body 13 when moving along the guide track 18 over the ramp.

[0049] The guide contour 20 is advantageously provided as a straight, in particular linear, guide slot on the base body 13 of the ejector 14. For example, the guide contour 20 is formed parallel to an opening or closing direction M1, M2. The length of the guide contour 20 advantageously corresponds to the length of a straight guide slot section 40, 41 of the guide track 18, 19, in particular the length of the longest straight guide slot section 41 of the guide track 18, 19. It is also conceivable that the guide contour 20 has a length greater than the length of the longest straight guide slot section 41 of the guide track 18, 19.

[0050] In Fig. Figure 3 shows the device 12 in a latched position. The ejector 14 is located in Fig. 3 in the detent position. The locking element 46 of the ejector 14 is locked in the detent position with a locking element 48 of the rocker 47. The energy storage device 15 is advantageously in a partially discharged state in the detent position.

[0051] The following will proceed starting from the detent position of device 12 accordingly Fig. 3 based on the Fig. 3, Fig. 4, Fig. 5 to Fig. 6. A sequence of movements of the device 12 and in particular of the ejector 14 and the energy storage device 15 during an opening and closing process of the device 12 is explained: The release of the locking connection between the locking element 46 and the locking mechanism 48 is advantageously achieved by a user moving or pushing the drawer 4 from the outside towards the furniture body 2, and thus in the closing direction M2. This causes the drawer 4's follower 38 to push a release 49 of the locking means 16 in the closing direction M2. The release 49 is in turn connected to the rocker 47 such that the movement of the release 49 in the closing direction M2 causes the rocker 47 to rotate about its axis of rotation W. This rotation of the rocker 47 about the axis of rotation W moves the locking mechanism 48 of the rocker 47 away from the base 45 of the base body 13 of the device, thus releasing the coupling between the locking mechanism 48 and the locking element 46 of the ejector 14.

[0052] By releasing the coupling between locking element 48 and locking element 46, a force is released from the energy storage device 15, causing the energy storage device 15 to move the ejector 14 in the opening direction M1. In doing so, the ejector 14, with the contact 37 of the contact element 36, engages the driver 38 of the drawer 4 and thus the drawer 4 itself in the opening direction M1, thereby moving or ejecting the drawer 4 in the opening direction M1. In the first part of the opening movement, the ejector 14 is disengaged from the detent position ( Fig. 3) to the position in Fig. 4 guided by the straight guide slot sections 40 of the guide tracks 18, 19 and the guide contour 20. In a second subsection of the opening movement of the ejector 14 from the position in Fig. 4 to the position in Fig. 5. The ejector 14 is guided by the curved guide slot sections 43 of the guide tracks 18, 19 and by the guide contour 20. In the second part of the opening movement, the ejector 14, due to its guidance in the guide tracks 18, 19 and the guide contour 20, is additionally guided, or in particular forced, into a rotational movement about an axis of rotation A, in addition to its movement in the opening direction M1. During the rotational movement of the ejector 14 during the opening movement, the two guide elements 33 and 34 move in the same direction of rotation, in particular counterclockwise, when viewed from above the base surface 45 of the device 12. During the rotational movement of the ejector 14 during the opening movement, the guide element 33 moves along the guide track 18, for example, in the opposite direction to the movement of the guide element 34 along the guide track 19.The guide element 35, and thus also the pivot point of the ejector 14, ideally continue to move parallel to the opening direction M1 during the second part of the opening movement of the ejector 14. Advantageously, the trigger 49 is spring-loaded, so that the trigger 49 returns to its initial position during the opening movement of the ejector 14.

[0053] In the first part of the opening movement of the ejector 14, the energy storage device 15 relaxes, for example, by about 80% of its maximum force achievable at the device 12. In the second part of the opening movement of the ejector 14, the energy storage device 15 relaxes, for example, by about 15% of its maximum force achievable at the device 12. At the end of the opening movement of the ejector 14, the ejector 14 is in a position corresponding to Fig. For example, the power storage unit 15 is pre-tensioned.

[0054] At the end of the second part of the opening movement of the ejector 14, and thus in a region at one end of the guide slot section 34, the locking element 44 is formed. The locking element 44 is positioned such that the guide element 33 or 34 passes over or is guided through the locking element 44 at the end of the second part of the opening movement of the ejector 14. In one end position of the opening movement of the ejector 14, the driver 38 of the drawer 4 has left the contact element 36 in the opening direction M1, and the drawer 4 has moved into an open position. At the end position (see Fig. 5) Movement of the ejector 14 along the guide slot section 43 is blocked by the locking element 44. In particular, in the end position, a clockwise rotational movement of the ejector 14 is blocked when viewed from above the base surface 45 of the device 12.

[0055] During a closing movement of drawer 4, e.g., caused by a user from the outside who moves the drawer in closing direction M2 towards the furniture body 2, the follower 38 of drawer 4 presses the contact element 36 of the ejector 14 and thus the ejector 14 in closing direction M2. In the first part of the closing movement, the ejector 14 is moved from its end position accordingly. Fig. 5 into an intermediate position accordingly Fig. 6 moves and the energy storage device 15 is charged during this movement along the first section. In the intermediate position accordingly Fig. 6. The energy storage device 15 has its maximum achievable energy charge on the device.
