Description

Opening and closing devices for movable furniture parts

technical field

The invention relates to an opening and closing device for a movable furniture part, in particular a drawer, with a retracting device and an ejecting device, and an ejecting device, wherein the ejecting device With a bracket pretensioned by a force accumulator, which can be unlocked in the end position of the guide path and can be coupled to the carriage.

Background technique

An opening device for movable furniture is known, which moves a movable furniture part towards the opening direction by means of an ejection mechanism (EP766939). Such an opening device holds the movable furniture part in a predetermined closed position so that it is unlocked and the movable furniture part is ejected by pulling or pressing in the movable furniture part. With such opening devices, there is the disadvantage that the opening device must be mounted very precisely in order to predefine the closed position of the movable furniture in order to achieve an excellent panel appearance.

Contents of the invention

It is therefore an object of the present invention to provide an opening and closing device for movable furniture parts which is easy to install and which, moreover, ensures comfortable handling.

This object is achieved with an opening and closing device with the features of claim 1 and with an ejection device with the features of claim 18 .

According to the invention, the pop-up stop is coupled with the pop-up drive such that both pulling and pushing forces can be transmitted. Thus, catches can be provided on the carriage so that the carriage can be locked during the opening and closing process. Functional reliability is thus increased due to the precise guidance of the carriage and gripper.

According to a preferred embodiment, two stoppers spaced apart from each other are provided on the carriage, wherein the first stopper can be coupled with the bracket in the ejecting direction, and the second stopper can be coupled with the bracket in the retracting direction. It can thus be ensured that the ejection device can be tensioned by the first stop before the closed position is reached. The stop acting in the retracting direction is designed to be elastic and can be moved over the bracket in the opening direction to snap into place. The stop acting in the closing direction is disengaged from the support when the support is pivoted and is in a tensioned and locked position, for example when moving along a guide path with an angled end.

According to a further embodiment, magnets are provided on the pop-out stop, which can be coupled to the metallic stationary drive. If the pop-up stop is capable of transmitting not only pushing but also pulling forces, in particular coupled via the pop-up stop to a stationary drive, the carriage will be pulled along the guide path. This enables the first stop to be decoupled from the carrier in a simple manner and the second stop to engage the carrier on the carriage.

Instead of magnets, a movable latch is supported on the carriage, which is coupled to the drive during the closing movement and decoupled from the drive from a specific position during the opening movement.

According to another embodiment, a pivotable lever is provided which forms a stop for the carriage and with which lever the carriage can be unlocked from the end position for the ejection means to act. The closed position can thus be preset with the pivotable lever, which forms a stop. The retraction mechanism ensures that the closed position is reached with the carriage resting on the rod without requiring the user to move the movable furniture part precisely into the closed position.

Preferably, the carriage is pulled in the closing direction by the retracting means in the closed position and the retaining force of the bracket is greater than the triggering force exerted by the lever in the locked position against which the carriage rests. Thus, the movable furniture part is locked or snapped in the closed position, so the system is stable if only the retraction means act in the closed position and the carriage is pulled in the closing direction.

Preferably, the force accumulator of the ejection device is tensioned when the movable furniture part is closed, wherein the deformation of the tension accumulator is arranged at a distance of, for example, between 2 and 5 cm from the closed position. This operation is particularly simplified since the user no longer needs to lock the furniture part precisely to the furniture body. The retraction device acts at the end of the strained deformation of the force accumulator of the ejection device during the closing process. The offset between the tensioned and the actual closed position of the ejection device can thus be automatically covered by the retraction device. In order to avoid hard block noise, the retracting device can also be designed as a buffer.

Preferably, the ejection means has two guide paths, one to guide the bracket, and has a form that is generally curved as a crutch (ie a straight guide path with a bent angled portion). The other guide path serves to guide the carriage or carriage carriage and preferably has no angled sections. Three guide paths can also be provided on the housing.

The retracting device and the ejecting device are preferably mounted on the movable furniture part and/or the furniture body at a distance from each other. The construction space can thus be used efficiently. For example, the housing of the ejection device may be mounted on the bottom side of the drawer, while the retraction device may be housed in the side frame of the drawer.

Detailed ways

A piece of furniture 1 comprises a furniture body 2 (schematically illustrated) on which a pusher element in the form of a drawer 3 is mounted, which is movable. To this end, pull-out guides 5 are provided on opposite sides of the drawer 3 , which are fastened to the furniture body 2 via angles 9 . The drawer 3 with the front panel 4 can be ejected in the opening direction by means of the ejection device 6 , wherein the ejection device 6 is supported on an angled drive 7 mounted on the furniture body 2 . The angle drive 7 is fastened to a fixed furniture part, such as a body wall, a body angle of a pull-out guide, or a guide rail of a pull-out guide. For example, the horn drive 7 can likewise be integrally formed with the main body horn of the pull-out guide or with the guide rail of the pull-out guide. The opening and closing device according to the invention can be used, for example, with drawers, but it can also be used for other movable furniture parts, such as sliding doors, push elements and flaps.

As shown in FIG. 2 , the ejector 6 is mounted on the bottom side of the drawer 3 , while the pull-out guide 5 is housed in the side frame 8 of the drawer 3 . On the extension guide 5 there is a retraction device 40 with which the drawer 3 is pulled in the closing direction.

3 and 4 show the ejection device 6 in detail. In the two-part housing 20 a first guide path 21 for the carriage 15 is formed. The carriage 15 comprises two pegs 16 which are movable in a rectilinear guide path 21 . A pop-up stopper 10 accommodating a magnet 11 is arranged on the carriage 15 . The magnet 11 can be coupled to the angle driver 7 and hold the pop-up stopper 10 on the driver 7 fixed on the furniture body.

The pop-up stop 10 is adjustable in the closing or opening direction, wherein for this purpose the pop-up stop 10 has a threaded pin 12 which is guided through two eyelets 14 on the carriage 15 . The nut 13 is held between the two eyelets 15 and is rotatable, so that the pop-up stopper 10 can be moved by turning the nut 13 .

Formed on the carriage 15 is a first stopper 17 which is engageable with the bracket 26 in the ejection direction. A second stopper 18 is provided on the carriage 15 , which is spaced from the first stopper 17 by a certain distance and can be coupled with the bracket 26 in the closing direction. The second stopper 18 can be designed to be elastic and include an elastic piece 19 supported by the bottom of the receiving portion 25 for the second stopper 18 . Therefore, the second stopper 18 can be pressed into the carriage 15 against the elastic force of the elastic piece 19 . Furthermore, the stop 18 has a running surface on the part protruding from the carriage 15 .

Formed on the housing 20 is a second guide path 22 on which a carriage 26 of the ejection device 6 is movable. The bracket 26 comprises two pegs 27 (which engage in the guide path 22 ) and a protruding tip 28 (which can engage with the first stop 17 or the second stop 18 ). Here, the guide path 22 comprises an angled end, on which the bracket 26 is lockable by means of the elastic force of a spring 29 . The end of the spring 29 away from the bracket 26 can be fixed at different positions on the casing 20 or on components arranged on the casing 20, so that the force of the spring 29 can be adjusted.

A lever 30 is rotatably mounted on the housing 20 and engages with a shaft 31 in a receptacle on the housing 20 . The lever 30 has an arm 32 and an arm 33 on both sides of the shaft 31 . Arm 32 bears against second stop 18 in the closed position, while arm 33 of lever 30 bears against bracket 26 . The stop 34 and the stop 35 , which are designed in the form of a pin, act as a rotational deflection limiter for the rod 30 . The function of the stopper 35 is to prevent the rod 30 from detaching from the area of influence of the bracket 26 . Similarly, the function of the stopper 34 is to prevent the rod 30 from breaking away from the affected area of the stopper 18 on the carriage 15 . The stop 34 and the stop 35 thus increase the functional reliability of the ejection device.

In FIG. 5 the opening and closing device is shown in the closed position, wherein the front panel 4 is arranged at a small gap y from the furniture body 2 (see FIG. 13 ). In this case, the retraction device 40 on the pull-out guide 5 engages via a bracket 42 with a drive 41 which is fastened on a sliding rail of the pull-out guide 5 . The bracket 42 is installed so as to be movable along the curved guide on the housing 43, and is pulled toward the closing direction by the elastic force of the spring. Here, the spring is accommodated in a box 44 in which a damper may also be provided.

The retracting device 40 pushes the pushing element 3 in the closing direction, so that the housing 20 is also pushed in the closing direction.

Utilizing the spring force of the retraction means, the carriage 15 (supported by the pop-up stop 10 on the drive 7 and thus no longer movable along the guide path 21 ) acts on the arm 32 of the rod 30 . Thus, the lever 30 is tensioned clockwise due to the spring force of the retracting device 40 in FIG. The spring force of the spring 29 , which keeps the bracket 22 in the locked position, opposes the unlocking force by the retraction means 40 . Since the spring force of the spring 29 is significantly greater than the force of the retracting means 40, the bracket 26 remains in the locked position if no other force acts on the push element other than the retracting means 40.

Figure 6 shows the position of the opening and closing device when unlocked. The front panel 4 is slightly pressed into the furniture body 2 by a distance at most equal to the gap y. The ejection stopper 10 against the driver 7 and the carriage 15 of the ejection device move slightly in the closing direction. Furthermore, the drive 41 of the retraction device is moved slightly in the closing direction.

By pressing the front panel 4 in, the stop 18 on the carriage 15 turns the lever 30 in a clockwise direction so that the arm 33 of the lever 30 disengages the bracket 26 from the locked end position. Therefore, at this time, the elastic force of the spring 29 can move the bracket 26 along the guide path 22 . The bracket 26 engages with the first stopper 17 on the carriage 15 .

Figure 7 shows the opening and closing means in the ejected position. The front panel 4 is located at a position separated from the furniture body 2 . The retraction device 40 is pulled by moving the push element towards the opening direction, wherein the driver 41 has moved the bracket 42 along the guide path to the angled end, where the bracket 42 pivots and disengages from the driver 41 . The ejector 6 remains active, while the carriage 26 moves the carriage 15 in the opening direction.

In the position shown in FIG. 8 , the support 26 of the ejection device rests on the limiting element 23 and the latter is inserted into the housing 20 . The housing 20 has for this purpose a comb 37 (comb) with positioning lugs 38 into which the limiting elements can be inserted to provide the distances 51 to 55 relative to the bracket 26 . At this point, the carriage 26 has reached the end position and the carriage 15 can move further along the guide path 21 . In order not to make the slide frame 15 stay in this position all the time, the attractive force of the magnet 11 works at this moment, and the magnet 11 is coupled with the metal driving part 7 on the furniture main body. Accordingly, the carriage 15 continues to be pulled along the guide path 21 .

The carriage 15 in the position shown in FIG. 9 has now reached its end position on the guide path 21 . During the continued opening movement, the carriage 15 is pulled along the guide path 21 , wherein the second stop 18 moves beyond the tip 28 of the bracket 26 . Against the force of the spring tab 29 , the stop 18 is briefly pressed into the carriage 15 , while the stop 18 with its running surface moves over the tip 28 of the support 26 . Subsequently, the elastic force of the elastic piece snaps the block 18 behind the tip 28 of the bracket 26 .

In this position, the push element 4 can move freely towards the opening direction, wherein the ejection device 6 and the retraction device 40 are disengaged, and at this time only the attraction force of the magnet 11 on the drive part 7 has to be overcome, and the drawer 3 The inertial forces are usually sufficient for this purpose.

In FIG. 10 , the push element moves further in the closing direction, wherein first the spring 29 of the ejection device 6 is tensioned. For this purpose, the second stop 18 engages on the bracket 26 and moves it as far as the angular end of the guide path 22 . When the bracket 26 reaches the angled end, it pushes the rod 30 in a counterclockwise direction. Additionally, the tip 28 of the bracket 26 disengages the second stop 18 , which is now movable past the bracket 26 .

Since the drive member 41 is located a short distance in front of the bracket 42, the retraction device 40 is still disengaged.

In the position shown in FIG. 11 , the retracting device 40 has started to work, and the driving member 41 is engaged with the bracket 42 , at this time, the driving member 41 is moved in the closing direction by the elastic force of the retracting spring. The ejection device 6 is in a tensioned state in which the carriage 15 moves along the guide path 21 .

In FIG. 12 the closed position is reached, which is also shown in FIG. 5 . The second stop 18 now bears against the arm 32 of the lever 30 , while the opposite arm 33 bears against the bracket 26 . Since the retaining force induced by the spring 29 is greater than the triggering force of the retraction device 40, the push element remains stably in the closed position.

In order to be able to adjust the gap y between the front panel 4 and the furniture body 2 ( FIG. 13 ), an adjustment mechanism with an adjustment offset V is provided on the carriage 15 for the ejection stop 10 .

According to A to C of FIG. 14 , the pop-up stopper 10 can be moved toward the closing or opening direction by rotating the nut 13 . Thus, the gap y forming the panel gap is adjusted by the offset s or t shown (s+t=V). Adjustment of the panel clearance is selectively carried out with an open or closed push element, wherein with the open push element, the nut 13 on the bottom side of the drawer is more accessible.

FIG. 16 shows a force-distance diagram for the closing process of the opening and closing device according to the invention. The closed position is provided on the left, in which the retraction device 40 applies a pulling force to the push element. The ejection device 6 acts at a distance from the retraction device 40, which is tensioned during closing so that a closing force has to be applied.

Figure 17 shows a force-distance diagram for the opening process. Since the ejector acts in the closed position immediately after unlocking, the triangle tensioning the ejector is now offset. Since the opening force of the ejection means is significantly greater than the closing force of the retraction means, the pushing element 3 is ejected.

Figure 17 shows that the spring force triangle of the ejection device can be broken down into different parts. The maximum spring force and spring deflection can be adjusted. In order to improve the recoverable energy and spring deflection of the spring 29 , according to FIG. 18 the delimiting element 23 can be fixed in five different positions, distances 51 to 55 . Furthermore, the range of action of the ejection device 6 can be adjusted by selecting the length of the limiting element 23 .

The opening and closing device can be optimized for different intended uses due to the user's discomfort if too much ejection and pulling force is required. More precisely, smooth opening and closing can be achieved. For relatively heavy push elements such as sliding doors and wide drawers, higher ejection forces are required compared to light furniture parts. In this regard, the effective spring force and effective ejection distance of the ejection device can be optimized for each intended use by selecting an appropriate ejection device.

FIG. 19 shows a modified embodiment of an ejection device 6 ′ according to the invention, mounted on the bottom side of a drawer 3 . As in the previous exemplary embodiment, a pull-out guide is accommodated in the side panel 8 of the drawer 3 , in which a retraction device 40 is also arranged.

Figure 20 shows the ejection device 6' in the closed position of the movable furniture part. The housing 20' forms a first guide path 21' of the carriage 15'. The carriage 15' is movably held in the linear guide path 21' by means of a peg 16' and has an ejection stop 10' which pushes against the drive 7'.

The pop-up stop 10 is integrally formed with the carriage 15', wherein an adjustment mechanism as described in the previous exemplary embodiments can also be provided.

A first stopper 17' is formed on the carriage 15', which engages with the bracket 26' in the ejection direction. A second stop 18', spaced apart from the first stop, is provided on the carriage 15', which can be coupled with the bracket 26' in the closing direction. The stopper 18' is elastic and supported on the carriage 15'. The stop 18' can thus be pressed into the carriage 15' against the force of the spring. The stop 18' also has a running surface on the part protruding from the carriage 15'.

Formed on the housing 20' is a second guide path 22' having a rectilinear middle portion and two angled ends, on which a carriage 26' of the ejector is movable. The bracket 26' is guided on the guide path 22' by means of two pegs and has two spaced apart protruding tips, one of which engages the first stop 17' or the second stop 18'. The second point can be used to unlock the bracket 26' if the pawl 17'' on the carriage 15' pushes against the point and is unlocked by pulling the movable furniture part 3. The pawl 17'' is also resilient and is formed with a running surface which snaps behind a tip on the bracket 26'.

The guide path 22' comprises an angled end on which the bracket 26' can be locked by the elastic force of a spring 29'. In order to be able to adjust the elastic force of the spring 29', the spring 29' can be fixed at different positions on the housing 20' or on components arranged on the housing 20' at the end away from the bracket 26'.

The rod 30' is rotatably mounted on the housing 20' and engages with the shaft 31' in the housing 20' in the housing 20'. On either side of the shaft 31', the rod 30' has an arm 32' and an arm 33'. In the closed position the arm 32' bears against the stop 18', while the arm 33' of the lever 30' bears against the bracket 26', whereby rotational deflection can be limited by providing a stop on the housing 20'.

Furthermore, a latch 61 is movably mounted on the carriage 15'. The latch 61 has a pin 62 which is guided in a groove 63 arranged perpendicularly to the direction of movement of the carriage 15' and in a third guide path 60 on the housing 20'. As the latch 61 moves with the carriage 15', the latch 61 can be raised and lowered.

Figure 20 shows the opening and closing device in the closed position. As in the first exemplary embodiment, the retraction device 40 on the pull-out guide 5 engages with the drive 41 via the bracket 42 , which is fixed on the sliding rail of the pull-out guide 5 . The bracket 42 is installed so as to be movable along the curved guide on the housing 43, and is pulled toward the closing direction by the elastic force of the spring. The spring is housed within a box 44, within which a bumper may also be provided. The retracting device 40 pushes the push member 3 in the closing direction, so that the housing 20' is also pushed in the closing direction.

Due to the spring force of the ejection device, the carriage 15' acts on the arm 32' of the rod 30', wherein the carriage 15' is supported on the drive 7' by the ejection stop 10' and therefore cannot continue along the guide path 21 'move. Thus, the lever 30' is tensioned in the counterclockwise direction due to the spring force on the retraction device 40 and pushes the bracket 26' with the arm 33' to move the bracket out of the angled end of the guide path 22' and unlock it. The spring force of the spring 29 ′, which keeps the bracket 26 ′ in the locked position, opposes the unlocking force by the retraction means 40 . Since the spring force of the spring 29' is significantly greater than the force of the retracting means 40, the bracket 26' is held in the locked position if no other force is exerted on the push element other than the retracting means 40.

Figure 21 shows the position of the opening and closing means when unlocked. To this end, the front panel 4 is slightly pushed into the furniture body 2 . The ejection stop 10' abutting on the drive member 7' and the carriage 15' of the ejection device move slightly towards the closing direction. Furthermore, the drive 41 of the retraction device is moved slightly towards the closing direction.

Thus, the lever 30' is rotated clockwise by the stop 18' on the carriage 15' so that the arm 33' of the lever 30' moves the bracket 26' out of the locked end position. Therefore, at this time, the bracket 26' is moved along the guide path 22' by the elastic force of the spring 29'. The bracket 26' engages with the first stop 17' on the carriage 15'.

Figure 21 shows the opening and closing device in the ejected position. The front panel 4 is at a certain distance from the furniture body 2 . The retraction device 40 is tensioned by moving the push element towards the opening direction, wherein the driver 41 has moved the bracket 42 along the guide path to the angled end, on which the bracket 42 pivots and is decoupled from the driver 41 (Fig. twenty two). The ejection device 6' is still active and the carriage 15' is moved in the opening direction by means of the bracket 26'. By moving the carriage 15' towards the opening direction, the latch 61 moves along the third guide path 60, which extends in a diagonal direction to the first guide path 21' of the carriage 15' to move the latch 61 slowly downwards.

Figure 23 shows the position in which the bracket 26' of the ejector reaches and pivots at the second angular end of the guide path 22'. The carriage 15' is thus detached from the bracket 26'. The carriage 26' has reached the end position and the carriage 15' continues to move along the guide path 21'.

In order to make the carriage 15' not stay in this position, at this moment, the driving member 7' comes into play, and it will continue to pull the moving carriage 15' along the guide path 15'. For this reason, the latch 61 is pressed against the driving member 7. ' to hold the carriage 15' on the drive member 7'.

Figure 24 shows the position of the carriage 15' on the guide path 21' in its end position. In a further opening movement, the carriage 15' is pulled along the guide path 21', wherein the second stop 18' moves past the tip of the bracket 26'. The stop 18' is briefly pressed into the carriage 15' against the force of the spring, and the stop 18' having a running surface moves over the tip of the support 26'. The stop 18' is then locked behind the tip of the bracket 26'. Furthermore, the latch 61 is now fully retracted into the carriage 15', whereby the carriage 15' is decoupled from the driver 7' and can leave the slave driver 7' together with the housing 20'.

In this position, the push element 4 is free to move in the opening direction, wherein the ejection means 6' and the retraction means 40 are disengaged.

In FIG. 25 , the push element is moved again in the closing direction, wherein the spring 29 ′ of the ejection device 6 ′ is first tensioned. To this end, the second stop 18' engages on the bracket 26' and moves it to the angular end of the guide path 22'. Shortly before the bracket 26' reaches the angled end, the driver 41 reaches the bracket 42 and unlocks it from the end position. Thus, the retracting means 40 act and pull the push element in the closing direction.

When the bracket 26' reaches the angled end of the guide path 22', it pushes the rod 30' clockwise. Furthermore, as shown in FIG. 27, the tip of the bracket 26' disengages the second stop 18', which is now able to move past the bracket 26'.

Figure 28 shows the position in which the retraction means 40 is activated and the bracket 42 is moved along the guide path by the elastic force of the retraction spring. The ejection device 6' is in tension, wherein the carriage 15' moves along the guide path 21'. The latch 61 is thus moved upwards again and places the driver 7 ′ between the pop-up stop 10 ′ and the latch 61 . During the closing movement, the pawl 17'' arranged on the carriage reaches the tip of the bracket 26' with the running surface and engages behind it. Thus, unlocking of the bracket 26' can also be achieved by pulling the thrust element.

In FIG. 29 , the closed position has been reached, which is also shown in FIG. 20 . At this point, the second stop 18' bears against the arm 32' of the lever 30', while the opposite arm 33' bears against the bracket 26'. Since the retaining force caused by the spring 29' is greater than the triggering force caused by the retracting means 40, the thrust element remains stably in the closed position.
