Description

Clamping element to position a furniture cover

The invention relates to a fastener, especially a positioner of a cover, to position a cover of a piece of furniture between a closed position and an open position. The clamping element is used to position a cover, which is not connected directly through hinges with a body of the furniture.

Such a clamping element is shown in DE 10 2008 005 463 A1, in which a spring force accumulator acts only indirectly on the operating lever. The adjustment lever is held on the actuating lever rotatably around an adjustment axis, the adjustment axis being located, with reference to the force accumulator force line of action, on the side opposite to the axis of rotation, around which the operating lever is rotatably supported on the body part of the hardware. In this case, the adjustment lever is held in an area of the end of the operating lever, and is inclined in the direction of the rotation axis.

The objective of the present invention is to make available a fastener with a simple structure, which has improved characteristics with respect to its adjustability in supporting the force of the positioning movement of the lid.

According to the invention, this objective is achieved through a clamping element to position a cover of a piece of furniture between a closed position and an open position, comprising a first piece of hardware, which can be joined with the body of a piece of furniture. , a second piece of hardware, which can be joined with the cover, a first support arm, which is attached to the first piece of hardware rotatably around a first axis of the body, and is attached to the second piece of swivel fittings around a first axis of the lid; a second support arm, which is attached to the first piece of hardware rotatably around a second axis of the body, and is attached to the second piece of hardware rotatably around a second axis of the lid; a drive lever, which is fastened to the first piece of hardware rotatably around an axis of rotation; an adjustment arm, which is attached to the operating lever, at a distance from the axis of rotation, rotatably around a third axis of the body, and which is attached to the second piece of hardware rotatably around a third axis of the lid; a force actuation, which is supported by one part against the first piece of hardware, and on the other hand acts with a force on the operating lever in a first direction of rotation, as well as adjustment means to position the line of action force dynamics according to which the force actuation acts on the actuation lever, the adjustment means comprising an adjustment lever, and that adjustment lever being rotatably attached to the first piece of hardware, between the dynamic action line of force and the third axis of the body.

This configuration has the advantage that the area in which the effective lever arm can be adjusted is clearly increased. Through the effective lever arm, the drive lever acts on the force accumulator around the axis of rotation. The dynamic force action line of the force accumulator is rotated through the positioning of the adjustment means, and the length of the effective lever arm is modified. The increase of the adjustment zone is possible because the adjustment lever is now effective only in one area of the end of the actuating arm, and is held between the dynamic force action line of the force accumulator and the third axis of the body. Because, according to the invention, the area of the effective lever arm is enlarged, the force drive can be dimensioned more weakly, in order, however, to generate the same turning moment in the axis of rotation of the drive lever Furthermore, with a greater adjustment area of the effective lever arm, the positioning of the dynamic force action line, or the lever arm, can take place more sensitively, since an adjustment of the dynamic action line of force in a given dimension, with reference to a larger effective lever arm, results in a proportionally smaller modification. The spectrum of the action of the force on the actuating lever generated by the force actuation can also be increased, through the greater effective lever arm. Through this, lids of a higher weight range can be positioned through the positioning element according to the invention. The adjustment lever is preferably placed on the operating lever.

Specifically, it can be provided that the adjustment lever is fastened to the actuating lever rotatably around the axis of rotation. Especially, the drive lever can be connected to the first piece of hardware through a support stump, and the adjustment lever is attached to the drive lever through the support stump. This results in a simple structure, since a single support point can be used for two levers. In addition, as a continuation of an advantageous configuration, the actuating lever may have a U-shaped cross section, in which the adjustment lever is housed, at least partially.

Advantageously, the force drive is rotatably supported, on the one hand, on the first piece of hardware, and on the other hand, by means of support, on at least one support surface of the adjustment lever and at least one clamping surface of the operating lever. By means of the support of the force drive on the first piece of hardware, and the support means, an action line is defined

force dynamics of the force drive. In this case a support stump can be provided as a means of support. Preferably, the distance of the dynamic force action line to the axis of rotation is modifiable through the relative rotation of the adjustment lever with respect to the actuation lever. This ensures, advantageously, that the force accumulator acts directly on the drive lever, and that the adjustment lever serves to adjust the effective length of the lever arm.

Preferably, the support surface of the adjustment lever and the clamping surface of the operating lever form an acute angle to each other. In this case, the support surface is inclined especially in the direction of the axis of rotation, such that the support stump of the force drive is subjected to a component of the force against the holding surface. With this, the support stump is embedded and secured securely between the support surface and the clamping surface, which prevents the support stump from sliding on the support surface in the direction of the axis of rotation. It is understood that the support surface of the adjustment lever, or the clamping surface of the actuation lever, can be flat or pumped surfaces, which are specially adjusted to each other. For example, the clamping surface may be the side edge of an elongated hole of the actuation lever, in which the support means of the force actuation are guided. The elongated hole may be executed with a straight or slightly curved shape.

According to a preferred configuration, positioning means are provided by means of which the adjustment lever can be positioned in different rotational positions with respect to the actuating lever. Preferably, the positioning means are placed in the actuating lever, and support the control lever. adjustment in front of the operating lever. The positioning means may be configured in the form of a screw that is attached to the operating lever by means of a thread and acts on the adjustment lever. Preferably, the positioning means are positioned between the axis of rotation and the dynamic force action line of the force drive. For good accessibility, the positioning means may be placed at the bottom of the operating lever.

The first piece of hardware preferably has a projection that runs predominantly parallel to a base, and on which the two support arms, the operating lever and the adjustment lever are supported. Preferably, the projection is formed from the base plate of the first piece of hardware. Through this conformation an increased solidity results for the area of the projection. The first piece of hardware is preferably a piece formed of sheet metal.

Preferably, the actuating lever is also configured as a sheet formed part. This results in a simple structure, with favorable manufacturing and assembly.

Especially, the adjustment arm may have a U-shaped cross section, in which the first support arm is housed, at least partially. Through the cross sections in the form of Upuede, the danger of imprisonment, for example of hands or fingers, in handling can be reduced and even avoided. The adjustment arm is preferably a shaped piece of sheet metal.

In order to increase the comfort of handling, a shock absorber can be provided that dampens the turning movement of the cover until it reaches the closed position, the shock absorber being housed in a housing attached to the first support arm. An interchangeable shock absorber has the advantage that, if necessary, the shock absorber can be exchanged for another shock absorber with other characteristics.

Specifically, the shock absorber comprises a shock absorber body, axially movable in relation to the housing, which acts in conjunction with a stop element of the first hardware. It is preferred that the stop element is configured in one piece with the first piece of hardware, through which a simple fabrication results, and the number of construction parts is kept reduced.

Preferably, the first support arm also has a U-shaped cross-section, in which the shock absorber is partially housed, which is preferably configured as a sheet formed part.

In the adjustment arm, stop means may be provided on which the first support arm is supported, and by which a rotation position of the first support arm can be adjusted in relation to the adjustment arm. Preferably, the abutment means are positioned on the adjusting arm displaceably. Through the stop means, at least two different positions of the second piece of hardware, referring to a horizontal position, can be pre-adjusted advantageously. Preferably, the second piece of hardware is in an approximately hot-horizontal position of the abutment means, and in a steeper step on, for example, 10 ’. This adjustability offers advantages when fixing the cover on the second piece of hardware.

In the opening position of the clamping element, the stop means support the first support arm in a first position of movement through a first support surface and under a first angle, and in a second position of movement to the first arm of support through a second support surface, under a second lower angle.

A preferred exemplary embodiment is clarified in more detail according to the following figures in the drawings. In

they are shown:

Figure 4 a side view of the fastener according to Figure 1 in a closed position, and

Figure 5 A side view of the opposite side of the fastener element of Figure 1, in the open position, with a first anchor piece schematically represented.

Figures 1 to 5 show the fastener according to the invention in various views and in various positions, and are described below together.

The clamping element has a first piece of hardware 1, which can be held on an inner side of a body of a piece of furniture, not shown. The clamping element further comprises a second piece of hardware 2, which can be held on the furniture cover, not shown. The lid is connected to the body only through the fastener, and has no hinge with respect to it. As explained below, the cover rotates around an axis that moves in space and is dependent on the structure of the fastener.

The clamping element has a first support arm 5 and a second support arm 6 for joining the cover with the body. The first support arm 5 is configured as a U-profile in the cross-section, and is attached to the first piece of hardware 1 on the side of the body, rotatably around a first axis 7 of the body, and to the second piece of fitting 2 on the side of the lid, rotating around a first axis 8 of the lid. The second support arm 6 is attached to the first piece of hardware 1 on the side of the body, rotatably around a second axis 9 of the body, and to the second piece of hardware 2 on the side of the cover, rotatably around a second axis 8 of the lid.

The support arms 5, 6 are not placed parallel to each other. This means that a first plane 29, which contains the first axis 7 of the body and the first axis 8 of the lid, and a second plane 30, which contains the second axis 9 of the body and the second axis 10 of the lid, they cut each other in a rotation axis 11. The cover rotates around that axis of rotation 11, the axis of rotation 11 moving in space, as can be seen in Figures 1, 3 and 4.

In order for the lid to be held in any position through a widest possible range of rotation angles, a force drive is provided in the form of a spring accumulator 12. The spring accumulator 12 has a base element 14 , which is attached to the first piece of hardware 1 on the side of the body rotatably around a support axis 13. In the base element 14 an adjustment slide 15 is attached axially movable along an axis of displacement. In this case, the displacement axis defines the dynamic force action line 16 of the spring accumulator 12. The adjustment slide 15 is subjected to a force by means of pressure springs 17, which are supported on the one hand against the base element 14, and on the other hand against the adjustment slide 15, in the direction of an outwardly displaced position. In order that the pressure springs 17 do not bend perpendicularly to the axis 16 of displacement, a pin 18 is introduced in the adjustment slide 15, for each pressure spring 17, which is inserted into a twist of the pressure springs 17 , configured as helical springs, and supporting the respective pressure spring 17 against a lateral bulge.

The drive comprises a drive lever 19, with an approximate L-shape, which is configured as a U-shaped profile seen in its cross-section, as seen in Figures 2a and 2b. The actuation lever 19 is supported with its first wing 23, approximately half of the same wing, on a support stump 22 which is connected to the first piece of hardware on the side of the body, rotatably around a rotation axis. 20. The drive lever 19 has in its first wing 23 through holes 21, 21 'through the side walls of the U-shaped profile, by which the drive lever 19 is fixed on the support stump 22. About the first wing 23 is attached to an adjustment arm 26 with the actuation lever 19, in an area of its end, rotatably around a third axis 27 of the body, the third axis 27 of the body being placed at a certain distance from to the rotation axis 20. The adjustment arm 26 is configured as a U-profile, like the first support arm 5, and is also rotatably attached around a third axis 28 of the cover, to the second part of hardware 2 side of the lid. In the folded state, the first support arm 5 is partially sunk in the profile of the adjustment arm 26, as can be seen in Figure 4.

The second wing 24 respectively has, on its two side walls, an elongated hole 42, 42 ', which are congruent with each other with respect to the axis 20 of rotation. The elongated holes 42, 42 ’run in such a way that their distance to the axis of rotation 20 increases, starting from the first wing 23 to an area of the end of the second wing 24. With

reference to a line through the axis of rotation 20 and the third axis 27 of the body, the elongated holes 42, 42 ’run approximately at an angle of 60 °, another angle value may also be provided.

In the U-shaped profile of the drive lever 19, an adjustment lever 25 is also fastened on the support stump 22 and rotatably around the axis 20, as can be seen in Figures 2a and 2b. Thus, the actuation lever 19 and the adjustment lever 25 are rotatable with each other around the axis of rotation 20, the adjustment lever 25 being able to be fixed without steps in different rotational positions with respect to the actuation lever, as observed by one part in figure 1, and on the other hand in figures 3 and 4. The adjustment lever 25 extends from the support stump 22 to the interior of the longitudinal holes 42, 42 'of the actuation lever 19. To adjust the position of the adjustment lever 25, adjustment means are used in the form of an adjustment screw 31, which is screwed into a threaded hole 32 of the operating lever 19. The adjustment screw 31 serves as a stop for the lever of adjustment 25.

The adjustment slide 15 of the spring accumulator 12 is supported by a support stump 43, which is housed in the elongated holes 42, 42 ’, on the adjustment lever 25 and the actuation lever 19. For this, the adjustment lever 25 forms bearing surfaces 44, 44 ', and the actuation lever 19 holding surfaces 45, 45' in the elongated holes 42, 42 ', and both run towards each other in the direction of the axis of rotation 20. In this case, the bearing surfaces 44, 44 'are inclined in the direction of the axis of rotation, so that they, together with the clamping surfaces 45, 45', imprison the support stump 43, which otherwise, and in the case that there was no support on the clamping surfaces 45, 45 ', would slide on the bearing surfaces 44, 44' in the direction of the axis of rotation 20.

The dynamic force action line 16 of the spring accumulator 12, which corresponds to its axis of displacement, is oriented in such a way that a moment of rotation on the operating lever 19 in a clockwise direction originates. , according to the representation of figure 1, through the adjustment lever 25, under a support on the actuation lever 19 and the adjustment screw 31. The adjustment arm 26 is positioned such that it is subjected to pressure by the weight of the cover, and generates a turning moment in the counterclockwise direction on the operating lever 19, according to the representation of figure 1. In this case it is guaranteed, through a range of rotation of the cover as much as possible, that the turning moments, which are exerted on the operating lever 19 on the one hand by the spring accumulator 12, and on the other hand by the cover, compensate each other, that is, they are in equilibrium , so that the lid is held in the respective turning position. The turning range in which the cover is held in each turning position preferably reaches from the opening position according to Figure 1 to a neutral position in which the dynamic force action line 39 of the adjusting arm 26, along which the force of the adjusting arm 26 is applied on the second piece of hardware 2, it is cut with the axis of rotation 11, which approximately corresponds to the position of rotation according to Figure 3.

The first piece of hardware 1 has a projection 4, which runs predominantly parallel to a base plate 3, on which the two support arms 5, 6, the operating lever 19 and the adjustment lever 25 are supported The protrusion 4 is formed on the base plate 3 of the first piece of hardware 1, so that here an increased solidity results for the support of the support arms 5, 6 and of the levers 19, 25.

Over the range of angles of rotation, from the opening position to the neutral position, cross the dynamic force action line 39 of the adjustment arm 26 of the rotation axis 11, around which the lid rotates at such a distance that a turning moment is generated clockwise on the cover, according to the representation of figure 1. The generated turning moment acts on the cover in the direction of the opening position. In the neutral position of the cover, the dynamic force action line 39 of the adjustment arm 26 cuts to the axis of rotation 11, so that no turning moment is generated on the cover by the adjustment arm 26 Over the range of turning angles, from the open position to the closed position, cross the dynamic force action line 39 of the adjusting arm 26 of the rotation axis 11 at a distance such that a turning moment is generated counterclockwise on the cover, according to the representation of figure 4. The moment of rotation generated thus acts on the cover in the direction of the closed position. With this, in a range of turning angles shortly before reaching the closed position, a tightening moment acts on the cover, so that the cover is held securely in the closed position.

To adjust the turning moment that is exerted by the spring accumulator 12 through the adjustment lever 25, under the support on the actuation lever 19, and by the adjustment screw 31 on the actuation lever 19, can be adjusted without steps, through the adjustment screw, different rotational positions of the adjustment lever 25 relative to the actuation lever. By rotating the adjustment lever 25 according to the clockwise direction, assuming the drive lever 19 is fixed, by unscrewing the adjustment lever of the actuation lever 19, the cut-off point of the bearing surfaces 44 , 44 'and of the clamping surfaces 45, 45' moves in the direction of the axis of rotation 20. This is also valid for the support stump 43, which travels more and more towards the first wing 23, with reference to the elongated holes 42, 42 ', and thus rests on the bearing surfaces 44, 44' and on the clamping surfaces 45, 45 'at a smaller distance from the axis 20 of rotation. With this, the distance between the dynamic force action line of the spring accumulator 12 on the adjustment lever 25 and the rotation axis 20 can be adjusted. The effective lever arm with which a

The moment of rotation by the spring accumulator 12 on the operating lever 19 can be modified.

However, in addition to this modification of the effective lever arm, a modification of the previous tension of the spring accumulator 12 also takes place. As the support stump 43 approaches the axis 20 of rotation, through the rotation of the adjustment lever 25 clockwise in relation to the drive lever 19, it also increasingly separates the support shaft 13 from the spring accumulator 12, so that the pressure springs 17 are increasingly relaxed . Because according to the invention, a greater effective lever arm can be used, and at the same time with the reduction of the lever arm the previous tension of the spring is reduced, or with the increase of the lever arm the previous tension of the spring is increased spring, a wider spectrum of spring forces can be used. This means that a greater range of covers weights can be supported with the fastener.

A shock absorber 34 is provided on the first support arm 5. It is preferably a shock absorber 34 having a housing 35, which is detachably attached to the first support arm 5. For this, the housing 35 has several projections 51 of insert, which are introduced with positive connection in hooks 52 of the first support arm. A damping body 36 has been fastened axially in the housing 35, the damping body 36 being subjected to a force until an outwardly pushed position, shown in FIG. 1, is provided. Spring means can be used for this purpose. which are placed in the housing 35, and which are supported on the one hand against the housing 35, and on the other hand against the damping body 36. The first piece of hardware 1 on the side of the body configures in one piece a stop element 37, which has a stop surface 38. In the opening position (figure 1) of the cover, the damping body 36 is not resting on the top surface 38.

When the cover is moved to the closed position (figure 4), the damping body 36 approaches the abutment surface 38 until it rests on it. The damping body 36 preferably rests on the abutment surface 38 only when the cover is between the neutral position and the closed position, that is, when a tightening moment is exerted on the cover. Once the damping body 36 has been supported on the abutment surface 38, the damping body 36 is introduced into the housing 35, against the damping force, when the rotation of the cover is continued until reaching the position of closure, so that the tightening of the lid on the body is cushioned. The shock absorber 34 may have other damping means. Thus, the shock absorber can be configured as a hydraulic cylinder.

In the adjustment arm 26, stop means 46 are provided on which the first support arm 5 rests, and by means of which a rotation position of the first support arm 5 can be adjusted relative to the adjustment arm

26. The stop means 46 are positioned displaceably on the floor 49 of the adjustment arm 26, U-shaped. On the side facing the first support arm 5, the stop means 46 have two bearing surfaces 47 , 48 which run approximately parallel to the floor 49 of the adjustment arm 26, and of which the first support surface 47 is at a greater distance from the floor 49 than that of the second support surface 48. According to each position of displacement, one of the support surfaces 47, 48 is in contact with a support surface 50 of the first support arm 5, which is placed in the area of the first axis of the cover 8, oriented towards the arm 26 of juste. If the stop means 46 are moved in the direction of the axle 28 of the cover, to the position not shown where the second support surface 48 is in contact with the support surface 50 of the first support arm 5, the arm of adjustment 26 has turned until it is closer to the first support arm 5, and the second piece of hardware 2 has turned more upwards, about 10 ° from the horizontal, around the first axis of rotation 8 of the cover. In this case, as horizontal, it refers to a position in which the lid is in the opening position, and is forming a right angle, that is to say at 90 ° with respect to a vertical edge of limitation of the first piece of hardware 1.
