Abstract

The holder has safe-deposit box (16). The holder is movable between closing position (18) of a safe-deposit box into a furniture body (12). The two independent pressure accumulators (28,36,37,29,43,44) are assigned to the corpus side end region of the operating lever (24). The opening motion of the furniture flap supports an energy accumulator predominantly and does not exert swivel movement, in a swivel area of the clamping position up to a dead center position. The other energy accumulator exerts clamping force particularly in the swivel area of the closing position up to the dead center position.

Description

The invention relates to a folding lid support for a folding furniture lid, which can be moved between a closed position, which closes a cabinet shelf in a furniture body, and an upwardly displaced opening position, with the less a maneuvering lever, which has been stationary articulated, on the one hand, in the furniture body by means of a tilting shaft and, on the other, in the folding lid of the furniture.

A folding lid support of this kind is known, for example, from DE 10 2004 019 785 A1, presenting the hinged lid hardware disclosed therein, an eccentric cam with respect to the first axis of maneuver in the extreme area of the maneuvering lever, which faces the first maneuvering axis, cam that influences according to the force on the behavior of the movement of the flip cover and to which a thrust piece attached by an elastic mechanism against the cam has been associated , so that the thrust piece exerts a torque on the operating lever independent of the rotating position of the operating lever. In this genre of hinged lid fittings, it is possible to achieve, by means of a conveniently chosen path of the cam, that the collapsible cover is held by itself practically in each intermediate position of its travel from the closed position to the position of opening. Accordingly, the force to be applied by the user to open and close is reduced. The cam has been contoured so that, in a lower neutral position, a closing force is exerted, which holds the flip cover in the closed position by means of the thrust piece.

In this type of folding lid supports, the elastic force is adapted to the weight of the folding lid, that is to say that in a heavy folding lid of a piece of furniture, the elastic mechanism must apply a high elastic force to be able to introduce a large pair of turn in the direction of opening, acting against the heavy weight of the flip lid. Since the cam has been contoured so that a change in torque takes place after exceeding

or of being below the neutral position, the elastic force of the elastic mechanism also acts on the closing force in the closing position. The folding lid of the furniture is also held, accordingly, in the closed position with a relatively large closing force, which must then be overcome by the user when opening to the neutral position.

In document US-A-3820866, a door control system for a dishwasher door has been disclosed. The gate to open forward by way of a folding furniture cover has a maneuvering lever that, on the one hand, has been stationary articulated in the body of the furniture by means of an axis of rotation and, on the other, in the gate, having been assigned to the extreme area of the maneuvering lever, which gives the body of the furniture, at least two energy accumulators, which act independently of each other, in the form of traction springs, of which an energy accumulator mainly reinforces the opening movement of the folding lid of the furniture and exerts almost no torque in a turning radius from the closed position to a neutral position, while the other energy accumulator exerts a closing force, above all, in the turning radius from the closed position to the neutral position.

It is a problem of the invention to create a folding lid support of the kind mentioned at the beginning, in which the incident closing force on the folding lid of the furniture is a force acting independently of the force acting in the opening direction.

This problem is solved by means of a collapsible lid support with the features of independent claim 1. Improvements of the invention have been presented in the dependent claims.

The folding lid support according to the invention is characterized in that a maneuvering disc is assigned to the end of the maneuvering lever that gives the body of the furniture, with a first bend zone, to which a first thrust piece has been assigned held by a first elastic mechanism against the curve zone, the first curve zone presenting an eccentric curve section with respect to the axis of rotation, so that, when the thrust piece is exceeded, it is exerted on the folding cover of the furniture a turning torque opposite to the weight of the operative flip cover in the direction of opening; the maneuver disc presenting a second curve zone, to which a second thrust piece is assigned held by a second elastic mechanism against the second curve zone; the second curve zone having an eccentric curve section with respect to the axis of rotation so that, when the second thrust piece is exceeded, a torque is exerted on the folding cover of the operating furniture in the closing direction; the first curve zone presenting a circular arc-shaped curve section and the second curve zone, a circular arc-shaped curve section or another additional eccentric curve section, which exerts a torque, when the second is exceeded thrust piece, operating in the direction of opening; and being attached, in the closing area of the folding lid of the furniture, the first curve zone with its circular arc-shaped curve section to the first thrust piece, and the second curve zone being attached with its section of eccentric curve to the second thrust piece, and being attached, by opening the flip cover immediately next to the closure zone, the first curve zone with its eccentric curve section to the first thrust piece and the second curve zone with its circular arc-shaped curve section or with its other additional eccentric curve section, to the second thrust piece.

In the eccentric curve sections, then, twist pairs can be transmitted to the folding lid of the furniture, while in the circular arc-shaped curve sections basically no torque can be introduced. While, for example, in the first curve zone the eccentric curve section is "in action" and a torque is exerted by means of the first associated thrust piece, it may be "in action" in the second zone of curve the curve section in the form of a circular arc or the additional eccentric curve section, so that it does not, in this case, basically exert any torque or an additional torque operating in the opening direction. For the force in the opening direction, therefore, the elastic force of the first elastic mechanism and the contouring of the first curve zone with support, if necessary, of the second elastic mechanism may be competent if the second Thrust piece is in the additional eccentric curve section, while, independently of it, for the retention or closing force in the closing position only the elastic force of the second elastic mechanism is available.

In an improvement of the invention, the two curve zones have been made in two mutually opposite contour regions of the operating disc.

It is possible that in at least one of the two curve zones, an end stop associated with the opening position for the associated thrust piece has been provided. Thanks to this, it is avoided that the folding lid of the furniture can continue to be rotated beyond the opening position. Preferably, a final stop is provided in both the first and the second curve zones. The final stop may be formed, for example, by a trough-shaped concavity in the operating disc. It is also obviously possible to make a shoulder instead of the concavity in the maneuvering disc.

The two elastic devices can be coupled, respectively, on the one hand, stationary with a hardware plate mounted on the furniture body and, on the other, with the operating disc by means of a first or a second energy transmitting element, that support the first or second thrust pieces. The first energy transmitting element may be formed, for example, by a support of the thrust piece rotatably supported on the hardware plate. The second energy transmitting element is preferably formed by a pivoting lever resting on the hardware plate.

In order to avoid a violent collision of the folding lid of the furniture with the cabinet body when entering the closing position, a damping mechanism can be provided in the region of the end of the maneuvering lever that gives the body of the furniture. Especially preferred, the damping mechanism is located between the pivot lever and the hardware plate, and can be actuated by the pivoting movement of the pivoting lever. The damping mechanism can be stationary arranged on the pivot lever and have a drive piece, which can be pressed on a drive shoulder configured in the hardware plate.

In an improvement of the invention, the maneuvering disk is formed by two pieces of disk, which cover on both sides the end of the lever that gives the body of the furniture. It is possible, alternatively, to make the maneuver disc one piece, and the maneuver lever can then be arranged to the left or right of the maneuver disc.

A preferred embodiment of the invention has been shown in the drawing, which is explained in more detail below. The figures show in the drawing:

Figures 1 to 6 show a preferred embodiment of the folding lid support 11 according to the invention. The folding lid support 11 has been arranged in a cabinet, especially the upper part of the cabinet, which is fixed by hanging it in height on a building wall. The body 12 of the cabinet cabinet has two mutually opposite vertical side walls 13, of which only one can be seen in the drawing, a bottom 14, a roof 15 and a rear wall, and contains a cabinet shelf 16 delimited by those walls. To the front of the shelf 16 of the cabinet, a collapsible furniture lid 17 has been associated with it, which adopts a vertical state in its closed position 18 resulting from Figure 1 and closes the shelf 16 of the cabinet. The folding lid 17 of the cabinet can be moved from said closing position 18 to an opening position, which allows access to the shelf 16 of the cabinet, the opening movement being carried out up through the intermediate positions shown in Figures 3 and

5. The folding furniture cover 17 is described below, by way of example based on a two-piece folding furniture cover 17, which could also be called a folding cover. Obviously, the folding furniture cover 17 according to the invention could also be installed in combination with a one-piece furniture folding lid 17.

The collapsible furniture lid 17 has been divided into two, as mentioned above in an exemplary hypothesis, and is formed by a top folding lid piece 19 and a bottom lid folding piece 20, which are mutually joined together. mutually articulated mode by means of an axis 21 of hinges. The hinge shaft 21 is usually formed by two hinges 22 arranged respectively in one of the two lateral end areas of the furniture cover 17. The hinge 22 may have an upper hinge piece to be fixed in the upper folding lid piece 19 and a lower hinge piece to be fixed in the lower folding lid piece 20, which are mutually articulated by means of a hinge pin or the like that forms the axis 21 of the hinge. The two hinge pieces can be fixed on the inside of the pieces 19, 20 of the hinged lid directed towards the shelf of the cabinet. The axis 21 of the hinge can be arranged near the slit between the two pieces 19, 20 of the hinged lid or also at a certain distance above or below the slit.

The upper folding lid part 19 has also rotatably supported around an articulation axis 23 of the furniture body 12. This axis 23 of articulation is preferably in the roof 15 of the body 12 of the furniture.

In the closed position, the piece 20 of the lower folding lid is attached to the lower part of the upper folding lid part 19 being extended with it, so that the two folding lid pieces 19, 20 are forming the same flat. When moving to the opening position, the two pieces 19, 20 with a flip-up lid make counter-rotating movements, while the top-fold cover piece 19 rotates away from the shelf 16 of the cabinet and, with it, from the body 12 of the furniture, the lower folding lid part 20 rotates around the hinge axis 21, from its coplanar position with the upper folding lid part 19, towards the shelf 16 of the cabinet and, therefore, towards the body 12 of the furniture so that the folding lid 17 of the furniture is retracted so to speak.

In at least one of the two lateral end areas of the cabinet, a maneuvering lever 24 has been arranged, which has been stationary articulated, on the one hand, in the body 12 of the furniture by means of a rotation axis 25 and, on the other hand, in the folding lid 17 of the furniture, especially in the lower folding lid piece 20. It has been assigned to the end 26 of the lever, which gives the cabinet body, a maneuvering disc 27 as an example hypothesis.

The maneuvering disc 27 has two mutually opposite contour zones of the curve zones 28, 29 arranged in the maneuvering disc 27. The maneuvering disc 27 is dynamically coupled with the maneuvering lever 24, which means that, when turning the maneuvering lever 24, the maneuvering disc 27 also rotates in solidarity. For this, the maneuvering disc 27 has two disc portions 30, 31, which have been fixed on the maneuvering lever 24 to the right and to the left thereof, therefore, the maneuvering lever 24 is in its center . Alternatively, a one-piece operating disc can be installed alternately. The two curve zones 28, 29 have, respectively, an eccentric curve section 32, 33 and the first curve zone 28, at least one circular arc-shaped curve section 34 immediately attached thereto. According to the preferred embodiment, the second curve zone 29 also has a circular arc-shaped curve section 35. The function of the curve sections 32 to 35 will be explained in more detail below.

The first curve zone 28 is assigned a first thrust piece 37 held against the first curve zone 28 by a first elastic mechanism 36. The first elastic mechanism 36 has been articulated, on the one hand, flexibly to a hardware plate 38 installed on the side wall 13 and, on the other hand, has been flexibly joined with a first energy transmitting element 39, which, in turn, it has been rotatably supported on the hardware plate 38 again around a rotation axis 40 and which supports the first thrust piece 37. The first elastic mechanism is shown here, by way of example, in the form of a pressurized gas spring 36. It would also be possible to alternatively install a compression coil spring. The first thrust piece 37 has been made with a sheave, rotatably supported on the force transmitting element and along which the first curve zone 28 rolls. The pressurized gas spring 36 can be supported by means of adjustment elements along the energy transmitter element 39. As an adjustment element, according to DE 10 2004 019 789 A1, for example, a maneuvering spindle can be supported, which runs on the first force transmitter element 39 in the direction 41 of the regulation, and which is stationary supported in its longitudinal direction. The pressurized gas spring 36 can rest on the maneuvering spindle and fit it with thread. If the operating spindle 42 is rotated by means of a suitable tool, for example a screwdriver, the pressurized gas spring 36 is moved along the operating spindle. In this way, the lever ratios existing in the first force transmitting element 39 and, consequently, also the turning torque exerted on the operating lever 24 by the first force transmitting element 39 are modified by means of the sheave 40.

The second bend zone 29 has been assigned a second thrust piece 44 held against the second bend zone 29 by a second elastic mechanism 43. The second thrust piece 44 rests on a second energy transmitting element in the form of a pivoting lever 45, which has been rotatably supported on the hardware plate 38 about an axis 46 of rotation of the pivoting lever. The second thrust piece 44 has also been made in the form of a roller, through which the second curve zone 29 rolls by turning the maneuvering lever 24. The second elastic mechanism 43 has been fixed, on the one hand, stationary in the hardware plate 38 and, on the other, is connected with the pivoting lever 45. The second elastic mechanism 43 has been shown, by way of example, in the form of a helical traction spring 43, which pulls the pivoting lever 45 together with the second thrust piece 44 until it makes contact with the second curve zone 29. The pivoting lever 45 also has an end portion 47 protruding from the contour of the hardware plate 38, on which rests a damping mechanism in the form of a cushion cylinder 48. The damper cylinder 48 has a cylinder body 49, which has been fixed to the final part 47 of the pivoting lever 45 and which can be rotated together by rotating the pivoting lever 45. In the body 49 of the cylinder, an actuating part in the form of a maneuvering piston 50 is movable. The maneuvering piston 50 acts with a flange 51 in the form of a fingernail, configured in the hardware plate 38, such that, with the movement of insertion of the folding lid 17 of the furniture in the closed position 18, the actuation shoulder 51 comes into contact with the maneuvering piston 50 and presses it inwards in the body 49 of the cylinder, whereby the insertion movement of the hinged cover is damped.

In the closing position 18 of the folding lid 17 of the furniture, the second thrust piece 44 is in a receiving concavity 52 at the end of its eccentric curve section 33, while the first thrust piece 37 is attached to the first zone 28 of opposite curve in section 34 of circular arc-shaped curve. In this situation, basically no torque is exerted on the maneuvering lever 24 by the first thrust piece 37 by contact with its circular arc-shaped curve section 34, it could also be said that the first part 37 of push is inactive. The second thrust piece 44, on the contrary, makes a torque in the direction of the closure by contact with the eccentric curve section 33, which means that the folding lid 17 of the furniture is pressed with closing force against the body 12 of the furniture. When the folding lid 17 of the furniture is opened, then the eccentric curve section 33 of the second bend zone 29 exceeds first the second thrust piece 44, whereby a closing force is exerted on the folding lid 17 of the furniture, since in the first zone 28 of the opposite curve, the circular arc-shaped curve section 34 is still in contact with the first thrust piece 37, so that, in this case, no turning torque is introduced. The closing force will be even greater, since the lever arm - perpendicular distance between the normal by the tangent, between the thrust piece 44 and the curve section 33, and rotation axis 25 - which jointly determines the torque of turn will be greater at the beginning.

The reversal point or the neutral position has been represented in Figure 3. In this position, the second thrust piece 44 is in contact in the transition between the eccentric curve section 33 and the circular arc-shaped curve section 35. According to another example of an additional embodiment not shown, an additional eccentric curve section can be attached to the second curve zone 29 in its eccentric curve section, which is configured so that, when exceeded by the second thrust piece, exercise an additional torque on the folding lid of the furniture, which acts in the direction of the opening. Therefore, the torque, generated in the first curve zone in the direction of the opening, is reinforced by it. It is possible to set the slope of the additional eccentric curve section in the second curve zone as for a trough-shaped concavity 55. This transition between the eccentric curve and circular arc-shaped or additional eccentric curve sections 33, 35 has been shown here, by way of example, by means of a prominence 53. The second thrust piece 44 does not essentially exert torque. of any rotation on the operating lever, it is therefore inactive or exerts a torque in the direction of opening. At the same time, the first thrust piece 37 is in the first zone 28 of opposite curve in the transition between its circular arc-shaped curve section 34 and its eccentric curve zone 32. Although, in principle, it would also be possible for the first thrust piece 37 to be in contact with its eccentric curve section 32 so that, when the pressure pieces 37, 44 are exceeded, the two neutral positions are not reached simultaneously.

If the folding lid 17 of the furniture is now opened further, then it exceeds the circular arc-shaped curve section 35 or the additional eccentric curve section of the second curve zone 29 the second pressure piece 44, whereby it will be it is inactive, so to speak, and essentially no torque will be introduced or a torque will be generated in the opening direction, while, in the first zone 28 of opposite curve, the eccentric curve section 32 will exceed the first piece 37 of pressure. In this case, a torque is then introduced on the operating lever 24 and precisely in the direction of opening of the furniture folding lid 17. This turning torque acts against the weight of the folding lid so that the opening of the folding lid 17 of the furniture is facilitated. By appropriate contouring of the eccentric curve section 32 in the first curve zone 28 and, where appropriate, of the additional eccentric curve section in the second curve zone, it is also possible that the collapsible lid 17 of the furniture remains parked in a discretionary opening position. The opening movement of the folding lid 17 of the furniture is previously fixed by means of terminal stops in the form of concavities 54, 55 of the trough type, on the one hand at the end of the eccentric curve section 32 of the first curve zone 28 and, on the other, at the end of the circular arc-shaped curve section 35 or the other additional eccentric curve section of the second curve zone 29.

When closing the lid 17 of the furniture, reverse processes are developed. The eccentric curve section 32 of the first curve zone 28 exceeds the first thrust piece 37 and precisely in the reverse direction, while, in the second zone 29 of opposite curve, the circular arc-shaped curve section 35 or the Additional eccentric curve section exceeds the second pressure piece 44. As long as the first thrust piece 37 is still in contact with the associated eccentric curve section 32, a torque will still be exerted in the opening direction, since, in the second zone 29 of opposite curve, the second piece Pushing 44 will be in contact with its circular arc-shaped curve section 35 or with the second additional eccentric curve section. Then, the reversal of the torque takes place again when the neutral positions between the respective eccentric curve sections 32 to 35 and in the form of additional circular or eccentric arcs are exceeded. From here, the first thrust piece 37 is again in contact with its circular arc-shaped curve section 34, while the second thrust piece is in contact with its eccentric curve section 33 so that a torque in the direction of closure.

In general, it can be established that at least two energy accumulators 28, 36, 37, 29, 43, 44 of energy, which act mutually independently, are assigned to the end zone of the maneuvering lever 24 on the side of the furniture body. , of which an energy accumulator 28, 36, 37 preferably reinforces the opening movement of the folding lid 17 of the furniture and does not exert in a turning area from the closed position to a neutral position almost no turning torque , while the other energy accumulator 29, 43, 44 exerts, above all, a closing force in the turning area from the closed position to the neutral position.
