Description

The invention relates to a holding element according to the preamble of claim 1.

Such a holding element is z. B. from the DE 102 23 026 B3 known. The holding element has an actuating arm, which can be pivotally mounted on a side wall of a cabinet body. On the actuating arm, a control contour is arranged with a variable distance from the pivot axis, against which a spring-loaded lock slider is acted upon. By means of the adjusting contour of the actuating arm is applied starting from an intermediate position between an open position and a closed position of the actuating arm with force in the direction of the open position. From the intermediate position to the closed position of the actuating arm is acted upon by a force in the direction of the closed position. This makes it possible that the lid between the intermediate position and the open position is held in any position.

US Pat. No. 7,021,728 B2 discloses a hinge assembly for a monitor of an overhead entertainment system, especially for vehicles. In a closed position or storage position, the monitor is in an at least approximately horizontal position. From this storage position, the monitor can be moved to an open position in which he down z. B. is pivoted in a vertical position. In the storage position, the monitor is held in this position via a pawl or latch. After the final locking, the monitor is transferred to an intermediate position. Here, spring means are provided which bias the monitor and pressurize until reaching the intermediate position with force. After reaching the intermediate position, the monitor can be moved further in the direction of the open position, wherein only one friction force of a friction arrangement must be overcome. The spring is not effective starting from the intermediate position to the open position.

Object of the present invention is to provide a simply constructed holding element that allows a part of the pivoting path of the actuator arm an independent adjustment of the actuator arm.

The object is achieved by a holding element according to claim 1.

Thus, it is ensured that the actuating arm, starting from the closed position to the intermediate position by means of the spring means is acted upon by force and can be converted from these to the intermediate position. From then on in the direction of the open position, a freewheel is thus ensured, which allows an approximately powerless adjustment of the actuating arm. An advantage of this arrangement is that the holding element is suitable for so-called push-push closures, in which the lid is held in the closed position by means of a lock. To release the lid can be moved in the same direction as in the movement from the intermediate position to the closed position, wherein the lid is moved beyond the closed position. In this position, the lock is released, so that the spring means can then transfer the actuator arm and thus the lid from the closed position to the intermediate position. Starting from the intermediate position of the actuator arm and thus the lid can be moved manually to the open position without force to overcome a spring force, with further locking means may be provided which hold the lid or the cover plate in the open position.

Characterized in that the spring means are supported via a pivoting of the actuating arm from the intermediate position to the open position against a stop and thus enable a freewheeling of the actuating arm is ensured in a simple manner that the spring means after passing through the pivoting path of the actuating arm from the closed position to the intermediate position do not make any further travel and thus do not continue to apply force to the actuator arm.

To act on the actuating arm, the spring means are supported in a first circumferential direction against a support surface provided on the actuating arm. However, this support takes place only when the actuator arm between the closed position and the intermediate position is located. In all other positions of the actuator arm, the spring means are not supported against the actuator arm or the support surface.

In order to ensure the clearance of the actuating arm between the intermediate position and the open position is provided that the spring means are supported in the first circumferential direction against a stop of the base member when the actuator arm is between the intermediate position and the open position.

Preferably, the spring means comprise a coil spring or a leg spring or the spring means are designed as such. Coil springs and torsion springs have the advantage that they have a small space and even in deformation, d. H. when passing through a predetermined spring travel, have only a slight change in the outer dimensions. In contrast to compression springs thus the space of the entire holding element can be significantly reduced.

The base member may in this context have a cylindrical spigot around which the spring means, preferably in the form of the aforementioned coil spring or leg spring, are arranged. The cylindrical spigot serves to receive the spring means and to guide the same. Furthermore, the actuating arm can be pivotally mounted on the spigot.

The spring means may be secured with a first end in a mounting receptacle of the base member. For this purpose, the coil spring or the leg spring may have a leg which engages in a fastening receptacle in the form of a bore.

In order to be able to vary the pretensioning of the spring means, it can be provided that a plurality of fastening receptacles arranged over a circumference about the first pivot axis are provided, in which the spring means can be optionally secured.

For connection of the holding element with a lid, a fitting part may be provided which can be fastened to the lid. The actuator arm is at its first Pivot axis facing away from the fitting part pivotally mounted about a first lid axis.

Further, for a defined movement of the lid, a control arm may be provided which is pivotally mounted on the base member about a second pivot axis arranged parallel to the first pivot axis. In this case, the control arm is further fastened to the fitting part so as to be pivotable about a second cover axis arranged parallel to the first cover axis.

It has been found that a particularly good sequence of movements results when a first force action line from the first pivot axis to the first cover axis and a second force action line from the second pivot axis to the second cover axis intersect in the open position of the actuating arm. Here, the two force lines of action intersect between the cover axes and the pivot axes. In the closed position and also in the intermediate position of the actuating arm, the force action lines are arranged at an angle to each other and do not intersect between the pivot axes and the cover axes. Rather, the force action lines intersect in their extension over the pivot axes and / or cover axes.

FIG. 1 shows an exploded view of a first embodiment of an end according to the invention holding element with a base member 1, which can be attached to a side wall of a container, in particular a furniture body, attached. On the base arm 1, a control arm 2 is pivotally mounted about a pivot axis S1 between a closed position and an open position. Spring means 3 in the form of a leg spring serve to force the actuating arm 2 above a portion of the pivoting path from the closed position to an intermediate position, which is located between the closed position and the open position, with force.

The base element 1 has fastening bores 4, 5, via which the base element 1 can be fastened to the furniture body by means of fastening screws (not illustrated here). Coaxial with the first pivot axis S1 is a centering lug 6 on Base element 1 is provided, which is designed substantially cylindrical and has a first centering section 7 and a second centering section 9. The first centering portion 7 forms a first centering surface 8 in the form of an outer peripheral surface, around which the spring means 3 are arranged, wherein between the first centering surface 8 and the spring center 3 a radial clearance is provided (s. FIG. 3 ), so that the inner diameter of the spring means 3 can be reduced in a force application and deformation. The first centering surface 8 is used in particular to secure the spring means 3 against tilting.

The second centering section 9 forms a second centering surface 10 in the form of an inner peripheral surface. On the second centering 9 of the actuating arm 2 is attached, wherein the actuating arm 2 has a central coaxial with the first pivot axis S1 extending approach 11 with an outer peripheral surface 12. In the assembled state, the outer peripheral surface 12 is in contact with the second centering surface 10 in order to center the actuating arm 2 and to hold it rotatably on the base element 1. For this purpose further serves a shaft extension 13 on the spigot 6, which projects coaxially to the first pivot axis S1 and is guided through a central bore 14 of the actuating arm 2. The free end protrudes on the side facing away from the centering shoulder 6 of the steep arm 2 out of the central bore 14, wherein a locking ring 23 is attached to the free end and the actuator arm 2 fixed.

The actuating arm 2 has a wall 15 which revolves around the first pivot axis S1 and which forms a cap with a side wall 20 of the actuating arm 2 which covers the centering shoulder 6. The wall 15 is here u. a. arranged around the spring means 3 to protect them from external influences.

In a circumferential annular portion 24, which protrudes radially from the centering 6, are circumferentially distributed a plurality of fastening receptacles 17 in the form of holes which extend parallel to the first pivot axis S1 arranged. The spring means 3 have a first end 16 in the form of a leg, which runs parallel to the first pivot axis S1 and is inserted into one of the fastening receptacles 17. Further, the spring means 3, a second end 25, also in the form of a leg, which is also parallel to the first pivot axis S1. By Twisting the two ends 16, 25 to each other, the spring means 3 can be braced. In a preassembled condition according to FIG. 2 the two ends 16, 25 are rotated in a clockwise direction relative to each other. At the centering projection 6, a cam 18 is provided which projects radially from the centering projection 6 and forms a stop with a stop surface 19. Im in FIG. 2 illustrated preassembled state, the second end 25 is supported in the circumferential direction against the stop surface 19, so that the spring means 3 are held in the prestressed state. In order to vary the bias, the first end 16 of the spring means 3 is inserted into another mounting receptacle 17. In order to simply bias the spring means 3, the cam 18 has a ramp surface 22, which approaches in the circumferential direction, starting from the stop surface 19 of the first pivot axis S1. Thus, z. Example, by means of a tool, the second end 25 of the spring means 3 are rotated clockwise, the second end 25, the ramp surface 22 slides along and is moved radially outward until the second end 25 engages behind the cam 18 and is supported against the stop surface 19 ,

On the side of the side wall 20 of the actuating arm 3 facing the centering shoulder 6, a support surface 21 is formed, which extends approximately radially and, viewed in the circumferential direction, points in the same direction as the stop surface 19. In the intermediate position of the actuating arm 2, the support surface 21 is against the second end 25 of the spring means 3 supported, wherein the second end 25 is still in contact with the stop surface 19. When turning the actuator arm 2 clockwise, the second end 25 is pressed clockwise so that the second end 25 lifts from the stop surface 19 of the cam 18 and the spring means 3 are further biased. The spring means 3 can then adjust the actuating arm 2 on the support surface 21 back to the intermediate position counterclockwise, wherein from reaching the intermediate position in which the second end 25 abuts against the stop surface 19, the actuating arm 2 are further rotated freely counterclockwise can.

The holding element further comprises a fitting part 26 which can be mounted on a lid of the container or the piece of furniture. On the fitting part 26, a shaft extension 27 is provided, on which the actuating arm 2 is attached at a free end 30 with a bore 28 and thus pivotable about a first cover axis D1 is connected to the fitting part 26. Further, the holding member comprises a control arm 29 which is pivotally mounted about a second pivot axis S2 on the base member 1 and is pivotally mounted on the fitting part 26 about a second lid axis D2. Here, all the Schenk axes S1, S2, D1, D2 are arranged parallel to and spaced from each other.

Based on FIGS. 5 to 10 The movement sequence of the holding element in a piece of furniture is shown below. The FIGS. 5 to 10 will be described together below. The piece of furniture comprises a body, of which the side wall 31 and a top floor 32 are shown. On the side wall 31, the base element 1 of the holding element is mounted. The body is closed by a cover 33, which is held by means of the holding element pivotally relative to the body. Here, the lid 33 is not connected via separate hinges with the body but mounted only on the holding element pivotally mounted on the body. In principle, however, there are also other applications. The use of the holding element according to the invention is not limited to the application shown here.

In the in the FIGS. 5 and 6 shown closed position of the actuating arm 2, the spring means 3 are biased, wherein the second end 25 of the spring means 3 are supported against the support surface 21 and are lifted from the stop surface 19. The spring means 3 act on the actuating arm 2 via the second end 25 in the counterclockwise direction in the FIGS. 7 and 8 illustrated intermediate position. Thus, the actuator arm 2 is held in the closed position and thus the lid 33 remains in its closed position, a detent 34 is provided, which may for example be attached to the side wall 31 and holds the lid 33 in the closed position. This is preferably a lock, which allows the so-called push-push function, in which the cover 33 is pressed beyond the closed position further in the direction of the body, whereupon the lock 34 is released. After releasing the lock 34, the actuator arm 2 of the closed position in the in FIGS. 7 and 8 shown intermediate position überfuhrt.

In FIG. 4 It can be seen that a first wall 35 forms the support surface 21. The first wall 35 extends radially with respect to the first pivot axis S1 and protrudes over a certain height from the side wall 20 of the actuating arm 2 in the direction of the centering projection 6. Further, a second wall 36 is provided, which is viewed in the direction of transition offset from the first wall 35 is arranged and also extends radially. The two walls 35, 36 pass into the extending about the pivot axis S1 wall 15 of the actuating arm 20 and are connected to each other via a wall 15 spaced inner wall 37 connected to each other, so that between the walls 15, 35, 36, 37, a groove 38th is formed, in which the second end 25 of the spring means 3 relative to the actuating arm 2 is movable and guided. The walls 35, 36, 36 can all protrude over the same height from the side wall 20 of the actuating arm 2, so that the second end 25 of the spring means 3 can also be supported against the second wall 36. It can also be provided that the wall 36 protrudes from the side wall 20 at a lower height, wherein the second end 25 can pass the second wall 36 when the actuating arm 2 pivots relative to the second end 25. The relative movement of the second end 25 to the actuating arm 2 is thus not limited. In addition, it may be provided that the walls 36, 37 are omitted and only the first wall 35 is provided. However, the groove 38 is preferably provided to provide guidance of the spring means 3, particularly the second end 25.

In the in the FIGS. 7 and 8 shown intermediate positions, the second end 25 of the spring means 3 is supported against the stop surface 19 of the cam 18 and no longer acts on the actuating arm 2. Rather, from now on, the actuator arm 2 can be further adjusted counterclockwise without a force support takes place by the spring means 3. Furthermore, no spring force on further pivoting of the actuating arm 2 to overcome, since the second end 25 can adjust freely within the groove 38. Thus, the lid 33 of the in FIG. 7 shown intermediate position further upward in the open position according to Figures 9 be transferred, the actuating arm 2 reaches its open position. In this position, not shown locking means may be provided which hold the lid 33 in the open position.

In the open position, a first force action line K1 from the first pivot axis S1 to the first lid axis D1 and a second force action line K2 from the second pivot axis S2 to the second axis of rotation D2 are arranged to each other such that they intersect. The Kraftwirkungsfinien K1, K2 are defined here as the shortest paths distances between the respective pivot axis S1, S2 and the respective cover axis D1, D2. The force action lines K1, K2 thus intersect between the pivot axes S1, S2 and the cover axes D1, D2. In the open position according to FIG. 5 the force action lines K1, K2 are arranged at an angle to each other so that they intersect in their extensions beyond the cover axes D1, D2. That is, the force action lines K1, K2 defined as infinite-length paths do not intersect, but rather lines of infinite length that pass through the force action line K1, K2.

The FIG. 11 shows a second embodiment of a holding element according to the invention, wherein components which are identical to components of the first embodiment, are provided with the same reference numerals.

In contrast to the first embodiment, the centering projection 6 only has a first centering section 7 for receiving the spring means 3. The actuator arm 2 is connected only to the base element 1 via a fixing element 42. Furthermore, not the centering projection 6 but a separate disc 39, the cam 18. The disc 39 is connected to the front side of the spigot 6. To prevent rotation, the disc 39 has three projections 40 facing the centering projection 6, which engage in the mounted state in end-side recesses 41 of the centering projection 6. For mounting and biasing the spring means 3, the disc 39 is initially aligned with the spring means such that the stop surface 19 of the cam 18 is in abutment with the second end 25 of the spring means 3. Then, the disc 39 is rotated clockwise, wherein the spring means 3 are biased. The projections 40 are aligned with the recesses 41 so that the projections 40 can engage in the recesses 41 when the disc 39 is in an angular position to the spigot 6, in which the spring means 3 are biased.
