Definitions

  • the invention relates to a device for opening or lifting one on a hinge with horizontal pivot axis downwards hanging door according to the preamble of Claim 1. Furthermore, the invention relates to a door with such a device.
  • Furniture systems are designed to meet a wide variety of needs (spatial, user-technical etc.) can be adapted.
  • Cabinet elements should e.g. mounted as needed not only in low to medium, but also at a greater height can be, with the cabinet door should be easily operable.
  • swing doors are beneficial to one rotatably mounted on the upper edge of the element arranged pivot axis are. That is, when closed, the door hangs substantially vertically below so that it must be swung open to open. So that the door on the one hand can be opened without great effort and on the other hand in the open Position can remain without the help of the user, a door lift is installed.
  • Scissor hinges and hinges that are operated or supported by springs are already known in large numbers. But they are not designed for doors that are on an overhead Hinge are suspended and from a substantially vertical to an in essential horizontal position to be pivoted.
  • the gas cylinder is inferior to a steel spring. Not only the average life of a gas cylinder is much shorter than that a steel spring, but it is also the disposal consuming.
  • US 4,516,813 shows a hinge for a downwards hanging in the closed state and in the open state horizontally projecting door flap, which also retractable is executed.
  • the angle lever which supports the door is not rotatable about a fixed mechanical axis, but is characterized by two short Swivel arms in the room moved and rotated.
  • a leaf spring is provided, which is more or less parallel beside the two short ones Swivel arms runs and attacks directly at the end of the door supporting the angle lever.
  • DE-OS 2 106 614 shows a toggle hinge in which the door supporting Arm at the rear end a sliding guide with a shorter and a longer curved path having.
  • the end of a spring-supported arm is slidable stored.
  • the spring-loaded arm jumps from one set of scenes to the other.
  • DE 2 151 935 A shows a mechanism for a trunk lid or a Luggage compartment door of a bus.
  • the door is through a toggle with a long and a short leg. On the long leg one engages the vehicle supported spring so that the weight of the door when lifting from the vertical hanging in the horizontal projecting position is compensated.
  • the object of the invention is to provide a device of the type mentioned, which on the one hand avoids the disadvantages of the known door lifter and on the other hand not only has an adequate force development (so that the door does not open in an uncontrolled manner) or can strike), but is also compact in construction.
  • the construction of the door lifter is characterized by a toggle mechanism off, which with the door closed in the area of its dead center and opened Door is in its power transmission maximum.
  • a drive or force element is a spring (e.g., a coil spring).
  • the knee lever ensures a metered transmission of the spring force.
  • the spring is tensioned, prevents the located in or near dead center knee lever but that the power can unfold.
  • you open the door comes the Knee lever after a short movement from the dead center and acts with increasing Opening angle with greater torque.
  • the leverages can be so specify that the torque exerted by the door lifter is only slightly larger than that opposite torque of the door is. In the course of a 90 ° pivoting movement can the door is therefore not at a high speed (even if left to itself) be accelerated.
  • the mechanism is designed so that the a leg of the toggle lever is formed on a lever element, which is the door to Open contacted.
  • the lever element is rotatably mounted in a point which a has a certain distance from the pivot axis of the door.
  • the second leg of the toggle lever is with its free (rear) end to a one-armed Guide lever articulated. That a four-bar linkage is formed, one of them Corner against the inside (in the area of the toggle dead center) can bend.
  • the toggle mechanism actuating compression spring sets according to a particularly preferred embodiment on the guide lever. But it is also conceivable that the spring engages at a different location on the toggle mechanism. In particular, it could start directly on the second leg or in an extension be arranged.
  • the first leg of the bell crank is e.g. shorter than the second. This can reduce the burden of the door hinge (which is supported by the distance of the door lifter supported by the door lift Point of the door of the axis of the hinge is determined) can be reduced.
  • the ratio of the effective lengths is about 2: 3.
  • you can the leverage ratios are varied to the power transfer to the variable torque adapted, which is generated by the weight of the door and the Opening angle depends.
  • toggle mechanism and the compression spring in a narrow, rectangular flat frame are housed.
  • This frame is e.g. divided by two stamped sheets formed, which are interconnected by short spacers are.
  • the frame is symmetrical.
  • the door lift device is then independent of page, i. It can be mounted either left or right of the door.
  • the moving parts of the mechanism can also be on one side open frame or directly attached to a wall element.
  • the device does not need to be completely symmetrical in design.
  • the structure is but chosen so that it is at least functionally independent of pages.
  • the compression spring should always be within the frame so that it does not move during the opening or closing movement obstructed or blocked by randomly approaching objects can be. Only the actuator arm, which contacts the door, should from the Protruding flat frame.
  • the knee lever is about to be reached the closing position beyond the dead center. So that the knee joint of the toggle lever with the door closed, i. in the area beyond the dead center, a defined position occupies and not uncontrollably kinked, a stop element may be provided. This may be e.g. to act on a plastic element that is in place in the Flat frame is integrated.
  • a lock should ensure that the door has a defined Takes position.
  • This locking is preferably also on the frame of the Door lifter and engages, for example, on the second leg of the toggle lever.
  • Another possibility is e.g. therein, in the coil spring, a stroke limitation provided.
  • the inventive door lifter is particularly suitable for cabinet elements, which on elevated place are placed.
  • the door is e.g. suspended on a separate pivot bearing and is opened by the door lifter.
  • the pivot axis of the door is then normally not coincide with the fulcrum of the lever pushing on the door, but have a certain eccentricity relative to the fulcrum. So this eccentricity does not hinder the opening and closing movement, e.g. a sliding contact be provided between door lift and door.
  • the door lifter (and thus the Fulcrum of the operating lever in question) stationary, the pivot axis of the door, however displaceable.
  • the pivot bearing of the door is on a horizontally movable carriage stored so that the whole door after opening in the cabinet element (or a corresponding provided shaft) can be sunk.
  • the retractable door has e.g. a coupling piece, in which a corresponding Engage piece of the operating lever during the opening and closing movement can.
  • the coupling is designed so that the pieces when sinking the door without Solve effort from each other.
  • the coupling between the door lift and the door makes it possible to pull the door when closing in the desired closed position. That it can not only pressure, but also train to be transferred.
  • the trained on the door lifter coupling piece provides the coupling piece of the door preferably a stop so that the door when opening just before reaching the horizontal protruding position necessarily retracted by a certain amount in the cabinet element becomes. In this slightly lowered position, the door is against an undesirable Overspeeding better secured ('' crash protection '').
  • Fig. 1 a particularly preferred embodiment of the invention is shown.
  • the moving parts are housed in a frame, which essentially by two side parts 1, 2 is formed.
  • Fig. 1 only the side part 1 is shown.
  • the second (which can be seen in Fig. 2b) has been omitted to the toggle mechanism to make visible.
  • the side parts 1, 2 are configured identically. It is elongated, rectangular, flat sheet steel elements, which are not relevant in the areas of stability excluded (e.g., stamped out). The height is e.g. only about 1/5 to 1/6 the length.
  • the two side parts 1, 2 at a desired distance connects to each other and on the other hand rotatably supports an L-shaped operating lever 3.
  • the door lifter i.e., open, horizontally protruding Door
  • At its end is one Coupling piece 20 attached.
  • the short leg 3.2 closes with the long one Angle of slightly less than 90 °. It protrudes in the open position according to FIG. 1 below. Its length corresponds approximately to the height of the frame.
  • clevis 13 of a rod 12 at.
  • the Connection between clevis 13 and guide lever 8 is articulated (axis 11).
  • the rod 12 is slidably mounted with its rear end in a tube 14.
  • the tube 14 itself is pivotally mounted on the axle 15.
  • a coil spring 21 which the clevis 13 (and thus the rod 12) forward, i. out of the tube 14 pushes.
  • two stop elements 16.1, 16.2 extend. It can be e.g. to act strip-shaped parts made of plastic.
  • FIG. 1 is a cam 17 located, which in a manner to be described as a stop element serves.
  • a second, similar cam is formed on the flat element 5.2.
  • the aforementioned stop elements are on the outer sides of the flat elements 5.1, 5.2 (i.e., on the surfaces facing the side parts 1, 2 of the flat elements).
  • On the inner sides of the side parts 1, 2 are corresponding at corresponding location Stop elements (not shown) arranged. In the open position of the Door lifters ensure that the stop elements mentioned that the operating lever. 3 occupies a defined position.
  • the two side parts 1, 2 are not only by the axes 4, 10, 15, but also by the spacers 18, 19 connected to each other. It therefore exists at least in three Corners of the frame a connection between the side parts 1, 2.
  • Fig. 2b is clearly the symmetry of the inventive construction with respect to Frame center plane (i.e., parallel to the planar side parts 1, 2 and in the Center to this standing geometric plane).
  • the mutual distance the side parts 1, 2 is chosen as small as possible.
  • Fig. 2b corresponds to the mentioned Distance of the sum of the thickness of the following elements: operating lever 3, Flat elements 5.1 and 5.2, stop elements 16.1 and 15.2.
  • FIG. 1 the door lifter is shown in FIG. 1, as exemplified in a cabinet element is mounted.
  • the front side part 2 is again omitted, to release the view of the toggle mechanism.
  • a door 22 is suspended on a hinge 23 with a horizontal axis of rotation.
  • the axis of rotation is perpendicular to the plane of the drawing.
  • the Door 22 may extend from a vertically suspended ( Figure 3b) to a horizontally projecting ( Figure 3a). Be pivoted position.
  • the plate-shaped door 22 is on the upper edge 22.1 connected to the hinge 23.
  • the hinge 23 is seated on a carriage 24, which in the direction of arrow 29 on a Rail 25 can be moved back into the cabinet element into it.

  • Fig. 3a, b is hinted a frame tube 27 shown which is part of the cabinet element and which is the upper edge of the cabinet opening forms. (Other, not shown frame tubes limit said opening to the three remaining edges.)
  • a coupling piece 26 is mounted, which in the Coupling piece 20 of the door lifter can intervene.
  • the power transmission ratio of the toggle lever With decreasing opening angle, the power transmission ratio of the toggle lever lower.
  • the coil spring 21 increases the pressure during compression, takes a total of the force applied by the operating lever 3 on the door 22 force.
  • These Decrease in force corresponds to the torque, which is due to its own weight the door 22 (based on the axis of the hinge 23) is generated and which with decreasing Opening angle is lower.
  • the user has the feeling that the door 22 is balanced.
  • the lever ratios in the door lifter be chosen so that the door has a tendency to open or closed To move position.
  • Fig. 3b shows the closed position.

  • the joint is beyond the dead center, resulting in has that the pressure of the coil spring 21 no longer pushes the door to the outside, but moves inwards into the closed position.
  • the closing of the door 22 by the coupling pieces 20 and 26 allows becomes.
  • the dead point is e.g. passed through at an opening angle of 5 ° to 10 °, i. at an angle at which the conditional by the weight of the door torque is relatively small.
  • the door is already a minimal Torque exerts on the lever mechanism and the incipient force development of the Spring thereby brakes.
  • the flat elements 5.1, 5.2 lie with the door lifter closed substantially parallel to the guide lever 8.
  • the rod 12 and the guide lever 8 enclose an angle close to 180 °.
  • An imaginary extension of the rod 12 passes essentially through the axis 4.
  • the axis 10 is thus slightly above an imaginary connecting line between axis 11 and axis 4. Looking at this formed by the axes 4, 7 and 6 triangle and compares it with that through the axes 10, 11 and 15 formed triangle, then it is found that these are directed towards each other are.
  • the base is 4/7 opposite corner (6) on the triangle 10/11/15 facing side.
  • In analogous Way is located at the triangle 10/11/15 of the base 10/15 opposite Corner (11) on the side facing the triangle 4/7/6.
  • Fig. 3a From Fig. 3a is further seen that the length of the flat elements 5.1, 5.2 (or the distance between the axes 6, 7) is slightly smaller (e.g., about 10%) smaller than the mutual one Distance of the axes 4 and 10. In addition, the distance between the axes 6 and 11 in the open Position of the door lift slightly (for example, about 10%) greater than the mutual distance of Axles 4 and 10.
  • the coupling pieces 20, 26 may e.g. according to the tongue and groove principle in the direction of Arrows 29 (i.e., parallel to the door) are telescoped.
  • the door 22 is already slightly sunk when reaching the open position. That the axis of Hinge 23 is no longer at the same door with the door open 22 as when the door is closed 22. Rather, it is shifted in the direction of arrow 29 to the rear.
  • the door 22 in fact stands on the frame tube 27 and consequently can not on the horizontal Be pivoted position out to the top. The resulting blocking is all the more more reliable, the farther the contact point between door 22 and frame tube 27 from the axis of the hinge 23 is.
  • the pushing back of the door 22 is related to the fact that on the one hand a distance between the axis 4 of the actuating lever 3 and the axis of the hinge 23 is and on the other hand that the coupling pieces 20, 26 are formed so that the door 22 when panning can not move beyond a position, which by the Geometry with the door closed 22 is determined.
  • the door does not need to be retractable. It is quite possible that she is stuck with is connected to the operating lever of the door lifter. Swivel axis of the door is then the Axle of the operating lever. It can also be a fixed, independent from the door lift Hinge are assumed, in which case the contact point between the operating lever and door can move.
  • the toggle may be designed to be straight in the closed position located in the dead center. But it is by no means impossible that the dead center even is not achieved. That the spring will then always exert an opening pressure on the door can. To still be able to hold the door in the closed position, can be provided on the cabinet element a latching closure.
  • the embodiment shows a construction which is characterized by a low height. For other applications it may u.U. be desired to use a door lift as possible to have a small installation depth. It is easy to see that the construction shown can be rotated approximately 90 ° in the vertical, then the operating lever must be executed differently.
  • an L-shaped lever could be a one-armed Lever be provided (i.e., the leg 3.2 also serves as a contact element for Door).
  • the pivot axis of the door does not necessarily have to be provided at the upper edge of the door leaf be.
  • the door can easily be mounted upwardly projecting.
  • the invention can be used wherever it comes, a door from a bring vertical hanging position in a more or less horizontally protruding.
  • the inventive door lifter made of robust and durable elements and is built because of its compact design namely for cabinet elements with fittings (rails for pull-out drawers, intermediate shelves etc.) is suitable.
