Description

Technical Field

[0001] The present invention relates to a pull-out guide having a fixed track and a track movable relative to the fixed track, wherein a means for acceleration or deceleration is disposed on the fixed track, the means having a movable actuator that can be coupled to an actuator fixed on the movable track. Background Technology

[0002] DE 10 2010 016 179 A1 discloses a pull-out guide having a fixed guide rail and a movable running track, the pull-out guide being movable to a closed position by a self-closing mechanism. The self-closing mechanism includes an actuator movable along a curved guide integrally formed on the guide rail. An actuator is welded to the guide rail and engages with the actuator to allow the guide rail to retract to the closed position over a predetermined distance. Precise positioning and fixation of the actuator to the running track requires additional assembly steps; furthermore, tolerances may exist in the positioning along the longitudinal direction of the running track. Additionally, pushing elements, such as drawers, must be aligned on the running track via other stops or retaining devices. Summary of the Invention

[0003] Therefore, the object of the present invention is to provide a pull-out guide that is simple to manufacture and allows for convenient positioning of the push element.

[0004] This objective is achieved by pulling out a guide according to some embodiments of the present invention.

[0005] In the pull-out guide according to the invention, the actuator is integrally formed with the movable track and can be coupled to a movable actuator of the device for accelerating or braking the movable track. This eliminates the need to manufacture the actuator as a separate component and position and secure it to the movable track. Furthermore, a stop is integrally formed with the movable track and protrudes perpendicular to the longitudinal direction of the movable track for a push element that can be mounted on the movable track. Alignment of the push element and transmission of force can be achieved via the stop. This simplifies the assembly and operation of the push element. Due to the integrated design of the stop, it can be precisely positioned at the desired location on the movable track.

[0006] Preferably, in the assembly position of the pull-out guide, a recess is provided in the vertical wall of the movable track, the material of which is used to manufacture the actuator and stop by stamping and bending. At this point, a single recess can be used to manufacture the actuator and stop, such that they are integrally formed as a coherent unit projecting from the movable track. At this point, in the assembly position of the pull-out guide, the actuator may include at least one downwardly projecting protrusion, preferably two spaced-apart downwardly projecting protrusions, which engage an upwardly opening receptacle on the actuator. Preferably, at least one downwardly projecting protrusion is rounded to prevent the risk of injury and possible damage to the actuator. The actuator can then be easily coupled to the actuator to accelerate or decelerate the movable track over a predetermined distance. Different orientations of the actuator, rather than downward, can also be achieved.

[0007] In one embodiment, the stop is integrally formed with the web, which is horizontally oriented in the installation position of the pull-out guide. This web can serve as a support surface. The stop is preferably bent from the web, particularly at a right angle. The integral web can preferably be used for other functions, such as as a disengagement safety device for the push element or as a height adjustment device for the push element. Height adjustment can be achieved, for example, by a spindle, wedge slider, or similar functional element.

[0008] In another embodiment, the stop and the actuator may be directly adjacent to each other or integrally formed.

[0009] Preferably, the curved guide for the drive is integrally formed with the fixed track. In this case, the drive can engage with one or two guide elements via the grooved curved guide and engage behind the edge, for example, via a mushroom-shaped design of the guide element.

[0010] Alternatively, the device for accelerating or decelerating the movable track can be designed as a self-retracting device or a pop-out device, particularly as a push-open fitting that pops the push element out in the opening direction when the push element is pressed into the overpressed position.

[0011] In yet another embodiment, the actuator is movable between an end position and a parking position, and is biased to the end position by the accumulator. When the accumulator is tensioned, the actuator can be placed in the parking position, particularly in the inclined end section of the bending guide. In this case, the actuator can be connected to the accumulator and also additionally to a damper unit, such that the damper unit brakes the movement when the actuator moves to the end position. The damper unit can be mounted on a fixed track, for example, via an integrally formed retainer.

[0012] In addition to the embodiments shown, units for braking or accelerating movable tracks can also be attached to fixed tracks in a separate housing.

[0013] Preferably, the pull-out guide is used in furniture or household appliances, wherein the push element is movably held on the furniture body. In this case, the push element may be designed as a drawer. Attached Figure Description

[0014] The invention will now be explained in more detail with reference to the accompanying drawings and examples of embodiments:

[0015] Figure 1 A perspective view of the pull-out guide according to the present invention is shown;

[0016] Figures 2A to 2C It shows Figure 1 Multiple views of the movable track of the extended guide;

[0017] Figure 3A and Figure 3B It shows Figure 1 Two views of the movable track, and

[0018] Figure 4A and Figure 4B This shows the actuator connected to the driver. Figure 1 The two views of the extended guide. Detailed Implementation

[0019] The pull-out guide 1 for furniture or household appliances includes a fixed track 2 and a movable track 3. The fixed track can be fixed to, for example, the body of the furniture, and the movable track is held on the fixed track 2 by a rolling element. Optionally, at least one extended intermediate track can be provided between the fixed track 2 and the movable track 3.

[0020] The fixed track 2 includes an integrally formed curved guide 4, which is formed by a slot having a straight portion 7 and an inclined end portion 6. On the curved guide 4, a drive 5 is movable between an end position and a parking position on the inclined end portion 6. At the inclined end portion 6, a connection is formed with an assembly opening 8, through which the drive 5 can be inserted into the curved guide 4.

[0021] The actuator 5 is preloaded to its end position via the accumulator 9, particularly via a spring. One end of the accumulator 9 is thus fixed to a retainer 10 on the fixed rail 2 and mounted on the actuator 5 on the opposite side. Furthermore, a damper unit 11 is disposed on the actuator 5, particularly a linear damper having a damper housing and a linearly movable piston rod. The damper unit 11 is connected to the actuator 5 and is capable of braking the movement of the actuator 5 to its end position. In the illustrated embodiment, the actuator 5 is part of a self-retracting device comprising the accumulator 9 and the damper unit 11. The actuator 5 can also be provided as part of a pop-out device, such that the accumulator operates in the opening direction rather than the closing direction. Alternatively, the damper unit 11 can be omitted.

[0022] Hook 12 is provided at one end of the movable track 3 for securing a push element, such as a drawer.

[0023] exist Figures 2A to 2C The movable track 3 is shown in detail. The actuator 13 is integrally formed with the movable track 3, which is preferably made of stamped and bent sheet metal. The actuator 13 includes two spaced-apart protrusions that insert into an upwardly opening receptacle on the actuator 5. In the assembled position, the actuator 13 protrudes downwards. Preferably, the protrusions are rounded to avoid the risk of injury and possible damage to the actuator 5.

[0024] The movable track 3 is also integrally formed with the horizontal web 14, and a curved stop 15 is provided at the end of the horizontal web. The stop 15 is vertically aligned in the installation position and serves as a stop for the pushing element, which can be installed between the stop 15 and the hook 12.

[0025] A recess 16 is formed in the vertical wall of the movable track 3, and the material of the recess has been used to manufacture the actuator 13, the web 14, and the stop 15. Therefore, a single opening is formed only through the recess 16 to produce the unit comprising the actuator 13 and the stop 15. As a result, the positioning of the stop 15 and the actuator 13 is predetermined and can be precisely adjusted through the manufacturing process.

[0026] like Figure 3A and Figure 3B As shown, the portions of actuator 13, web plate 14 and stop 15 are substantially perpendicular to each other.

[0027] Figure 4A and Figure 4BAn actuator engaged with driver 5 is shown, which is movable along curved guide 4. Actuator 13 engages from above with an upwardly opening receptacle on driver 5. A horizontally projecting web 14 is adjacent to actuator 13, and a bending stop 15 is provided on the web. Driver 5 is connected to piston rod 17 of damper unit 11, enabling braking of the closing movement of movable track 3.

[0028] In the illustrated embodiment, the cross-section of the movable track is substantially cubic, and particularly nearly square. An integrated design of actuators and stops can also be provided in movable tracks 3 with different cross-sectional geometries.
