Definitions
- the invention relates to a drawer puller comprising: a carcass rail having a mounting portion for attachment to a furniture body, a drawer rail to be fastened to a drawer, which is movably mounted relative to the carcass rail, a center rail, which is movably mounted between the carcass rail and the drawer rail the middle rail has a side web facing the fastening section.
- Drawer pull-out devices of a similar type already belong to the prior art.
- the problem may exist that the rolling elements are loaded by the permanently acting forces, such as the weight of a filled drawer, and as a result the rolling elements can be deformed.
- the force on the rolling elements can be even higher than during the extraction of the drawer.
- Object of the present invention is to provide a drawer puller of the type mentioned above with a design that realizes a relief of the rolling elements as soon as it moves into the drawer in its closed end position.
- Typical drawer pull-out devices which have an inner roller arranged at a front end region of the middle rail or drawer rail.
- This inner roller is provided so that the drawer rail or the associated drawer is supported in the closed state.
- the rolling elements for example, as a load-transmitting rollers molded, which are movably mounted between the rails for transmitting the load of the drawer, relieved of the weight of the drawer and thus protected from deformation.
- this inner roller causes the drawer to be lifted slightly in the closed state and prevents undesired lowering of the drawer.
- the horizontally extending joints between the front panels of superimposed drawers of a cabinet can have a constant width, so that the visible from the outside joint image is also visually appealing.
- a support roller to be mounted on the middle rail, preferably on the side web of the middle rail.
- the support roller is not fixed in the inner region of the middle rail or track, but can be stored on the flat side web of the center rail.
- the side web of the center rail is parallel to the mounting portion of the carcass rail.
- the support roller alone can take over the function of lifting and also supporting.
- the simple construction results from the arrangement of the support roller, which is located on a warehouse. This bearing is rigidly attached to the side bar of the center rail.
- the side bar is a flat area of a shaped profile, which acts as a middle rail.
- the support roller then runs in an area between this side web and the attachment portion of the carcass rail, which is also a pronounced surface of a molded profile. In Installation position of this drawer puller are these two surfaces, the mounting portion and the side bar, in a vertical position parallel to each other. Looking at the support roller in axial projection, so this is at least half of its circular area in the lower half of the side bar, also protrudes beyond the lower edge of the center rail.
- the bearing provided for the support roller has a recess in which the support roller is mounted limited height movable.
- the width of this recess is greater than the diameter of the receiving portion of the support roller.
- This recess can be defined in a detailed view over two longitudinal extensions.
- the first longitudinal extent is a slope with respect to the horizontal and the second longitudinal extent a deviation from the vertical. This results in a recess on which the support roller can move obliquely from bottom to top.
- the drawer rail has a running surface which is at right angles to the side bar.
- This tread works together with the support roller from the moment it ascends to the ramp.
- the drawer rail is raised and possibly also supported.

- FIG. 1a shows a drawer pull-out device 10 in the extended state. It can be seen in the upper part of the drawer rail 1, including the side bar 14 associated with the middle rail 2 and the ramp 12 on the carcass rail 3.
- the support roller 5 is located on the bearing 6, which is fixedly connected to the side bar 14 belonging to the center rail 2.
- the support roller 5 is located in an area in front of the ramp 12 and thus remains lying loosely in its recess 19. Thus, there is no interaction between ramp 12, support roller 5 and the tread 8 on the drawer rail. 1
- the rails slide so on their rolling elements 7 and 9 and the support roller 5 remains unloaded.
- FIG. 1 b shows how the support roller 5 now moves upwards in its recess 19 on the access area of the ramp 12, during the closing operation of the drawer pull-out device 10, and establishes contact with the running surface 8 on the drawer rail 1.
- the middle rail 2 and the drawer rail 1 no longer begins to support purely from the rolling elements 7 and 9, but also from the support roller 5.
- the gap between the carcass rail 3 and the center rail. 2 enlarged, as this is raised and supported.
- FIG. 1 c shows a drawer pull-out device in the retracted state, wherein now the support roller 5 is located on the running surface of the ramp 12. At this highest area of the ramp 12, the center rail 2 and the track rail 1 is now lifted and supported by the support roller 5 and the rolling elements 7 and 9 can be relieved.
- FIG. 2 shows, in an oblique view, a disassembled drawer pull-out device 10, formed from the carcass rail 3, which has a fastening section 15.
- This attachment portion 15 forms a vertical as soon as the drawer pull-out device is in the installed position.
- the carcass rail is connected to the furniture body and thus carries the entire unit of the drawer puller 10.
- On the carcass rail 3 is the rolling elements 7, on which subsequently the middle rail 2 is slidably disposed in the longitudinal direction.
- the rolling elements 9 On the middle rail 2 are the rolling elements 9, which allow cooperating with the drawer rail 1 to move in the longitudinal axis of the drawer pull-out device 10.
- the combination of support roller 5 and inner roller 4 is now also displayed as an additional application example, wherein the inner roller 4 is located with an inner bearing 20 in the end of the drawer rail 1.
- FIG. 3a shows on the left side the support roller 5 and the bearing 6.
- the vertical section A / A shown illustrates the distance between the roller 5 and the bearing 6.
- the receiving area of the support roller 5 is smaller in its diameter than the width of the recess 19. This illustrates that this is an axleless roller, which is characterized by low running forces.
- FIG. 3b once shows a built-in and a removed support roller 5 with bearing 6 and the recess 19.
- the recess 19 is formed obliquely in order to be able to ensure a movement of the support roller 5 up and down.
- FIG. 4 a shows a combination of support roller 5 and inner roller 4. Cooperating with the drawer rail 1, the center rail 2 and the carcass rail 3. The support roller 5 is not yet in the raised state by the ramp 12. This means that the drawer Ausziehvornchtung itself is located in a region in front of the end position and the drawer rail 1 and the center rail 2 move on their rolling elements 7 and 9.
- FIG. 4b shows how the support roller 5 is located on the ramp 12 and the middle rail 2 or the drawer rail 1 is raised.
- the inner roller 4 on its bottom bracket 20 is still free in this area and still takes no load.
- FIG. 4c now shows how the support roller 5 is located on the ramp 12 on the departure area. Now, the inner roller 4 has taken over the function of the outer roller 5 and supports the drawer rail 1 at its support surface 18 from the carcass rail 3 with its tread 17 from.
- the support roller 5 can already be completely relieved in this area, while the inner roller 4 can absorb the entire load.
- FIG. 5 shows an oblique view of the exemplary embodiment of the inner roller 4 in combination with the outer roller 5 in the extended state, before the support roller 5 ascends onto the ramp and the inner roller 4 makes contact with the running surface 17 of the carcass rail 3.
- FIG. 6a shows the previously mentioned application example of a combination of inner roller 4 and support roller 5 on the drawer extension device 10.
- the support roller 5 projects outside of the drawer roller Effective range of the ramp 12 is located and also the inner roller 4 is outside the effective range of the tread 17.
