Description

  The present invention relates to cabinet furniture having a withdrawal portion, preferably a drawer. This extraction part is connected to the traveling rail of the extraction guide, fixed in all coordinate directions with respect to the traveling rail, and can be removed from the traveling rail without tools if necessary. In the area, it is prevented from being lifted off the rail and not displaced laterally relative to the rail in the rear area.

  This kind of cabinet is generally known and can generally be fixed in a simple manner in relation to the guide rail of the extraction guide and, if necessary, in a simple way from the run rail without tool assistance Provides the advantage that it can be removed as well.

  The present invention is based on the object of providing cabinet furniture of the type described above, and the releasable connection between the pull-out part and the running rail uses exceptionally simple means from a structural point of view. Realized, the potential removal of the pull-out part from the running rail is easily possible even by a technically unskilled person.

  This object is achieved according to the invention in such a way that the molded parts are respectively attached to the drawn part or the running rail in order to couple the drawn part to the front end region of the running rail, each of the molded parts being parallel to each other. Extending to, spaced apart from each other and with the respective running rail open to the front side of the running rail, in the region of the longitudinal slit, or on the rear side of the withdrawal portion corresponding to the withdrawal portion to be joined With two spring bars penetrating in the region of the longitudinal slit opening towards the two spring bars with lugs extending away from each other in a direction opposite to the end of the spring bar penetrating the longitudinal slit And at a distance from each other in the opposite direction to the end of the spring bar facing the opening of each longitudinal slit. A holding leg that is bent and is supported in a manner that fits formally and / or friction-locks in each longitudinal slit against displacement in the direction of the front of the running rail .

  In addition to the means in the rear end region of the known traveling rail, only two molded parts are required for releasably fixing the extraction part according to the invention on the traveling rail of the extraction guide, Is fixed to the extraction part in the front end region of the molded part, and is fixed in all three coordinate directions after coupling with the traveling rail.

  Another solution is to fix the molded part in the area in front of the running rail and, after joining with the drawing part, fix the molded part in all three coordinate directions within the longitudinal slit of the drawing part. The longitudinal slit is open towards the rear side of the withdrawal part.

  This can be done in such a way that when the withdrawal part needs to be removed from the traveling rail, the withdrawal part is lifted upwards in the front end region of the withdrawal part relative to the traveling rail, thereby Separation of the molded part from the rail is caused. This means that the lugs protruding at the end of the spring bar that penetrate the longitudinal slit are compressed by applying an upward force by lifting the pull-out part as a result of the elastic properties of the spring bar. This is possible in such a way that it can be pulled through the slit.

  However, the accidental release of this direction is completely excluded. Each force is not suitable for compressing the protruding lug at normal operation or at the lower end of the spring bar to such an extent that the protruding lug can be guided upward through the respective longitudinal slit. This is because it does not occur only in size (i.e., when the withdrawal portion is withdrawn or pushed in).

  As soon as the withdrawal part is separated from the running rail in the front end region (as described above) after the intended operation, the withdrawal part can be withdrawn from the running rail in the longitudinal direction of the withdrawal part. Fixing the pull-out part in relation to the travel rail is carried out only in the transverse direction with respect to the longitudinal axis of the travel rail in the rear end region and is therefore free from obstructions in the longitudinal direction of the travel rail. This is because drawing is possible.

  If the withdrawal part is to be reconnected to the traveling rail, the withdrawal part is placed horizontally on the traveling rail, in which two molded parts are placed in front of the open end of the longitudinal slit. Yes. As a result, each molded part can be pushed into the longitudinal slit provided for this purpose by displacing the withdrawal part in the insertion direction with the spring bar of each molded part, and at the end of the lug When lugs extending away from each other in opposite directions pass through the longitudinal slit, they engage in the area of the longitudinal slit behind the traveling rail so that the withdrawal part does not accidentally lift off the traveling rail. To. A retaining leg provided at the end of the spring bar facing the respective opening of the longitudinal slit is compressed during insertion into the longitudinal slit and fits formally and / or frictionally into the longitudinal slit. It can be supported in the longitudinal slit in a locked manner. As a result, the withdrawal portion is securely fixed with respect to the relative displacement associated with the travel rail, and thus the withdrawal portion is secured in all possible coordinate directions with respect to the travel rail.

  Other features of the invention are the subject of the dependent claims.

  Embodiments of the invention are illustrated in the accompanying drawings and are described in more detail below.

FIG. 4 is various details of a running rail and a molded part coupled to the rail according to another embodiment of the present invention. FIG. 12 b shows various views of the rail for running and the molded part in the viewing direction according to FIG. 12 a. FIG. 3 is a diagram of various molded parts. It is a fragmentary sectional view of the connection area | region of a molded component and the adapter of a drawing-out part. FIG. 16 is a partial cross-sectional view corresponding to FIG. 15 with a connection between the molded part and the adapter that can be displaced within limits.

  1 to 7 show the whole extraction part of cabinet furniture not shown in detail by reference numeral 1. The withdrawal portion is configured as a drawer in this particular embodiment.

  As is well known, the extraction part 1 is held and guided in a longitudinally displaceable manner (ie in the front-rear direction) by means of an extraction guide 2 in the cabinet furniture body.

  The pull-out guide 2 is arranged in two regions of the pull-out part 1 extending in the front-rear direction, and is provided with at least one guide rail 3 that can be fixed on the side of the main body, and a traveling rail 4 that can be connected to the pull-out part 1. Is provided. As an option, the pull-out guide 2 extends the pull-out and in this case also comprises a middle rail with a dependent relationship.

  The connection between the pull-out portion 1 and the travel rail 4 of the pull-out guide 2 is performed by connecting a so-called catch hook 5 provided in a rear end region on the travel rail 4 and each travel rail 4 when the pull-out portion 1 is attached. This is done in the rear region of the running rail 4 and the withdrawal part 1 by means of an opening (not shown) in the rear end area of the withdrawal part 1 in which the catch hook 5 engages. This connection technique within the trailing edge region is generally known and will therefore not be described in more detail. As a result of the catch hook 5 being in the rear end region of the travel rail 4 and the catch hook 5 being engaged in the rear opening of the pull-out portion 1, the pull-out portion 1 is relative to the travel rail 4 in the rear end region. It should be noted that the longitudinal axis of the traveling rail 4 is prevented from being displaced not only vertically but also horizontally. The extraction part 1 cannot be fixed in the longitudinal direction of the traveling rail 4 with the catch hook 5.

  It will be understood that other known variants can be used in the rear end region of the running rail 4 instead of the described connection of the withdrawal part 1.

  In the front end region, the drawing part 1 and the traveling rail 4 are connected to each other via a molded part 6 that is fastened directly or indirectly to the adapter 7 on the drawing part 1, and the adapter 7 is in a known manner. The pull-out portion 1 is firmly connected.

  The molded part 6 is preferably made in one piece of metal, preferably spring steel, with a pocket 8 in the connection region for the adapter 7 and a tongue 9 protruding from the adapter 7 engaging in the adapter 7. become. This is particularly illustrated in FIGS. 15 and 16.

  In this regard, the material layer of the molded part 6 covering the upper side of the tongue 9 is provided with a latch tongue 10 projecting in the direction of the pocket 8, and the latch tongue 10 is provided in each tongue 9. Engage in the recess 11. The recess 11 can be dimensioned such that the molded part 7 can no longer be displaced after the latching tongue 10 has latched into the recess 11. That is, the dimensions of the recess 11 are such that the molded part 6 can still be slightly displaced laterally with respect to the longitudinal axis of the traveling rail 4, as shown in FIG. It is also possible. Preferably, the molded part 6 is non-displaceable and the other molded part 6 is displaceable within limits to allow for tolerance correction between two traveling rails 4 arranged at a distance from each other. One embodiment is preferred within the overall concept of the invention.

  Each molded part 6 is provided with two spring bars 12 extending parallel to each other and arranged at a distance from each other, and the two spring bars 12 are in a direction opposite to the lower end of the spring bar 12. The lugs 13 are spread apart from each other.

  At the end of the spring bar 12 facing the front side of the traveling rail 4, the spring bar 12 is similarly provided with holding legs 14 that are spread apart from each other in opposite directions.

  At the front end portion of the spring bar 12 as viewed in the insertion direction, the spring bar 12 is provided with a guide lug 15 that is bent away from each other by facing each other and starts from the spring bar 12.

  Such a structural configuration of the molded part 6 is shown in greater detail in FIGS. 14a to 14f.

  Each of the traveling rails 4 is provided with a longitudinal slit 16 that opens toward the front end of the traveling rail 4. Each longitudinal slit 16 is provided with an insertion opening 17, and the width of the insertion opening 17 is smaller than the distance of the free ends of the holding legs 14 which are spread apart from each other. Each insertion opening 17 is limited by an insertion bevel 18 as seen towards the front side of the traveling rail 4.

  As a result of the guide lugs 15 and the insertion bevels 18 facing each other, the molded parts 18 can be reliably introduced into the longitudinal slits 16 of the respective traveling rails 4. Since all the molded parts 6 are firmly connected to the drawing part 1 in the insertion direction, all the molded parts 6 are inserted into the respective longitudinal slits 16 during the insertion of the drawing part 1 into the furniture body. Displaces until reaching the final limit of the insertion path. In this inserted state, the free end of the holding leg 14 is supported in the region 19 of the longitudinal slit 16 which is expanded in relation to the insertion opening 17, which is an implementation of the invention according to FIGS. 11 a to 11 c. This can be done by providing a notch in the outer edge of the retaining leg 14 on the latching teeth 20 or on the linear flank of the extended region 19 of the longitudinal slit 16 as in the form. In other words, the holding legs 14 can be fixed, fixed or supported against pushing back of the molded part 6 in a form-fitting manner and / or a friction-locking manner.

  As a result, the extraction portion 1 is prevented from being displaced in the front-rear direction with respect to the traveling rail 4 after being completely inserted into the furniture body for the first time.

  As clearly shown in FIGS. 13, 15, and 16, the spring bar 12 of the molded part 6 is in the section 22 of the longitudinal slit 16 in the inserted state, and the width of the section 22 is two spring bars 12. The length of the section 22 is dimensioned such that the lug 13 is already in the compartment 22 at the position when the holding leg 14 passes through the insertion opening 17. In embodiments having latching teeth 20, the dimensions of the section 22 in the area of the latching teeth 20 are determined by the teeth on the opposing flank of the longitudinal slit 16. As a result, the extraction portion 1 is fixed against horizontal lateral displacement with respect to the traveling rail 4.

  The withdrawal of the withdrawal part 1 from the running rail 4 is hindered by a lug 13 which is spread apart in the opposite direction at the lower end of the spring bar 12, which is also clearly shown in FIGS. ing. As a result, the drawn-out portion 1 is fixed after completing the mounting in all coordinate directions with respect to the relative displacement with the traveling rail 4.

  In the case of a removal that may be necessary or desirable, it is sufficient to lift the withdrawal part upward in the front end region of the withdrawal part, as shown in FIG. While lifting, the lugs 13 are pressed together as a result of the spring capacity of the entire molded part and move in the recessed section 22 of the longitudinal slit 16. Therefore, as shown in FIG. 3, the pull-out portion 1 is separated from the front end region of the traveling rail 4 and can be completely separated from the traveling rail 4 by further pulling from the furniture body. This is because the extraction portion 1 can be easily pulled out from the rear catch hook 5 of the traveling rail 4.

  When the extraction part 1 is to be reattached, it is sufficient to place the extraction part 1 on the traveling rail 4 in the horizontal state of the extraction part 1, in this state as shown in more detail in FIGS. 4 and 5. The molded part 6 is still arranged outside the longitudinal slit 16. Due to the sliding of the pull-out portion 1, the catch hook 5 enters the engagement region toward the rear opening of the pull-out portion 1, and the molded part 6 receives the temporary compression of the rear holding leg 14 and receives the insertion opening 17. Into the region of the longitudinal slit 16 and then fixed in the manner described above in connection with the traveling rail 4.

  It has already been mentioned above that one of the molded parts 6 can be moved laterally within certain limits in relation to the traveling rail 4 so that tolerances can be corrected at different distances of the traveling rail 4 relative to each other. Has been. Passing the molded part 6 through the longitudinal slit 16 is simplified by inserting one insertion bevel 18 and a guide lug 15 forming the insertion tip.

  In the illustrated embodiment, the molded part 6 is fixed to the aforementioned tongue 9 of the adapter 7, and a part of the adapter 7 is firmly connected to the withdrawal part 1.

  The adapter 7 is used in a known manner to support the side frame. However, it should be noted that the molded part 6 can also be fastened directly to the withdrawal part if the withdrawal part is arranged differently and does not have an adapter.

  The latching teeth 20 on which the ends of the holding legs 14 are supported can be arranged symmetrically on both sides of the longitudinal slit 16, as in the embodiment according to FIGS. 11a to 11c. However, it is also possible to arrange the latching teeth 20 in a manner that is offset from each other in the longitudinal direction of the longitudinal slit 16, so that a finer grid configuration requires very fine areas of the latching teeth 20. Realized, each with only one retaining leg 14 being able to engage in a corresponding latching tooth 20 of these arrangements. The offset latching teeth 20 are shown in more detail in FIGS. 5 and 7, and the engagement of the retaining legs 14 on the latching teeth 20 is shown in FIG.

  Another solution to the embodiment shown above is that the molded part 6 can also be fixed to the traveling rail 4. This is also advantageous when the molded part 6 is fastened and the other molded part 6 is fastened so that it can be displaced laterally within limits with respect to the associated running rail. In this case, the longitudinal slit 16 that opens toward the rear side of the extraction portion is provided in each of the extraction portion 1 or the adapter 7 fixed to the extraction portion 1. This is substantially related to the kinematic reversal of the structural principle according to the embodiments described above.
