Description

  The present invention relates to a drawer arrangement comprising a container rail pre-attached to a drawer container and a drawer extension guide having a movable drawer rail, the drawer container being extended by the container rail to support the furniture carcass in an extendable manner. The container rail is substantially U-shaped in cross section and has a portion for receiving the drawer rail in an attached state.

  Such container rails are often fitted (accommodated) in a recess on the back side of the drawer container and serve to connect the drawer container to the movable rail of the drawer extension guide. In that case, the drawer extension guide may be in the form of a two-part rail system having a carcass rail fixed to the furniture carcass and a drawer rail movable relative thereto, or a three-part rail system. A central rail is also movably supported between the carcass rail and the drawer rail so that the configuration can be selectively adopted and thus the drawer container can be fully extended relative to the furniture carcass. In a conventional solution for connecting a drawer container to two typical drawer extension guides pre-mounted on a furniture carcass, the drawer container is a container rail fixed to the bottom of the drawer relative to the drawer rail of the drawer extension guide. And is connected to corresponding fixing means attached to the drawer extension guide. For this purpose, the operator is generally required to move the drawer container along the drawer rail, in which case the drawer container is guided exclusively by the worker until it is secured to the drawer rail, whereby the side of the drawer container is Movement can take place during a pushing-in movement. It is not uncommon for the drawer side walls to be damaged by tilting the drawer container.

  The object of the present invention is to provide a drawer arrangement of the general type described in the first part of the specification while avoiding the aforementioned disadvantages, and the present invention is directed to a drawer extension guide associated with the drawer. It aims to provide especially guidance and pre-positioning of the drawer container during the installation of the container.

  According to the invention, this is achieved by the features of claim 1. Further advantageous configurations of the invention are listed in the appended claims.

  Therefore, according to the present invention, it is provided that the U-shaped portion is provided with at least one abutting portion with respect to the drawer rail, and the abutting portion extends in the longitudinal direction of the rail.

It can provide a stable attachment of the drawer container to the drawer rail of the drawer extension guide, in particular this can avoid tilting when attaching the drawer container to the drawer extension guide. In that sense, thanks to the drawer container being inserted in a distorted position, it is further avoided that the drawer side wall of the drawer container is damaged, for example in the assembly procedure for the carcass rail of the drawer extension guide and / or the side wall of the furniture carcass. sell. It is particularly important when the drawer sidewall has a vulnerable outer surface, for example a vulnerable decorative part. In that regard, the proposed at least one abutment is particularly beneficial when attaching the drawer container to the drawer extension guide. After the installation has been carried out, the drawer rail can be oriented such that it can no longer be supported by the abutment to the container rail, for example by appropriate fixing to the container rail.

  Preferably, the at least one abutment may be formed by a series of individual abutments that generally form an abutment that preferably extends in the longitudinal direction of the rail. Structurally, it is formed, for example, by at least one knob stamped or punched from the container rail, preferably by a series of knobs stamped or stamped from the container rail along a conceptual straight line. It can be realized by the contact portion. In that case, the knobs can be arranged on the horizontal rim of the container rail and / or on the leg of the U-shaped part, thus forming one or more abutments of the drawer rail as a whole.

  The inner width of the U-shaped part of the container rail can be reduced by at least one abutment so that a pre-positioning of the container rail that is subsequently fixed to the drawer rail is achieved. For this purpose, the U-shaped part may have a leg, the abutting part that can be arranged on the horizontal rim of the U-shaped part is arranged horizontally spaced from the leg, and the remaining inner width of the U-shaped part is It is greater than or equal to the width of the drawer rail. In that case, the leg of the U-shaped part and the contact part can form a guide means for the drawer rail in the longitudinal direction of the rail. From another point of view, the container rail can be movably supported on the pull-out rail by at least one abutment in the longitudinal direction of the rail with minimal play.

  Alternatively or additionally, the U-shaped leg may also have an abutment. In that case, the U-shaped part has a horizontal rim, the horizontal rim has a first abutting part, the U-shaped part has a leg, the leg has a second abutting part, It can be preferably provided that the remaining inner width between the abutment and the second abutment is greater than or equal to the width of the drawer rail.

  Depending on whether there is only one abutment, or for example two abutments, the inner width remaining between the abutment of the leg and the horizontal rim, or the first abutment of the leg and the horizontal There may be another remaining inner width between the second abutment of the rim, preferably each inner width being only slightly larger than the width of the drawer rail.

  Preferably, in that case, it may be provided that the respective remaining inner width is at most 5%, preferably at most 1% greater than the width of the drawer rail. For example, each remaining inner width may be conditioned to be greater than the width of the drawer rail by a maximum of 0.8 mm in the range of 0.2 mm to 1.6 mm.

  In a further variant of the invention, the container rail can be designed with fixing means for releasably fixing the drawer rail. In particular, it can be conditioned on the releasable coupling for connecting the container rail to the drawer rail that is arranged in the front end region of the container rail in the U-shaped part.

  In a preferred embodiment, the container rail may be conditioned from being made from a metallic material.

  In a particularly preferred embodiment, a pair of container rails of the general designated type for a drawer container is provided, where only one of the two container rails has at least one abutment extending in the longitudinal direction of the rail, The container rail does not have a U-shaped contact portion.

Further details and advantages of the present invention are explained below by means of a specific description. In the drawing

FIG. 6 shows a front view of the container rail shown in FIG. 5. Fig. 6 shows a detailed view of the container rail shown in Fig. 5; Fig. 6 shows a detailed view of the container rail shown in Fig. 5; Fig. 6 shows a perspective view from below of an embodiment drawer container secured to the proposed container rail drawer container. FIG. 8 shows a perspective view from above of furniture with a plurality of drawer containers as shown in FIG. 7.

  FIG. 1 shows a front view of the drawer container 2 and the container rails 1, 1 ′ attached to the drawer container 2, while FIG. 1 a shows the area marked with a circle in FIG. 1 on an enlarged scale. The container rails 1, 1 ′ serve to fix the drawer container 2 to, for example, a drawer extension guide 5 that is pre-mounted on a furniture carcass 3 (not shown here), and the drawer container 2 extends from the furniture carcass 3. Or movably mounted in the longitudinal direction L of the rail so as to be moved into the furniture carcass 3. The drawer extension guide 5 includes at least one carcass rail 16 each typically fixed to the carcass, and a drawer rail 4 movable relative to the carcass in the longitudinal direction L of the rail (see FIG. 4). Including. Furthermore, a central rail 17 can be arranged between the carcass rail 16 and the drawer rail 4, and the drawer container 2 can be completely extended from the furniture carcass 3 by the central rail.

  On its back side in the region of the outer edge, the drawer bottom 11 of the drawer container 2 opens towards the outer edge of the drawer bottom 11 so that the container rails 1, 1 ′ fit into the recesses 12 in the drawer bottom 11. It has a recess 12. In this example, the recess 12 extends substantially the entire length of the drawer bottom 11. The container rails 1, 1 ′ have U-shaped parts 6 that are adjacent by respective horizontal contact rims 10. In this case, the U-shaped part 6 includes legs (legs) 9 each protruding substantially perpendicularly from the respective horizontal contact rim 10. The container rails 1, 1 ′ can be fixed to the rear surface of the drawer bottom 11, for example by means of suitable fixing means, for example by screw connection, in the horizontal contact rim 10 and / or the legs 9 of the container rails 1, 1 ′.

  In the illustrated example, the U-shaped portion 6 of the container rail 1 has a horizontal rim 8, and the horizontal rim 8 abuts in the longitudinal direction L of the rail of the drawer rail 4 (see FIG. 2) of the drawer extension guide 5. Part 7. In this case, the abutment 7 is arranged horizontally spaced from the leg 9 so that the remaining inner width B of the U-shaped part 6 is correspondingly reduced.

  Further, in this example, the leg 9 has a second abutting portion 7a (see FIG. 2), and is located between the first abutting portion 7 of the horizontal rim 8 and the second abutting portion 7a of the leg 9. The remaining inner width B ′ is greater than or equal to the width b of the drawer rail 4. In this case, the remaining inner width B ′ is slightly smaller than the width b of the drawer rail 4 so that the container rail 1 is adapted to the drawer rail 4 with very little play and thus is guided very well. It's just big. Preferably, in that respect, the play between the vertical leg of the drawer rail 4 and the respective abutment 7, 7 a is only 0.2 mm to 0.8 mm, preferably only 0.1 mm to 0.4 mm. It can be a condition.

  The structure is such that, when the drawer container 2 is suspended by being engaged with the container rails 1, 1 ′ fixed to the drawer container 2 by the drawer rail 4 of the drawer extension guide 5, the container rails 1, 1 ′ are particularly pulled out. Good in having a little play so that the tilt of the drawer container 2 is avoided when pushed by the coupling 14 arranged in the U-shaped part 6 in the drawer container 2 to connect to 4, for example Provide guidance (see FIG. 3).

  The abutment portions 7, 7 a of the container rail 1 thus provide an easy fit of the drawer container 2 to the drawer extension guide 5. On the other hand, the contact portions 7, 7 a of the container rail 1 can further simplify the connection of the drawer rail 4 to the coupling 14 as the container rail 1, 1 ′, thus corresponding to the drawer rail 4. The coupling 14 can be properly pre-positioned with respect to the pull-out rail 4 by the abutment 7, 7 a so that it can be easily connected to the device. Third, damage to the drawer side wall 15 can also be prevented by avoiding the tilt of the drawer container 2 during the fitting of the drawer container 2 to the drawer rail 4.

  As shown in the example of FIG. 1, the pre-positioning that depends on the abutment of the drawer container 2 with respect to the drawer extension guide 5, in particular with respect to the carcass rail 16 of the drawer extension guide 5, depends on the drawer side wall 15 and the carcass rail 16 or furniture. An appropriate space is provided between the side wall (not shown) of the carcass 3 and a vertical leg (vertical leg) 18, and the carcass rail 16 can be fixed to the side wall of the furniture carcass 3. When the drawer container 2 is pushed along the drawer extension guide 5, the guide in the longitudinal direction L of the rail suitably provided by the at least one abutment 7 is the vertical leg 18 of the drawer side wall 15 and the carcass rail 16 or furniture. This means that there is no contact with the side wall of the carcass 3, whereby it is possible to avoid damage, in particular scratches on the sensitive outer surface of the drawer side wall 15.

  FIG. 2 shows a perspective view from below of the proposed container rail variant. In this embodiment, the container rail 1 has two contact portions 7 and 7 a for guiding the drawer 4. In this case, the first abutment 7 is arranged on the horizontal rim 8 of the U-shaped part 6 and is formed from a series of individual abutments 7 ′ by knobs punched from the container rail 1. The second abutment 7a is in the leg 9 of the U-shaped part 6 and is formed from a series of individual abutments 7a 'by appropriate embossing of the container rail 1.

  FIG. 3 shows a perspective view from below of the drawer rails 1, 1 with the drawer side walls 15 fixed to the drawer rails 1, 1 ′, FIG. 3 a is a circle in FIG. 3 of the scale identified by A and enlarged. Indicates the marked area. The container rail 1 has at least one abutment 7, in this embodiment the abutment 7 is formed by a series of individual abutments 7 ′. Specifically, in this case, the contact portion 7 is formed by a series of knobs that are stamped or punched from the container rail 1 along a conceptual straight line extending in the longitudinal direction L of the rail. Those knobs which are arranged on the horizontal rim 8 of the U-shaped part of the container rail 1 and are appropriately spaced from the leg 9 of the U-shaped part 6 are in the longitudinal direction of the rail relative to the drawer rail 4 of the drawer extension guide 5 The contact portion 7 extending to L is configured as a whole.
