Description

  The present invention relates to a drawer, which relates to a drawer having two side walls and a panel attached to the front face of these side walls and adjustable in a direction at least perpendicular to the drawer.

  The above type of drawer is known in many embodiments, especially with regard to the configuration of the panel fastening to the front of the side wall and the configuration of the means for adjusting the panel.

  The invention is based on the object of providing a drawer of a type according to a type distinguished by a simple construction, particularly with only a few individual parts for fixing and adjusting the panel on the front face of the side wall. ing.

  The purpose is that two clamping plates with housings extending in the direction of the side walls and transversely surrounding the side walls are attached to the panel on the inside facing the side walls, each housing being The height adjusting eccentric part and the squeezing eccentric part aligned therewith are received, and the squeezing eccentric part is engaged with the back surface of the thrust bearing in the area of each side wall, and the thrust bearing part Can be elastically pivoted out of the plane of the side wall, whereby the squeezing eccentric moves over the thrust bearing part while pushing the housing in the longitudinal direction of the side wall The thrust bearing part is bent, and after the thrust bearing part bounces, it is placed in a position to engage with the back of the thrust bearing. Use eccentric portion, in that present in the support state on the front recess of the side wall, it is achieved by the present invention.

  This type of configuration has relatively few and simple individual parts, guaranteeing a high degree of pre-installation or pre-assembly, making it easy to finally assemble such drawers, especially panels here and to adjust And achieved quickly.

  The clamping plate with the housing then receives the height adjusting eccentric and the clamping eccentric, but can be fully pre-mounted. In order to connect the panel to the drawer side wall, the panel with the housing must simply be pushed over the side wall and then locked against the clamping area inside the side wall. Thus, the panel is also pre-fixed to the drawer even when it does not actuate the clamping eccentric, and the drawer can be transported in this situation without risk of losing the panel.

  In order to make it easier for the clamping eccentric part to move onto the thrust bearing part, the clamping eccentric part and / or the thrust bearing part have a thrust bearing part laterally outside their reference position. An access ramp is provided that makes it easier to flex.

  According to yet another feature of the invention, the thrust bearing portion comprises a flexible spring element formed by an open notch and provided on the side wall.

  The thrust bearing part is thus produced in one piece with the side wall, which is of course particularly advantageous from a cost standpoint.

  However, the thrust bearing portion may be provided with a mounting part fixed to the side wall.

  This type of mounting part is preferably implemented such that the mounting part engages in a corresponding recess in the side wall.

  If separate mounting parts are used to form the thrust bearing part, these separate mounting parts are actually independent of the material used for the side walls and by special treatment of the side walls. The clamping eccentric part is relatively easy to move over these thrust bearing parts and is structurally shaped so that the clamping eccentric part further engages the back of the thrust bearing. The advantage is that it can be done.

  Further features of the invention are the subject of further dependent claims.

  Exemplary embodiments of the present invention are illustrated in the accompanying drawings and are described in detail below.

  In these figures, the complete drawer with all of its individual parts is omitted for reasons of clarity, but this is basically the case for the drawer panel 1 in front of the drawer sidewall. This is because it relates to the fastening and adjusting characteristics (see FIGS. 15 and 16). Also, for reasons of simplicity, only one of the drawer side walls 2 is shown.

  For the purpose of clamping this panel 1 to the side walls 2, a clamping plate 3 having a housing 4 arranged thereon extending in the direction of the side walls 2 at the opposite positions on the respective side walls 2 is respectively provided. Fastened to the panel 1, the housing 4 can receive the height adjusting eccentric part 5 and the clamping eccentric part 6 and can be pressed onto the side wall 2 to surround the side wall 2 in a transverse manner. . In the pressed state, the height adjusting eccentric part 5 rests in a supported state in the front recess 7 of the side wall 2, and the tightening eccentric part 6 is exemplified in FIGS. 10, 11 and 16. Engage with the back of the thrust bearing 8 inside the side wall 2 shown for purposes.

  The possible vertical adjustment of the panel 1 with respect to the drawer can be carried out additionally by means of a height-adjusting eccentric part 5, and the panel 1 is fixed to the side wall 2 by means of a clamping eccentric part 6 and a thrust bearing 8. Can be firmly fixed to the front.

  All basic embodiments share this basic construction principle.

  It is also shared by all exemplary embodiments that the thrust bearing portion 9 with a particular thrust bearing 8 can be elastically pivoted out of the plane of the side wall 2. When the housing 4 is pressed against the side wall 2, the clamping eccentric 6 can be moved onto the thrust bearing part 9 by flexing it transversely until it rests in the area of the recess 10. The thrust bearing 8 is formed by the boundary facing the panel 1. In this position, the thrust bearing portion 9 bounces back to its initial position, and the tightening eccentric portion 6 engages the back surface of the thrust bearing 8.

  This is particularly clearly shown in FIGS. 15 and 16.

  As soon as the clamping eccentric 6 is pressed into the recess 10 and engages the back of the thrust bearing 8, the panel 1 is first connected in a tethered manner to the drawer. By operating the tightening eccentric portion 6, the panel 1 can be firmly fixed to the front surface of the side wall 2.

  When the height adjustment of the panel 1 is necessary, the height adjustment is performed by operating the height adjusting eccentric portion 5 before final fixing of the panel 1.

  In the following, specific features of each representative embodiment are described.

  FIG. 1 shows a fastening plate 3 having a vertical leg 3 a extending in the direction of the side wall 2, and the leg 3 a is manufactured in one piece with the fastening plate 3. A first half of the housing 4 is formed by the legs 3a. The plate 11 made separately includes a base bent portion 11a, and is inserted into the slot 3b of the fastening plate 3 by using the bent portion 11a, and then parallel to the leg portion 3a. Can be put in position. In this position, the plate 11 is connected to the clamping plate 3 by an arbitrary method such as welding, adhesion, pressure welding or the like. In this way, the housing 4 is formed by the leg 3a and the plate 11.

  The height adjusting eccentric portion 5 and the tightening eccentric portion 6 are provided in the holes 12 and 13 of the leg portion 3a provided for this purpose, and both the height adjusting eccentric portion 5 and the tightening eccentric portion 6 are provided. Are each riveted so that they are still rotatable.

  As further shown in FIG. 1, the front recess 7 on the inside of the wall 2 opens into a recess 14 into which the attachment part 15 is inserted and engaged. The mounting part 15 made of elastic plastic in one piece forms the thrust bearing part 9 and has an opening 10 defined in the clamping plate 3, so that its side is clamped. It is opposed to the panel 1 by an end forming a thrust bearing 8 for the attaching eccentric portion 6.

  On the side of the clamping plate 3 and thus facing the panel 1, the mounting part 15 is provided with a hook-like access ramp 16, which is particularly clearly shown in FIG. 7. In the intermediate stage of installation shown in FIG. 15, this access ramp 16 is in the opposite position of the clamping eccentric 6 which is preferably also implemented with the access ramp. Through yet another movement through the approaching inclined surface 16 in the mounting part 15 and the approaching inclined surface 16 in the clamping eccentric part 6, the thrust bearing part 9 now elastically moves laterally out of the plane of the side wall 2. can do. Such a possibility causes the clamping eccentric part 6 to be moved onto the thrust bearing part 9 until the clamping eccentric part 6 reaches the area of the opening 10 of the mounting part 15. This now bounces back to its starting position and the clamping eccentric 6 engages the back of the thrust bearing 8 as shown very clearly in FIG.

  In the position shown in FIG. 16, the panel 1 is initially connected in a virtually anchored manner to the drawer. By actuating the clamping eccentric 6, it is here pressed against the thrust bearing 8, causing a fixed clamping of the panel 1 on the front side of the side wall 2.

  When the height of the panel 1 needs to be adjusted, this is done before the fastening eccentric part 6 is fixed.

  FIG. 16 also shows very clearly that an opening 17 is provided in the leg 3 a in the area of the thrust bearing part 9. This opening 17 is provided by a tool such as a screwdriver in order to be able to pivot the thrust bearing part 9 out of the area of movement of the clamping eccentric 6 if the panel 1 needs to be removed. Used for the purpose of being able to guide.

  As shown particularly clearly in FIGS. 17 and 16, the mounting part includes a spring which is supported in the mounting state of the mounting part 15 on one side of the side wall 2 away from the panel 1 in its rear end region. A thin plate 18 is provided, and a contact area 19 of the mounting part 15 is supported on the other side of the specific side wall 2 at a position opposite to the spring thin plate 18. In this way, the mounting part 15 is fixed in its rear end area associated with the side wall 2.

  In addition, a locking cam 20 (see FIG. 6) is molded into the rear end area of the mounting part 15, which is the recess 14 in the side wall 2 when the mounting part 15 is mounted. Engage with the back of a protrusion 21 (see FIG. 1a) that projects into the area.

  By means of the measures described above, the mounting part 15 is fixed to the side wall 2 transversely to the side wall 2 and in the longitudinal direction of the side wall 2.

  Further, as clearly shown in FIG. 16, the tightening surface of the tightening eccentric portion 6 and the tightening surface of the thrust bearing 8 interact with each other so that the shaft of rotation of the tightening eccentric portion 6 is rotated. The receiving part 15 having the tightening eccentric portion 6 and the thrust bearing 8 is not likely to loosen from each other even when a dynamic load is applied.

  In addition, as shown in the alternative embodiment in FIG. 14, the mounting part 15 enlarged in relation thereto projects into the transition area between the recess 7 and the recess 14 of the side wall 2. A protruding piece 15a may be provided. In this way, a close-fitting overlap of the side walls 2 is brought about in these stepped transition areas, and at least in the tightened state, some kind of close-fitting occurs between the side walls 2 and the mounting part 15. However, the reason is that the transition area engages in the recess of the mounting part 15 defined by the projection 15a in the clamped state. If necessary, it is also sufficient to make a snug fit in only one transition area.

  As can be seen from FIGS. 2 to 5, the clamping plate 3 having the housing 4 is, for example, a leg 3 a which can be implemented as a bent part and can be connected by spot welding after being assembled with the clamping plate 3. And can be manufactured as a whole from a plurality of individual parts such as the plate 11.

  The clamping eccentric part 6 is conveniently attached in this case before the plate 11 is connected to the clamping plate 3.

  However, instead of this, it is shown completely in FIG. 5 and comprises a fastening plate 3 made of legs 3a and a plate 11 and a housing 4 and is manufactured in one piece as an injection-molded part, for example from metal or plastic. It is also possible to consider the mounting unit that is used.

  FIGS. 18, 19 and 20a-e show an exemplary embodiment of the present invention in which the mounting part 15 is manufactured as an integral stamped part made of metal.

  A fitting made from this type of metal is designed by forming an appropriate spring tab and other supporting parts so that the fitting can be clipped into the recess 14 in the side wall 2. You can also

  In FIG. 21, the side wall 2 is designed by proper positioning of the open notch 22 such that the thrust bearing part 9 with the thrust bearing 8 for the clamping eccentric 6 is designed as an arcuate spring element. The conclusion is that there is a possibility. Due to such a result of the object shown in FIGS. 21 to 23, the use of an additional mounting part 15 can be omitted.

  In short, the greatest advantage of the present invention is that it can be pre-manufactured and already pre-installed to a significant extent, many parts that are required to be fastened and adjusted to the panel 1 in the drawer. It should be noted once again. The pre-mounting unit can be provided so that even end users with little technical experience can secure the panel 1 in the drawer and adjust it as required.

  In any case, the clamping plate 3 is always provided with elliptical holes 3c through which the clamping screws are guided for mounting in the panel 1, because the horizontal adjustment of the panel 1 is not necessary for these elliptical holes. It is because it can also be performed by 3c.
