Drawer

The invention relates to a drawer in the Art defined in the preamble of claim 1.

In the case of a drawer with such a clamping device provided is CDE-GM 78 11 948), both the tensioning element and the rotary bolt sit on a retaining bolt the cover, the twist-lock being rotatable on the retaining bolt, while the clamping element is non-rotatable on the retaining bolt is held. The axial pressure surface of the rotary lock consists of an inclined plane or wedge surface on that The broad side of the rotating bolt facing away from the drawer and facing the panel. The clamping element axially directly adjoins the rotary latch and points to the broad side that leads to the rotary latch and to the drawer indicates a corresponding inclined plane or wedge surface. On the other, facing the panel The clamping element carries its own clamping surface on the broad side, with which it draws against a front wall of the drawer is cash. This front wall runs at a distance from the Inner wall of the drawer and, together with this, forms a cavity that is located in between and is open at the bottom. aside from that is this forehand with a downwardly open slit Mistake.

So this is relatively complicated and requires specialist knowledge and skill. The Quarter-Turn with an inclined plane is pivoted around the pivot axis by a radially protruding lever.

This in turn requires, depending on the work, in a constrained position and makes many hands necessary, so that the attachment and adjustment of the panel cannot be done by one person alone. Otherwise is a drawer with the known clamping device is relatively expensive; Since the individual elements of the clamping device in Axial direction of the swivel axis are lined up one behind the other, the space requirement in this axial direction is considerable great. It is therefore necessary to make the cavity or space in the area of the drawer front wall relatively wide to design what sometimes looks ugly and is contrary to the endeavor., the drawer walls to make it as narrow as possible so that one is given

The object of the invention is to be found> at 'a drawer = box defined in the preamble of claim 1 Generate remedy and avoid the disadvantages set out above. The drawer should be placed in the table its jig as simple and cheap as possible. The aim is that the design the clamping device does not force you to leave the drawer open at the bottom in the area of its front wall, with all other disadvantages resulting therefrom. In addition, the aim is> the dimensions of the clamping device in the direction of the pivot axis of the rotary bolt as small as possible so that the space to be provided for it can be as narrow as possible and the Use of the clamping device is not restricted to special types of drawers. Incidentally, the Drawers with regard to the jig be designed so that the latter can also be used by laypeople and without special Expertise can be handled, if necessary, but above all including a fastening of the panel the fine adjustment can be done by a single person if possible. As a further essential The aim is a design such that when attaching the diaphragm there is no risk that the When you let go of the cover and, for example, before fine-tuning and tightening, it immediately detaches itself from the drawer and falls down by itself. Rather, it should be ensured that the attached cover is nice before tightening The drawer side is held in such a way that the panel can be fine-tuned without the risk of the panel being automatically detached can be carried out by a single person relative to the drawer.

With this innovative design, the panel is fixed and clamped to the drawer by the fact that the clamping surfaces of the clamping elements facing the drawer are pressed directly against the contact surfaces on the drawer facing the panel in any case, this saves space in the direction of the pivot axis of the rotary lock. In addition, this also results in a simplification of the clamping device and fewer individual parts. With its pressure surface facing the drawer, this presses against a front surface on the clamping element facing the panel. Due to the axial securing and support of the rotary bolt on the drawer, the pressure surface of the rotary bolt facing the drawer can exert a compressive force on the clamping element directed towards the drawer. This design also makes the drawer according to the invention with a clamping device extremely simple and inexpensive. The clamping device ultimately has only two individual elements, namely on the one hand the clamping element and on the other hand the twist lock mounted on the drawer side, both can be designed as very flat parts and also be designed as plastic arm parts which are extremely simple and above all cheap. Each clamping device according to the invention is therefore extremely narrow in the direction of the pivot axis, so that the space required for the invisible accommodation and thus the box front wall can be as narrow as possible. It is also advantageous that the front wall, viewed with the panel attached, is all around, that is, too

Rather, the aperture remains in this position, so that a single person afterwards, starting from a zero adjustment position in the height direction and / or in the lateral direction, the fine adjustment of the diaphragm floating and within the by a two-axis coordinate system spanned plane can make. According to the invention Training also creates the prerequisites for providing further advantageous training, e.g. those, as they result from DE-GM 77 35 252 and / nder of DE-OS 28 34 152.

An advantageous embodiment results from the claim 2. Such a lateral actuator in the form of an adjusting screw is particularly simple and inexpensive. It is Easily accessible from the outside and can be introduced by one alone without the need for special tools Screwdriver can be moved. It is therefore for a single person to fine-tune the attached diaphragm Quickly and easily possible, e.g. to bring the panel to the target position at one end area, then in the area of the other end must also be adjusted and set to target position 2U, then with a screwdriver and two j Using the handles on both sides of the drawer, actuate the actuator located there and thereby the breech lock in To move the aperture setting when the aperture is adjusted

Another advantageous embodiment contains the Claims 3, 4 and 5. In this way, the rotary latch added to the drawer side without great additional effort and held captive, and at the same time in the axial direction supported. Which are effective when tightening the clamping elements against the drawer by means of the rotary bolt Reaction forces are on the drawer side in the area of the Lock webs added.

Another advantageous embodiment contains claim 6, As a result, the Quarter-Turn with simple structural means and extremely low cost in the transverse direction, so radial, stored.

Another, particularly advantageous embodiment results in from claim 7. The definition made therein of increasing in the pivoting direction of the rotary latch for tensioning Slope means that the slope increases so that when pivoting the rotary lock for the purpose of Tension the clamping element increasingly more in the direction of the drawer and against the contact surfaces there is pressed. A design according to claim θ with wedge surfaces mentioned therein is advantageous. One particularly advantageous development to this includes claim 9. This design is particularly simple and cheap, as provided on the rotary latch and / or on the drawer side and / or in the area of the front surface of the clamping shoulder Wedge surfaces can be provided at the same time as the production of the respective part, e.g. during production can be molded on as a molded plastic part.

Another embodiment is given in claim 1.1, which is just as easy and cheap.

Further advantageous designs emerge from claims 14 and 15. The hook-like engagement according to claim 16 and the further designs according to claims 17-21 also lead to simplification the jig. Above all, they make it possible for the diaphragm to be displaced relative to one another when it is attached between the drawer and the cover is already fixed towards the bottom and can be released, suspecting the danger is that the diaphragm loosens or even falls down because due to the relative displacement between the front panel and the drawer, the clamping shoulders engage behind des Spannelemer.fces the rotary latch on the rear surface in the area of the pressure surfaces there. This happens like a hook, so that the cover is secured against further sliding down.

The drawer 10 shown in FIGS. 1 and 2 is in the exemplary embodiment designed as a one-piece injection-molded plastic body, which is designed double-walled at least in the area of each side wall 11; It goes without saying, that the drawer is made of wood and / or plastic and / or sheet metal or other suitable materials can. The bottom 12 of the drawer 10 is integral with the visible side wall 11, the other side wall, the rear wall, not shown, and the box front wall 13, on which a panel 14 is to be attached. The box front wall 13 generally has front side brackets on the left and right, each for the detachable and adjustable attachment of the

rich. Of these, only the left corner area IU can be seen in FIGS. 1 and 2. The panel 14 is fastened to the drawer 10 in each of these areas by means of a clamping device 15 there.

The front wall 13 has an inner wall 16 that is integral with the base 12 and is preferably at a distance from the latter approximately parallel outer wall 17 at least in the area of the ends on both sides, where in each case a jig l5 sits. The outer wall 17 has an approximately bayonet-like shape in the area of each clamping device 15 Breakthrough 16 on. This serves to hold parts of the clamping device 15.

Each clamping device 15 makes it possible, the front
Aperture 14 detachable, continuously adjustable and fixed to the
To attach the front wall 13 of the drawer 10. The clamping device 15 has a rotary bolt 20 which is held pivotably about its pivot axis 21. The pivot axis 21 extends approximately at right angles to the diaphragm 14.

A component of the clamping device 15 is also a clamping element 40 which is held in a non-rotatable manner with respect to the panel 14 and interacts with the rotary bolt 20. the
The interaction takes place in such a way that the clamping element 40 by pivoting the rotary switch 20 in the direction of the arrow 22 [Fig. 1,4] is applied with an axial clamping force,

- 23 -

the direction of action of which ^{points from the diaphragm 14 WB} g and is directed towards the inner wall 16. This axial tensioning force is generated by pressure surfaces 23 and 24 of the rotary bolt 20 which point in the direction of the pivot axis 21 towards the drawer 10, ie axial pressure surfaces 23 and 24.

There? Clamping element 40. has its own clamping surfaces 41 and 42, with which the clamping element 40 in the direction of the drawer and there against associated, drawer-side contact surfaces 43 or 44 can be addressed. The clamping element 40 is therefore from the rotary bolt 20, namely its upper pressure surface 23 and lower pressure surface 24, pulled away in the direction of the panel and towards the drawer 10 and thereby with the upper clamping surface 41 against the upper contact surface 43 and with the lower clamping surface 42 against the lower contact surface 44 pressed against the front wall 13.

The rotary latch 20 is held on the drawer 10 and on the drawer side mounted pivotably about the pivot axis 21. Most importantly, the rotary latch 20 is related to the drawer 10 axially secured and supported, as will be described in more detail later.

The pressure surface 23 and 24 of the rotary bolt 20 is arranged on the back surface 25 of the rotary bolt 20, that is to say on the side of the rotary bolt 20 facing away from the panel 14 and facing the front wall 13 of the drawer 10.

The contact surfaces 43 and 44 on the drawer side are seated a front wall part, in the embodiment shown and therefore only preferably on the outer surface of the front inner wall 16. The contact surfaces are 43 and 44 facing the back surface 25 and the aperture 14

Between the rear surface 25 of the rotary bolt 20 on the one hand and the contact surfaces 43, 44 on the inner wall 16 on the other hand an axial upper gap 45 and lower gap 46 are formed. Every gap is through that two aforementioned surfaces limited in the axial direction. The width of each gap 45, 46 measured in the direction of the pivot axis 21 can be changed by pivoting of the rotary bolt 20 can be reduced in size in the tensioning direction according to arrow 22 and in the opposite direction to arrow 22 and therefore Can be enlarged in the loosening direction. |

It can be seen that a pivoting movement of the rotary lock 20 in the direction of arrow 22 leads to its upper pressure surface 23 and lower pressure surface 24 on the rear surface 25

I can be brought closer in the axial direction to the upper contact surface 43 or »lower contact surface 44, so that the upper intermediate space 45 and the lower intermediate space 46 are thereby reduced. An opposing pivoting movement of the rotary bolt 20 leads to an increase in the distance between the above-mentioned surfaces and thus to an increase in the upper intermediate space 45 and lower intermediate space 46.

The tensioning element 40 is fixedly arranged on the rear side 47 of the panel 14. The back 47 is the one that goes to Drawers 10 indicates, namely to its front wall 13. fs The fixed attachment of the clamping element 40 is done either by means of schematically indicated dowels 48, 49 and / or by means of screws, not shown, which are provided by Reach through holes 50, 51 of the tensioning element 40 and screw them into the panel 14 from the rear side 47 are,

The tensioning element 40 has 45 and 48 for each intermediate space a clamping shoulder 52 or S3 engaging therein. The upper clamping shoulder 52 engages in the upper gap 4 £ 5 one, while the lower clamping shoulder S3 in the lower 2wi ~ §

height space 46 intervenes * The interventions seen in both J

; Clamping shoulders 52 and 53 from above, as can be seen from FIG is. The clamping shoulders 52, 53 carry the special clamping surfaces 41 and 42 of the clamping element, which are located on the The back of each clamping shoulder 52 and 53 are located, that is, on the side facing away from the panel 14 and facing the Varderwand 13 of the drawer 10 is facing.

In addition, each clamping shoulder 52, 53 carries a Varder surface 54 or 55 facing towards the panel 14, which for example essentially runs parallel to the rear clamping surface 41 and 42, respectively. When tensioning the rotating bolt 20 by pivoting in the direction of arrow 22, its upper pressure surface 23 presses axially and in the direction of the drawer against the front surface 54 of the upper clamping shoulder 52. Likewise, the lower pressure surface 24 of the rotary lock 20 presses you in the axial direction and towards the drawer IQ towards the lower front surface 55 dos lower clamping shoulder 53. As a result, clamping shoulders 52, 53 with their rear clamping surfaces 41 or 42 firmly against the associated contact surface on the drawer side 43 or 44 pressed on, whereby the panel 14 is firmly attached to the front wall 13 of a drawer 10. This fastening is done invisibly and with extremely simple means. The low one is particularly advantageous Effort that each clamping device 15 makes necessary. The small space requirement has also proven to be advantageous proved that each clamping device 15 has, not only seen in the direction of the pivot axis 21, but moreover also seen within the plane of the diaphragm 14, namely there with respect to the height and width directions given projection of each clamping device 15.

It can be seen that the tensile force applied by the rotary bolt 20 during its pivoting movement in the tensioning direction as Clamping force applied to the drawer 10 acts on the clamping element 40 and with its clamping surfaces 41, 42 axially against the drawer-side contact surfaces 43 or * 44 presses *

The rotary latch 20 is a laterally arranged actuator in farm z. B. assigned to a screw 60. The screw is held axially movable in the material of the drawer IG, namely screwed. The screw 60 is used for adjustment purposes freely accessible from the outside of the drawer 20. Man only needs a screwdriver into the indicated hole 61 in the area of the left side wall 11 of to intervene from the outside. As Fig. 1 shows, the screw is seated BO at a radial distance from the pivot axis 21, the end of the screw 60 at the upper end region on the left in FIG. 1 of the rotary bolt 20 for its pivoting actuation in the tensioning direction according to arrow 22 as well as in the opposite direction Attacking direction of release. It can then be sufficient if the screw 60 with its free end only against the rotary bolt 20 abuts. Instead, the screw can also end not only in the pressure direction but also be coupled to the rotary latch 20 in the pulling direction, but movably at the same time. Then it causes an unscrewing of the screw 60 by means of tensile force, the rotary lock 20 is pivoted against the direction of the arrow 22.

The rotary latch 20 has essentially the shape of a flat tab. It consists of a one-piece plastic molded part but can instead also consist of sheet metal, wood or other suitable material.

.Fig · 1 shows that the opening Iß in the outer wall 17 is designed like a bayonet. It has a contour determined by the outline of the rotary bolt 2G, which is chosen so that the rotary bolt 20 can be taken as a separate part, as shown in FIG. 4, and then referenced, for example, in a 45 ° pivot position on the pivot axis 21, can be inserted into the opening 18, in the direction of the inner wall 16 so deep that the bayonet webs 26 and 27 of the rotary bolt 20 are beyond the outer wall 17. A pivoting of the rotating bolt in the direction of arrow 22 results in the two bayonet bars 26 and 27 engaging behind the associated locking bars 28 and 29 provided on the edge of the opening 18, so that the rotating bolt 20 moves into its captive holding position. It is now seated captively on the front wall 13 within the opening 18.

The panel 14, which has been provided with the clamping elements 40 in the area, for example, at both ends, can then be approached to the front wall 13 of the drawer 10, the hook-shaped clamping shoulders 52 and 53 of each clamping element 40 having the associated access openings 35 and 36 in the rotary bolt 20 take action. By relative displacement between the cover 40 and the drawer 10 downwards, the clamping shoulders 52 and 53 hook behind the rotary bolt 20 and there come into abutment contact with the respective rear pressure surface 23 or 24.3e after the pivoted position of the rotary bolt 20 is then a sufficiently large static friction in the area of all mutually effective surfaces of the clamping device 15 is available that the panel 14 can be finely adjusted and set floating up and / or down and / or left and / or right, for example, in the area of the left barren Sndes right of the diaphragm 14 ülustierläge restored versehsben wipd and lost, the aperture 1st finely adjusted, go dia Sehraube 60 is wide hineingedrehfc däduröh and the rotary latch 20 in Pfsilriehtung 22 for tensioning

panned. Swivel movements with a very small amount are sufficient Swivel angle already from. Due to the helical shape of the bayonet webs 26, 27 of the rotary lock 20, this the rotary bolt 20, axially supported on the locking webs 2B, 29, further in the direction of the inner wall 16 of the drawer 10 moved and forced. This has the consequence that over the upper pressure surface 23 and lower pressure surface 24 of the rotary bolt 20 on the associated front surface 54 ftzw. 55 of the clamping shoulder 52 or 53 an axial pressure to the drawer is exercised, whereby the rear clamping surface 41 or 42 is even more firmly against the drawer-side, associated contact surface 43 or 44 is pressed. This has a tight tightening of the screen 14 against the front wall 13 of the drawer 10 result.

In Fig. 1 is indicated by dashed lines that an easily breakable nose 37 is formed on the rotary latch, which is attached to the lower edge of the upper pass-through opening 35, there approximately in the middle, sits and protrudes upward into the access opening 35. The nose 37 serves as a stop. Associated with the nose 37 is a stop surface on the clamping element 40, specifically on the upper clamping shoulder 52. The one there The stop surface is through the underside of the upper U-leg 56 self-formed. The nose 37 defines when the panel 14 is attached and the pressure surfaces are gripped behind 23, 24 of the rotary bolt 20 through the associated clamping shoulders 52 and 53 with shift all the way down an initial position, from which a fine adjustment of the diaphragm 14 can then take place. So this starting point has been reached, when the panel 14 is pushed down so far that the underside of the upper U-leg 56 on the upright Nose 37 pushes open. If the nose 37 is in the way, 2.B * because the diaphragm 14 is pushed down further must be> so the nose 37 2. B. van hand can easily be removed " be broken · Bs it goes without saying that the ratios can also be reversed, i.e. the stop in the form of the Nose 37 can sit on the clamping element 40 and the associated Ansehlag-fläeha then through a surface at the edge of the turning
