Description

The present invention relates to a shelf according to the preamble of claim 1 or a rail holder according to the preamble of claim 15.

Such shelves have been known for a long time. They often have rows of holes that are attached to shelf cheeks, for example shelf walls. The shelf cheeks can either be designed as solid walls or consist of two spars, a front and a rear spar.

The rows of holes can be integrated into the shelf cheeks or the bars or attached to them. In the latter case, they often consist of sheet metal strips that are attached to the shelf cheeks. Any shelf elements such as shelves, pull-outs, drawers or telescopic rails can be attached to the holes in the rows of holes.

The holes in the rows of holes are formed in a predetermined grid dimension. This makes it possible to attach the shelf elements at any height and to change the desired height later if necessary. For this purpose, the shelf elements have brackets or pins or other suitable connecting elements which extend into the holes in the rows of holes and support the shelf element in question.

Typically, a shelf element is stored in at least four places, i.e. left front, left rear, right front and right rear.

Each bearing point can be formed by the engagement of the connecting element in the hole in question, or possibly also by engagement in two holes arranged one above the other. It has also become known to form the connecting elements not directly on the shelf element, but on an adapter, which in turn is connected to the shelf element.

An example of the storage of telescopic rails on rows of holes is that from DE 88 02 388 U1 well-known shelf. This shelf has an adapter for telescopic rails, which can be inserted into rows of holes using brackets. A front row of holes and a rear row of holes are provided, which are formed on a front spar and a rear spar, respectively.

The clip attached to the rear of the telescopic rail or the adapter there can be inserted into a rear hole from the front. The clip attached to the front of the telescopic rail can be inserted from above into the front hole on the front spar, i.e. the front row of holes. However, this design has not established itself on the market. One problem was the play in the mounting of the adapter, on the one hand on the telescopic rail and on the other hand on the row of holes.

Another example of a shelving system with rows of holes arranged in a grid is the one from the DE 19 96 191 U1 known solution. It has also been suggested that a To provide a bearing point through two adjacent holes in a row of holes, into which each pin engages. With double storage at each bearing point, stability can be significantly increased. However, it has been shown that in certain stress situations, long-term stability in particular can be improved.

The invention is therefore based on the object of creating a shelf according to the preamble of claim 1 or a rail holder according to the preamble of claim 15, which show improved long-term stability under different load situations.

This object is achieved according to the invention by an object according to claim 1 or claim 15. Advantageous further developments result from the subclaims.

According to a first aspect, this object is achieved by a shelf, with rows of holes in shelf cheeks, in particular formed by a front and a rear spar, and with pull-out rails, which extend essentially horizontally along a shelf cheek, in particular from a front spar to a rear spar , extend and are mounted on this via a front rail holder and via a rear rail holder, with an upper and a lower hook pin being formed on each rail holder, which are intended for engagement in holes in the rows of holes and engage behind the wall areas adjacent to the holes, in particular spar wall areas , and wherein the upper hook pin of the rear rail holder points upward, characterized in that the lower hook pin of the rear rail holder points upward.

In a technically advantageous embodiment of the shelf, the hooks of the upper hook pins are longer than those of the lower ones.

In a further technically advantageous embodiment of the shelf, the pin areas of the hook pins extend into the holes and pass through them and the hooks of the hook pins extend distally from the pin areas.

In a further technically advantageous embodiment of the shelf, the hooks end on hook end faces and the pin areas each have pin counter surfaces opposite the hooks and in the case of the lower hook pins the distance between the end face and the counter surface is smaller than the diameter of the holes.

In a further technically advantageous embodiment of the shelf, the distance between the end face and the counter surface of the upper hook pins is greater than the diameter of the holes.

In a further technically advantageous embodiment of the shelf, the distance between the hook pins of a rail holder corresponds to the distance between adjacent holes in the rows of holes and the hook pins of a rail holder can be fastened into the adjacent holes by inserting the upper hook pins, lifting the rail holders and inserting the lower hook pins into the bars .

In a further technically advantageous embodiment of the shelf, the upper hook pin of the front rail holder points upwards.

In a further technically advantageous embodiment of the shelf, the lower hook pin of the front rail holder points downwards.

In a further technically advantageous embodiment of the shelf, the pin area of the lower hook pin has a play of between 3% and 20%, in particular between 6% and 13% and particularly preferably around 9Ω, of its diameter relative to the hole.

In a further technically advantageous embodiment of the shelf, the vertical projection dimension of the hook of the lower hook pin relative to the pin area is between 2% and 18%, in particular between 5% and 12% and particularly preferably around 8%, of the diameter of the pin area.

In a further technically advantageous embodiment of the shelf, a vertically downwardly extending slot is formed between the lower hook of the rear rail holder and a contact surface for the contact of the rail holder on the outside of the spar, the width of which essentially corresponds to the thickness of the spar wall.

In a further technically advantageous embodiment of the shelf, the slot tapers downwards with a cone angle between 1 degree and 20 degrees.

In a further technically advantageous embodiment of the shelf, the lower hook pin extends at the height of a support leg supporting the pull-out rail and/or the rail holder has an L-shaped cross section.

In a further technically advantageous embodiment of the shelf, the pull-out rail is designed as a multi-part telescopic rail, the extension length of which corresponds to or is greater than the distance between the front and rear bars.

In a further technically advantageous embodiment of the shelf, a right pull-out rail supports a pull-out on the right, and a left one on the left, and the associated rail holders are designed to be mirror-symmetrical to one another.

In a further technically advantageous embodiment of the shelf, the pull-out can be loaded with a weight that corresponds to a multiple, in particular at least six times, of the torsional resistance force of each pull-out rail in the unassembled state, which it opposes to a torsional force.

According to a second aspect, this object is achieved by a rail holder, on which an upper and a lower hook pin are formed, which are intended for engagement in holes in rows of holes and to engage behind the holes in wall areas adjacent to the holes, in particular spar wall areas, and wherein the upper hook pin of the rail holder points upwards, in which the lower hook pin of the rail holder points upwards.

According to the invention, a shelf is provided which can be equipped with pull-out rails which are mounted in a special way on the shelf cheeks. For this purpose, the shelf has vertical rows of holes on the shelf cheeks, which have holes in a predetermined grid size. According to the invention, the pull-out rails can also be stored in the holes Any other shelf elements such as shelves, drawers, simple pull-outs, etc.

The shelf cheeks stand on the floor in a manner known per se. They can, for example, be formed by solid walls or each have individual spars. The rows of holes can be integrated into these, or formed into strips of material that extend on the shelf cheeks and are attached to them.

In a manner known per se, a front and a rear row of holes are provided, and when using spars, a front and a rear spar. A shelf, a drawer, a telescopic pull-out and similar shelf elements are typically stored on both sides. Accordingly, rails, rail holders, rows of holes, etc. are designed on both sides of the shelf element, i.e. on its right and left sides, usually in mirror images of one another. For the sake of simplicity, only one page is considered here and in the following.

To support the pull-out rail of a telescopic pull-out, according to the invention a rail holder is mounted at the front and rear of the shelf cheek, in the case of the realization of bars on the front and on the rear bar. According to the invention, each rail holder is equipped with two vertically spaced hook pins. The spacing of these is chosen so that in the assembled state, the upper hook pin engages in an upper hole in the row of holes, and the lower hook pin engages in the hole underneath the upper hole adjacent to it. Hook tenons have the advantage of extending through one hole and on the wall of the shelf or shelf stringer on the other side of the hole. This makes storage without play possible, provided there is an appropriate fit.

Hook tenons consist of hooks that extend across tenon areas. The hook pin is attached to the rail holder in such a way that its pin area extends laterally, i.e. essentially horizontally. The hook of the hook pin extends upwards or downwards from the pin area, i.e. essentially vertically. The pin area is designed so that it passes through a hole in the row of holes. For round holes it is also preferably round. It is only about as long as the horizontal extent of the hole, i.e. the wall thickness of the shelf cheek, e.g. a rail.

Due to this configuration, the hook of the hook pin rests on the back of the shelf cheek, and the pull-out rail is supported on the shelf cheek without play in the horizontal direction.

According to the invention, 2 hook pins are formed on each rail holder, an upper and a lower one. The upper hook pin of the rear rail holder points upwards, and according to the invention, the lower hook pin of the rear rail holder also points upwards. This design has the special effect that when the telescopic extension is loaded in the extended state, both hook pins are pressed upwards in their hole in the row of holes. The hook of the lower hook pin then also engages behind the shelf cheek or the spar wall in which the hook pin is guided. The rail holder is thereby forced into an upright position resting against the shelf cheek.

This has the following special effect:
When the telescopic extension is loaded when extended, the telescopic rail acts like a two-armed lever that is mounted on the front rail holder. The power arm, i.e. the part of the rail between the front and rear rail holder, tends to twist, as it were, to avoid the force exerted.

Without the measure according to the invention, i.e. a lower rear hook pin that points upwards, the telescopic rail could twist in on itself and the lower hook pin could slip out of its anchoring, which led to the failure of the telescopic extension. In contrast, according to the invention, the pull-out rail is always guided closely to the shelf cheek, even in the rear area. There it rests against the rail or shelf cheek with a holder contact area. This also applies when the telescopic extension is extended and loaded.

In contrast, in the case of the front rail holder, the hook of the lower hook pin is preferably directed downwards and the hook of the upper hook pin is directed upwards. When the telescopic extension is loaded, the front rail holder supports almost the entire weight of the telescopic extension, and the lower hook pin absorbs a large part of it. Its downward hook securely grips the spar wall.

In an advantageous embodiment, the hooks of the lower hook pins are shorter than those of the upper ones. For insertion into the holes of the rows of holes, with the telescopic rail tilted, the upper hook pin is first inserted in a manner known per se and then the lower one. This will make both the The front and rear rail holders are each brought into contact with the shelf cheek with its holder contact surface.

When the telescopic cable is pushed in, its weight rests essentially evenly on its 4 rail holders. This also puts a downward force on the rear rail holders. This can push the lower hook pin of the rear rail holder down so far that its hook no longer engages behind the rail wall, but is at the level of its hole. However, this "release" is harmless because the load of the extension tries to push the lower hook pin outwards, i.e. towards the spar, but it cannot escape due to the effect of the holder contact surface.

The surprising result is that the - comparatively simple - measure according to the invention of allowing the lower rear hook pin with its hook to point upwards ensures safe and long-lasting storage and guidance of a telescopic-guided pull-out. This also resists torsional forces in that if the telescopic rail twists, this is compensated for by the special design of the rear rail holder.

In an advantageous embodiment, it is provided that the rail holder has a bearing leg with the hook pins and a support leg supporting the pull-out rail and that a contact surface, possibly provided with an opening, is formed on the bearing leg for the system on the outside of the spar, the distance from which the hook, viewed in a vertical projection, corresponds to the wall thickness of the spar wall.

Further details, advantages and features result from the following description of an exemplary embodiment of the invention based on the drawing.

Out of Fig. 1 A shelf 10 can be seen in a small section. The shelf 10 has 4 spars, of which a front spar 12 Fig. 1 is visible. The front spar 12 is spaced from a rear spar 14 and stands on the ground. Both bars 12 and 14 form a shelf cheek 15, as shown Fig. 1 a left shelf cheek 15 des Shelves 10. The bars can be connected to one another, for example at the top and bottom, in any manner known per se, for example by a connecting strut, not shown, for example with the help of screw connections.

The shelf 10 can be part of a shelving system in which several individual shelves are connected to one another. The shelves can be equipped with any number of different shelf elements. The shelf 10 considered here is intended for a telescopic pull-out at the location shown, of which a left pull-out rail 22 is shown in the figures.

The spar 12 and the spar 14 each have a plurality of holes 16 which are arranged one above the other, in a grid dimension, i.e. at the same distance from one another. In this respect, a front row of holes 18 is formed on the front spar 12, and a rear row of holes 20 is formed on the rear spar 12.

In the in Fig. 1 In the position shown, the pull-out rail 22 is not yet hooked into holes 16 in the rows of holes 18 and 20. A front rail holder 24 and a rear rail holder 26 are intended for hanging. The rail holders 24 and 26 are an integral part of the pull-out rail 22.

The front rail holder 24 has two hook pins on its side facing the row of holes 18, namely an upper hook pin 28 and a lower hook pin 30. The rear rail holder 26 also has two hook pins, namely an upper hook pin 32 and a lower hook pin 34. This is e.g. from Fig. 5 visible.

The hook pins 28 to 34 have different orientations and designs. The hook pins 28, 32 and 34 point upward and the hook pin 30 points downward. Furthermore, the upper hook pins 28 and 32 are slightly longer than the lower hook pins 30 and 34. Each of the hook pins consists of a better one Figures 7 and 8th visible pin area 36 and a hook 38.

The distance from the top of the pin portion 36 of the upper hook pin 28 to the lower end of the hook 38 of the lower hook pin 30 on the front rail holder 24 is slightly less than the distance from the lower edge of the hole 16 intended for engagement of the lower hook pin 30 Upper edge of the hole 16 intended for engagement of the upper hook pin 28.

The distance from the top of the pin portion 36 of the upper hook pin 32 to the lower end of the pin portion 36 of the lower hook pin 34 on the rear rail holder 26 is slightly less than the distance from the lower edge of the hole 16 intended for engagement of the lower hook pin 34 Upper edge of the hole 16 intended for engagement of the upper hook pin 32.

The distance of the upper end surface of the hook 38 of the upper hook pin 28 to the underside of the pin portion 36 of the lower hook pin 30 on the front rail holder 24 is slightly larger than the distance of the lower edge of the hole 16 intended for engagement of the lower hook pin 30 Upper edge of the hole 16 intended for engagement of the upper hook pin 28.

The distance of the upper end surface of the hook 38 of the upper hook pin 32 to the underside of the pin portion 36 of the lower hook pin 34 on the rear rail holder 26 is slightly larger than the distance of the lower edge of the hole 16 intended for engagement of the lower hook pin 34 Upper edge of the hole 16 intended for engagement of the upper hook pin 32.

With the dimensioning rules in the 4 previous paragraphs it is achieved that the pull-out rail 22 in the raised state from the tilted position according to Fig. 2 into the position resting on the bars 12 and 14 Fig. 3 can be inserted and then lowered, and that in this adjacent, lowered position the pull-out rail 22 is locked against accidentally falling out.

In the lowered position, the hooks 38 of the hook pins 28, 30 and 32 engage behind the spar wall. The pull-out rail cannot be separated from the bars 12 and 14 either by tilting or pivoting or by pulling it straight out. What is involved with the hook 38 of the lower hook pin 34 of the rear rail holder 26 can also be found in the explanation below.

Out of Fig. 4 the pull-out rail 22 can be seen schematically in the partially extended state. A fixed part 40 can be seen to which the rail holders 24 and 26 are attached. A first movable part 42 is mounted on this, and a second movable part 44 is mounted on this. A drawer or any other pull-out element such as a board is mounted on the second movable part 44.

When fully extended, this extends together with the second movable part 24 in front of the front bar 12. In this state, but also in the in Fig. 4 In the state shown, the pull-out rail acts like a two-sided lever, with the second movable part 44 as a load arm and the fixed part 40 as a power arm. The lever bearing point is then the front rail holder 24.

When a weight is placed on the extension element, the weight force is translated into an upward force via this two-sided lever. This force acts upward on the rear rail holder 26.

In this state, according to the invention, the hook 38 of the lower hook pin 34 of the rear rail holder 26 is used: especially when the weight force is so great that it could cause the pull-out rail 22 to deflect due to twisting, the hook 38 of the hook pin 34 prevents twisting . The pull-out rail 22 has a significantly higher section modulus in the vertical direction than in the horizontal direction. When left untwisted, it can absorb considerable loads, while it easily fails when twisted.

In particular, the twisting leads to wear of the guide elements that are provided internally in the pull-out rail 22. These can, for example, have balls or rollers that run on rolling bearing tracks. The rolling bearing tracks can, for example, have a semicircular cross-section and would be expanded, so to speak, by rotating the extension rails, so that safe guidance by the guide elements would no longer be guaranteed.

In this respect, according to the invention, the long-term stability of the shelf with telescopic extension is significantly improved, namely through the simple action of the hook 38 of the hook pin 34 of the rear rail holder 26. This hook points upwards, so that it acts on the rear rail holder 26 under the upward force described above engages behind the wall of the spar 14 and holds the rail holder 26 securely and, above all, upright on the rear spar 14 even in this loaded position.

This position is from the Figures 5a and 5b visible. In Figure 5a the rear rail holder 26 is shown in the mounted position in which the weight of the telescopic extension pushes it upwards. Out of Figure 5b It can be seen that beforehand, i.e. without the upward force, it can easily be inserted into the hole 16 in the tilted state with the hook 38 of the upper hook pin 32, and then can be pivoted so that the hook pin 34 covers the hole 16 underneath can pass through.

Out of Fig. 6 The pull-out rail with the fixed part 40, the rear rail holder 26 and the front rail holder 24 can be seen in perspective. The position and arrangement of the hook pins 28, 30, 32 and 34 are also shown.

Out of Fig. 7 it can be seen how the front rail holder 24 passes through holes 16 of the spar 12. Each hook pin 28 and 30 has a pin area 36 and a hook 38. The hook 38 of the upper hook pin 28 is longer than the downward-pointing hook 38 of the lower hook pin 30. The pin areas 36 are mounted in the holes 16 with some play.

Out of Fig. 8 It can be seen how the rear rail holder 26 is constructed in section. The hook pins 32 and 34 pass through the holes 16 with their pin areas 36, and the hooks 38 engage behind the wall 50 of the spar. The rail holder 26 rests with a contact surface 52 on the wall 50 of the spar. When an upward force acts on the rail holder 26, both hooks 38 of the hook pins 32 and 34 extend behind the wall 50.

The more precise design of the rear rail holder 26 is out Fig. 9 visible. It can be seen that the pin areas 36 are guided in the holes 16 with play. The distance between the upper end region 56 of the lower hook 38 and the underside 58 of the pin region 36 of the lower hook pin 34 is so small that the hook pin 34 can pass through the hole 16.

However, this does not apply to the upper hook pin 32. Therefore, the upper hook pin 32 can only be inserted into its associated hole 16 when tilted. However, if a force acts upwards on the rail holder 26, both hook pins 32 and 34 lock, so that secure storage is guaranteed.
