Fastening device for a plate, in particular a table or worktop, to an OestelX or to a wall

The invention relates to a fastening device for a plate, in particular a table or worktop, to a frame or a wall according to the preamble of claim 1.

In this known fastening device (DB-GK 88 12 473), the support is formed by a hollow profile part that has longitudinal grooves at its corners that extend to the interior of the support and into which connecting parts engage, with which a cable guide element, a cabinet element or a console can be attached to the support. For fastening to the support, the console has a hook-shaped connecting part with which it is hooked into one of the longitudinal grooves of the support. Another hook-shaped connecting part is inserted into the opposite longitudinal groove of the support and is then screwed to the console. In another embodiment, the console is connected to the support via a bearing element and several spacer elements. With these fastening devices, a

A secure and firm connection between the console and the support is not guaranteed, so that there is a risk that the consoles may perform unintended relative movements with respect to the support.

The invention is based on the object of designing the generic fastening device in such a way that the console can be held absolutely firmly on the carrier regardless of manufacturing tolerances.

This object is achieved in the generic fastening device according to the invention with the characterizing features of claim 1.

In the fastening device according to the invention, the console is clamped to the support so that it is held absolutely firmly and unadjustably on the support. As a result of the clamping, the tolerances that inevitably occur during the manufacture of the console and/or the support are reliably compensated so that the console is always held immovably on the support.

In an embodiment according to claim 2, the connecting part is already provided on the console, thus does not form a part that has to be additionally attached to the console. This considerably simplifies the assembly of the console.

The connecting part according to claim 3 is advantageous

pivotable on the console so that it can be easily mounted or dismounted in the

Locking division or can be adjusted to the release division.

G 89 141 - 7 - 19.12.1989

An advantageous design of the console results |

according to claim 4. Between the two supporting legs

the pivoting connecting part is protected under ge- '-

brought.

An advantageous design of the connecting part is provided according to claim 5. With the outward-facing hook, the connecting part can be easily hooked into a corresponding form-locking means of the carrier. Such a form-locking means is, according to claim 6, a groove in the carrier. It advantageously extends over the entire length of the carrier, so that the console can be brought into any desired installation position along the carrier.

According to claim 7, the connecting part is advantageously connected in a form-fitting manner to the axle bolt, with which the connecting part can be pivoted or rotated on the handles of the console.

A preferred design of the axle bolt is given in claim 8. The square middle piece provides the positive connection to the connecting part, while the cylindrical pins form the bearing pins of the axle bolt, with which it is mounted in the bearing openings of the support -

leg of the console is rotatably mounted. f

Ü The middle part of the axle bolt forms according to claim 9 also a bearing for the adjusting part with which the connecting part can be mounted during assembly and disassembly

into the release position or into the lock position- >- _;

G 89 141 - 8 - 19.12.1989

can be adjusted easily.

The axis of the threaded hole in the middle section of the axle bolt is perpendicular to the axis of rotation of the axle bolt according to claim 10. This causes the connecting piece to be guided in the direction of the axle β β of the wind deflection.

Assembly and disassembly adjusted.

The connecting part is also clamped to the support in accordance with claim 11 when the console is mounted/ so that any play that may exist is reliably compensated.

Preferably, the carrier engages with the edge section in the recess of the hook of the connecting part. This ensures that the connecting part is perfectly secured against pivoting. This also ensures that the console is attached to the carrier without play.

In order for the connecting part to be able to be pivoted, it is preferably adjusted in accordance with claim 13 so that the web connecting the legs rests on the middle part of the axle bolt. This ensures that pivoting of the connecting part is only possible in this position, so that the connecting part cannot be inadvertently pivoted from the locking position into the release position.

Claim 14 specifies a preferred embodiment of the support, which has a further groove for hanging the further connecting part of the console.

6 89 141 - 9 - 19.12.1989

In order to obtain a structurally simple design of the carrier, the grooves are provided according to claim 15 on opposite sides of the carrier.

Preferably firmly connected to the console or made in one piece with it. This means that this additional connection point does not have to be laboriously attached to the console. This makes mounting the console on the carrier much easier.

Claim 17 specifies a particularly simple design of the console.

If the bracket rests with the edges of its support legs on the long side of the beam in accordance with claim 18, it is optimally supported on the beam. In particular, the hook-shaped connecting parts are not subjected to excessive stress when the bracket is loaded. The forces are largely directed into the beam via the edges of the support legs, so that the hook-shaped connecting parts themselves are largely relieved of stress.

Further features of the invention emerge from the further claims, the description and the drawings.

The invention is explained in more detail using an embodiment shown in the drawings.

in bottom view and partly in section a part of the fastening device according to Fig. 3.

The work table according to Fig. 1 has a table or worktop 2 arranged on a base frame 1. Its underside 3 rests on two brackets that are spaced apart from one another. They are attached to a cross member 5 of the base frame 1. The brackets 4, together with the cross member 5, form a fastening device with which the plate 2 is attached to the base frame 1.

In the embodiment according to Fig. 2, the plate 2a is attached to a wall 6 via brackets 4a and one or two supports 5a. The brackets 4a are designed in the same way as the brackets 4, which will be explained in more detail with reference to Figs. 3 and 4. The support 5a is also designed essentially the same way as the support 5 according to Fig. 1. However, it can also be formed by two support parts, each of which is assigned to a bracket and attached to the wall 6.

G 89 141 - 11 - 19.12.1989

The only important thing is that these supports, like support 5, have an upper and lower groove for hanging the brackets.

The support 5 is preferably a hollow profile part with an angular, preferably rectangular cross-section, which extends almost over the entire length of the plate 2. The support is attached to the frame 1 in a manner not shown in detail. It has a longitudinal groove 8 and 9 on its top and bottom sides 6 and 7 (Fig. 3). They are designed identically and arranged centrally, so that edge sections 10 to 13 of approximately the same width are formed on both sides of the grooves 8, 9.

The brackets 4, of which only one is shown in the drawings, are of the same design and have two plate-like support legs 18 and 19 that are congruent and spaced apart from one another. They essentially have the shape of a right-angled triangle and are arranged upright so that they rest against the underside 3 of the plate 2 with their one plate edge 4', which adjoins the base of the support legs at an acute angle. The two support legs 18, 19 of the bracket 4 can be connected to one another along the edge 4' by one or more cross pieces, for example welded.

As shown in Fig. 3 and 4, the support legs 18, from the cross member S are tapered towards their free ends 21. The wider other ends 22 and 23 (Fig. 4) rest with their upwardly extending edges 24 on one long side 25 of the cross member S.

G 89 141 - 12 - 19.12.1989

The support legs 18, 19 have on their upper, beam- side , 24 circumferential projections 16, 16' which form hook-shaped suspension parts for the support legs. The suspension parts 16, 16' protrude with their hook ends 26, 26' into the groove 8 on the upper side 6 of the cross member 5.

In the lower edge area 27 of the support legs 18, 13, at a distance from the edge 24 and the lower leg edge 28, there are circular plug openings 29, 30 (Fig. 4) that are aligned with one another, into each of which a cylindrical plug projection 31, 32 of an axle bolt 33 projects. The axle bolt 33 is rotatably mounted in the support legs 18, 19 with the plug projections 31, 32. In its middle section 34 between the plug projections 31, 32, the axle bolt has a rectangular, preferably square, outline. The slide piece 34 has a centrally arranged threaded hole, the axis of which runs perpendicular to the axis of rotation 36 of the plug projections 31, 32. The threaded hole 35 is penetrated by a threaded pin 37 with which a connecting part 17 can be adjusted.

The connecting part 17 has a plate-like U-shaped base body, the legs 38, 38' of which point downwards in the assembly position according to Fig. 3. An L-shaped hook part 39 is connected to the free end of one leg 38, which, in the securing position of the connecting part 17, projects with its hook end 40 into the groove 9 in the underside 7 of the carrier (Fig. 3).

The distance between the support legs 18/ 19 corresponds

6 89 141 - 13 - 19.12.1989

the thickness of the middle piece 34 of the axle bolt 33, over which the lugs 31, 32 protrude axially. The connecting part 17 has a thickness that corresponds to the distance between the support legs 18, 19, so that the connecting part 17 can be easily pivoted between the support legs 18, 19 and is guided perfectly on the facing inner sides of the support legs. In the assembled position, the connecting part 17 thus rests with its outer sides on the inner side of the support handles 18, 19.

The front binding part 17 has an epic, its legs 38, 38 a slit 41 with boundary walls 42 to 44 running at right angles to each other. Halfway along the length, the longitudinal boundary walls 42 and 43 are set inwards in a shoulder-like manner, so that the slit 41 consists of a wider slit cut 46 and a narrower slit section 45, which opens into the outer edge of the binding part 17.

The middle part of the axle bolt 33, which has the same width as the slot section 46, is located in the wider slot section 46. As a result, the connecting part 17 with its longitudinal boundary walls 42 and 43 lies flat against the parallel outer sides of the middle part 34, whereby the connecting part 17 is positively connected to the axle bolt 33 in the direction of rotation.

The length of the threaded pin 37 in the example is approximately equal to the slot length. As Fig. 3 and 4 further show, the legs 38 and 38' of the connecting parts 17 are relatively wide. They are preferably wider than

G 89 141 - 14 - 19.12.1989

the clear width of the slot section 46. The hook part 39 also has approximately the same width in the area of its section running perpendicular to the leg 38 as this, whereby the connecting part 17 has a high foraistability

% and stiffness. It can therefore also be relatively

absorb high forces perfectly. The hook end 40 is significantly narrower than the rest of the connecting part 17. Preferably, it is designed in the same way as the hook ends 26, 26' of the connecting parts 16, 16'. The width of the connecting parts 16, 16', 17 is only about half the clear width of the grooves 8, 9 of the carrier 5, preferably smaller than half the clear width of the grooves.

Between the hook end 40 and the leg 38, a recess 15 is formed, into which the carrier 5 projects with its edge section 12 in a form-fitting manner when the bracket 4 is mounted. Between the hook ends 26, 26' of the support legs 18, 19 and the edges 24, recesses 14 are formed, into which the edge section 10 of the cross member 5 engages when the bracket 4 is mounted.

The outer edge 48 of the connecting part 17 runs semicircularly in the area between the legs 38, 38'. This allows the connecting part to be pivoted about the axis of rotation 36 during assembly, as will be explained below.

For mounting and fastening to the carrier 5, the console

5. The width of the edge section 10 of the support 5 corresponds to the width of the recess 14, so that the console with the edges 24 of its support legs 18, 19 rests against the long side 25 of the support 5. The hook ends

26, 26' are spaced from the bottom of the groove 8 in the suspended position, while the support legs 18, 19 rest with the bottom of the recesses 14 on the edge section 10 (Fig. 3). The bracket 4 is thus aligned with respect to the support S.

At this stage of assembly, the threaded pin 37 is screwed back into the axle bolt 33 so far that the connecting part 17 with the boundary wall 44 rests flat on the center piece 34 of the axle bolt 33. The semicircular outer edge 48 of the connecting part 17 then lies, as seen in side view according to Fig. 3, on a circle around the axis of rotation 36 of the axle bolt 33. The radius of this circle in this case corresponds to the distance between the axis of rotation 36 and the long side 25 of the support 5. This makes it possible to rotate the connecting part 17 in its lowered position around the axis 36 clockwise into a release position. As soon as the bracket 4 has been hooked into the groove 8 of the support 5 in the manner described, the connecting part 17 is pivoted counterclockwise. As a result of the positive connection between the connecting part 17 and the middle piece 34 in the swivel direction, the axle bolt 33 is rotated, whereby the cylindrical plug-in projections 31, 32 are rotated in the bearing openings 29, 30 of the support legs 18, 19. Since the connecting part 17 projects downwards over the support legs 18, 19, it can be easily grasped and swiveled. As soon as the connecting part 17 has been swiveled back, the easily accessible threaded pin 37 is screwed back. Since the connecting part 17 rests on the threaded pin 37 with its boundary wall 44, the connecting part 17 is taken along when the threaded pin is screwed back.

until it reaches its locking or locking position according to Fig. 3, in which the connecting part 17 rests along its length with the leg 38 on the long side 25 of the support 5. In this, the edge section 12 of the support 5 rests on the bottom of the recess 15, the width of which corresponds to the width of the edge section 12. With the connecting part 17, the console 4 can be clamped to the support 5 transversely to its longitudinal direction, so that it is held firmly on the support without play.

As long as the connecting part 17 is not yet clamped against the support 5, the bracket 4 can be moved along the support 5 into the desired position.

The bracket 4 can also be attached to the opposite side of the support 5 in the manner described. As the width of the hook ends 26, 26', 40 is smaller than half the width of the grooves 8, 9, two brackets can also be attached to the support 5 at the same height, protruding from the support in opposite directions. The support 5 itself has an extremely simple structural design and enables the bracket 4 to be attached with absolutely no play.

In another embodiment, the carrier 5, 5a has no grooves. In this case, the connecting parts 16, 16', 17 engage around the carrier so that the hook ends 26, 26', 40 rest on the carrier side opposite the carrier side 25. The brackets 4, 4a can then be clamped to the carrier in the same way as in the described embodiment.

The grooves 8, 9 of the carrier 5, 5a can be designed such that

- 17 -

6 89 141 - 17 - 19.12.1989

that their side wall facing the brackets 4, 4a runs upwards in the clamping direction. The hook ends 26, 26', 40 have corresponding slanted surfaces with which they rest against the slanted side walls. The slanted surfaces enable tolerances to be compensated without affecting the clamping effect and the load-bearing capacity of the bracket.
