The supporting element is characterized in that the hook has a T-shaped design with a web (22, 42) and two projecting limbs (21, 23, 41, 42), and the length of the hook is greater than that of the recess in the vertical support.

Description

Support element with a T-shaped hook

The invention relates to a support element for a shelf for hanging on a support according to the preamble of claims 1, 5 and 7.

Known horizontal supports for shelves have one or more hooks at one end, by means of which the supports can be suspended in recesses in a vertical support, for example a wall rail or a free-standing stand. The hooks usually have a web and a downward leg, which engages behind the wall of the support below the recess when the support is suspended.

With these carriers, however, there is a risk that the carrier will be pushed upwards by an upward pushing movement so that the leg of the hook no longer engages behind the wall of the support below the recess and the carrier due to its own weight or the load forces one on the Carrier placed shelf tilts out of the recess. As a result, an assembled shelf can fall apart completely.

A carrier element according to the preamble of claims 1, 4 and 6 is already known from DE 101 08 616. This support element has two T-shaped hooks as suspension elements of the support on the shelf support, with a safety catch being additionally provided with the aid of a pivotable locking tongue. The symmetrical design of the T-shaped hooks allows greater flexibility when hanging in the shelf supports.

From EP 0 455 065 a further support for installation in shelf supports with two T-shaped hooks on the hanging bracket is known, which provides greater possibilities of variation with regard to the hanging height of the support elements. The invention has for its object to provide an improved support for a shelf, which ensures protection against unintentional detachment from a support, a simplified hanging process and / or an increased load capacity.

The object of the invention is achieved by a carrier element according to claims 1, 5 and 7. Advantageous further developments are specified in the dependent claims.

The carrier element according to the invention has a hook which is T-shaped with a web and two projecting legs, which are each directed downwards or upwards. If the carrier element is hooked into a recess in a vertical support, the lower leg engages behind the wall of the support below the recess. The upper leg prevents the carrier element from being accidentally detached, since this leg engages behind the wall of the support above the recess when the carrier element moves upward, and consequently a tilting movement of the carrier element out of the recess is prevented.

According to the invention, the hook is dimensioned such that the length of the hook exceeds the length of the recess in the vertical support. With this configuration, a reliable securing of the suspended support element is achieved, since the wall of the support reaches behind when the support element moves upwards, due to at least one of the two legs.

It is further preferred that the length of the upper leg of the hook is the length of the. ^"The lower leg surpasses. This further improves the securing of the support element against unintentional detachment, since the upper leg already engages behind the wall of the support when the support element is suspended. According to the invention, the upper leg of the hook protrudes beyond an upper edge of a horizontally projecting support rail of the carrier element. With this configuration, the suspended support element is given greater resilience under contact forces, since these forces can also be transmitted to the support via the upper leg. In this way, an increased load path results, combined with a reduced load moment acting on the carrier element.

According to the invention, a recess is provided between the upper leg of the hook and an upper edge of a horizontally projecting support rail of the carrier element. This enables a space-saving geometry of the support element, in particular if the upper leg does not protrude beyond the upper edge of the support rail. This space saving means, for example, that less material can be used in the production of the carrier element. Costs can also be saved due to smaller packaging of the carrier element.

The invention is explained in more detail below with reference to the figures. Show it:

FIG. 6 shows a detailed view of a sectional side view of the carrier element according to the second embodiment in a rotated position during the attachment process to the vertical support, and

Figure 7 shows a further side sectional view of the carrier element according to the invention according to the second embodiment, which is suspended on the vertical support.

FIG. 1 shows a side view of a carrier element 1 according to the invention in accordance with a first embodiment. The carrier element 1 has a horizontally projecting support rail 11, on which shelves of a shelf can be placed. In order to enable fixation of a placed shelf, the support rail 11 is equipped with a pin-shaped fixing element 12 on the upper edge.

The carrier element 1 is provided with two hooks 2, 15, with which the carrier element 1 can be suspended in corresponding recesses in a vertical support. The upper hook 2 is T-shaped with a web 22 and two vertically projecting legs 21, 23, which are each directed downwards or upwards. The upper leg 21 projects beyond the upper edge of the horizontally projecting support rail 11 of the carrier element 1, as a result of which the carrier element 1 is secured against unintentional detachment from a support, as can be seen in FIG.

The support member 1 is easily and inexpensively in one piece ^"of a stamped sheet metal finished. On the edge 13 with which the hinged support member 1 rests on a support, hereinafter referred to as a supporting edge 13, the carrier element 1 is additionally provided with an S-shaped embossment 34 The essentially straight line channel is thereby ten run of the support edge 13 laterally offset, as can be seen in Figure 2.

Figure 2 shows a cross section of the support element 1 according to the first embodiment with a view of the support edge 13. The S-shaped embossing 14 effectively increases the width of the support edge 13 so that the suspended support element 1 is stabilized against horizontal tilting movements.

FIG. 3 shows a sectional side view of the carrier element 1 according to the first embodiment in a rotated position when it is plugged onto a vertical support 5. Since the length of the T-shaped hook 2 is larger than the length of a recess 51 of the support 5, the upper leg 21 of the T-shaped hook 2 is inserted into the recess 51 of the support 5.

As shown in FIG. 3, the inner edge Di delimited by the upper edge of the support rail 11 and the upper leg 21 of the hook 2 is applied to the upper edge of the recess 51 of the support 5. Subsequently, the carrier element 1 is rotated into a horizontal position via the inner edge Di, which functions as an axis of rotation Di. The axis of rotation Di is oriented perpendicular to the plane of the drawing in FIG. Subsequently, the carrier element 1 is lowered and hung with the lower leg 23 of the T-shaped hook 2 and the second hook 15 in the corresponding recesses 51, 51 ^{N of} the support 5.

It can also be seen from FIG. 3 that the carrier element 1 can only be suspended in those supports whose recesses have a length that is at least as large as the distance between the inner edge D _{x and} the outer corner point of the lower leg 23 of the T-shaped hook 2 , Figure 4 shows a further sectional side view of the carrier element 1 according to the invention according to the first embodiment, which is suspended on the vertical support 5, the lower leg 23 of the T-shaped hook 2 and the leg of the second hook 15 the wall of the support 5 below the reach behind the respective recesses 51, 51 ^x .

Since the length L _{2i of} the upper leg 21 of the T-shaped hook 2 exceeds the length L _{23 of} the lower leg 23, the upper leg 21 engages behind the wall of the support 5 above the recess 51 already with the suspended support element 1. This configuration is the carrier element 1 is particularly reliably secured against unintentional detachment, for example caused by an upward impact movement.

Furthermore, this carrier element 1 is characterized by greater resilience under contact forces, since the forces are also transmitted to the support 5 via the upper leg 21 of the hook 2. The load path is consequently composed of the length of the support edge 13 and additionally of the length of the web 22 and the length L ₂ ι of the upper leg 21, which results in a reduced load moment acting on the carrier element 1.

FIG. 5 shows a side view of a carrier element 3 according to the invention in accordance with a second embodiment. This carrier element 3 is also made from a stamped sheet metal and has a horizontally projecting support rail 31 provided with a fixing element 32, an S-shaped embossment 34 in the region of a supporting edge 33 and two hooks 4, 35, the lower hook 35 being merely connected by a ^" protruding edge is formed on the support edge 33. The upper hook 4 is again T-shaped with a web 42 and two vertically projecting legs 41, 43. In contrast to the embodiment shown in the previous figures, a recess 36 is provided between the upper leg 41 of the T-shaped hook 4 and the upper edge of the support rail 31 of the carrier element 3. The recess 36 is V-shaped and has an inclined contact edge 37 in the region of the support rail 31, with which the carrier element 3 can be placed in a rotated position when hanging on a vertical support.

In order to hang the support element 3 on very narrow supports, the upper leg 41, which projects furthest into a support when the support element 3 is in position, is provided with a bevel. The upper leg 41 does not protrude beyond the upper edge of the horizontal support rail 31, as a result of which a space-saving geometry of the carrier element 3 is achieved. This shape proves to be favorable, for example, in the manufacture or in the transport of the carrier element 3.

Embodiments of the support element are also conceivable, in which an upper leg protruding beyond the upper edge of the support rail and a recess between the upper leg and the support rail are provided. Other configurations of the recess, for example in a rectangular shape, are also possible.

FIG. 6 shows a detailed view of a sectional side view of the carrier element 3 according to the second embodiment of the invention in a rotated position during the attachment process on the vertical support 5. Since the length L _{4 of} the hook 4 is larger than the length of the recess 51, the first Embodiment of the carrier element, first the upper leg 41 of the T-shaped hook 4 is inserted into the recess 51 of the support 5. The support element 3 is placed with the contact edge 37 on the wall of the support 5, which facilitates the push-on process, since the support element 3 is in a predetermined position is hung on the support 5. Subsequently, the carrier element 3 is rotated into a horizontal position on the inner edge D ₃ delimited by the edges of the recess 36, which also functions here as an axis of rotation D ₃ , and is lowered into the recess 51 by lower leg 43 of the T-shaped hook 4 the support 5 hooked.

The width B _{36 of} the V-shaped recess 36 must be selected such that the ratio of the width B ₃ 6 to the length L ₃ 6 of the recess 36 is the ratio of the width B _{4 of} the hook 4 to the length L _{35 of} the recess 36 reduced length L _{4 of} the hook 4 corresponds. This condition is illustrated by looking at the similar triangles shown hatched in the figure.

FIG. 7 shows a further lateral sectional illustration of the carrier element 3 according to the invention in accordance with the second embodiment, which is suspended on the vertical support 5. According to the first embodiment of the carrier element, the upper leg 41 of the T-shaped hook 4 engages behind the wall of the support 5 above the recess 51 already in the suspended carrier element 3, since the length of the upper leg 41 exceeds the length of the lower leg 43.

The lower hook 35 of the support element 3 also projects into a recess 51 in the support 5, as a result of which the support element 3 is additionally stabilized against horizontal tilting movements.
