7 and 8 a further embodiment for such a support leg,

Fig. 9 the. Attachment of the support feet to a Flat material stacks,

FIGS. 10 to 13 show a further exemplary embodiment for such a support foot.

According to FIG. 1, a box 10 made of corrugated cardboard is supported on the floor via four support feet 11, and a support leg is attached to each corner of the box. So that the fork 12 can one Reach the forklift directly under the bottom of the box and it can be lifted. If necessary, additional support feet can of course also be added to the box be attached, for example in the middle of the box or on its sides, depending on the order what load it is and where it is necessary to attach appropriate support feet.

Each support leg 11 is made of sheet metal or plastic and consists of two upright leg portions 15 and 16 which each form downwardly directed extensions of the corners of the carton 10 when attached to it. The lower ends of these foot parts 15 and 16 form the support surfaces with which they can be placed on the floor, over the truncated ends of these foot parts. On the upper parts of the support feet there are devices by means of which the feet can be attached directly to the material to be stacked or the load, in the present case to the cardboard box. Along the hypotenuse of the triangular foot part 15, a flange 17 is bent, which extends over a certain part of the length and serves as a reinforcement for the foot. The edge of this foot part can also be flanged or rolled up. From the triangular base section of the foot part 15, a flange 19 is bent inward, which is part of the fastening device and also serves to support the lowest layer 20 of the corrugated cardboard box, which is formed, for example, by the bottom flap of the carton 10. Over the foot part 15 there are also stampings 21 spaced apart, which are stamped outward and cooperate with inwardly molded stampings 21 α of the flange 19 that the flange and its angle are strengthened as a result. Pronounced or punched-out tabs 19 α engage frictionally against the lower surface of the load, and so connect the foot with this.

On the foot part 16, along its hypotenuse, there is a flange or bead 17 corresponding to the flange Reinforcement provided. Here, too, a flange 23 is bent inwards on the upper side, namely parallel and at a distance above the flange 19 and this flange also forms again part of the fastening device. The distance between these two flanges is, for example, equal to Thickness of the corrugated cardboard 20, through which the bottom of the carton 10 is formed. Also from this Foot part 16 are again shaped outwardly 24, which extend vertically along the foot and corresponding inwardly pressed impressions 24 ″ of the flange 23 pass over, which a short distance across the width of these flanges are formed to allow the corners of the foot and so that the flange supporting the load is also reinforced. There are protrusions 25 in the flange 23 formed, for example by piercing and / or by stamping material from the Sheet metal are made to the outside, namely before the flanges are bent. The protrusions 25 form rough edges 26 facing up from the flange and those with the underside of the flap 27 of the cardboard can cooperate, which covers the bottom flap 20 that the support leg in his selected position is held near the corner of the carton when the bottom flap 20 of the carton is closed and by a suitable fastening means such as a strap, by stapling, by stapling, or by means of glue. The like. Is attached.

The right-angled connection between the foot parts 15 and 16 can be stiffened by corner be reinforced, which are pressed in by the foot parts at their connection point, after the two foot parts have been brought into their right-angled position to one another. Similar Stiffeners 30 and 31 can inwardly from the base section of the foot parts and also from the flanges 19 and 23 are embossed to thereby together with the expressions 21 and 24 to contribute to the stiffening of the flanges.

According to the plan view according to FIG. 6, the support feet 11 are each attached to the corners of the carton 10 and thus form the supports for the cardboard box. They are attached to the box during the box cutting process is brought into its container shape, namely before closing the bottom of the Container, the support feet 11 each connected to the tabs of the cardboard at each corner, namely as follows, that this tab 20 between the flanges

19 and 23 comes to rest and so this section is supported on the flange 19 when the container is turned over. The flaps 20 of the carton can then move in and down into their closed position be bent and in this position by stapling or with the help of an adhesive tape in the Area 32 may be attached, or any one may be attached The usual type of fastening can be used to close the bottom of the box. When the bottom

supported are channels, with the upper flange 37 and the lower flange 44 respectively on the surfaces the bottom layer attack and the cooperating in one direction aligned sharp 5 projections 43 and 45 in the corresponding Unterzw. Intervene surface of this location and thereby the feet are held in their predetermined position in the corners of the position.

The stack of blanks 46 can then on the

closed and secured, the projections engage the lowest layer 34 and are stacked through the 26 into the underside of the inner flap 27 and attached to the strap 47, which around the stack thus effectively keep the foot in vainer position, in and under the bottom of the lowermost layer 34 is softer it is looped a downward extension and which also forms over the extension of the corners of the container is kept to it. The feet can be raised in this way or the like, the fork being permanently and firmly attached to the layer 34, and each rope can be retracted under the load. on which the flat material pieces 46 are supported In the embodiment according to FIGS. 7, 8, so that a support structure is very simple and 9 support feet 33 are created directly on the lower and cheaper construction, which a fast side of a sheet of corrugated cardboard 24 or the like. attached and 20 and easy transport with a forklift truck thereby a support is created that enables. In this case, strips, metal sheets, flat sheets or the like can serve as a support for a stack of folded-up container blanks or similarly laid cardboard blanks. In this chen pieces of flat material are transported. Embodiment, the support feet 33 from Fig. 10 to 13 show a support foot 50, which is constructed similarly at right angles to each other foot parts 35 and a ₅ Hch that of FIGS it enables a Sta-triangular parts similar to parts 15 and 16 to pel various loads and also stand. The foot part 35 has an inward direction which is suitable for supporting heavier loads. curved flange 37, which still extends beyond the edge. The support foot 50 can extend from a sheet metal blank! This extension portion 40 α 30 51 are made and bent. On one of the flange 37, the end of the foot part 35 projects beyond half 53 of this blank 51 is a section 55 and ends in a lip which is bent downwards
40, through which a bandage is held on the flange
and which allows a batch of
folded flat corrugated cardboard blanks at 35
to secure the support with suitable bandages.

In Fig. 9 shows how this protruding portion 40 α of the flange 37 a Umschnü-

rungsband 47 is held. This makes it possible to come and extend parallel to it. The lent to combine the support leg with any kind of stack of spacing between these flanges 57 and 61 depends on pieces of flat material, for example on the thickness of the flat material of the load, with metal plates, sheets of plywood or the like, for example the bottom of a container, of a board then over these sections 40 α the feet or a sheet of cardboard or another flat sheet can be attached directly to the load, 45 material part that is to be attached between these flanges via the belt 47.

From the flange 37 are right-angled protrusions from the section 55 are crescent-shaped

Tongues 41 cut out, the sharp in a Rieh-projections 63 pronounced or punched out and austen pointing projections 43 form, which are bent with the, from opposite sides of the Cooperate bottom of the corrugated cardboard box34. 5 ° blank according to Fig. 10 before turning this The foot part 36 has an inwardly bent portion of the flange 57. This semicircular flange 44, which runs parallel to the flange 37, gene projections 63 are bent upwards and at a distance above this, although the same in the direction of the flange 61, so that they are on the thickness of the corrugated cardboard 34 is selected. The flange bottom of the corrugated cardboard or the like Flachmate-44 has a downwardly pronounced rectangular shape with its sharp edges and can be punched, which in turn is sharp in a direction that is supported on this flange section 57, pointing projections 45 form, which together with when the foot along this flange with his the projections 43 a slot acting in one direction is plugged onto the cardboard, which is between the holder form, through which the feet in their see the surface of the flange 57 and the Position held on the flat material section 60 underside of the flange 61 is formed. will. The feet 33 can have crescent-shaped projections 65 which are not shown

have embossments which, if necessary, are embossed from the section 59 of the blank like the cutouts 21 and 24 are used for reinforcement. embossed or punched out on the top The feet 33 are at the corners of the lowermost of the blank. These semicircular sharp ones Location of a stack or the like. At the desired location 63 projections 65 are upwards to rest against the attached, causing the stack of sheet material to be directed and down towards the load pieces, for example flat folded flange 57 and they point in the direction of the base cardboard blanks 46, stacked and above the bottom part 66 of the flange 61 so that they are with the top

integrally formed, which is bent along the line 56 inward and then as the lower horizontal Flange 57 acts.

The second half 58 of the blank 51 is shaped similar to the half 53 and it also has one upper section 59, which is bent inward along line 60 and then the horizontal one Flange 61 forms to lie above flange 57

Engage that the bottom of a cardboard box or of another article to be supported on flange 57 and which is along the flange 57 is pushed under the flange 61. While in the embodiment shown the Projections from the flange 61 protrude upwards and downwards, it is sufficient in some cases if these Only point protrusions in one direction.

Before the blank is bent into the final shape of the support foot, elongated impressions are made 67 formed in the halves 53 and 58 of the blank parallel at a distance from one another, the approximately extend over the same height as the actual foot parts of the blank through which this Sections of the finished bent foot are stiffened.

At right angles to the vertical foot parts are support surfaces 69 and 70 inward of the blank turned. This bending over can take place simultaneously with the bending over of the sections 55 and 59 to form the horizontal flanges 57 and 61 are carried out.

While bending the flanges and support sections c the halves 53 and 58 of the blank can also be at right angles to one another at the same time bent around line 71. The blank then has the shape of a right-angled foot a horizontal flange 57 protruding inwardly from section 72 and a second horizontal flange Flange 61, which protrudes at right angles from the portion 66 inward and which is parallel in a predetermined Distance from the flange 57 Hegt, of these sections 62 and 66 also the Foot support surfaces 69 and 70 protrude inward, with which the foot is supported on the ground. The support surfaces 69 and 70 are especially suitable for such support feet and loads provided therewith to be stacked on top of one another can be.

After the sheet metal blank has been bent into the final support foot shape according to FIG. 11, the support feet are still correspondingly stiffened at the corners, as indicated by the areas 75 on the blank is. These later reinforcement impressions shown in FIG. 10 are of course only formed after bending. Two of these versions 75 are formed at the corner between section 66 and flange 57. Two further reinforcements 75 are provided at the corner between the foot 69 and the section 66. Two Stiffeners 75 extend along the bending line between the section 62 and the flange 61 and

ίο two stiffeners 75 are on the corner between the support part 70 and the foot part 72 are provided. Two other stiffeners 75 run along the Corner between section 66 and 72. These stiffening bends stiffen the corners of the foot thus the flanges, foot sections and support surfaces of the foot. These reinforcements can by pressing the corner sections of the finished foot inwards with a punch or the like after the foot in the Fig. 11 shape shown is curved.

The support foot 50 completed in this way can then * an attached to any corner of a cardboard box or other load. When the feet on a cardboard box attached, they can be attached either before or after the box is formed. The support feet described are particularly suitable for attaching to the bottom of a box after it has been assembled, namely simply by placing the feet along the corners of the box by sliding it in the slots between the flanges along opposite sides of the box bottom are formed with the protruding sharp crescent-shaped projections 63 and 65 through which creates a close connection with the cardboard bottom. The feet 50 can also be used for support of corrugated cardboard sheets or other types of cardboard boxes or sheets of material that are stacked will.

♦ o The in the above sense from a single sheet metal blank Support feet can of course also be produced by casting or extrusion made of plastic material.
