Description

The invention relates to a support foot for parking for forklifts suitable for transport

Extra loads, in particular packaging boxes, stacks of boxes or the like, with a device attached to the upper part of the foot for its immediate attachment on a load, the fastening device consisting of two vertically spaced one above the other

as arranged holding parts exists, between which a flat part of the load, in particular the bottom layer of a stack of flat material or the floor flaps a cardboard box can be inserted.

It is known to use block-like support feet over brackets or the like to be attached to a grate on which a load can be placed (French patent specification 1 530 386). The support feet cannot be attached and removed very easily here and this known type of support leg would not readily lend itself to direct attachment to the The bottom of a load, for example the bottom of a cardboard box, is suitable.

It is also already known to pass through block-like plastic support feet directly on the bottom of a cardboard box to attach a fastening part that can be snapped into a hole in this support leg, which is inserted from the inside of the box through a hole in the bottom of the box (USA patent 3 316 861). This known support foot can not be attached and very easily can be removed again, especially not on fully loaded cardboard boxes, as this is used for fastening Free access to the inside of the box is a prerequisite.

The same applies to another known support foot (US Pat. No. 3 251 320), which from consists of a flat iron bent in the shape of a loop and of which two are vertically spaced from one another arranged straight flat iron pieces protrude.

which can be inserted into corresponding recesses in a rigid solid base plate. This well-known The support foot is through holes in the flat iron loop or in the protruding flat iron pieces screwed to the solid base plate, so again difficult to remove and reusable. In this form, it could also not be directly attached to a load, for example on the floor of a Cardboard boxes or the bottom layer of a flat material stack, as it is not the right one for the Support would find the necessary support.

It is the object of the invention to provide a support foot for parking of forklift trucks suitable for transport To create loads that can be easily

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 can be attached or any other conventional type of attachment for closing the bottom of the cardboard box. When the bottom is closed and fastened, the protrusions will grip 26 into the underside of the inner tab 27 and thus effectively hold the foot in its position, in which he forms a downward extension of the corners of the container. The container can then loaded and by the fork of a forklift or the like. Be lifted, the fork of can be retracted under the load on either side.

In the embodiment according to FIGS. 7, 8 and 9, support feet 33 are attached directly to the underside of a sheet of corrugated cardboard 24 or the like, and this creates a support which serves as a support for a stack of folded cardboard blanks or the like. In this exemplary embodiment, the support feet 33 consist of foot parts 35 and 36 which are at right angles to one another and which again consist of inverted right-angled triangular parts similar to parts 15 and 16. The foot part 35 has an inwardly curved flange 37 which still extends beyond the edge. This extension portion 40 a of the flange 37 protrudes beyond the end of the foot part 35 and ends in a downwardly bent lip 40 through which a bandage can be held on the flange and which makes it possible to support a stack of flat corrugated cardboard blanks on the support by means of suitable bandages attach.

In Fig. 9 shows how a binding band 47 is held via this protruding portion 40 α of the flange 37. This makes it possible to combine the support leg with any kind of stack of flat pieces of material, such as metal plates, od sheets of plywood. Dg!., As can α over these sections 40 feet are permanently attached directly to the load, via the wrapping band 47.

Right-angled cutouts 41 are cut out of the flange 37, the sharp ones in one direction Form pointing projections 43 which cooperate with the bottom of the corrugated cardboard box 34. The foot part 36 has an inwardly curved flange 44 which runs parallel to the flange 37 at a distance above this which is chosen equal to the thickness of the corrugated cardboard 34 The flange 44 has downwardly pronounced rectangular punchings, which in turn are sharp in one direction Pointing protrusions 45 form which, together with the protrusions 43, act in one direction Form holder by which the feet are held in place on the flat material section will. The feet 33 can have characteristics, not shown, which, if necessary, like the characteristics 21 and 24 are used for reinforcement.

The feet 33 are attached to the corners of the lowest layer of a stack or the like at the desired location, whereby the stack of flat material pieces, for example flat folded cardboard blanks 46, can be stacked and supported above the floor, the upper flange 37 and the lower flange 44 each attack the surfaces of the bottom layer and the cooperating in one direction aligned sharp projections 43 and 45 in the corresponding sub and. Engage surface of this layer and whereby the feet are held in their predetermined position in the corners of the layer.

ίο lowermost layer 34 can be stacked and through the Tape 47 is attached to it, which is wrapped around the stack and under the bottom of the bottom layer 34 is and that is also guided over the extension of the lower flange 37 and through the Lip 40 is held on it. The feet can be permanently and firmly attached to the layer 34, on which the flat material pieces 46 are supported, so that a support structure is very simple and cheaper construction, which is quick

ao and easy transport with a forklift truck. Strips, metal sheets, flat folded container blanks or similar pieces of flat material can be transported.
10 to 13 show a support foot 50 which is constructed similarly to that according to FIGS. 1 to 5, but which is further developed so that it enables different loads to be stacked and is also suitable for supporting heavier loads. The support foot 50 can be produced from a sheet metal blank 51 and bent. A section 55 is formed on one half 53 of this blank 51, which is bent inward along the line 56 and which then acts as a lower horizontal flange 57

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 the position above flange 57

comes and extends parallel to this. The distance between these flanges 57 and 61 depends on the thickness of the flat material of the load, for example the bottom of a container, a board or a sheet of cardboard or some other piece of sheet material attached between these flanges shall be.

Crescent-shaped projections 63 are embossed or punched out and bent out of section 55, from opposite sides of the blank according to FIG. 10 before it is turned Section to the flange 57. These semicircular projections 63 are bent upwards and although in the direction of the flange 61, so that they are at the bottom of the corrugated cardboard or the like flat material layer can engage with their sharp edges, which are supported on this flange section 57 when the foot is attached to the cardboard along this flange with its slot, which is between the surface of the flange 57 and the bottom of the flange 61 is formed

Crescent-shaped projections 65 formed in themselves are embossed from section 59 of the blank or punched out on the top of the blank. These semicircular sharp ones

Projections 65 are directed upwards to bear against the load and downwards towards the Flange 57 and they point in the direction of the foot part 66 of the flange 61, so that they are with rip.r upper

surface of the corrugated cardboard blank od. Like. 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 support foot shape, 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.

During the bending of the flanges and support sections, the halves 53 and 58 of the blank can also be bent at right angles to one another around the line 71 at the same time. The cut has then the shape of a right-angled foot with a horizontal flange 57 extending from the section 72 protrudes inward, and a second horizontal flange 61 perpendicular to the section 66 protrudes inward and which is parallel at a predetermined distance from the flange 57, wherein the foot support surfaces 69 and 70 also protrude inward from these sections 62 and 66, with where the foot is supported on the ground. The support surfaces 69 and 70 are especially suitable that such support feet and loads provided with them can be stacked on top of one another.

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 bends 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 provided at the corner between the support part 70 and the foot part 72. Two other stiffeners 75 run along the corner between section 66 and 72. These stiffener bends at the corners of the foot so stiffen the flanges, the 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 in F i g. 11 ao shown is curved.

The support foot 50 thus completed can then be attached to any corner of a carton or other load be attached. If the feet are attached to a cardboard box, they can either be in front of or as well »5 must be attached after the cardboard has been formed. The support feet described are particularly suitable for attachment to the bottom of a cardboard box, after this is completed, simply by the fact that the feet along the corners of the Cardboard boxes are attached by sliding the slots between the flanges are formed along opposite sides of the carton bottom, with the protruding sharp crescent-shaped ones Projections 63 and 65 through which a close connection with the box bottom is made. 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.

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