Description

Kr?· Ji "5Lf ^ t Securityna ^j

The invention relates to cantilever racks for heavy loads, in particular for lifting long goods made of wood, plastic or metal, for example sawn timber, chipboard boards, pipes, profile iron and the like, consisting essentially of uprights and cantilever arms extending from these, with holes in the uprights and hooks bent upwards on the cantilever arms, extending beyond the top of the cantilever arms, for detachable hanging in the holes, with the holes in the flanges of the uprights being arranged at the same height and at regular intervals one above the other and with the uprights preferably being designed as double-T profile uprights.

From the European patent specification EP-0061514, a heavy-duty cantilever racking system is known, which enables the cantilever arms to be suspended in a self-locking manner in perforated racking stands made of double-T profiles, while at the same time allowing the cantilever arms to be moved when suspended, whereby the cantilever arms can only be moved under a

relatively large upward inclination angle, namely at an angle of up to 80 degrees to the horizontal. To replace or add a cantilever arm, under certain conditions, i.e. if the arm is long and/or the distance is small, the cantilever arms above it and the loads on them must first be removed, which requires a corresponding amount of work and time.

The invention therefore has the task of designing the cantilever arms on their hooking side into the shelf uprights in such a way that they are particularly easy to assemble and replace, whereby the hooks of the cantilever arms should be able to be hooked into the holes at a very slight angle of inclination to the horizontal while at the same time being self-securing when under load.

The solution to the problem is achieved according to the invention in that two hooks are attached to the upper end of the suspension side of a cantilever arm, which can be hooked into an upper pair of holes, and there are also two pins at the lower end, which are designed to be inserted into matching lower holes in the uprights. Depending on the material thickness of the cantilever arms or the dimensioning of the vertical hole spacing, the hooks and pins can engage in two pairs of holes directly below one another; however, there can also be free pairs of holes in between. The hooks and pins of the cantilever arms are preferably at an angle of inclination.

In a further advantageous embodiment of the invention, it is provided that a safety lug is attached to the pins at the end of the range of movement of the pins, whereby a high level of operational reliability can be ensured.

It is particularly useful for the ^D H ;,�Lgr; e �eegr; and pins to be attached to a base plate, which simplifies production and improves parallel alignment of the individual cantilever arms to one another.

Further details, features and advantages of the invention will become apparent from the following explanation of an embodiment shown schematically in the drawings.

The cantilever rack according to the invention according to Figure 1 has several profile stands (1), at least two stands for each shelf. The profile stands (1) can be arranged at equal or unequal distances from one another. In the illustrated embodiment, the profile stands (1) are designed as double profile stands, in the flanges of which

(2) pairs of openings or punched holes (3) are arranged.

The holes (3) can be provided in one flange (') or in both flanges of the double-T beams and can have any shape, for example square, round or oval. The holes (3) of each pair are at the same height and are arranged one above the other at a certain distance from each other, with the reference number (3) designating the pair of holes used by a cantilever arm (5) for suspension and located under the pair of holes (3). Depending on the structural design, free holes not required for cantilever arm fastenings can be provided between the pairs of holes (3, 3').

(3) II.

The cantilever arms (5) to be suspended in the holes (3) have claws or hooks (10) at one end in extension of the top (6), with which they can be suspended in a detachable manner in a pair of holes (3). It is clear that any number of cantilever arms (5) can be suspended in a stand (1) in a simple manner, namely at predetermined and desired heights and that, if necessary, a

The height of the cantilever arms (5) can be changed.

As is clear from Figure 2, the hooks (10) are designed according to the invention to be inserted into the holes (3) at a certain angle of inclination (alpha) relative to the horizontal, whereby the pins (20) then engage in the row of holes (3) below. The pins (20) have a securing nose (21) at their end, the length (I) of which is smaller than the free hole width (a) remaining in the upper opening (3) when suspended. The difference between (a) and (I) can be approximately 3 mm. The cross-sections of the punched-out holes (3), the hooks (10), and the pins (20) are expediently adapted to one another in terms of shape.

A base plate (7) is attached to the end of a cantilever arm (5), which can be welded to the cantilever arm (5), for example. Particularly good support of the cantilever arms (5) on the Profi I stand (1) is achieved by dimensioning the height of the base plate (7) such that the end (7') always protrudes beyond the lower edge of the lower holes (3') and thus forms a contact surface with the flange (2) when suspended.

7 r Mounting a cantilever arm (5) on a stand (1) the two hooks (*0) are placed through the cutouts (3) in the flanges (2) at an angle (alpha) of about 10 - 20 degrees to the horizontal and threaded through (starting position for hanging

shown in dashed lines in Fig. 2). The cantilever arm ⁽ 5) is then brought into the horizontal position, with the two lower pins (20) now engaging with the lower row of holes (3). When suspended, the undersides of the pins (20) rest on the lower edges of the openings (3'). The safety lugs (<? I ) prevent the connection between the cantilever arm (5) and the stand (1) from being accidentally released, for example if a cantilever arm is touched or knocked by a forklift truck. At the same time, the safety lugs (21) allow a certain mobility of the cantilever arm in the range of motion (b). The connection is released, for example to change a cantilever arm, in the same way in reverse order.

The invention provides an improved possibility of changing and simplified assembly of the cantilever arms without additional fastening and

The measures according to the invention are not limited to the embodiment shown in the drawings. For example, without departing from the scope of the invention, the pins ·■-■··■' safety lugs can have any shape. The respective structural configuration is left to the expert in adaptation to the specific use.
