DE2300883C3 - Device for connecting two frame parts of a pallet attachment frame - Google Patents

Description

captive screw with the one upper construction site] to connect, with the thread at the free end the connecting screw with a rotary knob at the opposite end is two coaxial © Receiving openings at the apex of the other upper component penetrates, where one by a punching process Manufactured nut is arranged, which forms an integral part of the other upper component and adjacent to and concentric with the opening on the concave side of the other upper component her is arranged.

Set up with the connecting device according to the invention can easily be put together by a single worker if these frame parts are relatively heavy, because the frame parts are initially attached separately to the pallet and only then held together by means of the connecting screw. A rotation of the frame parts against each other is therefore not necessary, the gesture parts take rather their final position after assembly on the associated pallet only when the Connecting screw is fully screwed in. Such a pallet rack! withstands all demands stood and there is no risk that the connection of the two frame parts when Handling the pallet or when a forklift hits the pallet can solve.

Embodiments of the invention are explained in more detail below with reference to schematic drawings explained. It shows

In FIG. 1 one does not recognize an embodiment of a connecting device designated as a whole by 10 in their assignment to a pallet support frame 11 attached to a pallet 12 of known type. The depositing frame U is

low case made from Rohrmaierial and has two dissimilar frame parts 14 and 15, which by the connecting device 10 can be detached from one another are connected. To each frame part belong two vertically arranged SäulenteUe 16, which on their each have a lower end cooperating with a pallet foot 18 and at their upper ends lie against each other by a V-shaped component that is at a certain height above the Pallet 12 is arranged when the attachment frame on

attached to the pallet. Thus, two column parts 16, two with the pallet, belong to the frame part 14 cooperating feet 18 and an upper member 19, which with the upper ends of the column parts 16 is rigidly connected by welding or in any other way. The frame part 15 includes two column parts 16, two feet 18 working together with the pallet and an upper turkey! 20, which is based on similar Way is firmly connected to the upper ends of the associated Siiulenteile. The attachment frame 11 is in the present case provided with column parts arranged at the corner, but the frame could be used of course also train in other ways, e.g. B. in such a way that it is mediated by the pallet Column tiles arranged in the middle or at other points work together.

The frame 11 is designed so that it connects positively, but releasably, to the pallet 12 leaves. For this purpose, according to FIG. 1, each of the feet 18 cooperating with the pallet has a downwardly protruding fold 21, which is connected to the adjacent end face of the associated pallet board as well as the outer carrier of the pallet. Furthermore, each foot 18 has a something narrower, also downwardly protruding fold 22, which with the adjacent longitudinal edge of one Pallet board cooperates. The bevel 22 has an inwardly angled approach that associated pallet board near the adjacent inner surface of the associated outer carrier under-

Ar, attacks. A releasable locking part 24 present on the foot 18 cooperates with the inner longitudinal edge of said pallet board. With this arrangement, the foot 18 is held so that it cannot move in a horizontal or vertical direction with respect to the pallet and become detached from it.

The connecting device 10 enables the frame parts 14 and 15 after they have been attached to the Pallet 12 rigid, but to be detachably connected to one another. For this purpose, according to FIG. 2 and 3 as well as 6 to 8 a connecting screw 25 is mounted in aligned openings 26 and 27, which arranged in eint.n of the upper components and in the present case in the upper component 20 of the frame part 15 are. The connecting screw 25 runs in the main plane of the upper component 20; here the connecting screw protrudes from the apex of the upper part 20, and it is mounted so that it can execute limited axial movements in the bearing openings 26 and 27. On theirs The free end is the connecting screw 25 with a relatively coarse thread 28, in the present case Case fitted with a trapezoidal thread.
