description

The invention is concerned with a spacer element for panels to be spaced apart, especially for heavy-duty ones Pallet, which has a tube which at least one of its ends several in an essentially axial direction Fastening tabs extending in the direction for penetration in a cover plate and for connecting the tube with the Cover plate of the pallet, as well as several support parts extending at an angle to the fastening straps, as well as having a polygonal cross-sectional shape, wherein in the transition area axially extending kink zones are provided between the fastening lugs and support parts and fastening lugs, Support parts and tube are formed from a one-piece workpiece.

The example from US-PS 3 64-1,948 (Figures 1 and 12) known distance element must be so firm that it, among other things Can withstand hitting or pushing forks, which between the spaced plates for raising and lowering the pallet to be introduced. However, the known spacer element can only meet this requirement if a relatively strong one is used Sheet metal because the khick zones, i.e. those on opposite sides Sides of a single flat tube wall, only as an exception contribute to the polygonal tube shape of the spacer element, namely at corner sections that, for example, at every third or every second fastening tab are formed. This means that the flat sheet metal section, which extends between two khick zones and actually contributes to the polygonal tube shape, is relatively large and therefore | is relatively easily deformable under the influence of blows or bumps from a fork.

To eliminate this disadvantage, the invention is intended to create a stiffer and more economical spacer element will. According to the invention, this results from the fact that each defined between two adjacent kink zones and a support part associated with the tube wall section relative to two other adjacent, opposite one another Tubuswandsbschnitte extends at an angle.

Referring to the accompanying drawings, an embodiment of the invention will be described in detail below shown. Show it:

Fig. 1 is a perspective view of a partially cut-out spacer element that the Embodied features of the invention;

2 shows a plan view of a sheet metal section from which the spacer element according to FIG. 1 is made can be and from which a number of teeth are punched;

Fig. 3 is a similar plan view as, Fig. 2, in the

however, every other tooth is bent to form support members;

4 shows an end view of the spacer element according to the invention, that is bent to its final shape;

Fig. 5 is an end view of part of an inventive, slightly modified spacer element;

6 shows a side view of a load pallet with spacer elements according to the invention.

The production of the spacer element according to the invention comprises three work steps, namely punching, bending and welding. According to FIG. 2, two groups of similar teeth 2, 2 'of triangular or pointed shape are punched out of a sheet metal section 1. Each of these two groups 2, 2 ¹ has ten teeth, 3, 3a, 3, 3a .... etc. At one end of the sheet metal section 1, a part 4 is provided, at the opposite ends of which no teeth or tooth-forming sections are in front.

are seen. This part 4- points at the top and at the bottom End of straight edges 5, d.eren mutual distance is essentially equal to the distance between opposite valleys 6 between respectively adjacent teeth 3, 3a. In In practice, the metal sheet section 1 can be made of galvanized sheet metal with a thickness of approximately 1 mm.

According to Fig. 3, every second tooth of the two groups of teeth 2, 2 ' at an angle, namely at right angles to the path of the sheet metal cut 1 turned. The teeth 3 are bent relative to the track section and form support parts, while those therebetween lying teeth 3a remain unaffected and fastening tabs that can penetrate wood or a similar material.

1 and 4- show that the sheet metal section according to Fig. Has received a polygonal tube cross-sectional shape through axially extending kink zones of two types, namely on the one hand by first kink zones 7, which are in the transition area between the fastening tabs 3a and the support parts 3 and on the other hand by second kink zones 8, which extend from the tips of the fastening straps essentially parallel to the first kink zones 7. During this bending or kinking, the teeth 3 forming the support parts are ^{directed towards the center of the tube 1} and the sections of the sheet metal that are associated with the fastening tab teeth 3a are directed inwards in a similar manner to the center of the tube, so that the second kink zones are arranged closer to the center of the tube ¹ than the first kink zones 7. After the bending of the sheet metal section according to FIG. the opposite end section 'is welded on at one or more suitable welding points 9.

In the embodiment shown, ten teeth 3, 3s are provided in each group, which means that the Number of the essentially flat tube wall sections 12, which are defined by two first kink zones 7 is five, from which it also follows that the sheet metal section or the Tube has received a pentagonal shape. This cross-sectional shape as well as other higher order cross-sectional shapes, i. with even more teeth and kink zones is of particular advantage because of the number of reinforcing, bent tube wall sections is large, regardless of where a fork hits the spacer. Each barrel wall section 12 is relative inclined to two adjacent tube wall sections 12 on the opposite side. The kink zones 7 and 8; are relative spicy. This means that the support parts 3 or fastening tabs 3a have a substantially triangular shape when viewed from above to have.

In the alternative embodiment shown in FIG According to the invention, several, in the example shown three, second kick zones 8a, 8b and 8c are provided and each pair assigned by fastening tabs 3a. The first two mentioned these kink zones or edges point inwards towards the center of the spacer element, while the last-mentioned kink zone extends from the tip of the tab and faces outward.

Finally, Mg. 6 shows a number of spacer elements, each designated as a whole by 10 (of which preferably four are arranged at the corners), which connect the two wings forming plates 11 and keep them at a distance, so that the fork of a forklift or the like. can be inserted between the plates.

The spacer element according to the invention "brings numerous advantages. Due to the polygonal cross-sectional shape of the tube the spacer element, as mentioned, can be made from a relatively thin and inexpensive sheet metal, although the required against a load on the pallet as well as against hitting or knocking with a fork Maintaining or even improving resilience will. Since the teeth 3a associated tube wall sections not only along the path of the tube but also along the tabs or the Parts-forming areas are bent or kinked, while continuous between opposite web tips. respectively. contiguous kink zones are formed, the teeth or fastening straps have an extremely good stiffness, so that, despite the relatively small material thickness, they are securely pressed into the plates 11 without any tendency to bend can. Another important advantage is that the support parts 3 are bent inwards towards the center of the spacer element are so that their normally sharp edges are bent inwardly relative to the spacer wall and there For example, do not injure the operator's hands or clothing when maneuvering the pallets can.

The invention is obviously not limited to the one described and limited to the embodiment shown in the drawings. For example, a form of a spacer element is within the scope of the invention that only with one Tooth group is provided so that the spacer element is connected to a plate at only one of its ends, while the other end of the spacer element can be supported directly against the respective floor. Furthermore, the number of the teeth in each group, as mentioned, must be greater than the number of ten shown in the drawings.
