Cubicle Partition

Abstract: The invention relates to a cubicle partition comprising at least one standing pipe (2) and, connected thereto, a bracket-shaped rail (5) bent from tube material, wherein a mounting plate (4) is fixed to the bottom end of the standing pipe (2). The standing pipe (2) comprises a reinforcing foot (10) which extends diverging downward from a distance above the bottom end.

Description: The invention relates to cubicle partition comprising at least one upright pipe and, connected thereto, a bracket-shaped rail bent from tube material, wherein a mounting plate is fixed to the bottom end of the upright pipe, said upright pipe comprising a reinforceing foot which extends converging towards the upright pipe upwardly from the mounting plate, along the bottom end of that upright pipe. Such a cubicle partition is known from NL-A-8 300 919. Cubicle partitions of this kind are used in so-called cubicle stalls to define cubicles or areas where cattle can lie down individually, for instance to ruminate. There is a clearly discernable trend in dairy cattle farming towards larger dairy cattle. This has the consequence that the cubicles and therefore the cubicle partitions must also become larger. In addition the cubicle partitions must also become stronger because of the heavier loads that can be expected from the larger cattle. In order to make the known cubicle partitions sufficiently rigid and strong, the mentioned reinforcing foot is arranged. This provides for a better resistance against bending the upright pipe and contributes to the overal rigidity and strength of the cubicle partition. The invention has for its object to provide a cubicle partition of the type specified in the preamble which has a further improved strength and rigidity with an efficient use of material. With the cubicle partition according to the invention this object is achieved with the characterizing measures of claim 1. By not fixedly welding the conical body at the top to the upright pipe but causing the connection to be brought about by means of the zinc applied during hot zinc-dipping, a construction is obtained wherein the bending loads on the upright pipe are absorbed equally by both the reinforcing foot and the upright pipe portion enclosed by the reinforcing foot. A further strengthening of the cubicle partition according to the invention is achieved with the step of claim 2. An additional advantage of the cross connection is that this prevents the cattle accidentally stepping between the two upright pipes and through the cubicle partition. This could lead to injuries. The invention also relates to and provides a cubicle stall comprising a number of cubicle partitions according to the invention disposed adjacently at mutual intervals. A cross pipe such as a shoulder bar is therein fitted at least along the tops of the adjacent cubicle partitions and connected to each thereof by couplings. According to a further development of the invention the step of claim 3 is therein applied. By embodying the couplings in this manner a completely stiff connection of the cross pipe to the cubicle partitions is obtained, which contributes to the stiffness and strength of the assembly. A further favourable development is therein characterized in claim 4. The invention is further elucidated in the following description with reference to the embodiments shown in the figures. Fig. 1 is a perspective view of a part of a cubicle stall with cubicle partitions according to the invention. Fig. 2 is a partly broken away detail view along arrow II in fig. 1. Fig. 3 is a perspective detail view along arrow III in fig. 1. Fig. 4-6 show views corresponding with fig. 3 of alternative embodiments. Shown in fig. 1 are two cubicle partitions 1 which are arranged at an interval adjacent to one another and which define between them a cubicle for a dairy cow. Each cubicle partition 1 comprises two upright pipes 2, 3 to the bottom end whereof is fixed a mounting plate 4. The cubicle partition 1 is screwed fixedly to the ground using the mounting plate 4. Extending at the top end of the upright pipes 2, 3 is a rail 5 forming one entity therewith. Together with the upright pipes 2, 3 the rail 5 is bent in further per se known manner from tube material. As fig. 2 shows in more detail, upright pipe 2 comprises a reinforcing foot 10 which extends converging towards the upright pipe, upwardly from the mounting plate 4. In the embodiment shown the reinforcing foot 10 is a frustro-conical body welded fixedly with its bottom end 13 onto the mounting plate 4. At the location of its upper edge 12 the reinforcing foot 10 is not welded to upright pipe 2. A join is formed between the upper edge 12 of reinforcing foot 10 and the upright pipe 2 during hot zinc-dipping of the manufactured cubicle partition 1, since the zinc in fact thereby forms a solder connection. In order to ensure that during zinc-plating the liquid zinc can flow properly into the interior of the reinforcing foot and the interior of the upright pipe 2 a number of holes 14 are bored in the mounting plate 4. Likewise arranged in the reinforcing foot 10 close to the upper edge 12 are a number of holes for zinc. Owing to the thus embodied strengthening it becomes possible to load upright pipe 2 considerably more, so that given the same material for the upright pipe 2 the cubicle partition 1 can take a larger form and/or is more robust. According to a further development a cross pipe 6 is welded fixedly between the top ends of upright pipes 2, 3. This forms a reinforcement for the cubicle partition 1 and at the same time a passage guard which prevents the cattle accidentally walking through the cubicle partition 1, with the risk of damage this entails. As is shown in fig. 1, the cubicle partitions 1 are curved with small bend radius. The bend radius of the inner bends lies generally in the order of magnitude of the thickness of the tube material. Thus achieved is that both the head room 7 and the body room 8 are of maximum size and therefore give maximum freedom to the cattle. As fig. 1 shows, a shoulder bar 22 is fitted along the tops of the adjacent cubicle partitions connected by couplings 23 to each of the rails 5 of the cubicle partitions 1 and 15. The coupling 23 used is shown in more detail in fig. 3. As can be seen therein, coupling 23 comprises two coupling parts 24 each having a U-shaped section with flanges bent transversely outward. In top view the coupling parts 24 are substantially square. Arranged in the flanges are four screw connection holes. These holes are positioned in accordance with the corner points of a square. It is hereby possible for the two coupling parts 24 to be connected by bolts 25 as shown with the flanges lying against one another turned through 90°. The coupling 23 forms a very stiff connection between the shoulder bar 22 and the rail 5 and thus contributes to the strength of the assembly of cubicle partitions and shoulder bar. As can be seen in the figures, a head bar is furthermore arranged at the front with similar couplings, which has an additional strengthening effect. With a coupling of the type such as coupling 23 of fig. 3 tubes of different diameter can also be mutually connected. Such an embodiment is shown in fig. 4. The same shoulder bar 22 is here joined to a thicker tube 27. The coupling part 24 extending round the shoulder bar 22 remains unchanged. For the thicker tube 27 a coupling part 26 is used which has a correspondingly larger "U". The holes in the fixing flanges are however arranged at the same mutual position so that the coupling part 24 can be connected thereto in similar manner. It will be apparent that by providing a limited number of different coupling parts such as 24 and 26 tubes of differing diameters can be rigidly connected to each other in random combinations. For a still more rigid connection, according to a further development a square plate can be received between two coupling parts. As shown in fig. 5 this square plate 30 is provided with screw connection holes 31 lying in the same relative positions as the holes in the coupling parts 24. Tube engaging protrusions 32, 33 are formed in plate 30. As shown, these comprise a pair of parallel, upward protruding ribs 32 and a pair of parallel, downward protruding ribs 33. These tube engaging protrusions 32, 33 ensure a better clamping of the tubes relative to each other, whereby they can withstand greater mutual swivel and rotational forces. Fig. 6 shows an alternative wherein the intermediate plate 35 is made of hardened steel and provided with tube engaging protrusions in the form of sharp points 36 and 37 protruding to both sides. When the bolts 25 are tightened these points 36, 37 grip into the tubes for connecting, whereby they are very well fixed. The invention is not limited to the embodiments shown in the figures. A so-called freely suspended cubicle partition with one upright pipe at a front end can also be embodied in favourable manner with a reinforcing foot according to the invention, whereby it can withstand heavier loads.
