Limiting barrier for large livestock parlors

The invention "relates to a limit barrier for large livestock, which is attached to a stationary vertical post in the area of the bar "and which is such Changing the width of the stand space allows a The result is a delimitation running diagonally to the bar axis.

75371ZJJ 03/25/76

With such a device should be achieved that the standing place of the animal is secured so that the milking and the animal care is possible without impairment. For this purpose, a known limiting barrier can be spread horizontally formed, wherein two articulated tubes or brackets are provided as a spreading device, which a enable scissor-like opening and closing. If the barrier is spread between the animals, there is sufficient demarcated workplace for treating the animals.

Since, however, in the known spreader when opening and If two long brackets have to be adjusted, this results in a cumbersome handling and a complex design, associated with a disadvantageous expenditure of time.

The object of the invention is to simplify the intermediate barrier structurally and in terms of operation, without its Punctures are adversely affected. For this purpose, the limit barrier according to the invention consists of one flat body rotatable about a horizontal axis, the lateral outlines of which converge in the direction of the ingot and which can be fixed in a horizontal and a vertical position

\ is,

This means that a single movable body, which can be adjusted quickly, is sufficient for the desired change in the width of the standing space can be grounded, so that the preparation of the livestock is considerably simplified. In addition, the previous structural Effort can be reduced.

In this sense, according to the invention, the body is provided with a central tube provided, which is attached to a post on the stand horizontal support is rotatably and axially slidably mounted.

If the body is a roughly triangular bracket, you can move around the work space behind the barrier in the direction of the parallel bars to expand, according to the invention, the base of the bracket can be provided with an indentation so that there is approximately a heart shape.

An advantageous possibility of adapting the barrier body to the work space required in each case for the zookeeper in The transverse direction is obtained according to the invention in that the body has two side rods which are located on the side of the central tube are pivoted out.

Further refinements are the subject of further claims.

Exemplary embodiments of the invention are shown in the drawing. Show it

a first limiting barrier taken from above, the barrier according to FIG. 1 adjusted by 90 °, a width-adjustable version seen from above, the view of an adjusting and fixing device in an enlarged representation,
the section VV from Fig. 4,

a third version seen from above on a larger scale and
FIG. 7 shows a simplified section VII-VII from FIG. 6.

The boundary barrier according to Figures 1 and 2 consists of a triangular symmetrisch.en bracket body 1, which is formed from a one-piece tube. The side bars 2 are attached to a central tube 3, which is on a support tube 4 is rotatably and axially displaceable. The support pipe is attached to a stand by means of a pipe clamp 5 post 6 in the area of the bar 7 removable and adjustable in height.

in. -'

To fix the bracket body 1, plug-in bores 8 are used, through which a fixing pin 8a is inserted into a corresponding bore in the support tube 4- is insertable. The position shown in FIG. 2 can thereby be achieved by a radial bore offset by 90 ° 8b of the support tube fixed v / ground.

Since the side bars 2 converge in the direction of the ingot 7 and run at the level of the animal's body, in the situation according to FIG. 1 they cause a reduction in the width of the standing space in such a way that the animal is pushed away somewhat to the side. As a result, the animal's freedom of movement is restricted and additional space is gained for safe treatment of the animal. The indentation 9 expands the space behind the barrier in the direction of the bar, whereby z. B. when milking the extending over the billet milk lines and their connections are more accessible m.

In order to produce the normal standing width, the bracket body is rotated by 90 ° into the position according to FIG. 2 and through the fixing pin 8a. secured.

In the embodiment according to FIG. 3, two side bars 2 a of a body 1 a are hinged to the central tube 3 so that they can be swiveled out laterally. To adapt the barrier to the animal's dimensions in the transverse direction these rods can be swiveled out and in, for example guided by articulated levers 11 hinged to the central tube 3 and through Plug holes 12 and plug pins or screws 12a in the set Can be fixed in position.

The one shown in FIGS. 5 and 6 is used to simplify operation Contraption. A locking ring 13 is arranged on the support tube 4 and fixed by a socket pin 13a. This ring is provided with locking depressions 14-, 14-a, which are on the front are arranged at an arc distance of 90. In the depressions 14, 14-a, locking cams 15 * 15a can be pushed in, and similarly on Central tube 3 are also arranged at the end at an arc distance of 90 °.

In addition, the central tube 3 is provided with lugs 16 whose angled ends 17 übersrgriffen the face of the locking ring 13, and which stop surfaces 18, 18a have which cooperate with the shank of the socket pin 13a.

In Figures 4 and 5 it is assumed that the body 1a is placed in the horizontal position and a rotation of 90 in the vertical plane is to be made. Around To execute rotation, the central tube 3 was in the direction of arrow A up to the frontal stop of the angled ends 17 on Locking ring 13 moves. The central tube 3 can now be turned clockwise (Arrow direction D) were rotated by 90 ° until the stop of the surface 18a on the shaft of the socket pin 13a, so that now the Cams 15 and 15a are in front of the locking depressions 14-a and 14, respectively and can be pushed in in direction E. The new position of the body 1a is thus fixed.

When the body 1a is returned to the horizontal position, the procedure is reversed, with the central tube After unlocking, turn it in the direction of the arrow C and in the direction of E. is inserted.

With an axial readjustment of the central tube 3 and thus of the body 1a, the device shown can also be displaced and are each fixed by the socket pin 13a in one of the bores 8c in the support tube. To secure the locking position can, as indicated by dash-dotted lines, a compression spring 19 can be provided behind the angled ends 17, which is supported on the locking ring 13, and the preload acts in the latching direction.

The example shown in Figures 6 and 7 of a width adjustable The body is characterized by its particular simplicity of construction and operation. Two trapezoidal Sheet metal plates 20 are interposed with a square

753712Z 3/25/76

pipe 21 welded «Two bracket halves 22 in the form of pipe bends are with the help of two bearing bolts 23, which the sheet metal plates enforce vertically, rotatable and as a result of elongated holes 24 also mounted longitudinally displaceably in the bracket halves 22 with a corresponding stroke. Two more protruding on both sides Bolts 25 penetrate the bracket halves 22 in the area of the front edge of the sheet metal plates 20. Within the bracket halves 22 is in each case between the .Lager bolt 23 and the bolt 25 a Tension spring 26 extended. The protruding ends of the bolts 25 fit into corresponding cuts 27 on the front edges of the dei Sheet metal plates and, as a result of the tension springs 26, cause the bracket halves 22 to latch in the selected position.

As in the previous examples, there is also one on one Pipe clamp 28 welded horizontal cross-sectionally round support pipe 29 is provided, but this is relatively is short. This support tube 29 fits into the square tube 21 and can be easily rotated in this. Near the pipe clamp 28, the support tube 29 is traversed transversely by a bolt 30 and over the opposite end of the square tube 21 is a flat iron 31 welded. Inside the support tube 29 is another tension spring 32 between the bolt 30 and one the flat iron 31 piercing clamping screw 33 unclamped. The pipe clamp 28 is not wider than the clear width of the square pipe 21. It therefore engages under the tensile force of the spring 32 partially into the square tube 21 and thereby causes a rotation lock.

To bring the bracket body from the horizontal position shown into the vertical position, you grasp it with both hands on the two bracket halves 22, pulls it forward a little, rotates it by 90 ° around the support tube 29 and lets it snap back again. The same is true for the opposite movement. The direction of rotation is indifferent. Should the ironing
