Self-locking gate for cattle

The invention relates to a self-locking gate for cattle with a pivotable spar that from an open position from Animal can be moved into a closed position by pressure on the lower part of the spar, in which an actuatable catch or a Stop holds the bar in place.

Self-locking gates of the aforementioned type have become known in various types of construction. They essentially serve to

to hold the animal when it is eating, so that Barn work can be carried out. However, the gate should also be adjustable so that the animal is held tight without

i The aim of the invention is to create a self-locking gate at

which noise is excluded and which has a very simple design, so that the functional reliability is maintained in all operating situations.

: The invention is based on the self-locking gate of the introduction

ι type described and suggests that the pivotable

Spar is connected to a slider which slides on parts of the gate during the spar movement, v / obei the one of Sliding surfaces made of rubber or a rubber-like material.

The slider provided by the invention brakes the spar movement so strong that the animal only moves the spar relatively slowly. In particular, it is excluded that the spar moves automatically. The so damped spar movement now makes it possible, for example, buffers or the like Provide facilities that completely suppress noise. The advantage here is that the on the buffer or similar impacts take place with only little energy, so that the spar does not spring back occurs.

It has been found that the measures according to the invention not only greatly reduce the generation of noise will. The wear of the parts, in particular also the wear of the sliding pieces or sliding surfaces, is very low. The low cost of carrying out the invention should be emphasized.

In the preferred embodiment of the invention, the slider, which has the shape of a pipe section, is in the tubular spar out. If the slider is inserted into the lower end of the pipe, the slider can, for example rest under its own weight on a horizontally running gate part.

It is advisable to make the sliding surface of the slider in the spar from rubber or rubber-like material. this can be done, for example, that a hose or some hose pieces are pushed onto the slider.

If the hose end protrudes slightly at the lower end, there is a good sliding surface for the inventive Purposes.

The invention can of course also be modified in various ways. It is possible to use the slider to be provided at the upper end of the spar, whereby similar effects can be achieved.

The braked spar movement in the invention makes it possible that, for example, other sliding surfaces not with a corresponding rubber-like coating are provided. A fork or a bowl can be placed on the upper end of the handle be provided for guidance on a transverse gate part, whereby the spar is given improved stability. With the slow movement of the handlebar, the noise generated by this guide will remain low.

The invention also proposes a novel means for limiting the movement in front spar _s details of which result from the further subclaims and from the following description.

Representation in a different operating position.

The self-locking gate, which is shown in the drawings, consists essentially of the upper gate part 8 and the lower gate part 9, between which the vertically extending gate parts 15 to 19 extend. The gate part 19 is curved and connected to the gate part 15 and carries the bracket 20. In the bracket 20 is a hinge pin 14 is provided around which the spar 1 can be pivoted. The spar 1 can be moved from the position shown in FIG Position according to FIG. 2 are pivoted, which pivoting movement is effected by the animal, which in the open position according to FIG. 1, the head by the relatively wide opening 22 and then moved downwards, so that by pressure on the lower spar part 24 of the spar 1 in the position is brought about as shown in FIG.

The spar 1 has a fork or a fork at the upper end Shell 7, with which the spar 1 on the gate part 8 receives an additional guide.

The spar 1 is tubular and the slider 2 is pushed into the lower end of the spar 1 and is free therein movable. This slider 2 consists of a pipe section 6 of suitable length, on which a hose 5 (see. Fig. 2 and 3) is postponed. The hose 5 can also be a suitable tube or consist of several sections. the The arrangement is such that the hose 5 protrudes beyond the lower end 25 of the pipe section 6.

The head tube 10 can be rotated and d ;; eht that Gate part 3 with. The wedge-like stop 11, which surrounds the screw 28, is mounted on the gate part. When the gate part 3 assumes the position shown in FIGS. 1 and 2, the wedge-like stop 11 is inoperative. If the wedge-like But if the stop has the position according to FIG. 3, the spar 1 can no longer move out of the closed position shown Move to the open position and the animal is thus held. By means of a suitable rotary movement in the control tube 10 all gates can be opened.

A short pipe section 12, which carries a retaining ring 13, is also pushed onto the control tube 1. When the pipe section 12 has the position according to FIG. 3, the retaining ring 13 is inoperative. The pipe section 12 can, however, in the position shown in FIG. 4 can be brought and the slider 2 can be inserted into the retaining ring 13, whereby what is achieved is that the gate in question always remains closed, regardless of the position of the gate part 3 or the stop 11. If desired, by loosening the screw 28 by rotating the gate part 3 and by fixing in a functionless position, the stop 11 can be brought into a position in which it remains inoperative, so that a certain gate is always open or is always kept closed by the retaining ring 13.
