Abstract

Barrier with a barrier upright and a drop-gate pivoted thereto. The barrier upright consists of a stump (12) with an upper limiting surface (13) directed at an angle β to its longitudinal extent. The end of the drop-gate (11) nearest to the stump (12) forms a limiting surface (14) at an angle (90°-β) to the axis of the drop-gate. The stump (12) and the drop-gate (11) are mutually pivotable and rotatable at their adjacent limiting surfaces so that the drop-gate may be pivoted between a vertical and a horizontal position.

Description

Cabinets

The invention relates to a barrier, comprising a barrier post and a baffle connected via a joint, so that the baffle can be pivoted between a horizontal and a vertical position.

Known barriers of this type have significant disadvantages. On the one hand, the formation of the joint is relatively complicated and, in addition, essential parts of the joint are exposed to the outside, so that they are exposed to willful destruction. In order to prevent this at least partially, the barrier post is usually made relatively large in order to create a casing for the functional parts.

The invention is based on the problem, on the one hand, of designing a barrier of the type mentioned at the outset to be reliable, but on the other hand reducing the possibilities of destruction by means of design measures to a minimum. The barrier should preferably be reduced to the simplest geometric shape. This is preferably achieved in that the barrier post is designed as a stump with an upper boundary surface oriented at 45 ° to its vertical extension, the barrier boom is formed at its end adjacent to the stump or barrier post with a boundary surface oriented at 45 ° to the axis of the barrier tree and in that the stump and the turnpike are attached to their adjoining boundary surfaces so that they can be rotated and pivoted relative to one another in a controlled manner.

The present invention is not limited to a cylindrical shape of the post and a conical shape of the barrier, although this can be achieved according to the invention, a seamless configuration without a heel being possible in the extended position of the pole and barrier.

In the case of barriers designed according to the invention, the delimiting surfaces of the post and the barrier are above or on top of one another. They can be rotated with respect to one another about their axes, which do not necessarily have to pass through the center of the two boundary surfaces. However, if the point of intersection of the axes is in the middle of the boundary surfaces, then when the two elements are in the extended position, a unitary structure results, consisting of a cylinder stub that changes into a cone shape at the boundary surface. It is also possible to assign two barriers to one stump so that a kind of gate is created when the barrier is closed.

When pivoting the barrier, not only can the barrier be rotated about its own axis, but at the same time the post is rotated in a coordinated manner around its axis. It is thereby achieved that the turnpike performs a movement in which it lies essentially in a vertical plane. With controlled, counter-rotating rotation of the barrier and post, an approximately bell-shaped movement characteristic of the pivoting movement of the barrier is generated, namely a characteristic in which the barrier first performs a slow movement from its horizontal closed position, which is followed by a rapid movement that finally again in a slow movement to the vertical position, the open position of the barrier. In a corresponding manner, a movement "slow-fast-slow" should be achieved during the closing process.

According to another preferred embodiment, the aforementioned movement characteristic can be achieved by using a cardan joint or any other joint in which the output shaft or the extension of the output shaft of the drive motor has been connected to a joint part which has an output shaft part at an angle of 45 °. The turnpike is attached to the output shaft off-center to the shaft and, when it changes from the open to the closed position or vice versa, therefore performs movements on the surface of a cone. When using such a joint, in particular a 45 ° cardan joint, it can be achieved that the motor drives its output shaft at a constant speed and yet the turnpike performs the desired "slow-fast-slow" movement when opening and closing.

It is obvious to vary this characteristic by designing the articulation so that it meets the requirements. For example, a very slow movement of the barrier into and out of its horizontal position could be desired, while the transition to its vertical position can be carried out more quickly. For this purpose a gimbal transmission of the Rotary movement performed in which the angle of attack, but also the axial assignment of the parts to each other can be varied accordingly.

It is important that the functional elements for the turnpike or the post can be arranged inside or below the post. However, the rotary drive for the barrier could be accommodated in the interior of the barrier.

It is also possible to provide several such joints, for example in the area of the turnpike, in order in this way to design a barrier which, for example, covers a relatively large width in the horizontal position of the turnpike, whereas only a small one in the vertical arrangement of the turnpike Height is required.

The invention is explained below with reference to the drawing, for example:

Fig. 1 shows a front view of a barrier according to the invention.

Figure 2 is a cross-sectional view through a barrier post according to the invention.

Fig. 3 shows a front view of another embodiment of the barrier according to the invention.

At 12, a post or a turnpike bracket is shown in the drawing, which stands in some way on a foundation and consists of a tubular structure stretched upwards. This can be a cylinder, a cone, a square or the like. The post 12 ends at its upward-facing boundary in a boundary surface 13 oriented at an angle of 45 ° to its vertical extent. This surface is provided with openings (not shown) for control and drive parts and can act as a support for a part to be described, namely one Turnpike 11 serve.

The turnpike 11 can also be a cylindrical, a conical or an angular part which is formed with its end facing the post 12 with a limiting surface 14 formed at an angle of 45 ° to its longitudinal extent. The surface 14 is also equipped with through openings for drive and control parts for the movements of the barrier 11.

1, the two boundary surfaces 13 and 14 lie one above the other, but can perform movements relative to one another, the drive parts required for this are not shown in FIG. 1.

For example, it is possible to turn the barrier 11 about its own axis, the boundary surface 14 lying on the boundary surface 13 one above the other. With a corresponding rotation about its own axis of 180 °, the turn boom 11 has pivoted from the position shown by 90 ° into the vertical position shown with broken lines, that is to say the barrier has changed from the closed to the open position.

It is also possible, at the same time as the movement of the turntable about its axis or about the intersection with the axis of the post 12, to turn the post 12 in opposite directions about its own axis, for example by approximately 90 °, so that it is controlled in opposite directions Swiveling of the two Parts 11 and 12 of the barrier 11 perform a movement lying essentially in a vertical plane.

It is easily possible to accommodate the control parts required for the movement in the post 12 or in the foundation of the post 12 and to arrange the corresponding drive elements in the interior of the hollow post 12 or the barrier 11. As a result, a barrier has been created which, seen from the outside, has been formed from simple geometric shaped bodies and which is not characterized by any parts which protrude outwards. It is also possible, with the barrier according to the invention, to protect all the functional parts inside the post from the outside and to secure them against any unauthorized access. Finally, by appropriately controlling the swiveling and rotating movement, it is possible to give the barrage such a temporal movement that corresponds to the desired movement characteristic.

FIG. 2 shows a cross-sectional view through a barrier post 12 according to the invention, details being given by which it can be achieved that the barrier boom 11 from its 90 ° position (horizontal position) shown in FIG. 2 to the barrier post 12 can be brought into a position with vertical orientation to the barrier post 12.

20 with a floor part is designated, which is fixedly attached to a foundation in any way. In the middle of the bottom part 20, a mandrel 21 also projects in a stationary, vertically upward direction, on which ball bearings are fastened, which rotatably support a substantially cylindrical jacket 22 with a diameter of the order of 30 cm, so that the jacket 22 by one vertical axis can perform rotary movements. In the upper part of the casing 22, a geared electric motor 23 is fastened, the output shaft extension 24 of which projects upward and can carry out rotary movements over approximately 180 ° in a controlled manner. These rotary movements are transmitted via a joint, a universal joint and in particular a 45 ° universal joint 26 to the turnpike 11 so that it can be moved from its vertical to its horizontal position and vice versa, the jacket 22 rotating about its axis by 90 ° , while the barrier 11 rotates about its axis by 18 ° and the axis is rotated 90 ° in opposite directions.

Simultaneously with this pivoting movement of the turnpike, the jacket 22 of the barrier post carries out a rotational movement of about 90 ° about its axis. This combined movement is achieved via a cam or cam disk 30 which is rotatably mounted on the output shaft extension 24 of the motor 23. The disk 30 with the cam track 31 executes a 180 ° movement, the cam track 31 extending over 180 °, but being radially different from the center of the shaft 24 or the disk 30. The track 31 of the disc 30 is by a driver or the like. scanned and transmitted via a shaft 25 to the bearing of the jacket 22, so that it accordingly carries out the controlled 90 ° rotation about its axis.

The end result of this movement is actually that the barrier post 12 is in its one position in vertical alignment with the barrier 11. In the other position, the barrier 11 is oriented at a 90 ° angle to the barrier post 12. The boundary surfaces of turnpike 11 and barrier post 12 are not only superimposed in the end positions but also during the actuation process, as can best be seen from FIG. 1. In the closed position of the barrier shown in FIG. 2, the jacket 22 cannot carry out a rotary movement about its own axis, because it is prevented from doing so by the gear mechanism or the stopped electric motor 23. However, if the requirement is that the jacket 22 should perform a 90 ° rotation about its axis in the closed position, this can easily be achieved by design measures. This corresponding requirement arises if it is to be achieved that the drive mechanism of the barrier cannot be destroyed, for example if a rider drives into the closed barrier. If in this case the jacket 22 or the barrier post 12 can make a -90 ° rotation about the vertical axis, then at most destruction could result in the outer area of the turnpike, but not in the functional parts of the drive.

The desired requirement can easily be achieved by a coupling, it can be achieved by a pin with a predetermined breaking point. However, it is also possible to transmit the rotational movement which is transmitted between the drive motor 23 and the casing 21 by a device which has mutually offset positions in which rotational movements can be transmitted. These positions preferably have an angular position of 90 ° to one another.

The invention is not restricted to the barrier post 12 being arranged vertically to the foundation. It is possible to attach it to a vertical wall at any angle, preferably at an angle of 90 °. Fig. 3 shows an application where the barrier post 12 or the jacket 22 is passed through a passage in an outer wall 40 of the house. In operation, this barrier can show the features and characteristics already described in connection with FIGS. 1 and 2.
