Description

Technical field of the invention

The present invention relates to an automatically closing gate, in particular for a gate in the field of pasture crossings, which is to be passed by a cyclist and/or a pedestrian. Furthermore, the present invention relates to a kit for such a gate.

State of the art

Hiking trails and/or bicycle paths in natural terrain often lead across fields or pastures on which cattle graze within an area fenced off by a pasture fence, with pasture fence gates or gates being provided which can be opened and closed again by a person passing through this pasture passage are close. Above all, electric pasture fences for herding sheep, cows, pigs and other animals with increased herding security are also known.

For electric fence passages, in particular for electric fences, gates are known after a previous opening, which automatically return to a closed position, so that in particular a vehicle can pass this without stopping. From US 16 09 369 a gate is known, which is moved by a driving against the gate vehicle from its closed position by horizontal pivoting about a pivot axis in an open position. At the same time, a support roller provided in a restoring mechanism is displaced along a stationary guide track to a higher position, from which it automatically returns to the lower position of the closed position by means of gravity.

Other mechanisms for a return mechanism, including swing doors or gates, are known. Thus, a form of a restoring mechanism with a vertical displacement associated with the pivoting movement can comprise a V-shaped connecting link and a sliding block guided thereon, or a guideway which rises on both sides and is designed as a recess, on which a roller bearing rolls. Restoring devices without vertical displacement are also known, in which the restoring force to be applied emanates, for example, from a torsionally loaded helical spring.

Conventionally, in the automatically closing gate known for pasture fences, a high contact pressure must be applied to the horizontally pivotable gate in order to open it against the action of gravity or spring force. This contact pressure has to be applied by the vehicle, which can lead to various problems. If the gate is approached too quickly and/or too hard, damage to the vehicle and/or an abrupt impact can occur, which is particularly unpleasant and sometimes dangerous for a cyclist when pushing open such a gate. On the other hand, the door can also be unintentionally pushed open by more or less strong winds, especially if the door is a large target.

The object of the present invention is therefore to provide a self-closing gate, which can be combined in particular with pasture fences, and which avoids the disadvantages mentioned above. In particular, the automatically closing gate should be set up so that cyclists can pass through it without any effort or delay, and so that it can be adapted to the topography of the installation environment. In addition, a low-maintenance gate is provided, which can also be combined with an electric pasture fence in such a way that cattle cannot pass through this gate.

Summary of the Invention

The objects of the present invention are achieved by an automatically closing gate according to claim 1 and a kit according to claim 13. Advantageous embodiments are set out in the dependent claims and in the description.

According to the invention, an automatically closing gate is proposed which can be combined with a fence, for example an electric pasture fence, with a vertical gate post which can be anchored in the ground and a pivot tube which at least partially surrounds the gate post and which can be pivoted and vertically displaced on it is mounted, with a can be arranged on the pivot tube boom, which extends largely in the horizontal direction and connectable to the boom gate element. In an intermediate space between the goal post and the swivel tube, a restoring device is arranged with two restoring elements, which are a first restoring element designed as an ascending guideway and a second restoring element guided thereon. Preferably, the guide track can be V-shaped, with rising sections extending on both sides, starting from an end point. One of the restoring elements is non-rotatably connected to the goal post and the other restoring element is connected to the swivel tube, with the opening of the gate element lifting the second restoring element from an end point corresponding to a closed position, and with the gate element pivoting back automatically when the force required for opening is lost gravity occurs, with the second restoring element moving along the first restoring element to the end point.

With this relatively simply designed reset device can be achieved that during the pivoting movement, the gate element can be opened in one direction, preferably in both directions, by simply pressing against it. For this purpose, the first restoring element can be designed as a V-shaped guide track, with the end point being at the lowest point and the second restoring element, starting from the end point, being able to be raised on both sides. Once the force to open the door is removed, the gate returns to its closed position. A robust gate can thus be provided on a path which is largely maintenance-free and opens and closes reliably. In particular, a lubricating opening can be provided on the restoring device, via which the pairing of the first restoring element and the second restoring element can be lubricated at any time.

In a preferred embodiment, the goalpost is anchored to the ground by means of an anchoring system comprising a ground screw and a base. The use of a screw foundation, which can simply be screwed into a hole prepared in the ground, has proven to be particularly advantageous with regard to the variability of the installation situation. Above all, depending on the topography of the place of use, the height above the ground can be varied, with which the entire height of the door according to the invention can also be adapted to local conditions. A base is provided between the goal post and the screw foundation, to which the goal post can be detachably fastened, for example received between vertical base brackets and fastened by means of screw connections. The base is preferably detachably connected to the screw foundation, so that a further variance of the construction is provided.

[0011] Since the automatically closing gates according to the invention are often to be set up outdoors and sometimes in terrain that can only be reached on foot or by bicycle, the weight plays a role in transporting it to the place of use. Using polyethylene as the material for the goal post, pivot tube and/or boom provides a lightweight assembly which is also weldable and recyclable. The arm can also be welded to the gate element and/or the arm to the swivel tube and/or can be connected by means of a screw connection etc.

Alternatively, the gate element can also be detachably arranged on the boom by means of screw means, which makes it easy to exchange the gate element.

The gate element itself can also be made of polyethylene. According to one embodiment, the gate element is preferably made of a material which, in particular, exhibits shock-absorbing properties. In particular, when a bicycle hits the gate element at a certain speed in order to open it, the resulting impact should be dampened so that there is no risk of injury and/or damage.

In a preferred embodiment, the gate element is in the form of a wing, in particular in a shape characterized by reduced air resistance. This is particularly advantageous in order to prevent the gate from being opened involuntarily by the wind and thus to ensure the safety of the fenced-in animals at all times. In addition, a gate element designed in this way offers the advantage that it is suitable for fast passages, in particular when used in so-called bike parks, in which case a certain speed is decisive.

Furthermore, according to one embodiment of the door according to the invention, its elements can be designed and set up in such a way that the door is not pushed open by the wind. For example, at least part of the surface of the door element can have openings to reduce air resistance. However, the weight of the gate element can also or additionally be changed by additional elements to be attached such that gravity holds the gate element in the closed position.

[0016] Electric pasture fences are used to increase the security of fenced-in animals. In a further embodiment of the automatically closing gate according to the invention, it is provided that the enclosed gate element is electrically conductive at least in defined areas. Accordingly, the gate not only represents an optical blockage for the fenced-in animals, but also a deterrent effect is achieved by the electric shock of an animal touching the gate element. Since preferably defined areas are designed to be electrically conductive, which are not touched by a person passing through the gate when they push open, this is neither dangerous nor uncomfortable for this person. Thus, in addition to an electrical strip known per se, which can be attached to the upper and/or lower edge of the door element, further electrical strips can be arranged in between and electrically contacted. Preferably, a large number of electrically contactable electrical strips extending in the direction of the ground can also be arranged on the lower edge of the gate element, which represent a kind of barrier curtain for small animals, which could otherwise slip under the gate element.

Furthermore, a handle can be arranged on the gate element, which can be grasped by a person opening the gate, in order to ensure at the same time that the person has no contact with the electrical strips when opening the gate.

In one embodiment of the invention, a cover can be attached to an upper end of the goal post, on which a printed circuit board can be integrated, whereby a protected and compact arrangement can be achieved. It is also easy to replace the printed circuit board.

In particular, it may be of interest for a region to determine the number of openings of the gates that are located on hiking or cycling trails in the area. From this information it can be generated, for example, whether a different rhythm of maintenance of the paths is required at high frequency. The information about the number of times the door has been opened can be retrieved in analog or digital form or, for example, transmitted to an evaluation unit.

[0020] Furthermore, a kit for an automatically closing gate is claimed. This kit with the elements in a lightweight and flexible design enables universal use even in very different topographical areas.

Embodiments of the invention are explained in more detail below with reference to the accompanying drawings. Features of the invention which are apparent from the drawings are to be considered, individually and in any combination, as part of the disclosure of the invention. They show: FIG. 1 a perspective schematic illustration of an automatically closing gate; 2 shows a schematic representation of a sectional view through the automatically closing gate; 3 shows an exploded drawing of the automatically closing gate; and FIG. 4 shows a schematic representation of a gate element.

Detailed character description

In Figure 1, an automatically closing gate 1 is shown according to a preferred embodiment in a perspective overall view. The goal 1 comprises a vertical goalpost 10 which can be anchored to the ground by means of an anchoring system. In particular, the goal post 10 has a lower end portion which is adapted to be received between base lugs of a base and connected thereto by means of screw connections. The base, in turn, can be detachably connected to a screw foundation inserted into a prepared hole in the ground. Depending on the topographical situation, the height of the ground post can vary. In the embodiment according to Figure 1, the goal post 10 is made in several parts, i.e. comprising a base connecting element 12 made of solid material, which is at least partially accommodated in a sleeve 14 (Figure 2).

The goal 1 further includes a pivot tube 16 which at least partially surrounds the goal post 10 and is pivotally and vertically displaceably mounted thereon. A cover 40 can be accommodated at the upper end of the swivel tube 16, which cover seals the interior of the structure. A boom 18 can be arranged on the swivel tube 16 and extends largely in the horizontal direction. A gate element 20 can in turn be arranged on the boom 18 and connected to it.

In a preferred embodiment, the elements of the goal post 10, pivot tube 16 and/or boom 18 can be made from a weldable and possibly recyclable material, so that the boom 18 is preferably welded to the pivot tube 16. The gate element 20 can either be welded to the arm 18 or can be detachably connected to it by means of screw connections. Furthermore, electrical strips can be arranged in a suitable manner on the gate element 20, as is shown by way of example in FIG. 4, in which case the shape of the gate element 20 can vary. The electric strips can be connected to the electric fence via appropriately designed connections.

In Figure 1 it is shown that on an outer circumference of the pivot tube 16, a restoring device 30 is added, which is explained in more detail below.

A sectional view of the automatically closing gate 1 is shown in FIG. 2, from which the arrangement of the individual elements of the gate 1 can be seen, in particular the arrangement of the base connecting element 12, accommodated in the sleeve 14, accommodated in the pivot tube 16. Also recognizable is the boom 18 arranged on the swivel tube 16 with the gate element 20 that can be connected to it.

According to the illustrated embodiment, the goal 1 includes the resetting device 30. The resetting device 30 is arranged in a space between the goal post 10 and the pivot tube 16 and includes a first resetting element 32 and a second resetting element 34. The first resetting element 32 can be used as a V-shaped guide track 33 may be formed, starting from a lowest end point 33.1 rising guides extend on both sides (Figure 3). Furthermore, the restoring device 30 includes the second restoring element 34, designed as a rod-shaped guide element. The second restoring element 34 is set up to be lifted along the first restoring element 32 when opening from a closed position and to automatically return to the end point 33.1 when a force required to open the gate is no longer effective. The first restoring element 32 is connected to the goal post 10 in a torque-proof manner and the second restoring element 34, i.e. the rod-shaped guide element, is connected to the pivot tube 16 in a torque-proof manner. Alternatively, however, an opposite arrangement can also be provided.

In Figure 3 is an exploded view of an automatically closing gate 1 is shown according to the invention. The base connecting element 12, accommodated in the sleeve 14, forms the goal post 10. The sleeve 14 is designed as a V-shaped guideway 33, the first restoring element 32 is formed, in particular as a correspondingly shaped recess, which starting from the end point 33.1 along the circumference of the Sleeve 14 extends helically and thus allows vertical displacement of the second restoring element 34 guided thereon. The second restoring element 34 or the rod-shaped guide element is detachably and non-rotatably connected to the swivel tube 16 and is designed to be guided safely along the V-shaped guide track 33 . To open the gate 1, a force is exerted against the gate element 20 and/or the arm 18, which is sufficient to move the second reset element 34 from the end point 33.1 along one of the sides of the V-shaped guideway 33 into a raised position. from which an automatic return of the second return element 34 takes place and thus an automatic pivoting back of the gate element 20 by gravity.

Furthermore, the cover 40 is provided, which can be accommodated at the upper end of the swivel tube 16 or the goal post 10 and which is designed in particular to accommodate a circuit board.

A further embodiment of the gate element 20 is shown in FIG. The gate element 20 has the shape of a wing, which is characterized by reduced air resistance and is therefore suitable for preventing the gate 1 from being opened involuntarily. Furthermore, electric strips 50 are arranged on the gate leaf 20, which also partially extend towards the ground in the form of individual strips and provide a kind of slip protection for small animals.
