Description

Automatic sliding and swing gate

The present invention relates to a single port and to a double port for closing off a passage which single and double port are intended to be opened and closed automatically.

Existing ports are described in EP 2 458 123 and GB 2 454 355

For closing and freeing large gate passages in a safe and rapid manner, it is known to use so-called folding gates with different panels which are hingedly connected to each other and which can be folded against each other for opening the gate. Guiding and moving the panels of such a folding gate typically require either an upper guide or a lower guide in the ground. An upper guide has the disadvantage that it remains standing during folding and that the height of the gate passage is therefore limited to the height of the upper guide. A bottom guide in the ground has the disadvantage that dirt ends up in the bottom guide. In addition, a folding gate has the disadvantage that safety is limited, since during folding of body parts it can get stuck between two panels of a folding gate. The disadvantages of the top and bottom guides can be partially overcome by using a rod system for moving the panels of the folding gate. A folding gate with a rod system does not have the height problem nor the problem that dirt can penetrate, but the safety problem is not solved. On the contrary, by using a rod system there are even more risks that body parts can be pinched between rods of the rod system.

In addition, there are swing gates where one large panel opens. Such swing gates have the disadvantage that they open and close slowly. There are also sliding gates. However, these require a great deal of space for large passageways, since the entire gate must be pushed aside to clear the passageway.

The present invention has for its object to provide a single and a double gate which meets one or more of the disadvantages discussed above, and in particular a gate which is simple in structure, which is safe, which can be opened relatively quickly , and which can be used multifunctionally.

To this end, the invention provides a gate as claimed in claim 1. The gate comprises: a first closing part which is adapted to be hinged about a vertical axis to a column adjacent to a gate passage, or to another bearing element, such as a wall that borders at a gate passage; a second closure member suspended from the first closure member; a guide between the first and the second closure part, which guide is adapted to guide a movement of the second closure part along the first closure part towards the column for opening the gate and away from the column for closing the gate; a drive adapted to pivot the first and second closing part about the vertical axis, and for moving the second closing part relative to the first closing part towards the column for opening the gate and away from the column for closing the gate.

In this way a gate is obtained which can close a relatively large gate passage and which can be opened and closed relatively quickly by a combination of a pivoting and sliding movement. In addition, the gate is multifunctional in the sense that in some embodiments it is possible to operate the drive such that only a sliding movement or a combined sliding and turning movement is activated, depending on the size of the gate opening that is required. In comparison with folding doors, no guides in the ground or above the closing parts are required. In comparison with existing swing gates, faster opening and closing is possible, and in comparison with sliding gates no space has to be provided in line with the gate to make opening possible.

According to a possible embodiment, the drive comprises a first drive which is adapted to pivot the first and second closing part about the vertical axis; and a second drive adapted to move the second closing member relative to the first closing member toward the column for opening the gate and away from the column for closing the gate. Within the scope of the invention, it is possible that a first and second motor are provided for the first and second drive, respectively, but it is also possible for a common motor to be provided for the drive, whereby both the pivot and translation movement is realized. The first drive preferably comprises a motor which is arranged in the column and which is connected by means of a rod system to the first closing part for pivoting about the vertical axis.

According to a preferred embodiment, the guide and the drive, i.h.b. the second drive adapted to move the second closing part parallel to the first closing part. However, it is also possible for the second closing part to be positioned obliquely with respect to the first closing part and to be displaced at a small angle with respect to the first closing part.

Preferably the drive comprises, i.h.b. the second drive, a motor mounted on the first closing part. It is also possible to mount the motor on the second closing part, but in most embodiments the mounting of the motor on the first closing part will lead to a more stable construction.

In an exemplary embodiment, the second drive comprises a rack and pinion. When the motor is provided on the first closing part, the gear rack can be mounted on the second closing part, and the motor is then intended to rotate the pinion for shifting the second closing part relative to the first closing part. The person skilled in the art understands that the rack can also be provided on the first closing part, and that other drive means are possible within the scope of the invention. For example, the drive may comprise one or more chains, one or more gears, one or more toothed belts, one or more spindles, or a combination thereof, which are coupled to a motor for causing the translational movement of the second closing part. However, the use of a gear rack leads to a simple and stable construction.

In a possible embodiment, the gate further comprises a control for controlling the drive. The control is preferably adapted to activate the drive such that during pivoting of the first closing part, the second closing part is shifted relative to the first closing part. In an exemplary embodiment, the controller is adapted to provide: a first mode in which the second drive is activated and the first drive is not, such that the gate is partially opened; and a second mode in which the first and second drives are activated, for fully opening the gate. In that way the gate can then be dimensioned, for example, in such a way that a partial opening in the first mode is sufficient to allow a cyclist or a pedestrian to pass through but not a car, or is sufficient to allow a car to pass through but not a truck. The gate can further be dimensioned such that a full opening in the first mode is sufficient to also allow trucks to pass. The control is preferably adapted to be operated with user-operating means, such as a remote control or a badge, wherein a first type of user-operating means is provided for activating the first mode, and a second type of user-operating means for activating the second mode.

In a possible embodiment the guide comprises a first guide and a second guide which are adapted to guide the second closing part at a first height and at a second height that is different from the first height, respectively. The first guide can for instance comprise an elongate guide and at least one bearing. The elongate conductor is, for example, mounted on the second closing part. The at least one bearing can then be mounted on the first closing part and be adapted to guide the elongate conductor. The second guide comprises, for example, a guide channel and at least one running wheel, the guiding channel being mounted on one of the first and the second closing part, and wherein the at least one running wheel is attached to the other of the first and the second closing part. The first guide and the second guide can also be similar to each other. The first height at which the first conductor is arranged can be greater or smaller than the second height at which the second conductor is arranged.

In an exemplary embodiment, the first closing part and the second closing part is one of the following: a closing panel, optionally provided with openings; a frame against which a plate is attached; a closing part with bars; a frame in which a mat is tensioned; a frame in which bars are provided.

In a possible embodiment the first closing part comprises a front wall and a rear wall, and the second closing part is movable between the front wall and the rear wall of the first closing part. The second drive can then be active between the column and the second closing part, and between the front wall and the rear wall.

According to yet another variant, the second closing part comprises a front wall and a rear wall, and the first closing part is received between the front wall and the rear wall of the second closing part upon opening of the gate.

The invention further relates to a double port comprising a first single port according to one of the embodiments described above. Preferably, the dual port comprises a second single port according to any of the embodiments described above, wherein the second termination part of the first single port connects to the second termination part of the second single port.

In the first mode, only the second drive of both gate wings is activated and the first drive is not activated, such that the gate is partially opened, see figure 1D. The gate can then, for example, be dimensioned such that such a partial aperture Dj in the first mode is sufficient to allow cyclists and pedestrians to pass through but no carriages, or is sufficient to allow carriages through but no trucks. In a second mode, the first and the second drive 30, 40 of both gate leaves are activated, for full opening of the gate, see figures 1B and 1C. The gate can then be dimensioned in such a way that such a complete opening D2 (see figure 1C) in the second mode is sufficient to also allow trucks to pass.

In a second possible embodiment, the control is adapted to provide at least a first mode, a second mode, a third mode, and a fourth mode. The first and the second mode can be analogous to the first embodiment. In a third mode, only the second drive of one gate leaf is activated, and not the first drive of both gate leafs and also not the second drive of the other gate leaf, such that only half of the aperture Dj of Figure 1D is released. The control can herein be arranged to control only the right-hand gate wing or only the left-hand gate wing in the third mode. The gate can then be dimensioned such that such an opening Dx / 2 in the third mode is sufficient to allow only pedestrians and cyclists to pass through. In a fourth mode, the first and the second drive 30, 40 of one gate wing are activated, and not the first and the second drive 30, 40 of the other gate wing, such that only half of the opening of Figure 1C is released. The gate can then be dimensioned such that such a partial aperture D2 / 2 in the fourth mode is sufficient to allow cars to pass, but no trucks. Here, the control can be arranged to control only the right gate wing or only the left gate wing in the fourth mode.

The control may be provided with a number of buttons for activating the respective modes described above. In addition, the controller 70 may be adapted to be operated with user-operating means, such as a remote control or a badge, wherein a first type of user-operating means may be provided for activating the first mode, and a second type of user-operating means for activating the second mode, etc. In this way it is made possible that certain users can only enter a site on foot or by bicycle, while other users can enter the site by car.
