Description

The invention relates to a parking device with a gate device according to claim 1.

Various gates and locking systems are known from the prior art, in particular to secure parking spaces for vehicles against unauthorized access and external influences. In particular, there are swing, tilt and sectional doors, each of which is moved by a vehicle to open. There are also rolling and folding doors that can be rolled up or folded up above the door opening. However, all of these solutions require space above the vehicle, both for the final position and in the area through which the gate and the drive elements move. Particularly in multiparking systems for space-saving accommodation of several vehicles, such a space is not available, for example in so-called double parkers, duplex parkers or stacked parkers, such as those in DE 20 2019 100 778 U1 to be discribed. Here at least two vehicles are accommodated one above the other in a single parking space, in particular with the help of a movable platform. As a rule, one of the two vehicles can always be removed, but the other can only be removed if there is no second vehicle parked in the parking space. These stackable parkers are increasingly being used in underground car parks where the... usable installation space is fixed. In order to be able to accommodate the largest possible vehicles in a small space, the platform should be designed to be as large as possible. Accordingly, little space is available for the gate device. Side sliding gates can sometimes be used here if a gate segment can be pushed completely to the side out of the access opening, especially if a neighboring second parking space can be integrated into the gate system. However, this cannot be implemented at all for individual parking spaces. To ensure comfortable operation, as few steps as possible should be necessary, especially for operating the gate lock and moving the gate. For example, a lock for a sectional door is off DE 60 2006 000 733 T2 known. This has a lock case and a central bolt.

In the field of window construction are out US 1,751,358 A , US 1,486,653 A Windows that can be pushed upwards in several parts are known. There is also a two-part door that slides upwards US 1,332,956 A known.

DE7911101U1 discloses a storage device.

The object of the invention is to create a technical solution for closing an access opening of a parking space of a parking device, which takes up as little space as possible, allows safe and comfortable operation and can be produced inexpensively in large quantities.

Main features of the invention are specified in claim 1. Refinements are the subject of claims 2 to 14.

The invention relates to a parking device for parking objects, in particular vehicles, at least comprising at least one platform with a storage area which can be positioned by a movement device relative to an access opening, and a gate device which is arranged in the access opening. The gate device for closing the access opening has two vertically aligned guide rails that laterally limit the access opening. Furthermore, it has an outer gate element which is slidably mounted in or on a vertically aligned outer guide of the guide rails. In addition, the gate device has an inner gate element which is slidably mounted in or on an inner guide of the guide rails, which runs parallel adjacent to the outer guide. In this case, in a closed position of the gate device, the inner gate element is arranged in a first region of the access opening, which is lower than a second region in which the outer gate element is arranged. In an open position of the gate device, the outer gate element and the inner gate element are arranged in a third area of the access opening, which is higher than that first and second area. Partial areas of the first and second areas as well as the second and third areas can overlap. The gate device also has a locking element for effecting a locking state in which the locking element locks the displaceable mounting of the inner gate element relative to the two guide rails in the closed position. In addition, the gate device has a coupling element on one of the inner and outer gate elements, which interacts with the other of the inner and outer gate elements in such a way that the locking element ensures the displaceable mounting of the outer gate element in the locked state relative to the two guide rails indirectly via the inner one Gate element blocks.

On the one hand, this allows the access opening to be opened with little space required by simply pushing the inner and outer gate elements upwards. So it is a type of vertical gate. On the other hand, the gate can be conveniently locked by only immediately locking the inner gate element. The inner gate element essentially holds down the outer gate element. Therefore, in a special embodiment, it is provided that the coupling element is designed as a hold-down device in such a way that the inner gate element blocks the outer gate element from moving upwards in at least one operating state. Preferably, the coupling element also interacts with the other one of the inner and outer gate elements in such a way that no gap can be pushed open between the outer gate element and the inner gate element. It is possible that the coupling element is an integral part of the inner or outer gate element. However, it can also be designed separately and fixed to the inner or outer gate element. The gate elements should only be able to move linearly, namely by moving them and especially in the vertical direction. This means that free space is only necessary for their movement in the direction of movement of the gate elements. The outer gate element should not be able to be pushed into the first area. For this purpose, a stop is preferably formed on at least one of the guide rails, on which the outer gate element sits in its lowest position. The gate device keeps the storage space of the storage device as free as possible for objects that are arranged on and under the platform.

The installation and movement space of the inner and outer gate elements is preferably less than 120 mm, more preferably less than 100 mm and particularly preferably less than 80 mm in depth perpendicular to the gate elements. The gate device therefore hardly restricts an available storage space, for example a passenger car parking space. Accordingly, larger platforms and passenger cars, for example, can be accommodated in the storage space.

To achieve the locked state of the inner gate element, it is advisable to provide at least one locking point along the inner guide in at least one of the guide rails, with which the locking element can be brought into engagement. To ensure that the inner gate element does not simply fall down if a drive is damaged, it is also possible for several locking points to be arranged distributed along the inner guide, with which the locking element can be brought into engagement in different positions of the inner gate element. The rest points can be recesses, holes, punched outs or troughs. It is possible to extend the locking point in the direction of the inner guide, which is larger than required by the locking element, for example elongated holes. This means that the locking element can be brought into engagement with the locking point even at higher movement speeds of the inner gate element. No rest areas need be provided along the outer guide. According to a special embodiment, the coupling element interacts with the other of the inner and outer gate elements in such a way that the inner gate element is at least 50%, preferably at least 60%, more preferably at least 70% and particularly preferably at least 80% next to (or viewed from). at the front behind) the outer gate element can be pushed. This has the advantage that a relatively large part of the access opening can be released without, for example, the gate elements having to be pivoted.

The coupling element is advantageously designed as a driver in such a way that the inner gate element takes the outer gate element along in at least one operating state. In this operating state, only the inner gate element needs to be actuated.

In an optional embodiment, it is provided that the coupling element interacts with the other of the inner and outer gate elements in such a way that the inner gate element pushes the outer gate element from the second region into the third region when it is moved into the third region. An actuating force that only acts on the inner gate element is therefore sufficient for opening and closing the gate device.

Optionally, it is provided that the coupling element is a rigid, immovable element that is formed or arranged on the inner or outer gate element. This is easy to implement in terms of construction, inexpensive and permanently stable and wear-free.

In principle, it is possible for the coupling element to have several individual elements arranged distributed over the distance between the two guide rails. This increases the transferable force and distributes it across the width of the gate elements.

Another option is for the coupling element to engage behind the other of the inner and outer gate elements in the closed position, preferably similar to a hook, and preferably in such a way that the inner and outer gate elements can only be bent together. This increases burglary security.

According to a more detailed embodiment, the coupling element is arranged on the inner gate element, preferably in the area of its upper end. In particular, all mechanical structures of the coupling means can be formed on the inner side of the gate elements. This means that they cannot be manipulated by unauthorized access from outside and are also concealed.

In a special embodiment, the coupling element projects from behind between an upper and a lower frame profile of the outer gate element in such a way that in the closed position it is arranged adjacent, in particular on the top side, to the lower frame profile and in the open position it is arranged adjacent, in particular on the underside, to the upper frame profile . This means that the coupling element can act as a hold-down device on the lower frame profile and as a driver on the upper frame profile. The coupling element should be freely movable between the lower and upper frame profile.

For a high level of operating comfort, it is optionally provided that the inner gate element is driven with a lifting drive to be displaceable along the inner guide.

It can be provided that the lifting drive has a motor, which is preferably arranged in the height range of the two upper ends of the two guide rails. Automated opening is possible with a motor.

In addition, the lifting drive can have a chain, preferably a roller chain, which is fixed to the inner gate element. This can be arranged to save space and can in particular simply be guided vertically upwards above the inner gate element. Chains also allow a simple non-elastic coupling, including the option of changing direction.

In one embodiment variant, the outer gate element is driven exclusively indirectly via the inner gate element with the lifting drive. This allows a less complex implementation of the gate drive.

The gate device can be supplemented in such a way that it has an emergency unlocking device with which the locking state can be canceled manually, especially to be able to manually push the inner gate element upwards. This means that, depending on the application, safety regulations for emergency opening can be met. The emergency release device preferably has an actuating element on the inside of the gate device. This allows a trapped person to free themselves. Optionally, the blocking state can be detected with a sensor or switch. This information about the locking state can be used, for example, with a control unit of the lifting drive, or also by an alarm system.

In particular, the locking element can be kinematically coupled to the lifting drive in such a way that the locking element automatically assumes the locked state in the closed position and when the lifting drive is relieved of load. This means the gate is automatically locked when it is moved to the closed position. Preferably, this coupling is also designed to act in the opposite direction, namely in such a way that the application of a lifting force with the lifting drive removes the locking state of the locking element and then sets the gate element into the displacement movement.

A special locking device is optionally provided for this purpose. Such a locking device for locking gate elements can have a housing as well as a trigger element and a locking element. The triggering element and the locking element are kinematically coupled to one another in such a way that the locking element assumes a locking state in the unloaded state of the triggering element and an unlocking position when the triggering element is loaded with a tensile force, a lifting element being provided with which the tensile force can be applied to the triggering element or is applied, the tensile force preferably acting geodetically vertically upwards.

In a special embodiment of the locking device, the locking element is moved into a locking position in the locking state or strives (at least) in the direction of this locking position, the locking element preferably protruding from a first side of the housing in the locking position.

The housing of the locking device should be fixed to the inner gate element, with the locking element in the locking position engaging the guide rail in such a way that displacement of the inner gate element along the displaceable bearing is blocked, and the locking element in the unlocking position being arranged so that a Displacement of the inner gate element along the displaceable bearing is released.

This ensures that the locking state is present permanently without any actuating force being applied. On the one hand, the tensile force allows the lock to be released and, on the other hand, tension can be applied directly to the housing, which ultimately allows the inner gate element, which can be connected to the locking device, to move with it. Consequently, only one movement action is necessary for unlocking and moving, namely the pulling force. Optionally, this can be applied manually or using a drive. The lifting element is preferably designed to be non-rigid. In particular, the lifting element is, for example, a rope, a wire, a chain or in particular a roller chain. The lifting element can be connected directly to the triggering element, or a rigid intermediate part is arranged between the non-rigid lifting element and the triggering element.

In a special embodiment of the locking device, the locking element is moved into a locking position in the locking state or strives (at least) in the direction of this locking position, the locking element preferably protruding from a first side of the housing in the locking position. As a result, the locking element can engage in a counterpart, in particular in one of the guide rails, and block movement of the locking device in the direction of the tensile force. The striving of the locking element is to be understood as meaning a load on the locking element which leads to the locking state, as long as the locking element is not hindered in its movement by third parts. This is the case, for example, when individually and distributedly arranged locking points are provided on a guide rail. In the locking position, the locking element preferably protrudes from the first side of the housing transversely to the tensile force. The locking element is preferably arranged to a greater extent in the unlocking position than in the locking position or completely within the housing. Through this position, the locking element enables movement of the entire locking device in the direction of the tensile force, especially when there is no longer any engagement with a counterpart that would block this movement.

According to a special embodiment, the locking element is put into the locking state by gravitational forces and/or a spring force when the trigger element is in the unloaded state. The locking state is therefore maintained even if drives fail or any power supply is interrupted. Preferably, in the unloaded state of the release element, the locking element is held in the locking state essentially by the spring force and additionally by the gravitational forces. This means that the locking state is maintained even if the spring is damaged. The Gravitational forces can, for example, act directly on the locking element, or can act indirectly on the locking element via the triggering element.

Furthermore, the trigger element can be held in the locked state in the unloaded state by gravitational forces and/or a spring force. This ensures that no unlocking occurs in the event of a drive failure or a power interruption.

In a special version, the spring force is caused by a spring, preferably a spiral spring. The spiral spring is preferably pushed onto the locking element. This means it is securely guided and held in position. If a spiral spring is used, its wire diameter should be larger than the distance between the turns. In the event of a spring breaking, this prevents the two fragments from pushing and/or screwing into one another, so that even then the function of the spring is largely retained. In general, the spring force should be designed such that the spring moves the locking element into the locking position and/or holds it there when the trigger element is relieved. Furthermore, it is possible to design the spring force of the spring in such a way that the trigger element is moved into the unlocking position with the tensile force before the tensile force exceeds the weight of the locking device and the inner gate element connected to it. In particular, the spring force of the spring can be designed such that the locking element leaves the unlocking position when the weight of the locking device and the inner gate element falls below a safety value, in particular, for example when the locking device or the inner gate element hits an object. In other words, the locking element can be extended if contact occurs, for example if the inner gate element collides with a person. By designing the spring force based on the weight to be lifted, the counterforce that must act from below against a gate element can be defined until the locking element is put into the locking state. This counterforce is preferably only a fraction of the actual gate element weight. Actively detecting safety edges on the lower edge of a gate element can be completely dispensed with. Optionally, it can be provided that the spring force of the spring is designed to be adjustable. This can be done, for example, with an adjustable spring seat, or washers/washers for the spring seat, or simply with a set of replacement springs with different spring forces. This allows the spring force to be individually adjusted to the weight of a gate element.

The locking element is preferably mounted in the housing so that it can be moved linearly. Such storage is stable and locks accordingly resistant to unauthorized opening. The Optional spring can, for example, sit on the locking element and be clamped between a spring seat of the locking element and a linear bearing fixedly arranged in the housing. In a special embodiment, the trigger element is coupled to the locking element via a mechanical transmission. This results in a robust and error-prone active connection for the actuation. In particular, the triggering element can be a pivotally mounted actuating rocker. With this, a force can be redirected in a simple, constructive manner, for example from a vertical direction of force to a horizontal direction of force. Furthermore, the triggering element can be coupled to the locking element via a link guide. In the simplest case, the backdrop of the backdrop guide is a straight slot.

Furthermore, it has proven to be advantageous if the locking element abuts a stop in the unlocking position and the tensile force is at least partially introduced into the housing by the triggering element via the stop. This achieves a defined end position. Additionally or alternatively, the triggering element can strike a stop in the unlocking position and the tensile force is at least partially introduced into the housing by the triggering element via the stop. On the one hand, this reduces the load on the kinematic coupling between the locking element and the release element, and on the other hand, the tensile force is redirected for a further task, in particular the opening of a gate element, namely into the housing as a stable structure that can be fixed to such a gate element. Accordingly, the locking element is then not subjected to such a heavy load.

For safety reasons, an addition is recommended whereby the locking device has a sensor or a switch that detects at least one possible position of the locking element, preferably the unlocking position. The detection of this position can be transmitted to a control unit, for example.

In a special design, the housing is cuboid-shaped, being longer than it is high and higher than it is deep, whereby the housing forms three pairs of side surfaces of different sizes, with the largest pair of side surfaces having a front and a back, the medium-sized pair of side surfaces having a top and a bottom, and the smallest pair of side surfaces forms two opposite end faces. Such a flat housing can be attached to or integrated into the inner gate element in a particularly compact manner, which as such usually also has a flat cuboid outer contour. For this purpose, the housing should be at least twice as high as it is deep. A shape is also possible in which the housing is at least twice as long as it is high.

According to a more detailed embodiment, the locking element is arranged in the area of one of the two end faces. This means that the locking element lies on one of the smallest two sides and the larger two pairs of sides are available for a stable connection to a gate element.

It can be provided that the housing has fastening holes or fastening elements on the underside with which the housing can be secured to a surface, in particular to the inner gate element or its gate profile.

Furthermore, it is advantageously provided that the trigger element is arranged in the area of the top of the housing so that it can be actuated from outside the housing. The locking device is therefore particularly suitable for gate elements such as the inner gate element, which is to be pulled upwards, in particular with the tensile force acting on the trigger element.

The housing preferably forms a storage area for the lifting element in the area adjacent to the trigger element. In the locked state, a section of the lifting element can be placed on the storage surface of the housing. This ensures that no more tension acts on the triggering element and the locking element is not held in the unlocking position. In addition, the defined storage ensures that the lifting element carries out a defined movement during or before the application of the tensile force until it finally applies the tensile force to the triggering element.

Furthermore, an emergency unlocking device that can be actuated from outside the housing can optionally be kinematically coupled to the locking element in such a way that the locking element can be moved into an emergency unlocking position by manual actuation of the emergency unlocking device, the emergency unlocking position preferably corresponding to the unlocking position. This means, for example, that a trapped person can free themselves. A lever can be provided to overcome the force acting in the locking state. The lever can optionally also be positioned at a distance from the housing and can interact with the locking element, for example via a wire pull or Bowden cable.

Furthermore, it is advantageously provided that a projection protrudes beyond the housing, which can be used in particular in the transverse direction to the locking element and preferably also in the transverse direction to the release element and preferably as a hold-down device and/or as a driver. This projection serves as a coupling element of the gate device usable. This projection can restrict the movement of the other gate element, for example hold it down, or it can pull the additional gate element with it. In particular, the projection should protrude beyond the front of the housing. In addition, the projection in the underside area should protrude beyond the front of the housing. As a result, a second gate element can be carried at least almost congruently with the first gate element to which the housing is connected. The access opening is thus opened to the maximum extent.

Further features, details and advantages of the invention emerge from the wording of the claims and from the following description of exemplary embodiments based on the drawings. Show it:

Fig. 1 shows a perspective oblique view of a parking device 70 with two adjacently arranged gate devices 1. The parking device 70 is used to park vehicles and has two platforms 73, each of which are arranged next to one another and can be positioned relative to an access opening A by a movement device 71, each with a storage area 74. One of the two gate devices 1 is arranged in the access openings A.

In the following, only one of the two gate devices 1 will be described because they can be designed to be identical anyway. How to get in Fig. 1 in conjunction with the schematic sketches of the Fig. 2 , 3 and 4 As can be seen, the gate device has two vertically aligned guide rails 2, 3, which laterally limit the access opening A. An outer gate element 20 is slidably mounted in or on a vertically aligned outer guide 4 of the guide rails 2, 3. An inner gate element 30 is slidably mounted in or on an inner guide 5, which runs parallel adjacent to the outer guide 4. The inner guide 5 is also formed by the guide rails 2, 3.

The inner gate element 30 is arranged in the closed position SG of the gate device 1 shown in each case in a first area B1 of the access opening A, which is lower than a second area B2 in which the outer gate element 20 is arranged. The outer Gate element 20 and the inner gate element 30 are in an open position (see reference symbol SO in Fig. 4 ) of the gate device 1 is arranged in a third area B3 of the access opening A, which is higher than the first and second areas B1, B2. Like in the Fig. 2 and 4 can be seen, the first and second areas B1, B2 and the second and third areas B2, B3 overlap.

With the in Fig. 3 illustrated locking element 40 of a locking device 39, a locking state S can be brought about in which the locking element 40 locks the displaceable mounting of the inner gate element 30 relative to the two guide rails 2, 3 in the closed position SG.

Furthermore, the gate device 1 has one in the Fig. 2 and 4 schematically illustrated coupling element 50, which can be arranged on one of the inner and outer gate elements 20, 30, and in the present case is arranged at the upper end of the inner gate element 30. The coupling element 50 interacts with the outer gate element 30 in such a way that the locking element 40 blocks the displaceable mounting of the outer gate element 20 in the locked state S relative to the two guide rails 2, 3 indirectly via the inner gate element 30. The coupling element 50 is therefore designed as a hold-down device. Stops on the guide rails 2, 3 with which the outer gate element 20 is blocked from moving into the first area B1 are not shown.

How to get into the Fig. 2 and 4 can further see, the coupling element 50 interacts with the outer gate element 20 in such a way that no gap can be pushed open between the outer gate element 20 and the inner gate element 30. Rather, the coupling element 50 interacts with the other of the inner and outer gate elements 20, 30 in such a way that the inner gate element 30 can be pushed at least 50% next to (or behind, viewed from the front) the outer gate element 20. In addition, the coupling element 50 interacts with the outer gate element 20 in such a way that when the inner gate element 30 is moved into the third area B3, it also pushes the outer gate element 20 from the second area B2 into the third area B3. The coupling element 50 is therefore designed as a driver. For this purpose, the coupling element 50 is designed as a rigid, immovable element which is formed or arranged on the inner gate element 30. From here, the coupling element 50 protrudes from behind between an upper and a lower frame profile 21, 22 of the outer gate element 20 in such a way that in the closed position SG it is arranged on the top side adjacent to the lower frame profile 21 and in the open position SO it is arranged on the underside adjacent to the upper frame profile 22 is. The coupling means 50 can easily be pushed past the outer gate element 20 between the upper and lower frame profiles. Optionally, the coupling element 50 have several individual elements arranged distributed over the distance between the two guide rails 2, 3, which could, for example, also be designed to be identical in construction.

According to the schematic sketches Fig. 2 and 3 A lifting drive 60 can also be removed. In particular, the inner gate element 30 is driven by the lifting drive 60 to be displaceable along the inner guide 5. The lifting drive 60 has a motor 61 which is arranged in the height range of the two upper ends of the two guide rails 2, 3. The motor 61 drives a chain 62 of the lifting drive 60, which is attached to the inner gate element 30, according to Fig. 3 in particular indirectly via the locking device 39. In contrast, the outer gate element 20 is driven exclusively indirectly via the inner gate element 30 with the lifting drive 60.

The special embodiment shown Fig. 3 provides that the locking element 40 is kinematically coupled to the lifting drive 60 in such a way that the locking element 40 automatically assumes the locking state S in the closed position SG and when the lifting drive 60 or its chain 62 is relieved. If the lifting drive 60 is activated and the chain 62 is tensioned, the locking element 40 unlocks.
