Description

PARKING PLATFORM

The invention relates to a parking platform for a parking system with a drainage device.

A number of parking systems are described, for example, in the company brochure 8M6.95/GA ST from Otto Wöhr GmbH. Such parking systems, such as parking lifts, parking plates with transverse/longitudinal displacement, corridor parkers or parking safes, comprise parking platforms on which vehicles can be parked. In order to drain liquids running off parked vehicles, for example snow or meltwater, a drainage system must be provided for a parking platform.

The invention is based on the object of designing a parking platform in such a way that drainage of the parking platform is achieved in the simplest possible way.

This object is achieved according to the invention in a parking platform of the type mentioned at the outset in that the drainage device has at least one collecting trough and that a collecting trough is provided with at least one drainage opening for the targeted drainage of water.

The sanitary tub provided according to the invention allows the water to be collected in a targeted manner and then further drained through the at least one drainage opening, i.e. disposed of at a specific, predefined location. In this way, good drainage can be achieved without having to provide permanent drainage, which would entail increasing the height of a parking platform. Since parking systems with parking platforms are generally used where the available space is limited and therefore valuable, a parking platform according to the invention achieves cost-effective drainage, since the height of the parking platform does not need to be increased.

The device according to the invention has the further advantage that fire protection is considerably improved. Parking systems are usually equipped with an extinguishing system, with one or more sprinklers assigned to each individual parking platform. In the event of a fire, one or more sprinklers are activated when a predetermined temperature is reached. However, there is a risk that petrol leaking from the vehicle will be washed over the parking platform with the extinguishing water to other parking platforms. This includes the risk that the fire will spread further due to the spread of the flammable liquid. With appropriate dimensioning, in particular of the drainage opening or the drainage openings on a collecting tray, it is possible to achieve that, in accordance with the maximum possible and previously determined

A 55 192 u

10 September 1999

With a maximum rate of fire extinguishing water from sprinklers being applied to a collecting tray, so much fire extinguishing water is always drained from a collecting tray via the drainage opening or openings that fire extinguishing water cannot escape over the edges of the collecting tray and thus over the parking platform onto neighboring parking platforms, taking the petrol with it. The flammable liquid is thus kept on the parking platform and the fire remains localized on the parking platform where it broke out until it is extinguished.

Advantageously, a drainage opening is arranged on the collecting trough at or near a lowest point of the collecting trough in relation to a horizontal position of the parking platform. As a result, the drainage opening is at the lowest possible gravitational potential on the collecting trough, so that good drainage is ensured. Advantageously, a drainage opening is arranged in a wall of the collecting trough at a base of the collecting trough.

From a structural point of view, it is particularly advantageous if a collecting trough is formed in a channel for a vehicle to be parked. The channel itself represents a depression in the parking platform, which can then be used to collect the water, especially since it has a relatively large surface area.

It is advantageous to have a discharge opening in relation to an entry direction at the centre or near

A 55 192 u

10 September 1999

the middle of the fairway. This area is or can easily be placed at the lowest gravitational potential, since the design options here are not as high as in other areas due to the structural requirements for supporting the vehicle. In particular, this middle area can be designed as a depression - also in relation to the longitudinal direction of the fairway.

In order not to increase the external dimensions of a parking platform, it is advantageous to arrange a drainage opening on one fairway facing an opposite fairway. This drains the water inwards.

It is particularly advantageous if a collecting trough comprises a bottom area which is lower than the rest of the bottom area and in which the drainage opening is arranged. This means that the channel for the vehicle only needs to be slightly modified in order to form it as a collecting trough, since the drainage opening can be arranged in the lower bottom area at the lowest gravitational potential in relation to the entire collecting trough, and it is also ensured that water from the rest of the collecting trough itself flows into the lower bottom area and thus essentially all of the water can be drained from the collecting trough.

It is particularly simple in terms of construction if the lower floor area is formed by a channel in the collecting tray.

In order to dispose of the water at a specific location, a drainage element is located at a drainage opening for the targeted drainage and disposal of the collected water. This disposal point can be easily adjusted by appropriate design and dimensioning of the drainage element. In particular, disposal can then also take place at a distance and at a location from the drainage opening.

It is particularly advantageous if an end of the drainage element facing away from the drainage opening of the collecting trough is positioned or can be positioned at a height relative to the bottom of the collecting trough which is below an upper level of the collecting trough. As a result, water up to a certain level, which is determined by the height of an opening of the drainage element relative to the collecting trough, is not drained away but remains in the collecting trough until it evaporates there, for example. If this level is exceeded, however, water is drained away via the drainage element or, in the case of several drainage openings, via the drainage elements until the specified level is reached. The height can therefore also be used to set the amount of collected water at which water should begin to be drained from the collecting trough.

In a variant of an embodiment, it is provided that the end of the discharge element is movable in the vertical direction relative to a horizontal position of the parking platform in such a way that the end can be brought below a level of the bottom of the collecting trough. This makes it possible for the collecting trough to be essentially completely emptied when the end is brought below the bottom of the collecting trough. On the other hand, however, complete emptying can be brought about in a targeted manner if the end of the discharge element is moved accordingly. This makes it possible to set different operating conditions, in particular an operating condition of complete emptying and an operating condition of accumulation of water in the collecting trough up to a certain level.

Advantageously, actuating means are provided to cause the end of the discharge element facing away from the discharge opening to move in a vertical direction. The actuating means can be operated manually, for example in the form of a guide for a corresponding rod, in order to empty the collecting tray as required (for example before repair work on the parking platform or for cleaning the parking platform) or can also be operated automatically, for example with a servomotor; for example, a collecting tray can be emptied when the parking platform is moved on a guide track or during this movement.

In a variant of an embodiment, the discharge element comprises a pipe element. This allows the collected water to be disposed of at a specific location in a structurally simple and cost-effective manner.

The end of the discharge element can be made mobile in a simple manner by having a hose element at the end of the pipe element facing away from the discharge opening. The hose element is designed to be particularly flexible so that a mouth opening can be brought below the level of the base of the collecting trough and, on the other hand, so rigid that the mouth opening remains above this level without any force being applied to the hose element.

In a further variant of an embodiment, the pipe element is arranged at an angle upwards in relation to the bottom of a collecting tray. This makes it possible to set a height level for the collecting tray in a simple and cost-effective manner, and if the collected water exceeds this level, water is drained through the drainage opening or openings until the set level is reached again.

In a further embodiment, the pipe element comprises a pipe bend which is connected to one of the discharge

The end facing away from the opening is arranged in such a way that water can be drained downwards in a vertical direction.

It is particularly advantageous if the drainage opening or drainage openings of a collecting tray are dimensioned in such a way that the resulting liquid flow through the collecting tray via the at least one drainage opening prevents the collecting tray from overflowing at a predetermined liquid loading rate of the collecting tray. Depending on the height of a mouth opening of the drainage element (in its non-forced position), it can then be achieved that water from the collecting tray is essentially only drained via the drainage opening, so that the collecting tray cannot overflow. This prevents petrol collecting in the collecting tray from flowing upwards out of the collecting tray onto other parking platforms. In the event of a fire, the drainage device according to the invention prevents the fire from spreading through the parking system. Since extinguishing water is constantly supplied from above via sprinklers and petrol floats on top of the water, the extinguishing water drained via the drainage opening or drainage openings is largely free of petrol. A collection volume of a collection tray, from which no water is yet drained, can preferably be set such that it exceeds the typical capacity of a petrol tank of a motor vehicle.

Figure 5: a detailed view of a third embodiment of a drainage device.

In an embodiment of a parking platform, which is shown in Figures 1 and 2 and is designated there as a whole by 10, a parking area 12 for a vehicle 14 is formed between a first outer support 16 and a second outer support 18. The supports 16 and 18 are preferably I-Pro-

filträger. Cross beams (not shown in the drawing) can be arranged between the outer beams 16 and 18. The outer beams 16 and 18 and the cross beams hold a surface structure 20 to form the support surface 12.

At opposite ends 22 and 24 (Figure 2), the parking platform 10 is provided with a pair of rollers 26 arranged at a distance from one another, by means of which the parking platform 10 is displaceable on a guide track 28 which is formed by a pair of guide rails 30, 32 arranged at a distance corresponding to the length of the parking platform 10.

The surface structure 20 comprises two channels 34 and 36 arranged parallel to the outer supports 16 and 18 and spaced apart from one another. A channel 34 or 36 has a front area 38, a middle area 40 and a rear area 42. The front area 38 and the middle area 42 are on one level such that a vehicle can drive onto or off the parking platform. The middle area 40, on the other hand, is lowered compared to the front area 38 and the rear area 42. As a result, a support 44 for the front wheels of the vehicle, for example, is formed between the middle area 40 and the front area 38, and a support 46 for the rear wheels of the vehicle 14, for example, is formed between the middle area 40 and the rear area 42 when the vehicle is approaching from the rear area 42.

drives forward onto the parking platform 10. By appropriately dimensioning the front area 38 and the rear area 42, it can be ensured that when the wheels of the vehicle 14 are in the middle area 40, the vehicle body does not protrude beyond the ends 22 and 24 of the parking platform 10 and thus does not represent an obstacle when the parking platform 10 is moved onto the guide track 28.

To form a drainage device, the middle region 40 of the channel 34 or 36 is shaped like a trough, so that a collecting trough 48 is formed, from which water can be collected and in which water can accumulate. The collecting trough 48 has a base 50 which is also oriented essentially horizontally when the parking platform 10 is in a horizontal position. In order to provide a larger collecting area, opposite walls 52 and 54 of the collecting trough 48 are inclined outwards with respect to a vertical direction 56 (which in turn is related to a horizontal position of the parking platform 10). In the base 50 itself, a channel 58 is arranged along the collecting trough 48 at the wall 52 which faces the opposite channel. The channel 58 has a base 60 which is essentially parallel to the base 50 of the collecting trough 48, but is lowered relative to it. Between the bottom 60 and the bottom 50 there is a wall 62 which runs obliquely to the vertical direction 56. As a result, the lowest area of the collecting trough 48 is the channel

One or more drainage openings 64 are arranged on the collecting trough 48 in the area of the channel 58, through which water can be drained from the collecting trough 48 via the channel 58. In the embodiment shown in Figure 1, the collecting trough 48 formed in the channel 34 has a drainage opening 64. In order to enable a largely complete drainage of water from the collecting trough 48, i.e. in order to place the drainage opening 64 at the lowest possible gravitational potential, it is arranged at the bottom 60 of the channel 58 in the wall 52. Preferably, the discharge opening 64 is located at or near the center of a channel 34, 36 with respect to the longitudinal direction of such a channel, since in this way the discharge opening is also arranged in a depression with respect to the longitudinal direction in a simple manner if the bottom 50, 60 of the collecting trough 48 is designed to be slightly inclined towards the discharge opening.

The drainage opening 64 is oriented towards the adjacent fairway so that water can be drained into the area below the surface structure 20 between the fairways 34 and 36.

At the discharge opening 64 there is a discharge element 66 which has a mouth opening 70 at one end 68 from which discharged water can flow out.

In the variant of a first embodiment shown in Figure 1 and Figure 3, the discharge element 66 comprises a rigid pipe element 72 which is arranged horizontally

Direction at the discharge opening 64. At an end 74 facing away from the discharge opening 64 there is a flexible hose piece 76, connected for example via a screw connection or a coupling, which in a non-force-loaded position 78 is oriented upwards so that the end 68 with the mouth opening 70 lies above the pipe element 72 and above the base 50.

By applying force, for example by means of an adjusting rod which can be motor- or hand-operated, the hose section 76 can be moved downwards in the vertical direction 56 in such a way that the mouth opening 70 can be brought below the pipe element 72 or at least below an upper wall 80 of the pipe element 72 and thus below the base 60. In such a force-applied position 82, water can largely completely drain out of the collecting tray 48.

The tubular element 72 is preferably supported by a support 84 connected to the collecting trough 48.

In a variant of a second embodiment, which is shown in Figure 4, the discharge element 66 comprises a cylindrical tube element 86 which is arranged at an angle to the base 50 and is oriented upwards. The end 68 with the mouth opening is located above the base 50 of the collecting trough and below an upper collecting trough level 88.

In a variant of a third embodiment of a drainage device according to the invention, which is shown in Figure 5, the discharge element 66 comprises a rigid cylindrical pipe section 90 which adjoins the discharge opening 64 and is connected to a 90° bend 92, which in turn is connected to a 180° bend. The end 68 with the outlet opening 70 is thus oriented downwards in a vertical direction. The support 84 serves to hold the pipe section 90. The discharge element 66 can be formed in one piece by the pipe section 90 and the bends 92 and 94. The outlet opening 70 is located above the bottom 50 of the collecting trough 48 and below its uppermost collecting trough level 88.

Preferably, depending on the arrangement of the mouth opening 70, the diameter of the discharge opening 64 - or of the discharge openings if several such openings are provided - is dimensioned such that, at a predetermined liquid loading rate of the collecting tray 48, a liquid flow through the collecting tray 48 is set such that overflow of the collecting tray 48 is prevented.

This is particularly advantageous in connection with preventing the spread of fire beyond a parking platform with a flammable vehicle when a sprinkler extinguishing system is in operation. A typical value for the capacity of a collecting pan 48 is in the order of 300 l. Typical values of the flow rate through a sprinkler head of an extinguishing system are in the order of

·

A 55 192 u

10 September 1999

of the order of about 60 to 120 liters of extinguishing water per minute. Since not all of the extinguishing water reaches the collecting pan 48, the liquid loading rate of the collecting pan 48 is generally smaller than the flow rate through the sprinkler head. For a given height of the outlet opening 70 above the base 50 of the collecting pan 48, the diameter of the drainage opening 64 or the diameters of the drainage openings 64, if several such openings are provided, must be dimensioned such that so much water cannot collect in the collecting pan 48 that it overflows over its edge into the support surface 12.

The parking platform 10 according to the invention can be drained as follows:

After parking a vehicle 14 on the parking platform 10, water may run off of it, for example after driving in the rain or when the vehicle is covered in snow. The water collects in the collecting trays 48. The outlet opening 70 is located above the bottom 50 of the collecting tray 48 in the non-forced position 78 according to the first embodiment according to Figure 3 and according to the second and third embodiment according to Figures 4 and 5. As soon as the liquid level in the collecting tray 48 reaches the height of the outlet opening 70, water can flow off via the drainage opening 64 and the drainage element 66 until the outlet opening 70 and the liquid level in the collecting tray 48 are at the same level. By appropriately orienting the drainage element 66

- 16 -

A 55 192 u

10 September 1999

the water flowing out of the collecting tray 48 can be drained off at a specific location via the end of the outlet opening 70 and disposed of there.

In the first embodiment according to Figure 3, the collecting trough 48 can be largely emptied by moving from the non-force-loaded position 78 to the force-loaded position 82. This can also be done automatically by operating an actuating element, such as an actuating rod, for example at regular intervals so that it guides the hose section 76 into the force-loaded position 82, in which the mouth opening 70 is below the bottom 60 of the channel 58.

The parking platform 10 according to the invention enables a high level of fire safety to be achieved. Parking systems equipped with such parking platforms usually have sprinkler extinguishing systems that automatically activate when a predetermined temperature is exceeded. The sprinklers triggered by this pour extinguishing water onto the parking platform 10, which leads to extinguishing water building up on the parking platform 10. If flammable liquids, particularly petrol, leak from the vehicle, these flammable liquids can be washed onto neighboring and particularly underlying parking platforms if the extinguishing water flows over the parking platform after it has built up in the collecting tray and has reached the edge of the platform.

With appropriate dimensioning of the discharge opening 64 and adaptation to the flow capacity of a
Sprinkler system, however, it can be achieved that extinguishing water accumulating in the collecting tray 48 is always drained away to such an extent that it cannot flow beyond the edges of the collecting tray 48 onto the parking area 12 or the surface structure 20 and in particular cannot flow beyond the edges of the parking platform 10 onto adjacent and
to the parking platforms below. This prevents the vehicle from
A fire that has started can spread sideways or downwards via the petrol that has been washed along. The drainage device according to the invention therefore ensures that the fire remains essentially localized to the parking platform 10.
