Abstract

Hanging car park device which enables to park more cars in very less area. The device is very economical compared to other existing facilities. It is basically a rotating system providing parking in hanging garages through set of single link chain, sprockets, electric motor providing drive through set of reduction gears. Wheels provided in every alternate link of the chains are guided by the guide rails provided on the structural pillars prevent lateral swing of hanging garages. The floor of garage and lifting plate on hydraulic jack are so designed that any one pair of wheels at least (Front or Rear) is locked to prevent forward or backward movement of the car parked. This device can be transferred to any desired new location in which case foundation only will have to freshly made there.

Description

HANGING CAR PARK

This invention relates to car parking facilities Presently following systems are in use i) ^• Lift parking facility where central lift with car parking on both sides is provided ii) Underground parking for multi storeyed buildings iii) Parking facility at alternate floors

Following are draw backs with above systems i) All of them are very expensive ii) In many cases valuable FSI is sacrificed iii) These facilities have fixed location which cannot be altered when needed iv) In many cases movement of other cars parked is needed.

Handing Car Park counters above draw backs as under: i) Extremely economical as compared to above facilities. ii) In 6 Mtr x 6 Mtr area, 20 Cars can be parked iii) Location could be any; where open space with height is available. Even more than 20 cars can be parked if required height is available iv) The facility can be transferred to any other desired location on new foundation v) Eliminates need to move other cars in parked area

Hanging car park comprising four pillars structure on solid foundation, set of single link chains, sprockets load bearing shafts each with hanging garage. Connecting to link chains at each end with wheels on each alternate link of the chain engaged with guide rails on the pillars to prevent lateral swing of the hanging garages, electric motor with set of reduction gears to provide drive to sprockets and chains. Turn table which turns car by 90 degrees to facilitate parking/exit of the car. Hydraulic jack to lift floor of hanging garage to ground level,

The basic concept is to have a pair of chains over the sprockets supported by four pillar structure to rotate the chains and hanging garages which are supported by load bearing shafts connecting the pair of chains. Wheels are provided on every alternate link of the chains. These wheels are engaged with guide rails supported by plate on the pillars. Electric motor provides drive through set of six reduction gears to sprockets at the top.

In this device i) Duplex or Triplex link chain could be used ii) Structural pillars could be of any other design and sections iii) Load bearing shaft which is 2" dia pipe reinforced with square plates and 10 mm dia round bars could be of any other design iv) Alternate suitable methodology instead of wheels and guide rails could be provided to prevent lateral swing v) Hanging garages could be of any other suitable material, shape and design vi) Hydraulic motor or variable speed DC motor could be used for providing drive. To assist with understanding the invention reference now will be made to accompanying drawings, which show one example of invention.

Brief description of drawings

Fig 1 Shows the general assembly of the hanging car park, where 1 is pillar structure, 2 is single link chain, 3 is sprockets and 4 is hanging garage.

Fig 2 shows Top view of load bearing shaft assembly with hanging garage fitted to the shaft, where 1 is collar on end shaft, 2 is wheel on each load bearing shaft end connections and also in every alternate link. 3 is guide rails, 4 is link chain, 5 is supporting plate for guide rails, 6 is end shaft at both ends with load bearing shafts and also in every alternate link of the chain, 7 is the coupling connecting end shaft with load bearing shaft (2"dia pipe reinforced with square plates at 10 mm dia round bar welded at each corner of square plate. )

Fig 3 shows front view assembly of Load bearing shaft with hanging garage fitted to the shaft where 1 is the hanging garage, 2 is the floor of hanging garage which has one pair of car wheels locking arrangement (either front wheels or rear wheels) to prevent forward and backward movement of the car in the hanging garage. 3 is the hydraulic jack having plate 4 welded to lift the floor of hanging garage to ground level.

Fig 4 shows sprocket - 1 is the sprocket on which the chain rotates. There are 2 sets each of 6 sprockets on two link chains.

Fig 8 shows drive arrangement plan view at the Top of the structure where 1 is electric motor, 2 is coupling, 3 is connecting shaft, 4 is 8" reduction gear, 5 is 6" reduction gear, 6 is housing for sprocket, 7 is sprocket, and 8 is hanging garage.

Detailed description of preferred embodiments

Referring to drawings fig 1 to fig 8 can be seen that the hanging car park device according to this invention comprises 4 pillar structure with 2 sets of chain, sprockets, load bearing shafts, connecting end shafts, wheels and guide rails, hanging garages, electric motor, sets of 8" & 6"reduction gears, connecting shafts, couplings providing drive to 4 top sprockets, hydraulic jack with plate to lift hanging garage floor to ground level, Turn Table to facilitate parking and de- parking of cars.

Electrical and electronic control panel (Software system) for automation of following operation is provided.

1) Bring the desired hanging garage to bottom

2) Raise the floor of hanging garage to ground level 3) Lower the floor below ground level after parking/de-parking

4) Positioning of turn table to park or de-park the car

5) To rotate hanging garages to desired position

The floor of hanging garage and lifting plate on the hydraulic jack are so designed to facilitate locking of at least one pair of wheels (Front or Rear) to prevent any back ward or forward movement of the car parked in hanging garage.

Whenever any car is to be parked, the car is brought on the turn table and then the turn table is turned 90 degrees to enable the car to enter the hanging garage which is brought to bottom by chain and sprocket rotation. Hydraulic jack is activated to lift the floor of hanging garage to ground level. Car is parked in the garage and garage floor is lowered by again activating the hydraulic jack. All operations are carried out in reverse cycle to get the car out of the hanging garage.

Thus the hanging car park provides facility to park more cars in a 6 Mtr x 6 Mtr area, eliminates the hassles of movements of other parked cars. This device is very economical.

Claims

I CLAIM
