Abstract

A train platform comprises a plurality of individual sliding platforms 2 which bridge the gap between a train and the main body of the platform 5. The platform 5 is provided with magnets 3 and 6 of opposing polarity, a wire or other electric current carrying means 4, and a cover plate (1, figure 1). The platforms 5 are individually movable backwards and forwards by applying an electric current through the current carrier 4 in forward and reverse directions. A resistor is used to adjust the current to obtain the desired force on the platforms 5.

Description

Sliding Platform Tecbnical Field This invention relates to a sliding platform.
Background Platform is well known waiting area for commuter in the underground or train station.
The conventional platforms are rigid and non-movable and are built with cement or concrete. Once completed it tends to leave a variable size gap between a platform edge and a stationary vehicle when in operation.
The gaps are vary in size dependent on a platform curve in relation to a stationary vehicle. Sometimes, it can be quite dangerous for commuters such as mother with pushchair, children and blinds to alight or aboard a stationary vehicle if the gap between the train door and platform edge is too large. Evidence shown that it is necessary to leave a reasonable gap between the vehicle door thresholds and the platform edge to provide sufficient clearance for vehicles to negotiate bend and curve, thus creating danger or inconvenience to commuters who have to cross this gap. Platform is expensive to build and is rigid once completed. It is not cost effective to alter a platform profile to suit different vehicle size or to bridge the gap as circumstances required Essential According to present invention there is provided add -on sliding platform Tecbnical or arrangement for bridging the gap between a stationary vehicle and a Feature rigid platform edge.
A sliding platform or arrangement comprising a cover-plate used to protect individual movable mini platforms and also to enable them to extend and withdraw within its confined distance and space as well as to prevent commuters to come into contact with the movable mini platforms, an individual mini platform forms a large platform required for bridging the gap between a stationary vehicle and a rigid platform edge, two permanent magnets bearing (S) south and (N) north poles or similar device are placed opposite to each others to provide magnetic field and a wire or a current carrier carries applied current when needed is placed in between two magnets or in similiar manner to create a catapult force .This catapult force is used to extend or withdraw each individual mini platform to form a large platform required for bridging the gap between a stationary vehicle and a rigid platform edge or return to withdrawn position as its current is reversed.
Example A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1: shows the end view of a sliding platform fitted to a rigid platform in withdrawn position.
Figure 2: shows the end view of a sliding platform fitted to a rigid platform in extended position.
Figure 3: shows in perspective, the view of a sliding platform formed by many individuals movable mini platforms fitted to a rigid platform in withdrawn position.
Figure 4: shows in perspective, the view of a sliding platform formed by many individuals movable mini platforms fitted to a rigid platform in extended position.
Figure 5: shows in perspective, the view of a sliding platform in extended position to bridge different size gaps between a rigid platform edge and a stationary vehicle.
Figure 6: shows in perspective, the view of the sliding platform formed by many individuals movable mini platforms in withdrawn position together with cover-plate.
Figure 7: shows a sectional view taken on line V - V in Fig. 3 to show the field from the two magnets placed in opposite manner with no induced current between them.
Figure 8: shows a sectional view taken on line V - V in Fig. 4 to show the combined field ( Catapult field ) created by induced current to a wire or a current carrier between two magnets; thus a force is produced on the wire by the current. Such force is used to extend and withdraw a sliding platform for bridging the different gap between a rigid platform edge and a stationary vehicle at the platform.
Referring to the drawing in Fig.l the sliding platform (2) comprises a fixed cover-plate (1) is placed on top of the sliding platform (2) to provide protection from commuters as well as room for sliding motion.
The cover-plate (1) can be bolted on to the existing rigid platform surface (5) or by similar means in Fig.6. The rigid platform (5) is being embraced by many individuals sliding platforms (2) which slide on a smooth surface of the rigid platform (5) or similar device in Fig3. Two permanent magnets (3) & (6) in Fig.l or similar means bearing (S) South and (N) North poles are placed to the vertical edge of the rigid platform in opposite position to provide magnet force. A wire or a current carrier (4) or similar device is placed in between these two magnets (3) & (6) in Fig.7 to create catapult force (7) in Fig.8 when current is induced. The catapult force (7) in Fig.8 created by an induced current extends the sliding platform (2) to take up the clearance (9) between the rigid platform edge (5) and a stationary vehicle (8) in Fig.5. By reversing an induced current, hence reverse the catapult force thus withdraw the sliding platform in withdrawn position in Fig.6. A resistor or similar device is used to adjust the current to obtain desirable catapult force in operation.

Claims (6)

  1. Claims 1. A sliding platform is formed by many individuals movable mini sliding platforms.
  2. 2. A sliding platform as claimed in Claim 1 wherein guide means are provided such as cover-plate and smooth sliding surface to control the sliding movement of many individuals' mini platform bodies attached to a rigid platform edge.
  3. 3. A sliding platform as claimed in Claim 1 and Claim 2 wherein the sliding motion or movement is provided through catapult force by inducing current between the field created by two opposing magnets bearing (S) South and (N) north poles.
  4. 4. A sliding platform as claimed in Claim 1 to Claim 3 wherein different catapult force ( Sliding force ) is controlled by varying the current being induced or similar device may also be used.
  5. 5. A sliding platform as claimed in Claim 1 to Claim 4 wherein the forward and backward movement of a sliding platform is controlled by reversing the applied current or via verso
  6. 6. A sliding platform substantially as described herein with reference to Figures 1-8 of the accompanying drawing.
