MECHANICAL PORTER

(A drag & push luggage trolley can do 3 works - LIFT, MOVE & PLACE the luggage)

 INTRODUCTION:

 Here is to a  new device that lets you   do LIFT, MOVE  and  PLACE your  own  luggage  yourself  with ease  without  depending porters/others   while you are at  the Air Port/ Railway  and Bus Stations. Of course, the trolleys now available at the air Port/ Railway Stations can help us to carry our luggage. But this trolleys will not help us to  lift the luggage from the conveyor belt in Air Ports/from Trains or to place it in vehicles. Now this Mechanical porter comes to your rescue  and this single machine can do all this  three works (LIFT, MOVE & PLACE)  that  a manual porter  can do - so it is called Mechanical Porter.

          Actually Mechanical porter replaces the need of lifting/placing  the luggage because we can able to raise/lower the luggage platform of the trolley  to the level/height  of the luggage ( where as the plat form  in the  conventional  trolley  is fixed).  Here all we have to do now is just DRAG or PUSH  the luggage. So it is otherwise called DRAG & PUSH trolley. Even  your  small child can able to  lift you  to a height of  4 feet  by just pedaling by hand or foot.

          This machine is cost effective.  It may  be noted here  that some  kind of  very costly lifting  machines (with motorized hydraulic  jockeys) are usage at industries. But this mechanical porter runs on  simple mechanism  without motors, batteries  or costly hydraulic  jockeys. Actually the commuters  uses the trolleys occasionally for  small movement of 5 to  10 minutes and thus there is no need of  motorizing  this machine. More over motorizing this machine make pollute the busy Air port/Railway stations besides makes it costlier and subject to periodical maintenance as well.  Thus  the  pedaling system in this  mechanical porter makes this machine  not only cost effective but also maintenance free and power free  and thus environmental free also. The applications of this machine is  not only  restricted with Air Port and Railway stations but also has wide range of usage at  homes, Departmental stores and libraries  as well.

 AIM OR OBJECT OF INVENTION:

The rationale behind the construction of the model is the absolute necessity for avoiding the physical hard work in LIFTING and PLACING HEAVY LUGGAGES at the Air Port Railway Stations by the commuters( especially women  &old age  and Physically challenged people) from Train/Conveyor belt to trolley and trolley to car or to other vehicle. 

 THE PRESENT SYSYEM:

At the Air port or Railway Station or Bus stations, at present the trolleys are available, giving the helping hand to the passengers to carry the luggage from one place to another. Even then, the passengers find it very difficult to lift their heavy luggage from the conveyor belt (at Air ports) or from train or other vehicles to the trolley and from trolley to vehicles (outside the Airport/Railway Stations/Bus Stations). For this work, they have to be dependent on porters or some helping minded people.  Lifting the luggage IN/OUT of trolley is more troublesome for the lady passengers, senior citizens and physically challenged people, especially when they travel alone. Likewise there is a risk of allowing strangers inside the house as the  house wives at homes depending some body  to lift and carry  gas cylinders(30Kg) and water bottle(20 lt) and other heavy domestic things.

 SOURCE OF IDEA:

     I am Masha Nazeem, a girl student who designed this device.  I used to go by air often to attend various science expos and seminars. At times, I had to travel alone.  While entering into or coming out of the Air port, I felt it very difficult to lift the luggage at various points.  The trolley available at Airports helps the passengers only to move the heavy luggage from one place to another. But lifting the same at various points at the Air Ports is something difficult for the passengers of above mentioned category. This problem exists not only in Indian Air Ports but also in all over the world including Dubai and Tokyo - the Air Ports I have visited so far. This led me to design a Lift  Carry & Place Trolley, otherwise called MECHANICAL PORTER.

THE  BASIC FACTORS IN DESIGNING THE MECHANICAL PORTER

While designing the Mechanical Porter the following concepts are taken in to account.

  Economically viable.  The present model of  the trolley that is used in  the Air port is very simple,  and maintenance free.  So the new solution should  be  even more simple, less maintenance  and  economical  at the same time with more  added facility.

  Commercially viable.  The model should be a commercially viable alternate to the existing model available in the market in terms of price.

 Customer friendly: The targeted users  of  this  product are weaker sections of  the society. � such as old age people,  physically challenged people, ladies and boys & girls. So the handling of the machine should be very easy.  

 Environmental  friendly: The places where this machine  actually put in use are thickly populated  busy areas (Air port/Railway Station).  So this machine should be  environmental friendly.  So the usage of motors or batteries should be avoided.

 Exploiting users psychology: The people  who use this machines are only occasional users. The pedaling work that they have to do is neither  an additional job nor a full time job. As the passengers  remain idle in their seat  in a same position for a long time during their travel, they will feel happy to  do this  one minute   easy manual  work  as a warming up exercise.

Universal application:  A product should be successful if it has a domestic usage. So the design should be of universal application in domestic, libraries, departmental stores and Hospitals and  now even the house wives  can carry  carrying gas, water bottles  to kitchens  without allowing strangers inside the houses.

HOW DOES IT HELPS IN  LIFTING THE  OBJECTS ?

  With the help of this trolley, we can easily drag the luggage from the conveyor belt or from train coaches towards the trolley by moving the platform of the trolley to the desired height. Here we need not lift the luggage. All we have to do is just drag the luggage. Again by rotating the pedal we can move the platform little bit down and adjust the level of the already placed suitcase/box again to the level of the conveyor belt or train.  Now, drag and load the second luggage and so on. Like wise, we can place  the luggage in the car by pushing the luggage one by one by adjusting the level of the platform to the necessary height. Thus, by doing the simple things, Drag & Push, we can easily move heavy luggage from one place to another comfortably without straining much  and without expecting help from others in lifting the same

ADVANTAGES OF MECHANICAL PORTER

1     MECHANICAL PORTER is a very useful device and will be very handy to use in Airports, Railway Stations, Bus Terminals, Hospitals etc., to lift and move heavy luggage and baggage.(Refer photograph)

2      MECHANICAL PORTER has various other domestic applications also. Now  the home care takers can lift, carry and place the heavy objects such as gas cylinders(30Kg), mineral water(20 liters cane) to the height up to 4 feet very comfortably without the help of others. Thus handling of heavy  material  at homes becomes easier.(Refer Photograph)

3     Also this MECHANICAL PORTER has wide range of utilities in commercial departmental stores, and central libraries in the educational institutions etc.

4     At present, no such multi purpose devices, for lifting, carrying and  placing the objects simultaneously, in the above mentioned places, are available anywhere in the world.

5     This machine is cost effective. In large scale production the price may lesser than the conventional trolleys.

6     Actually the commuters  uses the trolleys occasionally for  small  movement of 5 to  10 minutes and thus there is no need of  motorizing  this machine. More over motorizing this machine make pollute the Air port/railway stations besides makes it costlier and subject to periodical maintenance as well.  Thus  the  pedaling system in this  mechanical porter makes this machine  not only cost effective but also maintenance free and power free  and thus environmental free also Mechanical porter is Environmental friendly.
