ALPHA URBAN FLOOD RELIEF RAFT
The rafts used for current flood relief are mostly inflatable rafts and are susceptible to puncture in flood like condition. Transporting such boats can be difficult in crowded city conditions.
This flood relief raft is an assembly of hollow panels and securing parts which enable assembling a raft on site while packing it in box shape when it is not required and to be transported or stored. The panels are made of metal or plastics that have following properties light weight and tensile strength i.e. Al and steel.
The cross members are made of metal or plastics that have significant tensile strength i.e. steel.
The raft is an assembling type raft for use for flood relief or similar applications. The essential features of the raft are -
a. It is made up of seven box shaped panels numbered 1 to 7 from left to
right.
b. The panels 1,7 are 2500 mm Long x 240 mm wide and 240 mm high.
(Item 2 in drawing A)
c. The panels 2,6 are 2500 mm Long x 240 mm wide and 120 mm high
(Item 1 in drawing A).
d. The panels 3,4,5 are 2500 mm long x 240 mm wide x 60 mm high.
(Item 3 in drawing A)
e. The panels are hollow, made of metal and optionally may contain
buoyant foam material inside.
f. The length of the panel is taken as 'along' and the perpendicular
direction is taken as 'across'.
g. The device has six pipes running across the panels above and below
the panels referred here as 'cross members'.

h. There are three cross members running across the panels above it (Item 5 in drawing A) and three cross members running below the panels (Item 4 in drawing A) to secure it in raft shape.
i. There are stoppers fixed to side of each panel that restrict the position of adjacent panel to its assigned position in 'along' direction.
j. The lower cross members have lugs fitted to it.
k. The panels are placed on and supported by the lower cross members. ,
1. The lower cross members has lugs fitted to it, between which, the panels sit snugly and which restrict the panels from 'across' movement.
m. The upper cross member passes through the lugs welded on lower cross member while holding the panel between them.
n. The outermost panels 1 and 7 have pipe welded through them in 'across direction. These pipes serve the purpose of keeping the panel watertight even when allowing the cross member to pass through it.
o. The lower cross member passes through these 'cross' pipes of panel 1,2,6 and 7.
p. The cross member has a 50 mm diameter washer and an oval handle on one end. It has threads on the end. A butterfly nut with a 50 mm washer plate is used to secure the other end on these threads after the upper cross member passes over/under/tnrough all the panels.
q. .A bayonet type socket is provided on top of 2 and 6 panel. A single vertical pipe (Item 6 in Drawing A) with two pins at the bottom are used to secure the rail to this socket.
r. There is a lug in 'across' direction to secure a portable two step ladder on panel 2 and 6. There is a distance of 40 cm in 'along' direction between the rail socket and the lug for the ladder to facilitate person to hold rail and place leg on ladder to climb on to the raft from the water.

Statement of Claims
Claim 1: A design of an assembling type raft comprising of multiple panels, 'cross' members that can be assembled as a raft for use on water or packed in box shape for 'transport' and each part is lightweight and has a specific position in the assembled raft and held in this place by the designed ■ appendages.
