Detailed description of the invention:

According to the invention as shown in fig 1, a wicket assembly for the game of cricket consists of a base assembly and stump or stumps.

) MPB/ENK/PATENT/CON/2008 1422/DEL/2008

Base assembly of the wicket assembly for the game of cricket consists at least one or more than one unidirectional quadrant (1). All quadrants are engaged to each other unidirectionally and formed a single base assembly (21) with the help of interlocking means as shown in fig.6.

A tapered conical cavity (2) is provided around the center of each quadrant (1) for holding a stump (3) vertical : straight. A groove (17) as shown in fig 2 is provided at the top end of the tapered conical cavity (2) of the quadrant (1) to provide a locking means between quadrant (1) and stump (2). The quadrant (1) is hollow in shape having a plurality of supporting ribs (20) provided within the hollow cavity (2) to give a uniform even support and strength to the quadrant (1) and simultaneously providing the strength to the tapered conical cavity (2) of the quadrant (1).

According to the present invention as shown in fig 3 and 4, the stump (3) is a cylindrical hollow pipe. The stump (3) is made of hard plastic or any other polymer.

’ MPB/ENK/PATENT/CON/2008 1422/DEL/2008

The lower and upper end of the stump. (3) are detachable.

Upper end of the stump (3) is a round shaped hollow cylindrical cap (10) with a notch (15) provided at the upper end of the cap (10). A plurality of the vertical protrusions (13) is provided at the outer surface of the cylindrical lower end (14) of the cap (10).

Middle part of the stump (3) is a cylindrical hollow pipe (4), attached with cap (10) and V shaped conical artifact (8) respectively at the upper end (11) and the lower end (9) of the hollow pipe (4). ‘The shape and size of the v shaped artifact (8) of the stump (3) is very specific and inconformity with the tapered conical cavity (2) of the quadrant (1). ‘A plurality of vertical shaped protrusions (12) are provided at the outer surface end of the cylindrical hollow cap (6) provided at the top end of the v shaped artifact (8) as a means for locking between stump(3) and V-shaped artifact (8). A protrusion (5) 1s provided between the cylindrical cap (6) and V shaped conical configuration (9) of the artifact (8) as a means for locking arrangement

’

MPB/ENK/PATENT/CON/2008 1422/DEL/2008 between the tapered conical cavity (2) of the quadrant (1) and stump (1).

The lower end (7) of the V shaped conical artifact (8) is straight tubular structure with a rounded tip to provide more strength and support to the stump when locked.

According to the present invention two locking arrangements are provided. 1. Locking arrangement between stump and quadrant and 2. interlocking arrangement between the quadrants.

The locking arrangement between stump and quadrant is a press fitted type locking arrangement.

As shown in fig 1 and 4, the locking arrangement consists a plurality of vertical shaped protrusions (12) provided at the outer surface end of the cylindrical hollow cap (6) provided at the top end of the V shaped artifact (8) and a protrusion (5) provided between the cylindrical cap (6) and

V shaped conical configuration (9) to enable the stumps to be locked by means of V shaped artifact (8). )

) MPB/ENK/PATENT/CON/2008 1422/DEL/2008

According to fig (1), The V shaped conical artifact (8) of the stump is put inside the cavity (2) of the corresponding quadrant (1) and an external force is applied to the stump (3) from the top making the sald stump (3) to get locked inside the conical cavity (2). The stump (3) when locked, the stump (3) with the V shaped conical artifact (8) and the quadrant (1) is a one piece configuration detachable by © means of an external force.

As shown in fig (1) the bottom end of the V shaped artifact (7) protrudes the V shaped conical cavity (2) of the quadrant (1) to enable the artifact (7) to be locked in the tapered V shaped cavity (2) on applying an external force, wherein the bottom end of the cavity (2) is tapered having the centrifugal force applied from different side by means of spikes provided evenly.

As shown in fig (6), the quadrants are connected unidirectionally to each other by interlocking means. The interlocking means comprises at its one edge a protrusion (18) and at the other corresponding edge (19) of the other corresponding quadrant cavity (2) inconformity with the protrusion (18) to rigidly engage the said two quadrants

Prd bn r ) MPB/ENK/PATENT/CON/2008 1422/DEL/2008 together to make it a rigid one piece. The quadrant thus : forms a single piece that can be separated if a force or movement is carried out in the opposite direction.

While particular embodiments of the present invention have been illustrated and described, it would be obvious to : - those skilled in art that various other changes and modifications can be made without departing from the sprit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are with in the scope of this invention.
