Abstract

An improved Mob Control Vehicle (MCV) may be necessary to handle riots and mobs in the streets and grounds at urban and non-urban areas. One of the important requirements of this mob control activity is barricading the entire road or ground in such a way that mob cannot harm the vehicle or ground security personnel directly. Accordingly the present invention provides a Vehicle mounted Sliding Type Retractable mobile Protective Shield, which is integrated with MCV. In general the shield is in fivefold retracted condition on rooftop of the vehicle and can be transported at sites without dismantling. During mob control activities the entire shield is brought down on the ground in vertical position ahead of the vehicle through hydraulically actuated cylinders. The side shield frames are expanded as per requirement or road or ground width, such that it can barricade the entire road or ground to protect the vehicle as well as security personnel from aggressive mob. Once the mob control activities are over, the entire shield is folded and retracted on the roof for transportation.

First claim

What is claimed is:

1. A vehicle mounted sliding type retractable mobile protective shield comprising: a central shield frame, two hardened metal fire resistant large side shield frames, two hardened metal fire resistant small side shield frames, two banana boom links, two bottom hydraulic cylinder, two top hydraulic cylinders, two sliding hydraulic cylinder, two linear motion guide rails, two bearing guided channels, four linear motion bush guides, and two lift platforms on their respective lift cylinders on both sides of said central shield frame to provide a fivefold protective opaque barricade.

2. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein the entire structure is integrated with a base vehicle for necessary on road movement during deployment as well as transportation.

3. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein said banana boom links, bottom hydraulic cylinders and top hydraulic cylinders hold the hardened and fire resistant shields ahead of the vehicle in a vertical position during deployment to protect the vehicle and security personnel.

4. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein said banana boom links, bottom hydraulic cylinders and top hydraulic cylinders retract the entire shield frames onto a rooftop of the vehicle in a horizontal and compact position during transportation.

5. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein said banana boom links, bottom hydraulic cylinders and top hydraulic cylinders provide controlled gradual up and down movement of said shield frames during deployment for instant release of security personnel in front of the shield.

6. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein the shield frames rest firmly on a rooftop structure in a complete compact condition and a mechanical lock system hold said shield frames positively to arrest any kind of vibration during transportation such that all shield frames are retracted above the rooftop.

7. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein during deployment the sliding hydraulic cylinders expand and collapse, widthwise, the large side shield frames on both sides in respect to the central shield frame through sliding motion, via said linear motion guide rails and bearing guided channels.

8. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein during deployment the small side shield frames can be expanded and collapsed widthwise on both sides in respect to the large side shield frames through sliding motion via said linear motion bush guides.

9. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein, the combination of sliding motion of all side shield frames can achieve any intermediate position between a maximum and minimum width of the entire shield, leading to barricading any road or ground width in that range.

10. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein narrow viewing ports on the opaque plates of shield frames so that only ground security personnel can see the situation of mob on other side but mob cannot see the position of security personnel.

11. The vehicle mounted sliding type retractable mobile protective shield of claim 1 , wherein on both sides of central shield frame there are two lift cylinders, on which two separate lift platforms are mounted for up and down movement of the security personnel.
