Abstract
A police-car vehicle restraint has a pair of lift hooks with lift arms (7) having rigid hooks (5) outwardly from flat spring sections (50) which are attached pivotally to front ends of a chassis of a police car (10) for being pivoted selectively or simultaneously intermediate proximate verticality and horizontality. Swivel pads (22) can be positioned on the rigid hooks.
Claims19
A police-car vehicle restraint comprising:
- a pair of two separately operable lift hooks attached pivotally to a front end of a chassis of a police car for being pivoted to proximate verticality for a non-use mode, to proximate horizontality for a use-preparation mode and towards verticality for a use mode selectively;
- the pair of two separately operable lift hooks including a first lift hook and a second lift hook;
- the first lift hook and the second lift hook each having a vertically pivotal spring attachment on a pivot end, a hook on a hook end and a lift arm intermediate proximate the pivot end and the hook end;
- the vertically pivotal spring attachment including a flat-spring section;
- a first chassis attachment attachable predeterminedly to proximate a front end of a first chassis beam of a chassis of the police car;
- a second chassis attachment attachable predeterminedly to proximate a front end of a second chassis beam of a chassis of the police car;
- the pivotal attachment on the first lift hook and the first chassis attachment having a predetermined first pivotal connection;
- the pivotal attachment on the second lift hook and the second chassis attachment having a predetermined second pivotal connection;
- the pivot end of the first lift hook having a pivot transmission that is geared to a first pivot motor;
- the pivot end of the second lift hook having a pivot transmission that is geared to a second pivot motor;
- a control panel that is attachable to an interior portion of the police car for convenient view and access by an operator in the police car;
- the control panel having a first controller for control communication with the first pivot motor and a second controller for control communication with the second pivot motor selectively or simultaneously;
- the first pivot motor and the second pivot motor each having lifting power that is transmittable intermediate the pivot transmission and the hook end of the first lift hook and the second lift hook for lifting a predetermined vehicle weight on the hook of the first lift hook and the second lift hook by pivoting of the first lift hook and pivoting of the second lift hook intermediate proximate horizontality and verticality selectively or simultaneously through the first controller and the second controller on the control panel;
- and
- a lift surface on the hook of the first lift hook and the hook of the second lift hook.

A police-car vehicle restraint comprising:
- a pair of two separately operable lift hooks attached pivotally to a front end of chassis beams of the police car for being pivoted intermediate proximate verticality and proximate horizontality selectively with separate predetermined pivot motors that are operable by separate controls which are in control-power communication with the pivot motors from the control panel that is conveniently visible and accessible to an operator in the police car;
- a first lift hook and a second lift hook each having a vertically pivotal spring attachment on a pivot end, a hook on a hook end and a lift arm intermediate proximate the pivot end and the hook end;
- the vertically pivotal spring attachment including a flat-spring section;
- and
- the pivot motors each having predetermined lifting power that is transmittable intermediate the pivot transmission and the hook ends of the lift hooks for lifting the target vehicle weight on the lift hooks by pivoting the lift hooks intermediate proximate horizontality and verticality selectively or simultaneously through a first controller and a second controller on the control panel.
