Abstract
An improved device for immobilizing or impounding any vehicle includes a pair of jaws that can be brought together on either side of a wheel to capture that wheel. A chock of width equal to the wheel rests against the ground and prevents movement of the captured wheel. The device is preferably made of hardened steel and is assembled in such a way as to make non-destructive disassembly impossible. The design and construction of the device make it impossible to twist or otherwise misalign the jaws or the chock of the device, except by use of extreme and excessive force.
Claims9
A device for immobilizing a wheel, comprising:
- a ratchet bar;
- an active bar connected to and lying in approximately the same plane as said ratchet bar, said active bar including an active jaw and an active leg, said active jaw and active leg extending on opposite sides of said ratchet bar;
- a passive bar lying in approximately the same plane as said ratchet bar, said passive bar including a passive jaw extending on the same side of said ratchet bar as said active jaw and offset from said active jaw to prevent interference of said jaws, said passive bar further including a passive leg extending on the same side of said ratchet bar as said active leg;
- and
- locking means for securing said ratchet bar to said passive bar, said locking means permitting said ratchet bar and said active bar to slidably move toward said passive bar, causing said active jaw and said passive jaw to engage a wheel between said jaws, thereby permitting said ratchet bar to rest against the road surface of said wheel and causing said active leg, said passive leg, and said ratchet bar to form a chock limiting rotation of said wheel.

A device for immobilizing a wheel, comprising:
- a ratchet bar having a plurality of teeth, said ratchet bar further including a handle formed from an extension of said ratchet bar;
- an active bar connected to and lying in approximately the same plane as said ratchet bar, said active bar including an active jaw and an active leg, said active jaw and active leg extending on opposite sides of said ratchet bar;
- a passive bar lying in approximately the same plane as said ratchet bar, said passive bar including a passive jaw extending on the same side of said ratchet bar as said active jaw and offset from said active jaw to prevent interference of said jaws, said passive bar further including a passive leg extending on the same side of said ratchet bar as said active leg;
- and
- locking means for securing said ratchet bar to said passive bar, said locking means including a channel for passage of said teeth and a detent for engaging said teeth, said locking means permitting said ratchet bar and said active bar to slidably move toward said passive bar, causing said active jaw and said passive jaw to engage a wheel between said jaws, thereby permitting said ratchet bar to rest against the road surface of said wheel and causing said active leg, said passive leg, and said ratchet bar to form a chock limiting rotation of said wheel.

A device for immobilizing a wheel, comprising:
- a ratchet bar;
- first means forming an active bar rigidly connected to and lying in approximately the same plane as said ratchet bar, said active bar including first jaw portion and first leg portion, said first jaw portion and said first leg portion extending on opposite sides of said ratchet bar;
- second means forming a passive bar lying in approximately the same plane as said ratchet bar, said passive bar including second jaw portion extending on the same side of said ratchet bar as said first jaw portion and offset from said first jaw portion to prevent interference of said jaw portions, said passive bar further including a second leg portion extending on the same side of said ratchet bar as said first leg portion;
- and
- locking means for securing said ratchet bar to said passive bar, said locking means for securing said ratchet bar to said passive active bar to slidably move toward said passive bar, causing said active bar and said passive bar to engage a wheel between said first and said second jaw portions, thereby permitting said ratchet bar to rest against the road surface of said wheel and causing said first and said second leg portions and said ratchet bar to form a chock limiting rotation of said wheel.
