CHENG - Web page: https://patentgrep.com/patent/US20140151161A1 ## CPC - B60T 3/00: Portable devices for preventing unwanted movement of vehicles, e.g. chocks - B60T: VEHICLE BRAKE CONTROL SYSTEMS OR PARTS THEREOF; BRAKE CONTROL SYSTEMS OR PARTS THEREOF, IN GENERAL (electrodynamic brake systems for vehicle, in general B60L; brakes per se, i.e. devices where braking effect occurs, including ultimate brake actuators, F16D); ARRANGEMENT OF BRAKING ELEMENTS ON VEHICLES IN GENERAL; PORTABLE DEVICES FOR PREVENTING UNWANTED MOVEMENT OF VEHICLES; VEHICLE MODIFICATIONS TO FACILITATE COOLING OF BRAKES ## Abstract A car stop plate includes a stop having a penetrating hole for locking or being penetrated by other tool for retaining; a supporting sheet extending from a lower side to a predetermined distance; widths of the supporting sheet being reduced from an end near the stop to a front end; a length of the supporting sheet being based on a distance from lowest point of a wheel of a car to a foremost or rearmost of the car. In use, the stop resists against a front wheel of a car; the wheel of the car will press the supporting sheet so as to retain the supporting sheet motionlessly. When a driver desires to park a car, the car can be stopped quickly by resisting against the car stop plate in a specific position. ## Claims ### Claim 1 A car stop plate, comprising: a stop having a penetrating hole for locking or being penetrated by other tool for retaining the stop; a supporting sheet extending from a lower side to a predetermined distance; widths of the supporting sheet being reduced from an end near the stop to a front end; wherein in use, the stop resists against a front wheel of a car; the wheel of the car will press the supporting sheet so as to retain the supporting sheet motionlessly. ### Claim 2 (depends on 1) The car stop plate as claimed in claim 1, wherein a first action area is formed on an upper side of the supporting sheet and near the stop; and the first action area is formed with a plurality of holes; a second action area is formed with a plurality of notches; the second action area is extended from a front end of the first action area; and the second action area is formed with a plurality of notches; and a third action area is formed on a lower side of the supporting sheet which is opposite to the upper side of the supporting sheet; and the third action area is formed with a plurality of recesses. ### Claim 3 (depends on 2) The car stop plate as claimed in claim 2, wherein the first action area and the second action area serves to provide friction force to a car on the car stop plate and the holes of the first action area and the notches of the second action area serves to drain water; and the recess of third action area serves to generate friction force between the supporting sheet and ground so as to reduce displacement between the supporting sheet and ground. ### Claim 4 (depends on 1) The car stop plate as claimed in claim 1, wherein a length of the supporting sheet is approximately equal to a lowest point of a wheel to a front end of a car or to a rear end of a car. ### Claim 5 (depends on 1) The car stop plate as claimed in claim 1, wherein two sides of the front edge of the first action area exposes out and each expose front side is formed with a groove for receiving a respective engaging rod. ### Claim 6 (depends on 5) The car stop plate as claimed in claim 5, wherein each lateral side of each groove is formed with a penetrating hole; and each engaging rod has a protruded stem which is formed with an engaging hole; in assembly, a stud serves to pass through the penetrating holes of the groove and the engaging hole of the engaging rod so as to retain the engaging rod to the first action area so that the length of the whole supporting sheet is prolonged. ### Claim 7 A car stop plate, comprising: a stop having a penetrating hole for locking or being penetrated by other tool for retaining the stop; and a supporting sheet extending from a lower side to a predetermined distance and being formed with a front end; thicknesses of the supporting sheet are reduced from a end near the stop to the front edge; and an engaging sheet having a rear edge for engaging to the front edge of the supporting sheet; ### Claim 8 (depends on 7) The car stop plate as claimed in claim 7, wherein the front edge of the supporting sheet is formed with at least one groove; each lateral side of each groove is formed with a penetrating hole; a rear edge of the engaging sheet is formed with at least one protrusion which can insert into the groove of the supporting sheet; and the at least one protrusion having a hole, a stud is used to insert through the penetrating holes of at the lateral side of the groove of the supporting sheet and the hole of the protrusion to combine the engaging sheet to the supporting sheet. ### Claim 9 (depends on 7) The car stop plate as claimed in claim 7, wherein a fourth action area is formed on an upper surface of the supporting sheet; the fourth action area is formed with a plurality of through holes; and a fifth action area is formed on a bottom surface of the supporting sheet of the supporting sheet which is opposite to the upper surface of the supporting sheet; and the fifth action area has a plurality of recesses. ### Claim 10 (depends on 7) The car stop plate as claimed in claim 7, wherein a front edge of the engaging sheet is formed as a sixth action area which includes a plurality of recesses; two sides of the front edge of engaging sheet are formed with trenches; a back side of the engaging sheet is formed as a seventh action area which is formed with a plurality of recesses. ### Claim 11 (depends on 7) The car stop plate as claimed in claim 7, wherein the engaging sheet is formed as an integral block with an inclined front surface for contacting with a front side of a car wheel; and a rear side of the engaging sheet is formed with a protrusion to be engaged to the supporting sheet. ### Claim 12 (depends on 8) The car stop plate as claimed in claim 8, wherein the supporting sheet is formed with hollow space for reducing the weight of the whole car stop plate. ### Claim 13 (depends on 7) The car stop plate as claimed in claim 7, wherein a length of the supporting sheet being based on a distance from lowest point of a wheel of a car to a foremost or rearmost of the car;
