  "abstract": "A locking device for car wheels is disclosed to prevent unauthorized removal of the wheels. The device includes a locking unit that allows covering of special bolt heads by covering wings. The locking module can be further covered with a covering plate. The system provides multiple layers of protection to the wheels and considerably lengthens the time required to remove the wheel without proper keys.",
  "claims": [
    "1. A wheel locking device comprising: a center part having a front side and a back side; a multitude of nut head cases extending radially from the center part, wherein at least two of the nut head cases are covered and adapted to cover lug nut heads, and at least two cases have a through hole perpendicular to the front side of the center part for a bolt head to fit in the case; a locking unit extending through the center part, and having a key hole on the front side of the center part and a lock stud on the back side of the center part; a lock plate on the back side of the center part within a guiding rim and being attached to the lock stud; the guiding rim having at least two slots through which two covering wings extend toward the nut head cases having the through holes; the covering wings being attached to the opposite ends of the locking plate with pins; wherein: the locking stud turns within the guiding rim when a key is turned in the key hole; turning of the locking stud moves the pins and the pins move the covering wings to cover the through holes when the device is in locked position and expose the holes when the device is in unlocked position, whereby an access is provided to the bolt heads.",
    "2. The device of claim 1, wherein the center part has a cover retaining notch in the front side and a covering plate is attached to the notch to cover the locking unit.",
    "3. The device of claim 1, wherein the center part is circular.",
    "4. The device of claim 1, wherein the device has two cases for bolt heads and three for lug nut heads.",
    "5. The device of claim 1 claims, wherein the lock stud extends through the lock plate.",
    "6. The device of claim 1 wherein the device is made of steel or aluminum.",
    "7. A kit for locking a wheel, said kit comprising a locking device of claim 1, a multitude of lug nuts, at least two bolts, a key fitting to the key hole and wrenches to open the lug nuts and the bolts.",
    "8. A car wheel kit comprising car wheels, locking devices of claim 1, a multitude of lug nuts, at least two bolts, a key fitting to the key hole and wrenches to open the lug nuts and the bolts."

  "description_excerpt": "This application claims priority of U.S. provisional application No. 62/252,008 and of Swedish application number SE 1551440-9, both of which were filed on Nov. 6, 2015, and the content of both of which is incorporated herein by reference.\n\nThis invention relates to methods and devices to prevent unauthorized removal of car wheels. More specifically this invention relates to a comprehensive locking system for car wheels.\n\nUnauthorized removal of car parts, specifically alloy wheels is a frequently occurring problem all over the world. Due to their high value custom wheels and tire rims are examples of items frequently stolen. Accordingly, there is a great need for device to protect wheels from unauthorized removal.\n\nThere have been attempts to provide such protection. For example U.S. Pat. No. 8,739,585 and U.S. Pat. No. 8,943,865 disclose antitheft devices for car wheels. However, none of the devices known in the art provide truly reliable wheel locks to prevent theft effectively. All of the known devices can be removed relatively easily by an experienced thief. Some car brands do use five lug nuts instead of four on each wheel, which could increase the time a thief has to spend to remove the wheel. Some car brands use special lug nuts that require specific keys to open them. The main idea in these solutions is that increasing the time needed to remove the wheel may to some extent prevent a theft. However, removing the wheels is still relatively easy and the problem of unauthorized removal of car wheels is not yet solved.",
