The present invention, the locking device for a helmet 110 is comprised of a plurality of components. Such components in their broadest context include a flat bar and a padlock. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
Specifically, the present invention includes a T-bar shaped 114, as seen in FIG. 1. The T-bar has a generally rigid first flat bar 116 and a second flat bar 118. The first flat bar and the second flat bar each have a generally rectangular shape. The second flat bar is fixedly attached to the first flat bar with a Weld. The first bar, as shown in FIG. 3, has a length of about 6.5 centimeters and a width of about 2.5 centimeters. The second flat bar has a length of about 9.5 centimeters with a width equal to the width of the first flat bar.
The length of the second flat bar is about one third greater than the length of the first flat bar. The T-bar portion is formed of iron or steel for strength. The second bar 118 is centrally positioned on a top surface 122 of the first bar 116, and integral the first bar. The second bar extends outwardly from the first bar 116 in a plan perpendicular the first bar. The second bar has a free end 124 with an opening 126. The opening, as seen in FIG. 2, has a diameter of about 8 millimeters.
Lastly, as shown in FIG. 1, the free end 124, of the second bar, is positioned through a ventilation hole 132 of a helmet 134. The ventilation hole is centrally disposed through a shell 136 of the helmet. The opening 126 of the free end has a padlock 140 positioned therethrough, and around a bicycle frame 142, when the second bar 118 is passed through the ventilation hole of the helmet. Whereby, the helmet 134 is secured to the bicycle frame when the T-bar portion 114, is positioned through the hole the helmet, lockingly secures the helmet to the bicycle frame.
Furthermore, an alternative embodiment 10 is provided. The alternative embodiment includes a pair of L-shaped bar portions 14, as shown in FIG. 4. Each bar portion has a generally rigid first flat bar 16 with an elongated second flat bar 18 that is fixedly attached. Both L-shaped bar portions are formed of iron or steel. Each first bar has a length of about 1.5 centimeters and a width of about 2.5 centimeters. Each flat bar has a first bend 20 and a second bend 22, as shown in FIG. 5. The first bend of each second bar is angled inwardly about 60 degrees, as seen in FIG. 4.
The second bend of each second bar is angled outwardly about 60 degrees. Each bar is preformed with the first and second bends for strength. Each second flat bar, of FIG. 5, has a length of about 15 centimeters with a width equal to the width of the first bar.
As seen in FIG. 4, each second bar 14 extends from a top surface 26 of the first bar 16 and is integral the first bar. Each second bar extends outward from the first bar in a plan perpendicular the first bar. Each second bar has a free end 30 that is near the second bend 22.

Each first opening receives a link 42 of a short link chain 44. The chain is formed of an identical metal used to form the bar portions. Using an identical metal allows the chain to be just as strong as the bar portions. The short link chain loosely couples together each first bar, as shown in FIG. 4. Each link, coupled to one of the first openings, is welded closed to ensure the links aren't easily pulled apart and away from the respective free end.
Lastly, each free end 30 of the second bar 18 is positionable through one of a plurality of ventilation holes 48 of a helmet 50. The ventilation holes are predisposed through a shell 52 of the helmet. The ventilation holes come standard within helmets, therefor there is no need to cut a hole for use by the device. Each second opening 32, of each free end of each second bar, has a padlock 54 positioned therethrough when each second bar has been passed through one of the ventilation holes of the helmet. Whereby, the helmet is secured to the bicycle frame 58, when the pair of L-shaped bar portions are positioned through a respective hole of the helmet. The L-shaped bar portions are lockingly secured around the bicycle frame with the helmet.
The present invention is a locking device for a helmet. The present invention is comprised of a T-bar shaped portion. With an increase popularity of cycling and the trend of an increasing number of cyclists wearying helmets, there has been created a need for a device to securely store the helmet to the bicycle.
