Overhead drilling apparatus
A drill apparatus including an inner tube, an outer tube slidably received within the outer tube, and a pole extension mechanism. The pole extension mechanism comprises a pole advance gear having pole advance gear teeth, and a drive gear having drive gear teeth, the drive gear being coaxial with and fixedly attached to the pole advance gear so that the two gears rotate together. The pole advance gear teeth are received in aligned spaced apart apertures in the outer tube. The pole extension mechanism further includes a lever arm having an end pivotally mounted on the support collar at a lever arm pivot point coaxial with the drive gear and the pole advance gear. The pole extension mechanism further includes a stop pawl pivotally mounted on the support collar for rotation between where the stop pawl engages the drive gear and prevents downward movement of the pole inner tube relative to the pole outer tube, and where the stop pawl does not engage the drive gear, and a drive pawl piece pivotally mounted on the lever arm near the lever arm end.

Curtain airbag device mounting structure and curtain airbag deployment method
A curtain airbag device mounting structure includes: a first pillar forming a part of a front pillar and extends substantially along a vehicle height direction; a second pillar forming another part of the front pillar, the second pillar being disposed on a rear side of a vehicle relative to the first pillar at a predetermined distance from the first pillar and extending substantially along the vehicle height direction; a transparent member bridged between the first pillar and the second pillar; and a curtain airbag device including a curtain airbag stored along a roof side rail and the second pillar, the curtain airbag being configured to inflate and deploy in a curtain-like fashion over a side portion of a cabin of the vehicle in case of a collision of the vehicle.

TRANSPORTATION AND ELEVATION ASSIST DEVICE AND METHOD FOR TOOL HAVING STUCK BIT
A tool for removing a stuck bit of a drilling device from the drilling medium in which it was being drilled is provided. The system generally comprises a frame, a hydraulic lift operably connected to the frame, and a lifting platform. Operating the hydraulic lifting device may cause a strut to move in a linear direction, which may cause the carriage to move in a linear direction. By moving the strut in linear direction such that the carriage extends beyond the length of the drilling device, the carriage may contact the drilling medium, which may cause a lifting force to be applied to the drilling device. A user may then use the carriage to move the drilling device to a new location.

OVERHEAD DRILLING APPARATUS
A drill apparatus including an inner tube, an outer tube slidably received within the outer tube, and a pole extension mechanism. The pole extension mechanism comprises a pole advance gear having pole advance gear teeth, and a drive gear having drive gear teeth, the drive gear being coaxial with and fixedly attached to the pole advance gear so that the two gears rotate together. The pole advance gear teeth are received in aligned spaced apart apertures in the outer tube. The pole extension mechanism further includes a lever arm having an end pivotally mounted on the support collar at a lever arm pivot point coaxial with the drive gear and the pole advance gear. The pole extension mechanism further includes a stop pawl pivotally mounted on the support collar for rotation between where the stop pawl engages the drive gear and prevents downward movement of the pole inner tube relative to the pole outer tube, and where the stop pawl does not engage the drive gear, and a drive pawl piece pivotally mounted on the lever arm near the lever arm end.

METHOD FOR ENGAGING A DRILL TRIGGER ON A DRILL AS IT IS ADVANCED TOWARD THE CEILING WITH A DRILL APPARATUS
A method for engaging a drill trigger on the drill as it is advanced toward the ceiling with the drill apparatus. The drill includes the drill trigger positioned near the upper tube by a drill support for holding the drill, the drill support being mounted on the upper tube. The method includes the steps of: providing a strand looping over the drill trigger, so that the strand extends toward the lower tube. The strand is attached to the lower tube to secure the strand against movement towards the drill, so that the drill trigger is depressed by the strand when then the upper tube moves relative to the outer tube and towards the ceiling.
