Abstract

The shaft is caused to rotate by the moving of a rack along the side of the handle. A pair of one-way clutches causes the shaft to move only in one direction.

Total Claims: 9
Claim 1
Independent Claim
331 words
A manually operated handle for panoramic cameras comprising: a handle body having a central opening, said handle body having a vertical axis; a rotatable central shaft held by said handle body, said central shaft having a central axis parallel with the vertical axis of said handle body, said central shaft having an upper portion affixable to a panoramic camera and said central shaft having a lower portion; gear means affixed to the lower portion of said central shaft, said gear means having an axis of rotation at said central axis of said central shaft; a first one-way clutch means contacting the lower portion of said central shaft, said first one-way clutch means being located between said gear means and the upper portion of said central shaft, said one-way clutch means permitting said gear means to turn in a first direction to turn the upper portion of said central shaft and to turn in a direction opposite to said first direction freely without turning the upper portion of said central shaft; rack means slidably held by said handle body, said rack means having teeth which mesh with said gear means and said rack means being mounted at a right angle with respect to the central axis of said central shaft; a second one-way clutch held by said handle body, said second one-way clutch contacting the upper portion of said central shaft and permitting it to turn only in a first direction, whereby when said rack means is moved in a first direction, said gear means turns said central shaft in a first direction and said second one-way clutch permits such turning, but when said rack means is moved in a direction opposite to said first direction, said first one-way clutch means permits the gear means to turn freely with respect to the upper portion of said central shaft and said second one-way clutch prevents any turning of the upper portion of said central shaft in a direction opposite to said first direction.

A manually operated handle for panoramic cameras comprising: a handle body having a central opening, said handle body having a vertical axis; a rotatable central shaft held by said handle body, said central shaft having a central axis parallel with the vertical axis of said handle body, said central shaft having an upper portion affixable to a panoramic camera and said central shaft having a lower portion; gear means affixed to the lower portion of said central shaft, said gear means having an axis of rotation at said central axis of said central shaft; a first one-way clutch means contacting the lower portion of said central shaft, said first one-way clutch means being located between said gear means and the upper portion of said central shaft, said one-way clutch means permitting said gear means to turn in a first direction to turn the upper portion of said central shaft and to turn in a direction opposite to said first direction freely without turning the upper portion of said central shaft; rack means slidably held by said handle body, said rack means having teeth which mesh with said gear means and said rack means being mounted at a right angle with respect to the central axis of said central shaft; a second one-way clutch held by said handle body, said second one-way clutch contacting the upper portion of said central shaft and permitting it to turn only in a first direction, whereby when said rack means is moved in a first direction, said gear means turns said central shaft in a first direction and said second one-way clutch permits such turning, but when said rack means is moved in a direction opposite to said first direction, said first one-way clutch means permits the gear means to turn freely with respect to the upper portion of said central shaft and said second one-way clutch prevents any turning of the upper portion of said central shaft in a direction opposite to said first direction.
Claim 3
Dependent Claim
38 words
The manually operated handle of claim 1 wherein said rack means further includes a trigger at one end thereof so that the central shaft may be turned by squeezing the trigger and moving it towards the handle body.
Claim 4
Dependent Claim
56 words
The manually operated handle of claim 1 further including a worm gear rotatably affixed to said rack means, said worm gear having a handle at one end thereof and nut means affixed to said handle body whereby when said worm gear is turned by its handle, said rack means moves with respect to said handle body.
Claim 5
Dependent Claim
55 words
The manually operated handle of claim 3 wherein said nut means is movable between a first position in which it contacts said worm gear and a second position where it does not contact said worm gear so that said worm gear can be easily moved when said nut means is not contacting said worm gear.
Claim 6
Dependent Claim
35 words
The manually operated handle of claim 4 wherein said nut means subtends less than 180° around said worm gear and said nut means is vertically slidable in and out of contact with said worm gear.
Claim 7
Dependent Claim
33 words
The manually operated handle of claim 5 wherein said nut means is moved vertically by a rotatable cam held by said handle body and said nut means has a cam contacting surface thereon.
Claim 8
Dependent Claim
292 words
A manually operated handle for panoramic cameras comprising: a handle body having a central opening, said handle body having a vertical axis; a central shaft held by said handle body, said central shaft having a central axis parallel with the vertical axis of said handle body, said central shaft having an upper portion affixable to a panoramic camera and said central shaft being rotatable; gear means affixed to said central shaft, said gear means having an axis of rotation at said central axis of said central shaft, said gear means being connected to said central shaft by a first one-way clutch which causes said central shaft to turn with said gear means when said gear means is turned in a first direction and permits said gear means to turn freely when said gear means is turned in the direction opposite ot said first direction; rack means slidably held by said handle body, said rack means having teeth which mesh with said gear means and said rack means being mounted at a right angle with respect to the central axis of said central shaft; a second one-way clutch held by said handle body, said second one-way clutch contacting said central shaft and permitting it to turn only in a first direction, whereby when said rack means is moved in a first direction, said gear means turns said central shaft in a first direction and said second one-way clutch permits such turning, but when said rack means is moved in a direction opposite to said first direction, said first one-way clutch permits the gear means to turn freely with respect to said central shaft and said second one-way clutch prevents any turning of said central shaft in a direction opposite to said first direction.
