Abstract
Abstract An apparatus for supporting a camera and moving the camera in a plurality of scanning directions. A support sleeve is detachably affixed to a support surface and is telescopically engaged with a support shaft that rotates within the support sleeve and slides upwardly and downwardly with respect to the support sleeve. A compression spring is provided to resiliently support the support shaft within the support sleeve to absorb vertical vibrations. An extending arm having a rear shaft portion and a front arm portion is supported in a bearing block for axial rotation of the rear shaft portion. The bearing block is affixed to the top end of the support shaft so that the block rotates with the shaft to impart a swinging motion to the extending arm. A tilting shaft is vertically aligned with respect to the support shaft and is connected for adjustable rotation at the end of the front arm portion of the extending arm. A camera is detachably mounted at the bottom end of the tilting shaft. A counter-balance spring is disposed within the support shaft and associated tension adjust apparatus is affixed to the end of the rear shaft portion of the extending arm to adjust the tension of the counter-balance spring and to thereby apply an adjustable downward force to the end of the rear shaft portion of the extending arm to counter-balance the weight of the attached camera.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
231 words
Apparatus for supporting a camera and scanning the camera in a plurality of directions, comprising: a support sleeve; a support shaft telescopically engaging said support sleeve for rotating about a support shaft axis and sliding axially with respect to the support sleeve; means for resiliently supporting said support shaft in said support sleeve; extending arm means having a rear shaft portion and a front arm portion, the rear shaft portion supported for axial rotation in a bearing block means, the bearing block means pivotally connected to a top end of said support shaft for rotation with the support shaft about the support shaft axis and for adjustable pivotal movement about a pivoting axis; tilting shaft means connected at one end to an extending end of said front arm portion for adjustable tilting rotation and having means at an opposite end for supporting a camera; and a counterbalance spring means disposed within said support shaft for applying a counter-balancing force to an extending end of said rear shaft portion to counter-balance the weight of said camera, one end of said counterbalance spring means connected to said support shaft and an opposite end of the counterbalance spring means connected to a tension adjust means mounted for partial rotation on said rear shaft portion, said tension adjust means including means for adjusting the magnitude of the counterbalancing force applied by said counterbalance spring means.
Claim 2
Dependent Claim
231 words
Apparatus for supporting a camera and scanning the camera in a plurality of directions, comprising: a support sleeve; a support shaft telescopically engaging said support sleeve for rotating about a support shaft axis and sliding axially with respect to the support sleeve; means for resiliently supporting said support shaft in said support sleeve; extending arm means having a rear shaft portion and a front arm portion, the rear shaft portion supported for axial rotation in a bearing block means, the bearing block means pivotally connected to a top end of said support shaft for rotation with the support shaft about the support shaft axis and for adjustable pivotal movement about a pivoting axis; tilting shaft means connected at one end to an extending end of said front arm portion for adjustable tilting rotation and having means at an opposite end for supporting a camera; and a counterbalance spring means disposed within said support shaft for applying a counter-balancing force to an extending end of said rear shaft portion to counter-balance the weight of said camera, one end of said counterbalance spring means connected to said support shaft and an opposite end of the counterbalance spring means connected to a tension adjust means mounted for partial rotation on said rear shaft portion, said tension adjust means including means for adjusting the magnitude of the counterbalancing force applied by said counterbalance spring means.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 including means for detachably affixing said support sleeve to a support surface.
Claim 4
Dependent Claim
44 words
The apparatus of claim 1 including a platform detachably mounted in a vehicle and means for detachably affixing said support sleeve to said platform for extending at least the front arm portion of the extending arm means outwardly through an opening in the vehicle.
Claim 5
Dependent Claim
65 words
The apparatus of claim 3 wherein said means for detachably affixing includes, a flange bolted to said platform, said flange detachably connected to the bottom end of said support sleeve, and a ring clamp affixed to an upper portion of said support sleeve, said ring clamp having an extending arm, the arm detachably connected to a wall bracket affixed to a wall of said vehicle.
Claim 6
Dependent Claim
57 words
The apparatus of claim 1 wherein the extending end of said front arm portion includes a bearing means for rotatably supporting said one end of the tilting shaft means, said bearing means including a friction knob means operable to engage said one end of the tilting shaft means for preventing the rotation of the tilting shaft means.
Claim 7
Dependent Claim
131 words
The apparatus of claim 1 wherein said tension adjust means includes: bracket means having a sleeve portion for rotatably engaging said rear shaft portion, the sleeve portion of said bracket means having a circumferentially extending slot, pin means formed on said rear shaft portion and engaging said extending slot to allow said rear shaft portion to rotate while said sleeve portion remains stationary, threaded rod means rotatably mounted in said bracket means, tension adjust knob means engaging the top portion of said threaded rod means for rotating to adjust the vertical position of said threaded rod means, cable means affixed at one end to the bottom end of said threaded rod means and at the other end to said counter-balance spring means, and pulley means for rotatably supporting said cable means.
Claim 8
Dependent Claim
15 words
The apparatus of claim 1 wherein said means for resiliently supporting is a compression spring.
Claim 9
Dependent Claim
48 words
The apparatus of claim 1 wherein said bearing block means includes a friction bearing and a friction knob connected to said friction bearing, said friction knob operable to move said friction bearing into clamping engagement with said rear shaft portion to prevent the rear shaft portion from rotating.
