Abstract
The invention provides a twist-lock canting system for surveillance cameras comprising a tilt camera mount housing (a twist housing) rotatably joined at an angle to a pan housing base. The twist housing is fixed in the selected position, either upright or canted, using captive slot headed locking bolts. The twist housing is smoothly rotatable around an interface plane by means of interface beads protruding from a rim portion of the camera mount housing which seat into a complementary interface channel in the pan housing base. The adjustable canting system allows the camera mount to be positioned so the camera is capable of surveilling the otherwise "blind spot" around the mounting pole, an area especially vulnerable if there are any camera power or data access ports at its base.
Description
TWIST-LOCK CANTING MOUNT FOR SURVEILLANCE CAMERAS
SPECIFICATION
FIELD OF INVENTION
This invention relates to the general field of pan-tilt mounts for surveillance cameras and more specifically to a twist-lock canting mount.
BACKGROUND OF THE INVENTION
Pan / Tilt / Zoom (PTZ) security cameras are usually supplied in configurations necessary to install them either upright or inverted. When a camera is mounted in its upright position on top of a pole there will be a restricted view of the area immediately below the camera due to limitations in the cameras tilt rotation function, and the physical obstructions caused by the camera body itself.
One method to solve this problem is to place the camera in an inverted position similar to a standard dome camera configuration. This enables the camera to look directly down, but permits a blind spot caused by the mounting pole. In order to correct both of these issues the security camera can be "canted" by moving its yoke arms in to a 45 degree position, enabling the camera I
head to look directly downwards. Prior models use a canting system that relies on a skilled engineer with special tools to configure, and often requires that the camera and mount be taken off the mounting pole for disassembly.
BRIEF SUMMARY OF THE INVENTION
The new twist-lock canting system advantageously enables the installer or end user to cant the camera through 45 degrees quickly by himself, without the need for special tools or pre-information about the installation site. Canting is achieved due to the cameras pan body being comprised of two parts joined at a 22.5 degree angle. Rotation is carried out without the need for any disconnection of wiring or power, which enables the camera to also be canted easily after installation, advantageously saving time and money.

A cant locking pin is buttable against a cant stop member such that the tilt camera mount housing is permitted to turn 180 degrees with respect to the pan housing base, but not beyond.
The adjustable canting system allows the camera mount to be positioned so the camera is capable of surveilling the otherwise "blind spot" around the mounting pole, an area especially vulnerable if there are any camera power or data access ports at its base.
This system also allows continued panoramic surveillance around the mounting pole or fixture if there is accidental or intentional damage to the pole which alters its original alignment configuration, such as if the pole was hit by a vehicle.
The system is essentially a twist-lock canting system for surveillance cameras comprising a camera mount twist housing rotatably joined at an angled interface to a pan housing base, with alignable locking bolts and bolt receptacles to fix the system in either a canted position or an upright position. The angled interface is preferably at 22.5 degrees with respect to a horizontal plane of the pan housing base, in order that a longitudinal axis of the camera mount twist housing can be twisted to form a 45 degree angle with respect to the horizontal plane when twisted 180 degrees along a rotational interface plane.
A detailed preferred embodiment would be one in which:
a) the camera mount twist housing forms a tilt camera mount yoke at an upper end of the camera mount twist housing opposite a rotational interface lower end of the camera mount twist housing;
b) a 180 degree rotation cant position is defined by means of a positioning pin becoming abutted against a cant stop, such that the camera mount twist housing is permitted to turn 180 degrees with respect to the pan housing base, but not beyond;
c) the angled interface has a twist-lock ring inserted into a twist-lock seat of the pan housing, and locking bolt, and a locking bolt hole in line with the twist-lock channel;
d) the pan housing base has extruded flanges on opposite sides of the pan housing base that mate with complementary camera mount twist housing flanges on opposite sides of the camera mount twist housing, to permit a single pair of locking bolts to secure the housings into either an upright or canted positions;
e) the angled interface has an 0-ring in a channel to provide rotational guidance during a change from upright to canted position and to provide sealing against weather intrusion into the system along the rotational interface.

DETAILED DESCRIPTION
Figure 1 shows a 3D isometric view of an upright Fork Mounted Surveillance Camera. Figure 1 shows the camera head 12, yoke arm 14, a single unit pan body 16, and the mounting base 30.
Not shown is its central shaft connecting the mounting base 30 to a pan motor inside the bottom of pan body 16 which is the means by which the camera mount is able to rotate around the pan axis.
Figure 2 shows a 3D side view of the twist-lock canting mount 10 in its canted position, which is achieved by turning the twist housing 18 one hundred eighty (180) degrees around the pan housing along the interface plane 40. Figure 2 also shows the camera head 12, yoke arm 14, the mounting base 30, the pan locking bolt 32 and bolt carrier 36.
Figure 3 shows a side view of the twist-lock canting mount 10 in its upright position, with its twist housing 18 and pan housing 20. In this orientation, notice that the pan locking bolt 32 is free in its bolt carrier 36.
Figure 4 shows a side view of the twist-lock canting mount 10 in its canted position, with the twist housing turned 180 degrees from its position in Figure 3, around the axis of the interface plane 40. In this configuration, the pan locking bolt 32 can now engage the bolt receiver 38 in the twist housing 18 (not shown). On the opposite end of the twist housing 18 a cant locking bolt 34 can pass through a hole in the housing body and into a bolt receiver 38 in the pan housing 20, thereby securing the two housings together.
Figures 5 and 6 show front views of the twist-lock canting mount 10 in its respective upright and canted positions.
Figure 7 shows a side view twist-lock canting mount 10 in its upright position (without its camera head) while revealing the interface between the twist housing 18 and the pan housing 20.
Revealed is the pan locking pin 26, cant locking pin 28, and several hemispherical interface beads 22 which seat into a corresponding interface channe124 (shown in Fig.9).
Figure 8 shows a side view twist-lock canting mount 10 in its canted position (without its camera head) while revealing the interface between the twist housing 18 and the pan housing 20.
Revealed is the pan locking pin 26, cant locking pin 28, and several hemispherical interface beads 22 which seat into a corresponding interface channe124 (shown in Fig.9).
In the canted orientation however, notice that the cant locking pin 28 butts against the pan locking pin 26 so that the twist housing is only permitted to turn 180 degrees and not beyond.
Figure 9 shows an isometric 3D view of the pan housing 20 including a close-up of the radial interface elements along the surface of the interface plane 40. Shown is how the interface bead 22 mates into the interface channe124, thereby allowing consistent rotation around the interface plane 40.
Figure 10 shows the twist housing 18 and the yoke arm 14 in the canted position, and a cutaway view of the pan housing 20. Figure 10 also shows the twist-lock ring 44 which is inserted into the twist-lock seat 46 of the pan housing 20. The twist-lock ring 44 has an 0-ring channe148, and a twist-lock channel. In line with twist-lock channel there is locking bolt hole 52, which is a threaded hole to hold a locking bolt (not shown). The twist-lock channel also houses a locking pin 54 inserted into, and protruding from a blind hole which prevents the twist housing 18 from turning beyond 180 degrees. Notice that there is an offset of one diameter of the locking bolt so that the locking pin 54 prevents rotation beyond 180 degrees. The same parts and arrangement are shown in Figure 11, but with the twist housing 18 in the upright position.
A preferred embodiment of the twist-lock canting mount system 10 will now be described in more in detail. Canting is achieved due to the cameras pan body being comprised of two parts joined at a 22.5 degree angle as shown in Figure 7 for example. The headed locking bolts (32/34) are positioned in their respective slots by captive means such as plastic sleeves (not shown) and are used to lock the two halves together. The two halves the two parts are mated using a radial groove (22/24) and locking pin (26/28) mechanism. This mechanism has an ability to rotate 180 degrees only, and is limited to this rotation by the use of two security locking pins (26/28). By releasing the locking bolts the two halves of the pan body 16 can be rotated manually through 180 degrees resulting in a 45 angular cant in the pan body 16. Once "canted"
the two captive locking bolts can be re-tightened to secure the two housings into in the new position.
Other embodiments of the twist-lock canting mount system 10 include a locking system which employs mating extruded flanges along the radius of the pan housing 16 that permit a single set of locking bolts to secure the housings into either upright or canted positions. This is made possible when the mounting flanges replace the existing thickened area below the yoke arms 14 as shown in the illustrations. As long as one half of the flange becomes the bolt carrier 36 and the other the bolt receiver 38, and they are in the same position on the pan body 16, then the locking mechanism will only require a singe set of locking bolts. In the preferred embodiment shown, when the mount 10 is in the upright configuration, separate bolts and threaded receivers are required.
Another embodiment includes variations on the nature of the interface between the two housings. As shown in Figure 9, a hemispherical interface bead seats into the interface channel, thereby allowing easy rotation, unhampered by old 0-rings, or rust-welding.
However, the portion that fits into the interface channel may also be continuous, may have a triangular profile, or may have two channels which house an 0-ring. Note that unless there is some means to ensure that the two housings cannot separate while rotating; an 0-ring may become unseated, and also would require complete disassembly for replacement. The object of the interface is to permit controlled rotation of the housings and to secure its position when bolted. Other embodiments are not ruled out or similar methods leading to the same result.
The foregoing description of the preferred apparatus and method of installation should be considered as illustrative only, and not limiting. Other forming techniques and other materials may be employed towards similar ends. Various changes and modifications will occur to those skilled in the art, without departing from the true scope of the invention as defined in the above disclosure, and the following general claims.
