Object movement system and method
Moves objects through two/three dimensional space via at least one movement line coupled with opposing sides of a platform. The movement line(s) control the horizontal and vertical (Z-axis) motion of the platform. Displacing a portion of the movement line(s) allows vertical displacement of the platform. There is no need for complex computer control since Z-axis displacement is substantially independent of horizontal movement. Nested embodiments utilizing one or more line allow for three-dimensional movement of an object or angular displacement of the platform with respect to the vertical axis. A mounting beam for positioning and supporting the Z-axis and horizontal axis motors may also be positioned independently of the platform. Many useful devices may be attached to the platform. Some embodiments may utilize two lines to provide redundancy and some of these embodiments may only drive one of the two lines for Y axis movement.

BACKGROUND OF THE INVENTION1. Field of the Invention
Embodiments of the invention described herein pertain to the field of aerial cable rail systems. More particularly, these embodiments enable the movement of objects within two-dimensional and three-dimensional space.
2. Description of the Related Art
An aerial cable rail system is a system based on an elevated cable or line, along which objects are transported. Existing cable rail systems have relied on large fixed structures and/or complex control systems in order to facilitate the movement of objects. These systems fail to satisfactorily achieve the full spectrum of ease of control, compact storage, ease of transport, speed, load bearing, extensibility, maintainability and platform stability.
Any number of coordinate systems can be used in order to describe the path of an object as it moves through space. This document uses the terms Z-axis and Y-axis to denote vertical and horizontal directions respectively.
In U.S. Pat. No. 6,199,829 a device is described that follows a line. There is no mechanism for altering the Z-axis displacement of the mechanism moving along the line. The device is self propelled and is heavy.
In U.S. Pat. No. 5,113,768 a device for transporting a camera along a cable is described. The device must be secure enough to carry not only a camera but also a human photographer. The device is limited in the amount of Z-axis displacement that can be effected.
In U.S. Pat. No. 4,864,937 a point A to point B cable rail is described. The device possesses no means to descend in the Z-axis other than by placement of poles. The poles supporting the structure are placed at fixed heights in order to avoid objects on the ground.
In U.S. Pat. No. 6,145,679 a device is described that uses balloons to provide support for a highline. Items are transported along the highline. The balloons may be raised or lowered but are cumbersome in enclosed environments and stadiums where they would block the view of spectators. In addition, the speed at which items could be transported would be fairly slow since a balloon would have a large surface area and would not be capable of rapid horizontal movement.
In French Patent No. 992,069 a device is described which has no means for controlling the arc of travel of the supported object since all control is manual. In addition, no means for conveying messages or advertisements are contemplated and it appears that the device is intended for industrial operations where the stability of the supported object is of little concern.
BRIEF SUMMARY OF THE INVENTIONOne or more embodiments of the invention are directed to a mounting system configured to move objects throughout two-dimensional and three-dimensional space by using at least one line (e.g., rope, cable or other mechanism) that is optionally reeved about a mounting beam and coupled with both opposing sides of a platform either rotationally or fixedly and wherein the platform may comprise the object to be moved. One line, which may be coupled with the optional mounting beam, controls both the Y-axis motion and Z-axis motion of the platform and is designated the YZ movement line. A nested embodiment of the invention may comprise a second line or a portion of the first line that is mounted parallel or non-parallel with the first line as seen from above and may comprise an XZ movement line, or a second YZ movement line or any other axial combination with the Z axis. A buoyant embodiment may be configured by coupling the platform with a buoyant device (balloon for aerial based embodiments, or float for aquatic based embodiments, or ferromagnetic material for space based embodiments). Buoyant or non-buoyant embodiments may be nested with buoyant or non-buoyant embodiments in any combination or number. One and two line embodiments allow for one or both lines to be driven along the Y axis. In embodiments that drive only one of the two ropes, the other rope freely moves through the sheaves in the system to allow the other rope to move the platform.
In a single line embodiment configured to move an object for example along the Y axis and vertically in the Z axis for example, displacing a portion of the YZ movement line via the Z-axis motor allows traversal of the Z-axis of the platform. Readers should note however that the actual path of traversal may curve be curved as will be explained further in the Detailed Description. Moving YZ movement line through the sheaves of the system via the Y-axis motor allows for traversal of the Y-axis of the platform (although like the Z-axis, the path of traversal may actually curve). Although computer control may be utilized, there is no need for a complex computer control system since over a coverage area serviced by the platform the Z-axis displacement is substantially independent of Y-axis movement and Y-axis displacement is substantially independent of Z-axis movement. This means that moving an object away from a given support structure can be accomplished by simply rotating the Y-axis motor although the object may minimally vertically displace in the middle of the path between the support structures to a lesser or greater extent depending upon the amount of line injected into the system via the Z movement device. This makes for trivial control when the amount of line in the system is set to follow the path of a stadium for example since the object may be configured to rise and follow the contour of the stadium without operator intervention (e.g., when the object is near each support structure). Vertical motion of the object is along the Z-axis when the amount of line to the object is the same from each support structure (i.e., when the object is in the middle of the coverage area) and slightly curved when near the support structures. Since the vertical component of motion is typically used in the middle and typically deepest part of the coverage area, no horizontal adjustments are typically necessary for this type of vertical motion. In other words, the Z-axis elements in the system control the upward and downward motion of the object although there may be some minimal but predictable horizontal motion, and the Y-axis elements in the system control the motion of the object between support structures although the object may experience some minimal but predictable vertical displacement during this movement. In other embodiments, a highline may be utilized in order to keep the angle of the lines leading to the platform at a fixed angle that prevents the platform from lowering in the middle of the movement path. Embodiments of the invention that utilize a highline keep the angle of the lines to the platform constant by running the lines through a skate that rides on the highline. Other embodiments employ safety devices that allow for the skate to run into a line near the ends of the movement path in the Y axis that lifts chain in order to slow and eventually stop the skate and platform in case the operator or computer fails to stop the platform.
In addition to trivial control and since it is possible to command the line from one point, distantly located motors and electrical cables are not required. Many types of useful objects may be attached to a mounting platform including devices that require external power or devices that possess their own power and are operated via wireless signals. By moving the platform, the object is therefore moved. The terms platform and object as used throughout this document are generally interchangeable. The term line as used herein is meant to include cables or any other suitable element for object suspension.
To ensure the platform follows a linear path in the Y direction without Z axis deviation, one or more embodiments of the invention contemplate the use of a computer control system. The control system takes into account the displacement of the platform from the support ends and adjusts the Z axis displacement during Y axis traversal. This allows the platform to travel in a straight line through three-dimensional space which may be important when using embodiments of the invention in locations that do not allow for an arced path.
Creating a two axis movement configuration from only one line driven from a point distantly located from the platform provides the advantages of allowing the motors to be large, power cables to be short and located near a large generator and optional control computer. Maintenance is readily performed in one location. The Z movement device in the system may also utilize a pulley arrangement that multiplies the Z-axis travel or may be constructed from levers, fulcrums, hydraulic or electronic actuators or any other device which can displace line.
It is feasible to configure the system to move objects along the Y and Z axes by using motors mounted at one support point, on or near the ground, to drive the lines. Embodiments of the invention use motors that connect to a generator, while other embodiments used in areas where power is readily available may use standard utility power. Generators used in embodiments of the invention can be as large as the application requires for achieving the required platform speed. The sheaves employed in the system may contain high speed bearings and are may be configured to capture the line in order to prevent derailing in order to add a degree of safety to the system. The drive pulleys attached to the motors comprise grooves that grip the line in order to prevent slippage. Any known means of driving line may be substituted for grooved pulleys.
For the purposes of this disclosure the use of the word motor signifies a motor connected to a drive pulley or drum winch. This assumption is made for purposes of illustration since it is well known in the art that the motor must drive any of a number of attachments to actually engage and move line. The system can be scaled to any size by employing longer lines and moving the attachment points or support structures.
Embodiments of the invention may be nested in order to support and move multiple independent or dependent objects. Dependent objects may for example comprise a pole coupled with a plurality of reevings that may keep a pole aligned vertically or may be moved independently in order to angle the pole with respect to any axis. Rigid couplings with a fixed distance between a plurality of reevings coupled to the pole may be utilized or non-rigid dependent couplings may also be utilized including telescoping poles or elastic bands for example. A plurality of lines irrespective of reeving may be coupled with a pole in order to provide a platform for a microphone for example. By offsetting the nested reevings about the vertical axis, for example orthogonally view respect to a viewpoint above the nested reevings, it is possible to move an object in the Y or X axes using coordinated control between each nested embodiment. In this manner, three-dimensional movement may be accomplished. Two rope systems may employ four associates of the lines with the pole. The associations may be fixedly attached or the associations may allow line movement through sheaves attached to the pole.
Independent objects may moved independent of one another and may also for example be controlled by one computer in order to avoid collisions between the independent objects. Collision sensors may be coupled with any element in the system in order to provide for collision avoidance with another object suspended and moved by another reeving instance, or with a stationary or moving object not associated with an embodiment of an invention as long as the position of the object is known to the system. Acoustic, optical or radar sensors, i.e., collision sensors, may be coupled anywhere within the system in order to reposition the supported object and/or line(s) in order to avoid a collision with a soccer ball, baseball, football or other sporting implement such as a javelin, hammer, shot put, or any other object that is capable of being detected. In pre-planned movements involving simulation, collision detection may be utilized in order to avoid a collision with an object that is sensed during actual movement of the physical embodiment followed by either exiting the pre-planned flight path or returning to the pre-planned flight path after avoidance.
BRIEF DESCRIPTION OF THE DRAWINGS
FIGS. 19A-G show one and two line realizations by selectively coupling line sides to one another and an exemplary Z movement device at which the realizations may be achieved.
Embodiments of the invention are directed to a Mounting System Reeved to Move an Object in Two-Dimensions and Methods Relating to Same. In the following description numerous specific details are set forth in order to provide a more thorough understanding of embodiments of the invention. It will be apparent, however, to an artisan of ordinary skill that the present invention may be practiced without incorporating all aspects of the specific details described herein. Any mathematical references made herein are approximations that can in some instances be varied to any degree that enables the invention to accomplish the function for which it is designed. In other instances, specific features, quantities, or measurements well-known to those of ordinary skill in the art have not been described in detail so as not to obscure the invention. Readers should note that although examples of the invention are set forth herein, the claims, and the full scope of any equivalents, are what define the metes and bounds of the invention.
The term line as used herein is also meant to refer to a cable or other flexible element that can be adapted for use as described herein. Moreover the use of the term path as related to Y-axis or Z-axis movement should not be limited to a linear path but may include a curved path. For example, elements of the system described as Z-axis or Y-axis related have as their primary control motion associated with their respective axis, although with curved paths, e.g., the Z movement device may actually introduce some Y-axis motion into the moved object and visa versa. Therefore although the terms Z-axis movement and Y-axis movement refer to moving an object primarily in the respective Z-axis and Y-axis, in reality the paths through space may be curved depending on where in the system the moved object is and under what type of movement it is undergoing. For example the Z-path of motion of the platform may be nearly identical to the direction of the Z-axis when the platform is equidistant between the two support structures. The path of the platform when asserting the Z movement device is slightly curved when the platform is near one of the support structures. The path between support structures may be very nearly linear when the amount of line in the system is set to provide the object with the highest possible height. Embodiments employing a highline avoid Z-axis drop in the middle of the path.
Any number of coordinate systems can be used in order to describe the path of an object as it moves through space. This document uses the terms Z-axis and Y-axis to denote vertical and horizontal directions respectively. The upward and downward path of an object moved by embodiments of the invention is not required to follow the exact vertical Z-axis and the path between support structures of an object may or may not follow the exact horizontal Y-axis as the object is moved when the amount of line in the system is kept constant. In general, on a first order approximation, for a given amount of line injected into the system, the path between support structures of an object being moved by embodiments of the invention is that portion of an ellipse lying beneath and between the support structures. With more line in the system, the path between support structures followed by an object becomes more circular or dipped in the middle.
Embodiments of the invention move objects through two-dimensions using one line. The line is coupled with opposing sides of a platform and either attaches to the platform or to a Z movement device. The line is driven by a motor and pulls the platform which may comprise an object from one side of the Y-axis to the other. The Z movement device displaces the line to or from the system in order to move the object primarily in the Z-axis. The Z movement device may be a lever, a screw-drive, block and tackle, or any other mechanism which can be configured to displace line. A motor driving the line may comprise a stepping motor or standard motor with a brake system in order to lock motion when the motor has stopped rotating. Any type of device that can move line can be used in place of a motor. There is no need for a complex computer control system since the Z-axis displacement is substantially independent of Y axis movement over a coverage area meaning that as the platform carrying the platform moves to the middle of the area of coverage in Y space, the Z-axis displacement is the deepest, see
Platform 124 is supported and is moved in two dimensions by one line. The line forms a “V” shape when viewed from the perspective of
Z movement device 104 is coupled with YZ movement line side 19a. Sheave 172 rides on YZ movement line side 19b. By rotating Y-axis motor 102 (attached to a bull wheel that drives the line but is not shown for ease of viewing), thereby decreasing the amount of line on YZ movement line side 19a, which increases the amount of line on Y movement side 19b, the platform moves mainly in the negative Y direction, or to the left as shown in the figure.
Z movement device 104 can be any mechanism which can displace sheave 174 and is not required to be a line, but rather can be a screw drive, hydraulic system, fulcrum or any other device capable of moving sheave 174. Z movement motor 101 may be utilized to power any type of Z movement device desired. Y-axis motor 102 drive pulley is not shown for ease of illustration. Drive pulleys and drum winches are well known to those skilled in the art and embodiments that minimize line wear and provide anti-derailing features may be interchanged to drive the line in the system. Any device that can pull move line through it can be used in place of a drive pulley or bull wheel.
An embodiment of the invention can run fiber optics cables or power cables along YZ movement line side 19a or 19b from support structure 110 to platform 124. Support structure 112 can alternatively supply power to the platform in the same manner. Platform 124 may alternatively house devices with collocated power supplies negating the need for external power cables. Devices attached to platform 124 may include wireless or other remote controlled devices.
Note that Z movement device 104 can comprise a sequence of pulleys for multiplying the Z-axis traversal, and may also utilize a block or other device for disabling travel in case of breakage within Z movement device 104. By placing a backup means of limiting the upward travel of sheave 174, the platform can be configured to never reach the ground beneath it even if a failure at or beneath Z movement device 104 were to occur.
Y movement in the positive Y direction, to the right in the figure, is accomplished by rotating Y-axis motor 102 counter-clockwise in the diagram. As Y-axis motor 102 rotates counter-clockwise, line side 19b moves down from sheave 171 that is coupled with support structure 110 (not shown for ease of illustration) and from sheaves 172, 173, 174, 175. This pulls platform 124 to the right in the figure, in the positive Y-axis. As line side 19b travels upward from Y-axis motor 102, line side 19a heads up to sheave 176 and to platform 124. The one line in the invention is designated with two reference characters 19a and 19b to signify which side of the platform the line is connected to. The arbitrary dividing point for the designation is at Y-axis motor 102. Note that sheaves 171, 176, 173 and 175 may be eliminated in embodiments of the invention that utilize motors mounted in supports 110 and/or 112. One skilled in the art will recognize that other sheaves may be moved or eliminated while keeping with the spirit of the invention. Reversing the direction of Y-axis motor 102 pulls platform 124 in the negative Y-axis direction, to the left in the diagram.
Retracting Z movement device 104 raises platform 124 primarily in the vertical direction and visa versa. As Z movement device 104 extends, YZ movement line side 19b moves upward into sheaves 173 and 175 that are coupled with support structure 112 (again not shown for ease of illustration). Since both sides of platform 124 have increased line length, the platform lowers. Motion of the Z movement device in the opposite direction raises the platform.
Retracting Z movement device 104 raises platform 124 primarily in the vertical direction and visa versa. As Z movement device 104 extends, YZ movement line side 19a moves upward into sheave 173. The line does not move into sheave 175 since the next span is to Y-axis motor 102 which is not a free rotating sheave. As line moves to platform 124 from sheave 173, downward force from platform 124 on sheave 172 pulls line side 19b from platform 124 into sheave 181 and through sheave 172. Since both sides of platform 124 have increased line length, the platform lowers. Motion of the Z movement device in the opposite direction raises the platform.
Rotating Z-axis motor 101 which in turn rotates this embodiment of Z movement device 104 (here a two wheel winch), causes an increase the length of deployed line in the system on line sides 19a and 19b lowers the platform in the Z-axis direction. As Z movement device 104 rotates in one direction, YZ movement lines 19a and 19b move upward into sheave 173 and 175 respectively. Sheaves 173 and 175 may be coupled with support structure 110 (not shown for simplicity). As line moves to platform 124 from sheave 173 into sheave 400, and from sheave 175 to sheave 402 and into sheave 401, both sides of platform 124 have increased line length, and hence the platform lowers. Operating the Z movement device in the opposite direction raises the platform.
Rotating Z-axis motor (not shown for brevity) coupled with Z movement device 104 here a winch, causes an increase the length of deployed line in the system on line sides 18b and 19 which lowers the platform in the Z-axis direction. As Z movement device 104 rotates in one direction, YZ movement lines 18b and 19 move upward into sheave 453 and 452 respectively. As line moves to platform 124 from both sides of platform 124, the platform lowers. Operating the Z movement device in the opposite direction raises the platform. The lines 18a/b and 19 attached to platform 124 as shown in
Rotating Z-axis motor (not shown for brevity) coupled with Z movement device 104 here a winch, causes an increase the length of deployed line in the system on line sides 18 and 19a which lowers the platform in the Z-axis direction. As Z movement device 104 rotates in one direction, YZ movement lines 19a and 18 move into sheaves 400 and 400n respectively. Line 18 continues to move out of sheave 400n to sheave 860 to sheave 861 to sheave 401n. As line moves to platform 124 from both sides of platform 124, the platform lowers. Operating the Z movement device in the opposite direction raises the platform. The lines on either side may be transposed up or down so that line sides 19a and 19b may both attach to sheaves at the top or bottom of the pole. Likewise, line 18 may also attach to sheaves on opposite sides at either the top or bottom of the pole. As shown in the figure line 18 attaches to sheaves across from 18 on the top and line 19a and 19b attach to sheaves across the bottom portion of the pole to line 19.
Extending Z movement device 104 vertically increases the length of deployed line in YZ movement line side 19a and 19b. This lowers the platform in the Z-axis direction. As Z movement device 104 increases in length, for example in the case of a screw block where a large screw rotates which unwinds a threaded block causing the block to rise, YZ movement line side 19a moves upward into sheave 173 while at the same time line side 19b moves upward into sheave 173a. The line does not move into sheave 175 or 175a since the next span is to Y-axis motor 102 which is not a free rotating sheave. As line moves to platform 124 from sheave 173, and 173a and 180, the platform lowers. Motion of the Z movement device in the opposite direction raises the platform.
Embodiments of the invention may comprise support structure 110 and 112 which may or may not comprise two sheaves each. Stadiums may contain support points, poles or other structures which may eliminate the need for separate support structures 110 and 112. More sheaves may be added to embodiments of the invention that require routing of line through obstacles. Any of the sheaves utilized in the system may comprise any device that can guide the line into the sheave securely.
An embodiment of the invention comprises a simple block and tackle utilized with the Z movement device 104. A block and tackle may be utilized in order to provide a Z-axis N-factor multiplier. Block and tackle assemblies are well known in the art and could readily be applied between Z movement device 104 and sheaves 173 and 175 in
Rotating Z-axis motor 101 which in turn rotates this embodiment of Z movement device 104 (here for example a two wheel winch), causes an increase in the span of deployed line sides 19a and 19b. Such increases lower the platform in the Z-axis direction. As Z movement device 104 rotates in the counterclockwise direction, line sides 19a and 19b move are reeled into the winch (or two wheel winch not shown for brevity) attached to Z-axis motor 104 from sheaves 400 and 402 via 401. Rotation of Z-axis motor in the opposite direction conversely lowers the platform.
Any additional instance of the embodiment of the invention comprising the line or lines reeved in the spirit of the invention whether or not identically reeved as the primary reeving is reeved is termed a nested reeving. Embodiments of the invention may be nested for example to allow more than one object to be moved within a given volume of space at the same time or to provide for an angular offset with respect to a plurality of platforms. Nested embodiments may be independent of one another, meaning that any two of the embodiments described herein may be utilized in the same general space as any other embodiment of the invention independently. Nested embodiments may also be dependent meaning that the platforms of the plurality of embodiments comprising a nested configuration are coupled in some way. Nested embodiments of the invention that are mounted on other embodiments of the invention are termed recursive embodiments. For example a beam embodiment may comprise a second embodiment hanging underneath the first embodiment with any angular offset for example. A dependent non-recursive embodiment in general comprises a coupling between the platforms or replacement of one or both platforms with a rod or pole that may be telescoping as per
Nested embodiments utilizing the reevings of
Y movement in the positive Y direction, to the right in the figure, is accomplished by rotating Y-axis motor 102 counter-clockwise in the diagram. As Y-axis motor 102 rotates counter-clockwise, line side 19b moves down into Y-axis bull wheel (not shown for ease of illustration) coupled with Y-axis motor 102 through sheaves located near the top of support 2001 and 2002. Line 19b heads up support 2002 from skate 2021 where the line is attached to the skate to effectuate movement. Line 19b travels out of the sheaves on support 2001, down support 2001 and across from support 2002, down support 2002 and to skate 2021. As this occurs, line is pulled from the right side of the sheave coupled to the right side of platform 124 through skate 2021. At the same time, line exiting the right side of Y-axis bull wheel attached to Y-axis motor 102 heads up support 2001 and over to skate 2020 and into the sheave coupled to the left side of platform 124. As line side 19b leaves Y-axis bull wheel attached to Y-axis motor 102, it becomes designated line side 19a on the right side of Y-axis motor 102. This motion of the single line in the system pulls platform 124 to the right in the figure, in the positive Y-axis. The arbitrary dividing point for the designation change from 19a to 19b on the two sides of the line is at the Y-axis motor. Z movement device 104 in this embodiment is a winch, however any device can be used that is configured to deploy and remove lengths of line sides 19a and 19b into the system. One skilled in the art will recognize that some sheaves may be moved or eliminated while keeping with the spirit of the invention. Reversing the direction of Y-axis motor 102 pulls platform 124 in the negative Y-axis direction, to the left in the diagram.
Rotating Z-axis motor (not shown for brevity) which in turn rotates this embodiment of Z movement device 104 (here a winch), causes an increase the length of deployed line in the system on line sides 19a lowers the platform in the Z-axis direction. As Z movement device 104 rotates in one direction, YZ movement lines 19a move upward over through skate 2020 into the sheave coupled to the left side of platform 124. Operating the Z movement device in the opposite direction raises the platform. Other embodiments may employ director sheaves as shown in
Rotating Z movement device 104 in the counterclockwise direction move rope 18 up support 2001 and across to skate 2020a and down to the sheave on the left side of platform 124, then back up to skate 2020a and across to support 2002 where line 18 attaches. Line 20 attaches to the right side of platform 124 and travels up through skate 2021a to sheaves on support 2002, back across to sheave coupled to support 2001 and back to skate 2021a where line 20 attaches.
Platform 124 can have many different apparatus attached to it to perform a variety of functions including but not limited to buoyant elements, stabilization devices, gimbals, camera equipment, mining loaders, ship-to-ship loaders, logging devices, ski lift seats, gondolas, body sensing flight simulator suits for allowing a person to simulate flying, reduced gravity simulator suits, lifting harnesses, munitions depot bomb retrievers, digital video equipment for security checks in railroad yards or nuclear facilities, robotic agricultural harvest pickers for quickly picking and storing grapes or other produce or any other device that benefits from repeatable placement and motion in two dimensional space. In another embodiment, platform 124 comprises a witness camera mounted pointing down from the platform, providing a picture from the viewpoint of the platform. Although shown with respect to highline embodiments, all of the embodiments described herein may utilize a chain safety by employing chain at an offset from support sheaves. For example, any of the embodiments described herein may run into a line that is vertically displaced and configured to engage the platform, sheaves coupled with the platform or the pole attached to the platform so that a chain is lifted. In one or more embodiments, when a Y movement motor achieves a high enough level of torque, the motor may switch off or trip a circuit breaker. As long as the chain is heavy enough with respect to the torque capacity of the motor, the line coupled with the chain will keep the platform from striking any object.
Sheaves coupled with platform 124 may comprise generators that are used to feed a platform based power system that allows the platform to derive power and/or regenerate power through movement of the platform. Power may also be supplied by an external power line that may be festooned along a line such as 18a, 18b, 19a or 19b in order to drive components coupled with the platform.
While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
