DETAILED DESCRIPTION

(11) With reference now to the drawings, and in particular to FIGS. 1 through 9 thereof, a new remotely controlled pulley transport system embodying the principles and concepts of the disclosed subject matter will be described.

(12) The radio controlled pulley 1 comprises; a support line 2, a platform 3 suspended from the support line 2, a propulsion system, The propulsion system 5 may be configured to cause the platform 3 to move along the support line 2 with the propulsion system 5 affixed to the platform 3, and a control system 4 for commanding the propulsion system 5.

(13) The support line 2 may be of any material capable of flexibly stretching between at least two support points 6 and supporting the weight of the platform 3 and the components placed on the platform 3.

(14) The platform 3 may be of any suitable shape and size required to accommodate a propulsion system 5 and a control system 4 for radio controlled pulley 1. To serve as a radio controlled pulley 1 the platform 3 must also accommodate a connection 22 for attaching items for transport 23. Items for transport 23 may be any item or items which may be attached to the connection 22. Items for transport 23 include, but are not limited to tool belts, buckets, and sheet materials.

(15) The radio controlled pulley 1 may be further equipped with a television camera.

(16) The propulsion system 5 comprises a motor 9, an energy storage system 10, a transmission system 11, and optionally a power supply 12. The motor 9 may be an internal combustion engine using a liquid or gaseous fuel such as gasoline, diesel fuel, propane or any fuel suitable to operate an internal combustion engine. The motor 9 may be an alternating current or direct current electric motor. The energy storage system 10 may be an electrical battery 13, or a tank 14 of an appropriate type for storing the liquid or gaseous fuel. In yet another embodiment the energy storage system 10 may be a wound spring 15. In short the motor 9 is any device which converts the energy stored in the energy storage system 10 to mechanical work used to propel the radio controlled pulley 1 along its support Line 2. The transmission is any mechanism which transmits mechanical energy from the motor 9 to the support line 2 to cause the radio controlled pulley 1 to move along the support line 2. In one embodiment the transmission system 11 would consist of a wheel 16 resting on the support line 2, connected by a drive belt 17 to a pulley 18 attached to and turned by the motor 9. In another embodiment the drive belt 17 and pulley 18 assembly would be replaced by a gear train 19. It will be recognized that there are a large number of ways by which the motor 9 can be connected to a drive wheel 16, or multiple drive wheels, to cause the radio controlled pulley 1 to move along the support line 2.

(17) One or more tensioning wheels may be included on the side of the support line 2 to increase the friction between the drive wheels and the support line 2. One or more of the drive wheels and tensioning wheels may be provided with treads to increase their grip on the support line 2.

(18) The optional power supply 12 is anything which captures or produces energy and supplies that energy to the energy storage system 10. In one embodiment this optional power supply 12 is a set of photo voltaic cells which supply energy to the electrical battery 13. In another embodiment the optional power supply 12 is an electrical battery charger which can be plugged into a convenient power source placed anywhere along the and sufficiently near the support line 2. It will be appreciated that this optional power supply 12 may take on many forms and can be envisioned for any of the energy storage systems 10 contemplated. This optional power supply 12 can be as simple as a slot to accommodate a winding key for the spring 15, as complex as photovoltaic cells to charge the electrical batteries, or anything in between.

(19) The control system 4 may be of a preprogrammed type or of a type which can be managed while the radio controlled pulley 1 is remote from the operator. In both cases the control system 4 interacts with the motor 9, transmission system 11 or both to determine the direction and speed at which the motor 9 causes the radio controlled pulley 1 to move along the support line 2. The preprogrammed type provides a means for the operator to provide control instructions while the radio controlled pulley 1 is close at hand and the control system 4 then executes the instructions provided by the operator. The preprogrammed control system 4 may be as simple as an on-off switch, as complex as a programmable computer, or any level of complexity in-between. The remote control system 4 allows the operator to control the radio controlled pulley 1 via electromagnetic or acoustic waves.

(20) In other embodiments of the disclosure, such as shown in FIGS. 6 through 9 and in particular in FIG. 9, a remotely controlled pulley transport system 24 includes a support line 2 and a transport apparatus 26 which is configured to be supported on the support line 2, such as by suspension from the support line. The transport apparatus 26 may include a platform which may comprise a housing 28, and the housing may be elongated in shape with an upper end 30 and a lower end 31 when supported on the line 2. The housing 28 may include a first side and a second side, and the first side may be for positioning toward the support line 2 and the second side may be for positioning away from the support line. The housing may define an interior.

(21) The transport apparatus 24 may also include a first wheel 32 which is mounted on the housing of the platform. The first wheel 32 may be configured to rest upon the support line. The first wheel 32 may function as a drive wheel and may comprise a sheave which may be removable to replace the wheel with perimeter grooves that are larger or smaller to accommodate various diameters of support line 2. Such replacement may be accomplished through the use of a quick connect structure between the wheel and the shaft on which the wheel is mounted. In some embodiments, the first wheel may be mounted on the housing 28 in a position such that substantially an entirety of the housing is positioned on a first side of a vertical plane 34 which passes through the support line when the first wheel engages the support line to suspend the housing from the line 2.

(22) The transport apparatus 26 may also include a propulsion device 36 which is configured to move the transport apparatus along the support line. This propulsion device may be connected to the first wheel to rotate the first wheel and the propulsion device may comprise a motor, although other means for rotating the first wheel may be employed. The motor may be positioned in the interior of the housing and may also include a power supply. The power supply may comprise a battery 38, and in some embodiments the battery may be rechargeable and may also be removable from the housing. In some illustrative embodiments, the housing may define a battery cavity 40 for removably receiving the battery 38. The battery cavity 40 may extend into the housing at the lower end 31 of the housing, which may function to move the center of gravity of the apparatus toward the lower end of the housing.

(23) The transport apparatus 26 may also include a second wheel 42 which is mounted onto the housing of the platform in a manner such that the support line is positionable between the first and second wheels. The second wheel may be positioned adjacent to the first wheel, but also may be spaced from the first wheel to thereby permit the support line to be positioned in a space between the first and second wheels. The second wheel may be mounted on the housing in a manner such that the second wheel is spring-biased toward the first wheel. In some embodiments, the second wheel 42 may have a diameter which is less than a diameter of the first wheel 32, and may also be removable to replace the second wheel with a wheel having a perimeter groove suited to the diameter of the support line being used with the transport apparatus.

(24) The transport apparatus 26 may also include a connection device 44 which is mounted on the housing of the platform and may be configured to removably connect to an object to be transported by the transport apparatus. The connection device may comprise a hook 46 which may be mounted on the housing such that the hook is positioned on a second side of the vertical plane 34 passing through the support line 2 when the first wheel 32 engages the support line. The connection device 44 may also include a spacing member 48 which is mounted on the housing of the platform and may have the hook 46 mounted thereon. The spacing member 48 may extend outwardly from the first or front side of the housing and may have an outboard end 50 located away from the housing. The hook 46 may be mounted on the outboard end 50. The position of the spacing member 48 may be adjustable along a length of the elongated housing between the upper 30 and lower 31 ends of the housing. The spacing member may be positionable on the housing at a location that is located between the first wheel and the lower end of the housing, and in some of the most preferred embodiments, between the second wheel and the lower end.

(25) The system 24 may also include a control assembly 4 which is configured to control operation of the transport apparatus. The control assembly may be configured to remotely control the apparatus operation. The control assembly 4 may include a receiver mounted on the transport apparatus and the receiver may include a receiver antenna. The control assembly 4 may also include a transmitter and the transmitter may include a transmitter antenna. The control assembly 4 may include a control housing and the transmitter may be incorporated into the control housing. The control housing may be separate from the transport apparatus and thus may be relatively freely movable with respect to the transport apparatus to provide the remote control aspects of the disclosure.
