Description




FIELD OF THE INVENTION




The present invention relates generally to traffic marker devices or safety cones used to alert or divert vehicles, watercrafts, aircrafts and pedestrians to pass safely around hazards, obstacles or other areas. More particularly, the present invention relates to a device and method for automatically placing safety cones to areas where it is necessary to alert or divert vehicles, watercrafts, aircrafts or pedestrians.




BACKGROUND




Traffic or safety cones are routinely used to direct motorists and pedestrians away from obstacles or dangerous areas. Safety cones are usually brightly colored, hollow conical shaped devices made of a synthetic, rubber or other plastic (See for example U.S. Pat. No. 2,333,273 to Scanlon et al.). Commonly, safety cones are placed by an individual who is manually delivering and/or placing these cones to a particular place on, for instance, but not limited to, a freeway, a road, a street, an intersection, or the like. In other cases, a vehicle can take an individual to a particular place, however it is still the individual that needs to place the safety cones by hand once the vehicle has arrived at that particular place. This task is labor-intensive, slow and could easily result in chronic back-injuries in those individuals who perform such a task routinely. Automation of this task would be preferred. However, with the current safety cones, being fairly rigid and having a tendency to easily fall over, delivering the cones in an automatic fashion from a moving vehicle would not be practical. The reason that this would not be practical is due to the chance for the current relatively rigid safety cones to remain upright upon placement would not be that high when they are delivered and placed from a moving vehicle. Furthermore, if such an automation would take place with the current fairly rigid safety cones, and since some or most of these cones would not able to maintain their upright position, the fallen cones need to be re-placed to their upright position by an individual so that these cones can be useful to the public as safety cones. Therefore, there is first a strong need for improved safety cones or marker devices. Second there is a strong need for an apparatus and method to automatically deliver and place such improved safety cones.




SUMMARY OF THE INVENTION




The present invention provides a device, method and system for automatically delivering and placing a safety cone to a position on a ground surface from a moving vehicle. The key idea of the present invention is that there is a receptacle that holds a plurality of safety cones. A releasing means which is attached to the receptacle is controlled and advances the safety cones in an automatic and controlled fashion, one-by-one, to different locations on a road, street, freeway, intersection, or the like.




The device of the present invention includes a receptacle for holding a plurality of safety cones. The preferred selection of safety cones that could be used in the present invention is a safety cone that includes a flexible means positioned over a base and wherein the bottom of the flexible means is attached to the base. The device further includes a releasing means for releasing one out of the plurality of safety cones to a position on a ground surface. The releasing means advances one safety cone to a position on the ground, while it prevents the remainder of the plurality of safety cones from being released from the receptacle. In order to control the timing of each release the device of the present invention also includes a control means to control the releasing means.




The method of the present invention for automatically placing a safety cone includes the step of providing a receptacle for holding a plurality of safety cones. The method further includes the step of providing a releasing means for releasing one out of the plurality of safety cones, one at a time, from the receptacle to a position on a ground surface, while preventing the remainder of the plurality of safety cones from being released from the receptacle. A control means is provided to control said release of each safety cone.




The system of the present invention for automatically delivering and placing safety cones from a moving vehicle includes a receptacle for holding a plurality of safety cones, whereby the receptacle is attached to the moving vehicle. The system further includes a releasing means for releasing one out of the plurality of safety cones, one at a time, to a position on a ground surface. During the release the releasing means prevents the remainder of the plurality of safety cones from being released from the receptacle. The system further includes a control means to control the releasing means and placement of the plurality of safety cones at different positions on the ground surface.




In view of that which is stated above, it is the objective of the present invention to automatically place safety cones to a ground surface.




It is still another objective of the present invention to automatically deliver safety cones to a ground surface from a moving vehicle.




It is still another objective of the present invention to provide a receptacle attached to a vehicle for holding a plurality of safety cones that could be placed on a ground surface.




It is still another objective of the present invention to provide a releasing means for releasing means for releasing the safety cones on-by-one to different position on a ground surface.




It is yet another objective of the present invention to provide a control means to control the timing of the release of the safety cones.




It is yet another objective of the present invention to provide one or more sensors to further automate the delivery and placement of safety cones.




It is yet another objective of the present invention to use safety cones which each include a flexible cone part that is placed over a base and whereby the bottom part of the flexible cone part is attached to the base.




The advantage of the present invention is that it automatically takes care of the placement of a plurality of safety cones. There would no longer be a need for a person to manually deliver and place the safety cones. Human interaction would only be required to initiate and stop the release of one or more safety cones. The present invention therefore provides for increased safety. The present invention would decrease or even eliminate the number of fatal or non-fatal accidents as well as chronic injuries of road-workers that are involved in placing safety cones. Furthermore, the time it takes to deliver and place the safety cones will be significantly decreased compared to manual placement. It also allows the driver of the vehicle delivering the safety cones to no longer worry about the cone placement and could therefore pay more attention to the accident or event that initiated the safety cone placement.

Accordingly, the following preferred embodiment of the invention is set forth without any loss of generality to, and without imposing limitations upon, the claimed invention.




The present invention provides a device, method and system for automatically delivering and placing a safety cone to a position on a ground surface. The key idea of the present invention is that there is a receptacle that holds a plurality of safety cones. A releasing means which is attached to the receptacle is controlled and advances the safety cones in an automatic and controlled fashion, one-by-one, to different locations on a road, street, freeway, intersection, or the like. The present invention provides for increased safety. The present invention would decrease or even eliminate the number of fatal or non-fatal accidents as well as chronic injuries of road-workers that are involved in placing safety cones.





FIG. 1

shows a device


100


that includes a receptacle


110


for holding a plurality of safety cones


120


. Device


100


is attached to a vehicle


130


that is carrying device


100


. Device


100


could be attached to any location of vehicle


130


. However, the preferred location of attaching device


100


to vehicle


130


is somewhere at the back or near the back of vehicle


130


. The ultimate location for device


100


is dependent on the type of vehicle and/or the type of service the vehicle is intended to provide. It could, for instance, be possible that the best location for device


100


is at one of the sites of vehicle


130


. Device


100


could be attached to vehicle


130


with any type of connecting or attaching means


140


that provides a rigid, movable, adjustable and/or pivotal connection or attachment. As a person of average skill in the art would readily appreciate, connecting or attaching means


140


could further include means (not shown), such as a linear or rotary motor, to translate and/or rotate device


100


around its X-, Y-, and Z-axes to establish the proper position of device


100


relative to vehicle


130


.

could take any type of shape, such as, but not limited to, a square


210


, rectangular


220


, cylindrical


230


or the like as show in FIG.


2


. Furthermore, receptacle


110


could be an enclosed structure or a wire frame structure as long as the plurality of safety cones can be held inside receptacle


110


without falling out receptacle


110


or tipping over. The requirement for receptacle


110


is that it needs to allow a user to place a plurality of safety cones inside receptacle


110


. Another requirement for receptacle


110


is that it has an opening


210


A,


220


A or


230


A or a mechanism (not shown) to create an opening through which the safety cone, that is about to be released and placed to a position on a surface, could pass. Opening


210


A,


220


A or


230


A is preferably situated at the bottom of receptacle


110


. Yet another requirement for receptacle


110


is that it has enough height H so that it could host enough safety cones that are adequate for the intended activities or events without the safety cones tipping over or falling out of receptacle


110


. Safety cones


120


are preferably stacked inside receptacle


110


.




The receptacle further includes a releasing means for releasing one out of the plurality of safety cones at a time to a position on a ground surface, while the releasing means prevents the remainder of the plurality of safety cones from being released from the receptacle. As a person of average skill might readily appreciate, releasing means could therefore also be referred to as a holding and releasing means. In general, the receptacle includes one or more elements that are movably attached to the receptacle to release one out of the plurality of safety cones. The same one or more elements could also be used to prevent the remainder safety cones from being released from the receptacle. However, as a person of average skill in the art would readily appreciate, the receptacle could also have one or more elements specifically designed for releasing the safety cone, whereas other one or more elements could be specifically designed for holding the remainder safety cones in the receptacle. The one or more elements could move back-and-forth between a holding position to hold the plurality of safety cones and a releasing position to release the one out of the plurality of safety cones while preventing the remainder of safety cones from being released from said receptacle. The one or more elements could also be arranged in a pattern (such as a propeller-shape) whereby the elements are attached to a common structure. It is then the common structure that is movably attached to the receptacle.





FIGS. 3-5

show exemplary receptacles


300


,


400


and


500


respectively, including exemplary releasing means


310


,


410


and


510


respectively, that are capable of holding a plurality of safety cones and capable of releasing the safety cones, one at a time. Releasing means


310


,


410


and


510


are attached to receptacle


300


,


400


and


500


, respectively as shown by exemplary embodiments in

FIGS. 3-5

. Releasing means is preferably attached near the bottom part of delivering device. The key idea of releasing means is that once releasing means advances, it releases a safety cone, the remaining safety cones in the delivering device then advance downward until it is their turn to be released. As a skilled artisan in the art to which this invention pertains would readily appreciate, several different releasing means could be used and the present invention is in no way limited to the particular embodiments


310


,


410


and


510


as they are described below with reference to

FIGS. 3-5

.





FIG. 3

shows receptacle


300


with releasing means


310


. Releasing means


310


includes one or two “propeller-like” devices


320


that rotate around the Y-axis. If two “propeller-like” devices


320


are used then both “propeller-like” devices


320


are aligned as shown in FIG.


3


and advance in the same manner as a person of average skill in the art would readily appreciate. The exemplary embodiment shown in

FIG. 3

is not limited to one or two “propeller-like” devices


320


, since it could also be possible to have a plurality of “propeller-like” devices


320


distributed over the bottom or the vertical length of delivering device


300


. In this example of

FIG. 3

, the propeller-like device could be seen as one or more elements, in this case four, that are attached to a common structure. The common structure is then movably attached to receptacle


300


.





FIG. 4

shows receptacle


400


with releasing means


410


. Releasing means


410


includes one or two elements


420


that could either rotate downward around the Y-axis, translate in-and-out along the X-axis, rotate around the Z-axis, or a combination of translation(s) and/or rotation(s) around the different axes. If two elements


420


are used then both elements


420


are aligned as shown in FIG.


4


and operate similar, as a person of average skill in the art would readily appreciate. Elements


420


are not limited to a particular shape and could for instance have a triangular shape, square shape, flat shape or round shape. The exemplary embodiment of

FIG. 4

is also not limited to one or two elements


420


, since it could also be possible to have a plurality of elements


420


distributed over the vertical length of delivering device


400


.





FIG. 5

shows receptacle


500


with releasing means


510


. Releasing means


510


includes a spiral element that could rotate around the Z-axis. The idea here is that the safety cones are placed in spiral element, preferably in a collapsed position


520


. The safety cones will be released once the spiral rotates. Releasing means


510


advances a safety cone, as one of average skill in the art would readily appreciate. Once the safety cone is released or being released, the safety cone expands from its collapsed position.




As shown in

FIG. 6

, receptacle


610


places one safety cone at the time to a particular place. For instance, safety cone


620


was released and delivered at place X


1


at time T


1


, safety cone


622


was released and delivered at place X


2


at time T


2


, and safety cone


624


is being released and delivered at place X


3


at time T


3


. As a person of average skill would readily appreciate, device


610


could place one or more safety cones as many as there are hosted in receptacle


610


. As will be discussed below in more detail, the present invention would preferably require the use of safety cones that have a flexible cone part that could be easily bend or undergo perturbations during the placement of the safety cones without jeopardizing a correct, upright placement of the safety cones as is shown in FIG.


6


. In this case, the height of device


610


with respect to the ground would then not really matter. Important to note is that the weight of the bottom part or base of the safety cone ensures the safety cone to move downwards when it is released and the flexible to part would automatically follow the position of the base of the safety cone. Once the base is placed on the ground and the flexible top part leaves receptacle


610


, then the flexible top part flops up to its upright position.




In order to release a safety cone, a control means


720


is included to receptacle


710


to control the releasing means as shown in FIG.


7


. Control means


720


controls the timing of the release of one out of the plurality of safety cones. Control means


720


is not limited to controlling the timing of one safety cone, since it could easily control the timing of two or more safety cones. In case a plurality of safety cones would need to be placed, then control means


720


could control the release of the safety cones, one-by-one, so that they are placed at equal distance, variable distance from each other, or a combination of equal or different distances.




As shown in

FIG. 7

, device


710


includes a control means


720


to control the operation of device


710


to release a safety cone, one at the time. Control means


720


could be in close proximity to device


710


or integrated with device


710


, however the present invention is in no way limited to the position of control means


720


relative to device


710


as long as control means


720


could be controlled or operated by a user, as one of average skill in the art would readily appreciate. However, having control means is close proximity to the driver of the vehicle would be preferred as it is shown by control means


730


, so that the driver can continue to drive the car and/or focus on the situation or accident that initiates the placement of safety cones, while releasing safety cones. Control means


810


communicates with device


820


either via an electrical wire connection


812


or via a wireless connection


814


as shown in FIG.


8


.




As shown in

FIG. 9

, control means could include a small touch screen/panel


910


with a start and stop button, a switch box


920


with one or more switches


925


, or the like, to control a release of one or more safety cones. However, control means of the present invention is not limited to touch screen/panel


910


or a switch box


920


, since it could also be a personal digital assistant


930


with a touch-screen or display


932


and a keyboard


934


, or other computer device such as, but not limited to, a laptop


940


to communicate with the releasing means. Furthermore, control means could also receive voice commands (not shown), which are then interpreted by the control means and communicated to the releasing means. The basic parameters to be controlled by the control means are the start and stop of the release of a single safety cone or a plurality of safety cones in continuity. However, as one of average skill in the art would readily appreciate, the control means could be more sophisticated in that it could automatically control the timing of subsequent safety cones once the start signal has been provided. For instance, one or more sensors that could provide, for instance, distance information to the control means could be used to sense the distance traveled by the vehicle and then after the vehicle travels a certain distance, the next safety cone could be released. In the example of a more sophisticated control, the control means then only triggers the start of the release of the first safety cone and then the subsequent release of one or more safety cones follows automatically in a controlled fashion with the cones being released and placed at a preferred distance from each other (see for instance X


1


and X


2


in FIG.


6


). The distance can, for instance, be programmed or preset in the control means, since it could be easily gathered or calculated by the control means, given the feedback or sensory information over the distance, time and/or speed that the vehicle has traveled, as one of average skill in the art would readily appreciate. Another example is that control means could include one or more schedules to schedule the release and delivery that could either be programmed or entered for a particular event. In other words, a user could either manually control the start and stop by manually control the delivering device, or could control the start and stop of an automatic release schedule, whereby the automatic release schedule includes a small control program using sensory or feedback information as input and signals to control means as output. As one of average skill in the art would readily appreciate, such an automation would be desirable and preferred, since a person driving the vehicle would no longer have to worry about the correct placement of the safety cones and whether or not they are falling over or not. Furthermore, such an automated delivery schedule would be much faster than current procedures of manually delivering the safety cones. It would be more efficient, faster and also reduces or even eliminates the physical stress on individuals who used to be reseponsible for placing the safety cones manually. The present invention could also include sensors that check or verify whether a safety cone is actually released and placed correctly. Examples of such sensors are, for instance, different types of optical sensors.




The type of safety cone to be used in combination with the device of the present invention is a safety cone that would stay upright upon release from the receptacle. Furthermore, as mentioned above, the present invention would also require the use of safety cones that could be easily bend, or undergo perturbations during the placement of the safety cones without jeopardizing a correct, upright placement of the safety cones as is illustrated in FIG.

.

FIGS. 10-12

show preferred embodiments of a safety cone that would be preferred in combination with the device of the present invention (The reader is referred to U.S. patent application Ser. No. 10/131,316 filed on Apr. 23, 2002 for more details regarding these flexible safety cones; U.S. patent application Ser. No. 10/131,316 is incorporated for all that it discloses). However, as a person of average skill in the art would readily appreciate, the present invention is not limited to this particular safety cone as long as it could be easily released to an upright and stable position without tipping or falling over upon release from the receptacle.




As shown in

FIG. 10

, safety cone


1000


of includes a base


1010


and a flexible means


1020


that is positioned over base


1010


. The bottom part


1030


of flexible means


1020


is attached to base


1010


. As a person of average skill in the art would readily appreciate, different means and ways could be employed to attach or combine flexible means


1020


and base


1010


. Flexible means


1020


is, for instance, but not limited to, a coil and maintains in an original upright position in absence of a natural or traffic perturbation as shown in FIG.


10


. However, flexible means


1110


deviates from this original position in presence of a natural or traffic perturbation


1100


and


1200


as shown in

FIGS. 12 and 13

, respectively, or a perturbation from being released from a receptacle or being placed to a ground surface from a moving vehicle as shown in FIG.


6


. Moreover, the flexible means restores from this deviated position back to the original position after the perturbation disappears or is removed as it is taught in the pending application. Furthermore, the safety cone includes a cover


1040


to cover flexible means


1020


and


1110


as shown in

FIGS. 10-11

, respectively. The advantage of the safety cone over previous rigid safety cones is that the flexible safety cone can more easily resist various types of perturbations without falling over due to its flexible design. Therefore these safety cone would be an excellent candidate and preferred safety cone or marker device that could be used for automatically placing safety cones from a moving vehicle at a particular place on the road, freeway or any other area, since the chances of falling over are significantly reduced or minimized.




The present invention has now been described in accordance with several exemplary embodiments, which are intended to be illustrative in all aspects, rather than restrictive. Thus, the present invention is capable of many variations in detailed implementation, which may be derived from the description contained herein by a person of ordinary skill in the art. For instance, as it has been taught in U.S. patent application Ser. No. 10/131,316 filed on Apr. 23, 2002, the safety cones could also include a light source that could be automatically activated upon release and placement to a position on a ground surface. Another variation is shown in

FIG. 13

whereby receptacle


1310


further includes a guiding means to guide the safety cones within receptacle


1310


. Guiding means could, for instance, include one or more surfaces


1320


whereby each of the surfaces


1320


are movably connected to receptacle


1310


by, for instance, spring loaded mechanisms


1330


. The key idea is that the guiding means guides the safety cones in a position so that the safety cones maintain upright and are nicely guided downward every time a safety cones is released. As a person of average skill in the art would readily appreciate, a variety of mechanisms could be employed to movably connect surfaces


1320


and the present invention is not limited to spring loaded mechanisms


1330


. Furthermore, the present invention is also not limited to surfaces


1320


as shown in

FIG. 13

since it would also be possible to have a guiding means as a bar positioned through the center of the safety cones (not shown). All such variations are considered to be within the scope and spirit of the present invention as defined by the following claims and their legal equivalents.
