Description




FIELD OF THE INVENTION




The invention relates to a child's safety barrier and especially a barrier for positioning near an end of the driveway or other inclined surface for preventing rolling objects such as balls from passing the barrier.




BACKGROUND OF THE INVENTION




Children's safety is a major concern of parents, caretakers, and other adults. Most adults know of an occurrence when a child has run after a ball rolling into the street where and has not looked out for possible oncoming traffic. Tragically, some children have been injured or killed by a vehicle when they ran into the street to retrieve the ball. Parents in the past have provided a makeshift barrier at the end of their driveway out of furniture, blocks of wood, and other articles to prevent their children's play toys from rolling into the street and thereby preventing the children from retrieving the play toys. These previous barriers used by parents to block rolling objects were generally cumbersome to move, unattractive and did not always stop the rolling object. In addition, the articles had to be removed from a driveway before a vehicle could proceed into the homeowner's yard.




SUMMARY OF THE INVENTION




It is the intent of the current invention to address the aforementioned concerns by providing a barrier for rolling objects and especially for children's balls and other rolling playthings that is lightweight to carry, transportable, durable, easily connectable to each other to adjust its length, as well as easy and inexpensive to manufacture. The safety barrier of the present invention is an elongated member having a base and a first and second wall extending upwardly from the base. The first and second walls meet at an upper point spaced above the base wherein at least one of the walls has a concave exterior surface.




In another aspect of the invention the concave exterior surface may include a first ramp extending from the base to an innermost point and a second ramp extending from the innermost point to the upper point.




In yet another aspect of the invention, the base may include means for allowing liquids to drain past the barrier.




In another aspect of the invention, there is a means of releasably securing one barrier to an adjacent barrier.




Other objects, advantages and applications of the present invention will become apparent to those skilled in the art when the following description of the best mode contemplated for practicing the invention is read in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT




The present invention provides a bumper style safety barrier for placement near or at the end of a driveway


5


or other incline surfaces where children are likely to play. The safety barrier is provided and designed to deter run-away balls, tricycles, baby carriages and other rolling objects from passing the safety barrier and rolling into the street and into potential oncoming traffic.




The safety barrier


10


of the present invention includes an elongated structure for placement laterally across a driveway


5


to define a safe play area


11


for children. The safety barrier


10


is preferably configured such that a ball or other rolling device used by a child is deterred from jumping over and passing the safety barrier


10


and continuing into a dangerous area, such as a street


13


.




Looking at

FIG. 3

, the safety barrier


10


is structured to have a wider (W) base


12


than height (H). Currently, the height (H) from the base


12


to the highest point


14


of the safety barrier


10


is approximately four inches. The depth or width (W) of the base


12


is approximately eight inches. The length (L) of the safety barrier structure


10


can vary, but preferably has a length to extend over the driveway in four or five feet sections. The length (L) of the safety barrier


10


is kept to a reasonable length so that it can be easily transported and positioned manually to its designated location. The weight is also kept to less than ten pounds and preferably from four to six pounds.




The preferred embodiment is shown in

FIG. 2

, wherein a connecting lock


40


is provided for placement between adjacent safety barriers


10


. The connecting lock


40


has a general cross configuration with two of the opposing cross members forming a pair of spring loaded tines


42


. The safety barrier


10


is modified to receive one of the pair of spring loaded tines


42


in each of the lateral ends. Each lateral end of the safety barrier


10


will have a keyhole


31


formed in the base


12


. The keyhole


31


is shown in

FIG. 5



e


. The pair of tines


42


are pushed together and inserted into keyhole


31


. Upon release of the tines, the peripheral edge


33


of the keyhole


31


is held within the outer grooves


43


of the tines


42


. The other two cross members


44


located approximately 90° relative to the tines


42


form a spacer between adjacent safety barriers. The spacing between adjacent safety barriers is the length of side


46


of cross members


44


.




In another embodiment as shown in

FIGS. 3 and 4

, the base


12


is an essentially flat surface for positioning on a driveway


5


or other relatively smooth surface. The base


12


may include grooves or channels


15


extending the entire depth (W) of the base


12


to provide water drainage. The grooves


15


are spaced approximately every twelve inches along the length (L) of the safety barrier


10


, and allows water that collects in the driveway


5


to drain to the street.




The highest point


14


of the safety barrier structure


10


is positioned slightly offset from the center of the base


12


. The location of highest point


14


prevents the safety barrier


10


from being tipped over when rolling devices and toys roll into the safety barrier. The first elongated side


16


of the lateral length of the safety barrier


10


is concaved and preferred to have a triangular


18


recess along the entire length (L) for purposes discussed hereinafter. The top edge


20


of the triangular recess


18


should extend at least partially back toward the play area


11


. The first elongated side


16


is configured so that one portions the safety barrier


10


to face the interior of the play area


11


.




The barrier has a second elongated surface


22


that preferably meets the first side


16


at the top edge


20


. Although both elongated surfaces


16


,


22


may be configured to include the triangular recess


18


along each entire elongated surface, it is preferred and shown in the drawings that the second elongated surface


22


has a ramp formation to increase the structural stability of the overall safety barrier


10


and to easily allow a vehicle to ride over the safety barrier


10


without damage to the barrier


10


.




As shown in

FIGS. 1-4

,


5




a


,


5




d


,


5




e


and


5




f


the cross-sectional configuration of the safety barrier


10


reflects a cresting wave. The width (W) of the base


12


of the safety barrier


10


has a dimension approximately twice the height (H) of the safety barrier. This helps to maintain the center of gravity near the base


12


to prevent the safety barrier


10


from easily tipping in one direction or another. As seen in

FIG. 3

, the first elongated surface


16


has a first ramp


17


extending from the flat base surface and continuing to an innermost point


21


of the triangular recess


18


. The first elongated surface


16


then ramps


19


back to terminate at a top edge or forward point


20


of the crest. Each ramp


17


,


19


of the first elongated surface


16


may be either linear or arcuate as shown in the figures. The triangular or concave recess


18


provides advantages over other configurations as will be discussed hereinafter. The safety barrier


10


further includes a second elongated surface


22


forming the rearward edge of the wave configuration. The second elongated surface


22


has a second ramp


23


with a shallow S-curve formation terminating at the forward point


20


of the crest.




The forward point or top edge


20


of the crest helps to resist rolling balls from jumping over the top edge or crest of the barrier. The forward point


20


of the crest will act as a stop for the ball. The second ramp


23


is provided with a shallow S-curve formation to provide more mass near the base


12


of the barrier and to follow the line of the arcuate or triangular recess of the first elongated surface


16


to provide more material at the crest. Therefore, the crest portion of the safety barrier provides a collapsible but durable ramp for a vehicle's wheels when encountering the barrier from the second elongated surface side


22


. If a vehicle encounters the barrier from the first elongated surface side


16


, the crest portion will again collapse under the weight of the vehicles wheels. Testing has indicated that the configuration with the triangular recess


19


shows repeatability to collapse and then spring back to its original shape.




When more than one barrier


10


is used to extend over a driveway, a keyway is provided to align and secure one barrier


10


adjacent to another barrier


10


. One embodiment is shown in

FIG. 2

wherein the keyway includes a keyhole


30


in one lateral end


32


and a complementary key


34


in the other lateral end


36


. The keyhole


30


includes a groove or recess in the surface of lateral end


32


. The key


34


includes a nodule having a complementary configuration in the other lateral end. When two or more barriers are placed adjacent to each other, the key


34


of one barrier fits into the keyhole


30


of the adjacent barrier to releasably secure the barriers together.




The child safety barrier


10


of the present invention is preferably made of a semi-rigid material that is lightweight, flexible, and weather impervious. The material must allow the crest portion of the barrier to collapse under predetermined weight, such as that of a vehicle's wheels, but then spring back to its original shape. The material must also be able to withstand a predetermined number of drive-overs by a vehicle. Such material that is being considered and tested is rubber, polyurethane and foam. The child safety barrier


10


may also be manufactured of a composite of the aforementioned materials. Although the safety barrier


10


is preferably hollow, it is advantageous to provide an insert


26


(shown in

FIG. 4

) of rubber along the base


12


when the barrier is made of a polyurethane. The rubber insert adds weight to the base


12


to prevent the barrier


10


from tipping over. The rubber insert further adds mass along the base to increase durability.




The safety barrier is configured so that the recessed surface is positioned toward the play area


11


. If a ball rolls toward the barrier, the arcuate recess, and especially ramp


19


directs the ball back into the play area


11


. If the ball is larger than the arcuate recess, the forward point


20


stops the ball from further rolling. The upper or outer arcuate surface


22


will temporarily collapse under the weight of a vehicle or other heavy objects, but will spring back to its previous shape when the weight is removed.




Although the preferred embodiments are shown in

FIGS. 1-4

, other configurations for the safety barrier


10


are envisioned. In

FIG. 5



a


, the first elongated side


16


includes a first planar surface


117


that is generally horizontal and parallel to the base


112


. The first planar surface


117


terminates at an innermost point


121


. The first elongated surface


116


then has an arcuate ramp


119


to forward point


120


. A hinge


123


is provided along the length (L) of the safety barrier


10


at the innermost point


121


. If a vehicle drives over the safety barrier


10


, the tire of the vehicle will travel over outer arcuate surface


122


. The weight of the tires will move the outer arcuate surface


122


and arcuate ramp


119


toward the base


112


by pivoting at hinge


123


. Once the weight is removed, the hinge biases the outer arcuate surface


122


away from base


112


.





FIG. 5



b


shows another embodiment having a right angle configuration. The first planar surface


217


is also horizontal and parallel to base


212


and terminates at innermost point


221


. Ramp


219


is vertical and at a right angle relative to first planar surface


217


.





FIG. 5



c


show yet another embodiment which forms a pair of recesses


316




a


,


316




b


so that the safety barrier can be positioned having either recess


316




a


,


316




b


facing the play area. The center vertical portion


319


is flexible and can bend with the weight of tires and other heavy objects.





FIG. 5



d


shows an embodiment having a similar configuration as shown in

FIGS. 1-4

. In this embodiment, the lower portion forming the base


412


may be made of a solid rubber material or a plastic material having a hollow interior which can be filled with liquid, sand, or other material through an insert cap


421


to add weight to the base


412


. The upper portion


419


is a hollow inflatable material that can be partially filled with air. When a tire travels over the upper portion


419


, the air temporarily redistributes within the upper portion


419


until the weight is removed.





FIG. 5



e


shows an embodiment having a notch


523


along the outer, lower surface


521


. The outer surface


521


terminates at crest


520


. An undercrest


519


continues from crest


520


and terminates at roller


524


which extends the length of the barrier. The base


512


continues to a first elongate surface


516


having a first ramp


517


that terminates along an edge


518


. The barrier in

FIG. 5



e


is configured such that the roller


524


rests on the first elongate surface


516


. If a predetermined weight, such a vehicle tire rolls over the barrier, the outer surface


521


will bend along notch


523


and roller


524


will roll down first ramp


517


as the outer surface


521


bends. Once the weight is removed, the barrier will return to the original configuration as shown in

FIG. 5



e


. The notch may be replaced with any means of thinning of the material along the outer surface


516


to provide a bending location for the barrier.





FIG. 5



f


shows another embodiment with a thick base


612


and a narrow upper portion formed by the outer ramp


622


and inner ramp


615


.
