Also, construction involving a roadway will often require that traffic be rerouted to another highway or to unaffected portions of the highway under consturction.

To re-route the traffic around the construction site or to prevent traffic passing in close proximity thereto from driving off the usable portion of the road to the detriment of either the driver or those working on the road, it is often necessary to set up barricades which serve to channel the traffic away from the hazardous area. Since several miles of highway will often be under construction, it is a fairly large task to erect the necessary number of barricades. One of the chief problems is the fact that each of the barricades must be large enough to be seen by the motorist as well as heavy enough to safely slow down or stop a vehicle which fails to avoid the barricade. Another problem is the fact that a barricade of sufficient mass to stop a moving vehicle is quite difficult to transport to the construction site as well as position or reposition it once it is on the job. In fact, the latter often requires the use of a crane which is both time consuming and expensive to operate. Another difficulty with most barricades is that they are difficult to transport and store in bulk due to their size and shape.

OBJECTS OF THE INVENTION It is therefore, an object of this invention to provide a roadway barrier including a lightweight, hollow base member which may be filled with liquid to render it extremely massive or emptied to permit it to be easily positioned and transported.

Another object of this invention is to provide a roadway barrier of sturdy construction, yet requiring a relatively minimal amount of material for its manufacture.

A further object of this invention is to provide a roadway barrier which may be rapidly disassembled to permit efficient storage and transportation in bulk.

A still further object of this invention is to provide a roadway barrier which may be readily and economically manufactured.

Yet another object of this invention is to provide a roadway barrier having a tamper-proof means for filling and evacuating the liquid reservoir.

A still further object of this invention is to provide a roadway barrier-which may be used in conjunction with a vertical barricade structure or, alternatively, as a portable curb.

An additional object of this invention is to provide a roadway barrier primarily made of a material other than wood thereby lessening ecological impact, decreasing maintenance requirements for the barrier and reducing the chances of injury should the barrier be struck by a vehicle.

SUMMARY OF THE INVENTION The barricade of the present invention is particularly adapted for use on roadways or the like and includes a substantially rigid base having a liquid reservoir therein and an attachment on the base for securing a barricade structure thereto. Means for permitting a liquid to be introduced into and evacuated from the reservoir as well as caps for sealing the reservoir are also provided.

FIGS. 1 THROUGH 5 The barrier includes a hollow, elongated, rectangular parallelipipedal base 10preferably made of an impact resistant sturdy plastic such as one of the polyolefins, i.e., polyethylene, polypropylene or an acrylonitrilebutadiene styrene resin of the class commonly known as an ABS resin.

The primary requirements of the base material are that it be impervious to liquid and sufficiently rigid and sturdy to maintain its shape when filled with water or other liquids or fluid-like material. As already mentioned, the base 10 is hollow so as to provide a reservoir 12 therein for the purpose of containing a liquid 13 such as water which will impart a degree of mass to base 10 depending on the level to which reservoir 12 is filled.

Base 10 is provided with a pair of

passageways

14 and 16 at one end 18 and identical passageways l6 and 18' at its other end 20 for the purpose of admitting water to reservoir 12 as well as emptying the same. Normally the reservoir 12 will be filled through passageway 14 and evacuated through passageway 16, the latter being achieved through gravity and requiring no pumping.

Each of the

passageways

14, 16 are sealed by means of

caps

22 and 24, respectively, which are threadedly secured to their respective passageways. In order to prevent the

caps

22 and 24 from being lost when they are removed, they are joined together by means of a nylon line 26 which is secured to their

bases

28, 30 by means of

swivels

32 and 34 which serve to prevent line twist when the

caps

22 and 24 are screwed or unscrewed. The

caps

22 and 24 are further-provided with a resilient washer 36 as illustrated in FIG. 4a. 7

It is preferable that the

caps

22 and 24 be peripherally enclosed by

recesses

38 and 40, respectively, when tightened and that the clearance between the heads 42 of the caps and the recess walls 44 (see FIG. 40) be sufficiently small to prevent one from inserting his fingers therein and removing the caps 22 and- 24. By these means,

caps

22 and 24 could be removed only by a special tool adapted to fit the

recesses

46 and 48, which may be hexagonal, octagonal, etc. Permitting .the

caps

22 and 24 to be removed only through the use ofa special tool renders the barricade relatively tamper-proof to children, etc., as well as theft proof, the latter due to the fact that the base is extremely heavy when filled with water and must normally be emptied before it is manually moved.

Caps 22' and 24', associated with passageways 14 and 18', are of similar construction and operation.

Each of the

ends

18 and 20 of base 10 are provided with

external recesses

50 and 52, respectively, which serve as hand holds to facilitate the manual carrying of the barrier.

The barrier may include a barricade structure 54 which comprises a pair of

vertical post members

56 and 28 secured to base 10 by means of frames 60 and. 62 and

lateral slats

64, 66 and 68 which may be nailed, bolted or otherwise fastened to

vertical posts

56 and 58. It should be noted that, while normal usage will dictate the use of unyielding material such as wood or steel in the barricade structure 54, it may often be desirable to employ a frangible or shock absorbing barricade to prevent serious injury should a motorist crash into the barricade.

Frames

60 and 62 include cooperating

members

70, 72, 74, 76 and 78, 80, 82, 84, respectively. As best illustrated in FIG. 5, member 70 fits into the

recesses

86 and 88 of

members

72 and 76, respectively, while member 74 fits into

recesses

90 and 92 in

members

72 and 76. Bolt 94, which passes through vertical post 56,

members

76, 70 and 72 and bolt 96 which passes through vertical post 56,

structural members

76, 74 and 72 serve to hold the

members

70, 72, 74 and 76 in a rigid assembly encircling base 10 in a lateral direction when

nuts

98 and 100 are tightened. Bolt and

nut assemblages

94, 98 and 96, 100 are also employed to draw the vertical post 56 against frame member 76. Bolt and

nut assemblages

102, 106 and 104, 108 cooperate with interfitting

frame members

78, 80, 82 and 84 to form the rigid frame 62 and draw vertical post 58 against member 84 in a similar manner. In order to prevent the barricade 54 and

frames

60 and 62 from shifting longitudinally on base 10,

frame members

76 and 74 are positioned in recesses 110 and 112 in base 10.

Members

84 and 82 of frame 62 are positioned in similar recesses in base 10 near its other end 20. It is preferable that

frame members

74 and 82 be provided with

longitudinal flanges

114 and 116, respectively, in order that the load on these members be distributed over a wider area if the filledbarrier is lifted by means of barricade structure 54. Also, it is preferable that there be clearances 1 18 and 120 between the walls of recess 112 and frame member 74 to permit vertical post 56 to be held against frame 60 by means of a strap or the like as will be described below. There should be similar clearances between member 82 and its corresponding recess to accomplish a similar purpose.

The device is utilized as follows:

' The barrier will normally be transported and stored with the base member empty of water and the barricade structure removed to facilitate manual handling and storage in bulk. The barricade 54 may be removed by first removing

nuts

98, 100, 106 and 108 and sliding the

vertical posts

56 and 58 off their

respective retaining bolts

94, 96, 102 and 104. The nuts 98, 100, 106 and 108 may then be screwed down on their

respective bolts

94, 96, 102 and '104until they abut

frame members

76 and 84. It should also be noted that the base 10 could be employed as a portable curb or the like, either with or without

frames

60 and 62 depending on the circumstances.

Once the barrier is placed in the desired location, cap 22 is removed and the reservoir 12 filled with water or another liquid until the base 10 has acquired sufficient mass to satisfy the requirements of the particular situation. Cap 22 is then replaced and tightened down on washer 36. Depending on the amount and size of equipment available, the barrier may be repositioned when full by the attachment of a crane hook or cable to barricade structure 54 and lifting it off the ground, or it may be emptied of water by removing cap 24 and then repositioning the barrier manually.

FIG. 6

Another manner in which the barrier of FIGS. 1 through 5 could be employed is illustrated in FIG. 6.

In this modification, the base 122 is identical to base 10 illustrated in FIGS. 1 through 5, but the

frames

124 and 126 have been rotated about the longitudinal axis of the base and the barricade structure has been removed. The modified position of the

frames

124 and 126 permits the

bolts

128, 130, 131 and 133 to point downwardly thereby permitting their being anchored in the ground, road, or parking lot surface.

It should be noted that the conversion of the barrier shown in FIGS. 1 through 5 to the barrier shown in FIG. 6 may be accomplished merely be removing the barricade structure 54, disassembling the

frames

60 and 62, rotating then 90 about base 10 and then reassembling the

frames

60 and 62. In this manner the barrier may be converted to a portable curb or the like having means for anchoring it to the road surface.

FIGS. 7 THROUGH 11 A second modification of the roadway barrier illustrated in FIGS. 1 through 5 involves the means'for attaching the barricade structure to the frame assembly. The barrier includes a base 132 and barricade structure 134 of the type employed in the road barrier of FIGS. 1 through 5. A frame assembly 136 including interfitting

members

138, 140, 142 and 144 is positioned around base 132 and held together by means of

bolts

146 and 148 in a manner similar to the

frames

60 and 62 shown in FIGS. 1 through 5. The head 150 of bolt 146 is countersunk in member 138 to permit the vertical post 152 to lie flush against member 140. Bolt 148 is countersunk in a similar manner. In order to prevent the frame and

barricade assembly

136, 134 from shifting longitudinally along base 10, frame and members and 142 are positioned in

recesses

154 and 156,

respectively. It should be noted that the other end of base 132 is also providedwith a frame and vertical post assembly similar to the one just described.

Instead of bolting the vertical post l52 tothe frame 136, the barrier is providedswith:apair of retaining straps 158 and 160which are secured to frame

member

138 and 142, respectively. Strap 158. has a first U shaped portion 162 bordering three sides of member, 138 and secured thereto by means of

bolts

164 and 166 passingthroughmember-188-and retained by means of nuts (not shown) on the opposite side thereof as well as bolt 146 which passesthrou gharear hole 168 in strap portion 166. Strap 158 further includes a second U-shaped portion 170 which extends beyond frame 136 so as to receive the verticalipost 152 of barricade structure 134. The second U-shapedportion 17 is connected to the first .U-shaped portion 162 by means of a pair of

flexible hinges

172 and 174,

Retaining strap 160 includes a first U-shaped portion 176 positioned'in the gap between frame member 142 and the

walls

180 and 182 of recess 156 and the gap between

members

142 and 144. The first portion 176 of strap 160 is retained in this position by means of the flange. 184 of member 142. Strap 160 further includes a second U-shaped portion 186 extending beyond frame 136 to enclose vertical post :152. The second portion 186 is connected to'thefirst portion 176 by means of a pair of

hinges

188 and 190.

It should be noted that a similar-retaining strap arrangement is employed to secure the other post (not shown) of barricade 13.4.v L V in a preferred design, the straps 8 and 160 are made ofa plastic having good elastic properties, i.e., after deformation, it will return to its undeformed state and shape and will continue to do so even after numerous deformations. Polypropylene is one such plastic having these characteristics. As previously mentioned, the

U-shaped portions

170 and 186 which encircle the barricade post 152 are connected to the first

U-shaped portions

162 and 176 by means of

hinges

172, 174 and 188, 190, respectively. in the preferred embodiment, each of the

hinges

172, 174, 188 and 190 comprise a section of the

straps

158 and 160 which has been creased or otherwise weakened along three lines such as 192, 194 and 196 which meet at a point 198 along three lines such as 192, 194 and 196 which meet at a point 198 along the upper edge 200 of each of the straps. In the undeformed state of the strap, the U- shaped

portions

170 and 186 extend at an angle from the first

U-shaped portions

162 and 166 and their leading

portions

202 and 204 engage the vertical post and draw it into abutment with the frame assembly 136. As best illustrated in FIGS. 9 and 10, if the second U- shaped portions of the retaining

straps

158 and 160 are pulled downwardly to the dotted line position, the creased or weakened sections of

straps

158 and 160, i.e., hinges 172, 174, 188 and 190 will bow outwardly (see FIG. 9) and there will be suffient clearance 206 between the leading

portions

202 and 204 and post 152 to permit it to slide within-

U-shaped portions

170 and 186. In this manner, easy attachment or removal of the barricade structure 134 from the base and

frame assembly

132, 136 may be achieved.

By making the base of a highly visible, permanently colored plastic material instead of sawn natural logs or other wood products, a two-fold advantage results: the need for periodic painting is eliminated and the consumption of large quantities of wood is reduced thereby providing a beneficial ecological effect.

it should be, noted that varioysymodifications of the preferred embodiments illustrated could be made without departingfrom the scopeof the invention. The base members could be made by" any'number of processes such as vacuum forming, pressure forming, etc, and the frame assembly couldfbe made of thesame material as the base thereby permittin'git to be formed integrally therewith in a single. operation. Also, the retaining straps of the embodiment illustrated in FIGS. 7 through 11 could be made integral with the frame assembly or with the frameassembly and base member. Y

The frame members could be made of polyethylene, polystyrene,'lwood, scrap lumber foundon the con struction site, 'etc.-, Typical dimensions for the base member are 12 inches by 112 inches by 8 feet.

While this invention has been described, as having a preferred design, it will be understood that it is capable of further modification. This ,application is, therefore, intendedto cover any variations, uses, or adaptations of the invention following the general principlesof the invention and including such departures from the present-disclosure as come within known or customary practice in the art to which this invention pertains and as may be applied to the essential features hereinbefore set forth and fall within the scope of this invention or the limits .of the appendedclaims.
