ROAD BARRICADE I Filed Feb. 12, 1954 2 Shets-Sheet 2 INVENTOR. 2 1 5 E/oen E. E///' oz2 United States Patent 1 2,701,127 ROAD BARRICADE Elden E. Elliott, Larned, Kans., assignor to Rubber Barricade Co. Inc., Larned, Kans., a corporation of Kansas Application February 12, 1954, Serial N 0. 409,891 3 Claims. (Cl. 256-64) This invention relates to road barricades.
It is well known that road barricades are subject to abuse and a high degree of destruction due to the impact of vehicles therewith. Further, due to the construction of existing road barricades, vehicles are generally damaged and passengers seated therein are sub ject to injury upon collision of the vehicles w1th the barricades.
Therefore, it is an object of this invention to provlde a road barricade which has resilient qualities and thereby substantally lengthens the life of the barricade and eliminates the danger of damage to vehicles or injury to passengers resulting from a collision by a vehicle with the barricade.
Other objects and advantages will become apparent from a consideration of the following description taken in view of the drawings, wherein:
Figure 1 is a side elevational view of a road barricade constructed according to the present invention;
Figure 2 is a top view, with parts broken away, of the barricade shown in Figure 1;
Figure 3 is an end view of the barricade of Figure 1;
Figure 4 is an enlarged transverse sectional view of the cross bar of the barricade taken along line 4-4 of Figure 1;
Figure 5 is a fragmentary elevational view of the cross bar of the barricade taken along line 55 of Figure 4;
Figure 6 is an enlarged cross sectional view taken along line 6-6 of Figure 3; and
Figure 7 is an enlarged view taken along line 7--7 of Figure 3 with the brace of the upright shown in cross section and showing the lower end portion of the adjacent leg of the upright.
Referring now to the drawings in more detail, wherein like reference numerals are used throughout, a road barricade constructed according to the present invention is indicated generally by the reference numeral 10.
It is intended that the barricade 10 be fabricated in its entirety, exclusive of the fastening means, of a flexible and resilient material, such as rubber or a plastic composition. From a practical viewpoint, it is contemplated that the barricade be constructed from reclaimed pneumatic rubber tires now in general use upon automotive vehicles.
The barricade 10 comprises spaced A-frame uprights 11 and 12 which are identical in structure and, hence, only upright 11 will be described. The upright 11 includes a pair of diverging legs 13 and 14, as shown in Figure 3, and a brace 16 which extends between and connects the legs 13 and 14 adjacent the lower ends thereof. The upper converging ends of the legs 13 and 14 are formed into opposed parallel panels 20 and 21. In a like manner, opposed parallel panels 22 and 23 are formed at the upper converging ends of the legs 25 and 26 of the upright 12. Extending transversely through the panels 20 and 21 is a fastener or bolt 27, and extending through panels 22 and 23 is a similar bolt 28. The bolts 27 and 28 connect the opposed panels 20, 21 and 22, 23, respectively. Loosely carried by the bolts 27 and 28 are flexible and resilient spacer blocks 29, as shown in Figure 3, which maintain the panels 20, 21 and 22, 23 in a spaced apart relation.
As shown in Figures 1 and 2, a cross bar 31 extends between the uprights 11 and 12 and is removably positioned between the panels 20, 21 and 22, 23. The cross bar 31 is supported by the spacer blocks 29, as seen in Figure 3. Each pair of panels 20, 21 and 22, 23, together with the corresponding bolts 27, 28 and spacer blocks 29, constitute a supporting means for the cross bar 31.
Since the detailed construction of the uprights 11 and 12 is identical throughout, only the leg 14 of the upright 11 will be described. As shown in Figure 6, the leg 14 embodies opposed laminated walls 32 and 33 connected 2,701,127 Patented Feb. 1, 1955 at spaced intervals by rivets 34 extending between the walls 32 and 33. The walls 32 and 33 have flexible outer layers 36 and 37, respectively and resilient inner layers 38 and 39. A reinforcing means 41, extending longitudinally of the walls 32 and 33, is positioned between and spaces apart the walls 32 and 33 of the leg 14. As shown in Figure 6, the reinforcing means 41 is laminated and embodies a flexible layer 42 and a resilient layer 43.
When re-claimed pneumatic rubber tires are used in constructing the barricade 10, the cord carcass of the tire would correspond to the flexible layers 36, 37, 42, and the tread would correspond to the resilient layers 38, 39, 43.
The brace 16 differs from the construction of the balance of the upright 11 in that it carries flanges 17 at the ends thereof for connection to the adjacent legs 13 and 14, as shown in Figure 3.
As seen in Figure 4, the cross bar 31 embodies opposed laminated walls 45 and 46 which are connected at spaced intervals therealong by rivets 34 which extend therethrough. The walls 45 and 46 have flexible outer layers 47 and 48, and flexible inner layers 49 and 50, respectively. Extending longitudinally through the cross bar 31 between the walls 45 and 46 is a reinforcing means 52 of a flexible nature.
As shown in Figure 5, the rivets 34 are arranged in a row adjacent each of the side edges 53 and 54 of the cross bar 31. Located intermediate the side edges 53, 54 are two parallel rows of rivets 34 in which the rivets of each row are spaced between the rivets of the other row. Positioned between the two rows of rivets 34 which are arranged intermediate the side edges 53, 54, and between the walls 45, 46 is a stiffening means in the form of a pan of wires 56, 57 which extend longitudinally of the walls 45, 46. The wires 56 and 57 serve to strengthen and rigidify the cross bar 31.
Fixedly secured to the outer surface of the walls 45, 46 intermediate the ends thereof by rivets 34 are bumpers 58 and 59 which project laterally from the cross bar 31 and are preferably fabricated of a resilient material.
Due to the resilient quality of the barricade 10, the rivets 34 compress the layers of the walls to that the rivet heads are positioned below the surface of the surrounding wall portions. In this way, the rivets are protected from damage.
It is to be noted that the uprights 11 and 12 may be constructed in a manner similar to that of the cross bar 31, particularly with reference to providing the uprights 11 and 12 with stiffening means, such as the wires 56 and 57 of the cross bar 31.
What is claimed is:
1. A road barricade comprising spaced uprights having support means at the upper ends thereof, and a cross bar extending between and removably mounted on said supporting means, said uprights and said bar including opposed .walls connected at spaced intervals therealong, and a pair of resilient bodies arranged in side by side relation extending longitudinally of and interposed between said walls.
2. A road barricade comprising spaced uprights having support means at the upper ends thereof, and a cross bar extending between and removably mounted on said supporting means, said uprights and said bar including opposed walls connected at spaced intervals therealong, a pan of resilient bodies arranged in side by side relation extending longitudinally of and interposed between said walls, and reinforcing means positioned between and spacing apart said resilient bodies.
3. A road barricade comprising spaced uprights having support means at the upper ends thereof, and a cross bar extending between and removably mounted on said supporting means, said cross bar including opposed walls connected at spaced intervals therealong, a body of resilient material extending longitudinally of and interposed between said walls, and stiffening means extending longitudinally of said walls and positioned between said body and at least one of said walls.
