Referring now more specifically to Figure 1 of the drawings, reference numeral 10 designates, in general, a barricade constructed in accordance with the teachings of this invention. The barricade 10 is seen to include an outer, elongated, substantially hollow rectangular section 12 having a pair of opposed confronting open ends, a pair of longitudinally extending, substantially rectangular, laterally spaced and parallel side walls 14, 16, and a pair of longitudinally extending substantially rectangular, laterally spaced and parallel top and bottom walls 18, 26. An elongated, substantially rectangular slot 22 extends transversely through the bottom wall 20 throughout its length, the slot 22 being centrally spaced intermediate the side walls 14, 16 (see Figure 6).

Reference numeral 24 designates an elongated, substantially U-shaped tie member having a bight portion 26 from the longitudinally extending marginal edges of which upwardly project a pair of laterally spaced and substantially parallel side arms 28, 30, and each of the latter terminate in a pair of outwardly diverging anges 32, 34, respectively. The anges 32, 34 are welded to the bottom wall 20 adjacent one of its ends, and extends longitudinally thereagainst with the bight 26 extending for a limited distance inwardly across the slot 22 to leave the major portion thereof open.

A cylindrical hinge pin 36 extends between the sidewalls 14, 16 and its opposed ends project beyond the remote sides thereof at points spaced inwardly from the aforementioned one end of the outer section 12 and slightly above the longitudinal axis of each of the side walls 14, 16. The hinge pin 36 receives a substantially hollow cylindrical spacer member 3S which extends between the adjacent sides of the side walls 14, 16, the spacer member 38 being xedly secured to the hinge pin 36 by means of a cotter pin 40.

A lock pin 42 extends between the side walls 14, 16 and its opposed ends project beyond the remote sides thereof, the lock pin 42 being disposed intermediate the aforementioned one end of the outer section 12 and the hinge pin 36 and being vertically spaced higher than the latter. A substantially hollow cylindrical spacer member 44 is telescoped over the lock pin 42, the spacer member 44 extending between the adjacent sides of the side walls 14, 16 and being connected thereto by means of a cotter pin 46.

Each of the projecting ends of the hinge pin 36 ,arej

threaded and pivotally receive thereon one end, respectively, of' a pair of identically constructed elongated and substantially rectangular hinge plates 48, the plates 48 being held against displacement by means of lock nuts Sti. To serve a function to be described, each `of the plates -48 is provided with an arcuate slot 52 which extends inwardly from its upper edge and is positioned adjacent the other end thereof.

Reference numeral S4 connotes, in general, a substan tially U-shaped hinge bracket which includes a bight portion 56 from the longitudinally extending marginal edges of which depend a pair of laterally spaced and substantially parallel side arms 58, 60 which terminate atv their respective outer ends in diverging ilanges 62, 64. As is best seen in Figures 6 and 8, the bight portion 56 is angularly inclined with respect to the ilanges 62, 64.

A hinge bracket 54 is secured to each of the hinge plates 48 with the anges 62, 64 being juxtaposed thereagainst intermediate the ends thereof and being rigidly secured thereto as by welding. As is seen in Figures l and 2, the ilanges 62, 64 extend transversely across their respective associated hinge plates 48. A hinge leg for each of the hingebrackets 54 is generally indicated at 66 and is seen to comprise an elongated substantially hollow cylindrical member 68 having a closure Wall 78 extending across one end thereof and from which projects a tongue 72 extending diametrically thereacross. Each of the tongues 72 are received within one of the hinge brackets 54, respectively, and are pivotally connected on the side walls S8, 60 on pivot pins 74.

Reference numerals 76 denote a pair of identical standards or legs which have an elongated substantially hollow cylindrical conguration. rl`he upper ends of the standards 76 are telescoped within the cylindrical mem ber 68 and are retained therein by lock pins 78. One of the standards 76 is provided with a radially projecting headed stud 80 adjacent the upper end thereof, and a similar headed stud 82 projects radially from the other of the standards 76 adjacent its lower end. To the former is pivotally secured at 84 one end of an elongated substantially rectangular lever 86 having a slot 8S adjacent one end thereof and a second slot 90 spaced inwardly from the slot 88. As is seen in Figure 1, With the standards 76 disposed in their operative position, the lever 86 is pivoted to extend thereacross with the stud 82 engaged within the slot 88, the lever 86 in this case Iacting as a cross brace to prevent movement of the standards 76 relative to each other. When the standards 76 are moved to their inoperative position, as shown in Figure 2, the levers 86 are pivoted thereagainst and extend longitudinally thereof With the stud 80 being received Within the slot f90 and thereby limiting the pivotal movement of the levers 86 in one direction.

Intermediate the ends of the side walls 14, 16 are secured outwardly opening vconvoluted resilient support clips 92 each of which include a bight portion 94 from the ends of which project a pair of curvilinear arms 96, 98, the outer end of the latter being integrally connected with the outer end of a third curvilinear arm 100, connected by a bight 102 to a fourth curvilinear arm 104. The bights 94, 182 of each of the clips 92 are welded to the side walls 14, 16.

The other ends of the side Walls 14, 16 are each slotted at 106 and cut out at 108 to serve a function to be described. The bottom wall 20, adjacent the other end of the outer member 12 is provided with a stop clamp 118. The stop clamp 110 comprises an elongated substantially U-shaped channel member having a centrally positioned bight portion 112 (see Figures 4 and 5) from which project a pair of laterally spaced and substantially parallel side arms 1114, 116 which terminate in outwardly diverging flanges 118, 128 that extend longitudinally or' the bottom wall 20 on each side of the slot 22 and are secured thereto as by welding. The bight portion -112 terminates .at y.one of `its ends in `a clownwardly curved cam element 122 and at its other end in an upwardly curved abutment 124.

The barricade 18 also includes a central, elongated, substantially hollow rectangular section 126 having a pair of opposed confronting open ends, a pair of longitudinally extending, substantially rectangular, laterally spaced and parallel side walls 128, 138, and a pair of longitudinally extending substantially rectangular, laterally spaced and y parallel top and bottom walls 132, 134. An elongated,

substantially rectangular slot 136 extends transversely through the bottom wall 134 throughout its length, the slot being centrally spaced intermediate the side walls 128, (see Figure 7). The bottom wall 134, adjacent each end thereof, is provided with downwardly or outwardly expressed offset ends 138, 140.

Reference numeral 142 denotes an elongated substantially T-shaped clamp bar having a stem 144 (see Figures 4 and 6) and a crosshead 146. The crosshead 146 is i'ixedly secured to the oiset bottom Wall portion 138 with the stem thereof projecting downwardly through the slots 136 and 22, in that order, to serve a function to be described.

The side walls 128, 139 adjacent that end of the central section 126 carrying the clamp bar 142 is formed with an inwardly extending elongated slot 148 aligned with and having a width slightly greater than the outside diameter of the spacer member 38 and a cutout portion 150 having a width slightly greater than the outside diameter of the spacer member 44. The other end of the side walls 12S, 130 are provided with elongated slots 152 and cutouts 154, and the expressed portion of the bottom wall 136 has secured thereto the crosshead 156 of an inverted substantially T-shaped clamp bar 158 having a longitudinally extending stem 160 projecting inwardly within the central section 126.

The inner section of the barricade 18 is designated at 162 and is seen to include an elongated, substantially hollow rectangular member having a pair of opposed confronting open ends, a pair of longitudinally extending substantially rectangular, laterally spaced and parallel side walls 164, 166, and a pair of longitudinally extending substantially rectangular, laterally spaced and parallel top and bottom walls 168, 170. An elongated, substantially rectangular slot 172 extends transversely through the bottom wall throughout its length, the slot 22 being centrally spaced intermediate the side walls 164, 166 (see Figure 7). The bottom wall 170, adjacent the outer end of the inner member 162 is provided with a stop clamp 174 similar to the stop clamp 110, but inverted with respect thereto. The stop clamp 174 comprises an elongated substantially U-shaped channel member having a centrally positioned bight portion 176 from which projects a pair of laterally spaced and substantially parallel side arms 178, 180. The side arms 178, 180 are secured to the adjacent sides of the side walls 164, 166 by conventional means such as, for example, welding. The bight portion 176 at its outer end terminates in a downwardly curved abutment 182, and the other end thereof terminates in an upwardly curved cam element 184.

The other end of the inner section 162 of the barricade 10 is provided with an inner tie member 186, the tie comprising an elongated substantially U-shaped channel member having a bight 188 from the longitudinally extending marginal edges of which project a pair of laterally spaced and substantially parallel side arms 190, 192, the latter being lixedly secured to the adjacent inner sides of the side walls 164, 166.

To serve a function to be described, the inner ends of the side walls 164, 166 are provided with elongated slots 194 and cutouts 196, the slots 194 being in longitudinal alignment with the slots 48 formed in the side walls 128, 130, and the cutouts 196 being aligned with the cutouts 150 formed in the side walls 128, 130 of the central section 126.

A cylindrical hinge pin 200 extends between the side walls 164, 166 and its opposed ends project beyond the remote sides thereof at points spaced inwardly from the outer end of the inner section 162 and below the longitudinal axis of each one thereof. A substantially hollow cylindrical spacer member 202 is telescoped over the hinge pin 200 and extends between the adjacent sides of the side walls 164, 166, the spacer member being pivotally secured to the hinge pin 200 by means of a cotter pin 204. Between the outer ends of the inner sections 162 and the hinge pin 200 and vertically spaced thereabove is a lock pin 206 which extends between the side walls 164, 166 and projects beyond the remote sides thereof. A substantially hollow cylindrical spacer member 208 is telescoped over the lock pin 206 and extends between the adjacent sides of the side walls 164,166 and is connected to the lock pin 206 by means of a cotter pin 210.

One end of a pair of hinge plates 212 is pivotally connected, respectively, on the outer ends of the hinge pin 200 and is held against displacement by means of the lock nuts 214. The other ends of the hinge plates 212 are each provided with an arcuate slot 216, the function of which will be set forth below.

Reference numeral 218 connotes, in general, a substantially U-shaped hinge bracket which includes a bight portion 220 from the longitudinally extending marginal edges of which extend a pair of laterally spaced and substantially parallel side arms 222, 224 which terminate at their respective outer ends in diverging flanges 226, 228, respectively. As is best seen in Figure 7, the bight portion 220 is angularly inclined with respect to the anges 226, 228.

A hinge bracket 218 is secured to each of the hinge plates 212 with the flanges 226, 228 being juxtaposed thereagainst intermediate the ends thereof and being rigidly secured thereto as by welding. As seen in Figures 4 and 7, the flanges 226, 228 extend transversely across their respective associated hinge plates 212.

A hinge leg for each of the hinge brackets 218 is generally indicated at 230 and is seen to comprise an elongated substantially hollow cylindrical member 232 having a closure wall 234 extending across one end thereof and from which projects a tongue 236 extending substantially diametrically thereacross. Each of the tongues 236 is received within one of the hinge brackets 218, respectively, and is pivotally connected on the side walls 222, 224 on pivot pins 238.

Reference numerals 240 denote a pair of identical standards or legs which have an elongated substantially hollow cylindrical configuration. The upper ends of the standards 240 are telescoped within the cylindrical members 230 and are retained therein by lock pins 242.

One of the standards 240 is provided with a radially projecting headed stud 243 adjacent the upper end thereof, and a similar headed stud 244 projects radially from the other of the standards 240 adjacent its lower end.

To the former is pivotally secured one end of an elongated substantially rectangular lever 246 having the same configuration as the lever 86 previously described. The lever 246 has formed therein adjacent the other end thereof a slot (not shown) to receive the stud 244 in order to hold the standards 240 against movement relative to each other.

Having described and illustrated one embodiment of this invention in detail, its operation is deemed to be manifest. However, a brief description thereof is set forth below.

Let it be assumed that the barricade is in its extended position as is illustrated in Figure l, the operator pushes the inner section 162 inwardly towards the central section 126 causing stop clamp 174 to become disengaged from the clamp bar 160, and as this movement takes place the outer ends of the lock pin 206 enters the cutouts 154 and the outer ends of the hinge pin 200 enter the slots 152 thereby limiting the extent of the inner section 162 into the central section 126. At this point, the slots 148, 194 and cutouts '150, 196 are juxtaposed in side-by-side relation.

The inner section 162 and the central section 126 are then pushed into the outer section 12 causing the clamp oar 142 to disengage the stop clamp 110. As this movement is continued, the outer ends of the lock pin 206 is received within the cutouts 108 and the outer ends of the hinge pin 200 enter the slots 106. Substantially simultaneously therewith, the juxtaposed slots 148, 194 and cutouts 150, 196 receive the outer ends of the hinge pin 36 and lock pin 42, respectively. Thus, the barricade 10 is collapsed with the component elements thereof assuming their respective positions as is illustrated in Figure 2. The levers 86 and 246 are now disengaged from the studs 82 and 244 and are pivoted to axial extension with respect to the standards 76 and 240 on which they are pivotally connected with the stud being received within the slot 90 of the lever 86 and the stud 243 being received within a similar slot (not shown) in the lever 246. The standards 76 and 240 are now pivoted inwardly towards each other on each side of the barricade 10 for reception within the brackets 92 as illustrated in Figure 2.

To effect extension of the barricade the above procedural steps are carried out, substantially, in reverse. That is, the standards 76 and 240 are released from the brackets 92 and pivoted in the opposite direction in such a manner as to cause the opposite ends of the lock pins 42, 206 to enter the recesses 52, 216 formed in the hinge plates 48 and 212, respectively. With the standards 76, 240 so extended, the levers 86, 246 are pivoted to their operative position as shown in Figure 1, the levers receiving the studs 82 and 244, respectively.

The inner section 162 is now drawn outwardly of the central section 126 to effect re-engagement of the stop clamp 176 with the clamp bar 142. Relative movement between the inner section 162 and the outer section 126 ceases upon engagement of the downwardly curved portion 182 of the stop clamp 174 with the inner end of the clamp bar 142. Continued movement of the inner section 162 causes the central section 126 toslide outwardly of the outer section 12. The relative movement between the outer section 12 and the central section 126 is limited upon the re-engagement of the outer end of the clamp bar 142 with the upwardly turned end portion 124 of the stop clamp 110. The component elements of the barricade 10 have now assumed their respective positions as is illustrated in Figures 1 and 4.

Having described and illustrated one embodiment of this invention in detail, it will be understood that the same is offered merely by way of example, and that this invention is to be limited only by the scope of the appended claims.
