BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a system for erecting barricades in a jiffy as appropriate to the on-site situation. A number of different components are employed in this system. 
     2. Description of the Prior Art 
     There are many different types of barricade devices, and traffic warning devices known in the prior art. None of these known prior art devices, however, offers the versatility, flexibility, and ability to quickly adapt the component parts into an appropriate barricade for the situation. Some known prior art barricades are taught in the patents to Fairbairn, U.S. Pat. No. 1,457,900; Adams, U.S. Pat. No. 1,794,434; Stringer, U.S. Pat. No. 2,392,011; and Simpson, U.S. Pat. No. 3,057,601. The U.S. Pat. to Tingley, No. 1,275,795 shows somewhat related structure as adapted to fencing. And the U.S. Pats. to Underwood, No. 2,583,244 and Moinicken et al, No. 3,380,429 teach traffic warning signal lights which may be pertinent to this invention. None of these patented devices has the features of the component system disclosed by this invention. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a barricade system which is erectable in a jiffy. 
     Another object of the present invention is to provide various component parts for a barricade system which are flexible and adaptable in their use. 
     Another object of this invention is to provide barricade structures which include warning light/reflector devices. 
     There has always been a problem with barricades as taught in the prior art in being able to adapt same for different on-site situations, and/or problems which differ from the most common type problems. With the system and components therefor disclosed by this invention the drawbacks of prior art devices are eliminated. The system of this invention allows for flexible adaptation to any given on-site problem. Warning signs and signals, etc. are readily arranged with the components of this system to adequately warn a passing motorist or pedestrian of eminent danger. This is extremely important in today&#39;s high speed motor vehicle traffic. And also with the tremendous increase in pedestrian, bicycle, and motorcycle type traffic.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to the drawings one embodiment of the barricade system is shown by reference numeral 10 in FIG. 1. Reference numeral 12 indicates another barricade warning structure in FIG. 9. In both these figures reference numeral 14 refers to a base pan unit having a supporting cone structure 16 mounted thereon. FIGS. 2 and 14 show the base unit with cone structure in perspective view. The cone of FIG. 2 has a square socket 18 for receiving a square support post 20. FIG. 14 shows a round socket 18&#39; for receiving a round support post 20&#39;. In all of the modifications disclosed either square or round sockets and posts may be utilized, however, in most instances the square type is to be preferred. The reason being that the square type offers more rigidity and resistance to twisting under windy load conditions. 
     FIG. 3 shows a head unit having double slotted portions 24 therein. The stem post for allowing assembly of the head unit with other components of the barricade system is shown by reference numeral 26. FIG. 4 shows a modified embodiment of a head unit wherein the slotted portions 24&#39; are open at the top as indicated by reference numeral 28. The stem post 26&#39; is also of different construction in that it has a center hollow portion of square or round shape for receiving a support post 20 which is different from the stem post 26 of FIG. 3 which must be used with an adapter unit. 
     FIG. 5 shows a universal adapter for attaching warning signs to a cross tie device. Reference numeral 32 as shown in FIG. 1, refers to such a cross tie, as does reference numeral 34 indicating a cross tie having warning indicia thereon. The universal adapter of FIG. 5 labeled 36 has slots 38 and 39 therein of different widths. This adapter is used as shown in FIG. 1 to mount warning signs on or from cross tie members 32, 34. Such signs as indicated by the SLOW sign in FIG. 1 and the DANGER sign in the same figure are held in place by means of pins 40. Pins 40 are preferably made of plastic or rubber composition. Being made of such a composition they will be frictionally retained in the respective holes 30 of the various support and barricade device members to firmly lock such members together. 
     FIG. 6 shows a cross-sectional view of the barricade system of FIG. 1. As can be seen in this view the closed type support head 22 with slots 24 therein is mounted on the top of support post 20 by means of support pin member 26 and retained as assembled by means of pin 40 through the aligned holes 30 in the respective members. As can be seen in this view and also the view of FIG. 7, the respective ends of the cross tie members 32 and 34 are supported within the head. Each end of the respective cross tie members has a recess portion 38 therein for the purpose of locking the ends in the support head member. The normal weight of the cross tie members will be sufficient to keep the members locked in the support head due to the recess. 
     FIG. 6 also shows one method of retaining the base pan unit 14 and the support cone unit 16 removably locked together. In this figure screw threads 44 are provided on the cone 16 for engagement with screws 42 coming up through the base pan unit 14. This type of connecting structure is reliable and yet quite convenient. Again it is noted that the support post 20 and the cone support socket 18 may be of either square or round configuration. FIG. 8 is a cross-sectional view of the universal adapter of FIG. 5 and is shown as in FIG. 1 being mounted on a cross tie 32 for supporting a warning sign 33 with pins 40 holding the units together. 
     The components of this disclosed barricade system, i.e. the base pans, the cone units, and the support posts may be utilized as shown in FIG. 9 to support large warning signs. FIG. 10 shows in a side elevational view how such large signs may be directly bolted to the support posts. The base units and cone member attachable thereto to form the complete base assembly are also usable to support other type warning devices such as shown in FIGS. 11, 12 and 13. The warning devices of FIGS. 11 and 12 are cone shaped barber pole type warning devices, while the one in FIG. 13 is a rectangular flat shaped barber pole marked warning device. All three of these figures show the square support post, however round posts may be used equally as well. But with a type as shown in FIG. 13 being flat, the square type support offers the obvious advantage of not permitting rotation of the sign. 
     FIG. 15 shows a round type universal adapter similar to the universal adapter of FIG. 5 and FIG. 8 and having holes 30 therein for receiving assembly pins 40. 
     Another feature of the disclosed barricade system is in the modification shown in FIGS. 16, 17 and 18. In this embodiment of the invention the double-slotted support head as shown in FIG. 3 is modified by providing flange support means at the top thereof for receiving an electrical flashing light device. Looking at FIGS. 16 and 17, the support head 22&#34; having double slots therein 24&#34; for holding the notched ends of cross tie members 32 is locked to support post 20 by means of pin 40 and post 26&#34;. The electrical flasher light device 60 is mounted at the top of the support head by means of the flange 61 and the recess formed thereby 62 at each side of the head. The bottom portion of the flasher light has an extending flange 63 which frictionally slides into the recesses 62 and is thereby frictionally retained therein. The support head 22&#34; may be formed of molded plastic or similar material. In such case the flanges and recesses would be formed at the head of the device as it is molded. The member also could be made of wood and the recesses formed by a wood-working operation. Another way of modifying the concept shown in FIG. 3 is to use the support head 22 having the double slots 24 and modifying it as shown in FIG. 18 to achieve the desired results as of FIG. 16. This can easily be done by adding a flanged member 64 to each side of the upper part of the support head 22. The flanges 64 are provided with holes 66 for receiving the screws 68 which fasten the flanges to the head by means of holes 69 predrilled therein. 
     FIG. 19 shows another adaptation of the base unit with cone mounted thereon for holding the support post 20. The recessed portion 15 of the base pan is designed to hold water, sand, dirt or rocks for added weight to prevent the support from tipping. Another component of the barricade system is a weight ring as shown in FIGS. 19 and 20. The recess 15 is the base pan and the weight ring are of approximately the same size so that the ring will easily fit inside the recess. The weight ring 70 as shown in FIG. 20, in perspective, is actually two identical half rings. Each half ring covers 180° in circumference and is formed with a recess 74 on one side thereof and a projection 72 on the opposite side. The rings are preferably made of heavy material, lead of course being one of the heaviest though also quite expensive. Concrete and materials of this nature are more likely substitutes. When the rings are being used to hold a base pan in place two rings are put into the recess 15 of the base pan so that their respective ends abut and then if more weight is desired another two half-rings are put in place over the first two with the joint openings being spaced 90° from the joint openings of the first pair and with the recess 74 of the upper rings fitting over the projections 72 of the lower rings. It can be seen that once so installed the added weight will not be easily displaced and will render the support practically untippable. 
     Another feature of the barricade system of this invention is the detachable hold-down brace sleeve assembly shown in FIGS. 21a, 21b and 22. This device consists of a sleeve member 82 having a hole 83 therein slightly larger than the support post 20 and of either rectangular or round shape to conform to the shape of the support post. Angle portions 84, 84&#39; extending from said sleeve member are attached to the brace and hold-down members 20&#39;. The members 84 in FIG. 21a are in the form of sockets for receiving the ends of support posts 20&#39;, and members 84&#39; in FIG. 21b are in the form of pins for reception within the ends of support posts 20&#39;. These are preferably at a 90° angle to each other to thereby form approximately a 45° angle with the support post when the brace is in place. Pins 86 are used to hold the brace assembly to the ground. Such brace assemblies would be necessary in areas of extremely high winds, such as in tornado or hurricane situations where it is important to warn of a bridge being out, etc. and also very important that the warning signs not be tipped over and/or destroyed. 
     A further embodiment of the barricade system is in the post extension adapter shown in FIGS. 23 and 24. This post extension adapter is used to attach two of the support posts 20 together in order to extend or increase their length. Said extender is shown as being square, however as mentioned above a round configuration may also be used. The adapter has holes therein spaced to correspond with the end holes of a standard support post 20 and the pins 40 as described before are insertable through the holes in the adapter and the support post 20 to be extended. FIG. 24, a cross-sectional vertical view best shows this. 
     FIG. 25 shows another modification of the base pan 14 and the cone unit 16. Herein the modified base pan is labeled 14&#39; and the modified cone 16&#39;. Instead of using threaded screws 42 to hold the two units together as shown in FIGS. 6 and 19, a projecting threaded stud 92 is shown on the lower portion of the cone 16&#39; which screws into a threaded hole 94 in the base pan unit 14&#39;. Still further modifications of components for the barricade system are shown in FIGS. 26 through 30. The cone unit in FIGS. 26, 27 is labeled 16&#34; and it has projecting flanges 96 at the lower end thereof. These flanges are locked into the recesses 97&#34; and overlying flanges 98&#34; in the base unit 14&#34; as best seen in FIG. 27. A quarter turn rotation of the cone unit with respect to the base unit will lock the two parts together. FIG. 28 shows the tapered lower portion 21 on a modified support post 20&#34;. The base member 14&#34; has a similarly tapered recess 23 for receiving such modified support post. Obviously this modification could be applied to the cone/base unit combinations of the previously discussed figures. FIGS. 29 and 30 show a modification of the cone/base unit of FIGS. 26 and 27. Here the base unit 14&#39;&#34; has an internal center raised portion 17&#39;&#34; having thereon raised flanges 98&#39;&#34; which form spaced recesses 97&#39;&#34; therebetween. The over-all interlocking action is similar to that of the device in FIGS. 26 and 27. FIG. 34 shows a further embodiment of the base unit wherein the base unit instead of being of pan-like structure is of a flat type base construction. Interlocking flanges 98 are provided similar to those at 98&#34; and 98&#39;&#34; of FIGS. 27 and 30. The advantage of this flat surfaced base unit is that it may be stacked for transportation more easily than the pan type base units. A similar tapered socket 23 is provided in this base unit like that shown in FIG. 26. 
     A still further modification of component structure for the new and novel barricade system is disclosed in FIGS. 31, 32 and 33. Herein is shown on the base pan unit 14 with cone member 16 and support post 20 a warning light indicator structure 100. This structure has flanges 61&#39; forming recess 62&#39; therewith for receiving the lower flange portion 63 of an electrical flashing light device 60 as discussed previously. The structure 100 is square and rectangular as can be seen from the drawings. Each of the four vertical sides is provided with a slotted trough-like portion 102. The edges of these troughs 102 have flange portions 104 which form recesses 106 therewith. The purpose of these flanged recess portions is to receive either round or square reflector units 106, 108. Normal friction usually is adequate to retain the reflector units in spaced positions when the reflector head is mounted for use, but as shown in FIG. 31, retaining pins 110 may be added to support the respective reflectors. Again this device is shown as having a square socket portion 112 at the base thereof for receiving the square support post 20. However as mentioned previously round sockets and round support posts may be used. 
     As can be seen from the many figures of the drawings and many interrelated features of the component devices, over-all each of these devices cooperate in one way or another to form the novel barricade system of this invention. The various component devices are very useful in various combinations and offer the greater protection of properly constructed warning indicators not generally available in the field today. 
     The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
