This application is a Continuation-In-Part of application Ser. No. 07/570,313, filed Aug. 21, 1990, now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     The present invention relates to an adjustable, portable, wind-resistant vehicular sign display. In particular the present invention relates to improved adjustable posts for displaying sign banners in which the display includes a base used in combination with a parked motor vehicle. 
     Apparatus used as displays for flexible, outdoor sign banners are known in the art. The use of a trailer base with erect poles is known in the art. However, said systems are cumbersome and difficult to install. Other displays of signs include heavy bases which are awkward and difficult to move. In addition, sign post displays which do not provide a reliable locking system for the posts holding the display banner in place are unreliable, especially in meterological conditions of high winds. 
     THE PRESENT INVENTION 
     It is an object of the invention to provide an improved outdoor sign display system in which the system includes an integrated base. 
     A further object is to provide an improved sign display system in which the system includes a base which is easily adaptable to the tires of a parked motor vehicle so that the weight of the motor vehicle can provide stability for the display system. 
     A still further object is to provide an improved outdoor sign display system in which the base is provided into the structure of the system without adding unnecessary weight to the system. 
     More particularly, it is an object of the present invention to provide a base for sign display system in which a base is adaptable to a vehicle tire and then used as a stable base for retractable display posts and virtually without additional weight to the system, and at the same time provide a base that is reliably locked into positions by the tires of the motor vehicle to provide a system with maximum stability and reliability. 
     It is a further object of the invention to provide a sign display system which permits the taut display of flexible banners which provide flexibility in the event of vigorous outdoor winds. 
     SUMMARY OF THE INVENTION 
     The present invention overcomes the disadvantages of the prior art sign display system pointed out above by providing a system with a base adaptable to a motor vehicle. The base is placed beneath a tire of a vehicle when the display system is in an up or display position and the sign banner is supported by the two adjustable two side poles of the system when the system is in the display position. 
     The system includes two substantially vertical posts. Each post includes two substantially vertical, slidably biased sections in which the smaller section slides up and down within the cylindrical interior of the outer, larger post section connectable to the base adaptable to the vehicle tire. 
     The substantially verticle posts of each side are connected at the upper end by a horizontal banner sign. The vertical bars are connected at the distal end from the banner by means of the weight of the vehicle tires and provide stability for the base at the bottom end of the substantially vertical posts. Each base contains a plurality of boundary edges, with the edges having a circumferential lip protruding therefrom to define a limiting space for the vehicle tires and to provide barriers to prevent the movement of the tires when the motor vehicle is parked above each of the bases of the sign display system. 
     The walls of the circumferential lip extend upward from the sides of the base. One wall contains a clamping tube member to house the lower vertical tubular portion of each of the posts. The clamping tube member extends upward at the slight angle off a vertical access to accommodate the lowermost of the substantially vertical posts. 
     The substantially vertical posts of the sign display system are deviated outwardly at a slight acute angle off a vertical axis rising vertically from the horizontal base. The outward deviation of the posts off of the vertical axis prevents the posts from collapsing inward toward each other under high winds and adverse meteorological conditions, which may cause the flexible sign banners to billow, thereby threatening stability by pulling upright posts towards each other. 
     The Applicant&#39;s invention is important because it provides a vehicular display system for flexible banners including a means for preventing the inward collapsing of the posts holding the banners when the posts are subject to adverse winds and meteorological conditions. Under such adverse conditions, the flexible banner will tend to &#34;billow&#34; causing the vertical posts to slightly collapse inward and thereby scratch the vehicle by which the posts are held or perhaps the complete collapse and breakage of the posts. Therefore, the Applicant&#39;s device deviates the posts at a slight acute angle outwardly off of the vertical axis arising from the vertical base. The posts are pre-stressed to &#34;give&#34; under pressure to return to this slightly deviated angle after the posts have been forced inward by the mechanical application of wind driven force upon the billowing of the flexible banner sign display. 
     Furthermore, the position of the posts enables a flexible sign banner to remain taut while in the displayed position. 
     The vertical adjustability of trombone effect of the upper vertical post within the hollow lower vertical post permits adjusting the height of the sign banner, preferably rectangular in form. 
     The invention itself will be best understood when a preferred embodiment of the invention is described with reference to the accompanying drawings.

     DESCRIPTION OF THE INVENTION 
     Attention is directed to FIGS. 1 and 2, each of which shows a preferred embodiment of the invention from a different angle and in a different condition, respectively. The present invention is an adjustable, portable, wind-resistant vehicular sign display system. Instruments of this kind are generally referred to as &#34;sign display systems&#34;. 
     The system generally includes two substantially vertical posts. Each post includes two substantially vertical, slidably biased sections in which the smaller section slides up and down within the cylindrical interior of the outer, larger post section connectable to the base adaptable to the vehicle tire, providing for stability under inclement meteorological conditions. 
     The preferred structure of the present invention provides a vehicular sign display system as shown in FIG. 1. 
     Referring to FIG. 1, the vehicular sign display system contains two substantially tubular lower post sections 11 and 11a, which house substantially vertical slidably upper post sections 10 and 10a, respectively, when the system is not in use. Substantially biased posts 11 and 11a are placed in base housings 2 and 2a, respectively, which are adjustable to the size of the motor vehicle tires 3a and 3b. 
     Substantially vertical, slidably biased sections 10 and 10a are positioned at a height desired by the user, secured within the posts 11 and 11a at that height by fastener 14. 
     A principal feature of this invention is the ability of the substantially vertical posts 11 and 11a to maintain stability even under inclement meteorological conditions. FIGS. 3 and 4 show how this is accomplished. 
     Substantially vertical posts 1 and 1a are tilted at a biased angle C away from motor vehicle 3 by a distance AB, as shown in FIG. 4. The tilting of the posts allows for an inward &#34;give&#34; of the posts while under stress from sign banners billowing in the wind. Pliable rubber bumpers 15, 15a, 15b and 15c are placed upon lower post section 15 to prevent scratching or denting damage to the fender of the car adjacent to posts 1 and 1a. 
     Display banner 7 is affixed to posts 1 and 1a by the use of material which is placed through eyelet openings 5 and 5a at the distal end caps 4 and 4a of posts 1 and 1a. 
     The weight of tires 3 and 3a keep substantially vertical posts 1 and 1a, with extended sections 10, 11, 10a and 11a respectively in place. 
     Another embodiment of the invention is shown in FIG. 2, wherein bases 2a and 2b are positioned on the right front and right rear tires 3a and 3b, respectively. Substantially vertical posts 1a and 1b are secured by the weight of tires 3a and 3b resting upon bases 2a and 2b, respectively. In FIG. 2, substantially vertical, slidably biased upper post sections 10a and 10b extend from lower post sections 11a and 11b in the same manner as sections 10 and 10a do above from 11 and 11a in FIG. 1. 
     The base 2 of the display system contains a plurality of upward tubular lip edges 21, 22, 23 and 24, capable of forming a circumferential lip protruding above base floor portion 26 to define a limiting space for vehicle tires 3a and 3b and to provide barriers to prevent the movement of the tires when motor vehicle 3 is parked above each of the bases of the sign display system. 
     Substantially vertical lower post section 11 slidingly fits into housing member 25 at a mid point on edge 21 in base 2. Slidable upper post section 10 slides up from lower post section 11 and is secured in one of openings 13, 13a, etc. by fastener 14. Slidable lower post section 11 is capped at its distal end by a cap 4. 
     An alternate version of attaching display banner 7 to slidable section 11 is shown in FIG. 3a. Eyelet 5 is placed atop cap 4 through which banner attaching rope 6 may pass. 
     In another embodiment as shown in FIGS. 5 through 10, the post itself may be completely vertical, but the same effect of providing an angle for the posts is provided by first diverting the lower portion of each lower section of each post at a lower oblique angle outward and then the vertical rising of the upper portion of the lower section of the posts. The shape of the posts creates a spring-like resistance to any wind driven force which may billow the flexible sign display and cause the post to slightly collapse inward. Each post has a plurality of sections, the lower portion of the lower section being obliquely angled and the top portion being extended vertically upward. 
     Attention is directed to FIGS. 5 through 10, each of which shows another embodiment of the invention. This additional embodiment also is an adjustable, portable, wind-resistant vehicular sign display system. 
     This embodiment generally includes two substantially vertical posts in two sections. The first, outer base section rises at a slight angle off of the base, and then rises vertically to the point where an upper, inner section is inserted therein. The outer, larger post section is connectable to the base adaptable to the vehicle tire, providing for stability under inclement meteorological conditions. 
     Referring to FIGS. 5 through 10, the vehicular sign display system contains two posts 31 and 31a substantially tubular lower post sections 41 and 41a, having lower portions 42 and 42a and upper portions 43 and 43a, which house substantially vertical slidably upper post sections 50 and 50a, respectively, when the system is not in use. Substantially biased posts 41 and 41a are placed in base housings 62 and 62a, respectively, which are adjustable to the size of motor vehicle tires 3a and 3b. 
     Substantially vertical, slidably biased sections 50 and 50a are positioned at a height desired by the user, secured within post sections 43 and 43a at that height by fastener 54. 
     A principal feature of this invention is the ability of the substantially vertical posts 41 and 41a to maintain stability even under inclement meteorological conditions. 
     The lower portions 42 and 42a of lower sections 41 and 41a substantially vertical posts 31 and 31a are tilted at a biased angle away from motor vehicle 90. The tilting of the posts allows for an inward &#34;give&#34; of the posts while under stress from sign banners billowing in the wind. Pliable rubber bumpers 55, and 55a are placed upon the upper sections 43 and 43a of lower post sections 41 and 41a to prevent scratching or denting damage to the fender of the car. 
     Display banner 70 is affixed to upper sections 50 and 50a posts 31 and 31a by the use of material which is placed through eyelet openings 75 and 75a at the distal end caps 74 and 74a of posts 41 and 41a. 
     The weight of tires 90a and 90b of vehicle 90 keep substantially vertical posts 31 and 31a, with extended sections 50, 41, 50a and 41a respectively in place. 
     The bases 62 and 62a of the display system contains at least one of upward tubular lip edges 81 and 81a, capable of forming a limiting lip protruding above base floor portions 86 and 86a to define a limiting space for vehicle tires 90a and 90b and to provide barriers to prevent movement of the tires when motor vehicle 90 is parked above each of the bases of the sign display system.
