- the stabilizing means 85 consists of a rib 86, mounted on one side of the collar 81, by means of a weldment 87.
- the rib 86 extends angularly outwardly and upwardly with respect to the collar 81 and is adapted for insertion through an aperture 101, provided in the sign thereby to stabilize the sign 100, supported on the structure.
- the collar 81 is further provided with third stop means 90, for locking the collar 81, in the stabilizing position.
- the third stop means 90 consists of an aperture 91 disposed in one side of collar 81, and having a threaded nut 92, mounted on the outside surface of the collar 81, overfacing the aperture 91.
- a set screw 93 is threadedly mounted through the nut 92, whereby the inner end of the set screw 93, will contact the second tubular bar 40, when the screw 93, is screwed into the nut 92.
- FIG. 3 the details of the second yoke means 45, and more particularly, the central tubular housing 46, the first angular tube 48, and the second angular tube 49, are illustrated.
- the tubular housing 46, and the first and second angular tubes 48 and 49 respectively, are shown to be in form of substantially square tubes.
- These structures function as warning flag holders, and in the preferred embodiment, are substantially square in order to accommodate both square and round shaft flags.
- FIG. 4 illustrates the relative positioning of the third yoke means 60, consisting of the collar 61, and having the lock means 70, engaged, the first tubular bar 10, the tube guide 17, and the second tubular 40.
- the positioning of the pin 58 is shown in the engaged position thereby to maintain the second tubular bar in the telescoped position.
- FIG. 5 the details of the pivotal mounting of the legs 25 on the first yoke means 21 is illustrated in detail.
- the flattened section 26 of the leg 25 is mounted between the arms of the associated second U-shaped attachment flange 23 by means of a lock bolt 28 in a loose-fitting arrangement. With such construction, lateral movement of the legs 25 is facilitated which adds to the stability of the structure when carrying a sign 100 thereon.
- FIG. 6 illustrates the details of the pivotal mounting of the support bar 30 on the leg 25.
- the outer end 31 of the supportbar 30 is mounted between the arms of the associated U-shaped support flange 29 by means of an outer lock bolt 33, once again in a loose-fitting arrangement to add stability.
- FIG. 6 further illustrates the preferred construction for the legs 25 to be in the form of a 90 angle iron. With this construction, each leg 25 has two support points at itslower end 12 for resting upon an underlying support surface thereby once again adding to the stability of the structure.
- the support structure is transported to the situs of use in the collapsed position wherein the pin 58 is withdrawn and the second tubular bar 40 telescoped downwardly until the lower end of the central tubular housing 46 is resting against the upper edge of the collar 81 of the fourth yoke means 80, and the collar 22 of the first yoke means 21 is slid upwardly along the first tubular bar until the legs and the support bars are substantially flush against the first tubular bar 10.
- the collar 22 of the first yoke means 21 is slid downwardly along the first tubular bar 10 until the legs 25 are spread apart to the distance permitted by the support bars 30.
- the second tubular bar 40 is then telescoped upwardly until the bottom guide plate 43 is raised abovethe apertures 13 in the first tubular bar 10 and then the pin 58 is inserted therethrough.
- the upper edge of the sign 100 is then placed in the inverted slot 56 of the first sign engagement means 50 and the lower edge thereof is placed in the slot 68 of the second sign engagement means 62.
- the fourth yoke means 80 is then slid along the second tubular bar 40 until the rib 86 is inserted through the aperture 101 in the sign 100.
- the steps are merely reversed whereby the sign 100 is easily removed and the structure collapsed for easy transport to another location or for storage.
- the first stop means 15 is provided in order to prevent the accidental inversion of the legs 25 and support bars 30 should an operator lift the entire structure off of the underlying support surface. In this event, the first yoke means 21 would tend to travel downwardly thereby causing the legs 25 and the support bars 30 to become inverted. In this position, some difficulty could be encountered by the operator in attempting to right the structure.
- the sign engagement means may be constructed in the form of heavy-duty clips rather than slots; the various stop means and lock means may be varied; the stand means may be varied; the stabilizing means may consist of clips mounted on the rear surface of the sign with clip receiving means on the fourth yoke means in place of the rib structure disclosed in the preferred embodiment herein.
- the various component parts of the support structure are preferably formed of steel bar stock in order to produce a relatively heavyweight structure.
- the first tubular bar 10 is a hollow bar formed of steel tubing while the second tubular bar 40 is formed of a solid steel bar.
- the'weight of the second tubular bar 40 urges the inverted slot 56 of the first sign engagement 50 into intimate contact with the top edge of the sign 100.
- the legs 25 and associated elements of the stand means 20 are formed of heavyweight steel bar stock whereby the center of gravity of the structure'as a whole is sufficiently close to the lower end thereof whereby good stability is achieved.
- the support structure of this invention is provided with sign engagement means which are adjustable in order to accommodate various sizes of signs and and adjustable whereby the relative distance between the lower edge of the sign and the underlying support surface may be adjusted to the desired height.
- sign engagement means which are adjustable in order to accommodate various sizes of signs and and adjustable whereby the relative distance between the lower edge of the sign and the underlying support surface may be adjusted to the desired height.
- This feature is of great im-- portance in view of the fact that the various government agencies both federal and state, have different requirements in terms of the distance the sign must be raised from the road surface whereby this support structure may be used for jobs in all states.
- the support structure of this invention minimizes the number of moving parts which must be manipulated by the operator for assembly and disassembly thereof. Also, this support structure eliminates the need for additional weighted elements for stabilizing'the structure on an underlying support surface by virtue of the manner of construction.
