ROAD SIGN STANDARDS Filed May 26, 1958 FIG. 3
LOWELL C CARPENTER INVENTOR.
ATTORNEY.
United States Patent C) 2,995,847 ROAD SIGN STANDARDS Lowell C. Carpenter, 8084 SE. 15th Ave., Portland, Oreg. Filed May 26, 1958, Ser. No. 737,696 Claims. (Cl. 40-125) My invention relates to a collapsible road sign standand for display of various kinds of road warning signs. It is of such a design that the sign is freely swingable which eliminates the tendency of the standard to be blown over or upset by wind gusts created by natural forces and the passage of vehicles.
One of the objects of my invention is to provide a road sign standard that will pivotally mount the warning sign.
A further object of my invention is to provide a portable and collapsible road sign standard that will not easily be upset by wind gusts.
A still further object of my invention is to provide a collapsible and portable road sign standard that is simple, inexpensive and effective.
Other and further objects of my invention will be apparent from the drawings, specifications and claims herein.
Referring to the drawings:
FIG. 1 is a front elevational view of the collapsible and portable road sign standard with a sign mounted thereupon.
FIG. 2 is an end elevational view of the collapsible and portable road sign standard, showing a portion of an arc traced by the lower end of the sign as it swings.
FIG. 3 is a fragmentary detail end view on an enlarged scale, showing the mounting of a sign to the pivoted crossbar, the pivotally mounted leg and stop element therefor and the fixed leg.
Referring further to the drawings:
The collapsible sign standard consists of two end plates 10. Each end plate 10, which is preferably formed from flat stock, has rigidly attached to one side edge thereof a leg 11 which is preferably formed from angle iron. To the opposite side edge of the plate a leg 12 is pivotally attached by means of a bolt, pin or rivet 13. Each plate 10 is also provided with a centrally positioned hole near its top marginal edge and also has a substantially L-shaped stop element 14 rigidly secured to its lower marginal edge in such a position that the leg 12 will be prevented fiom further outward travel once it has reached the fully opened position. If desired, the end plate 10 and stop 14 may be formed as a one-piece unit, for easting these elements as one unit from a ductile steel has been found to be very satisfactory. The leg 12 is likewise preferably formed from angle iron; and a pin, or other stop element, 15 is inserted into matching holes drilled through said leg 12 and the stop element 14. The holes in each of these elements align when the leg 12 is in the fully opened position. Pin 15 inserted through said holes prevents the leg 12 from pivoting toward or closing with leg 11. A lateral brace element 16 ties the two legs 12 together at a point which is a short distance above the bottom ends or feet 18 of said legs 12. The rigidly secured legs 11 are also tied together by a lateral brace element 17 secured a short distance above the feet 19 of said legs. Gusset bars 16' are rigidly secured to the lateral brace 16 at each end thereof on an angle of approximately 45 to said brace 16 and the adjacent collapsible leg 12. Gusset bars 16 are likewise secured in this same relative position at each end of the lateral brace 17 between it and the legs 11.
A sign-carrying bar 20, preferably fabricated from angle iron, is pivotally secured between the end plates 10 near the top marginal edges thereof by means of element 21 which is preferably a rivet, bolt, pin, etc., inserted 2,995,847 Patented Aug. 15, 1961- through said hole near the top marignal edge of each of said plates 10 in such a manner that it cannot be pulled on through the hole, such as having an enlarged head which forms a shoulder against the outer surface of the plate 10. The rivet 21, however, will freely move rotat ably within said hole. The inner end of each of said rivets, etc., 21, is rigidly secured to a portion of the face surface near the end of the sign-carrying bar 20 by welding or other suitable means. A Washer 22 is provided between each end of the sign-carrying bar 20 and its adjacent end plate 10, said washers being placed upon the rivets 21 before the same are secured to the sign bar 20. It is preferred to secure the rivets 21 to the fiat face surfaces of the sign bar 20, substantially as shown in the drawings. However, the inner ends of the rivets 21 may be secured at the inside corner formed on the back surface of the angle iron sign-carrying bar 20. The latter attachment arrangement makes the actual assembly and alignment of the sign bar easier.
A flag holder 24 of any suitable stock such as tubular, etc., is secured medially of the sign-carrying bar 20 on the back side thereof and preferably disposed at an angle of approximately 45 thereto. A flag 27 may be inserted in the flag holder 24, if desired. Storage or carrying straps 23, generally hook-shaped in design, are secured near each end of the sign bar 20 in such a manner that the whole sign standard may be stored thereby, hooked over the tailgate of a truck, etc. A sign 25 is detachably secured to the sign bar 20 in any suitable manner such as by bolts 26. Said sign 25 is so positioned that it will clear each of the end plates 10 and will also miss the lateral brace elements 16 and 17 when it is caused to swing to and fro by any means such as the action of natural wind gusts or by any gusts or air currents caused by the passage of vehicles. The sign 25 should be mounted in such a position upon the sign bar 20 that a substantially greater portion of its vertical weight will depend below the sign bar. This manner of attachment causes the sign to present an unbalanced surface to any wind gusts or air currents, so that the sign will readily yield to such currents rather than create a pressure against the standard itself, thus tending to cause upset or blowdown. If the sign 25 were to be mounted too closely to the exact vertical midpoint thereof, a substantially balanced arrangement would be effected which would tend to create the undesirable results of the sign assuming an attitude difficult for motorists to see in calm weather and also of presenting a balanced surface to wind gusts, so' that the leverages against the top portion and lower portion of the sign Would tend to offset each other and thereby present an unyielding surface to the wind.
The foot ends 18 and 19 of the legs 12 and 11, respectively, are preferably so formed that their bearing surfaces will be disposed at substantially a angle to the longitudinal front and rear edges of each leg. This arrangement presents sharp pointed bearing surfaces to the road shoulder or roadway upon which the standard may be placed, and the feet 18 and l9 of said legs thus tend to dig in and further resist the tendency of the standard to be upset or collapsed by wind gusts or currents.
It is understood that certain variations or modifications of the disclosures herein specifically set forth are feasible without departing from the spirit of my invention and that I am not, therefore, limiting myself to the specific disclosures herein set forth which are merely preferred embodiments of my invention.
