Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to signs and, more particularly, pertains to structures for holding signs, such as road and street signs.




2. Description of the Prior Art




Over the years, various systems have been developed for securing signs, such as road signs, to a post, a pole or the like. For instance, U.S. Pat. No. 1,802,939 issued on Apr. 28, 1931 to Butler discloses a sign mounting system comprising a split sleeve adapted to be drawn together about an upstanding post by means of a first pair of bolts. Each sleeve section is provided with at least one sign-holder defining a socket within which one end of a sign may be secured by a second pair of bolts. Accordingly, to install a sign, one has to first tighten the first pair of bolts in order to secure the split sleeve to the post and then tighten the second pair of bolts to secure the sign to the sign-holder. Therefore, the installation of the sign necessitates a number of operations which are time consuming.




It has also been proposed, as disclosed in U.S. Pat. No. 4,548,377 issued on Oct. 22, 1985 to Huel, to secure a sign to a post by means of a pair of straps effective for retaining the sign to a bracket as well as fastening the bracket to the. post. However, when it is desired to remove the sign, it is necessary to detach the bracket from the pole, as it is the straps which directly hold the sign in position with respect to the bracket.




Although the sign mounting systems described in the above mentioned patents are effective for attaching a sign to a post, it has been found that there is a need for a sign mounting system which facilitates the installation and removal of a sign from a support structure.




SUMMARY OF THE INVENTION




It is therefore an aim of the present invention to provide an improved sign mounting system which offers ease of assembly and disassembly.




It is also an aim of the present invention to provide such a sign mounting system which is relatively simple and economical to manufacture.




Therefore, in accordance with the present invention, there is provided a system for mounting a sign to a structural member, comprising a clamp adapted to be mounted about the structural member, said clamp including at least a pair of gripping members adapted to cooperate for holding the sign therebetween, and securing means adapted to be engaged with said clamp to retain said gripping members in gripping engagement with the sign, while at the same time securing said clamp to the structural member.




Also in accordance with the present invention, there is provided a combination mounting system and sign for mounting to a structural member, said mounting system comprising a bracket adapted to be mounted about the structural member, said bracket having a pair of gripping members displaceable between an open position for allowing said sign to be inserted therebetween and a closed position for holding said sign, actuator means extending transversely through said gripping members for displacing said gripping members between said open and closed positions thereof, and at least one slot defined in said sign, said slot having an open end to accommodate a portion of said actuator means located between said gripping members, thereby allowing said sign to be installed and removed from said bracket without having to disengage said actuator means from one of said gripping members.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Now Referring to the drawings, and in particular to

FIGS. 1 and 2

, a sign mounting system embodying the element of the present invention and generally designated by numeral


10


will be described.




More particularly, the sign mounting system


10


generally comprises a sign


12


held by a clamp or bracket


14


mounted around a vertical post


16


.




As seen in

FIG. 2

, the clamp


14


is formed as a partial ring or collar


17


at opposed free ends of which a pair of parallel gripping arms


18




a


and


18




b


extend so as to define a gap therebetween for receiving the sign


12


. The gripping arms


18




a


and


18




b


define respective transversal bores


19




a


and


19




b,


which are placed in register for allowing a bolt or actuator means


20


to be driven therein so as to displace the gripping arms


18




a


and


18




b


towards each other while, at the same time, causing the collar


17


to contract around the post


16


. A washer


22


may be disposed between the head of the bolt


20


and the gripping arm


18




b,


as is well known in the art.




According to the embodiment illustrated in

FIG. 2

, the bore


19




a


is provided with internal threads


23


for cooperating with the external threads of the bolt


20


, whereas the bore


19




b


is delimited by a smooth surface. However, it is understood that both bores


19




a


and


19




b


could be provided with threads.




The thickness of the gripping arm


18




a


may be greater than that of the gripping arm


18




b


to maximize the length of the bore


19




a


and, thus, allow for the formation of a greater number of internal threads


23


, thereby allowing for a wider range of contraction of the clamp


14


through the operation of the bolt


20


.




The bolt


20


is provided with a head


25


which is configured to overlie a portion of the surface of the gripping arm


18




b


surrounding the bore


19




b.


Accordingly, continuous advancement of the bolt


20


through the bore


19




a


will urge the undersurface of the head


25


against the gripping arm


18




b,


thereby drawing the gripping arm


18




b


towards the gripping arm


18




a


to a closed position wherein the sign


12


is held tightly captive between the gripping arms


18




a


and


18




b.






As seen in

FIG. 1

, the sign


12


defines a L-shaped slot


24


having an open end for allowing the bolt


20


to be engaged within the slot


24


without having to remove the bolt


20


from the bore


19




a.


Therefore, one only has to loosen the bolt


20


such that the gripping arms


18




a


and


18




b


release the sign


12


and allow for the sign


12


to slide therebetween.




To install the sign


12


, the collar


17


is first slidably fitted over the upper end of the post


16


down to a selected position. Then, the bolt


20


is tightened so as to draw the gripping arms


18




a


and


18




b


to an intermediate position, wherein the collar


17


is sufficiently collapsed inwardly to ensure that the collar


17


will remain in position on the post


16


. Thereafter, the sign


12


is inserted between the gripping arms


18




a


and


18




b


so as to position the portion of the bolt


20


extending between the gripping arms


18




a


and


18




b


in the bottom


26


of the slot


24


. Then, the bolt is further tightened to cause the arms


18




a


and


18




b


to tightly clamp onto the sign


12


. The inside surfaces of the arms


18




a


and


18




b


each define a ridge which bites into the sign


12


to prevent the latter from coming out.




One advantage of the present invention resides in the fact that when, it is desired to replace the sign


12


with a similar or different sign, one has just to slightly loosen the bolt


20


such that the gripping arms


18




a


and


18




b


allow for the sign


12


to slide therebetween. Indeed, because of the openended slot


24


, it is not necessary to completely unscrew the bolt


20


from at least the bore


19




a


to remove the sign


12


from the clamp


14


.




According to the embodiment illustrated in

FIG. 1

, the clamp


14


is of unitary construction and is made of metal.




It is understood that more than one clamp


14


may be provided for supporting a single sign, particularly when the size and the weight of the sign are considerable. In these cases, a number of L-shaped slot


24


corresponding to the required number of clamps


14


would be defined in the sign


12


.





FIGS. 3 and 4

illustrate a second embodiment of the present invention, wherein a clamp


14


′ is split into two distinct sections


28




a′


and


28




b


′, each of which is composed of a semi-circular central portion


30


′ from which extend a pair of diametrically opposed gripping arms


18




a


′ and


18




b′.






To draw the sections


28




a


and


28




b


together about a post


16


′, the gripping arms


18




a


′ and


18




b


′ of the section


28




a


′ are respectively placed in register with the associated gripping arms


18




b,


and


18




a


′ of the section


28




b


′, and two bolts


20


′ are threadably engaged with respective pairs of gripping arms


18




a


′ and


18




b′.






As seen in

FIG. 4

, this construction of the clamp


14


′ is intended to support a pair of signs


12


′ extending in diametrically opposed manner from opposite sides of the post


16


′.




The signs


12


′ are installed and removed as per the way described hereinbefore with respect to the embodiment of

FIGS. 1 and 2

.





FIGS. 5

to


7


illustrate a third embodiment of the present invention, wherein an auxiliary gripping member


32


, having an inverted U-shaped configuration, is slidably fitted on gripping arms


18




a


″ and


18




b


″ so as to partly extend beyond a free end portion thereof. The auxiliary gripping member


32


comprises a top wall


34


on opposed sides of which a pair of downwardly extending side walls


36


depend. A pair of registered bores


38


are defined in the side walls


36


to form a transversal passage for a bolt


20


″. As seen in

FIGS. 5 and 6

, the bores


38


are aligned with the bores


19




a


″ and


19




b


″ defined in the gripping arms


18




a


″ and


18




b


″ and with the bottom, or closed, portion of slot


24


″ for allowing the passage of the bolt


20


″ through the gripping arms


18




a


″ and


18




b″.






As seen in

FIGS. 6 and 7

, a pair of opposed aligned bulbous projections


40


extend inwardly from the bottom edges of respective side walls


36


for frictionally engaging the sign


12


″. A pair of opposed Y-shaped projections


42


and a pair of opposed inclined bulbous projections


44


extend inwardly from the portion of the side walls


36


extending beyond the free end portions of the gripping arms


18




a


″ and


18




b


″ to further frictionally retain the sign


12


″ and, thus, increase the rigidity of the connection between the sign


12


″ and the clamp


14


″.




It is noted that the auxiliary gripping member


32


may be installed on the sign


12


″ prior to being mounted to the gripping arms


18




a


″ and


18




b


″ or after having been secured thereto by means of the bolt


20


.




The third embodiment also differs from the first and second embodiments in that the region of the sign


12


″ to be engaged by the gripping arms


18




a


and


18




b


is thicker than the remaining portion of the sign


12


″ to provide increased rigidity.




The signs


12


,


12


′ and


12


″ and the auxiliary gripping member may be formed by extrusion. The signs


12


,


12


′ and


12


″ may be formed of polycarbonate.




Although the present invention has been described in connection with a vertical post


16


/


16


″, it is understood that the sign mounting systems


10


,


10


′ and


10


″ may be used with other structural or support members forming part of a given display arrangement.
