Description




BACKGROUND OF THE INVENTION




The present invention pertains to a mounting bracket. More particularly, the present invention pertains to a mounting bracket having a flexible locking arm to enable secure attachment to a mounting base such as a rack vertical beam.




Sign display is a vitally important function for the retail industry. The principle function of a sign in a retail trade or store is to notify consumers of particular information about the product. While signs are quite effective in directing the consumers attention to a particular location, item or product, because the signs and the brackets from which the signs hang, can extend into an aisle way, they can be susceptible to damage from collisions with shopping carts, forklifts, or people. Thus, it is important that the sign mounting bracket maintains a secure connection to the base to ensure that the sign remains securely intact for viewing, while being sufficiently sturdy to withstand the weight of the attached sign or display and any inadvertent contact.




Typically mounting brackets are made out of relatively rigid heavyweight materials, such as metal. Although a rigid or metal bracket may provide an effective secure connection with the base and have a sturdy frame capable of withstanding the weight of a hanging display, the cost in manufacturing a metal bracket can be relatively expensive. Furthermore, a rigid bracket may not readily absorb the impact of a collision, and to this end, may become damaged, bent or broken upon such a collision.




In addition, one requirement of such mounting brackets is ready installation. Many brackets require fastening to the display using mechanical fasteners, such as nuts, bolts, screws and the like. While these fasteners provide acceptable attachment vis-a-vis strength and integrity, they can be quite labor intensive to install. Thus, brackets that use these fasteners may not be acceptable, particularly in those instances where many such signs are to be installed or mounted.




One conventional flexible bracket used in mounting systems has a two prong latching connection for attaching to the mounting system or display. One disadvantage of this type of brackets is that the two prongs are susceptible to bending and thus becoming disengaged in a small-scale collision. Further, because the brackets are flexible, the two-prong connection may not provide a secure locked connection with the mounting system.




Accordingly, there exists a need for a display bracket that is easy to manufacture and provides a secure lockable connection to a mounting base. Most desirably, the mounting bracket is flexibly designed and is properly reinforced to enable hanging a display or sign and to withstand inadvertent impact. Such a bracket is cost effective to manufacture and requires minimal or no external hardware for installation.




SUMMARY OF THE INVENTION




A bracket for mounting an associated sign to an associated post includes a post mounting portion and a coupling portion for mounting the sign to the bracket. A post to which the bracket is mounted post has at least three linearly arranged slots formed therein and defines wall portions between the slots and a lip at the slot. The post has an exterior surface and an interior surface.




The bracket is formed from a flexible, resilient material and includes a main body portion having first and second retaining elements spaced from one another. The retaining elements are configured for engagement with the post by insertion into first and second post slots. The retaining elements engage the interior surface of the post at the slots. Preferably, the retaining elements have a hook shape defining a shoulder that engages the interior surface of the post. The bracket includes a coupling portion for mounting the sign to the bracket.




The main body portion is arcuate and extends away from the post intermediate the first and second retaining elements. A flexible locking arm extends from the main body portion intermediate the first and second retaining elements. The locking arm has a portion that extends non-linearly from the main body portion. Preferably, the non-linear portion extends along the arcuate shape of the main body portion.




The locking arm includes a latching element for insertion into and engagement with a third post slot intermediate the first and second post slots. The latching element engages the post at the slot to maintain the bracket secured to the post.




In a present embodiment, the latching element includes a head portion insertable into the third post slot. The latching element includes a first detent for engaging the slot lip. Preferably, the latching element also includes a second detent for engaging the slot lip, with the first and second detents being adjacent one another.




The locking arm can include a flange extending transversely therefrom. The flange extends along a portion of the locking arm and terminates prior to a juncture of the locking arm and the bracket main body. The flange provides a finger or gripping region for bending (e.g., flexing) the arm to install or lock the bracket to the post.




The main body portion can include a curved flange extending along an outer portion of the arcuate shape. The flange has a length such that it extends beyond the first and second retaining members and is configured to rest against the post when the bracket is in place thereon.




The coupling portion can be formed on the bracket spaced from the main body portion. This provides a mounting for the sign that is spaced from the post to which the bracket is mounted. A beam can extend between the coupling portion and the main body portion. An angled truss can extend between the main body portion and the beam proximal the coupling portion to provide additional support for the sign and rigidity to the bracket.




These and other features and advantages of the present invention will be apparent from the following detailed description, the accompanying drawings and appended claims.

DETAILED DESCRIPTION OF THE INVENTION




While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred embodiment with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiment illustrated. It should be further understood that the title of this section of this specification, namely, “Detailed Description Of The Invention”, relates to a requirement of the United States Patent Office, and does not imply, nor should be inferred to limit the subject matter disclosed herein.




Referring now to the figures, and in particular

FIG. 1

, there is shown a mounting bracket


10


embodying the principles of the present invention. The mounting bracket


10


is mounted to a conventional mounting base


12


, which is shown in FIG.


2


. An exemplary base


12


is an upright


32


having a plurality of spaced channels or slotted openings


14




a-f


, enabling the bracket


10


to interlock with the base


12


. In a typical application, the upright


12


will be one of a number of vertical posts to, for example, support a pallet rack. In an interlocked state, the mounting bracket


10


extends outwardly from the mounting base


12


, as shown in

FIG. 2

, enabling an associated sign or display (not shown) to hang from the bracket


10


.




The mounting bracket


10


is formed as an integral member and includes a first portion


16


for mounting to the base


12


that is contiguous with a second portion


18


from which a sign is mounted. The base mounting portion


16


includes an intermediate main support bar


20


extending between a coupling portion


22


and an adjoined beam


24


and truss


26


combination.




The mounting bracket


10


is formed from a molded plastic, polymeric or like resilient material, which enables flexible manipulation of the bracket


10


for connection to the mounting base


12


. Notably, it is contemplated that the mounting bracket


10


can be formed from any resilient material without departing from the scope of the present invention.




The main support bar


20


has upper and lower edges or flange


28


,


30


, that extend along the bar


20


to provide stability to the bar against bending or flexing and to provide the bar


20


with additional structural reinforcement.




The coupling portion


22


is integrally connected to (e.g., formed as part of) an end of the bar


20


. The coupling portion


22


includes a connecting arm


32


and a wedge-like element


34


, configured for receipt in and connection to the sign or display (not shown). One exemplary arrangement for securing the coupling portion


22


to the sign is disclosed in Padiak et al., U.S. Pat. No. 5,933,932, which patent is commonly assigned herewith and is incorporated herein by reference.




The wedge


34


and connecting arm


32


are configured for receipt in an opening defined in the sign or display support or channel. As disclosed in the aforementioned patent to Padiak et al., the wedge


34


has a head


36


that cooperates with the sign support to prevent it from sliding or disengaging from the bracket


10


.




The angled truss


26


and extending beam


24


combine in an adjoining manner for integral connection to the support bar


20


. The beam


24


projects in a generally horizontal direction from the support bar


20


, thus providing connection to the second or sign mount portion


18


. The extended beam


24


engages the sign mount portion


18


in a generally upper region of a mounting portion


38


.




The angled truss


26


extends from the support bar


20


to the sign mount portion


18


. Preferably, the truss


26


engages a lower region of the mounting portion


38


. The truss


26


has a supporting bottom edge or flange


40


, which stabilizes the truss


26


against bending.




The mounting portion


38


provides a secure connection to the mounting base


12


. Referring now to

FIG. 2

, the mounting portion


38


has a curved or arcuate configuration, and includes a first spine mount


42


, a flexible locking arm


44


and a second spine mount


46


. The first and second spine mounts


42


,


46


, in association with the locking arm


44


securely lock the bracket


10


to the base


12


. The first and second spine mounts


42


,


46


extend from a curved main support body


48


.




The support body


48


has a curved flange


50


that enhances stability and structural integrity of the mounting portion


38


. As illustrated in

FIGS. 1 and 2

, the curved flange


50


extends along a portion of the support body


48


at an outer region of the arc. The flange


50


facilitates securing the bracket


10


to the base


12


. The flange


50


has a length somewhat longer than that of the mounting portion


38


, and extends beyond the first and second spine mounts


42


,


46


.




The first spine mount


42


has a hook-like shape and includes a head portion


52


terminating at a shoulder or retaining element


54


at one end and extending to the other end into a rounded region


56


. Similarly, the second spine mount


46


has a hook-like shape and includes a head portion


58


terminating at a shoulder or retaining element


60


and rounded region


62


. Notably, the head portion rounded regions


56


,


62


can take any shape to facilitate insertion into the mounting base slots


14


.




The flexible locking arm


44


provides for secure locking engagement with the mounting base


12


, to fasten the bracket


10


into position on the base


12


. The locking arm


44


extends from a generally intermediate region (as indicated at


64


) of the support body


48


, extending arcuately along the body


48


. In a current embodiment, the arm


44


extends in an upward direction, toward the first spine mount


42


. A supporting flange


66


extends along a portion of the locking arm


44


to provide a finger hold for installation and removal.




The locking arm


44


has a rounded head


68


portion that extends outward from the locking arm


44


, and is configured for insertion into an opening


14




c


, between the openings


14




b


,


14




e


, into which the first and second spine mounts


42


,


46


insert into the base


12


. An upper portion of head


68


terminates at a latching member


70


. The latching member


70


has a plurality of graduated steps


72


,


74


that define detents


76


,


78


. As illustrated in

FIG. 2

, upon insertion into a selected opening (such as


14




c


), one of the steps


72


or


74


engages an outer surface


80


of the base


12


, while a corresponding detent


76


or


78


engages a lip portion


82


of the opening


14




c.






Referring again to

FIG. 2

, the base


12


has the openings


14




a-f


formed therein, spaced apart from one another. As illustrated, each opening


14




a-f


is configured to receive a spine mount


42


,


46


or the locking arm


44


. Each opening


14




a-f


is separated from each adjacent opening by a portion, as indicated at


84


, of the base wall W that defines the lip


82


. The wall W also defines an interior surface


86


of the base


12


that is engaged by the spine mount shoulder


54


,


60


when the bracket is in place.




The bracket


10


is locked into the base


12


, by inserting the first and second spine mounts


42


,


46


into openings


14




b


,


14




e


, respectively, and the locking arm


44


into opening


14




c


. As is readily apparent from

FIG. 2

, when the bracket is urged downwardly, the shoulders


54


and


60


are positioned against the interior surface


86


. The locking arm head


68


inserts into opening


14




c


between those openings


14




b


,


14




e


into which the first and second spine mounts


42


,


46


insert.




To provide a stabilizing lock, the locking arm


44


is flexed or compressed from a resting position (

FIG. 1

) into an engaging position FIG.


2


). To compress the arm


44


, the flange


66


is pulled back (toward the coupling member


22


) until one of the detents


76


or


78


engages the opening


14




c


lip


82


. The latching member


70


thus engages opening


14




c


with a comer of the lip


82


positioned in one of the detents


76


or


78


. In this manner, the arm


44


is locked onto the base


12


in both the horizontal and vertical directions.




Because the arm


44


is pulled or flexed toward the body


48


to engage the latching member


70


with the opening


14




c


, the natural tendency of the arm


44


is move back to the resting position (FIG.


1


). Thus, the arm


44


exerts a force against and into the base


12


. This places a tension in the spine mounts


42


,


46


thus enhancing the “locking” feature of the bracket


10


to the base


12


. That is, the spine mounts


42


,


46


are generally aligned with one another (as indicated at L in FIG.


1


), and the arm head


68


is out of alignment with the mounts


42


,


46


. When the head


68


is inserted into opening


14




c


and the arm


44


is flexed rearward (toward body


48


) to lock to the base


12


, the head essentially aligns with the mounts


42


,


46


(as seen in FIG.


2


).




In addition, as seen in

FIG. 2

, the wall W portion


84


is captured between the first mount


42


and the latching portion


70


. This provides a more secure engagement of the bracket


10


to the base


12


. Moreover, when latching the latching member


70


to the base


12


, it is necessary to flex the entirety of the body


48


. Thus, the body ends


88


,


90


provide an additional tension-like locking feature of the bracket


10


to the base


12


.




A present embodiment of the bracket


10


is provided with two steps


72


,


74


. As will be appreciated by those skilled in the art, the base


12


can be formed (e.g., manufactured) having a variety of wall W thicknesses, as indicated at t, in FIG.


2


. To this end, the number or steps


72


,


74


formed in the bracket


10


can vary accordingly to permit use of the bracket


10


with a variety of upright


12


support designs and sizes.




To unfasten the mounting bracket


10


from the mounting base


12


, the locking arm


44


is moved from the engaging position with opening


14




c


by urging or pulling the arm


44


(by the flange


66


) rearwardly or back toward the body


48


. This unlocks the detent


76


or


78


from the lip


82


. The first and second mounts


42


,


46


are then removed from the base


12


by unhooking or upwardly urging the bracket


10


to disengage the shoulders


54


,


60


from the interior surface


86


.




From the foregoing, it will be observed that numerous modifications and variations can be effectuated without departing from the true spirit and scope of the normal concepts of the present invention. It is to be understood that no limitation with respect to the specific embodiments illustrated is intended should be inferred. The disclosure is intended to cover by the appended clams all such modifications as fall within the scope of the invention.
