Abstract
A clip for securing a picket cap to a profile of a picket fence consists of a U-shaped thin piece of stainless steel, or other suitable material, for frictionally fitting onto opposing end tabs protruding from a bottom portion of the picket cap. A backface of the picket clip has a barb-like portion formed thereon, and bent into an interior portion thereof for permitting the clip to be pushed onto one of the opposing tabs of the picket cap, but preventing the removal of the clip therefrom by digging into the material of an inside wall portion of the associated tab if an attempt is made to remove the clip from the associated tab. One such clip is installed on the two opposing tabs. The front face of the clip includes a topmost barb portion comprising one or more projecting teeth bent away from the clip, for digging into an inside wall portion of a recess in the top of an associated vertical profile into which the tabs of the picket cap are inserted, to prevent removal of the associated picket cap from the profile.
Description




FIELD OF THE INVENTION




The present invention relates generally to picket fences, and more particularly to picket fences fabricated from plastic components, and mechanisms for securing picket caps to profiles or slats of the fence.




BACKGROUND OF THE INVENTION




Picket fences fabricated from plastic materials, and other artificial materials, typically require the use of adhesives, screws, and so forth for securing the various components of the fence together. The use of screws for securing components of a picket fence together can be time consuming, and the screws can come loose over time. Also, the use of adhesives is not only time consuming for securing parts together, but requires extra clean up measures. One particularly troublesome area in assembling picket fences fabricated from plastic materials is the securement of picket caps to vertical profiles or slats of a picket fence.




SUMMARY OF THE INVENTION




One object of the invention is to provide an improved mechanism for securing a picket cap to a vertical profile of a picket fence consisting of plastic material.




Another object of the invention is to provide an improved mechanism for securing a picket cap to the top end of a profile of a picket fence of plastic or similar material.




With these and other objects in mind, and in view of the problems in the art, the present invention includes generally U-shaped clips of appropriate material for installation on opposing end tabs of a picket cap. A backside of the clip includes an inwardly extending and downwardly projecting partial cut-out portion for providing one or more barb members that partially embeds itself into a portion of the inside wall of the associated end tab or tabs of a picket cap the clip is installed on, for preventing removal or dislodgement of the clip from the end tab or tabs of the associated picket cap. The front face of the clip is in one embodiment of the invention can be shorter or longer than the backface of the clip, and has a front lip portion bent away from the clip body at an angle sufficient for having the bent lip portion act as a barb for partially penetrating into an associated inside wall of a profile into which the associated end tab of a picket cap is installed or pushed into. The barb-like lip of the front face of the clip extends across the full width of the front face, and prevents the picket cap once installed in the open end of a profile from being removed from the profile. Accordingly, in one embodiment of the invention, with the inventive clips installed on opposing end tabs of a picket cap, once the associated cap is installed on the end of a profile, it will become securely attached thereto, thereby enhancing the reliability and durability of the associated picket fence.




In a second embodiment of the invention, the above-described U-shaped clips may instead of a front lip portion, include one or more teeth bent away from the clip body at an angle sufficient for having the teeth portion act as a barb for preventing movement of the corresponding mated component parts, i.e., the picket cap and the profile fence.




In another embodiment of the invention, the U-shaped clips of the invention may be conveniently installed on an edge portion of a top opening of a profile of a fence post with the partial cut-out portion on the backside of the clip projecting upwardly for providing a barb member that partially penetrates into an associated inside wall of the profile. The barb-like lip or teeth of the front face of the clip extends along the width of the front face, and prevents a post cap configured to fit over and around the top opening of the profile from being removed therefrom. The barb-like lip or teeth of the clip embeds itself into the inside surface of the installed post cap. Accordingly, with the inventive clips installed on the edge portion of the open end of the profile, the post cap will become securely attached to the profile, thus enhancing the reliability and durability of the associated picket fence.

DETAILED DESCRIPTION OF THE INVENTION




In

FIG. 1

, a portion of a picket fence fabricated from plastic or similar material is shown. The fence includes a post cap


2


secured to the top of a post


4


, with a horizontal profile


6


secured to an upper inside side portion of the post


4


, as shown. A plurality of vertical profiles are rigidly secured to the horizontal profile and spaced apart juxta-positioned to one another, as shown. Two of the vertical profiles


8


shown have picket caps


10


secured to their top portions. One of the vertical profiles


8


as shown just before assembly with a picket cap


10


that includes opposing end tabs


12


having clips


16


, respectively, secured thereto, and spaced apart side tabs


18


, as shown. As will be explained in greater detail below, after the picket cap


10


has its end tabs


12


and side tabs


18


pushed into an opening in the top of the associated vertical profile


8


, through use of the inventive clips


16


the picket cap


10


will be installed to the associated vertical profile


8


.




In the exploded assembly diagram of

FIG. 2

, clips


16


are shown just prior to being pushed onto opposing end tabs


12


of a picket cap


10


. This is more clearly shown in the pictorial view of FIG.


3


. The pictorial view of

FIG. 4

shows the clips


16


installed on the opposing end tabs


12


of the associated picket cap


10


.




The side elevational view of

FIG. 5

shows a clip


16


of the present invention as installed on an end tab


12


of the associated picket cap


10


. The cross sectional view of

FIG. 6

taken along

of

FIG. 5

shows securement features of the clip


16


for retaining it on an associated end tab


12


, once installed thereon. The enlarged view of area A, as shown in

FIG. 7

, more clearly shows that the clip


16


includes a partially cutout portion for permitting the formation of at least one barb


20


by pushing the partially cutout portion of the clip material inward. Juxtaposed cutout portions can also be provided for forming a number of barbs


20


. The barb(s)


20


tends to dig into or protrude partly into the material of the associated end tab


12


, and will even more rigorously dig into the material if an attempt is made to pull the associated clip


16


off of the end tab


12


. The clip


16


also includes a lip portion at the top of the front face that is bent away from the clip for forming a front face barb


22


to prevent the associated picket cap


10


from being pulled away from the top of a vertical profile


8


once installed therein, as will be described in greater detail below. An example of dimensions in inches or portions of an inch for a typical clip


16


are shown in

FIG. 8

, along with the bend angles of the back face barb(s)


20


, and front face barb


22


. It should be noted that the dimensions are given for purposes of illustration only, and are not meant to be limiting. The clip


16


can be dimensioned as required for accommodating the dimensions of any particular fence and associated picket caps.




In

FIG. 9

, a front elevational view of the clip


16


of

FIG. 8

is shown.

FIG. 10

shows a back elevational view of the clip


16


, and

FIG. 11

a pictorial view thereof. Note the partially cut through portions


24


on the back face of the clip


16


for providing the barb(s)


20


which is formed by bending the partially cutout portion along with fold line


25


to protrude into the interior clip


16


. Also as clearly illustrated, the front face barb


22


is formed by a top lip of the front face of clip


16


that is bent away from the interior portion of the clip


16


, as shown.





FIG. 12

shows a pictorial view of a portion of a picket fence. As shown in this embodiment, the vertical profiles


8


include a hollow top portion


26


that in this example is rectangular in shape, for receiving the bottom portion of a picket cap


10


. As shown, for the centermost vertical profile, a picket cap


10


with clips


16


installed on opposing end tabs


12


is positioned for being pushed into the open end


26


of a vertical profile


8


for securement of the picket cap


10


thereto. Note that the side tabs


18


are designed for frictionally engaging inside surfaces of the front and back portions of the associated vertical profile


8


to centralize/align the cap


10


to the profile


8


.




Referring to

FIGS. 13

to


15


, a second embodiment of a picket clip


30


is shown in various views. The clip


30


is similar to the clip


16


of the first embodiment of the invention, in all respects except for the configuration of the front face barb-like projections. The clip


30


further comprises a pair of teeth


32


extending from the top of the front face that is bent away at an angle sufficient to form the barb-like projections as best shown in FIG.


15


. The clip


30


includes a partially cut-out portion for permitting the formation of a barb(s)


20


by pushing the partially cutout portion(s) of the clip material inward. The barb(s)


20


tends to dig into or protrude partly into the material of the associated component part, and will even more rigorously dig into the material if an attempt is made to pull the associated clip


30


off of the mounted part. The teeth


32


at the top of the front face are bent away from the clip


30


to prevent the associated picket cap


10


from being pulled away from the top of a vertical profile


8


once installed therein, as will be described in greater detail below.




In the exploded assembly diagrams of

FIGS. 16 and 17

, the clips


30


are shown just prior and after, respectively, to being pushed onto opposing end tabs with the teeth


32


oriented outward from the end tabs


12


.





FIG. 18

shows a pictorial view of a portion of a picket fence. As shown in this embodiment, the vertical profiles


8


include a hollow top portion


26


that in this example is rectangular in shape, for receiving the bottom portion of a picket cap


10


. As shown, for the centermost vertical profile, the picket cap


10


with clips


30


installed on opposing end tabs


12


is positioned for being pushed into the open end


26


of a vertical profile


8


for securement of the picket cap


10


thereto. Note that the side tabs


18


are designed to frictionally engaging the inside surfaces of the front and back portions of the associated vertical profile


8


to centralize and align the cap


10


to the profile


8


. Once installed, the teeth


32


are strongly biased against the inside surface of the associated vertical profile


8


and sharply dig into the material of the vertical profile


8


for effective and secure retainment therein. Concurrently, the barb


20


on the back face portion of the clip


30


is biased strongly against the inside surface of the end tab


12


for retainment the picket cap


10


in the vertical profile


8


.




With reference to

FIG. 19

, a partial pictorial view of the-fence post


4


and the post cap


2


is shown using the clips


30


of the present invention. It is noted that the clips


16


may also be used for fence assemblies of this configuration. In this fence configuration, the post cap


2


is configured to be mounted over the open end


26


of the fence post


4


. The post cap


2


includes a rim portion


34


which fits around the outer surface proximate the open end


26


. One or more clips


30


are mounted to edge portions


36


at the top of the open end


26


, preferably near the corner portions. The barb(s)


20


is biased against the inside surface of the fence post


4


, and the teeth


32


extends outward and downwardly on the outer surface of the fence post


4


.




The post cap


2


is mounted over the open end


26


where the teeth


32


of each clip


30


contacts and digs into the inside surface of the rim portion


34


of the post cap


2


for secure retainment thereon. Once the post cap


2


is fully mounted, the clips


30


are hidden under the post cap


2


. Again, it is noted that clips


16


may be use here in a similar fashion and positioned so that the front face barb


22


is located on the outer side of the fence post


4


. The technique is also applicable where the vertical profile


8


and the picket cap


10


are similarly configured to have the picket cap


10


to be mounted over the open end


26


of the vertical profile


8


.




Although various embodiments of the invention have been shown and described, they are not meant to be limiting. Those of skill in the art may recognize certain modifications to these embodiments, which modifications are meant to be covered by the spirit and scope of the appended claims. For example, the vertical profiles


8


or


4


of the fence can be configured to be other than rectangular, such as square, round, or rectangular, for example. The design of the picket cap


10


and post cap


2


will vary in accordance with the design of the associated profiles, with the design being modified in a manner for permitting the clip


16


and


30


to permanently secure the picket cap


10


and post cap


2


to the associated vertical profiles


8


and


4


, respectively, as previously described. Also, the clip


16


and


30


in a preferred embodiment of the invention consists of stainless steel, but can be made from any other suitable material. In addition, the clip


16


and


30


may also be installed on the side tabs


18


of a picket cap


10


in addition to being installed on the end tabs


12


, or in some combination thereof. Also, although vertical profiles


8


are illustrated, the invention is also applicable for use with horizontal profiles, or profiles at an angle.
