Quick fence
A modular fence panel and assembly. The modular fence panel has upper and lower channels. Each channel has through apertures that are equally spaced apart on the channel. Each aperture has a locking cap inserted therein for engaging the vertical picket. The locking cap, once inserted into the aperture, locks itself to the aperture. The picket, which has a spring clip inside, locks itself to the locking cap after the picket is inserted into the aperture on the channel. The spring clip prevents the picket from being removed from the channel. During assembly, the channels are first connected to vertical posts at both ends, through a pivoting connector, and then the pickets are inserted through the aligned apertures on the channels. The pivoting connector allows movements in both vertical and horizontal directions to accommodate different requirements for the fence assembly.
The present invention relates generally to the field of fences and more particularly relates to modular fence panels and assemblies that can be quickly assembled.
ART BACKGROUNDWrought iron fences are well known in the home, gardening and commercial field. In addition to serving as a security barrier for an owner's property, the fences can be used as protective fencing around swimming pools and gardens. The conventional wrought iron fences are formed by welding metal rods to upper and lower rails to form panels. Panels are joined by welding or bolting to upright posts.
While the fences are sturdy for their intended purposes, they still present some problems. One problem is that the welded areas are susceptible to rusting, even with a painted cover, or with galvanized components. Rusting, or oxidation, eventually causes the welded area to lose its structural integrity. Also, as more and more homeowners take up doing their own home improvements, stores such as Home Depot would like to carry fences that are modular, and can be easily assembled by their customers without requiring any welding. Their rationale is two-fold: The modularity of the fence panels allows the stores to minimize the different sizes of panels they have to carry. Also, the ease of assembly allows the stores to reach a broader customer base, such as those homeowners who do their projects on weekends.
To form a complete barrier assembly, conventional fence panels need to be joined to the vertical posts at both ends. However, such assembly is quite limiting, because it typically is achieved by using a straight connector between the panel and the post. Such straight connector offers very little, if any, range of movement or adjustment between the post and the fence panel.
Therefore, it is desirable to provide a picket fence panel and assembly that is quick to assemble at the job site, without requiring any welding. It is also desirable to provide a picket fence panel and components that can provide a variety of height and angular arrangements for the users based on the requirements of the location.
SUMMARY OF THE INVENTIONA modular fence panel and assembly is disclosed. The modular fence panel has upper and lower channels. Each channel has through apertures that are equally spaced apart on the channel. Each aperture has a locking cap inserted therein for engaging the vertical picket. The locking cap, once inserted into the aperture, locks itself to the aperture. The picket, which has a spring clip inside, locks itself to the locking cap after the picket is inserted into the aperture on the channel. The spring clip prevents the picket from being removed from the channel. During assembly, the channels are first connected to vertical posts at both ends, through a pivoting connector. The pivoting connector allows movements in both vertical and horizontal directions to accommodate different requirements for the fence assembly. With the channels in place and apertures aligned, the pickets are then inserted through the aligned apertures on the channels.
BRIEF DESCRIPTION OF FIGURES
A modular fence panel and fence assembly is disclosed. Although specific embodiments of the present invention is described with reference to the drawings, it should be understood that such embodiments are merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the teaching of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.
Briefly described, the present invention is a modular picket fence panel, which can be easily assembled without the use of welding, screws, rivets or fasteners. In one embodiment of the present invention, the modular picket fence panel 10 may be assembled with a pair of horizontal upper channel 14 and horizontal lower channel 16, and several vertical, and spaced-apart pickets 12 as shown in
Referring to
It should be noted that the pickets may have a cross-sectional shape that is other than the typical four-sided shape. More specifically, the pickets may have a round, or oval, cross section, while the aperture 15 on the channel is also of a round shape. Alternately, a four-sided picket may work with a round aperture, provided that the locking cap 32 acts as an interface with a four-sided interior for the picket, and a round external shape for the aperture. With the use of the locking cap, the shapes of the pickets can take on any shape, and so can the aperture 15 on the channel. As such, more flexibility is offered to the manufactures and more selection is provided to the customers.
Since both the basic structures of the upper channel and lower channel are identical, only the upper channel 14 is further described herein below for illustrative purposes. Referring to FIGS. 3(a)-(d), a lock cap 32 is shown to be ready for insertion and placement into the aperture 15 on the channel 14. The locking cap 32 is preferably made of reinforced nylon material, with two sloped one-way locks 33 on opposite sidewalls and at least one aperture 34 on the sidewall (two apertures are shown in fathom lines in

To fully take advantage of the fact that the pickets are secured only to one, e.g. upper, channel, the fence assembly in accordance with the present invention may be assembled in a drastically different way from the conventional method. Since only the upper channel is secured to the pickets through the use of the locking caps, while the lower channel is not, a consumer can easily first connect both channels to the vertical posts at their two ends. Then, with the channels in place, the consumer can easily insert one picket at a time through the apertures on each channel. In contrast, a conventional fence is assembled by inserting the pickets first through the channels, which are then connected to the posts. The versatility now offered by the present invention allows the fences to be easily transported in their un-assembled component condition, instead of being transported as the assembled panels to the job site.
The present invention has been described in a considerable detail in order to comply with the patent laws by providing full public disclosure of at least one of its forms. However, such detailed description is not intended in any way to limit the broad features or principles of the present invention, or the scope of the patent to be granted. Therefore, the invention is to be limited only by the scope of the appended claims.
