Flexible fence assembly
A fence assembly is made up of a plurality of fence sections. Each section is made up of panels with top, bottom and side edges and front and rear surfaces. Slots are spaced from and milled into the panels along one of the sets of edges. A pair of trim extends over and covers the set edges and each trim has projections that snap or slide into the front and rear slots. The fence sections are coupled pivotably to fence posts such that the panels may pivot, under force of wind, about either their top or bottom end. The panels are restored to generally vertical position by the force of gravity.
1. Field of the Invention
This invention relates to fencing such as the type that might be used in suburbs for enclosing one's property and, in particular, to a type of fence assembly that will allow for wind passage therethrough without sacrificing privacy.
2. Description of the Prior Art
Especially in areas where strong winds frequently occur, fence rigidity is required. Otherwise in a strong wind the fence will not be able to withstand the force of the wind and be knocked over. Even where the fences are rigid, a very strong wind can cause damage to the fence and as the fence ages even less force is required to damage the fence and blow it over.
SUMMARY OF THE INVENTIONAccordingly, an object of the invention is a fence that will allow passage of wind therethrough without sacrifice of privacy.
Another object is such a fence that is lightweight and extremely flexible in terms of dimensions and color selection.
Still another object is such a fence that is easy to install, remove, replace and store.
A further object of the invention is to enable a ‘snap-together’ assembly for a manufacturing cost reduction.
A still further object is to enable greater post spacing through the use of longer, corrugated fence panels or equivalent.
These and other objects, features and advantages are accomplished in accordance with the teachings of the present invention, one illustrative embodiment of which comprises a fence assembly made up of a plurality of fence sections. Each section is made up of panels with top, bottom and side edges and front and rear surfaces. Slots are spaced from and milled into the panels along one of the sets of edges. A pair of trim extends over and covers the set edges and each trim has projections that snap or slide into the front and rear slots. The fence sections are coupled pivotably to fence posts such that the panels may pivot, under force of wind, about either their top or bottom end. The panels are restored to generally vertical position by the force of gravity.
BRIEF DESCRIPTION OF THE DRAWINGOther objects, features and advantages of the present invention will be apparent from the following detailed description and accompany drawing, wherein:
Referring to
The posts 11 can be of any cross-section, e.g., round, square, rectangular, etc. and can be made of wood, steel, plastic, etc., so long as they are rigid.
Each panel 12 may be a complete sheet or, as illustrated, a plurality of joined-together sheets as, for example, like multiple sheets of vinyl house siding, and made in different lengths, widths and color, depending on the site and application.
Each panel 12 is provided with an extruded, upper 13 and lower 14 trim that extends over and covers the top and bottom edges of the panels 12. The trims are affixed to the panel, either by screwing or, when spring is provided to the trim, by snapping or sliding the trims onto the edges of the panel as will be explained hereafter. The trims 13,14 are of a flexible plastic material. In areas where strong winds frequently occur, the need for fence rigidity is required. The trims 13,14 provide rigidity as well to the panel. The trim is made of ABS, vinyl or equivalent. Optionally, the bottom trim 14 can be omitted.
The top trim 13 is also used in securing the panel 12 to the posts 11, but in a manner to allow, with the bottom part of the panel 12 unsecured, the panel to pivot about its top length.
With the panels 12 thus mounted, the fence assembly allows the left and right panels 12 to pivot under a wind's force and thus allow wind flow through the fence assembly 10A. When the wind subsides, gravitational forces, in this instance the weight of the panels 12, return the panels 12 to their normally vertical position.
The embodiment 10B depicted in
The embodiment 10C differs from the
Each main body or panel 12 may be a complete sheet or, as illustrated in
The sheets are mill-cut or notched, typically ⅛ inch deep along the top at 22 and bottom at 23, in both the front and back to form little lips for a snap-on assembly of the upper trim 13 and lower trim 14, rather than necessitating the use of screws to secure the trim to the siding.

The fence assembly designs of the present invention permit thinner flexible materials that can simplify manufacture and provide other advantages such as lightweight and quick interchangeable and removable fence sections and allows for easy storage.
The fence assembly of the present invention is light in construction and can be built at small cost. The top and bottom trims are identical until the pivoting pin slots are added. Both are made as an extrusion with any desired length. When subjected to wind pressure, the fence panels will pivot, relieving the fence assembly of the force of the wind and ensuing damage. Forceful winds passage can occur without the need for large openings and extra cost of heavier construction
The assembly is virtually maintenance-free.
There is extreme design flexibilty that enables custom made fences with a choice of height, width and color.
The fence assembly of the present invention minimizes assembly time and manpower requirements because each fence unit has only three ‘snap together’ components.
The assembly enables a maximum ‘wind thru’ area without fence panel removal.
The assembly uses gravity for automatic fence repositioning after any degree of wind passage.
Each panel is independently removable. No tools are required for installation or removal of panels and there is a ‘lock-down’ ability, when preferred.
When excessive fence lengths are desired with greater fence post spacing, presently marketed corrugated panels used for roofing can be used instead of house siding. The same ‘snap-together’ assembly method can be used or a ‘slide’ attachment of the panel and its trim. Only a wider trim is required with its attachment on each side, and the fence sheets horizontally positioned.
It should be obvious that changes, additions and omissions may be made in the details and arrangement of parts without departing from the spirit and scope of the invention as hereinafter claimed.
