Abstract
A unitary polymeric structure that is a lattice fence material. The lattice fence has a first extension at a first angle. At least fifty percent of the first extension overlies and the remaining percentage of the first extension merges with a predetermined portion of a second extension. The second extension is at a second angle distinct from the first angle.
Description
- The present invention relates to a unitary polymeric lattice structure.
- A lattice, according to Webster's dictionary, is defined as a framework or structure of wood or metal made by crossing lathes or other thin strips so as to form a network. Such wooden lattices are known to have a 100% offset between a first strip and a second strip that cross and overlay each other. Anyone who has a wooden lattice realizes that they are difficult to repair and maintain. Accordingly, the plastic industry has attempted to re-create these fence designs in a durable form.
- Applicant admits there are numerous embodiments of unitary polymeric lattice structures. Many of these embodiments are illustrated in the following list of references:

Instead, the cited references disclose polymeric lattice designs that have a unitary non-offset design, a unitary one-strip offset design, a unitary two-strip offset design, or a non-unitary off-set design. For the unitary designs, each unitary design has an offset of less than twenty percent (hereinafter “Low Offsets”).
- Therefore, these Low Offsets have not satisfied a serious long-felt need to have a unitary polymeric lattice structure that has a significant (greater than 50%) offset. Applicant is unaware of any entity presently making such a significant offset lattice structure. Accordingly, applicant has found a mold design that allows applicant to solve this long-felt need.
- FIG. 1 illustrates a top view of the present invention.
- FIG. 2 illustrates a cross-sectional view of FIG. 1 taken along the lines2-2.
- FIG. 3 is a top view of FIG. 2.
- FIG. 4 is an alternative embodiment of the present invention.
- FIG. 5 is an alternative embodiment of the present invention.
- A unitary polymeric lattice fence is the present invention. The lattice fence is a framework of at least one first extension and at least one second extension that appear to cross over each other at different angles so as to form a network of apertures between the extensions. The first and second extensions each have a length, a width, and a depth that are the same or distinct. At the juncture where the first and second extensions appear to cross over each other, at least 50% to 95% of the depth of each extension is exposed and the remaining portion of the depth of each extension is merged with the other extension.
- The present invention relates to a polymeric lattice fence illustrated in FIG. 1. The
polymeric lattice fence 10 is a unitary polymeric structure having a framework of at least onefirst extension 12 and at least onesecond extension 14. Thefirst extension 12 and thesecond extension 14 appear to cross over each other, at ajuncture area 16, so as to form a network ofapertures 18. - As illustrated in FIG. 2, the
first extension 12 has atop surface 20, abottom surface 22 and a width W1 atouter edges 23 of theextension 12; and thesecond extension 14 has atop surface 24, abottom surface 26, and a width W2 atouter edges 27 of theextension 14. In relation to thefirst extension 12, thebottom surface 22 does not extend beyond the halfway point of W2 toward thebottom surface 26. Likewise, thetop surface 24 does not extend beyond the halfway point of W1 toward thetop surface 20. That way, the first extension and the second extension has at least a 50% offset. - The fifty percent offset is merely the minimum offset of the present invention while the maximum offset of the present invention is limited to include 95% and below. Otherwise, the present invention would not be an unitary polymeric lattice structure.
- Under normal circumstances, it would be assumed that the maximum offset could be anything under 100%. Such a conclusion, however, ignores the fact that the polymeric lattice structure must remain unitary. Accordingly, applicant has discovered that there must be a merger at
area 16 wherein at least 5%, preferably 10%, of W1 at thefirst extension 12 and at least 5%, preferably 10%, of W2 at thesecond extension 14 must merge together. Otherwise, the plastic lattice structure will not remain unitary, under normal use. - The design illustrated in FIG. 1 is not limited to the angle (A) illustrated of the
first extension 12 and thesecond extension 14. The angle A illustrated in FIG. 1 is a right angle. Obviously, the angle A can be other angles, such as obtuse or acute, depending on the desired design. - In some instances, the offset should be greater than 80% and in others greater than 90%. In any case, the greater than 50% offset and less than 95% makes the present invention more realistic and simultaneously durable for conventional uses of lattice fencing.
- For sake of clarity, the
present invention 10 has a plurality of extensions that either parallel the first extension 12 (marked as extension 12A) or the second extension 14 (marked as extension 14A), and multiple cross areas (marked asareas 16B-I) similar to the area marked 16. Such markings clearly illustrate the various structures of thelattice design 10. - Alternatively, the width W1 can be the same or different as the width W2. Also,
area 16 is not mated, glued or joined together by any conventional matter other than when formed. - The
lattice unit 10 is formed by injecting melted polymeric resin, i.e., polyethylene, into a mold having the predetermined design of the present invention. - The polymeric resin used in the present invention must be able to withstand the summer heat and the winter cold, without extensive cracking or melting. In other words, the present invention must be able to withstand the conventional climate found at least within the continental United States.
- In FIG. 1 the
aperture 18 is illustrated as a square. That aperture design is not the only design. It can be any other design, such as a polygon like a rectangle, a diamond, or a pentagon, or shape having a continuous single curvilinear line like a circle as shown in FIG. 4, or an ellipse. When a shape having a continuous single curvilinear line is used, there is fill 80. Fill 80 can be the width of the merger W4 of the twoextensions first extension 12, the width W2 of thesecond extension 14, the width W3 of the first andsecond extensions second extensions extensions - The
extensions - Although variations in the embodiment of the present invention may not each realize all the advantages of the invention, certain features may become more important than others in various applications of the device. The invention, accordingly, should be understood to be limited only by the scope of the appended claims.
