[0025] Reinforcing structure 20 includes first longitudinal member 40, which forms a portion of first side 22. Reinforcing structure 20 includes second longitudinal member 50, which forms a portion of second side 24. A distance between first end 26 and second end 28 defines a length 25. First longitudinal member 40 and second longitudinal member 50 are separated from one another. A plurality of cross members 60, e.g., 60a-60f (FIG. 1) and 60g-60l (FIGS. 2, 3), that span therebetween. A distance between first longitudinal member 40 and second longitudinal member 50 defines a width 62 (FIG. 3). Each cross member has a first edge 64, and a second edge 66. In one embodiment, for example the embodiment of FIGS. 2 and 3, cross members 60 include outwardly extending tab portions designated generally 68. First tab portions 69a extend outwardly from first longitudinal member 40 and second tab portions 69b outwardly from second longitudinal member 50. In one embodiment, tab portions 68 define widened portions 71 (FIG. 2). The widened portions 71 are proximate to first edge 64 and proximate to second edge 66 of cross members 60 on tab portions 68.

[0026] In a preferred embodiment, cross members 60, first longitudinal member 40, and second longitudinal member 50 define a plurality of chambers 70.

[0027] In one embodiment, a portion of each of tab portion 69a that extends outside of first longitudinal member 40 and a portion of each tab portion 69b that extends outside of said second longitudinal member 50 by an amount that is between 20% and 30% of the distance between first edge 64 and second edge 66 of cross members 60. In one embodiment, reinforcing structure 20 is an extruded member. In one embodiment, reinforcing structure 20 is made of aluminum.

[0028] Fence panel 10 additionally includes panel structure 100 (FIGS. 1, 2). Panel structure 100 has first side 102, second side 104, first end 106, second end 108, first edge 110, and second edge 112. Panel structure 100 preferably surrounds reinforcing structure 20.

In an embodiment having a tongue and groove configuration, panel structure 100 defines a longitudinal distance 140 from outer surface 120 to inner wall 134.

[0029] In one embodiment, first longitudinal member 40 and second longitudinal member 50 of reinforcing structure 20 define a distance between first edge 30 and second edge 32 that is between 85% and 95% of longitudinal distance 140 of panel structure 100.

[0030] Although particular embodiments have been described herein, it will be appreciated that the invention is not limited thereto and that many modifications and additions thereto may be made within the scope of the invention. For example, various combinations of the features of the following dependent claims can be made with the features of the independent claims without departing from the scope of the present invention.

[0031] It is to be understood that the terms including, comprising, consisting and grammatical variants thereof do not preclude the addition of one or more components, features, steps, or integers or groups thereof and that the terms are to be construed as specifying components, features, steps or integers.

[0032] If the specification or claims refer to an additional element, that does not preclude there being more than one of the additional element.

[0033] It is to be understood that where the claims or specification refer to a or an element, such reference is not be construed that there is only one of that element.

[0034] It is to be understood that where the specification states that a component, feature, structure, or characteristic may, might, can or could be included, that particular component, feature, structure, or characteristic is not required to be included.

[0035] Methods of the present invention may be implemented by performing or completing manually, automatically, or a combination thereof, selected steps or tasks.

[0036] The term method may refer to manners, means, techniques and procedures for accomplishing a given task including, but not limited to, those manners, means, techniques and procedures either known to, or readily developed from known manners, means, techniques and procedures by practitioners of the art to which the invention belongs.

[0037] The term at least followed by a number is used herein to denote the start of a range beginning with that number (which may be a ranger having an upper limit or no upper limit, depending on the variable being defined). For example, at least 1 means 1 or more than 1. The term at most followed by a number is used herein to denote the end of a range ending with that number (which may be a range having 1 or 0 as its lower limit, or a range having no lower limit, depending upon the variable being defined). For example, at most 4 means 4 or less than 4, and at most 40% means 40% or less than 40%.

[0038] When, in this document, a range is given as (a first number) to (a second number) or (a first number)-(a second number), this means a range whose lower limit is the first number and whose upper limit is the second number. For example, 25 to 100 should be interpreted to mean a range whose lower limit is 25 and whose upper limit is 100. Additionally, it should be noted that where a range is given, every possible subrange or interval within that range is also specifically intended unless the context indicates to the contrary. For example, if the specification indicates a range of 25 to 100 such range is also intended to include subranges such as 26-100, 27-100, etc., 25-99, 25-98, etc., as well as any other possible combination of lower and upper values within the stated range, e.g., 33-47, 60-97, 41-45, 28-96, etc. Note that integer range values have been used in this paragraph for purposes of illustration only and decimal and fractional values (e.g., 46.7-91.3) should also be understood to be intended as possible subrange endpoints unless specifically excluded.

[0039] It should be noted that where reference is made herein to a method comprising two or more defined steps, the defined steps can be carried out in any order or simultaneously (except where context excludes that possibility), and the method can also include one or more other steps which are carried out before any of the defined steps, between two of the defined steps, or after all of the defined steps (except where context excludes that possibility).

[0040] Further, it should be noted that terms of approximation (e.g., about, substantially, approximately, etc.) are to be interpreted according to their ordinary and customary meanings as used in the associated art unless indicated otherwise herein. Absent a specific definition within this disclosure, and absent ordinary and customary usage in the associated art, such terms should be interpreted to be plus or minus 10% of the base value.

[0041] Thus, the present invention is well adapted to carry out the objects and attain the ends and advantages mentioned above as well as those inherent therein. While the inventive device has been described and illustrated herein by reference to certain preferred embodiments in relation to the drawings attached thereto, various changes and further modifications, apart from those shown or suggested herein, may be made therein by those of ordinary skill in the art, without departing from the spirit of the inventive concept the scope of which is to be determined by the following claims.
