DETAILED DESCRIPTION OF THE INVENTION

(20) The Wall Module for a Modular Wall 1 of the present invention comprises a multitude of wall segments 2.

(21) These wall segments 2 adjoin or connect to one another to form, when viewed from above, a wall 1 which is either (1) a closed FIG. 3 such as a polygon or, preferably, a circle or a wall 1 the ends 4 of which do not join.

(22) When viewed from the front 5 (i.e., the portion of the wall segment 2 which faces outward, in the version where the wall 1 creates a closed FIG. 3) or viewed from the back 6 (i.e., the portion of the wall segment 2 which is directed inward when the wall 1 creates a closed FIG. 3), the wall segments 2 appears to be a rectangle. When viewed from the top 7 or the bottom 8, the wall segments 2 preferably appear to be an arc of a circle but optionally appear to be a rectangle.

(23) However, similarly to a wall segment 2 which appears to be an arc of a circle when viewed from above, the first end 9 and the second end 10 of a wall segment 2 which otherwise appears to be a rectangle when viewed from above, such first end 9 and, preferably, the second end 10 of at least one of two adjacent otherwise rectangular wall segments 2 must be angled with respect to one another, not parallel to one another, when such wall segments 2 are to be used to form a polygon that is not, itself, a rectangle.

(24) Near or on the first end 9 of a wall segment 2 and near or on the second end 10 of a wall segment 2 is a component 11 of a connector 12 so that multiple wall segments 2 can be connected to form the closed FIG. 3 or wall 1 the ends 4 of which are not joined, although when the ends 4 of the wall 1 are not joined, the first end 9 of the first wall segment 2 does not require a component 11 of a connector 12 and the second end 10 of the last wall segment 2 does not require a component 11 of a connector 12.

(25) The first component 13 of a connector 12 used for a closed FIG. 3 other than a rectangle will preferably be on a second end 10 of a wall segment 2, and the mating or second component 14 of the connector 12 will preferably be on the first end 9 of the adjacent wall segment 2. This will also be true for wall segments 2 forming a rectangle except for wall segments 2 which create a corner 15 of the rectangle.

(26) At any corner 15 of a rectangle there must, however, be a first component 13 of a connector 12 and a mating or second component 14 of a connector 12. And, preferably, the alternating pattern of first and second components 13, 14 of connectors 12 continues.

(27) When a rectangular closed figure has only four wall segments 2, though, the only other binding restraint is that for both wall segments 2 which are parallel to one another both components 11 of the connector 12 must be in the same type of location on the respective wall segment 2, i.e., either on the inward facing back 5 or on an end 9, 10, although the type of component 11 of a connector 12 (first 13 or mating 14) at any such location need not necessarily be identical for each parallel wall segment 2. See, e.g., Figure x through Figure y.*

(28) Preferably, the first component 13 of a connector 12 is a projection 13 (a male component 13); and the mating or second component 14 of a connector 12 is an aperture 14 (a female component 14). Even more preferably, the connector 12 is a tongue and groove connector 12 with the first component 13 of the connector 12, consequently, being a tongue 13 and with the mating or second component of the connector, consequently, being a groove 14. If desired, more than one connector 12 can be used to join adjacent wall segments 2. Most preferably, though, the first component 13 of the connector 12 is an elongate projection in at least twobut, preferably, threedirections such as an extended tongue of a tongue and groove connector and the second component 14 of the mating aperture 13 is an elongate aperture in at least twobut, preferably, threedirections such as an extended-groove 14 of a tongue and groove connector 12; indeed, the extended tongue 13 and an extended groove 14 are most preferably of such a size as to cause adjacent wall segments 2 to move substantially together in addition to aligning such wall segments 2 thereby enhancing the stability of a wall formed from such wall segments 2 and maintaining the integrity of such wall.

(29) When desired, the connection of the wall segments 2 can be reinforced by placing a supplemental fastener, preferably a screw (especially a self-tapping screw) or bolt through one or more of the front and back of the wall segment 2 and also through the tongue 13 of the tongue and groove connector 12.

(30) For a wall segment 2 which is intended for use with a trampoline, a channel 16 preferably exists along the length of each wall segment 2 at the top 7 of the back 6 of the wall segment 2 when such wall segment 2 is intended to be used in conjunction with a trampoline.

(31) Also preferably for a wall segment 2 which is intended to be used in conjunction with a trampoline the deepest portion 17 of the channel 16 has the same shape as the surface of a trampoline ring. As mentioned above, the channel 16 for use with a trampoline keeps the trampoline in better contact with the wall and thereby reduces the risk of a gap between the trampoline and the wall which could cause an injury to the user of the trampoline.

(32) And also a channel 16 intended to be used with a trampoline, preferably, has at least one depression 18, termed air vent depression 18 extending from the back 6 of the wall segment 2 to the top 7 of the wall segment 2 (to permit air forced down by a user landing on the trampoline to escape and then to permit air to be drawn back under the trampoline as the user is rebounded upward).

(33) In lieu of the above-described air vent depression 18, there are options for providing air venting, e.g., either (a) one or more apertures 22 in the back 6 of the wall segment below 2 the channel 16 and one or more apertures (not illustrated) in the top 7 of the wall segment 2 when the wall segment 2 is hollow (which is preferred) or (b) one or more tunnels (not illustrated) extending from the back 6 of the wall segment 2 to the top of the wall segment 2 when the wall segment 2 is solid.

(34) The wall segment 2 is composed of plastic, most preferably polyethylene, which can formed by rotational molding (which is also termed rotomolding) but can optionally be composed of wood, metal, or fiberglass or the like or any material known by a person of ordinary skill in the art to be acceptable.

(35) Also optionally, if a solid wall segment 2 is desired, it can be so formed from the preceding materials or a hollow wall segment 2 can be filled with any high-density foam which dries and is known to one of ordinary skill in the art to be acceptable.

(36) Even more preferably, as explained above, a segment of a trampoline ring 19 is situated in the channel 16 and is, preferably, attached to the top 20 of a leg 21 preferably composed of metal, which is preferably embedded in each such wall segment 2, although optionally some wall segments 2 do not contain the leg 21, and which can serve as a trampoline leg. Preferably, adjacent ring segments 19, which are preferably made of metal and which are preferably hollow, are connected to one another; also, preferably the adjacent ring segments 19 can be connected simultaneously or nearly simultaneously with the connection of the adjacent wall segments 2. Preferably, this is accomplished having a first end 22 of the ring segment 19 near, or most preferably, aligned with the first end 9 of the associated wall segment 2 and by having the second end 23 of the ring segment 19 extend beyond the second end 10 of the associated wall segment 2 and, having the diameter 24 of the second end 23 of the ring segment 19 decrease where the ring segment 19 passes the second end 10 of the associated wall segment 2 sufficiently to fit into the first end of the ring segment 19 associated with the next wall segment 2 with no gaps between the adjacent wall segments 2. However, any connector known to one of ordinary skill in the art can be utilized to connect the adjacent ring segments 19.

(37) For a wall segment 2 not intended to be used with a trampoline, there is not necessarily, but preferably, a channel 16; and, also preferably, an elongate member 25, which is preferably metal and is also preferably hollow, is connected to the top 7 of each wall segment 2. Moreover, preferably, the elongate members 25 for each wall segment 2 are connected to each other; also, preferably the adjacent elongate members 25 can be connected simultaneously or nearly simultaneously with the connection of the adjacent wall segments 2 just as described above for wall segments 2 associated with a trampoline, i.e., a second end 26 of the elongate member 25 would have a smaller cross section than the first end 27 of the elongate member 25 so that the second end 26 of one elongate member 25 could fit into the first end 27 of an adjacent elongate member 25. And the elongate member 25 for each wall segment 2 is, even more preferably, connected to the wall segment 2 by being connected to a leg 21, which is preferably embedded in the wall segment 2. Most preferably, the elongate members 25 of adjacent wall segments 2 can be connected with one another simultaneously or nearly simultaneously with the connection of the mating portions 13, 14 of the connectors 12 for the adjacent wall segments 2.

(38) As indicated above, the wall segments 2 are preferably hollow to decrease their weight; but the wall segments 2 also preferably have inward projections 28 from the interior 29 of the front 5 of the wall segment 2 touching inward projections 30 from the interior 31 of the back 6 of the wall segment 2 to increase the strength of the wall segments 2 while maintaining the light weight of the wall segments 2. Preferably, multiple conical projections 28 on the interior 29 of the front 5 of the wall segment 2 touch multiple semi-cylindrical projections 30 on the interior 31 of the back 6 of the wall segment 2 to increase the structural strength of the wall segment 2 while maintaining reduced weight for the wall segment 2.

(39) Preferably, the wall segments 2 used for any purpose each have a leg 20, as discussed above, embedded within them to increase stability and structural strength, whether the wall segment 2 is to be used with a trampoline or not. The leg 21 is attached to a ring segment 19 when the wall segment 2 is associated with a trampoline and connected to an elongate member 25 for a wall segment 2 not intended to be used with a trampoline. Inward projections 32 designated leg retainers 32 from the interior 29 of the front 5 of the wall segment 2 and from the interior 31 of the back 6 retain the imbedded leg 21 within the wall segment 2 thereby both increasing the strength of the wall segment 2 and maintaining the light weight of the wall segment 2. Furthermore, as does the channel 16 as described above, the leg 21 keeps a trampoline in better contact with the wall segment 2 and thereby reduces the risk of a gap between the trampoline and the wall 2 which could cause an injury to the user of the trampoline.

(40) Additionally, the end 33 of the leg retainers 32 away from the front 5 or back 6 of the wall segment 2 is shaped to accommodate the leg 21. Also, each leg retainer 32 is preferably hollow. The imbedded leg 21, therefore, both increases the strength of the wall segment 2 and maintains the light weight of the wall segment 2.

(41) Optionally. A planar plate 34 is attached at the bottom 35 of the leg 21 parallel to the bottom 8 of the wall segment 2.

(42) For a wall segment 2 which is intended to be buried in the ground with the top 7 of the wall segment 2 level with the ground, such as for use with a trampoline, a horizontal ledge 36 preferably extends outward from the top 7 front of the wall segment 2 along the length of the wall segment 2 to serve as a support, designated a mow strip 36, for a lawnmower or trimmer to care for grass adjacent to the wall segment 2 without damaging any portion of the trampoline or any other object near the back of the wall segment 2. This mow strip 36, furthermore and even if no grass is adjacent to the Modular Wall reduces the risk of having a potentially dangerous gap between the ground and the wall segment 2.

(43) The ring segments 19 for use with a trampoline include the apertures traditionally known in the art for connecting a spring from the jumping mat of the trampoline to the ring segments 19.

(44) Several options exist for using the Wall Modules to construct a Modular Wall associated with a trampoline and are discussed immediately below.

(45) The ring segments 19 must either be connected to each other or to the adjacent wall segment 2.

(46) If the ring segments 19 are connected to each other, then the wall segments 2 do not have to be connected together because the ring segments 19 won't be dislodged by an inward force or an outward rebound.

(47) But if the ring segments 19 aren't connected to each other, then each ring segment 19 must be connected to the adjacent wall segment 2; and the wall segments 2 must either be connected to each other or, for non-rectangular walls, the wall segments must be at least partially below ground and have their fronts 5 adjacent to the soil.

(48) Non-rectangular wall segments 2 (for polygons other than rectangles and for circles) cannot be separated from each other by an inward force when each wall segment is connected to the adjacent ring segment because the length of the back 6 (inside wall) of each such wall segment 2 is shorter than the length of the face 5 (outside wall) for that wall segment 2, similarly to the walls of a traditional igloo. Therefore, for every point along the ends of a wall segment 2, the ends 9, 10 of the adjacent segment 2 block any inward movement of the wall segment 2.

(49) A Modular Wall constructed with the Wall Modules can be built with the bottom 8 of the wall segments 2 on the ground, below the ground, or on a floor.

(50) A Modular Wall composed of eight Wall Modules for association with a trampoline can be can be assembled in three to four minutes and permits nesting (stacking) of the Wall Modules. By reversing the direction of every other Wall Module nesting can be accomplished even when the wall segments 2 incorporate a mow strip 36.

(51) Notably, the Modular Wall can be provided as a kit having the Wall Modules.

(52) As used herein, the term substantially indicates that one skilled in the art would consider the value modified by such terms to be within acceptable limits for the stated value. Also as used herein the term preferable or preferably means that a specified element or technique is more acceptable than another but not that such specified element or technique is a necessity.
