FIG. 2D shows a top, rear, and left side closeup view of part of the locking strip 10.
The locking strip 10 includes top surface 12, rear surface 14, left edge 16, right edge 18, first end 10 a, and second opposing end 10 b. The locking strip 10 also includes a plurality of openings 20, which includes opening 20 a. Each of the openings 20, including opening 20 a may be identical and therefore only opening 20 a will be described in detail. Opening 20 a includes top semicircular portion 26 a, a central rectangular portion 24 a, and a bottom portion 22 a. The top portion 26 a may have a diameter D5, which may be about one quarter of an inch. The central portion 24 a may have a length L4 of about one and one quarter inches, and a width W4 which may be about three quarters of an inch. The width W4 of the rectangular section 24 a is preferably less than the width W6 of the picket 30, shown in FIG. 3D. These dimensions enable and/or assist in locking the picket 30 in place in the with the locking strip 10. The portion 22 a has a width W5 which may be shown in FIG. 2C which may be about one inch or about the side length L1 of each of the openings 8 of the rail 1 shown in FIG. 1C. The bottom portion 22 a may have a length L3 which may be one and one quarter inches. The bottom portion 22 a, in at least one embodiment is at least as large as each of the openings 8 of the rail 1, to allow picket 30 shown in FIG. 3A to pass through both the bottom portion 22 a of the locking strip 10, and the opening 8 of the rail 1 as shown for example by FIGS. 5C, 5D, 6B, and 7A.
The slots 40 and 42 may have a dimension L7 along the length of the picket 30, shown in FIG. 3D, which may be substantially less than the width D6 of the picket 30 and the slots 40 and 42. For example the length L7 may be one half or less than one half of the width W6.
The locking strip 10 may be replaced by a locking strip similar or identical to locking strip 260 having square or substantially square openings 264, 266, and 268, as shown in FIG. 12, and the locking strip may have any number of square openings analogous to opening 264.
There is a distance D2, which may be two inches, between each pair of the plurality of openings 20. The uniform distance D2 is used to allow the bottom openings of the openings 20 (such as bottom opening 22 a of the opening 20 a, and corresponding bottom openings for other openings of 20 b-20 k) to be aligned with the openings 8 of the rail 8. I.e. bottom openings of openings 20 a-20 j shown in FIG. 2A are configured so that they can be aligned with openings 8 a-8 j, respectively, of rail 1 of FIG. 1. The bottom openings of 20 b-20 k could also be aligned with openings 8 a-8 j, respectively or rail 1 or if the locking strip is turned upside down, openings 20 k-20 b could be aligned with 8 a-8 j or openings 20 j-20 a could be aligned with openings 8 a-8 j, respectively.
The locking strip 10 may be made of hard plastic or metal or any other material shaped in locking strip fashion.
FIG. 3A shows a top, front, and right side perspective view of a vertical member or picket 30 for use with the rail 1 of FIG. 1A and the locking strip 10 of FIG. 2A. FIG. 3B shows a top, rear, and left side perspective view of the vertical member or picket 30. FIG. 3C shows a top, front, and right side perspective closeup view of part of the vertical member or picket 30 for use with the rail 1 and the locking strip 10. FIG. 3D shows a top, rear, and left side perspective closeup view of part of the vertical member or picket 30.
The vertical member or picket 30 includes sides or walls 32, 34, 36, and 38. The picket 30 may be substantially in the form of a rectangular tube. However, the picket 30 may be, or may be replaced by a round picket, or solid picket, as long has typically the picket has notches or slots similar or identical to notches or slots 40 and 42.
The picket 30 has openings 44 a and 44 b at ends 31 a and 31 b respectively. The openings 44 a and 44 b lead to inner chamber 46 which is enclosed or substantially enclosed by walls 32, 34, 36, and 38. The picket 30 has slots 40 and 42. The slots 40 and 42 cut through the entire wall 36, and through about half of each of walls 38 and 34, in at least one embodiment. The slots 40 a and 42 allow access to the inner chamber 46.
The picket 30 may be square hollow tube or a substantially square hollow tube, with the exception of slots 40 and 42, and the picket 30 may have a width W6 which is about one inch and which is slightly less than the length L1 of each of the openings 8 a-8 j of the rail 1 shown in FIG. 1A. This allows the picket 30 to be inserted into any one of the openings 8 a-8 j of the rail 1 as shown in FIGS. 5C-5D, and 6B. The picket 30 may be made of a hard material, such as aluminum, steel, plastic, or composite.

In addition, in FIG. 5B, the locking strip 10 has been slid into a position in which the bottom portions (analogous to bottom portion 22 a of opening 20 a) of openings 20 k-20 a are aligned with the openings 8 a-8 j respectively. The arrangement of FIG. 5B allows the picket 30 to be inserted through any of the aligned combinations of openings 20 k-a and 8 a-j, respectively.
FIG. 5C shows a front view of the horizontal member or rail 1 and a rear view of the locking strip 10, and a top view of a plurality of a pickets 30 a-j, each identical to the picket 30, with the locking strip 10 inserted into the rail 1, and the plurality of pickets 30 a-j inserted into openings 8 a-j, respectively of the rail 1 and openings 20 k-20 a, respectively of the locking strip 10, with the locking strip 10 in a first state, in which the portion 22 a of opening 20 a (and the analogous portions of openings 20 b-20 j) are aligned with the openings 8 j-8 a.
FIG. 5D shows a front view of the horizontal member or rail 1 of FIG. 1A, a rear view of the locking strip 10 and a top view of a plurality of pickets 30 a-j identical to the picket 30 of FIG. 3A, with the locking strip 10 inserted into the rail 1 of FIG. 1A, and the plurality of pickets 30 a-j inserted into the openings 8 a-8 j of the rail 1 and the openings 20 k-20 a of the locking strip 10, respectively and with the locking strip 10 in a second state, in which the locking strip 10 has been slid up in the direction U1 shown in FIG. 5D, with respect to the rail 1. In FIG. 5D, the portion 24 a shown in FIG. 2C of the opening 20 a is now aligned with the opening 8 j of the rail 1. Analogously the corresponding portions of the openings 20 b-20 k are now aligned with the openings 8 i-8 a of the rail 1. The slots 40 and 42 of the picket 30 allow the solid portion, flange, or protrusion 28 a shown in FIG. 2C to move into the slots 40 and 42 of the picket, and of the analogous slots of pickets 30 a-j. This permits the locking strip 10 to move into the second state or locking state. When the locking strip 10 is in the locking state of FIG. 5D with respect to the pickets 30 a-j, the pickets 30 a-j cannot be removed from the openings 8 a-j of the rail 8, because they are prevented by the protrusion, flange or solid portion 28 a shown in FIG. 2C.
FIG. 6A shows a top, rear, and left side view of the plurality of pickets 30 a-j, each identical to the picket 30 of FIG. 3A and a bottom, rear, and right side view of the rail 1 of FIG. 1A, with the locking strip 10 inserted into the rail 1, and the locking strip in a first state. FIG. 6B shows a top, rear, and left side view of a plurality of pickets 30 a-j, each identical to the picket 30 of FIG. 3A and a bottom, rear, and right side view of the rail 1 of FIG. 1A, and the locking strip 10 of FIG. 2A inserted into the rail 1, and with the locking strip 10 in a second state, and with the plurality of pickets 30 a-j inserted into the rail 1. In the second state, as in FIG. 5D, the locking strip 10 has been slid up in the direction U1, so that the pickets 30 a-j cannot be moved out of the rail 1 in the directions D7 or D8, due to portion 28 a of opening 20 a and analogous portions or openings 20 b-20 k, which sit in slots 40 a-40 j, shown in FIG. 6A (each of which may be identical or analogous to slot 40 of picket 30).
FIG. 7 shows a perspective view of the plurality of pickets 30 a-j shown in FIG. 6B connected to the rail 1 of FIG. 1A, and an identical rail 101 to form a fence section. The locking strip 10 is shown inserted into the rail 1 and in a locked position in FIG. 7, as in FIG. 6B. A locking strip 110, identical to the locking strip 10, is shown inserted into the rail 101 in FIG. 7, in a manner similar to or identical to the manner in which locking strip 10 is inserted into rail 1. The ends of the pickets 30 a-j near slots 42 a-j shown in FIG. 6A are inserted into opening of rail 101 in a manner similar or identical to the manner in which ends of pickets 30 a-j near slots 40 a-j are inserted into openings of rail 1. After the particular end of pickets 30 a-j is placed through the particular opening of rail 1 or 101 and through locking strip 10 or 110, similar or identical to as shown in FIG. 8A, then the locking strip 10 or 110 is slid into a locking position similar or identical to that shown in FIG. 8B. In this manner the pickets 30 a-j shown in FIG. 7 are locked into position with respect to the rails 1 and 101 by use of locking strips 10 and 110.
FIG. 8A shows a top, rear, and left side closeup view of the picket 30 of FIG. 3A inserted into the locking strip 10 of FIG. 2A, with the locking strip 10 in a first state, such that the picket 30 goes through the portion 22 a of the opening 20 a. In the state of FIG. 7A, the picket 30 can be removed from the locking strip 10 because the opening 22 a is large enough to allow the picket 30 to be removed in the directions D7 or D8. This also occurs in the configuration of FIG. 6A, since the openings 8 a-8 j of rail 1 are also large enough to allow movement of the pickets 30 a-30 j.
FIG. 8B shows a top, rear, and left side closeup view of a picket 30 of FIG. 3A inserted into the locking strip 10, with the locking strip 10 in a second state, in which the portion 28 a of the locking strip 10 is inside of the slot 40. The portion 28 a prevents the picket 30 from moving in the directions D7 and/or D8 in the configuration of FIG. 8B. This also occurs for the pickets 30 a-30 j in the configuration of FIG. 6B, i.e. pickets 30 a-30 j cannot move in the directions D7 and/or D8 due to portions analogous to portion 28 a in slots 40 a-40 j, unless the locking strip 10 is slid back down in the direction D6.
One or more rails, locking strips, and pickets, identical or analogous to rail 1, locking strip 10, and picket 30 may be used in a method for assembling fence, railing, window guards and or any other structure constructed using horizontal and vertical members, in accordance with one or more embodiments of the present invention.
The inner rails or protrusions 6 c, 6 a, 2 c, and 2 a, serve to strengthen the rail 1. The inner rails 6 c and 2 c define a channel and/or cavity along with wall 4 for locking strip 10 to pass through. through to secure one or more vertical pickets, such as 30 a-j and one or more horizontal rails, which may be identical or analogous to rail 1, creating a finished product.
The locking strip will be specifically designed with an opening to allow the vertical picket to slide through and an adjacent lock feature to secure the vertical pickets and horizontal rails into place creating a finished product when engaged.
The locking strip has a depth L6, shown in FIG. 2C which may be about one eight of an inch and which is less than a channel width L5 shown in FIG. 1F, or distance between the wall 4 and the inner rails 2 c and 6 c; and this allows the locking strip 10 to be inserted into the channel between wall 4 and the combination of inner rails 6 c and 2 c, so that the locking strip 10 slides on the rails 6 c and 2 c as shown by FIG. 4B. The locking strip 10 has an overall width W7 shown in FIG. 2C which may be about one and three eighths inches which is slightly less than the distance between opposing walls 2 and 6 shown in FIG. 4B, to allow the locking strip 10 to slide in the channel between wall 4 and the combination or inner rails 2 c and 6 c, which being held up by the inner rails 2 c and 6 c.
In operation, in at least one embodiment, a plurality of horizontal rails, identical to rail 1, may be placed onto a flat surface, and a plurality of locking strips 10 may be slid up into the horizontal rail rib/cavity area or channel between wall 4 and inner rails 2 c and 6 c so that the holes 8 a-8 j on the horizontal metal rail 1 line up with the holes 20 j-a in the locking strip 10 as shown in FIG. 5C. A plurality of sets of pickets 30 a-j may then be slid through a plurality of sets of holes 8 a-8 j in the plurality of horizontal metal rails identical to rail 1 and also the holes 20 j-a, in the plurality of locking strips. Each of the plurality of locking strips, identical to 10, may be engaged by pulling it horizontally (shown as the direction U1 of FIG. 5D), to lock the plurality of sets of vertical pickets 30 a-j with the plurality of horizontal rails creating a finished product. Note that FIG. 6A shows rail 1 as vertical, but rail 1 would typically be horizontal, and the pickets 30 a-j would be perpendicular to the rail 1, and typically pickets 30 a-j would be vertical.

FIG. 16A shows a perspective view of the locking strip 240 of FIGS. 11A-11B and the rail 220 of FIGS. 10A-10B, separate from each other. FIG. 16B shows a perspective view of the locking strip 240 of FIGS. 11A-11B and the rail 220 of FIGS. 10A-10B, connected together in a non locked or open state. FIG. 16C shows a perspective view of the locking strip 240 of FIGS. 11A-11B and the rail 220 of FIGS. 10A-10B, connected together in a locked state.
FIG. 17A shows a perspective view of picket 330 a of FIG. 13 and the locking strip 260 of FIG. 12, separate from each other. FIG. 17B shows a perspective view of picket 330 a of FIG. 13 and a locking strip 260 of FIG. 12, connected together in a non locked or open state. FIG. 17C shows a perspective view of one of picket 220 a of FIG. 13 and the locking strip 260, connected together in a non locked or open state.
In operation, referring to FIG. 12, an end of locking strip 260 nearest the opening 264 can be inserted into the opening 228 of the rail 220 shown in FIG. 12. The locking strip 260 is inserted into the inner chamber 230 shown by FIGS. 10A-10D, so that the locking strip 260 lies flat, inside the inner chamber 230 on the protrusions or flanges 231 and 229, or on the ribs, protrusions or flanges 237 and 235 shown in FIGS. 10A, 10B, and 12, between the protrusions 231 and 229 (or protrusions 237 and 235) and the wall 224, and so that the openings 264, 266, and 268 of the locking strip 260 are aligned with the openings 225, 223, and 221, respectively, of the rail 220. When the locking strip 260 is inside the inner chamber 230 as described, with the openings 264, 266, and 268 aligned with the openings 225, 223, and 221, the locking strip 260 is in an unlocked state with respect the rail 220. The openings 264, 266, and 268 may be about the same size and shape as the openings 225, 223, and 221, respectively. Although shown as square shaped, the openings 264, 266, 268, 225, 223, and 221 may be another shape which would generally correspond to the shape of the pickets. In the example of FIG. 13, the pickets 330 a-330 c have a square cross section and therefore the openings 264, 266, 268 and 221, 223, and 225 generally would have a square cross section in that case.
Similarly, or identically, an end of locking strip 260 a nearest the opening 264 a can be inserted into the opening 228 a of the rail 220 a shown in FIG. 12. The locking strip 260 a is inserted into the inner chamber 230 a, so that the locking strip 260 a lies flat, inside the inner chamber 230 a on the protrusions or flanges 231 a and 229 a (or on the protrusions, flanges, or ribs 237 a and 235 a shown in FIG. 12, between the protrusions 231 a and 229 a (or 237 a and 235 a) and the wall 224 a, and so that the openings 264 a, 266 a, and 268 a of the locking strip 260 a are aligned with the openings 225 a, 223 a, and 221 a, respectively, of the rail 220 a. When the locking strip 260 a is inside the inner chamber 230 a as described, with the openings 264 a, 266 a, and 268 a aligned with the openings 225 a, 223 a, and 221 a, the locking strip 260 a is in an unlocked state with respect the rail 220 a. The openings 264 a, 266 a, and 268 a may be about the same size and shape as the openings 225 a, 223 a, and 221 a, respectively. Although shown as square shaped, other shapes are possible as previously described.
Next, the pickets 330 a-c may be inserted into the rails 220 and 220 a. Ends 331 a-c are inserted through the openings 264, 266, and 268 of the locking strip 260 and aligned openings 221, 223, and 225 of rail 220, respectively. Ends 332 a-c are inserted through the openings 264 a, 266 a, and 268 a of the locking strip 260 a and aligned openings 221 a, 223 a, and 225 a of rail 220 a, respectively. The ends 331 a-c and 332 a-c are inserted so that parts of the locking strips 260 and 260 a will be able to be slid into the slots 340 a-c and 342 a-c of the pickets 330 a-c, respectively, to lock the pickets 330 a-c in place so that they cannot move up in the direction U3 or down in the direction D13 as shown in FIG. 14B. FIG. 14A shows the pickets 330 a-c inserted into the rails 220 and 220 a with the locking strips 260 and 260 a in an unlocked state. To put the locking strips 260 and 260 a in a locked state, the locking strips 260 and 260 a are slid in a direction D9 from the state of FIG. 14A to the state of FIG. 14B. Sliding the locking strips 260 and 260 a in the direction D9 causes parts of the locking strips 260 and 260 a to be inserted into the slots 340 a-c and 342 a-c. For example, FIG. 17A shows picket 330 a. End 331 a of picket 330 a is inserted into the opening 264 of locking strip 260 (and through corresponding opening of rail 220 not shown in FIG. 17A). FIG. 17B shows the end 331 a inserted through the opening 264 until the slot 340 a is in a position where part of the locking strip 260 can slide into the slot 340 a. The locking strip 260 can then be slid in the direction D11 with respect to the picket 330 a until a substantial part of the locking strip 260 lies in the slot 340 a, so that the picket 330 a is prevented from moving, substantially up in the direction U3 or down in the direction D13 as shown in FIG. 17C. The picket 330 a is thus locked into position, unless and until the locking strip 260 is slid back in the direction opposite D11 with respect to the picket 330 a so that no part of the lock strip body portion 262 lies inside of the slot 340 a, as in FIG. 17B. In the unlocked state of FIG. 17B, the picket 330 a can be moved up in the direction U3 and down in the direction D13 in order to remove the picket 330 a from the locking strip 260 (and thus from the rail 220 not shown in FIGS. 17A-C).
The ends 332 a-c are inserted through the openings 221 a, 223 a, and 225 a of the rail 220 a and through the openings 264 a, 266 a, and 268 a of the locking strip 260 a in a similar or an identical manner as explained with reference to rail 220 and locking strip 260. The rail 220 a and locking strip 260 a is locked in place in a similar or identical manner with respect to pickets 330 a-c as rail 220 and locking strip 260.
Referring to FIG. 15A, after the pickets 330 a-c have been locked in place at both ends, next the ends of locking strips 240 and 240 a, nearest openings 246 and 246 a, respectively are inserted into the inner chambers 212 and 212 a, respectively of posts 201 and 201 a. The locking strip 240 is inserted into the inner chamber 212 of post 201 so that the locking strip 240 lies flat on the protrusions 216 and 218, and between the wall 208 and the protrusions 216 and 218, and so that the openings 244 and 246 of the locking strip 240 align with the openings 203 and 205, respectively, of the post 201. Similarly or identically, the locking strip 240 a is inserted into the inner chamber 212 a of post 201 a so that the locking strip 240 a lies flat on the protrusions 216 a and 218 a, and between the wall 208 a and the protrusions 216 a and 218 a, and so that the openings 244 a and 246 a of the locking strip 240 a align with the openings analogous to openings 203 and 205 for post 201 a, respectively, of the post 201 a.
After the locking strips 240 and 240 a have been inserted in the previously described manner in the posts 201 and 201 a, an end of the rail 220 is inserted into the opening 203, an opposing end of the rail 220 is inserted into an opening corresponding to 203 but for 201 a (not shown), an end of the rail 220 a is inserted into the opening 205 of the post 201, an opposing end of the rail 220 a is inserted into a corresponding opening to opening 205, but for post 201 a, not shown. The ends of the rails 220 and 220 a (along with the ends of locking strips 260 and 260 a) are also inserted through the appropriate openings of locking strips 240 and 240 a which are aligned with openings of the posts 201 and 201 a. For example, an end of rail 220 is inserted through opening 203 and through opening 244. An end of rail 220 a is inserted through opening 205 and opening 246. The opposing end of rail 220 is inserted through opening 244 a and opening of post 201 a corresponding to opening 203. The opposing end of rail 220 a is inserted through opening 246 a and opening of post 201 a corresponding to opening 205.
After the rails 220, 220 a, locking strips 260 and 260 a (not shown in FIG. 15C), posts 201 and 201 a, and locking strips 240 and 240 a have been assembled as in FIG. 15B, next the locking strips 240 and 240 a are pushed downwards in the direction D10 to lock the rails 220 and 220 a to the posts 201 and 201 a, in the locked position of FIG. 15C. In the locked position of FIG. 15C the rails 220 and 220 a cannot be moved substantially in the directions D9 or opposite D9, without moving the locking strips 240 and 240 a back upwards in the direction U3, with respect to the posts 201 and 201 a, to the position shown in FIG. 15D. In addition, the pickets 330 a-c cannot be moved substantially up in the direction U3 or down in the direction D13.
In operation, the rail 220 can be locked or engaged (within inner chamber 212 of post 201) by the locking strip 240 as shown by FIGS. 16A-C. The end of the rail 220 nearest slot 234 can be inserted into the opening 244 of the locking strip 240, as shown by FIGS. 16A-B. Next, the rail 220 can be moved upwards in the direction U2 so that part of the body portion 242 of the locking strip 240 will be inserted into the slot 244 of the rail 240.
