- Each of the frame assemblies 21, 22, 23 and 24 are formed of angularly related runs of .tubular pipe stock the ends of which are adapted to be telescopically connected and fixedly bolted together by the purchaser so the parts may be boxed and shipped in knocked down form to conserve shipping space and minimize shipping and handling costs.
- These various units may be selectively dimensioned to serve the needs of children of preschool age or older. In either case the construction of the overall structure as well as the respective frame assemblies will be identical except for pipe stock sizes and dimensions, larger and heavier pipe stock being used in the larger size units to assure adequate strength and safety.
- slide board approach platform 26 and table and bench seat platforms 27 and 28 may be variously constructed
- the present invention contemplates a novel construction which may be preassembled without the need of separable fastener elements for unitary installation. While this novel platform structure is here shown for use in providing slide approach platform 26, table platform 27 and bench seat platform 28, it is to be understood that the construction is of general utility and may be employed to form platforms adapted for any desired use.
- the platform construction may be employed to form seats and foot platforms for home yard and porch gliders, for bench seats designed for general use, and for picnic and table structures of general utility.
- each platform comprises a pair of identical platform support channels 131 and a pair of platform channels 132, which, in the case larger surface'areas or abutting surface areas are desired, can be multiplied as desired.
- each support channel comprises a channel member of a preselected length comprising a pair of spaced flanges 133 and 134 interconnected along adjacently related sides by an integrally formed web 135 through drilled at 136 adjacent the opposite ends adapting support channel 131 for bolted connection at 38 (FIG. 1) to frame runs 36, 79 in the case of platforms 27 and 28 and to runs 53, 62 and the slide board hand and support rails 137 in the case of platform 26.
- Through drilled openings 136 will be omitted, of course, in cases where such a bolted connection is not required or will be relocated in other selected locations along web 135 where a different bolted connection is required.
- flanges 133 and 134 terminate in vertically spaced aligned relation and are respectively provided with an intumed, slightly spaced, return bent lip 138 and an intumed rolled lip 139.
- Rolled lip 139 is suitably notched at longitudinally spaced intervals as indicated at 141 or a double width notch as indicated at 142 in place of the two inner notches 141 for a purpose to be presently pointed out.
- platform channels 132 each comprise a channel member of a preselected length comprising a pair of spaced flanges 143 and' 144 interconnected by a wide web 145 the center areas of which may, if desired, be embossed as indicated at 146.
- the free ends of flanges 143 and 144 are provided with an intumed, slightly spaced, return bent lip 147 the thickness and spacing of which is designed together with the thickness of the respective flanges to freely fit within the notches 141 of support channels 131. as shown in FIG. 3 with the outer flange faces lightly abutting the opposing notch edges thereby fixing the platform channels against lateral shifting movement relative to support channels 131.
- a pair of platform channels 132 having respectively wider webs 145 would be selected so the adjacently related faces of flanges 143 and 144 could be face butted in notch 142 as shown in dot-dash lines in FIG. 3.
- Webs 145 at laterally spaced points inwardly from their opposite ends are likewise button punched as indicated at 148 to form upstanding interlock formations providing an upwardly semispherical wall facing toward the respective opposite ends of web 145 and a diametrically laterally disposed abutment edge 149 facing toward the center of webs 145.
- buttons punched interlock formations 148 are preselected so that the axial distance of abutment edges 149 inwardly from the adjacently related ends of webs 143 will approximate but not exceed the distance between the inner face of webs and the intumed free edge of lips 138 of support channels 131.
- the upper ends of the return bent runs 152 of hand rails 137 arethen through bolted as shown at 38 in FIG. 1 to frame runs 53 and 62 in vertically spaced crossing relation above platform 26 while the lower ends of straight runs 153 of hand rails 137 are through bolted to frame runs 53 and 62 in cross relation at 38 using the same bolt and nut assemblies used to secure the telescoped ends of runs 53 and 62 to the upstanding legs of the adjacent frame corner members 54 and adjacent U-shaped member 61.
- the lower end of slide board 29 is supported in spaced relation to the ground or other support surface by a U-shaped support member 154 the upper leg ends of which are bent over and telescoped into the rolled slide board side rails.
- support channels 131 are preferably fitted with triangularly shaped, plastic, p'rotective cups 159 the walls 161 of which are through drilled at 162 to align with passages 136 of support channels 131 adapting the caps to be fixed in place with walls 161 clamped between the channel webs and the opposing frame runs to which they are bolted. Similar protection is provided for the free ends of crossing tubular runs by cylindrical plastic cup members 163 (FIG. 1).
- a platform assembly for use in forming table tops, bench seats, stand plafi'orms and the like without the need of separable fasteners comprising a pair of support channels the respective side flanges of which along their free longitudinal edges are provided with integral, inwardly disposed, return bent flange-like lips, one of which is spaced from its supporting flange and the other of which is provided at preselected longitudinally spaced intervals with through notches; and at least one platform channel having:
- a. dependent side flanges spaced and dimensioned to permit forced entry of the opposite ends of said platform channel between said one flange-like lip of the opposing side flange of said pair of support channels when said dependent side flanges are aligned with the through notches of said other flangelike lip of said support channels; and a flange connecting web provided adjacent its opposite ends with upstanding button punch protuberances arranged with their curved walls disposed toward said respective web ends and their abutment faces spaced inwardly from the respective web ends a distance equal to the spacing of the free edge of said one flange-like lip from the web of said respective support channels, whereby upon forceful insertion of said platform channel ends into said support channels said button punch protuberances will deflect said one flange-like lip toward its associated supporting flange during insertion and release said one flange-like lip, upon full insertion to dispose said button punch abutment faces beyond the free lip edge, to return toward its initial non-deflected position into opposing relation to
