Description
1~263V3 The present invention relates to playground equipment.
BACKGROUND OF :L'III~ INVENTION
Playground climbing equipment is usually formed of a combination of upright and horizontal members of various materials connected together to form a framework on which children may climb. In some such frameworks metal bars or tubes of circular cross section are fixed together in such a manner that it would be at least difficult or impracticable to disassemble it for frequent rearrangement. In other frameworks, for example, that disclosed in U.S. patent No. 3,814,416, provision is made for changing the configuration at will by the manner of engagement between horizontal members and uprights.
In this case, wooden uprights are provided with through-bores for horizontal rods and means are provided to stop the rods slipping in the bores. Such an arrangement suffers from the weight and expense of solid wood members of such a thickness to take throughbores without splitting.
Steel box type uprights are known for other uses.
SUMMARY OF TllE INVENTION
The present invention obviates many of the previous difficulties in that we provide, in playground equipment of the type comprising units having bores there-through and tubular members interfitting therewith through said bores; a unit comprising two metal angle bars secured qb ~26~
together at their ed(3es to form a angled tube, tubular inserts being provi<led thel~ throu~Jh in at least two cross-sectional planes secures to a surface of each bar of said 10unit and extellding throuc3h said surfaces to form a bore through said unit. ~referably, the bore is of circularcross-section, a suitable diameter for the bore being about 4cm. The angle bars may suitably be of steel and be connected together by welding.
The tubular inserts extending through the box column formed by the angle bars act to provide reinforcement to the tube.
The features and advantages of the invention will be more fully understood from the followed description and ¦ 20drawings in which:
Fig. 1 is a perspective sketch of one embodiment of playground equipment according to the invention, Fig. 2 is a perspective view from the corner of one upright unit of the equipment of Fig. 1, Fig. 3 is a plan view from above of the unit of Fig. 2, Fig. 4 is a view of a horizontal tubular insert of the unit of Fig. 2 and 3, Fig. S is a section on the line A-A of Fig. 6 10The play equipment shown in Fig. 1 comprises upright units 1 connected to form a free-standing structure by tubular members 2. Each unit 1 is formed of two L-shaped steel angle bars 3 which are welded together at inturned flanges 4 at weld points 5. The lengths of the arms of the L-shaped angle bars 3 may suitably be about 14cm, thus forming walls 9, 10, 11, 12 of the unit 1 so that the unit 1 has squar~ cross-section each side of which may ~e about 14cm.. There is however, no reason why units formed of angle bars of other dimensions should not be used.
Steel tubular inserts 6 extend between and through opposing walls 9 and 11 or 10 and 12 so that one end 7 of each insert 6 opens flush with the outer surface of unit 1 in; for example, wall 11 or wall 10-The other end 8 of each insert 6 protrudes from the opposing outer surface of unit 1 through, for example, wall 9 and wall 12. The tubular insert 6 is secured to the unit 1 by welding where it passes through opposing walls 9,11 or 10, 12.
A plurality of tubular inserts 6 are provided in each unit 1. ~ach alternate tubular insert 6 suitably extends between and through the same pair of walls for example wall 9 and wall 11 and each adjacent tubular insert 6 extends and between and through the other pair walls 10 and 12. ~lowever, this is not a necessary arrangement provided that at least one tubular insert 6 extends between and through each pair of opposing walls. It is desirable that for a single uni.t 1 the protruding ends 8 of the inserts 6 are distributed only over two of the walls, for example, walls 9 and 12 so that the other two walls 10 and 11 are free from proturberances and their surfaces can be butted directly against a corresponding surface of another unit in building playground equipment from the units. The unit 1 formed by welding together two angle bars 3 i.s strengthened in its structure by the provision of the inserts 6 each _ ~_ of which acts as an additional link anchoring the angle bars 3 together.
~ oth for the additional security of anchoriny the bars 3 together and for a suitable deyree of variability as to the manner of assembly of units ], an insert 6 between one pair of opposing walls, say 9 and 11 may be provided at 40cm intervals over the length of the unit is 240cm, an insert 6 is between walls 9 and 11 at 15cm from one end of unit, further inserts 6 are provided at 40cm intervals between walls 9 and 11, an insert 6 is between walls 10 and 12 at 25cm from said end of the unit and fùrther inserts 6 are provided between walls 10 and 12 at 40cm intervals.
Play equipment is assembled from the above described units by running horizontal tubular members 2 through the tubular inserts to build the equipment in any desired configuration, for, example that shown in Figure 1.
It can be seen that units 1 need not be all the same height, may lie with their clear sides directly abutting or with sides spaced apart. Units 1 can also be used horizontally as roofing or platform members. Tubular members 2 are usually horizontal to connect either vertical or horizontally used units 1, usefully forming vertical or horizontal ladders for play value. Elowever, tubular members 2 may also be vertically arranged form horizontal units 1.
To provide fixing of tubular members 2 within tubular inserts 6, each protruding end 8 of a tubular insert 6 is provided with releasable locking means 13 to stop the tubular member 2 sliding within insert 6 except 6~ 3 during assc~bly and/or disassembly. The locking means may suitably be a hole ]4 in ~nc~ 8 of insert 6 to co-operate with a plug or bolt 15 whicl- is removably insertable into the hole to press member 2 ayainst the inn~r wall of insert 6 to secure it against sliding. Suitably a screw threaded nut 16 is fixed to the outer surface of insert 6 at end 8 so that the hole of the nut 16 is ~ligned with and corresponds in size with hole 14~ Then bolt 15 may be correspondingly threaded to engage in nut 16, extend through hole 14 and bear against member 2. Alternately or additionally hole 14 may be screw threaded for engagement with screw threaded bolt 15. It will, of course be understood, that various modifications and changes may occur to those skilled in the art and it is intended that the claims be interpreted to cover such modifications and equivalents.

It is desirable that for a single uni.t 1 the protruding ends 8 of the inserts 6 are distributed only over two of the walls, for example, walls 9 and 12 so that the other two walls 10 and 11 are free from proturberances and their surfaces can be butted directly against a corresponding surface of another unit in building playground equipment from the units. The unit 1 formed by welding together two angle bars 3 i.s strengthened in its structure by the provision of the inserts 6 each _ ~_ of which acts as an additional link anchoring the angle bars 3 together.
~ oth for the additional security of anchoriny the bars 3 together and for a suitable deyree of variability as to the manner of assembly of units ], an insert 6 between one pair of opposing walls, say 9 and 11 may be provided at 40cm intervals over the length of the unit is 240cm, an insert 6 is between walls 9 and 11 at 15cm from one end of unit, further inserts 6 are provided at 40cm intervals between walls 9 and 11, an insert 6 is between walls 10 and 12 at 25cm from said end of the unit and fùrther inserts 6 are provided between walls 10 and 12 at 40cm intervals.
Play equipment is assembled from the above described units by running horizontal tubular members 2 through the tubular inserts to build the equipment in any desired configuration, for, example that shown in Figure 1.
It can be seen that units 1 need not be all the same height, may lie with their clear sides directly abutting or with sides spaced apart.

Elowever, tubular members 2 may also be vertically arranged form horizontal units 1.
To provide fixing of tubular members 2 within tubular inserts 6, each protruding end 8 of a tubular insert 6 is provided with releasable locking means 13 to stop the tubular member 2 sliding within insert 6 except 6~ 3 during assc~bly and/or disassembly. The locking means may suitably be a hole ]4 in ~nc~ 8 of insert 6 to co-operate with a plug or bolt 15 whicl- is removably insertable into the hole to press member 2 ayainst the inn~r wall of insert 6 to secure it against sliding. Suitably a screw threaded nut 16 is fixed to the outer surface of insert 6 at end 8 so that the hole of the nut 16 is ~ligned with and corresponds in size with hole 14~ Then bolt 15 may be correspondingly threaded to engage in nut 16, extend through hole 14 and bear against member 2. Alternately or additionally hole 14 may be screw threaded for engagement with screw threaded bolt 15. It will, of course be understood, that various modifications and changes may occur to those skilled in the art and it is intended that the claims be interpreted to cover such modifications and equivalents.
