Abstract
ABSTRACT OF THE DISCLOSURE
A playground device mounted on a heavy coil spring support, the lower end of which is fastened to a ground anchor which is a lightweight construction comprising a lower-most horizontal plate member adapted to be buried in a hole in the ground and a connecting means, preferably comprising a plurality of substantially vertical legs, connecting the plate member with an upper mounting member adapted to be located in the ground surface level and stabilized in this location by said hole being refilled with earth, the mount-ing member serving to rigidly hold the lower end of the support of the playground device.

Description
~49~333 This invention relates to a playground device and, in particular, a resilient rocking device comprising a seat mounted on the top of a heavy, vertically disposed coil spring, the lower end of which is rigidly secured at ground level to a base anchoring member. A child using such a device may cause it to rock resiliently in all horizontal directions, provided, of coursel that the lower end of the coil spring is immovably anchored to the ground by means of said anchoring member. The most common type of anchoring member is a heavy concrete tile, provided with holes for receiving fastening bolts for the firm holding of the lower coil spring end. Such an anchoring member is perfectly usable, but the requirements as to the provision of the said holes and the dimensions of the tile normally require the heavy tile to be provided by the manufacturer of the play-ground device itself and be shipped along with the device.
This of course gives rise to considerably increased shipping ` costs due to the dominating weight of the tile, despite its character of a very simple product. In many cases a firm initial ground anchoring may be achieved without the use of a heavy element, viz. by means of poles or ground spikes holding the support against the ground surface, but such arrangements tend to become loose when they have been in use for some time.
The present invention provides an improved .~

anchoring structure which does not comprise really heavy elements, so as to be easy to ship, and which is capable of offering a rigid and durable anchoring of the pla~ground device.
According to the present invention there is provided a playground device of the type carried on a heavy bendable coil spring support which, in use, is likely to be subjected to tilt-ing or displacement forces, said support being secured to base anchoring means for firmly anchoring the lower end of the support to the ground, characterized in that said base anchoring means comprise a lightweight mounting member for holding the lower end of the support generally in the ground surface level and provided with downwardly extending connectingmeans which at its lower end is secured to lightweight plate means which is mountable in a generally horizontal, subterranean position.
For anchoring a device according to the invention it is required to dig a hole large and deep enough to receive the said plate means at a depth corresponding to said mounting member being located approximately in the ground surface level, but once this is done and the hole is again filled with earth thus depos-ited on the top side of the buried plate means, the earth ; pressure on the plate means will ensure a firm and durable holding of the plate means and thereby of the entire anchoring structure. All parts of the anchoring structure may be produced as lightweight elements, including the said plate means, and ; they are, therefore, easily shippable. The material for holding the parts, viz., the earth as thrown back into the dug hole, ;~ need no adaption whatsoever in order to fulfil its holding function.

The device shown in Fig. 1 generally comprises a heavy coil spring 2, a seat structure 4 mounted rigidly on the top of the spring, and lower mounting means including a pair of inverted U-bolts 6 for anchoring the lower end of the spring in a rigid manner to a ground engaging holding arrangement such that the lower spring end is rigidly held approximately in the ground surface level, whereby a child sitting on the seat structure 4 may carry out resiliently rocking move-ments of the seat structure.
A conventional type of a ground engaging holding arrange-ment is a heavy concrete tile 8 as indicated in dot-and--~ dash lines, such tile having holes for receiving the ends of the U-bolts 6.

For mounting the playground device a hole is dug in the ground, large enough to receive the plate member 14 having a depth such that the mounting member 10 is located in or just underneath the ground level. The preassembled unit 2, 4, 6, 10, 12 and 14 is then placed with the plate member 14 resting on

As apparent from Figs. 2 and 3 the mounting member 10 is preferably an invexted cup shaped metal sheet member having a plane top side 16 and an annular, depending edge flange 18 having at four points a mounting hole 20 for receiving a fastening bolt 21 for the top end of the respec-tive leg members 12, these at their lower ends having an outwardly bent foot portion 22 with a hole 24 for receiving a fastening bolt for the bottom plate member 14.
Underneath the top portion 16 of the mounting member 10 is a cross member 23, the opposite end portions of which have holes for receiving the ends of the U-bolts 6 and sup-porting tightening nuts 26 therefor. The cross member ends are offset or backed by distance members 28 such that the central portion of the cross member 23 is spaced somewhat from the underside of the cup top portion 16. Each o~ the leg members 12 has an inwardly bent top portion 30, the outer end of which is receivable in the space between the central portion of the cross member 23 and the cup member top portion 16, as shown most clearly in Fig. 3, whereby the respective leg members 12 may be secured very firmly to the mounting member 10 by means of a single bolt 21 through the flange hole 20 and a corresponding hole in the leg member.
