8 Claims.

This invention relates to supporting apparatus for a swing or the like.

One object of my invention is to provide supporting apparatus for a swing that is sufficiently resilient to make the swinging motion unusually smooth, and the strain on the apparatus relatively light.

Another object is to provide such supporting apparatus that is very durable and will withstand unusually vigorous swinging action, even when several swings in simultaneous movement are supported thereby.

A further object is to provide such apparatus that will keep the swings in a relatively straight path while swinging, yet permit a free swinging movement in the desired direction.

The foregoing and other objects which will ap pear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative arrangement of parts such as is disclosed .by the drawings. The nature of the invention is such as to render it susceptible to various changes and modifications, and, therefore, I am not to be limited to the construction disclosed by the drawings nor to the particular parts described in the specification; but am entitled to all such changes therefrom as fall within the scope of my claims.

In the drawings:

Figure 1 is a side elevational View of my supporting apparatus with a swing suspended therefrom.

Figure 2 is a front elevational view of my supporting apparatus showing two swingssuspended therefrom.

Figure 3 is a sectional View taken on the line 33 of Figure 1.

Figure 4 is an enlarged sectional view taken on the line 4-4 of Figure 1.

As illustrated, my apparatus has a main supporting standard S consisting of an upright at each end, and at one or more intermediate points if needed. Each upright has two rods III that slant upwardly and inwardly towards each other, both being connected at the top by a fitting M, thus forming an upright of generally triangular shape. Said supporting standard also has a cross support bar l2 that is attached to said fittings l4 and extends laterally between said uprights, and which constitutes the main horizontal support of said standard S.

One spring member 20 having a curled portion at each end providing an eye 2|, and preferably formed of two spring leaves, is supported by said cross bar I 2. Retaining means keep said spring member in place and include two U-bolts 26 at opposite sides thereof, a flat connector 22 extending between and connected to said U-bolts and a bolt 24 that extends through and holds said cross bar l2, said spring member .20 and said connector 22 together, thus retaining said spring member 20 in predetermined mounted position on said cross support l2.

At each end of and supported by said spring member 20 is a swing supporting member shown in the form of a straight rod 28 which extends through a said eye 2|. At each side of the latter a sleeve 29 is mounted on said rod 28. Said swing support 28 has rotatable members shown as pulleys 30, rotatably mounted on opposite ends thereof and at one end they bear against said sleeves 29, thus spacing said pulleys 30 from said spring member 2!. Outside each said pulley 30 is a washer 3| and outside thereof a cotter pin 32 extends through said rod 28 to keep said pulley 30 thereon.

Two swing suspension members 35 shown in the form of chains, extend from each pair of said pulleys 30, and both connect, at their lower end, to a small roller 3'! that is rotatably mounted on a shaft 38. The latter is attached'to a connecting bracket 39 that is fixed to an end extension 4 I, extending upwardly, that forms one end of a swing 40, which, as shown, represents a horse, having a seat 42, and handles 44 for the child to hold onto.

Each said swing 40 is suspended at opposite ends by said suspension members, as shown in said Figure 1, hence the swing keeps a relatively true course and where several swings are mounted on one supporting standard they do not interfere with each other.

Said spring member 20 is sufiiciently resilient to yield somewhat with each swinging movement, hence the strain on my apparatus is greatly lessened and the swinging movement is smoother. This together with the rotatable members provides apparatus that is comfortable in action and durable.

What I claim is:

1. Supporting apparatus for a swing or the like comprising a main supporting standard embodying a cross support bar extending laterally, a spring support member extending laterally of and mounted on said cross support bar and two swing supporting members supported by said spring support member at opposite sides of said cross support bar, said swing supporting members being adapted to support suspension members for a swing.

spring support member extending laterally i and mounted on said cross support bar and two swing supporting members embodying two rods supported by opposite end portions of said sprin supporting memben'said swing supporting members being adapted to. support suspension mem bers for a swing.

3. Supporting apparatus for a swing or the like comprising a main supporting standard embodying a cross support bar extending laterally, a

spring support member extending laterally and I supported by said cross support bar; embodying eye portions at opposite ends thereof, and two swing supporting members each embodying a rod extending through said eye portions and adapted to support suspension members for a swing.

4. Supporting apparatus for a swing or the like comprising a main supporting standard embodying a cross support bar extending laterally, a sprin support member extending laterally of and supported by said cross support bar, retaining means retaining said sprin support member in predetermined position on said cross bar, and two swing supporting members supported .by said spring support member and adapted to support suspension members for a swing.

5, Supportin apparatus. for a swing or the like comprising a main supporting standard embodying a cross support bar extending laterally, a spring support member extending laterally of an moun e o s id. cross supp a w swing supporting members embodying two rods supported by opposite end portions of said'sprihg suppor ng member, said, ro s e ch e b y two. rotatable members spaced apart and rotatably mounted thereon, suspension members for a swing supported by said rotatable members and embodying two rotatable members, means rotatably supporting said latter rotatable members and adapted to be attached to a swing.

, 6,. A swing construction or the, like comprising a main supporting standard embodying a cross support bar extending laterally, a spring support member. extending laterally cross-wise of and mounted on said cross support bar, two swing supporting members embodying two rods supported by opposite end portions of said spring supporting member, said rods each embodying two. rotatable members spaced apart and rotatably mounted thereon, suspension members for a swing supported by said. rotatable members a embod i tw ro a abl memb sm rotatably supporting said latter rotatable mem-.

4 bers, and a swing embodying end extensions at opposite end portions thereof extending uprightly and attached to said means.

7. Supporting apparatus for a swing or the like comprising a main supporting standard embodying a cross support bar extending laterally, a spring support member embodying two leaves extending laterally cross-wise of and mounted on said cross support bar and having eye portions at opposite ends thereof, retaining means retaining said spring memberin predetermined position on said cross bar, two swing supporting members embodying two rods extending cross Wise of said spring support member through said eye portions, each said rod embodying two rotata-ble members at opposite end portions thereof, suspension members for a swing supported by and extending below said rotatable members and embodying two other rotatable members at the l wer end o ai s sp si n m m rs. m a s rotatably supporting said other two rotatable members and adapted o be attached to a swing. 8..A sw ne ons tio or i ompr si a mai pporting s an a m odyin a ross support bar extending laterally, a spring support member embodying two leaves extending laterally cross-wise of and mounted on said cross support bar and having eye portions at opposite ends thereof. retain g me s in n sa prin memb in. pre e rmine p sit on n said cross bar, two swing supporting members embodying two rods extending cross-wise of said p ng u p r me b r o h said ar no tions, each said rod embodying two rotatable members at opposite end portions thereof, suspension members for a swing supported by extending below said rotatable members and embodying two other rotatable members at the lower end of said suspension members, means rotatably supportin said other two rotatable members. d a swing embodying upright 611d. extensions at opposite end portions thereof attached at their upper ends to said means.
