4l Claims. (Cl. 1554-58) This invention relates to improvements in swing s'eats for swings such as are used on playgrounds. y

jThe object of the invention is to provide improved means for cushioning the edges of a core of a swing seat to prevent injury to a child in the event it is struck by the seat, the core being shown in the present case as a rigid one, although rigidity ofthe core is 'not essential.

In the accompanying drawing:

Fig. 1 is a plan view of one side of a swing seat embodying the invention, a part thereof being broken away and shown in section, the secftion being on the line I-I of Fig. 2. 1,5 Fig. 2 is a view partly in side elevation and partly in longitudinal section, the section being on the line 2--2 of Fig. 1.

Fig3 is a transverse section on the line 3 3 of Fig. 2.

Fig. 4 is a transverse section on theline 4-4 of Fig. 2.

Fig. 5 is a side elevation of one of the metallic reinforcing strips for the side cushions.

Fig. 6 lis a modification in the form of the 25 metallic reinforce for the side cushions.

constructed of Wood, although any other suitable y material may be used. In order to protect the 30 side edges of this core there is employed for each edge a cushioning member 2 preferably formed of rubber. The cushioning member in the present case is formed hollow. The outer portion of this cushioning member 2 is preferably of a 35 rounded form but the inner side thereof indicated at 2 is preferably formed in the nature of a straight wall from which project flanges 2" so as to form a channel which fits the edge of the core I of the seat.

The intermediate portion of this cushioning member is in the present case secured to the seat by one or more screws 3, two scre'ws being shown in the present instance. The heads of the screws hold in position against the inner surface of the 45 wall 2' a stiiening strip 4 which has apertures I' to receive the screws, the strip in the present case being metallic, although any other suitable material may be used. The ends of this strip I terminate short of the ends of the cushioning 50 member as shown in dotted lines in Fig. 1. The cushioning members 2 have apertures I2 aligned with the apertures 4' to permit the insertion of a suitable tool to engage the heads of the screws to screw them into the core.

Each cushioning member is also further held or curved hollow portion of the-cushion is availin position on the edge of the core by bolts 5 which also serve to retain the stiffening strips 4,

the seat. Each of these bolts extends through an aperture 4" in each of the stiffening strips and v through a bore 6 in a reduced portion I' of the core, the head 5 of the bolt and a nut 5 on the opposite end of the bolt serving to clamp the strips to position. Sleeves i surround each end of each bolt and serve as bearings for the eyes of a cievis' I I; the apertures in the side cushioning members to which the bolts extend being enlarged suil'iciently to receive these sleeves.

The ends of the core I are protected by cushioning members 8 also preferably formed of rubber similar to the side cushions. 'I'he outer side of each of these end cushions is rounded and the inner wall B' is preferablyI formed straight and has projecting from the sides thereof side flanges 9 connected by webs 9 to form a socket which is forced with a tight fit over the reduced portion I of the core. The flanges 9 are formed with apertures to receive the sleeves 'l on the bolt 5 as shown in Fig. 3 and the sleeves and bolt therefor serve to hold the end cushioning member in position.

In Fig. 6 a modification is shown in the form of the reinforce for the side cushioning members.

Instead of a continuous strip 4 as described, short strips I0 are employed, one of these short strips being provided in each cushion for each of the bolts 5 and the screws 3, the short strip being provided with an aperture I0 through which the bolts and screws pass.

One of the advantages of this arrangement is that by having the reinforce clamped against the inner wall of each cushion, the entire outer able to absorb shocks as distinguished from a hollow resilient cushioning member in which the reinforcing member extends through the center thereof.

Another advantage in the arrangement is'that all of the edges of thesolid core are protected by cushioning members and that there are'no unyieiding parts of the seat, such as vthe core, or the reinforcing members which are unprotected bw the cushion, as it will be seen that the reinforcing members terminate short of the ends of the forward cushions so that there is no opportunity for such .metal reinforcing members to strilxe a child in the event ofcontact of the seat witha. child and the same thing is true of the solid core which is not only protected lby the cushions at the sides but at the ends.

It will be seen that the clevis which serves as a means for connecting the seat with the suspension cables or ropes may be swung about the bearing sleeves so that if desired the seat may be readily reversed, both sides of the seat being alike.

Having thus described our invention, we claim:

1. In a swing seat, a core having reduced ends, protecting cushions embracing said reduced ends, protecting cushions secured to the side edges of said core, a bolt at each end of said core extending through both side cushions and an end cushion and also through the core. said reduced ends of the core providing spaces between the side cushions and the end cushions, bearing sleeves on said bolts extending throughsaid cushions and through said spaces and shouldered against said core. and a clevis at each end having eyes pivotally mounted on said sleeves to permit the clevis to be swung from one face of the seat tothe other and the seat reversed.

2. In a swing seat, a core having reduced ends. protecting cushions embracing said reduced ends, protecting cushions secured to the side edges of said core, a bolt at each end of said core extending through both side. cushions and an end cushion andalso through the core, said reduced ends of the core providing spaces between the side cushions and the end cushions, means to maintain the ends of the side cushions in spaced relation with the reduced Vends of said core, and a clevis at each end of said seat cooperating with said bolts to support the seat.

' 3. In a swing seat, a core, a hollow protecting cushion for each side edge of said core, the inner wall of each cushion having both sides thereof formed on a straight line.v a metallic reinforcing. strip for each side cushion positioned against the straight inner surface of the inner wall thereof. and mea'ns engaging each reinforcing strip and extending through the inner wall of the corresponding cushion and into said core to clamp each reinforcing strip to the inner wall of the corresponding cushion and said inner wall to the core.

4. In a swing seat, a core, a hollow protecting cushion for each side edge of said core, the inner. wall of each cushion having both sides thereof formed on a straight line, a metallic reinforcing strip for each side cushion positioned against the straight inner surface of the inner wall thereof, means engaging each reinforcing strip and extending through the inner wall-of the corresponding cushion and 'into said core to clamp each reinforcing strip to the inner wall of the corresponding cushion and said inner wall to the core, a protecting cushion secured to each end of said core, and means to attach said end cushions to said core.
