1 Claim.

1; Another object of this invention is to produce ;-;an improved suspension mounting for a swing on a supporting frame in a manner to increase I,

the riding comfort and appearance and at the same time militate against the dangers of upsetting as well as pinching portions of the person's wearing apparel between cooperating parts.

,. Ot her objects and advantages will become "apparent from the following description and claims, and for purposes of illustration but not of limitation, embodiments of the invention are shown in the accompanying drawings, in which 1 Figure 1 is a perspective view of the improved swing embodying the features of this invention; Figure 2 is an enlarged fragmentary side elevational view of the swing showing in detail the arrangement and construction of the suspension straps;

Figure 3 is a perspective fragmentary view of another form of the invention; and

Figure 4 is a detailed front elevational view of a, portion of the swing illustrated in Figure 3.

Referring now to the drawings, an upright supporting standard is provided and consists of a pair of sup-porting frames In each formed of similar interconnected rigid members, for example of three channel members H, 12 and 13 joined at their respective ends as by welding, riveting or nut and bolt means, in a manner to form a triangular section having one side wall as the base to prevent tippin transverse to the planes of frames I when standing on a substantially flat floor or on the ground. A cross arm or crown bar 14 interconnecting the vertices of the spaced apart triangular members, is reinforced by angularly disposed braces l join ing inner portions of the cross arm i l with lower portions of the triangular sections, thereby also to enhance the rigidity of the supporting frame.

Secured as by welding to the crown bar l4 in the region near the respective ends are a pair of depending hooks that might take the form of a bail It. To each bail there is anchored one end of a link in the form of a coil spring ll as by 2 means of a hook I8 formed integral with each spring end, it being understood that there are two such springs, the other end of each coil spring terminating in the form of an integral depending eyelet or hook I!) for engagement with the swing supporting members to be described.

The seat member 20 comprises a rectangular frame 2! having an end plate 22 of metal or the like secured to each lateral end by the ordinary metal joining means such as welding, riveting, screws or the like. The upper portion of each end plate is formed with an outwardly disposed arm rest 23 which may be curvilinear or substantially flat in cross section and has a downwardly turned skirt 2d integral with the outer end. A back rest 25 pivotally mounted by well-known means to the lower rearward portion of the frame 2| ha pins 26 extending laterally from an intermediate portion of the. back rest'selectively to seat in notches 21 of a rack bar 28 pivotally secured at one end to an upper rearward portion of each end plate 22, thereby adjustably to dispose the back rest in the desired angular relationship with respect to the frame. Cushions 29 on the seat and back rest enhance the comfort as well as the appearance of the swing.

For purposes of suspending the seat member to the supporting frame in a manner enabling to and fro swinging movement, there are provided straps which might consist of chains, cable or belting but preferably are formed and herein described as rigid metal members, a pair 30 and 3| of which engage each end of the seat member. The lower end portions 32' of each pair of straps are secured respectively to the lower corner regions of each end plate and from there are outwardly inclined in substantial parallel relation to abut the outer surface of the depending skirt 24 to which they are secured by bolt, screw, rivet or other metal joining means 33, thereby rigidly to mount each strap member at two spaced apart points to the seat member in a manner enabling full use of the arm rest.

The portions of each arm 30 and 3| extending upwardly beyond the arm rest 24 are bowed at 32, or inclined toward each other bringing their ends in overlapping relation so that apertures 33 in the ends of each are in registry enabling a pin 36, bolt and nut means or the like pivotally to mount each pair of strap arms to respective eyelets depending from the spaced coil springs as described. The arms may also be inwardly inclined as shown at 35 where desired.

It is apparent that the arrangement of members not only enables full use of the arm rest to increase the comfort of the occupants, but the rigid spaced metal supporting straps engaging the seat member at multiple spaced apart points militate against upsetting of the seat member not infrequently resulting from the use of collapsible mounting means when a shifting of weights naturally urges the seat member to be tilted backwardly or forwardly.

Another form of the invention illustrated in Figures 3 and 4, comprises substantially the same parts described, the differences mainly residing in the means mounting the seat member 20 with the suspended coil springs H. For this purpose there are provided a pair of rigidstraps 35 and 36 of metal or the like mounted in vertical parallel relation to the outer wall of each end plate 22, preferably in the region-adjacent the forward and rearward edges respectively.

end plate by means of two or more screws 31,

bolts,,rivets or: the like, and has one end portion of a pin 42 or bolt, the assembly may be pivotally connected to an eyelet 33 depending from each coil spring aspreviouslydescribed. For purposes of greater comfort, freedomcf arm movement and appearance, each hanger strap may be curvilinear to appear in; the assembled position as a tong-like suspension which is immovable in view of the fact that each of the three corners is anchored.

Inthis manner, there is, provided a more simplified rigid mounting for the seat member enabling uninhibited to and fro swinging movement without the fearof upsetting. In both described modifications, there are no movable parts within the ordinary reach of occupants that might other- Eaoh' strap is stationarily secured to the respectivewise be dangerous enabling the swing to be used by children who, during use, might grasp the hanger straps or the like. Through the use of hook members as well as bolt and; nut joining means, the installation or dlsassembly of the.

swing may be readily effected without the use of skilled labor or special tools.

It is apparent from the description that I have produced a, swing incorporating new and novel features enabling safer and more comfortable use and which consists of such simple contoured parts as to enhance the appearance and sturdinew as well as the manufacture and assembly 01 the swing.

It is to be understood that numerous changes may be made in the details of construction, and arrangement without departing from the spirit of the invention especially as defined in the appended claim.

. What 'I claim is:

Ina. swing suspended from the crown bar of an upright supporting standard, the swing comprising a seat having upright end members, an arm rest extending laterally outward from the upper end of each endmember, and means for suspending each end of the swing from the. supporting standard including a pair of rigid strap metal arms joined at their upper ends, link means connecting the joined ends of the arms to the supporting standard crown bar, said arms ex tending divergingly from their joined ends and bowing outwardly and downwardly to the outer side of the adjacent arm rest, fastener means securing each arm to the arm rest, lower end portions of said arms inclining downwardly and inwardly'from' the arm rest to the lower portion of the adjacent end member, and'fastener mea'n's securing the lowerends of said arms to the-end member.
