3 Claims.

My invention relates to chair swings of the type adapted for use on porches and lawns.

It is the object of my invention to provide a swing of this type so constructed as to be knocked down or collapsed into a small compass for shipping or storage purposes and which when set up shall possess greater strength andrigidity with a greater freedom of movement than swings of conventional construction. Other and more specific objects of my invention will be apparent from the following specification and claims.

In th accompanying drawings which illustrate one embodiment of my invention:

Fig. 1 is a side elevation; Fig. 2 is an end elevation; Fig. 3 is a detail section on line 3--3 of Fig. 2; Fig. 4 is a detail section on line 4.-4 of Fig. 1; Fig. 5 is a detail section on line 55 of Fig. 2; Fig. 6 is a plan View of the floor assembly; Fig. '7 is a detail section on line 77 of Fig. 6; Fig. 8 is a detail section on line 88 of Fig. 6; Fig. 9 is a side elevation showing a modified form;

Fig. 1D is an end elevation of the structure shown in Fig. 9;

Fig. 11 is a plan view of the floor assembly of the structure shown in Figs. 9 and 10;

Fig. 12 is a detail section on line 12-12 of Fig. 11;

Fig. 13 is a detail section on line 13-13 of Fig. 11;

Figs. 1 1 and 15 are detail views on a smaller scale showing one manner of connecting the frame to other uses; and

Figs. 16 and 17 are fragmentary details of an alternative form of hanger.

As shown in the drawings, the swing comprises a stationary frame formed by four inciined members 1 connected to form respective end pairs by cap members 2 and 3. The cap members are secured to the inclined members by means of angle irons 5 and bolts 6. The connection of the cap members to the inclined members is braced and made rigid by suspension irons S which may be secured in place by separate bolts but preferably are held by the bolts .6 remote from the intersection of the inclined members and cap members. Crossed side members 9 connect the side pairs of inclined members 1. The upper'ends of the crossed members are held by the bolts 6 which hold the adjacent suspension irons 8 to the inclined members while their lower ends are secured to the adjacent inclined member by bolts 10. The crossed side members are held together at their intersection by bolts 12. Foot members 13 and 14 respectively connect the end pairs of inclined members 1 by means of angle irons 16 and bolts 1'7, as shown in detail in Fig. 5.

The swing proper is supported by suspension 'gitudinal member 41.

members 19. The suspension members are freely hung on the suspension irons 8 by means or" pear shaped apertures formed in one end of the members. The upper portion 20 of these apertures snugly fits the irons 8, as best'shown in Fig. 3, while the lower portion 21 is made sufficiently large to permit passage of the looped end of the suspension iron during assembly. The ends of the suspension members are reinforced by bolts 22.

The side pairs of the suspension members are respectively connected at their lower ends by spanner members 23 and 24. This connection is made by means of bolts 25 provided with sleeves 26 (see Fig. 4), permitting easy pivotal movement between the suspension and spanner members. Each end pair of suspension members 19 supports a chair formed by chair back members 27 pivoted at their lower end to the adjacent suspension member by the sleeved bolts 25 previously mentioned. Slatted chair backs, formed of slats 28 nailed or otherwise permanently secured to side pieces 29 are secured between the members 27, as best shown in Fig. 2, by bolts 30, the slats 28 extending over the members 27 to prevent turning of the backs about bolts 30 and to give added rigidity to the assembly. Seat members 31 connect each chair back member 27 to its adjacent suspension member, members 31 being secured to members 27 by bolts 32 and to suspension members 19 by bolts 34. Bolts. 34 also pass through side members 35 to which are nailed or otherwise permanently secured slats 36, forming unitary slatted seat members.

The floor of the swing, as best shown in Fig. 6, is made in two sections, spanner 23 forming a permanent part of one section and spanner 24 a permanent part of the other. Slats 38 are nailed or otherwise permanently secured to spanner 23 and a longitudinal member39. Slats 40 are similarly secured to spanner 24 and a lon- As best shown in Figs. 6 and 7, longitudinal members 39 and 41 are provided at their ends with rectangular hooks 43 engaging over transverse members 44 and 45 which are provided on their ends with similar hooks 46 engaging spanner members 23 and 24. As shown in Fig. 8, hooks 46 are slightly wider than the spanners. This is desirable to permit the hooks to rock slightly about the spanner securing a greater ease in assembly, particularly where the parts are too stiff to permit them to be sprung into place.

In the modified structure of Figs. 9 to 15, inclusive, are disclosed alternative and modified forms of construction and assembly which have certain advantages from the viewpoint of construction cost and interchangeability of parts, thus increasing the field of use. As in the form previously described, no dowels or tenons are necand swing members being assembled in face to face or surface contact.

Referring now particularly to Figs. 9 and 10, 51 designates four inclined members connected at their upper ends, to form respective end pairs, by cap members 52 and 53. As will be clear from a comparison of Figs. 1 and 9, the members 51 of each pair face the opposite pair flatwise. This permits the use of ordinary bolts 54 for fastening the cap members 52 and 53 to members 51, as well as for securing the foot members 55 and 56 to members 51. The frame proper is completed by cross braces 57 and 58 secured to opposite end members 51 by means of suitably shaped channeled angle irons 59 and bolts 60.

The swing is supported by suspension members 61 provided at their upper ends with channel irons 62, secured by bolts 63. Members 61 are hung from brackets 65 bolted at 63' to the cap members and are pivoted in slots 64, formed in the depending brackets 65, by bolts 66.

The side pairs of the suspension members 61 are respectively connected at their lower ends by spanner members 67 and 68. This connection is made by means of sleeved bolts '70 permitting easy pivotal movement between the suspension and spanner members. Each end pair of suspension members 61 supports a chair formed by back members '11 and seat members '72 bolted together as in the construction first described, and similarly provided with slatted back and seat units 73 and '74 respectively. In the modified form now being described, the floor of the swing (see Figs. 9 and 11) is formed of two transverse sections '76 which are exactly similar and formed from pieces having the same dimensions as back and seat units '73 and '74 and are interchangeable with the seat members '74. As best shown in Figs. 11, 12 and 13, the slats of the floor are reinforced by a central piece '77 provided at each end with a cross piece '78. Pieces '78 are provided with hooks '79 engaging over spanner members 6'7 and 68. The end pieces 78 are preferably pivoted as at 80 to the central piece '77 so that the end pieces may be pivoted into alignment with the central piece for shipping.

As indicated in Figs. 14 and 15, suspension members 61 may be easily replaced by longitudinal beams 82 provided with vertical irons 83 which are adapted to be held in brackets 65 by the bolts 66 in the same manner as were the irons 62 of the suspension members 61. Beams 82 may be provided with a trapeze 85 and flying rings 86 or other apparatus to convert the swing into a playground gymnasium.

In Fig. 16 is shown a modified form of bracket or hanger 90 which may replace bracket 65 above described. Hanger 90 is simpler in form and is pivoted to iron 62 of the suspension member 61 by a rivet or short bolt 91.

In Fig. 1'7 is shown an alternative manner of connecting suspension members 19 to irons 8, which comprises a slotted iron 15 bolted to the end of the suspension members 19.

It will be seen from the above description that all the frame and swing members are assembled in face-to-face contact, and that no dowels or tenons are used in the construction of the swing, yet a more rigid and sturdy structure is secured than by the conventional practice. The swing can be completely knocked down for shipment or storage to form a package having a maxi mum length equal to the length of inclined members 1 or 51 and a maximum width equal to that of the slatted seat units. The complete absence of dowels or tenons also greatly simplifies the manufacture and finishing of the parts.
