CHILDREN'S BOAT SWING Filed June 29, 1954 f :Y I INVENTOR.' Z flilglglgn DM Vm United States Patent() CHILDRENS BOAT SWING Paul V. Jensen, Minneapolis, Minn.

Application June 29, 1954, Serial No. 440,205

2 Claims. (Cl. 155-58) My invention relates to swings for children and has for its primary object the provision of a device which may be readily assembled and disassembled.

A 'further object of my invention is the provision of a novel framework and cooperating swing structure which occupies suiciently small space when assembled to be capable of use indoors.

A still further object :of my 'invention is the provision of a device of the class above described which is Irelatively inexpensive to produce, `which has a minimum of parts, which is extremely rugged in construction and durable in use.

The above and still further objects of -my invention will become apparent from the following detailed specification, appended claims and attached drawings.

Refer-ring to the drawings wherein like characters indicate like parts throughout the several views:

Fig. l is a view in perspective of my swing;

Fig. 2 is a View in side elevation; and

Fig. 3 is a view in end elevation, some parts being broken away and sh'own in section.

lReferring with greater particularity to the drawings, the numeral i1 indicates in its entirety .a frame comprising a pair of laterally spaced generally U-fshaped side frame members t2 each comprising elongated groundengaging elements 3 and upstanding front and rear leg elements 4 and 5 respectively. 4Front and rear leg elements 4 and 5 converge upwardly Iand terminate in spaced relation. yFratrie I1 also includes front land lrear yframe members `6 and 7 which Iare identical in all respects and which 'are generally 'U-shaped inverted `whereby their tubular depending `end portions "8 may slidably telescopically receive the upwardly projected ends of the legs 4 and 5. Side `frame members 2 may be formed from metallic rod :stock or metallic pipe stock whereas the front and rear frame members 6 and 7 may be formed from tubular metallic p'ipe sto'ck.

-It will be noted that the -depending end portions 8 of members 6 and 7 diverge `downwardly and ythus likewise securely retain the `front legs l4 and the rea-r legs 5 of the side lframe members in a downwardly diverging position so as to space the ground-engaging -portions 3 sufficiently far `apart to impart stability and a low center of gravity to the frame 1.

A seat in the nature yof a boat-shaped structure 9 has forwardly converging :side walls 10, a 'bot-tom 11 upwardly spaced from the ground and a relatively wide stern 12. A seat element 13 is connected between the side walls immediately ladjacent the stern I12. lIt will be noted that the rear frame member 7 has a 4transverse Width greater than the width of the seat 9 as defined by the stern 12. Means in the form of rea-r ropes of cables 14 are secured to opposite sides of the seat 9 as indicated at 15 and have their upper ends looped through laterally spaced eyes 16 the threaded upper ends of which project through the frame members 7 and are secured thereto by means of nuts or the like '17. At its forward end a cable or rope 18 is secured to the front 2,791,267 lfatented. May 7, 1957 ice end of the seat 9, as at 19, and its upper end to an eye 20 which is secured to the intermediate portion of the front frame member as at 21.

As shown in Figs. :1 and 2 the feet 3 `of the side frame members 2 yare spaced -apart substantially to give the structure -a relatively low center of gravity and as shown in Fig. 2 the converging legs 4 and 5 not only reduce the area of the frame but make it possible `for the cables 14 and 18 to hang vertically when the seat is in a nonswinging position.

IThe front and rear frame members 6 and 7 respectively Iare connected `by a pair of longitudinally extending rigid struts 22 that are provided at their `opposite ends with coupling members 23 which embrace 4the members 6 and 7. The struts 22 transfer any swaying movement imparted to one of the pairs of legs 4 and 5 `by swinging movement of the boat-shaped structure 9 to the other pair of legs, so tha-t neither pair of said legs are placed under undue strain -at any time during use. During forward swinging movement of the structure 9, the rear legs 5 tend to sway forwardly and downwardly, and :this swaying movement is transferred through the `struts 22 to the front legs 4 whereby to cause Isaid front legs to sway forwardly and upwardly, thereby imparting a rocking movement to the structure 9 in addition -to the forward and rearward swinging movement thereof. Obviously, during rearward swinging movement of the structure 9, the front legs 4ilwill tend to swing `rearwardly and downwardly while `the rear legs '5 `will tend yto move rearwardly and upwardly.

#The particular mounting of the structure 9 prevents 'tipping thereof to either side, and the 'close proximity thereof to the ground enables the Isame to be used by very young children without danger of injury to the users.

=My invention has been thoroughly tes-ted and -found to be completely satisfactory for the accomplishment of the above objects; land while I have shown a preferred form thereof, it should be understood that same is capable of modification without departure from the scope of the 4appended claims.

What 'l claim is:

1. In a childs swing, a supporting structure involving a pair of laterally Ispaced generally U-sh-aped tubular side frame members each comprising elongated groundengaging elements and upstanding front and rear leg elements, inverted `U-shaped front and rear end frame members telescopicaily receiving the upper end portions of the front and Vre-ar en-d elements respectively to Ianchor -an-d brace the side frame members in laterally spaced relation, a seat, means for suspending the seat for swinging movements between the side frame members and in a direction generally parallel thereto, said means comprising hanger members connected to the -front and rear ends of said seat and to the front and rear end `frame members respectively, a pair of laterally-spaced, longitudinally-extended rigid struts, and coupling members on opposite ends of said struts loosely embracing the opp'osite end portions of said front and rear frame mem-bers, whereby swaying movements imparted to one pair of said leg elements in a direction generally longitudinally of the structure is transferred to the other pair of said leg elements.

2. `In a childs swing, a supporting structure involving a pair Vof laterally spaced generally U-shaped tubular side frame members each compri-sing elongated groundengaging elements and upstanding front and rear leg elements, inverted U-shaped front and rear end frame members telescopically engaging the upper end portions of the 'front and rear end elements respectively to anchor `and brace lthe side frame members in laterally spaced relation, a seat, means for suspending the seat for swinging movements between the side frame members and in a direc-tion generally parallel thereto, said means comprising hanger members connected to the front yand rear ends of said seat and to the front and rearfendfranie members respectively, longitudinally extended rigid strut means, and coupling members on oppositeends of said 823,386 strut means embracing the opposite `end por-tions of vsaid 1,026,179 front and rear `frame members, whereby swaying move- 2,423,950

ments imparted to one pair of said leg elements in a 10 2,569,596

Ydirection generally longitudinally of the structure is transferred to vthe other pair of said leg elements.
