8 Claims.
This invention relates to improvements in coaster wagons designed for use by children for amusement and exercise and particularly to steering coaster wagons of a form generally corn- 5 parable to steering sleds, and thus capable of use by a person either when sitting upright or lying prone thereon.
More particularly, the invention is concerned with providing an improved steering mechanism and front end assembly for a coaster wagon of this character which is in some respects similar to the steering mechanism of certain types of steering sleds in its ultimate effect and mode of operation, the front wheels of the coaster being turned to right or left when steering by means of a transverse horizontally extending steering bar disposed adjacent the front end of the vehicle and adapted to be actuated either by the, hands or feet of the occupant.
A principal object of my invention is to provide a coaster wagon of this character embodying steering mechanism in which a pivotal connection between the front portion of the coaster and the front wheels enables the coaster to be steered with a minimum of effort while providing relatively great strength and durability to resist breakage from impact with obstructions and torsional stresses resulting from irregularities in the surfaces over which it may be required to pass.
A further object of the invention is to provide a coaster having a minimum of parts and capable of being marketed in a knocked down condition, thus permitting ease of shipment and handling prior to its assembly by the ultimate purchaser for actual use.
A still further object of the invention is to provide a coaster front end assembly in which road shocks and'the like are absorbed by distri uted through the principal strength members of the coaster rather than transmitted to the body of the user whereby the riding qualities of the vehicle are improved and its probable life in actual use substantially increased.
Another object of the invention is to provide a coaster embodying a deck supporting frame rigidly connected with the rear axle and pivotally connected at a point adjacent the front end of the coaster with the front axle, nus providing in effect a three-point or tripod supperu for the 7 frame and deck, whereby undue torsional stresses therein as a result of irregularities in the road are prevented. v
A still further object is the provision of means in a coaster of this character whereby the center (Cl. EMF-87.5)
deck panel is relieved of and protected from road shocks which, in the absence of said means, would tend to crack the panel and/or loosen it from its fastenings. I
Other objects, purposes and advantages of the invention will hereinafter more fully appear or will be understood from the following description of a coaster wagon constructed in accor ance therewith during which reference will be had to the accompanying drawing.
In said drawing, Fig. 1 is a side elevation of said coaster wagon, a portion of one of the side rails being broken away; Fig. 2 is an enlarged fragmentary top plan View of the front part of the coaster shown in Fig. 1; Fig. 3 is a similarly enlarged fragmentary front elevation thereof Fig. 4 is a fragmentary verticalsection on the line 44: in Fig. 3, and Fig. 5 is a still further enlarged perspective view of certain of the parts utilized for making the steering connection between the steering bar and the front axle. In the several figures like characters are used to designate the same parts. p
- Referring now. more particularly to the drawing, as shown in Fig. l the coaster comprises generally a frame having side rails and cross mem bers carrying a top deck 1 supported from a rear axle having a pair of wheels 2 arranged for rota tion on anti-friction bearings and a front axle 3 having a pair of similar wheels 4 provided with anti-friction bearings, which is controlled from the steering bar 5 in a manner, now to be described. v
As most clearly shown in Fig. 3, the connection with the front aXle'3 comprises a yoke 6 desirably made of a single strip of relatively heavy metal such as steel or the like bent into the form shown and having holes adjacent its downwardly turned lower ends for passage of the axle 3, a brace 7 extending aboveand parallel to the axle being riveted or otherwise secured to the yoke to maintain its lower ends in spaced relation adjacent the wheels 4 into which the outer ends of the axle extend. Adjacent their front ends the side rails 3 of the frame are interconnected by a fiat metal spacer 9, the ends of which are preferably riveted to the side rails, and interposed between the central portion of the spacer and the yoke 6 is a chair 10 more particularly shown in detail in Fig. 5 having its divergent arms 11 riveted to the yoke 6 at spaced points while itsupwardly offset central portion 12 provides a bearing for the spacer 9 adjacent its center; a similar chair 10 is disposed in inverted position above the spacer 9 in substantial registry with the chair 10, the divergent arms 1.1
of this chair being riveted to the steering bar 5 at spaced points to thereby secure the latter to thechair, both chairs being perforated substantially centrally to provide holes 13, 13 which are thus in vertical alignment with each other when the parts are assembled. A metal tongue 20, secured to the central panel 21 of the coaster deck 1, extends forwardly therefrom into the space between the offset central portion 12 of the chair 10 and the steering bar 5.
The steering bar 5, tongue 20, spacer 9 and yoke 6, are also respectively provided with holes in alignment with those in the chairs and thus adapted for the passage of a king pin 22 which is preferably squared beneath its head for reception in the squared central hole of a washer 23 having downwardly projecting points 24 which may be driven into the wood of the steering bar 5, thus preventing the pin 22 from turning with respect thereto after assembly. A castellated nut 25 is threaded onto the lower end of the king pin which passes through the bar, tongue, spacer, chairs and yoke to secure the several parts in relatively loosely assembled relation, a cotter pin 26 preventing the nut from backing off.
As will be apparent from Fig. 5, the chairs 10, 10 are preferably sheet metal stampings and are substantially identical except that when assembled, they occupy reverse or inverted positions. Each of the chairs, moreover, has a rearwardly extending tongue 28 and a lug 29 projecting laterally outward therefrom provided with a hole 30 for a purpose which will hereafter appear. The tongue of the chair 10, however, is provided with a downwardly extending pin 32 preferably riveted or otherwise secured thereto and adapted for reception in a hole 33in the tongue of the chair 10 so that when assembled, as best shown in Figs.
.2 and 4, the pin 32 enters this hole and prevents relative rotation between the chairs about the king pin 22. Thus, the cross bar 5, secured to the upper chair 10, is interconnected with the axle 3- through the lower chair l0 and yoke 6, so that movement of the steering bar about the king pin 22 correspondingly moves the axle to steer the coaster. As the spacer 9 is loosely disposed between the chairs, it is capable of slight rocking movement on the lower chair 10, thus relieving excessive and torsional stress on the frame and associated parts.
A tension spring 35 is extended between the lug 29 of the chair l0 and the adjacent side rail 8 and a similar spring 35 between the lug 29' and adjacent side rail, each spring thus tending to urge the outwardly projecting tongues of the chairs toward the side rail to which it is secured. As the springs are preferably of substantially equal strength, when they are in equilibrium they yieldingly maintain the tongues centrally of the coaster and the front wheels in turn in parallelism with the rear wheels, while when the front wheels are turned either by pressure on the steering bar 5 sufficient to extend one or the other of the springs to steer the coaster to right or left or by one of the wheels encountering an obstruction, the springs return the front wheels to their former or straight line position immediately the pressure on the bar is released or the obstacle passed over.
In order to provide a strengthening support 'for the front end assembly and relieve undue stresses on the king pin 22, I provide an angular strut 40 extending rearwardly upwardly from the brace '7 parallel to the longitudinal center line of the coaster and pivotally secure it to the brace by a rivet 41 just above the mid-point of the front axle, a washer 4'2 being interposed between the strut and brace to minimize friction and permit free relative pivotal movement of the axle during the steering of the coaster. The rear end of the strut 40 is secured to the tongue 20 and to the center deck panel 21 through the medium of a bolt 43 and nut 44, thus firmly bracing the front axle assembly.
The tongue 20, bearing loosely on the chair 10 at its forward end and extending rearwardly beneath the center deck panel 21, is secured to the latter at spaced points by rivets 45, 46. This tongue is desirably made of relatively heavy strip steel and at its rear end is bent to form an ofZse-t downwardly and rearwardly projecting finger 47 which engages the lower surface of the forward wooden cross bench 48 of the coaster. As this cross bench is supported from the side rails 8 and provides a support for the coaster deck panels, the arrangement of the parts just described is such that a shock received by the front wheels upon encountering an obstruction is transmitted through the strut 40 to the tongue 20 which rises slightly at its forward end to bring it into engagementwith the steering bar 5; the rear end of the tongue is prevented from rising, however, throughthe engagement of the finger 47 with the cross bench and the tongue thus'acts in effect as a spring to absorb a large portion of the shock and to distribute the remainder to the steering bar 5 or to thecross bench and thence to the center panel 21 of the deck. The latter of course also absorbs a portion of the shock but not enough to split or otherwise injure it, while as it is prevented from relative movement with respect to the cross bench by the finger 47, the nails 49 or other fastenings which secure it thereto cannot become loosened or dislodged even when the coaster is subjected to severe usage.
Thus, by my invention, I provide an extrerne ly durable coaster wagon in which wear or brealo age and consequent necessity for repair or replacement of its parts are reduced to a minimum, those parts which are normally subjected to greatest direct strains being so arranged with respect to other parts serving as reinforcing members that the principal strains ordinarily imposed thereon are relieved and widely distributed through the other parts of the coaster, while the steering assembly is subjected to substantially no wear or strain of the character generally found in vehicles of the class to which my invention is directed, i. e., that resulting from a torsional stress imposed upon some part in order to turn the wheels in response to a movement of the steering bar or equivalent mechanisrn. The stress members of my improved steering mechanism are desirably made entirely of steel, and are thus capable of withstanding severe usage; as the provision of a wooden steering bar is desirable for attractiveness of appearance and other reasons, it is permitted by utilization of the metal chairs 10, 10', the upper one of which, secured to the steering bar at widely spaced points, maybe readily turned thereby to steer the coaster with a Moreover, the rearwardly extending tongues of the chairs, to which the springs 35 are secured, provide sufficient leverage for the latter to enable them to resist relatively strongly any deflection of the front wheels upon encountering an 0bstruction, and to return the wheels very quickly to their normal position immediately upon their minimum of effort.-
parall release, thus enhancing the safety and the pleasure afforded to the user.
Furthermore, since the tongue 29 is received between the upwardly offset arms 11' of the chair 10', it serves as a stop to limit the amount which the steering bar and front wheels can be turner in either direction from straight ah ad position; excessive stretching of the springs 35 is thus prevented, and danger to the occupant of the coaster through turning too sharp a corner is averted.
The safety of the occupant is additionally protected by the provision of a bum er or guard 59, which may comprise a single strip of steel bent to the form indicated in Fig. 2 and having its ends secured to the forward'ends of the side rails 8 in such manner that the bumper projects forwardly from the front of the coaster to encounter any obstacle which may be interposed in its path and transmit the shock of impact to the side rails.
As hitherto mentioned, the coaster wagon herein disclosed readily lends itself to shipment by the manufacturer in a knockdown condition. To this end the rear axle may be supported by a yoke 52 pivoted to the side rails and adapted to held in vertical position by struts 53, he forward ends of which are reniovably bolted to the center cross bench 5a, the rear wheels being designed for ready removal from or attachment to the axle; when the struts are taken off and the wheels removed, the axle and yoke can be folded up adjacent the under side of the deck. L kewise when the springs 35 are unhooked and the king pin 22 removed, the steering bar 5, chairs it), ill, yoke 6 and front axle can be detached from the e and deck after the strut .0 unbo-lted from latter so that when the fr n wheels are removed from the axle, these various parts can be folded up and packed flat with the deck and frame, thus permitting all of the parts of the coaster wagon to be enclosed in a flat package or carton of corn venient dimensions for handling and shipment. The method of assembling the parts into operative position by the dealer or ultimate purchaser will be readily apparent.
While I have herein described one embodiment of my invention with considerable particularity, it will be understood that I do not intend thereby to limit or confine myself thereto, as changes and modifications in the form and of the several parts will readily occur to those skilled in the art and may be made if desired without departing her the spirit and scope of the irrtion as defined in the appended claims.
