CHILDS CAR.

Specification of Letters Patent.

Patented May 6, 1919.

Application filed December 9, 1918,. Serial No. 265,937.

To allwhbm it may concern: I

Be it known that I, MAGNUS H. WIQKMAN, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented new and useful Improvements in Childrens Cars, of which the following is a specification. This invention relates toim rovements in cars, wherein propulsion is e 'ected by the users feet acting on the ground or running surface to impart advancing thrusts to the car, the same being essentially'for children.

Children not only out-grow these cars but dealers are now required to stock numerous sizes of cars to meet the demands of the trade for children" of diiferent sizes, and

when it is considered how manydifferent types of cars are on the market, the dealer is at a decided disadvantage as regardsthe amount of goods of this type which it is now necessary to carry.

Therefore, it is one of the objects of this invention to provide a car which is readily adjustable from one extreme to the other to fit any size child-that would be attracted to the use ofsuch'a car.

A featureof this invention is to provide a frame of scissorsfformation on which a suit able seat is superimposed, hearing wheels and a steering postserving to support the frame, and means to adjustthe frame on the steering post to vary the height of the seatfor children of different sizes. a

A, further feature is'to so mount the seat on the frame structure that the seat will hinge on one part and slide on another part of the structure, but will at all times be held ina substantially horizontal position and in a posture to receive the user.,

A further-feature consists in providing a car of the tri-cycle type which will always be stable and upright,- and in this connection, the invention includes a supporting frame 0f A-f01mati0n with the rear-1; b terminals supported by hearing wheels, and the front apex attached to' the steering "post, a seat frame extending, from its point of attachment with the steering post upwardly between the limbs of the supporting frameto which it .i's'pivoted, and the seat being secured to the seatframeiand slidable on the supporting frame: Thus when the. supporting frame is" adjusted on the steering post,

the seat is raised .or lowered as the case may be.

' This invention includes other features and objects which will be more fully described in connection with the accompanying drawings and which will be more particularly pointed out in and by theappended claims.

- In the drawings I Figure 1, is aview in side .elevation of the improved childs car adjusted to the maximum height.

Fig. 2, is a plan View thereof.

Fig. 3, is a view similar to Fig. l, with a maximum low adjustment.

Fig. 4, is a detail view showing the manner of uniting the seat frame with the sup porting frame.

' 2 Fig. 5, is a detail view showing the I shoulder engagement of the front of the seat with the limbs of the-supporting frame.

. Fig. 6, is a sectional view on line 66-of Fig. 5. a I

I Like characters of references designate similar parts throughout the different figures of the drawings.

4 As illustrated, 1 designates a steering post whichis forked at 2 to :receive a bearing wheel 3, the wheel 3 being journaled on an axle 4. The post 1 isprovided with foot rests in the form of t-runnions 5 which serve to support the feet of the user in coasting. A plurality of adjusting holes 6 is provided for a purpose which w ll presently appear. Near the top oftheqo'ostl, hand grips 7 are provided to enable the user to steer the car.

A supporting frame is'indicated at 8, and when the car is of the tri-cycle type as shown, the frame 8 is of A-shaped form, the

terminals 9 ofthe limbs being preferably secured to an axle member 10. Bearingwheels 11 support the rear portion of the frame structure and the same may be j ournaled on the axle member 10 by screws 12. At the apex of the supporting frame is secure means, the function of which is to pivotally unite the suporting frame with. the steering posti-n any position of adjustment selected. As shown, an eye member 13 is secured to the apex 1 1, and an eye member 15 is linked with the eye member 13, to form a pivotal connection. },Eye member 15 has a shank 16, adapted'to be extended through any one, of

.the holes 6, in post 1, to vary the inclination of the supporting frame 8. Means such as a cotter pin may serve to anchor the shank in its adjusted position. I

A seat frame is provided which is shown in the form of a bar '17, the same being relatively wide at its rear end 18 and tapering toward its front end 19. The bar 17 is interposed between the limbs of the frame 8 and is pivoted thereto at 20 so thatthe two frames are somewhat on the order of a scissors formation. I The front end 19 is provided with an eye 21 which is linked with an eye 22, fixed to the post 1, whereby the seat bar is pivotally attached to the steering post 1 in a manner to freely permit steering adjustment of said post. The disposition of the frames is such that the forward end of the seat frame is the low end and the forward end of the supporting frame is the high end. Thus, the rear or high end of the seat frame will always project above the low end of the supporting frame.

A. seat 23 is secured at its rear end to the seat frame, such as by a hinge 24:, whereby the seat may have slight movement with respect to the seat frame 17. The front end of the seat 24 rests on the supporting frame 8, and this front seat end is shouldered at 25 so that the reduced portions 26, one on each side, will rest on the limbs of the supporting me while the tongue 27 projects downwardly between the limbs.

The parts are so proportioned and arranged that when the supporting frame is adjusted high, the seat '23, at itsforward end, will slide on the A-frame into the position shown in Fig. 1, but will always assume a substantially horizontal position, the same being true in the low adjustment shown in Fig. 2. Furthermore, in any adjustment, the hand-grips 7 will always be substantially the same distance from the seat 23, because the post l inclines more toward the seat 23 when a lower adjustment is effected.

It will be seen that that portion of the frame structure comprising frames 8 and 17 are of substantially scissors formation, and

.that when adjustment either high or low is effected, the frame structure is equally strong, and stable. w

It is believed that the advantages and utility of this invention will be clearly understood from the foregoing description, and whileI have herein shown and described one form c-f my invention, I do not wish to be limited thereto, except for such limitations as the claims may import.

I claim':-
