CHILDS CHAIR FOR AUTOMOBILES Filed Sept. 11, 1950 INVENTOR. ARTHUR E. SINGLETON ATTORNEY Patented Apr. 13, 1954 UNITED STATES PATENT OFFICE CHILDS CHAIR FOR AUTOMOBILES Application September 11, 1950, Serial No. 184,177
(Cl. 155--l1) 3 Claims.
This invention relates to improvements in looking mechanism for a childs auxiliary chair for automobiles of that type usually positioned in connection with the seat cushion and the backrest cushion of an automobile.
One of the objects of the instant invention is simplification of the locking means for securing the chair in place.
And another object of the invention is to construct the locking mechanism so as to be more readily manipulated in adjusting the chair into operating position and removing it therefrom.
Other objects and advantages of the invention appear in the following description.
An illustrative embodiment of the invention is shown in the accompanying drawings, in which:
Fig. l is a side elevational view of a structure incorporating the invention, shown in locked position;
Fig. 2 is a front elevational view, portions being in section approximately on the line 2-2 of Fig, 1; and
Fig. 3 is a perspective view showing one of the chair seat supporting frames including the locking means therefor in locked position.
The illustrative embodiment of the invention consists of a pair of supporting frames, indicated generally by A, upon which the chair seat 4 is secured in the usual manner, each having forelegs 5 and corresponding rear legs 6. In the lower end of each rear leg 6, at its juncture with the bottom span 1 of the frame, is made a vertically elongated slot 8, and a similar slot 9 is made in the frame at the juncture of the foreleg 5 with the span 1 alined with the slot 8.
In each frame is disposed a base member I consisting of a rod that has longitudinal sliding movement in the frame through said slots and has in its midportion a downwardly inclined crook II that acts as a stop to limit forward movement of the base member in the frame A by having contact with the inner face of the foreleg thereof. To the underside of the base member H) is secured a key l2 that extends parallel therewith rearwardly from a point adjacent the crook, through the rear slot 8, and terminates at a point adjacent the rear end of said member. The front end of each base member has a forwardly extending portion I3 that has a bent end It constituting a handle by which said member is manipulated. The rear end of the base member i0 is bent substantially in a plane at right angles to the handle I4 to provide a hook l5 suitable for engagement with the automobile seat cushion 16 when the chair is in place.
Upon the inner face of each rear leg 6 is secured a jam-spring I! the free end of which normally impinges against the base member thereby preventing forward movement of the frame relative to the base member. Upon each rear leg 6 is a lever [B hinged in a notched portion of leg 6 as indicated at Ill. The lever has an opening 20 through which the corresponding jam-spring ll passes, the parts being so arranged that, upon raising the lever, the spring is cammed out of engagement with the base member by the rear wall of opening 20, thus permitting the chair to be moved forwardly out of operating position.
Operation In utilizing the invention, the hinged levers l8 are swung upwardly thereby camming the jamsprings ll out of engagement with members l0, after which the base members I!) are shoved rearwardly in the leg frames so the keys l2 pass completely through the rear slots 8 thereby permitting the base members to be rotated in the leg frames which is accomplished by turning the handles M vertically upward resulting in movement of the hooks [5 into horizontal posi tion. The chair while resting on the cushion is then moved rearwardly so the hooks l5 become inserted between the seat and back-rest cushions. By returning the handles M to horizontal position, the hooks 15 are moved into holding engagement with the rear part of the seat cushion, after which swinging the levers is down-- wardly, the jam-springs again are permitted to engage the base members thereby to prevent forward movement of the leg frames on the base members. By then shoving the chair rearwardly against the back-rest cushion it is there held firmly in operating position by the locking mech anism.
Removal of the chair is accomplished by swinging the levers upwardly which cam the jamsprings from engagement with the base members, moving the chair forwardly, and then turning the handles into vertical position to cause disengagement of the hooks from the seat cushion thus permitting removal of the chair over the seat cushion.
The operations of positioning the chair in place and removing it from the automobile is accomplished conveniently by simple manipulation of the handles on the base members and the hinged levers on the rear legs.
What I claim is:
1. In combination, a childs auxiliary auto chair comprising seat supporting frames having front and rear legs and base members slidably supported in said legs, and a locking mechanism consisting of jam-springs secured to the inner faces of the rear legs of the seat supporting frames and normally projecting into locking engagement with the base members, and hinged levers on said rear legs having openings therein through which said jam-springs extend respectively in freely movable relation, said levers being movable springs, for moving said jam-springs from looking engagement with said base members.
2. In combination, a childs auxiliary auto chair including a, pair of seat-supporting leg frames each of which comprise a front leg and a rear leg and sliding base members in said leg frames for securing the chair in place, a locking mechanism consisting of jam-springs secured to the inner faces of the rear legs of said seatsupporting frames and which are preformed to normally engage the corresponding base memhers to prevent movement thereof in one direction relative to said frames, and levers hinged on the rear legs of said frames and having openings therein respectively through which the corinto positive engagement with said 4 responding jam-springs extend so that upon raising the levers said jam-springs are thrown out of engagement with the respective base memhere.
3. For use in combination with a childs auxiliary auto chair comprised of front and rear seatsupporting legs and sliding base members mounted therein for securing the chair in place, locking mechanism mounted on the rear legs out of reach of the occupant of the chair, said locking mechanism consisting of jam-springs secured to the rear legs and normally biased into locking engagement with said base members and hinged levers having openings therein through which extend said jam-springs respectively, movement of said levers serving to move said springs out of locking engagement with said base members when moved to a selected position.
