Application filed. October 29,. 1923. Serial No. .671,38 5.

in av metal folding bed of this 'cl'iaracter, a. stabilizer for preventing the overturning of the bed structure :upon the person open ng same and for counter-balancing the bed structurein such a manner that it. will remain in anyposition intermediate of the closed and opened position thereof and may be raised and lowered with the expenditure of. very little effort. WViththeordinary type. offolding bed, in which springs-are stretched between the bed frame and the carriage for the purpose of maintaining the bed in raised position, a carriageof considerable width must be employed, 'otherwise'when it is at tempted tolower the bed from vertical position, the. carriage will tip up, often causing thebedto over-balance and fall upon the person operating same. f

The invention employs as a stabilizer, a leg member pivoted to the bed frame at an intermediate point in such a manner that when the bed is lowered, the lower end of the leg will ride outwardly, and springs acting between the stabilizer leg and the bed frame .in a manner to" resist the outward movementjof thestabilizer leg, thus institut ing resisting force against the weignt of the bed frame as it swings downwardly from raised position. V

It is an additional object'of the invention to provide .foldable track leg for. receiving and guiding the lower end of the stabilizer leg as it swings outwardly.

The especial ad ant-ages of the invention and further objects thereof will be made. evident hereinafter.

Referring to the drawings which are for illustrative purposes only.

vention is particularly adapte cOl1S1-3i30fi carriage 11 having wheels 12. and a bed frame 1;} pivoted at l lfFigs. 1 and 3, on a cross-bar 15 whichextends between the end. castings 1 8 of the carriage 11. The castings c5 18 of the carriage 11 areheld' together by the bar 15 and av lower bar120 which maybe hollow pipe or of solid material as desired. The bed frame 13 iscomprisedof side-men bers 22a-nd end members 23 between which a spring fabric 24 is stretched. The particular structure. is 'arranged to swing on the pivots 14 between the raisedyposition shown in -1 and the lowered position shown in F llear the center: of the bars 15 and I 20, a pair of castings 25 are mounted as shown inthe drawings, these cas ings supporting ahanger plate 27 which is of U shape, by. the use of bolts 28 extending through theflanges 29, of the'channel or U shaped member 27. On the bottom or web portion 31 of the member 27, a-track member 32 is secured by screws 33, this track me nbe]: consisting of a channel bar having the flanges thereof'upwardly disposed and ha-ving a perpendicularly projected plate or toe Matthe inner end thereof. When the bed frame 13. is i nraised position, the track member 32 maybe swung upwardl on the pivot bolts 28 into the position .siown in '90 Fig- 1'- p ingrinemb 3 Fig. 4,. are atached .b jplates 3.6 to eccentrically dispos d pins 37 sot-hat the tensionof the spring will be exerted above the pivots28 when the track member is inzraised position, thus holding it against ,falling,a11d will be exerted below the pivots 28 when the track member is in lowered position. ,Upon pivot-s 40, consisting of bolts'or'rivets asdesired, situated at intermediate ositionsfon t-he side bars of he ed irea tQ i iZ rJQs'eZ send ing of a flat bar bent into the .blflb ted form {shown in the drawing. shown Figs. dandfi, angle brackets are; riveted at 412 to the intermedia e.:poi .of the leg -/.&2 and have the purpose. ofsupporting a. shaft 45 upon which a wheel 46 is mounted. This 'wheel 46is arranged to ride in the track 32 between the position shown in Fig. 1 and the position shown in Fig. 2. 'When the track is in raised position as shown in Fig. 1, the wheel 46 rests on the plate 34:v and the lower end of the track member 32 extends upwardly across the forward edge of the wheel and serves as a lock against outward move ment of the wheel and therefore a lock for preventing the bed from being over-turned. When it is desired to lower the bed from vertical position, the track 32 is swung downwardly into the position indicated in dotted lines 50, Fig. 1, or in full lines in Fig. 2, traction means consisting of acaster 51 preferably not at but near the outer end of said track and resting upon the floor then serving to support the said outward end of the track member 32.

It will be plainly evident that the bed may be wheeled about when the track memher lowered with the same case as when the track member is in raised position owing to the wheel support 51. As the bed is swung dowmvardly from the raised position, the wheel 14:6 moves outwardly in a direction of the arrow (50, Fig. 1, along the track 39, thus causing the stabilizing leg 42 to swing outwardly upon the pivots l against the action of tension springs and U3 which extend between the head cross member 23 and links secured through holes in the bifurcated ends of the leg l2. The resisting force exerted by the spring 62 and 63 against the outward swing of the stabilizing leg 4-2 increases proportionately with the outward movement of the member l2 which movement depends upon the downward swing of the bed frame 13, so that the resisting force applied by the springs is proportionate to the downward force exerted by the weight of the bed frame in its various positions of unfoldment.

I Cltlll'll as my invention:

1. In combination: a supporting structure; a bed frame pivoted on said structure; a stabilizer leg pivoted at an intermediate point to said bed frame; resilient means operative to resist the outward swing of said stabilizer leg; and a track arranged to receive the pressure of, and guide the lower end of said stabilizer leg, said track being l'oldable between upright position against said bed frame and laterally extended position. i

2. In combination: a supporting structure; a bed frame pivoted on said structure; a stabilizer leg pivoted at an intermediate point to said bed frame; resilient means operative to resist the out-ward swing of said stabilizer leg; and a track arranged to receive the pressure of and guide the lower end of said stabilizer leg, said track being fold-able between upright position against said bed fame and laterally extended position; and traction means near the free end of said track for supporting the end of said track when said track is laterally extended.

2-3. In combination: a supporting structure; a bed frame pivoted on said structure; a stabilizer leg pivoted at an intermediate point to said bed frame; resilient means cperative to resist the outward swing of said stabilizer leg; and a track arranged to receive the pressure of and guide the lower end or" said stal'iilizer leg, said track being fold-- able between retracted posit-ion within the vertically projected area of saidsupporting structure and laterally extended position; and traction means for supporting the end of said track when said track is laterally extended.

In combination? a supporting structure; a bed frame pivoted on said structure; a stabilizer leg pivoted at an intermediate point to said bed frame; resilient means operative to resist the outward swing of said stabilizer leg; and a track arranged to re ccive the pressure of and guide the lower end of said stabilizer leg, said track being :loldable between retracted position within the vertically projected area of said supporting structure and laterally extended position; and spring means acting on said track eccentric to the pivot thereof so as to hold said track in upright or extended position; and traction means for supporting the end of said track when said track is laterally extended.

In COITlblDtlillOIlZ ture; a bed frame a stabilizer leg a supporting strucpivoted on said structure; pivoted at an intermediate point to said bed frame; resilient means op-y erative to resist the outward swing of said stabilizer leg; and a track arranged to re ceive the pressure of and guide the lower end of said stabilizer leg, said track being foldable between retracted position within the vertically projected area of said sup porting structure and laterally extended position; spring means acting on said track eccentric to the pivot thereof so as to hold said track in upright or extended position; and a caster near theouter end thereof for supporting said track when said track is laterally extended.

In testimony whereof, Ihave hereunto set my hand at Los Angeles. California, this 220th day of October, 1923.
