me nts. For this purpose a linkage is provided,-

ing myinvention comprises a fixed frame and a frame supported independently of the fixed frame and movable from, a retracted position under the fixed frame to an extendedposition alongside and at an elevation common with thefixed frame.

Means are provided connecting the frames together for guiding the movable frame in its extending and retracting movements. Means are also preferably provided for urging the movable frame toward its extended position, and a latch is preferably provided for holding the movable frame in its retracted position. A base is provided for supporting the movable frame, and the latter is mounted on the base so that it is movable from-a collapsed position on the base to an elevated position above the base; the collapsible feature-of the movable frame on its base being provided so that the-.movable frame may clear the fixed frame when in its retracted position under the latter. Means are also provided on the base,

operable upon movement 'of' the frame to its elevated position, for holding the same in said elevated position.

In greater detail, and referring particularly to Figures 1 to '7, the preferred form of bed embodying my invention comprises a body section 2 and an independently supported foldable section 3. The body section 2 comprises a fixed spring frame 4 held by a suitable supporting structure including floor engaging legs 6. Y

The foldable section 3 of the bed comprises a spring frame 7 which is movable from a folded or retracted position under the fixed frame, as shown in Figure 1,.to an open or extended positionalongside and atan elevation common with the fixed framaias shownin Figure 4. The foldable. bed section 3 also includes a base 8 for supporting the movable frame 7. The base 8 is preferably in the nature of a box in which bedclothe. ing maybe stored. To afford mobility and to provide independent support for the frame '7, the

base 8 is mounted on .suitablefloor engaging rollers 9. I

Means are provided for guiding the foldable section 13 in its extending and retracting move-.

preferably comprising a pairof crossed equalizing arms- 11 These arms are pivoted. together adjacent their center, and each is pivoted at.

one end to the supporting structure of the body section 2 and at the other endto the base 8l'of.

thefoldable section 3. One of thepivots at the end of each of the arins is allowed to work in a lfl... slot, a 15 0 2 1 Practice i an equalizing linkag izof this type.

The pivots at 118f I the junction of the arms 11 and the body section 2 are preferably of a permanent nature, while the pivots at the junctions of the arms and the folding section 3 are preferably such that they 5 may be readily released to disconnect the bed sections.

As best shown in Figure 2, the junction between the arms 11 and the section 3 is preferably effected by providing a socket 12 on the base 8 into which a piv'otpin'13 on an arm 11 may project. To free the arm it is only necessary to lift the pin 13 from its socket. By this construction the two sections of the bed may be readily connected and disconnected, which is an important feature 15 in connection with the transportation of the bed.

Still referring to Figure 2, the equalizing arms able section 3in its retracted position, as shown in Figure 1. As best shown in Figures 6 and '7, this latch preferably comprises a hook 18 pivoted on'the base 8 and engageable with a complementary hook'19 on the body section 2. The

hook 18 is released by a push button 21 positioned "on the front end of the base 8. As shown in Figure 7, the button is mounted on the end of a lever 22 connected'to the hook 18 by a suitable rod 23. A spring 24 is provided for holding the latch engagement. In order to extend the foldable sec- "tion of the bed it is merely necessary to press the button 21.

As best shown in Figures 1 to 4, the movable spring frame 2 of the foldable bed section 3 is mounted on its supporting base 8 so that it may to an elevated position where it lies in the plane defined by the fixed spring frame 4 of the body section 2.

pivotally and'slidably mounted on the base 8. ""This is effected by suitable hinges 26 which are' fixedto the frame? and slidably connected to the base 8.; As shown in detail in Figure 5, the upper wing of a hinge-26 is securely fastened-to the frame 7, while the lower wing of the hinge mounted on a plate 29 which is fastened to the base 8. I 7 V Spacing means are provided for holding the frame: '7 in its elevated position. To this end a bar 31 is provided at each end of the base-8 and is pivotally connected to a flxed element 32 secured to the base by means of a pair of parallel arms 33. A spring 34 connected between one of the arms 33 and the fixed element 32 is arranged """to urge the spacing bar 31 toward its raised position, and a stop pin 36 is provided for holding the bar in this position. The spring 34 is suffit hb 1 thldth. Clently heavy 0 t 8 ar 3 and 0 o e raise the spacing bars. The bars are held against downward movement in the present instance by sa me against the forward thrust of the frame 7 in the final act of elevating the frame, as will be understood from the following.

Considering the mechanism thus far described,

the actions 'involved in elevating the movable frame -T are as follows nn operator grasps 'the' "forward edge of the frame 7 andswings the same "be moved from a collapsed position on the base Preferably the movable frame '7 is is provided with a slot" 2'? engaged bythe studs 28 up to a position as shown in Figure 3. 'As' the frame swings out it is followed up by the spacing bar 31 due to the action of the spring 34. The operator then allows the frame '7 to swing down again. During this downward swing the frame moves into engagement with the spacing bars 31, and subsequent movement is a hinging of the frame about the rear ends of the bars. This latter movement ispermitted byan upward sliding of the hinges 28.

When the frame finally comes to rest it is supported by the spacing bars 31, as shown in Figure 4. Of course the links 33 of the spacing bars are of such length that the frame 7 is at the same elevation as the fixed frame 4 of the body section 2. It will be seen that the elevating of the frame 7 is accomplished by two simple motions imparted by an operator, namely, swinging the frame '7 up and then letting it down again.

Means are provided for effecting a collapsing of the "frame '7 to its position as shown inFigure 2, so that the folding section 3'may be retracted into the body section 2. For this purposea link 38 is provided at each end of the frame '7 pivotally" connected at one end to the frame andslidably pivoted at the other end to the spacing bar 31 in 'a' suitable slot 39.

42 on the end of the arm 38 may drop. j

The actions in collapsing the frame '7 from its of the frame is grasped by the operator and "is again swung up to the position shown in Figure '3.

This time the operator allows the frame '7 to swing back very slowly, so that the arm pin42 will drop into the recess 41.

of the pin '42 in the recess 41is onlynecessary in overcoming the inertia of the spring 34 and start; ing the spacing bar 31 down, the final collapsing'j of the spacing bar being effected by the frame 7 bearing down on the bar. 7 H g In order to prevent the pin 42 from engaging the recess 41 when the frame '7 is being raised "to hump 43 will cause the pin 42to jump over the the collapsing of the frame 7 also requires but two simple motions imparted by an operator,, namely, an up anddown swinging movement of the frame.

A modified form of the invention isshovvn 'in The lower edge of the slot 39 is j provided with a recess 41 into which the'pivot pin elevated position are as follows: The outer edge y no Having the pin' engaged in the recess, further lowering of the frame '7 causes the spacing bar 31to swing down, into its folded position. Of course the presence I Figures 8, 9 and 10. Here it will be observed that; a link 44 pivoted to the'fram'e 7 is slidably pivoted to the base 8 by means of a pin 46 workingin a guide groove 47. A notch "48 provided in the guide;

is arranged to receive the pin 45 for'holding the frame '7 in its upwardly tilted position.

In the present form the springs 34 ate to raise the spacing bars 31 are considerably lighter than those employed in the embodimentfirst described. In fact, the only function-pers formed by the springs 34 in the present case is" to an auxiliary mechanism such as shown in Figures 9an'd 10. "This mechanism comprises a pair-"of stop plates 'swung out to the position shownin Figure 9 the spacing bars 31 cannot return to their folded positions.

When it is desired to collapse the movable frame in this embodiment the lever 52 is actuated to swing in the stop plates 49, after which the operator swings up the frame 7 and then lowers the same against the bars 31 which causes the latter to fold down and allow the frame '7 to collapse against the base 8.

Relating to both embodiments of my invention, it will be noted that the foldable section 3 is being urged outwardly by the action of the spring 17 when the section 3 is in the retracted position.

' It will also be noted that in this position the bed springs in the frames 7 and 4 are in close proximity. When a person is resting on the folded bed the upper spring is pressed into contact with the lower spring This locks the two sections of the bed together, and the lower section will not extend itself, even though the release button 21 be accidently pressed.
