FOLDING BED.

Specification of Letters Patent.

Patented Jan. 25, 1921.

Application filed February 11, 1918. Serial No. 216,505.

To all whom it may concern:

Be it known that I, LAURITS HANSEN One of the objects of my invention is to produce a folding bed which is self supporting, that is, one which may be detached from any base or frame and moved about the floor as desired, in the same manner as ordinary beds.

Another object of my invention is to provide a folding bed which, when so detached from its inclosing casing or frame, will be locked against possibility of collapsing and will be unlocked for folding by engagement with the inclosing or storing casing or frame.

Another feature of my invention is to provide means for securing the bed frame to its storing casing or frame and other means whereby said securing means will be locked against release whenever the bed is folded, this locking being automatically secured by the act of folding the bed.

Other obj ectsof my invention may be seen from a study of the specification and the drawin s, and the particular combinations upon which I desire patent will be particularly set forth in the claims.

In the accompanying drawings I have shown my invention in the form of construction which I now most prefer.

Figure 1 is a side elevation of the bed in opened position and secured to its storing casing, the casing being however in section taken just in front of the bed.

Fig. 2 is a similar View showing the bed in folded or closed position.

Fig. 3 is a head end elevation of the bed removed from its storing case.

Fig. 4 'is a section on the line 4;, 4 of Fig. 5. i 7

Fig. 5 is a plan view with one pipe in section showingthe parts shown in Fig. 4.

Fig. 6 shows the relation between the locking features on the bed and the related parts upon the casing, particularly the manner of releasing the non-collapsing lock.

Fig. 7 is a section on a plane lengthwise of the bed frame showing the construction of the head piece.

Fig. 8 is a sectional elevation taken transversely of the bed through the head piece.

Figs. 9, 10 and 11 are detail views showing a slightly different mechanism.

The bed frame 1 may be, in the main, of

any standard construction, consisting of a rectangular frame having springs secured therein. Head posts 2 are employed, these being connected at their lower ends by a bar 20-which is preferably close to the floor, thus leaving the space between the posts 2 clear of any obstruction. The upper ends of the posts are connected by parts which will be later described. Rollers 21 are shown in the lower ends of-the posts. For convenience in guiding the bed back into position for putting it into the storing case or frame, these rollers had best not be provided with any vertical pivot support.

The bed frame is supportingly connected with the posts 2 by two links 3, pivoted at 31 to the bed frame and at 32 to the posts A link 4 is pivoted to the head corner of the bed at each side. At its pivot is placed a roller 40 which engages the side of the post which faces the foot of the bed, and a similar roller 41 mounted on the end of the link engages the opposite side of the post. These act in conjunction with the post 17 to guide the head end of the bed when raising and lowering.

At the head end of the bed is journaled a shaft 8 to which the links 1 are secured. Surrounding this shaft are torsion springs 80, one end secured to the shaft and the other to the frame. These are so adjusted that they have an initial tension acting to raise the bed and hold it folded. I provide a shield for these springs consisting of the semi-tubular plate 81. The rollers 40, 41, form guiding or bearing members for the head end of the bed.

When the bed is swung upwardly, or toward the closed position, these rollers travel down the post until the upper roller 41 enters the seat 42 in the bracket 44, which is engaged to the wall 15, which is part of the storing case or support for the bed when it is folded. This contact occurs before the bed reaches its'upperniost or folded position, orthat shown by broken lines in Fig. 2; further upward movement of the bed will cause the links 3 to raise the posts 2 from the floor, as is shown in Fig. 2. The bracket 4141 has'a finger 43, which engages the outer sicke face of the post 2 to insure its accura e position in the storing frame.

The upperends of the posts 2 are connected by a bar 5, through side arms at its ends. These arms 50 terminate in flat pivot ears 51 and the upper ends of the posts 2 in like'pivot ears 24-, these being connected by pivots 25. V

The vertical wall l5 of the bed-receiving or storing case, has two brackets 6 adapted to enter just inside of the arms 50. These are at such a height that when the bed is opened, the posts 2 re onthe floor and the arms 50 extend upward, as is shown in broken lines in Fig. 1, to such a height that the bar 5 will just pass over the horn or curved upper portion of them-ticket. When the bar 5 is swung down by hand into the" position shown in full lines in Fig. 1 the bed is held against removal from the wall 15 of the storage case or closet;

Carried by the swinging rail or bar 5 is a short arm 55, which has a short, horizontally projecting pin 56 in position to enter the slot at the base of the bracket 6 when the bar 5 assumes the position shown in Fig. 2; This it will automatically do when the posts 2 are liftedby folding. the bed, due to the fact that theweight of the bar .5 will prevent its rising when the posts are 7 raised, thus changing the angle of the arms 50 to swing the pin 56 into the slot 60. In this positioniit is impossible to detach the bed; The bed therefore can only be deftached from its storing case after it has ;been opened. r

The head end of the bed has upwardly extending arms 10 fixed rigidly thereto.

These are only of such length as may be accommodated in the'stormg case when the bed is folded. It may be provided with cross bars 12 and 13 and these be cross connected in any manner desired;

An extension head section 17 is pivoted at 16. The pivot hinge 16 is so constructed that when head section 17 is swung upward it engages stud or pin 33 on link 3, which link in turn is secured to-post 2 at 32, see

Fig. 7. This fixes the position of bed frame 1 in relation to posts 2 and, in connection vvlth the engagement of roller 10 with stop bracket 28, see Fig; 2, forms a rigid three point connection posts 2. H

The extension head section has a top bar 18, the ends of which project close to the posts 2; I provide means for engaging and holding this when it is raised, thereby preventing foldingof the bed. Two forms of between bed and head devices forthis are shown. That shown in having its outer side face inclined to be displaced byengagement therewith of the end of bar 18, the hook'then engaging the bar 18 to prevent its return until the spring dog or look is manually released. I prefer to use the hook 34: at only". one side of the bed as it would be diiiicult to manually release twoof them. 4

The radial arms 50 have therein a locking dog 53 which hasa laterally extending arm occupying the'interior of the main tube or bar 5, this having an ofisct which may project through a hole in the inner side of bar 5. The two fiat ears 2% and 51 have notches 26"and 52 which will come into registry when the connecting bar is swung upward into line with the posts 2. 7 he locking dog 53 is at this timein'position to enter both of thenotches 25and 52, thus locking the bar in its raised position, or. as shown in Figs. 3 and 6. The end of the bar 18 is securely held by the a cuate flange 58 and the spring dogs 3 1, Until this has, been released, the bed cannot be folded. While so held the head pieces 17, 18, act as a tie, connecting'the head end of the bed frame with the cross bar 5, and preventing the lowering of the head of the bed, which lowering is necessary in folding the bed. This prevents thepossibility of collapsing the bed while disengaged from the storing frame. There are two of the locking dogs and it would be diiiicult for one person to release both at once'by direct manual en dogs out'of thenotclies26and52, thus releasing the bar 5 and permitting it to be swung down to therebylsecure the'bed'to the storingand carrying member 15, and'to" permit folding of the bed;

' V The locking device. shown in Figs. 9, 10 and 11,12 sim lar in ts principle and opera tion,but somewhat different in construction.

7 The flat ear 2 1 ofthe postgwhich ishere placed inside of the corresponding member 51 of the arm 50, has an inwardly projecting,arcuate flange 27, and an armo which is hinged on the bar 5, has, an arcu'ate or semi-tubular flange 70, which is notched on the side next to the post to form a projecting ear 71, positioned to clear the flange 27 when the parts are in the position shown in Figs. 9 and 10, and to swing under the flange 27 when the bar is swung upward;

When the bar 5 is swung downward and backward, or into the position shown in full lines in the figures, the hook arm 7 has its curved flange 70 engaging the ends of the bar 18 to prevent movement thereof forward or backward. When the bar 5 is swung up, the curved flange 71 turns under the arcuate flange 27 and locks the hook arm 7 and prevents movement of the bar'18 downward, or in the direction which is necessary in order to fold the bed. It, therefore, constitutes a non-folding look.

When the bed is folded, the hook bar 7 drops downward, into the position shown by broken lines in Fig. 9. The pivot sleeve 7 71", by which the arm is mounted on the bar 5 has a diagonally positioned slot 73, Fig. 11. A pin 72 passes through this slot 73 and through a slot in pipe 5, which latter slot is parallel with the axis of the pipe, and is fixed in a short bar 74 which is slidable within said pipe. This short bar, which is free to move lengthwise of pipe 5, has a pin 7 which projects through a slot 76 in pipe 5, which slot is also parallel with the axis of the pipe.

In consequence of the diagonal position of slot 73 in sleeve 71, rotation of arm 7 will cause an endwise movement of bar 74. The direction of slot 73 is such that a downward movement of hook bar 7, causes an inward movement of bar 74 and moves the pin 75 under a lug, or pro ection 63, on bracket 6, so that the bar 5 which passes over bracket 6 and locks the bed to its stor- :2 ing up on bracket 6, when in the act of foldframe.

ing the bed, the posts 2 are raised.

In using this kind of a lock 1 contem-' plate'applying it only to one side of the bed and using the locking plunger 53, of Figs. 4: and 5, at the other side. In consequence, the hook 7 can only be released by first releasing the lock 53 ant this can only be released by securing the bed to its storing frame.

The legs 9 at the foot of the bed are provided with a flat head 90 having a vertical slot through which. passes a securing pin 93, so that the legs may have a certain amount of vertical movement. A complemental abutment 9 is rigid with the bed The two parts 90 and 94, have inclined abutting surfaces or edges, which are crowded together by downward movement of the bed frame, the pin 93resisting down and hinge to fold against the bed frame, after the manner shown in Fig. 2.

It may be noted that the bracket or arm 10 of the head of the bed frame, has a notch 11 so positioned that when the bed is fully folded, it accommodates the cross bar 20 which connects the bottom of the posts 2.

lVith the bed in folded position, the first thing to do is to swing down the foot of the bed. As the support of the bed is well toward the bottom of the bed frame, or the side which is out when folded, and as the springs 80 also act to keep it folded, there is no need for a lock.

As the bed approaches the floor the posts 2 are lowered until they rest upon the floor. The weight of the bed is thus taken off of the storing frame 13. The head piece of the bed is then swung up, this being locked in place by the catch 53 or the hook 7, whichever is used. There is then no chance for the bed to be folded, either accidentally or purposely, except after the head piece has been released.

If it be desired to remove the bed from its storing case, the bar 5, which connects the upper ends of the posts 2, is swung upward, until it reaches a vertical position, in which position the locking bolt 53 will enter the slots in both of the disks 24 and 51, thus preventing further movement in either direction.

The bed is then free to be moved wherever desired and is held against collapsing. Furthermore, to release it it must be brought back to its storing case to release the lock bars 53 by engagement thereof with the inclined faces 62 of the horns 6. \Vhen the bed is folded, the posts 2 will be raised, thus engaging the pins 56 in the notches 60, so that it is impossible to remove the bed from its storing case until it has been opened and also looked against collapse.
