UNITED STATES JOHN BENGTSON, OF CHICAGO, ILLINOIS.

BED MOUNTING.

Application filed May 27, 1927. Serial No. 194,751.

There is a popular demand for beds so mounted and constructed that they may be housed in an upright position in a closet or other small space,'when not in use, and be swung clear of the'closet when brought into a horizontal. service position. The object of the present invention is to produce a simple and novel mounting for a bed structure, whereby the latter may be swung between an upright position and a horizontal position, in

either direction, with little effort, the bed travelling horizontally a considerable distance in shifting it from one position to the other, whereby the bed may be stored in the closet or the like in an upright position when not in use and be swung completely out of the closet when horizontal.

If the structure as a whole is mounted on casters, it becomes a roll-away bed and therefore, viewed in one of its aspects, the invention may be said to have for its object to produce a simple and novel mounting for a bed of the roll-away type.

The various features of no elty whereby my invention is characterized will hereinafter be pointed out with particularity in the claim; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein: I

Figure 1 is a side View of my improved bed occupying its horizontal position; Fig. 2 is a view similar to Fig. 1, the bed being in a vertical position; Fig. 3 is a plan view, on a larger scale, of a fragment of the struc ture, and Fig. 4 is a section taken approximately on line 44 of Fig. 3.

Referring to the drawing, 1 represents one of the side rails and 2 and 3 portions of the head and foot, respectively, of a bed of any usual or suitable construction. In the arrangement shown, the head member of the bed has a folding section 4 at the top while the foot member has a bottom swinging or folding section 5, this construction be ng similar to that disclosed in the application of Charles L. MacIntosh filed March 2, 1927, Serial No. 171,933. Furthermore, the swinging sections 4 and 5 may be moved automatically by means of devices such as employed in the MacIntosh bed, such devlces being actuated by one of the swinging elem'ents, conveniently the bar 12 to be hereinafter described. A bed-supporting arm 6 is pivoted at its lower end to the front end of a base member 7 and has at its upper end a roller 8 rlding in a slot 9 extending lengthwise in the adjacent side frame member 1.

If this frame member consists of an angle iron, the slot may be formed by securing underneath the horizontal flange of the angle iron a bar 10 in the form of a flattened U.-

The head end of the bed is connected to an upright part or post 11 of the base member/(by a bar 1 2 in the form ofa flattened V, the connection between this bar and the part 11 being at a considerable elevation from the floor. Between the member 11 and the arm 6 is a flexible connection, consisting convenientlyof two links, 13 and 14, hinged. together and pivoted, one to the member 11 and the other to the arm 6. At the joint between the links 13 and 14 is a roller 15, preferably having a peripheral groove, disposed in the plane of swinging movements of the bar 12. A strong spring 16 extends diagonally downwardly and away from the bed frame to the base member.

When the bed is swung into its horizontal position as shown in Fig. 1, it is supported at the head end from the arm 6 and the bar 12, the latter resting on the roller 15. The downward pressure on the bed end of the bar tends to cause the bar to force the roller 15 down and thus swing the upper end of the arm 6 toward the left. A state of equilibrium is reached when the roller on the arm 6 arrives at the left hand end of the slot within which it plays. The spring is now under considerable tension. When the bed is to be swung into its upright post tion, the foot end is lifted, thus swinging the bed as a whole about the roller 8 as a pivot, the head end moving downward. This movement is aided by the spring 16. However, any downward movement of the head end of the bed results in swinging the bar 12 down and pressing down the roller 15, so that the arm 6 must swing toward the left. As the upward movement of the foot end of the bed continues, the arm 6 is brought into an upright position, with the roller 8 in the opposite end of the slot 9 from that in which it lies in Fig. 1, one arm of the bar 12 assuming an approximate- 1y vertical position, and the other arm which is the one pivoted to the bed, assuming an approximately horizontal position directly above the base.

The upper end of the arm 6 is bent back with respect to the remainder of the arm,

as indicated at 17, so that when the bed is in an upright position, the main portion of the arm 6 stands up outwardly from or in front of the bed and the weight of the bed is therefore exerted in a direction to hold the bed upright.

There will usually of course be two of the supporting mechanisms, such as I have described, one at each side of the bed; or, the base may be as wide as the bed and be provided at each end with a set of arms and bars and links. The number of such mech anisms is not important, however, since the feature of my invention has to do with a supporting structure made up of a few simple elements and a spring, that will permit a bed to be swung up and down, while countor-balanced, and to be moved bodily through a considerable distance in the direction of its length while passing between its upright and its horizontal positions.

While I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the definitions of my invention constituting the appended claim.

I claim: t

In combination, a base having at the rear end an upright post, a bed adapted to be positioned in front of the base when horizontal, a bar pivotally connected at its ends to the post and the adjacent end of the bed, an arm pivoted at its lower end to the base and extending upwardly and forwardly to the bed when the latter is horizontal, means connectingthe upper end of said arm to the bed for sliding movements for a limited distance in the direction of the length of the bed, a flexible connection between the post and an intermediate point on said arm, and cooperating elements on said bar and said flexible connection to cause the latter to be flexed in a direction to swing said arm toward an upright position when the remote end of the bed is lifted.

In testimony whereof, I sign this specification.

JOHN BENGTSON.
