6 Claims. (Cl. 5-328) This invention relates to jacks and other elevating devices particularly adapted for raising objects above a oor to facilitate moving the objects laterally, and in par ticular a jack for elevating the foot of a bed with posts at the head of the bed positioned in slots in iloor plates whereby with the foot elevated the lbed is free to be moved laterally away from a wall or from another bed, such as twin beds to facilitate making the bed and Without damaging a rug or polished floor upon which legs or posts at the foot of the bed are positioned.

The purpose of this invention is to facilitate moving the foot of a bed laterally away from a wall or from another bed to provide access to both sides of the bed and to prevent damage to a rug or polished floor upon which the bed is positioned.

In numerous instances beds are positioned against a wall or twin beds are positioned together and it is difficult to make the beds without moving the foot laterally to provide space at the side of the bed. With this thought in mind this invention contemplates a jack having foot pedal actuated cams with a ball in a bracket depending from the foot of the bed positioned in a rail carried by the cams whereby with one end of the rail elevated by one of the cams the bracket is free to slide toward the `opposite end of the rail, and also floor plates having arcuate sl-ots therein in which posts at the head of the bed are positioned so that as the foot is moved toward the side the posts at the head of the bed follow in the slots preventing posts or legs at the end of the bed being drawn over rugs, polished oors, and the like.

The object of this invention is, therefore, to provide means for elevating the foot of a bed to facilitate moving the bed laterally.

Another object of the invention is to provide a jack for elevating the foot of a bed wherein the jack is provided with a rail upon which the bed is supported to facilitate sliding the bed with the posts at the foot of the bed elevated above the floor.

Another important object of the invention is to provide elevating means for supporting an end of a bed above the floor as the bed is moved laterally in which the device is adapted to be used on beds now in use without changing the design or construction of the bed.

A further 4object of the invention is to provide a jack for elevating the foot of a bed to facilitate moving the bed laterally in which the jack is of a simple and economical construction.

With these and other `objects and advantages in view the invention embodies a bracket mounted on and depending from an end rail of a bed, a jack having a rail with the ends supported by'cams positioned on the oor and set whereby the lower end of the bracket travels in the rail, floor plates having arcuate slots therein in which lower ends of posts at the head of the bed are positioned, and tie rods connecting the floor plates to the jack.

Other featuresand advantages of the invention will 2,862,213 Patented Dec. 2, 1958 appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a perspective view of a bed showing the jack positioned below the foot and floor plates with arcuate slots therein positioned to receive Iballs or casters on the lower ends of posts or legs at the head of the bed.

Figure 2 is a plan view of the jack assembly with the outline of a bed shown in the position for sleeping in full lines thereon and also with the bed in the position in which the foot is moved laterally in broken lines.

Figure 3 is a plan view of the bed elevating jack with the parts shown on an enlarged scale.

Figure 4 is a longitudinal section through the jack v taken on line 4-4 of Fig. 3 showing one end of a rail of the jack in an elevated position.

Figure 5 is a cross section through one end of the jack taken on line 5-5 of Fig. 4 also with the parts shown on an enlarged scale.

Figure 6 is a longitudinal section through the jack, with parts shown in elevation, said section being similar tot the section shown in Fig. 4 except that the rail is in a horizontal position Referring now to the drawing wherein like reference characters denote corresponding parts the improved bed moving jack of this invention includes a rail 10, U-shaped in Cross section with the ends resting upon cams 11 and 12 and positioned between uprights 13 and 14 at one end and 15 and 16 at the other end with the ends retained in arcuate slots 17 and 18 by

pins

19 and 20, respectively, a base 21 having an arcuate upwardly disposed ange 22 and in which the uprights are mounted,

treadles

23 and 24 for actuating the cams, oor plates 25 and 26 connected to the jack with

tie rods

27 and 28, respectively, and a bracket 29 having a ballor roller 30 in a socket 31 of a threaded stud 32 extended downwardly therefrom, the bracket being designed to be `mounted on the lower sur# face of an end rail 33 of a bed, such kas the bed 34, with screws 35 orrbygother means.

The base or shoe 21 is formed with a smooth lower surface so that it is adapted to slide or move over a rug, polished iloor, lor the like without damaging the rug or marring the floor and the -uprights 13 vand 14, at one end,and\whichlare integral with a base plate 36 are mounted in the base 21 such as by welding, and the uprights 15 and 16, at the opposite end, which are integral with a base plate 37 are secured in the opposite end, also, such as by welding, as shown at the points 38, and with the cams 11 and 12 pivotally mounted in the uprights with

shafts

39 and 40, on the ends of which the

treadles

23 and 24 are positioned, the cams are readily actuated by the treadles to elevate the ends of the rail 10.

With the ball 30 of the bracket 29 riding on inner edges of llanges at the sides of the U-shaped rail 10 the bracket is free to move laterally and, as an illustration, with the bracket in the position shown in Fig. 6 the cam 11 may be rotated to elevate the end of the rail whereby the ball 30 will slide toward the opposite end, thereby making it possible for the housewife to move a bed from the position shown in full lines in Fig. 2 to that shown in broken lines, Iby pressing downwardly on one of the treadles.

The cams are secured to the shafts, upon which they are mounted by pins 41, as shown in Fig. 5 or by other suitable means. The rail 10 is retained in spaced relation to the uprights with spacing sleeves 42 and the ends of the

pins

19 and 20, which extend through the arcuate slots 17 and 18, are provided with

heads

43 and 44.

As illustrated in Figs. 4 and 6 the threaded upper end of the stud 32 is threaded into hub 45 of the bracket 29, and the stud is provided with a lock nut 46.

The iioor plates 25 and 26 are provided with tracks 47 and 48, respectively and the ends of the tracks are provided with depressions 49 for receiving balls or rollers 50 of casters 51 on lower ends of legs or posts 52 at the head of the bed. l

The Hoor plates 25 and 26 lare connected to the jack with the

tie rods

27 and 28 and the plates are connected together with a rod 51.

With the posts at the head of the bed provided with rollers or casters and with the rollers or casters positioned in the slots or tracks 47 and 48 the foot of the bed may be elevated and moved laterally, such as from the position indicated by the full lines 52 to the position indicated by the broken lines 53 so that space may be provided between the side of the bed and a wall 5,4 or between twin beds, or the like.

It will be understood that'modications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
