8 Claims. 1

This invention relates to improvements in coiled-spring beds, and more particularly to detachable legs useful in converting a conventional coiled-spring mattress of the open metallic frame type into a knockdown bed.

One object of this invention is to convert a conventional open frame coiled-spring mattress into a bed and back again at will.

Another object is a series of legs adapted for rapid attachment to and detachment from the frame of an open coiled-spring mattres to form a knockdown bed.

Another object is a detachable leg construction of but few and simple parts which is inexpensive sential to an understanding of the invention;

Like reference characters designate corresponding parts throughout the several figures of the drawings.

As best disclosed in Figs. 1 and 2, the bed II may consist of conventional open coil coiledspring mattress having the conventional open coil coiled-spring mattress having the conventional angular base frame I2, fashioned out of angle iron or'steel supporting a series of spaced rows of horizontally spaced coiled-springs I3 attached to the upper angle-shaped frame of the bed II to complete acoiled-spring mattress for any conventional type of bed mattress.

At suitably spaced intervals a series of leg assemblies I4, I4 are detachably attached to the base frame [2. As best shown in Fig. 2, each leg assembly I4 may consist of a wooden leg having a slotted guide plate I5 and an angle bracket I6 riveted to the head end of the wooden leg, by means of the rivets I8 and I9 passing through holes drilled in the head end of the leg, through which the rivets I8 and I9 may be inserted and then permanently riveted in one of the oppositely disposed faces of the slotted guide plate I5. The slotted guide plate I5 and the angle bracket I6, are provided with holes arranged in horizontally spaced alignment adapted to receive the shank of a screw bolt I1 which may be secured in place by a suitable nut.

The base frame I2 is of angle iron, and includes an outwardly extending horizontal flange 45, and a depending vertical flange 45 Base frame I 2 is adapted to be supported by the upper extremity of the leg I4 and its vertical flange 46 nests in the slot 43 of the slotted guide plate I5, so that when the screw bolt I1 is inserted through both the angle bracket I6 and the slotted guide plate II, the 'nut may be screwed upon the bolt to anchor the head end of the leg assembly I4 which now nests in the angle defined by the conjunction of the flanges 45 and 46 of the angle-shaped base frame I2. The outwardly extending horizontal flange 45 and the depending vertical flange 46, in conjunction, define an inverted L-shaped base frame I2.

The upper end of the angle bracket I6 is bent over at right angles to form the horizontally disposed portion 40 and the bifurcated fingers 4|, 4|, which overlie the top edge face 41 of the wooden leg. The depending vertical flange 45 of the inverted L-shaped base frame I2 nests in the slot 43 in the guide plate I5 and the horizontal flange 45 of base plate I2 lies between the guide plate I5 and the upstanding holed lug 42 of the angle bracket I6. The marginal side edges of the guide plate I5 are inwardly bent at right angles to the rest of the guide plate I5 to form the horizontally spaced, vertically disposed ears 44, 44. The guide plate I5 and the horizontally spaced cars 44, 44 in conjunction define a U-shaped channel wherein the squared head of the wooden leg I4 nests with a snug flt. The inner vertical edge face of the head end of the leg I4 is rabbeted to conform to the shape of the slots 43, 43 in the guide plate I5, so as to allow the depending vertical flange 46 of base frame I2 to nest between the guide plate I and the ears 44, 44 and the rabbeted side wall of the head end of the leg assembly I4. The shank of the screw bolt II rests upon the upper face of the outwardly extending horizontal flange 45 of the base frame I2, so that the more the screw bolt I1 is tightened in the threaded opening in the guide plate I5, the more securely the head of the leg assembly nests in the angular wall formed by the conjunction of the horizontal flange 45 and the depending vertical flange 46, a

of the inverted L-shaped base frame I2, and the more securely the outwardly extending horizontal flange 45 is anchored between the guide plate I5 and the upstanding holed lug 42.

By assembling four or more leg assemblies -I4 upon the angle-shaped base frame I2 at spaced intervals so as to distribute the load evenly, the open coiled-spring is converted into .a bed, adapted;;to support the conventional mattress, thus dispensing with the frame assembly of the conventional bed. By removing the leg assemblies I4, the bed may be quickly converted back into a conventional open coiled-spring mattress adapted to-be used upon any conventional type of'bed frame.

Figs. 3, 4 and 5 show a modified form of detachable leg assembly 20. a The head of the leg is rabbeted' (Fig. 5') to accommodate the vertical flange 46 of the angle-shaped base frame I2. The leg is also drilled horizontally to form a dowel socket 26 (Fig.5). Preferably the dowel socket 26 does not pass completely through the leg, butterminates short of the opposite face of the leg to provide a positioning stop 25. A socket 24 is drilled; vertically downwards from the top face of the leg 20, in alignment with the dowel socket 26, to form a screw socket 24 which merges at the bottom with'the dowel socket 26.

A metal dowel pin 2Idrilled and tappedto receive two machinescrews 23 is inserted in the dowel socket 26, so that when the dowel pin M is inserted in the dowel socket 2 6 with the end of the dowel pin 2I in abutment with theposi- 'tioning stop 25, one of its tapped openings may be aligned with the screw socket 24 to receive one of the machine screws 23 which may be passed through one of the holes in the yoke '22 and screwed into the tapped hole in the dowel pin 2|. When the angle-shaped base frame I2 is properly seated upon the upper extremity of the leg 26, the-yoke 22 maybe placed across the horizontal face of the channeliron so that the hole in the inner side of yoke'22 is in alignment with the inner tapped hole of the dowel pirrZI, whereupon a machine screw 23 may befinserted through the hole in" the yoke 22 and screwed into the tapped opening in the dowel pin 21. When the rabbeted head end of leg 28 nests properly in the angle-shaped base frame'IZ and both machine screws 23 are properly tightened in the dowel pin 2 I, the angle shaped base frame I2 will be effectively anchored to the head .end of the leg assembly 28.

The modified form shown in Figs. 6 and 7 includesa U-shaped clamp. 30 adapted to straddle the head endof the legof the detachable leg assembly 36. The. inner face of the head end of the leg-36 may be rabbet'edto form a flush seat fortheangle-shaped base frame. I2 when thelatter is seated upon the head end of the leg 36 (see Fig. '7). The head end of the-leg 36 may also be. provided with a'half-yround .slot ex- 4, tending horizontally across the inner face of the leg to form a seat for the semi-cylindrical tip of the U-shaped clamp 30. A half-round nut 3| female threaded at 33, is adapted to be seated 5 in the semi-cylindrical tip of the U-shaped clamp 30. The nut 3I may be separate from the U-shaped clamp 30, but is preferably spot welded or otherwise permanently seated in the semicylindrical tip of the U-shaped clamp 30. The tips of the clamp 30 are provided with horizontally spaced aligned openings 35 adapted to receive a machine screw 32 which may be fastened in the female. threaded opening 33 of the halfround' nut 31. A hole is also drilled through the head end of the leg 36 to receive a machine screw '32; Thus, when the angle-shaped base frame I2 is properly seated upon the head end of the leg 36 the head end of leg 36 nests in the angle in the frame I2, and the U-shaped clamp may be invertedover the angle-shaped base frame I2 .so that the upright legs of the clamp 30,encompass the oppositely disposed-walls. of thehead end of the leg 36, with the opening and the 25 female threaded opening '33 in alignment with the hole in the head end of the leg 36. The machine screw 32 is then passedthrough the aligned holes and screwed into the female.

' frame I2,= the leg assemblies and the angleshapedbaseframe I2 will cooperate when secured together to form. a very rigidspring bed Wooden legs give satisfactory results, but metal legs maybe substitutedif desired. When wooden legs are used, suitable domes or glides 34 may be attached to the legsin the conventional way. Casters, rollers or other conventional forms of devices may be substituted for the domes 34. r
