United States Patent FURNITURE LEG BUILD UP Robert Manatt Martin, Pella, Iowa Application December 19, 1956, Serial No. 629,382
1 Claim. (Cl. 45-137) This invention relates to a progressive furniture leg build up device and more particularly to interlocking feet for elevating the two rear legs of a bed.
It is generally known that healthful benefits are ob tained by spending at least a period each day with the upper portion of the body at a lower horizontal plane than the normal lower portion of the body. Obviously, with [the head area at such lower level, more nourishing blood than normal is directed to the upper part of the body. Certain muscles, the eyes, the skin, and even the brain, are stimulated. Many practice this procedure by reclining on a declining board for a few minutes each day. This, however, takes valuable time from ones day and is not very comfortable. Furthermore, the time period is so short that progress cannot be made in increasing the angle of decline from the horizontal.
Therefore, one of the principal objects of my invention is to provide a means for elevating the rear end of a bed so that the user of the bed may obtain the beneficial results of reclining with the upper portion at a lower level while sleeping and without taking any time out of the persons waking hours.
A further object of this invention is to provide a means that permits the selective progressive elevation of the rear end of a bed.
More specifically, the object of this invention is to provide a plurality of interlocking ring feet that are adapted for selective use under the two rear legs of a bed for raising the rear end of the bed to a required height.
A still further object of my invention is to provide a furniture leg elevator means comprising a plurality of interlocking plates that prevent the leg from accidentally slipping therefrom.
Still further objects of my invention are to provide a furniture leg elevator means that is economical in manufacture, durable in use and refined in appearance.
These and other objects will be apparent to those skilled in the art.
My invention consists in the construction, arrangements, and combination, of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in my claim, and illustrated in the accompanying drawings, in which:
Fig. 1 is a perspective view of four of my interlocking feet plate rings,
Fig. 2 is a side view of a stack of my integhipking ring plates with sections cut away to more fully illustrate their construction,
Fig. 3 is a side view of the rear end of a bed using one of my elevating interlocking ring plates under each of its legs, and
Fig. 4 is a side view of the rear endof a using I three of my interlocking ring plates under each of its legs.
While I have explained my device as used under the legs of beds, obviously they may be used to elevate other types of devices and furniture.
In the drawings I use the numeral 10 to designate a bed having rear legs 11. Any desired number of my ring foot plates may be placed under each of the rear legs 11. In use, it is customary to start withonly one foot plate under each of the rear legs 11, then after a few Weeks another foot plate is added, and this procedure is continued until the rear end of the bed is at considerable height above its front end. This progressive elevation is desirable because a new user would not be conditioned for extreme angular rest an entire night. I have used the numeral 15 to generally designate each of my plates. These plates 15 are circular and each has a shallow well 16 in its top and having a flat bottom. The upper end portion of the plate that forms the wall around the shallow well is beveled at its rim to extend upwardly and outwardly at 17, as shown in Fig. l. The height of the wall at its inner side and below this bevel is vertical and designated by the numeral 18. The numeral 19 designates a shallow well in the bottom of each of the plates 15. The lower outer circular area of the plate that surrounds the shallow well 19 is beveled to extend upwardly and outwardly at 20 and as shown in Fig. 2. This bevel 20 does not extend to the well 19 and thereby provides the fiat ring contact surface 21. When the first plate is placed under a leg, this part 21 engages the floor 22. If desired, the first plate used need not have the bevel 20, as shown in the lower plate of Fig. 2. The bottom end of the leg 11 is placed in the top shallow well 16 and due to the vertical inner side of the wall 18 the wall 18 will serve as a shoulder to retain the leg on the flat bottom of the well 16. When the second ring foot plate is added, it is merely placed onto the first or adjacent lower one. Its lower bevel 20 engages and nests in the top bevel 17 of the lower foot plate. The contact ring 21 of the upper plate rests on the flat bottom of the top shallow well of the lower plate. This stacking of the plates continues in the same manner until the desired height is obtained. The nesting or conforming of one plate with another prevents any one plate from side lateral movement relative to another. This structure makes for a very rigid safe elevator support for the furniture leg. If desired all the foot ring plates may be duplicates of each other. However, in the drawings I show each plate having an outer side wall tapering upwardly and inwardly, thereby making for a more stable support. Also, if desired, the lower five or so plates 15 of the stack shown in Fig. 2 may be formed as a unit. When such is the case, the progressive build up is first started with the upper or smaller diameter plates and when they eventually equal five or so plates under each bed leg, they are removed and the five or so unit ones used, and the smaller single plates used to build up from the large unit.
Some changes may be made in the construction and arrangement of my furniture leg build up without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim, any modified Patented July 7, 1959 l 0 forms ,of structure, or use of mechanicalequivalents which may be reasonably included within its scope.
In a furniture or like leg build up, a plurality of interlocking nesting foot plate members; each plate member comprising a plate, a shallow well in the top of said plate, a beveled rim at the top area of said shallow well extending outwardly and upwardly, and a beveled rim on the bottom of said plate extending inwardly and downwardlyi said rlrn --terminatin ma flat-bottom cam 51 10 area, whereby when said plate members are" nested, the
