Description

    FIELD OF THE INVENTION
  • The present invention relates, in general, to an aid for lifting furniture and other similar objects and, more particularly, the present invention relates to a furniture lifter for raising a portion of such furniture to place an object under the furniture such as a slide for moving furniture or a protector for the furniture when cleaning rugs.
  • BACKGROUND OF THE INVENTION
  • In both the moving industry and the carpet cleaning industry it is quite common to be faced with the situation in which a relatively large piece of furniture or an appliance has to be moved or raised. With limited manpower it is difficult to pick up the item to place a slide under the furniture so it could be easily moved. A similar problem occurs when carpeting is being cleaned and furniture and the like have to be raised so that a protective pad can be placed under each corner of the item. Many times where a worker may be working alone it is very difficult to raise the item of furniture and still be able to insert what is needed under the furniture at the same time. There have been some lifting units reported in prior art; however most of these are designed more like a jack for motorized equipment such as lawn mowers, while others have specific applications like lifting manhole covers etc. One such prior art apparatus for lifting furniture is found in U.S. Pat. No. 6,354,570 which provides a wheeled lifting device.
  • SUMMARY OF THE INVENTION

Such second means 30 also has a tapered end 34 which permits the apparatus 10 to slide under items even if they sit directly on the floor. It is within the scope of the invention that such tapered end 34 can be formed as part of elongated leg member 32 or it can be a separate unit that is engageable with such elongated leg member 32 as either an insert or a sleeve. FIG. 5 shows tapered end 34 as being round to fit into or around such round elongated leg member 32. However, it is within the scope of the invention that such tapered end 34 and such elongated leg member 32 have a different shape such as being square, rectangular, oval or any other desired shape. The same holds for such elongated rod member and such first means (handle means) 20 wherein these items although previously described as tubular could also have a different shape such as that described above for tapered end 34 and elongated leg member 32.
  • S It is further an embodiment of the invention wherein such tapered end 34 has a covering 38 that slides over the tapered end 34 that is made of plastic or rubber to prevent damage to such item to be lifted. Also, it is within the scope of the invention that such tapered end 34 be made of a different material such as plastic or rubber and is engageable with such leg member 32 as either an insert or a sleeve. It is presently preferred that such plastic end be made of polyethylene. It is within the scope of the invention that such second means 30 be formed of a second predetermined material. It is also an embodiment of the invention that such second means 30 be engageable with such elongated rod member 2 as an insert or a sleeve similar to the way the tapered end 34 is engageable with the elongated leg member 32. However, it is presently preferred that such second predetermined material is the same as the first predetermined material. As stated previously such tapered end 34 of second means 30 could be made of a third predetermined material such as polyethylene.
  • In another embodiment of the invention such first means 20 is offset from said elongated rod member at a predetermined angle as seen in FIG. 2. Also as seen in FIG. 10 it is an embodiment of the invention that such first means 20 is engageable with the first end 4 of the elongated rod member 2 by a ratchet arrangement 26 whereby such first means 20 can be adjusted to a variety of angles. Such first means 20 is substantially an elongated arm member. It is also within an embodiment of the invention that such first means 20 is also adjustable wherein it includes at least two telescoping members. Again, depending on the item to be lifted this would permit the first means 20 to be extended if necessary to position the apparatus 10 so as to reach the base of the furniture or other item.
  • It is within the scope of the invention the tapered tip 34 portion of the second means 30 of the apparatus 10 can be easily replaced with another tapered tip 35 which has a wider tip portion or another tapered tip 37 that is designed to remove nails. In this case the tapered tip is essentially a V-shaped notch and the notch has a taper so as to be able to get under nails. Thus, a carpet installer can use the apparatus 10 to lift furniture and then change the tip portion so as to be able to remove nails. The unit could also be used by roofers to remove nails or shingles. Other applications are envisioned which would also fall within the scope of the invention.
  • In an alternate embodiment of the invention, as shown in FIG. 20, such apparatus 10 has a hanger 52 attached to the elongated rod member 2.
