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.
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.
The present invention provides an apparatus for applying an upward pressure to at least a portion of an object which is at least sufficient to lift such object a predetermined distance. The apparatus comprises at least one elongated rod member formed of a first predetermined material and having a first predetermined shape. A first means is engageable with a first end of the elongated rod member for gripping the apparatus during use and a second means is one of formed integrally with the elongated rod member as a single piece or is engageable at a first end thereof with a second end of the elongated rod member and extending outwardly therefrom for engaging such object to be lifted. A substantially stationary third means is engageable with and disposed closely adjacent an intersection of the second end of the elongated rod member and the first end of the second means, the substantially stationary third means being positioned for supporting and pivoting the apparatus.
In an alternate embodiment there is provided an apparatus for lifting at least a portion of one of furniture, appliances and movable wall structures. The apparatus comprises at least one elongated rod member formed of a first predetermined material and having a first predetermined shape. A handle means is engageable with a first end of the elongated rod member for gripping the apparatus during use and an elongated leg member is one of formed integrally with the elongated rod member as a single piece or is engageable at a first end thereof with a second end of the elongated rod member and extending outwardly therefrom for engaging an item to be lifted. The elongated leg member is adjustable in at least one of an angular mode and a longitudinal mode.
Yet another embodiment of the invention provides an apparatus for lifting at least one of furniture, appliances and movable wall structures. The apparatus comprises at least one elongated rod member formed of a first predetermined material and having a first predetermined shape. An elongated arm member is one of formed integrally with the elongated rod member as a single piece or is engageable at a first end thereof with a first end of the elongated rod member and extending outwardly therefrom for gripping the apparatus during use. The elongated arm member is adjustable in at least one of an angular mode and a longitudinal mode and an elongated leg member is engageable at a first end thereof with a second end of the elongated rod member and extending outwardly therefrom for engaging such item to be lifted.
Still another embodiment of the invention provides an apparatus for applying an upward pressure to at least a portion of an object which is at least sufficient to lift such object a predetermined distance. The apparatus comprises a first elongated rod member formed from a first predetermined material and having a first predetermined shape. A first means is engageable with a first end of the elongated rod member for gripping the apparatus during use. There is a second elongated rod member that is one of being formed integrally with the first elongated rod member as a single piece or is engageable as a separate piece at a first end thereof to a second end of the elongated rod member. An elongated object engaging means is engageable with the second elongated rod member closely adjacent a second end thereof for engaging at least a portion of a bottom surface of such object to be lifted and for exerting an upward pressure to such object. The elongated object engaging means has a predetermined surface bearing area which is at least sufficient to prevent sidewise tipping of the apparatus during use.
In yet another embodiment of the invention there is provided an apparatus which can be used for removing a post imbedded in earth by applying an upward pressure to such post which is at least sufficient to lift such post a predetermined distance said predetermined distance being at least sufficient to enable removing such post by hand. The apparatus comprises a first elongated rod member formed of a first predetermined material and having a first predetermined shape. A handle means is engageable with a first end of the first elongated rod member for gripping the apparatus during use. There is a second elongated rod member that is one of formed integrally with the first elongated rod member as a single piece or engageable as a separate piece at a first end thereof with a second end of the first elongated rod member and extending outwardly therefrom.

In addition to the numerous objects and advantages of the present invention which have been described with some degree of particularity above, it should be both noted and understood that a number of other important objects and advantages of the invention will become more readily apparent to those persons who are skilled in the relevant art of furniture moving from the following more detailed description of the invention, particularly, when such detailed description is taken in conjunction with the appended claims.
Prior to proceeding to the more detailed description of the present invention, it should be noted that for the sake of clarity in understanding the invention, identical components with identical functions have been designated with identical reference numerals throughout the drawing Figures.
Illustrated in the drawing Figures is an apparatus, generally designated 10, for applying an upward pressure to at least a portion of an object which is at least sufficient to lift such object a predetermined distance. Basically the apparatus 10 is used in lifting at least a portion of one of furniture, appliances and movable wall structures. The apparatus 10 comprises at least one elongated rod member, generally designated 2, formed of a first predetermined material and having a first predetermined shape. There is a first means, generally designated 20, engageable at a first end thereof 21, with a first end 4 of elongated rod member 2 for gripping the apparatus 10 during use. It is presently preferred that such second end 22 of the first means 10 includes a rubber grip 24.
A second means, generally designated 30, includes an elongated leg member 32 that is engageable at a first end 31 thereof with a second end 6 of such elongated rod member 2 and extending outwardly therefrom for engaging such item to be lifted.
The apparatus 10 further includes a third means, generally designated 40, that is disposed closely adjacent an intersection of the second end 6 of the elongated rod member 2 and the first end 31 of second means 30, the third means 40 being positioned for providing a-substantially stationary means for sliding, supporting and pivoting the apparatus 10. As used in the present application and in the claims substantially stationary means that in most instances the apparatus will pivot and lift furniture without any appreciable movement. However, it is possible if the lifting point on the furniture or the like is elevated relative to the floor or if the item being lifted is raised a relatively high distance then the substantially stationary third means 40 may slide slightly when the apparatus is tilted fully in raising the furniture.
In an embodiment of the invention such third means 40 is substantially a base member 42. Such base member 42 has rubber or plastic tips 44 on each end to prevent scratching a floor. In a presently preferred embodiment of the invention such base member 42 is positioned substantially perpendicular to such second means 30 on an underside of second means 30. As stated previously such third means 40 is positioned closely adjacent an intersection of the second end 6 of the elongated rod member 2 and the first end 31 of second means 30. In this manner the third means 40 provides essentially a fulcrum for the apparatus 10 to pivot.
In an alternate embodiment of the invention, as seen in
Such apparatus 10 can be formed out of a variety of materials including metal and plastic. It is presently preferred that at least the elongated rod member 2 of such apparatus 10 be formed from a tubular steel and it is also preferred that such material whether it is tubular steel or otherwise possesses strength sufficient to lift at least between about 150 and about 300 pounds.
In an embodiment of the invention as shown in
In an alternate embodiment of the invention, as seen in
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
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
Also in another embodiment of the invention such third means 40 is engageable with such second means 30 by a bolt arrangement 54. Such bolt arrangement 54 could be one of a straight bolt and nut or it could be a U-bolt. In any case the bolt end must be recessed so as to not interfere with the pivoting of the such third means 40 when the apparatus 10 is being used.
