3 Claims.
The present invention relates to manually actuated lifting devices.
During the construction or alteration of a building it often becomes necessary to attach a panel, such as a sheet of wallboard, to the surface of a wall. Generally, this requires that the panel first be lifted off the floor a few inches. Thereafter the panel must be supported in this raised position while it is attached to the wall with suitable fastening means.
The major object of the present invention is to provide a novel device for lifting a panel off the fioor and supporting it against a wall.
Normally, each panel is initially disposed adjacent the wall to which it is to be attached with its lower end spaced one or two inches away from the bottom of the wall and its upper end resting against the wall. It is a more particular object of the present `invention `to provide a lifting device of this nature to effect simultaneous movement of a panel forwardly and upwardly relative to the wall whereby it will be disposed in closely abutting relationship with the wall in its raised position. ln this manner the attachment of the panel to the wall is greatly facilitated.
A further object is to provide a lifting device of this nature which includes novel means permitting the panel to be releasably locked in its raised position.
It is another object of the invention `to provide a lifting device of this nature which is rugged of construction and simple of design whereby it may be sold at low cost and may offer a long service life.
An additional object of the present invention is to provide a lifting device of this nature which is safe and foolproof in use.
It is yet a further object of the invention to provide a lifting device of this nature-which is light in weight and compact in size.
These and other objects of the present invention will become apparent from the following detailed description of a preferred embodiment thereof, when taken in conjunction with the appended drawings wherein:
Figure 1 is a vertical sectional view of a preferred form of device embodying the present invention, showing the device positioned for lifting a panel off a floor; I
Figure 2 is a vertical sectional view similar to Figure i, but showing the panel moved to a raised position; and,
Figure 3 is a top plan view of said device, partly broken away in section,
which is adapted Referring now to the drawings, the preferred form of device embodying the present invention includes a lever member generally designated Iii, below the intermediate portion of which is disposed a fulcrum roller I2. The front end of the lever member Il! is formed with means I4 engageable with the bottom of a nat panel I6, which panel is shown positioned adjacent the wall I8 with its lower end resting upon the surface of a floor I9. The panel I5 is adapted to be raised upwardly from its position of Figure l to its elevated position of Figure 2 by the application of a downwardly directed force indicated by the arrow F in Figure 2, upon the rear end 20 of the lever member I0.
More particularly, the lever member I0 may include a generally flat main body 22 from the sides of which depend a pair of integral side elements 24. The panel engaging means I4 may conveniently comprise a continuation of the main body 22. The fulcrum roller I2 is shown as being of tubular configuration and preferably it will be connected to the lever member I0 by means of a horizontal pin 26. The horizontal pin 26 bridges the side elements 24 at the mid-portion of the lever member. With this arrangement, the roller I2` and the lever member are free to undergo relative longitudinal movement. Preferably, the center of gravity of the lever member will be located forwardly of the pin 26.
Referring now to Figure 1, in operation, the panel engaging means I4 is first urged underneath the bottom of the panel I6, with the fulcrum roller I2 being disposed with its left edge adjacent the pin 26. It should be noted that if the center of gravity of the lever member is located forwardly of the pin 26, it will not be necessary to urge the panel engaging means I4 into place. Instead, this means I4 may be disposed just rearwardly of the bottom of the panel I6, and when the panel is raised slightly, the lever member will self propel itself forwardly so as to position the means I4 underneath the bottom of the panel. This is an important feature since it enables the operator to utilize both of his hands in lifting the panel; the latter often being quite heavy and cumbersome to manipulate. The rear end' 20 of the lever member will be in an elevated position relative to the iioor I9 when the means I4 is under the panel.
After the means I4 has been positioned under the panel, referring to Figure 2, a downwardly directed force F is applied to the rear end 2t of the lever member. The application of such force causes the lever member to pivot around the lthe rear end 32 t will be restrained against forward rolling movefulcrum member l2; the front end of the lever member rising off the floor as the rear end moves downwardly toward the oor. As the front end 26 rises, the panel engaging means I4 lifts the panel i6. During such lifting movement, the weight of the panel I6 will cause the front end of the lever member to simultaneously move forwardly toward the wall I8 at the same time that it moves upwardly relative thereto. During this simultaneous forward and upward movement of the front end of the lever member, the lever member will undergo forward longitudinal movement relative to the roller; the outer periphery of the roller rolling against the underside of the main body 22. By the time the bottom of the panel it has been lifted to the desired height it will also closely abut the surface of the wall i8. The panel may be supported in this raised position so long as the rear end 20 of the lever member is maintained in a depressed position. Thus, the panel may then be attached to the wall by suitable fastening means such as nails, screws. bolts, or the like. It should be observed that once the panel le has been moved to a raised position its weight will tend to urge the lever member rearwardly away from the Wall i3. In order to restrain the lever member against such rearward movement the underside of the main body 22 may include a downwardly extending top element 32 shown welded to the main body. With this arrangement, once the outer periphery of the roller i2 has moved rearwardly relative to the underside of the main body 22 until it engages of the stop element, the roller ment and hence the lever member will be restrained against inadvertent rearward movement away from the wall. Thus, the panel i8 may be held in its raised position against the wall with a minimum amount of attention on the part of the operator.
It should also be observed that although the preferred embodiment of the present invention is particularly adapted for lifting a panel element, other embodiments may be utilized in lifting other types of articles. The present invention in its broadest scope contemplates the provision of a lever member utilized 1n conjunction changes may be made with respect thereto with- Number intermediate portion pin being disposed within the inner periphery of said roller, the application of a downward force upon the rear portion of said lever member causing said lever member to undergo forward movement relative to said lever member, the outer periphery of said roller rolling along the underside of said lever member until said outer periphery engages the rear of said stop element whereby said lever member will effect simultaneous forward and upward movement of said panel until the outer periphery of said roller engages the rear of said stop element, said stop element then restraining said roller against forward longitudinal movement.
2. A device for lifting a panel off a floor and supporting it against a wall, comprising: an elongated body and a pair of integral side elements depending from each side of said main body; a downwardly extending stop element formed on the underside of said main body at the intermediate portion thereof; means formed at the front end of said lever member engageable with the bottom of said panel; a floor-engaging fulcrum roller of tubular configuration disposed below the of said lever member between said side elements; and, a horizontal pin bridging said side elements, the center of gravity of said lever member being disposed forwardly of said pin, and the application of a downward force upon the rear portion of said lever member causing said lever member to undergo forward movement relative to said lever member, the outer periphery of said roller rolling along the underside of said lever member until said outer periphery engages the rear of said stop element whereby said lever member will effect simultaneous forward and upward movement of said panel until the outer periphery of said roller engages the rear of said stop element, said stop element then restraining said roller against forward longitudinal movement.
